Abstract

The invention discloses an early warning device capable of preventing automobile rear-end collision. The device is formed by connecting an automobile brake pedal, a variable resistor, a continuous flicker controller and an automobile tail light. The brightness and even flicker change of the automobile tail light are controlled according to the treading degree of the automobile brake pedal, namely the automobile brake deceleration degree so that after prompt and early warning, the driver brakes or brakes emergently to avoid the automobile rear-end collision traffic accident happening when the driver does not brake in time or brake emergently, thereby saving the life safety and property safety of the people.

Description

The anti-brake prewarning device that knocks into the back

Affiliated technical field

The present invention makes and reduces the probability that knocks into the back through the automobile tail light variation through between braking automobile pedal and taillight, increasing electric device.

Technical background

At present the relation between braking automobile pedal and the automobile tail light is braking automobile pedal when trampling down, and automobile tail light will light to point out the back car driver that goes.And the degree that brake pedal is trampled can't show through automobile tail light; And cause back car driver to have no idea very first time judgement front truck with which kind of intensity brake; Make the back car often because of there not being timely sudden stop to cause knocking into the back; Particularly on the expressway, understand therefore occurrence of traffic accident, seriously then car crash with the traffic congestion location.The present invention is through increasing resistance between brake pedal and automobile tail light, and flash controller continuously, when making the vehicle traveling process brake, can give the prompting of back car brake driver degree, to guarantee back car sudden stop and avoid occurrence of traffic accident in time.

And the electric device that in this device, increases is a variable resistance and a controller, is dirt cheap, and can make this device be applied to all vehicles fully.

Summary of the invention

In device, the braking automobile plate is trampled degree decision brake degree, the just degree of deceleration/decel.With increasing a variable resistance between braking automobile plate and the automobile tail light; Brake process connects automobile tail light through variable resistance; And make automobile tail light step on to such an extent that the degree difference has the different variation of light and shade because of brake institute, point out back car driver to follow thus and brake and can not knock into the back with which kind of degree.Be in the pedal position of sudden stop again at automobile, increase continuous flash controller, when making vehicle be in sudden stop, this tail-light continuously flicker comes car driver emergency brake after the early warning, avoids because of failing the traffic accident that timely sudden stop causes.

The beneficial effect of this device is through adding cheap simple forewarn system, to prevent the driver because of the rear-end collision untimely or that the brake degree causes inadequately of braking.

Below in conjunction with accompanying drawing and embodiment this device is further specified.

Fig. 1 is this device schematic circuit diagram that do not touch on the brake.

Fig. 2 is this device schematic circuit diagram that gently touch on the brake.

Fig. 3 is this device sudden stop schematic circuit diagram.

Among the figure, 1 vehicle power, 2 brake pedal plate contact disks, 3 variable resistances, 4 contact disks, 5 continuous flash controllers, 6 automobile tail light.

In Fig. 1, when vehicle traveling process did not touch on the brake, automobile tail light and vehicle power did not have UNICOM and do not work.

In Fig. 2; Automobile is because of the needs process that gently touches on the brake; Brake pedal contact disk (2) slides (3) on variable resistance, makes automobile tail light (6) that the variation of light and shade take place because of resistance variations, points out back car driver to change the brake degree that changes oneself according to taillight thus.

In Fig. 3; When the driving vehicle braking state is the sudden stop degree; The contact disk (4) of brake pedal contact disk (2) and continuous flash controller (5) is when contacting; Automobile tail light (6) receive continuous flash controller control (5) and the rapid Continuous flicker, and car driver emergency brake at once after pointing out is thus avoided knocking into the back.

Claims

1. a braking automobile prior-warning device is connected to form by braking automobile pedal, variable resistance, continuous flash controller, taillight.

2. braking automobile prior-warning device according to claim 1; It is characterized in that: major part connects to form for the variable resistance and the continuous flash controller of cheapness; Function is related with the light and shade and the flicker realization of automobile tail light for realizing the brake degree, to reach the effect of early warning brake degree.

3. braking automobile prior-warning device according to claim 1 itself be easy to realization property, material cheapness property, and realize the anti-effect characteristic that knocks into the back.
