Background technique

With the continuous development of science and technology, people have put forward higher and higher requirements for the comprehensive performance of products. Specifically, many countries impose strict regulations on the noise standards of products. Studies have shown that for many products, the better the sealing performance of the product, the less noise the product produces. The following is an example of the noise problem of a car. There are many sources of car noise. The noise generated by the engine is an important source of car noise. Due to the high noise generated by the automobile engine, the soundproofing pad is usually installed on the front wall of the car for sound insulation. The soundproofing pad installed on the front wall is an important soundproofing component of the car, which can greatly reduce the noise generated by the engine. Especially effective for reducing high frequency noise generated by the engine. However, since some electronic components are required to be mounted on the front wall of the automobile, a large number of bolts for fixing the electronic components are provided, and a sound insulating mat mounted on the front wall of the automobile also requires a large number of bolt holes. Considering the problem of assembly error, the size of the bolt holes machined on the soundproofing pad is generally much larger than the size of the bolt, which causes the direct exposure of the sheet metal in the front wall of the car, which seriously affects the sound insulation effect of the soundproof pad.

In recent years, in order to solve the sealing problem at the bolt holes on the front wall of the automobile, those skilled in the art have proposed a lot of sealing methods for the bolt holes on the front wall. Specifically, for the mounting of components such as a vehicle body controller, a gasket is usually installed under the mounting foot of the component so that the soundproofing pad can be pressed under the gasket to achieve a sealing and soundproofing effect. However, when the component needs to be mounted in a non-planar area of the front wall, since the distance between the gasket and the non-planar area is small, the gasket cannot be completely matched with the soundproof pad, thereby directly leading to the front wall sheet metal. Exposure has seriously affected the sound insulation of the soundproof mat.
