Description

  The present invention relates to an opening / closing device for a swing slide door that opens and closes a swing slide door that opens and closes an entrance / exit provided on a side wall of a vehicle.

The swing slide door installed in the vehicle swings so as to protrude rearward and outward from the closed position where the entrance / exit is closed, and slides further rearward from the swing position to reach the fully open position where the entrance / exit is fully opened. Can do. Such a swing slide door is movably supported on the vehicle body side by a swing slide unit using a parallel link capable of regulating the movement position of the door.
An example of a door using such a swing slide unit is disclosed in Japanese Patent Laid-Open No. 10-175444 (Patent Document 1) and Japanese Patent Laid-Open No. 2007-196925 (Patent Document 2).

  The swing slide door disclosed in Patent Document 1 is configured to be manually opened and closed, and the swing slide door disclosed in Patent Document 2 is configured to be opened and closed by an opening / closing drive mechanism including a motor.

  Here, for example, in the case of a swing slide unit RU that is opened and closed by an opening and closing drive mechanism as shown in FIG. 15, the parallel link 200, a support arm 201 that supports a door load, and an opening and closing drive mechanism 203 that swings them are provided. . The parallel link 200 includes a pair of front and rear arms 207 and 208 whose front and rear pivot ends are connected to the vehicle body side bracket 204 and whose front and rear sliding ends are connected to a slider 206 fitted to the rail 205 on the door 204 side. The opening / closing drive mechanism 203 includes a motor 209 supported by the vehicle body side bracket 204, a winding drum 210 driven by the motor 209, and an open cable 211 and a closed cable connected to the winding drum 210 so as to be rewound and rewound. 212, a plurality of pulleys 213 for winding the open cable 211, a front cable stopper 214 on the door 204 side, a rear cable stopper 216 on the door side, and a plurality of pulleys 215 for winding the opening / closing operation cables 211, 212 Is provided.

  Here, when the winding drum 210 winds the open cable 211 when the door 204 is in the closed position D1, first, the front arm 207 on the parallel link protrudes by the tension applied to the plurality of pulleys 213 toward the protruding position D2. Then, the slider 206 fitted to the rail 205 in the door 204 protrudes and reaches the position D2. Further, when the open cable 211 is wound, the front cable stopper 214 receives tension in the opening direction (left side in FIG. 15), so that the rail 205 on the door side is rearward with respect to the slider 206 that has stopped swinging at the protruding position D2. The door 204 moves to the open position (fully open position) D3.

  Conversely, when the winding drum 210 winds the closed cable 212 when the door 204 is in the fully open position D3, the rear cable stopper 216 receives tension in the closing direction (right side in FIG. 15), and the slider 206 is The door 204 and the rail 205 move toward the forward protruding position D2, and the sliding of the door-side rail 205 with respect to the slider 206 stops at the protruding position D2. Further, the winding of the closed cable 212 causes the parallel link to swing due to the tension applied to the plurality of pulleys 213 on the front arm 207 of the parallel link, and the rail 205 on the door side swings together with the slider 206 from the protruding position D2 to the closed position D1 side. Then, the door 204 reaches the closed position D1.

Thus, the slider 206 pivotally supported by the pivot end of the parallel link via the pivot shaft swings together with the rail 205, and swings between the closed position D1 and the protruding position D2, and at that time, with respect to the slider 206 When the door-side rail 205 is relatively slidably displaced, it deviates from the trajectory. In order to prevent this, as shown in FIG. 16, a swinging center roller Ro is pivotally supported on the front arm 207 via a front pivot shaft b1, and is displaced by a predetermined amount from the swinging center roller Ro. A roller Rv is pivotally supported.
Here, the swinging center roller Ro pivotally supported by the front pivot shaft b1 contacts the swing center regulating wall wo formed on the rail 205 side, and the swing displacement roller Rv is moved along the swing curved rail groove rr. By moving, it is possible to prevent the door-side rail 205 from shifting in the door closing direction or the door opening direction, which is the vehicle body front-rear direction X, when swinging between the closed position D1 and the protruding position D2. The trajectory at the time of displacement is regulated.

JP 2003-320964 A JP 2007-196925 A

  By the way, as shown in FIG. 16, at the time of swinging between the closed position D1 and the protruding position D2, the front arm 207 side swings relative to the door-side rail 205 around the swing center roller Ro. Until the protruding position D2 is reached, the peristaltic displacement roller Rv moves about the swing center roller Ro along the peristaltic curved rail rr. When the protrusion position D2 is reached, the peristaltic displacement roller Rv leaves the peristaltic curved rail rr, changes direction by approximately 90 degrees, and reaches the straight rail groove sr that is long in the front-rear 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 sliding end of the parallel link including the front arm 207 stops at the protruding position D2, and is relatively straight on the rail side. The rail groove sr slides relative to the swing center roller Ro and the peristaltic displacement roller.

  In this way, at the protruding position D2, the peristaltic displacement roller Rv has a direction when the roller moves along the peristaltic curved rail rr and a direction when the roller moves toward the fully open position D3 along the straight rail groove sr. The drive resistance force p1 in the direction of the fully open position D3 received by the opening / closing drive mechanism 203 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 drive resistance force in the later stage of the swing. Moreover, there is a problem that the driving force applied by the opening / closing driving mechanism 203 is likely to cause a switching shock due to a sudden change in the driving resistance force in the switching from the late stage of the swing to the early stage of sliding.

Conversely, it is assumed that the swing center roller Ro and the peristaltic displacement roller Rv slide relatively along the straight rail groove sr on the rail 205 side and move from the fully open position D3 toward the closed position D1.
In this case, when it protrudes in the latter half of sliding and reaches the position D2, the swing center roller Ro comes into contact with the swing center regulating wall wo, and the swing displacement roller Rv rolls along the swing curve rail rr around the swing center roller Ro. The parallel link side including the front arm 207 swings relative to the door-side rail 205.

  As described above, when the door-side rail protrudes and reaches the position D2, the peristaltic displacement roller Rv enters the peristaltic curved rail rr by switching the moving direction by 90 degrees around the same swinging central roller Ro and along the rail. The roller moves, that is, the parallel link side including the front arm 207 swings relative to the rail 205 on the door side. In this case, the opening / closing drive mechanism 203 performs switching so that the arm 207 side starts to swing with respect to the rail 205 after the door-side rail 205 has finished sliding with respect to the front arm 207. In order to cope with the switching, it is necessary to keep the switching driving force F1 relatively large. Moreover, there is a problem that a switching shock accompanying the driving force F1 applied by the opening / closing driving mechanism 203 is likely to occur due to a sudden change in the driving resistance force p1 during switching.

  The present invention has been made on the basis of the problems as described above, and the object of the present invention is that the slider supported on the parallel link side and the door-side rail are relatively slid and held on the rail side of the door.

As will be described later, the sliding initial displacement allowable portion wa swings in the protruding front swing region D2bf (the range of (b) to (h) in FIG. 8) in the vicinity of the position D2 where the front arm 31 and the rail 22 protrude. When sliding in a region), an increase in sliding displacement in the direction of the fully open position D3 of the rail 22 (leftward in FIG. 3) is gradually allowed by roller contact with a first driven roller Rv described later. Is formed. That is, the generation of an excessive driving resistance force p1 as described with reference to FIG. 16 is prevented in advance, and the driving force F1 is prevented from becoming excessively large.

  Furthermore, as shown in FIG. 8, the rail groove outer wall at the portion where it joins the lower rail groove 3311 of the curved branch sr is formed as a swing initial displacement allowing portion wb that is a concave curved wall. As will be described later, when the rail 22 protrudes from the fully open position D3 side and approaches the position D2, the swinging initial displacement allowance portion wb is contacted by a second driven roller Rc described later. The front arm 31 is formed so as to gradually allow an increase in peristaltic displacement relative to the rail 22. That is, as described with reference to FIG. 16, the front arm 31 protrudes from the door-side rail 22 from the latter half of the sliding, and the driving resistance force p1 is changed by the sudden change of the moving direction of 90 degrees from the position D2 to the initial stage of the swing. Is suddenly changed to prevent a switching shock associated with the driving force F1 applied by the opening / closing drive mechanism 203.

Provided with over Li), a cable end Pce which is connected to the anchor portion of the support in the lower flange 53d closing cable 51 of the U-shaped fastening bracket 53 (see FIG. 3), the.

Next, the operation of the rear door 4 will be described.
It is assumed that the rear door 4 is held at the closed position D1 before the controller 30 (see FIG. 9) receives the door opening command. At that time, the power latches 6 and 8 of the front end upper lock portion J1, the front end lower lock portion J2 and the rear end lock portion J3 on the rear door 4 side are held in a non-energized state while holding the locked state.
In this case, as shown in FIGS. 8 (a), 11 and 12 (a), the swinging ends of the rear arm 32 and the front arm 31 are drawn into the vehicle interior, and the door is supported together with the slider 24 at the swinging end of both arms. The rail 22 holds the rear door 4 in the closed position (see FIG. 1) D1.

In this case, as shown in FIG. 8A, the swing center roller Ro contacts the swing center regulating wall wc, and the first driven roller Rv contacts the end wall wst of the curved branch sr, whereby the vehicle body of the rail 22 is obtained. The forward displacement (FIG. 8 (a), rightward in FIG. 11) is restricted, and the peristaltic displacement roller Rk comes into contact with the open displacement curved wall wrs so that the rear side of the door 22 of the rail 22 (FIG. 8 (a)). , The shift to the left in FIG. 11 is regulated.
Next, when the controller 30 receives a door opening command, the power latches 6 and 8 of the front end upper lock portion J1, the front end lower lock portion J2, and the rear end lock portion J3 of the rear door 4 at the closed position D1 are connected via the wire harness 20. The lock release output is issued.

  Further, 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 drive source M side to wind the open cable 49 indicated by a thick solid line. The closed cable 51 is discharged. At this time, as shown in FIGS. 7 and 9, due to the tension applied to the open cable 49, the gap between the cable end Poe (open cable fixed end) and the second pulley Po2 (front intermediate pulley) on the front arm 31 is narrowed. The sliding end 31 and the slider 24 integrally swing to the outside of the vehicle, and the door protrudes and can swing to the position D2 side. That is, the parallel link 16 and the slider 24 at the sliding end thereof are slid in the opening direction, and the door 4 can be projected and slid to the position D2 side in conjunction with this.

  In this case, first, in the swing region shown in FIGS. 8B, 8C, and 12B, the swing center roller Ro remains in contact with the swing center regulating wall wc, and the first on the front arm 31 is moved. The driven roller Rv leaves the curved branch sr, and the peristaltic displacement roller Rk rolls along the open deviation curved wall wrs. Next, the first driven roller Rv is brought into contact with the sliding initial displacement allowable portion wa to prevent the rail 22 side from being relatively displaced with respect to the front arm 31, and eventually, FIGS. 8D to 8G and FIG. In the regions 12, 13 (b), (d), the sliding initial displacement allowing portion wa gradually allows the first driven roller Rv to move forward, and the swinging center roller Ro is separated from the swinging center regulating wall wc. The sliding displacement is gradually allowed to increase in the direction of the fully open position D3 of the rail 22 (leftward in FIG. 9).

  8 (h), (i), and FIG. 13 (e), the swing center roller Ro and the first driven roller Rv both reach the lower rail groove 3311 and move forward and backward relative to the rail. The movement has started. That is, the sliding displacement is started in the swing region before entering the protruding position D2, and the partial displacement is allowed even when reaching the sliding region after passing through the protruding position D2.

  That is, when the swing center roller Ro abuts on the swing center regulating wall wc, the rail can be prevented from shifting in the door closing direction, and when the front arm 31 and the rail 22 are in the projecting front swing region in the vicinity of the projecting position. Since the first driven roller Rv comes into roller contact with the sliding initial displacement allowable portion wa, it is possible to allow the rail to start sliding with respect to the arm just before the end of the swing of the arm and the rail, and the switching from the rail swing to the sliding is continuously performed. It is possible to suppress the sudden increase in the driving resistance force F1 associated with the switching from the latter stage of the swing to the early stage of sliding, and to reduce the occurrence of shock due to the sudden change in the switching driving force.

  Further, when the opening / closing drive mechanism 19 of the swing slide unit U is driven and the door support rail 22 side (rear door 4 side) slides rearward toward the fully open position D3, as shown in FIG. 10, the swing center roller Ro Both the first driven roller Rv slide smoothly along the lower rail groove 3311, and the door support rail 22 (rear door 4) can be moved to the fully open position D3.

On the other hand, when receiving the door closing command, the controller 30 outputs a door closing output to the motor 45 based on this, drives the winding drum 46 to wind up the closed cable 51 indicated by a thick solid line, and opens the opening indicated by the thick solid line. The cable 49 can be discharged. At this time, the distance between the end pulley Pc1 at the rear end of the door support rail 22 around which the closed cable 51 is wound and the first pulley 23r on the rear side of the slider 24 is narrowed, and the front and rear arms 31 are moved to the protruding position D2 shown in FIG. , 32 returns.
In this case, first, the peristaltic region start region of FIG. 8 (h) is reached from the sliding region of FIG. 8 (i) and FIG. 13 (e). Soon, the swing initial displacement allowing portion wb gradually allows the second driven roller Rc to move in the regions shown in FIGS. 8G to 8D, 13D, and 13C. ) To (a) and FIGS. 12B and 12A, the swinging center roller Ro approaches the swinging center regulating wall wc. Then, with the swing center roller Ro in contact with the swing center regulating wall wc, the front arm 31 swings about the pivot center line Lrf of the swing center roller Ro, and the swing displacement roller Rk opens and curves. The roller moves along the wall wrs, and the front arm 31 reaches the closed position D1 as shown in FIG.

  As described above, the swing center roller Ro abuts against the swing center regulating wall wc to prevent the rail 22 from being displaced in the door closing direction, and the lower guide groove 3311 with respect to the swing center roller Ro of the front arm 31. Since the second driven roller Rc comes into roller contact with the swinging initial displacement allowance portion wb when the rail 22 fitted with the projection protrudes from the fully open position D3 side and approaches the position D2, the slide of the rail 22 with respect to the front arm 31 is almost finished. The front arm 31 can be allowed to start swinging with respect to the rail 22, and the front arm 31 can be switched to the swing continuously and smoothly. An increase in the resistance force p1 can be prevented, and the occurrence of a shock due to a sudden change in the switching drive force F1 can also be reduced.

In this way, when the rear door 4 closes the rear entrance 3, the controller 30 thereafter receives a door closing signal from a position sensor (not shown) that the rear door 4 has reached the closing position D <b> 1. In response to this, the controller 30 issues a lock output via the wire harness 20 to each power latch (not shown) of the front end upper lock portion J1, the front end lower lock portion J2, and the rear end lock portion J3 of the rear door 4. Is locked to the rear entrance 3 and a lock signal is input to the controller 30.
As described above, in the opening / closing drive mechanism 19 of the swing slide unit U employed in the door opening / closing device of FIG. 1, the motor 101 and the winding drum 46 that constitute the driving source M that winds and discharges the opening / closing cables 49 and 51. Is housed in the door, and cable ends Poe and Pce of the opening / closing drive mechanism 19 are attached to the base member 15 on the vehicle body side. However, the present invention is not limited to this, and the pair of cable ends of the opening / closing cable of the opening / closing drive mechanism are connected to the front and rear ends of the rail in the door (not shown), and the motor and winding drum are mounted on the vehicle body side frame. It is possible to adopt a door opening and closing device that takes the reverse configuration of doing. Also in this case, the same effect as the door opening and closing apparatus of FIG. 1 can be obtained.

In addition, in FIG. 14, the opening / closing apparatus of the swing slide door as another Example of this invention was shown. This opening / closing device is different from the opening / closing device of the swing slide door of FIG. 1 in that the peristaltic displacement roller Rk that abuts against the opening deviation curved wall wrs is excluded, and the other configurations are almost the same. The duplicate description is omitted.
The door opening and closing device of FIG. 14 slides the door by a sliding amount J1 in advance between FIGS. 14 (1) to (5) from the door closing position D1 to the start of swinging, and reliably releases it from the meshing state of the latch. The sliding resistance at the start of the rotation of the door is reduced, and the peristaltic displacement is performed between FIGS. 14 (6) to (12). In this region, the same behavior as that of the swing slide door opening / closing device of FIG. 1 is performed. When the front arm 31 and the rail 22 are in the protruding front peristaltic region in the vicinity of the protruding position D2, the sliding initial displacement allowable portion wa Since the driven roller Rv comes into contact with the roller, the rail can start to slide relative to the arm just before the end of the swing of the arm and the rail, and the switching from the swing of the rail to the slide can be performed smoothly and continuously. An abrupt increase in the driving resistance force F1 associated with the switching to the initial stage can be suppressed, and the occurrence of a shock associated with a sudden change in the switching driving force can also be reduced.

  Similarly, when the door is closed, when the rail 22 fitted with the lower guide groove 3311 to the swing center roller Ro of the front arm 31 protrudes from the fully open position D3 side and approaches the position D2, the second driven roller Rc is moved. Since the roller is in contact with the swinging initial displacement allowable portion wb, the front arm 31 can be allowed to start swinging with respect to the rail 22 just before the end of sliding of the rail 22 with respect to the front arm 31, and the switching of the front arm 31 to the swing is continuously performed. It is possible to perform smoothly, to prevent a sudden increase in the driving resistance force p1 associated with the switching to the initial stage of the swing through the protruding position D2 from the latter half of the sliding, and to reduce the occurrence of a shock due to a sudden change in the switching driving force F1. it can.
