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.

[Conventional technology]

Many four-wheel drive vehicles for off-road driving have a resin body that covers the cargo bed behind the driver's cab so that the cargo bed can be used as a passenger compartment. 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, in such cars with a resin body, for safety reasons, there is usually a horizontal part extending in the vehicle width direction near the roof and a horizontal part at both ends of this horizontal part in the cabin surrounded by the resin body. A gate-shaped rear pillar member (roll bar) is provided that extends downward from the rear pillar member and has both leg portions whose lower end portions are bolted and fixed to a floor panel of the cargo platform or the like. In the case of a resin body, the strength and rigidity are lower than that of a steel plate body. Therefore, even if the roof of the resin body is damaged when the vehicle overturns, the rear pillar member can support the vehicle body and protect the occupants.

[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. The present invention was devised under the above circumstances, and provides an automobile with a resin body that can improve the rigidity of the resin body without making any changes to the conventional structure. Its purpose is to.

[Means to solve the problem]

In order to solve the above problems, the present invention takes the following technical measures. That is, the automobile with a resin body set forth in claim 1 of the present application has a roof panel, both side panels, and a back door opening formed surrounded by the rear edge of each of the panels, and has a cargo platform behind the driver's cabin. A resin body that is attached to the vehicle body so as to cover the vehicle; a horizontal portion that is provided in the vehicle interior surrounded by the resin body and extends in the vehicle width direction near the roof of the resin body; A vehicle with a resin body is provided with a rear pillar member having a substantially gate shape in rear view and having both legs extending downward from both ends and having a lower end fixed to a suitable portion of the cargo platform, the rear pillar member is attached to the roof panel and both legs. Extending from the rear inner surface of the side panel,
It is characterized in that it is connected to the mounting flange of the weather strip for the back door opening seal via a connecting bracket. Further, the automobile with a resin body according to claim 2 of the present application is the automobile with a resin body according to claim 1, wherein the first screw fastening portion is provided at the front edge of the connection bracket and the first screw is provided at the rear end. a second screw stopper is provided, and the first screw stopper is screwed to the rear pillar member, and the second screw stopper is screwed to the mounting flange, thereby connecting the rear pillar member and the mounting flange; Each of the screw through holes of the first screw stopper and the second screw stopper is formed to have a larger diameter than the screw diameter.

[Action and effect]

In this invention, the rear pillar reinforcement member, which is provided as a member for protecting the occupants in the event of a vehicle rollover, is connected to the plastic body via a connecting bracket, and the rear pillar reinforcement member supports part of the external force acting on the plastic body. Therefore, the rear pillar reinforcement member functions as a reinforcing member for the plastic body, and the plastic body can be supported and reinforced by the rear pillar reinforcement member.
The rigidity of the plastic body can be improved.
In particular, since the connecting bracket is connected to the mounting flange of the weather strip for sealing the back door opening of the plastic body, it is possible to greatly improve the rigidity of the area around the back door opening, which tends to lose rigidity. Moreover, the rear pillar reinforcement is originally provided as a safety measure in vehicles with plastic bodies, and since the weather strip mounting flange is effectively used as a mounting seat for the connecting bracket on the plastic body side, there is no need to provide a new mounting seat for the connecting bracket on the plastic body. In other words, in this device,
By conveniently utilizing existing parts of a vehicle with a plastic body, a reinforcing structure for the plastic body can be constructed with almost no changes to the previous structure. Also, since the plastic body and the rear pillar bar are usually attached to the vehicle body by bolts, their attachment positions cannot be strictly controlled. In other words, the relative positional relationship between the plastic body and the rear pillar bar is not strictly determined. For this reason, for example, when a connecting bracket is attached to the plastic body and the rear pillar bar by screwing, it is expected that a problem will occur in which the connecting bracket cannot be screwed to both of them because of variations in the relative positional relationship between the screw fastening parts of the plastic body and the screw fastening parts of the rear pillar bar in the vertical direction, the front-rear direction of the vehicle body, and the vehicle width direction. In other words, the screw through hole of the connecting bracket that has been screwed to either the plastic body or the rear pillar bar beforehand does not match the position of the screw fastening part of the other. Therefore, in the device described in claim 2 of the present application,
The screw through holes of the first screw fastening portion of the connecting bracket for screwing to the rear pillar member and the second screw fastening portion for screwing to the plastic body are made larger in diameter than the screw diameter. This allows the mounting position of the connecting bracket to the plastic body and the rear pillar member to be adjusted within a range in which the screws screwed into the plastic body and the rear pillar member can be moved relatively within the screw through holes. Therefore, since the variation in the positional relationship can be absorbed when mounting the connecting bracket, the connecting bracket can be screwed to both the plastic body and the rear pillar member without any problems. In this case, for example, if the screw through holes of the first screw fastening portion are formed as elongated holes in the vehicle width direction and the front-rear direction, and the screw through holes of the second screw fastening portion are formed as elongated holes in the up-down direction, the variation in the positional relationship in the above three directions can be absorbed without any problems.

As shown in FIG. 3, 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 behind 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, a structure such as that 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 has a horizontal portion 9a extending in the vehicle width direction near the roof of the resin body 1.
Leg portions 9b that are supported and fixed to the loading platform 4 are provided at both ends of the loading platform 4, respectively. Each leg 9b has a pair of front and rear supporting legs 9 that branch into two branches and extend downward.
A bolt fixing plate 9d is fixed to the lower end of each supporting leg 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 rear pillar member 9 and the mounting flange 7 of the resin body 1 are connected via the connection bracket 10. As a result, the rear pillar member 9, which is originally provided as a member to protect the occupants when the vehicle overturns,
It can also be effectively used as a reinforcing member for the resin body 1, and the rigidity of the resin body 1 can be improved by supporting and reinforcing the resin body 1 with the rear pillar member 9. In this example, the resin body 1 and the rear pillar member 9 are connected by connecting the mounting flange 7 formed on the roof of the resin body 1 and the horizontal portion 9a of the rear pillar member 9 to the connection bracket 10.
This is done by connecting them at two or three places via , and the connection structure will be explained below. As shown in FIGS. 1 and 2, the horizontal portion 9a
A screw relief hole 9a is provided in the lower surface of the bracket connecting portion, and a pedestal plate 12 integrally having a nut body 11 is fixed so as to cover the screw relief hole 9a. .
This pedestal plate 12 is located horizontally below the horizontal portion 9a, and includes a bracket fixing plate 12a having a screw hole 12c formed in the center thereof, and a pair of front and rear brackets extending upward from the front and rear ends of the bracket fixing plate 12a, respectively. Mounting plate part 12
b, 12b. The nut body 11 is fixed to the upper surface of the bracket stopper plate portion 12a so as to be connected to the screw through hole 12c, and the respective mounting plate portions 12b, 1
2b is welded to the horizontal portion 9a. Further, the connecting bracket 10 has, at the front end,
A first screw fixing plate part 13 extending in the front-rear direction and screwed to the bracket fixing plate part 12a of the pedestal plate 12 is connected to a second screw plate part 13 extending in the vertical direction along the front side surface of the mounting flange 7 at the rear end. Each has a stop plate portion 14. The first screw plate portion 13 is provided with a circular screw through hole 13a having a larger diameter than the bracket screw 16. On the other hand, the second screw plate portion 14 has
A vertically elongated screw through hole 14a is opened. In addition, the screw through hole 14a is provided on the front surface of the screw hole 14a.
A movable nut 15 consisting of a nut case 15a fixed to the second screw plate part 14 at a position corresponding to the nut case 15a, and a nut body 15b held vertically slidably by the nut case 15a.
is installed. Then, as shown in FIG. 1, the first screw plate portion 13 of the connection bracket 10 is attached to the bracket fixing plate 12a of the pedestal plate 12.
The resin body 1 and the rear pillar member 9 are connected by screwing the second screw plate portions 14 to the mounting flanges 7, respectively.
In this case, the first screw fixing plate part 13 is screwed to the bracket fixing plate 12a by screwing the bracket fixing plate 12a to the nut 11 through the screw through hole 13a of the first screw fixing plate part 13. conduct. Further, to screw the second screw plate part 14 to the mounting flange 7, insert the bracket set screw 16 into the screw through hole 7a of the mounting flange 7 and the screw through hole 14a of the second screw plate part 14, Then, it is screwed onto the nut body 15b of the movable nut 15. 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. In addition, the rear pillar member 9, which is originally provided in a vehicle equipped with a resin body, is used as a reinforcing material for the resin body 1, and is used as a mounting seat for the connecting bracket 10 on the resin body side, as a weather strip for sealing the back door window opening. Since the mounting flanges 7 of 8 are effectively utilized, there are almost no changes to the existing car body structure.
A new reinforcing structure for the resin body 1 can be constructed. In addition, a resin body 1 and a rear pillar member 9 are also included.
Since they are bolted to the vehicle body, the relative positional relationship between the two cannot be kept strictly constant. Therefore, when screwing the connection bracket 10 to the resin body 1 and the rear pillar member 9, variations in the positional relationship between the resin body 1 and the rear pillar member 9 pose a problem. However, in this example, the connection bracket 10
The screw through hole 14a of the second screw plate portion 14 of
is an elongated hole in the vertical direction, and the movable nut 15 whose position is adjustable in the vertical direction is used as the nut for screwing the bracket set screw 16. Therefore, the mounting position of the connecting bracket 10 relative to the mounting flange 7 can be adjusted in the vertical direction. It can be adjusted at Then, insert the screw through hole 13a of the first screw plate portion 13 of the connection bracket 10 into the bracket set screw 1.
Since the diameter of the thread is larger than that of thread 6, the attachment position of the connection bracket 10 to the rear pillar member 9 can be adjusted in the vehicle longitudinal direction and the vehicle width direction. Specifically, the first screwed part 13 is connected to the horizontal part 9a.
After determining the vertical position of the connecting bracket 10 by placing it on the bracket fixing plate part 12a from below, the mounting flange 7 and the second screw fixing plate part 14 are screwed together to make the vertical adjustment. It's over. After that, the first screw plate part 13 is attached to the bracket fixing plate 12.
By simply tightening the screws to a, in addition to the above-mentioned vertical adjustments, adjustments can be made in the longitudinal and vehicle width directions. In this case, as described above, the screw through hole 14a of the second screw plate part 14 is a long hole in the vertical direction, and the nut is vertically adjustable, so that the mounting flange 7 and the rear pillar member 9
Even if there are vertical variations in the positional relationship with
The bracket set screw 16 can be screwed onto the mounting flange 7 and the second screw fixing plate portion 14 without any problem. In addition, the screw through hole 13a of the first screw plate portion 13 is inserted into the bracket set screw 16.
Since the screw diameter is larger than that of the first screw plate part 13, even if there are variations in the relative positional relationship between the mounting flange 7 and the rear pillar member 9 in the longitudinal direction and the vehicle width direction, the bracket set screw 16 can be easily connected to the first screw fixing plate part 13. It can be screwed onto the bracket stopper plate 12a without any problem. 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. The connection bracket 10 can be screwed to the resin body 1 and the rear pillar member 9 without any problems by absorbing the variations in the connection bracket 10. In other words, the mounting structure of the connection bracket 10 of this example is such that variations in the relative positional relationship between the resin body 1 and the rear pillar member 9 can be tolerated. Moreover, when adjusting the mounting position of the connection bracket 10, there is no need to perform complicated adjustment work as described above, and it is only necessary to perform a simple work that is almost the same as a normal screw tightening work. Therefore, the connection bracket 10 can be easily attached. Further, on the side of the mounting flange 7, a movable nut 15 is used as the nut screwed into the bracket set screw 16, and the nut body 15b is held by the nut case 15a. Therefore, when tightening the screws between the connecting bracket 10 and the mounting flange 7, there is no need to enter the narrow space between the rear pillar member 9 and the mounting flange 7 to hold each nut. It's very easy to do. By the way, the scope of the present invention is not limited to the above-mentioned embodiments, and for example, the screw through holes of the first screw-fastening part and the second screw-fastening part of the connection bracket may all be shaped like holes. Also,
The connection bracket may be screwed to mounting flanges formed on the legs of the rear pillar member and the side wall of the resin body, respectively. Furthermore, the method of connecting the connecting bracket to the resin body and rear pillar member can be modified in various ways other than screwing.
