Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides a device of making an uproar falls in car as shown in the figure, including falling the device body of making an uproar 5, automobile exhaust outlet duct 1 and automobile exhaust intake pipe 6, its characterized in that: the automobile exhaust outlet pipe 1 is hermetically connected with a noise reduction device body 5 through an outlet pipe fixing device 2, the outlet pipe fixing device 2 facilitates the regular replacement of an exhaust filter element 8 in the automobile exhaust outlet pipe 1, an exhaust filter element 8 is arranged in the automobile exhaust outlet pipe 1, the exhaust filter element 8 is used for filtering automobile exhaust and reducing the pollution of the automobile exhaust to air, a limit block 7 is arranged at the top end of the left side of the exhaust filter element 8, a vacuum layer 4 is arranged in the noise reduction device body 5, the vacuum layer 4 cuts off a medium transmitted by the air to reduce the diffusion of noise to the outside, a cotton sound absorption layer 3 is arranged on the inner side of the leftmost side of the vacuum layer 4, a first sound insulation plate 9 is arranged on the right side of the cotton sound absorption layer 3, a sound absorption plate 10 is arranged on the right side of the first sound insulation plate 9, and a second sound insulation plate 11 is arranged on the, second acoustic celotex board 11 right side is provided with buffer 12, cotton sound absorbing layer 3, first acoustic celotex board 9, second acoustic celotex board 11 and buffer 12 are used for the intensity to the absorption noise reduction of noise, realize the purpose of making an uproar falls to the noise.
Further, in the above technical solution, the outer side of the noise reduction device body 5 is sleeved with two hoops 13, the two hoops 13 are connected by a noise reduction device fixing frame 15, and the noise reduction device fixing frame 15 is provided with a noise reduction device fixing hole 15.
Furthermore, in the above technical solution, the right side encourage of the buffer device 12 has a semicircular groove, and the center of the groove and the center of the automobile exhaust inlet pipe 6 are on the same horizontal plane, so as to buffer noise and automobile exhaust and hinder the transmission of noise.
Further, in the above technical solution, the sound-absorbing plate 10 is foamed aluminum.
This practical theory of operation: firstly, the noise emitted by the automobile engine is transmitted to the interior of the noise reduction device body through the automobile exhaust inlet pipe along with the automobile exhaust, the buffer device on the same horizontal plane with the automobile exhaust inlet pipe has the function of buffering noise and exhaust, thereby weakening the intensity of the noise, then weakening the noise step by step through the second sound insulation board, the sound absorption board, the first sound insulation board and the cotton sound absorption layer, meanwhile, the vacuum layer arranged on the inner wall surface of the noise reduction device body can also reduce the noise diffusion, and finally the weakened weak sound is transmitted out along with the automobile exhaust through the automobile exhaust outlet pipe, but the noise intensity is greatly reduced, the influence to human being is very little, and the air filter who installs simultaneously in the automobile exhaust outlet pipe also can play filtration purification's effect to automobile exhaust, reduces the pollution of automobile exhaust to the air.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
