Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a reinforcing structure for a targa roof vehicle, which is constructed by connecting a rear roof with a portion of the roof left in the form of a roll bar to a body pillar.

[Conventional technology]

Conventionally, the body structure of the rear roof and body pillar of a targa roof vehicle, in which a rear roof with a portion of the roof left in the form of a roll bar is connected to a body pillar, is as shown in FIGS. 6a and 6b.
Outer panel 1a and inner panel 1 of rear roof 1
quarter outer 6a and quarter inner 6b of the quarter panel 6 that constitutes the body pillar 2
It forms part of a roll bar with a box-shaped cross section.

Further, as shown in FIGS. 7 and 8, there is no reinforcement having a box-shaped cross section in the longitudinal direction of the vehicle at the joint portion 9 between the corner portion 12a of the rear roof 1 and the quarter panel 6.

[Problem that the invention attempts to solve]

However, in the case of FIGS. 6a and 6b, the thickness of the outer panel 1a of the rear roof 1 and the quarter outer 6a of the quarter panel 6 is increased, resulting in a significant increase in cost and weight. In the case of FIG. 8, with the normal plate thickness, the joint strength and rigidity of the joint portion 9 between the corner portion 12a of the rear roof 1 and the quarter panel 6 are insufficient.
Furthermore, there is also a problem in the rigidity of this joint portion 9 in the longitudinal direction of the vehicle.

Therefore, the problem that this invention aims to solve is to increase the thickness of each member constituting the outer panel 1a of the rear roof 1, the quarter outer 6a of the quarter panel 6, the roll bar 4, and the side roll bar 7. In addition to improving body strength and rigidity, the corner part 12 of the rear roof 1
The purpose of this invention is to improve the bonding strength of the bonding portion 9 between A and the quarter panel 6, as well as the rigidity of this bonding portion 9 in the longitudinal direction of the vehicle.

[Means for solving the problem] Therefore, this invention solves the above-mentioned problem by setting a reinforcement at the joint part of the rear roof corner and the quarter panel, adjacent to the roll bar and the side roll bar. This is what we are trying to solve.

More specifically, referring to the reference numerals shown in FIG.
A roll bar 4 having a box-shaped cross section is disposed and coupled within the rear roof 1, and a side roll bar 7 having a box-shaped cross section is connected to the roll bar 4 within the body pillar 2. In a targa roof vehicle that is arranged and combined, a rear roof is placed adjacent to each box-shaped cross section of the connected roll bar 4 and side roll bar 7 in each box-shaped cross section of the connected rear roof 1 and body pillar 2. One end 80 of the reinforcement 8 is connected to the joint part 9 between the corner part 12a of the outer panel 1a and the quarter outer 6a of the quarter panel 6 constituting the body pillar 2, and the other end 81 of the reinforcement 8 is connected to the body pillar 2. It is connected to the quarter inner 6b of the quarter panel 6 to form a box-shaped cross section, and the box-shaped cross section, which is different from the roll bar 4 and the side roll bar 7, is connected to the joint portion 9 by a reinforcement 8. It was formed in

[Effect]

According to the above-mentioned means, the roll bar 4 and One end 80 of a reinforcement 8, which is a separate member, is welded adjacent to the side roll bar 7, and the other end 81 of the reinforcement 8 has a box-shaped cross section on the quarter inner 6b of the quarter panel 6 shown in FIG. Since another box-shaped cross section is formed by the reinforcement 8 adjacent to the roll bar 4 and the side roll bar 7, the rear roof 1
The joint strength and rigidity of the joint portion 9 between the corner portions 12a, 2a and the quarter panel 6 are improved.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings. The drawings from Figure 1 to Figure 4b are as follows:
This figure shows an embodiment of this invention, and as can be seen in FIG. As can be seen from FIG. from the outer panel 1a of the rear roof 1, and
The outer panel 1 of the rear roof 1 is spot-welded and welded to the flange 10a of the outer panel 1a of the rear roof 1.
A flange 50 of the back door frame 5 formed into a box-shaped cross section by the back door frame upper 5a and the back door frame lower 5b, separated from the back door frame 5a.
, the flange 1 of the outer panel 1a of the rear roof 1
It is spot welded to 1a.

On the other hand, as can be seen from FIG. 5b, the quarter panel 6 constituting the body pillar 2 is formed into a box-shaped cross section with a quarter outer 6a and a quarter inner 6b. One end 70 of the side roll bar 7 is spot welded to the flange 60b, and
The other end 71 of the side roll bar 7 is welded to the quarter inner 6b so as to form a box-shaped cross section, and the side roll bar 7 is attached to the quarter panel 6.
It is set in the interior 60a of the quarter outer 6a, separated from and independent of the quarter outer 6a.

As can be seen from FIG. 1, a reinforcement formed in the longitudinal direction of the vehicle extends to the joint between the end 40a of the roll bar upper 4a of the roll bar 4 and the end 72 of the side roll bar 7. 8, one end 80 of which is clearly visible in FIG. 2, is a quarter panel 6 constituting the body pillar 2.
The end 60a of the quarter outer 6a, the end 40a of the roll bar upper 4a, and the end 72 of the side roll bar 7 (see FIG. 3) are rigidly welded by spot welding or the like. The side roll bar 7 is welded to the outer panel 1a of the rear roof 1 and a quarter panel 6 constituting the body pillar 2. Furthermore, the other end 81 of the reinforcement 8 is welded by spot welding or the like to the quarter inner 6b of the quarter panel 6 constituting the body pillar 2 so as to form a box-shaped cross section, thereby improving the rigidity of the rear body 3.

That is, adjacent to each box-shaped cross section of the roll bar 4 and side roll bar 7 that are connected to each other within each box-shaped cross section of the rear roof 1 and body pillar 2 that are connected to each other, another box-shaped cross section is attached to the reinforcement 8. By forming this in the bonding site 9, the bonding strength and bonding rigidity of the bonding site 9 can be greatly improved.

Therefore, by setting the thickness of the small members of the roll bar 4, side roll bar 7, and reinforcement 8 to be thicker than that of the outer panel 1a and the quarter outer 6a, the joint rigidity can be further improved. Of course.

As mentioned above, the reinforcement 8 is also rigidly connected to the quarter outer 6a of the quarter panel 6, and the roll bar 4 is also rigidly connected to the outer panel 1a of the rear roof 1. The outer panel 1a and the quarter outer 6a also contribute effectively to body strength and rigidity.

[Effect of idea]

As mentioned above, this invention rigidly welds and connects reinforcements that form another box-shaped cross section adjacent to the roll bar and side roll bars to the joint area between the corner part of the rear roof and the quarter panel. Because it is not necessary to increase the thickness of the outer panel of the rear roof and the quarter outer of the quarter panel, there is no significant increase in cost or weight, and the strength of the connection between the rear roof corner and the body pillar connection area and the rigidity in the longitudinal direction of the vehicle are improved. It is possible to significantly improve the rigidity of the targa roof joining area.
