Automobile rear-end collision prevention device

Abstract

The invention relates to an automobile rear-end collision prevention device which includes a casing and a panel arranged at the front end of the casing. A strip-shaped display panel is embedded in thepanel, and the long side of the display panel is horizontal. A strip-shaped light incident hole is formed in the lower portion of the display panel, and the long side of the light incident hole is parallel to the long side of the display panel; and a reflective sheet and an imaging lens are fixedly arranged in the casing. The imaging lens is formed by splicing horizontal strip-shaped lenses in the vertical direction, and the colors of the strip-shaped lenses are different. Light entering from the light incident hole sequentially passes through the reflective sheet and the imaging lens and then irradiates the display panel. The device can intuitively remind a rear vehicle driver of the vehicle distance to provide more accurate information for the rear vehicle driver's emergency response and effectively reduce the probability of a traffic accident caused by visual defects.

Description

technical field [0001] The invention relates to an automobile accessory, in particular to an anti-rear collision 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 small, ...

[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
