Mounting buckle structure with shared hole and clamped connection of cavity sound insulation rubber blocks

Abstract

The invention provides a mounting buckle structure with cavity sound insulation rubber blocks sharing holes and clamped with each other, and relates to the field of automobile parts. The structure comprises a first sound insulation rubber block, a second sound insulation rubber block connected with the first sound insulation rubber block through an elastic bracket, and a mounting buckle structure, the first sound insulation rubber block and the second sound insulation rubber block are both provided with matched clamping plates in the Z direction, and the installation buckle structure comprises a first buckle and a second buckle, wherein the first buckle is formed by two fishhook-shaped buckle units through a connecting rod, and the second buckle is formed by combining the two buckle units. In order to solve the problem of poor sealing caused by the fact that a large cavity of an outer cavity on an A column needs to avoid metal plate mechanical motion interference, through the buckle structure design which can be interlocked and share one mounting opening, both product performance and cost are well considered, the effect of improving NVH can be achieved, and the effects of low cost and simple process can be achieved.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an installation buckle structure in which cavity sound-insulating rubber blocks share holes and are locked together. Background technique [0002] Nowadays, the requirements for the five-star collision of automobiles and the collision of China Insurance Research Institute are getting higher and higher. It is required to open as few holes as possible on the sheet metal parts such as the A-pillar and B-pillar of the automobile to ensure the safety of the collision. For the cavity sound insulation adhesive For a block product, two parts are required to seal the inner cavity and the outer cavity, and at least two installation holes are required. Now the sheet metal parts can only provide one installation hole, which requires us to design a hole that can install two parts, and to be able to Guarantee the manufacturability of installation manufacturability and parts.
