Description

  The present invention relates to a slide door structure provided on a side surface of a vehicle body and sliding along a guide rail provided on the side surface of the vehicle body to open and close the door opening.

  Conventionally, a link mechanism having a roller rotatably connected to a guide rail provided on the side surface of the vehicle body slides along the vehicle body longitudinal direction and opens and closes an opening provided on the side surface of the vehicle body. There is a sliding door having a latch of a lock mechanism inside a door having a closed structure composed of a door outer panel and a door inner panel. In order to make the sliding door slide smoothly, a gap is provided between the guide rail and the roller along the vehicle width direction, and the lock mechanism is located above the guide rail and is separated from the guide rail in the vertical direction. Without attaching to the outer surface of the door inner panel without any gap. (For example, see Patent Document 1)

JP, 8-338166, A (figure 5) The latch 10 of the lock mechanism is attached to the door inner panel 14 without a gap.

  When a load in the passenger compartment moves due to a side collision or the like and collides with the slide door, a large load is input to the slide door from the inside of the vehicle body to the outside of the vehicle body. The front end of the sliding door only moves along the vehicle width direction within the range of the gap between the upper and lower guide rails and the roller. On the other hand, because the door inner panel receives reaction force from the lock mechanism at the rear end of the slide door, the amount of movement of the door inner panel lock mechanism mounting part to the outside of the vehicle body is small. The part can move to the outside of the vehicle body by the gap along the vehicle width direction between the guide rail and the link mechanism. The slide door rotates around the lock mechanism, and the end of the slide door and the door opening of the vehicle body There is a possibility that a large opening is formed between the end portions.

  In addition, when the gap in the vehicle width direction between the lock mechanism and the door inner panel is larger than the gap in the vehicle width direction between the roller and the guide rail, if a large load is applied to the door inner panel, the door The connecting portion between the slide door and the link mechanism moves to the outside of the vehicle body until the inner panel starts to be deformed toward the outside of the vehicle body and there is no gap in the vehicle width direction provided on the roller and the guide rail. At this time, since the gap between the door inner panel and the lock mechanism remains, the door inner panel is further deformed toward the outside of the vehicle body until it comes into contact with the lock mechanism. For this reason, the locking mechanism mounting portion of the door inner panel moves larger than the link mechanism to the outside of the vehicle body, the sliding door rotates around the lower portion of the sliding door, and the end of the sliding door and the door opening edge of the vehicle body A large opening may be formed between them.

  Therefore, the present invention provides a slide door structure having means for suppressing the formation of an opening between the end portion of the slide door and the vehicle body when a large load is input from the inside of the vehicle body to the slide door.

In the sliding door structure of the present invention,
A gap provided along the vehicle width direction between the roller and the guide rail,
A gap provided along the vehicle width direction between the lock mechanism and the door inner panel;
Is the same size.

  According to the slide door structure of the present invention, a gap is provided along the vehicle width direction between the lock mechanism and the door inner panel provided at the rear end, and a large load is applied to the slide door from the inside of the vehicle body to the outside of the vehicle body. When it is input, the door inner panel of the sliding door is deformed, and the gap between the lock mechanism and the door inner panel is reduced, while the roller provided at the tip of the link mechanism and the guide rail extend along the vehicle width direction. The sliding door moves to the outside of the vehicle body by the gap provided. As a result, the sliding door is suppressed from rotating around the lock mechanism or the lower portion of the sliding door.

  Accordingly, the formation of an opening between the end portion of the slide door and the vehicle body is suppressed.
