Abstract

A charging device for charging one or more electronic devices is provided. The charging device includes a charging unit configured to include a first charging unit, and a second charging unit, the second charging unit protruding upward from a surface of the charging unit at an angle greater than or equal to a predetermined reference angle with respect to the surface of the charging unit, wherein, if at least one of the first charging unit and the second charging unit is arranged to face at least one electronic device in a face-to-face manner, the at least one of the first charging unit and the second charging unit supplies wireless power to the at least one electronic device.

Claims

1. A charging device for charging one or more electronic devices, the charging device comprising:

a charging unit configured to include a first charging unit and a second charging unit, the second charging unit protruding upward from a surface of the charging unit at an angle greater than or equal to a predetermined reference angle with respect to the surface of the charging unit,

wherein the second charging unit is configured to include a groove into which at least one electronic device is to be inserted so that the at least one electronic device is arranged to face the second charging unit in a face-to-face manner.

2. The charging device of claim 1, wherein, if the charging unit is implemented as a rectangular parallelepiped, the second charging unit is included in any one of a top left corner, a bottom left corner, a top right corner and a bottom right corner of the charging unit.

3. The charging device of claim 1, wherein a charging surface of the first charging unit is positioned parallel to the ground, and, if an angle between the at least one electronic device and the surface of the charging unit is the predetermined reference angle, the second charging unit supplies wireless power to the at least one electronic device.

4. The charging device of claim 1, wherein, if each of the first charging unit and the second charging unit is arranged to face the at least one electronic device in the face-to-face manner, each of the first charging unit and the second charging unit supplies wireless power to the at least one electronic device.

5. A processor-implemented method for receiving wireless power at an electronic device, the processor-implemented method comprising:

determining whether the electronic device starts to receive the wireless power from a charging device; and

running a clock mode in the electronic device based on determining that the electronic device starts to receive the wireless power from the charging device; and

stopping running the clock mode based on determining that the electronic device is not able to receive the wireless power from the charging device.

6. The processor-implemented method of claim 5, wherein the clock mode is an operation mode for continuously displaying at least one of a date, a day, a current time, and weather.

7. The processor-implemented method of claim 5, further comprising:

determining whether charging is completed; and

maintaining the clock mode, even if the charging is completed.

8. The processor-implemented method of claim 5, further comprising:

determining whether a charging of the electronic device is completed;

determining whether the electronic device is able to receive the wireless power from the charging device; and

if the charging of the electronic device is completed and the electronic device is able to receive the wireless power from the charging device, maintaining the clock mode.

9. An electronic device for receiving wireless power, the electronic device comprising:

a processor configured to;

determine whether the electronic device starts to receive the wireless power from a charging device,

run a clock mode in the electronic device based on determining that the electronic device starts to receive the wireless power from the charging device, and

stop running the clock mode based on determining that the electronic device is not able to receive the wireless power from the charging device; and

a display configured to display at least one of a date, a day, a current time, and weather in the clock mode.

10. The electronic device of claim 9, wherein the clock mode is an operation mode for continuously displaying at least one of the date, the day, the current time, and weather.

11. The electronic device of claim 9, wherein the processor determines whether charging is completed, and maintains the clock mode, even if the charging is completed.

12. The electronic device of claim 9, wherein the processor is further configured to:

determine whether a charging of the electronic device is completed;

determine whether the electronic device is able to receive the wireless power from the charging device, and

if the charging of the electronic device is completed and the electronic device is able to receive the wires power from the charging device, maintain the clock mode.
