Abstract

A power receiving device, a power feeding device, and a wireless power transmission device are provided. The power receiving device receives power wirelessly transmitted from the power feeding device and includes one or more power receiving units. At least one of the power receiving units in the power receiving device is disposed along two or more surfaces which form the outer shape of the power receiving device and are not parallel to each other.

Claims

1. A power receiving device to which power is transmitted wirelessly from a power feeding device, comprising:

one or more power receiving units,

wherein at least one of the power receiving units is disposed along two or more surfaces which form the outer shape of the power receiving device and are not parallel to each other.

2. The power receiving device according to claim 1,

wherein power receiving faces of the power receiving unit are disposed along two or more surfaces which form the outer shape of the power receiving device and are not parallel to each other.

5. A wireless power transmission device comprising:

a power receiving device including a power receiving unit; and

a power feeding device including a power feeding unit,

wherein the power receiving device and the power feeding device are disposed so that at least a part of the power receiving unit and at least a part of the power feeding unit are opposed to each other, and

wherein at least one of the power receiving device and the power feeding device is the power receiving device according to claim 1 or the power feeding device which transmits power wirelessly to the power receiving device, comprising;

one or more power feeding units,

wherein at least one of the power feeding units is disposed along two or more surfaces which form the outer shape of the power feeding device and are not parallel to each other.

6. The wireless power transmission device according to claim 5,

wherein power feeding faces of the power feeding unit are disposed along two or more surfaces which form the outer shape of the power feeding device and are not parallel to each other.

7. The wireless power transmission device according to claim 5,

wherein power receiving faces of the power receiving unit are disposed along two or more surfaces which form the outer shape of the power receiving device and are not parallel to each other.

8. The wireless power transmission device according to claim 7,

wherein power feeding faces of the power feeding unit are disposed along two or more surfaces which form the outer shape of the power feeding device and are not parallel to each other.

3. A power feeding device which transmits power wirelessly to a power receiving device, comprising:

one or more power feeding units,

wherein at least one of the power feeding units is disposed along two or more surfaces which form the outer shape of the power feeding device and are not parallel to each other.

4. The power feeding device according to claim 3,

wherein power feeding faces of the power feeding unit are disposed along two or more surfaces which form the outer shape of the power feeding device and are not parallel to each other.
