Wireless charger reflector coil winding arrangement described in the utility model, its special electricity is to comprise on PCB wiring board, PCB wiring board end face and the bottom surface ferrite magnetic sheet that arranges on the bottom surface of the coil windings that arranges respectively and PCB wiring board bottom surface coil windings, is provided with the Copper Foil coil windings in the wherein said PCB wiring board.
Can effectively charge in order to make wireless charger described in the utility model and to be subjected to need not between the charging device accurate positioning instant, and can realize that multiple devices charge simultaneously, the Copper Foil coil windings that arranges on each coil of above-mentioned each coil windings and the PCB wiring board forms respectively the stereo structure structure that has double-layer structure at least and arrange by " product " font from the bottom up.
In order to make easy for installation, the compact conformation, reliable of coil windings, the end face of above-mentioned PCB wiring board and bottom surface are respectively arranged with the circular location notch for each coil that loads coil windings.
For the ease of producing and assembling, above-mentioned ferrite magnetic sheet is comprised of 2 or 2 the square magnetic sheet of times several piece.
The utility model also forms the coil sections Winding Design in the PCB wiring board owing to adopting with the Copper Foil coiling, the coil windings that arranges on end face and the bottom surface simultaneously directly is close on the PCB wiring board, this design can effectively reduce the height of structural member, it is compacter that coil windings is arranged, energy conversion efficiency is higher, the electrical parameter consistency of product is better, can also arbitrarily increase and decrease the quantity of the size of PCB wiring board and coil windings to reach designing requirement according to the practical application needs.In addition, because coil windings is arranged to be divided into stereo structure structure two-layer at least and that rearrange by " product " font from the bottom up by a plurality of coils, make wireless charger and be subjected to need not between the charging device accurate positioning instant and can effectively charge, and can realize that multiple devices charge simultaneously, both improved charge efficiency, increased again the scope of application of wireless charger, can cover 90% above power on the market and use in the charging of the portable type mobile device below 5 watts, and the utility model novel structure, reasonable in design, safe and reliable.
Below in conjunction with accompanying drawing the utility model is further described.
