Why is there a dotted line on the car mirror?

Because this dotted line is designed to play a supporting role. When the driver reverses into the garage, if the garage door is located on the left side of the dotted line, it means that reversing is normal; However, if the garage door is on the right side of the dotted line, it means that the car is reversing incorrectly and the car is likely to be scratched. So this dotted line is very useful and can be used to alert the driver.

Although many people have already obtained a driver's license, there are still many novice drivers who have little knowledge about the vehicle. Different car configurations and driving skills will also be different, and now there are many types of cars, and the brands are also various, so it is best to understand the relevant configuration and driving skills of the car before driving, and the rearview mirror is an eye behind the driver, so that the driver can understand the situation behind the car. <>

When we are reversing, the rearview mirror can assist the driver to reverse accurately. At this time, the dotted line on the rearview mirror plays a very important role to remind the driver of the specific situation of reversing. The dotted line divides the rearview mirror into two parts, one of which is a convex mirror and the other is a flat mirror.

Therefore, the rearview mirror with a dotted line will have a wider line of sight, and the blind spot of the field of vision will be smaller, and even novices can accurately reverse into the garage.

In addition to assisting the driver to quickly reverse into the garage, this kind of mirrors with dotted lines can also be very helpful when driving at high speeds and cornering. Because it widens the driver's line of sight, the driver can see clearly around the vehicle in advance in such situations and react accordingly.

This dotted line on the rearview mirror of a car is the dividing line that distinguishes the area of the mirror with different curvatures, and the scientific name of this line is "double curvature rearview mirror". On the inside of the dotted line, that is, on the side close to the body, this area is the ordinary rearview mirror, but on the outside of the dotted line, this area is equivalent to a convex mirror, and the range of vision in this area is wider.

There is a dotted line in the middle of the car rearview mirror, which divides the mirror into two, which is actually used to remind you, if you can see the rear car appear in the right plate, it means that the car behind you is still far away from you, if it is on the left, it means that it is close.

Because the reflective area rate of the mirror surface is different, the large area inside the dashed line is the normal curvature, and the deformation of the reflected field is small, and the small area outside the dashed line is large curvature, and the deformation of the reflected field is larger, so a larger observation range can be obtained.

Because the refractive index of the left and right mirrors of this dotted line is different, for the driver to drive better.

If there is a dotted line on the mirror, it means that it is a double-curvature mirror, which can reduce the blind zone. Most bicurvature mirrors basically have an anti-glare function. Rearview mirrors are very important for drivers.

Basically look in the rearview mirror when you're turning and changing lanes, and also when you're reversing. Make sure your mirrors are at the correct angle while driving, otherwise it will affect your safety and vision.

<> many cars have electric mirror adjustment, which is standard in almost every car. The occupant can adjust the angle of the mirror via the mirror adjustment button. On this point, I specially consulted some of my friends Ye Grip, according to which he explained that such a curve is indeed very practical, and there must be a very friend who is puzzled at this time, so what is the magic of this dotted line?

In fact, this curve represents a special kind of rearview mirror, this rearview mirror is composed of two parts, one is a flat mirror, the other is a concave mirror, and the dotted line is their incision, so this is not the dotted line of all mirrors. There is also the appearance of rearview mirrors with concave mirrors or convex mirrors, mainly because the convex mirror can expand our field of vision and show the road conditions behind us more clearly on the rearview mirror, reducing our visual blind spots. It's worth taking the time to learn and explore, and if you guys have any ideas, you can let us know in the comments below.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you think what we all think, you leave a message below the article to express your opinion.

It is the dividing line between the convex mirror and the plane mirror of Lixiang jujube. The 1 3 of the mirror is a convex mirror, or close to the outside. The limb dismantling 2 3 near the inside of the car are all plane mirrors. This is to improve the driver's field of vision.

The function is to reduce the driver's blind spot, and it is also to protect the driver's life safety, and to prevent the car from colliding, so I think this dotted line is very important for the car.

The mirrors with dotted lines are double-curvature mirrors, which can better reduce blind spots, and this kind of mirrors have anti-glare function.

I don't know if you have ever seen the rearview mirror of the car, there will be a dotted line on it, which is a sign of the hyperbolic potato residue rate rearview mirror. Because this dotted line is mainly in the position of the entire mirror 1 3, it can help the owner to see clearly a situation of the surrounding vehicles, so it can reduce the occurrence of some traffic accidents. <>

First, because it can effectively see the situation of the vehicle, the occurrence of traffic accidents is reduced

In fact, many car owners have not seen their rearview mirrors, because under the effect of strong light, this dotted line will fade, and even some car owners' eyesight is not very good, so they will ignore this dotted line, in fact, the importance of this void is still great. Because there are more vehicles now, there are more styles, so there are more types of design of rearview mirrors, ordinary rearview mirrors are plane mirrors, which can effectively see the situation behind clearly, but with the increase of vehicle performance, then the original plane mirror becomes a double-curvature rear-view mirror, so that the rear-view mirror has a certain arc, and can effectively see a traffic flow around their vehicles. <>

Second, the dotted rearview mirror is safer and better

Compared with the general rearview mirror, this kind of rearview mirror has a wider range, so it can effectively reduce the occurrence of accidents, and at the same time, it can also make the owner drive more safely. Although this kind of rearview mirror is very good, some car owners feel uncomfortable when using it, so they will still change back to their original flat mirror. But for the sake of your own life and health, try to use the double-curvature rearview mirror, because driving is still a relatively unsafe thing after all, so you must be equipped with a safe vehicle.

III. Conclusion

In addition, I would like to appeal to all car owners, go back to check whether there is a dotted line in the rearview mirror of their vehicle, if there is no dotted line, then be more careful in the process of driving. If you don't have a car at home and are ready to buy a car, then you should buy a vehicle with a dotted line, which will be safer and more reassuring to drive.

Through the rearview mirror, you can Kaihulu to understand the panoramic view behind the car, and then you can also observe the position of the body to stare at the distance, so that you can eliminate the blind spot when turning, and then you can also expand the line of sight to twice as much as before, the position within the dotted line, the radius of curvature is very large, so the angle of observation is very wide, which can reduce the blind spot and reduce the risk.

The dotted line inside the rearview mirror is to effectively improve the rear vision, it is a kind of double-curvature rearview mirror, so as to effectively improve our driving safety.

Because this can be a good analysis of the rear field of vision, it is conducive to understanding the problem of car distance, and the addition of dotted lines is more practical.

1. The rearview mirror with the dotted line has a unified name called the double curvature rearview mirror, you can observe it, generally speaking, the virtual Tantan Na line part is the 1 3 of the entire rearview mirror, which is the outer viewing angle part, and the dotted line is the boundary, the angle of the rearview mirror of the two parts is different. The inside is basically 1:1 like the general rearview mirror, while the outside is very different.

2. We can find that the viewing angle on the outside is larger, which can better cover the rear vision, because the dotted line part uses rearview lenses with higher curvature, and the combination of the two can better ensure the safety of our daily driving.

3. As we all know, when driving the rear is our blind spot, with such a rearview mirror can reduce the blind spot, whether it is daily driving or reversing to provide us with greater vision, so as to improve the safety of our driving.

It is called the parallel line of the mirror, through which you can judge whether the image is deformed, you can judge the sight distance of the car, you can reduce the blind spot, and then you can also put the scene in the rearview mirror into the hall to reduce the occurrence of accidents.

This dotted line is to observe the position of the side of the body, you can better observe the empty rearview mirror, to avoid the situation of blind spots, this dotted line is actually a reference point, which is round blind like when reversing the cavity is not easy to have an accident.

It is a double-curvature rearview mirror that reduces blind spots, consisting of two parts, one flat and one concave, with the dotted line being their cutout.

The scientific name of the rearview mirror with a black dotted line on the mirror surface is called "double curvature rearview ruined mirror", which is the dividing line to distinguish the mirror area with different curvature, on the side close to the body, the curvature of the rearview mirror is smaller, similar to the ordinary rearview mirror, mainly used to observe the road conditions close to the vehicle, and the curvature of the rearview mirror on the outside of the dashed line is larger, so that there is an effect similar to the convex mirror, looking at the past in the driver's seat, the area can be mapped out of the image reeds The range will be wider, In this way, the driver of the vehicle can better grasp the implementation of the vehicle from a distance, which is conducive to ensuring driving safety.

The dotted line on the rear mirror is the dividing line of the double-curvature rear with the large mirror, and the outside of the dotted line of the hyperboloid rearview mirror is the large curvature. The inside of the dotted line is a small curvature, which reduces the driver's misjudgment of the distance behind the vehicle.

This is done to better determine the distance, help people to make better judgments, and can also be well observed through the rearview mirror in some special weather.

The radius of curvature of the inner area of the dashed line is large, and the situation near the side of the car can be observed. More rear body can be seen outside the dotted line, and the combination of the two curvatures can effectively reduce the blind spot of the rearview mirror and reduce the danger.

Originally, this kind of rearview mirror with dotted lines was called "double curvature rearview mirror". The biggest feature of this kind of rearview mirror is that there is a dotted line in the third part outside, and the outside of the dotted line is the outside of the rearview mirror. Due to the small radius of curvature, the driver can see the rear panorama, which is mainly used to observe the situation on the far side of the body, eliminate blind spots when cornering, and expand the field of view by two times.

For example, when changing lanes, you can better see the cars coming from behind. On the one hand, it makes up for the problem of small rear view range of the plane mirror, and on the other hand, it also basically solves the distortion problem caused by the large radius of curvature of the convex part.

The working principle and advantages, the principle of double curvature mirror technology is as follows:

According to the model, the position of the driver's eyepoint, the relative position of the rearview mirror and the visual requirements, the optical principle and data method are used to select different curvature radii for different visual angles of the vehicle, and the transition is smooth. In this way, the field of view can be further expanded and the blind spot can be narrowed without distortion. Its advantage is that it not only meets the national mandatory standards, but also solves the problem of blind spots.

In addition, the influence of the rearview mirror on the drag coefficient can be achieved, and this coefficient has a great impact on the wind resistance. The double curvature rearview mirror can reduce the volume of the rearview mirror, which will naturally reduce the drag coefficient of the vehicle, so as to achieve the effect of reducing fuel consumption by collapse. In addition to this, the rearview mirror is also a noise maker when driving at high speeds.

Therefore, reducing the volume of the rearview mirror can also effectively reduce the noise of the rough vehicle in the group shed. Kill two birds with one stone.

Double-curvature mirror technology was previously only used in high-end cars. However, with the gradual decline in cost, more and more models have begun to popularize double-curvature rearview mirrors, which is undoubtedly a great boon for car owners.
