Description
Technical field
The present invention relates to a kind of structures of no FPC antenna, in particular to a kind of to be based on mobile device three-stage metal-back material
NFC structure.
Background technique
NFC be it is a kind of provide easily, safety, the wireless connection technology that rapidly communicates, NFC have distance is close, bandwidth is high,
The features such as low energy consumption.Secondly, NFC is compatible with existing contactless smart card technology, have become to obtain at present more and more main
The official standard that manufacturer supports.Again, NFC or a kind of short-range connection protocol, it is light, safe, fast to provide various equipment rooms
Speed and automatically communicate.Compared with other connection types in wireless world, NFC is a kind of secret communication mode of short distance.
NFC plays huge effect in the fields such as gate inhibition, public transport, mobile device for paying.Most of NFC mobile device is built-in
NFC chip, additional NFC antenna, as mobile device inner space is smaller and smaller, few spaces for providing additional NFC antenna,
Conventional NFC antenna has been difficult to the requirement of mobile device thickness on thickness, and current Mobile equipment shell is generally three sections
Formula metal-back material, the i.e. interlude of shell are metal material, and upper-lower section is plastic cement material, it is therefore necessary to be proposed a kind of based on shifting
The NFC structure of dynamic equipment three-stage metal-back material is current to solve the problems, such as, NFC performance is radiated using mobile device mainboard,
FPC antenna is not needed, so cost can be saved and meet complete machine thickness requirements.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of achievable NFC function
Can, be not necessarily to attachment NFC antenna, save cost, meanwhile, save mobile device space based on mobile device three-stage metal-back material
NFC structure.
The purpose of the present invention can be achieved through the following technical solutions: one kind being based on mobile device three-stage metal-back material
NFC structure, which is characterized in that metal segments (3) including Mobile equipment shell middle section, and being connect with metal segments (3)
Metal strip (1), which is arranged in the plastic cement section (2) of Mobile equipment shell, the metal segments (3) and metal strip
(1) NFC function is realized.
Described metal strip (1) the elongated shape, the elongated metal item (1) is parallel with the metal segments (3) boundary, and
Elongated metal item (1) one end is connected on metal segments (3), and the other end is feed point (a1).
Elongated metal item (1) one end bending is connected to metal segments (3).Another feed point, shape are formed in metal segments
At a cyclic structure, NFC antenna is served as.
The metal segments (3) and metal strip (1) integrated design, are directly generating on three-stage shell of mobile device material.
Metal strip is a part that metal segments extend to plastic cement section, and the metal strip under plastic cement section is longer, and wider, NFC effect is better.
Metal strip (1) landfill is in plastic cement section (2).
The metal strip (1) is plated in plastic cement section (2) surface.
The length of the metal strip (1) is most greatly enhanced in 30mm or more, and according to the of different sizes of the shell of mobile device
It spends equal with the width of mobile device.
The width of the metal strip (1) is in 2mm or more.The bigger NFC of metal strip and metal segments gap under plastic cement section is imitated
Fruit is better, and maximum width is less than the width of plastic cement section, the gap between the elongated metal item (1) and the metal segments (3)
In 2mm or more.Therefore, according to the size and structure of product, to adjust metal strip width and its between metal segments between
Gap realizes optimal collocation.
Metal strip and metal segments gap under the plastic cement section can increase ferrite.
At least one section is plastic cement material in the mobile device three-stage metal-back material.
Compared with prior art, the present invention dexterously utilizes mobile device mainboard, the especially shifting of three-stage metal-back material
Dynamic equipment, using the metal segments part in its metal-back material as a part of antenna, and in the setting of plastic cement section part and metal segments
The metal strip of connection forms a cyclic structure, serves as NFC antenna, carries out electromagnetism using the loop that PCB trace on mainboard is formed
The features such as radiation has structure simple, at low cost, superior performance.NFC performance is radiated using mobile device mainboard, is not needed
FPC antenna, so cost can be saved and meet complete machine thickness requirements.
Using a kind of NFC structure based on metal-back material without antenna invented above, applies on non-metal case material, have
The features such as structure is simple, good appearance, superior performance.

Fig. 2 is the shell of mobile device material NFC appearance diagram that the present invention is implemented；
Fig. 3 is the shell of mobile device material NFC overall schematic that the present invention is implemented.
Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.Below with reference to attached drawing, to the present invention
Specific embodiment be described in detail.Then, the present invention can in different forms, specification etc. realize, in these attached drawings, be
It is clearly visible, it may increase or reduce, relative size can also be zoomed in or out.
The most critical design of the present invention is: being made with the becket that the metal strip and metal segments of metal-back material plastics section are formed
For NFC radial coil, NFC function is realized without additional FPC antenna to realize.
Embodiment 1
As shown in Figure 1-3, a kind of NFC structure based on mobile device three-stage metal-back material, wherein the three-stage
Shell material refers to that upper-lower section is the shell material that plastic cement interlude is metal, if Fig. 1 shows, is the design of intermetallic metal section, is based on this shell material
