Description

Technical Field

[0001] This application relates to the technical field of servers, and particularly to a server cabinet structure and a server cabinet assembly method. Background Art

[0002] The server cabinet structure is a special cabinet for artificial intelligence computing, providing a standardized installation space and installation points for firmly fixing server devices. The server devices are stored in the chassis. To meet the increasing computing power requirements, the power modules of the chassis need to be frequently replaced; during the execution of the analysis algorithm by the server devices, it may be necessary to quickly replace the faulty power system in extreme environments. Therefore, the assembly efficiency of the chassis and the cabinet directly affects the operating efficiency of the server devices.

[0003] The existing chassis is positioned in the cabinet by relying on a high-precision guiding method. Usually, the chassis is connected to the cabinet through pins. Due to manufacturing tolerances, assembly errors, or long-term wear in the high-precision guiding design, the pins are misaligned, resulting in pin deformation or poor contact. The existing chassis can also be connected to the cabinet through spring lock tongues. Due to the elastic cooperation between the spring lock tongues and the cabinet, in the case of high-frequency vibration of the cabinet, the problems of insufficient locking force or fatigue failure of the spring lock tongues lead to loosening between the chassis and the cabinet; whether it is pin positioning or spring lock tongue positioning of the chassis, the reliability of the assembly of the chassis and the cabinet is insufficient, which affects the safe operation of the server devices. Summary of the Invention

[0004] The purpose of this application is to solve the above technical problems, and to provide a server cabinet structure and a server cabinet assembly method, so as to ensure the reliability of the assembly of the chassis and the cabinet, improve the anti-vibration performance of the cabinet, and avoid the loosening problem after the assembly of the chassis and the cabinet. To achieve the above purpose, the technical solution of this application is as follows: In the first aspect, this application provides a server cabinet structure, including a cabinet and a chassis. The cabinet has a receiving cavity, and a limiting portion for guiding the arrangement direction of the chassis is provided on the inner wall of the receiving cavity. A positioning assembly is provided on the chassis. The positioning assembly includes a support seat, an adjusting member, a linkage structure, and a positioning member. The support seat is connected to the chassis. The adjusting member and the positioning member are both provided on the support seat. The adjusting member and the positioning member are interconnected through the linkage structure to convert the rotational movement of the adjusting member into a linear movement of the positioning member. One end of the chassis abuts against the limiting portion, and the other end of the chassis is connected to the inner wall of the receiving cavity through the positioning member.

[0005] In a second aspect, the present application provides a method for assembling a server cabinet body, which is applied to the above-mentioned server cabinet body structure. A first sensor is provided on the self-locking structure, and the first sensor is used to detect a first locking signal indicating that the self-locking structure is connected in place. A second sensor is provided on the mating part, and the second sensor is used to detect a second locking signal indicating that the positioning part is connected to the mating part in place. The method includes: installing the chassis into the cabinet; connecting one end of the chassis to the cabinet through the self-locking structure and obtaining the first locking signal; controlling the positioning part to move in a direction perpendicular to the force-bearing direction of the self-locking structure according to the first locking signal, connecting the other end of the chassis to the mating part through the positioning part, and obtaining the second locking signal; starting the operation of the chassis according to the second locking signal; determining whether the operating state of the chassis is normal. If the operating state of the chassis is normal, then cover the cover on the side wall of the cabinet. If the chassis operates abnormally, then unlock the chassis for maintenance.

[0006] Compared with the prior art, the beneficial effects of the server cabinet body structure and the server cabinet body assembly method of the present application are mainly reflected in: The chassis can be accurately installed into the accommodating cavity along the guidance of the limiting part. One end of the chassis is positioned by the limiting part, and the other end of the chassis is positioned by the positioning component, so that both ends of the chassis are accurately positioned in the cabinet, avoiding the situation of the chassis moving and deviating. Even in an environment with high-frequency vibration, the chassis and the cabinet still maintain good connection performance, ensuring that the chassis can be in a stable operating state, thereby improving the service durability of the server cabinet body structure.

[0007] The positioning component is arranged at the end of the chassis, which is beneficial to operating the positioning component. The rotation adjusting part can drive the positioning part to move. The positioning part is connected to the inner wall of the accommodating cavity, improving the convenience of operation; the linear movement stroke of the positioning part can be accurately controlled by rotating the adjusting part, effectively reducing the complexity of the layout of the positioning component, avoiding the situation that the driving stroke of the positioning part is too long and occupying the space of the accommodating cavity, and realizing accurate control of the operating stroke of the positioning part.

[0008] The server cabinet body assembly method is applicable to the server cabinet body structure. When the chassis is assembled in place in the server cabinet body structure, the operating state of the chassis can be effectively judged, excluding the interference factor of the chassis not being positioned in place, quickly positioning to the chassis with operating problems, improving the accuracy of chassis assembly and the safety of chassis operation.

[0012] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0013] Embodiment 1 This embodiment provides a server cabinet structure, including a cabinet 1 and a chassis 2. The cabinet 1 has a receiving cavity 11 for storing the chassis 2. Due to the insufficient anti-vibration performance of the traditional chassis 2 and the cabinet 1, the reliability during long-term use is reduced, and loosening problems are likely to occur. At the same time, there is a lack of detection of the positioning state during the assembly of the server cabinet structure, relying on manual judgment whether the server cabinet structure is assembled in place, resulting in misjudgment situations, increasing the risk of the server system operation. In order to improve the reliability of the assembly of the cabinet 1 and the chassis 2 and ensure that the chassis 2 is accurately assembled in the cabinet 1, this embodiment improves the server cabinet structure, so that the server cabinet structure still maintains good connection performance and operating state in a high-frequency vibration environment. The following is a detailed description.

[0014] As Figures 1-5 shown, a limiting portion 12 for guiding the arrangement direction of the chassis 2 is provided on the inner wall of the receiving cavity 11. A positioning component 21 is provided on the chassis 2. The positioning component 21 includes a bracket seat 31, an adjusting member 32, a linkage structure 33, and a positioning member 34. The bracket seat 31 is connected to the chassis 2. The adjusting member 32 and the positioning member 34 are both provided on the bracket seat 31. The adjusting member 32 and the positioning member 34 are interconnected through the linkage structure 33 to convert the rotational movement of the adjusting member 32 into a linear movement of the positioning member 34. One end of the chassis 2 abuts against the limiting portion 12, and the other end of the chassis 2 is connected to the inner wall of the receiving cavity 11 through the positioning member 34.

[0015] Among them, the cabinet 1 can be in a substantially rectangular parallelepiped structure. One end of the cabinet 1 in the width direction is the opening of the receiving cavity 11, and the other end is the bottom of the receiving cavity 11. Both ends of the cabinet 1 in the length direction are side walls. The opening of the receiving cavity 11 can be located on the side wall of the cabinet 1. Correspondingly, if the opening of the receiving cavity 11 is arranged upward, the opening of the receiving cavity 11 is located on the top wall of the cabinet 1. The orientation of the opening of the receiving cavity 11 can be adaptively selected according to the actual installation position of the cabinet 1.

[0016] The chassis 2 can be accurately inserted into the receiving cavity 11 along the guidance of the limiting portion 12. One end of the chassis 2 is positioned by the limiting portion 12, and the other end of the chassis 2 is positioned by the positioning component 21. Among them, the positioning member 34 moves in a direction perpendicular to the force application direction of one end of the chassis 2 and the limiting portion 12, so that both ends of the chassis 2 are accurately positioned in the cabinet 1, avoiding the situation of the chassis 2 moving and deviating. Even in a high-frequency vibration environment, the chassis 2 and the cabinet 1 still maintain good connection performance, ensuring that the chassis 2 can be in a stable operating state, thereby improving the service durability of the server cabinet structure.

[0017] The positioning component 21 is arranged at the end of the chassis 2, which is beneficial to operating the positioning component 21. Rotating the adjusting member 32 can drive the positioning member 34 to move. The transmission mode of the positioning component 21 has good anti-vibration performance, and the positioning member 34 is not easily separated from the inner wall of the accommodating cavity 11. The connection between the positioning member 34 and the inner wall of the accommodating cavity 11 can also improve the convenience of operation. By rotating the adjusting member 32, the linear movement stroke of the positioning member 34 can be accurately controlled, effectively reducing the complexity of the layout of the positioning component 21, avoiding the situation that the driven stroke of the positioning member 34 is too long and occupying the space of the accommodating cavity 11, and achieving precise control of the operating stroke of the positioning member 34.

[0018] In one embodiment, the limiting portion 12 is arranged on the top wall and / or the bottom wall of the accommodating cavity 11, and the limiting portion 12 extends from the opening of the accommodating cavity 11 towards the cavity bottom of the accommodating cavity 11.

[0019] In other embodiments, the limiting portion 12 can also be arranged on the side wall of the accommodating cavity 11. The chassis 2 is arranged according to the opening direction of the accommodating cavity 11. The chassis 2 enters the cabinet 1 from the opening position of the accommodating cavity 11 and is arranged towards the cavity bottom of the accommodating cavity 11.

[0020] In this embodiment, the limiting portion 12 is arranged on the top wall and the bottom wall of the accommodating cavity 11, and the opening of the accommodating cavity 11 is located on one side wall of the cabinet 1. Specifically, the limiting portion 12 extends from the opening of the accommodating cavity 11 towards the cavity bottom of the accommodating cavity 11. The number of the limiting portions 12 can be multiple, and a plurality of limiting portions 12 are arranged at equal intervals along the length direction of the cabinet 1 in the accommodating cavity 11. Each limiting portion 12 can be used to guide the chassis 2. The number of the limiting portions 12 is reasonably arranged according to the size of the accommodating space of the accommodating cavity 11. On the one hand, it is necessary to ensure that the chassis 2 can be easily loaded, and on the other hand, it is necessary to ensure that the air blower 62 can effectively supply air circulation to the accommodating cavity 11 to achieve the effect of timely cooling the chassis 2.

[0021] In other embodiments, the limiting portion 12 can be in a U-shaped structure, the limiting portion 12 protrudes from the top wall and / or the bottom wall of the accommodating cavity 11, and the opening of the U-shaped structure is in the same direction as the opening of the accommodating cavity 11. When the chassis 2 enters the accommodating cavity 11, the side wall of the chassis 2 is inserted along the contour shape of the U-shaped structure until the end of the chassis 2 is completely clamped with the U-shaped structure, thereby limiting the position of the chassis 2 in the length direction of the cabinet 1 and avoiding the problem of the chassis 2 shaking in the length direction of the cabinet 1.

[0022] In one embodiment, a sliding groove 13 is arranged on the limiting portion 12. The sliding groove 13 is arranged in the same direction as the limiting portion 12 and is connected to the opening of the accommodating cavity 11. A sliding portion 22 is arranged on the chassis 2, and the sliding portion 22 is arranged corresponding to the sliding groove 13.

[0023] Such as Figure 2 、 Figure 5As shown, since the limiting portion 12 is arranged on the top wall and / or the bottom wall of the accommodating cavity 11, a sliding groove 13 is arranged on the limiting portion 12, and the sliding groove 13 can also be located on the top wall and / or the bottom wall of the accommodating cavity 11. One end of the sliding groove 13 is a closed end, and the other end of the sliding groove 13 is an open end, which is connected to the opening of the accommodating cavity 11, so that the chassis 2 can smoothly enter the cabinet 1 from the end of the sliding groove 13.

[0024] Correspondingly, a sliding portion 22 is provided on the top and / or bottom of the chassis 2, and the sliding portion 22 is adapted to the sliding groove 13, so that the chassis 2 can be accurately guided along the sliding portion 22, reducing the difficulty of positioning the chassis 2 into the cabinet 1.

[0025] In one embodiment, the limiting portion 12 is recessed relative to the inner wall of the accommodating cavity 11, the positioning assembly 21 is located at one end of the chassis 2 facing the opening of the accommodating cavity 11, and the other end of the chassis 2 abuts against the end of the limiting portion 12 away from the opening of the accommodating cavity 11.

[0026] Exemplarily, the chassis 2 is a roughly rectangular plate structure, and the chassis 2 and the cabinet 1 are positioned by plugging; wherein, the limiting portion 12 may be a groove structure, one end of the groove structure is a closed end, and the other end of the groove structure is an open end, and the open end is connected to the opening of the accommodating cavity 11, so that the chassis 2 can accurately enter the cabinet 1 through the guidance of the limiting portion 12, and abut against the closed end of the limiting portion 12. When the limiting portion 12 is a groove structure, the limiting portion 12 is similar in structure to the sliding groove 13, and it can be understood that the sliding groove 13 is arranged inside the groove structure and is recessed relative to the groove structure; the sliding groove 13 is arranged on the limiting portion 12, so that the chassis 2 cooperates with the sliding groove 13, so that the chassis 2 is further accurately positioned, and the shaking problem of the chassis 2 in the limiting portion 12 is avoided.

[0027] In one embodiment, the positioning member 34 is disposed on the top and / or bottom of the bracket seat 31 , and a matching portion 14 is disposed on the inner wall of the accommodating cavity 11 , and the positioning member 34 is correspondingly connected to the matching portion 14 .

[0028] For example, Figure 4 , Figure 5As shown, the positioning members 34 are arranged at the top and bottom of the support base 31. The mating portion 14 can be a hole position. The mating portion 14 is arranged on the limiting portion 12. The positioning members 34 are correspondingly inserted and fixed with the mating portion 14. After the chassis 2 moves in place on the limiting portion 12, by adjusting the positioning assembly 21, the positioning members 34 are moved to the mating portion 14. One end of the chassis 2 abuts against the limiting portion 12, and the other end of the chassis 2 is connected to the mating portion 14 through the positioning members 34. At the same time, the chassis 2 is guided and positioned along the limiting portion 12, so that the chassis 2 is positioned in both the length direction and the width direction of the cabinet 1, ensuring the accuracy and stability of the installation of the chassis 2, and enabling the chassis 2 to cope with the environment of high-frequency vibration without misalignment movement.

[0029] Exemplarily, a second sensor is arranged in the mating portion 14. The second sensor is used to detect whether the positioning member 34 is connected to the mating portion 14 in place. When the positioning member 34 is connected to the mating portion 14 in place, a second locking signal can be triggered. The locking state of the positioning member 34 can be determined through the second locking signal, which is convenient for effectively monitoring the assembly situation of the chassis 2. If there is a situation where the positioning member 34 cannot be locked with the mating portion 14, the problem can also be discovered in time and the chassis 2 can be repaired.

[0030] In one of the implementation manners, both the adjusting member 32 and the positioning member 34 movably penetrate through the support base 31. The adjusting member 32 is located in the middle of the support base 31. An internal space for accommodating the linkage structure 33 is formed between the support base 31 and the chassis 2. The positioning members 34 are located at the top and bottom of the support base 31. The support base 31 is provided with positioning ports 35 for guiding the positioning members 34. The adjusting member 32 rotates relative to the support base 31 to drive the linkage structure 33 to synchronously drive the oppositely arranged positioning members 34 to move towards each other or move in the opposite direction.

[0031] In order to improve the stability of the connection between the positioning member 34 and the inner wall of the accommodating cavity 11, the positioning assembly 21 includes two positioning members 34 that move synchronously towards each other or move in the opposite direction. The positioning members 34 move into the limiting portion 12 and are positioned in the mating portion 14 to achieve locking, and the positioning members 34 move out of the limiting portion 12 to achieve unlocking. The rotational movement of the adjusting member 32 can be operated by an automated device or manually.

[0032] Exemplarily, as Figure 5 、 Figure 6 shown, the two positioning members 34 are symmetrically arranged relative to the position where the adjusting member 32 is located. The adjusting member 32 can synchronously adjust the two positioning members 34, so that the two positioning members 34 can move the same distance synchronously, which is beneficial for the two positioning members 34 to be synchronously positioned on the inner wall of the accommodating cavity 11 and maintain the stability of the connection between the chassis 2 and the inner wall of the accommodating cavity 11.

[0033] In one of the embodiments, the linkage structure 33 includes a connecting rod 41 and movable rods 42 disposed at both ends of the connecting rod 41. One end of the movable rod 42 is rotatably connected to the connecting rod 41, and the other end of the movable rod 42 is rotatably connected to the positioning member 34; the adjusting member 32 drives the connecting rod 41 to approach or move away from the positioning port 35, so that the positioning member 34 moves in the positioning port 35.

[0034] Exemplarily, one end of the movable rod 42 is hinged to the connecting rod 41, and the other end of the movable rod 42 is hinged to the positioning member 34; specifically, first hinge grooves are provided at both ends of the connecting rod 41, and a second hinge groove is provided at the end of the positioning member 34 facing the connecting rod 41. Both the first hinge groove and the second hinge groove are substantially U-shaped structures. Both ends of the movable rod 42 are pivotally connected to the first hinge groove and the second hinge groove respectively. The first hinge groove and the second hinge groove have a guiding effect on the rotation direction and angle of the movable rod 42, ensuring that the movable rod 42 moves under certain rotation direction and angle conditions, avoiding movement deviation of the movable rod 42 due to lack of guidance, and effectively improving the moving accuracy of the positioning member 34.

[0035] In order to achieve the flexibility of the rotation of the movable rod 42, both ends of the movable rod 42 are arc-shaped structures, reducing the rotational friction between the movable rod 42 and the first hinge groove and the second hinge groove, so that the movable rod 42 can flexibly adjust the angle.

[0036] The positioning member 34 is adapted to the positioning port 35. The positioning port 35 is located above and below the connecting rod 41. When the connecting rod 41 moves along the width direction of the cabinet 1, during the process of the connecting rod 41 approaching the positioning port 35, the connecting rod 41 drives the movable rod 42 to rotate at the hinge point. Due to the guiding effect of the positioning port 35 on the positioning member 34, the positioning member 34 is pushed out from the internal space of the support base 31 to the external space along the height direction of the cabinet 1, realizing the locking of the two positioning members 34 to the top wall and the bottom wall of the accommodating cavity 11 respectively; during the process of the connecting rod 41 moving away from the positioning port 35, the connecting rod 41 drives the movable rod 42 to rotate at the hinge point, and the positioning member 34 retracts from the external space of the support base 31 to the internal space along the height direction of the cabinet 1, realizing the unlocking of the two positioning members 34 from the top wall and the bottom wall of the accommodating cavity 11 respectively.

[0037] In one of the embodiments, part of the adjusting member 32 has a thread, and the adjusting member 32 is threadedly connected to the support base 31; the adjusting member 32 passes through the connecting rod 41, and a step portion 43 that movably abuts against both sides of the connecting rod 41 is provided on the adjusting member 32.

[0038] Exemplarily, as Figure 6As shown, the part of the adjusting member 32 passing through the support base 31 has a thread, and a threaded hole 37 corresponding to the adjusting member 32 is provided on the support base 31. The part of the adjusting member 32 passing through the connecting rod 41 is a round rod structure. The rotation of the round rod structure does not affect the connecting rod 41. By rotating the adjusting member 32, it moves relative to the support base 31 in the width direction of the cabinet 1. Furthermore, the stepped portion 43 can drive the connecting rod 41 to move in the width direction of the cabinet 1. Among them, gaps are left between the stepped portion 43 and both sides of the connecting rod 41, enabling the adjusting member 32 to move flexibly in the connecting rod 41, preventing the stepped portion 43 from being in close contact with the connecting rod 41 and causing rotational interference to the connecting rod 41; the stepped portion 43 is equivalent to the shoulder of the connecting rod 41, and the stepped portion 43 and the connecting rod 41 are integrally formed.

[0039] To facilitate the rotational movement of the adjusting member 32 relative to the support base 31, a knob portion is provided at the end of the adjusting member 32 facing away from the chassis 2. The knob portion is conducive to rotational operation and accurately controls the moving stroke of the adjusting member 32 in the width direction of the cabinet 1.

[0040] A guiding hole 38 for supporting the adjusting member 32 is provided on the chassis 2. The guiding hole 38 and the threaded hole 37 are in the same straight line direction. The adjusting member 32 extends into the guiding hole 38 and rotates in the guiding hole 38. The rotation of the adjusting member 32 does not affect the chassis 2. The part of the adjusting member 32 extending into the guiding hole 38 can be a round rod structure or have a thread. The guiding hole 38 is adapted to the adjusting member 32. The guiding hole 38 effectively supports the adjusting member 32 to move effectively in the straight line direction, and at the same time enables the adjusting member 32 to effectively support the connecting rod 41, and the connecting rod 41 hangs on the adjusting member 32 without rotating.

[0041] In one implementation, the linkage structure 33 includes screws 44 arranged at intervals. The positioning member 34 and the screws 44 form a kinematic pair through a thread pair; a main bevel gear 45 is provided on the adjusting member 32, and driven bevel gears 46 are respectively provided at the opposite ends of the two screws 44. The main bevel gear 45 drives the driven bevel gears 46 to rotate, so as to convert the rotational movement of the screws 44 into the linear movement of the positioning member 34.

[0042] As Figure 7 shown, the component composition of the linkage structure 33 can be various. Its function is to convert the rotational movement of the adjusting member 32 into the linear movement of the positioning member 34; the two screws 44 can be driven by the adjusting member 32 to rotate synchronously. During the rotation of the screws 44, the positioning member 34 is driven to move up and down. At the same time, the positioning member 34 is guided by the positioning port 35 to ensure the stability of the kinematic pair formed by the positioning member 34 and the screws 44 and improve the moving accuracy of the positioning member 34. Similarly, the two positioning members 34 can move synchronously, and the two positioning members 34 are accurately positioned on the top wall and the bottom wall of the accommodating cavity 11.

[0043] When the positioning member 34 forms a kinematic pair with the screw 44, at this time, the adjusting member 32 does not need to cooperate with the guiding hole 38 on the chassis 2. One end of the adjusting member 32 is provided with a main bevel gear 45, and the other end of the adjusting member 32 extends out of the support seat 31; at this time, the part of the adjusting member 32 passing through the support seat 31 is a round rod structure, and the adjusting member 32 only realizes rotational movement without horizontal movement. When the adjusting member 32 rotates, the main bevel gear 45 rotates synchronously, and then the main bevel gear 45 drives two driven bevel gears 46 to rotate synchronously. The two driven bevel gears 46 rotate relative to each other, so that the two positioning members 34 can realize synchronous movement and the moving distances are equal.

[0044] In one embodiment, the support seat 31 and / or the chassis 2 is provided with a support member 47 for supporting the screw 44, and the screw 44 is rotatably arranged relative to the support member 47.

[0045] As Figure 7 shown, in order to ensure the stability of the installation position of the screw 44, a plurality of support members 47 are arranged at the end of the chassis 2. In this embodiment, the support members 47 are installed in one-to-one correspondence with the screw 44, and a bearing is arranged between the support member 47 and the screw 44. The rotational movement of the screw 44 does not affect the support member 47, and the support member 47 effectively supports the screw 44 to maintain the stability of the rotational movement of the screw 44.

[0046] In one embodiment, a hanging portion 36 is arranged at the end of the positioning member 34 departing from the linkage structure 33. The size of the hanging portion 36 is larger than the size of the positioning opening 35, and the hanging portion 36 is located in the external space of the support seat 31.

[0047] Exemplarily, as Figure 6 、 Figure 7 shown, the positioning member 34 can be in a substantially L-shaped structure, and the hanging portion 36 is located above and / or below the support seat 31. Among them, the positioning opening 35 can be a square through opening. When the positioning member 34 retracts from the external space of the support seat 31 to the internal space, the hanging portion 36 abuts against the support seat 31 movably for limiting, so as to prevent the positioning member 34 from completely disengaging from the positioning opening 35, resulting in the positioning opening 35 being unable to guide the positioning member 34 again. The size of the positioning member 34 is adapted to the size of the positioning opening 35, so that the positioning opening 35 can accurately guide the positioning member 34 to move in a straight line, avoiding the problem that the positioning member 34 is deflected when being driven and unable to be connected to the mating portion 14.

[0048] In one embodiment, the bottom of the accommodation cavity 11 and the end of the chassis 2 facing the bottom of the accommodation cavity 11 are connected by a self-locking structure 23, and the self-locking structure 23 is arranged to communicate with the liquid cooling system.

[0049] Exemplarily, as Figure 4 、 Figure 5As shown, a plug-in part 51 is provided at the bottom of the accommodation cavity 11, and one end of the chassis 2 facing the bottom of the accommodation cavity 11 is provided with a mating part 52. The plug-in part 51 is correspondingly connected to the mating part 52; the plug-in part 51 is arranged to communicate with the liquid cooling system.

[0050] Specifically, the grouped plug-in parts 51 are arranged at equal intervals along the length direction of the cabinet 1. The number of a group of plug-in parts 51 is two. One plug-in part 51 can be the coolant inlet of the liquid cooling system and is located above the bottom of the accommodation cavity 11; the other plug-in part 51 can be the coolant outlet of the liquid cooling system and is located below the bottom of the accommodation cavity 11; the number of groups of the plug-in parts 51 corresponds to the number of the chassis 2, and each group of plug-in parts 51 is correspondingly connected to the chassis 2. Correspondingly, the end of the chassis 2 is provided with a mating part 52. The grouped mating parts 52 are arranged at intervals on the chassis 2. The number of a group of mating parts 52 is two. A group of mating parts 52 is connected to a group of plug-in parts 51 in a one-to-one correspondence. Among them, one mating part 52 can be the coolant inlet of the chassis 2, and the other mating part 52 can be the coolant outlet of the chassis 2. Thus, when the plug-in part 51 and the mating part 52 are correspondingly connected in place, the liquid cooling system can effectively circulate the coolant in the chassis 2.

[0051] When the chassis 2 is installed in the cabinet 1, when the end of the chassis 2 abuts against the limiting part 12, the plug-in part 51 and the mating part 52 are connected in place, so that the coolant of the liquid cooling system can smoothly enter the chassis 2; a first sensor (not shown in the figure) is provided on the self-locking structure 23. The first sensor is used to detect whether the self-locking structure 23 is connected in place, so as to ensure the connection of the liquid cooling system. When the self-locking structure 23 is connected in place, a first locking signal can be triggered through the first sensor. According to the first locking signal, the connection state of the chassis 2 and the cabinet 1 can be judged. If the self-locking structure 23 is not connected in place, maintenance can be carried out in time.

[0052] Among them, both the first sensor and the second sensor are electronic sensors, commonly microswitches. For example, when the self-locking structure 23 is connected, physical pressure is applied to the switch contacts to output an electrical signal, enabling the first sensor to respond quickly. It can also be a magnetic sensor. For example, a magnet and a Hall sensor are embedded in the self-locking structure 23. When the self-locking structure 23 is connected, the magnetic field triggers the output of a signal, enabling the first sensor to respond without physical contact. It can also be an optical sensor. For example, an infrared emitter and an infrared receiver are installed in the self-locking structure 23. When the self-locking structure 23 is connected, the reflected light path is blocked to trigger a signal, enabling the first sensor to respond with high precision. It can also be a pressure sensor. For example, a pressure sensor is installed in the self-locking structure 23. When the self-locking structure 23 is connected, the pressure sensor reaches a preset value, which is the pressure value when the self-locking structure 23 is connected in place, to determine whether the self-locking structure 23 is connected in place. Similarly, the types of sensors applicable to the above self-locking structure 23 are also applicable when the positioning member 34 is connected to the mating portion 14, and no further examples are given here.

[0053] In one of the embodiments, the server cabinet structure further includes a heat dissipation part 61 and a blower 62. The heat dissipation part 61 is arranged on the opposite inner walls of the accommodation cavity 11. A heat dissipation air duct 63 corresponding to the chassis 2 is formed on the heat dissipation part 61. The blower 62 is communicated with the heat dissipation air duct 63 to enable the opposite heat dissipation air ducts 63 to form a convection wind.

[0054] Exemplarily, as Figure 4 shown, the heat dissipation part 61 is located on the inner walls at both ends along the length direction of the cabinet 1. The number of the heat dissipation parts 61 can be multiple. One end of the heat dissipation part 61 extends towards the opening of the accommodation cavity 11, and the other end extends towards the bottom of the accommodation cavity 11. The multiple heat dissipation parts 61 are arranged at intervals on the inner wall of the accommodation cavity 11. A heat dissipation air duct 63 is formed between adjacent heat dissipation parts 61. The heat dissipation air duct 63 corresponds to both ends of the chassis 2 along the width direction of the cabinet 1. Furthermore, the airflow discharged through the guiding of the heat dissipation air duct 63 can form a convection wind in the space corresponding to the opening and the space corresponding to the bottom of the accommodation cavity 11, effectively cooling the accommodation cavity 11.

[0055] Exemplarily, the heat dissipation part 61 can be in a substantially L-shaped structure. The end of the heat dissipation part 61 extends towards the bottom of the accommodation cavity 11, making the heat dissipation part 61 closer to the self-locking structure 23 and directly guiding the airflow discharged from the heat dissipation air duct 63 to the self-locking structure 23.

[0057] A filter screen 66 is provided on the window 65, and the filter screen 66 covers the air blower 62, so that the filtered air flow is sent into the air blower 62, reducing impurities or pollutants from entering the accommodation cavity 11 and improving the operating safety of the chassis 2. The filter screen 66 can be set as a multi-layer structure for realizing multi-effect air filtration operation, making the gas entering the accommodation cavity 11 cleaner, avoiding impurities or pollutants from adhering to the air blower 62, and further reducing the frequency of cleaning the air blower 62 and the accommodation cavity 11.

[0058] Exemplarily, an end of the chassis 2 facing the bottom of the accommodation cavity 11 is provided with a power interface (not shown in the figure). Correspondingly, a power socket (not shown in the figure) is provided at the bottom of the accommodation cavity 11, and the power interface is docked with the power socket to realize the connection between the chassis 2 and the power supply system.

[0059] Specifically, the air blower 62 can be a fan, and the fan can be completely embedded in the window 65, and the air blower 62 is communicated with the accommodation cavity 11 to enable the heat dissipation part 61 to perform effective air guiding operation.

[0060] In one embodiment, the server cabinet structure further includes a cover plate 7. The cover plate 7 corresponds to the opening of the accommodation cavity 11. A docking component is provided between the cover plate 7 and the cabinet 1. The docking component includes a first docking structure 71 and a second docking structure 72. The top of the cover plate 7 and the top of the cabinet 1 are elastically connected through the first docking structure 71, and the side wall of the cover plate 7 and the side wall of the cabinet 1 are movably connected through the second docking structure 72.

[0063] Exemplarily, a handle is provided on the cover plate 7 for conveniently removing or installing the cover plate 7 on the cabinet 1; the handle is located on the side of the cover plate 7 facing away from the cabinet 1.

[0064] Embodiment 2 This embodiment provides a server cabinet assembly method, which is applied to the server cabinet structure in the above embodiment. The server cabinet structure is assembled by the server cabinet assembly method to achieve reliability of the server cabinet structure.

[0065] The cabinet 1 and the chassis 2 are connected via a self-locking structure 23, on which a first sensor is provided, and which is used to detect a first locking signal when the self-locking structure 23 is connected into place; specifically, the first sensor can be provided on the plug-in portion 51, or on the plug-in portion 52, and when the self-locking structure 23 is connected into place, a first locking signal is triggered, and the first locking signal can be transmitted to the chassis operation control system.

[0066] A second sensor is provided on the mating part 14, and the second sensor is used to detect a second locking signal when the positioning member 34 and the mating part 14 are connected in place; when the positioning member 34 and the mating part 14 abut against each other, the second locking signal is triggered, and the second locking signal can be transmitted to the chassis operation control system.

[0067] The server cabinet assembly method specifically includes: S1, chassis 2 is installed into cabinet 1; The chassis 2 is installed into the cabinet 1 through the guidance of the limiting portion 12 , so that the end of the chassis 2 facing the bottom of the accommodating cavity 11 abuts against the limiting portion 12 , and the chassis 2 is positioned in the length direction of the cabinet 1 .

[0068] S2. One end of the chassis 2 is connected to the cabinet 1 through a self-locking structure 23 to obtain a first locking signal. The self-locking structure 23 includes a plugging part 51 and a mating part 52. When the plugging part 51 is connected to the mating part 52 in place, it can be mechanically and automatically locked. It is understood that when the self-locking structure 23 is locked, the plugging part 51 and the mating part 52 are tightly plugged, which can effectively seal the coolant transmitted by the liquid cooling system without leakage of the coolant in the self-locking structure 23.

[0069] When the end of the chassis 2 abuts against the limiting part 12 in place, the plugging part 51 abuts against the mating part 52, and the first sensor triggers the first locking signal. The chassis operation control system obtains the first locking signal. If the first sensor cannot trigger the first locking signal, the self-locking structure 23 is in a situation where it is not connected in place, and the installation position of the chassis 2 needs to be repaired.

[0070] S3. According to the first locking signal, control the positioning member 34 to move in the direction perpendicular to the force-bearing direction of the self-locking structure 23. The other end of the chassis 2 is connected to the mating part 14 through the positioning member 34 to obtain a second locking signal. After the chassis operation control system obtains the first locking signal, it indicates that the end of the chassis 2 facing the bottom of the accommodating cavity 11 has been connected in place, and then control the positioning member 34 to be connected to the mating part 14 again. When the other end of the chassis 2 is connected to the mating part 14 through the positioning member 34 in place, the second sensor triggers the second locking signal, and the chassis operation control system obtains the second locking signal.

[0071] The force-bearing direction of the self-locking structure 23 is relatively perpendicular to the moving direction of the positioning member 34, thereby realizing the positioning of the chassis 2 in the width direction and height direction of the cabinet 1. If the second sensor cannot trigger the second locking signal, the positioning member 34 is in a situation where it is not connected in place, and the installation position of the chassis 2 needs to be repaired.

[0072] Since the number of chassis 2 is large, and a first sensor and a second sensor are arranged at the installation position of each chassis 2. Once the chassis 2 has a positioning deviation, the chassis operation control system can accurately locate the chassis 2 with the positioning deviation problem according to the feedback of the first sensor and the second sensor. Therefore, during the positioning process at both ends of the chassis 2, any end of the chassis 2 with a positioning deviation can be detected in time, greatly improving the assembly efficiency of the chassis 2 and the efficiency of identifying that the chassis 2 is not installed in place.

[0073] S4. According to the second locking signal, the chassis 2 starts to operate, including operating the power supply system and the liquid cooling system. The chassis operation control system controls the power supply system and the liquid cooling system to start according to the second locking signal, so that the chassis 2 starts to operate. The chassis 2 starts to operate only after it is ensured to be in place at the assembly position in the cabinet 1, which improves the safety of the normal operation of the chassis 2.

[0074] S5. Determine whether the operation status of the chassis 2 is normal. If the operation status of the chassis 2 is normal, cover the cover plate 7 on the side wall of the cabinet 1. If the chassis 2 operates abnormally, unlock the chassis 2 for maintenance.

[0075] The chassis operation control system determines whether the operation status of the chassis 2 is normal. If the operation status of the chassis 2 is normal, the power supply system can power on the chassis 2 normally, and the liquid cooling system can supply coolant to the chassis 2 normally, which means that the chassis 2 does not need to be replaced and repaired temporarily, then connect the cover plate 7 to the side wall of the cabinet 1.

[0076] If the chassis 2 operates abnormally, it means that there may be problems with the internal components of the chassis 2. Excluding the factor that the chassis 2 and the cabinet 1 are not positioned properly, the chassis 2 can be removed from the cabinet 1 for maintenance.

[0077] The server cabinet assembly method of this embodiment is applicable to the server cabinet structure. When the chassis 2 is assembled in place in the server cabinet structure, the operation status of the chassis 2 can be effectively judged, excluding the interference factor that the chassis 2 is not positioned properly, quickly positioning to the chassis 2 with operation problems, improving the assembly accuracy of the chassis 2 and the operation safety of the chassis 2. The assembled server cabinet structure has high reliability and meets the durability requirements.
