The invention belongs to the technical field of automobile sealing strips and discloses an automobile front and rear door sealing strip. The strip comprises a sealing strip body; the sealing strip body comprises a sound insulation layer, a sound insulation pad, an elastic layer, a flame retardant layer, shock absorption pieces, elastic damping clamping pieces and shock absorption keels. The soundinsulation layer and the sound insulation pad enhance a sound insulation effect, a certain sound insulation effect is enhanced by utilizing the elastic layer and the flame retardant layer, and therefore, comprehensive performance can be greatly improved; the damping keels, the elasticdamping clamping pieces and the damping pieces are matched with one another so as to realize shock absorption, andtherefore, vibration during sound propagation is reduced, a sound insulation effect is achieved, vibration during the closing of a vehicle door can be reduced, and a better sound insulation effect isrealized; a fixing plate and a supporting block are additionally arranged on the front face of the vehicle door, so that part of a sealing strip body is clamped by the fixing plate and the supportingblock; screws penetrate through the sealing strip body to be in threaded connection with threaded holes, so that the sealing strip body is more stable, loosening is avoided, and a mounting structure is more stable.
本发明涉及汽车密封条技术领域,且公开了一种汽车前后门密封条,包括密封条本体,所述密封条本体包括隔音层、隔音垫、弹性层、阻燃层、减震件、弹性阻尼卡件和减震龙骨。利用隔音层和隔音垫增强隔音效果,并利用弹性层和阻燃层加强一定的隔音效果,大幅提升综合表现,利用减震龙骨、弹性阻尼卡件和减震件相配合,进行减震,减少音量传播时的振动,达到隔音的效果,且可减少车门关闭时的振动,实现了隔音效果更好的目的,通过在车门的正面加装固定板和托块,使得密封条本体的局部被固定板和托块卡住,并利用螺钉贯穿密封条本体与螺纹孔螺纹连接,使得密封条本体更加稳定,避免松动,实现了安装结构更加稳定的目的。
