Method for solving line of sight of blind zone at rear side of carrier and expanding line of sight of width and rear view mirror thereof

Abstract

The invention discloses a method for solving the line of sight of a blind zone at the rear side of a carrier and expanding the line of sight of width. A rear view mirror used by the carrier is longitudinally divided into at least two curved visual zones, wherein the two curved visual zones respectively include a backward-inclined curved tail visual zone and a curved front visual zone; the reflected light of the curved tail visual zone and the reflected light of the curved front visual zone form crossed lines of sight; the curved front visual zone is used for observation of normal running, side faces of the carrier as well as running of the changed side; and the curved tail visual zone is used for expanding observation of the carrier out of the line of sight, normal running as well as running of the changed side. The method can keep original fidelity and simultaneously can outward increase 0.5-2 times of transverse sight distance, thereby reducing the accident rate and improving the driving safety.

Description

technical field [0001] The invention relates to a vehicle rearview mirror, in particular to a method for solving the sight line in the rear blind area of ​​the vehicle, expanding the width of the line of sight and the rearview lens thereof. Background technique [0002] 1. According to reports, about 30% of the traffic accidents in my country are caused by the blind area of ​​the rearview mirror of the transportation vehicle, especially because the left or right turn signal is turned on when driving, and the left or right rearview mirror is checked. After confirming that there is no car, they are ready to turn the steering wheel When merging or exiting a roundabout, a car suddenly emerges from the left or right side of the car. This is not because the adjustment of the rearview mirror is not in place, but because the horizontal viewing area of ​​the rearview mirror of the vehicle behind is too small; The mirrors are all adjusted in place, but why is scratching inevitable?

[0002] 1. According to reports, about 30% of the traffic accidents in my country are caused by the blind area of ​​the rearview mirror of the transportation vehicle, especially because the left or right turn signal is turned on when driving, and the left or right rearview mirror is checked. After confirming that there is no car, they are ready to turn the steering wheel When merging or exiting a roundabout, a car suddenly emerges from the left or right side of the car. This is not because the adjustment of the rearview mirror is not in place, but because the horizontal viewing area of ​​the rearview mirror of the vehicle behind is too small; The mirrors are all adjusted in place, but why is scratching inevitable? This is related to the blind spot of the rearview mirror. According to the data, when a normal driver only turns his eyeballs and does not look back, although people can see the range of about 200 degrees in front, it is actually effective, direct and clear with a single vision. In the range of 90 degrees to 140 degrees, when the vehicle is moving forward and backward, the existing left and right rearview mirrors plus the central rearview mirror on the market can only provide an additional viewing range of about 60 degrees. The 160-degree angle is the blind spot. Some car owners put a small convex mirror on the rearview mirror, which can indeed further eliminate some dead spots, but the wider the viewing angle of the rearview mirror, the greater the degree of image distortion. , and the distance from the object in the mirror is more difficult to grasp

2. When we were about to merge into the main lane to the left at the meeting intersection, when we first arrived at the meeting intersection, the left rearview mirror of the old-fashioned vehicle could not see the left side because the body of the vehicle had not yet formed the same straight line with the main lane. For the road conditions close to the first lane on the side, the driver can only turn his head to the left to observe whether there is a car outside the window or on the rear side. However, some drivers forget to observe or fail to take into account the driving of the vehicle in front, causing traffic accidents

3. When the vehicle is turning, the rearview mirror on the side that is turned or turned around has a smaller view of the road. Usually, only the side of the vehicle body and the rear perpendicular to the vehicle body can be seen, and the road surface of the other lane cannot be seen, so it is easy to cause traffic accident
