Specific embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.Below with reference to accompanying drawing
The embodiment of description is exemplary, it is intended to for explaining the present invention, and be not considered as limiting the invention.
Describe muffler assembly 100 according to embodiments of the present invention in detail below in conjunction with the accompanying drawings.Muffler assembly 100 can be applied
With the exhaust noise of reduction vehicle in gas extraction system.Or muffler assembly 100 can be applied in gas handling system to reduce
The inflow noise of vehicle.
Muffler assembly 100 according to embodiments of the present invention can include：Muffler body 10 and intubation 20.Such as Fig. 1 and Tu
Shown in 3, muffler body 10 has central passage 11, and muffler body 10 is interior to be formed with silencing cavity 12, and muffler
First through hole 13 is provided with the inner peripheral surface of body.With reference to shown in Fig. 1 and Fig. 2, in the centrally disposed passage 11 of intubation 20,
Be provided with the second through hole 21 in intubation 20, the relative position of muffler body 10 of intubation 20 is adjustable with change first through hole 13 with
The overlapping area of the second through hole 21.
Alternatively, as shown in figures 1 and 3, first through hole 13 is uniform on the length direction and circumference of muffler body 10
Distribution, as shown in Figure 2 and Figure 5, the second through hole 21 is uniformly distributed on the length direction and circumference of intubation 20, wherein,
The quantity of first through hole 13 can be with identical with the quantity of the second through hole 21, the aperture of first through hole 13 and the second through hole
21 aperture can be with identical.
Wherein, muffler assembly 100 can be applied in the gas extraction system of vehicle, and intubation 20 can be with the row in gas extraction system
Tracheae is (not shown) to be connected.The waste gas of vehicle discharge can enter into intubation 20 in muffler assembly 100 by blast pipe
It is interior, and waste gas can flow along the length direction (left and right directions i.e. shown in Fig. 2) of intubation 20, and then waste gas can be with
Entered into silencing cavity 12 by the overlapping region of the through hole 21 of first through hole 13 and second, eventually pass the noise reduction of silencing cavity 12
Waste gas discharge afterwards is to the external world.
And, muffler assembly 100 can be applied in the gas handling system of vehicle, intubation 20 can with gas handling system in
Air inlet pipe is (not shown) to be connected.The air of vehicle inspiration can enter into intubation in muffler assembly 100 by air inlet pipe
In 20, and air can flow along the length direction (left and right directions i.e. shown in Fig. 2) of intubation 20, then air
Can be entered into silencing cavity 12 by the overlapping region of the through hole 21 of first through hole 13 and second, eventually pass silencing cavity 12
Air after noise reduction is discharged into engine.
Muffler assembly 100 is identical with the operation principle in gas extraction system in the gas handling system of vehicle, specific as follows：By changing
Become the position of muffler body 10, thus it is possible to vary the overlapping area of the through hole 21 of first through hole 13 and second.When overlapping area is got over
When big, the frequency of noise elimination of muffler assembly 100 is bigger, when overlapping area gets over hour, the frequency of noise elimination of muffler assembly 100
It is less.Thus, muffler body 10 can be by changing the frequency of noise elimination of itself to abate the noise, such that it is able to reduce exhaust

70, control unit 70 is electrically connected with according to crankshaft rotational speed sensor respectively with crankshaft rotational speed sensor 60 and motor 30
The rotating speed of the bent axle of 60 detections controls the working condition of motor 30.Wherein, when speed of crankshaft changes, air inlet
Inflow noise in system correspondingly changes, and the frequency noise in gas extraction system also can correspondingly change, and control is single
Unit 70 can draw the frequency noise in gas handling system and gas extraction system according to the change of speed of crankshaft, so as to control unit 70
The overlapping area that motor 30 changes the through hole 21 of first through hole 13 and second by transmission mechanism can be controlled, is changed and is eliminated the noise
The frequency of noise elimination of device assembly 100 so that the frequency noise of the frequency of noise elimination of muffler assembly 100 and corresponding gas extraction system or
The frequency noise of person's gas handling system matches, and then muffler assembly 100 can be caused to realize the purpose eliminated the noise.Alternatively,
Control unit 70 can be single-chip microcomputer.
As shown in fig. 7, when the engine speed of vehicle is respectively 2000rpm, 2500rpm and 3500rpm, air inlet system
System generates more obvious roar, and the roar at several places is drawn by the radiated noise of 125Hz, 170Hz and 260Hz
Rise, the noise in the frequency range can be eliminated using muffler assembly 100 according to embodiments of the present invention, pass through
It is corresponding to calculate, when the overlapping area of the through hole 21 of first through hole 13 and second is 4.5mm2When, the muffler assembly 100
Frequency of noise elimination is 125Hz, when the overlapping area of the through hole 21 of first through hole 13 and second is 5.3mm2When, the muffler assembly
100 frequency of noise elimination is 170Hz, when the overlapping area of the through hole 21 of first through hole 13 and second is 6.8mm2When, the silencer
The frequency of noise elimination of component 100 is 260Hz.
Jing after the silencer is installed in test, the radiated noise of 125Hz, 170Hz and 260Hz that gas handling system is produced can be by
Effectively eliminate, thus, it is possible to illustrate under the conditions of engine different rotating speeds, muffler assembly 100 according to embodiments of the present invention
The noise of the different frequency of gas handling system generation can be eliminated, and effect is obvious.
Muffler assembly 100 according to embodiments of the present invention, the position by intubation 20 and muffler body 10 is adjustable, so as to
The overlapping area of the through hole 21 of first through hole 13 and second can be changed, the frequency of noise elimination that can cause muffler assembly 100 changes
Become to match with corresponding gas extraction system or the frequency noise in gas handling system, and then muffler assembly 100 can be caused to disappear
