[0002] In modern engine design, the complexity and density of electrical systems are continuously increasing, leading to higher requirements for wire management. Traditional wire harness management and fixing methods often cannot meet these needs, with various shortcomings:

[0003] Wire chaos and looseness: Traditional wiring methods often rely on simple binding or basic clamps for fixing, which can easily lead to wires being haphazardly stacked together, not only occupying a large amount of space, but also increasing the risk of mutual interference between wires, reducing system reliability and maintenance convenience.

[0004] Lack of structural strength: Many existing wire harness support designs are relatively simple, lacking structural strength, especially in high-vibration and high-temperature environments such as engine compartments, where wires are easily damaged due to loose supports, affecting the normal operation of electrical systems.

[0005] Installation inconvenience: Some existing wire harness management systems require complex tools and steps during installation, increasing the difficulty and time cost of work. In addition, these systems often lack the ability to adjust flexibly, making it difficult to adapt to different wiring needs.

[0026] 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 protection scope of the utility model.

[0027] Please refer to Figures 1-4 The fixed slot type engine in-cylinder wire harness support of the utility model, including support body 1, inlay 3 and tie hole 5, support body 1 is equipped with several lead frames, the lead frame and inlay 3 are integrated structure with support body 1, the lead frame and support body 1 are equipped with wire storage groove, several tie holes 5 are distributed on the wire storage groove, inlay 3 is equipped with nested hole 4.

[0028] The fixed slot type engine in-cylinder wire harness support is designed to optimize the wire management in the engine compartment, to ensure that the wire can still maintain stability and order under high vibration and high temperature environment. Support body 1, inlay 3 and tie hole 5 jointly provide a firm and flexible solution.

[0029] Modular wire harness fixation and anti-vibration design

[0030] Support body 1 adopts high-strength aluminum alloy casting, and the surface is provided with wire storage groove for accommodating engine in-cylinder wire harness such as ignition coil wire and sensor wire. The lead frame and inlay 3 are connected with support body 1 by integrated forming process to form a rigid structure. The tie holes 5 distributed in the wire storage groove are fixed in multiple directions by nylon tie, to inhibit the displacement of wire harness caused by high-frequency vibration of the engine.

[0031] Nested mechanical locking and heat dissipation optimization

[0032] Inlay 3 is arranged on both sides of support body 1, and nested hole 4 penetrates through the bolt to realize the rigid connection of the support and the engine cylinder. The pre-tightening force of the bolt makes support body 1 closely adhere to the surface of the cylinder, and the engine heat is conducted through metal contact to avoid the aging of the wire harness due to local high temperature.

[0033] Working principle of preferred technical scheme

[0034] Bilateral symmetrical layout of inlay 3

[0035] The inlay 3 is distributed on both sides of the support body 1, the nested hole 4 is symmetrically designed, such as left and right, the bolt is screwed into the preset screw hole of the engine cylinder to form four-point fixation, evenly disperses the engine vibration energy, and prevents deformation caused by unilateral stress concentration of the support.

[0036] Multi-stage protection of wire slope 2

[0037] At least two wire slopes 2 are arranged on one side of the support body 1, the inclination angle is 25°-40°, and the surface cable tie hole 5 is staggered. When the wire harness passes through the slope, the cable tie is locked along the slope, the bending angle of the wire harness is reduced (≥6 times the wire diameter bending radius), and at the same time, the slope structure guides the wire harness away from the high temperature area of the cylinder.

[0038] The lead frame is of a split structure (strip-shaped frame 7 and bent frame 6).

[0039] The bent frame 6 is L-shaped or U-shaped, is arranged at intervals with the strip-shaped frame 7 (the interval is preferably 10-15 mm), forms a wire harness layered channel, avoids friction interference of multiple wire harnesses, at the same time, utilizes the gap to improve the heat dissipation efficiency, the buckle 8 arranged at the surface is used for quickly fixing the wire harness branch, the interval of the buckle 8 (such as 15-20 mm) is adapted to different wire diameters, and a silica gel buffer layer is arranged on the surface of the buckle 8.

[0040] The buffer gradient 9 is arranged on the strip-shaped frame 7: the thickness gradually changes from the root to the top of the strip-shaped frame 7 (such as 1.5 mm→0.5 mm), and gradual pressure is provided when the wire harness is locked, so that the wire harness outer skin is prevented from being cut.

[0041] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled 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, and the scope of the utility model is defined by the appended claims and their equivalents.
