[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0016] like Figure 1-4 As shown, this utility model provides a comprehensive equipment cabinet for a large civil aircraft, including: cabinet assembly 1, wire harness mounting bracket 2, separation panel 3, wire harness fixing plate 4, stair support 5, handrail support 6, equipment bracket 7, and cabinet panel 8, wherein: The separation panel 3, wire harness fixing plate 4, stair support 5, handrail support 6, and equipment bracket 7 are all installed on the cabinet assembly 1 by screw connections. Cabinet component 1 comprises a 6-layer rectangular frame, a truss structure consisting of columns, beams, and longitudinal beams made of a high-strength, lightweight alloy frame. The columns, beams, and longitudinal beams are joined together via machined slots on the front and rear beams and connected with bolts. Each layer uses U-shaped longitudinal beams connected to the front and rear columns. Each layer's bracket mounting beams (beams) are divided into front and rear mounting beams, designed in a U-shape to accommodate the installation of brackets, lap joints, nameplates, and other components. Furthermore, the cabinet is connected to the aircraft floor beams via bottom bolts, to the aircraft frame via lateral tie rods, and to the cockpit bulkhead via rear tie rods. The wire harness mounting bracket 2 includes a 4-layer aluminum alloy U-shaped beam, which is connected and fixed to the cabinet assembly via a triangular bracket; the mounting bracket is provided with multiple mounting holes for fixing clamps and wire harness binding installation; The separation panel 3 mates with the wiring harness connectors inside and outside the cabinet, providing an installation interface for the wiring harness connectors inside and outside the cabinet according to the electromagnetic isolation requirements and the safety requirements of the wiring installation; and to ensure that the connectors on the separation panel are accurately connected to the cables on the machine, the numbers of each connector on the separation panel are silkscreened on the connector mating surface, so that the personnel on the machine can quickly locate the position of the connectors on the separation panel. The wire harness fixing plate 4 provides a reliable installation and fixing point for the connection between the on-machine wire harness and the wire harness in the cabinet. The fixing plate is divided into upper and lower layers and is provided with multiple clamp mounting holes for fixing the wire harness, which can distribute the installation and laying of the wire harness. The stair support 5 is saddle-shaped, providing three reliable mounting points for the cockpit staircase; The handrail support 6 is cylindrical in shape, providing two reliable mounting points for the handrails entering the cockpit; The airborne equipment is installed on the equipment bracket 7 according to the mechanical interface. The equipment bracket 7 is provided with two forms according to the mechanical installation interface of the airborne equipment: quick-release bracket and pallet. They are fixed to the installation beam (bracket installation beam) of each layer 1 with bolts, and the distance between adjacent quick-release brackets is greater than 4.7mm.
[0017] Cabinet panel 8 is designed to prevent water droplets and condensation from splashing or dripping into the equipment cabinet. It includes a front panel, side panels, and a top cover. The front panel consists of an aramid paper honeycomb composite door panel, carbon fiber ventilation windows, and a handle. It is installed on the upright of cabinet component 1 using a quick-release lock. The side panels are carbon fiber louvers and are connected to cabinet component 1 using titanium alloy rivets. The top cover is an aluminum alloy plate and is connected to cabinet component 1 using rivets.
[0018] The dimensions and quantity of the stair support 5 are determined according to the installation location of the staircase.
[0019] The external dimensions of the handrail support 6 are set according to the size of the handrail and the installation location.
[0020] The quick-release bracket 7 is connected to the airborne equipment via a rear-pluggable rectangular connector. The rear-pluggable rectangular connector is fixed to the rear of the quick-release bracket via a connector housing. The front part is connected to the airborne equipment via a front locking device (Class A, Class B, Class C) to achieve reliable fixation and quick disassembly / removal.
[0021] For example, such as Figure 2 As shown, clamps used for installing different types of channel wire harnesses can be screwed onto the wire harness mounting bracket 2 through multiple mounting holes on the wire harness mounting bracket 2, and the wire harnesses can be fixed inside the clamps.
[0022] For example, such as Figure 3 As shown, the staircase can be installed on three staircase supports 5 by screw connection, and the two sides of the staircase are symmetrical to each other.
[0023] For example, such as Figure 4 As shown, the handrail rod can be inserted into the handrail support 6 from top to bottom, and fixed with screws passing through the handrail and the handrail support.
[0024] For example, such as Figure 5 As shown, the airborne equipment can be pushed into the quick-release bracket in the equipment bracket 7 according to its own mechanical interface form. The rear of the mounting bracket is connected to the airborne equipment through a rear-plug rectangular connector, while the front is reliably fastened to the equipment through different types of locking devices.
[0025] The above description merely illustrates the embodiments of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Furthermore, any parts of this utility model not described in detail are conventional techniques.
