Description

The anti-warning Der Blink und Abblendschalter that knocks into the back of self-propelled vehicle

The utility model relates to a kind of signals of vehicles device, is that a kind of self-propelled vehicle that is used for prevents to knock into the back and the device of the warning signal that flashes when driving or parking particularly.

The anti-warning device that knocks into the back of existing self-propelled vehicle mainly contains two kinds of flash light and caution notice boards.Its a kind of warning flash light of forming by power supply connection oscillator, relay and bulb load, but this kind flash light is many as open power consumption in driving always, wastes energy; When especially night, car stopped the roadside,, easily cause discharged or defective battery even damage, and if close lamp, can cause rear-end collision again, its complex operation, use inconvenience if the long period turns on light.It two is the triangle caution notice boards that are printed on alert exclamation sign, but the board body is big, dress is hung inconvenience, especially night visiblity low, can not give full play to warning function.

The purpose of the utility model provides the anti-warning device that knocks into the back of a kind of later-model self-propelled vehicle, makes its novel structure, expends lowly, equipped simple and easy, easy to use, and can prevent the locomotive rear-end collision effectively.

For achieving the above object, the solution of the utility model employing is: will be connected by the opto-electronic conversion control circuit that electro-optical tubes, monostable photoswitch circuit and stable multi-oscillation circuit are formed and make circuit card, circuit

The plate load consists of photoelectric conversion controller in the boxlike body.Three outer clearance lines of circuit card connect car light, bonding ground connection respectively and are connected power sources of motor vehicle by manual switch, consist of light-operated automatic caution flasher.And can print warning mark at the controller external surface.During use, photoelectric conversion controller is loaded on motor vehicle rear, behind the light-illuminating of the back self-propelled vehicle electro-optical tubes to the light-controller, light-controller through opto-electronic conversion, amplification and vibration, makes the flash of light of bonded assembly car light send alarm signal optical signal.

Because the utility model has adopted light-operated automatic caution flashing feature, visible light by the rear portion vehicle is controlled, and installed manual source switch additional, its novel structure, little power consumption, install simple, easy to use, no matter driving a vehicle or stop on night all can prevent rear-end collision effectively, is a kind of later-model self-propelled vehicle anti-rear end collision safety alarming device.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is a basic circuit of the present utility model.
