  Hereinafter, an embodiment of the present invention will be described.

  FIG. 1 is a diagram illustrating a power supply device using a bending restriction member to which an embodiment of the present invention is applied.

  The power supply device 1 shown in FIG. 1 is a device for electrically connecting a vehicle 5 having a vehicle body 60 and a slide door 50 via a wire harness 110 arranged between the vehicle body 60 and the slide door 50. It is. 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 Inside. 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 direction perpendicular to the paper is the Z direction.

  The power supply 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.

  In the wire harness 110, a portion between the vehicle body 60 and the slide door 50 in the wire harness 110 is passed through a corrugated tube 120 which is a flexible tube made of resin. The bending restricting member 130 is disposed 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 bending regulating member 130 will be described later in detail.

  One end of the corrugated tube 120 on the slide door 50 side is held by the door-side holding portion 140 so as to be swingable 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 section 140 is fixed to the slide door 50. Due to the holding of the corrugated tube 120 by the door-side holding portion 140, a part of the wire harness 110 on the slide door 50 side is held swingably on the XY plane.

  On the other hand, one end of the corrugated tube 120 on the vehicle body 60 side is held by the vehicle body holding portion 150 so as to be swingable 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 unit 150 is fixed to the vehicle body 60. Due to the holding of the corrugated tube 120 by the vehicle body side holding portion 150, a part of the wire harness 110 on the vehicle body 60 side is held swingably on the XY plane.

  When the slide door 50 is fully closed, as shown in FIG. 1, the door-side holding unit 140 is located on the front side of the vehicle 5 with respect to the vehicle-body-side holding unit 150. The corrugated tube 120, that is, the wire harness 110 therein, extends in a substantially linear shape between the vehicle-side holding portion 150 and the door-side holding portion 140. When the slide door 50 is fully opened, the door-side holding portion 140 is located on the rear side of the vehicle 5 with respect to the vehicle-body-side holding portion 150. The wire harness 110 extends from the vehicle-body-side holding portion 150 toward the rear side, and then extends to the door-side holding portion 140 in a substantially linear shape. When the slide door 50 is half-opened between the fully closed state and the fully opened state, it extends in a U-shaped curved shape from the vehicle body side holding portion 150 to the door side holding portion 140 following the opening and closing of the slide door 50.

  At this time, the wire harness 110 is allowed to be curved in the allowable direction D11 that is bent in a U-shape to the outside of the vehicle following the opening and closing of the slide door 50. On the other hand, the curve in the restricting direction D12 that is bent inward on the opposite side is restricted so as not to bend beyond a predetermined limit state. The bending regulating member 130 is a long member provided to perform such regulation.

  FIG. 2 is a diagram showing the bending regulating member shown in FIG. FIG. 3 is a side view of the bending regulating member shown in FIG. 2 as viewed from the direction of arrow V11 in FIG. 2, and a cross-sectional view taken along line V12-V12 in the side view.

  The bending regulating member 130 is attached between the inner surface of the corrugated tube 120 and the wire harness 110 so as to be along the wire harness 110. 2 and 3 show the bending restricting member 130 in an annular state curved in an annular shape in the allowable direction D11.

  The bending restricting member 130 includes a plurality of member pieces 131 arranged in the longitudinal direction D13, and a connecting portion 132 that connects the plurality of member pieces 131 to adjacent ones. In the present embodiment, the plurality of member pieces 131 and the connecting portion 132 are integrally formed of resin. The connecting portion 132 is a flexible portion that is disposed so as to be located inside the curved shape when the wire harness 110 is curved in the allowable direction D11.

  Each of the plurality of member pieces 131 includes a pair of opposing walls 1311 facing each other so as to sandwich the wire harness 110 therebetween, and a coupling wall 1312 connecting the pair of opposing walls 1311 to each other. Each of the member pieces 131 is formed in a substantially C-shaped cross section by these three walls. The space defined by the pair of opposing walls 1311 and the coupling wall 1312 in each of the member pieces 131 continues in the longitudinal direction D13 of the bending regulating member 130, opens toward the outside of the curved shape, and the wire harness fits inside the curved shape. An accommodation groove 133 is formed. The accommodation groove 133 is provided over the entire length of the bending regulating member 130.

  The connecting portion 132 is a plate-shaped member as shown in FIGS. 3 and 4, and is formed thin enough to be able to bend in any of the allowable direction D11 in FIG. 2 and the opposite direction. Have been. Furthermore, the bending restricting member 130 is arranged such that the plate-shaped connecting portion 132 is orthogonal to the XY plane shown in FIG. As a result, the bending of the bending restricting member 130 is restricted on the XY plane (predetermined plane), and as a result, the bending of the wire harness 110 is also restricted on the XY plane.

  Further, a member 131a located at the vehicle body side end of the bending regulating member 130 is held by the vehicle body side holding portion 150 shown in FIG. 1 together with the end of the corrugated tube 120. On the other hand, the member 131b located at the door-side end of the bending regulating member 130 is not held by the door-side holding portion 140 shown in FIG. Thus, the member 131 b can be moved toward and away from the door-side holding portion 140 in accordance with the bending of the bending restricting member 130. The member 131a at the end on the vehicle body side is provided with a flange 131a-1 for holding the member 131a in 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 D11 on the XY plane. The bending restricting member 130 cannot bend beyond the limit state in the restricting direction D12 toward the inside of the vehicle body 60 on the side opposite to the allowable direction D11.

  In the allowable direction D11, as shown in FIGS. 2 and 3, the connecting portions 132 are separated from each other at a curved portion of the plurality of member pieces 131 while being separated from each other on the opposite side to the connecting portions 132. By bending, the bending regulating member 130 can be bent. Thus, the wire harness 110 is allowed to bend in the allowable direction D11.

  On the other hand, in the restricting direction D12, of the plurality of member pieces 131, adjacent ones at the curved portion abut against each other on the side opposite to the connecting portion 132, so that the curving restricting member 130 cannot be bent. The state in which the adjacent ones in the bending portion abut each other is a limit state in bending in the restriction direction D12, and the bending restriction member 130 cannot bend in the restriction direction D12 beyond this limit state. As a result, the bending of the wire harness 110 so as to bend more than the limit state of the bending restricting member 130 in the restricting direction D12 is restricted.

  In the present embodiment, the bending restriction member 130 is configured as follows over substantially the entire length including the door side end 130b in the longitudinal direction D13 of the bending restriction member 130 except for a vehicle body side end 130a described later. ing. That is, when the bending regulating member 130 has a substantially linear shape over substantially the entire length other than the vehicle body side end portion 130a, the adjacent member pieces 131 are configured to contact each other on the side opposite to the connecting portion 132. ing. That is, in the present embodiment, the limit state in the regulation direction D12 is set to a substantially linear shape for portions other than the vehicle body side end portion 130a. Thus, the wire harness 110 maintains a substantially linear shape except for a portion curved in the allowable direction D11.

  Here, as shown in FIG. 1, in the present embodiment, with respect to the vehicle body side end portion 130 a, the curving in the curving direction D <b> 12 is slightly relaxed, and the curving restricting member 130 is bent so that it can bend to some extent. It is configured. Thus, when fully closed, a part of the wire harness 110 in the vicinity of the vehicle-body-side holding portion 150 is slightly curved in the restricting direction D12, and the remaining part has a linear shape parallel to the slide door 50.

  By the way, in the present embodiment, the bending regulating member 130 is formed in an annular state shown in FIGS. 2 and 3. In this annular state, a gap is opened between adjacent member pieces 131. The above-described limit state in the bending in the restricting direction D12 between the vehicle body-side end portion 130a and the other portion including the door-side end portion 130b of the bending restricting member 130 is changed to the member piece 131 when formed in an annular state. Are adjusted depending on how much gaps are formed between them.

  FIG. 4 is a view showing the vehicle-body-side end portion of the bending restricting member in the annular state shown in FIGS. 1 to 3, and FIG. 5 is a view showing the annular state in the annular state shown in FIGS. It is a figure which shows the door side end part of a bending regulating member.

  First, in the bending restricting member 130, the gap d11 (FIG. 2) between the member pieces 131 in the annular state in the main body portion other than the vehicle body side end portion 130a and the door side end portion 130b is changed when the door is fully closed. Is set to be substantially zero when becomes substantially linear.

  On the other hand, as for the vehicle body side end portion 130a, of the end gaps d121 and d122 opened between the member pieces 131 in the annular state, two end gaps d122 from the ends are fully closed and the bending regulating member 130 is closed. Is set wider so that it does not become zero even when it has a substantially linear shape. The remaining end gap d121 is set to the same size as the gap d11 of the member 131 in the main body. In the present embodiment, the member piece 131c adjacent to the member piece 131a at the end on the vehicle body side and the member piece 131d next to the member piece 131d are formed shorter than the other member pieces 131, so that the above-described two end pieces are formed. The gap d122 is set to be wider than the other end gap d121.

  In the door-side end 130b, all the end gaps d13 opened between the member pieces 131 in the annular state are set to be the same size as the gap d11 of the member piece 131 in the main body. .

  With the above setting, the limit state of the bending regulating member 130 is set to a substantially linear shape in other portions including the door side end 130b other than the vehicle body side end 130a. Then, the vehicle body side end portion 130a can be bent in the restricting direction D12 to a limit state where the member pieces 131 contact each other beyond the linear shape.

  The bending restricting member 130 has the annular state shown in FIGS. 2 and 3 and the above-mentioned annular shape in which the vehicle body side end portion 130a is curved to some extent in the restricting direction D12 and the other portion has a substantially linear shape. It can be bent and stretched between a stretched state closer to a linear shape than a state. In the present embodiment, such a bending restricting member 130 is resin-molded using a bending restricting member mold described below.

In addition, a vehicle-body-side lower concave mold 212b is formed on a facing surface 212a of the vehicle-body-side lower mold 212 that faces the vehicle-body-side upper mold 211. The vehicle-body-side upper concave mold 211b and the vehicle-body lower concave mold 212b are concave molds corresponding to the combined outer shape of the vehicle body-side end portion 130a of the curve restricting member 130 and the two vehicle body-side groove molds 213.

  In addition, a door-side upper concave mold 221b is formed on a facing surface 221a of the door-side upper mold 221 facing the door-side lower mold 222. In addition, a door-side lower concave mold 222b is formed on a facing surface 222a of the door-side lower mold 222 that faces the door-side upper mold 221.

  Here, the bending regulating member 130 in the present embodiment is selectively formed from a plurality of types of member candidates having different shapes at both ends or one end according to a desired vehicle type. Here, the shape of both ends or one end referred to in the present embodiment refers to the end gaps d121 and d122 in the vehicle body side end 130a in the annular state when viewed from the bending restriction member 130 to be formed. , The size of the end gap d12 at the door-side end 130b.

  The plurality of types of member candidates that are the population of selection are member groups having different end gaps at both ends or one end. The extent of the bending radius at which both ends or one end of each candidate member can bend in the bending restriction direction is determined by the size of the end gap. In other words, the plurality of types of member candidates are members that have different bending radii that can be bent in the regulating direction at both ends or one end.

  At this time, the bending radius of the bending restriction member 130 to be formed in the restriction direction D12 at both ends or one end is the size or shape of the slide door 50 or the vehicle body 60, that is, the vehicle to which the bending restriction member 130 is applied. It depends on the car model. For this reason, in the present embodiment, the bending regulating member 130 is selectively formed from the plurality of types of candidate members according to the type of the target vehicle.

  Such selective formation is performed by a method for manufacturing a bending restriction member described below.

  FIG. 8 is a schematic flowchart showing a method of manufacturing the bending restriction member for forming the bending restriction member shown in FIGS.

  In this method of manufacturing a bending regulating member, first, a mold preparing step (S11) for preparing the bending regulating member mold 2 shown in FIGS. 6 and 7 is performed. The mold preparation step (S11) is performed in the order of a mold selection step (S111) and a mold assembly step (S112) described below.

  In the die selecting step (S111), the vehicle-side upper die 211 and the vehicle-side lower die 212 are respectively selected from the plural types of vehicle-side upper die candidates 311 and the plural types of vehicle-side lower die candidates 312. . Further, the door-side upper mold 221 and the door-side lower mold 222 are selected from the plurality of types of door-side upper mold candidates 321 and the plurality of types of door-side lower mold candidates 322, respectively. In addition, two vehicle body-side groove molds 213 and two door-side groove molds 223 are selected from the plurality of kinds of vehicle body-side groove mold candidates 313 and the plurality of kinds of door-side groove mold candidates 323, respectively.

  The plurality of types of body-side upper mold candidates 311, the plurality of types of vehicle-side lower mold candidates 312, and the plurality of types of vehicle-side groove mold candidates 313 are the end intervals at the vehicle-side end of each of the above-described plurality of member candidates. , That is, the bending radius on the vehicle body side in a one-to-one correspondence. Further, the plurality of types of door-side upper die candidates 321, the plurality of types of door-side lower die candidates 322, and the plurality of types of door-side groove die candidates 323 are located at the door-side end portions of the plurality of member candidates. , That is, the bending radius on the door side in a one-to-one correspondence. Selection from these mold candidates is performed according to the type of vehicle to which the curving regulating member 130 to be formed is applied.

  In the mold selecting step (S111), the vehicle body upper mold 211, the vehicle body lower mold 212, and the two vehicle body groove molds 213 are selected, respectively, so that the vehicle body constituted by these molds is selected. This is a step of selecting the side end mold 21 (FIG. 6). Similarly, by selecting the door-side upper mold 221, the door-side lower mold 222, and the two door-side groove molds 223, respectively, the door-side end mold 22 ( 6) is selected.

  In the mold assembling step (S112), the vehicle body side upper mold 211 and the door side upper mold 221 selected according to the vehicle type are removably assembled to the common base upper mold 231 independent of the vehicle type. The upper mold 2a is configured. Similarly, the selected lower body mold 212 and the lower body side door mold 222 are detachably assembled to the common base lower mold 232 to form the lower mold 2b. Then, the upper mold 2a and the lower mold 2b are overlapped with the vehicle-side groove mold 213 and the door-side groove mold 223 selected according to the vehicle type, with the shared base groove mold 233 therebetween. The mold 2 for bending control member is assembled.

  The mold assembling step (S112) is performed by combining the vehicle body side end mold 21 and the door side end mold 22 selected in the mold selection step (S111) with the upper base mold 231, the lower base mold 232, and This is a step of detachably assembling with the base mold 23 composed of the base groove mold 233.

  Next, a molding step (S12) of supplying a molten resin to the assembled bending restricting member mold 2 to form the bending restricting member 130, and forming the bending restricting member mold 2 after the resin is solidified. A die cutting step (S13) for disassembly and removal is performed. The bending regulating member 130 is obtained through the die removing step (S13), and the bending regulating member manufacturing method of the present embodiment ends.

  In the bending-regulating member mold 2 and the bending-regulating member manufacturing method of the embodiment described above, the vehicle-side end mold 21 and the door-side end mold 22 are detachably assembled to the base mold 23. It is configured. In other words, according to the present embodiment, for a plurality of types of vehicles, only the body side end die 21 and the door side end die 22 are exchanged and used in accordance with the vehicle type, and the base die occupying the majority. The production cost can be reduced by sharing 23.

  Here, in the present embodiment, the bending regulating member 130 is a member that can be bent and stretched between an annular state and an extended state closer to a linear shape than the annular state. The vehicle body side end mold 21 and the door side end mold 22 are molds for forming the vehicle body side end 130a and the door side end 130b of the curving regulating member 130 in an annular state. In addition, the base mold 23 is a mold for forming another part of the annular bending restricting member 130.
