Description

  The present invention relates to a door weather strip mounting structure that is mounted corresponding to at least a wheel arch portion of a door panel of a rear door.

  In general, a door weather strip is attached to the peripheral portion of the vehicle door. In particular, in the rear door, there is a portion called a wheel arch corresponding to the rear wheel, and a weather strip is attached corresponding to the wheel arch portion (see, for example, Patent Document 1).

  When attaching a weather strip corresponding to a wheel arch part, first, a method of attaching a door panel via a double-sided adhesive tape is conceivable. However, in the case of attaching with a double-sided adhesive tape, the cost is increased, so the feasibility is poor.

Therefore, for example, as shown in FIG. 6, it is conceivable that the weather strip 82 is brought into contact with the door panel 81 and attached with a clip 83 at a predetermined interval in the longitudinal direction of the weather strip 82. It is done. According to this method, it is difficult to increase the cost as compared with the case of using a double-sided adhesive tape. That is, in consideration of cost, attachment using a clip is advantageous.
Japanese Patent Laid-Open No. 7-101244

  By the way, as shown to Fig.5 (a), the wheel arch part 84 mentioned above has comprised the curved shape. For this reason, as shown in FIG.5 (b), in the part corresponding to the wheel arch part 84 among the weather strips 82, it is necessary to make it curved and attach along the said arch shape. On the other hand, many portions of the weather strip 82 are formed by extrusion molding, and the portion corresponding to the wheel arch portion 84 is basically linear. When the weather strip 82 is to be attached in correspondence with the curved arch portion, the weather strip 82 is located at an intermediate portion of the adjacent clips 83 as shown by a two-dot chain line in FIG. May return to the original linear shape, and a so-called “short circuit” phenomenon may occur. In this case, in the intermediate portion, as shown in FIG. 7, the weather strip 82 is shifted to the outer edge side (lower side of the drawing) from the wheel arch portion, and the appearance quality is deteriorated due to the shift. There is a risk of causing problems such as a decrease in sealing performance.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a door weather strip that can suppress an increase in cost at the time of installation and can prevent problems caused by misalignment. It is to provide a mounting structure.

  Hereinafter, each means suitable for solving the above problem will be described in terms of items. In addition, the effect etc. peculiar to a corresponding means are added as needed.

Means 1. Of the door panel of the rear door, it is attached corresponding to at least the wheel arch portion, and has a mounting base and a hollow seal that bulges from the mounting base toward the inside of the vehicle and can contact the vehicle body opening edge when the rear door is closed. A door weatherstrip mounting structure comprising a portion,
A support means is fixed at least on the vehicle interior side of the door panel corresponding to the wheel arch portion, and a predetermined interval is provided along the wheel arch portion in a state where the attachment base is in contact with the support means. Attaching the door weather strip to the support means with a plurality of clips;
The outer edge portion of the support means is provided with a protrusion regulating means for restricting the protrusion to the outer edge portion side of the door weather strip ,
The support means includes a receiving plate portion with which the mounting base abuts, and the protrusion regulating means is a convex portion formed so as to be substantially orthogonal to the outer edge portion of the receiving plate portion,
The support means is fixed to the door panel, and a step is formed between a portion of the door panel where the support means is fixed and an outer edge of the door panel. And
The door weather strip mounting structure , wherein an outer edge portion of the receiving plate portion is provided with a leg portion extending in a direction opposite to the convex portion and contacting the outer edge portion of the door panel .

According to the means 1, the supporting means is fixed at least to the vehicle interior side of the door panel corresponding to the wheel arch portion, and the weather strip mounting base is brought into contact with the supporting means along the wheel arch portion. The door weather strip is attached to the support means with a plurality of clips at predetermined intervals. As described above, since the door weather strip is attached by the clip, it is possible to suppress an increase in the cost at the time of attachment as compared with the case of using the double-sided adhesive tape or the like. Further, a protrusion regulating means is provided on the outer edge portion of the support means. For this reason, the protrusion to the outer edge part side of the door weather strip is restricted between adjacent clips. Therefore, the weather strip does not shift to the outer edge side from the wheel arch portion, and problems such as a decrease in appearance quality and a decrease in sealability due to the shift can be prevented.
Further, according to the means 1, the protrusion is restricted by the convex portion formed so as to be substantially orthogonal to the outer edge portion of the receiving plate portion. Therefore, the above-described effects can be achieved without making the structure so complicated.
Further, conventionally, when there is no support means, it has been necessary to seal between the outer edge portion and the vehicle body opening edge of the inner surface of the door panel. In other words, the conventional weather strip needs to be thick enough to fill the gap between the two. On the other hand, in the means 1, the outer edge portion of the receiving plate portion is provided with a leg portion that comes into contact with the outer edge portion of the door panel. Therefore, as the door weather strip, the receiving plate portion and the vehicle body opening edge are provided. What is necessary is just to be able to seal the gap between them. Therefore, the volume (thickness) of the door weather strip can be reduced as compared with the conventional one.

  In addition, it is good also as "the said support means being used as an interior member (for example, resin garnish)." As described above, if the support means is used as an interior member, it is not necessary to provide a separate support means only for preventing the weather strip from being displaced, and the cost of the design can be improved while improving the design of the door as a whole. Increase suppression can also be aimed at.

Mean 2. 2. The door weather strip mounting structure according to claim 1, wherein an engaging portion of the clip is located in a space portion between the receiving plate portion and the door panel.

In the means 1 described above, the outer edge portion of the supporting means is supported by the leg portion, and a space is secured between the receiving plate portion and the door panel. And in the means 2, the latching | locking part of a clip is located in the said space part. For this reason, it is not necessary to form the hole for clip latching in a door panel, and the latching | locking part of a clip is not visually recognized from the exterior by presence of a leg part. Furthermore, since the clip can be positioned on the outer edge side of the door panel as much as possible, it is easy to prevent problems due to “turning” of the weather strip from the outer edge side.

Means 3. The door plate according to claim 1 or 2, wherein the receiving plate portion extends at an angle with respect to the extending direction of the door panel so that the outer edge portion is positioned closer to the vehicle inner side when the rear door is closed. The strip mounting structure.

  When the door weather strip is directly attached to the door panel, when the phenomenon of “short circuit” as described above occurs, the door weather strip slides along the door panel (extending direction) and from the wheel arch part. Will also shift to the outer peripheral side. On the other hand, in this means 3, the door weather strip is in contact with the receiving plate portion of the supporting means, and the extending direction of the door panel is such that the receiving plate portion is positioned on the inner side of the vehicle toward the outer edge side. It is inclined and extends. Accordingly, the shift stress is dispersed by the amount of the inclination, and coupled with the restriction by the convex portion, the shift to the outer peripheral side can be more reliably prevented. Further, in this case, since the shift can be prevented even if the protruding amount of the convex portion is not so large, it is possible to prevent the appearance quality from being lowered due to the increased protruding amount of the convex portion.

  In addition, when the rear door is closed, the seal part comes into contact with the opening edge of the vehicle body and is crushed and deformed, but as described above, the receiving plate part is inclined so that the outer edge side is located on the vehicle inner side. Therefore, when the seal portion is crushed, the seal portion hardly protrudes from the outer edge portion. For this reason, it is easy to prevent deterioration in appearance quality.

  Hereinafter, an embodiment will be described with reference to the drawings. As shown in FIG. 1, a front door 2 and a rear door 3 are provided in an automobile 1 so as to be openable and closable, and door weather strips are mounted so as to correspond to the peripheral portions of the doors 2 and 3. Yes. In particular, the rear door 3 has a portion called a wheel arch portion 4 corresponding to the rear wheel. As shown in FIG. 2, in this embodiment, a door weather strip (hereinafter simply referred to as a weather strip) 11 is attached so as to correspond to the wheel arch portion 4.

  In the present embodiment, the weather strip 11 is attached to the wheel arch portion 4 having a curved shape as described above with a clip 41 (see FIG. 3) at a predetermined interval in the longitudinal direction in a curved state. It has been. By adopting the structure attached with the clip 41 in this way, the increase in cost is suppressed as compared with the case where the double-sided adhesive tape is used.

  The weather strip 11 is made up of extruded portions 21 and 22 formed by extrusion molding, and a portion where the shape of the weather strip 11 needs to be greatly deformed is formed by molding. 23, 24 and 25 (parts with a hatched pattern in the figure). Moreover, the extrusion molding parts 21 and 22 of the weather strip 11 are substantially linear. In this embodiment, since the structure of the extrusion molding part 21 corresponding to the wheel arch part 4 and its attachment structure are characteristic, the structure in the said extrusion molding part 21 and its attachment structure are demonstrated in detail below.

  As shown in FIGS. 3 and 4, the weather strip 11 (extrusion molding portion 21) has an attachment base 12 and a hollow seal portion 13 that bulges from the attachment base 12 toward the vehicle body 5. Yes. In the present embodiment, both the mounting base 12 and the seal portion 13 are made of EPDM sponge rubber. Of course, the attachment base portion 12 may be formed of EPDM solid rubber, and the seal portion 13 may be formed of EPDM sponge rubber.

  In the present embodiment, the rear door 3 includes a door panel 30 including an inner panel 31 and an outer panel 32. At the outer edge of the door panel 30 (lower part of FIGS. 3 and 4), the inner panel 31 and the outer panel 32 are brought into contact with each other, and the outer panel 32 is bent inward to form a thin plate. On the other hand, in the inner peripheral side part (upper part of FIGS. 3 and 4) of the door panel 30, the inner panel 31 is bent in a substantially crank shape, thereby forming a stepped portion 33 between the outer edge portion. Has been. In the present embodiment, the arch garnish 51 constituting the support means is fixed to the inner panel 31 with screws or clips (not shown). The arch garnish 51 is provided corresponding to at least the wheel arch portion 4 as a part of the interior part, and is formed of a synthetic resin and has a plate shape. The arch garnish 51 includes a receiving plate portion 52 at a position corresponding to the outer edge portion of the door panel 30. Further, a convex portion 53 as an overhang restricting means is integrally formed so as to be substantially orthogonal to the outer edge portion of the receiving plate portion 52. Further, a leg portion 54 is formed integrally with the outer edge portion of the receiving plate portion 52 so as to extend in a direction opposite to the convex portion 53 and contact the outer edge portion of the door panel 30. At the same time, the receiving plate 52 extends obliquely with respect to the extending direction of the door panel 30 (vertical direction in FIGS. 3 and 4) so that the outer edge is closer to the vehicle inner side when the rear door 3 is closed. In addition, a clip hole 55 is formed in the receiving plate portion 52 at a predetermined interval in the longitudinal direction.

  Then, the engaging portion 42 of the clip 41 attached in advance to the attachment base 12 is fitted into the clip hole 55 in a state where the attachment base 12 of the weather strip 11 is brought into contact with the receiving plate portion 52. The weather strip 11 is attached to the arch garnish 51. In this case, the engaging portion 42 of the clip 41 is located in a space portion between the receiving plate portion 52 and the door panel 30 (a space portion sandwiched between the leg portion 54 and the step portion 33).

  Next, the effect of this embodiment comprised as mentioned above is demonstrated.

  As described above, since the configuration in which the weather strip 11 is attached by the clip 41 is employed, it is possible to suppress an increase in the cost at the time of attachment compared to the case of using a double-sided adhesive tape or the like.

  On the other hand, since the wheel arch portion 4 has a curved shape when viewed from the side of the vehicle, it is intended to attach the weather strip 11 (extrusion portion 21) having a straight shape with a clip 41 at a predetermined interval in the longitudinal direction. In such a case, there is a concern that the portion between the adjacent clips 41 is “short-circuited” and cannot follow the shape of the curved portion. In this regard, in the present embodiment, a convex portion 53 is provided on the outer edge portion of the receiving plate portion 52 of the arch garnish 51, and the protrusion of the weather strip 11 to the outer edge portion side is restricted by the convex portion 53. It will be. Therefore, the weather strip 11 does not shift to the outer peripheral side from the wheel arch portion 4, and problems such as a decrease in appearance quality and a decrease in sealing performance due to the shift can be prevented.

  Further, since the arch garnish 51 is used as an interior member, it is not necessary to provide a separate support means only for preventing the weather strip 11 from being displaced. Therefore, it is possible to suppress the increase in cost while improving the design of the rear door 3 as a whole.

  Furthermore, the weather strip 11 in this embodiment is in contact with the receiving plate portion 52 of the arch garnish 51 and extends in the direction in which the door panel 30 extends so that the receiving plate portion 52 is positioned closer to the outer edge side. It is inclined and extended. Therefore, the shift stress is dispersed by the amount of the inclination, and the shift to the outer peripheral side can be more reliably prevented in combination with the restriction by the convex portion 53. Further, since the shift can be prevented even if the protruding amount of the convex portion 53 is not so large, the protruding amount of the convex portion 53 can be made as small as possible.

  In addition, when the rear door 3 is closed, the seal portion 13 abuts against the opening edge of the vehicle main body 5 and is crushed and deformed to achieve a seal. Since it is inclined so as to be positioned, when the seal portion 13 is crushed, it is unlikely that the seal portion 13 protrudes extremely from the outer edge portion. For this reason, it is easy to prevent deterioration in appearance quality.

  Furthermore, in this embodiment, the leg part 54 is provided in the outer edge part of the receiving plate part 52, and the weather strip 11 should just seal the clearance gap between the receiving plate part 52 and the vehicle main body 5 opening edge. . Therefore, the volume (thickness) of the weather strip 11 can be made smaller than the conventional one.

  In addition, since the outer edge portion of the arch garnish 51 is supported by the leg portion 54, a space is secured between the receiving plate portion 52 and the door panel 30 (inner panel 31). And in this embodiment, the latching | locking part 42 of the clip 41 is located in the said space part. For this reason, it is not necessary to bother to form the hole for clip latching in the door panel 30. Further, due to the presence of the leg portion 54, the locking portion 42 of the clip 41 is not visually recognized from the outside. Furthermore, since the clip 41 can be positioned on the outer edge side (the lower side in the drawing) of the door panel 30 as much as possible, it is easy to prevent problems caused by “turning” of the weather strip from the outer edge side.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (A) Although the clip hole 55 is provided in the receiving plate portion 52 and the clip 41 is fitted in the left direction in FIGS. 3 and 4 in the above embodiment, the clip is directed from the bottom to the top in FIGS. It is good also as inserting.

  (B) The cross-sectional shape of the weather strip is not necessarily limited to that of the above embodiment. Therefore, for example, it can be embodied in a weather strip of a type having a separate lip, or can be embodied in a type of weather strip having a bridge portion for partitioning the hollow portion.

  Further, the weather strip may be embodied to be provided on the entire periphery of the rear door.

  (C) In the above embodiment, EPDM is exemplified as a material constituting the weather strip 11, but other rubber materials such as IR (isoprene rubber) and CR (chloroprene rubber) may be used. A resin material such as (olefin-based thermoplastic elastomer) may be used.
