Problems solved by technology
However, in the actual use of the vehicle, often due to the poor sealing between the rearview mirror and the vehicle body, there is air flow between the rearview mirror and the outer door panel connected to it, resulting in noise.
[0004] In the prior art, an interference fit is used to seal the rearview mirror and the connected door outer panel, thereby restricting the external airflow from entering the interior of the rearview mirror, but this sealing form only blocks the external airflow from entering the rearview mirror. The interior of the mirror, but it cannot prevent the airflow inside the rearview mirror from entering the interior of the vehicle body, so that air enters between the rearview mirror and the adjacent door outer panel, resulting in vibration noise

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.
Description
technical field [0001] The invention belongs to the technical field of sealing of vehicle parts, and in particular relates to a sealing structure of a rearview mirror. Background technique [0002] With the development of the automobile industry, vehicles are equipped with more and more functions. In addition to paying attention to the original functions of automobiles, people gradually begin to pay attention to multiple attributes such as safety, comfort, convenience, and technology. Maintaining sound insulation in relatively private spaces is one way to improve comfort. [0003] Rearview mirror, as a part of China Unicom's internal and external environment, is particularly important to effectively reduce external noise. However, in the actual use of the vehicle, often due to poor sealing between the rearview mirror and the vehicle body, there is air flow between the rearview mirror and the outer door panel connected thereto, thereby generating noise. [0004] In the prio...
