Abstract

A wireless charging system may provide charging to a portable device. A docking station in the system may include a first transmission source configured to emit wireless charging power along a first transmission axis from a first body. The docking station may include a second power transmission source configured to emit wireless charging power along a second transmission axis from a second body. In some embodiments, the first transmission axis may not intersect with the second transmission axis. In some embodiments, the first transmission axis may be divergent from the second transmission axis.

Claims

1. A docking station for charging a portable device, comprising:

a first body;

a first transmission source configured to emit wireless charging power along a first transmission axis from the first body;

a second body rotatable with respect to the first body; and

a second power transmission source configured to emit wireless charging power along a second transmission axis from the second body, wherein the first transmission axis does not intersect with the second transmission axis.

2. The docking station of claim 1, wherein the first power transmission source and the second power transmission source are inductive coils.

3. The docking station of claim 1, wherein the hinge is a multi-axis hinge.

4. The docking station of claim 1, wherein a direction of transmission for the second power transmission source is uni-directional along the second transmission axis.

5. The docking station of claim 1, further comprising a ledge on the first body or the second body configured to support the portable device.

6. The docking station of claim 5, wherein the ledge is spring loaded and configured to move from a first position to a second position.

7. A docking station for charging a portable device, comprising:

a first transmission source disposed to emit wireless power in a first direction and a second transmission source disposed to emit wireless power in a second direction,

wherein, when the docking station is in;

a first mode, the first direction is substantially parallel to the second direction, and

a second mode, first direction is divergent from the second direction.

8. The docking station of claim 7, further comprising a hinge connecting a first body of the docking surface to a second body of the docking surface.

9. The docking station of claim 8, wherein the hinge is a multi-axis hinge.

10. The docking station of claim 9, wherein the docking surface is configured to provide emission of wireless power in a third mode that includes the first direction being opposite to the second direction.

11. The docking station of claim 7, further comprising a ledge on the docking surface configured to support the portable device in the second mode.

12. The docking station of claim 11, wherein the ledge is angled from a support surface.

13. The docking station of claim 12, wherein the ledge is spring loaded and configured to move from a first position to a second position.

14. The docking station of claim 7, wherein the docking surface is foldable.

15. A wireless charging system, comprising:

a portable device; and

a foldable docking station configured to receive the portable device for charging, including;

a first transmission source configured to emit wireless charging power along a first transmission axis; and

a second power transmission source configured to emit wireless charging power along a second transmission axis, wherein the first transmission axis is divergent from the second transmission axis.

16. The system of claim 15, wherein the first device segment is pivotally attached to the second device segment.

17. The system of claim 15, further comprising a hinge connecting a first body of the docking surface to a second body of the docking surface.

18. The system of claim 17, wherein the foldable docking station is configured to support the portable device along a ridge of the foldable docking station.

19. The system of claim 18, wherein the ridge includes the hinge.

20. The system of claim 15, wherein the first transmission axis does not intersect with the second transmission axis.
