Electromagnetic composite vibration energy collector

摘要

Problem to be solved: to provide an electromagnetic composite vibration energy collector capable of further expanding the application environment and obtaining more energy.Solution: an electromagnetic hybrid vibration energy collector comprising a base layer 2, a permanent magnet component, a piezoelectric layer 3, and a support frame 4 disposed on the base vibrating table 1.The base layer is an arcuate arch structure detachably mounted on two opposite rear walls of the support frame through torsion springs 5 at both ends.Since the base layer is detachably attached to the support frame through the torsion spring, it is possible to realize a restricted state of the arch only by replacing the torsion spring having different rigidity, thereby achieving adjustment of the natural frequency of the arch structure.Moreover, the collector simultaneously collects the current produced from the piezoelectric effect and the electromagnetic effect.Diagram
