After receiving the fault signals sent out by the vehicle lamp sensor, the control circuit of the utility model controls the warning device to send out the warning.
Description
Technical field
The utility model relates to a kind of car light failure warning device, particularly (comprise head light, side light, preceding indicator and fog lamp etc. relevant for the employed head lamp of a kind of vehicle, below be referred to as head lamp) and the failure warning device of taillight (comprise tail lampet, stoplight stop lamp and tail indicator etc., below be referred to as taillight).
Background technology
Automobile or locomotive (following general designation car) are the indispensable vehicle of modern, yet car head lamp and taillight are equivalent to the eyes of car, when the car light fault, be easy to cause danger and accident, yet by day the time, if steerman is not done the safety inspection before the driving, usually can not find car light and have fault, just find during to night or bad visibility, but late, cooresponding danger.
In addition, during the head lamp et out of order in general car the place ahead, steerman is easy to do with regard to finding the action of replacing, however the taillight et out of order of tailstock portion can be not bright the time, and general steerman is not easy to find, under the situation as if night or bad visibility during driving, the vehicle in the vehicle that can cause rear the place ahead not to be noted or when not seeing Chu, and traffic accident or accident take place, therefore with regard to safety, taillight fault dangerous in addition than head lamp come serious, and be easy to out in the cold.
Summary of the invention
The purpose of this utility model is to provide a kind of car light failure warning device, can be used for detecting the fault of car light bulb and giving a warning.
The purpose of this utility model can realize by following measure:
A kind of car light failure warning device comprises:

Description of drawings
Fig. 1 is a circuit box scheme drawing of the present utility model; And
Fig. 2 is an embodiment circuit diagram of the present utility model.
The specific embodiment
See also shown in Figure 1ly, be circuit box scheme drawing of the present utility model.Car light failure warning device of the present utility model mainly is to be used for detecting car light whether to produce fault, this car light comprises the head lamp (comprising head light, side light, preceding indicator and fog lamp etc.) that is arranged at car the place ahead and the taillight (comprising tail lampet, stoplight stop lamp and tail indicator etc.) of car afterbody, when the car light et out of order, send caution immediately, and this caution can be for emitting beam, perhaps send caution sound, to remind steerman.
But each car light of the utility model all is provided with a sensor, and perhaps all car lights are shared a sensor.Be simplified illustration, present embodiment is to share a sensor with all car lights to describe.Car light failure warning device of the present utility model includes a car light sensor 11, one control circuit 12 and an alarming device 13, wherein this car light sensor 11 is connected at least one car light bulb 14 circuits, in order to detect the faulty condition of car light, this car light sensor produces a fault signal to this control circuit 12 when the car light fault, the input end of this control circuit 12 is connected in this car light sensor 11, and this alarming device 13 is done in the mouth connection, when this control circuit 12 receives this fault signal, then control the alarm signal that this alarming device 13 sends light or sound, reach the purpose of notice steerman.
See also shown in Figure 2, be embodiment circuit diagram of the present utility model, this car light sensor 11 is current potential comparator circuits in the present embodiment circuit, V2 (-) pin (22) by one first comparator U1 (21) is connected on the bulb circuit of this car light, V3 (+) pin (23) of the first comparator U1 (21) then is connected on the default bias of a resistor R 5 (24), when car light bulb 14 just often, V2 pin (22) current potential of this first comparator U1 (21) is greater than V3 pin (23) current potential, and the output V1 pin (25) of this first comparator U1 (21) is an active potential, i.e. the trouble free signal; When these car light bulb 14 faults did not work, V2 pin (22) current potential of this first comparator U1 (21) was less than V3 pin (23) current potential, and the output V1 pin (25) of this first comparator U1 (21) is a high potential, promptly produces this fault signal.
In the utility model embodiment circuit, this control circuit 12 is made up of one second comparator U2 (26); V5 (+) pin (27) of this second comparator U2 (26) is connected in the V1 pin (25) of this first comparator U1 (21) via a resistor R 7 (28), promptly in order to receive this fault signal; V6 (-) pin (29) of this second comparator U2 (26) then is connected on the reverse blas of a Zener diode Z1 (30), this V6 pin (29) is gone up obtained a default positive electricity place value.When the V1 pin (25) of this first comparator U1 (21) is active potential (trouble free signal), then this V5 pin (27) is an active potential, and the output V7 pin (31) of this second comparator U2 (26) also is an active potential, therefore can't drive a transistor Q2 (32), make this transistor Q2 (32) produce open circuit, therefore can't drive this alarming device 13; When the V1 pin (25) of this first comparator U1 (21) is high potential (the fault signal is arranged), V5 pin (27) current potential of this second comparator U2 (26) is greater than this V6 pin (29) current potential, then this V7 pin (31) then is a high potential, thereby make this transistor Q2 (32) conducting, therefore can drive this alarming device 13 sends caution.
This alarming device 13 of the present utility model can be a Warning light 15, and LED lamp for example perhaps can be a buzzer phone 16 with luminous with as caution, with send-serge-serge-sound is as caution, perhaps Warning light 15 and buzzer phone 16 usefulness also.The utility model comprises that also a power circuit 17 is connected in this control circuit 12, and this power circuit 17 is formed a mu balanced circuit by a voltage stabilizing crystal Q1 (33), provides this control circuit 12 required stabilized power source.
The above person only is the present invention's preferred embodiment wherein, is not to be used for limiting practical range of the present invention; Be that all equalizations of being done according to the present patent application claim change and modification, be all claim of the present invention and contain.
