Abstract

According to various embodiments, a wireless charging device can comprise: a first housing, which includes a first surface facing a first direction and a second surface facing a second direction opposite to the first direction, and includes at least one hole; a second housing arranged on the second surface of the first housing in the second direction; a coil unit arranged between the first housing and the second housing and configured to transmit power to an external device; a shielding member arranged adjacent to the coil unit and including at least one hole; and a fan arranged adjacent to the coil unit and configured to rotate.

Claims (32)

1. A wireless charging device comprising:

a first housing, which comprises a first surface facing a first direction and a second surface facing a second direction opposite to the first direction, and includes at least one hole;

a second housing arranged along the second direction on the second surface of the first housing;

a coil unit arranged between the first housing and the second housing, and configured to transmit power to an external device;

a shielding member arranged adjacent to the coil unit, and comprising a plurality of holes; and

a fan arranged adjacent to the coil unit and configured to rotate,

wherein a portion of the plurality of holes is superimposed over the coil unit.

2. The wireless charging device of claim 1 , wherein the fan receives external air through the at least one hole of the first housing and the at least one hole of the shielding member.

3. The wireless charging device of claim 1 , wherein a pad is further arranged on the first surface of the first housing, and

the pad comprises at least one protrusion protruded in the first direction.

4. The wireless charging device of claim 3 , wherein the first housing is configured to safely mount the external device on the first surface.

5. The wireless charging device of claim 4 , wherein the at least one protrusion provides a space between the first surface of the first housing and the external device.

6. The wireless charging device of claim 1 , further comprising a third housing arranged between the first housing and the second housing,

wherein the third housing comprises a first surface facing the first direction, a second surface facing the second direction, and a hole passing through the first surface and the second surface.

7. The wireless charging device of claim 6 , wherein the third housing comprises a third surface facing a third direction which intersects with the first direction and the second direction, and

comprises at least one hole provided in the third surface.

8. The wireless charging device of claim 7 , wherein the fan receives external air through the at least one hole provided in the third surface.

9. The wireless charging device of claim 7 , wherein the third housing comprises a fourth surface facing a fourth direction which intersects with the first direction, the second direction and the third direction, and

comprises at least one hole provided in the fourth surface.

10. The wireless charging device of claim 9 , wherein the at least one hole provided in the fourth surface forms an air channel for discharging out air introduced into the wireless charging device.

11. The wireless charging device of claim 1 , further comprising a guide arranged between the first housing and the second housing, and configured to support the external device.

12. The wireless charging device of claim 11 , wherein the guide comprises at least one hole, and

air is introduced through the at least one hole of the guide and is forwarded to the fan.

13. The wireless charging device of claim 1 , further comprising a bracket which supports the coil unit and the shielding member,

wherein the bracket comprises a hole provided in the second direction.

14. The wireless charging device of claim 13 , wherein the fan receives external air through the hole provided in the second direction in the bracket.

15. The wireless charging device of claim 13 , wherein the bracket comprises a hole provided in a fourth direction.

16. The wireless charging device of claim 15 , wherein the hole provided in the fourth direction forms an air channel for discharging out air introduced into the wireless charging device.

17. The wireless charging device of claim 11 , wherein the guide is configured to move in a third direction which intersects with the first direction and the second direction.

18. The wireless charging device of claim 11 , wherein the guide includes a guide arm extended in the first direction.

19. The wireless charging device of claim 11 , wherein the guide includes at least any one of portions of different thicknesses.

20. The wireless charging device of claim 11 , wherein, a portion close to the first housing in the guide is smaller in thickness than a portion distant from the first housing.
