Automatic electricity generation energy storage device

Abstract

The invention discloses an automatic electricity generation energy storage device, and belongs to the field of electricity generation devices. The automatic electricity generation energy storage device comprises a shell. A rotating shaft is arranged inside the shell. A cam is installed on the rotating shaft. At least one set of electricity generation unit is arranged at the portion, on the periphery of the cam, of the shell. Each electricity generation unit comprises a frame, wherein a plurality of elastic cantilever slabs are arranged inside the frame in parallel, the center of each elastic cantilever slab is connected with a mass block, piezoelectric patches are stuck to the surface of the elastic cantilever slabs, and the piezoelectric patches are electrically connected with an electric energy storage device body; one end of each mass block is elastically supported into the corresponding frame, the other end of each mass block is correspondingly provided with an ejector rod, the ejector rods are arranged inside guiding pieces in a matched mode, and the guiding pieces are fixedly connected with the shell; according to the positions of the ejector rods, the ejector rods make contact with and press the mass blocks in a clearance mode when the cam rotates. When the cam rotates, the mass blocks can elastically vibrate, the piezoelectric patches generate the automatic electricity generation effect, the vibration mechanical energy is converted into electric energy to be stored, and the automatic electricity generation energy storage device can be used as a power source of a small-power electricity consumption device.

Description

technical field [0001] The invention relates to a power generating device, in particular to a small power generating device. Background technique [0002] At present, traditional energy research and development can be mainly divided into five aspects: generation and conversion of large-scale energy; development of sustainable green energy; efficient transmission of electric power and smart grid; high-density storage of electric energy; effective energy-saving technology and energy recovery . Most of our demand for electric energy is concentrated in industrial electricity, transportation, construction, home and office energy. These energy needs can be met by a large-scale electrical grid. However, since the popularization of personal mobile electronic products such as laptops and mobile phones, it is particularly important to solve small-scale power consumption, which mainly relies on batteries at present. In the near future, due to the development of micro-nano systems an...
