[0002] In modern automobile manufacturing, automotive cable ties are important tools for managing and fixing the internal wiring harnesses of automobiles. The number of wiring harnesses inside an automobile is numerous and the layout is complex. Reasonably managing and fixing these wiring harnesses is crucial for ensuring the normal operation of the vehicle's electrical system and improving the safety and reliability of the vehicle. The automotive wiring harness fixing device needs to drill holes at relevant positions on the vehicle body in advance, install the wiring harness restraint structure on the connecting plate, fix the connecting plate to the vehicle body using screw connectors, and then use the wiring harness restraint structure to fix the wiring harness, so as to firmly fix the wiring harness on the vehicle body sheet metal or frame, thereby preventing the wiring harness from loosening or being damaged due to vibration during vehicle driving.

[0003] Existing automotive cable ties usually adopt a single-direction wiring harness restraint structure, which mainly includes a belt body and a seat body. The seat body is connected to the first end of the belt body and has a perforation. After one end of the belt body away from the seat body passes through the perforation, the wiring harness is tied in the perforation. This single-direction wiring harness restraint structure is difficult to adapt to the complex and changeable wiring harness layout requirements inside an automobile. Especially when it is necessary to fix wiring harnesses from different directions simultaneously, the existing cable tie structure often seems inadequate. Therefore, when fixing multi-directional wiring harnesses, existing automotive cable ties have the problem of insufficient flexibility and difficulty in meeting the requirements of multi-directional wiring harness restraint.

Detailed Embodiments

[0018] The following will combine the attached Figures 1 - 5 , and clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0019] Embodiment 1: The embodiment of the present application discloses an automotive wire harness tape 100 with a multi-strand structure. Refer to Figure 1 , the automotive wire harness tape 100 includes a base 1, a plurality of wire threading parts 2, and a plurality of wire harness tape bodies 3.

[0020] A connection groove is provided on the base 1 for mating connection with the external thread 201 of the automotive stud 200 ( Figure 1 not shown in the figure). In some embodiments, an internal thread may be provided on the inner side wall of the base 1 to achieve threaded connection with the external thread 201 of the automotive stud 200. In this embodiment, refer to Figure 2 , elastic locking teeth 4 are provided on the inner side wall of the base 1, and the elastic locking teeth 4 are used to engage with the external thread 201 of the automotive stud 200.

[0021] A plurality of wire threading parts 2 with perforations 21 in the middle are provided on the outer periphery of the base 1 along the circumferential direction. The number of wire threading parts 2 can be three, four, five, etc. Figure 2 Only two wire threading parts 2 are schematically shown in the figure. A plurality of wire harness tape bodies 3 correspond to the plurality of perforations 21 one by one and are threaded through the perforations 21 for binding the wire harness to the base 1. The excess parts of the wire harness tape bodies 3 are cut off; then the base 1 is installed on the automotive stud 200, and the connection groove is in mating connection with the external thread 201 of the automotive stud 200, so as to realize the fixation of multi-directional wire harnesses.

[0022] Compared with the threaded connection method, the elastic snap teeth 4 and the external thread 201 of the elastic snap connection can achieve rapid installation without the aid of external tools, greatly simplifying the assembly process, reducing the assembly time and labor costs. It is especially suitable for scenarios with high efficiency requirements in automobile manufacturing and can effectively improve production efficiency. Secondly, the connection method of the elastic snap teeth 4 has higher flexibility and adaptability. Due to its elastic characteristics, the elastic snap teeth 4 can automatically adapt to the external thread 201 of the stud. Even when there are slight deviations in the stud size, it can maintain a stable connection. This self-adaptive ability makes the cable tie more convenient during installation and reduces the risk of installation failure caused by thread mismatch. In addition, the elastic snap connection between the elastic snap teeth 4 and the external thread 201 can effectively resist vibration and impact during vehicle driving, ensuring the stability of the automotive cable tie 100.

[0023] The multi-cable structure in the automotive cable tie 100 breaks through the limitation of the traditional single-direction wire harness constraint, can simultaneously meet the fixing requirements of multi-direction wire harnesses, greatly improves the adaptability of the cable tie to complex wire harness layouts, and solves the problem of insufficient flexibility of the existing cable tie when fixing multi-direction wire harnesses.

[0024] Specifically, continue to refer to Figure 2 , a plurality of positioning strips 5 are arranged at intervals along the circumferential direction on the inner side wall of the base 1. The positioning strips 5 extend along the height direction of the base 1 and are used to abut against the external thread 201 of the automotive stud 200. The elastic snap teeth 4 are located between two adjacent positioning strips 5.

[0025] The setting of the positioning strips 5 makes a certain gap between the external thread 201 of the automotive stud 200 and the inner side wall of the base 1, providing a deformation space for the elastic snap teeth 4 and preventing the elastic snap teeth 4 from being overly deformed and affecting the snap connection with the external thread 201 of the automotive stud 200. The setting of the positioning strips 5 also provides precise positioning for the automotive stud 200, ensuring that the elastic snap teeth 4 can be accurately aligned when snap-connected to the external thread 201 of the automotive stud 200 and avoiding structural damage caused by local stress concentration of the elastic snap teeth 4 during the installation process.

[0026] Each wire threading part 2 extends away from the base 1 to form a wire protecting part 6. The wire protecting part 6 has an arc surface 61 adapted to the bundled wire harness after bundling, which can hold the wire harness bound by the wire tying belt joined into a loop, and the arc surface 61 of the wire protecting part 6 can closely fit the surface of the wire harness. The orientation of the arc surface 61 of the wire protecting part 6 can be specifically set according to the direction of the wire harness. In this embodiment, the arc surface 61 of the wire protecting part 6 faces in the direction opposite to the notch direction of the connecting groove. The wire protecting part 6 can provide a supporting effect for the wire harness, thus effectively preventing the wire harness from loosening or shifting due to vibration during vehicle driving, and avoiding the wire harness from being worn or scratched during the fixing process, reducing the risk of electrical faults that may be caused by the shaking of the wire harness, being beneficial to improving the service life and reliability of the wire harness, and ensuring its long-term stable operation under complex working conditions.

[0027] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 lies in: Referring to Figure 3 , the base 1 includes a base body 11 and a plurality of clamping parts 12. The base body 11 is formed by splicing two cylinders with semi-circular cross-sections. A connecting groove is formed through the middle of the base body 11. In this embodiment, for the convenience of operation, the two semi-circular cylinders are spliced in the form of a buckle. Align the two semi-circular cylinders and press them towards each other to splice them into a base body 11 with a circular cross-section.

[0028] Each clamping part 12 is provided with a clamping groove 12a. The side wall of the base body 11 is inserted into the clamping groove 12a. The plurality of clamping parts 12 are arranged circumferentially around the base body 11. The end of the clamping part 12 located outside the base body 11 is the outer end, and the end located in the connecting groove is the inner end. Among them, the wire threading part 2 is fixed to the outer end of the clamping part 12, and the elastic clamping teeth 4 are arranged at the inner end of the clamping part 12. The inner end and the outer end of the clamping part 12 are both set to be able to shorten in the height direction of the base body 11, so that the plurality of elastic clamping teeth 4 can be adapted to different thread layers of the external thread 201 of the automotive stud 200, and the height of the wire threading part 2 can also be adjusted.

[0029] In this embodiment, the inner end and the outer end of the clamping part 12 both form a one-way locking with a shortened length. Specifically, the clamping part 12 includes a U-shaped part 121 and two inwardly shrinking parts 122. Accommodating grooves are opened at both ends of the U-shaped part 121, and ratchet structures are provided on the inner side walls of the accommodating grooves. Elastic pawl structures that can elastically deform and are adapted to the ratchet structures are provided on the two inwardly shrinking parts 122, so as to realize the shortening of the length of the clamping part 12. This is an existing structure and will not be specifically described.

[0030] By adjusting the lengths of the clamping portions 12, the clamping portions 12 can be inserted into different positions on the side wall of the base body 11 according to the specific routing and layout requirements of the wire harness, so that the heights of the respective elastic teeth 4 are different, thereby engaging with different thread layers of the external thread 201 of the automotive stud 200. By adjusting the height of the wire threading portion 2, mutual interference caused by different routing directions of adjacent wire harnesses can be avoided.

[0031] For example, referring to Figure 4 and Figure 5 , Figure 4 in which the U-shaped portion 121 and one of the retracted portions 122 of some of the clamping portions 12 are hidden to show the specific position where the elastic teeth 4 engage with the external thread 201 of the automotive stud 200. In this embodiment, taking the elastic tooth A as a reference, in the clockwise direction along the base body 11, the more other elastic teeth 4 are closer to the elastic tooth A, the more the number of thread layers they differ from the reference, i.e., the elastic tooth A. Specifically, the number of thread layers that the elastic tooth A differs from the elastic tooth B is 5, the number of thread layers that the elastic tooth A differs from the elastic tooth C is 3, and the number of thread layers that the elastic tooth A differs from the elastic tooth D is 0.5 (defining one turn of the helix as one layer and half a turn as half a layer, and rounding up when the difference in the number of thread layers exceeds one layer). Since the wire threading portions 2 corresponding to the elastic tooth A and the elastic tooth D are located at opposite positions and the corresponding wire harness routings are parallel, even if the heights of the wire threading portions 2 corresponding to the elastic tooth A and the elastic tooth D differ slightly, it will not cause interference between the wire harnesses. Different elastic teeth 4 engage with different thread layers, which can achieve a more uniform force distribution, avoid stress concentration on the same thread layer, and ensure the stability of the wire harness after fixation; at the same time, the adjacent wire threading portions 2 can be placed at different heights, so that the adjacent wire harnesses are fixed at different heights, avoiding mutual interference caused by different wire harness routings. In a complex automotive interior environment, the wire harnesses may need to be arranged in different directions, and this structure can effectively prevent friction or collision between the wire harnesses, thereby reducing the risk of wire harness wear.

[0032] The clamping portion 12 can slide circumferentially along the base body 11. According to the routing of the wire harness to be tied, by moving the clamping portion 12, the wire threading portion 2 can be adapted to the routing of the wire harness to be tied. For example, the position of the elastic tooth A and the corresponding wire harness remains unchanged. When moving the elastic tooth B, if it is moved in the direction of the elastic tooth A, i.e., in the counterclockwise direction, the distance between the wire harness tied by the elastic tooth A and the wire harness tied by the elastic tooth B in the circumferential direction of the base body 11 becomes smaller, but the distance in the axial direction of the base body 11 increases. Therefore, when moving the elastic tooth B to a position where the distance from the elastic tooth A gradually becomes smaller, it will not cause interference between the two wire harnesses.

[0033] Further, the inner end of the clamping portion 12 is configured such that the force required to pull the elastic teeth 4 out of the gap between adjacent thread layers of the automotive stud 200 is greater than the force that causes the length of the inner end of the clamping portion 12 to shorten. That is, by pulling the clamping portion 12 outwards, the height of the elastic teeth 4 can be adjusted. After adjusting to the required height, there is a gap between the middle part of the U-shaped portion 121 and the base body 11. By pressing the U-shaped portion 121 downwards, since the force required for the retraction portion 122 to further insert into the U-shaped portion 121 and reduce the length of the clamping portion 12 is less than the force required to pull the elastic teeth 4 out of the gap between adjacent thread layers of the automotive stud 200, therefore, by pressing the U-shaped portion 121, the length of the clamping portion 12 can be reduced to fit the base body 11. At this time, the elastic teeth 4 still remain in the original thread layer.

[0034] The embodiment of the present application also provides a wire bundling method, which uses the above-mentioned automotive wire bundling belt 100 with a multi-wire bundling structure, and includes the following steps: Pass the wire bundling belt body 3 through the perforation 21, use different wire bundling belt bodies 3 to tie up the wire harnesses in different directions, and cut off the excess part of the wire bundling belt body 3; Install the base 1 on the automotive stud 200 so that the connection groove is in fit connection with the external thread 201 of the automotive stud 200.

[0035] The above two steps do not have a specific sequence. The wire harness can be tied to the base 1 first and then the base 1 is installed on the automotive stud 200; of course, it is also possible to install the base 1 on the automotive stud 200 first and then tie the wire harness to the base 1. The operation sequence is specifically selected according to the actual situation.

[0036] In one embodiment, installing the base 1 on the automotive stud 200 so that the connection groove is in fit connection with the external thread 201 of the automotive stud 200 includes the following steps: Adjust the length of each clamping portion 12. Specifically, by pressing the U-shaped portion 121 and the retraction portion 122, the degree to which the retraction portion 122 extends into the U-shaped portion 121 can be adjusted.

[0037] According to the directions of each wire harness, insert each clamping portion 12 on the side wall of the base body 11 so that the elastic teeth 4 at the inner ends of the respective clamping portions 12 are at different heights. Place the two semi-cylindrical bodies of the base body 11 on both sides of the automotive stud 200 and press them towards each other so that each elastic tooth 4 is engaged with a different thread layer of the external thread 201 of the automotive stud 200. Taking one elastic tooth 4 as a reference, along at least half of the circumference of the base body 11, the closer other elastic teeth 4 are to the reference, the more the number of thread layers they differ from the reference.

[0038] When installing the mounting base 1, by adjusting the length of the clamping portion 12, the elastic clamping teeth 4 are engaged with different thread layers of the external thread 201 of the automotive stud 200, which can achieve a more uniform force distribution, avoid stress concentration, and at the same time, the position of the clamping portion 12 can be adjusted according to the wiring harness routing to ensure the stability after the wiring harness is fixed, effectively prevent friction or collision between the wiring harnesses, reduce the wear risk, thereby improving the service life and reliability of the wiring harness, and ensuring its long-term stable operation under complex working conditions.

[0039] After each elastic clamping tooth 4 is engaged with different thread layers of the external thread 201 of the automotive stud 200, it further includes: sliding the clamping portion 12 along the circumferential direction of the base 1, adjusting the position of the clamping portion 12 according to the routing of the wiring harness tied by the harness band body 3, and pressing the clamping portion 12 to reduce the length of the inner end of the clamping portion 12 to fit the base 1.

[0040] After each elastic clamping tooth 4 is engaged with different thread layers of the external thread 201 of the automotive stud 200, by sliding the clamping portion 12 along the circumferential direction of the base 1 and adjusting the position of the clamping portion 12 according to the routing of the wiring harness tied by the harness band body 3, the layout and fixing effect of the wiring harness can be further optimized. This adjustment method enables the clamping portion 12 to move flexibly according to the actual routing of the wiring harness, ensuring a more reasonable distribution of the wiring harness on the base 1, avoiding mutual interference or extrusion caused by inconsistent wiring harness routing, thereby reducing the risk of wiring harness wear. At the same time, pressing the clamping portion 12 to reduce the length of its inner end to fit the base 1 further enhances the connection stability between the clamping portion 12 and the base 1, ensuring that the elastic clamping teeth 4 are more firmly and reliably engaged on the stud, not only improving the adaptability of the harness band to different wiring harness layouts, but also enhancing its stability and reliability under complex working conditions, effectively improving the flexibility and overall performance of the wiring harness fixing.

[0041] After each elastic clamping tooth 4 is engaged with different thread layers of the external thread 201 of the automotive stud 200, it further includes: after each elastic clamping tooth 4 is engaged with different thread layers of the external thread 201 of the automotive stud 200, it further includes: pulling out the clamping portion 12 outward, adjusting the elastic clamping teeth 4 to a suitable thread layer level according to the diameter of the wiring harness, and pressing the clamping portion 12 to reduce the length of the inner end of the clamping portion 12 to fit the base 1.

[0042] This adjustment method enables the elastic clamping teeth 4 to accurately adapt to wiring harnesses of different diameters, avoiding excessive extrusion of the wiring harness caused by improper clamping positions. At the same time, pressing the clamping portion 12 to reduce the length of its inner end further enhances the adaptability between the clamping portion 12 and the base 1, making the entire harness band structure more compact and stable, and improving the adaptability of the harness band to different wiring harness diameters.
