Description

TECHNICAL FIELD The present invention relates to a rear gate hinge mounting reinforcement structure applied to a rear gate mounting portion of a vehicle carrier mounted so as to be openable and closable.

2. Description of the Related Art A conventional rear gate hinge attachment reinforcing structure will be described with reference to FIGS.

FIG. 5 is a perspective view showing the appearance of a small truck, and a rear gate 13 that can be opened and closed is provided on the luggage carrier at the rear of the driver's seat. The rear gate 13 is attached to the rear end cross sill 11 via a hinge 12, and a hinge link hose 1'is used as a reinforcing material in a portion where the hinge 12 is attached to the rear end cross sill 11. This hinge ring hose 1 '
For example, as shown in FIG. 7, a thick iron plate is formed and bolt holes 8 are drilled, and the bolts and nuts 15 and 16 are fastened together with the hinge 12 and the rear end cross sill 11. The rear body floor 18 has one end joined to the end of the rear end cross sill 11 and extends toward the driver's seat, and is supported by a cross sill 17 arranged in parallel with the rear end cross sill 11 in the middle thereof.

The arrow 14 indicates the opening / closing direction of the rear gate 13.

Problems to be Solved by the Invention According to the above-described conventional example, the weight of the rear gate and the force generated by opening and closing act on the rear end cross sill via the hinge. Since this force is concentrated on the hinge mounting portion of the rear end cross sill, a hinge link hose has been conventionally used as a reinforcing material. However,
In the conventional rear gate hinge link hose, the plate thickness at the hinge mounting portion of the rear end cross sill is merely increased to partially reinforce, and therefore the rigidity as the structure is improved, that is, the rear end cross sill, the cross sill, and the rear sill. A reinforcement effect that increases the rigidity of the rear floor structure composed of the body floor and the like could hardly be expected.

Means for Solving the Problems The present invention is to solve the above-mentioned problems, and is applied to a rear gate mounting portion of a vehicle carrier that is mounted on a rear end cross sill via a hinge so as to be openable and closable. In a hinge phosphorus hose that reinforces a mounting portion to a rear end cross sill, a thin plate is formed into a groove shape including a bottom plate and a pair of side plates, and a first rim that is connected to the rear end cross sill that is provided at one end and a first rim that is provided at the other end are provided. A second rim that is coupled to the cross sill that is supported on the bottom surface of the rear body floor of the luggage platform, a third rim that is coupled to the rear body floor provided at the upper end of the side plate, and a hinge mounting rim that is coupled to the hinge. The first rim, the rear end cross sill, the hinge mounting rim, and one end of the hinge are coupled to each other, and the second rim and the clip are joined together. A rear gate hinge mounting and reinforcing structure is characterized in that the hinge ring hose portion is configured so as to form a substantially closed cross section by connecting at least one of a sill and a third rim and the rear body floor.

Action According to the above-described means, the hinge ring hose portion of the rear gate is formed into the groove-shaped structure, so that the rigidity of the hinge ring hose portion itself is improved. Further, this hinge link hose portion is connected to the rear end cross sill and the hinge via the rim, and is also connected to at least one of the cross sill and the rear body floor. Not only does this increase the strength of the rear gate hinge mounting portion, but also has the effect of increasing the rigidity of the rear floor structure.

Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a perspective view showing an example of the shape of a hinge link hose 1 which constitutes the hinge link hose portion of the present invention. The hinge link hose 1 comprises a thin iron plate as a bottom plate 2 and a pair of facing side plates 3. It is formed into a groove shape. A first rim 4 is provided so as to project from one end (rear end side) of the bottom plate 2, and a second rim is provided at the other end of the side plate 3, that is, an end of the side plate 3 on the opposite side (front end side) from the first rim 4. The rim 5 is provided so as to project. Further, a third rim 6 and a hinge mounting rim 7 are provided on the upper end of the side plate 3 so as to project, and the hinge mounting rim 7 having the bolt holes 8 is provided with an appropriate inclination.

FIG. 2 shows the rear gate mounting portion of the vehicle carrier,
Rear gate through hinge 12 to rear end cross sill 11
13 is installed. The rear gate 13 fixed to one side of the hinge 12 can be opened and closed in the direction of arrow 14, and the other side of the hinge 12 is fastened to the rear end cross sill 11 and the hinge mounting rim 7 of the hinge link hose 1 by bolts and nuts 15 and 16. There is. In the hinge link hose 1, the first rim 4 has a rear end cross sill 11, and the second rim 5 has a cross sill 17 supported on the bottom surface of the rear body floor 18 of the luggage carrier.
And, the third rim 6 is connected to the rear body floor 18, respectively, and the rear end cross sill 11 and the cross sill
Together with 17 and the rear body floor 18, etc., a rear floor structure having a substantially closed cross section is formed. In addition, hinge ring hose 1
The connection with at least one of the cross sill 17 and the rear body floor 18 may be omitted, and thereby a rear floor structure having a substantially closed cross section can be formed.

As described above, since the rear end cross sill 11 and at least one of the cross sill 17 and the rear body floor 18 are coupled by the hinge link hose 1, the hinge link hose 1 has a rigidity that the hinge link hose 1 itself has as a groove structure. By this, not only is the hinge mounting portion reinforced, but also the rear floor structure having a substantially closed cross section is formed, so that it also acts as a reinforcing material for the rear floor structure. More specifically, the hinge link hose 1 functions in the same way as the ribs are attached to the rear floor structure to reinforce it, and therefore the rigidity of the rear floor structure is greatly improved. It is possible to more effectively reinforce the hinge mounting portion in cooperation with the improvement of the rigidity of, and it is also effective to improve the rigidity of the entire vehicle body.

3 and 4 show another embodiment, which is different from the above-mentioned embodiments in that the third rim 6 is provided with the recesses 6a and 6b.

In the concave portion 6a, the end portions of the rear end cross sill 11 and the rear body floor 18 are overlapped and the three plates are joined together, but the provision of the concave portion 6a does not cause a step on the floor surface. In the recess 6b, the rim 17 of the cross sill 17 is
Although a is connected to the rear body floor 18 and the third rim 6, there is still no step on the floor surface. in this way,
By tightly connecting the respective members, the rigidity of the rear floor structure is further improved.

Advantageous Effects of Invention According to the present invention, the rear gate hinge link hose is combined with at least one of the rear end cross sill and at least one of the cross sill and the rear body floor to form a rear floor structure having a substantially closed cross section. It has the effect of improving the rigidity of the body.

Therefore, the rigidity of the rear floor structure is improved in addition to the rigidity of the hinged hose itself having the groove-shaped cross section, which not only secures the strength of the hinge mounting part, but also contributes to the improvement of the reliability of the entire vehicle body. it can.
