Description

Technical Field

[0001] This application relates to the field of server hard disk technology, and in particular to a hard disk mounting device, hard disk assembly, and electronic device. Background Technology

[0002] M.2 is an interface standard primarily used for storage devices such as solid-state drives (SSDs) and expansion devices such as wireless network cards. M.2 interfaces come in various sizes, with common types including 2280 and 22110. The "22" indicates a width of 22 millimeters, and the following numbers indicate the length. Different M.2 lengths are suitable for different application scenarios and device space requirements.

[0003] However, in related technologies, each M.2 of different lengths requires either a bracket of a different size for fixation, or the position of the fasteners needs to be changed when replacing M.2s of different lengths. This makes it difficult to perform a unified installation operation during deployment and assembly, and the installation process is complicated. Utility Model Content

[0033] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0034] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0035] Example 1

[0036] This application provides a hard disk fixing device, such as... Figures 1 to 6 As shown, it includes: a bracket 1, which includes a first end 101 and a second end 102 disposed opposite to each other along its length; and an adapter 2, which has a first elastic snap-fit ​​portion 201 and a second elastic snap-fit ​​portion 202. The bracket 1 and the adapter 2 have two states: connected and separated. In the separated state, the first end 101 of the bracket 1 is used to snap onto one end of the first module 10, and the second end 102 is used to snap onto the other end of the first module 10. In the connected state, the first end 101 of the bracket 1 snaps onto the first elastic snap-fit ​​portion 201, the second elastic snap-fit ​​portion 202 snaps onto one end of the second module 20, and the second end 102 of the bracket 1 snaps onto the other end of the second module 20. The second module 20 has a different length from the first module 10.

[0037] The bracket 1 can be made of metal or high-strength plastic, and is generally elongated, having a first end 101 and a second end 102 arranged opposite to each other along its length. The bracket 1 is used to directly accommodate and fix at least one standard-sized hard disk module. Its first end 101 and second end 102 are provided with snap-fit ​​structures, such as flat sidewalls, buckles, grooves, or elastic arms, which can directly snap the two ends of the hard disk module of that size, achieving a stable fixation.

[0038] The adapter 2 is a separate component that can be connected to or detached from the bracket 1. The adapter 2 has a first elastic locking part 201 and a second elastic locking part 202. The first elastic locking part 201 is used to lock into the first end 101 of the bracket 1. The second elastic locking part 202 is used to lock into one end of a hard drive module of a different size. The locking parts can be made of elastic materials such as metal plates or engineering plastics, and can deform to achieve locking and releasing.

[0039] The adapter 2 and the bracket 1 have both a detached and a connected state. For example, when the adapter 2 is removed from the bracket 1, they are in a detached state. Then, the longer first module 10 can be placed into the bracket 1. The first end 101 of the bracket 1 directly engages with one end of the first module 10, and the second end 102 of the bracket 1 directly engages with the other end. At this time, the bracket 1 acts as an independent fixing device, firmly holding the longer first module 10. Alternatively, the first elastic engaging part 201 of the adapter 2 can be engaged with the first end 101 of the bracket 1, and they are in a connected state. Then, the shorter second module 20 is placed into the assembled device. The second elastic engaging part 202 of the adapter 2 engages with one end of the second module 20, and the second end 102 of the bracket 1 engages with the other end of the second module 20. Since the adapter 2 occupies the space at one end of the bracket 1, it effectively shortens the usable length inside the bracket 1, thus perfectly adapting to the shorter second module 20.

[0040] The first module 10 and the second module 20 are solid-state drives (SSDs) of two different lengths, such as the common 2280 (80mm long) and 22110 (110mm long) sizes. The size of the adapter 2 can be customized according to the specific length of the second module 20. If it is necessary to support multiple different lengths of the second module 20 (e.g., simultaneously supporting multiple short SSDs such as 2230, 2242, 2260, and 2280), multiple adapters 2 of corresponding sizes can be pre-made. By setting the adapter 2, users can flexibly select the matching adapter 2 according to the type of SSD installed when using the same standard-sized bracket 1.

[0041] The hard drive mounting device provided in this application embodiment uses a universal bracket 1 and a detachable adapter 2 to secure two or more hard drive modules of different sizes, thereby improving the versatility and flexibility of the hard drive. Manufacturers only need to produce one standard bracket 1 and a small number of low-cost adapters 2 to meet the installation needs of various hard drives, effectively reducing the types of components, simplifying production complexity, and lowering overall costs. Furthermore, for end users or maintenance personnel, the flexible snap-fit ​​structure connects the adapter 2 to the bracket 1 and the hard drive, allowing the bracket 1 to be permanently or semi-permanently installed in the motherboard or equipment chassis, eliminating the need to repeatedly disassemble the bracket 1 when replacing hard drives of different sizes. Maintenance personnel only need to replace the adapter 2 according to the hard drive size; the conversion process requires no tools, and the installation and removal of the adapter 2 can be completed simply by manual pressing, greatly simplifying the installation process and improving the convenience of equipment maintenance and upgrades.

[0042] In some embodiments, such as Figure 2 and Figure 4 As shown, the bracket 1 has a base plate 103, which is used to support the first module 10 or the second module 20; the first elastic snap-fit ​​part 201 includes a first elastic snap hook structure 201a and a first rigid snap hook structure 201b; the base plate 103 is provided with a first snap-fit ​​hole 103a and a second snap-fit ​​hole 103b along the length direction near the first end 101, and the distance between the first elastic snap hook structure 201a and the first rigid snap hook structure 201b is adapted to the distance between the first snap hook hole 103a and the second snap hook hole 103b; the first elastic snap hook structure 201a passes through the first snap hook hole 103a and snaps with the base plate 103, and the first rigid snap hook structure 201b passes through the second snap hook hole 103b and snaps with the base plate 103.

[0043] The bracket 1 includes a base plate 103 for supporting the first module 10 or the second module 20. Near its first end 101, the base plate 103 has two spaced-apart snap-fit ​​holes along its length, namely a first snap-fit ​​hole 103a and a second snap-fit ​​hole 103b. The first snap-fit ​​hole 103a and the second snap-fit ​​hole 103b penetrate the base plate 103. The snap-fit ​​holes can be rectangular, circular, irregular, or other shapes.

[0044] The first elastic latching part 201 on the adapter 2 consists of two latching structures with different characteristics. For example, the first elastic latching structure 201a can be elastic and deformable. Through its elastic deformation, the first elastic latching structure 201a can not only reduce the accuracy requirements of hole alignment and facilitate quick installation, but also adapt to slight vibrations or displacements to ensure reliable latching of the adapter 2 under repeated insertion and removal or vibration. The first rigid latching structure 201b can be a rigid or semi-rigid structure, which is not easily deformed and can be used to provide positioning and anti-dislodgement functions. The spacing between these two latching structures on the adapter 2 is precisely matched with the distance between the first latching hole 103a and the second latching hole 103b on the base plate 103 of the bracket 1. The latching structure can be L-shaped, Z-shaped, or other shapes.

[0045] When it is necessary to connect the adapter 2 to the bracket 1, the first elastic hook structure 201a and the first rigid hook structure 201b of the adapter 2 are aligned with the first locking hole 103a and the second locking hole 103b on the base plate 103 of the bracket 1, respectively. The rigid first locking hook structure 201b is first inserted into the second locking hole 103b. Because it is a rigid structure, it can effectively restrict the movement of the adapter 2 in the length direction of the bracket 1, and play a role in positioning and fixing. Subsequently, pressure can be applied to the first elastic hook structure 201a. Under the action of pressure, the first elastic hook structure 201a undergoes elastic deformation and passes through the first locking hole 103a. After it passes through the first locking hole 103a, it returns to its original shape by its own elasticity and can be locked under or inside the base plate 103, forming a locking force to prevent the adapter 2 from accidentally loosening. During disassembly, simply press or flick the release mechanism provided at the end of the first elastic hook structure 201a with your finger, such as the lever or pressing part connected to the first elastic hook structure 201a, to deform it and remove it from the first snap-fit ​​hole 103a, thereby removing the adapter 2 from the bracket 1 so that the two are in a separated state, and then the longer first module 10 can be placed into the bracket 1.

[0046] By precisely matching the spacing between the first elastic hook structure 201a and the first rigid hook structure 201b with the spacing between the two locking holes on the bracket 1, not only is the displacement of the adapter 2 in the length direction of the bracket 1 restricted, but also precise guidance and positioning are achieved. The elastic hook provides pre-tightening force and anti-dislodgement function to ensure reliable connection, while the rigid hook provides stable positioning and anti-shaking capability. The two work together to ensure a secure connection while still allowing for convenient manual installation and removal, effectively preventing the hard drive from loosening due to vibration or impact during operation.

[0047] In some embodiments, such as Figure 3As shown, the adapter 2 also has a release structure 203, which is connected to the first elastic hook structure 201a. When the release structure 203 is subjected to external force, it can push the first elastic hook structure 201a to deform so as to separate from the first snap hole 103a.

[0048] The release structure 203 is disposed on the adapter 2 and connected to the first elastic hook structure 201a. Its position can be set in an area easily accessible to the user's fingers, such as the side or top of the adapter 2, forming a clear pressing area or toggle area for easy operation.

[0049] The unlocking structure 203 can take various design forms. For example, the unlocking structure 203 can be a protruding paddle or lever extending from the top or side of the first elastic hook structure 201a; or it can be a sliding push button that can cause the first elastic hook structure 201a to deform when pushed. The specific structure is not limited.

[0050] In the connected state, the adapter 2 is engaged with the base plate 103 of the bracket 1 via the first elastic latch structure 201a and the first rigid latch structure 201b. When it is necessary to disassemble the adapter 2, the user presses or flicks the release structure 203 with their finger. The applied external force is transmitted through the release structure 203 to the first elastic latch structure 201a connected to it, forcing it to undergo elastic deformation in a direction away from the base plate 103.

[0051] When the first elastic hook structure 201a deforms sufficiently under the push of the release structure 203, its hook-shaped portion will disengage from the first locking hole 103a of the bracket 1 base plate 103, thereby releasing the main locking force. At this time, the adapter 2 is only positioned in the second locking hole 103b by the first rigid hook structure 201b and is no longer locked. The user can easily pull out the entire adapter 2, causing the first rigid hook structure 201b to disengage from the second locking hole 103b, thus completing the disassembly.

[0052] By designing the release mechanism 203, an ergonomically defined point of force is provided, making disassembly easy, simple, and intuitive. A simple finger press or flick allows for quick unlocking, significantly improving the efficiency and convenience of disassembly.

[0053] In some embodiments, such as Figure 3As shown, the second elastic latching part 202 includes a second elastic latching structure 202a and a first support plate 202b. The second elastic latching structure 202a is disposed on the first support plate 202b, and the side of the second elastic latching structure 202a facing away from the first support plate 202b is an arc surface. When the second module 20 is subjected to an external force, one end of the second module 20 can be squeezed along the arc surface and the second elastic latching part 202 undergoes elastic deformation, so that the second module 20 can be latched between the second elastic latching structure 202a and the first support plate 202b.

[0054] The first support plate 202b can be a horizontally arranged plate-like or block-like structure, serving as a reference surface for the second module 20 and the second elastic snap-fit ​​part 202 to snap together, providing stable support for the second module 20. The second elastic snap-fit ​​structure 202a is arranged opposite to the first support plate 202b, and together they form a slot for accommodating the end of the second module 20. The side of the second elastic snap-fit ​​structure 202a facing the insertion direction of the second module 20 and away from the first support plate 202b is set as an arc surface, which can play a guiding role during installation.

[0055] During the installation of the second module 20, one end of the second module 20 can be aligned and placed into the slot entrance formed by the first support plate 202b and the second elastic hook structure 202a. When the user pushes the second module 20 into the bracket 1, the edge of the second module 20 first contacts the arc surface of the second elastic hook structure 202a. As the second module 20 continues to advance, its edge slides along the arc surface and gradually applies pressure to the second elastic hook structure 202a. Under the action of the pushing force, the second elastic hook structure 202a undergoes elastic deformation, increasing the distance between it and the first support plate 202b, creating space for the second module 20 to engage. When the second module 20 is fully pushed into place, the second elastic hook structure 202a rebounds under its own elastic restoring force, and its hook part re-locks the end of the second module 20, clamping the second module 20 between the second elastic hook structure 202a and the first support plate 202b, completing the installation. During disassembly, the user only needs to pull the second module 20 outward. The edge of the second module 20 will squeeze the inner side of the second elastic hook structure 202a, causing it to undergo elastic deformation again, thereby disengaging from the slot and achieving quick disassembly.

[0056] By using the arc surface on the second elastic hook structure 202a as a guide slope, the resistance during insertion of the second module 20 can be significantly reduced. The user only needs to align the second module 20 and press it along a straight line; the guiding characteristics of the arc surface allow the second module 20 to automatically trigger the deformation of the hook. The entire installation process requires no additional operation, making it simple and efficient. Simultaneously, the clamping structure formed by the second elastic hook structure 202a and the first support plate 202b applies clamping force to the end of the second module 20, ensuring a stable connection and preventing the second module 20 from loosening or experiencing poor contact.

[0057] In some embodiments, such as Figure 3 As shown, the adapter 2 also has a prying structure 204, which includes a prying end 204a and a force-applying end 204b. The force-applying end 204b is used to bear the force and has a first position and a second position under the force. In the first position, the prying end 204a and the first support plate 202b are located on the same horizontal plane in the same straight direction. In the second position, the prying end 204a is raised relative to the first support plate 202b toward the second elastic hook structure 202a to push the second module 20 out from between the second elastic hook and the first support plate 202b.

[0058] The prying structure 204 is mounted on the adapter 2 and can be integrally injection molded with the main body of the adapter 2. It includes a prying end 204a and a force-applying end 204b. The force-applying end 204b is located at one end of the prying structure 204, exposed outside the adapter 2, facilitating user finger pressing or operation, and is used to bear external forces (such as finger pressure). The prying end 204a is located at the other end of the prying structure 204, near the first support plate 202b, and can be used to abut against the bottom or edge of the second module 20, providing an upward pushing force. The prying structure 204 can rotate around its central part or a fixed fulcrum, realizing the linkage between the force-applying end 204b and the prying end 204a.

[0059] The prying structure 204 has two working states under external force. When the second module 20 does not need to be disassembled, the force-applying end 204b is not pressed and is in the first position. At this time, the prying end 204a and the first support plate 202b are located on the same horizontal plane in the same straight direction, which ensures that when installing the second module 20, the prying end 204a will not protrude or obstruct the second module 20 from entering the slot, and will not affect normal installation. At the same time, the prying end 204a can also work with the first support plate 202b to provide stable bottom support for the second module 20.

[0060] When the second module 20 needs to be disassembled, the user presses down on the force-applying end 204b with their finger, moving it from the first position to the second position. According to the lever principle, the downward pressure of the force-applying end 204b is converted into an upward tilting motion of the prying end 204a. The raised prying end 204a then presses against the bottom of the second module 20, applying an upward force to push the second module 20 out of the slot formed by the second elastic hook structure 202a and the first support plate 202b, thus releasing the locking state.

[0061] By incorporating the prying structure 204, users can automatically eject the second module 20 without having to manually pry or maneuver its edges. Simply pressing the force-applying end 204b completes the ejection process. This simple and labor-saving operation significantly improves maintenance efficiency, making it particularly suitable for scenarios where space is limited or operation is inconvenient.

[0062] In some embodiments, the prying structure 204 further includes a lever 204c, with a force-applying end 204b and a prying end 204a respectively disposed at both ends of the lever 204c, and the force-applying end 204b being disposed closer to the first end 101 relative to the prying end 204a; the prying end 204a includes a plurality of second support plates, which are respectively disposed opposite to each other on both sides of the first support plate 202b.

[0063] The prying structure 204 includes a lever 204c, which serves as the main body of the prying structure 204. The lever 204c can be a rigid rod-shaped or plate-shaped component that can rotate about its fulcrum (such as a pivot or elastic hinge point). The force-applying end 204b and the prying end 204a are located at opposite ends of the lever 204c. The force-applying end 204b is closer to the first end 101 of the bracket 1 than the prying end 204a. This allows the user's pressing point to be located on one side of the adapter 2, avoiding direct pressure on the second module 20 during disassembly and preventing damage to the second module 20 or the connector. According to the lever principle, a small pressing force applied by the user to the force-applying end 204b can generate a larger lifting force at the prying end 204a, achieving effortless operation.

[0064] The prying end 204a includes multiple second support plates (e.g., two or four), which are symmetrically arranged on both sides of the first support plate 202b and remain parallel to or on the same plane as the first support plate 202b. When the force-applying end 204b is not pressed, the lever 204c is in its initial position, and the multiple second support plates and the first support plate 202b together form a flat and continuous support surface, providing uniform and stable support for the bottom of the second module 20. When the second module 20 needs to be disassembled, the user presses down on the force-applying end 204b near the first end 101, and the lever 204c rotates around the fulcrum, causing the prying end 204a to tilt upward. Since the multiple second support plates are integrated into the prying end 204a, they can be lifted synchronously, applying an upward force from both sides of the bottom of the second module 20 simultaneously.

[0065] By setting multiple second support plates on both sides of the first support plate 202b, simultaneous ejection at two or more points is achieved. This ensures that the second module 20 is evenly lifted, allowing its end to smoothly disengage from the latch of the second elastic hook structure 202a, thus achieving a stable and non-skewed ejection operation.

[0066] In some embodiments, such as Figures 2 to 4 As shown, the adapter 2 also includes a plurality of second rigid hook structures 205, and the base plate 103 is provided with a plurality of openings 103c. One second rigid hook structure 205 can pass through one opening 103c to engage with the base plate 103. The second rigid hook structure 205 is used to limit the displacement of the adapter 2 relative to the bracket 1.

[0067] The adapter 2 is provided with a plurality of second rigid latch structures 205 (e.g., two or more). For example, a pair of latches are provided opposite each other in the width direction of the adapter 2, and / or a pair of latches are provided at one end in the length direction. The latches may be made of rigid or semi-rigid materials (such as metal or high-strength plastic) that are not easily deformed.

[0068] On the base plate 103 of the bracket 1, in addition to the snap-fit ​​holes for the first elastic snap hook and the first rigid snap hook to pass through, multiple openings 103c can be pre-formed by stamping or injection molding. The shape, size, and position of the openings 103c correspond to the second rigid snap hook structures 205 on the adapter 2. Each second rigid snap hook structure 205 can be inserted into one opening 103c, and after being fully inserted, its snap hook portion forms a mechanical limit with the edge of the opening 103c.

[0069] During installation, the first elastic hook and the first rigid hook on the adapter 2 are aligned with their corresponding locking holes. Simultaneously, multiple second rigid hook structures 205 are also aligned and inserted into their dedicated openings 103c. The first elastic hook provides locking force upon rebound, while all other rigid hooks engage with the edge of the opening 103c on the base plate 103, forming a multi-point limiting mechanism. This effectively restricts the displacement of the adapter 2 relative to the bracket 1 in length, width, and vertical directions, comprehensively constraining the degrees of freedom of the adapter 2, ensuring accurate positioning and secure fixation after installation, and preventing the second module 20 from loosening due to equipment vibration or external forces.

[0070] In some embodiments, the adapter 2 may be made of a high-strength plastic material, such as engineering plastics (nylon (PA) or polyamide (PBT)) with a tensile strength of 50MPa-150MPa. The specific strength of the material is not limited, as long as it meets the strength and elasticity requirements of the elastic functional components on the adapter 2, such as the first elastic snap-fit ​​part 201, the unlocking structure 203, and the pry-up structure 204, while also ensuring the structural integrity and strength of the adapter 2 after injection molding. All functional components of the adapter 2, including the first elastic snap-fit ​​part 201, the second elastic snap-fit ​​part 202, the unlocking structure 203, the pry-up structure 204, and the second rigid hook structure 205, can be injection molded in one piece in a single mold, forming a complete, seamless single component. This not only meets the performance requirements of the adapter 2 in terms of strength, elasticity, and durability, but also significantly improves production efficiency and product consistency.

[0071] In some embodiments, the bracket 1 includes a metal housing 104 and an insulating housing 105. The insulating housing 105 is disposed at the second end 102 of the bracket 1, and the metal housing 104 is snapped into the insulating housing 105.

[0072] The bracket 1 consists of two parts: a metal housing 104 and an insulating housing 105. The metal housing 104 forms the main body of the bracket 1 and includes the base plate 103, side walls, and first end 101. Its material can be conductive metals such as galvanized steel, copper, or aluminum alloy, possessing excellent mechanical strength and good thermal conductivity. This not only ensures the hard drive is securely installed but also effectively conducts the heat generated during hard drive operation, improving overall heat dissipation capacity and meeting the heat dissipation requirements of high-power hard drives. The insulating housing 105 is located at the second end 102 of the bracket 1 and can be an independent component made of insulating materials such as high-strength engineering plastics like PBT and PA.

[0073] The metal housing 104 and the insulating housing 105 can be securely connected via a snap-fit ​​structure (such as a snap-fit, slot, or elastic arm), eliminating the need for additional fasteners such as screws, making assembly simple and efficient. The specific snap-fit ​​structure is not limited, as long as it achieves a reliable and detachable connection.

[0074] In practical applications, after the hard drive module (whether it is the first module 10 or the second module 20) is installed into the bracket 1, its gold fingers or connectors will extend from the second end 102 of the bracket 1 and mate with the corresponding connectors on the motherboard. Since the insulating shell 105 is located at the second end 102, it directly surrounds and supports the end area of ​​the hard drive circuit board, effectively isolating the exposed conductive lines from the metal shell 104 and avoiding the risk of short circuits caused by the metal bracket 1 contacting the circuit.

[0075] Example 2

[0076] A second aspect of this application provides a hard disk assembly, such as... Figure 7 As shown, it includes: a first module 10 or a second module 20, the first module 10 and the second module 20 having different lengths; a hard disk mounting device 30, including a bracket 1, the bracket 1 including a first end 101 and a second end 102 arranged opposite to each other along its length direction; an adapter 2, the adapter 2 having a first elastic snap-fit ​​portion 201 and a second elastic snap-fit ​​portion 202, the bracket 1 and the adapter 2 having two states: connected and separated; in the separated state, the first end 101 of the bracket 1 is used to snap onto one end of the first module 10, and the second end 102 is used to snap onto the other end of the first module 10; in the connected state, the first end 101 of the bracket 1 snaps onto the first elastic snap-fit ​​portion 201, the second elastic snap-fit ​​portion 202 is used to snap onto one end of the second module 20, and the second end 102 of the bracket 1 is used to snap onto the other end of the second module 20.

[0077] The hard disk assembly includes a hard disk fixing device 30 and a first module 10 or a second module 20. The embodiment of the hard disk fixing device 30 corresponds to Embodiment 1. For ease of reading, this embodiment of the hard disk fixing device 30 will not repeat the details of the aforementioned Embodiment 1, but it should be clear that the hard disk fixing device 30 in this embodiment corresponds to all the contents of the aforementioned Embodiment 1.

[0078] The hard drive assembly provided in this application, through the design of a universal bracket 1 and a detachable adapter 2, can flexibly adapt to hard drive modules of different lengths, significantly improving hardware versatility and deployment flexibility. Manufacturers only need to produce one type of bracket 1 and a small number of adapters 2 to meet various hard drive installation needs, effectively reducing the types of components and lowering overall costs. The bracket 1 can be permanently fixed inside the motherboard 80 or chassis; when replacing a hard drive, there is no need to disassemble the bracket 1, only the corresponding adapter 2 needs to be installed or removed according to the hard drive size. All connections are achieved through a flexible snap-fit ​​structure, supporting tool-free operation; installation and removal can be completed by manual pressing, making operation simple and quick.

[0079] In some embodiments, the hard disk assembly further includes: a first thermal pad 40, a second thermal pad 50, and a heat sink 60, for dissipating heat for the first module 10 or the second module 20; the first thermal pad 40 and the second thermal pad 50 are bonded to the surface of the first module 10 or the second module 20, and the heat sink 60 is snapped into the bracket 1; wherein, the length of the first thermal pad 40 is adapted to the length of the second module 20, the total length of the first thermal pad 40 and the second thermal pad 50 is adapted to the length of the first module 10, and the length of the heat sink 60 is adapted to the length of the bracket 1.

[0080] The first thermal pad 40 and the second thermal pad 50 can both be made of flexible materials with high thermal conductivity (such as thermally conductive silicone pads, graphene thermal pads, etc.), and can be directly adhered to the surface of the first module 10 or the second module 20 for heat conduction. The heat sink 60 can be made of a metal material with good thermal conductivity and heat dissipation properties (such as aluminum or copper). It can be fixedly connected to the bracket 1 through a snap-fit ​​structure (such as clips, elastic arms, etc.), covering the first module 10 or the second module 20, without the need for additional screws, making installation simple.

[0081] The length of the first thermal pad 40 matches that of the second module 20, ensuring complete coverage of its main heat-generating area. The total length of the first thermal pad 40 and the second thermal pad 50 matches that of the first module 10. When the long first module 10 is installed, the two thermal pads can be spliced ​​together or arranged continuously along their length to cover the entire heat-generating area. The length of the heat sink 60 matches that of the bracket 1, ensuring that the heat sink 60 can completely cover and press against the hard drive regardless of the type of hard drive installed, achieving efficient heat conduction.

[0082] When installing the first module 10, if Figure 8 As shown, a first thermal pad 40 and a second thermal pad 50 must be used simultaneously. The total length of the two thermal pads matches that of the first module 10, and thermal pads can be adhered to both the top and bottom surfaces of the first module 10. The first module 10 is connected to the base plate 103 of the bracket 1 via the thermal pads, and is in close contact with the heat sink 60 above via the thermal pads. Heat is conducted to the heat sink 60 via the thermal pads and dissipated quickly.

[0083] When installing the second module 20, if Figure 9 As shown, only the first thermal pad 40 is needed. The length of the first thermal pad 40 matches that of the second module 20. Similarly, thermal pads can be glued to the top and bottom surfaces of the second module 20 to connect it to the bracket 1 and to contact the heat sink 60 above, efficiently transferring heat to the heat sink 60.

[0084] By combining a universal heatsink 60 and two optional thermal pads, unified thermal management of hard drives of different lengths is achieved. This eliminates the need to design dedicated heatsinks for different drive sizes, greatly simplifying component selection and reducing production and maintenance costs. Maintenance personnel only need to decide whether to use the second thermal pad 50 based on the type of hard drive installed, making the operation simple, flexible, and efficient. The combination of the thermal pads and the heatsink 60 effectively reduces the hard drive's operating temperature, preventing overheating and performance throttling.
