Background

The electronic device is a terminal device indispensable in people's calendar life. In order to improve portability of electronic devices, most electronic devices have a folding function, so that the volume of the electronic device is reduced, and the electronic device is convenient to carry.

In order to avoid the situation that the electronic equipment is damaged due to the fact that stress is high in the folding process, the damping component is arranged in the electronic equipment so as to offset the external force applied to the electronic equipment by a user, and therefore the risk that the electronic equipment is damaged is reduced.

However, in the conventional damping assembly, a spring is generally used as an elastic component, and the magnitude of the elastic force generated by the spring depends on the thickness of the spring, so that the electronic device is not beneficial to thinning, and the thinning of the electronic device is affected.

The first damping portion is connected with the first member. The second damping portion is rotatable in synchronization with the second member, and the second damping portion is capable of abutting the first damping portion. The plurality of elastic sheets are sequentially stacked, gaps are reserved between partial areas of two adjacent elastic sheets, and the partial areas of the two adjacent elastic sheets are mutually abutted. In the process of relative rotation of the second component and the first component, the second damping part and the first damping part move relatively and squeeze the elastic pieces, and the elastic pieces enable the second damping part and the first damping part to be in mutual abutting connection so as to generate damping force.

According to the rotating mechanism provided by the first aspect of the application, during the process of rotating the second component relative to the first component, the second damping part and the second component synchronously rotate, and the second damping part and the first damping part relatively move. Meanwhile, the elastic sheets are extruded to generate elastic force, so that the second damping part and the first damping part are mutually abutted to generate damping force. Because the elastic sheets are sequentially stacked, and the elastic sheets are of plate-shaped structures, larger elastic force can be generated when the elastic sheets deform. And the elastic force can be improved by increasing the thickness dimension of the elastic sheet, so that the width dimension parallel to the direction of the elastic sheet can be reduced, thereby being beneficial to the light and thin electronic equipment.

In this way, the geometric centers of two adjacent elastic sheets are mutually abutted, and the edges of two elastic sheets in one group are mutually abutted, namely each elastic sheet is in a curved surface shape.

In this way, since the elastic sheet is of a strip structure, and the first direction and the second direction are perpendicular to the thickness direction of the first component or the second component, the size of the elastic sheet along the thickness direction of the first component or the second component is reduced, and the thickness of the first component or the second component can be reduced.

For example, the electronic device may be a folding screen cell phone, a notebook computer, or the like. The mobile phone with the folding screen can be a mobile phone with an external folding display screen or an internal folding display screen. The embodiment will be described by taking an electronic device as an example of a mobile phone with an external folding display screen.

Specifically, referring to fig. 1, fig. 1 is a perspective view of an electronic device 01 according to an embodiment of the present application. The electronic device 01 may comprise a folding screen 10 and a support means 20. It is to be understood that the figures only schematically show some components of the electronic device 01, the actual shape, the actual size, the actual position and the actual configuration of which are not limited by the figures.

The folding screen 10 includes a first portion 11, a second portion 12, and a third portion 13, the third portion 13 being disposed between the first portion 11 and the second portion 12. When the folding screen 10 is folded, the third portion 13 is folded and the first portion 11 is disposed opposite the second portion 12. At least the third portion 13 of the folding screen 10 is made of a flexible material, and the first portion 11 and the second portion 12 may be made of a flexible material, may be made of a rigid material, or may be made of a flexible material, and may be made of a rigid material. Therefore, the present application is not particularly limited thereto.

The folding screen 10 may be an organic light-emitting diode (OLED) display screen, an active-atrix organic light-eitting diode (AOLED) display screen, a mini-led (ini organic light-eitting diode) display screen, a micro-led (icro organic light-eitting diode) display screen, a micro-organic led (icro organic light-eitting diode) display screen, a quantum dot led (quantu dot light eitting diode, QLED) display screen, a liquid crystal display screen (liquid crystal display, LCD) or the like.

The folding screen 10 is supported on a support device 20. Referring to fig. 2, fig. 2 is a front view of an electronic device 01 according to an embodiment of the application. The support device 20 may include a first housing 21, a second housing 22, and a rotation mechanism 23, the rotation mechanism 23 being connected between the first housing 21 and the second housing 22. The first casing 21 has a first contact surface M1 thereon, and the first portion 11 of the folding screen 10 is supported by and contacts the first contact surface M1. The second housing 22 has a second contact surface M2 thereon, and the second portion 12 of the folding screen 10 is supported by and contacts the second contact surface M2. The rotating mechanism 23 has a third contact surface M3, and the third portion 13 of the folding screen 10 is supported and attached to the third contact surface M3. The first housing 21 and the second housing 22 are rotatably connected by a rotation mechanism 23 to enable the electronic apparatus 01 to rotate between an extended position and a collapsed position.

When the electronic device 01 is in the deployed position, please continue to refer to fig. 1 and 2, and the electronic devices shown in fig. 1 and 2 are both in the deployed state. The first bonding surface M1, the second bonding surface M2, and the third bonding surface M3 are in the same plane, so that the folding screen 10 is completely unfolded, and the flatness of the folding screen 10 can be ensured. In this state, the large-screen display of the electronic device 01 can be realized, and better use experience can be brought to the user. For example, when a user views a movie using the electronic device 01, the electronic device 01 may be expanded to use a large screen for viewing, thereby achieving a better viewing experience.

Referring to fig. 3, fig. 3 is a front view of an electronic device 01 in a folded position according to an embodiment of the present application when a terminal of the folding screen 10 is in the folded position. The first portion 11 of the folding screen 10 is opposite to the second portion 12, i.e. the first portion 11 and the second portion 12 are respectively facing in opposite directions, the third portion 13 of the folding screen 10 is in a folded state, and the supporting means 20 is located between the first portion 11 and the second portion 12. At this time, the electronic apparatus 01 displays an image using only the first portion 11 or the second portion 12 of the folding screen 10, i.e., the user can perform a one-handed operation using a small screen. For example, when the user sits on the public transportation means, since the user can hold the electronic device 01 with only one hand, the electronic device 01 can be folded at this time to reduce the width of the electronic device 01, thereby performing one-hand operation, which is advantageous for further improving the user experience.

In this way, the usage status of the electronic device 01 can be increased to be suitable for different usage scenarios. The user can freely select the use state of the terminal according to different use scenes, and the user can obtain better use experience.

Based on this, referring to fig. 4, fig. 4 is a perspective view of a rotation mechanism 23 of an electronic device 01 according to an embodiment of the application, the rotation mechanism 23 may include a center sill 110 and door panels 210, and the door panels 210 are disposed on both sides of the center sill 110 along the length direction. Wherein, the middle beam 110 may form the first part 100, the door panel 210 may form the second part 200, and the first part 100 and the second part 200 may rotate relatively. It can be appreciated that, when the electronic device 01 provided in the embodiment of the present application is another device, the first component 100 and the second component 200 may also be in other structural forms.

Referring to fig. 5, fig. 5 is a connection structure diagram of a rotating mechanism 23 of an electronic device 01 according to the present application. When the electronic device 01 is a mobile phone with an external folding display screen, the rotating mechanism 23 may further include a slider 400, and the center sill 110 (i.e., the first member 100) and the door panel 210 (i.e., the second member 200) are connected by the slider 400. The two sides of the middle beam 110 along the length direction are respectively provided with a door plate 210 and a sliding block 400, at least one sliding block 400 is arranged between the door plate 210 and the middle beam 110, a first end of the sliding block 400 is rotationally connected with the middle beam 110, a second end of the sliding block 400 is connected with an adjacent door plate 210, and the first shell 21 and the second shell 22 are respectively and fixedly connected with the adjacent door plate 210, so that the door plate 210 drives the first shell 21 and the second shell 22 to rotate between a folding position and an unfolding position.

Specifically, referring to fig. 6 and 7, fig. 6 is an enlarged view of a region a of the rotating mechanism 23 provided in fig. 5, and fig. 7 is an exploded view of the rotating mechanism 23 provided in fig. 6. The middle beam 110 may include a beam body 112 and a cover plate 113, where the beam body 112 is provided with an arc-shaped groove 111, an axis of the arc-shaped groove 111 is parallel to a length direction of the middle beam 110, and a first end of the slider 400 extends into the arc-shaped groove 111, so that the first end of the slider 400 can slide along a circumferential direction of the arc-shaped groove 111, that is, the slider 400 can rotate around the axis of the arc-shaped groove 111. The cover plate 113 is fastened to the beam body 112, and the cover plate 113 is fixedly connected to the beam body 112, for example, by a screw or a clip. So that the slider 400 is connected with the center sill 110, and the slider 400 can only rotate along the arc-shaped groove 111, which is beneficial to improving the reliability of the overall structure.

Wherein, when the electronic device 01 is in the unfolded position, the first end of the sliding block 400 is completely positioned in the arc-shaped groove 111; when the electronic device 01 rotates from the unfolded position to the folded position, the first end of the slider 400 slides along the arc-shaped groove 111; when the electronic device 01 is rotated to the folded position, a portion of the first end of the slider 400 slides out of the arc-shaped groove 111. At this time, since a portion of the first end of the slider 400 slides out of the arc-shaped groove 111, the length of the portion of the slider 400 outside the arc-shaped groove 111 is increased.

In this way, during the rotation of the electronic device 01 from the extended position to the folded position, the first housing 21 and the corresponding door panel 210 or the second housing 22 and the corresponding door panel 210 move in a direction away from the center sill 110. Since the folding screen 10 is fixed to the first housing 21 and the second housing 22, the first housing 21 and the first portion 11 of the folding screen 10 and the second housing 22 and the second portion 12 of the folding screen 10 are relatively moved, and thus the folding screen 10 is damaged and fails.

Therefore, to avoid damage to the folding screen 10, the sliding blocks 400 and the door plates 210 are slidably connected, and during the process of rotating the electronic device 01 from the unfolded position to the folded position, the sliding blocks 400 slide relative to the corresponding door plates 210 (i.e., the door plates 210 slidably connected with the sliding blocks 400) in a direction approaching the door plates 210, i.e., the door plates 210 slide relative to the corresponding sliding blocks 400 in a direction approaching the middle beam 110, so that the first housing 21 and the corresponding door plates 210 and the second housing 22 and the corresponding door plates 210 are prevented from moving away from the middle beam 110 during the rotating process of the electronic device 01, and thus, relative movement between the first housing 21 and the second housing 22 and the first portion 11 and the second portion 12 of the folding screen 10 is prevented, so as to protect the folding screen 10.

Specifically, referring to fig. 6 and 7, the door 210 may be provided with a sliding groove 211, and the second end of the sliding block 400 extends into the sliding groove 211 to achieve sliding connection between the sliding block 400 and the door 210. And the sliding direction of the slider 400 is perpendicular to the rotation axis of the slider 400. Under this structure, in the process that the first end of the slider 400 slides out of the arc-shaped groove 111 on the center sill 110, the second end of the slider 400 can slide into the sliding groove 211 on the door panel 210, so that the distance between the door panel 210 and the center sill 110 is kept unchanged when the electronic device 01 is located at the folded position and the unfolded position, that is, the distance between the first and second housings 21 and 22 and the center sill 110 is kept unchanged, so as to avoid the relative movement between the first housing 21 and the first portion 11 of the folding screen 10 and between the second housing 22 and the second portion 12 of the folding screen 10.

In addition, in order to improve the use feel of the electronic device 01 when rotating between the folded position and the unfolded position. The rotation mechanism 23 may further include a damper assembly 300, where the damper assembly 300 is disposed between the first member 100 and the second member 200 shown in fig. 4, referring to fig. 8 and 9, fig. 8 is an exploded view of the damper assembly 300 according to the embodiment of the present application, and fig. 9 is an assembled view of the damper assembly 300 according to fig. 8.

The damper assembly 300 may include a first damper part 300a, a second damper part 300b, and an elastic member 300c. The first damping portion 300a is connected to the first member 100 (i.e., the center sill 110 in fig. 8), the second damping portion 300b is connected to the second member 200 (i.e., indirectly connected to the door panel 210 via the slider 400 in fig. 8), the second damping portion 300b can rotate synchronously with the second member 200, and the second damping portion 300b can also abut against the first damping portion 300 a. During the relative rotation of the second member 200 and the first member 100, the second damping portion 300b and the first damping portion 300a move relatively and abut against each other, and the elastic member 300c is pressed, so that the elastic force of the elastic member 300c generates a damping force between the second damping portion 300b and the first damping portion 300 a.

Specifically, in this embodiment, the electronic device 01 is a mobile phone with an external folding display screen, and in this scenario, please continue to refer to fig. 8 and 9. The first damping portion 300a is an abutment inclined surface 310, and the abutment inclined surface 310 is formed at the edge of the center sill 110 near the slider 400. The second damping portion 300b is a supporting frame 330, the supporting frame 330 is connected with the slider 400 and rotates synchronously, and the elastic member 300c abuts between the supporting frame 330 and the slider 400. In the process of synchronously rotating the support frame 330 and the slider 400, the support frame 330 can abut against the abutment inclined plane 310 and slide along the abutment inclined plane 310, so that the support frame 330 and the slider 400 slide relatively and press the elastic member 300c.

Thus, when the electronic device 01 rotates between the extended position and the folded position, the supporting frame 330 abuts against the abutment inclined plane 310 and slides along the abutment inclined plane 310, so that the supporting frame 330 slides relative to the slider 400, thereby pressing the elastic member 300c, compressing the elastic member 300c, and generating an elastic force. Accordingly, the elastic member 300c applies a reaction force to the supporting bracket 330, thereby forming a damping force between the supporting bracket 330 and the abutment slope 310. When the user rotates the electronic equipment 01, the damping effect can be achieved, so that the using hand feeling of the user is improved. And moreover, the situation that the equipment is damaged due to overlarge force of a user is avoided.

As an example, referring to fig. 8 and 9, the elastic member 300c may also employ a spring 350, that is, the spring 350 abuts between the slider 400 and the supporting frame 330, and when the slider 400 and the middle beam 110 rotate relatively, the supporting frame 330 abuts against the abutment inclined plane 310 and slides along the abutment inclined plane 310, and simultaneously the supporting frame 330 and the slider 400 slide relatively and compress the spring 350, so that an elastic force generated by compression of the spring 350 acts on the supporting frame 330, and a damping force is formed between the supporting frame 330 and the abutment inclined plane 310.

Wherein the spring 350 is arranged in a direction parallel to the folding screen 10 shown in fig. 1 and 2. Specifically, the damping assembly 300, which is disposed between the first housing 21 and the center sill 110 shown in fig. 2, has the axis of the spring 350 parallel to the first portion 11 of the folding screen 10. The damper assembly 300, which is disposed between the second housing 22 and the center sill 110 shown in fig. 2, has the axis of the spring 350 parallel to the second portion 12 of the folding screen 10.

However, the spring 350 provides a large damping force, and the spring 350 having a large diameter is required, which causes an increase in the size of the electronic apparatus 01 in the thickness direction, and is disadvantageous in terms of the slimness and thinness of the electronic apparatus 01.

Referring to fig. 10 and 11, fig. 10 is a structural diagram of another elastic member 300c according to the present application, and fig. 11 is a structural diagram of the elastic member 300c provided in fig. 10 disposed between a slider 400 and a supporting frame 330. The elastic member 300c includes a plurality of elastic pieces 360, the plurality of elastic pieces 360 are sequentially stacked, a gap is formed between partial areas of two adjacent elastic pieces 360, and the partial areas of two adjacent elastic pieces 360 are abutted against each other.

In this way, the disk spring 350 is formed by the plurality of spring pieces 360, and the disk spring 350 has the characteristics of high rigidity, high load bearing with small deformation, and the like. In addition, on the premise of not changing the size of the elastic sheet 360, when a larger elastic force is needed, only the number of the elastic sheets 360 is needed to be increased. Therefore, the elastic pieces 360 with smaller size can be selected, and the number of the elastic pieces 360 is increased to provide the elastic force capable of meeting the requirement of the damping assembly 300, so that the thickness of the electronic device 01 is not increased, which is beneficial to the thinning of the electronic device 01.

Wherein, the elastic pieces 360 may include a plurality of groups of elastic pieces 360, each group of elastic pieces 360 includes two elastic pieces 360, a gap distance between the two elastic pieces 360 in each group of elastic pieces 360 gradually decreases along a direction of a geometric center of the elastic piece 360 pointing to an edge of the elastic piece 360, and at least a part of the edges of the two elastic pieces 360 in each group of elastic pieces 360 are mutually abutted.

For example, referring to fig. 12, fig. 12 is a front view of the elastic member 300c provided in fig. 10, and fig. 13 is a structural diagram of the elastic member 300c provided in fig. 10 disposed in the rotation mechanism 23. The elastic sheet 360 may have a strip-shaped structure, and the length direction of the elastic sheet 360 is a first direction, i.e., a Y direction in fig. 12, and the stacking direction of the plurality of elastic sheets 360 is a second direction, i.e., an X direction in fig. 12, where the first direction is perpendicular to the second direction. The second member 200 formed by the door panel 210 has a plate-like structure, and the first direction and the second direction are perpendicular to the thickness direction of the door panel 210, i.e., the Z direction in fig. 13.

Specifically, the two elastic pieces 360 in each set of elastic pieces 360 may include a first elastic piece 360a and a second elastic piece 360b, a gap between the first elastic piece 360a and the second elastic piece 360b gradually decreases from a middle portion of the first elastic piece 360a to two ends along the first direction, and the two ends of the first elastic piece 360a and the second elastic piece 360b abut against each other along the first direction.

In this way, the elastic pieces 360 are all of elongated structures, the first direction Y is the length direction of the elastic pieces 360, and the second direction X is the thickness direction of the elastic pieces 360, so the thickness direction Z of the door panel 210 is the width direction of the elastic pieces 360. It can be seen that the shape of the spring plate 360 is approximately rectangular, and the width dimension thereof is smaller than the length dimension thereof. Therefore, the strip-shaped elastic sheet 360 has a smaller width, which is beneficial to reducing the thickness of the door plate 210, thereby being beneficial to reducing the thickness of the electronic device 01.

It can be appreciated that, in the elastic sheet 360 of the strip structure, the middle parts of the two adjacent elastic sheets 360 are abutted against each other in the two adjacent elastic sheets 360, so as to form a plurality of elastic sheets 360 which are sequentially stacked. When the plurality of elastic pieces 360 of the elongated structure are pressed, each elastic piece 360 is deformed until being pressed into a flat plate shape to store energy.

Alternatively, the elastic pieces 360 may also adopt a circular structure, that is, the distance between the two elastic pieces 360 in each group of elastic pieces 360 gradually decreases from the center of a circle to the direction of the edge, that is, each elastic piece 360 forms a structure similar to a cone, so that the edges of the two elastic pieces 360 are abutted against each other. With this structure, the centers of the adjacent two groups of elastic sheets 360 are abutted against each other, so that the belleville spring 350 structure can be formed. When the plurality of elastic pieces 360 are compressed, each elastic piece 360 is deformed until the elastic pieces 360 are pressed into a flat plate shape to store energy. When the compressive force is removed, the energy is released and the spring 360 springs back to the original cone configuration.

In addition, the arrangement manner of the plurality of elastic pieces 360 is not unique, for example, the plurality of elastic pieces 360 may be arranged in a positive-to-negative sequence as shown in fig. 12 and 13, and it is understood that the positive-to-negative sequence refers to that the concave surface of one elastic piece 360 faces the left direction in the drawing, and the concave surface of the adjacent other elastic piece 360 faces the right direction in the drawing, that is, the plurality of elastic pieces 360 are stacked in a positive-to-negative sequence.

Alternatively, referring to fig. 14, fig. 14 is a schematic diagram illustrating another arrangement of a plurality of spring plates 360 according to an embodiment of the present application. The plurality of elastic pieces 360 may be sequentially stacked in an irregular arrangement manner, that is, any two adjacent elastic pieces 360 in the plurality of elastic pieces 360 may be disposed in the same direction, for example, concave surfaces of two adjacent elastic pieces 360 in fig. 14 face a right direction in the drawing, and concave surfaces of two adjacent elastic pieces 360 face a left direction in the drawing. It will be appreciated that the irregular arrangement of the plurality of spring plates 360 may be determined according to the use requirements, for example, the amount of damping force required by the device. Therefore, the present application is not particularly limited thereto.

In this way, on the one hand, the elastic force generated when the plurality of elastic sheets 360 are compressed can be improved; on the other hand, when the elastic sheet 360 is processed, the elastic sheet 360 can be produced in batches according to the unified standard, and the elastic sheets 360 with different specifications do not need to be produced according to different equipment, so that the production efficiency is improved, and meanwhile, the production cost is reduced.

The larger the number of stacked elastic pieces 360 is, the larger the elastic force can be generated. Therefore, the elastic pieces 360 with smaller diameters can be adopted, and the elastic pieces 300c formed by the elastic pieces 360 can generate elastic force required by the damping assembly 300 by increasing the number of the elastic pieces 360, so that the size along the thickness direction of the electronic device 01 can be reduced, and the thinning of the electronic device 01 is facilitated.

In some embodiments, referring to fig. 15, fig. 15 is a schematic diagram of another elastic sheet 360 according to an embodiment of the present application, and at least one adjusting hole 361 may be formed in the elastic sheet 360. Through set up regulation hole 361 on shell fragment 360, can adjust the elastic force size that shell fragment 360 produced when taking place the deformation to the elastic force size that a plurality of shell fragments 360 can produce of more accurate regulation of being convenient for.

In addition, in order to avoid the plurality of elastic pieces 360 moving in a plane perpendicular to the second direction (the stacking direction of the plurality of elastic pieces 360), referring to fig. 16, fig. 16 is a block diagram of another elastic piece 360 according to an embodiment of the present application. The damping assembly 300 may further include a limiting shaft 370, where the limiting shaft 370 is disposed along the stacking direction of the plurality of elastic sheets 360, and the limiting shaft 370 sequentially penetrates the plurality of elastic sheets 360. In this way, the elastic sheet 360 can be limited to move along the direction perpendicular to the limiting shaft 370 by the limiting shaft 370, so that the elastic sheet 360 is ensured to be compressed only along the length direction (i.e. the second direction) of the limiting shaft 370, which is beneficial to improving the reliability of the overall structure of the damping assembly 300.

In some embodiments, the limiting shafts 370 may be provided in plurality, and the limiting shafts 370 may be parallel to each other and spaced apart. Under this structure, through a plurality of spacing axle 370 that are parallel to each other, when limiting the shell fragment 360 along the direction removal of perpendicular to spacing axle 370, can also restrict the shell fragment 360 and rotate around the circumference of spacing axle 370 to still further promote damping assembly 300 overall structure's reliability.

The limiting shaft 370 may have one end fixedly connected to the supporting frame 330 and the other end not contacting the slider 400. One end of the spring piece 360 is fixedly connected with the sliding block 400, and the other end of the spring piece is not contacted with the supporting frame 330, so that the supporting frame 330 and the sliding block 400 are not blocked from sliding relatively while limiting the spring piece 360.

On this basis, referring to fig. 17, fig. 17 is a block diagram of a slider 400 according to an embodiment of the present application, a sliding groove 410 may be formed on the slider 400, and a supporting frame 330 is slidably disposed in the sliding groove 410, where a sliding direction of the supporting frame 330 with respect to the slider 400 is the same as a sliding direction of the slider 400 with respect to the door panel 210 (i.e., the second direction). The elastic pieces 360 are abutted between the supporting frame 330 and the wall of the chute 410 along the second direction.

Specifically, the support frame 330 may include a support 331 and a rolling portion 332, the support 331 is slidably disposed in the chute 410, and the rolling portion 332 is rotatably disposed on a side of the support 331 away from the elastic sheet 360 and is rotatably connected with the support 331. During the synchronous rotation of the support frame 330 (including the support 331 and the rolling portion 332) and the slider 400, the rolling portion 332 can abut against the abutment inclined surface 310 and roll along the abutment inclined surface 310, and the rotation axis of the rolling portion 332 is parallel to the rotation axis of the slider 400.

The rolling portion 332 may be a roller, and the rolling portion 332 is rotatably connected to the bracket 331, and can roll along the abutment inclined surface 310 when the rolling portion 332 abuts against the abutment inclined surface 310. Meanwhile, during the process that the rolling part 332 rolls along the abutting inclined plane 310, the rolling part 332 can push the bracket 331 to slide towards the direction close to the sliding block 400, so that the bracket 331 presses the plurality of elastic sheets 360, and a reaction force is applied to the bracket 331 and the rolling part 332 by the plurality of elastic sheets 360, so that a damping force is formed between the rolling part 332 and the abutting inclined plane 310.

In some embodiments, the support 331 may include an abutment portion 331a and a limiting portion 331b, for example, the abutment portion 331a is an abutment plate and the limiting portion 331b is a limiting plate. The elastic pieces 360 are abutted between the abutting portion 331a and the groove wall of the chute 410, and the rolling portion 332 is rotatably disposed at a side of the abutting portion 331a away from the elastic pieces 360. The abutment portions 331a are provided with limiting portions 331b at both ends in a direction parallel to the rotation axis of the slider 400, the limiting portions 331b are disposed parallel to the stacking direction (i.e., the second direction) of the plurality of elastic pieces 360, and the plurality of elastic pieces 360 are disposed between the two limiting portions 331 b. In this way, the compression direction of the plurality of elastic sheets 360 can be further limited by the two limiting portions 331b, which is more beneficial to improving the reliability of the overall structure.

The following describes in detail the rotation process of the rotation mechanism 23 provided in the present embodiment.

Referring to fig. 18, fig. 18 is a sectional view of fig. 13, and fig. 18 is a sectional view of the rotary mechanism 23 in an unfolded state. When the electronic device 01 is in the extended position, the rolling portion 332 is located on the first side of the center sill 110 in the thickness direction and abuts against the abutment slope 310. At this time, the plurality of elastic pieces 360 are not compressed, and are in a free state. When the electronic device 01 rotates from the unfolded position to the folded position, the first housing 21 and the second housing 22 respectively drive the corresponding door panels 210 to rotate along the directions a1 and a2 (the directions a1 and a2 are opposite).

In the process of rotating the electronic device 01 from the unfolded position to the folded position, referring to fig. 19, fig. 19 is a structural diagram of the rotation mechanism 23 provided in fig. 18 when starting to rotate from the unfolded position to the folded position. The rolling portions 332 on both sides of the center sill 110 respectively abut against the corresponding abutment inclined surfaces 310 and roll along the corresponding abutment inclined surfaces 310 (i.e., in the directions b1 and b2 in the drawing). Since the contact inclined surface 310 is an inclined surface, when the rolling portion 332 rolls along the contact inclined surface 310, the rolling portion 332 can push the corresponding bracket 331 to slide in the directions (the directions c1 and c2 in the drawing) approaching the slider 400, respectively, so that the bracket 331 presses the plurality of elastic pieces 360. At this time, the plurality of elastic pieces 360 are compressed, and the reaction force applied to the bracket 331 and the rolling portion 332 causes a damping force to be generated between the rolling portion 332 and the abutment inclined surface 310, so that the user can feel the damping force when turning the electronic device 01, and the situation that the user applies excessive force to cause damage to the electronic device 01 can be avoided.

Referring to fig. 20, fig. 20 is a block diagram of the rolling portion 332 of the rotating mechanism 23 according to the embodiment of the present application when it abuts against the edge of the center sill 110 (rotates from the folded position to the unfolded position). The user continues to rotate the electronic device 01, and when the rolling portion 332 is located at a position between the first side and the second side of the middle beam 110 in the thickness direction, that is, when the rolling portion 332 is located at one side of the middle beam 110 in the width direction and abuts against the middle beam 110, the pressing force applied by the elastic sheet 360 is the largest.

Referring to fig. 21, fig. 21 is a structural diagram of the rolling portion 332 of the rotating mechanism 23 according to the embodiment of the application when completely separated from the abutment inclined plane 310. The electronic device 01 continues to be turned, and the rolling portion 332 is moved beyond the center sill 110 to the second side of the center sill 110 in the thickness direction. At this time, the rolling portion 332 is completely separated from the abutment inclined surface 310, and the damping force is removed, that is, the pressing force applied to the elastic piece 360 is removed, and the energy stored in the elastic piece 360 is released, so that the elastic piece 360 rebounds and pushes the bracket 331 and the rolling portion 332 to move in a direction away from the slider 400 (directions c3 and c4 in the drawing, that is, opposite directions c1 and c2 in fig. 20). Meanwhile, an assisting force is formed for the rotation of the electronic device 01, so that the electronic device 01 rotates to a folded position rapidly, and the elastic sheets 360 rebound to a free state.

Referring to fig. 22, fig. 22 is a structural diagram illustrating a rotation mechanism 23 rotated to a folded position according to an embodiment of the present application. When the electronic device 01 rotates from the folded position to the unfolded position, the first housing 21 and the second housing 22 respectively drive the corresponding door panels 210 to rotate along the directions a3 and a4 (i.e. the opposite directions of the directions a1 and a2 in fig. 21).

In the process of rotating the electronic device 01 from the folded position to the unfolded position, referring to fig. 23, fig. 23 is a structural diagram of the rotating mechanism 23 provided in the embodiment of the application when the rotating mechanism starts to rotate from the folded position to the unfolded position. After the rolling portion 332 abuts against the edge of the middle beam 110, the electronic device 01 continues to rotate, and the rolling portion 332 is pressed by the edge of the middle beam 110, so that the rolling portion 332 moves towards the direction approaching the sliding block 400, that is, the rolling portion 332 pushes the bracket 331 to slide towards the direction approaching the sliding block 400 (the directions c1 and c2 in the figure) again, so that the bracket 331 presses the plurality of elastic sheets 360. At this time, the plurality of elastic pieces 360 are compressed, and the reaction force applied to the bracket 331 and the rolling portion 332 causes a damping force to be generated between the rolling portion 332 and the edge of the center sill 110 (i.e., the edge abutting against the inclined surface 310), so that the user can feel the damping force when turning the electronic device 01, and the situation that the user applies excessive force to cause damage to the electronic device 01 can be avoided.

Then, the user continues to rotate the electronic device 01, referring to fig. 24, fig. 24 is a diagram illustrating a structure when the rolling portion 332 of the rotating mechanism 23 provided in the embodiment of the present application abuts against the edge of the center sill 110 (rotates from the folded position to the unfolded position). The two rolling portions 332 are rotated around the center sill 110 in the directions a3 and a4, respectively, and when the rolling portions 332 are positioned between the first side and the second side of the center sill 110 in the thickness direction, that is, the rolling portions 332 are positioned at one side of the center sill 110 in the width direction and abut against the center sill 110, the pressing force applied to the elastic sheet 360 is maximized.

Referring to fig. 25, fig. 25 is a block diagram illustrating a case where the rolling portion 332 of the rotating mechanism 23 contacts the contact slope 310 according to the embodiment of the present application. The electronic device 01 continues to be turned, and the rolling portion 332 is moved beyond the center sill 110 to the first side of the center sill 110 in the thickness direction. At this time, the rolling portion 332 abuts against the edge of the abutment inclined surface 310, and the damping force disappears, that is, the pressing force applied to the elastic piece 360 disappears, and the energy stored in the elastic piece 360 is released, so that the elastic piece 360 rebounds, and the pushing bracket 331 and the rolling portion 332 move in a direction away from the slider 400 (in the directions c3 and c4 in the drawing). The rolling portion 332 rolls along the abutment inclined surface 310 (in the directions b3 and b4 in the drawing, i.e., in the directions opposite to the directions b1 and b2 in fig. 19). Meanwhile, an assisting force is formed to the rotation of the electronic device 01, so that the electronic device 01 rotates to the unfolding position shown in fig. 18 rapidly, and the plurality of elastic sheets 360 rebound to a free state. Thus, the rotation of the electronic apparatus 01 between the extended position and the folded position is completed.

The above description has been made taking the electronic device 01 as an example of a mobile phone having an external folding display screen. The electronic device 01 is described below by taking a mobile phone having an inwardly folded display as an example. Referring to fig. 26, fig. 26 is a block diagram of a rotating mechanism 23 of another electronic device 01 according to an embodiment of the present application.

When the electronic device 01 is a mobile phone with an internal folding display screen, in the rotating mechanism 23, the first component 100 is a base 120, the second component 200 is a swing arm 220, the swing arms 220 are disposed on two sides of the base 120 along the length direction, and the rotation directions of the swing arms 220 disposed on two sides of the base 120 are opposite.

The rotating mechanism 23 further includes a rotating shaft 500, the swing arm 220 is rotatably connected with the base 120 through the rotating shaft 500, the first damping portion 300a is a first cam 320, the second damping portion 300b is a second cam 340, the first cam 320 and the second cam 340 are both sleeved on the rotating shaft 500, the first cam 320 can only slide along the axial direction of the rotating shaft 500, and the second cam 340 is fixed relative to the swing arm 220, i.e. the second cam 340 rotates synchronously with the swing arm 220. The rotation shaft 500 sequentially penetrates the plurality of elastic pieces 360 along the stacking direction of the plurality of elastic pieces 360, and in the process of rotating the swing arm 220 relative to the base 120, the cam surface of the first cam 320 and the cam surface of the second cam 340 are in contact with each other and relatively rotate, so that the first cam 320 slides along the axial direction of the rotation shaft 500 and presses the plurality of elastic pieces 360.

In some embodiments, the swing arms 220 on both sides of the base 120 are respectively provided with a rotation shaft 500. Accordingly, a plurality of elastic pieces 360 may be provided on the two rotating shafts 500, respectively. Alternatively, two shafts 500 may penetrate through a plurality of elastic pieces 360 at the same time. Therefore, the present application is not particularly limited thereto.

In this way, in the process of rotating the electronic device 01 between the extended position and the folded position, the first cam 320 presses the plurality of elastic pieces 360, so that the elastic pieces 360 deform, and a reaction force is applied to the first cam 320, so that a damping force is formed between the cam surface of the first cam 320 and the cam surface of the second cam 340, and damage caused by excessive force of a user is avoided.

It will be appreciated that this embodiment provides a handset with an inner folded display that differs from the handset with an outer folded display provided in the above-described embodiments only in the construction of the damping assembly 300 and the process of generating the damping force, and the principle of rotation (i.e. rotation between the extended and folded positions) is substantially the same. Accordingly, only the damping assembly 300 of the cellular phone having the inward folding display will be described below.

Specifically, referring to fig. 27, fig. 27 is a structural diagram of the first cam 320 and the second cam 340 of the rotation mechanism 23 provided in fig. 26. The first cam 320 has a first cam surface 321, the second cam 340 has a second cam surface 341, and when the first cam surface 321 and the second cam surface 341 are engaged with each other, the protruding point on the first cam surface 321 protrudes into the recessed point on the second cam surface 341, and at the same time, the protruding point on the second cam surface 341 protrudes into the recessed point on the first cam surface 321, so as to form the engagement with each other. When the electronic device 01 is in the unfolded position, the first cam 320 and the second cam 340 are engaged with each other, no force is applied between them along the axial direction of the rotating shaft 500, and the plurality of elastic sheets 360 are in a free state.

When the electronic device 01 rotates from the unfolded position to the folded position, the swing arm 220 shown in fig. 26 drives the second cam 340 to rotate synchronously, that is, the second cam 340 rotates relative to the first cam 320, so that the first cam surface 321 rotates relative to the second cam surface 341. For example, when the second cam 340 rotates in the a direction, the first cam surface 321 and the second cam surface 341 are in contact with the inner wall of the corresponding convex point and the concave point, and the concave point and the adjacent convex point are inclined surfaces, the first cam 320 and the second cam 340 can generate a component force F along the axial direction of the rotation shaft 500 when rotating relatively; since the first cam 320 is slidable in the axial direction of the shaft 500, the component force F can slide the first cam 320 in the axial direction of the shaft 500 (the direction indicated by the component force F in the drawing) and compress the plurality of elastic pieces 360. At this time, the reaction force of the plurality of elastic pieces 360 to the first cam 320 causes the first cam 320 and the second cam 340 to abut against each other, and generates a damping force. When the electronic equipment 01 is rotated by force, the damping force can be felt, so that the damage to the electronic equipment 01 caused by overlarge force is avoided.

Then, the electronic device 01 continues to rotate, referring to fig. 28, fig. 28 is a structural diagram of the first cam 320 and the second cam 340 provided in fig. 27 when the protruding points abut against each other. When the protruding points of the first cam surface 321 and the second cam surface 341 abut against each other, the plurality of elastic pieces 360 receive the largest pressing force, and the elastic pieces apply the reaction force F1 to the first cam 320.

Referring to fig. 29, fig. 29 is a diagram illustrating a structure of the first cam 320 and the second cam 340 provided in fig. 28 when the protruding points are offset from each other. The second cam 340 continues to rotate along the direction a, and the first cam surface 321 and the second cam surface 341 are at positions where the protruding points are offset from each other, that is, the protruding points are all rotated to positions corresponding to the adjacent other recessed points.

At this time, the extrusion force applied by the first cam 320 to the elastic sheet 360 disappears, the energy stored by the elastic sheet 360 is released, and under the elastic force of the elastic sheet 360, that is, under the action of the reaction force F1 applied by the elastic sheet 360 to the first cam 320, the first cam 320 slides in the direction close to the second cam 340 (the direction indicated by the reaction force F1 in the figure), and the convex point rapidly stretches into another adjacent concave point, so that the electronic device 01 rapidly rotates to the folded position, that is, the rotation of the electronic device 01 forms an assistance, the user does not need to continuously apply external force, the rotation of the electronic device 01 can be completed, the hand feeling of the user in use is promoted, and the user is reminded that the electronic device 01 has rotated to the folded position, thereby being favorable for protecting the electronic device 01.

The process of rotating the electronic device 01 from the folded position to the unfolded position is the same as the process of rotating the electronic device from the unfolded position to the folded position, and thus, a description thereof will not be repeated.
