Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a hard disk bracket, a hard disk assembly and an electronic device. Background Art

[0002] In servers, as users' demand for replacing and repairing hard drive assemblies increases, removable hard drive assemblies are becoming more widely used. These assemblies are installed and removed from the chassis of electronic devices through plugging and unplugging. The hard drive assembly is locked and unlocked with the chassis by a retaining assembly in the hard drive bracket. Current retaining assemblies in hard drive brackets have complex structures and high costs. Summary of the Invention

[0003] The present application provides a hard disk bracket, a hard disk assembly and an electronic device. The hard disk bracket has a limiting assembly with fewer components, a simple structure and low cost.

[0004] In a first aspect, the present application provides a hard drive bracket, which is used for a removable hard drive assembly, and the hard drive assembly is installed or removed from the chassis by plugging and unplugging. The hard drive bracket includes a base, a handle, and a dial key. The handle is located on one side of the base, and the handle rotates to connect to the base. The dial key is located on the side of the base where the handle is provided, and the dial key slides to connect to the base. The hard drive bracket has a locked state and an unlocked state. When the hard drive bracket is in the locked state, the dial key presses against the handle; when the hard drive bracket is in the unlocked state, the dial key is disengaged from the handle.

[0005] In this application, the dial key is used to control the locking and unlocking of the handle. Compared to the complex limit assembly structure of the hard drive bracket in the prior art, this embodiment can quickly unlock the handle by simply sliding the dial key. The limit assembly used to control the locking and unlocking of the hard drive assembly in the hard drive bracket has fewer components, a simpler structure, and easy assembly between the components, resulting in a lower manufacturing cost for the hard drive bracket.

[0006] In some possible implementations, the handle includes a locking portion, a rotating portion, and a snap-fit portion, the rotating portion being positioned between the locking portion and the snap-fit portion, the rotating portion being rotatably connected to the base, and the dial key including a locking tongue portion and a sliding portion, the sliding portion being slidably connected to the base, so that the hard drive bracket can have a locked state and an unlocked state. When the hard drive bracket is in the locked state, the locking tongue portion abuts against the locking portion, the rotating portion cannot rotate relative to the base, and the snap-fit portion is configured to snap into the chassis to secure the hard drive assembly to the chassis. When the hard drive bracket is in the unlocked state, the locking tongue portion disengages from the locking portion, the rotating portion can rotate relative to the base, and the snap-fit portion disengages from the chassis, allowing the hard drive assembly to be removed from the chassis.

[0007] In the present application, the rotating portion of the handle is rotatably connected to the base, and the rotating portion is located between the locking portion and the engaging portion, so that the locking portion and the engaging portion can rotate around the rotating portion, thereby achieving that the locking portion can be away from the base and the engaging portion can be close to the base, or the locking portion can be close to the base and the engaging portion can be away from the base. The sliding portion of the dial key cooperates with the base to achieve that the dial key can be close to or away from the handle. The locking portion of the handle cooperates with the lock tongue portion of the dial key to control the dial key to resist or disengage from the handle. Furthermore, the rotating portion of the handle can rotate relative to the base, driving the engaging portion to move closer to or away from the base, thereby achieving the locking and unlocking of the hard disk bracket. Therefore, the dial key, the handle and the base constitute a limiting assembly of the hard disk bracket, which is used to control the locking and unlocking between the hard disk assembly and the chassis.

[0008] In some possible implementations, the base includes a first side wall, a second side wall and a third side wall, the first side wall and the second side wall are arranged opposite to each other, the third side wall is connected between the first side wall and the second side wall, and the hard disk bracket also includes a first elastic member, the first elastic member is located between the dial key and the third side wall, the first elastic member is in a compressed state to generate a first elastic force, and the first elastic force is used to drive the dial key close to the handle.

[0009] In the present application, the dial button can automatically rebound under the action of the first elastic member without applying external force, and the locking operation of the hard disk bracket is simpler.

[0010] In some possible implementations, the dial key further includes a body, the sliding portion includes a first slider and a second slider, the first slider and the second slider are both fixed to the body and spaced apart, the first slider is slidably connected to the first side wall, and the second slider is slidably connected to the second side wall.

[0011] In some possible implementations, the sliding portion further includes a first limit block, which is fixed to the main body; the first side wall includes a first slide groove, the first limit block is engaged in the first slide groove, and can slide in the first slide groove, and the first limit block is used to prevent the dial key from detaching from the base; and / or, the sliding portion further includes a second limit block, which is fixed to the main body; the second side wall includes a second slide groove, the second limit block is engaged in the second slide groove, and can slide in the second slide groove, and the second limit block is used to prevent the dial key from detaching from the base.

[0012] In the present application, the first slider is slidably connected to the first side wall, and the second slider is slidably connected to the second side wall, allowing the dial key to move upward relative to the base in the first direction X. This allows the sliding portion to slidably connect the first side wall and the second side wall, thereby slidably connecting the dial key to the base. In addition, the first slide groove limits the first limit block of the dial key, and the second slide groove limits the second limit block of the dial key, ensuring smooth and reliable sliding of the dial key relative to the base.

[0013] In some possible implementations, the dial key further includes a blocking portion, which is arranged facing the third side wall; the hard disk bracket further includes a first elastic member, which is located between the blocking portion and the third side wall and elastically supports the blocking portion and the third side wall.

[0014] In the present application, the blocking portion and the third side wall limit the first elastic member, so that the first elastic member elastically abuts against the blocking portion of the dial key and the third side wall of the base, so that the first elastic member generates a first elastic force on the dial key.

[0015] In some possible implementations, the rotating portion rotatably connects the first side wall and the second side wall.

[0016] In the present application, the rotating portion of the handle is rotatably connected to the first side wall and the second side wall of the base, so that the connection between the handle and the base is more stable.

[0017] In some possible implementations, the handle also includes a supporting portion, the center of the supporting portion is located between the rotating portion and the locking portion, and the hard disk bracket also includes a second elastic member, which abuts between the supporting portion and the base; when the hard disk bracket is in a locked state, the second elastic member is in a compressed state, generating a second elastic force; when the hard disk bracket is in an unlocked state, the second elastic force pushes the handle to rotate so that the locking portion is away from the base.

[0018] In the present application, under the action of the second elastic member, the first end of the handle can automatically rotate around the rotating part toward the side away from the base without applying external force, making the unlocking operation of the hard disk bracket simpler.

[0019] In some possible implementations, the hard disk bracket further includes a bracket and a light guide, the bracket is fixed to the side of the base away from the handle, the light guide is fixed to the bracket, and the light guide extends from the side of the bracket away from the base to the dial key.

[0020] In some possible implementations, one end of the light guide is embedded in the dial key. When the dial key is separated from the handle, the light guide presses against the dial key to generate a third elastic force, which is used to drive the dial key closer to the handle.

[0021] In the present application, one end of the light guide is embedded within the dial key, restricting its upward movement in the first direction X. The plastic light guide also has a certain degree of elasticity. When the blocking plate of the dial key abuts the light guide, the light guide exerts a third elastic force on the blocking plate, pushing the dial key toward the handle. Without applying external force, the dial key automatically rebounds, returning to its initial position when the hard drive bracket is locked.

[0022] In some possible implementations, the bracket includes a first side panel, a second side panel and a third side panel, the first side panel and the second side panel are arranged opposite to each other, the third side panel is connected between the first side panel and the second side panel, and the third side panel is connected to the base; the light guide is provided with a first clamping portion, and the first clamping portion is clamped to the first side panel.

[0023] In some possible implementations, the light guide is provided with a second clamping portion, which is spaced apart from the first clamping portion and clamps the first side plate; the limiting direction of the first side plate on the second clamping portion is different from the limiting direction on the first clamping portion.

[0024] In the present application, in this embodiment, the light guide can be installed on the first side plate of the bracket through the first clamping portion and the second clamping portion. The first side plate limits the first clamping portion of the light guide in the second direction Y upward and the first direction X upward, and is opposite to the limiting direction of the second clamping portion of the light guide by the first side plate. A clamping connection is formed between the light guide and the first side plate, so that the fixation of the light guide to the bracket is more stable, and the light guide can be prevented from being displaced relative to the bracket due to external force.

[0025] In some possible implementations, the light guide includes a first light guide bar and a second light guide bar, the first light guide bar and the second light guide bar are arranged at intervals, the first clip is fixed between the first light guide bar and the second light guide bar, the first light guide bar and / or the second light guide bar is provided with at least one second clip, and the second clip is arranged facing the first side panel.

[0026] In some possible implementations, the first side panel is provided with a snap-fitting member, which includes a connecting plate and a snap-fitting plate. The snap-fitting plate is arranged opposite to the first side panel, the connecting plate is connected between the snap-fitting plate and the first side panel, the first snap-fitting portion snaps into the snap-fitting member, and the first snap-fitting portion abuts against the connecting plate.

[0027] In some possible implementations, the first side plate is further provided with at least one engaging groove, the engaging groove and the engaging member are spaced apart, the second engaging portion engages the engaging groove, and the limiting direction of the engaging member on the first engaging portion is opposite to the limiting direction of the engaging groove on the second engaging portion.

[0028] In the present application, the engaging member of the first side panel limits the light guide member in the second direction Y upward and in the first direction X upward, and the engaging member and the engaging groove limit the light guide member in opposite directions. A snap connection is formed between the light guide member and the first side panel, so that the fixation of the light guide member to the bracket is more stable, and the light guide member can be prevented from being displaced relative to the bracket due to external force.

[0029] In some possible implementations, the hard disk bracket also includes a bracket, the bracket includes a first side panel, a second side panel and a third side panel, the first side panel and the second side panel are arranged opposite to each other, the third side panel is connected between the first side panel and the second side panel, and the third side panel is connected to the base; the first side panel is provided with at least one first spring plate, and the first spring plate protrudes toward the outside of the bracket relative to the first side panel.

[0030] In this application, when the hard drive assembly is installed in the server chassis, the first spring clip is compressed between the chassis and the first side panel, and the second spring clip is compressed between the chassis and the second side panel. The first and second spring clips are located in the gap between the chassis and the bracket, providing support and shock absorption for the bracket. This helps improve the hard drive assembly's seismic resistance at different vibration frequencies, resulting in stronger seismic performance and higher hard drive operational reliability. Furthermore, the provision of the first and second spring clips helps enhance the structural strength of the first and second side panels.

[0031] In some possible implementations, the bracket also includes a bottom plate, which is located between the first side plate and the second side plate. The bottom plate includes a first bottom plate and a second bottom plate, and the first bottom plate and the second bottom plate are spaced apart. The first bottom plate is connected to the first side plate, and the second bottom plate is connected to the second side plate. The first bottom plate is provided with a plurality of first sink grooves, and the plurality of first sink grooves all protrude relative to the first bottom plate toward the side away from the first side plate.

[0032] In this application, the bracket's base plate is provided with a first recessed groove and a second recessed groove, which enhances the base plate's structural strength. Furthermore, the first recessed groove protrudes from the side of the first base plate facing away from the first side plate, while the second recessed groove protrudes from the side of the second base plate facing away from the second side plate. These first and second recessed grooves prevent the protruding portion of the base plate from scraping against other components when the first fixing member is mounted on the base plate, thereby preventing the generation of metal debris.

[0033] In some possible implementations, one of the first side panel or the second side panel is provided with an avoidance notch, and the avoidance notch is located at an end of the bracket facing away from the base.

[0034] In this application, the provision of an avoidance notch on the bracket can prevent the hard disk assembly from being installed incorrectly, reducing the risk of damage to the hard disk assembly during insertion.

[0035] In some possible implementations, the bracket is an integrally formed sheet metal part, and the thickness of the sheet metal part is in the range of 0.2 mm to 1.5 mm.

[0036] In this application, the bracket is a one-piece sheet metal component. When the sheet metal component is 0.3 mm thick, the bracket's dimension in the first direction (X) is minimal, minimizing the space occupied by the entire hard drive assembly. Given a standardized server chassis size, more hard drive assemblies according to this embodiment can be configured within the chassis, helping to increase the server's computing speed and storage capacity.

[0037] In a second aspect, the present application also provides a hard disk assembly, which includes a hard disk and any of the hard disk brackets described above, wherein the hard disk is installed on the inner side of the hard disk bracket.

[0038] In a third aspect, the present application further provides an electronic device, which includes a chassis and the above-mentioned hard disk assembly, and the hard disk assembly is installed in the chassis. BRIEF DESCRIPTION OF THE DRAWINGS

The supporting portion 25 is fixed to the main body 21. Exemplarily, the supporting portion 25 may be protruding relative to the main body 21, and be located on the same side of the main body 21 as the rotating portion 23. Exemplarily, a positioning column 251 is provided at the center of the supporting portion 25. The supporting portion 25 may be a structural member integrally formed with the main body 21. In some other embodiments, the supporting portion 25 may also be embedded in the main body 21, and the supporting portion 25 is formed by a partial structure of the main body 21, and the supporting portion 25 is exposed relative to the accommodating space 215. The supporting portion 25 is used to install and limit the second elastic member 5.

Exemplarily, the ventilation hole 216 can be a strip-shaped hole, and the area occupied by the ventilation hole 216 on the exterior surface of the main body 21 is at least half of the area of the exterior surface of the main body 21. The exterior surface of the main body 21 is the surface of the side of the main body 21 facing the second direction Y. In this embodiment, the main body 21 is provided with a larger ventilation hole 216, which increases the ventilation rate of the hard disk bracket 10, and the hard disk 20 (see Figure 2B ) can be transferred to the outside of the hard disk bracket 10 through the ventilation holes 216 of the handle 2, which helps to improve the heat dissipation capacity of the hard disk assembly 100 using the hard disk bracket 10.

[0082] In some other embodiments, the ventilation holes 216 may also be of other shapes, or the main body 21 may not be provided with ventilation holes 216, which is not strictly limited in this application.

[0083] See also Figure 7 , Figure 7 yes Figure 3 The partial structural diagram of the hard disk bracket 10 is shown in FIG1. Figure 7 In the embodiment, the handle 2 is installed on a side of the base 1 facing the second direction Y.

[0084] Please refer to Figure 5A 、 Figure 5B 、 Figure 6B and Figure 8 , Figure 8 yes Figure 7 The structure shown is a schematic diagram of the cross-section taken along AA.

[0085] In some embodiments, the handle 2 is mounted on one side of the base 1. The rotating portion 23 of the handle 2 is rotatably connected to the first side wall 11 and the second side wall 12 of the base 1. The first rotating column 231 is rotatably mounted on the first mounting hole 113, and the second rotating column 232 is rotatably mounted on the second mounting hole 123. The engaging portion 24 protrudes relative to the base 1 toward the side away from the first mounting hole 113. The end of the first rotating column 231 facing the first side wall 11 is provided with an oblique pin-shaped end surface to facilitate the first rotating column 231 to be snapped into the first mounting hole 113. The end of the second rotating column 232 facing the second side wall 12 is provided with an oblique pin-shaped end surface to facilitate the second rotating column 232 to be snapped into the second mounting hole 123.

[0086] In this embodiment, the rotating portion 23 of the handle 2 is rotatably connected to the first side wall 11 and the second side wall 12 of the base 1, making the connection between the handle 2 and the base 1 more stable. In addition, the rotating portion 23 is located between the locking portion 22 and the engaging portion 24, so that the locking portion 22 and the engaging portion 24 can rotate about the rotating portion 23, thereby enabling the locking portion 22 to move away from the base 1 and the engaging portion 24 to move closer to the base 1, or vice versa.

[0087] In other embodiments, the first rotating post 231 may be disposed on the first sidewall 11 of the base 1, and the second rotating post 232 may be disposed on the second sidewall 12 of the base 1, with the first rotating post 231 and the second rotating post 232 located between the first sidewall 11 and the second sidewall 12. The first mounting hole 113 and the second mounting hole 123 are respectively disposed on the first connecting arm 212 and the second connecting arm 213 of the handle 2. A rotational connection between the handle 2 and the base 1 may also be achieved by mating the first rotating post 231 with the first mounting hole 113 and the second rotating post 232 with the second mounting hole 123, although this is not strictly limited in this application.

[0088] In some embodiments, the locking portion 22 of the handle 2 is installed in the first accommodating space 114 and / or the second accommodating space 124 of the base 1. The shape of the first accommodating space 114 and / or the second accommodating space 124 is adapted to the shape of the locking portion 22. Exemplarily, the first accommodating space 114 and the second accommodating space 124. Exemplarily, when the handle 2 includes two locking portions 22, the two locking portions 22 are respectively installed in the first accommodating space 114 and the second accommodating space 124 of the base 1. When the handle 2 includes one locking portion 22, the locking portion 22 is installed in the first accommodating space 114 or the second accommodating space 124.

[0089] Please refer to Figures 9A to 10 , Figure 9A yes Figure 4 The structure diagram of the dial key 3 in some embodiments is shown. Figure 9B yes Figure 9A The structure diagram of the dial key 3 shown is from another angle.

[0090] In some embodiments, the dial key 3 is located on the side of the base 1 where the handle 2 is provided. The dial key 3 may include a body 31, a lock tongue portion 32, and a toggle portion 33. The toggle portion 33 and the lock tongue portion 32 are both fixed to the body 31 and are located at both ends of the body 31. The toggle portion 33 protrudes relative to the body 31 toward the side away from the base 1. Exemplarily, the toggle portion 33 may be a rectangular parallelepiped, and an indicator mark 331 may be provided on the side of the toggle portion 33 away from the body 31. The indicator mark 331 can be used to indicate the direction in which the dial key 3 is unlocked, so as to facilitate the user to determine the direction in which the dial key 3 is to be toggled when unlocking. The indicator mark 331 may be a pattern, a protrusion, a groove or other structure, which is not strictly limited in the embodiments of the present application.

[0091] The body 31 of the dial key 3 may be a plate structure, and the body 31 may be provided with an opening, so that the body 31 is generally "U" shaped. In this embodiment, the body 31 is provided with an opening, which increases the ventilation rate of the hard disk bracket 10, and the hard disk 20 (see Figure 2B ) can be transferred to the outside of the hard disk bracket 10 through the opening of the dial key 3, which helps to improve the heat dissipation capacity of the hard disk assembly 100 using the hard disk bracket 10.

[0092] In some other embodiments, the main body 31 of the dial key 3 may not be provided with an opening, and this application does not impose a strict limitation on this.

[0093] In some embodiments, the locking tongue portion 32 may be a plate structure and include a supporting surface 321 and a sliding surface 322. The supporting surface 321 faces the base 1. The sliding surface 322 may be a slanted pin-shaped end surface. An installation space 311 is formed between the supporting surface 321 and the end surface of the body 31 facing away from the toggle portion 33.

[0094] Please participate Figure 10 , Figure 10 yes Figure 3 The second schematic diagram of the partial structure of the hard disk bracket 10 is shown. Figure 10 In the embodiment, the handle 2 and the dial key 3 are installed on one side of the base 1 facing the second direction Y, and the dial key 3 is used to control the locking and unlocking of the handle 2.

[0095] Please refer to Figure 9A 、 Figure 9B 、 Figure 11 and Figure 12 , Figure 11 yes Figure 10 The structure shown is a schematic diagram of the cross-section taken along BB. Figure 12 yes Figure 10 The structure shown is a schematic diagram of the structure at another angle along the cross section of CC. It should be noted that, Figure 12 To clearly show Figure 10 The structure shown is a schematic diagram of the cross section of the structure cut along CC. Figure 10 The components in the image are rotated by a certain angle.

[0096] In some embodiments, the dial key 3 may further include a sliding portion 34 that is slidably connected to the base 1. The sliding portion 34 may include a first sliding portion 341 and a second sliding portion 342. The first sliding portion 341 and the second sliding portion 342 are disposed opposite each other and are both fixed to the body 31. The first sliding portion 341 may include a first cantilever 3411 and a first stopper 3412. The second sliding portion 342 may include a second cantilever 3421 and a second stopper 3422. The first cantilever 3411 and the second cantilever 3421 are both fixed to the body 31 and spaced apart. For example, the first cantilever 3411 and the second cantilever 3421 may be disposed opposite each other. The first cantilever 3411 and the second cantilever 3421 face the first side wall 11 and the second side wall 12 of the base 1, respectively. The first stopper 3412 is fixed to the first cantilever 3411 and faces the first side wall 11. The second stopper 3422 is fixed to the second side wall 12 and faces the second side wall 12. The first limiting block 3412 is slidably connected to the first side wall 11 , and the second limiting block 3422 is slidably connected to the second side wall 12 .

[0097] The first stopper 3412 is inserted into the first chute 111 and is capable of sliding relative to the first chute 111. A slanted pin-shaped end surface is provided on the side of the first stopper 3412 facing the first sidewall 11 to facilitate smooth insertion of the first stopper 3412 into the first chute 111. Exemplarily, in the first direction X, the size of the first stopper 3412 is smaller than the size of the first chute 111 to facilitate sliding of the first stopper 3412 within the first chute 111. The second stopper 3422 is mounted on the second chute 121 and is capable of sliding relative to the second chute 121. A slanted pin-shaped end surface is provided on the side of the second stopper 3422 facing the second sidewall 12 to facilitate smooth insertion of the second stopper 3422 into the second chute 121. Exemplarily, in the first direction X, the size of the second stopper 3422 is smaller than the size of the second chute 121 to facilitate sliding of the second stopper 3422 within the second chute 121. At the same time, the first sliding groove 111 and the second sliding groove 121 can respectively limit the upward movement of the first limiting block 3412 and the second limiting block 3422 in the first direction X.

[0098] In this embodiment, the body 31 abuts the base 1, and the first stopper 3412 and second stopper 3422 of the dial key 3 respectively engage the first slot 111 and second slot 121 of the base 1, so that the dial key 3 and the base 1 are mutually restrained in the second direction Y. The dial key 3 can only slide relative to the base 1 in the first direction X. The first stopper 3412 and second stopper 3422 are used to prevent the dial key 3 from being separated from the base 1.

[0099] In some embodiments, the first sliding portion 341 may further include a first slider 3413, and the second sliding portion 342 may further include a second slider 3423. The first slider 3413 is fixed to the first cantilever 3411 and spaced apart from the first stop block 3412. The second slider 3423 is fixed to the second cantilever 3421 and spaced apart from the second stop block 3422. The first slider 3413 and the second slider 3423 are spaced apart from each other. Exemplarily, the first slider 3413 and the second slider 3423 may be positioned opposite each other. The first slider 3413 is slidably connected to the first side wall 11. The first slider 3413 engages with the first stop slot 112 of the first side wall 11. Exemplarily, in the first direction X, the first slider 3413 is smaller than the first stop slot 112 to facilitate sliding of the first slider 3413 within the first stop slot 112. The second slider 3423 is slidably connected to the second side wall 12. The second slider 3423 is inserted into the second limiting groove 122 of the second side wall 12. For example, in the first direction X, the size of the second slider 3423 is smaller than the size of the second limiting groove 122, so that the second slider 3423 can slide in the second limiting groove 122. Furthermore, the first limiting groove 112 and the second limiting groove 122 can respectively limit the upward movement of the first slider 3413 and the second slider 3423 in the first direction X.

[0100] In this embodiment, the first slider 3413 cooperates with the first limiting groove 112, and the second slider 3423 cooperates with the second limiting groove 122, allowing the dial key 3 to move upward in the first direction X relative to the base 1, thereby achieving sliding connection between the sliding portion 34 and the first side wall 11 and the second side wall 12, thereby achieving a sliding connection between the dial key 3 and the base 1. In addition, the first slide groove 111 restrains the first limiting block 3412 of the dial key 3, and the second slide groove 121 restrains the second limiting block 3422 of the dial key 3, ensuring smooth and reliable sliding of the dial key 3 relative to the base 1.

[0101] In some embodiments, a first limiting space 35 can be formed between the first limiting block 3412 and the first sliding block 3413 in the second direction Y, and the first side wall 11 of the base 1 can be partially inserted into the first limiting space 35. The second limiting block 3422 and the second sliding block 3423 can form a second limiting space 36 in the second direction Y, and the second side wall 12 of the base 1 can be partially inserted into the second limiting space 36.

[0102] In this embodiment, by setting the first slider 3413 and the second slider 3423, the first limiting space 35 and the second limiting space 36 are formed respectively with the first limiting block 3412 and the first limiting block 3412, and the base 1 is partially inserted into the first limiting space 35 and the second limiting space 36, further limiting the movement of the dial key 3 relative to the base 1 in the second direction Y upward and the third direction Z upward, so that the installation of the base 1 and the dial key 3 is more stable.

[0103] In this embodiment, the structure of the dial key 3's body 31, first cantilever 3411, first stopper 3412, second cantilever 3421, and second stopper 3422 cooperates with the base 1, similarly enabling the dial key 3 to slide relative to the base 1. In other embodiments, the dial key 3 may not be provided with the first slider 3413 and the second slider 3423. The first slider 3413 may be formed by part or all of the body 31, first cantilever 3411, and first stopper 3412. The second slider 3423 may be formed by part or all of the body 31, second cantilever 3421, and second stopper 3422.

[0104] In some embodiments, the dial key 3 may further include a blocking portion 37, which is fixed to the body 31 and located on the same side of the body 31 as the sliding portion 34. The blocking portion 37 is disposed facing the third side wall 13. The blocking portion 37 may include a blocking plate 371 and a fixing post 372. The blocking plate 371 is fixed to the body 31 and spaced apart from the first cantilever 3411 and the second cantilever 3421. The fixing post 372 is fixed to the blocking plate 371 and disposed facing the third side wall 13. The blocking portion 37 of the dial key 3 cooperates with the third side wall 13 to mount and limit the first elastic member 4. The body 31 of the dial key 3 is provided with at least one blocking groove 312, which is located between the side wall of the dial key 3 and the blocking plate 371. The blocking groove 312 is used to mount the light guide 7.

[0105] Please refer to Figure 5A 、 Figure 5B 、 Figure 9B and Figure 13 , Figure 13 yes Figure 10 The structure shown is a schematic diagram of the structure at another angle along the cross section of DD. It should be noted that, Figure 13 To clearly show Figure 10 The structure shown is a schematic diagram of the cross section of the structure cut along DD. Figure 10 The components in the image are rotated by a certain angle.

[0106] In some embodiments, the lock tongue portion 32 of the dial key 3 can be snapped into the escape space 211 of the handle 2. The sliding surface 322 of the lock tongue portion 32 can be a beveled pin-shaped end surface to facilitate the lock tongue portion 32 being snapped into the escape space 211 of the handle 2. The installation space 311 between the abutting surface 321 and the body 31 can be used to accommodate the first connecting portion 221 of the lock catch portion 22. When the lock catch portion 22 is snapped into the installation space 311, the abutting surface 321 of the lock tongue portion 32 abuts the first connecting portion 221, thereby abutting the lock tongue portion 32 against the lock catch portion 22, thereby achieving abutment between the dial key 3 and the handle 2.

[0107] In some embodiments, the first elastic member 4 is located between the dial key 3 and the third side wall 13. Specifically, the first elastic member 4 can be located between the blocking portion 37 of the dial key 3 and the third side wall 13 of the base 1. The blocking portion 37 and the third side wall 13 act as a limiter for the first elastic member 4, allowing the first elastic member 4 to elastically abut the blocking portion 37 of the dial key 3 and the third side wall 13 of the base 1, thereby generating a first elastic force on the dial key 3. Exemplarily, the first elastic member 4 can be a spring, which is sleeved around the outer periphery of the fixing post 372. One end of the first elastic member 4 elastically abuts the blocking plate 371, while the other end of the first elastic member 4 elastically abuts and is located in the positioning groove 131 of the third side wall 13. In this embodiment, the fixing post 372 and the positioning groove 131 position the first elastic member 4, preventing the first elastic member 4 from tilting during compression and rebound, thereby stabilizing the position of the first elastic member 4. In some other embodiments, the first elastic member 4 may also be located at other positions between the dial key 3 and the third side wall 13. For example, the fixing column 372 may also be provided on the side of the first sliding portion 341 or the second sliding portion 342 facing the third side wall 13, so that the first elastic member 4 may be located between the first sliding portion 341 and the third side wall 13, or between the second sliding portion 342 and the third side wall 13, which is not strictly limited in this application.

[0108] In some embodiments, the second elastic member 5 is positioned between the abutting portion 25 of the handle 2 and the connecting portion 14 of the base 1. For example, the second elastic member 5 can be a spring, which is sleeved around the outer periphery of the positioning post 251 and the upright post 141. The ends of the second elastic member 5 elastically abut the abutting portion 25 and the connecting portion 14, respectively. In this embodiment, the positioning post 251 and the upright post 141 position the second elastic member 5, preventing it from tilting during compression and rebound, thereby stabilizing the position of the second elastic member 5.

[0109] In some embodiments, the hard drive bracket 10 can be applied to a removable hard drive assembly 100. The hard drive bracket 10 has a locked state and an unlocked state. When the hard drive bracket 10 is in the locked state, the dial button 3 abuts the handle 2, the locking tongue portion 32 of the dial button 3 abuts the locking portion 22 of the handle 2, the rotating portion 23 cannot rotate relative to the base 1, and the locking portion 24 of the handle 2 is used to snap into the chassis 200 to fix the hard drive assembly 100 to the chassis 200. The locking tongue portion 32 of the dial button 3 is located in the avoidance space 211 of the handle 2, the first connecting portion 221 of the locking portion 22 is located in the installation space 311 of the dial button 3, and the abutting surface 321 of the locking tongue portion 32 abuts the first connecting portion 221 of the locking portion 22. The locking tongue portion 32 of the dial button 3 generates a blocking force directed toward the locking portion 22 of the handle 2, thereby limiting the locking portion 22 from moving away from the base 1. At this time, the second elastic member 5 is in a compressed state and can generate a second elastic force on the handle 2 .

[0110] The dial button 3 is slid toward the side away from the handle 2, and the sliding portion 34 of the dial button 3 slides relative to the base 1, driving the lock tongue portion 32 to move toward the side away from the lock portion 22, and the hard disk bracket 10 can be switched from the locked state to the unlocked state. When the hard disk bracket 10 is in the unlocked state, the dial button 3 is disengaged from the handle 2, and the lock tongue portion 32 of the dial button 3 is disengaged from the lock portion 22 of the handle 2, and the rotating portion 23 can rotate relative to the base 1. The second elastic force of the second elastic member 5 pushes the first end of the handle 2 to rotate around the rotating portion 23 toward the side away from the base 1 (see Figure 8 ) to move the locking portion 22 of the handle 2 away from the base 1, thereby driving the engaging portion 24 of the handle 2 toward the side closer to the base 1. The engaging portion 24 disengages from the chassis 200, allowing the hard disk assembly 100 to be separated from the chassis 200. Under the action of the second elastic member, the handle 2 can automatically rotate the first end of the handle 2 about the rotating portion 23 toward the side away from the base 1 without applying external force, making the unlocking operation of the hard disk bracket 10 simpler. The dial button 3, handle 2, and base 1 constitute the limit assembly of the hard disk bracket 10, which is used to control the locking and unlocking between the hard disk assembly 100 and the chassis 200.

[0111] In this embodiment, the sliding portion 34 of the dial button 3 cooperates with the base 1 to enable the dial button 3 to move closer to or farther from the handle 2. The locking portion 22 of the handle 2 cooperates with the locking tongue portion 32 of the dial button 3 to control the dial button 3 to abut or disengage from the handle 2. Furthermore, the rotating portion 23 of the handle 2 can rotate relative to the base 1, driving the engaging portion 24 closer to or farther from the base, thereby locking and unlocking the hard disk bracket 10.

[0112] Compared with the complex structure of the hard disk bracket limit assembly in the prior art, in this embodiment, the handle 2 can be quickly unlocked by only sliding the dial key 3. The hard disk bracket 10 has fewer components for controlling the locking and unlocking of the hard disk assembly 100, the structure of the limit assembly is simpler, and the components are easy to assemble, so the production cost of the hard disk bracket 10 is lower.

[0113] In some embodiments, the first elastic member 4 is located between the blocking portion 37 of the dial key 3 and the third side wall 13 of the base 1. The first elastic member 4 is in a compressed state to generate a first elastic force, which is used to drive the dial key 3 toward the handle 2. In this embodiment, under the push of the first elastic force of the first elastic member 4, when the hard disk bracket 10 is in the locked state, the abutment between the locking tongue portion 32 of the dial key 3 and the locking portion 22 of the handle 2 is more stable, and the dial key 3 is not easily separated from the handle 2. In addition, because the first elastic force of the first elastic member 4 stabilizes the abutment between the dial key 3 and the handle 2, the sliding resistance of the dial key 3 when sliding in the base 1 can be designed to be relatively small. The user can dial the dial key 3 with less force, which helps to improve the user experience.

[0114] In other embodiments, when the hard disk bracket 10 is in the locked state, the first elastic member 4 may not be in the compressed state. The sliding resistance of the dial key 3 when sliding in the base 1 may also be designed to be relatively large. Relying on the sliding resistance between the dial key 3 and the base 1 can also achieve stable contact between the dial key 3 and the handle 2. This application does not impose strict restrictions on this.

[0115] In some embodiments, when the hard disk bracket 10 is in the unlocked state, the first elastic member 4 is in a compressed state, generating a first elastic force on the dial button 3 toward the handle 2. The first elastic force is used to drive the dial button 3 to move toward the side close to the handle 2. At the same time, the first limiting groove 112 and the second limiting groove 122 respectively limit the first slider 3413 and the second slider 3423 in the first direction X upward (see Figure 12 The first and second slots 111 and 121 respectively limit the first and second limit blocks 3412 and 3422 in the first direction X. The first elastic force, the sliding portion 34 of the dial button 3, and the base 1 allow the dial button 3 to return to its initial position when the hard drive bracket 10 is in the locked state.

[0116] In this embodiment, the dial button 3 automatically rebounds under the action of the first elastic member 4 without applying any external force, simplifying the locking operation of the hard disk bracket 10. Furthermore, the sliding portion 34 of the dial button 3 cooperates with the base 1 to return the dial button 3 to its initial position, preventing the dial button 3 from exceeding its initial position under the action of the first elastic member 4, thereby improving the user experience of the hard disk bracket 10.

[0117] In some embodiments, when the hard disk bracket 10 is in the unlocked state, the operator can push the first end of the handle 2 to rotate around the rotating portion 23 toward the side close to the base 1, so that the locking portion 22 of the handle 2 is close to the base 1, and the locking portion 22 is snapped into the installation space 311 of the dial key 3, so that the locking portion 22 is against the locking portion 22, thereby achieving the abutment between the dial key 3 and the handle 2, and the hard disk bracket 10 is changed from the unlocked state to the locked state.

[0118] In some embodiments, when the hard drive bracket 10 is in the locked state, the side wall of the dial button 3 is retracted relative to the third side wall 13 of the base 1 in the first direction X. When the hard drive bracket 10 is in the unlocked state, the side wall of the dial button 3 can be retracted relative to or flush with the third side wall 13 of the base 1 in the first direction X. That is, in the first direction X, a certain distance is left between the side wall of the dial button 3 and the third side wall 13 of the base 1 to prevent the dial button 3 from abutting against the chassis 200 when the hard drive bracket 10 is unlocked, thereby ensuring the reliability of the hard drive bracket 10.

[0119] Please refer to Figure 4 、 Figure 14A 、 Figure 14B and Figure 15 , Figure 14A yes Figure 4 The structure diagram of the bracket 6 in some embodiments is shown. Figure 14B yes Figure 14A The structural diagram of the bracket 6 shown in another angle is as follows: Figure 15 yes Figure 14B The cross-sectional structure diagram of the bracket 6 is shown along line EE.

[0120] In some embodiments, the bracket 6 is fixed to the side of the base 1 facing away from the handle 2, and the shielding spring 8 is located between the base 1 and the bracket 6. The hard drive bracket 10 may also include multiple second fixing members 101. Exemplarily, the second fixing members 101 may be screws, which are used to secure the bracket 6, the shielding spring 8, and the base 1 together. The shielding spring 8 is used to prevent electromagnetic interference and is provided with multiple through holes to facilitate heat dissipation from the hard drive 20.

[0121] In some embodiments, the bracket 6 may include a first side panel 61, a second side panel 62, and a third side panel 63. The first side panel 61 and the second side panel 62 are disposed opposite each other, and the third side panel 63 is connected between the first side panel 61 and the second side panel 62. The third side panel 63 is fixedly connected to the base 1. The first side panel 61 includes a snap-fitting member 64, which is fixedly connected to the first side panel 61 and located on the inner side of the bracket 6. The snap-fitting member 64 includes a connecting plate 641 and a snap-fitting member 642. The connecting plate 641 is connected to the first side panel 61 and bends relative to the first side panel 61 in a direction opposite to the first direction X of the first side panel 61. The snap-fitting member 642 is connected to the connecting plate 641 and bends relative to the connecting plate 641 in a second direction Y of the connecting plate 641. The first side panel 61 also includes a clearance hole 643, which is disposed opposite the snap-fitting member 642. The first side panel 61 is further provided with at least one engaging groove 65, which is spaced apart from the engaging member 64. For example, the engaging groove 65 can be a rectangular opening or a rectangular slot, and the engaging groove 65 and the engaging member 64 can be located in the middle of the first side panel 61. The engaging member 64 and the engaging groove 65 are used to mount the light guide 7.

[0122] In some embodiments, the first side panel 61 is provided with at least one first elastic piece 66a, which protrudes outward from the bracket 6 relative to the first side panel 61. On the first side panel 61, the first elastic piece 66a may include a first connecting segment 661 and a second connecting segment 662 connected in sequence. The first connecting segment 661 is fixedly connected to the first side panel 61, and the first connecting segment 661 and the second connecting segment 662 protrude away from the first side panel 61. Exemplarily, the first elastic piece 66a may be formed by bending the first side panel 61. It is understood that the second elastic piece 66b on the second side panel 62 may be configured similarly to the first elastic piece 66a on the first side panel 61.

[0123] In this embodiment, when the hard disk assembly 100 is installed in the server chassis 200, the first spring clip 66a is compressed between the chassis 200 and the first side panel 61, and the second spring clip 66b is compressed between the chassis 200 and the second side panel 62. The first spring clip 66a and the second spring clip 66b are located in the gap between the chassis 200 and the bracket 6, providing support and shock absorption for the bracket 6. This helps improve the seismic resistance parameters of the hard disk assembly 100 at different vibration frequencies, resulting in stronger seismic resistance of the hard disk assembly 100 and higher operational reliability of the hard disk 20. In addition, the provision of the first spring clip 66a, the second spring clip 66b, and / or the engaging member 64 helps enhance the structural strength of the first side panel 61 and the second side panel 62.

[0124] At least one first spring piece 66a is provided with a protrusion 663, which protrudes outward from the bracket 6 relative to the first spring piece 66a. The protrusion 663 on the outside of the first spring piece 66a can reduce scraping between the hard disk assembly 100 and the chassis 200 during installation and removal, thereby avoiding the generation of metal debris and preventing it from adversely affecting other components. It is understood that the protrusion 663 on the second spring piece 66b (not shown) can also be configured similarly to the protrusion 663 on the first spring piece 66a; alternatively, the second spring piece 66b may not be provided with the protrusion 663, and this is not strictly limited in this application.

[0125] In addition, one of the first side panel 61 or the second side panel 62 is provided with an escape notch 67, and the escape notch 67 is located at the end of the bracket 6 facing away from the base 1. Exemplarily, the end of the first side panel 61 facing away from the third side panel 63 is provided with an escape notch 67, and the escape notch 67 can be located on the first elastic piece 66a of the first side panel 61. In addition, a stop post (not shown in the figure) is provided at the corresponding position of the chassis 200. When the hard disk assembly 100 is inserted into the chassis 200 in the correct direction, the stop post can smoothly pass through the escape notch 67 of the first side panel 61, abut against the first elastic piece 66a, forming a flexible stop, and the hard disk assembly 100 can be successfully installed in the chassis 200. When the hard disk assembly 100 is inserted into the chassis 200 in the wrong direction, the end of the second side panel 62 blocks the stop post, and the hard disk assembly 100 cannot be installed in the chassis 200. In this embodiment, the arrangement of the avoidance notch 67 on the bracket 6 can prevent the hard disk assembly 100 from being installed incorrectly, thereby reducing the risk of damage to the hard disk assembly 100 during insertion.

[0126] Please refer to Figure 3 、 Figure 14A and 14B In some embodiments, the bracket 6 may further include a base plate 68, which is positioned between the first side plate 61 and the second side plate 62. The base plate 68 may include a first base plate 681 and a second base plate 682, spaced apart from each other. The first base plate 681 is connected to the first side plate 61 and is substantially perpendicular to the first side plate 61. The second base plate 682 is connected to the second side plate 62 and is substantially perpendicular to the second side plate 62. The first base plate 681 has a plurality of first recesses 683, each of which protrudes from the base plate 68 toward a side away from the first side plate 61. The first base plate 681 has a mounting hole 684, spaced apart from the first recesses 683. The mounting hole 684 is used to mount the first fixing member 30. It is understood that the second recesses 685 and mounting hole 684 on the second base plate 682 can be configured similarly to the first recesses 683 and mounting hole 684 on the first base plate 681. The hard disk 20 is installed inside the bracket 6 and fixed to the bottom plate 68 of the bracket 6 via a first fixing member 30 .

[0127] In this embodiment, the bottom plate 68 of the bracket 6 is provided with a first recessed groove 683 and a second recessed groove 685, which enhance the structural strength of the bottom plate 68. Furthermore, the first recessed groove 683 protrudes from the side of the first bottom plate 681 facing away from the first side plate 61, and the second recessed groove 685 protrudes from the side of the second bottom plate 682 facing away from the second side plate 62. The first recessed groove 683 and the second recessed groove 685 prevent the protruding portion of the first fixing member 30 from scraping against other components when the first fixing member 30 is installed on the bottom plate 68, thereby preventing the generation of metal debris.

[0128] In some embodiments, the insulating sheet 9 is positioned against the bottom plate 68 of the bracket 6. Exemplarily, the insulating sheet 9 may include a first insulating sheet 91 and a second insulating sheet 92, which are respectively attached to the first bottom plate 681 and the second bottom plate 682. The insulating sheet 9 is positioned between the hard drive 20 and the bottom plate 68 of the bracket 6 to prevent the exposed circuit board of the hard drive 20 from contacting the bracket 6 and causing a short circuit.

[0129] In some embodiments, the bracket 6 is an integrally formed sheet metal part, and the thickness of the sheet metal part is in the range of 0.2 mm to 1.5 mm. The thickness of the sheet metal part can be 0.2 mm, 0.3 mm, 0.5 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.15 mm, 1.2 mm, 1.5 mm, etc. The material of the bracket 6 can be stainless steel, such as 304 stainless steel, 302 stainless steel, etc., which is not strictly limited in this application. The bracket 6 can be made by mold processing or digital punching. For example, the thickness of the sheet metal part is 0.3 mm. The dimension of the hard disk 20 in the first direction X-up is 70.7 mm, and the dimension of the entire hard disk assembly 100 in the first direction X-up is only 71.6 mm.

[0130] Compared to the plastic bracket 6 in the prior art, in this embodiment, the bracket 6 is an integrally formed sheet metal part. When the thickness of the sheet metal part is 0.3 mm, the size of the bracket 6 in the first direction X is the smallest, so that the space occupied by the entire hard disk assembly 100 is minimized. Under the premise of standardized dimensions of the server chassis 200, more hard disk assemblies 100 in this embodiment can be configured in the chassis 200, which helps to improve the computing speed and storage capacity of the server. The bracket 6 is made of stainless steel and has high strength. In addition, the first spring piece 66a and the engaging member 64 arranged on the first side wall 11, the second spring piece 66b arranged on the second side wall 12, and the first sink groove 683 and the second sink groove 685 arranged on the bottom plate 68 can ensure that the bracket 6 still has good structural strength even when the thickness is relatively small.

[0131] Please refer to Figure 4 、 Figure 15 and Figure 16 , Figure 16 yes Figure 3 The cross-sectional structure diagram of the hard disk bracket 10 is shown along FF.

[0132] In some embodiments, a light guide 7 is fixed to the bracket 6 and extends from the side of the bracket 6 facing away from the base 1 to the dial key 3. The light guide 7 can be used to transmit light from a light source located on the side of the bracket 6 facing away from the base 1 to the dial key 3. The dial key 3 can be made of plastic, for example, polycarbonate, with a coating on the plastic surface to make the dial key 3 translucent. Light from the light guide 7 can be emitted from the dial key 3 to indicate the installation status of the hard disk assembly 100.

[0133] In some embodiments, the light guide 7 may include a first light guide bar 71, a second light guide bar 72, and a first clip 73. The first light guide bar 71 and the second light guide bar 72 are spaced apart, and the first clip 73 is fixed between the first light guide bar 71 and the second light guide bar 72. The first clip 73 clips into the first side panel 61. Exemplarily, the first clip 73 may be a plate-shaped structure. In addition, the first light guide bar 71 and / or the second light guide bar 72 are provided with at least one second clip 74. Exemplarily, the first light guide bar 71 is provided with at least one second clip 74; alternatively, the second light guide bar 72 is provided with at least one second clip 74; or both the first light guide bar 71 and the second light guide bar 72 are provided with at least one second clip 74. The second clip 74 faces the first side panel 61 and is spaced apart from the first clip 73. The second clip 74 clips into the first side panel 61. The limiting direction of the second clamping portion 74 by the first side plate 61 is different from the limiting direction of the first clamping portion 73 .

[0134] Among them, the first clamping portion 73 is clamped to the clamping member 64 of the first side plate 61, and the first clamping portion 73 can be located in the avoidance hole 643 of the first side plate 61. The first clamping portion 73 abuts the connecting plate 641. The connecting plate 641 and the clamping plate 642 of the clamping member 64 respectively limit the first clamping portion 73 in the second direction Y upward and the first direction X upward. The second clamping portion 74 is clamped to the clamping groove 65 of the first side plate 61, and the clamping groove 65 limits the second clamping portion 74 in the second direction Y upward. In the second direction Y upward, the limiting direction of the first clamping portion 73 by the clamping member 64 is opposite to the limiting direction of the second clamping portion 74 by the clamping groove 65. Exemplarily, the engaging member 64 is close to the third side plate 63 relative to the engaging slot 65, and the limiting direction of the engaging member 64 with respect to the first engaging portion 73 is toward the third side plate 63, and the limiting direction of the engaging slot 65 with respect to the second engaging portion 74 is away from the third side plate 63; or, the engaging slot 65 is close to the third side plate 63 relative to the engaging member 64, and the limiting direction of the engaging member 64 with respect to the first engaging portion 73 is away from the third side plate 63, and the limiting direction of the engaging slot 65 with respect to the second engaging portion 74 is toward the third side plate 63.

[0135] In this embodiment, the light guide 7 can be installed on the first side plate 61 of the bracket 6 by the first clamping portion 73 and the second clamping portion 74. The clamping member 64 of the first side plate 61 limits the light guide 7 in the second direction Y upward and the first direction X upward, and the clamping member 64 and the clamping groove 65 limit the light guide 7 in opposite directions. A clamping connection is formed between the light guide 7 and the first side plate 61, so that the fixation of the light guide 7 to the bracket 6 is more stable, and the light guide 7 can be prevented from being displaced relative to the bracket 6 due to external force.

[0136] In some embodiments, the second engaging portion 74 is provided with an oblique pin-shaped end surface on a side facing away from the first engaging portion 73 to facilitate smooth engagement of the second engaging portion 74 with the engaging groove 65. In other embodiments, the bracket 6 may not be provided with the engaging groove 65, and the light guide 7 may be fixed only by the engaging member 64. This application is not strictly limited to this.

[0137] Please refer to Figure 4 、 Figure 9B 、 Figure 16 and Figure 17 , Figure 17 yes Figure 16 A magnified schematic diagram of the structure at B in the middle.

[0138] In some embodiments, the material of the light guide 7 can be a plastic light guide material such as polycarbonate, polymethyl methacrylate, epoxy resin, etc. The light guide 7 can be formed by open mold processing. The end of the light guide 7 facing away from the bracket 6 is embedded in the blocking groove 312 of the dial key 3. Exemplarily, the ends of the first light guide bar 71 and the second light guide bar 72 facing away from the bracket 6 can both be embedded in the blocking groove 312 of the dial key 3. When the dial key 3 is against the handle 2, the light guide 7 is away from the blocking plate 371 of the dial key 3. When the dial key 3 is separated from the handle 2, the light guide 7 can be against the blocking plate 371 of the dial key 3, and the light guide 7 is deformed to generate a third elastic force, which is used to drive the dial key 3 closer to the handle 2. In the first direction X upward, the size of the blocking groove 312 is larger than the size of the light guide 7.

[0139] In this embodiment, one end of the light guide 7 is embedded in the blocking groove 312 of the dial key 3, thereby limiting the upward movement of the dial key 3 in the first direction X. Furthermore, the plastic light guide 7 has a certain elasticity. When the blocking plate 371 of the dial key 3 abuts the light guide 7, the light guide 7 exerts a third elastic force on the blocking plate 371, which pushes the dial key 3 toward the handle 2. Without applying any external force, the dial key 3 automatically rebounds, returning to its initial position when the hard drive bracket 10 is locked.

[0140] In some other embodiments, the light guide 7 may not be embedded in the inner side of the dial key 3 , and the dial key 3 may also automatically rebound by relying solely on the first elastic member 4 . This application does not impose a strict limitation on this.

[0141] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
