The air pressure of the shock absorber not only affects the comfort of the driver and passengers, but also has a significant impact on the safety of the vehicle and personnel. Generally, the higher the air pressure, the better the performance of the shock absorber. Traditional shock absorbers are inflated from the guide end of the shock absorber. The air pressure of the gas injected is relatively low and the internal air pressure cannot be adjusted after inflation. In view of the above defects, this application is proposed.
