本发明提供了一种汽车消音降噪排气系统,属于车辆技术领域,包括用于安装在侧围外板和C柱加强板之间的壳体,壳体的上部设有用于连通车内室的第一口部,壳体的下部设有用于连通排风口气帘的第二口部,壳体的内壁上设有吸音组件,壳体内腔设有阻尼隔板。本发明还提供了一种使用该汽车消音降噪排气系统的汽车。本发明提供的汽车消音降噪排气系统,车内室的气体通过第一口部经壳体内腔到达第二口部,通过风帘排出;同样的,室外噪音通过第二口部经壳体内腔到达第一口部,进入到车内室,在噪音传递过程中,噪音通过阻尼隔板及壳体内壁的阻挡,在壳体内腔形成二次衰减,同时利用吸音组件吸收噪音,从而最大限度的降低噪音,提高车内室的舒适度。

    The invention provides an automobile noise reduction and exhaust system, which belongs to the technical field of vehicles, and the system comprises a shell used for being mounted between a side wall outer plate and a C column reinforcing plate, the upper part of the shell is provided with a first opening part used for being communicated with an automobile inner chamber, the lower part of the shell is provided with a second opening part used for being communicated with an exhaust port air curtain, and the inner wall of the shell is provided with a sound absorption assembly. A damping partition plate is arranged in an inner cavity of the shell. The invention further provides an automobile using the automobile noise reduction and exhaust system. According to the automobile noise reduction and exhaust system, air in an automobile inner chamber reaches the second opening part through the inner cavity of the shell through the first opening part and is exhausted through the air curtain; similarly, outdoor noise reaches the first opening part through the inner cavity of the shell through the second opening part and enters the interior of the vehicle, in the noise transmission process, the noise is blocked by the damping partition plate and the inner wall of the shell, and secondary attenuation is formed in the inner cavity of the shell; meanwhile, the noise is absorbed through the sound absorption assembly, so that the noise is reduced to the maximum extent, and the comfort level of the interior of the vehicle is improved.
