Abstract
The present disclosure provides a wireless charging coil, and the wireless charging coil comprises a first coil layer, a second coil layer and a first magnetic material. The second coil layer is stacked in parallel on a surface of the first coil layer to form a stacked structure, and it has a winding path identical to a winding path of the first coil layer. The first magnetic material is disposed on one side of the first coil layer and has a winding path which is different from the winding path of the first coil layer and with said side away from the second coil layer. Currents generated by a power source are evenly distributed in the stack structure to reduce a skin effect when the wireless charging coil is electrically connected to the power source.
Claims9
A wireless charging coil, comprising:
- a first coil layer;
- a second coil layer stacked in parallel on a surface of the first coil layer to form a coil stacked structure, and a width of the first coil layer is greater than a width of the second coil layer;
- a first magnetic material disposed on a surface of the first coil layer and having a width larger than the width of the first coil layer and the width of the second coil layer, with said surface away from the second coil layer;
- and
- a signal guiding member electrically connected to the first coil layer and the second coil layer;
- wherein currents of a power source are evenly distributed to the first coil layer and the second coil layer to reduce a skin effect when the wireless charging coil is electrically connected to the power source through the signal guiding member.
