JP, 2017-128272, A

  Although the starting force of the sliding door is assisted by the restoring force of the torsion spring of the hinge, in the technique of Patent Document 1, this assisting force is fixed and it is possible to adjust it according to the preference of the user. Can not.

  Therefore, a main object of the present invention is to provide a slide door hinge mechanism capable of adjusting the operation force required to open and close the slide door according to the user's preference.

  The slide door hinge mechanism according to the present invention includes a door side hinge attached to the slide door, a rail side hinge attached to the slide rail of the vehicle body, a hinge pin pivotally supporting the door side hinge and the rail side hinge, and an axis extending parallel to the hinge pin. A restricting member provided rotatably on one of the door side hinge and the rail side hinge, one end engaging with the restricting member, and the other end engaging with the other of the door side hinge and the rail side hinge A torsion spring is wound around the hinge pin, and an adjustment member that variably adjusts the rotation angle of the restriction member.

  The second operation force required to open and close the slide door decreases as the amount of torsion of the torsion spring increases. Based on this, in the present invention, the rotation angle of the regulating member engaged with one end of the torsion spring is variably adjusted. As a result, the operating force required to open and close the slide door can be adjusted to the user's preference.

  Referring to FIGS. 1 (A), 1 (B), 2 (A) and 2 (B), the slide door hinge mechanism 10 of this embodiment includes a door side hinge 12 attached to a slide door (not shown) and And a rail side hinge 14 attached to a slide rail of a vehicle body (not shown). The angle between the door side hinge 12 and the rail side hinge 14 changes appropriately when the slide door is opened and closed.

  In this embodiment, for convenience of explanation, the X axis is assigned in the longitudinal direction of the vehicle, the Y axis is assigned in the width direction of the vehicle, and the Z axis is assigned in the height direction of the vehicle. In particular, in the Y-axis direction, the direction away from the vehicle body is the positive side.

  Based on this, the inner side surface of the door side hinge 12 faces the negative side in the Y axis direction, and the outer side surface of the door side hinge 12 faces the positive side in the Y axis direction. On the other hand, the inner side surface of the rail side hinge 14 faces the positive side in the X axis direction, and the outer side surface of the rail side hinge 14 faces the negative side in the X axis direction.

  The door side hinge 12 and the rail side hinge 14 are pivotally supported by a hinge pin 16 extending in the Z-axis direction, and are rotatable around the axis of the hinge pin 16. Further, a regulating member 20 is provided on the inner side surface of the rail side hinge 14. The regulating member 20 comprises a plate 20pl and a shaft 20sh (see FIG. 4), and is pivotally supported by a hinge pin 22 extending in the Z-axis direction in the vicinity of the hinge pin 16. Therefore, the plate 20pl is rotatable around the axis of the hinge pin 22.

  A torsion spring 18 is wound around the hinge pin 16. One end of the torsion spring 18 engages with the regulating member 20, and the other end of the torsion spring 18 engages with the door side hinge 12. Specifically, one end of the torsion spring 18 moves on one main surface of the plate 20pl along a groove GR1 provided in the plate 20pl. On the other hand, the other end of the torsion spring 18 reaches from the inner side surface of the door side hinge 12 to the outer side surface through the notch C1 provided in the door side hinge 12.

  When the one end and the other end of the torsion spring 18 respectively engage with the regulating member 20 and the door side hinge 12, the torsion amount of the torsion spring 18 is the plate 20 pt that constitutes the inner side surface of the door side hinge 12 and the regulating member 20. Depends on the angle between the main surface of the That is, the amount of torsion of the torsion spring 18 decreases as the angle increases (see FIG. 3A), and the amount of torsion of the torsion spring 18 increases as the angle decreases (see FIG. 3B).

  As can be seen from FIG. 1B, the rail side hinge 14 is formed with circular through holes H1 and H2 that reach from the inner surface to the outer surface. The position of the through hole H2 is aligned with the position of the through hole H1 in the Y-axis direction, and is lower than the position of the through hole H1 in the Z-axis direction.

  Referring to FIG. 4, substantially keyhole-shaped through holes H3 and H4 are additionally formed in the plate 20pl forming the restricting member 20. As shown in FIG. The through holes H3 and H4 are formed laterally long at positions aligned in the height direction, and the round hole of the through hole H3 and the round hole of the through hole H4 are both disposed on the shaft 20sh side.

  When the regulating member 20 is attached to the rail side hinge 14, the height position of the through hole H3 is aligned with the through hole H1, and the height position of the through hole H4 is aligned with the through hole H2. The outer diameter of the round hole of the through hole H3 is slightly larger than the outer diameter of the stopper 24st described later, and the outer diameter of the circular hole of the through hole H4 is slightly larger than the outer diameter of the stopper 26st described later.

  Referring to FIGS. 2 (A) and 2 (B), nuts 28 and 30 screwed with stopper bolts 24 and 26, respectively, are provided on the outer surface of the rail side hinge 14. Here, the nuts 28 and 30 are integrally formed with the rail side hinge 14. Further, the inner diameter of the nut 28 substantially coincides with the inner diameter of the through hole H1, and the central axis of the nut 28 overlaps the central axis of the through hole H1. Similarly, the inner diameter of the nut 30 substantially coincides with the inner diameter of the through hole H2, and the central axis of the nut 28 also overlaps the central axis of the through hole H2.

  Referring to FIG. 5, the stoppered bolt 24 is formed by integrally molding a ring-shaped stopper 24st on a hexagonal bolt consisting of a head 24hd and a shaft 24sh. The stopper 24 st is provided at a position slightly closer to the head 24 hd than the longitudinal center of the shaft portion 24 sh.

  The lower surface of the stopper 24st is flat, while the upper surface of the stopper 24st curves and bulges from the outer edge toward the shaft 24sh. Although not shown, a groove for screwing with the nut 28 is cut in the shaft portion 24sh.

  6 (A) and 6 (B), the stoppered bolt 26 is formed integrally with the ring-shaped stopper 26st on the hexagonal bolt consisting of the head 26 hd and the shaft 26 sh like the stoppered bolt 24. It will be done. The stopper 26 st is also provided at a position slightly closer to the head portion 26 hd than the center in the longitudinal direction of the shaft portion 26 sh.

  The lower surface of the stopper 26st is flat, and the upper surface of the stopper 26st curves and bulges from the outer edge toward the shaft 26sh. Further, a groove for screwing with the nut 30 is cut in the shaft portion 26sh.

  However, unlike the stopper 24st, the stoppers 26st have ridges 26wd1 and 26wd2 formed on the upper surface separated by 180 ° from each other. Both 楔 26wd1 and 26wd2 gently rise along the right rotation direction of the head 26 hd.

  1 (A), 1 (B), 2 (A) and 2 (B), the bolt 24 with a stopper passes through the through hole H3 of the plate 20pl and the through hole H1 of the rail side hinge 14 It is screwed into the nut 28. Similarly, the stopper bolt 26 is also screwed into the nut 30 through the through hole H4 of the plate 20pl and the through hole H2 of the rail side hinge 14.

  At this time, the plate 20pl is sandwiched by the head 24hd and the stopper 24st provided on the stopper bolt 24, and is further held by the head 26hd and stopper 26st provided on the stopper bolt 26. A pressing force directed to the right rotation direction is biased from the torsion spring 18 to the regulating member 20 as viewed from the positive side in the Z-axis direction. Therefore, the plate 20pl is continuously pressed against the stoppers 24st and 26st.

  In this state, when the head 24hd of the stopper bolt 24 and the head 26hd of the stopper bolt 26 are rotated to the left, the plate 20pl is rotated toward the door side hinge 12, whereby the torsion of the torsion spring 18 is strengthened. .

  The relative positions of the stoppers 24st and 26st and the through holes H3 and H4 provided in the plate 20pl change as shown in FIGS. 7 and 8 as the plate 20pl rotates. That is, if the rotation angle of the plate 20pl is 0 ° as shown in the upper portion of FIG. 7, the stopper 24st is disposed substantially at the center of the through hole H3 and the stopper 26st is of the through hole H4 as shown in the lower portion of FIG. It is placed approximately in the center.

  On the other hand, as shown in the upper stage of FIG. 8, when the rotation angle of the plate 20pl exceeds 0 °, as shown in the lower stage of FIG. 8, the stopper 24st moves away from the round hole of the through hole H3 and the stopper 26st passes through. Move away from the round hole of hole H4. Therefore, even if the regulating member 20 is rotated, the stoppered bolts 24 and 26 will not come out of the round hole.

  The need for the wedges 26wd1 and 26wd2 formed on the upper surface of the stopper 26st is as follows.

  That is, since the left rotation direction of the heads 24 hd and 26 hd is a direction in which the amount of torsion of the torsion spring 18 increases, the heads 24 hd and 26 hd do not easily rotate left. On the other hand, since the right rotation direction of the heads 24 hd and 26 hd is a direction in which the amount of torsion of the torsion spring 18 is weakened, the heads 24 hd and 26 hd easily rotate right by vibration or the like.

  Therefore, in this embodiment, the ridges 26wd1 and 26wd2 are formed on the upper surface of the stopper 26st. Since the rear parts of the ridges 26wd1 and 26wd2 hit the inner peripheral surface of the through hole H4 when the head 24hd rotates right, this limits the right rotation of the head 24hd.

  When it is desired to intentionally turn the head 26 hd to the right in order to reduce the amount of torsion of the torsion spring 18, the plate 20 pl may be separated from the stopper 26 st. This can be achieved by rotating the head 24 hd of the stopper bolt 24 to the left.

  As can be understood from the above description, the door side hinge 12 attached to the slide door and the rail side hinge 14 attached to the slide rail of the vehicle body are pivotally supported by the hinge pins 16. The restricting member 20 is provided on the rail side hinge 14 so as to be rotatable around an axis extending parallel to the hinge pin 16. The torsion spring 18 is wound around the hinge pin 16 with one end engaging with the regulating member 20 and the other end engaging with the door side hinge 12. The rotation angle of the regulating member 20 is variably adjusted by the stopper bolts 24 and 26.

  The start operation force of the slide door decreases as the amount of torsion of the torsion spring 18 increases. Based on this, in this embodiment, the rotation angle of the regulating member 20 engaged with one end of the torsion spring 18 is variably adjusted. As a result, the operating force required to open and close the slide door can be adjusted to the user's preference.

  In this embodiment, the rail hinge 14 is provided with the restricting member 20. Alternatively, the door hinge 12 may be provided with the restricting member 20 instead.
