Description

  The present invention relates to a slide door device used for a vehicle, for example.

  An opening for an occupant to get on and off is formed in the body of the automobile. The opening is covered by a door device so as to be opened and closed.

  For example, in a wagon type automobile, the opening formed in the rear seat is relatively large. For this reason, in order to suppress interference between the door body in the opened state and the outside of the vehicle body (if the door body is large, the opened door body and the obstacle outside the vehicle easily come into contact), A slide door device has been proposed as a door device for opening and closing the opening. The sliding door device opens and closes the opening by sliding the door body along the outer surface of the vehicle body.

  This type of sliding door device includes a door body that opens and closes a vehicle body opening, and a slide link mechanism that connects the vehicle body and the door body and slides the door body relative to the vehicle body.

  Specifically, the slide link mechanism includes a fixed side base fixed to the vehicle body side and a movable side base fixed to the door body side. The fixed side base and the movable side base include the slide link mechanism. Are connected to each other.

  The slide link mechanism includes a parallel link. By this parallel link, the posture of the door body is displaced substantially outward in the vehicle body width direction from a closed state (a state where the opening is closed) to a slidable position.

The door body displaced to the slidable position slides along the outer surface of the vehicle body by the slide link mechanism, and thus moves away from the opening. As a result, the opening is opened (see, for example, Patent Document 1).
JP 2007-253895 A

  However, in the sliding door device disclosed in Patent Document 1, when the door body is opened from the closed state, that is, before sliding in the opening direction along the outer surface of the vehicle body, the position of the door body is temporarily set in the vehicle width direction. Displace. Next, it slides in the opening direction along the outer surface of the vehicle body. Similarly, when the door body is closed from the open state, the door body is slid to the opening along the outer surface of the vehicle body and then pushed into the vehicle interior along the substantially vehicle width direction.

  Thus, the sliding door device disclosed in Patent Document 1 requires an operation of moving the door body in the vehicle width direction and an operation of sliding the door body in the longitudinal direction of the vehicle body in order to open and close the door body. Since each moving direction is different, the opening / closing operation is complicated.

  When the occupant moves the door body, the occupant grips the door knob. The shape of the door knob needs to be formed so as to facilitate the movement of the door body. However, if there are two directions of movement of the door body, the width direction of the vehicle and the longitudinal direction of the vehicle body as described above, the shape of the door knob is considered so that it can easily move along the two directions. It becomes complicated and it becomes difficult to perform the operation of the occupant itself.

  On the other hand, in the sliding door device, a sensor is provided at the front end of the door body in order to prevent, for example, an occupant from being caught between the edge of the opening and the door body.

  However, as described above, the door body moves in the vehicle width direction at a position in the vicinity of the opening (position immediately before covering the opening).

  For this reason, the sensor has a function of detecting the front-rear direction of the vehicle body when the door body slides in the front-rear direction of the vehicle body to a position in the vicinity of the opening, and the vehicle width direction when moving from the vicinity of the opening to the inner side of the vehicle width direction It is necessary to have a function of performing detection in two directions with a function of detecting. Thus, a sensor having a multidirectional detection function is expensive.

  In addition, when a large load is input from the front of the vehicle body, for example, when a car collides, the door body that covers the passenger's entrance opening of the front seat (for example, the passenger seat or the driver's seat) Displace backwards.

  The front seat opening and the rear seat opening are adjacent to each other. Therefore, when the door body covering the opening for the front seat is displaced rearward by the load, the rear edge of the door body (the edge facing the door body of the sliding door device) is located inside the door body of the sliding door device. Come in.

  For this reason, the door bite for preventing the door body covering the front seat opening from entering the front edge of the door body of the slide door device (the edge facing the door body covering the front seat opening). A prevention structure is provided. As an example of this type of prevention structure, for example, a rubber member is provided at the edge of the door main body of the slide door device to prevent the door main body from entering the front opening.

  However, as described above, since the slide door body moves in the vehicle width direction at a position near the opening, when the door body moves in the vehicle width direction, the rubber member described above interferes with the edge of the opening. It is possible to end up. As a result, the opening / closing operation of the door body of the sliding door device is hindered.

  Accordingly, an object of the present invention is to provide a sliding door device that can keep the cost low while facilitating the opening and closing operation.

The sliding door device of the present invention includes a door member that can open and close an opening formed in a vehicle body, and the door member between a fully closed position that closes the opening and a fully open position that opens the opening. And a slide link mechanism that can be opened and closed. The slide link mechanism includes a link mechanism that pivotally displaces the door member between the fully closed position and a protruding position displaced inward and outward of the vehicle body with respect to the fully closed position; A slide mechanism that slides along the vehicle body between a position and the fully open position. The link mechanism includes a first link member rotatably connected to the vehicle body side and the door member side, and an opening direction front side of the sliding direction of the door member with respect to the first link member. And a second link member that is disposed and rotatably connected to the vehicle body side and the door member side. The first length between the first axis of the rotating shaft on the vehicle body side in the first link member and the second axis of the rotating shaft on the door member side is the second length. The link member is set to be smaller than the second length between the third axis of the rotating shaft on the vehicle body side and the fourth axis of the rotating shaft on the door member side. A third length between the first axis and the third axis that is the rotation axis on the vehicle body side in the first and second link members is greater than the first length. Set small. A fourth length between the second axis and the fourth axis on the door member side of the first and second link members is set to be smaller than the third length.

  In a preferred embodiment of the present invention, the slide mechanism includes a guide portion that guides the sliding of the door member. The guide portion has a curved portion that is convex toward the outside of the vehicle body.

  In the present invention, it is possible to provide a sliding door device that can keep the cost low while facilitating the opening and closing operation.

  The slide door body 21 opens and closes the rear opening 15. FIG. 1 shows a state in which the rear opening 15 is closed by the slide door main body 21. FIG. 2 is a side view showing a state in which the rear opening 15 is fully opened, that is, a state in which the slide door body 21 is slid to the fully opened position. The slide door main body 21 is an example of a door member referred to in the present invention. The rear opening 15 is an example of the opening referred to in the present invention.

  The slide door main body 21 has a rear opening 15 from a fully closed position P1 (shown in FIG. 1) held by the vehicle body 11 in a state where the rear door 15 is closed by the latch mechanism or the like. Is slid along the outer surface 16 of the vehicle body 11 to a fully open position P2 (shown in FIG. 2). Similarly, it slides along the outer surface 16 of the vehicle body 11 from the fully open position P2 to the fully closed position P1.

  The slide link mechanism 30 and the rotation link mechanism 50 connect the slide door main body 21 to the vehicle body 11, and the slide door main body 21 between the fully closed position P <b> 1 and the fully open position P <b> 2 described above. 16 has a function of sliding in the front-back direction.

  The outer surface 16 of the vehicle body 11 referred to here indicates the outer surface of a panel member (outer panel) that constitutes a side wall portion of the vehicle body 11 behind the rear opening 15 of the vehicle body 11.

  FIG. 3 is a perspective view showing a part of the slide door body 21 as seen from the inside in the vehicle width direction (from the passenger compartment side). In the drawing, parts other than the slide door main body 21 (other parts of the vehicle body 11) are omitted. As shown in FIGS. 1 to 3, the slide door body 21 includes an outer panel 22 (shown in FIGS. 1 and 2), an inner panel 23 (shown in FIG. 3), and a cover member 200 (partially shown in FIG. 11). Etc.

  Outer panel 22 defines, for example, an outer portion (vehicle outer portion) of the exterior of slide door body 21. The inner panel 23 defines, for example, an inner portion (vehicle compartment side portion) of the appearance of the slide door main body 21. By combining the outer panel 22 and the inner panel 23, a main portion of the appearance of the slide door body 21 is configured. In FIG. 3, the outer panel 22 is omitted, and the inner panel 23 is shown.

  As shown in FIG. 3, a slide link mechanism 30 and a rotation link mechanism 50 which will be described later are accommodated in the slide door main body 21, and therefore, the inner panel 23 is provided in the slide door main body 21. An opening 24 for accommodating the slide link mechanism 30 and the rotation link mechanism 50 is formed. The cover member 200 described above covers the opening 24.

  FIG. 4 shows a state in which the slide link mechanism 30 and the rotation link mechanism 50 are disassembled from the slide door body 21 (inner panel 23). FIG. 5 shows a state in which the slide link mechanism 30 is disassembled. As shown in FIG. 5, the slide link mechanism 30 includes a vehicle body side portion 31 fixed to the vehicle body 11 and a door side portion 32 fixed to the slide door main body 21.

  The door side portion 32 includes a movable base 33 fixed to the slide door main body 21, a rail member 34, and the like. The movable side base 33 functions as a fixing portion for fixing a rail member 34 described later to the slide door main body 21. As shown in FIG. 3, the movable base 33 has a plate shape, and is fixed to the outer panel 22 of the slide door main body 21, for example.

  The rail member 34 has a function of guiding the slide door body 21 when the slide door body 21 slides substantially along the outer surface 16 of the vehicle body 11. As shown in FIG. 5, the rail member 34 has a C-shaped cross section that opens to one side, and is fixed to the movable side base 33. The rail member 34 faces the movable side base 33 in a posture in which the opening is directed downward (downward of the vehicle body when the slide door body 21 is attached to the vehicle body 11) and the longitudinal direction is along the sliding direction (substantially vehicle body front-rear direction). It is fixed.

  The rail member 34 has a pair of vertical wall portions extending substantially along the vehicle body longitudinal direction F. These vertical wall portions are arranged in the vehicle width direction W in a state where the slide door main body 21 is attached to the vehicle body 11. Among these vertical wall portions, the vertical wall portion arranged on the inner side in the vehicle width functions as a guide portion 35 that guides the slide of the slide door body 21.

  The rail member 34 is curved so as to be convex outward in the vehicle width direction when the slide door body 21 is attached to the vehicle body 11. Therefore, the guide portion 35 is curved so as to protrude toward the outer side in the vehicle width direction. The shape of the rail member 34 will be described later in detail. In addition, being convex toward the vehicle width direction outer side said here is an example of becoming convex toward the vehicle body outer side said by this invention.

  The vehicle body side portion 31 includes a fixed base 36 fixed to the vehicle body 11, a link mechanism 40, and the like.

  As indicated by a dotted line in FIG. 1, the fixed side base 36 is fixed to, for example, a portion located at the rear of the vehicle body in the edge of the rear opening 15. FIG. 6 is a cross-sectional view of the vehicle body 11 taken along line F6-F6 shown in FIG. FIG. 6 shows the rear opening 15 and the sliding door device 20. In FIG. 6, the movable side base 33 and the rotation link mechanism 50 are omitted, and the slide door main body 21 and the vehicle body 11 are indicated by two-dot chain lines (the same applies to FIGS. 8 and 9).

  As shown in FIG. 6, the fixed side base 36 has a fixed wall portion 38. The upper and lower surfaces 38a and 38b of the fixed wall portion 38 are substantially parallel to each other and have a predetermined area along a plane defined by the vehicle width direction W and the vehicle body longitudinal direction F, for example. Note that the upper surface 38a referred to here is a surface facing upward when the slide door body 21 is attached to the vehicle body 11. The lower surface 38 b is a surface facing downward when the slide door body 21 is attached to the vehicle body 11.

  The link mechanism 40 connects the rail member 34 and the fixed base 36, and displaces the slide door main body 21 in the fully closed position P1 to a position separated in the outward direction W1 toward the outside in the vehicle width direction W. It has a function.

  Specifically, the link mechanism 40 has a function of displacing the slide door main body 21 in the fully closed position P1 to a slidable protruding position P3. The protruding position P3 is a position where the slide door body 21 slides from this position toward the rear of the vehicle body. The outer side direction W1 with respect to the vehicle body 11 is an example of the vehicle body inside / outside direction referred to in the present invention.

  FIG. 7 is an exploded perspective view showing the link mechanism 40. As shown in FIG. 7, the link mechanism 40 includes a front link member 41, a rear link member 42, a guide member 43, and a fixed wall portion 38.

  The front link member 41 is rotatably connected to the lower surface 38b of the fixed wall portion 38 via a rotation shaft 44 (shown in FIG. 6). The front link member 41 is freely rotatable along the lower surface of the fixed wall portion 38. The rotating shaft 44 extends, for example, in a substantially vertical direction of the vehicle body (a substantially vertical direction when the vehicle body 11 is placed on a horizontal road surface, where the substantially vertical direction includes the vertical direction). The substantially vehicle body vertical direction is a concept including the vehicle body vertical direction. The front link member 41 is an example of a first link member referred to in the present invention.

  The rear link member 42 is rotatably connected to the fixed wall portion 38 via the rotation shaft 45. The rear link member 42 is freely rotatable in the circumferential direction of the upper surface 38 a of the fixed wall portion 38, and is disposed on the rear side of the front link member 41 in a state where the slide door body 21 is connected to the vehicle body 11. .

  The rear side of the front link member 41 is the front side in the opening direction of the sliding direction of the slide door main body 21. In the present embodiment, the slide door body 21 slides along the substantially front-rear direction F. In the present embodiment, the front side in the opening direction of the sliding direction of the slide door body 21 indicates the rear side of the vehicle body.

  The rotating shafts 44 and 45 are parallel to each other. For this reason, the front / rear side link members 41, 42 can simultaneously rotate around the rotation shafts 44, 45. The rear link member 42 is an example of a second link member referred to in the present invention.

  On the lower surface 43b of the guide member 43, the other end of the front link member 41 (the end opposite to the fixed wall portion 38) and the other end of the rear link member 42 (the end opposite to the fixed wall portion 38). Are connected to each other by rotating shafts 46 and 47. The front link member 41 has, for example, an intermediate portion bent in the vertical direction. Therefore, the upper surface of the other end portion of the front link member 41 and the upper surface of the other end portion of the rear link member 42 are substantially the same. It is a flat surface.

  The rotation shafts 46 and 47 are parallel to the rotation shafts 44 and 45. For this reason, the link mechanism 40 constituted by the fixed wall portion 38, the front / rear side link members 41 and 42, and the guide member 43 can simultaneously rotate around the rotation shafts 44 to 47.

  Roller members 48 and 49 for slidably holding the guide portion 35 of the rail member 34 are provided on the upper surface 43a of the guide member 43. Each roller member 48 and 49 is spaced apart in the vehicle width direction. Each of the roller members 48 and 49 includes rotating shafts 48a and 49a and roller bodies 48b and 49b that rotate around the rotating shafts 48a and 49a. The gap between the roller bodies 48b and 49b is set so that the guide portion 35 of the rail member 34 can be clamped. The roller member that sandwiches the guide portion 35 is not limited to the roller members 48 and 49. Although not shown, a plurality of other roller members may be provided. In this way, the guide part 35 is stably clamped.

  Thus, the slide door body 21 is supported by the link mechanism 40 via the rail member 34 so as to be rotatable around the link mechanism 40. Further, the slide door main body 21 can slide along the outer surface 16 by the guide portion 35 sliding between the roller main bodies 48 b and 49 b. The guide part 35 and the roller members 48 and 49 constitute a slide mechanism 100. The slide mechanism 100 is an example of a slide mechanism referred to in the present invention.

  One end portions of the front and rear link members 41 and 42 are fixed to the fixed wall portion 38. This means that it is fixed to the vehicle body side in the present invention. The term “fixed to the vehicle body” in the present invention does not strictly mean that the vehicle is fixed only to the vehicle body. For example, the vehicle body 11 may be directly fixed, or the vehicle body 11 may be fixed (connected) via the fixed wall portion 38 of the fixed side base 36 as in the present embodiment.

  As described above, the door member (in this embodiment, the sliding door main body 21) is fixed to the vehicle body 11 directly and via other members (in this embodiment, the fixed wall portion 38). Is fixed (connected) to the vehicle body 11 or a portion fixed to the vehicle body 11 so as to be able to perform rotational displacement (rotational displacement between the fully closed position P1 and the protruding position P3). It is.

  The other end portions of the front and rear link members 41 and 42 are fixed to the guide member 43. This means that it is fixed to the door member side in the present invention. In addition, the door member side said by this invention does not show that it fixes to only a door member exactly | strictly. For example, it may be directly fixed to the slide door main body 21 or may be connected (fixed) to the slide door main body 21 via the guide member 43 as in the present embodiment.

  The guide member 43 is connected to the slide door main body 21 via the roller members 48 and 49 and the rail member 34, and therefore, together with the slide door main body 21 when the slide door main body 21 is rotationally displaced with respect to the vehicle body 11. It is rotationally displaced with respect to the vehicle body 11.

  As described above, it includes being connected (fixed) to the slide door main body 21 directly and via another member (in this embodiment, a guide member). More specifically, the door member (in this embodiment, The sliding door body 21) is connected (or fixed) to the door member or the door member so that the sliding door body 21) can be rotationally displaced with respect to the vehicle body (rotational displacement between the fully closed position P1 and the protruding position P3). It is to be fixed (connected) to a portion that is rotationally displaced together with the door member.

  FIG. 8 shows a state where the slide door main body 21 is in the protruding position P3. The sliding door main body 21 is displaced by being rotated by the link mechanism 40 between the fully closed position P1 (shown in FIG. 6) and the protruding position P3 (shown in FIG. 8). As shown in FIG. 9, when the slide door body 21 slides, the posture of the link mechanism 40 is the same as the protruding position P3 (shown in FIG. 8). FIG. 9 shows a state in which the slide door main body 21 is in the fully open position P2 (a state in which the rear side opening 15 is fully opened). 6, 8, and 9, the portion of the rail member 34 that overlaps with the link mechanism 40 is cut out and is indicated by a two-dot chain line for explanation.

  Although not shown, for example, the guide member 43 is provided with a guide pin, and the door side portion 32 (for example, the rail member 34 and the movable side base 33) is provided with a slide guide that contacts the guide pin. It has been.

  When the slide door main body 21 is rotationally displaced by the link mechanism 40 between the fully closed position P1 and the protruding position P3, the slide pin main body 21 slides due to the guide pins and the slide guide coming into contact with each other. To suppress. When the slide door main body 21 is in the projecting position P3, the contact state between the slide pin and the slide guide is released, so that the slide door main body 21 can slide.

  The mechanism for preventing the sliding door body 21 from sliding when the sliding door body 21 is rotationally displaced is not limited to the above.

  Although not shown, the link mechanism 40 includes a stop mechanism that prevents the slide door main body 21 from being rotationally displaced in the opening direction from the protruding position P3. For this reason, when the link mechanism 40 is opened to the protruding position P3, it does not open any more, so that the slide door body 21 starts to slide smoothly.

  Here, the length between the axis lines of the rotating shafts 44 to 47 will be specifically described. FIG. 10 is a plan view schematically showing the link mechanism 40. As shown in FIG. 10, the first length between the shaft centers A1 and A2 of the rotation shafts 44 and 46 is L1. The second length between the axis A3 and A4 of the rotary shafts 45 and 47 is L2. The third length of the axis A1, A3 of the rotation shafts 44, 45 is L3. A fourth length between the axis A2 and A4 of the rotary shafts 46 and 47 is L4. The axial center line A1 is the first axial center line referred to in the present invention. The axis A2 is the second axis according to the present invention. The axis A3 is the third axis according to the present invention. The axis A4 is the fourth axis according to the present invention.

  L2 is larger than L1. L3 is larger than L4. L1 is larger than L3. Therefore, L2> L1> L3> L4.

  As a result, L1 to L4 become unequal lengths, and the imaginary line V1 connecting the axis lines of the rotation shafts 44 and 46 in the front side link member 41 and the axis line of the rotation axes 45 and 47 in the rear side link member 42. It is not always parallel to the virtual line V2 connecting them.

  Further, as shown in FIG. 6, the intersection C between the virtual lines V1 and V2 in a state where the slide door body 21 is in the fully closed position P1, in other words, in a state where the link mechanism 40 is closed is outside the link mechanism 40 (vehicle And the position P4 which is the front side of the link mechanism 40).

  The intersection C when the sliding door main body 21 is in the fully open position P2 or the protruding position P3, in other words, when the link mechanism 40 is open, is outside the link mechanism 40 in the vehicle width direction and more than the position P4. It is located at position P5 on the rear side of the vehicle body. The intersection C is the instantaneous center of rotation of the link mechanism 40. Note that, since L3> L4, the virtual line V1 and the virtual line V2 intersect at the intersection C. In other words, when L3> L4, the instantaneous center of rotation (intersection C) can be formed.

  In other words, the lengths L1 to L4 indicate that the imaginary lines V1 and V2 of the front and rear link members 41 and 42 are not always parallel to each other (during the displacement between the fully closed position P1 and the protruding position P3). In a state where the door main body 21 is in the fully closed position P1, the intersection C is located on the outer side in the vehicle width direction W of the link mechanism 40 and on the front side of the link mechanism 40, and the slide door main body 21 is in the fully open position P2 or protruding. In the state arranged at the position P3, the intersection C is outside the link mechanism 40 in the vehicle width direction W, and the position on the rear side of the vehicle body from the intersection C in the state where the slide door body 21 is in the fully closed position P1. Is set to be placed in

  Further, when the slide door main body 21 is rotationally displaced from the fully closed position P1 to the projecting position P3, the intersection C is always the vehicle of the link mechanism 40 as shown by the dashed line in FIG. It is located outside in the width direction W and is displaced toward the rear of the vehicle body and outside in the vehicle width direction toward the protruding position P3.

  FIG. 11 is a cross-sectional view showing displacement (including rotational displacement and slide displacement by the link mechanism 40) between the fully closed position P1 and the fully open position P2 of the slide door body 21. FIG. In FIG. 11, the slide door main body 21 in the fully closed position P1 and the fully open position P2 is shown by a solid line. Moreover, the front end part 25 and the rear end part 26 of the slide door main body 21 in the state between the fully closed position P1 and the fully open position P2 are shown in the figure.

  FIG. 12 shows an enlarged range F12 indicated by a two-dot chain line in FIG. FIG. 12 shows an enlarged view of the rotational displacement of the front end 25 of the slide door body 21 in the vicinity of the rear opening 15. FIG. 13 shows the displacement of the rear end portion 26 of the slide door main body 21 in the vicinity of the rear opening 15 in an enlarged manner.

  As shown in FIG. 8, when the intersection C (instantaneous rotation center) is set as described above, the slide door main body 21 has a rear end portion 26 that is more than the front end portion 25 than the front end portion 25 in a state where the slide door body 21 is in the protruding position P3. The posture is located outside in the width direction. Further, the posture of the slide door main body 21 at the protruding position P3 is inclined with respect to the posture at the fully closed position P1 so that the rear end portion 26 is located outside.

  For this reason, as shown in FIGS. 11 and 12, the displacement of the slide door body 21 from the fully closed position P1 to the protruding position P3 by the link mechanism 40 is a displacement along the vehicle longitudinal direction F rather than a displacement along the vehicle width direction W. Therefore, it is displaced gently in the vehicle width direction W. For this reason, the displacement is substantially along the front-rear direction F. In other words, the rotational displacement of the front end portion 25 is substantially the same as the sliding direction.

  A sensor 60 is provided at the front end 25. When the sensor 60 has an obstacle between the slide door main body 21 and the edge of the rear opening 15 in order to prevent an occupant or the like from being caught between the slide door main body 21 and the rear opening 15. Has a function of detecting the presence of the obstacle.

  For example, the slide door device 20 includes a stop mechanism that stops the displacement (rotation displacement, slide displacement) of the slide door main body 21. Based on the detection result of the sensor 60, the stop mechanism can stop the displacement of the slide door main body 21.

  The sensor 60 only needs to be able to detect the displacement direction of the front end portion 25 of the slide door body 21. For this reason, the detection direction of the sensor 60 is substantially along the longitudinal direction of the vehicle body.

  As shown in FIG. 13, the displacement of the rear end portion 26 in the vicinity of the rear opening 15 by the link mechanism 40 is substantially along the vehicle width direction.

  Next, the rail member 34 of the slide door main body 21 will be described in detail. As shown in FIG. 11, the posture of the slide door main body 21 at the fully open position P2 is substantially parallel to the posture of the slide door main body 21 in the fully closed position P1. For this reason, in order to displace from the oblique posture at the protruding position P3 to the parallel posture, the guide portion 35 of the rail member 34 faces outward in the vehicle width direction in a state where the slide door body 21 is attached to the vehicle body 11. Curved to be convex. For this reason, when the slide of the slide door main body 21 is guided by the guide portion 35, the slide trajectory of the slide door main body 21 curves along the curve of the guide portion 35.

  In other words, the shape of the guide portion 35 is curved so that the oblique posture of the slide door body 21 at the protruding position P3 is substantially parallel to the posture at the fully closed position P1 at the fully open position P2.

  In the present embodiment, the guide portion 35 is curved in the entire region (between one end and the other end in the extending direction). For this reason, when the slide of the slide door main body 21 is guided, the slide locus of the slide door main body 21 is all curved. For this reason, in this embodiment, while the guide part 35 functions as a guide part said by this invention, it is also a curved part said by this invention.

  However, it is not limited to this. The guide portion 35 is a portion that guides the slide door body 21 so as to slide linearly instead of being curved, and a portion that guides the slide door body 21 so as to slide in a curved shape (a portion that curves so as to protrude toward the outside of the vehicle body). The structure which has these may be sufficient. The portion that is guided so as to slide in a curved shape is a curved portion referred to in the present invention. That is, the guide portion has a structure having a curved portion as referred to in the present invention.

  As shown in FIGS. 3 to 5, the rotation link mechanism 50 includes a first arm 52 and a second arm 53 that are rotatably connected to each other by a rotation shaft 51. And the movable base 33. The first arm 52 is disposed on the fixed side base 36 side. The second arm 53 is disposed on the movable base 33 side.

  One end of the first arm 52 is connected to the fixed base 36 by a rotation shaft 55 so as to be rotatable around the rotation shaft 55. One end of the second arm 53 is rotatably fixed to the movable base 33 via an extendable boot 56 made of an elastic member such as rubber.

  Since the rotation shafts 51 and 55 are parallel to the rotation shafts 44 to 47 of the link mechanism 40, the rotation link mechanism 50 can be displaced in accordance with the rotation displacement of the slide door body 21, and the slide door body 21 displacements are supported.

  Next, the operation of the sliding door device 20 will be described. First, the operation of opening the slide door body 21 at the fully closed position P1 to the fully open position P2 will be described. First, an occupant operates a door knob or the like to release the holding of the sliding door main body 21 and the vehicle body 11 (holding by a latch mechanism or the like).

  Next, the operator urges the slide door body 21 in the sliding direction. When the operator is in the vehicle, the slide door body 21 is pushed in the substantially sliding direction from the inside of the vehicle to the outside. When the operator is outside the vehicle, the slide door main body 21 is pulled in a substantially sliding direction toward the outside of the vehicle.

  As a result, the direction of rotation by the link mechanism 40 in the vicinity of the rear opening 15 of the slide door main body 21 and the urged direction are substantially the same. For this reason, the slide door body 21 is smoothly rotated and displaced to the protruding position P3.

  Even if the slidable door body 21 reaches the protruding position P3, the occupant sets the urging direction of the slidable door body 21 as it is substantially in the longitudinal direction of the vehicle body (sliding direction).

  After the rotational displacement to the projecting position P3, the slide door body 21 slides along the outer surface 16 toward the rear of the vehicle body. Since the direction in which the urging force is applied to the slide door main body 21 (operation direction by the operator) is substantially the same as the slide direction (substantially front-rear direction F), the slide door main body 21 smoothly moves from rotational displacement to slide displacement. Transition.

  At this time, since the slide door main body 21 slides along the guide part 35, the slide locus | curve curves toward the vehicle interior, as shown in FIG. When the slide door body 21 is slid to the fully open position P2, the opening operation is finished.

  The operation of moving the slide door body 21 at the fully open position P2 to the fully closed position P1 may be the reverse of the above operation.

  In the slide door device 20 configured as described above, the displacement direction of the front end portion 25 of the slide door main body 21 in the vicinity of the rear opening 15 is substantially the vehicle body front-rear direction. That is, it becomes a substantially sliding direction.

  For this reason, the direction of the force (pushing or pulling) applied to displace the slide door body 21 is substantially the sliding direction from the fully closed position P1 to the protruding position P3 and from the protruding position P3 to the fully open position P2. It's okay. The same applies to the case where the slide door body 21 is closed. As a result, the operation for opening and closing the slide door body 21 is simplified.

  Furthermore, since the displacement direction of the slide door body 21 between the fully closed position P1 and the fully open position P2 is a substantially slid direction (substantially vehicle body front-rear direction) and substantially one direction, the shape of the door knob of the slide door body 21 Is not required to have a shape suitable for moving the slide door body 21 in a plurality of directions (vehicle width direction, vehicle body longitudinal direction). For this reason, since the shape of a doorknob can be simplified, it can suppress that cost rises.

  Further, since the displacement direction of the front end portion 25 of the slide door main body 21 in the vicinity of the rear opening 15 is substantially along the longitudinal direction of the vehicle body, for example, a load is input from the front due to a collision of the automobile 10 and the front door device 13. Even if the front door main body 14 is displaced rearward, the sliding door main body 21 is prevented from being prevented from being opened and closed.

  This point will be specifically described. When the front door main body 14 of the front door device 13 moves rearward, it is conceivable that the rear edge portion of the front door main body 14 overlaps the slide door main body 21 in the vehicle width direction W. However, the slide door main body 21 is displaced in the front-rear direction of the vehicle body in the vicinity of the rear opening 15.

  For this reason, even if the front door main body 14 of the front door device 13 moves rearward, the opening / closing direction of the slide door main body 21 (direction of rotational displacement by the link mechanism 40) and the front door main body 14 do not easily overlap. The obstruction of the opening / closing operation of the main body 21 is suppressed.

  Moreover, since the opening / closing operation | movement of the slide door main body 21 is suppressed, it is not necessary to provide the slide door main body 21 with the structure which prevents the front door main body 14 comprised with a rubber member etc. from entering. For this reason, an increase in the cost of the sliding door device 20 can be suppressed.

  Thus, in the sliding door apparatus 20 of this embodiment, cost can be restrained low, making opening and closing operation easy.

  In the present embodiment, the slide door device 20 has a structure in which the slide door body 21 slides toward the vehicle body rear side F1 when the slide door body 21 is opened. However, it is not limited to this. For example, the slide door device 20 may have a structure in which the slide door body 21 slides toward the vehicle body front side F2 when the slide door body 21 is opened.

  In this case, the rear link member 42 serves as the first link member referred to in the present invention, and the front link member 41 functions as the second link member referred to in the present invention. This is because the front side of the vehicle body is the front side in the sliding direction. The lengths of the first to fourth rotating shafts 44 to 47 are set so as to satisfy L1> L2> L3> L4. A similar effect can be obtained with such a structure.

  Further, in the structure in which the slide door main body 21 slides to the vehicle body front side F2 when the slide door main body 21 is opened, the slide door main body 21 is in the fully closed position at the instantaneous rotation center C (intersection of virtual lines V1 and V2). In the state, the link mechanism 40 is disposed in the vehicle width direction W away from the outer direction W1 and on the rear side of the link mechanism 40.

  In the state where the slide door body 21 is in the protruding position and the fully open position, the instantaneous rotation center C is the outward direction W1 of the link mechanism 40 and is ahead of the position of the instantaneous rotation center in the fully closed position. Placed in. In the state from the fully closed position toward the protruding position, the instantaneous rotation center C is a position away from the link mechanism 40 in the outward direction W1, and gradually moves forward and outward in the vehicle width direction.

  As described above, in the slide door device, the length between the axis lines of the respective rotation shafts of the first and second link members constituting the link mechanism (in the present embodiment, L1 to L4) is unequal. And the momentary rotation center is a position away from the fully closed position in the vehicle body inside / outside direction toward the protruding position (in this application, the outside direction in the vehicle width direction) with respect to the link mechanism, and A similar effect can be obtained when the structure is arranged on the front side in the closing direction of the sliding direction of the door member.

Various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the above-described embodiments.
