WIRELESS POWER TRANSFER SYSTEM AND VEHICLE POWER SUPPLY DEVICE
First Claim
1. A wireless power transfer system comprising:
- a power receiving apparatus having a power supply secondary coil that is a coil circuit capable of performing wireless power transfer, the power receiving apparatus being capable of supplying electric power to a load;
a power supply apparatus having a power supply primary coil that is a coil circuit capable of performing the wireless power transfer, and a drive circuit that drives the power supply primary coil;
a primary coil support member provided with a fitting member that is fit with a fit member, the primary coil support member being configured to support the power supply primary coil;
a moving body provided with the fit member with which the fitting member is fit, the moving body being capable of supporting the power supply secondary coil at a predetermined position in a predetermined posture; and
a posture/position adjustment mechanism capable of adjusting a relative posture or position between the primary coil support member and the moving body to change the posture between a releasing posture and a fitting posture, the releasing posture being such a posture that the fitting member releases the fit member, the fitting posture being such a posture that the fitting member is fit with the fit member, whereinwhen the moving body supports the power supply secondary coil at the predetermined position in the predetermined posture and is located between the power supply primary coil and the power supply secondary coil, the posture/position adjustment mechanism adjusts the relative posture or position between the primary coil support member and the moving body such that the releasing posture is changed to the fitting posture, and the power supply apparatus performs the wireless power transfer from the power supply primary coil to the power supply secondary coil in the fitting posture.

Abstract
A wireless power transfer system includes: a primary coil support member provided with a fitting member that is fit with a fit member, the primary coil support member being configured to support the power supply primary coil; a secondary coil support member provided with the fit member with which the fitting member is fit, the secondary coil support member being configured to support the power supply secondary coil; and a posture/position adjustment mechanism capable of adjusting a relative posture or position between the primary coil support member and the secondary coil support member to change the posture between a releasing posture and a fitting posture. When the relative posture is changed from the releasing posture to the fitting posture by the adjustment of the posture/position adjustment mechanism, the power supply apparatus performs wireless power transfer from the power supply primary coil to the power supply secondary coil.
