Embodiment Construction

[0038] figure 1 A schematic perspective view of an exterior rearview mirror for a vehicle according to an embodiment of the present invention is shown. Such as figure 1 As shown, the exterior rearview mirror 10 includes a rearview mirror housing 1 and a rearview mirror base 2, and the rearview mirror base 2 is used to connect the rearview mirror housing 1 to the vehicle body. The outer surface of the rearview mirror base 2 is covered with a multi-layer film structure 21 whose shape can be changed. The multi-layer film structure 21 is configured to be close to the outer surface of the rearview mirror base 2 when the vehicle speed is lower than a preset speed, and to adjust the shape according to the vehicle speed and the noise inside the vehicle when the vehicle speed is higher than or equal to the preset speed. This directs the airflow past the exterior mirrors to flow under the windows of the vehicle.

[0039] According to the solution of the present invention, the outer s...

Abstract

The invention provides an exterior rearview mirror for a vehicle and a system for reducing wind noise of the exterior rearview mirror. The exterior rearview mirror includes a rearview mirror housing and a rearview mirror base for connecting the rearview mirror housing to the vehicle body, the outer surface of the rearview mirror base is covered with a shape changeable A multi-layer film structure; the multi-layer film structure is configured to be in close contact with the outer surface of the rearview mirror base when the vehicle speed is lower than a preset speed, and when the vehicle speed is higher than or equal to the preset speed, according to Vehicle speed, vehicle interior noise conditions adjust the styling so that the airflow flowing through the exterior mirrors is directed to flow under the windows of the vehicle. The solution of the present invention can take into account the requirements of aesthetics and wind noise reduction, realize the requirement of not affecting the appearance of the rearview mirror at low speeds, reduce the requirements of wind noise at high speeds, and meet the requirements of wind noise optimization at different vehicle speeds.

Description

technical field [0001] The invention relates to the technical field of reducing wind noise of vehicles, in particular to an exterior rearview mirror for a vehicle and a system for reducing wind noise of the exterior rearview mirror. Background technique [0002] With the development of automobile technology, ride comfort has been widely concerned, and wind noise complaints often rank among the top three among customer complaints. The wind tunnel test results show that when the vehicle speed exceeds 60km / h, the exterior rearview mirror is one of the main causes of wind noise. [0003] The rearview mirror base is a triangular or quadrilateral plate connecting the rearview mirror housing and the vehicle body. The shape of the existing rearview mirror base is mostly to meet the aesthetic requirements, and it is impossible to add structures to reduce wind noise on the base, such as vortex generators, partial streamlined shapes, etc., or it can only meet the wind noise optimizati...
