Description

[0002] Automotive wiring harness positioning devices, also commonly known as wiring harness rubber sleeves or protective sleeves, are an indispensable component of automotive wiring harness systems. Their main function is to protect the wiring harness from damage by the external environment, while ensuring that the wiring harness can accurately and stably pass through the body holes during installation.

[0003] During the use of the existing automotive wiring harness positioning device, the outer sleeve is soft and cannot play a good guiding role. Several wiring harnesses are prone to twisting, and the guiding effect is poor, which is not conducive to the later individual inspection of a certain wiring harness. In addition, guide holes are usually configured to guide the distribution of the sleeve, which is troublesome and inconvenient, and it is easy to loosen after installation. When the wire harness in the lead is too long or the wire harness is bent, the sleeve itself is soft and bends accordingly, and cannot play a guiding role. The problem of wrinkling and bending at multiple locations on the surface of the wire harness will occur, which is not conducive to neat wiring.

DETAILED DESCRIPTION

[0031] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0032] like Figure 1-Figure 10 The shown automobile wiring harness positioning device comprises a sleeve 1, a plurality of rotating columns 3 are rotatably inserted on the upper surface of the sleeve 1, the upper end of the rotating column 3 is fixedly connected to a limiting folding plate 2, the lower end of the rotating column 3 extends to the inner side of the sleeve 1 and is fixedly connected to a connecting plate 6, a connecting column 7 is fixedly connected to the upper surface of the connecting plate 6 and at one end away from the rotating column 3, the upper end of the connecting column 7 slides through the sleeve 1 and is fixedly connected to an elastic plate 8, a steering adjustment mechanism is arranged between the rotating column 3 and the sleeve 1, a shaping rib 11 is fixedly connected to the inner bottom surface of the sleeve 1, a plurality of lifting columns 13 are slidably inserted on the lower surface of the shaping rib 11, a mounting mechanism is arranged at the lower end of the lifting column 13, and V-shaped tightening members are fixedly connected to the two side surfaces of the lifting column 13 near the upper end.

[0033] like Figure 2 , Figure 3 , Figure 4 As shown, the steering adjustment mechanism includes a chassis 4 arranged on the surface of the connecting plate 6, and the chassis 4 is fixedly connected to the lower end of the rotating column 3, the outer surface of the rotating column 3 is sleeved with a compression spring 5, and the compression spring 5 is located on the inner side of the sleeve 1, and the limiting columns 10 are fixedly connected to the lower surface of the limiting folding plate 2 on both sides, and the upper surface of the sleeve 1 is respectively provided with a plurality of limiting holes 29 corresponding to the outer periphery of each rotating column 3, and each limiting column 10 is correspondingly slidably inserted into the inner side of one of the limiting holes 29. This part is designed to facilitate the limiting folding plate 2 to quickly rotate and change the angle.

[0034] An arc-shaped opening 9 is provided on the upper surface of the sleeve 1 at a position corresponding to the connecting column 7. The central axis of the arc corresponding to the arc-shaped opening 9 is coaxial with the central axis of the rotating column 3. The connecting column 7 slides through the inner side of the arc-shaped opening 9. When the limiting folding plate 2 rotates, the connecting column 7 slides along the inner side of the arc-shaped opening 9.

[0035] like Figure 1 , Figure 6 As shown, a plurality of branch ribs 12 extend from both side edges of the shaping rib 11, and the lower surface of the branch rib 12 is fixedly connected to the inner bottom surface of the sleeve 1. The branch rib 12 is used to increase the connection strength with the inner bottom surface of the sleeve 1. The shaping rib 11 and the branch rib 12 are made of aluminum alloy and can be bent and deformed.

[0036] like Figure 7 , Figure 8As shown, the V-shaped tightening member includes an inclined rod 16, the lower end of the inclined rod 16 is vertically slidably matched with the side surface of the shaping rib 11, and the lower end of the inclined rod 16 is fixedly connected to the outer surface of the lifting column 13, and the upper end of the inclined rod 16 is connected to the tightening rod 18 through the bending portion 17. The inclined rod 16, the bending portion 17 and the tightening rod 18 can be integrally formed and made of plastic material, and the bending portion 17 can be bent when slightly pushed.

[0037] A columnar hole 14 is formed on the lower surface of the shaping rib 11, and sliding openings 15 are formed on both sides of the columnar hole 14. The upper end of the lifting column 13 is slidably inserted into the inner side of the columnar hole 14, and the lower end of the tilting rod 16 is slidably inserted into the inner side of the sliding opening 15. As the lifting column 13 moves upward, the tilting rod 16 can slide upward along the inner side of the sliding opening 15.

[0038] like Figure 5 As shown, the upper end of the connecting column 7 is fixedly connected with a tough plate 27, and the upper end of the tough plate 27 is provided with a widened edge 28, and the tough plate 27 and the widened edge 28 are fixedly embedded in the elastic plate 8. The tough plate 27 is made of plastic material, and the elastic plate 8 is made of plastic material. The widened edge 28 is used to ensure the stability of the embedded installation and prevent the tough plate 27 from separating from the elastic plate 8.

[0039] like Fig. 9 , Fig.10 As shown, the mounting mechanism includes a threaded sleeve 21 threadedly sleeved at the lower end of the outer surface of the lifting column 13, a mounting seat 23 is fixedly connected to the lower end of the outer surface of the threaded sleeve 21, an adhesive patch 24 is fixedly connected to the lower surface of the mounting seat 23, a protective patch 25 is fixedly connected to the lower surface of the adhesive patch 24, a tearing portion 26 extends from the edge of the protective patch 25, and a sharpened head 20 is provided at the lower end of the lifting column 13. The adhesive patch 24 is made of a polyester film material with adhesive on the surface to achieve a better adhesion effect.

[0040] A polygonal sleeve 22 is provided at the upper end of the outer surface of the threaded sleeve 21, and a limit sleeve 19 is fixedly provided on the outer surface of the lifting column 13 near the upper part of the threaded sleeve 21. The polygonal sleeve 22 facilitates the user to rotate the threaded sleeve 21, and the limit sleeve 19 plays a limiting role to prevent the threaded sleeve 21 from excessively moving upward when rotating.

[0041] During use, the user winds the wire around the outer surface of the sleeve 1. During the winding process, the user bends the elastic plate 8 so that the tough plate 27 bends toward the side away from the limiting folding plate 2. Then the wire can be placed between the limiting folding plate 2 and the elastic plate 8, which plays a guiding and limiting role, making it convenient to form a coiled wire 30 on the surface of the sleeve 1, and the arrangement is convenient and quick.

[0042] The user lifts up the limit folding plate 2 and squeezes the compression spring 5, so that the limit column 10 is separated from the inner side of the limit hole 29. Then, the user can rotate the limit folding plate 2. After releasing the limit folding plate 2, the user can rotate it slightly. Under the elastic force of the compression spring 5, the limit column 10 will be inserted into the limit hole 29 at other positions to achieve the positioning purpose. Using this method, the winding angle of the winding wire 30 can be flexibly adjusted, and the lead wire can be flexibly coiled to adapt to the bending of the sleeve 1.

[0043] After the user applies appropriate external force to the sleeve 1, the shaping rib 11 is deformed, so that the sleeve 1 can maintain its shape after bending, so that the coiled wire 30 on the surface of the sleeve 1 and the through wiring passing through the inside of the sleeve 1 can be guided and reversed, and the wiring is flexible and convenient when guiding.

[0044] The user can peel off the protective sticker 25 through the tearing portion 26 to expose the adhesive sticker 24. After the sleeve 1 is bent to the target degree, it can be installed at the target position through the adhesive sticker 24. The installation at several points below the sleeve 1 ensures the stability of the installation and is also beneficial to the bending plasticity of the sleeve 1.

[0045] Before the adhesive patch 24 is adhered, the user can rotate the threaded sleeve 21 so that the pointed head 20 extends out of the inner side of the threaded sleeve 21, so as to penetrate the surface of a material such as a sound insulation pad when installing, thereby reinforcing the installation and preventing the problem of unstable installation caused by the adhesive effect alone when installing on a sound insulation pad or the like.

[0046] When the sleeve 1 is fixed to the installation surface, due to the effect of gravity, the lifting column 13 moves upward along the inner side of the columnar hole 14, and the tilting rods 16 on both sides also move upward synchronously. When the upper end of the tightening rod 18 is pushed by the inner wall of the sleeve 1, the upper ends of the tightening rods 18 on both sides rotate in directions close to each other, thereby clamping the passing wiring. Therefore, it can play a role in tightening the internal wiring during installation to prevent loosening.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
