The utility model discloses an air inlet, which is arranged between the front cabin of an automobile and the air conditioning box, including a tube body and a muffler tube. The muffler tube is arranged inside the tube body. The surface of the muffler tube is evenly provided with a muffler hole. The muffler tube is not in contact with the inner wall of the tube body. The muffler tube is fixedly connected with the inner wall of the body through a convex ring, and the convex ring is arranged in the muffler tube body. Near the end of the front compartment of an automobile, the pipe body is divided into a tapering pipe and a straight pipe. The tapering pipe is a tubular structure with a gradually enlarged orifice from the front compartment of the automobile to the air conditioning box. The straight pipe is a straight pipe. The straight pipe is arranged at a larger opening end of the tapering pipe and is connected with the tapering pipe. The muffler tube is not in contact with the inner wall of the tube, which greatly improves the muffling effect. By dividing the tube body into a tapered tube and a straight tube, when the flow rate of gas is inconvenient, the increase of cross section will reduce the flow rate of gas and further reduce the noise. The utility model also discloses an automobile adopting the aforementioned air inlet.

,特别是涉及一种进风道及汽车。
技术介绍
随着汽车工业的飞速发展和人们生活水平的提升,汽车已经成为人们出行、货运等不可或缺的交通工具之一。汽车的空调箱需进气和出气来实现制冷或制热,在进气过程中由于空气流速较大,会产生噪音,而进气道与汽车前舱连通,当汽车行驶时会产生更大的噪音。授权号CN102759186B公开了一种用于降低汽车空调风道噪声的装置及使用该装置的汽车空调风道,通过在风道内设置多孔消音管,实现了降低噪音的效果。现有技术中通过单一的多孔消音管来降噪,而消音管上的孔直接与风道的内壁接触,多孔消音管的消音过程需空气穿过消音孔才能实现,当消音孔与风道内壁直接接触时,能穿过消音孔的空气极少,达到的消音效果也较差。
技术实现思路
本技术的一个目的在于提出一种消音效果好的进风道。一种进风道,设置于汽车前舱和空调箱之间,包括管体和消音管,所述消音管设置于所述管体内部,所述消音管的表面均匀设有消音孔,所述消音管与所述管体内壁不接触,所述消音管通过凸环与所述管体的内壁固定连接,所述凸环设置于所述消音管的靠近汽车前舱的一端,所述管体分为渐 ...
