Abstract
The invention discloses a recovery method of automobile vibration energy. The method is characterized in that a piezoelectric device is arranged in a pavement; when an automobile passes by, the piezoelectric device converts the generated mechanical energy into the electric energy; and then the electric energy is converted into the collectable one by a conversion circuit and the collectable electric energy is storage into an energy collection device. On the basis of the structure, the vibration energy that is generated during the automobile driving process can be recycled in a centralized mode and is converted into the electric energy for recycle. Meanwhile, after the vibration energy that is generated during the automobile driving process is collected, the damages on the pavement can be reduced, thereby prolonging the service life of the pavement.
Description
Technical field
The present invention relates to the recycling field of energy source of car, particularly a kind of recovery method of automobile vibrational energy.
Background technology
Along with people's paying close attention to day by day significantly energy problem, energy-conservation and energy recycling is an important development direction of automobile industry.Present stage reclaims mostly to concentrate on to automobile vibrational energy and retracting device is placed in automobile suspension system, to collect the electric system of automobile vibrational energy for automobile itself.But conventional method have ignored the vibrational energy that automobile itself produces as a system, the vibrational energy of this part has greatly improved relative to suspension vibrational energy.
For the problems referred to above, a kind of novel recovery method is provided, the vibrational energy of automobile is recycled.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of recovery method of automobile vibrational energy, is recycled the vibrational energy of automobile.
