Abstract

A vehicle includes a power reception device which receives electric power from a power transmission device in a non-contact manner. The power reception device can be mounted on a bottom surface side of the vehicle. An accommodation space of the power reception device is defined between a base and a protective cover. Within the apparatus accommodation space of the power reception device is a frame that has a plurality of radial ribs extending radially from a center of the frame toward an outer peripheral portion of the frame. In addition, a side of an apparatus within the accommodation space closer to the vehicle abuts on the base, and a side of the apparatus opposite to the vehicle abuts on the protective cover.

Claims

1. A vehicle comprising a power reception device, disposed on a bottom surface side of the vehicle, the power reception device configured to receive electric power from a power transmission device in a non-contact manner, the power reception device including:

a base arranged on the bottom surface side of the vehicle, a protective cover which defines an apparatus accommodation space between the base and the protective cover,

a frame arranged in the apparatus accommodation space and provided with an open region at a center of the frame, a first side of the frame facing toward the base, a second opposite side of the frame facing toward the protective cover,

a power reception coil provided on the second side of the frame and in the apparatus accommodation space and surrounding the open region, and

an apparatus arranged in the open region and in the apparatus accommodation space,

wherein

the frame has a plurality of radial ribs extending radially from the center toward an outer peripheral portion of the frame, and

a first side of the apparatus closer to the vehicle abuts on the base and a second side of the apparatus opposite to the first side of the apparatus abuts on the protective cover.

2. The vehicle according to claim 1, wherein

the power reception device further includes a ferrite core,

the frame includes an annular rib that surrounds the open region and overlaps with the ferrite core when viewed in a plan view, and

the plurality of radial ribs extend outward from the annular rib.

3. The vehicle according to claim 1, wherein the apparatus is a filter circuit coil.

4. The vehicle according to claim 1, wherein

a battery pack is arranged on the bottom surface side of the vehicle, and

the base is arranged on the battery pack.

5. The vehicle according to claim 1, wherein the base includes a protruding portion at a central region of the base, and the first side of the apparatus abuts on the protruding portion.

6. The vehicle according to claim 1, wherein

the power reception device further includes an inner ferrite core that surrounds the open region, and an outer ferrite core that surrounds the inner ferrite core,

the frame includes a first step portion on which the inner ferrite core is mounted, and a second step portion on which the outer ferrite core is mounted, and

the first step portion protrudes relative to the second step portion so as to be farther from the base than the second step portion.

7. The vehicle according to claim 6, wherein the power reception coil is disposed over the outer ferrite coil.
