Title:

NON-CONTACT ELECTRIC POWER SUPPLYING DEVICE FOR MOVING BODY

Document Type and Number:

Japanese Patent JP3765041

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To enable to surely electric supply power to a moving body at every loading point by mounting a coil for receiving power at the moving body side at the end of an end member of a supporting arm.
SOLUTION: A coil 11 for receiving power mounted at end members 9c of a front and a rear supporting arm 9, 9 abuts against a magnetic body 26 of a coil 15 for supplying power of a power supplying circuit 10 and then is plunged in. When the plunge of the coil 11 for receiving power is detected by a plunge detecting sensor 9d, an output switch starts working to allow AC current from a source of AC to flow in the electric power supplying circuit 10. At the same time, the extension of each of the supporting arms 9 stops. Then, the coil 11 for receiving power mounted on the end members 9c of the supporting arms 9, 9 receives from the coil 15 for supplying power induced electromotive force appearing between the coil 11 for receiving power and the coil 15 for supplying power in a non-contact state with the coil 15 for supplying power. The received power is then supplied to an electric circuit mounted on a vehicle through a stabilized power supply. By this method, power can be surely supplied at every loading point.
