Abstract
A mechanical energy harvesting system includes a base seat unit, a rotating shaft device, and a driving device. The base seat unit includes first and second seat bodies. The rotating shaft device is rotatably mounted to the first seat body. The driving device is disposed on the base seat unit and includes at least one driving unit sleeved on the rotating shaft device for driving the rotating shaft device to rotate and thus generate rotational kinetic energy, and at least one transmission unit connected between the second seat body and the driving unit and configured to drive the rotating shaft device to rotate when the second seat body swings relative to the first seat body, so as to generate the rotational kinetic energy.
