Description

  The present invention relates to a sliding door interference preventing structure for preventing interference between a fuel lid and a sliding door which are attached to a fuel supply portion of a vehicle so as to be freely opened and closed.

  The fuel refueling part of the vehicle is usually provided on the side surface on the rear side of the vehicle body, and a fuel lid that covers the fuel filler opening is provided to be openable and closable. Further, some minivan type vehicles and the like employ a slide door as a door on the rear seat side. In this type of vehicle, an opening position of the fuel lid overlaps on a slide track on the rear side of the slide door.

For this reason, as a technology for this type of vehicle, a sliding door interference prevention structure that prevents simultaneous opening of the sliding door and the fuel lid has been devised (see, for example, Patent Document 1).
This sliding door interference prevention structure is provided with an urging rod that is spring-biased in the protruding direction at the edge of the fuel refueling part on the vehicle body side to bring the fuel lid into a minute open state, and a door opening restriction mechanism is provided on the sliding door. The urging rod and the door opening restriction mechanism are interlocked so that the door opening restriction mechanism operates when the urging rod protrudes. Therefore, when this interference prevention mechanism is adopted, the sliding door can be freely opened while the fuel lid is closed and the biasing rod is retracted, and when the fuel lid is opened and the biasing rod protrudes, the door is opened. The opening operation of the sliding door is prohibited by the operation of the restriction mechanism.

  By the way, as a technique of the opening / closing part of the fuel lid, a technique using a push lifter that alternately repeats the protrusion maintaining state and the pulling maintaining state every time a pressing operation is received is known. This push lifter can switch the fuel lid between the closed position and the minute open position by repeatedly pressing through the fuel lid.

  Currently, in a vehicle using this push lifter for the opening and closing part of the fuel lid, it is considered to apply the above-described sliding door interference prevention mechanism.

  However, when the push-lifter of the fuel lid and the door opening restriction mechanism of the sliding door are simply linked, the opening of the sliding door can be restricted when the push-lifter protrudes, but the push lifter is in the retracted state. However, when the fuel lid is forcibly pushed up with a fingertip, there is a possibility that the sliding door and the fuel lid interfere with each other.

  Therefore, the present invention is intended to provide a sliding door interference prevention structure that can reliably prevent the sliding door and the fuel lid from interfering with each other even when a push lifter is used for the fuel lid.

The invention according to claim 1, which solves the above problem, is a sliding door that prevents simultaneous opening of a sliding door (for example, a sliding door 11 in an embodiment described later) and a fuel lid (for example, a fuel lid 10 in an embodiment described later). In the interference prevention structure, the protrusion maintaining state and the retracting maintaining state are alternately repeated every time the pressing operation is performed through the fuel lid, and when the fuel lid is closed, the retracting maintaining state is established, and the projecting maintaining state is established. A push lifter (for example, a push lifter 15 in an embodiment described later) that makes the fuel lid a micro-open state, and the fuel lid is locked to the push lifter when the fuel lid is closed and the push lifter is in a retracted state. And Lid locking means for releasing the locking of the fuel lid and the push lifter when the shredder is kept in the protruding state and the fuel lid is in a minute open state (for example, the engagement convex portion 35 and the engagement in the embodiments described later). And a door opening restricting means (for example, a door opening restricting device 25 in an embodiment described later) for locking the sliding opening of the sliding door when the push lifter is in the projecting maintenance state. The lid locking means includes an engagement recess (for example, an engagement recess 36 in an embodiment described later) provided in one of the fuel lid and a vehicle body side member to which the fuel lid is attached, and the other. Engagement projections provided on the member and engageable with the engagement recesses (for example, engagement in the embodiments described later) A protrusion 35), and the engagement recess abuts the engagement protrusion and supports the load of the fuel lid in a minute opening state of the fuel lid when the push lifter is in a projection maintaining state. A load supporting wall (for example, a load supporting wall 39a in an embodiment described later) is provided .
As a result, when the fuel lid is closed and the push lifter is pulled in and maintained, the fuel lid and the push lifter are locked by the lid locking means, and the opening operation of the fuel lid is restricted even if the fuel lid is forcibly pushed up by the fingertip. . Further, when the push lifter is pressed from this state to maintain the protruding state, the engagement between the fuel lid and the push lifter by the lid locking means is released.

  According to a second aspect of the present invention, in the sliding door interference prevention structure according to the first aspect, the push lifter is a vehicle body side member that supports the fuel lid so as to be opened and closed (for example, a fuel adapter 14 in an embodiment described later). ).

  According to a third aspect of the present invention, in the sliding door interference prevention structure according to the first or second aspect, the fuel lid is in the sliding state when the push lid is in the projectingly maintained state and the fuel lid is in a minute open state. The rotation is restricted to an angle that does not enter the sliding track of the door.

  According to the first aspect of the present invention, when the fuel lid is closed and the push lifter is in the retracted state, the fuel lid and the push lifter are locked by the lid locking means, and the fuel lid is forcibly opened over the fingertip. Therefore, the interference between the slide door and the fuel lid when the push lifter is retracted can be reliably prevented.

  According to the second aspect of the present invention, since the push lifter is installed on the vehicle body side member that supports the fuel lid so that the fuel lid can be opened and closed, the linkage between the door opening restricting means and the push lifter is facilitated, and the structure is simplified and manufactured. Can be facilitated.

  According to the third aspect of the present invention, when the push lifter is in the projecting and maintaining state, the fuel lid is restricted to an angle that does not enter the slide track of the slide door, so that the interference between the slide door and the fuel lid is further prevented. It can be regulated reliably.

In the case of this embodiment, the neck portion 32 is formed to have a substantially elliptical cross section, the short diameter side matches the width direction of the locking hole portion 41, and the long diameter side is set to extend along the extending direction of the locking hole portion 41. Has been.

  In the case of this locking portion, as shown in FIG. 10, when the fuel lid 10 is operated in the opening direction from the closed state, the protruding direction of the operating rod 16 of the push lifter 15 and the opening direction of the fuel lid 10 intersect. Therefore, the head 33 of the rod 16 is displaced toward the rotating shaft (hinge shaft 10 a) with respect to the fuel lid 10 in accordance with the protruding operation of the operating rod 16. In the case of this embodiment, when the fuel lid 10 is closed and the operating rod 16 is retracted, the head 33 is displaced to the position of the locking hole 41, and when the operating rod 16 protrudes and the fuel lid 10 is in a minute open state. The head 33 is displaced to the position of the release hole 42.

  Further, the operating rod 16 abuts against the hole edge of the engagement / disengagement control hole 40 at the shoulder portion 34, but the first inclined wall 37 forming the hole edge of the engagement / disengagement control hole 40 has a shape as shown in FIG. 10. In addition, a curved surface 37a is formed. The curved surface 37a is provided such that when the fuel lid 10 rotates in the vicinity of the closed position, the shoulder 34 always abuts on the front surface regardless of the rotation position of the fuel lid 10, and the first inclined wall is provided. The center of 37 has a curved shape that bulges in the direction of the push lifter 15.

  Further, as shown in FIG. 8, the end blocking wall 39 of the engagement recess 36 increases in thickness toward the release hole 42 of the engagement / disengagement control hole 40, and the thick portion is connected to the load support wall 39a. Has been. The load support wall 39a abuts against the head 33 of the engaging projection 35 when the fuel lid 10 is in a minute open state, and supports the load of the fuel lid 10 on the head 33.

  In FIG. 7, reference numeral 45 denotes a lock engaging portion formed on the back surface of the fuel lid 10, and a claw of a lock device (not shown) installed on the fuel adapter 14 side engages with the lock engaging portion 45. It is possible.

  In the above configuration, when the fuel lid 10 in the open state is closed, the operator places a hand on the fuel lid 10 and presses the lid 10 to rotate in the closing direction. When the fuel lid 10 is rotated in the closing direction in this way, first, the head 33 and the neck 32 of the engagement convex portion 35 on the push lifter 15 side are inserted into the release hole portion 42 of the engagement concave portion 36 on the lid 10 side, After that, the shoulder portion 34 of the engaging convex portion 35 comes into contact with the edge of the engagement / disengagement control hole 40 of the engaging concave portion 36, so that a pressing load is input to the push lifter 15. When a load is further applied to the fuel lid 10 from this state, the shoulder portion 34 slides on the first inclined wall 37 along the hole edge of the engagement / disengagement control hole 40 and the neck portion 32 moves in the engagement / disengagement control hole 40. Displace. Finally, the push lifter 15 is retracted to the maximum retracted position, and the head 33 and the neck 32 of the engaging convex portion 35 are stopped at the locking hole 41.

Thereby, the push lifter 15 is brought into the retracted state, and the fuel lid 10 is locked in the closed state by the engagement of the engaging convex portion 35 and the engaging concave portion 36 (the head portion 33 and the locking hole portion 41). become. Therefore, even if the fuel lid 10 is forcibly pushed up by hand from this state, the fuel lid 10 is not opened.
Further, when a lock knob (not shown) is operated from the vehicle interior in this state, the claw of the lock device engages with the lock engagement portion 45 of the fuel lid 10 and the fuel lid 10 is locked. In this state, as shown in FIG. 11 (A), the locking claw 29 of the door opening restricting device 25 falls forward, and the lock on the slide door 11 is released.

  Further, when the lock knob is released from the vehicle interior in this state and then the lid 10 is pressed by an operator to open the fuel lid 10, the pressing force is pushed through the shoulder 34 of the engaging convex portion 35 to push the lifter. 15, the operation rod 16 of the push lifter 15 protrudes forward in response to the input of the pressing force. When the operating rod 16 protrudes in this way, the shoulder portion 34 of the engagement convex portion 35 slides on the first inclined wall 37 along the hole edge of the engagement / disengagement control hole 40, and the head of the engagement convex portion 35 is in the meantime. The portion 33 and the neck 34 are displaced along the engagement / disengagement control hole 40 toward the release hole 42. When the push lifter 15 moves forward to the maximum projecting position, the fuel lid 15 is brought into a minute open state, and the head 33 is positioned in the release hole 42.

  As a result, the push lifter 15 is kept in the protruding state, and the engagement between the fuel lid 10 and the push lifter 15 (engagement between the engagement recess 36 and the engagement protrusion 35) is released. When the fuel lid 10 is completely opened from this state, the operator places his / her hand on the fuel lid 10 and rotates the fuel lid 10 by a manual operation.

  Further, when the operation rod 16 of the push lifter 15 is in the projection maintaining state as described above, as shown in FIG. 11B, the locking claw 29 of the door opening restricting device 25 is caused via the interlocking wire 20, As a result, the opening of the slide door 11 is regulated. Therefore, even if it is going to open the slide door 11 from the state which the fuel lid 10 opened in this way, the slide door 11 cannot be opened, and interference with the slide door 11 and the fuel lid 10 is prevented reliably.

  As described above, the interference prevention structure of the slide door 11 employed in the vehicle 1 regulates the opening operation of the slide door 11 when the push lifter 15 is in the projecting maintenance state, and regulates the slide door 11 when the push lifter 15 is in the retracting maintenance state. Since the operating rod 16 of the push lifter 15 and the locking claw 29 of the door opening restricting device 25 are linked so as to be released, the sliding opening of the sliding door 11 when the push lifter 15 protrudes and the fuel lid 10 is opened is performed. Can be locked.

Further, in this interference prevention structure, when the push lifter 15 is in the protruding maintained state, the engagement of the engagement convex portion 35 on the push lifter 15 side and the engagement concave portion 36 on the fuel lid 10 side is released, and the push lifter 15 Since the engaging convex portion 35 and the engaging concave portion 36 are engaged with each other when the pull-in is maintained in the retracted state, the fuel lid 10 is forcibly raised by hand while the push lifter 15 remains in the retracted state. Therefore, it is possible to lock the sliding opening of the sliding door 11 whenever the fuel lid 10 is opened.
Therefore, in this interference prevention structure, it is possible to reliably prevent interference between the slide door 11 and the fuel lid 10 while adopting the push lifter 15 in the opening / closing part of the fuel lid 10.

  Further, in the interference prevention structure of this embodiment, since the push lifter 15 is installed on the fuel adapter 14 side, the structure on the fuel lid 10 side can be simplified to improve the workability during refueling, and the push lifter There is an advantage that the interlocking wire 20 for interlocking 15 and the door opening restricting device 25 can be easily and stably routed on the vehicle body side.

  By the way, in the case of this embodiment, the opening angle of the fuel lid 10 when the push lifter 15 is in the projection maintaining state is set to a setting angle at which the fuel lid 10 does not enter the slide track of the slide door 11. There may be provided a restricting means for restricting the opening angle of the fuel lid 10 to a set angle with a weak spring force that can be opened by a human hand when 15 is in the protruding maintenance state. In this case, even if a situation where the sliding opening of the sliding door 11 cannot be locked for some reason occurs, the interference between the sliding door 11 and the fuel lid 10 can be reliably prevented.

  In addition, this invention is not limited to said embodiment, A various design change is possible in the range which does not deviate from the summary.
