Title:
VIBRATION POWERED GENERATOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/208602
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable the thickness of a vibration powered generator device to be reduced even when a structure in which a movable-side unit is housed inside a case is adopted. The vibration powered generator device is structured such that a movable-side unit comprising a conductive coil vertically vibrates with respect to a stationary-side unit 40 comprising magnets 42 and yokes 44, and the vibration powered generator device is provided with a case 50, serving as the stationary-side unit 40, for housing the movable-side unit. Furthermore, the device has a structure in which concave parts 50Ac, 50Bc are respectively formed on one pair of front and back wall surface parts 50Aa, 50Ba of the case 50, and vertically arranged one pair of upper and lower openings 50Ad, 50Bd are respectively formed in the concave parts 50Ac, 50Bc. In addition, the device is structured such that the yokes 44 are supported on the concave parts 50Ac, 50Bc, and the magnets 42 are housed in the respective openings 50Ad, 50Bd in a state of being magnetically attracted to the yokes 44. Consequently, the magnets 42 and the yokes 44 are allowed to be arranged by utilizing portions of the respective wall surface parts 50Aa, 50Ba.
