[0002] With the continuous development of display technology, various types of electronic devices have been launched. For example, foldable electronic devices are increasingly popular due to their ability to switch between a small overall size and a large display area. Currently, foldable electronic devices utilize folding mechanisms to achieve their folding function, but these mechanisms currently occupy a significant amount of space, hindering miniaturization. Summary of the Invention

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.

[0044] Please refer to this as well. Figures 1-7 , Figure 1 This is a three-dimensional structural diagram of the folding device in the unfolded state according to one embodiment of this application.

[0045] This embodiment provides a folding device 1, including a bracket 10, two rotating mechanisms 20, two support members 30, and two driven members 40. Each rotating mechanism 20 includes a rotating member 22 and a connecting member 21. One end of the rotating member 22 is rotatably connected to the bracket 10, and the other end of the rotating member 22 is rotatably connected to the connecting member 21. The connecting member 21 is slidably and rotatably connected to the bracket 10. Each support member 30 is rotatably connected to a different connecting member 21. One end of each driven member 40 is rotatably connected to the bracket 10, and the other end of each driven member 40 is slidably and rotatably connected to a different support member 30. The other end of each driven member 40 is also slidably and rotatably connected to a different connecting member 21.

[0046] When the connector 21 rotates relative to the bracket 10, the connector 21 also slides relative to the bracket 10. The rotating member 22 rotates relative to both the bracket 10 and the connector 21. The driven member 40 rotates relative to the bracket 10. The driven member 40 also slides and rotates relative to the connector 21. The driven member 40 also slides and rotates relative to the support member 30.

[0047] 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 3 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.

[0048] Furthermore, the aforementioned electronic device 3 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 is only illustrative when the electronic device 3 is a mobile phone. Of course, in other embodiments, the electronic device 3 can be other types, and they should also fall within the protection scope of this application.

[0049] 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 the rotating component 22 and the driven component 40, to be mounted on the bracket 10. Furthermore, in some embodiments, the bracket 10 can also support a screen. This screen includes, but is not limited to, various screens, 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.

[0050] The rotating mechanism 20 is one of the core mechanisms in the folding device 1. It primarily realizes the rotation function of the folding device 1 and drives the components connected to and limited by the rotating mechanism 20, causing these components to move according to a preset motion trajectory. This embodiment includes two rotating mechanisms 20, which can rotate along the axis of the support 10 (e.g., ...). Figure 3 The two rotating mechanisms 20 are arranged side by side in the direction shown in the middle (O). When the folding device 1 is in the unfolded state, the two rotating mechanisms 20 are located on opposite sides of the support 10. When the folding device 1 is in the folded state, the two rotating mechanisms 20 are located on the same side of the support 10.

[0051] Each rotating mechanism 20 includes a connector 21 and a rotating member 22. The rotating member 22 primarily functions to rotate, while the connector 21 is mainly used for subsequent fixation to the housing 50. The end of the rotating member 22 closest to the support 10 is rotatably connected to the support 10, and the end of the rotating member 22 furthest from the support 10 is rotatably connected to the connector 21. In other words, the rotating member 22 can rotate relative to both the support 10 and the connector 21. The connector 21, on the other hand, can slide and rotate relative to the support 10. In other words, the connector 21 can both slide and rotate relative to the support 10.

[0052] It's important to note that the rotation mentioned above can be understood as two moving parts undergoing circular motion around a rotation axis. Sliding can be understood as two moving parts moving in parallel, with only changes in displacement and no changes in angle. The fact that two moving parts can both slide and rotate means that they experience both changes in displacement and angle; this combination of sliding and rotation can also be called rolling.

[0053] The support member 30 in the folding device 1 is mainly used to support the flexible screen. As a constrained mechanism in the folding device 1, the support member 30 can move under the restriction of the movement trajectory of other components, ultimately achieving the desired folding shape, and thus causing the screen to bend into the required shape. This embodiment includes two support members 30. One support member 30 is rotatably connected to the connector 21 in a rotating mechanism 20, and the other support member 30 is rotatably connected to the connector 21 in another rotating mechanism 20. The support member 30 is rotatably connected to the connector 21, so the support member 30 can rotate relative to the connector 21, thereby providing a basis for the subsequent realization of the teardrop-shaped receiving space 11.

[0054] The follower 40 plays an auxiliary role in the folding device 1, mainly controlling and driving the movement of the support 30 and the connector 21, so that the support 30 moves along a specific trajectory. This embodiment includes two followers 40, one of which is connected to one support 30, and the other is connected to another support 30. Specifically, one end of the follower 40 is rotatably connected to the bracket 10, and the other end is slidably and rotatably connected to the support 30. The other end of the follower 40 is also slidably and rotatably connected to the connector 21. In other words, the end of the follower 40 closer to the bracket 10 can rotate relative to the bracket 10, and the end of the follower 40 farther from the bracket 10 can roll relative to both the support 30 and the connector 21.

[0055] 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 connecting member 21 rotates relative to the bracket 10, the connecting member 21 also slides relative to the bracket 10; the rotating member 22 rotates relative to both the bracket 10 and the connecting member 21; the driven member 40 rotates relative to the bracket 10; the driven member 40 also slides and rotates relative to the connecting member 21; and the driven member 40 also slides and rotates relative to the support member 30.

[0056] The movement process of the aforementioned folding device 1 has various active and passive logical relationships. This embodiment illustrates one specific movement process as an example. When the folding device 1 folds or unfolds, that is, when the connecting member 21 rotates relative to the support 10, the connecting member 21 can also slide relative to the support 10. The movement of the connecting member 21 can drive the rotating member 22 and the support member 30 to rotate relative to the support 10, and at the same time, the rotating member 22 also rotates relative to the connecting member 21. Furthermore, since the driven member 40 rolls to connect the support member 30 and the connecting member 21, when the support member 30 rotates, it can drive the driven member 40 to rotate, and the support member 30 and the connecting member 21 also roll relative to the driven member 40, ultimately causing the two support members 30 to fold or unfold relative to each other. Of course, in other embodiments, the active and passive relationships of the above-mentioned multiple structural members can be reversed. For example, it can also be that the two support members 30 rotate relative to the support 10, thereby driving the connecting member 21 to rotate relative to the support 10. Such movement processes and principles should also fall within the protection scope of this application.

[0057] like Figure 4 As shown, when the two support members 30 are parallel to each other and located on opposite sides of the bracket 10, the two support members 30 are in a fully unfolded state. This can also be understood as the two support members 30 being located on the sides of the bracket 10; in other words, the folding device 1 is in an unfolded state. Figure 7 As shown, when the two support members 30 are parallel to each other and both support members 30 are located on one side of the bracket 10, which can also be understood as both support members 30 being located on the top surface of the bracket 10, the two support members 30 are in a completely folded state; in other words, the folding device 1 is in a folded state. The process of the two support members 30 folding together, i.e., the process of the folding device 1 changing from an unfolded state to a folded state, can also be understood as... Figures 4 to 7 During this process, the two connecting pieces 21 rotate relative to each other and move closer together, causing the two supporting pieces 30 to merge together, thus achieving mutual approach and folding. When the two supporting pieces 30 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... Figures 7 to 4 During this process, the two connecting pieces 21 rotate relative to each other and move away from each other, causing the two supporting pieces 30 to separate from each other, so as to achieve mutual separation and unfolding.

[0058] When the folding device 1 is in the folded state, the two support members 30 and the bracket 10 together form a receiving space 11 for accommodating the flexible screen. The folding device 1 provided in this embodiment can make the cross-sectional shape of the screen U-shaped or teardrop-shaped. This embodiment is only illustrated with the cross-sectional shape of the receiving space 11 being teardrop-shaped.

[0059] The folding device 1 provided in this embodiment achieves the folding and unfolding functions of the two support members 30 by cooperating with the bracket 10, two rotating mechanisms 20, two support members 30, and two driven members 40. Furthermore, the aforementioned connection relationship makes the structure of the folding device 1 compact, thereby reducing the size of the folding device 1 and the internal space occupied by the housing assembly 2 and electronic device 3. This facilitates the layout of other structural components such as the motherboard or battery, and promotes the miniaturization of the folding device 1. In addition, compared to a purely sliding connection, the support members 30 in this application do not need to slide outward relative to the bracket 10, requiring less space, thus further reducing the size of the folding device 1. Moreover, compared to a linear groove design, it effectively supports the middle frame when the folding device 1 is dropped, preventing wobbling and improving the stability and reliability of the folding device 1. In other words, this embodiment provides a four-rotation-center teardrop-shaped inward folding shaft design, achieving a miniaturized teardrop shaft.

[0060] Optionally, the left module located on one side of the bracket 10, consisting of a rotating mechanism 20, a support member 30, and a follower member 40, and the right module located on the other side of the bracket 10, consisting of another rotating mechanism 20, another support member 30, and another follower member 40, can be symmetrically designed or asymmetrically designed.

[0061] Please refer to this as well. Figures 8-10 , Figure 8 This is a schematic diagram showing the cooperation between the connector and the bracket in one embodiment of this application when they are unfolded. Figure 9 for Figure 8 The exploded view of the connector and bracket shown. Figure 10 This is a schematic diagram showing the connection between the connector and the bracket when folded according to one embodiment of this application. In this embodiment, the connector 21 includes a connecting part 211 and a first rolling part 212. One end of the first rolling part 212 is slidably and rotatably connected to the bracket 10, and the other end of the first rolling part 212 is fixed to the connecting part 211.

[0062] One end of the first rolling part 212 is connected to the bracket 10 through a first rolling shaft 213 and a first rolling groove 214. The first rolling shaft 213 is located at one end of the first rolling part 212 and one of the bracket 10, and the first rolling groove 214 is located at one end of the first rolling part 212 and the other of the bracket 10.

[0063] The connector 21 includes a connecting portion 211 and a first rolling portion 212. The connecting portion 211 is used to subsequently connect to the housing 50, and the first rolling portion 212 is used to achieve rolling with the bracket 10. The end of the first rolling portion 212 closest to the bracket 10 slides and rotates to connect to the bracket 10, while the end of the first rolling portion 212 furthest from the bracket 10 is fixed to the connecting portion 211. Therefore, the movement of the first rolling portion 212 causes the connecting portion 211 to move in the same way, thereby causing the housing 50 to perform the same action. The cooperation between the first rolling shaft 213 and the first rolling groove 214 allows one end of the first rolling portion 212 to roll better relative to the bracket 10, thus providing a good foundation for the subsequent formation of the teardrop-shaped receiving space 11.

[0064] Optionally, the connecting part 211 and the first rolling part 212 can be an integral structure or a separate structure.

[0065] One end of the first rolling part 212 can be connected to the bracket 10 via a first rolling shaft 213 and a first rolling groove 214. That is, the first rolling shaft 213 is disposed within the first rolling groove 214, and the rolling of the first rolling shaft 213 within the first rolling groove 214 drives the connected component to roll. When the first rolling shaft 213 is disposed at one end of the first rolling part 212, the first rolling groove 214 is disposed on the bracket 10; or, when the first rolling shaft 213 is disposed on the bracket 10, the first rolling groove 214 is disposed at one end of the first rolling part 212. This embodiment is only illustrated with the example of the first rolling shaft 213 being disposed at one end of the first rolling part 212 and the first rolling groove 214 being disposed on the bracket 10. Optionally, the first rolling shaft 213 and the first rolling part 212 can be an integral structure or a separate structure. Optionally, the first rolling shaft 213 includes, but is not limited to, a pin.

[0066] It is worth noting that this embodiment and the following text only illustrate half of the structure of the folding device 1. In other words, only the structure of the right half of the folding device 1 is illustrated. For example, this embodiment only illustrates one connector 21 located on the right side of the bracket 10. As for the other connector 21 located on the left side of the bracket 10, it can be understood in the same way as the connector 21 in this embodiment. This embodiment will not be described in detail here.

[0067] Please refer to this as well. Figures 9-10 In this embodiment, the first rolling groove 214 has a first limiting end 2141 and a second limiting end 2142 opposite to each other, and the bracket 10 has a bearing surface 100 for bearing the flexible member 70. When the first rolling groove 214 is provided on the bracket 10, the first limiting end 2141 is farther away from the bearing surface 100 than the second limiting end 2142, and the first limiting end 2141 and the second limiting end 2142 are closer to the axis of the bracket 10.

[0068] When the folding device 1 is in the unfolded state, the first rolling shaft 213 is positioned at the first limiting end 2141, and when the folding device 1 is in the folded state, the first rolling shaft 213 is positioned at the second limiting end 2142.

[0069] The first rolling groove 214 has two oppositely arranged ends: a first limiting end 2141 and a second limiting end 2142. Since the first rolling shaft 213 slides within the first rolling groove 214, the sidewalls of the first limiting end 2141 and the second limiting end 2142 can be used to restrict the sliding of the first rolling shaft 213, so that the sliding of the first rolling shaft 213 stops when it reaches the first limiting end 2141 and the second limiting end 2142, and it can no longer continue to slide. Figure 9 As shown, the bracket 10 has a bearing surface 100, i.e., the top surface of the bracket 10, for subsequently supporting the flexible component 70. When the first rolling groove 214 is provided on the bracket 10, the first limiting end 2141 is farther away from the bearing surface 100 than the second limiting end 2142, and the first limiting end 2141 and the second limiting end 2142 are closer to the axis of the bracket 10. It can also be understood that the first limiting end 2141 is lower and more to the left than the second limiting end 2142. Therefore, the first limiting end 2141 is located in the lower left position, and the second limiting end 2142 is located in the upper right position.

[0070] During the entire movement of the folding device 1, when the folding device 1 is in the unfolded state, the first rolling shaft 213 is positioned at the first limiting end 2141 to prevent the rolling part from folding back and being damaged. When the folding device 1 is in the folded state, the first rolling shaft 213 is positioned at the second limiting end 2142 to prevent the rolling part from bending further and being damaged. In other words, when the folding device 1 is fully unfolded, the first rolling shaft 213 is located at the lower left, and when the folding device 1 is fully folded, the first rolling shaft 213 is located at the upper right. Through the above settings, the movement trajectory of each component in the folding device 1 can be further controlled, thereby driving the movement of other components to achieve the teardrop-shaped receiving space 11.

[0071] Please refer to this as well. Figures 9-10 In this embodiment, the first rolling groove 214 further has a first connecting portion 2143 that connects the first limiting end 2141 and the second limiting end 2142, and the first connecting portion 2143 protrudes in a direction away from the bearing surface 100.

[0072] The first rolling groove 214 is a groove of a certain length. Therefore, in addition to the first limiting end 2141 and the second limiting end 2142, the first rolling groove 214 also has a first connecting portion 2143 that connects the first limiting end 2141 and the second limiting end 2142. The first rolling shaft 213 is located in the first connecting portion 2143 in all states except the unfolded state and the folded state. In this embodiment, the first connecting portion 2143 can be made to protrude in a direction away from the bearing surface 100. This makes the movement of the rolling part smoother. During the process of the folding device 1 from the unfolded state to the folded state, when the first rolling shaft 213 just leaves the first limiting end 2141, the first rolling shaft 213 moves to the lower right. Then, when the first rolling shaft 213 moves to the lowest point, it moves to the upper right until the first rolling shaft 213 moves to the second limiting end 2142 and stops moving.

[0073] Of course, in other embodiments, the shape of the first connecting portion 2143 can also be a straight line or other shapes, as long as the first limiting end 2141 and the second limiting end 2142 satisfy the above positional relationship.

[0074] Please refer to Figure 11 , Figure 11 This is a schematic diagram illustrating the cooperation of the bracket, driven member, and rotating member in one embodiment of this application. In this embodiment, the first axis of rotation between one end of the driven member 40 and the bracket 10 is further away from the axis of the bracket 10 than the second axis of rotation between one end of the rotating member 22 and the bracket 10.

[0075] Since both one end of the driven member 40 and one end of the rotating member 22 can rotate relative to the bracket 10, there is a first axis of rotation between one end of the driven member 40 and the bracket 10 (e.g., Figure 11 As shown in C1), one end of the rotating member 22 has a second rotation axis between it and the bracket 10 (as shown in Figure C1). Figure 11 (As shown in C2). In this embodiment, the first rotation axis is further away from the axis of the support 10 than the second rotation axis, that is, the first rotation axis is further to the right than the second rotation axis. In other words, the first rotation axis does not coincide with the second rotation axis and the first rotation axis is further outward.

[0076] Because the two rotation axes are not coincident, when the driven member 40 rotates relative to the bracket 10, it can subsequently cause the support member 30 to slide relative to the driven member 40, thereby achieving the desired motion trajectory. Furthermore, the non-coincidence of the two rotation axes ensures that the connecting member 21 and the support member 30 will not rotate when the folding device 1 is stationary, guaranteeing the stability of the folding device 1. However, through the connection relationship of the aforementioned components, the rotating member 22 and the driven member 40 can also rotate when the folding device 1 rotates, thus avoiding the problem of jamming.

[0077] Optionally, the first axis of rotation between one end of the driven member 40 and the bracket 10 is further away from the bottom surface of the bracket 10 than the second axis of rotation between one end of the rotating member 22 and the bracket 10.

[0078] Please refer to this as well. Figures 12-13 , Figure 12 This is a schematic diagram showing the engagement of the connector and the driven member when they are unfolded according to one embodiment of this application. Figure 13 This is a schematic diagram showing the engagement of the connector and the follower when folded according to one embodiment of this application. In this embodiment, the connector 21 includes a connecting portion 211 and a second rolling portion 215. The second rolling portion 215 is closer to the support member 30 than the connecting portion 211. The other end of the follower 40 is slidably and rotatably connected to the second rolling portion 215.

[0079] The other end of the driven member 40 is connected to the second rolling part 215 through a second rolling shaft 216 and a second rolling groove 217. The second rolling shaft 216 is located at one of the other end of the driven member 40 and the second rolling part 215, and the second rolling groove 217 is located at the other end of the driven member 40 and the second rolling part 215.

[0080] The connector 21 includes a connecting portion 211 and a second rolling portion 215. The connecting portion 211 is used for subsequent connection to the housing 50, and the second rolling portion 215 is used to roll with the other end of the driven member 40. In addition, the second rolling portion 215 is closer to the support member 30 than the connecting portion 211. In other words, the second rolling portion 215 is located above the connecting portion 211, or it can be understood that the second rolling portion 215 is sandwiched between the connecting portion 211 and the support member 30.

[0081] Specifically, the other end of the driven member 40 is connected to the second rolling part 215 via a second rolling shaft 216 and a second rolling groove 217, thereby allowing the other end of the driven member 40 to slide and rotate in connection with the second rolling part 215. When the second rolling shaft 216 is located at the other end of the driven member 40, the second rolling groove 217 is located at the second rolling part 215. This embodiment is only illustrated with the second rolling shaft 216 located at the other end of the driven member 40 and the second rolling groove 217 located at the second rolling part 215. The cooperation between the second rolling shaft 216 and the second rolling groove 217 allows the second rolling part 215 to roll better relative to the driven member 40, thus providing a good foundation for the subsequent formation of the teardrop-shaped receiving space 11.

[0082] Optionally, the second rolling shaft 216 and the other end of the follower 40 can be an integral structure or a separate structure. Optionally, the second rolling shaft 216 includes, but is not limited to, a pin. By providing the second rolling shaft 216 and the second rolling groove 217 on the other end of the follower 40 and the second rolling portion 215, the structure can be simplified, allowing the other end of the follower 40 to roll better relative to the second rolling portion 215.

[0083] Please refer to this again. Figures 12-13 In this embodiment, the second rolling groove 217 has a third limiting end 2171 and a fourth limiting end 2172 that are disposed opposite to each other. When the second rolling groove 217 is disposed on the second rolling part 215, the third limiting end 2171 is closer to the support member 30 than the fourth limiting end 2172, and the third limiting end 2171 is farther away from the bracket 10 than the fourth limiting end 2172.

[0084] When the folding device 1 is in the unfolded state, the second rolling shaft 216 is positioned at the third limiting end 2171, and when the folding device 1 is in the folded state, the second rolling shaft 216 is positioned at the fourth limiting end 2172.

[0085] The second rolling groove 217 has two oppositely arranged ends: a third limiting end 2171 and a fourth limiting end 2172. Since the second rolling shaft 216 slides within the second rolling groove 217, the sidewalls of the third limiting end 2171 and the fourth limiting end 2172 can be used to restrict the sliding of the second rolling shaft 216, causing it to stop sliding when it reaches the third limiting end 2171 and the fourth limiting end 2172, preventing it from continuing to slide. When the second rolling groove 217 is located on the second rolling part 215, specifically, the third limiting end 2171 is closer to the support member 30 than the fourth limiting end 2172, and the third limiting end 2171 is farther away from the bracket 10 than the fourth limiting end 2172. In other words, the third limiting end 2171 is located in the upper right position, and the fourth limiting end 2172 is located in the lower left position.

[0086] During the entire movement of the folding device 1, when the folding device 1 is in the unfolded state, the second rolling shaft 216 is positioned at the third limiting end 2171 to prevent the second rolling part 215 from folding back and being damaged. When the folding device 1 is in the folded state, the second rolling shaft 216 is positioned at the fourth limiting end 2172 to prevent the second rolling part 215 from bending further and being damaged. In other words, when the folding device 1 is fully unfolded, the second rolling shaft 216 is located at the lower right, and when the folding device 1 is fully folded, the second rolling shaft 216 is located at the upper left. By designing the shape of the second rolling groove 217 as described above, the connecting part 211 can move along a predetermined trajectory, ultimately achieving the formation of a teardrop-shaped receiving space 11 when folded.

[0087] Optionally, the second rolling groove 217 also has a second connecting portion 2173 that connects the third limiting end 2171 and the fourth limiting end 2172. In this embodiment, the shape of the second connecting portion 2173 can be straight, thereby reducing the overall size of the folding device 1.

[0088] Please refer to this as well. Figures 14-15 , Figure 14 This is a schematic diagram of the cooperation between the support member and the driven member in one embodiment of this application when they are deployed. Figure 15 This is a schematic diagram illustrating the engagement of the support member and the driven member when folded according to one embodiment of this application. In this embodiment, the support member 30 includes a support portion 31 and a third rolling portion 32. The support portion 31 has a support surface 310 for supporting the flexible member 70, and the third rolling portion 32 is disposed on the side of the support portion 31 opposite to the support surface 310.

[0089] The other end of the driven member 40 is connected to the third rolling part 32 via a third rolling shaft 321 and a third rolling groove 322. The third rolling shaft 321 is located at one of the other end of the driven member 40 and the third rolling part 32, and the third rolling groove 322 is located at the other end of the driven member 40 and the third rolling part 32.

[0090] The support member 30 includes a support portion 31 and a third rolling portion 32. The support portion 31 is subsequently used to support the flexible member 70, and therefore has a support surface 310 for supporting the flexible member 70, that is, the upper surface of the support portion 31 is the support surface 310. The third rolling portion 32 is used to roll with the other end of the driven member 40. In addition, the third rolling portion 32 is provided on the side of the support portion 31 away from the support surface 310, in other words, the third rolling portion 32 is provided on the lower surface of the support portion 31.

[0091] Specifically, the other end of the driven member 40 is connected to the third rolling part 32 via a third rolling shaft 321 and a third rolling groove 322, thereby allowing the other end of the driven member 40 to slide and rotate in connection with the third rolling part 32. When the third rolling shaft 321 is located at the other end of the driven member 40, the third rolling groove 322 is located at the third rolling part 32. This embodiment is only illustrated with the third rolling shaft 321 located at the other end of the driven member 40 and the third rolling groove 322 located at the third rolling part 32. Optionally, the third rolling shaft 321 and the other end of the driven member 40 can be an integral structure or a separate structure. Optionally, the third rolling shaft 321 includes, but is not limited to, a pin.

[0092] The structure can be simplified by providing a third rolling shaft 321 and a third rolling groove 322 on the other end of the follower 40 and the third rolling part 32, so that the other end of the follower 40 can roll better relative to the third rolling part 32, providing a good foundation for the subsequent formation of the teardrop-shaped receiving space 11.

[0093] Please refer to this again. Figures 14-15 In this embodiment, the third rolling groove 322 has a fifth limiting end 3221 and a sixth limiting end 3222 that are disposed opposite to each other. When the third rolling groove 322 is disposed on the third rolling part 32, the fifth limiting end 3221 is closer to the support surface 310 than the sixth limiting end 3222, and the fifth limiting end 3221 is farther away from the bracket 10 than the sixth limiting end 3222.

[0094] When the folding device 1 is in the unfolded state, the third rolling shaft 321 is positioned at the fifth limiting end 3221. When the folding device 1 is in the folded state, the third rolling shaft 321 is positioned at the sixth limiting end 3222.

[0095] The third rolling groove 322 has two oppositely arranged ends: a fifth limiting end 3221 and a sixth limiting end 3222. Since the third rolling shaft 321 slides within the third rolling groove 322, the sidewalls of the fifth limiting end 3221 and the sixth limiting end 3222 can be used to restrict the sliding of the third rolling shaft 321, causing it to stop sliding when it reaches the fifth limiting end 3221 and the sixth limiting end 3222, preventing it from continuing to slide. When the third rolling groove 322 is located on the third rolling part 32, specifically, the fifth limiting end 3221 is closer to the support surface 310 than the sixth limiting end 3222, and the fifth limiting end 3221 is farther from the bracket 10 than the sixth limiting end 3222. In other words, the fifth limiting end 3221 is located in the upper right position, and the sixth limiting end 3222 is located in the lower left position.

[0096] During the entire movement of the folding device 1, when the folding device 1 is in the unfolded state, the third rolling shaft 321 is positioned at the fifth limiting end 3221 to prevent the third rolling part 32 from folding back and being damaged. When the folding device 1 is in the folded state, the third rolling shaft 321 is positioned at the sixth limiting end 3222 to prevent the third rolling part 32 from bending further and being damaged. In other words, when the folding device 1 is fully unfolded, the third rolling shaft 321 is located at the lower right, and when the folding device 1 is fully folded, the third rolling shaft 321 is located at the upper left. By designing the shape of the third rolling groove 322 as described above, the connecting part 211 can move along a predetermined trajectory, ultimately forming a teardrop-shaped receiving space 11 when folded. In addition, tilting the third rolling groove 322 can reduce the thickness of the driven member 40, thereby further reducing the overall thickness of the folding device 1.

[0097] Optionally, the third rolling groove 322 also has a third connecting portion 3223 that connects the fifth limiting end 3221 and the sixth limiting end 3222. In this embodiment, the shape of the third connecting portion 3223 can be a straight line, thereby reducing the overall size of the folding device 1.

[0098] Please refer to Figure 16 , Figure 16This is a three-dimensional structural diagram of the follower in one embodiment of this application. In this embodiment, when the second rolling shaft 216 and the third rolling shaft 321 are both located at the other end of the follower 40, the axis of the second rolling shaft 216 coincides with the axis of the third rolling shaft 321. In other words, the extending direction of the second rolling shaft 216 is the same as the extending direction of the third rolling shaft 321. Optionally, the second rolling shaft 216 and the third rolling shaft 321 are an integral structure, that is, the second rolling shaft 216 and the third rolling shaft 321 are composed of different parts of the same shaft. This not only simplifies the structure of the follower 40, but also reduces the design difficulty of the second rolling groove 217 and the third rolling groove 322. Furthermore, ensuring that the second rolling shaft 216 and the third rolling shaft 321 have the same concentricity can guarantee the stability of the folding device 1 during movement and prevent jamming.

[0099] Please refer to Figure 17 , Figure 17 This is an exploded view of the follower and the bracket in one embodiment of this application. In this embodiment, one end of the follower 40 is connected to the bracket 10 via a first rotating shaft 401 and a first rotating hole 402. The first rotating shaft 401 is located at one end of the follower 40 and the bracket 10, and the first rotating hole 402 is located at the other end of the follower 40 and the bracket 10.

[0100] As can be seen from the above, one end of the driven member 40 is rotatably connected to the bracket 10. In this embodiment, one end of the driven member 40 and the bracket 10 are connected through a first rotating shaft 401 and a first rotating hole 402. When the first rotating shaft 401 is located at one end of the driven member 40, the first rotating hole 402 is located in the bracket 10; when the first rotating shaft 401 is located in the bracket 10, the first rotating hole 402 is located at one end of the driven member 40. This embodiment is only illustrated with the first rotating shaft 401 located at one end of the driven member 40 and the first rotating hole 402 located in the bracket 10. The above design only requires the first rotating hole 402 to be opened in the bracket 10, without the need to set an arc-shaped sliding groove. Therefore, the size of the bracket 10 can be reduced, the overall size of the folding device 1 can be reduced, and the miniaturization of the folding device 1 can be achieved. Furthermore, the size and clearance of the rotation method of the first rotating shaft 401 and the first rotating hole 402 are better controlled, reducing the risk of the folding device 1 shaking during movement. In addition, by connecting one end of the follower 40 to the bracket 10 through the first rotating shaft 401 and the first rotating hole 402, the thickness of the folding device 1 can be further reduced compared to using an arc rail and an arc groove.

[0101] It is worth noting that the first rotating hole 402 mentioned in this embodiment can be a through hole or a blind hole. A through hole refers to the first rotating hole 402 penetrating both opposite surfaces of the structural member, while a blind hole refers to the first rotating member 22 penetrating only one surface of the structural member. Therefore, a blind hole can also be called a groove.

[0102] Optionally, in some embodiments, the two first rotation axes 401 located on opposite sides of the bracket 10 are arranged symmetrically about the bracket 10. In other embodiments, the two first rotation axes 401 may also be arranged asymmetrically, for example, the two axis lines of the two first rotation axes 401 are arranged to coincide with each other.

[0103] Please refer to Figure 18 , Figure 18 This is an exploded view of the rotating component and the support in one embodiment of this application. In this embodiment, one end of the rotating component 22 is connected to the support 10 via a first arc track 221 and a first arc groove 222. The first arc track 221 is located at one end of the rotating component 22 and the support 10, and the first arc groove 222 is located at the other end of the rotating component 22 and the support 10.

[0104] As can be seen from the above, one end of the rotating member 22 is rotatably connected to the bracket 10. In this embodiment, one end of the rotating member 22 and the bracket 10 are connected by a first arc track 221 and a first arc groove 222. When the first arc track 221 is located at one end of the rotating member 22, the first arc groove 222 is located on the bracket 10; when the first arc track 221 is located on the bracket 10, the first arc groove 222 is located at one end of the rotating member 22. This embodiment is only illustrated by the first arc track 221 being located at one end of the rotating member 22 and the first arc groove 222 being located on the bracket 10. Through the above arrangement, the position of the second rotation axis between one end of the rotating member 22 and the bracket 10 can be better controlled, thereby better ensuring that the first rotation axis and the second rotation axis satisfy the above relationship. For example, in this embodiment, the second rotation axis can be located outside the bracket 10; of course, in other embodiments, the second rotation axis can also be located inside the bracket 10. Furthermore, the thickness of the bracket 10 itself can be used to provide a basis for the arrangement of the arc track and the arc groove.

[0105] By connecting one end of the driven member 40 to the bracket 10 through a first rotating shaft 401 and a first rotating hole 402, and connecting one end of the rotating member 22 to the bracket 10 through a first arc track 221 and a first arc groove 222, the structural design can be improved. The arc groove and arc track are designed on the thicker bracket 10, and the rotating shaft and rotating hole are designed in the smaller space, thereby reducing the thickness of the folding device 1.

[0106] Optionally, the bracket 10 includes a first sub-bracket and a second sub-bracket, which can be an integral structure or a separate structure. In other words, the first arc groove 222 is formed by the cooperation of the first sub-bracket and the second sub-bracket. Further optionally, the first sub-bracket and the second sub-bracket can be split horizontally or vertically.

[0107] Please refer to Figure 19 , Figure 19 This is an exploded view of the rotating member and the connecting member according to one embodiment of this application. In this embodiment, the other end of the rotating member 22 is connected to the connecting member 21 via a second rotating shaft 231 and a second rotating hole 232. The second rotating shaft 231 is located at one of the other end of the rotating member 22 and the connecting member 21, and the second rotating hole 232 is located at the other end of the rotating member 22 and the connecting member 21.

[0108] As can be seen from the above, the other end of the rotating member 22 is rotatably connected to the connecting member 21. Therefore, in this embodiment, the other end of the rotating member 22 and the connecting member 21 can be connected through a second rotating shaft 231 and a second rotating hole 232. When the second rotating shaft 231 is located at the other end of the rotating member 22, the second rotating hole 232 is located in the connecting member 21; when the second rotating shaft 231 is located in the connecting member 21, the second rotating hole 232 is located at the other end of the rotating member 22. This embodiment is only illustrated with the second rotating shaft 231 located at the other end of the rotating member 22 and the second rotating hole 232 located in the connecting member 21. The above design only requires the second rotating hole 232 to be opened in the connecting member 21, without the need to set an arc-shaped sliding groove. Therefore, the size of the connecting member 21 can be reduced, the overall size of the folding device 1 can be reduced, and the miniaturization of the folding device 1 can be achieved. Furthermore, the size and clearance of the rotating mechanism of the second rotating shaft 231 and the second rotating hole 232 are better controlled, reducing the risk of the folding device 1 shaking during movement. Furthermore, by connecting the other end of the rotating component 22 to the connecting component 21 through the second rotating shaft 231 and the second rotating hole 232, the thickness of the folding device 1 can be further reduced compared to using an arc track and an arc groove.

[0109] It is worth noting that the second rotating hole 232 mentioned in this embodiment can be a through hole or a blind hole. A through hole refers to the second rotating hole 232 penetrating both opposite surfaces of the structural member, while a blind hole refers to the second rotating member 22 penetrating only one surface of the structural member. Therefore, a blind hole can also be called a groove.

[0110] Please refer to Figure 20 , Figure 20This is an exploded view of the support member and the connector according to one embodiment of this application. In this embodiment, the support member 30 includes a support portion 31 and a rotating portion. The support portion 31 has a support surface 310 for supporting the flexible member 70, and the rotating portion is located on the side of the support portion 31 opposite to the support surface 310.

[0111] The rotating part and the connecting member 21 are connected by a second arc track 331 and a second arc groove 332. The second arc track 331 is provided on one of the rotating part and the connecting member 21, and the second arc groove 332 is provided on the other of the rotating part and the connecting member 21.

[0112] The support member 30 may include a support portion 31 and a rotating portion. The support portion 31 is subsequently used to support the flexible member 70, and therefore the support portion 31 has a support surface 310 for supporting the flexible member 70, that is, the upper surface of the support portion 31 is the support surface 310. The rotating portion is used to cooperate with the rotating member 22 to realize the rotatable connection between the support member 30 and the connecting member 21. The rotating portion is located on the side of the support portion 31 away from the support surface 310, that is, the rotating portion is located on the lower surface of the support portion 31.

[0113] In this embodiment, the rotating part and the connecting member 21 are connected by a second arc-shaped rail 331 and a second arc-shaped groove 332. When the second arc-shaped rail 331 is located on the rotating part, the second arc-shaped groove 332 is located on the connecting member 21; conversely, when the second arc-shaped rail 331 is located on the connecting member 21, the second arc-shaped groove 332 is located on the rotating part. This embodiment is only illustrated with the second arc-shaped rail 331 located on the connecting member 21 and the second arc-shaped groove 332 located on the rotating part. This arrangement allows for better control of the position of the rotation axis between the rotating part and the connecting member 21, thereby better cooperating with the slider and the groove so that the rotating part rotates when the sliding part slides.

[0114] Please refer to this as well. Figures 21-22 , Figure 21 This is a three-dimensional structural diagram of the housing assembly in the unfolded state according to one embodiment of this application. Figure 22 This is a three-dimensional structural diagram of the housing assembly in a folded state according to one embodiment of this application. This embodiment provides a housing assembly 2, which includes two housings 50 and a folding device 1 as provided in the above embodiment of this application. A connector 21 in the folding device 1 is fixed to the housing 50, and different connectors 21 are fixed to different housings 50. When the housing 50 rotates relative to the support 10, the connector 21 also rotates relative to the support 10.

[0115] The housing assembly 2 is a modular component, meaning it comprises at least two parts. In this embodiment, the housing assembly 2 mainly includes the housing 50 and the folding device 1 described in the above embodiment. The housing 50 is mainly used for mounting and supporting structural components. For example, it can support the component to be connected 21, and it can house structural components such as circuit boards, batteries, and cameras. Therefore, the housing 50 primarily serves for mounting and protection. In some embodiments, the surface of the housing 50 can also serve as an appearance surface, so the surface of the housing 50 can be designed accordingly to give it a unique external appearance. This embodiment does not limit the shape, material, structure, or other parameters of the housing 50, as long as it can achieve the functions of mounting and protection. For example, the material of the housing 50 can be entirely metal, entirely plastic, or partially metal and partially plastic.

[0116] The connector 21 of the folding device 1 is fixed to the housing 50. In other words, the housing 50 and the connector 21 can be an integral structure or a separate structure. At least a portion of the two housings 50 are located on opposite sides of the folding device 1. In some embodiments, all of the two housings 50 may be located on opposite sides of the folding device 1, for example, each housing 50 may be located on a side of the support 10. In other embodiments, portions of the two housings 50 may be located on opposite sides of the folding device 1, while the remaining portions may be located on other sides of the folding device 1. For example, a portion of each housing 50 may be located on a side of the support 10, with the remainder located on the bottom surface of the support 10.

[0117] When the housing 50 is fixed on the connector 21, when the housing 50 is subjected to an external force applied by the user or an external force given by other mechanisms, the housing 50 rotates and drives the connector 21 to rotate. The rotation of the connector 21 can complete the above-mentioned various movement processes until the two housings 50 and the two support members 30 are bent into a teardrop shape or unfolded into a horizontal shape.

[0118] The housing assembly 2 provided in this embodiment can realize the folding and unfolding functions of the housing assembly 2 by adopting the folding device 1 provided in the above embodiment of this application, making the housing assembly 2 more compact and realizing the development of miniaturization.

[0119] In this embodiment, the housing assembly 2 also includes a decorative element 60, and the bracket 10 is fixed on the decorative element 60. The decorative element 60 can serve as the exterior surface of the housing assembly 2 and is used to install the bracket 10 and other components. It can effectively protect the bracket 10 and prevent users from seeing the internal structure of the housing assembly 2 from the outside.

[0120] Please refer to this as well. Figures 23-24 , Figure 23 This is a three-dimensional structural diagram of the electronic device in the unfolded state according to one embodiment of this application. Figure 24This is a three-dimensional structural diagram of an electronic device in a folded state according to one embodiment of this application. This embodiment provides an electronic device 3, which includes a flexible member 70 and a housing assembly 2 as provided in the above embodiment of this application. The flexible member 70 is disposed on two housings 50 and two support members 30 in the folding device 1.

[0121] When the electronic device 3 is folded, the two housings 50 fold together, the two support members 30 fold together, and the two ends of the flexible member 70 fold together. When the electronic device 3 is unfolded, the two housings 50 unfold together, the two support members 30 unfold together, and the two ends of the flexible member 70 unfold together.

[0122] The electronic device 3 includes a flexible component 70 and a housing assembly 2. The flexible component 70 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 70 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 70 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 70 has a bending area 71 and non-bending areas 72 located on opposite sides of the bending area 71. The flexible component 70 in the bending area 71 is correspondingly attached to the folding device 1, and the flexible component 70 in the non-bending area 72 is correspondingly fixed to the housing 50. Since the flexible component 70 in the bending area 71 is correspondingly attached to the folding device 1, the shape of the folding device 1 changes when it moves, thus causing the flexible component 70 in the bending area 71 to bend as well, thereby bending or flattening along with the movement of the electronic device 3. Since the non-bending area 72 is fixed on the housing 50, the housing 50 will only undergo relative rotational movement, and the housing 50 itself will not change shape. Therefore, even if the housing 50 rotates, the flexible part 70 on the housing 50 will not bend.

[0123] The electronic device 3 also has an unfolded state and a folded state. The unfolded state refers to the state where the two support members 30 are fully unfolded, which can also be understood as the state where the flexible member 70 is flattened, or the state where the display surface of the flexible member 70 is flush. The folded state refers to the state where the two support members 30 are fully folded, which can also be understood as the state where the flexible member 70 is bent and the two halves of the flexible member 70 are close to each other, or the state where the display surface of the flexible member 70 is bent. When the electronic device 3 wants to go from the unfolded state to the folded state, that is, when the electronic device 3 needs to be bent, it is only necessary to push or pull the housing 50 towards the center of the electronic device 3 to make the housing 50 rotate. During the rotation of the housing 50, the connecting member 21 and the flexible member 70 fixed on the housing 50 will also rotate. Finally, after the housing 50 rotates 90°, the flexible members 70 in the non-bending areas 72 of the two housings 50 abut against each other, so that the electronic device 3 has no gap between the two housings 50 and can achieve complete abutment. This not only effectively protects the flexible member 70 but also reduces the thickness of the electronic device 3. The flexible element 70 of the bending area 71 on the folding device 1 forms a teardrop shape that is smaller at the top and larger at the bottom.

[0124] When the electronic device 3 wants to return from the folded state to the unfolded state, the user only needs to pull the housing 50 outwards to make the housing 50 rotate. During the rotation of the housing 50, the connecting piece 21 and the flexible piece 70 fixed on the housing 50 will also rotate. Finally, after the housing 50 rotates 90° in the opposite direction, the two supporting pieces 30 return to the fully unfolded state, and the flexible piece 70 also returns to its flat shape.

[0125] The electronic device 3 provided in this embodiment, by adopting the housing component 2 provided in the above embodiment of this application, can realize the folding and unfolding functions of the electronic device 3, making the electronic device 3 more compact and realizing the development of miniaturization.

[0126] The above provides a detailed description of the embodiments provided in this application. This document elucidates and explains the principles and implementation methods of this application. The above description is only intended to help understand the methods and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
