Abstract

PROBLEM TO BE SOLVED: To improve connecting rigidity of a pillar and an outrigger of an automobile body. SOLUTION: A reinforcing plate 7 is inserted between an inner panel 2 and an outer panel 3 constituting a pillar 1, and both edge parts of the reinforcing plate 7 are held between flange parts 2A, 3A at both edges of the inner panel 2 and outer panel 3 and welded to form the pillar 1. End flange parts 6A of an outrigger 6 are welded to the outside of the lower part inner panel 2 of the pillar 1, and the reinforcing plate 7 is bent onto the inner panel 2 side and welded to the inside of the inner panel 2 in the state of coinciding with the weld position of the end flange parts 6A of the outrigger 6. Connecting rigidity of the pillar 1 and outrigger 6 is therefore improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle pillar reinforcement structure.

[0002]

2. Description of the Related Art As shown in FIGS.
A side sill (4) is provided below the pillar (1) composed of the outer panel (3) and the pillar (1).
Outriggers (6) are inserted between the lower part of (1) and the side members (5), and the flanges (6A, 6B) at both ends of the outriggers (6) have inner panels (2) of pillars (1). And the outer surface of the side member (5). A reinforcing plate (7) is inserted into the pillar (1), and both edges of the reinforcing plate (7) are attached to the inner panel (2) of the pillar (1).
The flanges (2A, 2A) on both edges and the outer panel (3) are fixed by being sandwiched and welded between the flanges (3A, 3A) on both edges. The reinforcing plate (7) improves the rigidity of the lower body of the pillar (1) and the joint with the outrigger (6), and is transmitted to the pillar (1) via the side member (5) and the outrigger (6). The input from the mounted engine mount and suspension is suppressed, and the pillar (1)
Overall displacement (vibration) can be reduced.

[0003]

In the above conventional structure, as shown in FIG. 6, the flange portion (6A) of the outrigger (6) is joined to the side surface of the inner panel (2). ) There is a problem that the surface rigidity of the side surface is low and the coupling rigidity between the pillar (1) and the outrigger (6) is low.

[0004]

According to the present invention, as a means for solving the above-mentioned conventional problems, a reinforcing plate (7) is provided between an inner panel (2) and an outer panel (3) constituting a pillar (1). The lower inner portion of the pillar (1) which is inserted and welded by sandwiching both edges of the reinforcing plate (7) between the flange portions (2A, 3A) of both edges of the inner panel (2) and the outer panel (3). The outer flange (6A) of the outrigger (6) is welded to the outside of the panel (2), and the reinforcing plate (7) is further bent toward the inner panel (2), so that the outer flange (6) of the outrigger (6) is bent. 6A) To provide a reinforcing structure for the pillar (1) welded to the inner panel (2) inside to match the welding position.

[0005]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to one embodiment shown in FIGS. 1 to 3. A pillar (1) of an automobile is composed of an inner panel (2) and an outer panel (3). Side sills (4) are connected. An outrigger (6) extends between the lower part of the pillar (1) and the side member (5), and flange portions (6A, 6B) at both ends of the outrigger (6) are respectively provided in the pillar (1). It is welded to the outer surface of the lower inner panel (2) and the outer surface of the side member (5).

A reinforcing plate (7) is inserted into the pillar (1). As shown in FIG. 3, both edges of the reinforcing plate (7) are flanged at both edges of the inner panel (2). 2A, 2A) and outer panel
(3) The flanges (3A, 3A) of both edges are sandwiched and welded, and a predetermined portion of the reinforcing plate (7) is
(2) A bent portion (7A) is formed by bending to the side, and as shown in FIG. 1, the bent portion (7A) is aligned with the welding position of the flange portion (6A) at the end of the outrigger (6). Weld inside the inner panel (2).

[0007]

Therefore, according to the present invention, at the joint between the pillar (1) and the outrigger (6), the outrigger (6)
And the bent portion (7A) of the reinforcing plate (7) form a box-shaped coupling structure with the inner panel (2) interposed
(6) The surface rigidity of the inner panel (2) surface at the joint can be improved, the coupling rigidity between the pillar (1) and the outrigger (6) is improved, and the lateral falling rigidity of the pillar (1),
The rigidity of the entire vehicle body is improved.
