Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in recent years, the amount of piping and wiring in vehicles has increased, and in some cases, these are bundled thickly and fixed to brackets. However, when bundled thickly like this, it becomes difficult to manage the positional relationship of each piping and wiring within the bundle. For this reason, for example, depending on the layout before and after the routing location of the piping and wiring assemblies, they may cross each other or come from the back to the front, and the length and the gap with the surroundings become unstable.

[0005] Therefore, it is conceivable to route the piping and wiring assemblies by dividing them into a plurality of bundles. For example, Figure 4 shows a case where two bundles 3A of piping and wiring 3 are arranged vertically inside the frame 2 (inside the side rail 21). Each bundle 3A is fixed to a bracket 101, whose base end is attached to the inner wall surface of the frame 2 (the inner wall surface 22W of the web 22 of the side rail 21), using clips 31 and fixing bands 30. In this case, the cross-sectional space in the flange width direction (the direction in which flanges 23 and 24 protrude from the web 22) is reduced, but each bundle 3A must be arranged with a certain amount of vertical separation to prevent interference between adjacent bundles 3A and clips 31, etc. Therefore, the cross-sectional space inside the frame 2 required to arrange the two bundles 3A of piping and wiring 3, including mounting members such as brackets 101, clips 31 and fixing bands 30, becomes larger in the vertical direction, as shown by the dashed line in the figure. Also, a bracket 101 is required for each bundle 3A.

[0006] As a countermeasure, a bracket 102 capable of fixing two bundles 3A of piping and wiring 3 can be considered, as shown in Figure 5. Similar to the bracket 101 shown in Figure 4, the base end of this bracket 102 can be attached to the inner wall surface 22W of the web 22 of the side rail 21, but it protrudes more from the inner wall surface 22W of the web 22 in the flange width direction (the direction in which flanges 23 and 24 protrude from the web 22) than the bracket 101 shown in Figure 4, allowing two bundles 3A of piping and wiring 3 to be placed side by side. For this reason, clip holes 103 and 104 for fitting two clips 31 are provided at locations close to the web 22 and at locations further away from the web 22. By inserting the clip 31 upward into one clip hole 103 and downward into the other clip hole 104, the cross-sectional space inside the frame 2 required for the two bundles 3A, clips 31 and fixing bands 30 is reduced vertically while suppressing an increase in the protruding direction of the flanges 23 and 24.

[0007] However, the interior of the frame 2 (inside the side rail 21) is often used to accommodate more bundles of piping and wiring 3A and other on-board equipment. The smaller the cross-sectional space inside the frame 2 required to route the bundles of piping and wiring 3A, including mounting components, the more free space there is inside the frame 2, making it easier to mount a large number of piping and wiring 3 and other on-board equipment. In the configuration shown in Figure 5, although a large space can be secured at the bottom of the frame 2, the bundles of piping and wiring 3A do not fit inside the frame 2 (within the flange width of the side rail 21). In such cases, or even if they fit but with little room to spare, there is a risk of proximity to U-bolts attached to the side rails when mounting equipment to the vehicle, or to crush stoppers installed to prevent deformation of the side rails when fastening U-bolts, and depending on assembly variations, there is a risk of interference with these.

[0008] This invention was conceived in response to these challenges, and one of its objectives is to provide a bracket for internal routing within a frame that allows for the efficient and space-saving routing of numerous pipes and wires within the frame, thereby avoiding the risk of interference with other components mounted around the frame. [Means for solving the problem]

[0009] This project was undertaken to solve at least some of the above-mentioned problems and can be implemented in the following forms or applications. The bracket for routing wiring within a frame according to this application example is a bracket for routing and fixing piping and wiring inside the frame of a vehicle, wherein the frame has a U-shaped cross-section consisting of a web and flanges formed by bending from both the upper and lower edges of the web and projecting horizontally, and extends horizontally along the vehicle, and the bracket for routing wiring within a frame has a mounting portion attached to the mounting surface on the inside of the web of the frame, an arm portion projecting from the mounting portion toward the opening side of the frame, and at the end of the arm portion, opposite each other in the longitudinal direction of the frame The device comprises a first support portion and a second support portion, each positioned at a distance from the other, and each supporting the bundle of piping and wiring. The first support portion has a fixing surface with clip holes for securing the bundle of piping and wiring with fixing bands and clips, and has a first fixing surface facing one direction in the vertical direction. The second support portion has a fixing surface with clip holes for securing the bundle of piping and wiring with fixing bands and clips, and has a second fixing surface facing the other direction in the vertical direction. The second fixing surface is positioned vertically at a predetermined distance from the first fixing surface in the other direction.

[0010] According to this application example, two bundles of piping and wiring can be routed and fixed along the longitudinal direction of the frame by utilizing the first and second support parts provided on a single internal routing bracket for the frame. Furthermore, since the first fixing surface of the first support part faces one direction in the vertical direction, and the second fixing surface of the second support part faces the other direction in the vertical direction, the bundles of pipes and wiring can be fixed by attaching fixing bands and clips to one side of the first fixing surface (for example, the upper side) and fixing bands and clips to the other side of the second fixing surface (for example, the lower side), thereby fixing the bundles of pipes and wiring without them interfering with each other. Furthermore, since the second fixing surface is positioned at a predetermined distance away from the first fixing surface in the opposite direction, the cross-sectional space inside the frame required for arranging the bundle of pipes and wiring can be reduced vertically, while preventing the tip of the clip inserted into the clip hole from interfering with the bundle of pipes and wiring. Furthermore, since the first and second support parts are positioned spaced apart from each other in the longitudinal direction of the frame, these support parts can be positioned close to the web inside the frame without interfering with each other, and the cross-sectional space inside the frame required for routing bundles of piping and wiring can be reduced in the flange width direction of the frame (the direction in which the flange protrudes from the web). Therefore, a large number of pipes and wires can be efficiently arranged within the frame using fewer brackets, and the risk of interference with other components mounted around the frame can be avoided. [Effects of the Invention]

[0011] According to this method, a large number of pipes and wires can be efficiently arranged within the frame using fewer brackets, and the risk of interference with other components mounted around the frame can be avoided. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0013] The embodiments of this invention will be described with reference to the drawings. The following embodiments are merely illustrative examples, and there is no intention to exclude various modifications or applications of techniques not explicitly shown in these embodiments. Each configuration of the embodiments described below can be modified in various ways without departing from their spirit. Furthermore, they can be selected or combined as needed.

[0014] The vehicle in question is a vehicle equipped with a frame, and the vehicle according to this embodiment is a truck. In this embodiment, an example is described in which piping and wiring are routed and fixed to the side rails that constitute the frame (ladder frame). Note that piping and wiring refer to both pipes and wiring, but it may also refer to pipes only or wiring only. Furthermore, in Figures 1 to 3, which are referenced in the following description of embodiments, and in Figures 4 and 5, which are referenced as comparative examples, the vehicle is assumed to be on a horizontal plane, and the vehicle's longitudinal direction, horizontal direction, and vertical direction (vehicle's up-down direction) are defined, with the front of the vehicle designated as "FR", the rear of the vehicle as "RR", the right side in the vehicle width direction as "RH", the left side in the vehicle width direction as "LH", the vertically upward direction as "UP", and the vertically downward direction as "DW", indicated by arrows.

[0015] [1. First Embodiment] [1.1. Structure] As shown in Figure 1, the side rail 21 that constitutes the vehicle frame 2 consists of a web 22 and flanges 23 and 24 that are bent from both the upper and lower edges of the web 22 and project horizontally, and has a U-shaped cross-section, extending horizontally in the longitudinal direction of the vehicle. An opening 25 is formed between the two ends of the flanges 23 and 24, and the interior of the frame 2 (side rail 21) enclosed by the web 22 and flanges 23 and 24 can be accessed through this opening 25.

[0016] The bracket 1 for internal layout (hereinafter also simply abbreviated as "bracket") is for laying and fixing piping and wiring 3 inside the vehicle frame 2, and is attached to the mounting surface 22a inside the web 22 of the side rail 21 of the frame 2. As shown in FIGS. 1(a) and 1(b), the bracket 1 includes a mounting portion 11 attached to the mounting surface 22a inside the web 22 of the side rail 21, an arm portion 12 protruding from the upper edge portion of the mounting portion 11 toward the opening 25 side of the frame 2, and at the tip of the arm portion 12, a first support portion 13 and a second support portion 14 that are arranged at intervals from each other in the longitudinal direction (vehicle front-rear direction) of the frame 2 and both support the bundle 3A of the piping and wiring 3. Note that the arm portion 12 may protrude from the lower edge portion of the mounting portion 11 toward the opening 25 side of the frame 2.

[0017] The bracket 1 according to the present embodiment is formed by press-working sheet metal. The upper edge portion of the flat mounting portion 11 is bent at a right angle to form a flat arm portion 12, and at the tip of the arm portion 12, flat first support portion 13 and second support portion 14 are formed side by side in the longitudinal direction of the frame 2 (side rail 21). When the bracket 1 is attached, the flat surface of the mounting portion 11 is arranged in the vertical direction and the direction along the vehicle front-rear direction, similar to the flat surface of the web 22. Also, the flat surfaces of the arm portion 12, the first support portion 13, and the second support portion 14 are arranged in the horizontal direction.

[0018] In the present embodiment, the first support portion 13 utilizes an extension portion 12a obtained by directly extending the flat arm portion 12 toward the opening 25 side. The first support portion 13 has a fixing surface (first fixing surface) 13a with a clip hole 13b for fixing the bundle 3A of the piping and wiring 3 with a fixing band 30 and a clip 31. This fixing surface 13a faces vertically upward. The clip 31 is fixed to the clip hole 13b from above the fixing surface 13a, and the fixing band 30 locked to the clip 31 can fix the bundle 3A of the piping and wiring 3 above the fixing surface 13a.

[0019] On the other hand, in this embodiment, the second support portion 14 is positioned to be shifted one step lower than the first support portion 13 (extension portion 12a of the arm portion 12) in one direction (vehicle front-rear direction FR) of the longitudinal direction (vehicle front-rear direction) of the frame 2, via a stepped portion 15 having a step difference corresponding to a predetermined distance. The second support portion 14 also has a fixing surface (second fixing surface) 14a with clip holes 14b for fixing the bundle of piping and wiring 3A with fixing bands 30 and clips 31. This fixing surface 14a faces vertically downward, and the clips 31 can be fixed to the clip holes 14b from below the fixing surface 14a, and the bundle of piping and wiring 3A can be fixed below the fixing surface 14a with fixing bands 30 that are locked to the clips 31.

[0020] As described above, the first support portion 13 and the second support portion 14 are arranged spaced apart from each other in the longitudinal direction (vehicle front-rear direction) of the frame 2, and the bundle of piping and wiring 3A is fixed to the upper part of the first support portion 13, and the bundle of piping and wiring 3A is fixed to the lower part of the second support portion 14. As a result, the first support portion 13 and the second support portion 14 can be positioned at the same location in the flange width direction (the direction in which the flanges 23 and 24 protrude from both the upper and lower edges of the web 22, which in this embodiment is the same as the vehicle width direction) without interfering with each other. In this embodiment, as shown in Figure 1(a), the first support portion 13 and the second support portion 14 are positioned at the same location in the flange width direction.

[0021] Furthermore, as shown in Figure 1(b), the second fixing surface 14a is positioned vertically at a predetermined distance below the first fixing surface 13a. This arrangement is designed to prevent the tips of the clips 31 inserted into the clip holes 13b and 14b from interfering with the bundles 3A of pipes and wiring 3 adjacent to each other vertically. The predetermined distance is set from this perspective.

[0022] The clip 31 has a band locking portion 31a at its base end for locking the fixing band 30, an insertion portion 31b at its tip that is inserted into the clip holes 13b and 14b, and a contact portion 31c in the middle that is larger in diameter than the clip holes 13b and 14b and contacts the fixing surface 14a. The insertion portion 31b is formed so that its diameter gradually increases from the tip towards the base end, and in its natural state, the base end is larger in diameter than the clip holes 13b and 14b and is elastically deformable in the radial direction. As the insertion portion 31b enters the clip holes 13b and 14b, its base end undergoes elastic deformation, shrinking in diameter as it passes through the clip holes 13b and 14b. Once entry into the clip holes 13b and 14b is complete, it returns to its original shape and expands in diameter. As a result, the base end of the insertion portion 31b contacts the back surface of the fixing surface 14a. This contact, along with the contact portion 31c against the fixing surface 14a, secures the clip 31 to the clip hole 14b. Note that clips 31 and fixing bands 30 are also commonly used in an integrated form.

[0023] [1.2. Action and Effects] Since the bracket 1 for routing within the frame according to this embodiment is configured as described above, the following functions and effects can be obtained.

[0024] First, in order to use bracket 1, the mounting portion 11 of bracket 1 is fastened to the inner wall surface 22W of the web 22 of the side rail 21 using fasteners 27 such as bolts and nuts through bolt holes 26 drilled in the web 22 of the side rail 21, thereby fixing bracket 1 to the inner wall surface 22W of the web 22. Then, clips 31 are inserted into the clip holes 13b and 14b of the fixing surfaces 13a and 14a of each support part 13 and 14 to secure them, and bundles of piping and wiring 3A are positioned above the fixing surface 13a and below the fixing surface 14a, respectively, along the flow direction (vehicle front-rear direction) of the frame 2. The fixing bands 30, which are secured to each clip 31, are wrapped around the bundles of piping and wiring 3A to secure them, thereby allowing the bundles of piping and wiring 3A to be routed and fixed.

[0025] In this way, by utilizing the two support parts 13 and 14 provided on a single internal wiring bracket 1, multiple bundles 3A of piping and wiring 3 can be routed parallel to each other along the longitudinal direction of the frame 2 and fixed in place. Therefore, two sets of bundles 3A can be positioned and fixed at appropriate intervals within the side rails 21 of the frame 2, utilizing the space in the web width direction (vehicle vertical direction) of the web 22.

[0026] This allows for the division and fixing of the piping and wiring bundle 3A while keeping the number of brackets and parts to a minimum, thus reducing bulk in the frame width direction (flange width direction) and improving ease of installation. Consequently, it is possible to obtain effects such as improved installation quality and ease of assembly of the piping and wiring bundle 3. It also leads to a reduction in assembly variation in the position of the piping and wiring bundle 3 within the bundle 3A.

[0027] Furthermore, since the bundle of pipes and wiring 3A does not become thicker, it becomes easier to fit the bundle of pipes and wiring 3A within the width of the flanges 23 and 24 of the side rail 21. As a result, the cross-sectional space inside the frame 2 required to arrange the two bundles of pipes and wiring 3A is reduced both vertically and horizontally (in the direction of the frame width, or flange width), as shown by the dashed line in Figure 1(a), improving space efficiency. Consequently, as shown by the shaded area in Figure 1(a), a large empty space SP is secured within the side rail 21 both vertically and horizontally (in the direction of the frame width, or flange width). This empty space SP promotes space saving in the vertical direction compared to the configuration shown in Figure 4, for example, and significantly promotes space saving in the direction of the frame width (especially on the side of the opening 25) compared to the configuration shown in Figure 5, improving ease of installation.

[0028] In particular, when mounting equipment onto a vehicle, as shown in Figure 2(a) or Figure 2(b), U-bolts 40 are attached to the side rail 21, and crush guards 41 and 42 may be installed to suppress deformation of the opening 25 of the side rail 21 when the U-bolts 40 are fastened. However, since space SP is secured, the risk of the bundle of piping and wiring 3A coming into close proximity with the U-bolts 40 and crush guards 41 and 42 is avoided. In addition, the risk of the bundle of piping and wiring 3A interfering with these due to assembly variations is also avoided.

[0029] Furthermore, since two bundles of piping and wiring 3A can be fixed with a single bracket 1, the number of brackets 1 can be reduced, thus improving the ease of assembly related to the routing of piping and wiring 3. Furthermore, since the number of bolt holes 26 formed in the frame 2 (web 22 of the side rail 21) for attaching the bracket 1 can be reduced, the degree of freedom in selecting the position of the bolt holes 26 formed in the frame 2 is improved.

[0030] [2. Second Embodiment] [2.1. Structure] As shown in Figures 3(a) and 3(b), the bracket 5 according to this embodiment includes a mounting portion 51 attached to the mounting surface 22a on the inside of the web 22 of the side rail 21, an arm portion 52 protruding from the upper edge of the mounting portion 51 toward the opening 25 of the frame 2, and at the end of the arm portion 52, a first support portion 53 and a second support portion 54, which are spaced apart from each other in the longitudinal direction (vehicle front-rear direction) of the frame 2 and both support the bundle 3A of piping and wiring 3. The arm portion 52 may also protrude from the upper edge of the mounting portion 51 toward the opening 25 of the frame 2, as in the first embodiment.

[0031] The bracket 5 according to this embodiment is also formed by press-forming sheet metal. The lower edge of the flat mounting portion 11 is bent at a right angle to form a flat arm portion 52, and a flat first support portion 53 and a second support portion 54 are formed at the tip of the arm portion 52, aligned in the longitudinal direction of the frame 2 (side rail 21). When the bracket 1 is mounted, the flat surface of the mounting portion 51 is positioned vertically and along the front-rear direction of the vehicle, similar to the flat surface of the web 22. The flat surfaces of the arm portion 52, the first support portion 53 and the second support portion 54 are positioned horizontally.

[0032] In the first embodiment, the first support portion 13 utilizes an extension portion 12a that extends the flat plate-shaped arm portion 12 directly toward the opening 25. In contrast, the first support portion 53 in this embodiment is positioned to shift upward by one step from the extension portion 52a of the arm portion 52, via a stepped portion 56 that has a step in the direction other than the longitudinal direction (vehicle rear direction) of the frame 2 (vehicle rear direction RR). Similar to the first embodiment, the first support portion 53 has a fixing surface (first fixing surface) 53a with clip holes 53b for fixing the bundle of piping and wiring 3A with fixing bands 30 and clips 31. This fixing surface 53a also faces vertically upward, and the clips 31 can be fixed to the clip holes 53b from above the fixing surface 53a, and the bundle of piping and wiring 3A can be fixed above the fixing surface 53a with fixing bands 30 that are locked to the clips 31.

[0033] On the other hand, the second support portion 54 is positioned to shift down one step from the extension portion 52a of the arm portion 52 via a stepped portion 55 that has a step in one direction (vehicle front-rear direction FR) in the longitudinal direction (vehicle front-rear direction) of the frame 2. The second support portion 54 also has a fixing surface (second fixing surface) 54a with clip holes 54b for fixing the bundle of piping and wiring 3A with fixing bands 30 and clips 31, similar to the first embodiment. This fixing surface 54a faces vertically downward, and the clips 31 are fixed to the clip holes 54b from below the fixing surface 54a, and the bundle of piping and wiring 3A can be fixed below the fixing surface 54a with fixing bands 30 that are locked to the clips 31.

[0034] As described above, the first support portion 53 and the second support portion 54 are arranged spaced apart from each other in the longitudinal direction (vehicle front-rear direction) of the frame 2, and the bundle of piping and wiring 3A is fixed to the upper part of the first support portion 53, and the bundle of piping and wiring 3A is fixed to the lower part of the second support portion 54. As a result, the first support portion 53 and the second support portion 54 can be positioned at the same location in the flange width direction (the direction in which the flanges 23 and 24 protrude from both the upper and lower edges of the web 22, which in this embodiment is the same as the vehicle width direction) without interfering with each other. In this embodiment, as shown in Figure 3(a), the first support portion 53 and the second support portion 54 are positioned at the same location in the flange width direction.

[0035] Furthermore, as shown in Figure 3(b), the second fixing surface 54a is positioned vertically at a predetermined distance below the first fixing surface 53a. This arrangement, similar to that of the first embodiment, is designed to prevent the tips of the clips 31 inserted into the clip holes 53b and 54b from interfering with the bundles 3A of pipes and wiring 3 adjacent to each other vertically. The predetermined distance is set from this perspective.

[0036] [2.2. Action and Effects] Since the bracket 5 for routing within the frame according to this embodiment is configured as described above, the following functions and effects can be obtained.

[0037] Similar to the first embodiment, by fixing the bracket 5 to the inner wall surface 22W of the web 22 of the side rail 21, the clips 31 are inserted into the clip holes 53b and 54b of the fixing surfaces 53a and 54a of each support part 53 and 54 to secure them, and the bundles 3A of piping and wiring 3 are arranged above the fixing surface 53a and below the fixing surface 54a, respectively, along the flow direction (vehicle front-rear direction) of the frame 2, and the fixing bands 30 that are locked to each clip 31 are wrapped around the bundles 3A of piping and wiring 3 to secure them, thereby allowing the bundles 3A of piping and wiring 3 to be routed and secured.

[0038] In this way, similar to the first embodiment, multiple bundles 3A of piping and wiring 3 can be routed parallel to each other along the longitudinal direction of the frame 2 by utilizing two support parts 53 and 54 provided on one frame internal routing bracket 5. As a result, similar to the first embodiment, the number of brackets can be kept to a minimum, and the bundle 3A of piping and wiring 3 can be divided and fixed while keeping the number of parts to a minimum. This reduces bulk in the frame width direction (flange width direction), improves mounting efficiency, and results in improved installation quality and ease of assembly of the piping and wiring 3. It also leads to a reduction in assembly variation in the position of the piping and wiring 3 within the bundle 3A.

[0039] Furthermore, the bundle of piping and wiring 3A can be easily accommodated within the width of the flanges 23 and 24 of the side rail 21, and the cross-sectional space inside the frame 2 required to arrange the two bundles of piping and wiring 3A is reduced both vertically and horizontally (in the frame width direction, flange width direction), as shown by the dashed line in Figure 3(a), improving space efficiency. As a result, as shown by the shaded area in Figure 3(a), a large empty space SP is secured inside the side rail 21 both vertically and horizontally (in the frame width direction, flange width direction). This empty space SP promotes space saving in the vertical direction compared to the configuration shown in Figure 4, for example, and significantly promotes space saving in the frame width direction (especially on the opening 25 side) compared to the configuration shown in Figure 5, improving ease of installation. Similar to the first embodiment, since space SP is secured, the risk of the bundle of piping and wiring 3A coming into close proximity with the U-bolts 40 and crush stoppers 41 and 42 is avoided, and the risk of the bundle of piping and wiring 3A interfering with these due to assembly variations is also avoided.

[0040] Furthermore, similar to the first embodiment, two bundles 3A of piping and wiring 3 can be fixed with one bracket 1, and the number of brackets 1 can be reduced, thus improving the ease of assembly related to the routing of piping and wiring 3. Furthermore, since the number of bolt holes 26 formed in the frame 2 (web 22 of the side rail 21) for attaching the bracket 1 can be reduced, the degree of freedom in selecting the position of the bolt holes 26 formed in the frame 2 is improved.

[0041] [4. Others] The configurations of each of the embodiments described above are examples and can be modified as appropriate without departing from the spirit of the present invention. For example, in each of the embodiments described above, an example in which one bracket 1 is used was explained, but it is preferable to use multiple brackets 1 or 5 at appropriate spans along the longitudinal direction of the bundle 3A of piping and wiring 3, depending on the length of the bundle 3A of piping and wiring 3. Furthermore, although the above embodiments described examples of arranging two bundles 3A of piping and wiring 3, it is also possible to arrange more than two bundles 3A of piping and wiring 3 by using multiple brackets 1.
