[0028] In the embodiments of the present application, the words such as "exemplary" or "for example" are used to mean serving as an example, instance, or illustration. Any embodiment or design presented as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or advantageous than other embodiments or design solutions. Rather, the use of the words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner.

[0029] The embodiments of the present application provide a testing device 100 for testing a display screen 200, such as Figure 1 as shown, Figure 1 The structural schematic diagram of the testing device 100 provided by the embodiments of the present application is shown. The testing device 100 includes a base 1, a support 2, a measuring device 3 and a support member 4. The support 2 is arranged on the base 1. The measuring device 3 is arranged on the support 2. The support member 4 is arranged on the base 1, and is used to adjust the placement angle of the display screen 200. Figure 2 The support 2 is at least partially rotatable, and the measuring device 3 is arranged on the rotatable part of the support 2.

[0030] In actual application, the support 2 is arranged on the base 1, and the base 1 provides a mounting position for the support 2. The measuring device 3 is arranged on the support 2, and the support 2 provides a mounting position for the measuring device 3. The support member 4 is arranged on the base 1, and the base 1 provides a mounting position for the support member 4. The support 2 is at least partially rotatable, and the measuring device 3 is arranged on the rotatable part of the support 2 and rotates with the rotatable part of the support 2.

[0031] When the testing device 100 needs to test the display screen 200 with complex shape, the angle of the measuring device 3 can be adjusted by rotating the support 2, and the placement angle of the display screen 200 can be adjusted by the support member 4. The combination of the two ensures that the testing area of the display screen 200 is perpendicular to the measuring device 3, so as to obtain correct testing result.

[0032] It can be understood that the support member 4 can adjust the placement angle of the display screen 200. When different display screens 200 with different shapes and sizes need to be tested, different support members 4 need to be replaced to ensure that the support member 4 can actually adjust the angle of the display screen 200.

[0033] For example, in order to ensure that the test results and actual use remain consistent, the display screen 200 should be fixed to the base according to the actual installation angle for testing.

[0034] For example, the base 1 further comprises a plurality of fixing holes 11, and the base 1 is fixed through the fixing holes 11. Fixing the base 1 can ensure that the test device 100 does not move under force during the test of the display screen 200, affecting the test results of the display screen 200.

[0035] For example, the base 1 further comprises a first limiting portion 12 and a second limiting portion 13. The display screen 200 is fixed to the base 1 through the first limiting portion 12 and the second limiting portion 13. Fixing the display screen 200 can ensure that the display screen 200 does not move under force during the test, affecting the test results.

[0036] In some embodiments, as shown in Figure 1 The support 2 comprises a main support 21 and a secondary support 22. The main support 21 is arranged on the base 1. The secondary support 22 is rotationally connected with the main support 21, and the measuring device 3 is arranged on the secondary support 22.

[0037] In actual application, the main support 21 is arranged on the base 1 to provide installation positions and installation spaces for the secondary support 22 and the measuring device 3. The secondary support 22 is rotationally connected with the main support 21, and the measuring device 3 is arranged on the secondary support. When it is necessary to adjust the angle of the measuring device 3, the secondary support 22 is rotated to adjust the angle of the measuring device 3 relative to the display screen 200.

[0038] It can be understood that the rotatable part of the secondary support 22 can be fixed relative to the main support 21, and the secondary support 22 is fixed after being rotated to a suitable position, so as to avoid rotation of the secondary support 22 under force during the test, affecting the test results.

[0039] For example, the main support 21 is 2, which are arranged on both sides of the base 1, and the two ends of the secondary support 22 are connected between the two main supports 21, and the main body of the secondary support 22 is rotatable relative to the main support 21.

[0040] For example, a plurality of first connecting holes are formed on the base 1, and a plurality of second connecting holes are formed on the main support 21. Fasteners such as screws and rivets are used to pass through the second connecting holes to arrange the main support 21 on the base 1. It can be understood that the installation position of the main support 21 on the base 1 can be changed, and the distance between the measuring device 3 and the display screen 200 can be adjusted by adjusting the installation position of the main support 21 on the base 1.

[0041] In some embodiments, as shown in Figure 1 Along the extension direction of the secondary support 22, a plurality of installation portions 221 are formed on the secondary support 22, and the measuring device 3 is detachably connected to the installation portions 221.

[0042] In actual application, the measuring device 3 is detachably connected to the mounting portion 221. In order to test each position of the display screen 200 more conveniently, the measuring device 3 needs to be frequently changed in position, so the testing device 3 and the auxiliary support 22 are set to be detachably connected. A plurality of mounting portions 221 are arranged in the extension direction of the auxiliary support 22, and the testing device 3 can be moved on the auxiliary support 22, so as to test each position of the display screen 200.

[0043] For example, the auxiliary support 22 can be provided with a linear structure such as a sliding rail, a screw rod, a guide rail, etc. The linear structure is arranged in the extension direction of the auxiliary support 22. The measuring device 3 is arranged on the linear structure, and the position of the measuring device 3 on the auxiliary support 22 can also be adjusted.

[0044] In some embodiments, the mounting portion 221 is a sliding groove. The extension direction of the sliding groove is perpendicular to the extension direction of the auxiliary support 22 and parallel to the base 1.

[0045] In actual application, in order to speed up the connection speed between the measuring device 3 and the auxiliary support 22 and improve the testing efficiency of the display screen 200, the mounting portion 221 is set to be a sliding groove. The mounting of the sliding groove is relatively simple, and does not need complex mounting tools and skills, so it can be quickly put into use.

[0046] It can be understood that the mounting portion 221 is set for the quick connection between the measuring device 3 and the auxiliary support 22, and other quick connection modes such as a screw thread, magnetic attraction, and a screw can be used instead.

[0047] In some embodiments, as shown in Figure 1 The measuring device 3 includes a measuring gauge 31 and a contact piece 32. The measuring gauge 31 is arranged on the auxiliary support 22. The contact piece 32 is connected with the measuring gauge 31 and used to abut against the display screen 200.

[0048] In actual application, the measuring gauge 31 is arranged on the auxiliary support 22. The contact piece 32 is connected with the measuring gauge 31 and abuts against the display screen 200. When the display screen 200 is subjected to a force, the contact piece 32 and the display screen 200 relatively displace, and the relative displacement amount of the contact piece 32 and the display screen 200 can be read through the measuring gauge 31.

[0049] For example, the measuring gauge 31 is a digital caliper. The main function of the measuring gauge 31 is to measure the relative displacement between the contact piece 32 and the display screen 200. The display screen of the digital caliper can directly display the measurement result, the test result is clear, and the test data can be stored to avoid forgetting to record the test result in the testing process. Of course, the measuring gauge 31 can also be a mechanical caliper.

[0050] Exemplarily, the contact member 32 is a ball head. The ball head can better adapt to curved surfaces and reduce measurement errors. The ball head can more stably contact the test display screen 200 and reduce errors caused by improper operation. The ball head can better test display screens with complex shapes or curved surfaces and reduce test errors caused by poor contact between the contact member 32 and the display screen 200.

[0051] It can be understood that the contact member 32 is connected to the measurement end of the measuring meter 31, and the screw of the digital caliper can fix the contact member 32. The connection of the contact member 32 and the measuring meter 31 can directly feed back the relative displacement of the contact member 32 and the display screen 200 to the measuring meter 31. Of course, in order to ensure that the contact member 32 can be vertically arranged relative to the display screen 200, the contact member 32 and the measuring meter 31 are arranged in a rotatable connection. In the actual operation process, the auxiliary support 22 is first rotated to the position where the display screen 200 needs to be tested, and then the contact member 32 is rotated to make the contact member 32 perpendicular to the test position of the display screen 200.

[0052] It can be understood that the contact member 32 can be fixed relative to the measuring meter 31. When the contact member 32 is rotated to the appropriate position, the contact member 32 is fixed to avoid the contact member 32 from being rotated under stress during the test, which affects the test result.

[0053] In some embodiments, as shown in Figure 1 The test device 3 further includes a clamping assembly 33. The clamping assembly 33 is detachably connected with the auxiliary support 22. Part of the measuring device 3 is clamped between the clamping assembly 33 and the auxiliary support 22.

[0054] In actual application, in order to prevent the measuring device 3 from being offset or falling off the auxiliary support 22 under stress, the clamping assembly 33 is arranged. Part of the measuring device 3 is clamped between the clamping assembly 33 and the auxiliary support 22, and the clamping assembly 33 can limit the measuring device 3.

[0055] Exemplarily, the clamping assembly 33 can also be a quick fixing assembly such as a screw, a pressing plate, and magnetic attraction, which fixes the measuring device 3 to the auxiliary support 22 to avoid the measuring device 3 from being offset or falling off the auxiliary support 22 under stress.

[0056] In some embodiments, as shown in Figure 1 The clamping assembly 33 includes a fixing member 331 and a first protective member 332. The fixing member 331 is detachably connected with the auxiliary support 22. The first protective member 332 is located on the side of the fixing member 331 close to the measuring device 3 and abuts against the measuring device 3.

[0057] In practical application, the clamping assembly 33 fixes the measuring device 3 into the mounting portion 221 of the auxiliary support 22 by the fixing member 331. In order to prevent the fixing member 331 and the measuring device 3 from rubbing against each other and damaging the measuring device 3, the first protective member 331 is arranged between the fixing member 331 and the measuring device 3. The first protective member 331 can protect the measuring device 3 and also can enhance the fixing effect of the fixing member 331 on the measuring device 3.

[0058] For example, the fixing member 331 is made of metal. The metal has strong mechanical properties and high deformation resistance, and can withstand a large force. In this way, the fixing member 331 is prevented from being deformed when the clamping assembly 33 is stressed, so that the clamping assembly 33 is not disengaged and the testing of the testing device 100 is affected. The first protective member 332 is made of silica gel. The silica gel can withstand high and low temperatures, and has softness and elasticity. In this way, the friction between the measuring device 3 and the clamping assembly 33 is avoided.

[0059] Of course, the first protective member 332 can also be sponge, rubber or other materials that have softness and elasticity.

[0060] In some embodiments, as shown in Figure 1 The main support 21 is provided with a mounting groove 211. The extension direction of the mounting groove 211 is perpendicular to the extension direction of the auxiliary support 22 and parallel to the base 1. The two ends of the auxiliary support 22 are slidingly connected in the mounting groove 211.

[0061] In practical application, the main support 21 is provided with the mounting groove 211, and the two ends of the auxiliary support 22 are slidingly connected in the mounting groove 211. The measuring device 3 is arranged on the auxiliary support 22 and can rotate with the auxiliary support 22 to adjust the height of the measuring device 3. At the same time, the two ends of the auxiliary support 22 are slidingly connected on the main support 21. By sliding the auxiliary support 22, the angle of the measuring device 3 relative to the main support 21 can be adjusted, and the range that can be tested by the measuring device 3 is expanded.

[0062] Of course, the main support 21 can be provided with a slide rail, a guide rail or other structures, and the two ends of the auxiliary support 22 are slidingly connected in the slide rail or the guide rail. In this way, the angle of the measuring device 3 relative to the main support 21 can also be adjusted.

[0063] It can be understood that the two ends of the auxiliary support 22 in the sliding groove can be fixed relative to the main support 21. When the auxiliary support 22 is moved to a suitable position, the auxiliary support 22 is fixed to avoid movement of the auxiliary support 22 during testing and affect the test result.

[0064] In some embodiments, as shown in Figure 1 The testing device 100 further comprises a pushing mechanism 5. The pushing mechanism 5 is used to push the display screen 200 so that the display screen 200 contacts the measuring device 3.

[0065] In practical application, the display screen 200 is fixed to the base 1, and the contact 32 of the measuring device 3 abuts against the display screen 200. The pushing mechanism 5 can push the display screen 200, so that the contact 32 is relatively displaced from the display screen 200, and the measuring meter 31 can record the displacement data, thereby completing the test of the display screen 200.

[0066] For example, the test device 100 further comprises an electric push-pull force meter. The electric push-pull force meter can accurately provide the pushing and pulling force, and overcomes the problem that the pushing and pulling force of a person cannot be accurately controlled, and the person is tired after repeated force application. Of course, the electric push-pull force meter can also be replaced by a hydraulic piston, a pneumatic piston, or a mechanical spring push-pull force meter.

[0067] For example, as shown in Figure 2 and Figure 3 , the pushing mechanism 5 can be arranged in front of and behind the display surface of the display screen 200, and respectively test the front and rear surfaces of the display surface of the display screen 200.

[0068] In some embodiments, as shown in Figure 2 , the pushing mechanism 5 comprises a pushing member 51 and a second protective member 52. The second protective member 52 is located on one side of the pushing member 51 and connected with the pushing member 51.

[0069] In practical application, in order to prevent the pushing member 51 and the display screen 200 from colliding with each other and damaging the display screen 200, the second protective member 52 is arranged between the pushing member 51 and the display screen 200, and the second protective member 52 can protect the display screen 200.

[0070] For example, the pushing member 51 is made of metal, which has strong mechanical properties and high deformation resistance, and can withstand a large force to avoid deformation of the pushing member 51 due to force. The second protective member 52 is made of silica gel, which can withstand high and low temperatures, and has softness and elasticity, so as to avoid direct collision between the pushing member 51 made of metal and the display screen 200.

[0071] Of course, the second protective member 52 can also be sponge or rubber, which has softness and elasticity.

[0072] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
