Automobile rear-end collision warning device

Abstract

The invention relates to an anti-rear-collision reminder device for automobiles. The anti-rear-end collision reminder device for automobiles includes a base, the base is installed at the rear of the automobile, and a prompting board is arranged on the base, and the prompting board extends from the center of the base to Arranged on the left and right sides; each of the prompting boards is covered with a light guide cover to limit the viewing angle of the prompting board. The center of the seat, the smaller the inclination angle of the center line of each viewing angle; the device can visualize the distance between the front and rear vehicles, provide timely and accurate distance information for the driver of the rear vehicle, shorten the emergency response time of the driver, and effectively reduce rear-end collision accidents to ensure the safety of drivers and maintain the smoothness of road traffic.

Description

technical field [0001] The invention relates to an auto accessory, in particular to an anti-rear-collision reminding device. Background technique [0002] With the popularization of automobiles, automobile traffic accidents are also gradually increasing, especially on expressways, where automobiles are traveling at a faster speed, and chain collisions are likely to occur when traffic accidents occur, causing serious casualties and causing traffic jams. Seriously affect the passage of passing vehicles and cause great pressure on traffic. High-speed traffic accidents can be described as a serious disease of the traffic network; one of the reasons for high-speed traffic accidents: the vehicle in front decelerates, which is not obvious from the rear, causing the reaction time of the driver behind Extended, and when the rear vehicle finds the situation, it may be too late to brake to avoid danger; the reason is that the size of the front vehicle observed by the rear driver is sma...

[0002] With the popularization of automobiles, automobile traffic accidents are also gradually increasing, especially on expressways, where automobiles are traveling at a faster speed, and chain collisions are likely to occur when traffic accidents occur, causing serious casualties and causing traffic jams. Seriously affect the passage of passing vehicles and cause great pressure on traffic. High-speed traffic accidents can be described as a serious disease of the traffic network; one of the reasons for high-speed traffic accidents: the vehicle in front decelerates, which is not obvious from the rear, resulting in the reaction time of the driver behind Extended, and when the rear vehicle finds the situation, it may be too late to brake to avoid danger; the reason is that the size of the front vehicle observed by the rear driver is small, and as the distance gets closer, the vehicle model gradually becomes larger; when the two vehicles are far apart , the size of the car model is not obvious when the distance is shortened, but when the distance between the cars is very close, the car model will change obviously, and at this time the driver behind can feel it sensitively; under this visual defect, the reaction is not The driver of the rear vehicle in time is very likely to collide with the vehicle in front, causing safety accidents; especially at night or in foggy weather, the line of sight is severely disturbed, and the driver's reaction time in an emergency is prolonged, which is more likely to cause a car accident
