Pipe, for being connected with the air filter of place vehicle.
Further, the embodiment for providing according to this utility model, between wherein described air inlet pipe and connecting tube
Coordinate for zero clearance.
Further, the embodiment for providing according to this utility model, between wherein described air inlet pipe and connecting tube
Mating surface arrange fluted and projection, for play a part of spacing and prevent abjection.
Relative to prior art, the beneficial effects of the utility model include described below.
（1）By arranging porous material layer in the air inlet inside pipe wall, as its own material behavior can be effectively eliminated
Electromotor is transmitted through the Kuanping Terrane for coming, while which is also not take up too many space, will not reduce air inlet pipeline internal diameter, it is ensured that air-flow is suitable
Freely.
（2）One layer of waterproof cloth is wrapped outside the air inlet pipe, to completely cut off the rainwater of outside.
（3）Increase support between the waterproof cloth and air inlet pipe, the hypertonic motion of the waterproof cloth can be reduced, reduced which and produced
Raw abnormal sound；Meanwhile, the support increases the space between the waterproof cloth and air inlet pipe so that the porous material is constituted
The erasure effect of noise reduction layer is more preferable.

Specific embodiment
Below with reference to drawings and Examples, a kind of technical scheme of automotive air intake pipe that this utility model is provided is made into
The detailed description of one step.
Refer to shown in Fig. 1, a kind of automotive air intake provided according to an embodiment of the present utility model is provided
Pipe, which includes waterproof cloth 1, air inlet pipe upper shell 2, noise reduction layer 3, air inlet pipe lower house 4, support 5, band 6,7 and of connecting tube upper casing
Connecting tube lower casing 8.
Wherein, the air inlet pipe upper shell 2 is connected by snap with lower house 4, the air inlet 41 of the air inlet pipe
It is structure as a whole with the lower house 4.Cellular grille structure of the middle part of the complete housing for hollow out, the grille structure
Inner surface be respectively pasted with one layer of noise reduction layer 3 being made up of porous material.
Wherein described porous material is a kind of by the network structure material being mutually communicated or cap holes is constituted, and noise is passed through
Aperture on porous material is interfered and is reflected, so as to reach the purpose of noise elimination.In a specific embodiment, wherein described
