Preferably, described air filter for automobile upper shell is by molding and forming, and the integral body structure that is square.
The utility model also provides a kind of air filter for automobile, comprise above-mentioned air filter for automobile upper shell, the air filter for automobile lower shell body being fixedly connected with described air filter for automobile upper shell, and the filter core being tightly connected with described air filter for automobile upper shell.
Air filter for automobile upper shell of the present utility model and air filter for automobile, adopt the noise reducing pipe of interpolation type, can not increase under the prerequisite of volume at air filter for automobile upper shell, reduce suction port noise, especially high frequency inflow noise is had to certain inhibitory action.
Accompanying drawing explanation
Fig. 1 is the stereogram of the air filter for automobile upper shell of the utility model mode of execution.
The top view of the air filter for automobile upper shell shown in Fig. 2 Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The air filter for automobile of the utility model mode of execution, comprise air filter for automobile upper shell 10 as depicted in figs. 1 and 2, the air filter for automobile lower shell body being fixedly connected with described air filter for automobile upper shell 10, and the filter core being tightly connected with described air filter for automobile upper shell.
Air filter for automobile lower shell body is provided with suction port, and suction port connects suction tude, with from outside air amount.Filter core filters the air sucking, and filters out the most small impurity particle.Air after filtering enters motor from air filter for automobile upper shell 10.Because filter core has certain thickness, the moulding of air filter for automobile lower shell body need to design by body outline, and air filter for automobile upper shell 10 surfaces need to be by hood inner panel and Sound-proof material profile design.
Refer to Fig. 1 and Fig. 2, the air filter for automobile upper shell 10 of the utility model mode of execution, the steam outlet pipe interface 13 that comprises main casing 11, the opening frame 12 of main casing 11 bottoms is set and is arranged at described main casing 11 sidepieces.Described opening frame 12 has the filter core being tightly connected with filter core and is connected plane 121.
In the present embodiment, the space of air filter for automobile upper shell 10 is narrower and small, only can guarantee the layout of steam outlet pipe interface 13 on its thickness.So, because engine compartment limited space, the volume of air-strainer is received restriction, by the control having influence on inflow noise.
For in the situation that air filter for automobile upper shell 10 volume spaces are restricted, effectively suppress inflow noise, described air filter for automobile upper shell 10 also comprises the noise reducing pipe 14 that is arranged at main casing 11 inside.Described noise reducing pipe 14 is fixedly connected with described main casing 11, and the outlet 141 of described noise reducing pipe 14 is connected with steam outlet pipe interface 13.The noise reducing pipe 14 that adopts interpolation type, can not increase under the prerequisite of volume at air filter for automobile upper shell 10, reduces suction port noise, especially high frequency inflow noise is had to certain inhibitory action.
