DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a packing box connected to a rear side of a front body of a so-called panel van type vehicle with a front body.

[0002]

2. Description of the Related Art A front body and a packing box of a panel van type vehicle are separately manufactured and then connected together. An example of a connection structure between the front body and the packing box will be described with reference to FIGS.

FIG. 5 is a side view of the front body 11 and the packing box 12 connected to each other. A substantially rectangular front end 12 'on the front of the packing box 12 is provided with a sealing rubber 13 as shown in the sectional view of FIG.
In a state where they are abutted against each other at the peripheral portions thereof, a plurality of peripheral portions of the both portions are connected by a connecting bracket 14 disposed at a predetermined interval. A continuous U-shaped gate-shaped rainwater discharge rain guide 17 and a rain guide 17 are provided on both sides (a portion in FIG. 6) and an upper side of the rear surface of the front body 11.
A plurality of L-shaped mounting brackets 18 are protruded at predetermined intervals near the inside of the bracket. The packing box 12 has a rectangular parallelepiped shape mainly composed of a panel material. A reinforcing panel 20 having, for example, a pillar structure is fixed to an inner surface of an outer plate 19 at a front end portion 12 ′, and a gate-shaped sealing panel is provided forward from the reinforcing panel 20. 21 extends. The seal panel 21 is a gate-shaped panel that is continuous with both sides and the upper side of the front end 12 ′ of the packing box 12, and one seal rubber 13 is fitted to the front end thereof.

[0004] As shown in FIG. 7, a front body 11 and a packing box 12 are separately manufactured, painted by an electrodeposition method or the like, and then connected. The seal rubber 13 is fitted to the seal panel 21 of the painted packing box 12, and the packing box 12 is abutted against the painted front body 11. With the seal rubber 13 pressed and compressed by the front body 11 and the packing box 12,
By fastening both ends of the connection bracket 14 as shown in FIG. 8 to the mounting bracket 18 of the front body 11 and the reinforcing panel 20 of the packing box 12 with bolts 15, 15, the front body 11 and the packing box 12 are connected and integrated. You. A plurality of connection brackets 14 are used, and the mounting bracket 18 of the front body 11 to which the connection bracket 14 is bolted and the packing box 1 are used.
The nut 1 is previously set at the bolting point of the reinforcing panel 20
6 and 16 are fixed by welding, and bolts 15 and 15 are screwed to the nuts 16 and 16, respectively.

[0005]

The front body 11 and the packing box 12 are connected to a plurality of connecting brackets 14 by bolts. However, such a packing box mounting structure causes the front body 11 and the packing box to be connected to each other by loosening of bolts or the like. The connection strength of the box 12 may become unstable. Further, when the number of the connection brackets 14 is increased, the connection strength between the front body 11 and the packing box 12 is increased, but there is a problem that the number of connection work steps such as bolting is increased.

The connected front body 11 and packing box 12
The seal rubber 13 prevents rainwater that has passed through the rain guide 17 from entering the packing box 12. However, in order to secure the sealing property of the sealing rubber 13, the front body 11 and the packing box 12 are painted. And then seal rubber 13 into packing box 1
2, the front body 11 and the packing box 12 must be connected to each other.

That is, the coating process of the front body 11 and the packing box 12 includes a baking process of dipping in an electrodeposition solution in an electrodeposition tank and baking at a high temperature (about 200 ° C.) in a baking furnace. If the front body 11 and the packing box 12 are connected to each other with the sealing rubber 13 interposed therebetween before the coating process, the sealing rubber 13 is deteriorated by the heat of the baking process to deteriorate the sealing property.
It is also possible to increase the heat resistance by increasing the silicon content of the seal rubber 13 made of silicone rubber so that the seal rubber 13 is not deteriorated by the heat of the paint baking process. There is a problem that the silicon of the seal rubber is melted by the electrodeposition liquid. Furthermore, the front body 11
When the paint is applied after connecting the
The paint adheres to the seal rubber 13 and the adhered paint may deteriorate the elasticity of the seal rubber 13 to lower the sealing performance.

From the above, after the front body 11 and the packing box 12 are individually coated, the two are connected in the above-described manner. However, it has been difficult to reduce the manufacturing cost of a panel van type car because of the complicated equipment and the long time required for painting. In addition, when the painted packing box 12 is connected to the painted front body 11 by a crane or the like, the front packing 11 and the packing box 12 are not connected.
Painted surface may be damaged by contact with a crane or the like.

Further, the seal rubber 13 is pressed into the rear side of the front body 11 inwardly of the rain guide 17,
The seal rubber 13 alone prevents rainwater that has passed through the rain guide 17 from entering between the front body 11 and the packing box 12. Rainwater may enter, and there is a problem in sealing performance against rainwater.

When the front body 11 and the packing box 12 are connected to each other, a gap g 'is formed between them so as to compress the seal rubber 13 appropriately.
Is difficult to make smaller. That is, if the gap g 'is set to be small, when the front body 11 and the packing box 12 are connected to each other, they may abut and the sealing rubber 13 is not sufficiently compressed, so that the sealing performance may be deteriorated. Therefore, the gap g 'is set to be somewhat large. However, in this case, the gap g' is conspicuous at the connection boundary portion between the front body 11 and the packing box 12, which is not preferable in the appearance of the vehicle.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cargo box mounting structure for a panel van type vehicle in which the connection strength between the front body and the cargo box, the connection workability, and the sealability are improved.

[0012]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a gate-shaped first mounting reinforcing plate continuously projecting from both sides and an upper side of a substantially rectangular rear surface of a front body. A gate-shaped second mounting reinforcing plate continuously formed on both sides of the substantially rectangular front end surface of the packing box and an inner surface of the upper side thereof on the outer surface side, and a gate-shaped sealing material is provided between the mounting reinforcing plates. The packing box is integrally connected to the rear side of the front body by fitting and connecting and integrating with the intervening state.

Here, the first mounting reinforcing plate of the front body and the second mounting reinforcing plate of the packing box are connected to each other by bolts or the like to function as a connecting plate for connecting the front body and the packing box. It also functions as a reinforcing plate to reinforce the peripheral edge of the front end of the box, and stabilizes the connection strength between the front body and the packing box. In addition, the sealing material interposed between the two mounting reinforcing plates is sandwiched and pressed by the two mounting reinforcing plates and elastically contacts the two mounting reinforcing plates. A foam sealing material such as seal urethane which is pressed against the plate is used.

Further, the present invention is characterized in that the sealing material interposed between the two mounting reinforcing plates is a sealing material that expands and expands when heated. The foam sealing material in this case is
Seal urethane, etc., which expands and expands due to the heat of the painting and baking process of the front body and the packing box, is used.By using this foam sealing material, after connecting the packing box to the unpainted front body, the front body and the packing box It becomes possible to simultaneously paint an integral object.

Further, the present invention is characterized in that a rain guide for regulating the flowing direction of rainwater is formed on the outer surface side of the first mounting reinforcing plate of the front body, and a sealing material is arranged along the rain guide.

By disposing a sealing material inside the rain guide formed on the outer surface side of the first mounting reinforcing plate of the front body, the sealing material seals rainwater that has entered the rain guide, and the rainwater temporarily passes through the sealing material. Even then, the rainwater is discharged out of the packing box along the rain guide, and as a result, the rainwater is sealed in two stages by the sealing material and the rain guide.

Further, the present invention achieves the object of more securely sealing the connection between the front body and the packing box.
The opening end of the second mounting reinforcing plate is made to approach the root of the outer surface of the first mounting reinforcing plate, and a body sealer for sealing the gap is applied to a gap between the two approaching reinforcing plates.

The body sealer prevents rainwater from entering the rain guide of the front body, prevents rain water from entering into the packing box together with the foam sealing material of the rain guide, and also prevents the boundary between the front body and the packing box from flowing. It also has the function of filling gaps and improving the appearance.

And after the connection, the front body 1 and the packing box 2 can be simultaneously painted. Such a connection between the front body 1 and the packing box 2 is shown in FIGS. 2 and 3 and will be described.

As shown in FIGS. 2 and 3, an unfoamed elongated sealing material 5 is placed on the rain guide 6 of the unpainted front body 1. After this, the rear end 1 'of the front body 1
The unpainted cargo box 2 is carried by a crane or the like directly above and
The both sides of the side rear plate portion 4c ₂ of the second mounting reinforcing plate 4 is lowered beneath the Nibako 2 as shown in the front body 1 1
Sliding on the outer surface of the side rear plate portion 3b ₂ of the attachment reinforcing plate 3. With this slide, the packing box 2 is guided by the first mounting reinforcing plate 3 and is accurately lowered in a positioned state. When the packing box 2 is lowered to the predetermined lower limit position, the second mounting reinforcing plate 4
The upper rear plate portion 4b ₁ of the first mounting reinforcing plate 3 is the upper rear plate portion 3.
b ₁ faces joined on. Thereafter, a bolt 8 is screwed into the nut 9 of the second mounting reinforcing plate 4 from the inside of the first mounting reinforcing plate 3, and the rear plate portion 3 b of the first mounting reinforcing plate 3 and the second mounting reinforcing plate 4 are screwed.
A plurality of portions of the rear plate portion 4b are bolted, and the front body 1 and the packing box 2 are connected and integrated.

A first mounting reinforcing plate 3 and a second mounting reinforcing plate 4 for directly connecting the front body 1 and the packing box 2 are continuously extending from upper sides of the front body 1 and the packing box 2 to both side sides. Since the two mounting reinforcing plates 3 and 4 overlap to connect the front body 1 and the entire length of both sides from the upper side to the packing box 2, the connection strength is large and stable. In addition, since the connection strength is improved by the two gate-shaped mounting reinforcing plates 3 and 4, the number of bolts 8 for directly connecting the mounting reinforcing plates 3 and 4 is reduced, and the number of connection work is reduced accordingly. Connection workability is improved. Further, the second mounting reinforcing plate 4
Reinforces the front end 2 ′ of the packing box 2. When the packing box 2 is connected to the front body 1, the first mounting reinforcing plate 3 also reinforces the front end 2 ′ of the packing box 2. It becomes stable in strength. When the packing box 2 is connected to the front body 1 as described above, the sealing material 5 is connected to the rain guide 6 and the second
It is located in the space between the central plate portions 4b of the mounting reinforcing plate 4. In this state, when the integrated body of the front body 1 and the packing box 2 is sent to the painting process and painted, the sealing material 5 is heated by the heat (approximately 200 ° C.) at the time of baking and foamed and expanded.
As shown in (B), the rain guide 6 and the second mounting reinforcing plate 4
And tightly seals between the mounting reinforcing plates 3 and 4.

The sealing property of the connecting portion between the front body 1 and the packing box 2 by the sealing material 5 can be adjusted by the amount of expansion of the sealing material 5. If the amount of the sealing material 5 is set a little larger, a strong sealing property is secured. Is done. In addition, since the sealing material 5 is foamed at the time of painting after the connection between the front body 1 and the packing box 2, the gap g between the connecting portions of the front body 1 and the packing box 2 can be set sufficiently small. That is, even if the tip of the outer plate 10 of the packing box 2 is sufficiently close to the base of the rain guide 6 of the front body 1 to set the gap g small, the sealing material 5
The sealability is not impaired. To the extent that the gap g can be made smaller, the appearance of the connection boundary portion between the front body 1 and the packing box 2 becomes good, and the amount of rainwater that enters through the gap g decreases. Further, the rainwater that has entered the gap g is sealed by the foamed sealing material 5, and even if the rainwater passes through the sealing material 5, the rainwater is discharged downward from the lower end portions of the left and right rain guides 6 along the rising portion of the rain guide 6. . That is, the intrusion of rainwater into the cargo box 2 is prevented by the two-stage configuration of the sealing material 5 and the rain guide 6, and more reliable rainwater intrusion is prevented.

Further, as shown in FIG.
It is also possible to apply a body sealer 7 to seal the gap g. The body sealer 7 may be applied after the front body 1 and the packing box 2 are connected and coated (undercoating), and after this coating, the front body 1 and the packing box 2 may be coated. .

Although it is not always necessary to apply the body sealer 7 to the gap g, the gap g is sealed with the body sealer 7 to prevent rainwater from entering, so that the body sealer 7, the sealing material 5 and the rain guide 6 have a triple structure. It is done reliably. Further, by filling the gap g with the body sealer 7, the boundary portion between the front body 1 and the packing box 2 becomes a continuous surface, and the appearance of the boundary portion is further improved.

The front body and the packing box are directly connected to each other by overlapping each other, so that rainwater and the like are drained between the front body and the packing box along the first mounting reinforcing plate to the lower right and left lower ends of the vehicle, and both are drained. It is possible to improve the drainage property or sealing property between them. In addition, the first and second mounting reinforcing plates provide a large and stable connection strength between the front body and the packing box. Bolts for directly connecting the two mounting reinforcing plates by improving the connection strength by the double-walled mounting reinforcing plates. The number of connecting members can be reduced, and the workability of connecting the front body and the packing box can be easily improved. Also,
Since the two reinforcing plates cooperate to reinforce the front end of the packing box connected to the front body, it is possible to provide a panel van type vehicle having a packing box that is stable in strength.

According to the packing box mounting structure of the second aspect, after connecting the front body and the packing box, the foamable sealing material is heated and foamed, and then the front body and the packing box are sent to a coating step to perform coating. However, since there is no concern that the sealing properties of the sealing material will deteriorate, the unified front body and packing box can be simultaneously coated in the final process after connecting the unpainted front body and packing box. In addition to reducing the possibility of occurrence of scratches, it is possible to reduce the manufacturing cost by reducing the size of the coating equipment and the coating time.

According to the packing box mounting structure of the third aspect, since the sealing material is installed along the rain guide of the front body, rainwater intrusion into the packing box is prevented by the two-stage structure of the sealing material and the rain guide. The sealing performance of the connection between the front body and the packing box is further ensured.

According to the packing box mounting structure of the fourth aspect, the sealing property of the connecting portion between the front body and the packing box becomes more reliable by adding the body sealer, and the body sealer fills the gap between the connecting portion between the front body and the packing box. To improve the appearance of the connecting portion.
