Description

[Detailed Description of the Invention] The present invention relates to a connection structure between a front pillar and a cowl top that has improved waterproofness in an automobile body structure.

A front pillar portion 01 of a vehicle body shown in FIG. 1 generally has a conventional structure shown in FIG. 2. FIG. 2 is a cross-sectional view of the front pillar part 01 taken along the line A-A in FIG. are arranged to face each other, and the side ends of a cowl top inner panel 04 are covered above these, and an upper frame extension 05 is attached to the upper surface of the cowl top inner panel 04. Here, front pillar outer row 02, front pillar narrow 03 and Atsupa frame extension 05
Flanges 02a, 03a, 05a are provided at the side ends of the
is formed, and the cowl top inner panel 0
The flanges 02a, 03a,
05a are provided facing each other and are integrally joined by spot welding.

By the way, in the above conventional structure, the flange 03a at the upper end of the front pillar narrow 03 which forms the joint surface with the cowl top panel 04, and the flange at the side end of the front pillar narrow 03 which forms the joint surface with the front pillar outer row 02. Since these are formed separately, there is a problem in that the seals break at the separated parts, reducing waterproofness.

The present invention solves the above-mentioned problems of the conventional technology and provides a highly waterproof car body structure, which consists of a front pillar narrow and a narrow front pillar arranged substantially parallel to each other along the longitudinal direction of the car body. a front pillar portion formed by a front pillar outer row; and a cowl top panel coupled to an upper end portion of the front pillar outer row and an upper end portion of the front pillar outer row along the vehicle width direction. At the front end of the front pillar narrow, a first
forming a flange, and bending the vicinity of the front end of the front pillar narrow toward the front pillar outer row so that the first flange abuts the side of the front pillar outer row;
A second flange coupled to the cowl top panel is formed at the upper end of the front pillar narrow, and the second flange and the first flange are continuously provided.

The present invention will be explained in detail below based on an embodiment shown in the drawings.

FIG. 3 shows a cross-sectional structure of a connecting portion according to the present invention, and FIG. 4 shows an outline of its assembled state. As shown in the figure, the front pillar outer tallow 2 and the front pillar narrow 3 are arranged to face each other, and a front pillar inner upper 7 is installed inside them. A cowl top inner panel 4 is provided on the upper part of these front pillar outer row 2, front pillar narrow 3, and front pillar inner upper part 7 so as to cover them, and furthermore, an upper frame extension 5 is arranged on the upper surface of the cowl top inner panel 4. be done. Flanges 2a, 3a, 3b, 5a are formed at the side ends of the front pillar outer row 2, front pillar narrow 3, and upper frame extension 5, respectively, and these flange portions 2a, 3
a, 3b, and 5a are integrally joined by spot welding. Here, the first flange 3b formed at the side end of the front pillar narrow 3 and the second flange 3a formed at the upper end thereof are the joint surfaces with the cowl top inner panel 4 or the front pillar outer row 2, respectively. In the present invention, the second flange 3a at the upper end wraps around toward the front pillar outer row 2 as shown in FIG. 4, and extends until it comes into contact with the inner peripheral surface of the front pillar outer row 2. The second flange 3a at the upper end and the first flange 3b at the side end are continuously and integrally formed.

According to the coupling structure of the present invention, the second flange 3a coupled to the cowl top inner panel 4 is formed at the upper end of the front pillar narrow 3, and the front pillar outer is formed at the front end of the front pillar narrow 3. Since the first flange 3b that comes into contact with the tallow 2 is formed and the first flange 3b and the second flange 3a are provided continuously, when the sealer material 6 is provided on the flange, the sealer material 6
can be arranged continuously from the upper end of the front pillar narrow 3 where the cowl top inner panel 4 is connected to the front end where it comes into contact with the front pillar outer row 2, preventing sealer breakage and reducing the front pillar narrow 3. This has the effect of improving waterproofness between the inside and outside.

In this case, if a sealer reservoir 6a is formed in the flange 2a of the front pillar outer row and used in combination with the joint structure of the present invention, waterproofness can be further improved.
