The invention relates to the technical field of automobile exhaust, and discloses an automobile exhaust device which comprises an exhaust protection structure, a lower flow guide mechanism is arranged at one end of the exhaust protection structure, a pump flow anti-immersion mechanism is installed in the exhaust protection structure, and an upper edge constant pressure mechanism is installed on the surface of the exhaust protection structure. A heat dissipation supporting mechanism is arranged at the top of the exhaust protection structure, and a flow guide soft connection mechanism is arranged at one end of the heat dissipation supporting mechanism. According to the automobile exhaust device, through the arrangement of the exhaust protection structure, the lower flow guide mechanism, the pump flow anti-immersion mechanism, the upper edge constant pressure mechanism, the heat dissipation supporting mechanism and the flow guide soft connection mechanism, automobile exhaust can be accelerated and pressurized through the pump flow anti-immersion mechanism when an automobile wades into water, and the exhaust emission capacity is improved; and meanwhile, the rotating flow pushing spiral fan continuously pushes outwards to actively drain water, so that water flow is prevented from entering the silencer.

    本发明涉及汽车排气技术领域,且公开了一种汽车排气装置,包括:排气防护结构,所述排气防护结构的一端设置有下导流机构,所述排气防护结构的内部安装有泵流防浸机构,所述排气防护结构的表面安装有上沿恒压机构,所述排气防护结构的顶部设置有散热支撑机构,所述散热支撑机构的一端设置有导流软接机构。该汽车排气装置,通过设置的排气防护结构、下导流机构、泵流防浸机构、上沿恒压机构、散热支撑机构和导流软接机构,能够在汽车涉水时通过泵流防浸机构对汽车尾气加速增压,提高尾气排放能力,并同时通过旋转的推流螺旋扇不断向外推送主动排水,避免水流进入消音器内部。
