Optimization method and structure of electric vehicle resonance power generation based on leverage principle

Abstract

The invention relates to a method and a structure for generating electricity by using the kinetic energy of an automobile, which belongs to the field of automobiles. A method for optimizing resonance power generation of electric vehicles based on the principle of leverage, comprising a kinetic energy generating device arranged on a hollow weight pallet with a vertical elastic system at the sprung body, characterized in that: the hollow weight pallet and the sprung The body has the same natural frequency, the spur rack is driven by the lever, the fulcrum of the lever is set on the axle, the power end of the lever bears the vibration force of the sprung body, and the resistance end of the lever drives the spur rack to be vertically fixed on the vibration guide frame The sliding rail moves up and down; during the compression and rebound strokes of the sprung body, the lever drives different spur racks respectively to drive the gears meshed by the spur racks, so that the central shaft of the generator generates continuous torque in the same direction, and is connected with the hollow The resonant force of the heavy pallet when the vehicle body vibrates is superimposed to make the generator generate electricity.

Description

technical field [0001] The invention relates to a method for generating electricity by kinetic energy of an automobile, in particular to a method for generating electricity by vibration of an electric automobile based on a lever principle. Background technique [0002] Regarding the method of generating electricity by using the kinetic energy of a car, in addition to the recovery of kinetic energy when the car brakes, the recovery and utilization of the kinetic energy generated in the vertical direction of the vibration when the car is running, the Chinese patent application No. 201310132727.0 "A Application of Frequency Resonance Based on the method and structure of automobile kinetic energy power generation", it is proposed that the sprung body with a vertical elastic system vibrate freely at its natural frequency, and the sprung body as a support, with the same or similar natural frequency, is also set If there is an elastic system in the vertical direction, the hollow he...

Problems solved by technology

This scheme adopts the vibration conduction between multiple elastic systems to capture the vibration of the vehicle body. The power to drive the central axis of the generator to rotate mainly comes from the vibration of the sprung vehicle body caused by the excitation of the road surface when the electric vehicle is driving. On the one hand, the flat road will make the sprung vehicle body The amplitude becomes smaller. On the other hand, the bumpy road surface will cause the sprung body to have vibration suppression requirements. Although the traditional shock absorber or damping leaf spring suppresses the vibration of the body through frictional damping, it wastes vibration energy; In actual installation, the setting requirements of the pre-tightening tension spring are relatively high and complicated. Therefore, how to enhance the capture efficiency of the vibration energy of the vehicle body, simplify the method of overcoming the starting torque of the generator, and eliminate the waste of frictional heat energy by the traditional vibration damping device has not yet been updated. perfect solution
