Description

[Detailed Description of the Invention] The present invention relates to a sliding door prevention device for an automobile.

For example, a conventional automobile sliding door has a first
It is as shown in the figure and the second figure. FIG. 1 is a perspective view of an example of a conventional sliding door structure seen from inside the vehicle in a state immediately before fully closing, and FIG. 2 is a cross-sectional view taken along the line - in FIG. 1 with the door fully closed. Reference numeral 12 indicates an outer panel and an inner panel that constitute the door 1, 21 and 22 indicate an outer panel and an inner panel that constitute the vehicle body 2, and the door 1 has a single hinge 3 on the vehicle body 2.
is supported via a sliding mechanism 9. In the case where the dovetail 4 and the striker 5 are not provided, when the door 1 is just before fully closed, the part where the door 1 is supported by the hinge 3 becomes the rear end of the door 1, as shown in the first figure, and is cantilevered. Since the front end of the door 1 tends to swing and lowers due to the weight of the door, it not only interferes with the lower part of the vehicle body 2 and makes it difficult to close the door 1 smoothly, but also causes the door 1 to press the weather strip 6 and bend it. There is a drawback that the sealing function between the weather strip 6 and the door 1 is deteriorated due to the reaction force in the direction B in FIG. 2 that sometimes occurs. To solve this drawback, for example, a dovetail 4 is provided at the front end of the inner panel 12 of the door 1, and a striker that engages with the dovetail 4 is provided at the door opening edge of the outer panel 21 of the vehicle body 2 facing the dovetail 4. 5 is provided, and when the door is closed, the dovetail 4 enters into the recess 53 of the striker 5 in the direction of arrow A in FIG. In addition to making it possible to close the door 1 smoothly, the engagement between the dovetail 4 and the striker 5 keeps the door 1 pressed against the weather strip 6, thereby achieving a sealing function between the weather strip 6 and the door 1. I try to maintain it.

However, in such a conventional door structure, it is necessary that the dovetail 4 and the striker 5 have high dimensional accuracy, and the dovetail 4 is inserted into the recess 53 of the striker 5 from the direction of arrow A in FIG. The dovetail 4 does not enter into the recess 53 of the striker 5 and the striker 5 closes when the front end of the door 1 is swinging. Not only may the door 1 interfere with the peripheral protrusions 51 and 52, making it impossible to achieve a smooth closing operation of the door 1, but also the dovetail 4
As a result, the dovetail 4 and striker 5 are unable to maintain engagement with the striker 5 to counter the buckling of the door 1, and as shown in FIG. There are disadvantages such as compressing the living space of people.

In addition, as a known technology of this type,
There is a publication number 77324.

The present invention was developed in order to solve the above-mentioned drawbacks, and it not only makes it possible to reliably guide the door to the normal closed position, but also sufficiently prevents the buckling of the door in the event of a side impact collision. This is to prevent pressure.

The present invention will be explained below with reference to the drawings.

FIG. 4 is a perspective view of an embodiment of the sliding door structure of the present invention in a state immediately before fully closing, as seen from inside the vehicle;
FIG. 5 is a partial cross-sectional view of the sliding door structure of the present invention in a fully closed state, and FIG. 6 is a cross-sectional view taken along the - line in FIG. 5.

That is, in the present invention, a door 1 consisting of an outer panel 11 and an inner panel 12 is supported by a single hinge 3 on a vehicle body 2, and is configured to open and close (slide) via a sliding mechanism 9.

Inner panel 1 on the opposite side of door 1 hinge 3
A wedge 7 is attached to the lower end of the vehicle body 2, and a striker 8 that engages with the wedge 7 is attached to the door opening peripheral edge 200 of the vehicle body 2 that faces the wedge 7 when the door is closed.

Specifically, this outer panel opening periphery 200 includes an outer panel 210 and an inner panel 22.
0 to form a box-shaped cross section, and a stepped portion 212 is formed on the outer panel 210.
An opening 21 is provided in the step vertical surface portion 214 of this step portion 212.
6 is formed.

The striker 8 is formed into a funnel shape that roughly follows the rotation locus (indicated by the arrow in FIG. 6) of the door 1 during the final closing period (that is, from just before the door closes to when the door is fully closed), and the bottom wall 81 is shaped like a funnel. Outer panel 2
The bolt 3 is placed on the step plane part 218 of 10.
Fixed by 00 bond. The tapered portion of the striker 8 passes through the opening 216.

On the other hand, the wedge 7 includes a base portion 70 connected to the door inner panel 12 with bolts 302, and an arm portion 72 that protrudes from the base portion 70 toward the vehicle body 2.
and a slider 71 made of synthetic resin fitted to the tip of this arm portion 72, and the arm portion 72 is formed into a tapered shape that roughly follows the funnel shape of the striker 8.

With this configuration, the door 1 is in a state just before being fully closed as shown in the fourth diagram, and the door 1 is in a cantilevered state.
Even if the door 1 is closed when the front end of the slider 7 is downward, or even if the door 1 is closed when the front end of the door 1 is swinging, the slider 7
1 is the bottom wall 81 and side walls 82, 83 of the striker 8
The door 1 is guided in sliding contact with the weather strip 6, and the door 1 is guided to the normal closed position while correcting its position, and the door can be reliably prevented from lowering without interfering with the vehicle body 2. The seal between the door 1 and the weather strip 6 is Functions can be maintained stably.

In particular, since the striker 8 is formed in a funnel shape, it can be stably and reliably guided even if the door 1 is rotated from a considerably misaligned state.

Also, even after the door is closed, wedge 7 and striker 8
Since the wedges 7 and the strikers 8 are securely engaged and are engaged in a deep part of the vehicle body 2, that is, inside the opening 216 of the side sill outer panel 210, the wedge 7 and the striker 8 are disengaged in the event of a side collision. This is very effective in terms of safety because it can sufficiently resist the buckling of the door 1, suppress the deformation of the door, and prevent the interior space from being compressed.

As described above, according to the present invention, not only can the door be reliably guided to the normal closed position to prevent the door from falling down, but also
It can exhibit extremely useful effects as a side collision countermeasure.
