Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harnesses, specifically to an L-shaped stepped body wiring harness bracket. Background Technology

[0002] The rapid development of automotive electrification and intelligentization has led to a dramatic increase in the length, weight, and complexity of in-vehicle wiring harnesses. These "nerves" carrying electricity and signals must traverse the harsh environment of the vehicle body, enduring continuous vibration and impact, extreme temperature changes, oil and moisture, and potential physical wear. Early simple binding or fixing methods using gaps in the vehicle body had significant drawbacks: unreliable fixing easily led to harness loosening, rattling noises, and even short circuits due to wear; lack of effective protection made the harness susceptible to environmental corrosion and mechanical damage; and messy wiring affected assembly efficiency and safety. Therefore, vehicle body wiring harness brackets emerged as an engineered solution. Their core function is to provide precise and secure fixing of the wiring harness, act as a key physical protective barrier, and optimize the wiring path. In terms of materials, there has been a complete shift from metals that are easily corroded and damaged by the harness to engineering plastics (such as reinforced PA66 and PP)—which offer advantages such as lightweight, corrosion resistance, good insulation, flexible design, and injection molding mass production. Modern vehicle body wiring harness brackets have become an indispensable key component for ensuring the safe and reliable operation of the vehicle's massive electrical system. Utility Model Content

[0003] This invention addresses the problems of existing vehicle wiring harness brackets, such as difficulty in accurately fitting complex corners and edges of the vehicle body, low space utilization, and insufficient fixing stability. It provides an L-shaped stepped vehicle wiring harness bracket, aiming to improve the fixing and protection effect of the wiring harness and reduce the failure rate.

[0004] The technical solution of this utility model is: an L-shaped stepped vehicle body wiring harness bracket, comprising a bracket body, characterized in that the bracket body is an L-shaped bracket body formed by splicing a long side wiring harness groove and a short side wiring harness groove, the long side wiring harness groove includes a long base plate and baffles located on both sides of the long base plate, the short side wiring harness groove includes a short base plate and baffles located on both sides of the short base plate, the short base plate has a three-section bending structure, and the bending angle of the short base plate from top to bottom is 110°±5° and 100°±2° respectively;

[0005] The long side wire harness groove is provided with a fastening pin hole at each end. The short side wire harness groove is located between the two fastening pin holes. The baffle of the long side wire harness groove is provided with a first extension plate and a second extension plate. The first extension plate and the second extension plate are respectively provided with positioning holes.

[0006] This invention features an L-shaped main structure that perfectly fits the corner space layout of the vehicle frame. The stepped curvature of the short-side wiring harness groove allows it to closely conform to the irregular curves and height variations of the vehicle frame edge. The long-side wiring harness groove is secured using a combination of clip holes and positioning holes, optimizing the overall fixation effect.

[0007] Further preferably, the positioning hole is an elliptical positioning hole, and the major axis of the positioning hole is 12mm and the minor axis is 6mm.

[0008] This invention facilitates subsequent positioning and installation through the elliptical positioning hole.

[0009] Further preferably, the height of the first extension plate is less than the height of the second extension plate, and the hole spacing between two adjacent mounting holes is 95mm.

[0010] The mounting holes of different heights and spacings can be used to adapt to different interior space layouts.

[0011] In a further preferred embodiment, the long side wire harness groove and the short side wire harness groove are each provided with at least two sets of cable tie fixing holes along the axial direction at a preset interval.

[0012] Cable tie perforations are used to thread cable ties through the cable ties, ensuring that the wiring harness fits snugly against the bracket slot and preventing the harness from bulging out and interfering with other layouts inside the vehicle.

[0013] Preferably, the fastening pin hole adopts a threaded hole pre-positioning structure to prevent displacement of the bracket.

[0014] Beneficial effects:

[0015] Stepped routing design: The stepped curvature of the short side wiring harness groove can closely fit the irregular curved surfaces and height changes of the vehicle body frame edge.

[0016] The fixing method involves combining the long side with elliptical openings (to accommodate bolt installation position tolerances) and tight-fitting clips; the short side is secured using cable ties with through-holes for multi-point, flexible binding. The staircase itself also provides physical support.

[0017] Compared to traditional brackets, the significant advantages of this invention are:

[0018] Excellent spatial fit: The L-shaped structure and stepped layout make full use of the corners and edges of the vehicle body to achieve a precise and close fit with the body.

[0019] More secure and reliable fixation: The combination of buckles, bolt holes (oval shape for strong adaptability) and multi-point cable ties effectively suppresses wire harness vibration and displacement, preventing loosening and slapping.

[0020] Excellent support and protection: The stepped structure provides continuous and stable support for the main wire harness, reduces bending stress, and effectively isolates the sharp edges of the vehicle body and potential sources of wear.

[0021] Highly adaptable to different installation points: Multiple fixing interfaces (clip, bolt hole, cable tie hole) to meet the requirements of different installation points.

[0022] Improved system reliability: Superior fixing and protection. Through a dual fixing method of pre-fixing with clips and secondary fastening with cable ties, as well as a design that fits the vehicle body structure, the incidence of wiring harness wear, short circuits and other failures is effectively reduced, maintenance costs are reduced, and the stability and reliability of the vehicle's electrical system are significantly improved.

A fastening pin hole 1 is provided at the end of the long side wiring harness groove. The short side wiring harness groove is located between two fastening pin holes. A first extension plate 2 and a second extension plate 5 are provided on the baffle of the long side wiring harness groove. Positioning holes 3 are respectively opened on the first extension plate and the second extension plate.

[0029] This invention features an L-shaped main structure that perfectly fits the corner space layout of the vehicle frame.

[0032] Further optimization involves providing at least two sets of cable tie fixing holes 6 along the axial direction at preset intervals for both the long-side and short-side wire harness slots. These cable tie holes are used to thread cable ties through the slots, ensuring the wire harness fits snugly against the bracket slots and preventing it from protruding and interfering with other interior layouts.

[0033] Further optimization involves using a threaded pre-positioning structure for the fastening pin holes to prevent displacement of the bracket.

[0034] Beneficial effects:

[0037] Compared to traditional brackets, the significant advantages of this invention are:

[0038] Excellent spatial fit: The L-shaped structure and stepped layout make full use of the corners and edges of the vehicle body to achieve a precise and close fit with the body.

[0039] More secure and reliable fixation: The combination of buckles, bolt holes (oval shape for strong adaptability) and multi-point cable ties effectively suppresses wire harness vibration and displacement, preventing loosening and slapping.
