Description

TECHNICAL FIELD The present invention relates to a method for assembling a vehicle resin floor to fix a resin floor pan to a rocker panel.

[Problems to be Solved by Prior Art and Invention]

Generally, as shown in FIG. 4, a floor pan 10 made of steel plate is used.
When coupled to the locker panel 12, the structure is such that the lower end of the locker inner panel 14 of the locker panel 12 and both ends of the floor pan 10 in the vehicle width direction are spot-welded.

In this structure, it is necessary to prevent water from entering the upper surface of the floor pan 10 by the sealer 11 extending over the entire vehicle width direction terminal of the floor pan 10 in the longitudinal direction of the locker panel 12.

By the way, at present, a vehicle using a resin floor pan 16 has been proposed (as an example, an open technology number 84-002012).
issue).

This makes it possible to reduce the weight of the vehicle and improve rust prevention. As shown in FIG. 5, this resin floor pan 16 cannot be welded to the locker panel 12, unlike the steel plate floor pan 10 shown in FIG. Therefore, the widthwise ends of the resin floor pan 16 are fixed to the rocker panel 12 via the bolts 18 and nuts 20.

However, in such a structure, since the load F (see FIG. 5) downwardly applied to the resin floor 16 is reliably supported, the number of bolts 18 and nuts 20 is increased, resulting in cost increase and workability in assembling. Is reduced. Further, since water may enter through the gap between the locker panel 12 and the resin floor pan 16, it is necessary to tightly interpose the seal member 21 and the like between them.

In view of the above facts, the present invention has an object to provide a method for assembling a vehicle resin floor that is easy to assemble and does not allow water to enter.

[Means and Actions for Solving Problems]

The vehicle resin floor assembling method according to the present invention is a vehicle resin floor assembling method in which a resin floor pan is assembled and fixed to a locker panel, and both ends of the resin floor pan in the vehicle width direction are attached to the vehicle. The standing part bent upward and the bent part whose tip end is bent outside the vehicle are provided, and the standing part of the resin floor pan is biased toward the center of the vehicle to be elastically deformed and held. While being conveyed from the lower side of the vehicle to the rocker panel correspondingly, and after being arranged at a predetermined position, the urging force is released to restore the shape of the resin floor pan so that the bent portion is closely attached to and supported by the upper surface of the rocker panel. I am trying.

Therefore, it is easy to assemble and both ends of the resin floor in the vehicle width direction are extended to the upper surface of the locker panel.
It is not necessary to interpose a seal member or the like for preventing water leakage between the locker panel and the resin floor pan.

〔Example〕

1 and 2 show an embodiment of a vehicle to which the method for assembling a vehicle resin floor according to the present invention is applied.

This floor pan 22 is made of FRP (fiber reinforce plastic) with elastic force, and the direction of arrow A in FIG. 1 is the front-rear direction of the vehicle. At the center of the vehicle, there is a mesh case, propeller (not shown). A recessed portion 24 for disposing a shaft or the like is formed.

Both ends of the floor pan 22 in the vehicle width direction are attached to the locker panel 26. As shown in FIG. 2, the rocker panel 26 is composed of a rocker inner panel 28 and a rocker outer panel 30, and the floor pan 22 is attached to the rocker inner panel 28.

At both ends of the floor pan 22 in the vehicle width direction, standing portions 32 that are bent upward of the vehicle are formed, and correspond to the side surfaces of the Lotka inner panel 28.

Flange portions 34 are formed at both end portions of the locca inner panel 28 in the vehicle vertical direction. Corresponding to this, the flange part 36 is also formed on the locker outer panel 30,
Each is polymerized.

The end portions of the reinforcement 44 are sandwiched between the flange portion 34 and the flange portion 36, and the three panels are joined together and spot welded to form a closed cross-section structure.

As shown in FIG. 2, an L-shaped bent portion is formed on the vehicle upper side of the Lotka inner panel 28 to provide a rectangular recess 50. The recess 50 is a space in which the wire harness 51 extending in the vehicle front-rear direction is arranged.

Corresponding to the recess 50, a bent portion 52 that is bent toward the vehicle outer side is formed at the tip of the standing portion 32 of the floor pan 22.

A plurality of circular holes 54 are provided in the bent portion 52, and bolts 56 are respectively inserted in the bent portion 52. After penetrating the locker inner panel 28, a nut 58 and a screw 58 previously welded to the inner surface side of the locker inner panel 28 are screwed. Floor pan by combining
The 22 and the locca inner panel 28 are joined together.

A carpet 60 is laid on the upper surface side of the floor pan 22 with a cushioning material 59 interposed therebetween.

Next, a procedure for assembling the floor pan 22 to the locker panel 26 will be described.

When arranging the floor pan 22 on the Lotka inner panel 28,
As shown in FIG. 3 (A), the floor pan 22 is transported from below the vehicle by a transport mechanism (not shown).

Before starting this conveyance, a circular hole 54 provided in the bent portion 52
Insert the pin 64 of the assembling jig 62 into the vehicle and urge it toward the center of the vehicle (direction of arrow A in FIG. 3B) to bend the bent portion 52 upright.
It should be placed inside the vehicle.

As a result, the erected portion 32 of the floor pan 22 is elastically deformed, and then while maintaining this state, the floor pan 22 is conveyed to the upper side of the vehicle so as to correspond to the Lotka inner panel 28 (see FIG. 3 (C)). .

In this case, the tip of the bent portion 52 is on the inside of the vehicle with respect to the base of the standing portion 32, and therefore, the Rotakka inner panel during transportation.
28 and the bent portion 52 do not interfere with each other.

Here, by canceling the insertion of the pin 4 of the assembly jig 62 into the circular hole 54 (see FIG. 3 (D)), the shape of the standing portion 32 is restored, and the standing portion 32 is restored. 32 is brought into contact with the side surface of the Lotka inner panel 28, and the bent portion 52 is brought into contact with the recess 50,
Supported.

Next, as shown in FIG. 3 (E), the bolt 56 is inserted into the circular hole 54.
The floor pan 22 can be fixed to the loccaine inner panel 28 by inserting and inserting it into the nut 58.

In this way, the standing part that extends to the floor pan 22 above the vehicle
Since 32 is provided, water does not enter from between the floor pan 22 and the Lotka inner panel 28, and there is no need to interpose an adhesive or a sealing member between them, so that the number of assembly steps is reduced. It can be reduced and the cost can be reduced.

Further, when fixing the floor pan 22 and the Lotka inner panel 28 with the bolt 56 and the nut 58, the floor pan 22 is supported at a predetermined position in a suspended state by the bent portion 52, so the floor pan 22 is not It is not necessary to support the jig or the worker, and the assembling work becomes easy.

Although the floor pan 22 is formed of FRP in this embodiment,
Other materials may be used as long as they have elasticity.

〔The invention's effect〕

As described above, the vehicle resin floor assembling method according to the present invention is a vehicle resin floor assembling method in which the resin floor pan is assembled and fixed to the locker panel, and the vehicle floor width direction of the resin floor pan is the same. A standing portion whose both ends are bent toward the upper side of the vehicle and a bent portion whose tip end is bent toward the outside of the vehicle are provided, and the standing portions of this resin floor pan are biased toward the center of the vehicle to elastically deform. , While holding it, it is conveyed from the lower side of the vehicle to the rocker panel in a corresponding manner, and after being placed at a predetermined position, the biasing force is released to restore the shape of the resin floor pan so that the bent portion is brought into close contact with the upper surface of the rocker panel. Since it is supported by means of the above, it has an excellent effect that the assembling work is easy and water does not enter.
