Abstract
The utility model discloses a brake light fault alarm device for an automobile, which is especially designed to solve the problem that automobile rear-end collision accidents often happen because a brake light does not radiate. The utility model is composed of two series resistors R1, R3 and a luminous tube LED1 which are connected in series. The resistance value of the resistor R1 is much larger than the resistance value of the resistor R3 adjacent to the luminous tube LED1. Both ends of the series branch are respectively connected with the positive and the negative poles of an automobile storage battery. The intermediate node of the two resistors is provided with a lead wire connected to the node between an automotive brake light switch and the brake light. The luminous tube in the alarm device is arranged on an instrument panel in an operator cabin, and automatic detection to the operating condition of the brake light and alarm can be carried out. Thus, when the automobile runs, a driver can discover fault conditions of the brake light in time and repair the brake light in time, so that driving safety can be ensured.
Description
The utility model relates to a kind of automobile circuit accident warning device, specifically a kind of automobile brake lamp fault alarm.
Automobile in the process of moving, regular meeting can not pass to the vehicle that travels later with braking deceleration information exactly because of the brake lamp fault.For improving the safety of vehicle ', many automakers have installed the braking indicator lamp on gauge panel.But this indicator lamp can only show brake line and stop lamp switch well whether, can not the objective working condition that reflects brake lamp all sidedly, all can cause one or two brake lamies not work as faults such as brake lamp bad earth, bulb damage or line end open circuit, and in these cases, the braking indicator lamp is but glittering as usual, and this is with regard to the hidden danger of having buried for the rear-end collision accident.
The purpose of this utility model just provides a kind ofly can send the automobile brake lamp fault alarm of effective alarm message to the brake lamp fault, to reduce the accident potential that does not work and cause because of brake lamp to greatest extent.
The utility model is achieved in that the automobile brake lamp fault alarm is by two series resistance R
1, R
3With luminotron LED
1Compose in series resistance R
1Resistance much larger than with luminotron LED
1Adjacent resistance R
3Resistance.The both positive and negative polarity of the two ends tap automotive battery of this series arm is on the leaded node that is connected between automobile brake light switch and the brake lamp on the intermediate node of two resistance.
Because have two brake lamp parallel runnings at least on the general vehicle, therefore, this device should have at least two above-mentioned identical series arms to be in parallel, the brake lamp of lead-in wire tap in the middle of each series arm.
After installing this device additional, the luminotron in the annunciator is arranged on the gauge panel of operator's compartment, and the operating mode of brake lamp is detected automatically and reports to the police.In the vehicle ' process, the driver just can in time find the failure condition of brake lamp like this, maintenance in time, thus guarantee traffic safety, the rear-end collision accident of stopping to cause has thus been avoided the property damage and the personal casualty that cause thus.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the schematic circuit diagram after the utility model joins with automotive battery and brake lamp.
As shown in Figure 1, automotive battery E meets stop lamp switch K by wire fuse RX, and relay J is connected in series with K switch, its two open contact J
1, J
2Be serially connected in two brake lamp L respectively
1, L
2In the loop.Closed brake switch K, relay J gets electric adhesive, contact J
1, J
2Closure, brake lamp L

2All light.
This annunciator is the big frame of broken lines part on Fig. 1 top, wherein resistance R
1, R
3With LED
1Form first series arm, at R
1, R
3The intermediate node lead-in wire meets brake lamp L
1The positive terminal node.Resistance R
2, R
4With LED
2Form second series arm, at R
2, R
4The intermediate node lead-in wire meets brake lamp L
2The positive terminal node.Two-end-point branch after the two series arm parallel connections is connected to the both positive and negative polarity of Vehicular accumulator cell E.In this device, resistance R
1, R
2Select 10 kilo-ohms, 1/8 watt; Resistance R
3, R
4Select 1.2 kilo-ohms, 1/8 watt; LED
1, LED
2Select common light-emitting diode for use.
The principle of work of this annunciator is as follows: when brake lamp circuit and brake lamp all do not have fault, and two brake lamp L
1, L
2Respectively with R
3, LED
1And R
4, LED
2Be in parallel, because of R
1And R
2Resistance very big, and L
1, L
2Filament resistance only have several ohm, two light-emitting diodes that have been equivalent to short circuit.So almost there is not electric current to pass through LED on two light-emitting diodes
1And LED
2Their luminous voltage 1.75V of the voltage out of reach at two ends is not so luminotron is reported to the police.When meeting brake lamp L
1Or L
2Line broken circuit or filament when damaging, battery tension is through resistance R
1, R
3And LED
1(perhaps R

4And LED
2) form the loop, make LED
1Or LED
2Luminous warning reminds chaufeur in time to overhaul.
LED
1And LED
2Under non-damped condition, be warning indicator lamp, and when damped condition (being brake switch K closure), can light simultaneously with brake lamp.Therefore, this device also can play the effect of the parts service conditions such as insurance, stop lamp switch and relay in the auxiliary detection brake system simultaneously as the braking indicator lamp.
Claims (2)
