Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to a wiring harness fixing mechanism and an automobile. Background Technology

[0002] When routing automotive wiring harnesses, it is necessary to plan and determine the layout path, trajectory, and fixing positions of the wiring harness on the vehicle body. Existing automotive wiring harnesses are fixed to the vehicle using clips, meaning multiple fixing points are set on the vehicle. The wiring harness is fixed with corresponding clips according to the preset spacing between these fixing points at the factory. However, due to dimensional tolerances in the wiring harness manufacturing process, and also tolerances in the spacing between adjacent fixing points, the dimensions of the two cannot be precisely matched.

[0003] The aforementioned problems can cause tension between the wiring harness and the clips, leading to assembly difficulties, inaccurate installation, and even unnatural arching deformation of the wiring harness, resulting in unnecessary contact and interference with surrounding components. This seriously affects the overall assembly quality of the vehicle and the service life of the wiring harness. Summary of the Invention

[0004] (I) The technical problem to be solved by the present invention is that during the installation of existing automotive wiring harnesses, there is a pulling between the wiring harness and the snap-fit ​​structure, which makes it difficult to assemble the wiring harness, make it difficult to install it accurately, and may even cause the wiring harness to have unnatural arching deformation, which in turn causes undue contact and interference with its surrounding components, seriously affecting the assembly quality of the whole vehicle and the service life of the wiring harness.

[0005] (II) Technical Solution To address the aforementioned technical problems, embodiments of the present invention provide a wiring harness fixing mechanism for automobiles, comprising a cable tie assembly, a limiting assembly, a sliding assembly, and a fixing assembly for connecting to the automobile; The cable tie assembly includes a cable tie and a cable tie holder, wherein the cable tie and the cable tie holder cooperate to secure the wire harness; The fixing component is connected to one side of the cable tie holder, and the cable tie holder slides relative to the fixing component in a direction parallel to the cross-section of the cable tie holder via the sliding component; The limiting component is used to fix the cable tie holder and the fixing component to restrict the cable tie holder from sliding relative to the fixing component.

[0006] Furthermore, the sliding component includes a slidingly engaged slider and a sliding groove; One of the cable tie holder and the fixing assembly is provided with the slider, and the other is provided with the groove.

[0007] Furthermore, the fixing component includes a fixing block, on which the groove is formed, and the cable tie seat has the slider on the side facing the fixing block.

[0008] Furthermore, the fixing component also includes a connecting pin, which includes a pin body and a pin head; One end of the nail body is connected to the nail head, and the other end is used to connect to the vehicle. The nail head is connected to the fixing block on the other side of the nail body, and the fixing block has the groove formed on the side away from the nail head.

[0009] Furthermore, one end of the slide groove is provided with an opening, through which the slider enters the slide groove; The maximum width of the slider along its own height direction is greater than the width of the groove opening.

[0010] Furthermore, the cross-section of the chute along its height direction is trapezoidal, and the width of the chute increases from top to bottom along its height direction. The slider has a set of outer wall surfaces along its width direction that are in contact with the corresponding inner wall surface of the groove.

[0011] Furthermore, the limiting component includes serrations and elastic locking teeth; Multiple saw teeth are continuously arranged on the inner bottom wall of the slide along the length direction of the slide, and a limiting groove is formed between two adjacent saw teeth; The outer bottom wall of the slider is provided with the elastic locking teeth, and the projection portions of the elastic locking teeth and the saw teeth along the length direction of the slide groove overlap; When the elastic locking teeth move with the slider, they can be inserted into or removed from the limiting groove. When the slider stops, the elastic locking teeth cooperate with the limiting groove to restrict the relative sliding between the slider and the groove.

[0012] Furthermore, a limiting spring is provided at the opening of the slide groove, one end of which is connected to the inner wall of the slide groove, and the other end extends toward the opposite side of the slide groove. The distance between the two limiting springs that are opposite each other along the width direction of the groove is less than the width of the slider at the corresponding position of the slider, and the limiting springs can undergo elastic deformation.

[0013] Furthermore, the cable tie holder is a quadrangular prism, and the interior of the cable tie holder forms a cavity. The cable tie holder has through holes that communicate with the cavity on its circumferential sidewalls. Two opposite through holes communicate with the cavity to form a wire passage.

[0014] An embodiment of the present invention also provides an automobile, including a vehicle body and a wiring harness. The vehicle body sheet metal has a fixing hole, and a wiring harness fixing mechanism cooperates with the fixing hole to assemble the wiring harness onto the vehicle body sheet metal. The wiring harness fixing mechanism is the wiring harness fixing mechanism described above.

[0015] The beneficial effects of this invention are: This invention provides a wire harness fixing mechanism, including a cable tie assembly, a limiting assembly, a sliding assembly, and a fixing component for connection with a vehicle. The cable tie assembly includes a cable tie and a cable tie seat, which cooperate to fix the wire harness. The cable tie seat is pressed into a pre-set fixing hole in the vehicle's body sheet metal by a fixing component connected to one side of it. The cable tie seat slides relative to the fixing component along a direction parallel to the cross-section of the cable tie seat through the sliding assembly. This allows for effective absorption and compensation of the length deviation between the wire harness and the pre-set fixing hole in the sheet metal during wire harness assembly, preventing pulling, arching deformation, or interference with surrounding parts during assembly. This reduces the difficulty of wire harness assembly, improves assembly efficiency, and prevents the wire harness from arching and deforming, thus preventing interference with surrounding parts. After assembly, the limiting assembly fixes the cable tie seat and the fixing component to limit relative sliding, significantly ensuring the service life and assembly quality of the wire harness.

[0016] The present invention provides an automobile comprising the aforementioned wiring harness fixing mechanism, which inherits all the beneficial effects of the wiring harness fixing mechanism. By fixing the wiring harness with cable ties and cable tie seats, during the assembly of the wiring harness, the sliding adjustment of the cable tie seats and fixing components eliminates the length deviation between the corresponding segments of the wiring harness and the fixing holes, so that the wiring harness can be arranged smoothly without pulling, arching, or interference with surrounding parts. This significantly improves the assembly efficiency and quality of the vehicle wiring harness, avoids wiring harness interference and wear, improves the reliability and safety of the vehicle's electrical system, and also reduces after-sales maintenance costs.

Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0023] Example 1 like Figures 1 to 11 As shown, the present invention provides a wire harness fixing mechanism for automobiles, including a cable tie assembly 100, a limiting assembly, a sliding assembly, and a fixing assembly 200 for connecting to the automobile. The cable tie assembly 100 includes a cable tie 101 and a cable tie seat 102, wherein the cable tie 101 and the cable tie seat 102 cooperate to fix the wire harness 300. The fixing component 200 is connected to one side of the cable tie holder 102, and the cable tie holder 102 slides relative to the fixing component 200 in a direction parallel to the cross-section of the cable tie holder 102 via the sliding component; The limiting component is used to fix the cable tie holder 102 and the fixing component 200 to limit the sliding of the cable tie holder 102 relative to the fixing component 200.

[0024] In this embodiment, the wire harness fixing mechanism includes a cable tie assembly 100, a limiting assembly, a sliding assembly, and a fixing member for connection with a vehicle. The cable tie assembly 100 includes a cable tie 101 and a cable tie holder 102, which cooperate to fix the wire harness 300. The cable tie holder 102 is pressed into a pre-set fixing hole in the vehicle body sheet metal 600 by a fixing assembly 200 connected to one side of it. The cable tie holder 102 slides relative to the fixing assembly 200 in a direction parallel to the cross-section of the cable tie holder 102 via the sliding assembly, thereby enabling the assembly of the wire harness 300. During the process, the sliding adjustment effectively absorbs and compensates for the length deviation between the wire harness 300 and the pre-set fixing holes in the sheet metal, avoiding the wire harness 300 from being pulled, arched, deformed, or even interfering with the surrounding parts during assembly. This reduces the difficulty of assembling the wire harness 300, improves assembly efficiency, and prevents the wire harness 300 from arching and deforming and interfering with the surrounding parts. After assembly, the cable tie seat 102 and the fixing component 200 are fixed by the limiting component to limit the relative sliding between the two, significantly ensuring the service life and assembly quality of the wire harness 300.

[0025] In this process, when the wire harness 300 leaves the factory, the cable ties 101 and cable tie seats 102 are fixed at the corresponding positions on the wire harness 300. At the same time, the excess cable ties 101 are cut off to complete the binding and fixing of the wire harness 300. Meanwhile, the car body sheet metal 600 will have corresponding fixing holes for installing the fixing components 200 during the production process. During assembly, the fixing components 200 are directly inserted into the fixing holes, and the sliding components are used to slide and adjust the fixing components 200 and the cable tie seats 102. This allows the wire harness 300 to be laid according to the preset path and can effectively absorb the length deviation caused by production and assembly.

[0026] According to one embodiment provided by the present invention, such as Figure 1 As shown, the sliding assembly includes a slider 400 and a groove 401 that are in sliding engagement; One of the cable tie holder 102 and the fixing assembly 200 is provided with a slider 400, and the other is provided with a groove 401.

[0027] In this embodiment, the cable tie holder 102 and the fixing component 200 are connected by a split sliding fit structure, which effectively solves the problem of mismatch between the segment size of the wire harness 300 and the size of the fixing hole in the vehicle body caused by the manufacturing tolerance of the wire harness 300 itself. This eliminates the difficulty in installing the wire harness 300 and solves the problem of bulging interference caused by size mismatch.

[0028] Optionally, the top of the fixing component 200 is provided with a sliding groove 401, and the bottom of the cable tie holder 102 is provided with a slider 400; or, the top of the fixing component 200 is provided with a slider 400, and the bottom of the cable tie holder 102 is provided with a sliding groove 401. Both of these configurations do not depart from the design concept of the present invention and should fall within the protection scope of the present invention. In use, the appropriate configuration can be selected based on different vehicle models, usage conditions, and needs. Since the adjustment principles and specific structures of the two schemes are the same, this embodiment will use the example of the fixing component 200 having a sliding groove 401 at the top and the cable tie holder 102 having a slider 400 at the bottom for illustrative purposes.

[0029] According to one embodiment provided by the present invention, such as Figure 1 As shown, the fixing component 200 includes a fixing block 201, on which a groove 401 is formed, and a slider 400 is provided on the side of the cable tie seat 102 facing the fixing block 201.

[0030] In this embodiment, specifically, the fixing component 200 includes a fixing block 201 with a groove 401 formed on its top along its own length direction. The cable tie holder 102 is provided with a slider 400 and is located on the side facing the fixing block 201. The groove 401 protrudes from the fixing hole preset in the body sheet metal 600. The groove 401 is generally elongated. During assembly, the slider 400 can slide along the extension direction of the groove 401. The relative position of the cable tie holder 102 and the fixing block 201 can be adjusted through the sliding cooperation between the two.

[0031] Optionally, the length of the slide 401 shall not exceed 20 mm. However, depending on different vehicle models and different usage conditions and scenarios, the specific lengths of the slide 401 and the slider 400 are not limited and can be set by the user to meet the usage requirements. The purpose of these settings is to deviate from the design concept of this invention and should fall within the protection scope of this invention.

[0032] The fixing block 201 and the cable tie seat 102 are guided and stabilized by the slider 400 and the slide groove 401, and slide smoothly. The adjustment of their relative positions is relatively stable. At the same time, the assembly cost between the two is low and will not increase the labor intensity. The length of the slider 400 needs to be significantly smaller than the length of the slide groove 401 to allow for sufficient adjustment stroke. It can accommodate a large range of deviations in the segment length of the wire harness 300 and the spacing of the fixing holes, thus ensuring the overall applicability of the wire harness fixing mechanism provided in this embodiment.

[0033] According to one embodiment provided by the present invention, such as Figure 1 As shown, the fixing component 200 also includes a connecting pin 202, which includes a pin body 203 and a pin head 204; One end of the nail body 203 is connected to the nail head 204, and the other end is used to connect to the car. The nail head 204 is connected to a fixing block 201 on the other side of the nail body 203. A groove 401 is formed on the side of the fixing block 201 away from the nail head 204.

[0034] In this embodiment, optionally, if the fixing hole is set as a smooth inner wall surface, the side wall of the nail body 203 is symmetrically provided with an elastic barb structure. After being pressed into the fixing hole, the barb clamps the back of the sheet metal to prevent the nail body 203 from coming out of the fixing hole. If the fixing hole is set as a threaded hole, the side wall of the nail body 203 is provided with an external thread that can engage with the thread of the fixing hole. The two are fixed by thread engagement to prevent the nail body 203 from coming out of the fixing hole. The fixing block 201 is located on the top of the nail head 204, that is, on the other side relative to the nail body 203. A groove 401 is formed on the side of the fixing block 201 away from the nail head 204. The nail head 204 is a sheet-like structure. Preferably, it can have a certain curvature. The bottom surface of the nail head 204 can completely cover the fixing hole on the body sheet metal 600.

[0035] Correspondingly, the nail body 203 of the connecting nail 202 can be flexibly configured into different sizes of round or oblong shapes according to the specific opening of the body sheet metal 600 so as to be snapped onto the fixing holes of different forms on the body sheet metal 600. In practical applications, the nail body 203 of the connecting nail 202 in the wiring harness fixing mechanism provided in this embodiment can be adapted to the two common opening forms of the body sheet metal 600, namely round holes and oblong holes, which greatly enhances its versatility. Of course, if the opening form of the body sheet metal 600 is other shapes, the shape of the nail body 203 can be changed accordingly, without changing the specific shape of the rest of the structure.

[0036] After assembly, the nail body 203 is firmly engaged with the fixing hole, and will not loosen or fall off after installation; the nail head 204 covers the fixing hole, which serves to prevent dust and water and protect the sheet metal; the overall support is stable and the structure has high strength.

[0037] Optionally, the nail body 203, nail head 204, and fixing block 201 can be an integrally molded structure, made of plastic material and injection molded, which is convenient for mass production. Alternatively, the nail body 203 and nail head 204 can be an integrally molded structure, while the fixing block 201 is a separately molded structure, all made of plastic material and injection molded, and assembled by adhesive or other fixing methods after molding. Or, the nail body 203, nail head 204, and fixing block 201 can all be separately molded structures, all made of plastic material and injection molded, and assembled by adhesive or other fixing methods after molding. All of the above methods do not depart from the design concept of the present invention and should fall within the protection scope of the present invention.

[0038] According to one embodiment provided by the present invention, such as Figure 1 As shown, one end of the slide groove 401 is provided with an opening, and the slider 400 enters the slide groove 401 through the opening; The maximum width of slider 400 along its own height direction is greater than the width of the groove opening of slide 401.

[0039] In this embodiment, one end of the groove 401 is provided with an opening for the slider 400 to enter. During assembly, the connecting nail 202 is inserted into the fixing hole of the body sheet metal 600, and the fixing block 201 is located on the upper surface of the nail head 204. The slider 400 enters the groove 401 opened by the fixing block 201 through the opening. Since the length of the slider 400 is less than the length of the groove 401, the slider 400 can slide along the extension direction of the groove 401 to change the relative position of the slider 400 in the groove 401. This allows the cable tie seat 102 to slide relative to the fixing block 201 to achieve sliding adjustment and change the relative position relationship between the two.

[0040] The separate structure of the fixing block 201 and the cable tie holder 102 allows for assembly by first inserting the fixing component 200 into the fixing hole. After both are stable, the slider 400 at the bottom of the cable tie holder 102 is inserted into the groove 401 through the opening. The slider 400 can reciprocate along the extension direction of the groove 401, changing the relative position of the cable tie holder 102 and the fixing block 201. This enables continuous adjustment of the fixing position of the wire harness 300 until the usage requirements are met. In other words, during assembly, even if there is a significant deviation between the spacing between two adjacent fixing holes preset in the body sheet metal 600 and the corresponding segment length of the wire harness 300, the sliding fit between the fixing block 201 and the cable tie holder 102 can absorb and compensate for this deviation, ultimately completing the assembly of the wire harness 300. This allows the wire harness 300 to continue to be laid out along the preset path without causing arching deformation or interference with surrounding parts.

[0041] Since the maximum width of the slider 400 along its own height direction is greater than the width of the groove 401, it can be ensured that the slider 400 will not come out of the groove 401 along its height direction during the sliding process or after assembly.

[0042] According to one embodiment provided by the present invention, such as Figure 1 As shown, the cross-section of the slide 401 along its height direction is trapezoidal, and the width of the slide 401 increases from top to bottom along its height direction. A set of outer wall surfaces of slider 400 along its own width direction are in contact with the corresponding inner wall surfaces of slide groove 401.

[0043] In this embodiment, preferably, the cross-section of the slide groove 401 along its height direction is trapezoidal. To ensure that the slider 400 will not dislodge from the slide groove 401 due to vibrations during vehicle operation after assembly, the width of the slide groove 401 is designed to increase from top to bottom along its height direction. The cross-sectional shape of the slider 400 is adapted to the slide groove 401, meaning that after the slider 400 enters the slide groove 401, a set of outer sidewalls of the slider 400 along its width direction fits against the corresponding inner sidewalls of the slide groove 401. After the slider 400 is embedded in the slide groove 401, its sidewalls fit against the inner wall of the slide groove 401. Due to the aforementioned trapezoidal design, the slider 400 can only slide along the length direction of the slide groove 401 and cannot move up and down along the height direction of the slide groove 401, ensuring the stability of the slider 400's sliding.

[0044] The trapezoidal cross-section design of the groove 401 and slider 400 effectively constrains the vertical movement of the slider 400, resulting in stronger guidance and stability. The wider bottom of the groove 401 provides higher structural strength, effectively improving the stability of the adjustment process. Furthermore, the simple shape of these components does not increase mold setup costs; the injection molding process is simple and suitable for mass production.

[0045] According to one embodiment provided by the present invention, such as Figure 1 As shown, the limiting component includes a serration 500 and a resilient locking tooth 501; Multiple serrations 500 are continuously arranged on the inner bottom wall of the slide groove 401 along the length direction of the slide groove 401, and a limiting groove is formed between two adjacent serrations 500. The outer bottom wall of the slider 400 is provided with elastic locking teeth 501, and the projection portions of the elastic locking teeth 501 and the saw teeth 500 along the length direction of the slide groove 401 overlap. When the elastic locking tooth 501 moves with the slider 400, it can be inserted into or removed from the limiting groove. When the slider 400 stops, the elastic locking tooth 501 cooperates with the limiting groove to restrict the relative sliding between the slider 400 and the groove 401.

[0046] In this embodiment, the bottom wall of the slide groove 401 is provided with a plurality of serrations 500 arranged sequentially and connected along its own length direction. The bottom of the slider 400 is integrally formed with elastic locking teeth 501. The elastic locking teeth 501 can elastically deform as the slider 400 slides and engage with the limiting groove formed between two adjacent serrations 500 to achieve positioning. That is, a limiting groove is formed between every two adjacent serrations 500. The shape of the elastic locking teeth 501 is adapted to the limiting groove. When the slider 400 slides, the positional relationship between the slider 400 and the slide groove is relatively fixed by the engagement between the elastic locking teeth 501 and the limiting groove. Preferably, the elastic locking tooth 501 has a certain elasticity. Since it is integrally formed on the bottom of the slider 400, the elastic locking tooth 501 can move synchronously with the slider 400. During the assembly process, the slider 400 can be slid by external force. When the position of the slider 400 is fixed, the elastic locking tooth 501 will be locked in the limiting groove and will not slide easily, thereby ensuring the stability of the wire harness 300 after it is fixed.

[0047] In other words, since the elastic locking tooth 501 can move synchronously with the slider 400, when the pushing force on the slider 400 reaches the threshold, the contact force between the elastic locking tooth 501 and the sawtooth 500 can cause the elastic locking tooth 501 to undergo elastic deformation. As a result, the elastic locking tooth 501 moves from one limiting groove to another limiting groove with the movement of the slider 400. If the slider 400 is adjusted and slid to the target position and is no longer pushed and is in a stopped state, the pushing force caused by vibration and other working conditions during use cannot cause the elastic locking tooth 501 to undergo elastic deformation. Therefore, the elastic locking tooth 501 can stably engage with the limiting groove.

[0048] Of course, the specific number of saw teeth 500 is not specifically limited here. Depending on the different vehicle models, it can be set according to the actual use and usage scenarios. Preferably, the number of elastic locking teeth 501 is set to one. Of course, in order to ensure its stability after adjustment, it can also be set to two or more. The purpose of these settings is to deviate from the design concept of this invention and should fall within the protection scope of this invention.

[0049] During assembly, the elastic locking teeth 501 slide over the saw teeth 500 during adjustment and automatically lock into place upon reaching the correct position, eliminating the need for additional locking components. Multi-level positioning is achieved through the interaction of the saw teeth 500 and the elastic locking teeth 501, ensuring no slippage or springback after adjustment; repeated fine-tuning is possible to meet the needs of multiple corrections during assembly; and reliable positioning is maintained even under vehicle vibration conditions. The interaction between the elastic locking teeth 501 and the saw teeth 500 effectively locks and limits movement. After the cable tie holder 102 and the rivet holder are assembled, they can move freely within a preset size range, and the interaction between the elastic locking teeth 501 and the saw teeth 500 effectively restrains the swaying of the wire harness 300.

[0050] Of course, the limiting component may also include limiting holes and limiting pins. That is, at this time, the outer bottom wall of the slider 400 and the inner bottom wall of the slide groove 401 are both smooth planes, and the two can only slide together. At this time, limiting holes are opened on a set of opposite side walls of the slide groove 401. Preferably, the limiting holes are symmetrically opened, and at least one set is provided. The side wall of the slider 400 is provided with a corresponding mating screw hole. After the slider 400 is adjusted to offset the deviation between the wire harness 300 and the fixing hole, the limiting pin is inserted into the limiting hole until the end of the limiting pin is inserted into the mating screw hole corresponding to the side wall of the slider 400. That is, the end of the limiting pin is provided with an external thread that can be threaded with the mating screw hole. The limiting pin restricts the slider 400 from sliding again after adjustment and fitting, thereby effectively constraining the shaking of the wire harness 300.

[0051] According to one embodiment provided by the present invention, such as Figure 1 As shown, a limiting spring piece 402 is provided at the opening of the slide groove 401. One end of the limiting spring piece 402 is connected to the inner wall of the slide groove 401, and the other end extends toward the opposite side of the slide groove 401. The distance between the two limiting springs 402 opposite each other along the width direction of the slide groove 401 is less than the width of the slider 400 corresponding to the slider 400, and the limiting springs 402 can undergo elastic deformation.

[0052] In this embodiment, limiting spring pieces 402 are respectively provided on the inner sidewall of the slide groove 401 at the opening. Preferably, the limiting spring pieces 402 on both sides are symmetrically arranged and extend towards each other. After the slider 400 is inserted into the slide groove 401 along the opening, the limiting spring pieces 402 are located on the rear side of the slider 400 in the direction of entry, preventing the slider 400 from falling out of the slide groove 401 due to vibration during subsequent use or transportation.

[0053] In other words, one end of the limiting spring 402 is connected to the inner wall of the slide groove 401, and the other end can elastically deform and swing relative to the inner wall under external force. When the slider 400 is inserted into the slide groove 401 through the opening, a pushing force is manually applied so that the slider 400 can push the limiting spring 402 into the slide groove 401. After assembly, during subsequent use or transportation, due to insufficient pushing force, the slider 400 can push the limiting spring 402 in the opposite direction. The limiting spring 402 will not elastically deform and will always be in the effect of sealing the opening. Therefore, it can be ensured that the slider 400 will not exit the slide groove 401 through the opening. This ensures that the wire harness fixing mechanism provided in this embodiment will not separate from the clip seat and the cable tie seat 102 during use and transportation after assembly, further ensuring the overall stability of the two.

[0054] Among them, the limiting spring 402 effectively prevents the slider 400 from coming out of the opening of the slide groove 401 during assembly or use, thus improving structural reliability; it does not hinder the horizontal sliding of the slider 400 and does not affect the adjustment function; the structure is compact and suitable for small installation space inside the vehicle.

[0055] Furthermore, preferably, the limiting spring 402 is triangular in shape, wherein one side of the limiting spring 402 is smoothly connected to the inner wall of the slide groove 401, and the other two sides are inclined towards the inside of the slide groove 401. When the slider 400 is inserted through the opening, the assembly resistance is small, and it can slide in smoothly. Accordingly, the triangular limiting spring 402 has a stable structure, uniform force distribution, and strong impact resistance; it facilitates the assembly and insertion of the slider 400, improving assembly efficiency; it also ensures smooth demolding and a high production yield.

[0056] According to one embodiment provided by the present invention, such as Figure 1 As shown, the cable tie holder 102 is a quadrangular prism with a cavity inside. The cable tie holder 102 has through holes that communicate with the cavity on its circumferential sidewalls. Two opposite through holes are connected through the cavity to form a cable passage.

[0057] In this embodiment, the cable tie holder 102 and the slider 400 are integrally formed. The cable tie holder 102 is a four-sided prism frame structure, preferably a cube or cuboid structure. The cable tie 101 can pass through the cable tie holder 102 to tightly secure the wire harness 300. In other words, the cable tie holder 102 provides dedicated support for fixing the wire harness 300, ensuring standardized and secure fixing; it is integrally formed with the slider 400, resulting in a compact and reliable structure; it is compatible with universal standard cable ties 101, offering strong versatility and facilitating vehicle assembly and after-sales maintenance.

[0058] Specifically, the cable tie holder 102 has an internal cavity, and through holes are formed on its circumferential sidewalls. Two opposite through holes in each group connect through the cavity to form a wire passage channel, allowing the cable tie 101 to pass smoothly through. Alternatively, the cable tie holder 102 can be designed as a hollow structure, with all surfaces interconnected. This allows observation of the cable tie 101's passage from the top, while also reducing the overall weight of the wiring harness fixing mechanism provided in this embodiment, meeting the design requirements for vehicle lightweighting. This design does not deviate from the original concept and should be within the scope of protection of this invention.

[0059] The cable tie holder 102 is designed with a cross-shaped path in two directions, allowing the cable ties 101 to be assembled in both directions to bundle and secure the wire harness 300, thereby meeting the different routing requirements of the wire harness 300, such as... Figure 9 and Figure 10 As shown, cable ties 101 can be inserted through the corresponding through holes according to the arrangement direction of the wire harness 300, thereby achieving multi-directional fixation of the wire harness 300. The multi-directional through holes improve the fixation flexibility and adapt to different arrangements of the wire harness 300; the cable ties 101 are easy to insert, shortening the assembly time; the cable ties 101 are evenly stressed, avoiding local pressure damage to the wire harness 300.

[0060] In summary, using the wiring harness fixing mechanism provided in this embodiment, one of two adjacent fixing points on the body sheet metal 600 can use a conventional fixing clip, while the other can use the wiring harness fixing mechanism provided in this embodiment, or both fixing points can use the wiring harness fixing mechanism provided in this embodiment. For example, if one of two adjacent fixing points on the body sheet metal 600 uses a conventional fixing clip and the other uses the wiring harness fixing mechanism provided in this embodiment, then... Figure 11As shown, if a conventional fastener is fixed to the fixing hole of the body sheet metal 600, and a conventional fastener is also used in another fixing hole, the following problem will often be encountered during the assembly process: due to the manufacturing tolerance of the wire harness 300, especially when the main trunk of the wire harness 300 is too thick, the wire harness 300 after laying will cause the clip seat to be difficult to align with the fixing hole of the body sheet metal 600, resulting in assembly difficulties. Even if the fixing buckle is forced into the fixing hole, the wire harness 300 will arch due to the deviation in the segment size of the two fixing buckles, and will not follow the original design direction. This is very likely to cause interference with the surrounding environment in the compact vehicle body layout space. However, if the wire harness fixing mechanism provided in this embodiment is used in another fixing hole, the fixing block 201 and the cable tie seat 102 can slide relative to the fixing block 201 because the sliding adjustment cooperation between the sliding groove 401 and the slider 400 allows the cable tie seat 102 to slide relative to the fixing block 201. When it slides to match the hole spacing, it will be easier to align and install with the fixing hole of the vehicle body sheet metal. In addition, the limiting function generated by the cooperation between the elastic tooth 501 at the bottom of the slider 400 and the serration 500 at the bottom of the sliding groove 401, as well as the limiting effect of the limiting rib, ensures the stability of the cable tie seat 102 and the fixing block 201 after assembly, effectively avoiding the occurrence of shaking problems.

[0061] Example 2 The present invention provides an automobile, including a vehicle body and a wiring harness 300. The body sheet metal 600 of the vehicle body has a fixing hole. The wiring harness fixing mechanism cooperates with the fixing hole to assemble the wiring harness 300 onto the body sheet metal 600. The wiring harness fixing mechanism is the aforementioned wiring harness fixing mechanism.

[0062] In this embodiment, during the production process, the body sheet metal 600 of the automobile body will have pre-set fixing holes according to the assembly path of the wiring harness 300. The wiring harness fixing mechanism is fixed to the body sheet metal 600 through the fixing holes, and the wiring harness 300 is bound and fixed by the cooperation of the cable tie 101 and the cable tie seat 102 to ensure that the wiring harness 300 can be laid out completely according to the preset path.

[0063] The vehicle provided in this embodiment inherits all the beneficial effects of the wiring harness fixing mechanism. The wiring harness 300 is fixed by the cable tie 101 and the cable tie seat 102. When assembling the wiring harness 300, the sliding adjustment of the cable tie seat 102 and the fixing component 200 eliminates the length deviation between the corresponding segments of the wiring harness 300 and the fixing holes, so that the wiring harness 300 can be arranged smoothly without pulling, arching or interference with surrounding parts. This significantly improves the assembly efficiency and quality of the wiring harness 300 in the whole vehicle, avoids interference and wear of the wiring harness 300, improves the reliability and safety of the vehicle's electrical system, and can also reduce after-sales maintenance costs.

[0064] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
