Abstract

A cover member of an electronic device is provided. The cover member includes covers hingedly connected, wherein each cover includes a power receiving member configured to wirelessly receive power.

Claims

1. A cover member of an electronic device, the cover member comprising:

covers hingedly connected,

wherein each cover includes a power receiving member configured to wirelessly receive power.

2. The cover member of claim 1, further comprising:

a wireless power receiving unit that receives power through at least one of the power receiving members and generates power for charging.

3. The cover member of claim 2, wherein the wireless power receiving unit further comprises wireless power receivers that are respectively connected with the power receiving members, receive power through correspondingly connected power receiving members, and generate the power for charging.

4. The cover member of claim 3, wherein the wireless power receiving unit is included in one of the covers.

5. The cover member of claim 3, wherein each of the wireless power receivers is included in a corresponding cover among the covers.

6. The cover member of claim 3,

wherein the wireless power receivers are connected to a charger that charges a battery, and

wherein the cover member further comprises a switch that turns on or off a path between the charger and one of the wireless power receivers connected to one of the power receiving members included in a front side cover among the covers, to correspond to an open or shut state of the covers.

7. The cover member of claim 6, wherein the switch is turned on when the covers are open and is turned off when the covers are shut.

8. The cover member of claim 3,

wherein the wireless power receivers are connected with a charger that charges a battery, and

wherein the cover member further comprises:

a first switch configured to turn on or off a path between the charger and one of the wireless power recivers connected with one of the power receiving members included in a front side cover among the covers;

a second switch configured to turn on or off a path between the charger and another of the wireless power receivers connected to another of the power receiving members included in a back side cover among the covers; and

a controller configured to control turning on or off of the first switch and the second switch to correspond to an open or shut state of the covers and an overturn state of the electronic device.

9. The cover member of claim 8, wherein the controller is configured to perform:

turning on both the first switch and the second switch when the covers are open;

turning the first switch on and turning the second switch off when the covers are shut and the electronic device is upside down; and

turning the first switch off and turning the second switch on when the covers are shut and the electronic device is not overturned.

10. The cover member of claim 1, wherein a back side cover among the covers is installed in the electronic device as a back side cover of the electronic device.

11. An electronic device comprising:

a charger configured to charge a battery through power for charging generated by at least one of wireless power receivers, the wireless power receivers respectively receiving power through power receiving members respectively included in covers hingedly connected, and generating the power for charging.

12. The electronic device of claim 11, further comprising:

a cover sensor configured to sense an open and shut state of the covers; and

a switch configured to turn on or off a path between the charger and one of the wireless power receivers connected with one of the power receiving members included in a front side cover among the covers, to correspond to the open or shut state of the covers.

13. The electronic device of claim 12, wherein the switch is turned on when the covers are open and is turned off when the covers are shut.

14. The electronic device of claim 11, further comprising:

a first switch configured to turn on or off a path between the charger and one of the wireless power receivers connected with one of the power receiving members included in a front side cover among the covers;

a second switch configured to turn on or off a path between the charger and another of the wireless power receivers connected with another of the power receiving member included in a back side cover among the covers;

a cover sensor configured to sense an open and shut state of the covers;

a pose sensor configured to sense whether the electronic device is upside down; and

a controller configured to control turning on or off of the first switch and the second switch to correspond to the open or shut state of the covers and an overturn state of the electronic device.

15. The electronic device of claim 14, wherein the controller is configured to perform:

turning on both the first switch and the second switch when the covers are open;

turning the first switch on and turning the second switch off when the covers are shut and the electronic device is upside down; and

turning the first switch off and turning the second switch on when the covers are shut and the electronic device is not overturned.

16. A wireless charging method of an electronic device, the wireless charging method comprising:

generating power for charging from power wirelessly received through at least one of power receiving members respectively included in hingedly connected covers ; and

charging a battery with the power for charging.

17. The wireless charging method of claim 16, wherein the generating of the power for charging further comprises:

sensing an open or shut state of the covers; and

generating the power for charging using at least one power receiving member corresponding to the open or shut state of the cover from among the power receiving members.

18. The wireless charging method of claim 17, wherein the generating of the power for charging using the at least one power receiving member further comprises:

generating the power for charging from power wirelessly received through the one of the power receiving members included in a front side cover among the cover and the other of the power receiving members included in a back side cover among the covers when the covers are open; and

generating the power for charging from power wirelessly received through a power receiving member included in the back side cover when the covers are shut.

19. The wireless charging method of claim 16, wherein the generating of the power for charging further comprises:

sensing an open or shut state of the covers;

sensing whether the electronic device is upside down; and

generating power for charging using at least one power receiving member corresponding to the open or shut state of the covers and an overturn state of the electronic device from among the power receiving members.

20. The wireless charging method of claim 19, wherein the generating of the power for charging using the at least one power receiving member further comprises:

generating the power for charging using all of the power receiving members when the covers are open;

generating power for charging using one of the power receiving members included in one of the covers used as a front side cover when the covers are shut and the electronic device is upside down; and

generating power for charging using another of the power receiving members included in another of the covers used as a back side cover when the covers are shut and the electronic device is not overturned.
