Do you know the Type of Rear View Mirror?

Mar. 24, 2020

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

1. Inner rearview mirror: Inner rearview mirror is a mirror for confirming the rear scene without changing the forward line of sight during driving.

2. Greatwall Rear View Mirror: Passenger cars generally install exterior rear view mirrors on the doors. Domestic cars are also installed on the fenders.

3. Down-view mirror: The down-view mirror allows the driver to see the outside of the front and rear wheels under the car body in the mirror directly in front of the driver's seat. If there are people or obstacles nearby, so as not to hurt people, objects and damage the vehicle, give the driver convenience and safety.

Classification by mirror shape of rearview mirror

It can be divided into three series: flat mirror, spherical mirror and double curvature mirror. In addition, there is another kind of prism mirror. The prism mirror has a flat mirror surface, but its cross section is prismatic. It is usually used as an anti-glare inner rearview mirror.

Classified by the material of the reflective film used for making mirrors

It can be divided into 4 types: aluminum mirror, chrome mirror, silver mirror, blue mirror (coating).

Classification by adjustment method of rearview mirror

It can be divided into two types: outside adjustment and inside adjustment.

1. Outside car adjustment This method is to adjust the angle of view by directly adjusting the position of the frame or the mirror in the parking state. This method is time-consuming and labor-intensive, and it is difficult to complete it at one time. The seat is extended out of the window for adjustment by hand, which is very inconvenient to adjust under driving and rainy conditions. Generally, large cars, trucks and low-grade passenger cars use outside adjustment to reduce costs.

2. In-car adjustment This method can provide a more convenient condition for the driver to adjust the rear-view mirror and observe the rear vision during driving. Most of the mid-range and high-end cars adopt in-car adjustment. This method is divided into two types: manual adjustment (wire rope drive adjustment or handle adjustment) and electric adjustment.

Because the position of the rearview mirror is directly related to whether the driver can observe the situation behind the car, it is more difficult for the driver to adjust its position, especially the rearview mirror on the side of the front passenger door. Therefore, the rearview mirrors of modern automobiles are basically electric and operated by electrical control systems.
