[0002] The primary function of a vehicle's suspension system is to mitigate vibrations caused by uneven roads and vertical vibrations of the vehicle body due to acceleration and braking. Traditional vehicles often use oil-based shock absorbers to mitigate body vibrations. This vibration energy ultimately raises the temperature of the hydraulic oil, which is then dissipated through heat exchange between the frame and the air. The amount of electricity stored in a car corresponds to the driving distance of the electric car. People can use the vibration energy recovery system to convert the vehicle's vibration mechanical energy into electrical energy to increase the driving range. Summary of the Invention
