Wireless charging base and operation method thereof

Abstract

A wireless charging dock includes a base, a controller, a drive assembly, a central track, multiple peripheral tracks, a wireless coil, and multiple sensors. The base includes a central region. The controller is disposed within the base. The drive assembly is disposed within the base and electrically connected to the controller. The central track is disposed within the base and linked to the drive assembly, rotatably positioned within the central region of the base. The peripheral tracks are disposed within the base and radially arranged around the periphery of the central region; the central track is driven by the drive assembly to engage with one of the peripheral tracks. The wireless coil is disposed within the base, electrically connected to the controller, and linked to the drive assembly, moving along either the central track or one of the peripheral tracks. The sensors are evenly spaced on the base and electrically connected to the controller.

Claims

1. A wireless charging dock, comprising: A single entity, including a central area; A controller is disposed within the base; a drive assembly is disposed within the base and electrically connected to the controller; a central track is disposed within the base and connected to the drive assembly, rotatably disposed within the central region of the base; a plurality of peripheral tracks are disposed within the base and radially disposed around the periphery of the central region, the central track being driven by the drive assembly to engage with one of the peripheral tracks; a wireless coil is disposed within the base, electrically connected to the controller and connected to the drive assembly, for movement along either the central track or one of the peripheral tracks; and a plurality of sensors are equally spaced disposed on the base and electrically connected to the controller.

2. The wireless charging stand as claimed in claim 1, wherein the stand body is rectangular and the peripheral tracks extend toward the four corners and the four midpoints of the four sides of the rectangle.

3. The wireless charging dock as claimed in claim 2, wherein each of the sensors is a light sensor, and the sensors are disposed on the four sides or four corners of the rectangle.

4. The wireless charging dock as claimed in claim 1, wherein the driving assembly includes a first motor and a gear set, the gear set being driven by the first motor, the central track being driven by the gear set, and the central track rotating through the gear set.

5. The wireless charging dock as claimed in claim 1, wherein the drive assembly includes a second motor coupled to the wireless coil to drive the wireless coil to move along one of the central track or the peripheral tracks.

6. A method of operating a wireless charging dock, suitable for supplying power to an electronic device, comprising: A wireless charging dock is provided, including a body, a plurality of sensors located on the body, and a wireless coil movably disposed within the body. The body includes a central region and a plurality of peripheral regions located outside the central region. When an electronic device is placed on the body of the wireless charging dock, at least one of the sensors detects that it is blocked, wherein the at least one of the sensors that detects that it is blocked corresponds to at least one of the peripheral regions. The wireless coil is positioned in the central region, and a charging test is performed on the electronic device to confirm whether the output wattage of the wireless coil exceeds a preset value. If the output wattage does not exceed the preset value when the wireless coil is in the central region, the wireless coil begins charging the electronic device in the central region. If the output wattage exceeds the preset value when the wireless coil is located in the central area, the wireless coil is moved to at least one of the peripheral areas to perform a charging test on the electronic device, in order to determine which of the at least one peripheral area the wireless coil is located in when the output wattage of the wireless coil does not exceed the preset value; and in the peripheral area where the output wattage of the wireless coil does not exceed the preset value, the wireless coil charges the electronic device.

7. The method of operating the wireless charging dock as described in claim 6, wherein the preset value is between the rated output wattage of the wireless coil and 0.35 to 0.5 watts.

8. The method of operating a wireless charging dock as claimed in claim 6, wherein in the step of determining which of the at least one of the peripheral areas the output wattage of the wireless coil does not exceed the preset value, the search is stopped once it is found that the output wattage of the wireless coil in one of the peripheral areas does not exceed the preset value.

9. A method of operating a wireless charging dock as described in claim 6, wherein the wireless charging dock comprises: A drive assembly is disposed within the base body; a central track is disposed within the base body and connected to the drive assembly, and is rotatably disposed within the central region of the base body; and a plurality of peripheral tracks are disposed within the base body and radially disposed around the periphery of the central region, the central track being driven by the drive assembly to engage with one of the peripheral tracks, and the wireless coil being connected to the drive assembly to move along either the central track or one of the peripheral tracks.

10. The method of operating a wireless charging pad as claimed in claim 9, wherein the number of the peripheral areas corresponds to the number of the peripheral tracks.
