A piezoelectric generating floor

Abstract

The invention relates to a piezoelectric power generating floor, which comprises an upper-layer lifting part and a lower-layer power generating part, wherein the upper-layer lifting part comprises anupper-layer cover plate, a lifting spring, a hemispherical pressure rod and a middle-layer positioning plate, and the lower-layer power generating part comprises moving sliding blocks, fixed piezoelectric cantilever beams, moving piezoelectric cantilever beams, a lower-layer substrate, pressure springs and piezoelectric pieces. Pressure is applied to the moving sliding blocks by the hemisphericalpressure rog, and electric energy is generated by movement of the moving piezoelectric cantilever beams mounted on the moving sliding blocks and impact of the tail ends of the fixed piezoelectric cantilever beams fixed on the lower-layer substrate. In addition, each pressure spring at one end of the corresponding moving sliding block is squeezed to apply pressure to the piezoelectric pieces to generate electric energy. When the pressure is released, the upper-layer cover plate of the floor ascends when the pressure, the moving sliding blocks move towards opposite directions under the action ofrestoring forces of the pressure springs at the end parts and the tail ends of the piezoelectric cantilever beams impact again to generate electric energy. The piezoelectric power generating floor isapplied to energy supply of smart home or electric energy collection of public places with relatively high human traffic.
