Abstract

A vehicle capable of contactlessly receiving electric power is directed to suppress an electrical device carried by an operator from being affected by an electromagnetic field formed around a power reception unit. The vehicle includes: a connection portion to which an energy supply unit supplying energy is connected; and a power reception unit including a coil. The coil is formed to surround a winding axis extending in a horizontal direction. A first connection portion is provided at a position away from the winding axis.

Claims

1. A vehicle comprising:

a connection portion to which a supply unit that supplies energy is connected; and

a power reception unit that includes a coil and receives electric power contactlessly from a power transmission unit provided externally,

said coil being formed to surround a winding axis extending in a horizontal direction,

said connection portion being provided at a position away from said winding axis.

2. The vehicle according to claim 1, wherein said connection portion and said winding axis do not overlap with each other.

3. The vehicle according to claim 1, wherein

said vehicle has a circumferential surface and an upper surface, the circumferential surface including a plurality of surfaces,

said circumferential surface includes a first surface, a second surface facing said first surface, a third surface disposed between said first surface and said second surface, and a fourth surface disposed between said first surface and said second surface and facing said third surface,

said coil is disposed such that said winding axis passes through said third surface and said fourth surface, and

said connection portion is provided in one of said first surface, said second surface and said upper surface.

4. The vehicle according to claim 1, wherein

said vehicle has a circumferential surface including a plurality of surfaces, and an upper surface,

said circumferential surface includes a front surface, a rear surface, a first side surface, and a second side surface,

said coil is disposed such that said winding axis passes through said front surface and said rear surface, and

said connection portion is provided in said first side surface or said second side surface.

5. The vehicle according to claim 1, wherein said connection portion is provided at a position away from said winding axis and at a position away from said coil.

6. The vehicle according to claim 5, wherein

said vehicle has a circumferential surface including a plurality of surfaces,

said circumferential surface includes a first surface, a second surface facing said first surface, a third surface disposed between said first surface and said second surface, and a fourth surface disposed between said first surface and said second surface and facing said third surface, and

said connection portion is provided in one of said first surface, said second surface, said third surface, and said fourth surface that is farthest away from a center of said coil.

7. The vehicle according to claim 5, wherein

said vehicle has a circumferential surface and an upper surface, the circumferential surface including a plurality of surfaces,

said circumferential surface includes a front surface, a rear surface, a first side surface, and a second side surface,

said coil has a center located at a position close to said rear surface relative to said front surface, and

said connection portion is provided in said first side surface or said second side surface, and disposed at a position close to said front surface relative to said rear surface.

8. The vehicle according to claim 7, wherein

said vehicle includes a passenger compartment capable of housing a passenger, a boarding opening communicating with said passenger compartment, and a door that opens/closes said boarding opening, and

said connection portion is provided at a front side relative to said door.

9. The vehicle according to claim 1, wherein

said vehicle further includes a battery, and

said battery is provided to overlap with said winding axis.

10. The vehicle according to claim 9, wherein

said battery is longer in a direction in which said winding axis extends than in a direction perpendicular to said winding axis.

12. The vehicle according to claim 1, wherein

said vehicle has a circumferential surface and an upper surface, the circumferential surface including a plurality of surfaces,

said circumferential surface includes a first surface, a second surface facing said first surface, a third surface disposed between said first surface and said second surface, and a fourth surface disposed between said first surface and said second surface and facing said third surface,

said coil is disposed such that said winding axis passes through said third surface and said fourth surface, and

said connection portion is provided in said upper surface and disposed near said first surface or said second surface.

13. The vehicle according to claim 1, wherein

said vehicle has a circumferential surface and an upper surface, the circumferential surface including a plurality of surfaces,

said circumferential surface includes a first surface, a second surface facing said first surface, a third surface disposed between said first surface and said second surface, and a fourth surface disposed between said first surface and said second surface and facing said third surface,

said connection portion is provided in said upper surface, and

assuming that one of said first surface, said second surface, said third surface, and said fourth surface that is farthest away from a center of said coil is defined as a farthest surface, said connection portion is provided at a position in said upper surface near said farthest surface.

said connection portion includes a charging portion to which a power supply plug that supplies electric power is connected;

and an energy supply unit to which a supply plug that supplies energy different from electric power is connected, and

said energy supply unit is provided at a position farther away from said coil than said charging portion.

15. The vehicle according to claim 1, wherein

said connection portion includes a charging portion to which a power supply plug that supplies electric power is connected;

and an energy supply unit to which a supply plug that supplies energy different from electric power is connected, and

said charging portion is provided at a position farther away from said coil than said energy supply unit.

16. The vehicle according to claim 1, wherein said power reception unit is provided at a bottom surface of the vehicle.
