Description

  The present invention relates to a wire guide device.

  Patent Document 1 discloses an electric wire guide device installed between a vehicle body and a slide door. The wire guide device includes an elongated wire guide body, a body side bracket for connecting the body side end of the wire guide body to the body, and a slide door side end of the wire guide body for connecting to the slide door. The door side bracket is provided. A wire harness for supplying power to electrical components and the like installed in the slide door is inserted through the wire guide body and both brackets. The wire guide body is configured by connecting a plurality of link members so as to be relatively rotatable by a shaft portion. The wire guide body is displaced in the front-rear direction while being curved and deformed on a horizontal plane in conjunction with the opening / closing operation of the slide door.

  Moreover, the body side bracket is arrange | positioned at the rear part of the step part of the entrance / exit opened and closed by a slide door. Therefore, there is a concern that the wire guide body may be stepped on and broken by the passenger. Therefore, in the thing of patent document 1, in order to prevent damaging when an electric wire guide body is stepped on, the following damage prevention means are provided. An insertion portion is formed inside the body-side bracket, and a body-side end link member located at the end on the most body side among the link members constituting the wire guide body is inserted into the insertion port. On the upper wall of the insertion port, a doubly supported beam-like release wall is formed so as to be able to bend outward, and a positioning projection is formed on the inner surface (lower surface) of the upper wall. On the other hand, a positioning recess is formed on the upper surface of the body side end link member. The body-side end link member is held in a disengagement restricted state with respect to the body-side bracket by fitting the positioning protrusion and the positioning recess.

  According to this damage prevention means, when the electric wire guide body is stepped on, the body side end link member assumes an oblique posture and elastically bends the release wall upward. Then, since the positioning protrusion is dissociated from the positioning recess, the body side end link member is detached from the body side bracket. If the body-side end link member is detached from the body-side bracket, a situation in which the wire guide body is broken in the middle or deformed can be avoided.

Japanese Patent Laying-Open No. 2015-024802

  In the above damage prevention means, the body side end link member is inserted into the insertion port of the body side bracket in a non-rotatable state. Therefore, among the plurality of shaft portions that function as the rotation center of the link member of the wire guide body, the shaft portion positioned closest to the body side is positioned closer to the slide door than the body side bracket in the vehicle body width direction. . The arrangement of the shaft means that the allowable range of movement of the wire guide body between the body and the door is narrowed in the vehicle body width direction. Since the wire guide body is displaced in the front-rear direction while being curved and deformed, the narrowness of the movable allowable range is a great restriction in designing the wire guide body.

  This invention is completed based on the above situations, Comprising: It aims at improving the design freedom of an electric wire guide body.

The wire guide device of the present invention is
A plurality of link members are rotatably connected to each other, and in a state where an electric wire routed between the vehicle body and the slide door is inserted therein, while bending and deforming as the slide door opens and closes, A wire guide body that is displaced in the longitudinal direction of the vehicle body;
A bracket that is attached to at least one of the vehicle body and the sliding door, and that connects a terminal portion of the wire guide body to the vehicle body or the sliding door;
A fixing member that constitutes the bracket, has an accommodating space that opens in a vehicle body width direction, and is fixed to the vehicle body or the sliding door;
A rotation member attached to the fixed member so as to be capable of rotating in the front-rear direction of the vehicle body with a rotation support portion formed inside the housing space as a fulcrum, constituting the bracket;
A flexible member that is formed in the rotating member so as to be elastically bent in the vertical direction of the vehicle body, and that rotatably connects the distal end portion of the terminal link member located at the end of the plurality of link members. Having a sex connection part,
The terminal link member is characterized in that the connection with the terminal link member is released while the flexible connection portion is elastically bent as the terminal link member is inclined.

  If the passenger steps on the wire guide body by mistake while the slide door is open, the terminal link member is inclined and comes off the bracket, so that the wire guide body can be prevented from being damaged. In addition, the terminal link member located at the end of the wire guide body is not fixed, but is connected to a rotating member that can rotate in the front-rear direction, so that the entire terminal link member is rotated. As the moving member rotates, it is displaced so as to slide in the front-rear direction. Therefore, compared with the case where a terminal link member does not displace back and forth, the full length of an electric wire guide body can be shortened, or the number of link members can be decreased. Thereby, the restrictions in designing the wire guide body are relaxed, and the degree of freedom in design is improved. Moreover, since it is not necessary to form a means for detaching the terminal link member in the bracket, the bracket can be reduced in size and shape can be simplified.

The rotation support portion 25 includes an upper arc-shaped bearing portion 26 that constitutes a part of the lower end edge of the wire lead-out portion 24, and a lower arc shape that is disposed concentrically with the upper arc-shaped bearing portion 26 below the upper arc-shaped bearing portion 26. It comprises a bearing portion 27 and a pair of front and rear arc-shaped bearing walls 28 concentric with the upper and lower arc-shaped bearing portions 26 and 27. Both the upper and lower arc-shaped bearing portions 26 and 27 are arranged closer to the opening of the accommodation space 22 than the arc-shaped bearing wall 28. The fixing member 21 is formed with a rotation support portion 25 for supporting the rotation member 30, but means for directly contacting or fitting with the body side terminal link member 11B described later is provided. Not formed.

  As shown in FIG. 5, the rotating member 30 is a single part provided with a cylindrical portion 31 whose axis is directed in the vertical direction and a rectangular tube portion 32 that protrudes in the horizontal direction from the outer periphery of the cylindrical portion 31. is there. The rotation member 30 is assembled to the fixed member 21 by fitting the cylindrical portion 31 to the rotation support portion 25. In the state where the rotating member 30 is assembled, most of the region excluding the protruding end portion of the rectangular tube portion 32 is accommodated in the accommodating space 22. The rotating member 30 is supported with respect to the fixing member 21 so as to be able to rotate (swing) in a swinging manner in the horizontal direction (front-rear direction) about the axis of the cylindrical portion 31.

  As shown in FIG. 4, the opening at the upper end of the cylindrical portion 31 communicates with the lower end of the wire lead-out portion 24. The lower end of the cylindrical portion 31 is closed by the bottom wall portion 33. As shown in FIGS. 5 to 7, the rectangular tube portion 32 includes an upper wall portion 34, a lower wall portion 35, and left and right side wall portions 36.

The wire harness H is routed in a state where the wire harness H is bent in a substantially L-shaped routing path constituted by the rectangular tube portion 32, the cylindrical portion 31, and the wire lead-out portion 24.

  The protruding end portion of the upper wall portion 34 protrudes outside the accommodation space 22 (fixing member 21). A slit having a substantially U shape in plan view is formed at the protruding end portion of the upper wall portion 34, and a region surrounded by the slit in the upper wall portion 34 is a flexible connecting portion 38. The flexible connecting portion 38 is formed on an arm portion 39 that extends in a cantilevered manner outward in the radial direction around the rotation axis of the rotation member 30, and an extended end portion of the arm portion 39. The projection 40 is formed. The protrusion 40 has a shape protruding upward from the upper surface (outer surface) of the arm portion 39.

  Similarly to the protruding end portion of the upper wall portion 34, the protruding end portion of the lower wall portion 35 also protrudes to the outside of the accommodation space 22 (fixing member 21). In addition, a slit having a substantially U shape in a bottom view is formed in the protruding end portion of the lower wall portion 35, similarly to the upper wall portion 34. A region surrounded by the slit in the lower wall portion 35 is a flexible connecting portion 38. The flexible connecting portion 38 extends in a cantilever shape outward in the radial direction around the rotation axis of the rotation member 30 (that is, in the same direction as the arm portion 39 on the upper wall portion 34 side). Arm portion 39 and a projection 40 formed on the extended end portion of the arm portion 39.

  A region surrounding the slit and the flexible connecting portion 38 in the protruding end portion of the upper wall portion 34 is a horizontal support plate portion 41. In the upper wall portion 34, the upper surface of the support plate portion 41 and the upper surface of the arm portion 39 are substantially the same height. Accordingly, the protrusion 40 of the upper wall portion 34 protrudes upward from the upper surface of the support plate portion 41. On the other hand, a region surrounding the slit and the flexible coupling portion 38 in the protruding end portion of the lower wall portion 35 is also a horizontal support plate portion 41. In the lower wall portion 35, the lower surface of the support plate portion 41 and the lower surface of the arm portion 39 have substantially the same height. Therefore, the protrusion 40 of the lower wall portion 35 protrudes downward from the lower surface of the support plate portion 41.

  Both the shape of the projection 40 of the upper wall portion 34 in plan view and the shape of the bottom surface of the projection 40 of the lower wall portion 35 are non-circular in which both ends of a pair of parallel straight lines 40S are connected by a pair of arcs 40R. Shape. The radius of curvature of the pair of arcs 40 </ b> R is the same as or slightly smaller than the radius of the inner peripheral surface of the connection hole 15. The pair of straight lines 40 </ b> S are parallel to the extending direction of the arm portion 39. Further, the pair of straight lines 40 </ b> S overlaps both side edges of the arm portion 39 in a plan view and a bottom view.

  The body-side terminal link member 11 </ b> B is connected to the turning member 30 so as to be able to turn substantially parallel about an axis in the vertical direction parallel to the turning center of the turning member 30. Specifically, both the upper and lower connection holes 15 of the body side terminal link member 11B are fitted to the upper and lower protrusions 40 of the rotation member 30, and the body side terminal link member 11B is connected to the rotation member 30 with a connection hole. 15 and the projection 40 can be relatively rotated in the front-rear direction. When the body-side terminal link member 11B rotates with respect to the rotating member 30, the upper plate portion of the body-side terminal link member 11B is placed on the upper surface of the support plate portion 41 of the upper wall portion 34 and the upper surface of the arm portion 39. 12 is in sliding contact, and the lower plate portion 13 of the body side terminal link member 11B is in sliding contact with the lower surface of the support plate portion 41 of the lower wall portion 35 and the lower surface of the arm portion 39.

<Operation and Effect of Example 1>
As shown in FIG. 1, when the slide door S is opened and closed, the rotating member 30 rotates (swings) so that the head swings forward or backward with the rotation support portion 25 of the fixing member 21 as a fulcrum. The guide body 10 is displaced forward or backward while being curved and deformed in a narrow region between the body side bracket 20 and the door side bracket 50. Further, the entire body side terminal link member 11 </ b> B is displaced so as to slide in the front-rear direction with respect to the vehicle body B, and is rotated so as to swing the head relative to the rotating member 30.

  Now, the body side bracket 20 is arrange | positioned in the vicinity of the step of the entrance / exit E opened and closed by the slide door S. As shown in FIG. Therefore, there is a concern that the electric wire guide body 10 may be stepped on by the passenger during the opening / closing operation of the slide door S and broken. However, the body side bracket 20 is not damaged even if the wire guide body 10 is stepped on.

  When the electric wire guide body 10 is stepped on, as shown in FIG. 8, the body-side terminal link member 11 </ b> B tilts obliquely downward with the end portion of the lower plate portion 13 on the connection hole 15 side as a substantially fulcrum. Then, the upper plate portion 12 of the body side terminal link member 11B pushes down the upper support plate portion 41 of the rotating member 30 to be elastically deformed, and the hole edge portion of the upper connection hole 15 interferes with the protrusion 40. Thus, the flexible connecting portion 38 is elastically deformed downward.

  When the flexible connecting portion 38 is further elastically deformed downward, the upper protrusion 40 is detached from the connecting hole 15, and the upper plate portion 12 is further removed from the support plate portion 41, so that the lower connecting hole 15 and the protrusion 40 are separated from each other. The lock is also released. Thus, the body-side terminal link member 11B is detached from the rotating member 30. If the body-side terminal link member 11B is detached from the rotating member 30, a situation in which the wire guide body 10 is broken or deformed is avoided in advance.

  The wire guide device G according to the first embodiment includes a wire guide body 10, a body side bracket 20, and a door side bracket 50. The electric wire guide body 10 is configured by connecting a plurality of link members 11B, 11M, and 11S so as to be rotatable. A wire harness H (electric wire W) routed between the vehicle body B and the slide door S is inserted into the electric wire guide body 10. The wire guide body 10 is displaced in the front-rear direction of the vehicle body B while being curved and deformed as the slide door S is opened and closed. The body side bracket 20 is attached to the vehicle body B, and connects the terminal portion of the wire guide body 10 to the vehicle body B. The door-side bracket 50 is attached to the slide door S and connects the terminal portion of the wire guide body 10 to the slide door S.

  The body side bracket 20 is configured by assembling a fixing member 21 and a rotating member 30. The fixing member 21 has an accommodation space 22 that opens in the vehicle body width direction, and is fixed to the vehicle body B. The rotation member 30 is attached to the fixed member 21 so as to be able to rotate in the front-rear direction with a rotation support portion 25 formed inside the accommodation space 22 as a fulcrum. A flexible connecting portion 38 is formed on the rotating member 30 so that the vehicle body B can be elastically bent in the vertical direction. The flexible connecting portion 38 is rotatably connected to the distal end portion of the body-side terminal link member 11B located at the end of the plurality of link members 11B, 11M, and 11S.

  In the wire guide device G configured as described above, when the wire guide body 10 is stepped on by the passenger and the body-side terminal link member 11B is inclined, the body-side terminal link member 11B is elastically bent while the flexible connecting portion 38 is elastically bent. The connection with is released. Therefore, even if the electric wire guide body 10 is stepped on by a passenger, there is no possibility of damage.

  Moreover, the body side terminal link member 11B located in the most edge part of the electric wire guide body 10 is not fixed, but is connected with the rotation member 30 which can be rotated in the front-back direction. Thereby, the whole body side terminal link member 11B displaces so that it may slide to the front-back direction with rotation of the rotation member 30. FIG. Therefore, compared with the case where the whole body side terminal link member 11B is not displaced back and forth, the wire guide body 10 of the first embodiment shortens the total length of the wire guide body 10 or reduces the number of intermediate link members 11M. You can do it. Thereby, the restrictions on designing the wire guide body 10 are relaxed, and the degree of freedom in design is improved.

  The body side bracket 20 is composed of two members, a fixing member 21 and a rotating member 30, and the fixing member 21 rotates the rotating member 30 so as to swing its head in the front-rear direction of the vehicle body B. Means for supporting is formed. However, the fixing member 21 is not formed with a means for detaching the body side terminal link member 11B from the body side bracket 20. Therefore, since the body side terminal link member 11B is not formed, the fixing member 21 is reduced in size, and the shape and structure of the fixing member 21 are simplified.

  In addition, the flexible connecting portion 38 includes an arm portion 39 that extends in a cantilever manner and a protrusion 40 that protrudes upward or downward from the vehicle body B from the extended end portion of the arm portion 39. Configured. On the other hand, a connecting hole 15 that is rotatably fitted to the protrusion 40 is formed at the tip of the body-side terminal link member 11B. According to this configuration, when the body-side terminal link member 11B is in an oblique posture, the arm portion 39 is elastically bent, so that the fitting between the protrusion 40 and the connection hole 15 is released.

  In addition, the planar view shape of the connecting hole 15 is circular, whereas the planar view shape of the protrusion 40 is a shape in which a pair of parallel straight lines 40S are connected by a pair of arcs 40R, and the pair of arcs 40R are connected. The inner surface of the hole 15 is in sliding contact. According to this configuration, since the contact area between the outer peripheral surface of the protrusion 40 and the inner peripheral surface of the connection hole 15 is smaller than when the protrusion 40 is circular, the rotating member 30 and the body-side terminal link member 11B. The resistance when rotating between the two is reduced.

  Further, the rotating member 30 is formed with a substantially horizontal support plate portion 41 arranged so as to surround the arm portion 39 and slidingly contact the body side terminal link member 11B. According to this configuration, when the electric wire guide body 10 operates normally without being stepped on, the body-side terminal link member 11B is brought into a posture by sliding the body-side terminal link member 11B against the support plate portion 41. Stabilize. That is, the posture of the body side terminal link member 11B is not likely to be inclined. Therefore, the fitting state between the protrusion 40 and the connecting hole 15 is stabilized.
