[0002] In eVTOL aircraft design, distributed power units are typically arranged in different areas to achieve an efficient aerodynamic layout. While this distributed architecture brings advantages in maneuverability and redundancy safety, it also results in a highly complex overall cabling system, requiring the cabling network to cover a large area. This places stringent requirements on lightweight design of the wiring harnesses, electromagnetic compatibility, and physical protection.

[0003] Currently, most aircraft wiring racks are simply designed, serving only to support cables without considering the classification and organization of different functional cables. In actual wiring, power lines, signal lines, communication lines, and other cables are intertwined haphazardly, like a tangled mess on the wiring rack. This forces maintenance personnel to spend a lot of time and effort to sort out these messy cables. The messy cables can also become tangled, leading to excessive heat accumulation and reduced current carrying capacity. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a wiring fixing frame, which arranges the wires according to a preset path and position by setting a first wire management hole, a second wire management hole and a fixing hole, increases the spacing between the wires, reduces signal interference caused by electromagnetic induction, reduces the heat accumulation effect of bundled cables and the excessive temperature rise that leads to a decrease in current carrying capacity, and ensures the accuracy of signal transmission.

[0020] The beneficial effects of this utility model are:

[0021] This invention features multiple first cable management holes, multiple second cable management holes, and fixing holes on a cabling bracket. Cables with different functions pass through these holes respectively, allowing them to be arranged according to preset paths and positions. This prevents cables from becoming tangled or piled up haphazardly. The different cable management holes facilitate organization, resulting in a cleaner space and making it easier for maintenance personnel to quickly locate the corresponding cables. Furthermore, separating different types of cables through different management holes increases the spacing between power cables, suppressing heat buildup and temperature rise, and ensuring stable current carrying capacity.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Figure 1 A schematic diagram of the wiring bracket in this utility model is shown. Figure 2 It shows Figure 1 Enlarged view of point A in the image. Figure 3 It shows Figure 1 Enlarged view of point B in the image. Figure 4 It shows Figure 1 Enlarged view of point C in the image. Figure 5 This is a front view schematic diagram of the wiring bracket in this utility model. Figure 6 A schematic diagram of the base structure in this utility model is shown. Figure 7 The diagram shows the structure of the outer casing of this utility model. The wiring fixing bracket includes: a first assembly block 1, a second assembly block 2, and a base 3. The base 3 is provided with a plurality of first circular grooves 31 and a plurality of second circular grooves 32. One side of the first assembly block 1 is recessed to form a plurality of third circular grooves 11 that match the first circular grooves 31. One side of the second assembly block 2 is recessed to form a plurality of fourth circular grooves 21 that match the second circular grooves 32. Any first circular groove 31 and the corresponding third circular groove 11 cooperate to form a first cable management hole 4. Any second circular groove 32 and the corresponding fourth circular groove 21 cooperate to form a second cable management hole 5. One side of the first assembly block 1 is provided with a fifth circular groove 12. One side of the second assembly block 2 is provided with a sixth circular groove 22. The fifth circular groove 12 and the sixth circular groove 22 cooperate to form a fixing hole 6. That is, the fixing hole 6 is located in the middle of the overall panel formed by the first assembly block 1 and the second assembly block 2.

[0033] In this embodiment, the base 3 is provided with two first circular grooves 31 and two second circular grooves 32. The first assembly block 1 is provided with two third circular grooves 11 corresponding to the first circular grooves 31, and the second assembly block 2 is provided with two fourth circular grooves 21 corresponding to the second circular grooves 32. The two first circular grooves 31 and the two third circular grooves 11 are respectively paired to form two first cable management holes 4, and the two second circular grooves 32 and the two fourth circular grooves 21 are respectively paired to form two second cable management holes 5. The two first cable management holes 4, the two second cable management holes 5, and the fixing holes 6 are respectively used to carry different cables, and the cables pass through different... Different cable management holes, where cables with different functions pass through separate holes, allow various cables to be arranged according to a preset path and position, preventing them from becoming tangled and piled up haphazardly. This facilitates organization through different holes, resulting in a cleaner space and significantly improved visual appeal. Furthermore, separating different types of cables through different holes increases the spacing between power cables, suppressing heat buildup and temperature rise, and ensuring stable current carrying capacity. Simultaneously, separating signal and power cables through different holes increases the spacing between them, reducing signal interference caused by electromagnetic induction. Both mechanisms work together to ensure the accuracy of signal transmission and improve the reliability of the entire system.

[0034] Furthermore, one end of the base 3 has a mounting step 33, on which a first connecting hole 331 is provided. The base 3 is connected to the first assembly block 1 based on the first connecting hole 331. In this embodiment, the mounting step 33 is used to engage the wiring bracket 100 with the corresponding position. That is, when the wiring bracket 100 is installed on the aircraft shell, the mounting step 33 can engage with the corresponding mounting groove on the shell, increasing the contact area between the mounting step 33 and the aircraft shell. Therefore, the base 3 can be fixed to the aircraft shell, reducing the risk of the wiring bracket 100 detaching from the corresponding position during use, and facilitating the stable installation of the wiring bracket 100 in the corresponding position.

[0035] Furthermore, the other end of the base 3 extends to one side to form a fixing boss 34. The fixing boss 34 is provided with a second connecting hole 341, and the base 3 is connected to the second assembly block 2 based on the second connecting hole 341. In this embodiment, the fixing boss 34 is used to engage the wiring fixing bracket 100 with the corresponding position. That is, when the wiring fixing bracket 100 is installed on the aircraft shell, the fixing boss 34 can be inserted into the corresponding mounting slot on the aircraft shell, so that the base 3 can be fixed to the shell. The fixing boss 34 can engage with the corresponding position of the fixing boss 34, ensuring that the base 3 can be locked in the corresponding position, reducing the risk of the wiring fixing bracket 100 disengaging from the corresponding position during use, and facilitating the stable installation of the wiring fixing bracket 100 in the corresponding position.

[0036] Furthermore, a high-temperature resistant liner 8 is provided inside the first cable management hole 4, and a high-temperature resistant liner 8 is provided inside the second cable management hole 5. In this embodiment, multiple wires need to pass through the first cable management hole 4 or the second cable management hole 5, and these multiple wires will emit a large amount of heat during operation. The high-temperature resistant liner 8 can effectively block the conduction of heat to the connection hole and the mounting bracket substrate, reducing the risk of material softening, deformation or failure caused by local high temperature. This helps to reduce stress concentration in the metal structure due to thermal expansion differences, which can lead to cracks or fractures, and extends the service life of the wiring bracket 100.

[0037] Furthermore, the high-temperature resistant liner 8 is made of high-temperature resistant PEEK material. PEEK is a semi-crystalline polymer material whose molecular chains consist of repeating ether bonds, ketone bonds, and aromatic rings. Strong van der Waals forces and dipole-dipole interactions exist between the PEEK molecular chains, further enhancing the material's thermal stability. This structure endows PEEK material with high-temperature resistance. Secondly, in high-temperature air, PEEK is not easily oxidized and degraded, and a brittle oxide layer does not form on its surface, thus maintaining its mechanical properties. This helps reduce stress concentration caused by thermal expansion differences in the metal structure, leading to cracks or fractures, and extends the service life of the wiring bracket 100.

[0038] Furthermore, the first wire guide hole 4 has a first rounded corner 41 on its edge, the second wire guide hole 5 has a second rounded corner 51 on its edge, and the fixing hole 6 has a third rounded corner 61 on its edge. In this embodiment, the edges of the three types of holes are all rounded. The rounded corners make the contact surface smoother and more continuous, dispersing the pressure originally concentrated at the corners to a larger area, thereby greatly reducing local pressure. This avoids the wire and hole contact being concentrated at sharp corners at right angles, which would generate large local pressure and cause severe friction between the wire sheath and the hole edge. This helps to delay the wear of the wire sheath, reduce the risk of scratches, damage, or even peeling of the sheath, and also reduce the gradual weakening of the wire's mechanical strength during long-term use, increasing the risk of wire breakage and extending the wire's service life.

[0039] Furthermore, the first assembly block 1 extends away from the base 3 on one side to form a first connecting portion 13, and the first connecting portion 13 is provided with a first assembly hole 131; the second assembly block 2 extends away from the base 3 on one side to form a second connecting portion 23, and the second connecting portion 23 is provided with a second assembly hole 231; the first assembly hole 131 and the second assembly hole 231 are interconnected based on the connecting component 7. In this embodiment, the first connecting portion 13 provides a position for the first assembly block 1 to connect with the second assembly block 2, and similarly, the second connecting portion 23 provides a position for the second assembly block 2 to connect with the first assembly block 1. The first assembly hole 131 is located at the center of the first assembly block 1, and the second assembly hole 231 is located on the second assembly block 2 at a position corresponding to the first assembly hole 131. When the first assembly hole and the second assembly hole are aligned, the connecting component 7 can lock the first assembly block 1 and the second assembly block 2 through the first assembly hole 131 and the second assembly hole 231, reducing the risk of the first assembly block 1 and the second assembly block 2 disengaging, and helping to ensure the structural stability of the wiring fixture 100.

[0040] Furthermore, a gasket is provided on the outer side of the first connecting portion 13, and a gasket is provided on the outer side of the second connecting portion 23. In this embodiment, when the first assembly block 1 and the second assembly block 2 are installed together, the inner side of the first connecting portion 13 and the inner side of the second connecting portion 23 are in contact, that is, the outer side of the first connecting portion 13 and the outer side of the second connecting portion 23 are visible to the operator. A first gasket 14 is provided on the outer side of the first connecting portion 13, and the first gasket 14 is correspondingly distributed at the first assembly hole 131. A second gasket 24 is provided on the outer side of the second connecting portion 23, and the second gasket 24 is correspondingly distributed at the second assembly hole 231. The first gasket 14 and the second gasket 24 are used to increase the friction between the connecting assembly 7 and the wiring fixture 100. Since the connecting assembly 7 connects the first assembly block 1 and the second assembly block 2, when the connecting assembly 7 is locked, the gasket is deformed by the force of the connecting assembly 7, thereby increasing the contact area between the gasket and the wiring fixture 100 and the connecting assembly 7, thus increasing the friction between the gasket and the wiring fixture 100 and the connecting assembly 7. This avoids the risk of the connecting assembly 7 loosening on its own during use, which could cause the first assembly block 1 and the second assembly block 2 to detach. It also helps to improve the connection strength between the first assembly block 1 and the second assembly block 2 and ensures the structural stability of the wiring fixture 100.

[0041] Furthermore, the wiring bracket 100 is made of metal. In this embodiment, the wiring bracket 100 is preferably made of a composite material of various metals, including aluminum alloy, titanium alloy, stainless steel, and other metals. Therefore, the wiring bracket 100 has the properties of multiple metals. Among them, aluminum has a low density, and aluminum alloy products are lightweight, which can significantly reduce the weight of the wiring bracket 100. Stainless steel can form a dense chromium oxide film on its surface, which can effectively prevent further oxidation of metal ions, resist chemical corrosion and electrochemical corrosion, and can be used for a long time without rusting in humid or corrosive environments. Titanium alloy has a higher operating temperature than aluminum alloy, and can work for a long time at 450-500℃. It can still maintain high specific strength in the range of 150-500℃. Therefore, the wiring bracket 100 has the properties of being lightweight, corrosion-resistant, and high-temperature resistant.

[0042] This utility model also proposes an eVTOL aircraft, which includes: multiple wiring brackets 100 and a housing 200, wherein the multiple wiring brackets 100 are sequentially fixed to the bottom of the housing 200. In this embodiment, four wiring brackets 100 are provided on the power system, and the four wiring brackets 100 are sequentially installed on the bottom of the housing 200, and the four wiring brackets 100 are located on the same straight line, that is, the connection holes of each wiring bracket 100 are located at the same height and on the same straight line, which facilitates the installation of the wires on the power system along the preset position. When the cable is installed on the wiring bracket, the cable can be fixed along the preset path determined by these connection holes at the same height and on the same straight line, so that the cable maintains a stable tension distribution and fixed positional relationship in the entire wiring system, effectively preventing signal interference, poor contact and other problems caused by cable position deviation or loosening, and ensuring that the entire wiring system can operate stably and long-term according to the preset requirements.

[0043] In summary, this utility model, by providing multiple first cable management holes, multiple second cable management holes, and fixing holes on the wiring bracket, allows cables with different functions to pass through these holes respectively. This enables various cables to be arranged according to preset paths and positions, preventing them from becoming tangled and piled up haphazardly. The different cable management holes facilitate organization, resulting in a cleaner space and making it easier for maintenance personnel to quickly locate the corresponding cables. Furthermore, separating different types of cables through different management holes increases the spacing between power cables to suppress heat accumulation and temperature rise, ensuring stable current carrying capacity. Simultaneously, separating signal and power cables through different management holes increases the spacing between them, reducing signal interference caused by electromagnetic induction. Both of these features work together to ensure the accuracy of signal transmission and improve the reliability of the entire system.
