Description

  The present invention relates to a sliding door structure for an automobile having a sliding door that opens and closes. More specifically, the present invention prevents a person or luggage in the vehicle from colliding with the slide door from the inside of the vehicle to the outside of the vehicle and causing the slide door to open when the automobile having the slide door collides with something. Related to the structure.

  Patent Document 1 discloses a side part structure of an automobile provided with a slide-type side door that prevents the side door from entering the vehicle during a side collision. Here, the intrusion into the side door vehicle is prevented by utilizing the fact that the side sill incorporating the side door sliding mechanism has a relatively high rigidity.

  More specifically, in the event of a side collision, the door slide mechanism opening provided on the side sill opens outward in the vehicle width direction, toward the vehicle interior fixed to the lower end of the side door. This is a structure that suppresses the intrusion of the side door into the vehicle by engaging the extending engaging member.

JP 2008-15928 A

  In Patent Document 1, a measure for preventing the door on the side collided in the case of a side collision from entering the vehicle is taken into consideration. However, when a side collision occurs, passengers and luggage in the vehicle collide with the door on the opposite side from the inside. In addition, even if the collision is from a direction other than the side, an occupant or a luggage may collide with the slide door.

  A single door such as a front door has a front side connected to the vehicle body by a hinge, and a rear side fixed to the vehicle body by a lock. Therefore, even when force is applied from the outside of the vehicle to the inside of the vehicle or when force is applied from the inside of the vehicle to the outside of the vehicle, there are few cases where the door is opened by an impact.

  However, in the case of a slide door, the door and the vehicle body are held by the slide mechanism on the upper and lower parts on the front side, but there is no one that holds the door and the vehicle body on the upper and lower parts on the rear side. That is, if a force is applied to the rear side portion of the slide door from the inside of the vehicle to the outside of the vehicle, the rear upper portion of the slide door is displaced to the outside of the vehicle, which may cause a gap between the door and the vehicle body.

  Furthermore, since the sliding door that has started to be displaced does not have a structure that restricts the separation from the vehicle body, the door opens greatly, leading to a passenger or baggage being thrown out of the vehicle.

The present invention has been conceived for the purpose of solving the above problems. More specifically, the sliding door structure of the present invention includes an interference member fixed at one end to the inside of the sliding door at the rear of the sliding door,
A restricting member disposed at a position corresponding to the other end of the interference member at a position where the sliding door is closed and fixed to a vehicle body member;
The slide is located at the position where the slide door is closed, the other end of the interference member is located on the inner side of the regulating member, and is located at a predetermined distance from the regulating member in the vehicle width direction. It is a door structure.

  In the slide door structure of the present invention, the other end of the interference member further has a through hole in a portion facing the restriction member, and the restriction member protrudes in a portion opposite to the other end of the interference member. It is a sliding door structure which has a part.

The sliding door structure of the present invention is
The interference member and the regulating member have a sliding door structure arranged at both the rear portion of the sliding door and the upper and lower portions of the vehicle body member.

  In the present invention, when the sliding door is closed, the other end of the interference member fixed to the sliding door at one end is located on the inner side of the regulating member fixed to the vehicle body member, and the vehicle width direction Therefore, even if a force is applied from the inside of the vehicle to the outside of the vehicle and the side door is displaced, the other end of the interference member and the regulating member abut against each other, thereby locking the displacement of the slide door. The sliding door can be prevented from opening outside the vehicle.

  In addition, since the other end portion and the restricting portion of the interference portion are respectively provided with a through hole and a protruding portion, when the sliding door is displaced, these engage with each other, and the front and rear direction or the vertical direction of the sliding door is engaged. There is an effect that the deviation is also locked.

It is a figure showing the whole automobile of the present invention. It is a figure showing the relationship between a slide door rear upper part and C pillar upper part. It is a figure which shows an engaging part. It is a figure which shows a to-be-engaged part. It is a figure which shows a mode that the slide door displaced.

  FIG. 1 is a view showing an example of an automobile 1 having a sliding door structure of the present invention. The automobile 1 has an A pillar 2, a B pillar 3, and a C pillar 4. Each pillar is connected to a side sill 5 at the bottom of the vehicle body and a roof rail 6 at the top of the vehicle body. Each of these pillars, the side sill 5, and the roof rail 6 constitute a vehicle body member.

  In the automobile 1, a front door 7 is disposed between the A pillar 2 and the B pillar 3, and a rear door 8 is provided between the B pillar 3 and the C pillar 4. The front door 7 is a door of a type called a front hinge rear opening type, and the rear door 8 is a sliding door (hereinafter referred to as “sliding door 8”).

  The sliding door 8 is fitted so that the upper roller and the lower roller arranged at the front upper part and the lower part of the front and the center roller arranged at the center of the rear part can roll in the rail arranged in the vehicle body, It is supported movably.

  On the vehicle body side, first, an upper guide rail 9 is disposed in the roof rail 6. The upper guide rail 9 is provided between the C pillar 4 and the B pillar 3. In the vicinity of the B pillar 3, the upper guide rail 9 enters the inside of the vehicle from the roof rail 9 in a curved shape.

  Next, a lower guide rail 10 is disposed at a lower portion between the B pillar 3 and the C pillar 4. The lower guide rail 10 is also disposed between the C pillar 4 and the B pillar 3, and enters the inside of the vehicle from the vicinity of the B pillar 3.

  A rear side outer panel 11 and a rear side window 12 are disposed behind the C pillar 4. A center rail 13 is embedded in the rear side outer panel 11. The center rail 13 extends rearward from the C pillar in accordance with the width that the slide door 8 opens. In the vicinity of the C pillar, when the slide door 8 is closed, the center rail 13 is formed so as to be gently wound from the outside of the vehicle to the inside of the vehicle in order to move from the outside to the inside of the vehicle.

  On the other hand, an arm is fixed to the upper front portion of the slide door 8, and an upper roller is provided on the arm. An arm is also fixed to the front lower side of the slide door 8, and a lower roller is provided on the arm. The upper roller and the lower roller are fitted so that they can roll in the upper guide rail 9 and the lower guide rail 10, respectively. Further, a center roller is provided at the rear center portion of the slide door 8 and is fitted so as to roll in the center rail 13.

  The slide door 8 slides back and forth as the upper roller, the lower roller, and the center roller roll in the upper guide rail 10, the lower guide rail 11, and the center rail 13, respectively. Each rail is bent from the vehicle exterior direction to the vehicle interior direction on the embedded front side. Therefore, when the sliding door front portion slides from the rear to the front and becomes near the B pillar, the entire sliding door fits in the vehicle while drawing a curve from the vehicle outer side to the vehicle inner side, and the outer surface becomes flush. These are structures that are usually employed for sliding doors.

  FIG. 2 shows the structure of the rear upper part of the sliding door 8 of the present invention. A solid line indicates a position where the slide door 8 is closed, and a two-dot chain line indicates a position before the slide door 8 is closed. A one-dot chain line with an arrow represents a movement locus of the slide door 8. The C pillar 4 is formed by welding the rear side outer panel 11 and the rear side inner panel 14. As already described, the slide door 8 moves forward as indicated by a one-dot chain line from a state opened rearward on the vehicle side, and is closed while moving toward the vehicle inner side.

  Here, a door stopper 20 is fixed to the upper part of the C pillar 4, and a regulating member 23 is integrally formed on the door stopper 20. An interference member 30 is fixed to the rear upper part of the slide door 8. First, the regulating member 23 and the interference member 30 will be described individually.

  FIG. 3 shows only the upper part of the C pillar 4, and FIG. 4 shows the upper rear part of the sliding door 8. Referring to FIG. 3, the door stopper 20 has a crank-type bracket shape. One end 21 is fixed to the vertical wall of the C pillar 4 by a screw 22 or the like, and an elastic body 23 such as hard rubber is disposed at the other end. When the slide door 8 is opened, the door stopper 20 is regulated by the upper roller arm in the upper front portion of the slide door coming into contact with the elastic body 23 and serves as a stopper for the slide door 8.

  The door stopper 20 includes a restriction member having an arm 25 extending vertically from an arm portion 24 extending forward from a connection portion 21 to the C pillar, and a protrusion 26 protruding from the vehicle outer side to the vehicle inner side at the tip of the arm 25. 28. Further, the rear portion of the protrusion 26 has a cut-off shape 27 cut from the rear outside the vehicle toward the front inside the vehicle.

  Reference is now made to FIG. The interference member 30 has a shape having a mounting surface 31 extending in the cross-sectional direction at one end of the U-shaped cross-sectional member. The mounting surface 31 and the vehicle interior panel 4 ′ of the slide door 8 are firmly fixed by screws 32 or the like. The attachment surface 31 is one end of the interference member 30. The other end 34 of the interference member 30 is formed substantially in parallel with the slide door and has a through hole 33. Therefore, the through hole 33 is formed in a substantially perpendicular direction on a plane parallel to the slide door 8. Here, the end face of the end portion 32 of the interference member 30 is denoted by reference numeral 35.

  Referring to FIG. 2 again, when the slide door 8 changes from the open state to the closed state, the through hole 33 of the interference member 30 of the slide door 8 is fixed to the C pillar 4 that is the vehicle body member. 28 are arranged at opposite positions. At this time, the other end portion 32 having the through hole 33 of the interference member 30 is located on the vehicle inner side than the protrusion portion 26 of the regulating member 28. And the through-hole 33 and the projection part 26 of the control member 28 oppose each other by a predetermined distance 40 in the vehicle width direction.

  The cut-off shape 27 at the protrusion 25 of the restricting member 28 is for preventing the sliding door 4 from coming into contact with the end surface 35 of the interference member in the trajectory where the slide door 4 moves from the outside of the vehicle to the inside of the vehicle. This is because when the end face 35 of the interference member and the protrusion 25 come into contact with each other, the slide door 4 cannot be fitted in the vehicle.

  Next, the function of the sliding door structure of the present invention will be described with reference to FIG. FIG. 5 is a view of the C pillar 4 and the closed slide door 8 as seen from above the vehicle body. The position where the slide door 8 is closed is indicated by a two-dot chain line.

  Now, when an automobile is subjected to an impact such as a collision, there are cases where personnel or luggage in the vehicle collide with the slide door 8 from the inside of the vehicle toward the outside of the vehicle. That is, a strong pressure 50 is applied to the slide door from the inside of the vehicle to the outside of the vehicle. The sliding door needs a mechanism for locking so that it does not open or disengage even if a considerable pressure is applied.

  In the front portion of the slide door 8, the upper upper upper roller and the upper guide rail, and the lower lower roller and the lower guide rail are in a fitted state. Since these fittings and the respective guide rails are relatively strong, the displacement of the sliding door due to the pressure 50 from the inside of the vehicle to the outside of the vehicle can be locked.

  On the other hand, the rear portion of the slide door 8 is held mainly by fitting and locking of the center roller and the center rail. Although the holding by the lock is strong, the slide door 8 is disposed in the vicinity of the center at the rear. Therefore, there is nothing in the upper part or the lower part of the rear part of the slide door 8 that resists pressing from the inside of the vehicle to the outside of the vehicle. In particular, the rear upper part of the sliding door may be displaced from the inside of the vehicle toward the outside of the vehicle.

  However, in the sliding door structure of the present application, as shown in FIG. 5, when the door is closed, the end portion 32 having the through hole 33 of the interference member 30 is positioned at a predetermined distance 40 from the protrusion portion 26 of the regulating member 26. It is located inside, and the through-hole 33 and the protrusion 26 are arranged in a positional relationship facing in the vehicle width direction.

  Therefore, even if the rear portion of the slide door 8 is displaced from the vehicle inner side toward the vehicle outer side by the pressing 50 from the vehicle inner side toward the vehicle outer side, the interference member 30 moves by a predetermined distance 40 (45), and the through hole 33 When is engaged with the protrusion 26, the displacement behind the slide door is locked. Further, since the projection 26 is engaged with the through hole 33, the slide door 8 is not only displaced from the inside of the vehicle to the outside of the vehicle, but also is displaced in the vertical and forward / backward direction of the slide door.

  As described above, the sliding door structure of the present invention includes an interference member fixed at one end on the inner side of the sliding door at the rear portion of the sliding door, and a position corresponding to the interference member at the position where the sliding door is closed. A regulating member fixed to the vehicle body member, and at the position where the slide door is closed, the other end of the interference member is located on the vehicle interior side with respect to the regulating member, and a predetermined distance is provided between the regulating member and the regulating member. Therefore, even if a person or baggage in the vehicle moves and is pressed from the inside of the vehicle to the outside of the vehicle, the sliding door is displaced by the other end of the interference member and the regulating member. Since it is locked, the sliding door never opens.

  In addition, although the interference member and the regulating member of the present invention are arranged in the upper part at the rear of the slide door and the upper part of the C pillar serving as the vehicle body member corresponding thereto, they may be arranged in the lower part.

  Further, the predetermined distance 40 is a distance for locking the slide door when the rear portion of the slide door is removed, and thus it is desirable that the predetermined distance 40 is short. On the other hand, if this distance is too short, the sliding doors will come into contact with each other when they fit into the vehicle. It can be determined appropriately depending on the arrangement of the interference member and the regulating member.

  Further, the restricting member may be disposed at a position corresponding to the interference member at the position where the slide door is closed. Here, the corresponding position is a position away from the position of the other end of the interference member by a predetermined distance on the vehicle outer side in the vehicle width direction. In the description of the present embodiment, the case where the restricting member is formed integrally with the stopper 20 is shown, but the present invention is not limited to this. As long as it is fixed to the vehicle body member and disposed at a position corresponding to the interference member, a regulating member may be disposed separately from the stopper.

  The present invention can be widely used not only for sliding doors of automobiles but also for the structure of sliding doors of other vehicles.
