[0031] Reference Figure 1-5 The utility model provides a specific implementation method: a travel switch controller for an aluminum door of a power generation vehicle, comprising a fixing plate 1, a box body 2 is fixedly connected to the front end of the fixing plate 1, a pin shaft 3 is rotatably connected to the upper part of the front end of the fixing plate 1, and a shift block 5 is fixedly connected to the pin shaft 3 through a fixing bolt 4, and an elastic washer 6 and a flat washer 7 are fixedly sleeved at the front of the outer wall of the fixing bolt 4, and the fixing bolt 4 is a full-thread hexagonal head bolt. By providing an elastic washer 6 and a flat washer 7, and making the fixing bolt 4 a full-thread hexagonal head bolt, the shift block 5 can be better fixed, so that It can be used normally. The front end of the fixed plate 1 is fixedly connected to the travel switch body 11 by two fixing screws 10. The two fixing screws 10 are cross-slot pan head screws. By using the two fixing screws 10 as cross-slot pan head screws, the travel switch body 11 can be stably fixed on the fixed plate 1. A rubber double-sided protective coil 12 is fixedly provided at the lower part of the side of the box body 2 away from the first movable groove 9. By providing the rubber double-sided protective coil 12, the wires of the travel switch body 11 can be effectively protected for stable use.

[0032] A torsion spring 8 is fixedly connected to the front end of the fixed plate 1 near the shift block 5, and a first movable groove 9 is provided at the upper part of one side of the box body 2. The shift block 5 is movably arranged in the first movable groove 9. By movably setting the shift block 5 in the first movable groove 9, the effective rotational movement of the shift block 5 can be achieved to prevent the box body 2 from blocking the shift block. A second movable groove 13 is provided at the rear end of the shift block 5. The torsion spring 8 is movably arranged in the second movable groove 13. By movably setting the torsion spring 8 in the second movable groove 13, the torsion spring 8 can be ensured to smoothly contract and extend. The two ends of the torsion spring 8 are respectively fixedly connected to the box body 2 and the shift block 5. By fixing the two ends of the torsion spring 8 to the box body 2 and the shift block 5, the reset of the shift block 5 can be controlled, so that the travel contact pops up, the contacts of the travel switch body 11 are disconnected, and the power is cut off.

[0033] Working principle: The device is provided with an elastic washer 6 and a flat washer 7, which can better fix the shift block 5 and make it stable for use. When the lock is closed, the shift block 5 rotates and collides with the travel contact to achieve power supply. When the lock is opened, the elastic force of the torsion spring 8 resets the shift block 5 to rotate in the opposite direction. At this time, the travel contact can be bounced up, and the contacts of the travel switch body 11 are disconnected to achieve power off. In this process, each component is flexible and free of jamming. Through the use of existing vehicles, this device can effectively control the door opening and closing signals to ensure the safety performance of vehicle driving. At the same time, the rubber double-sided protective coil 12 can be provided to effectively protect the wires of the travel switch body 11 to improve the use effect.
