Piezoelectric power generation air spring

The invention discloses a piezoelectric power generation air spring which comprises an air spring, and a buffer block and a piezoelectric material arranged in the air spring, and is characterized in that the piezoelectric material and the buffer block are fixed on the inner surface of at least one of cover plates at the upper end and the lower end of the air spring, and the piezoelectric material is connected with a power storage device by a lead. As the air pressure on the piezoelectric material is distributed uniformly all the time, the pressure of air in the air spring in vibration can be converted into electricity for use by fully utilizing the piezoelectric effect of the piezoelectric material, thereby achieving the aim of energy conservation and emission reduction. In the air spring, the external structure and the installation form are not changed, the structure is simple, the design is reasonable, and the use is reliable.
