For one of ordinary skill in the art, above-mentioned term concrete meaning in the present invention can be as the case may be understood.
The muffler assembly 100 of the embodiment of the present invention is described in detail with reference to Fig. 1 to Fig. 4.
Muffler assembly 100 according to embodiments of the present invention can include that muffler body 110, intubation 120, first are axially fixed
The axial positioning structure 140 of bit architecture 130 and second.
Muffler body 110 has central passage, and muffler body 110 includes internal perisporium and periphery wall, and internal perisporium is limited
Central passage, periphery wall is limited with internal perisporium and be provided with first in silencing cavity 101, and the internal perisporium of muffler body 110
Through hole 102, noise can be entered into silencing cavity 101 by first through hole 102, and is interfered in silencing cavity 101
To weaken the sound intensity, the purpose for reducing noise is reached.
Intubation 120 is the direct exclusion passage of vehicle exhaust, in the centrally disposed passage of intubation 120, is set in intubation 120
There is the second through hole 103, it is rotatable to change first through hole 102 and second that intubation 120 is configured to relative muffler body 110
The overlapping area of through hole 103.
The overlapping area of the through hole 103 of first through hole 102 and second can directly affect the frequency of noise elimination of muffler assembly 100,
The overlapping area of the through hole 103 of first through hole 102 and second is bigger, and the frequency of noise elimination of muffler assembly 100 is bigger；First leads to
The overlapping area of the through hole 103 of hole 102 and second is smaller, and the frequency of noise elimination of muffler assembly 100 is smaller.
Change the through hole 103 of first through hole 102 and second by changing the relative position of intubation 120 and muffler body 110
Overlapping area, and then the frequency of noise elimination of muffler assembly 100 can be changed so that muffler assembly 100 is adapted to many
Vehicle is planted, with stronger versatility.
Muffler assembly 100 according to embodiments of the present invention, can just be changed by rotating muffler body 110 or intubation 120
The overlapping area of the through hole 103 of first through hole 102 and second, and then change the frequency of noise elimination of muffler assembly 100, so as to disappear
Sound device assembly 100 is suitable for various different types of vehicles, improves the versatility of muffler assembly 100.
In some embodiments of the invention, as shown in Figures 1 to 4, the first axial positioning structure 130 is arranged on silencer
On body 110 and the second axial positioning structure 140 is arranged in intubation 120, the first axial positioning structure 130 and the second axle
Coordinate to location structure 140 carries out axially position with to muffler body 110 and intubation 120.
Thus, it is possible to ensure that the through hole 103 of first through hole 102 and second can overlap in the axial direction, as long as rotating silencer sheet
Body 110 or intubation 120, it is possible to so that the overlapping area of the through hole 103 of first through hole 102 and second changes, operation
Simply, conveniently.
In some embodiments of the invention, as shown in Figures 2 to 4, the second axial positioning structure 140 is configured to be arranged on
On the outer peripheral face of intubation 120 and circumferentially distributed first raised, the first axial positioning structure 130 is configured to and first axially
The second projection that location structure 130 coordinates.
After the first projection with the second male cooperation, show that the through hole 103 of first through hole 102 and second is completed in the axial direction fixed
Position, as long as rotating muffler body 110 or intubation 120 can just change the coincidence of the through hole 103 of first through hole 102 and second
Area.
Preferably, as shown in figure 4, muffler assembly 100 also includes fastener 150, in the through hole of first through hole 102 and second
After 103 overlapping area determines, fastener 150 wears the first axial positioning structure 130 and the second axial positioning structure 140
Fixed with by intubation 120 and muffler body 110 so that intubation 120 and muffler body 110 will not relatively rotate.
Specifically, circumferentially distributed Long Circle hole, the second axial direction positioning device are provided with the first axial positioning structure 130
On be provided with circular port, Long Circle hole and circular port when muffler body 110 and intubation 120 relatively rotate all the time just
It is right, after the overlapping area of the through hole 103 of first through hole 102 and second determines, fastener 150 can through Long Circle hole and
Circular port is fixed together with by muffler body 110 and intubation 120.Alternatively, fastener 150 is threaded fastener (example
Such as, wing bolt).
In some embodiments of the invention, as shown in Figure 1 to Figure 3, first through hole 102 is multigroup, and every group includes multiple
Multiple first through hole 102 in first through hole 102, and every group are circumferentially distributed, and multigroup first through hole 102 is axially distributed；
Second through hole 103 is multigroup, and every group includes multiple second through holes 103, and multiple second through holes 103 in every group are circumferentially
Distribution, multigroup second through hole 103 is axially distributed.
Thus, during noise can be evenly into silencing cavity 101, muffler assembly 100 is at least improve to a certain extent
Acoustical absorptivity.
Alternatively, as shown in figure 3, being additionally provided with multiple dividing plates 111 in silencing cavity 101, multiple dividing plates 111 are by silencing cavity
101 are separated into multiple noise reduction units 104.Wherein, each noise reduction unit 104 can correspond to multiple first through hole 102 and the
Two through holes 103, for example, in specific example of the invention, each noise reduction unit 104 one group of He of first through hole 102 of correspondence
One group of second through hole 103.
In some embodiments of the invention, be provided with intubation 120 or/and muffler body 110 make first through hole 102 with
The circumferential positioning structure that second through hole 103 overlaps in circumferential direction.In other words, circumferential positioning structure can cause intubation 120
Relatively rotated in certain scope with muffler body 110, or operator can be allowed to understand first through hole 102 and second
The overlapping area substantially of through hole 103.
Specifically, circumferential positioning structure includes the first circumferential positioning structure (not shown) being arranged on muffler body 110
With the second circumferential positioning structure (not shown) being arranged in intubation 120, it is circumferentially positioned in the first circumferential positioning structure and second
During respective outer side edges, the overlapping area of the through hole 103 of first through hole 102 and second is maximum.
Thus, operator can substantially understand the overlapping area of the through hole 103 of first through hole 102 and second, and then can adjust
The frequency of noise elimination of muffler assembly 100.
Preferably, the muffler assembly 100 of the embodiment of the present invention can also be included for showing that first through hole 102 and second is led to
First indication piece and the second indication piece of the overlapping area in hole 103, one of setting of the first indication piece and the second indication piece
On the first axial positioning structure 130, another of the first indication piece and the second indication piece are arranged on the second axial positioning structure
On 140.
Thus, user can overlapping area that is more directly perceived, knowing precisely the through hole 103 of first through hole 102 and second, side
Just it is used to be adjusted muffler body 110 and intubation 120.Alternatively, the first indication piece can be pointer and dial plate
One of them, the second indication piece is another of pointer or dial plate.
It is, of course, understood that the first indication piece and the second indication piece can also be separately positioned on the He of muffler body 110
In intubation 120.
