Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] like Figures 1 to 6 As shown, in an embodiment of the present invention, an electrical performance test device for a vehicle-mounted touch display module includes a test device body 1, a test box 2 is installed on the outside of the test device body 1, and a fixing component is provided on the top of the test box 2;

[0035] Among them, the fixed component includes a support frame 3 arranged at the top of the detection box 2, and two support frames 3 are symmetrically arranged. The two support frames 3 are both fixedly connected to the detection box 2. One side of the top of the two support frames 3 is installed with a mounting plate 4 through a rotating component. Two fixing plates 5 are installed on one side of each mounting plate 4. Fixed pressure rods 7 are evenly installed inside each fixing plate 5. One end of the fixed pressure rod 7 is fixedly connected to the limiting plate 8, and the limiting plate 8 is slidably installed inside the fixing plate 5. A spring 9 is installed between the limiting plate 8 and the fixing plate 5. The end of the fixed pressure rod 7 away from the limiting plate 8 is fixedly connected to the air cushion 6. The air cushion 6 is fixedly installed on one side of the fixing plate 5, and an inflation component is arranged inside the fixing plate 5.

[0036] The surface of the air cushion 6 is elastic, i.e. rubber, and has good elasticity and wear resistance;

[0037] When conducting an electrical performance test on a vehicle-mounted touch display module, the vehicle-mounted touch display module is first placed between two sets of fixing plates 5. The elastic potential energy of the spring 9 causes the fixing pressure rod 7 to drive the air cushion 6 to fit the surface of the vehicle-mounted touch display module. The two sets of fixing plates 5 clamp and fix the two sides of the vehicle-mounted touch display module. Then, the electrical performance test of the vehicle-mounted touch display module is performed using the test device body 1.

[0038] There are multiple fixed pressure rods 7 evenly arranged, and multiple fixed pressure rods 7 contact multiple points on the surface of the vehicle-mounted touch display module. They can not only fix the flat vehicle-mounted touch display module, but are also suitable for the curved vehicle-mounted touch display module, preventing the vehicle-mounted touch display module from displacement or shaking during the test, thereby affecting the stability of the test data and improving the accuracy and credibility of the test results.

[0039] like Figure 2 and Figure 3 As shown, the mounting plate 4 is internally slidably connected to a slider 26, which is fixedly mounted on one side of the fixing plate 5. The fixing plate 5 is internally threadedly connected to a first threaded rod 11, and the top of the first threaded rod 11 is fixedly mounted with a first rotating block 10.

[0040] After the vehicle-mounted touch display module is placed between the two sets of fixing plates 5 for pre-fixation, the first rotating block 10 is rotated. The rotation of the first rotating block 10 drives the rotation of the first threaded rod 11. When the first threaded rod 11 rotates, it drives one of the two sets of fixing plates 5 to move downward, thereby deepening the fixation of the vehicle-mounted touch display module and facilitating its firm fixation.

[0041] like Figure 4 、 Figure 5 and Figure 6 As shown, the inflation component includes a second threaded rod 14 rotatably mounted inside the fixed plate 5, the outer wall of the second threaded rod 14 is threadedly connected to a movable plate 17, one side of the movable plate 17 is fixedly connected to a connecting rod 18, and an end of the connecting rod 18 away from the movable plate 17 is fixedly mounted with a push plate 19, and the push plate 19 is slidably mounted inside the air storage chamber 20, and the air storage chamber 20 is opened inside the fixed plate 5, and one end of the air storage chamber 20 is connected to the air cushion 6.

[0042] One of the two sets of fixing plates 5 is threadedly connected to the first threaded rod 11, and the other fixing plate 5 is rotatably connected to the first threaded rod 11;

[0043] One of the second threaded rods 14 in the two sets of fixing plates 5 is fixedly connected to the connecting shaft 16 , and the other second threaded rod 14 is fixedly connected to the second gear 13 ;

[0044] When the first threaded rod 11 rotates, the rotation of the first threaded rod 11 drives the rotation of the first gear 12, and the rotation of the first gear 12 drives the rotation of the second gear 13. The rotation of the second gear 13 drives the rotation of one of the second threaded rods 14 and the first rotating shaft 15. The rotation of the first rotating shaft 15 drives the rotation of the connecting shaft 16. The rotation of the connecting shaft 16 drives the rotation of the other second threaded rod 14, so that the second threaded rods 14 inside the two fixed plates 5 rotate at the same time. The rotation of the second threaded rod 14 drives the movement of the movable plate 17. The movement of the movable plate 17 drives the movement of the connecting rod 18. The movement of the connecting rod 18 drives the movement of the push plate 19. When the push plate 19 moves, the gas inside the air storage chamber 20 is squeezed into the air cushion 6. The air cushion 6 expands and is located on both sides of the vehicle-mounted touch display module, providing stable support and fixing effects.

[0045] like Figure 5 and Figure 6 As shown, one of the fixed plates 5 is rotatably connected to the inside of a first gear 12, the first gear 12 is fixedly mounted on the bottom end of the first threaded rod 11, the bottom end of the first threaded rod 11 is fixedly connected to the first gear 12, the first gear 12 is rotatably mounted on the inside of one of the fixed plates 5, one side of the first gear 12 is meshedly connected to the second gear 13, the top end of the second gear 13 is fixedly connected to the first rotating shaft 15, the inside of the first rotating shaft 15 is installed with a connecting shaft 16, and the connecting shaft 16 is mounted on the side wall of the other fixed plate 5.

[0046] like Figure 6 As shown, the first rotating shaft 15 is slidably connected to the connecting shaft 16 .

[0047] When the two fixing plates 5 move relative to each other, the connecting shaft 16 slides inside the first rotating shaft 15 , and the rotation of the first rotating shaft 15 drives the rotation of the connecting shaft 16 .

[0048] like Figure 6 As shown, the inner wall diameter of the first gear 12 is ten N times the inner wall diameter of the second gear 13 , and N is a positive integer.

[0049] The first gear 12 rotates one circle and drives the second gear 13 to rotate ten N circles. The second gear 13 rotates faster, so that the push plate 19 can push more gas into the air cushion 6.

[0050] like Figures 1 to 6 As shown, a buffer pad 21 is installed on the side of the air cushion 6 away from the fixing plate 5 .

[0051] The buffer pad 21 is configured to be made of soft material, such as a silicone pad or a foam pad, to reduce direct contact and disperse pressure, thereby avoiding scratching the vehicle-mounted touch display module.

[0052] like Figure 2 and Figure 3As shown, the rotating assembly includes a second rotating shaft 22 fixedly mounted on one side of the mounting plate 4, and one end of the second rotating shaft 22 away from the mounting plate 4 is embedded in the interior of the support frame 3, and the second rotating shaft 22 is rotationally connected to the support frame 3 through a transmission assembly.

[0053] During the electrical performance test of the vehicle-mounted touch display module, the mounting plate 4 can be driven to rotate by the transmission structure. The rotation of the mounting plate 4 drives the two sets of fixing plates 5 to rotate while clamping the vehicle-mounted touch display module, which facilitates the detection of the rotation angle of the vehicle-mounted touch display module and improves the convenience of operation for the staff.

[0054] like Figure 2 and Figure 3 As shown, the transmission assembly includes a worm 23 fixedly mounted on the outer wall of the second rotating shaft 22, one side of the worm 23 is meshedly connected with a worm wheel 24, and the top of the worm wheel 24 is fixedly mounted with a second rotating block 25, which is arranged above the support frame 3.

[0055] When the vehicle-mounted touch display module needs to rotate an angle, the second rotating block 25 is rotated. The rotation of the second rotating block 25 drives the rotation of the worm gear 24. The rotation of the worm gear 24 drives the rotation of the worm 23. The rotation of the worm 23 drives the rotation of the second rotating shaft 22. The rotation of the second rotating shaft 22 drives the rotation of the mounting plate 4. The worm 23 and the worm gear 24 are self-locking, which can improve the stability during rotation.

[0056] A method for testing an electrical performance test device for a vehicle-mounted touch display module comprises the following steps:

[0057] S1: When conducting an electrical performance test on a vehicle-mounted touch display module, the vehicle-mounted touch display module is first placed between two sets of fixing plates 5. The elastic potential energy of the spring 9 causes the fixing pressure rod 7 to drive the air cushion 6 to pre-fix the surface of the vehicle-mounted touch display module.

[0058] S2: Then, the first rotating block 10 is rotated. The rotation of the first rotating block 10 drives the rotation of the first threaded rod 11. When the first threaded rod 11 rotates, it drives one of the fixing plates 5 to move downward, thereby reducing the distance between the two fixing plates 5 to fix the vehicle-mounted touch display module;

[0059] S3: When the first threaded rod 11 rotates, the rotation of the first threaded rod 11 drives the rotation of the first gear 12, the rotation of the first gear 12 drives the rotation of the second gear 13, the rotation of the second gear 13 drives the rotation of one of the second threaded rods 14 and the first rotating shaft 15, the rotation of the first rotating shaft 15 drives the rotation of the connecting shaft 16, the rotation of the connecting shaft 16 drives the rotation of the other second threaded rod 14, so that the second threaded rods 14 inside the two fixed plates 5 rotate at the same time, the rotation of the second threaded rod 14 drives the movement of the movable plate 17, the movement of the movable plate 17 drives the movement of the connecting rod 18, the movement of the connecting rod 18 drives the movement of the push plate 19, and when the push plate 19 moves, the gas inside the air storage chamber 20 is squeezed into the air cushion 6, and the air cushion 6 expands and is located on both sides of the vehicle-mounted touch display module for stable fixation;

[0060] S4: During the test, the second rotating block 25 can be rotated. The rotation of the second rotating block 25 drives the rotation of the worm gear 24. The rotation of the worm gear 24 drives the rotation of the worm 23. The rotation of the worm 23 drives the rotation of the second rotating shaft 22. The rotation of the second rotating shaft 22 drives the rotation of the mounting plate 4.
