Description

  The present invention relates to a vehicular power slide door device for automatically opening and closing a boarding / alighting opening on a side of a vehicle body.

  In recent years, as a door of a vehicle such as an automobile, a slide door is slidably provided on the side surface of the vehicle, and the slide door is automatically opened and closed by an electric motor by operation of a switch or the like disposed in a driver's seat or the like, and an occupant gets on and off. There are an increasing number of vehicles equipped with power sliding door devices that enhance convenience.

  In this type of power slide door device, generally, an upper rail, a lower rail, and a center rail are disposed on the upper and lower portions of the opening formed in the vehicle body and the rear outer wall of the vehicle body, and the slide door is provided on the upper rail, the lower rail, and the center rail. By engaging the upper roller, the lower roller and the center roller attached to the front end upper part, the front end lower part and the rear end center part, respectively, the slide door is slid along the vehicle body when the slide door is opened and closed.

  By the way, when trying to use the power slide door device for a light four-wheeled vehicle or the like, there is no dimensional allowance for arranging the center rail on the rear outer wall of the vehicle body. For this reason, the center rail is arranged on the slide door side. There are cases where it is unavoidable. As what arrange | positions such a center rail in a slide door, what was described in patent document 1, for example is known.

  In the one described in Patent Document 1, a guide roller that engages with a center rail disposed on the slide door side is supported by a column connected to the vehicle body side, and is supported on both ends of the center rail by this column. The both ends of the wire stretched around the integrated pulley (front pulley and rear pulley) are coupled, and the wire is driven by the slide motor (36), so that the guide roller coupled to the wire is moved along the center rail. The sliding door is opened and closed.

On the other hand, in this type of power sliding door device, when the sliding door is opened, the sliding door is moved away from the vehicle body side. When the sliding door is closed, the sliding door sinks into the vehicle body side and the outer wall surface of the vehicle body and the outer wall surface of the sliding door. Therefore, the upper rail, lower rail, and center rail that slidably guide the sliding door are composed of a straight portion and a curved portion, but the wire is moved across the straight portion and the curved portion. Since the effective length of the wire changes when the wire is bent, it is necessary to absorb the change in the effective length and prevent the wire from slackening. A configuration for preventing such loosening of the wire is described in Patent Document 2, for example.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a power sliding door device for a vehicle according to the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a vehicle 11 equipped with a power slide door device 10. An upper rail 17 is disposed on an upper part of a boarding opening 15 formed in a vehicle body 14 that is opened and closed by a slide door 13. A lower rail 18 is disposed below the boarding opening 15. Further, as shown in FIG. 2, a center rail 19 substantially parallel to the upper rail 17 and the lower rail 18 is provided inside the slide door 13.

  As shown in FIG. 2, corner portions 17a and 18a that are curved inside the vehicle body 14 are formed on the front end sides of the upper rail 17 and the lower rail 18, and the rear end of the center rail 19 provided on the slide door 13 side. On the side, a curved corner portion 19a is formed inside the vehicle body 14. When the sliding door 13 is slidably supported with respect to the vehicle body 14 along the rails 17, 18 and 19, and the sliding door 13 moves to the front side of the vehicle body 14 and the entrance opening 15 is closed, Due to the corner portions 17 a, 18 a, 19 a of the rails 17, 18, 19, the slide door 13 sinks inside the vehicle body 14 so that the outer wall surface of the vehicle body 14 coincides with the outer wall surface of the slide door 13.

  An upper roller and a lower roller (not shown) that engage with the upper rail 17 and the lower rail 18 are supported on the front end upper portion and the front end lower portion of the slide door 13, respectively, and a roller guide (described later) that engages with the center rail 19 on the vehicle body 14 side. The apparatus is supported, whereby the slide door 13 is guided along the rails 17, 18, 19 and slid along the outer wall surface of the vehicle body 14.

  FIG. 3 shows the entire power sliding door device 10 viewed from the inside of the sliding door 13 (inside the vehicle compartment), and shows a state in which the trim (lining) of the sliding door 13 is removed. The direction is the front of the vehicle 11, and the right direction is the rear of the vehicle 11. 3 shows a state before the center rail 19 is attached, and the center rail 19 is omitted. 4 is a plan view of the power slide door device 10 shown in FIG. 3 as viewed from above.

  3 and 4, the slide door 13 is provided with a wire take-up drum 23 driven by an electric motor 22 capable of rotating in the forward and reverse directions at a substantially central portion in the vehicle front-rear direction. At both ends, a front pulley 24 and a rear pulley 25 are provided as driven pulleys. The wire take-up drum 23 is supported in a drum cover 27 attached to the slide door 13 so as to be rotatable around a horizontal axis perpendicular to the vehicle front-rear direction. Further, the front pulley 24 and the rear pulley 25 are respectively supported by the front pulley bracket 28 and the rear pulley bracket 29 attached to the slide door 13 so as to be rotatable around a vertical axis perpendicular to the rotation axis of the wire take-up drum 23. Has been. The rear pulley bracket 29 is formed with a pair of wire guide portions 29 a and 29 b that are curved along the corner portion 19 a (see FIG. 2) of the center rail 19.

  The first wire 31 having one end connected to the wire take-up drum 23 is stretched over the front pulley 24 and connected to a tensioner device 33 having a configuration described later while being guided by the wire guide portion 29a. The second wire 32 having one end connected to the wire take-up drum 23 is guided by the wire guide portion 29b and is passed over the rear pulley 25, and the other end is connected to the tensioner device 33. Then, when the wire winding drum 23 is rotated forward or reversely by the electric motor 22, one of the first and second wires 31, 32 is wound and the other is fed.

  As shown in FIGS. 6 and 7, the tensioner device 33 is a first member having a substantially rectangular parallelepiped shape in which holding shafts 35 and 36 that hold the other ends of the first and second wires 31 and 32 are slidably housed. And a second tensioner housing 37,38. The first and second tensioner housings 37, 38 accommodate coil springs 39, 40 interposed between the tensioner housings 37, 38 and the holding shafts 35, 36, and are held by these coil springs 39, 40. The shafts 35 and 36 are biased in directions opposite to each other, and tension is applied to the first and second wires 31 and 32 connected thereto.

  Here, in the tensioner device 33, as shown in FIG. 7, the first and second tensioner housings 37, 38 are arranged in the extending direction of the first and second wires 31, 32, and the first and second wires. In the direction in which the wires 31 and 32 overlap, they are superposed in the vertical direction with a predetermined offset O1 so that the amount of movement of the tensioner device 33 relative to the attachment spans of the front pulley 24 and the rear pulley 25 can be increased. I have to. That is, as shown by the solid line in FIG. 8A, the relative movement amount of the second tensioner housing 38 with respect to the rear pulley 25 is up to the position in contact with the rear pulley 25. At this time, the first tensioner housing 37 is movable to the outside (rear) of the second tensioner housing 38 by an offset amount O1. Similarly, the amount of relative movement of the first tensioner housing 37 with respect to the front pulley 24 is up to the point of contact with the front pulley 24 as indicated by the two-dot chain line in FIG. 38 is movable to the outside (front) of the first tensioner housing 37 by the offset amount O1.

  Further, by arranging the first and second tensioner housings 37 and 38 in the vertical direction, the dimension of the tensioner device 33 in the vehicle width direction is reduced, and the thickness of the slide door 13 is not increased. Note that the tensioner device 33 is arranged by offsetting that the first and second tensioner housings 37 and 38 are arranged in a state where they are overlapped in the vertical direction of the vehicle 11 and are shifted in the front-rear direction of the vehicle 11. However, due to a design change, for example, a state in which the vehicle 11 is shifted in the front-rear direction of the vehicle 11 while being overlapped in the left-right direction (vehicle width direction) may be used as an offset.

  As shown in FIG. 6, the vehicle body 14 is provided with a roller guide device 50 that guides the center rail 19 attached to the slide door 13. The roller guide device 50 includes a hinge arm 55 that supports a pair of guide rollers 51 and 52 and a support roller 53, and the hinge arm 55 is fixed to the vehicle body 14 as shown in FIGS. 4 and 5. And pivotally supported by a pivot 57 around a vertical axis. The hinge arm 55 has a horizontal portion 55a that passes through an opening 58a formed in a trim (lining) 58 of the slide door 13, and the tip of the horizontal portion 55a is bent upward in the slide door 13 to be a vertical support portion. 55b, and a pair of guide rollers 51 and 52 are supported on the upper end of the vertical support portion 55b. The pair of guide rollers 51 and 52 sandwich the center rail 19 on both sides in the vehicle width direction and guide the center rail 19 attached to the slide door 13 so as to be slidable in the vehicle front-rear direction. A support roller 53 that supports the lower surface of the center rail 19 is supported on the vertical support portion 55 b of the hinge arm 55.

  A mounting bracket 60 to which the tensioner device 33 is attached is fixed to the vertical support portion 55 b of the hinge arm 55 by a mounting bolt 61. As described above, the first and second tensioner housings 37 and 38 are overlapped in the vertical direction on the mounting bracket 60 and are offset by a predetermined amount O1 in the front-rear direction of the slide door 13.

  As shown in FIG. 7, the mounting bracket 60 is notched in a V shape at the top, and has two protrusions 60a and 60b on both sides thereof, and bolt holes 60a1 and 60b1 are provided in these protrusions 60a and 60b. Yes. The mounting bracket 60 is fixed to the vertical support portion 55b of the hinge arm 55 by mounting bolts 61 that pass through the bolt holes 60a1 and 60b1.

  Next, the operation in the above configuration will be described. As shown in FIGS. 3 and 4, when the tensioner device 33 is located on the rear pulley 25 side, the slide door 13 is in a closed state, and in this closed state, as shown by a solid line in FIG. In addition, the second tensioner housing 38 connected to the second wire 32 wound around the rear pulley 25 is positioned before contacting the rear pulley 25, but is connected to the first wire 31. The first tensioner housing 37 is positioned behind the vehicle 11 by an offset amount O1 relative to the second tensioner housing 38. That is, the first tensioner housing 37 is moved rearward to a position where it overlaps the rear pulley 25.

  Under this closed state, one end of the second wire 32 is wound around the wire take-up drum 23, and the other end is connected to the spring 40 (see FIG. 7) in the second tensioner housing 38 via the rear pulley 25. (See below). Similarly, one end of the first wire 31 is wound around the wire take-up drum 23, and the other end receives the tension of the spring 39 (see FIG. 7) in the first tensioner housing 37 via the front pulley 24. ing.

  When the electric motor 22 is rotated in one direction in order to move the slide door 13 in the opening direction, the wire winding drum 23 is actuated in a direction in which the first wire 31 is wound and the second wire 32 is rewound. Thus, the slide door 13 supporting the front and rear pulleys 24 and 25 wound with the wires 31 and 32 is moved in the vehicle backward direction with respect to the tensioner device 33 attached to the vehicle body 14 side. Begins to open.

  When the sliding door 13 starts to open, the tensioner device 33 corresponds to the corner portion 19a formed on the center rail 19, so that the sliding door 13 starts opening while being operated away from the vehicle body 14. At this time, since the first and second tensioner housings 37 and 38 are in contact with the wire guide portions 29a and 29b of the rear pulley bracket 29, the trajectories of the first and second wires 31 and 32 change, Although the substantial lengths of the first and second wires 31 and 32 change due to the change in the trajectory, the length changes of the wires 31 and 32 are absorbed by the expansion and contraction of the springs 39 and 40, and the first and second wires 31 and 32 are absorbed. Due to the tension applied to the second wires 31 and 32, the first and second wires 31 and 32 are always held in a state without slack.

  When the tensioner device 33 corresponds to the straight portion of the center rail 19, the slide door 13 is linearly moved rearward of the vehicle, and the slide door 13 is fully opened (state of FIG. 5). When the slide door 13 is fully opened, the first tensioner housing 37 connected to the first wire 31 wound around the front pulley 24 is slid as shown by a two-dot chain line in FIG. The second tensioner housing 38 connected to the second wire 32 is offset relative to the first tensioner housing 37 by an offset amount O1. Only the sliding door 13 is positioned in front of the vehicle 11.

  Thereby, the moving distance L1 of the tensioner device 33 with respect to the slide door 13 can be increased by the offset amount O1 with respect to the opening / closing amount that can be taken when the tensioner device 33 is not offset.

  That is, normally, the maximum amount that can be taken as the opening / closing amount of the slide door 13 corresponds to the position A in front of the tensioner device 33 contacting the front pulley 24 and the rear pulley 25 as shown in FIG. Although the distance L2 is the distance L2 from the position B just before the contact, in the present embodiment, the tensioner device 33 is constituted by the offset first and second tensioner housings 37 and 38. In the closed state, the first and second wires 31 and 32 can be operated to a position where the first tensioner housing 37 overlaps the rear pulley 25, while in the fully opened state of the slide door 13, Actuate the first and second wires 31, 32 to a position where the two tensioner housings 38 pass over the front pulley 24 Door can be. As a result, the opening / closing amount of the slide door 13 becomes L1, and can be increased by the offset O1 of the first and second tensioner housings 37, 38 from the conventional opening / closing amount L2 of the slide door 13.

  As a result, even when the effective dimension of the sliding door 13 in the vehicle front-rear direction is relatively small, in other words, even when the attachment span L0 of the front pulley 24 and the rear pulley 25 cannot be increased, the moving distance (opening / closing amount) of the sliding door 13 L1 can be increased.

  When closing the slide door 13 from the open state, the electric motor 22 is rotated in the opposite direction. As a result, the wire take-up drum 23 winds up the second wire 32 and is operated in the direction of rewinding the first wire 31 to support the front and rear pulleys 24 and 25 around which the wires 31 and 32 are wound. The slide door 13 is moved in the vehicle forward direction with respect to the tensioner device 33 attached to the vehicle body 14 side, and the slide door 13 is closed.

  According to the above-described embodiment, the front pulley 24 and the rear pulley 25 that span the first and second wires 31 and 32 are provided on the slide door 13 side, and the first and second wires 31 and 32 are provided. Each end is wound around the wire take-up drum 23, and the other end of each of the first and second wires 31, 32 is connected to the tensioner device 33 at a position offset in the wire extension direction. Even when there is not enough room to dispose the center rail 19, the opening / closing amount of the slide door 13 can be secured, and the other ends of the first and second wires 31 and 32 are connected to the tensioner device 33. By connecting at an offset position, the opening / closing amount of the sliding door 13 is increased without being restricted by the mounting span of the front pulley 24 and the rear pulley 25. It can be.

  Therefore, it is also necessary for a vehicle that cannot take a large attachment span of the front pulley 24 and the rear pulley 25 because the sliding door 13 has a relatively small width in the front-rear direction, such as a mini four-wheel vehicle. The power slide door device 10 capable of securing the opening amount can be realized.

  According to the above-described embodiment, the tensioner device 33 includes the first and second tensioner housings 37 and 38 that are offset by a predetermined amount O1 in the direction in which the first and second wires 31 and 32 overlap each other. Since the springs 39 and 40 for applying tension to the first and second wires 31 and 32 are housed in the first and second tensioner housings 37 and 38, respectively, the wires 31 and 32 are separated into straight portions and curved portions. Regardless of the change in the effective length of the wire when it is moved over, the wires 31 and 32 can always be held in a slack-free state, and the sliding door 13 can be opened and closed smoothly.

  According to the above-described embodiment, the wire take-up drum 27 is supported so as to be rotatable around the horizontal axis, and the front pulley 24 and the rear pulley 25 are supported so as to be rotatable around the vertical axis. Since the first and second tensioner housings 37 and 38 are superposed in the vertical direction, the dimensions of the tensioner device 33 in the vehicle width direction are provided regardless of the configuration in which the first and second tensioner housings 37 and 38 are superposed. The thickness dimension of the slide door 13 can be reduced.

  By the way, in the state before the power slide door device 10 having the above-described configuration is attached to the vehicle body 14, there is no hinge arm 55 fixed to the vehicle body 14 side, so that the position of the tensioner device 33 can be restrained. When the power slide door device 10 is transported to the vehicle assembly process, for example, the tensioner device 33 is in a state of being only supported by the wires 31 and 32. Therefore, in the embodiment shown in FIGS. 9 to 12, the tensioner device 33 is installed in the power slide door device 10 when the power slide door device 10 is transported or the like (in the embodiment, the drum cover 27 is provided). ) Can be temporarily held.

  9 and 12, the synthetic resin drum cover 27 surrounding the wire take-up drum 23 has three hook portions 27a, 27b, 27c that engage with the two protrusions 60a, 60b of the mounting bracket 60. As shown in FIG. 10, the hook portions 27a, 27b, and 27c are formed in an integral shape and have an L-shape so as to hold the protrusions 60a and 60b. The drum cover 27 is integrally formed with an arm portion 27d as an elastically deformable portion that can be elastically deformed in the axial direction of the wire take-up drum 23, and a hemispherical engagement protrusion 27d1 is projected from the arm portion 27d. ing. The engaging protrusion 27d1 is disposed at a position corresponding to one bolt hole 60b1 of the mounting bracket 60 when the two protrusions 60a, 60b of the mounting bracket 60 are engaged with the hook parts 27a, 27b, 27c. The arm portion 27d is detachably engaged with the bolt hole 60b1 of the mounting bracket 60 by elastic deformation of the arm portion 27d. The arm portion 27d provided with the hook portions 27a, 27b, 27c and the engaging protrusion 27d1 is integrally formed when the drum cover 27 is molded with resin.

  As a result, when the tensioner device 33 is temporarily held on the drum cover 27, the tensioner device 33 with the mounting bracket 60 attached is used as the power slide door device 10 with respect to the wires 31 and 32. Inverted 180 degrees, and in that state, as shown in FIG. 12, when the two protrusions 60a, 60b of the mounting bracket 60 are inserted from above the drum cover 27 to engage with the hook portions 27a, 27b, 27c, The two protrusions 60a, 60b of the mounting bracket 60 are engaged with the hook parts 27a, 27b, 27c of the drum cover 27, and the arm part (elastically deforming part) 27d of the drum cover 27 is elastically deformed to be engaged. The portion 27d1 is engaged with the bolt hole 60b1 of the mounting bracket 60.

  Such engagement between the two protrusions 60a, 60b of the mounting bracket 60 and the hook parts 27a, 27b, 27c of the drum cover 27, and an engagement protrusion 27d1 of the bolt hole 60b1 of the mounting bracket 60 and the drum cover 27. With the engagement, the position of the tensioner device 33 is restrained in the three-dimensional direction of the vehicle 11 in the vertical direction, the front-rear direction, and the vehicle width direction, and is temporarily held by the slide door 13.

  At this time, the tensioner device 33 to which the mounting bracket 60 is attached is not kinked by the wires 31 and 32 no matter how many times the wires 31 and 32 are rotated. Thus, it is possible to easily temporarily hold the slide door 13 without any special member, and a special member for temporarily holding is unnecessary, so that the workability of the temporary holding can be improved and the resource can be saved.

  The temporary holding mechanism 70 is configured by the protrusions 60a and 60b and the bolt hole 60b1 formed on the mounting bracket 60 and the hook parts 27a, 27b and 27c, the arm part 27d and the engagement protrusion 27d1 formed on the drum cover 27. is doing.
