DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to assembling a side body of an automobile .
It relates to only process, automobile side body with particularly a front pillar reinforcement and the center pillar reinforcement
Related to the assembly method .

[0002]

2. Description of the Related Art Conventionally, in a side body structure of an automobile, FIG.
As shown in FIG. 1, there is known a structure including a side outer 78 formed integrally with a front pillar outer portion 70, a roof rail outer portion 72, a rocker outer portion (also referred to as a side sill outer portion) 74, and a center pillar outer portion 76. One example is shown in Japanese Utility Model Laid-Open No. 60-157374.

In this vehicle side body structure, when reinforcing the front pillar outer portion 70 of the side outer 78, a front pillar reinforcement 80 is provided inside the front pillar outer portion 70 in the vehicle width direction.
When reinforcing the center pillar outer portion 76 of the side outer 78, a center pillar reinforcement 82 is provided inside the center pillar outer portion 76 in the vehicle width direction.

[0004]

However, in such a side body structure of an automobile, since the front pillar reinforce 80 and the center pillar reinforce 82 are separated from each other, it is difficult to improve the rigidity of the entire vehicle body. Therefore,
The front pillar reinforce 80 and the center pillar reinforce 82 may be connected by a rocker reinforce 84 disposed inside the rocker outer portion 74 in the vehicle width direction. In this case, the front pillar reinforce 80 and the center pillar reinforce 80 are connected. Due to the variation in the joints between the rocker reinforcements 82 and the rocker reinforcements 84, it is extremely difficult to determine the positional accuracy of the front pillar reinforcement 80 and the center pillar reinforcement 82 in the vehicle longitudinal direction.

In view of the above, an object of the present invention is to provide a method of assembling a side body of an automobile which can easily obtain the positional accuracy of a front pillar reinforce, a center pillar reinforce, and a rock reinforce.

[0006]

Means for Solving the Problems The present onset light according to claim 1
A front pillar outer, a rocker outer, and a center pillar outer are integrated, and a first side reinforcing body composed of a center pillar reinforce and a rock reinforce; and the first side reinforcing body composed of a front pillar reinforce the second and the side reinforcing member of said first side portion reinforcing member and the second side portion reinforcing member and the side structures and automotive side vehicle body that is composed to be integrated combined with set
A saw with a method, the center pillar reinforcement and pre-coupled to the rocker reinforcement, the front pillar reinforcement and the said rocker reinforcement bound with a flange surface extending in the longitudinal direction of the vehicle body, said first to said side structure The front pillar reinforce and the first side reinforcement are relatively moved in the vehicle longitudinal direction in a state where the side reinforcement and the second side reinforcement are assembled, and the front pillar reinforce and the center are moved. The front pillar reinforce and the first side reinforcing member are coupled at a position where the positioning with the pillar reinforce can be reliably performed.

According to a second aspect of the present invention, there is provided a method of assembling a side body of a vehicle according to the first aspect, wherein the flange surface is shifted in a vehicle width direction. It is characterized in that two or more surfaces are formed.

[0008]

According to the first aspect of the present invention, there is provided a vehicle side body assembly according to the present invention.
In the mounting method , a front pillar reinforce of the second side reinforcement and a rock reinforce of the first side reinforcement composed of a center pillar reinforce and a rock reinforce, which are pre-coupled, are connected to a flange surface extending in the vehicle longitudinal direction. With the first side reinforcement and the second side reinforcement incorporated in the side structure, the front pillar reinforce and the first side reinforcement are opposed in the vehicle longitudinal direction. Then, the front pillar reinforce and the first side reinforcement are joined at a position where the positioning between the front pillar reinforce and the center pillar reinforce has been securely performed. Therefore, it is possible to easily obtain the positional accuracy of the front pillar reinforce, the center pillar reinforce, and the rock reinforce.

Further, the side vehicle-body assembly method of the vehicle according to the present invention described in claim 2, in side vehicle-body assembly method of the vehicle according to the present invention as set forth in claim 1, by shifting the flange surface in the vehicle width direction Since two or more surfaces are formed, two or more surfaces of the front pillar reinforce and the rock reinforce are formed at positions separated from each other in the vehicle width direction. Therefore, the coupling rigidity between the front pillar reinforce and the rock reinforce can be improved.
