Specific implementation mode
A kind of wireless charging applied to anury on-site law-enforcing recorder of-Fig. 3 referring to Fig.1, the utility model receive dress
It sets, including battery accommodating case 1, at the back of battery accommodating case 1, there are one rectangular coil mounting groove 11, coil mounting grooves for setting
11 for placing NFC high frequency antennas 2 and wireless charging receiving coil 3, due to the design of existing wireless charging receiving coil 3
All it is conventional square spiral either round screw thread structure, this conventional structure can not simultaneously be applicable in NFC high frequency antennas 2
In the structure of on-site law-enforcing recorder；And in order to improve space availability ratio, generally require by wireless charging receiving coil 3 with
NFC high frequency antennas 2 are nested, are superimposed or wireless charging receiving coil 3 is placed in inside NFC high frequency antennas 2, but above-mentioned installation
Mode can all increase integral thickness, reduce space availability ratio, and the utility model connects by NFC high frequency antennas 2 and wireless charging
Take-up circle 3 is designed at battery 1 back of accommodating case, is changed to the structure of wireless charging receiving coil 3, in traditional ring
On the basis of shape wireless charging receiving coil 3, wireless charging receiving coil 3 is designed as the spelling with arc portion and straight line portion 32
Connect formula design, wherein wireless charging receiving coil 3, which corresponds at 11 one of angle of coil mounting groove, is designed as the first arc portion
31, the first arc portion 31 is the design being recessed inwardly to 11 central point of coil mounting groove, so, in the outside of the first arc portion 31
It is left with a larger region, which can be used to place NFC high frequency antennas 2, to realize 2 He of NFC high frequency antennas
Wireless charging receiving coil 3 is placed in conplane effect, and such structure design is suitable for on-site law-enforcing recorder, pole
Big improves space availability ratio.
For the position of NFC high frequency antennas 2 and wireless charging receiving coil 3 is put, tiling is best design,
Since NFC high frequency antennas 2 are rectangular, and wireless charging receiving coil 3 is spiral, so a nested and shared structure
Both of which can not achieve；If being positioned over the structure inside wireless charging receiving coil 3 using NFC high frequency antennas 2,
It is inherently superimposed upon on wireless charging receiving coil 3 when the feeder line of NFC high frequency antennas 2 extracts, to increase integral thickness；It is aobvious
So directly superposition also has the drawbacks of increasing thickness；If directly not using the utility model to design using the structure of tiling
Unfilled corner loop construction, then space availability ratio just becomes lowly, so the utility model is for wireless charging receiving coil 3
The design of one arc portion 31 can improve space availability ratio.
