Description

  The present invention relates to an intermediate stopper mechanism in a vehicle that restricts a sliding operation in an opening direction of a sliding door at a predetermined position when a window glass of the sliding door is opened beyond a predetermined opening degree.

As a prior art of an intermediate stopper mechanism for a sliding door in a vehicle, for example, there is one disclosed in Patent Document 1.
In the vehicle of Patent Document 1, a door opening is formed on the side surface of the vehicle body, and a lower rail is provided on the bottom surface of the door opening. A lower roller of a lower arm that supports the lower end portion of the slide door is slidably engaged with the lower rail.
In addition, one end of the operating lever is pivotally attached to the lower end of the sliding door, and the operating lever can rotate between a standby position stored on the sliding door side and an operating position protruding from the sliding door to the inside of the vehicle. It is. The operating lever is positioned at the standby position when the opening degree of the window glass provided on the slide door is equal to or smaller than the predetermined opening degree, and rotates to the operating position when the window glass is opened beyond the predetermined opening degree. When the sliding door is slid in the opening direction with the window glass of the sliding door exceeding the predetermined opening (the operating lever protrudes to the operating position), the operating lever hits the intermediate stopper provided on the bottom of the door opening. Therefore, sliding of the sliding door in the opening direction is restricted.
JP 2006-35929 A

Since the sliding door is a heavy member, it is necessary to increase the mechanical strength of the operating lever in order to stop the sliding door in the opening direction.
However, if the thickness of the actuating lever is increased in order to increase the mechanical strength of the actuating lever, the weight of the actuating lever increases. As a result, a large force is required to slide the sliding door. If an expensive material is used, it is not necessary to increase the plate thickness of the operating lever, but in this case, the manufacturing cost increases.

Furthermore, since the operating lever is pivotally attached to the slide door in a cantilever state, the mechanical lever is also required to have a high mechanical strength.
However, in order to increase the mechanical strength of the pivot attachment mechanism, the members constituting the pivot attachment mechanism must be enlarged, or the members constituting the pivot attachment mechanism must be formed of an expensive material. Therefore, a problem similar to that in the case of attempting to increase the mechanical strength of the actuating lever also occurs with respect to the pivot mechanism.

  The object of the present invention is to make it possible to reliably stop sliding in the opening direction of a sliding door at a predetermined position while the manufacturing cost is low, and to slide the sliding door with the same level of force as before. An object is to provide an intermediate stopper mechanism in a vehicle.

  An intermediate stopper mechanism in a vehicle according to the present invention includes a door support arm that is slidably engaged with a slide rail provided on a vehicle body and supports the slide door, and a slide door provided on the slide door or the door support arm. When the opening degree of the window glass is less than or equal to the predetermined opening degree, it is located at the non-pressing position, and when the opening degree of the window glass exceeds the predetermined opening degree, the pressing member is located at the pressing position, In addition, the pressing member positioned at the pressing position is located at the non-operating position that does not interfere with the pressing member positioned at the non-pressing position and can interfere with the pressing member positioned at the pressing position. A stopper operating member that moves to an operating position when pressed, and the door support arm provided on the vehicle body when the stopper operating member is positioned at the non-operating position. And a stopper that moves to an interference position on the movement locus of the door support arm when the stopper operation member moves to the operation position. .

  The door support arm is a lower arm that engages with the slide rail provided at the bottom of the door opening and supports the lower end of the slide door, and the stopper operating member and the stopper are placed on the bottom of the door opening. It is preferable to provide it.

  The stopper actuating member is rotatable with respect to the vehicle body between the non-actuated position and the actuated position, and is always urged to rotate to the non-actuated position side by the rotation urging means. Between the interference position and the non-interference position is rotatable with respect to the vehicle body, and engages with a long hole formed in one of the stopper operating member and the stopper and the long hole formed in the other. It is preferable that the mating pin constitutes an interlocking mechanism between the stopper operating member and the stopper.

  When the fuel lid that opens and closes the fuel lid opening formed behind the door opening on the side surface of the vehicle body is in the closed position, and when the stopper operating member is in the non-operating position and the fuel lid is in the open position It is preferable that a fuel lid interlocking mechanism for positioning the stopper operating member at the operating position is provided.

According to the first aspect of the present invention, the door support arm is a member that slidably supports the slide door with respect to the vehicle body, and thus is generally a member having high mechanical strength, and is also supported by both the slide rail and the slide door. Yes. In this invention, since this door support arm is made to contact | abut to a stopper, it is possible to stop reliably the sliding door which the window glass opened exceeding the predetermined opening degree.
The pressing member provided on the sliding door or the door support arm does not stop the sliding of the sliding door by coming into contact with the stopper, but is a member for operating the stopper operating member on the vehicle body side. Therefore, the mechanical strength required for the pressing member is considerably smaller than that of the door support arm. Therefore, since it is not necessary to increase the plate thickness of the pressing member, the total weight of the sliding door, the door support arm and the pressing member does not increase (the sliding door can be slid with the same level of force as before). . Further, since the pressing member does not need to be formed from an expensive material, it can be manufactured at a low cost.
Further, no great mechanical strength is required for the support structure between the pressing member and the slide door or the door support arm. Therefore, the support structure can also be manufactured at a low cost.

  According to the second aspect of the present invention, the bottom portion of the door opening is a portion that increases the rigidity of the body, so that the mechanical strength is designed to be high. When the stopper actuating member and the stopper are provided at a place where the mechanical strength is high as described above, the support strength between the stopper and the vehicle body (the bottom of the door opening) is improved as compared with the case where the stopper operating member and the stopper are provided at other places. Therefore, the sliding door can be stopped more reliably.

  If comprised like Claim 3, the mechanical interlocking mechanism of a stopper action member and a stopper can be comprised easily.

  According to the fourth aspect, when the fuel lid is open, the sliding door can be prevented from sliding in the opening direction toward the fuel lid and contacting the fuel lid by using the intermediate stopper mechanism. Therefore, the stopper mechanism for preventing collision of the fuel lid can be provided as an inexpensive and simple structure as compared with the case where the stopper mechanism for preventing collision of the fuel lid is provided as completely separate from the intermediate stopper mechanism.

Hereinafter, an embodiment of the present invention will be described with reference to the accompanying drawings. In the following description, the front-rear direction and the left-right direction are based on the arrow direction in the figure.
A rectangular door opening 12 is formed in the outer wall 11 of the vehicle body 10 in a side view. An upper rail (not shown) extending in the front-rear direction is provided on the ceiling of the door opening 12, and a lower rail (slide rail) 14 extending in the front-rear direction is provided on the bottom of the door opening 12. A roller provided at the inner end of the upper arm 15 is rotatably fitted to the upper rail, and a rotation support shaft 17 is provided on the lower rail 14 so as to project from the inner end of the upper surface of the lower arm (door support arm) 16. A sliding roller 18 that can rotate around is fitted so as to be rotatable (slidable on both side surfaces of the lower rail 14). The vehicle outer end portion of the upper arm 15 is fixed to the upper end portion of the slide door 20 having the same side shape as the door opening 12, and the vehicle outer end portion of the lower arm 16 is fixed to the lower end portion of the slide door 20. Thus, since the upper and lower ends of the slide door 20 are slidably supported by the upper arm 15 and the lower arm 16 with respect to the upper rail and the lower rail 14, the slide door 20 completely closes the door opening 12 and the door opening. It is possible to slide between the fully open position where 12 is fully opened.
As shown in FIG. 1, a locking striker 22 projects rearward from the front end surface of the door opening 12, and locks when the sliding door 20 is positioned at the fully closed position on the front end surface of the sliding door 20. A lock device 23 for locking the striker 22 is provided. As is well known, the locking device 23 shifts from the locked state to the unlocked state by rotating the outer handle 24 or the inner handle 25 provided on the slide door 20, so that the slide door 20 positioned at the fully closed position is moved. If the outer handle 24 or the inner handle 25 is rotated while the locking device 23 is locking the locking striker 22, the locking striker 22 and the locking device 23 are unlocked, and the sliding door 20 is moved in the opening direction. Slide becomes possible.
As shown in FIG. 1, a rectangular window hole 26 is formed in the upper part of the slide door 20 in a side view, and a window glass 27 slidable in the vertical direction is provided inside the slide door 20. The window glass 27 is linked to a known window regulator (not shown) provided inside the slide door 20, and this window regulator is connected to a window opening / closing motor (not shown) provided in the slide door 20. ing. When the window opening / closing motor rotates by operating a glass opening / closing switch (not shown) provided in the vehicle, the window regulator is operated by the driving force of the window opening / closing motor, and the window glass 27 completely closes the window hole 26. Slide between the fully closed position and the fully open position where the window glass 27 is completely opened.

As shown in FIGS. 2 and 3, the horizontal piece 28 of the pressing member 30 including the horizontal piece 28 and the vertical piece 29 orthogonal to each other is rotated in the vertical direction in the vicinity of the vehicle outer end on the lower surface of the lower arm 16. A support shaft 31 is pivotally mounted so as to be rotatable. As shown in FIG. 2, one end of the operation wire W <b> 1 is fixed to the pressing member 30, and the other end of the operation wire W <b> 1 passes through a through hole 32 formed near the lower end portion of the slide door 20. 20 extends further upward and is connected to the window regulator (not shown, but the peripheral surface of the operation wire W1 is covered with an outer tube).
Thus, since the window glass 27 and the pressing member 30 are linked via the operation wire W1, the rotational position of the pressing member 30 changes according to the position of the window glass 27. That is, when the opening degree of the window glass 27 is equal to or less than a predetermined opening degree set in advance (for example, when the window member 27 is located at the fully closed position), the pressing member 30 is not pressed (not shown) by the urging means (not shown). 4 and the position of FIG. 6) (rotation biased). On the other hand, when the opening degree of the window glass 27 exceeds a predetermined opening degree set in advance (for example, when the window glass 27 moves to the fully opened position), the operation wire W1 is pulled in conjunction with the operation of the window regulator, and the pressing member 30 is It rotates to the pressing position (the position of FIG. 2, the position of the two-dot chain line of FIG. 3, the position of FIG. 5).

As shown in FIGS. 2 to 5, the bottom plate 37 of the door opening 12 (located below the lower rail 14) has a rectangular through hole 38 that is rectangular in plan view.
A storage space 39 is formed in the lower end portion of the vehicle body 10 (a portion located below the bottom plate 37). In this storage space 39, three rotating members, that is, a stopper operating member 40 and a fuel lid interlocked in order from the vehicle exterior side. A lever 50 and a stopper 60 are provided.
As shown in FIGS. 3 to 6, both end portions of the rotation support shaft 41 and the rotation support shaft 51 extending in the vehicle width direction are fixed to the left and right side walls in the storage space 39.
The stopper operating member 40 is a member whose front end portion is pivotally attached to the rotation support shaft 41. The stopper operating member 40 includes a non-operating position where the stopper surface 42 formed on the upper surface of the rear end portion abuts on the lower surface of the bottom plate 37 (the position in FIG. 4 and the position of the imaginary line in FIGS. 5 and 6), and the stopper surface. It is possible to rotate between operating positions (solid line positions in FIGS. 5 and 6) where 42 is moved downward from the bottom plate 37, and in any position, it is positioned below the lower arm 16 (does not interfere with the lower arm 16). ). A coil portion of a torsion coil spring (rotation urging means, not shown) whose both ends are respectively locked between the bottom plate 37 and the stopper operating member 40 is wound around the rotation support shaft 41. The stopper actuating member 40 is always urged to rotate to the non-actuated position side by the rotation urging force. The front half of the stopper actuating member 40 is a pressed portion 43 having a substantially fan shape in side view, and the rear end portion of the upper surface of the pressed portion 43 is a pressed plane 44. Further, a long hole 45 extending in the front-rear direction is formed as a through hole in the rear end portion of the stopper operating member 40.
The fuel lid interlocking lever 50 (fuel lid interlocking mechanism) is a member that is rotatably supported by the rotation support shaft 51. The fuel lid interlocking lever 50 is a substantially U-shaped member having a base portion 52 and a pressing portion 53 narrower than the base portion 52, and is rotated counterclockwise in FIG. 4 by a biasing means (not shown). It is energized. A locking hole 54 is formed in the vicinity of the distal end portion of the base 52, and the front end portion of the linkage rod 70 (fuel lid interlocking mechanism) (linking member) is locked in the locking hole 54. The rear end portion of the linkage rod 70 is engaged with a fuel lid 76 that opens and closes a rectangular fuel lid opening 75 drilled rearward from the door opening 12 of the outer wall 11 of the vehicle body 10. The operation and the rotation operation of the fuel lid interlocking lever 50 are interlocked. Specifically, when the fuel lid 76 is located at the closed position (the position shown in FIG. 1) that closes the fuel lid opening 75, the fuel lid interlocking lever 50 is located at the non-operation position shown in FIG. 4, and the fuel lid 76 opens the fuel lid opening 75. When located at the open position (not shown) for opening, the fuel lid interlocking lever 50 is located at the operation position shown in FIG. 6 (position where the base 52 contacts the rear end face of the rectangular through hole 38).
The stopper 60 is a member that is rotatably supported by the rotation support shaft 51 on which the fuel lid interlocking lever 50 is supported. A pressed surface 61 is formed on the outer peripheral surface of the stopper 60. Further, an engagement pin 62 is provided on the outer surface of the stopper 60 so as to be engaged with the elongated hole 45 of the stopper operating member 40 so as to be relatively movable and to come into contact with the lower surface of the pressing portion 53. Thus, since the engaging pin 62 is engaged with the long hole 45, the rotation operation of the stopper operating member 40 and the rotation operation of the fuel lid interlocking lever 50 are interlocked. Specifically, when the stopper operating member 40 is located at the non-actuated position, the stopper 60 is located at a non-interference position (the position shown in FIG. 4 and the position of the imaginary line in FIGS. 5 and 6) that does not protrude above the bottom plate 37. When the stopper operating member 40 is positioned at the operating position, the stopper 60 is positioned at the interference position (the position in FIGS. 5 and 6) where the pressed surface 61 protrudes above the bottom plate 37 and the pressed surface 61 is substantially vertical. To do.
Among the components described above, the lower arm 16, the pressing member 30, the stopper operating member 40, the stopper 60, and the operation wire W1 are components of the intermediate stopper mechanism, and the lower arm 16, the stopper operating member 40, the fuel lid interlocking lever 50, The stopper 60 and the linkage rod 70 are components of a stopper mechanism for preventing fuel lid collision.

Next, the operation of this embodiment will be described. Since the operation of the present embodiment can be divided into two cases when the sliding door 20 is slid in the opening direction and when the fuel lid 76 is opened and closed, the following description will be divided into these two cases.
(Operation when sliding the sliding door 20 in the opening direction)
In this case, the operation differs depending on the position of the window glass 27.
When the opening degree of the window glass 27 is equal to or less than the predetermined opening degree as in the fully closed position, the pressing member 30 is located in the non-pressing position as described above. Thus, when the pressing member 30 is located at the non-pressing position, the pressing member 30 and the stopper operating member 40 are offset in the vehicle width direction as shown in FIG. 30 and the stopper operating member 40 do not interfere with each other. Therefore, even if the sliding door 20 is slid in the opening direction, as shown in FIG. 4, the stopper operating member 40 is positioned at the non-operating position and the stopper 60 is positioned at the non-interfering position. Therefore, even when the lock device 23 and the lock striker 22 are unlocked and the slide door 20 in the fully closed position is slid in the opening direction, the lower arm 16 does not contact the stopper 60 as shown in FIG. Therefore, the slide door 20 can be slid to the fully open position.
On the other hand, when the pressing member 30 moves to the pressing position with the opening degree of the window glass 27 exceeding the predetermined opening degree as in the fully open position, as shown by a two-dot chain line in FIG. The end portion and the position in the vehicle width direction and the vertical position of the stopper operating member 40 coincide (overlap in the front-rear direction). Therefore, when the slide door 20 located at the fully closed position slides rearward and the pressing member 30 reaches the same position as the stopper operating member 40, the vertical piece 29 of the pressing member 30 moves to the stopper operating member 40 as shown in FIG. Contacting the upper surface of the pressed portion 43, the stopper operating member 40 is rotated downward against the biasing force of the torsion coil spring. When the lower surface of the vertical piece 29 of the pressing member 30 contacts the pressed flat surface 44 of the pressed portion 43, the stopper operating member 40 reaches the operating position. When the stopper operating member 40 is moved to the operating position in this way, the engaging pin 62 engaged with the rear end portion of the long hole 45 as shown in FIG. 4 is moved to the front end portion of the long hole 45 as shown in FIG. The stopper 60 moves from the non-interference position to the interference position. When the stopper 60 reaches the interference position in this way, the pressed surface 61 of the stopper 60 that has been located below the lower arm 16 (positioned so as not to interfere with the lower arm 16) is the same height as the lower arm 16. Therefore, the rear surface of the lower arm 16 comes into contact with the pressed surface 61 of the stopper 60, and further rearward sliding of the slide door 20 is restricted.

(Operation when opening the fuel lid 76)
When a fuel lid release switch (not shown) provided in the vehicle is pressed, the fuel lid 76 located at the closed position rotates to the open position and opens the fuel lid opening 75. Then, since the rotation operation of the fuel lid 76 is transmitted to the fuel lid interlocking lever 50 via the linkage rod 70, the fuel lid interlocking lever 50 positioned at the non-operating position as shown in FIG. 6 rotates and moves to the operating position. Then, the pressing portion 53 of the fuel lid interlocking lever 50 presses the engaging pin 62 downward, so that the stopper 60 located at the non-interference position rotates forward, and the fuel lid interlocking lever 50 reaches the operating position. The stopper 60 reaches the interference position.
Accordingly, when the slide door 20 that has been in the fully closed position in this state is slid rearward, the lower arm 16 abuts against the pressed surface 61 of the stopper 60, so that further rearward sliding of the slide door 20 is restricted. Is done. This prevents the rear end surface of the slide door 20 from coming into contact with the fuel lid 76 located at the open position.

As described above, the intermediate stopper mechanism of the present embodiment has the lower arm 16, which is a member having higher mechanical strength than the pressing member 30 and both ends of which are supported by the lower rail 14 and the slide door 20, as the stopper 60. In this structure, sliding in the opening direction of the sliding door 20 is stopped. Therefore, the sliding door 20 can be reliably stopped at a predetermined position when the window glass 27 is opened beyond a predetermined opening degree.
Further, the pressing member 30 according to the present embodiment is not a member for stopping the sliding of the sliding door 20 by contacting the stopper as in the prior art, but is a member for rotating the stopper operating member 40, so that the pressing member 30 is required. The mechanical strength is considerably smaller than that of the lower arm 16. Therefore, there is no need to increase the thickness of the pressing member 30 or to mold it with an expensive material. Further, since the rotation support shaft 31 that is a pivoting means of the pressing member 30 and the lower arm 16 is not required to have a large mechanical strength, the components of the pivoting mechanism of the pressing member 30 and the lower arm 16 can be formed of a large member. There is no need to mold with expensive materials. Therefore, the total weight of the slide door 20, the lower arm 16, the pressing member 30, and the rotation support shaft 31 does not increase. Furthermore, the manufacturing cost of the pressing member 30 and the rotation support shaft 31 can be kept low.

  Further, the bottom portion of the door opening 12 (such as the bottom plate 37 and the side walls of the storage space 39) is a portion that increases the rigidity of the vehicle body 10, and is designed to increase the mechanical strength. Since the stopper operating member 40, the fuel lid interlocking lever 50, and the stopper 60 are provided in such a high mechanical strength location, the space between these members and the vehicle body 10 is compared to the case where the mechanical strength is provided elsewhere. Support strength is improved. Therefore, the sliding door 20 can be stopped more reliably as compared with the case where the stopper operating member 40, the fuel lid interlocking lever 50, and the stopper 60 are provided in other places.

  Further, a stopper mechanism (lower arm 16, fuel lid interlocking lever 50, stopper 60, and linkage rod 70) for preventing collision of the fuel lid is configured using components of the intermediate stopper mechanism (lower arm 16, stopper 60). Therefore, the fuel lid collision prevention stopper mechanism can be made inexpensive and simple as compared with a case where the stopper mechanism is completely separate from the intermediate stopper mechanism.

The present invention is not limited to the above-described embodiment, and can be implemented with various modifications.
For example, in this embodiment, the pressing member 30, the stopper operating member 40, the fuel lid interlocking lever 50, and the stopper 60 are disposed at the bottom of the door opening 12, but these are disposed at the ceiling of the door opening 12, and the stopper The sliding of the sliding door 20 in the opening direction may be regulated by bringing the upper arm 15 into contact with 60. It can also be provided in the vicinity of a center rail (not shown) provided on the side surface of the vehicle body 10.
Further, the stopper 60 of the intermediate stopper mechanism may be linked to a device (body side switching means) other than the fuel lid 76. For example, the stopper 60 may be moved to the interference position in conjunction with the operation of a child protection switch provided in the driver's seat or the like. Further, in a vehicle having a structure in which seats are provided in three rows in the front-rear direction in the vehicle and the slide door 20 is opened to the side in the third row when the slide door 20 is slid to the fully open position, the seat is provided in a driver seat or the like. When the slide range restriction switch is operated, the stopper 60 rotates to the interference position, and the lower arm 16 abuts against the stopper 60, so that the slide door 20 is stopped in the open state to the second row. .
Further, the pressing member 30 may be provided not on the lower arm 16 but on the slide door 20.
Alternatively, the stopper actuating member 40 may be provided with an engaging pin 62 protruding, and the stopper 60 may be provided with a long hole 45.
