Description

  The present invention relates to an automatic opening / closing device for a vehicle that automatically opens and closes a sliding door provided in the vehicle.

  A slide door is provided on a side portion of a vehicle such as a wagon car or a one-box car in order to open and close an opening for getting on and off. Such a slide door is provided with a support arm, and on the other hand, a guide rail extending in the vehicle front-rear direction is fixed to the side of the vehicle body, and the slide door slides in the vehicle front-rear direction by being guided by the guide rail. It opens and closes in a formula. In addition, a curved portion that bends toward the vehicle interior side is provided on the closed side (front side of the vehicle) of the guide rail, and the slide door is located on the vehicle interior side by guiding the support arm to the curved portion. It is pulled in and closed to be flush with the side of the car body.

  In order to facilitate the opening and closing operation of the sliding door, an automatic opening and closing device for a vehicle has been developed that automatically opens and closes the sliding door by a drive source such as an electric motor. As such an automatic opening / closing device, a roller unit is provided with a driving unit (driving means) having a pair of open and closed cables coupled to the roller assembly from the opening / closing direction (vehicle longitudinal direction) and an electric motor as a driving source, There is a cable type in which each cable is driven by a drive unit so that the sliding door is pulled by the cable and automatically opened and closed.

  By the way, when the sliding door is fully closed, a door seal material is provided on one side of the portion where the sliding door and the vehicle body face each other to prevent rainwater from entering the vehicle interior when the sliding door is fully closed. It is arranged so that it can be elastically contacted with the other side when fully closed. For this reason, when the sliding door is closed to the half-door position and further pulled to the fully-closed position, a force that deforms (or compresses) the sealing material is required, and the sliding door is half-powered by the force of the drive unit alone. It may be difficult to pull in from the door position (below a predetermined opening) to the fully closed position.

Therefore, for example, in the automatic opening / closing device disclosed in Patent Document 1, a closer mechanism for pull-in operation is separately provided in addition to a drive unit for automatically opening and closing the sliding door, and the sliding door closed to the half door position is provided. It is driven by a closer mechanism and pulled to the fully closed position.

That is, the latch 53 is connected to the motor unit 32 by the latch connection link 62, whereby the motor unit 32 has a first rotation direction and a second rotation direction to be described later with respect to the slide door 14 with the support shaft 37 as an axis. The latch 53 rotates between the unlatched position and the full latched position in conjunction with the rotation.

  The base plate 38 is covered with a cover 39 (detailed outer shape is omitted), and a latch 53, a ratchet 56, a disk member 72 described later, and the like are disposed therein. The pin member 61 is movable along an arc groove 39a provided in the cover 39, and the rotation range of the latch 53 is defined by the arc groove 39a. When the latch 53 is in the unlatched position, the pin member 61 is located at the unlatched end 39b (the right end of the arc groove 39a in FIG. 6), which is the initial position of the arc groove 39a. In this state, the pin members 61 and 63 are arranged so as to have a predetermined positional relationship with respect to the latch shaft 54. As a result, when the slide door 14 is opened to a predetermined opening or more, the latch connection link 62 and the pin members 61 and 63 are applied with the traction force of the closed cable 25b driven by the motor unit 32 to the motor unit 32. Even when the motor unit 32 is restricted from rotating in the first rotational direction (the direction in which the latch 53 is rotated from the unlatched position to the full latched position), and when the slide door 14 is closed to a predetermined opening degree, It also functions as switching means for releasing the restriction and rotating the motor unit 32 in the first rotation direction.

  Hereinafter, the positional relationship of the pin members 61 and 63 with respect to the latch shaft 54 and the switching operation by the latch connection link 62 will be described.

  FIGS. 7A and 7B are explanatory views showing the switching operation of the connecting links, and FIGS. 8A to 8C are respectively driven from the half latch position to the full latch position by the traction force of the closed cable. It is explanatory drawing which shows the state performed.

  When the slide door 14 is opened more than a predetermined opening and the latch 53 is in the unlatched position, as shown in FIG. 7A, the pin member 61 that connects the latch 53 and the latch connection link 62 is provided. The axis is on the unlatch side (latch line) with respect to the straight line L (virtual line) connecting the rotation center of the latch 53, that is, the axis of the latch shaft 54 and the axis of the pin member 63 connecting the motor unit 32 and the latch connection link 62. 53 is located at the initial position (in the direction of rotation from the full latch position toward the unlatched position) and is in contact with the unlatched end 39b of the arc groove 39a. Accordingly, the electric motor 34 is driven to rotate, the drum 42 is rotated in the second rotation direction opposite to the first rotation direction, the closed cable 25b is pulled, and the motor unit 32 is pulled by the traction force (tension). Even if a rotational force in the first rotational direction with the support shaft 37 as the center is applied, the rotational force of the pin member 61 is restricted by the unlatched end 39b of the arc groove 39a. Rotation, that is, rotation about the support shaft 37 of the motor unit 32 is also restricted. That is, when the slide door 14 is opened more than a predetermined opening, the latch connection link 62 having a function as a switching means causes the first rotation centering on the support shaft 37 of the motor unit 32 by the pulling force of the closed cable 25b. 1 is restricted from rotating in the rotation direction. Therefore, when the electric motor 34 is rotationally driven in this state to rotate the drum 42 in the second rotational direction and pull the closed cable 25b, the slide door 14 can be moved toward the closed side.

  As described above, even when the sliding door 14 is opened more than the predetermined opening degree, even if the closing side of the open / close switch is operated and the electric motor 34 is operated and the closing cable 25b is driven by the motor unit 32, the motor unit. 32 can drive the closed cable 25b and close the slide door 14 without rotating in the first rotation direction with the support shaft 37 as an axis.

  When the sliding door 14 is automatically closed and closed to a predetermined opening (half-door position), the latch 53 engages with the striker 58 and is pushed by the striker 58 from the unlatched position as shown in FIG. It rotates counterclockwise in the figure to the release position.

  When the latch 53 rotates to the release position, the pin member 61 that connects the latch 53 and the latch connection link 62 moves in the arc groove 39a toward the full latch end 39c, and the axis of the pin member 61 is also the rotation center of the latch 53, that is, More than the straight line L (virtual line) connecting the axis of the latch shaft 54 and the axis of the pin member 63 connecting the motor unit 32 and the latch connection link 62 (the latch 53 is directed from the unlatched position toward the full latched position). Move to the direction of rotation). Therefore, when the rotational force that rotates the motor unit 32 in the first rotational direction about the support shaft 37 is applied to the motor unit 32 by the traction force of the closed cable 25b, the rotational force is connected to the case 35a. It acts on the pin member 63 of the latch connection link 62 from the end of the long hole 64 and acts on the latch 53 via the latch connection link 62 in the direction of rotating the latch 53 in the full latch direction. At this time, the door seal member 14 a of the slide door 14 is in contact with the vehicle body 12, and the closing operation of the slide door 14 by the drive unit 31 is temporarily stopped or decelerated by the elastic force. When the drum 42 is rotated in the second rotational direction by the rotational driving force (traction force), the drum 42 cannot be rotated, and the rotational driving force (traction force) rotates the motor unit 32 itself in the first rotation direction. Driving force. In other words, when the slide door 14 is closed to a predetermined opening, the motor unit 32 can be rotated in the first rotational direction by the pulling force of the closed cable 25b by the latch connection link 62 having a function as a switching means. Can be switched. The motor unit 32 is pulled by the closed cable 25b and rotates in the first rotation direction, that is, the lock direction, and drives the latch 53 toward the full latch position.

  Thus, when the slide door 14 is closed more than the predetermined opening, the latch 53 is driven by the motor unit 32 that rotates in the first rotation direction with the support shaft 37 as an axis, and rotates toward the full latch position. .

  When the latch 53 is driven by the rotation of the motor unit 32 and rotates toward the full latch position, the engagement between the latch 53 and the striker 58 gradually deepens as shown in FIGS. The door 14 is pulled toward the fully closed position as the latch 53 and the striker 58 move relative to each other. Then, as shown in FIG. 8C, when the motor unit 32 reaches the stroke end in the first rotation direction and the latch 53 rotates to the full latch position, the slide door 14 is fully closed, and the closer mechanism 51 The pull-in operation ends. At this time, the latching claw portion 56a of the ratchet 56 is engaged with the latch groove 53a of the latch 53, and the slide door 14 is held in the fully closed position. At the same time, the pin member 61 reaches the full latch end 39c of the arc groove 39a. The control device 40 outputs a rotation stop signal to the electric motor 34 when detecting that the locking claw portion 56 a of the ratchet 56 is engaged with the latch groove 53 a of the latch 53.

  As described above, when the slide door 14 is closed to a predetermined opening degree, the motor unit 32 itself rotates by the pulling force of the closed cable 25b, and the latch 53 is driven toward the full latch position by this rotation operation, and the slide door. 14 is pulled to the fully closed position.

  Since the drum 42 is substantially stopped during the rotation of the motor unit 32 itself, the open side cable 25a and the closed side cable 25b do not sag, but the connecting units 26a and 26b serve as tensioners. Therefore, the looseness of the cables 25a and 25b due to the slight rotation of the drum 42 accompanying the rotation of the motor unit 32 itself is absorbed by the tensioner function of the connecting units 26a and 26b, and this opening / closing device. 24 can be operated reliably.

  As described above, in the opening / closing device 24, when the slide door 14 is closed to a predetermined opening, the motor unit 32 is rotated about the support shaft 37 by the traction force of the closed cable 25b. Since the latch 53 is driven toward the full latch position by the rotation operation of itself 32, the power of the electric motor 34 for driving the cable is used without providing the electric motor or the driving mechanism for the closer mechanism 51. The slide door 14 closed to a predetermined opening can be pulled into the fully closed position. Therefore, the closer mechanism 51 can be reduced in size, and the mountability of the opening / closing device 24 on the vehicle body 12 can be improved.

  Further, in this opening / closing device 24, when the latch 53 is in the unlatched position, the pin member 61 is disposed at the lock position (initial position) in the unlatching direction of the latch 53 with respect to the straight line L connecting the latch shaft 54 and the pin member 63. Then, the rotation operation of the motor unit 32 due to the traction force of the closed cable 25b is restricted, and when the latch 53 is rotated to the release position, the pin member 61 is latched with respect to the straight line L connecting the latch shaft 54 and the pin member 63. Since the motor unit 32 is switched to a state in which the motor unit 32 can be rotated by the pulling force of the closing cable 25b by being arranged in the full latch direction 53, the sliding door 14 is switched from the normal automatic closing operation to the retracting operation by the closer mechanism 51. The configuration of the switching means for reducing the cost of the switchgear 24 is simplified. It is possible.

  On the other hand, as shown in FIG. 6, the drive unit 31 is provided with a releaser mechanism 71. When the slide door 14 is automatically opened from the fully closed position, the releaser mechanism 71 causes the ratchet 56 to be released from the holding position. The latch 53 is released from being held by the ratchet 56.

  The releaser mechanism 71 has a disc member 72 formed in a disc shape from a steel plate or the like. The disc member 72 is rotatably supported on the base plate 38 by a releaser shaft 73 and is in sliding contact with the outer peripheral surface of the ratchet 56 on the outer peripheral surface thereof.

  The outer peripheral surface of the ratchet 56 that is in sliding contact with the disk member 72 is formed in an arc shape so that the swinging of the ratchet 56 is not restricted even if the disk member 72 is in sliding contact. A stopper surface 56b provided substantially perpendicularly to the outer peripheral surface is provided on one end side of the arc-shaped outer peripheral surface 56.

  The disk member 72 is formed with a groove 72a so as to open to the outer peripheral surface thereof, and a stopper 74 as a claw member is movable in the radial direction of the groove 72a, that is, can be moved forward and backward. Contained. Further, a spring 75 as a spring member is accommodated in the groove portion 72a, and the stopper 74 is urged by the spring 75 in a protruding direction (a direction protruding outward from the groove portion 72a). Although not shown in detail, the stopper 74 is held inside the groove portion 72a by a holding portion (not shown) and is not detached from the groove portion 72a.

  The disc member 72 is provided with a pin member 76 that is separated from the axial center of the releaser shaft 73 by a predetermined distance in the radial direction and parallel to the releaser shaft 73, and the pin member 76 has a connection hole 77 a at one end of the releaser connection link 77. Are rotatably connected. Further, a pin member 78 is provided at the other end of the releaser connecting link 77 in parallel with the pin member 76, and this pin member 78 is predetermined from the output shaft 36 of the case 35 a of the motor unit 32, that is, the axis of the support shaft 37. It is rotatably connected to a connecting hole 65 provided in the radial direction by a distance. That is, the disk member 72 is connected to the motor unit 32, and when the motor unit 32 rotates in the first rotational direction with respect to the slide door 14 about the support shaft 37 by the traction force of the closed cable 25b, As shown in FIGS. 8 (a) and 8 (b), the disk member 72 rotates in the direction in which the stopper 74 approaches the ratchet 56 (clockwise direction in FIG. 8) in conjunction with the rotation. When the motor unit 32 rotates to the stroke end in the first rotation direction and the latching claw portion 56a of the ratchet 56 is engaged with the latch groove 53a of the latch 53, the disk member 72 is shown in FIG. The stopper 74 is engaged with the stopper surface 56 b beyond the outer peripheral surface of the ratchet 56. That is, when the motor unit 32 rotates to the stroke end in the first rotation direction, the stopper 74 of the releaser mechanism 71 is engaged with the ratchet 56 at the holding position.

  FIGS. 9A to 9C are explanatory views showing a procedure in which the releaser mechanism releases the ratchet by the pulling force of the open cable.

  Next, the release operation of the ratchet 56 by the releaser mechanism 71 will be described with reference to FIG.

  As shown in FIG. 9A, the slide door 14 is fully closed, the latch 53 is in the fully latched position, and the latch groove 53a of the latch 53 is engaged with the latching claw 56a of the ratchet 56. When the opening side of the opening / closing switch (not shown) is operated when the position is in the position, the drive unit 31 is driven by the traction force of the opening side cable 25a of the electric motor 34 so that the motor unit 32 has the second rotational direction ( The latch 53 is rotated in the direction in which the latch 53 is rotated toward the unlatched position.

  When the motor unit 32 itself rotates in the second rotational direction by the pulling force of the open cable 25a, the disc member 72 of the releaser mechanism 71 is interlocked with the motor unit 32 as shown in FIG. Rotate clockwise. As a result, the ratchet 56 is driven by the stopper 74 whose stopper surface 56b rotates together with the disk member 72 and is driven from the holding position toward the release position, and the engagement with the latch 53 is released. That is, when the motor unit 32 itself rotates in the second rotation direction, the releaser mechanism 71 is operated by the rotation, and the ratchet 56 is driven from the holding position to the release position.

  Further, when the releaser mechanism 71 releases the ratchet 56, the latch connection link 62 moves the pin member 63 of the motor unit 32 away from the pin member 61 side inside the connection long hole 64. As a result, when the releaser mechanism 71 releases the ratchet 56, the latch 53 does not move toward the unlatched position, but waits at the full latched position while allowing the motor unit 32 itself to rotate in the second rotational direction. Is done. When the ratchet 56 is driven to the release position by being driven by the releaser mechanism 71 and the engagement between the latch groove 53a of the latch 53 and the locking claw 56a of the ratchet 56 is released, as shown in FIG. 9B. The pin member 63 reaches the end of the long hole 64 of the latch connection link 62 on the pin member 61 side, the latch connection link 62 is driven by the motor unit 32, and the latch 53 is interlocked with the rotation of the motor unit 32 itself. Thus, an urging force by a return spring (not shown) is also applied to rotate from the full latch position toward the unlatch position. When the motor unit 32 itself rotates to the initial position shown in FIG. 9C, the latch 53 reaches the unlatched position, and the rotation of the motor unit 32 itself in the second rotation direction is restricted. When the rotation of the motor unit 32 itself is restricted, the rotational driving force in the second rotational direction by the electric motor 34 becomes a rotational driving force (traction force) that rotates the drum 42 in the first rotational direction. Then, the open side cable 25a is driven, and the roller assembly 21 supported by the lower rail 17 is pulled by the open side cable 25a to automatically open the slide door 14. At this time, since the pin member 61 returns to the unlatched end 39b, which is the initial position of the arc groove 39a, preparation for the next closing operation of the slide door 14 is made.

  Thus, in the opening / closing device 24, when the slide door 14 is automatically opened by being driven by the drive unit 31, the releaser mechanism 71 is operated by using the rotation of the motor unit 32 by the pulling force of the open cable 25a as power. Since the engagement of the ratchet 56 with the latch 53 is released, the lock of the latch 53 by the ratchet 56 can be released using the motor unit 32 for automatically opening and closing the slide door 14. In other words, in the opening / closing device 24, the closer mechanism 51 is operated by the rotation of the motor unit 32 itself in the first rotation direction to retract the slide door 14, and the motor unit 32 itself moves in the second rotation direction. The releaser mechanism 71 can be operated by rotation to release the ratchet 56. As a result, the slide door 14 is automatically opened and closed by the single motor unit 32, the retracting operation to the fully closed position, and the ratchet 56 without providing a separate drive means such as an electric motor for the closer mechanism 51 and the releaser mechanism 71. Can be released. Therefore, the releaser mechanism 71 can be reduced in size, and the mountability of the opening / closing device 24 on the vehicle 11 can be improved.

  Further, in this opening / closing device 24, the releaser mechanism 71 is constituted by a disc member 72 that is in sliding contact with the ratchet 56 on the outer peripheral surface, and a stopper 74 that is housed in a groove portion 72a that opens in the outer peripheral surface of the disc member 72 so as to be movable forward and backward. Since the stopper 74 is engaged with the ratchet 56 when the motor unit 32 rotates to the stroke end in the first rotation direction, the configuration of the releaser mechanism 71 is simplified and the motor unit 32 itself The release operation of the ratchet 56 by the releaser mechanism 71 can be started simultaneously with the start of the rotation in the first rotation direction.

  Further, in the opening / closing device 24, the pin member 63 provided at one end of the latch connection link 62 is supported by the long hole 64 provided in the case 35a of the motor unit 32, so that the motor unit 32 has a stroke in the first rotational direction. When rotating from the end in the second rotation direction, the latch 53 can be rotated toward the unlatched position after the releaser mechanism 71 releases the engagement of the ratchet 56 with the latch 53. Accordingly, the release operation of the ratchet 56 by the releaser mechanism 71 and the rotation of the latch 53 in the unlatched position direction can be performed smoothly.

  FIGS. 10A to 10C are front views showing modifications of the releaser mechanism shown in FIG. 6, and the releaser mechanism 71 is not limited to the one using the disk member 72, but as shown in FIG. The releaser lever 81 may be used.

  In this case, the releaser lever 81 has an arc-shaped contact surface 81a, and the contact surface 81a is always in contact with the ratchet 56. A long hole 82 is provided in the case 35 a of the motor unit 32, and a pin member 78 provided at one end of the releaser connecting link 77 is supported by the motor unit 32 in the long hole 82. Accordingly, as shown in FIGS. 10A and 10B, when the latch 53 rotates toward the full latch position in conjunction with the motor unit 32, the pin member 78 moves through the long hole 82. The releaser mechanism 71 does not operate.

  On the other hand, when the sliding door 14 is automatically opened by the drive unit 31, even if the motor unit 32 starts to rotate in the second rotational direction from the position shown in FIG. While moving the long holes 64 and 82, neither the latch 53 nor the releaser mechanism 71 operates, and when the motor unit 32 rotates to the position shown in FIG. 10A, the pin members 63 and 82 are driven to the motor unit 32. Then, as shown in FIG. 10C, the release mechanism 71 releases the ratchet 56 and the latch 53 is driven toward the unlatched position.
