The invention relates to a door opening sealing strip assembly. The sealing strip assembly is installed between a vehicle door and a side wall and comprises a compression part and an installation part, the installation part comprises a framework and rubber wrapping the framework, the framework is of a U-shaped structure, and sealing teeth formed by rubber are arranged between the framework and a side wall metal plate from top to bottom, and are sequentially a first sealing tooth, a second sealing tooth, a third sealing tooth and a fourth sealing tooth. The first sealing tooth and the second sealing tooth are made of a foamed rubber material, and the second sealing tooth and the third sealing tooth are made of dense rubber, so that the assembly convenience and the strength after assembly are ensured, and meanwhile, the sealing strip assembly can adapt to metal plate thicknesses of different vehicle types; the installation part framework adopts a steel belt, so that the installation strength is ensured; and the compression part is mainly made of expanded polystyrene (EPDM), exhaust holes are formed in two compression bubbles respectively, and the proper compression load in the compression process is guaranteed. The sealing strip assembly is good in universality, the vehicle door is free of water leakage, air leakage and other problems after loading, and the door closing force andthe door closing sound quality both meet the requirements.

    本发明涉及一种门洞密封条总成,该密封条总成,安装在车门与侧围之间,包括压缩部和安装部,安装部包括骨架和包覆在骨架外的橡胶,所述骨架呈U型结构,骨架与侧围钣金之间至上而下设有由橡胶形成的密封齿,依次为第一密封齿、第二密封齿、第三密封齿和第四密封齿。第一密封齿和第二密封齿采用发泡橡胶材料,第二密封齿和第三密封齿采用密实橡胶,保证装配便利性和装配后的强度,同时能适应不同车型的钣金厚度;安装部骨架采用钢带,保证安装强度;压缩部以发泡橡胶(EPDM)为主要材料,在两个压缩泡处分别设置排气孔,保证压缩过程中合适的压缩负荷。本发明通用性好,装车后车门无漏水、漏气等问题,关门力及关门声品质均满足要求。
