[0003] Currently, in the folding test of flexible screens, the flexible screen is usually placed on a flip-able test fixture, and the flexible screen is flipped through the test fixture. The test fixture consists of two rotating hinged plates.

[0032] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. 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.

[0033] 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.

[0034] 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.

[0035] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] 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. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0037] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. 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.

[0038] The technical solutions provided by the embodiments of this application are described below with reference to the accompanying drawings.

[0039] See Figures 1-4 As shown, this application provides a flipping mechanism 100, which includes a first rotating plate 110, a second rotating plate 120 and a base 130. The flipping mechanism 100 is used to flip and fold a product to be flipped, such as a flexible screen.

[0040] The base 130 has flip modules 140 at both opposite ends. If the base 130 is a long strip structure, the base 130 has flip modules 140 at both ends along its length. The base 130 fixes the flip modules 140, and the two flip modules 140 ensure the stability of the product to be flipped during the flipping process. The flip module 140 includes a first rotating component 141, a second rotating component 142, and a limiting component 143. The first rotating plate 110 is rotatably mounted on one side of the base 130 via the first rotating component 141, and the second rotating plate 120 is rotatably mounted on the other side of the base 130 via the second rotating component 142. The first rotating plate 110 and the second rotating plate 120 are used to carry the product to be rotated. For example, a part of the product to be rotated is carried on the first rotating plate 110 by means of sticking, resting, or clipping, and another part of the product to be rotated is carried on the second rotating plate 120 by means of sticking, resting, 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 toward each other or away from each other, so as to complete the flipping and folding operation of the product to be rotated.

[0041] Generally, during the rotation of a product, its trajectory is non-directional; for example, the product may rotate along... Figure 5 The movement along path a, b, or c, as shown, can easily cause the product to jam during the flipping process. Based on the above problem, in this embodiment, refer to... Figures 1-4 As shown, a limiting component 143 is disposed on the base 130, and the limiting component 143 is used to limit the rotation trajectory of the first rotating plate 110 and / or the second rotating plate 120. Thus, the limiting component 143 can limit the rotation trajectory of the first rotating plate 110 and the second rotating plate 120, such as limiting the first rotating plate 110 and the second rotating plate 120 along... Figure 5 As 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 flipping mechanism 100 moves according to the predetermined rotation path during the flipping process, which improves the smoothness of the product to be rotated during the rotation process, thereby improving the flipping efficiency and user experience of the product to be rotated.

[0042] In one embodiment, see Figures 1-4As shown, the flipping module 140 also includes a fixed base 144, which is disposed on the base 130. Both the first rotating assembly 141 and the second rotating assembly 142 are rotatably disposed on the fixed base 144. The limiting assembly 143 includes two limiting rods 145, which are rotatably disposed on the fixed base 144, such that the limiting rods 145 are rotatably connected to the fixed base 144 via a rotating shaft. The first rotating plate 110 is provided with a first guide groove 111, 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 121, which penetrates at least a portion of the second rotating plate 120 in the thickness direction. One of the two limiting rods 145 is slidably inserted into the first guide groove 111, and the other of the two limiting rods 145 is slidably inserted into the second guide groove 121.

[0043] Specifically, when the first rotating plate 110 rotates, the limiting rod 145 slides within the first guide groove 111 due to the rotational force of the first rotating plate 110. By limiting the sliding path of the limiting rod 145 within the first guide groove 111, the rotation path of the first rotating plate 110 can be limited. When the second rotating plate 120 rotates, the limiting rod 145 slides within the second guide groove 121 due to the rotational force of the second rotating plate 120. By limiting the sliding path of the limiting rod 145 within the second guide groove 121, the rotation path of the second rotating plate 120 can be limited. Thus, through the sliding engagement of the limiting rod 145 with the first guide groove 111 and the sliding engagement of the limiting rod 145 with the second guide groove 121, 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 flipping mechanism 100 moves along a predetermined rotation path during the flipping process, improving the smoothness of the product to be rotated during the rotation process.

[0044] Preferably, see Figures 1-4 As shown, the limiting rod 145 is movable relative to the fixed base 144. Thus, by moving the limiting rod 145 to different positions on the fixed base 144, the limiting rod 145 can be compatible with the insertion of the first guide groove 111 or the second guide groove 121 at different positions. For example, if the first rotating plate 110 is provided with multiple first guide grooves 111 at intervals, and the second rotating plate 120 is provided with multiple second guide grooves 121 at intervals, the limiting rod 145 can be selectively inserted into any first guide groove 111 or any second guide groove 121 to change the mating position of the limiting component 143 with the first rotating plate 110 or the second rotating plate 120, thus accommodating different rotation requirements of the product to be rotated.

[0045] For example, if multiple slots are provided at different positions on the fixed base 144, the limiting rod 145 can be rotatably connected to any slot. By selectively connecting the limiting rod 145 to a preset slot, the position of the limiting rod 145 can be changed. Alternatively, if the fixed base 144 is provided with a sliding groove structure, one end of the limiting rod 145 can slide into the sliding groove structure. By sliding the limiting rod 145 within the sliding groove structure, the position of the limiting rod 145 can be changed. Of course, the movable connection method between the limiting rod 145 and the fixed base 144 can also be set according to the reserved space of the flipping mechanism 100, the molding process, etc., and is not limited here.

[0046] In one embodiment, see Figures 1-4 As shown, the first rotating assembly 141 includes a first connecting plate 1411, and the second rotating assembly 142 includes a second connecting plate 1421. Both the first connecting plate 1411 and the second connecting plate 1421 are rotatably mounted on the fixed base 144. The first connecting plate 1411 and the second connecting plate 1421 mesh with each other, and both the first connecting plate 1411 and the second connecting plate 1421 can rotate relative to the fixed base 144. The first connecting plate 1411 is provided with a first connecting portion 1412 connecting the first rotating plate 110, and the second connecting plate 1421 is provided with a second connecting portion 1422 connecting the second rotating plate 120. Both the first connecting portion 1412 and the second connecting portion 1422 are provided with a rotating shaft, which enables the connection between the first connecting plate 1411 and the first rotating plate 110, and the connection between the second connecting plate 1421 and the second rotating plate 120.

[0047] Because the first connecting plate 1411 and the second connecting plate 1421 are meshed with each other, during the rotation of the first connecting plate 1411 with the first rotating plate 110 relative to the base 130, the second connecting plate 1421 with the second rotating plate 120 rotates synchronously, or during the rotation of the second connecting plate 1421 with the second rotating plate 120 relative to the base 130, the first connecting plate 1411 with the first rotating plate 110 rotates synchronously. That is to say, through the meshing of the first connecting plate 1411 and the second connecting plate 1421, the first rotating plate 110 and the second rotating plate 120 can rotate synchronously in directions that move closer to or further away from each other.

[0048] Specifically, see Figures 1-4 As shown, the first connecting plate 1411 has a first gear portion 1413 on the side near the second connecting plate 1421, and the second connecting plate 1421 has a second gear portion 1423 on the side near the second connecting plate 1421. The first gear portion 1413 meshes with the second gear portion 1423. Thus, through the mutual meshing of the first gear portion 1413 and the second gear portion 1423, the first connecting plate 1411 and the second connecting plate 1421 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.

[0049] In one embodiment, see Figures 1-4 As shown, the flipping mechanism 100 also includes a first carrier plate 150 and a second carrier plate 160. The first carrier plate 150 is connected to the first connecting plate 1411 and has a first bearing area 151 for bearing the product to be flipped. The second carrier plate 160 is connected to the second connecting plate 1421 and has a second bearing area 161 for bearing the product to be flipped. When the first carrier plate 150 is connected to the first connecting plate 1411, the first carrier plate 150 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 150. Similarly, when the second carrier plate 160 is connected to the second connecting plate 1421, the second carrier plate 160 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 160.

[0050] During the rotation of the aforementioned flipping mechanism 100, the first connecting plate 1411 and the second connecting plate 1421 can drive the first carrier plate 150 and the second carrier plate 160 to rotate synchronously in a direction that moves closer to or further away from each other, so that the product to be rotated rotates along a preset path, thereby realizing the flipping and folding operation of the product to be rotated.

[0051] Further, see Figures 1-4 As shown, the first rotating plate 110 and the first carrier plate 150 are provided with a first adhesive portion 152 for fixing the product to be rotated, such as the first adhesive portion 152 being formed in the first rotating plate 110 and the first bearing area 151. The second rotating plate 120 and the second carrier plate 160 are provided with a second adhesive portion 162 for fixing the product to be rotated, such as the second adhesive portion 162 being formed in the second rotating plate 120 and the second bearing area 161. In this way, the product to be rotated is glued and fixed to the first rotating plate 110 and the first carrier plate 150 by the first adhesive portion 152, and the product to be rotated is glued and fixed to the second rotating plate 120 and the second carrier plate 160 by the second adhesive portion 162, so as to ensure that the relative position between the product to be rotated and the first rotating plate 110, the first carrier plate 150, the second rotating plate 120, and the second carrier plate 160 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.

[0052] The first adhesive portion 152 and the second adhesive portion 162 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 152 and the second adhesive portion 162. Furthermore, compared to the conventional method where the first adhesive portion 152 and the second adhesive portion 162 are only provided at the positions of the first carrier plate 150 and the second carrier plate 160 respectively, this embodiment provides the first adhesive portion 152 and the second adhesive portion 162 simultaneously at the positions of the first rotating plate 110 and the second rotating plate 120, to ensure that the product to be rotated will not experience misalignment due to relative displacement during rotation.

[0053] In one embodiment, see Figures 1-4 As shown, the first carrier plate 150 is provided with a first limiting boss 153. Preferably, the first limiting boss 153 is integrally formed on the first carrier plate 150 by injection molding, extrusion or other methods, and the first limiting boss 153 protrudes from the surface of the first carrier plate 150 facing the second carrier plate 160 during rotation. The second carrier plate 160 is provided with a second limiting boss 163. Preferably, the second limiting boss 163 is integrally formed on the second carrier plate 160 by injection molding, extrusion or other methods, and the second limiting boss 163 protrudes from the surface of the second carrier plate 160 facing the first carrier plate 150 during rotation.

[0054] When the first carrier plate 150 and the second carrier plate 160 move toward each other, such as when the first carrier plate 150 and the second carrier plate 160 move from... Figure 6 State Orientation Figure 7 In the state of motion, the first limiting boss 153 can abut against the second limiting boss 163. Since the first limiting boss 153 protrudes from the first carrier plate 150 and the second limiting boss 163 protrudes from the second carrier plate 160, the first limiting boss 153 abuts against the second limiting boss 163, preventing the first carrier plate 150 and the second carrier plate 160 from being completely attached together, so as to meet the predetermined testing requirements.

[0055] In one embodiment, see Figures 1-4As shown, the first rotating plate 110 has a first rotating part 112 at each of its opposite ends. The first rotating part 112 is connected to the first connecting part 1412. The first rotating part 112 is rotatably connected to the first connecting part 1412 via a rotating shaft to achieve the connection between the first rotating assembly 141 and the first rotating plate 110. The size of the first rotating part 112 is smaller than the size of the first connecting part 1412. For example, the first rotating part 112 is formed by subtractive manufacturing, such as chamfering, drilling, or surface cutting, to reduce the overall size of the first rotating part 112, making its size smaller than that of the first connecting part 1412. Thus, by making the first rotating part 112 smaller, a clearance space is formed between the first rotating part 112 and the first connecting part 1412. During the rotation of the first carrier plate 150, interference from the first rotating part 112 is avoided, ensuring the smoothness of the first carrier plate 150's rotation.

[0056] Similarly, each end of the second rotating plate 120 is provided with a second rotating part 122, which is connected to the second connecting part 1422. The second rotating part 122 is rotatably connected to the second connecting part 1422 via a rotating shaft to achieve connection between the second rotating assembly 142 and the second rotating plate 120. The size of the second rotating part 122 is smaller than the size of the second connecting part 1422. By making the second rotating part 122 smaller, a clearance space is formed between the second rotating part 122 and the second connecting part 1422. During the rotation of the second carrier plate 160, interference from the second rotating part 122 is avoided, ensuring smooth rotation of the second carrier plate 160.

[0057] In one embodiment, see Figures 1-4 As shown, there are multiple limiting components 143, with at least two limiting components 143 disposed at opposite ends of the base 130. For example, there may be two limiting components 143, each disposed on one of the two flip modules 140; or there may be three limiting components 143, spaced apart along the extension direction of the base 130, with two limiting components 143 disposed on each of the two flip modules 140. This application does not limit the number of limiting components 143; it can be specifically set according to rotation requirements.

[0058] Thus, by providing limit components 143 at both opposite ends of the base 130, the guiding stability and reliability of the first rotating plate 110 and the second rotating plate 120 during rotation can be guaranteed.

[0059] Additionally, see Figures 1-4As shown, this application also provides a testing device, which includes a testing fixture and a flipping mechanism 100 as described in any of the above technical solutions. The flipping mechanism 100 is detachably connected to the testing fixture. For example, both the first carrier plate 150 and the second carrier plate 160 are provided with bushings 170. After the first carrier plate 150 and the second carrier plate 160 are rotated to a preset angle, the bushings 170 position the connection between the first carrier plate 150, the second carrier plate 160 and the testing fixture. Then, the flipping mechanism 100 is connected to the testing fixture by means of screws, snaps, etc., and the product to be rotated carried by the flipping mechanism 100 is tested through the testing fixture.

[0060] In the aforementioned testing device, the limiting component 143 is used to limit the rotation trajectory of the first rotating plate 110 and / or the second rotating plate 120, so that the rotation trajectory of the first rotating plate 110 and / or the second rotating plate 120 is unique. The flipping mechanism 100 moves according to the predetermined rotation path during the flipping process, thereby improving the smoothness of the product to be flipped during the rotation process, and thus improving the flipping efficiency and user experience of the product to be flipped.

[0061] 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.

[0062] 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.
