Abstract

The invention discloses an automobile exhaust noise-abatement device. The device comprises a tail gas pipe and an air outlet pipe, and a first groove is formed in the upper portion of the interior ofthe tail gas pipe; a flat pipe is arranged on the left side of the interior of a water cooling pipe, and a second groove is formed in the middle of the interior of the flat pipe; a baffle is arrangedon the left side of a medicine box, and a clamping column is arranged on the left side of the baffle; a curved pipe is arranged on the right side of the interior of the water cooling pipe, and a silencing device is arranged inside the curved pipe; and a hole pipe is arranged inside the silencing device, and a first acoustic insulation board is arranged in the upper portion of the interior of the hole pipe; and the hole pipe is arranged on the left side of the air outlet pipe, and silencing cotton is arranged on the inner surface of the air outlet pipe. According to the automobile exhaust noise-abatement device, detaching is convenient, time and labor are relatively saved, the tail gas can be cooled, the situation that the service life of the noise-abatement device is influenced due to toohigh temperature is avoided, purification treatment can be carried out on the automobile exhaust at the same time, damage to the silencing device can be avoided, and vibration can be buffered.

Description

technical field [0001] The invention relates to the technical field of automobile noise reduction devices, in particular to an automobile exhaust noise reduction device. Background technique [0002] Noise refers to the sound emitted by the sounding body when it vibrates irregularly. The sound is generated by the vibration of the object and propagates in a certain medium (such as solid, liquid, gas) in the form of waves. Nowadays, due to the rapid increase in the number of motor vehicles , so that traffic noise becomes the main noise source in the city. Long-term exposure to noise-filled environments can easily cause great harm to the human body. Therefore, noise reduction devices are becoming more and more important. Although there are many noise reduction devices on the market, there are still Many shortcomings, such as inconvenient disassembly, time-consuming and labor-intensive, unable to cool the exhaust gas, too high temperature will easily affect the service life of t...
