Abstract

<P>PROBLEM TO BE SOLVED: To provide a door opening/closing device capable of opening at least a part of a doorway without allowing a door to interfere with vehicle body trim parts even when the vehicle body trim parts such as a lid is projected to the outside of a vehicle body. <P>SOLUTION: When a rear door is slid to open an opening, a rotation release mechanism 110 is slid together with a guide bracket 76 and a movable piece 120 presses a projected piece 129 to rotate a control plate 108. Therefore, the rotational restriction of a link 76 around a shaft 74 is released. A wire is pulled by the release of the lid. When the movable piece is rotated, it does not press the projected piece 129, and the control plate 108 is not rotated. Therefore, in this state, the rotational restriction of the link 72 around the shaft 74 is not released. Since the rotation of the rear door after sliding is restricted though the opening of the rear door is opened by the amount of the sliding in this state, the rear door does not abut on the lid. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a door opening and closing device that opens and closes a vehicle door by sliding and rotating.

  One example of a door structure that opens and closes a vehicle entrance / exit is a swing door. In this type of swing door, the vehicle body and the door are connected by a link mechanism, and by first turning the arm member constituting the link mechanism, the door that closes the entrance / exit opening is outside the vehicle and substantially the same. When the vehicle is rotated rearward and the arm member is further rotated, the door moves substantially rearward of the vehicle. Thereby, the entrance / exit is opened.

  On the other hand, in this type of swing door, a lid for closing the fuel injection port may be provided on the movement trajectory of the door when opening the entrance / exit. When refueling, rotate the lid with respect to the vehicle body to expose the fuel inlet, remove the lid provided on the fuel inlet, insert the fuel gun into the fuel inlet, Supply fuel.

  Thus, when the lid is rotated with respect to the vehicle body in order to expose the fuel injection port, the lid protrudes substantially outside the vehicle from the vehicle body. If the door is moved in the direction in which the entrance opening is opened in such a protruding state of the lid, the door interferes with the lid. A configuration for preventing the door from interfering with the lid is disclosed in Patent Document 1 below.

In the configuration disclosed in Patent Document 1, a link switch that mechanically interlocks with the rotation of the lid with respect to the vehicle body is interposed between the switch for opening and closing the door and the power source. When the lid is rotated to expose the fuel inlet, the link switch is turned off. In this state, even if the door opening / closing switch is operated, the door does not move. Thereby, the interference of the door with respect to a lid can be prevented.

As the door slides, the movable member engages with the door or the interlocking member interlocked with the door.

  Further, the movable member engaged with the door or the interlocking member engages with the rotation start member and moves the rotation start member in the rotation start direction. Thus, the rotation start member moves in the rotation start direction to allow (allow) the door to rotate (second opening operation), and further, the door rotates to open the entrance / exit. .

  On the other hand, in a state where the vehicle body equipment protrudes to the outside of the vehicle, the movable member is detached from the engagement position, so that the movable member is not engaged with the door or the interlocking member. As a result, the movable member does not engage with the rotation start member, and the rotation start member does not move in the rotation start direction. For this reason, in this state, the rotation of the door is not permitted, and the door is forcibly stopped before being rotated.

  Thus, since the door can be prevented from rotating and the door can be forcibly stopped in the middle of all opening operations, the door can be prevented from coming into contact with the vehicle body equipment protruding to the outside of the vehicle.

  As described above, in the door opening and closing device according to the first aspect of the present invention, the second opening operation of the door is prevented in the middle of all opening operations in a state where the vehicle body equipment projects to the outside of the vehicle. Since the door can be forcibly stopped, it is possible to prevent the door from coming into contact with the vehicle body equipment protruding outward from the vehicle.

  In the door opening and closing apparatus according to the second aspect of the present invention, the vehicle body equipment projects outwardly without providing a separate member that interferes with the door and the member interlocking with the door and prevents the second opening operation. The second opening operation of the door in the state can be prevented.

  In the door opening and closing apparatus according to the third aspect of the present invention, since the movable member constitutes both the movement preventing means and the releasing means, the door is attached to the vehicle body equipment projecting outward from the vehicle with a simple structure as a whole. The contact can be prevented.

  In the door opening and closing apparatus according to the fourth aspect of the present invention, since the rotation of the door after the sliding movement can be prevented, it is possible to prevent the door from interfering with the vehicle body equipment protruding to the outside of the vehicle.

The detection pin 154 is provided in a state of penetrating the support cylinder 156 penetrating the casing 146 and the side wall 16 of the vehicle body along the substantially vehicle width direction on the rear side of the vehicle with respect to the rotational axis of the lid 38. In a state where the lid 38 closes the opening 32, one end of the detection pin 154 faces the lid 38 substantially on the rear side of the vehicle with respect to the rotational axis of the lid 38.

  On the other hand, the other end of the detection pin 154 is engaged with the other arm of the rotation lever 150 inside the casing 146. The rotating lever 150 biases the detection pin 154 in the opening direction of the lid 38. Therefore, when the lid 38 is closed with the lid 38, one end of the detection pin 154 presses against the lid 38 and rotates the rotation lever 150 in the direction opposite to the arrow R5 in FIG. 6B against the urging force. Thus, the tension of the wire 138 is weakened. However, as shown in FIG. 7B, when the lid 38 is opened, the detection pin 154 moves greatly outward of the vehicle, and the rotation lever 150 rotates in the direction of arrow R5 in FIG. 6B. . As a result, the wire 138 is pulled, and the movable piece 120 rotates as shown in FIG.

<Operation and effect of the present embodiment>
Next, the operation and effect of the present embodiment will be described.

  When the opening 14 is closed to the rear door 30 in the vehicle 12 to which the door opening / closing device 10 is applied, the contact portion 104 is in contact with the rotation restricting portion 102 as shown in FIG. For this reason, in this state, even if the rod 92 tries to rotate together with the link 72 in one direction around the support wall 68 (in the direction of arrow R1 in FIG. 2), the rotation restricting portion 102 rotates the rod 92 via the lock lever 94. Therefore, the link 72 cannot be rotated. Therefore, when the rear door 30 is moved in a direction inclined substantially rearward of the vehicle with respect to the outside in the vehicle width direction in order to open the opening 14, the side of the rear door 30 where the mounting bracket 60 is fixed (rear) Side), but the link 72 does not rotate around the support wall 68 on the side (front side) where the guide bracket 76 of the rear door 30 is fixed. On the other hand, it slides in the direction inclined substantially rearward of the vehicle, that is, in the direction of the arrow S1 in FIGS. By sliding the rear door 30, the facing state between the end portion on the vehicle front side of the rear door 30 and the end portion on the vehicle rear side of the front door 28 along the vehicle width direction is canceled.

  Further, when the rear door 30 slides in this way, the slider 80 fixed to the slider fixing portion 78 of the guide bracket 76 is guided by the guide groove 86 of the guide rail 84 and as shown in FIG. The other end side of the slider 80 approaches the guide rail 84 located at the position. When the slider 80 slides in this manner, the restriction release portion 130 of the movable piece 120 approaches the protruding piece 129. When the restriction release unit 130 approaches the protruding piece 129, the restriction releasing unit 130 constituting the movable piece 120 as the movable member abuts (engages with) the protruding piece 129 forming the control plate 108 as the rotation start member. Then, when the projecting piece 129 is pressed by the restriction release portion 130, the control plate 108 rotates in one direction around the shaft 109 (in the direction of arrow R4 in FIG. 2).

  When the other end of the rod 92 rotates together with the control plate 108 in one direction around the shaft 109 (in the direction of the arrow R4 in FIG. 2), one end of the rod 92 moves around one side of the shaft 96 (in the direction opposite to the arrow R2 in FIG. 2). Further, the lock lever 94 rotates together with one end of the rod 92 to one side around the shaft 96 against the urging force of the shaft 96. As a result, as shown in FIG. 3, the contact portion 104 moves outward from the flange portion 100, and the opposed state of the rotation restricting portion 102 and the contact portion 104 is eliminated. Thus, when the opposing state of the rotation restricting portion 102 and the contact portion 104 is canceled, the rotation restriction of the link 72 is released. Therefore, if the rear door 30 is moved in this state in a direction inclined substantially rearward of the vehicle with respect to the outside in the vehicle width direction, the rear door 30 rotates around the shaft 58 and the support wall 68 (swing: second). The opening 14 is moved substantially to the rear side of the vehicle, thereby opening the opening 14.

  On the other hand, when the opening 14 is closed by the rear door 30 and the lid 38 is rotated in the direction of the arrow R1 in FIG. 6B and the opening 32 is opened, the lid is opened as shown in FIG. 7B. 38 protrudes outward in the vehicle width direction from the side wall 16 of the vehicle body. Thus, the lid 38 tries to be separated from the tip of the detection pin 154 by rotating the lid 38 outward in the vehicle width direction.

  As described above, the detection pin 154 is engaged with the rotation lever 150 and is pushed out of the casing 146 by the urging force of the fuel filler side urging means that urges the rotation lever 150 to one side around the shaft 152. Is being energized. For this reason, when the lid 38 tries to move away from the tip of the detection pin 154, the rotation lever 150 causes the detection pin 154 to move outside the casing 146 by the biasing force of the filler opening biasing means, as shown in FIG. Push to. When the rotation lever 150 rotates in this way, the wire 138 is pulled against the urging force of the return spring 144. Thereby, from the state shown in FIG. 6 (A), the movable piece 120 rotates around the shaft 128 (in the direction of arrow R5 in FIG. 6 (A)) as shown in FIG. 7 (A). As described above, when the movable piece 120 rotates to one side around the shaft 128, the restriction release portion 130 also rotates to one side around the shaft 128 and disengages from the engagement position.

  Therefore, in this state, even if the guide bracket 76 is slid to the vehicle rear side as described above, the restriction release portion 130 does not come into contact with the protruding piece 129. For this reason, the control plate 108 as the interlocking member is not rotated to one side around the shaft 107, and the opposed state between the rotation restricting portion 102 and the contact portion 104 is maintained. Therefore, in this state, the rotation restriction of the link 72 as the interlocking member is maintained, and the rear door 30 corresponding to the slide of the guide bracket 76 with respect to the guide rail 84 is included in the full opening operation of the rear door 30 when the opening 14 is opened. The first opening operation (sliding) can be performed, but the second opening operation (turning) of the rear door 30 corresponding to the rotation of the link 72 cannot be performed.

  For this reason, the rear door 30 is forced to stop further door opening operation in a state in which a part of the opening 14 is opened (that is, a state between the fully closed state and the fully opened state of the opening 14). Thus, the rear door 30 does not reach the position where it abuts on the lid 38, and the rear door 30 can be prevented from abutting on the lid 38 that opens the opening 32 and protrudes substantially outward in the vehicle width direction.

  Moreover, in the present embodiment, out of the full opening operation of the rear door 30, the second opening operation (turning) cannot be performed, but the first opening operation (sliding) can be performed. Thereby, although the opening 14 is not fully opened, a part is opened. Therefore, for example, even when the lid 38 is protruded substantially outward in the vehicle width direction when refueling or the like, a part of the opening 14 can be opened and a relatively small load can be taken in and out.

  Further, in the present embodiment, the opposed state between the rotation restricting portion 102 and the contact portion 104 is maintained by turning the restriction releasing portion 130 to one side around the shaft 128 and detaching from the engagement position. Thus, the rotation restriction of the rear door 30 is maintained. For this reason, it is not necessary to separately provide a lock mechanism for directly locking the rear door 30 and the link 72 in conjunction with the rotation of the lid 38 when the opening 32 is opened.

  Furthermore, in the present embodiment, the second of the rear door 30 corresponding to the rotation of the link 72 relative to the side wall 16 of the vehicle body can be achieved simply by rotating the movable piece 120 to disengage the restriction release portion 130 from the engagement position. The opening operation (turning) can be prevented, and the second opening operation (turning) of the rear door 30 can be performed only by rotating the movable piece 120 and returning the restriction release portion 130 to the engaged position. In this way, it is possible to easily switch between prevention and release of the second opening operation (rotation) of the rear door 30 with a simple configuration that allows the movable piece 120 to rotate.

  In the present embodiment, the sliding of the rear door 30 with respect to the link 72 (that is, the first opening operation) and the rotation of the link 72 with respect to the side wall 16 of the vehicle body (that is, the second opening operation) are not performed at the same time. However, if the rotation of the link 72 with respect to the side wall 16 of the vehicle body is started after the sliding of the rear door 30 with respect to the link 72 is started, the vehicle body of the link 72 before the sliding of the rear door 30 with respect to the link 72 is completed. The rotation with respect to the side wall 16 may be started (that is, the second opening operation is started in the middle of the first opening operation).

  In the present embodiment, the first opening operation is a slide with respect to the link 72 of the rear door 30, and the rotation of the link 72 with respect to the side wall 16 of the vehicle body is the second opening operation. However, the present invention is not limited to such an embodiment. For example, the rotation of the link 72 relative to the side wall 16 of the vehicle body is a first opening operation, and the sliding of the rear door 30 with respect to the link 72 is a second opening operation. In the configuration, that is, the slide of the rear door 30 with respect to the link 72 is started after the rotation of the link 72 with respect to the side wall 16 of the vehicle body is started. It is good also as a structure which prevents that abuts.

  Further, in the present embodiment, the lid 38 is configured as the vehicle body equipment in the scope of the claims, but the vehicle body equipment is not limited to the lid 38 and moves to the outside of the vehicle. The equipment is not limited to a specific form of the car body equipment as long as the equipment projects to the outside of the vehicle from the car body, such as a part of the window glass.

  In this embodiment, the link 56 is supported by the side member 20 on the rear side of the opening 14. However, the link 56 may be supported on the side member 20 above the opening 14.

  Furthermore, in the present embodiment, the rear door 30 is slid with respect to the link 72 and the link 72 is rotated with respect to the side wall 16 of the vehicle body, whereby the rear door 30 is opened and closed. 72 is slid with respect to at least one of the rear door 30 and the side wall 16 of the vehicle body, and the link 72 is rotated with respect to the rear door 30 and the side wall 16 of the vehicle body so that the rear door 30 is opened and closed. Good.

  In the present embodiment, the vehicle 12 is not provided with a center pillar, but the vehicle 12 may be provided with a center pillar. In this case, the rear door 30 may be locked to the center pillar when the rear door 30 is fully closed.
