Problems solved by technology

At present, the power engine of most automobiles is an internal combustion engine. When the internal combustion engine is working, it will release a large amount of high-temperature exhaust gas, and the automobile will also generate huge noise during operation. However, the heat insulation effect of the exhaust pipe is poor, which brings inconvenience to customers and affects people's daily life. Life

Abstract

The invention discloses a low-noise automobile exhaust pipe device. The low-noise automobile exhaust pipe device comprises a rotating plate, wherein a first noise reduction device and a second noise reduction device are mounted on the rotating plate; a protecting shell sleeves the outer wall of the first noise reduction device; a sound absorbing layer is arranged between the outer wall of the first noise reduction device and the protecting shell; the first noise reduction device comprises a retractable rod; the top of the retractable rod is fixedly connected with a positioning device; a heat insulating layer is arranged on a side wall of the positioning device; pressure springs are uniformly distributed between the positioning device and the heat insulating layer; the top of the positioning device is fixedly connected with a connecting rod; a rotating device is arranged inside the connecting rod; a connecting hole is formed in the rotating device; and a buffer layer is arranged above the connecting hole. By the low-noise automobile exhaust pipe device, noises of an exhaust pipe are reduced effectively, the exhaust pipe can be fixed firmly and cannot drop easily, and pedestrians can be prevented from being scalded by the exhaust pipe to a certain degree.

Description

technical field [0001] The invention relates to the technical field of automobile exhaust pipes, in particular to a low-noise automobile exhaust pipe device. Background technique [0002] With the development of science and the progress of society, modern equipment is gradually entering people's lives. Modern equipment not only makes people's life more convenient, but also promotes the progress of human society. [0003] With the continuous development of my country's economy, motor vehicles have become very popular, and automobiles have entered thousands of households, and motor vehicles are also widely used in industry and agriculture. At present, the power engine of most automobiles is an internal combustion engine. When the internal combustion engine is working, it will release a large amount of high-temperature exhaust gas, and the automobile will also generate huge noise during operation. However, the heat insulation effect of the exhaust pipe is poor, which brings inc...
