Abstract
The utility model discloses a motor vehicle light warning device, containing a shell, a circuit board and a speaker arranged inside the shell, and a power amplification circuit connected with the speaker. The utility model is characterized in that a sampling circuit on the circuit board is connected with a signal amplification circuit, and the signal amplification circuit is connected with a examination and comparison circuit, and the examination and comparison circuit is connected with a judging circuit, and the judging circuit is connected with a correction circuit, the correction circuit is connected with the power amplification circuit and/or a light indication circuit with indication light. The utility model provides a motor vehicle light warning device, which can indicate the damage situation of the steering light and the stoplight of the vehicle, the forecast ratio of the malfunction is high, the safety coefficient is large, and the safety of drivers during travelling can be greatly improved, and can also avoid the penalty for violating the regulations, and prevent the hidden trouble of traffic accidents, furthermore, the self working electric current is 2 milliampere, thereby to the circuit, no load can be increased, at the same time, the input and output terminals of the product are arranged with 10A double two circuit fuse electrical connector, which is a double insurance for the whole vehicle and the product, and at the same time, the structure of the product is reasonable, thus high economic value and practical value are provided, and the utility model is easy for popularization.
Description
Technical field:
The utility model relates to the technical field of motor vehicle fittings, specifically a kind of automobile lamplight annunciator.
Background technology:
Raising day by day along with people's living standard, family-sized car, the quantity of self-propelled vehiclees such as commercial affairs passenger vehicle is also in continuous increase, the frequency of utilization of stoplight stop lamp and steering indicating light is higher in the accessory inside and outside self-propelled vehicle, its damage rate is relatively also higher, because in use rush current is big, cause fault and indicator lamp to burn out easily, and its fault detection is a difficult problem always, because manufacturer does not allow to increase the wire harness of instrument to car light, do not allow in the loop, to add the components and parts of any resistance coil and so on yet, especially when wherein a bulb damages, the variable quantity of its impedance is very little, is difficult to detect, moreover, the resistance value error of new used car vehicle light circuit is very big again, has brought difficulty to detection more.
Summary of the invention:
The purpose of this utility model is to provide a kind of automobile lamplight annunciator, and it can overcome some shortcomings of the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of automobile lamplight annunciator, it comprises housing, be arranged on circuit card and loud speaker in the housing, with loud speaker bonded assembly power amplification circuit, it is characterized in that: the sample circuit on the described circuit card connects signal amplification circuit, signal amplification circuit joint detection comparator circuit, detect comparator circuit and connect judging circuit, judging circuit connects calibration channel, and calibration channel connects power amplification circuit and/or has the light indicating circuit of indicator lamp.Self-propelled vehicle provides DC12V operating voltage for sample circuit.
The utility model provides a kind of automobile lamplight annunciator, it can point out the damaged condition of vehicle turn signal and stoplight stop lamp by acousto-optic, failure prediction rate height, safety factor is big, can improve driving person's security row under steam greatly, also avoided damaging the Default penalty that causes because of car light, the hidden danger that more tries to forestall traffic accidents, in addition, itself working current is 2 milliamperes, circuit is not increased load, simultaneously product patches at the two-way fusing insurance electricity that output and input end all are provided with 10A, and to car load and product double insurance, the while product structure is reasonable, very high economic value and practical value are arranged, be easy to promote.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model schematic circuit diagram.
Referring to Fig. 1, Fig. 2.The utility model mainly comprises: housing 1, be arranged on circuit card 2 and loud speaker 3 in the housing 1, with loud speaker 3 bonded assembly power amplification circuits 4, it is different from prior art and is: the sample circuit 5 on the described circuit card 2 is connected with signal amplification circuit 6, signal amplification circuit 6 is connected with detection comparator circuit 7, detect comparator circuit 7 and be connected with judging circuit 8, judging circuit 8 is connected with calibration channel 9, and calibration channel 9 connects power amplification circuit 4 and has the light indicating circuit 10 of indicator lamp 11.
The specific embodiment:
Referring to Fig. 1, Fig. 2.At first pass through sample circuit, to signal amplification circuit, detect comparator circuit then, if it is good detecting, it arrives light indicating circuit by calibration channel, and the interior indicator lamp (indicator lamp is respectively stoplight stop lamp, indicator) of indicator lamp holder (not providing in the accompanying drawing) in the light indicating circuit is lighted synchronously, represent that all are normally intact.If it is bad detecting, the indicator lamp flicker in the indicator lamp holder is reported to the police, the outer indicator lamp et out of order of expression car.If the indicator lamp in the indicator lamp holder does not work (when foot brake or indicator are opened), expression BK Brake Switch, indicator mechanical switch switch et out of order, no-output electric current.So the outer indicator lamp of car all around one do not work yet, by the indicator lamp holder caution, the person for driving a car is come into plain view to all kinds of faults.
The utility model also can make indicator lamp caution or loud speaker audio alert respectively.
