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 in which an undermodule and an atupa module are divided and 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 longer and the equipment becomes larger and larger, resulting in lower costs. be disadvantageous to 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.

As a vehicle body structure to improve this, as shown in FIG. 7, 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 18
A so-called vehicle body module assembly structure in which a vehicle body is constructed by combining the Atsupa module 184 and the Atsupa module 184 is disclosed in Japanese Unexamined Utility Model Publication No. 64-28377. In addition, Figure 8
As shown in FIG.
A and a rocker upper part 180B.

By the way, as shown in FIG. 8, the vehicle is equipped with a seat belt device 190 that prevents the vehicle from moving forward due to the inertia force applied to the occupant seated in the seat during sudden deceleration.
is installed. This seat belt device 190 is
A winding device 194 is provided for winding up the webbing 192 for restraining an occupant in a layered manner, 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 186.
It is disposed above the vehicle along the center pillar 186 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 attachment 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. . For this reason, there is a problem that there is no freedom in the assembly process and work efficiency is poor.

[0008] In order to solve this problem, the seat belt device 1
Although it is conceivable to attach all of 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. In order for the undermodule 182 to also receive this load, the atsupamodule 184 and the undermodule 1 must be
It is necessary to provide a large distance between the connection points with 82. Therefore, the center pillar protrudes toward the interior of the vehicle, narrowing the interior space.

In consideration of the above-mentioned facts, the present invention increases the degree of freedom in the assembly process by attaching the seat belt device only to the Atsupa module, and reduces the input load from the seat belt device that is applied to the Atsupa module without narrowing the vehicle interior space. The purpose is to obtain a vehicle body module assembly structure that can reliably transmit the information to the undermodule.

A module assembly structure for a vehicle body, in which a lower part of the undermodule corresponding to the center pillar of the lower part of the undermodule is recessed downwardly of the vehicle, and a lower part of the center pillar is fixed to the lower part of the rocker. An anchor plate for locking the tip of the webbing of the seat belt device is attached to this bulging portion, and the bulging portion is made to protrude further into the vehicle interior than the inner wall of the center pillar. It is a feature.

[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 that supports the middle part of the webbing (
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.

[0013] Furthermore, by making the bulge protrude more toward the inside of the vehicle than the inner wall of the center pillar, the mating surfaces of the atupa module and undermodule in the vehicle width direction are enlarged, and the joining points of both ends in the vehicle width direction are separated. be able to. Therefore, the atupa module and the undermodule can be firmly connected, and the load applied from the seat belt device can be reliably transmitted to the undermodule side as well. Furthermore, since only the bulge is protruded, the interior space of the vehicle is not narrowed.

Here, the pitch dimension M of the bolts 85, 112 at the bottom of the center pillar 22 (see FIG. 2) is:
The pitch dimension L of the center pillar 22 other than the lower part is set larger than that of the center pillar 22.

The operation of this embodiment will be explained below. U.P.R.
M12 and UNDRM16 are assembled with parts that can be assembled individually. The UPRM 12 includes a seat belt device 96 as a part that can be assembled.

The procedure for assembling the seat belt device 96 is to first attach the retractor 99 to the lower part of the center pillar 22. Next, the slip joint 100 is installed above the center pillar 22, and the bulge 88 below the center pillar 22 is
Attach the anchor plate 98 to B.

Next, the webbing 104 is pulled out from the winding device 99, placed above the vehicle along the center pillar 22, and wound around the slip joint 100. The wrapped webbing 104 is placed below the vehicle again, and the tip end is locked to the anchor plate 98. Note that the tongue plate 102 is inserted through the middle part of the webbing wrapped around the slip joint 100.

The assembly of the seat belt device 96 is now complete, and the webbing 104 is rewound into the retractor 99 by a mainspring spring (not shown) in the retractor 99.
It is arranged along the center pillar 22 without slack.

[0038] When the assembly of the other parts of UPRM12 and UNDRM16 is completed, the UPRM12 is replaced with UNDRM16.
16, UPRM12 and UNDRM1
Assemble 6. At this time, the lower protruding portion 88B of the center pillar 22 is connected to the recessed portion 9 provided in the lower rocker portion 64.
5 is fitted. Therefore, the rocker upper part 40 and the rocker lower part 64 can be assembled without any gap.

According to this embodiment, the lower part of the center pillar 22 is bulged in the direction of the rocker lower part 64 (bulged portion 41), and the mounting position of the anchor plate 98 is made to correspond to the UPRM 12, so that the seat belt device 96 is UPRM all parts
This seat belt device 96 can be assembled into the UPRM 12 as a single unit.

[0040] For this reason, UPRM12 and UNDRM16
It is possible to reduce the amount of work required after assembly and improve work efficiency.

As shown in FIG. 2, the mating surface of the rocker upper part 40 and the rocker lower part 64 at the lower part of the center pillar 22 protrudes more toward the inside of the vehicle than the center pillar inner 90 (the protruding surface Section 88B). Therefore, the pitch dimension M between the bolt 85 and the bolt 112 can be made larger than the pitch dimension L between the bolt 83 and the bolt 85 shown in FIG. For this reason, the upper part of Rotsuka 40
The rigidity of the connection between the lower part 64 and the rocker lower part 64 is increased. By increasing the joint rigidity, the load applied to the webbing 104 due to the inertial force of the occupant when the vehicle suddenly decelerates is transferred to the anchor plate 98.
The load input to the upper rocker 40 can be efficiently transmitted to the lower rocker 64 through the rocker.

That is, the seat belt device 96 is
Even if the entire rocker is assembled to the RM12, the load applied to the anchor plate 98 when assembled to the UNDRM16 can be received by the entire rocker.

[0043] Further, the bolt 85,
Since the pitch dimension of 112 is large, UPRM
12 and the UNDRM 16, and the protrusion 88B is attached to the rocker lower part 64 of the UNDRM 16.
Since it is only provided in the vehicle, it does not narrow the interior space of the vehicle.

[0044]

[Effects of the Invention] As explained above, the vehicle body module assembly structure according to the present invention allows the seat belt device to be attached only to the Atsupa module, increasing the degree of freedom in the assembly process and eliminating the need to narrow the interior space of the vehicle. This has an excellent effect in that the input load from the seat belt device applied to the atupa module can be reliably transmitted to the undermodule.
