Japanese Patent Application Publication No. 2018-176962

In a vehicle door in which a belt molding is attached to a door outer panel along a belt line, attachment holes for fixing the belt molding are present at the front and rear ends of the door outer panel. These mounting holes are hidden behind the belt molding and become invisible by attaching the belt molding to the door outer panel. However, these mounting holes are holes that connect the inside and outside of the vehicle door, and are wider than the area through which the clip that fixes the belt molding to the door outer panel passes through, so wind noise from outside the vehicle can be heard while the vehicle is running. This causes the particles to enter the door through the holes and penetrate into the vehicle interior.

In order to suppress the intrusion of such wind noise into the door, the front side of the conventional front door utilizes a weather strip in close proximity to close the gap between the mounting holes as much as possible. It is difficult to completely close the gap between the mounting holes. Further, due to design or structural issues, it may not be possible to use weather strips to close gaps between mounting holes. Further, in the rear side of the front door of the prior art, there is no structural space to insert the molded part of the weather strip, so it is not possible to use the weather strip to close the gap between the mounting holes. Therefore, it is difficult to completely close the gap between the mounting holes in the door outer panel using weather strips alone, and conventional vehicle doors have had the problem of suppressing wind noise from entering the door. .

Therefore, an object of the present invention is to close the gap between the mounting hole formed in the door outer panel for attaching the belt molding, and to suppress wind noise from entering the door through the mounting hole and transmitting into the vehicle interior. shall be.

A vehicle door according to the present invention includes a belt molding that is attached to a door outer panel along a belt line, and a mounting hole for attaching the belt molding is formed in the door outer panel, and the vehicle door has a door frame. A door frame attachment part having an extension part extending into the attachment hole is attached to the door frame attachment part, and a soft member is attached to the extension part of the door frame attachment part so as to close a gap between the attachment hole. It is characterized by

The present invention can close the gap between the mounting hole formed in the door outer panel for attaching the belt molding, thereby suppressing wind noise from entering the door through the mounting hole and transmitting into the vehicle interior.

The cap 5 has a clip function for attaching the frame molding 4b to the vehicle door 10 and a function to cover the terminal edge of the frame molding 4b. The cap 5 is disposed close to the attachment hole 11 and includes an extension 5a extending into the attachment hole 11.

A sponge member 6 is attached to the extension portion 5a of the cap 5 as a soft member so as to close the gap of the attachment hole 11. The sponge member 6 is formed with an insertion hole 6a into which the extension 5a of the cap 5 is inserted. The sponge member 6 is attached to the cap 5 by inserting the extension portion 5a of the cap 5 into the insertion hole 6a of the sponge member 6 and fixing it by a method such as adhesion. When the sponge member 6 is assembled to the vehicle door 10, it comes into contact with the door outer panel 1 and the door inner panel 2. As the material of the sponge member 6, for example, ethylene propylene diene rubber foam can be used. In addition, instead of the sponge member 6, for example, EPDM (Ethylene Propylene Diene Methylene Linkage), TPV (Thermoplastic Vulcanizates), or TPO (Thermoplastic Olefinic Ela) can be used. It is possible to use a soft member made of a material called "Stomer".

Then, after attaching the cap 5 to the lower end of the front end of the frame molding 4b and attaching the sponge member 6 to the extension part 5a of the cap 5, the belt molding 3 is attached to the door outer panel 1 as shown in FIG. It will be done. When the belt molding 3 is attached to the door outer panel 1, the small lip 3a attached to the inner end of the belt molding 3 in the vehicle width direction contacts the cap 5, and the lower side of the outer end of the belt molding 3 in the vehicle width direction contacts the cap 5. A body touch lip 3b attached to the door contacts the door outer panel 1. By attaching the belt molding 3 to the door outer panel 1 in this manner, the sponge member 6 is hidden behind the belt molding 3 and becomes invisible.

In the vehicle door 10, by attaching the sponge member 6 to the extension part 5a of the cap 5 as described above, the gap between the attachment hole 11 of the door outer panel 1 can be closed, so that wind noise is absorbed from the attachment hole while the vehicle is running. 11 into the vehicle door 10 and permeate into the vehicle interior.

Next, the structure of the rear end of the belt line of the vehicle door 10 will be explained using FIGS. 3 and 4. FIG. 3 is a perspective view showing the rear end of the belt line of the vehicle door 10 as viewed from the outside of the vehicle, and shows the state before the belt molding 3 is attached. FIG. 4 is a cross-sectional view taken along the line BB in FIG. 3, showing a state in which the belt molding 3 is attached.

As shown in FIGS. 3 and 4, the door outer panel 1 of the vehicle door 10 has a substantially horizontal upper surface 1a, and a mounting hole 12 for mounting the belt molding 3 is formed at the rear end of the upper surface 1a. There is. The attachment hole 12 is formed by cutting out the inside of the rear end portion of the upper surface 1a of the door outer panel 1 in the vehicle width direction. The attachment hole 12 has an elongated shape extending in the front-rear direction, and a front portion 12a, which is the front portion of the attachment hole 12, is used for attaching the belt molding 3 to the door outer panel 1. The belt molding 3 is attached to the door outer panel 1 along the belt line by inserting clips into the rear part 11a of the attachment hole 11 and the front part 12a of the attachment hole 12.

A rear end portion of the door frame 4 extends in the vertical direction along the B pillar. A frame garnish 7 is attached as an accessory to the door frame on the outer side in the vehicle width direction of the rear end portion of the door frame 4 that extends in the vertical direction. The frame garnish 7 is a resin component attached to improve the design of the exterior of the vehicle door 10. The frame garnish 7 is attached to the rear end of the door frame 4 with double-sided tape. The frame garnish 7 includes an extension 7a extending into the attachment hole 12 at its lower end. The extension portion 7a extends from the lower end of the frame garnish 7 toward the outside in the vehicle width direction into the attachment hole 12.

A sponge member 8 is attached to the extension portion 7a of the frame garnish 7 as a soft member so as to close the gap between the attachment holes 12. The sponge member 8 is formed with an insertion hole 8a into which the extension 7a of the frame garnish 7 is inserted. The sponge member 8 is attached to the frame garnish 7 by inserting the extension portion 7a of the frame garnish 7 into the insertion hole 8a of the sponge member 8 and fixing it by a method such as adhesive. As the material of the sponge member 8, for example, ethylene propylene diene rubber foam can be used. Moreover, instead of the sponge member 8, for example, EPDM (Ethylene Propylene Diene Methylene Linkage), TPV (Thermoplastic Vulcanizates), or TPO (Thermoplastic Olefinic Ela) can be used. It is possible to use a soft member made of a material called "Stomer".

After the sponge member 8 is attached to the extension portion 7a of the frame garnish 7 in this manner, the belt molding 3 is attached to the door outer panel 1 as shown in FIG. When attaching the belt molding 3 to the door outer panel 1, the folded portion 3c that is folded back downward from the inner end in the vehicle width direction of the belt molding 3 bites into the sponge member 8 so as to deform the upper surface of the sponge member 8. , improved sealing performance. When the belt molding 3 is attached to the door outer panel 1, the small lip 3a attached to the folded portion 3c of the belt molding 3 comes into contact with the frame garnish 7, and is attached to the lower side of the outer end of the belt molding 3 in the vehicle width direction. The body touch lip 3b contacts the door outer panel 1. As the small lip 3a contacts the frame garnish 7 and the body touch lip 3b contacts the door outer panel 1 in this manner, the sponge member 8 is hidden behind the small lip 3a and the body touch lip 3b and becomes invisible.

In the vehicle door 10, by attaching the sponge member 8 to the extension part 7a of the frame garnish 7 as described above, the gap between the attachment hole 12 of the door outer panel 1 can be closed, thereby reducing wind noise while the vehicle is running. It can be suppressed from entering the inside of the vehicle door 10 through the hole 12 and permeating into the vehicle interior.

In addition, by attaching the sponge member 8 to the frame garnish 7 so as to close the gap between the attachment holes 12 as described above, the adhesive function of the double-sided tape for attaching the frame garnish 7 to the door frame 4 in the vehicle door 10 is reduced. Even in this case, the effect of inhibiting the movement of the frame garnish 7 from falling off from the door frame 4 can be exhibited.
