[0041] The present application embodiment provides a cable-free airborne chassis. Figures 1 to 3 The cable-free airborne chassis comprises a housing 1, a motherboard 2, a switching board 3 and at least two functional modules 5; wherein:

[0042] The vertical side wall of the box body 1 is provided with an avoidance through hole 101 .

[0043] The motherboard 2 is laid flat on the bottom of the inner cavity of the box body 1 , and at least two first connection ends 21 electrically connected to each other are arranged at intervals on the upper surface of the motherboard 2 .

[0044] The adapter board 3 is connected to the motherboard 2 through the flexible circuit board 4. The adapter board 3 and the motherboard 2 are perpendicular to each other. The adapter board 3 is provided with a plurality of aviation plugs 31. The aviation plugs 31 are inserted into the avoidance through holes 101 and extend to the outside of the box body 1. The aviation plugs 31 are electrically connected to at least two first connection ends 21.

[0045] At least two functional modules 5 are vertically inserted into the inner cavity of the box body 1 . The functional modules 5 have second connection ends (not shown in the figure), and the second connection ends are connected to the first connection ends 21 in a one-to-one correspondence.

[0046] In this embodiment, the box body 1 can be of an integrated type or a spliced ​​type, and the number of avoidance through holes 101 can be set according to the number of aviation plugs 31. The motherboard 2 can adopt a rigid printed circuit board, and the first connection end 21 can be a socket fixed to the motherboard 2 by soldering or the like, and each first connection end 21 is electrically connected through the printed circuit on the motherboard 2. The adapter board 3 can adopt a rigid printed circuit board, and the aviation plug 31 has excellent characteristics such as high temperature resistance, wear resistance, corrosion resistance, safety and reliability. The aviation plug 31 can be fixed to the adapter board 3 by soldering or the like, and the number of aviation plugs 31 can be set according to actual needs. The aviation plug 31 can be electrically connected to each first connection end 21 through the printed circuit on the adapter board 3, the flexible circuit board 4, and the printed circuit on the motherboard 2 in turn. Figure 2 As shown, one end of the flexible circuit board 4 is led out from one side of the motherboard 2, and the other end of the flexible circuit board 4 is connected to one side of the adapter board 3. The motherboard 2, the flexible circuit board 4 and the adapter board 3 are designed in an integrated manner; since the flexible circuit board 4 has the characteristic of being bendable and deformable, the adapter board 3 and the motherboard 2 can be made perpendicular to each other by bending the flexible circuit board 4, so that the motherboard 2 can be horizontally laid on the bottom of the inner cavity of the box body 1, and the vertically arranged adapter board 3 is installed on the vertical side wall of the box body 1, and at the same time, the aviation plug 31 on the adapter board 3 passes through the avoidance through hole 101, so that the plug-in part of the aviation plug 31 extends to the outside of the box body 1, so as to facilitate the connection end of the external device to be plugged into the aviation plug 31, so as to realize the electrical connection between the external device and the aviation plug 31.

[0047] The width and depth of the functional module 5 can be set to 3U, 6U, 8U or 9U, and the height of the functional module 5 can be set to 4HP or 5HP; wherein 1U = 4.445 cm, 1HP = 5.08 mm.

When the functional modules 5 are placed in the inner cavity of the box body 1 in sequence, each functional module 5 is plugged into the corresponding first connection end 21 on the motherboard 2 through its own second connection end. In this way, the motherboard 2 can interconnect the signals and power supplies of each functional module 5, so that each functional module 5 can be powered and communicated with each other, and each functional module 5 can also be powered and communicated with the outside through the aviation plug 31 on the adapter board 3 at the same time, thereby realizing signal transmission inside the airborne chassis and signal transmission between the airborne chassis and external equipment without the help of cables.

[0048] It can be seen that the cable-free airborne chassis provided in the present embodiment adopts a cable-free design. No cables are arranged between the functional modules 5, and no cables are arranged between the functional modules 5 and the aviation plug 31 for connecting external devices. Moreover, the functional modules 5 can communicate with each other through the motherboard 2, and multiple functional modules 5 can also simultaneously communicate with the outside through the aviation plug 31 on the adapter board 3. While ensuring the communication function, there is no cable inside the entire chassis, thereby keeping the inside of the chassis clean and tidy, saving the wiring space occupied by the cables, making the chassis smaller and lighter, and reducing the assembly time of the chassis, improving the assembly efficiency, reducing the frequency of assembly operation errors of the chassis, and improving the assembly quality. In addition, the cable-free airborne chassis also realizes the relative vertical placement between the motherboard 2 and the adapter board 3 through the flexible circuit board 4, so that the internal space layout of the chassis is more reasonable and the structure is more compact.

[0051] Optionally, refer to Figures 1 to 3 The upper surface of the motherboard 2 is provided with a guide pin 22, and the functional module 5 is provided with a guide sleeve (not shown in the figure), and the guide pin 22 is inserted into and fitted in the guide sleeve.

[0052] Specifically, through the cooperation between the guide pin 22 and the guide sleeve, the functional module 5 can be conveniently positioned, so that the functional module 5 can be quickly plugged into a preset position on the motherboard 2 to ensure accurate docking between the second connection end and the first connection end 21.

[0053] Optionally, refer to Figure 3 The lower surface of the motherboard 2 is provided with reinforcing ribs 23, and the number of the reinforcing ribs 23 can be set according to actual needs; the reinforcing ribs 23 can improve the structural strength of the motherboard 2 and prevent the motherboard 2 from bending and deformation.

[0054] Optionally, refer to Figures 1 to 3 The box body 1 includes a bottom plate 11, a front panel 12, a rear panel 13, a left side panel 14 and a right side panel 15; the front panel 12, the rear panel 13, the left side panel 14 and the right side panel 15 are respectively detachably connected to the four sides of the bottom plate 11, and the bottom plate 11, the front panel 12, the rear panel 13, the left side panel 14 and the right side panel 15 enclose an inner cavity of the box body 1; an avoidance through hole 101 is opened on the front panel 12; at least two functional modules 5 are arranged at intervals along a first direction, and the first direction is perpendicular to the front panel 12.

[0055] like Figure 1 As shown, when the box 1 adopts a structure in which multiple panels are spliced ​​together, it can be easier to disassemble and assemble the box 1 itself and the various devices inside the box 1; among which, the bottom plate 11, the front panel 12, the rear panel 13, the left side panel 14, and the right side panel 15 can be connected and fixed by means of threaded fasteners or snap connections.

[0056] Optionally, refer to Figure 1 The box body 1 includes an upper cover plate 16 ; the upper cover plate 16 is detachably covered on the upper edges of the front panel 12 , the rear panel 13 , the left side panel 14 , and the right side panel 15 to close the inner cavity of the box body 1 .

[0057] Specifically, by providing the upper cover plate 16, the chassis can be covered to form a closed space, thereby providing protection for the components inside the chassis and ensuring the working stability of the corresponding components.

[0058] Optionally, refer to Figure 1 The bottom plate 11 is provided with a hanging ring 111.

[0059] Optionally, refer to Figure 1 The upper cover plate 16 is provided with a handle 161 .

[0060] By providing the lifting ring 111 and the handle 161, the cable-free airborne chassis can be more conveniently transported and hoisted.

[0061] Optionally, refer to Figure 1The cable-free airborne chassis includes a heat dissipation fan 6, a first air outlet (not shown in the figure) is opened on the rear panel 13, a second air outlet is opened on the front panel 12, and the heat dissipation fan 6 is arranged at the first air outlet, and the heat dissipation fan 6 is opposite to the functional module 5 closest to the rear panel 13.

[0062] Optionally, refer to Figures 1 to 3 The left side plate 14 and / or the right side plate 15 are provided with heat dissipation holes (not shown in the figure).

[0063] Specifically, the functional module 5 closest to the front panel 12 has a certain spacing distance from the front panel 12, the functional module 5 closest to the rear panel 13 has a certain spacing distance from the rear panel 13, and there is a certain spacing distance between the vertical sides of the multiple functional modules 5 and the left panel 14 and the right panel 15, so that an air duct can be formed around the multiple functional modules 5. When the heat dissipation fan 6 sends air into the inner cavity of the box body 1 through the first air outlet, the air blown by the heat dissipation fan 6 can flow through each functional module 5 along the above-mentioned air duct and finally flow out from the second air outlet; and when the heat dissipation fan 6 draws air from the inner cavity of the box body 1 through the first air outlet, the air flow enters from the second air outlet and flows through each functional module 5, and finally is drawn out by the heat dissipation fan 6 through the first air outlet; based on the above-mentioned settings, the heat dissipation and cooling effect can be achieved, and the heat generated by the functional module 5 can also be discharged to the outside of the box body 1 through the heat dissipation through hole, thereby avoiding the excessively high temperature inside the box body 1 and causing adverse effects on the normal operation of components such as the functional module 5.

[0064] Optionally, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The cable-free airborne chassis includes at least two adjustment rods 7, which are arranged at intervals along a first direction, and the adjustment rods 7 are rotatably connected to the left side plate 14 and / or the right side plate 15 around a vertical axis;

[0065] Each adjusting rod 7 is provided with at least two first air guide fins 8, and the at least two first air guide fins 8 are arranged at intervals along the extending direction of the adjusting rod 7, and the first air guide fins 8 are used to guide the air blown out or extracted from the heat dissipation fan 6 to between two adjacent functional modules 5;

[0066] The cable-free airborne chassis includes a second air guide fin 9; the first air guide fin 8 is provided with a flow hole 81, and the second air guide fin 9 is hinged at the flow hole 81 around a vertical axis, and the second air guide fin 9 is used to guide the wind passing through the flow hole 81 to between two adjacent functional modules 5.

[0067] like Figures 4 to 7As shown, a first air duct 200 is formed inside the left side plate 14 on the left side of the plurality of functional modules 5, and a second air duct 300 is formed inside the right side plate 15 on the right side of the plurality of functional modules 5. When the heat dissipation fan 6 delivers or extracts air, the airflow will be diverted to the left or right side and enter the first air duct 200 and the second air duct 300; since the airflow after entering the first air duct 200 and the second air duct 300 mainly flows along the extension direction of the air duct, less airflow is dispersed laterally into the gap between two adjacent functional modules 5 during the flow process, that is, the air volume in the area between each functional module 5 is less, so it is difficult to take away the heat generated in the area between each functional module 5 in time, resulting in a large difference in the heat dissipation and cooling effect at each position in the inner cavity of the box body 1.

[0068] Based on the above problems, in this embodiment, an adjustment rod 7 with a first air guide fin 8 is respectively arranged inside the left side panel 14 and inside the right side panel 15. The first air guide fin 8 is inclined at a certain angle relative to the rear panel 13, and the second air guide fin 9 is also inclined at a certain angle relative to the first air guide fin 8.

[0071] Reference Figure 6 When the heat dissipation fan 6 draws air, the first air guide fin 8 in the second air duct 300 can be flush with the gap between each group of two adjacent functional modules 5, and the first air guide fin 8 in the first air duct 200 can be flush with each functional module 5; the first air guide fin 8 and the second air guide fin 9 are both inclined toward the side of the rear panel 13, and the angle between the second air guide fin 9 and the front panel 12 is greater than the angle between the first air guide fin 8 and the front panel 12; the second air outlet is set on the second air duct 300; a baffle can be set between the heat dissipation fan 6 and the second air duct 300. After the heat dissipation fan 6 starts to draw air, a part of the airflow entering the second air duct 300 from the second air outlet will be guided by the first air guide fin 8 along the inclined direction during the backward flow, and then this part of the airflow can enter the first group of two adjacent functional modules 5 laterally; and another part of the airflow in the second air duct 300 will pass through the flow hole 81 and be guided by the second air guide fin 9 along the inclined direction, and then this part of the airflow can enter the second group of two adjacent functional modules 5 laterally and reach the next group of first air guide fins 8, and continue the above-mentioned air guiding process; and the airflow entering between the two adjacent functional modules 5 will flow to the left into the first air duct 200, and the airflow entering the first air duct 200 will pass through the flow hole 81 of the first air guide fin 8 on the left and flow backward along the first air duct 200 until it is discharged outward from the first air outlet through the heat dissipation fan 6.

[0072] Reference Figure 7 When the heat dissipation fan 6 draws air, the first air guide fin 8 in the first air duct 200 can be flush with the gap between each group of two adjacent functional modules 5, and the first air guide fin 8 in the second air duct 300 can be flush with each functional module 5; the first air guide fin 8 and the second air guide fin 9 are both inclined toward the side of the rear panel 13, and the angle between the second air guide fin 9 and the front panel 12 is greater than the angle between the first air guide fin 8 and the front panel 12; the second air outlet is set on the first air duct 200; a baffle can be set between the heat dissipation fan 6 and the first air duct 200.

[0073] The number of the adjusting rods 7 can be set according to the number of the functional modules 5 to ensure that the airflow in the air duct can enter between each group of two adjacent functional modules 5 under the guidance of the first air guide fins 8 and the second air guide fins 9 on different adjusting rods 7. The operator can also rotate the adjusting rod 7 and the second air guide fins 9 according to actual needs to flexibly change the inclination angles of the first air guide fins 8 and the second air guide fins 9 to ensure that the airflow can be accurately guided to the target position by the first air guide fins 8 and the second air guide fins 9 along the preset angle.

[0075] Optionally, refer to Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The first air guide fins 8 on each group of two adjacent adjustment rods 7 are arranged in a vertical direction with gaps between them on the first projection plane, and the first projection plane is parallel to the rear panel 13 .

[0076] like Figures 4 to 8As shown, taking the first air duct 200 as an example, the first air guide fins 8 on each group of two adjacent adjusting rods 7 are arranged with gaps in the vertical direction. When the airflow flowing forward in the first air duct 200 reaches the first adjusting rod 7, part of the airflow is laterally guided by the first air guide fins 8 on the first adjusting rod 7 to between the two adjacent functional modules 5 of the first group, and the other part of the airflow is not blocked by the first air guide fins 8 on the first adjusting rod 7 and continues to flow forward; when the part of the airflow that continues to flow forward reaches the second adjusting rod 7, part of the airflow is laterally guided by the first air guide fins 8 on the second adjusting rod 7 to between the two adjacent functional modules 5 of the second group, and the other part of the airflow is not blocked by the first air guide fins 8 on the second adjusting rod 7 and continues to flow forward; and so on, the reasonable distribution of air volume at each position on the first air duct 200 can be achieved, further improving the uniformity of air volume distribution and the overall heat dissipation and cooling effect.

[0077] Based on the above-mentioned interlaced arrangement of the first air guide fins 8 , the flow of the air in the second air duct 300 is similar, which will not be described here.

[0078] In a preferred embodiment, a temperature sensing device is provided in the area between each group of two adjacent functional modules 5, a first driving device is provided on the adjusting rod 7, the first driving device is used to drive the adjusting rod 7 to rotate, and a second driving device is provided on the second air guide fin 9, the second driving device is used to drive the second air guide fin 9 to rotate relative to the first air guide fin 8; the temperature sensing device is electrically connected to the first driving device and the second driving device through the adjusting module.

[0079] The adjustment module can specifically select an MCU microcontroller, and the adjustment module stores the correspondence between the temperature value and the inclination angle of the first air guide fin 8 and the inclination angle of the second air guide fin 9; when the temperature sensor device sends the acquired real-time temperature value to the adjustment module, the adjustment module can send corresponding adjustment signals to the first drive device and the second drive device according to the above correspondence, so as to trigger the first drive device and the second drive device to drive the first air guide fin 8 and the second air guide fin 9 to rotate to a preset angle, thereby realizing automatic adjustment of the air guide condition without manual intervention, thereby realizing autonomous control of the air volume at various locations.
