The invention relates to the technical field of automobile parts, and discloses an automobile exhaust pipe with a novel silencing structure. The automobile exhaust pipe comprises a shell, an exhaust inlet pipe connected with the exhaust pipe of an automobile is arranged in the shell and located at one end of the shell, silencing holes are formed in the part, located in the shell, of the exhaust inlet pipe, a containing box is arranged at the silencing holes in a covering mode, and the containing box is internally filled with a sound absorbing material; exhaust splitting pipes are symmetricallyarranged at the tail end of the exhaust inlet pipe, the exhaust splitting pipes extend to the other end of the shell, the exhaust splitting pipes are both connected with one ends of first sleeves, partition plates are arranged in the first sleeves at equal intervals along the axial direction of the first sleeves, and are arranged along the radial direction of the first sleeves, silencing pipes perpendicular to the partition plates are uniformly arranged on the partition plates along the circumferential direction of the partition plates, and the other ends of the first sleeves are connected with an exhaust outlet pipe; a fan is arranged in the part, located in the front end of the air inlet pipe, of the shell, and filter screens are both arranged at the two ends of the shell. The containing box, the exhaust splitting pipes and the first sleeves are arranged to be used for repeated silencing and noise reduction on automobile exhaust, so that the silencing effect of the automobile exhaust pipe is good.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to an auto exhaust pipe with a novel sound-absorbing structure. Background technique [0002] Automobile exhaust bellows, also known as automobile exhaust pipe hose, is installed in the exhaust pipe between the engine exhaust branch pipe and the muffler, so that the entire exhaust system is flexibly connected, thereby reducing vibration and noise, and is convenient. The function of installing and prolonging the life of the exhaust muffler system. With the increase of car ownership in cities, traffic noise has a greater impact on people's lives. Car noise interferes with people's normal life and rest, and even affects people's health in severe cases. Therefore, people have higher and higher requirements on the control of the noise of automobiles. [0003] The patent with the application number CN201620095746.X discloses a high-efficiency silencer automobile exhaust pipe, which ...
