For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0051] When there are many other components around the hard disk box or hard disk rack in the case, especially when there are high components, in order to avoid the process of disassembling the hard disk by hand or auxiliary tools from causing damage to other components, it is necessary to be very careful during operation, which undoubtedly increases the difficulty of disassembling the hard disk and makes the operation not convenient enough, thereby affecting the efficiency of disassembling the hard disk.

[0052] In view of the above problems, the present application considers improving the hard disk mounting rack from the aspect of automatic lifting. When the hard disk needs to be disassembled, the hard disk mounting rack can be automatically lifted to a state higher than the surrounding other components, that is, the hard disk mounting rack has sufficient operating space around it, so that the hard disk can be conveniently disassembled on the hard disk mounting rack. At the same time, considering the problem of fixing the hard disk, a limiting part is also designed. After the hard disk is installed and the hard disk mounting rack is pressed and lowered, the hard disk mounting rack is locked and cannot be lifted by the limiting part, so as to ensure the structural stability and working reliability of the hard disk during use.

[0053] According to one aspect of the embodiments of the present application, a hard disk mounting rack is provided, please refer to Figures 1 to 3 , wherein Figure 1 and Figure 2 respectively show the structure of the hard disk mounting rack in the lowered state and the raised state, Figure 3 shows the exploded structure of the hard disk mounting rack. As Figure 1As shown in the middle, the hard disk mounting rack 100 comprises a bracket 110, a lifting mechanism 120 and a bearing table 130. The bracket 110 is fixedly connected to the inner wall of the case of the case, which can be connected by screws, rivets, welding, clamping, etc. The bearing table 130 is used to install the hard disk. Specifically, the bearing table 130 can be provided with a fixed column 131, and the fixed column 131 is inserted into the fixed hole 210 of the hard disk 200 to limit the hard disk 200 in the horizontal direction. In addition, a pressing plate, a latch and the like can be provided to limit the hard disk 200 in the vertical direction, so that the hard disk 200 is stably and reliably installed and fixed on the bearing table 130. Figure 4 As shown in the middle, the hard disk mounting rack 100 comprises a bracket 110, a lifting mechanism 120 and a bearing table 130. The bracket 110 is fixedly connected to the inner wall of the case of the case, which can be connected by screws, rivets, welding, clamping, etc. The bearing table 130 is used to install the hard disk. Specifically, the bearing table 130 can be provided with a fixed column 131, and the fixed column 131 is inserted into the fixed hole 210 of the hard disk 200 to limit the hard disk 200 in the horizontal direction. In addition, a pressing plate, a latch and the like can be provided to limit the hard disk 200 in the vertical direction, so that the hard disk 200 is stably and reliably installed and fixed on the bearing table 130.

[0054] Please refer to Figure 3 , the lifting mechanism 120 comprises a fixed component 121, an elastic component 122 and a moving component 123, and the fixed component 121 is fixedly connected to the bracket 110. The moving component 123 is connected to the fixed component 121 in a lifting manner, and the elastic component 122 is connected between the fixed component 121 and the moving component 123, which is used to provide the moving component 123 with an elastic force that is lifted relative to the fixed component 121. In Figure 1 and Figure 2 the perspective view, the elastic force is upward, and the moving component 123 is fixedly connected to the bearing table 130.

[0055] The fixed component 121 can be a track, and the moving component 123 can be a sliding block or a sliding rail slidingly arranged in the track. The lifting and sliding of the sliding block or the sliding rail in the track drives the bearing table 130 to lift relative to the bracket 110, and the elastic component 122 can be a spring or a spring sheet.

[0056] In addition, for the specific implementation of the lifting mechanism 120, in Figure 3 the specific embodiment shown, the top end of the fixed component 121 can be provided with a mounting groove 1211, and the moving component 123 can be telescopically arranged in the mounting groove 1211. The elastic component 122 is arranged in the mounting groove 1211 and abuts against the fixed component 121 and the moving component 123 at both ends. Thus, the moving component 123 and the fixed component 121 share a certain space in the vertical direction, so as to reduce the overall height of the hard disk mounting rack 100.

[0057] In order to further reduce the space occupied by the hard disk mounting rack 100 in the vertical direction after installation, as shown in Figure 5 and Figure 6The sectional structure of the lifting mechanism 120 in the lowered state and the raised state is shown in the drawings. The fixed part 121 and the movable part 123 can both adopt a cylindrical structure. The opening of the fixed part 121 (i.e. the slot of the mounting slot 1211) faces upward, and the opening of the movable part 123 faces downward. The movable part 123 can be telescopically inserted into the mounting slot 1211 of the fixed part 121. In the lowered state as shown in Figure 5 , the elastic part 122 is located inside the movable part 123. In the raised state as shown in Figure 6 , the elastic part 122 is partially located inside the fixed part 121 and partially located inside the movable part 123. This arrangement can ensure that the lifting mechanism 120 has the smallest size in the vertical direction, thereby minimizing the space occupied in the vertical direction inside the case during installation, which is conducive to the miniaturization design of the product.

[0058] In order to adapt to the lifting mode in which the movable part 123 is telescopically arranged in the fixed part 121, the structure of the bracket 110 is further designed accordingly in the embodiments of the present application. Please refer to Figure 3 . The bracket 110 includes a support plate 112 arranged vertically, a first connecting plate 113 extending horizontally from the bottom edge of the support plate 112, and a second connecting plate 114 extending horizontally from the top edge of the support plate 112. The first connecting plate 113 and the second connecting plate 114 extend in the same direction, i.e. the first connecting plate 113 and the second connecting plate 114 extend horizontally from the bottom edge and the top edge of the support plate 112 in the same direction, respectively.

[0059] The first connecting plate 113 is used to be fixedly connected with the case. Specifically, a hole 1131 can be arranged on the first connecting plate 113. A threaded fastener can pass through the hole 1131 and be threadedly connected with the wall of the case, thereby achieving the fixation of the first connecting plate 113 on the case. Alternatively, the first connecting plate 113 can be fixedly connected with the case by a pull rivet. Of course, the first connecting plate 113 can also be fixed to the case by welding, clamping or other methods, which are not limited here.

[0060] Please continue to refer to Figure 3 , and further combine with Figure 5 and Figure 6The fixing component 121 is arranged between the first connecting plate 113 and the second connecting plate 114, the first connecting plate 113 is provided with a first through hole 1132, the bottom end of the fixing component 121 is provided with a first connecting hole 1212, and the first fastener 1241 is connected with the first connecting hole 1212 after penetrating through the first through hole 1232 from the bottom of the first connecting plate 113, so as to fix and connect the fixing component 121 to the first connecting plate 113. Specifically, the first fastener 1241 can be a screw, the first connecting hole 1212 is a threaded hole, the screw is connected and fixed with the threaded hole after penetrating through the first through hole 1232, or the first fastener 1241 can also be a rivet, the first connecting hole 1212 is a riveting hole, and the rivet is riveted and fixed with the riveting hole after penetrating through the first through hole 1232.

[0061] As shown in Figure 3 、 Figure 5 and Figure 6 , the bearing table 130 is arranged on the side of the second connecting plate 114 away from the first connecting plate 113, the second connecting plate 114 is provided with a relief hole 1141, and the top end of the fixing component 121 is limitingly connected in the relief hole 1141, so that the bottom and top of the fixing component 121 are fixed by the first connecting plate 113 and the second connecting plate 114 respectively, to ensure the stability of the installation of the fixing component 121. The moving component 123 penetrates through the relief hole 1141 and abuts against the bottom of the bearing table 130. The bearing table 130 is provided with a second through hole 133, the top end of the moving component 123 is provided with a second connecting hole 1231, and the second fastener 1242 is connected with the second connecting hole 1231 after penetrating through the second through hole 133 from the top of the bearing table 130, so as to fix and connect the bearing table 130 and the moving component 123. The second fastener 1242 and the second connecting hole 1231 can also be connected in a threaded fastener and threaded hole cooperation mode, a rivet and a riveting hole cooperation mode, and the like, which will not be described herein.

[0062] After the hard disk 200 is installed, it is necessary to ensure that the bearing table 130 remains in a lowered state, therefore, please refer to Figures 1 to 3 , the bracket 110 is provided with a first limiting portion 111, and the bearing table 130 is provided with a second limiting portion 132, the second limiting portion 132 is used to be connected with the first limiting portion 111 when the bearing table 130 is lowered by the moving component 123, so as to limit the bearing table 130 from being raised. The second limiting portion 132 is also used to make the bearing table 130 be raised by the moving component 123 when the first limiting portion 111 is disengaged.

[0063] The first limiting part 111 can be an abutting surface, and the second limiting part 132 can be a locking mechanism. When it is required to keep the bearing table 130 in the lowered state, the locking mechanism can be moved to abut against the abutting surface to limit the bearing table 130. When it is required to raise the bearing table 130, the locking mechanism can be moved to separate from the abutting surface to release the raising limitation of the bearing table 130. In addition, the first limiting part 111 can be a socket, and the second limiting part 132 can be a plug. The plug can be inserted into or separated from the socket to lock or unlock the lifting movement of the bearing table 130.

[0064] On the basis of the structure of the support 110 provided in the above embodiment, the first limiting part 111 and the second limiting part 132 are further designed in the application. For details, please refer to Figure 2 and Figure 3 The first limiting part 111 includes a limiting hole 1111 formed in the second connecting plate 114, and the limiting hole 1111 is non-circular. The second limiting part 132 includes a limiting knob 1321 penetrating through the bearing table 130 and rotationally connected with the bearing table 130. The limiting knob 1321 is oppositely arranged with the limiting hole 1111 in the vertical direction. The bottom end of the limiting knob 1321 has a clamping end 1322, and the top end is provided with a screwing part 1323. The clamping end 1322 is non-circular in cross section, and the screwing part 1323 is used to drive the clamping end 1322 to rotate between the first angle and the second angle.

[0065] Specifically, as shown in Figure 3 , the limiting hole 1111 can be circular in the middle region and has two small notches at the edges. The clamping end 1322 is correspondingly circular in the middle region and has two small protrusions at the edges. When the bearing table 130 is in the lowered position and the clamping end 1322 is rotated to the first angle, as shown in the side view in Figure 7 , the plane where the second connecting plate 114 is located is taken as a projection plane A. The projection T1 of the clamping end 1322 in the vertical direction partially exceeds the region T2 of the limiting hole 1111 in the projection plane A. The entity structure corresponding to the projection of the exceeding part on the clamping end 1322 is an abutting structure 13221. At this time, the abutting structure 13221 abuts against the bottom of the second connecting plate 114 to limit the raising of the bearing table 130. Figure 7 On the basis of this, the clamping end 1322 is rotated to the second angle to the state shown in Figure 8 . The plane where the second connecting plate 114 is located is taken as the projection plane A. At this time, the projection T1 of the clamping end 1322 in the vertical direction is entirely within the region T2 of the limiting hole 1111. Therefore, the clamping end 1322 can pass through the limiting hole 1111, so that the bearing table 130 can be raised under the driving of the moving part 123, and finally raised to the position shown in Figure 9 .

[0066] In addition to the shape provided in the above embodiment, where the middle area is circular and the edge has two small notches or protrusions, the limiting hole 1111 and the snap-fit ​​end 1322 can also be elliptical, rectangular, square, polygonal, irregular curved surface, etc., as long as it is ensured that the snap-fit ​​end 1322 can abut against the bottom of the second connecting plate 114 when rotated to the first angle, and can pass through the limiting hole 1111 when rotated to the second angle.

[0067] Regarding the specific installation method of the limit knob 1321, this application proposes an implementation scheme, please refer to it again for details. Figure 3 and further combine Figure 10 , Figure 10 The diagram shows a cross-sectional structure at the limiting knob 1321. The support platform 130 has a mounting post 115 protruding from its top around the limiting hole 1111. The mounting post 115 has a mounting hole 1151 that extends vertically and communicates with the limiting hole 1111. The top of the mounting hole 1151 has a narrowed opening 1152. The top of the limiting knob 1321 has a connecting end 13211 with a reduced cross-sectional area. The limiting knob 1321 passes sequentially from its bottom end into the limiting hole 1111 and the mounting hole 1151. The connecting end 13211 protrudes from the opening 1152 and connects to the screwing part 1323. Specifically, the connecting end 13211 can be a stud, and the screwing part 1323 can have a threaded hole for connection with the stud. Alternatively, the connecting end 13211 and the screwing part 1323 can be connected by riveting, snap-fitting, or other methods; specific details are not limited here. The inner and outer surfaces of the mounting post 115 around the orifice 1152 abut against the limiting knob 1321 and the screwing part 1323 respectively, so as to limit the second limiting part 132 in the vertical direction, so that the second limiting part 132 is always connected to the support platform 130.

[0068] Considering that the screwing part 1323 needs to drive the limit knob 1321 to rotate, based on this, regarding the connection method between the connecting end 13211 and the screwing part 1323 stud, in order to prevent relative rotation at the threaded connection when rotating the screwing part 1323, which would prevent the limit knob 1321 from rotating normally, as follows: Figure 10 As shown, an elastic element 134 is sleeved on the connecting end 13211. The elastic element 134 abuts between the limiting knob 1321 and the screwing part 1323. The elastic element 134 is used to provide an outward elastic force to both sides so that the threaded connection between the screwing part 1323 and the connecting end 13211 fits tightly. This allows the screwing part 1323 to effectively drive the limiting knob 1321 to rotate when it is under force, thereby realizing reliable adjustment of the lifting, locking and unlocking of the support platform 130.

[0069] like Figure 3As shown in the figures, in order to improve the stability of the overall hard disk mounting rack 100 on the chassis, in some embodiments, the support 110 can be provided in multiple numbers and arranged at the bottom of at least part of the edges of the bearing table 130. In addition, in order to improve the reliability of the lifting of the bearing table 130, a plurality of lifting mechanisms 120 can be arranged on each support 110. In addition, in order to improve the stability of the locking of the bearing table 130, each support 110 can be limited by at least one second limiting portion 132 and the first limiting portion 111 on the bearing table 130.

[0070] Referring to Figure 11 , the bearing table 130 can also be detachably connected to the hard disk box 140, and the hard disk box 140 is used to mount the hard disk 200. Specifically, the hard disk box 140 can be detachably connected to the bearing table 130 by screws, clamping, etc.

[0071] In summary, in the hard disk mounting rack 100 provided by the embodiments of the present application, the support 110 is responsible for connecting with the chassis, the bearing table 130 is responsible for mounting the hard disk 200, the bearing table 130 is connected to the support 110 by the lifting mechanism 120 and is locked and unlocked by the limiting cooperation of the second limiting portion 132 and the first limiting portion 111. When the hard disk needs to be disassembled, the lifting restriction of the bearing table 130 is released, and the bearing table 130 will be automatically lifted under the driving of the lifting mechanism 120, so that the hard disk mounting rack 100 is higher than other parts in the chassis around it, that is, there is more operating space around the hard disk mounting rack 100, so as to facilitate the disassembly and assembly of the hard disk 200. After the disassembly and assembly of the hard disk 200 are completed, the bearing table 130 is pressed downward to lower it, and then the second limiting portion 132 and the first limiting portion 111 are adjusted to the limiting connection state, and the bearing table 130 is locked at the lowered position, so that the hard disk 200 does not lift during operation, ensuring the stability and reliability of the hard disk 200 during operation.

[0072] The existing chassis generally needs to remove the wall panel of the box body to disassemble and assemble the hard disk in the box body, which makes the disassembly and assembly process of the hard disk complex and tedious. In view of this problem, according to another aspect of the embodiments of the present application, a chassis is also provided, please refer to Figure 12 and Figure 13 The chassis 400 includes a box body 300 and the hard disk mounting rack 100 provided by any of the above embodiments, and the hard disk mounting rack 100 is arranged on the inner wall of the box body 300.

[0073] In order to be able to disassemble and assemble the hard disk 200 more conveniently, such as Figure 12 and Figure 13As shown, a dismounting opening 310 is formed on the box 300 at a position opposite to the hard disk mounting rack 100, and the bearing table 130 moves towards the dismounting opening 310 when it is raised. An openable cover plate 320 is arranged at the dismounting opening 310.

[0074] In this embodiment, based on the structure design that the hard disk mounting rack 100 is liftable, a dismounting opening 310 is formed on the box 300 at a position opposite to the hard disk mounting rack 100. When it is necessary to dismount the hard disk 200, the dismounting opening 310 is only needed to be opened and the hard disk mounting rack 100 is automatically raised to the dismounting opening 310 or extended from the dismounting opening 310, so that the hard disk 200 can be dismounted without the need to dismount the whole wall plate of the box 300, which can simplify the dismounting steps of the hard disk 200 and improve the dismounting efficiency.

[0075] As to the opening mode of the cover plate 320, the present application provides a sliding scheme inside the box 300, which will be described in detail with reference to Figure 14 , which shows the inside structure of the wall plate of the box 300 where the dismounting opening 310 is located. As shown, the inner walls of the opposite two side edges of the dismounting opening 310 are provided with tracks 330, and the tracks 330 are provided with elastic abutting members 340. The two sides of the cover plate 320 are slidably arranged in the tracks 330, and the side of the cover plate 320 away from the dismounting opening 310 (i.e. the side of the cover plate 320 towards the inside of the box 300) abuts against the elastic abutting members 340. As shown in Figure 13 , the cover plate 320 is provided with a first clamping part, and the box 300 is provided with a second clamping part. When the cover plate 320 is in the state of closing the dismounting opening 310 as shown in Figure 12 , the first clamping part and the second clamping part are clamped to limit the sliding of the cover plate 320. When the cover plate 320 is pressed, it moves inwardly through the deformation of the elastic abutting members 340 to separate the second clamping part from the second clamping part, so that the cover plate 320 can slide along the tracks 330 and open the dismounting opening 310.

[0076] Specifically, the elastic abutting members 340 can be elastic sheets arranged in the tracks 330 and extending in a wave shape as shown in Figure 14 . The elastic abutting members 340 can be fixed to the inner side walls of the tracks 330 by fasteners 341, and the cover plate 320 is clamped between the elastic abutting members 340 and the outer side walls of the tracks 330 and is slidable. Of course, the elastic abutting members 340 can also be soft rubber pads or friction pads connected to the tracks 330 by springs. The essence of them is to use the elastic reset ability to make the cover plate 320 be clamped inside the tracks 330 when it is not subjected to external force, and to use the compression ability of the elastic members to make the cover plate 320 move inwardly a certain distance to remove the sliding limitation of the cover plate 320 between the clamping of the first clamping part and the second clamping part when the cover plate 320 is subjected to pressure.

[0077] The second clamping part can include Figure 14The protrusion 301 shown is located on the inner wall of the housing 300. The first snap-fit ​​part can be... Figure 13 The groove 321 shown is provided on the outer surface of the cover plate 320. When the cover plate 320 is closed, the protrusion 301 engages with the groove 321 to restrict the sliding of the cover plate 320. When it is necessary to open the cover plate 320, press the cover plate 320 inside the groove 321 to disengage the groove 321 from the protrusion 301, and then push the cover plate 320 to slide open the disassembly port 310. Further, as shown... Figure 12 As shown, a latch 323 can be provided on the outer side of the cover plate 320. The latch 323 can be a recessed structure as shown in the figure, or it can be a protruding structure. The latch 323 is used to allow the user to apply force with their fingers to push the cover plate 320 to slide.

[0078] In addition, such as Figure 13 The second snap-fit ​​portion may include the inner wall 302 of the housing 300 facing the disassembly port 310, that is, the wall of the space where the edge of the disassembly port 310 is located, such as... Figure 15 As shown, the first snap-fit ​​portion may include a stepped surface 322 formed by a protrusion on the outer surface of the cover plate 320, such as... Figure 12 When the disassembly opening 310 is closed, the stepped surface 322 is embedded in the disassembly opening 310, and the edge of the stepped surface 322 engages with the inner wall 302 of the disassembly opening 310, thus locking the cover plate 320 in the closed disassembly opening 310 state. Similarly, when it is necessary to open the disassembly opening 310, press the cover plate 320 inward so that the edge of the stepped surface 322 and the inner wall 302 of the disassembly opening 310 are misaligned along the sliding direction of the cover plate 320, and then push the cover plate 320 to slide open the disassembly opening 310.

[0079] Furthermore, when the cover plate 320 is limited by simultaneously using the method of the protrusion 301 engaging the groove 321, the edge of the step surface 322 can also be set as an arc surface or a slope surface. When the groove 321 separates from the protrusion 301 and pushes the cover plate 320, the cover plate 320 can slide smoothly inward by frictional cooperation between the arc surface or the slope surface and the inner wall 302 of the disassembly port 310. There is no need to apply additional force to separate the edge of the step surface 322 from the inner wall 302 of the disassembly port 310 before pushing the cover plate 320, which facilitates the opening operation of the cover plate 320.

[0080] Based on the step surface 322 on the cover plate 320, in order to ensure the reliability of the sliding of the cover plate 320, a limiting guide structure 350 is recessed inward on the box body 300. During the sliding opening of the cover plate 320, the limiting guide structure 350 and the edges on opposite sides of the step surface 322 are in frictional cooperation to limit and guide the sliding of the cover plate 320.

[0081] In summary, the embodiments of the present application adopt the cover plate 320 sliding on the inner wall of the box body 300 to open and close the dismounting opening 310, so as to ensure the flatness of the outer surface of the box body 300, ensure the neat appearance of the box body 300, and make the multiple chassis 400 more compact when stacked.

[0082] According to another aspect of the embodiments of the present application, a computer is also provided, please refer to Figure 12 The computer 500 comprises the chassis 400 in any of the above embodiments.
