Abstract

A double rear-end collision prevention device comprises a radar ranging sensor, warning lamps and a control box, and is characterized in that the warning lamps are mounted around a license plate (1) at the rear end of a vehicle, the radar ranging sensor (3) is mounted below the license plate, a red LED vehicle speed display screen (4) is mounted on a rear window, the control box (5) is mounted in a bridge, and a circuit board (6) is mounted in the control box. The double rear-end collision prevention device overcomes the shortcomings of the existing rear-end collision prevention device, and has the advantages of simplicity in production process, evident effect in rear-end collision prevention and the like.

Description

The dual anti-device that knocks into the back

Technical field

The utility model relates to the safety traffic field, a kind of more precisely anti-device that knocks into the back of radar velocity measurement that utilizes.

Background technology

Automobile, oneself becomes the indispensable vehicle in people's life at present, with the increase day by day of work automobile amount; Make road become more and more crowded; Spacing on the road is separated by also shorter and shorter, causes rear-end collision to take place often, threatens people's safety of life and property.The reason that rear-end collision takes place is the travel conditions that the chaufeur of at the heel vehicle can't accurately be understood front truck, and all are in passive position, and front truck slows down and just and then slows down, just and then brake after the front truck brake, and back car is slower than front truck all the time.Another reason, along with the fast development of express highway, automobile driving speed is very fast; In case front truck generation emergency situation sudden stop, because braking distance is longer, and the restriction of people's speed of response; Rear-end collision also takes place easily, and the impulsive force between the automobile being bigger, usually is car crash; And causing the accident that shunts into one another, one on follow-up vehicle connects a ground and hits together, causes huge personal casualty and economic loss.

Summary of the invention

The purpose of the utility model is to overcome above-mentioned deficiency, provides easy, the anti-obvious results that knocks into the back of a kind of production technology the dual anti-device that knocks into the back.

The purpose of the utility model adopts following technical measures to realize: a kind of dual anti-device that knocks into the back, form by radar ranging sensor, Warning light, control capsule, and it is characterized in that: Warning light is housed around the vehicle tail end car plate; Said Warning light is: the high brightness red LED; The radar ranging sensor is housed under the car plate, red LED speed of a motor vehicle read-out is housed on the vehicle rear window, control capsule is housed in the operator platform; Radar ranging sensor interface, high brightness red LED interface are housed on the box face; Circuit card is housed in the control capsule, amplifying circuit, driving circuit, central process unit is housed, change-over circuit on the plate.

The remarkable result of the utility model:, let the back car in time understand the front truck vehicle speed condition, when throttle reduces owing to adopt red speed of a motor vehicle read-out; The high brightness red LED is bright, and when decontroling Das Gaspedal, the high brightness red LED is flashed; When stepping on down brake, the high brightness red LED is flashed fast, can produce visual stimulus to back car chaufeur; Effect is remarkable, and production technology is easy.
