The present invention relates to a vibrating piezoelectric generating device and piezoelectric method thereof, comprising a supporting shell, a spring steel sheet on which a piezoelectric sheet is placed, and a transmission structure. Both sides of the spring steel sheet are connected to the transmission structure and the transmission structure uses A spring steel sheet is bent around the center to create a voltage. The invention combines the two sides of the spring steel sheet with the transmission mechanism, and the transmission mechanism makes the spring steel sheet or piezoelectric sheet bend around the middle. Compared with the traditional cantilever beam structure, the degree of bending deformation of the spring steel sheet or piezoelectric sheet is increased. This makes the vibrating piezoelectric energy generating device have wider application prospects. The device has the advantages of simple structure, stable operation, novel energy collection principle, high energy collection efficiency and the like.
Description
technical field [0001] The invention relates to the technical field of energy collection, in particular to a vibrating piezoelectric generating device and a piezoelectric method thereof. Background technique [0002] With the continuous progress and development of science and technology, smart devices that tend to be miniaturized and microelectronic can be seen everywhere around us. While being widely used, it also promotes the emergence and development of low-power energy supply technology of MEMS. Traditional chemical batteries that provide power for this type of equipment have many disadvantages, such as regular replacement of used batteries and high maintenance costs. Mechanical vibration energy can be seen everywhere in our life, and has the advantages of wide sources, clean and environmental protection. In recent years, the technology of using piezoelectric materials to obtain vibration energy from the environment, convert it into electrical energy and store it, and p...
