Description

[Technical Field]

[0001] The present invention relates to a bracket for routing a plurality of pipes and wires within a frame, such as a truck frame. [Background technology]

[0002] In vehicles equipped with a ladder frame, such as trucks, piping and wiring may be installed inside the frame (for example, inside the side rails that make up the ladder frame). In this case, one fixing method involves fixing a bracket having a support part extending in the direction of the routing of the piping and wiring to the frame, and then fixing the piping and wiring to the bracket with a band while routing the piping and wiring along the support part of the bracket (see Patent Document 1).

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-94623 Summary of the Invention [Problem to be solved by the invention]

[0004] Recently, the number of pipes and wires in vehicles has increased, and these are sometimes bundled together and fixed to brackets. However, such a large bundle makes it difficult to manage the relative positions of the individual pipes and wires within the bundle. For example, depending on the front-to-back layout of the pipes and wires, they may cross each other or move from the back to the front, making the length and clearance from the surrounding area unstable.

[0005] Furthermore, if the bundle of pipes and wires becomes too thick to easily fit within the flange width of the side rail, there is a risk that it may come into close proximity to the U-bolts attached to the side rails during installation, or the crush stoppers attached to prevent deformation of the side rails when the U-bolts are fastened, and depending on assembly variations, there is a risk of interference with these.

[0006] This invention was invented with an eye on such issues, and one of its objectives is to provide a bracket for routing within a frame, which allows a large number of pipes and wires to be routed neatly within the frame, while avoiding the risk of interference with other components installed around the frame. [Means for solving the problem]

[0007] The present invention has been made to solve at least part of the above problems, and can be realized as the following aspects or application examples. The in-frame wiring bracket according to this application example is an in-frame wiring bracket for routing and fixing piping and wiring inside the frame of a vehicle, and comprises a base portion extending in a first direction, a mounting portion provided on the base portion and attached to the frame, and a plurality of support portions extending from the base portion in a second direction intersecting the first direction and supporting the piping and wiring, the support portions having narrowed portions at both ends in the second direction for wrapping and fixing fixing bands for the piping and wiring, and are oriented so that the second direction is along the longitudinal direction of the frame, and are fixed to the frame.

[0008] According to this application example, by utilizing the multiple support portions provided on one in-frame wiring bracket, multiple bundles of piping and wiring can be routed and fixed parallel to each other along the longitudinal direction of the frame. Therefore, the inside of the frame can be used evenly in the width direction (the direction perpendicular to the longitudinal direction), and multiple bundles of piping and wiring can be arranged and fixed at appropriate intervals. This achieves effects such as improved installation quality of piping and wiring and improved assembly without increasing the number of brackets (i.e., suppressing an increase in the number of parts). [Effects of the Invention]

[0009] According to this invention, a large number of pipes and wires can be arranged neatly within the frame, and the risk of interference with other members mounted around the frame can be avoided. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0011] The following embodiments will be described with reference to the drawings. The following embodiments are merely examples, and are not intended to exclude various modifications or applications of techniques not explicitly described in the embodiments. The configurations of the following embodiments can be modified in various ways without departing from the spirit of the invention. Furthermore, they can be selected or combined as needed.

[0012] The vehicle according to the present invention is a vehicle equipped with a frame, and the vehicle according to the present embodiment is a truck. In the present embodiment, an example will be described in which piping and wiring are routed and fixed to side rails that constitute the frame (ladder frame). While the term "piping and wiring" refers to both piping and wiring, it may refer to only piping or only wiring.

[0013] [1. Configuration] 2 and 3, the in-frame wiring bracket (hereinafter simply referred to as "bracket") 1 is used to route and fix piping and wiring 3 inside a vehicle frame 2. As shown in FIGS. 1(a) to 1(c), the bracket 1 includes a base portion 11 extending in a first direction A1, a mounting portion 12 provided on the base portion 11 and mounted on the frame 2, and a plurality of support portions 13, 14, and 15 extending from the base portion 11 and supporting a bundle 3A of piping and wiring 3. The first direction A1 corresponds to, for example, the vertical direction of the vehicle.

[0014] In this embodiment, the side rail 21 that constitutes the frame 2 has a channel-shaped cross section with a web 22 and flanges 23, 24 that are bent in one direction from both edges of the web, and the bracket 1 is attached to the inner surface of the web 22 of the side rail 21 (the surface on the side where the flanges protrude).

[0015] The first direction A1 in which the base portion 11 extends is the vertical direction in Figure 1(a), and when the bracket 1 is attached to the inner surface of the web 22 of the side rail 21, it coincides with the web width direction of the web 22 of the side rail 21 (a direction perpendicular to the longitudinal direction of the web 22, which in this case corresponds to the vertical direction of the vehicle). 1(a), the base portion 11 is formed in a strip shape (or a band shape) extending in the first direction A1 when viewed from the front. However, the base portion 11 is not limited to a strip shape as long as it extends in a predetermined direction.

[0016] The mounting portion 12 is provided at the middle in the first direction A1 of the base portion 11. As shown in Fig. 1(c), the mounting portion 12 is provided by projecting from a part of the base portion 11 on its back surface (the surface facing the web 22 when mounted), and as shown in Fig. 1(a), a bolt hole 12a is drilled in the center of the mounting portion 12 when viewed from the front.

[0017] 1(a), the support portions 13, 14, and 15 extend from one edge and the other edge of the base portion 11 at respective positions in the first direction A1 of the base portion 11 toward a second direction A2 (e.g., corresponding to the vertical direction of the vehicle) that intersects with the first direction A1. In this embodiment, the second direction A2 is a direction (the left-right direction in FIG. 1(a)) that is perpendicular to the first direction A1 and coincides with the longitudinal direction of the web 22 of the side rail 21 when the bracket 1 is attached. In other words, the bracket 1 is oriented so that the second direction A2 is along the longitudinal direction of the frame 2, and is fixed to the frame 2.

[0018] Here, three support parts are provided: a first support part 13 extending from both edges of the base part 11 (left and right in Figure 1(a)) at one end side of the base part 11; a second support part 14 extending from both edges of the base part 11 just at the other end side of the mounting part 12 of the base part 11; and a third support part 15 extending from both edges of the base part 11 just at the other end side of the second support part 14.

[0019] Therefore, the base portion 11 is provided with a first support portion 13, an attachment portion 12, a second support portion 14, and a third support portion 15 in this order from one end side (upper in FIG. 1(a)) to the other end side (lower in FIG. 1(a)). In this way, bead-shaped reinforcing structures 11a and 11b extending along the first direction A1 are provided on the back surface of the base portion 11, which extends from the attachment portion 12 in one and the other directions in the first direction A1 and supports the support portions 13, 14, and 15.

[0020] Each support portion 13, 14, 15 has the same configuration and includes a support surface 13a, 14a, 15a on its front surface (front surface in FIG. 1(a)) against which the bundle 3A of piping and wiring 3 abuts. The support surfaces 13a, 14a, 15a are formed to include the front surface of the base portion 11 between each support portion 13, 14, 15 spaced apart in the first direction A1. Each support portion 13, 14, 15 also has constricted portions 13b, 14b, 15b at both ends in the second direction A2 for wrapping and fixing a fixing band 30. As shown in FIG. 1(a), the constricted portions 13b, 14b, 15b are formed by cutting out both ends of each support portion 13, 14, 15 so that the width (length in the first direction A1) is partially narrowed.

[0021] The distal ends of the constricted portions 13b, 14b, and 15b are wider than the constricted portions 13b, 14b, and 15b, and function as retainers 13c, 14c, and 15c for the fixing band 30. As shown in FIG. 1(b), the distal ends of the retainers 13c, 14c, and 15c are curved toward the rear surface (the web 22 side when attached). This prevents the distal ends of the retainers 13c, 14c, and 15c from contacting and damaging the bundle 3A of piping and wiring 3 during and after attachment of the bundle 3A.

[0022] Furthermore, as shown in Figure 1(a), the bracket 1 has the mounting portion 12 positioned at a position offset from the center in the first direction A1 (a position offset upward in Figure 1(a)), so that it is asymmetrical about the mounting portion 12 in the first direction A1, but is formed symmetrically (bilaterally symmetrical) in the second direction A2, and each support portion 13, 14, 15 is arranged at approximately equal intervals.

[0023] The bracket 1 according to this embodiment is formed by pressing a metal plate, and both the mounting portion 12 and the bead-shaped reinforcing structures 11a and 11b are formed by bending a steel metal plate. Therefore, the bracket 1 is relatively lightweight and the manufacturing cost is kept low, but the mounting portion 12 and the reinforcing structures 11a and 11b may be formed by molding to have a thickness. Furthermore, the material is not limited to metal.

[0024] [3. Actions and Effects] Since the bracket 1 for wiring in a frame according to this embodiment is configured as described above, it is possible to obtain the following actions and effects.

[0025] First, to use the bracket 1, as shown in Figures 2 and 3, the mounting portion 12 of the bracket 1 is fastened with fasteners 26 such as bolts and nuts through bolt holes 25 drilled in the web 22 of the side rail 21, thereby fixing the bracket 1 to the web 22. This allows the bundle 3A of piping and wiring 3 to be routed and fixed by aligning it with each support surface 13a, 14a, 15a of each support portion 13, 14, 15 and wrapping and fixing a fixing band 30 around it using the constricted portions 13b, 14b, 15b.

[0026] In this way, by utilizing the multiple support parts 13, 14, 15 provided on one bracket 1 for wiring within a frame, multiple bundles 3A of piping and wiring 3 can be routed and fixed parallel to each other along the longitudinal direction of the frame 2. Therefore, the inside of the side rail 21 of the frame 2 can be used evenly in the web width direction of the web 22 (the vertical direction of the vehicle), and a plurality of bundles 3A can be arranged and fixed at appropriate intervals.

[0027] This allows for dividing and fixing a large bundle without increasing the number of brackets, thus suppressing an increase in the number of parts, and therefore improving the ease of mounting without increasing the bulk in the frame width direction. This has the effect of improving the installation quality of the piping and wiring 3 and improving assembly. It also leads to a reduction in assembly variations in the position within the bundle.

[0028] Furthermore, because the bundle of piping and wiring 3A does not become thick, it is easier to fit the bundle of piping and wiring 3A within the width of the flanges 23, 24 of the side rail 21. As shown by the area in Figure 3, a space SP is secured within the side rail 21, which prevents the bundle of piping and wiring 3A from coming into close proximity with the U-bolts attached to the side rails during installation and the crush stoppers attached to prevent deformation of the side rails when the U-bolts are fastened. This also prevents the bundle of piping and wiring 3A from interfering with these elements due to variations in assembly.

[0029] Furthermore, since the number of brackets 1 is reduced, there is also the effect that the positions of holes to be formed in the frame 2 (web 22 of side rail 21) for attaching the brackets 1 can be simplified. Furthermore, as described above, the bracket 1 is asymmetric in the first direction A1 but symmetric in the second direction A2, and each support portion 13, 14, 15 is arranged at approximately equal intervals. Therefore, when the bracket 1 is rotated 180 degrees from the use state shown in Figure 4(a) to the state shown in Figure 4(b) and turned upside down, the mounting portion 12 and each support portion 13, 14, 15 are in an upside-down position, and the bundle 3A can be similarly arranged and fixed while changing the upside-down position of the mounting portion 12. This improves the degree of freedom in selecting the positions of the bolt holes 25 formed in the frame 2.

[0030] [4. Other] The configuration of the above embodiment is merely an example, and can be appropriately modified and implemented without departing from the spirit of the present invention. For example, in the above embodiment, an example in which three support portions 13, 14, and 15 are provided has been described, but the number of support portions is not limited and may be two or four or more. In addition, the position of attachment portion 12 of bracket 1 is not limited and may be the center in the first direction. [Explanation of symbols]
