Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and in particular to an electronic equipment chassis and an electronic equipment. Background Technology

[0002] In existing electronic equipment chassis structures, intrusion switch assemblies are typically mounted on the inner surface of the chassis top cover to detect its open or closed state. However, since chassis top covers are often made of thin-walled metal or plastic, pressure fluctuations caused by the high-speed rotation of the central fan module during equipment operation, or during suction and lifting operations in automated production, can easily lead to localized deformation of the top cover. This deformation can indirectly compress or pull on the intrusion switch assembly mounted on it, causing malfunctions at the trigger end, resulting in false alarms and affecting system stability and reliability.

[0021] This application discloses an electronic device chassis that integrates a switch assembly on the inner wall of the chassis. The switch is triggered by a trigger structure on the top cover and a spring-loaded trigger on the switch assembly, a design that differs from traditional top-cover-mounted switch assemblies. In this application, when the top cover is normally closed, the trigger structure on its inner surface presses down on the spring-loaded trigger, causing deformation and triggering the switch assembly for status detection. When the top cover undergoes localized deformation due to external impact, thermal deformation, or assembly stress, the switch assembly is not directly mounted on the top cover; both the spring-loaded trigger and the switch assembly are located on the inner wall of the chassis, effectively isolating the top cover deformation from interfering with the switch triggering mechanism. This application employs a structure that combines a trigger structure on the top cover, a switch assembly on the inner wall of the chassis, and a spring-loaded trigger on the switch assembly, significantly improving the reliability and anti-interference capability of the switch assembly and preventing accidental activation of the switch assembly due to top cover deformation. This application employs a structure with an elastic trigger on the switch, utilizing the elastic deformation characteristic of the elastic trigger. When the top cover is closed, the triggering structure on the top cover deforms by pressing against the elastic trigger, triggering the switch. When the top cover is opened, the contact structure releases the elastic trigger, which then resets under elastic action, thus achieving a reset action and no longer triggering the switch. This application further ensures the stability and reliability of the overall structure through the structure of the elastic trigger. Attached Figure Description

[0040] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] To address the issues of poor stability and reliability of switching components in related technologies, this application provides an electronic device chassis 10.

[0042] like Figures 1 to 9 As shown, the electronic device chassis 10 includes a chassis 110, a top cover 120, a switch assembly 20, and a trigger structure 40. The top cover 120 is detachably mounted on the chassis 110. The switch assembly 20 is mounted on the inner side wall of the chassis 110. The switch assembly 20 includes a switch element 210 and an elastic trigger element 211. The elastic trigger element 211 is mounted on the switch element 210. The trigger structure 40 is mounted on the inner surface of the top cover 120. The trigger structure 40 and the elastic trigger element 211 are press-fitted together to drive the elastic trigger element 211 to trigger the switch element 210.

[0043] The top cover 120 is installed at the top opening of the enclosure 110. The top cover 120 has an open position and a closed position. The switch assembly 20 is installed on the side wall of the enclosure 110 to detect the open and closed position of the top cover 120. Compared with the top cover 120, which is prone to local deformation due to external force or temperature changes, the side wall of the enclosure 110 has stronger rigidity.

[0044] In this embodiment, the electronic device chassis 10 has a switch assembly 20 disposed on the inner wall of the chassis 110. The switch assembly 210 is triggered by the pressing cooperation between the trigger structure 40 disposed on the top cover 120 and the elastic trigger element 211 disposed on the switch element 210. The structural configuration of this application differs from the conventional method of disposing of the switch assembly 20 on the top cover 120. In this application, when the top cover 120 is normally closed, the trigger structure 40 on its inner surface presses the elastic trigger element 211, causing it to deform and triggering the switch element 210, thereby realizing state detection. When the top cover 120 undergoes local deformation due to external impact, thermal deformation, or assembly stress, since the switch assembly 20 is not directly mounted on the top cover 120, both the elastic trigger element 211 and the switch element 210 are located on the inner wall of the chassis 110, thereby effectively isolating the interference of the deformation of the top cover 120 on the switch triggering mechanism.

[0045] It should be further explained that, currently, when the top cover 120 of the chassis deforms, the deformation area mainly occurs in the middle area of ​​the top cover 120. However, the present application uses a switch assembly 20 located on the inner side wall of the chassis to avoid the area of ​​the top cover 120 that is prone to deformation, thereby improving the stability of the installation structure of the switch assembly 20 and ensuring the reliability of the switch assembly 20 in detecting the state of the top cover 120.

[0046] This application employs a structure that combines a trigger structure 40 on the top cover 120, a switch element 210 located on the inner wall of the housing 110, and an elastic trigger element 211 located on the switch element 210. This significantly improves the reliability and anti-interference capability of the switch assembly 20 and avoids the problem of accidental activation of the switch assembly 20 due to deformation of the top cover 120. Furthermore, the structure of the elastic trigger element 211 on the switch element 210 utilizes its elastic deformation characteristic. When the top cover 120 is closed, the trigger structure 40 on the top cover 120 deforms by pressing against the elastic trigger element 211, triggering the switch element 210. When the top cover 120 is opened, the contact structure releases the elastic trigger element 211, which then resets under elastic action, thus achieving a reset action and no longer triggering the switch element 210. The structure of the elastic trigger element 211 further ensures the stability and reliability of the overall structure.

[0047] In this embodiment, the elastic trigger 211 is a spring sheet. The first end of the spring sheet is connected to the switch 210, and the second end of the spring sheet is suspended to form an elastic cantilever. Specifically, the spring sheet is located on the top surface of the switch 210 for abutting with the trigger structure 40. The switch 210 has a trigger end. When the top cover 120 is closed at the top opening of the housing 110, the trigger structure 40 presses against the second end of the spring sheet, and the spring sheet deforms to contact the trigger end of the switch 210, making the switch 210 conductive. At this time, the top cover 120 can be detected to be closed by the switch assembly 20. When the top cover 120 is opened, as the top cover 120 moves the trigger structure 40, the trigger structure 40 and the spring sheet are spaced apart. The trigger structure 40 releases the spring sheet, the spring sheet resets, and releases the pressure from the trigger end. At this time, the switch 210 is deconductive, and the top cover 120 is detected to be open. The structural design of this application utilizes the elastic deformation of the spring to achieve the triggering action. This structural design effectively avoids the problem of false triggering or trigger failure caused by deformation of the top cover 120 or assembly deviation, and significantly improves the stability and reliability of the switch triggering.

[0048] like Figure 7 As shown, the trigger structure 40 is detachably mounted on the top cover 120, and the trigger structure 40 is a trigger plate.

[0049] The trigger structure 40 is detachable, allowing it to be replaced or repaired independently of the top cover 120. This avoids the need to replace the entire top cover 120 due to damage or failure of the trigger structure 40, significantly improving maintenance efficiency and cost control. The trigger structure 40 is specifically a trigger plate, whose structure provides stable support and precise positioning, ensuring the consistency of the triggering action.

[0050] Specifically, the trigger plate has a protrusion for triggering the spring, the protrusion being positioned facing away from the inner surface of the top cover 120.

[0051] In this embodiment, the trigger plate is provided with a protruding portion for triggering the elastic trigger 211. The protruding portion is oriented towards the side away from the inner surface of the top cover 120, so that during the closing process of the top cover 120, the protruding portion can be directly facing the suspended end of the elastic trigger 211 and apply force along its deformation direction, ensuring that the force path of the elastic trigger 211 is completely consistent with the triggering direction, thereby realizing stable and reliable triggering of the switch 210 and avoiding triggering failure caused by incorrect assembly direction or structural interference. At the same time, the orientation design of the protruding structure will not interfere with the inner wall of the housing 110 when the top cover 120 is disassembled, ensuring the smoothness and safety of the disassembly and assembly process.

[0052] like Figure 8 and Figure 9As shown, the switch assembly 20 also includes a carrier plate 220 and a cover plate 230. The carrier plate 220 is connected to the inner wall of the housing 110, and the cover plate 230 is installed on the carrier plate 220. The cover plate 230 is located on the side of the carrier plate 220 facing the inner wall of the housing 110. Along the width direction of the housing 110, the switch element 210 is installed between the carrier plate 220 and the cover plate 230.

[0053] In this embodiment, the switch assembly 20 is stably connected to the inner wall of the housing 110 via the carrier plate 220, providing a rigid support base for the switch component 210. At the same time, the cover plate 230 is installed on the carrier plate 220 and located on the side of the carrier plate 220 facing the inner wall of the housing 110. Together with the carrier plate 220, it clamps and fixes the switch component 210 from both sides, forming a limiting structure along the width direction of the housing 110. This effectively suppresses the displacement and deflection of the switch component 210 under vibration, assembly or external impact, and avoids false triggering or trigger failure caused by uneven force, thus achieving the protection effect for the switch component 210. The cover plate 230 and the switch 210 are located on the inner side of the carrier plate 220 facing the housing 110, which isolates the switch 210 from direct interference by external foreign objects or stress transmission. Together with the elastic trigger 211 and the trigger structure 40 on the inner surface of the top cover 120, the triggering action is transmitted only through controlled elastic deformation, which significantly improves the stability and reliability of the switch triggering and ensures that the equipment can still accurately respond to the opening and closing state of the top cover 120 under complex working conditions.

[0054] In this embodiment, the switch 210, cover plate 230 and carrier plate 220 are connected in a detachable manner to facilitate independent replacement and maintenance of the switch 210, cover plate 230 and carrier plate 220 in the future, thereby improving the convenience of operation.

[0055] In one embodiment, such as Figure 8 and Figure 9 As shown, the switch 210 also includes a fastener 240, which passes through the cover plate 230 and the switch 210 and is connected to the carrier plate 220. The cover plate 230 and the switch 210 are locked to the carrier plate 220 by the fastener 240.

[0056] In this embodiment, the fastener 240 penetrates the cover plate 230 and the switch component 210 and connects to the carrier plate 220, so that the cover plate 230 and the switch component 210 are synchronously locked and fixed to the carrier plate 220, effectively suppressing the relative displacement between the two in the transportation or vibration environment, and avoiding trigger failure due to loosening. The fastener 240 can be a structural component such as a bolt.

[0057] In one embodiment, such as Figure 8 and Figure 9As shown, at least one end of the cover plate 230 along the length of the housing 110 is engaged with the carrier plate 220. This engagement of the cover plate 230 with the carrier plate 220 along the length of the housing 110 forms a mechanical limiting constraint along the length, improving the stability of the installation of the switch component 210, the cover plate 230, and the carrier plate 220. Furthermore, the engaging structure facilitates quick disassembly and assembly of the switch component 210, the cover plate 230, and the carrier plate 220, thus improving assembly convenience.

[0058] The snap-fit ​​can be located at one end of the cover plate 230 along the length of the box 110; the snap-fit ​​can also be located at the other end of the cover plate 230 along the length of the box 110; of course, the snap-fit ​​can also be located in the area between the two ends of the cover plate 230 along the length of the box 110.

[0059] Specifically, the snap-fit ​​structure can be a snap-fit ​​between a buckle and a slot, with one of the buckle and slot located on the carrier plate 220 and the other on the cover plate 230; preferably, the cover plate 230 is provided with a buckle and the carrier plate 220 is provided with a slot.

[0060] In this embodiment, the switch 210, cover plate 230, and carrier plate 220 can be assembled individually using fasteners 240; the switch 210, cover plate 230, and carrier plate 220 can also be assembled using only snap-fit; of course, the switch 210, cover plate 230, and carrier plate 220 can also be assembled using both fasteners 240 and snap-fit. In this embodiment, at least one end of the cover plate 230 along the length of the housing 110 is snap-fitted with the carrier plate 220 to form a mechanical limiting constraint along the length direction. This, together with the locking effect of the fasteners 240, constitutes a double fixing structure, significantly improving the overall assembly stability of the switch assembly 20 and ensuring that the elastic trigger 211 and the trigger structure 40 always maintain a precise pressing fit, thereby ensuring the triggering reliability and response consistency of the switch 210 under various working conditions.

[0061] like Figure 8 and Figure 9 As shown, one of the carrier plate 220 and the switch component 210 is provided with a positioning protrusion 250 arranged along the width direction of the housing 110, and the other of the two is provided with a positioning hole 260 that engages with the positioning protrusion 250. The positioning protrusion 250 and the positioning hole 260 are matched in shape; when the positioning protrusion 250 is cylindrical, the positioning hole 260 is also cylindrical.

[0062] In this embodiment, the carrier plate 220 and the switch 210 are laterally limited by the insertion and engagement of the positioning protrusion 250 and the positioning hole 260 provided along the width direction of the housing 110. This ensures that when the switch 210 is clamped between the carrier plate 220 and the cover plate 230, its position along the width direction of the housing 110 is precisely constrained, avoiding lateral displacement caused by deformation of the housing 110 or assembly tolerances. This structure ensures that the elastic trigger 211 always maintains a stable alignment with the trigger structure 40 on the inner surface of the top cover 120. Even if the housing is subjected to external impact or temperature changes that cause slight structural deformation, the consistency and reliability of the trigger action can be maintained, thereby significantly improving the response accuracy and long-term stability of the intrusion switch.

[0063] Specifically, in this embodiment, the structural configuration may be such that a positioning protrusion 250 is provided on the carrier plate 220 and a positioning hole 260 is provided on the switch component 210; or the carrier plate 220 may be provided with a positioning hole 260 and the switch component 210 may be provided with a positioning protrusion 250.

[0064] like Figure 8 and Figure 9 As shown, the inner wall of the housing 110 has a limiting hole, and the carrier plate 220 has a limiting protrusion 223 extending toward the inner wall of the housing 110, at least a portion of the limiting protrusion 223 extending into the limiting hole.

[0065] The shapes of the limiting hole and the limiting protrusion 223 are matched, that is, when the limiting protrusion 223 is cylindrical, the corresponding limiting hole is also cylindrical.

[0066] In this embodiment, a limiting hole is provided on the inner sidewall of the housing 110, and a limiting protrusion 223 is provided on the carrier plate 220 extending toward the inner sidewall of the housing 110. At least a portion of the limiting protrusion 223 extends into the limiting hole. Through the synergistic effect of this structure and the connection relationship between the carrier plate 220 and the inner sidewall of the housing 110, the displacement of the carrier plate 220 in the lateral and longitudinal directions is effectively limited. This ensures that the switch assembly 20, composed of the switch element 210, the elastic trigger element 211, and the cover plate 230, maintains a stable relative position during transportation or vibration. This prevents the elastic trigger element 211 from being misaligned with the trigger structure 40 on the inner surface of the top cover 120 due to the offset of the carrier plate 220. This ensures that the elastic trigger element 211 always maintains a precise pressing fit with the trigger structure 40, thereby improving the reliability and response consistency of the intrusion switch trigger.

[0067] In this embodiment, as Figure 9As shown, the carrier plate 220 includes a first plate segment 221 and a second plate segment 222. The first plate segment 221 is spaced apart from the inner side wall of the housing 110 to form an installation space. The cover plate 230 and the switch 210 are located in the installation space and connected to the first plate segment 221, and are arranged on both sides of the first plate segment 221 along the length direction of the housing 110. The second plate segment 222 is attached to the inner side wall of the housing 110 and connected to the inner side wall of the housing 110.

[0068] Specifically, the carrier plate 220 forms an installation space by being spaced apart from the inner wall of the housing 110 by the first plate segment 221, so that the cover plate 230 and the switch 210 are stably accommodated in the space, avoiding false triggering caused by the direct transmission of force deformation of the side wall of the housing 110 to the switch 210; at the same time, the second plate segment 222 is set on both sides of the first plate segment 221 along the length direction of the housing 110, and is tightly attached and connected to the inner wall of the housing 110, forming a double-sided rigid constraint along the length direction, which effectively improves the overall installation rigidity and positioning accuracy of the carrier plate 220 on the inner wall of the housing 110, ensuring that the switch 210 and the elastic trigger 211 always maintain axial alignment and stable pressing relationship under the action of the trigger structure 40 on the inner surface of the top cover 120, thereby significantly enhancing the reliability and vibration resistance of the intrusion switch triggering, and fundamentally solving the problem of trigger failure caused by loosening or offset of the installation structure.

[0069] The electronic device chassis 10 in this embodiment also includes a cable management assembly 30, such as... Figures 3 to 6 As shown, the cable management assembly 30 and the switch assembly 20 are mounted on the same inner side wall of the housing 110.

[0070] Specifically, such as Figure 10 As shown, the cable management assembly 30 includes a plate structure 310 and an expansion module 320. The plate structure 310 and the switch assembly 20 are mounted on the same inner side wall of the enclosure 110. At least a portion of the plate structure 310 is spaced apart from the inner side wall of the enclosure 110 for cable routing. The expansion module 320 is mounted on the plate structure 310 and is located on the side of the plate structure 310 away from the inner side wall of the enclosure 110.

[0071] In this embodiment, the switch assembly 20 is installed on the inner wall of the enclosure 110. Its elastic trigger 211 cooperates with the trigger structure 40 on the inner surface of the top cover 120 to reliably trigger the switch assembly 210. At the same time, by setting a plate structure 310 on the same inner wall of the enclosure 110, and keeping at least a part of the plate structure 310 at a distance from the inner wall of the enclosure 110, a dedicated channel for cable routing is formed, which effectively utilizes the originally unused space below the installation area of ​​the switch assembly 20 and avoids the mess caused by the random routing of cables inside the enclosure. On this basis, the expansion module 320 is installed on the side of the plate structure 310 away from the inner wall of the enclosure 110, so that the expansion module 320 directly relies on the structural support above the cable routing channel. This achieves the integration of cable management and hardware expansion functions without increasing the additional installation space, significantly improving the utilization rate of the internal space of the enclosure, simplifying the assembly process, and enhancing the scalability and maintenance convenience of the equipment.

[0072] In this embodiment, the expansion module 320 is an M.2 module used to install an M.2 interface hard drive.

[0073] like Figure 11 As shown, along the length of the box 110, at least one end of the plate structure 310 has an elastic arm 311. One of the elastic arm 311 and the inner sidewall of the box 110 is provided with a through hole, and the other is provided with a protrusion adapted to the shape of the through hole. The protrusion and the through hole are inserted into each other.

[0074] Among them, the vias and protrusions are designed to be compatible in shape.

[0075] In this embodiment, the elastic arm 311 and the inner wall of the housing 110 are mechanically positioned by the insertion of the protrusion and the through hole. This structure effectively constrains the displacement of the plate structure 310 in the length direction without relying on the fastener 240, preventing it from shifting due to assembly stress or equipment vibration. At the same time, the plate structure 310 and the inner wall of the housing 110 are still spaced apart to ensure that the cable can run smoothly in the gap. The expansion module 320 is installed on the side of the plate structure 310 away from the inner wall of the housing 110, and its positional stability is also enhanced by the reliable positioning of the plate structure 310. Thus, while ensuring the order of cable laying, the installation reliability and electrical connection stability of the expansion module 320 are improved. The elasticity of the elastic arm 311 can also compensate for manufacturing tolerances, so that the insertion of the protrusion and the through hole is both stable and easy to disassemble and assemble, realizing the synergistic optimization of structural positioning and assembly convenience.

[0076] Meanwhile, the inner walls of the plate structure 310 and the box 110 of this application are formed to be hooked together. One of the inner walls of the plate structure 310 and the box 110 is provided with a hook hole 312, and the other is provided with a hook post extending along the width direction of the box 110. The hook post passes through the hook hole 312 and is supported on the inner wall surface of the hook hole 312. The hook hole 312 and the hook post are hooked together.

[0077] In this embodiment, the mounting post penetrates the mounting hole 312 and is supported on the inner wall of the mounting hole 312, so that the plate structure 310 and the inner side wall of the box 110 form a mounting fit. This structure can achieve stable positioning of the plate structure 310 in the height direction and perpendicular to the extension direction of the mounting post without the need for additional fasteners 240. It effectively prevents the plate structure 310 from being displaced due to equipment vibration or external force, ensures that the cable is laid out in an orderly manner in the wiring space formed between the plate structure 310 and the inner side wall of the box 110, and at the same time ensures that the expansion module 320 installed on the side of the plate structure 310 away from the inner side wall of the box 110 remains firm and reliable, improving the vibration resistance and assembly consistency of the overall structure.

[0078] In this embodiment, the mounting post is an I-beam nail. The mounting post has a first section and a second section extending along the width direction of the box 110. The first section is connected to the inner sidewall of the box 110, and the second section is connected to the end of the first section away from the inner sidewall of the box 110. The diameter of the first section is smaller than the diameter of the second section. The mounting hole 312 has a limiting hole section 3121 and an enlarged hole section 3122 communicating along the length direction of the box 110. The limiting hole section 3121 is used to support the first section. The outer edge of the limiting hole section 3121 is limited and fitted with the second section along the width direction of the box 110. The enlarged hole section 3122 is used for the second section to pass through.

[0079] In this embodiment, the first and second segments of the hanging post extend sequentially along the width direction of the housing 110, and the diameter of the first segment is smaller than that of the second segment. This allows the first segment to pass through the enlarged section 3122 of the hanging hole 312 during assembly, and then rotate or slide the second segment into the limiting hole section 3121. At this time, the outer edge of the limiting hole section 3121 and the second segment form an axial limiting fit along the width direction of the housing 110, preventing the hanging post from retracting along the insertion direction. At the same time, the limiting hole section 3121 provides radial support to the first segment, ensuring that the hanging post is not easily deflected or loosened when subjected to force. Thus, without the need for additional fastening elements such as screws or clips, a stable connection between the plate structure 310 and the inner wall of the housing 110 is achieved. This effectively solves the problems of easy dislodgement of the hanging post, limited assembly direction, and poor stability after assembly caused by insufficient axial limiting, and improves the assembly efficiency and reliability of the overall structure.

[0080] Furthermore, each mounting hole 312 and mounting post is correspondingly provided, and each mounting hole 312 can obtain an independent and precise support point through the corresponding mounting post, avoiding misalignment or loosening caused by the accumulation of fit tolerances. At least one mounting hole 312 can be provided; one or more can be provided. When multiple mounting holes 312 are provided, they are spaced apart along the length of the housing 110, so that the plate structure 310 forms multiple points of uniform load-bearing in the length direction, effectively dispersing external forces and thermal stress, and improving the overall installation rigidity and deformation resistance. In this embodiment, three mounting holes 312 are preferably provided. Preferably, the multiple mounting holes 312 are equidistant from each other.

[0081] Furthermore, at least one end of the plate structure 310 has an elastic arm 311. The elastic arm 311 and the mounting hole 312 are spaced apart along the length of the box 110, so that the elastic arm 311 and the mounting hole 312 together form a constraint system. During installation, the elastic arm 311 can provide preload to compensate for assembly gaps and counteract displacement tendencies caused by manufacturing errors or thermal expansion and contraction.

[0082] Furthermore, at least one end of the plate structure 310 has an elastic arm 311, and the distance between the elastic arm 311 and the mounting hole 312 and the bottom surface of the housing 110 is equal. The equal distance between the elastic arm 311 and the mounting hole 312 and the bottom surface of the housing 110 ensures that the plate structure 310 remains horizontally aligned in the vertical direction, avoiding warping or tilting due to center of gravity shift or uneven force. This achieves high-precision and stable positioning of the plate structure 310 in both length and height dimensions, significantly improving its reliability and long-term stability in supporting the expansion module 320 and wiring structure.

[0083] like Figures 11 to 13 As shown, the expansion module 320 includes an expansion plate 321, which is snapped onto the plate structure 310. The cable management assembly 30 also includes a clamping structure 340, which includes at least an elastic member 341. The plate structure 310 has a bracket 313, on which a clamping groove is formed. The expansion plate 321 has an extension arm that extends into the clamping groove. The elastic member 341 abuts against the extension arm and the bracket 313 to limit the extension arm.

[0084] In this embodiment, the expansion plate 321 is quickly assembled with the plate structure 310 through a snap-fit ​​structure. Its extension arm extends into the clamping groove formed on the bracket 313, and the elastic element 341 continuously presses against the extension arm and the bracket 313, forming a bidirectional limiting and constant preload force. This ensures that the expansion plate 321 can maintain a stable position when subjected to mechanical vibration or external impact, avoiding electrical connection failure or signal interruption due to loosening or detachment. At the same time, the elastic restoring force of the elastic element 341 can adaptively compensate for the small displacement caused by thermal expansion and contraction or long-term use, ensuring that the snap-fit ​​stability remains consistent with changes in working conditions. This structure achieves reliable fixation of the expansion module 320 without the need for screws or solder joints, improving assembly efficiency and maintenance convenience, and does not affect the cable routing space of the cable management assembly 30.

[0085] Specifically, the clamping structure 340 also includes a limiting ball 342. The two sides of the clamping groove are provided with mounting channels 314. The side of the extension arm opposite to the mounting channel 314 has an arc-shaped limiting concave surface. Each mounting channel 314 is equipped with an elastic element 341 and a limiting ball 342. The elastic element 341 is located inside the mounting channel 314, and one end is connected to the bracket 313 and the other end is connected to the limiting ball 342. A part of the limiting ball 342 is located in the mounting channel 314, and the other part of the limiting ball 342 abuts against the limiting concave surface.

[0086] In this embodiment, the limiting ball 342 is partially embedded in the mounting channel 314, and the other part of the limiting ball 342 elastically abuts against the limiting concave surface. When the expansion plate 321 is inserted into the clamping groove, the limiting ball 342 moves along the arc-shaped limiting concave surface under the pre-tightening force of the elastic element 341, forming a point-like bidirectional constraint, which effectively suppresses the micro-displacement of the expansion plate 321 in the lateral and longitudinal directions, avoids loosening or displacement caused by vibration or external force, and significantly improves the positioning stability between the expansion module 320 and the plate structure 310. At the same time, the arc-shaped limiting concave surface and the spherical surface of the limiting ball 342 allow for a certain angle of adaptive fitting, taking into account both installation convenience and connection reliability, and ensuring the continuous and stable electrical connection between the expansion plate 321 and the M.2 module.

[0087] In this embodiment, the cable management assembly 30 further includes an extension plate 330, which is snapped onto the plate structure 310 and the expansion plate 321. Along the length direction of the housing 110, the extension plate 330 is located on at least one side of the plate structure 310 and is used to position and support the expansion module 320.

[0088] Specifically, the plate structure 310 of the cable management assembly 30 and the switch assembly 20 are jointly installed on the same inner side wall of the enclosure 110, and at least a portion of the plate structure 310 forms a gap area with the inner side wall of the enclosure 110 for cable laying and passage. The expansion module 320 is disposed on the side of the plate structure 310 away from the inner side wall of the enclosure 110, and is snapped between the plate structure 310 and the expansion plate 321 by an extension plate 330, and extends along the length of the enclosure 110 to at least one side of the plate structure 310. The extension plate 330 provides lateral restraint and structural support for the expansion module 320, effectively suppressing the displacement or overturning tendency of the expansion module 320 along the length of the housing 110 during transportation or vibration conditions. This ensures a stable and reliable electrical and mechanical connection between the expansion module 320 and the plate structure 310, avoiding poor contact or signal interruption caused by structural loosening. At the same time, the snap-fit ​​structure of the extension plate 330 does not require additional fasteners 240, achieving the convenience of modular assembly and the compactness of the overall structure.

[0089] This application also provides an electronic device, including the aforementioned electronic device chassis 10. By setting the switch assembly 20 on the inner side wall of the chassis 110, and cooperating with the trigger structure 40 on the inner surface of the top cover 120, it realizes non-top pressure contact status detection, effectively avoiding the problem of false triggering caused by the deformation of the top cover 120 due to the operation of the fan in the middle of the chassis or suction and transportation. At the same time, the rigidity of the side wall structure is used to improve the triggering stability. The signal line of the switch 210 can be laid along the edge of the side wall groove, reducing cross interference with the motherboard power line and the graphics card data line, improving the cleanliness of the internal wiring and the smoothness of the airflow, and does not affect the adaptation of the CPU heatsink height and the graphics card length. It is suitable for compact chassis design, improving the overall assembly consistency and maintenance convenience.

[0090] When the top cover 120 is closed, the trigger structure 40 installed on the inner surface of the top cover 120 presses against the elastic trigger element 211 of the switch assembly 20. The protruding part of the trigger structure 40 acts on the suspended end of the elastic trigger element 211, causing the elastic trigger element 211 to undergo elastic deformation and contact the trigger end of the switch assembly 210. The switch assembly 210 is turned on, thus identifying that the top cover 120 is in the closed state. When the top cover 120 is opened, the trigger structure 40 separates from the elastic trigger element 211. The elastic trigger element 211 returns to its original shape under its own elastic action and is spaced apart from the trigger structure 40. The switch assembly 210 is turned off, thus identifying that the top cover 120 is in the open state. The switch 210, carrier plate 220, and cover plate 230 are fixed to the inner wall of the housing 110. The first section 221 of the carrier plate 220 is spaced apart from the inner wall of the housing 110 to form an installation space. The switch 210 and cover plate 230 are located within this installation space. The second section 222 of the carrier plate 220 is fitted against and connected to the inner wall of the housing 110. The limiting protrusion 223 extends into the limiting hole in the inner wall of the housing 110. The fastener 240 passes through the cover plate 230 and the switch 210 and is connected to the carrier plate 220. At least one end of the cover plate 230 along the length of the housing 110 is engaged with the carrier plate 220. The positioning protrusion 250 and the positioning hole 26 are connected. The switch assembly 20 is stably connected to the housing 110 during vibration or deformation. The plate structure 310 of the cable management assembly 30 is mounted on the same inner wall of the housing 110 as the switch assembly 20. At least a portion of the plate structure 310 is spaced apart from the inner wall of the housing 110 to form a cable routing channel. The hanging post passes through the hanging hole 312 and is supported on the inner wall of the hanging hole 312. The first section of the hanging post passes through the enlarged hole section 3122 and rotates to limit the second section to the limiting hole section 3121, thereby fixing the plate structure 310. At least one end of the plate structure 310 is provided with an elastic arm 311. The protrusion of the elastic arm 311 is aligned with the inner wall of the housing 110. The through-hole insertion fits together to position the plate structure 310 in the length direction; the expansion plate 321 of the expansion module 320 is snapped into the plate structure 310, the extension arm of the expansion plate 321 extends into the clamping groove on the bracket 313, the elastic element 341 abuts between the extension arm and the bracket 313, a part of the limiting ball 342 is located in the installation channel 314 and the other part abuts against the arc-shaped limiting concave surface of the extension arm, realizing the bidirectional elastic limiting of the expansion plate 321; the extension plate 330 is snapped between the plate structure 310 and the expansion plate 321, and is located on at least one side of the plate structure 310 along the length direction of the housing 110, providing lateral support and positioning for the expansion module 320.

[0091] It should be noted that "multiple" in the above embodiments refers to at least two.

[0092] As can be seen from the above description, the embodiments of this application achieve the following technical effects:

[0093] The electronic device chassis 10 of this application sets the switch assembly 20 on the inner wall of the chassis 110. The switch assembly 210 is triggered by the pressing cooperation between the trigger structure 40 set on the top cover 120 and the elastic trigger 211 set on the switch assembly 210. The structural setting of this application is different from the traditional setting of the switch assembly 20 on the top cover 120. In this application, when the top cover 120 is normally closed, the trigger structure 40 on its inner surface presses the elastic trigger 211, causing it to deform and triggering the switch assembly 210 to realize state detection. When the top cover 120 undergoes local deformation due to external impact, thermal deformation or assembly stress, since the switch assembly 20 is not directly installed on the top cover 120, its elastic trigger 211 and the switch assembly 210 are both located on the inner wall of the chassis 110, thereby effectively isolating the interference of the deformation of the top cover 120 on the switch triggering mechanism. This application employs a structure that combines a trigger structure 40 on the top cover 120, a switch element 210 located on the inner wall of the housing 110, and an elastic trigger element 211 located on the switch element 210. This significantly improves the reliability and anti-interference capability of the switch assembly 20 and avoids the problem of accidental activation of the switch assembly 20 due to deformation of the top cover 120. Furthermore, the structure of the elastic trigger element 211 on the switch element 210 utilizes its elastic deformation characteristic. When the top cover 120 is closed, the trigger structure 40 on the top cover 120 deforms by pressing against the elastic trigger element 211, triggering the switch element 210. When the top cover 120 is opened, the contact structure releases the elastic trigger element 211, which then resets under elastic action, thus achieving a reset action and no longer triggering the switch element 210. The structure of the elastic trigger element 211 further ensures the stability and reliability of the overall structure.
