Preferably, the corner joint 23 is machined from 7050-T7451, 7075-T6 hard aluminum alloy sheets or bars.

[0051] The first door panel component 18 and the side panel 17 are respectively arranged on the front and one side of the outer frame 16, and serve as observation windows without participating in load bearing.

[0052] In this embodiment, six layers of support beams 9 are arranged from bottom to top in the first electronic equipment rack 4. The support beams 9 are made of 7050-T7451 hard aluminum alloy profile. Considering the standard chassis height of 194mm, the thickness of the bracket and the support beam is 34mm, about 32mm of heat dissipation and maintenance space needs to be reserved in the height direction of the chassis, so the layer height is set to 260mm. The layer height of individual layers is partially adjusted according to the changes of the support beams and other structures to ensure the heat dissipation and maintenance space above the equipment. The equipment on the same layer is evenly arranged, and the spacing is guaranteed to be more than 15mm to provide equipment heat dissipation space.

[0053] The first to fifth layers in the first electronic equipment rack 4 are used to fix and support electronic equipment, and a first transfer surface 14 is provided between the sixth layer support beam 9 and the top of the outer frame 16, which serves as the mounting surface of the circular connector plug 11 and bears the weight of the connector and part of the wire. When the connector plug on the integrated device connected to the aircraft is a rectangular connector plug, the first transfer surface 14 serves as the mounting surface of the rectangular connector plug, and the corresponding connector on the cable assembly is also a rectangular connector.

[0054] The utility model realizes the electrical connection between the equipment in the rack and the aircraft through the first transfer surface 14. A module mounting plate 15 is provided between the third-layer support beam 9 and the fourth-layer support beam 9 in the first electronic equipment rack 4, and the first wiring rod 19 is arranged on the same layer as the module mounting plate 15, and the first wiring rod 19 provides a wiring path and support for the cable, so that the wire harness is arranged according to the set path, which can effectively reduce the diameter of the wire harness, optimize the wiring harness laying path, and facilitate maintenance and repair. The first transfer surface 14, the module mounting plate 15 and the side panel 17 are all made of high-strength hard aluminum alloy 7075-O, and the processing method is sheet metal stamping and bending, and heat treatment to T62 state to improve hardness. The first wiring rod 19 rod frame is welded by 8mm hollow aluminum tube, and the base is machined by sheet material or bar material. When installing, the first transfer surface 14 and the module mounting plate 15 are both retracted 100mm inward along the rack, which reduces the space occupation of the maintenance channel by the cable turning radius on the one hand, and protects the module cable on the other hand.

[0055] In this embodiment, the side panel 17 is a hollow structure to facilitate heat dissipation and weight reduction in the rack.

[0056] In the embodiment of the utility model, the first bracket assembly 5 includes a bracket 24, a rear mounting plate 13, a bracket corner joint 25, a front gasket 26, a rear gasket 27, a spring positioning pin 28, a guide rail slide 29 and a locking device 30. The bottom of the bracket 24 is used to carry the chassis, and the two sides of the bracket 24 also have ribs for limiting the two sides of the chassis, so that the bracket 24 can guide and support the chassis equipment. The rear mounting plate 13 is fixed to the rear of the bracket 24 through the bracket corner joint 25, which is used to stop and limit the chassis equipment. Specifically, the rear mounting plate 13 extends vertically to the bottom of the bracket 24, and is riveted to the two side ribs of the rear of the bracket 24 through its two side edges through semicircular head rivets 31, wherein the bracket corner joint 25 is embedded between the 90-degree folded edges on both sides of the rear mounting plate 13 and the rear mounting plate body, and the semicircular head rivet 31 passes through the ribs of the bracket 24 and the ribs of the rear mounting plate 13 in sequence and then enters the bracket corner joint 25. In this embodiment, the height of the flanges on both sides of the front end of the bracket 24 is much smaller than the height of the flanges on both sides of the rear end, and the flanges on both sides of the rear end are hollow structures to prevent them from affecting the heat dissipation of the chassis equipment. Preferably, the bracket 24 and the rear mounting plate 13 are made of high-strength hard aluminum alloy 7075-O, processed by sheet metal bending, and heat treated to T62 state to improve hardness.

[0057] The upper surface of the bottom of the bracket 24 is also provided with a guide rail 29, which has a self-lubricating property and can effectively reduce the friction during the plugging and unplugging of the chassis device to avoid scratching the coating of the chassis device and the bracket. In this embodiment, the guide rail 29 is made of filled polytetrafluoroethylene and is glued to the surface of the bracket 24 by glue, and the glue is J-2005 glue.

[0058] The front edge of the bracket 24 is also provided with a downwardly folded flange structure 32 for marking the device logo to prevent the logo from being blocked. The bottom of the bracket 24 is also provided with a ventilation hole 33 to achieve natural cooling of the chassis equipment.

The above-mentioned front gasket 26 and rear gasket 27 are in contact with the support beam 9 when the first bracket assembly 5 is fixed, which can effectively improve the structural strength of the external connection position of the bracket.

[0061] The locking device 30 is used in conjunction with a pair of handle assemblies on the chassis device to achieve plug-in and lock assistance of the chassis device. In this embodiment, the locking device 30 includes a fixing portion fixed to the bottom of the front gasket 26, a support fixed to the front end of the fixing portion, and a pin 35 arranged on the support. The handle assembly includes a handle and a locking member 34 rotatably arranged on the handle, and the lower end of the locking member 34 has a locking hook 341 extending out of the handle assembly. The handle is provided with a groove 342 for accommodating the locking member 34 and a lever 36 for confining the locking member 34 in the groove 342. The lever 36 locks the locking member 34 through the locking hook thereon, and when the lever is pulled outward, the locking member 34 can be unlocked. When the chassis device is loaded into the first bracket assembly 5, the locking member 34 is in the initial position of unlocking and maintaining perpendicularity with the handle. When the chassis device moves to the position corresponding to the handle and the locking device 30, the lock hook 341 at the lower end of the locking member 34 is engaged with the pin 35. At this time, the locking member 34 is rotated upward to enter the groove 342 on the handle. In this process, since the lock hook 341 uses the pin 35 as a rotation fulcrum, the locking member 34 pushes the chassis device during the rotation process to be inserted into the rear mounting plate 13. When the locking member 34 is in the final position when it is completely inserted into the groove 342 and locked, the chassis device is inserted in place, and the handle assembly is locked by the cooperation of the lock hook 341 and the pin 35. That is, the locking device 30 of the utility model can cooperate with the handle assembly of the chassis device, and the chassis device is quickly inserted into place and locked by using the lever principle. When the chassis device needs to be pulled out, the lever 36 is pulled to push out the locking member 34, and then the locking member 34 is rotated downward to rotate the locking member 34 with the pin 35 as a fulcrum. Through the lever effect, the chassis device can be quickly pulled out. When the locking member 34 is rotated to be perpendicular to the handle, the chassis device is separated from the rear installation panel 13. At this time, the chassis device is pulled forward, and the locking member 34 is separated from the pin 35. In other embodiments of the utility model, the locking member can be locked with the handle through other locking structures.

[0062] The first bracket assembly 5 of the utility model is connected to the rectangular connector socket of the chassis device through the rectangular connector plug 10, so as to realize the reliable transmission of the onboard electronic equipment and the onboard electrical signal; through the cooperation of a pair of locking devices 30 and the handle assembly, the onboard electronic equipment is reliably fixed and quickly disassembled. In other embodiments of the utility model, the shape of the connector can be adjusted as needed, that is, the rectangular connector in the cable assembly can be replaced with a circular connector, and the first bracket assembly 5 has a circular connector adapted to the circular connector.

[0063] The first cable assembly 6 of the utility model is divided into three main channels according to the system function, wiring harness isolation and redundancy design, and each layer of cables is fixed by a wiring rod, which effectively reduces the diameter of the wiring harness, making the on-board cables simple, neat and easy to maintain. In this embodiment, the first cable assembly 6 includes components such as a rectangular connector plug 10, wires and cables 37, a circular connector plug 11, a wiring module 12, a clamp 38, a wiring terminal 39, a binding tape, a solder ring, a cable protective sleeve, and a marking heat shrink sleeve. Among them, the wires and cables 37 are used to realize the connection between the above-mentioned rectangular connector plug 10, the circular connector plug 11, the wiring module 12 and the wiring terminal 39, and the wires and cables 37 are fixedly installed on the first electronic equipment rack 4 by a clamp 38, and the clamp 38 can prevent the wiring harness from sliding or rotating. The material of the clamp 38 is a stainless steel hoop and a blue fluorosilicone rubber pad.

[0064] The rectangular connector plug 10 is mounted on the rear mounting plate 13 on the first bracket assembly 5, and is used to plug into the rectangular connector socket of the chassis equipment to achieve the switching of the signal line; the circular connector plug 11 is fixed on the first switching surface 14, and its plug-in end faces the opposite direction of the plug-in end of the rectangular connector plug 10, and the electrical connection with the aircraft is achieved by extending the plug-in end of the rear end face of the first switching surface 14; the wiring module 12 is fixed on the module mounting plate 15, and is used to achieve the wiring and switching within the equipment and the signal connection between different systems. The first cable assembly 6 of the utility model realizes the electrical connection between the airborne equipment and the aircraft, and between the equipment and the equipment through the wiring module 12 and the circular connector 10. The wiring terminal 39 is arranged at the end of the wire and cable 37, and is used to overlap with the frame structure to provide the necessary low-impedance path between the cable and the base structure.

[0065] See also Figure 8-17, which is a schematic diagram of the structure of the integrated device of the second embodiment of the utility model. In this embodiment, since the integrated device in this embodiment performs different tasks from the integrated device in the first embodiment, the installed electronic equipment and the transmitted electrical signals are different. In this embodiment, the integrated device includes a second electronic equipment rack 40, a second bracket assembly 41 and a second cable assembly 42, wherein the structure of the second bracket assembly 41 is basically the same as that of the first bracket assembly 5, and the difference between the two is only in the number, size, opening size of the adapter connector and the change of the installation position to adapt to different electronic equipment numbers, sizes and transmission signals.

[0066] The second electronic equipment rack 40 includes an outer frame, a support beam, a second transfer surface 43, a second door panel 44 and a second wiring rod 45. The outer frame and the support beam are basically consistent with the outer frame and the support beam structure of the first electronic equipment rack 4. That is, the second electronic equipment rack 40 is similar in structure to the first electronic equipment rack 4. The difference between the two is that the second transfer surface 43 is provided with a circular connector plug mounting hole and a wiring module mounting hole at the same time, that is, the second electronic equipment rack 40 does not have a special module mounting plate, and the wiring module is fixed on the second transfer surface 43. The position of the second wiring rod 45 changes with the change of the fixed position of the wiring module, and is also arranged at the same level as the second transfer surface 43. In this embodiment, it is arranged between the sixth-level support beam 9 and the top of the outer frame.

[0068] In this embodiment, the second electronic equipment rack 40 and the first electronic equipment rack 4 have the same structure and the same material selection. Considering the standard chassis height of 194mm, the bracket and support beam thickness of 34mm, it is necessary to leave about 32mm of heat dissipation and maintenance space in the chassis height direction, so the layer height of the second electronic equipment rack 40 is set to 260mm. The layer height of individual layers is partially adjusted according to the changes of the support beam and other structures to ensure the heat dissipation and maintenance space above the equipment. The spacing between devices on the same layer is evenly arranged, and at the same time, the spacing of more than 15mm is guaranteed to provide equipment heat dissipation space.

[0069] In this embodiment, the second electronic equipment rack 40 is open at both sides without side panels, so that the second electronic equipment rack 40 can be placed side by side with other equipment racks, while enhancing its heat dissipation capacity and reducing its weight.
