Outside rear-view mirror and method for adjusting outside rear-view mirror when used for vehicle

Abstract

The invention belongs to the technical field of vehicle accessories, and particularly relates to an outside rear-view mirror and a method for adjusting the outside rear-view mirror when used for a vehicle. The outside rear-view mirror comprises a reflective mirror set and a shell. The reflective mirror set is composed of a first reflective mirror and a second reflective mirror. The first reflective mirror and the second reflective mirror are vertically arranged in the shell in the vertical direction. A drive mechanism is located in a cavity formed between the reflective mirror set and the shell and connected with the first reflective mirror and the second reflective mirror to drive the first reflective mirror and the second reflective mirror to rotate in the shell. Both the first reflective mirror and the second reflective mirror are convex lenses. The curvature radius of the first reflective mirror is the same as that of the second reflective mirror. By the adoption of the outside rear-view mirror, the dead zone phenomenon of a conversional outside rear-view mirror can be greatly and effectively avoided, vision disparity is reduced, and erroneous judgment is reduced; and the method for adjusting the outside rear-view mirror is reliable, practical and suitable for being widely applied and popularized as a vehicle accessory.

Description

technical field [0001] The invention belongs to the technical field of vehicle accessories, in particular to an exterior rearview mirror and an adjustment method for a vehicle using the exterior rearview mirror. Background technique [0002] The conventional exterior rearview mirror has a blind spot in a certain area behind the side, which is called the blind spot of the conventional exterior rearview mirror in this paper. [0003] There are data to show that many traffic accidents, especially the traffic accidents when the car changes lanes, are all caused by the blind spot of the conventional exterior rearview mirror, and the driver cannot observe the coming car from the side. Therefore, how to effectively eliminate the blind spots of conventional exterior rearview mirrors has become the focus of automobile rearview mirror design. [0004] It can be seen from the optical principle that when the size of the rearview mirror is constant, the main method to expand the field o...

Problems solved by technology

[0005] In order to comply with the regulations and reduce the blind area, there are generally two current methods. One method is to use a hyperboloid or variable-curved large-field rearview mirror. This method mainly considers the difference in imaging so that it cannot be used with a smaller curvature. , so the viewing area can be increased limitedly, and the blind area cannot be completely eliminated, and the processing of this kind of hyperboloid or variable-curved lens is relatively difficult.

[0006] Another method is: use two mirror combinations, one is a large-curvature rear-view primary mirror that meets the standards, and the other is a small-curvature rear-view auxiliary mirror; the disadvantage of this method is (1) The curvature of the rear-view auxiliary mirror is small , the imaging difference between the main mirror and the imaging is large, which is easy to cause misjudgment; (2) Due to the design defect of the auxiliary mirror, the blind area cannot be completely observed by the auxiliary mirror; (3) The overlapping of the viewing area of ​​the auxiliary mirror and the viewing area of ​​the main mirror is too large (4) Due to the problem of the setting position and adjustment angle of the auxiliary mirror, it will still cause a blind spot with a large angle
