DETAILED DESCRIPTION

[0040] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0043] In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0044] The folding screen mobile phone has a structure similar to that of a hinge and can be bent. Before the folding module is shipped, the water droplet bending area needs to be observed, the actual water droplet morphology is compared with the simulated water droplet morphology, and the displacement of each layer of the folding module can be observed to evaluate the bending performance of the folding module material. When the folding module is bent for testing, the folding module can be placed on the bending jig to bend the folding module by bending the bending jig.

[0045] Some manufacturers adopt the method of artificial bending jig to make the bending jig bend, but it needs to test the folding module for many times, so the workload is large, and some manufacturers adopt the driving device to drive the bending jig to bend. In the process of driving the bending jig to bend and turn over, the movement end of the driving device and the rotating plate of the bending jig cannot be completely synchronized, which causes the driving device to be easy to jam, not smooth, and even easy to damage the bending jig when driving the bending jig to bend and turn over.

[0046] In order to alleviate or solve the above technical problems, the present application provides a kind of bending jig driving device, including first fixed structure 151, driving piece 11, swing structure 12, compensation structure 13 and second fixed structure 152, first fixed structure 151 and second fixed structure 152 are fixed to the two mutually rotating plates of bending jig 20, driving piece 11 drives swing structure 12 swing, compensation structure 13 can compensate the displacement or angle between swing structure 12 and second fixed structure 152, and then the bending of bending jig 20 can be more smooth to turn over, so as to avoid the situation of jam or damage jig.

[0047] Now the bending jig driving device provided by the embodiment of the present application will be described. The bending jig driving device is used to drive the bending jig 20 to bend and turn over, and the folding module is placed on the bending jig 20, so that the water drop morphology of the folding module during folding and the displacement of each layer of the folding module can be observed. Among them, the bending jig 20 includes a first rotating plate 21 and a second rotating plate 22 connected with each other, and the bending jig driving device is used to make the first rotating plate 21 and the second rotating plate 22 rotate relative to each other.

[0048] Please refer to Figures 1 to 3 , the bending jig driving device includes first fixed structure 151 for fixed connection with the first rotating plate 21, driving piece 11, swing structure 12 driven to rotate by driving piece 11, compensation structure 13 in sliding connection with swing structure 12, and second fixed structure 152 for fixed connection with the second rotating plate 22, and compensation structure 13 is in rotating connection with second fixed structure 152.

[0049] The first fixed structure 151 is fixedly arranged, and the first fixed structure 151 can be a plate structure, a bracket structure, etc., and its specific structure shape is not limited here. The first fixed structure 151 is used for fixed connection with the first rotating plate 21 of the bending jig 20, and it can also be understood that the first rotating plate 21 of the bending jig 20 is supported and fixed on the first fixed structure 151, and correspondingly, the first rotating plate 21 is also fixedly arranged.

[0050] The driving member 11 is a power device capable of outputting rotary motion, and drives the second rotary plate 22 to rotate relative to the first rotary plate 21 through the transmission of the swing structure 12 and the compensation structure 13. The driving member 11 can be a motor, a motor, a steering gear, etc.

[0051] The swing structure 12 is driven to rotate by the driving member 11. Specifically, the movement output end of the driving member 11 is fixedly connected with the swing structure 12, and when the driving member 11 works, the swing structure 12 rotates with the driving member 11. The swing structure 12 can be an integrally formed structure, or a structure composed of separate parts connected with each other.

[0052] The compensation structure 13 is used to compensate for the position difference and angle difference between the swing structure 12 and the second rotary plate 22 when the second rotary plate 22 rotates relative to the first rotary plate 21, so as to avoid the situation that the swing structure 12 interferes with the second rotary plate 22, causing jamming or damage to the bending jig 20 when the bending jig driving device works. Specifically, the compensation structure 13 is slidingly connected with the swing structure 12, and the compensation structure 13 is rotatably connected with the second fixed structure 152. In this way, when the first rotary plate 21 rotates relative to the second rotary plate 22, the compensation structure 13 can compensate for the position difference and angle difference between the swing structure 12 and the second rotary plate 22.

[0053] The second fixed structure 152 is used to fix with the second rotary plate 22, and when the second rotary plate 22 flips relative to the first rotary plate 21, the second fixed structure 152 moves synchronously with the second rotary plate 22.

[0054] It should be noted that in the bending jig 20, the first rotary plate 21 and the second rotary plate 22 rotate relative to each other to approach the folded state. In the folded state, the larger side of the first rotary plate 21 exposed is the first fixed side, and the larger side of the second rotary plate 22 exposed is the second fixed side. The first fixed structure 151 is fixed to the first fixed side of the first rotary plate 21, and the second fixed structure 152 is fixed to the second fixed side of the second rotary plate 22.

[0055] The bending jig driving device in the above embodiment comprises a first fixing structure 151, a second fixing structure 152, a driving piece 11, a swinging structure 12 and a compensation structure 13, the first fixing structure 151 and the second fixing structure 152 are respectively used for fixing the first rotating plate 21 and the second rotating plate 22 of the bending jig 20, the driving piece 11 is used for driving the swinging structure 12 to swing, the swinging of the swinging structure 12 can drive the second rotating plate 22 to rotate relative to the first rotating plate 21, and the bending of the bending jig 20 is realized. Moreover, the swinging structure 12 is in sliding connection with the compensation structure 13, the compensation structure 13 is in rotary connection with the second fixing structure 152, therefore, when the swinging structure 12 rotates, the swinging structure 12 can slide relative to the compensation structure 13, and the compensation structure 13 can rotate relative to the second fixing structure 152, so that the jamming of the bending jig driving device in use can be reduced, and the bending jig 20 can be prevented from being damaged.

[0056] In some embodiments of the present application, referring to Figure 2 and Figure 3 , the compensation structure 13 comprises a rotary compensation piece 132 in rotary connection with the second fixing structure 152 and a sliding compensation part 131 in sliding connection with the swinging structure 12, and the sliding compensation part 131 is arranged on the rotary compensation piece 132. The rotary compensation piece 132 can rotate relative to the second fixing structure 152, and thus the angle difference between the swinging structure 12 and the second fixing structure 152 can be compensated. Specifically, when the second fixing structure 152 rotates with the second rotating plate 22, the swinging structure 12 rotates by an angle A, and the second fixing structure 152 and the second rotating plate 22 rotate by an angle B. Since the second fixing structure 152 is located at the end of the transmission chain and rotates relatively laggingly, generally A is greater than B. If the swinging structure 12 and the second fixing structure 152 are directly connected, the jamming phenomenon will occur. Through the arrangement of the rotary compensation piece 132, the angle difference between the swinging structure 12 and the second fixing structure 152 can be compensated, and the transmission connection is more stable. The sliding compensation part 131 is in sliding connection with the swinging structure 12. When the swinging structure 12 rotates, the end of the swinging structure 12 close to the second fixing structure 152 will be offset from the second fixing structure 152. Through the arrangement of the sliding compensation part 131, the displacement difference between the end of the swinging structure 12 close to the second fixing structure 152 and the second fixing structure 152 can be compensated. Specifically, when the swinging structure 12 rotates, the sliding compensation part 131 will slide relative to the swinging structure 12, change the relative position between the compensation structure 13 and the swinging structure 12, and make the transmission connection more smooth.

[0057] When the driving member 11 drives the swing structure 12 to drive the second fixed structure 152 (the second rotating plate 22) to rotate relative to the first fixed structure 151 (the second rotating plate 22), the sliding compensation part 131 can slide relative to the swing structure 12 to compensate for the displacement difference between the swing structure 12 and the second fixed structure 152, and the rotating compensation part 132 can rotate relative to the second fixed structure 152 to compensate for the angle difference between the swing structure 12 and the second fixed structure 152, so that the transmission connection between the swing structure 12 and the second fixed structure 152 can be smoother, and the jamming phenomenon can be reduced.

[0058] In some embodiments, the swing structure 12 is provided with a sliding groove 1221, and the sliding compensation part 131 is in the shape of a rod and is arranged through the sliding groove 1221. In this embodiment, the sliding compensation part 131 is a sliding structure, and correspondingly, the swing structure 12 is provided with the sliding groove 1221, so that the sliding connection between the swing structure 12 and the compensation structure 13 can be realized.

[0059] When the swing structure 12 rotates, the sliding compensation part 131 moves along the sliding groove 1221, so that the swing structure 12 can avoid the jamming phenomenon.

[0060] Optionally, the cross section of the sliding compensation part 131 is in the same shape as the cross section of the sliding groove 1221. For example, the cross section of the sliding compensation part 131 and the cross section of the sliding groove 1221 are both square, or the cross section of the sliding compensation part 131 and the cross section of the sliding groove 1221 are both circular, etc.

[0061] Optionally, the sliding compensation part 131 is fixedly connected with the rotating compensation part 132. For example, the sliding compensation part 131 is integrally formed with the rotating compensation part 132. Alternatively, the sliding compensation part 131 and the rotating compensation part 132 are separately formed and then fixedly connected with each other.

[0062] Optionally, the two ends of the sliding compensation part 131 respectively extend out of the sliding groove 1221 and are respectively connected to the opposite sides of the rotating compensation part 132 (such as the arc-shaped part 1322) through a connecting segment or the like.

[0063] In some embodiments, the swing structure 12 is provided with a sliding rod 122, and the sliding compensation part 131 is a matching groove, so that when the swing structure 12 rotates, the rotating compensation part 132 can slide relative to the swing structure 12. In this embodiment, the sliding compensation part 131 is a groove-shaped structure, and the sliding compensation part 131 can be arranged on the rotating compensation part 132.

[0064] In some embodiments of the present application, please refer to Figures 1 to 3, the rotating compensation piece 132 comprises a connecting rod 1321 and an arc-shaped part 1322, the connecting rod 1321 is connected to the second fixed structure 152, the arc-shaped part 1322 has a circular arc surface 1323 for abutting against the second fixed structure 152, and the center axis of the circular arc surface 1323 coincides with the rotating center axis of the rotating compensation piece 132. The connecting rod 1321 is used for connecting the second fixed structure 152 and the arc-shaped part 1322, and the connecting rod 1321 is a rod-shaped structure. The arc-shaped part 1322 has the circular arc surface 1323, and the circular arc surface 1323 abuts against the second fixed structure 152. When the rotating compensation piece 132 rotates relative to the second fixed structure 152, the circular arc surface 1323 rolls on the second fixed structure 152, thereby changing the included angle between the rotating compensation piece 132 and the second fixed structure 152. The rotating center axis of the rotating compensation piece 132 is the rotating center axis of the rotating compensation piece 132 relative to the second fixed structure 152. The center axis of the circular arc surface 1323 coincides with the rotating center axis of the rotating compensation piece 132, so that the circular arc surface 1323 sequentially contacts the second fixed structure 152 at each position in the circumferential direction of the rotating compensation piece 132 when the rotating compensation piece 132 rotates, thereby ensuring smooth movement.

[0065] By abutting the arc-shaped part 1322 against the second fixed structure 152, the rotation of the rotating compensation piece 132 relative to the second fixed structure 152 is the rolling of the arc-shaped part 1322 on the second fixed structure 152. Therefore, the movement of the rotating compensation piece 132 is more stable, and the rotating compensation piece 132 does not shake relative to the hinge connection or other rotating connection mode, and the rotation of the second rotating plate 22 is more stable.

[0066] In some embodiments, the arc-shaped part 1322 is a block-shaped structure, at least part of the circumferential side of the arc-shaped part 1322 is the circular arc surface 1323, and the other circumferential side of the arc-shaped part 1322 can be an arc surface or a plane.

[0067] In some embodiments of the present application, please refer to Figure 2 and Figure 3 , the second fixed structure 152 protrudes a hinge part 1521 on the side facing the rotating compensation piece 132, the connecting rod 1321 is arranged in the hinge part 1521, and the number of the arc-shaped parts 1322 is two, which are arranged at the two ends of the connecting rod 1321. The second fixed structure 152 is provided with the hinge part 1521 on the side facing the rotating compensation piece 132, so as to facilitate the connection between the second fixed structure 152 and the rotating compensation piece 132. The connecting rod 1321 is arranged in the hinge part 1521, so that the connecting rod 1321 is arranged in a spaced manner with the second fixed structure 152, and the circular arc surface 1323 of the arc-shaped part 1322 needs to be located between the second fixed structure 152 and the connecting rod 1321. In this way, the circular arc surface 1323 has sufficient design space. The connecting rod 1321 is rotatably connected with the hinge part 1521.

[0068] The hinged part 1521 is arranged to separate the connecting rod 1321 from the second fixing structure 152, and the circular arc surface 1323 of the arc-shaped part 1322 fixed on the connecting rod 1321 has sufficient arrangement space. Moreover, the number of the arc-shaped parts 1322 is two, so that the rotating compensation part 132 has two contact positions with the second fixing structure 152, and the rolling of the rotating compensation part 132 on the second fixing structure 152 is more stable.

[0069] In some embodiments, the connecting rod 1321 is arranged in a rod shape and extends along the length direction of the second fixing structure 152, so that the two arc-shaped parts 1322 are closer to the two ends of the second fixing structure 152 in the length direction, and can abut against the two ends of the second fixing structure 152 in the length direction, so that the rotation of the rotating compensation part 132 is more stable.

[0070] In some embodiments, the connecting rod 1321 is fixedly connected with the hinged part 1521, and the arc-shaped part 1322 is rotatably connected with the connecting rod 1321. When the driving part 11 drives the swing structure 12 to rotate, the arc-shaped part 1322 rolls along the second fixing structure 152 under the driving of the sliding compensation part 131, and the connecting rod 1321 and the second fixing structure 152 remain relatively fixed. In this embodiment, the connecting rod 1321 passes through the hinged part 1521, and the connecting rod 1321 and the hinged part 1521 are fixed with each other, and the connecting rod 1321 serves to connect the two arc-shaped parts 1322. One end of the connecting rod 1321 extends into the arc-shaped part 1322, but the arc-shaped part 1322 can rotate relative to the connecting rod 1321.

[0071] In some embodiments, the connecting rod 1321 is rotatably connected with the hinged part 1521, and the arc-shaped part 1322 is fixedly connected with the connecting rod 1321. When the driving part 11 drives the swing structure 12 to rotate, the arc-shaped part 1322 rolls along the second fixing structure 152 under the driving of the sliding compensation part 131, and the connecting rod 1321 moves synchronously with the arc-shaped part 1322. In this embodiment, the connecting rod 1321 passes through the hinged part 1521, but the connecting rod 1321 and the hinged part 1521 are movably connected, and can move relative to the hinged part 1521.

[0072] In some embodiments of the present application, please refer to Figures 1 to 3, the sliding direction of the swing structure 12 relative to the compensation structure 13 is perpendicular to the rotation axis of the swing structure 12, and the rotation axis of the compensation structure 13 relative to the second fixed structure 152 is parallel to the rotation axis of the swing structure 12. The rotation axis of the first rotation plate 21 and the second rotation plate 22 in the bending jig 20 is a first rotation axis, the rotation axis of the swing structure 12 is a second rotation axis, and the first rotation axis and the second rotation axis are parallel to the first direction. When the swing structure 12 rotates, due to the bending and overturning of the bending jig 20, the swing structure 12 will have a displacement difference with the second fixed structure 152 in the second direction, and the sliding compensation part 131 will compensate for the displacement difference by sliding relative to the swing structure 12 in the second direction; at the same time, the swing structure 12 will have an angle difference with the second fixed structure 152 in the first direction, and the rotation compensation part 132 will compensate for the angle difference by rotating relative to the second fixed structure 152. The first direction and the second direction are perpendicular to each other.

[0073] The sliding direction of the swing structure 12 relative to the compensation structure 13 is perpendicular to the rotation axis of the swing structure 12, which can compensate for the displacement difference between the swing structure 12 and the second fixed structure 152 in the sliding direction; and the rotation axis of the compensation structure 13 relative to the second fixed structure 152 is parallel to the rotation axis of the swing structure 12, which can compensate for the angle difference between the swing structure 12 and the second fixed structure 152 when rotating around the rotation axis.

[0074] In some embodiments, in the bending jig 20, the first rotation plate 21 and the second rotation plate 22 are rotationally connected at the long edges of the two, and accordingly, the first direction is parallel to the long edge of the second rotation plate 22 (the length direction of the second rotation plate 22), and the second direction is perpendicular to the long edge of the second rotation plate 22 (the length direction of the second rotation plate 22).

[0075] In some embodiments of the present application, please refer to Figures 2 to 4 The swing structure 12 includes a swing rod 121 and a sliding rod 122, one end of the swing rod 121 is connected with the movement output end of the driving part 11, the other end of the swing rod 121 is connected with the sliding rod 122, and the sliding rod 122 is slidingly arranged in the compensation structure 13. When the driving part 11 drives the swing structure 12 to swing, the swing rod 121 and the sliding rod 122 swing synchronously.

[0076] By arranging the swing rod 121, the sliding rod 122 is away from the movement output end of the driving part 11, and the movement path of the sliding rod 122 is close to the movement path of the second fixed structure 152 and the second rotation plate 22.

[0077] In some embodiments, the length direction of the sliding rod 122 is parallel to the rotation center axis of the swing structure 12. In this way, when the swing structure 12 rotates, the movement path of the sliding rod 122 is cylindrical, which is the same as the movement path of the second rotation plate 22, and is more matched with the movement path of the second rotation plate 22, reduces the jamming, and can also reduce the structural complexity of the compensation structure 13.

[0078] Optionally, the swing structure 12 is arranged in an L shape.

In this way, both ends of the sliding compensation part 131 of the compensation structure 13 can extend out of the sliding groove 1221 and be connected with the arc-shaped part 1322 of the compensation structure 13, so that the swing structure 12 can be limited to prevent the swing structure 12 and the compensation structure 13 from being separated from each other.

[0082] In some embodiments, the number of the arc-shaped parts 1322 of the compensation structure 13 is multiple, and correspondingly, the number of the sliding compensation parts 131 and the number of the sliding grooves 1221 are the same as the number of the arc-shaped parts 1322, and the two sliding grooves 1221 are sequentially and spaced apart along the direction of the rotation center axis of the swing structure 12. In this way, the relative sliding of the sliding rod 122 and the compensation structure 13 can be more stable, and the sliding rod 122 will not be inclined relative to the rotation center axis of the swing structure 12.

[0083] Optionally, the number of the sliding compensation parts 131, the number of the sliding grooves 1221, and the number of the arc-shaped parts 1322 are two, three, or the like.
