Problems solved by technology
[0002] In the existing underground parking garage, the deceleration of the car mainly depends on the manual brake and the collision between the car and the ordinary speed bump, so that the kinetic energy of the car is reduced and the deceleration is realized. The scientific research on deceleration kinetic energy power generation is gradually increasing. It mainly uses mains power supply, and there is no example of combining the technology of converting the impulse acting on the buffer deceleration zone into electric energy with the ambient lighting of the parking lot.
