Abstract

The application discloses a self-generating device, comprising: a piezoelectric patch, the bottom of which is provided with a deformation space for accommodating the deformed piezoelectric patch; theoscillating mechanism comprises an elastic device and a mass block which are connected with each other; the oscillation triggering mechanism has a threshold triggering function and can be reset; the bottom surface of the mass block is in contact with the oscillation triggering mechanism; the elastic device can drive the oscillation triggering mechanism through the mass block after being stressed,so that the oscillation triggering mechanism abuts against the piezoelectric plate, and when the driving force borne by the oscillation triggering mechanism is larger than a triggering threshold value, the oscillation mechanism generates oscillation, the piezoelectric plate bears alternating loads, and multiple times of deformation are generated in the deformation space. According to the self-generating device provided by the embodiment of the invention, the oscillation mechanism is arranged, and the elastic device of the oscillation mechanism can drive the mass block to generate oscillation after being stressed, so that the piezoelectric plate generates multiple times of deformation in the deformation space, mechanical energy generated by oscillation of the mass block is converted into electric energy, and the generating capacity is greatly increased.

Description

technical field [0001] The present application relates to the technical field of self-generating equipment, in particular to a self-generating device. Background technique [0002] The statements herein merely provide background information related to the present application and may not necessarily constitute prior art. [0003] At present, there are various piezoelectric power generation devices on the market, which are favored due to their simple structure and few components. However, most of the piezoelectric power generation devices have low power generation efficiency, and the power converted from mechanical energy is small, which is difficult to meet the application requirements of self-power generation. Contents of the invention [0004] The purpose of the embodiments of the present application is to provide a self-generating device, aiming at solving the problems that the piezoelectric generating device has low power generation efficiency and small power generatio...
