Description

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

This invention relates to an automobile equipped with a resin body that is attached to a vehicle body so as to cover a cargo bed behind a driver's cab.

[Prior Art] Four-wheel drive vehicles for off-road driving are equipped with a resin body in which the cargo bed behind the driver's cab is covered with a resin body so that the cargo bed can be used as a passenger compartment. are often seen. The above-mentioned resin body usually includes a roof panel and both side panels connected to both side edges of the roof panel, and the front edge of the roof panel is bolted to a gate-shaped pillar provided at the rear of the driver's cab. It is attached to the vehicle body by bolting an inward flange formed at the lower end of the side panel to the top rail of the side frame. Further, at the rear of the vehicle, a back door window opening is provided surrounded by the rear edge of each of the panels to ensure rearward visibility for the driver. This back door window opening is closed by fitting a back door window glass attached to a side-opening back door of the loading platform. Furthermore, flanges for attaching weather strips are formed extending from the rear inner surfaces of the roof panel and both side panels. A weather strip is attached to the flange to seal the back door window opening by coming into contact with the back door window glass when the back door is closed. In addition, for safety reasons, in such cars with a resin body, a round pipe-shaped member is usually installed at the rear of the vehicle interior, which is surrounded by the resin body. There is a gate-shaped rear pillar member (roll bar) that has a horizontal part extending in the vehicle width direction in the vicinity and two leg parts that extend downward from both ends of this horizontal part and whose lower ends are bolted to the floor panel of the loading platform. It is provided. In the case of a resin body, the strength and rigidity are lower than that of a steel plate body, so even if the roof of the resin body is damaged in the event of a vehicle overturn, the rear pillar member can support the vehicle body and protect the occupants. This is what we are doing.

[Problem that the idea aims to solve]

By the way, since the resin body does not have very high rigidity as described above, it is likely that the body will creak due to vibrations (impacts) etc. when traveling on an uneven road. Such body squeaks can cause fatigue damage, and the squeaks are annoying to passengers. Therefore, it may be possible to solve the above problem by adding a new reinforcement to the inner surface of the resin body to increase the rigidity. However, the above method of installing a new reinforcement is difficult to adopt due to production costs, and there are many problems such as having to secure a new space for installing the reinforcement and increasing the weight of the vehicle. . If possible, it would be better if there was a way to improve the rigidity without making any changes to the conventional structure by making good use of the existing parts of conventional resin-bodied vehicles. Therefore, a method that can be considered is to utilize the rear pillar member as a reinforcing member for the resin body. That is, the rear pillar member and, for example, the mounting flange of the weather strip located immediately behind the rear pillar member are connected via a connection bracket. Thereby, the resin body can be supported and reinforced by the rear pillar member, and the rigidity of the resin body can be improved. Moreover, since the rear pillar member is originally provided in the resin body, it is possible to construct a reinforcing structure for the resin body without making any changes to the conventional vehicle body structure. In this case, the mounting location of the connecting bracket is a problem, but it is desirable that the connecting bracket is as invisible to the occupants as possible, and if the roof part of the resin body can be directly reinforced, it will further improve safety in the event of a vehicle overturning. This will lead to improvements in Therefore, it is optimal for the connection bracket to be attached to the horizontal portion of the rear pillar member, and to, for example, the above-mentioned attachment flange formed on the roof portion of the resin body. Further, as a method for attaching the connection bracket, screwing is one of the most suitable methods, considering that it is removable and that sufficient attachment strength can be obtained. However, even if the connection bracket is attached using the above-mentioned attachment structure, the following problems are expected to occur. That is, as shown in FIG. 3, a weather strip b is attached to the distal end of the mounting flange a. Therefore, the connecting bracket c
The attachment location of the rear end portion to the attachment flange a is limited to the front portion of the attachment flange a. On the other hand, the mounting flange a and the roof panel e of the resin body are close to each other behind and above the horizontal portion d of the rear pillar member, and there is only a narrow gap between them. Therefore, it becomes extremely difficult to screw the connecting bracket c to the rear or upper surface of the horizontal portion d. Furthermore, as mentioned above, since the connecting bracket c is screwed to the front surface of the mounting flange a, when the front end of the connecting bracket c is screwed to the front surface of the horizontal portion d, When it becomes necessary to construct a connection structure that allows the attachment position of the connection bracket c to be adjusted in the front-rear direction, this cannot be met. This also applies to the case where the connecting bracket c is screwed to the rear surface of the horizontal portion d. From this, the connection bracket c is
It is most convenient to attach it to the lower surface of the horizontal part d. However, when the connecting bracket c is screwed to the lower surface of the horizontal portion d, a convex portion is formed on the lower surface of the horizontal portion d due to the head of the screw, the retainer g for attaching the nut f to the horizontal portion d, etc. I'll come. The formation of a convex portion in the vehicle interior is not desirable from a safety standpoint, and also causes the disadvantage that the head clearance in the horizontal portion d is reduced. Additionally, in order to improve the appearance of the vehicle interior and protect passengers in the event of a secondary collision, rear pillar members are usually covered with pads, but if the above-mentioned protrusions are formed, pads When it is rolled up, an unusual bulge is formed only at the attachment point of the connecting bracket, causing the problem that the bat h cannot be attached in a good-looking manner. The present invention was devised based on the above knowledge, and by effectively utilizing the rear pillar member as a reinforcing member for the resin body, it is possible to create a resin body without making any changes to the conventional structure. It is an object of the present invention to provide an automobile with a resin body that can improve the rigidity of the body and is configured so as not to reduce the head clearance in the horizontal part of the rear pillar member or spoil the appearance. purpose.

[Means to solve the problem]

In order to solve the above problems, the present invention takes the following technical measures. In other words, the vehicle with a resin body according to the present invention includes a resin body that has a roof panel and both side panels, and is attached to the vehicle body so as to cover a cargo bed behind the driver's cab, and a resin body that is surrounded by the resin body. is provided in a vehicle interior, and has a horizontal portion extending in the vehicle width direction near the roof of the resin body, and both leg portions extending downward from both ends of the horizontal portion and having lower ends fixed to appropriate portions of the loading platform; A vehicle with a resin body is provided with a rear pillar member formed by bending a round pipe, and a recess is formed on the lower surface of the horizontal part of the rear pillar member by horizontally recessing a part of the horizontal part. On the other hand, a vertical wall extending from the inner surface of the roof panel of the resin body close to the rear of the horizontal part,
A connecting bracket is fixed at its rear end, and a front end of the connecting bracket is fixed to the horizontal lower surface within the recess.

[Action and effect]

In the present invention, a rear pillar member provided to protect an occupant when a vehicle overturns is connected to a resin body via a connection bracket, and the rear pillar member supports part of the external force acting on the resin body. Therefore, since the rear pillar member can function as a reinforcement member for the resin body and the resin body can be supported and reinforced by the rear pillar member, the rigidity of the resin body can be improved. Furthermore, in the present invention, since the connection bracket is connected to the standing wall formed on the inner surface of the roof panel for the resin body, the roof portion of the resin body can be particularly reinforced. Therefore, safety when the vehicle overturns can be further improved. Further, the rear pillar member is originally provided for safety reasons in a vehicle equipped with a resin body. Therefore, there is no need to newly provide a reinforcing member for the resin body. That is, in the present invention, the reinforcing structure for the resin body can be constructed by conveniently utilizing the existing members of the vehicle equipped with the resin body, without making any changes to the existing structure. Furthermore, due to the circumstances explained in the [Problem to be solved by the invention] section, the connection bracket is fixed to the lower surface of the horizontal part of the rear pillar member, but in the case of the present invention, it is fixed to the lower surface of the horizontal part of the rear pillar member. A recess is provided, and the front end portion of the rear pillar member is fixed to the horizontal lower surface within the recess. Therefore, even when the connecting bracket is fixed by screwing it to a horizontal part, the connecting bracket and the head of the screw can be accommodated in the recess.
It is possible to avoid the formation of a convex portion on the lower surface of the horizontal portion. This prevents problems such as a reduction in head clearance in the horizontal portion or a bulge in the bracket connecting portion that deteriorates the appearance when the pad is attached to the rear pillar member.

[Explanation of Examples]

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. As shown in FIG. 4, the resin body 1 includes a roof panel 2 and both side panels 3, 3 connected to both side edges of the roof panel 2. is installed on. Usually, the resin body 1 is attached to the vehicle body by bolting the front edge of the roof panel 1 to a pillar part 5 provided at the rear of the driver's cab, and by using an inward flange ( (not shown) is bolted to a top rail (not shown) of the side frame portion 4a of the loading platform 4.
Further, a back door window opening 6 is provided at the rear of the resin body 1 and is surrounded by the rear edges of the roof panel 2 and both side panels 3, 3. This back door window opening 6 is closed by fitting a back door window glass 4c attached to a side-opening back door 4b of the loading platform 4. In addition, as shown in FIG. 1, on the rear inner surfaces of the roof panel 2 and both side panels 3, 3, there is a weather strip that corresponds to the shape of the back door opening 6 and is exposed to the inside of the back door window opening when viewed from the rear of the vehicle. A mounting flange 7 is formed to extend. A weather strip 8 for sealing a back door window opening is attached to this mounting flange 7. In addition, in a vehicle equipped with such a resin body, in order to ensure safety in the event of the vehicle falling over, there is usually a structure in the rear part of the vehicle interior surrounded by the resin body 1, as shown in FIG. A rear pillar member 9 is provided which is substantially gate-shaped when viewed from the rear. This rear pillar member 9 is composed of a round pipe-shaped member, and has a horizontal portion 9a extending in the vehicle width direction near the roof of the resin body 1, and is supported and fixed to the cargo platform 4 at both ends of the horizontal portion 9a. The legs 9b are respectively provided. Each of the leg portions 9b has a pair of front and rear support legs 9c, 9c that branch into two branches and extend downward.
A bolt fixing plate 9d is fixed to the lower end of each of the supporting legs 9c. The rear pillar member 9 is attached to the vehicle body by bolting the bolt fixing plate 9d to a floor panel or the like of the loading platform 4. Now, in the present invention, the rear pillar member 9
By utilizing this, a reinforcing structure for increasing the rigidity of the resin body 1 is constructed. That is, the bracket 1 connects the rear pillar member 9 and the resin body 1.
Connect via 0. As a result, the rear pillar member 9, which is originally provided as a member to protect the occupants when the vehicle falls, can be effectively used as a reinforcing member for the resin body 1, and the resin body 1 is supported and reinforced by the rear pillar member 9. , the rigidity of the resin body 1 can be improved. The connection bracket 10 is connected to the lower surface of the horizontal portion 9a of the rear pillar member 9 due to the circumstances already described in the section [Problems to be Solved by the Invention]. On the other hand, for the resin body 1, a connecting bracket 10 is attached to a vertical wall extending from the inner surface of the roof panel immediately behind the horizontal portion 9a.
Concatenate. In the case of this example, the mounting flange 7 formed on the roof part is used for the vertical wall, and the horizontal part 9a and the mounting flange 7 are connected at two or three places via the connecting bracket 10. , connects the rear pillar member 9 and the resin body 1. Further, the connecting bracket 10 is attached to the rear pillar member 9 and the mounting flange 7 by screwing them, respectively. Below, the connection structure and connection bracket 1
0 installation method will be explained. As shown in FIGS. 1 and 2, the horizontal portion 9a
A recess 11 is provided on the lower surface of the bracket connecting portion by recessing the portion horizontally. A nut introduction hole 11b is formed in the horizontal depression 11a of the recess 11. Further, a nut retainer 12 having a nut portion 12a in the center is inserted into the horizontal recessed portion 1 by loading the nut portion 12a into the pipe through the nut introduction hole 11b.
It is fixed to 1a. On the other hand, the connecting bracket 10 is formed by bending a flat plate member into an L-shape. A first screw plate portion 10a extending in the front-rear direction is provided at the front end portion of the plate portion 10a to be screwed to the nut retainer 12.
and a second screw plate portion 10b extending upwardly along the front surface of the mounting flange 7 at the rear end thereof.
are provided for each. A circular threaded hole 10c having a diameter larger than the thread diameter of the bracket set screw 13a is bored in the first screw plate portion 10a. Further, the second screw plate portion 10b is provided with a vertically elongated screw through hole 10d. Furthermore, a nut case 14a is fixed to the second screw plate part 10b at a position corresponding to the screw through hole 10d on the front surface thereof.
A movable nut 14 consisting of a nut body 14b that is slidably held in the vertical direction is attached to the nut case 14a. The connection bracket 10 is attached after the pad 15 is attached to the rear pillar member 9. As shown in FIGS. 1 and 2, the pad 15 can be attached to the rear pillar member 9 by wrapping it around the rear pillar member 9 and then tightening fasteners 15a provided on both side edges thereof. In addition, in the case of this example, at bat 15,
A bracket through hole 15b is provided at a position corresponding to the bracket connecting portion of the horizontal portion 9a. Once the attachment of the bud 15 is completed as described above, turn the bud 15 clockwise in FIG. 1 from the normal attachment state where the bracket through hole 15b faces rearward as shown by the solid line in FIG. 1. The bracket through hole 15b is located at a position that substantially coincides with the circumferential position of the recess 11 as shown by the imaginary line in FIG. As a result, the first screw plate portion 10a of the connection bracket 10 is
It can be inserted into the pad through the bracket through hole 15ba and positioned within the recess 11. Also, at this time, the connecting bracket 10 is placed between the rear pillar member 9 and the mounting flange 7, with the second screw plate portion 10b facing the front surface of the mounting flange 7. After that, the bracket set screw 13b is screwed into the nut body 14b of the movable nut 14 through the screw through hole 7a of the mounting flange 7 and the screw through hole 10d of the second screw stop plate part 10b, and the second screw stop plate is screwed into the nut body 14b of the movable nut 14. The portion 10b is screwed to the mounting flange 7. Furthermore, the bracket through hole 1
5b into the pad, and insert the bracket set screw 13a into the nut part 1 of the nut retainer 12 through the screw through hole 10c of the first screw fixing plate part 10a.
2a, the first screw plate portion 10a is attached to the horizontal portion 9a of the rear pillar member 9.
Screw it on. This completes the attachment of the connection bracket 10 to the rear pillar member 9 and the resin body 1. After this, turn the pad 15 in the opposite direction to the above to return it to the normal attachment state as shown by the solid line in FIG. The bracket through hole 15b is made inconspicuous. In the above configuration, as described above, the resin body 1 can be reinforced with the rear pillar member 9, and the rigidity of the resin body 1 can be improved. Moreover, as a reinforcing material for the resin body 1, the rear pillar member 9, which is originally provided in a vehicle equipped with a resin body, is effectively utilized. Further, in the case of this example, the mounting flange 7 of the weather strip 8 for sealing the back door window opening is effectively utilized on the upright wall provided on the resin body 1 as the mounting seat for the connection bracket 10.
Therefore, there is no need to newly provide not only a reinforcing member but also the above-mentioned standing wall, and a new reinforcing structure for the resin body 1 can be constructed with almost no changes to the existing vehicle body structure. Further, a recess 11 is provided on the lower surface of the bracket connection of the horizontal portion 9a, so that the first screw plate portion 10a of the connection bracket 10 and the head of the bracket set screw 13a can be accommodated in the recess 11. ing. Therefore, a convex portion is not formed on the lower surface of the horizontal portion 9a due to the head of the screw 13a, and thereby, in order to screw the connection bracket 10 to the lower surface of the horizontal portion 9a, the horizontal portion 9a This can prevent problems such as a decrease in the head clearance of the pad 15 or a deterioration in the appearance when the pad 15 is worn. Moreover, in this example, the bracket set screw 1
Since the nut to be screwed into the pipe 3a is disposed within the pipe of the horizontal portion 9a, there is no need to provide a very large recess. Furthermore, since the resin body 1 and the rear pillar member 9 are usually attached to the vehicle body by bolting, their attachment positions cannot be strictly controlled, and it is difficult to strictly control the relative positional relationship between the two. I can't. Therefore, the connection bracket 10 is connected to the resin body and the rear pillar member 9.
When screwing the connecting bracket 10 to It is predicted that a problem may occur in which screws cannot be screwed to both the resin body 1 and the rear pillar member 9. However, in this example, connection bracket 1
Screw through hole 1 of second screw plate part 10b of 0
0d is an elongated hole in the vertical direction, and the nut to which the bracket set screw 13b is screwed is a movable nut 14 whose position can be adjusted in the vertical direction.
The attachment position of the connection bracket 10 to the attachment flange 7 can be adjusted in the vertical direction.
Since the screw through hole 10c of the first screw plate portion 10a of the connection bracket 10 is made larger in diameter than the screw diameter of the bracket set screw 13a,
The attachment position of the connection bracket 10 to the rear pillar member 9 can be adjusted in the vehicle longitudinal direction and vehicle width direction. Therefore, when screwing the connection bracket 10 to the resin body 1 and the rear pillar member 9, it is necessary to check the relative positional relationship between the resin body 1 and the rear pillar member 9 in the vertical direction, the longitudinal direction of the vehicle body, and the vehicle width direction. Since it is possible to absorb variations in the connection bracket 10 with the resin body 1,
and can be screwed to the rear pillar member 9 without any problem. Further, on the mounting flange 7 side, a movable nut 14 is used as the nut screwed into the bracket set screw 13b, and the nut body 14b is held by the nut case 14a. Therefore,
When screwing the connecting bracket 10 and the mounting flange 7 together, there is no need to insert your hand into the narrow space between the horizontal portion 9a and the mounting flange 7 to hold each nut, making the screwing work easier. I can do it. By the way, the scope of the present invention is not limited to the above-described embodiments; for example, a standing wall may be newly formed on the inner surface of the roof panel as a mounting seat for the connection bracket in the resin body. Furthermore, it goes without saying that the method of attaching the connection bracket is not particularly limited to screwing.
