The present invention relates to a piezoelectric generator and, more specifically, to a piezoelectric generator using a lever comprising a supporting plate which includes; a first supporting plate of a board shape which forms a penetration groove on the center to minimize energy loss by applying the principle of the lever when wind force and hydraulic energy are transferred to a piezoelectric element; and a second supporting plate of a board shape which is combined to the lower side of the first supporting plate and forms a penetration hole on the center. The piezoelectric generator comprises a rotary unit including a pressurizing rod in which a cross section shape of the front side is a triangular shape which forms right and left asymmetry with a vertical shaft as the center. The side of the pressurizing rod is formed long in a transverse direction and forms a rod shape. The rotary unit rotates in a transverse direction with the first supporting plate and transfers power to a lever unit in a longitudinal direction. The piezoelectric generator comprises multiple lever units which are formed on the top of the first supporting plate and are able to strike multiple piezoelectric element units. Both ends of the lever unit are moved to in a longitudinal direction. The piezoelectric generator comprises the multiple piezoelectric element units which are fixated and installed on the top of the second supporting plate. Therefore, the multiple lever units and the multiple piezoelectric element units are installed in many areas with a rotary shaft as the center by changing a rotary motion which rotates in a transverse direction to a pressurizing motion which moves in a longitudinal direction. Also, energy loss generated in a process in which energy by wind power or water power is transferred to a piezoelectric element is minimized. The resistance which is added to the rotary unit is minimized by minimizing repulsive power of the lever unit. |
