[0002] Traditional automotive wiring harnesses are mostly fixed in length. In actual use, there may be problems such as the wiring harness being messy and tangled. This may cause the wiring harness to be tight and the possibility of loose connections at the joints, thus affecting the use of related equipment.

[0003] The utility model patent with reference application number CN202021533537.1 discloses a stretchable automotive wiring harness that can be stretched to a length according to actual needs to meet the needs of actual use. However, the above patent can only achieve the function of stretching the wiring harness, and cannot be adjusted and fixed according to the required length. As a result, even if it can be stretched to a certain length during use, a pulling effect will still be generated at both ends of the wiring harness under the action of elastic force, and long-term use will still affect the safety of the joints.

[0004] Therefore, those skilled in the art provide an automotive wiring harness that is convenient for wire reeling, so as to solve the problems raised in the above background technology. Utility Model Content

[0032] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0033] Example 1

[0034] See also Figure 1 and Figure 2 In this embodiment, an automotive wiring harness that is easy to take up is provided, including a take-up drum 1, a rotatable take-up shaft 2 is provided in the take-up drum 1, and the automotive wiring harness is wound on the take-up shaft 2, wherein the take-up drum 1 has symmetrical adjustment grooves 11 on the sides, and the adjustment grooves 11 on both sides are respectively used for moving and adjusting the head and tail of the automotive wiring harness.

[0035] The rotatable take-up shaft 2 is used to achieve the purpose of taking up and releasing the vehicle wire harness during forward and reverse rotation, thereby achieving the purpose of storing and retracting the wire harness and adjusting its length.

[0036] In order to solve the problem of fixing the stretched length of the wire harness after extension and retraction, this solution provides a retractable clamping device 43.

[0037] Combine Figure 1 and Figure 3 As shown, the telescopic clamping device 43 includes a clamping ring 31 and a clamping ring 31 sleeve. The clamping ring 31 is wrapped around the outer periphery of the vehicle wiring harness, and the clamping ring 31 sleeve is connected to the outer periphery of the clamping ring 31. The bottom of the clamping ring 31 sleeve is annular and the top is open. A lug 33 extends upward from the opening of the clamping ring 31 sleeve, and a hole groove 34 is provided on the lug 33 for locking the clamping ring 31 sleeve.

[0038] In addition, the telescopic clamping device 43 also includes a fixing part 35, and two groups of hole grooves 34 are longitudinally arranged on the lug 33. The two groups of hole grooves 34 are respectively an upper groove 341 and a lower groove 342. The lower groove 342 is arranged at the near center end of the clamp ring 31, and the upper groove 341 is arranged at the far center end of the clamp ring 31. The hole grooves 34 are provided with holes whose center lines are aligned with each other. The fixing part 35 is detachable and arranged in the upper groove 341 and the lower groove 342. A gasket 36 is also provided on the other side of the fixing part 35.

[0039] In a preferred embodiment, the collar 31 is made of rubber, which has friction properties and creates friction with the outer periphery of the vehicle wiring harness, thereby facilitating the fixing of the wiring harness's operating length. The collar 31 is made of a deformable composite plastic, such as PE, PP, or a composite plastic. Deformability refers to the ability of the collar 31 to radially deform and compress under external pressure, providing a certain degree of flexibility, rather than being a completely rigid, inflexible structure.

[0040] When using this structure, after adjusting to the appropriate length, the deformable collar 31 is used to clamp the tail end of the wiring harness. When the telescopic length is not fixed, the fixing member 35 can be placed in the upper groove 341 to prevent it from being lost. Due to the friction between the collar 31 on the inner wall and the vehicle wiring harness, it is not easy to fall. When the telescopic length needs to be fixed, the fixing member 35 needs to be installed in the lower groove 342, that is, set at the proximal end. At this time, under the action of the fixing member 35, the deformation ability of the collar 31 is limited, achieving the effect of fixing and preventing it from sliding. The collar 31 is larger than the size of the adjustment slot 11, forming a limit outside the adjustment slot 11, thereby fixing the telescopic length.

[0041] In order to further solve the problem of fixing the stretched length of the wiring harness after extension and retraction, the present solution also provides a rotating shaft fixing device.

[0042] Combine Figure 4 and Figure 5 As shown, the rotating shaft fixing device includes a fixing ring 41 and a limiting ring 42. One end of the take-up shaft 2 is passed through the outside of the take-up drum 1. The limiting ring 42 is installed on the outside of the take-up shaft 2 relative to the take-up drum 1. A limiting groove 43 is provided on the limiting ring 42. The fixing ring 41 is arranged in a circular ring shape. A limiting member 44 is provided on the inner periphery of the fixing ring 41, and a clamping block 45 is provided on the axial extension of the fixing ring 41. A clamping groove 12 is provided on the axial direction of the take-up drum 1 relative to the outer periphery of the take-up shaft 2. The limiting member 44 matches the limiting groove 43, and the clamping block 45 matches the clamping groove 12.

[0043] When using this structure, since the forward and reverse rotation of the take-up shaft determines the extension of the wire harness, fixing the take-up shaft so that it does not rotate can also produce a fixing effect on the telescopic length of the wire harness. When fixing is required, the fixing ring 41 is buckled on the outside of the limiting ring 42. The fixing ring 41 limits the rotation of the rotating shaft to prevent the rotation of the rotating shaft from causing the extension and contraction of the wire harness, which is convenient for fixing the telescopic length of the wire harness and will not pull the wire harness.

[0044] As a further example:

[0045] A magnet 6 adsorbing part 5 is provided in the card slot 12, and a magnet 6 is provided at the card block 45 to be attracted to the magnet 6 adsorbing part 5, so that the magnetic fixing effect is better when engaged.

[0046] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
