Combined type automobile exhaust pipe silencing structure and operating method thereof

Abstract

The invention discloses a combined type automobile exhaust pipe silencing structure. The structure comprises a silencer body and a regulating mechanism. The regulating mechanism is mounted at one endof the silencer body. The silencer body comprises a silencing shell, a first shell cover, an exhaust pipe, a second shell cover, a gas inlet pipe, first connecting rods, second connecting rods, firstconnecting sleeves, silencing pipes, silencing holes, acoustic materials, first limit blocks, first mounting clamp rings and first limit grooves. The outer side of one end of the silencing shell is sleeved with the first shell cover. The exhaust pipe is mounted on one side of the first shell cover. The outer side of the other end of the silencing shell is sleeved with the second shell cover. The gas inlet pipe is mounted on one side of the second shell cover. According to the combined type automobile exhaust pipe silencing structure provided by the invention, the first shell cover and the second shell cover are taken down from the two ends of the silencing shell, the acoustic materials inside are convenient to replace, the replacement cost of a silencer is lowered, in addition, practical operation and application are facilitated, a tail gas exhaust point can be increased conveniently, it is guaranteed that an automobile uses the silencing structure on a ponding road section, and the automobile is protected against damage of ponding water.

Description

technical field [0001] The invention relates to the field of automobile exhaust pipe silencer equipment, in particular to a combined automobile exhaust pipe silencer structure and an operation method thereof. Background technique [0002] The exhaust pipe is installed between the exhaust branch pipe of the engine and the muffler, so that the entire exhaust system is flexibly connected, so as to reduce vibration and noise, facilitate installation and prolong the life of the exhaust muffler system; For air ducts with noise transmission, noise reduction devices such as pipes with sound-absorbing linings and elbows, or pipes with sudden changes in cross-sectional area and other pipes with discontinuous acoustic impedance can be used to attenuate or reflect the noise in the pipe. The former is called a resistive muffler, the latter is called a resistive muffler, and there is also an impedance compound muffler. [0003] Existing automobile exhaust pipes use a sound-absorbing stru...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a combined type automobile exhaust pipe noise reduction structure and its operation method. When used, the sound-absorbing material will be full of smoke, oil and water vapor, resulting in poor sound-absorbing quality. It is necessary to disassemble and replace the sound-absorbing structure as a whole, which increases costs; at the same time, the existing sound-absorbing structure for the exhaust pipe is located at the bottom of the car. When the car is driving When passing through a waterlogged area, water will enter the muffler through the exhaust pipe, making the muffler unusable, and causing the car to break down in the waterlogged area, causing damage to the interior of the car in severe cases.
