The utility model is suitable for the automatic monitor of the operating states of various signal lamps for various motor vehicles, such as steering lamps, brake lamps, indicator lamps at night, etc. The utility model has the advantages of simple structure, low cost, no need of changing any circuit in motor vehicles for installation and exchange, convenient operation and reliable monitoring effect.
Description
The utility model relates to a kind of motor vehicle signal lamp routine, be applicable to various power actuated vehicles steering indicating light, brake lamp, night side-marker lamp etc. and so on the automatic monitoring of various signal lamp mode of operations.
Along with the progress of society, automobile certainly will become the indispensable vehicle in people's life.The appearance of increasing various power actuated vehicles brings great convenience to people really, but the incidence of traffic accident also rises thereupon.One of important measures that reduce traffic accident are that illuminating lamp, signal lamp are installed on various vehicles, and keep it intact, with guarantee driving safety.
The signal lamp of various self-propelled vehiclees has several, and main and requisite have: steering indicating light, brake lamp, night the side-marker lamp.For illuminating lamp, as long as switch opens, if lamp does not work, chaufeur is easy to discover.But signal lamp is then different, and particularly taillight when chaufeur opening signal light switch, is out of order as if circuit, and perhaps signal lamp damages, and chaufeur can't be known in operator's compartment, thereby increase the danger of driving.
In order to address this problem, the patent No. is that 85201897 Chinese patent adopts and contains the tab style turn signal lamp Der Blink und Abblendschalter that elastic alloy steel disc, metal tape, heating wire, contact, adapter plate are formed, and increases monitoring element that a dry-reed tube and induction coil form thereon and monitor whether et out of order of steering indicating light.Its weak point is only can monitor steering indicating light, and need use flasher to the spy that the flasher of all vehicles changes this patent into.This uses this technology to cause the trouble and the waste of installation, transposing for the vehicle of different model.
The purpose of this utility model provides a kind of motor vehicle signal lamp routine, but original device that it need not change various self-propelled vehiclees is direct mount just, only need connect it, when chaufeur is stepped on brake or opening signal light switch, if there are one or more signal lamps not work, its sound light alarming circuit is just immediately to the chaufeur caution, thereby the traffic accident that can avoid some to take place.
Realize the technical solution of the utility model: adopt electronic components such as the diode the most common, that cost is minimum, aerotron, resistance, electric capacity to form supervisory circuit, with the NE555 timer is the main warning circuit that constitutes, and both lump together and can reach the purpose of this utility model.This device adopts the dc battery jar power supply power supply of self-propelled vehicle.Signal lamp just often, it is worked hardly, has only in the circuit and small electric current, detects when the little sample resistance of signal lamp serial connection changes this electric current, handles through supervisory circuit, and this signal is delivered to warning circuit, at last with sound, the light display alarm.
The utility model is with respect to the advantage of prior art:
1, do not need additional power source, and adopt power sources of motor vehicle as power supply of the present utility model.
2, the element that is adopted is the electronics package of long, dependable performance of common, inexpensive, life-span, and its power consumption is little, cost is low.
3, technological requirement is not high, and principle is simple, and volume is little, is convenient to make, install circuit structure and the no specific (special) requirements of installation.
4, can carry out multi-path monitoring such as steering indicating light, brake lamp, night side-marker lamp simultaneously, increase and decrease is convenient, and at the steering indicating light scintillation duration, when disconnected, when perhaps power line voltage fluctuates, flase alarm can not occur between 8.5V-15V during IMU, and therefore monitoring is reliable.
Fig. 1 is supervisory circuit figure of the present utility model.
Fig. 2 is warning circuit figure of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing, and its structure and principle are further described.
One, structure
Referring to Fig. 1, by aerotron T1, T2, diode D0, resistance R b2, Rc1, Rc2 and signal lamp L1, L2 are serially connected with the Rx1 that Q1 orders and constitute the signal lamp testing circuit U1 that does not glimmer, and are used to monitor one road brake lamp.It is characterized in that described U1 is connected in series with signal lamp L1, L2 by little sample resistance Rx1, its point of connection Q connects the base stage of aerotron T1, the collecting electrode of T1 closes through the base stage lotus root of Rb2 and T2, and the collecting electrode of T2 links to each other with the input end P point of annunciator driving circuit U3 by diode D0.P point place connects the element circuit identical with U1 more in the drawings, can monitor another road brake lamp or night the side-marker lamp.Another monitoring unit circuit U 2 is flashing sign testing circuits, it is by aerotron T3, T4, diode D1, D2, existing flasher (B.L.E) on the self-propelled vehicle, resistance R c3, Rc4, Rb4 reach with signal lamp L3, L4 and are serially connected with the Rx2 formation that Q2 is ordered, be used to monitor one road steering indicating light, the monitoring of another road steering indicating light is identical therewith.Little sample resistance Rx2 is connected in series with steering indicating light L3, L4, and its point of connection Q2 connects as the base of aerotron T3, and the collecting electrode of T3 closes with the base stage lotus root of Rb4 and T4, and the collecting electrode of T4 links to each other with the input end P point of annunciator driving circuit U3 with capacitor C by diode D1, D2.When fault sometimes, logical when disconnected when making power supply because the effect of flasher (B.L.E), can cause warning off and on, capacitor C and diode D
2Form the elimination circuit of reporting to the police off and on, make annunciator continue to report to the police.Can connect some element circuits identical at P point place as required in the practicality, be used to control the signal lamp of the different purposes of multichannel with U1, U2.Among the figure by aerotron T5, T6, capacitor C 0, the element circuit U3 that resistance R 0, Rb5, Rc5, Rc6 are formed is the annunciator driving circuit.U3 input termination R0C0 filter circuit, aerotron T5, T6 constitute compound circuit, and the voltage V0 on the Rc6 is as the power line voltage of annunciator.Connecing the R0C0 filter circuit before the base stage of T5, mainly is to eliminate the instant alarm phenomenon.If certain reason makes collector voltage Vc2 or the collector voltage Vc4 of T4 or the high level output that both have moment of T2, may cause flase alarm.After adding the R0C0 filter circuit, can eliminate this phenomenon.The big I of R0, C0 differs the time decision by the voltage delay of T1, T2, also can be determined by experiment.
Referring to Fig. 2, warning circuit is by two NE555 integrated packages, LED, and loudspeaker or buzzer phone S, capacitor C 1, C2, C3 and resistance R 1, R2, R3, R4, R5, R6 constitute, and its power supply is provided by the V0 of supervisory circuit.
