Description

Wire harness

[0001] The present invention relates to a wire harness.

[0002] Conventionally, vehicles such as automobiles are equipped with a power supply device for a sliding door that electrically connects a power source (such as a secondary battery) on the vehicle body side to switches and electrical components on the sliding door side. In this power supply device for a sliding door, the electrical connection is performed by a wire harness. This wire harness has a crossover section of an electric wire that spans between the vehicle body and the sliding door, with one end of the crossover section fixed to a fixed section on the vehicle body side and the other end of the crossover section fixed to a fixed section on the door side. The crossover section is routed along an arm member of a link mechanism that also spans between the vehicle body and the sliding door. For example, Patent Document 1 listed below discloses a wire harness in which the crossover section passes through the arm member.

[0003] Japanese Patent Application Laid-Open No. 2017-1514

[0004] In this wire harness, the shortest path connecting the vehicle body-side fixed portion and the door-side fixed portion varies depending on the open / closed position of the sliding door relative to the vehicle body. Therefore, in the wire harness, when the shortest path between the vehicle body-side fixed portion and the door-side fixed portion is longest, the electric wires are routed without slack between the vehicle body-side fixed portion and the door-side fixed portion, and the path length of the electric wires is set as the length of the crossing portion. Here, the path length of the electric wires routed without slack between the vehicle body-side fixed portion and the door-side fixed portion is shorter when the shortest path between the vehicle body-side fixed portion and the door-side fixed portion is shortest than when the shortest path between the vehicle body-side fixed portion and the door-side fixed portion is longest. Therefore, the excess length of the crossing portion appears as an excess length when the shortest path between the vehicle body-side fixed portion and the door-side fixed portion is shortest. In conventional wire harnesses, the excess length of the crossing portion may detract from the appearance of the wires.

[0005] Therefore, an object of the present invention is to provide a wire harness that can improve the appearance.

[0006] The present invention provides a harness body including a crossover section that is supported at one end on the vehicle body via a vehicle body-side rotating shaft having an axial direction in the vertical direction and that is stretched along an arm member having the other end supported on the sliding door via a door-side rotating shaft having an axial direction in the vertical direction, a vehicle body-side routing section that is routed at a tip of the vehicle body-side end of the crossover section, and a door-side routing section that is routed at a tip of the door-side end of the crossover section, a vehicle body-side assembly structure that assembles the crossover section to the vehicle body, and a door-side assembly structure that assembles the crossover section to the sliding door, The arm member has a bottom wall with a groove bottom facing the door opening direction or the door closing direction of the sliding door, a pair of side walls that are vertically extended from each end of the bottom wall in the same direction in the door opening / closing direction of the sliding door and extend toward the sliding door beyond the bottom wall, and a blocking wall that closes openings formed by each end of the pair of side walls on the vertically extending side, leaving a first opening on the vehicle body side, and the crossing portion passes through a cylindrical portion formed by the bottom wall, the pair of side walls, and the blocking wall, the harness slide member is arranged in a region vertically below the second harness holding member, and pulls the harness slide member in the door opening / closing direction and pulls it vertically upward, sliding the harness slide member along the axial direction; and the harness slide member is fixed to the sliding door, and receives a force input from the harness slide member to the harness slide member during the door opening / closing operation of the sliding door, thereby sliding the harness slide member in the door opening / closing direction.

[0007] In the wire harness according to the present invention, the transition portion passes through the tubular portion of the arm member, thereby preventing deterioration of the appearance due to exposure of the transition portion and improving the appearance. Furthermore, the wire harness according to the present invention includes a harness slide member and a guide rail, and in conjunction with the opening and closing of the sliding door, the transition portion pulled out from the second opening of the arm member is slid by the harness slide member, while the harness slide member slides in the door opening and closing direction along the guide rail. Therefore, this wire harness can absorb excess length of the transition portion when the door is opened and closed, and the location where the excess length is absorbed can be controlled to the side of the sliding door where the harness slide member and harness holding portion are located, thereby improving the appearance.

Fig. 2 is a plan view of the wire harness according to an embodiment, seen from above the vehicle, showing a state where the door is fully open.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a wire harness according to the present invention will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to these embodiments.

[0010] [Embodiment] One embodiment of a wire harness according to the present invention will be described with reference to Figs.

[0011] 1 to 4, reference numeral 1 denotes a wire harness according to this embodiment.

[0012] For example, a vehicle such as an automobile is known that is equipped with a sliding door 520 that can slide (move back and forth in a sliding direction) relative to a vehicle body 510. In this vehicle, a link mechanism provided with an arm member 610 or the like is interposed between the vehicle body 510 and the sliding door 520, and by operating this link mechanism, the sliding door 520 is opened and closed relative to the vehicle body 510 between a door fully closed position and a door fully open position.

[0013] One end of the arm member 610 is pivotally supported by the vehicle body 510 via a rotation shaft 621 on the vehicle body 510 side (hereinafter referred to as the "vehicle body-side rotation shaft") whose axial direction is the vertical direction (FIGS. 1 to 4). A first arm holding member 622 is fixed to the vehicle body 510, which holds one end of the arm member 610 rotatably around the axis of the vehicle body-side rotation shaft 621. The other end of the arm member 610 is pivotally supported by the sliding door 520 via a rotation shaft 623 on the sliding door 520 side (hereinafter referred to as the "door-side rotation shaft") whose axial direction is the vertical direction (FIGS. 1 to 4). A second arm holding member 624 is fixed to the sliding door 520, which holds the other end of the arm member 610 rotatably around the axis of the door-side rotation shaft 623.

[0014] The arm member 610 has a bottom wall 611 whose groove bottom faces the door-opening or door-closing direction of the sliding door 520, a pair of side walls 612 that hang down from each vertical end of the bottom wall 611 in the same direction in the door-opening or door-closing direction of the sliding door 520 and extend toward the sliding door 520 beyond the bottom wall 611, and a blocking wall 613 that closes the openings formed by the vertical ends of the pair of side walls 612, 612 except for a first opening 610a on the vehicle body 510 side ( FIGS. 1 to 4 ). Thus, the arm member 610 has a second opening 610b adjacent to the bottom wall 611 on the sliding door 520 side, and a cylindrical portion 614 formed by the bottom wall 611, the pair of side walls 612, 612, and the blocking wall 613 ( FIGS. 1 to 4 ).

[0015] The arm member 610 shown here has a bottom wall 611 with the groove bottom facing the door opening direction ( FIGS. 1 to 4 ). The arm member 610 shown here has the bottom wall 611, side wall 612, and closing wall 613 formed in the shape of rectangular flat plates ( FIGS. 1 to 4 ). Therefore, in this arm member 610, the tubular portion 614 is shaped like a square tube, and the first opening 610a and the second opening 610b are rectangular. For ease of explanation, the wall of the arm member 610 facing the door closing direction is referred to as the bottom wall 611, and the wall facing the door opening direction is referred to as the closing wall 613. However, the wall facing the door opening direction may also be referred to as the bottom wall 611, and the wall facing the door closing direction may also be referred to as the closing wall 613.

[0016] This vehicle is equipped with a power supply device for a sliding door that supplies power from a power source (such as a secondary battery) on the vehicle body 510 to electrical connection objects on the sliding door 520. The electrical connection objects are installed on the sliding door 520, such as electrical components and switches. For example, the electrical components of the sliding door 520 refer to a drive device for operating a power window, a speaker, etc. Furthermore, the switches of the sliding door 520 refer to switches for operating a power window, a power seat, etc. The power supply device for a sliding door includes a wire harness 1 that electrically connects the power source on the vehicle body 510 to the electrical connection objects on the sliding door 520.

[0017] The wire harness 1 includes a harness body 10 having one end electrically connected to a power source and the other end electrically connected to an object to be electrically connected (FIGS. 1 to 4). The harness body 10 may be a bundle of multiple electric wires, or multiple electric wires covered and protected by an exterior member such as a corrugated tube.

[0018] The harness main body 10 has a bridge portion 11 that is stretched along the arm member 610 between the vehicle body 510 and the sliding door 520, a vehicle body-side routing portion 12 that is routed at one end of the bridge portion 11 (hereinafter referred to as the "vehicle body-side end"), and a door-side routing portion 13 that is routed at the other end of the bridge portion 11 (hereinafter referred to as the "door-side end") (Figures 1 to 4).

[0019] The crossover portion 11 is passed through the inside of the tubular portion 614 of the arm member 610 and is stretched between the vehicle body 510 and the sliding door 520 ( FIGS. 1 to 4 ). The wire harness 1 includes a vehicle-body-side assembly structure 20 that assembles the crossover portion 11 to the vehicle body 510, and a door-side assembly structure 30 that assembles the crossover portion 11 to the sliding door 520 ( FIGS. 1 to 4 ). The crossover portion 11 passes through the inside of the tubular portion 614 and is drawn out from a first opening 610 a of the arm member 610 toward the vehicle-body-side assembly structure 20, and is also drawn out from a second opening 610 b of the arm member 610 toward the door-side assembly structure 30.

[0020] In this manner, the arm member 610 causes the transition portion 11, which passes through the cylindrical portion 614, to be pulled outward from the first opening 610a and the second opening 610b at both ends of the cylindrical portion 614. Therefore, it is desirable to set the position and length of the cylindrical portion 614 (i.e., the positions and lengths of the bottom wall 611 and the closing wall 613) so that the transition portion 11 can maintain a predetermined bending radius or greater throughout the entire trajectory of the arm member 610 during the door opening and closing operation. The predetermined bending radius is the minimum bending radius that can be achieved without applying an excessive load to the transition portion 11 (e.g., without applying excessive compressive stress or tensile stress). It is also desirable to form the end of the closing wall 613 on the first opening 610a side and the end of the bottom wall 611 on the second opening 610b side into an arc shape, for example, so that they are curved outward, and to form both ends of the cylindrical portion 614 in a trumpet shape in the cylindrical axis direction. As a result, in this arm member 610, it is possible to prevent the transition portion 11 being pulled out from the first opening 610a or the second opening 610b from getting caught, and to prevent a decrease in the durability of the transition portion 11.

[0021] The vehicle body-side assembly structure 20 includes a first harness holding member 21 that holds the vehicle body-side end of the transition portion 11 and maintains it in position (FIGS. 1 to 4). The first harness holding member 21 is fixed to the vehicle body 510. The first harness holding member 21 shown here routes the vehicle body-side end of the transition portion 11, which is pulled out from the first opening 610a of the arm member 610, in the door opening and closing direction. For example, the first harness holding member 21 is shaped so that the transition portion 11 is inserted axially through a through hole, and the peaks and valleys of the inner peripheral surface of the through hole are fitted into the peaks and valleys of the bellows portion of the corrugated tube at the vehicle body-side end of the transition portion 11, thereby maintaining the vehicle body-side end in position.

[0022] The vehicle body side assembly structure 20 shown here is disposed on the door opening direction side of one end of the arm member 610 .

[0023] The door-side assembly structure 30 includes a second harness holding member 31 that holds the door-side end of the transition portion 11 and maintains it in position (see FIGS. 1 to 4 ). The second harness holding member 31 is fixed to the sliding door 520. The second harness holding member 31 shown here pulls in and holds the door-side end of the transition portion 11, which has been pulled out through the second opening 610b of the arm member 610, from vertically below, and then pulls the transition portion 11 vertically upward toward the door-side wiring portion 13. For example, the second harness holding member 31 is shaped so that the transition portion 11 is inserted axially through a through hole, and the peaks and valleys of the bellows portion of the corrugated tube at the door-side end of the transition portion 11 fit into the valleys and valleys of the inner circumferential surface of the through hole to maintain the door-side end in position.

[0024] The door-side assembly structure 30 further includes a harness slide member 32 (FIGS. 1 to 4) that is positioned vertically below the second harness holding member 31 and that pulls the transition portion 11, which is pulled out from the second opening 610b of the arm member 610, in the door opening / closing direction and pulls it vertically upward, while sliding the transition portion 11 along the axial direction. The door-side assembly structure 30 also includes a guide rail 33 that is fixed to the sliding door 520 and receives a force input from the transition portion 11 to the harness slide member 32 during the door opening / closing operation, thereby sliding the harness slide member 32 in the door opening / closing direction (FIGS. 1 to 4). The harness slide member 32 slides in the door opening / closing direction to absorb excess length of the transition portion 11, as described below.

[0025] The harness slide member 32 holds the crossing portion 11 pulled out from the second opening 610b of the arm member 610 so that it can move freely in the axial direction, and guides the door-side end of the crossing portion 11 pulled out vertically upward to the second harness holding member 31. The harness slide member 32 is provided with a T-shaped guided portion 32a (FIG. 1). The guide rail 33 has a guide groove 33a that fits into the guided portion 32a and guides it in the door opening and closing direction (FIGS. 1 and 3).

[0026] The door-side assembly structure 30 shown here is disposed on the door closing direction side of the other end of the arm member 610 .

[0027] For example, in this wire harness 1, if the harness slide member 32 and the guide rail 33 are not present, the path length of the crossover portion 11 connecting the first harness holding member 21 and the second harness holding member 31 via the shortest path is shortest when the door is in the fully open position, and the path length of the crossover portion 11 connecting the first harness holding member 21 and the second harness holding member 31 via the shortest path is longest when the door is in the fully closed position. In such a wire harness 1, the crossover portion 11 is set to the path length when the door is in the fully closed position. Therefore, in the crossover portion 11, excess length increases like slack as the sliding door 520 in the fully closed position moves in the door opening direction, and the excess length is maximized when the door is in the fully open position.

[0028] However, in this wire harness 1, the transition portion 11 is passed through the tubular portion 614 between one end and the other end of the arm member 610, so that the deterioration of the appearance due to the exposure of the transition portion 11 is suppressed and the appearance can be improved.

[0029] Furthermore, in this wire harness 1, when slack occurs in the transition portion 11 due to excess length as the sliding door 520 is opened or closed, a force acts on this transition portion 11. Here, in this example, the distance between the first opening 610a of the arm member 610 and the first harness holding member 21 is large enough to prevent slack from occurring in the transition portion 11 therebetween, and when a force acts on the transition portion 11 when the door is opened or closed, slack may occur due to excess length in the portion pulled out from the second opening 610b of the arm member 610.

[0030] However, since this wire harness 1 includes the harness slide member 32 and the guide rail 33, when the sliding door 520 in the fully closed position moves in the door opening direction, a force is applied to the harness slide member 32 from the crossing portion 11 drawn out from the second opening 610b, and this crossing portion 11 slides vertically downward within the harness slide member 32, pushing the harness slide member 32 in the door closing direction. In other words, the crossing portion 11 slides vertically downward on the harness slide member 32 in conjunction with the movement of the sliding door 520 in the fully closed position in the door opening direction, pushing the harness slide member 32 in the door closing direction along the guide rail 33, so that the increasing trajectory of slack caused by the excess length generated at that time can be controlled without applying excessive tensile or compressive force.

[0031] Furthermore, in this wire harness 1, when the sliding door 520 in the fully open position moves in the door closing direction, a force is applied to the harness slide member 32 from the crossing portion 11 drawn out from the second opening 610b, and this crossing portion 11 slides vertically upward within the harness slide member 32, pushing the harness slide member 32 in the door opening direction. In other words, the crossing portion 11 slides vertically upward on the harness slide member 32 in conjunction with the movement of the sliding door 520 in the fully open position in the door closing direction, pushing the harness slide member 32 along the guide rail 33 in the door opening direction, thereby allowing the reduction of slack due to excess length to be accommodated.

[0032] In this way, this wire harness 1 can absorb the excess length of the bridge portion 11 when the door is opened or closed, and the location where the excess length is absorbed can be controlled to the side of the sliding door 520 where the harness slide member 32 and the guide rail 33 are present, thereby improving the appearance.

[0033] Here, the harness slide member 32 is positioned vertically below the second harness holding member 31 on the guide rail 33 when the door is in the fully open position, and is positioned on the guide rail 33 at the side furthest in the door opening direction when the door is in the fully closed position. In other words, the harness slide member 32 reciprocates between the position furthest in the door closing direction, directly below the second harness holding member 31, and the position furthest in the door opening direction, in conjunction with the opening and closing operation of the sliding door 520.

[0034] The door-side assembly structure 30 further includes an elastic member 34 that applies a tensile load in the door closing direction as a preload to the harness slide member 32 when the door is in the fully open position (FIGS. 1 to 4).

[0035] One end of this elastic member 34 is connected to the harness slide member 32 ( FIGS. 1 to 4 ). The harness slide member 32 is provided with a holding portion 32b that holds one end of the elastic member 34 ( FIGS. 2 and 4 ). The door-side assembly structure 30 is provided with a holding member 35 that holds the other end of the elastic member 34 on the door closing direction side of the guide rail 33 ( FIGS. 1 to 4 ). Here, a helical spring is used as the elastic member 34. One end of the elastic member 34 is hooked and held by the holding portion 32b of the harness slide member 32, and the other end is hooked and held by the holding member 35.

[0036] The elastic member 34 applies a tensile load in the door closing direction to the harness slide member 32 when the door is in the fully closed position. Therefore, in the wire harness 1, when the sliding door 520 in the fully open position moves in the door closing direction, the transition portion 11 pushes the harness slide member 32 in the door opening direction along the guide rail 33, thereby stretching the elastic member 34 and increasing the tensile load. As a result, in the wire harness 1, when the sliding door 520 in the fully closed position moves in the door opening direction, the elastic member 34 assists the movement of the harness slide member 32 in the door closing direction. Therefore, in the wire harness 1, even if the rigidity of the harness main body 10 changes due to a change in ambient temperature or even if the rigidity of the harness main body 10 increases due to an increase in the number of circuits (i.e., an increase in the number of wires), the movement of the harness slide member 32 in the door opening / closing direction can be stabilized, and thus stable slack absorption is possible. Furthermore, in this wire harness 1, the elastic member 34 applies tension to the bridge portion 11 via the harness slide member 32, so that the generation of abnormal noise due to vibration or the like can be suppressed.

[0037] As described above, the wire harness 1 of the present embodiment can improve its appearance.

[0038] Incidentally, in this wire harness 1, the crossover portion 11 may be slid in the axial direction of the tube portion 614 in conjunction with the opening and closing of the sliding door 520. In this case, the distance between the first opening 610a of the arm member 610 and the first harness holding member 21 is set to a size that allows slack to be generated in the crossover portion 11 therebetween. In this wire harness 1, when the sliding door 520, which is in the fully closed position, moves in the door opening direction, the crossover portion 11 can be slid in the axial direction within the tube portion 614 to release the force acting on the crossover portion 11. However, slack may occur due to excess length in the crossover portion 11 pulled out from the first opening 610a and the crossover portion 11 pulled out from the second opening 610b.

[0039] However, as described above, in this wire harness 1, when the sliding door 520 in the fully closed position moves in the door opening direction, a force is applied to the harness slide member 32 from the crossover portion 11 drawn out from the second opening 610b, and this crossover portion 11 slides vertically downward inside the harness slide member 32, pushing the harness slide member 32 in the door closing direction. In other words, in conjunction with the movement of the sliding door 520 in the fully closed position in the door opening direction, the crossover portion 11 slides inside the tube portion 614 and also slides vertically downward inside the harness slide member 32, pushing the harness slide member 32 along the guide rail 33 in the door closing direction.

[0040] As described above, when the sliding door 520 in the fully open position moves in the door closing direction, a force is applied to the harness slide member 32 from the crossover portion 11 drawn out from the second opening 610b of the wire harness 1, and the crossover portion 11 slides vertically upward inside the harness slide member 32, pushing the harness slide member 32 in the door opening direction. In other words, the crossover portion 11 slides inside the tube portion 614 in conjunction with the movement of the sliding door 520 in the fully open position in the door closing direction, and slides vertically upward on the harness slide member 32, pushing the harness slide member 32 along the guide rail 33 in the door opening direction.

[0041] In this way, the wire harness 1 can improve its appearance by sliding the crossover portion 11 inside the tubular portion 614 in conjunction with the door opening and closing operation, thereby preventing deterioration in appearance due to exposure of the crossover portion 11. The wire harness 1 can absorb the excess length of the crossover portion 11 when the door is opened and closed, and the location where the excess length is absorbed can be controlled to the side of the sliding door 520 where the harness slide member 32 and the guide rail 33 are present, thereby improving the appearance.
