The advantage of the automotive chassis wiring harness is that it can integrate the signals and power of various electronic control systems, thereby reducing the complexity of wiring and improving the reliability and stability of the system.

[0003] The prior art has the following deficiencies: In the "a chassis wiring harness structure" with the publication number of CN219096625U in the prior art, "it includes a wire body, a fixing device is arranged on one side of the wire body, the fixing device includes a first clamping block and a second clamping block, a first threaded hole is opened on one side of the first clamping block, a first circular hole is opened on one side of the second clamping block, a first bolt is threadedly connected to the inner wall of the first threaded hole, a round rod is fixedly connected to one side of the first clamping block, a cylinder is slidably connected to the surface of the round rod, a connecting plate is fixedly connected to one end of the cylinder, a second circular hole is opened on one side of the round rod, a second threaded hole is opened on one side of the cylinder, and a second bolt is threadedly connected to the inner wall of the second threaded hole";

[0004] Through the setting of the fixing device in the above structure, the first clamping block and the second clamping block can be combined to clamp and limit the wire body. Under the action of the round rod and the cylinder, the distance between the wire body and the chassis frame can be adjusted. However, this structure has not been improved in the layout direction of the wiring harness and still adopts the traditional fixed structure. Although this overall fixed structure is conducive to mass production, it cannot provide convenience for operators during the specific installation process, especially for the bent parts of the wiring harness. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a chassis wiring harness structure, which solves the problems of inconvenient wiring harness installation and low installation efficiency existing nowadays.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A chassis wiring harness structure includes a positioning frame, a wiring harness, and a limiting rope. The wiring harness is arranged in the middle inside the positioning frame, and the limiting rope is arranged inside the positioning frame;

[0007] A stretching and bending mechanism is arranged on the periphery of the wiring harness, and a sliding cable is arranged at the inner end of the stretching and bending mechanism;

[0008] The stretching and bending mechanism further includes a rope frame and a grip. The rope frame is fixedly connected to the left and right sides of the stretching and bending mechanism, and the grip is fixedly connected to the rear end of the stretching and bending mechanism.

[0009] As a preferred technical solution of the present invention, the positioning frame includes a limiting frame and a fixed base. The limiting frame is fixedly connected to the side end of the positioning frame, and the fixed base is welded to the bottom of the positioning frame.

[0010] As a preferred technical solution of the present invention, the limiting frame is of an overall columnar structure and is obliquely embedded inside the side end of the positioning frame, and the sliding cable is inserted therein.

[0012] As a preferred technical solution of the present invention, there is a sliding connection relationship between the stretching and bending mechanism and the existing rope, and the stretching and bending mechanism needs to be adjusted to the middle position of the two groups of positioning frames before use.

[0013] As a preferred technical solution of the present invention, the fixed base is movably connected to the vehicle chassis where the wire harness needs to be installed through an external bolt-like structure.

[0014] As a preferred technical solution of the present invention, the bending direction and angle of the limiting rope are consistent with those of the wire harness and the sliding cable.

[0015] Compared with the prior art, the present invention provides a chassis wire harness structure, which has the following beneficial effects:

[0016] For a chassis wiring harness structure, by setting a stretching and bending mechanism, a limiting frame, a rope frame, and a sliding cable, when fixing the automotive wiring harness with this structure, the operator first measures the overall length of the wiring harness to be used, then selects the number of positioning frames to be used according to the length of the wiring harness, and then passes the wiring harness through the middle of the positioning frames. It is necessary to make the wiring harness pass through the stretching and bending mechanism in the middle of every two groups of positioning frames, and pass the limiting rope between the positioning frames, so that the limiting rope is interspersed following the distribution of the positioning frames. The sliding cable needs to pass through the inside of the limiting frame and the stretching and bending mechanism. At this time, it can be arranged one by one according to the required direction of the wiring harness. At the bent position, the operator can pull the grips in the middle of the two groups of positioning frames to make the stretching and bending mechanism pull the wiring harness and the sliding cable until the required angle is formed between the two end positioning frames, and then dial the limiting rope to the same bending direction as the wiring harness; through the above process and settings, this structure can not only quickly bend and fix the wiring harness, but also can be flexibly adjusted according to the length of the wiring harness to be used. The number of different positioning frames and the spacing between the positioning frames can be adjusted, and thus reserve space for the wiring harness to improve the installation efficiency of the wiring harness.

[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4, in this implementation: A chassis wiring harness structure includes a positioning frame 1, a wiring harness 2, and a limiting rope 3. The wiring harness 2 is disposed in the middle inside the positioning frame 1. The wiring harness 2 is used to control the vehicle. The limiting rope 3 is disposed at the inner end of the positioning frame 1. The limiting rope 3 limits the position of the wiring harness 2 from the side of the wiring harness 2.

[0024] A stretching and bending mechanism 4 is disposed around the wiring harness 2. The stretching and bending mechanism 4 can quickly adjust the wiring harness 2 to a suitable bending angle. A sliding cable 5 is disposed at the inner end of the stretching and bending mechanism 4. The sliding cable 5 fixes the position of the stretching and bending mechanism 4 and provides a sliding adjustment path.

[0025] The stretching and bending mechanism 4 further includes a rope frame 401 and a grip 402. The rope frame 401 is fixedly connected to the left and right sides of the stretching and bending mechanism 4. The grip 402 is fixedly connected to the rear end of the stretching and bending mechanism 4.

[0026] In this embodiment, the positioning frame 1 includes a limiting frame 101 and a fixed base 102. The limiting frame 101 is fixedly connected to the side end of the positioning frame 1. The fixed base 102 is welded to the bottom of the positioning frame 1. The limiting frame 101 is of an overall columnar structure and is obliquely embedded in the inner part of the side end of the positioning frame 1. The sliding cable 5 is inserted therein.

[0027] Specifically, the limiting frame 101 obliquely embedded in the positioning frame 1 can accommodate the sliding cable 5 that bends and passes through it.

[0028] In this embodiment, the limiting rope 3 is inserted between the positioning frames 1, and the end of the limiting rope 3 is not fixed before the overall installation of the wiring harness 2 is completed. There is a sliding connection relationship between the stretching and bending mechanism 4 and the sliding cable 5. The stretching and bending mechanism 4 needs to be adjusted to the middle position between the two groups of positioning frames 1 before use.

[0029] Specifically, when the stretching and bending mechanism 4 is not in the middle of the two groups of positioning frames 1, the stretching and bending mechanism 4 can be dragged left and right so that it is in the middle of the two groups of positioning frames 1. When it is in the middle of the two groups of positioning frames 1, the sliding cable 5 can be dragged more evenly.

[0030] In this embodiment, the fixed base 102 is movably connected to the vehicle chassis where the wiring harness 2 needs to be installed through an external bolt-like structure. The bending direction and angle of the limiting rope 3 are consistent with those of the wiring harness 2 and the sliding cable 5.

[0031] Working principle and usage process of the utility model: When fixing the automotive wiring harness 2 with this structure, the operator first measures the overall length of the wiring harness 2 to be used, then selects the number of positioning frames 1 according to the length of the wiring harness 2, and then passes the wiring harness 2 through the middle of the positioning frame 1. It is necessary to make the wiring harness 2 pass through the stretching and bending mechanism 4 in the middle of every two groups of positioning frames 1, and pass the limiting rope 3 between the positioning frames 1, so that the limiting rope 3 is inserted following the distribution of the positioning frames 1. The sliding cable 5 needs to pass through the limiting frame 101 and the inside of the stretching and bending mechanism 4. At this time, it can be arranged one by one according to the required direction of the wiring harness 2. At the bent position, the operator can pull the grips 402 in the middle of the two groups of positioning frames 1 to make the stretching and bending mechanism 4 pull the wiring harness 2 and the sliding cable 5 until the required included angle is formed between the two end positioning frames 1, and then move the limiting rope 3 to the same bending direction as the wiring harness 2.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
