Description

A device for fully automatic follow-up rearview mirror

technical field

The utility model relates to an electronically controlled rearview mirror device, in particular to a fully automatic follow-up rearview mirror device.

Background technique

The car rearview mirror is one of the main driving safety devices. It is like two eyes of a person, always watching various situations on the road behind the car on both sides. Its function is to provide the driver with a rear view. The field of view and blind area of the rearview mirror are shown in Figure 1. The design principle is that in addition to meeting the requirements of relevant regulations and standards, the radius of curvature, mirror size, installation position and number should be correctly selected. Due to the blind area of vision when changing lanes, turning, and reversing, it will cause collisions, collisions, etc. At present, the external rearview mirrors of automobiles at home and abroad all have problems of insufficient vision and blind spots (commonly known as dead spots) to varying degrees. Overcoming the blind spots of the external rearview mirrors of automobiles has long been the goal of many domestic and foreign experts to study and tackle difficulties, but it has not been ideally solved for a long time.

When a car driver performs operations such as reversing into a garage or pulling over to park, the side of the right side of the car tire is often scratched by the roadside platform because the angle of the rearview mirror is not adjusted properly, which is difficult to avoid even for skilled drivers . Generally, mid-to-high-end cars are equipped with electrically adjustable rearview mirrors. The driver can adjust the position of the rearview mirror through the electric control system to obtain the best view of the rearview mirror. However, general family cars cannot follow up, that is, the angle is automatically adjusted to solve the problem of blind spots. Moreover, it is inconvenient for the driver to see the road conditions on the right rear road when reversing, which requires that the rearview mirror can be adjusted vertically. These have all brought great inconvenience for the driver's operation. Therefore, it is not possible to meet the requirements only by using electric-controlled rearview mirrors. It is also necessary to realize follow-up control on the basis of electric power to eliminate blind spots and improve the rapidity of adjustment.

The utility model can effectively adjust the position of the rearview mirror, timely and effectively eliminate blind spots, and enhance driving safety and intelligence. This device completely eliminates the spatial blind spots, jet lag blind spots, visual persistent blind spots and visual errors that exist in the traditional rearview system, so that the driver does not need to "look left and right" or "look forward and backward", and can accurately judge whether to turn or not by looking straight ahead. Whether it is safe to change lanes, accurately see the road conditions and vehicle conditions behind and drive safely, so as to realize no blind spots and no dead angles in the rearview mirror. The rearview mirror can correctly guide the driver's operation and eliminate car accidents caused by blind spots and parallax.
