Description

Technical Field

[0001] The present invention relates to the technical field of energy recovery, and more particularly to a vehicle vibration energy recovery system and method. Background Art

[0002] At present, when vehicles, especially heavy vehicles, are moving, they will generate vibrations of different frequencies due to reasons such as ground conditions and internal excitation of the vehicle body, and these vibration energies will eventually be dissipated in the form of heat energy. This type of vibration will lead to multiple consequences: first, the vibration of the vehicle will generate additional loads and deformations on the vehicle body structure and load-bearing objects, which is not conducive to the fatigue life of the vehicle equipment; second, this type of vibration will increase the energy consumption demand of the vehicle equipment; finally, the vibration of the vehicle will reduce the comfort of the driver.

[0003] However, some vehicles have added flexible support modules, which can be used to reduce vehicle vibration and improve driving comfort. However, such support modules are mainly used in small household vehicles, not heavy vehicles, and cannot significantly reduce vehicle energy consumption or recover vibration energy.

[0004] Therefore, how to provide a vehicle vibration energy recovery system that can solve the above problems is an issue that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of this, the present invention provides a vehicle vibration energy recovery system and method, which can reduce energy consumption while smoothing the vehicle vibration peak and improving driving comfort.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0030] S1: When the vehicle passes through a bumpy road section, the air bag module generates relative movement to generate suction and compression actions.

[0031] The compressed pressure gas is input into the atmospheric pressure gas storage tank through the gas transmission pipeline;
