Abstract

A wireless charging device which locates a portable electronic device for efficient charging while providing a secure, stable and usable platform for the portable electronic device.

Claims

1. A device for providing power to a portable device comprising:

a base housing having a circumferential outer extent configured to fit within a cup holder in a vehicle and a longitudinal axis and wherein said base housing includes a base;

a top housing having a top surface and a front lip and wherein said top surface is angled relative to said longitudinal axis between being parallel to said longitudinal axis and perpendicular to said longitudinal axis and wherein said top surface is closer to said base proximate to said front lip than said top surface is to said base remote from said front lip; and

a primary charging unit including a charging circuit and a primary coil for inductively providing power.

2. The device of claim 1 wherein said top surface further includes a locating mechanism.

3. The device of claim 2 wherein said locating mechanism includes a recessed surface and two locating edges.

4. The device of claim 1 wherein said top housing includes an outer lip and said top surface includes a locating mechanism having a recessed surface and wherein said recessed surface extends from said front lip to the opposing portion of said outer lip.

5. The device of claim 4 wherein said outer lip defines at least a portion of said front lip.

6. The device of claim 1 wherein said front lip includes a rest surface approximately perpendicular to said top surface.

7. The device of claim 1 wherein said primary charging unit includes a power cord extending therefrom.

8. The device of claim 7 wherein said power cord includes a plug.

9. The device of claim 8 wherein said plug is a cigarette lighter plug.

10. The device of claim 8 wherein said plug is located in the base of said base housing and wherein said cup holder includes an electrical connection configured to interface with said plug and provide power to said primary charging unit.

11. The device of claim 8 wherein said base housing includes a inductive power receiving device configured to receive inductive power from said cup holder.

12. The device of claim 1 wherein said primary coil includes a flat surface and is located in close proximity to said top surface and wherein the said flat surface is configured to be approximately parallel to said top surface.

13. The device of claim 1 further include a fit insert, said fit insert designed to provide a secure fit between said cup holder and said base housing.

14. The device of claim 1 wherein said top surface includes friction pads.

15. The device of claim 1 further including an adaptor to interface between the device and the portable device.

16. The device of claim 15 wherein said adaptor is configured to fit within a recessed area on the top surface.

17. The device of claim 1 wherein said portable device is any electronic device having a rechargeable battery.
