Description

Technical Field

[0001] This invention relates to the field of server technology, and in particular to server chassis and servers. Background Technology

[0002] A server is a device that provides computing services. Storage servers require frequent maintenance or replacement of internal components.

[0003] In the prior art, a server includes a protective chassis, which includes a front panel and a chassis frame. The front panel of the chassis is mounted on the chassis frame with screws to enable the front panel to be installed and removed.

[0004] However, when staff maintain or replace the internal components of the chassis, the front panel needs to be removed. The front panel, which is screwed onto the chassis frame, needs to be removed with tools. The subsequent installation is also time-consuming and laborious, meaning that the efficiency of installing and removing the front panel is low. Summary of the Invention

[0005] The purpose of this invention is to provide a server chassis and server to solve the technical problem of low efficiency in installing and removing the front panel of a server chassis in the prior art. The specific technical solution is as follows:

[0006] In a first aspect of the present invention, a server chassis is provided, including a chassis frame and a front panel snapped onto the chassis frame, wherein the front panel is provided with a hook, and the chassis frame is provided with a first through hole and a snap-fit ​​flange provided on one side of the first through hole.

[0007] The hook has a engaged state and a free state. When the hook is engaged, the hook contacts the first surface of the engagement fold away from the first through hole. When the hook is free, the hook can be disengaged from the first through hole along a first direction. A lever is hinged to the chassis frame. When the lever is rotated, the hook can be moved from the engaged state to the free state.

[0008] Optionally, the latch includes a plate portion disposed on the front panel and a hook portion connected to the plate portion, the hook portion having a second surface for contacting the first surface of the latching folded edge;

[0009] The lever includes a rod portion and a toggle portion disposed on the rod portion. The toggle portion has a toggle surface. When the lever rotates, the toggle surface is used to press against the end of the hook portion away from the second surface, so that the hook can move from a engaged state to a free state.

[0010] Optionally, the actuating part is provided with a first groove, and when the hook is in the engaging state, the hook extends into the first groove.

[0011] Optionally, the actuating part includes a limiting plate, which is used to contact the third surface of the snap-fit ​​folded edge near the limiting plate.

[0012] Optionally, the snap-fit ​​folded edge has a fourth surface disposed opposite to the third surface, and when the snap hook is in the snap-fit ​​state, the snap hook is in contact with the fourth surface of the snap-fit ​​folded edge.

[0013] Optionally, the hook portion further includes a fifth surface facing the actuating portion, the fifth surface being an arc surface.

[0014] Optionally, the front panel is provided with at least two hooks, and the rod is provided with two actuating parts at intervals, with each actuating part corresponding to one of the hooks.

[0015] Optionally, a lever is provided on the rod, the lever is located between the two actuating parts, and a first notch corresponding to the lever is provided on the chassis frame.

[0016] Optionally, the chassis frame includes an outer surface and an inner surface disposed opposite to each other, the snap-fit ​​flange is disposed on the inner surface, and a support rod is disposed on the front panel, the support rod being used to contact the outer surface of the chassis frame.

[0017] In a second aspect of the present invention, a server is also provided, comprising the server chassis described in any one of the preceding claims.

[0018] The server chassis provided in this embodiment of the invention has a front panel that is snapped onto the chassis frame without the need for screws, saving time and effort during installation and disassembly. Furthermore, during installation, the front panel is simply snapped onto the snap-fit ​​edge along the first through hole. During disassembly, simply rotating the lever moves the hook from the snap-fit ​​state to a free state, and then the free hook is released from the first through hole along the first direction. Installation and disassembly are simple and require no tools, improving the efficiency of installing and disassembling the front panel and chassis frame. In addition, the lever design allows the hook to move from the snap-fit ​​state to the free state, providing a basis for increasing the engagement between the hook and the snap-fit ​​edge. This avoids the problem of insufficient engagement between the front panel and chassis frame due to prioritizing easy disassembly, which could lead to disengagement, thus ensuring the reliability of the snap-fit ​​connection between the front panel and chassis frame.

Detailed Implementation

[0033] The technical solutions of the present invention will now be described with reference to the accompanying drawings in the embodiments of the present invention.

[0034] The embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. The invention is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the invention.

[0035] A server is a device that provides computing services. Storage servers require frequent maintenance or replacement of internal components. In existing technology, a server includes a protective chassis, which consists of a front panel and a chassis frame. The front panel is mounted to the chassis frame with screws to allow for its removal and installation.

[0036] However, when staff maintain or replace the internal components of the chassis, the front panel needs to be removed. The front panel, which is screwed onto the chassis frame, needs to be removed with tools. The subsequent installation is also time-consuming and laborious, meaning that the efficiency of installing and removing the front panel is low.

[0037] To address the aforementioned problems, in a first aspect, embodiments of the present invention provide a server chassis. A server chassis is a freestanding or self-supporting enclosure for housing electrical or electronic equipment. A motherboard, central processing unit (CPU), graphics processing unit (GPU), memory, etc., can be placed or installed inside the server chassis. The server chassis mentioned above will be described in detail below.

[0038] Reference Figures 1 to 4 The server chassis includes a chassis frame 20 and a front panel 10 that is snapped onto the chassis frame 20. The front panel 10 is provided with a hook 11. The chassis frame 20 is provided with a first through hole 21 and a snap-fit ​​flange 22 provided on one side of the first through hole 21. The hook 11 has a snap-fit ​​state and a free state. When the hook 11 is in the snap-fit ​​state, the hook 11 is in contact with the first surface 221 of the snap-fit ​​flange 22 away from the first through hole 21. When the hook 11 is in the free state, the hook 11 can be disengaged from the first through hole 21 along a first direction. A lever 30 is hinged to the chassis frame 20. When the lever 30 is rotated, the hook 11 can be moved from the snap-fit ​​state to the free state.

[0039] Specifically, the server chassis can be a chassis used in storage servers. Storage servers are servers used to store, protect, manage, and access digital data and files, supporting the storage and access of small and large amounts of data via shared networks or the Internet. The chassis frame 20 can be made of metal, such as aluminum alloy, which is lightweight and has excellent heat dissipation; or it can be made of hot-dip galvanized steel, which is rust-proof, corrosion-resistant, and weather-resistant. The front panel 10 is the door and window of the server chassis, protecting the button interfaces and shielding internal components. The front panel 10 can be made of plastic or alloy.

[0040] The server chassis can be a rectangular chassis, with dimensions in the length, width, and height directions. The length direction of the server chassis can be referenced... Figure 3 The direction indicated by the arrow C in the middle indicates the width direction of the server chassis. Figure 3 The direction indicated by the arrow D in the middle indicates the height direction of the server chassis. Figure 4 The direction indicated by arrow E. The hook 11 can be fixed to the front panel 10. If the hook 11 is integrally formed with the front panel 10, when the hook 11 is fixedly connected to the front panel 10, the movement of the front panel 10 will cause the hook 11 to move, and the movement of the hook 11 will also cause the front panel 10 to move. The front panel 10 may have at least one hook 11, such as one, two, three, four, five, etc. (Refer to...) Figure 5 The front panel 10 has four latches 11, which are spaced apart along the length of the server chassis and all located on the same side of the width of the server chassis. The first through hole 21 and the snap-fit ​​flange 22 correspond one-to-one with the latches 11, that is, the number of first through holes 21 and the number of snap-fit ​​flanges 22 are the same as the number of latches 11.

[0041] Reference Figure 6 and Figure 7 The chassis frame 20 includes a rectangular back panel and mounting flanges fixed to the perimeter of the back panel. The mounting flanges include a first mounting flange 28 and a second mounting flange arranged opposite each other along the width direction of the server chassis. A first through-hole 21 is specifically formed on the back panel of the chassis frame 20. When multiple first through-holes 21 are provided, all of them are located close to the first mounting flange 28 and are spaced apart along the length direction of the server chassis. A snap-fit ​​flange 22 can be fixed to the side of the first through-hole 21 opposite to the first mounting flange 28, and the snap-fit ​​flange 22 is perpendicular to the back panel of the chassis frame 20. The first direction specifically refers to the height direction of the server chassis. (See reference...) Figure 11The snap-fit ​​flange 22 has a first surface 221 that is away from the first through hole 21. (Refer to...) Figure 4 , Figure 4 The latch 11 is in the latched state. When the latch 11 is in the latched state, it is in contact with the first surface 221 of the latching flange 22. At this time, if the latch 11 is moved along the first direction toward the first through hole 21, the movement of the latch 11 will be restricted by the latching flange 22. That is, at this time, it can be ensured that the latch 11 is latched onto the chassis frame 20, thereby realizing the installation of the front panel 10 and the chassis frame 20. The amount of engagement between the latch 11 and the latching flange 22 can be referred to Figure 4 W1 in the middle.

[0042] Reference Figures 9 to 11 , Figure 11 The latch 11 is in a free state. When the latch 11 is in a free state, it can be disengaged from the first through hole 21 along the first direction. After the latch 11 is disengaged from the first through hole 21, the front panel 10 and the chassis frame 20 can be detached. It should be noted that the latch 11 in the free state is located between the snap-fit ​​folding edge 22 and the first mounting folding edge 28, and does not contact either the snap-fit ​​folding edge 22 or the first mounting folding edge 28. The lever 30 has an axial direction, which is consistent with the length direction of the server chassis. When the lever 30 rotates, it rotates around its axis. The rotation angle of the lever 30 can be set according to actual needs, such as the rotation angle of the lever 30 being greater than or equal to 10 degrees and less than or equal to 90 degrees. When the hook 11 is in the engaged state, the lever 30 can be in no contact with the hook 11. Rotating the lever 30 moves the hook 11 from the engaged state to the free state, at which point the lever 30 comes into contact with the hook 11. It should be noted that the position of the hook 11 changes when it moves from the engaged state to the free state. When there are multiple hooks 11, there can be only one lever 30. In this case, rotating one lever 30 can move multiple hooks 11 from the engaged state to the free state. Alternatively, there can be multiple levers 30, with the maximum number of levers 30 being the same as the number of hooks 11. In this case, rotating one lever 30 can move some or one of the multiple hooks 11 from the engaged state to the free state. (See reference...) Figure 1 When there are four hooks 11, there are two levers 30, that is, the rotation of one lever 30 can move two hooks 11 from the locked state to the free state.

[0043] When disassembling the front panel 10 from the chassis frame 20, rotating the lever 30 moves the hook 11 from the engaged state to the free state. Then, the free hook 11 can be disengaged from the first through hole 21 along the first direction. In this embodiment, the disengagement of the hook 11 does not rely on its own elasticity, nor does it require forced disengagement. Therefore, the engagement amount W1 between the hook 11 and the engagement edge 22 can be set relatively large to ensure the reliability of the engagement between the front panel 10 and the chassis frame 20 and prevent disengagement. Specifically, the engagement amount W1 can be set to be greater than or equal to twice the thickness of the engagement edge 22, or less than or equal to three times the thickness of the engagement edge 22. By setting this engagement amount W1, the front panel 10 can still safely land in the engagement area when subjected to various impact / drop / impact tests, ensuring the reliability of the engagement between the front panel 10 and the chassis frame 20 and preventing disengagement.

[0044] The server chassis provided in this embodiment of the invention has a front panel 10 that is snapped onto the chassis frame 20 without the need for screws, saving time and effort during installation and disassembly. Furthermore, when installing the front panel 10, simply snap the hook 11 onto the snap-fit ​​edge 22 along the first through hole 21. When disassembling, simply rotate the lever 30 to move the hook 11 from the snap-fit ​​state to the free state, and then release the free hook 11 from the first through hole 21 along the first direction. This simple installation and disassembly, without the need for tools, improves the efficiency of installing and disassembling the front panel 10 and the chassis frame 20. In addition, the lever 30 allows the hook 11 to move from the snap-fit ​​state to the free state, providing a basis for increasing the engagement between the hook 11 and the snap-fit ​​edge 22. This avoids the problem of insufficient engagement between the front panel 10 and the chassis frame 20 due to the need for easy disassembly, thus ensuring the reliability of the snap-fit ​​between the front panel 10 and the chassis frame 20.

[0045] Reference Figure 5 and Figure 8 The latch 11 includes a plate portion 111 disposed on the front panel 10 and a hook portion 112 connected to the plate portion 111. The hook portion 112 has a second surface 113, which is used to contact the first surface 221 of the latching folded edge 22. The lever 30 includes a rod portion 31 and a toggle portion 32 disposed on the rod portion 31. The toggle portion 32 has a toggle surface 33. When the lever 30 rotates, the toggle surface 33 is used to press against the end of the hook portion 112 away from the second surface 113, so that the latch 11 moves from the latching state to the free state.

[0046] Specifically, the plate portion 111 has a uniform thickness along the width direction of the server chassis, and the plate portion 111 and the hook portion 112 are integrally formed into a hook 11. The second surface 113 is perpendicular to the height direction of the server chassis. The engagement amount W1 is specifically the thickness of the second surface 113 along the width direction of the server chassis. When the hook 11 is in the engaged state, the second surface 113 of the hook portion 112 contacts the first surface 221 of the engaging folded edge 22. Along the height direction of the server chassis, the rod portion 31 has a certain distance from the back plate of the chassis frame 20. The cross-section of the rod portion 31 is circular, and the axis of the lever 30 is the axis of the rod portion 31. The rod portion 31 can rotate around its axis, thereby causing other structures on the rod portion 31 to rotate together. Both ends of the lever 31 are hinged to the chassis frame 20. Specifically, a second through hole 26 is provided on the first mounting flange 28, and a hinge flange 27 is fixed to one side of the second through hole 26. The hinge flange 27 is perpendicular to the length direction of the server chassis, and a hinge hole is provided on the hinge flange 27. The end of the lever 31 is inserted into the hinge hole, and one lever 31 corresponds to two hinge flanges 27. The actuating part 32 corresponding to the hook 11 used by the lever 30 is located between the two hinge flanges 27 corresponding to the lever 30.

[0047] The actuating part 32 is fixed to the rod part 31, and the position of the actuating part 32 corresponds one-to-one with the position of the hook 11. Along the length of the server chassis, the length of the actuating part 32 is less than or equal to the width of the hook 11, and greater than or equal to half the width of the hook 11. The actuating part 32 has an actuating surface 33, as shown in the figure. Figure 4 When the latch 11 is in the latched state, the actuating part 32 is in the first state. At this time, the actuating part 32 is not in contact with the latch 11, and the actuating surface 33 is perpendicular to the width direction of the server chassis. (Refer to...) Figure 4 When the lever 30 rotates counterclockwise, the actuating surface 33 abuts against the end of the hook 112 away from the second surface 113, so that the hook 11 moves from the engaged state to the free state. It should be noted that during the process of the hook 11 moving from the engaged state to the free state, a portion of the actuating surface 33 abuts against the end of the hook 112 away from the second surface 113, and the position of the abutting surface 33 against the hook 112 continuously changes. In this embodiment of the invention, the hook 11 can be engaged with the chassis frame 20 by the hook 112; and the state of the hook 11 can be switched simply by the actuating part 32 corresponding to the position of the hook 11, without requiring the entire lever 31 to be configured as the actuating part 32, thus saving costs and facilitating the manufacturing of the lever 30.

[0048] The actuating part 32 is provided with a first groove 34. When the hook 11 is in the engaged state, the hook 11 extends into the first groove 34. Specifically, when the hook 11 is in the engaged state, the hook part 112 extends into the first groove 34, and at this time, the hook part 112 does not contact the first groove 34. The first groove 34 can be a square groove, and the depth of the first groove 34 can be equal to the radius of the rod part 31. By providing the first groove 34, interference between the actuating part 32 and the hook 11 can be avoided when the hook 11 is in the engaged state, ensuring that the hook 11 and the engaging edge 22 have sufficient engagement amount.

[0049] The actuating part 32 includes a limiting plate 35, which is used to contact the third surface 222 of the snap-fit ​​edge 22 near the limiting plate 35. Specifically, the first groove 34 is located between the limiting plate 35 and the actuating part 32. When the hook 11 is in the snap-fit ​​state and the actuating part 32 is in the first state, the limiting plate 35 is in contact with the third surface 222 of the snap-fit ​​edge 22; when the lever 30 rotates counterclockwise, the limiting plate 35 disengages from the snap-fit ​​edge. Furthermore, when the hook 11 is in the snap-fit ​​state and the actuating part 32 is in the first state, there is a certain gap between the limiting plate 35 and the back plate of the chassis frame 20 to ensure that the limiting plate 35 does not interfere with the chassis frame 20 during the counterclockwise rotation of the lever 30. In this embodiment of the invention, the limiting plate 35 ensures that after the lever 30 rotates counterclockwise to move the hook 11 to a free state, the lever 30 can return to its original position in the first state.

[0050] The snap-fit ​​folded edge 22 has a fourth surface 223 that is disposed opposite to the third surface 222. When the snap hook 11 is in the snap-fit ​​state, the snap hook 11 is in contact with the fourth surface 223 of the snap-fit ​​folded edge 22.

[0051] Specifically, the snap-fit ​​process of the front panel 10 onto the chassis frame 20 is as follows: First, the actuating part 32 is in the first state. Then, the hook 11 extends into the chassis frame 20 from the first through hole 21 along the first direction. During the extension process, the hook 11 does not contact the fourth surface 223 of the snap-fit ​​folded edge 22. After extending a certain distance, the hook 11 is moved along the width direction of the server chassis until it contacts the fourth surface 223 of the snap-fit ​​folded edge 22, thus achieving the snap-fit ​​between the front panel 10 and the chassis frame 20. Along the width direction of the server chassis, the distance between the first mounting folded edge 28 and the snap-fit ​​folded edge 22 is greater than the maximum thickness of the hook 11. In this embodiment of the invention, by setting the hook 11 to contact the fourth surface 223 of the snap-fit ​​folded edge 22 when the hook 11 is in the snap-fit ​​state, the accurate snap-fit ​​position of the hook 11 when snap-fitted onto the chassis frame 20 can be guaranteed.

[0052] The hook portion 112 also includes a fifth surface 114 facing the actuating portion 32, and the fifth surface 114 is an arc surface. Specifically, when the hook 11 is in the engaged state, the fifth surface 114 is not in contact with the actuating portion 32. When the actuating portion 32 rotates counterclockwise from the first state, a portion of the actuating surface 33 abuts against a portion of the fifth surface 114, causing the position of the hook 11 to change and move to a free state. In this embodiment of the invention, by setting the fifth surface 114 to be an arc surface, it is possible to ensure that when the hook 11 is in the engaged state, there is no interference between the hook 11 and the actuating portion 32.

[0053] The front panel 10 is provided with at least two hooks 11, and the rod 31 is provided with two actuating parts 32 at intervals, with each actuating part 32 corresponding to one of the hooks 11.

[0054] Specifically, multiple hooks 11 are arranged at intervals along the length of the server chassis, and all are located on the same side of the width of the server chassis. (See reference...) Figure 5 The front panel 10 has four latches 11, which are spaced apart along the length of the server chassis and all located on the same side of the width of the server chassis. A toggle part 32 corresponds to each latch 11, meaning one toggle part 32 moves one latch 11. When two toggle parts 32 are spaced apart on the lever 31, rotating one lever 30 can move two latches 11 from a latched state to a free state. Therefore, when there are four latches 11, two levers 30 are required. The two levers 30 can be unconnected, meaning the rotation of one lever 30 does not affect the rotation of the other lever 30. It should be noted that when the two levers 30 are unconnected, both levers 30 must rotate simultaneously when the front panel 10 is disassembled from the chassis frame 20. Alternatively, the two levers 30 can be connected, meaning rotating one lever 30 will cause the other lever 30 to rotate as well. In this embodiment of the invention, by providing two actuating parts 32 at intervals on the rod 31, one lever 30 can realize the state change of the two hooks 11, without the need to provide a lever 30 for each hook 11, thus simplifying the structure.

[0055] In other embodiments, when multiple hooks 11 are provided, only one lever 30 may be provided, and the number of actuating parts 32 provided on the lever 31 is the same as the number of hooks 11.

[0056] A lever 36 is provided on the lever 31, and the lever 36 is located between two actuating parts 32. A first notch 23 corresponding to the lever 36 is provided on the chassis frame 20.

[0057] Specifically, each lever 31 is equipped with a lever 36, which allows the lever 31 to be manually rotated around its axis. The first notch 23 is a notch structure that opens towards the first mounting flange 28. Along the length of the server chassis, the length of the first notch 23 is greater than the maximum length of the lever 36. The angle of rotation of the lever 31 around its axis can be set according to actual needs, such as a rotation angle greater than or equal to 10 degrees and less than or equal to 90 degrees. A limiting part can also be provided at the first mounting flange 28 or the first notch 23. When the lever 30 moves the hook 11 from the engaged state to the free state, the limiting part can contact the lever 36, that is, the limiting part is used to limit the tossing angle of the lever 36.

[0058] The design of the paddle 36 allows for quick and easy removal of the front panel 10 from the chassis frame 20 by simply moving the paddle 36. Furthermore, moving the paddle 36 rotates the lever 30, thus changing the state of the latch 11. This clearly indicates the required angle of movement for the paddle 36, preventing breakage of the latch 11 due to excessive operation. The first notch 23 ensures that the paddle 36 will not interfere with the chassis frame 20 during the rotation of the lever 30.

[0059] The disassembly process of removing the front panel 10 from the chassis frame 20 is as follows: pull up the lever 36 provided on the lever 31 counterclockwise in the direction of the first notch 23 so that the lever 31 rotates around its axis, thereby driving the lever 32 to rotate counterclockwise. During the counterclockwise rotation of the lever 32, it will press against the hook 112, causing the position of the hook 11 to change until it moves to a free state; then, the hook 11 is disengaged from the first through hole 21 along the first direction to remove the front panel 10 from the chassis frame 20.

[0060] In other embodiments, instead of a paddle 36 for manually rotating the lever 31, a micro motor can be provided, which is connected to the lever 31 and automatically drives the rotation of the lever 31.

[0061] The chassis frame 20 includes an outer surface 24 and an inner surface 25 that are disposed opposite to each other. A snap-fit ​​flange 22 is disposed on the inner surface 25. A support rod 12 is disposed on the front panel 10. The support rod 12 is used to contact the outer surface 24 of the chassis frame 20.

[0062] Specifically, the back panel of the chassis frame 20 includes an outer surface 24 and an inner surface 25 arranged opposite to each other. The outer surface 24 is close to the front panel 10, and the snap-fit ​​folded edge 22 is fixed to the inner surface 25. The support rod 12 can be fixedly connected to the front panel 10 or detachably connected to the front panel 10. One support rod 12 can be provided, or multiple support rods can be provided according to actual needs. When the latch 11 is in the snap-fit ​​state, the surface of the support rod 12 facing away from the front panel 10 contacts the outer surface 24 of the chassis frame 20. The snap-fit ​​process of the front panel 10 onto the chassis frame 20 is as follows: first, the actuating part 32 is in the position of... Figure 4 In the first state shown, the hook 11 then extends from the first through hole 21 into the chassis frame 20 along the first direction until the surface of the support rod 12 facing away from the front panel 10 contacts the outer surface 24 of the chassis frame 20. Then, the hook 11 is moved along the width direction of the server chassis until it contacts the fourth surface 223 of the snap-fit ​​edge 22, thus achieving the snap-fit ​​between the front panel 10 and the chassis frame 20. In this embodiment of the invention, the support rod 12 ensures an accurate snap-fit ​​position when the hook 11 is snapped onto the chassis frame 20.

[0063] Secondly, embodiments of the present invention provide a server, which may include any of the server chassis described above.

[0064] In one embodiment, the server includes a server chassis, which includes a chassis frame 20 and a front panel 10 snapped onto the chassis frame 20. The front panel 10 has a hook 11. The chassis frame 20 has a first through hole 21 and a snap-fit ​​flange 22 on one side of the first through hole 21. The hook 11 has a snap-fit ​​state and a free state. When the hook 11 is in the snap-fit ​​state, it contacts a first surface 221 of the snap-fit ​​flange 22 away from the first through hole 21. When the hook 11 is in the free state, it can disengage from the first through hole 21 along a first direction. A lever 30 is hinged to the chassis frame 20. Rotating the lever 30 moves the hook 11 from the snap-fit ​​state to the free state. Specifically, the server can be a storage server, which is used for storing, protecting, managing, and accessing digital data and files, supporting the storage and access of small and large amounts of data via a shared network or the Internet. A server chassis is a freestanding or self-supporting enclosure used to house electrical or electronic equipment. In addition to the server chassis, a server also includes a motherboard, central processing unit, graphics processing unit, memory, etc.

[0065] The server provided in this embodiment of the invention has a front panel 10 that is snapped onto the chassis frame 20 without the need for screws, saving time and effort during installation and disassembly.

When disassembling, simply rotate the lever 30 to move the hook 11 from the snap-fit ​​state to the free state, and then release the free hook 11 from the first through hole 21 along the first direction. Installation and disassembly are simple and require no tools, improving the efficiency of installing and disassembling the front panel 10 and the chassis frame 20. In addition, the lever 30 allows the hook 11 to move from the snap-fit ​​state to the free state, providing a basis for increasing the engagement between the hook 11 and the snap-fit ​​edge 22. This avoids the problem of insufficient engagement between the front panel 10 and the chassis frame 20 due to easy disassembly, thus ensuring the reliability of the snap-fit ​​between the front panel 10 and the chassis frame 20. Furthermore, the lever 30 ensures that the front panel 10 can safely land in the engagement area when subjected to various impact / drop / impact tests, thus guaranteeing the reliability of the engagement between the front panel 10 and the chassis frame 20 and preventing detachment.
