Abstract
The utility model relates to a kind of air filter for automobile, comprise lower shell body, the top of described lower shell body is provided with upper shell by latch structure and clamp, the inside of described upper shell and lower shell body is provided with filter core, described lower shell body one end is provided with dividing plate, in the middle part of described dividing plate, regulating valve is installed, between described dividing plate and lower shell body, forms adjustable cavity.The utility model compact structure, rationally, filtering efficiency is high, the design of adjustable cavity, according to actual induction air flow ratio, valve opening can be adjusted thus changes air-strainer overall volume, to reach minimizing air pressure fluctuation, improve air inlet effect, reduce the object of induction noise.
Description
Technical field
The utility model relates to filter cleaner technical field, especially a kind of volume adjustable air filter for automobile for air inlet system for vehicle.
Background technique
Air-strainer is as the main parts size of automobile air inlet system, and its requirement provides clean, dry air to motor, and filtering efficiency is high, not for air flowing increases too much resistance.During engine running, intake process is interrupted, and air can be caused thus to vibrate in air filter housing.If air pressure fluctuation is excessive, engine charge effect can be affected, and can induction noise be strengthened.
At present, traditional air-strainer does not design adjustable cavity structure, air filter housing inner air pressure may be caused like this to fluctuate excessive, and air flow field is unstable, even produces turbulent flow, affects air inflow, and then affect engine performance.In addition, excessive air pressure fluctuation also can produce larger inflow noise, affects car load NVH performance.
Model utility content
The applicant, for the shortcoming in above-mentioned existing production technology, provides a kind of air filter for automobile rational in infrastructure, thus is conducive to improving air inlet effect, reduces inflow noise.
The technological scheme that the utility model adopts is as follows:
A kind of air filter for automobile, comprise lower shell body, the top of described lower shell body is provided with upper shell by latch structure and clamp, the inside of described upper shell and lower shell body is provided with filter core, described lower shell body one end is provided with dividing plate, in the middle part of described dividing plate, regulating valve is installed, between described dividing plate and lower shell body, forms adjustable cavity.
Further improvement as technique scheme:
Described lower shell body shape structure at a right angle.
The beneficial effects of the utility model are as follows:
The utility model compact structure, rationally, filtering efficiency is high, the design of adjustable cavity, according to actual induction air flow ratio, valve opening can be adjusted thus changes air-strainer overall volume, to reach minimizing air pressure fluctuation, improve air inlet effect, reduce the object of induction noise.Adjustable cavity described in the utility model, according to " quarter-wave long tube " principle design, to reduce resonance, reduces noise.
Because air-strainer itself has resonant cavity function, the situation that additionally cannot increase resonant cavity because motor front deck arrangement space is not enough effectively can be avoided.And can according to motor actual conditions, adjustment air cleaner volume, reduces air pressure fluctuation, improves air inlet effect.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
As shown in Figure 1, Figure 2 and Figure 3, the air filter for automobile of the present embodiment, comprise lower shell body 4, the top of lower shell body 4 is provided with upper shell 1 by latch structure and clamp 3, the inside of upper shell 1 and lower shell body 4 is provided with filter core 2, lower shell body 4 one end is provided with dividing plate 5, is provided with regulating valve 6 in the middle part of dividing plate 5, forms adjustable cavity 7 between dividing plate 5 and lower shell body 4.
Lower shell body 4 shape structure at a right angle.During practical application, according to the lower shell body 4 of the situation design different structure of overall free space.
The utility model is used for the air-strainer of air inlet system for vehicle, and this air-strainer comprises upper shell 1, filter core 2, lower shell body 4, clamp 3.During as installed, be arranged in lower shell body 4 by filter core 2, then inserted in the pin-and-hole in lower shell body 4 by the bearing pin in upper shell 1, finally by clamp 3 by upper shell 1, filter core 2, lower shell body 4 is fixed together, and completes assembling.Adjustable cavity 7 and regulating valve 6 are all arranged in lower shell body 4.Realization improves air inlet effect, reduces the function of inflow noise.
More than describing is to explanation of the present utility model, and be not the restriction to model utility, the utility model limited range, see claim, within protection domain of the present utility model, can do any type of amendment.
