In a specific embodiment, air inlet drainage tube provided by the utility model, including rear end and engine charge
The main pipe 11 of mouth connection, the middle part of main pipe 11 are communicated with branch pipe 12, and the end of branch pipe 12 is communicated with resonant cavity 121.
In the course of work, resonant cavity 121 can be to the sound of the noise entered in the air inlet drainage tube as noise elimination original part
Wave is effectively offset, to eliminate the noise to induction noise, and then the operating noise of entire gas handling system is effectively reduced, and is guaranteed
The whole NVH performance of gas handling system and vehicle.
It should be pointed out that the volume of resonant cavity 121 is preferably 2L, specific in practical application to fully ensure that air-flow
Buffering needs, and suitably reduces the overall volume of the air inlet drainage tube.
Further, the rear end of main pipe 11 has bellows segment 13, is provided in bellows segment 13 several along main pipe 11
Extending direction successively uniformly distributed ripple struction 131.The bellows segment 13 can effectively avoid the vibration at engine from being transferred to institute
At the main structure for stating air inlet drainage tube, to avoid the components such as main pipe 11 and branch pipe 12 from damaging because of vibration, and further
Improve the integral vibration damping anti-acoustic capability of the air inlet drainage tube.
Specifically, the quantity of ripple struction 131 is 5.The arrangement of multiple ripple structions 131 can further increase ripple
The damping cushion effect of section 13.Certainly, the quantity of ripple struction 131 is not limited to described above 5, work in practical application
Making personnel can need to be adjusted flexibly according to actual condition the quantity of ripple struction 131, in principle, as long as can satisfy described
The actual use of air inlet drainage tube needs.
More specifically, the radial thickness of bellows segment 13 is 0.8mm.The thickness can be in the vibration damping for guaranteeing bellows segment 13
While buffering effect, its size of components is effectively reduced, keeps its modular construction more compact.Certainly, the radial direction of the bellows segment 13
Thickness is not limited to 0.8mm described above, and in practical application, the radial thickness of bellows segment 13 can need spirit according to operating condition
Adjustment living, in principle, as long as the actual use that can satisfy the air inlet drainage tube needs.
In addition, main pipe 11, branch pipe 12 and resonant cavity 121 are an integral structure.Specific in practical application, above-mentioned master
Tube body 11, branch pipe 12 and resonant cavity 121 are integrated blow molded construction, in the manufacturing process to make the air inlet drainage tube
Without individually arranging the molding die of resonant cavity, to effectively be dropped while guaranteeing the working performance of the air inlet drainage tube
Low its fabricates cost and technology difficulty.
On the other hand, stiffening plate 122 is connected between the outer wall of resonant cavity 121 and the outer wall of main pipe 11.The stiffening plate 122
It can effectively ensure that the physical fit and bonding strength between resonant cavity 121 and main pipe 11, improve 11 resonant cavity of main pipe
121 collaboration vibration and noise reducing ability, and the overall structure reliability of the air inlet drainage tube and its NVH performance is enable accordingly to mention
It is high.
In addition, being provided with link block 111 on the front end outer wall of main pipe 11, main pipe 11 is by running through link block 111
Bolt connection vehicle body on.This kind of bolt assembling structure is simple and reliable and easy to operate, meanwhile, bolt is assemblied in link block
It can be avoided influence of the bolt fastening structure to 11 main structure of main pipe on 111, avoid constructive interference, guarantee main pipe 11
Stability and high efficiency work.
Further, there is diversion section 112 at the front port of main pipe 11, diversion section 112 it is interior without leave front to back gradually
It is decreased to consistent with the internal diameter of main pipe 11.The diversion section 112 can effectively improve the intake efficiency of 11 inlet end of main pipe, and
Implement preliminary water conservancy diversion to charge air flow, to further avoid generating gas shock after gas enters main pipe 11, thus into one
Step reduces the operating noise of the air inlet drainage tube.
The buckle 113 being adapted to is clamped with air filter of engine in addition, having on outer wall at the rear port of main pipe 11.It should
Clamping connection between buckle 113 and air filter can effectively ensure that assembly intensity and company between the air inlet drainage tube and engine
Connect reliability.
More specifically, the inner wall of each corner of main pipe 11 and branch pipe 12 seamlessly transits.Seamlessly transitting structure can
The gas shock of each corner is further decreased, and then noise caused by avoiding because of gas shock, so that the air inlet be made to drain
The overall work noise of pipe accordingly reduces, and further increases the whole NVH performance of gas handling system and vehicle.It needs to illustrate
, in practical application, which is preferably arc transition.
In a specific embodiment, vehicle provided by the utility model, including car body and engine are set in the car body
It is equipped with the air inlet drainage tube air inlet drainage tube with engine cooperation, which is specially air inlet drainage as described above
Pipe.The air inlet drainage tube of the vehicle can be effectively reduced the operating noise of gas handling system, improve vehicle entirety NVH performance.
In summary, the air inlet drainage tube provided in the utility model, in the course of work, resonant cavity is as noise elimination original part
