Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to an automobile auxiliary device technical field, concretely relates to automatic device that turns over down of control outside rear-view mirror lens when car is backed.
[ background of the invention ]
When a driver backs, the driver must rely on the rearview mirrors on the left side and the right side of the vehicle body to observe the obstacle situation behind the vehicle so as to ensure safety. In order to make the driver see the view as large as possible from the rearview mirror, the rearview mirror adopts a convex mirror (also called a wide-angle mirror).
Theoretically, the larger the curvature of the curved mirror, the wider the field of view observed. However, the mirror surface with a larger curvature also has a larger distortion and distortion of the image. When an automobile manufacturer selects the backing lens, a balance point must be taken on two aspects of the size of a visual field and the distortion degree of an image, so that the curvature of the backing lens is not particularly large.
In the actual use process, the following problems exist:
one is that the driver observes the rear condition of the vehicle from the rearview mirror, and a large blind area exists.
Secondly, as shown in fig. 1, when the automobile runs forwards, the angle of the rearview mirror can be adjusted to the horizontal direction of the sight line of the driver at the rear, so that the driver can conveniently observe the coming automobile at the rear, and reference is provided for overtaking and merging. When backing up, as shown in fig. 2, the rearview mirror needs to be turned down to be adjusted to be able to observe the road surface behind (to see the rear wheel as best) so as to observe the road condition and obstacles on the road surface behind.
In view of the above two problems, when a driver drives a car, in order to better observe the rear situation, the driver needs to adjust the rearview mirror of the original car to be higher to the horizontal direction of the rear sight line observed by the driver when the driver moves forward. When backing, the mirror needs to be adjusted down (turned down) to be able to see the rear tire through the rearview mirror adjusting switch of the original vehicle. This switching process is cumbersome and the left and right rear mirrors need to be adjusted separately, which makes the driver feel very inconvenient.
