Description
Technical Field
The invention belongs to the technical field of automobile shock absorption and energy conservation, and particularly relates to a plate spring shock absorber power generation mechanism based on ball matching.
Background
At present, automobile suspensions are devices for elastically connecting a frame and an axle in an automobile. It is composed of shock-absorbing spring, guide mechanism and shock absorber, and is mainly aimed at relaxing the impact transferred from uneven road surface to vehicle frame so as to raise the comfortability of riding.
When the shock absorber passes through an uneven road surface, the shock absorbing spring is used for filtering the shock of the road surface, but the shock absorbing spring can also do reciprocating motion, and the shock absorber which is arranged in parallel with the shock absorbing spring is mainly used for inhibiting the shock when the spring rebounds after absorbing the shock and the impact from the road surface. In order to damp vibration, most of shock absorbers adopted in an automobile suspension system are hydraulic piston open-arm shock absorbers, and the working principle is that when the frame (or the automobile body) and an axle vibrate and move relatively, a piston in each shock absorber moves up and down, and oil in each shock absorber cavity repeatedly flows into the other cavity from one cavity through different pores.
Under normal circumstances, this shock energy is not converted or stored in a timely manner and is wasted. With the popularization of automobile use, more and more energy is wasted.
The suspension system in the current market still stays in a simple buffering and vibration absorbing function, and does not provide a good technical solution for converting mechanical energy into other energy.
The invention designs a plate spring damper power generation mechanism based on ball matching to solve the problems.
