Pressing piezoelectric power generation device

Abstract

The invention relates to the technical field of power generation, in particular to a pressing piezoelectric power generation device. The piezoelectric power generation device of the invention is a triggered piezoelectric power generation device based on pressure change, and operates in the way of a key. In order to make piezoelectric oscillators deform largely to form higher power generating capacity, the piezoelectric oscillators are supported in a mode of simple peripheral support. In view of the characteristics of high voltage and low current of piezoelectric power generation, a plurality of circular piezoelectric films are connected in parallel to obtain an appropriate current and voltage so as to improve the generation power. During use, when the key is pressed with a finger, the piezoelectric oscillators bend and generate electricity to supply power to external electromechanical equipment. The operation is similar to pressing a remote control function button to issue an instruction. The pressing piezoelectric power generation device of the invention is simple to operate and small. As long as the key is pressed slightly, each piezoelectric oscillator can be deformed. The greatest advantage is that the device can be completely sealed, is less prone to wrong operation and is of higher reliability.

Description

technical field [0001] The invention relates to the technical field of power generation, in particular to a press-type piezoelectric power generation device. Background technique [0002] At present, for some moving parts, mechanical energy will also be generated during the working process, for example, vehicle tires will be deformed during the rotation process, which will generate mechanical energy. Whether the mechanical energy produced by shoes or tires will be lost in the air in vain. That is to say, the existing moving parts such as shoes and tires fail to collect and utilize the mechanical energy generated by them, resulting in a waste of energy [0003] With the development of electronic technology, piezoelectric ceramics can convert these mechanical energies into electrical energy. Piezoelectric wafers formed by the positive piezoelectric effect or inverse piezoelectric effect of piezoelectric technology have been widely used in many fields, such as piezoelectric mo...
