Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile wire harness fixing, in particular to wire harness support. BACKGROUND

[0002] In modern electrical engineering, wire harnesses are an important component of power transmission and signal transmission, and their rational layout and effective management are crucial for ensuring the normal operation of equipment. However, existing wire harness management and fixing methods have several shortcomings that affect the efficiency, safety, and aesthetics of overall wiring.

[0003] Firstly, traditional wire harness management methods usually rely on simple binding or the use of basic clamps for fixing, which often results in a jumbled accumulation of wires, occupying a large amount of space and increasing the risk of mutual interference between wires, reducing system reliability and maintenance convenience. In addition, when wires need to be inspected or repaired, complex wiring structures make operations difficult and time-consuming.

[0004] Secondly, some existing wire harness support designs lack flexibility and are difficult to adapt to wires of different sizes and shapes as well as complex and variable application scenarios. For example, some supports may only provide limited fixing points, failing to meet diverse wiring needs; or additional tools are required for adjustment during installation, increasing the difficulty and time cost of work.

[0005] Furthermore, many existing wire harness management systems fail to adequately consider wire entry and exit issues. Without specially designed wire ramps or other auxiliary facilities, wires are prone to wear and tear when they are connected or disconnected from the wire harness, shortening their service life and potentially causing safety hazards.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] Please refer to Figs. 1-2 The wire harness support of the utility model, including wire harness frame 1, wire harness frame 1 is equipped with lead frame 2, wire harness frame 1 and lead frame 2 are all equipped with wire groove 3, wire harness frame 1 and lead frame 2 are distributed with several binding holes 6 in wire groove 3, the side of wire harness frame 1 is equipped with several nesting holes 4, the nesting hole 4 is penetrated by a bolt.

[0024] The wire harness support is mainly used for managing and protecting cables or wires, preventing them from being damaged by external environment, and ensuring that they are reasonably and neatly arranged inside the equipment. The utility model relates to a specially designed wire harness support, including wire harness frame 1 and lead frame 2, both of which are equipped with wire groove 3 and binding hole 6, facilitating the fixation and management of wires.

[0025] Multi-directional wire harness fixing and guiding function

[0026] The main structure of wire harness frame 1 forms a continuous channel through wire groove 3, which is used for accommodating wire harnesses of different specifications, and the smooth design of the inner wall can reduce the abrasion of wire harnesses. Lead frame 2 is vertically fixed on the side of wire harness frame 1, and wire harness branching guidance is realized through the vertically distributed wire groove 3, avoiding the cross winding of multiple wire harnesses. Binding holes 6 are distributed in wire groove 3 and wire slope 5, and wire harnesses are fixed by binding tape at multiple points to prevent displacement of wire harnesses caused by vehicle vibration.

[0027] Modular installation and dynamic adaptability

[0028] Nesting holes 4 are arranged at both ends and the middle of wire harness frame 1, and the support is fixed on the pre-installed position of the vehicle body through the bolt penetrating the nesting hole 4, realizing the rigid connection of the support and the vehicle body. The groove 7 is arranged opposite to the nesting hole 4, providing additional space for wire harnesses to avoid extrusion and abrasion of wire harnesses caused by the bolt structure. The vertical multi-group design (≥2) of lead frame 2 can adapt to different wire harness layout requirements, such as shunt management of trunk power lines and rear seat entertainment wire harnesses.

[0029] Working principle of preferred technical scheme

[0030] Vertical layered design of lead frame 2

[0031] The lead frame 2 is connected perpendicularly to the wire harness frame 1 at 90°, forming a "T" type or "cross" type structure. The wire groove 3 of each lead frame 2 is independently layered, and the branch wire harness is isolated and fixed through the cable tie hole 6, avoiding electromagnetic interference between the high-voltage wire harness and the signal wire harness. This design also allows the wire harness to extend in different directions, adapting to the irregular space of the vehicle panel structure.

[0032] Mechanical synergy of nested hole 4 and groove 7

[0033] The nested hole 4 adopts at least three symmetrical distributions (two ends + middle), and the wire harness frame 1 is pressed tightly to the surface of the vehicle body by the pre-tightening force of the bolt, inhibiting the shaking of the support. The groove 7 is symmetrically arranged with the bolt, providing additional wire harness movement space, avoiding the extrusion and wear of the wire harness caused by the bolt structure, and the groove 7 can also be filled with elastic materials (such as rubber pads), further absorbing high-frequency vibration energy.

[0034] Damage prevention optimization of wire slope 5

[0035] The wire slope 5 is arranged at the end of the wire harness frame 1, and the inclination angle (preferably 30°-45°) allows the wire harness to smoothly transition when entering the support, reducing the risk of shearing of the wire harness outer skin at sharp edges. The cable tie hole 6 on the slope surface is linearly arranged, allowing the cable tie to be fixed obliquely along the wire harness, enhancing the binding force of the wire harness at the bending part.

[0036] The material of the wire harness frame 1 and the lead frame 2 in the technical solution is preferably PA66-GF30 nylon containing glass fiber and other materials for automobile manufacturing.

[0037] In the technical solution, the injection molding type of the obvious position of the wire harness frame 1 is marked to avoid misuse, and the product batch marked on the wire harness frame 1 can be effectively tracked, so that the batch can be locked in time once a problem is found.

[0038] Detailed workflow of the patent technical solution

[0039] Support positioning: according to the wire harness layout requirements of the vehicle body, the installation position of the wire harness frame 1 is selected, the nested hole 4 is aligned with the pre-set screw hole of the vehicle body, and the installation position of the support is ensured to adapt to the wire harness direction;

[0040] Rigid fixation: the bolt passes through the nested hole 4 and is screwed into the screw hole of the vehicle body, and a pre-set tightening force (such as 10-15 N·m) is applied through a torque wrench, realizing the gapless connection of the support and the vehicle body, and inhibiting low-frequency vibration;

[0041] Wire arrangement: the main wire harness is embedded into the wire groove 3 of the wire harness frame 1, and the branch wire harness is introduced into the vertical wire groove 3 of the lead frame 2, realizing layered management of the wire harness and avoiding sharp edge contact of the panel;

[0042] The cable tie is locked, the nylon cable tie is used to pass through the cable tie hole 6 to bind the wire harness, the cable tie lock is located outside the wire groove 3, multiple point dynamic binding is provided, small displacement of the wire harness is allowed but the wire harness is prevented from falling out;

[0043] The bending protection is achieved by fixing the inclined cable tie at the wire slope 5 and reserving the wire harness bending radius (≥5 times the wire diameter), so that the risk of fatigue damage of the wire harness caused by bending is reduced.

[0044] Although the embodiments of the utility model have been shown and described, it can be understood by those of ordinary skill in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, the scope of the utility model is defined by the appended claims and their equivalents.
