Wireless input device, charging pad and charging method thereof
First Claim
1. A wireless input device, comprising:
- a rechargeable wireless mouse;
a wireless receiver; and
a charging pad configured to wirelessly charge said rechargeable wireless mouse, comprising;
a wireless power transmitting module;
a charging control circuit electrically connected to said wireless power transmitting module, said charging control circuit activating said wireless power transmitting module to wirelessly output an electromagnetic power according to an activation signal provided by said wireless receiver;
wherein said charging pad receives said activation signal when said wireless receiver is connected to said charging pad, and said charging control circuit stops said wireless power transmitting module from wirelessly outputting the electromagnetic power when said charging pad is not connected to said wireless receiver;
wherein when the rechargeable wireless mouse is placed on the charging pad, the rechargeable wireless mouse outputs a charging signal to the wireless receiver, and the wireless receiver outputs a working signal to the charging control circuit according to the charging signal;
wherein when the wireless receiver is connected to the charging pad and the charging control circuit determines that the rechargeable wireless mouse is not placed on the charging pad in response to receiving none of the working signal, the charging control circuit controls the wireless power transmitting module to intermittently output the electromagnetic power wirelessly such that the charging pad charges the rechargeable wireless mouse in an energy-saving mode;
wherein when the wireless receiver is connected to the charging pad and the charging control circuit determines that the rechargeable wireless mouse is placed on the charging pad in response to receiving the working signal, the charging control circuit controls the wireless power transmitting module to continuously output the electromagnetic power wirelessly such that the charging pad charges the rechargeable wireless mouse in a working mode.

Abstract
A wireless input device is provided. The wireless input device includes a rechargeable wireless mouse, a wireless receiver and a charging pad. The charging pad includes a wireless power transmitting module and a charging control circuit. The charging control circuit is electrically connected to the wireless power transmitting module. The charging control circuit correspondingly activates the wireless power transmitting module to wirelessly output the electromagnetic power according to an activation signal provided by the wireless receiver. The charging pad receives the activation signal when the wireless receiver is connected to the charging pad. When the charging pad is not connected to the wireless receiver, the charging control circuit stops the wireless power transmitting module from wirelessly outputting the electromagnetic power. Accordingly, the charging pad of the present invention can avoid damage resulting from the abnormal charging so as to save power.
