振動発電機
Document Type and Number:
Japanese Patent JP5344386
Kind Code:
B2
Abstract:
A vibration electric power generator includes an iron core (10) having a coil (11) wound therearound, a magnet member (20) relatively moved with respect to the iron core (10) by vibrations caused during running of a bicycle; and a nonmagnetic member (30A, 30B) fixed to the iron core (10) and being in close contact with the magnet member (20). A plurality of magnets (21-28) are stacked such that identical poles face each other. Switching is realized, by the vibrations caused during the running of the bicycle, between a state in which a first protrusion (13A) of the iron core (10) is attracted and brought into contact with a north pole magnetism collecting and permeative plate (23A, 25A, 27A) and a second protrusion (13B) of the iron core (10) is attracted and brought into contact with a south pole magnetism collecting and permeative plate (22A, 24A, 26A, 28A) and a state in which the second protrusion (13B) is attracted and brought into contact with a north pole magnetism collecting and permeative plate (23A, 25A, 27A) and the first protrusion (13A) is attracted and brought into contact with a south pole magnetism collecting and permeative plate (22A, 24A, 26A, 28A).
