Description

[Detailed Description of the Invention] This invention relates to a vehicle body structure for supporting a load at the rear end of the floor of a truck bed, and particularly relates to a load-bearing structure of a corner post of the floor.

The truck bed structure is sometimes provided with a corner post as a reinforcing structure, and the general manner of assembly of this type of corner post is as shown in FIG. A pillar plate 2 having a U-shaped cross section, that is, a plate body consisting of a front plate 2a, a side plate 2b, and a shoulder plate, is erected on the left and right sides of the gate, thereby forming a hollow prismatic column with the side gate 3 as one side. .

However, in the conventional load-bearing structure of corner posts,
By installing a cross member 5 of the vehicle body under the rear end 1a of the floor, the load applied to the corner post 4 is stopped by the cross member 5.
A conventional supporting structure will be specifically explained with reference to FIGS.

First, the cross member 5 consists of l pairs of cross-running angle members 6. γ, and left and right beam members 8 with a U-shaped cross section that extend between the left and right sides of both angle members 6 and 1 and connect them to the art material 6.7, and the loading platform is connected to the cross member 5. In the assembled state, the load applied to each column surface of the corner post 4 is supported by the cross member 5 in the following manner.

(a) Front plate 2a (Fig. 3) Its lower end is attached to the rear end 1a of the floor at the intermediate part between the front angle member 6 and the rear angle member 7, so the load of the front plate 2a is transferred to the rear of the floor. It is supported by the bending stress of the end 1a.

(b) Shoulder plate 2c (FIG. 3) Its lower end is attached to the end of the rear angle member 7, so the load of the shoulder plate 2C is directly supported by the cross member 5.

(c) Side plate 2b (Fig. 4) Its lower end is added to the rear end 1a of the floor above the girder 8, so the load of the side plate 2b is directly transferred to the cross member 5.
Supported by

(d) Side gate 3 (FIG. 4) Its lower end is attached to the side edge of the rear end 1a of the floor, so the load of the side gate 3 is supported by the bending stress of the rear end 1a of the floor.

Incidentally, the reference numeral 9 in the figure indicates a skirt panel formed by the side gate 3, and this panel 9 is not particularly designed to maintain strength.

In the conventional load-bearing structure formed in this way, the two sides of the corner post 4 are supported indirectly via the rigid stress of the rear end 1a of the floor as described above, so that the live load on the column side is Corner post 4 and floor rear edge 1 according to
Deformation stress is generated in the attachment portion between the side gate 3 and the rear end 1a of the floor, and as a result, the welded portion between the side gate 3 and the rear end 1a of the floor tends to break.

The present invention solves the above-mentioned drawbacks by attaching simple reinforcing bodies to both ends of the cross member.In other words, the purpose of the present invention is to provide a corner post that will not cause breakage at the base of the corner post. The purpose is to provide a load-bearing structure for the post.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

In the load carrying structure of the embodiment, as shown in FIGS. 5 and 6, the cross member 10 is formed by welding reinforcing bodies 11 to the left and right ends of the cross member 5, respectively. Thus, the reinforcement body 11 includes an upper plate 11a forming an L-shaped plane, a front plate 11b and a horizontal plate 11c vertically formed along the outer edge of the upper plate 11a, and a collar 11 at the end of the front plate 11b.
d, a collar 11e at the lower edge of the front plate 11b, and a collar 11f at the lower edge of the horizontal plate 11c.

Furthermore, when the loading platform is assembled on the cross member 10, as shown in FIGS. 7 and 8, the load applied to each column surface of the corner post 4 is transferred to the cross member 10 II in the following manner. It will be done.

(a) Front plate 2a (Fig. 7) Its lower end is attached to the front edge of the reinforcement upper plate 11a integrally with the notch end of the floor rear end 1a, so the load on the front plate 2a is , directly supported by the cross member 10.

(b) Stone plate 2c (FIG. 7) Its lower end is attached to the end of the rear angle member 1, so its load is directly supported by the cross member 10.

(c) Side plate 2b (FIG. 8) Its lower end is attached to the notched end of the floor rear i1a on the girder 8, so its load is directly supported by the cross member 10.

(d) Side gate 3 (FIG. 8) Its lower end is attached to the side edge of the reinforcement horizontal plate 11c, so its load is directly supported by the cross member 10.

In this way, in the load-carrying structure of the embodiment, all of the live loads applied to the four column faces of the corner post 4 are directly supported by the cross member 10, so that the base of the corner post 4 is Only compressive stress is applied,
Therefore, no breakage occurs in the base.

As described above, according to the load-carrying structure of the corner post according to the present invention, since the reinforcing body is fixed to the cross member,
The live load is effectively carried by the cross member, which has the practical effect of increasing the rigidity of supporting the cargo bed of the vehicle body.
