[0029] The following is combined Figures 1 to 14 This application describes a hinge and an electronic device according to embodiments thereof.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of this application, a hinge 100 is provided, comprising: a limiting seat 110; a rotating member 120 rotatably connected to the limiting seat 110; a limiting member 130 located between the rotating member 120 and the limiting seat 110, the limiting member 130 being disposed on one of the rotating member 120 and the limiting seat 110; and a limiting portion 140 located between the rotating member 120 and the limiting seat 110, the limiting portion 140 being disposed on one of the rotating member 120 and the limiting seat 110. The other of the rotating member 120 and the limiting seat 110; the elastic part 150, used to drive the limiting member 130 to approach the limiting seat 110 with the limiting part 140 or to drive the limiting member 130 to approach the rotating member 120 with the limiting part 140; when the limiting member 130 is in the first position, the limiting member 130 blocks the limiting part 140 and the rotating member 120 stops; when the limiting member 130 is in the second position, the limiting member 130 avoids the limiting part 140 and the rotating member 120 rotates.

[0031] The hinge 100 is mounted on the electronic device 200 and rotates with the movement of the housing 210 structure on the electronic device 200. Specifically, the limiting seat 110 is fixed on the housing 210 and is used to support and position the rotating member 120. The rotating member 120 is connected to the limiting seat 110 and can rotate relative to the limiting seat 110. Part of the housing 210 of the electronic device 200 can rotate relative to the limiting seat 110 with the rotating member 120, thereby adjusting the shape of the electronic device 200 and the shape of the screen by means of this action.

[0032] In related technologies, the two folding structures of the flexible screen 220 mobile phone are hinged by the hinge 100. As the folding angle of the screen increases, the restoring torque exerted by the screen on the hinge 100 becomes greater, causing the hinge 100 to rotate on its own under the pull of the screen. As a result, the flexible screen 220 mobile phone has a problem with difficulty in hovering and a small hovering angle, which damages the user experience.

[0033] In this regard, the electronic device 200 proposed in this application is further provided with a limiting member 130 and a limiting part 140. The limiting member 130 and the limiting part 140 are disposed between the rotating member 120 and the limiting seat 110, and the limiting member 130 and the limiting part 140 are respectively disposed on the limiting seat 110 and the rotating member 120. The limiting member 130 can be disposed on the rotating member 120 and the limiting part 140 can be disposed in the corresponding area of ​​the limiting seat 110, or the limiting part 140 can be disposed on the rotating member 120 and the limiting member 130 can be disposed on the limiting seat 110.

[0034] The hinge 100 also includes an elastic portion 150. One end of the elastic portion 150 is connected to the limiting member 130, and the other end is connected to the limiting seat 110 or the rotating member 120. When the elastic portion 150 is connected to both the limiting seat 110 and the limiting member 130, the elastic portion 150 drives the limiting member 130 closer to the rotating member 120. Correspondingly, when the elastic portion 150 is connected to both the rotating member 120 and the limiting member 130, the elastic portion 150 drives the limiting member 130 closer to the limiting seat 110. Therefore, by providing the elastic portion 150, the limiting member 130 can float relative to the limiting seat 110 or the rotating member 120 to adjust its position.

[0035] Specifically, the limiting member 130 includes a first position and a second position. The first position corresponds to the outward convex state of the limiting member 130, and the second position corresponds to the inward retraction state of the limiting member 130. Taking the limiting part 140 as being provided on the rotating member 120 and the limiting member 130 as being provided on the limiting seat 110 as an example, when the rotating member 120 is stationary, the limiting member 130 is in the first position relatively close to the rotating member 120 and is located on the rotation trajectory of the limiting part 140. In this case, the current posture is maintained by the elastic part 150. At this time, the limiting member 130 and the limiting part 140 abut together, thereby providing the rotating member 120 with a frictional torque that can resist the restoring torque of the flexible screen 220 through the frictional force of the interlocking surfaces between the limiting member 130 and the limiting part 140. The frictional torque is greater than the restoring torque, so that the flexible screen 220 can be stably suspended in the current state without moving. Correspondingly, when the user needs to adjust the state of the flexible screen 220, a pushing or pulling force is applied to the rotating member 120, making the sum of the pushing / pulling torque and the restoring torque greater than the frictional torque. At this time, the limiting member 130 is pushed from the first position to the second position by the limiting part 140. In the second position, the limiting member 130 avoids the movement trajectory of the limiting part 140, thereby adjusting the shape of the housing 210 and the flexible screen 220 through the rotation of the rotating member 120. The principle of the scheme where the limiting member 130 is set on the rotating member 120 and the limiting part 140 is set on the limiting seat 110 is the same as described above, and will not be repeated here to avoid repetition.

[0036] Therefore, this application, by providing mutually cooperating limiting members 130 and 140 between the rotating member 120 and the limiting seat 110, allows the rotating member 120 and the limiting seat 110 to resist the restoring torque of the flexible screen 220 itself through the frictional torque between the limiting members 130 and 140, thereby achieving the locking of the folding body. This allows the folding body and the associated flexible screen 220 to be stably suspended at multiple different angles, solving the technical problems in related technologies where the hinge 100 structure cannot effectively resist the restoring torque of the flexible screen 220, making it difficult to suspend the flexible screen 220 and limiting the suspension angle. This further optimizes the structure of the electronic device 200, improves the stability and reliability of the folding structure of the electronic device 200, and enhances the user experience.

[0037] Specifically, when there is only one limiting member 130, the limiting member 130 is set on the rotational trajectory of the limiting part 140 during its unfolding action, so as to prevent the hinge 100 from extending outward on its own due to the restoring torque of the flexible screen 220.

[0038] When there are multiple limiting members 130, the multiple limiting members 130 are distributed at intervals on the rotation trajectory of the limiting portion 140. A limiting gap 138 is formed between two adjacent limiting members 130 in the circumferential direction to accommodate the limiting portion 140. The limiting portion 140 is located within the limiting gap 138, and the shape of the limiting portion 140 is adapted to the shape of the limiting gap 138. Furthermore, the number of limiting members 130 is positively correlated with the number of hovering angles designed for the flexible screen 220; increasing the number of limiting members 130 can increase the number of hovering angles of the flexible screen 220.

[0039] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the limiting member 130 is disposed on the limiting seat 110, and the limiting part 140 is disposed on the rotating member 120; the elastic part 150 includes: a first elastic member 152, the first end of the first elastic member 152 is connected to the limiting seat 110, the second end of the first elastic member 152 is connected to the limiting member 130, and the first elastic member 152 is used to push the limiting member 130 in the direction of the rotating member 120.

[0040] In this embodiment, the elastic part 150 includes a first elastic element 152, which is disposed between the limiting seat 110 and the limiting member 130. The first end of the first elastic element 152 is connected to the limiting seat 110, and the second end of the first elastic element 152 is connected to the limiting member 130. The first elastic element 152 can push the limiting member 130 to a first position away from the limiting seat 110, so that the limiting member 130 can be stopped at the first position in the default state, so as to convert the thrust of the first elastic element 152 into a frictional torque that overcomes the restoring torque of the flexible screen 220, and ensure that the flexible screen 220 can be suspended at a specified angle under the action of the limiting part 140 and the limiting member 130.

[0041] The first elastic element 152 of the matching limiting element 130 is provided so that the floating limiting element 130 can be formed on the limiting seat 110. The rotating element 120 needs to push the limiting element 130 to float closer to the limiting seat 110 with the assistance of external force in order to complete the rotation action.

[0042] Therefore, by setting the first elastic element 152, on the one hand, a self-locking force can be provided for the limiting element 130 and the limiting part 140, ensuring that the flexible screen 220 can be stably suspended at a predetermined angle under the action of this self-locking force. On the other hand, the first elastic element 152 can provide a reset force for the limiting element 130, so that the limiting element 130 automatically returns to the first position after being forced to make an avoidance action, so as to facilitate the execution of subsequent locking functions. Thus, the technical effect of optimizing the locking reliability and effectiveness of the limiting element 130 is achieved.

[0043] Specifically, the first elastic element 152 can be selected from structures such as a spring sheet, a compression spring, or a rubber plug. This embodiment does not impose a rigid limitation on the specific structural form of the elastic element, as long as it can meet the locking and rebound requirements.

[0044] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the limiting part 140 is a limiting protrusion provided on the rotating member 120; the limiting seat 110 has a mounting groove 112, the opening of the mounting groove 112 faces the rotating member 120, the first elastic member 152 is provided in the mounting groove 112, and the limiting member 130 can slide along the mounting groove 112.

[0045] In this embodiment, the limiting portion 140 is formed on the rotating member 120 and protrudes from the outer surface of the rotating member 120 to form an outwardly convex structure. Correspondingly, the limiting seat 110 is provided with a mounting groove 112, the opening of the mounting groove 112 faces the rotating member 120, the first elastic member 152 is embedded in the mounting groove 112, and the shape of the mounting groove 112 is adapted to the shape of the limiting member 130, so that the limiting member 130 can be positioned in the depth direction of the mounting groove 112 (e.g., ...). Figure 2Slide on (as indicated by arrow c). Specifically, when making an avoidance action, the limiting member 130 can retract to the second position within the mounting groove 112. After the avoidance is completed, the limiting member 130 extends at least partially out of the mounting groove 112 under the push of the first elastic member 152, so as to stop in the first position, which facilitates the subsequent blocking of the limiting part 140.

[0046] The number and distribution of the mounting slots 112 are consistent with the number and distribution of the limiting members 130, that is, the mounting slots 112 and the limiting members 130 are set in a one-to-one correspondence.

[0047] By setting the mounting groove 112, the limiting member 130 can complete the avoidance action inside the limiting seat 110. Compared with the technical solution where the limiting member 130 avoids outside the limiting seat 110, this embodiment makes reasonable use of the space inside the limiting seat 110, which is conducive to shortening the distance between the limiting seat 110 and the rotating member 120, thereby improving the structural compactness of the hinge 100, reducing the size of the hinge 100, and reducing the difficulty of arranging the hinge 100 inside the electronic device 200.

[0048] Meanwhile, the mounting groove 112 can also guide the limiting member 130, preventing the limiting member 130 from deviating from the predetermined avoidance trajectory during movement, thereby achieving the technical effect of improving the movement accuracy of the limiting member 130 and improving the reliability of the hinge 100.

[0049] Specifically, such as Figure 1 and Figure 12 As shown, in one alternative embodiment, a compression spring is selected as the elastic element. The compression spring is placed in the mounting groove 112, and the extension direction of the compression spring is consistent with the depth direction of the mounting groove 112. The first end of the compression spring abuts against the bottom surface of the mounting groove 112, and the second end of the compression spring is connected to the limiting member 130. When the limiting member 130 is pushed back into the mounting groove 112 by an external force, the length of the compression spring is shortened, and the compression spring accumulates elastic potential energy. After the limiting member 130 and the limiting part 140 are separated, the compression spring releases the elastic potential energy to push the limiting member 130 out of the mounting groove 112 again.

[0050] The compression spring has excellent compressive strength, which can effectively maintain the locking effect of the limiting component 130 on the limiting part 140 for a long time, thereby improving the reliability of the limiting component 130 and reducing its failure rate. At the same time, the compression spring is a standard component that can be purchased, which helps to reduce production costs and thus enhance the product's long-term competitiveness.

[0051] Specifically, such as Figure 1 and Figure 12 As shown, in one alternative embodiment, multiple compression springs are arranged side by side in each mounting slot 112.

[0052] In this embodiment, each mounting groove 112 is provided with multiple compression springs, which are arranged side by side in a direction perpendicular to the depth of the mounting groove 112. The number of compression springs is related to the structural parameters of the compression springs themselves and the restoring torque of the flexible screen 220 at the corresponding angle. Specifically, the frictional torque between the limiting member 130 and the limiting part 140 can be enhanced by increasing the number of compression springs, so that the folding body and the flexible screen 220 can be suspended at a larger folding angle.

[0053] It is evident that increasing the number of compression springs helps to improve the locking effect of the limiting member 130 on the limiting part 140, thereby improving the hovering stability of the flexible screen 220. Moreover, compared to setting a single large compression spring, setting multiple small compression springs side by side can make reasonable use of the limited space in the mounting groove 112, thereby meeting the locking and rebound requirements without increasing the size of the mounting groove 112, thus providing convenient conditions for the miniaturization design of the electronic device 200.

[0054] According to some embodiments of this application, such as Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, the hinge 100 also includes: a positioning post 132, which is disposed on the limiting member 130. The positioning post 132 is located on the side of the limiting member 130 away from the rotating member 120, and the first elastic member 152 is sleeved on the positioning post 132.

[0055] In this embodiment, the limiting member 130 is provided with a positioning post 132 on the side opposite to the rotating member 120. The first elastic member 152 is sleeved on the positioning post 132 to ensure that the extension and retraction direction of the first elastic member 152 is consistent with the depth direction of the mounting groove 112, so as to avoid the first elastic member 152 from being skewed or misaligned, thereby improving the action accuracy of the limiting member 130 and improving the structural stability and reliability of the hinge 100.

[0056] According to some embodiments of this application, such as Figure 1 , Figure 10 and Figure 11 As shown, the outer surface of the limiting member 130 is arched, and / or the outer surface of the limiting part 140 is arched.

[0057] In this embodiment, the outer surface of the limiting member 130 facing the rotating member 120 is arched, and / or the outer surface of the limiting portion 140 protruding from the rotating member 120 is arched. By constructing an arched outer surface on at least one of the limiting member 130 and the limiting portion 140, the smoothness of the arched surface reduces the possibility of the limiting member 130 and the limiting portion 140 getting stuck, preventing the rotating member 120 from rotating, thus reducing the failure rate of the hinge 100. On the other hand, the smoothness of the arched surface also improves the smoothness of the movement of the limiting member 130, thereby reducing the impact of the limiting member 130 on the limiting portion 140 and the limiting seat 110, and thus improving the structural stability of the hinge 100.

[0058] According to some embodiments of this application, such as Figure 1 , Figure 10 and Figure 11 As shown, the hinge 100 includes a first limiting member 1302 and a second limiting member 1304, which are spaced apart on the rotation trajectory of the limiting part 140; the first limiting member 1302 and the second limiting member 1304 have different thicknesses in the rotation axis direction of the rotating member 120.

[0059] In this embodiment, the rotating member 120 has an unfolded position and a closed position relative to the limiting seat 110. In the unfolded position, the flexible screen 220 connected to the rotating member 120 is fully unfolded and integrated into a complete flat screen. In the closed position, the flexible screens 220 are stacked together. Taking a mobile phone with a flexible screen 220 as an example, in the unfolded position, the two sections of the flexible screen 220 are flush, and the included angle between the two sections of the flexible screen 220 is 180°, that is, the folding angle is 0°. During the process of bending the rotating member 120 from the unfolded position to the closed position, the included angle between the two sections of the flexible screen 220 gradually decreases from 180°, and the folding angle gradually increases until the two sections of the flexible screen 220 are stacked together, that is, the included angle is 0° and the folding angle is 180°.

[0060] During the process of rotating member 120 rotating from the unfolded position to the closed position, the rotation trajectory of limiting part 140 relative to limiting seat 110 is the target trajectory, such as... Figure 7 As shown, the rotating component 120 is provided with two limiting parts 140, one on the left and one on the right. The target trajectory of the left limiting part 140 is shown as arrow a, and the target trajectory of the right limiting part 140 is shown as arrow b. It can be seen that during the process of switching the folding body to the closed position, the limiting part 140 needs to cross the first limiting part 1302 and the second limiting part 1304 in sequence. Specifically, there can be multiple second limiting parts 1304.

[0061] Based on this, the first limiting member 1302 and the second limiting member 1304 have different thicknesses. During rotation, the limiting part 140 needs to pass over the limiting member 130. Increasing the height of the limiting member 130 increases the stroke required for the limiting part 140 to push the limiting member 130 to avoid it, thus increasing the frictional torque provided by the limiting member 130 to the limiting part 140. Conversely, reducing the thickness of the limiting member 130 decreases the frictional torque provided by the limiting member 130 to the limiting part 140. By constructing the first limiting member 1302 and the second limiting member 1304 with different heights, a refined design of the frictional torque provided by the limiting member 130 can be achieved, ensuring that each limiting member 130 can meet the hovering requirements at the corresponding angle.

[0062] Specifically, on the target trajectory, the thickness of the second limiting part 140 is greater than the thickness of the first limiting part 140, and the thickness of the plurality of second limiting members 1304 gradually increases on the target trajectory. This causes the frictional torque provided by the plurality of limiting members 130 that the limiting part 140 successively crosses to gradually increase, so that the limiting members 130 can match the screen recovery torque that increases synchronously with the folding angle.

[0063] According to some embodiments of this application, such as Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the limiting member 130 includes a connecting portion 134 and a boss 136. The connecting portion 134 and the boss 136 are stacked in the rotation axis direction. The connecting portion 134 is close to the limiting seat 110, and the boss 136 is close to the rotating member 120. The connecting portion 134 is connected to the limiting seat 110 through a first elastic member 152, and the boss 136 is detachably connected to the connecting portion 134. The first limiting member 1302 includes a first boss 136, and the second limiting member 1304 includes a second boss 136. In the rotation axis direction of the rotating member 120, the first boss 136 and the second boss 136 have different thicknesses.

[0064] In this embodiment, the structure of the limiting member 130 is described. Specifically, the limiting member 130 includes a connecting portion 134 and a boss 136. The connecting portion 134 is fitted into the mounting groove 112 and slides along the extending direction of the mounting groove 112. The mounting groove 112 can limit the connecting portion 134 to prevent it from being pushed out of the mounting groove 112 by the compression spring. The boss 136 is disposed on the surface of the connecting portion 134 facing the rotating member 120. The first elastic member 152 is connected to the surface of the connecting portion 134 away from the rotating member 120. The size of the boss 136 is adapted to the size of the opening of the mounting groove 112, and the boss 136 can penetrate through the opening of the mounting groove 112. When the limiting member 130 is in the first position, the connecting part 134 is engaged inside the opening of the mounting groove 112, and the boss 136 protrudes outward from the opening of the mounting groove 112 to block the limiting part 140 on its movement trajectory, thereby achieving a locking function. When the user folds the main body, the boss 136 is pushed into the opening of the mounting groove 112 by the limiting part 140. At this time, the rotating member 120 can rotate relative to the limiting seat 110, thereby adjusting the state of the flexible screen 220. Finally, after the limiting part 140 slides past the opening of the mounting groove 112, the limiting part 140 extends out of the mounting groove 112 again under the action of the compression spring.

[0065] Therefore, this structure can meet the vertical floating motion requirements of the limiting component 130, and the movement accuracy of the limiting component 130 can be improved through structural coordination with the limiting device. This achieves the technical effects of optimizing the structure of the limiting component 130, reducing the failure rate of the electronic device 200, and improving the user experience of the flexible screen 220.

[0066] Specifically, the connecting portion 134 of the first limiting member 1302 and the second limiting member 1304 has the same size. The first limiting member 1302 is provided with a first boss 136, and the second limiting member 1304 is provided with a second boss 136. The thicknesses of the first boss 136 and the second boss 136 are different, thereby constructing the first limiting member 1302 and the second limiting member 1304 that provide different frictional torques.

[0067] Specifically, the boss 136 and the connector are detachably connected so that the user can adjust the frictional torque provided by the corresponding limiter 130 by replacing the boss 136 with one of different sizes.

[0068] According to some embodiments of this application, such as Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the limiting member 130 includes: a first limiting member 1302; a second limiting member 1304, the first limiting member 1302 and the second limiting member 1304 being spaced apart on the rotation trajectory of the limiting part 140; the first elastic member 152 includes: a first spring 1522 connected to the first limiting member 1302; a second spring 1524 connected to the second limiting member 1304, the first spring 1522 and the second spring 1524 having different stiffnesses.

[0069] In this embodiment, the rotating member 120 has an unfolded position and a closed position relative to the limiting seat 110. In the unfolded position, the flexible screen 220 connected to the rotating member 120 is fully unfolded and integrated into a complete flat screen. In the closed position, the flexible screens 220 are stacked together. Taking a mobile phone with a flexible screen 220 as an example, in the unfolded position, the two sections of the flexible screen 220 are flush, and the included angle between the two sections of the flexible screen 220 is 180°, that is, the folding angle is 0°. During the process of bending the rotating member 120 from the unfolded position to the closed position, the included angle between the two sections of the flexible screen 220 gradually decreases from 180°, and the folding angle gradually increases until the two sections of the flexible screen 220 are stacked together, that is, the included angle is 0° and the folding angle is 180°.

[0070] During the process of rotating member 120 rotating from the unfolded position to the closed position, the rotation trajectory of limiting part 140 relative to limiting seat 110 is the target trajectory, such as... Figure 7 As shown, the rotating component 120 is provided with two limiting parts 140, one on the left and one on the right. The target trajectory of the left limiting part 140 is shown as arrow a, and the target trajectory of the right limiting part 140 is shown as arrow b. It can be seen that during the process of switching the folding body to the closed position, the limiting part 140 needs to cross the first limiting part 1302 and the second limiting part 1304 in sequence. Specifically, there can be multiple second limiting parts 1304.

[0071] Based on this, the first elastic element 152 includes a first spring 1522 and a second spring 1524. The first spring 1522 connects the first limiting element 1302 and the limiting seat 110, and the second spring 1524 connects the second limiting element 1304 and the limiting seat 110. The first spring 1522 and the second spring 1524 have different stiffnesses.

[0072] During rotation, the limiting part 140 needs to cross the limiting member 130. The magnitude of the force exerted by the limiting member 130 on the limiting part 140 is directly related to the stiffness of the spring. The higher the stiffness of the spring, the greater the pushing force exerted by the limiting member 130 on the limiting part 140, and the greater the corresponding frictional torque. Conversely, the lower the stiffness, the smaller the frictional torque. By constructing a first spring 1522 and a second spring 1524 with different stiffnesses, it is possible to achieve a precise design of the frictional torque provided by the limiting member 130, ensuring that each limiting member 130 can meet the hovering requirements at the corresponding angle.

[0073] Specifically, on the target trajectory, the stiffness of the second spring 1524 is greater than that of the first spring 1522, and the stiffness of the multiple second springs 1524 gradually increases on the target trajectory. This causes the frictional torque provided by the multiple limiting members 130 that the limiting part 140 successively crosses to gradually increase, so that the limiting member 130 can match the screen recovery torque that increases synchronously with the folding angle.

[0074] Specifically, to achieve this gradual change in frictional torque, the boss 136 of the limiting member 130 on the target trajectory is gradually increased in height, and / or the stiffness of the spring connected to the limiting member 130 on the target trajectory is gradually increased. For example... Figure 13 As shown, the limiting part 140 needs to pass over the first limiting member 1302 and multiple second limiting members 1304 in sequence. The height of the first boss 136 on the first limiting member 1302 is H1, and the stiffness of the first spring 1522 connected to the first limiting member 1302 is K1. The maximum frictional torque that can be generated by the combination of the two is M1. The height of the second boss 136 on the second limiting member 1304 is H2, where H2 is greater than H1. The stiffness of the second spring 1524 connected to the second limiting member 1304 is K2, where K2 is greater than K1. Thus, a limiting member 130 that can generate a maximum frictional torque of M2 is formed, where M2 is greater than M1. By analogy, an array of limiting members 130 with gradually increasing maximum frictional torque can be formed.

[0075] Combination Figure 14 As shown, the restoring torque of the flexible screen 220 gradually increases with the increase of the folding angle of the flexible screen 220. By ensuring that the maximum torque provided by each limiting component 130 is greater than the restoring torque of the flexible screen 220 in the corresponding rotation angle range, the restoring torque curve of the flexible screen 220 is covered inside the torque trapezoidal diagram of the limiting component 130, thereby achieving torque overtaking of the flexible screen 220 at all angles. It can also meet the personalized design requirements of the hovering torque at various angles, thus completely solving the technical defects of poor hovering reliability and small hovering angle of the flexible screen 220.

[0076] According to some embodiments of this application, such as Figure 7 As shown, the hinge 100 includes a plurality of limiting members 130, which are distributed at intervals around the pivot of the rotating member 120; wherein, a limiting gap 138 is formed between two adjacent limiting members 130, and the shape of the limiting gap 138 is adapted to the shape of the limiting part 140; when the limiting member 130 is in the first position, the limiting part 140 is engaged in the limiting gap 138.

[0077] In this embodiment, the hinge 100 includes a plurality of limiting members 130, which are spaced apart on the rotation trajectory of the limiting portion 140. A limiting gap 138 for accommodating the limiting portion 140 is formed between two adjacent limiting members 130 in the circumferential direction. When the limiting member 130 is in the first position, the limiting portion 140 is located within the limiting gap 138, and the shape of the limiting portion 140 is adapted to the shape of the limiting gap 138 to ensure that the limiting portion 140 can be snapped between the two limiting members 130.

[0078] Specifically, such as Figure 7 As shown, the width of the limiting gap 138 gradually changes in the radial direction away from the axis of rotation of the rotating member 120.

[0079] By setting a limiting gap 138 with a gradually changing width, the limiting gap 138 can provide radial limiting for the limiting part 140, thereby ensuring that the rotating part 120 can be accurately positioned on the limiting seat 110 and preventing the rotating part 120 from radially shifting relative to the limiting seat 110 during rotation.

[0080] Specifically, there are multiple limiting parts 140, which surround the rotating shaft of the rotating member 120 and are distributed at intervals.

[0081] In this embodiment, there are multiple limiting parts 140 provided in conjunction with the limiting member 130. The multiple limiting parts 140 are also distributed at intervals on a circle with the rotation axis of the rotating member 120 as the axis. In order to ensure that the limiting parts 140 can match the limiting member 130, the number of limiting parts 140 must be less than or equal to the number of limiting members 130, so that at most one limiting part 140 is arranged between two adjacent limiting members 130.

[0082] Increasing the number of limiting portions 140 increases the total frictional torque provided by the limiting member 130 to the rotating member 120. In other words, the more limiting portions 140 there are, the greater the total frictional torque provided. Thus, without changing the inherent properties of the limiting member 130, adjusting the number of limiting portions 140 enhances the hovering reliability and stability of the flexible screen 220. For example, Figure 7 The rotating member 120 is provided with two limiting parts 140, and the included angle between the two limiting parts 140 is 180°. In the hovering state, the two sets of limiting parts 130 lock the rotating member 120 together to increase the frictional torque provided by the limiting parts 130 on the rotating member 120.

[0083] According to some embodiments of this application, such as Figure 8 , Figure 9 , Figure 10 and Figure 11As shown, the hinge 100 further includes: a hinge shaft 160, which passes through the rotating member 120 and is connected to the limiting seat 110; a limiting post 162, which is located on the side of the rotating member 120 away from the limiting seat 110; and a swing arm 164, which is connected to the hinge shaft 160. The swing arm 164 has a slot, and the limiting post 162 is inserted into the slot, so that the rotating member 120 rotates with the swing arm 164 through the slot and the limiting post 162.

[0084] In this embodiment, the hinge 100 further includes a swing arm 164, which is used to connect to the housing 210 of the electronic device 200 and rotates synchronously with the housing 210. The swing arm 164 has a slot, and the first end of the rotating member 120 is hinged to the limiting seat 110 via a hinge shaft 160. The second end of the rotating member 120 has a positioning post 132, which is inserted into the slot. When the user pries the housing 210, the swing arm 164, through the cooperation of the slot and the positioning post 132, drives the rotating member 120 to rotate relative to the limiting seat 110, thereby adjusting the folding angle of the flexible screen 220 through the rotation. Correspondingly, after the user removes the external force, the limiting member 130 on the limiting seat 110 and the limiting part 140 on the rotating member 120 cooperate to lock the rotating member 120, causing the rotating member 120 to hover at the current angle, thus keeping the flexible screen 220 in a hovered state.

[0085] By providing a swing arm 164 between the rotating component 120 and the housing 210, the stress concentration problem can be alleviated by increasing the connection contact area, thereby improving the structural stability of the hinge 100 and reducing its failure rate. Simultaneously, providing the rotating component 120 as an independent structure for arranging the limiting part 140 or the limiting part 130 facilitates the maintenance of the limiting part 130 or the limiting part 140. For example, if the limiting part 130 or the limiting part 140 suffers excessive wear due to prolonged use, it can be maintained or replaced by disassembling the rotating component 120 separately. This achieves the technical effect of optimizing the hinge 100 structure and reducing the maintenance difficulty of the electronic device 200.

[0086] According to some embodiments of this application, such as Figure 5 and Figure 6 As shown, the hinge 100 also includes a friction block 180, which abuts against the side of the rotating member 120 away from the limiting seat 110, for providing sliding friction to the rotating member 120.

[0087] In this embodiment, the hinge 100 is further provided with a friction block 180. The friction block 180 is press-fitted onto the side of the rotating member 120 away from the limiting seat 110 via the hinge shaft 160. The surface of the friction block 180 is relatively rough. The friction block 180 pressed onto the rotating member 120 can provide friction torque to the rotating member 120, thereby enhancing the hovering reliability and stability of the flexible screen 220 in conjunction with the limiting member 130 and the limiting part 140. At the same time, the setting of the friction block 180 can form a double insurance. Even if some of the limiting members 130 fail, the friction torque provided by the friction block 180 can still meet the hovering requirements of the flexible screen 220 to a certain extent, thereby achieving the technical effect of improving the structural reliability of the hinge 100 and extending the service life of the hinge 100.

[0088] According to some embodiments of this application, such as Figure 5 and Figure 6 As shown, the limiting member 130 is provided on the limiting seat 110, and the limiting part 140 is provided on the rotating member 120; the elastic part 150 includes a second elastic member 154, which is connected to the limiting seat 110 and is located on the side of the limiting seat 110 away from the rotating member 120, for pushing the limiting seat 110 closer to the rotating member 120.

[0089] In this embodiment, the limiting member 130 is disposed on the limiting seat 110, and the limiting part 140 is formed on the rotating member 120. Furthermore, the hinge 100 also includes a plate 170, and the elastic part 150 includes a second elastic member 154. One end of the second elastic member 154 abuts against the plate 170, and the other end abuts against the limiting seat 110, so that the elastic force of the second elastic member 154 pushes the limiting seat 110 closer to the rotating member 120. The second elastic member 154 is always in a compressed state to press the limiting seat 110 tightly against the rotating member 120, ensuring that the limiting seat 110, the rotating member 120, and the friction block 180 are in close contact. This ensures that the limiting member 130, the limiting part 140, and the friction block 180 can stably provide frictional torque, preventing the locking function from failing due to loosening. This achieves the technical effect of optimizing the hinge 100 structure, improving the reliability and stability of the folding screen's hovering function, and reducing the hinge 100 failure rate.

[0090] Specifically, the hinge shaft 160 passes through the friction block 180, the rotating component 120, and the limiting seat 110 in sequence, and connects with the plate 170 to complete the assembly of the rotating component 120 and the limiting seat 110. During disassembly, the limiting seat 110 is disassembled synchronously with the rotating component 120.

[0091] According to some embodiments of this application, such as Figure 4 As shown, an electronic device 200 is proposed, which includes: a housing 210; a hinge 100 as in any of the above embodiments; and a limiting seat 110 disposed on the housing 210.

[0092] In this embodiment, an electronic device 200 is provided, which is provided with the hinge 100 of any of the above embodiments, and the limiting seat 110 is mounted on the housing 210. Therefore, the electronic device 200 has the advantages of the hinge 100 of any of the above embodiments and can achieve the technical effects that the hinge 100 of any of the above embodiments can achieve. To avoid repetition, it will not be described again here.

[0093] Specifically, the housing 210 includes: a first housing 212 connected to the first end of the limiting seat 110; and a second housing 214 connected to the second end of the limiting seat 110. The rotating member 120 includes: a first rotating member 120 connected to the first housing 212 via a swing arm 164; and a second rotating member 120 connected to the second housing 214 via a swing arm 164.

[0094] In this embodiment, the flexible screen 220 proposed in this application is divided into two sections. The two flexible screens 220 at both ends are respectively connected to the first housing 212 and the second housing 214. Based on this, a dual-axis hinge scheme is adopted, that is, the first housing 212 is rotatably connected to the limiting seat 110 through the first rotating member 120 and the swing arm 164, and the second housing 214 is rotatably connected to the limiting seat 110 through the second rotating member 120 and the swing arm 164, so that the two sections of the flexible screen 220 can rotate independently relative to the limiting seat 110.

[0095] By adopting the above-mentioned dual-axis hinge scheme, the rotational stroke of the housing 210 can be shortened. The flexible screen 220 can be closed or unfolded by rotating the two housings 210 by 90° respectively, thereby improving the stability and reliability of the electronic device 200 by shortening the movement stroke. At the same time, two sets of limiting members 130 and limiting parts 140 are respectively provided between the two rotating parts 120 and the limiting seat 110. The two sets of limiting members 130 and limiting parts 140 jointly resist the restoring torque of the flexible screen 220, thereby reducing the frictional torque required by the limiting parts 140 and the limiting members 130. This reduces the size of the limiting parts 140 and the compression spring, thus providing convenient conditions for the miniaturization and lightweight design of the electronic device 200.

[0096] According to some embodiments of this application, as shown in 4, the electronic device 200 further includes: a flexible screen 220, which covers the first housing 212 and the second housing 214 and deforms along with the first housing 212 and the second housing 214.

[0097] In this embodiment, the flexible screen 220 of the electronic device 200 includes a transition section in the middle and first folding sections and second folding sections on both sides. After the flexible screen 220 is assembled, the transition section is opposite to the limiting seat 110 and the rotating member 120. The first folding sections are connected to the first housing 212, and the second folding sections are connected to the second housing 214. When the flexible screen 220 is in the unfolded state, the first folding section, the second folding section, and the transition section are flush, forming a complete plane. When the flexible screen 220 is in the folded state, the first folding section and the second folding section are opposite and parallel, and the transition section is vertically connected between the first folding section and the second folding section.

[0098] By incorporating this flexible screen 220, users can expand the display area by bending the first housing 212 and the second housing 214 when a larger screen is needed, thus meeting document processing or video viewing requirements. Conversely, in standby mode or when handling simple information, users can close the flexible screen 220 by bending the first housing 212 and the second housing 214, thereby reducing the difficulty of holding and storing the electronic device 200 and providing greater convenience. Therefore, by incorporating the flexible screen 220, users' needs in multiple scenarios can be met, providing them with more choices and ultimately optimizing their user experience.
