PIEZOELECTRIC GENERATOR UNIT FOR USING A PIEZOELECTRIC BIMORPH

摘要

PURPOSE: A unit for a piezoelectric generator using a piezoelectric bimorph is provided to efficiently generate electric energy by converting a linear movement into a rotational movement by using the load pressure due to the vibration and the pressure due to the moving gravity of a vehicle. CONSTITUTION: A housing(100) has a cylindrical shape to supply fluid to a flywheel(200). A fluid spray path(110) and a fluid discharge path(120) are formed on the outer side of the housing. A plurality of protrusions(210) are formed in the fly wheel with a constant space along a circumferential direction. A piezoelectric member(300) is radially installed in the fly wheel. A central axis(400) is installed by the piezoelectric member and a connection member(410).
