It has been. The link side locking device 47 is electrically locked and unlocked with respect to the front striker 31 by electrically engaging and releasing a latch (not shown) with respect to the front striker 31. Then, the door body 14 is locked relative to the link member 24 so as not to rotate relative to the link member 24, and when the front striker 31 is unlocked, the door body 14 is relative to the link member 24 around the second rotation shaft 33. Turnable. Contrary to the above, the front striker 31 may be provided on the door body 14 side and the link side locking device 47 may be provided on the link member 24.

  As shown in FIG. 1, the door main body 14 includes a rear door that can be locked and unlocked with respect to a rear striker 50 attached to a rear pillar portion 49 that constitutes a rear edge portion of the opening 13 in the vehicle front-rear direction. An end-side locking device 51 is attached. The door rear end side locking device 51 is electrically locked and unlocked with respect to the rear striker 50 by electrically engaging and releasing a latch (not shown) with respect to the rear striker 50.

  A door outer handle 53 capable of rotating around the front side in the vehicle front-rear direction shown in FIG. 5A and sliding in the vehicle front-rear direction shown in FIG. 5B is attached to the outside of the door body 14. In addition, a sensor (not shown) for detecting whether the door outer handle 53 is rotated or slid is provided. The opening / closing operation of the door main body 14 is selected depending on whether the door outer handle 53 is rotated or slid. In addition, although not shown, two door opening / closing switches are provided on the vehicle interior side corresponding to one of the door main bodies 14, and the opening / closing operation of the door main body 14 depends on which one of the door opening / closing switches is operated. Selected.

  In such a door opening / closing structure of the first embodiment, as shown in FIG. 1, when the door body 14 is in the closed state in which the opening 13 is closed, the second rotation shaft is more than the first rotation shaft 19. Reference numeral 33 denotes a rear side in the vehicle front-rear direction, the link member 24 extends along the vehicle front-rear direction, and the door body 14 is arranged outside the vehicle body 14 along the vehicle front-rear direction. In this state, the link side lock device 47 is locked to the front striker 31, and the door rear end side lock device 51 is locked to the rear striker 50. In this way, the door body 14 is locked to the vehicle body 12 with the opening 13 closed. Further, in this state, the door main body 14 is locked to the door main body side pulley 35 by the pulley side locking device 44.

  If the sensor (not shown) detects that the door outer handle 53 has been rotated as shown in FIG. 5A from this closed state, for example, the control unit (not shown) FIG. 1 shows that the first opening / closing mode has been selected so as to rotate the first rotation shaft 19 around the first rotation shaft 19 while maintaining the posture along the radial direction of the first rotation shaft 19. As shown in the figure, the door main body 14 is unlocked to the rear striker 50 by the door rear end side locking device 51 while the door main body 14 is locked to the link member 24 by the link side locking device 47, and the pulley side locking is performed. The device 44 releases the lock of the door main body 14 with respect to the door main body side pulley 35 so as to be rotatable. In this state, the endless belt 36 is pulled by the traction drive unit 38 provided in the link member 24 so as to move the door body 14 side to the door body side pulley 35 side. Then, the vehicle body side pulley 21 is fixed to the vehicle body 12, and the door main body side pulley 35 is free with respect to the door main body 14. Therefore, as shown by a two-dot chain line in FIG. Rotate to rotate the door main body side pulley 35 around the first rotation shaft 19 so that the rear side in the vehicle front-rear direction of the door main body 14 moves in an arc shape outward and in the vehicle width direction. Then, the opening 13 is opened.

  On the other hand, when it is detected by a sensor (not shown) that the door outer handle 53 has been rotated again from this state, for example, the control unit uses the traction drive unit 38 provided on the link member 24 to move the endless belt 36. Is pulled in the opposite direction. Then, while rotating the door main body side pulley 35, the link member 24 and the door main body 14 are integrally centered on the first rotation shaft 19, and the rear side in the vehicle front-rear direction of the door main body 14 is set to the vehicle width direction inner side and the rear side. It is rotated so as to be moved in an arc shape, and the opening 13 is closed and the above-described closed state is obtained. That is, in the first opening / closing mode, the door body 14 is fixed to the link member 24 and pivots about the first pivot shaft 19 to open / close the opening 13.

  Further, when a sensor (not shown) detects that the door outer handle 53 has been slid, for example, as shown in FIG. 5B from the closed state, the control unit (not shown) The door main body 14 is locked to the rear striker 50 by the door rear end side locking device 51 while the locked state of the door main body 14 with respect to the door main body side pulley 35 by the pulley side locking device 44 is maintained. The door body 14 is unlocked with respect to the link member 24 by the link-side lock device 47, and can be rotated. In this state, the endless belt 36 is pulled by the traction drive unit 38 provided in the link member 24 so as to move the door body 14 side to the door body side pulley 35 side. Then, since the vehicle body side pulley 21 is fixed to the vehicle body 12 and the door main body side pulley 35 is fixed to the door main body 14, as shown by a two-dot chain line in FIG. The link member 24 rotates about the first rotation shaft 19 forward in the vehicle front-rear direction while rotating the door body 14 relative to the second rotation shaft 33. At this time, since the door main body side pulley 35 has the same diameter as the vehicle body side pulley 21 fixed to the vehicle body 12 side, the first rotation shaft 19 is centered while maintaining the same phase with respect to the vehicle body side pulley 21. Thus, the door body 14 locked to this moves in a circular arc around the first rotation shaft 19 to the front side while maintaining the posture along the vehicle longitudinal direction, that is, the posture when the opening 13 is closed. To open the opening 13.

  On the other hand, from this state, for example, when a sensor (not shown) detects that the door outer handle 53 has been slid again, the control unit causes the traction drive unit 38 provided on the link member 24 to move the endless belt 36 above. Tow the opposite. Then, the door main body side pulley 35 turns around the first rotation shaft 19 while maintaining the same phase with respect to the vehicle body side pulley 21, and the door main body 14 remains rearward while maintaining the posture along the vehicle longitudinal direction. It moves to the circular arc shape centering on the rotating shaft 19, closes the opening part 13, and will be in the above-mentioned closed state. That is, in the second opening / closing mode, the door body 14 opens and closes the opening 13 by rotating around the second rotation shaft 33 with respect to the link member 24 rotating around the first rotation shaft 19. Let

  According to the door opening / closing structure of the first embodiment described above, the link member 24 supported on the vehicle body 12 side so as to be rotatable about the first rotation shaft 19 is parallel to the first rotation shaft 19. The door main body 14 is rotatably supported via the second rotation shaft 33 provided. In the first opening / closing mode, the door main body 14 is locked to the link member 24 and is centered on the first rotation shaft 19. , The opening 13 is opened and closed in a pivotal manner. In the second opening / closing mode, the door body 14 is second with respect to the link member 24 that rotates about the first rotation shaft 19. By pivoting about the pivot shaft 33, the door body 14 can be moved in the posture when the opening 13 is closed and opened and closed. Therefore, the opening / closing operation can be selected according to the situation, and the structure for that can be simplified. Moreover, since it is not necessary to provide a slide rail, the inside of the door main body 14 can be satisfactorily covered with a lining.

  More specifically, in the first opening / closing mode in which the door main body 14 is rotated, the door main body 14 is locked to the link member 24 by the link side locking device 47 and the door main body side pulley 35 is locked by the pulley side locking device 44. In this state, the endless belt 36 is wound together with the fixed body-side pulley 21 on the vehicle body 12 side when the endless belt 36 is pulled by the traction drive unit 38. While rotating the door main body side pulley 35 with respect to the door main body 14, the link member 24 rotates about the first rotation shaft 19, and the door main body 14 locked to the link member 24 moves to the first rotation shaft 19. It opens and closes in a pivoting manner around the center. Further, in the second opening / closing mode in which the door main body 14 is moved in the posture when the opening 13 is closed, the door main body 14 can be rotated with respect to the link member 24 by the link side lock device 47 and the pulley side lock can be performed. The device 44 locks the door main body 14 with respect to the door main body side pulley 35. When the endless belt 36 is pulled by the traction drive unit 38 in this state, the endless belt together with the vehicle body side pulley 21 fixed to the vehicle body 12 side is provided. The link member 24 rotates about the first rotation shaft 19 while rotating the door main body pulley 35 around which the door 36 is wound, and the door main body 14 rotates together with the door main body pulley 35 for the second rotation. It rotates around the shaft 33. Thereby, the door body 14 moves in a circular arc shape to the front side in the posture along the vehicle longitudinal direction, that is, the posture when the opening portion 13 is closed, and opens the opening portion 13. Therefore, the structure for selecting the opening / closing operation according to the situation can be reliably simplified, and can be easily designed according to the specifications.

Further, in the first opening / closing mode in which the door body 14 is rotated, when the traction drive unit 38 provided on the link member 24 pulls the endless belt 36 hung on the vehicle body side pulley 21 fixed to the vehicle body 12 side, the link member. 24 moves relative to the endless belt 36 so that it rotates about the first rotation shaft 19, and the door body 14 locked to the link member 24 rotates about the first rotation shaft 19. I will let you. When the traction drive unit 38 provided on the link member 24 pulls the endless belt 36 in the second opening / closing mode in which the door body 14 is moved in the posture when the opening 13 is closed, the link member 24 is moved to the endless belt. As a result of relative movement with respect to 36, the first pivot shaft 19 is pivoted, whereby the door body-side pulley 35 rotates with respect to the endless belt 36, and the door body 14 is moved together with the second body. It is rotated around the rotation shaft 33. As described above, the door main body 14 can be automatically opened / closed in both the first opening / closing mode and the second opening / closing mode by the traction drive unit 38 provided in the link member 24.
In addition to the above configuration, a support arm may be additionally provided between the vehicle body 12 and the door body 14 in order to support the door body 14.

  The door opening / closing structure according to the second embodiment of the present invention will be described below mainly with reference to the schematic diagram of FIG. 7 with a focus on differences from the first embodiment. Since FIG. 7 is a schematic diagram, illustration of a part of the configuration is omitted for convenience (see the first embodiment for the configuration not shown).

  The second embodiment is different from the first embodiment in that the diameter of the vehicle body side pulley 21 is smaller than the diameter of the door body side pulley 35. For example, the pulley ratio between the vehicle body side pulley 21 and the door body side pulley 35 is 1: 2.

  In the second embodiment, when the first opening / closing mode is selected, the door body 14 rotates about the first rotation shaft 19 as in the first embodiment. When is selected, an operation different from that of the first embodiment is performed.

  That is, when the control unit (not shown) determines that the second opening / closing mode is selected from the closed state, the control unit unlocks the door body 14 with respect to the link member 24 by the link side locking device 47 and the pulley side locking device 44 The door body 14 is locked with respect to the door body side pulley 35. In this state, the endless belt 36 is pulled by the traction drive unit 38 provided in the link member 24 so as to move the door body 14 side to the door body side pulley 35 side. Then, since the vehicle body side pulley 21 is fixed to the vehicle body 12 and the door main body side pulley 35 is fixed to the door main body 14, the door main body side pulley 35 and the door main body 14 are used as the second rotation shaft 33. The link member 24 rotates about the first rotation shaft 19 forward in the vehicle front-rear direction while being rotated. At this time, since the door main body side pulley 35 has a larger diameter than the vehicle body side pulley 21 fixed to the vehicle body 12 side, the second rotation shaft 33 is centered with a small rotation amount relative to the rotation amount of the link member 24. It rotates around the first rotation shaft 19 while rotating to the center. As a result, the door main body 14 locked to the door main body side pulley 35 changes its posture so that the rear side in the vehicle front-rear direction is positioned on the outer side in the vehicle width direction from the front side as the opening angle increases. Then, the opening 13 is opened by moving in an arc shape around the first rotation shaft 19.

  On the other hand, when the door body 14 is closed from this state, the control unit causes the endless belt 36 to be pulled reversely by the pulling drive unit 38 provided in the link member 24. Then, the door main body 14 moves in an arc shape centering on the first rotation shaft 19 to the rear side in the vehicle front-rear direction while changing the posture opposite to the above, and closes the opening 13 to be in the above-described closed state. .

  According to the door opening / closing structure of the second embodiment as described above, by appropriately setting the pulley ratio between the vehicle body side pulley 21 and the door body side pulley 35, the door body 14 can be opened and closed in the second opening / closing mode. The posture can be changed.

  The door opening / closing structure of the third embodiment of the present invention will be described below mainly with reference to the schematic diagram of FIG. 8 with a focus on the differences from the first embodiment. Since FIG. 8 is a schematic diagram, a part of the configuration is omitted for convenience (see the first embodiment for a configuration not shown).

  The third embodiment is different from the first embodiment in that the diameter of the vehicle body side pulley 21 is larger than the diameter of the door body side pulley 35. For example, the pulley ratio between the vehicle body side pulley 21 and the door body side pulley 35 is 5: 3.

  In the third embodiment, when the first opening / closing mode is selected, the door body 14 rotates about the first rotation shaft 19 as in the first embodiment and the second embodiment. When the second opening / closing mode is selected, an operation different from the first embodiment and the second embodiment is performed.

  That is, when the control unit (not shown) determines that the second opening / closing mode has been selected from the closed state, the link-side lock device 47 unlocks the door body 14 with respect to the link member 24 and enables rotation, and the pulley side. The door main body 14 is locked with respect to the door main body side pulley 35 by the lock device 44. Then, in this state, the endless belt 36 is pulled by the traction drive unit 38 provided on the link member 24 so that the door main body 14 side is moved to the door main body side pulley 35 side with respect to the link member 24. Then, since the vehicle body side pulley 21 is fixed to the vehicle body 12 and the door main body side pulley 35 is fixed to the door main body 14, the door main body side pulley 35 and the door main body 14 are attached to the second rotation shaft 33. The link member 24 rotates about the first rotation shaft 19 forward in the vehicle front-rear direction while being rotated. At this time, since the door main body side pulley 35 has a smaller diameter than the vehicle body side pulley 21 fixed to the vehicle body 12 side, the door body side pulley 35 has a rotation amount larger than the rotation amount of the link member 24 around the second rotation shaft 33. It rotates around the first rotation shaft 19 while rotating. As a result, the door main body 14 locked to the door main body side pulley 35 changes its posture so that the front side in the vehicle front-rear direction is positioned on the outer side in the vehicle width direction from the rear side as the opening angle increases. The opening 13 is opened by moving in an arc shape centered on the first rotation shaft 19.

  On the other hand, when the door body 14 is closed from this state, the control unit causes the endless belt 36 to be pulled reversely by the pulling drive unit 38 provided in the link member 24. Then, the door main body 14 moves in a circular arc shape to the rear side in the vehicle front-rear direction while changing the posture in the opposite direction to the above, and closes the opening 13 to be in the above-described closed state.

  Even in the door opening and closing structure of the third embodiment as described above, the posture when the door body 14 is opened and closed in the second opening and closing mode by appropriately setting the pulley ratio between the vehicle body side pulley 21 and the door body side pulley 35. Changes can be made.
