Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0039] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0043] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0044] See Figures 1-6 As shown, this application provides a folding mechanism 100, which includes a first rotating plate 110, a second rotating plate 120 and a base 130. The folding mechanism 100 is used to flip and fold a product to be folded, such as a flexible screen.

[0045] The base 130 has flip modules 140 at both opposite ends. If the base 130 is a long strip structure, the flip modules 140 are provided at both ends of its length. The base 130 fixes the flip modules 140, and the two flip modules 140 can ensure the stability of the product to be flipped during the folding process. The flip module 140 includes a first rotating component 141 and a second rotating component 142. The first rotating plate 110 and the second rotating plate 120 are used to support the product to be flipped. For example, if a part of the product to be flipped is supported on the first rotating plate 110 by means of adhesion, rest, or clipping, and another part of the product to be flipped is supported on the second rotating plate 120 by means of adhesion, rest, or clipping, the first rotating component 141 and the second rotating component 142 respectively drive the first rotating plate 110 and the second rotating plate 120 to move towards each other or away from each other, so as to complete the flipping and folding operation of the product to be flipped.

[0046] The first rotating plate 110 is provided with a first rotating groove 111 and a first sliding part 112, and the second rotating plate 120 is provided with a second rotating groove 121 and a second sliding part 122. The first rotating assembly 141 is provided with a first rotating shaft 1411 and a first mating part 1412. The first rotating shaft 1411 is movably inserted into the first rotating groove 111, and the first mating part 1412 is slidably fitted into the first sliding part 112. If the first rotating groove 111 penetrates at least a portion of the first rotating plate 110, the first sliding part 112 is an arc-shaped block provided on the first rotating plate 110, and the first mating part 1412 is an arc-shaped groove provided on the first rotating assembly 141. The second rotating assembly 142 is provided with a second rotating shaft 1421 and a second mating part 1422. The second rotating shaft 1421 is movably inserted into the second rotating groove 121, and the second mating part 1422 is slidably fitted into the second sliding part 122. For example, the second rotating groove 121 penetrates at least part of the second rotating plate 120, the second sliding part 122 is an arc-shaped block provided on the second rotating plate 120, and the second mating part 1422 is an arc-shaped groove provided on the second rotating assembly 142.

[0047] The aforementioned folding mechanism 100 is used to flip and fold the product to be folded. Specifically, the first rotating assembly 141 and the second rotating assembly 142 respectively rotate the first rotating plate 110 and the second rotating plate 120 to complete the flipping and folding operation of the product. The rotation trajectory of the first rotating plate 110 is limited by the cooperation of the first rotating shaft 1411 with the first rotating groove 111 and the first sliding part 112 with the first mating part 1412. Similarly, the rotation trajectory of the second rotating plate 120 is limited by the cooperation of the second rotating shaft 1421 with the second rotating groove 121 and the second sliding part 122 with the second mating part 1422. This ensures that the rotation trajectories of the first rotating plate 110 and the second rotating plate 120 are unique, allowing the folding mechanism 100 to move along a predetermined rotation path during the folding process. This improves the smoothness of the product during rotation, thereby enhancing the folding efficiency and user experience.

[0048] Generally, during the rotation of a product, its trajectory is non-directional; for example, the product may rotate along... Figure 7 As shown in path a, path b, or path c, the product to be folded is prone to jamming during the folding process. Based on the above problem, in one embodiment, please refer to... Figure 8 and Figure 9 As shown, the folding mechanism 100 also includes a limiting component 150, which is disposed on the base 130. The limiting component 150 is used to limit the rotation trajectory of the first rotating plate 110 and / or the second rotating plate 120. Thus, the limiting component 150 can limit the rotation trajectory of the first rotating plate 110 and the second rotating plate 120, such as limiting the rotation trajectory of the first rotating plate 110 and the second rotating plate 120 along... Figure 7As shown in path b, the rotation angles of the first rotating plate 110 and the second rotating plate 120 change according to a predetermined trajectory. For example, the first rotating plate 110 and the second rotating plate 120 have a predetermined rotation angle α1, and there is another predetermined rotation angle α2 during the rotation. The rotation trajectory of the first rotating plate 110 and the second rotating plate 120 is unique. The folding mechanism 100 moves according to the predetermined rotation path during the folding process, which improves the smoothness of the product to be rotated during the rotation process, thereby improving the folding efficiency and user experience of the product to be rotated.

[0049] Further, see Figures 7-9 As shown, the limiting assembly 150 includes a limiting seat 151 and two limiting rods 152 disposed on the limiting seat 151. The limiting seat 151 is disposed on the base 130, and the limiting rods 152 are rotatably disposed on the limiting seat 151. The first rotating plate 110 is provided with a first guide groove 113, which penetrates at least a portion of the first rotating plate 110 in the thickness direction. The second rotating plate 120 is provided with a second guide groove 123, which penetrates at least a portion of the second rotating plate 120 in the thickness direction. One of the two limiting rods 152 is slidably inserted into the first guide groove 113, and the other of the two limiting rods 152 is slidably inserted into the second guide groove 123.

[0050] Specifically, when the first rotating plate 110 rotates, the limiting rod 152 slides within the first guide groove 113 due to the rotational force of the first rotating plate 110. By limiting the sliding path of the limiting rod 152 within the first guide groove 113, the rotation path of the first rotating plate 110 can be limited. When the second rotating plate 120 rotates, the limiting rod 152 slides within the second guide groove 123 due to the rotational force of the second rotating plate 120. By limiting the sliding path of the limiting rod 152 within the second guide groove 123, the rotation path of the second rotating plate 120 can be limited. Thus, through the sliding engagement of the limiting rod 152 with the first guide groove 113 and the sliding engagement of the limiting rod 152 with the second guide groove 123, the rotation trajectories of the first rotating plate 110 and the second rotating plate 120 are unique, which can limit the rotation angle between the first rotating plate 110 and the second rotating plate 120, so that the folding mechanism 100 moves along a predetermined rotation path during the folding process, improving the smoothness of the product to be rotated during the rotation process.

[0051] Preferably, there are multiple limiting components 150, and these multiple limiting components 150 are spaced apart along the extension direction of the base 130, which can ensure the guiding stability and reliability of the first rotating plate 110 and the second rotating plate 120 during rotation. Furthermore, the limiting components 150 are movable relative to the base 130. Thus, by moving the limiting components 150 to different positions on the base 130, the limiting rod 152 can be compatible with the insertion of the first guide groove 113 or the second guide groove 123 at different positions. For example, if the first rotating plate 110 is provided with multiple first guide grooves 113 at intervals, and the second rotating plate 120 is provided with multiple second guide grooves 123 at intervals, the limiting rod 152 can be selectively inserted into any first guide groove 113 or any second guide groove 123 to change the mating position of the limiting component 150 with the first rotating plate 110 or the second rotating plate 120, thus accommodating different rotation requirements of the product to be rotated.

[0052] For example, if multiple slots are provided at different positions on the limiting seat 151, the limiting rod 152 can be rotatably connected to any slot. By selectively connecting the limiting rod 152 to a preset slot, the position of the limiting rod 152 can be changed. Alternatively, if the limiting seat 151 has a sliding groove structure, one end of the limiting rod 152 can slide into the sliding groove structure. By sliding the limiting rod 152 within the sliding groove structure, the position of the limiting rod 152 can be changed. Alternatively, the limiting seat 151 can be slidably disposed on the base 130. By moving the limiting seat 151 relative to the base 130, the position of the limiting rod 152 can be changed. Of course, the movable connection method between the limiting component 150 and the base 130 can also be set according to the reserved space of the folding mechanism 100, the molding process, etc., and is not limited here.

[0053] In one embodiment, see Figures 1-6 As shown, the flipping module 140 also includes a fixing base 143, which is disposed on the base 130. The first rotating assembly 141 includes a first rocker arm 1413 and a first connecting plate 1414. One end of the first rocker arm 1413 is connected to the first connecting plate 1414, and the end of the first rocker arm 1413 away from the first connecting plate 1414 is rotatably disposed on the fixing base 143. That is, the two ends of the first rocker arm 1413 are respectively connected to the first connecting plate 1414 and the fixing base 143. The first rocker arm 1413 has a first rotating shaft 1411 on the side near the first connecting plate 1414, and the first connecting plate 1414 has a protruding first mating part 1412. For example, when the first rocker arm 1413 rotates relative to the fixed base 143, the first rocker arm 1413 drives the first connecting plate 1414 to rotate. Through the cooperation between the first rotating shaft 1411 and the first rotating groove 111, and between the first mating part 1412 and the first sliding part 112, the rotation trajectory of the first rotating plate 110 is limited, so that the rotation trajectory of the first rotating plate 110 is unique, thereby improving the smoothness of the first rotating plate 110 during rotation.

[0054] Similarly, the second rotating assembly 142 includes a second rocker arm 1423 and a second connecting plate 1424. One end of the second rocker arm 1423 is connected to the second connecting plate 1424, and the end of the second rocker arm 1423 away from the second connecting plate 1424 is rotatably mounted on the fixed base 143. That is, both ends of the second rocker arm 1423 are respectively connected to the second connecting plate 1424 and the fixed base 143. The second rocker arm 1423 has a second rotating shaft 1421 on the side near the second connecting plate 1424, and the second connecting plate 1424 has a protruding second mating part 1422. For example, when the second rocker arm 1423 rotates relative to the fixed base 143, the second rocker arm 1423 drives the second connecting plate 1424 to rotate. Through the cooperation between the second rotating shaft 1421 and the second rotating groove 121, and between the second mating part 1422 and the second sliding part 122, the rotation trajectory of the second rotating plate 120 is defined, so that the rotation trajectory of the second rotating plate 120 is unique, thereby improving the smoothness of the second rotating plate 120 during rotation.

[0055] Continue to refer to Figure 10 As shown, the first connecting plate 1414 is provided with a first sliding groove 1415, and the end of the first rocker arm 1413 is slidably disposed in the first sliding groove 1415. For example, if the first rocker arm 1413 is at least partially sunk into the first sliding groove 1415 and the first rocker arm 1413 can slide in the first sliding groove 1415, the degree of freedom of the first rocker arm 1413 is increased on the basis that the first rocker arm 1413 can drive the first connecting plate 1414 to move, so as to avoid the first rotating plate 110 from getting stuck during rotation and improve the smoothness of rotation of the first rotating plate 110. Similarly, the second connecting plate 1424 is provided with a second sliding groove 1425, and the end of the second rocker arm 1423 is slidably disposed in the second sliding groove 1425. For example, if the second rocker arm 1423 is at least partially sunk into the second sliding groove 1425 and the second rocker arm 1423 can slide in the second sliding groove 1425, the degree of freedom of the second rocker arm 1423 is increased on the basis that the second rocker arm 1423 can drive the second connecting plate 1424 to move, so as to avoid the bad phenomenon of jamming during the rotation of the second rotating plate 120 and improve the smoothness of the rotation of the second rotating plate 120.

[0056] Further, see Figures 1-6 and Figure 10As shown, the first rotating assembly 141 further includes a first crank 1416, one end of which is rotatably connected to a first connecting plate 1414. For example, the first crank 1416 is rotatably connected to the first connecting plate 1414 via a shaft. A first rolling part 1417 is provided on the side of the first crank 1416 away from the first connecting plate 1414. The second rotating assembly 142 further includes a second crank 1426, one end of which is rotatably connected to the first connecting plate 1414. For example, the second crank 1426 is rotatably connected to the second connecting plate 1424 via a shaft. A second rolling part 1427 is provided on the side of the second crank 1426 away from the second connecting plate 1424. The fixed base 143 is provided with a third rolling part 1431, which can roll in cooperation with the first rolling part 1417 and the second rolling part 1427. For example, the first rolling part 1417 is an arc-shaped protrusion provided on the first crank 1416, the second rolling part 1427 is an arc-shaped protrusion provided on the second crank 1426, and the third rolling part 1431 is an arc-shaped groove provided on the fixed seat 143.

[0057] In the aforementioned folding mechanism 100, during the rotation of the first rotating plate 110 and the second rotating plate 120, the first rolling part 1417, the second rolling part 1427, and the third rolling part 1431 roll in cooperation. The first crank 1416 and the first rocker arm 1413 cooperate to limit the rotation trajectory of the first rotating plate 110, and the second crank 1426 and the second rocker arm 1423 cooperate to limit the rotation trajectory of the second rotating plate 120, so that the rotation trajectories of the first rotating plate 110 and the second rotating plate 120 are unique. The folding mechanism 100 moves according to the predetermined rotation path during the folding process, improving the smoothness of the product to be rotated during the rotation process.

[0058] Specifically, see Figure 1 and Figure 2 As shown, the flipping module 140 also includes an even number of meshing gear sets 144. The first rocker arm 1413 has a first meshing portion 1418 that can mesh with the gear sets 144, and the second rocker arm 1423 has a second meshing portion 1428 that can mesh with the gear sets 144. Thus, through the meshing of the first meshing portion 1418, the gear sets 144, and the second meshing portion 1428, the first connecting plate 1414 and the second connecting plate 1424 can rotate synchronously, so that the first rotating plate 110 and the second rotating plate 120 can move synchronously in a direction that moves closer to or further away from each other.

[0059] The gear set 144 is configured with an even number of meshing gears, which ensures that the first rotating plate 110 and the second rotating plate 120 rotate in the same or opposite directions, thus achieving synchronous movement of the first rotating plate 110 and the second rotating plate 120 toward each other or away from each other. Exemplarily, the gear set 144 may include two, four, or other meshing gears; the specific number of gears included in the gear set 144 is not limited in this application.

[0060] In one embodiment, see Figure 1 and Figure 2 As shown, the folding mechanism 100 also includes a first carrier plate 160 and a second carrier plate 170. The first carrier plate 160 is connected to the first connecting plate 1414 and has a first bearing area 161 for bearing the product to be transferred. The second carrier plate 170 is connected to the second connecting plate 1424 and has a second bearing area 171 for bearing the product to be transferred. When the first carrier plate 160 is connected to the first connecting plate 1414, the first carrier plate 160 and the first rotating plate 110 are located on the same side of the base 130, and the first rotating plate 110 provides rotational support for the first carrier plate 160. Similarly, when the second carrier plate 170 is connected to the second connecting plate 1424, the second carrier plate 170 and the second rotating plate 120 are located on the same side of the base 130, and the second rotating plate 120 provides rotational support for the second carrier plate 170.

[0061] During the rotation of the folding mechanism 100, the first connecting plate 1414 and the second connecting plate 1424 can drive the first carrier plate 160 and the second carrier plate 170 to rotate synchronously in the direction of moving closer to or further away from each other, so that the product to be rotated rotates according to a preset path and realizes the flipping and folding operation of the product to be rotated.

[0062] Further, see Figure 1 and Figure 2 As shown, the first rotating plate 110 and the first carrier plate 160 are provided with a first adhesive portion 162 for fixing the product to be rotated, such as the first adhesive portion 162 being formed in the first rotating plate 110 and the first bearing area 161. The second rotating plate 120 and the second carrier plate 170 are provided with a second adhesive portion 172 for fixing the product to be rotated, such as the second adhesive portion 172 being formed in the second rotating plate 120 and the second bearing area 171. In this way, the product to be rotated is glued and fixed to the first rotating plate 110 and the first carrier plate 160 by the first adhesive portion 162, and the product to be rotated is glued and fixed to the second rotating plate 120 and the second carrier plate 170 by the second adhesive portion 172, so as to ensure that the relative position between the product to be rotated and the first rotating plate 110, the first carrier plate 160, the second rotating plate 120, and the second carrier plate 170 remains unchanged, avoiding the adverse phenomenon of displacement deviation of the product to be rotated during rotation, so that the product to be rotated can be flipped and folded to a preset state for testing.

[0063] The first adhesive portion 162 and the second adhesive portion 172 can be formed of double-sided adhesive, optical adhesive, etc. This application does not limit the specific materials used to form the first adhesive portion 162 and the second adhesive portion 172. Furthermore, compared to the conventional method where the first adhesive portion 162 and the second adhesive portion 172 are only provided at the positions of the first carrier plate 160 and the second carrier plate 170 respectively, this embodiment provides the first adhesive portion 162 and the second adhesive portion 172 at the positions of the first rotating plate 110 and the second rotating plate 120 respectively, to ensure that the product to be rotated will not experience misalignment due to relative displacement during rotation.

[0064] In one embodiment, see Figure 1 and Figure 2 As shown, the first carrier plate 160 is provided with a first limiting boss 163. Preferably, the first limiting boss 163 is integrally formed on the first carrier plate 160 by injection molding, extrusion or other methods, and the first limiting boss 163 protrudes from the surface of the first carrier plate 160 facing the second carrier plate 170 during rotation. The second carrier plate 170 is provided with a second limiting boss 173. Preferably, the second limiting boss 173 is integrally formed on the second carrier plate 170 by injection molding, extrusion or other methods, and the second limiting boss 173 protrudes from the surface of the second carrier plate 170 facing the first carrier plate 160 during rotation.

[0065] When the first carrier plate 160 and the second carrier plate 170 move toward each other, the first limiting boss 163 can abut against the second limiting boss 173. Since the first limiting boss 163 protrudes from the first carrier plate 160 and the second limiting boss 173 protrudes from the second carrier plate 170, the abutment of the first limiting boss 163 against the second limiting boss 173 prevents the first carrier plate 160 and the second carrier plate 170 from being completely fitted together, thus meeting different testing requirements.

[0066] Additionally, see Figures 1-6 As shown, this application also provides a testing device, which includes a testing fixture and a folding mechanism 100 as described in any of the above technical solutions. The folding mechanism 100 is detachably connected to the testing fixture. For example, both the first carrier plate 160 and the second carrier plate 170 are provided with bushings 180. After the first carrier plate 160 and the second carrier plate 170 are rotated to a preset angle, the bushings 180 position the connection between the first carrier plate 160, the second carrier plate 170 and the testing fixture. Then, the folding mechanism 100 is connected to the testing fixture by means of screws, snaps, etc. The product to be rotated carried by the folding mechanism 100 is tested through the testing fixture.

[0067] The aforementioned testing device, through the cooperation of the first rotating shaft 1411 and the first rotating groove 111, and the first sliding part 112 and the first mating part 1412, can limit the rotation trajectory of the first rotating plate 110. Furthermore, through the cooperation of the second rotating shaft 1421 and the second rotating groove 121, and the second sliding part 122 and the second mating part 1422, it can limit the rotation trajectory of the second rotating plate 120. This ensures that the rotation trajectories of the first rotating plate 110 and the second rotating plate 120 are unique, and the folding mechanism 100 moves along a predetermined rotation path during the folding process, improving the smoothness of the product to be folded during the rotation process, thereby improving the folding efficiency and user experience of the product to be folded.

[0068] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0069] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
