Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0032] like Figures 1-8As shown, a preferred embodiment of the present invention provides a threading cover, comprising a base 1, a middle sleeve 2, and a top cover 3. The base 1 includes a base body 11 and a base plate 12. The base body 11 is cylindrical and made of a tough material. The base body 11 has a first opening 111 along its axial direction, extending through the base body 11. The base plate 12 is fixed to and extends along a first side edge 112 of the base body 11. The first side edge 112 is the bottom edge of the cylindrical base body. The base plate 12 has multiple notches 121 spaced apart along the extending direction of the first side edge 112. The notches 121 contribute to the structural strength of the base 1. The design is weakened so that the base support body 11 can unfold into a plane. The middle sleeve 2 is detachably assembled inside the base support body 11. The top of the middle sleeve 2 is provided with a locking flange 21, which forms a groove with the outer wall of the middle sleeve 2. The top edge of the base support body 11 is embedded in the groove, and the groove limits and fixes the base support body 11, making it easy for the flexible base support 1 to be bent into a set arc shape. The top cover 3 includes a top cover body and a top plate. The top cover body is detachably assembled inside the middle sleeve 2. The top cover body is provided with a threading space. The top plate is fixed to the top cover body and is provided with an elastic pad. The elastic pad has a threading opening, which communicates with the threading space. After the threading cover is assembled, the middle sleeve 2 is a cylindrical structure, the top cover body is a cylindrical structure, and the base support body 11 is a cylindrical structure. The middle sleeve 2, the top cover body, the base support body 11, the top plate, and the bottom plate 12 are all coaxially arranged.

[0033] In this embodiment, the cable guide cover has a first opening 111 on the base body 11 and a notch 121 on the base plate 12, allowing the base body 11 to unfold into a flat surface. This avoids the base plate 12 interfering with the unfolding of the base body 11 and facilitates the entire base 1 passing through a smaller opening. This makes the cable guide cover of this embodiment convenient to use in small spaces. When the cable harness 4 and connector 41 are led out of the vehicle seat cover 5, there is no need to make a large cut. The top cover 3 and the middle cover 2 are detachably connected, and the middle cover 2 and the base 1 are detachably connected, which is convenient for disassembly and assembly. An elastic pad is provided on the top plate of the top cover 3. The elastic pad is a soft rubber pad with a cable guide opening. The cable harness 4 is led out through the cable guide opening. The elastic pad is elastic and will not cause wear to the cable harness 4 at the cable guide opening. This ensures that the cable harness 4 can pass through and be led out, and can also effectively cover the cut made on the cover 5 when the cable harness 4 and connector 41 are led out, avoiding tearing or wear of the cut after long-term use and improving the appearance.

[0034] In this embodiment, as Figure 2As shown, the base body 11 is provided with a positioning guide boss 113, and the middle sleeve 2 has a second opening 22 along the axial direction. The positioning guide boss 113 is guided and assembled within the second opening 22. The positioning guide boss 113 is located on the inner wall of the base body 11 and extends in a direction parallel to the axial direction of the base body 11. The cooperation between the positioning guide boss 113 and the second opening 22 provides a positioning and guiding function for the assembly of the middle sleeve 2 within the base body 11, making the assembly faster and more precise. Furthermore, the positioning guide boss 113 and the first opening 111 are positioned opposite each other. After the middle sleeve 2 is inserted into the base body 11, the first opening 111 is closed by the middle sleeve 2, and the second opening 22 is closed by the base body 11, so that the assembly of the middle sleeve 2 and the base body 11 is a closed sleeve, preventing the wire harness 4 from slipping out. Furthermore, by adopting the form of setting a first opening 111 and a second opening 22, the technical effect of assembling from the middle section of the wire harness 4 can be achieved. The middle section of the wire harness 4 is inserted into the base body 11 through the first opening 111 and into the middle sleeve 2 through the second opening 22. Then, the middle sleeve 2 and the base body 11 are assembled, so that the wire harness 4 is located inside the closed assembly of the middle sleeve 2 and the base body 11. It can be directly assembled from the middle section of the wire harness 4 without having to pass through the middle sleeve 2 or the base body 11 from the connector 41 of the wire harness 4. This can reduce the size of the middle sleeve 2 and the base body 11 and improve the assembly efficiency.

[0035] In this embodiment, the notch 121 is a V-shaped notch. The bottom of the V-shaped notch is located on the first side edge 112, and the opening of the V-shaped notch faces away from the first side edge 112. This allows the various parts of the base plate 12 to be joined together to form a complete plate when the base body 11 is unfolded into a plane. The length of the base plate 12 is consistent with the unfolded length of the base body 11. When the base body 11 is wound into a cylinder, the base plate 12 serves as the bottom flange plate of the base body 11. The spaced V-shaped notches divide the base plate 12 into multiple components, which can abut against the cut of the faceplate 5 to prevent the base body 11 from coming out of the cut.

[0036] Furthermore, such as Figure 2 As shown, the base body 11 is provided with a plurality of strip-shaped grooves 115 spaced circumferentially. The length direction of the strip-shaped grooves 115 is arranged parallel to the axial direction of the base body 11, and each strip-shaped groove 115 corresponds to and communicates with each of the V-shaped notches. The strip-shaped grooves 115 weaken the structural strength of the base body 11, making the base body 11 easier to unfold or bend.

[0037] In this embodiment, as Figures 2-4As shown, the base body 11 has multiple first connecting parts, and the middle sleeve 2 has multiple second connecting parts. The first connecting parts and the second connecting parts are arranged in a one-to-one correspondence. Each first connecting part is one of a wedge block 23 and a mounting hole 114 that fits the wedge block 23. The second connecting part corresponding to the first connecting part is the other of the wedge block 23 and the mounting hole 114. When the middle sleeve 2 is assembled inside the base body 11, the wedge block 23 is embedded in the mounting hole 114 to connect the middle sleeve 2 to the base body 11. When the first connecting part is a wedge block 23, the second connecting part is the mounting hole 114; when the first connecting part is the mounting hole 114, the second connecting part is the wedge block 23. The types of the first connecting parts on the base body 11 can be different; that is, all the first connecting parts on the base body 11 can be wedge blocks 23, all can be mounting holes 114, or some can be wedge blocks 23 and some can be mounting holes 114. Correspondingly, the type of the second connecting part on the middle sleeve 2 corresponds to the type of the first connecting part on the base body 11. In this embodiment, the first connecting parts on the base body 11 are all mounting holes 114, and the second connecting parts on the middle sleeve 2 are all wedge-shaped blocks 23. The wedge-shaped blocks 23 are larger at the top and smaller at the bottom, which facilitates insertion into the mounting holes 114 from top to bottom. After the wedge-shaped blocks 23 are inserted into the mounting holes 114, they act as a stop for the base body 11, preventing the base body 11 from slipping off.

[0038] In this embodiment, the locking flange 21 extends circumferentially along the middle sleeve 2, limiting the top edge of the base body 11 and shaping the base body 11 into a cylinder. Optionally, in other embodiments, multiple locking flanges 21 are provided, and the multiple locking flanges 21 are spaced apart circumferentially along the middle sleeve 2.

[0039] In this embodiment, a top cover side plate is provided along the outer edge of the top plate extending axially. The top cover side plate and the top cover body are located on the same side of the top plate. The top plate and the top cover side plate cover the face sleeve 5 led out from the wire harness 4, forming a closed space, improving the sealing performance, and beautifying the appearance of the face sleeve cut.

[0040] In this embodiment, the elastic pad covers the port of the wiring space of the top cover body to improve shielding. The top cover body is in the form of a sleeve, and the internal space of the sleeve is the wiring space. The elastic pad covers one end of the sleeve, and the wiring port on the elastic pad is coaxially arranged with the top cover body.

[0041] In this embodiment, as Figure 5 and Figure 6As shown, the top cover body includes a first top cover body 31 and a second top cover body 33, and the top plate includes a first top plate 32 and a second top plate 34. The first top plate 32 is fixed to the first top cover body 31, and the second top plate 34 is fixed to the second top cover body 33. The first top plate 32 is provided with a first elastic pad 35, and the second top plate 34 is provided with a second elastic pad 36. Both the first elastic pad 35 and the second elastic pad 36 are provided with a wire harness avoidance notch 37. The first top cover body 31 and the second top cover body 33 are connected by a mating joint. The wire harness avoidance notch 37 of the first elastic pad 35 and the wire harness avoidance notch 37 of the second elastic pad 36 are mated to form the wire passage. This structural form facilitates assembly from the middle section of the wire harness 4, eliminating the need for the connector 41 of the wire harness 4 to pass through the wire passage of the top cover body, reducing the size of the wire passage, improving shielding, and increasing assembly efficiency. In this embodiment, both the first top cover body 31 and the second top cover body 33 are semi-circular tubes, joined together to form a sleeve-shaped top cover body; both the first top plate 32 and the second top plate 34 are semi-circular plates, joined together to form a circular top plate; both the first elastic pad 35 and the second elastic pad 36 are semi-circular, joined together to form a circular top plate, and the wiring harness notch 37 is semi-circular, joined together to form a circular wire passage. The first top plate 32 is provided with a first top cover side plate 321, and the second top plate 34 is provided with a second top cover side plate 341. Both the first top cover side plate 321 and the second top cover side plate 341 are semi-circular tubes. When the first top cover body 31 and the second top cover body 33 are joined together, the first top cover side plate 321 and the second top cover side plate 341 are joined together to form a complete cylindrical top cover side plate.

[0042] Furthermore, the first top cover body 31 is provided with one of a mating protrusion 311 and a mating groove 331, and the second top cover body 33 is provided with the other of a mating protrusion 311 and a mating groove 331. The mating protrusion 311 is inserted into the mating groove 331, realizing a detachable connection between the first top cover body 31 and the second top cover body 33, thereby realizing the assembly of the top cover 3. The mating surfaces of the first top cover body 31 and the second top cover body 33 are parallel to the axial direction, and both the mating protrusion 311 and the mating groove 331 are provided on the mating surfaces. Multiple mating protrusions 311 and mating grooves 331 can be set vertically at intervals to improve connection stability.

[0043] In this embodiment, the top cover body and the middle sleeve 2 are connected by threads, and the outer wall of the top cover body and the inner wall of the middle sleeve 2 are both provided with threads. When the top cover body includes a first top cover body 31 and a second top cover body 33, both the first top cover body 31 and the second top cover body 33 are provided with threads, and the first top cover body 31 and the second top cover body 33 form a complete thread after docking.

[0044] In this embodiment, the wiring cover can be installed on the back cover 5 of the vehicle seat before the vehicle leaves the factory, or it can be installed on the cover after the vehicle is customized, by cutting a slit in the cover and installing the wiring cover at the slit to bring out the reserved wiring harness 4 and connector 41 inside the seat.

[0045] When inserting the base 1 into the cut, the base body 11 can be unfolded into a flat surface to reduce its size. After inserting the base 1 into the cut, the base body 11 can be bent into a cylinder with the help of a tool, and the base plate 12 can be placed against the face sleeve 5. Then, the middle section of the wire harness 4 is inserted into the base body 11 and the middle sleeve 2 through the first opening 111 and the second opening 22. The middle sleeve 2 is assembled into the base body 11. Then, the first top cover body 31 and the second top cover body 33 are connected from both sides, and the middle section of the wire harness 4 is placed in the wire insertion port, so that the wire harness 4 is led out from the wire insertion port.

[0046] If the wiring cover has been installed before the vehicle leaves the factory, then during subsequent use, the top cover 3 and the middle sleeve 2 can be removed first, the wiring harness 4 can be embedded into the bottom bracket body 11 and the middle sleeve 2, and then the above installation method can be repeated to install the middle sleeve 2 and the top cover 3, and the wiring harness 4 can be led out from the wiring port.

[0047] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
