Referring to Fig. 6, the flexible electronic devices 30 that Fig. 6 is third embodiment of the invention are gone when being in tiling unfolded state
Except the structure schematic diagram after shell.The flexible electronic devices 30 of 3rd embodiment and the flexibility of first embodiment
The structure of electronic equipment 10 is essentially identical, the two main difference is that：The other end of first metal wire 311a is electrically connected first
One end of shaft 316a, the other ends of the first rotating shaft 316a away from the first metal wire 311a pass through the 3rd metal wire
312a is electrically connected one end of the second metal wire 314a, the other end ground connection of the second metal wire 314a.Specifically, described second
The other end of metal wire 314a can be grounded in several ways, be such as directly grounded or by other connecting elements or metal wire
It is connected to the ground 311c of the Part I, in present embodiment, the other end of the second metal wire 314a passes through described
Four metal wire 311b are electrically connected to the ground 311c of the Part I.
In 3rd embodiment, the first metal wire 311a, the first rotating shaft 316a, the 3rd metal wire
At least a portion of 312a and the second metal wire 314a composition antenna structures, but the antenna in the 3rd embodiment
It is slightly different in the circuit of structure and first embodiment.
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.
