[0027] Embodiment: A multifunctional server chassis, such as Figures 1-4As shown, it includes: a chassis shell 11, in which the core components inside the server are installed; a side panel 12 assembled and fixedly installed on the side of the chassis shell 11, and the internal space of the chassis shell 11 can be opened by removing the side panel 12; a mounting panel 13 fixedly installed on the front and rear sides of the chassis shell 11, and the mounting panel 13 is assembled and fixed with the core components. The mounting panel 13 will serve as a transfer hub between the core components and the outside world, and undertakes key functions such as physical fixation, electrical connection, signal transmission and interface expansion; a mounting shaft 14 fixedly installed on the chassis shell 11, and there are two chassis shells 11. The two chassis shells 11 are rotatably installed through the mounting shaft 14. The mounting shaft 14 is set on the chassis shell 11 on the left side. By rotating and folding the chassis shell 11, the adaptive adjustment of the size of the server chassis is achieved. In particular, when the two chassis shells 11 are unfolded, the side that the two are in contact with each other at this time is defined as the B side, and when the two chassis shells 11 are folded, the side that the two are in contact with each other at this time is defined as the A side. See for details. Figure 3 and Figure 4 .

[0028] like Figure 2 、 Figure 5 and Figure 6 As shown, it also includes: a locking component provided between the two chassis shells 11, the locking component is used to lock the chassis shell 11 to ensure the stability of the use of the server chassis; a control component provided in the chassis shell 11, the control component is connected to the locking component, and is used to drive the control locking component to operate; Figure 2 、 Figure 7 and Figure 8 As shown, it also includes: an unlocking component arranged in the left chassis shell 11, and the unlocking component is connected to the components of the locking component to control the unlocking state of the chassis shell 11.

[0029] The locking assembly includes: two rotating rods 21 rotatably mounted on the A and B surfaces of the right chassis shell 11, and a section of thread is provided on the rotating rod 21; two guide groove blocks 22 slidably mounted on the A and B surfaces of the right chassis shell 11, and the two guide groove blocks 22 realize transmission control by forming a thread pair with the threads at the ends of the two rotating rods 21, and an oblique guide groove is provided on the guide groove block 22; two plug-in blocks 23 slidably mounted on the A and B surfaces of the right chassis shell 11, and through the guide groove cooperation, the plug-in blocks 23 on the same side of the A and B surfaces form a sliding contact pair with the guide groove blocks 22 to realize transmission control; Two plug rods 24 are dynamically mounted on the A and B surfaces of the left chassis shell 11. The plug block 23 is provided with a hole for the plug rod 24 to pass through, and an inclined surface for contacting and cooperating with the plug rod 24. The end of the plug rod 24 is provided with a spherical portion for contacting and cooperating with the plug block 23, so that when the plug rod 24 is displaced, it can smoothly contact with the plug block 23 and realize plug-in cooperation to form a lock. When the two chassis shells 11 are unfolded, the plug block 23 on the B surface cooperates with the plug rod 24. When the two chassis shells 11 are folded, the plug block 23 on the A surface cooperates with the plug rod 24; a reset spring 25 is provided on the plug rod 24 for resetting the plug rod 24.

[0030] The control assembly includes: a first transmission rod 26 rotatably mounted in the right chassis shell 11; a transmission gear 27 fixedly mounted on the first transmission rod 26 and on the mounting shaft 14, the two transmission gears 27 being meshed; a first bevel gear 28 fixedly mounted on the first transmission rod 26 and on the two rotating rods 21 respectively, the first bevel gears 28 on the two rotating rods 21 being meshed with the first bevel gear 28 on the first transmission rod 26, so that the two rotating rods 21 rotate synchronously. Specifically, the transmission relationship between the two plug-in blocks 23 involves the selection of direction variables, including the direction of the guide groove on the guide groove block 22 and the direction of the thread on the rotating rod 21. A two-choice direction reverse configuration scheme will be adopted. In this embodiment, a design scheme of reverse setting of the threads on the rotating rod 21 is adopted so that when the two rotating rods 21 rotate synchronously, one of the plug-in blocks 23 will be controlled to move toward the inside of the chassis shell 11, and the other plug-in block 23 will move toward the outside of the chassis shell 11.

[0031] The unlocking assembly includes: a control rod 31 rotatably mounted on the A and B surfaces of the left chassis shell 11, and the control rod 31 is provided with a thread; a limit plate 32 slidably mounted on the A and B surfaces of the left chassis shell 11, and the two limit plates 32 correspond to the threads of the two control rods 31 to form a thread pair to realize transmission control, and the two insertion rods 24 are slidably mounted corresponding to the two limit plates 32, and the return spring 25 on the insertion rod 24 will be fixed between the insertion rod 24 and the limit plate 32; a handle 33 fixedly mounted on the end of the control rod 31, and the handle 33 is arranged on the outside of the chassis shell 11; a return torsion spring 34 fixedly mounted between the control rod 31 and the chassis shell 11 for resetting the control rod 31.

[0032] There are two groups of locking components, control components and unlocking components to improve the stability of the server chassis. In particular, the two groups of unlocking components will be equipped with four control rods 31. The two control rods 31 located on the A side are fixed as one body, and the two control rods 31 located on the B side are fixed as one body, so that the limit plates 32 on the same side of the A side and the B side in the two groups of unlocking components can be uniformly controlled.

[0033] When operating this server chassis, rotating the left chassis shell 11 so that it overlaps with the A side of the right chassis shell 11 will fold the server chassis, shortening its overall length. Conversely, flipping the left chassis shell 11 so that it overlaps with the B side of the right chassis shell 11 will unfold the server chassis, reducing its overall height. Therefore, this server chassis can be flexibly adjusted to meet the actual installation space requirements.

[0034] When the length of the installation space is less than the original total length of the server chassis, the handle 33 at the B-side position is used to rotate the control rod 31, and the reset torsion spring 34 is twisted and deformed, and the movement of the control limit plate 32 is controlled to drive the insertion rod 24 to move, and the insertion rod 24 at the B-side position is controlled to be out of the plug-in matching state with the insertion block 23; then, the left chassis shell 11 can be rotated to fold, shortening the total length of the server chassis. In this process, the installation shaft 14 will generate relative rotational motion with the right chassis shell 11, and the first transmission rod 26 can be driven to rotate by the transmission gear 27, and the two rotating rods 21 can be driven to rotate synchronously by the first bevel gear 28. The rotating rod 21 controls the movement of the guide groove block 22 through the thread on it, and the guide groove block 22 controls the movement of the plug block 23 through the upper inclined guide groove. At this time, the plug block 23 on the A side will move toward the outside of the right chassis shell 11 and be inserted into the left chassis shell 11 located above, and the plug block 23 on the B side will move toward the inside of the right chassis shell 11. When the plug block 23 is inserted into the left chassis shell 11 and contacts the insertion rod 24 on the A side, the inclined surface of the plug block 23 squeezes the insertion rod 24 on the A side, controls the insertion rod 24 to move relative to the limit plate 32 and compresses the return spring 25. As the relative displacement continues, the insertion rod 24 will eventually align with the socket on the plug block 23. The return spring 25 recovers its deformation and pushes the insertion rod 24 into the socket, so that the plug block 23 and the insertion rod 24 form an inserted fit, locking the two chassis shells 11.

[0035] On the contrary, if the height of the installation space is insufficient, rotate the handle 33 on the A side to control the insertion rod 24 on the A side and the insertion block 23 to disengage the inserted mating state, and then rotate the left chassis shell 11 in the opposite direction to make the B sides of the two chassis shells 11 overlap. At this time, the reversely rotating installation shaft 14 will control the A side insertion block 23 to retract inward, releasing the A side lock. At the same time, the B side insertion block 23 will move outward and embed into the B side insertion rod 24 of the left chassis shell 11 to achieve a new locking state.

[0036] Therefore, the server chassis adopts a foldable chassis shell 11 design, which can flexibly adjust the overall size according to environmental requirements, thereby improving the deployment adaptability and space utilization of the server chassis. During adjustment, the built-in locking assembly operates synchronously to lock the chassis, ensuring the structural stability of the server chassis during use. The control assembly uses the relative position change of the server chassis when it is unfolded and folded to realize the control and locking assembly operation, and the unlocking assembly realizes the rapid unlocking of the locking assembly. By using the control assembly and the unlocking assembly, the operation process will be simplified and the convenience of equipment adjustment will be greatly improved.

[0037] like Figure 3 and Figure 11 As shown, the chassis shell 11 is composed of a first branch 1101 and a second branch 1102, and the first branch 1101 and the second branch 1102 are slidably installed between each other. The first branch 1101 and the second branch 1102 can move relative to each other, thereby adjusting the volume inside the chassis shell 11. The first branches 1101 of the two chassis shells 11 are rotatably installed through the installation shaft 14, and the side panel 12 is set on the second branch 1102 in the chassis shell 11; the rotating rod 21 on the A side is composed of a first support rod 2101 and a second support rod 2102, and the first support rod 2101 and the second support rod 2102 are slidably installed so that the rotating rod 21 can maintain synchronous telescopic movement with the right chassis shell 11 where it is located.

[0038] like Figure 2 、 Figure 9 and Figure 10 As shown, it also includes: an adjustment component arranged in each chassis shell 11, and the adjustment component is used to independently adjust the volume of each chassis shell 11, so that the server chassis can be flexibly expanded or reduced in capacity according to actual usage needs, thereby improving the applicability of the server chassis to better adapt to different scenarios and application requirements.

[0039] The adjusting assembly includes: a threaded rod 41 rotatably installed in the first branch 1101, the threaded rod 41 is respectively arranged on the upper and lower sides of the first branch 1101, and the ends of the threaded rod 41 are located outside the first branch 1101. In this embodiment, the threads at both ends of the threaded rod 41 are symmetrically arranged; a moving block 42 slidably installed in the first branch 1101, the moving block 42 and the threaded rod 41 form a thread pair to realize transmission control, and the moving block 42 is provided with four blocks on the upper and lower sides, a total of eight blocks; a connecting arm 43 rotatably installed between the moving block 42 and the second branch 1102; a second transmission rod 44 rotatably installed in the first branch 1101; a second bevel gear 45 fixedly installed on the upper and lower ends of the second transmission rod 44 and on the upper and lower threaded rods 41, wherein the second bevel gear 45 on the upper threaded rod 41 is meshed with the second bevel gear 45 at the upper end of the second transmission rod 44, and the second bevel gear 45 on the lower threaded rod 41 is meshed with the second bevel gear 45 at the lower end of the second transmission rod 44.

[0040] When the upper threaded rod 41 is rotated, the second transmission rod 44 and the second bevel gear 45 realize the synchronous rotation of the upper and lower threaded rods 41. This rotation will drive the moving block 42 to produce displacement, thereby adjusting the extension of the connecting arm 43 in the length direction of the chassis shell 11. By changing the relative position of the second branch 1102 and the first branch 1101, the internal volume of the chassis shell 11 can be precisely controlled.

[0041] like Figure 2 and Figure 11 As shown, it also includes: a mounting rail 51 fixedly installed in the chassis shell 11, the mounting rail 51 is fixed to the first branch 1101; a mounting frame 52 slidably installed on the mounting rail 51, the mounting frame 52 can be extended and retracted, and the two ends are respectively fixedly connected to the first branch 1101 and the second branch 1102, ensuring that the mounting frame 52 can maintain synchronous extension and retraction movement with the chassis shell 11, and the core components are fixedly installed on the mounting frame 52.

[0042] When it is necessary to inspect and repair the core components, first remove the side panel 12 and release the connection between the core components and the installation panel 13. At this time, the core components can be taken out from the chassis shell 11 for inspection, thereby improving the convenience of inspection and repair of the server chassis. When the chassis shell 11 is controlled to expand and contract to adjust the internal volume, the mounting frame 52 can be simultaneously expanded to accommodate larger core components without manual adjustment, which is convenient to use.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
