Abstract

The present invention discloses an air extractor of a motor vehicle.

The present invention is fixed to the rear panel of the vehicle, the frame of the rectangular frame shape; The hinge shaft is rotatably coupled to the frame to be rotated according to the pressure difference between the inside and outside of the vehicle to eliminate the pressure difference, and a rubber flip made of at least two divided bodies adjacent to each other. When the vortex or vibration occurs, the split body is partially absorbed by the vortex and the vibration because the flip consists of a plurality of divided bodies.

That is, the flip is operated stably to block the polluted air and noise from entering the room to keep the interior of the car comfortable.

At this time, the noise caused by the flap between the flap and the body panel, which is generated when one of the rear windows is opened, can also be reduced through the divided flip. The impact sound can also be greatly reduced.

Description

A air-extrator of car

The present invention relates to an automobile extractor, and more particularly, to an air extractor of an automobile capable of compensating a pressure difference between indoors and outdoors of an automobile, as well as suppressing noise generation due to vibration.

In general, an automobile is equipped with an air extractor (air extractor) to eliminate the pressure difference between the interior and exterior of the vehicle.

Referring to the general structure of such an air extractor, as shown in FIG. 1, a large frame of frame 10 and a rubber flap 20 which are hingedly coupled to the frame 10 in a rotatable manner are rotated. Although not shown, they are mounted and used invisibly from the outside between the side panel and the quarter panel mounted on the rear side of the vehicle.

The air extractor performs a function of controlling pressure while simultaneously flipping the flip 20 selectively by the pressure difference between the interior and the exterior of the vehicle, and blocking the dust flowing in from the outside.

That is, the flip 20 is opened when there is a fluid flow in the room, on the contrary is hinged on the frame 10 in a configuration that is closed when introduced from the outdoors.

However, in such an air extractor of a typical vehicle, the flip 20 does not operate smoothly when irregular vortices or vibrations are generated in the rear portion of the vehicle generated when the vehicle is driven, thereby making noise from the outside of the vehicle to the interior. In addition, soil or dust is often introduced to worsen the indoor environment.

In addition, when driving in a state in which any one of the rear window is opened when driving the car causes a very serious vibration noise occurs.

The reason for this problem is that the wind is periodically introduced and discharged into the room when one of the rear windows is open, and accordingly, the flip of the air extractor is repeatedly opened and closed, and thus the surrounding body panels. It is caused by having

In addition, when the vehicle travels at a speed of about 40 km / h, a hitting sound is generated from the surface of the vehicle, which increases the amount of air flowing into the trunk and, accordingly, the amount of air passing through the air extractor also increases. This is because the speed of the stand increases.

An object of the present invention for solving the above problems is that the flip is operated stably even when the unstable vortex or vibration generated from the rear of the car can completely block the inflow of noise and outdoor air, as well as the rear The present invention provides an air extractor for a vehicle that can reduce vibration noise caused by excitation caused by the flap of the air extractor generated when driving one of the windows in an open state.

Air extractor of the vehicle according to the present invention for achieving the object is fixed on the rear panel of the vehicle, the frame of the rectangular frame; The hinge shaft is rotatably coupled to the frame to be rotated according to the pressure difference between the inside and outside of the vehicle to eliminate the pressure difference, and a rubber flip composed of at least two divided bodies adjacent to each other. do.

As expected effects due to the above-described features of the present invention, since the flip is composed of a plurality of divided bodies during vortex or vibration generation, the divided body partially absorbs the absorption of the vortex and the absorption of the vibration.

The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

2 is an exemplary view showing an air extractor of a vehicle according to the present invention.

As shown therein, the air extractor of the vehicle according to the present invention includes a frame 100 having a rectangular frame shape positioned between the rear panel of the vehicle, that is, the quarter panel and the side outer panel.

The rubber flip 200 is pivotally hingedly coupled to the frame 100. In particular, the rubber flip 200 is not composed of a single body, but two or more divided bodies 210 adjacent to each other. )

That is, the divided bodies 210 are installed adjacent to each other to form one rubber flip 200.

By configuring the rubber flip 200 as the divided body 210 as described above, the body 210 of the rubber flip 200 on the part side that is generated even when the vortex or vibration generated during driving of the vehicle is generated is operated stably. Not only does it block the inflow of outdoor air into the room, but also absorbs vibrations by the buffering effect of each other, thereby maintaining a comfortable indoor environment.

In this case, the noise caused by the collision between the rubber flip 200 and the body panel, which is generated when the vehicle is driven with any one of the rear windows open, is greatly reduced, and it is possible to maintain a comfortable indoor environment. The noise generated when the flow of air generated at a driving speed of about 40 km / h with one open is greatly reduced.

In addition, the body 210 of the rubber flip 200 is partially operated even though a minute air flow is generated in the room through minute gaps between the bodies 210, thereby maintaining a comfortable indoor environment. do.

In addition, since the gap between the bodies 210 is very fine, it will be noted that the inflow of foreign matter or moisture can be completely blocked.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with it will know easily.
