Abstract
The present invention relates to a vibration energy harvest device. In the present invention, the vibration energy harvest device is provided for being used to recycle the mechanical energy and thermal energy generated during the vibration, and effectively to improve the power generation efficiency with newly added hydraulic motor and electricity generating unit. Wherein by using an ameliorating valve module and removing the damping hole in the prior art, no matter the damping oil flows from inner cylinder module through hydraulic motor to outer cylinder module or the contrary direction, the flowing damping oil could avoid the hydraulic motor from reciprocating to improve the power generation efficiency.
