Background

The wind resistance of automobiles and ships is an important factor influencing the power consumption of the automobiles and the ships, particularly, the wind resistance is the maximum energy consumption in the driving process for high-speed vehicles with the driving speed of more than 90Km/h because the air resistance is in direct proportion to the square of the speed. Therefore, people want to try to design and manufacture the wind resistance of the high-speed moving object to be the lowest. Taking a car as an example, the wind resistance of the whole car is 0.28-0.35 at present, and the super sports car is lower. The influence value of the rearview mirror of the car on the wind resistance coefficient accounts for 0.01-0.03. For example, for a car with a general wind resistance of 0.3, the wind resistance of the outer rearview mirror accounts for about 7% of the total wind resistance of the whole car, so that when the car runs at a high speed, about 7% of energy consumption is spent on overcoming the wind resistance of the outer rearview mirror, and for these reasons, in the design of the car, various technical measures are taken for reducing the wind resistance of the outer rearview mirror, and the design of a smooth streamline is also made on the appearance of the car. In addition, the outer rearview mirror generates wind resistance, and is positioned close to a window, so that air disturbance is rubbed with a vehicle body and the outer rearview mirror during high-speed running, great aerodynamic noise is generated, and the wind noise of the outer rearview mirror is one of the most prominent noise sources.

If the external wind resistance of the external rearview mirror can be reduced by 50%, the wind noise can be obviously improved. How to reduce the wind resistance of the exterior rearview mirror is an urgent problem to be solved.

Among the prior art, the rear view mirror includes: the shell, support column and lens, the lens is located vertical direction, shell one side is the windward side, the sunken mounting groove that forms of shell opposite side, the lens is installed in the mounting groove, the shell passes through the support column and installs on the automobile body, the shell is seen from the direction parallel with the support column, the shell is the quarter ellipse, shell one side non-circular arc face is used for seting up the mounting groove, shell opposite side non-circular arc face is used for the erection bracing post, because the shell depressed face is non-circular arc face, because the influence of wind current, lead to the windage increase, current rear-view mirror windage coefficient is 0.4 ~ 0.6 usually, consequently, the windage of this rear-view mirror is very big, lead to the vehicle to produce extra resistance at.
