Problems solved by technology

When there is no mass block at the free end of the cantilever beam, the cantilever beam can only be subjected to intermittent vibrations due to external influences, so the generated electric energy will inevitably be unable to accumulate continuously, resulting in a large loss of output electric energy from the piezoelectric sheet

Abstract

The invention discloses a pedal type continuous vibration piezoelectric generating device. The device mainly comprises a pedal which is mounted at the position of an opening in the center of an upper cover of a box body through a spring mechanism, and the pedal drives N groups of ratchet mechanisms to link a vibration piezoelectric generator through a gear mechanism, wherein N is a natural numberexcept zero. After the pedal is stepped, acting energy is transferred to a flywheel through the gear mechanism and the ratchet mechanisms, and a pick tray is driven by the flywheel which continuouslyrotates in one direction to move a metal sheet of a cantilever beam and ensure the continuous vibration of the cantilever beam. The invention can bear repeated stepping, converts the intermittent stepping power of a stream of people into the continuous vibration of the cantilever beam, and the energized piezoelectric sheet can accordingly generate continuous electric power output so as to finallyreach the aim of effectively accumulating the electric power.
