[Operation of plug door device]
Operation | movement of the plug door apparatus 1 is demonstrated with reference to FIGS.

<Operation when opening the door>
As shown in FIGS. 5 and 8 (a), when the door is fully closed, the shaft portion 5a (shown schematically with a hatched pattern in FIGS. 5 to 8) is fixed base in plan view. 2 in the recess 2a. The shaft portion 5a is engaged with both the first notch portion 61a of the first link 61 and the second notch portion 62a of the second link 62 (that is, the shaft portion is located in the notch portion). is doing).

  By driving a motor (not shown) of the door drive device 4 and rotating the pinion 42c in the forward direction, a driving force in the opening direction acts on the pair of racks 42a and 42b. The driving force in the opening direction is transmitted to the shaft portion 5a via the first bracket 43a, the support rail 49, and the second bracket 44a. That is, the shaft portion 5a urges the second link 62 in the same direction so as to move in the opening direction (the direction of the arrow A1 in FIG. 8).

  Here, as shown in FIG. 8A, the rotation of the second link 62 relative to the first link 61 (rotation in the direction of the arrow Rb1) is a position where the roller 65 abuts on the inclined surface 71 of the roller guide 7. It is regulated. Therefore, the second link 62 hardly rotates with respect to the first link 61, and turns to the first link 61 via the second rotation shaft 64 (in the direction of the arrow Ra <b> 1). Power). As a result, as shown in FIG. 8B, the roller 65 moves along the inclined surface 71 and the first link 61 rotates around the first rotation shaft 63.

Further, in a plan view, the first notch portion 61a of the first link 61 and the second notch portion 62a of the second link 62 maintain a state surrounding the shaft portion 5a.

  When the shaft portion 5 a further moves in the opening direction from the state shown in FIG. 8B, the contact position between the roller 65 and the roller guide 7 shifts from the inclined surface 71 to the curved surface 72. Accordingly, the roller 65 is drawn inward in the vehicle width direction along the curved surface 72, and the second link 62 rotates relative to the first link 61 in the direction of the arrow Rb1. That is, as shown in FIG. 8C, the restraint of the shaft portion 5a by the second link 62 is released.

Here, in the fully closed state, the first link 61 is disposed such that the first cutout portion 61 a is positioned on the outer side in the vehicle width direction than the position of the first rotation shaft 63. In the present embodiment, the vehicle passes through a straight line connecting the center of the shaft portion 5a accommodated in the first cutout portion 61a and the center of the first rotation shaft 63 and the first rotation shaft 63 in plan view. An angle formed by a straight line extending in parallel with the front-rear direction (an angle indicated by θ in FIG. 8A) is configured to be within a range of 5 to 10 °.
Further, in the fully closed state, the roller 65 is positioned on the outer side in the vehicle width direction from the center of the shaft portion 5a, and the second rotating shaft 64 is positioned on the inner side in the vehicle width direction from the center of the shaft portion 5a. The second link 62 is arranged.
With such a configuration, the urging force from the shaft portion 5a can be used for the rotation of the first link 61 efficiently.

  When the 1st link 61 rotates as mentioned above, the force which faces the vehicle width direction outer side acts with respect to the axial part 5a. Similarly, a force that faces the outside in the vehicle width direction also acts on the other shaft portion 5b. Therefore, a force directed outward in the vehicle width direction also acts on the door drive device 4 connected to the shaft portion 5a and the shaft portion 5b, and the vehicle width also affects the slide base 3 to which the door drive device 4 is fixed. A force directed outward in the direction acts.

  Thereby, the door drive device 4 and the slide base 3 are guided to the linear guide 31 and moved outward in the vehicle width direction. As a result, as shown in FIG. 6, the doors 104a and 104b can be moved in the opening direction while being moved outward in the vehicle width direction.

Thereafter, as shown in FIG. 7, the shaft portion 5 a does not receive a force in the vehicle width direction from the guide portion 6 a, and moves linearly in the opening direction by driving the door driving device 4. That is, the door 104a moves linearly to the fully open position in the opening direction.
At this time, the shaft portion 5a moves along the peripheral edge portion of the fixed base 2 extending in the vehicle front-rear direction. Therefore, even if an external force inward in the vehicle width direction is applied to the door 104a, the shaft portion 5a comes into contact with the peripheral edge of the fixed base 2, so that the slide base 3 is not pushed inward in the vehicle width direction.
Further, the shaft portion 5 a moves along the groove 32 a of the slide base 3. For this reason, even if an external force is applied to the door 104a in the vehicle width direction outside, the movement of the shaft portion 5a in the vehicle width direction outside is restricted by the edge of the groove 32a. This can be suppressed. Since the movement of the slide base 3 to the outside in the vehicle width direction is regulated by the stopper 22, the slide base 3 is not moved by the external force to the outside in the vehicle width direction. Similarly, the movement of the shaft portion 5b in the vehicle width direction is restricted by the groove 32b.

<Operation when closing the door>
When the door is closed, an operation opposite to the door opening operation described above is performed.

  That is, by driving a motor (not shown) of the door drive device 4 and rotating the pinion 42c in the reverse direction, a driving force in the closing direction acts on the pair of racks 42a and 42b. The driving force in the closing direction is transmitted to the shaft portion 5a, and the shaft portion 5a linearly moves in the closing direction (the direction of arrow A2 in FIG. 8) toward the guide portion 6a.

  Here, in the state where the door is opened, as shown in FIG. 8C, the turning force in the Rb1 direction acts on the second link 62 by the helical spring 67. That is, a pulling force is applied to the second link 62 from the helical spring 67 so that the roller 65 is positioned on the curved surface 72 of the roller guide 7. In the present embodiment, the roller 65 enters the concave portion 72 a having an arc shape substantially the same as the outer peripheral shape of the roller 65 on the curved surface 72. Accordingly, the first link 61 and the second link 62 are stably held at predetermined positions. Specifically, the second link 62 is held at a position where the shaft portion 5a that has linearly moved in the closing direction can abut on the inner edge of the second notch portion 62a. Moreover, the 1st link 61 is also hold | maintained in the position which can accommodate the axial part 5a which has moved linearly in the closing direction in the 1st notch part 61a.

  Therefore, the shaft portion 5a abuts against the inner edge of the second cutout portion 62a of the second link 62 when the shaft portion 5a moves a predetermined amount in the closing direction from the fully opened position (see FIG. 8C), and the second link 62 is Energize. At this time, the second link 62 rotates in the direction of the arrow Rb2 against the force of the helical spring 67, so that the linear movement in the closing direction of the shaft portion 5a is not hindered. When the second link 62 rotates, the roller 65 moves along the curved surface 72 of the roller guide 7. When the second link 62 is rotated, the first link 61 is held at a predetermined position or in the vicinity thereof with little rotation.

  Then, the shaft portion 5a moves in the closing direction to a position where it comes into contact with the inner edge of the first cutout portion 61a of the first link 61, and biases the first link 61 in the closing direction. Thereby, the first link 61 rotates in the direction of the arrow Ra2, and the shaft portion 5a is guided inward in the vehicle width direction. That is, the shaft portion 5 a is guided into the recessed portion 2 a of the fixed base 2.

  The door 104a moves similarly to the shaft portion 5a. That is, the door 104a moves linearly in the closing direction from the fully open position, and is drawn inward in the vehicle width direction in the vicinity of the fully closed position to move to the fully closed position. The door 104b is closed similarly to the door 104a.

[Operation of the pivot arm when the door is opened and closed]
Hereinafter, the operation of the rotating arm when the door is opened and closed will be described.

  As described above, when the door starts to move in the opening direction from the fully closed position, the slide base 3 moves outward in the vehicle width direction. As a result, as shown in FIGS. 5 and 6, the connecting rod 86 having one end connected to the slide base 3 is also moved outward in the vehicle width direction so as to push the upper turning arm 81 outward in the vehicle width direction. Rush. The upper turning arm 81 is urged by the connecting rod 86 to apply an urging force to the outside in the vehicle width direction in the vicinity of the end of the door bottom of the door 104a via the upper rail 85 (see FIG. 4). Rotate while letting

  Further, as the upper rotation arm 81 rotates, the lower rotation arm 82 also rotates in the same direction via the connecting shaft 83. That is, the lower rotation arm 82 rotates while exerting an urging force to the outside in the vehicle width direction in the vicinity of the door bottom side end portion of the door 104a via the lower rail 88.

  Thereby, the door 104a is urged | biased by the vehicle width direction outer side in the vicinity of a door butt side edge part vicinity of an upper end part and a lower end part, and is moved to the vehicle width direction outer side.

  When closing the door, as described above, the slide base 3 moves inward in the vehicle width direction in the vicinity of the fully closed position. Accordingly, the connecting rod 86 having one end connected to the slide base 3 also moves inward in the vehicle width direction and urges the upper turning arm 81 to be pulled inward in the vehicle width direction. The upper rotating arm 81 is rotated by being biased by the connecting rod 86 and exerting a pulling force inward in the vehicle width direction in the vicinity of the door bottom side end portion of the door 104a via the upper rail 85. .

  Further, as the upper rotation arm 81 rotates, the lower rotation arm 82 also rotates in the same direction via the connecting shaft 83, and the door bottom side in the vicinity of the lower end of the door 104 a via the lower rail 88. An urging force inward in the vehicle width direction is applied to the vicinity of the end.

  As a result, the door 104a is urged inward in the vehicle width direction in the vicinity of the upper end portion and in the vicinity of the lower end portion in the vicinity of the door bottom side end portion, and is moved inward in the vehicle width direction.

  During the opening operation and the closing operation, the roller 84 provided at the distal end of the upper rotational arm 81 and the roller provided at the distal end of the lower rotational arm 82 respectively move the door 104a in the opening / closing direction. Along with this, while rolling along the upper rail 85 and the lower rail, it moves relative to the door 104a.

[Lock operation]
As shown in FIG. 2, in the present embodiment, when the door is in a fully closed state, the locking brackets 91a and 91b are engaged to move the first brackets 43a and 43b in the opening direction (that is, A lock mechanism 90 that can lock the movement of the doors 104a and 104b in the opening direction) is provided. The lock mechanism 90 is provided in the main body 41 of the door drive device 4 and is switched between a locked state and an unlocked state as follows.

An output shaft of a motor (not shown) provided in the door driving device 4 can transmit a driving force to the pinion 42c and the lock mechanism 90 via the planetary gear mechanism G.
The planetary gear mechanism G includes a sun gear G1 rotatably supported, a planetary gear G2 arranged on the outer periphery of the sun gear G1 and capable of rotating and revolving while meshing with the sun gear G1, and the planetary gear G2 on the outside. It has an internal gear G3 having internal teeth that mesh with each other, and a carrier C that rotatably supports the planetary gear G2. The sun gear G1, the internal gear G3, and the carrier C are arranged so that their rotational axes coincide with each other, and are arranged so as to be rotatable relative to each other. Further, the three rotation axes coincide with the rotation axis of the pinion 42c of the rack and pinion mechanism.

The sun gear G1 is connected to the output shaft of the motor. In addition, you may connect suitably via a deceleration mechanism.
The internal gear G3 is connected to the pinion 42c via a bolt or the like (not shown).
The carrier C is connected to the lock mechanism 90. Further, the carrier C is applied with a predetermined urging force that suppresses the rotation of the carrier C accompanying the revolution of the planetary gear G2 during the door closing operation.

  With such a configuration, the carrier C does not normally rotate until the door reaches the fully closed position during the closing operation. When the door reaches the fully closed position, the door cannot move in the closing direction, so that the rotation of the internal gear G3 is also prevented. Therefore, the driving force of the motor is transmitted to the carrier C. Thereby, the carrier C rotates against the predetermined urging force, and the lock mechanism 90 shifts to the locked state.

  On the other hand, when the door is moved from the fully closed position in the opening direction, the locking shaft portions 91a and 91b are prevented from moving by the lock mechanism 90 in the locked state at the start of movement in the opening direction. This prevents the internal gear G3 from rotating. Therefore, the carrier C rotates in the direction opposite to the direction rotated during the closing operation. Thereby, the lock mechanism 90 shifts to the unlocked state. Here, the carrier C is configured to be restricted in rotation at a position rotated by a predetermined angle. Therefore, after the rotation of the carrier C is restricted, the driving force of the motor is transmitted to the internal gear G3, and the door moves in the opening direction.

  The lock mechanism 90 can regulate the movement of the locking shaft portions 91a and 91b in the opening direction in conjunction with the rotation of the carrier C when the door is in the fully closed position. What is necessary is just to be comprised so that the said regulation can be cancelled | released. For example, a known lock mechanism described in Patent Documents 2 and 3 can be used.

  As described above, the plug door device 1 according to the present embodiment includes the fixed base 2 fixed to the frame 103, the slide base 3 provided on the fixed base 2 so as to be movable in the vehicle width direction, and the slide base 3. A door driving device 4 that is provided and moves the doors 104a, 104b in the longitudinal direction of the vehicle via the first brackets 43a, 43b, and shafts 5a, 5b fixed to the first brackets 43a, 43b, When the doors 104a and 104b are opened, the shafts 5a and 5b are pivotably mounted on the base 2 so that the shafts 5a and 5b move outward in the vehicle width direction by rotating while contacting the shafts 5a and 5b. 5b is guided, and when the doors 104a and 104b are closed, the shafts 5a and 5b are guided so that the shafts 5a and 5b move inward in the vehicle width direction by rotating while contacting the shafts 5a and 5b. Guide part 6 , Comprising a 6b, the.

  According to this configuration, the guide portions 6a and 6b abut on the shaft portions 5a and 5b and rotate to guide the shaft portions 5a and 5b in the vehicle width direction. Therefore, the guide parts 6a and 6b operate so as to follow the movement of the doors 104a and 104b in the vehicle width direction. Thereby, in the state in which the doors 104a and 104b were pulled in the vehicle width direction inside, it can suppress that the guide parts 6a and 6b protrude too much to the vehicle width direction outer side. Therefore, the space occupied by the guide portions 6a and 6b can be further reduced. As a result, the door driving device 4 that applies a force in the front-rear direction of the vehicle to the doors 104a and 104b can perform an opening / closing operation and a plug operation, and the plug door device 1 can be formed in a small size.

  It should be noted that the door is not limited to a configuration in which the door is pulled inward in the vehicle width direction during close operation and is brought into close contact with the peripheral portion of the entrance / exit. It may be a configuration.

  Further, the slide base 3 is disposed below the fixed base 2, and the guide portions 6a and 6b are disposed above.

According to this configuration, the slide base 3 and the guide portions 6 a and 6 b provided to be movable relative to the fixed base 2 can be provided closer to the fixed base 2. Thereby, the whole apparatus can be reduced in size.
That is, if both the slide base 3 and the guide portions 6a and 6b are provided on one side of the fixed base 2, they are arranged at appropriate positions so that the slide base 3 and the guide portions 6a and 6b do not interfere with each other during movement. There is a need. In this case, useless space is likely to occur. In this respect, by arranging the slide base 3 and the guide portions 6a and 6b separately on the upper and lower sides of the fixed base, mutual interference does not have to be taken into consideration, so that the space required for the arrangement does not become excessively large.

  Further, since the slide base 3 and the guide portions 6a and 6b can be provided closer to the fixed base 2, the connection of the slide base 3 and the guide portions 6a and 6b to the fixed base 2 is stabilized. Therefore, the operations of the slide base 3 and the guide portions 6a and 6b can be stabilized.

  In addition, the structure which arrange | positions a guide part on the upper side of the fixed base 2, and arrange | positions a slide base on the lower side may be sufficient.

Further, the guide portion 6a (the same applies to the guide portion 6b) is provided with a first link 61 that is rotatably provided on the fixed base 2, a roller 65 that is provided rotatably on the first link 61. The roller guide 7 further includes a second link 62, is fixed to the fixed base 2, and guides the roller 65.
When the door is opened, the first link 61 receives a force from the shaft portion 5a via the second link 62, and rotates by a predetermined angle so as to move the shaft portion 5a outward in the vehicle width direction. The roller guide 7 guides the roller 65 so that the second link 62 is in contact with the shaft portion 5a until the first link 61 rotates by a predetermined angle, and the first link 61 is predetermined. After the angular rotation, the roller 65 is guided so that the second link 62 does not hinder the movement of the shaft portion 5a.
Further, when closing the door, the first link 61 receives a force from the shaft portion 5a and rotates so as to move the shaft portion 5a inward in the vehicle width direction.

  According to this configuration, the guide portion 6a that guides the shaft portion 5a outward in the vehicle width direction when opening the door and guides the shaft portion 5a inward in the vehicle width direction when closing the door is realized with a simple configuration. Can do.

  Further, a helical spring 67 is provided between the first link 61 and the second link 62 and biases the second link 62 so that the roller 65 approaches the roller guide 7.

  According to this configuration, since the roller 65 is urged toward the roller guide 7, the roller 65 can be prevented from being separated from the roller guide 7. This makes it possible to move the roller 65 along the roller guide 7 more reliably.

Further, the first link 61 and the second link 62 can be held at predetermined positions by the elastic force of the helical spring 67. That is, the opening sides of the notches 61a and 61b are extended outward in the width direction from the fixed base 2, and the opening sides of the notches 61a and 61b are directed in the opening direction (in FIG. 8C). It is possible to hold the first link 61 and the second link 62 in the state shown in FIG.
Thereby, the shaft part 5a can be reliably guided into the notches 61a and 61b of the first link 61 and the second link 62 during the closing operation.

  Note that the second link is not necessarily biased using the helical spring, but another elastic member may be used, or a configuration in which the second link is biased using a magnetic force or the like may be used.

  The slide base 3 has grooves 32a and 32b extending in the longitudinal direction of the vehicle. The shaft portions 5a and 5b are inserted into the grooves 32a and 32b, and the groove 32a is opened when the doors 104a and 104b are opened and closed. , 32b.

  According to this configuration, the movement of the shaft portions 5a and 5b in the vehicle width direction can be restricted by the edge portions of the grooves 32a and 32b. Thereby, even when a force in the vehicle width direction acts on the doors 104a and 104b, the doors 104a and 104b can be reliably held within a predetermined range in the vehicle width direction.

  The first brackets 43a and 43b for transmitting the driving force of the door driving device 4 to the door are connected to the doors 104a and 104b via the double speed rails 45a and 45b. Therefore, by moving the first brackets 43a and 43b by a predetermined distance by the door driving device 4, the doors 104a and 104b can be moved by a distance double the predetermined distance. Thereby, the space required for moving the first brackets 43a, 43b, the second brackets 44a, 44b, the shaft portions 5a, 5b, etc. linked thereto can be reduced.

  Further, since the slide base 3 is held by the three linear guides 31 provided on the fixed base 2 so as to be movable in the vehicle width direction, the connection between the slide base 3 and the fixed base 2 is stabilized. Thereby, deformation of the slide base 3 can be prevented. In addition, it becomes easy to move the slide base 3 straight in a stable manner in the vehicle width direction.

Further, the door drive device 4 uses the rack-and-pinion mechanism composed of the racks 42a and 42b and the pinion 42c for moving the first brackets 43a and 43b, and the rotational driving force from the motor as a drive source to the rack-and-pinion mechanism. And a planetary gear mechanism G that distributes to the pinion mechanism.
Moreover, it has the locking mechanism 90 for locking the movement of the doors 104a and 104b.
The planetary gear mechanism G is configured to distribute the rotational driving force from the motor to the rack and pinion mechanism and the lock mechanism 90.

  According to this configuration, the door driving device 4 using a motor as a driving source can perform an opening / closing operation, a plug operation, and a locking operation for locking the movement of the door.

In addition, the plug door device 1 according to the present embodiment is connected to both upper and lower sides of the entrance 102 so as to be rotatable about a vertically extending axis, and is connected to doors 104a and 104b that open and close. The upper rotating arm 81 and the lower rotating arm 82 are provided.
The upper turning arm 81 is connected to the slide base 3 via a connecting rod 86 so as to turn as the slide base 3 moves. Further, the lower rotating arm 82 is connected to the upper rotating arm 81 via a connecting shaft 83 and rotates as the slide base 3 moves.

According to this configuration, since the upper turning arm 81 is connected to the slide base 3 via the connecting rod 86, the driving force from the door driving device 4 is transmitted without passing through the doors 104a and 104b. That is, even if the doors 104a and 104b are not given excessively high rigidity, the upper turning arm 81 can be reliably turned.
The lower rotating arm 82 is connected to the slide base 3 via a connecting rod 86, an upper rotating arm 81, and a connecting shaft 83. Therefore, the lower rotation arm 82 can be reliably rotated by moving the slide base 3.

  The first brackets 43a and 43b of the door drive device 4 are directly fixed to the doors 104a and 104b, not only when the door drive device 4 and the doors 104a and 104b are connected using the double speed rails 45a and 45b. Is also possible. In this case, the amount of movement of the racks 42a and 42b of the door drive device 4 is doubled as compared with the case of using a double speed rail, but it can be realized with a simple configuration. In addition, even if the first brackets 43a, 43b and the like are fixed to the door ends of the doors 104a, 104b, the upper rotating arm 81 and the lower rotating arm 82 can be reliably rotated. Therefore, members such as the door drive device 4, the first brackets 43a and 43b, and the second brackets 44a and 44b can be arranged in a narrower range near the center of the entrance 102 in the front-rear direction of the vehicle. As a result, the plug door device can be formed in a small size.

  Further, since the upper turning arm 81 and the lower turning arm 82 are fixed to the same connecting shaft 83, the upper turning arm 81 is turned by the urging force from the slide base 3, thereby lowering the lower turning arm 81. The rotation arm 82 can be reliably rotated.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made as long as they are described in the claims.
