Abstract
The utility model discloses a monitor of vehicle signal lights, and the monitor in the state of the indicator lamp of the instrument panel of the vehicle can synchronously monitor the operation state of external signal lamps. The utility model comprises silicon rectifier diodes D1 and D2 and an electro-optic coupling device T1. The on-off state of the external signal lamp (1) of the vehicle makes use of the control pressure drop in the silicon rectifier diodes D1 and D2 connected with the circuit of the indicator lamp in series; thus the output ends (7, 8) of the electro-optic coupling device T1 are connected or cut off so that the indicator lamp of the instrument panel is connected or cut off.
Description
The utility model relates to a kind of device of synchronous identification signals of vehicles lamp failure.Belong to the car electrics technical field.
Generally, signal lamps (hereinafter to be referred as " outer lamp ") such as direction display lamp and brake taillight all are housed in the outside of power actuated vehicle, on the indoor gauge panel of vehicular drive, then have corresponding indicator lamp (hereinafter to be referred as " interior lamp ") with outside lamp be connected.Up to the present, the circuit between them is connected in parallel, so, in the way of travelling, in case have one or several lamp to hinder for some reason in the outer lamp that is using and damage, and on the gauge panel corresponding in lamp can not extinguish synchronously.Chaufeur is as can not in time realizing the failure condition of outer lamp, and vehicle will be driven against traffic regulations, and traffic accident takes place easily.
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of device that can discern the signals of vehicles lamp failure synchronously is provided, it can do synchronous supervisory demonstration on the lamp with the operation conditions of the indicator of outside vehicle, lampet, stoplight stop lamp etc. in gauge panel corresponding, with the support vehicles safety traffic.
Task of the present utility model is finished by following measures; Two silicon rectifier diodes of serial connection in outside vehicle signal lamp circuit, at the input end of the two ends of these two a silicon rectifier diodes photoelectric coupled device in parallel, the output two ends of this photoelectric coupled device then are serially connected in the circuit of gauge panel indicator lamp.When the outward sign lamp is in running state, just there is electric current to flow through and is serially connected in the interior silicon rectifier diode of its circuit, the pressure drop voltage that produces at the rectifier diode two ends is input to photoelectric coupled device, light the light-emitting diode in the photoelectric coupled device, and make the output two ends conducting of photoelectric coupled device, thereby connect corresponding indicator lamp line power on the gauge panel and in making lamp glittering.Otherwise if outer lamp hinders for some reason and damages, no current passes through in the circuit, does not then have pressure drop on Chuan Jie the rectifier diode, not conducting of photoelectric coupled device, and corresponding interior lamp driver no current is so interior lamp is not glittering yet.Like this, chaufeur in the car on the gauge panel situation of indicator lamp just can correctly know the real time execution situation of outside vehicle signal lamp, thereby guaranteed safe driving.
Circuit of the present utility model is simple, and whole device adopts the Highgrade integration modular designs, have volume little, easy-to-connect, long, low price of life-span be installed, and advantage such as self not power consumption is an important device that improves present vehicle safety train operation performance.
Fig. 1 is schematic circuit diagram of the present utility model.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
In schematic circuit diagram shown in Figure 1, the major part of the supervisory device 11 of the utility model signalling light for vehicle has silicon rectifier diode D

2Two ends 3,4 produce tube voltage drop voltage, and this voltage is input to photoelectric coupled device T
1, light light-emitting diode 14 wherein, and make photoelectric coupled device T
1Output two ends 7,8 between conducting, thereby connect the line power of corresponding indicator lamp 12 on the gauge panel and make indicator lamp 12 glittering.If damage falls in signal lamp 1 for some reason, then no current passes through the rectifier diode D of serial connection in its circuit
1, D
2Last no pressure drop, photoelectric coupled device T
1Not conducting, corresponding indicator lamp 12 circuit no currents are so indicator lamp 12 extinguishes.
The utility model is applicable to a plurality of signalling light for vehicles.Embodiment illustrated in fig. 1 just having drawn is used for the supervisory device electrical schematic diagram of two signal lamps.The utility model is also applicable on the automotives such as aircraft, boats and ships.
The utility model is designed to the module drive formula, operating voltage range+5V～+ 25V, electric current 20mA, ambient temperature-15 ℃～+ 100 ℃.
