Description

technical field [0001] The invention belongs to the technical field of power generation devices, and relates to a power generation device for automobile shock absorbers. Background technique [0002] Permanent magnet linear power generation is a technology for special linear generators. Compared with traditional rotary power generation, permanent magnets are used instead of electric excitation, which makes the power generation structure simpler and electrical control easier. Permanent magnet linear generators are small in size, light in weight, low in loss and high in efficiency, and have good application prospects in the field of micro motors. Especially for occasions where the power source is in the form of oscillating motion, since the motion conversion device is omitted, the mechanical energy can be directly converted into electrical energy, and the power generation efficiency becomes higher. The shock absorber power generation structure adopted in the present invention...

AI Technical Summary

Problems solved by technology

This is because the size of the shock absorber is small, and the existing linear power generation equipment is difficult to meet the requirements of direct installation. At the same time, because the vibration of the shock absorber has great randomness, the electric energy recovered through the power generation structure fluctuates greatly, and the voltage Dramatic changes and many pulse signals

If the recovered electric energy is directly output, it will bring a great impact to the battery and affect the life of each component
