The invention provides an outside rear-view mirror for a vehicle and a system for reducing wind noise of the outside rear-view mirror. The outside rear-view mirror comprises a rear-view mirror shell and a rear-view mirror base used for connecting the rear-view mirror shell to the body of the vehicle, wherein the outer surface of the rear-view mirror base is coated with a multi-layer film structurewith a changeable shape; and the multi-layer film structure is constructed to be tightly attached to the outer surface of the rear-view mirror base when a vehicle speed is lower than a preset speed,and when the vehicle speed is higher than or equal to the preset speed, the shape of the multi-layer film structure is adjusted according to the conditions of the vehicle speed and noise in the vehicle, so airflow flowing through the outer rear-view mirror is guided to flow to a position below a vehicle window of the vehicle. According to the scheme in the invention, the demands for attractivenessand wind noise reduction can be met at the same time, the requirements for no influence on the attractiveness of the rear-view mirror at a low speed and reduction in the wind noise at a high speed are met, and the requirement for wind noise optimization at different vehicle speeds is met.
本发明提供了用于车辆的外后视镜及降低外后视镜风噪的系统。该外后视镜包括后视镜壳体以及用于将所述后视镜壳体连接在车辆的车身上的后视镜底座,所述后视镜底座的外表面包覆有可改变造型的多层膜结构;所述多层膜结构构造成在车速低于一预设速度时紧贴所述后视镜底座的外表面,并在所述车速高于或等于所述预设速度时根据车速、车内噪声的情况调整造型,从而引导流过所述外后视镜的气流向所述车辆的车窗下方流动。本发明方案可以兼顾美观与降低风噪的需求,实现在低速时不影响后视镜美观,高速时降低风噪的需求,并且满足在不同车速下进行风噪优化的需求。
