Description
Technical field
The utility model smart mobile phone technical field refers to a kind of smart mobile phone with radio frequency card-reading function especially.
Background technology
Along with development of electronic technology, smart mobile phone obtains popularizing more and more widely, and its user namely comprises the personal user, also comprises the business user, and just constantly thinner towards thickness, screen size is bigger, the CPU disposal ability is stronger, the more direction of integrated functionality develops.The general intelligence mobile phone mainly comprises screen (comprising display screen and touch-screen), be provided with circuit board (also have between circuit board and screen and increase division board) at the screen back side, the general back side of this circuit board is (towards the body front, substantially do not have electronic component) and screen back side butt, positive (towards the body back side, have most of electronic component and tie point) be provided with the shielding circuit board cover, the tie point of circuit board also is connected with spare and accessory parts such as antenna for mobile phone, battery case, draw-in groove, button and connectivity port simultaneously, installs back cover afterwards again additional.
Simultaneously, REID is a kind of by radio signals identification specific objective and read and write the technology of related data, and it need not to set up machinery between recognition system and the specific objective or optics contacts, the while good reliability, therefore application is very wide, as: the library, gate control system, food security are traced to the source etc.General radio-frequency recognition system need comprise radio electronic label and radio-frequency card reader, and wherein radio-frequency card reader comprises fixed and portable two kinds.Wherein Yi Dongshi radio-frequency card reader is more and more important in the effect of commercial application facet aspects such as (for example) logistics systems, yet is equipped with radio-frequency card reader cost height not only for individual and businessman separately, nor makes things convenient for.Therefore radio-frequency card reader is gathered to smart mobile phone, utilized the powerful CPU disposal ability of smart mobile phone to realize the more and more mobile radio card reader developer's of card-reading function selection.
Yet radio-frequency card reader gathered to smart mobile phone but have a problem: though smart mobile phone can increase the function of handling radiofrequency signal easily on circuit, yet there are problems in the position that arranges of radio-frequency antenna (radiofrequency signal receiving system).Because the major function of antenna is to produce magnetic field and received RF signal, what therefore main need were considered for antenna is exactly the battery shielding, electromagnetic interference and the power density (coupling distance when this has influence on Card Reader that produces magnetic field, be decipherment distance), based on use habit, the general selection of existing technology is arranged at mobile phone back cover place with radio-frequency antenna, radio-frequency antenna sees through back cover, yet element is numerous herein, be easy to generate the phase mutual interference, be unfavorable for the radio-frequency antenna setting, the radio-frequency antenna of coil type particularly, therefore the layout designs near the spare and accessory parts the mobile phone back cover requires very high, if the increase cage is isolated spare and accessory parts then not only can be increased smart mobile phone thickness, and can increase huge cost.
For this reason; patent document CN 201222260Y discloses a kind of display unit with wireless identification system function; it is on the one hand by adopting the radio-frequency antenna of diaphragm type; and before radio-frequency antenna is arranged between frame shell and the diaphragm, and then preceding frame shell is worn groove so that radio-frequency antenna is connected with circuit board of mobile phone.Though this method has been avoided radio-frequency antenna is arranged on the defective that bring at the mobile phone back side substantially, but also bring new deficiency: (1) this technical scheme can only arrange on the bigger display unit of former frame shell, the frame shell has enough areas that radio-frequency antenna can be set before for panel computer, but the frame shell is generally very little before for smart mobile phone, and more and more littler trend arranged, substantially after being set, membrane keyboard just do not had unnecessary space, therefore this technical scheme scope of application is little, particularly is not suitable for smart mobile phone.(2) only can adopt the radio-frequency antenna of diaphragm type, can't adopt the radio-frequency antenna of coil type or circuit board type, alternative low, cost height simultaneously, its power density that produces magnetic field is also comparatively effective.(3) need front plane frame is worn groove, increased the complexity of assembling, reduce efficiency of assembling, increased assembly cost.
Summary of the invention
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and the smart mobile phone with radio frequency card-reading function that a kind of applicability is strong and production cost is low is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of smart mobile phone with radio frequency card-reading function is provided, comprise body, described body front is provided with screen panel, inside is provided with circuit board, the back side of described circuit board is provided with radio-frequency antenna towards the back side of screen panel between described screen panel and the circuit board, described radio-frequency antenna and screen panel butt, described circuit board is provided with radio frequency and reads chip, and described radio-frequency antenna connects radio frequency and reads chip.
Wherein, described radio-frequency antenna is the coil type radio-frequency antenna that arranges around screen panel.
Wherein, be provided with insulating barrier between described radio-frequency antenna and the circuit board.
Wherein, described radio frequency reads chip and is connected with mobile phone CPU.
Wherein, the back side of described radio-frequency antenna is coated with electromagnetic shielding film.
The beneficial effects of the utility model: the utility model is arranged at the screen back side with radio-frequency antenna, and radio-frequency antenna sees through screen and produces a magnetic field to respond to close radio electronic label.Because the screen size of smart mobile phone is enough big and increasing, and the screen back side does not have electronic component (near back of circuit board or division board) substantially, therefore guaranteeing has enough spaces that radio-frequency antenna can be set, and can not be subjected to electromagnetic shielding or electromagnetic interference.The utility model namely need not to considering how to evade the spare and accessory parts at back cover place, and the size of frame shell near the layout of the spare and accessory parts mobile phone back cover and the equal no requirement (NR) of size of preceding frame shell, has improved its applicability greatly before also need not to consider; Simultaneously also need not to increase parts such as cage, and when being arranged at the screen back side near circuit board, be convenient to very much be connected with circuit board, improved efficiency of assembling, reduce whole cost; In addition owing to can select different radio-frequency antenna (as coil type, diaphragm type etc.) according to actual conditions, and the space that radio-frequency antenna can be set is enough big, therefore can effectively improve the power of radio-frequency antenna, the radome of recycling circuit board concentrates on by screen the transmitting power of radio-frequency antenna to launch, improved the power density of antenna greatly, improve coupling distance, both improved the Card Reader distance.
