Description

  The present invention is a link mechanism that is attached to a vehicle body and includes a linear slide rail that extends in the sliding direction of the slide door, and a roller that can roll along the slide rail, and is coupled to the slide door. The present invention relates to a support structure for a sliding door of a vehicle having

  The slide door is configured to be slidable in the vehicle front-rear direction along the vehicle body at a slide position that is separated from the vehicle body by a certain distance in the vehicle width direction. Further, the sliding door is fully closed when the sliding door is housed in the peripheral recess of the door opening of the vehicle body. For this reason, in the vicinity of the fully closed position of the slide door, the slide door moves toward the inside in the vehicle width direction from the slide position to the fully closed position. For this reason, the slide rail into which the roller of the slide door is fitted is generally formed to bend obliquely inward in the vehicle width direction between the fully closed position and the fully closed position in accordance with the slide locus of the slide door. Is. The slide rail is provided above and below the door opening of the vehicle body. Here, in the vehicle described in Patent Document 1, the slide rail on the upper side of the door opening is formed in a straight line due to the restriction by the roof structure of the body. For this reason, the upper bracket of the slide door is connected to the slide rail via a link mechanism having a roller.

  As shown in FIG. 10, the link mechanism 100 described in Patent Document 1 includes a linear first link 101 and a second link 102 formed in a substantially plane V shape. The one end 101t and the one end 102t of the second link 102 are connected so as to be relatively rotatable. The other end of the first link 101 is connected to the end of the upper bracket 105 of the slide door (not shown) by a connecting pin 101z so as to be horizontally rotatable. The upper bracket 105 is formed with a slit portion 105s extending in the vehicle front-rear direction, and a rotation center pin 102p provided at a corner portion of the second link 102 moves along the slit portion 105s. It is fitted in a possible state. The other end 102x of the second link 102 is provided with a single roller 102r, and the roller 102r can roll along a linear slide rail 107 attached to a vehicle body (not shown). It is configured as follows. Here, the roller 102r of the second link 102 is configured to come into contact with the rail end 107e of the slide rail 107 in a state where the slide door is slid to the vicinity of the fully closed position.

  With the above configuration, when the sliding door slides in the closing direction and the roller 102r of the second link 102 comes into contact with the rail end 107e of the slide rail 107 in the vicinity of the fully closed position, the second link 102 moves to the left about the roller 102r. It will turn. As a result, the sliding door (upper bracket 105) moves in an oblique direction so as to approach the vehicle body (slide rail 107) as the second link 102 rotates to the left. Further, as the second link 102 rotates to the left, the first link 101 rotates to the right about the connecting pin 101z. For this reason, even if the upper slide rail 107 is formed in a straight line shape, the upper portion of the slide door moves to a fully closed position along a predetermined locus R.

Japanese Patent Laid-Open No. 2-60825

  However, in the above-described sliding door link mechanism 100, when the second link 102 rotates to the left when the sliding door slides to the fully closed position, as shown by the two-dot chain line in FIG. The connecting portions 101t and 102t with the two links 102 protrude toward the slide door. For this reason, it is necessary to provide a recess for accommodating the connecting portions 101t and 102t of the first link 101 and the second link 102 on the slide door side. This complicates the shape of the slide door and restricts the shape of the slide door.

  The present invention has been made to solve the above-mentioned problems, and the problem to be solved by the present invention is to reduce the dimension of the link mechanism in the vehicle width direction at the fully closed position of the slide door, and to slide the slide mechanism. This is to make the storage space for the link mechanism on the door side or body side as small as possible.

  The above-described problems are solved by the inventions of the claims. The invention of claim 1 is attached to a body of a vehicle, and includes a linear slide rail extending in a sliding direction of the slide door, and a roller that can roll along the slide rail, and is coupled to the slide door. The link mechanism includes a plurality of rollers arranged at regular intervals along the slide rail, and the link mechanism is configured to be rotatable around the rollers. And a distance in the vehicle width direction between the slide door and the slide rail is changed in accordance with an inclination angle of the link with respect to the slide rail. In the process of moving to the closed position, the link rotates horizontally around the roller to a position where it overlaps the virtual extension line of the slide rail.

  According to the present invention, in the process in which the slide door moves to the fully closed position, the link of the link mechanism is configured to rotate horizontally to a position overlapping the virtual extension line of the slide rail around the roller. For this reason, in a state where the slide door is in the fully closed position, the link of the link mechanism is disposed on the extended line of the slide rail in a plan view, and the dimension of the link mechanism in the vehicle width direction is minimized. Therefore, the storage space for the link mechanism on the slide door side or the body side can be made as small as possible.

  According to the invention of claim 2, the link mechanism has a first roller at one end and the other end connected to the slide door in a state where the other end is rotatable and a second roller at one end, and the other end. Comprises a second link connected to the sliding door in a rotatable state, and a connecting link for connecting the first roller and the second roller, and when the sliding door slides to the vicinity of the fully closed position, Either the first roller or the second roller abuts against the rail end of the slide rail, the rolling of both rollers stops, and the first link and the second link are moved while the slide door moves to the fully closed position. A link rotates horizontally around each roller.

  According to the invention of claim 3, the distance between the first roller and the second roller of the link mechanism is set equal to the distance between the connecting portion of the first link and the connecting portion of the second link in the slide door. For this reason, the first link and the second link are parallel to each other, and both links can be overlapped vertically at the fully closed position of the slide door.

  According to the fourth aspect of the present invention, in the state where the roller rolls along the slide rail, the angle of the link with respect to the slide rail is configured to be substantially a right angle. For this reason, the slide door can be slid with the distance in the vehicle width direction between the slide rail and the slide door being maximum.

  According to the invention of claim 5, the plurality of rollers are housed inside the slide rail, and the link including the roller that contacts the rail end of the slide rail has a link that is centered on the roller. An outer roller is provided that can roll along the outer surface of the rail end when horizontally rotating to a position overlapping the virtual extension line. That is, since the rail end of the slide rail is sandwiched between the inner roller and the outer roller of the slide rail while the slide door is in the fully closed position, relative movement of the link mechanism with respect to the slide rail is prohibited.

  According to the invention of claim 6, the link mechanism includes the spring material biased so as to hold the link at a position overlapping the virtual extension line of the slide rail or a position substantially perpendicular to the slide rail. . For this reason, the slide door can be stably supported at the fully closed position or the slide position by the link mechanism.

  According to the present invention, the dimension of the link mechanism in the vehicle width direction can be reduced at the fully closed position of the slide door. For this reason, the storage space for the link mechanism on the slide door side or the body side can be made as small as possible.

Here, the length dimension of the upper slide rail 22 is set in accordance with the slide range of the slide door 15.

<About the upper support structure of the sliding door 15>
As shown in FIG. 4 and the like, brackets 50 are fixed to the inner panel 151 constituting the slide door 15 by bolts and nuts BN at a plurality of positions on the front and rear sides. As shown in FIGS. 3 and 4, the bracket 50 is formed in an L-shaped vertical section by a vertical plate portion 51 and a horizontal plate portion 52 that are long in the front and rear direction. And the vertical board part 51 of the bracket 50 is being fixed to the inner panel 151 of the slide door 15 with the said volt | bolt and nut BN, as shown in FIG. In the horizontal plate portion 52 of the bracket 50, a position near the center front is a high place flat part 52u, and a position near the center rear is a low place flat part 52d. As shown in FIGS. 3 and 4, the base end portion 41 f of the first link 41 of the link mechanism 40 is horizontally aligned by the first connecting mechanism 55 on the flat portion 52 u of the horizontal plate portion 52 of the bracket 50. It is connected in a rotatable state. In addition, the base end portion 43f of the second link 43 of the link mechanism 40 is connected to the lower side flat portion 52d of the horizontal plate portion 52 of the bracket 50 in a state in which the second connection mechanism 56 can be relatively rotated horizontally. Yes.

  As shown in FIG. 3, the link mechanism 40 includes a first link 41 and a second link 43 that are formed in a strip shape and have the same length, and a connecting link 44 that connects the distal ends of the links 41 and 43. It is configured. As described above, the first link 41 is connected to the lateral plate portion 52 of the bracket 50 in a state in which the base end portion 41f is relatively rotatable, and a rotation stopper 41s is connected to the front end portion of the base end portion 41f. Is formed so as to protrude in a direction perpendicular to the first link 41. As shown in FIG. 3, the rotation stopper 41 s is configured so that the first link 41 contacts the vertical plate portion 51 of the bracket 50 in a state of being perpendicular to the upper slide rail 22. In other words, the rotation stopper 41 s prohibits the first link 41 from rotating right about the first coupling mechanism 55 from the state shown in FIG.

  As shown in FIG. 4, a vertical axis 41j is erected at the tip of the first link 41, and the first roller 401 rotates about the axis of the vertical axis 41j at the upper end position of the vertical axis 41j. They are connected freely. As shown in FIGS. 3 and 4, the first roller 401 is fitted in a rollable state along the upper slide rail 22 on the body 10 side. Further, the first link 41 has a central vertical axis 41r erected at a position closer to the center with respect to the first roller 401, and the outer roller 403 is positioned at the upper end position of the central vertical axis 41r. The shaft 41r is connected so as to be rotatable around the axis of the shaft 41r. As shown in FIG. 3, the outer roller 403 is disposed at a position where it can come into contact with the roller rolling surface 222 of the rail end 220 of the upper slide rail 22 from the outside. The outer roller 403 is configured to roll along the roller rolling surface 222 when the first link 41 rotates left about the first roller 401 in FIG.

  As described above, the second link 43 of the link mechanism 40 is connected to the lateral plate portion 52 of the bracket 50 so that the base end portion 43f is relatively rotatable. As shown in FIG. 3, a vertical axis 43j is erected at the tip of the second link 43, and the second roller 402 is arranged around the axis of the vertical axis 43j at the upper end position of the vertical axis 43j. It is connected in a freely rotatable state. The second roller 402 is fitted in a rollable state along the upper slide rail 22 on the body 10 side. Here, as shown in FIG. 8, the second roller 402 of the second link 43 is held at the same height as the first roller 401 and the outer roller 403 of the first link 41. The vertical axis 41j of the first roller 401 and the vertical axis 43j of the second roller 402 are connected by a connecting link 44 so as to be relatively rotatable horizontally. For this reason, the connecting link 44 is always held at a position where the center line in the length direction overlaps the center line in the length direction of the upper slide rail 22.

  As shown in FIG. 3, the connection link 44 includes the first roller 401 so that the distance between the first roller 401 and the second roller 402 is equal to the distance between the first connection mechanism 55 and the second connection mechanism 56. The vertical axis 41j is connected to the vertical axis 43j of the second roller 402. For this reason, the first link 41 and the second link 43 can be horizontally rotated around the first roller 401 and the second roller 402 while being parallel to each other. Further, as shown in FIG. 3, the second link 43 is positioned at a right angle to the connection link 44 or between the distal ends of the connection link 44 and the second link 43, or as shown in FIGS. 6 to 8. A spring material 45 is provided so as to be able to hold the second link 43 at a position overlapping the connecting link 44. Here, a state in which the first link 41 and the second link 43 are perpendicular to the upper slide rail 22 (connection link 44) (see FIG. 3) is a developed state of the link mechanism 40, and the first link 41 and the second link 43 are The state (FIGS. 6 to 8) in which the two links 43 overlap with the virtual extension line of the upper slide rail 22 (connection link 44) is the folded state of the link mechanism 40.

<Operation of the upper support structure of the sliding door 15>
In the state where the slide door 15 is in the fully open position, as shown in FIG. 4, the front upper portion 15 u of the slide door 15 has the link mechanism 40 in the unfolded state, and the first roller 401 and the second roller provided in the link mechanism 40. And the upper slide rail 22 on the body 10 side. When the slide door 15 is closed from this state, the first roller 401 and the second roller 402 of the link mechanism 40 are rolled forward along the upper slide rail 22 to slide the slide door 15 forward. At this time, the link mechanism 40 is held in the deployed state by the spring force of the spring member 45 and the action of the rotation stopper 41s. In this state, when the slide door 15 reaches the vicinity of the fully closed position as shown in FIG. 2, the first roller 401 comes into contact with the rail end 220 of the upper slide rail 22 as shown in FIG. 3. As a result, the rolling of the first roller 401 and the second roller 402 is stopped, and the first roller 401 and the second roller 402 are held at the front end position of the upper slide rail 22.

  When the slide door 15 moves obliquely leftward (inward in the vehicle width direction) from this state, the first link 41 and the second link 43 of the link mechanism 40 are in parallel with each other as shown in FIG. It rotates counterclockwise around the first roller 401 and the second roller 402 against the spring force of the material 45. At this time, since the rotation stopper 41s of the first link 41 is separated from the vertical plate portion 51 of the bracket 50, the rotation stopper 41s does not work. By the left rotation of the first link 41 and the second link 43, the inclination angle of the first link 41 and the second link 43 with respect to the upper slide rail 22 gradually decreases, and between the upper slide rail 22 and the slide door 15. The distance in the vehicle width direction gradually decreases.

  As the first link 41 rotates to the left, the outer roller 403 provided on the first link 41 rolls along the roller rolling surface 222 of the rail end 220 of the upper slide rail 22. Accordingly, the rollers 401 and 402 of the first link 41 and the second link 43 are held at the front end position of the upper slide rail 22. 6 to 8, the first link 41 and the second link 43 are turned to the left on the extension line of the upper slide rail 22 in plan view, that is, the link mechanism 40 is folded. The sliding door 15 is held in the fully closed position in the folded state. For this reason, when the slide door 15 is in the fully closed position, the dimension of the link mechanism 40 in the vehicle width direction is minimized as shown in FIG. Therefore, the storage space of the link mechanism 40 can be made as small as possible. Further, since the outer roller 403 provided on the first link 41 presses the rail end 220 of the upper slide rail 22 from the front, the rolling of the first roller 401 and the second roller 402 with respect to the upper slide rail 22 is prohibited.

  Next, when the sliding door 15 is opened, if the sliding door 15 moves obliquely from the fully closed position (see FIG. 6 and the like) to the right rear (outward rear in the vehicle width direction), the first link 41 and the second link 41 of the link mechanism 40 are moved. The link 43 is pulled right rearward by the bracket 50 of the slide door 15 via the first connection mechanism 55 and the second connection mechanism 56. For this reason, the first link 41 and the second link 43 of the link mechanism 40 rotate clockwise around the first roller 401 and the second roller 402 against the spring force of the spring material 45 as shown in FIG. To do. Thereby, the inclination angles of the first link 41 and the second link 43 with respect to the upper slide rail 22 are gradually increased, and the distance in the vehicle width direction between the upper slide rail 22 and the slide door 15 is gradually increased. Further, as the first link 41 rotates to the right, the outer roller 403 of the first link 41 rolls along the roller rolling surface 222 of the rail end 220 of the upper slide rail 22. Therefore, the rollers 401 and 402 of the first link 41 and the second link 43 are held at the front end portion of the upper slide rail 22.

  As shown in FIG. 3, the rotation stopper 41 s of the first link 41 slides in a state where the first link 41 and the second link 43 are rotated to the right until the first link 41 and the second link 43 are substantially perpendicular to the upper slide rail 22. The first link 41 and the second link 43 are prohibited from rotating to the right by contacting the vertical plate portion 51 of the bracket 50 of the door 15. That is, the link mechanism 40 is in the deployed state, and the link mechanism 40 is held in the deployed state by the spring force of the spring material 45. In this state, as shown in FIGS. 3 and 4, the distance in the vehicle width direction between the upper slide rail 22 and the slide door 15 is maximized, and the first roller 401, the second roller 402, and the outer roller of the link mechanism 40. 403 can roll along the upper slide rail 22. That is, the slide door 15 can slide backward along the right side surface of the body 10 to the fully open position.

<Advantages of the sliding door support structure for a vehicle according to this embodiment>
According to the vehicle slide door support structure according to the present embodiment, in the process in which the slide door 15 slides to the fully closed position, the links 41 and 43 of the link mechanism 40 virtually extend the upper slide rail 22 around the rollers 401 and 402. It is configured to rotate horizontally until the line overlaps the line. Therefore, in the state where the slide door 15 is in the fully closed position, the links 41 and 43 of the link mechanism 40 are arranged on the extension line of the upper slide rail 22 in a plan view, and the dimension of the link mechanism 40 in the vehicle width direction is the smallest. become. Therefore, the storage space for the link mechanism on the slide door 15 side or the body 10 side can be minimized.

  The distance between the first roller 401 and the second roller 402 of the link mechanism 40 is such that the connecting portion (first connecting mechanism 55) of the first link 41 and the connecting portion (second connecting portion) of the second link 43 in the slide door 15. It is set equal to the distance between the mechanisms 56). For this reason, the first link 41 and the second link 43 are parallel to each other, so that the links 41 and 43 can be overlapped vertically in the fully closed position of the slide door 15. Further, in a state where the rollers 401 and 402 are rolling along the upper slide rail 22, the angles of the first and second links 41 and 43 with respect to the upper slide rail 22 are substantially perpendicular. For this reason, the slide door 15 can be slid with the distance in the vehicle width direction between the upper slide rail 22 and the slide door 15 being the maximum.

  Further, the first link 41 is moved along the roller rolling surface 222 of the rail end 220 when the first link 41 rotates horizontally around the first roller 401 to a position on the extension line of the upper slide rail 22. An outer roller 403 that can be rolled is provided. For this reason, since the rail end 220 of the upper slide rail 22 is sandwiched between the first roller 401 and the outer roller 403 while the slide door 15 is in the fully closed position, the relative slide of the link mechanism 40 with respect to the upper slide rail 22 is prevented. It is forbidden. Further, the link mechanism 40 can be stably held in the expanded state or the folded state by the action of the spring material 45.

<Example of change>
Here, the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist of the present invention. For example, in the present embodiment, an example in which the link mechanism 40 includes the first link 41, the second link 43, and the connection link 44 has been described. However, for example, a configuration in which the second link 43 is omitted and the strength of the first link 41 is improved is also possible. Moreover, although the coil spring was illustrated as the spring material 45, it is also possible to use a leaf | plate spring etc., for example. In the present embodiment, the upper support structure of the slide door 15 is illustrated, but the present invention can also be applied to the lower support structure of the slide door 15 that supports the lower part of the slide door 15 with the lower slide rail 24. is there. Moreover, although the example which applies this invention to the right side slide door mechanism of a vehicle was shown, it is also possible to apply this invention to a left side slide door mechanism.
