Problems solved by technology

[0003] Through the method of frequency resonance, the vibration energy of the vehicle body can be absorbed to generate electricity. However, there are still sudden bumps in the driving process of electric vehicles. For such sudden bumps, the method of frequency resonance cannot completely solve the problem.

The traditional vehicle body vibration suppression is to use the vibration energy of the vehicle body to generate frictional damping and heat dissipation through the shock absorber or the vibration damping plate spring. It will reduce the conversion efficiency of vibration energy when it is applied to the car equipped with the frequency resonance vibration energy power generation device.
