Description

  The present invention relates to a cable guide device, and more particularly, when a cable spanned between a sliding door of a vehicle and a vehicle body changes in angle in a vertical direction, a horizontal direction, and an oblique direction according to opening and closing operations of the sliding door. The cable is guided so that it can be followed.

Electrical components such as power windows and door locks are mounted on the doors of automobiles, and cables (door harnesses) for constantly supplying power are connected to these electrical components, and these cables are routed to the vehicle body side. It is connected to the power supply side cable on the vehicle body side.
When the door is a sliding door, there is a sliding door that moves in a vertical direction and a horizontal direction orthogonal to the sliding direction when the sliding door is opened and closed. Therefore, the angle of the cable routed between the slide door and the vehicle body in the left-right direction and the up-down direction is also changed.
The cable spanned from the sliding door side to the vehicle body side is fixedly supported on the vehicle body side, but it is necessary to provide a mechanism that can follow the angle change of the cable in the vertical direction, the horizontal direction, and the diagonal direction in the support portion. .

As this type of cable support device, Japanese Patent Laid-Open No. 2004-40862 (Patent Document 1) proposes a device shown in FIG. In this device, a cable spanned between a vehicle body and a sliding door is covered with a cable guide 2 to which a plurality of link members 1 are connected, and one end of the cable guide 2 is connected to a support member 3 fixed to the vehicle body. The cable inserted through the cable guide 2 is routed through the inside of the support member 3.
The support member 3 and the link member 1a at the end of the cable guide 2 are pivotally connected by a horizontal connecting pin P1 to connect the link member 1 to the support member 3 so as to be swingable in the vertical direction. It follows the change in direction angle. On the other hand, the link members 1 adjacent to each other in the cable guide 2 are axially attached by a connecting pin P2 in the vertical direction, are connected so as to be rotatable in the left-right direction, and can follow the angle change in the left-right direction of the cable.
That is, by making the axial direction of the pin P2 connecting the link members 1 of the cable guide 2 and the axial direction of the pin P1 connecting the link member 1 and the support member 3 at the distal end of the cable guide perpendicular to each other. The mechanism can follow the angle change between the vertical direction and the horizontal direction of the cable.

  In the cable support device of Patent Document 1, the amount of vertical displacement is restricted to a vertical angle range in which the link member 1a at the tip of the cable guide 2 can rotate with the pin P1 as a fulcrum, and the link members 1 of the cable guide 2 The amount of displacement in the left-right direction is restricted to the left-right angle range that can be rotated with the pin P2 as a fulcrum. Furthermore, even when it inclines in the diagonal direction, the structure of patent document 1 cannot respond.

The sliding angle of an automobile differs in the amount of angle change in the vertical direction for each vehicle type. Further, the sliding door is configured to be inclined obliquely with respect to the vertical direction as the sliding door is slid from the closed state to the open state. Furthermore, the mounting position and mounting angle of the cable support device to the vehicle are also different.
When the vertical rotation angle range is defined as in Patent Document 1, it takes time to examine the mounting position and mounting angle of the cable support device for each vehicle type. However, when the amount of vertical displacement of the cable is large, When the inclination angle is large, the cable itself is twisted in the structure of Patent Document 1, but there are cases where the cable itself cannot be absorbed only by twisting.

  Further, in Patent Document 1, the link member 1a at the tip of the cable guide 2 is connected to the cable support member 3 so as to be swingable in the vertical direction, and sequentially connected in the front-rear direction to the link member 1a swinging up and down. The link members 1 are connected to each other so as to be able to swing left and right. That is, the cable passing through the link member 1a at the tip is swung in the vertical direction, but cannot be swung in the left-right direction, and the swivel in the left-right direction starts from the next link member 1 connected to the link member 1a. Become. Therefore, the left and right swinging cannot be performed at a position close to the cable support member 3, and the cable is twisted in the link member.

JP 2004-40862 A

  The present invention is intended to solve the problem of Patent Document 1, and can cope with the amount of angular displacement in the vertical and horizontal directions of the cable, and can also cope with the angle change in the oblique direction of the cable. Therefore, an object of the present invention is to provide a cable guide device that can sufficiently cope with a change in the angle of the cable even if the attachment position and the attachment angle to the vehicle are slightly different.

In order to solve the above problems, the present invention is a guide device for a cable routed between a vehicle body and a movable member movably connected to the vehicle body,
An inner guide member and an outer guide member each having a three-dimensional arcuate portion are provided. The inner guide member and the outer guide member are rotatably fitted, and either the inner guide member or the outer guide member. A cable insertion port on the other side, a cable outlet on the other side,
A convex portion for restricting the rotation angle protrudes from either one of the arc surfaces facing the inner and outer directions of the inner guide material and the outer guide material, and the other is loosely fitted with a gap between the entire circumference of the convex portion. Providing a recess made of a groove or a through hole,
The configuration is such that the change in angle in the vertical, horizontal, and diagonal directions of the cable through which the inner guide material and the outer guide material to be fitted are inserted is regulated by contact between the convex portion and the concave portion of the inner guide material and the outer guide material. A cable guide device is provided.

As described above, the cable can be inserted into the inner guide member and the outer guide member that are rotatably connected as described above, so that the angle of the cable can be changed in any of the vertical direction, the horizontal direction, and the diagonal direction. Yes.
Therefore, only within the predetermined angle range in the vertical direction between the support member and the link member at the tip as disclosed in Patent Document 1, and converted within the predetermined angle range in the left-right direction by connecting the link members. Compared with a support device that can be rotated, it can also be rotated in an oblique direction, can be applied to a vehicle type having a different inclination angle, and is excellent in versatility.
In particular, in the present invention, the rotation of the inner guide material or / and the outer guide material in the left / right / up / down / diagonal directions is regulated by bringing the convex portions and the concave portions of the inner guide material and the outer guide material into contact with each other. By adjusting the gap interval between the convex part and the concave part, it is possible to control the rotation angle in the vertical, horizontal, and diagonal directions.
For example, the angular displacement can be set in a wide range by increasing the gap, and can be applied to different vehicle types that differ in the direction in which the angular displacement is displaced. On the other hand, the rotation angle can be restricted to a predetermined angle range by reducing the gap to a set value, and the cable can be prevented from being damaged by excessive bending or twisting.

In Patent Document 1, only the vertical angle change is performed between the support member and the link member at the tip, and the horizontal angle is not changed. Therefore, the cable is twisted at this portion and the cable is twisted. However, in the guide device of the present invention, the angle can be changed simultaneously in the vertical direction, the horizontal direction, and further in the oblique direction, thereby preventing the cable from being twisted and protecting the cable. be able to.
Furthermore, since the guide device of the present invention can deal with a wide range of angle changes in the vertical direction, the left-right direction, and the diagonal direction, when the guide device is attached to a vehicle body or the like, the attachment position and the attachment angle to the vehicle body or the like Therefore, it is not necessary to carry out a detailed examination, and the assembling property at the time of manufacture can be improved.

The arc portions of the inner guide member and the outer guide member are respectively provided in substantially hemispherical shell portions,
The grooves or through holes of the recesses provided in these substantially hemispherical shells are circular in cross section, while the protrusions are cylinders or columns having a smaller diameter than the recesses.

According to the said structure, since the substantially hemispherical shell parts of an inner side guide material and an outer side guide material are connected rotatably, a guide material can be made to follow smoothly also with respect to the angle change of all the directions of a cable. .
Note that the hemisphere of the hemispherical shell portion is not a complete half-split hemispherical shell shape obtained by dividing the spherical shell into two equal parts, but is provided on the outer guide material on one of the convex or concave portions provided on the inner guide material. The shape which can be externally fitted so that the other of the raised convex part or the recessed part can be loosely fitted. Therefore, it is preferable that the outer guide member has a larger diameter than the inner guide member and the opening-side maximum diameter portion slightly protrudes with respect to the hemispherical shell portion of the inner guide member.

Further, when the concave portion provided in the inner guide material or the outer guide material has a circular cross section and the convex portion is a cylinder or a column, the circular arc surfaces are brought into contact with each other, and can be smoothly slid. Therefore, the inner guide member and / or the outer guide member can smoothly follow the change in the angle of the cable.
In addition, the said recessed part and convex part may be a cross-sectional perfect circle shape, and are good also as a cross-sectional oval shape or an ellipse shape. Furthermore, the shape is not limited as long as the shapes are slidable in the three-dimensional direction.

Two to four loose fitting parts for the rotation angle regulating convex part and concave part are provided, and when there are two loose fitting parts, they are arranged at an interval of approximately 90 degrees, and there are three or four loose fitting parts. In this case, it is preferable that they are arranged at equal intervals in the circumferential direction.
According to the said structure, the rotation angle which can follow an inner side guide material or / and an outer side guide material can be controlled with respect to the angle change to the direction of a cable with a convex part and a recessed part.
Further, when four convex portions and four concave portions are provided, the fitting force between the inner guide member and the outer guide member can be increased, and the inner guide member can be prevented from coming off from the outer guide member.

The outer guide member is composed of a split member or an integral member that can be opened and closed via a thin hinge portion, and the outer guide member is fitted on the inner guide member to lock and connect the split member or the integral member opening / closing portion. It is preferable.
According to the above configuration, the inner guide material and the outer guide material can be easily connected without forcibly pushing the hemispherical shell portion of the inner guide material into the hemispherical shell portion of the outer guide material.

When the cable guide device composed of the inner guide member and the outer guide member having the above-described configuration is attached to a support device fixed to a movable member such as a vehicle body or / and a door, either the inner guide member or the outer guide member is attached. While being integrated with the support member attached to the vehicle body or / and the movable member, the cable is inserted into the support member and pulled out to the outside,
The other of the inner guide member and the outer guide member connects a plurality of link members sequentially in a rotatable manner in the same direction, and is connected to the end link member of the chain member sheathed on the cable in the same direction as the other link members. It is connected so that it can rotate.

According to the above configuration, when a chain material in which link members are connected in a chain shape is used as an exterior material for a cable spanned between the vehicle body and the movable member, the inner guide material and the outer guide material on the support material side. By the relative rotation, it is possible to change the angle in a direction that cannot be displaced by the chain material. That is, when the link members of the chain member are rotatable only in the left-right direction, the inner guide member and the outer guide member can rotate in the vertical direction and in the oblique direction.
Therefore, unlike Patent Document 1, there is no need to interpose a link member that can swing up and down between the chain member and the support member. As a result, all the link members of the chain material have the same shape and may be connected so as to swing freely.

The cable guide device of the present invention may be interposed in the middle of the chain member without being attached to the support member attached to the vehicle body or the movable member.
In that case, a plurality of link members are sequentially connected so as to be rotatable in the same direction, and the inner guide member and the outer guide member are interposed between adjacent link members of a part of the chain member sheathed on the cable. The inner guide member and the outer guide member are connected to the link member so as to be rotatable in the same direction as described above.
As described above, when the guide function in the up / down, left / right, and diagonal directions is given to the chain material itself that sheathes the cable routed between the vehicle body and the movable member, the cable bend is applied to the cable support device attached to the vehicle body and the movable member side. It is no longer necessary to have a function to follow.

The cable guide device of the present invention having the above-described configuration can be optimally configured as a guide device for a cable routed between the vehicle body and the sliding door, and supports the guide member so as to be rotatably held. By fixing the material to the vehicle body and / or the door, it is possible to follow the change in the angle of the cable according to the opening / closing operation of the sliding door by the rotation of the guide material.
The cable may be a flat cable in which conductive materials are arranged in parallel and laminated with an insulating resin sheet, or a covered round electric wire.

As described above, according to the present invention, since the cable is inserted into the hollow portion of the inner guide member and the outer guide member that are rotatably connected in the vertical, horizontal, and diagonal directions, the cable is vertically and horizontally Even if the angle is changed in both the direction and the oblique direction, the inner guide member and / or the outer guide member can be rotated to follow, and an overload such as a twist is not generated in the cable.
In addition, it is possible to cope with the amount of displacement in the vertical direction and the horizontal direction with only the guide device, and it is also possible to cope with an angle change in the oblique direction of the cable.
Furthermore, since the rotation of the inner guide member and the outer guide member in the up / down / left / right / oblique directions is regulated by the contact between the convex portions and the concave portions of the inner guide member and the outer guide member, the gap between the convex portion and the concave portion is prevented. By defining, the rotation angle of the inner guide material and / or the outer guide material in the vertical, horizontal, and diagonal directions can be regulated.

Moreover, the cable guide device of the present invention can be provided integrally with a support device attached to a movable member such as a vehicle body and / or a door, and the support device can be provided with a function of following the bending of the cable.
Alternatively, instead of the support device, it is possible to follow the bending of the cable by interposing it in the middle of the exterior material that spans between the vehicle body and the movable member.

The side 20 is connected to the chain member 13 and assembled, and a cable 20 in which a plurality of wires arranged between the sliding door and the vehicle body are bundled is inserted into the chain member 13, the guide device 10, and the support device 5. .
That is, the cable 20 inserted into the hollow portions S4, S2, and S1 of the chain member 13, the inner guide member 12, and the outer guide member 11 is bent by 90 degrees, and the second support member 15 is formed from the second opening 11f of the outer guide member 11. The cable 20 drawn from the upper end of the cylindrical portion 15c is passed through the hollow portion S3 of the cylindrical portion 15c, and is fixed to the fixing piece 15h by tape T.

  The cable 20 on the side pulled out from the cylindrical portion 15 c of the second support member 15 of the support device 5 is routed on the vehicle body side and connected to a floor harness (not shown) and connected to the connector, while being connected to the exterior of the chain member 13. The cable 20 is routed so as to span between the vehicle body and the sliding door, and is connected to a door harness (not shown) and a connector. Thereby, the floor harness and the door harness are electrically connected via the cable 20.

  With the above structure, the chain member 13 can be bent only in the left-right direction, but the inner guide member 12 having a three-dimensional arcuate surface rotates in the vertical, left-right, and diagonal directions with respect to the outer guide member 11. When the cable 20 inserted into the inner guide member 12 changes in angle in the up / down, left / right, and diagonal directions, the inner guide member 12 rotates to follow the angle change, and the change in the angle of the cable 20 changes. Performed smoothly.

For example, when the slide door changes in the left-right direction and the cable 20 also moves in the left-right direction, the spherical held portion 12a of the inner guide member 12 rotates in the left-right direction within the holding portion 11c of the outer guide member 11. As a result, the angle in the left-right direction changes in a larger range as compared with the angular displacement in the left-right direction only by the chain member 13, and follows the change in the left-right direction of the cable 20. Further, as shown in FIG. 6, when the held portion 12a of the inner guide member 12 rotates within the holding portion 11c of the outer guide member 11, the outer peripheral surface of the convex portion 12f provided on the side portion of the held portion 12a is held. The rotation angle of the inner guide member 12 is regulated by interfering with the inner peripheral surface of the recess 11e provided on the inner surface of the portion 11c. This prevents the cable 20 from being greatly bent and damaged.
When the cable 20 is displaced in the left-right direction, the outer guide member 11 also rotates in the left-right direction with respect to the support members 14, 15 and follows the cable 20. The rotation angle in the left-right direction of the outer guide member 11 is restricted to a required angle when the outer guide member 11 interferes with the inclined surface 15 i provided on the second support member 15.

  Further, when the sliding door changes in the vertical direction and the cable 20 is also displaced in the vertical direction, the spherical held portion 12a of the inner guide member 12 rotates in the vertical direction within the holding portion 11c of the outer guide member 11. As a result, a change in the angle in the vertical direction, which was impossible with the chain member 13, occurs to follow the vertical displacement of the cable 20. Also at this time, as described above, the outer peripheral surfaces of the convex portions 12f provided at the upper and lower ends of the held portion 12a interfere with the inner peripheral surfaces of the concave portions 11e provided on the inner surface of the holding portion 11c, and the rotation angle of the inner guide member 12 Is regulated.

  Further, when the sliding door is inclined when sliding and the inclination angle of the cable 20 is also displaced, the spherical held portion 12a of the inner guide member 12 is circumferentially moved around the axis in the holding portion 11c of the outer guide member 11. , The angle of the chain member 13 changes and follows the angular displacement of the cable 20 in the oblique direction.
