To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme：
A kind of multi-frequency for wireless charging emits end-coil module, including a TX wireless transmission end housing, the TX without
It is superimposed with two layers of coil array layer in line transmitting end housing；Wherein, be provided on the coil array layer of bottom several
One coil and the second coil, the first coil and second coil are discharged using interleaved mode, and the two is not blocked mutually, to subtract
Interference between few two frequencies；Several tertiary coils, the first coil, institute are provided on the coil array layer of top layer
It states the second coil and the tertiary coil and corresponds to three kinds of different optimal wireless charging frequencies respectively.
Further, the first coil, second coil and the tertiary coil are all made of cell array design, with
Meet multiple positions freely to charge.
Further, the optimal wireless charging frequency of the first coil is higher than the optimal wireless charging of second coil
Frequency, the optimal wireless charging frequency of second coil are higher than the optimal wireless charging frequency of the tertiary coil.
