The invention discloses a rearview mirror sealing structure which is arranged at the joint of a rearview mirror body and an automobile body outer plate and comprises a metal base, a base decorative cover, a sealing rubber mat, via hole foam and an automobile door outer plate. A base gap is reserved between the metal base located on the inner side of the base decorative cover and the base decorative cover, and the sealing rubber mat is installed in the base gap, so that the metal base and the base decorative cover are in sealing fit; the lower end of the sealing rubber pad is in interference sealing fit with the automobile door outer plate; the via hole foam is filled in wire harness via hole gaps at the upper end and the lower end of the metal base to realize sealing fit; and a closed cavity is formed between the rearview mirror body and the automobile body outer plate under the sealing fit of the sealing rubber pad and the via hole foam. According to the sealing structure, air flow can be prevented from circulating between the rearview mirror and the adjacent automobile door outer plate, the NVH performance of an automobile is effectively improved, noise propagation is weakened, and the noise reduction effect is achieved.

    本发明公开了一种后视镜的密封结构,设置在后视镜本体与车身外板连接处,所述密封结构包括:金属底座、底座装饰罩、密封胶垫、过孔泡棉以及车门外板;位于底座装饰罩内侧的金属底座与底座装饰罩之间留有底座间隙,所述密封胶垫安装在所述底座间隙内,使金属底座与底座装饰罩之间密封配合;所述密封胶垫下端与车门外板过盈密封配合;所述过孔泡棉填充在金属底座上下两端的线束过孔间隙内,实现密封配合;在所述密封胶垫和过孔泡棉的密封配合下,后视镜本体与车身外板之间形成密闭空腔。本发明所述密封结构能够阻断空气流在后视镜与相邻的车门外板之间流通,有效车辆NVH性能,减弱噪声传播,起到降噪的作用。
