[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.
[0030] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.
[0032] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.
[0033] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0034] This application provides a vehicle embodiment. It should be noted that the vehicle in this application can refer to large vehicles, small vehicles, special-purpose vehicles, etc. For example, according to vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles. For vehicles, as vehicle functions increase, the routing of wiring harnesses becomes increasingly complex, and the layout space becomes increasingly limited. Some wiring harnesses can only be laid overlappingly within a limited space. When the wiring harness exits, multiple wiring harnesses cross, causing mutual interference between them.
[0035] Therefore, this application provides a wire harness fixing bracket 20 for fixing wire harnesses. The wire harness includes a first wire harness and a second wire harness, and may also include a third wire harness, a fourth wire harness, and so on, multiple wire harnesses.
[0036] The wire harness fixing bracket 20 includes a first groove 21 and a second groove 22, both of which are along a first direction (see attached diagram). Figure 1 Extending in the X direction, the wire harness fixing bracket 20 has a first region 23 and a second region 24 connected in the first direction, with the first region 23 located on one side of the second region 24 in the first direction. In the first region 23, the first groove 21 and the second groove 22 extend along the second direction (see attached diagram). Figure 1 Arranged in the Y direction, in the second region 24, the first tank 21 and the second tank 22 are along the third direction (see Appendix). Figure 1 The Z-direction is superimposed, and the first direction, the second direction, and the third direction are perpendicular to each other.
[0037] At the junction of the first region 23 and the second region 24, the first groove 21 located in the first region 23 extends to a third direction, such that in the second region 24, the first groove 21 is located to a third direction of the second groove 22.
[0038] For example, for a vehicle, the first direction can be the front-to-back direction, the second direction can be the left-to-right direction, and the third direction can be the up-and-down direction. The wiring harness fixing bracket 20 extends in the front-to-back direction, the first groove 21 and the second groove 22 located in the first region 23 are arranged in the left-to-right direction, and the first groove 21 and the second groove 22 located in the second region 24 are stacked in the up-and-down direction.
[0039] The first wire harness is located in the first groove 21, which can protect and contain the first wire harness and guide the wiring direction of the first wire harness. The second wire harness is located in the second groove 22, which can protect and contain the second wire harness and guide the wiring direction of the second wire harness.
[0040] The first and second wire harnesses have opposite input directions and output directions. The first wire harness input direction is opposite to the first wire harness output direction, and the second wire harness input direction is opposite to the second wire harness output direction. The first and second wire harnesses cross-fold when exiting, while the output end of the wire harness fixing bracket 20 has overlapping openings along a third direction, which can avoid the first and second wire harnesses crossing-fold when exiting, thus avoiding interference between the first and second wire harnesses.
[0041] For example, the first groove 21 and the second groove 22 located in the first region 23 are arranged in the left-right direction, and the first groove 21 and the second groove 22 located in the second region 24 are stacked in the up-down direction. The first wire harness enters from the left and exits from the right; the second wire harness enters from the right and exits from the left. The exit end of the wire harness fixing bracket 20 has overlapping openings in the up-down direction, which avoids the first wire harness and the second wire harness crossing and folding when exiting.
[0042] The wire harness fixing bracket 20 provided in this application embodiment has a first region 23 and a second region 24 connected in a first direction. In the first region 23, the first groove 21 and the second groove 22 are arranged along the second direction. In the second region 24, the first groove 21 and the second groove 22 are stacked along the third direction. This can prevent the first wire harness and the second wire harness from crossing and folding when they exit, and avoid interference between the first wire harness and the second wire harness.
[0043] Reference Figures 1-2 In one possible implementation of this application, the first groove 21 and the second groove 22 of the first region 23 are arranged along a second direction, and the first groove 21 and the second groove 22 of the second region 24 are arranged along a third direction. In terms of manufacturing process, the arrangement of the first groove 21 and the second groove 22 along the second direction facilitates processing, while the arrangement of the first groove 21 and the second groove 22 along the third direction is more difficult to process and shape compared to the arrangement along the second direction. In the first direction, the length of the first region 23 is greater than the length of the second region 24, which facilitates the processing and shaping of the wire harness fixing bracket 20.
[0044] Reference Figures 1-6 In one possible implementation of this application, in the second region 24, the first tank 21 and the second tank 22 respectively have a first outlet 211 and a second outlet 221 disposed opposite to the first region 23, and the first outlet 211 and the second outlet 221 are located on one side of the first direction.
[0045] In the second region 24, the end of the first groove 21 facing away from the first region 23 is bent toward the second direction, and the end of the second groove 22 facing away from the first region 23 is also bent toward the second direction, so that the first outlet 211 and the second outlet 221 are in opposite directions, which makes it easier for the first wire harness and the second wire harness to exit in opposite directions without causing cross-folding.
[0046] For example, when the end of the first groove 21 away from the first region 23 bends toward the second direction, it is a rounded transition, which can avoid stress concentration at the bend of the first groove 21; when the end of the second groove 22 away from the first region 23 bends toward the second direction, it is a rounded transition, which can avoid stress concentration at the bend of the second groove 22.
[0047] Reference Figures 1-6 In one possible implementation of this application, the wiring harness fixing bracket 20 is located on a third-direction side of the vehicle body 10, that is, the wiring harness fixing bracket 20 is located above the vehicle body 10, and the vehicle body 10 plays the role of installing and supporting the wiring harness fixing bracket 20.
[0048] The first groove 21 has a first opening 212 facing away from the vehicle body 10, and the second groove 22 has a second opening 222 facing the vehicle body 10. The wire harness fixing bracket 20 has a Z-shaped opening. The first wire harness can be arranged in the first groove 21 through the first opening 212, and the second wire harness can be arranged in the first groove 21 through the second opening 222. In the second region 24, the first opening 212 and the second opening 222 partially or completely overlap in the third-direction projection plane.
[0049] Before the wire harness fixing bracket 20 is installed on the vehicle body 10, the first opening 212 and the second opening 222 are not covered, which facilitates the installation of the first wire harness and the second wire harness into the first groove 21 and the second groove 22. After installation, the wire harness fixing bracket 20 can be fixed in the first groove 21 and the second groove 22 by using cable ties, and then the wire harness fixing bracket 20 can be fixed on the vehicle body 10.
[0050] Reference Figures 1-2 In one possible implementation of this application, the wire harness fixing bracket 20 further includes a first mounting bracket 25 and a second mounting bracket 26. The first mounting bracket 25 is connected to one side of the first groove 21 in a second direction and is located in the second region 24. The second mounting bracket 26 is connected to one side of the second groove 22 in a second direction and is located in the first region 23. The first mounting bracket 25 and the second mounting bracket 26 are spaced apart along the first direction, which can fix the wire harness fixing bracket 20 to the vehicle body 10 in both the second and first directions, thereby improving the structural strength of fixing the wire harness fixing bracket 20 to the vehicle body 10.
[0051] Both the first mounting bracket 25 and the second mounting bracket 26 are detachably connected to the vehicle body 10. When it is necessary to replace or repair the wiring harness and the wiring harness fixing bracket 20, the first mounting bracket 25 and the second mounting bracket 26 can be removed from the vehicle body 10, which facilitates the replacement or repair of the wiring harness fixing bracket 20. After removing the wiring harness fixing bracket 20, a large operating space can be provided for removing the wiring harness. At the same time, neither the first opening 212 nor the second opening 222 is blocked by the vehicle body 10, which facilitates the removal of the first wiring harness and the second wiring harness.
[0052] For example, the first mounting bracket 25 has a first mounting hole 251, and the body 10 has a first stud 131 opposite to the first mounting hole 251. The first stud 131 passes through the first mounting hole 251 and is screwed to the first nut. The second mounting bracket 26 has a second mounting hole 261, and the body 10 has a second stud opposite to the second mounting hole 261. The second stud passes through the second mounting hole 261 and is screwed to the second nut. This makes the installation and fixing method of the wire harness fixing bracket 20 simple.
[0053] Secondly, this application provides a vehicle, including: a wiring harness fixing bracket 20, which is fixed to the vehicle body 10.
[0054] The vehicle provided in this application embodiment has the same technical effect as the wiring harness fixing bracket 20 provided in any of the above-mentioned embodiments. That is, the wiring harness is fixed to the vehicle body 10 by the wiring harness fixing bracket 20, and the crossing and folding of the first wiring harness and the second wiring harness when they come out can be avoided, thus avoiding interference between the first wiring harness and the second wiring harness.
[0055] Reference Figures 1-3 In one possible implementation of this application, the vehicle body 10 includes a first mating surface 11, a second mating surface 12, and a third mating surface 13 connected in sequence. The first mating surface 11 and the second mating surface 12 are arranged at an angle to each other, and the second mating surface 12 and the third mating surface 13 are arranged at an angle to each other. The wiring harness fixing bracket 20 includes a fourth mating surface 213, a fifth mating surface 214, and a sixth mating surface 215 connected in sequence. The first mating surface 11 is mated to the fourth mating surface 213, the second mating surface 12 is mated to the fifth mating surface 214, and the third mating surface 13 is mated to the sixth mating surface 215.
[0056] The bonding is achieved by bonding the first bonding surface 11 with the fourth bonding surface 213, bonding the second bonding surface 12 with the fifth bonding surface 214, and bonding the third bonding surface 13 with the sixth bonding surface 215. This can increase the contact area between the wire harness fixing bracket 20 and the vehicle body 10, improve the support strength of the vehicle body 10 for the wire harness fixing bracket 20, and also increase the structural strength of the wire harness fixing bracket 20 itself.
[0057] The first bonding surface 11 and the second bonding surface 12 are set at an angle to each other, the second bonding surface 12 and the third bonding surface 13 are set at an angle to each other, the first bonding surface 11 is bonded to the fourth bonding surface 213, the second bonding surface 12 is bonded to the fifth bonding surface 214, and the third bonding surface 13 is bonded to the sixth bonding surface 215. The vehicle body 10 can support and fix the wire harness fixing bracket 20 in different directions to further increase the support and fixing strength of the vehicle body 10 for the wire harness fixing bracket 20.
[0058] Reference Figures 1-2 In one possible implementation of this application, the fourth mating surface 213, the fifth mating surface 214 and the sixth mating surface 215 are jointly constructed as the bottom wall of the first groove 21, and the first groove 21 directly contacts the vehicle body 10, which simplifies the structure of the wire harness fixing bracket 20.
[0059] Reference Figures 1-2 In one possible implementation of this application, the included angle between the fourth mating surface 213 and the fifth mating surface 214 is an obtuse angle, and the included angle between the fifth mating surface 214 and the sixth mating surface 215 is an obtuse angle, so that the bottom wall of the first groove 21 bends more gently in the first direction, which can avoid stress concentration; at the same time, it also makes the routing of the first wire harness in the first groove 21 more gentle.
[0060] For example, the bottom wall of the second groove 22 also includes a first extension surface 223, a second extension surface 224 and a third extension surface 225 connected in sequence in the first direction, and the included angle between the first extension surface 223 and the second extension surface 224 is an obtuse angle, and the included angle between the second extension surface 224 and the third extension surface 225 is an obtuse angle, so that the bottom wall of the second groove 22 bends more gently in the first direction, which can avoid stress concentration; at the same time, it also makes the routing of the second wire harness in the second groove 22 more gentle.
[0061] Reference Figures 1-2 In one possible implementation of this application, the fourth mating surface 213 and the fifth mating surface 214 are connected by an arc transition, and the fifth mating surface 214 and the sixth mating surface 215 are connected by an arc transition. This can avoid stress concentration on the bottom wall of the first groove 21 and also facilitate the processing and manufacturing of the bottom wall of the first groove 21.
[0062] For example, the transition between the first extension surface 223 and the second extension surface 224 is an arc, and the transition between the second extension surface 224 and the third extension surface 225 is an arc. This can avoid stress concentration on the bottom wall of the second tank 22 and also facilitate the processing and manufacturing of the bottom wall of the second tank 22.
[0063] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
