Abstract

The present invention provides a mobile apparatus with wireless charging function and an accessory apparatus with wireless charging function capable of allowing a wireless power receiver (PRX) to communicate with a CPU of a mobile device, so as to solve the problem mentioned above. The mobile apparatus comprises: a processing circuit and a wireless power receiver (PRX). The PRX is coupled to the processing circuit and wirelessly connected to a wireless power transmitter (PTX) of a wireless charger, for receiving a wireless power, wherein the PRX receives a first authentication request signal from the PTX and then sends a second authentication request signal to the processing circuit, and the processing circuit sends a second authentication information to the PRX, and the PRX sends a first authentication information to the PTX.

Claims

1. A mobile apparatus with wireless charging function, comprising:

a processing circuit; and

a wireless power receiver (PRX) of the mobile apparatus, coupled to the processing circuit of the mobile apparatus and wirelessly connected to a wireless power transmitter (PTX) of a wireless charger, for receiving a wireless power, wherein the PRX receives a first authentication request signal from the PTX and then sends a second authentication request signal related to the first authentication request signal and comprising an ID of the PRX to the processing circuit, and in response to the second authentication request signal the processing circuit sends a second authentication information to the PRX, the second authentication information comprising a password and the ID of the PRX, and in response to the first authentication request signal and the second authentication information the PRX sends a first authentication information to the PTX, the first authentication information comprising the password;

wherein the wireless charger determines to continue or stop providing power to the mobile apparatus according to the password.

2. The mobile apparatus of claim 1, further comprising:

a communication circuit, coupled to the processing circuit, for sending a third authentication request signal related to the second authentication request signal and the first authentication request signal and comprising an ID of the mobile apparatus to a first server not coupled to the wireless charger, wherein the first server sends a third authentication information according to the third authentication request signal to the communication circuit, the third authentication information comprising the password, the ID of the PRX and the ID of the mobile apparatus.

3. The mobile apparatus of claim 1, wherein the wireless charger further comprises a processing circuit, and the processing circuit controls the wireless charger whether to keep or stop providing the wireless power, or adjust a power level of the wireless power according to the first authentication information.

4. The mobile apparatus of claim 3, wherein the wireless charger is integrated in a light device or an electronic device, and the processing circuit controls the light device or the electronic device according to the first authentication information.

5. The mobile apparatus of claim 1, wherein the wireless charger further comprises a communication circuit for sending the first authentication information to a second server, and the second server responds with a feedback signal to the wireless charger.

6. The mobile apparatus of claim 5, wherein the second server responds with the feedback signal to control the wireless charger whether to keep or stop providing the wireless power, or adjust a power level of the wireless power according to the first authentication information.

7. The mobile apparatus of claim 5, wherein the wireless charger is integrated in a light device or an electronic device, and the second server responds with the feedback signal to control the light device or the electronic device according to the first authentication information.

8. The mobile apparatus of claim 5, wherein the first server and the second server are one and the same.

9. The mobile apparatus of claim 1, wherein the PRX is coupled to the processing circuit via a bus.

10. The mobile apparatus of claim 1, wherein the processing circuit further comprises:

a processor, a memory, and a communication circuit.
