Low-frequency pre-tightening type bistable vibration energy collector and manufacturing method thereof

The invention discloses a low-frequency pre-tightening type bistable vibration energy collector and a manufacturing method thereof. The low-frequency pre-tightening type bistable vibration energy collector comprises an energy recovery device, a vertical rod with one fixed end and a cantilever beam with certain bending deflection, one end of the cantilever beam is fixedly connected with the energy recovery device, and the other end of the cantilever beam is fixedly connected with the free end of the vertical rod; and a resin plate is arranged at the joint of the cantilever beam and the energy recovery device, and a screw sequentially penetrates through the cantilever beam, the resin plate and the boss end of the energy recovery device to be fixed. According to the vibration energy collector, the inherent elastic potential energy generated by the deformation of the cantilever beam is used as a pressure source of the double potential wells, and the working efficiency in a low-frequency vibration environment is i
