Description
Technical field
The present invention relates to technical field of automobile parts, more particularly to a kind of muffler structure.
Background technology
Muffler is to allow air-flow by the way that but and can prevents or reduced a kind of device of sound transmission, is to eliminate air to move
The important measures of power noise.Muffler can stop the propagation of sound wave, it is allowed to which air-flow is by being the effective work for controlling noise
Tool.Muffler species is a lot, but studies carefully its noise elimination mechanism, it can be divided into six kinds of main types again, i.e. resistive muffler, anti-
Property muffler, impedance complex formula muffler, microperforated panel muffler, aperture muffler and active muffler.Existing muffler
Erasure effect is poor, needs further to be improved.
The content of the invention
The present invention is in order to overcome deficiency of the prior art, there is provided a kind of muffler structure.
The present invention is to be achieved through the following technical solutions：
A kind of muffler structure, including muffler shell, the side of the muffler shell are provided with sound gobo A, institute
The opposite side for stating muffler shell is provided with sound gobo B, the muffler shell be internally provided with short connecting plate A, tiltedly
Acoustical panel A, long connecting plate A, oblique acoustical panel B, long connecting plate B, oblique acoustical panel B, short connecting plate B, tiltedly opened described on acoustical panel A
Provided with through hole A, through hole B tiltedly is offered on acoustical panel B described, tiltedly through hole C is offered on acoustical panel B described, and described
Muffler shell is internally provided with L-type support member A and L-type support member B, and the L-type support member A's and L-type support member B
Side is provided with hush pipe, and bloop is offered in the outer surface of the hush pipe.
As the preferred technical solution of the present invention, the short connecting plate A, oblique acoustical panel A, long connecting plate A, oblique acoustical panel B,
Long connecting plate B, oblique acoustical panel B, short connecting plate B connect it from beginning to end successively, and are all made of using sound-absorbing material.
As the preferred technical solution of the present invention, the short connecting plate A and short connecting plate B are arranged on the muffler shell
Inwall on；The long connecting plate A and long connecting plate B is arranged on the inwall of the muffler shell.
As the preferred technical solution of the present invention, the through hole A, through hole B and through hole C sizes are identical.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention is made using abatvoix, due to frictional force
With the effect of resistance so that a part of acoustic energy is converted into thermal energy consumption and dissipated, so as to reach the purpose of noise elimination.
