Planar induction coil assembly and multi-receiving wireless charging device

The invention provides a planar induction coil assembly. The planar induction coil assembly comprises a first coil, a second coil and a third coil, the first coil has a first spiral direction from outside to inside, the second coil has a second spiral direction, and the first spiral direction is opposite to the second spiral direction. The first coil, the second coil and the third coil are electrically isolated from each other, and the vertical projection of each of the first coil, the second coil and the third coil is partially overlapped with the vertical projection of at least one of the other two coils. The invention further provides a multi-receiving type wireless charging device which comprises a first coil, a second coil and a third coil. The first coil and the second coil have opposite current directions, and the first coil and the third coil have the same current direction. 本发明提供一种平面式感应线圈组件，其包含第一线圈、第二线圈及第三线圈。第一线圈具有由外向内的第一螺旋方向，第二线圈具有第二螺旋方向，第一螺旋方向与第二螺旋方向相反。第一线圈、第二线圈及第三线圈彼此电性隔离，且第一线圈、第二线圈及第三线圈中的每一线圈的垂直投
