Problems solved by technology

[0002] At present, most buses adopt the design of the inner swing door, which is simple in structure and easy to use, but the most prominent problem is that the control of the inner swing door is controlled by a total air pump. The principle is that the car engine is equipped with an air compressor. , when the engine is working, the air compressor is also working. The outlet of the air compressor is connected to the air storage tank. The air storage tank has a safety valve. When the pressure in the tank exceeds a certain pressure, the safety valve will automatically open. There is a certain amount of air and a certain pressure, and the air source for opening and closing the door comes from the air storage tank. During the conduction process, insufficient air pressure may cause the door to fail to open, which wastes the time of passengers, and an air pump is controlled, and its own pressure is relatively high. Damage If there is no backup, the door cannot be opened
