Abstract

A power receiving device of a contactless power supply configured in a wearable electronic device having a main body coupled to a wearing member, can include: a power receiving antenna including a receiving coil; a conducting wire of the receiving coil that substantially extends along a plane in which the wearing member and the main body are disposed; where the receiving coil is formed when the wearing member is coupled with the main body as a ring shape; and where an axial direction of the receiving coil passes through the ring shape.

Claims

1. A power receiving device of a contactless power supply configured in a wearable electronic device having a main body coupled to a wearing member, said power receiving device comprising:

a) a power receiving antenna comprising a receiving coil;

b) a conducting wire of said receiving coil that substantially extends along a plane in which said wearing member and said main body are disposed;

c) wherein said receiving coil is formed when said wearing member is coupled with said main body as a ring shape; and

d) wherein an axial direction of said receiving coil passes through said ring shape.

2. The power receiving device of claim 1, wherein:

a) said wearing member comprises a wearing portion and a connection portion, said wearing portion having one terminal coupled to said main body, and another terminal coupled to said main body through said connection portion in a detachable manner; and

b) said conducting wire of said receiving coil comprises a portion that extends on said wearing portion and said connection portion, said connection portion is configured to mechanically couple said wearing portion with said main body, and to electrically couple conducting wires of said wearing portion and said main body, in order to form said receiving coil.

3. The power receiving device of claim 2, wherein said connection portion comprises:

a) a plurality of conductive first connectors coupled to said conducting wire of said receiving coil disposed on said wearing portion;

b) a plurality of conductive second connectors that correspond to said first connectors, are coupled said conducting wire of said receiving coil disposed on said main body, and are adapted to couple with said first connectors in an interconnection manner; and

c) said first connectors being insulated from each other, and said second connectors being insulated from each other.

4. The power receiving device of claim 1, wherein said wearing member comprises:

a) first and second wearing portions coupled through said connection portion in a detachable manner; and

b) said receiving coil comprises a first portion disposed on said first wearing portion, a second portion disposed on said second wearing portion, and a third portion that extends to said connection portion, wherein said connection portion is configured to mechanically couple said first wearing portion to said second wearing portion, and to electrically couple corresponding conducting wires disposed on said first and second wearing portions, in order to form said receiving coil.

5. The power receiving device of claim 4, wherein said connection portion comprises:

a) a plurality of conductive first connectors coupled to said conducting wire of said receiving coil that is disposed on said first wearing portion;

b) a plurality of conductive second connectors that correspond to said first connectors, are coupled said conducting wire of said receiving coil disposed on said second wearing portion, and are adapted to couple with said first connectors in an interconnection manner; and

c) said first connectors being insulated from each other, and said second connectors being insulated from each other.

6. The power receiving device of claim 3, wherein said conductive first connectors comprise a plurality of optional connection locations, and are adapted to couple with corresponding said conductive second connectors in different locations.

7. The power receiving device of claim 3, wherein said conductive second connectors comprise a plurality of optional connection locations, and are adapted to couple with corresponding said first conductive connectors in different locations.
