FIG. 3 is an enlarged cross-sectional view taken along arrow 3-3 in FIG. 1 showing a vehicle door structure provided on the rear door.

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. In the drawing, the arrow FR indicates the front of the vehicle, the arrow UP indicates the upper side of the vehicle, and the arrow IN indicates the inner side of the vehicle.

  In FIG. 1, a vehicle door structure S according to the present embodiment relates to a sound insulation structure of a belt line L of a front door 10 which is an example of a vehicle door. As shown in FIG. 2, the vehicle door structure S includes a door outer panel 11, an outer weather strip 12, a door frame 13, an outer garnish 14, and a sound insulation member 15.

  In FIG. 2, the door outer panel 11 is a member disposed on the vehicle outer side of the front door 10. The front door 10 includes a door outer panel 11 and a door inner panel (not shown). The door inner panel is disposed on the vehicle inner side of the door outer panel 11. An outer weather strip 12 and a sound insulation member 15 are attached to the upper end of the door outer panel 11.

  The outer weather strip 12 is a seal member provided along the upper end of the door outer panel 11 and is made of an elastic body such as rubber or elastomer. The outer weather strip 12 is fitted to the upper end of the door outer panel 11 mainly in a range along the side glass 16 in FIG. Further, the end portion of the outer weather strip 12 on the vehicle rear side overlaps the outer garnish 14 in the vehicle width direction, and is in contact with the outer garnish 14 and the door outer panel 11 (FIG. 2).

  In FIG. 2, the door frame 13 extends from the end of the front door 10 in the front-rear direction of the vehicle, for example, from the end on the vehicle rear side, and constitutes a part of a frame-shaped door sash. The door frame 13 is disposed at a position overlapping the vehicle center pillar (not shown) in the vehicle width direction when the front door 10 is closed. The door frame 13 is provided with a glass run (not shown) for the side glass 16. The glass run is a guide portion that guides the raising and lowering of the side glass 16. The door frame 13 is formed with an attachment hole 13A that fits with a clip 14A of an outer garnish 14 described later.

  The outer garnish 14 is a resin decorative member that is provided outside the door frame 13 and covers the door frame 13. Similar to the door frame 13, the outer garnish 14 is provided at a position overlapping the center pillar in the vehicle width direction when the front door 10 is closed. A clip 14 </ b> A that protrudes toward the inside of the vehicle is integrally provided at the lower end of the outer garnish 14. When attaching the outer garnish 14 to the door frame 13, the clip 14 </ b> A is inserted into the attachment hole 13 </ b> A of the door frame 13. A slight gap 17 is formed between the outer garnish 14 attached to the door frame 13 and the door frame 13.

  The sound insulation member 15 is made of, for example, a polyolefin-type elastomer, and a fitting portion 15A, a seal portion 15B, and a mounting portion 15C are integrally formed. The fitting portion 15 </ b> A is a portion that fits into a flange 11 </ b> A provided at the upper end of the door outer panel 11.

  The seal portion 15 </ b> B is a portion that is disposed at least in the gap 17 between the outer garnish 14 and the door frame 13, and is formed so as to narrow the gap 17. Specifically, the sound insulation member 15 has a thin wall portion 15 </ b> D that extends in the vehicle vertical direction along the back surface of the outer garnish 14. The seal portion 15B is provided at the upper end of the thin portion 15D, and is formed in a wall shape that extends from the outer garnish 14 side to the door frame 13 side and terminates. In the sound insulating member 15, the fitting portion 15 </ b> A and the thin portion 15 </ b> D are coupled by, for example, a seal portion 15 </ b> E having a U-shaped cross section. The seal portion 15E narrows the gap 18 between the door outer panel 11 and the door frame 13, and closes the gap 19 between the door outer panel 11 and the outer garnish 14.

  The attachment portion 15C is a portion that is locked to the outer garnish 14 when the outer garnish 14 is attached to the door frame 13, and is, for example, a through hole formed in the thin portion 15D. A clip 14A of the outer garnish 14 is inserted through the attachment portion 15C, and the attachment portion 15C is locked to the clip 14A.

  The vehicle door structure S can be applied not only to the front door 10 but also to the rear door 20 as shown in FIG. The configuration of each part in FIG. 3 is the same as the configuration of the front door 10, and thus the same reference numerals are given to the same parts, and description thereof is omitted.

  In the rear door 20, the gap 17 between the outer garnish 14 and the door frame 13 is narrower than the gap 17 (FIG. 2) of the front door 10. On the other hand, the gap 18 between the door outer panel 11 and the door frame 13 is wider than the gap 18 (FIG. 2) of the front door 10. The shape of the sound insulation member 15 is changed in accordance with the difference between the gaps 17 and 18. Specifically, since the gap 17 is relatively narrow at the cross-sectional position shown in FIG. 3 of the rear door 20, the wall-shaped seal portion 15B in FIG. 2 is not provided. In the rear door 20, since the gap 18 is relatively large, the seal portion 15E is large in the vehicle width direction (door thickness direction).

  In the front door 10 and the rear door 20, the gaps 17 and 18 are appropriately changed depending on the position in the vehicle front-rear direction. Moreover, in order to improve sound insulation, the sound insulation member 15 may further be provided with a seal portion corresponding to the gap between the respective portions.

(Function)
This embodiment is configured as described above, and the operation thereof will be described below. In FIG. 2, in the vehicle door structure S according to the present embodiment, sound outside the vehicle enters the front door 10 from the gap 17 between the outer garnish 14 and the door frame 13 by the seal portion 15 </ b> B of the sound insulating member 15. Can be suppressed. Specifically, the sound that enters the front door 10 in the direction of arrow A through the gap 17 can be reduced by the seal portion 15B. Even if the sound passes between the seal portion 15B and the door frame 13, since the gap 17 is narrowed by the thin portion 15D, the intrusion of the sound is reduced. Furthermore, since the gap 18 between the door outer panel 11 and the door frame 13 is narrowed by the seal portion 15E, the intrusion of sound into the front door 10 can be suppressed. Further, since the seal portion 15E closes the gap 19 between the door outer panel 11 and the outer garnish 14, the intrusion of sound through the gap 19 is also suppressed. The reduction of the intrusion sound by the thin wall portion 15D and the seal portion 15E is the same in the rear door 20 shown in FIG.

  When the sound insulation member 15 is assembled to the front door 10, the sound insulation member 15 is temporarily placed on the door outer panel 11 and the door frame 13 by fitting the fitting portion 15 </ b> A to the flange of the door outer panel 11. Can do. When the outer garnish 14 is attached to the door frame 13, the clip 14 </ b> A is inserted into the attachment portion 15 </ b> C of the sound insulation member 15, and the clip 14 </ b> A is inserted into the attachment hole 13 </ b> A of the door frame 13. Thereby, the attachment portion 15 </ b> C of the sound insulating member 15 is locked to the outer garnish 14. In other words, the sound insulation member 15 is attached to the door frame 13 together with the outer garnish 14. The assembly of the sound insulation member 15 is the same in the rear door 20 shown in FIG.

  Therefore, as compared with the case where a caulking sponge (not shown) is used as the sound insulating member, the work of assembling the sound insulating member 15 is easier and the mounting position of the sound insulating member 15 is less likely to vary. Therefore, it is difficult for the sound insulation property to decrease due to this variation. For this reason, the sound insulation member 15 can be easily assembled on the vehicle exterior side of the front door 10, and a decrease in sound insulation property due to variations in the mounting position of the sound insulation member 15 can be suppressed.
