[0044] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their descriptions will be omitted.

[0045] Combined with Figures 1 to 6 As shown, according to a specific embodiment of the present application, a data storage device is provided.

[0046] Specifically, as Figure 1 shown, the data storage device includes a box body 1 and a lifting plate 2. The box body 1 has a receiving cavity with an opening on one side. The lifting plate 2 is at least one, and the lifting plate 2 is located in the receiving cavity. The lifting plate 2 is connected to the box body 1 through a lifting assembly 3. A storage space is formed between the lifting plate 2 and the top wall of the receiving cavity or between adjacent lifting plates 2. Among them, the lifting assembly 3 can move along the height direction of the box body 1 to drive the lifting plate 2 to move along the height direction of the box body 1 to change the height of the storage space in the vertical direction.

[0047] In an embodiment of the present application, the lifting plate is used to support the memory. The distance between two adjacent lifting plates or the distance between the lifting plate and the bottom wall of the receiving cavity limits the size of the memory. The lifting plate is arranged in the receiving cavity of the box body through the lifting assembly, and the lifting assembly drives the lifting plate to move along the height direction of the box body to change the height of the storage space in the vertical direction. In the data storage device in the above solution, the lifting plate can be movably arranged along the height direction of the box body to change the vertical height of the storage space to place memories of different models, which helps to improve the applicability of the data storage device.

[0048] In an exemplary embodiment of the present application, the lifting assembly 3 includes a sliding assembly 31 and a limiting assembly 32. The sliding assembly 31 is connected between the lifting plate 2 and the box body 1. The sliding assembly 31 extends along the height direction of the box body 1 so that the lifting plate 2 is movably arranged relative to the box body 1 along the height direction of the box body 1. The lifting plate 2 is movably connected to the box body 1 or the sliding assembly 31 through the limiting assembly 32. By adjusting the connection state of the limiting assembly 32, the lifting plate 2 has a locked state of being stationary relative to the box body 1 and an unlocked state of being movable relative to the box body 1.

[0049] Specifically, a sliding assembly 31 is connected between the lifting plate 2 and the box body 1. The sliding assembly 31 can move the lifting plate 2 along the height direction of the box body 1, thereby adjusting the height of the object placement. The lifting plate 2 is movably connected to the box body 1 or the sliding assembly 31. By adjusting the connection state of the limiting assembly 32, the locking state and unlocking state of the lifting plate 2 can be controlled. In the locked state, the lifting plate 2 is fixedly connected to the box body 1 or the sliding assembly 31, so that the lifting plate 2 cannot move and cannot move or change its height in the vertical direction. In the unlocked state, the lifting plate 2 is allowed to move freely along the height direction of the box body 1 to adjust the height of the storage space. This design structure ensures the stability and safety of the lifting plate 2, and at the same time allows the user to freely adjust the height of the storage space, improving the flexibility and convenience of the data storage device.

[0050] Further, the sliding assembly 31 includes a rack 311 and a transmission gear 312. The rack 311 is provided on the inner wall of the accommodating cavity. The rack 311 extends along the height direction of the box body 1. The transmission gear 312 is rotatably connected to the lifting plate 2 through a first rotating shaft 313. The transmission gear 312 is meshed with the rack 311. Among them, under the drive of an external force, the transmission gear 312 can rotate relative to the lifting plate 2, so that the lifting plate 2 can move along the length direction of the rack 311.

[0051] Specifically, as Figure 1 , Figure 2 shown, there are two racks 311. The two racks 311 are spaced along the width direction of the box body 1 on the inner wall of the accommodating cavity, and the rack 311 extends along the height direction of the box body 1. A first rotating shaft 313 is provided on the side of the lifting plate 2 close to the rack 311. The first rotating shaft 313 is rotatably connected to the lifting plate 2. Correspondingly, there are two transmission gears 312. The two transmission gears 312 are respectively arranged at both ends of the first rotating shaft 313. Each transmission gear 312 is fixedly connected to the first rotating shaft 313. The two transmission gears 312 are meshed with the two racks 311 in a one-to-one correspondence. An external force pushes the lifting plate 2 to move along the height direction of the box body. The rotation of the transmission gear 312 causes the lifting plate 2 to move along the length direction of the rack 311. The transmission gear and the rack are in transmission cooperation to enable the smooth movement of the lifting plate 2. Through such a structural design, the sliding assembly 31 can effectively guide and control the vertical movement of the lifting plate 2, thereby realizing the flexible adjustment of the storage space to meet the storage requirements of different models of the memory 7.

[0052] Further, the limiting component 32 includes a first limiting member 321, a pull rod 322 and a second limiting member 323. The first limiting member 321 is arranged on the first rotating shaft 313. The pull rod 322 is slidably connected to the lifting plate 2. A second limiting member 323 is provided at one end of the pull rod 322 close to the first rotating shaft 313. An external force drives the pull rod 322 to slide relative to the lifting plate 2, so that the pull rod 322 has a first position where the second limiting member 323 cooperates with the first limiting member 321 to limit the rotation of the first rotating shaft 313 relative to the lifting plate 2, and a second position where the second limiting member 323 is separated from the first limiting member 321.

[0053] Specifically, as Figure 3 , Figure 4 shown, the first limiting member 321 is arranged on the first rotating shaft 313, and the first limiting member 321 is located between the two transmission gears 312. The pull rod 322 is slidably connected to the lifting plate 2, and the pull rod 322 is perpendicular to the first rotating shaft 313. A second limiting member 323 is provided at one end of the pull rod 322 close to the first rotating shaft 313. An external force moves the pull rod 322 to make the second limiting member 323 cooperate with or separate from the first limiting member 321. The second limiting member 323 and the first limiting member 321 cooperate together to limit the rotation of the first rotating shaft 313 relative to the lifting plate 2, and further limit the rotation of the transmission gear 312, so as to realize the locking of the lifting plate 2. When the second limiting member 323 is separated from the first limiting member 321, the first rotating shaft 313 can rotate relative to the lifting plate 2, and the rotating transmission gear 312 can drive the lifting plate 2 to move along the height direction of the box body.

[0054] Preferably, the limiting component 32 further includes a first elastic member 325. The first elastic member 325 is connected between the lifting plate 2 and the second limiting member 323. The first elastic member 325 is used to provide a restoring force for keeping the pull rod 322 in the first position. Among them, the first elastic member 325 is a spring.

[0055] In the embodiment of the present application, the first limiting member 321 is a limiting gear, the limiting gear is fixedly connected to the first rotating shaft 313, and the limiting gear is coaxially arranged with the transmission gear 312. The second limiting member 323 is an arc-shaped fork, and a clamping tooth 324 is provided on the inner wall of the arc-shaped fork. The arc-shaped fork is engaged with the limiting gear through the clamping tooth 324.

[0056] Specifically, pulling the pull rod 322 drives the second limiting member 323 to disengage from the limiting gear, and the clamping tooth 324 no longer limits the limiting gear. At this time, moving the lifting plate 2, during this process, the transmission gear 312 rotates on the rack 311. When the lifting plate 2 is adjusted to a proper position, releasing the pull rod 322, the first elastic member 325 drives the second limiting member 323 to move towards the limiting gear, so that the clamping tooth 324 is engaged with the limiting gear, thereby realizing the limitation of the limiting gear to limit the rotation of the first rotating shaft 313.

[0057] As an alternative embodiment, one of the first limiting member 321 and the second limiting member 323 is a protrusion and the other is a groove, and the protrusion and the groove are plugged into each other to limit the rotation of the first rotating shaft 313.

[0058] In another exemplary embodiment of the present application, the data storage device further includes a heat sink 4 and a heat sink assembly 5. The heat sink 4 is connected to the top surface of the lifting plate 2. A liquid cooling pipe 41 is provided on the side of the heat sink 4 away from the lifting plate 2. The heat sink assembly 5 is disposed within the accommodating cavity of the housing 1 and includes a heat exchanger 51. The liquid cooling pipe 41 is in communication with the heat exchanger 51.

[0059] Specifically, if Figure 6 As shown, the heat sink 4 is connected to the top surface of the lifting plate 2, and a liquid cooling pipe 41 is laid on the side away from the lifting plate 2. A heat sink assembly 5 is provided in the accommodating cavity of the box body 1. The heat sink assembly 5 includes a heat exchanger 51, a heat sink 52, a heat pipe 53 and a heat dissipation fan 54. The heat sink 52 and the heat pipe 53 are respectively arranged on the outside of the heat exchanger 51 to increase the heat dissipation area. A heat dissipation port is provided on the box body 1, which is connected to the accommodating cavity. A heat dissipation fan 54 is arranged at the heat dissipation port. The heat dissipation fan 54 is used to accelerate the control flow and improve the heat exchange efficiency of the heat exchanger 51. The heat sink 4 is provided to fully dissipate heat from the storage 7; the heat sink assembly 5 is provided to enhance the heat dissipation effect of the heat sink 4.

[0060] The data storage device further includes a rotating assembly 6 connected to the lifting plate 2. The rotating assembly 6 includes a rotating roller 61, which is rotatably arranged relative to the lifting plate 2 and can move toward and away from the lifting plate 2 in a predetermined direction under the action of an external force. The liquid cooling tube 41 passes through the rotating roller 61 and is connected to the heat dissipation assembly 5. The arrangement of the rotating assembly 6 ensures that the liquid cooling tube 41 is always in a tensioned state between the lifting plate 2 and the rotating roller 61, preventing the flow of coolant from being affected by bending of the liquid cooling tube 41.

[0061] Furthermore, the rotating assembly 6 includes a connecting rod 62, a telescopic rod 63, a second elastic member 64, and a second rotating shaft 65. The two connecting rods 62 are disposed on one side of the lifting plate 2, with the connecting rods 62 extending perpendicularly to the direction of movement of the lifting plate 2. The telescopic rods 63 extend along the length of the connecting rods 62. The first end of the telescopic rod 63 is connected to the connecting rod 62, and the second end of the telescopic rod 63 is provided with a connecting block 631. The second elastic member 64 is mounted on the telescopic rod 63 and connected between the connecting rod and the connecting block 631. The second rotating shaft 65 is disposed between the two connecting rods 62 and is rotatably connected to the connecting block 631. The rotating roller 61 is mounted on the exterior of the second rotating shaft 65.

[0062] Specifically, if Figure 5 、 Figure 6As shown in the figure, two connecting rods 62 are provided on the side of the lifting plate 2 away from the opening of the box body 1, and the two connecting rods 62 are arranged at intervals. Each connecting rod 62 is provided with a groove, and a telescopic rod 63 is arranged in the groove. The telescopic rod 63 extends along the length direction of the connecting rod 62. The first end of the telescopic rod 63 is connected to the inner wall of the groove, and the second end of the telescopic rod 63 is provided with a connecting block 631. The telescopic rod 63 expands and contracts along the length direction of the connecting rod 62 to enable the connecting block 631 to slide in the groove. A second elastic member 64 is sleeved on the telescopic rod 63. The second elastic member 64 is a spring. One end of the second elastic member 64 is connected to the inner wall of the groove, and the other end of the second elastic member 64 is connected to the connecting block 631. A second rotating shaft 65 is arranged between the two connecting rods 62. The second rotating shaft 65 is rotatably connected to the connecting block 631, and a rotating roller 61 is sleeved outside the second rotating shaft 65.

[0063] During the movement of the lifting plate 2, the liquid cooling pipe 41 is in contact with the rotating roller 61, and the liquid cooling pipe 41 drives the rotating roller 61 to rotate. When the liquid cooling pipe 41 applies pressure to the rotating roller 61 during the vertical upward movement of the lifting plate 2, it pushes the connecting block 631 to slide in the groove, so that the liquid cooling pipe 41 between the lifting plate 2 and the rotating roller 61 is tensioned.

[0064] Furthermore, the lifting plate 2 is slidably connected to the inner wall of the accommodating cavity through a guiding assembly. The setting of the guiding assembly makes the movement of the lifting plate 2 more stable.

[0065] Specifically, as Figure 1 、 Figure 2 shown, a sliding groove 11 is provided on the inner side wall of the box body 1. The sliding groove 11 extends along the height direction of the box body. A sliding block 21 is provided on the outer side wall of the lifting plate 2, and at least part of the sliding block 21 extends into the sliding groove 11. The sliding block 21 is slidably connected to the sliding groove 11.

[0066] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0067] 1. The lifting plate can be movably arranged along the height direction of the box body to change the vertical height of the storage space for placing memories of different models, which helps to improve the applicability of the data storage device.

[0068] 2. The setting of the rotating assembly 6 keeps the liquid cooling pipe 41 between the lifting plate 2 and the rotating roller 61 always in a tensioned state, avoiding the influence of the bending of the liquid cooling pipe 41 on the flow of the cooling liquid.

[0069] 3. The setting of the heat dissipation plate 4 enables the memory 7 to be fully cooled; the setting of the heat dissipation assembly 5 improves the heat dissipation effect of the heat dissipation plate 4.
