WIRELESS CHARGING DEVICE AND ELECTRONIC DEVICE ASSEMBLY WITH WIRELESS CHARGING DEVICE
First Claim
1. A wireless charging device charging for an electronic device, the wireless charging device comprising:
- a control unit;
a sending coil coupled to the control unit, the sending coil configured to generate an induced magnetic field to charge an electronic device; and
a range sensor coupled to the control unit, the range sensor configured to sense a distance between a user and the wireless charging device, the range sensor further configured to determine if the sensed distance is greater than a preset distance such that when the sensed distance is greater than the preset distance, the control unit is configured to supply power for the sending coil and the sending coil is configured to generate the induced magnetic field, and when the sensed distance is not greater than the preset distance, the control unit is configured to refrain from supplying power for the sending coil and the sending coil is configured to refrain from generating the induced magnetic field.

Abstract
A wireless charging device charging for an electronic device is disclosed. The wireless charging device includes a control unit, a sending coil coupled to the control unit, and a range sensor coupled to the control unit. The sending coil generates an induced magnetic field accepted by the electronic device. The range sensor senses a distance between a user and the wireless charging device, and further configured to determine if the sensed distance is greater than a preset distance. The sensed distance is greater than the preset distance, the control unit supplies power for the sending coil, and the sending coil generates the induced magnetic field. The sensed distance is smaller than a preset distance, the control unit stops to supply power for the sending coil, and the sending coil stops to generate the induced magnetic field.
