Description

Technical Field

[0001] This application belongs to the field of folding structure technology, specifically relating to folding devices, housing assemblies, electronic devices, and foldable electronic devices. Background Technology

[0002] With the continuous development of display technology, various types of electronic devices have been launched. Foldable electronic devices, which can achieve a small overall size and a large display area, are increasingly favored by users. Currently, most foldable electronic devices use folding mechanisms for folding, but the overall size of these mechanisms is currently quite large. Summary of the Invention

[0003] In view of this, the first aspect of this application provides a folding device, comprising: support; A first rotating mechanism and a second rotating mechanism are arranged side by side. Each of the first rotating mechanism and the second rotating mechanism includes a first rotating component, a second rotating component, and a connecting component. One end of the first rotating component and the second rotating component are rotatably connected to the bracket, and the other end of the first rotating component and the second rotating component are rotatably connected to the connecting component. The first rotation axis between the first rotating component and the connecting component is parallel and does not coincide with the second rotation axis between the second rotating component and the connecting component. The support mechanism includes a first support member and a second support member disposed on opposite sides of the bracket, wherein the first support member is rotatably connected to a connecting member of the first rotating mechanism, and the second support member is rotatably connected to a connecting member of the second rotating mechanism; and The driven mechanism includes a first driven member and a second driven member disposed on opposite sides of the bracket. One end of the first driven member is slidably and rotatably connected to the bracket, and the other end is rotatably connected to the connecting member of the first rotating mechanism, and the other end is also slidably and rotatably connected to the first support member. One end of the second driven member is slidably and rotatably connected to the bracket, and the other end is rotatably connected to the connecting member of the second rotating mechanism, and the other end is also slidably and rotatably connected to the second support member. When the folding device is folded, the first driven member, the second driven member, and the first rotating member and the second rotating member of the first rotating mechanism and the second rotating mechanism rotate, while the first driven member and the second driven member also slide, and the first support member and the second support member fold together; when the folding device is unfolded, the first driven member, the second driven member, and the first rotating member and the second rotating member of the first rotating mechanism and the second rotating mechanism rotate, while the first driven member and the second driven member also slide, and the first support member and the second support member unfold together.

[0004] The folding device provided in the first aspect of this application achieves the mutual folding and unfolding of two supporting members through the cooperation of a bracket, a rotating mechanism, a supporting mechanism, and a driven mechanism, thus realizing the folding and unfolding functions of the folding device. Furthermore, the first and second rotating members are parallel to, and do not coincide with, the first and second rotation axes between them and the connecting member. This allows for normal movement of the supporting members while maintaining a small length of the folding device with no change in its length direction, resulting in a compact structure. This reduces the size of the folding device and the internal space occupied by the housing assembly and electronic device, which is beneficial for the layout of other structural components such as the motherboard or battery. Compared to related technologies where the connecting member can slide relative to the rotating member, this also facilitates the miniaturization of the folding device.

[0005] In addition, the fact that the first rotation axis is parallel to and does not coincide with the second rotation axis ensures that the connecting member will not rotate relative to the first and second rotating members, thus improving the stability of the folding device.

[0006] A second aspect of this application provides a housing assembly including a first housing, a second housing, and a folding device as provided in the first aspect of this application. At least portions of the first housing and the second housing are disposed on opposite sides of the folding device. The first housing is connected to a connector of a first rotating mechanism of the folding device, and the second housing is connected to a connector of a second rotating mechanism of the folding device. When the connecting parts of the first rotating mechanism and the second rotating mechanism rotate, the first housing and the second housing switch between an unfolded state and a folded state.

[0007] A third aspect of this application provides an electronic device comprising a flexible element and a housing assembly as provided in the second aspect of this application. The flexible element is supported by a first support and a second support of the folding device. When the electronic device is folded, the first housing and the second housing fold together, the first support and the second support fold together, and the two ends of the flexible element fold together. When the electronic device is unfolded, the first housing and the second housing unfold together, the first support and the second support unfold together, and the two ends of the flexible element unfold together.

Each of the first rotating mechanism and the second rotating mechanism includes a first rotating component, a second rotating component, and a connecting component. One end of the first rotating component and the second rotating component are rotatably connected to the bracket, and the other end of the first rotating component and the second rotating component are rotatably connected to the connecting component. The first rotation axis between the first rotating component and the connecting component is parallel and does not coincide with the second rotation axis between the second rotating component and the connecting component. A support mechanism for supporting a flexible component includes a first support member and a second support member disposed on opposite sides of the bracket. The first support member is rotatably connected to a connecting member of a first rotating mechanism, and the second support member is rotatably connected to a connecting member of a second rotating mechanism. The driven mechanism includes a first driven member and a second driven member disposed on opposite sides of the bracket. One end of the first driven member is slidably and rotatably connected to the bracket, and the other end is rotatably connected to the connecting member of the first rotating mechanism, and the other end is also slidably and rotatably connected to the first support member. One end of the second driven member is slidably and rotatably connected to the bracket, and the other end is rotatably connected to the connecting member of the second rotating mechanism, and the other end is also slidably and rotatably connected to the second support member. When the folding device is folded, the first driven member, the second driven member, and the first rotating member and the second rotating member of the first rotating mechanism and the second rotating mechanism rotate, while the first driven member and the second driven member also slide. The first support member and the second support member fold each other, and the two ends of the flexible member fold each other. When the folding device is unfolded, the first driven member, the second driven member, and the first rotating member and the second rotating member of the first rotating mechanism and the second rotating mechanism rotate, while the first driven member and the second driven member also slide. The first support member and the second support member unfold each other, and the two ends of the flexible member unfold each other. Attached Figure Description

Detailed Implementation

[0058] The following are preferred embodiments of this application. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of this application, and these improvements and modifications are also considered to be within the scope of protection of this application.

[0059] Before introducing the technical solution of this application, let's go over the technical issues in related technologies in detail.

[0060] With the continuous development of display technology, users have increasingly higher requirements for electronic devices, leading to the development and launch of various electronic devices, such as foldable electronic devices, rollable electronic devices, and scrollable electronic devices. Among them, foldable electronic devices, due to their unique folding performance, offer a large display area when unfolded and a small overall size when folded, and are now increasingly popular among users. Foldable electronic devices can be divided into inward folding and outward folding based on the bending direction. Inward folding means that the two halves of the flexible screen are close to each other and protected by the shell, so that the flexible screen is not visible to the user when folded. Outward folding means that the two halves of the flexible screen are far apart from the shell. Although the flexible screen is not protected by the shell, the user can still view its display when folded. Furthermore, for inward folding, based on the cross-sectional shape of the folded flexible screen, it can be divided into U-shaped and teardrop-shaped. The U-shaped shape is named because the cross-sectional shape of the flexible screen after bending resembles the letter U. The teardrop-shaped shape is named because the cross-sectional shape of the flexible screen after bending resembles the shape of a teardrop. In other words, the teardrop-shaped flexible screen has a smaller gap between the two halves of the screen at the top and a larger gap at the bottom.

[0061] Whether folding inwards or outwards, forming a U-shape or a teardrop shape, current methods for achieving the folding function of foldable electronic devices typically employ a folding mechanism installed within the device. This folding mechanism relies on its supporting component moving relative to a bracket, and through the cooperation of other structural components, moves along a pre-set trajectory, thus constraining the flexible component into a U-shape or teardrop shape when folded. However, current folding mechanisms are complex in structure, have a large overall width, and occupy considerable space, hindering miniaturization. For example, some folding mechanisms have connectors that can slide relative to rotating components. This causes changes in the dimensions of the folding mechanism, the housing assembly using the folding mechanism, and the electronic device along their length, resulting in a more complex structure, increased overall length, and greater space occupation, thereby reducing the space available for other structural components such as the motherboard or battery. Furthermore, the sliding structure cannot support the connectors in the event of an emergency (such as a drop), affecting the reliability of the folding mechanism.

[0062] Therefore, in order to solve the above problems, this application provides a folding device. Please refer to the following: Figures 1-8 , Figure 1 This is a three-dimensional structural diagram of the folding device in the unfolded state according to one embodiment of this application. Figure 2 for Figure 1 The folding device shown is a three-dimensional structural diagram from another perspective. Figure 3 for Figure 1 Exploded view of the folding device.

[0063] This embodiment provides a folding device 1, including a support 10, and a first rotating mechanism 20 and a second rotating mechanism 20' arranged side by side on opposite sides of the support 10. Each of the first rotating mechanism 20 and the second rotating mechanism 20' includes a first rotating member 21, a second rotating member 22, and a connecting member 23. One end of each of the first rotating member 21 and the second rotating member 22 is rotatably connected to the support 10, and the other end of each is rotatably connected to the connecting member 23. The first rotation axis C1 between the first rotating member 21 and the connecting member 23 is parallel to and does not coincide with the second rotation axis C2 between the second rotating member 22 and the connecting member 23. A support mechanism 30 includes a first support member 31 and a second support member 31' located on opposite sides of the support 10. The first support member 31 is rotatably connected to the connecting member 23 of the first rotating mechanism 20, and the second support member 31' is rotatably connected to the connecting member 23 of the second rotating mechanism 20'. The driven mechanism 70 includes a first driven member 71 and a second driven member 71' disposed on opposite sides of the bracket 10. One end of the first driven member 71 is slidably and rotatably connected to the bracket 10, and the other end is rotatably connected to the connector 23 of the first rotating mechanism 20, and the other end is also slidably and rotatably connected to the first support member 31. One end of the second driven member 71' is slidably and rotatably connected to the bracket 10, and the other end is rotatably connected to the connector 23 of the second rotating mechanism 20', and the other end is also slidably and rotatably connected to the second support member 31'. When the folding device 1 is folded, the first driven member 71, the second driven member 71', and the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 and the second rotating mechanism 20' rotate, while the first driven member 71 and the second driven member 71' also slide, and the first support member 31 and the second support member 31' fold together; when the folding device 1 is unfolded, the first driven member 71, the second driven member 71', and the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 and the second rotating mechanism 20' rotate, while the first driven member 71 and the second driven member 71' also slide, and the first support member 31 and the second support member 31' unfold together.

[0064] The folding device 1 is a device capable of relative rotation to achieve folding and unfolding, possessing a folding function. The folding device 1 provided in this embodiment can be applied to various fields, such as door locks, vehicles, machinery, and electronic products. This embodiment only illustrates the application of the folding device 1 to a foldable electronic device in the field of electronic products. Of course, applications of the folding device 1 to other fields should also fall within the scope of protection of this application.

[0065] Furthermore, the aforementioned electronic devices include, but are not limited to, mobile terminals such as mobile phones, tablets, laptops, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, and pedometers, as well as fixed terminals such as digital TVs and desktop computers. This embodiment is only illustrative when the electronic device is a mobile phone. Of course, in other embodiments, the electronic device can be of other types, and should also fall within the protection scope of this application.

[0066] The folding device 1 mainly includes a bracket 10, two rotating mechanisms, a support mechanism 30, and a driven mechanism 70. This embodiment solves the aforementioned technical problems using only the bracket 10, two rotating mechanisms, support mechanism 30, and driven mechanism 70. However, this does not mean that the folding device 1 can only have these mechanisms; the folding device 1 can also have other mechanisms such as a synchronization mechanism, a hovering mechanism, etc. Next, this embodiment will describe the bracket 10, two rotating mechanisms, support mechanism 30, and driven mechanism 70 in detail.

[0067] The bracket 10 is a basic structural component in the folding device 1, mainly serving a supporting and mounting function. It allows other structural components in the folding device 1, such as rotating components and driven components 71, to be mounted on the bracket 10. In some embodiments, the bracket 10 can also support components to be supported. These components include, but are not limited to, various flexible components, various rigid components, or other parts. This embodiment does not limit the shape, structure, material, or other parameters of the bracket 10, as long as it provides an assembly base for other structural components.

[0068] Optionally, the bracket 10 has a top surface 101 and a bottom surface 102 arranged opposite to each other, two first side surfaces 103 bent and connected between the top surface 101 and the bottom surface 102, and two second side surfaces 104. The two first side surfaces 103 are spaced apart, and the two second side surfaces 104 are spaced apart, with the two second side surfaces 104 bent and connected to opposite sides of the two first side surfaces 103. The first side surfaces 103 are close to the subsequent rotating mechanism 20, and the shape of the first side surfaces 103 is arc-shaped so that the width of the top surface 101 is greater than the width of the bottom surface 102. Since the top surface 101 needs to be equipped with various structural components, while the bottom surface 102 usually does not need to assemble components or has fewer components, making the top surface 101 larger and the bottom surface 102 smaller can reduce the size of the bracket 10 and accommodate more structural components. In addition, the arc-shaped design of the first side surfaces 103 can avoid the rotating mechanism 20 or other structural components such as the housing during movement, preventing interference problems during movement. The second side 104 can be designed as a plane so that other structural components can be installed on the second side 104, such as the driven mechanism 70, the synchronization mechanism, the hovering mechanism, etc.

[0069] The rotating mechanism is one of the core mechanisms in the folding device 1. It primarily enables the folding device 1 to rotate, driving and limiting the components connected to it, causing these components to move along a preset trajectory. The first rotating mechanism 20 mainly includes a first rotating member 21, a second rotating member 22, and a connecting member 23. The first rotating member 21 and the second rotating member 22 primarily function as rotational components, while the connecting member 23 primarily serves as an intermediate connection and is subsequently fixed to the housing. One end of the first rotating member 21 is rotatably connected to the support 10, meaning the end of the first rotating member 21 closest to the support 10 is rotatably connected to the support 10. In other words, the support 10 is usually fixed, so the first rotating member 21 can rotate relative to the support 10. Similarly, one end of the second rotating member 22 is also rotatably connected to the support 10, meaning the end of the second rotating member 22 closest to the support 10 is rotatably connected to the support 10. In other words, the support 10 is usually fixed, so the second rotating member 22 can rotate relative to the support 10. The specific cooperation structure between the first rotating member 21, the second rotating member 22, and the bracket 10 will be described in detail later in this application.

[0070] The other end of the first rotating member 21 is rotatably connected to the connecting member 23, that is, the end of the first rotating member 21 away from the support 10 is rotatably connected to the connecting member 23. In other words, the first rotating member 21 can rotate relative to the connecting member 23. Similarly, the other end of the second rotating member 22 is also rotatably connected to the connecting member 23, that is, the end of the second rotating member 22 away from the support 10 is rotatably connected to the connecting member 23. In other words, the second rotating member 22 can rotate relative to the connecting member 23. The specific cooperation structure between the first rotating member 21, the second rotating member 22, and the support 10 will be described in detail later in this application. The rotatable connection between the two rotating members and the connecting member 23 ensures that the connecting member 23 will only rotate relative to the two rotating members and will not slide, thus preventing the connecting member 23 from sliding relative to the two rotating members and increasing the size of the folding device 1, achieving the goal of miniaturization of the folding device 1. Furthermore, the rotatable connection between the two rotating members and the connecting member 23 allows the rotating structure to effectively support the connecting member 23 in the event of an emergency (such as a fall), improving the reliability of the folding device 1.

[0071] The connector 23 can be fixed to the housing, thereby enabling the connector 23 to rotate when the housing rotates. In some embodiments, the connector 23 and the housing can be an integral or separate structure. When the connector 23 and the housing are an integral structure, they are manufactured in one process; however, for ease of understanding, the connector 23 and the housing are given different names. When the connector 23 and the housing are separate structures, they are manufactured separately and then fixed to the housing by various methods such as bonding, screw connection, and snap-fit ​​connection. This embodiment is only illustrated with the example of a separate structure for the connector 23 and the housing.

[0072] This embodiment does not limit the shape, structure, material, or other parameters of the first rotating member 21, the second rotating member 22, and the connecting member 23. As long as one end of the first rotating member 21 and the second rotating member 22 can be rotatably connected to the bracket 10, and the other end of the first rotating member 21 and the second rotating member 22 can be rotatably connected to the connecting member 23, it is acceptable.

[0073] Furthermore, when the first rotating member 21 is rotatably connected to the connecting member 23, the first rotating member 21 and the connecting member 23 have a first rotation axis C1 (e.g., Figure 4 (As shown in C1). When the second rotating member 22 is rotatably connected to the connecting member 23, the second rotating member 22 and the connecting member 23 have a second rotation axis C2 (as shown in C1). Figure 4 (As shown in the C2 direction). This embodiment allows the first rotation axis C1 and the second rotation axis C22 to be parallel to each other. "Parallel to each other" means that the extension direction of the first rotation axis C1 is the same as the extension direction of the second rotation axis C2, and there is a certain distance between the first rotation axis C1 and the second rotation axis C2; that is, the first rotation axis C1 and the second rotation axis C2 are parallel to each other and do not coincide. This design ensures that when the folding device 1 is stationary (i.e., when the folding device 1 is not rotating), the connecting member 23 is restricted from rotating relative to the first rotating member 21 and the second rotating member 22, maintaining relative stillness with respect to the first rotating member 21 and the second rotating member 22, thus improving the structural stability of the folding device 1. However, when the folding device 1 is in motion, the rotation of the connecting member 23 can still drive the first rotating member 21 and the second rotating member 22 to rotate, and the first rotating member 21 and / or the second rotating member 22 can rotate relative to the bracket 10 and the connecting member 23.

[0074] The second rotating mechanism 20' is the same as the first rotating mechanism 20, also including a first rotating member 21, a second rotating member 22, and a connecting member 23. One end of the first rotating member 21 and the second rotating member 22 are rotatably connected to the bracket 10, and the other end of the first rotating member 21 and the second rotating member 22 are rotatably connected to the connecting member 23. The first rotation axis C1 between the first rotating member 21 and the connecting member 23 is parallel and does not coincide with the second rotation axis C2 between the second rotating member 22 and the connecting member 23. The first rotating member 21, the second rotating member 22, and the connecting member 23 in the second rotating mechanism 20' can be referred to the first rotating member 21, the second rotating member 22, and the connecting member 23 in the first rotating mechanism 20, and will not be described again in this embodiment.

[0075] The support mechanism 30 in the folding device 1 is mainly used to support the component to be supported. As a driven mechanism 70 of the folding device 1, the support mechanism 30 can be restricted by the movement trajectory of other mechanisms to achieve the desired folding shape, thereby causing the component to be supported to bend and form the required shape. In this embodiment, the support mechanism 30 includes a first support member 31 and a second support member 31'. The first support member 31 supports the component to be supported and has a support surface 310 for supporting the component. Optionally, the component to be supported can abut against the support surface 310, or there can be a gap between the component and the support surface 310. The first support member 31 is rotatably connected to the connecting member 23, meaning the first support member 31 can rotate relative to the connecting member 23. The first support member 31 can also cooperate with the subsequent driven mechanism 70. The second support member 31' supports the component to be supported and has a support surface 310 for supporting the component. Optionally, the member to be supported may abut against the support surface 310, or there may be a gap between the member to be supported and the support surface 310. The second support member 31' is rotatably connected to the connecting member 23, that is, the second support member 31' can rotate relative to the connecting member 23. The second support member 31' can also cooperate with the subsequent driven mechanism 70.

[0076] This embodiment does not limit the shape, structure, material, or other parameters of the first support member 31 and the second support member 31', as long as the first support member 31 and the second support member 31' can support the member to be supported and rotatably connect the connecting member 23 and the driven member 71.

[0077] The driven mechanism 70 plays an auxiliary role in the folding device 1, mainly controlling and driving the first support member 31 and the second support member 31' to move along a specific trajectory. The driven mechanism 70 includes a first driven member 71 and a second driven member 71' at least partially disposed on opposite sides of the bracket 10. One end of the first driven member 71 is slidably and rotatably connected to the bracket 10, meaning that the end of the first driven member 71 closer to the bracket 10 can slide and rotate relative to the bracket 10. The other end of the first driven member 71 is connected to both the connecting member 23 of the first connecting mechanism and the first support member 31. Firstly, the other end of the first driven member 71 is rotatably connected to the connecting member 23 of the first connecting mechanism, meaning that the end of the first driven member 71 furthest from the bracket 10 can rotate relative to the connecting member 23 of the first connecting mechanism. Secondly, the other end of the first driven member 71 slides and rotates relative to the first support member 31, meaning the first driven member 71 can slide and rotate relative to the first support member 31, or the first support member 31 can slide and rotate relative to the first driven member 71. One end of the second driven member 71' slides and rotates to be connected to the bracket 10, meaning the end of the second driven member 71' closer to the bracket 10 can slide and rotate relative to the bracket 10. The other end of the second driven member 71' is connected to both the connecting member 23 of the second rotating mechanism 20' and the second support member 31'. The other end of the second driven member 71' is rotatably connected to the connecting member 23 of the second rotating mechanism 20', meaning the end of the second driven member 71' furthest from the bracket 10 can rotate relative to the connecting member 23 of the second rotating mechanism 20'. Secondly, the other end of the second follower 71' also slides and rotates relative to the second support 31', that is, the second follower 71' can slide and rotate relative to the second support 31', or in other words, the second support 31' can slide and rotate relative to the second follower 71'.

[0078] This embodiment does not limit the shape, structure, material, or other parameters of the first driven member 71 and the second driven member 71', as long as the first driven member 71 and the second driven member 71' can achieve the above-mentioned connection relationship and play an auxiliary motion role. It should be noted here that the rotation mentioned above can be understood as the two moving members being able to perform circular motion around the axis of rotation. Sliding can be understood as the two moving members moving in parallel, with only a change in displacement and no change in angle. The fact that two moving members can both slide and rotate means that the two moving members have both a change in displacement and a change in angle, and this sliding and rotation can also be called rolling.

[0079] The folding device 1 provided in this embodiment includes a support mechanism 30, a driven mechanism 70, and two rotating mechanisms. The support mechanism 30, the driven mechanism 70, and the two rotating mechanisms constitute an integral mechanism, which is located on the side of the first support member 31 and the second support member 31' in the support mechanism 30 away from the support surface 310. In other embodiments, the folding device 1 includes two support mechanisms 30, two driven mechanisms 70, and four rotating mechanisms. Each support mechanism 30, one driven mechanism 70, and two rotating mechanisms constitute an integral mechanism. Both integral mechanisms are located on the side of the first support member 31 and the second support member 31' in the support mechanism 30 away from the support surface 310 and are spaced apart along the length direction of the first support member 31. Of course, in other embodiments, the folding device 1 may also include three or more support mechanisms 30, three or more driven mechanisms 70, and six or more rotating mechanisms. Each support mechanism 30, one driven mechanism 70, and two rotating mechanisms constitute an integral mechanism. The three or more integral mechanisms are all located on the side of the first support member 31 and the second support member 31' in the support mechanism 30 that is away from the support surface 310, and are spaced apart along the length direction of the first support member 31 and the second support member 31'.

[0080] Based on the above connection relationship, the folding device 1 can not only fold but also move according to a preset folding trajectory to obtain the desired folding shape. Specifically: when the folding device 1 is folded, the first driven member 71, the second driven member 71', and the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 and the second rotating mechanism 20' rotate, while the first driven member 71 and the second driven member 71' also slide, and the first support member 31 and the second support member 31' fold together; when the folding device 1 is unfolded, the first driven member 71, the second driven member 71', and the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 and the second rotating mechanism 20' rotate, while the first driven member 71 and the second driven member 71' also slide, and the first support member 31 and the second support member 31' unfold together.

[0081] The movement process of the aforementioned folding device 1 has multiple active and passive logical relationships. This application will illustrate one specific movement process as an example. When the folding device 1 is folded or unfolded, that is, when the connecting member 23 rotates relative to the support 10, since the first rotating member 21 and the second rotating member 22 are rotatably connected to the support 10, the connecting member 23 can drive the first rotating member 21 and the second rotating member 22 to rotate relative to the support 10. At the same time, since the first support member 31 is rotatably connected to the connecting member 23, when the connecting member 23 rotates relative to the support 10, the first support member 31 can rotate synchronously relative to the support 10. Furthermore, since the first driven member 71 is rotatably connected to the support 10, the connecting member 23 can drive the first driven member 71 to slide and roll relative to the support 10. When the first driven member 71 slides and rolls, it can cause the first driven member 71 to rotate relative to the connecting member 23, thereby driving the first support member 31 to slide and rotate relative to the first driven member 71, ultimately causing the first support member 31 and the second support member 31' to fold or unfold relative to each other.

[0082] Of course, in other embodiments, the active and passive relationships of the above-mentioned structural components can be reversed. For example, the first rotating component 21 and the second rotating component 22 can rotate relative to the bracket 10, thereby driving the connecting component 23 to rotate relative to the bracket 10. Such a motion process and principle should also fall within the protection scope of this application.

[0083] When the first support member 31 and the second support member 31' are parallel to each other, and the first support member 31 and the second support member 31' are located on opposite sides of the bracket 10, it can also be understood that when the first support member 31 is close to the first side 103 of the bracket 10, the first support member 31 and the second support member 31' are in a fully unfolded state. In other words, the folding device 1 is in an unfolded state. Figure 4 As shown. When the first support member 31 and the second support member 31' are parallel to each other, and both the first support member 31 and the second support member 31' are located on one side of the bracket 10, it can also be understood that both the first support member 31 and the second support member 31' are located on the top surface 101 of the bracket 10. At this time, the first support member 31 and the second support member 31' are in a completely folded state. In other words, the folding device 1 is in a folded state, as shown. Figure 8 As shown. When the first support member 31 and the second support member 31' fold together, that is, the process of the folding device 1 changing from the unfolded state to the folded state, can also be understood as from... Figures 4 to 8 During this process, the two connecting pieces 23 rotate relative to each other and move closer together, causing the first support piece 31 and the second support piece 31' to merge together, thereby achieving mutual approach and folding. When the first support piece 31 and the second support piece 31' unfold relative to each other, that is, when the folding device 1 moves from the folded state to the unfolded state, it can also be understood as moving from the folded state to the unfolded state. Figures 8 to 4During this process, the two connecting pieces 23 rotate relative to each other and move away from each other, causing the first support piece 31 and the second support piece 31' to separate from each other, so as to achieve mutual separation and unfolding.

[0084] When the folding device 1 is in the folded state, the first support member 31 and the second support member 31' together with the bracket 10 can form a receiving space 11 for receiving the part to be supported. The folding device 1 provided in this embodiment can make the cross-sectional shape of the part to be supported U-shaped or teardrop-shaped. This embodiment is only illustrated with the cross-sectional shape of the receiving space 11 being teardrop-shaped.

[0085] In summary, the folding device 1 provided in this embodiment, through the cooperation of the bracket 10, two rotating mechanisms, the support mechanism 30, and the driven mechanism 70, can realize the mutual folding and unfolding of the first support member 31 and the second support member 31', thus realizing the folding and unfolding function of the folding device 1. Furthermore, the first rotating member 21 and the second rotating member 22 are parallel to and do not coincide with the first rotation axis C1 and the second rotation axis C2 between them and the connecting member 23, respectively. This allows the folding device 1 to have a smaller length and its length dimension to remain unchanged while still enabling the normal movement of the first support member 31. This results in a compact structure for the folding device 1, reducing its size and the internal space occupied by the housing assembly 2 and the electronic device, which is beneficial for the layout of other structural components such as the motherboard or battery. Compared to the related technology where the connecting member 23 can slide relative to the rotating member, this also facilitates the miniaturization of the folding device 1. The aforementioned length direction of the folding device 1 can be understood as the arrangement direction of the first support member 31 and the second support member 31' relative to the bracket 10 when the folding device 1 is in the unfolded state.

[0086] In addition, the fact that the first rotation axis C1 and the second rotation axis C2 are parallel and do not coincide ensures that the connecting member 23 will not rotate relative to the first rotating member 21 and the second rotating member 22, thereby improving the stability of the folding device 1.

[0087] Optionally, when the folding device 1 is in the unfolded state, the support surface 310 of the first support member 31 may be coplanar with the top surface 101 of the bracket 10, so that the member to be supported can abut against the support surface 310 of the first support member 31 and the top surface 101 of the bracket 10. Of course, in other embodiments, the support mechanism 30 may also include a carrier member (not shown in the figure) disposed between the first support member 31 and the second support member 31'. The carrier member is mounted on the top surface 101 of the bracket 10 and also has a carrier surface for supporting the member to be supported. When the folding device 1 is in the unfolded state, the support surface 310 of the first support member 31 and the carrier surface are coplanar, so that the member to be supported can abut against the support surface 310 of the first support member 31 and the carrier surface.

[0088] Furthermore, the descriptions of various embodiments in this application are based on the accompanying illustrations, which are used to illustrate specific embodiments that can be implemented in this application. Directional terms used in this application, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying illustrations. Therefore, the directional terms used are for better and clearer explanation and understanding of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0089] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "set on" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. They can be mechanical connections. They can be direct connections or indirect connections through an intermediate medium, or they can be internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. For example, the various connections in this embodiment include both direct and indirect connections. For instance, the connection of two structural components includes a direct connection between the two structural components or a connection through a third or more other structural components. Connections also include both integrated and non-integrated connections. An integrated connection refers to two components being formed and connected as a single unit, while a non-integrated connection refers to A and B being formed and connected as separate units.

[0090] Please refer to this again. Figure 8 In this embodiment, the first support member 31 also rotates relative to the connector 23 of the first rotating mechanism 20, and the second support member 31' also rotates relative to the connector 23 of the second rotating mechanism 20', so that when the folding device 1 is in the folded state, the first support member 31 and the second support member 31' are both located on the same side of the bracket 10, and the distance between the first support member 31 and the second support member 31' at the end away from the bracket 10 is less than or equal to the distance between the first support member 31 and the second support member 31' at the end close to the bracket 10.

[0091] When the folding device 1 is in motion, in addition to sliding and rotating relative to the first driven member 71 and the second driven member 71', the first support member 31 and the second support member 31' can also drive the first support member 31 to rotate relative to the connecting member 23 by sliding and rotating relative to the first driven member 71 and the second driven member 71'. Specifically, the end of the first support member 31 and the second support member 31' near the bracket 10 can rotate towards the end near the connecting member 23, so that when the folding device 1 is in the folded state, the distance between the first support member 31 and the second support member 31' at the end away from the bracket 10 is smaller than the distance between the first support member 31 and the second support member 31' at the end near the bracket 10, that is, a gap with a smaller upper part and a larger lower part is formed between the first support member 31 and the second support member 31'. In other words, the receiving space 11 formed by the first support member 31, the second support member 31', and the bracket 10 is shaped like a teardrop, with a smaller top and a larger bottom, thus making the cross-sectional shape of the component to be supported teardrop-shaped. The specific design of the folding device 1 to restrict the movement trajectory of the first support member 31 and the second support member 31' and ultimately achieve the teardrop-shaped cross-sectional shape of the receiving space 11 will be described in detail below.

[0092] In other embodiments, the other ends of the first driven member 71 and the second driven member 71' may not drive the first support member 31 and the second support member 31' to rotate relative to the connecting member 23. In this case, when the folding device 1 is in the folded state, the first support member 31 and the second support member 31' and the bracket 10 can form a U-shaped receiving space 11. In other words, when the first support member 31 and the second support member 31' are in a fully folded state, the first support member 31 and the second support member 31' are both located on the same side of the bracket 10, and the distance between the first support member 31 and the second support member 31' at the end away from the bracket 10 is equal to the distance between the first support member 31 and the second support member 31' at the end closer to the bracket 10, that is, a gap of equal width is formed between the first support member 31 and the second support member 31'.

[0093] Next, this application will focus on describing the specific structure and positional relationship between the first rotating mechanism 20, the first support member 31, and the first driven member. Please refer to the following: Figures 9-11 , Figure 9 This is a schematic diagram of the cooperation between the first support member and the first driven member in one embodiment of this application. Figure 10 for Figure 9 The diagram shows the cooperation between the support member and the driven member from another perspective. Figure 11 for Figure 10The diagram shows an exploded view of the first support member and the first driven member. In this embodiment, the first support member 31 includes a support portion 313 and a rolling portion 314 disposed on the side of the support portion 313 near the connector 23. The rolling portion 314 is slidably and rotatably connected to the end of the first driven member 71 away from the bracket 10. The rolling portion 314 and the first driven member 71 are connected by a first rolling shaft 3141 and a first rolling groove 3140. The first rolling shaft 3141 is disposed on one of the rolling portion 314 and the first driven member 71, and the first rolling groove 3140 is disposed on the other of the rolling portion 314 and the first driven member 71.

[0094] The support portion 313 in the first support member 31 is used to support the member to be supported, and therefore the support portion 313 has a support surface 310 for supporting the member to be supported. The rolling portion 314 is provided on one side of the support portion 313, and the rolling portion 314 is used to slide and rotate connected to the other end of the first driven member 71. Specifically, in this embodiment, the support portion 313 is rectangular plate-shaped. In addition to having a support surface 310 and a non-support surface 311 opposite to the support surface 310, the support portion 313 also has a peripheral side surface 312 provided between the support surface 310 and the non-support surface 311. The rolling portion 314 is connected to the non-support surface 311 and the rolling portion 314 is closer to the connecting member 23 than the support portion 313, that is, the support portion 313 is farther away from the connecting member 23 than the rolling portion 314.

[0095] Furthermore, the support portion 313 and the rolling portion 314 can be either an integral structure or a separate structure. When the support portion 313 and the rolling portion 314 are an integral structure, they are manufactured in a single process; however, for ease of understanding, the support portion 313 and the rolling portion 314 are given different names. When the support portion 313 and the rolling portion 314 are separate structures, they are manufactured separately and then connected together using various methods. This embodiment is only illustrated illustratively using the example of a separate structure for the support portion 313 and the rolling portion 314.

[0096] Therefore, the aforementioned first support member 31 and the end of the first driven member 71 away from the bracket 10 are slidably and rotatably connected, which means that the rolling part 314 and the first driven member 71 are slidably and rotatably connected. Specifically, the rolling part 314 and the first driven member 71 are connected by a first rolling groove 3140 and a first rolling shaft 3141. The first rolling groove 3140 is provided on one of the rolling part 314 and the first driven member 71, and the first rolling shaft 3141 is provided on the other of the rolling part 314 and the first driven member 71. For example, when the first rolling groove 3140 is provided on the rolling part 314, the first rolling shaft 3141 is provided on the first driven member 71, and when the first rolling groove 3140 is provided on the first driven member 71, the first rolling shaft 3141 is provided on the rolling part 314. This embodiment is only illustrated with the first rolling groove 3140 being provided on the rolling part 314 and the first rolling shaft 3141 being provided on the first driven member 71. Specifically, the first rolling shaft 3141 is located on the side of the first driven member 71 opposite to the connecting member 23. The rolling part 314 is provided with a first rolling groove 3140. The first rolling shaft 3141 can rotate relative to the first rolling groove 3140, thereby causing the first support member 31 to rotate relative to the first driven member 71. At the same time, the first rolling shaft 3141 can also slide within the first rolling groove 3140, thereby causing the first support member 31 to slide relative to the first driven member 71, so that the first support member 31 can slide and rotate relative to the first driven member 71. Of course, in other embodiments, the first rolling groove 3140 may also be provided on the first driven member 71, and the first rolling shaft 3141 may be mounted on the rolling part 314. Optionally, the first rolling shaft 3141 may include, but is not limited to, a pin.

[0097] Furthermore, the first rolling shaft 3141 and the rolling part 314 or the first driven member 71 can be fixedly connected or rotatably connected. For example, in this embodiment, the first rolling shaft 3141 is disposed on the first driven member 71. The first rolling shaft 3141 can be fixedly disposed on the first driven member 71 so that the first rolling shaft 3141 and the first driven member 71 remain relatively stationary, thereby allowing the first rolling groove 3140 to slide and rotate relative to the first rolling shaft 3141. Alternatively, the first rolling shaft 3141 can also be rotatably connected to the first driven member 71 so that the first rolling shaft 3141 and the first driven member 71 remain relatively rotating, thus still allowing the first rolling groove 3140 to slide and rotate relative to the first rolling shaft 3141. Optionally, when the first rolling shaft 3141 is fixedly disposed on the first driven member 71, the first rolling shaft 3141 and the first driven member 71 can be an integral structure or a separate structure. When the first rolling shaft 3141 and the first driven member 71 are an integral structure, they are manufactured in a single process. However, for ease of understanding, the first rolling shaft 3141 and the first driven member 71 are given different names. When the first rolling shaft 3141 and the first driven member 71 are separate structures, they are manufactured separately and then connected together using various methods. This embodiment is only used to illustrate the case where the first rolling shaft 3141 and the first driven member 71 are separate structures.

[0098] It is worth noting that this embodiment and the following description only illustrate half of the structure of the folding device 1. In other words, only the right half of the structure of the folding device 1 is illustrated. For example, this embodiment only illustrates one first support member 31 and one connector 23 located on the right side of the bracket 10. As for the other first support member 31 and the other connector 23 located on the left side of the bracket 10, they can be understood in the same way as the first support member 31 and the connector 23 in this embodiment. This embodiment will not be described in detail here.

[0099] Please refer to this as well. Figures 12-13 , Figure 12 This is a partial structural diagram of the folding device in the unfolded state according to one embodiment of this application. Figure 13 This is a partial structural diagram of the folding device in a folded state according to another embodiment of this application. In this embodiment, the support portion 313 has a support surface 310 for supporting the component to be supported, and the first rolling groove 3140 has a first limiting end 3140a and a second limiting end 3140b opposite to each other. The first limiting end 3140a is farther away from the bracket 10 than the second limiting end 3140b, and the first limiting end 3140a is farther away from the support surface 310 than the second limiting end.

[0100] When the first support member 31 and the second support member 31' are in a fully unfolded state, the first rolling shaft 3141 is positioned at the first limiting end 3140a. When the first support member 31 and the second support member 31' are in a fully folded state, the first rolling shaft 3141 is positioned at the second limiting end 3140b.

[0101] The first rolling groove 3140 has two oppositely arranged ends: a first limiting end 3140a and a second limiting end 3140b. Since the rolling shaft slides within the first rolling groove 3140, the sidewalls 52 of the first limiting end 3140a and the second limiting end 3140b can be used to restrict the sliding of the rolling shaft, causing it to stop sliding when it reaches the first limiting end 3140a and the second limiting end 3140b, preventing it from continuing to slide. Figure 12 As shown, the first limiting end 3140a is farther away from the bracket 10 than the second limiting end 3140b, meaning the first limiting end 3140a is more to the right than the second limiting end 3140b. Simultaneously, the first limiting end 3140a is farther away from the support surface 310 than the second limiting end 3140b, meaning the first limiting end 3140a is lower than the second limiting end 3140b. Therefore, the first limiting end 3140a is located in the lower right position, while the second limiting end 3140b is located in the upper left position.

[0102] During the entire movement of the folding device 1, when the first support member 31 and the second support member 31' are fully unfolded (i.e., when the folding device 1 is in the unfolded state), the first rolling shaft 3141 is positioned at the first limiting end 3140a to prevent the first support member 31 from folding back and damaging the subsequent support member. When the first support member 31 and the second support member 31' are fully folded (i.e., when the folding device 1 is in the folded state), the first rolling shaft 3141 is positioned at the second limiting end 3140b to prevent the first support member 31 from further bending and damaging the subsequent support member. In other words, when the first support member 31 is fully unfolded, the first rolling shaft 3141 is located at the lower right; when the first support member 31 is fully folded, the first rolling shaft 3141 is located at the upper left.

[0103] Therefore, during the process of the folding device 1 changing from the unfolded state to the folded state, the connecting member 23 can drive the first driven member 71 to slide and rotate relative to the support 10 when it rotates relative to the support 10. At this time, the first driven member 71 can also rotate relative to the connecting member 23 when it slides and rotates, thereby causing the position of the first rolling shaft 3141 to change, so that it can move from the first limiting end 3140a to the second limiting end 3140b, or in other words, the first rolling shaft 3141 moves from the lower right to the upper left in the first rolling groove 3140. At this time, the first rolling shaft 3141 will contact the side wall 52 of the first rolling groove 3140, causing the first support member 31 to slide and rotate relative to the first driven member 71, thereby driving the first support member 31 to rotate relative to the connecting member 23, so that the first support member 31 and the second support member 31' cooperate with the support 10 to form a teardrop shape.

[0104] Please refer to this again. Figures 12-13 In this embodiment, the first rolling groove 3140 also has a first connecting portion 3140c that connects the first limiting end 3140a and the second limiting end 3140b. From the first limiting end 3140a to the first connecting portion 3140c and then to the second limiting end 3140b, the distance between the first rolling groove 3140 and the support surface 310 gradually decreases.

[0105] The first rolling groove 3140 is a groove with a certain length. Therefore, in addition to the first limiting end 3140a and the second limiting end 3140b, the first rolling groove 3140 also has a first connecting portion 3140c that connects the first limiting end 3140a and the second limiting end 3140b. The rolling shaft is located in the first connecting portion 3140c in all states except the unfolded state and the folded state. In this embodiment, the distance of the first connecting portion 3140c from the support surface 310 gradually decreases from the first limiting end 3140a to the second limiting end 3140b. It can also be understood that the shape of the first connecting portion 3140c is a straight line. In this way, the first support member 31 can rotate relative to the connecting member 23 to form a teardrop shape during the entire movement of the first rolling shaft 3141, thereby reducing the length of the first connecting portion 3140c.

[0106] Of course, in other embodiments, the shape of the first connecting portion 3140c can also be arc-shaped or other shapes, as long as the positions of the first limiting end 3140a and the second limiting end 3140b satisfy the above-mentioned position limitations.

[0107] In other embodiments, when the first support member 31 and the second support member 31' are in the fully unfolded state, the first rolling shaft 3141 may also be located within the first connecting portion 3140c; when the first support member 31 and the second support member 31' are in the fully folded state, the first rolling shaft 3141 is located within the second limiting end 3140b. During the process of the folding device 1 moving from the unfolded state to the folded state, the first rolling shaft 3141 first moves from the first connecting portion 3140c to the first limiting end 3140a, and then moves from the first limiting end 3140a to the second limiting end 3140b.

[0108] Please refer to this as well. Figures 12-14 , Figure 14 This is a schematic diagram illustrating the engagement of the first driven member, the first support member, and the connecting member of the first rotating mechanism in one embodiment of this application. In this embodiment, the third rotation axis C3 between the first driven member 71 and the connecting member 23 of the first rotating mechanism 20 is farther away from the bracket 10 than the fourth rotation axis C4 between the first driven member 71 and the rolling part 314.

[0109] As can be seen from the above, the first driven member 71 can rotate relative to the connecting member 23 of the first rotating mechanism 20. Therefore, there is a third rotation axis C3 between the first driven member 71 and the connecting member 23 of the first rotating mechanism 20 (e.g., Figure 14 (As shown in C3). Similarly, the first driven member 71 and the rolling part 314 can also rotate relative to each other, therefore the first driven member 71 and the rolling part 314 have a fourth rotation axis C4 (as shown in C3). Figure 14 (As shown in C4). In this embodiment, the third rotation axis C3 is positioned further away from the bracket 10 than the fourth rotation axis C4. In other words, the third rotation axis C3 is further outward than the fourth rotation axis C4. This can also be understood as the connection between the first driven member 71 and the first support member 31 being closer to the bracket 10. This increases the length of the support plate and reduces the gap between the support plate and the bracket 10, thereby allowing for the support of more members to be supported in subsequent support operations and increasing the area of ​​the support surface 310.

[0110] In other embodiments, the third rotation axis C3 is closer to the support surface 310 than the fourth rotation axis C4, meaning the third rotation axis C3 is higher and the fourth rotation axis C4 is lower. This increases the size of the first connecting portion 3140c, allowing the first rolling shaft 3141 to roll more smoothly and slowly relative to the first driven member 71 when it rolls within the first rolling groove 3140.

[0111] Please refer to this as well. Figures 15-16 , Figure 15 This is a schematic diagram showing the connection between the first driven member and the first rotating mechanism in one embodiment of this application. Figure 16 for Figure 15 The diagram shows an exploded view of the connection between the first driven member and the first rotating mechanism. In this embodiment, the end of the first driven member 71 away from the bracket 10 is connected to the connection 23 of the first rotating mechanism 20 via a first rotating shaft 7110 and a first rotating hole 7111. The first rotating shaft 7110 is located in one of the first driven member 71 and the connection 23 of the first rotating mechanism 20, and the first rotating hole 7111 is located in the other of the connection 23.

[0112] As mentioned above, the first driven member 71 can rotate relative to the connecting member 23 of the first rotating mechanism 20. In this embodiment, the first driven member 71 and the connecting member 23 of the first rotating mechanism 20 are connected via a first rotating shaft 7110 and a first rotating hole 7111. The axis of the first rotating shaft 7110 coincides with the axis of the first rotating hole 7111, and the axis of the first rotating shaft 7110 coincides with the third rotating axis C3 between the first driven member 71 and the connecting member 23 of the first rotating mechanism 20, thereby achieving a rotatable connection between the first driven member 71 and the connecting member 23 of the first rotating mechanism 20. For example, when the first rotating shaft 7110 is located on the first driven member 71, the first rotating hole 7111 is located on the connecting member 23 of the first rotating mechanism 20; or when the first rotating shaft 7110 is located on the connecting member 23 of the first rotating mechanism 20, the first rotating hole 7111 is located on the first driven member 71. This embodiment is only illustrated by the example of a first rotating shaft 7110 being disposed on a first driven member 71 and a first rotating hole 7111 being disposed on a connector 23 of a first rotating mechanism 20. Specifically, the first rotating shaft 7110 protrudes from at least one side of the first driven member 71 near the connector 23 of the first rotating mechanism 20. The connector 23 of the first rotating mechanism 20 has a first rotating hole 7111 on the side near the first driven member 71. The first rotating shaft 7110 is inserted into the first rotating hole 7111 so that the first rotating shaft 7110 can rotate within the first rotating hole 7111, thereby causing the first driven member 71 to rotate relative to the connector 23 of the first rotating mechanism 20.

[0113] Of course, in other embodiments, the first rotating shaft 7110 may also be provided on the connecting member 23 of the first rotating mechanism 20, and the first rotating hole 7111 may be provided on the first driven member 71.

[0114] It is worth noting that the first rotating hole 7111 mentioned in this embodiment can be a through hole or a blind hole. A through hole refers to the first rotating hole 7111 penetrating both opposite surfaces of the structural member, while a blind hole refers to the first rotating hole 7111 penetrating only one surface of the structural member. Therefore, a blind hole can also be called a groove.

[0115] Furthermore, the first rotating shaft 7110 and the connecting member 23 of the first driven member 71 or the first rotating mechanism 20 can be either fixedly connected or rotatably connected. For example, in this embodiment, the first rotating shaft 7110 is disposed on the first driven member 71. The first rotating shaft 7110 can be fixedly disposed on the first driven member 71 so that the first rotating shaft 7110 and the first driven member 71 remain relatively stationary. The first rotating shaft 7110 is inserted into the first rotating hole 7111 and rotates relative to the first rotating hole 7111, thereby causing the first driven member 71 to rotate relative to the connecting member 23 of the first rotating mechanism 20. Alternatively, the first rotating shaft 7110 can also be rotatably connected to the first driven member 71, so that the first rotating shaft 7110 and the first driven member 71 remain relatively rotating. In this way, the first rotating shaft 7110 can still rotate within the first rotating hole 7111, thereby causing the first driven member 71 to rotate relative to the connecting member 23 of the first rotating mechanism 20. For example, the first follower 71 has a first receiving hole 7112, the first rotating shaft 7110 passes through the first receiving hole 7112, and at least one end of the first rotating shaft 7110 protrudes from the first follower 71.

[0116] Optionally, when the first rotating shaft 7110 is fixed to the first driven member 71, the first rotating shaft 7110 and the first driven member 71 can be an integral structure or a separate structure. When the first rotating shaft 7110 and the first driven member 71 are an integral structure, they are manufactured in one process; however, for ease of understanding, the first rotating shaft 7110 and the first driven member 71 are given different names. When the first rotating shaft 7110 and the first driven member 71 are separate structures, they are manufactured separately and then connected together by various methods, such as insertion. This embodiment is only illustrated with the example of the first rotating shaft 7110 and the first driven member 71 being a separate structure.

[0117] Please refer to this as well. Figures 17-18 , Figure 17 This is a schematic diagram of the cooperation between the first driven member and the bracket in one embodiment of this application. Figure 18 for Figure 17 The diagram shows an exploded view of the first driven member and the support. In this embodiment, the end of the first driven member 71 near the support 10 is connected to the support 10 via a second rolling shaft 7101 and a second rolling groove 7100. The second rolling shaft 7101 is provided in one of the first driven member 71 and the support 10, and the second rolling groove 7100 is provided in the other of the first driven member 71 and the support 10.

[0118] As mentioned above, the first driven member 71 can also slide and rotate relative to the bracket 10. Therefore, the first driven member 71 and the bracket 10 are connected by a second rolling groove 7100 and a second rolling shaft 7101. The second rolling groove 7100 is provided on one of the first driven member 71 and the bracket 10, and the second rolling shaft 7101 is provided on the other. For example, when the second rolling groove 7100 is provided on the first driven member 71, the second rolling shaft 7101 is provided on the bracket 10; when the second rolling groove 7100 is provided on the bracket 10, the second rolling shaft 7101 is provided on the first driven member 71. This embodiment is only illustrated with the second rolling groove 7100 provided on the bracket 10 and the second rolling shaft 7101 provided on the first driven member 71. Specifically, the second rolling groove 7100 is disposed on the second side surface 104 of the bracket 10, and the first driven member 71 is provided with a second rolling shaft 7101. The second rolling shaft 7101 can rotate relative to the second rolling groove 7100, thereby causing the first driven member 71 to rotate relative to the bracket 10. At the same time, the second rolling shaft 7101 can also slide within the second rolling groove 7100, thereby causing the first driven member 71 to slide relative to the bracket 10, so that the first driven member 71 can slide and rotate relative to the bracket 10. Of course, in other embodiments, the second rolling shaft 7101 may also be disposed on the second side surface 104 of the bracket 10, and the second rolling groove 7100 may be mounted on the first driven member 71. Optionally, the second rolling shaft 7101 may include, but is not limited to, a pin.

[0119] Furthermore, the second rolling shaft 7101 and the first driven member 71 or the bracket 10 can be either fixedly connected or rotatably connected. For example, in this embodiment, the second rolling shaft 7101 is disposed on the first driven member 71. The second rolling shaft 7101 can be fixedly disposed on the first driven member 71 so that the second rolling shaft 7101 and the first driven member 71 remain relatively stationary, thereby allowing the second rolling groove 7100 to slide and rotate relative to the second rolling shaft 7101. Alternatively, the second rolling shaft 7101 can also be rotatably connected to the first driven member 71, so that the second rolling shaft 7101 and the first driven member 71 remain relatively rotating, thus still allowing the second rolling groove 7100 to slide and rotate relative to the second rolling shaft 7101. Optionally, when the second rolling shaft 7101 is fixedly disposed on the first driven member 71, the second rolling shaft 7101 and the first driven member 71 can be an integral structure or a separate structure. When the second rolling shaft 7101 and the first driven member 71 are an integral structure, they are manufactured in a single process. However, for ease of understanding, the second rolling shaft 7101 and the first driven member 71 are given different names. When the second rolling shaft 7101 and the first driven member 71 are separate structures, they are manufactured separately and then connected together using various methods. This embodiment is only used to illustrate the case where the second rolling shaft 7101 and the first driven member 71 are separate structures.

[0120] Please refer to this again. Figures 12-13 ,as well as Figures 17-18 In this embodiment, the first support member 31 has a support surface 310 for supporting the member to be supported, and the second rolling groove 7100 is provided with a third limiting end 7100a and a fourth limiting end 7100b. When the first support member 31 and the second support member 31' are in a fully extended state, the third limiting end 7100a is farther away from the first support member 31 than the fourth limiting end 7100b, and the third limiting end 7100a is farther away from the support surface 310 than the fourth limiting end.

[0121] When the first support member 31 and the second support member 31' are in a fully unfolded state, the second rolling shaft 7101 is positioned at the third limiting end 7100a. When the first support member 31 and the second support member 31' are in a fully folded state, the second rolling shaft 7101 is positioned at the fourth limiting end 7100b.

[0122] The second rolling groove 7100 has two oppositely arranged ends: a third limiting end 7100a and a fourth limiting end 7100b. Since the second rolling shaft 7101 slides within the second rolling groove 7100, the sidewalls 52 of the third limiting end 7100a and the fourth limiting end 7100b can be used to restrict the sliding of the second rolling shaft 7101, causing it to stop sliding when it reaches the third limiting end 7100a and the fourth limiting end 7100b, preventing it from continuing to slide. Figure 12 As shown, when the first support member 31 and the second support member 31' are in a fully extended state, the third limiting end 7100a is farther away from the first support member 31 than the fourth limiting end 7100b, that is, the third limiting end 7100a is more to the left than the fourth limiting end 7100b. At the same time, the third limiting end 7100a is farther away from the support surface 310 than the fourth limiting end 7100b, that is, the third limiting end 7100a is more lower than the fourth limiting end 7100b. Therefore, the third limiting end 7100a is located in the lower left position, while the fourth limiting end 7100b is located in the upper right position.

[0123] During the entire movement of the folding device 1, when the first support member 31 and the second support member 31' are fully unfolded (i.e., when the folding device 1 is in the unfolded state), the second rolling shaft 7101 is positioned at the third limiting end 7100a to prevent the first support member 31 from folding back and damaging the subsequent support member. When the first support member 31 and the second support member 31' are fully folded (i.e., when the folding device 1 is in the folded state), the second rolling shaft 7101 is positioned at the fourth limiting end 7100b to prevent the first support member 31 from further bending and damaging the subsequent support member. In other words, when the first support member 31 is fully unfolded, the second rolling shaft 7101 is located at the lower left; when the first support member 31 is fully folded, the second rolling shaft 7101 is located at the upper right.

[0124] Therefore, during the process of the folding device 1 changing from the unfolded state to the folded state, when the connecting member 23 of the first rotating mechanism 20 rotates relative to the bracket 10, it can drive the first driven member 71 to slide and rotate relative to the bracket 10, so that the second rolling shaft 7101 moves from the lower left to the upper right in the second rolling groove 7100. At this time, the second rolling shaft 7101 will contact the side wall 52 of the second rolling groove 7100, thereby driving the first driven member 71 to rotate relative to the bracket 10, causing the other end of the first driven member 71 to rotate relative to the connecting member 23 of the first rotating mechanism 20, and then causing the second rolling shaft 7101 on the other end of the first driven member 71 to move from the third limiting end 7100a to the fourth limiting end 7100b, thereby causing the first support member 31 to rotate relative to the connecting member 23 of the first rotating mechanism 20, so that the first support member 31 and the second support member 31' cooperate with the bracket 10 to form a teardrop-shaped receiving space 11. When the folding device 1 changes from the folded state to the unfolded state, the above-mentioned components all move in the opposite direction, which will not be described in detail here.

[0125] Please refer to this as well. Figures 19-20 , Figure 19 This is a partial structural diagram of the folding device in the unfolded state according to another embodiment of this application. Figure 20 This is a partial structural diagram of the folding device in a folded state according to another embodiment of this application. In one embodiment, the axis of the second rolling shaft 7101 can be positioned closer to the bottom surface 102 of the support 10 than the axis between the two rotating members and the support 10. The first rotating member 21 of the first rotating mechanism 20 can rotate relative to the support 10, therefore, there is a first rotation axis C11 between the first rotating member 21 of the first rotating mechanism 20 and the support 10. The second rotating member 22 of the first rotating mechanism 20 can rotate relative to the support 10, therefore, there is a second rotation axis C22 between the second rotating member 22 of the first rotating mechanism 20 and the support 10. The first driven member 71 can roll relative to the support 10, therefore, there is a third rotation axis C33 with a variable position between the first driven member 71 and the support 10. In this embodiment, the third rotation axis C33 can be positioned closer to the bottom surface 102 of the support 10 than the first rotation axis C11 and the second rotation axis C22, that is, in Figure 19In the vertical direction, the third rotating shaft 2210 has its rotation axis lower, while the first rotating shaft C11 and the second rotating shaft C22 have their axes higher. Thus, when the connecting member 23 of the first rotating mechanism 20 rotates relative to the support 10, it can drive the first rotating member 21, the second rotating member 22, and the first driven member 71 of the first rotating mechanism 20 to rotate relative to the support 10. Furthermore, since the axes of the two rotating members are higher, the displacement difference generated during rotation can be compensated by the relative sliding of the third rotating shaft C33 through the connecting member 23 of the first rotating mechanism 20. This allows the second rolling shaft 7101 to move from the third limiting end 7100a to the fourth limiting end 7100b. Optionally, during the process of the folding device 1 from the unfolded state to the folded state, when the connecting member 23 of the first rotating mechanism 20 on the right rotates, the first rotating member 21, the second rotating member 22, and the first driven member 71 of the first rotating mechanism 20 rotate counterclockwise, and the second rolling shaft 7101 provided on the first driven member 71 slides upward and to the right.

[0126] Please refer to this again. Figures 19-20In another embodiment, the two rotating members have corresponding axes with the support 10, and the two rotating members have corresponding centerlines with the connecting member 23 of the first rotating mechanism 20. The distance between the axis and centerline of each rotating member relative to its two ends changes in different states. For example, when the folding device 1 is in the unfolded state, the horizontal projection distance between the axis and centerline of the first rotating member 21 of the first rotating mechanism 20 relative to its two ends (i.e., the first rotation axis C11 and the first rotation centerline C1) is L1. When the folding device 1 is in the folded state, the vertical projection distance between the axis and centerline of the first rotating member 21 of the first rotating mechanism 20 relative to its two ends is L2, and L2>L1. Due to the increase in distance, while the first driven member 71 rotates, the connecting member 23 of the first rotating mechanism 20 can also pull the first driven member 71 to slide relative to the support 10 from the lower left to the upper right, thereby allowing the first driven member 71 to slide and rotate relative to the support 10. The same understanding applies to the second rotating member 22 of the first rotating mechanism 20, which will not be elaborated here in this embodiment. Optionally, when the folding device 1 is in the unfolded state, the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 are inclined downward in the horizontal direction, so their projection distance in the horizontal direction is small. During the movement of the folding device 1, in addition to rotating relative to the support 10, the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 can also rotate relative to the connecting member 23 of the first rotating mechanism 20. For example, the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 located on the right side of the support 10 can rotate counterclockwise relative to the connecting member 23 of the first rotating mechanism 20, thereby changing their projection distance in the vertical direction, increasing the projection distance, and thus allowing the first driven member 71 to slide and rotate relative to the support 10.

[0127] Please refer to this again. Figures 12-13 In this embodiment, the second rolling groove 7100 also has a second connecting portion 7100c that connects the third limiting end 7100a and the fourth limiting end 7100b, and the second connecting portion 7100c protrudes in a direction away from the support surface 310.

[0128] The second rolling groove 7100 is a groove of a certain length. Therefore, in addition to the third limiting end 7100a and the fourth limiting end 7100b, the second rolling groove 7100 also has a second connecting portion 7100c that connects the third limiting end 7100a and the fourth limiting end 7100b. The second rolling shaft 7101 is located within the second connecting portion 7100c in all states except the unfolded and folded states. In this embodiment, the second connecting portion 7100c can be made to protrude in a direction away from the support surface 310, that is, the shape of the second connecting portion 7100c is arc-shaped, and the arc protrudes downward. This makes the movement of the first driven member 71 smoother, and thus makes the movement of the first support member 31 smoother, thereby effectively protecting the member to be supported. Of course, in other embodiments, the shape of the second connecting portion 7100c can also be a straight line or other shapes, as long as the third limiting end 7100a and the fourth limiting end 7100b satisfy the above-mentioned position limitations.

[0129] Please refer to Figure 21 , Figure 21 for Figure 1 The diagram shows a top view of the folding device. In this embodiment, the two rotating mechanisms 20, the first support member 31 and the second support member 31', and the first follower member 71 and the second follower member 71' can all be arranged symmetrically with respect to the bracket 10, thereby simplifying the structure of the folding device 1 and improving the appearance consistency of the folding device 1.

[0130] Please refer to this again. Figure 12 In this embodiment, the first rotation axis C1 is farther away from the bracket 10 than the second rotation axis C2. As mentioned above, the first rotation axis C1 between the first rotating member 21 and the connecting member 23 of the first rotating mechanism 20 can be parallel to the second rotation axis C2 between the second rotating member 22 and the connecting member 23 of the first rotating mechanism 20, thereby preventing the bracket 10 from rotating relative to the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20, and ensuring the stability of the bracket 10. This application also provides different embodiments to make the first rotation axis C1 parallel to the second rotation axis C2. Specifically, in this embodiment, the first rotation axis C1 is farther away from the bracket 10 than the second rotation axis C2; in other words, in… Figure 12 In the horizontal direction, the first rotation axis C1 is further out, and the second rotation axis C2 is further in, thus achieving parallelism between the first rotation axis C1 and the second rotation axis C2. In other embodiments, the first rotation axis C1 can also be positioned closer to the bracket 10 than the second rotation axis C2.

[0131] Please refer to this again. Figure 12In this embodiment, the first support member 31 has a support surface 310, and the first rotation axis C1 is closer to the support surface 310 than the second rotation axis C2.

[0132] In addition to allowing the first rotation axis C1 to be positioned further outward in the horizontal direction, this embodiment also allows the first rotation axis C1 to be closer to the support surface 310 than the second rotation axis C2. In other words, in Figure 12 In the vertical direction, the first rotation axis C1 is positioned higher, and the second rotation axis C2 is positioned lower, thereby further increasing the distance between the two rotation axis lines. This increased distance improves the stability of the connecting member 23 of the first rotation mechanism 20, preventing it from rotating relative to the first rotating member 21 and the second rotating member 22 of the first rotation mechanism 20. Furthermore, positioning the first rotation axis line C1 closer to the upper right and the second rotation axis line C2 closer to the lower left allows for a reduction in the size of the folding device 1 while maintaining the same distance between the two axis lines, further miniaturizing the folding device 1.

[0133] Furthermore, the first driven member 71, the first rotating member 21 of the first rotating mechanism 20, and the second rotating member 22 of the first rotating mechanism 20, located on the same side of the support 10, can be stacked along the centerline of the support 10. The positional relationship between the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20, for example, which of the two rotating members 21 and 22 is closer to the first driven member 71, is not limited in this embodiment. This embodiment is only illustrated by the fact that the first rotating member 21 of the first rotating mechanism 20 is farther away from the first driven member 71 than the second rotating member 22 of the first rotating mechanism 20.

[0134] Please refer to this as well. Figures 22-23 , Figure 22 This is a schematic diagram showing the cooperation of the first rotating component, the second rotating component, and the connecting component of the first rotating mechanism in one embodiment of this application. Figure 23 for Figure 22The diagram shows an exploded view of the first rotating component, the second rotating component, and the connecting component of the first rotating mechanism. In this embodiment, the end of the first rotating component 21 of the first rotating mechanism 20 away from the support 10 is connected to the connecting component 23 of the first rotating mechanism 20 via a second rotating shaft 2110 and a second rotating hole 2111. The second rotating shaft 2110 is located in one of the first rotating component 21 and the connecting component 23 of the first rotating mechanism 20, and the second rotating hole 2111 is located in the other of the first rotating component 21 and the connecting component 23 of the first rotating mechanism 20. The end of the second rotating member 22 of the first rotating mechanism 20 away from the bracket 10 is connected to the connecting member 23 of the first rotating mechanism 20 through a third rotating shaft 2210 and a third rotating hole 2211. The third rotating shaft 2210 is located in one of the second rotating member 22 and the connecting member 23 of the first rotating mechanism 20, and the third rotating hole 2211 is located in the other of the second rotating member 22 and the connecting member 23 of the first rotating mechanism 20.

[0135] One end of the first rotating component 21 of the first rotating mechanism 20, which is connected to the second rotating component 22 and the connecting component 23 of the first rotating mechanism 20, can be a combination of a rotating shaft and a rotating hole. Specifically, the first rotating component 21 and the connecting component 23 of the first rotating mechanism 20 can be connected by a second rotating shaft 2110 and a second rotating hole 2111. The axis of the second rotating shaft 2110 coincides with the axis of the second rotating hole 2111, and the axis of the second rotating shaft 2110 coincides with the first rotating axis C1 between the first rotating component 21 and the connecting component 23 of the first rotating mechanism 20, thereby realizing the rotatable connection between the first rotating component 21 and the connecting component 23 of the first rotating mechanism 20. For example, when the second rotating shaft 2110 is disposed on the connecting member 23 of the first rotating mechanism 20, the second rotating hole 2111 is disposed on the first rotating member 21 of the first rotating mechanism 20; or when the second rotating shaft 2110 is disposed on the first rotating member 21 of the first rotating mechanism 20, the second rotating hole 2111 is disposed on the connecting member 23 of the first rotating mechanism 20. This embodiment is only illustrated with the example of the second rotating shaft 2110 being disposed on the first rotating member 21 of the first rotating mechanism 20 and the second rotating hole 2111 being disposed on the connecting member 23 of the first rotating mechanism 20. Specifically, the second rotating shaft 2110 protrudes from opposite sides of the first rotating member 21 of the first rotating mechanism 20, and the connecting member 23 of the first rotating mechanism 20 is provided with the second rotating hole 2111. The second rotating shaft 2110 is inserted into the second rotating hole 2111 so that the second rotating shaft 2110 can rotate within the second rotating hole 2111, thereby causing the first rotating member 21 of the first rotating mechanism 20 to rotate relative to the connecting member 23 of the first rotating mechanism 20. Of course, in other embodiments, the second rotating shaft 2110 may also be provided on the connecting member 23 of the first rotating mechanism 20, and the second rotating hole 2111 may be provided on the opposite sides of the first rotating member 21 of the first rotating mechanism 20.

[0136] It is worth noting that the second rotating hole 2111 mentioned in this embodiment can be a through hole or a blind hole. A through hole refers to the second rotating hole 2111 penetrating both opposite surfaces of the structural member, while a blind hole refers to the second rotating hole 2111 penetrating only one surface of the structural member. Therefore, a blind hole can also be called a groove.

[0137] Furthermore, the connection between the second rotating shaft 2110 and the connecting member 23 of the first rotating mechanism 20 or the first rotating member 21 of the first rotating mechanism 20 can be fixed or rotatably connected. For example, in this embodiment, the second rotating shaft 2110 is disposed on the first rotating member 21 of the first rotating mechanism 20. The second rotating shaft 2110 can be fixedly disposed on the first rotating member 21 of the first rotating mechanism 20 so that the second rotating shaft 2110 and the first rotating member 21 of the first rotating mechanism 20 remain relatively stationary. The second rotating shaft 2110 is inserted into the second rotating hole 2111 and rotates relative to the second rotating hole 2111, thereby causing the connecting member 23 of the first rotating mechanism 20 to rotate relative to the first rotating member 21 of the first rotating mechanism 20. Alternatively, the second rotating shaft 2110 can also be rotatably connected to the first rotating member 21 of the first rotating mechanism 20, so that the second rotating shaft 2110 and the first rotating member 21 of the first rotating mechanism 20 maintain relative rotation. In this way, the second rotating shaft 2110 can still rotate within the second rotating hole 2111, thereby causing the connecting member 23 of the first rotating mechanism 20 to rotate relative to the first rotating member 21 of the first rotating mechanism 20. For example, the first rotating member 21 of the first rotating mechanism 20 has a second receiving hole 2112 passing through its opposite sides, the second rotating shaft 2110 passes through the second receiving hole 2112, and both opposite ends of the second rotating shaft 2110 protrude from the opposite sides of the first rotating member 21 of the first rotating mechanism 20.

[0138] Optionally, when the second rotating shaft 2110 is fixed to the first rotating component 21 of the first rotating mechanism 20, the second rotating shaft 2110 and the first rotating component 21 of the first rotating mechanism 20 can be an integral structure or a separate structure. When the second rotating shaft 2110 and the first rotating component 21 of the first rotating mechanism 20 are an integral structure, they are manufactured in one process; however, for ease of understanding, the second rotating shaft 2110 and the first rotating component 21 of the first rotating mechanism 20 are given different names. When the second rotating shaft 2110 and the first rotating component 21 of the first rotating mechanism 20 are separate structures, they are manufactured separately and then joined together by various methods, such as insertion. This embodiment is only illustrated using the example of the second rotating shaft 2110 and the first rotating component 21 of the first rotating mechanism 20 being separate structures.

[0139] Similarly, the second rotating member 22 of the first rotating mechanism 20 and the connecting member 23 of the first rotating mechanism 20 can be connected by a third rotating shaft 2210 and a third rotating hole 2211. The axis of the third rotating shaft 2210 coincides with the axis of the third rotating hole 2211, and the axis of the third rotating shaft 2210 coincides with the second rotating axis C2 between the second rotating member 22 and the connecting member 23 of the first rotating mechanism 20, thereby realizing the rotatable connection between the second rotating member 22 and the connecting member 23 of the first rotating mechanism 20. For example, when the third rotating shaft 2210 is provided on the connecting member 23 of the first rotating mechanism 20, the third rotating hole 2211 is provided on the second rotating member 22 of the first rotating mechanism 20, or when the third rotating shaft 2210 is provided on the second rotating member 22 of the first rotating mechanism 20, the third rotating hole 2211 is provided on the connecting member 23 of the first rotating mechanism 20. This embodiment is only illustrated by the example of a third rotating shaft 2210 being disposed on the second rotating member 22 of the first rotating mechanism 20 and a third rotating hole 2211 being disposed on the connecting member 23 of the first rotating mechanism 20. Specifically, the third rotating shaft 2210 protrudes from opposite sides of the second rotating member 22 of the first rotating mechanism 20, and the connecting member 23 of the first rotating mechanism 20 is provided with a third rotating hole 2211. The third rotating shaft 2210 is inserted into the third rotating hole 2211, allowing it to rotate within the third rotating hole 2211, thereby causing the second rotating member 22 of the first rotating mechanism 20 to rotate relative to the connecting member 23 of the first rotating mechanism 20. Of course, in other embodiments, the third rotating shaft 2210 may also be disposed on the connecting member 23 of the first rotating mechanism 20, and the third rotating hole 2211 may be disposed on opposite sides of the second rotating member 22 of the first rotating mechanism 20.

[0140] It is worth noting that the third rotating hole 2211 mentioned in this embodiment can be a through hole or a blind hole. A through hole refers to the third rotating hole 2211 penetrating both opposite surfaces of the structural member, while a blind hole refers to the third rotating hole 2211 penetrating only one surface of the structural member. Therefore, a blind hole can also be called a groove.

[0141] Furthermore, the connection between the third rotating shaft 2210 and the connecting member 23 of the first rotating mechanism 20 or the second rotating member 22 of the first rotating mechanism 20 can be fixed or rotatably connected. For example, in this embodiment, the third rotating shaft 2210 is disposed on the second rotating member 22 of the first rotating mechanism 20. The third rotating shaft 2210 can be fixedly disposed on the second rotating member 22 of the first rotating mechanism 20 so that the third rotating shaft 2210 and the second rotating member 22 of the first rotating mechanism 20 remain relatively stationary. The third rotating shaft 2210 is inserted into the third rotating hole 2211 and rotates relative to the third rotating hole 2211, thereby causing the connecting member 23 of the first rotating mechanism 20 to rotate relative to the second rotating member 22 of the first rotating mechanism 20. Alternatively, the third rotating shaft 2210 can also be rotatably connected to the second rotating member 22 of the first rotating mechanism 20, so that the third rotating shaft 2210 and the second rotating member 22 of the first rotating mechanism 20 maintain relative rotation. In this way, the third rotating shaft 2210 can still rotate within the third rotating hole 2211, thereby causing the connecting member 23 of the first rotating mechanism 20 to rotate relative to the second rotating member 22 of the first rotating mechanism 20. For example, the second rotating member 22 of the first rotating mechanism 20 has a third receiving hole 2212 that extends through its opposite sides, the third rotating shaft 2210 passes through the third receiving hole 2212, and both opposite ends of the third rotating shaft 2210 protrude from the opposite sides of the second rotating member 22 of the first rotating mechanism 20.

[0142] Optionally, when the third rotating shaft 2210 is fixed to the second rotating component 22 of the first rotating mechanism 20, the third rotating shaft 2210 and the second rotating component 22 of the first rotating mechanism 20 can be an integral structure or a separate structure. When the third rotating shaft 2210 and the second rotating component 22 of the first rotating mechanism 20 are an integral structure, they are manufactured in one process; however, for ease of understanding, the third rotating shaft 2210 and the second rotating component 22 of the first rotating mechanism 20 are given different names. When the third rotating shaft 2210 and the second rotating component 22 of the first rotating mechanism 20 are separate structures, they are manufactured separately and then joined together by various methods, such as insertion. This embodiment is only illustrated using the example of the third rotating shaft 2210 and the second rotating component 22 of the first rotating mechanism 20 being separate structures.

[0143] Please refer to this again. Figures 19-20 In this embodiment, the first rotation axis C11 between the first rotating member 21 of the first rotating mechanism 20 and the bracket 10 is parallel to or coincides with the second rotation axis C22 between the second rotating member 22 of the first rotating mechanism 20 and the bracket 10.

[0144] Firstly, the parallel rotation axes of the two rotating axes allow the connecting member 23 of the first rotating mechanism 20 to rotate smoothly. Furthermore, when the connecting member 23 rotates, it drives both the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 to rotate relative to the bracket 10, preventing jamming or other problems during rotation. Secondly, when the folding device 1 is in a static state—for example, in an unfolded or folded state, or any state between the unfolded and folded states—the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 remain stationary. This prevents the bracket 10 from rotating relative to the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20, improving the stability of the folding device 1 and enabling it to perform functions such as hovering and self-locking in a certain state.

[0145] Optionally, in some embodiments, in the horizontal direction, the first rotation axis C11 is more inward than the second rotation axis C22, that is, the first rotation axis C11 is closer to the centerline of the bracket 10 than the second rotation axis C22. Alternatively, the first rotation axis C11 is more outward than the second rotation axis C22, that is, the first rotation axis C11 is farther from the centerline of the bracket 10 than the second rotation axis C22. In other embodiments, in the vertical direction, the first rotation axis C11 is closer to the bottom surface 102 of the bracket 10 than the second rotation axis C22, that is, the first rotation axis C11 is lower than the second rotation axis C22. Alternatively, the first rotation axis C11 is farther from the bottom surface 102 of the bracket 10 than the second rotation axis C22, that is, the first rotation axis C11 is higher than the second rotation axis C22. This embodiment is only illustrated with the first rotation axis C11 being more to the upper left than the second rotation axis C22. Of course, in other embodiments, the first rotation axis C11 and the second rotation axis C22 can also be set to coincide, without affecting the movement process of the folding device 1.

[0146] Furthermore, regarding the positions of the first rotation axis C11 and the second rotation axis C22 relative to the bracket 10, the two rotation axes can be located inside the bracket 10, or they can be located outside the bracket 10, or one rotation axis can be located inside the bracket 10 and the other outside the bracket 10. The specific location within the bracket 10 depends on the cooperative structure between the rotating component, the first driven component 71, and the bracket 10.

[0147] Please refer to this as well. Figures 24-27 , Figure 24 This is a schematic diagram showing the cooperation of the first rotating component, the second rotating component, and the bracket of the first rotating mechanism in one embodiment of this application. Figure 25 for Figure 24 The diagram shows the cooperation of the first rotating component, the second rotating component, and part of the support of the first rotating mechanism. Figure 26 for Figure 24 An exploded view of the first rotating component, the second rotating component, and the support of the first rotating mechanism shown. Figure 27 for Figure 26 The diagram shows an exploded view of the bracket from another perspective. In this embodiment, the first rotating member 21 of the first rotating mechanism 20 is connected to the bracket 10 at one end near the bracket 10 via a first arc track 2100 and a first arc groove 2101. The first arc track 2100 is located on one of the first rotating member 21 of the first rotating mechanism 20 and the bracket 10, and the first arc groove 2101 is located on the other. The second rotating member 22 of the first rotating mechanism 20 is connected to the bracket 10 at one end near the bracket 10 via a second arc track 2200 and a second arc groove 2201. The second arc track 2200 is located on one of the second rotating member 22 of the first rotating mechanism 20 and the bracket 10, and the second arc groove 2201 is located on the other.

[0148] In this embodiment, both rotating components and the support 10 can be rotatably connected through the cooperation of an arc-shaped rail and an arc-shaped groove. Specifically, the first rotating component 21 of the first rotating mechanism 20 is connected to the support 10 through the cooperation of the first arc-shaped groove 2101 and the first arc-shaped rail 2100. For example, when the first arc-shaped rail 2100 is provided on the first rotating component 21 of the first rotating mechanism 20, the first arc-shaped groove 2101 is provided on the support 10; when the first arc-shaped groove 2101 is provided on the first rotating component 21 of the first rotating mechanism 20, the first arc-shaped rail 2100 is provided on the support 10. This embodiment is only illustrated with the example of the first arc-shaped rail 2100 being provided on the first rotating component 21 of the first rotating mechanism 20 and the first arc-shaped groove 2101 being provided on the support 10. Specifically, the bracket 10 is provided with an arc-shaped groove, and the first rotating member 21 of the first rotating mechanism 20 is provided with an arc-shaped block corresponding to the shape of the arc-shaped groove at one end near the bracket 10. The first arc-shaped rail 2100 can be provided in the first arc-shaped groove 2101 and abut against the inner wall of the first arc-shaped groove 2101. The axis of the first arc-shaped groove 2101 is collinear with the axis of the first arc-shaped rail 2100. The axis of the first arc-shaped groove 2101 is collinear with the first rotation axis C11 between the first rotating member 21 of the first rotating mechanism 20 and the bracket 10, so that the first rotating member 21 of the first rotating mechanism 20 can rotate relative to the bracket 10.

[0149] The dimensions and curvature of the first arc groove 2101 and the first arc rail 2100 can be designed according to the required position of the first rotation axis C11. In addition, the design of the arc groove and the arc cabinet allows the position of the first rotation axis C11 to be either inside or outside the bracket 10. For example, the position of the first rotation axis C11 can be better designed by changing the radius and central angle of the arc groove.

[0150] Of course, in other embodiments, the first arc groove 2101 can also be provided on the first rotating member 21 of the first rotating mechanism 20, and the first arc rail 2100 can also be provided on the bracket 10.

[0151] Similarly, the second rotating component 22 of the first rotating mechanism 20 is connected to the support 10 via a second arc groove 2201 and a second arc rail 2200. When the second arc rail 2200 is located on the second rotating component 22 of the first rotating mechanism 20, the second arc groove 2201 is located on the support 10; when the second arc groove 2201 is located on the second rotating component 22 of the first rotating mechanism 20, the second arc rail 2200 is located on the support 10. This embodiment is only illustrated with the second arc rail 2200 located on the second rotating component 22 of the first rotating mechanism 20 and the second arc groove 2201 located on the support 10. Specifically, the bracket 10 is provided with an arc-shaped groove, and the second rotating member 22 of the first rotating mechanism 20 is provided with an arc-shaped block corresponding to the shape of the arc-shaped groove at one end near the bracket 10. The second arc rail 2200 can be provided in the second arc groove 2201 and abut against the inner wall of the second arc groove 2201. The axis of the second arc groove 2201 is collinear with the axis of the second arc rail 2200. The axis of the second arc groove 2201 is collinear with the second rotation axis C22 between the second rotating member 22 of the first rotating mechanism 20 and the bracket 10, so that the second rotating member 22 of the first rotating mechanism 20 can rotate relative to the bracket 10.

[0152] The dimensions and curvature of the second arc groove 2201 and the second arc rail 2200 can be designed according to the required position of the second rotation axis C22. In addition, the design of the arc groove and the arc cabinet allows the position of the second rotation axis C22 to be either inside or outside the bracket 10. For example, the position of the second rotation axis C22 can be better designed by changing the radius and central angle of the arc groove.

[0153] Of course, in other embodiments, the second arc groove 2201 can also be provided on the second rotating member 22 of the first rotating mechanism 20, and the second arc rail 2200 can also be provided on the bracket 10.

[0154] Please refer to this as well. Figures 28-29 , Figure 28This is a schematic diagram showing the connection between the first support member and the first rotating mechanism in one embodiment of this application. Figure 29 for Figure 28 The diagram shows an exploded view of the connection between the first support member and the first rotating mechanism. In this embodiment, the first support member 31 includes a support portion 313 and a guide portion 315. The support portion 313 has a support surface 310 for supporting the member to be supported. The guide portion 315 is fixed on a surface opposite to the support surface 310. The guide portion 315 and the connection member 23 of the first rotating mechanism 20 are connected by a third arc track 3150 and a third arc groove 3151. The third arc track 3150 is provided in one of the connection members 23 of the guide portion 315 and the first rotating mechanism 20, and the third arc groove 3151 is provided in the other of the connection members 23 of the guide portion 315 and the first rotating mechanism 20.

[0155] The first support member 31 may include a support portion 313 and a guide portion 315. The support portion 313 will not be described in detail in this embodiment. The guide portion 315 is disposed on one side of the support portion 313 and is used to achieve a rotatable connection with the connecting member 23 of the first rotating mechanism 20. Specifically, the guide portion 315 is disposed on the non-support surface 311, that is, the guide portion 315 is closer to the connecting member 23 of the first rotating mechanism 20 than the support portion 313.

[0156] Furthermore, the support portion 313 and the guide portion 315 can be either an integral structure or a separate structure. When the support portion 313 and the guide portion 315 are an integral structure, they are manufactured in a single process; however, for ease of understanding, the support portion 313 and the guide portion 315 are given different names. When the support portion 313 and the guide portion 315 are separate structures, they are manufactured separately and then connected together using various methods. This embodiment is only illustrated illustratively using the example of the support portion 313 and the guide portion 315 being an integral structure.

[0157] Optionally, the support part 313, guide part 315, and rolling part 314 can all be integral structures, meaning that the support part 313, guide part 315, and rolling part 314 are all manufactured in a single process. Alternatively, they can all be separate structures, meaning that the support part 313, guide part 315, and rolling part 314 are manufactured separately and then combined together using various methods. Or, some of the three can be integral structures, while the remaining parts can be separate structures, meaning that some components of the support part 313, guide part 315, and rolling part 314 are manufactured in a single process, while the remaining components are manufactured separately and then combined together using various methods.

[0158] Therefore, the aforementioned rotatable connection between the first support member 31 and the connecting member 23 of the first rotating mechanism 20 is equivalent to the rotatable connection between the guide portion 315 and the connecting member 23 of the first rotating mechanism 20. Specifically, the guide portion 315 and the connecting member 23 of the first rotating mechanism 20 are connected by a third arc groove 3151 and a third arc rail 3150. The third arc groove 3151 is provided on one of the guide portion 315 and the connecting member 23 of the first rotating mechanism 20, and the third arc rail 3150 is provided on the other. For example, when the third arc groove 3151 is provided on the guide portion 315, the third arc rail 3150 is provided on the connecting member 23 of the first rotating mechanism 20; when the third arc groove 3151 is provided on the connecting member 23 of the first rotating mechanism 20, the third arc rail 3150 is provided on the guide portion 315. This embodiment is only illustrated with the third arc groove 3151 provided on the guide portion 315 and the third arc rail 3150 provided on the connector 23 of the first rotating mechanism 20. Specifically, the guide portion 315 has an arc-shaped groove on the side surface near the connector 23 of the first rotating mechanism 20. The connector 23 of the first rotating mechanism 20 is correspondingly provided with an arc-shaped block inserted into the third arc groove 3151. The third arc rail 3150 can be provided in the third arc groove 3151 and abut against the inner wall of the third arc groove 3151. The axis of the third arc groove 3151 is collinear with the axis of the third arc rail 3150. The axis of the third arc groove 3151 is collinear with the axis of rotation between the support portion 313 and the connector 23 of the first rotating mechanism 20, so that the support portion 313 can rotate relative to the connector 23 of the first rotating mechanism 20. The dimensions and curvature of the third arc groove 3151 and the third arc rail 3150 can be designed according to the required position of the fourth rotation axis C4. Furthermore, the design of the arc groove and arc rail allows the fourth rotation axis C4 to be positioned either inside or outside the guide portion 315. For example, the position of the fourth rotation axis C4 can be better designed by changing the radius and central angle of the arc groove.

[0159] Of course, in other embodiments, the third arc groove 3151 may also be provided on the connecting member 23 of the first rotating mechanism 20, and the third arc rail 3150 may also be provided on the guide portion 315.

[0160] Optionally, the non-supporting surface 311 of the support portion 313 is provided with a guide portion 315 at the end away from the bracket 10, and the guide portion 315 is an arc-shaped block. Further optionally, the guide portion 315 has a third arc groove 3151 on the side facing the connector 23 of the first rotating mechanism 20, and the opposite ends of the third arc groove 3151 penetrate the side surface of the guide portion 315 near the support portion 313 and the side surface of the guide portion 315 away from the bracket 10.

[0161] Optionally, in some embodiments, the non-supporting surface 311 of the support portion 313 is provided with guide portions 315 at opposite ends of the connector 23 corresponding to the first rotating mechanism 20. The surfaces of the two guide portions 315 facing each other are provided with third arc grooves 3151, and the axis lines of the two third arc grooves 3151 are collinear. The opposite sides of the connector 23 of the first rotating mechanism 20 are provided with third arc rails 3150, and the two third arc rails 3150 can be respectively inserted into the third arc grooves 3151.

[0162] Please refer to this again. Figures 25-26 In this embodiment, the bracket 10 includes a first sub-bracket 110 and a second sub-bracket 120. The first rotating component 21 and the second rotating component 22 of the first rotating mechanism 20 are sandwiched between the first sub-bracket 110 and the second sub-bracket 120 and are rotatably connected through the first sub-bracket 110 and the second sub-bracket 120.

[0163] The bracket 10 in this embodiment is composed of a split first sub-bracket 110 and a second sub-bracket 120, meaning that the first sub-bracket 110 and the second sub-bracket 120 are manufactured separately and then assembled together by various methods such as bonding, snap-fitting, or screw connection. The first rotating component 21 and the second rotating component 22 of the first rotating mechanism 20 are sandwiched between the first sub-bracket 110 and the second sub-bracket 120, and the first sub-bracket 110 and the second sub-bracket 120 cooperate with each other to achieve a rotatable connection with the first rotating component 21 and the second rotating component 22 of the first rotating mechanism 20. For example, as mentioned above, this application uses one end of the first rotating component 21 and the second rotating component 22 of the first rotating mechanism 20 as the rotation axis for schematic description. Therefore, the bracket 10 is provided with a corresponding first arc groove 2101 and a second arc groove 2201. Therefore, two accommodating spaces 111 can be formed on the first sub-support 110, and a protrusion 121 can be provided on the opposite sidewall 52 of each accommodating space 111. When the first sub-support 110 and the second sub-support 120 are assembled together, the first sub-support 110, the second sub-support 120, and the protrusion 121 of each accommodating space 111 together form a corresponding arc groove. In addition, through holes 122 communicating with the accommodating spaces 111 can be formed on the opposite sides of the protrusion 121 on the second sub-support 120 to avoid interference between the first rotating part 21 and the second rotating part 22 of the first rotating mechanism 20.

[0164] In other embodiments, the support 10 can also be designed as an integral structure, that is, the first sub-support 110 and the second sub-support 120 are inseparable structural forms.

[0165] The relevant structures and positional relationships of the second rotating mechanism 20', the second support member 31', and the second driven member 71' can be understood in the same way as those of the first rotating mechanism 20, the first support member 31, and the first driven member 71. For example: In this embodiment, the second support member 31' includes a support portion 313 and a rolling portion 314 disposed on the side of the support portion 313 near the connector 23. The rolling portion 314 is slidably and rotatably connected to the end of the second follower member 71' away from the bracket 10. The rolling portion 314 and the second follower member 71' are connected by a first rolling shaft 3141 and a first rolling groove 3140. The first rolling shaft 3141 is disposed on one of the rolling portion 314 and the second follower member 71', and the first rolling groove 3140 is disposed on the other of the rolling portion 314 and the second follower member 71'.

[0166] In this embodiment, the support portion 313 has a support surface 310 for supporting the component to be supported, and the first rolling groove 3140 has a first limiting end 3140a and a second limiting end 3140b with opposite sides. The first limiting end 3140a is farther away from the bracket 10 than the second limiting end 3140b, and the first limiting end 3140a is farther away from the support surface 310 than the second limiting end.

[0167] In this embodiment, the first rolling groove 3140 also has a first connecting portion 3140c that connects the first limiting end 3140a and the second limiting end 3140b. From the first limiting end 3140a to the first connecting portion 3140c and then to the second limiting end 3140b, the distance between the first rolling groove 3140 and the support surface 310 gradually decreases.

[0168] In this embodiment, the third rotation axis C3 between the second follower 71' and the connecting member 23 of the second rotation mechanism 20' is farther away from the bracket 10 than the fourth rotation axis C4 between the second follower 71' and the rolling part 314.

[0169] In this embodiment, the end of the second driven member 71' away from the bracket 10 is connected to the connector 23 of the second rotating mechanism 20' through a first rotating shaft 7110 and a first rotating hole 7111.

[0170] In this embodiment, the end of the second follower 71' near the bracket 10 is connected to the bracket 10 through a second rolling shaft 7101 and a second rolling groove 7100. The second rolling shaft 7101 is provided in one of the second follower 71' and the bracket 10, and the second rolling groove 7100 is provided in the other of the second follower 71' and the bracket 10.

When the first support member 31 and the second support member 31' are in a fully extended state, the third limiting end 7100a is farther away from the second support member 31' than the fourth limiting end 7100b, and the third limiting end 7100a is farther away from the support surface 310 than the fourth limiting end.

[0172] In this embodiment, the second rolling groove 7100 also has a second connecting portion 7100c that connects the third limiting end 7100a and the fourth limiting end 7100b, and the second connecting portion 7100c protrudes in a direction away from the support surface 310.

[0173] In this embodiment, the first rotation axis C1 is farther away from the bracket 10 than the second rotation axis C2.

[0174] In this embodiment, the second support member 31' has a support surface 310, and the first rotation axis C1 is closer to the support surface 310 than the second rotation axis C2.

[0175] In this embodiment, the end of the first rotating member 21 of the second rotating mechanism 20' away from the support 10 is connected to the connecting member 23 of the second rotating mechanism 20' via a second rotating shaft 2110 and a second rotating hole 2111. The second rotating shaft 2110 is located in one of the first rotating member 21 and the connecting member 23 of the second rotating mechanism 20', and the second rotating hole 2111 is located in the other of the two rotating members 21 and the connecting member 23 of the second rotating mechanism 20'. The end of the second rotating member 22 of the second rotating mechanism 20' away from the support 10 is connected to the connecting member 23 of the second rotating mechanism 20' via a third rotating shaft 2210 and a third rotating hole 2211. The third rotating shaft 2210 is located in one of the second rotating member 22 and the connecting member 23 of the second rotating mechanism 20', and the third rotating hole 2211 is located in the other of the two rotating members 22 and the connecting member 23 of the second rotating mechanism 20'.

[0176] In this embodiment, the first rotation axis C11 between the first rotating member 21 of the second rotating mechanism 20' and the bracket 10 is parallel to or coincides with the second rotation axis C22 between the second rotating member 22 of the second rotating mechanism 20' and the bracket 10.

[0177] In this embodiment, the first rotating member 21 of the second rotating mechanism 20' is connected to the support 10 at one end near the support 10 via a first arc track 2100 and a first arc groove 2101. The first arc track 2100 is located on one of the first rotating member 21 of the second rotating mechanism 20' and the support 10, and the first arc groove 2101 is located on the other. The second rotating member 22 of the second rotating mechanism 20' is connected to the support 10 at one end near the support 10 via a second arc track 2200 and a second arc groove 2201. The second arc track 2200 is located on one of the second rotating member 22 of the second rotating mechanism 20' and the support 10, and the second arc groove 2201 is located on the other.

[0178] In this embodiment, the second support member 31' includes a support portion 313 and a guide portion 315. The support portion 313 has a support surface 310 for supporting the member to be supported. The guide portion 315 is fixed on a side surface opposite to the support surface 310. The guide portion 315 and the connecting member 23 of the second rotating mechanism 20' are connected by a third arc rail 3150 and a third arc groove 3151. The third arc rail 3150 is provided in one of the connecting members 23 of the guide portion 315 and the second rotating mechanism 20', and the third arc groove 3151 is provided in the other connecting member 23 of the guide portion 315 and the second rotating mechanism 20'.

[0179] In this embodiment, the bracket 10 includes a first sub-bracket 110 and a second sub-bracket 120. The first rotating component 21 and the second rotating component 22 of the second rotating mechanism 20' are sandwiched between the first sub-bracket 110 and the second sub-bracket 120 and are rotatably connected through the first sub-bracket 110 and the second sub-bracket 120.

[0180] Furthermore, for a detailed description of the above structures, please refer to the relevant descriptions and accompanying drawings of the first rotating mechanism 20, the first support member 31, and the first driven member 71; these will not be repeated here. Moreover, the structures of the second rotating mechanism 20', the second support member 31', and the second driven member 71' are merely illustrative examples in this application. Other structural features of the first rotating mechanism 20, the first support member 31, and the first driven member 71 are equally applicable to the second rotating mechanism 20', the second support member 31', and the second driven member 71', and should also fall within the scope of protection of this application.

[0181] In addition to the aforementioned structural components, the folding device 1 may also include a synchronization mechanism or a suspension mechanism. The synchronization mechanism enables the first support member 31 on the other side of the support 10 to move synchronously and in opposite directions when the connecting member 23 of the first rotating mechanism 20 on one side of the bracket 10 rotates, thereby driving the first support member 31 to move. This achieves synchronous folding and unfolding of the first support member 31 and the second support member 31'. The suspension mechanism ensures that when the connecting member 23 of the first rotating mechanism 20 rotates to a certain angle, if the external force is removed, the connecting member 23 of the first rotating mechanism 20 remains fixed and stationary, and will not automatically fall back. The specific structures of the synchronization mechanism and the suspension mechanism will not be described in detail here. Furthermore, in addition to providing a folding device 1, this application also provides a housing assembly 2 assembled using the folding device 1.

[0182] Please refer to this as well.

Figure 31 for Figure 30 The exploded view of a portion of the housing assembly is shown. Figure 32 for Figure 30 The front view of the housing assembly shown. Figures 33-34 They are respectively Figure 30 The diagram shows cross-sectional views of different parts of the housing assembly. Figure 35 This is a three-dimensional structural diagram of the housing assembly in a folded state according to one embodiment of this application. Figure 36 for Figure 35 The front view of the housing assembly shown. Figures 37-38 They are respectively Figure 30 The diagram shows cross-sectional views of different parts of the housing assembly.

[0183] This embodiment provides a housing assembly 2, which includes a first housing 40, a second housing 40', and a folding device 1 as described in the above embodiments of this application. At least a portion of the first housing 40 and the second housing 40' are disposed on opposite sides of the folding device 1. The first housing 40 is connected to a connector 23 of the first rotation mechanism 20 of the folding device 1, and the second housing 40' is connected to a connector 23 of the second rotation mechanism 20' of the folding device 1. When the connectors 23 of the first rotation mechanism 20 and the second rotation mechanism 20' rotate, the first housing 40 and the second housing 40' switch between an unfolded state and a folded state.

[0184] The housing assembly 2 is a modular component, meaning it comprises at least two parts. In this embodiment, the housing assembly 2 mainly includes a first housing 40, a second housing 40', and the folding device 1 described in the above embodiment. The first housing 40 and the second housing 40' of the folding device 1 are mainly used for mounting and supporting structural components. For example, components to be supported can be mounted on the first housing 40 and the second housing 40', and structural components such as circuit boards, batteries, and cameras can be installed inside the first housing 40 and the second housing 40'. Therefore, the first housing 40 and the second housing 40' mainly serve the functions of mounting and protection. In some embodiments, the surfaces of the first housing 40 and the second housing 40' can also serve as appearance surfaces. Therefore, the surfaces of the first housing 40 and the second housing 40' can be designed accordingly to give them a unique external appearance. This embodiment does not limit the shape, material, structure, or other parameters of the first housing 40 and the second housing 40', as long as the functions of mounting and protection are achieved. For example, the materials of the first housing 40 and the second housing 40' can be entirely metal, entirely plastic, or partially metal and partially plastic.

[0185] The connector 23 of the folding device 1 can be fixed to the housing 40. That is, the first housing 40 is connected to the connector 23 of the first rotating mechanism 20 of the folding device 1, and the second housing 40'40' is connected to the connector 23 of the second rotating mechanism 20'20' of the folding device 1. In other words, the first housing 40 and the connector 23 of the first rotating mechanism 20 can be an integral structure or a separate structure. When the first housing 40 and the connector 23 of the first rotating mechanism 20 are an integral structure, they are manufactured in one process. However, for ease of understanding, the connector 23 of the first housing 40 and the first rotating mechanism 20 are given different names. When the first housing 40 and the connector 23 of the first rotating mechanism 20 are separate structures, they are manufactured separately and then assembled together by various methods such as screw connection, bonding, snap-fit, etc. This embodiment is only illustrated with the first housing 40 and the connecting member 23 of the first rotating mechanism 20 as a separate structure.

[0186] At least portions of the first housing 40 and the second housing 40' are disposed on opposite sides of the folding device 1. In some embodiments, all of the first housing 40 and the second housing 40' may be disposed on opposite sides of the folding device 1, for example, each first housing 40 may be disposed on a first side 103 of the support 10. In other embodiments, portions of the first housing 40 and the second housing 40' are disposed on opposite sides of the folding device 1, while the remaining portions are disposed on other sides of the folding device 1. For example, a portion of each first housing 40 may be disposed on a first side 103 of the support 10, with the remainder disposed on the bottom surface 102 of the support 10.

[0187] When the first housing 40 is fixed to the connector 23 of the first rotating mechanism 20, when the first housing 40 is subjected to an external force applied by the user or an external force given by other mechanisms, the first housing 40 rotates, thereby driving the connector 23 of the first rotating mechanism 20 to rotate. The rotation of the connector 23 of the first rotating mechanism 20 can drive the first rotating member 21, the second rotating member 22, and the first support member 31 to rotate, and at the same time drive the first driven member 71 to slide and rotate relative to the bracket 10, so that the first driven member 71 also rotates relative to the connector 23 of the first rotating mechanism 20, thereby driving the first support member 31 to slide and rotate relative to the first driven member 71, and further driving the first support member 31 to rotate relative to the connector 23 of the first rotating mechanism 20, until the first support member 31 and the second support member 31' and the bracket 10 are bent into a teardrop shape or unfolded into a horizontal shape.

[0188] The housing assembly 2 provided in this embodiment, by employing the folding device 1 provided in the above-described embodiments of this application, ensures that the dimensions of the housing assembly 2 in the length direction do not change, which is beneficial for miniaturization. Furthermore, it prevents the first housing 40 from rotating relative to the first rotating member 21 and the second rotating member 22, thus improving the stability of the housing assembly 2.

[0189] Please refer to this as well. Figures 39-42 , Figure 39 This is a schematic diagram illustrating the cooperation between the decorative element and the folding device in one embodiment of this application. Figure 40 for Figure 39 An exploded view of the decorative element and folding device shown. Figure 41 This is an exploded view of the first rotating member, the second rotating member, the driven member, and the decorative member in one embodiment of this application. Figure 42This is an exploded view of the first rotating member, the second rotating member, the driven member, and the decorative member in another embodiment of this application. In this embodiment, the housing assembly 2 further includes a decorative member 50, which includes a bottom wall 51 and a side wall 52 bent and connected to the periphery of the bottom wall 51. The bracket 10 of the folding device 1 is fixed to the bottom wall 51. The first rotating member 21, the second rotating member 22, the first driven member 71, and the second driven member 71' of the first rotating mechanism 20 and the second rotating mechanism 20' of the folding device 1 all include a clearance portion 53, which is used to avoid the side wall 52. Alternatively, the side wall 52 is provided with a clearance space 54, and the first rotating member 21, the second rotating member 22, the first driven member 71, and the second driven member 71' of the first rotating mechanism 20 and the second rotating mechanism 20' can be disposed within the clearance space 54.

[0190] In addition to the first housing 40 and the folding device 1, the housing assembly 2 may also include a decorative element 50. The mounting element is mainly used to mount the folding device 1, providing a mounting base for the folding device 1. The decorative element 50 also protects the folding device 1, preventing it from being damaged by contact with the outside environment. Simultaneously, the decorative element 50, together with the first housing 40 and the second housing 40', can form the outer surface of the housing assembly 2. Therefore, the surface of the decorative element 50 can be designed in the same way, thereby improving the appearance performance of the housing assembly 2. This embodiment does not limit the material, shape, structure, or other parameters of the decorative element 50, as long as the decorative element 50 can achieve the functions of mounting, protection, and appearance.

[0191] The decorative element 50 may include a bottom wall 51 and a side wall 52 that is bent and connected to the periphery of the bottom wall 51. In this embodiment, the bracket 10 can be fixed to the bottom wall 51. In some embodiments, the bracket 10 can be screwed to the bottom wall 51 by means of screws or the like. In other embodiments, it can also be fixed by means of adhesive, snap-fit ​​connection or the like.

[0192] Optionally, the housing assembly 2 may include two or more folding devices 1, with the plurality of folding devices 1 spaced apart on the bottom wall 51 along the length direction of the bottom wall 51.

[0193] Due to the presence of the sidewall 52 of the decorative element 50, the first rotating member 21, the second rotating member 22, the first driven member 71, and the second driven member 71' of the first rotating mechanism 20 and the second rotating mechanism 20' in the housing assembly 2 may interfere with the sidewall 52 when they move to the flattened state, thereby hindering the rotation of the first rotating member 21, the second rotating member 22, the first driven member 71, and the second driven member 71' of the first rotating mechanism 20 and the second rotating mechanism 20'. Therefore, this embodiment provides two solutions. In one embodiment, a clearance portion 53 can be provided on the first rotating member 21, the second rotating member 22, the first driven member 71, and the second driven member 71' of the first rotating mechanism 20 and the second rotating mechanism 20' to avoid the sidewall 52. Specifically, a clearance portion 53 may be provided on the side of the first rotating member 21, the second rotating member 22, the first driven member 71, and the second driven member 71' of the first rotating mechanism 20 and the second rotating mechanism 20' that is close to the bottom wall 51, and the clearance portion 53 may protrude in a direction away from the side wall 52, thereby preventing the side wall 52 from interfering with the first rotating member 21 and the second rotating member 22.

[0194] In the second embodiment, two clearance spaces 54 can be provided on the side wall 52. When the first support member 31 and the second support member 31' are fully extended, the first rotating member 21, the second rotating member 22, the first driven member 71, and the second driven member 71' of the first and second rotating mechanisms 20 and 20' can each be located within a clearance space 54, thereby preventing interference between the side wall 52 and the first rotating member 21, the second rotating member 22, the first driven member 71, and the second driven member 71' of the first and second rotating mechanisms 20 and 20'. Specifically, the clearance space 54 can simultaneously penetrate the side surface of the side wall 52 facing away from the bottom wall 51, the side surface of the side wall 52 close to the bracket 10, and the side surface of the side wall 52 away from the bracket 10. The bottom wall 51 may not have clearance spaces 54, preventing the user from seeing the interior of the housing assembly 2 through the bottom wall 51, thus more effectively protecting the housing assembly 2.

[0195] In addition, whether the avoidance part 53 is provided or the avoidance space 54 is provided on the side wall 52, in addition to the avoidance function, the above-mentioned avoidance design can also be used to make the first rotating member 21, the second rotating member 22, the first driven member 71, the second driven member 71' and the side wall 52 contact when the first supporting member 31 and the second supporting member 31' are in a fully extended state. The side wall 52 is used to limit the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 and the second rotating mechanism 20', and prevent the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 and the second rotating mechanism 20' from folding back and damaging the housing assembly 2.

[0196] Please refer to this again. Figures 30-34 In this embodiment, both the first housing 40 and the second housing 40' include a body 41 and a protrusion 42 provided on the side of the body 41 near the folding device 1. The connector 23 of the first rotating mechanism 20 is fixed on the protrusion 42 of the first housing 40, and the connector 23 of the second rotating mechanism 20' is fixed on the protrusion 42 of the second housing 40'. When the housing assembly 2 is in the unfolded state, the protrusion 42 of the first housing 40 and the protrusion 42 of the second housing 40' are located on the side of the decorative piece 50 away from the folding device 1.

[0197] This embodiment provides a specific structure in which a first housing 40 and a second housing 40' are partially disposed on opposite sides of a folding device 1. The first housing 40 includes a body 41 and a protrusion 42. The body 41 supports the component to be supported and has space within it for accommodating and installing various structural components, such as batteries, circuit boards, camera modules, etc. Since this embodiment includes a first housing 40 and a second housing 40', different structural components can be provided within the body 41 of each first housing 40. The protrusion 42 is mainly used to install the connecting member 23 of the first rotating mechanism 20 in the folding device 1, and also serves to protect the folding device 1. In other embodiments, smaller structural components, such as small plates, can also be provided within the protrusion 42.

[0198] The body 41 and the protrusion 42 can be either an integral structure or a separate structure. When the body 41 and the protrusion 42 are an integral structure, they are manufactured in a single process; however, for ease of understanding, the body 41 and the protrusion 42 are given different names. When the body 41 and the protrusion 42 are separate structures, they are manufactured separately and then connected together by various methods, such as insertion. This embodiment is only illustrated illustratively using the case where the body 41 and the protrusion 42 are an integral structure.

[0199] The main body 41 has a front side 410, a back side 411, and a side side 412 that is bent and connected between the front side 410 and the back side 411 and is close to the folding device 1. The front side 410 is used to support the component to be supported, the back side 411 serves as the exterior surface of the housing assembly 2, and the side side 412 is used to provide the protrusion 42. Specifically, the protrusion 42 is provided on the side side 412 and close to the back side 411, so that the protrusion 42 and the main body 41 can form a stepped structure, that is, form an upward mounting space 413. The connecting member 23 of the first rotating mechanism 20 and part of the first support member 31 can be provided in the mounting space 413, and the connecting member 23 of the first rotating mechanism 20 is fixed to the surface of the protrusion 42 close to the front side 410. Optionally, the surface of the protrusion 42 opposite to the front side 410 is flush with the back side 411 of the main body 41 to improve the flatness of the surface of the first housing 40.

[0200] When the first support member 31 and the second support member 31' are fully extended, i.e., when the housing assembly 2 is in the extended state, the two protrusions 42 can be provided on the side of the decorative member 50 away from the folding device 1. This allows the entire folding device 1 to be placed within the mounting space 413 of the first housing 40 and the second housing 40', and the two protrusions 42 can be used to cover the decorative member 50 and the folding device 1, making the housing assembly 2 more visually concise. Optionally, when the first support member 31 and the second support member 31' are fully extended, the two protrusions 42 can abut against each other, or there can be a certain gap between the two protrusions 42.

[0201] When the first support member 31 and the second support member 31' are fully folded together, that is, when the housing assembly 2 is in the folded state, the two protrusions 42, together with their respective connected bodies 41, are located on opposite sides of the folding device 1 and the decorative member 50, and the first housing 40, the second housing 40', and the lower surface of the decorative member 50 together constitute the outer surface of the housing assembly 2. Optionally, the side wall 52 of the decorative member 50 is arc-shaped, so that the first housing 40 avoids interference with the side wall 52 during the rotation of the first housing 40.

[0202] This application also provides an electronic device 3 assembled using the aforementioned housing assembly 2. Please refer to the following: Figures 43-51 , Figure 43 This is a three-dimensional structural diagram of the electronic device in the unfolded state according to one embodiment of this application. Figure 44 for Figure 43 The diagram shows an exploded view of the electronic device's structure. Figure 45 for Figure 43 The front view of the electronic device shown. Figures 46-47 They are respectively Figure 43 The diagram shows cross-sectional views of different parts of the electronic device. Figure 48 This is a three-dimensional structural diagram of the electronic device in a folded state according to one embodiment of this application. Figure 49 for Figure 48 The rear view of the electronic device shown. Figures 50-51 They are respectively Figure 48 The diagram shows cross-sectional views of different parts of the electronic device.

[0203] This embodiment provides an electronic device 3, which includes a flexible member 60 and a housing assembly 2 as provided in the above embodiments of this application. The flexible member 60 is supported by a first support member 31 and a second support member 31' of the folding device 1. When the electronic device 3 is folded, the first housing 40 and the second housing 40' fold together, the first support member 31 and the second support member 31' fold together, and the two ends of the flexible member 60 fold together. When the electronic device 3 is unfolded, the first housing 40 and the second housing 40' unfold together, the first support member 31 and the second support member 31' unfold together, and the two ends of the flexible member 60 unfold together.

[0204] The electronic device 3 provided in this embodiment includes, but is not limited to, mobile terminals such as mobile phones, tablets, laptops, PDAs, personal computers (PCs), personal digital assistants (PDAs), portable media players (PMPs), navigation devices, wearable devices, smart bracelets, and pedometers, as well as fixed terminals such as digital TVs and desktop computers. This embodiment does not limit the type of electronic device 3. This embodiment only uses a mobile phone as an illustrative example.

[0205] The electronic device 3 includes a flexible component 60 and a housing assembly 2. The flexible component 60 is a structural component with a certain degree of flexibility, which can be bent to a certain extent compared to a rigid component. For example, the flexible component 60 includes, but is not limited to, flexible displays, flexible touch screens, flexible touch displays, and other flexible components with corresponding functions, or flexible components that are fixedly attached to a flexible support plate, such as flexible displays and flexible touch screens attached to a flexible steel plate. The flexible component 60 is located on one side of the housing assembly 2 and can be bent or flattened along with the housing assembly 2. Specifically, the flexible component 60 has a bending area 61 and non-bending areas 62 located on opposite sides of the bending area 61. The bending area 61 is corresponding to the folding device 1, and the non-bending areas 62 are corresponding to the front surface 410 of the first housing 40 and the second housing 40'. Since the flexible element 60 in the bending area 61 is attached to the folding device 1, the shape of the folding device 1 changes when it moves, thus causing the flexible element 60 in the bending area 61 to bend as well, thereby bending or flattening with the movement of the electronic device 3. Since the non-bending area 62 is fixed to the first housing 40 and the second housing 40', the first housing 40 and the second housing 40' will only rotate relative to each other, and the shape of the first housing 40 and the second housing 40' themselves will not change. Therefore, even if the first housing 40 and the second housing 40' rotate, the flexible element 60 on the first housing 40 and the second housing 40' will not bend.

[0206] The electronic device 3 also has an unfolded state and a folded state. The unfolded state refers to the state where the first support member 31 and the second support member 31' are fully unfolded, which can also be understood as the state where the flexible member 60 is flattened, or the state where the display surface of the flexible member 60 is flat. The folded state refers to the state where the first support member 31 and the second support member 31' are fully folded, which can also be understood as the state where the flexible member 60 is bent and the two halves of the flexible member 60 are close to each other, or the state where the display surface of the flexible member 60 is bent. When the electronic device 3 is folded, the first housing 40 and the second housing 40' fold together, the first support member 31 and the second support member 31' fold together, and the two ends of the flexible member 60 fold together. When the electronic device 3 is unfolded, the first housing 40 and the second housing 40' unfold together, the first support member 31 and the second support member 31' unfold together, and the two ends of the flexible member 60 unfold together. In other words, when the electronic device 3 is folded, the two housings fold first, then the two support members fold together, and finally the two ends of the flexible member 60 fold together. When the electronic device 3 unfolds, the two housings unfold first, then drive the two supporting members to unfold relative to each other, and finally cause the two ends of the flexible member 60 to unfold relative to each other. The electronic device 3 has various active-passive relationships during folding and unfolding; this embodiment will describe in detail one specific feasible method.

[0207] When the electronic device 3 needs to be bent from its unfolded state to its folded state, the user only needs to push or pull the first housing 40 towards the center of the electronic device 3 to make the first housing 40 rotate. During the rotation of the first housing 40, the connecting member 23 and the flexible member 60 of the first rotating mechanism 20 fixed on the first housing 40 will rotate, thereby causing the first rotating member 21, the second rotating member 22, and the first support member 31 connected to the connecting member 23 of the first rotating mechanism 20 to rotate relative to the bracket 10. At the same time, the first driven member 71 will slide and rotate relative to the bracket 10, causing the second rolling shaft 7101 on the first driven member 71 to move from the third limiting end 7100a to the fourth limiting end 7100b. When the first driven member 71 slides and rotates relative to the bracket 10, it can also rotate relative to the connecting member 23 of the first rotating mechanism 20. This causes the first rolling shaft 3141 on the first driven member 71 to move from the first limiting end 3140a to the second limiting end 3140b, driving the first support member 31 to slide and rotate relative to the first driven member 71. This, in turn, drives the end of the first support member 31 near the bracket 10 to rotate relative to the connecting member 23 of the first rotating mechanism 20, causing the flexible member 60 on the first support member 31 to also bend towards the connecting member 23 of the first rotating mechanism 20. The same can be applied to the second support member 31'. Finally, when the first housing 40 rotates 90°, the flexible members 60 of the non-bending areas 62 on the first housing 40 and the second housing 40' abut against each other, so that the electronic device 3 has no gap between the first housing 40 and the second housing 40', achieving complete contact. This not only effectively protects the flexible member 60 but also reduces the thickness of the electronic device 3. The flexible element 60 of the bending area 61 on the folding device 1 forms a teardrop shape that is smaller at the top and larger at the bottom.

[0208] When the electronic device 3 wants to return from the folded state to the unfolded state, the user only needs to pull the first housing 40 outward to rotate it. During the rotation of the first housing 40, the connecting member 23 and the flexible member 60 of the first rotating mechanism 20 fixed on the first housing 40 will rotate, thereby causing the first rotating member 21, the second rotating member 22, and the first support member 31 connected to the connecting member 23 of the first rotating mechanism 20 to rotate relative to the bracket 10. At the same time, the first driven member 71 will slide and rotate in the opposite direction relative to the bracket 10, causing the second rolling shaft 7101 on the first driven member 71 to move from the fourth limiting end 7100b back to the third limiting end 7100a. When the first driven member 71 slides and rotates relative to the bracket 10, it can also rotate in the opposite direction relative to the connecting member 23 of the first rotating mechanism 20. This causes the first rolling shaft 3141 on the first driven member 71 to move from the second limiting end 3140b to the first limiting end 3140a, driving the first support member 31 to slide and rotate relative to the first driven member 71. This, in turn, drives the end of the first support member 31 near the bracket 10 to rotate relative to the connecting member 23 of the first rotating mechanism 20 in a direction away from the connecting member 23, causing the first support member 31 to return to its flattened position. This, in turn, causes the flexible member 60 on the first support member 31 to bend in the opposite direction away from the connecting member 23 of the first rotating mechanism 20, giving the flexible member 60 a tendency to return to its flattened state. The same understanding applies to the second support member 31'. Finally, when the first housing 40 rotates 90° in the opposite direction, the first support member 31 and the second support member 31' return to their fully unfolded state, and the flexible member 60 also returns to its flattened shape.

[0209] In summary, the electronic device 3 provided in this embodiment, by employing the housing assembly 2 provided in the above-described embodiments of this application, ensures that the dimensions of the electronic device 3 in the length direction remain unchanged, which is beneficial for miniaturization. Furthermore, it prevents the first housing 40 from rotating relative to the first rotating member 21 and the second rotating member 22, thereby improving the stability of the electronic device 3.

[0210] The electronic device 3 can also be understood from another perspective. For example, this application also provides a foldable electronic device, including a flexible component and a folding device. The folding device includes a support 10, a first rotating mechanism 20 and a second rotating mechanism 20' arranged side by side on opposite sides of the support 10. The first rotating mechanism 20 and the second rotating mechanism 20' each include a first rotating component 21, a second rotating component 22, and a connecting component 23. One end of the first rotating component 21 and the second rotating component 22 are rotatably connected to the support 10, and the other end of the first rotating component 21 and the second rotating component 22 are rotatably connected to the connecting component 23. The first rotation axis C1 between the first rotating component 21 and the connecting component 23 is parallel and does not coincide with the second rotation axis C2 between the second rotating component 22 and the connecting component 23. The support mechanism 30 supports the flexible member 60. The support mechanism 30 includes a first support member 31 and a second support member 31' located on opposite sides of the bracket 10. The first support member 31 is rotatably connected to the connector 23 of the first rotating mechanism 20, and the second support member 31' is rotatably connected to the connector 23 of the second rotating mechanism 20'. The driven mechanism 70 includes a first driven member 71 and a second driven member 71' located on opposite sides of the bracket 10. One end of the first driven member 71 is slidably and rotatably connected to the bracket 10, and the other end is rotatably connected to the connector 23 of the first rotating mechanism 20, and also slidably and rotatably connected to the first support member 31. One end of the second driven member 71' is slidably and rotatably connected to the bracket 10, and the other end is rotatably connected to the connector 23 of the second rotating mechanism 20', and also slidably and rotatably connected to the second support member 31'. When the folding device 1 is folded, the first driven member 71, the second driven member 71', and the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 and the second rotating mechanism 20' rotate, while the first driven member 71 and the second driven member 71' also slide, the first support member 31 and the second support member 31' fold together, and the two ends of the flexible member 60 fold together. When the folding device 1 is unfolded, the first driven member 71, the second driven member 71', and the first rotating member 21 and the second rotating member 22 of the first rotating mechanism 20 and the second rotating mechanism 20' rotate, while the first driven member 71 and the second driven member 71' also slide, the first support member 31 and the second support member 31' unfold together, and the two ends of the flexible member 60 fold together.

[0211] In this embodiment, the first support member 31 includes a support portion 313 and a rolling portion 314 disposed on the side of the support portion 313 near the connector 23. The rolling portion 314 is slidably and rotatably connected to the end of the first driven member 71 away from the bracket 10. The rolling portion 314 and the first driven member 71 are connected by a first rolling shaft 3141 and a first rolling groove 3140. The first rolling shaft 3141 is disposed on one of the rolling portion 314 and the first driven member 71, and the first rolling groove 3140 is disposed on the other of the rolling portion 314 and the first driven member 71.

[0212] In this embodiment, the support portion 313 has a support surface 310 for supporting the component to be supported, and the first rolling groove 3140 has a first limiting end 3140a and a second limiting end 3140b with opposite sides. The first limiting end 3140a is farther away from the bracket 10 than the second limiting end 3140b, and the first limiting end 3140a is farther away from the support surface 310 than the second limiting end.

[0213] In this embodiment, the first rolling groove 3140 also has a first connecting portion 3140c that connects the first limiting end 3140a and the second limiting end 3140b. From the first limiting end 3140a to the first connecting portion 3140c and then to the second limiting end 3140b, the distance between the first rolling groove 3140 and the support surface 310 gradually decreases.

The above description is merely for the purpose of helping to understand the method and core ideas of this application. Furthermore, those skilled in the art will recognize that, based on the ideas of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
