[0044] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0045] Please refer to the following Figures 1 to 11 A hinge, a display module and a terminal device according to an embodiment of the present invention are described.

[0046] like Figures 1 to 8 As shown, the hinge according to the embodiment of the present invention comprises: a base 1, a transmission device 2 and a plate assembly 3. The base 1 is arranged along a first direction (such as Figure 1 The transmission device 2 extends in the direction A in the first direction, and includes two groups of rotating components 21. The two groups of rotating components 21 are arranged on both sides of the base 1 along a direction orthogonal to the first direction.

[0047] like Figure 2 and Figure 3As shown, the rotating component 21 includes a first rotating arm 211, a second rotating arm 212 and a linkage member 214. One end of the first rotating arm 211 (such as Figure 2 The first rotating arm 211 is adjacent to the base 1 at one end thereof and is pivotally connected to the base 1. The other end of the first rotating arm 211 (eg Figure 2 The first rotating arm 211 (one end away from the base 1) is pivotally connected to the linkage member 214, and one end of the second rotating arm 212 is pivotally connected to the base 1.

[0048] The plate assembly 3 includes two support plates 31, and the two support plates 31 correspond to two rotating parts 21 respectively. The rotating part 21 is located on one side of the support plate 31 in the thickness direction, and the other side of the support plate 31 is used to support the screen 4. The linkage 214 is pivotally connected to the support plate 31, and the second rotating arm 212 is slidably connected to the support plate 31.

[0049] It can be understood that the second rotating arm 212 and the first rotating arm 211 are arranged at intervals along the first direction, and the first rotating arm 211 is closer to the outer edge of the screen 4 than the second rotating arm 212. For example, the second rotating arm 212 is located in the middle of the support plate 31, so that the guiding and supporting effects of the second rotating arm 212 can be improved.

[0050] According to the hinge of the embodiment of the present invention, since the rotating part 21 is located on one side of the thickness direction of the support plate 31, the support plate 31 can shield the rotating part 21, so that the frame of the terminal device is not limited by the size of the rotating part 21, which is conducive to reducing the frame of the terminal device. And since one end of the second rotating arm 212 is rotatably connected to the base 1 and the other end is slidably connected to the support plate 31, it can provide further support and guidance for the movement of the support plate 31, which is conducive to improving the structural strength of the hinge and improving the stability of the hinge structure.

[0051] In addition, the hinge of the embodiment of the present invention adopts the above-mentioned structure arrangement of the transmission device 2, and can drive the support plate 31 to rotate through the first rotating arm 211, the second rotating arm 212 and the linkage 214, so that the folded shape of the screen 4 can be roughly in the shape of a water drop. In other words, since the second rotating arm 212 and the support plate 31 are slidably matched, the support plate 31 can achieve thickness difference compensation when folding, and the screen 4 is prevented from being affected by tension or compression, so that the mechanism controls the water drop shape of the screen 4. Therefore, the transmission device 2 of the hinge of the embodiment of the present invention has a simple structural design, requires fewer parts, and has higher stability.

[0052] In some embodiments, Figures 2 to 4As shown, the rotating component 21 also includes a first fixing seat 215, which is mounted on the base 1. For example, the first fixing seat 215 can be detachably connected to the base 1, or the first fixing seat 215 can also be directly formed on the base 1. A first track groove 2151 is provided on the first fixing seat 215, and the first track groove 2151 extends along the first arc, and the axis of the first track groove 2151 is in the same direction as the first direction. One end of the first rotating arm 211 has a first mounting portion 2111, and the first mounting portion 2111 is pivotably matched with the first track groove 2151 along the first arc. The other end of the first rotating arm 211 can be pivotally connected to the linkage member 214 through a pin 217.

[0053] In one example, if Figures 2 to 4 As shown, there are two first track grooves 2151, and the two first track grooves 2151 are arranged at intervals along the first direction on the first fixing seat 215. There are two first mounting portions 2111, and the two first mounting portions 2111 correspond to the two first track grooves 2151. It can be understood that the first track grooves 2151 are respectively arranged on both sides of the first rotating arm 211 along the first direction and correspond to the first mounting portions 2111 one by one, so as to improve the stability of the first rotating arm 211 when rotating relative to the first fixing seat 215, which is conducive to extending the service life of the hinge.

[0054] In some embodiments, Figures 2 to 4 As shown, the rotating component 21 further includes a second fixing seat 216, which is mounted on the base 1 and is spaced apart from the first fixing seat 215 along the first direction. For example, the second fixing seat 216 can be detachably connected to the base 1, or the second fixing seat 216 can also be directly formed on the base 1. The second fixing seat 216 is provided with a second track groove 2161, which extends along a second arc line, and the axis of the second track groove 2161 is in the same direction as the first direction. The second rotating arm 212 is provided with a second mounting portion 2121, which is pivotally matched with the second track groove 2161 along the second arc line.

[0055] In one example, if Figures 2 to 4 As shown, there are two second track grooves 2161, and the two second track grooves 2161 are arranged at intervals along the second direction on the second fixing seat 216. There are two second mounting portions 2121, and the two second mounting portions 2121 correspond to the two second track grooves 2161 one by one. It can be understood that the second track grooves 2161 are respectively arranged on both sides of the second rotating arm 212 along the first direction and correspond to the first mounting portions 2111 one by one, so as to improve the stability of the second rotating arm 212 when rotating relative to the second fixing seat 216, which is conducive to extending the service life of the hinge.

[0056] Alternatively, if Figure 6As shown, the linkage member 214 is provided with a third track groove 2141, the third track groove 2141 extends along a third arc, the third arc protrudes in a direction away from the support plate 31, and the support plate 31 is provided with a third mounting portion 311, the third mounting portion 311 slides with the third track groove 2141 along the third arc. For example, the third mounting portion 311 is an arc-shaped sliding block, and the sliding block is directly formed on the support plate 31. The hinge of the embodiment of the present invention is configured as the above structure by setting the support plate 31 and the linkage member 214 so that the support plate 31 and the linkage member 214 can both rotate and slide relative to each other, ensuring that the movement of the support plate 31 is more accurate and reliable, and the structural design is simple and convenient to process.

[0057] Alternatively, if Figure 2 and Figure 3 As shown, the support plate 31 is provided with a fourth track groove 312, the fourth track groove 312 extends along a fourth straight line, the fourth straight line is orthogonal to the first direction, and the second rotating arm 212 is provided with a fourth mounting portion 2122, and the fourth mounting portion 2122 slides with the fourth track groove 312 along the fourth straight line. It can be understood that the fourth track groove 312 extends along the width direction of the support plate 31, and the fourth track groove 312 can be a dovetail groove or a limiting groove with a "convex" cross section, or the fourth track groove 312 can be a channel with a rectangular cross section, and the fourth mounting portion 2122 cooperates with the fourth track groove 312 so that the support member can slide relative to the second rotating arm 212, so that the shape of the hinge after folding is closer to a water drop shape, thereby improving the support effect of the screen 4.

[0058] In some embodiments, Figures 2 to 4 As shown, the rotating component 21 also includes a third rotating arm 213, which is arranged between the first rotating arm 211 and the second rotating arm 212 along the first direction, one end of the third rotating arm 213 is pivotally connected to the base 1, and the other end of the third rotating arm 213 is slidably connected to the linkage member 214.

[0059] It can be understood that the rotation axis of the first rotating arm 211 and the base 1, the rotation axis of the first rotating arm 211 and the linkage member 214, and the rotation axis of the third rotating arm 213 and the base 1 are all in the same direction as the first direction. The sliding direction of the third rotating arm 213 and the linkage member 214 is orthogonal to the first direction. When the rotating component 21 moves from the unfolded position to the folded position, the first rotating arm 211 rotates relative to the base 1 to drive the linkage member 214 to rotate relative to the base 1, and because the third rotating arm 213 and the linkage member 214 slide together, the hinge can achieve thickness difference compensation when folded, avoiding the screen 4 from being affected by tension or extrusion, and the structural design is simple, and the support effect on the screen 4 is better.

[0060] Specifically, Figures 2 to 4As shown, the linkage member 214 is provided with a fifth track groove 2142, which extends along a fifth straight line, which is orthogonal to the first direction, and the third rotating arm 213 is provided with a fifth mounting portion 2131, which slides with the fifth track groove 2142 along the fifth straight line. For example, the fifth track groove 2142 may be a dovetail groove or a limiting groove with a "convex" cross section, and the fifth mounting portion 2131 cooperates with the fifth track groove 2142, so that the linkage member 214 can slide relative to the third rotating arm 213, further improving the effect of the hinge on supporting the screen 4.

[0061] In some embodiments, Figures 5 to 8 As shown, the plate assembly 3 also includes an intermediate connecting plate 32, which is arranged between the two support plates 31 and located on the base 1. When the rotating part 21 moves from the folded position to the unfolded position, the first rotating arm 211 can drive the intermediate connecting plate 32 to move in a direction away from the base 1.

[0062] According to the hinge of the embodiment of the present invention, when the rotating part 21 moves from the folded position to the unfolded position, the first rotating arm 211 can drive the middle connecting plate 32 to move in the direction away from the base 1 to increase the height of the middle connecting plate 32, so that the middle connecting plate 32 can be fully fitted with the screen 4, thereby improving the supporting effect of the middle connecting plate 32. When the rotating part 21 moves from the unfolded position to the folded position, the middle connecting plate 32 can be lowered, thereby providing ample space for the folding of the screen 4, thereby avoiding the problem of interference between the screen 4 and the middle connecting plate 32 of the hinge during the bending process, and can better support the shape of the screen 4 when folded, which is conducive to extending the service life of the screen 4.

[0063] Alternatively, if Fig.11 As shown, the plate assembly 3 further includes an elastic member 33, which is disposed between the middle connecting plate 32 and the base 1. The elastic member 33 has an elastic force that drives the middle connecting plate 32 to move toward the direction close to the base 1. When the rotating component 21 moves from the unfolded position to the folded position, the elastic member 33 drives the middle connecting plate 32 to move toward the direction close to the base 1. Since the elastic member 33 drives the middle connecting plate 32 to move toward the direction close to the base 1, when the rotating component 21 moves from the unfolded position to the folded position, the middle connecting plate 32 can move toward the direction close to the base 1 under the action of the elastic force, thereby improving the linkage effect of the middle connecting plate 32, and the structural design is simple, which is convenient for processing and manufacturing.

[0064] Alternatively, if Figure 7As shown, the first rotating arm 211 is provided with a contact portion 2112, which is provided between the intermediate connecting plate 32 and the base 1. In the folded position, the contact portion 2112 is spaced apart from the intermediate connecting plate 32. In the unfolded position, the contact portion 2112 abuts against the intermediate connecting plate 32, and the upper end surface of the intermediate connecting plate 32 is flush with the upper end surface of the support plate 31. It can be understood that the contact portion 2112 is provided on the end surface of the first mounting portion 2111 of the first rotating arm 211. When the first rotating arm 211 moves from the folded position to the unfolded position, the contact portion 2112 moves toward the intermediate connecting plate 32 to gradually lift the intermediate connecting plate 32 and make it flush with the support plate 31. When the first rotating arm 211 moves from the unfolded position to the folded position, the contact portion 2112 rotates and moves downward, and the intermediate connecting plate 32 can move downward synchronously under the action of the elastic member 33. The hinge of the embodiment of the present invention adopts the above structure to control the lifting and lowering of the middle connecting plate 32, which can avoid the interference between the screen 4 and the support plate 31 of the hinge during the bending process, and avoid the problem of failure of the screen 4 due to stress concentration.

[0065] Alternatively, if Figure 4 , Figure 6 and Fig.11 As shown, the lower end surface of the intermediate connecting plate 32 is provided with a guide column 321, and the base 1 or the first fixing seat 215 is provided with a guide hole 11. The guide column 321 is slidably fitted in the guide hole 11 along the moving direction of the intermediate connecting plate 32, and the elastic member 33 is provided between the guide column 321 and the guide hole 11. For example, there can be a plurality of guide columns 321, and the plurality of guide columns 321 are arranged along the length direction of the intermediate connecting plate 32 (such as Figure 1 The guide holes 11 are arranged at intervals (in the A direction), and there are multiple guide holes 11, which correspond one to one with multiple guide posts 321. The elastic member 33 can be arranged in one or more guide holes 11. The hinge of the embodiment of the present invention can improve the support and guiding effect of the middle connecting plate 32 and improve the accuracy of the movement of the middle connecting plate 32 by setting multiple guide posts 321.

[0066] For example, Figure 6 and Fig.11 As shown, a screw 34 is provided at the lower end of the guide column 321, and the end cap of the screw 34 can abut against the upper edge of the guide hole 11, thereby preventing the guide column 321 from slipping out of the guide hole 11. The elastic member 33 is a spring, which is sleeved on the guide column 321, and one end of the spring abuts against the end cap of the screw 34, and the other end of the spring abuts against the upper edge of the guide hole 11. The hinge of the embodiment of the present invention connects the guide column 321 and the guide hole 11 in the above manner, which can facilitate operators to assemble the intermediate connecting plate 32.

[0067] In some embodiments, Figures 2 to 4As shown, a gear portion 2132 is provided at one end of the third rotating arm 213, and the transmission device 2 further includes a gear transmission pair 22, which is provided on the base 1, and the gear transmission pair 22 is meshed with the gear portion 2132 to drive the two groups of rotating components 21 to rotate synchronously relative to the base 1. Specifically, the gear transmission pair 22 includes two first gears 221, which are meshed with each other, and each first gear 221 is meshed with the corresponding gear portion 2132, so that the rotating components 21 on both sides of the base 1 can have better synchronization when folding, and the transmission is accurate, and the use effect is better.

[0068] In some embodiments, Figure 4 As shown, the transmission device 2 also includes a damping component 23, which is arranged on the base 1. The damping component 23 includes a convex tooth seat 231 and an elastic body 232. One end of the third rotating arm 213 is provided with a convex tooth portion 2133 along the first direction. The convex tooth seat 231 is meshed with the convex tooth portion 2133, and the elastic body 232 abuts against the convex tooth seat 231 to press the convex tooth portion 2133 along the direction toward the convex tooth portion 2133.

[0069] It is understandable that if Figure 4 As shown, the third rotating arm 213 can be suspended at any angle by the convex tooth portion 2133 and the convex tooth seat 231. In other words, the third rotating arm 213 can automatically open and close within the angle range of 0° and 180°. For example, in order to ensure that the convex tooth portion 2133 can better mesh with the convex tooth seat 231 during the movement of the hinge without shaking, the gear portion 2132 and the convex tooth portion 2133 can be made into one piece, thereby ensuring the stability of the third rotating arm 213 during transmission.

[0070] For example, Figure 4 As shown, the elastomer 232 can be a spring. The elastomer 232 is in a pre-compressed state after assembly. During the bending process of the hinge, the convex tooth portion 2133 provides a damping force for the rotation of the third rotating arm 213, so that the hinge can hover at any position, thereby improving the user experience.
