Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile side body structure capable of improving strength.

[0002]

2. Description of the Related Art FIG. 6 shows an upper end portion of a center pillar portion 100 of a conventional automobile, and usually includes a center pillar inner panel 101 and a side body outer panel 10.
A center pillar portion 100 is formed with the second pillar portion 103, and a center pillar reinforcement 104 is provided inside the center pillar portion 100 for reinforcement. The upper ends of the center pillar inner panel 101, the pillar portion 103 of the side body outer panel 102, and the center pillar reinforcement 104 are joined to both sides of the roof panel 105. The upper end portion 104a of the center pillar reinforcement 104 is formed wide in the front-rear direction of the vehicle body, and a step portion 106 is formed at a front end portion in the vehicle width direction as shown in FIG. A roof side reinforcement 1 for reinforcing the roof side is provided on the edge 107 of the wide upper end 104a.
08 are joined. The step 106 at the upper end of the center pillar reinforcement 104 is joined to the roof panel 105 and assembled.

[0003]

In the above-mentioned conventional side body structure, a roof side reinforcement 108 for reinforcing a roof side is joined to an edge 107 of an upper end 104a of a center pillar reinforcement 104. Therefore, the strength and rigidity of the upper end portion of the center pillar portion 100 were insufficient for the impact load F from the front and side surfaces.

[0004] It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a side body structure of an automobile capable of improving strength.

[0005]

According to the present invention, in order to solve the above-mentioned problems, a side body is constituted by an inner panel and a side body outer panel, and a reinforcement for reinforcing a center pillar portion is provided at a center pillar portion of the side body. In this structure, a reinforcement for reinforcing the roof side is extended in the front-rear direction of the vehicle and is disposed so as to intersect the center pillar. Then, the reinforcement for reinforcing the roof side and the reinforcement for reinforcing the center pillar portion are joined to each other to improve strength and rigidity. Further, in the present invention, a sub-reinforcement forming a closed cross section is joined to the reinforcement for reinforcing the roof side to improve the rigidity on the upper side of the center pillar portion. Further, in the present invention, an upper end portion of the reinforcement for reinforcing the center pillar portion is formed in a rectangular shape, and the reinforcement for reinforcing the roof side is joined so as to overlap the rectangular portion. Then, the sub reinforcement is joined to the inner surface side of the reinforcement for roof side reinforcement to form a closed cross section,
Improve the rigidity of the center pillar.

Thus, the rigidity of the upper portion of the center pillar portion can be improved, so that the rigidity against the impact load from the front and side surfaces can be improved.

[0007]

Embodiments of the present invention will be described below in detail with reference to the drawings.

1 to 5, reference numeral 1 denotes a vehicle body of an automobile. A side body 4 having a front door 2 and a rear door 3 is provided on a side surface of the vehicle body 1. In the side body 4, a center pillar portion 5 is provided in the middle of a door opening where the front door 2 and the rear door 3 are provided. In the side body 4, a center pillar reinforcement 9 is provided between an inner panel (center pillar inner panel) 6 provided on the indoor side and a pillar portion (center pillar outer panel) 8 of a side body outer panel 7 provided on the outdoor side. Have been.

The upper end 6a of the inner panel 6 and the upper end 7a of the side body outer panel 7
The interior trim 11 and the molded ceiling member 12 are arranged on the indoor side of the inner panel 6 and the roof panel 10 by joining them together by spot welding w to the side edge portion 10a. The center pillar reinforcement 9 has an upper end formed in a rectangular shape, and an extension 14a of a roof side reinforcement 14 for reinforcing the roof side of the roof panel 10 is joined to the rectangular portion 13. I have. Roof Side Reinforcement 1
As shown in FIG. 5, the reference numeral 4 is formed to extend rearward of the vehicle body by a predetermined length L, and is formed in a rectangular shape so as to match the upper end rectangular portion 13 of the center pillar reinforcement 9. I have. In the roof side reinforcement 14, a step 15a extending in the vehicle width direction is formed on a side surface of the rectangular portion 15, and this step 15a is joined to the roof panel 10 together with the side body outer panel 7 and the inner panel 6. are doing.

[0010] The roof side reinforcement 1
4 is disposed so that the extension portion 14a intersects the upper end rectangular portion 13 of the center pillar reinforcement 9 and has a U-shaped cross section inside the rectangular portion 15 of the roof side reinforcement 14. The sub reinforcement 16 is joined. The sub reinforcement 16 is a U-shaped long member provided with flange portions 16a and 16b at upper and lower portions.
Roof side reinforcement 14 through 16b
Is joined to the inner surface of the rectangular portion 15.

According to the above construction, the roof side reinforcement 14 is formed by extending the predetermined length L, and the extension 14 of the roof side reinforcement 14 is formed.
Since a is arranged so as to overlap the upper end rectangular portion 13 of the center pillar reinforcement 9, the rigidity of the upper portion of the center pillar portion 5 can be improved against an impact load from the side. Further, since the sub-reinforcement 16 is joined to the rectangular portion 15 of the roof side reinforcement 14 to form the closed cross-sectional shape S1, the rigidity of the upper portion of the center pillar portion 5 can be improved. Further, a step 15a extending in the vehicle width direction is formed in the rectangular portion 15 of the roof side reinforcement 14, and this step 15a is joined to the roof panel 10 together with the side body outer panel 7 and the inner panel 6. Since the closed cross-sectional shape S2 is formed by the roof side reinforcement 14, the inner panel 6, and the sub-reinforcement 16, two closed cross-sections are formed together with the closed cross-sectional shape S1 to improve rigidity. Can be planned.

The present invention is not limited to the above embodiment. For example, the length L of the extension 14a of the roof side reinforcement 14 may be set as required, and The length of the element 16 can also be set arbitrarily. The rigidity of the sub reinforcement 16 can be improved by inserting ribs and the like as necessary. Needless to say, the present invention can be appropriately changed and implemented within a scope that does not change the gist of the present invention.

[0013]

As described above, according to the vehicle side body structure of the present invention, the following effects can be obtained. A side body is composed of an inner panel and a side body outer panel. Since it was extended and arranged so as to intersect with the center pillar, the reinforcement for reinforcing the roof side and the reinforcement for reinforcing the center pillar were joined to each other.
The rigidity of the upper part of the center pillar can be improved. Since the sub reinforcement for forming the closed cross section is joined to the reinforcement for reinforcing the roof side, the rigidity of the upper portion of the center pillar can be improved. An upper end portion of the reinforcement for reinforcing the center pillar portion is formed in a rectangular shape, and the reinforcement for reinforcing the roof side is joined so as to overlap with the rectangular portion, and the reinforcement for reinforcing the roof side is formed. Since the sub-reinforcement is joined to the inner surface of the element to form a closed cross section, the rigidity of the upper portion of the center pillar can be improved.
