Embodiment 1
[0023] Such as figure 1 The shown wireless charging coil includes an excitation layer 5, and a first coil loop loop 1, a second coil loop loop 2, a third coil loop loop 3, and a fourth coil loop loop wound by the same insulated wire. 4. In order to describe the positional relationship of the four coil loops, in figure 1 The coordinate system is drawn with the vertical line of the excitation layer as the y-axis and the horizontal direction along the excitation layer as the x-axis.
[0024] Such as figure 1 As shown, the four coil loops are respectively located in four quadrants, and the winding shapes are all rectangular. Wherein, the first coil loop 1 and the third coil loop 3 are adjacently arranged on the upper end surface of the excitation layer 5 , and the planes of the first coil loop 1 and the third coil loop 3 are parallel to the excitation layer 5 .
[0025] The second coil loop loop 2 is adjacent to the fourth coil loop loop loop 4, and is arranged around the uppe...
Embodiment 2
[0034] The wireless charging coil of this embodiment is as Figure 5 , Image 6 As shown, it includes an excitation layer 5 and a coil loop loop wound by the same insulated wire. The coil loop loop includes a first coil loop loop 1 and a second coil loop loop 2, wherein the first coil loop loop 1 is arranged in the excitation On the upper end face of the layer, the plane where the first coil loop loop 1 is located is parallel to the excitation layer 5 .
[0035] The second coil loop 2 surrounds the upper and lower end surfaces and two side surfaces of the excitation layer 5; The current direction of -1 is consistent, and the side 2-1 of the second coil loop on the upper end surface of the excitation layer is set close to the side 1-1 of the first coil loop. The upper end surface of the excitation layer 5 is provided with a groove, and when the number of coil turns of the second coil loop 2 is multiple turns, the insulated wire of the second coil loop 2 is placed in the groov...
