Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a door mounting structure for an automobile, and more particularly to a door mounting structure for improving a door drop rigidity.

[0002]

[Prior Art]

Conventionally, an automobile door is mounted as shown in FIG. 6, for example. That is, in FIG. 6, the door 1 is attached to the vehicle body 2 so as to be openably and closably supported via two upper and lower hinges 3 and 4. According to such a door mounting structure, a downward force F acts on the door 1 due to the weight of the door 1 as shown in FIG. Means that a backward force F ₁ is applied to the lower hinge 4 and a forward force F ₂ is applied to the lower hinge 4.

The hinges 3 and 4 are specifically configured as shown in FIG. That is, the hinges 3 and 4 constitute a pillar 5 fixedly arranged inside the fender outer 2a on the vehicle body side. On the other hand, base portions 3a and 4a extending laterally (front in the case of the drawing) at the root portions of the hinges 3 and 4 are fixed by bolts 6 and nuts 7. Here, of the forces F ₁ and F ₂ applied to each of the hinges 3 and 4, the force F ₂ applied to the lower hinge 4, in particular, acts so as to rotate the hinge 4 counterclockwise in the drawing. Therefore, the region of the pillar outer 5 supporting the hinge 4 is reinforced by the outer reinforcement 8 and the retainer 9 so as not to be deformed by the force F ₂ .

[0004]

[Problems to be solved by the device]

 By the way, even in the door mounting structure configured and reinforced as described above, it cannot be said that the rigidity with respect to the door down (door down rigidity) is sufficient, and as shown in FIG. Since it will be deformed as shown in (B), and as a result a door drop will occur, it is necessary to take such a door drop into account and make the parting width relatively large. Therefore, the parting width becomes conspicuous in appearance, and the appearance is impaired.In some cases, even if such a parting width is taken, the door may become heavy when the door is opened or closed due to a door drop. However, it is possible that it may not be possible to close it completely by hitting the surrounding area. Therefore, there is a method of increasing the plate thickness of the pillar outer 5a and the outer reinforcement 8, but the weight is significantly increased, which is not preferable.

In view of the above points, the present invention realizes a vehicle door mounting structure that realizes reinforcement of the pillar outer and improves the door drop rigidity without significantly increasing the weight. The purpose is to.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, of the pillar outer and the pillar inner constituting the pillar for supporting the door, the one for the door mounting which is mounted to the surface of the pillar outer via the bolt. In a vehicle door mounting structure including a hinge, in the hinge mounting area of the pillar outer, a bracket fixedly arranged by spot welding or the like is provided on the back of the pillar outer on the pillar outer side. The bolt penetrates the bracket and is fixedly attached to the bracket.

[0007]

[Action]

 According to the above configuration, since the hinge is supported by the pillar outer and the bracket fixedly arranged on the back side of the pillar outer, when the load is applied to the hinge due to the weight of the door, the hinge receives the rotational moment. However, since the bolt for attaching the hinge to the pillar outer is also fixed to the bracket, the rotation of the hinge can be restrained not only by the pillar outer but also by the bracket. . Therefore, the pillar outer will not be deformed by the load applied to the hinge, and the door drop rigidity will be improved, and at that time, the only parts added to the conventional door mounting structure will be the bracket and the like. Since it is a relatively lightweight component, the weight will not increase significantly.

[0008]

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 shows an embodiment of a vehicle door mounting structure according to the present invention. In this door mounting structure 10, a hinge 11 is fixedly arranged inside a fender outer 12 on the vehicle body side. Of the so-called pillar outer 13a and pillar inner 13b that make up the pillar 13, the base portion 11a that extends laterally at the root of the hinge 11 is separated by the bolt 14 and the nut 15 from the pillar outer 13a. It is fixed.

The above-described structure is similar to the conventional door mounting structure shown in FIG. 6, but in the door mounting structure 10 according to the present invention, the door mounting structure 10 further includes a hinge mounting region of the pillar outer 13a. On the back side of the pillar outer 13a, there is provided a bracket 16 fixedly arranged by spot welding or the like to the side surface of the pillar 13 (pillar inner 13b in the case shown). The bracket 16 has a mounting hole (not shown) into which the tip of the bolt 14 is to be fitted. As a result, the bolt 14 is inserted into the collar 17 after penetrating the pillar outer 13a, penetrates the mounting hole of the bracket 16, and is fastened by the nut 15. The door mounting structure 10 according to the present invention is constructed as described above, and the hinge 11 has its base portion 11a fixed to the pillar outer 13a and the pillar outer 13a via the bolt 14, the nut 15 and the collar 17. It will be attached to the bracket 16 that is disposed in a specific manner. Therefore, the above-mentioned force F ₂ applied to the lower hinge is distributed to the pillar outer 13a and the bracket 16, so that the pillar outer 13a is less likely to be deformed and the hinge 11 tends to rotate left. Also, since the bolt 14 for attaching the hinge 11 is held by the bracket 16 at the tip thereof, counterclockwise rotation of the hinge 11 can be suppressed, and the door-down rigidity can be improved. Thus, even if the parting width around the door is relatively small, the door can be smoothly opened and closed, and the door can be mounted with a good appearance.

4 and 5 show an embodiment in which the present invention is applied to a rear door, in which the pillar 13 is located between the front door 18 and the rear door 19 and is located inside the vehicle body. -A pillar except that a bracket 16 is attached to a pillar outer reinforcement 13c for reinforcing the pillar outer 13a, and a seat belt retractor 20 is provided on the indoor side thereof. The configuration is similar to that of the first embodiment. In this case, due to the presence of the seat belt retractor 20, the bracket 16 can be provided even when the inner space of the pillar is relatively small, and similarly, the door down rigidity can be improved.

[0011]

[Effect of the device]

 As described above, according to the present invention, since the hinge is supported by the pillar outer and the bracket fixedly arranged on the back side of the pillar outer, when the hinge is loaded by the weight of the door or the like, Even if this hinge tries to rotate due to a rotational moment, the bolt for attaching the hinge to the pillar outer is also fixed to the bracket. Therefore, the hinge is rotated not only on the pillar outer but also on the bracket. Can also be suppressed by. Therefore, the load applied to the hinge does not deform the pillar outer, and the rigidity of the door is improved. Also, at that time, since the bracket is the only component that is loaded on the conventional door mounting structure, the weight does not increase significantly.

[0012] Thus, according to the present invention, by providing reinforcement of the pillar outer without a significant increase in weight, it is possible to provide an extremely excellent vehicle door mounting structure that can improve the door drop rigidity. Will be done.
