[First Embodiment]
FIG. 1 is a perspective view of a rod-shaped member 10 as a vehicle body structural member and a wire harness assembly 100A of the first embodiment.

The cylindrical rod-shaped member 10 shown in FIG. 1 is an example of a vehicle body structural member, for example, an instrument panel reinforcement. The rod-shaped member 10 extends in the direction X. The direction X can also be referred to as a longitudinal direction or an axial direction of the rod-shaped member 10. The outer peripheral surface 10a of the rod-shaped member 10 is a cylindrical surface (cylindrical outer surface), and is also a convex curved surface that is convex in the direction Z, that is, outward in the radial direction. The outer peripheral surface 10a is an example of an outer surface extending in the direction X, and is also an example of a convex portion protruding in the direction Z and extending in the direction X. The rod-shaped member 10 is not limited to extending linearly, and may extend while being curved. The direction in which the rod-shaped member 10 extends (longitudinal direction, axial direction, direction X in this embodiment) is an example of the first direction, and the radial outer direction of the rod-shaped member 10 (direction Z in this embodiment) is the second. This is an example of direction.

The wire harness assembly 100A includes a wire harness 200 and an exterior body 300A.

The wire harness 200 is conventionally known and has a plurality of bundled electric wires (not shown).

The exterior body 300A surrounds the wire harness 200 extending in the direction X. In other words, the wire harness 200 penetrates in the accommodation chamber R created by the exterior body 300A in the direction X. The exterior body 300A can enhance the protection of the wire harness 200 and can also be called a protector. In the present embodiment, the exterior body 300A is not a part (component) of the wire harness 200 like the outer skin of the wire harness 200.

The exterior body 300A can be constructed, for example, by bending a sheet made of a synthetic resin material. The sheet is an example of a plate-shaped member.

The sheet is, for example, a thermoplastic foam sheet. The resin material of the thermoplastic resin foam sheet may be a thermoplastic resin material and is not particularly limited. For example, polyethylene resin, polypropylene resin, polycarbonate resin, polyethylene terephthalate resin, polybutylene terephthalate resin, polyamide resin, polyphenylensul. Fide resin, polystyrene resin, polyvinyl chloride resin, polyvinyl acetate resin, polytetrafluoroethylene resin, acrylic resin and the like.

The density of the thermoplastic resin foam sheet is not particularly limited, but is, for example, 200 kg / m ³ or more and 1000 kg / m ³ or less from the viewpoint of preventing anisotropy of mechanical properties and improving the degree of freedom in designing the exterior body 300A. From the viewpoint of further improving the balance between lightness and mechanical strength, ^{it is more preferably 300 kg / m 3} or more and 600 kg / m ³ or less, and 350 kg / m ³ or more and 550 kg / m ³ or less. It is particularly preferable to have.

The thermoplastic resin foam sheet may have a non-foam layer on both sides or one side. That is, the thermoplastic resin foam sheet may have a foam layer and a non-foam layer formed on the foam layer. When the non-foamed layer is formed on the surface of the thermoplastic resin foam sheet in this way, the bending elasticity of the exterior body 300A is improved, and the protection of the wire harness 200 housed in the storage chamber R is further enhanced. .. From the viewpoint of further improving the bending elasticity of the exterior body 300A, a three-layer structure having non-foamed layers on both sides of the thermoplastic resin foamed sheet is preferable. The thickness of the non-foamed layer formed on the thermoplastic resin foam sheet is not particularly limited, but is preferably 10 μm or more and 100 μm or less, for example.

The density of bubbles in the foam layer of the thermoplastic resin foam sheet is not particularly limited, but the lower limit thereof is, for example, 800 cells / mm ³ or more from the viewpoint of more reliably preventing anisotropy of mechanical properties. Is preferable, and 1000 pieces / mm ³ or more is particularly preferable. On the other hand, the upper limit of the number density of bubbles is preferably ^{, for example, 10 10} cells / mm ^{3 or less from the viewpoint of obtaining excellent mechanical strength.}

The thickness of the sheet, which is a thermoplastic resin foam sheet, is not particularly limited, but may be, for example, 0.80 mm or more and 5.0 mm or less from the viewpoint of further improving the balance between ease of bending and mechanical strength. It is preferably 1.0 mm or more and 2.5 mm or less, and particularly preferably.

As shown in FIG. 1, the exterior body 300A has an inner wall 310, an outer wall 320, and two side walls 330, 340.

The inner wall 310 has a substantially constant thickness, bends along the outer peripheral surface 10a of the rod-shaped member 10 to cover the outer peripheral surface 10a at least partially, and follows the direction Y, that is, the circumferential direction of the outer peripheral surface 10a. At a predetermined height, it extends in the direction X. The inner surface 310c of the inner wall 310 faces the outer peripheral surface 10a and extends in the direction X along the outer peripheral surface 10a. The inner surface 310c may be in contact with the outer peripheral surface 10a at least partially. In other words, a gap may be provided at least partially between the inner surface 310c and the outer peripheral surface 10a. The inner surface 310c facing the outer peripheral surface 10a, which is the outer surface of the cylinder, is the inner surface of the cylinder, and the inner wall 310 has a partially cylindrical shape, for example, a half-pipe shape. Further, the width of the inner wall 310 along the direction Y is substantially constant. The direction Y is an example of the width direction (short direction) of the inner wall 310.

The outer wall 320 has a substantially constant thickness, is bent along the outer peripheral surface 10a at a position separated from the inner wall 310 in the direction Z, that is, radially outward of the outer peripheral surface 10a, and has a predetermined width along the direction Y. And it extends in the direction X. The height of the gap in the direction Z between the inner wall 310 and the outer wall 320 is substantially constant. The outer wall 320 has a partially cylindrical shape, for example, a half-pipe shape. Further, the width of the outer wall 320 along the direction Y is substantially constant. The direction Y is an example of the width direction (short direction) of the outer wall 320. The direction Z is an example in the thickness direction of the inner wall 310 and the outer wall 320, and in the height direction of the accommodation chamber R. Further, the direction Y is also an example in the width direction of the accommodation chamber R.

Of the two widthwise ends 310a and 310b of the inner wall 310, one end 310a, that is, the left end 310a (end edge) in FIG. 1, extends in the direction X. Further, of the two end portions 320a and 320b in the width direction of the outer wall 320, one end portion 320a, that is, the left end portion 320a (end edge) in FIG. 1 extends in the direction X. Further, the end portion 320a of the outer wall 320 is located away from the end portion 310a of the inner wall 310 in the direction Y.

The side wall 330 connects the end 310a and the end 320a. The side wall 330 has a substantially constant thickness, extends substantially along the direction Z (the radial direction of the outer peripheral surface 10a), and extends in the direction X with a predetermined width along the direction Z. The width of the side wall 330 is substantially the same as the height of the gap between the inner wall 310 and the outer wall 320. The side wall 330 is one of the first side wall and the second side wall, and is an example of the first side wall.

Of the two widthwise ends 310a and 310b of the inner wall 310, the other end 310b, that is, the right end 310b (edge) in FIG. 1, extends in the direction X. Further, of the two end portions 320a and 320b in the width direction of the outer wall 320, the other end portion 320b, that is, the right end portion 320b (end edge) in FIG. 1 extends in the direction X. Further, the end portion 320b of the outer wall 320 is located away from the end portion 310b of the inner wall 310 in the direction Y.

The side wall 340 connects the end 310b and the end 320b. The side wall 340 has a substantially constant thickness, extends substantially along the direction Z (the radial direction of the outer peripheral surface 10a), and extends in the direction X with a predetermined width along the direction Z. The width of the side wall 340 is substantially the same as the height of the gap between the inner wall 310 and the outer wall 320. The side wall 340 is the other of the first side wall and the second side wall, and is an example of the second side wall.

Further, the side wall 340 is formed by overlapping a superimposing portion connected to the inner wall 310 and a superimposing portion connected to the outer wall 320. A closed cross section (surrounding shape) of the exterior body 300A is formed by, at least partially, connecting these superposed portions that overlap each other by, for example, engagement, adhesion, or connection by a binder. The overlapping portion may also be referred to as a coupling region.

The exterior body 300A is provided with a storage chamber R surrounded by an inner wall 310, an outer wall 320, and two side walls 330 and 340. The accommodation chamber R is bent along the outer peripheral surface 10a, extends in the direction X with a predetermined width along the direction Y and a predetermined height along the direction Z. Here, the height H of the accommodation chamber R along the direction Z is smaller (shorter) than the width of the accommodation chamber R along the direction Y. That is, the distance (height H) between the inner wall 310 and the outer wall 320 is shorter than the width W of the inner wall 310 along the direction Y. With such a configuration, the exterior body 300A and the accommodation chamber R have a relatively thin shape extending along the direction Y and extending in the direction X.

The wire harness 200 penetrates the accommodation chamber R in the direction X. In the accommodation chamber R, the wire harness 200 extends in the direction X in a state of being convexly curved in the direction Z (outward in the radial direction of the outer peripheral surface 10a) along the shape of the accommodation chamber R.

The exterior body 300A may have a shape bent along the outer peripheral surface 10a before being integrated with the wire harness 200. In other words, the exterior body 300A is formed in a bent shape along the outer peripheral surface 10a, and the wire harness 200 is penetrated in the direction X in the bent accommodation chamber R, so that the exterior body 300A has a bent shape. The wire harness assembly 100A may be made. Alternatively, the exterior body 300A may be bent along the outer peripheral surface 10a after being integrated with the wire harness 200. For example, the exterior body 300A is formed into a flat shape without bending along the outer peripheral surface 10a, and the wire harness 200 is penetrated into the flat storage chamber R to form the wire harness assembly 100A. When the 100A is attached to the rod-shaped member 10, it may be bent along the outer peripheral surface 10a.

The wire harness assembly 100A can be attached to the rod-shaped member 10 or a vehicle body component other than the rod-shaped member 10 by various attachment members. The mounting member may be provided integrally with the exterior body 300A, or may be a member different from the wire harness assembly 100A. A mounting member different from the wire harness assembly 100A is, for example, a binding band that binds the wire harness assembly 100A and the rod-shaped member 10 in a state where the wire harness assembly 100A partially covers the outer peripheral surface 10a of the rod-shaped member 10. , Clamps, etc. (not shown).

As described above, the wire harness assembly 100A of the first embodiment is provided along the rod-shaped member 10 (body structure member) extending in the direction X (first direction), and the wire harness 200 and the wire harness are provided. The exterior body 300A surrounding the 200 is provided. The rod-shaped member 10 has an outer peripheral surface 10a (outer surface) extending in the direction X. The outer peripheral surface 10a (convex portion) projects in the direction Z (diameterally outward, second direction) intersecting the direction X and extends in the direction X. The exterior body 300A has an inner wall 310, an outer wall 320, a side wall 330 (first side wall), and a side wall 340 (second side wall). The inner wall 310 bends along the outer peripheral surface 10a to cover the outer peripheral surface 10a and extends in the direction X with a predetermined width. The outer wall 320 is bent along the outer peripheral surface 10a at a position separated from the inner wall 310 in the direction Z (outward in the radial direction) and extends in the direction X with a predetermined width. The side wall 330 connects one end 310a in the width direction of the inner wall 310 and one end 320a in the width direction of the outer wall 320, and extends in the direction X. The side wall 340 connects the other end 310b in the width direction of the inner wall 310 and the other end 320b in the width direction of the outer wall 320, and extends in the direction X. A storage chamber R is provided in the exterior body 300A. The accommodation chamber R is surrounded by the inner wall 310, the outer wall 320, the side wall 330, and the side wall 340, and bends along the outer peripheral surface 10a and extends in the direction X. The wire harness 200 penetrates the accommodation chamber R in the direction X.

Further, in the exterior body 300A of the first embodiment, the accommodation chamber R surrounded by the inner wall 310, the outer wall 320, the side wall 330, and the side wall 340 bends along the outer peripheral surface 10a and extends in the direction X. .. The wire harness 200 penetrates the accommodation chamber R in the direction X.

According to such a configuration, for example, since the exterior body 300A extends in the direction X in a state of being bent along the outer peripheral surface 10a, the exterior body 300A is not bent along the outer peripheral surface 10a as compared with the configuration. It is possible to prevent the exterior body 300A and thus the wire harness assembly 100A from becoming bulky. In other words, according to the above configuration, the wire harness assembly 100A can be arranged along the outer peripheral surface 10a (convex portion) of the rod-shaped member 10 with less bulkiness.

Further, in the wire harness assembly 100A of the first embodiment, the distance (height H) between the inner wall 310 and the outer wall 320 is shorter than the width W in the width direction of the inner wall 310.

According to such a configuration, for example, the exterior body 300A can be made thinner in the direction Z, so that the wire harness assembly 100A can be formed along the outer peripheral surface 10a (convex portion) of the rod-shaped member 10 without being further bulky. Can be arranged.

Further, in the wire harness assembly 100A of the first embodiment, the exterior body 300A is made by bending a plate-shaped member.

According to such a configuration, for example, the exterior body 300A and thus the wire harness assembly 100A can be realized by a relatively simple configuration. Therefore, for example, the labor and cost of manufacturing the wire harness assembly 100A can be further reduced.

Further, as shown in FIG. 2, in the present embodiment, the mounting member 400 connects the region Ao1 and the region Ao2 (see FIG. 3) of the inner wall 310 between the side wall 330 and the side wall 340. That is, the mounting member 400 also functions as a connecting member.

FIG. 3 is a developed view of the exterior body 300B. As shown in FIG. 3, also in this embodiment, the exterior body 300B is made by bending the thermoplastic resin foam sheet 300S.

Fold curves L1 to L4 extending in the direction X and parallel to each other are provided between the regions. By folding the thermoplastic resin foam sheet 300S of FIG. 3 in a mountain fold on the folding curve L1 at the line of sight of FIG. 3, a closed cross section (surrounding shape) of the exterior body 300B as shown in FIG. 2 is formed.

The regions Ao1 and Ao2 at both ends of the thermoplastic resin foam sheet 300S in the direction intersecting the direction X are superimposed on the direction Z in the intermediate portion of the inner wall 310 in the direction Y, that is, the intermediate portion in the width direction of the inner wall 310, and the mounting member 400 It is a site that is connected via. The regions Ao1 and Ao2 can also be referred to as a superimposing portion or a coupling region. The overlapping positions of the regions Ao1 and the regions Ao2 may be opposite to those in FIG.

The thermoplastic resin foam sheet 300S is provided with through holes 300a1 and 300a2 through which the mounting member 400 penetrates. The through holes 300a1 and 300a2 have, for example, an oval shape.

As shown in FIG. 2, in the closed cross section (surrounding shape) of the exterior body 300B, the through holes 300a1 provided in the region Ao1 of the region A310 (inner wall 310) and the region Ao2 of the region A310 (inner wall 310) are provided. The through hole 300a2 overlaps with the through hole 300a2 in the direction Z. The mounting member 400 is coupled to the region Ao1 in a state of penetrating the two through holes 300a1 and 300a2 in the direction Z.

Further, the regions Ao1 and the regions Ao2 are fitted by using, for example, an adhesive means such as an adhesive or an adhesive tape, a welding means such as ultrasonic welding or heat welding, a locking member, or a rivet in a state where the regions Ao1 and the region Ao2 are overlapped with each other. It can be connected by a combination means, a penetrating fixing means using a hotchkiss or the like.

FIG. 4 is an exploded perspective view of the mounting member 400, and FIG. 5 is an exploded side view of the mounting member. As shown in FIGS. 4 and 5, the mounting member 400 has a first engaging portion 410 attached to the exterior body 300B and a second engaging portion 420 attached to the rod-shaped member 10.

The first engaging portion 410 is arranged in the bottom portion 411 arranged inside the through hole 300a2 in the region Ao2 as shown in FIG. 2 and in the through hole 300a1 in the region Ao1 as shown in FIG. From the upper surface of FIG. 5 of the standing portion 412, which is provided narrower than the width in the direction Y of 411 and protrudes upward from the bottom portion 411 in FIGS. 4 and 5, and the insertion portion 424 described later can be inserted. An insertion hole 413 that is recessed downward is provided. The height H1 of the bottom portion 411 and the height H2 of the upright portion 412 are set to be the same or substantially the same height.

The second engaging portion 420 has a base portion 421 formed to have the same width as or substantially the same width as the bottom portion 411 and arranged along the outer surface of the region Ao1 as shown in FIG. 2, the bottom portion 411, the standing portion 412, and the base portion 420. A pillar portion 422 provided narrower than the width in the direction Y of the base portion 421 and extending upward in FIG. 5 from the base portion 421, and a vane portion 423 provided so as to project from the upper tip of the pillar portion 422 to both sides. It has an insertion portion 424 extending downward from the base portion 421 in FIG. The vane portion 423 is configured to be elastically deformable so that it can be inserted into a mounting hole (not shown) of the rod-shaped member 10 and can be locked after being inserted. When the insertion portion 424 is inserted into the insertion hole 413, the tip portion elastically deforms inward, and when it gets over the locking portion 413a of the insertion hole 413, it elastically returns and abuts on the peripheral edge of the locking portion 413a to lock. .. When the insertion portion 424 is locked to the locking portion 413a, the upper end of the standing portion 412 comes into contact with the lower surface of the base portion 421, and the first engaging portion 410 and the second engaging portion 420 are locked.

As shown in FIG. 2, in a state where the first engaging portion 410 and the second engaging portion 420 are integrated, the bottom portion 411 of the first engaging portion 410 and the base portion 421 of the second engaging portion 420 By sandwiching the area Ao1, the mounting member 400 is coupled to the area Ao1, that is, the inner wall 310.

Further, as shown in FIG. 2, in the state where the mounting member 400 is assembled, the bottom portion 411 of the first engaging portion 410 is housed in the through hole 300a1 and does not project into the accommodation chamber R. With such a configuration, interference between the wire harness 200 in the accommodation chamber R and the mounting member 400 is suppressed. The through hole 300a1 may also be referred to as a relief portion.

As described above, the wire harness assembly 100B of the second embodiment has a mounting member 400. The mounting member 400 is fixed to the inner wall 310 and mounted on the rod-shaped member 10 (body structure member).

According to such a configuration, for example, as compared with the case where the wire harness assembly 100B is attached to the rod-shaped member 10 by using a mounting member different from the wire harness assembly 100B, it takes time and effort to manage the parts of the mounting member and the mounting work. It is possible to reduce the trouble of.

[Third Embodiment]
FIG. 6 is a perspective view of the exterior body 300C included in the wire harness assembly 100C of the third embodiment. As shown in FIG. 6, in the present embodiment, the cross-sectional shape (for example, outer diameter) of the outer peripheral surface 10a of the rod-shaped member 10 (not shown) changes toward the direction X, and the cross-sectional shape of the outer peripheral surface 10a is changed. In response to the change, the cross-sectional shape of the exterior body 300C extending in the direction X along the outer peripheral surface 10a and orthogonal to the direction X also changes in the direction X. As an example, the exterior body 300C has a plurality of portions 300C1 to 300C5 (sections) having different cross-sectional shapes orthogonal to the direction X. The average diameters of the inner wall 310 and the outer wall 320 (containment chamber R) of the parts 300C1, 300C2, 300C3 are different from each other, and in the parts 300C2, 300C4, the average diameters of the inner wall 310 and the outer wall 320 (containment chamber R) toward the direction X Is gradually changing.

According to such a configuration, for example, there is less bulkiness along a rod-shaped member (body component, not shown) whose cross-sectional shape orthogonal to the direction X of the outer peripheral surface (outer surface) changes toward the direction X. The wire harness assembly 100C can be realized.

[Fourth Embodiment]
FIG. 7 is a perspective view of the wire harness assembly 100D of the fourth embodiment. As shown in FIG. 7, in the present embodiment, a part of another member 11 such as a stay connected to the rod-shaped member 10 projects as a protrusion 11a on the outer peripheral surface 10a (outer surface). The wire harness assembly 100D has a plurality of exterior bodies 300D1, 300D2 (300D) separated in the direction X, and the wire harness 200 is not covered by the exterior body and is exposed between the plurality of exterior bodies 300D1, 300D2. ing. The wire harness 200 is arranged so as to avoid the protrusion 11a.

According to such a configuration, it is possible to prevent the exterior body 300D and thus the wire harness assembly 100D from becoming bulky by covering the protrusions 11a on the outer peripheral surface 10a (outer surface). The number of the plurality of exterior bodies 300D separated from each other may be 3 or more.
