Description

Absorption type vehicle signal group lamp

The utility model relates to a kind of automobile signal light, belongs to vehicle electronics.

Automobile signal light is to be used for representing that the driver will carry out or ongoing operation, present vehicle signal, because employing is independent point source of light, so the content of operation of expression is limited, some operation can't be represented.For example: somerset, allow to overtake other vehicles etc., need add gesture and could represent, and its implication is also indeterminate, causes traffic accident easily.In addition, when the automobile close proximity, also cause the accident easily because the existing signal lamp of automobile is low.

The utility model is at above problem, and a read out instrument of being made up of one group of light emitting diode matrix and control circuit and adsorption element is provided.It is on glass it can be adsorbed on vehicle rear window, behind energized and the signal, need not any switch of adjunction, and the driver just can utilize original switch to reverse end for end or allow to overtake other vehicles signal aspect and indication on this telltale.Because telltale is placed in the primary vision area of vehicle rear window, so the effect of well warning is arranged.

The purpose of this utility model is achieved in that

Absorption type vehicle signal group lamp is made up of display panel, control circuit, adsorption element.Wherein display panel comprises the tune that light emitting diode matrix is formed and allows the pattern of overtaking other vehicles, as Fig. 1.Control circuit is by univibrator, isolation diode, and the long time delay integrator, the short time delay integrator, shift register, switching valve and relay are formed.The original steering indicating light wiring of automobile bypass is picked out, insert the input end of univibrator as the incoming signal of control circuit, univibrator to signal shaping output respectively through the input of two isolation diode spreadings time-delay integrators and short time delay integrator, the output of long time delay integrator connects the reset terminal of shift register, the short time delay integrator connects the input end of clock of shift register, shift register mouth and input shaper signal with after connect the base stage of switching valve, the collecting electrode of switching valve is connected in series with relay coil, the normal opened contact of relay links to each other with light emitting diode matrix, the break-make of control light-emitting diode.

When the driver need reverse end for end, as long as twice left-hand rotation lamp of switch, the tune pattern was just lighted on the display panel; When expression allows to overtake other vehicles, as long as twice right-hand rotation lamp of switch just allows the pattern of overtaking other vehicles on the display panel.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is a display panel pattern scheme drawing of the present utility model;

Fig. 2 is the control circuit schematic diagram;

R1, C1 connect the discharge pin (6 pin) of time base circuit 555 among Fig. 2, and C2 connects 555 control pin (5 pin), form single-shot trigger circuit and play the signal shaping effect.555 output pin (3 pin) connects the anode of isolation diode D1, and the negative electrode of D1 connects the anode of D2 and D3, and the long time delay integrator that is made of C3 and R2 parallel connection connects the negative electrode of D2, and the short time delay integrator that is made of C4 and R3 parallel connection connects the negative electrode of D3.Shift register 4015 input end of clock (1 pin) connect the short time delay integrator through twice anti-phase output.The data input pin of shift register (15 pin) power connection, reset terminal (14 pin) spreading time-delay integrator is through anti-phase mouth.Incoming signal after the output Q1 of shift register (12 pin) and the shaping and back output connect the base stage of switching valve.The coil of relay is connected on the collector loop of switching valve, and the Chang Kaiduan of relay links to each other with light emitting diode matrix and inserts power supply, as the master cock of diode array.

As long as the steering indicating light master cock is dialled to an end, the pulse sequence signal that allows control turn to enters when automobile need reverse end for end or allow the back to overtake other vehicles.Because the effect of integrator and phase inverter outputs to the clock of shift register and the signal of reset terminal is respectively pulsation-free high level and low level.Then, turn off pole changer, the mouth of short time delay integrator is reduced to low level after the several seconds, and the long time delay integrator also remains high level.At this moment open pole changer again, the output of short time delay integrator is from low level rebound high level again, twice triggering of the clock end of shift register makes Q1 (12 pin) output high level like this, with input redirect signal and rear drive switching valve, and then the driving relay, light tune or allow the pattern of overtaking other vehicles.
