Title:
POWER GENERATION MECHANISM AND POWER GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/013141
Kind Code:
A1
Abstract:
[Problem] To provide a power generation mechanism and a power generation method with which it is possible to generate a fixed power amount with high efficiency and execute a reliable switching operation, no matter how slow the speed of the force operating the power generation mechanism. [Solution] This power generation mechanism is formed from a first movable component, a second movable component, a torsion coil spring, a power generator, and a housing. A first wound section and a second wound section of the torsion coil spring are wound around a first center shaft in opposite directions to each other, initial elastic energy ie1 is applied to the first wound section and initial elastic energy ie2 is applied to the second wound section, the absolute values of the ie2 and the ie1 are set to be equal to each other, and the first center shaft and a shaft of the power generator are coupled by two spur gears or bevel gears. By the second movable component being rotated and the first movable component being rotated, elastic energy ie12 is accumulated in the first wound section, and by the teeth of the first and second movable components being disengaged, the first center shaft is made to rotate in the opposite direction by ie12, causing the power generator to generate power. The gear ratio between the two spur gears or bevel gears is such that it is possible to generate a power amount that is from 50% to 100% of the peak power amount from the shaft of the power generator.
