The invention discloses an expansion sealing rubber block structure for a vehicle cavity water sealing seam, which comprises a framework mounted on the inner side of a vehicle body metal plate, polystyrene foam grooves are symmetrically formed in one side, close to the vehicle body metal plate, of the framework up and down, high-density polystyrene foam blocks are filled in the polystyrene foam grooves, and a sol placing groove is formed in the framework on the rear side of the polystyrene foam grooves. A thermal fluidity melt glue block is arranged in the sol placing groove, a filling groove is formed between the polystyrene foam grooves in the side, close to the automobile body metal plate, of the framework, and a communicating groove opening is formed between the filling groove and the sol placing groove; according to the invention, the upper and lower groups of high-density foamed rubber blocks are matched with the thermal flowability melt rubber blocks to carry out foaming filling on gaps among metal plates of a vehicle body, so that 100% sealing filling is realized, the sealing property of a cavity of the vehicle body is greatly improved, the watertight performance of the vehicle body is improved, and meanwhile, the specially-made high-density foamed rubber blocks and the thermal flowability melt rubber blocks effectively enhance the strength and flame retardant property of the sealant.

    本发明公开一种用于车辆空腔水密封缝的膨胀密封胶块结构,包括所述骨架安装在车身钣金内侧,所述骨架靠近车身钣金一侧上下对称设有发泡胶槽,所述发泡胶槽中填充有高致密发泡胶块,所述发泡胶槽后侧的骨架设有溶胶放置槽,所述溶胶放置槽中设有热流动性熔胶块,所述骨架靠近车身钣金一侧的发泡胶槽之间设有填充槽,所述填充槽与溶胶放置槽之间设有连通槽口;本发明由上下两组高致密发泡胶块配合热流动性熔胶块对车身钣金间隙发泡填充,实现100%密封填充,使车身空腔的密封性大幅提升,提升车身水密性能,同时特制的高致密发泡胶块和热流动性熔胶块有效增强密封胶的强度和阻燃性能。
