Description

Technical Field

[0001] This application relates to the technical field of servers, and particularly to a hard disk bracket and a server having the same. Background Art

[0002] At present, to meet the requirements of flexible expansion and modular maintenance, server chassis generally have multiple standard hard disk slots in the front window area, which are used to install physical hard disks or configure hard disk brackets when vacant. Existing hard disk brackets mostly adopt an integral engineering plastic structure. The main body is a rectangular frame, with flat slideways on both sides for inserting into the hard disk frame of the chassis along the guide rails. There is a handle groove at the front end for easy manual plugging and unplugging. Some products have a simple buckle structure at the rear end to achieve mechanical locking with the chassis. Such a design has a simple structure, low cost, and mature manufacturing process. It can effectively enclose the vacant slots, improve the appearance consistency of the front window of the chassis, and prevent dust from entering and air flow disorder, which has a positive significance for system heat dissipation and cleanliness.

[0003] However, existing hard disk brackets have serious technical defects in terms of electromagnetic compatibility. Most products do not configure any electromagnetic shielding structure and only rely on the overall metal shell of the chassis for shielding, resulting in significant electromagnetic leakage windows formed by the vacant slots. When the server is running, high-frequency electromagnetic radiation generated by components such as internal power supplies, high-speed buses, and hard disk controllers will radiate outward through the unshielded slots. At the same time, external electromagnetic interference is also likely to invade the system, causing signal crosstalk, data errors, and even system downtime. It often fails in electromagnetic compatibility tests due to excessive radiation or insufficient immunity. In addition, the plastic main body itself does not have conductivity and cannot form a low-impedance path with the chassis ground, further weakening the shielding effect. Summary of the Utility Model

[0004] This application provides a hard disk bracket and a server having the same, so as to at least solve the technical problem of relatively low structural strength of the hard disk bracket in the related art.

[0005] This application provides a hard disk bracket for installation in a server hard disk slot, including:

The snap-fit ​​element is disposed on the side of the elastic element away from the end plate, and at least a portion of the snap-fit ​​element extends in a direction away from the end plate.

[0015] Furthermore, each first snap-fit ​​portion also includes an unlocking member, which is disposed on the side of the elastic member near the end plate. At least a portion of the unlocking member extends toward the end plate and protrudes from the main frame. The unlocking member is movably disposed along the length direction of the end plate to cause at least a portion of the elastic member to bend along the length direction of the end plate.

[0016] Furthermore, along the length direction of the end plate, the end plate is spaced apart from both the first side plate and the second side plate.

[0017] Furthermore, the main frame also includes at least one first guide member, at least one second guide member is provided on the hard disk slot corresponding to at least one first guide member, and at least one of the first guide members is provided on the outer wall of the first side plate and / or the second side plate, and each first guide member extends along the extension direction of the first side plate or the second side plate.

[0018] Furthermore, the main frame also includes at least one stop member. At least one of the first panel, the second panel, the first side panel, and the second side panel is provided with at least one of the at least one stop member. The at least one stop member is provided at the end of the main frame away from the hard disk slot. Each stop member extends in a direction away from the end plate. When the hard disk tray is inserted into the hard disk slot, the stop member abuts against the server housing.

[0019] Furthermore, the main frame also includes at least one reinforcing member, and at least one heat dissipation groove is provided on the first panel and / or the second panel, with the groove opening facing away from the end plate.

[0020] Furthermore, at least one reinforcing member is provided on the first panel and / or the second panel, each reinforcing member being provided on the side of the heat dissipation groove near the groove opening, and the two ends of the reinforcing member being connected to the two sides of the heat dissipation groove respectively.

[0026] This application constructs a closed main frame consisting of a first panel, a second panel, a first side panel, a second side panel, and an end plate, forming a box-like or rectangular tube-like spatial three-dimensional structure. This fully enclosed design greatly enhances the overall bending moment and torsional deformation resistance of the tray, effectively overcoming the defects of traditional flat or open frames that are prone to buckling or twisting under stress. Simultaneously, the first and second side panels are positioned opposite each other and rigidly connected to the front and rear panels, forming a stable support skeleton. This not only disperses local stress concentration during insertion, removal, and transportation but also ensures the geometric stability of the structure. Furthermore, the design of the shielding component, which accommodates and partially extends from the limiting hole, creates an interlocking or fitting relationship between the shielding component and the main frame, further enhancing the connection rigidity between components and preventing internal components from loosening. This synergistic effect at both the overall and local levels significantly improves the structural strength, assembly accuracy, and long-term reliability of the hard drive tray. Therefore, it can solve the technical problem of low structural strength in related technologies, achieving the technical effect of improving structural strength and enhancing the stability of the overall electromagnetic environment of the system.

[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] The embodiments of this application provide a hard disk tray, and the device is described in detail in conjunction with the structure and working principle of the hard disk tray.

[0042] like Figures 1 to 8As shown, the hard drive bracket of this application is used to be inserted into the hard drive slot of a server. The hard drive bracket includes a main frame 100 and a shielding assembly 200. The main frame 100 includes a first panel 110, a second panel 120, a first side plate 130, a second side plate 140, and an end plate 150. The first side plate 130 and the second side plate 140 are disposed opposite each other at the same ends of the end plate 150 and are connected to the first panel 110 and the second panel 120. The first panel 110 and the second panel 120 are provided with corresponding limiting holes near the end plate 150. The shielding assembly 200 is accommodated in the space enclosed by the first panel 110, the second panel 120, the first side plate 130, the second side plate 140, and the end plate 150, and partially extends out of the limiting holes.

[0043] The above embodiments solve the technical problem of low structural strength of hard drive trays in the prior art. Specifically, this application constructs a closed main frame 100 formed by a first panel 110, a second panel 120, a first side panel 130, a second side panel 140, and an end plate 150, forming a box-like or rectangular tube-like spatial three-dimensional structure. This fully enclosed design greatly improves the overall bending moment and torsional deformation resistance of the tray, effectively overcoming the defects of traditional flat or open frames that are prone to buckling or twisting under stress. At the same time, the first side panel 130 and the second side panel 140 are arranged opposite each other and rigidly connected to the front and rear panels, forming a stable support skeleton, which not only disperses the local stress concentration during insertion, removal, and transportation, but also ensures the geometric stability of the structure. In addition, the design of the shielding component 200, which accommodates and can partially extend out of the limiting hole, makes the shielding component and the main frame interlocked or fitted, further enhancing the connection rigidity between the components and preventing the internal components from loosening. Thus, it works synergistically at the overall and local levels, significantly improving the structural strength, assembly accuracy, and long-term reliability of the hard drive tray.

[0044] By applying the hard disk tray of the above embodiments of this application, the hard disk tray of this application, through the separate and detachable structural design of the main frame 100 and the shielding component 200, combined with the limiting hole 104 and the shielding body 210, achieves a significant improvement in its electromagnetic compatibility performance without changing the shape and insertion / removal method of the traditional hard disk tray. The main frame 100, as a load-bearing and guiding structure, provides a stable positioning space for the shielding component 200 by enclosing the mounting cavity 101. The limiting hole 104, which is opened in the wall thickness direction of the main frame 100 and communicates with the mounting cavity 101, precisely reserves a channel for the shielding body 210 to extend outward, so that the shielding body 210 can reliably extend from the mounting cavity 101 to the outside without compromising the integrity and structural strength of the main frame 100, and directly form physical contact with the metal inner wall of the hard disk slot. The shielding body 210 is made of a flexible metal material. Its protruding part is squeezed and deformed by the inner wall of the chassis during the insertion of the dummy module into the hard drive slot, generating a continuous and stable contact pressure. This creates a continuous, low-impedance electromagnetic shielding path on the side of the dummy module, effectively sealing the electromagnetic leakage window formed by the plastic material and empty slot of the traditional dummy module.

[0045] In the above embodiments, such as Figure 1 , Figure 2 As shown, the detachable connection between the shielding component 200 and the main frame 100 allows the shielding function to be assembled, replaced, or upgraded independently of the structural frame. This avoids the performance degradation problems caused by the difficulty of maintenance in traditional integrated shielding structures, while also reducing manufacturing and maintenance costs. This structural design ensures that the shielding function does not depend on the overall shielding system of the chassis. Even when only a portion of the slots use real hard drives, each empty slot where the dummy module of this application is installed can still achieve effective shielding independently, significantly improving the stability of the overall electromagnetic environment of the system. Furthermore, since the shielding body 210 only extends partially through the limiting hole 104, its installation does not affect the sliding structure, snap-fit ​​mechanism, or external dimensions of the main frame 100. It is fully compatible with the mechanical interface and assembly process of existing server hard drive frames, achieving seamless integration of electromagnetic shielding function with the original structural design. This solves the technical contradiction that traditional dummy modules must sacrifice structural simplification, maintainability, or versatility when improving electromagnetic shielding performance. Ultimately, without increasing operational complexity or manufacturing costs, the hard drive tray is transformed from a simple mechanical enclosure into a functional component with active electromagnetic shielding capabilities, providing reliable, reusable, and scalable underlying support for the electromagnetic compatibility of server systems operating in high-density, high-frequency environments.

[0046] In the above embodiments, such as Figure 2As shown in the figure, in the present application, the main frame 100 is designed as a five-sided enclosed structure jointly enclosed by the first panel 110, the second panel 120, the first side plate 130, the second side plate 140 and the end plate 150, so that the installation cavity 101 has a complete and stable accommodating space, providing a structural basis for the accurate positioning and reliable installation of the shielding component 200. The first panel 110 and the second panel 120 serve as the upper and lower reference surfaces of the dummy module. They not only carry the opening positions of the limiting holes 104, but also jointly form the rear closed boundary of the installation cavity 101 with the end plate 150, enabling the shielding component 200 to be restricted in a specific area near the end plate 150, ensuring that when the protruding part of it is inserted into the hard disk slot by the dummy module, it accurately aligns with the electromagnetic shielding contact area on the inner wall of the chassis, avoiding shielding failure caused by position deviation. The first side plate 130 and the second side plate 140 are respectively arranged on both sides of the end plate 150 and connected to the first and second panels 120, forming a stable rectangular frame structure. This not only enhances the overall rigidity of the main frame 100, preventing it from being distorted and deformed due to stress during the insertion and extraction process, but also through its lateral restraint effect, keeps the shielding component 200 in planar positioning within the installation cavity 101, avoiding interference or wear between the shielding main body 210 and the edge of the limiting hole 104 caused by shaking or misalignment. The end plate 150 and the opening 102 are oppositely arranged at both ends of the installation cavity 101, forming a one-way assembly path for the shielding component 200, enabling the shielding component 200 to be inserted only from the rear end and protrude forward, ensuring that the elastic contact end of the shielding main body 210 always faces the direction of the metal inner wall of the chassis, achieving the consistency of the shielding function direction. The limiting holes 104 are opened on the first panel 11 and / or the second panel 120, directly corresponding to the upper and lower extending structures of the shielding main body 210, enabling the shielding main body 210 to complete the protruding action without changing the thickness or increasing the volume, which not only ensures the shielding efficiency but also maintains the compatibility of the overall size of the dummy module with the standard hard disk slot. Without increasing the material usage, this main frame realizes the triple coordination of structural strength, component positioning and shielding direction through geometric layout optimization, enabling the shielding component 200 to achieve stable, reliable and repeatable contact with the metal wall of the hard disk slot without additional fastening and without changing the chassis structure, thus providing necessary and sufficient mechanical guarantee for the realization of the electromagnetic shielding function at the physical structure level.

[0047] In some embodiments, the first panel 110, the second panel 120, the first side plate 130, the second side plate 140 and the end plate 150 are partially integrally formed. In some other embodiments, the first panel 110, the second panel 120, the first side plate 130, the second side plate 140 and the end plate 150 can also be all integrally formed to improve the structural strength.

[0048] Furthermore, both the first panel 110 and the second panel 120 are integrally formed “匚”-shaped structures.

[0049] In the above embodiments, the one-piece molded "U"-shaped structure design significantly improves the overall geometric stiffness and resistance to torsional deformation of the panel through the closed frame shape, effectively preventing warping under assembly stress or external impact, thereby ensuring the stability and fitting accuracy of the panel dimensions. Secondly, the cavity structure of the "U"-shaped cross-section can provide excellent buffering and energy absorption effects without increasing the material thickness, enhancing the mechanical protection of internal components. In addition, the one-piece molding process eliminates splicing gaps, which not only simplifies the production process and reduces assembly costs, but also eliminates structural weaknesses caused by poor splicing, while ensuring the integrity and aesthetics of the appearance surface and avoiding the risk of dust accumulation or foreign objects entering the gaps.

[0050] Furthermore, the first panel 110, the second panel 120, the first side panel 130, and the second side panel 140 are all integrally formed.

[0051] In the above embodiments, the integrated molding design of the first panel 110, the second panel 120, the first side panel 130, and the second side panel 140 eliminates the seams and connection points commonly found in traditional splicing structures. This not only significantly improves the structural rigidity and torsional resistance of the overall frame, making it less prone to deformation or loosening when subjected to assembly stress or external impact, but also ensures assembly accuracy and long-term reliability. At the same time, this design simplifies the production process, reduces the use of fasteners or glue, lowers manufacturing costs and potential quality control risks, and achieves a seamless and smooth appearance, improving the product's aesthetics and dustproof and waterproof performance, and avoiding the problem of dust accumulation or corrosion in gaps.

[0052] Furthermore, such as Figure 4 , Figure 5 As shown, the shielding assembly 200 includes a shielding body 210, a first mounting portion 220, and a second mounting portion 230. The first mounting portion 220 and the second mounting portion 230 are disposed opposite to each other at both ends of the shielding body 210. The first mounting portion 220 is detachably connected to the first side plate 130, and the second mounting portion 230 is detachably connected to the second side plate 140. The shielding body 210 is disposed between the first panel 110 and the second panel 120, and extends at least partially out of the limiting hole 104.

[0053] In the above embodiments, this application designs the shielding assembly 200 as a modular integral structure consisting of a shielding body 210, a first mounting part 220, and a second mounting part 230. This achieves independent assembly and reliable fixation of the shielding function and the main frame 100, significantly improving the stability and maintainability of electromagnetic shielding. The first mounting part 220 and the second mounting part 230 are respectively disposed at both ends of the shielding body 210, forming symmetrically distributed connection fulcrums. This ensures that the shielding body 210 is subjected to uniform force during installation, avoiding warping, tilting, or poor contact caused by unilateral force. It also ensures that the shielding body 210, after extending out of the limiting hole 104, can maintain parallel contact with the upper and lower metal surfaces of the hard disk slot inner wall, forming a continuous, low-impedance electromagnetic shielding path. The shielding body 210 is disposed between the first panel 110 and the second panel 120, and its position is strictly limited by the two side panels to prevent lateral displacement during insertion, removal, or transportation. This ensures that the extended portion of the shielding body 210 is always aligned with the limiting hole 104, achieving precise exposure. The detachable connection between the first mounting part 220 and the first side plate 130, and between the second mounting part 230 and the second side plate 140, allows the shielding assembly 200 to be pre-installed, replaced, or repaired independently of the main frame 100 without disassembling the entire dummy module, reducing maintenance costs and time. It also allows for flexible adaptation of shielding assemblies 200 with different materials or elastic properties to different models, enhancing product platform capabilities. Since the shielding body 210 is only connected to the side plates through the mounting parts at both ends, with the middle part completely suspended within the mounting cavity 101 and not rigidly fixed to the panel or end plate 150, the extended portion of the shielding body 210 can freely and elastically deform when inserted into the hard drive slot. This adapts to the minute dimensional tolerances and surface unevenness of the chassis inner wall, ensuring stable and reliable contact pressure and avoiding contact failure caused by thermal expansion or assembly errors in traditional rigid shielding structures. This structural design eliminates the reliance on local deformation or adhesive fixing of the plastic body for shielding functionality. Instead, physical contact is achieved through the synergistic action of metal elastic elements and mechanical clips, greatly improving the consistency and long-term reliability of shielding performance. Meanwhile, this modular layout allows the manufacturing, electroplating, and testing of the shielding body 210 to be carried out independently, which is conducive to improving production yield and quality control accuracy, providing technical support for large-scale mass production, and ultimately achieving high-performance, maintainable, and scalable electromagnetic shielding functions without increasing the external size of the dummy module or affecting the insertion and removal feel, effectively solving the core problem of traditional dummy module shielding failure.

[0054] Furthermore, such as Figure 6 As shown, a first mounting hole 131 is provided on the first side plate 130. The first mounting hole 131 is located at one end of the first side plate 130 near the end plate 150. At least a portion of the first mounting part 220 is used to extend into the first mounting hole 131, such as... Figure 1 , Figure 2As shown, a second mounting hole 141 is provided on the second side plate 140. The second mounting hole 141 is provided at both ends of the second side plate 140 near the end plate 150. At least a portion of the second mounting part 230 is used to extend into the second mounting hole 141. At least a portion of the first mounting part 220 and the second mounting part 230 are bendably provided along the extending direction of the shielding body 210 so that the shielding assembly 200 is detachably connected to the main frame 100.

[0055] In the above embodiments, such as Figure 3 As shown, this application provides a first mounting hole 131 at one end of the first side plate 130 near the end plate 150, and a second mounting hole 141 at the corresponding position on the second side plate 140. The first mounting portion 220 and the second mounting portion 230 of the shielding assembly 200 extend at least partially into the corresponding mounting holes. Simultaneously, the two mounting portions are bendable along the extension direction of the shielding body 210. This achieves a purely mechanical, elastic, snap-fit, detachable connection between the shielding assembly 200 and the main frame 100 without the need for screws, clips, or adhesives, significantly improving assembly efficiency and structural reliability. This structure allows the shielding assembly 200 to be pushed axially into the mounting cavity 101 during installation. The first mounting portion 220 and the second mounting portion 230 slide smoothly into the mounting hole under elastic deformation. After being fully in place, they return to their original shape, forming axial limiting and circumferential locking. This prevents the shielding assembly 200 from loosening or shifting under vibration or thermal expansion and contraction conditions, ensuring that the shielding body 210 always stably extends out of the limiting hole 104 and remains in contact with the inner wall of the chassis. Because the mounting holes are located near the end of the end plate 150, directly corresponding to the elastic extension area of ​​the shielding body 210, the physical positions of the snap-fit ​​point and the shielding action point are highly coordinated, minimizing the lever arm effect and preventing bending or stress concentration of the shielding body 210 due to installation position misalignment, thus extending the fatigue life of the metal spring. The bendable design of the first mounting part 220 and the second mounting part 230 along the extension direction of the shielding body 210 gives them adaptive deformation capability during insertion, making them compatible with assembly tolerances and material manufacturing errors, reducing reliance on mold precision and assembly tooling, and improving production yield. This structure requires no additional fasteners, avoiding the cumbersome assembly, increased costs, and metal shavings contamination risks associated with traditional screw fixing, and also avoiding the aging and failure problems of adhesive bonding in high temperature or humid environments. At the same time, when the shielding component 200 wears out due to long-term use or needs to be replaced with a different specification of shielding material, only a slight external force is needed to bend the mounting part again, allowing it to easily detach from the mounting hole, achieving non-destructive disassembly and quick replacement, greatly improving server maintenance efficiency.

[0056] Furthermore, the hard drive tray also includes at least one first latching portion 300, which is disposed on the first side plate 130 and / or the second side plate 140. The inner wall of the hard drive slot is provided with at least one second latching portion corresponding to the at least one first latching portion 300. The hard drive tray is detachably connected to the server through the at least one first latching portion 300 and the at least one second latching portion.

[0057] In the above embodiments, this application achieves a tool-free, mechanically detachable locking connection between the hard drive bracket and the server chassis by providing at least one first latching portion 300 on the first side plate 130 and / or the second side plate 140, which cooperates with at least one corresponding second latching portion provided on the inner wall of the hard drive slot. This significantly improves the reliability of installation and the convenience of maintenance. The cooperation structure between the first latching portion 300 and the second latching portion allows the dummy module to automatically snap into position during insertion into the hard drive slot, forming a stable axial limit. This prevents loosening or accidental dislodgement due to transportation vibration, thermal expansion and contraction, or external pulling, ensuring that the shielding component 200 always maintains reliable contact with the inner wall of the chassis, and guaranteeing the continuous effectiveness of the electromagnetic shielding function. This connection method abandons the unreliable solutions that rely on friction or adhesive fixation in the past. Through a precisely designed snap-fit ​​structure, mechanical engagement is achieved, giving the dummy module a clear "sense of being in place" and "sense of locking" during insertion and removal, improving the operator experience and assembly accuracy. Since the first latching part 300 is located on the side plate, its alignment with the latching slot inside the hard drive slot is consistent with the insertion path of the dummy module, ensuring that the latching action and insertion / removal direction are coaxial, avoiding lateral stress, and preventing deformation of the main frame 100 or displacement of the shielding component 200. This structure requires no additional tools or screws; it can be locked by pushing it in with one hand, and can also be released by applying force when pulling it out. This greatly improves the installation and maintenance efficiency of servers in densely deployed data center scenarios, reducing maintenance manpower costs and downtime.

[0058] Furthermore, such as Figures 1 to 3 As shown, each first snap-fit ​​portion 300 includes an elastic element 310 and a snap-fit ​​element 320, and each second snap-fit ​​portion is a snap-fit ​​groove. The elastic element 310 is disposed at one end of the first side plate 130 and / or the second side plate 140 near the end plate 150. At least a portion of the elastic element 310 is bendably disposed along the length direction of the end plate 150. The snap-fit ​​element 320 is disposed on the side of the elastic element 310 away from the mounting cavity 101, and at least a portion of the snap-fit ​​element 320 extends toward the direction away from the mounting cavity 101.

[0059] In the above embodiments, this application provides a combination structure of elastic member 310 and snap-fit ​​member 320 in each first snap-fit ​​portion 300, so that the elastic member 310 is bendably disposed at the end of the first side plate 130 or the second side plate 140 near the end plate 150 along the length direction of the end plate 150, and the snap-fit ​​member 320 is fixed to the side of the elastic member 310 away from the mounting cavity 101 and extends outward, thereby realizing an efficient, stable and reusable mechanical locking function between the hard disk tray and the snap-fit ​​slot in the server hard disk slot. During the insertion of the dummy module, the snap-fit ​​component 320 first contacts the edge of the snap-fit ​​groove. Under pressure, the elastic component 310 undergoes controlled bending deformation, allowing the snap-fit ​​component 320 to smoothly pass through the groove. After full insertion, the elastic component 310 returns to its original shape, and the snap-fit ​​component 320 springs back into the snap-fit ​​groove, forming a stable axial lock. This effectively prevents the dummy module from loosening or retracting under transportation, vibration, or thermal cycling conditions, ensuring that the shielding assembly 200 maintains reliable contact with the inner wall of the chassis, guaranteeing the continuity and consistency of electromagnetic shielding performance. The elastic component 310 is positioned along the length of the end plate 150, with its deformation direction aligned with the insertion / extraction force direction, avoiding torsional stress, reducing structural fatigue risk, and extending service life. Simultaneously, the snap-fit ​​component 320 extends away from the mounting cavity 101, positioning its engagement point with the snap-fit ​​groove outside the dummy module, avoiding interference with the internal shielding assembly 200 or the slide structure, ensuring that each functional module operates independently without interference. This design requires no additional fasteners or tools; locking can be achieved simply by pushing it in with one hand. Removal requires only moderate pulling force to bend and release the elastic element 310, enabling quick and non-destructive disassembly and significantly improving server deployment and maintenance efficiency in high-density data center environments. The integrated structure of the latch 320 and the elastic element 310 can be molded from the same engineering plastic as the main frame 100, resulting in a simple and low-cost manufacturing process. Furthermore, structural optimization allows it to adapt to different sized latch slots, providing good versatility and mass production consistency. This latch structure achieves strong locking force while maintaining a balance between low insertion and low removal force, balancing operational comfort and safety. It avoids difficulties in insertion and removal or structural damage due to excessive latching force, and also prevents accidental detachment due to insufficient force.

[0060] Furthermore, each first snap-fit ​​portion 300 also includes an unlocking member 330, which is disposed on the side of the elastic member 310 near the mounting cavity 101. At least a portion of the unlocking member 330 extends toward the end plate 150 and protrudes from the mounting cavity 101. The unlocking member 330 is movably disposed along the length direction of the end plate 150 to drive at least a portion of the elastic member 310 to bend along the length direction of the end plate 150.

[0061] In the above embodiments, such as Figure 7As shown, this application adds an unlocking member 330 to each first latching portion 300. This unlocking member 330 is located on the side of the elastic member 310 near the mounting cavity 101, extending towards the end plate 150 and partially protruding outside the mounting cavity 101. This allows the unlocking member 330 to move along the length of the end plate 150 and simultaneously bend the elastic member 310, achieving tool-free, one-handed unlocking of the hard drive tray in the locked state. This structure allows maintenance personnel to unlock the hard drive tray without tools or additional operating space, simply by touching and moving the unlocking member 330 protruding from the mounting cavity 101 along the end plate 150 direction. This simultaneously drives the elastic member 310 to undergo controllable deformation, causing the latching member 320 to disengage from the latching slot, unlocking the device, and enabling rapid removal of the dummy module. This significantly improves the efficiency and security of maintaining or replacing dummy modules in high-density server racks. Because the unlocking component 330 and the elastic component 310 are directly linked in structure, and their movement direction is parallel to the insertion and removal path, the unlocking action is completely coaxial with the insertion direction. This avoids structural stress concentration or dummy module tilting and jamming caused by lateral force application, ensuring a smooth, reliable, and jam-free unlocking process. The unlocking component 330 extends out of the mounting cavity 101, exposing it to the visible operating area at the front of the dummy module. This allows the operator to perform an integrated "press-slide-pull out" operation without changing their grip posture, improving the human-machine interaction experience. This design does not add any extra parts. The unlocking component 330 can be integrally molded with the elastic component 310 and the snap-fit ​​component 320 in the same plastic part structure. The manufacturing process is simple and cost-controllable. Furthermore, because no additional openings or external wrench structures are required, the integrity of the dummy module's appearance and the continuity of electromagnetic shielding are maintained.

[0062] Furthermore, such as Figure 7 As shown, along the length of the end plate 150, the end plate 150, the first side plate 130, and the second side plate 140 are all spaced apart.

[0063] In the above embodiment, along the length of the end plate 150, the end plate 150 is spaced apart from the first side plate 130 and the second side plate 140, forming a gap structure between the end plate 150 and the two side plates. This gap not only provides sufficient longitudinal clearance space for the elastic extension of the shielding component 200, ensuring that the shielding body 210 can extend freely and fit against the inner wall of the chassis when inserted into the hard drive slot, avoiding shielding failure due to structural interference, but also ensures that the unlocking component 330 is not blocked by the side plate when sliding along the end plate 150, guaranteeing smooth operation of the unlocking mechanism. This gap design also effectively reduces the overall material usage and weight of the dummy module, improving the lightweight level of the structure. During assembly, it allows the side plate and end plate 150 to have slight relative displacement due to thermal expansion and contraction or mechanical stress, avoiding stress accumulation that could cause cracking or deformation of the plastic parts. In addition, the channel formed by the gap facilitates air circulation, assists in heat dissipation, and reduces the risk of material aging caused by internal heat accumulation during long-term operation of the dummy module. More importantly, this structure forms a force point for pulling out the housing when disassembling the hard drive tray, i.e., a handle. When removing the hard drive tray, place your thumb and forefinger on both ends of the endplate for easier removal.

[0064] Furthermore, the main frame 100 also includes at least one first guide member 160, and at least one second guide member is provided on the hard disk slot corresponding to at least one first guide member 160. At least one of the first guide members 160 is provided on the side wall of the first side plate 130 and / or the second side plate 140 away from the mounting cavity 101. Each first guide member 160 extends along the extension direction of the first side plate 130 or the second side plate 140.

[0065] In the above embodiments, this application achieves precise, stable, and low-friction guidance between the hard drive bracket and the chassis slot during insertion by providing at least one first guide 160 extending longitudinally along the side plate extension direction on the side wall of the first side plate 130 and / or the second side plate 140 away from the mounting cavity 101, and providing a matching second guide at a corresponding position on the inner wall of the hard drive slot. This structure subjectes the dummy module to symmetrical longitudinal guidance constraints on both sides along the insertion path, effectively preventing offset, tilting, or jamming caused by assembly deviations, lateral forces, or vibrations, ensuring that the dummy module always slides smoothly along the predetermined axis, and improving the smoothness and consistency of the insertion and removal operation; the first guide 160 is continuously provided along the side plate extension direction, so that it continues to play a role throughout the entire insertion and removal stroke, avoiding the risk of failure of traditional point guidance in long strokes, and ensuring the stability of the dummy module's posture throughout the movement, especially in high-density server multi-module parallel insertion and removal scenarios, significantly reducing the risk of misinsertion, misalignment, or scratching of the slot. Because the guide component is located on the outer wall of the side plate, its position avoids the movement areas of the shielding component 200, the snap-fit ​​structure, and the unlocking mechanism, achieving zero interference between functional modules and ensuring independent and reliable operation of each mechanism; the guide structure adopts a sliding fit form, which does not rely on elastic deformation or mechanical engagement, reducing wear and abnormal noise, and improving long-term durability; at the same time, the fit clearance between the guide component and the guide groove can be precisely controlled, ensuring smooth sliding while limiting lateral sway, and enhancing the positioning accuracy of the dummy module in the unlocked state; this design does not require additional guide rails or metal sliders, and is achieved solely through integral molding of plastic parts, resulting in a simple structure, low cost, and ease of mass production.

[0066] Furthermore, the main frame 100 also includes at least one stop member 170. At least one of the first panel 110, the second panel 120, the first side panel 130 and the second side panel 140 is provided with at least one of the stop members 170. The at least one stop member 170 is provided at one end of the main frame 100 away from the hard disk slot. Each stop member 170 extends in a direction away from the end plate 150. When the hard disk tray is inserted into the hard disk slot, the stop member 170 abuts against the server housing.

[0067] In the above embodiments, this application provides at least one stop member 170 extending in a direction away from the end plate 150 at the end of the main frame 100 away from the hard drive slot, and integrates the stop member 170 onto at least one of the first panel 110, the second panel 120, the first side plate 130, or the second side plate 140. This achieves a precise axial limiting function for the hard drive bracket after it is inserted into the hard drive slot, ensuring that the dummy module is always limited to a preset installation depth. This prevents the shielding component 200 from being deformed under pressure, the snap-fit ​​structure from being misaligned, or the unlocking mechanism from failing due to over-insertion, thus ensuring the stable performance of electromagnetic shielding and mechanical locking. The outward-extending structural design of the stop member 170 allows it to directly form a rigid abutment with the inner wall or structural baffle of the server housing after the dummy module is fully inserted, forming a clear physical endpoint. This provides the operator with clear feedback on the insertion position, improving assembly accuracy and operational consistency, and avoiding under-installation or over-installation due to visual judgment errors. This structure does not rely on external limiting grooves or screws for fixation; the limiting is achieved entirely by the dummy module's own structure, simplifying the chassis design and reducing manufacturing costs. Furthermore, the stop component 170 is integrally molded with the main frame 100, eliminating the need for additional parts and improving structural integration and production yield. Since the stop component 170 is located at the rear of the dummy module, it forms a coordinated positioning system with the front-end snap-fit ​​structure and shielding component 200, constraining axial displacement and indirectly suppressing the dummy module's forward and backward movement under vibration, thus improving overall structural rigidity and impact resistance. Simultaneously, the extension direction of the stop component 170 is consistent with the insertion and removal direction, avoiding the introduction of lateral stress and preventing the main frame 100 from warping or cracking due to uneven stress. During maintenance and replacement, the contact surface of the stop component 170 can serve as a reference point for pulling out the module, making it easier for maintenance personnel to apply a uniform pulling force and avoiding structural damage caused by localized stress.

[0068] Furthermore, the main frame 100 also includes at least one reinforcing member 180, and at least one heat dissipation groove 103 is provided on the first panel and / or the second panel, with the groove opening of the heat dissipation groove 103 facing the side away from the end plate.

[0069] In the above embodiments, this application provides at least one heat dissipation slot 103 on the first panel 110 and / or the second panel 120, with the slot opening of the heat dissipation slot 103 facing away from the end plate 150. Combined with the addition of at least one reinforcing member 180 on the panel, this effectively improves the heat dissipation performance and thermal stability of the hard drive tray without weakening the structural strength of the main frame 100. The open orientation design of the heat dissipation slot 103 allows the rear end of the dummy module to form a direct heat exchange channel with the internal airflow of the chassis after it is inserted into the server chassis. This allows hot air to flow backward along the slot opening, promoting natural convection heat dissipation of the dummy module body and surrounding components, reducing local temperature rise caused by long-term operation, preventing deformation, aging, or stress cracking of plastic parts due to heat accumulation, and extending the product's service life. The reinforcement 180 is located around the heat dissipation slot 103 or in the stress concentration area of ​​the panel to compensate for the stiffness loss caused by the slotting, significantly improve the panel's bending and torsional resistance, prevent the dummy module from deforming during transportation, insertion or removal or vibration, and ensure the accurate positioning and long-term stable operation of key functional structures such as the snap-fit ​​component 320, guide component, and shielding component 200.

[0070] Furthermore, at least one reinforcing member 180 is provided on the first panel 110 and / or the second panel 120. Each reinforcing member 180 is provided on the side of the heat dissipation groove 103 near the groove opening, and the two ends of the reinforcing member 180 are respectively connected to the two sides of the heat dissipation groove 103.

[0071] In the above embodiments, this application provides a reinforcing member 180 on the side of each heat dissipation groove 103 near the groove opening on the first panel 110 and / or the second panel 120, and directly connects the two ends of the reinforcing member 180 to the two side walls of the heat dissipation groove 103 to form a closed support structure around the groove opening, which significantly improves the structural rigidity and deformation resistance of the heat dissipation groove 103 area. This design effectively disperses localized concentrated stress caused by insertion and extraction forces, vibration loads, or thermal stress without increasing the total amount of material, preventing the edges of the main frame 100 from warping, tearing, or collapsing during long-term use. At the same time, this structure forms a rigid annular support around the groove opening, suppressing the tendency of the panel to sink into the groove when under force, and avoiding displacement of the shielding component 200 or the snap-fit ​​structure due to panel deformation, thereby maintaining the reliability of electromagnetic shielding contact and the accuracy of mechanical locking. The direct connection between the two ends of the reinforcing member 180 and the sidewall of the heat dissipation slot 103 allows the load to be evenly transferred to the main frame 100 along the length of the slot, avoiding stress concentration at a single point and significantly improving the overall bending and torsional resistance of the panel. Especially in high-density deployment environments, it effectively prevents chain deformation caused by assembly compression between adjacent modules. This structure adopts a one-piece molding process, requiring no additional fasteners or welding, making manufacturing simple and cost-effective. Furthermore, the contour of the reinforcing member 180 precisely matches the shape of the heat dissipation slot 103, without occupying extra space or affecting the external dimensions and plug-in compatibility of the dummy module. At the same time, since the reinforcing member 180 is located inside the slot, it does not affect the flow path of external airflow through the slot, ensuring that the heat dissipation efficiency is not affected by the structural reinforcement, achieving dual optimization of "structural reinforcement" and "heat dissipation performance".

[0072] Furthermore, such as Figures 1 to 3 As shown, the reinforcing member 180 is a reinforcing rib, which is set at the opening of the heat dissipation groove 103. The reinforcing rib extends along the extension direction of the groove opening, and the length of the reinforcing rib along the extension direction of the groove opening is m, where 53mm≤m≤70mm; the length of the reinforcing rib along the depth direction of the heat dissipation groove 103 is n, where 6mm≤n≤15mm; the thickness of the reinforcing rib is equal to the thickness of the first panel 110 or the second panel 120.

[0073] In the above embodiments, this application designs the reinforcing member 180 as a reinforcing rib extending along the opening of the heat dissipation groove 103, and limits its length m along the groove opening direction to 53mm to 70mm and its length n along the groove depth direction to 6mm to 15mm, and makes the thickness of the reinforcing rib consistent with the thickness of the first panel 110 or the second panel 120, thereby achieving high-efficiency and low-disturbance rigid reinforcement of the edge of the heat dissipation groove 103 under the premise of precisely controlling the range of structural reinforcement. This size range has been mechanically verified to effectively cover the main stress areas of the dummy module during insertion and removal, ensuring that the slot remains flat and undeformed under repeated mechanical loads. This prevents localized collapse from affecting the smooth flow of heat dissipation airflow or causing contact failure of the shielding springs. The length of the reinforcing rib matches the length of the heat dissipation slot 103, ensuring uniform stress distribution along the slot length and preventing stress concentration at the ends that could lead to cracks, thus improving long-term durability. The reinforcing rib length n is in the range of 6mm to 15mm, providing sufficient bending section modulus to resist panel bending deformation while avoiding excessive structural interference with internal components or increased material costs, achieving both strength and lightweight design. The optimal balance is achieved; the thickness of the reinforcing ribs is consistent with that of the panel body, ensuring uniform melt flow and consistent cooling shrinkage during molding, avoiding injection molding defects such as shrinkage marks and warping due to differences in wall thickness, and improving manufacturing yield and dimensional stability; the integrated structure makes the reinforcing ribs and the base body form a continuous load transfer path, eliminating the risk of interface slippage or loosening, significantly improving structural reliability, while eliminating assembly processes, reducing labor costs and failure points, and is suitable for highly automated, mass production scenarios; this design precisely strengthens the most deformable areas without adding extra parts or changing the outline, so that the heat sink 103 maintains structural rigidity while having ventilation function.

[0074] In some embodiments, the reinforcing member 180 is detachably connected to the first panel 110 and / or the second panel 120. By making the reinforcing member 180 detachably connected to the first panel 110 and / or the second panel 120, this application achieves modular reinforcement and flexible maintenance of the structural strength of the heat sink 103 area without changing the overall structure of the main frame 100. This design allows the reinforcing member 180 to be replaced independently during manufacturing, transportation, or use in case of accidental damage, aging, or specification changes, without scrapping the entire main frame 100, significantly reducing maintenance costs and spare parts inventory complexity. Simultaneously, the detachable structure allows the reinforcing member 180 to be selected or upgraded according to the heat dissipation requirements or mechanical load conditions of different server chassis. For example, a reinforcing member 180 made of higher strength materials can be used in high-vibration environments, or a thinner specification can be used in lightweight scenarios, improving the platform adaptability and design flexibility of the dummy module. Because the reinforcing member 180 is formed independently of the main body, it simplifies... The injection molding process of the main frame 100 has been streamlined to avoid uneven injection filling, shrinkage cavities, or internal stress concentration caused by local thickening or complex rib structures, thereby improving the yield rate of the main components. In the assembly process, the reinforcing component 180 can be installed later, which facilitates external reinforcement after the internal components such as the shielding component 200 and the snap-fit ​​structure are pre-assembled, improving the rationality of the overall assembly sequence and work efficiency. The detachable connection method, such as the snap-fit, screw, or plug-in structure, does not damage the integrity of the main panel and ensures that the airflow channel at the edge of the heat sink 103 is not affected by welding or adhesive processes, maintaining the continuity of electromagnetic shielding performance.

[0075] like Figure 8 As shown, this application also provides a server, including the above-mentioned hard disk bracket. The server includes a housing 400 and a plurality of hard disk slots, all of which are disposed on the housing. The hard disk bracket is used to be inserted into one of the plurality of hard disk slots.

[0076] In the above embodiments, the server provided in this application achieves a holistic improvement in the electromagnetic compatibility performance and a unified optimization of the structural integrity of the entire system by setting multiple hard drive slots on the casing and inserting the aforementioned hard drive bracket into at least one slot without a real hard drive installed. Since the hard drive bracket has an independent shielding component 200, whose shielding body 210 extends through the limiting hole 104 and forms elastic contact with the inner wall of the hard drive slot, each empty slot with a dummy module installed no longer becomes an opening for electromagnetic radiation leakage, but is transformed into a continuous shielding extension section at the same potential as the metal casing of the chassis. This eliminates the electromagnetic shielding breakpoints caused by empty slots in traditional servers, significantly reduces external radiation interference, enhances the system's resistance to external electromagnetic interference, and ensures that the system can still meet electromagnetic compatibility certification standards under high-density, high-frequency operating environments. This server does not require a separate built-in shielding structure or additional metal baffles for each empty slot; unified shielding of all slots can be achieved simply through standardized, detachable hard drive brackets, greatly simplifying the internal structural design and manufacturing process of the chassis, and reducing the types of materials and assembly complexity. Meanwhile, due to the tool-free plug-and-play feature of the dummy modules, maintenance personnel can quickly replace or add dummy modules without interrupting system operation or disassembling other components, adapting to different storage configuration needs and improving the flexibility of server deployment and maintenance. Furthermore, all hard drive slots maintain consistency in appearance, size, and mechanical interface, presenting a unified front-window visual effect regardless of whether hard drives or dummy modules are installed, enhancing the product's industrial design quality and professionalism. This structure effectively avoids airflow turbulence and uneven heat dissipation problems caused by missing slots, ensuring continuous and stable airflow within the chassis and contributing to improved overall heat dissipation efficiency. By integrating shielding functionality into the universal dummy modules, server manufacturers can flexibly configure full, half-full, or sparse storage solutions on a single platform without developing dedicated shielding solutions for different configurations, significantly reducing R&D and supply chain costs.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this application.
