Description

  The present invention relates to a vehicle power slide door device for automatically opening and closing a slide door on a side surface of a vehicle.

  An example of a power slide door device that automatically opens and closes a slide door provided in a vehicle is described in Patent Document 1.

  In the vehicle described in Patent Document 1, a guide rail extends in the vehicle front-rear direction on the rear outer wall of the vehicle body behind the opening formed in the vehicle body. A sliding door is movably engaged with the guide rail via a door bracket. The vehicle body is provided with a drive device using a motor or the like as a drive source, and the cable drawn from the drive device in the vehicle front-rear direction is a door from the vehicle front-rear direction via reversing pulleys disposed at both ends of the guide rail. Guided by brackets. A cylindrical cable end is fixed to both ends of the cable, and the cable end is connected to a cable end support portion of a door bracket located in the guide groove. In addition, the drive device is provided with a tensioner mechanism that absorbs a change in the moving path length of the cable caused by the movement of the slide door and applies a tension for reliably operating the slide door. With such a configuration, the driving force of the driving device is transmitted to the sliding door via the cable, and the sliding door automatically opens and closes.

Here, one cable end is inserted from below or above into a connecting hole penetrating in the vertical direction of the cable end support portion and connected to the cable end support portion. However, when connecting the other cable end, it is necessary to assemble the cable against the tension because it is in a state where tension is applied to the cable to operate the sliding door reliably. Assembling is difficult. Therefore, in Patent Document 1, an assembly lever having a slit extending in the sliding direction is attached to a cable end support portion to which the other cable end is connected, and the cable end is temporarily held on the assembly lever and then rotated. Assemble. In this way, by using the assembly lever, when the other cable end is assembled, it is not necessary to assemble in the guide groove, and it is easy to assemble even when tension is applied to the cable. In other words, the power slide door device described in Patent Document 1 has a configuration that takes into account the assembly of the other cable end.
JP 2007-313942 A

  However, in the conventional vehicle power slide door device, assembling property of the other cable end is considered as described above, but one cable end is not considered. That is, since the cable end support portion is in the guide groove, the work of assembling one cable end to the door bracket needs to be performed in the guide groove. Moreover, it is necessary to connect the cable end to the connecting hole of the cable end support portion from below or above in the guide groove. Therefore, it is difficult to assemble one cable end.

  Therefore, the present invention has been made in view of such circumstances, and an object of the present invention is to provide a vehicle power slide door device in which assembling property between a cable and a door bracket is improved.

  In order to solve the above-mentioned problems, in the invention described in claim 1, the guide groove is arranged to extend in the vehicle front-rear direction in either the vehicle body or the slide door that opens and closes the entrance opening on the side surface of the vehicle body. A drive unit disposed on the provided guide rail side, a cable driven by the drive unit and extending along the guide rail, and slidably engaged with the guide rail to engage the vehicle body and the slide And a door bracket connected to the other end of the door, to which the end of the cable is connected. The door bracket is positioned in the guide groove and rolls relative to the guide rail. A rolling element that abuts freely, and is positioned outside or directly below the rolling groove and extending in the sliding direction of the door bracket. And a cable end supporting portion having a through hole, an end portion of the cable, and summarized in that an engaging portion for engaging the cable end supporting portion when being inserted into the through hole.

  With the above configuration, since the cable end support portion is located outside the guide groove, it is not necessary to assemble the cable in the guide groove when the cable is assembled to the door bracket, and the assemblability is improved. Since the engagement portion engages with the cable end support simply by inserting the end of the cable through the through-hole, the cable can be easily attached to the cable end support even when tension is applied to the cable. Can be assembled. In addition, since the end of the cable is supported directly above or below the rolling element, the difference in trajectory between the cable and the guide rail due to the movement of the door bracket is reduced, and the deflection of the cable can be suppressed. Assembling performance of the device can be improved and operation reliability can be secured.

According to a second aspect of the present invention, in the vehicle power slide door device according to the first aspect, the tensioner housing has an insertion hole through which the cable is inserted and has the engagement portion, and is housed in the tensioner housing. And a tensioner disposed between one end of the tensioner housing and one end of the cable and having an elastic member for applying tension to the cable in the sliding direction at the end of the cable. The gist is to connect the end of the cable to the door bracket by attaching it to the cable end support.

  With the above configuration, the tensioning direction of the tensioner matches the cable (tensioner) mounting direction. For example, when the cable is assembled to the cable end support, pulling the tensioner in the sliding direction resists the tension in the tensioner housing. Easy to assemble because the cable is pulled out from. Further, since the tensioner is provided at the end of the cable, it is not necessary to provide the tensioner inside the driving means, and the driving means can be made compact and simplified.

  According to a third aspect of the present invention, in the vehicle power slide door device according to the first or second aspect, the door bracket is inserted into the through-hole from a direction in which the end portions of the cables face each other. It has a restricting member that engages the cable end support portion and the end portion of the cable from the outside of the vehicle and restricts movement of the end portion of the cable relative to the cable end support portion in the sliding direction. And

  With the above configuration, the movement of the end portion of the cable in the sliding direction with respect to the cable end support portion can be further restricted by the restriction member. Therefore, the engagement between the cable end and the cable end regulating portion can be further strengthened, and the operation reliability of the vehicle power slide door device is improved.

  According to a fourth aspect of the present invention, in the power slide door device for a vehicle according to the third aspect, the door bracket has a base portion extending in the vehicle vertical direction and having a base through hole formed therein, and the cable. The end support portion is formed by bending and projecting from the base portion toward the vehicle inner side. The end support portion includes the through hole in which the end portion of the cable can be arranged in parallel in the vehicle width direction in the slide direction. The portion extends in the sliding direction, has a concave shape portion that is concave with respect to the vehicle vertical direction at the center of the sliding direction, and has the engaging portion at the tip thereof, and the regulating member is The gist of the invention is to have a bifurcated portion that engages with each concave-shaped portion and a fitting portion that fits into the base through hole.

  With the above configuration, the restricting member has a simple structure because the bifurcated part restricts the movement of the cable end in the sliding direction both upward and downward, and the fitting part restricts the start of the cable end support part in the sliding direction. The end portion of the cable and the cable end support portion can be fixed.

  ADVANTAGE OF THE INVENTION According to this invention, the power slide door apparatus for vehicles which improved the assembly | attachment property of a cable and a door bracket can be provided.

As shown in FIG. 3, a recessed portion 15 is provided on the side surface of the vehicle body 12, and the guide rail 14 is disposed in the recessed portion 15. The recessed portion 15 is covered with a cover 16. As shown in FIG. 2, the guide rail 14 has a guide groove 14a including an opening 14b extending in the vehicle front-rear direction and extending in the vehicle front-rear direction on the outer side of the vehicle. When the guide rail 14 is viewed in cross section on a plane orthogonal to the extending direction of the guide groove 14a, it is substantially C-shaped. The guide groove 14a is an internal space formed in the guide rail 14, and communicates with the outside through the opening 14b. And the width | variety of the vehicle up-down direction of the guide groove 14a is the smallest in the site | part which forms the opening 14b.

  As shown in FIG. 2, a curved portion 14 c that curves toward the vehicle interior side is provided on the vehicle front side of the guide rail 14. Therefore, when the door bracket 24 is guided to the curved portion 14c, the slide door 10 is fully closed in a state where it is drawn inside the vehicle body 12 so as to be flush with the side surface of the vehicle body 12 (in FIG. 2). State indicated by a two-dot chain line). Here, since the door bracket 24 is swingable with respect to the slide door 10, the door bracket 24 can follow the guide rail 14 when moving the curved portion 14 c of the guide rail 14.

  Although not shown, the door bracket 24 is also provided in the upper and lower parts (upper part and lower part) of the front end part of the slide door 10 in addition to the part (center part) shown in the figure. Guide rails (not shown) corresponding to the upper and lower portions are also provided at the upper and lower portions of the opening, and the slide door 10 is supported by the vehicle body 12 at a total of three locations. Of course, the sliding door does not necessarily have to be supported at three positions with respect to the vehicle body.

  As shown in FIGS. 3 to 5, the door bracket 24 has a base portion 24 a extending in the vehicle vertical direction. The base 24a has a bifurcated portion 24b that is bifurcated and bent in the vehicle inner direction at the upper end. A pair of guide rollers 24c (rolling elements) having a rotation axis in the vertical direction of the vehicle is rotatably mounted at each end of the bifurcated portion 24b. Below the guide roller 24c, a running roller 24e (rolling element) is rotatably mounted on a shaft portion 24d extending from the base portion 24a toward the vehicle inner side. Since the guide roller 24c and the traveling roller 24e are located in the guide groove 14a and abut against the guide rail 14 so as to be able to roll, the door bracket 24 is movably linked to the guide rail 14. The base 24a has a door link portion 24f bent at the lower end thereof in the vehicle outer direction. As shown in FIG. 2, the sliding door 10 is linked to the front end of the door linking portion 24f so as to be swingable with the vehicle vertical direction as a rotation axis.

  As shown in FIGS. 3 and 5, the door bracket 24 has a tensioner 26 (shown in FIG. 7) that is located outside the guide groove 14 a and directly below each of the rollers 24 c and 24 e and provided at the end 22 </ b> A of the cable 22. It has a cable end support 25 to be engaged. However, only the door bracket 24 driven by the cable 22 (in this embodiment, the door bracket 24 at the center portion) has the cable end support portion 25. Here, “directly (immediately above)” does not necessarily indicate strictly directly (directly above), but has a certain range. As shown in FIG. 3, the width L in the vehicle width direction of the recessed portion 15, that is, the distance from the outer end of the vehicle body 12 to the bottom surface of the recessed portion 15 is included in “directly below (directly above)”. Of course, the structure located right under (right above) each roller 24c, 24e is preferable.

  The cable end support portion 25 is formed by bending and projecting the base portion 24a in the vehicle inner side direction. The cable end support portion 25 has a through hole 25a in which the tensioner 26 can be arranged in parallel in the vehicle width direction in the vehicle front-rear direction. It is the structure which has the base part through-hole 25b. More specifically, as shown in FIG. 4, the base portion 24 a and the door linking portion 24 f are configured from the main body member 30 and the through hole forming member 31 as follows.

  The main body member 30 has a base portion 30a corresponding to the base portion 24a and a door link portion 30b corresponding to the door link portion 24f. A through-hole 30c is formed in a substantially rectangular shape extending in the vehicle front-rear direction at the lower end of the base 30a and in the center in the vehicle front-rear direction.

  The through-hole forming member 31 has a first vertical wall portion 31a extending in the vehicle vertical direction. An upper wall portion 31b extends in the vehicle inner direction from the lower end of the first vertical wall portion 31a, and a second vertical wall portion 31c extends downward from the vehicle inner end portion of the upper wall portion 31b. Further, a lower wall portion 31d extends from the second vertical wall portion 31c in the vehicle outer direction, and a bent portion 31e bent downward from the vehicle outer end portion of the lower wall portion 31d and then bent in the vehicle outer direction. Extend.

  The upper wall portion 31b, the second vertical wall portion 31c, and the lower wall portion 31d of the through hole forming member 31 are fitted in the through hole 30c of the main body member 30. At this time, the first vertical wall portion 31a is in contact with the base portion 30a, and the bent portion 31e is in contact with the door link portion 30b. And the bending part 31e and the door connection part 30b are connected with the volt | bolt 32 shown in FIG. 5, and the main body member 30 and the through-hole formation member 31 are united. As described above, the through hole 25a includes the upper wall portion 31b, the second vertical wall portion 31c, the lower wall portion 31d, and the base portion 30a. The base through hole 25b includes an upper wall portion 31b, a lower wall portion 31d, and a base portion 30a. Here, in the present embodiment, the cable end support portion 25 and the base portion 24a are separate members, but may of course be integrated members. The cable end support portion 25 is provided with a pair of upper and lower engagement holes 25c penetrating in the vehicle vertical direction in the upper wall portion 31b and the lower wall portion 31d, and from the upper wall portion 31b to the second vertical wall portion 31c. And the through-hole 25d penetrated in the vehicle width direction from the lower wall part 31d to the 2nd vertical wall part 31c is provided.

  As shown in FIG. 7, one end 25e1 (or the other end 25e2) of the cable end support 25 is inserted into the end 22A of each cable 22 drawn from the drum of the drive unit 21 through the through hole 25a. A tensioner 26 having a locking claw 26a (engagement site) that engages with the tensioner 26 is provided. Further, the tensioner 26 prevents the slack of each cable 22. Specifically, as shown in FIG. 8, the tensioner 26 has a substantially rectangular parallelepiped-shaped tensioner housing 26c extending in the vehicle front-rear direction. The tensioner housing 26c has insertion holes 26g through which the cables 22a and 22b are inserted, and slidably holds holding shafts 26b that hold the ends of the cables 22a and 22b inserted through the insertion holes 26g. . The tensioner housing 26c stores a coil spring 26d interposed between one end of the tensioner housing 26c and the holding shaft 26b, and the coil spring 26d urges the holding shaft 26b in opposite directions to hold the coil spring 26d. Tension is applied to the open side cable 22b and the close side cable 22a connected to the shaft 26b. Further, the end portion of the holding shaft 26b has a larger diameter than other portions of the holding shaft 26b, and is prevented from coming off by a claw portion 26e that protrudes to the inside of the tensioner housing 26c.

  As shown in FIG. 7, the tensioner housing 26 c has a pair of concave portions 26 f that are concave in the vehicle vertical direction at the center in the vehicle longitudinal direction. A pair of locking claws 26a that are cantilevered and project in the vehicle vertical direction are formed at the tip of the tensioner housing 26c. Therefore, as shown in FIG. 9, when the tensioner 26 is inserted into and penetrates the through hole 25a of the door bracket 24 while elastically deforming both the locking claws 26a from the front of the vehicle, the released both locking claws 26a are elastically restored. Accordingly, it protrudes outward in the vehicle vertical direction from the cable end support portion 25. In this way, both the locking claws 26a are locked to the vehicle rear end 25e1 of the cable end support portion 25 (or the vehicle front end 25e2 when inserted from the vehicle rear), which is opposite to the insertion direction. It is prevented from coming off in the direction. Here, the tension applying direction of the tensioner 26 matches the penetration direction of the through hole 25a, that is, the mounting direction of the tensioner 26.

  As shown in FIG. 10, the restriction member 27 engages the cable end support portion 25 and the tensioner 26 from the outside of the vehicle in a state where the tensioner 26 is inserted into the through-hole 25 a from the opposite direction. The movement of the tensioner 26 in the vehicle front-rear direction relative to the end support portion 25 is restricted. The restricting member 27 has a substantially T-shape when viewed in the vehicle vertical direction. That is, the restricting member 27 includes a fitting portion 27a that fits into the base through hole 25b of the door bracket 24 extending in the vehicle front-rear direction, an end portion in the vehicle vertical direction of the fitting portion 27a, and a center portion in the vehicle front-rear direction. And a bifurcated portion 27b projecting in the vehicle inner direction. The bifurcated portion 27b is formed with a locking claw 27c that is cantilevered and protrudes in the vehicle vertical direction. Further, the width of the forked portion 27b in the vehicle front-rear direction substantially matches the width of the recessed portion 26f, and the forked portion 27b fits into the recessed portion 26f. Here, as shown in FIG. 4, the locking claw 27c engages with the pair of engagement holes 25c described above, and the front end in the vehicle inner side of the bifurcated portion 24b engages with the pair of through holes 25d described above.

<Assembly Method of Each Cable 22 to Door Bracket 24>
As shown in FIG. 9, when one tensioner 26 (for example, the tensioner 26 on the closed cable 22a side) is connected to the cable end support 25, the cable end located outside the guide groove 14a from the rear of the vehicle. The tensioner 26 is locked to the door bracket 24 by being inserted into the through hole 25 a of the support portion 25. Next, when the other tensioner 26 (for example, the tensioner 26 on the open-side cable 22b side) is connected to the cable end support portion 25, tension is applied to the cable 22 so that the sliding door 10 is reliably operated. The tensioner 26 is inserted into the through hole 25a from the front of the vehicle while resisting the tension, and the tensioner 26 is locked to the door bracket 24. At this time, as shown in FIG. 10, the tensioners 26 are arranged in parallel in the vehicle width direction. In this state, the regulating member 27 is inserted into the base through hole 25b from the outside of the vehicle with respect to the cable end support portion 25 and the tensioner 26. In this way, the tensioner 26 and the door bracket 24 are more firmly engaged by the restriction member 27. Of course, the cable 22 may be assembled from either side of the cables 22a and 22b. As a result, the end 22 </ b> A of the cable 22 is connected to the cable end support 26, that is, the door bracket 24.

<Operational effects obtained in this embodiment>
According to this embodiment, the following effects can be obtained.

    (1) Since the cable end support portion 25 is located outside the guide groove 14a, when the cable 22 is assembled to the door bracket 24, it is not necessary to assemble the cable 22 in the guide groove 14a, and the assemblability is improved. Furthermore, since the engaging claw 26a engages with the cable end support portion 25 simply by inserting the tensioner 26 through the through hole 25a, the cable 22 can be easily connected to the cable 22 even when tension is applied to the cable 22 in particular. It can be assembled to the end support 25. In addition, since the tensioner 26 of the cable 22 is supported directly below the rollers 24c and 24e, the trajectory difference between the cable 22 and the guide rail 14 due to the movement of the door bracket 24 is reduced, and the deflection of the cable 22 can be suppressed. In addition, the assembly of the power slide door device 20 can be improved and the operation reliability can be secured.

  (2) Since the tension applying direction of the tensioner 26 and the mounting direction of the tensioner 26 coincide with each other, for example, when the tensioner 26 is pulled in the vehicle front-rear direction when the tensioner 26 is assembled to the cable end support 25, the tensioner resists the tension. Since the cable 22 is pulled out from the housing 26c, the assembly is easy. Further, since the tensioner 26 constitutes a tensioner, there is no need to provide a tensioner inside the drive unit 21, and the drive unit 21 can be made compact and simple.

  (3) The movement of the tensioner 26 in the sliding direction relative to the cable end support portion 25 can be further restricted by the restriction member 27. Therefore, the engagement between the tensioner 26 and the cable end support portion 25 can be further strengthened, and the operation reliability of the power slide door device 20 can be improved. Further, the tensioner 26 can be engaged with the cable end support portion 25 only by inserting the tensioner 26 into the through hole 25a from the opposite directions. Therefore, the cable 22 can be easily assembled to the cable end support portion 25 even when tension is applied to the cable 22 in particular. Further, since the restricting member 27 is engaged from the outside of the vehicle, for example, even when the restricting member 27 is assembled in a state where the slide door 10 is assembled to the door bracket 24, it is easy to assemble.

  (4) Since the restricting member 27 restricts the movement of the tensioner 26 in the sliding direction both upward and downward by the bifurcated portion 27b and restricts the activation of the cable end support portion 25 in the sliding direction by the fitting portion 27b, the structure is simple. Thus, the tensioner 26 and the cable end support 25 can be fixed.

  In addition, this invention is not limited to the said embodiment, You may change into the aspect shown below.

  In the above embodiment, the power slide door device 20 is provided on the guide rail 14 in the center portion, but is not limited thereto, and may be provided on the guide rail 14 in the upper portion and the lower portion.

  In the above embodiment, the tensioners 26 are arranged in parallel in the vehicle width direction, but may be arranged in parallel in the vehicle vertical direction, for example.

  In the above embodiment, if the engaging force between the engaging claw 26a and the cable end support 25 is large enough to withstand when the sliding door 10 is operated, the restricting member 27 is not necessarily required, and the restricting member 27 There may be a configuration without.

  The restriction member 27 is not limited to the shape of the above-described embodiment as long as the restriction member 27 has a shape that restricts the movement of the tensioner 26 with respect to the cable end support portion 25 in the vehicle front-rear direction.

  In the above embodiment, the tensioner 26 having the engagement claw 26 a is connected to the end 22 </ b> A of the cable 22, but a cable end having the engagement claw 26 a may be used without using the tensioner 26. The cable 22 may be provided with the engaging claw 26a directly.
