Title:
COIL DEVICE FOR POWER TRANSMISSION, NON-CONTACT POWER TRANSMISSION SYSTEM AND MANUFACTURING METHOD OF COIL DEVICE FOR POWER TRANSMISSION
Document Type and Number:
Japanese Patent JP2019062135
Kind Code:
A
Abstract:
To provide a coil device for power transmission and a non-contact power transmission system capable of obtaining high power transmission efficiency similarly to a case provided with a thick core, without thickening a magnetic substance.SOLUTION: A coil device for power transmission includes a coil, a sheet of magnetic substance covering one winding axis direction of the coil, and a core of magnetic substance placed on the inside of the coil. The core has a shaft elongating in the winding axis direction, and one or more than one flanges provided at least in the way of the winding axis direction of the shaft. A non-contact power transmission system has the coil device for power transmission as a power transmission coil and a power reception coil, and when a power transmission device and a power reception device are made to face each other, the cores of the power transmission coil and the power reception coil come into contact, or are brought into contact via a magnetic substance provided in the member interposed between the power transmission coil and the power reception coil.SELECTED DRAWING: Figure 1
