Technical field
The utility model relates to car machine field, particularly a kind of car machine antenna structure.
Background technology
Progress along with wireless technology, automotive electronic technology and automatic control technology, the integrated level of electronic machine is more and more higher, the upper integrated various functions of car machine (telematics) are more and more, various advanced persons' mechanics of communication begins to be applied on the car machine, the car machine is no longer an isolated equipment, and it can set up with the external world passage of an information interchange; The car machine on the basis of original bluetooth communication, the communication modes such as beginning integrating WIFI and 3G, the WIFI antenna that also brings simultaneously and 3G antenna integrated, at this moment, the mixing of multiple antenna is used, and prevents the phase mutual interference, needs to adopt special scheme to solve.
At present existing car machine solution, for guaranteeing the quality of wireless signal, FM antenna 1, gps antenna 2 and Bluetooth antenna 3 are all to adopt external mode, the inner mode of fly line or pcb board cabling that adopts of car machine is guided to radiofrequency signal the afterbody of car machine, be connected on outside different antennae module at the adaptor union by afterbody, adopt this kind mode mainly to have following problem:
(1) the aerial signal cable run distance is long, and signal attenuation is serious, as FM antenna 1, needs independent designing gain amplifier and amplifier feed circuit to be used for strengthening signal;
(2) cost is high, and radiofrequency signal is due to weak output signal, and the radio frequency axis need to be selected special quality coaxial signal line signal transmission, and special radio frequency connector, and overall cost is higher, and for example the design that has of FM antenna 1 is rear on glass, and cost is higher;
(3) install complicatedly, various antennas have concrete insulation request, need customized design installation site and wiring, often are arranged on tailstock top as the FM signal, need to route to console from the top of the tailstock, and the assembling cabling is very complicated.
The utility model content
The purpose of this utility model is to provide a kind of car machine antenna structure, in the situation that guarantee performance of antenna, has cancelled external antenna, the aerial signal decay is disturbed less, each other little, has reduced simultaneously cost, and compact conformation makes easy for installation.
Provide a kind of car machine antenna structure for this reason, comprise PCB module and central processing unit, described PCB module comprises antenna element, it is characterized in that, described antenna element is arranged on pcb board in the mode of printing Butut, and is connected with central processing unit by the printed circuit cable of pcb board.
Described antenna element comprises one or more in 3G antenna, WIFI antenna, gps antenna, FM antenna, BT antenna.
Preferably, when having multiple antenna, each antenna radio frequency one end and pcb board welding, the other end and radio-frequency module welding.
Preferably, the distance of each antenna distance metal object is greater than 10cm.
Preferably, antenna element comprises the 3G antenna, and to reserve maximum area on pcb board the 3G antenna be 30 * 50mm
