Abstract

A wireless charging device includes an external cover to be disposed in an interior of a vehicle, a wireless charging module disposed in the external cover, and an elastic support disposed on a surface of the external cover to elastically support a power receiving apparatus removably inserted between the external cover and the elastic support.

First claim

What is claimed is:

1. A wireless charging device, comprising:
an external cover to be disposed in an interior of a vehicle, a wireless charging module disposed in the external cover; and
an elastic support disposed on a surface of the external cover to elastically support a power receiving apparatus removably inserted between the external cover and the elastic support, and
a magnetic part attached to an inner surface of the elastic support,
wherein the elastic support is configured to press the power receiving apparatus to contact the surface of the external cover when the power receiving apparatus is receiving power transmitted by the wireless charging module,
wherein the elastic support comprises:
a fastening portion fastened to the external cover;
an elastic portion extending from the fastening portion to elastically support the power receiving apparatus; and
a plurality of catching jaws protruding from the inner surface of the elastic portion, the plurality of catching jaws supporting a lower surface of the portable terminal to prevent the portable terminal from dropping into the bottom of the charging space formed between the elastic support and the external cover.

2. The wireless charging device of claim 1 , wherein the fastening portion is fastened to the external cover to be perpendicular to the surface of the external cover.

3. The wireless charging device of claim 1 , wherein the fastening portion is fastened to the external cover to be parallel to a rotational axis of the external cover.

4. The wireless charging device of claim 1 , wherein the fastening portion is fastened to the external cover to be perpendicular to a rotational axis of the external cover.

5. The wireless charging device of claim 1 , wherein the elastic portion is configured to be disposed adjacent to the external cover and extends from the fastening portion towards the surface of the external cover.

6. The wireless charging device of claim 1 , wherein the elastic portion is configured to elastically support the power receiving apparatus by contacting a surface of the power receiving apparatus.

7. The wireless charging device of claim 1 , wherein the elastic support further comprises an extended part that extends from the elastic portion, the extended part being configured to be disposed away from the external cover.

8. The wireless charging device of claim 1 , further comprising guide blocks respectively disposed along both sides of the elastic support on the surface of the external cover.

9. The wireless charging device of claim 1 , wherein the magnetic part comprises a ferritic sheet.

10. The wireless charging device of claim 1 , wherein the wireless charging module comprises:
a coil part comprising at least one coil; and
a circuit part electrically connected to the coil part to control power applied to the coil part.

11. The wireless charging device of claim 10 , wherein the coil part and the circuit part have thin plate shapes, respectively, and are embedded in the external cover in a state in which the coil part and the circuit part overlap each other.

12. A wireless charging device for a vehicle, comprising:
an external cover opening or closing an opening of an accommodation space;
an elastic support configured to elastically support a power receiving apparatus removably inserted between a surface of the external cover and the elastic support; and
a wireless charging module disposed in the external cover and configured to wirelessly transmit power to the wireless receiving apparatus,
wherein the elastic support comprises;
a fastening portion fastened to the external cover,
an elastic portion extending from the fastening portion to elastically support the power receiving apparatus,
a magnetic part attached to an inner surface of the elastic portion, and
a plurality of catching jaws protruding from the inner surface of the elastic portion, the plurality of catching jaws supporting a lower surface of the portable terminal to prevent the portable terminal from dropping into the bottom of the charging space formed between the elastic support and the external cover.

13. The wireless charging device of claim 12 , wherein the elastic support is configured to support the power receiving apparatus so that a surface of the power receiving apparatus contacts the external cover when the wireless charging module is transmitting power to the wireless receiving apparatus.
