Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a pillar structure of an automobile.

BACKGROUND ART Conventionally, in a car equipped with a door mirror 2 at the corner of a window 1, as shown by line A in FIG. Some models are equipped with door mirror 2.

At the installation location, the corner cover is assembled by receiving the edge of the corner cover inside the weather strip retainer (hereinafter simply referred to as "retainer") that is attached to the pillar panel and holds the weather strip. This is usually the case.

This pillar structure that accepts the edge of the corner cover is constructed by assembling retainers, weather strips, etc. that have the same cross-sectional shape as the area that accepts the edge of the corner cover and other general areas. Then, the edge of the corner cover interferes with the weather strip, causing the weather strip to be partially pressed and deformed. By bulging out laterally, the deformed portion of the weather strip can avoid pushing and expanding the drip molding, which bulges out from the side of the retainer along the pillar panel, together with the flange portion located on the outer side of the retainer. do not have.

To avoid this, when forming weather strips, retainers, etc. by extrusion molding or roll forming, the cross-sectional shape of the part that receives the edge of the corner cover can be formed differently from the general part.
The modification of the cross-sectional shape cannot be carried out at the same time as the usual extrusion molding or roll molding that forms the weather strip and retainer in general parts, so it must be processed separately.

Problems to be Solved by the Invention The present invention changes the shape of the assembly part of the corner cover from the general part and places the edge of the corner cover inside the retainer without requiring any special effort or detracting from the appearance. The purpose is to provide an improved pillar structure for automobiles.

Means for Solving the Problems In the automobile pillar structure according to the present invention,
The base of the weather strip is fitted and held in the channel part of the retainer installed along the pillar panel, and each flange on the inside and outside of the vehicle is continuously bent outward at a predetermined angle from the channel part of the retainer. a general part that supports both sides of the weather strip at the outer side of the weather strip, and further hides a gap between the weather strip and the drip molding protruding along the pillar panel at the flange part on the outside of the vehicle; In addition to the above configuration, the retainer has a corner cover assembly part in which the edge of the corner cover attached to the corner part of the window is brought into contact with the weather strip and is received and arranged in the flange part of the retainer. It is integrally formed over the entire length from the general part to the corner cover assembly part, and at the corner cover assembly part, the flange part on the outside of the vehicle is bent closer to the channel part than the general part, and the flange part The distal end side of the flange portion is located closer to the channel portion than the distal end side of the flange portion on the outside of the vehicle in the general portion, and is assembled so as to abut against the drip molding so as to hide the gap between the drip molding and the drip molding.

Function: In the pillar structure of this automobile, the outer side flange of the retainer is bent toward the channel part than the general area at the corner cover assembly area, and the tip side of the flange is bent into the outer side flange of the retainer at the general area. By locating the weather strip closer to the channel side than the tip side of the weather strip, there is a space that allows the weather strip to bulge and deform, so not only does the bending process require no special effort.
The bent portion of the retainer is not exposed to the outside, and the gap between the retainer and the drip molding is hidden on the distal end side, so that the retainer can be kept in a good appearance.

Embodiments The following description will be made with reference to FIGS. 1 to 4.

FIG. 1 shows one side of the window plate 10 as well as a front side pillar structure that is received near the edge and lower end of a corner cover 11 that is disposed to mount a door mirror.

In this pillar structure, B- in FIG. 1 shown in FIG.
The cross section of the retainer 21 that holds the weather strip 20 at the general part corresponding to the cross-sectional area taken along the line B and the assembly part of the corner cover 11 corresponding to the cross-sectional area taken along the line C--C in FIG. 1 shown in FIG. It is constructed by changing the shape of the surface from part to part. As shown in FIGS. 2 and 3, the pillar structure is such that a retainer 21 that holds the weather strip 20 is attached to a pillar panel 22, and a drip molding 23 fixed to this retainer 21 is attached to the pillar panel 22 from the side of the retainer 21. The weather strip 2 is placed in a bulging position along the
The edge 20a curved from the retainer 21 of 0 is locked with a door opening trim 26 attached to the joint portion of the pillar panel 22 and the door panel 25.

The weather strip 20 is made of rubber.
A material made of an elastic material such as foamed resin can be used. The weather strip 2
The retainer 21 that holds 0 is made by integrally bending a metal plate material by roll forming over the entire length from the general area to the assembly area of the corner cover 11. Further, this retainer 21 has a channel portion 21a having a substantially C-shaped cross section that holds the base of the weather strip 20, a flange portion 21b on the outside of the vehicle, and a flange portion 21c on the inside of the vehicle, which are continuous from the channel portion 21a. It is formed to exhibit a predetermined cross-sectional shape by bending outward at a predetermined angle. The retainer 21 has a synthetic resin cushioning material 2 that comes into contact with the drip molding 23.
1d is attached along the tip side of the flange portion 21b located on the outside of the vehicle.

On the pillar side, the corner cover 11 includes an outer cover part 11a and an inner cover part 11b as shown in FIG.
1b is integrally supported by the holding portion 11c, and
The holding part 11c is fixed to the door side with a bracket 11d into which the glass launch channel 12 is fitted, so that it is hung over the front pillar and the door.

This corner cover 11 has one side attached to the flange portion 2 of the retainer 21 so that the weather strip 20 held by the retainer 21 is pressed and deformed.
b, 21c. Along with this, the weather strip 20 partially bulges out to the side, but the retainer 21 at the assembly site of the corner cover 11 bends the flange portion 21b on the outside of the vehicle as shown from the broken line to the solid line in FIG. In addition, by locating the tip end side of the flange portion 21b closer to the channel portion 21a than the flange portion 21b on the outside of the vehicle in the general portion, the interval between the flange portions 21b and 21c is set relatively wider than in the general portion. Therefore, the bulging portion of the weather strip 20 can be tolerated.

That is, in the cross section of the general portion of FIG. 3, the flange portion 21 on the outside of the vehicle that projects obliquely from the channel portion 21a at an angle θ is bent toward the channel portion 21a until the angle θ approaches approximately zero;
The flange portion 21 is bent so that the angle α of the approximately middle side between the channel portion 21a side and the tip side of the flange portion 21 approaches a right angle.
The distance between b and 21c is relatively wider than that of the general portion. The bending can be done by simply pushing and bending the flange part 21b on the outside of the vehicle toward the channel part 21a, so the flange part 21b was kept in a broken line shape and the whole was bent by roll forming to match the shape of the general part. After that, it can be easily deformed by bending only the necessary portions into a solid line shape in a separate process.

In order to accommodate this bending, the drip molding 23 is fixed to the channel portion 21a of the retainer 21 as shown in FIG. It is attached so that it bulges out from the bottom side to the sides while maintaining the same shape. At the separated location, the flange portion 21b of the retainer 21 on the outside of the vehicle is bent relatively deeply and is located close to the side surface of the drip molding 23, so that the weather strip 2
By coming into contact with the bulge portion of 0, the gap between the two is hidden. Further, since the cushioning material 21d is attached to the distal end side of the flange portion 21b, this gap has a relatively large width, so that it can be completely hidden from view from the outside.

Effects of the invention As described above, according to the automobile pillar structure according to the invention, even if the edge of the corner cover is accepted between the flange portions of the retainer, the bulging deformation of the weather strip due to the acceptance is prevented by the retainer. Since the retainer can be easily tolerated through simple shape deformation, it does not increase manufacturing costs, and the deformed part of the retainer is not exposed to the outside, and the gap between the retainer and the drip molding can be hidden, so it can be maintained in a good appearance. I can do it.
