At least a portion of structure.Specifically, in present embodiment, one end of the second shaft 216b passes through the second metal wire 211b
The ground 211c of the Part I is connected, the other end of the second shaft 216b passes through the 3rd metal wire 212a connections second
Point ground 212c, therefore, the first metal wire 211a, first rotating shaft 216a, the 4th metal wire 214a, the second shaft 216b,
The second metal wire 211b and the 3rd metal wire 212a form at least a portion of antenna structure.
Further, the first metal of the 3rd metal wire 214a of the flexible PCB 214 and the Part I 211
It can also be electrically connected between line 211a by connecting element 270, the connecting element 270 and the connection in first embodiment
As element 170, it can be electroconductive elastic sheet, conducting foam, pogo pin or connector, not only ensure the flexible PCB
Connection reliability between 240 and first and second described part 211,212, and cost is not high, it is easy to implement.
In the second embodiment, the flexible PCB 214 can include the 4th metal wire 214a, the 4th gold medal
The both ends of category line 214a are with being electrically connected the first metal wire 211a of the Part I 211 so that first metal wire
211a, first rotating shaft 216a, the 4th metal wire 214b, the second shaft 216b form at least a portion of antenna structure, user
Can be according to the antenna structure for being actually needed first and second above-mentioned which kind of embodiment of selection.
It is used for it is appreciated that near field antenna includes NFC, wireless charging etc. under the closely scene such as Card Reader communication or charging
Coupled antenna, common near field antenna solution have three classes：
1st, near field antenna is positioned over rear cover plastic cement or glass windowed regions.Antenna headroom environment is good, beneficial to aerial radiation, and
Other antennas are not influenced, but influence cell phone appearance and feel；
2nd, in ring camera one week, antenna was placed in metal back cover inner surface, the becket side of camera near field antenna design
Somewhere is cut off, but slotting influences product aesthetics.
3rd, the upper and lower metal strip of rear cover is utilized.With GPS/WIFI antennas and the major and minor antenna duplexers of LTE.This scheme may be right
GPS/WIFI antennas and the major and minor aerial band of LTE influence, and near field antenna radiator is shorter, read-write card poor-performing.
In conclusion the invention has the advantages that：
1st, using the shaft and flexible PCB at flexible electronic devices shaft, near field antenna function is realized；
2nd, near field antenna performance is good, and from the influence of flexible electronic devices state change；
3rd, extra ferrite part need not be increased, it is of low cost.
The above disclosed right for being only better embodiment of the present invention, the present invention cannot being limited with this certainly
Scope, therefore equivalent variations made according to the claims of the present invention, are still within the scope of the present invention.
