Description

A kind of noise reduction air inlet pipe of automobile air filter
Technical field
The utility model relates to auto-parts technical fields, more particularly to a kind of noise reduction air inlet pipe of automobile air filter.
Background technique
With the development of the automobile industry, people require the dynamic property, economy, NVH etc. of automobile higher and higher, while people Requirement to vehicle comfort it is also higher and higher, reduce noise and vibration, improve the weight that vehicle comfort has been auto industry Want research topic.Gas handling system is one of main noise source of automobile, and arrangement of the air inlet pipeline in enging cabin will be taken into account more Kind factor, is often difficult to combine the demand in compact engine cabin and air inlet pipe fluency, when air inlet pipeline air inlet has some setbacks When smooth, different degrees of inflow noise will be generated.
Utility model content
It in view of the above technical problems, should be into the purpose of the utility model is to provide a kind of noise reduction air inlet pipe of automobile air filter Tracheae can realize any bending, occupy little space, while its good muffling effect, simple production process, can overcome above-mentioned existing The deficiency of technology.
In order to achieve the above objectives, the technical solution that the utility model uses is: providing a kind of noise reduction of automobile air filter Air inlet pipe, including air inlet section and air outlet section, are attached between the air inlet section and air outlet section by spinnerule.
Preferably, the porosity value of the spinnerule is between 5%~60%.
Preferably, pass through rivet interlacement between the air inlet section and spinnerule.
Preferably, pass through rivet interlacement between the air outlet section and spinnerule.
Preferably, the air inlet section is the horn mouth with taper, and the bell-mouthed osculum and the spinnerule carry out Connection, the installation of the air inlet of the bell-mouthed big mouth vehicle body air-inlet grille.
Preferably, the air outlet section is bend pipe, and one end of the bend pipe connect with the spinnerule, the other end and air filter into Row connection installation.
Preferably, the cableties for fixing air inlet pipe are provided in the air outlet section.
Preferably, the air inlet section and the air outlet section pass through blow molding respectively.
The beneficial effects of the utility model are: 1, air inlet section and air outlet section connected by spinnerule, make noise reduction air inlet pipe can To realize larger angle rotation and bending, the installation requirements of different enging cabins are adapted to, and space occupied is small;2, spinnerule is more Pore structure has good erasure effect, reduces inflow noise;3, using blow molding air inlet section and air outlet section, structure is simple, at Type simple process, easy for installation and overall cost are low.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of one preferred embodiment of the utility model;
The components in the drawings are labeled as follows: 1, air inlet section, 2, spinnerule, 3, air outlet section, and 401,
One rivet, the 402, second rivet, 5, cableties.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear Define.
Referring to Fig. 1, the utility model embodiment includes:
A kind of noise reduction air inlet pipe of automobile air filter, including air inlet section 1 and air outlet section 3, the air inlet section 1 and air outlet section 3 it Between be attached by spinnerule 2, the air inlet section 1 is the horn mouth with taper, and the bell-mouthed osculum passes through first Rivet 401 is fixedly connected with the spinnerule 2, the installation of the air inlet of the bell-mouthed big mouth vehicle body air-inlet grille, it is described go out Gas section 3 is bend pipe, and one end of the bend pipe is fixedly connected by the second rivet 402 with the spinnerule 2, the other end and air filter into Row connection is installed, and the cableties 5 for fixing air inlet pipe, the air inlet section 1 and the air outlet section 3 are provided in the air outlet section 3 Pass through blow molding respectively.
The working principle of the present embodiment are as follows: 3 one end of air outlet section of noise reduction air inlet pipe and air filter are attached installation, air inlet Section 1 connect installation with the air inlet of vehicle body air-inlet grille, and air inlet pipe is fixed in enging cabin by cableties 5, this process Middle spinnerule 2 can be bent or be rotated as needed, and for air after the entrance of air inlet section 1, the porous structure of spinnerule 2 can be with It realizes the effect to the sound-deadening and noise-reducing of charge air flow, then air filter is vented to by air outlet section 3.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in Other related technical areas are also included in the patent protection scope of the utility model.
