[Operation of plug door device]
Next, the operation of the plug door device 1 will be described. As shown in FIGS. 1 to 5, when the door 104 is in the closed position, the shaft portion 14 is viewed from above, the first notch 24 a of the first link 24 and the second notch of the second link 25. It engages with both of the portions 25a (see FIG. 7). That is, the shaft portion 14 is located in the notches (24a, 25a).

  When the door 104 is in the closed position, as shown in FIGS. 6, 13, and 14, in the lock mechanism 17, the roller 42 is in contact with the first surface 36 a of the lock fixing portion 36. For this reason, the movement of the slide base 12 to the outside in the vehicle width direction is restricted via the carrier 20c of the lock mechanism 17 and the planetary gear mechanism 20. Thereby, the plug operation to the outside in the vehicle width direction by the plug mechanism is restricted, and the door 104 is locked so that the movement is restricted.

  When the direct drive type brushless electric motor 21 of the door drive mechanism 13 is driven from the above-mentioned closed position, the sun gear 20a of the planetary gear mechanism 20 starts rotating, and the planetary gear 20b around the sun gear 20a is rotated. Revolving around the sun gear 20a is started while meshing with the ring gear 20d. Then, due to the swing of the carrier 20c accompanying the revolution of the planetary gear 20b, the output roller 22a moves in the long hole 43a in the direction indicated by the two-dot chain line arrow I in FIG. As a result, the transmission member 40 moves together with the output roller 22a in parallel with the opening direction in the longitudinal direction of the vehicle, and the slide block 41 also moves on the slide rail 39 in parallel with the opening direction.

  As a result, the roller 42 that has been in contact with the first surface 36a moves to a position that is out of the first surface 36a. In FIG. 13 and FIG. 14, the position of the roller 42 that has moved to the position deviated from the first surface 36a is shown as a two-dot chain line roller 42a. As a result, the locked state of the door 104 by the lock mechanism 17 is released, and the plug mechanism can be plugged outward in the vehicle width direction.

  As described above, when the transition to the state in which the plug operation to the outside in the vehicle width direction is possible, the drive of the brushless electric motor 21 of the door drive mechanism 13 is further continued. Thereby, the driving force output to the driving pulley 13b via the ring gear 20d is further transmitted to the shaft portion 14 via the driving belt 13d and the connecting portion 19. For this reason, the shaft portion 14 urges the second link 25 in the same direction in an attempt to move in the opening direction.

  Here, as shown in FIG. 7, the rotation of the second link 25 relative to the first link 24 (rotation in the clockwise direction around the second rotation shaft 27 when viewed from above) The roller 28 is regulated at a position where the roller 28 contacts the inclined surface 23 a of the roller guide 23. Therefore, the second link 25 hardly rotates with respect to the first link 24, and the second link 25 is rotated to the first link 24 via the second rotation shaft 27 (rotating power about the first rotation shaft 26 (upward). (Turning power in the clockwise direction when viewed from the side). As a result, the guide roller 28 moves along the slope 23a, and the first link 24 rotates about the first rotation shaft 26 in the direction indicated by the arrow H in the figure.

  While the first link 24 rotates in the clockwise direction when viewed from above, the guide roller 28 of the second link 25 moves along the inclined surface 23 a of the roller guide 23. At this time, since the second link 25 is attracted to the slope 23a side by the helical spring 30, the guide roller 28 does not leave the slope 23a. Further, when the guide roller 28 is moving along the inclined surface 23 a, the first cutout portion 24 a of the first link 24 and the second cutout portion 25 a of the second link 25 travel around the shaft portion 14. The enclosed state is maintained.

  When the shaft portion 14 further moves in the opening direction from the above state, the contact position between the guide roller 28 and the roller guide 23 shifts from the inclined surface 23a to the curved surface 23b. As a result, the guide roller 28 is pulled inward in the vehicle width direction along the curved surface 23b, and the second link 25 is viewed from above with respect to the first link 24 around the second rotation shaft 27. Relative rotation in clockwise direction. That is, as shown in FIG. 11, the restraint of the shaft portion 14 by the second link 25 is released. At this time, the rotation of the first link 24 in the arrow H direction is restricted by the first link 24 coming into contact with the stopper 44 fixed to the roller guide 23.

  As described above, when the door 104 opens, the guide portion 15 rotates while contacting the shaft portion 14 so that the shaft portion 14 moves in one of the vehicle width directions (opening direction). It is configured as a guiding mechanism.

  In the present embodiment, the first link 24 is arranged so that the first cutout portion 24a is located on the outer side in the vehicle width direction with respect to the position of the first rotation shaft 26 when the door 104 is in the closed position. ing. When the door 104 is in the closed position, the guide roller 28 is positioned on the outer side in the vehicle width direction from the center of the shaft portion 14, and the second rotating shaft 27 is in the vehicle width direction from the center of the shaft portion 14. The 2nd link 25 is arrange | positioned so that it may be located inside. With such a configuration, the guide portion 15 is configured so that the urging force from the shaft portion 14 can be efficiently used for turning the first link 24.

  Moreover, when the 1st link 24 rotates as mentioned above, the force which faces a vehicle width direction outer side acts with respect to the axial part 14. FIG. Therefore, a force directed outward in the vehicle width direction also acts on the door drive mechanism 13 coupled to the shaft portion 14 via the coupling portion 19, and the vehicle is also applied to the slide base 12 on which the door drive mechanism 13 is installed. A force directed outward in the width direction acts.

  As described above, the door drive mechanism 13 and the slide base 12 are guided by the slide support portion 11b in the fixed base 11 and moved outward in the vehicle width direction. As a result, a plug operation in which the door 104 moves outward in the vehicle width direction is performed. Then, when the plug operation is performed, the door 104 can be moved in the opening direction.

  Further, when the plug operation to the outside in the vehicle width direction by the plug mechanism is completed, the slide contact portion 38 installed on the slide rail 39 fixed to the slide base 12 also moves outward in the vehicle width direction together with the slide base 12. It will be. Accordingly, the roller 42 located at the position shown as the two-dot chain line roller 42a in FIG. 14 moves to the position shown as the one-dot chain line roller 42b. And the roller 42 (42b) will transfer to the state contact | abutted to the 2nd surface 36b of the lock fixing | fixed part 36. FIG.

  The lock output unit 22 connected to the carrier 20c of the planetary gear mechanism 20 has a biasing means such as a spring for biasing the output roller 22a in the direction opposite to the direction indicated by the two-dot chain line arrow I in FIG. (Not shown) is provided. In a state where the roller 42 is in contact with the second surface 36b, the urging force of the urging means acts on the slide contact portion 38 via the output roller 22a and the transmission member 40, so that the roller 42 is in the second surface. The state pressed against 36b is maintained.

  In addition, in a state where the roller 42 is pressed against and in contact with the second surface 36b, a reaction force that balances the driving force input from the carrier 20c of the planetary gear mechanism 20 to the lock mechanism 17 is generated on the second surface 36b. Become. Thereby, the driving pulley 13b is rotationally driven by the driving force input from the ring gear 20d of the planetary gear mechanism 20 to the driving pulley 13b.

  And with the rotation of the drive pulley 13b, the drive belt 13d is driven, and the support rail 16d and the pinion 16c in the double speed rail 16 move together with the connecting portion 19. Therefore, the upper rack 16a connected to the door 104 moves at a double speed relative to the pinion 16c with respect to the lower rack 16b fixed to the slide base 12. Thereby, the door 104 moves in the opening direction, and the opening operation of the door 104 is performed. During the movement of the door 104 in the opening direction, the shaft portion 14 does not receive a force in the vehicle width direction from the guide portion 15 and moves linearly in the opening direction together with the connecting portion 19.

  FIG. 15 is a schematic diagram as a plan view of the plug door device 1 shown in FIG. 3, and also shows the position of the door 104 where the opening operation has been performed. When the opening operation of the door 104 is completed, the door 104 moves to a position indicated by a two-dot chain line in FIG.

  On the other hand, when the door 104 is closed, an operation opposite to the opening operation of the door 104 described above is performed. That is, the direct drive type brushless electric motor 21 in the door drive mechanism 13 is driven, and the drive pulley 13b driven through the planetary gear mechanism 20 rotates in the opposite direction to that in the above opening operation. Thereby, the support rail 16d and the pinion 16c connected with the connection part 19 move to a reverse direction with the case of the above-mentioned opening operation | movement. Then, the upper rack 16a connected to the door 104 moves at a double speed relative to the pinion 16c with respect to the lower rack 16b fixed to the slide base 12. As a result, the door 104 moves in the closing direction, and the door 104 is closed. Further, the shaft part 14 moves linearly toward the guide part 15 in the closing direction.

  In the guide portion 15, when the door 104 is opened, the helical spring 30 acts on the second link 25 in the clockwise direction as viewed from above. That is, a pulling force is applied to the second link 25 from the helical spring 30 so that the guide roller 28 is located at a position in contact with the curved surface 23 b of the roller guide 23. In the present embodiment, the guide roller 28 is fitted in a recess having a semicircular arc shape that is substantially the same as the outer peripheral shape of the guide roller 28 on the curved surface 23b. Accordingly, the first link 24 and the second link 25 are stably held at predetermined positions. Specifically, the second link 25 is held at a position where the shaft portion 14 that has linearly moved in the closing direction can come into contact with the inner edge of the second cutout portion 25a. Moreover, the 1st link 24 is also hold | maintained in the position which can accommodate the axial part 14 which moved linearly in the closing direction in the 1st notch part 24a (refer FIG. 11).

  Accordingly, the shaft portion 14 abuts against the inner edge of the second cutout portion 25a of the second link 25 when the door 104 moves a predetermined amount in the closing direction from the fully open position (see FIG. 11). The two links 25 are energized. At this time, the second link 25 rotates counterclockwise when viewed from above about the second rotation shaft 27 against the force of the helical spring 30, so that the shaft portion 14 moves in the closing direction. Linear movement is not hindered. When the second link 25 rotates, the guide roller 28 moves along the curved surface 23 b of the roller guide 23. When the second link 25 is rotated, the first link 24 is held at a predetermined position or in the vicinity thereof with little rotation.

  Then, the shaft portion 14 moves in the closing direction to a position where it contacts the inner edge of the first cutout portion 24a of the first link 24, and urges the first link 24 in the closing direction. Thus, the first link 24 rotates counterclockwise as viewed from above about the first rotation shaft 26, and the shaft portion 14 is guided inward in the vehicle width direction.

At this time, the door 104 moves in the same manner as the shaft portion 14. That is, the door 104 is configured to move linearly in a position either et closing direction fully open, in the closed position near the unit, the process proceeds to the closed position is drawn in the vehicle width direction inside. Thereby, the plug operation to the inside in the vehicle width direction by the plug mechanism is completed.

  As described above, when the door 104 is closed, the guide portion 15 rotates while contacting the shaft portion 14 so that the shaft portion 14 moves to the other side (the closing direction) in the width direction of the vehicle. It is comprised as a mechanism which guides.

  Further, when the plug operation to the inside in the vehicle width direction by the plug mechanism is completed, the slide contact portion 38 installed on the slide rail 39 fixed to the slide base 12 also moves in the vehicle width direction together with the slide base 12. It will be. As a result, the roller 42 located at the position shown as the one-dot chain line roller 42b in FIG. 14 moves to the position shown as the two-dot chain line roller 42a.

  When the roller 42 moves as described above, the reaction force from the second surface 36b of the lock fixing portion 36 does not act on the roller 42. For this reason, due to the driving force input from the carrier 20c of the planetary gear mechanism 20 via the output roller 22a, the transmission member 40 moves in parallel with the closing direction in the front-rear direction of the vehicle, and the slide block 41 also moves on the slide rail 39. Move parallel to the closing direction.

  As described above, the roller 42 moves from the position shown as the two-dot chain line roller 42 a in FIG. 14 to the position where it abuts on the first surface 36 a of the lock fixing portion 36. Thereby, the locked state of the door 104 by the lock mechanism 17 is ensured, and the plug operation to the outside in the vehicle width direction by the plug mechanism cannot be performed.

  In addition, when the opening operation | movement of the door 104 mentioned above and closing operation | movement are performed, the rotation arm 18 (18a, 18b) provided in the upper part and the lower part of the entrance / exit 102 rotates, respectively. As a result, the movement of the door 104 in the vehicle width direction is also guided by the upper and lower rotary arms 18 (18a, 18b), and the door 104 is smoothly plugged.

[Effect of plug door device]
According to the plug door device 1 described above, the guide portion 15 abuts on the shaft portion 14 and rotates to guide the shaft portion 14 in the vehicle width direction. Therefore, the operation of the guide portion 15 is an operation that follows the movement of the door 104 in the vehicle width direction. Thereby, according to the movement state of the door 104 in the vehicle width direction, the space occupied by the guide portion 15 in the vehicle width direction can be further reduced. Thereby, the small plug door apparatus 1 which can perform an opening / closing operation | movement and a plug operation | movement with the door drive mechanism 13 which applies the force to the front-back direction of a vehicle with respect to the door 104 is realizable. Further, since the door drive mechanism 13 moves the door 104 in the longitudinal direction of the vehicle via the double speed rail 16 constituted by two racks (16a, 16b) and a pinion 16c, the operation stroke of the door drive mechanism 13 is doubled. Thus, the door 104 can be moved efficiently. For this reason, a further compact plug door device 1 can be realized in the longitudinal direction of the vehicle.

  According to the plug door device 1, the lock moving portion 37 contacts the lock fixing portion 36 fixed on the fixed base 11 side on the inner side in the vehicle width direction, so that the door 104 moves outward in the vehicle width direction when closed. Movement is restricted. For this reason, when the door 104 is closed, the door 104 is restrained so that it does not move more reliably and does not move outward in the vehicle width direction. Therefore, the door 104 can be locked without rattling when closed.

  Therefore, according to the present embodiment, it is possible to realize a small plug door device 1 that can perform an opening / closing operation and a plug operation by the door drive mechanism 13 that applies a force in the front-rear direction of the vehicle to the door 104. It is possible to provide a plug door device 1 that can lock the door 104 without rattling when closed.

  In addition, according to the plug door device 1, the driving force from the planetary gear mechanism 20 is transmitted to the slide contact portion 38 via the transmission member 40, so that the slide contact portion 38 performs a predetermined restriction on the slide rail 39. It slides along the formed direction and comes into contact with the lock fixing portion 36. For this reason, since the slide contact part 38 moves smoothly on the slide rail 39 by the driving force from the planetary gear mechanism 20, the necessity of setting the strength of the planetary gear mechanism 20 high can be suppressed. Thereby, the planetary gear mechanism 20 can be configured more compactly.

  Further, according to the plug door device 1, the slide contact portion 38 can move on the slide rail 39 by the slide block 41 while contacting the lock fixing portion 36 by the rotatable roller 42. For this reason, it is suppressed that the frictional force with the lock fixing part 36 prevents the movement of the slide contact part 38 on the slide rail 39, and the slide contact part 38 can move smoothly on the slide rail 39. it can.

  Further, according to the plug door device 1, the one door drive mechanism 13 that is installed on the slide base 12 and moves the one door 104 in the front-rear direction of the vehicle via the connecting portion 19 and the double speed rail 16 is provided with the brushless electric motor 21. Including a drive pulley 13b, a drive pulley 13b to which a drive force from the drive unit 13a is input, a driven pulley 13c, and a drive belt 13d that rotates the driven pulley 13c as the drive pulley 13b rotates. For this reason, the drive pulley 13b and the driven pulley 13c do not move during the operation of the door drive mechanism 13. Thereby, a part of door drive mechanism 13 does not protrude greatly with respect to the entrance 102 where the door 104 is installed. Therefore, the restriction of the installation space is greatly suppressed, and it can be easily applied to the one-way door 104.

  Further, according to the plug door device 1, the drive unit 13 a includes the direct drive brushless electric motor 21 and the planetary gear mechanism 20. Then, in the sun gear 20a, the carrier 20c, and the ring gear 20d of the planetary gear mechanism 20, the driving force of the brushless electric motor 21 is input to one of them, and the driving force from the other one is output to the driving pulley 13b and remains. The driving force from one is output to the lock mechanism 17. Therefore, the single drive-less brushless electric motor 21 can perform the opening / closing operation of the door 104, the plug operation, and the locking operation of the door 104 by the lock mechanism, thereby realizing a compact and efficient drive unit 13a. be able to.

  Further, according to the plug door device 1, when the door 104 is closed, the lock moving portion 37 contacts the first surface 36 a of the lock fixing portion 36 and the door 104 is locked. On the other hand, when the door 104 is opened and closed, the lock moving portion 37 and the second surface 36b of the lock fixing portion 36 come into contact with each other, and the force acting between the two is balanced, and the planetary gear mechanism 20 moves to the lock mechanism 17. The output of is fixed. The driving pulley 13b, the driven pulley 13c, and the driving belt 13d are operated by the driving force input from the planetary gear mechanism 20 to the driving pulley 13b, and the door 104 is opened and closed. For this reason, the drive force is distributed from the planetary gear mechanism 20 to the drive pulley 13b and the lock mechanism 17 by the lock fixing portion 36 provided with the first surface 36a and the second surface 36b orthogonal to each other. Therefore, a configuration in which the driving force is efficiently distributed to the drive pulley 13b and the lock mechanism 17 can be realized by a simple mechanism in which the lock fixing portion 36 is provided with the first surface 36a and the second surface 36b.

  FIG. 22 is a front view showing the link mechanism 64 and the link holding mechanism 65 together with the guide plate 43. As well shown in FIGS. 20 and 22, the link mechanism 64 is provided as a mechanism that can be deformed into a straight state and a bent state in a vertical plane. The link mechanism 64 is configured by connecting three links (64a, 64b, 64c) in series. The center link 64a is rotatably supported with respect to the guide plate 43 at the center by a connecting pin 67a. As in the first embodiment, the guide plate 43 is provided as a plate-like member fixed to the housing or the like of the drive unit 53a installed on the slide base 52. The guide plate 43 is formed with a long hole 43a in which the output roller 22a is disposed below the position where the connecting pin 67a is attached.

One end of the link 64c is rotatably connected to the other end of the central link 64a via a connecting pin 67c. A pin 67d is provided at the end of the link 64b opposite to the side connected to the link 64a. And the pin 67e is provided in the edge part on the opposite side to the side connected with the link 64a in the link 64c. The pins (67d, 67e) provided at the ends of the link mechanism 64 are loosely fitted into the long guide holes (43b, 43c) extending in the guide plate 43 in parallel with the longitudinal direction of the vehicle. Is inserted.

  Further, the central link 64a is provided with a portion projecting downward from an intermediate portion between the coupling pin 67a and the coupling pin 67b, and a position facing the long hole 43a by the edge of the projecting portion. A recess 68 that can be opened and contacted with the output roller 22a is formed. In the link mechanism 64, the link 64a that is in contact with the output roller 22a moving along the long hole 43a by the recess 68 rotates about the connecting pin 67a. As the link 64a rotates, the link (64b, 64c) in which the movement direction of the pin (67d, 67e) is regulated by the guide groove (43b, 43c) is the link 64a centering on the connection pin (67b, 67c). It rotates relative to. As a result, the link mechanism 64 is deformed from a straight state to a bent state.

  The link holding mechanism 65 includes a pair of engaging members (69a, 69b) and a pair of urging springs (70a, 70b). The pair of engaging members (69a, 69b) are disposed in the vicinity of both ends of the link mechanism 64 so as to be rotatable in a vertical plane symmetrically with respect to the link mechanism 64 (with respect to the connecting pin 67a). . Note that the engagement member 69a is rotatably supported with respect to the guide plate 43 via a rotation shaft 73a. Further, the engaging member 69b is rotatably supported with respect to the guide plate 43 via a rotating shaft 73b.

  Each engagement member (69a, 69b) is provided with a first engagement portion (71a, 71b) and a second engagement portion (72a, 72b) formed in a recessed shape at the peripheral edge thereof. The first engaging portion 71a and the second engaging portion 72a are provided on the engaging member 69a, and the first engaging portion 71b and the second engaging portion 72b are provided on the engaging member 69b.

  The first engaging portion 71a is provided as a recessed portion that can be engaged with the lock pin 63a, and the first engaging portion 71b is provided as a recessed portion that can be engaged with the lock pin 63b. The second engaging portion 72a is provided as a recessed portion that can be engaged with the pin 67d, and the second engaging portion 72b is provided as a recessed portion that can be engaged with the pin 67e. In the pin 67d, a portion that can be engaged with the second engaging portion 72a is provided as a portion that is stepwise expanded on the same axis with respect to a portion that can be in contact with the guide groove 43b. In the pin 67e, a portion that can be engaged with the second engaging portion 72b is provided as a portion having a stepped diameter on the same axis with respect to a portion that can contact the guide groove 43c.

  The pair of urging springs (70a, 70b) are provided as coiled spring members that urge the pair of engaging members (69a, 69b) to rotate in a predetermined direction. The biasing spring 70a is wound in a coil shape after one end of the spring member wound in a coil shape is locked to a protrusion provided on the guide plate 43 and wound around the rotation shaft 73a. The other end of the spring member is locked to a protrusion provided on the engaging member 69a. Accordingly, the biasing spring 70a is configured to bias the engaging member 69a so as to rotate in the counterclockwise direction when viewed from the inside in the vehicle width direction around the rotation shaft 73a.

Further, the biasing spring 70b is coiled after one end of the coiled spring member is locked to the protrusion provided on the guide plate 43 and wound around the rotation shaft 73b. The other end of the wound spring member is locked to a protrusion provided on the engagement member 69b. Thus, the biasing spring 70b is about the rotation shaft 73b, and is configured to bias so as to rotate the engagement member 69 b in the clockwise direction as viewed from the vehicle width direction inside.

  FIG. 23 schematically shows a state in which the link mechanism 64 is engaged with the second engaging portions (72a, 72b) of the engaging members (69a, 69b) in a linear state in a state where the doors (108, 109) are in the closed position. FIG. In FIG. 23, the link mechanism 64, the engagement members (69a, 69b), the long holes 43a, the guide grooves (43b, 43c), the output roller 22a, and the like viewed from the front side (from the vehicle width direction inside). The relationship is schematically shown.

  In the state shown in FIGS. 22 and 23, the link mechanism 64 is engaged with the engaging members (69a, 69b) in a linear state, and the engaging members (69a, 69b) are connected to the first engaging portions (71a, 69b). 71b) is engaged with the lock pins (63a, 63b). In this state, when the driving force output by swinging the carrier 20c of the planetary gear mechanism 20 is output to the output roller 22a of the lock output unit 22, the output roller 22a passes the elongated hole 43a in the direction of arrow K in the figure. Moving.

  As described above, the output roller 22a abuts on the recess 68 of the link 64a, and the link 64a rotates around the connecting pin 67a. And a link (64b, 64c) rotates relatively with respect to the link 64a, and the link mechanism 64 will be in a bending state. Thereby, it will be in the state from which engagement of the both ends of the link mechanism 64 with respect to the 2nd engaging part (72a, 72b) of an engaging member (69a, 69b) was released. The rack and pinion mechanism 53b is operated by the driving force output from the ring gear 20d of the planetary gear mechanism 20, and the arm members (66a, 66b) together with the driving racks (60a, 60b) or the connecting portions (59a, 59b). As a result, the lock pins (63a, 63b) also move away from each other in the opening direction of the doors (108, 109).

  When the lock pins (63a, 63b) are moved as described above, the engagement between the link mechanism 64 and the engagement members (69a, 69b) is released, so that the engagement members (69a, 69b) are biased springs. (70a, 70b) is rotated in the direction urged, and the engagement between the lock pins (63a, 63b) and the first engaging portions (71a, 71b) of the engaging members (69a, 69b) is released. It will be. Then, the state of the link mechanism 64 and the engaging members (69a, 69b) shifts to the state shown in FIG.

  In the state shown in FIG. 24, the link holding mechanism 65 is in a state in which no force is applied from the outside, and the engaging members (69a, 69b) are driven by the spring force of the urging springs (70a, 70b). The state shown in FIG. In this state, the engaging members (69a, 69b) restrain the movement of the link mechanism 64 extending in a linear state by the outer edge portions (74a, 74b). That is, the outer edge portion 74a of the engaging member 69a restrains the movement of the end portion of the link mechanism 64 on the pin 67d side, and the outer edge portion 74b of the engaging member 69b restrains the movement of the link mechanism 64 on the pin 67e side. . Thus, when the link mechanism 64 is held in the bent state by the link holding mechanism 65, the output roller 22a is held in the recess 68 of the link 64a, and the output to the carrier 20c in the planetary gear mechanism 20 is fixed. Maintained.

  On the other hand, when the rack and pinion mechanism 53b operates in the reverse direction, the arm members (66a, 66b) and the lock pins (63a, 63b) move toward each other toward the closing direction of the door (108, 109). Will do. When the lock pins (63a, 63b) move in this way, the lock pins (63a, 63b) engage with the first engagement portions (71a, 71b) of the engagement members (69a, 69b), and the engagement members ( 69a, 69b) rotate in the direction opposite to the direction biased by the biasing springs (70a, 70b). Then, the state of the link mechanism 64 and the engaging members (69a, 69b) shifts to the state shown in FIG.

  In the state shown in FIG. 25, the second engaging portions (72a, 72b) of the engaging members (69a, 69b) are opposed to both ends of the link mechanism 64, and the link mechanism 64 is engaged with the engaging members (69a, 69b). ) Can be engaged. In this state, the carrier 20c of the planetary gear mechanism 20 is swung, and the output roller 22a of the lock output unit 22 moves in the direction of the arrow L in the drawing so that the link 64a is output in the vicinity of the connecting pin 67c. The roller 22a is energized. As a result, the link 64a rotates about the connecting pin 67a, and the link mechanism 64 is deformed from the bent state to the linear state. As shown in FIGS. 22 and 23, both end portions of the link mechanism 64 are engaged with the second engaging portions (72a, 72b) of the engaging members (69a, 69b).

FIG. 26 is a plan view showing the lock fixing portion 62 and the lock moving portion 37 in the lock mechanism 57. The lock fixing portion 62 is configured as a block-like member provided to be fixed to the fixing base 51. The locking the fixing unit 62, the first surface 36a and the inclined surface 36 c configured similarly to the locking portion 36 of the first embodiment are provided. However, the lock fixing portion 62 is different from the lock fixing portion 36 of the first embodiment in that the second surface 36b is not provided.

  In the second embodiment, the engaging members (69a, 69b) of the link holding mechanism 65 are provided with outer edge portions (74a, 74b) that hold the link mechanism 64 in a bent state. Therefore, the outer edge portions (74a, 74b) of the planetary gear mechanism 20 are rotated so that the drive pinion 61 is rotationally driven by the driving force input from the ring gear 20d of the planetary gear mechanism 20 to the rack and pinion mechanism 53b. The function of generating a reaction force that balances the driving force input from the carrier 20c to the lock mechanism 57 is performed. Accordingly, it is not necessary to provide the lock fixing portion 62 with the second surface 36b similar to that of the first embodiment.

The lock moving unit 37 is provided so as to be movable by a driving force output from the carrier 20 c of the planetary gear mechanism 20 to the lock mechanism 57. The lock moving portion 37 is configured to abut against the lock fixing portion 62 on the inner side in the vehicle width direction at the closed position of the door (108, 109) . Thus, the lock mechanism 57 moves the door (108, 109) outward in the vehicle width direction when the door (108, 109) is closed by the lock moving part 37 coming into contact with the lock fixing part 62. It is provided to regulate.

  The lock moving unit 37 is configured in the same manner as the lock moving unit 37 of the first embodiment, and includes a slide contact unit 38 that can contact the lock fixing unit 62, a slide rail 39, and a transmission member 40. Has been. The slide contact portion 38 includes a slide block 41 and a roller 42 as in the first embodiment. The slide rail 39 and the transmission member 40 are also configured in the same manner as in the first embodiment.

  In the second embodiment, the transmission member 40 is fixed to the output roller shaft 22b in the lock output unit 22 (see FIG. 21). Although illustration of the guide plate 43 is omitted in FIG. 21, the output roller shaft 22 b passes through the long hole 43 a of the guide plate 43 and is fixed to the lower end side of the transmission member 40. The output roller 22a is rotatably supported at a position corresponding to the long hole 43a with respect to the output roller shaft 22b penetrating the long hole 43a.

[Operation of plug door device]
Next, the operation of the plug door device 1 will be described. As shown in FIGS. 16 to 21, when the doors (108, 109) are in the closed position, the shaft portions 54 (54a, 54b) are connected to the first links 24 and the second links in the guide portions 55 (55a, 55b), respectively. The link 25 is engaged.

  When the doors (108, 109) are in the closed position, as shown in FIGS. 20, 21, and 26, the lock mechanism 57 has the roller 42 in contact with the first surface 36a of the lock fixing portion 62. . For this reason, the movement of the slide base 52 to the outside in the vehicle width direction is restricted via the lock mechanism 57 and the carrier 20c of the planetary gear mechanism 20. As a result, the plug operation to the outside in the vehicle width direction by the plug mechanism is restricted and locked so that the movement of the doors (108, 109) is restricted.

  When the direct drive brushless electric motor 21 of the door drive mechanism 53 is driven from the above-mentioned closed position, the sun gear 20a of the planetary gear mechanism 20 starts rotating, and the planetary gear 20b around the sun gear 20a is rotated. Revolving around the sun gear 20a is started while meshing with the ring gear 20d. Then, the output roller 22a and the output roller shaft 22b move in the long hole 43a in the direction indicated by the arrow K in FIG. 23 due to the swing of the carrier 20c accompanying the revolution of the planetary gear 20b.

As a result, the transmission member 40 moves together with the output roller shaft 22b in parallel with the opening direction of the door 108 in the longitudinal direction of the vehicle, and the slide block 41 also moves on the slide rail 39 in parallel with the opening direction of the door 108. Then, the link mechanism 64 is engaged with the second engaging portions (72a, 72b) of the engaging members (69a, 69b) at both end portions, and the first end of the both end portions is changed. It will shift to the bending state from which the engagement to 2 engaging part (72a, 72b) was disengaged.

  As a result, the roller 42 that has been in contact with the first surface 36a moves to a position that is out of the first surface 36a. And until the lock pin (63a, 63) engaged with the first engaging portion (71a, 71b) of the engaging member (69a, 69b) is disengaged from the first engaging portion (71a, 71b). Will move. In FIG. 26, the position of the roller 42 that has moved to a position off the first surface 36a is shown as a two-dot chain line roller 42a. As a result, the locked state of the doors (108, 109) by the lock mechanism 57 is released, and the plug mechanism can be plugged outward in the vehicle width direction.

  As described above, when the transition to the state in which the plug operation to the outside in the vehicle width direction is possible, the drive of the brushless electric motor 21 of the door drive mechanism 53 is continued further. As a result, the driving force output to the drive pinion 61 of the rack and pinion mechanism 53b via the ring gear 20d is further transferred to the shaft portion (54a) via the drive rack (60a, 60b) and the connecting portion (59a, 59b). , 54b). Therefore, each of the shaft portions (54a, 54b) biases the second links 25 of the respective guide portions (55a, 55b) in the same direction so as to move the doors (108, 109) in the opening direction. And each guide part (55a, 55b) operate | moves similarly to the guide part 15 of 1st Embodiment. That is, when the doors (108, 109) are opened, the guide portions (55a, 55b) rotate while abutting on the shaft portions (54a, 54b) so that the shaft portions (54a, 54b) are in the vehicle width direction. The shaft portions (54a, 54b) are guided so as to move in the (opening direction of the door 108 and opening direction of the door 109).

  Further, when the guide portions (55a, 55b) are operated as described above, a force directed outward in the vehicle width direction acts on the shaft portions (54a, 54b). Therefore, a force directed outward in the vehicle width direction also acts on the door drive mechanism 53 connected to the shaft portions (54a, 54b) via the connection portions (59a, 59b), and the door drive mechanism 53 is installed. A force directed outward in the vehicle width direction also acts on the slide base 52.

  As described above, the door drive mechanism 53 and the slide base 52 are guided by the slide support portion 51b in the fixed base 51 and moved outward in the vehicle width direction. As a result, a plug operation in which the doors (108, 109) move outward in the vehicle width direction is performed. Then, by performing the plug operation, the doors (108, 109) can be moved in the opening direction.

  Further, when the plug operation to the outside in the vehicle width direction by the plug mechanism is completed, the slide contact portion 38 installed on the slide rail 39 fixed to the slide base 52 also moves to the outside in the vehicle width direction together with the slide base 52. It will be. Accordingly, the roller 42 located at the position shown as the two-dot chain line roller 42a in FIG. 26 moves to the position shown as the one-dot chain line roller 42b. At this time, unlike the first embodiment, the roller 42 is not in contact with the lock fixing portion 62. However, as shown in FIG. 24, the movement of both ends of the link mechanism 64 in the bent state is restrained by the outer edges (74a, 74b) of the engaging members (69a, 69b).

  The lock output unit 22 connected to the carrier 20c of the planetary gear mechanism 20 has an urging means (not shown) such as a spring for urging the output roller 22a in the direction opposite to the direction indicated by the arrow K in FIG. Is provided. In a state where both ends of the link mechanism 64 are in contact with and restrained by the outer edges (74a, 74b) of the engaging members (69a, 69b), the urging force of the urging means is applied to the output roller 22a and the link mechanism 64. By acting, the state where the link mechanism 64 is pressed against the outer edge portions (74a, 74b) of the engaging members (69a, 69b) is maintained.

  Further, in a state where both end portions of the link mechanism 64 are pressed against and contacted with the outer edge portions (74a, 74b) of the engagement members (69a, 69b), the link mechanism 64 is input from the carrier 20c of the planetary gear mechanism 20 to the lock mechanism 57. A reaction force that balances the driving force is generated at the outer edge portions (74a, 74b). Accordingly, the drive pinion 61 is rotationally driven by the driving force input to the drive pinion 61 from the ring gear 20d of the planetary gear mechanism 20.

As the drive pinion 61 rotates, the drive racks (60a, 60b) are driven in opposite directions, and the support rails 16d and the pinions 16c in the double speed rails (56a, 56b) move together with the connecting portions (59a, 59b). . Therefore, in each double-speed rail (56a, 56b), the upper rack 16a connected to the door (108, 109) is double-speed with respect to the pinion 16c with respect to the lower rack 16b fixed to the slide base 52. Will move. As a result, the doors (108, 109) move in the opening direction, and the doors (108, 109) are opened. Note that during the movement in the opening direction of the door (108, 109), the shaft portion (54a, 54b), the guide portions (55 a, 55b) receives no force in the vehicle width direction from the connecting portion (59a 59b) moves linearly in the opening direction of the door (108, 109).

On the other hand, when the doors (108, 109) are closed, an operation opposite to the opening operation of the doors (108, 109) described above is performed. That is, the direct drive type brushless electric motor 21 in the door drive mechanism 53 is driven, and the drive pinion 61 driven via the planetary gear mechanism 20 rotates in the opposite direction to that in the above-described opening operation. Thereby, the support rail 16d and the pinion 16c in each double speed rail (56a, 56b) connected to the connecting portion (59a, 59b) move in the opposite direction to the case of the opening operation described above. In each double speed rail (56a, 56b), the upper rack 16a connected to the door (108, 109) moves at a double speed relative to the pinion 16c with respect to the lower rack 16b fixed to the slide base 52. To do. As a result, the doors (108, 109) move in the closing direction, and the doors (108, 109) are closed. Further, the shaft portions (54a, 54b) move linearly in the closing direction toward the guide portions (55a, 55b), respectively.

Therefore, the shaft portions (54a, 54b) abut against the second links 25 in the respective guide portions (55a, 55b) when the doors (108, 109) move a predetermined amount in the closing direction from the fully open position. The second link 25 is energized. And each guide part (55a, 55b) operate | moves similarly to the guide part 15 of 1st Embodiment. That is, when the doors (108, 109) are closed, the guide portions (55a, 55b) rotate while contacting the shaft portions (54a, 54b) so that the shaft portions (54a, 54b) are in the other direction in the vehicle width direction. The shaft portions (54a, 54b) are guided so as to move in the (closing direction of the door 108 and closing direction of the door 109). At this time, the doors (108, 109) move in the same manner as the shafts (54a, 54b). That is, the door (108, 109) is configured to move linearly in a position either et closing direction fully open, in the closed position near the unit, the process proceeds to the closed position is drawn in the vehicle width direction inside. Thereby, the plug operation to the inside in the vehicle width direction by the plug mechanism is completed.

  Further, when the plug operation to the inside in the vehicle width direction by the plug mechanism is completed, the slide contact portion 38 installed on the slide rail 39 fixed to the slide base 52 also moves in the vehicle width direction along with the slide base 52. It will be. As a result, the roller 42 located at the position shown as the one-dot chain line roller 42b in FIG. 26 moves to the position shown as the two-dot chain line roller 42a. At this time, the lock pins (63a, 63b) engage with the first engaging portions (71a, 71b) of the engaging members (69a, 69b), respectively, and rotate the engaging members (69a, 69b). I am letting. Thereby, the 2nd engaging part (72a, 72b) of an engaging member (69a, 69b) is in the state which opposed the both ends of the link mechanism 64 of a bending state.

  Then, when the engaging members (69a, 69b) are rotated as described above, the link mechanism 64 is released from being restrained by the outer edges (74a, 74b) of the engaging members (69a, 69b). For this reason, the link 64a rotates by the driving force input from the carrier 20c of the planetary gear mechanism 20 via the output roller 22a, and the link mechanism 64 is deformed from the bent state to the linear state. Then, both end portions of the link mechanism 64 are engaged with the second engaging portions (72a, 72b) of the engaging members (69a, 69b).

  At this time, due to the driving force input from the carrier 20c via the output roller shaft 22b, the transmission member 40 moves in parallel with the closing direction of the door 108 in the front-rear direction of the vehicle, and the slide block 41 also moves on the slide rail 39. Is moved in parallel with the closing direction of the door 108. Then, the roller 42 moves from the position shown as the two-dot chain line roller 42 a in FIG. 26 to the position where it abuts on the first surface 36 a of the lock fixing portion 62. Thereby, the locked state of the doors (108, 109) by the lock mechanism 57 is ensured, and the plug mechanism cannot be plugged outward in the vehicle width direction.

Movement outward in the direction is restricted. For this reason, when the doors (108, 109) are closed, the doors (108, 109) are restrained so that they do not move more reliably and do not move outward in the vehicle width direction. Therefore, the doors (108, 109) can be locked without rattling when closed.

  Therefore, according to the present embodiment, a small plug door device 2 that can perform an opening / closing operation and a plug operation by the door drive mechanism 53 that applies a force in the vehicle front-rear direction to the door (108, 109) is realized. Further, it is possible to provide a plug door device 2 that can lock the doors (108, 109) without looseness when closed.

  Further, according to the plug door device 2, the door driving mechanism is actuated by the driving portion 53a having the direct drive type brushless electric motor 21 and the driving force from the driving portion 53a, thereby connecting the connecting portions (59a, 59b). And a rack and pinion mechanism 53b for moving the doors (108, 109). Therefore, a double-drawing draw door provided as a pair of doors (108, 109) installed at the entrance / exit 106 by a pair of drive racks (60a, 60b) that move in opposite directions in the rack and pinion mechanism 53b. Can be opened and closed simultaneously. Accordingly, the drawing doors (108, 109) can be opened and closed by one brushless electric motor 21. Further, according to the plug door device 2, the drive unit 53 a includes the direct drive type brushless electric motor 21 and the planetary gear mechanism 20. In the sun gear 20a, the carrier 20c, and the ring gear 20d of the planetary gear mechanism 20, the driving force of the brushless electric motor 21 is input to one of them, and the driving force from the other one is output to the rack and pinion mechanism 53b. The driving force from the remaining one is output to the lock mechanism 57. Therefore, the single brushless electric motor 21 can perform the opening / closing operation of the double-drawing draw doors (108, 109), the plug operation, and the locking operation of the door (108, 109) by the lock mechanism 57. An efficient drive unit 53a can be realized.
