DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for connecting a center pillar and a side sill of an automobile.

[0002]

2. Description of the Related Art Conventionally, a connecting portion between a center pillar and a side sill of an automobile has been configured as shown in FIGS. Reference symbol a denotes a center pillar, which includes a center pillar outer panel a1 and a center pillar inner panel a2. b is a side sill, and a side sill outer panel b
1 and a side sill inner panel b2. c
Is a reinforcement that is sandwiched and joined between upper and lower edge flanges d1 and d2 of the side sill outer panel b1 and the side sill inner panel b2.

According to the above prior art, the lower edge of the center pillar outer panel a1 is joined to the upper outer surface of the side sill outer panel b1 to form the center pillar inner panel a2.
Is joined between lower ends of the side sill outer panel b1 and the side sill inner panel b2. Further, the reinforcement c is joined to the upper and lower edges of the side sill outer panel b1, and the box cross section A is formed below the center pillar a.
Is formed.

[0004]

According to the above-mentioned prior art, the center pillar a and the side sill b are formed separately and joined together to be integrally assembled. The box section of the side sill b is formed.

However, since the center pillar outer panel a1 and the center pillar inner panel a2 are assembled to the side sill outer panel b1 and the side sill inner panel b2 by joining, the rigidity between the center pillar a and the side sill b is insufficient. . Further, since the center pillar inner panel a2 is joined to the lower edge of the side sill outer panel b1, the upper portion is opened between the center pillar inner panel a2 and the reinforcement c, so that the vehicle body Bending,
Low torsional rigidity.

[0006] The present invention solves the above problems, to improve the bonding strength of the center pillar and the side sill body bending, Oyo <br/> Beauty, torsional rigidity the connection of a motor vehicle of the center pillar and the side sill obtaining aims to improve the It is intended to provide a partial structure.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a side body outer panel which also serves as a center pillar outer panel and a side sill outer panel, and a pair of side edges sandwiching a rear hinge hinge reinforcement.
A center pillar inner panel joined to both side edges of the center pillar outer panel portion of the side body outer panel, and a side sill inner panel joined to both side edges of the side sill outer panel portion of the side body outer panel with side sill strength for side sill reinforcement interposed therebetween.

[0008]

[Operation] The center pillar outer panel of the side body outer panel is joined to the center pillar inner panel via both side edges. At the same time, a rear hinge hinge reinforcement is joined at the same time. On the other hand, the side sill outer panel portion of the side body outer panel and the side sill inner panel are joined via both side edges. A side sill strength is simultaneously bonded between the two. Next, the lower end of the rear hinge hinge reinforcement is joined to the upper end of the side sill strength. In this way, two box cross sections are formed between the side sill inner panel and the side body outer panel with the side sill strength interposed therebetween.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings. 1 is a perspective view showing a vehicle body of an automobile, FIGS. 2A and 2B are perspective views showing a center pillar and a side sill portion of FIG. 1, FIG. 3 is an exploded perspective view of FIG.
5 is a sectional view of FIG.

1 to 5, a connecting portion between a center pillar 1 and a side sill 2 of an automobile includes a side body outer panel 3 serving also as a center pillar outer panel and a side sill outer panel;
Center pillar inner panel 4 in which both side edges 4a are joined to both side edges 3a of the center pillar outer panel portion 31 of FIG.
A side sill inner panel 5 in which both side edges 5a are joined to both side edges 3b of a side sill outer panel portion 32 of the side body outer panel 3, and a side sill inner extension in which a lower end of the center pillar inner panel 4 and an upper end of the side sill inner panel 5 are joined. 6 form an external structure.

On the other hand, the reinforcing structure is a rear hinge hinge reinforcement 7 which is simultaneously joined between the center pillar outer panel portion 31 of the side body outer panel 3 and the center pillar inner panel 4 via both side edges 7a.
Between the side sill outer panel portion 32 of the side body outer panel 3 and the side sill inner panel 5;
side sill strength 8 simultaneously joined through a
The side edges 9a are joined along the inner surface of the side sill outer panel portion 32 of the side body outer panel 3 and between the lower end of the rear hinge hinge reinforcement 7 and the upper end of the side sill strength 8 in the center pillar 1 portion. is composed of a center pillar Roari over emissions reinforcement 9.

Reference numeral 10 denotes a main floor panel, and a side edge 10a is joined to the side sill inner panel 4. In addition,
The main floor panel 10 is, as shown in FIG.
And a 0b raised, the upper end 10b1 of the side edge portion 10b joined to the upper edge 8a of the side sill Strength 8, the side edge 10 b
Joins the lower end 10b2 on the lower edge 3b of the side sill outer panel portion 32 of the side body outer panel 3 may be omitted side sill inner panel 4.

According to the above configuration, since the connecting portion between the center pillar 1 and the side sill 2 is formed by using the side body outer panel 3 which also functions as the center pillar outer panel and the side sill outer panel, the rigidity of the connecting portion is improved.
The center pillar 1 has a center pillar at the lower end.
Box cross sections A and B are formed on both sides of the side sill strength 8 using the lower reinforcement 9. Thus, since the box section of the side sill 2 is also continuous in the center pillar 1 below, of the body bending, and,
The torsional rigidity is improved.
