Abstract
The utility model relates to the technical field of automobile spare parts, in particular to a noise-reduction automobile exhaust pipe. The noise-reduction automobile exhaust pipe comprises an exhaust pipe, and the exhaust pipe is divided into an upper connector, a lower connector and a barrel. The upper connector and the lower connector are in a funnel shape, and the exhaust pipe is provided with a plurality of sound eliminators and thin-wall liners. When the noise-reduction automobile exhaust pipe is used, the funnel-shaped upper connector and the funnel-shaped lower connector can lower noise caused during gas exhausting. In addition, the sound eliminators and the thin-wall liners can enable a noise-reduction function of the exhaust pipe to be further improved. The noise-reduction automobile exhaust pipe has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.
Description
Technical field
The utility model relates to the auto parts machinery technical field, particularly a kind of automobile exhaust pipe of noise reduction.
Background technique
Along with living standards of the people improve constantly, automobile has become the daily traffic tool, brought a lot of facilities for our life, but anything has dual character, and facility also will be paid a price, and that is exactly waste gas and the noise puzzlement of outlet pipe.
Automobile exhaust pipe is one of vitals in the automobile exhaust system, and existing automobile exhaust pipe only has an exhaust supervisor usually, but the exhaust supervisor does not have good decrease of noise functions usually.Become the in the industry focus of research so how to invent a kind of exhaust system simple in structure, that have denoising structure and long service life.
The model utility content
The purpose of this utility model is for the defective of prior art and deficiency, and automobile exhaust pipe a kind of simple in structure, reasonable in design, easy to use, noise reduction is provided.
For achieving the above object, the technical solution adopted in the utility model is:
The automobile exhaust pipe of a kind of noise reduction described in the utility model comprises outlet pipe, and described outlet pipe is divided into upper connection, lower contact and cylindrical shell three parts, and described upper connection and described lower contact are funnel-like, and described outlet pipe is provided with several silencing apparatuss and thin-walled inner bag.
Further, the outer wall of the port inner wall of described upper connection and lower contact and silencing apparatus closely cooperates.
Further, the internal surface of described silencing apparatus is provided with a plurality of grooves, and described groove is gust shape to be arranged, and the outer circle wall of described silencing apparatus is provided with puigging.
Further, the gap between the joint inner end of the inwall of described cylindrical shell and silencing apparatus is provided with the ring-type door closure.
Further, described puigging one end is butted on upper connection or lower contact mutually; The described puigging the other end is butted on the ring-type door closure mutually.
Further, described thin-walled inner bag is nested in the inwall of cylindrical shell, and it is spherical to be semicircle in the described thin-walled, is provided with a plurality of through holes in the described thin-walled inner bag.
After adopting said structure, the utility model beneficial effect is: the automobile exhaust pipe of a kind of noise reduction described in the utility model, comprise outlet pipe, described outlet pipe is divided into upper connection, lower contact and cylindrical shell three parts, described upper connection, lower contact are funnel-like, and described outlet pipe is provided with several silencing apparatuss and thin-walled inner bag.When using the utility model, be funnelform upper connection, noise diminished when lower contact can make exhaust; In addition, the setting of silencing apparatus and thin-walled inner bag can make the outlet pipe decrease of noise functions further strengthen.The utlity model has simple in structurely, arrange rationally, the advantage such as fabricating cost is low.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, 2, the automobile exhaust pipe of a kind of noise reduction described in the utility model, comprise outlet pipe 1, described outlet pipe 1 is divided into upper connection 11, lower contact 12 and cylindrical shell 13 3 parts, and described upper connection 11 and described lower contact 12 are the funnel-like setting, and the gas that can make High Temperature High Pressure enters in the larger cylindrical shell of volume 13 from the silencing apparatus 2 of small volume, pressure reduces, speed is slack-off, thereby effectively reduces the generation of noise, and described outlet pipe 1 is provided with several silencing apparatuss 2 and thin-walled inner bag 5.
The port inner wall of described upper connection 11 and lower contact 12 and the outer wall of silencing apparatus 2 closely cooperate.
The internal surface of described silencing apparatus 2 is provided with a plurality of grooves 21, and when gas entered the groove 21 of gust shape arrangement, gas can be subject to the absorption of groove 21, thus effective noise reduction function.
The outer circle wall of described silencing apparatus 2 is provided with puigging 22, and puigging 22 can adopt stainless silk screen and the cotton composition of high temperature, can get good soundproof effect like this.
Gap between the joint inner end 23 of the inwall of described cylindrical shell 13 and silencing apparatus 2 is provided with ring-type door closure 4, described puigging 22 1 ends are butted on upper connection 11 or lower contact 12 mutually, described puigging 22 the other ends are butted on ring-type door closure 4 mutually, can prevent effectively that like this puigging 22 and silencing apparatus 2 from relatively moving, and plays the fixedly effect of puigging 22.
Described thin-walled inner bag 5 is nested in the inwall of cylindrical shell 13, and it is spherical that described thin-walled inner bag 5 is semicircle, owing to be provided with a plurality of through holes 51 in the described thin-walled inner bag 5, pass through thereby hindered air-flow, and plays shunting action, also can effective noise reduction function.
During with the utility model discharging engine exhaust, not only can reduce noise by funnelform upper connection, lower contact; And can improve the outlet pipe decrease of noise functions by silencing apparatus and thin-walled inner bag.The utlity model has simple in structurely, arrange rationally, the advantage such as fabricating cost is low.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above only is preferred embodiments of the present utility model, thus all equivalence variation or modifications of doing according to the described structure of the utility model patent claim, feature and principle, all in the utility model patent claim.
