Stepped piezoelectric generator

Abstract

The invention discloses a stepped piezoelectric generator which comprises a first end cover, a second end cover, a cylinder body, a shaft, a shaft base, a stepped fixed piezoelectric ceramic double-wafer base, a rotary step cam, piezoelectric ceramic double-wafers and leads. The first end cover and the second end cover are arranged at the corresponding two ends of the cylinder body respectively so that a generator body can be formed; the shaft base is arranged at the bottom inside the generator body, one end of the shaft is connected with the shaft base through one bearing and the other end of the shaft penetrates through the second end cover through the other bearing; the rotary step cam is arranged on the shaft, the stepped fixed piezoelectric ceramic double-wafer base is arranged in the generator body, and the piezoelectric ceramic double-wafers are arranged between the stepped fixed piezoelectric ceramic double-wafer base and the rotary step cam; one lead is arranged at one end of each piezoelectric ceramic double-wafer. The stepped piezoelectric generator can effectively improve the generating efficiency of a piezoelectric crystal and prolong the service life of the piezoelectric crystal and is good in practicability.
