Multipurpose piezoelectric vibration generator

Abstract

The invention relates to a multipurpose piezoelectric vibration generator, and belongs to the technical field of new energy. The bottom wall of a shell is provided with a guide pin, the end part of the side wall is provided with an end cover, and an airbag is tied to the end cover through a rope; two ends of a cross beam of a bracket are provided with longitudinal beams with inclined mounting surfaces; the upper and lower ends of an exciter are provided with communicated upper and lower guide holes, and the left and right sides are provided with cams; a stepped shaft is sequentially provided with a thin shaft, a middle shaft and a thick shaft from top to bottom, the end part of the thick shaft is provided with a guide hole, and the guide hole sleeves the guide pin and crimps a support spring on the guide pin; the upper guide hole and the lower guide hole of the exciter respectively sleeve the middle shaft and the thick shaft of the stepped shaft, and the thick shaft crimps a lower spring on the top wall of the lower guide hole; the cross beam of the bracket and an upper frequency modulation block are installed on the thin shaft of the stepped shaft, the upper frequency modulation block crimps a buffer spring on the end cover, and the exciter crimps the upper spring sleeving the middle shaft on the cross beam; and a cantilever beam type piezoelectric vibrator formed by bonding asubstrate and a piezoelectric patch which are equal in thickness is mounted on the mounting surface of the bracket, and the flanging of the substrate is crimped to the midpoint of the inclined surface of the cam when the piezoelectric vibrator does not work.

Description

Technical field [0001] The invention belongs to the technical field of new energy, and specifically relates to a multi-purpose piezoelectric vibration generator, which is used for the recovery of multi-directional vibration, directional flow, ocean wave energy and the like. Background technique [0002] In recent years, with the maturity of wireless sensor network technology and its popularization in environmental monitoring, health monitoring of buildings and bridges, industry, military, and public security, micro-piezoelectric devices that provide continuous energy supply The research on generators has received extensive attention from scholars at home and abroad. The miniature piezoelectric generators that have been proposed can be successfully used for effective recovery of vibration energy, wind energy, water flow energy, and ocean wave energy. However, the existing piezoelectric generators have a single function, that is, they can usually only be used to recover one kind o...

Problems solved by technology

However, these existing piezoelectric generators have a single function, that is, they can usually only be used to recover energy from one environment, and their reliability and environmental adaptability are very limited, which is not conducive to the popularization and application of piezoelectric power generation technology.
