Piezoelectric type automobile body bumper shock absorber energy collection system

The utility model discloses a piezoelectric type automobile body bumper shock absorber energy collection system mainly includes pressure transmission system, conversion of energy system, electric energy collecting system. Go between pressure transmission system and the conversion of energy system close joining in marriage, pressure transmission system rotates the rotation action that turns into linear action on the axle by the gear interlock, slides between the turning block of rethread cam and conversion of energy system and meets, and the linear position of going of single of shaking the bumper shock absorber turns into a lot of linearity action that the cam assaults piezoceramics, and the deformation of piezoceramics high frequency constantly produces the electric energy and imports the electric energy collecting system. The energy process of collecting of the invention design has fully used the tooth cooperation to assault single action changing into a lot of, has greatly improved the utilization ratio of automobile body vibrations energy, simultaneously, adopts multiply piezoceramics to carry out conversion of energy, maximum application piezoceramics's electromechanical conversion characteristic to energy transformation ratio has been improved.
