Alternatively, bolts or welding can be used to fix the wiring harness to the vehicle body. However, during installation, gaps may appear at the bolt or weld connection points, causing problems such as water leakage in the vehicle body. Moreover, the bolt and welding methods require a large amount of operating space, which is not conducive to the installation of wiring harness clips. Utility Model Content

[0026] 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.

[0027] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. 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.

[0028] 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.

[0029] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. 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.

[0030] 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.

[0031] 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.

[0032] This application provides a vehicle. 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 a vehicle, there are various electrical devices, including but not limited to: electric motors, air conditioning systems, lighting systems, and infotainment systems. These various electrical devices are connected by wiring harnesses. The wiring harnesses ensure effective electrical connections between these electronic devices. The arrangement and routing of the wiring harnesses need to be reasonably arranged within the vehicle to adapt to the interior space without affecting the installation and operation of other components.

[0033] To ensure stability when the wiring harness is connected, drilling holes in the vehicle body is used to clip the harness to the vehicle body. However, due to limitations in waterproofing, space, and the strength of the vehicle body sheet metal, this clipping method cannot be used. Alternatively, bolts or welding can be used to fix the wiring harness to the vehicle body, but during installation, gaps may appear at the bolt or weld joints, causing problems such as water leakage. Moreover, bolts and welding require a large amount of operating space. Installing the fixing clips for securing the wiring harness after installing other vehicle components is also difficult because these other components occupy space.

[0034] Based on this, refer to Figures 1-3This application provides a fixing component 20 for use in a vehicle. The fixing component 20 includes a first fixing member 2 and a fixing bracket 3. The first fixing member 2 is fixed to the vehicle body 10. The fixing bracket 3 has a second fixing member 31, which is snapped into the first fixing member 2. The fixing bracket 3 is detachably connected to the wiring harness 4.

[0035] The first fastener 2 can be pre-embedded in the body 10. During the processing of the body 10, the first fastener 2 can be pre-installed on the body 10 according to the arrangement and routing of the wiring harness 4, providing sufficient installation space for the first fastener 2 and ensuring the reliability and tightness of the installation between the first fastener 2 and the body 10. Moreover, the pre-installation of the first fastener 2 on the body 10 before leaving the factory can improve the sealing during installation and enhance waterproof performance. For example, the first fastener 2 can be welded to the body 10.

[0036] When it is necessary to install the wiring harness 4, the second fixing member 31 of the fixing bracket 3 can be connected to the first fixing member 2 first, and then the wiring harness 4 can be snapped onto the fixing bracket 3. Alternatively, the wiring harness 4 can be snapped onto the fixing bracket 3 first, and then the second fixing member 31 of the fixing bracket 3 can be connected to the first fixing member 2. The wiring harness 4 can be securely installed on the vehicle body 10 through the fixing component 20, thereby providing a reliable fixing point for the wiring harness 4.

[0037] The first fixing member 2 is directly fixed to the vehicle body 10, providing a stable mounting point for the mounting bracket 3. This ensures that the fixing component 20 is securely installed on the vehicle body 10 and provides reliable support for the wiring harness 4. The position of the first fixing member 2 is rationally arranged according to the routing of the wiring harness 4, so that the first fixing member 2 fixes the mounting bracket 3 to the vehicle body 10, and the mounting bracket 3 fixes the wiring harness 4 to the vehicle body 10, thus fixing the routing and position of the wiring harness 4.

[0038] The second fixing member 31 snaps into the first fixing member 2, which simplifies the connection between the fixing bracket 3 and the first fixing member 2. The fixing bracket 3 is detachably connected to the wire harness 4, allowing the wire harness 4 to be removed from the fixing bracket 3 for repair or replacement.

[0039] The end of the wiring harness 4 may also be provided with a wiring harness terminal 41, which can be plugged into an electronic device. The wiring harness terminal 41 or the wiring harness 4 is fixed to the vehicle body 10 by the fixing component 20 to prevent the wiring harness terminal 41 from falling off the electronic device due to vehicle vibration when the vehicle is in motion. The wiring harness terminal 41 can also be plugged into another wiring harness terminal 41. The fixing component 20 provides position support for the wiring harness terminal 41 to prevent the wiring harness terminal 41 from falling off the other wiring harness terminal 41 due to vehicle vibration when the vehicle is in motion.

[0040] The wire harness 4 can be formed by wrapping multiple wire harness strips. The outer side of the wire harness 4 is provided with a snap-fit ​​protrusion that snaps into the fixing bracket 3. The outer side of the wire harness terminal 41 is also provided with a snap-fit ​​protrusion that snaps into the fixing bracket 3.

[0041] For example, the first fixing member 2 can be a fixing post, and the second fixing member 31 can be a fixing hole 311. The fixing post can be snapped into the fixing hole 311 for fixation.

[0042] The fixing component 20 provided in this application embodiment includes a first fixing member 2 and a fixing bracket 3. The first fixing member 2 is pre-installed on the vehicle body 10, and the wire harness 4 is then installed on the first fixing member 2 through the fixing bracket 3. This can ensure the reliability and tightness of the installation between the first fixing member 2 and the vehicle body 10, and can also improve the waterproof performance. The fixing component 20 is firmly installed on the vehicle body 10, which can provide a reliable fixing point for the wire harness 4.

[0043] Reference Figures 2-3 In one possible implementation of this application, the first fixing member 2 includes a stud 21, and the second fixing member 31 includes a fixing hole 311. The inner wall of the fixing hole 311 is provided with a plurality of elastic protrusions 312. One end of the elastic protrusion 312 is connected to the inner wall of the fixing hole 311, and the other end is inclined toward the center of the fixing hole 311. The other end of the elastic protrusion 312 cooperates with the stud 21 to limit the position of the fixing bracket 3, thereby fixing the fixing bracket 3 on the first fixing member 2.

[0044] When installing the fixing bracket 3, the end of the elastic protrusion 312 connected to the inner wall of the fixing hole 311 first contacts the stud 21. As the stud 21 slowly extends into the fixing hole 311, the stud 21 slowly contacts the elastic protrusion 312. The stud 21 presses the elastic protrusion 312 toward the inner wall of the fixing hole 311, and the elastic protrusion 312 provides a reaction force to fix the stud 21 in the fixing hole 311.

[0045] When installing the fixing bracket 3, align the fixing hole 311 of the fixing bracket 3 with the stud 21, and press the fixing bracket 3 downwards so that the stud 21 is installed into the fixing hole 311. With the cooperation of the elastic protrusion 312 and the stud 21, the stud 21 and the elastic protrusion 312 can be locked together. Through the cooperation of the elastic protrusion 312 and the stud 21 in the fixing hole 311, the installation of the fixing bracket 3 is simple, and the space occupied when installing the fixing bracket 3 is small, and it is not easy to interfere with other components.

[0046] The outer surface of the stud 21 has a thread 211. When the elastic protrusion 312 contacts the thread 211, the friction between the elastic protrusion 312 and the stud 21 can be increased, thereby further increasing the ability of the elastic protrusion 312 to restrict the installation position of the stud 21.

[0047] In the axial direction of the fixing hole 311, the fixing hole 311 includes a first end and a second end opposite to each other. The fixing bracket 3 has an installation direction. In the installation direction, the first end and the second end are first installed towards the stud 21. One end of the elastic protrusion 312 is connected to the first end of the inner wall of the fixing hole 311, and the other end of the elastic protrusion 312 is inclined towards the second end.

[0048] Reference Figures 1-3 In one possible implementation of this application, multiple fixing holes 311 are provided, and the number of studs 21 is equal to and corresponds one-to-one with the number of fixing holes 311, which can prevent the fixing bracket 3 from rotating relative to the studs 21 and causing the position of the fixing bracket 3 to change.

[0049] Multiple studs 21 and multiple fixing holes 311 are matched to each other, which can further increase the connection strength between the studs 21 and the fixing holes 311, thereby increasing the stability and firmness of fixing the bracket 3 to the studs 21.

[0050] When the vehicle is in motion, it may vibrate. By using multiple fixing holes 311 and multiple studs 21, the fixing bracket 3 can be more securely installed on the vehicle body 10, reducing the risk of loosening or falling off due to vibration or other external forces during vehicle operation.

[0051] For example, the fixed bracket 3 is a fixed block, and multiple fixing holes 311 are spaced apart along the width or length of the fixed block.

[0052] For example, there may be two or three fixing holes 311, and correspondingly, there may be two or three studs 21.

[0053] Reference Figures 2-3 In one possible implementation of this application, the stud 21 has a threaded groove 212, and the end of the elastic protrusion 312 is engaged in the threaded groove 212. The groove wall of the threaded groove 212 can limit the end of the elastic protrusion 312, so that the elastic protrusion 312 is not easy to fall out of the threaded groove 212, thereby increasing the firmness of the fit between the elastic protrusion 312 and the stud 21.

[0054] When the fixing hole 311 on the fixing bracket 3 is fitted onto the stud 21, the elastic protrusion 312 inside the fixing hole 311 undergoes a certain deformation due to its own elasticity and tilt setting, so that its end can be inserted into the threaded groove 212 on the stud 21, which improves the convenience of installation and also ensures that the fixing bracket 3 is firmly locked on the stud 21, reducing the risk of loosening or falling off due to vibration or other external forces.

[0055] Reference Figures 1-3In one possible implementation of this application, the threaded groove 212 has a first side and a second side disposed opposite to each other in the axial direction of the fixing hole 311, with an included angle of A between the first side and the second side. The end of the elastic protrusion 312 facing the center of the fixing hole 311 has a third side 3121 and a fourth side. The third side 3121 is disposed opposite to the first side, and the fourth side is disposed opposite to the second side. The included angle between the third side 3121 and the fourth side is B, satisfying A≥B.

[0056] The angle between the first and second sides is greater than or equal to the angle between the third and fourth sides, so that the end of the elastic protrusion 312 facing the center of the fixing hole 311 can extend into the threaded groove 212. When the end of the elastic protrusion 312 extends into the threaded groove 212, the elastic protrusion 312 can be wrapped or clamped by the threaded groove 212, thereby increasing the mechanical engagement effect between the two, preventing loosening, and resisting vibrations or external forces from the axial or radial direction.

[0057] For example, the angle between the first side and the second side can be 55° or 60°, and the angle between the third side 3121 and the fourth side can be 50° or 55°.

[0058] Reference Figure 1 , Figure 3 In one possible implementation of this application, the inner wall of the fixing hole 311 is connected with a plurality of ribs 313. The ribs 313 extend along the axial direction of the fixing hole 311. The plurality of ribs 313 are arranged at intervals along the inner wall of the fixing hole 311, and the ribs 313 and the elastic protrusions 312 are arranged alternately. On the inner wall of the fixing hole 311, an elastic protrusion 312 is arranged between two adjacent ribs 313, and a rib 313 is arranged between two adjacent elastic protrusions 312.

[0059] Rib 313 can increase the overall rigidity and resistance to deformation of fixing hole 311. When stud 21 is engaged with elastic protrusion 312 and elastic protrusion 312 deforms, rib 313 and stud 21 can be interference fit. Rib 313 can effectively prevent the stud 21 from falling out of fixing hole 311 due to deformation of elastic protrusion 312.

[0060] For example, the external thread 211 of the stud 21 does not extend to the end of the stud 21, so that the diameter of the end of the stud 21 is smaller than the diameter of other parts of the stud 21. When the stud 21 is inserted into the fixing hole 311, the smaller diameter of the end of the stud 21 makes it easier for the stud 21 to be inserted into the fixing hole 311, thereby reducing the force required to install the fixing bracket 3 onto the stud 21.

[0061] Reference Figure 1, Figure 3 In one possible implementation of this application, the fixing bracket 3 is a fixing block. When the mounting bracket is installed on the first fixing member 2, the fixing bracket 3 easily abuts against the vehicle body 10, and the vehicle body 10 can provide support for the fixing bracket 3. The fixing block has a cavity 314, and the side wall of the fixing block has a snap-fit ​​hole 315 communicating with the cavity 314. The wire harness 4 is detachably connected to the snap-fit ​​hole 315, and the fixed end of the wire harness 4 can extend into the cavity 314 through the snap-fit ​​hole 315, which can provide an installation position for fixing the wire harness 4.

[0062] Reference Figure 1 , Figure 3 In one possible implementation of this application, multiple snap-fit ​​holes 315 are provided, each snap-fit ​​hole 315 can be snapped with a wire harness 4, and multiple snap-fit ​​holes 315 can fix multiple wire harnesses 4. The multiple snap-fit ​​holes 315 can be fixed on different side walls of the fixing block. When fixing the wire harness 4, the direction or arrangement of the wire harness 4 is fixed, and the wire harness 4 can be fixed into the corresponding snap-fit ​​hole 315, which increases the flexibility of wiring.

[0063] Secondly, embodiments of this application provide a vehicle, including: a fixing component 20.

[0064] The vehicle provided in this application embodiment includes the stabilizer bar assembly provided in any of the above-mentioned embodiments, and therefore has the same technical effect. That is, the first fixing member 2 is pre-installed on the body 10, and the wiring harness 4 is installed on the first fixing member 2 through the fixing bracket 3. This not only improves the reliability and tightness of the installation between the first fixing member 2 and the body 10, and improves the waterproof performance, but the fixing component 20 can also provide a reliable fixing point for the wiring harness 4.

[0065] Reference Figure 1 , Figure 3 In one possible implementation of this application, the vehicle further includes: a wiring harness 4, which has a snap-fit ​​protrusion detachably connected to the fixed bracket 3, and the end of the wiring harness 4 may also be provided with a wiring harness terminal 41, which is also provided with a snap-fit ​​protrusion detachably connected to the fixed bracket 3; specifically, the snap-fit ​​protrusion of the wiring harness 4 snaps into the snap-fit ​​hole 315 of the fixed bracket.

[0066] For example, the snap-fit ​​protrusion has a guide surface on the side facing the fixed bracket 3 to guide the snap-fit ​​protrusion into the snap-fit ​​hole 315 of the fixed bracket 3. When it is necessary to remove the wire harness 4, the two ends of the snap-fit ​​protrusion are pressed to deform the snap-fit ​​protrusion towards the snap-fit ​​hole 315, so that the snap-fit ​​protrusion is disengaged from the snap-fit ​​hole 315, and the wire harness 4 is removed from the fixed bracket 3.

[0067] 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.
