Vibration frequency power generation device

The invention relates to a vibration frequency power generation device. The vibration frequency power generation device comprises a gear I, a gear II, a gear III, a gear IV, a gear V, a shaft I, a shaft II, a shaft III and a double-face rack. When the double-face rack moves upwards, the gear I idles anticlockwise, the gear III rotates clockwise and drags the shaft II to rotate, the gear IV rotatesalong with the shaft II, transmission is conducted to the gear II through the gear V, and the gear II rotates clockwise and drags the shaft I to rotate. When the double-face rack downwards moves, thegear III idles anticlockwise, the gear I rotates clockwise and drags the shaft I to rotate. Up-down movement of the double-face rack is driven through vibration of a suspension spring, it is guaranteed that the shaft I constantly rotates in the same direction through transmission of a plurality of racks, and a power generator is driven to generate power through rotation of the shaft I.
