[0024] During specific use, first place the support frame 1 on the outside of the car door to be tested, and make the axis of the output shaft of the drive motor 4 directly above the axis of the door hinge, adjust the position of the clamp 7 through the position adjustment mechanism 6, and move the clamp 7 to directly above the door handle, and drive the load-bearing plate 3 and the clamp 7 downward under the driving action of the height adjustment cylinder 2, so that the clamp 7 hooks the door handle, and drive the drive plate 5 to swing back and forth along the arc path under the driving action of the drive motor 4, and the drive plate 5 drives the position adjustment mechanism 6 and the clamp 7 to swing back and forth along the arc path synchronously, and the clamp 7 drives the car door to perform reciprocating opening and closing actions, thereby realizing the opening and closing durability test of the car door.
[0025] It is worth noting that the clamping member 7 can be purchased directly from the market, or the structure shown in the figure can be adopted. The clamping member 7 at least includes a pull plate and a push plate arranged in parallel. When in use, the pull plate and the push plate are respectively located on the inner and outer sides of the door handle, and the opening and closing force is applied to the door through the clamping member 7.
[0026] Specifically, see Figure 2 and Figure 3 In this embodiment, the position adjustment mechanism 6 includes a protective shell 8, an adjustment motor 9 and an adjustment screw 10.

[0033] Specifically, see Figure 1 In this embodiment, a moving wheel 18 is provided on the lower surface of the supporting base plate 13, and the moving wheel 18 is a moving wheel 18 with a self-locking function. The moving wheel 18 with a self-locking function can be purchased directly from the market, so it will not be introduced in detail in this solution.
[0034] The working principle of the automobile door switch durability test device provided by the utility model is as follows:
[0035] 1. Move the support frame 1 to the outside of the car door to be tested under the action of the moving wheel 18, and make the axis of the output shaft of the driving motor 4 directly above the axis of the hinge of the car door;
[0036] 2. Start the adjusting motor 9 to drive the adjusting screw 10 to rotate. Under the driving of the adjusting screw 10 and the sliding action of the guide slide bar 11, the adjusting plate 12 is driven to move.
