Document Type and Number:
WIPO Patent Application WO/2018/181341
Kind Code:
A1
Abstract:
[Problem] To provide a power generation mechanism and a power generation method, wherein a certain amount of power generation can be achieved and a reliable switching operation can be performed no matter how slow the force driving the power generation mechanism is. [Solution] This power generation mechanism is formed of at least a first movable component, a second movable component, a torsional coil spring, a power generator, and a housing, wherein: the first movable component and the second movable component are gears; a first wound section and a second wound section of the torsional coil spring are wound around a first center shaft in opposite directions to each other; initial elastic energy ie1 is imparted to the first wound section and initial energy ie2 is imparted to the second wound section, the absolute values of ie1 and ie2 being set to be equal to each other; the second movable component is rotated by a force coming from outside the power generation mechanism, and the first movable component is rotated by engaging the gears of the first movable component and the second movable component; elastic energy ie12 is accumulated in the first wound section; and power generation is performed by disengaging the gears of the first movable component and the second movable component and rotating the first center shaft in the reverse direction by means of ie12, and the first center shaft is rotated by means of ie1 and ie2.
