Furthermore, the cabinet body 1 is provided with a lead screw assembly 2 and a motor drive unit 3, the lead screw assembly 2 includes a lead screw rod 5 and a lead screw nut 4 that cooperate with each other, the output shaft of the motor drive unit 3 is connected to the lead screw rod 5 of the lead screw assembly 2, and the rotational motion of the output shaft of the motor drive unit 3 is transmitted to the lead screw rod 5, so that the rotational motion of the lead screw rod 5 is converted into the linear motion of the lead screw nut 4 through the lead screw assembly 2, and since the lifting bracket 6 is connected to the lead screw nut 4, the linear motion of the lead screw nut 4 can drive the lifting bracket 6 to move linearly, and the linear motion is a linear motion in the vertical direction. Among them, the sub-server 7 is arranged on the lifting bracket 6, so that the sub-server 7 can move linearly in the vertical direction under the drive of the lifting bracket 6, and then the sub-server 7 can move into the cavity 8 under the drive of the lifting bracket 6, and can also move the sub-server 7 out of the cavity 8 under the drive of the lifting bracket 6, so that the maintenance personnel can perform relevant maintenance on the sub-server 7.

[0042] The liquid-cooled cabinet of the present application realizes the movement of the lifting bracket 6 through the cooperation of the motor drive unit 3 and the screw assembly 2. Since the sub-server 7 is arranged on the lifting bracket 6, the rotational movement of the motor drive unit 3 is converted into the linear movement of the lifting bracket 6 along the vertical direction through the screw assembly 2, so as to drive the sub-server 7 to move into or out of the cavity 8 through the lifting bracket 6, thereby realizing the automatic lifting and lowering of the sub-server 7 in the liquid-cooled cabinet. There is no need for maintenance personnel to manually remove the sub-server 7 from the liquid-cooled cabinet, and there is no need for maintenance personnel to manually place the sub-server 7 into the liquid-cooled cabinet, which reduces the use of manpower, reduces the difficulty and risk of operation, and makes the loading and unloading maintenance process smoother and safer. For the sub-server 7 with larger size and heavier weight, the maintenance efficiency is effectively improved, and the collision of the maintenance personnel when lifting the sub-server 7 is avoided, thereby improving the safety protection performance of the sub-server 7 during the maintenance process.

[0043] In one embodiment, a first fixing frame 9 and a second fixing frame 10 are vertically arranged on the inner wall of the cavity 8, the top end of the lead screw 5 is rotatably arranged on the first fixing frame 9, and the bottom end of the lead screw 5 is rotatably arranged on the second fixing frame 10.

[0044] The lead screw 5 is rotatably arranged on the cabinet body 1. Specifically, Figure 2 and Figure 8As shown, a first fixing frame 9 and a second fixing frame 10 are arranged on the inner wall of the cavity 8 of the cabinet body 1, and the first fixing frame 9 and the second fixing frame 10 are arranged in alignment in the vertical direction, the first fixing frame 9 is arranged at the top of the cavity 8, and the second fixing frame 10 is arranged at the bottom of the cavity 8, and the lead screw 5 of the lead screw assembly 2 is arranged on the first fixing frame 9 and the second fixing frame 10, that is, the top end of the lead screw 5 is rotatably arranged on the first fixing frame 9, and the bottom end of the lead screw 5 is rotatably arranged on the second fixing frame 10. Further, corresponding bearing holes are arranged on the first fixing frame 9 and the second fixing frame 10, and bearings are installed in the bearing holes, and the top end of the lead screw 5 is arranged on the bearing on the first fixing frame 9, and the bottom end of the lead screw 5 is arranged on the bearing on the second fixing frame 10, so as to facilitate the rotation of the lead screw 5 around its axis.

[0045] The lead screw 5 of the present application is rotatably arranged on the cabinet body 1 in the vertical direction, and the top and bottom ends of the lead screw 5 are respectively arranged on the first fixed frame 9 and the second fixed frame 10, so as to convert the rotational movement of the lead screw 5 into the linear movement of the lead screw nut 4 in the vertical direction, realize the automatic lifting of the lifting bracket 6 in the vertical direction, and improve the maintenance efficiency and the safety protection performance of the sub-server 7.

[0046] In one embodiment, a transmission shaft 11 is connected to the output shaft of the motor drive unit 3 , an output gear 12 is provided on the transmission shaft 11 , a transmission gear 13 is provided at the bottom end of the lead screw 5 , and the output gear 12 is in transmission connection with the transmission gear 13 .

[0047] The motor drive unit 3 is connected to the lead screw 5 of the lead screw assembly 2 via a transmission shaft 11, so that the rotational power of the motor drive unit 3 is transmitted to the lead screw 5 via the transmission shaft 11. Specifically, Figure 7 As shown, a transmission shaft 11 is connected to the output shaft of the motor drive unit 3, an output gear 12 is provided on the transmission shaft 11, a transmission gear 13 is provided at the bottom end of the lead screw 5, the output gear 12 and the transmission gear 13 are meshed and transmission connected, and the output gear 12 and the transmission gear 13 are bevel gears. Since the axis of the lead screw 5 of the screw assembly 2 is perpendicular to the axis of the transmission shaft 11, the output gear 12 is perpendicular to the axis of the transmission shaft 11, so as to convert the rotational motion of the transmission shaft 11 around its horizontal axis into the rotational motion of the lead screw 5 around its vertical axis.

[0048] The output shaft of the motor drive unit 3 of the present application is connected to the lead screw 5 of the lead screw assembly 2 through the transmission shaft 11, so as to transmit the rotational power of the motor drive unit 3 to the lead screw 5 through the transmission shaft 11, and transmit the rotational power of the transmission shaft 11 to the lead screw 5 through the meshing transmission of the output gear 12 and the transmission gear 13, thereby realizing the automatic rotation of the lead screw 5, and further realizing the automatic lifting of the sub-server 7 on the lifting bracket 6 through the lead screw nut 4, thereby improving the maintenance efficiency and the safety protection performance of the sub-server 7.

[0049] In one embodiment, an electromagnetic clutch 14 is further included. The electromagnetic clutch 14 is disposed on the second fixing frame 10 , and an input end of the electromagnetic clutch 14 is connected to the transmission gear 13 , and an output end of the electromagnetic clutch 14 is connected to the bottom end of the lead screw 5 .

[0050] In the liquid cooling cabinet of the present application, an electromagnetic clutch 14 is provided between the transmission gear 13 and the lead screw 5 of the lead screw assembly 2 to control the engagement and separation between the transmission gear 13 and the lead screw 5. Specifically, as Figure 8 As shown, the electromagnetic clutch 14 is arranged on the second fixed frame 10, and the electromagnetic clutch 14 is arranged between the transmission gear 13 and the lead screw 5, that is, the input end of the electromagnetic clutch 14 is connected to the transmission gear 13, and the output end of the electromagnetic clutch 14 is connected to the bottom end of the lead screw 5. Therefore, due to the existence of the electromagnetic clutch 14, the lead screw 5 that needs to perform the lifting operation can be controlled by controlling the working state of the electromagnetic clutch 14.

[0051] The liquid cooling cabinet of the present application is provided with an electromagnetic clutch 14 between the transmission gear 13 and the lead screw 5 of the lead screw assembly 2 to control the engagement and separation between the transmission gear 13 and the lead screw 5. The lead screw 5 that needs to perform the lifting operation is controlled by controlling the working state of the electromagnetic clutch 14, that is, the lifting bracket 6 that specifically performs the lifting operation can be controlled, so that the sub-server 7 that needs to be lifted can be lifted, and the sub-server 7 that does not need to be lifted can remain in the liquid cooling cabinet and continue to work, thereby realizing targeted maintenance.

[0052] In one embodiment, a terminal management server 15 is disposed in the cabinet body 1 , and the terminal management server 15 is communicatively connected with the motor drive unit 3 and the electromagnetic clutch 14 .

[0053] The cabinet body 1 of the present application is provided with a terminal management server 15 to control the working state of the electromagnetic clutch 14 through the terminal management server 15. Specifically, Figure 2As shown, the terminal management server 15 is connected to the electromagnetic clutch 14 and the motor drive unit 3 in communication, so the working state of the motor drive unit 3 and the electromagnetic clutch 14 can be controlled by the terminal management server 15. Further, the terminal management server 15 can control the forward and reverse rotation of the motor drive unit 3, that is, control the forward and reverse rotation of its output shaft, and then control the forward and reverse rotation of the lead screw 5 to control the lifting and lowering of the lead screw nut 4, and then control the lifting and lowering of the sub-server 7 on the lifting bracket 6. In addition, the terminal management server 15 can control the working state of the electromagnetic clutch 14, and the electromagnetic clutch 14 includes two states of engagement and separation, that is, control whether the lead screw assembly 2 is in a working state. For example, one of the electromagnetic clutches 14 can be controlled to be in a coupled state, that is, the lead screw assembly 2 of a lifting bracket 6 is controlled to be in a working state, and the sub-server 7 of the lifting bracket 6 is lifted or lowered, or multiple electromagnetic clutches 14 can be controlled to be in a coupled state, that is, the lead screw assemblies 2 of multiple lifting brackets 6 are controlled to be in a working state, and the sub-server 7 of multiple lifting brackets 6 is lifted or lowered.

[0054] The liquid cooling cabinet of the present application is provided with an electromagnetic clutch 14 between the transmission gear 13 and the lead screw 5. By controlling the motor drive unit 3 and the electromagnetic clutch 14 through the terminal management server 15, one or more lifting brackets 6 can be controlled to perform corresponding lifting operations, and the sub-server 7 that does not require maintenance can be left in the cavity 8 to continue working, thereby realizing targeted maintenance and effectively improving maintenance efficiency.

[0055] In one embodiment, the terminal management server 15 is communicatively connected with the sub-server 7, and the terminal management server 15 includes a temperature monitoring system and a load monitoring system, the temperature monitoring system is used to obtain the temperature information of the sub-server 7, and the load monitoring system is used to obtain the load information of the sub-server 7.

[0056] like Fig. 9 As shown, the terminal management server 15 is provided with a temperature monitoring system and a load monitoring system. The terminal management server 15 is connected to the sub-server 7 so as to monitor the temperature and load of the sub-server 7 through the terminal management server 15 to perform temperature control and load balancing.

[0057] The terminal management server 15 can be used to control the data processing of the sub-server 7 to achieve load balancing. Specifically, when the sub-server 7 in the liquid cooling cabinet needs to process data, the terminal management server 15 can evenly distribute the data to multiple groups of sub-servers 7 to ensure that each sub-server 7 bears an appropriate amount of load. At the same time, the terminal management server 15 monitors the load status and temperature status inside the sub-server 7 through the data line, and displays the hardware load and temperature information on the surface of the touch screen 30 for the staff to view intuitively. When the overall load of multiple groups of sub-servers 7 is low, the terminal management server 15 centrally distributes the load to a single group of sub-servers 7, and controls the unloaded sub-servers 7 to be shut down to reduce energy consumption; the energy optimization function is realized, which facilitates the integration and distribution of the load of multiple groups of sub-servers, so that the load pressure of a single sub-server is reduced, so that it can process requests more efficiently, and reduce the additional power and heat dissipation pressure caused by high load, and at the same time facilitates the shutdown of a single group of sub-servers when the load is low, reducing energy loss.

[0058] The terminal management server 15 can be used to control the temperature of the sub-server 7 to achieve effective cooling. Specifically, when the terminal management server 15 detects that the CPU or GPU core temperature inside the sub-server 7 is high, the terminal management server 15 controls the refrigeration mechanism 31 to start, cool the fluorinated liquid, and quickly reduce the temperature of the fluorinated liquid to improve the heat dissipation efficiency of the fluorinated liquid to the sub-server 7. In addition, the terminal management server 15 controls the operation of the low-temperature cooling circulation pump, so that the low-temperature cooling circulation pump draws the fluorinated liquid with a higher temperature above the cavity 8 into the condenser 37 through the input pipe 33 for cooling. The cooled fluorinated liquid re-enters the bottom of the cavity 8 through the output pipe 34, thereby reducing the temperature of the fluorinated liquid in the cavity 8 and improving the heat dissipation effect of the liquid cooling cabinet. Among them, the fluorinated liquid transfers heat to the cooling pipeline in the condenser 37 by heat exchange to achieve cooling. When the sub-server 7 has a low load and causes the CPU or GPU core temperature to be low, the terminal management server 15 controls the refrigeration mechanism 31 to close and activates the air cooling mechanism 39 to reduce the heat dissipation efficiency and energy consumption. Specifically, when multiple groups of sub-servers 7 are running at low load, due to the low core temperature of the CPU or GPU, the terminal management server 15 controls the low-temperature cooling circulation pump to turn off and starts the worm fan 43, and extracts the heat in the cavity 8 through the heat conduction plate 40, and evenly distributes it to the inside of multiple groups of heat sink fins 41. At the same time, the high-speed rotating worm fan 43 presses the air into the inside of the air guide shell 42, so that the air flow flows quickly on the surface of the heat sink fins 41, reducing the temperature of the heat sink fins 41, thereby cooling the fluorinated liquid in the cavity 8. Therefore, the terminal management server 15 can control the liquid cooling mode and the air cooling mode to dissipate heat separately or together, allowing the heat dissipation strategy to be automatically adjusted according to the load of the sub-server, more efficiently handling the heat dissipation requirements under different workloads, avoiding performance degradation or hardware damage caused by overheating, and reducing energy consumption. Therefore, the present application can actively dissipate heat for the sub-server by establishing a refrigeration mechanism 31 and an air cooling mechanism 39, or can passively dissipate heat according to the load of the sub-server, which is beneficial to reduce the loss of heat dissipation energy. At the same time, the terminal management server 15 can monitor and allocate the sub-servers, improve the operating efficiency of the sub-servers, reduce the energy consumption of the sub-servers, and significantly reduce electricity bills, thereby reducing the company's energy expenses.

The lifting brackets 6 are provided in a linear array in the cabinet body 1, such as Figure 7 As shown, a plurality of lifting brackets 6 are arranged in a row along the width direction thereof to form a bracket row 21 . One bracket row 21 or a plurality of bracket rows 21 may be provided in a cabinet body 1 , depending on actual needs. Figure 7 The middle cabinet body 1 takes seven lifting brackets 6 to form a bracket row 21 as an example, that is, Figure 7 A total of seven lifting brackets 6 are provided, and the seven lifting brackets 6 form a bracket row 21 along the width direction thereof. Since the lifting bracket 6 needs to realize lifting and lowering movement in the cavity 8 of the cabinet body 1, one end of the lifting bracket 6 is connected to the lead screw nut 4 through the movable bracket 23, and the other end is slidably provided on the cabinet body 1 through a sliding fit, or a method such as Figure 7 In the matching mode shown, both ends of the lifting bracket 6 along its length direction are connected to the lead screw nut 4 through the movable bracket 23, that is, each lifting bracket 6 is provided with two lead screw assemblies 2, and the two lead screw assemblies 2 are respectively provided at the two ends of the lifting bracket 6. Therefore, when the lifting bracket 6 needs to be lifted or lowered, the lead screw assemblies 2 on both sides of the lifting bracket 6 need to move synchronously to realize the lifting or lowering operation of the lifting bracket 6. Therefore, a motor drive unit 3 and a transmission shaft 11 are respectively provided on both sides of the bracket row 21, as shown in FIG.

Since an electromagnetic clutch 14 is provided between each transmission gear 13 and the corresponding lead screw 5, all the electromagnetic clutches 14 can be placed in a coupled state, so that the corresponding seven lead screws 5 can be driven to rotate through a transmission shaft 11. One or more of the electromagnetic clutches 14 can also be controlled to be placed in a coupled state, and the remaining electromagnetic clutches 14 can be placed in a separated state, so that the corresponding one or more lead screws 5 can be driven to rotate through a transmission shaft 11.

The coolant can be water, mineral oil, fluorinated liquid, etc. The coolant in the cavity 8 of the cabinet body 1 of the present application takes fluorinated liquid as an example. When the temperature of the fluorinated liquid in the cavity 8 reaches a certain level, the circulating pump 36 starts to work, and the hot fluorinated liquid in the cavity 8 is extracted through the input pipe 33; then the hot fluorinated liquid is transported to the condenser 37 through the circulating pump 36; in the condenser 37, the fluorinated liquid transfers heat to the cooling pipeline by heat exchange to achieve cooling, and the cooled fluorinated liquid is then circulated to the cavity 8 through the output pipe 34.

During the operation of the refrigeration mechanism 31, the circulation pump 36 works, and the circulation pump 36 sucks the output impurity removal chamber 49 through the input pipe 33 to reduce the pressure in the output impurity removal chamber 49, so that the fluorinated liquid in the input impurity removal chamber 48 passes through the filter 47 and enters the output impurity removal chamber 49. At the same time, the foreign matter in the fluorinated liquid is filtered by the filter 47 and accumulates inside the manifold 45. The fluorinated liquid inside the chamber 8 enters the input impurity removal chamber 48 through the drain pipe 50. When too much foreign matter accumulates inside the manifold 45, part of the fluorinated liquid can be discharged together with the foreign matter by opening the first cover 53, and the filter 47 can be removed and disassembled by rotating the second cover 54 for replacement.

The slider 20 on the mounting frame 19 slides out of the slide groove 18 on the inner wall of the placement cavity 17; when the mounting frame 19 with the sub-server 7 is moved out of the placement cavity 17 of the lifting bracket 6, the motor drive unit 3 is restarted, the output shaft of the motor drive unit 3 is reversed, the output shaft of the motor drive unit 3 drives the transmission shaft 11 to reverse, the transmission shaft 11 drives the output gear 12 to reverse, the output gear 12 is meshed with the transmission gear 13, so that the transmission gear 13 is reversed, the transmission gear 13 drives the electromagnetic clutch 14 in the engaged state to reverse, the electromagnetic clutch 14 drives the corresponding lead screw 5 to reverse, the lead screw 5 cooperates with the lead screw nut 4, so that the lead screw nut 4 descends, and the lead screw nut 4 drives the lifting bracket 6 to descend, when the lifting bracket 6 is lowered into place, the motor drive unit 3 stops working and sets the corresponding electromagnetic clutch 14 to a separated state.

[0081] Embodiment 2

[0082] Reference Fig.10 As shown, Fig.10 This is a flow chart of the first method of the server lifting and lowering control method provided in an embodiment of the present application.

[0083] The server lifting and lowering control method comprises:

[0084] S101, determining a target motor drive unit from the motor drive units and a target sub-server from the sub-servers, and determining a target action corresponding to the target sub-server;

[0085] One or more liquid cooling cabinets can be set up according to actual needs. In order to control the corresponding sub-server to perform automatic lifting operations, it is necessary to first determine the sub-server that needs to perform automatic lifting and the drive that drives the sub-server to perform automatic lifting. The sub-server that needs to perform automatic lifting is called the target sub-server, and the motor drive unit that drives the target sub-server to perform automatic lifting is called the target motor drive unit. The action performed by the target sub-server is the target action, wherein the target sub-server can be one or more, which is determined according to actual conditions. Specifically, the server lifting method of the present application needs to determine the target sub-server and the target motor drive unit that drives the target sub-server, and it is necessary to determine the target action that the target sub-server needs to perform. The target action includes an ascending operation (moving out of the cavity driven by the lifting bracket) and a descending operation (moving into the cavity driven by the lifting bracket).

[0086] S102, starting the target motor drive unit according to the target action to drive the lifting bracket to move through the corresponding screw assembly, and then driving the target sub-server to perform an ascending or descending operation through the lifting bracket.

[0087] After determining the target sub-server, the target motor drive unit and the target action, it is necessary to start the target motor drive unit according to the target action. Specifically, if the target action is the rising operation of the target sub-server, the target motor drive unit needs to be controlled to rotate forward; if the target action is the descending operation of the target sub-server, the target motor drive unit needs to be controlled to reverse. Further, taking the target action as the rising operation as an example, the target motor drive unit is started so that the output shaft of the target motor drive unit rotates forward, the output shaft drives the transmission shaft connected thereto to rotate forward, the output gear is driven forward by the transmission shaft, the output gear is meshed with the transmission gear, and then the corresponding lead screw is driven forward by the transmission gear, the forward rotation of the lead screw is converted into the rising action of the lead screw nut, the lead screw nut drives the lifting bracket to rise, and then drives the target sub-server to perform the rising operation through the lifting bracket. In addition, one of the target sub-servers can perform the rising operation and the other target sub-server can perform the descending operation, and the rising or descending operations of different target sub-servers can be performed independently and synchronously.

[0088] In one embodiment, an electromagnetic clutch is provided between the output shaft of the motor drive unit and the lead screw, and the target motor drive unit is started according to the target action to drive the lifting bracket to move through the corresponding lead screw assembly, thereby driving the target sub-server to perform an ascending or descending operation through the lifting bracket, including:

[0089] Acquire and query a preset parameter table, so as to acquire a target electromagnetic clutch corresponding to the target sub-server from the preset parameter table according to the target sub-server, and set the target electromagnetic clutch to a coupled state;

[0090] An electromagnetic clutch is provided between the output shaft of the motor drive unit of the present application and the lead screw. Specifically, the output shaft of the motor drive unit is connected to the transmission shaft, and an output gear is provided on the transmission shaft. A transmission gear is provided on the lead screw of the lead screw assembly. The output gear meshes with the transmission gear to transmit the rotational power of the output shaft on the motor drive unit to the lead screw. During operation, maintenance personnel do not need to perform lifting operations on all sub-servers, but only need to perform lifting operations on one or more of the sub-servers. Therefore, an electromagnetic clutch is provided between the lead screw and the transmission gear to control the lead screw assembly corresponding to the target sub-server to perform lifting operations. Therefore, after determining the target sub-server, the target motor drive unit and the target action, it is necessary to first obtain a preset parameter table, and query the preset parameter table according to the target sub-server, so as to obtain the electromagnetic clutch corresponding to the target sub-server from the preset parameter table. Among them, the sub-servers in the liquid cooling cabinet are numbered, the lifting brackets corresponding to the sub-servers are numbered, the electromagnetic clutches of the screw assemblies corresponding to the lifting brackets are numbered, and the motor drive units corresponding to the screw assemblies are numbered, and the numbers of the sub-servers, lifting brackets, electromagnetic clutches, and motor drive units and the mapping relationship between the four are stored in a preset parameter table. When the target sub-server is determined, the corresponding electromagnetic clutch, motor drive unit and lifting bracket can be determined according to the number of the target sub-server and the preset parameter table. After determining the target electromagnetic clutch, the target electromagnetic clutch is set to a coupled state, and the electromagnetic clutches other than the target electromagnetic clutch are in a separated state, wherein the default state of all electromagnetic clutches is a separated state. In addition, when it is necessary to add a new sub-server, the new sub-server is numbered, and the mapping relationship between the number of the new sub-server and the number of the lifting bracket corresponding to the new sub-server, the number of the electromagnetic clutch, and the number of the motor drive unit is updated to the preset parameter table.

[0091] The target motor drive unit is activated according to the target action to drive the lifting bracket to move through the target electromagnetic clutch and the lead screw assembly, and then the target sub-server is driven to perform an ascending or descending operation through the lifting bracket.

[0092] After determining the target sub-server and the corresponding target motor drive unit and target electromagnetic clutch, and setting the target electromagnetic clutch to the engaged state, the target motor drive unit can be started according to the target action. Further, taking the target action as the ascending operation as an example, the target motor drive unit is started so that the output shaft of the target motor drive unit rotates forward, the output shaft drives the transmission shaft connected thereto to rotate forward, and the output gear is driven forward by the transmission shaft, and the output gear is meshed with the transmission gear. Since the target electromagnetic clutch is in the engaged state at this time, the rest of the electromagnetic clutches are in the separated state. Therefore, only the lead screw corresponding to the target sub-server rotates forward, and the forward rotation of the lead screw is converted into the ascending action of the lead screw nut, and the lead screw nut drives the corresponding lifting bracket to rise, and then drives the target sub-server to perform the ascending operation through the lifting bracket.

[0093] The liquid cooling cabinet of the present application can realize automatic lifting and lowering operations on the target sub-server, effectively improving the maintenance efficiency, avoiding collisions when maintenance personnel lift the sub-server, and improving the safety protection performance of the sub-server during the maintenance process.

Therefore, the maintenance personnel can send mobile instructions to the terminal management server through the enterprise terminal. The terminal management server receives the mobile instruction, parses the mobile instruction, and determines three information including the target sub-server, the target motor drive unit and the target action according to the mobile instruction, that is, determines the target motor drive unit from the motor drive unit and determines the target sub-server from the sub-server according to the mobile instruction, and determines the target action corresponding to the target sub-server.

Since the target electromagnetic clutch is in the engaged state at this time, and the rest of the electromagnetic clutches are in the separated state, only the lead screw corresponding to the target sub-server rotates forward, and the forward rotation of the lead screw is converted into the ascending action of the lead screw nut, and the lead screw nut drives the corresponding lifting bracket to rise, and then drives the target sub-server to perform the ascending operation through the lifting bracket.
