Embodiment Construction

[0038] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0039] The sound-insulating rubber block in the automobile cavity provided by the present invention comprises a bracket body usually (nylon material) and a heat-expandable sealing material around the bracket body. The bracket body has two mounting buckles, which are fixed on the body panel gold on. In order to ensure the passability of the coating electrophoretic fluid, the distance between the foam layer and the sheet metal is 4-6mm, and the thermal expansion material is expanded through the coating electrophoretic oven to bond the carrier and the structural member wall, thereby sealing the entire cavity.

[0040] Two buckles are designed on the sound-proof rubber block, which can accurately fix the buckles on the sheet metal parts, prevent the rotation of the rubber block, and ensure t...

Abstract

The invention relates to a preformed sound-insulation rubber block and an installation method for the preformed sound-insulation rubber block, which are applied in a cavity of an automobile. The preformed sound-insulation rubber block comprises a support body, one or a plurality of installation buckles, and a cone-shaped through hole of a water manifold, wherein the support body is in a shape corresponding to the cross section of the cavity of the automobile; one or a plurality of installation buckles is / are arranged on the support body and is / are used for fixing the sound-insulation rubber block on a metal plate of the finished automobile; and the cone-shaped through hole of the water manifold is arranged in the middle of the support body and is used for penetrating through the water manifold.

Description

technical field [0001] The invention relates to the technical field of sound insulation for automobile cavities, in particular for automobile cavities where pipelines need to be arranged, and in particular to a preformed sound-insulating rubber block and an installation method thereof. Background technique [0002] With the continuous improvement of people's environmental awareness, the problem of vehicle noise has attracted great attention from the whole society. Among them, exterior noise control must be based on increasingly stringent environmental regulations and standards, while interior noise control is committed to meeting the increasingly stringent requirements of users for interior acoustic comfort. Therefore, improving the level of vehicle noise control has become a new focus of competition and technology development direction. In this context, the NVH (Noise / Vibration / Harshness) performance of the vehicle is gradually evolving into an important design indicator, ...
