COMPACT GENERATOR FOR ROAD

摘要

PURPOSE: A small power generation device for roads is provided to produce enough electricity even in when an upper case ascends and descends. CONSTITUTION: A small power generation device(100) for roads comprises a housing(10), a return spring(20), a power transmission unit(30), and a clutch unit(40). The housing comprises an upper case(11), and a lower case(12). The upper case ascends and descends according to loads. The return spring is fixed to the bottom of the upper case. If the loads are removed, the return spring pushes up the upper case. The power transmission unit transmits torque to a motor shaft(2) by converting the ascending and descending motions of the upper case into a rotary motion. The clutch unit is coupled to the power transmission unit, and transmits only unidirectional torque to the motor shaft.
