Abstract

The utility model discloses a vehicle lamp error indicator circuit, so as to provide error prompt for all kinds of lamp errors with a display in a vehicle operated by a driver. The utility model is a circuit combined with a plurality of electric units according to the number of vehicle lamps under monitor; each electric unit comprises a relay, a resistor, a diode, an LED and a lamp under monitor connected with a power source. Inside the vehicle, the circuit to resolve the problem of difficulty in observing whether a lamp fails during operation of prior vehicles is arranged. The utility model can make the driver in the cab identify in time, according to the ON/OFF indication of flash tubes (indication lamps), whether a front or rear lamp fails on the vehicle as well as specific reasons. Meanwhile, the utility model can provide convenience in timely overhaul and maintenance, so as to avoid accidents from happening during fining process by traffic police or due to lamp insufficiency. The utility model has the advantages of simple assembly and convenient utilization.

Description

Car bulb fault prompting device circuit

Technical field

The utility model relates to a kind of car bulb fault prompting device circuit, is mainly used in the prompting that driver drive motor shows that various lamps break down.

Background technology

At present, light before and after the general automobile, comprise stoplight stop lamp, lampet, backing-up lamp, steering indicating light, headlight, registration mark light etc., in a single day break down under steam, often because the driver in time finds to handle, impose a fine deduction of points and be subjected to the traffic police, more main is, if the driver in driving, can not handle the fault that light takes place, traffic accident then very easily takes place, and causes car crash.It is reported that in the automobile of higher gears a kind of prompting device junction circuit of people's design and installation is arranged, but it can only point out simply the driver that the light et out of order is arranged, and can not specifically point out a certain lamp et out of order and reason thereof, can only stop by the people and search, very inconvenient.

Utility model content the purpose of this utility model is exactly for solving the above problems, and for people provide a kind of car bulb fault prompting device circuit, its can actv. be pointed out to the driver, and certain light breaks down and reason at any time in the running car.

The purpose of this utility model realizes by following technical measures:

This circuit is made up of several electric units, each electric unit divides control, prompting, monitor three parts, said control part comprises relay, resistance, first diode and second diode, notification portion comprises flashing diode, monitor portion comprises the 3rd diode and monitored light, its junction circuit is the A termination power of relay, C holds series resistance, first diode, flashing diode ground connection, B termination second diode cathode, continuous the 3rd diode cathode of negative pole and monitored light inlet side, monitored light goes out to hold ground connection, the 3rd diode cathode connects the switch power connection, this integrated circuit can be according to monitored light quantity, and decision can be connected by N same electrical unit assembly.

The relay of described control part, resistance, first diode and second diode are integrated in the box body.

Advantage of the present utility model, on automobile, be equipped with this prompting device circuit, can be bright or do not work according to prompting flashtube (indicator lamp), making the driver in time judge automobile front and back light lamp in operator's compartment breaks down and reason, lamp is spoilt or bad contact in this way, is that the fuse blew out or switch problem, comes into plain view, be convenient to the driver and in time overhaul, avoid the generation of people's car accident.Assembling is simple, and is easy to use.

Description of drawings

Below with reference to accompanying drawing the utility model embodiment is elaborated:

Fig. 1 is the utility model circuit block diagram.

Fig. 2 is the utility model integrated circuit connection diagram.

The specific embodiment

Shown in Fig. 1,2, the utility model by 1,2, a 3-N electric unit connects to form, each unit divides control (3), prompting (2), monitoring (1) three part, said control part comprises relay J DQ, resistance R, the first diode VD ₁With the second diode VD ₂, notification portion comprises flashing diode LED, monitor portion comprises the 3rd diode VD ₃With monitored light DG, every unit junction circuit is the A termination power V of relay J DQ, C end series resistance R, the first diode VD ₁, flashing diode LED ground connection T, the B termination second diode VD ₂Positive pole, negative pole the 3rd diode VD that links to each other ₃Negative pole and monitored light DG inlet side, monitored light DG goes out to hold ground connection T, the 3rd diode VD ₃The anodal K switch power connection V that connects, this circuit is according to monitored light DG quantity before and after the automobile, determines that several same electric unit connection is combined into integrated circuit.

The relay J DQ of the utility model circuit control part, resistance R, the first diode VD ₁With the second diode VD ₂Be integrated in assembling in the box body.
