Description
Technical field
The utility model relates to automotive field, in particular to a kind of automobile multi-tap.
Background technique
With popularizing for automobile, the demand to automobile repacking is also constantly promoted, especially to the repacking demand of passenger car.Very
Multi-user is after buying automobile, it is believed that its original-pack configuration is insufficient for the demand of itself, often changes to automobile
Dress (industry commonly referred to as " rear dress "), such as installs or reequips navigation system, sound system and reverse image system additional.
It is filled after realizing automobile, it is necessary first to draw automobile from vehicle and control signal, as audible warning, steering wheel learn
Signal, ACC key switch signal, small light detection signal, automatic antenna power supply signal, reversing detection signal and ground signalling GND
With positive pole signal and reverse image video signal (Yuan Cheyou reverse image function), AUX (external source of sound) signal and
Usb signal etc.；And the setting of original Che Leida, vehicle functions and car running computer data etc..
Above-mentioned automobile control signal is segmented into three kinds: one is decoded signal is not needed, such as audible warning, automatic day
Line power supply signal, ground signalling GND and positive pole signal all do not need after drawing in the vehicle of any brand and model
It is decoded；Another kind is to need decoded signal, commonly referred to as vehicle data signal (former car data signal), such as original Che Leida,
The signals such as vehicle functions setting and car running computer data, are all to need to decode after drawing in the vehicle of any brand and model
's；In addition to this signal may exactly need decoded signal, be to need to decode in the vehicle of some brands and model
, in the vehicle of some brands and model, it may be possible to not need decoded.
One control signal output, including one or more plug can be generally set on existing vehicle.It is needed when filling afterwards
These plugs are inserted into socket by the socket for wanting one with plug cooperation, and harness and conducting wire, including one are then drawn on socket
A harness being connect with the public version plug of 16 needles (16pin).16 needle public affairs version plugs are industry plug generally used now, for drawing
Audible warning, steering wheel learning signal, ACC key switch signal, small light detection signal, automatic antenna power supply signal, reversing inspection
Survey signal and ground signalling GND and positive pole signal.The 16 needle public affairs version plug can be public with 16 needles on rear dress navigation host
Version socket cooperation, fills navigation host after the signal etc. drawn from control signal output is input to.If these certain signals
In it is in need decoded, it is also desirable to fill navigation host after being input to after decoding by 16pin public affairs version socket.
Other than the signal that 16 above-mentioned needle public affairs version plugs transmit, existing socket is also connected with output reverse image letter
Number, the conducting wire of AUX (external source of sound) signal and usb signal etc., the other end of these conducting wires is connected with plug, fills and lead after can be inserted into
Corresponding socket on boat host, fills navigation host after corresponding signal is transferred to.
It needs decoded vehicle data signal to be usually transferred to decoding protocol box to be decoded, these car datas are usually logical
Cross communication modes transmission below: such as CAN (Controller Area Network, controller local area network) bus, LIN
(Local Interconnect Network, Local Interconnect Network), MOST (Media Oriented System
Transport, multimedia orientation system transmission network), vehicle-mounted Ethernet and IEBUS (Inter Equipment Bus, equipment room
Bus) etc..In the prior art, it usually first passes through harness and draws vehicle data signal from vehicle signal output end, then pass through one
Plug is input to the decoder box (industry claims " agreement box ") for having decoding function, is decoded by agreement box to former car data, so
Decoded data are output to the expansion slot of multi-tap afterwards, pass through plug again by expansion slot and harness be transferred to after fill
Navigation host, also the vehicle data signal in this way by rear dress navigation host output is transferred to automobile.
So the tail end of existing automobile control signal plug, is inevitably connected with a large amount of harness and conducting wire, leads to
These harness and conducting wire is crossed to connect with agreement box, rear dress navigation host.These harness and conducting wire one side higher cost occupy sky
Between, handling it is inconvenient, on the other hand there is also because of natural risk caused by harness and conducting wire short circuit.
