Definitions

  • the present invention relates to a plug door apparatus which is used for an entrance of a vehicle and allows a door to open or close and to conduct plugging (i.e. to move in a vehicle width direction).
  • Patent Document 1 recites a conventional plug door apparatus.
  • This plug door apparatus is arranged so that a guide groove which allows a door to move in the outward direction or inward direction and to slide in a front-back direction is formed in a fixed base which is fixed to a vehicle.
  • the guide groove includes a parallel groove portion in parallel to the side wall of the vehicle and a ramped groove portion which is continued from the parallel groove portion and is inclined with respect to the side wall.
  • the door is opened by using a door driver exerting a force to the door in a front-back direction of the vehicle, in such a way that the closed door is moved toward the outside of the side wall of the vehicle and then slid along the outer surface of the side wall.
  • the door is connected to a component transferring the driving force from the door driver at the anterior door end side.
  • the anterior door end side of the door is moved in the outward direction or inward direction so that an upper arm on the posterior door end side is swung in a vehicle width direction by the door.
  • the upper arm may not sufficiently rotate on account of reasons such as the warping of the door.
  • the posterior door end side of the door may contact the vehicle main body.
  • the lower part of the posterior door end side of the door which is far from the junction, is susceptible to contact the vehicle main body.
  • a conceivable solution to this problem of contact between the posterior door end side and the vehicle main body is to connect the door with the door driver at a part of the door which is close to the posterior door end side.
  • an object of the present invention is to provide a compact plug door apparatus.
  • the plug door apparatus of the present invention has the following features to achieve the object above.
  • the plug door apparatus of the present invention includes the following features singly or in combination.
  • the plug door apparatus of the present invention for achieving the object above includes: a fixed base fixed to a main body of a vehicle; a slide base provided on the fixed base to be movable in a width direction of the vehicle (hereinafter, vehicle width direction); a door driver which is provided in the slide base and moves a door in a front-back direction of the vehicle via a connecting member; an axis component connected to the connecting member; and a guide portion which is rotatably provided on the fixed base and, when the door is opened, rotates while contacting the axis component so as to guide the axis component so that the axis component moves in one width direction of the vehicle, whereas, when the door is closed, rotates while contacting the axis component so as to guide the axis component so that the axis component moves in the other width direction of the vehicle.
  • the guide portion rotates while contacting the axis component, so as to guide the axis component in a vehicle width direction.
  • the operation of the guide portion therefore follows the movement of the door in a vehicle width direction. This makes it possible to downsize the space occupied by the guide portion in the vehicle width direction, in accordance with the state of the movement of the door in the vehicle width direction.
  • the opening, closing, and plugging are carried out by the door driver which applies a force to the door in a front-back direction of the vehicle, and also the plug door apparatus is downsized.
  • the above-described plug door apparatus is preferably arranged so that the slide base is provided on one of an upper side or a lower side of the fixed base and the guide portion is provided on the other side of the fixed base.
  • the slide base and the guide portion arranged to be movable relative to the fixed base are provided to be closer to the fixed base. This facilitates the downsizing of the entirety of the apparatus.
  • the above-described plug door apparatus is preferably arranged so that the guide portion includes a first link rotatably provided on the fixed base and a second link rotatably provided on the first link and having a roller portion, a roller guide fixed to the fixed base to guide the roller portion is further provided, (a) when the door is opened, the first link receives a force from the axis component via the second link and rotates for a predetermined angle so as to move the axis component in one width direction of the vehicle, the roller guide guides the roller portion such that the second link is kept contacting the axis component while the first link is rotating for the predetermined angle, and then guides the roller portion so that the second link does not obstruct the movement of the axis component, after the first link rotates for the predetermined angle, (b)when the door is closed, the first link receives a force from the axis component and rotates so as to move the axis component in the other width direction of the vehicle.
  • the guide portion which guides the axis component toward one side in the vehicle width direction when closing the door, and guides the axis component toward the other side in the vehicle width direction when opening the door.
  • the above-described plug door apparatus is preferably arranged to include a biasing member which is provided between the first link and the second link and biases the second link to cause the roller portion to move close to the roller guide.
  • This structure prevents the roller portion from moving away from the roller guide because the roller portion is biased toward the roller guide. This makes it possible to certainly move the roller portion along the roller guide.
  • the above-described plug door apparatus is preferably arranged so that the slide base has a groove portion extending in the front-back direction of the vehicle, and the axis component is inserted into the groove portion and moves along the groove portion when the door is opened or closed.
  • the movement of the axis component in the vehicle width direction is stopped by the edge of the groove portion of the slide base. This makes it possible to keep the door within a predetermined range in the vehicle width direction, even if a force in the vehicle width direction is exerted to the door.
  • the above-described plug door apparatus is preferably arranged to include a double-speed rail in which a pinion is provided between two opposing racks, wherein, the two racks are disposed to extend in the front-back direction of the vehicle, one of the racks being connected to the slide base whereas the other one of the racks being connected to the door, and the pinion is connected to the connecting member.
  • the above-described plug door apparatus is preferably arranged so that the slide base is supported by a plurality of linear guides provided on the fixed base to be movable in the width directions of the vehicle.
  • the slide base is connected to the fixed base at plural positions in the vehicle front-back directions as a plurality of linear guides are provided, it is possible to prevent the deformation of the slide base. Furthermore, it becomes possible to cause the slide base to linearly and stably move in a vehicle width direction.
  • the above-described plug door apparatus is preferably arranged so that the door driver includes a rack-and-pinion mechanism for moving the connecting member and a planetary gear mechanism which transfers a rotational driving force from a drive source to the rack-and-pinion mechanism.
  • the planetary gear mechanism allows the rotational driving force from the drive source to be transferred to not only the rack-and-pinion mechanism for opening and closing the door but also another mechanism.
  • the driving force from the drive source can be used for driving a locking mechanism for preventing the movement of the door, via the planetary gear mechanism.
  • the above-described plug door apparatus is preferably arranged to include a rotation arm connected to the main body of the vehicle to be rotatable about a vertical axis and also connected to the door which is opened and closed, wherein, the rotation arm is connected to the slide base to be rotated in accordance with the movement of the slide base.
  • the rotation arm since the rotation arm is connected to the slide base, the rotation arm certainly rotates even if the door is not excessively rigid. Furthermore, since the warping of the door is negligible, the rotation arm certainly rotates even if a connecting member for the connection with the door driver is provided at the anterior door end side of the door. Therefore, the components such as the door driver and the connecting member for the connection with the door are provided in a narrow area in the front-back directions of the vehicle. This ensures the downsizing of the plug door apparatus.
  • the above-described plug door apparatus is preferably arranged to include as the rotation arm, a lower rotation arm which is connected to the upper rotation arm connected to the upper part of the door and is also connected to the lower part of the door, wherein the rotation axis of the upper rotation arm is connected to the rotation axis of the lower rotation arm.
  • one of the upper rotation arm and the lower rotation arm is certainly rotated by rotating the remaining one of them.
  • the opening, closing, and plugging are carried out by the door driver which applies a force to the door in a front-back direction of the vehicle, and also the plug door apparatus is downsized.
  • full-closed state a state in which doors 104a and 104b are fully closed
  • full-opened state a state in which the doors are fully opened
  • full-opened position a position of each component in the full-closed state
  • full-opened position a position of each component in the full-opened state
  • a vehicle side wall 101 is provided with an entrance 102 (whose width will be referred to as S1). Above the entrance 102 is fixed a frame 103 which extends in the front-back directions. It is noted that the "front-back directions" are directions in parallel to the traveling direction of the vehicle and are indicated by the arrows A in Fig. 1 . In Fig. 1 , the direction toward the right side of the figure is the direction toward the front side of the vehicle, whereas the direction toward the left side of the figure is the direction toward the rear side of the vehicle.
  • a pair of doors 104a and 104b are provided to cover the entrance 102.
  • the doors 104a and 104b constitute a double door, and are opened and closed by a plug door apparatus 1.
  • the doors 104a and 104b are arranged to substantially seal the entrance 102 in the full-closed state.
  • the plug door apparatus 1 includes a fixed base 2 fixed to the main body of the vehicle, a slide base 3 provided on the fixed base 2, a door driver 4 by which the doors 104 are driven, axis components 5a and 5b moved in the front-back directions of the vehicle by the door driver 4, and guide portions 6a and 6b guiding the axis components 5a and 5b.
  • the fixed base 2 is fixed to the connecting plate members 103c and 103d.
  • the fixed base 2 is fixed so as not to move relative to the frame 103 (vehicle main body).
  • the fixed base 2 is arranged so that the straight edge portion on the outer side in the vehicle width direction is in parallel to the front-back directions of the vehicle. It is noted that on the edge portion of the fixed base 2 on the outer side in the vehicle width direction are formed recesses 2a and 2b curving toward the inner side in the vehicle width direction (see Fig. 5(b) ).
  • the "vehicle width direction" above is the directions orthogonal to both the front-back directions of the vehicle and the vertical directions, and are indicated by the arrows B in Fig. 3 , Fig. 5 , or the like.
  • the right side of the figure is the inner side of the vehicle whereas the left side of the figure is the outer side of the vehicle.
  • the slide base 3 is arranged to include a plate member which is substantially L-shaped in cross section taken along a line orthogonal to the front-back directions of the vehicle.
  • This plate member is constituted by a bottom plate portion 32 extending substantially in horizontal directions and a back plate portion 33 extending substantially in vertical directions.
  • the slide base 3 is symmetrically shaped in the front-back directions of the vehicle.
  • the bottom plate portion 32 of the slide base 3 is provided with grooves 32a and 32b (groove portions) extending in parallel to the front-back directions of the vehicle. These grooves 32a and 32b penetrate the bottom plate portion 32.
  • the slide base 3 is provided above the fixed base 2 via linear guides 31 which are in parallel to the vehicle width direction.
  • the three linear guides 31 are provided at around the both edges of the fixed base 2 and at around the central part of the fixed base 2 in the front-back directions of the vehicle.
  • each of the linear guides 31 is provided with a rail 31a fixed to the upper surface of the fixed base 2 and extending in the vehicle width direction and a sliding member 31b slidable along the rail 31a.
  • the sliding member 31b is fixed to the lower surface of the bottom plate portion 32 of the slide base 3.
  • the slide base 3 is therefore movable in the vehicle width direction relative to the fixed base 2.
  • the movement of the slide base 3 toward the inner side in the vehicle width direction is stopped when the slide base 3 contacts a stopper 21 of the fixed base 2.
  • the movement of the slide base 3 toward the outer side in the vehicle width direction is stopped when the slide base 3 contacts a stopper 22 of the sliding member 31b.
  • a main body 41 of the door driver 4 is fixed to the back plate portion 33 of the slide base 3.
  • a pair of racks 42a and 42b extend from the main body 41 in the front-back directions of the vehicle.
  • the main body 41 is provided with an unillustrated electric motor which is a direct drive motor rotatable forward and backward. As the motor is driven, a pinion 42c engaged with the pair of racks 42a and 42b is rotated via a planetary gear mechanism G, with the result that the racks 42a and 42b move in opposite directions, respectively.
  • the racks 42a and 42b are connected to first brackets 43a and 43b (connecting members) at the leading ends, respectively.
  • the first brackets 43a and 43b are further connected to second brackets 44a and 44b and rail pinions 46a and 46b of double-speed rails 45a and 45b, respectively.
