Abstract
The utility model discloses a kind of connection structures of automobile Rear Position Lamp, including the taillight A that is fixed on vehicle body and with taillight A cooperations, be fixed on the taillight B of rear cover；The taillight A, taillight B are separately connected vehicle body power supply, and body of a motor car includes signal control circuit, is connected by signal harness, the current compensation circuit of taillight A, pass through the diode connection signal harness of directional signal control circuit；The signal harness is inserted into earthing switch；Signal control circuit is directed toward the diode of current compensation circuit with the connecting pin access of signal harness.By adding a signal wire in vehicle body circuit so that automobile can identify that rear cover is opened or B lamps fail the situation not worked to carry out current control by feedback signal, meanwhile, by the low bright state of the compound realization Brake lamp of signal wire to carry out light type correction to A lamps.
Description
Technical field
The utility model is related to auto parts field more particularly to a kind of control circuits of automobile tail light.
Background technology
Existing automobile tail light is traditionally arranged to be combination tail lamp, and due to the presence of rear cover, thumping majority combination tail lamp is A+B
Lamp form, i.e. back light are divided into two regions, and A lamps are in non-post cover area, are installed on affixed side, and B lamps are covered after being in, are installed on
Drawer at movable side.
Current standard regulation, under the premise of A lamps and B lamp moulding tendencies are continuous, A lamps need brightness to want energy when rear cover is opened
Individually meet regulation, meanwhile, after rear cover lid closes, the brightness of A, B lamp meets regulation and is unable to excess.
Since current vehicle mostly uses inclined moulding, cause the offset of A lamplight types very serious, has often resulted in when A lamps are rigid
When meeting regulation well, if adjusting B lamps brightness is consistent with A lamps, then being susceptible to test zone after A lamps are lighted simultaneously with B lamps
The case where brightness maxima excess.And in order to avoid superbright, since A lamps do not have the space of reduce brightness, the bright of B lamps can only be reduced
Degree, this causes A lamps and is mismatched with B lamp brightness, that is, is difficult to meet matching and the laws and regulations requirement of A, B lamp brightness simultaneously again.
Utility model content
The purpose of this utility model is in order to overcome the problems referred above, to propose a kind of connection structure of automobile Rear Position Lamp, pass through
A signal wire is added in vehicle body circuit so that automobile can identify what rear cover opening or the failure of B lamps did not worked by feedback signal
Situation is to carry out current control, alternatively, being rectified by the low bright state of the compound realization Brake lamp of signal wire to carry out light type to A lamps
Just.
A kind of connection structure for automobile Rear Position Lamp that the utility model is proposed, including the taillight A that is fixed on vehicle body
And coordinate, be fixed on the taillight B of rear cover with taillight A；The taillight A, taillight B are separately connected vehicle body power supply,
Body of a motor car includes signal control circuit, is connected by signal harness
The current compensation circuit of taillight A passes through the diode connection signal harness of directional signal control circuit；
The signal harness is inserted into earthing switch；
Signal control circuit is directed toward the diode of current compensation circuit with the connecting pin access of signal harness.
In use, when boot is opened, A lamps send out low level signal to signal control circuit to the left and right, by sensor circuit
Identify that low level signal, electricity frequency switch are closed, compensation circuit generates compensation electric current and flows through body side ground connection, improves A lamp brightness.
When boot is closed, signal control circuit gives left and right A lamps hanging signal, low hanging letter is identified by sensor circuit
Number, electricity frequency switch disconnects, and leakage current does not exceed required value under diode action at this time, and uncompensated electric current generates, A lamp brightness
It is reduced to consistent with B lamps.
That step, in order to avoid signal interference, the signal control circuit includes power supply and low frequency filtering circuit.
Further, the low frequency filtering circuit is ground capacity.
Description of the drawings
Fig. 1 is the vehicle body tail lamp structure schematic diagram of the utility model.
Fig. 2 is the circuit diagram of the utility model
Fig. 3 is the control principle drawing of the utility model.
Specific implementation mode
In order to make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, under
Face combines diagram, and above-mentioned technical proposal is expanded on further.
A kind of connection structure of automobile Rear Position Lamp as shown in the figure, including the taillight A and and tail that are fixed on vehicle body
Lamp A cooperations, the taillight B for being fixed on rear cover；The taillight A, taillight B are separately connected vehicle body power supply,
Body of a motor car includes signal control circuit, is connected by signal harness
The current compensation circuit of taillight A passes through the diode connection signal harness of directional signal control circuit；
The signal harness is inserted into earthing switch；
Signal control circuit is directed toward the diode of current compensation circuit with the connecting pin access of signal harness.
The signal control circuit includes power supply and low frequency filtering circuit.
The low frequency filtering circuit is ground capacity.
Basic principles, main features, and advantages of the present invention has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, the utility model can also on the premise of not departing from the spirit and scope of the utility model
There are various changes and modifications, these various changes and improvements fall within the scope of the claimed invention.The utility model is wanted
Protection domain is asked to be defined by appended claims and its equivalent.
