Telescopic piezoelectric vibration generator

Abstract

The invention relates to a telescopic piezoelectric vibration generator, and belongs to the technical field of power generation. A bottom plate and a top plate are welded with stand columns. The bottom plate is provided with bottom side lugs with pin holes, and the top plate is provided with top side lugs with pin holes. The upper side and the lower side of a mass block are each provided with two middle side lugs with pin holes. Each piezoelectric vibrator is composed of a metal sheet and a piezoelectric plate adhesively connected to an arc protrusion of the metal sheet. An energy converter is composed of each piezoelectric vibrator and cotter pin sleeves riveted into the two ends of the piezoelectric vibrator. A pin shaft riveted to the pin hole of one top side lug is sleeved with the pin sleeve at one end of the energy converter I, and a pin shaft riveted into the pin hole of one middle side lug on the upper side of the mass block is sleeved with the pin sleeve at the other end of the energy converter I. A pin shaft riveted into the pin hole of one bottom side lug is sleeved with the pin sleeve at one end of the energy converter II, and a pin shaft riveted into the pin hole of one middle side lug on the lower side of the mass block is sleeved with the pin sleeve at the other end of the energy converter II. The telescopic piezoelectric vibration generator has the advantages that the two telescopic piezoelectric vibrators are connected with the frame and the mass block through the pin shafts, deformation is restricted, reliability is high, the low-frequency characteristics are good, the power generation capacity is high, and the vibration direction adaptability capacity is high.

Description
