Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle body module assembly structure which is constructed by dividing into an undermodule and an atupa module, and which are assembled to form a vehicle body.

0002

[Prior Art] Conventionally, the floor and body side of a car body, along with the roof, engine compartment, etc., have a framework of various strength members with a closed cross-section structure, and various panel materials are successively joined to this framework to form a white body. This is then sequentially transferred to the painting process and assembly process, and finally various functional parts and interior parts are assembled.

However, in the white body assembly and assembly process, the assembly work is performed sequentially in the above-mentioned manner on each main line, so the main line becomes long and the equipment becomes larger and expanded, resulting in lower costs. It will be disadvantageous. In addition, if the floor and body sides are configured in advance, when assembling various parts inside the floor and inside the body side during the assembly process, it is difficult for workers to enter the cabin or through the openings on the body side. This has to be done manually, which requires a lot of effort and time.

[0004] As a vehicle body structure to improve this, as shown in FIG. 22, the vehicle body is divided into two parts, an undermodule 182 and an atupa module 184, at a rocker portion 180 and a front pillar lower part 181, and these undermodules 1
A so-called car body module assembly structure, in which a car body is constructed by combining the 82 and the Atsupa module 184, is disclosed in Japanese Utility Model Application Laid-Open No. 64-28377. In addition, as shown in FIG. 23, the rocker part 180 is
80A and a rocker upper part 180B.

By the way, as shown in FIG. 23, the vehicle is equipped with a seat belt device 19 that prevents the vehicle from moving forward due to the inertial force applied to the occupant seated in the seat during sudden deceleration.
0 is attached. This seat belt device 190 includes a winding device 194 that winds up a layer of webbing 192 for restraining an occupant, and this winding device 194 is attached to the lower part of the center pillar 186 on the side of the atupa module 184. Further, the webbing 192 pulled out from the take-up device 194 has its middle portion aligned with the center pillar 18.
6 above the vehicle, and is wrapped around a slip joint 196 provided at the top of the center pillar 186. The tip of the webbing 192 is attached to the rocker portion (lower rocker 180A) on the undermodule 182 side via an anchor plate 198.

A tongue plate 200 is inserted through the middle part of the webbing 192.
00 into a buckle (not shown) provided near the center console of the vehicle, the mounting state is achieved.

[0007]

However, in the above conventional structure, the winding device 194 and the slip joint 1
96 is attached to the atupa module 184 side, and the anchor plate 198 is attached to the undermodule 182 side. Therefore, the seat belt device 190 can only be assembled after the atupa module 184 and the undermodule 182 are assembled. . Therefore, there is a problem that there is no freedom in assembly work and work efficiency is poor.

[0008] In order to solve this problem, the seat belt device 1
Although it is conceivable to attach all 90 to the Atsupa module 184 side, the load applied to the anchor plate 198 will be received only at the Atsupa module 184 side, which is not preferable.

In view of the above facts, the present invention has been developed to increase the degree of freedom in the assembly process by attaching the seat belt device only to the atupa module, and to reliably transmit the input load from the seatbelt device applied to the atupa module to the undermodule. The purpose is to obtain a modular assembly structure for the vehicle body that allows for.

0010

[Means for Solving the Problems] A vehicle body module assembly structure according to the present invention includes an undermodule that forms an underbody and is provided with a rocker lower part, and an atsupa module that forms the area around the roof and around the door opening and is provided with a center pillar. and a vehicle body module assembly structure in which the undermodule is recessed at a position corresponding to the center pillar at the bottom of the rocker downwardly of the vehicle, and the lower part of the center pillar is moved toward the lower part of the rocker. An anchor plate for locking the tip of the webbing of the seat belt device is attached to the bulge, and the anchor plate mounting portion and the lower side of the lower part of the locker are connected by reinforcement. .

[0011]

[Operation] According to the present invention, the lower part of the center pillar is bulged toward the lower part of the rocker and is fitted into the recessed lower part of the rocker, so that the anchor plate that locks the tip of the webbing of the seat belt device can be fixed. The mounting position is Atsupa module. In addition, a member (
For example, a slip joint (for example, a slip joint) is usually attached to the top of the center pillar, so the seat belt device is all a component on the top module side.

[0012] Therefore, in the state of Atupa module alone,
The seat belt device can be assembled, and the work after assembling the atupa module and the undermodule can be reduced. That is, the degree of freedom in the work process is increased, and work efficiency can be improved.

Furthermore, since the anchor plate mounting portion and the lower part of the rocker on the undermodule side are connected by reinforcement, the load applied to the anchor plate can be efficiently transmitted to the undermodule side as well.
