And when reaching the protrusion position D2, the turning displacement roller Rv will escape | deviate the turning curved rail rr, and will change direction by almost 90 degrees, and will reach | attain the long straight rail groove | channel rs in the front-back direction X. Then, when the sliding area between the protruding position D2 and the fully open position D3 is reached, the slider 206 side of the turning end of the parallel link including the front arm 207 is positioned at the protruding position D2. It stops, and the linear rail groove sr on the rail side relatively slides with respect to the turning center roller Ro and the turning displacement roller.

In this way, in the protruding position D2, the turning displacement roller Rv is directed toward the fully open position D3 according to the direction when the roller is moving along the turning curved rail rr and the straight rail groove sr. The direction at the time of the roller stand movement is switched 90 degrees, and the driving resistance force p1 with respect to the direction of the fully open position D3 which the open / close drive mechanism 203 receives is largely switched. That is, the opening / closing drive mechanism 203 needs to keep the switching drive force relatively large in order to cope with the sudden increase in the driving resistance force in the later stage of turning. In addition, there is a problem that the driving force applied by the opening and closing drive mechanism 203 tends to cause the switching shock due to the sudden change in the driving resistance force in the switching from the late turning stage to the sliding initial stage.

In this way, when the rail on the door side reaches the protruding position D2, immediately after that, the turning displacement roller Rv shifts the moving direction by 90 degrees about the turning center roller Ro, and enters the turning curved rail rr. The roller moves along the copper rail, i.e., the parallel link side including the front arm 207 pivots relative to the rail 205 on the door side. In this case, since the opening / closing drive mechanism 203 switches that the rail 205 on the door side starts turning against the rail 205 after the sliding of the front arm 207 ends, In order to cope with the rapid change from the late sliding to the initial swing, it is necessary to keep the switching driving force F1 relatively large. In addition, there is a problem that a switching shock accompanying the driving force F1 applied by the opening and closing drive mechanism 203 is likely to occur due to the sudden change of the driving resistance force p1 in the switching.

When turning in the area turning in the range of (h), in the direction of the fully open position D3 of the rail 22 (left direction in FIG. 3) by rolling contact with the first driven roller Rv described later. It is formed to allow an increase in the sliding displacement of. That is, excessive generation of the driving resistance force p1 as described in FIG. 16 is prevented in advance, thereby preventing the driving force F1 from becoming excessively large.

In addition, as shown in FIG. 8, the rail groove outer side wall in the site which joins the harrail groove 3311 of the curved paper path sr is formed as the turning initial displacement tolerance part wb which is a concave curved wall. As described later, the swing initial displacement allowable portion wb is the second driven type described later when the rail 22 approaches the protruding position D2 from the fully open position D3 side with respect to the front arm 311. It is formed so that roller Rc may gradually increase the rotational displacement with respect to the rail 22 of the front arm 31 by roller contact. That is, the front arm 31 drives by the rapid 90 degree shift of direction of rotation to the initial stage through the protruding position D2 with respect to the rail 22 on the door side as described in FIG. The resistive force p1 suddenly changes and prevents the occurrence of the switching shock accompanying the driving force F1 applied by the open / close drive mechanism 203.

Next, the opening / closing drive mechanism 19 of the swing slide unit U disposed in the rear door 4 will be described.

As shown in FIG. 1, the opening-closing drive mechanism 19 is a rotational force of the motor 101 and the winding drum 46 which form the drive source of the rear door 4 through the protruding position D2 from the closed position D1. And a function of moving to the fully open position D3.

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 turning ends of the rear arm 32 and the front arm 31 are drawn into the vehicle interior, and the sliders of the turning 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 turning center roller Ro is connected to the turning center regulating wall wc, and the first driven roller Rv is placed on 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 turning displacement roller Rk roll-contacts to 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 pivoting end of the front arm 31 and the slider 24 are integrally turned to the outside of the vehicle, and the door can pivot to the protruding position D2 side. That is, the parallel link 16 and the slider 24 of the turning end can be rotated in the opening direction, and in conjunction with this, the door 4 can be rotated to the protruding position D2 side.

In this case, first, the turning center roller Ro is in contact with the turning center regulating wall wc in the turning areas of FIGS. 8 (b), 8 (c) and 12 (b). One driven roller Rv leaves the curved paper path sr, and the turning displacement roller Rk rolls and moves according to the open shift curved wall wrs. Subsequently, the first driven roller Rv abuts against the sliding initial displacement allowable portion wa, thereby preventing the rail 22 side from relatively shifting with respect to the front arm 31, and thus, FIG. 8 (d) to ( g), the sliding 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 turning center roller Ro is the turning center The increase in the sliding displacement away from the restricting wall wc, i.e., in the direction of the fully open position D3 of the rail 22 (left direction in FIG. 9) is allowed.

Subsequently, in the turning areas of FIGS. 8 (h), (i), and 13 (e), the turning 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 turning area before entering the protruding position D2, and even when the sliding area reaches the sliding area after passing through the protruding position D2, some turning displacement is allowed.

That is, when the turning center roller Ro comes into contact with the turning 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 rolls in contact with the sliding initial displacement allowance wa when in the swiveling area prior to protruding, it is possible to allow the rail to start sliding against the arm just before the end of swing of the arm and rail. It is possible to continuously switch smoothly from the turning of the rail to the sliding, to suppress the sudden increase in the driving resistance F1 with the switching from the late turning to the sliding initial stage, and to accompany the sudden change of the switching driving force. The occurrence of shock can also be reduced.

Moreover, 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 fully open position D3, FIG. As shown in FIG. 10, the turning center roller Ro and the 1st driven roller Rv slide smoothly along the railroad groove 3311, and the door support rail 22 (rear door 4) is moved. It can be moved to the fully open 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, from the sliding areas of Figs. 8 (i) and 13 (e), it reaches the starting area of the turning area of Fig. 8 (h). Then, the turning initial displacement allowance part wb gradually permits the turning displacement of the second driven roller Rc in the regions of FIGS. 8 (g) to (d), 13 (d) and (c), and FIG. 8. In the regions of (c) to (a), FIG. 12 (b) and (a), the turning center roller Ro approaches the turning center regulating wall wc. Then, with the pivot center roller Ro in contact with the pivot center regulating wall wc, the front arm 31 pivots about the axial support center line Lrf of the pivot center roller Ro, and the pivot 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 pivoting center regulating wall wc, the shift in the door closing direction of the rail 22 can be prevented, and the pivoting center roller Ro of the front arm 31 is prevented. The second driven roller Rc moves to the turning initial displacement allowable portion wb when the rail 22 fitted with the lower guide groove 3311 approaches the protruding position D2 from the fully open position D3 side. Because of the roll contact, it is possible to allow the starting of the turning of the front arm 31 relative to the rail 22 just before the sliding end of the rail 22 relative to the front arm 31 and the turning of the front arm 31. Can be switched smoothly continuously, and the sudden increase in driving resistance force p1 accompanying the switching from the sliding late stage to the initial turning position via the protruding position D2 can be prevented, and the switching driving force F1 can be prevented. 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 turning displacement roller Rk in contact with the opening shifting curved wall wrs is excluded, and the rest of the configuration is almost the same. Omit.

The door opening and closing device of FIG. 14 slid the door by the sliding amount J1 in advance between the door closing position D1 and the turning start from FIG. 14 (1) to (5), thereby reliably from the engaged state of the latch. The sliding resistance at the start of the rotation of the door is reduced, and then the swing 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 sliding initial displacement allowance part is provided when the front arm 31 and the rail 22 are in the turning area before the protruding position D2. Since the first driven roller Rv is in roller contact with wa, the sliding start of the rail relative to the arm can be permitted just before the end of the swing of the arm and the rail, and the transition from the swing of the rail to the sliding is continuous. It can be carried out smoothly, it is possible to suppress the sudden increase in the dynamic resistance F1 accompanying the switching from the late turning stage to the sliding initial stage, and to reduce the occurrence of the shock accompanying the sudden change in the switching driving force.

Similarly, when the door is closed, the rail 22 which fitted the lower guide groove 3311 with respect to the turning center roller Ro of the front arm 31 moves from the fully open position D3 side to the protruding position D2. Since the second driven roller Rc rolls in contact with the turning initial displacement allowance wb when approaching, the front of the rail 22 immediately before the sliding end of the rail 22 with respect to the front arm 31. It is possible to allow the arm 31 to start swinging, to switch smoothly to the swing of the front arm 31 in succession, and to switch to the beginning of swing through the protruding position D2 from the sliding late stage. 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.
