The specific embodiment

By reference to the accompanying drawings the utility model is described in further detail below by the specific embodiment.

As shown in Figure 1, electronic flasher in the embodiment of the present application comprises electronic flasher housing 100 and the electronic flasher circuit that is placed in housing, and the electronic flasher circuit comprises input end 101, mouth 106, ON-OFF control circuit 102, decoding scheme 103, display driver circuit 105, counting machine 104.ON-OFF control circuit 102 is coupling between input end 101 and decoding scheme 103, display driver circuit 105 is connected between decoding scheme 103 and mouth 106, ternary counter 104 connecting valve control circuits 102 and decoding scheme 103, ON-OFF control circuit 102 also is connected with display driver circuit 105.

In a kind of specific embodiment, the electronic flasher circuit also comprises oscillating circuit 107, and oscillating circuit 107 is connected with ON-OFF control circuit 102 sum counters 104 respectively, in other embodiments, also can not comprise oscillating circuit.Due to automobile tail light what light indication is the action that this car will occur, so the taillight of automobile can not surpass certain frequency in flicker, but frequency can not be too little, general dutycycle is about 50%, after oscillating circuit 107 produces impulse singla, just can control automobile tail light time gap when circulation is lighted by counting machine 104 and be about 0.5S, thereby so just can allow the people very clearly understand the generation of action to take corresponding avoiding action more effectively to avoid traffic accident of this automobile.

Further, counting machine is ternary counter 104, and in a further embodiment, counting machine also can consist of or be replaced by the integrated counter transformation for the flip-flop stages connection.Compare with the circuit structure of other counting machine, directly relatively simple with ternary counter.It is that " 1 " or " 0 " provide 2 to the switching variable that it provides that ternary counter 104 is accepted input end ³=8 kinds of taillight control signals (in fact only needing 4 kinds), when the control signal of decoding scheme 103 outputs was low level, corresponding indicator lamp was bright.

Decoding scheme 103 provides the taillight control signal under the effect of ON-OFF control circuit 102 outputs and ternary counter 104, when the control signal of decoding scheme 103 outputs was low level, corresponding indicator lamp was lighted.

As shown in Figure 2, circuit diagram for a kind of concrete electronic flasher, consist of the signal of

generation

01,10,11 3 kind of cycle of states by 74LS 160 ternary counters, and then converting thereof into required 001,010,100 3 kind of signal that turns left or turn right by decoding scheme, mouth connects 6 light-emitting diode D ₁-D ₆Wherein decoding scheme comprises 3-8 line decoder 74LSl38,6 phase inverters and 6 and door, three input end A of 74LSl38 ₂, A ₁, A ₀Meet respectively S ₁, Q ₁, Q ₀, and Q ₁, Q ₀It is the mouth of ternary counter.Work as S1=0, enable signal A=G=1, the state of counting machine are 00,01,10 o'clock, the mouth that 74LSl38 is corresponding

Be followed successively by 0 effectively (

Signal is that " 1 " is invalid), phase inverter G ₁-G ₃Mouth also be followed successively by 0, therefore indicator lamp D ₁→ D ₂→ D ₃Light in order, the signal Automobile Right is turned.If above-mentioned condition is constant, and S ₁=1, mouth corresponding to 74LSl38

Be followed successively by 0 effective, i.e. phase inverter G ₄～G ₆Mouth be followed successively by 0, therefore indicator lamp D ₄→ D ₅→ D ₆Light in order signal automobile turnon left.Work as G=0, during A=1, the mouth of 74LSl38 is 1, G entirely ₆～G ₁Mouth be also 1 entirely, indicator lamp goes out entirely, the signal automobile advance; Work as G=0, during A=CP, indicator lamp is with the frequency scintillation of impulse singla CP, the signal braking automobile.Owing to travelling and braking, enable signal G=0, output end signal is consistent, available same connection, when operation, namely A=1 represents to travel, and A=CP represents brake.In addition, because oscillating circuit can have multiple circuit mode, therefore not shown in Fig. 2.

As shown in Figure 3, input end 101 is six line input ends processed, and mouth 106 is the four-wire system mouth.The current signal of 101 input termination storage batterys or other mains connection set, 106 mouth output low level signals.

In a kind of concrete embodiment, input line and output line can have following wiring (color) mode: (the terminals shown in the digital 1-6 of the left side input end 101 in its left 1-6 presentation graphs 3; Terminals shown in the digital 1-4 of the right mouth 106 in right 1-4 presentation graphs 3.）

As above shown in the table, when automobile was turned left, combined switch was beaten turn signal swich left, electric current flow to yellow red line through the left steering light switch, provides an incoming signal to electronic flasher, electronic flasher is the output low level signal just, flow to brown white line to the left steering lamp, and the left steering lamp is lighted.

When automobile bent to right, combined switch was beaten turn signal swich to the right, and electric current is through the right steering light switch, flow to yellowish-white line, provide an incoming signal to electronic flasher, electronic flasher is the output low level signal just, flow to green white line to the left steering lamp, the right steering lamp is lighted.

When automobile was advanced forward, combined switch was beaten to driving/stoplight stop lamp, and electric current is through driving/braking signal switch, flow to brown line, provide an incoming signal to electronic flasher, electronic flasher is the output low level signal just, flow to extremely driving/stoplight stop lamp of white deceiving/blue-black line, driving/stoplight stop lamp extinguishes.

When braking automobile, combined switch is beaten to driving/stoplight stop lamp, and electric current is through driving/braking signal switch, flow to greenish-yellow line, provide an incoming signal to electronic flasher, electronic flasher is the output low level signal just, flow to white deceiving/blue-black line to driving/stoplight stop lamp, driving/brake light flicker.

By common row car light and stoplight stop lamp, other control path, can reduce by one tunnel control path relatively.

In other embodiments, also can select different wiring (color) mode.

As shown in Figure 5, the application's electronic commutator also comprises insulating gum cover 200, and wiring 101 is input end, and wiring 106 is mouth, and insulating gum cover 200 is enclosed within on electronic flasher housing 100, and is fixed on installation iron plate on automobile.In a kind of concrete embodiment, electronic flasher housing 100 profiles are black plastic spare, and are all-sealed, and water resistance is good.

The application's electronic flasher not only can obtain stable horsepower output, and be intelligent control, can effectively improve the safety of running car, minimizing is the slow in reacting or generation that error in judgement causes the accident because of the people, actv. has overcome the defective that electronic flasher horsepower output in the past easily is subject to the various factors impacts such as intensity of current, ambient temperature on power supply, and give the extraneous correct information of passing on, make orderly the advancing of automotive safety, the generation that the energy actv. avoids traffic accident.

In addition, the application adopts six lines to advance the mode that four lines go out, and has reduced one road control path than general control path, and I/O mode is simple and practical, and compact conformation is easy to operate.

Above content is in conjunction with concrete embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace.
