Abstract

A power transmitting device includes a power transmitting unit. The power transmitting unit is configured to transmit power through wireless power supply to a power receiving device disposed in a cabin of a mobile unit. At least one front seat and a rear seat are provided in the cabin to be aligned in a front-rear direction of the mobile unit. The interior of the cabin includes a first region that includes a region in which the front seat is disposed and a region on a front side, and a second region that includes a region in which the rear seat is disposed and a region on a rear side. The power transmitting unit is disposed such that a central axis of a power transmittable range in which the power can be transmitted is contained within the second region.

First claim

What is claimed is:

1 . A power transmitting device, comprising a power transmitting unit configured to transmit power through wireless power supply to a power receiving device disposed in a cabin of a mobile unit, wherein
at least one front seat and a rear seat are provided in the cabin so as to be aligned in a front-rear direction of the mobile unit, the at least one front seat including a driver's seat, an interior of the cabin includes:
a first region that includes a region in which the at least one front seat is disposed and a region on a front side in the front-rear direction; and
a second region that includes a region in which the rear seat is disposed and a region on a rear side in the front-rear direction, and
the power transmitting unit is disposed such that a central axis of a power transmittable range in which the power can be transmitted is contained within the second region.

2 . The power transmitting device according to claim 1 , wherein the power transmitting unit is provided on a ceiling of the mobile unit such that the power transmitting unit is disposed on a front side relative to a middle position in the front-rear direction in the second region, and the central axis extends obliquely downward and obliquely rearward from the power transmitting unit as a starting point in the movable unit.

3 . The power transmitting device according to claim 2 , wherein
the mobile unit includes an interior light unit that is provided on the ceiling and configured to illuminate the interior of the cabin, and the power transmitting unit is integrated with the interior light unit.

4 . The power transmitting device according to claim 1 , wherein the power transmitting unit is provided on a side wall of the cabin.

5 . The power transmitting device according to claim 1 , further comprising a reflecting portion configured to reflect power transmitted from the power transmitting unit,
wherein the reflecting portion is attached to a component disposed inside the cabin in a state in which an outer surface of the reflecting portion is covered with an interior member so as not to be exposed to the interior of the cabin.

6 . The power transmitting device according to claim 5 , wherein
the at least one front seat includes the driver's seat and a front passenger seat provided on a side of the driver's seat, and the reflecting portion is disposed between the driver's seat and the front passenger seat.
