[0033] The utility model is further described in detail below with reference to the accompanying drawings.

[0034] A multifunctional cabinet with high integration display switching, such as Figure 2 As shown, it includes a casing and an internal circuit, wherein the internal circuit is installed inside the casing. The elements of the utility model meet the requirements of a 19-inch rack-mounted cabinet and integrate multiple functional units.

[0035] like Figure 1 , Figures 5 to 13 As shown, the internal circuit includes a power supply unit C1, a display unit C2, a control unit C3, a switching unit C4, a CmaCast receiver C5, a CCTV receiver C6, a computer IC7 and a computer IIC8, wherein the power supply unit C1 is respectively connected to the display unit C2, the control unit C3, the switching unit C4, the CmaCast receiver C5, the CCTV receiver C6, the computer IC7 and the computer IIC8 for providing power, the switching unit C4 is connected to the display unit C2 for display output, the control unit C3 is connected to the switching unit C4 for keyboard and mouse input, the switching unit C4 is respectively connected to the computer IC7 and the computer IIC8, the computer IC7 is connected to the CmaCast receiver C5, and the computer IIC8 is connected to the CCTV receiver C6.

[0036] Among them, the specific reinforcement method of each unit is one-stage phase change, one-stage conduction, and one-stage air-cooled heat dissipation: the integrated aluminum alloy phase change cold plate is fixed tightly on the circuit board by screws. The phase change cold plate has three functions: first, it improves the resonance point of the module to ensure that the components meet the vibration requirements of military computers; second, through the high-K value thermal conductive material, the heat generated by the high-power components is quickly transferred to the thermal conductive plate; third, the phase change material inside the phase change cold plate can quickly transfer the heat from the hot end to the cold end; the locking device of the module further transfers the heat to the casing, and the forced air cooling fan on the casing drives the air flow through the internal air duct of the casing to take away the heat from the casing. This makes the whole machine meet the heat dissipation requirements while having moisture-proof, dust-proof, impact-resistant and vibration-resistant functions. Multiple reinforcements are used for the PCB board to enhance the rigidity of the PCB board. High-reliability connectors are used, and through finite element vibration analysis, the PCB natural frequency is designed to be above 120Hz to meet the rigid connection requirements of hierarchical structural parts. The cabinet adopts large-circulation forced air cooling to dissipate heat. The heat of each unit chassis is diffused to the internal space of the cabinet through the air. A low-noise axial flow fan is designed on the upper back of the cabinet to dissipate the heat inside the cabinet to the maximum extent and ensure the stable operation of the equipment. The front of the cabinet is designed with ventilation guides, and the air path is designed with front airflow and rear exhaust. The air outlet is located at the bottom of the back, and the wind direction is downward to avoid discomfort to users caused by being located at the back of the cabinet.

[0037] like Figure 3 As shown, an aviation plug-in panel is provided on the top of the expansion cabinet frame, and the external interface of the plug-in box is connected to the aviation plug-in panel.

[0038] like Fig.14 As shown, the cabinet body is formed by casting, and vibration isolators are arranged on the back and bottom; each unit adopts a plug-in box structure, and the side is connected to the cabinet through a slide rail or an equivalent structure, which can realize the front and back plug-in and pull-out of the chassis and the restriction of 4 degrees of freedom up, down, left and right; the rear of the plug-in box is connected with the cabinet locating pin seat with a positioning pin to realize auxiliary positioning with 4 degrees of freedom up, down, left and right; the screws on the front panel of the plug-in box are connected with the cabinet screw holes to realize 2 degrees of freedom positioning front and back. Through the above slide rails, positioning pins and panel screw structures, the plug-in box and the cabinet are fixedly connected, and can be plugged in and out front and back for easy maintenance. In particular, the inner and outer rails of the guide rails can be easily separated and reinstalled, so that the plug-in box can be quickly and completely separated and connected to the cabinet, which is convenient for unit-level spare parts replacement.

[0039] like Figure 4 As shown, the centralized cables are located in the space between the back panel of the cabinet and the rear of the unit; the cables of all unit plug-in boxes in the cabinet are routed to the rear of the cabinet through the cable tray. A standard cable duct is set on the left side of the rear wall of the cabinet. The cable duct allows the cable bundle to pass through with a cross-sectional area of ​​65cm2. Standard cable clamps, cable trays and cable trays are designed to ensure standardized and uniform routing. In order to ensure good grounding safety of each unit plug-in box, signal ground and chassis ground grounding busbars are designed on the side of the cabinet cable tray. The plug-in box end of the cable tray in the cabinet is fixed to the left side of the rear of the plug-in box, and the cabinet end is fixed to the cable tray of the cabinet. The insulation resistance between the cabinet signal ground and the chassis ground is ≥20MΩ, and the insulation resistance between the AC power input terminal and the chassis ground is ≥100MΩ.

[0040] like Fig.15 As shown, the cable rack includes a plug-in box fixed end, a cable rack, an angle limit plate and a cabinet fixed end, wherein the cabinet fixed end is fixed on the extended cabinet frame, the cabinet fixed end is connected to one end of the cable rack through a hinge, the cable rack includes a plurality of hinges, the hinges are provided with angle limit plates for limiting the opening and closing angles of the hinges for folding the cable rack, the other end of the cable rack is connected to the plug-in box fixed end, and the plug-in box fixed end is connected to the internal circuit in the form of a plug-in box.

[0041] Compared with the previous similar equipment, this equipment has been redesigned in the cable rack. The original cable rack has no cable protection backup. When the cabinet plug-in box is pushed into the cabinet, it is easy to cause cable compression. This cabinet is designed with a single-degree-of-freedom multi-axis cable rack component. Fig.16 As shown, part 1 is connected to the cabinet body, and part 2 is connected to the plug-in box. When the plug-in box slides toward the outside of the cabinet under the action of the slide rail installed on the side wall, the angle between the two cable racks increases, and the cables bundled thereon move forward with the cable rack and the plug-in box synchronously, avoiding the entanglement of the cables with other equipment in the cabinet, providing effective protection for the cables and welding points. The reliability of the equipment cables is greatly improved.

[0042] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manner derived by those skilled in the art based on the technical solution of the present invention also falls within the scope of protection of the present invention.
