Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a body side weather strip mounting structure in which a weather strip is mounted along a body flange of an automobile body panel.
[0002]
[Prior art]
This will be described with reference to FIGS. A body side weather which is attached to a body flange 4 formed by superposing the inner panel 2 and the outer panel 3 along the door opening of the automobile body panel 1 and ensures a sealing property between the door sash 5 and the like. The strip 20 generally includes an attachment base portion 21 and a hollow seal portion 22 having a substantially U-shaped cross section. In addition, a cored bar 23 is embedded in the mounting base 21 in order to ensure a sufficient clamping force with respect to the body flange 4. The body flange 4 is also set to a sufficiently large length in order to secure a sufficient assembling force with the mounting base 21. In FIG. 2, reference numeral 8 denotes a door weather strip, reference numeral 9 denotes a glass run, and reference numeral 9a denotes a door glass.
[0003]
In this conventional technique, there is a problem that the weight of the weather strip 20 and the body panel 1 is increased and the manufacturing cost is increased because the core metal is embedded and the length of the body flange 4 is set large. Further, since the cored bar 23 is embedded, there is a problem that when the weather strip 20 is attached to the body flange 4, expansion and contraction are likely to occur and positioning is difficult.
[0004]
Unlike such a structure, there is an attachment structure in which the weather strip is fixed to the outer panel of the body panel with a clip (see, for example, Patent Document 1).
[0005]
[Patent Document 1]
Utility Model Registration No. 255529 (FIG. 3)
[0006]
This mounting structure has an advantage that positioning is easy because the weather strip is fixed by a clip.
[0007]
[Problems to be solved by the invention]
However, since the weather strip described in Patent Document 1 is fixed to the outer panel of the body panel, it is still necessary to set the length of the body flange large, and there is a problem that the weight of the body panel increases. In other words, it is necessary to secure a space for positioning the head of the clip in addition to the space for positioning the hollow seal portion directly under the outer panel near the body flange. Arise.
[0008]
Further, if the space where the head of the clip is located is set small in order to avoid such a problem, it becomes difficult to insert the clip and it becomes difficult to attach the weather strip. As a result, the weather strip mounting posture tends to be unstable, which also affects the door closing performance.
[0009]
Further, since the weather strip is fixed to the outer panel, the mounting hole formed in the outer panel is exposed outside the vehicle. Therefore, there is a problem that rain water or car wash water adheres to the mounting hole and rust is easily generated.
[0010]
The present invention was devised in view of these problems, and provides a body side weather strip mounting structure that can be reduced in weight, can be easily positioned and mounted, and does not cause rust on the body panel. This is the issue.
[0011]
[Means for Solving the Problems]
This will be described with reference to FIGS. 1, 3 and 4. The body side weather strip mounting structure according to the present invention includes a body having a mounting base 11 and a hollow seal portion 17 along a body flange 4 formed by superposing an inner panel 2 and an outer panel 3 of an automobile body panel 1. In the mounting structure in which the side weather strip 10 is mounted, the mounting base 11 is connected to the vehicle interior portion 16a of the sandwiching section 16 having a substantially U-shaped cross section that sandwiches the body flange 4, and the upper wall 13 with the clip insertion hole 13a. the substantially U-shaped cross section base body 12 made of the side wall 1 5 and the lower wall 1 4 formed by integrally molded, bored a clip attachment hole 2a before Symbol inner panel 2, the insertion hole 13a and the mounting The clip 7 is inserted through the hole 2a, and the mounting base 11 is fixed in the vicinity of the body flange 4 of the inner panel 2.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
1 and 3 show a first embodiment of a body side weather strip mounting structure according to the present invention. This is because the inner panel 2 and the outer panel 3 of the automobile body panel 1 are overlapped, and the body side provided with the mounting base 11, the hollow sealing portion 17, and the lip 18 along the body flange 4 formed in the door opening. A weather strip 10 is attached. The hollow seal portion 17 elastically contacts the door sash 5 (front door sash) when the door is closed, and ensures a sealing property between the body panel 1 and the door sash 5. Moreover, the lip | rip part 18 contact | abuts the front-end | tip part to the vehicle interior garnish 6, and aims at the improvement of appearance.
[0013]
Further, in this mounting structure, the mounting base portion 11 of the weather strip 10 is formed by the sandwiching portion 16 and the base body 12. The clamping part 16 is formed of a vehicle interior part 16a that sandwiches the body flange 4, a vehicle exterior part 16c, and a connecting part 16b that connects the two. The base body 12 has a substantially U-shaped cross section including an upper wall 13 with a clip insertion hole 13a , a side wall 15 and a lower wall 14 , and is integrally formed with a sandwiching portion vehicle inner portion 16a .
[0014]
And, the mounting hole 2a is formed in Lee N'napaneru 2, by inserting the clip 7 into the insertion hole 13a and the mounting hole 2a, the mounting base 11 are fixed to the body flange 4 near the inner panel 2.
[0015]
Note that the mounting base 11 and the lip 18 are formed of a highly rigid material such as TPO or hard EPDM, thereby eliminating the need for embedding a cored bar. The hollow seal portion 17 is formed of a soft material such as foamed TPO or EPDM sponge rubber.
[0016]
In the mounting structure of the body side weather strip according to the present embodiment, since the mounting base 11 of the weather strip is fixed to the inner panel 2 of the body panel 1 by the clip 7, the weather strip 10 and the body panel 1 are fixed. Weight reduction can be achieved.
[0017]
That is, since it is fixed by the clip 7, it is not necessary to bury a cored bar, and the weather strip 10 can be reduced in weight. Moreover, since it is fixed to the inner panel 2, it is not necessary to secure a wide space for both the hollow seal portion 17 and the clip 7 on the outer panel 3 side by fixing to the conventional outer panel 3. The length of 4 can be set small. Therefore, the weight of the body panel 1 can be reduced.
[0018]
By fixing the mounting base 11 of the weather strip 10 to the inner panel 2, the height of the weather strip 10 can be set small while reducing the length of the body flange 4. The followability at the corner can be improved. Thereby, the workability | operativity of the weather strip 10 can be improved.
[0019]
Further, since the clip 7 is inserted and fixed through the insertion hole 13a and the attachment hole 2a, positioning at the time of attachment is easy. Furthermore, since it is fixed to the inner panel 2, the hollow seal portion 17 does not exist in this portion (the hollow seal portion 17 exists under the outer panel 3), so that a wide space can be secured. Therefore, the attachment work of the clip 7 and the weather strip 10 can be facilitated.
[0020]
Furthermore, since the mounting hole 2a through which the clip 7 is inserted is formed in the inner panel 2, unlike the outer panel 3, it is difficult for rain water and car wash water to adhere to it, thus preventing the occurrence of rust. can do.
[0021]
Further, the mounting base 11, the interior side of the substantially U-shaped section of the clamping portion 16 for clamping the body flange 4, the top wall 13, consists of side walls 1 5 and the lower wall 1 4 substantially U-shaped cross section of the base body Since 12 is formed by integral molding, high structural strength can be obtained. Therefore, the weather strip 10 can be firmly attached to the inner panel 2. Incidentally, if the side wall 15 is not provided, the structural strength of the mounting base 11 becomes fragile.
[0022]
A second embodiment of the body side weather strip mounting structure according to the present invention is shown in FIGS. The feature of this mounting structure is that the length of the portion forming the body flange 4 of the inner panel 2 is set to be shorter. Thereby, since the weight reduction of the body panel 1 can further be accelerated | stimulated, manufacturing cost can be reduced more.
[0023]
The mounting structure in the present embodiment is provided between the body panel 1 and the front door sash 5, but the present invention is not limited to this, and the rear door sash 5, the back door sash 5, or the trunk lid is not limited thereto. Etc. can also be provided.
[0024]
【The invention's effect】
In the body-side weather strip mounting structure according to the present invention, the mounting base 11 of the weather strip 10 is fixed to the inner panel 2 by the clip 7, so that no cored bar is required and the length of the body flange 4 is increased. Can be set small. Therefore, the weather strip 10 and the body panel 1 can be reduced in weight, and the manufacturing cost can be reduced.
[0025]
Further, since the clip 7 is inserted and fixed through the insertion hole 13a and the attachment hole 2a, positioning at the time of attachment is easy. Furthermore, since it secured to the inner panel 2 and the wide space for the clip 7 was ensured, the attachment operation | work of the clip 7 is easy.
[0026]
Furthermore, since the attachment hole 2a for inserting the clip 7 is formed in the inner panel 2, it is difficult for rain water and car wash water to adhere thereto. Therefore, Ru can be prevented from rusting from occurring.
