Abstract

An adaptor for converting a conventional electronic device into one capable of being charged by a contactless charger is provided. The adaptor has a base member that couples to the electronic device, and a sliding member that includes a contact block for electrically coupling the adaptor to the electronic device. The base member includes a contactless pick-up coil for receiving energy from a conatactless charger. The base member is coupled to the electronic device, and the sliding member is moved from an extended position to a retracted position, thereby coupling the electrical contacts of the contact block to a charging receptacle on the electronic device.

Claims

1. An adaptor to facilitate contactless charging in an electronic device, the adaptor comprising:

a. a base member comprising a contactless charging pick-up coil; and

b. a coupling member comprising an electrical connector for coupling to the electronic device;

wherein the coupling member is capable of mechanically sliding from a first, extended position to a second, retracted position.

2. The adaptor of claim 1, further comprising electronic circuitry coupled to the contactless charging pick-up coil and the electrical connector.

3. The adaptor of claim 2, wherein the electronic circuitry comprises charging circuitry for charging a rechargeable battery.

4. The adaptor of claim 1, wherein the base member comprises a mechanical connector for attaching to the electronic device.

5. The adaptor of claim 1 or 2, wherein when the adaptor is coupled to the electronic device, the contactless charging pick-up coil is electrically coupled to a rechargeable battery of the electronic device.

6. The adaptor of claim 1 or 2, wherein when the adaptor is coupled to the electronic device, the contactless charging pick-up coil is coupled to charging circuitry disposed within the electronic device.

7. The adaptor of claim 4, wherein the electronic device is selected from the group consisting of telephones, pagers, personal digital assistants, MP3 players, portable computers, two-way radios and electronic games.

8. The adaptor of claim 1, wherein the base member comprises a battery door.

9. A contactless charging adaptor for an electronic device, comprising:

a. a base member capable of mechanically coupling to the electronic device, wherein the base member comprises a pick-up coil; and

b. a sliding member comprising a contact block capable of mating with an electrical receptacle of the electronic device.

10. The adaptor of claim 9, wherein the sliding member is capable of mechanically moving from a first, extended position to a second, retracted position.

11. The adaptor of claim 10, further comprising electronic circuitry coupled to the contactless charging pick-up coil and the electrical connector.

12. The adaptor of claim 11, wherein the electronic circuitry comprises charging circuitry for charging a rechargeable battery.

13. The adaptor of claim 9, wherein the base member comprises a mechanical connector for attaching to the electronic device.

14. The adaptor of claim 13, wherein when the adaptor is coupled to the electronic device, the contactless charging pick-up coil is electrically coupled to a rechargeable battery of the electronic device.

15. The adaptor of claim 13, wherein when the adaptor is coupled to the electronic device, the contactless charging pick-up coil is coupled to charging circuitry disposed within the electronic device.

16. The adaptor of claim 13, wherein the electronic device is selected from the group consisting of telephones, pagers, personal digital assistants, MP3 players, portable computers, two-way radios and electronic games.

17. The adaptor of claim 9, wherein the base member comprises a battery door.
