Description

Technical Field

[0001] This utility model relates to the field of aircraft technology, specifically to a multi-faceted fixing bracket for an electric aircraft wiring harness. Background Technology

[0002] Currently, as a new type of short-to-medium-range air transportation, eVTOL (Electric Vertical Takeoff and Landing) aircraft have achieved near-zero emissions while possessing advantages such as high safety, low noise, low manufacturing cost, and low operating cost. Therefore, they have attracted widespread attention from aerospace companies, the automotive industry, the transportation industry, governments, the military, and academia. Furthermore, eVTOL aircraft also feature safety and reliability (no explosions or fuel leaks), simple structure, ease of operation, good maintainability / low cost, and good economic efficiency.

[0003] Existing electric aircraft wiring harness fixing methods mostly use cable tie bases and cable ties for fixing. In high-vibration areas, the bonded cable tie bases may fall off. At the same time, the fixing components are mostly fixed on a single plane. At the intersection of the wiring harness, the wiring harness is prone to interference and friction, causing the wiring harness to wear. When connecting with clamps, a bracket nut and screw are often used together, which makes the installation process complicated.

[0004] Chinese utility model patent with announcement number CN207053136U and application number 201720872743.7 discloses a fixing structure for high current cables in aircraft. Its connection structure is complex and inconvenient to maintain. It cannot be installed at multiple angles. When installing complex lines, it is easy to cause the cable to become tangled, which affects the service life of the cable.

[0005] Therefore, we propose a multi-faceted fixing bracket for electric aircraft wiring harnesses to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a multi-faceted fixing bracket for electric aircraft wiring harnesses. It features multiple wiring routes to avoid wiring harness interference. At the same time, the integrated structure of the bracket optimizes weight while ensuring the strength of the bracket. This solves the problems of not being able to install wiring harnesses at multiple angles and the ease with which wiring harnesses can become tangled and affect their service life when installing complex wiring.

[0008] (II) Technical Solution

[0009] To achieve the aforementioned multiple wiring routing, avoid wire harness interference, and ensure high strength, this utility model provides the following technical solution: a multi-faceted fixing bracket for electric aircraft wire harnesses, comprising a bracket body, which can be a high-strength steel structure. The bracket body is formed into a multi-faceted structure by bending, generally a three-faceted structure, including a Z-shaped structure and a U-shaped structure. The multi-faceted structure includes a first fixing surface, a second fixing surface, and a third fixing surface. The second fixing surface forms an installation angle with the first and third fixing surfaces. When the multi-faceted structure is a Z-shaped structure, the second fixing surface forms a first installation angle with the first fixing surface, the angle of which is 30°-120°. A second mounting angle is formed between the fixing surface and the third fixing surface, and the angle of the second mounting angle is 30°-120°; when the multi-faceted structure is a U-shaped structure, a third mounting angle is formed between the second fixing surface and the first fixing surface, and the angle of the third mounting angle is 60°-120°; a fourth mounting angle is formed between the second fixing surface and the third fixing surface, and the angle of the fourth mounting angle is 60°-120°; by setting 30°-120° and 60°-120°, the installation direction of the wire harness can be provided to the maximum extent, while avoiding interference between the first fixing surface, the second fixing surface and the third fixing surface, and the mounting angle matches the fixing angle of the wire harness.

[0010] The first fixing surface has a bracket fixing hole, and the bracket body is fixed to the machine body structure by screws. The second fixing surface and the third fixing surface are both provided with fixing structures, which are used to fix the wire harness.

[0011] As a further optimization of this utility model: both the second fixing surface and the third fixing surface are provided with bracket weight reduction holes, which can optimize the weight while ensuring the strength of the bracket.

[0012] As a further optimization of this utility model: both the second fixing surface and the third fixing surface are provided with mounting holes. The fixing structure is fixedly mounted on the bracket body through the mounting holes. The fixing structure includes a clamp. The mounting holes are used to fix the clamp to the bracket body with screws. The fixing structure is fixed to the second fixing surface and the third fixing surface with screws.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a multi-faceted fixing bracket for electric aircraft wiring harnesses, which has the following advantages:

[0015] 1. This multi-faceted fixing bracket for wire harnesses, through its dual-mounting-plane structure, provides an independent two-dimensional fixing space for cross-routing wires. This avoids interference and friction between wire harnesses with different routes, optimizes the wire harness layout, and improves the standardization and safety of wire harness installation.

[0016] 2. This multi-faceted fixing bracket for the wire harness utilizes a connection scheme of rivet nuts and screws to combine the bracket with clamps. The pre-installed rivet nuts form an integrated structure with the bracket, requiring only one-sided screw tightening of the clamps during installation. This reduces installation steps, improves production efficiency, and lowers operational difficulty.

[0017] 3. The multi-faceted fixing bracket for this wiring harness utilizes finite element analysis to optimize its structure, incorporating weight-reducing holes in non-load-bearing areas. This achieves weight optimization while maintaining bracket strength. It meets the requirements of electric aircraft for lightweight and high-strength components, improving structural economy while satisfying reliability standards. Attached Figure Description
