Technical field
The utility model relates to wireless charging device, is specifically related to the transmitting coil structure of wireless charging.
Background technology
Wireless charger refers to the equipment that utilizes electromagnetic induction principle to charge, in wireless charger, be provided with transmitting coil, and the equipment that is recharged is provided with receiving coil, by the current excitation generation alternating magnetic field of transmitting coil, and then excitation receiving coil generation current, to being recharged equipment, charge.Traditional wireless charger loop construction as shown in Figure 1, by wire disk, being coiled into coil 3 ' is arranged on magnetic sheet 1 ', the two ends of coil 3 ' are for lead-in wire is for being connected with the electric device that produces exciting current, the lead-in wire 32 ' that is wherein positioned at coil 3 ' outer end can directly stretch out, and is positioned at same plane with the main part of coil 3 '; Being positioned at coil 3 ' inner lead-in wire 31 ' needs the top that strides across coil 3 ' outwards to draw again.Such structure makes wireless charger in use, will inevitably increase the spacing between receiving coil and transmitting coil, reduces and connects sensitivity and charge efficiency.In existing product, for dwindling the spacing of receiving coil and transmitting coil, the scheme conventionally adopting is shell to be subtracted to glue process, and to reduce the thickness of shell, but subtract glue processing meeting, the intensity of shell is impacted, and easily damages product.
Utility model content
Not enough for above-mentioned prior art, the technical problems to be solved in the utility model is to provide a kind of wireless charger that is different from prior art and sends loop construction, effectively reduces the distance of receiving coil and transmitting coil, improves and connects sensitivity and charge efficiency.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is, wireless charger loop construction, the coil that comprises magnetic sheet and be located at magnetic sheet top, it is characterized in that: the upper surface of described magnetic sheet is provided with hole groove, the inner lead-in wire of coil is placed in the groove of described hole, and the end of inner lead-in wire stretches out in magnetic sheet outside.
Preferably, one end of described hole groove is communicated with the side of magnetic sheet, and other end end is positioned at the middle part of magnetic sheet.
Another kind of technical scheme of the present utility model is between described magnetic sheet and coil, to be also provided with pad; Described pad is provided with breach, and the inner lead-in wire of coil is placed in described breach and the end of inner lead-in wire stretches out in pad outside.
Preferably, one end of described breach is positioned at the edge of pad, and the other end is positioned at the middle part of pad.
Another kind of technical scheme of the present utility model is, the middle part of described magnetic sheet is provided with through hole, and the lower surface of magnetic sheet is provided with hole groove, and this hole groove is communicated with described through hole; The inner lead-in wire of coil is placed in the groove of described hole through this through hole, and the end of inner lead-in wire stretches out in magnetic sheet outside.
Wireless charger loop construction of the present utility model, can effectively the inner of transmitting coil lead-in wire be drawn from the below of coil, dwindle the spacing of wireless charger top cover and coil, and then dwindle the distance of transmitting coil and receiving coil, improve and connect sensitivity and charge efficiency.
