That is, the opening / closing drive mechanism 19 is wound around the motor 101 and the motor 101 disposed inside the rear door 4 so as to be rewound to be wound as shown in FIGS. 1 and 9 to 11. The drive source M which consists of the drum 46, the open cable 49 and the closed cable 51 which are pulled freely by the winding drum 46, and the front end of the door support rail 22 which winds the open cable 49. End pulley (Po1), end pulley (Pc1) at the rear end of the door support rail (22) winding the closing cable (51), the first pulley (23f) in front of the slider (24), and the front arm (31). 2nd pulley Po2 (front intermediate pulley) on the upper side, the cable end Poe supported by the lateral flange part 15a and connecting the anchor part of the open cable 49, and the rear side of the slider 24 The first pulley 23r, the second pulley Pc2 (rear middle pulley) on the rear arm 32, and the lower flange 53d of the U-shaped fastening bracket 53 (see FIG. 3) are supported and closed cable ( 51) cherry tree And a connecting portion cable end (Pce).

Next, the operation of the rear door 4 will be described.

It is assumed that the rear door 4 is held in the closed position D1 before the controller 30 (see Fig. 9) receives the door opening command. At that time, non-energization was carried out with the front lock part J1 on the rear door 4 side, the power latch 6, 8 of the front lock part J2 and the rear lock part J3 maintaining the locked state. It is kept in a state.

In this case, as shown in Figs. 8A, 11, and 12A, the swing ends of the rear arm 32 and the front arm 31 are drawn into the vehicle inner side, and the sliders of the swing ends of both arms are inserted. Together with 24, the door support rail 22 supports the rear door 4 in the closed position (see FIG. 1) D1.

In this case, as shown in Fig. 8 (a), the swing center roller Ro is connected to the swing center restriction wall wc, and the first driven roller Rv is connected to the end wall wst of the curved paper path sr. By contacting, the shift | offset | difference to the front of a vehicle body (right direction in FIG. 8 (a), FIG. 11) of the rail 22 is regulated, and the rocking | displacement roller Rk makes a roll contact with the open shift curved wall wrs, The shift | offset | difference to the back of the door vehicle body (left direction in FIG. 8 (a), FIG. 11) of the rail 22 is regulated.

Next, when the controller 30 receives the door opening command, the lock part J1 on the front end of the rear door 4 in the closed position D1, the lock part J2 on the front end, and the rear end of the rear door 4 are closed via the wire harness 20. The output of unlocking is supplied to each of the power latches 6 and 8 of the lock portion J3.

When the controller 30 receives the door opening output based on the door opening command, as shown in Figs. 1 and 9, the controller 30 drives the winding drum 46 on the driving source M side to be shown as a thick solid line. The cable 49 is wound and the closed cable 51 is discharged. At this time, as shown in FIGS. 7 and 9, the tension applied to the open cable 49 causes the cable end Poe (open cable fixing end) and the second pulley Po2 on the front arm 31 ( The front middle pulley) is narrowed, the swing end of the front arm 31 and the slider 24 are rocked to the outside of the vehicle integrally, and the door can swing to the protruding position D2 side. That is, the parallel link 16 and the slider 24 of the swing end thereof can be swung in the opening direction, and the door 4 can be swung to the protruding position D2 side in conjunction with this.

In this case, first, in the swinging zones of FIGS. 8 (b), (c), and 12 (b), the first step on the front arm 31 is made while the swinging center roller Ro is in contact with the swinging center restricting wall wc. One driven roller Rv leaves the curved paper path sr, and the oscillation displacement roller Rk rolls and moves along the open shift curved wall wrs. Subsequently, the first driven roller Rv abuts against the slide initial displacement allowable portion wa to prevent the rail 22 side from being relatively shifted relative to the front arm 31, and thus, FIGS. 8 (d) to ( g), the slide initial displacement allowance wa gradually permits forward movement of the first driven roller Rv in the regions of FIGS. 12, 13 (b) and (d), and the pivot center roller Ro is the pivot center It is gradually allowed to increase the slide displacement away from the restricting wall wc, i.e., in the direction of the deployment direction position D3 of the rail 22 (left direction in FIG. 9).

Subsequently, in the swinging zones of FIGS. 8 (h), (i) and 13 (e), the swing center roller Ro and the first driven roller Rv together reach the harle groove 3311 and are relative to the rail. Is starting to move back and forth. That is, the sliding displacement starts in the swinging region before entering the protruding position D2, and even when the sliding region reaches the sliding region after passing through the protruding position D2, some swinging displacement is allowed.

That is, when the swing center roller Ro comes into contact with the swing center regulating wall wc, it is possible to prevent the rail from shifting in the door closing direction, and the front arm 31 and the rail 22 are located near the protruding position. Since the first driven roller Rv is in roll contact with the slide initial displacement allowance wa when in the swing zone before the protrusion, it is possible to allow the rail to start running against the arm just before the end of the swing of the arm and rail. It is possible to smoothly switch the runway from the swing of the rail to the runway, and to abruptly increase the sudden drive resistance F1 with the change from the late swing to the start of the slide, and to abruptly change the switching drive force. The occurrence of shock can also be reduced.

In addition, when the opening / closing drive mechanism 19 of the swing slide unit U drives, and the door support rail 22 side (rear door 4 side) slides back toward the deployment direction position D3, FIG. As shown in FIG. 10, the swinging center roller Ro and the first driven roller Rv slide smoothly along the harle groove 3311, and the door support rail 22 (rear door 4) is moved. It can be moved to the deployment direction position D3.

On the other hand, upon receiving the door closing instruction, the controller 30 outputs the door closing output to the motor 45 based on this, and drives the winding drum 46 to wind the closing cable 51 shown in a thick solid line, It is possible to release the open cable 49 shown in bold solid lines. At this time, the space | interval of the end pulley Pc1 of the rear end of the door support rail 22 which winds up the closing cable 51, and the 1st pulley 23r of the rear side of the slider 24 becomes narrow, and is shown in FIG. The front and rear arms 31 and 32 are returned to the protruding position D2.

In this case, first, the slide station of Figs. 8 (i) and 13 (e) reaches the starting station of the swinging station of Fig. 8 (h). Then, in the regions of FIGS. 8 (g) to (d), 13 (d) and (c), the swing initial displacement allowance wb gradually allows the swing displacement of the second driven roller Rc, and FIG. 8. In the regions of (c) to (a), FIGS. 12 (b) and (a), the swing center roller Ro approaches the swing center restricting wall wc. Then, the front arm 31 oscillates around the center of gravity Lrf of the oscillation center roller Ro while the oscillation center roller Ro is in contact with the oscillation center restriction wall wc, and the oscillation displacement roller ( Rk moves along the open shift curved wall wrs, and the front arm 31 reaches the closed position D1 as shown in FIG. 11 without deviating from the front-back direction.

In this way, when the pivoting center roller Ro abuts against the swinging center regulating wall wc, the shift in the door closing direction of the rail 22 can be prevented, and the swinging center roller Ro of the front arm 31 is prevented. The second driven roller Rc moves to the swing initial displacement allowance wb when the rail 22 fitted with the lower guide groove 3311 approaches the projected position D2 from the deployed position D3 side. Because of the roller contact, it is possible to allow the start of the swinging of the front arm 31 relative to the rail 22 just before the end of the slide of the rail 22 relative to the front arm 31 and the swinging of the front arm 31. It is possible to smoothly switch to, and it is possible to prevent the sudden increase in the driving resistance force p1 associated with the transition from the end of the slide to the initial swing of the swing via the protruding position D2, and the switching drive force F1. The occurrence of shock with sudden change of) can also be reduced.

In this manner, when the rear door 4 closes the rear hatch 3, the controller 30 subsequently closes the door by a position sensor not shown that the rear door 4 has reached the closed position D1. Receive a signal. In response, the controller 30 connects the wire harness 20 to each power latch (not shown) of the front lock part J1, the front lock part J2, and the rear lock part J3 of the rear door 4. The lock output is issued through the < RTI ID = 0.0 >), locks the rear door 4 to the rear lifting door 3, and the lock signal is input to the controller 30.

In the above-mentioned point, in the opening / closing drive mechanism 19 of the swing slide unit U which the door opening / closing apparatus of FIG. 1 employ | adopted, the motor which forms the drive source M which winds up and closes the open / close cables 49 and 51, and discharges. 101 and the winding drum 46 are accommodated in the door, and the cable ends Poe and Pce of the opening-closing drive mechanism 19 are attached to the base member 15 of the vehicle body side. However, the configuration is not limited to this, but the inverse configuration of connecting a pair of cable ends of the opening / closing cable of the opening / closing drive mechanism to the front and rear ends of the rails in the door (not shown) and mounting the motor and the winding drum to the base frame on the vehicle body side A door opening and closing device can be adopted. Also in this case, the same effect as the door opening and closing apparatus of FIG. 1 can be obtained.

14, the opening and closing apparatus of the swing slide door as another Example of this invention is shown. Compared with the opening and closing device of the swing slide door of FIG. 1, the opening and closing device differs in that the swing displacement roller Rk in contact with the opening shifted curved wall wrs is excluded, and the rest of the configuration is almost the same. Omit.

The door opening and closing device in FIG. 14 slides the door by the sliding amount J1 in advance between the door closing position D1 and the swing start from FIG. 14 (1) to (5), thereby reliably from the engaged state of the latch. Off, the sliding resistance at the start of the rotation of the door is reduced, and then the swinging displacement is performed between FIGS. 14 (6) to (12). In this area, the same behavior as the opening and closing device of the swing slide door of FIG. 1 is performed, and the slide initial displacement allowance part is provided when the front arm 31 and the rail 22 are in the swinging zone before the protrusion position D2. Since the first driven roller Rv is in roller contact with wa, the slide start of the rail relative to the arm can be allowed just before the end of the swing of the arm and the rail, and the transition from the swing of the rail to the runway is continuously It can perform smoothly, and can suppress the sudden increase of the dynamic resistance F1 accompanying the switch from the late swing | movement to the slide initial stage, and can also generate | occur | produce the shock accompanying a sudden change of switching drive force.

Similarly, when the door is closed, the rail 22 in which the lower guide groove 3311 is fitted to the swing center roller Ro of the front arm 31 is moved from the deployment direction position D3 to the protruding position D2. Since the second driven roller Rc rolls in contact with the swing initial displacement allowance wb when approaching, the front of the rail 22 immediately before the end of the slide of the rail 22 relative to the front arm 31. It is possible to allow the arm 31 to start swinging, to smoothly switch the swinging of the front arm 31 to the swing, and to switch to the swinging initial position via the protruding position D2 from the end of the slide. Sudden increase of the driving resistance force p1 can be prevented, and generation | occurrence | production of the shock accompanying the sudden change of the switching drive force F1 can also be reduced.
