Research on the Potential Energy-Driving Car with the Function of Avoiding Fixed-Point Obstacles

An energy storage car driven by gravitational potential energy was designed. The car could avoid the fixed obstacles set on the track when running. It only uses the gravitational potential energy as power source and doesn’t need to use any other forms of power source. The overall design of the car was completed from some aspects of the steering system, energy storage system and transmission system etc. The cam mechanism is to realize steering of the car. Vortex coil spring is to realize the energy storage in the process of weight falling. Transmission system of the car is composed of fixed pulleys, gear mechanisms and the ratchet mechanisms. Experimental result shows that design of the car is reasonable. The design of the car provides guidance significance for the carbon-free car.
