Description

[Detailed Description of the Invention] This invention relates to a vehicle interior air exhaust device that discharges air from the interior of a vehicle through an exhaust port provided in the vehicle body.

Conventionally, an air exhaust port that communicates with the interior of the vehicle is opened at the rear of the exterior side of the vehicle, for example near the rear end of the rear side window, to prevent positive pressure from the outside air intake or generated on the exterior side of the vehicle while the vehicle is running. The air inside the vehicle is exhausted by negative pressure.

However, since the conventional air exhaust vents mentioned above are provided on the outer side of the car body, the number of parts increases, such as the need to meet the design requirements of the car and attach decorative parts such as grilles to prevent rainwater from entering the car interior. In addition, it also has disadvantages such as an increase in the number of man-hours required for installation.

BACKGROUND ART In recent years, side protectors that are attached to both sides of the outer panel of a vehicle body have become wider in order to prevent damage to the outer panel of the vehicle body or to increase the design effect.

In order to eliminate the above-mentioned problems by focusing on such side protectors, this invention has a substantially flat side protector that extends almost linearly in the front-rear direction over the entire length of the vehicle body, and a plurality of side protectors that are slanted downward on the outside of the vehicle. A slit is bored in the exhaust port, and an opening that communicates with the interior of the vehicle is formed in the outer panel of the vehicle body corresponding to the slit to serve as an exhaust port, thereby reducing the number of parts and the number of installation steps.

Hereinafter, embodiments of this invention will be described in detail based on the drawings.

Referring to FIG. 1, 1 is a vehicle body, and 2 is a side protector attached to the outermost side surface 1a of the vehicle body 1 to prevent damage to the outer panel of the vehicle body.

The substantially flat side protector 2 is made of rubber or synthetic resin, and is affixed, for example, in a straight line in the front-rear direction of the vehicle over the entire length of the vehicle body, with adhesive 3, and attached to the rear fender of the side surface portion 1a of the vehicle body. As shown in FIG. 2, the attachment part 2a to the part 1b has a slit 4 in the front and rear direction.
A plurality of slits 4 are formed, and the slits 4 are inclined downwardly toward the outside of the vehicle body.

Further, a slit 4 bored in the side protector 2
An opening 5 is formed in the side protector 1b corresponding to the side protector 2, and the lowermost end of the opening 5 is located above the lowermost slit 4a formed in the side protector 2. On the flange 5a formed with the opening 5,
A duct 6 made of rubber, synthetic resin, etc.
It is attached by a fitting part 6a provided at one end of the.

Note that the duct 6 may be formed of a steel plate or the like, and one end of the duct 6 may be welded and fixed to the seven flange 5a.

7 is the side part of the rear bumper.

In the present invention configured as described above, when the vehicle is running, the airflow flowing along the tail side surface portion 1a of the vehicle body and the side protector 2 extending along the substantially entire length of the vehicle body creates a negative pressure in the vehicle interior 8. Air introduced from the front outside air introduction hole (not shown) circulates within the vehicle interior 8 and is discharged to the exterior of the vehicle interior through the opening 5 and the slit 4.

Further, since the opening 5 is provided with a duct 6 extending above the opening 5, rainwater and the like can be prevented from entering.

Further, even if rainwater or the like infiltrates, the duct 6 extends above the opening 5, so that it will not enter the vehicle interior 81.

Although the slit 4 is formed to be elongated in the front-rear direction as shown in the drawings, it may have another shape.

Although the bent slit 4 and the opening 5 corresponding to the slit 4 are formed in the rear fender, they can also be formed in the front door or rear door on both sides of the vehicle.

As explained above, the present invention involves making slits in the side protector made of rubber or synthetic resin that is attached to the outermost side of the vehicle body, and openings that communicate with the interior of the vehicle in the vehicle body outer plate corresponding to the slits. The side protector is located at a position that protrudes from the outermost side of the vehicle body, so the negative pressure generated is greater than that of conventional air exhaust ports provided on the outer panel of the vehicle body. The exhaust power of indoor air becomes stronger.

The grille, etc. that is conventionally attached to the exhaust port can also be used as a side protector to prevent damage to the outer skin of the vehicle on the side of the vehicle. The number of points can be reduced and the number of installation steps can also be reduced.

Furthermore, this invention has a simple structure and is easy to manufacture.

Furthermore, since the slit of the present invention is inclined downwardly toward the outside of the vehicle, it has the effect of preventing rainwater from penetrating.
