Description

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

b. Prior Art In the conventional rear pillar structure for automobiles, the rear part of the side panel is bent inward at a right angle, and the rear edge is bent inward at a substantially right angle to form a U-shaped cross section. However, one side of the rear pillar outer panel was spot welded to the inner surface of the inner recess of this U-shaped cross section.

c Problems to be solved by the invention As mentioned above, in the past, from the viewpoint of the appearance of the car body, one side of the rear pillar outer panel was covered at the rear of the side panel.
There are problems in that it is not easy to form (draw) the rear part of the side panel, and it takes time and effort to assemble the two panels. The present invention was developed to solve these problems, and its purpose is to make the side panels very easy to form and assemble, and to have an excellent appearance. To provide a rear pillar structure for an automobile which can obtain a design, can sufficiently correspond to the design of the automobile, and also has a rust-preventing effect.

d Means for Solving the Problems In order to solve the above-mentioned problems, in the present invention, a stepped portion is provided in the bent portion formed at the rear end of the side panel, so that the rear end edge is The garnish is disposed rearward from the bent portion, an engagement hole is formed in the rear edge, one end of the rear pillar outer panel is connected to the inner surface of the bent portion, and the garnish has a substantially U-shaped cross section. By inserting an engaging protrusion provided therein into the engaging hole and engaging it, it is attached to the joint between the side panel and the rear pillar outer panel.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Figure 1 shows the rear corner of a car. In the figure, 1 is a side panel, 2
3 is a roof panel, 4 is a back door assembly, 5 is a drip molding attached to both sides of the roof panel 3, and 6 is a side panel 1.
Garnishes are attached to both sides of the back door assembly 4 at the rear end, 7 is a rear pillar outer panel, and 8 is a rear combination lamp.

The upper part 1a of the above-mentioned side panel 1 is bent inward at a substantially right angle, and furthermore, its tip 1b is bent upward at a substantially right angle. Also,
The periphery of the roof panel 3 is bent downward, and a recess 9 having an L-shaped cross section is formed on both sides of the vehicle body by the side part 3a of the roof panel 3 and the upper part 1a of the side panel 1. . The recess 9 and the vertical end edge 1b of the side panel 1 extend halfway into the corner 10 at the rear of the vehicle body.

The drip molding 5 has a notch 5a extending in the longitudinal direction at its bottom.
The vertical tip edge 1b described above is inserted into the recess 9, whereby the drip molding 5 is installed in the recess 9 with its position restricted.

On the other hand, as shown in FIGS. 1 and 2, a right-angled bent portion 1c is formed at the rear part of the side panel 1 over the entire length of the upper and lower sides, and an approximately right-angled bent portion 1c is formed rearward at the edge of this bent portion 1c. Step part 1 bent into
d is formed, and furthermore, a bent piece 1 is bent inward at a substantially right angle to the edge of the stepped portion 1d.
e is formed. However, the stepped portion 1d
A protruding portion 11 that protrudes rearward by the bent piece 1e.
This protrusion 11 is arranged in a recess 12 formed at both corners at the rear of the vehicle body.

Then, as shown in Fig. 2, the side panel 1
The bent edge 7a of the rear pillar 7 is joined to the inner surface of the bent portion 1c by spot welding or the like, and the bent piece 1e of the side panel 1 is arranged substantially parallel to the bent edge 7a at a distance. ing. Also,
As shown in FIG. 2, the other end edge 7b of the rear pillar outer panel 7 is joined to the inner panel 13 by spot welding or the like. Further, the rear end of the roof panel 3 and the upper end of the rear pillar outer panel 7 are joined together by brazing, arc welding, etc. in a superposed state as shown in FIG. 3.

Further, as shown in FIGS. 1 and 2, a plurality of engagement holes 14 are formed at predetermined intervals in the bent piece 1e of the side panel 1, and the garnish 6 is inserted using these engagement holes 14. It is adapted to be installed within the recess 12. That is, the garnish 6 is made of an integrally molded resin product and has a substantially U-shaped cross section, and an engaging protrusion 16 having a large diameter head 15 is provided in the recess 6a.
The garnish 6 is installed in the recess 12 by pushing the large-diameter heads 15 of these engaging protrusions 16 into the engaging holes 14 and click-engaging them.

Next, to describe an example of assembling the vehicle body, first, the side panel 1 and the rear pillar outer panel 7 are assembled as shown in FIG. 7 is assembled as shown in FIG. 3, and then the drip molding 5 and garnish 6 are installed in the recesses 9 and 12, respectively, as described above. In this case, since the outer surface of the upper end of the garnish 6 is formed so as to be continuous with the outer surface of the rear end of the drip molding 5 at the corner section 10 at the rear of the vehicle body, there is a step at the joint between these two at the corner section 10. It becomes a continuous surface without causing any turbulence.

According to such a rear pillar structure, in order to attach the garnish 6, the step portion 1d and the bent piece 1e can be formed on the side panel 1 by a simple bending process, so that the formability (drawability) of the side panel can be improved. Moreover, the panels 1 and 7 can be easily assembled. Further, the garnish 6 can be easily attached and fixed by using the engagement hole 14 provided in the bent piece 1e of the side panel 1. Also, side panel 1
During the spot welding work of the rear pillar outer panel 7, the stepped portion 1d can be used as a guide opening, making the work easier. Moreover, even if such a step 1d is formed, since this portion is eventually covered with the garnish 10, there is no risk of spoiling the appearance of the vehicle body.

Although one embodiment of the present invention has been described below, the present invention is not limited to the embodiment described above, and various modifications and changes can be made based on the technical idea of the present invention.

For example, the stepped portion 1d and the bent piece 1e of the side panel 1 do not necessarily have to be bent at right angles, but may be bent at any angle. Furthermore, the shape of the engaging protrusion 16 formed on the garnish 6 can be changed as appropriate.

e Effects of the invention As described above, the invention provides a step and a bent piece located at the rear of the vehicle body at the bent part at the rear of the side panel, and the garnish is attached using the engagement hole formed in this bent piece. Because it is a thing,
Forming of the side panel requires only a simple bending process, which improves formability and facilitates assembly of the vehicle body. Further, since the panel joint portion is covered with the garnish, it is possible to improve the design of the external appearance and to improve the rust prevention properties of the panel joint portion. Furthermore, since the exterior design and ease of assembly of the vehicle body are improved, various variations such as a high roof can be accommodated.
