Description

Technical Field

[0001] This application relates to the field of data storage device securing technology, and in particular to a hard disk securing device and chassis. Background Technology

[0002] As the primary storage hardware in a computer, the hard drive is typically mounted on a hard drive bracket. To mitigate the interference and installation difficulties caused by manufacturing and assembly tolerances, a gap is provided between the hard drive connector and the backplane module connector of the chassis to absorb the accumulated tolerances during hard drive assembly within the bracket. However, if these accumulated tolerances become excessive, this gap can often lead to poor signal transmission between the hard drive connector and the backplane module connector. Summary of the Invention

[0003] In view of this, it is necessary to provide a hard drive mounting device and chassis that can improve the problem of poor signal transmission between the hard drive connector and the backplane module connector.

[0004] In a first aspect, embodiments of this application provide a hard disk mounting device, including a sliding bracket, a hard disk bracket, and an elastic member. The sliding bracket is used to fix the hard disk body and is slidably disposed on the hard disk bracket along a first direction for inserting a connector of the hard disk body into a connector of a backplane module along the first direction. The elastic member is disposed between the sliding bracket and the hard disk bracket, and the elastic member has an elastic force that drives the sliding bracket to move along the first direction.

[0005] In the above embodiments, the sliding bracket is used to fix the hard drive body. The sliding bracket drives the connector of the hard drive body to slide along the first direction on the hard drive bracket and is used to connect to the connector of the backplane module, so that the hard drive body has room to move, thereby improving the problem of hard drive body interference and inconvenience in installation caused by tolerances accumulated in manufacturing and assembly. The first direction refers to the direction in which the connection port of the hard drive body faces the backplane module and docks with the backplane module. The elastic element is disposed between the sliding bracket and the hard drive fixing device, and the elastic element can drive the sliding bracket to slide along the first direction, so that when the hard drive fixing device is docked with the backplane module, the hard drive body installed on the hard drive fixing device always has a clamping force pressing against the backplane module. The sliding bracket, which is slidably disposed on the hard drive bracket, can absorb accumulated tolerances, and the elastic element can press the hard drive body against the backplane module to eliminate the influence of the gap between the hard drive body and the backplane module on the connection between the hard drive body and the backplane module, thereby improving the problem of poor signal transmission between the hard drive fixing device and the backplane module.

[0006] In at least one embodiment, the hard disk fixing device further includes a baffle plate and a positioning post. The baffle plate is fixed to the inner wall of the hard disk bracket and has a through hole. The positioning post is fixed to the side wall of the sliding bracket and passes through the through hole. The elastic element is sleeved on the outer peripheral surface of the positioning post. One end of the elastic element is pressed against the side wall of the sliding bracket, and the other end of the elastic element is pressed against the baffle plate.

[0007] In the above embodiment, one end of the elastic element is pressed against the side wall of the sliding bracket, and the other end of the elastic element is pressed against the abutment plate. The abutment plate is fixed to the inner wall of the hard drive bracket, so that the elastic element has an independent mounting base. The abutment plate has a through hole through which a positioning post disposed on the side wall of the sliding bracket passes, and the elastic element is sleeved on the outer peripheral surface of the positioning post, so that the positioning post can constrain the position of the elastic element and improve the problem of positional instability of the elastic element during deformation.

[0008] In at least one embodiment, the hard disk mounting device further includes a limiting member connected to one of the hard disk bracket or the sliding bracket, the limiting member being used to stop the other of the sliding bracket or the hard disk bracket to limit the sliding range of the sliding bracket along the first direction.

[0009] In the above embodiments, during the sliding of the sliding bracket along the first direction on the hard drive bracket, the sliding bracket cannot be allowed to slide on the hard drive bracket indefinitely to prevent the sliding bracket from causing the hard drive body to detach from the hard drive bracket. When the sliding bracket slides beyond the range limited by the limiting member, the limiting member stops the sliding bracket from sliding along the first direction, thereby improving the problem of the sliding bracket causing the hard drive body to detach from the hard drive bracket and improving the installation convenience of the hard drive body.

[0010] In at least one embodiment, the limiting member is a limiting post, and the side wall of the sliding bracket is provided with a limiting opening. The limiting post passes through the limiting opening to be fixed to the inner wall of the hard disk bracket. The length direction of the limiting opening is along the first direction, and the length of the limiting opening is greater than the diameter of the limiting post, so that the sliding bracket can slide relative to the hard disk bracket along the first direction.

[0011] In the above embodiment, the limiting post is fixed to the inner wall of the hard drive bracket, and the limiting post passes through the limiting opening on the side wall of the sliding bracket. Since the length direction of the limiting opening is along the first direction, and the length of the limiting opening is greater than the diameter of the limiting post, the two ends of the limiting opening in the length direction are the movement range of the limiting post, thereby limiting the sliding range of the sliding bracket. The fixing method between the limiting post and the hard drive bracket is simple, and the processing method of the limiting opening is also simple. Through the cooperation of the limiting post and the limiting opening, the limiting function can be achieved while reducing processing costs and improving the space utilization of the hard drive fixing device.

[0012] In at least one embodiment, the hard drive mounting device further includes a heat sink fixed to the inner wall of the hard drive bracket, the heat sink being used to contact the hard drive body to absorb heat from the hard drive body.

[0013] In the above embodiment, the heat sink is fixed to the inner wall of the hard drive bracket and located on the side of the hard drive body. During the operation of the hard drive body and the accumulation of heat, the heat sink can absorb the heat of the hard drive body, thereby improving the problem of performance degradation or storage structure damage caused by heat accumulation and improving the service life of the hard drive body.

[0014] Secondly, embodiments of this application provide a chassis for fixing the backplane module and the hard drive body. The chassis includes a casing, a hard drive mounting bracket, and a plurality of the aforementioned hard drive fixing devices. The hard drive mounting bracket is fixed inside the casing, the backplane module is disposed on the side of the hard drive mounting bracket, the hard drive fixing devices are installed on the hard drive mounting bracket, and the connector of the hard drive body is plugged into the connector of the backplane module.

[0015] In the above embodiments, both the backplane module and the hard drive mounting bracket are fixed inside the chassis, thereby protecting the backplane module and the hard drive mounting bracket through the chassis. The backplane module is located on the side of the hard drive mounting bracket, and multiple hard drive mounting devices are installed on the hard drive mounting bracket to facilitate the docking of multiple hard drive mounting devices with the backplane module.

[0016] In at least one embodiment, the inner surface of the hard drive mounting bracket is provided with a plurality of partitions, the plurality of partitions being evenly spaced along a second direction for mounting the hard drive mounting device between two adjacent partitions, the second direction being perpendicular to the first direction.

[0017] In the above embodiments, multiple partitions are evenly arranged on the inner surface of the hard drive mounting bracket along the second direction, thereby facilitating the installation of hard drive mounting devices between adjacent partitions. The second direction refers to the direction along the length of the backplate module. The multiple partitions are evenly arranged along the second direction so that multiple hard drive mounting devices can be installed side by side on the hard drive mounting bracket along the second direction, thereby improving the installation stability of the hard drive mounting devices.

[0018] In at least one embodiment, at least three separators are provided, each separator including a first straight plate, a second straight plate and a third straight plate, the first straight plate and the third straight plate being parallel, the two ends of the second straight plate being connected to the first straight plate and the third straight plate respectively, the angle between the second straight plate and the first straight plate being an obtuse angle, and the angle between the second straight plate and the third straight plate being an obtuse angle.

[0019] Three adjacent separators form a group of separators, in which:

[0020] Along the second direction, the separator located at one end is the first unit;

[0021] Along the second direction, the middle separator is the second unit;

[0022] Along the second direction, the separator located at the other end is a third unit;

[0023] The third straight plate of the first unit and the first straight plate of the second unit are used to clamp the first hard disk fixing device in the second direction; the third straight plate of the second unit and the first straight plate of the third unit are used to clamp the second hard disk fixing device in the second direction.

[0024] In the above embodiments, among the multiple separators, three adjacent separators can form a separator group, so that the setting method of each separator is the same. All separators can be processed using the same method, thereby improving the processing efficiency of the separators and reducing processing costs. The third straight plate of the first unit is used to limit one side of a hard drive mounting device, and the first straight plate of the second unit is used to limit the other side of the hard drive mounting device; the third straight plate of the second unit is used to limit one side of another hard drive mounting device, and the first straight plate of the third unit is used to limit the other side of the hard drive mounting device. A separator group can accommodate two hard drive mounting devices, and the first and third straight plates of the second unit both limit the two hard drive mounting devices. Simultaneously, since the first and third straight plates are parallel and separated, the third straight plates of the first and second units can enlarge the opening for the hard drive mounting device to enter the separator group, thus facilitating the insertion of the hard drive mounting device into the hard drive mounting bracket.

[0025] In at least one embodiment, the inner surface of the hard drive bracket is provided with a plurality of locking slots, and the hard drive fixing device further includes a locking component, which is disposed at the end of the hard drive bracket away from the plug-in member;

[0026] The locking assembly includes a mounting block and a locking block. The mounting block is fixed to the hard drive bracket, and the locking block is hinged to the mounting block about a hinge axis. The locking block includes a locking handle and a hard drive hook. The locking block is configured to rotate the locking handle about the hinge axis to drive the hard drive hook into or out of the locking slot.

[0027] In the above embodiment, the mounting block is fixed to the side of the hard disk bracket. After the hard disk fixing device is pushed into the hard disk fixing frame, by rotating the locking handle, since the hard disk hook is set on the side away from the locking handle of the hinge axis, when the locking block is parallel to the mounting block, the hard disk hook is located in the locking groove, so that the side wall of the locking groove stops the hard disk hook, thereby restricting the position of the hard disk fixing device and improving the installation convenience of the hard disk fixing device.

[0028] In at least one embodiment, the locking assembly further includes a locking button disposed on the side of the mounting block away from the hinge axis, the locking button being hinged to the mounting block; the locking block further includes a locking boss disposed on the side of the locking handle away from the hard disk hook; when the hard disk hook enters the locking slot, the locking button stops the locking boss near the side of the mounting block.

[0029] In the above embodiment, since one end of the locking block is hinged to the mounting block, when the locking block is parallel to the mounting block, the locking button approaches the side stop locking boss of the mounting block, thereby locking the locking block, so that the side wall of the locking groove stops the hard disk hook and restricts the position of the hard disk fixing device.

[0044] Unless otherwise explicitly specified and limited, the terms “installation,” “connection,” “fixation,” etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium.

[0045] Those skilled in the art will understand the specific meaning of the above terms in this application according to the specific circumstances. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0046] Embodiments of this application provide a hard drive mounting device, including a sliding bracket, a hard drive bracket, and an elastic member. The sliding bracket is used to fix the hard drive body and is slidably disposed on the hard drive bracket along a first direction for inserting the connector of the hard drive body into the connector of a backplane module along the first direction. The elastic member is disposed between the sliding bracket and the hard drive bracket and has an elastic force that drives the sliding bracket to move along the first direction.

[0047] In the above embodiments, the sliding bracket is used to fix the hard drive body. The sliding bracket drives the connector of the hard drive body to slide along the first direction on the hard drive bracket and is used to connect to the connector of the backplane module, so that the hard drive body has room to move, thereby improving the problem of hard drive body interference and inconvenience in installation caused by tolerances accumulated in manufacturing and assembly. The first direction refers to the direction in which the connection port of the hard drive body faces the backplane module and docks with the backplane module. The elastic element is disposed between the sliding bracket and the hard drive fixing device, and the elastic element can drive the sliding bracket to slide along the first direction, so that when the hard drive fixing device is docked with the backplane module, the hard drive body installed on the hard drive fixing device always has a clamping force pressing against the backplane module. The sliding bracket, which is slidably disposed on the hard drive bracket, can absorb accumulated tolerances, and the elastic element can press the hard drive body against the backplane module to eliminate the influence of the gap between the hard drive body and the backplane module on the connection between the hard drive body and the backplane module, thereby improving the problem of poor signal transmission between the hard drive fixing device and the backplane module.

[0048] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0049] Please see Figure 1 Some embodiments of this application provide a chassis 100, including a housing 10, a backplane module 20, a hard drive mounting bracket 30, and a plurality of hard drive mounting devices 40. The housing 10 includes a bottom shell 12 and a top cover 11, with a fixing cavity 13 formed between the bottom shell 12 and the top cover 11. The backplane module 20 and the hard drive mounting bracket 30 are both fixed within the fixing cavity 13 of the housing 10, thereby protecting the backplane module 20 and the hard drive mounting bracket 30 through the housing 10. The hard drive mounting bracket 30 is located at one end of the fixing cavity 13, facilitating the installation of the hard drive mounting devices 40 onto the hard drive mounting bracket 30.

[0050] The backplane module 20 is located on the side of the hard disk mounting bracket 30. Multiple hard disk mounting devices 40 are mounted on the hard disk mounting bracket 30 along a first direction X. The hard disk mounting devices 40 are used to mount the hard disk body 41. The hard disk body 41 includes a connector 411 and a storage medium 412 electrically connected to the connector 411. The connector 411 is used to electrically connect to the backplane module 20. The first direction X refers to the direction in which the hard disk mounting bracket 30 faces the backplane module 20, allowing the hard disk mounting devices 40 to directly interface with the backplane module 20.

[0051] In some embodiments, the backplane module 20 includes a mounting backplane 21 and a plurality of connectors 22. The plurality of connectors 22 are evenly arranged along a second direction Y and fixed to the side of the mounting backplane 21 to facilitate mating with the connectors 411 of the hard disk body 41 in the hard disk mounting device 40. The second direction Y is perpendicular to the first direction X.

[0052] Please see Figure 2 In some embodiments, the hard disk mounting bracket 30 includes a fixed base plate 31 and a fixed top plate 32, which together form a mounting cavity 33 with openings at both ends along a first direction X. The hard disk mounting device 40 is mounted in the hard disk mounting bracket 30 along the first direction X. The sides of the hard disk mounting device 40 in the width direction are respectively attached to the fixed base plate 31 and the fixed top plate 32, thereby facilitating the sliding mounting of the hard disk mounting device 40 to the hard disk mounting bracket 30 along the first direction X.

[0053] In some embodiments, the hard disk mounting bracket 30 is provided with multiple partition plates 34, which are detachably fixed between the top mounting plate 32 and the bottom mounting plate 31, thereby dividing the mounting cavity 33 into multiple areas. On the one hand, each area is heat-insulated to improve the problem of heat accumulation. On the other hand, by partitioning the mounting cavity 33, the hard disk mounting devices 40 inserted into the corresponding areas can be classified and managed, improving the ease of identification of the hard disk mounting devices 40.

[0054] In some embodiments, the hard disk mounting bracket 30 is provided with two partition boards 34, thereby dividing the mounting cavity 33 into three areas.

[0055] Please see Figure 2 In some embodiments, the inner bottom surface of the fixed base plate 31 is provided with a plurality of partitions 311 for mounting hard disk mounting devices 40 between adjacent partitions 311. The plurality of partitions 311 are evenly spaced along the second direction Y so that the plurality of hard disk mounting devices 40 can be mounted side by side on the hard disk mounting frame 30 along the second direction Y, thereby improving the installation stability of the hard disk mounting devices 40.

[0056] In some embodiments, a retaining boss 312 is provided on the base plate 31 at a position corresponding to each partition 311 along the first direction X. The corresponding position means that when the partition 311 acts on the hard disk mounting device 40 to limit the position of the hard disk mounting device 40 on the base plate 31, the retaining boss 312 corresponding to the partition 311 stops the side of the hard disk mounting device 40, thereby further improving the installation stability of the hard disk mounting device 40.

[0057] In some embodiments, both the partition 311 and the edge boss 312 are formed by sheet metal stamping to improve the processing convenience of the partition 311 and the edge boss 312. Specifically, a fixed base plate 31 is formed by sheet metal stamping, and the partition 311 and the edge boss 312 are formed on the fixed base plate 31. Forming holes are formed on the fixed base plate 31 at positions corresponding to the partition 311 and the edge boss 312. The shape of these forming holes is similar to that of the partition 311 or the edge boss 312, and the forming holes connect to the outside of the mounting cavity 33, improving the heat dissipation effect of the mounting cavity 33. This form of forming the partition 311 and the edge boss 312 by sheet metal stamping, on the one hand, facilitates the processing of the partition 311 and the edge boss 312 and reduces processing costs; on the other hand, the forming holes generated when forming the partition 311 and the edge boss 312 can also improve the heat dissipation performance of the mounting cavity 33 formed by the hard disk mounting bracket 30.

[0058] In some embodiments, each partition 311 and each edge protrusion 312 is provided with an edge strip 313 along the third direction Z, which is perpendicular to the first direction X and the second direction Y, and extends from the fixed base plate 31 to the fixed top plate 32. The edge strip 313 is disposed on the bottom surface of the fixed top plate 32 and is used to cooperate with the corresponding partition 311 to stop the other side of the hard disk mounting device 40 in the third direction Z, thereby further improving the installation stability of the hard disk mounting device 40.

[0059] In some embodiments, the edge strip 313 is formed by sheet metal stamping to improve the processing convenience of the edge strip 313.

[0060] Please see Figure 2 and Figure 3 In some embodiments, at least three separators 311 are provided. The separator 311 includes a first straight plate 3111, a second straight plate 3112, and a third straight plate 3113. The first straight plate 3111 and the third straight plate 3113 are parallel and separated by a distance. The two ends of the second straight plate 3112 are connected to the first straight plate 3111 and the third straight plate 3113, respectively. The angle between the second straight plate 3112 and the first straight plate 3111 is an obtuse angle, and the angle between the second straight plate 3112 and the third straight plate 3113 is an obtuse angle.

[0061] Three adjacent separators 311 form a separator group 310, ensuring that each separator 311 is configured in the same way. All separators 311 can be processed using the same method, thereby improving processing efficiency and reducing processing costs. Within a separator group 310, along the second direction Y, the separator 311 located at one end is the first unit 3101, the separator 311 located in the middle is the second unit 3102, and the separator 311 located at the other end is the third unit 3103.

[0062] The third straight plate 3113 of the first unit 3101 is used to limit one side of the first hard disk mounting device 40, and the first straight plate 3111 of the second unit 3102 is used to limit the other side of the first hard disk mounting device 40; the third straight plate 3113 of the second unit 3102 is used to limit one side of the second hard disk mounting device 40, and the first straight plate 3111 of the third unit 3103 is used to limit the other side of the second hard disk mounting device 40. A set of partitions 310 can accommodate two hard disk mounting devices 40, and the first straight plate 3111 and the third straight plate 3113 of the second unit 3102 both limit the hard disk mounting devices 40 on both sides. Meanwhile, the first straight plate 3111 and the third straight plate 3113 are parallel and separated. Therefore, the third straight plate 3113 of the first unit 3101 and the third straight plate 3113 of the second unit 3102 can increase the opening for the hard disk mounting device 40 to enter the partition group 310. The second straight plate 3112 of the second unit 3102 can guide the hard disk mounting device 40 into the partition group 310, thereby facilitating the insertion of the hard disk mounting device 40 into the hard disk mounting bracket 30.

[0063] On the one hand, since each partition 311 has the same shape, when the fixed base plate 31 is formed by sheet metal stamping, the fixed base plate 31 is subjected to more uniform force along the second direction Y, with fewer areas of stress concentration, thus improving the yield of the fixed base plate 31. On the other hand, this fixed base plate 31 does not need to be formed by sheet metal stamping separately. Since each partition 311 has the same shape, and a hard drive mounting device 40 can be installed between every two adjacent partitions 311, compared to setting spaced clamping components on the fixed base plate 31, by clamping one hard drive mounting device 40 with each clamping component, the gap between the clamping components can be eliminated, improving the space utilization of the fixed base plate 31.

[0064] In some embodiments, the bottom surface of the fixed base plate 31 is also provided with a plurality of locking slots 314, which are directly opposite the opening of the partition group 310, so that after the hard disk mounting device 40 is installed on the hard disk mounting bracket 30, the position can be locked by the locking slots 314.

[0065] Please see Figure 4 and Figure 5 Some embodiments of this application also provide a hard disk mounting device 40 for mounting the hard disk body 41. Due to accumulated tolerances during the manufacturing and assembly process of the hard disk mounting device 40, directly connecting the hard disk mounting device 40 to the backplane module 20 may result in insufficient mounting space, preventing installation. If the mounting space for the hard disk mounting device 40 is arbitrarily increased, vibrations during transportation may cause gaps between the hard disk body 41 on the hard disk mounting device 40 and the backplane module 20, leading to unstable signal transmission.

[0066] In some embodiments, the hard disk mounting device 40 includes a sliding bracket 42, a hard disk bracket 43, and an elastic member 44. The sliding bracket 42 is used to fix the hard disk body 41. The hard disk body 41 includes a connector 411 and a storage medium 412 electrically connected to the connector 411, the connector 411 being used to electrically connect to the connector 22. The hard disk body 41 is fixed to the sliding bracket 42, the sliding bracket 42 being slidably disposed on the hard disk bracket 43 along a first direction X, driving the hard disk body 41 to slide along the first direction X, so that the hard disk body 41 has room for movement, thereby improving the problem of interference and inconvenience in installation caused by tolerances accumulated in manufacturing and assembly. The elastic member 44 is disposed between the sliding bracket 42 and the hard disk mounting device 40, and the elastic member 44 has a clamping force to drive the sliding bracket 42 to slide along the first direction X. The hard disk body 41, which is slidably mounted on the hard disk bracket 43, can absorb accumulated tolerances, and the elastic member 44 can press the hard disk body 41 tightly against the backplane module 20 to eliminate the impact of the gap between the hard disk body 41 and the backplane module 20 on the connection between the hard disk mounting device 40 and the backplane module 20, thereby improving the problem of poor signal transmission between the hard disk mounting device 40 and the backplane module 20.

[0067] Please see Figure 5 and Figure 6 In some embodiments, the hard disk mounting device 40 further includes a baffle plate 45 and a positioning post 46. The positioning post 46 is fixed to the side wall of the sliding bracket 42 facing the baffle plate 45, and the baffle plate 45 is fixed to the inner wall of the hard disk bracket 43. The baffle plate 45 is provided with a through hole 451 through which the positioning post 46 passes. One end of the elastic member 44 is pressed against the side wall of the sliding bracket 42, and the other end of the elastic member 44 is pressed against the baffle plate 45. The elastic member 44 is sleeved on the outer peripheral surface of the positioning post 46, so that the positioning post 46 can constrain the position of the elastic member 44 and improve the problem of unstable position of the elastic member 44 during deformation.

[0068] In some embodiments, the baffle 45 is integrally formed onto the hard drive bracket 43 by sheet metal bending, thereby facilitating the forming of the baffle 45. In other embodiments, the baffle 45 can also be fixed to the hard drive bracket 43 by welding, bolting, or other methods.

[0069] In some embodiments, the positioning post 46 is fixed to the side wall of the sliding bracket 42 by riveting to improve the ease of installation of the positioning post 46.

[0070] In some embodiments, the elastic element 44 is configured as a compression spring, with one end pressing against the side wall of the sliding bracket 42 and the other end pressing against the abutment plate 45, thereby improving installation convenience. In other embodiments, the elastic element 44 can also be configured in other forms; for example, the elastic element 44 can also be configured as a pair of mutually repelling magnetic elements.

[0071] Please see Figure 5 and Figure 6 In some embodiments, the hard disk fixing device 40 further includes a limiting member 47, which is disposed between the hard disk bracket 43 and the sliding bracket 42. The limiting member 47 is used to stop the sliding bracket 42 from sliding along the first direction X of the hard disk bracket 43, thereby limiting the sliding range of the sliding bracket 42 along the first direction X, thereby improving the problem of the sliding bracket 42 causing the hard disk body 41 to detach from the hard disk bracket 43 and improving the installation convenience of the hard disk body 41.

[0072] In some embodiments, the limiting member 47 is a limiting post 471, which is fixed to the inner wall of the hard disk bracket 43 and protrudes toward the sliding bracket 42. A limiting opening 421 is provided on the side wall of the sliding bracket 42, the length of which is along the first direction X, and the length of the limiting opening 421 is greater than the diameter of the limiting post 471. The limiting post 471 passes through the limiting opening 421 to limit the sliding range of the sliding bracket 42 along the first direction X.

[0073] In some embodiments, the limiting post 471 is fixedly connected to the side wall of the hard disk bracket 43 by riveting, and the limiting opening 421 is formed into a rectangular cut by punching. The limiting post 471 is fixed to the side wall of the hard disk bracket 43 and partially located within the limiting opening 421. The fixing method between the limiting post 471 and the hard disk bracket 43 is simple, and the processing method of the limiting opening 421 is also simple. Through the cooperation of the limiting post 471 and the limiting opening 421, the limiting function can be achieved while reducing processing costs and improving the space utilization of the hard disk fixing device 40.

[0074] In some embodiments, the limiting member 47 is a pair of limiting nuts, which are threaded onto the outer peripheral surface of the positioning post 46, with one limiting nut located on one side of the abutment plate 45 and the other limiting nut located on the other side of the abutment plate 45. The maximum outer diameter of the limiting nut is larger than the diameter of the through hole 451, so that the abutment plate 45 can stop the positioning post 46 on which the limiting nut is installed, thereby limiting the sliding range of the sliding bracket 42 along the first direction X.

[0075] In some embodiments, by determining the distance between the two limiting nuts and the abutment plate 45, and locking the limiting nuts in position using semi-permanent threadlocking adhesive, the positional stability of the limiting nuts is improved, thereby improving the positional stability of the sliding bracket 42. Semi-permanent threadlocking adhesive refers to a type of threadlocking adhesive that can fill the gaps between threads to prevent bolt loosening, help the bolt resist vibration and impact, and whose adhesive properties can be broken off with tools when disassembly is required.

[0076] Please see Figure 4 and Figure 5 and combined Figure 1 In some embodiments, the hard disk mounting device 40 further includes a heat sink 48, which is fixed to the inner wall of the hard disk bracket 43 and contacts the side of the hard disk body 41. A heat-conducting column 481 is integrally provided on the side of the heat sink 48, which can press against the fixed top plate 32. Therefore, during the operation of the hard disk body 41 and the accumulation of heat, the heat sink 48 can absorb the heat from the hard disk body 41, improving the performance degradation or storage structure damage caused by heat accumulation and extending the service life of the hard disk body 41.

[0077] In some embodiments, two heat dissipation bars 48 are provided, which are arranged side by side on the side of the hard drive bracket 43 to improve the heat dissipation performance of the hard drive mounting device 40.

[0078] Please see Figure 7 and Figure 8 In some embodiments, the hard disk mounting device 40 further includes a locking component 49 disposed on the side of the hard disk bracket 43 facing the opposite direction to the first direction X. The locking component 49 includes a mounting block 491 and a locking block 492. The mounting block 491 is bolted to the side of the hard disk bracket 43, and the locking block 492 is hinged to the mounting block 491, with a hinge axis at the hinge point. The locking block 492 includes a locking handle 4921 and a hard disk hook 4922, located on the side of the hinge axis away from the locking handle 4921, such that the locking handle 4921 and the hard disk hook 4922 have opposite rotational directions. When the locking block 492 is parallel to the mounting block 491, the hard disk hook 4922 is located within a locking groove 314, such that the sidewall of the locking groove 314 stops the hard disk hook 4922, thereby restricting the position of the hard disk mounting device 40 and improving the ease of installation of the hard disk mounting device 40.

[0079] Please see Figure 7 and Figure 8 and combined Figure 1In some embodiments, the locking assembly 49 further includes a locking button 493, which is located on the side of the mounting block 491 away from the hinge axis. The locking button 493 is hinged to the mounting block 491, and the hinge axis between the locking button 493 and the mounting block 491 is located near the center of the mounting block 491. The locking block 492 also includes a locking boss 4923, which is located on the side of the locking handle 4921 away from the hard disk hook 4922. When the locking block 492 is parallel to the mounting block 491, the locking button 493 stops the locking boss 4923 near the side of the mounting block 491. The locking boss 4923 is located diagonally above the hinge axis between the locking button 493 and the mounting block 491, so that the locking boss 4923 cannot drive the locking button 493 to rotate, thereby locking the locking block 492. This causes the side wall of the locking groove 314 to stop the hard disk hook 4922, restricting the position of the hard disk fixing device 40.

[0080] In some embodiments, a torsion spring 494 is provided at the hinge between the locking block 492 and the mounting block 491 to drive the locking block 492 to rotate, so that the locking boss 4923 has a driving force away from the locking button 493. By pressing the locking button 493, the torsion spring 494 drives the locking boss 4923 to separate from the locking button 493, thereby improving the ease of disassembly and assembly of the hard disk mounting device 40.

[0081] In addition, those skilled in the art may make other changes within the spirit of this application. Of course, all such changes made in accordance with the spirit of this application should be included within the scope disclosed in this application.
