Description

Technical Field

[0001] This invention relates to the field of computer technology, and more specifically, to a tool-free disassembly and assembly module, a module fixing component, and a server chassis. Background Technology

[0002] In existing technologies, server circuit boards are generally fixed in two ways: the first is by directly tightening screws, and the second is by using a combination of T-shaped screws and auger holes with screws or by hand-turning screws. Both screw fixing and T-shaped screw and auger hole fixing with screws require tools such as screwdrivers to disassemble and install the circuit boards. The T-shaped screw and auger hole fixing with hand-turning screws is usually tightened with an electric screwdriver during production. However, when disassembling, some people with weak fingers may not be able to turn the screws. Summary of the Invention

The third telescopic knob has a third telescopic rod, and the axial end of the third telescopic rod has a fourth inclined surface for cooperating with the third inclined surface. During the sliding of the module fixing assembly along a second preset direction, the third telescopic rod is pushed to move in a direction away from the second protrusion structure by the cooperation of the third inclined surface and the fourth inclined surface until the module fixing assembly is installed in place, at which point the third telescopic rod falls into the second limiting hole under its own weight.

[0016] By having a first guide sliding structure and a first protrusion structure on the bottom surface of at least the bearing groove of the bearing pallet, and a second guide sliding structure and a first telescopic knob on the component to be supported, the first guide sliding structure and the second guide sliding structure slide together. Combined with the cooperation of the first protrusion structure and the first telescopic knob, tool-free quick installation and disassembly of the bearing pallet and the component to be supported are achieved. This ensures the ease of installation and disassembly of the bearing pallet and the component to be supported, while also saving manpower.

[0017] Furthermore, the module fixing assembly includes a module fixing frame and a tool-less assembly / disassembly module, wherein the module fixing frame has at least one first pull-out hole; the tool-less assembly / disassembly module is pull-outably disposed at the first pull-out hole, and the tool-less assembly / disassembly module is the aforementioned tool-less assembly / disassembly module. This ensures convenient assembly between the module fixing frame and the tool-less assembly / disassembly module.

[0018] Furthermore, the server chassis includes a chassis body and a module fixing assembly. The chassis body has a receiving groove and a component fixing frame. The component fixing frame has a second pull-out hole that communicates with the receiving groove.

The third telescopic knob has a third telescopic rod, and the axial end of the third telescopic rod has a fourth inclined surface for cooperating with the third inclined surface. During the sliding of the module fixing assembly along a second preset direction, the third telescopic rod is pushed to move in a direction away from the second protrusion structure through the cooperation of the third inclined surface and the fourth inclined surface until the module fixing assembly is installed in place. At least under its own weight, the third telescopic rod falls into the second limiting hole.

[0019] By providing a second protruding structure at at least one position on the wall of the receiving slot and the wall of the second pull-out hole, and by providing a third telescopic knob on the module fixing component, tool-free quick installation and disassembly are achieved between the chassis body and the module fixing component. This ensures the ease of installation and disassembly between the chassis body and the module fixing component, while also saving manpower. Attached Figure Description

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0040] To address the issue that existing server components, such as circuit boards, typically require external tools for installation and disassembly, this invention provides a tool-free disassembly / reassembly module, module fixing components, and server chassis.

[0041] like Figures 1 to 12 As shown, the tool-free assembly / disassembly module includes a support tray 10 and a component to be supported 20. The support tray 10 has a support groove 11, and at least the bottom surface of the groove 11 has a first guide sliding structure 12 and a first protrusion structure 13. The component to be supported 20 has a second guide sliding structure 21 and a first telescopic knob 22, with the second guide sliding structure 21 slidingly engaging with the first guide sliding structure 12. The end surface of the first protrusion structure 13 has a first limiting hole 131, and at least a portion of the outer peripheral surface of the first protrusion structure 13 is... The first inclined surface and the first telescopic knob 22 have a first telescopic rod 221, and the axial end of the first telescopic rod 221 has a second inclined surface 2211 for cooperating with the first inclined surface. During the process of the carrying tray 10 sliding along the first preset direction, the first telescopic rod 221 is pushed to move in the direction away from the first protruding structure 13 by the cooperation of the first inclined surface and the second inclined surface 2211 until the carrying tray 10 is installed in place, and the first telescopic rod 221 falls into the first limiting hole 131 at least under its own weight.

[0042] By having a first guide sliding structure 12 and a first protrusion structure 13 on the bottom surface of at least the bearing groove 11 of the bearing tray 10, and by providing a second guide sliding structure 21 and a first telescopic knob 22 on the component to be supported 20, the first guide sliding structure 12 and the second guide sliding structure 21 are slidably engaged, and the first protrusion structure 13 and the first telescopic knob 22 are combined to achieve tool-free quick installation and disassembly between the bearing tray 10 and the component to be supported 20, ensuring the convenience of installation and disassembly between the bearing tray 10 and the component to be supported 20, while also saving manpower.

[0043] In one embodiment of this application (not shown), the first telescopic knob 22 also has a spring that abuts against the first telescopic rod 221 to provide an elastic force for the first telescopic rod 221 to move toward the first limiting hole 131, so that the first telescopic rod 221 can quickly fall into the first limiting hole 131 under the push of the elastic force of the spring and its own gravity.

[0044] like Figure 3 As shown, there are multiple first guide sliding structures 12, which are distributed at different positions on the bottom surface of the bearing groove 11; there are multiple second guide sliding structures 21, which correspond one-to-one with the multiple first guide sliding structures 12; and / or, there are multiple first protrusion structures 13, which are distributed at different positions on the bottom surface of the bearing groove 11; there are multiple first telescopic knobs 22, which correspond one-to-one with the multiple first protrusion structures 13.

[0045] like Figures 7 to 9As shown, the first telescopic knob 22 includes a housing 222, a first operating knob 223, and a first telescopic rod 221. The housing 222 is connected to the component to be supported 20 and has a first clearance through hole. The first operating knob 223 is screwably connected to the housing 222 and has a second clearance through hole and a first limiting spiral groove 2231. The second clearance through hole is concentric with and communicates with the first clearance through hole, and the second clearance through hole communicates with the first limiting spiral groove 2231. The bottom surface of the first limiting spiral groove 2231 extends spirally in a direction away from the plane where the axial end of the second clearance through hole is located. The first limiting spiral grooves 2231 are arranged in pairs. The first end of the first telescopic rod 221 passes through the first clearance through hole and the second clearance through hole in sequence and extends into the first limiting spiral groove 2231. At point 1, a radial through hole is provided on the first telescopic rod 221; the first telescopic knob 22 also includes a first pin 224, which passes through the radial through hole, and the axial ends of the first pin 224 are respectively used to cooperate with the bottom surfaces of the two first limiting spiral grooves 2231; when the first operating knob 223 is rotated in the first direction, the first pin 224 cooperates with the bottom surfaces of the two first limiting spiral grooves 2231 to drive one end of the first telescopic rod 221 with the second inclined surface 2211 back into the first clearance through hole; when the first operating knob 223 is rotated in the second direction opposite to the first direction, the first pin 224 cooperates with the bottom surfaces of the two first limiting spiral grooves 2231 to drive one end of the first telescopic rod 221 with the second inclined surface 2211 to extend out of the first clearance through hole. In this way, by setting the first telescopic knob 22 into a structure including a housing 222, a first operating knob 223 and a first telescopic rod 221, the limiting reliability of the first telescopic knob 22 is ensured.

[0046] Preferably, the housing 222 is welded to the component 20 to be supported.

[0047] Preferably, at least one of the lowest and highest positions of the first limiting spiral groove 2231 has a supporting plane to provide support for the first pin 224.

[0048] like Figure 3As shown, a clearance notch 14 is provided on the side wall of the support tray 10; the tool-free assembly / disassembly module 2 also includes a handle structure 30, which is rotatably mounted on the support tray 10. The handle structure 30 has a locking end and a limiting end. The locking end is used to engage with the support tray 10. When the locking end is locked with the support tray 10, the limiting end is located outside the clearance notch 14 and protrudes from the side wall of the support tray 10 to engage with the snap-fit ​​hole 101 on the module fixing frame 1 of the server chassis. When the locking end is unlocked from the support tray 10, the limiting end is turned into the clearance notch 14 by rotating the handle structure 30 to avoid sliding engagement between the tool-free assembly / disassembly module 2 and the module fixing frame 1. This ensures convenient assembly / disassembly of the tool-free assembly / disassembly module 2 and the module fixing frame 1.

[0049] like Figure 10 and Figure 11 As shown, a locking hole 15 is provided on the side wall of the support tray 10, and the locking hole 15 and the clearance notch 14 are located on different side walls of the support tray 10; the handle structure 30 includes a handle body 31, a second telescopic knob 32 and a limiting protrusion 33, wherein the handle body 31 is rotatably mounted on the support tray 10, and the first end of the handle body 31 has a third clearance through hole 311; the second telescopic knob 32 is provided at the first end of the handle body 31 to form a locking end, and the second telescopic knob 32 has a second telescopic rod 321, the second telescopic rod 321 has an extended state that passes through the third clearance through hole 311 and extends into the locking hole 15 to lock and engage with the locking hole 15, and the second telescopic rod 321 has a retracted state that is at least withdrawn from the locking hole 15; the limiting protrusion 33 is provided at the end of the second end of the handle body 31 and extends in a direction away from the handle body 31 to form a limiting end. This ensures the reliable fit between the square mushroom head of the second telescopic rod 321 of the second telescopic knob 32 and the limiting boss 17 of the locking hole 15.

[0050] like Figure 3As shown, an assembly post 16 is also provided on the bottom surface of the bearing groove 11, and the assembly post 16 has an axial through hole; the tool-free disassembly module 2 also includes a spring structure 40 and a second pin 50, wherein the spring structure 40 is sleeved on the outer periphery of the assembly post 16, and one end of the spring structure 40 is connected to the groove wall of the bearing groove 11, and the other end of the spring structure 40 is connected to the handle structure 30, so as to provide the handle structure 30 with an elastic force to rotate away from the locking hole 15 of the bearing tray 10; the second pin 50 includes a connected disc-shaped head, a first shaft section and a second shaft section, and the first diameter D1 of the disc-shaped head, the second diameter D2 of the first shaft section and the third diameter D3 of the second shaft section satisfy: D1 > D3 > D3, so that a step is formed at the connection between the first shaft section and the second shaft section; the second pin 50 passes through the axial through hole and the second shaft section extends into the assembly hole 34 on the handle structure 30. In this way, the rotation reliability of the handle structure 30 is ensured.

[0051] Preferably, the first guide sliding structure 12 is an I-shaped nail protruding from the bottom surface of the bearing groove 11; the second guide sliding structure 21 is a gourd-shaped hole opened on the component to be supported 20.

[0052] It should be noted that, in this application, the following describes the assembly of the tool-free disassembly module 2 in detail. First, the first guide sliding structure 12 and the assembly post 16 are riveted to the support tray 10. Then, the second telescopic knob 32 is riveted to the handle structure 30. Next, the spring structure 40 and the handle structure 30 are separately assembled onto the assembly post 16 of the support tray 10. Then, the second pin 50 is inserted from the bottom of the support tray 10 into the axial through hole of the assembly post 16. One end of the second pin 50 is stepped, and the other end is riveted into the assembly hole 34 of the handle structure 30. Thus, the handle structure 30 is assembled onto the support tray 10. Then, the first telescopic knob 22 is welded onto the component to be supported 20, thereby completing the assembly of the tool-free disassembly module 2.

[0053] Specific usage methods and working principles:

[0054] When installing the component to be supported 20, firstly, align the first guide sliding structure 12 (gourd hole) on the component to be supported 20 with the first guide sliding structure 12 (H-beam nail) on the support tray 10 and install it onto the support tray 10. Then, push the component to be supported 20 into the direction of the gourd hole. When the second inclined surface 2211 on the first telescopic knob 22 touches the first inclined surface on the support tray 10, the first telescopic rod 221 on the first telescopic knob 22 moves upward under the interaction of the second inclined surface 2211 and the first inclined surface. After the component to be supported 20 is installed in place, the first telescopic rod 221 on the first telescopic knob 22 extends under the action of gravity and is locked in the first limiting hole 131 on the support tray 10. The component to be supported 20 will be fixed in the left, right and up and down directions by the first guide sliding structure 12 at the four corners of the support tray 10. The first telescopic rod 221 on the first telescopic knob 22 and the first limiting hole 131 on the support tray 10 are fixed in the left, right and up and down directions. Hole 131 fixes the front-to-back direction, so the carrier 20 will be firmly fixed on the carrier tray 10. Then, the assembled tool-free disassembly module 2 is installed into the module fixing frame 1. The steps are: open the handle structure 30 on the tool-free disassembly module 2, align it with the guide rail 104 on the limiting beam 103 of the module fixing frame 1, and insert it into the first pull hole 102. After installation, rotate the handle structure 30. After rotation, the limiting protrusion 33 at the other end of the handle structure 30 will... It will get stuck in the snap-fit ​​hole 101 of the module fixing frame 1. Finally, press and rotate the second telescopic knob 32 clockwise. The square mushroom head of the second telescopic rod 321 will extend into the limiting boss 17 at the locking hole 15 and form a cross shape with the limiting boss 17. Then release it. The square mushroom head of the second telescopic rod 321 will be stuck in the step of the limiting boss 17 at the locking hole 15 and cannot be rotated. From this point on, the tool-free disassembly module 2 is firmly fixed in the module fixing frame 1.

[0055] When the load-bearing component 20 malfunctions, pull the module fixing frame 1 out from the second pull-out hole 3021 of the chassis body 3, then press and rotate the second telescopic knob 32 counterclockwise. The square mushroom head of the second telescopic rod 321 will extend and align with the limiting boss 17 at the locking hole 15. Then release the knob, and the square mushroom head of the second telescopic rod 321 will retract into the second telescopic knob 32. The handle structure 30 will automatically open under the force of the spring structure 40. Then, pull the tool-free disassembly module 2 out from the module fixing frame 1. Thus, the tool-free disassembly module 2 is removed from the module fixing frame 1. When the carrier 20 is activated, the first telescopic knob 22 is rotated clockwise. The first limiting spiral groove 2231 on the first telescopic knob 22 will press the first pin 224 to move upward. Since the first pin 224 is inserted into the first telescopic rod 221, it will drive the first telescopic rod 221 to move upward. When the first telescopic knob 22 is rotated to the position, the first pin 224 will be fixed at the highest point of the first limiting spiral groove 2231. The first telescopic rod 221 will be driven by the first pin 224 to retract into the first telescopic knob 22. Then the carrier 20 can move towards the large hole of the gourd. After moving to the large hole of the gourd, the carrier 20 can be taken out.

[0056] In conclusion, the disassembly of the support component 20 is now complete. The entire installation and disassembly process is tool-free and simple to operate.

[0057] like Figure 4 and Figure 5 As shown, the module fixing assembly includes a module fixing frame 1 and a tool-free disassembly module 2. The module fixing frame 1 has at least one first pull-out hole 102. The tool-free disassembly module 2 is slidably disposed at the first pull-out hole 102. The tool-free disassembly module 2 is the tool-free disassembly module described above and below. This ensures convenient assembly between the module fixing frame 1 and the tool-free disassembly module 2.

[0058] Furthermore, the module fixing frame 1 is provided with a snap-fit ​​hole 101, which is used to engage with the limiting end of the handle structure 30 of the tool-less disassembly module 2 to position and install the tool-less disassembly module 2 onto the module fixing frame 1. In this way, the connection between the module fixing frame 1 and the tool-less disassembly module 2 is reliable.

[0059] like Figure 12As shown, the server chassis includes a chassis body 3 and a module fixing assembly 4. The chassis body 3 has a receiving groove 301 and a component fixing frame 302. The component fixing frame 302 has a second pull-out hole 3021, which communicates with the receiving groove 301. A second protrusion structure 303 is provided at at least one position on the groove wall of the receiving groove 301 and the hole wall of the second pull-out hole 3021. The module fixing assembly 4 is removably disposed at the second pull-out hole 3021 and has a third telescopic knob 401. The module fixing assembly 4 is the aforementioned module fixing assembly. The second protruding structure 303 has a second limiting hole on its end surface. At least a portion of the outer peripheral surface of the second protruding structure 303 is a third inclined surface. The third telescopic knob 401 has a third telescopic rod, and the axial end of the third telescopic rod has a fourth inclined surface for cooperating with the third inclined surface. During the sliding of the module fixing assembly 4 along the second preset direction, the third telescopic rod is pushed to move in a direction away from the second protruding structure 303 by the cooperation of the third and fourth inclined surfaces until the module fixing assembly 4 is installed in place. At least under its own weight, the third telescopic rod falls into the second limiting hole. In this way, by providing the second protruding structure 303 at at least one position on the groove wall of the receiving groove 301 and the hole wall of the second pull hole 3021, and by providing the third telescopic knob 401 on the module fixing assembly 4, tool-free quick installation and disassembly are achieved between the chassis body 3 and the module fixing assembly 4. This ensures the convenience of disassembly and assembly between the chassis body 3 and the module fixing assembly 4, while also saving manpower.

[0060] It should be noted that in this application, the structure of the third telescopic knob 401 is the same as that of the first telescopic knob 22, and the structure of the second protrusion structure 303 is the same as that of the first protrusion structure 13, which will not be described again here.
