Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a connection structure between panels constituting a resin body, particularly between a roof panel and a side panel.

[Conventional technology]

In some off-road vehicles, the luggage compartment behind the roll bar is covered with a resin body made by bonding resin panels instead of a hood, and the interior can be used as a passenger compartment. There is something like this. This resin body usually has a
It is constructed by joining together a separately molded roof panel and both side panels, and is attached to the vehicle body by fixing the front and rear edges to the roll bar and the lower part to the top rail of the loading platform. Cover in a box shape.

[Problem that the invention attempts to solve]

By the way, for example, when connecting the side edge of the roof panel and the side panel, conventionally, the side edge of the roof panel and the upper edge of the side panel are overlapped with each other, and these parts are tightened with bolts at predetermined intervals. It was being done. However, the bolts mentioned above are usually arranged in a line in the front-rear direction, and as a result, the bending rigidity in the vehicle width direction at the joint between the roof panel and the side panel is generally low, and the resin body In addition to lowering the overall rigidity, there was a problem in that it required careful handling before being installed on the vehicle body. This idea was devised under the above circumstances, and aims to improve the rigidity of the joint between the roof panel and side panel in a resin body, especially in the vehicle width direction, with a simple configuration. With the goal.

[Means to solve the problem]

In order to solve the above problem, this invention takes the following technical measures. That is, it includes a roof panel and both side panels whose upper edges are connected to both side edges of the roof panel, the front edges of the roof panel and both side panels are fixed to a roll bar, and the lower edges of both side panels are fixed to a roll bar. In the resin body that is fixed to the top rail of the side frame of the cargo platform, the connecting portion between the side edge of the roof panel and the upper edge of the side panel is provided with an overlapping portion where both panels overlap each other, and this overlapping portion is It is connected by a plurality of bolts arranged in parallel in the direction and nuts fastened to the bolts, and both panels at both ends or one end of the overlapping part in the vehicle width direction with respect to the row of bolts are connected. Vertical ribs are provided that overlap each other in the front-rear direction at positions offset from each other and extend in the vehicle width direction, and the overlapping portions of the vertical ribs are connected by bolts inserted in the front-rear direction and nuts screwed into the bolts. are doing.

[Action and effect]

In the present invention, the roof panel and the side panel are basically connected by overlapping their edges and fastening this overlapping portion with bolts and nuts. In addition to this, both panels are provided with vertical ribs that overlap back and forth at positions offset in the vehicle width direction with respect to the row of bolts and nuts at the ends of the overlapping parts, and these vertical ribs overlap. The parts are connected by bolts and nuts fastened to the bolts. That is, in the present invention, at the end of the joint between the edges of the roof panel and the side panel, there are bolts and nuts that fasten the overlapping parts of the panels themselves, and vertical ribs that are offset in the vehicle width direction with respect to the bolts and nuts. It has two fastening parts that are separated in the vehicle width direction from the bolts and nuts that fasten the roof panel to the side panel. will increase. Moreover, since vertical ribs extending in the vehicle width direction are formed on the inner surfaces of both panels, these vertical ribs also increase the bending rigidity of the roof panel and side panels themselves in the vehicle width direction. Coupled with the improvement in the bending rigidity of the parts, this has the effect of dramatically increasing the rigidity of the entire resin body, which also significantly reduces the vibration and noise of the resin body. Before being attached to the vehicle body, the resin body is often handled by gripping or supporting both front and rear ends of the side panels, and the bending moment caused by this is applied to the front and rear ends of the joint between both panels. There is a concern that the strength of this part may be insufficient, but if the roof panel and side panel are connected first as described above, the end of the connecting part of both panels will have sufficient strength against bending. The above concerns will be resolved.

[Explanation of Examples]

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 4 shows a vehicle body 2 to which a resin body 1 according to the present invention is attached. The vehicle body has a roll bar 3 and a luggage compartment behind the roll bar 3, and the luggage compartment is surrounded by both side frames 4 rising from both side edges of the roll bar 3 and a side-opening door type tailgate 5. The resin body 1 includes a roof panel 6 and both side panels 7, and is configured by connecting both side edges of the roof panel 6 and the upper edges of both side panels 7. The front edges of the side panels 7 are fixed to the roll bar 3, and the lower portions of both side panels 7 are fixed to the top rails (not shown) of the side frames 4, so that they are attached to the vehicle body. Window openings of a predetermined shape are formed in both side panels 7, and window glasses 8 are attached to these openings, and
A back window opening surrounded by the rear ends of the roof panel 6 and side panels 7 and the upper edge of the tailgate 5 is closed by a back window glass 9 attached to the tailgate 5. The side edge of the roof panel 6 and the side panel 7
Details of the upper edge connecting portion are shown in FIGS. 1 to 3. In addition, the figure shows the parts indicated by reference numeral 1 in FIG. 4, that is, both panels 6 on the left side of the vehicle,
7, that is, the roll bar 3
It shows the structure of the end of the edge. As shown in FIG. 1, on the upper surface of the side edge of the roof panel 6, except for a predetermined length of the front end, there is a roof panel-side first connecting portion 10 which is thinned on the step. A plurality of bolt holes 11 are formed in this connecting portion 10 at predetermined intervals. In addition, in this example,
A band-shaped packing rubber 13 that is pressed from above by the inner surface of the side panel 7 to perform a sealing action is inserted into the groove 12 provided in the region extending from the stepped portion to the connecting portion 10. There is. An extension part 14 extending outward in the vehicle width direction is integrally formed at the front end of the side edge of the roof panel 6, and an extension part 14 extending in the vehicle width direction is formed on the inner surface of the front edge of the roof panel 6. The vertical rib 15 thus formed is bent in a crank shape along the extension 14 to form a roof panel side second connecting portion 16 rising along the rear edge of the extension 13 and on its inner surface. This connecting portion 16 is formed with a bolt through hole 17 in the front-rear direction. Since the extension portion 14 extends in the vehicle width direction from the side edge of the roof panel 6, this bolt through hole 17 is similar to the bolt through hole 11 made in the first connecting portion 10.
This means that the vehicle is deviated a predetermined distance outward in the vehicle width direction. On the other hand, when the upper edge of the side panel 7 is stacked on the first connecting portion 10, the outer surface becomes the roof panel 6.
a side panel side first connecting portion 19 which is formed flush with the bolt hole 11 and has a predetermined nut plate 18 held on the inner surface corresponding to the bolt through hole 11;
is formed, and on the inner surface of its leading edge,
A vertical rib 20 in the vehicle width direction is formed. The position of the inner end of the vertical rib 20 in the longitudinal direction of the vehicle is determined so that it overlaps the rear surface of the vertical rib-shaped roof panel side second connecting portion 16, and this portion connects the side panel side second connecting portion 21. A bolt through hole 22 corresponding to the bolt through hole 16 is provided. Note that the nut plate 18 is
As shown in FIGS. 1 and 2, the plate 8a is a rectangular plate that supports a grooved guide 23 formed on the inner surface of the first connecting portion 19 on the side panel side in a substantially horizontal manner in the vehicle width direction. inserted. In addition, a reinforcing rib 24 in the vehicle width direction is provided slightly rearward of the region where the vertical rib 20 is provided, and a notch 25 is provided in a region of this reinforcing rib corresponding to the second connecting portion in the longitudinal direction. A working hole is formed for bolt fastening work, and a cover 26 is inserted into this notch 25 so that the bolt 27 after fastening cannot be easily seen from the passenger compartment. The roof panel 6 and side panel 7 of this example having the first and second attachment portions described above are connected in the following manner. That is, the side panel side first connection part 19 is vertically overlapped with the roof panel side first connection part 10, and at the same time, the roof panel side second connection part 16
and the side panel side second connecting portion 21 are overlapped back and forth. As shown in FIG. 2, the overlapping part A between the first connecting parts 10 and 19 connects the bolt 27 passed through the bolt through hole 11 of the first connecting part 10 on the roof panel side to the first connecting part 10 on the side panel side. The portion 19 is connected and fixed by being screwed into the nut 18a of the nut plate 18 on the back side, and the overlapping portion B between the second connecting portions 16 and 21 is formed by attaching the cover 26 as shown in FIG. Removed notch 25
They are connected by connecting a nut 28 to a bolt 29 which is inserted into the bolt through hole 17, 22 of each second connecting part 16, 21 so as to be a working hole. After fastening the bolts 29, the cover 26 is inserted into the notch 25. In addition, when stacking the side panel 7 on the roof panel 6, the above-mentioned gasket 13 is fitted into the groove 12, and also between the extension part 14 on the roof panel side and the side panel 7 overlapping with this. , a seal rubber 30 is sandwiched. In this example, as shown in FIG. 3, the nut 28 is a weld nut disposed inside the roll bar 3, and the bolt 29 is screwed into the weld nut.
On the other hand, it also provides a function of connecting the second connecting parts 16 and 21 and a function of fixing the connected body of the second connecting parts 16 and 21 to the roll bar 3. The above explanation is based on the drawing showing the connection between the left edge of the roof panel 6 and the left side panel 7, but the connection between the right edge of the roof panel 6 and the right side panel is as described above. Needless to say, it is the same. As mentioned above, in the connection structure between the roof panel 6 and the side panel 7 of the resin body of this example, the first connection part and the second connection part of each panel are offset in the vehicle width direction. The bending rigidity in the vehicle width direction at the ends of the connection structure is improved. Since each second connecting portion is constructed by overlapping vertical ribs in the vehicle width direction, the section modulus increases by itself, thereby increasing the bending rigidity of each panel. This, combined with the fact that the first and second connecting portions are offset from each other in the vehicle width direction, dramatically improves the rigidity of the resin body as a whole. Furthermore, since the second connecting portion is deviated outward in the vehicle width direction, the amount of extension in the vehicle width direction of the vertical ribs 20 and reinforcing ribs 24 to be provided on the side panel 7 is reduced, and these ribs are shaped. Even if a drafting slope is provided, sufficient strength can be provided to these ribs. That is, in this example, the side panel has a shape in which the upper part thereof is largely curved inward, but the die cutting direction is in the vehicle width direction, so there is a concern about the strength of the rib after forming the die cutting slope. However, if the present invention is applied, this concern will disappear. Of course, the scope of this invention is not limited to the above-described embodiments. The embodiment is an example in which the present invention is applied to the front end of the joint between the roof panel and the side panel, that is, the area adjacent to the roll bar, but it is possible to apply the present invention to the rear end of the joint. Not even. In addition, in the embodiment, the upper edge of the side panel is overlapped on the side edge of the roof panel, but conversely, the side edge of the roof panel is overlapped on the upper edge of the side panel. The present invention can also be applied in the same way.
