Description

Technical Field

[0001] The present application relates to the technical field of data storage device locking, and in particular to a hard disk fixing device and a chassis. Background Art

[0002] As the most important storage hardware of the computer, the hard disk is usually fixed on the hard disk bracket. In order to improve the problem of hard disk interference and inconvenience in installation caused by the accumulated tolerances in manufacturing and assembly, a gap is reserved between the connector of the hard disk and the connector of the backplane module of the chassis to absorb the accumulated tolerances of the hard disk when assembled in the hard disk bracket. Once the accumulated tolerance is too large, this gap often causes poor signal transmission between the connector of the hard disk and the connector of the backplane module. Summary of the invention

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

[0004] In a first aspect, an embodiment of the present application provides a hard disk fixing device, comprising a sliding bracket, a hard disk bracket and an elastic member. The sliding bracket is used to fix the hard disk body, and the sliding bracket is slidably arranged on the hard disk bracket along a first direction, so as to plug the plug-in of the hard disk body into the connector of the backplane module along the first direction. The elastic member is arranged 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 embodiment, the sliding bracket is used to fix the hard disk body, and the sliding bracket drives the plug-in of the hard disk body to slide on the hard disk bracket along the first direction and is used to plug the connector of the backplane module, so that the hard disk body has a movable space, thereby improving the problem that the hard disk body interferes with and is inconvenient to install due to the tolerance accumulated in manufacturing and assembly. The first direction refers to the direction in which the connection port of the hard disk body faces the backplane module and docks with the backplane module. The elastic member is arranged between the sliding bracket and the hard disk fixing device, and the elastic member can drive the sliding bracket to slide along the first direction, so that when the hard disk fixing device is docked with the backplane module, the hard disk body installed on the hard disk fixing device always has a pressing force pressed against the backplane module. The sliding bracket slidingly arranged on the hard disk bracket can absorb the accumulated tolerance, and the elastic member can press the hard disk body against the backplane module to eliminate the influence of the gap between the hard disk body and the backplane module on the connection between the hard disk body and the backplane module, thereby improving the problem of poor signal transmission between the hard disk fixing device and the backplane module.

[0006] In at least one embodiment, the hard disk fixing device also includes a stop plate and a positioning column, wherein the stop plate is fixed to the inner wall of the hard disk bracket, the stop plate is provided with a through hole, the positioning column is fixed to the side wall of the sliding bracket and passes through the through hole, the elastic member is sleeved on the outer peripheral surface of the positioning column, one end of the elastic member is pressed against the side wall of the sliding bracket, and the other end of the elastic member is pressed against the stop plate.

[0007] In the above embodiment, one end of the elastic member is pressed against the side wall of the sliding bracket, and the other end of the elastic member is pressed against the retaining plate, which is fixed to the inner wall of the hard disk bracket, so that the elastic member has an independent installation base. The retaining plate has a through hole, and the positioning column arranged on the side wall of the sliding bracket passes through the through hole, and the elastic member is sleeved on the outer peripheral surface of the positioning column, so that the positioning column can constrain the position of the elastic member, thereby improving the problem of unstable position of the elastic member during deformation.

[0008] In at least one embodiment, the hard disk fixing device also includes a limit member, which is connected to one of the hard disk bracket or the sliding bracket, and the limit member is 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 embodiment, when the sliding bracket slides on the hard disk bracket along the first direction, the sliding bracket cannot slide on the hard disk bracket without restriction, so as to prevent the sliding bracket from driving the hard disk body to separate from the hard disk bracket. When the sliding bracket slides beyond the range limited by the limiter, the limiter stops the sliding bracket from sliding along the first direction of the hard disk bracket, thereby improving the problem of the sliding bracket driving the hard disk body to separate from the hard disk bracket and improving the installation convenience of the hard disk body.

[0010] In at least one embodiment, the limiting member is a limiting column, and the side wall of the sliding bracket is provided with a limiting opening, the limiting column 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 column, so that the sliding bracket can slide along the first direction relative to the hard disk bracket.

[0011] In the above embodiment, the limiting post is fixed to the inner wall of the hard disk bracket, and the limiting post passes through the limiting opening of 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 moving range of the limiting post, thereby limiting the sliding range of the sliding bracket. The fixing method of the limiting post and the hard disk bracket is simple, and the processing method of the limiting opening is simple. Through the cooperation of the limiting post and the limiting opening, the processing cost can be reduced while realizing the limiting function, and the space utilization rate of the hard disk fixing device can be improved.

[0012] In at least one embodiment, the hard disk fixing device further includes a heat dissipation bar, which is fixed to the inner wall of the hard disk bracket, and the heat dissipation bar is used to contact the hard disk body to absorb the heat of the hard disk body.

[0013] In the above embodiment, the heat dissipation strip is fixed to the inner wall of the hard disk bracket and is located on the side of the hard disk body. When the hard disk body is working and generates heat accumulation, the heat dissipation strip can absorb the heat of the hard disk body, thereby improving the problem of performance degradation or storage structure damage of the hard disk body due to heat accumulation, thereby increasing the service life of the hard disk body.

[0014] In a second aspect, an embodiment of the present application provides a chassis for fixing the backplane module and the hard disk body, the chassis comprising a casing, a hard disk fixing frame and a plurality of the above-mentioned hard disk fixing devices; the hard disk fixing frame is fixed in the casing, the backplane module is arranged on the side of the hard disk fixing frame, the hard disk fixing device is installed on the hard disk fixing frame, and the connector of the hard disk body is plugged into the connector of the backplane module.

[0015] In the above embodiment, the backplane module and the hard disk fixing frame are both fixed in the housing, so that the backplane module and the hard disk fixing frame are protected by the housing. The backplane module is arranged on the side of the hard disk fixing frame, and a plurality of hard disk fixing devices are installed on the hard disk fixing frame to facilitate the docking of the plurality of hard disk fixing devices with the backplane module.

[0016] In at least one embodiment, a plurality of partitions are disposed on the inner surface of the hard disk fixing frame, and the plurality of partitions are evenly spaced along a second direction for installing the hard disk fixing device between two adjacent partitions, and the second direction is perpendicular to the first direction.

[0017] In the above embodiment, the inner surface of the hard disk fixing frame is evenly provided with a plurality of partitions along the second direction, so that the hard disk fixing device can be easily installed between two adjacent partitions. The second direction refers to the direction along the length of the backplane module, and the plurality of partitions are evenly provided along the second direction, so that the plurality of hard disk fixing devices can be installed side by side on the hard disk fixing frame along the second direction, thereby improving the installation stability of the hard disk fixing device.

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

[0019] Three adjacent partitions form a partition group, in which:

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

[0021] Along the second direction, the partition located in the middle is the second unit;

[0022] Along the second direction, the partition located at the other end thereof 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 embodiment, among the multiple partitions, three adjacent partitions can form a partition group, so that the setting method of each partition is the same, and all the partitions can be processed by the same processing method, thereby improving the processing efficiency of the partitions and reducing the processing cost. The third straight plate of the first unit is used to limit one side of a hard disk fixing device, and the first straight plate of the second unit is used to limit the other side of the hard disk fixing device; the third straight plate of the second unit is used to limit one side of another hard disk fixing device, and the first straight plate of the third unit is used to limit the other side of the hard disk fixing device. A partition group can install two hard disk fixing devices, and the first straight plate and the third straight plate of the second unit play a limiting role for both hard disk fixing devices. At the same time, since the first straight plate and the third straight plate are parallel and separated, the third straight plate of the first unit and the third straight plate of the second unit can enlarge the opening of the hard disk fixing device entering the partition group, thereby facilitating the hard disk fixing device to be inserted into the hard disk fixing frame.

[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, the locking handle is rotated. Since the hard disk hook is arranged on the side of the hinge axis away from the locking handle, 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 limiting 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 also includes a locking button, which is arranged on a side of the mounting block away from the hinge axis, and the locking button is hinged to the mounting block; the locking block also includes a locking boss, which is arranged on a 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 close to the side of the mounting block.

[0089] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0090] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0091] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centrally disposed element at the same time. When an element is considered to be "disposed" on another element, it may be directly disposed on the other element or there may be a centrally disposed element at the same time.

[0092] Unless otherwise clearly specified and limited, terms such as "installation", "connection", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium.

[0093] For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0094] The embodiment of the present application provides a hard disk fixing device, comprising a sliding bracket, a hard disk bracket and an elastic member. The sliding bracket is used to fix the hard disk body, and the sliding bracket is slidably arranged on the hard disk bracket along a first direction, so as to plug the plug-in of the hard disk body into the connector of the backplane module along the first direction. The elastic member is arranged 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.

[0095] In the above embodiment, the sliding bracket is used to fix the hard disk body, and the sliding bracket drives the plug-in of the hard disk body to slide on the hard disk bracket along the first direction and is used to plug the connector of the backplane module, so that the hard disk body has a movable space, thereby improving the problem that the hard disk body interferes with and is inconvenient to install due to the tolerance accumulated in manufacturing and assembly. The first direction refers to the direction in which the connection port of the hard disk body faces the backplane module and docks with the backplane module. The elastic member is arranged between the sliding bracket and the hard disk fixing device, and the elastic member can drive the sliding bracket to slide along the first direction, so that when the hard disk fixing device is docked with the backplane module, the hard disk body installed on the hard disk fixing device always has a pressing force pressed against the backplane module. The sliding bracket slidingly arranged on the hard disk bracket can absorb the accumulated tolerance, and the elastic member can press the hard disk body against the backplane module to eliminate the influence of the gap between the hard disk body and the backplane module on the connection between the hard disk body and the backplane module, thereby improving the problem of poor signal transmission between the hard disk fixing device and the backplane module.

[0096] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the features in the following embodiments and examples can be combined with each other.

[0097] See also Figure 1Some embodiments of the present application provide a chassis 100, including a housing 10, a backplane module 20, a hard disk fixing frame 30, and a plurality of hard disk fixing devices 40. The housing 10 includes a bottom housing 12 and a top cover 11, a fixing cavity 13 is formed between the bottom housing 12 and the top cover 11, and the backplane module 20 and the hard disk fixing frame 30 are both fixed in the fixing cavity 13 of the housing 10, so that the backplane module 20 and the hard disk fixing frame 30 are protected by the housing 10. Among them, the hard disk fixing frame 30 is located at one end of the fixing cavity 13, so that it is convenient to install the hard disk fixing device 40 to the hard disk fixing frame 30.

[0098] The backplane module 20 is located at the side of the hard disk fixing frame 30, and a plurality of hard disk fixing devices 40 are installed on the hard disk fixing frame 30 along the first direction X. The hard disk fixing device 40 is used to install a hard disk body 41, and the hard disk body 41 includes a plug-in component 411 and a storage medium 412 electrically connected to the plug-in component 411. The plug-in component 411 is used to electrically connect the backplane module 20, and the first direction X refers to the direction in which the hard disk fixing frame 30 faces the backplane module 20, so that the hard disk fixing device 40 can directly dock with the backplane module 20.

[0099] In some embodiments, the backplane module 20 includes a mounting backplane 21 and a plurality of connectors 22, wherein the plurality of connectors 22 are evenly arranged and fixed to the side of the mounting backplane 21 along a second direction Y so as to facilitate docking with the connector 411 of the hard disk body 41 in the hard disk fixing device 40. The second direction Y is perpendicular to the first direction X.

[0100] See also Figure 2 In some embodiments, the hard disk fixing frame 30 includes a fixed bottom plate 31 and a fixed top plate 32, the fixed bottom plate 31 and the fixed top plate 32 enclose a mounting cavity 33 with openings at both ends along the first direction X, and the hard disk fixing device 40 is installed in the hard disk fixing frame 30 along the first direction X. The side surfaces of the hard disk fixing device 40 in the width direction are respectively attached to the fixed bottom plate 31 and the fixed top plate 32, so that the hard disk fixing device 40 can be slidably installed to the hard disk fixing frame 30 along the first direction X.

[0101] In some embodiments, a plurality of partition plates 34 are provided in the hard disk fixing frame 30, and the partition plates 34 are detachably fixed between the fixed top plate 32 and the fixed bottom plate 31, so as to divide the installation cavity 33 into a plurality of areas. On the one hand, each area is heat-insulated to improve the problem of heat accumulation. On the other hand, by partitioning the installation cavity 33, the hard disk fixing device 40 inserted into the corresponding area can be classified and managed, thereby improving the convenience of identifying the hard disk fixing device 40.

[0102] In some embodiments, two partition plates 34 are disposed in the hard disk mounting bracket 30 , thereby dividing the mounting cavity 33 into three areas.

[0103] See also Figure 2 In some embodiments, a plurality of partitions 311 are disposed on the inner bottom surface of the fixed bottom plate 31, so as to install the hard disk fixing device 40 between two adjacent partitions 311. The plurality of partitions 311 are evenly spaced along the second direction Y, so that the plurality of hard disk fixing devices 40 can be installed side by side on the hard disk fixing frame 30 along the second direction Y, thereby improving the installation stability of the hard disk fixing device 40.

[0104] In some embodiments, a retaining boss 312 is provided on the fixed 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 fixing device 40 to limit the position of the hard disk fixing device 40 on the fixed base plate 31, the retaining boss 312 corresponding to the partition 311 stops the side of the hard disk fixing device 40, thereby further improving the installation stability of the hard disk fixing device 40.

[0105] In some embodiments, the separator 311 and the flange boss 312 are both formed by sheet metal stamping to improve the processing convenience of the separator 311 and the flange boss 312. Specifically, the fixed base plate 31 is formed by a piece of sheet metal stamping, and when the separator 311 and the flange boss 312 are formed on the fixed base plate 31. Forming holes are formed at positions corresponding to the separator 311 and the flange boss 312 on the fixed base plate 31. The shapes of these forming holes are equivalent to the separator 311 or the flange boss 312, and the forming holes are connected to the outside of the installation cavity 33 to improve the heat dissipation effect of the installation cavity 33. This form of forming the separator 311 and the flange boss 312 by sheet metal stamping, on the one hand, is convenient for the processing of the separator 311 and the flange boss 312, and reduces the processing cost. On the other hand, the forming holes generated when the separator 311 and the flange boss 312 are formed can also improve the heat dissipation performance of the installation cavity 33 formed by the hard disk fixing frame 30.

[0106] In some embodiments, each partition 311 and each flange boss 312 are provided with flange strips 313 along the third direction Z, and the third direction Z is respectively perpendicular to the first direction X and the second direction Y, and is directed from the fixed bottom plate 31 to the fixed top plate 32. The flange strips 313 are provided on the bottom surface of the fixed top plate 32, and the flange strips 313 are used to cooperate with the corresponding partition 311, so as to stop the other side of the hard disk fixing device 40 in the third direction Z, thereby further improving the installation stability of the hard disk fixing device 40.

[0107] In some embodiments, the sidewall strip 313 is formed by sheet metal stamping to improve the processing convenience of the sidewall strip 313 .

[0108] See also Figure 2 and Figure 3In some embodiments, at least three separators 311 are provided. The separators 311 include a first straight plate 3111, a second straight plate 3112, and a third straight plate 3113. The first straight plate 3111 is parallel to the third straight plate 3113 and has a separation distance. Two ends of the second straight plate 3112 are respectively connected to the first straight plate 3111 and the third straight plate 3113. 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.

[0109] Three adjacent partitions 311 form a partition group 310, so that the arrangement of each partition 311 is the same, and all the partitions 311 can be processed in the same way, thereby improving the processing efficiency of the partitions 311 and reducing the processing cost. In a partition group 310, along the second direction Y, the partition 311 at one end is the first unit 3101, the partition 311 in the middle is the second unit 3102, and the partition 311 at the other end is the third unit 3103.

[0110] The third straight plate 3113 of the first unit 3101 is used to limit one side of the first hard disk fixing 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 fixing device 40; the third straight plate 3113 of the second unit 3102 is used to limit one side of the second hard disk fixing 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 fixing device 40. One set of partitioning group 310 can be installed with two hard disk fixing devices 40, and the first straight plate 3111 and the third straight plate 3113 of the second unit 3102 play a limiting role for the hard disk fixing devices 40 on both sides. At the same time, the first straight plate 3111 and the third straight plate 3113 are parallel and separated, so 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 of the hard disk fixing device 40 entering the partition group 310, and the second plate 312 of the second unit 3102 can guide the hard disk fixing device 40 into the partition group 310, thereby facilitating the hard disk fixing device 40 to be inserted into the hard disk fixing bracket 30.

[0111] On the one hand, 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, thereby 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 separate sheet metal stamping. Since each partition 311 has the same shape, and a hard disk fixing device 40 can be installed between every two adjacent partitions 311. Compared with setting spaced clamping components on the fixed base plate 31, by clamping a hard disk fixing device 40 with each clamping component, the gap between the clamping components can be omitted, thereby improving the space utilization of the fixed base plate 31.

[0112] In some embodiments, a plurality of locking grooves 314 are further provided on the inner bottom surface of the fixed base plate 31 , and the locking grooves 314 face the openings of the partition group 310 , so that after the hard disk fixing device 40 is installed on the hard disk fixing bracket 30 , the position can be locked through the locking grooves 314 .

[0113] See also Figure 4 and Figure 5 , some embodiments of the present application also provide a hard disk fixture 40 for installing a hard disk body 41. Due to the accumulated tolerances of the hard disk fixture 40 during the manufacturing and assembly process, if the hard disk fixture 40 is directly connected to the backplane template 20, there is a problem that the hard disk fixture 40 cannot be installed due to insufficient installation space. If the installation space of the hard disk fixture 40 is hastily increased, there will be a gap between the hard disk body 41 on the hard disk fixture 40 and the backplane template 20 due to vibration during transportation, resulting in unstable signal transmission.

[0114] In some embodiments, the hard disk fixing 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 plug-in 411 and a storage medium 412 electrically connected to the plug-in 411, and the plug-in 411 is used to electrically connect the connector 22. The hard disk body 41 is fixed to the sliding bracket 42, and the sliding bracket 42 is slidingly arranged on the hard disk bracket 43 along the first direction X, driving the hard disk body 41 to slide along the first direction X, so that the hard disk body 41 has a movable space, thereby improving the problem of interference and inconvenience in installation of the hard disk body 41 caused by the accumulated tolerances in manufacturing and assembly. The elastic member 44 is arranged between the sliding bracket 42 and the hard disk fixing device 40, and the elastic member 44 has a pressing force to drive the sliding bracket 42 to slide along the first direction X. The hard disk body 41 slidably arranged on the hard disk bracket 43 can absorb the accumulated tolerance, and the elastic member 44 can press the hard disk body 41 against the backplane module 20 to eliminate the influence of the gap between the hard disk body 41 and the backplane module 20 on the connection between the hard disk fixing device 40 and the backplane module 20, thereby improving the problem of poor signal transmission between the hard disk fixing device 40 and the backplane module 20.

[0115] See also Figure 5 and Figure 6 In some embodiments, the hard disk fixing device 40 further includes a stop plate 45 and a positioning post 46. The positioning post 46 is fixed to the side wall of the sliding bracket 42 facing the stop plate 45, and the stop plate 45 is fixed to the inner wall of the hard disk bracket 43. The stop plate 45 is provided with a through hole 451, and the positioning post 46 passes through the through hole 451. 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 stop plate 45, and the elastic member 44 is sleeved on the outer circumferential surface of the positioning post 46, so that the positioning post 46 can constrain the position of the elastic member 44, thereby improving the problem of unstable position of the elastic member 44 during deformation.

[0116] In some embodiments, the baffle plate 45 is integrally formed on the hard disk bracket 43 by bending sheet metal, thereby facilitating the forming of the baffle plate 45. In other embodiments, the baffle plate 45 can also be fixed to the hard disk bracket 43 by welding, bolting, etc.

[0117] In some embodiments, the positioning column 46 is fixed to the side wall of the sliding bracket 42 by riveting to improve the installation convenience of the positioning column 46.

[0118] In some embodiments, the elastic member 44 is configured as a compression spring, one end of which is pressed against the side wall of the sliding bracket 42, and the other end of which is pressed against the retaining plate 45, thereby improving installation convenience. In other embodiments, the elastic member 44 can also be configured in other forms, for example, the elastic member 44 can also be configured as a pair of mutually repelling magnetic members.

[0119] See also Figure 5 and Figure 6 In some embodiments, the hard disk fixing device 40 also includes a limit member 47, which is disposed between the hard disk bracket 43 and the sliding bracket 42. The limit member 47 is used to stop the sliding bracket 42 sliding along the first direction X on the hard disk bracket 43 to limit the sliding range of the sliding bracket 42 along the first direction X, thereby improving the problem of the sliding bracket 42 driving the hard disk body 41 to detach from the hard disk bracket 43, and improving the installation convenience of the hard disk body 41.

[0120] 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. The side wall of the sliding bracket 42 is provided with a limiting opening 421, the length direction of the limiting opening 421 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.

[0121] In some embodiments, the limiting post 471 is fixedly connected to the side wall of the hard disk bracket 43 by riveting, the limiting opening 421 is formed into a rectangular cutout by punching, and the limiting post 471 is fixed to the side wall of the hard disk bracket 43 and is partially located in the limiting opening 421. The fixing method of the limiting post 471 and the hard disk bracket 43 is simple, and the processing method of the limiting opening 421 is simple. Through the cooperation of the limiting post 471 and the limiting opening 421, the processing cost can be reduced while realizing the limiting function, and the space utilization rate of the hard disk fixing device 40 is improved.

[0122] In some embodiments, the limiting member 47 is a pair of limiting nuts, which are respectively threadedly connected to the outer circumferential surface of the positioning column 46, and one limiting nut is located on one side of the retaining plate 45, and the other limiting nut is located on the other side of the retaining plate 45. The maximum outer diameter of the limiting nut is greater than the diameter of the through hole 451, so that the retaining plate 45 can stop the positioning column 46 on which the limiting nut is installed, thereby limiting the sliding range of the sliding bracket 42 along the first direction X.

[0123] In some embodiments, the distance between the two limiting nuts and the retaining plate 45 is determined, and the limiting nuts are locked in position by semi-permanent thread locking adhesive, so as to improve the position stability of the limiting nuts, thereby improving the position stability of the sliding bracket 42. Semi-permanent thread locking adhesive refers to a thread adhesive that can fill the gaps between the threads to prevent the bolts from loosening, and can help the bolts resist vibration and impact, and can be broken by tools when disassembly is required.

[0124] See also Figure 4 and Figure 5Combined with Figure 1 In some embodiments, the hard disk fixing device 40 further includes a heat dissipation bar 48, which is fixed to the inner wall of the hard disk bracket 43 and contacts the side of the hard disk body 41. The side of the heat dissipation bar 48 is integrally provided with a heat-conducting column 481, which can be pressed against the fixed top plate 32, so that when the hard disk body 41 is working and generates heat accumulation, the heat dissipation bar 48 can absorb the heat of the hard disk body 41, improve the problem of performance degradation or storage structure damage of the hard disk body 41 due to heat accumulation, and increase the service life of the hard disk body 41.

[0125] In some embodiments, two heat dissipation bars 48 are provided, and the two heat dissipation bars 48 are arranged vertically and parallelly on the side of the hard disk bracket 43 to improve the heat dissipation performance of the hard disk fixing device 40 .

[0126] See also Figure 7 and Figure 8 In some embodiments, the hard disk fixing device 40 further includes a locking assembly 49, which is disposed on the side of the hard disk bracket 43 facing the opposite direction of the first direction X. The locking assembly 49 includes a mounting block 491 and a locking block 492, wherein the mounting block 491 is fixed to the side of the hard disk bracket 43 by bolts, and the locking block 492 is hinged to the mounting block 491, and the hinge between the locking block 492 and the mounting block 491 has a hinge axis. The locking block 492 includes a locking handle 4921 and a hard disk hook 4922, wherein the hard disk hook 4922 is located on the side of the hinge axis away from the locking handle 4921, so that the locking handle 4921 and the hard disk hook 4922 have opposite rotation directions. When the locking block 492 is parallel to the mounting block 491, the hard disk hook 4922 is located in the locking groove 314, so that the side wall of the locking groove 314 stops the hard disk hook 4922, thereby limiting the position of the hard disk fixing device 40 and improving the installation convenience of the hard disk fixing device 40.

[0127] See also Figure 7 and Figure 8 Combined with Figure 1In some embodiments, the locking assembly 49 further includes a locking button 493, which is disposed on a side of the mounting block 491 away from the hinge axis, and 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 middle of the mounting block 491. The locking block 492 further includes a locking boss 4923, which is disposed on a 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 is close to the side of the mounting block 491 to stop the locking boss 4923, and the locking boss 4923 is located obliquely 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, so that the side wall of the locking slot 314 stops the hard disk hook 4922, and limits the position of the hard disk fixing device 40.

[0128] In some embodiments, a torsion spring 494 is provided at the hinge of the locking block 492 and the mounting block 491, which is used to drive the locking block 492 to rotate so that the locking boss 4923 has a driving force to move 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 convenience of disassembly and assembly of the hard disk fixing device 40.
