[0002] In the performance testing of automotive door lock switches, the testing interface of the product must be precisely aligned with the testing head of the testing instrument to ensure the accuracy of the test results. Patent application number 201821748995.X discloses a testing instrument mounting base for automotive door lock switch performance testing. It mainly uses protective mechanisms (such as baffles or U-shaped protective plates) to cover the testing area when not in use to prevent dust accumulation. However, because the positions of the testing interfaces of different product specifications vary, manual adjustment of the product position is required during testing to achieve alignment. This process is cumbersome and inefficient. Furthermore, the testing probes are exposed to the air, and a small amount of dust will fall onto them. Especially during batch testing, prolonged testing and repeated adjustments greatly increase the time the probes are exposed to the air, making them highly susceptible to dust and impurities.

[0028] Please see Figure 1-9 The present invention provides a technical solution: a tester mounting base for testing the performance of car door lock switches, including a base plate 1, a lifting base 2 and a protective cover 3 fixed on the lifting base 2 mounted on the base plate 1, and a test probe 4 fixedly connected to the output shaft of the lifting base 2 inside the protective cover 3.

[0029] A testing platform 5 is fixedly connected to the top of the protective cover 3. A through-type testing groove 6 is provided in the middle of the testing platform 5. An adjustment mechanism is provided on the testing platform 5. The adjustment mechanism is used to adjust the testing interface of the product to be tested to the position directly above the testing probe 4.

[0030] The testing platform 5 is equipped with a protective mechanism, which is used to seal the opening at the top of the protective cover 3 and automatically open it after the product to be tested is positioned.

[0031] During operation, since different products have different detection interface positions, the product to be tested is placed on the detection platform 5. According to the specifications of the product to be tested, the adjustment mechanism is activated. The adjustment mechanism then pushes the product to be tested on the detection platform 5 so that its detection interface is directly above the detection probe 4.

[0032] After the product to be tested is positioned, the protective mechanism is activated to open the upper opening of the protective cover 3. At this time, the lifting base 2 is activated to move the detection probe 4 upward, and the detection probe 4 automatically connects with the detection interface of the product to be tested to complete the test.

[0033] After the test is completed, the lifting base 2 is activated to move the test probe 4 downward and disengage it from the test interface. Then, the protective mechanism seals the upper opening of the protective cover 3 again, which can effectively prevent dust in the air from falling onto the test probe 4 and affecting its test accuracy.

[0034] See Figure 4-7 , Figure 9 As a further embodiment of the present invention, the adjustment mechanism includes four adjustment boxes 7 distributed in the front, back, left, and right directions of the detection platform 5, and the adjustment boxes 7 are fixedly connected to the detection platform 5; a push plate 8 is slidably connected inside the adjustment box 7; a sliding groove 9 is symmetrically opened on both sides of the adjustment box 7, and a slider 10 is slidably connected inside the sliding groove 9, and a push rod 11 is fixedly connected between the two sliders 10; a driving assembly is provided inside the adjustment box 7, which is used to drive the push rod 11 to move along the sliding groove; a connecting assembly is also provided inside the adjustment box 7, which is used to elastically connect the push rod 11 and the push plate 8;

[0035] The bottom of the adjustment box 7 is provided with a second sliding groove 12, and a second slider 13 is slidably connected in the second sliding groove 12. A cylinder 14 and two limit rods 15 are provided between the second slider 13 and the push plate 8. The two ends of the cylinder 14 are fixedly connected to the second slider 13 and the push plate 8 respectively. One end of the limit rod 15 is slidably connected to the second slider 13 and the other end is fixedly connected to the push plate 8.

[0036] The drive assembly includes a limiting post 16 disposed on the back of the adjusting box 7. The limiting post 16 is fixedly connected to the base plate 1, and a sliding sleeve 17 is sleeved on the limiting post 16. The sliding sleeve 17 is slidably connected to the limiting post 16, and a second cylinder 18 is disposed between the sliding sleeve 17 and the base plate 1. The two ends of the second cylinder 18 are fixedly connected to the base plate 1 and the sliding sleeve 17 respectively. A first connecting rod 19 is symmetrically rotatably connected to both sides of the sliding sleeve 17, and the other end of the first connecting rod 19 is rotatably connected to a first slider 10 on the same side.

[0037] The connecting assembly includes a force-balancing coil spring 20 rotatably connected to the slider 13, with the outer end of the force-balancing coil spring 20 fixedly connected to the push rod 11;

[0038] During operation, after placing the product to be tested on the testing platform 5, the cylinders 14 in the four adjustment boxes 7 are activated according to the specifications of the product. When the cylinders 14 are running, they drive the corresponding push plates 8 to move within the adjustment boxes 7, thereby adjusting the distance between the push plates 8 and the product to be tested. When all four push plates 8 are adjusted to the appropriate position, the cylinders 14 are stopped. At this time, the cylinders 28 are activated. The cylinders 28 push the sliding sleeve 17 upward. The sliding sleeve 17 drives the slider 10 to move towards the product to be tested in the sliding groove through the connecting rod 19. The slider 10 drives the push rod 11 to move. The push rod 11 drives the slider 23 to move through the balancing spring 20. The slider 23 drives the push plate 8 to move through the cylinders 14.

[0039] Because the product to be tested has an irregular shape, when two opposing push plates 8 push it to the set position in this direction, the other two opposing push plates 8 need to continue pushing to push the detection interface of the product to be tested directly above the detection probe 4. Therefore, when the two opposing push plates 8 push the product to be tested to the set position in this direction, the four cylinders 18 continue to operate. The push rod 11 in this direction can then ensure that the other two opposing push plates 8 continue to push the product to be tested by stretching the balance force coil spring 20.

[0040] See Figure 1-3 , Figure 5-8 As a further embodiment of the present invention, the protective mechanism includes four baffles 21 slidably connected inside the detection platform 5, with a pull rod 22 fixedly connected to one end of the outer side of each baffle 21; a fixed ring 23 fixedly connected to four limiting posts 16 is provided above the detection platform 5, and a rotating ring 24 is rotatably connected to the bottom end of the fixed ring 23, with four arc-shaped frames 25 fixedly connected to the rotating ring 24, and the four pull rods 22 respectively having clearance fit with the four arc-shaped frames 25; a rotating assembly is provided on the fixed ring 23, which is used to drive the rotating ring 24 to rotate relative to the fixed ring 23; a trigger assembly is provided inside the adjustment box 7, which is used to trigger the operation of the rotating assembly when the product to be tested is adjusted to the detection position;

[0041] The rotating assembly includes two springs 26 arranged in a circular array on the fixed ring 23. One end of the spring 26 is fixedly connected to the fixed ring 23 and the other end is fixedly connected to the rotating ring 24. A locking block 27 is fixedly connected to the rotating ring 24 above the adjusting box 7. A locking block 28 is provided on the adjusting box 7. The locking block 27 and the locking block 28 are engaged in a locking fit.

[0042] The triggering assembly includes two symmetrically arranged sliding plates 29 on both sides of the balancing spring 20 and slidably connected to the adjusting box 7. A groove 30 is provided at the bottom of each sliding plate 29, and a slider 31 is slidably connected within the groove 30. Screws 32 are symmetrically fixedly connected to both ends of the balancing spring 20's shaft. The screws 32 are self-locking, and the slider 31 is threadedly connected to the screws 32. A sliding rod 33 is provided between the two sliding plates 29 and slidably connected to the back of the adjusting box 7. Two connecting rods 34 are fixedly connected to one end of the sliding rod 33 inside the adjusting box 7, and the other ends of the two connecting rods 34 are rotatably connected to the two sliding plates 29 respectively. A frame 35 is slidably connected to the outer part of the sliding rod 33 outside the adjusting box 7. A spring 36 connects the frame 35 and the sliding rod 33, and two limiting rods 37 are slidably connected to the frame 35. The limiting rods 37 are fixedly connected to the adjusting box 7. A locking block 28 is fixedly connected to the frame 35.

[0043] During operation, when the two opposing push plates 8 push the product to be tested to the set position in that direction, the product cannot move further in that direction, and the corresponding two push plates 8 also cannot move further. As the four cylinders 18 continue to operate, the push rods 11 in the two adjustment boxes 7 of this part begin to stretch the force-balancing springs 20. The force-balancing springs 20 begin to rotate and drive the two lead screws 32 connected to them to rotate. When the two lead screws 32 rotate, they drive the two sliders 31 to move closer to each other. The two sliders 31 then drive the two sliding plates 29 to move respectively. The two sliding plates 29 drive the sliding rods 33 to slide outward from the adjustment box 7 through the two connecting rods 34. The sliding rods 33 drive the frame 35 and the locking block 28 to move through the spring 36. The locking block 28 at this position disengages from the corresponding locking block 27. At this time, the other two locking blocks 28 and the other two locking blocks 27 remain engaged.

[0044] As the four cylinders 18 continue to operate, when the other two opposing push plates 8 push the product to be tested to the position set in that direction, the testing interface of the product to be tested is exactly above the testing probe 4. The four cylinders 18 continue to operate, and the other two blocks 28 that are engaged with the first block 27 gradually disengage from the first block 27 as described above. When all four blocks 28 disengage from the four blocks 27, the rotating ring 24 begins to rotate under the action of the spring 26.

[0045] When the rotating ring 24 rotates, it drives the four arc-shaped frames 25 connected to it to rotate. The arc-shaped frames 25 then push the pull rod 22 to move outward. The pull rod 22 drives the baffle 21 connected to it to move. The baffle 21 disengages from the detection groove 6. At this time, the lifting base 2 can be activated to drive the detection probe 4 to dock with the detection interface of the product to be tested.
