Hereinafter, a mold for a bending regulating member, a bending regulating member, and a power feeding device according to an embodiment of the present invention will be described. First, the curvature regulating member and the power feeding device will be described.

FIG. 1 is a diagram showing a power feeding device to which a bending regulating member according to an embodiment of the present invention is applied. The power feeding device 1 of the present embodiment is electrically connected to the vehicle 5 having the vehicle body 60 and the slide door 50 (slide member) via a wire harness 110 arranged between the vehicle body 60 and the slide door 50. It is a device. In FIG. 1, the right side in the figure corresponds to the front side of the vehicle 5, the left side in the figure corresponds to the rear side of the vehicle 5, the upper side in the figure corresponds to the outside of the vehicle 5, and the lower side in the figure corresponds to the vehicle 5. Corresponds to the inside of. Further, the vertical direction in the figure is the X direction in the present embodiment, the horizontal direction in the figure is the Y direction in the present embodiment, and the vertical direction with respect to the paper surface is the Z direction.

In the power feeding device 1, electric power is supplied from a power source (not shown) provided on the vehicle body 60 to an electric device (not shown) provided on the slide door 50 via a wire harness 110. Further, in the power feeding device 1, an electric signal is exchanged between a control means (not shown) provided on the vehicle body 60 and an electric device (not shown) provided on the slide door 50 via a wire harness 110. The power feeding device 1 includes a wire harness 110, a corrugated tube 120, a bending regulating member 130, a door side holding portion 140, and a vehicle body side holding portion 150.

As shown in FIG. 4 which will be referred to later, the wire harness 110 is formed by bundling a plurality of covered electric wires 111 with tape or the like. In the wire harness 110, a portion of the wire harness 110 between the vehicle body 60 and the slide door 50 is passed through a corrugated tube 120 which is a flexible tube made of a resin material. The bending restricting member 130 is arranged between the inner surface of the corrugated tube 120 and the wire harness 110 so as to surround the wire harness 110 in the circumferential direction and along the wire harness 110. The curvature regulating member 130 will be described in detail later.

One end of the corrugated tube 120 on the slide door 50 side is swayably held by the door side holding portion 140 on the XY plane with the Z direction, which is the vertical direction of the vehicle 5, as the swing axis direction. The door-side holding portion 140 is fixed to the sliding door 50. The door-side swing shaft 141 provided on the door-side holding portion 140 along the Z direction is parallel to the slide door 50 and orthogonal to the opening / closing direction D11 (Y direction, which is the front-rear direction of the vehicle 5) of the slide door 50. It is the axis. One end of the corrugated tube 120 on the sliding door 50 side is swayably held around the door-side swing shaft 141 by the door-side holding portion 140. By holding the corrugated tube 120 by the door-side holding portion 140, a part of the wire harness 110 on the sliding door 50 side is swingably held around the door-side swinging shaft 141 on the XY plane. The slide door 50 side of the wire harness 110 protrudes from one end of the corrugated tube 120 on the slide door 50 side. Further, the wire harness 110 extends to the electric device of the sliding door 50 after exiting the door-side holding portion 140 through a passage (not shown) inside the door-side holding portion 140.

On the other hand, one end of the corrugated tube 120 on the vehicle body side 60 is swayably held by the vehicle body side holding portion 150 on the XY plane with the Z direction, which is the vertical direction of the vehicle 5, as the swing axis direction. The vehicle body side holding portion 150 is fixed to the vehicle body 60. The vehicle body side swing shaft 151 provided on the vehicle body side holding portion 150 along the Z direction is an axis parallel to the slide door 50 and orthogonal to the opening / closing direction D11 of the slide door 50. One end of the corrugated tube 120 on the vehicle body side 60 is swayably held around the vehicle body side swing shaft 151 by the vehicle body side holding portion 150. By holding the corrugated tube 120 by the vehicle body side holding portion 150, a part of the wire harness 110 on the vehicle body side 60 side is oscillatingly held around the vehicle body side swing shaft 151 on the XY plane. The vehicle body 60 side of the wire harness 110 exits from one end of the corrugated tube 120 on the vehicle body 60 side, and further exits from the vehicle body side holding portion 150 through a passage (not shown) inside the vehicle body side holding portion 150. , Extends to a power source and control means (not shown) in the vehicle body 60.

When the slide door 50 is fully closed, the door side holding portion 140 is located on the front side of the vehicle 5 with respect to the vehicle body side holding portion 150, as shown in FIG. Then, the corrugated tube 120, that is, the wire harness 110 inside the corrugated tube 120, extends in a substantially linear state between the vehicle body side holding portion 150 and the door side holding portion 140.

When the slide door 50 is opened in the opening direction D111 toward the rear of the vehicle 5, one end of the corrugated tube 120 on the slide door 50 side swings as follows at the initial stage. That is, one end of the sliding door 50 swings on the XY plane so as to move away from the slide door 50 and toward the front side of the vehicle 5 in the direction opposite to the opening direction D111. The door side holding portion 140 is provided with a coil spring to promote such swinging. This coil spring urges one end of the corrugated tube 120 on the slide door 50 side in an urging direction D12 that separates the corrugated tube 120 from the slide door 50 and directs the slide door 50 in a direction opposite to the opening direction D111.

Due to the above-mentioned swing in the initial stage of opening the slide door 50, the wire harness 110 inside the corrugated tube 120 is next during the subsequent movement of the slide door 50 in the opening direction D111, that is, when the slide door 50 is half-opened. It curves like. That is, as shown in FIG. 1, the wire harness 110 draws a U-shape on the XY plane so as to be convex from the vehicle body side holding portion 150 to the door side holding portion 140 toward the front side of the vehicle 5. It is bent and curved in the allowable direction D13 so as to go to the outside of 60.

In the following, the wire harness 110 inside the corrugated tube 120 may be simply referred to as a wire harness 110 without particular mention.

The U-shaped curvature as described above reduces the burden on the corrugated tube 120 and the wire harness 110 as compared with the case where the wire harness 110 is curved in an S shape on an XY plane, for example.

While the slide door 50 is moving in the opening direction D111, the arm on the slide door 50 side in the U shape of the wire harness 110 moves toward the front side of the vehicle 5 due to the urging of the urging direction D12 by the door side holding portion 140. Is extended in a straight line. At this time, the arm on the vehicle body 60 side is linearly extended toward the front side of the vehicle 5. The U-shape of the wire harness 110 on the XY plane while the slide door 50 is moving is adjusted by the behavior of each of these parts and the function of the curvature regulating member 130 described later.

As the slide door 50 moves in the opening direction D111, the arm of the wire harness 110 on the slide door 50 side in the U shape extends and the arm on the vehicle body 60 side shortens. Then, when the arm on the vehicle body 60 side is shortened to some extent, one end of the wire harness 110 on the vehicle body 60 side swings toward the rear side of the vehicle 5 in the swing direction D15. After that, in this state, the slide door 50 moves in the opening direction D111 and reaches the fully opened state.

When the slide door 50 is closed from this fully open state in the closing direction D112, the wire harness 110 follows an operation opposite to that when the slide door 50 is opened. First, at the initial stage, one end of the wire harness 110 on the vehicle body 60 side swings in the direction opposite to the swing direction D15, so that the wire harness 110 becomes U-shaped on the XY plane. After that, when the slide door 50 continues to move in the closing direction D112 and the arm on the slide door 50 side in the U shape becomes short to some extent, one end of the wire harness 110 on the slide door 50 side swings as follows. .. That is, at this stage, one end of the wire harness 110 on the slide door 50 side opposes the urging by the door side holding portion 140 and moves to the rear side of the vehicle 5 on the side opposite to the urging direction D12. Swing. After that, in this state, the slide door 50 moves in the closing direction D112, and the wire harness 110 reaches the fully closed state while being extended in a straight line state.

Here, the end portion of the vehicle body 60 on the floor on the sliding door 50 side is lowered one step, and is a step 61 in which the passenger puts his / her foot on boarding. When opening and closing the slide door 50, the arm on the vehicle body 60 side of the U-shaped wire harness 110 as described above passes near step 61 on the XY plane.

At this time, in general, in the field of a power feeding device attached to a sliding door of a vehicle, there is a desire to suppress swelling toward the vehicle body when the wire harness bends when the sliding door is opened and closed. Therefore, in the present embodiment, in order to regulate the curvature that causes the wire harness 110 to inflate toward the vehicle body 60 side in this way, a curvature regulating member 130 arranged along the wire harness 110 is provided. The bending restricting member 130 limits the bending of the wire harness 110 on the XY plane. Then, the bending restricting member 130 allows bending in the allowable direction D13 such as bending the wire harness 110 to the outside of the vehicle body 60 on the XY plane. On the other hand, with respect to the regulation direction D16 in which the wire harness 110 is bent inward of the vehicle body 60 on the side opposite to the allowable direction D13, the bending of the predetermined limit state or more is restricted.

FIG. 2 is a diagram showing a bending regulating member shown in FIG. 1, and FIG. 3 shows a detailed structure of the bending regulating member, with a part of the bending regulating member shown in FIG. 2 as a typical example. It is a perspective view shown in. Further, FIG. 4 is a cross-sectional view showing a cross section taken along line V11-V11 in FIG.

The bending restricting member 130 is arranged between the inner surface of the corrugated tube 120 and the wire harness 110 so as to surround the wire harness 110 in the circumferential direction and to guide the bending along the wire harness 110. The curvature regulating member 130 has substantially the same length as the corrugated tube 120. FIG. 2 shows the curvature regulating member 130 curved in a circular shape, with the upper end in the drawing being the vehicle body 60 side and the lower end being the slide door 50 side.

The bending restricting member 130 includes a plurality of member pieces 131 arranged along the wire harness 110, and a connecting portion 132 that connects the plurality of member pieces 131 to each other adjacent to each other. In the present embodiment, the plurality of member pieces 131 and the connecting portion 132 are integrally molded with each other by the resin material. The connecting portion 132 is a flexible member arranged along the wire harness 110 so that the wire harness 110 is located inside the curved shape when the wire harness 110 is curved in this way.

As a typical example is shown in FIG. 3, each of the plurality of member pieces 131 has a pair of facing walls 1311 facing each other so as to sandwich the wire harness 110 between them, and the pair of facing walls 1311. It is provided with a connecting wall 1312 and a connecting wall. The shape of the cross section of each member piece 131 intersecting the length direction D14 of the wire harness 110 is formed by these three walls in a substantially C shape as shown in FIGS. 3 and 4.

The plurality of member pieces 131 are arranged along the wire harness 110 so that the end faces 1311a of the facing wall 1311 in each member piece 131 face each other. In these plurality of member pieces 131, when the connecting wall 1312 connecting the pair of facing walls 1311 is curved inside the curved shape of the wire harness 110, that is, when the connecting wall 1312 is curved in the allowable direction D13 as shown in FIGS. 2 and 3. It is arranged so as to be located inside the curved shape in. Then, the connecting portion 132 connects the connecting walls 1312 of the member pieces 131 adjacent to each other.

In each member piece 131, the space partitioned by the pair of facing walls 1311 and the connecting wall 1312 opens toward the outside of the curved shape, and is a storage groove 1313 in which the wire harness is housed.

The connecting portion 132 is a plate-shaped member as shown in FIGS. 3 and 4, and is formed thin enough to be bent in either the allowable direction D13 in FIG. 2 and the opposite direction. Has been done. Furthermore, in the curvature regulating member 130, the plate-shaped connecting portion 132 is arranged so as to be orthogonal to the XY plane shown in FIG. As a result, the curvature of the curvature regulating member 130 is limited to the XY plane, and as a result, the curvature of the wire harness 110 is also restricted to the XY plane.

Further, the member piece 131a located at the end portion of the bending restricting member 130 on the vehicle body side 60 side is held by the vehicle body side holding portion 150 shown in FIG. 1 together with the end portion of the corrugated tube 120. On the other hand, the opposite end of the bending restricting member 130, that is, the member piece 131b located at the end on the sliding door 50 side is not held by the door side holding portion 140 shown in FIG. As a result, the member piece 131b can be brought into contact with and separated from the door side holding portion 140 according to the bending of the bending regulating member 130. The member piece 131a on the vehicle body 60 side is provided with a flange 131a-1 for holding the member piece 131a on the vehicle body side holding portion 150.

The bending restricting member 130 is limited to bending on the XY plane shown in FIG. 1, and can be bent in the allowable direction D13 on the XY plane. The bending restricting member 130 cannot be bent beyond the limit state described later in the restricting direction D16 toward the inside of the vehicle body 60 on the side opposite to the allowable direction D13.

In the allowable direction D13, as shown in FIG. 3, the connecting portion 132 bends while the plurality of member pieces 131 adjacent to each other at the curved portion are separated from each other on the opposite side of the connecting portion 132. , The bending regulating member 130 can be bent. As a result, the wire harness 110 is allowed to be bent so as to bend in the allowable direction D13.

On the other hand, with respect to the regulation direction D16, the bending restricting member 130 cannot be bent beyond the limit state because the adjacent members of the plurality of member pieces 131 at the bending portion come into contact with each other on the opposite side of the connecting portion 132. It has become. The state in which adjacent objects are in contact with each other at the curved portion is the limit state in the curvature in the regulation direction D16, and the curvature regulation member 130 cannot be curved in the regulation direction D16 beyond this limit state. As a result, the wire harness 110 is restricted from bending so as to bend beyond the limit state of the bending regulating member 130 in the regulating direction D16.

In the present embodiment, the arrangement direction of the plurality of member pieces 131 (that is, the length direction D14 of the wire harness 110) is set to a substantially total length including the middle thereof, except for a part in the vicinity of the vehicle body side holding portion 150 described later. The curvature restricting member 130 is configured as follows. That is, when the bending restricting member 130 is in a substantially linear state over the substantially entire length of the portion, the adjacent member pieces 131 are configured to come into contact with each other on the side opposite to the connecting portion 132. That is, in the present embodiment, the limit state of the regulation direction D16 is set to a substantially linear state for the portion excluding a part in the vicinity of the vehicle body side holding portion 150. As a result, the wire harness 110 maintains a substantially linear shape except for the portion curved in the allowable direction D13.

Here, as shown in FIG. 1, in the present embodiment, in the regulation direction D16, the swing range of the end portion of the wire harness 110 in the vehicle body side holding portion 150 on the XY plane is the following range. It has become. That is, this swing range is a range in which the end portion of the wire harness 110 stops just before the wire harness 110 is directed parallel to the opening / closing direction D11 of the slide door 50. Therefore, in the present embodiment, the curvature regulating member 130 is configured so that the regulation on the curvature of the regulation direction D16 is slightly relaxed so that the portion near the vehicle body side holding portion 150 can be curved to a certain extent in the regulation direction D16. Has been done. As a result, a part of the wire harness 110 near the vehicle body side holding portion 150 is slightly curved in the regulation direction D16, and the portion where the substantially linear shape is maintained as described above is parallel to the opening / closing direction D11 of the slide door 50. It is possible to turn to.

The above-mentioned limit state in the curvature of the curvature regulating member 130 in the regulation direction D16 is adjusted by the spacing of the member pieces 131. That is, the limit state is set to the substantially linear state by setting the interval between the member pieces 131 to be substantially zero when the bending restricting member 130 is in the substantially linear state. Further, by making the distance between the member pieces 131 open even when the member pieces 131 are in a substantially straight line state, the bending restricting member 130 exceeds the substantially straight line state and reaches the limit state where the member pieces 131 come into contact with each other in the regulation direction. It will be possible to bend to D16, and the regulation will be relaxed.

In the present embodiment, such a bending restricting member 130 is molded with a resin material.

FIG. 5 is a schematic view showing a mold for a bending regulating member for forming the bending regulating member shown in FIGS. 1 to 4.

The bending regulating member mold 7 includes an inner mold 71 and a pair of outer molds 72 arranged so as to sandwich the inner mold 71 with each other. The inner mold 71 has an outer surface shape corresponding to the accommodating groove 1313 in the member piece 131. The outer mold 72 is formed with a plurality of recesses 721 having an inner surface shape corresponding to the outer shape of the member piece 131, and when combined with the inner mold 71, the filling space 7a of the resin material corresponding to the member piece 131 is partitioned. .. After the resin material is filled in the filling space 7a and cured, the bending regulating member 130 is formed by removing the bending regulating member mold 7. The inner mold 71 is pulled out in the drawing direction D17 perpendicular to the paper surface of FIG. 5, and the pair of outer molds 72 are removed in the removing direction D18 away from the inner mold 71.

Here, the inner mold 71 has a convex portion that is fitted into each of the plurality of recesses 721 while being in contact with the opening edge portion 721a on the inner mold 71 side on the inner surface of each of the plurality of recesses 721 of the outer mold 72. 711 is provided. The convex portion 711 is formed so as to be fitted into each of the plurality of concave portions 721 only in the vicinity of the opening edge portion 721a in the length direction D14 of the wire harness 110.

Most of the resin material filling space 7a in the bending regulating member mold 7 is a portion for forming a pair of facing walls 1311 of each member piece 131. FIG. 5 schematically shows a portion of the filling space 7a for forming the facing wall 1311. The convex portions 711 of the inner mold 71 are provided at positions corresponding to both end edges of the wire harness 110 in the length direction D14 on each of the facing walls 1311. As a result, a step 1311b is formed on both end edges of the facing wall 1311 in each member piece 131 of the bending regulating member 130 as shown in FIG.

FIG. 6 is a schematic view showing the member pieces shown in FIG. 3 with emphasis on the steps formed on both end edges of the facing wall.

As shown in FIGS. 3 and 6, the step 1311b is formed in the vicinity of both end edges 1311b-1 of each of the pair of facing walls 1311 in the member piece 131. Each step 1311b has a shape in which the vicinity of each end edge 1311b-1 is stepped down from the other portion on the side opposite to the inside of the accommodating groove 1313. The convex portion 711 of the inner mold 71 described above corresponds to a step 1311b in the vicinity of both end edges 1311b-1 of the facing wall 1311.

Here, in the mold 7 for the bending regulating member of the present embodiment shown in FIG. 5, the convex portion 711 of the inner mold 71 is the opening edge on the inner mold side on the inner surface of the concave portion 721 of the outer mold 72.

Here, when the resin material is filled in the filling space 8a of the bending regulating member mold 8 of the comparative example to form the bending regulating member 930 of the comparative example, the filled resin material is the outer mold 82. There is a possibility of invading the boundary between the periphery of the opening in the recess 821 and the surface of the inner mold 81. When the resin material thus infiltrated is cured, the following burrs shown in FIG. 9 are formed on the bending regulating member 930 of the comparative example. The burrs 931c are formed on both end edges 9311b-1 of the wire harness in the length direction D94 on each of the facing walls 9311. Then, the burr 931c is in a state of protruding from each end edge 1311b-1 toward the adjacent member piece 931. Such a burr 931 includes a burr 931c generated in the adjacent member piece 931 and the member piece 931 when the curvature is regulated by the adjacent member pieces 931 coming into contact with each other in the bending restricting member 930 of the comparative example.

A step 1311b is formed in the vicinity of -1. Therefore, the burr 131c rises from the step 1311b. When the burr 131c rises from such a step 1311b, the following effects can be obtained.

FIG. 10 is a schematic view showing the effect obtained by the burr shown in FIG. 7 rising from a step in the vicinity of the edge of each member piece.

When the burr 131c rises from each member piece 131, that is, the step 1311b near the end edge 1311b-1 of the facing wall 1311, the interference between the wire harness 110 and the burr 131c that fits in the accommodating groove 1313 is caused by the step 1311b. It will be suppressed by the depth. As described above, according to the mold 7 for the bending regulating member of the present embodiment, it is possible to suppress the degree of interference between the burr 131c and the wire harness 110 due to the mold molding.
