Automobile rear-end collision prevention reminding device

Abstract

The invention relates to an automobile rear-end collision prevention reminding device. The automobile rear-end collision prevention reminding device comprises a base installed on the tail portion of an automobile and provided with prompt boards. The prompt boards are arranged towards the left side and the right side from the center of the base. All the prompt boards are covered with a light guidecovers used for limiting the visible angles of the prompt boards. The median of the visible angle of each light guide cover inclines to the center of the base. The closer to the center of the base thelight guide covers are, the smaller the inclination angles of the medians of the visible angles are. The front and rear vehicle distances can be displayed through the device, accurate vehicle distance information is supplied to a rear vehicle owner in time, the emergency response time of the driver is shortened, rear-end collision accidents are effectively reduced, the life safety of the driver is guaranteed, and road traffic smoothness is maintained.

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
