Title:
MICRO POWER GENERATION DEVICE, AND BICYCLE LAMP AND DOOR AND WINDOW ALARM USING THE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/145373
Kind Code:
A1
Abstract:
A micro power generation device, and a bicycle lamp and a door and window alarm using the device. The micro power generation device comprises: a rotary magnet (1), being able to rotate freely according to changes of an external magnetic field, and coils (2) wound around the rotary magnet (1). The micro power generation device further comprises: a positioning magnet (3) and a disturbance magnetic block (5); the positioning magnet (3) is fixedly provided on one side of the rotary magnet (1); the disturbance magnetic block (5) is movably provided on one side of the rotary magnet (1); when the disturbance magnetic block (5) moves close to the rotary magnet (1), the disturbance magnetic block (5) attracts the rotary magnet (1) to enable the rotary magnet to turn to the side of the disturbance magnetic block (5); and when the disturbance magnetic block (5) moves away from the rotary magnet (1), the positioning magnet (3) attracts the rotary magnet (1) to enable the rotary magnet to turn to the side of the positioning magnet (3). The micro power generation device is simple in structure. As the rotary magnet (1), positioning magnet (3), and disturbance magnetic block (5) are provided, when the disturbance magnetic block (5) enters and leaves the disturbance region, the rotary magnet (1) can be enabled to rotate, thereby generating induction electric energy, providing high power generation efficiency.
