The invention discloses a sound insulation rear side enclosure face exhaust grille and a vehicle, and belongs to the technical field of automobile parts, the sound insulation rear side enclosure face exhaust grille comprises a grille plate arranged in a mounting hole of a rear side enclosure face, a pressure release valve side of the grille plate is provided with a sound absorption frame of a cavity structure in a buckled mode, and sound absorption cotton is laid on the outer side of the cavity structure of the sound absorption frame; the grating plate and the sound absorption frame are fixed to the periphery of the rear side enclosure face through plastic buckles arranged at the four corners respectively. According to the sound insulation rear side enclosure face exhaust grille and the vehicle, the grille plate is arranged in the mounting hole of the rear side enclosure face, the sound absorption frame of a cavity structure is arranged on the pressure release valve side of the grille plate in a buckled mode, and the sound absorption cotton is laid on the outer side of the cavity structure of the sound absorption frame; the grating plate and the sound absorption frame are fixed to the periphery of the rear side enclosure face through the plastic buckles arranged at the four corners respectively, so that noise which is directly transmitted to a passenger compartment from the outside of a vehicle through a pressure release valve due to the fact that the exhaust grating communicates with the vehicle body pressure release valve can be effectively restrained, and the NVH quality of the whole vehicle is improved.

    本发明公开了一种隔声后侧围护面排气格栅及车辆,属于汽车零部件技术领域,包括设置在后侧围护面的安装孔内的格栅板,所述格栅板的泄压阀侧扣设有空腔结构的吸音架,所述吸音架的空腔结构外侧敷设有吸音棉,所述格栅板和吸音架分别通过设置在四角的塑料卡扣固定在后侧围护面的四周。本发明提供了一种隔声后侧围护面排气格栅及车辆,通过设置在后侧围护面的安装孔内的格栅板,格栅板的泄压阀侧扣设有空腔结构的吸音架,吸音架的空腔结构外侧敷设有吸音棉,格栅板和吸音架分别通过设置在四角的塑料卡扣固定在后侧围护面的四周,从而可以能够有效抑制由于排气格栅与车身泄压阀互通,使得车辆的外部会通过泄压阀直接传递到乘员舱的噪音,从而提高整车的NVH品质。
