Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a wiring harness fixing structure and a vehicle using the wiring harness fixing structure. Background Technology

[0002] In vehicles, wiring harnesses serve as the core transmission carrier of the electrical system, undertaking crucial functions in power distribution and signal transmission. In the complex layout of a vehicle, wiring harnesses must traverse dynamic areas such as sheet metal and hinges; their reliable fixation directly affects the durability of the wiring and driving safety. Especially for multi-branch wiring harnesses, precise path constraints can effectively prevent insulation wear or poor contact caused by vibration and displacement.

[0003] In related technologies, a wire harness clip is used to secure multiple wire harnesses. This clip is an integrated structure, wherein the base plate of the clip has multiple equally spaced locking holes, with one locking hole corresponding to one wire harness. During installation, multiple wire harnesses are pressed into the multiple locking holes one by one to secure them.

[0004] However, during use, the aforementioned wiring harness clips can cause adjacent wiring harnesses to become entangled and rub against each other, which can accelerate the rupture of the wiring harness insulation layer and cause a short circuit risk. This would reduce the safety of the wiring harness and, consequently, the safety of the vehicle. Utility Model Content

[0005] This application provides a wiring harness fixing structure and a vehicle, which can adjust the routing direction of the wiring harness to a certain extent to avoid the insulation layer of the wiring harness from cracking, thereby avoiding short circuits in the wiring harness and improving the safety of the wiring harness, thus improving the safety of the vehicle.

[0006] On the one hand, this application provides a wire harness fixing structure, including multiple wire clip assemblies spliced ​​together, each wire clip assembly having a wire through hole for the wire harness to pass through; wherein, two adjacent wire clip assemblies can rotate relative to each other to change the orientation of any wire through hole.

[0007] Firstly, the unidirectional locking hole layout of the integrated wiring harness clips in related technologies forces multiple wiring harnesses to extend in a parallel posture. Especially in dynamic areas of the vehicle (such as near door hinges and suspension systems), the wiring harness group is forced to undergo unidirectional collective displacement due to mechanical vibration or body deformation, resulting in adjacent wiring harnesses being in a state of frictional contact for a long time. In this application, however, through the splicing structure of independently rotatable wiring clip components, the orientation of each wire hole can be adjusted according to the actual routing requirements of the corresponding wiring harness, so that multiple wiring harnesses form a differentiated path distribution in space. For example, in areas of the vehicle body with complex steering, some wiring harnesses can be adjusted to go vertically around obstacles, while others remain horizontally extended, thereby eliminating parallel contact sections between wiring harnesses to a certain extent.

[0008] Secondly, the rigid fixing mode in related technologies causes the wire harness assembly to resonate under vibration and impact, exacerbating frictional losses between the wire harness and the keyhole edge. In contrast, the discretized wire clamp assembly of this application disperses the force on the overall wire harness assembly into local constraints of multiple independent units. The relative rotational capability between adjacent wire clamp assemblies can absorb some vibration energy, forming a buffering effect similar to a "flexible joint." This dynamic adaptability can not only reduce the amplitude of a single wire harness but also further reduce the probability of collisions between wire harnesses by changing the vibration phase difference between different wire harness segments.

[0009] Furthermore, the integrated clips in related technologies require the complete disassembly of the entire wiring harness before a single faulty harness can be replaced during maintenance. This process can easily cause secondary damage to other wiring harnesses due to pulling. The modular design in this application supports partial disassembly and assembly. Maintenance personnel only need to separate specific clip components to maintain the target wiring harness, while the remaining wiring harnesses remain fixed by adjacent clip components. This improves maintenance efficiency and, to some extent, avoids wiring harness displacement caused by large-scale disassembly, thereby extending the lifespan of the wiring harness.

[0010] As an optional implementation, the multiple line card assemblies include a first line card assembly and multiple second line card assemblies, with the multiple second line card assemblies sequentially spliced ​​together, and the first line card assembly spliced ​​to the ends of the multiple second line card assemblies; the first line card assembly includes two first wire clips, which are fastened together to form a wire through hole; the second line card assembly includes a first wire clip and a second wire clip, which are fastened together to form a wire through hole; in adjacent first and second line card assemblies, any first wire clip of the first line card assembly is connected to a second wire clip of the second line card assembly; in two adjacent second line card assemblies, the second wire clip of one second line card assembly is connected to the second wire clip of the other second line card assembly.

[0011] This allows each wire bundle to be individually threaded into its corresponding wire guide hole.

[0012] As an optional implementation, the first wire-clamping component includes a first wire-clamping body, which has a first end face and a second end face arranged opposite to each other. The first end face and the second end face are spaced apart along the splicing direction of the plurality of wire-clamping assemblies, and a first connecting hole is formed on the first end face. The second wire-clamping component includes a second wire-clamping body and a connecting post. The second wire-clamping body has a third end face and a fourth end face arranged opposite to each other. The third end face and the fourth end face are spaced apart along the splicing direction of the plurality of wire-clamping assemblies, and the connecting post is disposed on the third end face. The axial direction of the connecting post is consistent with the axial direction of the first connecting hole. In adjacent first and second wire-clamping assemblies, the connecting post of the second wire-clamping assembly extends into any of the first connecting holes of the first wire-clamping assembly and is connected with the first connecting hole. The connecting post is rotatable relative to the first connecting hole.

[0013] This allows the adjacent first and second line clip assemblies to rotate independently around the splicing axis, thereby flexibly adjusting the orientation of their respective wire holes.

[0014] As an optional implementation, a second connecting hole is provided on the fourth end face, and the axis of the second connecting hole is consistent with the axis of the connecting post; in two adjacent second line clamp assemblies, the connecting post of one second line clamp assembly extends into the second connecting hole of the other second line clamp assembly and is connected with the second connecting hole; wherein, the connecting post is rotatable relative to the second connecting hole.

[0015] This allows multiple second-line card assemblies to adjust the orientation of the wire holes step by step along the splicing chain.

[0016] As an optional implementation, the connecting post is a stud, and both the first connecting hole and the second connecting hole are threaded holes.

[0017] In this way, the axial preload generated by the thread engagement can effectively suppress the unexpected rotation of the first and second wire clamp assemblies under vibration, ensuring the reliability of the angle locking after the wire hole orientation is adjusted; at the same time, the progressive engagement characteristic of the threaded pair allows the operator to fine-tune the rotational damping between adjacent first and second wire clamp assemblies, or between two adjacent second wire clamp assemblies, by controlling the screw-in depth.

[0018] As an optional implementation, the first wire clamping body forms a first wire guide groove, and the second wire clamping body forms a second wire guide groove; in the first wire clamping assembly, the two first wire guide grooves are engaged together to form a wire guide hole, and the two first wire guide grooves have the same shape and equal size; in the second wire clamping assembly, the first wire guide groove and the second wire guide groove are engaged together to form a wire guide hole, and the first wire guide groove and the second wire guide groove have the same shape and equal size.

[0019] This design ensures that the inner wall contour of each wire hole remains uniformly closed, which to some extent avoids uneven local pressure on the wire harness caused by misalignment of the slot.

[0020] As an optional implementation, the first wire-clamping body has a first fastening hole that penetrates through the first wire-clamping body and is located on the side of the first wire-passing groove; the second wire-clamping body has a second fastening hole that penetrates through the second wire-clamping body and is located on the side of the second wire-passing groove; in each first wire-clamping assembly, the two first fastening holes are arranged opposite to each other, and the two first wire-clamping components are connected together by first fasteners passing through the two first fastening holes; in each second wire-clamping assembly, the first fastening hole and the second fastening hole are arranged opposite to each other, and the first wire-clamping component and the second wire-clamping component are connected together by second fasteners passing through the first fastening hole and the second fastening hole.

[0021] In this way, when the two first wire-clamping components are fastened together, the first fastener passes through from the side of the first wire-passing groove. When the first wire-clamping component and the second wire-clamping component are fastened together, the second fastener passes through from the side of the second wire-passing groove. This not only avoids interference with the wire harness's path through the wire-passing hole to a certain extent, but also ensures the tightness of the wire harness's wrapping around the inner wall of the wire-passing hole by applying balanced closing pressure through symmetrically distributed fastening points.

[0022] As an optional implementation, both the first fastening hole and the second fastening hole are threaded holes.

[0023] In this way, when the first or second fastener is screwed in, the progressive engagement of the threaded pair can generate an axial preload, forcing the two first wire clamping components or the first wire clamping component to fit tightly against the second wire clamping component. This can eliminate the assembly gap of the wire hole closing surface to a certain extent and enhance the radial clamping stability of the first or second wire clamping assembly on the wire harness.

[0024] As an optional implementation, the axial direction of the first fastening hole is perpendicular to the axial direction of the wire passage hole, and the axial direction of the second fastening hole is perpendicular to the axial direction of the wire passage hole.

[0025] In this way, when the first and second fasteners are screwed in, a locking force is applied perpendicular to the extension direction of the wire harness. This not only avoids axial compression deformation of the wire harness during the fastening operation to a certain extent, but also enhances the shear strength of the mating surfaces of the two first wire clamping components and the shear strength of the mating surfaces of the first and second wire clamping components through lateral constraint.

[0026] As an optional implementation, the wire harness fixing structure provided in this application includes three wire clip assemblies spliced ​​together.

[0027] This makes the wire harness fixing structure provided in this application applicable to the fixing of three-phase wires.

[0028] On the other hand, this application provides a vehicle including a frame, three-phase wires and the aforementioned wiring harness fixing structure; wherein each wire clip assembly is connected to the frame, and each wire harness in the three-phase wires is correspondingly passed through the wire hole of the wiring harness fixing structure.

[0029] The vehicle provided in this application has high safety and strong stability due to the use of the aforementioned wiring harness fixing structure. Attached Figure Description

Detailed Implementation

[0045] The technical solutions in this application will be clearly and thoroughly described below with reference to the accompanying drawings. In the description of the embodiments of this application, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in the text is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Furthermore, in the description of the embodiments of this application, "multiple" refers to two or more than two.

[0046] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0047] In vehicles, wiring harnesses serve as the core transmission carrier of the electrical system, undertaking the crucial functions of power distribution and signal transmission. In the complex layout of a vehicle, wiring harnesses need to pass through dynamic areas such as body panels and moving hinges, and their reliable fixation directly affects the durability of the wiring and driving safety.

[0048] In related technologies, a wire harness clip is used to secure multiple wire harnesses. This clip is an integrated structure, wherein the base plate of the clip has multiple equally spaced locking holes, with one locking hole corresponding to one wire harness. During installation, multiple wire harnesses are pressed into the multiple locking holes one by one to secure them.

[0049] However, during use, the aforementioned wiring harness clips can cause adjacent wiring harnesses to become entangled and rub against each other, which can accelerate the rupture of the wiring harness insulation layer and cause a short circuit risk. This would reduce the safety of the wiring harness and, consequently, the safety of the vehicle.

[0050] Based on this, embodiments of this application provide a wiring harness fixing structure and a vehicle, which can adjust the routing direction of a single wiring harness, thereby preventing adjacent wiring harnesses from tangling and rubbing against each other to a certain extent. This can also prevent the insulation layer of the wiring harness from cracking, thus preventing short circuits to a certain extent. In this way, the service life of the wiring harness can be extended and the safety of the wiring harness can be improved, thereby improving the safety of the vehicle.

[0051] The embodiments of this application will be described in detail below with reference to the accompanying drawings and specific implementation details.

[0052] Please combine Figures 1 to 4 , Figure 1 This is a schematic diagram of the wire harness fixing structure provided in an embodiment of this application. Figure 2 This is an exploded view of the wire harness fixing structure provided in an embodiment of this application. Figure 3 This is a diagram showing the usage state of the wire harness fixing structure provided in the embodiments of this application. Figure 4 for Figure 3 A schematic diagram of the structure from another perspective. As shown in the figure, this embodiment provides a wire harness fixing structure 10, including multiple wire clip assemblies 1 spliced ​​together. Each wire clip assembly 1 has a wire hole 11 for the wire harness 20 to pass through. Adjacent wire clip assemblies 1 can rotate relative to each other to change the orientation of any wire hole 11.

[0053] Firstly, the unidirectional locking hole layout of the integrated wiring harness clips in related technologies forces multiple wiring harnesses to extend in a parallel posture. Especially in dynamic areas of the vehicle (such as near door hinges and suspension systems), the wiring harness group is forced to undergo unidirectional collective displacement due to mechanical vibration or body deformation, resulting in adjacent wiring harnesses being in a state of frictional contact for a long time. In this embodiment, through the splicing structure of the independently rotatable wiring clip assembly 1, each wire hole 11 can adjust its orientation according to the actual routing requirements of the corresponding wiring harness 20, so that multiple wiring harnesses 20 form a differentiated path distribution in space. For example, in areas of the vehicle body with complex steering, some wiring harnesses 20 can be adjusted to go around obstacles vertically, while others remain horizontally extended, thereby eliminating parallel contact sections between wiring harnesses to a certain extent.

[0054] Secondly, the rigid fixing mode in related technologies causes the wire harness assembly to resonate under vibration and impact, exacerbating frictional losses between the wire harness and the keyhole edge. In contrast, the discrete wire clip assembly 1 in this embodiment disperses the force on the overall wire harness assembly into local constraints of multiple independent units. The relative rotational capability between adjacent wire clip assemblies 1 can absorb some vibration energy, forming a buffering effect similar to a "flexible joint". This dynamic adaptability can not only reduce the amplitude of a single wire harness, but also further reduce the probability of collision between wire harnesses by changing the vibration phase difference of each wire harness segment 20.

[0055] Furthermore, the integrated clips in related technologies require the complete disassembly of the entire wiring harness before a single faulty harness can be replaced during maintenance. This process can easily cause secondary damage to other wiring harnesses due to pulling. The modular design in this embodiment supports partial disassembly and assembly. Maintenance personnel only need to separate specific clip components to maintain the target wiring harness 20, while the remaining wiring harnesses 20 remain fixed by adjacent clip components 1. This improves maintenance efficiency and, to some extent, avoids positional displacement of the wiring harness 20 due to large-scale disassembly, thereby extending the service life of the wiring harness 20.

[0056] like Figure 3 and Figure 4 As shown, in some specific embodiments, the wire harness fixing structure 10 provided in this embodiment can be used to fix three-phase wires. That is, the wire harness fixing structure 10 in this embodiment includes three wire clip assemblies 1 spliced ​​together. In other words, the wire harness fixing structure 10 has three wire holes 11. The three-phase wires include U-phase wire 20A, V-phase wire 20B and W-phase wire 20C. Then, U-phase wire 20A is correspondingly inserted through a wire hole 11, V-phase wire 20B is correspondingly inserted through a wire hole 11, and W-phase wire 20C is correspondingly inserted through a wire hole 11.

[0057] Therefore, when the above-mentioned wiring harness fixing structure 10 is applied to a vehicle, the crossing between the wiring harnesses can be avoided to a certain extent when the three-phase wires of the motor and the three-phase wires of the electronic control are arranged in opposite directions.

[0058] In some embodiments, the plurality of line clip assemblies 1 include a first line clip assembly 1A and a plurality of second line clip assemblies 1B, the plurality of second line clip assemblies 1B being sequentially spliced ​​together, and the first line clip assembly 1A being spliced ​​to the ends of the plurality of second line clip assemblies 1B; the first line clip assembly 1A includes two first wire clips 12, the two first wire clips 12 being fastened together to form a wire through hole 11; the second line clip assembly 1B includes a first wire clip 12 and a second wire clip 13, the first wire clip 12 and the second wire clip 13 being fastened together to form a wire through hole 11; in adjacent first line clip assemblies 1A and second line clip assemblies 1B, any first wire clip 12 of the first line clip assembly 1A is connected to a second wire clip 13 of the second line clip assembly 1B; in two adjacent second line clip assemblies 1B, the second wire clip 13 of one second line clip assembly 1B is connected to the second wire clip 13 of the other second line clip assembly 1B.

[0059] The first wire clip assembly 1A forms a wire hole 11 by fastening two first wire clip pieces 12 together, serving as an end fixing unit; the multiple second wire clip assemblies 1B form an extended fixing chain in the middle section by fastening the first wire clip piece 12 and the second wire clip piece 13 together, so that each wire bundle 20 can be individually inserted into the corresponding wire hole 11.

[0060] Specifically, since the orientation of each wire hole 11 is independently adjustable, the U-phase wire 20A, V-phase wire 20B, and W-phase wire 20C can extend in different directions respectively.

[0061] Please continue to combine Figures 5 to 7 , Figure 5 This is a three-dimensional structural diagram of the first wire clamp in the wire harness fixing structure provided in the embodiments of this application. Figure 6 for Figure 5 A schematic diagram of the three-dimensional structure from another perspective. Figure 7 for Figure 5 A three-dimensional structural schematic diagram from another perspective. As shown in the figure, in some embodiments, the first wire-clamping component 12 includes a first wire-clamping body 121. The first wire-clamping body 121 has a first end face 1211 and a second end face 1212 arranged opposite to each other. The first end face 1211 and the second end face 1212 are spaced apart along the splicing direction of the plurality of wire-clamping components 1. A first connecting hole 1213 is provided on the first end face 1211.

[0062] Furthermore, please combine Figures 8 to 10 , Figure 8 This is a three-dimensional structural diagram of the second wire clamp in the wire harness fixing structure provided in the embodiments of this application. Figure 9 for Figure 8 A schematic diagram of the three-dimensional structure from another perspective. Figure 10 for Figure 8 A three-dimensional structural diagram from another perspective. The structure of the second wire clip 13 can be described as follows: the second wire clip 13 includes a second wire clip body 131 and a connecting post 132. The second wire clip body 131 has a third end face 1311 and a fourth end face 1312 arranged opposite to each other. The third end face 1311 and the fourth end face 1312 are spaced apart along the splicing direction of the multiple wire clip assemblies 1. The connecting post 132 is disposed on the third end face 1311, and the axial direction of the connecting post 132 is consistent with the axial direction of the first connecting hole 1213. In adjacent first wire clip assemblies 1A and second wire clip assemblies 1B, the connecting post 132 of the second wire clip assembly 1B extends into any of the first connecting holes 1213 of the first wire clip assembly 1A, and is connected to the first connecting hole 1213. The connecting post 132 is rotatable relative to the first connecting hole 1213.

[0063] When the connecting post 132 of the second line clip assembly 1B is inserted into the first connecting hole 1213 of the first line clip assembly 1A, the mechanical transmission path of the splicing direction is maintained through the axial consistency design (the connecting post 132 and the first connecting hole 1213 are axially aligned). The characteristic that the connecting post 132 can rotate relative to the first connecting hole 1213 allows the adjacent first line clip assembly 1A and second line clip assembly 1B to rotate independently around the splicing axis, thereby flexibly adjusting the orientation of their respective wire holes 11.

[0064] In order to achieve a rotatable connection between the two second line clip assemblies 1B, in some optional embodiments, a second connecting hole 1313 is provided on the fourth end face 1312, and the axial direction of the second connecting hole 1313 is consistent with the axial direction of the connecting post 132; in two adjacent second line clip assemblies 1B, the connecting post 132 of one second line clip assembly 1B extends into the second connecting hole 1313 of the other second line clip assembly 1B and is connected with the second connecting hole 1313; wherein, the connecting post 132 is rotatable relative to the second connecting hole 1313.

[0065] Thus, when two adjacent second line clamp assemblies 1B are connected by inserting the connecting post 132 into the second connecting hole 1313, their axial consistency ensures the continuity of load transmission in the splicing direction. The characteristic that the connecting post 132 can rotate relative to the second connecting hole 1313 allows multiple second line clamp assemblies 1B to adjust the orientation of the wire hole 11 step by step along the splicing chain.

[0066] In some specific embodiments, the connecting post 132 is a stud, and the first connecting hole 1213 and the second connecting hole 1313 are both threaded holes.

[0067] When the connecting post 132 is screwed into the threaded hole of the first connecting hole 1213 or the second connecting hole 1313, the axial preload generated by the thread engagement can effectively suppress the unexpected rotation of the first wire clamp assembly 1A and the second wire clamp assembly 1B under vibration, ensuring the reliability of the angle locking of the wire passage hole 11 after adjustment. At the same time, the progressive engagement characteristic of the threaded pair allows the operator to fine-tune the rotational damping between adjacent first wire clamp assemblies 1A and second wire clamp assemblies 1B, or between two adjacent second wire clamp assemblies 1B, by controlling the screw-in depth. For example, in areas where the wiring direction needs to be frequently adjusted (such as at door hinges), the thread engagement can be appropriately loosened to retain flexible steering capability, while in fixed path sections it can be fully tightened to achieve rigid fixation.

[0068] In this way, the free rotation function of the connecting post 132 relative to the first connecting hole 1213 or the second connecting hole 1313 is retained, and the tensile strength of the splicing node is improved by the shear resistance of the thread, so that the fixed angle of multiple wire harnesses 20 can be maintained for a long time under multi-directional vibration conditions.

[0069] Since the first wire clip assembly 1A is formed by two first wire clip pieces 12 fastening together, and the second wire clip assembly 1B is formed by two first wire clip assemblies 1A fastening together, the formation of the wire passage hole 11 can be as follows: the first wire clip body 121 forms a first wire passage groove 1214, and the second wire clip body 131 forms a second wire passage groove 1314; in the first wire clip assembly 1A, the two first wire passage grooves 1214 fasten together to form the wire passage hole 11, and the two first wire passage grooves 1214 have the same shape and equal size; in the second wire clip assembly 1B, the first wire passage groove 1214 and the second wire passage groove 1314 fasten together to form the wire passage hole 11, and the first wire passage groove 1214 and the second wire passage groove 1314 have the same shape and equal size.

[0070] The equal shape and size of the two first wire passage grooves 1214 in the first wire clip assembly 1A, and the symmetrical matching of the first wire passage groove 1214 and the second wire passage groove 1314 in the second wire clip assembly 1B, ensure that the inner wall contour of each wire passage hole 11 remains uniformly closed, thus avoiding uneven local pressure on the wire harness 20 due to misalignment of the grooves to a certain extent.

[0071] To achieve the connection between the two first wire-clamping components 12, or the connection between the first wire-clamping component 12 and the second wire-clamping component 13, in some embodiments, the first wire-clamping body 121 has a first fastening hole 1215, which penetrates the first wire-clamping body 121 and is located to the side of the first wire-passing groove 1214; the second wire-clamping body 131 has a second fastening hole 1315, which penetrates the second wire-clamping body 131 and is located in the second wire-passing groove. 1314 on the side; in each first wire clip assembly 1A, two first fastening holes 1215 are arranged opposite to each other, and two first wire clip members 12 are connected together by first fasteners (not shown in the figure) passing through the two first fastening holes 1215; in each second wire clip assembly 1B, the first fastening hole 1215 and the second fastening hole 1315 are arranged opposite to each other, and the first wire clip member 12 and the second wire clip member 13 are connected together by second fasteners (not shown in the figure) passing through the first fastening hole 1215 and the second fastening hole 1315.

[0072] In this way, when the two first wire-clamping parts 12 are fastened together, the first fastener passes through the side of the first wire-passing groove 1214. When the first wire-clamping part 12 and the second wire-clamping part 13 are fastened together, the second fastener can pass through the side of the second wire-passing groove 1314. This can avoid interfering with the path of the wire harness 20 in the wire-passing hole 11 to a certain extent, and apply balanced closing pressure through symmetrically distributed fastening points to ensure the tightness of the inner wall of the wire-passing hole 11 in wrapping the wire harness 20.

[0073] Furthermore, in some alternative embodiments, both the first fastening hole 1215 and the second fastening hole 1315 are threaded holes.

[0074] In this way, when the first or second fastener is screwed in, the progressive engagement of the threaded pair can generate an axial preload, forcing the two first wire clamping parts 12 or the first wire clamping part 12 and the second wire clamping part 13 to fit tightly together. This can eliminate the assembly gap of the closed surface of the wire hole 11 to a certain extent and enhance the radial clamping stability of the wire harness 20 by the first wire clamping assembly 1A or the second wire clamping assembly 1B.

[0075] To further improve the connection reliability of the two first card wire pieces 12 in the first card assembly 1A, and the connection reliability of the first card wire piece 12 and the second card wire piece 13 in the second card assembly 1B, in some optional embodiments, the axial direction of the first fastening hole 1215 is perpendicular to the axial direction of the wire passage hole 11, and the axial direction of the second fastening hole 1315 is perpendicular to the axial direction of the wire passage hole 11.

[0076] In this way, when the first and second fasteners are screwed in, a locking force is applied along the direction perpendicular to the extension of the wire harness 20. This not only avoids axial compression deformation of the wire harness 20 during the fastening operation to a certain extent, but also enhances the shear strength of the mating surfaces of the two first wire clamping parts 12 and the shear strength of the mating surfaces of the first wire clamping part 12 and the second wire clamping part 13 through lateral constraint.

[0077] It should be noted that since the surfaces of many wire harnesses 20 are circumferential, the longitudinal cross-sectional shape of the wire hole is circular in the specific implementation of this embodiment.

[0078] This embodiment also provides a vehicle, including a frame, three-phase wires, and the wiring harness fixing structure 10 in the above embodiments; wherein, each wire clamp assembly 1 is connected to the frame, and each wire harness 20 in the three-phase wires is correspondingly inserted through the wire hole 11 of the wiring harness fixing structure 10.

[0079] Specifically, the first line clamp assembly 1A is connected to the vehicle frame via a first fastener, and the second line clamp assembly 1B is connected to the vehicle frame via a second fastener. Both the first and second fasteners can be threaded fasteners, such as screws. No specific restrictions are placed on the type of the first and second fasteners.

[0080] It should be noted that the wire harness fixing structure 10 has been described in detail in the above embodiments, and will not be repeated here.
