Description

A kind of tailpipe and automobile
Technical field
The utility model is related to technical field of automobile parts, is especially a kind of tailpipe and automobile.
Background technology
Automobile exhaust system refers to the system for collecting and discharging waste gas, and the gas extraction system generally includes exhaust manifold, row Tracheae, muffler, tail pipe etc..Automobile exhaust system has cleaning vehicle tail gas concurrently and reduces the function of discarded noise.Tailpipe Sound deadening capacity be gas extraction system sound deadening capacity important composition, improve tailpipe acoustical absorptivity, vehicle noise water can be reduced It is flat.However, the tailpipe generally existing of prior art is to reducing the less problem of vehicle noise contribution.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple structure, easy for installation, is not changing installation side Formula and on the premise of taking up room less, can effectively improve the noise elimination level of automobile exhaust system, reduce making an uproar for exhaust pipe mouth The tailpipe of sound level.
Technical solution of the present utility model is to provide a kind of tailpipe with following structure, including tail pipe sheet Body, wherein, also including Helmholtz silencer, Helmholtz silencer is connected with tail pipe body and communicates.
After using above structure, compared with prior art, the utility model has the advantages that:Simple structure, it is easy for installation, On the premise of not changing mounting means and taking up room less, the noise elimination level of automobile exhaust system can be effectively improved, reduced The noise level of exhaust pipe mouth.
Preferably, Helmholtz silencer can be two chamber Helmholtz silencers.
Preferably, two chamber Helmholtz silencers may include dividing plate, conduit and connecting tube, and dividing plate is arranged on Helmholtz To be separated into silencer and inside Helmholtz silencer the first Helmholtz chamber and the second Helmholtz chamber, conduit run through every Plate is used to connect the first Helmholtz chamber and the second Helmholtz chamber, and connecting tube one end is connected with the second Helmholtz chamber and communicates, Its other end is connected with tail pipe body and communicates.
Preferably, the first Helmholtz chamber and the second Helmholtz chamber can be cylindrical cavity, its cavity volume according to Need depending on the noise frequency for solving, dividing plate can be a plate for circle.
Preferably, connecting tube two ends can be connected phase with the second Helmholtz chamber and tail pipe body respectively by welding manner It is logical.
Preferably, conduit can be a pipe, and can be fixed by welding manner with dividing plate.
The utility model additionally provides a kind of automobile, and the automobile has the tailpipe of said structure.
Brief description of the drawings
Fig. 1 is the structural representation of the automobile exhaust system using the utility model tailpipe;
Fig. 2 is the structural representation of two chamber Helmholtz silencers in the utility model.
Specific embodiment
With reference to the accompanying drawings and detailed description to a kind of tailpipe of the utility model and automobile further specifically It is bright:
As depicted in figs. 1 and 2, a kind of tailpipe of the utility model includes tail pipe body 1 and Helmholtz silencer 2. In this embodiment, Helmholtz silencer 2 uses two chamber Helmholtz silencers, the conspicuous nurse of this two chamber Hereby silencer includes dividing plate 201, conduit 202 and connecting tube 203 suddenly, and dividing plate 201 is arranged in Helmholtz silencer 2 and will be conspicuous The first Helmholtz chamber 204 and the second Helmholtz chamber 205, the first Helmholtz chamber 204 are separated into inside Mu Huozi silencers 2 Positioned at the top of the second Helmholtz chamber 205.One Helmholtz silencer of chamber only for a CF and its near The noise of frequency band, the Helmholtz silencer of two chambers can eliminate two noises of frequency band, and the utility model is by using Two chamber Helmholtz silencers, can disposably solve two different frequency noise problems.
In this embodiment, the central position of dividing plate 201 has a circular hole (not shown), and the circular hole is used In conduit 204 is installed, conduit 204 is fixed with welding manner after dividing plate 201 by the circular hole with dividing plate 201, conduit 204 Effect is for connecting the first Helmholtz chamber 204 and the second Helmholtz chamber 205.First Helmholtz chamber 204 and second hertz Mu Huozi chambers 205 are cylindrical cavity, and dividing plate 201 is a plate for circle.First Helmholtz chamber 204 and second hertz of nurse Depending on the noise frequency that hereby volume in chamber 205 is solved as needed suddenly, general volume is bigger, and soluble noise frequency is got over Greatly, the ration of division of two chambers is different, and soluble noise problem is also different, so that the utility model can be with specific aim The tail pipe noise of different frequency is reduced, but the volume in Helmholtz chamber is limited to chassis installing space.
In this embodiment, the two ends of connecting tube 203 be by welding manner respectively with the second Helmholtz chamber 205 and tail pipe body 1 connection communicate.
In this embodiment, the cavity of Helmholtz silencer 2, dividing plate 201 and connecting tube 203 are steel system Into.
This specific embodiment also discloses a kind of automobile, and the automobile includes the tailpipe with above architectural feature.
Embodiments described above is only that preferred embodiment of the present utility model is described, not to this reality It is defined with new scope, on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art couple Various modifications and improvement that the technical solution of the utility model is made, all should fall into the guarantor of the utility model claims determination In the range of shield.
