Description

Technical Field

[0001] This utility model relates to structural components of electrical equipment, specifically a composite integrated mounting bracket. Background Technology

[0002] With the rapid development of modern industry and defense technology, electronic equipment is constantly evolving towards intelligence, integration, localization, and standardization. In this process, the architecture of electronic equipment has also undergone a fundamental transformation from "single platform splicing" to "system integration." As the key structure supporting these devices, the mounting platform has also evolved from a single-function independent structure into a highly integrated integrated mounting rack.

[0003] However, while this integration trend brings improved system performance, it also introduces significant drawbacks: the structure of integrated mounting racks is becoming increasingly complex, and their weight accounts for a larger proportion of the overall equipment weight. This creates a sharp contradiction with the increasingly stringent lightweight design requirements in fields such as modern aerospace vehicles where weight is extremely sensitive.

[0004] Furthermore, traditional plate-type load-bearing structures also face significant challenges for electronic equipment components mounted on mounting racks. Traditional plate structures have inherent limitations in weight control, making it difficult to achieve effective weight reduction while maintaining structural strength. Utility Model Content

[0005] Therefore, in order to solve the above-mentioned shortcomings, this utility model provides a composite integrated mounting bracket, which is formed by a mesh plate formed by the intersection of multiple ribs, and the ribs are formed by a skin and a porous hollow support part that extends into three-dimensional space and is filled in the skin. While meeting the strength requirements, it effectively solves the contradiction between system integration and lightweight design, and overcomes the inherent defects of traditional plate structures in weight reduction, so that the structure achieves the ultimate lightweight.

[0006] Specifically, a composite integrated mounting bracket includes two vertically arranged uprights, an equipment support plate horizontally arranged between the two uprights, and an equipment mounting backplate fixedly connected to the uprights on one side of the equipment support plate. The upright plate and / or the back plate of the electrical equipment and / or the support plate of the electrical equipment are mesh plates formed by the intersection of multiple ribs. The ribs include porous hollow support parts extending into three-dimensional space and / or porous hollow support parts of the skin. The porous hollow support parts of the skin include the skin and porous hollow support parts filled in the skin.

[0007] Optionally, the upper end of the upright plate is provided with a connecting part. The connecting part is a column fixed to the upright plate or an upward-opening U-shaped connecting plate, the upper end of which is a connection point.

[0008] Optionally, an electrical equipment support plate is also provided laterally on the outer side of the upright plate. The number, position, and height of the electrical equipment support plates on the outer sides of the two upright plates are the same.

[0009] Preferably, there are three electrical equipment support plates between the two upright plates, and three electrical equipment support plates on the outer side of each upright plate.

[0010] Optionally, the electrical equipment's aviation plug backplate has several aviation plug interface holes.

[0011] This utility model has the following advantages: This invention relates to a composite integrated mounting rack. Based on the installation method and strength requirements of the structure, and the equivalent load and constraints, the integrated mounting rack is optimized using topology optimization. The optimal force transmission path is determined for the support plate, upright plate, and back plate of the integrated mounting rack. Redundant and inefficient material areas are eliminated, forming a mesh plate to achieve the initial lightweighting goal.

[0012] The porous, hollowed-out support is a lattice structure, which is a porous solid structure formed by the periodic extension of tiny, ordered unit structures in three-dimensional space. It has extremely lightweight characteristics (the porosity of the lattice structure is very high, which can significantly reduce the amount of material used and achieve significant weight reduction); high specific strength / specific stiffness characteristics (the lattice structure can provide excellent strength and stiffness with very light weight, and is extremely efficient); and excellent energy absorption characteristics (when subjected to vibration and impact, the lattice structure will slowly absorb energy through the layer-by-layer buckling and deformation of its units). Therefore, the lattice structure is the optimal solution for further weight reduction.

[0013] In this application, the low-stress area is taken as the target area for further lightweight design. The stress or displacement results of the target area are used as the boundary conditions of the lattice design. The cell size (rod diameter, wall thickness, envelope size) of the lattice structure is used as a variable to form a non-uniform network with gradient changes in the lattice structure to fill and replace the target area, and merged with the reserved area (medium-high stress area, installation point features, functional features) of the topology optimization structure.

Detailed Implementation

[0015] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0016] In this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, without necessarily requiring or implying any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0017] As described in the background section, traditional plate-type load-bearing structures also face significant challenges for electronic device structural components mounted on mounting racks. Traditional plate structures have inherent limitations in weight control, making it difficult to achieve effective weight reduction while maintaining structural strength.

[0018] Based on the above shortcomings, such as Figures 1-4 As shown, this embodiment provides a composite integrated mounting bracket, including two vertically arranged upright plates 100, an equipment support plate 200 horizontally arranged between the two upright plates, and an equipment mounting backplate 300 fixedly connected to the upright plates 100 on the back side of the equipment support plate 200. The upright plate and / or the back plate of the electrical equipment and / or the support plate of the electrical equipment are mesh plates formed by the intersection of multiple ribs. The ribs include a porous hollow support portion 120 extending into three-dimensional space and / or a porous hollow support portion of the skin. The porous hollow support portion of the skin includes a skin 110 and a porous hollow support portion 120 filled in the skin.

[0019] The aforementioned technical features, based on the installation method and strength requirements of the structure, are equivalently assigned loads and constraints. A topology optimization method is used to optimize the integrated mounting frame. Under this method, the optimal force transmission path is determined for the support plate, upright plate, and back plate of the integrated mounting frame, eliminating redundant and inefficient material areas to form a mesh plate, achieving the initial lightweighting goal. Simultaneously, the porous, perforated support section is a lattice structure. This lattice structure is a porous solid structure formed by the periodic extension of tiny, ordered unit structures in three-dimensional space. It possesses extreme lightweight characteristics (the porosity of the lattice structure is very high, significantly reducing material usage and achieving substantial weight reduction); high specific strength / specific stiffness characteristics (the lattice structure provides excellent strength and stiffness with extremely high efficiency while maintaining a very light weight); and excellent energy absorption characteristics (when subjected to vibration and impact, the lattice structure slowly absorbs energy through the layer-by-layer buckling and deformation of its units). Therefore, the lattice structure is the optimal solution for further lightweighting.

[0020] Meanwhile, the low-stress area is taken as the target area for further lightweight design. The stress or displacement results of the target area are used as the boundary conditions for the lattice design. The cell size (rod diameter, wall thickness, envelope size) of the lattice structure is used as the variable to form a non-uniform network with gradient changes in the lattice structure to fill and replace the target area, and merged with the reserved area (medium-high stress area, installation point features, functional features) of the topology optimization structure.

[0021] To connect this mounting bracket to aviation equipment, a connecting part 400 is provided at the upper end of the upright plate 100 via a fixed connection method (such as screw connection, welding, or integral molding); the connecting part is a column fixed to the upright plate or an upward-opening U-shaped connecting plate, the upper end of which is the connection point. The column or U-shaped connecting plate can be used to fix and install the electrical equipment mounting bracket.

[0022] To facilitate better installation of the electrical modules, in one embodiment, an electrical equipment support plate is laterally arranged on the outer side of the upright plate; the number and position of the electrical equipment support plates on the outer sides of the two upright plates are the same. Preferably, there are three electrical equipment support plates between the two upright plates, and three electrical equipment support plates on the outer side of each upright plate. By evenly arranging the electrical equipment support plates, the stability of the entire structure can be improved, and installing electrical equipment support plates on both sides can increase the number of electrical modules that can be installed, thus improving the concentration.

[0023] To facilitate the connection between the electrical module and the communication module, in one embodiment, the electrical equipment avionics connector backplane 300 has several avionics connector interface holes 301. These avionics connector interface holes allow for the installation of the avionics connector block, thereby facilitating communication between the electrical modules.

[0024] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
