What kind of mirror is that rearview mirror of the car, wow?

Car mirrors are convex mirrors, except for the interior mirrors. The exterior mirrors on both sides of the car are usually convex mirrors, the mirror surface is spherical, with different sizes of curvature radius, its image is smaller than the eye, but the field of view is large, like the role of the camera's "wide-angle lens", so some people call it a wide-angle lens.

The rearview mirror is divided by the installation position, and is divided into the outer rearview mirror, the lower rearview mirror and the inner rearview mirror. In terms of use, the exterior mirrors reflect the rear side of the car, the lower mirrors reflect the front and bottom of the car, and the interior mirrors reflect the rear and interior of the car. Depending on the use, the mirror structure will be different.

There are two main types of mirrors in general, one is a plane mirror, as the name suggests, the mirror is flat, and the term is "the radius of surface curvature r is infinite", which is the same as the general family mirror, and the image can be obtained with the same size as the eye, and this plane mirror is often used as an inner rearview mirror. The other is a convex mirror, the mirror is spherical, with a radius of curvature of different sizes, its image is smaller than that of the eye, but the field of view is large, like the role of the camera's "wide-angle lens", this convex mirror is often used as an exterior mirror and a lower rearview mirror. Cars and other light passenger cars are generally equipped with exterior and interior mirrors, and large commercial vehicles (buses and trucks) are generally equipped with exterior mirrors, lower mirrors and interior mirrors.

The driver's side is a flat mirror (a true reflection of the distance between the vehicles, according to traffic regulations, because overtaking is from this side), while the passenger side is a convex mirror (expanding the rearview range).

The rearview mirror inside the car is called **rearview mirror.

**Rearview mirror is to reflect the rear of the car and the situation in the car,**The most basic function of the rearview mirror is to observe the condition of the rear passengers, especially if there are children in the back row, the driver in the front row will have to observe the children in the back row from time to time, because driving will have certain safety hazards.

**The role of the rearview mirror:

1. Observe the road conditions behind you.

When driving in the country, you will often change lanes left and right depending on the road conditions. When you are ready to change lanes, turn on your turn signal in advance, and then look at the vehicle behind you through the rearview mirror to confirm that it is safe to change lanes. But at this time, many people will ignore the situation of the rear car, at this time, the ** rearview mirror can see whether the rear vehicle has turned signals or has the intention of changing lanes.

2. Look at the rearview mirror when braking suddenly.

When there is an emergency situation in front of you that requires sudden braking, you can observe the ** rearview mirror to know whether there is a car behind you that is trailing very tightly, so that you can relax the brakes appropriately according to the distance from the front to avoid rear-end collisions.

3. Judge the distance from the rear car.

When the driver is driving, he should mention the spirit of twelve, always pay attention to the situation around the car, especially the rearview mirror, through the rearview mirror can judge the distance between the rear car, in the rearview mirror just to see the front wheels of the rear car, the distance between the front and rear cars is about 13 meters, when you see the grid, about 6 meters, just when you can't see the grid, about 4 meters before and after.

There are two main types of car mirrors . One is a flat mirror, which is flat as the name suggests. This kind of mirror can get an image of the same visual size as a normal household mirror.

This type of flat mirror is often used as a rearview mirror in a car. The other is a convex mirror, which is spherical and has a different radius of curvature. Its image is smaller than visual, but the field of view is wide, which seems to be the role of the camera's "wide-angle lens".

This convex mirror is often used as an exterior and lower mirror.

Rearview mirrors are divided into exterior mirrors, lower mirrors, and interior mirrors according to the installation location. According to usage, the exterior mirrors reflect the rear side of the car, the lower mirrors reflect the front lower part of the car, and the interior mirrors reflect the rear and interior of the car. The mirror structure will be different for different purposes.

There are two kinds of mirrors in general, one is a plane mirror, as the name suggests, the mirror is flat, and it is represented by "infinite curved surface curvature radius r", which is the same as ordinary household mirrors, you can get the same visual size of the image, this plane mirror is often used as an inner rearview mirror. The other is a convex mirror, which is spherical and has a different radius of curvature. Its image is smaller than the vision, but the field of view is large, similar to the "wide-angle lens" of a camera.

This convex mirror is often used as an exterior and lower mirror. Light passenger cars such as sedans are generally equipped with exterior and interior mirrors, and large commercial vehicles (buses, trucks) are generally equipped with exterior mirrors, lower mirrors and interior mirrors.

The rear mirror of a car is called a rearview mirror.

The rearview mirror is a tool for the driver to directly access external information such as the rear, side, and bottom of the car while sitting in the cab seat. In order to facilitate the driver's operation, prevent the occurrence of driving safety accidents, and ensure personal safety, all countries have stipulated that rearview mirrors must be installed on the car, and all rearview mirrors must be able to adjust the direction.

According to the adjustment method of the rearview mirror, it can be divided into two types: exterior adjustment and interior adjustment.

1.This mode of car outside adjustment type is in the parking state, by directly adjusting the position of the mirror frame or mirror surface by hand to complete the adjustment of the angle of view, this mode is time-consuming and laborious, it is difficult to complete conveniently at one time, the driver needs to stretch out the window with his hand on the seat to adjust, and it is very inconvenient to adjust in the case of driving, rainy days, etc. Generally, large cars, trucks and low-end buses all adopt the external adjustment method to reduce costs.

2.This method of in-vehicle adjustment can provide more convenient conditions for the driver to adjust the rearview mirror and observe the rear vision during driving. Most of the mid-to-high-end cars use the in-car adjustment method.

This method is divided into two types: manual adjustment (wire cable transmission adjustment or handle adjustment) and electric adjustment type.

Reversing mirrors. 1. For the rearview mirror in the car, adjust the left and right positions to the left edge of the mirror and cut to the right ear of your image in the mirror. This means that in normal driving situations, you can't see yourself from the rearview mirror in the car, and the upper and lower positions are to put the distant horizon in the mirror**.

2. For the left rearview mirror, the upper and lower positions are to put the distant horizon in the **, and the left and right positions are adjusted to the body occupying the mirror range of 1 4.

3, for the right side of the rear-view mirror, because the driver's seat is located on the left side, so the driver's grasp of the right side of the body is not so easy, coupled with the need to sometimes stop on the side of the road, for the right side of the rear-view mirror in the adjustment of the upper and lower position of the ground area to be larger, accounting for about 2 3 of the mirror. The left and right positions are also adjusted to the body occupies 1 4 area.
