Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In order to solve the above problems in the related art, embodiments of the present disclosure provide a folding structure and an electronic device.
FIG. 1 is a schematic diagram illustrating a folded configuration according to an exemplary embodiment.
As shown in fig. 1, the folding structure 100 of the embodiment of the present disclosure includes: the rotating member 10, the synchronizing bar 20, the cam 30, the rotating shaft 40, the base frame 50, the elastic member 60, and the damper 70. The rotating member 10 is rotatable about a rotating shaft 40.
The synchronizing bar 20 is mounted on the rotating shaft 40, and the synchronizing bar 20 includes a first engaging part 201. The cam 30 is mounted on the rotating shaft 40, and the cam 30 includes a second fitting part 301 capable of fitting with the first fitting part 201, and the second fitting part 301 includes a protrusion capable of fitting with the first fitting part 201. At least one of the first engaging member 201 and the second engaging member 301 includes an inclined surface inclined with respect to the axial direction of the rotating shaft 40, and the first engaging member 201 and the second engaging member 301 are relatively slidable along the inclined surface with the rotation of the rotating member 10, and the first engaging member 201 and the second engaging member 301 are relatively slidable in the axial direction of the rotating shaft 40.
Specifically, in the embodiment shown in fig. 1, the rotating member 10 includes a first rotating member 102 and a second rotating member 103. The synchronizing bar 20 includes a first synchronizing bar 202 and a second synchronizing bar 203. The first synchronizing lever 202 rotates in synchronization with the first rotating member 102, and the second synchronizing lever 203 rotates in synchronization with the second rotating member 103.
The cam 30 includes a first cam 302 and a second cam 303. Rotating shaft 40 includes a first rotating shaft 402 and a second rotating shaft 403. It will be appreciated that in the disclosed embodiment, the same components in the folded structure 100 are symmetrically distributed on the base frame 50.
Further, the rotating member 10 is mounted on a first end of the base frame 50, and the rotating member 10 can rotate relative to the base frame 50, for example, the first rotating member 102 and the second rotating member 103 are symmetrically mounted on the first end of the base frame 50, and the synchronizing bar 20 is mounted on the base frame 50 through the rotating shaft 40. The first synchronizing lever 202 is attached to the first rotating shaft 402, and the first synchronizing lever 202 and the first rotating member 102 rotate synchronously about the first rotating shaft 402. The second synchronizing lever 203 is attached to the second rotating shaft 403, and the second synchronizing lever 203 and the second rotating member 103 rotate synchronously about the second rotating shaft 403.
In the disclosed embodiment, the first end 204 of the synchronization rod 20 is formed with a partial gear structure 2041 (shown in fig. 4), and the first mating member 201 of the synchronization rod 20 is formed at a second end of the synchronization rod 20 opposite to the first end 204. For example, a first partial gear structure 2021 is formed at the first end 204 of the first synchronizing lever 202, a second partial gear structure 2031 is formed at the first end 204 of the second synchronizing lever 203, and the first partial gear structure 2021 and the second partial gear structure 2031 are engaged with each other.
The first partial gear structure 2021 on the first end 204 of the first synchronization lever 202 and the second partial gear structure 2031 on the first end 204 of the second synchronization lever 203 are directly engaged for synchronous rotation by the partial gear structure 2041 formed at the first end 204 of the synchronization lever 20. Therefore, the additional arrangement of a transmission part between the first synchronizing rod 202 and the second synchronizing rod 203 to realize the synchronous rotation of the first synchronizing rod 202 and the second synchronizing rod 203 is avoided. Therefore, in the embodiment of the present disclosure, the precision of the synchronous rotation of the first and second synchronization rods 202 and 203 can be improved by providing the local gear structure 2041 on the first end 204 of the synchronization rod 20, and the occupied space of the base frame 50 can be saved.
In the disclosed embodiment, the folding structure 100 further includes an elastic member 60, the elastic member 60 being disposed axially along the rotation shaft 40 for supporting the second fitting member 301 of the cam 30, for example, the elastic member 60 being disposed between a second end of the cam 30 opposite to the first end of the base frame 50. The cam 30 and the elastic member 60 are attached to the rotating shaft 40.
In the embodiment shown in fig. 1, the elastic member 60 includes a first elastic member 602 and a second elastic member 603. The first cam 302 and the first elastic member 602 are attached to the first rotating shaft 402, and the second cam 303 and the second elastic member 603 are attached to the second rotating shaft 403.
In the embodiment of the present disclosure, when the first engaging part 201 of the synchronizing lever 20 and the second engaging part 301 of the cam 30 perform relative sliding on the inclined surface, since the cam 30 is pressed by the inclined surface of the synchronizing lever 20, the elastic member 60 is compressed and deformed by the pressing force of the cam 30. When the first engagement part 201 of the synchronizing lever 20 and the second engagement part 301 of the cam 30 are relatively slid on the inclined surface in the inclination increasing direction of the inclined surface, the deformation stroke of the elastic member 60 is gradually reduced.
Further, in order to fix the elastic member 60 between the cam 30 and a second end of the base frame 50 opposite to the first end, the folding structure 100 in the embodiment of the present disclosure further includes a blocking plate 70, and a limiting hole 701 is provided on the blocking plate 70, and the limiting hole 701 is used for fixing the rotating shaft 40. In the embodiment of the present disclosure, when the first engaging member 201 of the synchronizing rod 20 and the second engaging member 301 of the cam 30 slide relatively on the inclined surface, the elastic member 60 generates a corresponding deformation stroke between the baffle 70 and the synchronizing rod 20, and thus generates a corresponding resilient force on the inclined surface.
In the embodiment of the present disclosure, the first engaging member 201 of the synchronization rod 20 and/or the second engaging member 301 of the cam 30 are provided with an inclined surface inclined with respect to the rotating shaft 40, so that when the first engaging member 201 and the second engaging member 301 slide on the inclined surface relatively, the deformation stroke of the elastic member 60 is changed to generate a corresponding resilient force on the inclined surface. The component force of the resilience force of the elastic component 60 along the inclined surface direction on the inclined surface is offset with the component force along the inclined surface direction on the inclined surface when the first matching component 201 and the second matching component 301 perform reverse relative sliding, so that the rotating component 10 achieves the hovering purpose in the rotating process. The design of the inclined surface on the first matching part 201 and/or the second matching part 301 and the resilience provided by the elastic part 60 can further improve the hovering effect of the folding structure 100 during folding.
Further, FIG. 2 is a perspective view of the folded state of FIG. 1 in a cross-sectional view taken along the direction A-A' according to an exemplary embodiment. FIG. 3 is a folded view of FIG. 1 in cross-section taken along the direction B-B' according to an exemplary embodiment. FIG. 4 is a side view of a synchronization rod shown in accordance with an exemplary embodiment.
As shown in fig. 2, an arc-shaped groove 101 is formed on the rotating member 10, an arc-shaped sliding rail 501 is formed at the first end of the base frame 50, the rotating member 10 and the base frame 50 are connected with the arc-shaped sliding rail 501 through the arc-shaped groove 101, and the arc-shaped sliding rail 501 can slide in the arc-shaped groove 101.
Specifically, in the embodiment of the present disclosure, a first arc-shaped groove 1011 is formed on the first rotating member 102, and a second arc-shaped groove 1012 is formed on the second rotating member 103. A first arcuate slide rail 5011 and a second arcuate slide rail 5012 are formed on the first end of the base frame 50, wherein the first arcuate slide rail 5011 is slidable within the first arcuate recess 1011 and the second arcuate slide rail 5012 is slidable within the second arcuate recess 1012 to allow the first rotating member 102 and the second rotating member 103 to rotate within an arc.
The radian of the arc-shaped groove 101 and the arc-shaped sliding rail 501 are matched, the arc can be semicircular, and the radians of the arc-shaped groove 101 and the arc-shaped sliding rail 501 can be set based on actual needs, for example, the radian can be 0-45 degrees, and no specific limitation is made here.
In the embodiment of the present disclosure, the arc-shaped sliding rail 501 may have a certain toughness, such as a metal material, so as to ensure that the arc-shaped sliding rail 501 slides in the arc-shaped groove 101 and improve the durability of the arc-shaped sliding rail 501.
Further, as shown in fig. 3 and 4, the rotating member 10 is provided with a sliding slot 104, a sliding lock 2042 disposed opposite to the partial gear structure 2041 is formed at the first end 204 of the synchronization rod 20, and the sliding lock 2042 of the synchronization rod 20 can slide in the sliding slot 104 of the rotating member 10. For example, in the embodiment of the present disclosure, when the rotating member 10 rotates around the rotating shaft 40, the arc-shaped sliding rail 501 on the base frame 50 slides in the arc-shaped groove 101 of the rotating member 10. At the same time, slide lock 2042 slides in slide groove 104 of rotating member 10. Further, the first partial gear structure 2021 of the first synchronizing lever 202 and the second partial gear structure 2031 of the second synchronizing lever 203 are engaged with each other to realize synchronous rotation about the rotation shaft 40.
As shown in fig. 4, in the embodiment of the present disclosure, the first fitting member 201 includes a first inclined surface 2011 and a second inclined surface 2012, and an angle between the first inclined surface 2011 and the axial direction of the rotating shaft 40 is greater than an angle between the second inclined surface 2012 and the axial direction of the rotating shaft 40. For example, the first engaging member 201 of the synchronizing lever 20 is formed in a boss shape, a top surface of the boss shape constitutes the first inclined surface 2011, and a left side surface of the boss shape constitutes the second inclined surface 2012. When the first engaging member 201 and the second engaging member 301 slide relative to each other along the inclined surfaces, the first inclined surface 2011 may enable the cam 30 to move along the axial direction of the rotating shaft 40, and the second inclined surface 2012 may facilitate the relative sliding of the first engaging member 201 and the second engaging member 301. The second fitting part 301 of the cam 30 is formed in a convex shape, and the top surface of the convex shape is not particularly limited in the embodiment of the present disclosure.
Preferably, the convex-shaped top surface of the cam 30 is fitted with the convex-shaped top surface of the synchronizing bar 20. The parallel design of the top surfaces of the boss shape and the protrusion shape makes it easier to slide the first mating part 201 and the second mating part 301 relatively, and thus makes the folding structure 100 more convenient to fold.
In the disclosed embodiment, the inclination of the inclined surface to the axial direction of the rotating shaft 40 is set based on the folding direction of the folding structure 100. In the embodiment of the present disclosure, along the folding direction of the folding structure 100, the inclination of the inclined surface increases with the axial direction of the rotating shaft 40, so as to ensure that the deformation stroke of the elastic member 60 increases gradually as the rotation radian of the rotating member 10 increases, and further, the resilience provided by the elastic member 60 increases correspondingly. The folding structure 100 can realize the hovering purpose during the folding process by the design of the inclination of the inclined plane and the axial direction of the rotating shaft 40.
In the embodiment of the present disclosure, the folding structure 100 is suspended during the folding process by setting the inclination of the inclined plane to the axial direction of the rotating shaft 40, and by changing the component force of the resilience of the elastic member 60 to the force applied to the inclined plane in two directions.
Specifically, fig. 5 is a schematic diagram illustrating that the elastic force of the elastic member is applied to the inclined surface according to an exemplary embodiment of the present disclosure.
As shown in fig. 5, when the first engaging member 201 of the synchronizing lever 20 and the second engaging member 301 of the cam 30 slide relative to each other on the first inclined surface 2011 to the position S, the elastic force F provided by the elastic member 60 may be divided into F1 and F2 at the position S of the first inclined surface 2011. Where F1 is a component force of the spring force F in the direction along the first inclined surface 2011, F2 is a component force of the spring force F in the direction perpendicular to the first inclined surface 2011, and F1 moves the position S in a direction in which the inclination of the first inclined surface 2011 with respect to the axial direction of the rotating shaft 40 decreases. When the first engaging member 201 of the synchronization rod 20 and the second engaging member 301 of the cam 30 slide on the first inclined surface 2011 in opposite directions, a component force equal to F1 in magnitude and opposite in direction is generated, so that the relative position of the first engaging member 201 of the synchronization rod 20 and the second engaging member 301 of the cam 30 on the first inclined surface 2011 stays at the position S, and the folding structure 100 is suspended during the folding process.
Further, as in the embodiment shown in fig. 4, the synchronization rod 20 includes 3 first engaging parts 201, and it should be noted that the synchronization rod 20 may include a plurality of first engaging parts 201, for example, 3, 4, 5 or more. The cam 30 includes a plurality of second engaging parts 301 corresponding to the plurality of first engaging parts 201, and in the embodiment of the present disclosure, the number of the second engaging parts 301 of the cam 30 may not correspond to the number of the first engaging parts 201 of the synchronizing bar 20, and is not particularly limited herein. When the number of the second fitting parts 301 is corresponding to the number of the first fitting parts 201, there is an effect that the relative force of the synchronizing bar 20 is uniform.
It should be noted that the inclination of the inclined surface in the embodiment of the present disclosure is determined by comprehensive calculation for the specific application of the folded structure 100. For example, when the folding structure 100 is applied to a folding screen mobile phone, the inclination of the inclined plane is determined by comprehensively calculating the gravity of the whole mobile phone and the elastic force of the display screen itself.
FIG. 6 is a schematic view of a baffle shown according to an exemplary embodiment.
In the folding structure 100 of the disclosed embodiment, the baffle 70 is detachably connected to the base frame 50. As shown in fig. 6, the stopper 70 is provided with a stopper hole 71 and a stopper portion 72, and the stopper hole 71 is provided at a position facing the rotation shaft 40. The base frame 50 is provided with a fastening structure 502 (as shown in fig. 1) engaged with the limiting portion 72, and the baffle 70 is detachably connected to the base frame 50 through the engagement of the limiting portion 72 and the fastening structure 502. It is to be understood that the disclosed embodiment is merely illustrative of one manner of removably attaching the baffle 70 to the base frame 50 and is not limited thereto.
Specifically, in the folding structure 100 according to the embodiment of the present disclosure, a groove (not shown) is provided on the rotating shaft 40, and the position of the groove is preferably at the connecting end of the rotating shaft 40 and the base frame 50. The limiting portion 72 of the baffle 70 is matched with the fastening structure 502 of the base frame 50, and the hole wall of the limiting hole 71 is disposed in the groove of the rotating shaft 40, so that the rotating shaft 40 is fixed in the limiting hole 71.
Fig. 7 is a schematic diagram illustrating a folded configuration according to an exemplary embodiment.
As shown in fig. 7, the embodiment of the present disclosure provides a folding structure 100, and the folding structure 100 omits the baffle 70 from the folding structure 100 of the previous embodiment, and instead provides a clamp 503 on the base frame 50, and the rotating shaft 40 is provided on the clamp 503. Specifically, the clamp 503 according to the embodiment of the present disclosure is formed in a resilient structure having an opening at an upper end, and the opening diameter of the upper end is smaller than the diameter of the rotating shaft 40, so as to ensure that the rotating shaft 40 can enter the clamp 503 from an upper port of the clamp 503. A groove (not shown) is provided on the end of the shaft 40 to which the yoke 503 is attached, and the yoke 503 is fitted into the groove of the shaft 40 so that the shaft 40 is restrained within the yoke 503.
In another embodiment, a shielding portion (not shown) may be provided instead of the groove at the end of the rotating shaft 40 connected to the yoke 503. The shielding portion may be a shielding piece, and the sectional area of the shielding piece is larger than that of the clamp 503, so that the shielding portion prevents the rotating shaft 40 from being separated from the clamp 503, and the purpose of fixing the rotating shaft 40 and the clamp 503 is achieved.
The clip 503 in the folding structure 100 of the embodiment of the present disclosure may also be a non-elastic clip 503 with a snap design at its upper port, and after the rotating shaft 40 is snapped into the clip 503, the rotating shaft 40 is fixed by the snap design at its upper port.
As can be seen from the above, the folding structure in the embodiment of the present disclosure has a simple overall structure, can achieve the hovering purpose during the folding process, and can be disassembled from each other, so that the folding structure is more flexible in the assembling manner. During the use of the folding structure, the corresponding parts can be replaced and maintained more conveniently after part of the assembly is damaged. In the embodiment of the disclosure, the design of the baffle is adopted, and the components are tightly connected and fixed with each other through the baffle, so that the stability of the integral folding structure is improved. Meanwhile, the baffle and the base frame are detachably assembled, so that the overall assembling and maintaining efficiency is improved.
Based on the same concept, the embodiment of the present disclosure further provides an electronic device, which includes a display screen and a folding structure. The folding structure is the folding structure in the embodiment of the disclosure, wherein the display screen is mounted on a rotating part of the folding structure, and the display screen can be folded along with the rotation of the rotating part.
The electronic device in the embodiment of the present disclosure may be a smartphone, a tablet computer, a wearable device, or the like. For example, the electronic device may be a folding screen mobile phone, a folding screen computer, or the like.
The display screen of the electronic device of the embodiment of the present disclosure may be a flexible foldable display screen, and may also be a rigid display screen. For example, in a tablet computer, the display screen is a rigid display screen, and only one of the relevant components of the folding structure in the embodiment of the present disclosure is needed. When the tablet personal computer is used, the display screen of the tablet personal computer needs to be properly adjusted, and the connecting component and the display screen rotate synchronously in the adjusting process. When the display screen is adjusted to a proper position, after the acting force of a human hand on the display screen is relieved, the first matching part of the synchronizing rod and the second matching part of the cam are relatively static at the proper position of the inclined surface under the action of the elastic force of the elastic part of the folding structure, and then the display screen is suspended at the proper position.
In an embodiment of the present disclosure, the display screen includes a folding area, the folding area is provided with a plurality of folding mechanisms, and the plurality of folding mechanisms are symmetrically arranged along an axis midpoint of the display screen. For another example, in a folding screen mobile phone, the display screen is a flexible foldable display screen, the number of the related components of the folding structure in the embodiment of the present disclosure is two, and the folding structure is symmetrically distributed on the base frame along the axial center. The two rotating parts are respectively used for connecting two opposite sides of the flexible foldable display screen to enable the flexible foldable display screen to be folded along the length direction or the width direction, and the two synchronizing rods are meshed with each other through local gear characteristics on the first ends of the two synchronizing rods and are synchronously linked with the rotating parts. When the flexible foldable display screen is folded to a proper position, the component force of the elastic force provided by the elastic component of the folding structure on the inclined plane offsets with the self gravity of the mobile phone and the component force of the elastic force of the flexible foldable display screen on the inclined plane, so that the flexible foldable display screen is folded to the proper position.
It is understood that "a plurality" in this disclosure means two or more, and other words are analogous. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. The singular forms "a", "an", and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
It will be further understood that the terms "first," "second," and the like are used to describe various information and that such information should not be limited by these terms. These terms are only used to distinguish one type of information from another and do not denote a particular order or importance.
