Further, the coil with more leads uses multiply silk-covered wire coiled wire-wound coil scheme.
Further, the coil with more leads can be circular configuration design, square structure design, six sidesThe design of shape structure and eight-sided formation design, it is preferred that designed for circular configuration.
Further, the coil line with more leads is slightly 0.5 ~ 1.5mm, it is preferred that line is slightly 0.8 ~1.2mm。
Further, the magnetic material that the antifreeze plate for enhancing wireless charging efficiency is 0.2 ~ 3mm of thickness, preferably, with a thickness of 0.5 ~ 2mm；Antifreeze plate material is sintering manganese-zinc ferrite, sintering nickel-zinc ferrite, nanometer crystal alloy, amorphous conjunctionThe composite material of one or more of gold etc..
Further, the antifreeze plate for enhancing wireless charging efficiency can be completely covered described with more leadsCoil area.
Further, it is described control wireless charging frequency control IC by using connection two it is different described in have it is moreThe lead of the coil of root lead, the wireless charging frequency to adjust different determine connection side when output power reaches maximum valueCase simultaneously carries out wireless charging to equipment.
Compared with prior art, the beneficial effects of the present invention are:
The present invention provides a kind of adjustable frequency wireless charging transmitting terminal mould groups, by the control IC of wireless charging frequency come basisCharging equipment is matched and the different leads of the coil with more leads is selected to adjust charge frequency, to distinct device intoRow electromagnetic coupling is powered, and solves the problems, such as that distinct device is inconsistent to wireless charging frequency requirement, greatly improves consumptionPerson manages troublesome idea and reality to wireless charging device, further reduced use of the consumer to wireless charging transmitting terminalCost.
