Contactless Power Supply Mechanism and Secondary Coil for Contactless Power Supply Mechanism |
摘要 |
In a contactless power supply mechanism, a power receiving unit for supplying power to an electric device includes a secondary coil and a power supplying unit for supplying power to the power receiving unit includes a primary coil. The primary coil includes a primary core formed of magnetic material and a length of winding wire wounded around the primary core. The secondary coil includes a bar-shaped secondary core formed of magnetic material, a length of winding wire wounded around the secondary core and a magnetic sheet attached to at least one of end faces of the secondary core. The magnetic sheet includes a close-contact portion placed in close-contact with the end face of the secondary core and a curved portion which extends outwards from the close-contact portion beyond an outer edge of the end face and whose normal line has a portion un-parallel with an axial direction of the secondary core. |

1. A contactless power supply mechanism comprising:
a power receiving unit having a secondary coil and configured to supply power to an electric device; and a power supplying unit having a primary coil and configured to supply power to the power receiving unit; wherein the primary coil includes a primary core formed of magnetic material and a length of winding wire formed of conductive material and wound around the primary core; the secondary coil includes a bar-shaped secondary core formed of magnetic material, a length of winding wire formed of conductive material and wound around the secondary core and a magnetic sheet attached to at least one of end faces of the secondary core; and the magnetic sheet includes a close-contact portion placed in close-contact with the end face of the secondary core and a curved portion which extends outwards from the close-contact portion beyond an outer edge of the end face and whose normal line has a portion un-parallel with an axial direction of the secondary core. |
