Abstract

The invention relates to a pull-and-pressing type full-stroke energy harvesting friction-piezoelectric-electromagnetic composite generator. The composite generator is characterized by realizing continuous operation and output under one-time excitation, and can efficiently collect random irregular mechanical movement energy in the nature. The pull-and-pressing type full-stroke energy harvesting friction-piezoelectric-electromagnetic composite generator comprises an upper shell, a lower shell, a base assembly, a flywheel assembly, a bolt, an upper cover plate assembly and a pressing plate assembly; and the flywheel assembly has a certain energy storage function and can rotate for a long time. As a flywheel rotates, a friction material performs continuous sweeping type friction on an electrode, so that electric energy is generated based on a contact electrification principle and an electrostatic induction principle; and mechanical movement energy harvesting efficiency can be improved through electromagnetic power generation and piezoelectric power generation. Therefore, with the pull-and-pressing type full-stroke energy harvesting friction-piezoelectric-electromagnetic composite generator adopted, random irregular mechanical movement energy can be converted into electric energy efficiently.

Description

technical field [0001] The invention relates to a friction-piezoelectric-electromagnetic composite generator of tension-compression type full-stroke energy harvesting, which belongs to the field of energy collection. Background technique [0002] The gradual reduction of traditional energy sources and the exploration of renewable energy sources have become the main concerns of people. There is a large amount of mechanical energy that can be collected in the environment, and the reasonable collection of mechanical energy has become a major problem in the efficient use of energy. [0003] Triboelectric nanogenerators, with their potential to recycle mechanical energy from their surroundings, are being investigated by researchers all over the world. At the same time, piezoelectric power generation technology and electromagnetic power generation technology are also widely used in the collection of environmental vibration energy and impact energy. However, most of the mechanica...
