Description

Wind noise blocking room structure of door

(Technology field)

The present invention relates to a wind noise blocking room structure of a door, and more particularly, to a wind noise blocking room structure of a door that blocks wind noise entering into a gap between a front door and a rear door of a passenger vehicle having a front door and a rear door. It is about.

(Prior art)

Since the vehicle is a transport mechanism that runs at high speed while cutting air by the power of the engine, various noises are generated during driving such as noise caused by the engine operation and wind noise caused by the collision of the vehicle and air. It is always in contact with various foreign objects such as dust, soil and water. Therefore, for a good ride comfort, it is desirable that the occupant of the vehicle is not as influenced by such noise and foreign matter as possible.

Since the door is formed of a panel separate from the body of the vehicle and configured to be opened and closed with respect to the vehicle body, a gap is formed between the panel constituting the door and the vehicle body in which the door is installed, and the gap is caused by the noise and foreign matter. It is the main passage that enters the interior of the vehicle.

Therefore, the vehicle body in which the door is installed is equipped with a weather strip or seal structure along the body surface where the entire circumference of the door abuts in order to prevent these noises and foreign substances from entering the room.

1 is a cross-sectional view of a cent pillar where a front door and a rear door of a passenger vehicle having four doors meet. As shown, the center pillar 1 has a rear door 3 composed of an inner rear door panel 31 and an outer rear door panel 33 so as to be opened and closed by a hinge 5, and the rear door 3 In front of the) is a front door 7 composed of an inner front door panel 71 and an outer front door panel 73.

At the end of the rear door 3, a hemming flange 35 is formed in which the end of the outer rear door panel 33 is folded inward to surround the end of the inner rear door panel 31. Similarly, the front door is formed. At the end of (7), a hemming flange 75 is formed in which the end of the outer front door panel 73 is folded inward to surround the inner front door panel 71. The hemming flanges 35 and 75 soften the finishing of the doors 3 and 7 and prevent the ends of the doors from interlocking when the doors are opened and closed.

When the rear door 3 and the front door 7 are closed, a gap 9 is formed between the two doors 3 and 7, and this gap 9 is covered by the center pillar 1. Even if the gap 9 is closed by the center pillar 1, the rear door 3, and the front door 7, the wind noise generated when the vehicle runs while hitting the air is driven through the gap 9. It cannot be completely blocked from entering the room.

Accordingly, an object of the present invention is to prevent a wind noise from being introduced into a gap between a rear door panel and a front door so as to obtain a more comfortable ride.

The object of the present invention described above is achieved by a wind sound blocking room structure of a door in which a wind sound blocking room made of an elastic material is bonded to a gap formed between the rear door and the front door.

Specifically, the object of the present invention, in the wind noise blocking room structure of the door that is installed in the gap between the rear door and the front door of the vehicle, the end of the outer door panel of the rear door is folded inward end of the inner door panel The wind blowing sound blocking structure of the door, characterized in that the wind blowing sound blocking seal of the elastic material is bonded to the hemming flange wrapping the inner front door panel of the outer door panel of the front door. Is achieved by.

The wind noise blocking chamber of the elastic material is preferably bonded to the hemming flange of the rear door with a double-sided adhesive tape elastic rubber having a hollow portion in the center.

Hereinafter, with reference to the accompanying drawings will be described in detail the structure of the wind noise blocking room of the door according to the present invention. The following embodiments are merely illustrative of the structure of the wind noise blocking room of the door according to the present invention, and are not intended to limit the scope of the present invention.

Figure 2 is a cross-sectional view of the cent filler that the front door and the rear door is installed with the wind sound blocking room structure of the door according to the present invention. As shown, the wind-wind sound blocking room structure of the door according to the present invention, the wind-wind sound blocking of the elastic material in the gap (9) formed in the portion where the front door 7 and the rear door 3 described with reference to FIG. It is made by attaching the seal 11.

That is, the end of the outer rear door panel 33 of the rear door 3 is folded inward to cover the end of the inner rear door panel 31 and the outer front door panel 73 of the front door 7 and the hemming flange 35. Hemming of the rear door 3 to prevent the wind noise from entering the room by blocking the gap 9 inevitably formed between the hemming flange 75 surrounding the inner front door panel 71 by folding the end of For example, the wind blowing sound blocking chamber 11 made of elastic rubber having a hollow 13 formed at the center thereof is attached to the flange 35 with a double-sided adhesive tape 15.

According to the wind noise blocking room structure of the door as described above, the wind noise blocking room 11 blocks the wind blowing sound generated outdoors when the vehicle is driven. That is, in the state where the rear door 3 and the front door 7 are closed, the hemming flange 75 of the front door 7 presses the wind noise blocking chamber 11, thus completely closing the gap 9. By closing, it completely blocks the inflow of wind sound.

According to the wind noise blocking room structure of the door according to the present invention described above, between the hemming flange 35 of the rear door panel 33 and the hemming flange 75 of the front door 7, the wind noise blocking room of the elastic material ( According to the structure that 11) is bonded, the wind noise is prevented from entering the gap between the rear door panel and the front door, thereby providing a more comfortable ride.
