Description

Center Roller Bracket Fixing Structure for Slide Door for Van

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixed structure of a center roller bracket of a slide door for a passenger vehicle, and more particularly to a fixed structure of a bracket for connecting a center roller to a slide door in a door that is slidably opened and closed in a passenger vehicle. .

In general, the doors for passenger cars are hingedly connected to the vehicle body, while the driver's and passenger's doors are pivotally opened and closed like the passenger car's doors, but the rear seat doors are slidably opened and closed.

That is, the driver's door of the van is opened and closed by the hinge portion of the front of the passenger car, while the rear seat door is slidably connected to the vehicle body and is slidably moved left and right.

Therefore, the rear seat door, that is, the slide door of the van, is connected to the upper and lower parts and the middle part so as to slide on the vehicle body, of which a conventional connection structure of the center roller is shown in cross section in FIG.

As shown in the drawing, the vehicle body is composed of inner and outer side panels 1 and 2, and a weather strip 4 is fitted to upper end joints of the panels 1 and 2, respectively. The weather strip 4 is in close contact with the glass 5 of the slide door (not shown) to maintain airtightness.

The center rail 6 is fastened to the outer side panel 2 with a bolt, and a reinforcing panel 3 for strength reinforcement is abutted on the inner side of the outer side panel 2 at the bolt fastening portion.

On the other hand, the first bracket 7 is provided with a vertical roller 8 that is rotated about a horizontal axis and a horizontal roller 9 that is rotated about a vertical axis, so that each roller 8, 9 is provided with a center rail 6. It slides in friction contact with).

The first bracket 7 is not directly connected to the slide door, but is connected to the slide door via a second bracket (not shown).

2 is a perspective view of a conventional second bracket, as shown in the right portion of the second bracket 10 is a pair of pin holes 14, the first bracket is connected by a pin is formed in the longitudinal. On the left side, two mounting holes 11 and 12 are located on the horizontal line. In other words, the second bracket 10 is fixed to the slide door by fastening bolts to the two mounting holes 11 and 12.

However, the conventional second bracket 10 has a problem in that the mounting force is weak because there are two mounting holes located on the horizontal line. Therefore, the second bracket 10 is likely to be deformed due to the heavy slide door, and when the second bracket 10 is deformed, the rollers 8 and 9 do not come into close contact with the center rail 6 and thus are lifted. The problem that the opening and closing operation of the door is not made smoothly was caused.

Therefore, the present invention has been made to solve the problems caused by the conventional second bracket fixing structure, by strengthening the mounting force of the second bracket, the sliding door for a passenger vehicle that can prevent deformation of the second bracket It is an object to provide a center roller bracket fixing structure.

10-2nd Bracket 11,12,13-Mounting Hole

14-pinball

In order to achieve the above object, the present invention, a pair of pin holes are fixed to one side of the first bracket is fixed to the center bracket is installed on one side, the second bracket is formed with mounting holes in which the slide door is fixed to the other side In the structure for fixing to the slide door,

The mounting holes are formed at three positions of each vertex of the triangle, and the second bracket is fixed to the slide door by bolting at three points.

According to the above-described configuration of the present invention, the mounting holes are formed in three places corresponding to the positions of the vertices of the triangle, not located on the same line in the second bracket, and the bolts are fastened to the mounting holes, thereby being fixed to the slide door. The mounting force of the second bracket is greatly strengthened.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a perspective view of a second bracket according to the present invention;

For reference, in describing the configuration of the present embodiment, the same parts as in the prior art described at the beginning of the specification will be described mainly by omitting the repeated descriptions in order to avoid duplication of description.

As shown, the second bracket 10 of the present invention has almost the same shape as the prior art. That is, a pair of pin holes 14 having a first bracket (not shown) connected to the pin is formed in the right part, and in the left part, three mounting holes 11, 12, and 13 are different from the conventional one. Is formed and is fixed to the slide door (not shown) by fastening the bolt to these mounting holes 11, 12, and 13. As shown in FIG.

Among the mounting holes 11, 12 and 13, the lower two mounting holes 11 and 12 located on the horizontal line are the same as in the prior art, and the mounting holes 13 added in the present invention are the two mounting holes ( 11, 12) is formed in a position not collinear. More specifically, the third mounting hole 13 forms a triangular shape with the other two mounting holes 11 and 12, and each mounting hole 11, 12 and 13 forms a vertex of a triangle, a substantially right triangle. do.

When the mounting holes 11, 12, and 13 are formed as described above, the second bracket 10 is supported at three points so that the mounting force is strengthened, and in particular, due to the heavy slide door, The durability against one moment is also strengthened.

As described above, according to the present invention, since the second bracket 10 is supported at three points, it is possible to prevent deformation of the second bracket 10 due to the heavy slide door.

Therefore, due to the deformation of the second bracket 10, the center roller is lifted off the center rail, thereby preventing the situation in which the opening and closing operation of the slide door is not smooth.

On the other hand, the present invention is not limited to the above-described specific preferred embodiments, and various changes can be made by those skilled in the art without departing from the gist of the invention claimed in the claims. will be.
