Bypass sealing supporting rubber block

Abstract

The invention provides a bypass sealing supporting rubber block, and relates to the field of automobile NVH, the bypass sealing supporting rubber block comprises a rubber block structure, a positioning column and a fixing buckle, the rubber block structure comprises a fixing framework and an expansion rubber block, a connecting part is arranged in the middle of the whole fixing framework, the positioning column and the fixing framework are integrally formed, and the positioning column is located on the edge of the fixing framework; a fixing hole is formed in the surface of the connecting part, and the fixing buckle is matched with the fixing hole. By using the positioning columns, on one hand, it is guaranteed that parts are accurately positioned during plate closing, the problems of displacement, mistaken assembly and the like are avoided, the spatial positions of the parts are accurate, and the sealing function of the cavity of the vehicle body metal plate is achieved; on the other hand, a certain degree of protection can be achieved when the rubber block and the metal plate are spliced, product shaking can be reduced in the preparation process of the spliced metal plate, and the sealing range of the size of the sealing cavity can be wider in the foaming process. The parts can be effectively assembled through positioning, and the problems of displacement and wrong assembly of the parts are reduced.

Description

technical field [0001] The invention relates to the field of automobile NVH, in particular to a bypass sealing support rubber block. Background technique [0002] Foam material rubber blocks are widely used in automobile sheet metal parts, mainly to reduce vibration and noise. The resin foam material products used in the existing rubber expansion blocks are relatively soft and easy to deform. Although the deformation is small after baking, there is a risk of insufficient sealing, but the cost is high. Therefore, a bypass sealing support is designed Glue blocks have become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a bypass sealing support rubber block. [0004] The present invention is achieved through the following technical solutions: a bypass seal supporting rubber block, which is charac...
