Technical Field

The invention relates to the field of automobile accessories, in particular to a folder for a rearview mirror of a truck.

Background

The vehicle-mounted rearview mirror is an important part on an automobile, and a driver can observe the rear and the vision of two sides only through the rearview mirror in the driving process, so that the safety of lane changing and turning around of the automobile can be guaranteed. The original vehicle-mounted rearview mirrors are only simply installed on two sides of an automobile, and can only be broken by hands when needing to be adjusted, so that a driver cannot adjust the rearview mirrors in the driving process and can only park to the roadside for adjustment, and the situation that the rearview mirrors cannot be timely adjusted and scratched can be caused when the driver passes through narrow areas or meets the automobile. Therefore, to solve these problems, electrically controlled automobile rearview mirrors have been developed. However, these conventional electric automobile rearview mirrors are only applied to cars, and there is no corresponding electric rearview mirror for trucks and other medium-large automobiles, and after all, the vehicle rearview mirrors used for medium-large automobiles are different from those used for small cars, and the vehicle heights and body lengths of the two are greatly different, which results in that the vehicle rearview mirrors used for small cars are almost completely not suitable for the medium-large automobiles such as trucks.

Disclosure of Invention

The present invention is directed to solving at least one of the problems of the prior art. Therefore, the invention provides a convenient-to-use rearview mirror folder for a truck.
