  Next, the operation of the sliding door structure 10 having the above configuration will be described.

  In the configuration of the present embodiment, when the slide door 12 is slid to the vehicle rear side, the door drive motor device 30 is driven in the door closing direction, or the slide door 12 is manually slid to the vehicle front side. The slide door 12 slides toward the vehicle front side and closes the door opening 13. At this time, the slide door 12 receives a reaction force accompanying deformation of the weather strip 20 disposed between the slide door 12 and the rocker portion 14 (see FIG. 3).

  Here, in the sliding door structure 10 according to the present embodiment, as described above, the hinge reinforcement 38 is provided on the sliding door 12 and the reinforcing portion 32 is formed on the door hinge 24, so that the door hinge mounting portion in the sliding door 12 is formed. A portion between 34 and the seal reaction force receiving portion 36 is reinforced. According to this configuration, even if a reaction force is applied to the slide door 12 from the weather strip 20 when the slide door 12 closes the door opening 13, the reaction force is received by the hinge reinforcement 38 and the reinforcing portion 32 of the door hinge 24. It is done. Therefore, the deformation of the portion between the door hinge mounting portion 34 and the seal reaction force receiving portion 36 with the door hinge mounting portion 34 as a fulcrum is suppressed, and the sliding door 12 falls to the outside of the vehicle due to the reaction force of the weather strip 20. It is suppressed. Thereby, the door closing property at the time of manual operation and electric operation becomes good.

  In particular, even when the link arm 18 is swung by the door drive motor device 30 and the slide door 12 is electrically closed, as described above, the sliding door 12 is deformed to fall outside the vehicle due to the reaction force of the weather strip 20. By suppressing the load, the load in the door closing direction applied to the door hinge 24 via the link arm 18 is sufficiently transmitted to the door lock devices 48 and 50, and the door closing performance is improved.

  Moreover, in order to clarify the effect of the sliding door structure 10 according to the present embodiment, the following description will be made in more detail using comparative examples of FIGS. 14 and 15. In the sliding door structure 110 of the comparative example shown in FIGS. 14 and 15, the hinge reinforcement 38 is provided, but the reinforcing portion 32 is not provided in the door hinge 24 as in the present embodiment, and A closed section 59 is not formed. For this reason, when the sliding door 12 receives a reaction force from the weather strip 20, the hinge reinforcement 38 cannot sufficiently receive the reaction force, and is indicated by an imaginary line (two-dot chain line) in FIG. As described above, the sliding door 12 is deformed by falling to the outside of the vehicle due to the reaction force of the weather strip 20.

  On the other hand, in the sliding door structure 10 according to the present embodiment, as shown in FIG. 3, the reinforcing portion 32 and the hinge reinforcement 38 are provided so as to straddle the seal reaction force receiving portion 36. Further, a closed cross section 59 is formed by the main body portion 26 of the door hinge 24, the reinforcing portion 32, and the hinge reinforcement 38, and the closed cross section 59 is set at a portion where a reaction force acts from the weather strip 20. (That is, the closed cross section 59 and the weather strip 20 wrap in a side view of the vehicle). Therefore, even if a reaction force acts on the slide door 12 from the weather strip 20 when the slide door 12 closes the door opening 13, this reaction force can be received by the reinforcing portion 32 and the hinge reinforcement 38. Thereby, the fall deformation to the vehicle outer side of the slide door 12 by the reaction force of the weather strip 20 can be suppressed.

  Further, in the sliding door structure 110 of the comparative example shown in FIG. 14 and FIG. 15, the hinge reinforcement 38 is formed between the inner panel 22 and the door hinge 24 by the fixing tool 40 below the seal reaction force receiving portion 36 in the vehicle vertical direction. The main body 26 and the retainer 42 are integrally fixed. However, the hinge reinforcement 38 is not coupled to the inner panel 22 on the upper side in the vehicle vertical direction with respect to the seal reaction force receiving portion 36 and is not joined to the front lock reinforcement 46 on the upper end side thereof. For this reason, the load in the door closing direction (door pulling force) applied to the door hinge 24 via the link arm 18 during the electric drive cannot be sufficiently transmitted to the door lock device 48 and the half lock cannot be reached, or A door closing failure occurs (when the power is closed, the auto-closer does not operate because the half-lock is not reached).

  On the other hand, in the sliding door structure 10 according to the present embodiment, as shown in FIG. 3, the hinge reinforcement 38 is positioned on the upper side in the vehicle vertical direction with respect to the seal reaction force receiving portion 36 by the fastener 44. And coupled to the reinforcing portion 32. Further, as shown in FIG. 4, the upper end of the hinge reinforcement 38 is joined to the front lock reinforcement 46, and the portion between the hinge reinforcement 38 and the door lock device 48 by the front lock reinforcement 46. Is reinforced.

  Therefore, the front lock reinforcement 46 suppresses the deformation of the portion between the door hinge mounting portion 34 and the door lock device 48 with the door hinge mounting portion 34 as a fulcrum, and suppresses the deformation of the sliding door 12 falling to the outside of the vehicle. The As a result, a load in the door closing direction (door pulling force) applied to the door hinge 24 via the link arm 18 during electric operation is sufficiently transmitted to the door lock device 48, and the door closing performance is improved. That is, since the door lock device 48 reliably reaches the half-lock position, an auto closer (not shown) can be operated, and the occurrence of a door closing failure can be prevented.

  Furthermore, in the sliding door structure 10 according to the present embodiment, the portions between the door lock devices 48 and 50 provided on both ends of the sliding door 12 in the door width direction are the beltline reinforcement inner 54 and the beltline reinforcement outer 56. It is reinforced by the impact beam 58. Therefore, deformation of the portion between the door lock devices 48 and 50 in the slide door 12 is suppressed by the beltline reinforcement inner 54, the beltline reinforcement outer 56 and the impact beam 58. Thus, the load transmitted to the front door lock device 48 is sufficiently applied to the rear door lock device 50 via the belt line reinforcement inner 54, the belt line reinforcement outer 56, the impact beam 58, and the rear lock reinforcement 52. Since it is transmitted, the door closing property becomes better.

  Thus, even when the link arm 18 is swung by the door drive motor device 30 as in the slide door structure 10 according to the present embodiment, according to each of the above configurations of the present embodiment, the door drive is performed. Since the driving force of the link arm 18 by the motor device 30 can be sufficiently transmitted to the door lock devices 48 and 50, the door closing property is improved, and the sliding door 12 can be reliably closed by electric (automatic driving). Become.

  Next, a modification of this embodiment will be described.

  In the above embodiment, the hinge reinforcement 38 and the front lock reinforcement 46 are joined to reinforce the portion between the hinge reinforcement 38 and the door lock device 48. For example, the hinge reinforcement 38 and the door When the rigidity of the portion between the lock device 48 is ensured, the hinge reinforcement 38 and the front lock reinforcement 46 may not be joined.

  In the above embodiment, the front lock reinforcement 46 and the rear lock reinforcement 52 are connected by the beltline reinforcement inner 54, the beltline reinforcement outer 56, and the impact beam 58, so that the door lock devices 48, 50 are connected. For example, when the rigidity of the portion between the door lock devices 48 and 50 is ensured, the beltline reinforcement inner 54, the beltline reinforcement outer 56, and the impact beam 58 are provided. Therefore, the front lock reinforcement 46 and the rear lock reinforcement 52 may not be connected.

  Moreover, in the said embodiment, although the slide door structure 10 was applied to the rear door, you may apply to a front door or a back door.

  Moreover, in the said embodiment, although the link arm 18 was provided in the rocker part 14 below the slide door 12, the link arm 18 may be provided in a roof side part, and the rocker part 14 and roof side It may be provided in both of the parts.

According to this configuration, even if a reaction force is applied to the slide door 12 from the weather strip 20 when the slide door 12 closes the door opening 13, the reaction force is applied by the door inner reinforcement 74 and the shaft portion 72 of the hinge pin 64. It is accepted. Therefore, the deformation of the portion between the door hinge mounting portion 34 and the seal reaction force receiving portion 36 with the door hinge mounting portion 34 as a fulcrum is suppressed, and the sliding door 12 falls to the outside of the vehicle due to the reaction force of the weather strip 20. It is suppressed. Thereby, the door closing property at the time of manual operation and electric operation becomes good.

  In particular, even when the link arm 18 is swung by the door drive motor device 30 (see FIG. 2) and the slide door 12 is electrically closed as in the present embodiment, the anti-weathering of the weather strip 20 is performed as described above. By restraining the sliding door 12 from falling down to the outside of the vehicle due to force, the load in the door closing direction applied to the door hinge 62 via the link arm 18 is sufficiently transmitted to the door lock devices 48 and 50 (see FIG. 1). As a result, the door closing property is improved.

  In the slide door structure 60 according to the present embodiment, the door inner reinforcement 74 and the shaft portion 72 are integrally fixed. As shown in FIG. 10, a closed cross section 99 is formed by the door inner reinforcement 74 and the shaft portion 72, and the closed cross section 99 is set at a portion where a reaction force acts from the weather strip 20. (That is, the closed section 99 and the weather strip 20 wrap in a side view of the vehicle).

  Therefore, even when the sliding door 12 receives a reaction force from the weather strip 20, the reaction force can be received by the closed section 99, so that a load in the door closing direction (door pulling force) applied to the door hinge 62 is locked by the door lock. Fully communicated to device 48. As a result, the door lock device 48 reliably reaches the half-lock position, so that an auto closer (not shown) can be operated, and the occurrence of a door closing failure can be prevented.

  Further, in the slide door structure 60 according to the present embodiment, the shaft reaction portion 72 protruding from the door hinge 62 to the upper side of the vehicle is sealed by the upper fixed support wall portion 82 of the door inner reinforcement 74 fixed to the slide door 12. It is supported above the portion 36. According to this configuration, the slide door 12 can be held in a wide vertical range (vertical pitch), and the holding rigidity of the slide door 12 is improved against the reaction force of the weather strip 20. Even if the temporary placement position of the slide door 12 on the door hinge 62 is separated from the position of the center of gravity of the door, the shaft portion 72 is supported by the door inner reinforcement 74 so that the slide door 12 can be temporarily placed on the door hinge 62 as described above. This makes it possible to place the slide door 12 on the vehicle body.

  In general, when the opening degree of the slide door 12 is to be increased, the attachment position of the door hinge 62 on the slide door 12 side is often set in front of the vehicle rather than the center of gravity of the entire door. When the center of gravity of the entire door is set behind the door hinge 62 in this way, the temporary placement balance of the sliding door 12 is poor when the sliding door 12 is temporarily placed on the door hinge 62, and the sliding door 12 is moved backward. There is a possibility of tilting.

  However, in the sliding door structure 60 according to the present embodiment, the shaft portion 72 on the door hinge 62 side is extended in the vertical direction to ensure the vertical pitch, and the shaft portion 72 is spaced apart in the vehicle front-rear direction to ensure the front-rear pitch. Therefore, the holding rigidity of the slide door 12 when the shaft portion 72 is supported by the door inner reinforcement 74 is sufficiently ensured. Therefore, when the slide door 12 is temporarily placed on the door hinge 62, the temporary placement balance of the slide door 12 can be improved, and the backward tilt of the slide door 12 can be prevented. Furthermore, as described above, the shaft portion 72 on the door hinge 62 side is extended in the vertical direction to ensure the vertical pitch, so that the vertical dimension of the door clamping surface can be secured, and the inclination of the slide door 12 in the vehicle width direction is also possible. Can be prevented.

  Further, in the slide door structure 60 according to the present embodiment, as described above, the position of the slide door 12 in the vehicle vertical direction is adjusted with respect to the door hinge 62 (door inclination adjustment, overall door height adjustment) in the vehicle side view. Therefore, the installation adjustment of the slide door 12 can be easily performed.

  Further, in the slide door structure 60 according to the present embodiment, as described above, since the shaft portion 72 is supported by the door inner reinforcement 74, the necessary door even if the mounting surface of the door hinge 62 with the slide door 12 is small. Holding rigidity can be ensured.

  Although not particularly shown in the present embodiment, the front lock reinforcement 46 (reinforcement of door lock reinforcement) that reinforces the portion between the door inner reinforcement 74 and the door lock device 48, as in the first embodiment. Means) (see FIG. 1 above), even if the door hinge 62 is mounted at a position spaced vertically from the door lock device 48, the door hinge mounting portion 34 is mounted on the door hinge mounting portion 34 by the front lock reinforcement 46. The deformation of the portion between the portion 34 and the door lock device 48 is suppressed, and the sliding deformation of the sliding door 12 to the outside of the vehicle is suppressed. As a result, the load in the door closing direction applied to the door hinge 62 when electrically operated is sufficiently transmitted to the door lock device 48, and the door closing performance is improved.

  Similarly to the first embodiment, the portions between the door lock devices 48 and 50 provided at both ends of the slide door 12 in the door width direction are the beltline reinforcement inner 54, the beltline reinforcement outer 56, the impact. When reinforced by the beam 58 (reinforcement means between door locks) (see FIG. 1 above), the deformation of the portion between the door lock devices 48 and 50 in the slide door 12 is changed to the beltline reinforcement inner 54 and the beltline reinforcement. It is suppressed by the outer 56 and the impact beam 58.

  As a result, the load in the door closing direction applied to the door hinge 62 via the link arm 18 when electrically operated is sufficiently transmitted to the front door lock device 48 via the front lock reinforcement 46 and transmitted to the front door lock device 48. The applied load is transmitted to the rear door lock device 50 via the beltline reinforcement inner 54, the beltline reinforcement outer 56, the impact beam 58, and the rear lock reinforcement 52. Thereby, a door closing property becomes more favorable.

  As described above, even when the link arm 18 is swung by the door drive motor device 30 as in the slide door structure 60 according to the present embodiment, the door drive according to each configuration of the present embodiment. Since the driving force of the link arm 18 by the motor device 30 can be sufficiently transmitted to the door lock devices 48 and 50, the door closing property is improved, and the sliding door 12 can be reliably closed by electric (automatic driving). Become.

  Next, a modification of this embodiment will be described.

  In the above embodiment, the shaft portion 72 is integrally formed with the hinge pin 64. However, as shown in FIG. 12, for example, the shaft portion 72 is separate from the hinge pin 64 and is integrally formed with the door hinge 62 by welding or the like. It may be fixed. Further, in this case, as shown in the drawing, the shaft portion 72 is disposed on the outer side in the vehicle front-rear direction with respect to the hinge pin 64, and the front-rear pitch of the shaft portion 72 is set to the mounting portion (the pair of link arms 18 of the pair of link arms 18). If it is made wider along the door width direction than the mounting pitch), the space between the shaft portions 72 can be made wider than the space between the hinge pins 64 (the space between the link arms 18), so that the sliding door 12 is more stable with respect to the door hinge 62. Door holding rigidity can be obtained.

  Further, the front and rear pitch of the shaft portion 72 is made wider along the door width direction than the attachment portion of the link arm 18 to the door hinge 62 (attachment pitch of the pair of link arms 18). The reaction force can be received in a wider range in the door width direction. Therefore, the sliding deformation of the slide door 12 to the outside of the vehicle due to the reaction force of the weather strip 20 is further suppressed. Further, since the tilt movement in the door width direction (vehicle front-rear direction) at the door hinge mounting portion 34 of the slide door 12 is further suppressed, the door lock devices 48 and 50 of the slide door 12 are lowered due to the door being lowered (incorrect installation). It becomes possible to reliably suppress the lock failure.

  Moreover, in the said embodiment, although the axial part 72 was directly inserted in the upper through-hole 86 formed in the upper side fixed support wall part 82 of the door inner reinforcement 74, as FIG. 13 shows, for example The shaft portion 72 may be inserted into the upper through hole 86 via, for example, a resin grommet 100. Further, in this case, if the hole 102 of the grommet 100 is formed in a tapered shape having a diameter that decreases toward the distal end side in the insertion direction of the shaft 72, the shaft 72 is inserted into the hole 102 of the grommet 100. At this time, centering is facilitated, and assembly workability is improved. Further, by providing the grommet 100, it is possible to prevent direct contact between the shaft portion 72 and the door inner reinforcement 74, thereby suppressing occurrence of abnormal noise when the door is closed or when the vehicle is traveling.

  In addition, it is needless to say that the configuration of the second embodiment of the present invention can be modified similarly to the first embodiment.
