Abstract

A portable terminal according to the present disclosure may include an information display part including a display screen displaying information and a battery; and a band part fastened to the information display part, wherein the band part includes a charging coil wirelessly receiving power to transfer the power to the battery.

Claims

1. A portable terminal comprising:

an information display part including a display screen displaying information and a battery; and

a band part fastened to the information display part,

wherein the band part includes a charging coil wirelessly receiving power to transfer the power to the battery.

2. The portable terminal of claim 1, wherein the band part includes at least one through hole, and the charging coil is disposed in a spiral manner, based on the at least one through hole.

3. The portable terminal of claim 2, wherein the band part includes a fastening member provided at one end thereof, and

the band part is formed to have a ring shape capable of being worn on a wrist by the coupling of fastening member and the at least one through hole.

4. The portable terminal of claim 1, wherein the charging coil is formed in the manner of a board to thereby be embedded in the band part.

5. The portable terminal of claim 1, wherein the charging coil is formed in the manner of a wire to thereby be embedded in the band part.

6. The portable terminal of claim 2, wherein the band part includes a plurality of through holes, and the charging coil is disposed in a spiral manner, around a circumference of each of the plurality of through holes.

7. The portable terminal of claim 6, wherein the charging coils disposed around the circumference of each of the plurality of through holes are connected in parallel to each other.

8. The portable terminal of claim 6, wherein the charging coils disposed around the circumference of each of the plurality of through holes are connected in series to each other.

9. The portable terminal of claim 2, wherein the band part further includes an auxiliary hole disposed between each of the plurality of through holes.

10. A wireless charging device comprising:

a core part including upper and lower cores;

a protrusion part protruding from at least one of the upper and lower cores; and

a transmission coil disposed in a spiral manner, based on the protrusion part.

11. The wireless charging device of claim 10, wherein in the core part, the upper and lower cores are coupled to each other in a manner in which a distal end of the protrusion part comes into surface-contact with the core part.

12. The wireless charging device of claim 10, wherein the protrusion part is formed from the lower core, and the upper core is formed to have a flat plate shape.

13. The wireless charging device of claim 10, wherein the protrusion part is formed from each of the upper and lower cores, and in the core part, the upper and lower cores are coupled to each other in a manner in which distal ends of the protrusion parts come into surface-contact with each other.

14. The wireless charging device of claim 10, wherein the protrusion part is formed from each of the upper and lower cores, and in the core part, the upper and lower cores are coupled to each other in a manner in which the protrusion parts are offset from each other.

15. The wireless charging device of claim 10, wherein the transmission coil is formed in the manner of a coil board or wire.

16. A wireless charging structure comprising:

a wireless charging device including upper and lower cores, a protrusion part protruding from at least one of the upper and lower cores, and a transmission coil disposed in a spiral manner, based on the protrusion part; and

a portable terminal interposed between the upper and lower cores so that the protrusion part is inserted into a through hole formed therein,

wherein in the portable terminal, a charging coil is disposed around a circumference of the through hole.

17. A wireless charging structure comprising:

a wrist wearable portable terminal including a charging coil embedded in a band part; and

a wireless charging device in which the band part of the portable terminal is interposed between upper and lower cores, and power is wirelessly transmitted to the charging coil through a transmission coil disposed on the upper or lower core.

18. The wireless charging structure of claim 17, wherein the band part includes at least one through hole formed therein, and

at least one of the upper and lower cores includes a protrusion part inserted into the at least one through hole.

19. The wireless charging structure of claim 18, wherein the charging coil is disposed around a circumference of the at least one through hole, and the transmission coil is disposed around a circumference of the protrusion part.
