What is the use of vertical lines on car mirrors?

In fact, the rearview mirror with its own dotted line is called"Double curvature mirrors"Due to the limitation of the size of the rearview mirror, how to let the owner see more and clearer range from the rearview mirror is what many car owners pay attention to. This dotted line is distributed on the outside of the force, usually a third, and we call the part outside the dotted line the outside of the mirror. The outside is a convex mirror, and because of the small radius of curvature, we can see farther from the outside, which is useful at high speeds, and also helps to eliminate driving blind spots when cornering, so that we can anticipate the situation behind us and take appropriate measures.

On the inside of the dotted line, it is a normal field of view used to observe the near situation, because of the large curvature, we can see the near situation very clearly, for example, when reversing, we can clearly see the position of the rear wheel and the car next to it. In normal use, because of the combination of two different curvatures, we can take into account the near and far field of vision, effectively reduce the blind spot of the rearview mirror, easy to use, and reduce the danger. This design is similar to the small round mirror we have installed in the rearview mirror.

This is a double curvature rearview mirror, the mirror outside the dotted line can see a wider range, especially in high-speed driving, the dotted line within the observation of the body range is larger, it is easier to judge the position of the body when driving at low speed, the combination of the two reduces the blind spot of the rear line of sight, and improves driving safety!

Double curvature rearview mirror, line is an ordinary small field of view rearview mirror, small deformation; Beyond the line is a large-field rearview mirror with a wide range but large deformation.

The vertical line on the rearview mirror of a car is the dividing line that distinguishes the mirror surface. Known as the "double curvature mirror shed", it is used to observe the closer position of the side of the body, and the combination of the two curvatures can minimize the blind spot of the rearview mirror. More details are as follows:

First, the rearview mirror of the car is the driver's "second eye", its basic function is to expand the driver's field of vision, reduce blind spots, and increase the safety of driving. When driving, turning, getting out of the car and reversing, you have to look carefully at the rearview mirror, and do not look at the rearview mirror, which is quite dangerous driving behavior. Second, the role of the vertical line on the rearview mirror of the car:

1. First of all, there is this line because this rearview mirror uses a double curvature lens, which is also a lens with 2 kinds of curvature, according to the model, the driver's eyepoint position and the relative position of the rearview mirror, and the three elements of vision requirements, using optical principles and data methods, the different curvature radius of the vehicle's front and rear left and right different vision angles, and smooth transition, the inside of the rearview mirror, that is, the 2U002F3 lens close to the cab adopts a normal plane mirror, and the 1U002F3 lens on the outside adopts a convex mirror, In the middle, there is a black line separating the driver to better see what is going on. 2. The dotted line is used to observe the ordinary field of view of the near situation, due to the large curvature, you can see the near situation very clearly, such as when reversing, you can see the position of the rear wheel and the car next to it. In ordinary use, because of the combination of two different curvatures, it can take into account the near and far field of vision, effectively reduce the blind spot of the rearview mirror, facilitate use, and reduce the danger.

This design has a similar effect to the small round mirror mounted on the rearview mirror.

This is a double curvature rearview mirror.

Advantages: normal curvature on the medial, small deformation, large curvature on the outside, enlarged visual field, mainly enlarged left and right visual fields. Cons:

There is a difference between the inside and the outside, so some people will feel dizzy. And the field of view has also expanded. The radius of curvature outside the dotted line is smaller, mainly used to observe the situation of the farther position on the side of the body, within the dotted line, the radius of curvature is larger, and it is used to observe the situation of the closer position of the side of the body, and the combination of the two curvatures can minimize the blind spot of the rearview mirror.

This is a double curvature rearview mirror, the mirror outside the dotted line can see a wider range, especially in high-speed driving, the dotted line within the observation of the body range is larger, it is easier to judge the position of the body when driving at low speed, the combination of the two reduces the blind spot of the rear line of sight, and improves driving safety!

Rearview mirrors with this thin line are called "double curvature rearview mirrors". The mirror is divided by a thin line, in which the larger area is the conventional curvature, you can observe the area behind the vehicle and the small side of the rear, the smaller area of the curvature is larger than the conventional, you can see the wider position of the side of the body, that is, reduce the rearview mirror angle dead zone, so that the driver has a wider angle of view when changing lanes or overtaking. It is used to see the blind spot in the back, and in layman's terms, the diopters of these two mirrors are different.

This eliminates the need to have a small mirror on top like any other car.

I think it's the selling point of the making, and it's almost the same.

This should be a positioning system through which you can see where your car is when reversing.

The vertical line on the rearview mirror is convenient for the driver to determine whether the car is correct or not.

This serves as a positioning point, so it will be more convenient for you to reverse.

This rearview mirror is called a double curvature rearview mirror, which is actually for the aspect we see.

I think the vertical line tells you if the car behind you is directly behind you.

This vertical bar may be designed to give people who drive a better standard of parking.

It may be a marker that is used to reverse or drive.

This is because it is designed to work better.

In order to reverse more safely, otherwise it would not have been designed like this.

The purpose of this vertical bar is to clarify your vision and let you see more clearly.
