Description

Technical Field

[0001] This application belongs to the field of electronic equipment technology, specifically relating to a folding mechanism and an electronic device. Background Technology

[0002] Currently, folding phones are favored by consumers for their portability and large screen. Folding phones achieve folding and unfolding through folding mechanisms (such as hinges). The hinges of most folding products consist of four modules: synchronization mechanism, damping mechanism, virtual mechanism, and door panel mechanism.

[0003] In related technologies, the damping mechanism and synchronization mechanism of the hinge are designed together, which is relatively complex. This makes the hinge difficult to process, increases the cost of the hinge, increases the number of parts, and makes the overall weight of the hinge heavier. Summary of the Invention

[0004] This application aims to provide a folding mechanism and an electronic device that at least solves the problem of the large number of parts in folding mechanisms in related technologies.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application propose a folding mechanism, comprising: a support; a first hinge module and at least one second hinge module, each of the first and second hinge modules including a swing arm assembly and a damping assembly; the swing arm assembly including a first swing arm and a second swing arm, the first and second swing arms being disposed opposite to each other and rotatably connected to the support to enable the folding mechanism to unfold or fold, the first and second swing arms being provided with a first cam portion; the damping assembly being disposed on the support, the damping assembly being provided with a second cam portion and an elastic portion, the first cam portion and the second cam portion cooperating to move, and when the first and second swing arms rotate relative to the support, the first cam portion and the second cam portion drive the elastic portion to deform, wherein the first hinge module further includes a synchronization assembly, the first and second swing arms in the first hinge module rotating synchronously through the synchronization assembly, and the first hinge module and at least one second hinge module rotating synchronously through the synchronization assembly.

[0007] Secondly, embodiments of this application provide an electronic device including a folding mechanism as described in any of the first aspects.

[0008] In embodiments of this application, the folding mechanism includes a support, a first hinge module, and at least one second hinge module. Both the first and second hinge modules include a swing arm assembly and a damping assembly. The first hinge module also includes a synchronization assembly. The swing arm assembly includes a first swing arm and a second swing arm rotatably connected to the support. The first and second swing arms rotate relative to the support to unfold or fold the folding mechanism. A first cam portion is provided on the first and second swing arms, and a second cam portion and an elastic portion are provided on the damping assembly. During the rotation of the first and second swing arms, the first cam portion drives the elastic portion to deform through the second cam portion, thereby achieving suspension of the folding mechanism through the damping force of the damping assembly. The first and second swing arms in the first hinge module rotate synchronously through the synchronization assembly. The first hinge module and at least one second hinge module can also rotate synchronously through the synchronization assembly. That is, synchronous rotation of the first hinge module and at least one second hinge module is achieved through the same synchronization assembly, reducing the number of synchronization assemblies, thereby reducing the number of parts in the folding mechanism and lowering its weight, space occupation, and manufacturing cost.

[0022] The following is combined Figures 1-5 This application describes a folding mechanism and an electronic device according to embodiments thereof.

[0023] like Figure 1 and Figure 2As shown, the folding mechanism includes: a support 1; a first hinge module 10 and at least one second hinge module 11, both the first hinge module 10 and the second hinge module 11 including a swing arm assembly 102 and a damping assembly 12; the swing arm assembly 102 includes a first swing arm 104 and a second swing arm 106, the first swing arm 104 and the second swing arm 106 are arranged opposite to each other and rotatably connected to the support 1 to allow the folding mechanism to unfold or fold, and the first swing arm 104 and the second swing arm 106 are provided with a first cam portion 108; the damping assembly 12 is disposed on the support 1, and the damping assembly 1... The first hinge module 10 is provided with a second cam portion and an elastic portion 124. The first cam portion 108 and the second cam portion move in coordination. When the first swing arm 104 and the second swing arm 106 rotate relative to the bracket 1, the first cam portion 108 and the second cam portion drive the elastic portion 124 to deform. The first hinge module 10 also includes a synchronization component 2. The first swing arm 104 and the second swing arm 106 in the first hinge module 10 rotate synchronously through the synchronization component 2. The first hinge module 10 and at least one second hinge module 11 rotate synchronously through the synchronization component 2.

[0024] In embodiments of this application, the folding mechanism includes a support 1, a first hinge module 10, and at least one second hinge module 11. Both the first hinge module 10 and the second hinge module 11 include a swing arm assembly 102 and a damping assembly 12. The first hinge module 10 further includes a synchronization assembly 2. The swing arm assembly 102 includes a first swing arm 104 and a second swing arm 106 rotatably connected to the support 1. The first swing arm 104 and the second swing arm 106 rotate relative to the support 1 to unfold or fold the folding mechanism. A first cam portion 108 is provided on the first swing arm 104 and the second swing arm 106. The damping assembly 12 is provided with a second cam portion and an elastic portion 124. During the rotation of the first swing arm 104 and the second swing arm 106, the first cam portion 108 drives the elastic portion 124 to deform through the second cam portion, thereby achieving suspension of the folding mechanism through the damping force of the damping assembly 12. In this design, the first hinge arm 104 and the second hinge arm 106 in the first hinge module 10 rotate synchronously via the synchronization component 2. The first hinge module 10 and at least one second hinge module 11 can also rotate synchronously via the synchronization component 2, ensuring the reliability of the folding mechanism's folding or unfolding. In other words, the synchronous rotation of the first hinge module 10 and at least one second hinge module 11 is achieved through the same synchronization component 2, reducing the number of synchronization components 2, thereby reducing the number of parts in the folding mechanism and lowering its weight, space occupation, and manufacturing cost.

[0025] It is understood that in the folding mechanism proposed in this application, the synchronization component 2 is separately set in the first hinge module 10, and is set separately from the damping component 12, so that the damping component 12 is integrated with the swing arm component 102, thereby reducing the number of synchronization components 2, so as to reduce the weight and cost of the folding mechanism.

[0026] In specific applications, such as Figure 2 , Figure 3 and Figure 4 As shown, the number of first hinge modules 10 is one set, and the number of second hinge modules 11 is one set. The second hinge module 11 includes a swing arm assembly 102 and a damping assembly 12, and the first hinge module 10 includes a swing arm assembly 102, a damping assembly 12 and a synchronization assembly 2.

[0027] Furthermore, under the action of the first cam portion 108 and the second cam portion (not shown in the figure), the damping component 12 moves along the rotation axis of the first swing arm 104 and the second swing arm 106, thereby deforming and providing damping force for the folding mechanism, thus enabling the folding mechanism to hover.

[0028] like Figure 5 As shown, in some embodiments of the folding mechanism of this application, the first hinge module 10 further includes a mounting part 14, which is connected to the bracket 1, and the synchronization component 2 is disposed on the mounting part 14.

[0029] In this embodiment, a mounting part 14 is provided on the first hinge module 10 with the synchronization component 2 for mounting the synchronization component 2. The mounting part 14 is located at the end of the damping component 12 away from the swing arm component 102, which facilitates the fixing of the synchronization component 2 and thus ensures the reliability of the synchronous rotation of the first swing arm 104 and the second swing arm 106.

[0030] According to some embodiments of this application, the folding mechanism further includes: a first connecting frame 3, wherein the first swing arm 104 of the first hinge module 10 and the first swing arm 104 of the second hinge module 11 are both connected to the first connecting frame 3, and the first connecting frame 3 is connected to the synchronization component 2; and a second connecting frame 4, which is correspondingly arranged to the first connecting frame 3, wherein the second swing arm 106 of the first hinge module 10 and the second swing arm 106 of the second hinge module 11 are both connected to the second connecting frame 4, and the second connecting frame 4 is connected to the synchronization component 2.

[0031] In this embodiment, the folding mechanism further includes a first connecting frame 3 and a second connecting frame 4. The first connecting frame 3 and the second connecting frame 4 are connected to the synchronization component 2. The first swing arm 104 of the first hinge module 10 and the first swing arm 104 of the second hinge module 11 are connected through the first connecting frame 3, thereby enabling the first swing arm 104 of the first hinge module 10 and the first swing arm 104 of the second hinge module 11 to rotate synchronously around the support 1. The second swing arm 106 of the first hinge module 10 and the second swing arm 106 of the second hinge module 11 are both connected to the second connecting frame 4, enabling the second swing arm 106 of the first hinge module 10 and the second swing arm 106 of the second hinge module 11 to rotate synchronously around the support 1, thereby enabling the first hinge module 10 and the second hinge module 11 to achieve synchronous rotation through the same synchronization component 2.

[0032] like Figure 5 As shown, according to some embodiments of this application, the synchronization component 2 includes: a first rotating shaft 20, disposed on the mounting portion 14, with a first connecting frame 3 connected to the first rotating shaft 20; a second rotating shaft 22, disposed on the mounting portion 14, corresponding to the first rotating shaft 20, with a second connecting frame 4 connected to the second rotating shaft 22; and a synchronization element 24, disposed between the first rotating shaft 20 and the second rotating shaft 22, with the first rotating shaft 20 and the second rotating shaft 22 rotating synchronously via the synchronization element 24.

[0033] In this embodiment, the synchronization component 2 includes a first rotating shaft 20, a second rotating shaft 22, and a synchronization element 24. The first rotating shaft 20 and the second rotating shaft 22 are disposed in the mounting part 14 and are correspondingly disposed. The synchronization element 24 is disposed between the first rotating shaft 20 and the second rotating shaft 22 and is connected to the first rotating shaft 20 and the second rotating shaft 22, so that the first rotating shaft 20 and the second rotating shaft 22 can rotate synchronously, thereby causing the first connecting frame 3 connected to the first rotating shaft 20 and the second connecting frame 4 connected to the second rotating shaft 22 to rotate synchronously, thereby causing the first swing arm 104 and the second swing arm 106 of the first hinge module 10 to rotate synchronously, thereby realizing the synchronous rotation of the first hinge module 10 and the second hinge module 11.

[0034] It is understandable that the first rotating shaft 20 is movably connected to the mounting part 14, so that the first rotating shaft 20 can rotate relative to the mounting part 14, and the second rotating shaft 22 is movably connected to the mounting part 14, so that the second rotating shaft 22 can rotate relative to the mounting part 14.

[0035] In practical applications, the first connecting frame 3 and the first rotating shaft 20 are relatively fixed in the rotation direction of the first connecting frame 3, and the second connecting frame 4 and the second rotating shaft 22 are relatively fixed in the rotation direction of the first connecting frame 3, so as to ensure that the first connecting frame 3 can rotate with the rotation of the first rotating shaft 20, and the second connecting frame 4 can rotate with the rotation of the second rotating shaft 22.

[0036] like Figure 5 As shown, according to some embodiments of this application, the synchronization component 2 further includes a first synchronization swing arm 26 and a second synchronization swing arm 28; the first synchronization swing arm 26 is connected to the first rotating shaft 20, the first connecting frame 3 is movably connected to the first synchronization swing arm 26, the second synchronization swing arm 28 is connected to the second rotating shaft 22 and is correspondingly arranged with the first synchronization swing arm 26, and the second connecting frame 4 is movably connected to the second synchronization swing arm 28.

[0037] In this embodiment, the synchronization component 2 further includes a first synchronization swing arm 26 and a second synchronization swing arm 28. The first synchronization swing arm 26 connects the first rotating shaft 20 and the first connecting frame 3, and the second synchronization swing arm 28 connects the second rotating shaft 22 and the second connecting frame 4. The first synchronization swing arm 26 is movably connected to the first connecting frame 3, allowing the first connecting frame 3 to slide relative to the first synchronization swing arm 26. The second synchronization swing arm 28 is movably connected to the second connecting frame 4, allowing the second connecting frame 4 to slide relative to the second synchronization swing arm 28. Thus, when the folding mechanism is folded or unfolded, the first connecting frame 3 and the second connecting frame 4 can rise away from the synchronization component 2 while rotating, ensuring the reliability of the unfolding and folding of the folding mechanism.

[0038] Understandably, the first connecting frame 3 and the first synchronous swing arm 26 cannot rotate relative to each other, allowing the first connecting frame 3 to rotate with the first synchronous swing arm 26. Correspondingly, the second connecting frame 4 and the second synchronous swing arm 28 cannot rotate relative to each other, allowing the second connecting frame 4 to rotate with the first synchronous swing arm 26, thereby achieving synchronous rotation of the first swing arm 104 and the second swing arm 106. Furthermore, the first connecting frame 3 and the first synchronous swing arm 26 can slide vertically, and the second connecting frame 4 and the second synchronous swing arm 28 can slide vertically, allowing the first connecting frame 3 and the second connecting frame 4 to rise relative to the synchronous assembly 2, ensuring the reliability of folding or unfolding.

[0039] In practical applications, the first connecting frame 3 and the second connecting frame 4 are fixed supports for the middle frame.

[0040] Furthermore, such as Figure 5 As shown, the folding mechanism also includes door panels, which include a first door panel 5 and a second door panel 6 arranged opposite to each other. The first door panel 5 is connected to the first connecting frame 3, and the second door panel 6 is connected to the second connecting frame 4.

[0041] like Figure 5 As shown, according to some embodiments of this application, the synchronizing element 24 includes a first gear 240 and a second gear 242 that mesh with each other. A first tooth is provided on a first rotating shaft 20 and a second tooth is provided on a second rotating shaft 22. The first gear 240 meshes with the first tooth and the second gear 242 meshes with the second tooth.

[0042] In this embodiment, the synchronizing element 24 includes a first gear 240 and a second gear 242 that mesh with each other. The first rotating shaft 20 is provided with a first tooth for meshing with the first gear 240, and the second rotating shaft 22 is provided with a second tooth for meshing with the second gear 242. Through the cooperation of the first gear 240 and the second gear 242, the first rotating shaft 20 and the second rotating shaft 22 are rotated synchronously. The synchronous rotation achieved by gear meshing ensures the smoothness of the movement of the first rotating shaft 20 and the second rotating shaft 22.

[0043] According to some embodiments of the present application, the folding mechanism of the damping assembly 12 further includes: a seat 122, which is movably connected to the bracket 1 along the rotation axis of the first swing arm 104; a second cam portion is disposed on the seat 122; and the end of the seat 122 is correspondingly disposed with the end of the elastic portion 124 for driving the elastic portion 124 to deform.

[0044] In this embodiment, the damping assembly 12 further includes a seat 122. Along the rotation axis of the first swing arm 104, the seat 122 is movably connected to the bracket 1. A second cam portion is disposed on the seat 122, and an elastic portion 124 is disposed on the bracket 1. When the first swing arm 104 and the second swing arm 106 rotate, under the action of the second cam portion and the first cam portion 108, the seat 122 compresses the elastic portion 124, causing the elastic portion 124 to deform along the rotation axis, so that the damping assembly 12 has a damping force, thereby achieving the suspension of the folding mechanism.

[0045] In specific applications, the elastic part 124 includes a spring.

[0046] It is understood that the first cam 1080 and the second cam are respectively arranged along the rotation axis of the first rocker arm 104. When the first rocker arm 104 and the second rocker arm 106 rotate, the first cam 1080 is driven to rotate, which causes the engagement position of the first cam 1080 and the second cam to change, thereby causing the second cam to be displaced in the direction of the rotation axis, so as to drive the base to move, thereby causing the elastic part 124 to deform.

[0047] According to some embodiments of the folding mechanism of this application, in any damping component 12, there are multiple elastic parts 124, and the multiple elastic parts 124 are arranged side by side.

[0048] In this embodiment, the first hinge module 10 includes a damping component 12, and the second hinge module 11 includes a damping component 12. Therefore, the number of damping components 12 is at least two. In any damping component 12, the number of elastic parts 124 is multiple. The arrangement of multiple elastic parts 124 can increase the damping force of the damping component 12 and improve the opening and closing feel of the folding mechanism. The parallel arrangement of multiple elastic parts 124 can reduce the space occupied by the elastic parts 124 in the rotation axis of the first swing arm 104 and the second swing arm 106, thereby facilitating the miniaturization of the folding mechanism. At the same time, since the parallel arrangement of multiple elastic parts 124 reduces the axial length, multiple second hinge modules 11 can be provided, thereby increasing the number of damping mechanisms and thus increasing the damping force.

[0049] Furthermore, such as Figure 2 and Figure 5 As shown, the first hinge module 10 and the second hinge module 11 each include two elastic parts 124, and the two elastic parts 124 are movably connected to the bracket 1.

[0050] According to some embodiments of the present application, the folding mechanism further includes: a hinge cover, a first hinge module 10 and at least one second hinge module 11 disposed on the hinge cover, the first hinge module 10 and at least one second hinge module 11 being distributed along the rotation axis of the first swing arm 104.

[0051] In this embodiment, the folding mechanism further includes a hinge cover, on which a first hinge module 10 and at least one second hinge module 11 are disposed to enable the installation of the first hinge module 10 and at least one second hinge module 11.

[0052] In a specific application, the folding mechanism includes two sets of hinge modules. The first hinge module 10 includes a swing arm assembly 102, a damping assembly 12, and a synchronization assembly 2. The synchronization assembly 2 is located on the side of the damping assembly 12 close to the second hinge module 11. The second hinge module 11 includes the swing arm assembly 102 and the damping assembly 12. The damping assembly 12 of the second hinge module 11 is located on the side of the swing arm assembly 102 close to the first hinge module 10.

[0053] According to one embodiment of this application, an electronic device is proposed, including a folding mechanism as described in any of the above embodiments, thus having all the beneficial effects of a folding mechanism, which will not be repeated here.

[0054] It should be noted that electronic devices include mobile phones, tablets, computers, wearable devices, etc.

[0055] In practical applications, the folding mechanism proposed in this application is based on the functions of the hinge of the folding machine: folding and hovering. The hinge layout and scheme have been completely modified to achieve the effect of reducing the weight and cost of the hinge, thereby making the folding machine more efficient.

[0056] Based on the current basic principle of hinges: crank-slider mechanism, the design space of hinges is improved, the number of parts is reduced, and the weight and cost of hinges are reduced.

[0057] In related technologies, the damping mechanism (e.g., damping component 12) and the synchronization mechanism (e.g., synchronization component 2) are integrated. Due to the damping requirements of the entire machine, two sets of synchronization mechanisms are needed, resulting in a large number of parts.

[0058] This application replaces the damping mechanism (e.g., damping component 12) with a swing arm assembly 102 (e.g., virtual swing arm), reducing one set of synchronization mechanisms and reducing the number of parts by approximately 10.

[0059] The main approach is as follows: the top and bottom hinges consist of two sets of hinge modules. One set combines the virtual swing arm with the damping mechanism, while the synchronization mechanism is made as a separate part. The other set only contains the virtual swing arm and the damping mechanism. Based on this solution, one set of synchronization mechanism can be reduced, and the number of parts can be reduced by about 10.

[0060] Its main components are:

[0061] ①For example Figure 3 As shown, the first hinge module 10 includes: a virtual mechanism (e.g., a virtual swing arm), a synchronization mechanism, and a damping mechanism.

[0062] ②For example Figure 4 As shown, the second hinge module 11 includes: a virtual mechanism (e.g., a virtual swing arm) and a damping mechanism.

[0063] Compared to the current mainstream top and bottom hinges, its main components are reduced by more than ten parts. The main reduction is in the synchronization mechanism, which is reduced by one set. Furthermore, the virtual swing arm is combined with the damping mechanism, making the structure simpler and clearer.

[0064] This invention addresses the pain points of current folding phone designs by researching hinge reduction and cost-saving solutions. It reduces the number of hinge parts, thereby achieving cost and weight reduction, and enhancing the overall user experience and competitiveness of the device. This application applies to all folding phone hinges (including left-right and up-down folding hinges).
