Abstract

The invention discloses a car exhaust pipe device capable of reducing noise. The car exhaust pipe device capable of reducing noise comprises a barrel body, an upper joint, a lower joint, an entrance muffler, an exit muffler and thin-wall inner containers; the entrance muffler penetrates the inner part of the barrel body from the entrance of the upper joint; the exit muffler penetrates the inner part of the barrel body from the entrance of the lower joint; the thin-wall inner containers are staggered sequentially inside the barrel body; the thin-wall inner containers are connected with the barrel body respectively by virtue of baffles. The thin-wall inner containers are staggered inside the barrel body, and bulges are arranged on the inner wall of the barrel body, so that airflow movement is changed efficiently, and good noise reduction effect is realized; meanwhile, the muffler structures are arranged on the two ends, so that the noise reduction function is further enhanced; the thin-wall inner containers are made of a stainless steel material, so that the service life of the exhaust pipe can be prolonged.

Description

technical field [0001] The invention relates to a noise reduction automobile exhaust pipe device, which belongs to the technical field of automobile accessories. Background technique [0002] The exhaust pipe of a car has always been one of the main sources of vehicle noise. The noise is generally produced by the instability of high-speed air flow. The flowing air flow has the characteristics of high temperature, high pressure, and high speed. The emitted noise has high intensity, wide spectrum and wide range, which seriously affects the health of drivers and passengers. and the production and life of residents. [0003] The authorized announcement number is CN 202673424 U, which discloses a noise-reducing automobile exhaust pipe. It is equipped with a thin-walled inner tank and a muffler to achieve a certain noise-reducing effect. However, due to the number and position of the thin-walled inner tank It is not suitable, so that the exhaust pipe of the car does not achieve ...
