[0031] The following describes the preferred embodiments of the present disclosure with reference to the accompanying drawings of the specification. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. And without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0032] This embodiment provides a telescopic wire groove, as Figures 1 to 10 shown. Part of the wiring harness 10 passes through its interior and fixes the wiring harness 10 in the installation position. It includes an outer wire groove 1 and an inner wire groove 2 with a U-shaped cross-section. The outer wire groove 1 and the inner wire groove 2 have the same opening direction, and the inner wire groove 2 is nested in the outer wire groove 1. An axially extending slide rail 3 is provided on one of the inner surface of the outer wire groove 1 and the outer surface of the inner wire groove 2, and a slide groove 4 corresponding to the position of the slide rail 3 is provided on the other. The slide groove 4 is slidably engaged with the slide rail 3 to realize the adjustment of the length of the telescopic wire groove. A plurality of wire clip assemblies 5 for clamping the wiring harness 10 are arranged at intervals along the extending direction of the wiring harness 10 in the outer wire groove 1 and the inner wire groove 2.

[0033] In this embodiment, both the outer wire groove 1 and the inner wire groove 2 adopt a U-shaped cross-section design, which not only provides enough space to accommodate the wiring harness 10, but also makes the wire groove more stable during installation and use. At the same time, it is also beneficial to heat dissipation and reduces the influence of high temperature caused by long-term work on the wiring harness 10. The inner wire groove 2 is nested in the outer wire groove 1 to form a telescopic structure; an axially extending slide rail 3 is provided on the inner surface of the outer wire groove 1, and a slide groove 4 cooperating with the slide rail 3 is provided on the outer surface of the inner wire groove 2. The sliding cooperation between the slide rail 3 and the slide groove 4 enables the inner wire groove 2 to freely expand and contract in the outer wire groove 1, thereby adjusting the total length of the wire groove. The wire clip assembly 5 is detachably arranged at any position in the outer wire groove 1 and the inner wire groove 2, which provides convenience for fixing the wiring harness 10 to ensure the stability of the wiring harness 10 at different positions.

[0034] It should be noted that the materials of the inner wire groove 2, the outer wire groove 1 and the wire clip assembly 5 can be selected as high-strength plastics, aluminum alloys or composite materials, etc., to meet different environmental and performance requirements and be able to withstand the weight of the wiring harness 10 and the wear during daily use.

[0035] During actual use, pass the wire harness 10 through the telescopic wire groove. According to the length of the wire harness 10 and the requirements of the installation position, adjust the telescopic length of the inner wire groove 2 in the outer wire groove 1, and install the wire clip assembly 5 at the position where the wire harness 10 needs to be fixed to fix the wire harness 10.

[0036] Through the above technical solution, the inner wire groove 2 is nested in the outer wire groove 1, and through the cooperation of the slide rail 3 and the chute 4, the free adjustment of the length of the wire groove is realized; by arranging the wire clip assembly 5 in the inner wire groove 2 and the outer wire groove 1, it provides convenience for the fixation of the wire harness 10, solves the problem that the existing wire grooves cannot meet the requirements of different lengths and layouts of the wire harness 10, with a large variety and quantity, and a large development cost.

[0037] In some embodiments, referring to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 , the wire clip assembly 5 includes a U-shaped base 501 and at least one wire clip 502 arranged on the base 501. A matching clamping structure 6 is arranged between the base 501 and the inner walls of the outer wire groove 1 and the inner wire groove 2, so that the wire clip assembly 5 is clamped at any position on the inner walls of the outer wire groove 1 and the inner wire groove 2. The wire clip assembly 5 is clamped at any position on the inner walls of the outer wire groove 1 and the inner wire groove 2 through the clamping structure 6, and can be accurately adjusted according to the specific layout and needs of the wire harness 10, so as to meet various complex wiring requirements. The setting of the clamping structure 6 ensures the stable connection between the wire clip assembly 5 and the inner wall of the wire groove, prevents the wire clip assembly 5 from loosening or displacing during use, and ensures the stability and safety of the wire harness 10. Moreover, this design enables the telescopic wire groove to adapt to wire harnesses 10 of different numbers and sizes. By increasing or decreasing the number of wire clip assemblies 5, the load-bearing capacity of the wire groove can be flexibly adjusted.

[0038] In some embodiments, referring to Figure 2 、 Figure 4 and Figure 5 , the clamping structure 6 is an installation groove or an installation protrusion arranged on the side surface of the inner surface of the outer wire groove 1 and the inner wire groove 2. A corresponding clamping protrusion or a clamping groove is arranged on the outer side surface of the base 501. The installation groove is clamped and detachably connected with the clamping protrusion, or the installation protrusion is clamped and detachably connected with the clamping groove. In this embodiment, the clamping structure 6 is an installation groove arranged on the side surface of the inner surface of the outer wire groove 1 and the inner wire groove 2, and its shape is adapted to the shape of the U-shaped base 501. The design of the clamping structure 6 is simple, and the staff can easily install or disassemble the wire clip assembly 5 on the wire groove without using special tools or complex operation steps, improving the work efficiency.

[0039] In some embodiments, referring to Figure 1 and Figure 5, the wire clamp 502 has a threading cavity 5021 for accommodating the wire harness 10 and an opening communicating with the threading cavity 5021. The distance between the two ends of the opening is smaller than the outer diameter of the wire harness 10, so as to ensure that when the wire harness 10 penetrates into the threading cavity 5021, it needs to be compressed or deformed to a certain extent, thereby ensuring the stability of the wire harness 10 in the threading cavity 5021. Two guiding plates 5022 extend from the two ends of the opening to the outside of the threading cavity 5021, and the distance between the two guiding plates 5022 gradually increases outward. Both of the two guiding plates 5022 are integrally connected to the wire clamp 502, playing a certain guiding role, enabling the wire harness 10 to penetrate into the threading cavity 5021 more easily and smoothly, and improving the wiring efficiency. When the wire harness 10 is connected to the wire clamp 502, the wire harness 10 is inserted through the opening between the guiding plates 5022, and the wire clamp 502 deforms due to the force, and the guiding plates 5022 expand toward both sides respectively. After the opening between the guiding plates 5022 becomes larger, the wire harness 10 is inserted into the wire clamp 502 and fixedly arranged in the threading cavity 5021.

[0040] In some embodiments, as Figure 6 shown, the wire clamp assembly 5 includes a first wire clamp assembly 503 arranged in the inner wire groove 2 and a second wire clamp assembly 504 arranged in the outer wire groove 1, and at least one of the first wire clamp assembly 503 and the second wire clamp assembly 504 is arranged in the opposite end parts of the inner wire groove 2 and the outer wire groove 1. With such an arrangement, the wire harnesses 10 in the inner wire groove 2 and the outer wire groove 1 can be stably fixed, reducing the risk of loosening or falling off caused by vibration or other external forces, and at the same time improving the management effect of the wire harness 10.

[0041] In some embodiments, referring to Figure 3 , Figure 8 and Figure 10 , it further includes a first fixing buckle 7 fixedly clamped to the installation position. A first clamping groove 101 is arranged on the outer peripheral surface of the outer wire groove 1 along the extending direction of the outer wire groove 1. A first fixing part 701 is arranged on the first fixing buckle 7, and the first fixing part 701 is slidably arranged in the first clamping groove 101 so that the first fixing buckle 7 can move along the extending direction of the outer wire groove 1. The first fixing buckle 7 is used to fix the telescopic wire groove to the installation position (such as a vehicle frame, etc.). Through the first fixing buckle 7, it can be ensured that the wire groove remains stable at the installation position and prevent displacement caused by vibration or other external forces. The first clamping groove 101 provides a sliding track for the first fixing buckle 7, and the first fixing part 701 is slidably arranged in the first clamping groove 101, enabling the first fixing buckle 7 to slide along the extending direction of the first clamping groove 101, thereby adjusting its position on the wire groove to adapt to different wiring requirements.

[0042] In some embodiments, referring to Figure 4 , Figure 9 and Figure 10, further including a second fixing buckle 8 fixedly clamped to the installation position. On the outer peripheral surface of the inner wire groove 2, a second clamping groove 201 is arranged along the extending direction of the inner wire groove 2. A second fixing part 801 is arranged on the second fixing buckle 8, and the second fixing part 801 is slidably arranged in the second clamping groove 201 so that the second fixing buckle 8 can move along the length direction of the inner wire groove 2. The second fixing buckle 8 is used to fix the inner wire groove 2 to the installation position (such as a vehicle frame, etc.). Through the second fixing buckle 8, it can be ensured that the inner wire groove 2 remains stable at the installation position and prevent displacement caused by vibration or other external forces. The second clamping groove 201 provides a sliding track for the second fixing buckle 8. The second fixing part 801 is slidably arranged in the second clamping groove 201, so that the second fixing buckle 8 can slide along the extending direction of the second clamping groove 201, and then adjust its position on the inner wire groove 2 to adapt to different wiring requirements. In this way, through the design of the first fixing buckle 7 and the second fixing buckle 8, the stability of the wire groove at the key position can be ensured, and further improve the overall reliability of the wiring system. At the same time, the cooperation of the first fixing buckle 7 and the second fixing buckle 8 with the wire groove provides a simple and fast installation method, reduces the installation time and complexity, and improves the work efficiency.

[0043] In some embodiments, such as Figure 6 shown, on the outer peripheral surface of the outer wire groove 1, a limiting groove 102 is arranged along the extending direction of the outer wire groove 1. At the position corresponding to the limiting groove 102 on the outer peripheral surface of the inner wire groove 2, a limiting block 202 is arranged, and the limiting block 202 is slidably arranged in the limiting groove 102. With this design, it can ensure the movement directionality and stability of the inner wire groove 2 inside the outer wire groove 1, and at the same time make the inner wire groove 2 not break away from the outer wire groove 1 during the movement process, improving the safety of the overall structure.

[0044] In some embodiments, such as Figure 7 shown, the telescopic wire groove further includes an upper cover 9 covering the opening of the outer wire groove 1. Hooks 901 are arranged on both sides of the upper cover 9. At the position corresponding to the hooks 901 on the outer side surface of the outer wire groove 1, a clamping seat 103 is arranged. The hooks 901 are inserted into the clamping seat 103 and are clamped and connected with the clamping seat 103 to lock the upper cover 9 to the outer wire groove 1. The upper cover 9 can completely cover the opening of the outer wire groove 1 to protect the internal wire harness 10 from external factors such as dust and moisture, thereby improving the safety of the wiring system. The hooks 901 are clamped and connected with the clamping seat 103 to firmly lock the upper cover 9 and the outer wire groove 1 together. Such a connection method is simple and convenient, and the staff can easily open or close the upper cover 9, which is convenient for wiring, adjusting or maintaining the internal wire harness 10.

[0045] In some embodiments, such as Figure 7As shown, a stop block 104 is provided on the outer side surface of the outer wire groove 1. The side of the stop block 104 facing the upper cover 9 abuts against the peripheral edge of the upper cover 9 to limit the continuous movement of the upper cover 9 along the fastening path towards the outer wire groove 1. The stop block 104 provides a definite positioning point for the upper cover 9. When the upper cover 9 moves downward along the fastening path, the stop block 104 will contact the peripheral edge of the upper cover 9, thereby restricting the further movement of the upper cover 9 and ensuring that the upper cover 9 can accurately stay at the predetermined position, avoiding performance problems or safety hazards caused by misalignment or looseness. At the same time, for the staff, the stop block 104 provides an obvious tactile feedback. When the upper cover 9 approaches the predetermined position, the user can confirm whether it has been correctly fastened by feeling the contact between the stop block 104 and the peripheral edge of the upper cover 9. This simplifies the operation process and improves the convenience of use.
