Abstract
The utility model relates to a failure alarm indicator used for motor vehicle signal lights (tail light, stop light, and turn light). Using the failure alarm indicator, when in the event of the failure of the signal lights of the motor vehicle, the driver can be effectively reminded, while three kinds of conditions that (1) the signal lights are completely good, (2) one signal light is good, (3) the signal light are completely bad, can be judged according to the stations of an indicator light and a buzzer. The vehicle speed is higher and higher at present, and more accidents caused by the faults of the signal lights are followed. The accidents of the type can be effectively prevented from happening by using the failure alarm indicator, and the utility model plays a positive role in traffic safety.
Description
The utility model belongs to the accident indicator of the signal lamp (taillight, stoplight stop lamp and steering indicating light) of power actuated vehicle, can be used for the improvement of existing power actuated vehicle.
According to traffic regulation, power actuated vehicle under steam, taillight, stoplight stop lamp and steering indicating light must stand intact, because this is to other signals of vehicles, make the other side take the foundation of corresponding measure, but because these lamps all are installed in the outer and afterbody of car, break down and often do not know, this is a very big threat to safety traffic, the present invention that Here it is, problem to be solved.It is compared with existing same device, and it does not need magnet coil, and these have contact element dry-reed tube and relay, and long service life is reliable, and it can differentiate three kinds of different states 1. lamp is good entirely 2. one have to be 3. bad entirely.
The utility model by 1. special resistance sensor 2. this schmitt trigger 3. the sound and light alarm indicating circuit formed.
Engage light switch S 1, circuit enters mode of operation, if a signal lamp L1(or L2 are arranged) bad, then luminotron LED flashes, buzzer warning subsequently, if two are complete bad, then LED is not luminous, buzzer warning, if lamp is good entirely, then the luminous buzzer phone of LED does not ring.
Below we in conjunction with implementation procedure of the present invention being described with figure, engage light switch S 1, if two lamp L1, L2 is good entirely, voltage Vab>the 0.6V on special resistance Tr then, its triggers this schmitt trigger of being made up of T1 T2 R1 R2 R3 R4 R5 W1, T1 is satisfied close, T2 ends, at this moment T4 conducting, indicator lamp is bright, and T3 ends, buzzer phone is not worked, if two lamps are bad entirely, then Vab ≈ 0V does not have signal to be added on this schmitt trigger, and T1 ends, T2 is full to be closed T4 and ends, the T3 conducting, LED is not luminous, buzzer warning.If a lamp is bad,, be added to the voltage 0.6v>Vab>0v on this schmitt trigger then in the moment of closing S1, it makes the T1 conducting once, but cannot keep conducting, become again at once and end, the T2 pipe is just in time opposite, T2 is earlier by once, fullly subsequently close conducting, the T4 conducting once, LED flashes, the T3 conducting, buzzer warning.
The contriver was embodiment: get Tr ≈ 0.8 Ω, R1=120 Ω, R2=2.4K, R3=6.8K, R4=8.2K, R5=8.2K, R6=4.7K, R7=4K, R8=2K, W1=1K experimentizes with the small bulb of two 6w, and work-based logic is with top described identical.
Claims (4)
1, power actuated vehicle signal fault alarm indicator, by 1. special resistance sensor, 2. the Si Mite trigger circuit 3. and indicator lamp, the buzzer phone indicating circuit is formed.
2, be according to different vehicles and the little resistance resistance of purpose made Tr according to the described special resistance sensor of claim 1,
0.6E/W>Tr>0.3E/W, wherein E is a Battery voltage, and W is the power wattage of a bulb.
3, according to the described Si Mite trigger circuit of claim 1, by the positive-negative-positive aerotron T1 of two β>30, T2 and R1, R2, R3, R4, R5, W1 forms.
4, described according to claim 1, the lights indication, buzzer alarm circuit, the positive-negative-positive of two β>30 and NPN type aerotron and R6, R8, R7, LED and buzzer phone are formed.
