Abstract
The utility model relates to a fault alarm of a brake light for motor vehicles or automotive trains, which is composed of a coil 1, a dry or wet type reed pipe 6, a sound circuit 3 and an outer housing 7. The coil 1 winded on the reed pipe 6 is connected with the sound circuit 3 and is connected in series in the wires of a left and right brake light. When the fault of the brake light occurs, the normally-closed contacts 4 and 5 which are in the reed pipe 6 are closed and the sound circuit 3 is switched on to generate alarm signals; so the drivers in the cab can know the fault generates without observation.
Description
The utility model belongs to signals of vehicles equipment, the fault alarm device of the brake lamp of particularly a kind of self-propelled vehicle or motor-driven train.
The brake lamp of self-propelled vehicle or motor-driven train, its function be in time, rearwards vehicle sends wigwag exactly, to avoid hitting the tail accident.Constantly improve to allow under the situation that the speed of a motor vehicle rises day by day at category of highways, the effect of brake lamp is just more important.But as the motor vehicle driver that directly has influence on highway traffic safety, in general, themselves people may not know in the process of moving whether brake lamp is normal, and is all the more so when particularly driving full size vehicle or train-type vehicle.At present, have the high-grade luxurious minibus about 1% that the electronic type accident indicator is housed approximately abroad, show with indicator lamp on instrument carrier panel, but its price is higher, structure is also complicated.
The utility model is exactly to provide a kind of brake lamp fault simple in structure with low cost to report fast device for the defective that overcomes above-mentioned technology with regard to the purpose that is.
The utility model is to reach its technical purpose like this: with a coil 1 around do or wet type reed pipe 6 on, connect news and ring circuit 3 parallel seriess in the brake lamp circuit of the left and right sides, according to electromagnetic principle, when the magnetic force that coil produced is enough, normally closed contact 4 in the reed pipe and 5 disconnects, news ring circuit 3 do not work be left and right sides brake lamp just often, no alarm signal.In case the electric current of flowing through coil is zero or reduces promptly two brake lamies and do not work or have only one when bright, electromagnetic force is zero or reduce, and makes normally closed contact 4 and 5 closures, and news are rung circuit 3 and connected, and produce the alarm signal, and the driver need not watch and just know that fault produces.
This apparatus structure is simple, and reliable operation is made easily, and its cost only is equivalent to about 10% of external product, is very suitable for domestic and international any automobile or train-type vehicle and uses, and helps promoting highway traffic safety.
Fig. 1 is a structural representation of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing.
This device is by coil 1, do or wet type reed pipe 6, news ring circuit 3 and shell 7 is formed, wherein coil 1 is on reed pipe 6 and be connected to news and ring circuit 3, be connected in the brake lamp circuit of the left and right sides, normally closed contact 4 and 5 are arranged in the reed pipe 6, news are rung circuit 3 and are adopted suitable music IC, when the driver steps on brake pedal, as long as not hearing news rings, brake lamp is exactly normal, otherwise, must have at least a brake lamp that fault is arranged, in order to keep away that face can not in time be eliminated fault (as there not being replacing bulb on the way) because of the limitation of conditions and the each glancing impact that causes sends news and rings, ring in the circuit 3 in news also to be provided with a switch 2.
Claims (1)
1, a kind of brake lamp fault is reported fast device, it is characterized in that it is by coil (1), dried or wet type reed pipe (6), news ring circuit (3) and shell (7) is formed, wherein coil (1) is connected in the brake lamp circuit of the left and right sides on reed pipe (6), normally closed contact (4) and (5) are arranged in the reed pipe (6), and being connected to news sound circuit (3), news are rung circuit (3) and are adopted music-integrating block, also are provided with a switch (2) and ground connection in the news sound circuits (3).
