Abstract

A wireless charging device for a vehicle includes an external cover configured to be pivotally connected to an interior of a vehicle and including a wireless charger within the external cover; an internal cover movably connected to an inner surface of the external cover and configured to elastically support a power receiving device receiving electrical power transmitted by the wireless charging module; and at least one elastic joint elastically connecting the internal cover to the external cover.

Claims

1. A wireless charging device for a vehicle, comprising:

an external cover configured to be pivotally connected to an interior of a vehicle and including a wireless charger within the external cover;

an internal cover movably connected to an inner surface of the external cover and configured to elastically support a power receiving device receiving electrical power transmitted by the wireless charging module; and

at least one elastic joint elastically connecting the internal cover to the external cover.

2. The wireless charging device for a vehicle of claim 1, wherein the elastic joint is formed of a coil spring, one end of the elastic joint is connected to the external cover, and the other end of the elastic joint is connected to the internal cover.

3. The wireless charging device for a vehicle of claim 1, wherein the internal cover is provided with at least one cut-out portion formed adjacently to an entrance into which the power receiving device is inserted.

4. The wireless charging device for a vehicle of claim 1, wherein the external cover comprises a pair of side portions protruding from edges of a surface of the external cover toward the internal cover.

5. The wireless charging device for a vehicle of claim 4, wherein the side portions of the external cover are disposed perpendicular to a pivot axis of the external cover.

6. The wireless charging device for a vehicle of claim 4, wherein the internal cover comprises a pair of side portions protruding toward the external cover.

7. The wireless charging device for a vehicle of claim 1, wherein the internal cover is in surface contact with the power receiving device and is configured to elastically support the power receiving device.

8. The wireless charging device for a vehicle of claim 1, further comprising a magnetic portion attached to an inner surface of the internal cover.

9. The wireless charging device for a vehicle of claim 8, wherein the magnetic portion is configured of a ferrite sheet.

10. The wireless charging device for a vehicle of claim 1, wherein the wireless charger comprises a coil portion including at least one coil, and a circuit portion electrically connected to the coil portion to control electrical power applied to the coil portion.

11. The wireless charging device for a vehicle of claim 10, wherein the coil portion and the circuit portion are provided in a form of a planar plate, and embedded in the external cover in an overlapping state.

12. A wireless charging device for a vehicle comprising:

an external cover configured to open or close an entrance of a storage space;

an internal cover elastically connected to the external cover and configured to elastically support a power receiving device to maintain the power receiving device in surface contact with a surface of the external cover; and

a wireless charger disposed within the external cover and configured to wirelessly transmit electrical power to the power receiving device.
