Detailed Description
The following is a preferred embodiment of the present application, and it should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present application, and these improvements and modifications are also considered as the protection scope of the present application.
Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.
The folding mechanism has functions of rotation, folding, and the like, and thus can be applied to various fields, such as a door lock field, a vehicle field, a machine manufacturing field, an electronic device field, and the like. The folding mechanism can be respectively connected with a structural part through two rotating parts of the folding mechanism, so that the rotation of the two structural parts is realized. A flexible folding electronic device in which the folding mechanism is applied to the electronic device will now be exemplified.
One of the important structural members in flexible folding electronic devices: flexible display panels are an important application technology of Organic Light-Emitting diodes (OLEDs), and have been developed in recent years. Compared with the traditional display screen, the flexible display screen has remarkable advantages, such as lighter and thinner volume and lower power consumption, and benefits from the characteristics of being bendable, having flexibility and the like, the application scene of the flexible display screen is more and more extensive, for example, some mass-produced folding mobile phones based on the flexible display screen appear on the market, and the flexible display screen is mainly divided into two schemes of flexible screen inward folding and flexible screen outward folding. The flexible screen can be effectively protected by the shell, and the influence of external impact and abrasion can be reduced. The advantage of the fold-out is that the bending angle of the flexible screen does not have to be too small and that the half-screen use does not have to unfold the flexible screen.
However, the flexible display screen is a flexible light-emitting layer with a very thin thickness, and the flexible display screen can be conveniently used by a user only depending on a structure with certain rigidity in product application. Therefore, structurally, the flexible display screen needs to be bent by a rigid shell, and the two shells are connected through a folding mechanism. The flexible display screen follows the deformation of the shell and the folding mechanism to realize the change of the unfolding state and the folding state. Therefore, the deformation process of the flexible display screen is the movement process of the folding mechanism.
The flexible folding electronic device usually wants two housings to rotate synchronously to reduce the time required for the flexible folding electronic device to open and fold, so two rotating parts connected with the two housings need to rotate synchronously. But because the gear size is small, the precision is not easy to control, the existence of a virtual position of the gear is easy to cause, and the synchronization effect of the left shell and the right shell is poor. And the unit area of gear engagement is low, the problems of tooth breakage and jamming are easy to occur, and the reliability is low.
In view of the above, in order to solve the above problems, the present application provides a folding mechanism. Referring to fig. 1-2 together, fig. 1 is a schematic perspective view of a folding mechanism according to an embodiment of the present disclosure. Fig. 2 is an exploded view of fig. 1. The present embodiment provides a folding mechanism 1 including two rotating members 10, two rotating shafts 20, and a sliding member 30. One of the rotating shafts 20 is connected to one of the rotating members 10, the other of the rotating shafts 20 is connected to the other of the rotating members 10, and the axial directions D of the two rotating shafts 20 are parallel to each other. The sliding member 30 is movably connected with the two rotating shafts 20. One it drives and is connected to rotate piece 10 the pivot 20 can drive around the axial D rotation of self slider 30 is followed axial D removes, slider 30 is followed axial D removes can drive another the pivot 20 rotates around the axial D of self, and then drives another rotate piece 10 and one the motion of opposite direction is done in step to the rotation piece 10.
The folding mechanism 1 (folding mechanism) is applicable to various structures such as a door lock, a vehicle, various mechanical devices, an electronic device 2, and the like. Alternatively, although the folding mechanism 1 is schematically described as being applied to the electronic device 2 in the present embodiment and in the following, this does not mean that the folding mechanism 1 of the present embodiment is only applied to the electronic device 2, and may be applied to other configurations. Further alternatively, the electronic device 2 provided in the present embodiment includes, but is not limited to, a folding mobile phone, a tablet Computer, a notebook Computer, a palm top Computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a Portable Media Player (PMP), a navigation device, a wearable device, a smart band, a pedometer, and other mobile terminals, and a fixed terminal such as a Digital TV, a desktop Computer, and other fixed terminals. When the folding mechanism 1 is applied to a folding mobile phone, the folding mechanism is a structural unit which is connected with the shell and supports the flexible screen, so that the possible dislocation between the shell and the flexible screen can be reduced.
The two rotors 10 are used to connect different structures, for example, in a folding mobile phone, the two rotors 10 can be connected to a housing, so that the rotors 10 can be driven to rotate when the housing rotates, or the rotors 10 can be driven to rotate when the housing rotates. In the present embodiment, parameters such as the shape, structure, and material of the two rotors 10 are not limited as long as the rotors 10 can be rotated.
Optionally, two rotation pieces 10 are arranged at intervals, that is, there is a distance between two rotation pieces 10, so that when two rotation pieces 10 rotate, the probability of mutual collision can be reduced, the connection between other structural members and the rotation pieces 10 is facilitated, and an assembly space can be reserved for the other structural members. Of course, in other embodiments, the two rotors 10 may be disposed in contact with each other, and this embodiment is schematically described only with the two rotors 10 disposed at an interval.
Alternatively, the two rotating members 10 are arranged in an axisymmetric manner, and each rotating member 10 includes a rotating end 11 and a connecting end 12 which are oppositely arranged, the rotating end 11 is an end portion of the rotating member 10 having a rotation center, and the connecting end 12 is an end portion of the rotating member 10 connected to another structural member (e.g., a housing). The two rotating ends 11 are closer to each other than the two connecting ends 12, that is, the two connecting ends 12 are farther away from each other than the two connecting ends 12, so that the two rotating pieces 10 can be conveniently connected with other structural members respectively, and structural design of the other structural members can be facilitated. Of course, in other embodiments, the two rotation ends 11 may be far away from each other than the two connection ends 12, or the two connection ends 12 may be located on the same side of the two rotation ends 11. The two rotating members 10 may be arranged in a central symmetry, or in the same direction. The present embodiment is schematically illustrated only in the case where the two rotation ends 11 are closer to each other than the two connection ends 12.
Optionally, the rotating component 10 is connected to other structural components in a sliding manner, that is, the rotating component 10 and other structural components can not only rotate synchronously, but also the rotating component 10 can move relative to other structural components to meet specific requirements. For example, when the electronic device 2 is a U-shaped flexible folding screen mobile phone, the rotating member 10 does not need to be slidably connected to the housing, and when the electronic device 2 is a water droplet type flexible folding screen mobile phone, the rotating member 10 can be slidably connected to the housing, so that the housing can be surrounded to form a water droplet shape in the rotating process. Therefore, the folding mechanism 1 provided in the present embodiment may be used for both a U-shaped flexible folding screen mobile phone and a water droplet type flexible folding screen mobile phone, and the present embodiment is not limited herein.
The rotating shaft 20 is a cylindrical shaft, and mainly plays a role of rotation. In the present embodiment, parameters such as the shape, structure, and material of the two rotating shafts 20 are not limited as long as rotation can be achieved. Each of the rotating shafts 20 is connected to one of the rotating members 10, i.e., one of the rotating shafts 20 is connected to one of the rotating members 10 and the other rotating shaft 20 is connected to the other rotating member 10. Since the rotating shaft 20 and the rotating member 10 are engaged with each other, the rotating member 10 is driven to rotate synchronously when the rotating shaft 20 rotates, or the rotating shaft 20 is driven to rotate synchronously when the rotating member 10 rotates. It should be noted that the term "connected" as used herein may be understood as a fixed connection, and may also be other connection methods such as a detachable connection. The rotating shaft 20 and the rotating member 10 are integrally formed when the rotating shaft 20 is fixedly connected to the rotating member 10, but the rotating shaft 20 and the rotating member 10 are artificially differently named for the convenience of understanding. As shown in fig. 2, when the rotating shaft 20 is detachably connected to the rotating member 10, the rotating member 10 can be sleeved on the rotating shaft 20 by using its own connecting hole 13, and the shape of the rotating shaft 20 and the shape of the connecting hole 13 are designed to realize the synchronous rotation of the rotating shaft 20 and the rotating member 10, thereby facilitating the assembly of the folding mechanism 1. Alternatively, the present embodiment is schematically illustrated only by detachably connecting the rotating shaft 20 to the rotating member 10, and as for the specific structure of the rotating shaft 20 and the rotating member 10, the present application will be described in detail later. In addition, the axial directions D of the two rotating shafts 20 are parallel to each other, so that a foundation is provided for the movement of the subsequent folding mechanism 1, and the problems of jamming and the like of the folding mechanism 1 in the movement process are prevented.
Alternatively, the two rotating shafts 20 are spaced apart from each other, so as to avoid the two rotating shafts 20 from colliding with each other when rotating, and to reserve an assembly space for other structural members such as the sliding member 30.
The slide 30 mainly functions as a guide for movement. In the present embodiment, parameters such as the shape, structure, and material of the slider 30 are not limited as long as the slider can move. In this embodiment, the sliding member 30 can be movably connected to the two rotating shafts 20, so as to assemble the sliding member 30 and the rotating shafts 20, and facilitate the subsequent cooperation between the sliding member 30 and the rotating shafts 20, thereby achieving the rotation and movement.
Alternatively, at least a part of the sliding member 30 is disposed between the two rotating shafts 20, and the sliding member 30 is assembled by using the gap between the two rotating shafts 20, thereby reducing the size and space of the folding mechanism 1. Reference herein to "at least a portion of the sliding member 30 being disposed between two rotating shafts 20" is to be understood that all of the sliding member 30 may be disposed between two rotating shafts 20, or a portion of the sliding member 30 may be disposed between two rotating shafts 20, while the remaining sliding member 30 is not disposed between two rotating shafts 20. The present embodiment is schematically illustrated with a portion of the slider 30 disposed between the two shafts 20.
When at least a part of the sliding member 30 is disposed between the two rotating shafts 20, the sliding member 30 can be engaged with the two rotating shafts 20. Alternatively, the sliding member 30 abuts against the two rotating shafts 20, so that the rotation of the rotating shafts 20 is directly transmitted to the sliding member 30, or the movement of the sliding member 30 is directly transmitted to the rotating shafts 20.
Alternatively, the number of the sliding members 30 is one, that is, one sliding member 30 can implement the technical solution of the present embodiment. Of course, a plurality of sliders 30 may be provided in other embodiments, and only one slider 30 is schematically illustrated in the present embodiment.
In the present embodiment, by providing the above three structural members, the two rotating members 10, the two rotating shafts 20, and the sliding member 30 are mutually matched to realize synchronous transmission of the folding mechanism 1, and in this case, the folding mechanism 1 may also be referred to as a folding mechanism 1 having a synchronous function. Specifically, when any one of the two rotating members 10 rotates relative to the sliding member 30, the rotating shaft 20 connected thereto is driven to rotate synchronously around its own axial direction D (as shown by D1 in fig. 1). Therefore, the rotating member 10 and the rotating member 10 rotate in the same direction, i.e., in the direction D1. The rotation of the rotor 10 is achieved by rotating a structural member (e.g., a housing) connected to the rotor 10, so as to rotate the rotor 10, wherein the structural member can move along a predetermined track around the rotation center of the rotor 10. The rotating shaft 20 can cooperate with the sliding member 30 to convert the rotation of the rotating shaft 20 into an axial direction D movement of the sliding member 30, so that the sliding member 30 moves along the axial direction D of the rotating shaft 20 (as shown in D2 in fig. 1), and the axial direction D movement of the sliding member 30 along the rotating shaft 20 can be understood as the movement direction of the sliding member 30 is parallel to the axial direction D of the rotating shaft 20. As shown in fig. 1, the axial direction D of the rotating shaft 20 can be understood as the extending direction of the axis 21 of the rotating shaft 20.
Since the two sides of the sliding member 30 are engaged with the two rotating shafts 20, when the sliding member 30 moves, the sliding member 30 can also be engaged with the other rotating shaft 20 on the other side to convert the movement of the sliding member 30 into the rotation of the other rotating shaft 20 around the axial direction D thereof, so as to rotate the two rotating shafts 20 synchronously. When the other rotating shaft 20 rotates, the other rotating member 10 connected to the other rotating shaft is driven to move in the opposite direction synchronously with the one rotating member 10, so that the two rotating members 10 rotate synchronously (as shown in D1 in fig. 1). When the other rotating member 10 rotates, a structural member (e.g., a housing) connected to the other rotating member 10 is driven to rotate, and finally, the two structural members rotate synchronously. As for how the rotary shaft 20 and the slider 30 cooperate to convert the rotation of the rotary shaft 20 and the movement of the slider 30 to each other, the present application will be described in detail below.
In summary, the present application can achieve synchronous rotation of the two rotating members 10 through the sliding member 30, and when one rotating shaft 20 moves the sliding member 30, the sliding member 30 can immediately rotate the other rotating shaft 20. Because only one part of the sliding part 30 is used as a synchronous structure, the problems of virtual positions, broken teeth and the like which are easily caused when a plurality of gears are arranged and matched with each other in the related technology are avoided, and the reliability and the synchronous effect of transmission are improved. Furthermore, the sliding member 30 is provided to reduce the distance between the two rotation members 10, thereby reducing the bending radius, and the distance between the two rotation members 10 when the folding mechanism 1 is in the folded state.
In addition, two pairs of transmission pairs formed by the two rotating shafts 20 and the sliding piece 30 are only needed during synchronization, the number of the transmission pairs is small, the structure is simple, the size of the folding mechanism 1 can be reduced, and the space occupied by the folding mechanism 1 is reduced. In addition, the folding mechanism 1 only generates two transmissions, so that the transmission efficiency is improved, the accumulated tolerance clearance is reduced, and the rotation idle stroke can be effectively reduced.
Optionally, at least part of the sliding member 30 is provided on one side of the two rotating members 10. Of course, in other embodiments, the connection between the rotating members 10 and the rotating shaft 20 and the positional relationship between the rotating members 10 and the rotating shaft 20 are adjusted such that the sliding member 30 is disposed between the two rotating members 10. In the present embodiment, the positional relationship between the slider 30 and the two rotors 10 is not limited. In the present embodiment and the following description, only the slider 30 is schematically described as being provided on one side of the two rotors 10. When the sliding member 30 is provided on one side of the two rotating members 10, the sliding member 30 moving in the direction D of the axis of the rotating shaft 20 can also be understood as the sliding member 30 moving in a direction approaching or departing from the rotating members 10.
Alternatively, the rotation member 10 may rotate either clockwise or counterclockwise with respect to the sliding member 30.
Alternatively, the two rotating members 10 rotate in opposite directions to move the two rotating members 10 in the same direction or in opposite directions, which can also be understood as the two rotating shafts 20 rotate in opposite directions, that is, the other rotating shaft 20 rotates synchronously in the opposite direction to the rotating direction of the one rotating shaft 20, so as to drive the other rotating member 10 to rotate relative to the sliding member 30 in the opposite direction to the rotating direction of the one rotating member 10. For example, when one of the rotation members 10 rotates clockwise outward, the other rotation member 10 rotates counterclockwise outward. Alternatively, when one of the rotation members 10 rotates clockwise inward, the other rotation member 10 rotates counterclockwise inward. Therefore, the folding mechanism 1 can be unfolded and folded on the basis of synchronous rotation, so that the size of the folding mechanism 1 can be changed under different motion states.
Referring to fig. 3 to 8, fig. 3 is a schematic perspective view of a folding mechanism in an unfolded state according to an embodiment of the present disclosure. Fig. 4 is a side view of fig. 3. Fig. 5 is a schematic perspective view of a folding mechanism in a folded state according to an embodiment of the present application. Fig. 6 is a side view of fig. 5. Fig. 7 is a perspective view of another embodiment of the folding mechanism of the present application in a folded state. Fig. 8 is a side view of fig. 7. In this embodiment, the folding mechanism 1 has the extending direction of the rotating member 10 parallel to two extending states in the arrangement direction of the rotating shafts 20 and the extending direction of the rotating member 10 perpendicular to two folding states in the arrangement direction of the rotating shafts 20, and when the folding mechanism 1 is in the extending states or the folding states, the sliding member 30 and the rotating member 10 have a gap therebetween.
The folding mechanism 1 has two special states during movement, i.e. the turning element 10 during turning: an unfolded state and a folded state. The unfolded state refers to a state in which the two rotation members 10 are arranged in parallel, and the extending direction of the rotation members 10 (as shown by D3 in fig. 3) is parallel to the arrangement direction of the two rotation shafts 20 (as shown by D4 in fig. 3). The extending direction of the rotor 10 can be understood as the direction from the rotating end 11 to the connecting end 12 of the rotor 10 or the direction from the connecting end 12 to the rotating end 11 of the rotor 10. As shown in fig. 3 to 4, the two rotation shafts 20 are arranged in a horizontal direction, so that when the extending direction of the two rotation members 10 is also horizontal, the unfolding state of the folding mechanism 1 can be understood. The folded state refers to a state in which the two rotation members 10 are arranged in parallel and the extending direction of the rotation members 10 (shown as D3 in fig. 5 and 7) is perpendicular to the arrangement direction of the two rotation shafts 20 (shown as D4 in fig. 5 and 7). As shown in fig. 5 to 8, the two rotation shafts 20 are arranged in a horizontal direction, so that when the extending directions of the two rotation members 10 are arranged vertically, the folding state of the folding mechanism 1 can be understood.
When the folding mechanism 1 is in the unfolded state, the area of the folding mechanism 1 can be maximized to have the largest unfolded area. When the folding mechanism 1 is in the folded state, the area of the folding mechanism 1 is the smallest, and can be half of the unfolded area. Therefore, when the folding mechanism 1 is switched between the unfolded state and the folded state, the area of the folding mechanism 1 and the structural members provided on the folding mechanism 1 is also continuously switched between the maximum and the minimum. For example, when the flexible panel is provided on one side of the two rotating members 10, the display surface of the flexible panel is flush with the display surface when the folding mechanism 1 is in the unfolded state, and thus the display area on the side of the folding mechanism 1 is maximized. When the folding mechanism 1 is in a folded state, the flexible screen is bent under the driving of the folding mechanism 1, so that the display area on one side of the folding mechanism 1 becomes smaller and can be half of that when the folding mechanism 1 is unfolded.
Alternatively, when the flexible screen (not shown) is disposed on one side of two rotating members 10, such as above the rotating members 10 in fig. 5-8, the rotating direction of the rotating members 10 may affect the folding manner of the flexible screen. For example, if the rotating member 10 rotates in a direction approaching the flexible screen during the process from the unfolded state to the folded state, the two display surfaces are disposed close to each other, which can be understood as the inward folding of the flexible screen (as shown in fig. 5-6). If the rotating member 10 is rotated in a direction away from the flexible screen, the two display surfaces are away from each other, and the flexible screen is folded outwards (as shown in fig. 7-8).
Referring to fig. 3, 5 and 7, in the present embodiment, when the folding mechanism 1 is in the unfolded state or the folded state, that is, when the folding mechanism 1 is in the limit state, there is a gap between the sliding member 30 and the rotating member 10. In other words, the slider 30 moves to the limit position with a gap from the rotary member 10, and the slider 30 and the rotary member 10 are prevented from colliding with each other, thereby improving the safety of the folding mechanism 1.
Alternatively, the sliding member 30 moves in a direction approaching the rotating member 10 during the process of the folding mechanism 1 from the unfolded state to the folded state; correspondingly, during the process of the folding mechanism 1 from the folded state to the unfolded state, the sliding member 30 moves in a direction away from the rotating member 10. Alternatively, the sliding member 30 is moved in a direction away from the rotating member 10 in the process of the folding mechanism 1 from the unfolded state to the folded state; correspondingly, during the process of the folding mechanism 1 from the folded state to the unfolded state, the sliding member 30 moves in a direction approaching the rotating member 10.
Referring to fig. 9, fig. 9 is an exploded view of a sliding member and a rotating shaft according to an embodiment of the present disclosure. In this embodiment, a first engaging portion 22 is disposed on the peripheral side of the rotating shaft 20, second engaging portions 31 are disposed on two opposite sides of the sliding member 30, and the first engaging portion 22 and the second engaging portion 31 are engaged with each other to convert the rotation of the rotating shaft 20 relative to the sliding member 30 into the movement of the sliding member 30 along the axial direction D of the rotating shaft 20. And converting the movement of the sliding member 30 in the direction of the axis D of the rotating shaft 20 into the rotation of the rotating shaft 20 relative to the sliding member 30.
In order to convert the rotation of the rotating shaft 20 and the movement of the sliding member 30 into each other, a specific embodiment is provided. The first engaging portion 22 may be disposed on the peripheral side of the rotating shaft 20, that is, the first engaging portion 22 is disposed on the peripheral side of both rotating shafts 20. Wherein the peripheral side of the rotating shaft 20 generally refers to the side of the rotating shaft 20 in the circumferential direction. The first engaging portion 22 and the rotating shaft 20 may be an integral structure or a separate structure. When the first matching portion 22 and the rotating shaft 20 are of an integral structure, the first matching portion 22 and the rotating shaft 20 can be prepared through one process, and for convenience of understanding, the first matching portion 22 and the rotating shaft 20 are named differently. When the first engaging portion 22 and the rotating shaft 20 are of a split structure, the first engaging portion 22 and the rotating shaft 20 can be formed separately and then assembled together in various ways. The present embodiment does not limit the fitting relationship between the first fitting portion 22 and the rotating shaft 20.
Since at least a part of the sliding member 30 is disposed between the two rotating shafts 20, the second engaging portion 31 can be disposed on both opposite sides of the sliding member 30 for engaging with the first engaging portion 22 of the rotating shaft 20 on both sides, and the embodiment only shows that one side of the sliding member 30 is disposed with the second engaging portion 31, and the other side should be understood as also being disposed with the second engaging portion 31. Alternatively, the two opposite sides of the sliding member 30 are two opposite sides of the sliding member 30 close to the two rotating shafts 20, so that the first engaging portion 22 is engaged with the second engaging portion 31. Of course, in other embodiments, the two opposite sides of the sliding member 30 may be other sides, and the first engaging portion 22 and the second engaging portion 31 are engaged by using other structural members, but the embodiment is only schematically described with the two opposite sides of the sliding member 30 being the two opposite sides of the sliding member 30 close to the two rotating shafts 20.
The second engaging portion 31 and the sliding member 30 may be an integral structure or a separate structure. When the second engaging portion 31 and the sliding member 30 are of an integral structure, the second engaging portion 31 and the sliding member 30 can be prepared in one process, and for the sake of understanding, the second engaging portion 31 and the sliding member 30 are named differently. When the second engaging portion 31 and the sliding member 30 are of a split structure, the second engaging portion 31 and the sliding member 30 may be formed separately and then assembled together in various ways. The present embodiment does not limit the engagement relationship between the second engagement portion 31 and the slider 30.
In addition, in the present embodiment, the parameters such as the structure, shape, and material of the first engaging portion 22 and the second engaging portion 31 are not limited as long as the first engaging portion 22 and the second engaging portion 31 can be engaged with each other to convert between movement and rotation.
Optionally, the number of the first matching portions 22 and the second matching portions 31 may be multiple, and the multiple first matching portions 22 and the multiple second matching portions 31 may improve transmission accuracy, and have a large matching area and high mechanical reliability. Further alternatively, the number of the first matching portions 22 and the number of the second matching portions 31 may be equal or unequal, which is not limited in this embodiment.
Through the arrangement of the first engaging portion 22 and the engaging portion, when any one of the two rotating members 10 rotates relative to the sliding member 30, the rotating shaft 20 connected thereto can be driven to rotate synchronously. When the rotating shaft 20 rotates, the first engaging portion 22 disposed on the rotating shaft 20 is driven to rotate. Since the first engaging portion 22 and the second engaging portion 31 on the side of the slider 30 can be engaged with each other, the rotation of the first engaging portion 22 can be converted into the movement of the second engaging portion 31, so that the slider 30 can be moved in the axial direction D of the rotating shaft 20. When the sliding member 30 moves, the second engaging portion 31 on the other side of the sliding member 30 can be driven to move, and since the second engaging portion 31 on the other side can engage with the first engaging portion 22 on the other rotating shaft 20, the movement of the second engaging portion 31 is converted into the rotation of the first engaging portion 22, so as to realize the synchronous rotation of the other rotating shaft 20 and the other rotating member 10.
In addition, since the second engaging portions 31 on both sides of the sliding member 30 have the same shape, structure and size, when one rotating member 10 and one rotating shaft 20 rotate in a first direction, the first engaging portion 22 engages with the second engaging portion 31 to move the sliding member 30, and the second engaging portion 31 on the other side engages with the other first engaging portion 22 to rotate the other rotating member 10 and the other rotating shaft 20 in a direction opposite to the first direction, so as to automatically perform unfolding and folding.
Referring again to fig. 9-11, fig. 10 is a side view of fig. 9. Fig. 11 is a schematic perspective view of a rotating shaft according to an embodiment of the present application. In the present embodiment, one of the first and second engagement portions 22 and 31 includes a threaded portion 220, the other of the first and second engagement portions 22 and 31 includes a threaded groove 310, and the extending direction of the threaded portion 220 and the threaded groove 310 is inclined to the rotation direction of the rotation shaft 20.
The present application also provides an embodiment of the first mating portion 22 and the second mating portion 31, which can utilize the threaded portion 220 and the threaded groove 310 to realize the conversion between rotation and movement. Wherein the screw part 220 means a portion protruded at a circumferential side of the rotation shaft 20 or opposite sides of the slider 30, and the screw groove 310 means a portion recessed at the circumferential side of the rotation shaft 20 or opposite sides of the slider 30. The first mating portion 22 includes a threaded portion 220 or a threaded groove 310, and the second mating portion 31 correspondingly includes the threaded groove 310 or the threaded portion 220. Specifically, when the first mating portion 22 is the threaded portion 220, the second mating portion 31 is the threaded groove 310. Alternatively, when the first mating portion 22 is the screw groove 310, the second mating portion 31 is the screw portion 220. In the present embodiment, only the first engagement portion 22 is schematically described as the screw portion 220, and the second engagement portion 31 is schematically described as the screw groove 310.
In addition, the extension directions of the screw part 220 and the screw groove 310 are inclined to the rotation direction of the rotation shaft 20 by the arrangement of the screw part 220 and the screw groove 310. As shown in fig. 10, the rotation directions of the rotating shaft 20 and the rotating member 10 can be understood as vertical rotation, so the extending directions of the threaded portion 220 and the threaded groove 310 are not vertical, but slightly inclined, and the specific inclined angle can be designed according to the requirement. When the rotating member 10 and the rotating shaft 20 rotate, the threaded portion 220 or the threaded groove 310 on the first mating portion 22 is brought into rotational connection with the threaded groove 310 or the threaded portion 220 on one side of the sliding member 30. Since the thread groove 310 and the thread part 220 are obliquely arranged, the thread part 220 contacts with a groove wall of the thread groove 310 during rotation to apply a force to the groove wall, and at least a part of the rotation force in the vertical direction is converted into a moving force in the horizontal direction to move the sliding member 30. The other side of the sliding member 30 is also engaged to convert the moving force into the rotating force, so that the other rotating shaft 20 and the other rotating member 10 rotate.
Optionally, the threaded portion 220 or the threaded groove 310 on the rotating shaft 20 is spirally arranged along the circumferential direction, so that the threaded portion 220 and the threaded groove 310 can be better matched during the rotation of the rotating shaft 20.
Alternatively, as shown in fig. 11, the threaded portion 220 includes a plurality of sub-threaded portions 2200 arranged at intervals, and the plurality of sub-threaded portions 2200 arranged at intervals can also cooperate with the threaded groove 310 to realize the conversion between rotation and movement. And the integral thread part 220 is divided into a plurality of sub-thread parts 2200, so that the preparation difficulty, the cost and the weight of the folding mechanism 1 can be reduced.
Referring to fig. 2 and 9 again, in the present embodiment, the two opposite sides of the sliding member 30 are provided with receiving spaces 32, the second engaging portion 31 is disposed on the inner wall of the receiving space 32, and a portion of the rotating shaft 20 is disposed in the receiving space 32.
The present application details an embodiment in which a partial slide 30 is disposed between two shafts 20. The receiving space 32 is disposed on two opposite sides of the sliding member 30, the second engaging portion 31 can be disposed on the inner wall of the receiving space 32, and a portion of the rotating shaft 20 can be disposed in the receiving space 32, so that the first engaging portion 22 on the rotating shaft 20 engages with the second engaging portion 31 on the inner wall. First, disposing a portion of the rotating shaft 20 in the accommodating space 32 can reduce the dimensions of the rotating shaft 20, the slider 30, and the rotating shaft 20 in the arrangement direction, thereby making the folding mechanism 1 more compact. In addition, the second engaging portion 31 is disposed on the inner wall of the sliding member 30, which can increase the contact area between the first engaging portion 22 and the second engaging portion 31, so that the first engaging portion 22 and the second engaging portion 31 can be better engaged, and the transmission effect can be improved, compared with the case where the second engaging portion 31 is disposed on the side wall 92 without the accommodating space 32.
Optionally, the shape of the inner wall of the accommodating space 32 matches the circumferential shape of the rotating shaft 20, so as to further increase the contact area between the first matching portion 22 and the second matching portion 31, so that the first matching portion 22 and the second matching portion 31 are better matched, and the transmission effect is improved.
Alternatively, the receiving space 32 may be a receiving groove or a receiving hole. For example, the sliding member 30 may be provided with two receiving slots on opposite sides thereof adjacent to the two rotating shafts 20, so that the rotating shafts 20 are disposed in the receiving slots. Or, the sliding member 30 is provided with a receiving hole near the two rotating shafts 20, so that the rotating shafts 20 penetrate through the receiving hole. When the rotating shaft 20 penetrates through the accommodating hole, the hole wall of the accommodating hole can be matched with the rotating member 10 to limit the sliding member 30.
The above description details the connection and position relationship between the rotating shaft 20 and the rotating member 10, and the connection relationship between the rotating shaft 20 and the rotating member 10 will be described below, but the present embodiment is described in terms of a specific structure when the rotating shaft 20 is detachably connected to the rotating member 10.
Referring to fig. 12, fig. 12 is an exploded view of a rotating shaft and a rotating member according to an embodiment of the present disclosure. In this embodiment, the rotating shaft 20 includes a first portion 23 and a second portion 24 connected to each other, the first portion 23 is disposed on the periphery of the first portion 22, at least a portion of the second portion 24 is disposed on the flat structure 240, the rotating member 10 has a connecting hole 13, and the rotating member 10 is sleeved on the flat structure 240 through the connecting hole 13, so that the rotating member 10 and the rotating shaft 20 rotate synchronously.
The rotating shaft 20 in this embodiment includes a first portion 23 and a second portion 24. The first portion 23 and the second portion 24 form the rotating member 10, and the first portion 23 and the second portion 24 may be an integral structure or a split structure. When the first portion 23 and the second portion 24 are of an integral structure, the first portion 23 and the second portion 24 can be prepared in one process, and the first portion 23 and the second portion 24 are named differently for the convenience of understanding. When the first and second portions 23 and 24 are of a split structure, the first and second portions 23 and 24 may be formed separately and then assembled together in various ways. The present embodiment does not limit the fitting relationship between the first portion 23 and the second portion 24. The first engaging portion 22 mentioned above is provided on the peripheral side of the first portion 23, and the shape, structure and size of the first portion 23 are not limited in this embodiment as long as the first engaging portion 22 can engage with the second engaging portion 31 when the rotating shaft 20 is rotated.
As to the structure of the second portion 24, this embodiment has certain requirements that at least a portion of the second portion 24 is provided with a flat-seated configuration 240. The flat structure 240 means that if the circumferential shape of the second portion 24 is circular, the rotating element 10 sleeved on the second portion 24 is difficult to be fixed with the second portion 24, so that the circular shape can be processed into other shapes through various processes (such as milling), thereby fixing or clamping the rotating element 10 during the rotation process. The flat-seated configuration 240 may thus be understood as a configuration that is non-circular in shape. Alternatively, the flat structure 240 may have a shape in the circumferential direction of a square, rectangle, ellipse, pentagram, or the like. On the basis, the rotating element 10 may be provided with a connecting hole 13, and the shape of the connecting hole 13 may be matched with the circumferential shape of the flat structure 240. For example, if the flat structure 240 has a square shape in the circumferential direction, the shape of the connection hole 13 also corresponds to the square shape. If the flat structure 240 has an elliptical shape in the circumferential direction, the shape of the connection hole 13 also corresponds to the elliptical shape. Therefore, the rotating member 10 can be sleeved on the flat structure 240 through the connecting hole 13, so that the rotating member 10 rotates to drive the rotating shaft 20 to rotate, or the rotating shaft 20 rotates to drive the rotating member 10 to rotate. The present embodiment is schematically described only in the case where the flat structure 240 and the connection hole 13 have a square shape.
In addition, the above-mentioned "at least a portion of the second portions 24 are provided with the flat-position structures 240" may be understood as that all of the second portions 24 are provided with the flat-position structures 240, or that a portion of the second portions 24 are provided with the flat-position structures 240, while the rest of the second portions 24 are not provided with the flat-position structures 240. Alternatively, the second portion 24 without the flat site structure 240 may still be circular in shape in the circumferential direction, so as to facilitate the assembly of the rotating shaft 20 to other structural members and achieve the rotating connection. The present embodiment is schematically described only in the case where the flat structure 240 is provided in part of the second portion 24.
Please refer to fig. 13-14, fig. 13 is an exploded view of a sliding member and a rotating shaft according to another embodiment of the present application. Fig. 14 is a partial cross-sectional view of the sliding member and the rotating shaft taken along the direction a-a in fig. 3. In this embodiment, the first engaging portion 22 is provided with a first damping portion 25, the second engaging portion 31 is provided with a second damping portion 33, when the rotating member 10 rotates to a preset angle relative to the sliding member 30, the first damping portion 25 abuts against the second damping portion 33, so that when the rotating member 10 stops rotating, the rotating member 10 keeps a static state relative to the sliding member 30.
As can be seen from the above, when the first engaging portion 22 and the second engaging portion 31 are engaged with each other, the conversion between the rotation of the rotating shaft 20 and the movement of the sliding member 30 can be realized. In this embodiment, the first damping portion 25 may be provided on the first engaging portion 22, the second damping portion 33 may be provided on the second engaging portion 31, and the first damping portion 25 and the second damping portion 33 cooperate with each other to realize the hovering function, and in this case, the folding mechanism 1 may also be referred to as a synchronous mechanism having a certain damping. The first damping portion 25 and the second damping portion 33 are structures having a certain friction coefficient, for example, at least one of the first damping portion 25 and the second damping portion 33 may be made of one or more wear-resistant materials. In addition, the first engaging portion 22 and the first damper portion 25 may be of an integral structure or a split structure. When the first matching portion 22 and the first damping portion 25 are of an integrated structure, the first matching portion 22 and the first damping portion 25 can be prepared through one process, and for convenience of understanding, the first matching portion 22 and the first damping portion 25 are named differently. When the first fitting part 22 and the first damping part 25 are of a split structure, the first fitting part 22 and the first damping part 25 may be formed separately and then assembled together in various ways. Similarly, the second matching portion 31 and the second damping portion 33 may be an integrated structure or a split structure, and this embodiment is not described herein again. In the present embodiment, the fitting relationship between the first fitting portion 22 and the first damper portion 25 and the fitting relationship between the second fitting portion 31 and the second damper portion 33 are not limited.
When an external force is applied to rotate any one of the rotating members 10, the rotating shaft 20 is driven to rotate, and when the rotating shaft 20 rotates, the first matching portion 22 and the first damping portion 25 are driven to rotate. The first fitting portion 22 and the second fitting portion 31 can be fitted to each other to achieve interconversion between rotation and movement. However, when the rotating member 10 is not rotated by the predetermined angle with respect to the sliding member 30, the first damping portion 25 is always rotated and is not in contact with the second damping portion 33. When the rotor 10 rotates to a certain angle relative to the slider 30, the first damper portion 25 and the second damper portion 33 start to be kept in contact with each other. When the rotating member 10 rotates a predetermined angle relative to the sliding member 30, if the rotating member 10 stops rotating, the first damping portion 25 and the second damping portion 33 are abutted against each other, and the friction force and the damping force provided by the first damping portion 25 and the second damping portion 33 can keep the rotating member 10 in a stationary state relative to the sliding member 30. The static state refers to that the rotating part 10 is kept fixed, the gravity of the rotating part 10 cannot fall back, the hovering function is realized, the limiting at a specific angle is realized, and the stability of the folding mechanism 1 is improved. If the rotating member 10 is further rotated, a larger external force is provided, a part of the external force is used to cancel the damping force, and the remaining external force is used to rotate the rotating member 10. Therefore, the present embodiment is not limited to the case where the rotation of the rotor 10 is stopped when the first damping portion 25 and the second damping portion 33 are in contact with each other, but the hovering state may be realized when the rotation of the rotor 10 is stopped at this time. If the force is large enough or continues to be applied, the shaft 20 and the slider 30 can continue to move. In addition, by providing the first damper portion 25 and the second damper portion 33 on the first engaging portion 22 and the second engaging portion 31 when they are engaged with each other, the overall size of the folding mechanism 1 can be further reduced, and the size of the space occupied by the folding mechanism 1 can be reduced.
Particularly, when the first resistorWhen the damper portion 25 and the second damper portion 33 are in contact with each other, the relative interference dimension of the first damper portion 25 and the second damper portion 33 is δ l. As shown in fig. 14, the relative interference dimension is the maximum value of the perpendicular distance between the surface of the first damper portion 25 on the side facing away from the first fitting portion 22 and the surface of the second damper portion 33 on the side facing away from the second fitting portion 31. At this time, the limiting torsion and the damping force F formed by the first damping part 25 and the second damping part 330Associated mainly with δ l, e.g. F0F (δ l). Of course F0And also with the coefficient of friction f, etc. If the user bends the rotating member 10, the torsion F is greater than F0Meanwhile, the rotating shaft 20 can continue to rotate, and the folding mechanism 1 can continue to perform bending movement. If the torque F of the user bending the rotating member 10 is not greater than F0In the meantime, the rotating shaft 20 cannot rotate continuously, and the folding mechanism 1 is in a relatively stable state, thereby realizing the limit of a specific angle.
Alternatively, the above mentioned "preset angle" may be any angle in the range of 0-90 °, and the folding mechanism 1 may realize the hovering function at any angle during the process from the unfolded state to the folded state. Further alternatively, the preset angle may be 0 °, 15 °, 30 °, 45 °, 60 °, 90 °, and so on. For example, the rotating member 10 rotates 0 ° with respect to the sliding member 30, that is, the folding mechanism 1 achieves hovering in the unfolded state. Or the rotating member 10 rotates 90 ° relative to the sliding member 30, that is, the folding mechanism 1 is in the folded state to realize hovering. Or the rotating member 10 rotates 45 ° relative to the sliding member 30, that is, the folding mechanism 1 achieves hovering in the process from the unfolded state to the folded state. In addition, the preset angle may be an angle at which the rotation member 10 rotates clockwise with respect to the sliding member 30, or an angle at which the rotation member 10 rotates counterclockwise with respect to the sliding member 30. At this time, if the angle between the two rotating members 10 is taken as a reference, the folding mechanism 1 can realize the limit and the hovering within the range of 0 to 360 degrees. When the folding mechanism 1 is in the unfolded state, the angle between the two rotating members 10 is 180 °. When the folding mechanism 1 is in the folded state, the included angle between the two rotating pieces 10 is 0 ° or 360 °.
Alternatively, the first mating portion 22 and the second mating portion 31 are a combination of the threaded portion 220 and the threaded groove 310. Therefore, one of the first damping portion 25 and the second damping portion 33 can be disposed on the threaded portion 220, and the other can be disposed on the wall of the threaded groove 310. For example, the first damping portion 25 is provided on the screw portion 220, and the second damping portion 33 is provided on the screw groove 310. Alternatively, the first damper portion 25 is provided in the screw portion 220, and the second damper portion 33 is provided in the screw groove 310. Further optionally, one of the first damping portion 25 and the second damping portion 33 includes a damping fin, and the other includes a limit boss. For example, when the first damping portion 25 is a damping fin, the second damping portion 33 is a limit boss. Alternatively, the first damping part 25 is a limit boss, and the second damping part 33 is a damping fin. In summary, the matching relationship of the present embodiment is the combination of the threaded portion 220 and the threaded groove 310, and the combination of the damping plate and the limiting boss.
In the present embodiment, only the first engagement portion 22 is used as the screw portion 220, the first damping portion 25 is used as the damping fin, the second engagement portion 31 is used as the screw groove 310, and the second damping portion 33 is used as the stopper boss. Further alternatively, the depth of the thread groove 310 is greater than the height of the thread portion 220, so that when the rotating shaft 20 rotates relative to the sliding member 30 and does not rotate by a preset angle, the thread portion 220 rotates in the thread groove 310 and matches with the groove wall of the thread groove 310. However, because the depth of the thread groove 310 is large, the damping fin on the thread part 220 does not contact the bottom wall of the thread groove 310, and the matching between the thread part 220 and the thread groove 310 is not affected, thereby ensuring the normal operation of rotation. However, when the rotating member 10 rotates by a predetermined angle relative to the sliding member 30, not only the threaded portion 220 and the threaded groove 310 are abutted and matched, but also the damping piece and the limiting boss are contacted with each other, thereby achieving the hovering function.
Referring to fig. 14 again, in the present embodiment, the first damping portion 25 includes a plurality of first sub-damping portions 250 disposed at intervals along the axial direction D of the rotating shaft 20, the second damping portion 33 includes a plurality of second sub-damping portions 330 disposed at intervals along the axial direction D of the rotating shaft 20, and when the rotating member 10 rotates to the preset angle relative to the sliding member 30, the first sub-damping portions 250 abut against the second sub-damping portions 330.
The first damping portion 25 and the second damping portion 33 may respectively include a plurality of sub-damping portions, that is, a plurality of first sub-damping portions 250 and a plurality of second damping portions 33, and the plurality of sub-damping portions are disposed at intervals along the axial direction D of the rotating shaft 20. Thus, when the rotating shaft 20 rotates, the plurality of first sub-damping portions 250 also rotate synchronously, and when the rotating member 10 does not rotate relative to the sliding member 30 by the above-mentioned predetermined angle, the plurality of first sub-damping portions 250 are not yet in contact with the plurality of second sub-damping portions 330. When the rotating member 10 rotates relative to the sliding member 30 by the above mentioned preset angle, the plurality of first sub-damping portions 250 can abut against the plurality of second sub-damping portions 330 to further improve the damping force, improve the hovering effect, and make the folding mechanism 1 more stable.
In addition, the above-mentioned contact between the plurality of first sub-damping portions 250 and the plurality of second sub-damping portions 330 means that not all of the first sub-damping portions 250 are always in contact with all of the second sub-damping portions 330, and the number of the first sub-damping portions 250 in contact with the second sub-damping portions 330 is changed during the movement of the slider 30, but the plurality of first sub-damping portions 250 are in contact with the plurality of second sub-damping portions 330 as a whole. For example, the first damping portion 25 includes 5 first sub-damping portions 250 arranged at intervals along the axial direction D of the rotating shaft 20, the second damping portion 33 includes 5 second sub-damping portions 330 arranged at intervals along the axial direction D of the rotating shaft 20, the 5 first sub-damping portions 250 and the 5 second sub-damping portions 330 may abut when abutting for the first time, and the first damping portion 25 and the second damping portion 33 may be arranged in a staggered manner due to the movement of the slider 30 for a certain distance when abutting for the second time, so that the 4 first sub-damping portions 250 and the 4 second sub-damping portions 330 abut. As the slider 30 moves, the number of the first sub-damping portions 250 and the second sub-damping portions 330 abutting against each other may be reduced, and vice versa.
Referring to fig. 15, fig. 15 is a schematic perspective view of a rotating shaft according to another embodiment of the present application. In the present embodiment, at least one of the first damper portion 25 and the second damper portion 33 is provided in plural numbers and spaced apart from each other in the circumferential direction of the rotating shaft 20.
In the present embodiment, the number of the first damper portions 25 may be plural, the number of the second damper portions 33 may be plural, or the number of the first damper portions 25 and the number of the second damper portions 33 may be plural at the same time and may be provided at intervals in the axial direction of the rotating shaft 20. Therefore, the first damper portion 25 and the second damper portion 33 do not contact at the same time, but contact one by one as the rotation continues. Therefore, the suspension device can have a plurality of different preset angles, and the suspension device can be contacted under the plurality of different preset angles, so that the suspension effect is realized. As shown in fig. 15, the first damper portions 25 are 3 in number and are respectively spaced at 30 °. When the first damping portion 25 rotates by 30 ° to suspend, the second damping portion 25 can suspend by 60 ° and the third damping portion 25 can suspend by 90 ° so that the folding mechanism 1 can suspend at three different angles.
Referring to fig. 16, fig. 16 is an exploded view of fig. 14. In this embodiment, the first sub-damping part 250 and the second sub-damping part 330 include a wedge surface 2511, an arc surface 2512, and an abutting surface 2513, and both ends of the arc surface 2512 are respectively connected to the wedge surface 2511 and the abutting surface 2513; when the rotating member 10 rotates to the preset angle relative to the sliding member 30, the two abutment surfaces 2513 abut against each other.
There are multiple surfaces for the first sub-damping part 250 and the second sub-damping part 330: a wedge surface 2511, an arc surface 2512, and an abutting surface 2513, wherein the wedge surface 2511 and the abutting surface 2513 can be connected to the first fitting portion 22 or the second fitting portion 31, and two ends of the arc surface 2512 are respectively connected to the wedge surface 2511 and the abutting surface 2513. The wedge surface 2511, the arc surface 2512, and the abutment surface 2513 share the outer surfaces of the first sub-damping part 250 and the second sub-damping part 330. When the rotating member 10 rotates to a certain angle relative to the slider 30, the first sub-damping portion 250 and the second sub-damping portion 330 may be in contact with each other by two wedge-shaped surfaces 2511, and the wedge-shaped surfaces 2511 are inclined surfaces, so that the first sub-damping portion 250 can better move on the second sub-damping portion 330, and the difficulty in rotating the rotating member 10 is reduced. When the rotating member 10 continues to rotate, the two arc-shaped surfaces 2512 can contact with each other, and the radian of the arc-shaped surfaces 2512 can be utilized to reduce the risk of damage to the first sub-damping portion 250 and the second sub-damping portion 330, thereby prolonging the service life of the first sub-damping portion 250 and the second sub-damping portion 330. When the rotating member 10 rotates to a preset angle, the two abutting surfaces 2513 abut against and cooperate with each other to realize the hovering function. Moreover, if the rotating member 10 wants to rotate, the two arc-shaped surfaces 2512 can also reduce the difficulty of rotating the rotating member.
In addition, at least one of the first sub-damping part 250 and the second sub-damping part 330 has elasticity, and the surfaces of the first sub-damping part 250 and the second sub-damping part 330 are better contacted by the elasticity, so that the rotation of the rotor 10 can be smoothly performed. When the external force is continuously applied after the first damper portion 25 abuts against the second damper portion 33, the first damper portion 25 may be separated from the second damper portion 33 to continue the rotation.
The above description details the related structures of the rotation member 10, the rotation shaft 20, and the sliding member 30. Next, the present application will continue with the description of other structural elements that may also be present in the folding mechanism 1.
Please refer to fig. 17-18 together, fig. 17 is a schematic perspective view of a folding mechanism according to another embodiment of the present application. Fig. 18 is a perspective view of a first assembly according to an embodiment of the present disclosure. In this embodiment, the folding mechanism 1 further includes a first assembly member 40 disposed on one side of the sliding member 30 along the moving direction of the sliding member 30, and one end of the rotating shaft 20 is rotatably connected to the first assembly member 40.
The first fitting member 40 serves as a fixed fitting in the folding mechanism 1, and various structural members can be fitted to the first fitting member 40. In the present embodiment, parameters such as the shape, structure, and material of the first assembly 40 are not limited as long as assembly can be achieved. The present embodiment may rotatably connect one end of the rotating shaft 20 to the first assembly member 40, that is, the rotating shaft 20 is mounted to the first assembly member 40, and the rotating shaft 20 is rotatable relative to the first assembly member 40, so that the first assembly member 40 does not affect the movement of rotation.
Alternatively, a first rotation space 41 may be formed in the first assembly member 40, and one end of the rotation shaft 20 is disposed in the first rotation space 41 to be assembled and rotated. Further alternatively, the first rotation space 41 includes, but is not limited to, a first rotation hole formed at opposite sides of the first assembly 40, or a rotation groove formed at one side of the first assembly 40.
In addition, the first assembly member 40 is disposed on one side of the sliding member 30 along the moving direction of the sliding member 30, which not only facilitates the assembly between the first assembly member 40 and the rotating shaft 20, but also facilitates the subsequent addition of other structural members, such as elastic members, between the sliding member 30 and the first assembly member 40. Optionally, the first fitting member 40 is provided on a side of the sliding member 30 facing away from the rotating member 10.
Referring to fig. 18-20, fig. 19 is a schematic perspective view of a folding mechanism according to another embodiment of the present application. Fig. 20 is a partial exploded view of fig. 19. In this embodiment, the folding mechanism further includes a guide rail 50, an extending direction of the guide rail 50 is parallel to the axial direction D of the rotating shaft 20, and the guide rail 50 cooperates with the sliding member 30 to move the sliding member 30 along the axial direction D.
A guide rail 50 may be further added to the first assembly 40. Wherein the guide 50 mainly serves for limiting and guiding movement. The guide rail 50 may be connected to the first fitting 40. Reference herein to "connected" includes, but is not limited to, fixed or removable connections and the like. When the guide rail 50 is fixedly connected to the first assembly member 40, the fixing member is integrally formed with the first assembly member 40, but for the convenience of understanding, the fixing member is differently named from the first assembly member 40. When the guide rail 50 is detachably connected to the first assembly member 40, as shown in fig. 19 to 20, the guide rail 50 and the first assembly member 40 may be detachably connected to each other by forming screw holes 52 on the guide rail 50 and the first assembly member 40, and then installing screws 51 in the screw holes 52. Of course, in other embodiments, the detachable connection can be realized through a snap connection or the like. In the present embodiment, the shape, structure, material, and other parameters of the guide rail 50 are not limited as long as the guide rail can perform a limiting function.
With respect to the location of the guide 50, the present embodiment may have at least a portion of the guide 50 disposed between the two shafts 20 and disposed on one side of at least a portion of the slider 30, and as can be seen in fig. 19, the guide 50 is disposed above at least a portion of the slider 30. Thus, when the folding mechanism 1 is in motion, the rotating shaft 20 cooperates with the sliding member 30 to move the sliding member 30 along the axial direction D of the rotating shaft 20, and at this time, since the guide rail 50 is disposed above at least a part of the sliding member 30, that is, the guide rail 50 is disposed on a side of the sliding member 30 perpendicular to the moving direction of the sliding member 30, the sliding member 30 is restricted from moving in a direction in which the sliding member 30 is stacked to the guide rail 50 (as shown in D5 in fig. 19), that is, the sliding member 30 is restricted from moving upward. In other words, the slider 30 is prevented from moving in a direction away from the two rotating shafts 20, preventing the slider 30 from being separated from the rotating shafts 20 when moving.
The above-mentioned "at least a part of the guide 50 is disposed between the two rotating shafts 20" can be understood that the whole guide 50 is disposed between the two rotating shafts 20, or a part of the guide 50 is disposed between the two rotating shafts 20, and the rest of the guide 50 is disposed outside the two rotating shafts 20. "the guide rail 50 is provided on one side of at least a part of the slider 30" is understood to mean that the guide rail 50 is provided on one side of the whole slider 30, or the guide rail 50 is provided on one side of a part of the slider 30, while the rest of the sliders 30 and the guide rail 50 have other positional relationships.
In addition, referring to fig. 18 and fig. 20 again, in the present embodiment, the one side of the sliding member 30 is provided with a sliding groove 34, at least a portion of the guide rail 50 is provided in the sliding groove 34, and the extending direction of the sliding groove 34 is parallel to the moving direction of the sliding member 30.
In the present embodiment, a slide groove 34 may be formed on a side of the slider 30 close to the guide rail 50, that is, on an upper side of the slider 30, and at least a part of the guide rail 50 may be provided in the slide groove 34. This not only reduces the overall thickness of the folding mechanism 1, but also allows the guide rail 50 to limit the movement of the slider 30 in a direction away from the two rotation shafts 20, i.e., vertically upward, when the folding mechanism 1 is in motion, since the extending direction of the slide groove 34 is parallel to the moving direction of the slider 30 (as shown by D2 in fig. 20). The groove walls of the slide groove 34 can also be used to limit the movement of the slider 30 in the direction in which the two rotating shafts 20 are aligned (as shown by D4 in fig. 20), i.e., in the horizontal direction. The sliding member 30 can only slide in the extending direction of the sliding groove 34, so that the sliding member 30 can move along the axial direction D of the rotating shaft 20, and the moving effect of the sliding member 30 is improved. Therefore, the guide rail 50 in this embodiment can not only serve as a limit function, but also serve as an auxiliary movement function.
The above-mentioned "at least a part of the guide 50 is disposed in the sliding groove 34" can be understood that the whole guide 50 is disposed in the sliding groove 34, or a part of the guide 50 is disposed in the sliding groove 34. The present embodiment is not limited thereto.
Alternatively, as shown in fig. 18, the first assembly member 40 and the sliding member 30 may be provided with the engaging groove 42 on the same side of the sliding groove 34, so that at least a portion of the guide rail 50 is disposed in the engaging groove 42 and the sliding groove 34, thereby reducing the overall thickness of the folding mechanism 1 and simplifying the structure of the guide rail 50.
Please refer to fig. 18, fig. 21-fig. 22, and fig. 21 is a schematic perspective view of a folding mechanism according to another embodiment of the present application. Fig. 22 is a schematic perspective view of a slider according to an embodiment of the present application. Fig. 21 is a perspective view of the folding mechanism 1 viewed from below. In this embodiment, the folding mechanism 1 further includes a first assembly 40 connected to the guide rail 50, and a first elastic member 60, the rotating shaft 20 is rotatably connected to the first assembly 40, and the first elastic member 60 is disposed between the first assembly 40 and the sliding member 30.
A first elastic member 60 may be further added to the first assembly member 40. The first elastic member 60 has a certain elasticity. Alternatively, the first elastic member 60 includes, but is not limited to, a coil spring, a spiral spring, a plate spring, a disc spring, and the like. Of course, in other embodiments, the first elastic member 60 may be other elastic objects, such as elastic foam, sponge, elastic products made of various polymer materials, and so on. In the present embodiment, the number of the first elastic members 60 may be one or more. The present embodiment is schematically described with only one first elastic member 60.
And, at least a portion of each first elastic member 60 is disposed between the first fitting member 40 and the sliding member 30. Thus, during the movement of the folding mechanism 1, when the rotating member 10 rotates with the rotating shaft 20 to move the sliding member 30, the sliding member 30 will move along the axial direction D of the rotating shaft 20, i.e. the sliding member 30 will move towards the direction away from or close to the first assembly member 40. Therefore, the first elastic element 60 is driven to extend or contract during the movement of the sliding element 30, so that the first elastic element 60 generates a tensile force or a compressive force correspondingly. The first elastic member 60 also gives the slider 30 a repulsive force. Therefore, when the rotating member 10 rotates under the action of external force, the repulsive force can generate a damping effect on the rotation of the rotating member 10, thereby improving the hand feeling of a user. And as the moving distance of the slider 30 increases, the amount of deformation of the first elastic member 60 increases, and the damping effect also increases. In addition, when the external force on the rotating member 10 is removed, if there is no other fixed structure, the folding mechanism 1 has a tendency of returning to its original shape due to the existence of the repulsive force, thereby implementing the function of automatic reset.
The above-mentioned "at least a portion of each first elastic member 60 is disposed between the first assembly member 40 and the sliding member 30" means that each first elastic member 60 is disposed entirely between the first assembly member 40 and the sliding member 30, or a portion of each first elastic member 60 is disposed between the first assembly member 40 and the sliding member 30, and the rest of the first elastic member 60 is located at other positions.
Alternatively, when the rotation member 10 is not rotated in the present embodiment, that is, the initial state of the first elastic member 60 may be the equilibrium state, the first elastic member 60 generates neither the tensile force nor the compressive force. Of course, in other embodiments, if there are other structural members engaged, the first elastic member 60 may be in a compressed state or a stretched state in the initial state. The present embodiment is not limited.
Optionally, as shown in fig. 18, a first guide shaft 35 is disposed on a side of the first assembly member 40 close to the sliding member 30, as shown in fig. 22, a second guide shaft 43 is disposed on a side of the sliding member 30 close to the first assembly member 40, and the first elastic member 60 is sleeved on the first guide shaft 35 and the second guide shaft 43 to achieve positioning assembly, so that the first elastic member 60 is prevented from deforming in the non-axial direction D during deformation, and the deformation stability is improved.
Next, an embodiment in which a portion of each first elastic member 60 is provided between the first fitting member 40 and the sliding member 30 will be described in detail. Referring to fig. 21-22 again, a first groove 36 is formed on a side of the sliding member 30 close to the first assembly member 40, and a portion of the first elastic member 60 is disposed in the first groove 36. In other words, the first groove 36 penetrates through the surface of the sliding member 30 on the side close to the first assembly member 40, that is, the opening direction of the first groove 36 faces the first assembly member 40, and the first groove 36 is used for accommodating part of the first elastic member 60, so that the distance between the first assembly member 40 and the sliding member 30 is reduced, the folding mechanism 1 is more compact, and the overall size of the folding mechanism 1 is reduced.
Alternatively, the second guide shaft 43 may be provided on a groove wall of the first groove 36 to achieve the assembly of the first elastic member 60.
Alternatively, the first groove 36 may be disposed on a side of the sliding member 30 away from the guide rail 50, that is, the first groove 36 may simultaneously penetrate through a surface of the side of the sliding member 30 away from the guide rail 50, and the opening of the first groove 36 may also face away from the guide rail 50 besides facing the first assembling member 40, so as to reduce the assembling difficulty of the second elastic member 80.
Referring to fig. 23 to 26 together, fig. 23 is a schematic perspective view of a folding mechanism according to another embodiment of the present application. Fig. 24 is a schematic perspective view of the other direction in fig. 23. Fig. 25 is a partial exploded view of fig. 23. Fig. 26 is a perspective view of a second assembly according to an embodiment of the present disclosure. Fig. 23 can be understood as a schematic perspective view of the folding mechanism 1 in a plan view. Fig. 24 is a perspective view of the folding mechanism 1 viewed from below. In this embodiment, the folding mechanism 1 further includes a second assembly member 70 connected to the guide rail 50, and a second elastic member 80, the second assembly member 70 is disposed on a side of the sliding member 30 facing away from the first assembly member 40, and the second elastic member 80 is disposed between the second assembly member 70 and the sliding member 30.
A second assembly member 70 and a second elastic member 80 may be further added to the first assembly member 40. The second fitting member 70 serves as a fixed fitting in the folding mechanism 1, and various structural members can be fitted to the second fitting member 70. In the present embodiment, parameters such as the shape, structure, and material of the second assembly 70 are not limited as long as assembly can be achieved. The second assembly member 70 is disposed on a side of the sliding member 30 facing away from the first assembly member 40, the sliding member 30 is disposed between the first assembly member 40 and the second assembly member 70, and an arrangement direction of the first assembly member 40 and the second assembly member 70 is parallel to a moving direction of the sliding member 30 (as shown by D2 in fig. 23), so that not only the assembly of various structural members is facilitated, but also the moving distance of the sliding member 30 can be limited by the first assembly member 40 and the second assembly member 70.
Optionally, at least a portion of the second assembly member 70 is disposed between the two rotation members 10, so that the folding mechanism 1 is more compact and the size of the folding mechanism 1 is reduced. Further alternatively, the shaft 20 may be rotatably coupled to the second fitting 70. Of course, the shaft 20 may be mounted to other members in other embodiments, and the present embodiment is not limited thereto.
Optionally, the guide rail 50 connects the first fitting 40 and the second fitting 70, thereby further improving the connection performance of the guide rail 50. Reference herein to "connected" includes, but is not limited to, fixed or removable connections and the like. When the rail 50 is fixedly connected to the second assembly member 70, the fixing member and the second assembly member 70 are of a unitary structure, but for the sake of understanding, the fixing member and the second assembly member 70 are artificially named differently. When the guide rail 50 is detachably connected to the second assembly member 70, as shown in fig. 23 and 25, the guide rail 50 and the second assembly member 70 may be detachably connected to each other by forming screw holes 52 on the guide rail 50 and the second assembly member 70, and then installing screws 51 in the screw holes 52. Of course, in other embodiments, the detachable connection can be realized through a snap connection or the like.
As for the second elastic member 80, the second elastic member 80 has a certain elasticity. Alternatively, the second elastic member 80 includes, but is not limited to, a coil spring, a spiral spring, a plate spring, a disc spring, and the like. Of course, in other embodiments, the second elastic member 80 can be other elastic objects, such as elastic foam, sponge, elastic products made of various polymer materials, and so on. In the present embodiment, the number of the second elastic members 80 may be one or more. The present embodiment is schematically described with only one second elastic member 80.
And, at least a portion of each second elastic member 80 is disposed between the second fitting member 70 and the sliding member 30. Thus, during the movement of the folding mechanism 1, when the rotating member 10 rotates with the rotating shaft 20 to move the sliding member 30, the sliding member 30 will move along the axial direction D of the rotating shaft 20, i.e. the sliding member 30 will move towards or away from the second assembly member 70. Therefore, the second elastic element 80 is driven to extend or contract during the movement of the sliding element 30, so that the second elastic element 80 correspondingly generates a tensile force or a compressive force. The second elastic member 80 also gives the slider 30 a repulsive force. Therefore, when the rotating member 10 rotates under the action of external force, the repulsive force can generate a damping effect on the rotation of the rotating member 10, thereby improving the hand feeling of a user. And as the moving distance of the slider 30 increases, the amount of deformation of the second elastic member 80 increases, and the damping effect also increases. In addition, when the external force on the rotating member 10 is removed, if there is no other fixed structure, the folding mechanism 1 has a tendency of returning to its original shape due to the existence of the repulsive force, thereby implementing the function of automatic reset.
The above-mentioned "at least a portion of each second elastic member 80 is disposed between the second assembly member 70 and the sliding member 30" means that each second elastic member 80 is disposed entirely between the second assembly member 70 and the sliding member 30, or a portion of each second elastic member 80 is disposed between the first assembly member 40 and the sliding member 30, and the rest of the second elastic member 80 is located at other positions.
Alternatively, when the rotation member 10 is not rotated in the present embodiment, that is, the initial state of the second elastic member 80 may be the equilibrium state, the second elastic member 80 generates neither the tensile force nor the compressive force. Of course, in other embodiments, if other structural members are engaged, the second elastic member 80 may be in a compressed state or a stretched state in the initial state. The present embodiment is not limited.
Optionally, as shown in fig. 26, a third guide shaft 71 is disposed on a side of the second assembly member 70 close to the sliding member 30, as shown in fig. 22, a fourth guide shaft 37 is disposed on a side of the sliding member 30 close to the second assembly member 70, and the second elastic member 80 is sleeved on the third guide shaft 71 and the fourth guide shaft 37 to achieve positioning assembly, so that the second elastic member 80 is prevented from deforming in the non-axial direction D during deformation, and the deformation stability is improved.
Next, an embodiment in which a portion of each second elastic member 80 is provided between the second fitting member 70 and the sliding member 30 will be described in detail.
Referring to fig. 22 and fig. 24 again, in the present embodiment, a second groove 38 is disposed on a side of the sliding member 30 close to the second assembly member 70, and a portion of the second elastic member 80 is disposed in the second groove 38. In other words, the second groove 38 penetrates through the surface of the sliding member 30 on the side close to the second fitting member 70, that is, the opening direction of the second groove 38 faces the second fitting member 70, and the second groove 38 is used for accommodating part of the second elastic member 80, so that the distance between the second fitting member 70 and the sliding member 30 is reduced, the folding mechanism 1 is more compact, and the overall size of the folding mechanism 1 is reduced.
Alternatively, the fourth guide shaft 37 may be provided on a groove wall of the second groove 38 to achieve the assembly of the second elastic member 80.
Alternatively, the second groove 38 may be disposed on a side of the sliding member 30 away from the guide rail 50, that is, the second groove 38 may simultaneously penetrate through a surface of the side of the sliding member 30 away from the guide rail 50, and the opening of the second groove 38 may also face away from the guide rail 50 besides facing the second assembling member 70, so as to reduce the assembling difficulty of the second elastic member 80.
Alternatively, the first groove 36 and the second groove 38 are spaced apart, that is, the first groove 36 and the second groove 38 can be separated by a portion of the sliding member 30, so that the first elastic member 60 and the second elastic member 80 disposed in the first groove 36 and the second groove 38 are not affected by each other.
In this embodiment, the folding mechanism 1 has the extending direction of the rotating member 10 parallel to two, the unfolding state when the arranging direction of the rotating shaft 20 is extended, and the extending direction of the rotating member 10 perpendicular to two, the folding state when the arranging direction of the rotating shaft 20 is extended, when the folding mechanism 1 is in the unfolding state or when the folding state, the first elastic member 60 and the second elastic member 80 are both in the compression state and have the same elastic coefficient.
The unfolding state and the folding state of the folding mechanism 1 are described in detail above, and the description of the embodiment is omitted here. As can be seen from the above, the folding mechanism 1 may further include a first assembly member 40, a second assembly member 70, a first elastic member 60, and a second elastic member 80, wherein the first elastic member 60 is located between the first assembly member 40 and the sliding member 30, and the second elastic member 80 is located between the second assembly member 70 and the sliding member 30, and the first elastic member 60 and the second elastic member 80 are deformed correspondingly to have different deformation states during the non-movement and the entire movement of the sliding member 30.
The entire movement process of the slider 30 mentioned above may be understood as a process of the folding mechanism 1 from the folded state to the unfolded state, or a process of the folding mechanism 1 from the unfolded state to the folded state. This embodiment can make both the first elastic member 60 and the second elastic member 80 in a compressed state when the folding mechanism 1 is in the unfolded state or the folded state. It can also be understood that the folding mechanism 1 is in a compressed state at the beginning and the end of the whole movement process, and therefore the first elastic element 60 and the second elastic element 80 are in a compressed state in the whole process.
And since the above description has mentioned that the sliding member 30 is disposed between the first assembly member 40 and the second assembly member 70, the first groove 36 and the second groove 38 are disposed on opposite sides of the sliding member 30, and one end of the first elastic member 60 is disposed in the first groove 36 and the other end is disposed on the first assembly member 40. A second resilient member 80 has one end received in the second recess 38 and the other end received on the second fitting 70. At least a portion of the first elastic member 60 is disposed opposite at least a portion of the second elastic member 80. In this way, since the first elastic element 60 and the second elastic element 80 are always in a compressed state, the first elastic element 60 and the second elastic element 80 have an initial pre-tightening force. For example, the first elastic element 60 has an initial preload G01The second elastic member 80 has an initial pre-tightening force G02So that the two elastic members are folded in pairsDamping force G of the entire mechanism 10Comprises the following steps: g0＝G01+G02。
In addition, since the folding mechanism 1 changes the compression force of the first elastic element 60 and the second elastic element 80 during the movement process, i.e. the moving process of the sliding element 30, the pre-tightening force of the first elastic element 60 and the second elastic element 80 is changed. However, since the elastic coefficients of the first elastic member 60 and the second elastic member 80 are the same, the changed forces of the first elastic member 60 and the second elastic member 80 are the same, and the directions are opposite, so that the sum of the pre-tightening forces of the changed first elastic member 60 and the changed second elastic member 80 is constant G0. Therefore, the folding mechanism 1 can have certain damping in the whole movement process, the torsion is stable, the hand feeling of a user is smooth and not loose when the user bends, the force is always the same, and the experience of the user when the user bends is improved.
The above mentioned references the torque forces F and F of the rotating member 10 during the rotating bending0In this embodiment, the damping force G of the first elastic material 60 and the second elastic material 80 to the entire folding mechanism 1 is introduced0If the torque force F is greater than F0And G0In addition, the rotating shaft 20 can continue to rotate, and the folding mechanism 1 can continue to perform the bending motion. If the torque F is not greater than F0And G0And if the rotating shaft 20 cannot rotate continuously, the folding mechanism 1 is in a relatively stable state, so that hovering and limiting at a specific angle are realized.
Optionally, the initial preload G of the first elastic member 6001The second elastic element 80 has an initial pre-tightening force G02The same or different, and the present embodiment is not limited thereto.
In addition, referring to fig. 24 again, in the present embodiment, the movement limit stroke of the sliding member 30 in the axial direction D of the rotating shaft 20 is smaller than the maximum deformation amount of the first elastic member 60 and the maximum deformation amount of the second elastic member 80.
Besides the above-mentioned relationship of initial pre-tightening force, the first elastic element 60 and the second elastic element 80 can be limited according to the maximum deformation amount, i.e. the limit stroke, of the first elastic element 60 and the second elastic element 80 in this embodimentThe limit travel of the slider 30. Because the components, materials, sizes and process preparation methods of all the elastic parts are different, each elastic part has the maximum deformation amount of the elastic part. For example, the first elastic member 60 has a first limit stroke m1, i.e., the maximum amount of deformation of the first elastic member 60 itself is reached. The second elastic member 80 has a second limit stroke m2, i.e. up to the maximum amount of deformation of the second elastic member 80 itself. When the sliding element 30 moves in the axial direction D (as shown in D2 in fig. 24) of the rotating shaft 20, the first elastic element 60 and the second elastic element 80 are driven to deform and approach to their respective limit strokes, and in this embodiment, the movement limit stroke of the sliding element 30 is smaller than the minimum value of the first limit stroke and the second limit stroke, so that the sliding element 30 does not exceed the limit stroke of any one of the elastic elements when moving, and the damping force G generated by the two elastic elements is ensured, thereby ensuring that the damping force G is generated by the two elastic elements0Keep unchanged and improve the damping force G0Stability of (2).
Referring to fig. 27, fig. 27 is a schematic perspective view of a portion of a folding mechanism according to another embodiment of the present application. In this embodiment, the folding mechanism 1 further includes a rotating member 100 rotatably connected to the first assembly member 40, the rotating member 100 and the rotating member 10 are both used for connecting a housing and can rotate under the rotation of the housing, and a rotation center line 111 of the rotating member 100 coincides with or has a distance from the axis 21 of the rotating shaft 20.
The folding mechanism 1 may further include a rotary member 100 in addition to the rotary member 10. The rotary member 100 mainly functions as the rotary member 10, and also functions to rotate and revolve. The rotating direction of the rotating element 100 is parallel to the rotating direction of the rotating element 10 (as shown in D1 in fig. 30), so that the rotating element 100 and the rotating element 10 can be connected to the housing together, and can move in cooperation with the housing to rotate under the driving of the housing, thereby improving the stability of the movement of the housing. The rotating member 100 is rotatably coupled to the first assembly member 40, that is, the first assembly member 40 is not only rotatably coupled to the rotating shaft 20, thereby rotatably coupling the rotating member 10, but also rotatably coupled to the rotating member 100, such that both the rotating member 10 and the rotating member 100 are rotated based on the first assembly member 40. As can be seen from the above, the rotating member 10 rotates to drive the rotating shaft 20 to rotate, and the rotating shaft 20 rotates around the axis 21 of the rotating shaft 20. The extending direction of the axis 21 mentioned here can be understood as the axial direction D of the rotating shaft 20 mentioned above, both of which are substantially one meaning.
The rotating member 100 rotates around a rotation center line 111 when rotating on the first assembly member 40, where the rotation center line 111 may be an axis of the rotating member 100 itself, or an axis of the rotating member 100 sleeved on a structural member, for example, the rotating member 100 is sleeved on the shaft sleeve 110, so that the rotation center line 111 is an axis of the shaft sleeve 110. For the axis 21 and the rotation center line 111 to have various positional relationships, for example, the axis 21 and the rotation center line 111 can be arranged in a coincident manner, that is, the rotation axis of the rotation member 10 and the rotation axis of the rotation member 100 are arranged concentrically, in other words, the rotation member 10 and the rotation member 100 move concentrically, when the rotation member 10 and the rotation member 100 rotate at the same angle, no displacement deviation is generated, and this case can be applied to a U-shaped flexible folding screen mobile phone. When the distance is provided between the axis 21 and the rotation center line 111, that is, the rotation axes of the rotating element 10 and the rotating element 100 are not arranged concentrically, in other words, the rotating element 10 and the rotating element 100 move eccentrically, when the rotating element 10 and the rotating element 100 rotate by the same angle, a displacement deviation will be generated between the rotating element 10 and the rotating element 100, which can be applied to a water drop type folding screen mobile phone, the direction of the housing in the rotating process is controlled by the rotating element 10, and the relative distance between the folding mechanism 1 and the set point of the housing is controlled by the rotating element 100 to limit the movement of the housing in the radial direction. The present embodiment is schematically described only with the axis 21 coinciding with the rotation center line 111. As to how the folding mechanism 1 is fitted to the housing when the present embodiment is applied to a flexible folding screen mobile phone of a water droplet type, the present embodiment will not be described in detail here.

Fig. 29 is an exploded view of a rotating member and a first assembly member according to another embodiment of the present disclosure. In this embodiment, the folding mechanism 1 further includes a shaft sleeve 110 rotatably connected to the first assembly member 40, and the shaft sleeve 110 is sleeved on the rotating member 100; alternatively, one of the first assembly member 40 and the rotary member 100 is provided with a rotary block 120, and the other of the first assembly member 40 and the rotary member 100 is provided with a rotary groove 46.
As can be seen from the above description, the rotating member 100 can be rotatably connected to the first assembly member 40 regardless of whether the rotating member 100 and the rotating member 10 are concentrically disposed. The present embodiments thus provide a number of implementations. In one implementation, a sleeve 110 may be additionally provided, such that the sleeve 110 is rotatably connected to the first assembly member 40, and the rotating member 100 is sleeved on the sleeve 110, such that the rotating member 100 can rotate relative to the first assembly member 40.
Alternatively, a rotation hole 130 may be formed in the rotation member 100, and the rotation member 100 is sleeved on the shaft sleeve 110 through the rotation hole 130. And a rotation space 44 is opened at the first assembly member 40, a second rotation space 45 is opened at a side wall 92 of the rotation space 44, and an end of the shaft sleeve 110 is disposed in the second rotation space 45, thereby completing the assembly. One end of the shaft sleeve 110 may be disposed in the second rotating space 45, and the other end and the rotating shaft 20 may be disposed in the first rotating space 41. The rotating member 10 and the rotating member 100 may be disposed concentrically or eccentrically. Further alternatively, when the rotating member 10 is disposed concentrically with the rotating member 100, the sleeve 110 may also be a part of the rotating shaft 20, that is, the rotating shaft 20 penetrates through the first rotating hole of the first rotating space 41 and is disposed in the second rotating space 45, and then the part of the rotating shaft 20 located between the first rotating space 41 and the second rotating space 45 may be understood as the sleeve 110.
In another implementation, rotation may be achieved in the form of a rotation block 120 or a rotation slot 46. For example, the first assembly member 40 may be provided with a rotation block 120 and the rotation member 100 may be provided with a rotation groove 46. Alternatively, the first fitting 40 may be provided with the rotation groove 46, and the rotating member 100 may be provided with the rotating block 120. The position of the rotation block 120 in the rotation groove 46 is not limited in the present embodiment, and the present embodiment is schematically described only by providing the rotation groove 46 in the first assembly 40 and providing the rotation block 120 in the rotation member 100.

The rotor 10 is shown in phantom in a side view in this embodiment. Therefore, the synchronous reliability and synchronous effect of the electronic equipment 2 can be improved, the transmission efficiency is improved, and the rotation idle stroke is reduced. In addition, because only the sliding part 30 is needed to realize synchronous transmission, the bending radius can be reduced, the distance between the two halves of the flexible screen 3 is reduced, and the appearance performance is improved. At this time, the flexible folding mobile phone can also be called as a page type flexible screen 3 folding mobile phone.
In the present embodiment, the number of folding mechanisms 1 in the electronic device 2 is not limited, and for example, the number of folding mechanisms 1 in the electronic device 2 may be one or more.
Please refer to fig. 31-33 together, and fig. 31 is a schematic view of a partial structure of an electronic device according to an embodiment of the present application. Fig. 32 is a partial exploded view of fig. 31. FIG. 33 is an exploded view of the bracket, the rotating shaft, and the rotating member according to an embodiment of the present application. In this embodiment, the folding mechanism 1 further includes a bracket 90, which is disposed on a side of the guide rail 50 facing away from the sliding member 30, and can also be understood as being disposed on a side of the folding mechanism 1 facing away from the flexible screen. The first assembly member 40 and the second assembly member 70 are mounted to the bracket 90; the rotating shaft 20 is rotatably connected to the bracket 90, or the rotating shaft 20 is rotatably connected to the second assembly member 70.
The bracket 90 mainly functions as a support and a fixing, and the bracket 90 can be disposed on a side of the guide rail 50 facing away from the sliding member 30, that is, the sliding member 30 is disposed between the guide rail 50 and the bracket 90, and the bracket 90 can be used to limit the movement of the sliding member 30 toward the bracket 90. In addition, in the present embodiment, the first assembly member 40 and the second assembly member 70 may be mounted on the bracket 90, so that the first assembly member 40 and the second assembly member 70 may be fixed, and the structural limitation of each structural member mounted on the first assembly member 40 and the second assembly member 70 may be realized.
Alternatively, as shown in fig. 32, a screw hole 52 may be opened at a corresponding position of the bracket 90, and a screw 51 is installed in the screw hole 52 of the guide rail 50, the first assembly member 40, and the bracket 90 to assemble the guide rail 50, the first assembly member 40, and the bracket 90. Meanwhile, the screws 51 can also be arranged in the screw holes 52 of the guide rail 50, the second assembly part 70 and the bracket 90 to realize the assembly of the guide rail 50, the second assembly part 70 and the bracket 90, and finally realize the stable connection of the structural parts and the bracket 90.
As can be seen from the above, one end of the rotating shaft 20 is rotatably connected to the first assembly 40, and the other end of the rotating shaft 20 is rotatably connected to the bracket 90 and also rotatably connected to the second assembly 70. This embodiment is not limited to this. The present embodiment is schematically described only with the other end of the rotating shaft 20 rotating the connecting bracket 90. Alternatively, as shown in fig. 33, the bracket 90 is provided with a rotating seat 93, the rotating seat 93 is provided with a second rotating hole 930, and the other one of the rotating shafts 20 passes through the second rotating hole 930 to realize the rotation of the rotating shaft 20, so as to realize the limiting of the rotating member 10 in the non-rotating direction. Further alternatively, the rotating seat 93 is provided on the body 91 of the bracket 90. Further alternatively, the rotating shaft 20 includes a first portion 23 and a second portion 24, a portion of the second portion 24 is provided with the flat structure 240, the remaining second portions 24 extend through the second rotating hole 930 to rotatably connect the bracket 90 to the rotating shaft 20, and the remaining second portions 24 may be understood as the rotating portions 241. Specifically, the shape of the second rotation hole 930 is circular, and the shape of the rotation portion 241 in the circumferential direction is also circular.
Optionally, the flat structure 240 is disposed on a side of the rotating portion 241 close to the sliding element 30, and since the rotating portion 241 is matched with the rotating seat 93, when the rotating element 10 is sleeved on the flat structure 240, the rotating seat 93 can be used to limit the rotating element 10, so as to prevent the rotating element 10 from being separated from the rotating shaft 20. Further alternatively, the flat structures 240 are disposed on two opposite sides of the rotating portion 241, so that the rotating member 10 can be limited by the rotating seat 93, and the rotating member 10 can also be used to limit the rotating shaft 20. And the structure of the rotation member 10 may be adaptively changed. The present embodiment is schematically described only with the flat structure 240 provided on opposite sides of the rotating portion 241.
Please refer to fig. 27, 34-35 together, fig. 34 is a schematic perspective view of a portion of the folding mechanism according to an embodiment of the present application when folded inwards. Fig. 35 is a schematic perspective view of a portion of a folding mechanism according to an embodiment of the present application when folded outward. In this embodiment, the bracket 90 includes a main body 91 and a side wall 92 connected to the periphery of the main body 91 in a bending manner, the main body 91 and the side wall 92 form an installation space 94, the first assembly member 40 and the second assembly member 70 are installed on the main body 91, an avoidance space 95 is provided on one side of the side wall 92 away from the main body 91 and one side of the side wall 92 away from the installation space 94, and a part of the rotating member 10 can be disposed in the avoidance space 95.
For the holder 90, its shape may not be straight, but includes a body 91 and a sidewall 92. Wherein the body 91 is understood to be the bottom wall of the bracket 90, which is mainly used for mounting various structural members, such as the first assembly member 40 and the second assembly member 70, and so on. The sidewall 92 is bent and connected to the periphery of the body 91 and is protruded therefrom. The side wall 92 and the body 91 may enclose a mounting space 94 for better mounting of structural members of the protective bracket 90, and the side wall 92 may also be used to cooperate with other structural members such as a housing. The body 91 and the side wall 92 may be formed in an integral structure or in a separate structure. When the body 91 and the sidewall 92 are of an integrated structure, the body 91 and the sidewall 92 can be prepared through one process, and for convenience of understanding, different names are given to the body 91 and the sidewall 92 by people. When the body 91 and the sidewall 92 are of a split structure, the body 91 and the sidewall 92 can be formed separately and then assembled together in various ways. In the present embodiment, the fitting relationship between the main body 91 and the side wall 92 is not limited.
As can be seen from the above, the folding mechanism 1 has an unfolded state and a folded state, as shown in fig. 27, the unfolded state is a state when the included angle is 180 ° when the two rotating members 10 are horizontally disposed, and the folded state is a state when the included angle is 0 ° or 360 ° when the two rotating members 10 are vertically disposed, that is, the inward folding and the outward folding mentioned above. As shown in fig. 34, when the connecting end 12 of the rotating member 10 is rotated in a direction away from the main body 91 in the process from the unfolded state to the folded state, it can be regarded as the inward folding of the folding mechanism 1. As shown in fig. 35, if the connecting end 12 of the rotating member 10 rotates in a direction approaching the main body 91 and then rotates in a direction away from the main body 91, it can be considered as the outward folding of the folding mechanism 1. When the folding mechanism 1 is folded inward, the side wall 92 does not affect the rotation of the rotating member 10, but when the folding mechanism 1 is folded outward, the rotation of the rotating member 10 is affected by the presence of the side wall 92. Therefore, the present embodiment may provide the sidewall 92 with an avoiding space 95, and specifically, the sidewall 92 may provide the side away from the body 91 and the sidewall 92 may provide the side away from the mounting space 94 with the avoiding space 95, that is, the upper surface of the sidewall 92 and the outer surface of the sidewall 92 provide the avoiding space 95. Therefore, when the rotating piece 10 rotates, the avoiding space 95 can be used for avoiding the rotating piece 10, and part of the rotating piece 10 can be arranged in the avoiding space 95, so that the problems of jamming and the like during rotation are prevented. Therefore, the folding mechanism 1 provided by the embodiment has two different folding states, and can be folded inwards or outwards, so that the diversity of rotation of the folding mechanism 1 is improved.
Optionally, the avoidance space 95 includes, but is not limited to, an avoidance slot or an avoidance hole. When the avoiding space 95 is an avoiding groove, the avoiding groove can be further disposed on one side of the side wall 92 close to the mounting space 94, that is, the avoiding groove penetrates through two opposite sides of the side wall 92, so as to further improve the avoiding effect. Further alternatively, as shown in fig. 33, when the avoiding space 95 is an avoiding groove, the side of the rotating member 10 close to the side wall 92 may also be adapted to be provided with an avoiding groove, or the side of the rotating member 10 close to the side wall 92 is protruded toward the direction away from the side wall 92 to enclose the avoiding space 14. In other words, both the side wall 92 and the rotor 10 may be provided, and the side wall 92 and the rotor 10 may be matched to further improve the avoidance effect. In the present embodiment, only the escape space 95 is used as an escape groove, and the side of the rotor 10 close to the side wall 92 is protruded in a direction away from the side wall 92.
When dodging space 95 for dodging the hole, dodging the hole and can running through lateral wall 92 and body 91, forming the through-hole that runs through from top to bottom, the size of dodging space 95 is improved to further improve and dodge the effect. As for whether the avoiding space 95 is an avoiding groove or an avoiding hole, the present embodiment is not limited, and may be set according to the structure, size, and the like of the rotating member 10 as long as the folding mechanism 1 can be folded outward.
The above-mentioned angle from the direction of rotation of the rotary member 10 when rotating describes the difference between the inward folding and the outward folding of the folding mechanism 1. The present embodiment will discuss the difference between the fold-in and fold-out of the folding mechanism 1 again from the static point of view. In this embodiment, the folding mechanism 1 has an unfolded state when the extending direction of the rotating member 10 is parallel to the arrangement direction of the two rotating shafts 20, and a folded state when the extending direction of the rotating member 10 is perpendicular to the arrangement direction of the two rotating shafts 20, when the folding mechanism 1 is in the unfolded state, the rotating member 10 has a first surface 15 and a second surface 16 that are opposite to each other, and the first surface 15 is far away from the body 91 compared with the second surface 16; when the folding mechanism 1 is in the folded state, the two first surfaces 15 are close to each other, or the two second surfaces 16 are close to each other.
As shown in fig. 27, when the folding mechanism 1 is in the unfolded state, that is, the two rotating members 10 are unfolded and form an included angle of 180 °, the rotating members 10 have a first surface 15 and a second surface 16 which are opposite to each other, the first surface 15 is far away from the body 91 compared to the second surface 16, the first surface 15 is an upper surface of the rotating member 10, and the second surface 16 is a lower surface of the rotating member 10. After the first surface 15 and the second surface 16 of the rotating member 10 are defined, when the folding mechanism 1 is in the folded state, the folding mechanism 1 has two folding modes: inward folding and outward folding. As shown in fig. 34, when the folding mechanism 1 is folded inward, the two first surfaces 15 are closer to each other and the two second surfaces 16 are farther from each other. As shown in fig. 35, when the folding mechanism 1 is folded outwardly, the two second expressions are now close to each other and the two first surfaces 15 are far from each other. Alternatively, when the folding mechanism 1 is in the unfolded state, the two first surfaces 15 are arranged flush.
Referring to fig. 32 again, in the present embodiment, the main body 91 is provided with two limiting portions 96 arranged at intervals along the moving direction of the sliding member 30, and the first assembly member 40 is arranged between the two limiting portions 96.
In this embodiment, two spacing portions 96 may be disposed at intervals on the main body 91, the arrangement direction of the two spacing portions 96 is parallel to the moving direction of the slider 30 (as shown by D2 in fig. 32), and the extension direction of the two spacing portions 96 is parallel to the arrangement direction of the two rotating shafts 20 (as shown by D4 in fig. 32). The first fitting 40 is provided between the two stopper portions 96, so that the displacement of the first fitting 40 in the moving direction of the slider 30 can be further restricted, and the stability of the first fitting 40 can be improved. The body 91 and the stopper 96 may be of an integral structure or a separate structure. When the body 91 and the limiting portion 96 are of an integrated structure, the body 91 and the limiting portion 96 can be prepared through one process, and for convenience of understanding, different names are given to the body 91 and the limiting portion 96 by people. When the body 91 and the limiting portion 96 are of a split structure, the body 91 and the limiting portion 96 can be formed separately and then assembled together in various ways. In the present embodiment, the fitting relationship between the main body 91 and the stopper portion 96 is not limited.
Alternatively, the two stopper portions 96 may be equal or different in size in the arrangement direction of the two rotating shafts 20.
Referring to fig. 22 and fig. 32 again, in the present embodiment, a first sliding portion 39 is disposed on a side of the sliding member 30 close to the body 91, a second sliding portion 97 is disposed on the body 91, and the first sliding portion 39 and the second sliding portion 97 are engaged with each other to enable the sliding member 30 to slide along the axial direction D of the rotating shaft 20.
The side of the slider 30 close to the body 91 may be provided with the first sliding portion 39, and it is also understood that the side of the slider 30 facing away from the guide rail 50 is provided with the first sliding portion 39. The second sliding portion 97 may be correspondingly disposed on the body 91, and the extending directions of the first sliding portion 39 and the second sliding portion 97 may be parallel to the moving direction of the sliding member 30, so that the sliding member 30 can be moved along the axial direction D of the rotating shaft 20 by the guiding movement effect of the first sliding portion 39 and the second sliding portion 97 which are mutually matched. The main body 91 and the second sliding portion 97 may be formed in an integral structure or in a separate structure. When the body 91 and the second sliding portion 97 are of an integrated structure, the body 91 and the second sliding portion 97 can be prepared through one process, and for convenience of understanding, different names are given to the body 91 and the second sliding portion 97 by people. When the body 91 and the second sliding portion 97 are of a split structure, the body 91 and the second sliding portion 97 can be formed separately and then assembled together in various ways. In the present embodiment, the fitting relationship between the main body 91 and the second sliding portion 97 is not limited.
Optionally, the first sliding portion 39 includes a sliding groove or a slider. When the first sliding portion 39 is a sliding groove, the second sliding portion 97 is a sliding block. When the first sliding portion 39 is a slider, the second sliding portion 97 is a sliding groove. Further alternatively, when the first sliding portion 39 is a sliding groove, the second sliding portion 97 is a slider. In this embodiment, the first groove 36 and the second groove 38 can be used as sliding grooves, so that the sliding block can be guided to move the sliding member 30 by only protruding the sliding block on the body 91. In addition, the slot wall of the sliding slot can also limit the sliding block in the arrangement direction of the two rotating shafts 20, so as to prevent the sliding part 30 from moving along the non-moving direction when moving.
