Abstract

This vehicle includes a vehicle-mounted component mounted below a rear floor panel and an electric power reception device mounted below the rear floor panel and including an electric power reception portion receiving electric power in a non-contact manner from an electric power transmission device including an externally provided electric power transmission portion, and the vehicle-mounted component is arranged flush with and around the electric power reception device.

Claims

1. A vehicle, comprising:

a vehicle-mounted component mounted below a floor panel of the vehicle; and

an electric power reception device mounted below said floor panel and including an electric power reception portion receiving electric power in a non-contact manner from an electric power transmission device including an externally provided electric power transmission portion,

said vehicle-mounted component being arranged flush with and around said electric power reception device.

2. The vehicle according to claim 1, wherein

said vehicle-mounted component has a region facing said electric power reception device subjected to a shielding process.

3. The vehicle according to claim 1, wherein

said floor panel has a region facing said electric power reception device subjected to a shielding process.

4. The vehicle according to claim 1, wherein

said electric power reception has a resonant coil, and

a side of said resonant coil facing said vehicle-mounted component has a region arranged at a constant distance from said vehicle-mounted component.

5. The vehicle according to claim 4, wherein

said resonant coil has a regular polygonal shape having as one side, said region arranged at the constant distance.

6. The vehicle according to claim 1, comprising a shielding member arranged around said electric power reception device between said vehicle-mounted component and said electric power reception device, wherein

said electric power reception device has a shape in conformity with an outer geometry of said shielding member.

7. The vehicle according to claim 1, wherein

said vehicle-mounted component includes a muffler or an exhaust pipe,

said electric power reception device includes a capacitor, and

at least a part of said electric power reception portion is located between said capacitor and said muffler or said exhaust pipe.

8. The vehicle according to claim 1, wherein

said vehicle-mounted component is a member selected from the group consisting of a side member, a rear suspension, a front suspension, a fuel tank, a fuel hose, a muffler, an exhaust pipe, a tire wheel, a vehicle height sensor, a brake, a brake hose, a battery, and a radiator.

9. The vehicle according to claim 1, wherein

a difference in natural frequency between said electric power transmission portion and said electric power reception portion is not higher than 10% of the natural frequency of said electric power reception portion.

10. The vehicle according to claim 1, wherein

a coefficient of coupling between said electric power reception portion and said electric power transmission portion is not greater than 0.1.

11. The vehicle according to claim 1, wherein

said electric power reception portion receives electric power from said electric power transmission portion through at least one of magnetic field formed between said electric power reception portion and said electric power transmission portion and oscillating at a specific frequency and electric field formed between said electric power reception portion and said electric power transmission portion and oscillating at a specific frequency.
