Abstract
A power supply device of the present invention includes a power transmission unit (15) configured to wirelessly supply power to the power receiving unit (9). The power transmission unit (15) includes: a ground-side coil (13); and a housing (21) set on a ground (19) and configured to house the ground-side coil (13). The housing (21) includes: a coil section (25) in which to dispose the ground-side coil (13); and a first projection (29) disposed closer to a vehicle entry side than the ground-side coil (13) is, and projecting upward from a surface of the coil section (25).
Claims11
A power supply device comprising:
- a power receiving unit including a vehicle-side coil, the power receiving unit being mounted on a vehicle;
- and
- a power transmission unit configured to wirelessly supply power to the power receiving unit, wherein
- the power transmission unit includes
- a ground-side coil, and
- a housing set on a ground and configured to house the ground-side coil, and
- the housing includes
- a cover located above the ground-side coil and made of a non-conducting material, and
- a first projection disposed closer to a vehicle entry side than the cover is, and projecting upward from a surface of the cover,
- wherein the power transmission unit is configured to wirelessly supply power to the power receiving unit when the housing is located at a position with respect to which a pair of tires of the vehicle are left-right symmetric, and
- wherein the first projection includes a run-onto blocking portion configured to prevent a tire of the vehicle from running onto the cover.
A power transmission unit for a power supply device configured to wirelessly supply power to a power receiving unit including a vehicle-side coil, the power receiving unit being mounted on a vehicle, comprising:
- a ground-side coil, and
- a housing set on a ground and configured to house the ground-side coil, wherein the housing includes
- a cover located above the ground-side coil and made of a non-conducting material, and
- a projection disposed closer to a vehicle entry side than the cover is, and projecting upward from a surface of the cover,
- wherein the power transmission unit is configured to wirelessly supply power to the power receiving unit when the housing is located at a position with respect to which a pair of tires of the vehicle are left-right symmetric, and
- wherein the projection includes a run-onto blocking portion configured to prevent a tire of the vehicle from running onto the cover.
A power supply device comprising:
- a power receiving unit including a vehicle-side coil;
- and
- a power transmission unit configured to wirelessly supply power to the power receiving unit, wherein
- the power transmission unit includes
- a ground-side coil, and
- a housing set on a ground and configured to house the ground-side coil, and
- the housing includes
- a cover located above the ground-side coil and made of a non-conducting material, and
- a first projection disposed closer to a vehicle entry side than the cover is, and projecting upward from a surface of the cover,
- the housing includes a second projection, which projects upward from the surface of the cover, at a position opposite the first projection with the cover interposed in between,
- one of the first and second projections includes a transmitter of a foreign object detection signal for detecting a foreign object on the cover, and
- the other of the first and second projections includes a receiver configured to receive the foreign object detection signal transmitted from the transmitter.
