[Detailed description of the invention]! , Industry 1f7) Application field] Misfire 1! The combination of the upper frame 4 and the al-da module that make up the seat of a high-speed automatic vehicle] Connecting the lug parts, L, the assembly of the automobile seat that can be seen 1. Concerning construction, E Cong - Song C" - Moon Sho J. To"] Traditionally, automobile bodies were popular for their line equipment, and various parts were placed on the inside of the floor and on the inside of the body side. If the work is to be carried out, the workbench must be inserted into the yabin or a part of the body of the vehicle must be removed.

Is this 8'? ? In order to carry out the portrait, divide the corpuscle into two with the mouth and tongue into the upper module and the outer layer, and then create the upper module and the lower module.

There is a problem in that the outer flange between the width f and b swings, making it difficult to install the bolts for connecting the module. In addition, the applicant of t1 has proposed a module assembly structure that solves the above-mentioned problems and improves workability when assembling modules (Utility Application No. 2i9483).

That is, as shown in FIG. 4(A), the rocker 62 of the upper module 60 is formed by joining the rocker outer 64 and the rocker inner 66 with flanges 68 at the upper and lower ends of the vehicle to form a closed cross section, and the rocker of the under module 70 is The rocker outer 74 and the floor panel 76 form a closed cross section of the rocker outer 72, and the facing surfaces of the rocker inner 66 of the upper module 60 and the rocker outer 74 of the under module 70 are used as guide surfaces 78 and 80 to position them.

As a result, when the upper module 60 and the under module 70 are positioned, the rocker outer 74 and the like of the under module 70 are not deformed, and the assembly work efficiency is improved.

[Problem to be solved by the invention]

However, in the above configuration, when forming a closed cross section in each of the rockers 62.72 of the upper module 60 and the under module 70, dimensional accuracy is required to ensure the exact position of the guide surface 78.80. For this reason, the assembly workability is improved in positioning the upper module 60 and the under module 70, but each member constituting the upper module 60 and the under module 70 requires high dimensional accuracy, which reduces workability. not good.

If there is an error in the dimensional accuracy of each member, as shown in Figure 4 (B), it may become difficult to position the member in a predetermined position.
Alternatively, problems such as distortion in the closed cross section may occur.

In consideration of the above facts, the present invention aims to provide a module assembly structure for an automobile body that can reduce the dimensional accuracy of each member of the module and improve workability during module assembly.

[Means to solve the problem]

The module assembly structure for an automobile body according to the present invention forms a closed cross section by coupling an upper outer member and an upper inner member to a rocker portion of an upper module,
A closed cross section is formed by joining the under side outer member and the under side inner member to the rocker portion of the under module, and by positioning these closed cross sections at predetermined positions, the upper module and the under module are assembled. A module assembly structure for an automobile body, wherein either a part of the joint end between the upper outer member and the upper inner member or a part of the joint end between the lower outer member and the lower inner member It is characterized in that the coupling is performed after determining the position at the predetermined position.

[Effect]

According to the present invention, the outer member and the inner member on the upper side or the under side that constitute the rocker portion of the upper module or the under module are in a state in which at least a part of their connecting ends (for example, the lower side connecting end of the vehicle) are not connected. Position the double-opened sections at predetermined positions, and assemble the upper module and the under module.

At this time, if the dimensional accuracy of each member is slightly different, this dimensional difference generates an unreasonable force that deforms the closed cross sections of both the upper module and the below module. However, in the present invention, this dimensional difference can be absorbed by relative movement between the outer member and the inner member on either the upper side or the under side of the uncoupled end.

After the upper module and the under module are assembled, the unjoined ends of the outer member and the inner member on either the upper side or the under side are connected.

Thereby, there is no problem such as deformation of the closed cross section due to dimensional differences, and the dimensional accuracy of each member can be reduced.

The male screws J and L2A of the bolt 52 inserted into the through hole 42 of the flange 28A of the Mtl lug 2) (t,,%゛・th!-...) are screwed together, so that A flange 28A of the UPM rocker 28 is joined to a base 44E of the UNDRM rocker outer 44.

An outer portion of the floor panel 46 in the vehicle width direction is arranged below the UNDR, M rocker outer 44 in the vehicle vertical direction. Flange 44D of UNDRM rocker outer 44
is welded to the outer side of the floor panel 46 in the vehicle width direction from above in the vehicle vertical direction.

An outer portion in the vehicle width direction of a welded portion 46A of the floor panel 46 to the flange 44D of the UNDRM rocker outer 44 projects downward in the vehicle vertical direction, and forms a stepped portion 46B. The outer end of the stepped portion 46B in the vehicle width direction is bent downward to form a flange 46C.
6C is welded to the flange 44B of the UNDRM rocker outer 44 from the inside in the vehicle width direction, and serves as the flange 30A of the UNDRM rocker 30. Therefore, the UNDRM rocker 30 includes the UNDRM rocker outer 44 and the floor panel 46.
and constitute a closed cross-section portion 54.

In addition, the flange 30A of the UNDRM rocker 30 is UPM
It is preferable that it protrudes slightly downward from the flange 28B of the rocker 28, so that no upward force is applied to the vehicle upon jacking up the UPM rocker 28.

The above UPRM locker 28 and UNDRM locker 30 are:
Surface 5 of UPRM rocker inner 38 facing inside the vehicle
6 and the outer leg portion 4 in the vehicle width direction of the UNDRM rocker outer 44
A surface 58 facing the outside of the vehicle of 4A is opposed.

At the time of assembly, the surfaces 56 and 58 come into surface contact, so that the UPRM rocker 28 is guided and moved in the direction of the arrow in FIG. ing. At this time, since the flange 36E and the lower end 38B of the flange 28B are not welded, even if a force that deforms the shape of the closed cross section 40.54 is generated due to a dimensional error, the relative relationship between the flange 36E and the lower end 38B is It absorbs this force by moving.

Next, the operation of this embodiment will be explained.

UPRM rocker outer 36 to UPRM rocker inner 38
When joining UNDR, as shown in Figure 2, UNDR
A UPRM rocker inner 380 is attached to a surface 58 of the outer leg portion 44A in the vehicle width direction of the M rocker outer 44 facing toward the outside of the vehicle.
Slide the UPRM rocker 28 downward (in the direction of arrow A in FIG. 2) along the surface 56 facing inside the vehicle.

During this sliding, the LJPR that constitutes the UPRM rocker 28
If there is a dimensional error in each member such as the M rocker outer 36 and the UPRM rocker inner 38 or the UNDRM rocker outer 44 constituting the UNDRM rocker 30, a force is generated that deforms the shape of the closed cross section 40.54.

However, in this embodiment, since the flange 36E and the lower end portion 38B are not welded at this point, the flange 36E and the lower end portion 38B are not welded.
The above force can be absorbed by the relative movement between E and the lower end portion 38B.

In other words, even if the dimensional accuracy of each individual member is rough, this dimensional error is absorbed during assembly, and the U P R, M rocker 2
8 and the UNDRM rocker 30 can be reliably positioned at a predetermined position without deforming them.

When the positioning to the predetermined position is completed, the flange 36 is then
E and the lower end 38B are welded (spot welded), and then bolts 52 are inserted into the through holes 42 and 48 and screwed into the weld nuts 50. The through holes 42 and 48 prevent the TJPRM rocker 28 and the UNDRM rocker 30 from deforming as described above, so that the axes will not shift.

Therefore, the through hole 42 of the UPRM rocker outer 36 and the U
Positioning with the through hole 48 of the NDR, M rocker outer 44 can be easily performed, and workability during module connection can be improved.

Finally, the flange 28B of the UPRM rocker 28 and the UND
