Description
Technical field
The utility model relates to the communications field, particularly a kind of electronic installation that is provided with RFID antenna.
Background technology
Development along with technology, RFID (Radio Frequency Identification, radio-frequency (RF) identification) the The Application of Technology scope is increasingly extensive, the RFID technology is one and utilizes radiofrequency signal to realize that by space coupling (alternating magnetic field or electromagnetic field) contactless information transmission and the information of passing through to be transmitted reach the technology of identifying purpose, for example, mobile phone is by adopting the RFID technology, can use subscriber identification module (as, SIM card) to consume on the POS machine.
The radio-frequency recognition system that is arranged on electronic installation inside generally is made up of following three parts:
Read write line is used for subscriber identification module is carried out data read-write operation.
Radio-frequency card is a kind of information carrier form with wireless mode transmission data, has distinctive advantages such as data processing and safety certification.
RFID antenna (Antenna) is used to produce magnetic flux, by magnetic flux transmission information between read write line and radio-frequency card.
For the radio-frequency recognition system on being integrated in electronic installation, RFID antenna must be set on electronic installation.Under the traditional approach, in order to increase the magnetic flux by antenna, thereby improve the data delivery quality, the cabling area of RFID antenna can design greatly as far as possible.For example, consult shown in Figure 1, with the mobile phone is example, RFID antenna is arranged on the cell phone rear cover usually, it is maximum that the cabling area of each turn coil all reaches as far as possible, behind the cell phone rear cover that closes, RFID antenna is connected with other functional modules of radio-frequency recognition system by the contact, thereby finishes the transmission of data.
Yet under the prior art, for portable electronic installation, often owing to reasons such as structure and moulding have caused the design section of RFID antenna limited, at this time traditional RFID antenna cabling mode is no longer suitable; And RFID antenna often is arranged on the dismountable bonnet of electronic installation, and the contact performance of influencing contactor is understood in the dismounting repeatedly of bonnet, thereby influences the overall performance of radio-frequency recognition system.
In view of this, need a kind of RFID antenna that is applied to electronic installation of redesign, to overcome above-mentioned defective.
The utility model content
The utility model provides a kind of electronic installation that is provided with RFID antenna, in order to the cabling mode that RFID antenna is set rational in infrastructure in conjunction with electronic installation, guarantees the performance of radio-frequency recognition system in the electronic installation.
The concrete technical scheme that the utility model provides is as follows:
A kind of electronic installation that is provided with RFID antenna, described RFID antenna are arranged in the described electronic installation on the non-removable middle junction member, and the coil of described RFID antenna irregular cabling on described middle junction member.
Among the utility model embodiment, redesigned the RFID antenna in the electronic installation, make RFID antenna be arranged in the electronic installation on the non-removable middle junction member, and the coil of described RFID antenna irregular cabling on described middle junction member.Like this, just be not limited to cabling mode traditionally, efficiently utilized limited design space, improved the design flexibility of RFID antenna, and, based on the stability of middle junction member, also guaranteed the service behaviour of RFID antenna.
Description of drawings
Fig. 1 is for RFID antenna cabling mode under the utility model prior art and the position schematic diagram is set;
Fig. 2 is provided with the position schematic diagram for RFID antenna among the utility model embodiment;
Fig. 3 is a RFID antenna cabling mode schematic diagram among the utility model embodiment;
Fig. 4 is a RFID antenna contact position schematic diagram among the utility model embodiment.
Embodiment
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme:
In the practical application, electronic installation can be mobile phone, PDA, PC, notebook computer or the like, consult Fig. 2 and shown in Figure 3, in the present embodiment, with the mobile phone is example, preferable, RFID antenna is arranged in the mobile phone on the non-removable middle junction member, and the coil of RFID antenna irregular cabling on the middle junction member; Wherein, the placement position of RFID antenna on the middle junction member can for example, can be placed on the top of battery compartment according to the actual application environment flexible design, also can be placed on the below of battery compartment.
So-called middle junction member, promptly be meant in the mobile phone non-removable, as the hardware components of mobile phone agent structure.RFID antenna is arranged on the middle junction member, be in order to improve its stability, the harmful effect of having avoided the dismounting repeatedly of cell phone rear cover to bring for the service behaviour of RFID antenna, and the harmful effect of having avoided the metallicity of cell phone rear cover that the service behaviour of RFID antenna is brought.And with coil irregular cabling on the middle junction member of RFID antenna, be in order in limited design space, to realize the cabling design of RFID antenna, to have improved the design flexibility of RFID antenna.
Further, with the coil of RFID antenna on the middle junction member during irregular cabling, if the middle junction member is provided with other functional modules, then the coil of RFID antenna can be according to the outline of the functional module that is provided with on the middle junction member irregular cabling, for example, consult shown in Figure 3, the middle junction member is provided with two and hollows out parts, these two hollow out parts can only be to hollow out design for what industrial design needed, promptly only possessing the design function, also can be other embedded devices, as, draw-in groove, camera or the like.With the coil of RFID antenna along the irregular cabling of the outline that hollows out parts that is provided with on the middle junction member, make the cabling mode of coil be not limited to " requiring each coil cabling all to take bigger area ", can farthest utilize limited design space to settle RFID antenna, increase the flexibility of design, and can not reduce the performance of RFID antenna.
Certainly, consult shown in Figure 3, preferable in order further to guarantee the data transfer performance of RFID antenna, with the outermost coil of RFID antenna outer largest contours cabling, thereby farthest satisfy the requirement of antenna magnetic flux along the middle junction member.
On the other hand, preferable, RFID antenna can adopt FPC (flexible PCB) material, and in walking line process, carries out suitable cutting out according to the concrete shape of middle junction member, hollows out, and bending is then with the adhesion mutually of middle junction member.Further, consult shown in Figure 4, RFID antenna is connected with circuit board of mobile phone by the connector that is arranged on the middle junction member, thereby can with other functional modules in the radio-frequency recognition system (as, read write line, radio-frequency card or the like) realize well connecting, on the cell phone rear cover, the dismounting probability reduces greatly, has further guaranteed the superperformance of handset identity antenna because connector is arranged on the middle junction member.
Among the utility model embodiment, redesigned the RFID antenna in the electronic installation, make RFID antenna be arranged in the electronic installation on the non-removable middle junction member, and the coil of RFID antenna is irregular cabling on the middle junction member, like this, just is not limited to cabling mode traditionally, efficiently utilized limited design space, improved the design flexibility of RFID antenna, and, also guaranteed the service behaviour of RFID antenna based on the stability of middle junction member.
