Description

Technical Field

[0001] The present application relates to the field of testing devices for foldable screen mobile phones, and in particular to a testing device and a testing method for foldable screens. Background Art

[0002] Folding screen mobile phones are gradually attracting people's attention due to their fashionable appearance, compactness and portability. The opening and closing methods of such folding screen mobile phones are similar to those of old flip phones, both of which are opened and closed vertically. In user surveys and online blogger reviews, it was found that users often use folding screen mobile phones with one hand to open them.

[0003] In order to better verify the service life of the product, it is necessary to conduct a durability test on the situation of throwing away the folding screen mobile phone. There are currently two main durability test methods that can be performed: one is that the tester simulates the actual user scenario and continuously manually throws away the folding screen mobile phone for durability testing, but this method is too dependent on manual execution, with large test errors, low test efficiency, and unclear failure excitation mechanism; the second is to use a bending machine to clamp the folding screen mobile phone for a bending durability test, which is an approximate substitute for the durability test in the throwing away scenario, but this method is quite different from the actual user throwing away scenario and cannot effectively simulate the actual user scenario.

[0004] In this regard, there is an urgent need for a testing device specifically for durability testing of foldable screen mobile phones in a thrown-away scenario to fill the gap in durability testing in this thrown-away scenario. Summary of the invention

[0005] The present application provides a testing device and a testing method for a folding screen, which solves the technical problem that the current durability test for folding screens cannot efficiently and accurately simulate the throwing-away scenario.

[0006] In order to achieve the above objectives, this application adopts the following technical solutions:

[0007] In a first aspect, a folding screen testing device is provided, which is used to test an electronic device with a folding screen. The electronic device includes a first shell and a second shell, the first shell and the second shell are rotatably connected to each other, the folding screen is connected to the same side of the first shell and the second shell, the second shell can rotate between an unfolded position and a folded position, when the second shell is in the unfolded position, the second shell is unfolded relative to the first shell, and when the second shell is in the folded position, the second shell is folded relative to the first shell, the folding screen testing device includes a swinging mechanism and a shooting mechanism, the swinging mechanism includes a connecting seat and a first rotating seat, the connecting seat is connected to the first rotating seat, the first shell can be connected to the connecting seat, the first rotating seat can drive the connecting seat to rotate, so as to swing the second shell to the unfolded position; when the second shell is in the unfolded position, the shooting mechanism can collect image information of the folding screen.

[0008] When the test device is used, the first shell is first installed on the connecting seat, and then the first rotating seat is started. The connecting seat is driven to rotate by the first rotating seat, and the connecting seat swings the electronic device so that the second shell rotates to the unfolded state. At this time, the image information of the folding screen is collected by the shooting mechanism. This is to complete a test. After the single test is completed, it can be judged whether the electronic device is qualified according to the image information, and the test result is recorded. If the test result is unqualified, the test is stopped, and the current number of swings, swing speed, current ambient temperature and humidity and other test conditions are recorded. The test condition is the failure condition; if the test result is qualified, it means that the electronic device has not failed, and the electronic device can be switched to the folded state, and other mechanisms are reset, and then the test is repeated. The test device only fixes the first shell, and rotates the second shell to the unfolded position by swinging the first shell. The above scheme is more in line with the scene of users swinging the electronic device in actual use, which can effectively stimulate the failure risk of the folding screen of the electronic device when it is thrown away with one hand, and ensure the accuracy and consistency of the durability test.

[0009] In some embodiments of the first aspect, the swinging mechanism further includes a limit block, which is connected to the connecting seat, and the limit block is located on the rotation path of the second shell rotating toward the folded position, and the limit block is used to limit the second shell from rotating to the folded position to prevent the first shell and the second shell from being completely closed. For example, when the second shell rotates toward the folded position, it can abut against the limit block, and the second shell stays in the preparatory position, and the preparatory position is between the folded position and the unfolded position, and the second shell and the first shell are at a preset angle. At this time, the limit block limits the rotation of the second shell toward the folded position, and when the first rotating seat drives the connecting seat to rotate, the second shell can be swung from the preparatory position to the unfolded position. In this way, the limit block can simulate the scene in which the user inserts a finger between the first shell and the second shell before swinging the electronic device, which is more in line with the actual swinging scene, and the test data is more accurate. At the same time, the swinging speed or swinging acceleration required to swing the second shell can be reduced, and the test difficulty can be reduced.

[0010] Specifically, the stop block has a chamfered surface, and the thickness of the stop block gradually increases in the direction away from the rotation axis of the second shell. At this time, the cross-section of the stop block is wedge-shaped, and the chamfered surface is used for the second shell to abut against. In other words, when the second shell rotates toward the folded position, it can abut against the chamfered surface. The chamfered surface can increase the contact area between the stop block and the folding screen to reduce the pressure per unit area of ​​the folding screen and avoid damaging the folding screen.

[0011] In some embodiments of the first aspect, the connecting base includes a first clamping jaw and a second clamping jaw, the first clamping jaw is connected to the rotating shaft of the first rotating base, the second clamping jaw is movably connected to the first clamping jaw, and the movably connected manner may be a rotating connection, a sliding connection, etc., and the first clamping jaw and the second clamping jaw jointly clamp the first shell. The first clamping jaw and the second clamping jaw clamp the first shell to fix the position of the first shell, so as to facilitate the connection and disassembly of the first shell.

[0012] Specifically, the second jaw is slidably connected to the first jaw, and the limit block is detachably connected to the first jaw and the second jaw, respectively. At this time, the limit block can limit the opening of the first jaw and the second jaw to lock the position of the second jaw, thereby preventing the first shell from slipping off between the first jaw and the second jaw. Among them, a first buffer pad is provided on the side of the first jaw facing the second jaw, and a second buffer pad is provided on the side of the second jaw facing the first jaw. The first buffer pad and the second buffer pad can be made of flexible material or elastic material to buffer the clamping force of the first jaw and the second jaw to avoid wear on the first shell, while increasing the friction force of the first jaw and the second jaw on the first shell, further preventing the first shell from slipping off from the connecting seat.

[0013] In some embodiments of the first aspect, the folding screen test device further includes a reset mechanism, and when the second shell is in the unfolded position, the reset mechanism can move the second shell to rotate toward the folded position, wherein when the second shell stops moving, the second shell may be in the folded position or may not reach the folded position. In an embodiment in which a limit block is provided on the connecting seat, when the second shell stops rotating, the second shell may abut against the limit block or may not reach the limit block, which is not limited here. In this way, the electronic device is folded through the reset mechanism in preparation for the next swing-away test.

[0014] The reset mechanism includes a toggle member and a second rotating seat, the toggle member is connected to the second rotating seat, and the second rotating seat can drive the toggle member to rotate, so that the toggle member resets the second shell during the rotation process. In this way, the second shell is reset by the toggle member. The reset mechanism has a simple structure and is convenient for quickly resetting the second shell.

[0015] Specifically, the toggle member includes a toggle rod and a connecting rod, the connecting rod is connected between the toggle rod and the second rotating seat, the second rotating seat drives the connecting rod to rotate, so as to drive the toggle rod to move in a circular motion, and the second housing is located on the motion path of the toggle rod until the second housing is reset to the preparatory position, so that the toggle member resets the second housing through the toggle rod. The setting of the connecting rod increases the torque of the toggle rod, which not only increases the range of the toggle rod, but also reduces the force required for the toggle rod to reset the second housing.

[0016] More specifically, two connecting rods are provided, the two connecting rods are parallel to each other and perpendicular to the rotation axis of the connecting rod, the shifting rod is connected between the two connecting rods, the shifting rod is parallel to the rotation axis of the connecting rod, and the two connecting rods avoid the second housing. When the second housing is in the unfolded position, it can be located between the two connecting rods to save space and reduce the relative displacement between the shifting rod and the second housing when the shifting member rotates.

[0017] To avoid scratching the second shell, the toggle member also includes a gasket connected to the toggle rod. When the toggle rod toggle the second shell, the gasket abuts against the second shell. At this time, the gasket is located between the second shell and the toggle rod. The gasket is made of flexible or elastic material and can buffer the force applied by the toggle rod to the second shell.

[0018] In some embodiments of the first aspect, the first rotating seat can drive the connecting seat to rotate toward a first direction, and the second rotating seat can drive the toggle member to rotate toward a second direction, and the first direction is opposite to the second direction. When the second shell abuts against the limit block, the second shell is located in the first direction of the first shell. The second shell rotates from the preparatory position toward the first direction to the deployed position, so that when the toggle member rotates toward the second direction, the second shell can be quickly reset.

[0019] Specifically, after the second housing is reset, the first rotating seat can drive the connecting seat to reset, and the second rotating seat can drive the toggle member to reset. In this way, the connecting seat, the toggle member and the second housing are all reset, so as to repeat the same steps for the next detection.

[0020] Optionally, when the second shell is swung open to the unfolded position, the rotation angle of the connecting seat is 90°-150° to fully swing open the second shell.

[0021] Optionally, the rotation angle of the toggle member to abut against the second shell is 20°-30°. It can be understood that the second rotating seat can make the toggle member abut against the second shell after driving the toggle member to rotate 20°-30°, and the second rotating seat continues to drive the toggle member to rotate, and the toggle member can toggle the second shell to reset, so that the toggle member can be spaced from the second shell in the deployed position when not started, so as to reserve space for the second shell to shake when it is swung to the deployed position.

[0022] In some embodiments of the first aspect, the shooting mechanism includes a camera module, a lighting board and a processor. The lighting board is connected to the camera module, the camera module is used to collect image information of the folding screen, the lighting board can emit light toward the folding screen to improve the clarity of the image, and the processor can save the image information collected by the camera module, detect the image information, and determine whether the folding screen is invalid.

[0023] In some embodiments of the first aspect, the testing device for the folding screen also includes a bracket, and the swinging mechanism and the shooting mechanism are both connected to the bracket. The bracket can make the swinging mechanism and the shooting mechanism form a whole, fix the position of each mechanism, and facilitate transportation and use.

[0024] In some embodiments of the first aspect, the testing device for the folding screen further includes a temperature and humidity control mechanism, which can adjust the temperature and humidity of the environment so that the temperature and humidity meet the testing requirements.

[0025] In a second aspect, a folding screen testing method is provided, which is applied to the testing device of each of the above embodiments, and the testing method includes:

[0026] S1, connecting the first housing to the connecting seat of the swinging mechanism;

[0027] S2. Under the set test conditions, the connecting seat is rotated by the first rotating seat until the second shell is thrown open to the unfolded position;

[0028] S3, after the second housing is swung open to the unfolded position, the connecting seat is controlled to stop rotating through the first rotating seat;

[0029] S4, after the connecting base stops rotating, collecting image information of the folding screen through a shooting mechanism;

[0030] S5, after the photographing mechanism has collected the image information, resetting the second housing and the connecting seat;

[0031] S6, performing abnormality detection on the folding screen in the image information to obtain a detection result;

[0032] S7, if the test result is qualified and the test number is not reached, execute S2 again and perform the next test;

[0033] S8. If the test result is unqualified, the electronic device is judged to be ineffective, the test is stopped, and the current test conditions and the number of tests are recorded;

[0034] S9. If the test result is qualified and the test times have been reached, the electronic device is judged to be qualified, the test is stopped, and the current test conditions and the test times are recorded.

[0035] The test method controls the connection seat to rotate by the first rotating seat to swing the electronic device to the unfolded state, and then collects the image information of the folding screen through the shooting mechanism and performs abnormal detection. When the test result is qualified and the number of tests is not reached, the next test is performed again until the test result is unqualified or the number of tests is reached, and then the test is stopped. When the test result is still qualified when the number of tests is reached, the electronic device is judged to be qualified, and the current test conditions and the number of tests are recorded, indicating that the electronic device can meet the design requirements under the current test conditions and the number of tests. When the number of tests is not reached and the test result is already unqualified, the electronic device is judged to be failed, and the current test conditions and the number of tests are recorded. The test conditions and the number of tests are the failure conditions of the electronic device, and the number of tests is the swing folding life of the electronic device under the test conditions. According to the abnormal area in the image information that causes the test result to be unqualified, the weak link or dangerous part of the electronic device under the test condition can be found. The test method can effectively simulate the scene of the user actually swinging the electronic device, and through repeated detection, the failure of the electronic device is stimulated. The test results obtained by the test method are highly accurate and consistent, efficient and convenient, filling the gap in the durability test of electronic devices under the swinging scene.

[0036] In some embodiments of the second aspect, before step S1, the test method further includes: setting test conditions and the number of times the electronic device is thrown away under the test conditions, and the test conditions include: the speed of the first rotating seat when the first rotating seat rotates and the temperature and humidity of the environment in which the electronic device is located. It can be understood that under the set test conditions, if the test result is qualified, S2 is executed again until the number of cycle detections reaches the number of times the electronic device is thrown away. If the test result is still qualified at this time, the electronic device is judged to be qualified. If the number of cycle detections is unqualified before reaching the number of times the electronic device is thrown away, the number of times the detection has been performed is recorded, that is, the number of detections, which is the throwing and folding life of the electronic product under the test conditions. In this way, by setting different factors and parameters, different users and different usage environments can be better simulated, and then the swinging and folding life of the electronic device under different test conditions can be obtained, thereby improving the accuracy of the test results.

[0037] In some embodiments of the second aspect, the test conditions include: a first condition, a second condition, and a third condition.

[0038] The first condition includes: a first swinging speed, a first temperature and a first humidity. It can be understood that the first swinging speed has only one speed value, the first temperature has only one temperature value, and the first humidity has only one humidity value. When the detection is performed under the first condition, it indicates that the first rotating seat rotates at the first swinging speed, the ambient temperature is the first temperature, the ambient humidity is the first humidity, and the number of detections is the number of swingings corresponding to the first condition.

[0039] The second condition includes: a second swinging speed, a second temperature and a second humidity. The second swinging speed has multiple speed values, and each speed value corresponds to a number of swinging times. It can be understood that the first swinging speed has multiple speed values, the first temperature has only one temperature value, and the first humidity has only one humidity value. When the detection is performed under the second condition, it indicates that the first rotating seat rotates at different speed values ​​in sequence, and the corresponding number of swinging times must be performed at each speed value. The ambient temperature is the second temperature, the ambient humidity is the second humidity, and the number of detections is the sum of the number of swinging times corresponding to each speed value.

[0040] The third condition includes: a third swinging speed, a third temperature and a third humidity. The third temperature has multiple temperature values, and each temperature value corresponds to a number of swinging off. The third temperature has multiple humidity values, and each humidity value corresponds to a number of swinging off. It can be understood that the first swinging speed has only one speed value, the first temperature has multiple temperature values, and the first humidity has multiple humidity values. When the detection is performed under the second condition, it indicates that the first rotating seat rotates at the third swinging speed, the ambient temperature is set to different temperature values ​​in turn, and the corresponding number of swinging off must be executed at each temperature value. The ambient humidity is set to different humidity values ​​in turn, and the corresponding number of swinging off must be executed at each humidity value. The number of detections is the sum of the number of swinging off corresponding to each temperature value and the number of swinging off corresponding to each humidity value.

[0041] Among them, when testing the same electronic device, the test order of the test conditions is: first condition, second condition, third condition. It can be understood that when testing the same electronic device, the test is first performed under the first condition, and after the number of tests under the first condition is completed, the test is then performed under the second condition, and after the number of tests under the second condition is also completed, the test is then performed under the third condition, until the number of tests under the third condition is also completed, then the total number of tests under the test condition is reached.

[0042] In this way, the complex and changeable usage environment of the user can be simulated according to the above test conditions to obtain the swing and folding life of the electronic device in the usage environment, thereby enriching the usage environment and further improving the accuracy of the test results.

[0043] It is understandable that the above-mentioned unqualified test results include: detecting leakage of the folding screen or damage of the protective film in the image information. When the above-mentioned situation occurs, it can be determined that the electronic device fails. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0056] In order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and the like are used to distinguish the same items or similar items with basically the same functions and effects. For example, the first rotating seat and the second rotating seat are only used to distinguish different limiting parts, and their order is not limited. Those skilled in the art can understand that the words "first", "second" and the like do not limit the quantity and execution order, and the words "first", "second" and the like do not necessarily limit them to be different.

[0057] It should be noted that, in this application, the words "in one embodiment" or "for example" are used to indicate examples, illustrations or explanations. Any embodiment or design described in this application as "in one embodiment" or "for example" should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the words "in one embodiment" or "for example" is intended to present the relevant concepts in a specific way.

[0058] In this application, unless otherwise clearly specified and limited, the terms "connected", "connection" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0060] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0061] An electronic device with a folding screen includes a first shell and a second shell that are rotatably connected to each other, and the folding screen is connected to the same side of the first shell and the second shell. Under different usage requirements, the electronic device can switch between an unfolded state and a folded state. When the electronic device is unfolded to the unfolded state, the first shell and the second shell rotate in opposite directions, the second shell is unfolded relative to the first shell and is located at the unfolded position, and the folding screen is flattened or has a certain angle. When the electronic device is folded to the folded state, the first shell and the second shell rotate in opposite directions, the second shell is folded relative to the second shell and is located at the folded position, and the folding screen is also folded. It should be noted that the unfolded position and the folded position of the second shell are relative to the position of the first shell. The folding screen can be used to display information and provide an interactive interface for the user. When the user uses the electronic device to browse web pages, information, videos, or play games, touch screen operations, etc., the electronic device can be switched from the folded state to the unfolded state. The electronic device can realize a large-screen display of the folding screen to provide users with richer information and bring users a better use experience. When the user has finished using the electronic device, the electronic device can be switched from the unfolded state to the folded state to reduce the volume of the electronic device and facilitate the storage of the electronic device. The electronic device includes but is not limited to a mobile phone, a game console, a test machine, etc. This application does not impose any special restrictions on the specific form of the above electronic device.

[0062] It should be noted that the electronic device may be an electronic device with an inward folding screen, that is, when the electronic device is in the folded state, the folding screen is located on the inner side of the first shell and the second shell facing each other. In other examples, the electronic device may also be an electronic device with an outward folding screen, that is, when the electronic device is in the folded state, the folding screen is located on the outer side of the first shell and the second shell facing each other.

[0063] See also Figure 1 , Figure 1 The foldable screen test device is a three-dimensional structural diagram. Taking the foldable screen mobile phone 90 as an example, the foldable screen mobile phone 90 includes a first shell 91 and a second shell 92 that are rotatably connected, and the foldable screen is connected to the same side of the first shell 91 and the second shell 92. The foldable screen mobile phone 90 can be opened and closed vertically, that is, switched between the unfolded state and the folded state. When the foldable screen mobile phone 90 is in the unfolded state, the foldable screen is flattened, the first shell 91 and the second shell 92 are in the same plane and together form the long side of the foldable screen mobile phone 90, so that the foldable screen mobile phone 90 can be used vertically. When the foldable screen mobile phone 90 is in the folded state, the foldable screen is folded in half, and the screen part located in the first shell 91 is attached to the screen part located in the second shell 92, and the length of the foldable screen mobile phone 90 is halved for the convenience of user storage. The foldable screen mobile phone 90 has gradually attracted people's attention due to its stylish shape, compact and portable features. The vertical opening and closing of the foldable screen mobile phone 90 can be operated by the user with one hand, similar to operating an old flip phone. During user surveys and online blogger reviews, it was found that when users operate the foldable screen mobile phone 90 vertically with one hand, there is often a scenario in which the user swings the foldable screen mobile phone 90 open with one hand, that is, holding the first shell 91, and then swinging the first shell 91 to rotate, and the centrifugal force of the swinging is used to make the second shell 92 rotate back to the first shell 91 to unfold, without the need to manually apply force to the second shell 92.

[0064] When the user uses the foldable screen mobile phone 90, the user needs to frequently swing the foldable screen mobile phone 90, and the foldable screen mobile phone 90 constantly switches between the unfolded state and the folded state. In this way, the foldable screen will also be constantly folded and unfolded. In the long run, it is easy to cause failures such as screen peeling and leakage or protective film breakage, which affects the service life of the foldable screen mobile phone 90. In order to manufacture a foldable screen mobile phone 90 that can meet the needs of users, it is often necessary to perform a durability test of the foldable screen to better verify the service life of the product. There are two main durability testing methods that can be performed currently: one is that the tester simulates the actual user's throwing away scenario, and repeatedly performs manual folding and manual throwing away operations on the foldable screen mobile phone 90, but this method relies too much on manual execution, with large test errors, low test efficiency, and unclear failure excitation mechanism; the second is to use a bending machine to clamp the foldable screen mobile phone 90 for a bending durability test, which approximately replaces the durability test in the throwing away scenario, but the bending machine generally uses two clamps to clamp the first shell 91 and the second shell 92 respectively, and then drives the second shell 92 to unfold or fold relative to the first shell 91 by moving the clamp, rather than by the centrifugal force of the swing. This method is quite different from the actual user throwing away scenario and cannot effectively simulate the actual user throwing away scenario.

[0065] It can be seen that the current durability testing methods are unable to efficiently and accurately simulate the throwing-away scenario. Therefore, there is an urgent need for a testing device specifically for the durability testing of the folding screen mobile phone 90 degrees in the throwing-away scenario to fill the gap in the durability testing in this throwing-away scenario.

[0066] In order to solve the above problems, the present application provides a folding screen test device and test method. The folding screen test device is hereinafter referred to as the test device, which can be used to test electronic devices with folding screens. Specifically, the folding screen mobile phone 90 can be used as a prototype to be tested, that is, the test device can specifically perform durability tests on the folding screen mobile phone 90 when it is thrown away, filling the gap in durability tests under the throwing away scenario. Specifically, the test device can efficiently measure the service life of the folding screen mobile phone 90 in the throwing away scenario and specified conditions, predict or verify the weak links and dangerous parts of the structure, so as to effectively stimulate the failure risk of the screen, middle frame and other structures of the folding screen mobile phone 90 when it is thrown away with one hand, and measure the failure conditions, so as to ensure the accuracy and consistency of the test.

[0067] See also Figure 1 The testing device provided in the embodiment of the present application includes a swinging mechanism 10, a shooting mechanism 20, a resetting mechanism 30, a temperature and humidity control mechanism 40 and a bracket 50.

[0068] The swinging mechanism 10 is used to install the folding screen mobile phone 90, wherein the first shell 91 of the folding screen mobile phone 90 is connected to the swinging mechanism 10, and the swinging mechanism 10 can swing the first shell 91 so that the second shell 92 rotates to a flattened position.

[0069] Specifically, the throwing-off mechanism 10 includes a first rotating seat 11 and a connecting seat 12. The first rotating seat 11 is connected to the connecting seat 12. The connecting seat 12 is used to connect the first shell 91. When the throwing-off mechanism 10 is not started, the second shell 92 is not in the unfolded state. The first rotating seat 11 can drive the connecting seat 12 to rotate so as to throw the second shell 92 to the unfolded position. The rotation speed of the first rotating seat 11 rotating the connecting seat 12 is the throwing-off speed of the folding screen mobile phone 90. The throwing-off speed can be set as one or more groups before the test. The first rotating seat 11 reads the set value and drives the connecting seat 12 to rotate according to the set value. It can be understood that the throwing-off speed can be a constant value, that is, uniform motion, or it can have acceleration. Among them, the force to throw off the second shell 92 can be the centrifugal force generated by the connecting seat 12 rotating the folding screen mobile phone.

[0070] It should be noted that the rotation axis of the connecting seat 12 and the rotation axis of the second housing 92 may coincide or be spaced apart, and when the first rotating seat 11 drives the connecting seat 12 to rotate, there may also be a uniform speed section, in which the connecting seat 12 rotates at a uniform speed. In addition, the rotation of the connecting seat 12 may also be non-circular rotation, which is not limited here.

[0071] The shooting mechanism 20 is used to collect image information of the folding screen mobile phone 90 in a flattened state. It can be understood that when the second shell 92 is in the flattened position, the shooting mechanism 20 collects image information of the folding screen mobile phone 90, wherein the image information includes the folding screen and the middle frame.

[0072] Specifically, when the second shell 92 is in the unfolded position, the shooting mechanism 20 can collect image information of the folding screen. It can be understood that the image information can be compared with the image information of qualified products to determine whether the folding screen mobile phone 90 in the current state is invalid. For example, if the screen peels off and leaks or the protective film is damaged, the folding screen is judged to be invalid. This judgment can be made by the shooting mechanism 20 itself, or by other equipment independent of the shooting mechanism 20, or by manual judgment. It should be noted that the image information may include but is not limited to the area where the folding screen is located. In other embodiments, the image information may also include the area where the middle frame is located. If the middle frame is detected to be damaged, the folding screen is judged to be invalid.

[0073] When the test device is in use, the first shell 91 is first installed on the connecting seat 12, and then the first rotating seat 11 is started. The connecting seat 12 is driven to rotate by the first rotating seat 11. The connecting seat 12 swings the folding screen mobile phone 90 during the rotation process, so that the second shell 92 rotates to the unfolded state. At this time, the image information of the folding screen is collected by the shooting mechanism 20 to obtain the test result. This is to complete one test. After the single test is completed, it can be judged whether the folding screen mobile phone 90 is qualified according to the test result. If the test result is unqualified, the test is stopped, and the current number of swings, swing speed, current ambient temperature and humidity and other test conditions are recorded. The test condition is the failure condition; if the test result is qualified, it means that the electronic device has not failed, and the folding screen mobile phone 90 and the connecting seat 12 can be reset, and then the test can be re-performed. The test device only fixes the first shell 91, and there is no other structure to apply force to the second shell 92. Instead, the centrifugal force generated by shaking the first shell 91 causes the second shell 92 to rotate to the unfolded position, which is more in line with the scenario of users throwing away the folding screen mobile phone 90 in actual use, and can effectively stimulate the failure risk that may occur when the folding screen mobile phone 90 is thrown away with one hand, ensuring the accuracy and consistency of the durability test. It should be noted that if the test result is qualified when the set number of throws has been reached, it means that the folding screen mobile phone 90 has met the service life requirements, and the test can be stopped at this time.

[0074] In some embodiments, the first rotating seat 11 can be a motor, in which case the first rotating seat 11 has a rotating shaft 111, the first rotating seat 11 is connected to the support seat 51, the rotating shaft 111 is rotatably connected to the third support plate 54, and the connecting seat 12 is connected to the rotating shaft 111 of the first rotating seat 11. When the first rotating seat 11 is started, the rotating shaft 111 rotates and drives the connecting seat 12 to move in a circle. In other embodiments, the first rotating seat 11 can also be other structural parts, and the first rotating seat 11 can drive the connecting seat 12 to move in a circle, rotate in place, or move along a curve protruding to one side, which is not limited here.

[0075] Please combine Figure 2 , Figure 2 1 is an exploded view of the swing-off mechanism 10 of the test device in the embodiment of the present application. Specifically, the connection seat 12 includes a first clamping jaw 121 and a second clamping jaw 122, the first clamping jaw 121 is connected to the rotating shaft 111 of the first rotating seat 11, and the second clamping jaw 122 is movably connected to the first clamping jaw 121, and the first clamping jaw 121 and the second clamping jaw 122 jointly clamp the first shell 91. The connection between the connection seat 12 and the folding screen mobile phone 90 is achieved by clamping the first shell 91, which facilitates the installation and removal of the first shell 91.

[0076] Optionally, the second clamp 122 is slidably connected to the first clamp 121. When the folding screen mobile phone 90 needs to be connected, the second clamp 122 can be slid away from the first clamp 121 first, and then the first shell 91 is placed between the first clamp 121 and the second clamp 122, and then the second clamp 122 is slid close to the first clamp 121 until the first clamp 121 and the second clamp 122 jointly clamp the first shell 91. It should be noted that after the first clamp 121 and the second clamp 122 clamp the first shell 91, the position of the second clamp 122 needs to be locked to prevent the first shell 91 from slipping off the connecting seat 12. There are many ways to lock the position of the second clamp 122. For example, the second clamp 122 can be locked to the first clamp 121 by a locking structure, and the second clamp 122 can also be locked to other fixed structural parts by a locking structure. The first clamping jaw 121 and the second clamping jaw 122 can also elastically clamp the first shell 91, that is, the first clamping jaw 121 and the second clamping jaw 122 both elastically abut against the first shell 91, and at this time, the clamping elastic force must be greater than the force of the connecting seat 12 swinging the folding screen mobile phone 90 to ensure that the first shell 91 will not slip off the connecting seat 12. In other embodiments, the detachable connection between the second clamping jaw 122 and the first clamping jaw 121 can also be a rotating connection, a threaded connection, etc., which is not limited here.

[0077] In order to prevent the first jaw 121 and the second jaw 122 from causing wear to the first shell 91, a first buffer pad 123 is provided on the side of the first jaw 121 facing the second jaw 122, and a second buffer pad 124 is provided on the side of the second jaw 122 facing the first jaw 121. When the first jaw 121 and the second jaw 122 clamp the first shell 91, the first buffer pad 123 is located between the first jaw 121 and the first shell 91, and the second buffer pad 124 is located between the second jaw 122 and the second shell 92. The first buffer pad 123 and the second buffer pad 124 can be made of flexible material or elastic material to buffer the clamping force of the first jaw 121 and the second jaw 122, thereby preventing the first shell 91 from being worn, and at the same time increasing the friction force of the first jaw 121 and the second jaw 122 on the first shell 91, thereby further preventing the first shell 91 from slipping off the connecting seat 12.

[0078] See also Figure 3 , Figure 3 It is a top view of the swinging mechanism 10 of the test device in the embodiment of the present application. Under normal circumstances, when the user needs to swing the folding screen mobile phone 90, he will first pry open the second shell 92 with his fingers to leave a gap between the first shell 91 and the second shell 92, and then swing the folding screen mobile phone 90. In order to restore the actual swinging scene, the swinging mechanism 10 in this embodiment also includes a limit block 13, which is connected to the connecting seat 12 and is located on the rotation path of the second shell 92 folded toward the first shell 91. The limit block 13 is used to limit the second shell 92 from rotating to the folded position to prevent the first shell 91 and the second shell 92 from being completely closed.

[0079] In some embodiments, the stopper 13 can be used for the second shell 92 to abut against, so that the second shell 92 stays in a preparatory position at a preset angle with the first shell 91, and the preparatory position is located between the folded position and the unfolded position. The first rotating seat 11 can swing the second shell 92 from the preparatory position to the unfolded position by driving the connecting seat 12 to rotate. It can be understood that the stopper 13 is located on the rotation path of the second shell 92 from the unfolded position to the folded position. When the second shell 92 rotates toward the folded position, it can abut against the stopper 13. At this time, the stopper 13 limits the second shell 92 from continuing to rotate toward the folded position, and makes the second shell 92 stay in the preparatory position. In this way, the stopper 13 can simulate the scene of the user's finger inserted between the first shell 91 and the second shell 92 to pry open the second shell 92, which is more in line with the actual throwing scene, and the test data is more accurate. At the same time, the throwing speed or throwing acceleration required to throw the second shell 92 can be reduced, which reduces the difficulty of the test. Among them, the preset angle is less than 90°. Optionally, the preset angle may be 20°-40°.

[0080] It should be noted that the above-mentioned second shell 92 abutting against the limit block 13 means that when the second shell 92 is in the preparatory position, the second shell 92 can only fit against the limit block 13 without applying force to the limit block 13, or can apply a certain pressure to the limit block 13 under the action of the shaft force, which is not limited here.

[0081] Optionally, the limit block 13 is detachably connected to the first clamping jaw 121 and the second clamping jaw 122, respectively, and can limit the opening of the first clamping jaw 121 and the second clamping jaw 122. It can be understood that after the first clamping jaw 121 and the second clamping jaw 122 clamp the first shell 91, one end of the limit block 13 can be detachably connected to the first clamping jaw 121, and the other end can be detachably connected to the second clamping jaw 122, so that not only the connection between the limit block 13 and the connecting seat 12 is realized, but also the relative position of the first clamping jaw 121 and the second clamping jaw 122 can be fixed, thereby preventing the first shell 91 from coming off the connecting seat 12. Specifically, the limit block 13 can be set as a hollow structure, and can be detachably connected to the first clamping jaw 121 and the second clamping jaw 122 respectively by screws 14.

[0082] Since the second shell 92 abuts against the limit block 13 through the screen, in order to prevent the limit block 13 from damaging the folding screen, the limit block 13 has a chamfered surface 131, and the chamfered surface 131 is used for the second shell 92 to abut. Among them, the thickness of the limit block 13 gradually increases in the direction away from the rotation axis of the second shell 92, the thickness direction of the limit block 13 is the rotation direction of the second shell 92, and the cross-section of the limit block 13 perpendicular to the thickness direction is wedge-shaped. When the second shell 92 abuts against the limit block 13, the second shell 92 is located in the preparation position, and the chamfered surface 131 is in contact with the folding screen on the second shell 92. In this way, the contact area between the limit block 13 and the second shell 92 is increased to reduce the pressure per unit area of ​​the folding screen and avoid damaging the folding screen. In the illustrated embodiment, the preset angle can be 30°.

[0083] See also Figure 4 , Figure 4 It is a partial structural diagram of the test device in the embodiment of the present application, in which only the throwing-off mechanism 10 and the resetting mechanism 30 are depicted. Among them, the resetting mechanism 30 is used to fold the folding screen mobile phone 90. It can be understood that the resetting mechanism 30 can move the second shell 92 to rotate toward the folded position. Among them, when the second shell 92 stops moving, the second shell 92 may be in the folded position, or it may not reach the folded position. In the embodiment in which a limit block 13 is provided on the connecting seat 12, when the second shell 92 stops rotating, the second shell 92 may abut against the limit block 13, or it may not have reached the limit block 13, which is not limited here.

[0084] Optionally, when the second housing 92 is in the unfolded position, the reset mechanism 30 can move the second housing 92 to reset the second housing 92. Here, the reset of the second housing 92 refers to the second housing 92 returning to the position before being thrown away. In this way, the folding screen mobile phone 90 can be folded by the reset mechanism 30, so as to facilitate the next throwing away test, realize the automation of the folding process of the folding screen mobile phone, and ensure the consistency of the test.

[0085] In some embodiments, the swinging mechanism 10 includes a limit block 13, and the reset mechanism 30 includes a second rotating seat 31 and a toggle member 32. The second rotating seat 31 is connected to the toggle member 32, and the second rotating seat 31 can drive the toggle member 32 to rotate, so that the toggle member 32 can reset the second shell 92 during the rotation process. In the following embodiments, the second shell 92 is described as being in the preparatory position before being swinging, and when the second shell 92 is swinging to the unfolded position, the toggle member 32 can reset the second shell 92 to the preparatory position.

[0086] It should be noted that the second rotating seat 31 can be in a uniform speed motion or a variable speed motion in the process of driving the toggle member 32 to rotate, which is not limited here. When the toggle member 32 drives the second shell 92 to rotate toward the preparatory position, the toggle member 32 can directly toggle the second shell 92 to the preparatory position. In this case, the toggle member 32 and the second shell 92 are not separated before the second shell 92 reaches the preparatory position. The toggle member 32 can also be separated from the second shell 92 before the second shell 92 reaches the preparatory position. At this time, the second shell 92 can continue to rotate by inertia and reach the preparatory position. Among them, the toggle member 32 can stop moving after separating from the second shell 92, or it can continue to rotate for a distance and then stop moving, which is not limited here.

[0087] The second rotating seat 31 may be a motor, in which case the second rotating seat 31 has a rotating shaft, the toggle member 32 is connected to the rotating shaft of the second rotating seat 31, and the rotating axis of the second rotating seat 31 is parallel to the rotating axis of the first rotating seat 11. When the second rotating seat 31 is started, the rotating shaft rotates and drives the toggle member 32 to rotate around the rotating shaft. In other embodiments, the second rotating seat 31 may also be other structural members, and the second rotating seat 31 may drive the toggle member 32 to move linearly, circularly, or curvilinearly, etc., which is not limited here.

[0088] For more details, please refer to Figure 4The toggle member 32 includes a connecting rod 321 and a toggle rod 322. The connecting rod 321 is connected between the toggle rod 322 and the second rotating seat 31. The second rotating seat 31 drives the connecting rod 321 to rotate, so as to drive the toggle rod 322 to move in a circular motion. The toggle member 32 toggle the second housing 92 to reset through the circular motion of the toggle rod 322. In other words, the toggle rod 322 can toggle the second housing 92 to rotate toward the preparatory position through the circular motion. In this way, the toggle rod 322 increases the torque through the connecting rod 321, which not only reduces the force required to toggle the second housing 92, but also increases the movable distance of the toggle rod 322, so as to facilitate the rapid reset of the second housing 92.

[0089] Optionally, two connecting rods 321 are provided, the two connecting rods 321 are parallel to each other and perpendicular to the rotation axis of the connecting rod 321, the two connecting rods 321 are of equal length, the lever 322 is connected between the two connecting rods 321, the lever 322 is parallel to the rotation axis of the connecting rod 321, the lever 322 and the two connecting rods 321 together form a C-shaped structure, and the two connecting rods 321 avoid the second shell 92. When the second shell 92 is swung open to the unfolded position, the second shell 92 can be located between the two connecting rods 321, and the rotation direction of the swivel member 32 is the same as the direction in which the second shell 92 rotates from the unfolded position to the preparatory position, so as to reduce the distance between the reset mechanism 30 and the swivel mechanism 10.

[0090] In other embodiments, the toggle member 32 may also completely avoid the second shell 92 in the vertical direction, and the rotation direction of the toggle member 32 may also be opposite to the direction in which the second shell 92 rotates from the deployed position to the ready position.

[0091] In order to prevent the toggle member 32 from scratching the second housing 92, the toggle member 32 may further include a gasket 323 connected to the toggle rod 322. When the toggle rod 322 toggles the second housing 92, the gasket 323 abuts against the second housing 92. At this time, the gasket 323 is located between the toggle rod 322 and the second housing 92. The gasket 323 is made of a flexible material or an elastic material, such as rubber, woven fabric, etc. In this way, the toggle member 32 can contact the second housing 92 through the gasket 323, and the gasket 323 plays a role in buffering and shock absorption. It should be noted that, in the process of the toggle rod 322 toggling the second housing 92, the toggle rod 322 can be stationary relative to the second housing 92, that is, the toggle rod 322 and the second housing 92 have no relative movement, so as to eliminate the wear on the second housing 92. The toggle rod 322 can also have relative movement with the second housing 92, and at this time, the gasket 323 plays a role in reducing wear. A plurality of gaskets 323 may be provided, and the plurality of gaskets 323 are arranged at equal intervals along the extending direction of the lever 322 .

[0092] It should be noted that, in an embodiment where the limit block 13 is not provided, the reset mechanism 30 can reset the second shell 92 to the folded position, which will not be described in detail here.

[0093] See also Figures 5 to 8 , Figures 5 to 8 They are all top views of the throwing-off mechanism 10 and the resetting mechanism 30 in the test device in the embodiment of the present application, wherein: Figure 5 The middle connecting seat 12 is in the first starting position, the toggle member 32 is in the second starting position, and the second housing 92 is in the ready position; Figure 6 The middle connecting seat 12 is in the first end position, the toggle member 32 is in the second start position, and the second housing 92 is in the unfolded position; Figure 7 The middle connecting seat 12 is in the first end position, and the toggle member 32 is in the second end position; Figure 8 The middle connecting seat 12 is in the first end position, the shifting member 32 is in the second end position, and the second housing 92 is in the ready position.

[0094] In some embodiments, the first rotating seat 11 can drive the connecting seat 12 to rotate in a first direction, and the second rotating seat 31 can drive the shifting member 32 to rotate in a second direction, and the first direction is opposite to the second direction. Figure 5 In the illustrated embodiment, the first direction is counterclockwise and the second direction is clockwise. The direction in which the second housing 92 rotates from the preparatory position to the deployed position is also the first direction. Thus, in the process of the toggle member 32 toggling the second housing 92 to return to the preparatory position, the rotation direction of the toggle member 32 is the same as the rotation direction of the second housing 92, which is convenient for reducing or eliminating the relative movement between the toggle rod 322 and the second housing 92, thereby reducing the wear on the second housing 92. In other embodiments, the first direction may be clockwise and the second direction may be counterclockwise, which is not limited here.

[0095] Specifically, see Figure 5 and Figure 6 The first rotating seat 11 can drive the connecting seat 12 to rotate between the first starting position and the first ending position. When the first rotating seat 11 drives the connecting seat 12 to rotate from the first starting position to the first ending position, the second shell 92 can be thrown from the preparation position to the deployment position.

[0096] See also Figure 6 and Figure 7 The second rotating seat 31 can drive the toggle member 32 to rotate between the second starting position and the second end position. When the toggle member 32 is in the second starting position, the second rotating seat 31 and the toggle member 32 avoid the second shell 92. When the second shell 92 is in the unfolded position, the second rotating seat 31 can drive the toggle member 32 to rotate from the second starting position to the second end position. Figure 8 The toggle member 32 can toggle the second housing 92 to return to the ready position during the process of rotating from the second starting position to the second ending position.

[0097] When the second housing 92 is reset, the first rotating seat 11 can drive the connecting seat 12 to reset, and the second rotating seat 31 can drive the toggle member 32 to reset. It can be understood that when the second housing 92 is reset to the preparation position, the first rotating seat 11 can drive the connecting seat 12 to reset from the first end position to the first start position, and the second rotating seat 31 drives the toggle member 32 to reset from the second end position to the second start position, so as to prepare for the next test. Figure 7 When the toggle member 32 is located at the second end position, the second housing 92 may have reached the preparatory position, or may not have reached the preparatory position and continue to rotate to the preparatory position by inertia.

[0098] Optional, such as Figure 6 When the connecting seat 12 is in the first terminal position, the rotation axis of the toggle member 32 can be close to the rotation axis of the second shell 92, or coincide with the rotation axis of the second shell 92, so as to further reduce the relative movement between the toggle member 32 and the second shell 92, thereby further reducing the wear on the second shell 92.

[0099] In some embodiments, please combine Figure 5 and Figure 6 When the second housing 92 is swung open to the unfolded position, the rotation angle of the connection base 12 is 90°-150°. It can be understood that the rotation angle of the connection base 12 between the first starting position and the first ending position is 90°-150°. This rotation angle is closer to the actual swing angle of the user in the swinging scene, so as to better restore the use scene and improve the accuracy of the test results.

[0100] Please combine Figure 6 When the toggle member 32 is in the second starting position and the second shell 92 is in the extended position, the toggle member 32 is spaced from the second shell 92 to reserve a shaking space for the second shell 92 when it is swung to the extended position, so as to avoid the second shell 92 and the toggle rod 322 from colliding during the process of swinging the second shell 92. In practical applications, the rotation angle of the toggle member 32 to abut against the second shell 92 is 20°-30°, that is, the angle between the toggle member 32 and the second shell 92 is 20°-30° when the toggle member 32 is in the second starting position. In other embodiments, when the toggle member 32 is in the second starting position, the toggle member 32 may also abut against the second shell 92, which is not limited here.

[0101] In order to facilitate the description of the positional relationship of each structure, the xyz coordinate system can be introduced, where Figures 5 to 8, the extension direction of the rotation axis of the first rotating seat 11 is the z-axis direction, the direction perpendicular to the rotation axis of the first rotating seat 11 and passing through the rotation axis of the second rotating seat 31 is the x-axis direction, and the direction perpendicular to the x-axis and the y-axis is the y-axis direction. As a specific embodiment, the z-axis direction is the gravity direction to eliminate the influence of gravity on the detection result and improve the accuracy of the detection result. Figure 5 When the connection base 12 is in the first starting position, the angle between the connection base 12 and the y-axis is 90°-150°. Figure 6 When the connection base 12 is in the first end position, the connection base 12 is parallel to the x-axis. At this time, when the second shell 92 is in the extended position, the first shell 91 and the second shell 92 are parallel to the x-axis. When the toggle member 32 is in the second starting position, the angle between the toggle member 32 and the x-axis is 20°-30°. Figure 7 When the toggle member 32 is in the second end position, the angle between the second housing 92 and the x-axis is 90°.

[0102] See also Fig. 9 , Fig. 9 It is a three-dimensional structural diagram of the test device in the embodiment of the present application under another viewing angle. In some embodiments, the shooting mechanism 20 can collect image information of the folding screen when the connecting seat 12 is in the first end position and the toggle member 32 is in the second starting position. It can be understood that when the connecting seat 12 is in the first end position and the toggle member 32 is in the second starting position, the second shell 92 is in the unfolded position, and the shooting mechanism 20 can face the folding screen at this time and collect image information of the folding screen.

[0103] As one of the embodiments, the shooting mechanism 20 includes a camera module 21, a lighting board 22 and a processor. The lighting board 22 is connected to the camera module 21, the camera module 21 is used to collect image information of the folding screen, and the lighting board 22 is used to emit light toward the folding screen to improve the clarity of the image information collected by the camera module 21.

[0104] Optionally, the shooting mechanism 20 may further include a processor, which can store the image information collected by the camera module 21 and process the image information. The processing content includes comparing the image information with the image information of qualified products to determine whether the collected image information is qualified.

[0105] Please continue reading Fig. 9 In order to improve the accuracy of the test results, the testing device may also have a temperature and humidity control mechanism 40, which is used to adjust the ambient temperature and humidity of the folding screen mobile phone 90 so that the ambient temperature and humidity meet the test conditions, thereby improving the accuracy of the test results.

[0106] See also Fig.10 , Fig.10 3D diagram of the test device in the embodiment of the present application from another perspective. In some embodiments, the test device further includes a bracket 50, and the swing mechanism 10, the reset mechanism 30, the shooting mechanism 20 and the temperature and humidity control mechanism 40 are all installed on the bracket 50. The bracket 50 supports and positions the swing mechanism 10, the reset mechanism 30, the shooting mechanism 20 and the temperature and humidity control mechanism 40, thereby ensuring the test accuracy and facilitating the assembly and transportation of the test device.

[0107] The bracket 50 includes a support seat 51, a first support plate 52, a second support plate 53 and a third support plate 54. The first support plate 52 and the second support plate 53 are both connected to the support seat 51 and are arranged opposite to each other. The third support plate 54 is connected to one end of the first support plate 52 away from the support seat 51 and extends toward the second support plate 53. At this time, a certain installation space is formed between the third support plate 54 and the support seat 51. Among them, the first rotating seat 11 and the second rotating seat 31 are both installed on the support seat 51. The rotating shaft of the first rotating seat 11 is rotatably connected to the third support plate 54. One of the two connecting rods 321 is connected to the rotating shaft of the second rotating seat 31, and the other is rotatably connected to the third support plate 54. The third support plate 54 can limit the shaking of the throwing mechanism 10 and the reset mechanism 30. The connecting seat 12 and the toggle member 32 are both located in the installation space, and the second support plate 53 avoids the connecting seat 12 and the toggle member 32. The photographing mechanism 20 is mounted on the second supporting plate 53 and faces the first supporting plate 52 . The temperature and humidity control mechanism 40 is mounted on the supporting base 51 .

[0108] It should be noted that in other embodiments, at least one of the reset mechanism 30, the temperature and humidity control mechanism 40 and the bracket 50 may not be provided, and this is not limited here.

[0109] The embodiments of the present application also provide a testing method, which is applied to the testing devices described in the above embodiments.

[0110] The test method includes:

[0111] S1, connecting the first housing to the connecting seat of the swinging mechanism;

[0112] S2. Under the set test conditions, the connecting seat is rotated by the first rotating seat until the second shell is thrown open to the unfolded position;

[0113] S3, after the second housing is swung open to the unfolded position, the connecting seat is controlled to stop rotating through the first rotating seat;

[0114] S4, after the connecting base stops rotating, collecting image information of the folding screen through the shooting mechanism;

[0115] S5, after the shooting mechanism has collected the image information, the second housing and the connecting seat are reset;

[0116] S6, performing abnormality detection on the folding screen in the image information to obtain a detection result;

[0117] S7, if the test result is qualified and the test number is not reached, execute S2 again and perform the next test;

[0118] S8. If the test result is unqualified, the electronic device is judged to be ineffective, the test is stopped, and the current test conditions and the number of tests are recorded;

[0119] S9. If the test result is qualified and the test times have been reached, the electronic device is judged to be qualified, the test is stopped, and the current test conditions and the test times are recorded.

[0120] The test method controls the connection seat to rotate by the first rotating seat to swing the electronic device to the unfolded state, and then collects the image information of the folding screen through the shooting mechanism and performs abnormal detection. When the test result is qualified and the number of tests is not reached, the next test is performed again until the test result is unqualified or the number of tests is reached, and then the test is stopped. When the test result is still qualified when the number of tests is reached, the electronic device is judged to be qualified, and the current test conditions and the number of tests are recorded, indicating that the electronic device can meet the design requirements under the current test conditions and the number of tests. When the number of tests is not reached and the test result is already unqualified, the electronic device is judged to be failed, and the current test conditions and the number of tests are recorded. The test conditions and the number of tests are the failure conditions of the electronic device, and the number of tests is the swing folding life of the electronic device under the test conditions. According to the abnormal area in the image information that causes the test result to be unqualified, the weak link or dangerous part of the electronic device under the test condition can be found. The test method can effectively simulate the scene of the user actually swinging the electronic device, and through repeated detection, the failure of the electronic device is stimulated. The test results obtained by the test method are highly accurate and consistent, efficient and convenient, filling the gap in the durability test of electronic devices under the swinging scene.

[0121] It should be noted that the qualified electronic device means that it meets the quality requirements for the electronic device. The execution order of step S5 and step S6 is not limited. In this embodiment, step S5 is executed first, and then step S6 is executed.

[0122] Before step S1, the test method further includes: setting test conditions and the number of times the electronic device is thrown away under the test conditions, and the test conditions include: the throwing away speed when the first rotating seat rotates and the temperature and humidity of the environment in which the electronic device is located. It can be understood that under the set test conditions, if the test result is qualified, S2 is executed again until the number of cycle detections reaches the number of times the electronic device is thrown away. If the test result is still qualified at this time, the electronic device is judged to be qualified. If the number of cycle detections is unqualified before reaching the number of times the electronic device is thrown away, the number of times the detection has been performed is recorded, that is, the number of detections. The number of detections is the throwing away and folding life of the electronic product under the test conditions. In this way, by setting different factors and parameters, different users and different usage environments can be better simulated, and then the swinging and folding life of the electronic device under different test conditions can be obtained, thereby improving the accuracy of the test results.

[0123] As one embodiment, the test conditions include: a first condition, a second condition and a third condition, wherein the first condition, the second condition and the third condition all include at least one of the swinging speed of the first rotating base when rotating and at least one of the temperature and humidity of the environment where the electronic device is located.

[0124] Specifically, the first condition includes: a first swing-off speed, a first temperature, and a first humidity. It can be understood that the first swing-off speed has only one speed value, the first temperature has only one temperature value, and the first humidity has only one humidity value. When the detection is performed under the first condition, it indicates that the first rotating seat rotates at the first swing-off speed, the ambient temperature is the first temperature, the ambient humidity is the first humidity, and the number of detections under the first condition is the number of swing-offs corresponding to the first condition.

[0125] The second condition includes: a second swing-off speed, a second temperature, and a second humidity. The second swing-off speed has multiple speed values, and each speed value corresponds to a number of swing-off times. It can be understood that the second swing-off speed has multiple speed values, the second temperature has only one temperature value, and the second humidity has only one humidity value. When the detection is performed under the second condition, it indicates that the first rotating seat rotates at different speed values ​​in sequence, and the corresponding number of swing-off times must be performed at each speed value. The ambient temperature is the second temperature, and the ambient humidity is the second humidity. The number of detections under the second condition is the sum of the number of swing-off times corresponding to each speed value. Among them, the second temperature is equal to the first temperature, and the second humidity is equal to the first humidity.

[0126] The third condition includes: a third swing-off speed, a third temperature and a third humidity. The third temperature has multiple temperature values, and each temperature value corresponds to a number of swing-offs. The third temperature has multiple humidity values, and each humidity value corresponds to a number of swing-offs. It can be understood that the third swing-off speed has only one speed value, the third temperature has multiple temperature values, and the third humidity has multiple humidity values. When the detection is performed under the third condition, it indicates that the first rotating seat rotates at the third swing-off speed, the ambient temperature is set to different temperature values ​​in turn, and the corresponding number of swing-offs must be executed at each temperature value. The ambient humidity is set to different humidity values ​​in turn, and the corresponding number of swing-offs must be executed at each humidity value. The number of detections under the third condition is the sum of the number of swing-offs corresponding to each temperature value and the number of swing-offs corresponding to each humidity value. Among them, the third swing-off speed can be the first swing-off speed, or it can be one of the multiple second swing-off speeds.

[0127] Among them, when testing the same electronic device, the test order of the test conditions is: first condition, second condition, third condition. That is to say, when testing the same electronic device, first test under the first condition, after the number of tests under the first condition is completed, test under the second condition, after the number of tests under the second condition is also completed, test under the third condition, until the number of tests under the third condition is also completed, then the total number of tests under the test condition is reached. The number of tests under the test condition is equal to the sum of the number of tests under the first condition, the number of tests under the second condition, and the number of tests under the third condition.

[0128] It can be understood that when setting the test conditions, the ambient temperature and the ambient humidity are first set to the first temperature and the first humidity under the first condition respectively, and the first rotating seat executes the first swinging speed under the first condition. After the first rotating seat completes the swinging times corresponding to the first swinging speed, it has completed the corresponding detection times under the first condition; thereafter, if a temperature or a humidity corresponds to multiple swinging speeds, that is, there is a second condition, then the corresponding multiple swinging speeds are all named as second swinging speeds, the temperature and humidity remain unchanged, and the temperature and humidity are respectively named as the second temperature and the second humidity, and the first rotating seat executes the second swinging speed under the second condition in turn. The first rotating seat executes different swinging times in turn at the second temperature and the second humidity. After the number of shake-off times corresponding to the second shake-off speed is completed, the corresponding number of detection times under the second condition is executed; thereafter, if one shake-off speed corresponds to multiple temperatures or multiple humidity, that is, there is a third condition, the corresponding multiple temperatures are all named as the third temperature, and the corresponding multiple humidity are all named as the third humidity. The shake-off speed remains unchanged and the shake-off speed is named the third shake-off speed. Then, the ambient temperature and ambient humidity are set to the third temperature and third humidity under the third condition respectively. The first rotating seat still executes the third shake-off speed. After the first rotating seat executes the number of shake-off times corresponding to the current third temperature and third humidity at different third temperatures and third humidities, the corresponding number of detection times under the third condition is executed.

[0129] In this way, the complex and changeable usage environment of the user can be simulated according to the above test conditions to obtain the swing and folding life of the electronic device in the usage environment, thereby enriching the usage environment and further improving the accuracy of the test results.

[0130] It should be noted that the test condition may also include only one or two of the first condition, the second condition and the third condition. In this case, the number of detections under the test condition is the sum of the number of detections under each condition. When the test condition includes two of them, the test order remains unchanged, and the first condition is executed before the second and third conditions, and the second condition is executed before the third condition, which will not be repeated here.
