| 摘要 |
The present invention can be changeable to a mechanical motion capable of putting up a step one by one by sequentially accumulating energy generated by gravity in a spring or a piezoelectric element having spiral elastic force with elastic force or elasticity. The composition of the present invention to achieve the purpose is rotated by a supporting axis (1-4) supported on a down step plate (1-1) and is transferred to a power transfer axis (1-3). Gravity energy is transferred to a wound spring (1-6) as elastic energy. The present invention is formed of a generator to generate a part of a power motor which ascends by receiving the elastic force or electric force of the spring (1-6) or a piezoelectric electric element (1-6). Additionally, induction of a high efficiency piezoelectric element is possible and the energy efficiency of the step can be improved when an energy harvesting system using the piezoelectric element which is made of an elastic body according to the present invention is combined. |
