A small ring (4) is arranged on the lower part of the brand, for detecting the positive end of an electrode. Two holes are arranged on the surface of the brand, for detecting the negative end of the electrode. One hole (1) is used as a display hole of the high-voltage circuit, and the other hole (2) is used as the display hole of the low-voltage circuit. A high-voltage detection circuit, a low-voltage detection circuit and an illumination circuit are composed of a high-voltage induction luminous element, a luminous element, a voltage stabilization element, and a rectifying element. The utility model can be used as a key brand or a pen in normal times. When the motor-driven vehicle generates malfunction, the utility model can be used as a circuit detection device. The utility model has the advantages of complete function, simple operation, and convenient operation. The utility model is an ideal electric appliance of the motor-driven vehicle.
Description
The utility model relates to the safety detection of motor vehicles, is particularly useful for the fault detect of various motor vehicles high-tension circuits, low-voltage circuit, light indicating circuit.
At present, along with developing rapidly of communication, the quantity of various motor vehicles with day increase severely, because of the tape jam driving, cause that traffic hazard is also corresponding to be increased, bring about great losses for people's life and national wealth.In order to reduce the generation of traffic hazard, a lot of dissimilar vehicle safety attention device and trouble shooting instruments have now been worked out, Chinese patent 90213574.0, name is called ' multi-purpose vehicle(MPV) safety is exercised warning device ', it can be for automobile provides the signal that knocks into the back and overtake other vehicles, but does not relate to the detection of vehicle fault.
The purpose of this utility model is a kind of fault detect instrument of searching various motor vehicles high-tension circuits, low-voltage circuit, light indicating circuit fast and accurately of design.Avoid searching the fault difficulty, and the tape jam driving causes traffic hazard because of lacking the fault detector.
Technical solution of the present utility model is; The appearance of this motor vehicle safety detecting device can be made into circle, square, polygonal swatch, one little ring (3) is arranged on the top of board, be the detecting electrode anode, one little ring (4) is arranged at the bottom, be the detecting electrode negative terminal, two holes are arranged on the surface of board, and hole (1) is the high-tension circuit display aperture, and hole (2) are the low-voltage circuit display aperture.The internal circuit of this motor vehicle safety detecting device is by telefault L and high voltage induction light-emitting component D
4Form high-voltage detecting circuit, by light-emitting component D
1, voltage stabilizing element D
2, rectifier cell D
3Form low-voltage testing circuit and lighting circuit.
The high-voltage detecting circuit part mainly is to adopt high voltage induction light-emitting component D
4The external form of this fault detector can be the key card or the pen of multiple shape, when fault appears in motor vehicle, can be used to the detection circuitry fault.
Fig. 1 is a synoptic diagram of the present utility model.

Be described further below in conjunction with accompanying drawing:
Circuit part of the present utility model is by telefault L and high voltage induction light-emitting component D
4Form high-voltage detecting circuit, high voltage induction coil L one end is connected with needs testing circuit output terminal, and the other end is with high voltage induction light-emitting component D
4Connect.When motor vehicles can't start need inspection high-tension circuit, can be with the ring (3) of safety detector, (detecting electrode anode) close hi-line or high-tension coil, starting engine, high voltage induction light-emitting component D at this moment
4Glittering, prove high-tension electricity, if high voltage induction light-emitting component D
4Not glittering, prove that high-voltage circuit system has fault.
By light-emitting component D
1, voltage stabilizing element D
2, rectifier cell D
3Form low-voltage testing circuit and lighting circuit.Light-emitting component D
1Negative pole is connected with the output stage of institute's slowdown monitoring circuit, light-emitting component D
1Positive pole and voltage stabilizing element D
2, rectifier cell D
3Negative pole connects, rectifier cell D
3Positive terminal is connected with the circuit output cathode of being surveyed with telefault L.When need detect various lamp wirings or low-voltage circuit, an end that detecting device is indicated (-) utmost point is with lead or directly connect with car body, connect at the circuit of an end that detecting device is indicated (+) utmost point with required detection, if circuit is normal, detecting device low pressure indicator lamp hole (2) is bright, if there is not voltage to pass through measurement point, detecting device low pressure indicator lamp hole (2) does not work, detect by the said method segmentation, can measure the guilty culprit position.
Whether whether detect vehicle battery and contact well, (+), (-) of vehicle battery extremely extremely directly can be connected with (+), (-) of detecting device, it is good to measure contact.
When night, maintenance vehicle need throw light on, (+), (-) utmost point of detecting device can be connected with (+), (-) utmost point of accumulator, can do illumination and use.
This safety detector can detect all circuit of motor vehicles, and the driver is flexible Application according to circumstances.
External form of the present utility model can be designed to the key card shape or the lip pencil of multiple shape, can be printed on various patterns and literal on the board, can make key card or pen at ordinary times, when motor vehicles break down, can make circuit detector.This product function is complete, and is simple to operate, easy to use, is the desirable fault detecting instruments of motor vehicles.
