Magnetic self-aligning coil centering for wireless charging
First Claim
1. A charging device, comprising:
- a first induction coil configured to transmit power wirelessly to a portable device having a second induction coil;
a first charging surface including a first coil charging area defined by the first induction coil;
a first magnet having a first pole and a second pole and disposed at the first charging surface; and
a second magnet having a first pole and a second pole and disposed at the first charging surface, whereinwhen the portable device is in proximity of the charging device, the first pole of the first magnet creates a first magnetic attraction force with a third magnet disposed at a second charging surface of the portable device, and the second pole of the second magnet creates a first magnetic repulsion force with the third magnet, whereinwhen the second charging surface of the portable device is placed adjacent to the first charging surface of the charging device, the first magnetic attraction force and the first magnetic repulsion force cause the first coil charging area and a second coil charging area of the second charging surface to be aligned, and wherein the second coil charging area defined by the second induction coil,wherein the first magnetic attraction force provides an anti-tip magnetic attraction force when the portable device is adjacent to the first charging surface and a touch force is applied to a display portion of the portable device when the display portion is in an open position.

Abstract
Systems and methods for magnetic self-aligning coil centering for wireless charging may include a charging device that may transmit power wirelessly to a portable device. The charging device may include a first magnet and a second magnet. When the portable device may be in proximity of the charging device, a first pole of the first magnet may create a first magnetic attraction force with a third magnet of the portable device, and the second pole of the second magnet may create a first magnetic repulsion force with the third magnet. When the portable device is placed adjacent to the charging device, the first magnetic attraction force and the first magnetic repulsion force may cause a first coil charging area of the charging device and a second coil charging area of the portable device to be aligned.
