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.

    本发明提供了一种旁路密封支撑胶块,涉及汽车NVH领域,包括胶块结构,定位柱以及固定卡扣,胶块结构包括固定骨架以及膨胀胶块,固定骨架整体的中部设有连接部,定位柱与固定骨架一体成型且位于固定骨架的边缘,连接部的表面设有固定孔,固定卡扣与固定孔相配合。本申请通过使用定位柱一方面保证零件在合钣时定位准确,避免出现移位、错装等问题发生,实现零件空间位置准确,满足车身钣金的空腔的密封功能;另一方面,能够对胶块与钣金合拼时进行一定程度的保护,在合拼钣金制备的过程中能够减小产品晃动,利于在发泡的过程中实现密封型腔尺寸的密封范围将更宽。能够有效地通过定位实现零件的装配,减少零件移位,错装的问题。
