Specific embodiment

Further to illustrate that this utility model is to reach technological means and effect that predetermined utility model purpose is taken, Below in conjunction with accompanying drawing and preferred embodiment, describe in detail as follows.

This utility model provides a kind of acoustic filter, and the acoustic filter can make the air-flow for flowing through acoustic filter become smooth-going, have Effect ground reduces air resistance coefficient.The front view of the acoustic filter that Fig. 1 is provided for this utility model embodiment, Fig. 2 are acoustic filter in Fig. 1 Top view, side views of the Fig. 3 for acoustic filter in Fig. 1, Fig. 4 flow through the acoustic filter seasonal epidemic pathogens that this utility model embodiment is provided for air-flow The schematic diagram of rheology, as shown in Figures 1 to 4, the acoustic filter that this utility model embodiment is provided is installed on the chassis of automobile, Including housing and multiple noise elimination cavities, the setting of its noise elimination cavity is referred to prior art, will not be described here, the housing of acoustic filter Including barrel 10 and the top cover 20 positioned at 10 two ends of barrel, the side on barrel 10 away from automobile chassis, i.e., towards ground Side is formed with multiple guiding gutters 30 extended along motor vehicle length direction, as shown in figure 4, when disorderly air-flow is entered below automobile And when acoustic filter, disorderly air-flow (air-flow is indicated by an arrow) can be become smooth-going by the guiding gutter 30 on acoustic filter, subtract Few air-flow and the friction of suppressor case, reduce air resistance coefficient.

Specifically, the surface of barrel 10 protrudes above and is formed with multiple convex tendons 11, and in the present embodiment, convex tendon 11 is only formed at On surface of the barrel 10 away from automobile chassis side, convex tendon 11 runs through acoustic filter barrel 10 along the long axis direction perpendicular to acoustic filter Away from the surface of automobile chassis side, above-mentioned guiding gutter 30 is located between two adjacent convex tendons 11.It is to be appreciated that convex tendon 11 setting can also increase the intensity of acoustic filter barrel 10.

Further, as shown in figure 3, barrel 10 include upper surface 12 towards automobile chassis direction, away from chassis direction Lower surface 13, the first side 14 being connected between upper surface 12 and lower surface 13 and second side 15,14 court of first side To the front end of automobile, rear end of the second side 15 towards automobile, above-mentioned guiding gutter 30 are formed on the lower surface 13 of barrel 10, From in terms of the end face direction of acoustic filter, the end face of barrel 10 is similar to ellipse, i.e., in the width of acoustic filter, upper surface 12 Distance of the distance at the middle part away from lower surface 13 in portion more than the end to 13 respective end of lower surface of upper surface 12, first side 14 and second side 15 be arc, when being installed on automobile chassis, positioned at the arc of the first side 14 of front portion of car body Radius of the radius of shape less than the arc of the second side 15 positioned at rear portion of car body.Due to the half of the arc of first side 14 Radius of the footpath more than the arc of second side 15, therefore, it is possible to further reduce the air resistance coefficient of acoustic filter.

In sum, this utility model is by making to arrange along motor vehicle length on lower surface 13 of the acoustic filter away from automobile chassis The guiding gutter 30 that direction extends so that disorderly air-flow becomes smooth-going below the acoustic filter, is effectively reduced then automobile Air resistance coefficient.

This utility model additionally provides a kind of automobile, including above-mentioned acoustic filter, with regard to the other technical characteristics of the automobile, Prior art is referred to, be will not be described here.
