Air pressure type electric generation shock absorber

The utility model relates to an air pressure type electric generation shock absorber which comprises a shock absorber part, a pipeline part and an electric generation part. When a vehicle is in vibration, a shock absorption rod (2) in the shock absorber part drives a piston (4) to compress air in an upper cavity (A) or a lower cavity (B), the air which is pressed out drives a pneumatic motor (16) in the electric generation part to rotate through the pipeline part, and the pneumatic motor (16) drives an electric generator (17) to generate electricity for other electric elements of the vehicle. The air pressure type electric generation shock absorber absorbs shock of the vehicle, also converts vibration energy of the vehicle to air pressure energy at the same time, the air pressure energy can be further converted to electric energy for the vehicle to use, and the purpose of energy conservation is achieved.
