Self-resetting power generation device

Abstract

The invention is applicable to the technical field of electrical and electronic switches, and provides a self-resetting power generation device, which comprises a base, a key board, a gland, a metal pressing board with a pressing part, a self-generating module with a metal pick, and a PCB, and a rotary supporting seat is arranged in the base; a first pressing column and a second pressing column are arranged in the key board; and the metal pressing plate rotates with the rotary supporting seat as a fulcrum under the action of the first pressing column, and then the metal poking piece is pressedthrough the pressing part. A magnet is arranged on one side of the metal pressing plate and is used for returning the metal pressing plate which is separated from the keyboard plate to the original position. According to the self-resetting power generation device, the existing mode that a spring is adopted to reset the metal poking piece is changed, the attraction force of the magnet to the metalpoking piece cannot be changed along with the change of the pressing force, the power generation voltage of the self-generating module is always kept stable, the service life of the magnet is longerthan that of the spring, and the service life of the self-resetting power generation device is prolonged accordingly.

Description

technical field [0001] The invention belongs to the technical field of electrical and electronic switches, and in particular relates to a self-resetting power generation device. Background technique [0002] With the rapid development of modern homes, in order to save the tedious steps of switch wiring, passive switch controllers have gradually appeared on the market. This is usually achieved through built-in batteries or self-generating modules. Among them, the self-generating module has the advantages of environmental protection and long service life, and has more market prospects. At present, the wireless kinetic energy switch on the market uses the pressing self-generating module to provide the power required by the signal processing device, and then controls the corresponding equipment through wireless signal transmission. [0003] In the prior art, the power generation device of the self-generating switch usually adopts energy storage components such as springs to re...

Problems solved by technology

But this has the following problems: when the spring is under pressure, it will generate a corresponding elastic force to hinder its movement. The greater the pressure, the greater the elastic force

Under the elastic buffer, the metal shrapnel of the self-generating module will reduce its own instantaneous speed, thereby reducing the power generation voltage; and the spring will have fatigue life after obvious stress and long-term use, which will affect the subsequent power generation and normal use.
