The invention discloses a pavement energy harvesting device based on a paper folding rebound mechanism. The device comprises a working cylinder, a piston rod, the paper folding rebound mechanism, a dielectric pair and an electric energy transmission circuit, wherein the dielectric pair and the electric energy transmission circuit are fixed on the surface of the paper folding rebound mechanism. Thedielectric pair comprises two dielectric material layers with opposite polarities and two metal electrode layers; when a vehicle is pressed on the upper portion, the piston rod generates downward displacement, after the vehicle leaves, displacement is recovered, and in the process, the paper folding rebound mechanism makes contact with and is separated from the dielectric pair through compression-rebound movement, charge transfer is generated, mechanical energy is converted into electric energy, and the electric energy is transmitted through the electric energy transmission circuit. The paperfolding rebound mechanism provides a larger effective surface area, and is high in space utilization rate and energy conversion efficiency.
Description
technical field [0001] The invention relates to the field of energy harvesting, in particular to a road surface energy harvesting device based on an origami rebound mechanism. Background technique [0002] The energy harvesting device solves the problem that some micro sensors need battery power, which greatly improves the portability, endurance and working stability of the device; however, the traditional energy harvesting device has the disadvantage of a small specific surface area. In daily life, the energy generated by road traffic is huge, but people have been unable to effectively utilize the energy generated in this process, resulting in considerable energy loss. Especially when the car is running on the road, the road vibration caused by it contains a lot of vibration energy. Adopting a suitable energy harvesting device to realize the transformation from vibration energy to electric energy during the vibration process of the road surface will save a lot of energy fo...
