Description

[Technical field]

[0001] The present invention relates to an exterior body for protecting wires arranged in a vehicle or the like. [Background technology]

[0002] Patent Document 1 describes a method for assembling a wire harness, which is configured by bundling a plurality of electric wires, to a reinforcing member arranged on the back side of a vehicle's instrument panel. Specifically, Patent Document 1 describes a method in which an interference suppression member that suppresses contact between the reinforcing member and the wire harness is first attached to the reinforcing member, and then the wire harness is attached to the interference suppression member via a clamp that has been attached to the wire harness in advance.

[0003] [Patent Document 1] JP 2020-73373 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the method described in Patent Document 1, since an interference suppression member is disposed between the reinforcing member and the wire harness, there is a problem that the installation height of the wire harness becomes high due to the presence of this interference suppression member. In other words, a large so-called installation space must be secured for the wire harness that is routed along the outer surface of the reinforcing member. In addition, since the internal space on the back side of the instrument panel is limited, if the wire harness is attached using the above-mentioned installation structure, there is a possibility that interference will occur between the wire harness and other components located around it, and it may become difficult to arrange the other components.

[0005] The present invention has been made in consideration of the above-mentioned problems, and aims to provide an exterior body that can be connected to a rod-shaped reinforcing member arranged in the internal space on the back side of a vehicle's instrument panel, for example, and that can protect at least one wire while keeping it separate from the reinforcing member, and can be wired along the axial direction of the reinforcing member in a relatively narrow space around the reinforcing member. [Means for solving the problem]

[0006] The inventors discovered that by constructing an exterior body by overlapping an arch-shaped outer shell member having a longer arch length than an arch-shaped inner shell member that is attached to the outer periphery of the mounting portion, and arranging at least one wire in the wiring space partitioned by these outer shell member and inner shell member, it is possible to protect the at least one wire while keeping it separate from the reinforcing member, and to wire the at least one wire along the axial direction of the reinforcing member in a relatively narrow space around the reinforcing member, thereby completing the present invention.

[0007] In order to achieve the above object, the gist of the present invention is as follows. (1) The present invention provides an exterior body configured to be attached to a rod-shaped attachment part with at least one wire disposed therein, the exterior body comprising: an arch-shaped outer shell member having a first opening extending along the axial direction of the attachment part; and an arch-shaped inner shell member having a second opening extending along the axial direction and having an arch length shorter than the arch length of the outer shell member, the arch-shaped inner shell member being disposed inside the outer shell member with the second opening oriented in the same direction as the first opening, wherein a wiring space is defined by the inner surface of the outer shell member and the outer surface of the inner shell member, and in which the at least one wire is disposed, the attachment part is disposed inside the inner shell member, the outer shell member and the inner shell member are at least partially integrated by bonding, and the exterior body is configured such that a size of the wiring space changes when the opening widths of the first opening and the second opening are changed.

[0008] (2) The exterior body described in (1) above is configured such that an external force is applied in a direction that expands the opening widths of the first opening and the second opening, thereby elastically deforming the outer shell member and the inner shell member, thereby increasing the distance between the outer shell member and the inner shell member that constitute the wiring space, and an elastic restoring force acting in a direction that narrows the opening widths of the first opening and the second opening decreases the distance between the outer shell member and the inner shell member that constitute the wiring space.

[0009] (3) The exterior body according to (1) or (2) above, wherein at least one of the outer shell member and the inner shell member has a deformable portion that makes the shell member easily deformable.

[0010] (4) The outer casing is an outer casing as described in (3) above, wherein the easily deformable portion is formed as a plurality of recesses extending linearly in the axial direction and having a thin plate thickness in at least one of the outer shell member and the inner shell member.

[0011] (5) An exterior body as described in any one of (1) to (4) above, in which at least one of the inner surface of the outer shell member and the outer surface of the inner shell member, which face each other across the wiring space, has a movement suppression portion that suppresses movement of the wire within the wiring space.

[0012] (6) The outer casing described in any one of (1) to (5) above, further comprising a locking member that suppresses movement of the inner shell member relative to the attachment portion arranged inside the inner shell member.

[0013] (7) The exterior body according to any one of (1) to (6) above, wherein at least one of the outer shell member and the inner shell member is made of resin.

[0014] (8) The exterior body according to (7) above, wherein the resin is a foamed resin. Effect of the Invention

[0017] Next, an exterior body according to an embodiment of the present invention will be described below.

[0018] <First embodiment> (Exterior body) FIG. 1 is a cross-sectional view showing an example of an exterior body according to a first embodiment of the present invention. The exterior body 1 shown in FIG. 1 is configured to be attached to a rod-shaped attachment part 3 (shown by a dashed line in FIG. 1) with at least one wire 2 (shown by a two-dot chain line in FIG. 1) arranged inside. Examples of the "wire" mentioned above include electric wires and cables, and in addition to these, examples of the "attached part" include a wire bundle and a wire harness in which a plurality of electric wires or a plurality of cables are bundled together. The "attached part" mentioned above may be rod-shaped or may have such a rod-shaped part, and is not particularly limited, but may be, for example, a rod-shaped reinforcing member arranged in the internal space on the back side of the instrument panel of a vehicle, or a reinforcing member having such a rod-shaped part. That is, the exterior body 1 extends in the axial direction of the attachment part 3, and the geometric central axis C of the exterior body 1 is substantially parallel to the axis of the attachment part 3. In addition, the exterior body 1 is configured to be detachable from the attachment part 3 having the above-mentioned configuration, as described below. Such a reinforcing member is sometimes called an instrument panel reinforcement.

[0019] Exterior body 1 comprises an outer shell member 4 and an inner shell member 5 as main components.

[0020] (Outer shell material) The outer shell member 4 has a first opening 6 extending along the axial direction of the attachment portion 3, and the outer shape of the outer shell member 4 is formed in an arch shape when viewed in a cross section perpendicular to the central axis C shown in FIG. 1. Specifically, in the exterior body 1 of the embodiment shown in FIG. 1, the outer shape of the outer shell member 4 is formed in a smoothly curved arch shape. Here, the arch shape means a ring shape with ends, that is, a cylindrical shape in which the edges 7, 8 of the first opening 6 are separated from each other in the cross section shown in FIG. 1 and are not closed in a ring shape. Specifically, examples of the arch shape include a C-shape, a U-shape, and a horseshoe shape. In the embodiment shown in FIG. 1, the opening width W1 of the first opening 6 is designed to be narrower than the outer dimensions of the attachment portion 3 (diameter dimension in FIG. 1). This is to prevent the exterior body 1 attached to the attachment portion 3 from falling off.

[0021] The material constituting the outer shell member 4 may be any material capable of elastic deformation, and is not particularly limited, but examples thereof include resin, etc. Thermoplastic resins are preferable in terms of moldability, processability, weldability, adhesiveness, etc. Examples of thermoplastic resins include polyethylene resin, polypropylene resin, polycarbonate resin, polyethylene terephthalate resin, polybutylene terephthalate resin, polyamide resin, polyphenylene sulfide resin, polystyrene resin, polyvinyl chloride resin, polyvinyl acetate resin, polytetrafluoroethylene resin, acrylic resin, etc.

[0022] Moreover, the resin is preferably a foamed resin. By using a foamed resin as the material for the outer shell member 4, the weight can be reduced compared to when the outer shell member 4 is made of a solid resin, and the bending elastic modulus of the outer shell member 4 can be reduced. In other words, the outer shell member 4 and the exterior body 1 formed by the outer shell member 4 can be softened, and the exterior body 1 can be easily elastically deformed to arrange or insert the wire 2 into the wiring space described below. In addition, the exterior body 1 can be easily elastically deformed to attach the exterior body 1 to the attachment portion 3, and the elastically deformed exterior body 1 can be easily restored to its original shape by its elastic restoring force. Furthermore, damage and wear of the wire 2 inserted or arranged in the wiring space due to repeated contact between the exterior member 4 and the wire 2 can be prevented or suppressed.

[0023] The foam density of the foamed resin is not particularly limited, but is, for example, 200 kg / m 3 More than 1000kg / m 3 In particular, in order to improve the balance of the ease of elastic deformation, light weight, mechanical strength, etc. of the exterior body 1, the foam density of the foamed resin is preferably 250 kg / m 3 More than 600kg / m 3 More preferably, the range is 300 kg / m 3 More than 550kg / m 3 The following ranges are particularly preferred:

[0024] The thickness of the outer shell member 4 is not particularly limited, but in order to further improve the balance of performance such as ease of elastic deformation of the outer shell member 4, weight reduction, and mechanical strength, it is preferable that the thickness be in the range of, for example, 0.50 mm or more and 5.0 mm or less, and more preferably in the range of 1.0 mm or more and 2.0 mm or less.

[0025] (Inner shell material) The inner shell member 5 has a second opening 9 extending along the axial direction of the mounting portion 3 and is formed in an arch shape. In the example shown in FIG. 1, the outer shape of the inner shell member 5 is a smoothly curved arch shape, similar to the outer shell member 4. The opening width W2 of the second opening 9 may be set to be approximately the same as the opening width W1 of the first opening 6, or may be set to be slightly wider or narrower. In the embodiment shown in FIG. 1, the opening widths W1 and W2 are formed to be approximately the same opening width.

[0026] The arch length of the inner shell member 5 is set to be shorter than the arch length of the outer shell member 4. Here, the arch length means the creepage distance measured along the outer surfaces of the outer shell member 4 and the inner shell member 5 in the cross-sectional view shown in FIG.

[0027] The material constituting the inner shell member 5 may be any material capable of elastic deformation, and is not particularly limited, but examples thereof include resins. The resin may be the same thermoplastic resin as that mentioned in the description of the outer shell member 4. The resin is preferably the foamed resin. By using a foamed resin as the material constituting the inner shell member 5, the weight can be reduced compared to the case where the inner shell member 5 is made of a solid resin, and the bending elastic modulus of the inner shell member 5 can be reduced. In other words, the inner shell member 5 and the exterior body 1 constituted by the inner shell member 5 can be softened, and the exterior body 1 can be easily elastically deformed to arrange or insert the wire 2 in the wiring space described above. In addition, the exterior body 1 can be elastically deformed to attach the exterior body 1 to the attachment portion 3, and the elastically deformed exterior body 1 can be easily restored to its original shape by its elastic restoring force. Furthermore, damage and wear of the wire 2 caused by repeated contact between the wire 2 inserted or arranged in the wiring space 12 and the inner shell member 5 can be prevented or suppressed. Similarly, damage and wear of the mounted portion 3 due to repeated contact between the mounted portion 3 in the mounting space 13 and the inner shell member 5 can be prevented or suppressed.

[0028] It is preferable that at least one of the outer shell member 4 and the inner shell member 5 is made of the above-mentioned resin, and more preferable that both are made of the above-mentioned resin. If both the outer shell member 4 and the inner shell member 5 are made of the above-mentioned resin, the exterior body 1 can be easily elastically deformed compared to a case where one of them is made of the above-mentioned resin and the other is made of a material harder than the above-mentioned resin. It is also preferable that at least one of the outer shell member 4 and the inner shell member 5 is made of the above-mentioned foamed resin, and more preferable that both are made of the above-mentioned foamed resin. If both the outer shell member 4 and the inner shell member 5 are made of the above-mentioned foamed resin, the exterior body 1 can be more easily elastically deformed compared to a case where both the outer shell member 4 and the inner shell member 5 are made of the above-mentioned resin. In addition, wear of the wire 2, the attached portion 3, and the like due to repeated contact with the outer shell member 4 and the inner shell member 5 can be further prevented or suppressed.

[0029] The plate thickness of the inner shell member 5 is not particularly limited, but in order to further improve the balance of performance such as ease of elastic deformation of the inner shell member 5, weight reduction, and mechanical strength, it is preferable that the plate thickness be in the range of, for example, 0.50 mm or more and 5.0 mm or less, and more preferably in the range of 1.0 mm or more and 2.0 mm or less.

[0030] The inner shell member 5 is disposed inside the outer shell member 4 with the first opening 6 and the second opening 9 facing the same direction. Specifically, the inner shell member 5 is disposed inside the outer shell member 4 with edges 10, 11 of the second opening 9 in the inner shell member 5 substantially overlapping edges 7, 8 of the outer shell member 4. In other words, the inner shell member 5 is disposed inside the outer shell member 4 with the inner shell member 5 biased toward the first opening 6 with respect to the space on the inner surface side of the outer shell member 4.

[0031] At least a part of the outer shell member 4 and the inner shell member 5 are joined together and integrated. Specifically, one edge 7 of the edges 7, 8 of the outer shell member 4 and one edge 10 of the edges 10, 11 of the inner shell member 5 that faces or contacts the edge 7 are joined together and integrated. Similarly, the other edge 8 of the edges 7, 8 of the outer shell member 4 and the other edge 11 of the edges 10, 11 of the inner shell member 5 that faces or contacts the edge 8 are joined together and integrated. In other words, the above-mentioned "at least a part of them" means the edges 7, 10 that face each other or the edges 8, 11 that contact each other. The means or method for joining the outer shell member 4 and the inner shell member 5 may be a conventionally known joining means or method, and may be, for example, ultrasonic welding, adhesive, double-sided tape, riveting, bolting, etc.

[0032] As shown in FIG. 1, a wiring space 12 is defined by the inner surface of the outer shell member 4 and the outer surface of the inner shell member 5, and at least one wire 2 is disposed therein. The wiring space 12 extends along the central axis C of the exterior body 1. Since the exterior body 1 is made of an elastically deformable material as described above, the size of the wiring space 12 changes when the opening widths W1, W2 of the first opening 6 and the second opening 9 are changed, as will be described in detail later. Specifically, by applying an external force to the exterior body 1 in a direction that expands the opening widths W1, W2 of the first opening 6 and the second opening 9, the outer shell member 4 and the inner shell member 5 are elastically deformed, so that the distance between the outer shell member 4 and the inner shell member 5 that constitute the wiring space 12, i.e., the height H of the wiring space, can be increased, and the distance H between the outer shell member 4 and the inner shell member 5 that constitute the wiring space 12 can be reduced by an elastic restoring force that acts in a direction that narrows the opening widths W1, W2 of the first opening 6 and the second opening 9. That is, when the above-mentioned external force is applied to the exterior body 1, wiring space 12 becomes wider overall and height H increases, compared to when the above-mentioned external force is not applied to the exterior body 1. On the other hand, when the above-mentioned external force is removed, the exterior body 1 returns to its original shape due to its elastic restoring force, and wiring space 12 becomes narrower overall and height H decreases. Note that Fig. 1 shows a state in which no external force is being applied to the exterior body 1.

[0033] An attachment space 13 for arranging (accommodating) the attachment portion 3 is formed on the inner surface side of the inner shell member 5. Therefore, when the exterior body 1 is attached to the attachment portion 3, the exterior body 1 is aligned with the attachment portion 3 or wrapped around the attachment portion 3.

[0034] Next, an example of a manufacturing method of the exterior body 1 according to the first embodiment of the present invention will be described. First, a material plate made of the above-mentioned resin or foamed resin is prepared, and then punched to form the outer plate 14 that will become the outer shell member 4 and the inner plate 15 that will become the inner shell member 5. The punching process may be a conventionally known punching process, such as Thomson processing.

[0035] FIG. 2 is a perspective view showing an example of an outer plate 14 and an inner plate 15 formed by punching out a material plate. In FIG. 2, the length of each plate 14, 15 in the direction indicated by the arrow L1 (hereinafter referred to as the L1 direction) corresponds to the arch length described above. Therefore, by changing the length of each plate 14, 15 in the L1 direction, the arch length of each of the outer shell member 4 and the inner shell member 5 can be changed. In the example shown here, the length of the outer plate 14 in the L1 direction is set to be longer than that of the inner plate 15. Also, by changing the lengths of the plates 14, 15, that is, the difference or ratio between the lengths of the plates 14, 15, the height H of the wiring space 12 in the completed state of the exterior body 1 shown in FIG. 1 can be changed. Also, the direction indicated by the arrow L2 (hereinafter referred to as the L2 direction) corresponds to the direction in which the central axis C of the exterior body 1 and the axis of the mounting portion 3 in the completed state shown in FIG. 1 extend. In FIG. 2, the lengths of the plates 14, 15 in the L2 direction are set to be substantially the same, and the plate thicknesses of the plates 14, 15 are set to be substantially the same.

[0036] Next, the plates 14, 15 are overlapped with each other. Also, in order to position the outer plate 14 outside the inner plate 15, the plates 14, 15 are bent or folded into an arch shape so that one edge 7 of the outer plate 14 and one edge 10 of the inner plate 15 are substantially aligned with each other, and the other edge 8 of the outer plate 14 and the other edge 11 of the inner plate 15 are substantially aligned with each other. The aligned edges 7 and 10, as well as the edges 8 and 11, are then joined together. In this manner, the exterior body 1 shown in FIG. 1 is constructed.

[0037] The action and effect of the exterior body 1 according to the embodiment of the present invention will be described. When an external force is applied to the exterior body 1 in a direction that expands the opening width of the opening of the exterior body 1 shown in FIG. 1, that is, the opening widths W1 and W2 of the above-mentioned openings 6 and 9, the exterior shell member 4 and the inner shell member 5 constituting the exterior body 1 are elastically deformed from an arch shape to approach the shapes (flat shape) of the outer plate 14 and the inner plate 15 before the exterior body 1 is deformed into an arch shape. Since the arch length of the exterior shell member 4 is longer than that of the inner shell member 5, for example, as shown in FIG. 3, when the inner shell member 5 is elastically deformed to become flat, the exterior shell member 4 is elastically deformed to be greatly separated (in a mountain shape) from the outer surface of the inner shell member 5 by the difference in arch length from the inner shell member 5. As a result, the distance between the inner surface of the exterior shell member 4 and the outer surface of the inner shell member 5 is increased compared to the distance between the inner surface of the exterior shell member 4 and the outer surface of the inner shell member 5 in the arch-shaped exterior body 1 shown in FIG. 1.

[0038] In this way, by applying the above-mentioned external force to exterior body 1, the gap between outer shell member 4 and inner shell member 5 is increased and height H of wiring space 12 is increased, so that not only wire 2 but also a relatively large component such as a connector connected to a wire can easily pass through wiring space 12. Furthermore, since exterior body 1 has a rounded, flat triangular shape as shown in Fig. 3, even if the space between the attached portion 3 and the components surrounding it is narrow, for example, one edge 7, 10 of edges 7, 8, 10, 11 of exterior body 1 can be inserted into the space and exterior body 1 can be wrapped around the outer periphery of attached portion 3.

[0039] When the external force is removed, the elastic restoring force acts in a direction narrowing the opening widths W1 and W2 of the first opening 6 and the second opening 9 of the exterior body 1, and the gap between the exterior shell member 4 and the inner shell member 5 constituting the wiring space 12 decreases. Specifically, when the external force is removed, the elastic restoring force causes the exterior shell member 4 and the inner shell member 5 to deform in a direction returning to an arch shape. As a result, the exterior body 1 returns from the rounded flat triangular shape shown in FIG. 3 to the arch shape shown in FIG. 1, the wiring space 12 becomes crescent-shaped, and the height H of the wiring space 12 decreases as shown in FIG. 1. As a result, that is, during the restoration process, the exterior body 1 is wrapped around the outer periphery of the attachment portion 3, and the attachment portion 3 is disposed within the attachment space 13.

[0040] In this manner, according to the present disclosure, for example, the exterior body 1 can be connected to the mounting portion 3, which is a rod-shaped reinforcing member arranged in the internal space on the back side of the instrument panel of a vehicle. In other words, since the exterior body 1 can be attached in a state where it is aligned with the mounting portion 3, the installation space of the exterior body 1 can be reduced compared to the conventional configuration. Furthermore, since at least one wire 2 is arranged in the wiring space 12 and the exterior body 1 is connected to the mounting portion 3 in this state, the wire 2 can be protected in a state separated from the mounting portion 3. Moreover, since the height H of the wiring space 12 in the state shown in FIG. 1 where the exterior body 1 is attached to the mounting portion 3 is lower than the height H of the wiring space 12 in the state shown in FIG. 3, the wire can be wired along the axial direction of the mounting portion 3 in a relatively narrow space that exists around the mounting portion 3. Furthermore, in the state shown in FIG. 1, the wire 2 is sandwiched between the inner surface of the outer shell member 4 and the outer surface of the inner shell member 5 that form the wiring space 12, or the narrowness of the wiring space 12 makes it difficult for the wire 2 to move inside it. Therefore, wear and damage to the wire 2 caused by movement of the wire 2 within the wiring space 12 can be prevented or suppressed.

[0041] <Second embodiment> FIG. 4 is a cross-sectional view showing an example of an exterior body according to a second embodiment of the present invention, and FIG. 5 is a perspective view of an example of an exterior body according to a second embodiment of the present invention. In the exterior body 1A of the second embodiment shown in FIG. 4 and FIG. 5, the same components as those of the exterior body 1 of the first embodiment are denoted by the same reference numerals and their description is omitted. The exterior body 1A of the second embodiment shown in FIG. 4 and FIG. 5 shows a configuration in which at least one of the outer shell member 4 and the inner shell member 5 has an easily deformable portion 16 that makes the exterior body 1A easily deformable when an external force is applied in a direction that expands the opening widths W1 and W2 of the first opening 6 and the second opening 9, and is a preferred embodiment. In addition, although an example in which the easily deformable portion 16 is formed on both the outer surface of the outer shell member 4 and the outer surface of the inner shell member 5, an easily deformable portion that makes the exterior body 1A easily deformable may be formed on one of the outer shell member 4 and the inner shell member 5.

[0042] The easily deformable portions 16 are preferably formed as a plurality of recesses extending linearly in the axial direction and having a thin plate thickness in at least one of the outer shell member 4 and the inner shell member 5. The easily deformable portions 16 are preferably formed on the outer surface of the outer shell member 4. The easily deformable portions 16 are preferably substantially parallel to each other, and the intervals between the easily deformable portions 16 are preferably set to be substantially constant. The easily deformable portions 16 may be formed so as to extend continuously along the central axis C, as shown in FIG. 5. Alternatively, they may be formed so as to extend intermittently along the central axis C.

[0043] The easily deformable parts 16 can be formed, for example, by cutting the shell member 4 or the outer plate 14 constituting the shell member 4, or by making cuts in the shell member 4 or the outer plate 14. Alternatively, the easily deformable parts 16 may be slits or holes formed penetrating the shell member 4 or the outer plate 14 in the plate thickness direction. In short, the easily deformable parts 16 are configured to reduce the rigidity and strength of the shell member 4 or the outer plate 14 in the part where the easily deformable parts 16 are formed, and to easily cause elastic deformation of the shell member 4 or the outer plate 14 as a whole. In other words, the easily deformable parts 16 can be said to be fragile parts. Therefore, by increasing or decreasing the number and depth of the easily deformable parts 16, it is possible to easily cause elastic deformation in the shell member 4 or the outer plate 14, or to make it difficult to cause elastic deformation. For example, when the number and depth of the easily deformable parts 16 are increased, the shell member 4 or the outer plate 14 can be easily elastically deformed compared to when the number and depth of the easily deformable parts 16 are small and shallow.

[0044] The portions between the easily deformable portions 16 in the outer shell member 4 form panels extending along the central axis C. Therefore, as shown in Figs. 4 and 5, the outer shell member 4 has a polygonal shape with the portions where the easily deformable portions 16 are formed as corners. When the number of easily deformable portions 16 formed in the outer shell member 4 is increased, the width of each panel along the arch length of the outer shell member 4 narrows in the cross-sectional view shown in Fig. 4, so that the outer shell member 4 as a whole has a rounded or curved shape. In contrast, when the number of easily deformable portions 16 formed in the outer shell member 4 is decreased, the width of each panel expands in the cross-sectional view shown in Fig. 4, so that the outer shell member 4 as a whole has a so-called angular shape.

[0045] Similarly to the outer shell member 4, easily deformable portions 16 that make the inner shell member 5 easily deformable are formed on the outer surface of the inner shell member 5. That is, the easily deformable portions 16 are formed as a plurality of recesses that extend linearly in the axial direction and have a thin plate thickness. As shown in Figs. 4 and 5, the easily deformable portions 16 are substantially parallel to each other, and the intervals between the easily deformable portions 16 are set to be substantially constant. The easily deformable portions 16 may be formed so as to extend continuously along the central axis C, as shown in Fig. 5. Alternatively, they may be formed so as to extend intermittently along the central axis C.

[0046] The portions between the easily deformable parts 16 in the inner shell member 5 are panels extending along the central axis C. Therefore, as shown in Figs. 4 and 5, the inner shell member 5 has a polygonal shape with the parts where the easily deformable parts 16 are formed as corners, similar to the outer shell member 4. Therefore, when the number of easily deformable parts 16 formed in the inner shell member 5 is increased, the width of each panel along the arch length of the inner shell member 5 narrows in the cross-sectional view shown in Fig. 4, so that the inner shell member 5 has a rounded or curved shape as a whole. On the other hand, when the number of easily deformable parts 16 formed in the inner shell member 5 is decreased, the width of each panel expands in the cross-sectional view shown in Fig. 4, so that the inner shell member 5 has a so-called angular shape as a whole. In other words, by increasing or decreasing the number of easily deformable parts 16 formed on the outer surface of the inner shell member 5, the shape of the inner shell member 5 can be made to follow the outer shape of the attachment part 3. Since other configurations are similar to those shown in FIGS. 1 to 3, the same parts as those shown in FIGS. 1 to 3 are designated by the same reference numerals as those in FIGS. 1 to 3 and the description thereof will be omitted.

[0047] An example of a manufacturing method of the exterior body 1A according to the second embodiment of the present invention will be described. First, a material plate made of the above-mentioned resin or foamed resin is prepared, and punched to form the outer plate 14 that will become the outer shell member 4 and the inner plate 15 that will become the inner shell member 5. Almost simultaneously, the easily deformable portion 16 is formed in each of the plates 14, 15. Examples of the punching process include punching processes called so-called Thompson punching and Wiggle punching. With such punching, the easily deformable portion 16 can be formed in each of the plates 14, 15 almost simultaneously when the plates 14, 15 are punched out from the material plate.

[0048] FIG. 6 is a perspective view showing an example of the outer plate 14 and the inner plate 15. In FIG. 6, the length of each plate 14, 15 in the L1 direction corresponds to the arch length of each shell member 4, 5 in the completed state of the exterior body 1A shown in FIG. 4 or FIG. 5, and the L2 direction in which the easily deformable portion 16 extends corresponds to the axial direction of the mounting portion 3. In the example shown here, the height H of the wiring space 12 in the completed state of the exterior body 1A shown in FIG. 4 or FIG. 5 can be changed by changing the length of each plate 14, 15 in the L1 direction, that is, the difference or ratio between the lengths of each plate 14, 15. In FIG. 6, the length of each plate 14, 15 in the L2 direction is set to be approximately the same, and the plate thickness of each plate 14, 15 is set to be approximately the same.

[0049] Next, the surface of the inner plate 15 on which the easily deformable portion 16 is formed and the surface of the outer plate 14 on which the easily deformable portion 16 is not formed are overlapped with each other. Then, each plate 14, 15 is bent or folded in an arch shape so that the outer plate 14 is positioned outside the inner plate 15, so that one edge 7 of the outer plate 14 and one edge 10 of the inner plate 15 are substantially aligned, and the other edge 8 of the outer plate 14 and the other edge 11 of the inner plate 15 are substantially aligned. In the second embodiment, since the easily deformable portion 16 is formed on the outer surface of each plate 14, 15, each plate 14, 15 can be easily bent or folded compared to the first embodiment. Also, the edges 7, 8, 10, 11 are joined to each other while being substantially aligned with each other. In this manner, the exterior body 1A shown in FIG. 4 and FIG. 5 is constructed.

[0050] The action and effect of the exterior body 1A according to the second embodiment of the present invention will be described. As described above, the exterior body 1A according to the second embodiment has the easily deformable portion 16 formed on the outer surface of each of the shell members 4 and 5, and is therefore more susceptible to elastic deformation than the exterior body 1 according to the first embodiment. Therefore, the exterior body 1A according to the second embodiment can be easily elastically deformed by an external force smaller than the above-mentioned external force that elastically deforms the exterior body 1 according to the first embodiment.

[0051] That is, when an external force is applied to the exterior body 1A in a direction that expands the opening widths W1 and W2 of the exterior body 1A shown in Fig. 4 and Fig. 5, the exterior shell member 4 and the inner shell member 5 constituting the exterior body 1A are elastically deformed from an arch shape to approach the shapes (flat shape) of the outer plate 14 and the inner plate 15 before the exterior body 1A is deformed into an arch shape. Since the arch length of the exterior shell member 4 is longer than that of the inner shell member 5, for example, as shown in Fig. 7, when the inner shell member 5 is elastically deformed to become flat, the exterior shell member 4 is elastically deformed to be largely separated (in a mountain shape) from the outer surface of the inner shell member 5 by the difference in arch length from the inner shell member 5. As a result, the distance between the inner surface of the exterior shell member 4 and the outer surface of the inner shell member 5 is increased compared to the distance between the inner surface of the exterior shell member 4 and the outer surface of the inner shell member 5 in the arch-shaped exterior body 1A shown in Fig. 4 and Fig. 5.

[0052] In this way, by applying the above-mentioned external force to exterior body 1A to increase the gap between outer shell member 4 and inner shell member 5 and to increase height H of wiring space 12, not only wire 2 but also a relatively large member such as a connector connected to wire 2 can easily pass through wiring space 12, as in the first embodiment. Furthermore, since exterior body 1A has a rounded, flat triangular shape as shown in Fig. 7, even if the space between the attached portion 3 and the surrounding members is narrow, for example, one edge 7, 10 of edges 7, 8, 10, 11 of exterior body 1A can be inserted into the space and exterior body 1A can be wrapped around the outer periphery of attached portion 3.

[0053] When the external force is removed, the elastic restoring force acts in a direction narrowing the opening widths W1 and W2 of the first opening 6 and the second opening 9 of the exterior body 1A, and the gap between the exterior shell member 4 and the inner shell member 5 constituting the wiring space 12 decreases. Specifically, when the external force is removed, the elastic restoring force of the exterior shell member 4 and the inner shell member 5 deforms in a direction returning to an arch shape. As a result, the exterior body 1A returns from the rounded flat triangular shape shown in FIG. 7 to an arch shape as shown in FIG. 4 or FIG. 5, the wiring space 12 becomes crescent-shaped, and the height H of the wiring space 12 decreases as shown in FIG. 4 or FIG. 5. As a result, that is, during the restoration process, the exterior body 1A is wrapped around the outer periphery of the attachment portion 3, and the attachment portion 3 is disposed within the attachment space 13.

[0054] In this way, according to the present disclosure, for example, the exterior body 1A can be connected to the mounting portion 3, which is a rod-shaped reinforcing member arranged in the internal space on the back side of the instrument panel of a vehicle. In other words, since the exterior body 1A can be attached in a state where it is aligned with the mounting portion 3, the installation space of the exterior body 1A can be reduced compared to the conventional configuration. Furthermore, since at least one wire 2 is arranged in the wiring space 12 and the exterior body 1A is connected to the mounting portion 3 in this state, the wire 2 can be protected in a state separated from the mounting portion 3. FIG. 8 shows this state. Moreover, the height H of the wiring space 12 in the state shown in FIG. 4 or FIG. 5 where the exterior body 1A is attached to the mounting portion 3 is lower than the height H of the wiring space 12 in the state shown in FIG. 7, the wire 2 can be wired along the axial direction of the mounting portion 3 in a relatively narrow space existing around the mounting portion 3. 4, 5, and 8, the wire 2 is sandwiched between the inner surface of the outer shell member 4 and the outer surface of the inner shell member 5 that form the wiring space 12, or the narrowness of the wiring space 12 makes it difficult for the wire 2 to move inside the wiring space 12. Therefore, wear and damage to the wire 2 caused by the movement of the wire 2 in the wiring space 12 can be prevented or suppressed. In the second embodiment, the outer shell member 4 and the inner shell member 5 both form a polygon with the part where the easily deformable portion 16 is formed as a corner, so that the wire 2 can be arranged by running along the panel of the outer shell member 4 or the inner shell member 5 in the wiring space 12. That is, the arrangement position of the wire 2 can be almost determined, and thus the risk of the wire 2 being displaced in the wiring space 12 can be reduced. In addition, since a flat panel is formed on the outer surface of the outer shell member 4, a fixing member such as a tape-wrapped clamp can be easily attached to the panel by welding, tape, or the like. Then, by fitting the protruding portion of the tape winding clamp into a mounting hole formed in the vehicle, the exterior body 1A can be easily fixed to the vehicle.

[0055] In this way, the outer casing 1A of the second embodiment can be easily elastically deformed by an external force smaller than that of the outer casing 1 of the first embodiment, and can obtain substantially the same functions and effects as the outer casing 1 of the first embodiment.

[0056] <Third embodiment> FIG. 9 is a perspective view showing an example of an exterior body according to the third embodiment of the present invention. Each of the exterior shell member 4 and the inner shell member 5 of the exterior body 1B shown here may be made of so-called plastic cardboard. The inner shell member 5 will be described as an example. The inner plate 15 constituting the inner shell member 5 has a pair of flat liners 18 and a plurality of elongated plate-like ribs 17, and is configured by sandwiching the plurality of ribs 17 that are approximately parallel to each other and arranged at regular intervals between the pair of liners 18. Therefore, a space extending in the length direction of the ribs 17 is formed between the adjacent ribs 17. The portion of each liner 18 corresponding to the above-mentioned space is not particularly supported by the rib 17. Therefore, the portion corresponding to the above-mentioned space is configured to be more easily deformed than the portion where the rib 17 is provided. The easily deformed portion is configured to function as the easily deformed portion 16. The outer plate 14 constituting the exterior shell member 4 is also made of plastic cardboard, similar to the inner plate 15. The plate thickness of each plate 14, 15 is, for example, 1.5 mm to 7.0 mm, and the above-mentioned interval is preferably about several mm. Moreover, each of the liners 18 and the ribs 17 is preferably made of the above-mentioned resin or foamed resin.

[0057] Then, the plates 14, 15 made of plastic cardboard are used to construct the exterior body 1B shown in Fig. 9 by the above manufacturing method. When forming the exterior body 1B shown in Fig. 9 from the state in which the plates 14, 15 are stacked and integrated, if a flat jig or the like is applied to the stacked and integrated plates 14, 15 to deform them, the part to function as the easily deformable portion 16 can be specified, and the exterior body 1B in the designed shape can be obtained. Also, instead of using a jig, a marking line may be formed on the stacked and integrated plates 14, 15, or the plates 14, 15 on which marking lines have been formed in advance may be integrated, and this may be used to form the exterior body 1B.

[0058] In the exterior body 1B shown in FIG. 9, among the portions of the plates 14, 15 corresponding to the space, the portions deformed by a jig, a marking line, or the like function as the easily deformable portion 16. Therefore, similarly to the exterior body 1A according to the second embodiment, the exterior body 1B shown in FIG. 9 is easily elastically deformed by the above-mentioned external force. Therefore, the exterior body 1B shown in FIG. 9 can obtain substantially the same action and effect as the exterior body 1A according to the second embodiment. Moreover, in the exterior body 1B shown in FIG. 9, since the plates 14, 15 are made of plastic cardboard, the exterior body 1B is less likely to deform in a direction perpendicular to the central axis C. Therefore, the wires 2 arranged in the wiring space 12 can be protected more effectively.

[0059] Although the first to third embodiments of the present invention have been described above, the present invention is not limited to the above-mentioned embodiments, and includes all aspects included in the concept of the present invention and the scope of the claims, and can be modified in various ways within the scope of the present invention. For example, in the exterior bodies 1, 1A, and 1B according to the respective embodiments, at least one of the inner surface of the outer shell member 4 and the outer surface of the inner shell member 5, which face each other across the wiring space 12, may be provided with a movement suppressing portion that suppresses the movement of the wire 2 in the wiring space 12. Examples of the movement suppressing portion include a partition portion or a cushion configured to divide the wiring space 12 into at least two in the arch length direction. By dividing the wiring space 12, the position of the wire 2 in the wiring space 12 can be approximately determined, and as a result, wear of the wire 2 due to the movement of the wire 2 in the wiring space 12 can be further prevented or suppressed.

[0060] <Fourth embodiment> Specifically, Fig. 10 is a cross-sectional view showing an example of an exterior body according to a fourth embodiment of the present invention. The example shown in Fig. 10 is an example in which partitions 19 are provided as movement suppressing parts in wiring space 12 of exterior body 1A. As shown in Fig. 10, three partitions 19 are provided at predetermined intervals along the arch-shaped outer surface of inner shell member 5. Each partition 19 is formed to extend from inner shell member 5 toward outer shell member 4, and a slight clearance is set between the tip of each partition 19 and the inner surface of outer shell member 4. This is to avoid impeding the elastic deformation of exterior body 1A when the above-mentioned external force is applied to exterior body 1A.

[0061] The material constituting the partition part 19 will be described. Since the partition part 19 may come into contact with the wire 2, it is preferable that the partition part 19 be made of the above-mentioned resin or foamed resin that is softer than the wire 2 in order to prevent or suppress wear of the wire 2 due to contact with the partition part 19.

[0062] The above-mentioned partitions 19 may be provided in the wiring space 12 in the exterior body 1 according to the first embodiment of the present invention. In addition, FIG. 10 shows an example in which the partitions 19 are provided at regular intervals along the arched outer surface of the inner shell member 5, but they may be provided at regular intervals along the arched inner surface of the outer shell member 4. Furthermore, in the example shown in FIG. 10, three partitions 19 are provided along the arched outer surface of the inner shell member 5, but the number is not particularly limited. Similarly, the plate thickness of the partitions 19 is not particularly limited. In short, it is sufficient that the partitions 19 are configured to divide the wiring space 12 and suppress the movement of the wires 2.

[0063] 10, the wiring space 12 is partitioned by the partitions 19, so that the movement of the wires 2 within the wiring space 12 can be suppressed and the position of the wires 2 can be substantially determined. As a result, wear and tear of the wires 2 due to the movement of the wires 2 within the wiring space 12 can be prevented or suppressed.

[0064] <Fifth embodiment> FIG. 11 is a cross-sectional view showing an example of an exterior body according to a fifth embodiment of the present invention. In the example shown in FIG. 11, instead of providing a partition portion 19 as a separate item for an exterior body 1A, a part of an inner shell member 5 is protruded toward an outer shell member 4 to form a partition portion 19A. Specifically, for example, an arch-shaped or elongated C-shaped or U-shaped cut extending in the axial direction is formed in a panel of the inner shell member 5. Then, the part surrounded by the cut is bent so as to protrude toward the outer shell member 4 to form the partition portion 19A. In the example shown in FIG. 11, three partition portions 19A are formed at predetermined intervals along the arch-shaped outer surface of the inner shell member 5. Also, a slight clearance is set between the tip of the partition portion 19A and the inner surface of the outer shell member 4, similar to the example shown in FIG. 10.

[0065] Therefore, even in the exterior body 1A having the configuration shown in FIG. 11, the partition portion 19A can partition the wiring space 12, so that the movement of the wire 2 in the wiring space 12 can be suppressed and the arrangement position of the wire 2 can be substantially determined. As a result, similar to the example shown in FIG. 10, wear of the wire 2 due to the movement of the wire 2 in the wiring space 12 can be prevented or suppressed. The partition portion 19A may be formed in the outer shell member 4. The partition portion 19A may also be formed in the inner shell member 5 or the outer shell member 4 of the exterior body 1 according to the first embodiment of the present invention or the exterior body 1B according to the third embodiment of the present invention. In short, the partition portion 19A may be configured to partition the wiring space 12 and suppress the movement of the wire 2.

[0066] Sixth embodiment FIG. 12 is a cross-sectional view showing an example of an exterior body according to a sixth embodiment of the present invention. The example shown in FIG. 12 is an example in which a cushion material 20 is provided as a movement suppressing part in the wiring space 12 in the exterior body 1A instead of the above-mentioned partition parts 19 and 19A. That is, the example shown here is an example configured to elastically deform the cushion material 20 to reduce the load (repulsive force) that the wire material 2 receives from the cushion material 20 when the wire material 2 comes into contact with the cushion material 20. The cushion material 20 is preferably made of a member or material softer than the wire material 2, such as the above-mentioned foamed resin, for example. In the example shown in FIG. 12, three cushion materials 20 are provided at predetermined intervals along the arch-shaped outer surface of the inner shell member 5. The cushion material 20 is attached to the outer surface of the inner shell member 5 by, for example, an adhesive or double-sided tape. On the other hand, the cushion material 20 is not particularly attached to the inner surface of the outer shell member 4, and is in a so-called free state. Therefore, when the above-mentioned external force is applied to the exterior body 1A, the cushion material 20 does not particularly hinder the elastic deformation of the exterior body 1A.

[0067] Therefore, even in the exterior body 1A having the configuration shown in Fig. 12, the wiring space 12 can be partitioned by the cushion material 20, so that the movement of the wire 2 in the wiring space 12 can be suppressed and the arrangement position of the wire 2 can be approximately determined. Also, wear of the wire 2 caused by the movement of the wire 2 in the wiring space 12 can be prevented or suppressed. Furthermore, when the wire 2 moves and contacts the cushion material 20, the wire 2 is pressed against the cushion material 20, causing the cushion material 20 to elastically deform. In other words, the wire 2 is not strongly pressed against the cushion material 20. Therefore, damage to the wire 2 can be more effectively prevented or suppressed.

[0068] Also, instead of the partitions 19, 19A and the cushioning material 20, an anti-slip material for the wire 2 may be provided in the wiring space 12. The anti-slip material may be a conventionally known tape or rubber, which can also prevent or suppress wear of the wire 2 caused by the movement of the wire 2 in the wiring space 12. Note that the anti-slip material is preferably made of the above-mentioned resin or foamed resin that is softer than the wire 2 in order to prevent or suppress damage and wear of the wire 2.

[0069] <Seventh embodiment> Furthermore, the exterior bodies 1, 1A, and 1B according to each embodiment may be configured to suppress movement of the inner shell member 5 relative to the attachment portion 3 arranged inside the inner shell member 5, for example, by a locking member. One example of the locking member is a cable tie. Fig. 13 shows one such example, and in the example shown in Fig. 13, the exterior body 1A attached to the attachment portion 3 is fixed to the attachment portion 3 by the cable tie. The cable tie 21 may be a conventionally known cable tie.

[0070] 13, if the exterior body 1A attached to the attachment portion 3 is restrained to the attachment portion 3 with a cable tie 21, the exterior body 1A can be more reliably fixed to the attachment portion 3. For example, it is possible to effectively prevent or suppress the exterior body 1A from falling off from the attachment portion 3 due to vibration of the vehicle. Note that instead of using the cable tie 21, the exterior body 1A may be tied to the attachment portion 3 with a rope or string. Note that the exterior body 1 according to the first embodiment of the present invention or the exterior body 1B according to the third embodiment of the present invention may be fixed to the attachment portion 3 with a cable tie 21.

[0071] <Eighth embodiment> The cable tie 21A may be formed integrally with the exterior body 1A. FIG. 14 shows an example. An inner shell member 5 will be described as an example. As shown in FIG. 14, a strip-shaped band portion 22 is formed integrally with the center of the other edge portion 11 of the inner shell member 5 in the direction of the central axis C of the exterior body 1A, and a plurality of sawtooth-shaped engagement pieces are formed at regular intervals on both sides in the width direction of the band portion 22. In addition, a locking portion 23 having large and small openings penetrating the inner shell member 5 in the plate thickness direction is formed on one edge portion 10 side of the inner shell member 5. Among the openings of the locking portion 23, a first opening 24 is formed slightly larger than the outer shape of the band portion 22 so that the band portion 22 can be inserted. Among the openings of the locking portion 23, a second opening 25 is formed in communication with the first opening 24 and has an opening width narrower than that of the first opening 24. Specifically, the opening width of second opening 25 in the direction of central axis C is set to be slightly wider than the width of the base portion of the engagement piece of band portion 22. Similarly, band portion 22 and locking portion 23 are formed in outer shell member 4. Then, exterior body 1A is produced as described above. At this time, each band portion 22 and each locking portion 23 of inner shell member 5 and outer shell member 4 are overlapped with each other and integrated.

[0072] A method of fixing the exterior body 1A by the cable tie 21A shown in FIG. 14, and its action and effect will be described. With the exterior body 1A attached to the attachment portion 3, the band portion 22 is passed through the first opening 24 of the locking portion 23 from the inner shell member 5 side toward the outer shell member 4 side. Also, the inner surface of the inner shell member 5 is brought into close contact with the attachment portion 3. Next, the band portion 22 is moved from the first opening 24 to the second opening 25. As a result, the base portion of the engagement piece is placed in or fitted into the second opening 25. As a result, the jaw portion of the engagement piece comes into contact with the outer surface of the outer shell member 4. In other words, when a load in a direction to pull out the band portion 22 from the second opening 25 acts on the exterior body 1A, the jaw portion of the engagement piece gets caught on the outer surface of the outer shell member 4. Therefore, it is possible to prevent or suppress the exterior body 1A from falling off from the attachment portion 3 due to the vibration of the vehicle. In this way, even with the exterior body 1A configured as shown in FIG. 14, it is possible to obtain almost the same action and effect as the configuration shown in FIG. 13. Note that a cable tie 21A shown in FIG. 14 may be integrally formed with the exterior housing 1 according to the first embodiment of the present invention or the exterior housing 1B according to the third embodiment of the present invention.
