Abstract

An embodiment provides an electronic device comprising: a body; a battery disposed within the body; a first portion extending from the body; a second portion extending from the body; and a charging coil disposed within at least the first portion and the second portion that charges the battery. Other aspects are described and claimed.

First claim

What is claimed is:

1. An electronic device comprising:
a body;
a plurality of electronic components disposed within the body, wherein the plurality of electronic components comprise a battery;
a first portion extending from the body;
a second portion extending from the body;
a shielding layer covering the plurality of electronic components disposed within the body; and
a charging coil disposed within the body, the first portion, and the second portion that charges the battery, wherein the charging coil is positioned at an inner peripheral edge of the first portion and the second portion;
wherein a conductive line of the charging coil has a deformable helical shape and surrounds the inner peripheral edge of the first portion and the second portion, the conductive line being formed from a plurality of parallel, butt-jointed terminals located inside the conductive line.

2. The electronic device of claim 1 , wherein the first portion and the second portion attach to one another at an ends thereof distal to the body.

3. The electronic device of claim 2 , wherein an annular space is formed by the body, the first portion and the second portion when the first portion is attached with the second portion.

4. The electronic device of claim 3 , wherein the first portion and the second portion form a watch band.

5. The electronic device of claim 2 , wherein the first portion and the second portion attach via an interface.

6. The electronic device of claim 1 , wherein the first portion and the second portion are deformable.

7. The electronic device according to claim 1 , wherein the body comprises a main-board.

8. The electronic device of claim 1 , wherein the electronic device is a smart watch.

9. A method, comprising:
attaching a first deformable portion and a second deformable portion to a body of an electronic device, wherein the body comprises a plurality of electronic components, the plurality of electronic components comprising a battery; and
connecting a charging coil disposed in the body, the first portion and the second portion to a charging chip within the body of the electronic device, wherein the charging coil is positioned at an inner peripheral edge of the first portion and the second portion;
wherein a conductive line of the charging coil has a deformable helical shape and surrounds the inner peripheral edge of the first portion and the second portion, the conductive line being formed from a plurality of parallel, butt-jointed terminals located inside the conductive line.

10. The method of claim 9 , wherein the first portion and the second portion attach to one another at an ends thereof distal to the body.

11. The method of claim 10 , wherein an annular space is formed by the body, the first portion and the second portion when the first portion is attached with the second portion.

12. The method of claim 9 , wherein the first portion and the second portion attach via an interface.

13. The method of claim 9 , wherein the first portion and the second portion form a watch band.

14. The method of claim 9 , wherein the body comprises a main-board attached to the charging chip.

15. The method of claim 9 , comprising providing a shielding layer.

16. The method of claim 15 , wherein the providing comprises disposing the shielding layer within the body of the electronic device.

17. A system, comprising:
an electronic device comprising a body; a battery disposed within the body; a first portion extending from the body; a second portion extending from the body; and a charging coil disposed within the body, the first portion and the second portion that charges the battery, wherein the charging coil is positioned at an inner peripheral edge of the first portion and the second portion; and
a charger that transfers a charge to the charging coil;
wherein the body comprises a plurality of electronic components, the plurality of electronic components comprising a battery;
wherein a conductive line of the charging coil has a deformable helical shape and surrounds the inner peripheral edge of the first portion and the second portion, the conductive line being formed from a plurality of parallel, butt-jointed terminals located inside the conductive line.

18. The system of claim 17 , wherein the charger transfers the charge wirelessly.

19. The system of claim 17 , wherein the electronic device is a smart watch.
