Description

TECHNICAL FIELD

[0002] New energy development and utilization are paid more and more attention to. In recent years, as a green traffic tool with a broad development prospect, the electric vehicle will be popularized at an extremely fast speed in the future, and the market prospect in the future is huge. At present, the Chinese government actively promotes the application and development of new energy vehicles. As important supporting infrastructure for the development of electric vehicles, the charging station has very important social and economic benefits. A movement of building electric vehicle charging / exchanging stations has been carried out in the whole country.

[0003] The existing public number: CN118876769A, an intelligent charging pile with impact early warning and automatic protection, comprises a shell, and electrical elements are installed in the shell. The position of the vehicle is monitored by the distance sensor, and the alarm volume of the buzzer alarm is increased according to the real-time distance. When a collision occurs by accident, the push rod on one side will squeeze the spring to absorb the slight impact force when the slight impact of the angle protection frame and the protection plate is received. When a strong collision occurs, the speed signal transmitter and the speed signal receiver monitor the speed of the collision and control the opening of the modular air bag in the corresponding direction, and the circuit controller cuts off the current of the power cable, protects the electrical elements, and the modular air bag can be quickly replaced after use, reducing the cost of use and replacement.
