Abstract

The invention provides an automobile inertial energy piezoelectric acquisition device, belonging to the technical field of energy acquisition. Includes a base and a piezoelectric beam, hollow rectangular bearings are uniformly distributed along the circumference of the disc-shaped base, the lower end of the piezoelectric beam is fixed with the upper surface of the hollow rectangular support, The inner side of the upper part of the piezoelectric beam is provided with a first magnet, the center of the base is provided with a cylindrical base, the center of the cylindrical base is provided with an arc-shaped groove, the semi-circular ball is matched with the base through the arc-shaped groove, the small end of the cone-shaped sleeve with the diameter of the upper large and lower small is fixed with the plane of the semi-circular ball, and the upper edge of the cone-shaped sleeve is provided with a second magnet. It can effectively collect the inertial kinetic energy of the acceleration and deceleration of the automobile and the turning driving process, and has the advantages of low system cost, simple structure, no need to refit the automobile, multi-direction and so on.

Description

technical field [0001] The invention belongs to the technical field of energy harvesting devices. Background technique [0002] The automobile industry is developing rapidly, and the number of automobiles in the world continues to increase. The energy system and sensor application of automobiles have attracted more and more attention from all walks of life. Most of the energy sources of automobiles rely on fossil fuels or electric energy, but only a part of the energy is used for the useful motion of the car, and most of the energy is consumed by frictional heat, vibration, inertia, etc. during the driving process of the car. With the gradual depletion of non-renewable fossil energy sources, the utilization of various new energy sources and energy harvesting have attracted more and more attention from all walks of life. Modern automobiles are becoming more and more intelligent, and a large number of sensors are used in automobile driving detection to provide drivers with i...
