Abstract

It includes an electricity receiving coil unit having an electricity receiving coil that generates heats due to electrical conduction thererof, an electric component storage box having a rectifier, and a harness electrically connecting the electricity receiving coil unit and the electric component storage box with each other. Part of the harness is routed in a vicinity of a front end of an upper face of the electricity receiving coil unit. Flows are made turbulent when traveling air hits the harness, and thereby airflows behind the harness turn into turbulence. Even if affixes such as mud fixate on the upper face of the electricity receiving coil unit, the affixes are removed by the turbulence.

Claims

1. A contactless charging device for a vehicle, comprising:

an electricity receiving coil unit having an electricity receiving coil that generates heats due to electrical conduction thererof;

an electric component storage box having at least a rectifier;

a first harness electrically connecting the electricity receiving coil unit and the electric component storage box with each other; and

a main harness,

wherein the electricity receiving coil unit, the electric component storage box, and the first harness are disposed beneath a floor panel of a vehicle body,

wherein at least part of the first harness is routed in a vicinity of a front end of an upper face of the electricity receiving coil unit, the front end being oriented toward a front of the vehicle,

wherein the electric component storage box is disposed above the upper face of the electricity receiving coil unit, and

wherein the main harness is routed such that the main harness passes between the upper face of the electricity receiving coil unit and the electric component storage box, and connects a battery and a motor with each other.

2. The contactless charging device for a vehicle according to claim 1, wherein

the first harness routed in the vicinity of the front end of the upper face of the electricity receiving coil unit is configured to include a vehicle width direction extending portion extending along a vehicle width direction as the part thereof.

3. The contactless charging device for a vehicle according to claim 1, wherein

a junction box that electrically connects the electricity receiving coil of the electricity receiving coil unit with the first harness extending from the electric component storage box is disposed at a front portion on the upper face of the electricity receiving coil unit.

4. The contactless charging device for a vehicle according to claim 1, wherein

the upper face of the electricity receiving coil unit is flat, and the upper face is an oblique face extending obliquely downward with respect to a horizontal plane of the vehicle body as extending toward a rear of the vehicle.

5. The contactless charging device for a vehicle according to claim 1, wherein

a plurality of protrusions protruding upward are disposed along a vehicle width direction at intervals at a front portion of the upper face of the electricity receiving coil unit.
