DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the cable routing support portion structure of the slide door according to the embodiment of the present invention will be described.
[0014]
FIG. 1 is a schematic plan view of the cable routing support portion structure in a state where the slide door SD is closed, and FIG. 2 is a schematic plan view of the cable routing support portion structure in a state where the slide door SD is opened, FIG. 3 is a view showing a state in which the slide door SD is opened and closed, and FIG.
[0015]
This cable routing support structure provides a bending guide for the cable 2 (shown only in FIG. 6) disposed between the vehicle body B and the slide door SD. The first support member 20 and the second support member 30 that respectively support one end and the other end of the cable guide 1 are provided.
[0016]
The cable 2 includes at least one electric wire for feeding power to the slide door SD and one signal transmission / reception wire between the slide door SD and the vehicle body B, and is routed between the vehicle body B and the slide door SD. Is done.
[0017]
The cable guide 1 is constituted by a plurality of link members (piece members) 3 connected in a linear shape, and one end portion thereof is supported on the vehicle body B side by the first support member 20, and the other end portion is provided. It is supported by the slide door SD by a second support member 30 described later. The cable 2 is inserted into each link member 3 of the cable guide 1 so that the cable 2 is bent. In FIG. 3, a position P1 shows a state where the slide door SD is completely closed (fully closed state), and a position P2 shows a state where the slide door SD is partially opened (half open state). P3 shows a state where the slide door SD is completely opened (fully opened state).
[0018]
Here, the first support member 20 is formed of resin or the like, and is fixed to the vehicle body through screws or the like not shown. More specifically, it is fixed to the lower part of the door frame of the vehicle body.
[0019]
The first support member 20 includes a guide tube portion 21 that guides and guides the cable 2 from the vehicle body B, and one end portion of the cable guide 1 is supported by the guide tube portion 21. The cable 2 is led out of the vehicle body B from the vehicle body B side through the guide cylinder portion 21 and is guided through the cable guide 1. The guide tube portion 21 and the link member 3 at one end of the cable guide 1 are connected with the same configuration (described in detail later) as the link members 3 are connected to each other.
[0020]
The guide cylinder portion 21 is directed to the slide door SD side, and the one end portion of the cable guide 1 and the one end portion of the cable 2 are not parallel to the slide movement direction Q of the slide door SD and are connected to the slide door SD. It supports to be directed toward. That is, the guide tube portion 21 is slightly inclined to the rear of the vehicle body B (the direction away from the second support member 30 in the fully closed state), and one end portion of the cable guide 1 and one end portion of the cable 2 are The main body B is supported so as to be oriented slightly obliquely rearward.
[0021]
The second support member 30 is made of resin or the like, and is fixed to the slide door SD via screws or the like not shown. More specifically, it is fixed to the lower part of the slide door SD. This 2nd support member 30 and the other end part of the cable guide 1 are connected by the structure (it explains in full detail later) similar to connecting link member 3 mutually.
[0022]
Further, in the fully closed state of the slide door SD, the second support member 30 is at the vehicle front position of the first support member 20. In this state, the second support member 30 supports the other end portion of the cable guide 1 and the other end portion of the cable 2 so as to be directed toward the first support member 20 along the slide movement direction Q. Yes. Further, when the slide door SD is opened from this state, the second support member 30 moves backward on the side of the first support member 20. Accordingly, in the fully open state of the slide door SD, the second support member 30 separates the other end portion of the cable guide 1 and the other end portion of the cable 2 from the first support member 20 along the slide movement direction Q. It is supported so that it is oriented in the direction to do.
[0023]
Due to the opening / closing structure of the slide door SD, generally, when the slide door SD is fully opened, the slide door SD shifts to the outside of the vehicle body. Accordingly, the distance between the first support member 20 and the second support member 30 in the direction orthogonal to the slide movement direction Q of the slide door SD is larger in the fully opened state than in the fully closed state.
[0024]
As shown in FIGS. 5 to 8, the basic structure of each link member 3 constituting the cable guide 1 is provided with a body 11 and a pair of projections provided at one end of the body 11 and functioning as a rotation shaft. A pair of receiving portions (herein, receiving holes) 15 that pivotally support the convex portion 13 of the link member 3 to be connected to and connected to the other end portion of the body portion 11, the body portion 11, and the body portion 11. A pair of first contact portions 17 provided at one end portion and a pair of second contact portions 19 provided at the other end portion of the body portion 11 are formed of resin or the like.
[0025]
The trunk | drum 11 has a substantially rectangular cylindrical shape, and has the internal diameter which the cable 2 can penetrate. Convex portions 13 are respectively provided on the extending portions 11 a formed by extending portions facing each other (upper and lower side wall portions in FIG. 5) in the opening at one end of the body portion 11. . Receiving portions 15 are respectively provided in extending portions 11b formed by extending portions facing each other (upper and lower side wall portions in FIG. 5) in the opening at the other end of the body portion 11. The convex portion 13 and the receiving portion 15 are provided such that an axis connecting the convex portions 13 on both sides and an axis connecting the receiving portions 15 on both sides are parallel to each other (in the same direction).
[0026]
The width of both extended portions 11b where the receiving portions 15 are provided is set to be slightly wider than the width of both extended portions 11a where the convex portions 13 are provided. For this reason, in the connection part of the link member 3, as shown in FIG. 8, both the convex parts 13 of one link member 3A (refer FIG. 6) are made into the both receiving parts 15 of the other link member 3B (refer FIG. 6). The link members 3A and 3B are connected to each other so as to be fitted from the inside. In such a connected state, the convex portion 13 is rotatably held by the receiving portion 15, whereby the bending angle is variable at the connecting portion between the link members 3 </ b> A and 3 </ b> B.
[0027]
The first and second contact portions 17 and 19 are means for regulating the bending direction R (see FIG. 8) at the connecting portion of the link member 3, and when the two link members 3A and 3B are connected. The two linked members 3A and 3B are in contact with each other in a linearly extending state. And by regulation of these contact parts 17 and 19, in a connection part, one link member 3A is bent only in one bending direction R from the state extended linearly with respect to the other link member 3B. The bending direction R is restricted.
[0028]
That is, when the link members 3 shown in FIGS. 5 to 8 are connected to each other, the link member 3 can be bent only in one direction from the linear state.
[0029]
For example, when the link members 3C and 3D are connected as shown in FIG. 9, the contact portions 17Da and 17Db are linearly connected when the link members 3C and 3D are connected. The contact portions 17Da, 17Db are disposed at positions separated from the contact portion 19C by a predetermined dimension, and the link members 3C, 3D are bent at a predetermined angle in one of the bending directions Ra, Rb. This is realized by enabling contact with 19C.
[0030]
The cable guide 1 includes a first section S1 on the body body B side and a second section S2 on the slide door SD side.
[0031]
The first section S1 is configured to be able to bend in both directions from a substantially straight state, and the bending angle of the connecting portion of each link member 3 is such that the cable guide 1 does not interfere with the member on the vehicle body B side. Range.
[0032]
In the present embodiment, the first section S1 includes a section S1a in which a plurality of link members 3 are connected so as to be bent only in one direction from a straight state, and a plurality of link members 3 can be bent in both directions from a straight state. And a section S1b connected to each other. That is, in the first section S1, not all of the respective connecting portions can be bent in both directions, but can be bent in both directions as viewed in the entire longitudinal direction.
[0033]
The section S1a that can be bent only in one direction is set on the vehicle body B side in the first section S1, and here, one link portion between the link member 3 and the first support member 20 and the link member 3 are provided. A section including two connecting portions between each other is a section S1a that can be bent only in the one direction (see FIG. 4).
[0034]
In addition, the section S1b that can be bent in both directions is set on the second section S2 side (the slide door SD side) in the first section S1, and here, the four connecting portions of the link members 3 are connected to each other. The included section is the section S1b that can be bent in both directions (see FIG. 4).
[0035]
When the other end of the cable guide 1 is pulled rightward in FIGS. 3 and 4 (the sliding door SD is fully closed), the entire first section S1 is rotated clockwise (FIGS. 3 and 4). In the figure). In this case, the bending angle of the connecting portion between the link members 3 in the first section S1 is such that the cable guide 1 does not interfere with the outer body of the slide door SD, and the rail for the slide door SD on the vehicle body B side. The range is set so as not to interfere with the RL.
[0036]
On the other hand, in a state where the other end of the cable guide 1 is pulled leftward in FIGS. 3 and 4 (a fully open state of the slide door SD), there is a section S1a that can be bent only in one direction in the first section S1. The section S1b, which can be bent in both directions, is bent in a counterclockwise direction (on the drawings in FIGS. 3 and 4). In this case, the bending angle of the connecting portion between the link members 3 in the first section S1 is set in a range in which the cable guide 1 does not interfere with the slide door frame rear body Ba on the vehicle body B side. Specifically, in the section S1a that can be bent in only one direction in the first section S1, the bending angle toward the rear of the vehicle is 0 degree, and in the section S1b that can be bent in both directions, the distance between the link members 3 is four. Each of the connecting portions is configured to be bent by 20 degrees. Further, since the first support member 20 supports one end of the cable guide 1 in a posture inclined 10 degrees toward the rear of the vehicle with respect to the direction orthogonal to the slide movement direction Q, 20 degrees × 4 + 10 degrees = 90 degrees. Thus, the second section S2 can extend rearward along the slide movement direction Q.
[0037]
That is, the cable guide 1 is disposed so as to extend toward the second support member 30 by being bent in the first section S <b> 1 while extending away from the vehicle body B side.
[0038]
In particular, in the fully open state, the cable guide 1 extends so as to be separated from the vehicle body B side by the section S1a, and is bent toward the rear of the vehicle body B in the section S1b.
[0039]
In addition, the bending angle and the bending direction of the connecting portion between the link members 3 in the first section S1 are appropriately determined depending on the arrangement position, shape, and the like of various members (the body itself and the rail RL) on the vehicle body B side. Be changed.
[0040]
The second section S2 is configured to be bent only in one direction from the substantially straight state.
[0041]
In the state where the other end portion of the cable guide 1 is pulled rightward in FIGS. 3 and 4 (the sliding door SD is fully closed), the second section S <b> 2 is straight toward the second support member 30. It extends in a shape. On the other hand, in the state where the other end of the cable guide 1 is pulled leftward in FIGS. 3 and 4 (the slide door SD is fully opened), the second section S2 is clockwise (upper view in FIGS. 3 and 4). And is extended toward the second support member 30 while being reversed to a substantially J shape in the horizontal direction.
[0042]
The cable guide 1 is covered with a tube body 40 shown in FIG.
[0043]
The tube body 40 is formed into a bendable cylindrical shape by an elastic material such as rubber or elastic plastic. In this embodiment, it is formed in a bellows tubular shape so that it can be easily bent, but it is not necessarily formed in a bellows tubular shape.
[0044]
The cable routing support portion structure of the slide door SD configured as described above is such that when the slide door SD is fully closed, the entire first section S1 is bent clockwise and the second section S2 is substantially straight. It is in the state extended to the state (first bent form).
[0045]
When the slide door SD is opened from this state, in the first section S1, a section S1a that bends in only one direction extends linearly, and a section S1b that is bent in both directions bends in the opposite direction. Subsequently, since the bending direction is limited to one direction in the second section S2, it is gradually bent from the link member 3 on the first section S1 side toward the link member 3 on the slide door SD side. Therefore, when opening the slide door SD, the bending mode of the cable guide 1 is limited to a predetermined mode.
[0046]
In the fully opened state of the slide door SD, the second section S2 extends toward the second support member 30 while being reversed in a substantially J shape (second bent form).
[0047]
Note that when the slide door SD is closed, it is bent and deformed in the opposite manner to the above.
[0048]
According to the cable routing support structure configured as described above, the cable guide 1 extends toward the second support member 30 after extending away from the vehicle body B side. In the other members, this embodiment, interference with the slide door frame rear body Ba on the vehicle body B side and the rail RL for the slide door SD can be prevented.
[0049]
In particular, the first section S1 includes a section S1a in which a plurality of link members 3 are connected so as to be bent only in one direction from a straight state, and a plurality of link members 3 are connected so as to be able to be bent in both directions from a straight state. Since the configuration includes the section S1b, the mode in which the cable guide 1 is separated from the vehicle body B side can be easily changed between the first bent form and the second bent form.
[0050]
Further, since the second section S2 of the cable guide 1 can be bent only in one direction, interference between the second section S2 and other members can be prevented.
[0051]
Further, since one end of the cable guide 1 is supported by the first support member 20 so as to incline toward the rear of the vehicle, when the slide door SD is opened, the first guide member 20 extends in the longitudinal direction of the second section S2 of the cable guide 1. The acting force is easily converted as a force that smoothly bends the first section S1 and the like in the opposite direction, prevents buckling of the second section S2 and the like, so that the cable guide 1 is removed from the first bent form. It can be smoothly bent and deformed to the second bent form.
[0052]
Moreover, since the cable guide 1 is covered with the bendable tubular tube body 40, the cable 2 can be protected against water and dust. In addition, it is possible to prevent noise caused by rattling between the link members 3.
[0053]

As described above , according to the cable routing support portion structure of the sliding door according to claim 1 of the present invention, the cable guide extends toward the second support member after extending so as to be separated from the vehicle body body side. Interference with other members on the vehicle body side can be prevented.
In particular, according to the first aspect of the present invention, the first section of the cable guide includes a section that can be bent only in one direction from a substantially straight state. It is possible to easily vary the manner in which the cable guide is separated from the vehicle body side.
[0054]
Moreover, according to the cable routing support part structure of the sliding door according to claim 2, since the bending direction in the second section of the cable guide can be limited, interference between the second section and other members can be prevented. .
[0055]
According to the invention of claim 3, when the sliding door is slid, the cable guide is smoothly bent and deformed from the first bent form to the second bent form.
[0056]
Furthermore, according to the invention of claim 4, since the cable guide is set at a bending angle so as not to interfere with the member on the vehicle body side in the first section, the interference to the vehicle body side is prevented. It can be prevented more reliably.
[0058]
