CONSTITUTION:A car body 10 is divided into an upper module 16 for forming the periphery of a roof 12 and the periphery of a door opening 14 and an under module UNDRM 20 for forming an under body, and the dividing positions of the respective modules are closed section portions. A tire house 30 is formed on both sides portions of the rear side of a vehicle of the UNDRM 20, and an upper back panel 34 is stretched between suspension towers 32 formed on the upper end portion of the tire house 30. In this arrangement, projecting portions 42 projected below the vehicle are formed on both end portions in the width direction of the upper back panel 34, and engaged with recess portions 44 formed on the suspension towers 32. After that, both the suspension towers 32 and the upper back panel 34 are removably connected to each other by bolts 50 and nuts 52.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a module assembly structure for an automobile body in which an upper module and an undermodule constituting the automobile body are combined and assembled.

[Prior art]

Conventionally, white car bodies require large production line equipment, and when assembling various parts on the inside of the floor or the inside of the body, workers have to enter the cabin or manually work through the openings on the side of the body. must be done.

In order to solve this problem, a so-called module assembly structure for an automobile body is developed, in which the vehicle body is divided into two parts at a rocker into an upper module and an undermodule, and the upper module and undermodule are connected at the rocker to form the vehicle body. Articles of incorporation (for example, Jikken Hei 2)
No. 49483).

That is, as shown in FIG.
The vehicle body 60 is divided into an upper module 66 that forms the area around the vehicle body 60 and the area around the door opening 164, an under module 68 that forms the underbody, and a front end module 70 that forms the front surface of the vehicle body 60.

A tire house 72 and a suspension tower 74 are also integrally formed on the undermodule 68, and an upper back panel 76 is provided between the pair of suspension towers in the vehicle width direction. Since various parts inside the body are assembled to the undermodule 68 before it is joined to the upper module 66, the working space is expanded.

[Problem to be solved by the invention]

However, although interior components such as speakers and air purifiers are assembled to the upper back panel 76, the space between the floor surface 78 and the upper back panel 76 is narrow, and the work space is significantly narrower than other parts. . As a result, the assembly workability is reduced as a whole.

The present invention has been made in consideration of the above facts, and an object of the present invention is to obtain a module assembly structure for an automobile body that can improve the ease of assembling various parts inside the body as a whole.

[Means to solve the problem]

The module assembly structure for an automobile body according to the present invention is a module assembly for an automobile body in which an upper module and an under module of a vehicle body are assembled, which are separated by rocker parts disposed at both ends in the width direction of the vehicle and extending in the longitudinal direction of the vehicle. The suspension structure is characterized in that an upper back panel connected between a pair of suspension towers in the vehicle width direction in the undermodule is removable.

[Effect]

According to the present invention, the upper back panel is separated from the undermodule and can be detached, so after the parts to be assembled to the upper back panel are assembled as a single upper back panel, the parts are transferred between the suspension towers. be able to. For this reason, a narrow space between the upper back panel and the undermodule floor panel in the assembled state will be described.An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

In the figure, arrow FR indicates the forward direction of the vehicle, arrow IN indicates the inside direction of the vehicle, and arrow UP indicates the upward direction of the vehicle.

As shown in FIG. 1, the vehicle body 10 includes an upper module (hereinafter referred to as UPRM) 16 that constitutes the area around the roof 12 and the area around the door opening 14, an under module (hereinafter referred to as UNDRM) 20 that constitutes the underbody, and the vehicle body 1.
0, and a front end module 21 that constitutes the front side of 0.

Each dividing position of these UPRMI 6 and UNDRM 20 is a closed cross-section portion such as the front pillar lower part 22, rocker 24, cowl 26, etc., and each of these closed space portions is divided into two along the longitudinal direction, and the UPRMI 6 and UNDR
Each end frame member is M20. Therefore, U.P.R.
MI6 and UNDRM20 each have a closed cross section at each end, and UPRMI6 and UNDRM20
The unit rigidity of each is increased.

There are tire houses 3 on both sides of the rear side of the UNDRM20 vehicle.
0 is formed. A suspension tower 32 is formed at the upper end of the tire house 30 to support the upper end of a suspension (not shown). An upper back panel 34 is provided between these suspension towers 32.

As shown in FIG. 3, the upper back panel 34 is connected to a speaker 3 that constitutes a part of the audio equipment that is an interior component.
6 and its wiring 38, and a mat 40 is laid on the upper surface exposed in the vehicle interior. This interior item etc.
The upper back panel 34 is attached as a single unit.

As shown in FIG. 2, at both ends of the upper back panel 340 in the vehicle width direction, a substantially U-shaped convex portion 42 that protrudes downward from the vehicle is formed by press molding. This convex portion 42
Correspondingly, a recess 44 is formed in the suspension tower 32, and the protrusion 42 is accommodated in the recess 44. The convex portion 42 and the concave portion 44 are formed with circular holes 46 and 48 which are coaxial when accommodated, respectively. The upper back panel 34 is fixed to the suspension tower 32 by passing the bolts 50 through the circular holes 46 and 48 and screwing the nuts 52 together.

The operation of this embodiment will be explained below.

77 The back panel 34 has the speaker 3 as a standalone unit.
6 and its wiring 38 are provided, and a mat 40 is laid on the upper surface. This assembly work is performed on the upper back panel 32.
Since it is carried out in a stand-alone state, it can be carried out without any problems.

On the other hand, various parts inside the body are assembled to the respective parts of the UNDRM 20 without the upper back panel 34.

After the various parts mentioned above are assembled, the upper back panel 34 is hung between the suspension towers 32. here,
When the convex part 42 of the upper back panel 34 is accommodated in the concave part 44 of the suspension tower 32, each circular hole 4
6.48 are placed coaxially. Next, this circular hole 46.4
The upper back panel 34 is fixed to the suspension tower 32 by passing the bolt 50 through it and screwing it together with the nut 52.

Similar to the UNDRM20 above, various parts inside the body are assembled into the UPRM16, and in this state, the UND
RM20 and UPRM16 are front pillar lower part 22,
The vehicle body 10 is formed by joining the rocker 24, the cowl 26, and the like.

According to this embodiment, the upper back panel 34 is
Since it is retrofitted to the M20, there is no need to assemble various parts in the narrow space between the upper back panel 34 and the floor surface of the UNDRM20, improving work efficiency. Further, by releasing the screw engagement with the upper back panel 34, the upper back panel 34 can be easily removed, and work efficiency can be improved even when adding assembled parts such as an air cleaner.

In this embodiment, bolts 50 and nuts 52 are used to make the upper back panel 34 removable, but as shown in FIG. An anchor structure may be used in which a synthetic resin bottle 54 is elastically deformed and fitted during assembly, that is, when the bottle 54 is inserted into the circular hole 46,48.

〔Effect of the invention〕

As explained above, the module assembly structure for an automobile body according to the present invention has the excellent effect of improving the workability of assembling various parts inside the body as a whole.
