Technical Field

[0001] Embodiments of the present application relate to the technical field of electronic devices, and in particular, to a folding module and a foldable electronic device. Background Art

[0002] With the gradual development of folding screen technology, foldable electronic devices have emerged. A foldable electronic device includes a first support member, a second support member, and a folding screen. The folding screen covers the first support member and the second support member. The first support member and the second support member are connected by a folding module so that the first support member can rotate relative to the second support member, thereby realizing the folding and unfolding of the folding screen.

[0003] In related technologies, the folding module includes a housing, a first rotating shaft and a second rotating shaft rotatably connected to the housing. The first rotating shaft and the second rotating shaft are arranged in parallel and at intervals. A first connecting member is arranged on the first rotating shaft, and the first connecting member is connected to the first support member. A second connecting member is arranged on the second rotating shaft, and the second connecting member is connected to the second support member. During the folding or unfolding process, the first support member rotates relative to the second support member. At the same time, the first rotating shaft and the second rotating shaft rotate relative to the housing.

[0004] However, during the folding process, the first support member rotates relative to the second support member, so that the folding screen covering the first support member and the second support member is stretched or compressed, which easily causes damage to the folding screen. Summary of the Invention

[0005] In view of this, embodiments of the present application provide a folding module and a foldable electronic device to solve the technical problem that the folding screen covering the first support member and the second support member is stretched or compressed, which easily causes damage to the folding screen.

[0006] Embodiments of the present application provide a folding module, including: a fixing member, a first connecting member, and a second connecting member. A first arc-shaped groove is arranged on a preset surface of the fixing member. The first connecting member has a first arc-shaped plate. A first inner tooth is arranged on the inner side of the first arc-shaped plate facing its center line. The first arc-shaped plate is slidably arranged in the first arc-shaped groove. A first rotating shaft is rotatably arranged on the fixing member. A first driving gear is arranged on the first rotating shaft, and the first driving gear meshes with the first inner tooth. The second connecting member is connected to the fixing member.

[0007] With the above settings, during the folding or unfolding process of the foldable electronic device, the first support member rotates relative to the second support member. At this time, the first support member drives the first connecting member to rotate, and the first arc-shaped plate slides around the center line of the first arc-shaped groove in the first arc-shaped groove, so that the first arc-shaped plate gradually slides into the first arc-shaped groove or gradually slides out of the first arc-shaped groove, thereby changing the distance between the first connecting member and the fixing member, and thus avoiding the folding screen covering the first support member and the second support member from being stressed during the folding or unfolding process, and thus avoiding damage to the folding screen.

[0009] With such settings, during the folding or unfolding process, when the first arc-shaped plate slides out of the first arc-shaped groove, the second arc-shaped plate slides out of the second arc-shaped groove at the same time; similarly, when the first arc-shaped plate gradually slides into the first arc-shaped groove, the second arc-shaped plate gradually slides into the second arc-shaped groove; the adjustment amount of the distance between the first support member and the second support member is increased to further avoid the folding screen from being stressed and damaged.

[0096] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0097] A foldable electronic device generally includes a housing and a foldable screen covering the housing. The housing includes a first support member and a second support member. The first support member and the second support member are connected by a folding module so that when folding, the first support member rotates relative to the second support member, thereby driving the foldable screen to bend. The folding module includes a housing, a first rotating shaft and a second rotating shaft rotatably connected to the housing. The center lines of the first rotating shaft and the second rotating shaft are arranged in parallel; a first connecting member is provided on the first rotating shaft, and the first connecting member is connected to the first support member by means of a bolt connection. A second connecting member is provided on the second rotating shaft, and the second connecting member is connected to the second support member by means of a bolt connection.

[0098] However, when folding or unfolding, the first support member rotates relative to the second support member. At this time, the foldable screen covering the first support member and the second support member is easily stretched or compressed, which is likely to cause damage to the foldable screen.

[0099] This embodiment provides a foldable electronic device. A first arc-shaped groove is provided on a fixing member, and a first arc-shaped plate is provided on a first connecting member. The first arc-shaped plate is slidably disposed in the first arc-shaped groove. A first internal tooth is provided on the inner side of the first arc-shaped plate. A first rotating shaft is rotatably provided on the fixing member, and a first driving gear meshing with the first internal tooth is provided on the first rotating shaft. When folding or unfolding, the first supporting member drives the first connecting member to rotate. At the same time, the first arc-shaped plate gradually slides into the first arc-shaped groove or gradually slides out of the first arc-shaped groove. During the rotation, the distance between the first supporting member and the second supporting member can be adjusted, thereby reducing the force on the folding screen during the rotation and avoiding damage to the folding screen.

[0100] The foldable electronic device provided in this embodiment can be a foldable mobile phone, a foldable tablet computer, a laptop computer, or other foldable electronic devices.

[0101] The foldable electronic device provided in this embodiment includes a first supporting member, a second supporting member, and a folding screen covering the first supporting member and the second supporting member. Among them, the first supporting member and the second supporting member can be the outer casings of the foldable electronic device. Further, the folding screen covers the first supporting member and the second supporting member. Exemplarily, the folding screen can cover the inner sides of the first supporting member and the second supporting member. That is to say, when the first supporting member and the second supporting member are folded together, the folding screen is located between the first supporting member and the second supporting member, and at this time, the folding screen is difficult to observe from the outside. Of course, the folding screen can also cover the outer sides of the first supporting member and the second supporting member. That is to say, when the first supporting member and the second supporting member are folded together, the folding screen is located outside the first supporting member and the second supporting member, and at this time, the folding screen can still be touched from the outside.

[0102] Further, the folding screen can be a foldable liquid crystal display (LCD) or a foldable organic light-emitting diode display (OLED). This embodiment does not limit the folding screen.

[0103] Please refer to Figure 1 and Figure 2The first support member and the second support member are connected by a folding module to realize the connection between the first support member and the second support member, and the folding or unfolding of the first support member and the second support member can be realized by the folding module. The folding module includes a fixing member 30, which can be arranged between the first support member and the second support member, and a first arc groove 301 is arranged on the preset surface of the fixing member 30. The folding module also includes a first connecting member 10 connected to the first support member, and a second connecting member 20 connected to the second support member, and a first arc plate 101 is arranged on the first connecting member 10, and the first arc plate 101 is slidably arranged in the first arc groove 301, and the groove bottom of the first arc groove 301 contacts the outer side surface of the first arc plate 101 away from its center line, and the diameter of the arc-shaped outer side surface of the first arc plate 101 is equal to the diameter of the first arc groove 301, so that when the first support member drives the first connecting member 10 to rotate, the first arc plate 101 can slide in the first arc groove 301.

[0104] A first rotating shaft 40 is rotatably provided on the fixing member 30, and a first driving gear 401 is provided on the first rotating shaft 40. At least a portion of the first driving gear 401 is located in the first arc groove 301, and the first driving gear 401 is meshed with the first internal teeth 102. The first driving gear 401 is meshed with the internal teeth, and when the first connecting member 10 rotates and drives the first arc plate 101 to slide around the center line of the first arc groove 301 in the first arc groove 301, the first arc plate 101 can be restricted in the first arc groove 301, thereby preventing the first arc plate 101 from separating from the fixing member 30.

[0105] With such arrangement, when the foldable electronic device is folded or unfolded, the first support member rotates relative to the second support member. At this time, the first support member drives the first connecting member 10 to rotate, and the first arc plate 101 slides in the first arc groove 301 around the center line of the first arc groove 301, so that the first arc plate 101 gradually slides into the first arc groove 301, or gradually slides out of the first arc groove 301, thereby changing the distance between the first connecting member 10 and the fixing member 30, thereby avoiding the folding screen covering the first support member and the second support member from being subjected to force during the folding or unfolding process, thereby avoiding damage to the folding screen.

[0106] Exemplarily, the first drive gear 401 can be an integral structure with the first rotating shaft 40, in which case the first drive gear 401 and the first rotating shaft 40 constitute a gear shaft; of course, the first drive gear 401 can also be connected to the first rotating shaft 40 by a key connection, which is not limited in this embodiment.

[0107] In this embodiment, the first connecting member 10 may be in the shape of a plate. Correspondingly, the first arc-shaped plate 101 is provided at one end of the first connecting member 10 and extends outward from the first connecting member 10. The first connecting member 10 can be connected to the first support member by means of bolt connection or snap connection.

[0108] In this embodiment, the second connecting member 20 is connected to the fixing member 30. Exemplarily, the second connecting member 20 can be connected to the fixing member 30 by means of bolt connection or snap connection. Of course, the second connecting member 20 and the fixing member 30 can also be an integral structure.

[0109] In some embodiments, the connection manner between the second connecting member 20 and the fixing member 30 is substantially the same as the connection manner between the first connecting member 10 and the fixing member 30. Exemplarily, continuing to refer to Figure 1 and Figure 2 , a second arc-shaped groove 302 is further provided on the preset surface of the fixing member 30. The center line of the second arc-shaped groove 302 is arranged parallel to the center line of the first arc-shaped groove 301, and the plane where the second arc-shaped groove 302 is located is spaced from the plane where the first arc-shaped groove 301 is located. Further, the center lines of the first arc-shaped groove 301 and the second arc-shaped groove 302 can be collinearly arranged. Correspondingly, a second arc-shaped plate 201 is provided on the second connecting member 20. The second arc-shaped plate 201 slides in the second arc-shaped groove 302, and a second inner tooth 202 is provided on the inner side of the second arc-shaped plate 201 facing its center line. A second rotating shaft 50 is rotatably provided on the fixing member 30. A second driving gear 501 is provided on the second rotating shaft 50. At least part of the second driving gear 501 is located in the second sliding groove 5032. The second driving gear 501 meshes with the second inner tooth 202. When the second connecting member 20 rotates relative to the first connecting member 10, the second connecting member 20 drives the second arc-shaped plate 201 to slide in the second arc-shaped groove 302 around the center line of the second arc-shaped groove 302. At the same time, the second driving gear 501 can limit the second arc-shaped plate 201 in the second arc-shaped groove 302 to prevent the second arc-shaped plate 201 from separating from the fixing member 30.

[0110] With such a setting, during the folding or unfolding process, while the first arc-shaped plate 101 slides out of the first arc-shaped groove 301, the second arc-shaped plate 201 slides out of the second arc-shaped groove 302. Similarly, while the first arc-shaped plate 101 gradually slides into the first arc-shaped groove 301, the second arc-shaped plate 201 gradually slides into the second arc-shaped groove 302. The adjustment amount of the distance between the first support member and the second support member is increased to further prevent the folding screen from being damaged by force.

[0111] As Figure 3As shown, in the above implementation, when the first support member and the second support member are unfolded, that is, when the first support member and the second support member are in the same plane, the first arc-shaped plate 101 can completely slide into the first arc-shaped groove 301, and the same second arc-shaped plate 201 completely slides into the second arc-shaped groove 302; when the first support member and the second support member are folded together, a part of the first arc-shaped plate 101 slides out of the first arc-shaped groove 301, and a part of the second arc-shaped plate 201 slides out of the second arc-shaped groove 302.

[0112] In the electronic device provided in this embodiment, a first arc-shaped groove 301 is provided on the fixing member 30, a first arc-shaped plate 101 is provided on the first connecting member 10, a first internal tooth 102 is provided on the inner side of the second arc-shaped plate 201, and the first arc-shaped plate 101 is slidably arranged in the first arc-shaped groove 301; the first rotating shaft 40 is rotatably connected to the fixing member 30, and a second driving gear 501 meshing with the first internal tooth 102 is provided on the first rotating shaft 40; during the folding or unfolding process of the foldable electronic device, the first support member rotates relative to the second support member. At this time, the first support member drives the first connecting member 10 to rotate, and the first arc-shaped plate 101 slides around the center line of the first arc-shaped groove 301 in the first arc-shaped groove 301, so that the first arc-shaped plate 101 gradually slides into the first arc-shaped groove 301 or gradually slides out of the first arc-shaped groove 301, thereby changing the distance between the first connecting member 10 and the fixing member 30, avoiding the folding screen covering the first support member and the second support member from being stressed during the folding or unfolding process, and thus avoiding damage to the folding screen.

[0113] Continue to refer to Figure 1 and Figure 2 , in this embodiment, a receiving groove 303 is further provided on the preset surface of the fixing member 30. The receiving groove 303 is located between the first arc-shaped groove 301 and the second arc-shaped groove 302, and the receiving groove 303 communicates with the first arc-shaped groove 301 and the second arc-shaped groove 302. The first rotating shaft 40 and the second rotating shaft 50 are arranged in the receiving groove 303. By setting it in this way, the first rotating shaft 40 and the second rotating shaft 50 are received in the receiving groove 303, which can avoid the first rotating shaft 40 and the second rotating shaft 50 occupying the space of the foldable electronic device.

[0114] Exemplarily, a first rotation hole and a second rotation hole can be provided on the side wall of the first arc-shaped groove 301 facing away from the second arc-shaped groove 302. Correspondingly, a third rotation hole and a fourth rotation hole are provided on the side wall of the second arc-shaped groove 302 facing away from the first arc-shaped groove 301. One end of the first rotating shaft 40 is inserted into the first rotation hole, the other end of the first rotating shaft 40 is inserted into the third rotation hole, one end of the second rotating shaft 50 is inserted into the second rotation hole, and the other end of the second rotating shaft 50 is inserted into the fourth rotation hole; to realize the connection between the first rotating shaft 40, the second rotating shaft 50 and the fixing member 30.

[0115] In the above implementation, the first synchronous gear 402 and the second synchronous gear 502 meshing with each other are arranged in the accommodating groove 303, the first synchronous gear 402 is connected to the first rotating shaft 40, and the second synchronous gear 502 is connected to the second rotating shaft 50. In this way, when the first connecting member 10 rotates and drives the first rotating shaft 40 to rotate, the second rotating shaft 50 is driven to rotate by the first synchronous gear 402 and the second synchronous gear 502, and then the second connecting member 20 is driven to rotate, so that the first connecting member 10 and the second connecting member 20 rotate, and the first connecting member 10 and the second connecting member 20 rotate in opposite directions, so that the first support member 10 and the second support member can be quickly folded or unfolded.

[0116] Exemplarily, the first synchronous gear 402 and the first rotating shaft 40 may be an integrated structure, and the second synchronous gear 502 and the second rotating shaft 50 may also be an integrated structure, so that the first synchronous gear 402 can drive the first rotating shaft 40 to rotate, and the second synchronous gear 502 can drive the second rotating shaft 50 to rotate. Of course, the first synchronous gear 402 can also be connected to the first rotating shaft 40 by a key connection, and the second synchronous gear 502 can also be connected to the second rotating shaft 50 by a key connection.

[0117] Continue to refer to Figure 1 and Figure 2 In this embodiment, the folding module also includes a push-up spring and a first push-up plate 404, the first push-up plate 404 is arranged between the push-up spring and the first synchronous gear 402 and the second synchronous gear 502; a first push-up ring 403 is sleeved on the first rotating shaft 40, the first push-up ring 403 is located between the first synchronous gear 402 and the first push-up plate 404, and the first push-up ring 403 is connected to the first synchronous gear 402, and a second push-up ring 503 is sleeved on the second rotating shaft 50, the second push-up ring 503 is located between the second synchronous gear 502 and the first push-up plate 404, and the second push-up ring 503 is connected to the second synchronous gear 502; the push-up spring is used to push the first push-up plate 404 against the first push-up ring 403 and the second push-up ring 503, so that the first push-up plate 404 is in contact with the first push-up ring 403 and the second push-up ring 503. When the foldable electronic device is folded or unfolded, the friction between the first abutting plate 404 and the first abutting ring 403 and the second abutting ring 503 prevents the first rotating shaft 40 and the second rotating shaft 50 from rotating, thereby providing a damping force for folding or unfolding to improve the user experience.

[0118] For example, one end of the abutting spring may abut against a side of the first abutting plate 404 away from the first synchronous gear 402 and the second synchronous gear 502 , and the other end of the abutting spring may be connected to the fixing member 30 .

[0119] Please refer to Figure 1 ,Figure 2 , Figure 4 , Figure 5 . In the above implementation, the first abutting ring 403 and the first synchronous gear 402 can be an integral structure. Of course, the first abutting ring 403 and the first synchronous gear 402 can also be a split structure. In the implementation where the first abutting ring 403 and the first synchronous gear 402 are a split structure, a first driving block 4031 can be provided on the first abutting ring 403. Correspondingly, a first driving groove 4021 is provided on the first synchronous gear 402. The first driving block 4031 is clamped in the first driving groove 4021 to drive the first abutting ring 403 to rotate while the first synchronous gear 402 rotates. Among them, the first driving block 4031 can be provided on the outer edge of the first abutting ring 403 and extend towards the first synchronous gear 402. Correspondingly, the first driving groove 4021 is provided between two adjacent teeth on the first synchronous gear 402. Of course, the first driving block 4031 can also be provided on the side surface of the first abutting ring 403 facing the first synchronous gear 402. Correspondingly, the first driving groove 4021 is provided on the spoke of the first synchronous gear 402. With such a setting, the structure is simple and the assembly is convenient. It should be noted that since the first connecting member 10 and the second connecting member 20 only rotate a certain angle during the folding or unfolding of the foldable electronic device, when the first sliding groove 4032 is provided between two adjacent teeth, it will not affect the meshing between the first synchronous gear 402 and the second synchronous gear 502.

[0120] Furthermore, the second abutting ring 503 and the second synchronous gear 502 can be an integral structure. Of course, the second abutting ring 503 and the second synchronous gear 502 can also be a split structure. In the implementation where the second abutting ring 503 and the second synchronous gear 502 are a split structure, a second driving block 5031 can be provided on the second abutting ring 503. Correspondingly, a second driving groove 5021 is provided on the second synchronous gear 502. The second driving block 5031 is clamped in the second driving groove 5021 to drive the second abutting ring 503 to rotate while the second synchronous gear 502 rotates. Among them, the second driving block 5031 can be provided on the outer edge of the second abutting ring 503 and extend towards the second synchronous gear 502. Correspondingly, the second driving groove 5021 is provided between two adjacent teeth on the second synchronous gear 502. Of course, the second driving block 5031 can also be provided on the side surface of the second abutting ring 503 facing the second synchronous gear 502. Correspondingly, the second driving groove 5021 is provided on the spoke of the second synchronous gear 502. It should be noted that since the first connecting member 10 and the second connecting member 20 only rotate a certain angle during the folding or unfolding of the foldable electronic device, when the second sliding groove 5032 is provided between two adjacent teeth, it will not affect the meshing between the first synchronous gear 402 and the second synchronous gear 502.

[0121] In some implementations, the first abutting ring 403 and the first synchronous gear 402 are of a split structure, and the same second abutting ring 503 and the second synchronous gear 502 are also of a split structure, so that after the first abutting ring 403 and the second abutting ring 503 are worn, it is convenient to replace the first abutting ring 403 and the second abutting ring 503, facilitating the maintenance of the folding module.

[0122] In the above implementation, a first hole 4042 and a second hole 4043 are provided on the first abutting plate 404. The first rotating shaft 40 is arranged in the first hole 4042, and the second rotating shaft 50 is arranged in the second hole 4043, thereby realizing the connection between the first abutting plate 404 and the first rotating shaft 40 and the second rotating shaft 50. The structure is simple and the installation is convenient.

[0123] Please refer to Figure 1 、 Figure 2 、 Figures 4 - 7 。 Further, a first sliding groove 4032 and a first sliding block 4041 that are mutually engaged are provided between the first abutting plate 404 and the first abutting ring 403, and a second sliding groove 5032 and a second sliding block 4044 that are mutually engaged are provided between the first abutting plate 404 and the second abutting ring 503. With such a setting, when the folding electronic device is fully unfolded or folded together, the first sliding block 4041 slides in the first sliding groove 4032, and the second sliding block 4044 slides in the second sliding groove 5032, so that the folding electronic device remains in the fully unfolded or folded-together state, improving the user experience; in addition, during the unfolding or folding process, the first sliding block 4041 can slide out of the first sliding groove 4032, and at the same time the second sliding block 4044 slides out of the second sliding groove 5032. At this time, the first abutting plate 404 is driven to compress the abutting spring, further increasing the damping force.

[0124] In this embodiment, both the first sliding block 4041 and the second sliding block 4044 can be multiple, and are both arranged on the first abutting plate 404. The multiple first sliding blocks 4041 are arranged around the first rotating shaft 40, and the multiple second sliding blocks 4044 are arranged around the second rotating shaft 50; correspondingly, multiple first sliding grooves 4032 are arranged on the first abutting ring 403, the multiple first sliding grooves 4032 are arranged around the first rotating shaft 40, multiple second sliding grooves 5032 are arranged on the second abutting ring 503, and the multiple second sliding grooves 5032 are arranged around the second rotating shaft 50; under the action of the abutting spring, the first abutting plate 404 fits with the first abutting ring 403 and the second abutting ring 503, so that each first sliding block 4041 slides into a first sliding groove 4032, and at the same time each second sliding block 4044 slides in a second sliding groove 5032. With such a setting, the damping force during the folding and unfolding process can be further increased, further improving the user experience.

[0125] Exemplarily, when the foldable electronic device is fully unfolded, each first slider 4041 is slidably disposed in a first chute 4032, and each second slider 4044 is slidably disposed in a second chute 5032; when the foldable electronic device is gradually folded, the first connecting member 10 and the second connecting member 20 rotate. At this time, the first slider 4041 gradually slides out of the first chute 4032, and the second slider 4044 gradually slides out of the second chute 5032, and the abutting spring is compressed to provide a damping force; when the first support member and the second support member are about to be folded together, the first slider 4041 gradually slides into the next first chute 4032, and the second slider 4044 gradually slides into the next second chute 5032. The abutting spring drives the first abutting plate 404 to move towards the first abutting ring 403 and the second abutting ring 503, thereby providing a driving force for the rotation of the first support member and the second support member until the first support member and the second support member are folded together.

[0126] In the above implementation manner, the abutting spring includes a first abutting spring 405 sleeved on the first rotating shaft 40 and a second abutting spring 504 sleeved on the second rotating shaft 50. With such a setting, the first abutting spring 405 and the second abutting spring 504 simultaneously abut the first abutting plate 404 to further increase the resistance and driving force during the folding or unfolding of the foldable electronic device, thereby further improving the user experience.

[0127] In this embodiment, a first shaft hole 4022 is provided on the first synchronous gear 402, and the first rotating shaft 40 is inserted into the first shaft hole 4022; similarly, a second shaft hole 5022 is provided on the second synchronous gear 502, and the second rotating shaft 50 is inserted into the second shaft hole 5022; in order to drive the first synchronous gear 402 to rotate when the first rotating shaft 40 rotates and drive the second synchronous gear 502 to rotate when the second rotating shaft 50 rotates, a transmission connection is provided between the first rotating shaft 40 and the first synchronous gear 402, and a transmission connection is provided between the second rotating shaft 50 and the second synchronous gear 502.

[0128] Exemplarily, a first key groove may be provided on the side wall of the first shaft hole 4022, a first driving key is provided on the first rotating shaft 40, and when the first rotating shaft 40 is inserted into the first shaft hole 4022, the first driving key cooperates with the first key groove to achieve the transmission connection between the first rotating shaft 40 and the first synchronous gear 402. Similarly, a second key groove is provided on the side wall of the second shaft hole 5022, a second driving key is provided on the second rotating shaft 50, and when the second rotating shaft 50 is inserted into the second shaft hole 5022, the second driving key cooperates with the second key groove to achieve the transmission connection between the second rotating shaft 50 and the second synchronous gear 502.

[0129] Further, the folding module further includes a first connecting plate 60 located on the side of the first synchronous gear 402 and the second synchronous gear 502 away from the abutting spring. The first connecting plate 60 is provided with a first through hole 601 and a second through hole 602. The first rotating shaft 40 is inserted into the first through hole 601, and the second rotating shaft 50 is inserted into the second through hole 602; the connection between the first rotating shaft 40 and the second rotating shaft 50 can be realized through the first connecting plate 60. There is a first abutting flange 304 between the accommodating groove 303 and the first arc groove 301, and the first connecting plate 60 abuts against the side of the first abutting flange 304 away from the first arc groove 301. The first connecting plate 60 is restricted in the accommodating groove 303 by the first abutting flange 304, with a simple structure and facilitating the disassembly and installation of the first rotating shaft 40 and the second rotating shaft 50.

[0130] Please refer to Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 。In the above implementation manner, the folding module further includes a third synchronous gear 407, a fourth synchronous gear 507 and a second abutting plate 505 that mesh with each other. The third synchronous gear 407 is arranged on the first rotating shaft 40, the fourth synchronous gear 507 is arranged on the second rotating shaft 50, and the second abutting plate 505 is located between the abutting spring and the third synchronous gear 407 and the fourth synchronous gear 507. A third abutting ring 406 is arranged between the third synchronous gear 407 and the second abutting plate 505. The third abutting ring 406 is sleeved on the first rotating shaft 40 and is connected to the third synchronous gear 407; a fourth abutting ring 506 is arranged between the fourth synchronous gear 507 and the second abutting plate 505. The fourth abutting ring 506 is sleeved on the second rotating shaft 50 and is connected to the fourth synchronous gear 507; the abutting spring abuts against the second abutting plate 505 to make the second abutting plate 505 fit with the third abutting ring 406 and the fourth abutting ring 506.

[0131] With such a setting, through the meshing between the third synchronous gear 407 and the fourth synchronous gear 507, the rotation of the first rotating shaft 40 and the second rotating shaft 50 can be further enabled, so that the folding electronic device can be quickly folded and unfolded; in addition, the second abutting plate 505 fits with the third abutting ring 406 and the fourth abutting ring 506, and the frictional force between the second abutting plate 505 and the third abutting ring 406 and the fourth abutting ring 506 can provide a damping force for the unfolding and folding of the folding electronic device to further improve the user experience.

[0132] Further, a third hole 5053 and a fourth hole 5054 are provided on the second abutting top plate 505. The first rotating shaft 40 is disposed in the third hole 5053, and the second rotating shaft 50 is disposed in the fourth hole 5054 to achieve the connection between the second abutting top plate 505 and the first rotating shaft 40 and the second rotating shaft 50. The structure is simple and easy to manufacture.

[0133] There are a third sliding groove 4062 and a third sliding block 5051 that are mutually engaged between the second abutting top plate 505 and the third abutting ring 406. Similarly, there are a fourth sliding groove 5062 and a fourth sliding block 5052 that are mutually engaged between the second abutting top plate 505 and the fourth abutting ring 506. With such an arrangement, when the foldable electronic device is fully unfolded or folded together, the third sliding block 5051 slides in the third sliding groove 4062, and the fourth sliding block 5052 slides in the fourth sliding groove 5062, so that the foldable electronic device remains in a fully unfolded or folded-together state, thereby improving the user experience. In addition, during the unfolding or folding process, the third sliding block 5051 can slide out of the third sliding groove 4062, and at the same time, the fourth sliding block 5052 slides out of the fourth sliding groove 5062. At this time, the second abutting top plate 505 is driven to compress the abutting spring to further increase the damping force.

[0134] In the above implementation manner, both the third sliding block 5051 and the fourth sliding block 5052 are provided on the second abutting top plate 505 and are both multiple. The multiple third sliding blocks 5051 are arranged at intervals around the first rotating shaft 40, and the multiple fourth sliding blocks 5052 are arranged at intervals around the second rotating shaft 50. Correspondingly, both the third sliding groove 4062 and the fourth sliding groove 5062 are multiple. The multiple third sliding grooves 4062 are provided on the third abutting ring 406 and are arranged at intervals around the first rotating shaft 40, and the multiple fourth sliding grooves 5062 are provided on the fourth abutting ring 506 and are arranged at intervals around the second rotating shaft 50. Each third sliding block 5051 slides in one third sliding groove 4062, and each fourth sliding block 5052 slides in one fourth sliding groove 5062. With such an arrangement, the damping force during the folding and unfolding process can be further increased, and the user experience can be further improved.

[0135] Exemplarily, when the foldable electronic device is fully unfolded, each first slider 4041 is slidably disposed in a first chute 4032, and each second slider 4044 is slidably disposed in a second chute 5032; and each third slider 5051 is slidably disposed in a third chute 4062, and each fourth slider 5052 is slidably disposed in a fourth chute 5062, so that the foldable electronic device is maintained in a fully unfolded state. When gradually folding the foldable electronic device, the first connecting member 10 and the second connecting member 20 rotate. At this time, the first slider 4041 gradually slides out of the first chute 4032, and the second slider 4044 gradually slides out of the second chute 5032, and the abutting spring is compressed to provide a damping force; at the same time, the third slider 5051 gradually slides out of the third chute 4062, and the fourth slider 5052 gradually slides out of the fourth chute 5062, and the abutting spring is further compressed to further provide a damping force. When the first support member and the second support member are about to fold together, the first slider 4041 gradually slides into the next first chute 4032, and the second slider 4044 gradually slides into the next second chute 5032. The abutting spring drives the first abutting plate 404 to move towards the first abutting ring 403 and the second abutting ring 503, thereby providing a driving force for the rotation of the first support member and the second support member until the first support member and the second support member are folded together; at the same time, the third slider 5051 gradually slides into the next third chute 4062, and the fourth slider 5052 gradually slides into the next fourth chute 5062. The abutting spring drives the second abutting plate 505 to move towards the third abutting ring 406 and the fourth abutting ring 506, thereby further providing a driving force for the rotation of the first support member and the second support member until the first support member and the second support member are folded together.

[0136] In an implementation manner where the abutting spring includes a first abutting spring 405 sleeved on the first rotating shaft 40 and a second abutting spring 504 sleeved on the second rotating shaft 50, one ends of the first abutting spring 405 and the second abutting spring 504 abut against the first abutting plate 404, and the other ends of the first abutting spring 405 and the second abutting spring 504 abut against the second abutting plate 505.

[0137] In the above implementation manner, the third abutting ring 406 and the third synchronous gear 407 may be an integral structure. Of course, the third abutting ring 406 and the third synchronous gear 407 may also be a split structure. In the implementation manner where the third abutting ring 406 and the third synchronous gear 407 are a split structure, a third driving block 4061 may be provided on the third abutting ring 406. Correspondingly, a third driving groove 4071 is provided on the third synchronous gear 407. The third driving block 4061 is clamped in the third driving groove 4071 to drive the third abutting ring 406 to rotate while the third synchronous gear 407 rotates. Among them, the third driving block 4061 may be provided on the outer edge of the third abutting ring 406 and extend towards the third synchronous gear 407. Correspondingly, the third driving groove 4071 is provided between two adjacent teeth on the third synchronous gear 407. Of course, the third driving block 4061 may also be provided on the side surface of the third abutting ring 406 facing the third synchronous gear 407. Correspondingly, the third driving groove 4071 is provided on the spoke of the third synchronous gear 407. It should be noted that since the first connecting member 10 and the second connecting member 20 only rotate a certain angle during the folding or unfolding process of the foldable electronic device, the third sliding groove 4062 is provided between two adjacent teeth and does not affect the meshing between the third synchronous gear 407 and the fourth synchronous gear 507.

[0138] Furthermore, the fourth abutting ring 506 and the fourth synchronous gear 507 may be an integral structure. Of course, the fourth abutting ring 506 and the fourth synchronous gear 507 may also be a split structure. In the implementation manner where the fourth abutting ring 506 and the fourth synchronous gear 507 are a split structure, a fourth driving block 5061 may be provided on the fourth abutting ring 506. Correspondingly, a fourth driving groove 5071 is provided on the fourth synchronous gear 507. The fourth driving block 5061 is clamped in the fourth driving groove 5071 to drive the fourth abutting ring 506 to rotate while the fourth synchronous gear 507 rotates. Among them, the fourth driving block 5061 may be provided on the outer edge of the fourth abutting ring 506 and extend towards the fourth synchronous gear 507. Correspondingly, the fourth driving groove 5071 is provided between two adjacent teeth on the fourth synchronous gear 507. Of course, the fourth driving block 5061 may also be provided on the side surface of the fourth abutting ring 506 facing the fourth synchronous gear 507. Correspondingly, the fourth driving groove 5071 is provided on the spoke of the fourth synchronous gear 507. It should be noted that since the first connecting member 10 and the second connecting member 20 only rotate a certain angle during the folding or unfolding process of the foldable electronic device, the fourth sliding groove 5062 is provided between two adjacent teeth and does not affect the meshing between the third synchronous gear 407 and the fourth synchronous gear 507.

[0139] In some implementations, the third top ring 406 and the third synchronization gear 407 are split structures, and the fourth top ring 506 and the fourth synchronization gear 507 are also split structures, so that the third top ring 406 and the fourth top ring 506 can be easily replaced after they are worn, so as to facilitate the maintenance of the folding module.

[0140] In this embodiment, a third shaft hole 4072 is provided on the third synchronous gear 407, and the first rotating shaft 40 is penetrated in the third shaft hole 4072; similarly, a fourth shaft hole 5072 is provided on the fourth synchronous gear 507, and the second rotating shaft 50 is penetrated in the fourth shaft hole 5072; in order to drive the third synchronous gear 407 to rotate when the first rotating shaft 40 rotates, and drive the fourth synchronous gear 507 to rotate when the second rotating shaft 50 rotates, the first rotating shaft 40 and the third synchronous gear 407 are connected by transmission, and the second rotating shaft 50 and the fourth synchronous gear 507 are connected by transmission.

[0141] For example, a third keyway may be provided on the side wall of the third shaft hole 4072, a third driving key may be provided on the first rotating shaft 40, and when the first rotating shaft 40 is inserted into the third shaft hole 4072, the third driving key cooperates with the third keyway to achieve a transmission connection between the first rotating shaft 40 and the third synchronous gear 407.
