The invention provides a method for preventing rainwater of a streaming media rearview mirror, which is characterized in that a hydrophobic coating material is arranged on the surface of a shell at the end, close to a camera, of the streaming media rearview mirror, the area of a hydrophobic coating area accounts for 20-50% of the surface of the shell, and a water drop contact angle formed on the surface of the hydrophobic coating material is greater than 90 degrees. The method for obtaining the hydrophobic coating comprises the steps of spraying hydrophobic paint or pasting a film, the hydrophobic paint contains micron or nano-scale particles, and the pasting film is a macromolecule pasting film with a micron structure or a nano structure. Based on the technical scheme of the invention, the retention time of raindrops on the surface of the streaming media rearview mirror shell is greatly shortened, the raindrops quickly slide down, and the raindrops are effectively prevented from sliding along the camera shell and covering the surface of the camera. By means of the design expectation, the performance of the streaming media rearview mirror under the severe weather condition can be remarkably improved, the camera is kept clean and dry, and therefore the driving safety is improved.

    本发明提供了一种用于流媒体后视镜防雨水的方法,在流媒体后视镜近摄像头端外壳表面设置具有疏水性能的涂层材料,疏水涂层区域面积占外壳表面的20%‑50%,在疏水涂层材料表面上形成的水滴接触角大于90°,获得疏水涂层的方法为喷涂疏水涂料或贴膜,疏水涂料包含微米或纳米级颗粒,贴膜是带微米结构或纳米结构的高分子贴膜。基于本发明的技术方案,雨滴在流媒体后视镜外壳表面上的停留时间将大大减少,快速滑落,有效防止雨滴沿摄像头外壳滑动并覆盖摄像头表面。这种设计预期将显著提高流媒体后视镜在恶劣天气条件下的性能,保持摄像头的清洁和干燥,从而提高行车安全性。
