Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of testing electronic devices, and in particular to a foldable device opening and closing testing device. Background Art

[0002] With the gradual development of flexible screen technology, foldable electronic devices have emerged. Foldable electronic devices have become a hot technology today due to their larger display area and good portability. In the process of using foldable electronic devices, folding the foldable electronic devices can facilitate the carrying of the electronic devices. By unfolding the foldable electronic devices, the large-screen display function of the electronic devices can be realized.

[0003] In order to manufacture foldable electronic devices that can meet the needs of users, before the foldable electronic devices leave the factory, it is usually necessary to simulate user use to conduct torque, abnormal noise, bending aging and other tests, that is, to repeatedly fold and unfold (that is, open and close) the foldable electronic devices.

[0004] In the related art, the opening and closing test of foldable electronic devices usually adopts a test scheme in which one side is fixed and the other side is opened and closed. The opening and closing test of the foldable electronic device is achieved by fixing one side of the foldable electronic device and using a clamp to clamp the other side of the foldable electronic device and rotate it. However, the rotation axis of the foldable electronic device will change during the unfolding and folding process, which will cause the side of the foldable electronic device that is fixed and the side that is clamped by the clamp to be misaligned during the opening and closing test, thereby damaging the foldable electronic device. Summary of the invention

[0005] The embodiment of the present application provides a foldable device opening and closing test device, which can avoid the problem of the foldable device being damaged due to the eccentricity between the opening and closing test device and the foldable device during the opening and closing test.

[0006] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0007] The embodiment of the present application provides a foldable device opening and closing test device, which is used to perform an opening and closing test on the foldable device, wherein the foldable device includes N rotating parts, and the N rotating parts can rotate relative to each other so that the foldable device can switch between an unfolded state and a folded state. The foldable device opening and closing test device includes: N folding mechanisms, wherein the N folding mechanisms are arranged in sequence along a first direction, wherein N is a positive integer greater than or equal to 2;

[0008] The folding mechanism includes a clamping portion, which is used to fix one of the rotating parts of the foldable device. Each of the clamping portions can drive the corresponding rotating part to rotate. The rotation axis of each of the clamping portions is perpendicular to the first direction, and the rotation directions of two adjacent clamping portions are opposite.

[0009] The foldable device opening and closing test device provided by the embodiment of the present application has a clamping part for clamping the foldable device. When the foldable electronic device is assembled on the clamping part, the rotation directions of the clamping parts of the two adjacent folding mechanisms are opposite, and the clamping parts rotate in a plane perpendicular to the first direction on one side and translate in a plane perpendicular to the first direction on the other side. In this way, the opening and closing test of the foldable electronic device can be completed. Since the clamping parts of each folding mechanism have their own rotation axis, during the unfolding and folding process of the foldable electronic device, the rotation axis of the clamping part of each folding mechanism can maintain a fixed distance from the corresponding rotation axis of the foldable electronic device, thereby adapting to the situation that the rotation axis of the foldable electronic device changes during the unfolding and folding process, and preventing the foldable electronic device from being damaged due to the misalignment of two adjacent rotating parts during the opening and closing test. In addition, the foldable device opening and closing test device provided by the embodiment of the present application has no additional adjustment mechanism, has a small load on the foldable electronic device, and has low requirements on the driving force. At the same time, the foldable device opening and closing test device provided by the embodiment of the present application has a simple structure and is easy to operate, which is conducive to the opening and closing test.

[0010] In a possible embodiment, the folding mechanism further includes a rotating rod, one end of which is fixedly connected to the clamping portion, the end of which is connected to the clamping portion is rotatably arranged, and the rotation axis of the end of which is connected to the clamping portion is perpendicular to the first direction.

[0011] The rotating rod can be used as a connecting component between the clamping part and the power source, which is beneficial to the structural arrangement of the foldable equipment opening and closing test device.

[0012] In a possible embodiment, the folding mechanism further includes a connecting rod and a linkage rod, wherein one end of the rotating rod away from the clamping portion is rotatably connected to the connecting rod, an extension direction of the linkage rod is parallel to a line connecting the first end of the folding mechanism and the second end of the folding mechanism, and both ends of the linkage rod are respectively connected to the connecting rods of two adjacent folding mechanisms.

[0013] The rotation axis of the rotating rod and the connecting rod can be used as a reference for aligning the corresponding rotation axis of the foldable electronic device, and the linkage rod can synchronize the two adjacent folding mechanisms when flipping, thereby preventing the foldable device from being damaged due to the asynchronous flipping of the two adjacent folding mechanisms. In addition, the number of first driving devices can be reduced, thereby reducing manufacturing costs.

[0014] In a possible implementation manner, the foldable electronic device further includes: a first driving device, wherein the first driving device is connected to the connecting rod.

[0015] In a possible implementation, the foldable electronic device further includes: two first fixed slide bars, the two first fixed slide bars are arranged in parallel, the first end of the folding mechanism and the second end of the folding mechanism are respectively connected to the two first fixed slide bars, and at least N-1 of the folding mechanisms are slidably arranged in the length direction of the first fixed slide bars.

[0016] In a possible implementation, the N folding mechanisms are all slidably arranged in the length direction of the first fixed slide bar. The N folding mechanisms can slide relative to the N-1 folding mechanisms, which can improve the continuity of the folding mechanisms when they move, and is conducive to the opening and closing test.

[0017] In a possible implementation, the foldable device opening and closing test device further includes: a first sliding block;

[0018] At least one first sliding block is slidably disposed on each of the first fixed sliding bars, and the first end of the folding mechanism and the second end of the folding mechanism are rotatably connected to the corresponding first sliding block, so that the folding mechanism can slide on the first fixed sliding bar.

[0019] In a possible implementation, the clamping portion includes: two clamping seats, the two clamping seats are arranged opposite to each other in the direction of a line connecting the first end of the folding mechanism and the second end of the folding mechanism, and the clamping seats are used to fix the foldable device.

[0020] In a possible implementation manner, the clamping portion further includes: a bearing seat, the two clamping seats are both arranged on the bearing seat, and the two ends of the bearing seat are respectively rotatably connected to the corresponding first sliding blocks on the two first fixed sliding rods.

[0021] The function of the bearing seat is to enable the two clamping seats located on the bearing seat to rotate synchronously, so as to prevent the clamping seats from generating torque on the foldable device and causing damage to the foldable device.

[0022] In a possible embodiment, a strip groove is provided on the clamping seat, and the strip groove is used to fix the folding device. The orthographic projection area of ​​the strip groove on the rotating rod along the second direction intersects with the rotation axis of the rotating rod around the connecting rod, or, the extended area of ​​the orthographic projection area of ​​the strip groove on the rotating rod along the second direction intersects with the rotation axis of the rotating rod around the connecting rod, and the second direction is parallel to the line connecting the first end of the folding mechanism and the second end of the folding mechanism.

[0023] The two folding mechanisms are placed horizontally, and the foldable electronic device is assembled into the bar groove from one side of the folding mechanism. In this way, the foldable electronic device can be easily placed. In addition, since the orthogonal projection area of ​​the bar groove on the rotating rod intersects with the rotation axis of the rotating rod around the connecting rod, or the extended area of ​​the orthogonal projection area of ​​the bar groove on the rotating rod intersects with the rotation axis of the rotating rod around the connecting rod, when the foldable electronic device is assembled into the bar groove, the centering operation of the foldable electronic device and the rotating rod around the rotation axis of the connecting rod can be reduced, which is conducive to the rapid opening and closing test.

[0024] In a possible implementation manner, the clamping seat has a bearing step, the bearing step is located on a side of the strip-shaped groove close to the bearing seat, and the bearing step is used to place the foldable device.

[0025] In a possible implementation, the foldable device opening and closing test device further includes: a stopper, wherein the stopper is disposed on the folding mechanism at the end of the N folding mechanisms, and the stopper is disposed on a side of the folding mechanism away from the other folding mechanisms.

[0026] When the foldable electronic device is assembled into the strip groove and pushed to the stopper, the axis of a main body of the foldable electronic device can be aligned or approximately aligned with the rotation axis of the rotating rod around the connecting rod, which can reduce the centering operation of the foldable electronic device and the rotation axis of the rotating rod around the connecting rod, and is conducive to the rapid opening and closing test.

[0027] In a possible implementation, the stopper is telescopically disposed on one side of the support seat, and the telescopic direction of the stopper is parallel to the extending direction of the strip groove. In this way, the foldable device opening and closing test device can be used for foldable electronic devices of different specifications.

[0028] In a possible implementation, both ends of the linkage rod are rotatably connected to the connecting rods of two adjacent folding mechanisms, so that the foldable device opening and closing test device can be applied to foldable devices with different axis center distances.

[0029] In a possible implementation, a first bearing hole is formed on the connecting rod, a first bearing is built in the first bearing hole, a first connecting shaft is fixed on the linkage rod, and the first bearing is sleeved on the first connecting shaft. In this way, the friction force when the connecting rod rotates around the linkage rod can be reduced, and the opening and closing test device can be prevented from getting stuck.

[0031] When the first driving device drives the linkage rod, the connecting rod or the first sliding block to move, the linkage rod can only move along the extension direction of the second fixed sliding bar, in accordance with the linkage method in the folding device opening and closing test device provided in the embodiment of the present application. In this way, the stability of the folding device opening and closing test device during operation can be enhanced.

[0032] In a possible implementation, the first driving device is a telescopic driving device, the output shaft of the first driving device is connected to the second sliding block, and the extension direction of the output shaft is parallel to the extension direction of the second fixed sliding bar. The telescopic driving device can drive the linkage rod to perform repeated movements in only one direction, which conforms to the linkage mode in the foldable device opening and closing test device provided in the embodiment of the present application, and can enhance the stability of the foldable device opening and closing test device during operation.

[0033] In a possible implementation, the foldable device opening and closing test device further includes: a fixing seat and two supporting frames disposed on the fixing seat and opposite to each other, and the two first fixed sliding rods are respectively fixed to the two supporting frames.

[0034] The support frame and the fixing seat are the skeleton of the folding equipment opening and closing test device, so that the opening and closing test device becomes a whole, which is beneficial to the stability of the folding equipment opening and closing test device during operation.

[0035] In a possible implementation manner, the second fixed sliding bars are all fixed on the corresponding supporting frames.

[0036] In a possible implementation, the foldable device opening and closing test device further includes: a second driving device, and the second driving device is used to drive the folding mechanism to slide in the length direction of the first fixed sliding rod.

[0037] The second driving device can cooperate with the first driving device or replace the first driving device as the power source of the foldable device opening and closing test device. Alternatively, the second driving device can be used for centering operation.

[0080] The terms used in the implementation method part of this application are only used to explain the specific embodiments of this application, and are not intended to limit this application. The implementation method of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0081] The test target of the foldable device opening and closing test device provided in the embodiment of the present application can be an electronic device or a non-electronic device. In the embodiment of the present application, the foldable device is taken as an example to be explained, and the following are all foldable electronic devices.

[0082] A foldable electronic device is a type of electronic device with a foldable screen. A foldable electronic device can change the unfolded or folded state of the foldable screen and itself. Under different usage requirements, the foldable electronic device can be unfolded to an unfolded state or folded to a folded state. Foldable electronic devices can be, for example, terminal products such as mobile phones, tablet computers (pads), televisions, smart wearable products (such as smart watches, smart bracelets, etc.), virtual reality (VR) devices, augmented reality (AR) devices, and can also be professional shooting equipment such as digital cameras, SLR cameras, micro single cameras, sports cameras, etc. For the convenience of explanation, the foldable electronic device is described as a foldable mobile phone in the embodiment of the present application.

[0083] Figure 1 is a schematic diagram of a foldable electronic device 10 in a flattened state, referring to Figure 1 As shown, under normal circumstances, the foldable electronic device 10 generally includes: a folding screen 11, a first main body 12, a second main body 13 and a rotating part 14. The first main body 12 and the second main body 13 are respectively connected to the two sides of the rotating part 14, and the rotating part 14 is used to enable the first main body 12 and the second main body 13 to be relatively unfolded and folded, wherein the structures of the first main body 12 and the second main body 13 may be the same, may not be completely the same, or may be completely different. It is understandable that in addition to using one rotating part 14 and two main bodies to form a two-layer folding structure, the foldable electronic device 10 may also use multiple rotating parts 14 and more than two main bodies to form a folding structure with more layers. In the example of this application, two main bodies are used as an example for explanation.

[0084] The folding screen 11 is attached to a surface where the first main body 12 and the second main body 13 are close to each other or away from each other when they are folded. Figure 1As shown in the figure, from the user's observation angle, when the foldable electronic device 10 is in a flattened state, the user faces the foldable screen 11, and the foldable screen 11 is attached to the upper surfaces of the first body part 12 and the second body part 13. During the process of relative unfolding and folding of the first body part 12 and the second body part 13, the foldable screen 11 is unfolded and folded simultaneously with the first body part 12 and the second body part 13.

[0085] like Figure 1 As shown in , the foldable electronic device 10 can be unfolded to a flat state; Figure 2 As shown in Figure 2 It is a schematic diagram of the folded structure of a foldable electronic device 10. The foldable electronic device 10 can also be folded to a folded state. Of course, the foldable electronic device 10 can also be unfolded or folded to an intermediate state, and the intermediate state can be any state between the flattened state and the folded state. The foldable screen 11 is a bendable structure. The foldable screen 11 moves with the first main body 12 and the second main body 13. The first main body 12 and the second main body 13 can drive the foldable screen 11 to unfold or fold, so that the foldable electronic device 10 can be unfolded or folded to a flattened state, a folded state or an intermediate state.

[0086] When the foldable electronic device 10 is in the folded state, the foldable screen 11 is located inside the first main body 12 and the second main body 13, and the foldable electronic device 10 is an inner-screen foldable device; when the foldable electronic device 10 is in the folded state, the foldable screen 11 is located outside the first main body 12 and the second main body 13, and the foldable electronic device 10 is an outer-screen foldable device. Figure 1 and Figure 2 The foldable electronic device 10 shown in the figure is a screen-outward foldable device.

[0087] Figure 3 is a schematic diagram of a folding screen 11 in a foldable electronic device 10, referring to Figure 3 As shown, the folding screen 11 generally includes: a folding display portion 11c and a first display portion 11a and a second display portion 11b respectively located on both sides of the folding display portion 11c. During the use of the folding electronic device 10, the first display portion 11a and the second display portion 11b generally do not deform, and the folding display portion 11c deforms so that the folding screen 11 can be relatively unfolded and folded. For example, when the folding electronic device 10 is completely folded, the folding display portion 11c can be deformed into a water drop shape.

[0088] It should be noted that Figure 3The middle dotted line is only used to distinguish the first display portion 11a, the second display portion 11b and the folding display portion 11c, and does not indicate a structural line. The folding screen 11 is still a complete screen. In addition, the length and width of the first display portion 11a and the second display portion 11b can be the same, not completely the same, or completely different.

[0089] Since the foldable electronic device 10 can be switched between the flattened state and the folded state, when the user uses the foldable electronic device 10 to browse web pages, information, videos, play games, etc., the foldable electronic device 10 can be switched from the folded state to the unfolded state, which can achieve a large screen display, provide the user with richer information, and bring the user a better user experience. When the user has finished using the foldable electronic device 10, the foldable electronic device 10 can be switched from the flattened state to the folded state. In this way, the volume of the foldable electronic device 10 can be reduced, making it easier to store the foldable electronic device 10.

[0090] It can be seen that when the user uses the foldable electronic device 10, the foldable electronic device 10 needs to be frequently driven to switch between the flat state and the folded state. In order to manufacture a foldable electronic device 10 that can meet the user's needs and ensure the consistency of the user's experience, before the foldable electronic device 10 leaves the factory, it is usually necessary to simulate user use to perform torque, abnormal noise, bending aging and other tests, that is, repeatedly fold and unfold (that is, open and close) the foldable electronic device 10.

[0091] At present, the foldable electronic device 10 is usually folded and unfolded by rotating with two rotating axes, which can be understood as the foldable electronic device having two rotating axes. Figure 4 , Figure 4 The figure is a schematic diagram of the connection between the first main body 12, the second main body 13 and the rotating part 14 in a foldable electronic device 10. The rotating part 14 generally includes: a bracket 14a and swing arms 14b located on both sides of the bracket 14a. One end of the swing arm 14b on one side of the bracket 14a is connected to the first main body 12, and the other end is rotatably connected to the bracket 14a, so that the first main body 12 can rotate around the axis A. One end of the swing arm 14b on the other side of the bracket 14a is connected to the second main body 13, and the other end is rotatably connected to the bracket 14a, so that the second main body 13 can rotate around the axis B. When the foldable electronic device 10 is folded and unfolded, the first main body 12 rotates around the axis A, and the second main body 13 rotates around the axis B.

[0092] In the related art, the opening and closing test of the foldable electronic device 10 usually adopts a test scheme in which one side is fixed and the other side is opened and closed. Figure 5 , Figure 5It is a schematic diagram of an opening and closing test of a foldable electronic device 10 in a related art. In the related art, the first main body 12 is usually fixed, and the second main body 13 is clamped by a clamp 20 for opening and closing. Based on the above description, the opening and closing movement of the second main body 13 is not a fixed-axis rotation, but a superposition of the movement of the double-axis (axis A and axis B) rotation. The clamp 20 is generally fixedly connected to the output shaft of the motor through a connector, and is a fixed-axis rotation. This means that the foldable electronic device 10 cannot ensure that the rotation center of the clamp 20 is always consistent with the rotation center of the foldable electronic device 10 during the opening and closing test. During the opening and closing test, the test system will be stuck with the foldable electronic device 10. If the clamp 20 continues to drive the foldable electronic device 10 to rotate, the foldable electronic device 10 will be at risk of being damaged.

[0093] There are two main solutions in the related art to the above problems. The first solution is to increase the degree of freedom on the transmission side to adapt to the dual-axis rotation of the foldable electronic device 10, that is, to increase the degree of freedom between the output shaft of the motor and the fixture 20. For example, a slide groove is provided on the connecting member connected to the output shaft of the motor and the fixture 20, and the fixture 20 is slidably set in the slide groove. When the opening and closing test is carried out, the fixture 20 drives the second main body 13 to rotate and can slide in the slide groove to adapt to the dual-axis rotation of the foldable electronic device 10, thereby preventing the foldable electronic device 10 from being damaged. However, under this solution, the connection between the connecting member connected to the motor and the fixture 20 is not fixed. During the opening and closing test, relative displacement will occur between the connecting member and the fixture 20, resulting in insufficient transmission accuracy, thereby affecting the accuracy of the opening and closing test results.

[0094] The second solution is to increase the degree of freedom on the side of the fixture 20 to adapt to the dual-axis rotation of the foldable electronic device 10, that is, to increase the degree of freedom between the fixture 20 and the foldable electronic device 10. For example, an adjustment mechanism is added to the fixture 20. When the opening and closing test is carried out, the fixture 20 drives the second main body 13 to rotate, and the adjustment mechanism can cause the fixture 20 to produce a certain displacement relative to the foldable electronic device 10, so as to adapt to the dual-axis rotation of the foldable electronic device 10, thereby preventing the foldable electronic device 10 from being damaged. However, under this solution, the structural design of the adjustment mechanism is complicated. In addition, due to the addition of an additional adjustment mechanism, the weight of the fixture 20 will increase, and higher requirements will be placed on the power source. In addition, the added adjustment mechanism will rotate with the foldable electronic device 10, which increases the motion load for the foldable electronic device 10, which will cause the mechanical properties of the foldable electronic device 10 to change when it rotates, thereby affecting the accuracy of the opening and closing test results.

[0095] The above scheme has problems such as low opening and closing test accuracy and high system complexity of the opening and closing test device, and it is difficult to meet the requirements of high-precision opening and closing test of the foldable electronic device 10 and the simplification of the opening and closing test device. In view of this, the embodiment of the present application provides a foldable device opening and closing test device 100, which performs an opening and closing test on the foldable electronic device 10 without adding additional degrees of freedom or additional adjustment mechanisms, has high transmission accuracy, does not increase the motion load on the foldable electronic device 10, meets the requirements of high-precision opening and closing test of the foldable electronic device 10, and can be used for the dual-axis rotation of the foldable electronic device 10, thereby preventing the foldable electronic device 10 from being damaged. In addition, the foldable device opening and closing test device 100 has a simple structure and is easy to operate.

[0096] The foldable device opening and closing test device 100 provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0097] Figure 6 A schematic diagram of a foldable electronic device 10 placed in a foldable device opening and closing test device 100 provided in an embodiment of the present application, with reference to Figure 6 As shown, the foldable electronic device 10 is in a flattened state and is placed on a foldable device opening and closing test device 100. For the convenience of description, a three-dimensional rectangular coordinate system is established, and the definition is Figure 6 In the figure, the width direction of the foldable electronic device 10 when in a flattened state is the X-axis direction, the length direction is the Y-axis direction, and the thickness direction is the Z-axis direction. The X-axis direction, the Y-axis direction, and the Z-axis direction are perpendicular to each other. Exemplarily, the extension direction of the rotation axis of the foldable electronic device 10 is parallel to the Y-axis direction. That is, the foldable electronic device 10 can be relatively unfolded or relatively folded around the Y-axis direction. In addition, the following figures all use this three-dimensional rectangular coordinate system.

[0098] It should be noted that the qualifiers about relative positional relationship such as parallel and perpendicular mentioned in the embodiments of the present application are all for the current state of the art, rather than strict definitions specified in a mathematical sense, and a small amount of deviation is allowed, and both approximately parallel and approximately perpendicular are acceptable. For example, A is parallel to B, which means that A and B are parallel or approximately parallel, and the angle between A and B can be between 0 degrees and 10 degrees. For example, A is perpendicular to B, which means that A and B are perpendicular or approximately perpendicular, and the angle between A and B can be between 80 degrees and 100 degrees.

[0099] Figure 7 for Figure 6 The structural diagram of the foldable device opening and closing test device 100 provided in Figure 7 Combined with Figure 6As shown, the foldable device opening and closing test device 100 provided in the embodiment of the present application may include: two first fixed sliding bars 110, N folding mechanisms 120 (N is a positive integer greater than or equal to 2) and a first driving device ( Figure 7 not shown).

[0100] Specifically, the two first fixed sliding bars 110 are arranged parallel and opposite to each other, such as Figure 7 In the embodiment, the two first fixed slide bars 110 are arranged parallel to the X axis. In practical application, the first fixed slide bars 110 are fixed components, for example, the first fixed slide bars 110 can be fixed on a base to ensure the stability of the entire opening and closing test device.

[0101] N folding mechanisms 120 correspond to N folding types of folding electronic devices 10. For example, two folding mechanisms 120 can perform an opening and closing test on a two-folding folding electronic device 10, three folding mechanisms 120 can perform an opening and closing test on a three-folding folding electronic device 10, four folding mechanisms 120 can test a four-folding folding electronic device 10, and so on. Exemplarily, in the embodiment of the present application, N is 2 as an example for detailed description, that is, the opening and closing test of the two-folding folding electronic device 10 is described.

[0102] The folding mechanism 120 has a first end and a second end away from the first end. The first end and the second end of the folding mechanism 120 are respectively connected to the two first fixed slide bars 110. It can be understood that the folding mechanism 120 extends along the Y-axis direction, and the first end and the second end of the folding mechanism 120 are both connected to the first fixed slide bars 110. N folding mechanisms 120 are arranged in sequence along the first direction. For example, the N folding mechanisms 120 are arranged in sequence in the length direction of the first fixed slide bar 110. It can be understood that the N folding mechanisms 120 are arranged in sequence in the X-axis direction. Among them, the line connecting the first end and the second end of the folding mechanism 120 is perpendicular to the X direction, that is, the line connecting the first end and the second end of the folding mechanism 120 is perpendicular to the plane formed by the X-axis and the Z-axis.

[0103] The folding mechanism 120 includes: a clamping portion 121, a rotating rod 1221 and a connecting rod 1222. The clamping portion 121 is used to fix the foldable device, for example, Figure 6 In the embodiment, one of the two clamping portions 121 fixes the first main body portion 12 of the foldable electronic device 10 , and the other clamping portion 121 fixes the second main body portion 13 of the foldable electronic device 10 .

[0104] Among them, one end of the rotating rod 1221 is fixedly connected to the clamping part 121, and the other end of the rotating rod 1221 is rotatably connected to the connecting rod 1222. For example, a third bearing hole 123c can be opened on the connecting rod 1222, and a second bearing hole 123b can be opened on the rotating rod 1221, and a second bearing 140b is built in the second bearing hole 123b, and a third bearing 140c is built in the third bearing hole 123c, and the third bearing 140c on the connecting rod 1222 and the second bearing 140b on the rotating rod 1221 are connected by the second connecting shaft 124b, so that the rotating rod 1221 is rotatably connected to the connecting rod 1222. In this way, the friction force when the rotating rod 1221 and the connecting rod 1222 rotate can be reduced, and the situation where the opening and closing test device is stuck can be prevented.

[0105] Among them, the rotating rod 1221 is rotatably arranged relative to the first fixed sliding rod 110, and the plane where the trajectory formed by the rotating rod 1221 rotating relative to the first fixed sliding rod 110 lies is perpendicular to the vertical line connecting the two first fixed sliding rods 110, that is, the rotating rod 1221 rotates relative to the first fixed sliding rod 110 in a plane, and the plane is parallel to the plane formed by the X-axis and the Z-axis.

[0106] Since the clamping portion 121 is fixedly connected to the rotating rod 1221, the rotating rod 1221 of each folding mechanism 120 has its own rotation axis, that is, the clamping portion 121 of each folding mechanism 120 has its own rotation axis, and the rotation axis of the clamping portion 121 of each folding mechanism 120 is perpendicular to the first direction, that is, perpendicular to the plane formed by the X-axis and the Z-axis.

[0107] The first driving device is used to drive the connecting rod 1222 to drive the rotating rod 1221 to rotate relative to the first fixed slide bar 110. Since the rotating rod 1221 is fixedly connected to the clamping portion 121, when the first driving device drives the connecting rod 1222 to drive the rotating rod 1221 to rotate relative to the first fixed slide bar 110, the clamping portion 121 will also rotate relative to the first fixed slide bar 110 along with the rotating rod 1221, and the plane where the trajectory formed by the rotation of any point on the clamping portion 121 relative to the first fixed slide bar 110 is located is also perpendicular to the vertical line connecting the two first fixed slide bars 110, that is, any point on the clamping portion 121 rotates relative to the first fixed slide bar 110 in a plane parallel to the plane formed by the X-axis and the Z-axis.

[0108] The rotation axis of the rotating rod 1221 around the connecting rod 1222 is used to align with the corresponding rotation axis of the foldable electronic device 10 (hereinafter referred to as centering). Figure 6 Combined with Figure 4 and Figure 7As shown, based on the above description, the two-fold foldable electronic device 10 has an axis A and an axis B. When the two-fold foldable electronic device 10 is placed in the foldable device opening and closing test device 100 provided in the embodiment of the present application, the rotation axis of the rotating rod 1221 of one of the folding mechanisms 120 around the connecting rod 1222 is aligned with the axis A of the foldable electronic device 10, and the rotation axis of the rotating rod 1221 of the other folding mechanism 120 around the connecting rod 1222 is aligned with the axis B of the foldable electronic device 10. It should be noted that, here, "the rotation axis of the rotating rod 1221 around the connecting rod 1222 is used to align with the corresponding rotation axis of the foldable electronic device 10" refers to the tolerance range, and does not mean that the rotation axis is strictly aligned with the rotation axis. A small amount of deviation is allowed, and both alignment and approximate alignment are acceptable. For example, the rotation axis of the rotating rod 1221 around the connecting rod 1222 is aligned with the corresponding rotation axis of the foldable electronic device 10, which means that the rotation axis of the rotating rod 1221 around the connecting rod 1222 is strictly aligned or approximately aligned with the corresponding rotation axis of the foldable electronic device 10. When approximately aligned, the distance deviation between the rotation axis of the rotating rod 1221 around the connecting rod 1222 and the corresponding rotation axis of the foldable electronic device 10 can be between 0-1mm.

[0109] Figure 8 Schematic diagram of a state in an opening and closing test of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 1 , Figure 8 Can be considered as Figure 6 The middle connecting rod 1222 moves toward the negative direction of the Z axis and drives the rotating rod 1221 and the clamping part 121 to rotate. Fig. 9 Schematic diagram of a state in an opening and closing test of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 2 , Fig. 9 Can be considered as Figure 6 or Figure 8 The middle connecting rod 1222 moves in the positive direction of the Z axis and drives the rotating rod 1221 and the clamping part 121 to rotate. Figure 8 and Fig. 9 Combined with Figure 6As shown, in the opening and closing test, when the foldable electronic device 10 is driven from the flat state to the folded state, two adjacent folding mechanisms 120 need to be close to each other. On the contrary, when the foldable electronic device 10 is driven from the folded state to the flat state, two adjacent folding mechanisms 120 need to be far away. Based on this, in the foldable device opening and closing test device 100 provided in the embodiment of the present application, N folding mechanisms 120 can be arranged to translate in a plane perpendicular to the line connecting the first end and the second end of the folding mechanism 120. For example, in the drawings of the embodiment of the present application, the N folding mechanisms 120 can slide in the length direction of the first fixed slide bar 110.

[0110] For example, Figure 6 , Figure 8 and Fig. 9 As shown in , both ends of the two folding mechanisms 120 are slidably disposed on the first fixed slide bar 110. It is understandable that, among the N folding mechanisms 120, only N-1 folding mechanisms 120 may be slidably disposed on the first fixed slide bar 110, that is, one folding mechanism 120 is fixedly connected to the first fixed slide bar 110, and N-1 folding mechanisms 120 are slidably connected to the first fixed slide bar 110, and the displacement of the folding mechanism 120 fixedly connected to the first fixed slide bar 110 that originally needs to be moved can be compensated by the N-1 folding mechanisms 120 slidably connected to the first fixed slide bar 110.

[0111] It is easy to understand that the N folding mechanisms 120 can all slide relative to the N-1 folding mechanisms 120 , which can improve the continuity of the folding mechanisms 120 when they move, and is beneficial to the opening and closing test.

[0112] It is understandable that when the foldable electronic device 10 is assembled on the clamping portion 121, the rotation directions of the clamping portions 121 of two adjacent folding mechanisms 120 can be opposite, and the clamping portions 121 can rotate in a plane parallel to the X-axis and the Z-axis, and translate in a plane formed by the Z-axis and the Z-axis, so that the opening and closing test of the foldable electronic device 10 can be completed. Since the clamping portion 121 of each folding mechanism 120 has its own rotation axis, during the unfolding and folding process of the foldable electronic device 10, the rotation axis of the clamping portion 121 of each folding mechanism 120 can maintain a fixed distance from the corresponding rotation axis of the foldable electronic device 10, thereby adapting to the situation that the rotation axis of the foldable electronic device 10 changes during the unfolding and folding process, and preventing the foldable electronic device 10 from being damaged due to the misalignment of the first main body 12 and the second main body 13 during the opening and closing test.

[0113] Since at least N-1 folding mechanisms 120 can slide on the first fixed slide bar 110 in the foldable device opening and closing test device 100 provided in the embodiment of the present application, the distance between the two adjacent folding mechanisms 120 can be adjusted according to the distance between the two adjacent axes of the foldable electronic device, so as to be applicable to the opening and closing test of foldable electronic devices of different specifications. In addition, the foldable device opening and closing test device 100 provided in the embodiment of the present application can also be applicable to the working condition where the two adjacent main bodies rotate on a single axis. For example, in the two-fold foldable electronic device 10, it is assumed that the axis A and the axis B coincide with each other. Since the two adjacent folding mechanisms 120 are independent components, the rotation axis of the rotating rod 1221 of the two adjacent folding mechanisms 120 around the connecting rod 1222 can be aligned with the same axis of the foldable electronic device 10 (the coincident axis of the axis A and the axis B), and they do not interfere with each other, thereby expanding the scope of application of the opening and closing test of foldable electronic devices of different specifications.

[0114] Continue to refer Figure 8 and Fig. 9 Combined with Figure 6 As shown, when the first driving device drives the connecting rod 1222 to drive the rotating rod 1221 to rotate relative to the first fixed sliding rod 110, since the rotating rod 1221 is fixedly connected to the clamping portion 121, and since the rotation axis of the rotating rod 1221 around the connecting rod 1222 is pre-aligned with the corresponding rotation axis of the foldable electronic device 10 when the foldable electronic device 10 is assembled, in the opening and closing test, no matter how the foldable electronic device 10 is opened or closed, the rotation axis of the foldable electronic device 10 and the pre-aligned rotation axis of the rotating rod 1221 around the connecting rod 1222 always remain concentric. For example, Figure 6 , Figure 8 and Fig. 9 In the embodiment, the rotation axis of one of the rotating rods 1221 around the connecting rod 1222 is always kept concentric with the axis A of the foldable electronic device 10, and the rotation axis of the other rotating rod 1221 around the connecting rod 1222 is always kept concentric with the axis B of the foldable electronic device 10. In this way, the problem of the foldable electronic device 10 being damaged due to the non-concentricity between the opening and closing test device and the foldable electronic device 10 can be avoided during the opening and closing test, and the opening and closing test can be completed without risk.

[0115] It can be understood that in the foldable device opening and closing test device 100 provided in the embodiment of the present application, the clamping portion 121 is used to clamp the foldable electronic device 10, one end of the rotating rod 1221 is fixedly connected to the clamping portion 121, and the other end of the rotating rod 1221 is rotatably connected to the connecting rod 1222. The rotating rod 1221 can rotate relative to the first fixed sliding rod 110, and the plane where the trajectory formed by its rotation lies is perpendicular to the vertical line connecting the two first fixed sliding rods 110. That is to say, the clamping portion 121 can rotate with the rotating rod 1221 to drive the foldable electronic device 10 to open and close. Before the opening and closing test, when the foldable electronic device 10 is assembled in the foldable device opening and closing test device 100, the rotation axis of the rotating rod 1221 around the connecting rod 1222 can be aligned with the corresponding rotation axis of the foldable electronic device 10. Since the rotating rod 1221 is fixedly connected to the clamping portion 121, when the first driving device drives the connecting rod 1222 to drive the rotating rod 1221 to rotate relative to the first fixed sliding rod 110, the rotation axis of the rotating rod 1221 around the connecting rod 1222 will always be aligned with the corresponding rotation axis of the foldable electronic device 10, fitting the movement process of the foldable electronic device 10, thereby avoiding the problem of the foldable electronic device 10 being damaged due to the non-concentricity of the opening and closing test device and the foldable electronic device 10 during the opening and closing test.

[0116] Moreover, in the foldable device opening and closing test device 100 provided in the embodiment of the present application, there is no relative displacement between the first drive device and the clamping portion 121 and between the clamping portion 121 and the foldable electronic device, and the transmission is accurate, thereby increasing the accuracy of the opening and closing test of the target object. In addition, the foldable device opening and closing test device 100 provided in the embodiment of the present application has no additional adjustment mechanism, the load on the foldable electronic device 10 is small, and the driving force requirement for the first drive device is low. At the same time, the foldable device opening and closing test device 100 provided in the embodiment of the present application has a simple structure and is easy to operate, which is conducive to the opening and closing test.

[0117] It is easy to understand that the foldable device opening and closing test device 100 provided in the embodiment of the present application can be applied to foldable devices with various opening and closing angles by adjusting the stroke of the first driving device. For example, the foldable electronic devices 10 circulating on the market are generally 180° opening and closing and 360° opening and closing. By adjusting the shorter stroke adapted by the first driving device, the foldable electronic device 10 with 180° opening and closing can be opened and closed. By adjusting the longer stroke adapted by the first driving device, the foldable electronic device 10 with 360° opening and closing can be opened and closed. The first driving device can also be connected to an external electric control system to realize the automation of the entire foldable device opening and closing test device 100.

[0118] Continue to refer Figure 6 , Figure 8 and Fig. 9As shown, the foldable device opening and closing test device 100 provided in the embodiment of the present application may further include: a first slider 150. At least one first slider 150 is slidably disposed on each first fixed slide bar 110, and the first end and the second end of the folding mechanism 120 are respectively rotatably connected to the corresponding first slider 150. For example, the rotating rod 1221 is rotatably connected to the first slider 150. Fig.10 This is a schematic diagram of the connection between the rotating rod 1221 and the first slider 150 in the foldable device opening and closing test device 100 provided in an embodiment of the present application. Please refer to Fig.10 Combined with Fig. 9 As shown, the rotating rod 1221 can rotate around the first slider 150 along Fig.10 The dotted arrow in the middle rotates back and forth, thereby driving the clamping portion 121 fixedly connected to the rotating rod 1221 to rotate along Fig.10 The device rotates back and forth in the direction indicated by the dotted arrow, thereby realizing the opening and closing test of the foldable device.

[0119] For example, please refer to Fig.10 As shown, in some embodiments of the present application, a fourth bearing hole 123d may be provided on the rotating rod 1221, a fourth bearing 140d may be built in the fourth bearing hole 123d, a third connecting shaft 124c may be fixed on the first slider 150, and the rotating rod 1221 is connected to the first slider 150 by sleeve-mounting the fourth bearing 140d on the third connecting shaft 124c on the first slider 150. It can be understood that, in this way, the friction force when the rotating rod 1221 rotates around the first slider 150 may be reduced, and the opening and closing test device may be prevented from being stuck.

[0120] It should be mentioned that the embodiment of the present application does not limit the number of first sliders 150. For example, each end of each folding mechanism 120 can be equipped with a first slider 150, or the same end of two adjacent folding mechanisms 120 can share a first slider 150. It is only necessary to ensure that the rotating rod 1221 of each folding mechanism 120 can rotate relative to the first fixed slider 110.

[0121] Of course, this application does not stop there. Fig.11 A schematic diagram of the structure of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 1 ,refer to Fig.11As shown, in some embodiments of the present application, the clamping part 121 in the foldable device opening and closing test device 100 may include a bearing seat 1211 and two clamping seats 1212 arranged on the bearing seat 1211, and the two clamping seats 1212 are arranged opposite to each other in the direction of the connection line between the first end and the second end of the folding mechanism 120, wherein the clamping seat 1212 is used to fix the foldable electronic device 10. The two ends of the bearing seat 1211 are respectively connected to the corresponding first sliders 150 on the two first fixed slide bars 110 for rotation. For example, one end of the bearing seat 1211 is fixedly connected to the rotating rod 1221, and the other end is connected to the first slider 150 for rotation, so that the folding mechanism 120 can rotate relative to the first fixed slide bar 110, so that the foldable device can be opened and closed. The function of the bearing seat 1211 is to enable the two clamping seats 1212 located on the bearing seat 1211 to rotate synchronously, so as to avoid the clamping seat 1212 generating torque on the foldable device and causing damage to the foldable device.

[0122] Fig.12 This is a schematic diagram of a clamping seat 1212 and a rotating rod 1221 provided in an embodiment of the present application, refer to Fig.12 Combined with Fig.11 As shown, in some embodiments of the present application, the clamping seat 1212 is provided with a strip groove 12121, and the strip groove 12121 is used to fix the foldable device (for example Figure 6 , Figure 8 and Fig. 9 ), wherein the extended area of ​​the orthographic projection area of ​​the strip groove 12121 on the rotating rod 1221 along the second direction intersects with the rotation axis of the rotating rod 1221 around the connecting rod 1222. The second direction is parallel to the line connecting the first end and the second end of the folding mechanism, that is, the second direction is parallel to the Y axis. For example, as Fig.12 As shown in FIG. 1 , when the width of the clamping seat 1212 is small, the extended area ( Fig.12 The area between the two dotted lines in the middle) intersects with the rotation axis (e.g., axis A) of the rotating rod 1221 around the connecting rod 1222. Alternatively, when the width of the clamping seat 1212 is large, the orthographic projection area of ​​the strip groove 12121 on the rotating rod 1221 along the second direction intersects with the rotation axis of the rotating rod 1221 around the connecting rod 1222.

[0123] Based on this, the foldable electronic device 10 can be assembled into the strip groove 12121 from one end of the strip groove 12121, for example, referring to Fig.13 Combined with Fig.12 As shown, Fig.13The schematic diagram of the foldable electronic device 10 being assembled in the foldable device opening and closing test device 100 in one embodiment of the present application is shown in the figure. The two folding mechanisms 120 are placed horizontally, and the foldable electronic device 10 is assembled into the strip groove 12121 from one side of the folding mechanism 120 along the X-axis direction. In this way, the placement of the foldable electronic device 10 can be facilitated. In addition, since the orthographic projection area of ​​the strip groove 12121 on the rotating rod 1221 along the second direction intersects with the rotation axis of the rotating rod 1221 around the connecting rod 1222, or the extended area of ​​the orthographic projection area of ​​the strip groove 12121 on the rotating rod 1221 along the second direction intersects with the rotation axis of the rotating rod 1221 around the connecting rod 1222, when the foldable electronic device 10 is assembled into the strip groove 12121, the centering operation of the foldable electronic device 10 and the rotating rod 1221 around the rotation axis of the connecting rod 1222 can be reduced, which is conducive to the rapid performance of the opening and closing test.

[0124] Continue to refer Fig.13 As shown, in order to ensure the stability of the foldable electronic device 10 on the foldable device opening and closing testing device 100, the clamping seat 1212 can also have a bearing step 12122, and the bearing step 12122 is located on the side of the strip groove 12121 close to the bearing seat 1211, and the bearing step 12122 is used to place the foldable device.

[0125] In addition, in some embodiments of the present application, the foldable device opening and closing test device 100 may further include a stopper 160, which is disposed on the folding mechanism 120 at the end of the N folding mechanisms 120, and the stopper 160 is disposed on a side of the folding mechanism 120 away from other folding mechanisms 120, and the stopper 160 is used to stop the displacement of the foldable device along the extension direction of the strip groove 12121. For example, Fig.13 As shown, the stopper 160 is disposed on one side of the support seat 1211. When the foldable electronic device 10 is mounted on the foldable device opening and closing test device 100, the stopper 160 can stop the foldable electronic device 10. In this way, the distance between the axis of the foldable electronic device 10 on the side of the stopper 160 and the corresponding side boundary can be determined in advance (e.g. Fig.13 The distance C in the figure is used to adjust the distance between the stopper 160 and the corresponding rotating rod 1221 around the rotation axis of the connecting rod 1222 in the X-axis direction (such as Fig.13 ), so that the distance C is equal to the distance D. In this way, when the foldable electronic device 10 is assembled into the strip groove 12121 and pushed to the stopper 160, the axis of a main body of the foldable electronic device 10 can be aligned or approximately aligned with the rotation axis of the rotating rod 1221 around the connecting rod 1222, which can reduce the centering operation of the foldable electronic device 10 and the rotating rod 1221 around the rotation axis of the connecting rod 1222, which is conducive to the rapid opening and closing test.

[0126] In order to adapt to various models of foldable devices, in some embodiments of the present application, the stopper 160 is retractably arranged on one side of the support seat 1211, and the retracting direction of the stopper 160 is parallel to the extending direction of the strip groove 12121. It can be understood that due to the different models of the foldable electronic device 10, Fig.13 The size of the middle distance C may also be different. The stopper 160 is retractably disposed on one side of the support seat 1211 . That is, the size of the distance D can be adjusted according to the size variation of the distance C to adapt to various models of foldable electronic devices 10 .

[0127] In the foldable device opening and closing test device 100 provided in the embodiment of the present application, the rotating rod 1221 and the connecting rod 1222 of two adjacent folding mechanisms 120 can be located at the same end of the foldable device opening and closing test device, or can be located at different ends of the foldable device opening and closing test device 100. For example, referring to Fig.14 As shown, Fig.14 A schematic diagram of the structure of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 2 The rotating rod 1221 and the connecting rod 1222 of two adjacent folding mechanisms 120 are located at different ends of the folding opening and closing test device, that is, for the folding device opening and closing test device 100 for a two-fold electronic device, one of the rotating rods 1221 and the connecting rod 1222 are located at the end of the folding device opening and closing test device 100 with a smaller Y-axis value, and the other rotating rod 1221 and the connecting rod 1222 are located at the end of the folding device opening and closing test device 100 with a larger Y-axis value. In this way, interference between the two adjacent folding mechanisms 120 when flipping can be avoided.

[0128] Continue to refer Fig.14 As shown, in some embodiments of the present application, the folding device opening and closing test device 100 may further include a connecting rod 170, the extension direction of the connecting rod 170 is parallel to the first end and the second end of the folding mechanism 120, and the two ends of the connecting rod 170 are respectively connected to the connecting rod 1222 of the two adjacent folding mechanisms 120. It is easy to understand that the connecting rod 170 can synchronize the two adjacent folding mechanisms 120 when flipping, thereby avoiding the situation where the folding electronic device 10 is damaged due to the asynchronous flipping of the two adjacent folding mechanisms 120. In addition, the number of first driving devices can be reduced, thereby reducing manufacturing costs. Among them, the first driving device is used to drive the connecting rod 170 to drive the rotating rod 1221 to rotate relative to the first fixed sliding rod 110 through the connecting rod 1222. Its power transmission route can be referred to. Fig.14As shown by the dashed arrow in the middle, when the first driving device drives the connecting rod 170 to reciprocate along the Z axis, the connecting rod 1222 also reciprocates along the Z axis, thereby driving the rotating rod 1221 to rotate. The rotation of the rotating rod 1221 drives the entire folding mechanism 120 to flip relative to the first fixed slide bar 110. When the folding mechanism 120 flips, it drives the first slide bar 150 to slide on the first fixed slide bar 110.

[0129] Fig.15 A schematic diagram of the structure of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 3 ,refer to Fig.15 As shown, Fig.15 The invention discloses an opening and closing test device for a three-fold foldable electronic device, comprising three folding mechanisms 120 and two connecting rods 170, wherein the three folding mechanisms 120 are slidably arranged in the length direction of the first fixed sliding rod 110. The three folding mechanisms 120 each comprise a clamping portion 121, a rotating rod 1221 and a connecting rod 1222, wherein one of the three folding mechanisms 120 comprises a clamping portion 121, two rotating rods 1221 and two connecting rods 1222, and the other two folding mechanisms 120 comprise a clamping portion 121, a rotating rod 1221 and a connecting rod 1222. That is, the three folding mechanisms 120 comprise four rotating rods 1221 and four connecting rods 1222, wherein the rotation axis of the rotating rod 1221 around the connecting rod 1222 of the four rotating rods 1221 and the four connecting rods 1222 respectively correspond to the four rotation axes of the three-fold foldable electronic device. The two linkage rods 170 are respectively connected to the connection rods 1222 of two adjacent folding mechanisms 120 in the three folding mechanisms 120, so as to achieve the purpose of synchronously flipping the three folding mechanisms 120 relative to the first fixed slide bar 110.

[0130] Based on this, for N-fold electronic devices, all can be Fig.15 For example, for a foldable electronic device with four folds, Fig.15 On the basis of the opening and closing test device for the foldable electronic device of the middle three-fold type, another folding mechanism 120 is added, and the folding mechanism 120 includes a clamping portion 121, two rotating rods 1221 and two connecting rods 1222, that is, the four folding mechanisms 120 include six rotating rods 1221 and six connecting rods 1222, and the rotation axes of the rotating rods 1221 around the connecting rods 1222 correspond to the six rotation axes of the foldable electronic device of the four-fold type, and so on.

[0131] Fig.16 Schematic diagram of a state in an opening and closing test of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 3 , Fig.17 Schematic diagram of a state in an opening and closing test of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 4 . refer to Fig.16 and Fig.17 As shown, for the opening and closing test device for a tri-fold foldable electronic device, the three folding mechanisms 120 include four rotating rods 1221 and four connecting rods 1222. The tri-fold foldable electronic device 10 has four rotation axes. The rotation axis of each rotating rod 1221 around the connecting rod 1222 is aligned or approximately aligned with one of the four rotation axes of the tri-fold foldable electronic device 10 in advance. When the opening and closing test is performed, the rotation axis of the rotating rod 1221 around the connecting rod 1222 will always be aligned or approximately aligned with the corresponding rotation axis of the tri-fold foldable electronic device 10 (such as Fig.16 and Fig.17 The foldable electronic device 10 is adapted to the movement of the tri-folded foldable electronic device 10, thereby avoiding the problem of the foldable electronic device 10 being damaged due to the non-concentricity between the opening and closing test device and the foldable electronic device 10 during the opening and closing test.

[0132] Due to the interconnected relationship among the linkage rod 170, the connecting rod 1222, the rotating rod 1221 and the first slider 150, the movement of one can drive the other three to move together. Based on this, regarding the driving scheme of the foldable device opening and closing test device 100 provided in the embodiment of the present application: the first scheme is that the first driving device directly acts on the linkage rod 170, the linkage rod 170 transmits power to the connecting rod 1222, and the connecting rod 1222 drives the rotating rod 1221 to rotate to drive the foldable electronic device 10 to fold and flip synchronously. The second scheme is that the first driving device directly acts on the connecting rod 1222, the connecting rod 1222 transmits power to the connecting rod 1222, the connecting rod 1222 drives the rotating rod 1221 to rotate, and realizes the synchronous folding and flipping of the foldable electronic device 10 through the linkage rod 170. The third solution is that the first driving device directly acts on the first slider 150, and the first slider 150 transmits power to the rotating rod 1221. The rotating rod 1221 pushes the connecting rod 1222 and causes the rotating rod 1221 itself to rotate relative to the connecting rod 1222, and then the foldable electronic device 10 is synchronously folded and flipped through the connecting rod 170.

[0133] Continue to refer Fig.14 As shown, in order to adapt to different axis distances (such as Figure 4 In a foldable electronic device 10 (the distance between the central axis A and the axis B), in some embodiments of the present application, both ends of the linkage rod 170 are rotatably connected to the connecting rods 1222 of two adjacent folding mechanisms 120. For example, Fig.14As shown in , a first bearing hole 123a can be opened on the connecting rod 1222, a first bearing 140a is built in the first bearing hole 123a, a first connecting shaft 124a is fixed on the connecting rod 170, and the connecting rod 1222 is sleeved on the first connecting shaft 124a on the connecting rod 170 through the first bearing 140a to realize the rotation connection between the connecting rod 1222 and the connecting rod 170. In this way, the friction force when the connecting rod 1222 rotates around the connecting rod 170 can be reduced, and the opening and closing test device can be prevented from being stuck.

[0134] about Fig.14 The foldable device opening and closing test device 100 is applicable to the operation of foldable electronic devices 10 with different axis distances. For example, before assembling the foldable device, the connecting rod 1222 with a smaller value on the Y axis can be deflected around the linkage rod 170 in the positive direction of the X axis, or the connecting rod 1222 with a larger value on the Y axis can be deflected around the linkage rod 170 in the negative direction of the X axis. At this time, the distance between the two connecting rods 1222 around the rotation axis of the rotating rod 1221 in the X axis direction will increase, which can be applied to the foldable electronic device 10 with a larger axis distance. On the contrary, the connecting rod 1222 with a smaller value on the Y axis can be deflected around the linkage rod 170 in the negative direction of the X axis, or the connecting rod 1222 with a larger value on the Y axis can be deflected around the linkage rod 170 in the positive direction of the X axis. At this time, the distance between the two connecting rods 1222 around the rotation axis of the rotating rod 1221 in the X axis direction will decrease, which can be applied to the foldable electronic device 10 with a smaller axis distance.

[0135] Fig.18 A schematic diagram of the structure of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 4 ,refer to Fig.18 As shown, the foldable device opening and closing test device 100 provided in the embodiment of the present application may also include a second fixed slide bar 180 and a second slider 181 slidably arranged on the second fixed slide bar 180. The second fixed slide bars 180 are arranged at both ends of the linkage rod 170, and the two ends of the linkage rod 170 are respectively connected to the corresponding second sliders 181, and the extension direction of the second fixed slide bar 180 is perpendicular to the first fixed slide bar 110. Among them, the second fixed slide bar 180 is a fixed component, for example, the second fixed slide bar 180 can be fixed on the base. Based on this, when the first driving device drives the linkage rod 170, the connecting rod 1222 or the first slider 150 to move, the linkage rod 170 can only move along the extension direction of the second fixed slide bar 180, in accordance with the linkage mode in the foldable device opening and closing test device 100 provided in the embodiment of the present application, so that the stability of the foldable device opening and closing test device 100 during operation can be enhanced.

[0136] Fig.19 A schematic diagram of the structure of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 5 ,refer to Fig.19 As shown, in some embodiments of the present application, the first drive device 130 may be a telescopic drive device, for example, a cylinder drive device or a combination of a motor 131 and a lead screw 132. For example, Fig.19 As shown in , the first driving device 130 may include a motor 131 and a lead screw 132, one end of the screw of the lead screw 132 is connected to the rotating shaft of the motor 131, and the nut of the lead screw 132 is connected to the second slider 181, and the extension direction of the screw of the lead screw 132 is parallel to the extension direction of the second fixed slider 180. When the motor 131 drives the lead screw 132, the screw of the lead screw 132 rotates, and the nut of the lead screw 132 reciprocates along the Z-axis direction on the lead screw 132, driving the second slider 181 to reciprocate on the second fixed slider 180, and then the second slider 181 drives the linkage rod 170, and the linkage rod 170 drives the connecting rod 1222, and the connecting rod 1222 drives the rotating rod 1221 to rotate around the first fixed slider 110, thereby realizing the flipping movement of the folding mechanism 120. It can be understood that the telescopic driving device can drive the linkage rod 170 to make repeated movements only along the Z-axis direction, which conforms to the linkage method in the folding device opening and closing test device 100 provided in the embodiment of the present application, and can enhance the stability of the folding device opening and closing test device 100 during operation.

[0137] Fig. 20 A schematic diagram of the structure of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 6 ,refer to Fig. 20 As shown, in some embodiments of the present application, the foldable device opening and closing testing device 100 may further include a fixing seat 190 and two supporting frames 191 .

[0138] Specifically, two support frames 191 are arranged opposite to each other and fixed on the fixing seat 190, and two first fixed slide bars 110 are fixed to the two support frames 191 respectively, and the support frame 191 is also used to fix the second fixed slide bar 180. Among them, the first fixed slide bar 110 and the second fixed slide bar 180 can be fixed to the support frame 191 by a series of commonly used fixing methods, such as bonding, clamping, welding, etc. Of course, the first driving device 130 can also be fixed to the support frame 191. The support frame 191 and the fixing seat 190 are the skeleton of the folding device opening and closing test device 100, which makes the opening and closing test device an integral whole, which is beneficial to the stability of the folding device opening and closing test device 100 during operation.

[0139] Fig.21 A schematic diagram of the structure of a foldable device opening and closing test device 100 provided in an embodiment of the present application Figure 7 ,refer to Fig.21As shown, in some embodiments of the present application, the folding device opening and closing testing device 100 may also include a second driving device 192, which can be fixed on the support frame 191, and the second driving device 192 is used to drive the folding mechanism 120 to slide in the length direction of the first fixed slide rod 110.

[0140] The second drive device 192 may be a telescopic drive device, for example, a cylinder drive device or a combination of a motor 131 and a lead screw 132. Fig.21 In the figure, the second driving device 192 is a cylinder driving device, which is fixed on the support frame 191 and connected to the first slider 150 through the connecting member 193. The second driving device 192 can be connected to an external electric control system to realize the automation of the folding device opening and closing test device 100. Based on the above description, the second driving device 192 can be used to drive the first slider 150 to slide on the first fixed slide bar 110. Due to the existence of the linkage rod 170, the first slider 150, the rotating rod 1221, the connecting rod 1222, the linkage rod 170 and the clamping part 121 can form a linkage. The sliding of the first slider 150 on the first fixed slide bar 110 can drive the rotating rod 1221 to rotate around the connecting rod 1222, thereby driving the clamping part 121 to flip to achieve the purpose of the opening and closing test. At the same time, the connecting rod 1222 can drive the linkage rod 170 to move together. It can be understood that the second driving device 192 can cooperate with the first driving device 130 or replace the first driving device 130 as the power source of the foldable device opening and closing testing device 100.

[0141] In addition, the second driving device 192 can also be used for centering operations. Before the folding device opening and closing test device 100 is assembled into the target test object, the connecting rod 170 can be fixed first. The second driving device 192 drives the first slider 150 and the folding mechanism 120 to slide in the length direction of the first fixed slider 110. The connecting rod 1222 will be deflected relative to the connecting rod 170, that is, the rotating rod 1221 will move along the X-axis direction around the rotation axis of the connecting rod 1222 to complete the centering operation for different models of folding electronic devices 10.

[0142] Of course, in some embodiments of the present application, the second driving device 192 may also be directly connected to the folding mechanism 120 to drive the folding mechanism 120 to slide in the length direction of the first fixed slide bar 110. It is easy to understand that when the foldable device opening and closing test device 100 does not include the linkage rod 170, the second driving device 192 drives the folding mechanism 120 to slide on the first slide bar to complete the centering operation.

[0143] The following describes the installation method of the target test object of the foldable device opening and closing test device 100:

[0144] Fig. 22 This is a schematic diagram of the centering operation of the foldable device opening and closing test device 100 provided in an embodiment of the present application, with reference to Fig. 22 Combined with Fig.21 As shown, before the foldable device opening and closing test device 100 is assembled with the target test object, the first drive device 130 and the second drive device 192 are used as reset devices to reset the foldable device opening and closing test device 100. Then, the positions of the connecting rod 1222 and the rotating rod 1221 are adjusted according to the axis center distance of the target test object (i.e., the centering operation). There are two possible situations after the centering operation, one is that the connecting rod 1222 is parallel to the Y-axis direction, and the other is that the connecting rod 1222 is inclined to the Y-axis direction. Finally, the target test object is pushed flatly into the folding mechanism 120 until it is pushed to the stopper 160, and the installation of the target test object of the foldable device opening and closing test device 100 is completed.
