Wire harness fixing member and vehicle

Abstract

The embodiment of the application provides a wire harness fixing part for fixing connection between a component and a wire harness. The wire harness fixing part comprises a clamping part and a fixing part. The clamping part is used for being inserted into a mounting hole along a first direction. At least one side of the clamping part extends a protrusion along a second direction. The protrusion is used for being clamped at a mouth along part of the mounting hole which is away from the fixing part. The first direction intersects with the second direction. The fixing part is used for fixing the wire harness. The clamping part is fixedly arranged on the fixing part. A clamping gap is arranged between the fixing part and the protrusion along the first direction. In this way, the part of the clamping part corresponding to the clamping gap is as close as possible to the mounting hole in size and shape, so as to further reduce the gap between the clamping part and the mounting hole, and then reduce the shaking. During installation, only the protrusion needs to be clamped in place. Whether the wire harness fixing part is installed in place can be judged by observing whether the protrusion is clamped in place.

Description

Technical Field

[0001] This application belongs to the field of vehicle technology, specifically relating to a wiring harness fastener and a vehicle. Background Technology

[0002] Existing vehicles typically use cables to connect electronic devices. With vehicle movement, these cables can easily sway within the wiring harness. This can cause rattling noises inside the vehicle and compromises the reliability of the connection between the cables and the electronic equipment. Therefore, technicians usually use fasteners to bundle and secure the cables to the vehicle's sheet metal. One existing fastener includes a cable tie and a cable management plate. After the cable harness is secured to the cable management plate, the cable tie is inserted into a mounting hole on the vehicle's sheet metal.

[0003] The cedar head is a flat block structure with multiple stepped retaining teeth on opposite sides in the thickness direction, arranged side-by-side along the height direction. During use, the cedar head does not need to be fully inserted into the mounting hole; it is sufficient to ensure the sheet metal part is engaged between two adjacent stepped retaining teeth. However, the cedar head has poor retention; after insertion into the mounting hole, the fastener is prone to wobbling relative to the sheet metal part under external force, making it difficult to guarantee the wiring harness's fixation. Furthermore, due to the multiple stepped retaining teeth on the cedar head, during vehicle assembly, technicians find it difficult to visually determine whether the cedar head on the fastener is properly inserted. Summary of the Invention

[0004] In view of the above problems, the present invention is proposed to provide a wiring harness fastener and vehicle that overcomes or at least partially solves the above problems.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a wire harness fastener for fixing a component and a wire harness, the wire harness fastener including a snap-fit ​​part and a fixing part;

[0007] The snap-fit ​​portion is used to be inserted into the mounting hole along the first direction, and at least one side of the snap-fit ​​portion has a protrusion extending along the second direction. The protrusion is used to snap into the edge of the mounting hole facing away from the fixing portion. The first direction intersects the second direction.

[0008] The fixing part is used to fix the wire harness, the snap-fit ​​part is fixedly disposed on the fixing part, and a snap-fit ​​gap is provided between the fixing part and the protrusion in the first direction.

[0009] Optionally, the fixing part includes a first fixing plate and a second fixing plate;

[0010] The snap-fit ​​portion is fixed to the first fixing plate, and the second fixing plate is disposed on the side of the first fixing plate along a third direction and extends to the side opposite to the snap-fit ​​portion; the third direction intersects with the first direction.

[0011] Optionally, a third fixing plate extends from the side of the first fixing plate along the second direction; the dimension of the third fixing plate along the third direction is smaller than that of the first fixing plate.

[0012] Optionally, the fixing part includes a first straight segment, a second straight segment, and a curved segment, wherein the first straight segment and the second straight segment are arranged at an angle, and the curved segment is connected between the first straight segment and the second straight segment.

[0013] Optionally, the end of the first fixing plate is provided with a first raised edge, which extends along the thickness direction of the first fixing plate.

[0014] Optionally, the end of the second fixing plate is provided with a second raised edge, the second raised edge extends along the thickness direction of the second fixing plate, and the first raised edge and the second raised edge are integrally formed.

[0015] Optionally, the end of the third fixing plate is provided with a third raised edge, which extends along the thickness direction of the third fixing plate.

[0016] Optionally, the wire harness fastener includes a skirt structure;

[0017] The skirt structure is arranged around the snap-fit ​​portion. The skirt structure includes a large end and a small end. The small end is fixedly connected to the fixing portion, and the large end is arranged facing the first direction.

[0018] Optionally, the bump has a solid structure, and the side of the bump facing the first direction is an inclined surface relative to the first direction.

[0019] Optionally, the snap-fit ​​portion is provided with a cavity.

[0020] Optionally, at least two cavities are provided and arranged at intervals along the second direction, with a solid partition between adjacent cavities.

[0021] Secondly, embodiments of this application provide a vehicle that includes a wiring harness fastener as described above.

[0022] In this embodiment, compared to existing fasteners using cedar tree branches, the wire harness fastener described in this embodiment has its mounting hole wall and edge engaged within the engagement gap between the protrusion of the engagement part and the fixing part during use. This allows the portion of the engagement part corresponding to the engagement gap to be as close as possible in size and shape to the mounting hole, further reducing the gap between the engagement part and the mounting hole. After the engagement part is installed in place, it is less likely to wobble within the mounting hole. This helps ensure the stability of the wire harness when fixed to external parts and minimizes cable movement.

[0023] The wiring harness fastener described in this embodiment only requires the protrusion to be snapped into place during installation. Technicians only need to observe whether the protrusion is properly snapped in place to determine if the wiring harness fastener is installed correctly. This simplifies the production process and improves vehicle production efficiency.

[0039] Reference Figure 1 and Figure 4 This diagram illustrates the structure of a wire harness fastener according to an embodiment of this application, specifically including a snap-fit ​​part 1 and a fixing part 2. The snap-fit ​​part 1 is the portion of the wire harness fastener used to snap into a mounting hole on an external component. In use, the snap-fit ​​part 1 can be inserted into the mounting hole on the external component along a first direction, which is... Figure 1 The Z direction is shown. Along the second direction, protrusions 11 extending in the second direction are provided on one or both sides of the engaging portion 1. The second direction is... Figure 1 The X direction is shown. When fixing the wire harness, the protrusion 11 of the snap-fit ​​part 1 is inserted into the mounting hole with an interference fit. After the snap-fit ​​part 1 is inserted into place, the protrusion 11 can snap onto the edge of the mounting hole facing the first direction to prevent the snap-fit ​​part 1 from exiting the mounting hole facing away from the first direction. It should be noted that the first direction and the second direction are intersecting. In the embodiments of this application, the first direction and the second direction are preferably arranged orthogonally, that is, the angle between the first direction and the second direction is 90 degrees. In some embodiments of this application, the first direction and the second direction may also be in a normal intersecting relationship, that is, the angle between the first direction and the second direction is an acute angle or an obtuse angle.

[0040] Reference Figure 1 and Figure 3 The fixing part 2 is the portion on the wire harness fixing component used for fixing and connecting the wire harness. The wire harness can be a structure formed by bundling several cables connecting electronic devices together using cable ties, tape, etc. The fixing part 2 is fixedly connected to the snap-fit ​​part 1, and based on this fixed connection, the wire harness is fixed to the external part. The fixed connection between the fixing part 2 and the snap-fit ​​part 1 can be achieved in various ways, such as bonding, welding, riveting, screwing, interference fit, etc. In this application, the fixing part 2 and the snap-fit ​​part 1 are preferably fixed by integral molding. This can give the fixing part 2 and the snap-fit ​​part 1 better connection strength, and at the same time simplify the assembly process.

[0041] Reference Figure 4 and Figure 6 In some embodiments of this application, the end of the snap-fit ​​portion 1 facing away from the first direction may be fixedly connected to the fixing portion 2. The protrusion 11 on the snap-fit ​​portion 1 and the fixing portion 2 are arranged at intervals in the first direction, so that there is a snap-fit ​​gap 4 between the end of the protrusion 11 facing away from the first direction and the end of the fixing portion 2 facing the first direction. After the snap-fit ​​portion 1 is inserted into the mounting hole of the external part, the part part where the mounting hole is located can be snapped into the snap-fit ​​gap 4.

[0042] In existing fasteners, external parts are typically snapped between two adjacent stepped teeth of the fastener's "tree head." To prevent excessive insertion force of the tree head, the portion between the two adjacent stepped teeth needs to be designed to be smaller, resulting in a larger gap between the tree head and the mounting hole after installation. This causes the tree head to wobble easily within the mounting hole, with a significant amount of wobble. This is detrimental to the stable fixation of the wire harness. Compared to existing fasteners using tree heads, the wire harness fastener described in this embodiment has the mounting hole wall and edge snapped into the snap-fit ​​gap 4 between the protrusion 11 of the snap-fit ​​part 1 and the fixing part 2 during use. This allows the portion of the snap-fit ​​part 1 corresponding to the snap-fit ​​gap 4 to be as close as possible to the mounting hole in size and shape, further reducing the gap between the snap-fit ​​part 1 and the mounting hole. After the snap-fit ​​part 1 is installed, it is less likely to wobble within the mounting hole. This helps ensure the stability of the wire harness when fixed to external parts and minimizes cable wobble.

[0043] In existing fasteners, multiple stepped teeth are arranged on the top of the fastener. During use, not all stepped teeth engage with the mounting holes. This means that after the fastener is installed in the mounting holes, some stepped teeth remain unengaged. During final assembly, technicians cannot visually determine whether the fastener is properly installed and need to further inspect the connection between the fastener and external parts. This increases the workload and reduces production efficiency. The wiring harness fastener described in this embodiment only requires the protrusion 11 to be engaged. Technicians only need to observe whether the protrusion 11 is engaged to determine if the wiring harness fastener is properly installed. This simplifies the production process and improves vehicle production efficiency.

[0044] In some embodiments of this application, the wire harness fastener can be specifically applied to automobiles to fix the wire harness inside the automobile to the sheet metal parts of the automobile. The sheet metal parts of the automobile are structures formed by sheet metal processing, and have mounting holes adapted to the wire harness fastener. When fixing the wire harness, the wire harness can be fixed to the fixing part 2 by means of cable ties, tape, adhesive, etc. The snap-fit ​​part 1 of the wire harness fastener is first inserted into the mounting hole with an interference fit. After the snap-fit ​​part 1 is inserted into place, the sheet metal part where the mounting hole is located is exactly locked in the snap-fit ​​gap 4 between the protrusion 11 of the snap-fit ​​part 1 and the fixing part 2. The protrusion 11 is engaged with the edge of the mounting hole facing away from the fixing part 2 to prevent the snap-fit ​​part 1 from coming out of the fixing hole facing away from the first direction. When the snap-fit ​​part 1 continues to go deeper in the first direction, the fixing part 2 will interfere with the edge of the mounting hole to prevent the snap-fit ​​part 1 from going deeper. Of course, the wire harness fastener described in this application embodiment can also be used for the fixed connection of wire harnesses with other structures, such as the fixed connection of wire harnesses with equipment.

[0045] In some embodiments of this application, the fixing part 2 includes a first fixing plate 21 and a second fixing plate 22, that is, the fixing part 2 is specifically a plate structure including the first fixing plate 21 and the second fixing plate 22. The snap-fit ​​part 1 is fixed to the first fixing plate 21, and the second fixing plate 22 is disposed on the side of the first fixing plate 21 along a third direction and extends towards the side opposite to the snap-fit ​​part 1. The third direction intersects with the first direction. The third direction is... Figure 2 The Y direction is shown. In other words, the first direction and the third direction can be orthogonal, meaning the angle between them is 90 degrees; or they can be intersecting, meaning the angle is acute or obtuse. Based on this arrangement, when the wire harness is fixed to the fixing part 2, its two ends along different radial directions can be connected to the first fixing plate 21 and the second fixing plate 22 respectively. That is, the first fixing plate 21 and the second fixing plate 22 provide fixed support for the wire harness from two different directions. This improves the fixing effect of the fixing part 2 on the wire harness, making the connection between the wire harness and the fixing part 2 more stable and reliable. Simultaneously, the second fixing plate 22 strengthens the first fixing plate 21, thereby increasing the structural strength of the fixing part 2 and reducing the possibility of deformation. The first fixing plate 21 and the second fixing plate 22 also protect the wire harness, preventing it from being cut or scratched by protrusions, edges, or other structures on the surface of external parts under vibration.

[0046] In some embodiments of this application, the second direction and the third direction may be the same direction, or the second direction and the third direction may be orthogonal, that is, the angle between the second direction and the third direction is 90 degrees; the second direction and the third direction may also be in a general intersecting relationship, that is, the angle between the first direction and the third direction is greater than or less than 90 degrees.

[0047] In some embodiments of this application, the first direction, the second direction, and the third direction intersect but are not coplanar. In other words, there exists a base point in space, and the first direction, the second direction, and the third direction all intersect at the base point. The first direction is not located in the plane defined by the second direction and the third direction, or in other words, the first direction intersects in the plane defined by the second direction and the third direction; the second direction is not located in the plane defined by the first direction and the third direction, or in other words, the second direction intersects in the plane defined by the first direction and the third direction; the third direction is not located in the plane defined by the first direction and the second direction, or in other words, the third direction intersects in the plane defined by the first direction and the second direction.

[0048] Reference Figure 3 and Figure 5In some embodiments of this application, a third fixing plate 23 extends from the side of the first fixing plate 21 along the second direction. The third fixing plate 23 can increase the connection points between the wire harness and the fixing component. Since the first fixing plate 21 has a larger dimension in the third direction, the strength of the fixing part 2 can be effectively guaranteed. Based on this, the dimension of the third fixing plate 23 in the third direction can be smaller than that of the first fixing plate 21. This allows the third fixing plate 23 to match the size of the wire harness as closely as possible in the third direction, i.e., the radial direction of the wire harness, thereby facilitating the fixing of the wire harness to the third fixing plate 23 using fixing tools such as tape and cable ties. At the same time, this can also reduce the material cost of the fixing part 2, thereby reducing the overall production and processing cost of the wire harness fixing component.

[0049] In some embodiments of this application, the fixing part 2 includes a first straight segment 24, a second straight segment 25, and a bent segment 26. The first segment and the second segment are arranged at an angle, and the bent segment 26 connects the first straight segment 24 and the second straight segment 25. In other words, the first straight segment 24 and the second straight segment 25 have different extension directions; the first straight segment 24 and the second straight segment 25 are connected by the bent segment 26, so that the fixing part 2 presents a bent shape. This allows the wire harness fixing member to be applied in wiring scenarios where the wire harness has bends, so that the wire harness fixing member has a good fixing effect even for wire harnesses with bends. Specifically, when the axial direction of the wire harness changes, the fixing part 2 also has a bend adapted to the wire harness. After the wire harness is bent, the two straight-lined portions of the wire harness arranged at an angle are respectively fixed to the first straight segment 24 and the second straight segment 25 of the fixing part 2, and the bent portion of the wire harness is fixed to the bent segment 26 of the fixing part 2. The bending direction of the fixing part 2 can be determined according to the actual direction of the wire harness. For example, the bending direction of the first bending plate can be set towards the first direction. Specifically, the extension direction of the first straight segment 24 is set along the second direction, and the extension direction of the second straight segment 25 is set along the first direction. Alternatively, the bending direction of the first bending plate can be set away from the first direction. Specifically, the extension direction of the first straight segment 24 is set along any direction relative to the first direction, and the extension direction of the second straight segment 25 is set away from the first direction.

[0050] In some embodiments of this application, reference may be made to Figure 1 , Figure 2 and Figure 3As shown, the first direction is preferably orthogonal to the second direction, that is, the first direction and the second direction are arranged at a 90-degree angle. The third direction is orthogonal to both the first and second directions and is not coplanar; that is, the first direction is arranged at a 90-degree angle to the second and third directions respectively. In other words, there is a base point in space, and the first direction, the second direction, and the third direction form a spatial rectangular coordinate system based on this base point. Based on this coordinate system, the latching part 1 can be a flat block structure. The length direction of the latching part 1 is arranged along the first direction, the width direction is arranged along the second direction, and the thickness direction is arranged along the third direction. The protrusions 11 are provided on both sides of the latching part 1 in the width direction, with the end facing the first direction forming an inclined surface 111, and the end facing away from the first direction being spaced apart from the fixing part 2.

[0051] The fixing part 2 includes a first fixing plate 21, a second fixing plate 22, and a third fixing plate 23. In the first fixing plate 21, the thickness direction of a first straight segment 24 is set along a first direction, the length direction along a second direction, and the width direction along a third direction. The length direction of a second straight segment 25 is set along the first direction, the thickness direction along the second direction, and the width direction along a third direction. A bent end connects the ends of the first straight segment 24 and the second straight segment 25 that are close to each other. The second fixing plate 22 is located on the side of the first fixing plate 21 along the third direction and extends away from the snap-fit ​​part 1. The third fixing plate 23 is located on one side edge of the first fixing plate 21 in the second direction. Specifically, the thickness direction of the third fixing plate 23 is arranged along the first direction, the length direction along the second direction, and the width direction along a third direction. One end of the third fixing plate 23 in the length direction is connected to one end of the first straight segment 24 in the length direction. During installation, the first fixing plate 21 and the third fixing plate 23 contact the wire harness from the same radial direction, and the second fixing plate 22 contacts the wire harness from another radial direction. The fixing plate is then fixed to the wire harness using tools such as tape or cable ties.

[0052] In some embodiments of this application, the end of the first fixing plate 21 is provided with a first raised edge 211, which extends along the thickness direction of the first fixing plate 21. The first raised edge 211 is a plate-like structure that protrudes from the end of the first fixing plate 21 along the thickness direction of the first fixing plate 21. After the wire harness is fixed to the first fixing plate 21 by fixing tools such as tape or cable ties, the first raised edge 211 can prevent the tape or cable ties from detaching from the first fixing plate 21. At the same time, the first raised edge 211 can also serve as a reinforcing structure to improve the structural strength of the first fixing plate 21, thereby ensuring the fixing effect of the wire harness fixing component on the wire harness.

[0053] In some embodiments of this application, the end of the second fixing plate 22 is provided with a second raised edge 221, which extends along the thickness direction of the second fixing plate 22. The second raised edge 221 is a plate-like structure that protrudes from the end of the second fixing plate 22 along the thickness direction of the second fixing plate 22. After the wire harness is fixed to the first fixing plate 21 and the second fixing plate 22 by fixing tools such as tape or cable ties, the second raised edge 221, together with the first raised edge 211, can prevent the tape or cable ties from detaching from the first fixing plate 21 and the second fixing plate 22. At the same time, the setting of the second raised edge 221 can serve as a reinforcing structure to improve the structural strength of the second fixing plate 22, thereby ensuring the fixing effect of the wire harness fixing component on the wire harness. The first raised edge 211 and the second raised edge 221 are preferably integrally molded. This can reduce the processing difficulty and save processing costs on the one hand, and further improve the strengthening effect of the first raised edge 211 and the second raised edge 221 on the strength of the wire harness fixing component on the other hand.

[0054] In some embodiments of this application, the end of the third fixing plate 23 is provided with a third raised edge 231, which extends along the thickness direction of the third fixing plate 23. The third raised edge 231 is a plate-like structure that protrudes from the end of the third fixing plate 23 along the thickness direction of the third fixing plate 23. After the wire harness is fixed to the third fixing plate 23 by fixing tools such as tape or cable ties, the third raised edge 231 can prevent the tape or cable ties from detaching from the third fixing plate 23. At the same time, the setting of the third raised edge 231 can serve as a reinforcing structure to improve the structural strength of the third fixing plate 23, thereby ensuring the fixing effect of the wire harness fixing component on the wire harness.

[0055] In some embodiments of this application, the wire harness fixing component further includes a skirt structure 3. The skirt structure 3 is a trumpet-shaped structure with a sidewall surrounding the snap-fit ​​portion 1. The skirt structure 3 has an opening at one end facing away from the first direction and an opening at the other end facing the first direction. The opening at the end of the skirt structure 3 facing away from the first direction is smaller, designated as a small opening 32; the opening at the end of the skirt structure 3 facing the first direction is larger, designated as a large opening 31. The small opening 32 is fixedly connected to the fixing portion 2, and the portion of the snap-fit ​​portion 1 fixedly connected to the fixing portion 2 is enclosed in the small opening 32. The snap-fit ​​portion 1 extends out of the skirt structure 3 along the first direction, or in other words, the dimension of the snap-fit ​​portion 1 in the first direction is larger than the dimension of the skirt structure 3 in the first direction. When the snap-fit ​​portion 1 is snapped into the mounting hole of the external component, the skirt structure 3 can adapt to the gap between the fixing portion 2 and the external component and elastically support itself between the fixing portion 2 and the external component. When the wire harness fastener wobbles relative to external parts, the skirt structure 3 can provide a certain resistance to reduce the wobbling of the wire harness fastener, thereby improving the fixing effect of the wire harness fastener on the wire harness.

[0056] In some embodiments of this application, the protrusion 11 is a solid structure. This ensures that the protrusion 11 itself has good structural strength, thereby ensuring the fixed connection effect between the wire harness fastener and the external parts. The side of the protrusion 11 facing the first direction is an inclined surface 111 relative to the first direction, that is, along the first direction, the size of the protrusion 11 gradually decreases in the second direction. This can reduce the insertion force when the snap-fit ​​part 1 is inserted into the mounting hole while ensuring the fixing effect, thereby facilitating the installation and use of the wire harness fastener.

[0057] In some embodiments of this application, a cavity 12 is provided inside the snap-fit ​​portion 1. This saves material and also facilitates a certain degree of elastic deformation of the snap-fit ​​portion 1 during interference fitting, thereby reducing the insertion force of the snap-fit ​​portion 1 when it is interference-fitted into the mounting hole to a certain extent. (See reference...) Figure 7 , Figure 8 The cavity 12 can extend and penetrate the first fixing plate 21.

[0058] refer to Figure 3 In some embodiments of this application, at least two cavities 12 are provided and arranged at intervals along a second direction, with a solid partition 13 between adjacent cavities 12. Specifically, in this application, the snap-fit ​​portion 1 may have two cavities 12. The two cavities 12 extend along a first direction and are arranged at intervals along a second direction, with a wall-like structure between them, which is the solid partition 13. The protrusion 11 may also have three cavities 12. The three cavities 12 extend along a first direction and are arranged at intervals along a second direction, with a wall-like structure between each pair of adjacent cavities 12, which is the solid partition 13. The number of cavities 12 may also be three, four, or even more, depending on the actual needs. With the support of the solid partition 13, the snap-fit ​​portion 1 can ensure a certain structural strength, preventing insufficient strength of the snap-fit ​​portion 1 due to the opening of the cavities 12. The cross-sectional projection of the cavity 12 in the first direction may be set according to actual needs. For example, the cross-sectional projection of cavity 12 in the first direction can be rectangular, triangular, circular, etc.

[0059] In summary, the wire harness fixing component described in the embodiments of this application may include at least the following advantages:

[0060] Compared to existing fasteners using cedar tree stumps, the wire harness fastener described in this embodiment has its mounting hole wall and edge engaged within the engagement gap 4 between the protrusion 11 of the engagement part 1 and the fixing part 2 during use. This allows the portion of the engagement part 1 corresponding to the engagement gap 4 to be as close as possible to the mounting hole in size and shape, further reducing the gap between the engagement part 1 and the mounting hole. After the engagement part 1 is installed in place, it is less likely to wobble within the mounting hole. This helps ensure the stability of the wire harness when fixed to external parts and minimizes cable movement.

[0061] The wiring harness fastener described in this embodiment only requires the protrusion 11 to be snapped into place during installation. Technicians only need to observe whether the protrusion 11 is properly snapped in to determine if the wiring harness fastener is installed correctly. This simplifies the vehicle manufacturing process and improves its efficiency.

[0062] This application also provides a vehicle that includes a wiring harness fastener as described above.

[0063] For example, in the embodiments of this application, the vehicle may include small cars, medium-sized cars, sedans, trucks, trailers, CDVs (Car Derived Vans), MPVs (multi-Purpose Vehicles), SUVs (Sport Utility Vehicles), etc. The specific type of vehicle is not limited in the embodiments of this application.

[0064] The wiring harness fastener can mate with sheet metal parts on the vehicle. Specifically, the sheet metal part has mounting holes that match the snap-fit ​​portion 1 on the wiring harness fastener. During installation, the wiring harness on the vehicle is secured to the fixing portion 2 of the wiring harness fastener using cable ties or tape. The snap-fit ​​portion 1 and the protrusion 11 on the snap-fit ​​portion 1 are interference-fitted into the mounting holes. After insertion, the sheet metal part is precisely engaged in the gap between the protrusion 11 and the fixing portion 2. The protrusion 11 stops at the edge of the mounting hole facing away from the fixing portion 2 to prevent the wiring harness fastener from dislodging from the mounting hole.

[0065] The vehicle described in this application embodiment may include at least the following advantages:

[0066] The vehicle described in this application uses the wiring harness fastener described above. Compared to existing fasteners using cedar tree studs, the wiring harness fastener described in this application, during use, has the wall and edge of the mounting hole engaged within the engagement gap 4 between the protrusion 11 of the engagement part 1 and the fixing part 2. This allows the portion of the engagement part 1 corresponding to the engagement gap 4 to be as close as possible to the mounting hole in size and shape, further reducing the gap between the engagement part 1 and the mounting hole. After the engagement part 1 is installed in place, it is less likely to wobble within the mounting hole. This helps ensure the stability of the wiring harness when fixed to external parts and minimizes cable movement. In summary, using the wiring harness fastener described above in this application can ensure the wiring harness is securely fixed to the vehicle, thereby reducing abnormal noise caused by wiring harness movement during vehicle operation. Simultaneously, this also ensures the reliability of the connection between the wiring harness and the equipment on the vehicle.

[0067] The wiring harness fastener described in this embodiment only requires the protrusion 11 to be snapped into place during installation. Technicians only need to observe whether the protrusion 11 is properly snapped in to determine if the wiring harness fastener is installed correctly. This simplifies the vehicle manufacturing process and improves manufacturing efficiency.
