[0002] A server cabinet structure is a specialized cabinet used for AI computing, providing standardized mounting spaces and points for securely securing server equipment. Server equipment is stored within a chassis, which, to meet the ever-increasing computing power demands, requires frequent power module replacement. During the execution of analytical algorithms, servers may need to quickly replace faulty power systems in extreme environments. Therefore, the efficiency of chassis and cabinet assembly directly impacts the operational efficiency of server equipment.

[0003] Existing chassis rely on high-precision guides to position themselves within the cabinet. Typically, the chassis connects to the cabinet via pins. However, due to manufacturing tolerances, assembly errors, or long-term wear in high-precision guide designs, pin misalignment can occur, leading to pin deformation or poor contact. Existing chassis can also be connected to the cabinet using spring latches. However, due to the elastic fit between the spring latches and the cabinet, high-frequency vibrations can cause the spring latches to lose their locking force or fatigue, leading to loosening of the chassis and cabinet. Whether using pins or spring latches for positioning, the reliability of the chassis-to-cabinet assembly is insufficient, impacting the safe operation of server equipment. Summary of the Invention

[0027] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] Example 1

[0029] The present embodiment provides a server cabinet structure, including a cabinet 1 and a chassis 2. The cabinet 1 has a receiving cavity 11, and the receiving cavity 11 is used to store the chassis 2. Due to the insufficient vibration resistance of the traditional chassis 2 and cabinet 1, the reliability is reduced in long-term use and is prone to loosening. At the same time, the server cabinet structure lacks positioning status detection during assembly, and relies on manual judgment of whether the server cabinet structure is assembled in place. There is a risk of misjudgment, which increases the risk of 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, the present embodiment improves the server cabinet structure so that the server cabinet structure can still maintain good connection performance and operating status in a high-frequency vibration environment. The following is a detailed description.

[0030] like Figure 1-Figure 5 As shown, the inner wall of the accommodating cavity 11 is provided with a limiting portion 12 for guiding the arrangement direction of the chassis 2, and a positioning assembly 21 is provided on the chassis 2. The positioning assembly 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, and 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 realize the conversion of the rotational motion of the adjusting member 32 into the linear motion 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 accommodating cavity 11 through the positioning member 34.

[0031] The cabinet 1 may be a generally rectangular parallelepiped structure, with one end of the cabinet 1 along the width direction forming the opening of the accommodating cavity 11 and the other end forming the bottom of the accommodating cavity 11. Both ends of the cabinet 1 along the length direction are side walls. The opening of the accommodating cavity 11 may be located on a side wall of the cabinet 1. Accordingly, if the opening of the accommodating cavity 11 is arranged to face upward, the opening of the accommodating cavity 11 may be located on the top wall of the cabinet 1. The orientation of the opening of the accommodating cavity 11 may be selected based on the actual installation location of the cabinet 1.

[0032] The chassis 2 can be accurately loaded into the accommodating 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. The positioning member 34 moves in a direction perpendicular to the force 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 movement and displacement of the chassis 2. 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 durability of the server cabinet structure.

[0033] The positioning component 21 is arranged at the end of the chassis 2, which is convenient for operating the positioning component 21. The rotating adjustment member 32 can link the positioning member 34 to move. The transmission method of the positioning component 21 has good vibration resistance. The positioning member 34 is not easy to separate from the inner wall of the accommodating chamber 11. The positioning member 34 is connected to the inner wall of the accommodating chamber 11, which can also improve the convenience of operation. By rotating the adjustment member 32, the linear motion stroke of the positioning member 34 can be accurately controlled, which effectively reduces the complexity of the layout of the positioning component 21, avoids the driven stroke of the positioning member 34 being too long and occupying the space of the accommodating chamber 11, and realizes precise control of the operating stroke of the positioning member 34.

[0034] In one embodiment, the limiting portion 12 is disposed on the top wall and / or bottom wall of the accommodating cavity 11 , and the limiting portion 12 extends along the opening of the accommodating cavity 11 toward the bottom of the accommodating cavity 11 .

[0035] In other embodiments, the limiting portion 12 can also be set on the side wall of the accommodating cavity 11, and 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 bottom of the accommodating cavity 11.

[0036] 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 along the opening of the accommodating cavity 11 toward the cavity bottom of the accommodating cavity 11. The number of limiting portions 12 can be multiple, and multiple limiting portions 12 are arranged at equal intervals in the accommodating cavity 11 along the length direction of the cabinet 1. Each limiting portion 12 can be used to guide the chassis 2. The number of 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 is easy to install, and on the other hand, it is necessary to ensure that the air supply device 62 can effectively circulate air to the accommodating cavity 11, so as to achieve the effect of timely cooling the chassis 2.

[0037] In other embodiments, the limiting portion 12 can be a U-shaped structure, and the limiting portion 12 protrudes from the top wall and / or 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 of the U-shaped structure until the end of the chassis 2 is fully engaged 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.

[0038] In one embodiment, a sliding groove 13 is provided 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 provided on the chassis 2, and the sliding portion 22 is arranged corresponding to the sliding groove 13.

[0039] like Figure 2 、 Figure 5 As shown, since the limiting portion 12 is arranged on the top wall and / or bottom wall of the accommodating cavity 11, a sliding groove 13 is provided on the limiting portion 12, and the sliding groove 13 can also be located on the top wall and / or 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.

[0040] 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.

[0041] 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 facing away from the opening of the accommodating cavity 11.

[0042] 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 slot structure, one end of the slot structure being a closed end, and the other end of the slot structure being an open end, the open end being in communication with 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 slot structure, the structure of the limiting portion 12 is similar to that of the sliding slot 13, and it can be understood that the sliding slot 13 is provided inside the slot structure and is recessed relative to the slot structure; the sliding slot 13 is provided on the limiting portion 12, so that the chassis 2 cooperates with the sliding slot 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.

[0043] 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 .

[0044] For example, Figure 4 、 Figure 5 As shown, the positioning piece 34 is arranged at the top and bottom of the bracket seat 31, the matching portion 14 can be a hole position, the matching portion 14 is arranged on the limiting portion 12, and the positioning piece 34 is correspondingly plugged and fixed to the matching portion 14; when the chassis 2 is moved into position at the limiting portion 12, the positioning piece 34 is moved to the matching portion 14 by adjusting the positioning assembly 21; one end of the chassis 2 is abutted against the limiting portion 12, and the other end of the chassis 2 is connected to the matching portion 14 through the positioning piece 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 the length direction and the width direction of the cabinet 1 at the same time, ensuring the accuracy and stability of the installation of the chassis 2, so that the chassis 2 can cope with the high-frequency vibration environment without misalignment.

[0045] For example, a second sensor is provided in the mating portion 14 to detect whether the positioning member 34 is properly connected to the mating portion 14. When the positioning member 34 is properly connected to the mating portion 14, a second locking signal is triggered. This second locking signal can be used to determine the locking status of the positioning member 34, facilitating effective monitoring of the assembly of the chassis 2. If the positioning member 34 and the mating portion 14 cannot be locked, the problem can be promptly detected and the chassis 2 can be repaired.

[0046] In one embodiment, the adjusting member 32 and the positioning member 34 are both movably arranged through the bracket seat 31, the adjusting member 32 is located in the middle of the bracket seat 31, and an internal space for accommodating the linkage structure 33 is formed between the bracket seat 31 and the chassis 2. The positioning member 34 is located at the top and bottom of the bracket seat 31, and a positioning port 35 for guiding the positioning member 34 is provided on the bracket seat 31. The adjusting member 32 rotates relative to the bracket seat 31 to drive the linkage structure 33 to synchronously drive the relatively arranged positioning members 34 to move toward or in the opposite direction.

[0047] 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 toward or in opposite directions. The positioning member 34 moves into the limiting portion 12 and is positioned in the matching portion 14 to achieve locking. The positioning member 34 moves out of the limiting portion 12 to achieve unlocking. The rotational movement of the adjusting member 32 can be operated by automated equipment or manually.

[0048] For example, Figure 5 、 Figure 6As shown, the two positioning members 34 are symmetrically arranged relative to the position of the adjusting member 32. The adjusting member 32 can synchronously adjust the two positioning members 34 so that the two positioning members 34 can be synchronously moved the same distance, which is conducive to the synchronous positioning of the two positioning members 34 to the inner wall of the accommodating cavity 11, maintaining the stability of the connection between the chassis 2 and the inner wall of the accommodating cavity 11.

[0049] In one embodiment, the linkage structure 33 includes a connecting rod 41 and a movable rod 42 arranged 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.

[0050] 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, a first hinge groove is 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. The first hinge groove and the second hinge groove are both roughly U-shaped structures, and the two ends of the movable rod 42 are respectively axially connected to the first hinge groove and the second hinge groove. 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 the movable rod 42 from moving off due to lack of guidance, and effectively improving the movement accuracy of the positioning member 34.

[0051] In order to achieve the flexibility of the rotation of the movable rod 42, both ends of the movable rod 42 are arc structures, which reduces 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 achieve angle adjustment.

[0052] The positioning piece 34 is adapted to the positioning opening 35, and the positioning opening 35 is located above and below the connecting rod 41. When the connecting rod 41 moves along the width direction of the cabinet 1, in the process of the connecting rod 41 approaching the positioning opening 35, the connecting rod 41 drives the movable rod 42 to rotate at the hinge point. Since the positioning piece 34 is guided by the positioning opening 35, the positioning piece 34 is pushed out from the inner space of the bracket seat 31 to the outer space along the height direction of the cabinet 1, so that the two positioning pieces 34 are respectively locked with the top wall and bottom wall of the accommodating cavity 11; in the process of the connecting rod 41 moving away from the positioning opening 35, the connecting rod 41 drives the movable rod 42 to rotate at the hinge point, and the positioning piece 34 retracts from the outer space of the bracket seat 31 to the inner space along the height direction of the cabinet 1, so that the two positioning pieces 34 are respectively unlocked from the top wall and bottom wall of the accommodating cavity 11.

[0053] In one embodiment, part of the adjusting member 32 has threads, and the adjusting member 32 is threadedly connected to the bracket seat 31 ; the adjusting member 32 passes through the connecting rod 41 , and is provided with step portions 43 that movably abut against both sides of the connecting rod 41 .

[0054] For example, Figure 6 As shown, the portion of the adjusting member 32 that passes through the bracket seat 31 is threaded, and the bracket seat 31 is provided with a threaded hole 37 corresponding to the adjusting member 32. The portion of the adjusting member 32 that passes through the connecting rod 41 is a round rod structure. Rotation of the round rod structure does not affect the connecting rod 41. By rotating the adjusting member 32, it moves relative to the bracket seat 31 along the width direction of the cabinet 1, and the step portion 43 can then drive the connecting rod 41 to move along the width direction of the cabinet 1. The step portion 43 has a gap on both sides of the connecting rod 41, allowing the adjusting member 32 to move flexibly within the connecting rod 41, avoiding close contact between the step portion 43 and the connecting rod 41 and causing rotational interference with the connecting rod 41. The step portion 43 is equivalent to the shoulder of the connecting rod 41, and the step portion 43 is integrally formed with the connecting rod 41.

[0055] In order to facilitate the rotation of the adjustment member 32 relative to the bracket seat 31, a knob portion is provided at the end of the adjustment member 32 away from the chassis 2. The knob portion is conducive to rotation operation and accurately controls the movement stroke of the adjustment member 32 along the width direction of the cabinet 1.

[0056] A guide hole 38 for supporting the adjusting member 32 is provided on the chassis 2. The guide hole 38 and the threaded hole 37 are located in the same straight line direction. The adjusting member 32 extends into the guide hole 38 and rotates in the guide 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 guide hole 38 can be a round rod structure or have threads. The guide hole 38 is adapted to the adjusting member 32. The guide hole 38 effectively supports the adjusting member 32 so that it can move effectively in a straight line direction, and at the same time allows the adjusting member 32 to effectively support the connecting rod 41. The connecting rod 41 is suspended on the adjusting member 32 and does not rotate.

[0057] In one embodiment, the linkage structure 33 includes relatively spaced screws 44, and the positioning member 34 and the screws 44 form a kinematic pair through a threaded pair; a main bevel gear 45 is provided on the adjusting member 32, and a slave bevel gear 46 is provided at the opposite ends of the two screws 44 respectively. The main bevel gear 45 drives the slave bevel gear 46 to rotate, so that the rotational motion of the screw 44 is converted into linear motion of the positioning member 34.

[0058] like Figure 7As shown, the linkage structure 33 can be composed of various components, and its function is to convert the rotational motion of the adjustment member 32 into the linear motion of the positioning member 34. The two screws 44 are driven by the adjustment member 32 to achieve synchronous rotation. 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 opening 35, ensuring the stability of the kinematic pair formed by the positioning member 34 and the screws 44, and improving the movement accuracy of the positioning member 34. Similarly, the two positioning members 34 can achieve synchronous movement and are accurately positioned on the top and bottom walls of the accommodating chamber 11.

[0059] When the positioning member 34 and the screw 44 form a kinematic pair, the adjusting member 32 no longer needs to mate with the guide hole 38 in the chassis 2. A primary bevel gear 45 is provided at one end of the adjusting member 32, and the other end of the adjusting member 32 extends beyond the bracket seat 31. The portion of the adjusting member 32 that extends through the bracket seat 31 is a round rod structure, and the adjusting member 32 only achieves rotational motion, without horizontal movement. When the adjusting member 32 rotates, the primary bevel gear 45 rotates synchronously, which in turn drives the two secondary bevel gears 46 to rotate synchronously. The two secondary bevel gears 46 rotate relative to each other, allowing the two positioning members 34 to move synchronously and the same distance.

[0060] In one embodiment, the bracket base 31 and / or the chassis 2 is provided with a support member 47 for supporting the screw rod 44 , and the screw rod 44 is rotatably arranged relative to the support member 47 .

[0061] like Figure 7 As shown, in order to ensure the stability of the installation position of the screw 44, a plurality of support members 47 are provided at the end of the chassis 2. In this embodiment, the support members 47 are installed one-to-one with the screw 44, and a bearing is provided between the support members 47 and the screw 44. The rotational movement of the screw 44 does not affect the support members 47. The support members 47 effectively support the screw 44 and maintain the stability of the rotational movement of the screw 44.

[0062] In one embodiment, a hanging portion 36 is provided at the end of the positioning member 34 away from the linkage structure 33 . The hanging portion 36 is larger than the positioning opening 35 . The hanging portion 36 is located outside the bracket seat 31 .

[0063] For example, Figure 6 、 Figure 7As shown, the positioning member 34 can be a generally L-shaped structure, with the hook portion 36 located above and / or below the bracket seat 31. The positioning opening 35 can be a square through-hole. When the positioning member 34 retracts from the exterior space of the bracket seat 31 to the interior space, the hook portion 36 and the bracket seat 31 movably abut against each other to limit the positioning member 34, preventing the positioning member 34 from completely disengaging the positioning opening 35 and causing the positioning opening 35 to lose its guiding function. The size of the positioning member 34 is compatible with the size of the positioning opening 35, so that the positioning opening 35 can accurately guide the positioning member 34 in a straight line, preventing the positioning member 34 from deflecting when driven and failing to connect with the mating portion 14.

[0064] In one embodiment, the bottom of the accommodating cavity 11 is connected to one end of the chassis 2 facing the bottom of the accommodating cavity 11 via a self-locking structure 23 , and the self-locking structure 23 is configured to communicate with the liquid cooling system.

[0065] For example, Figure 4 、 Figure 5 As shown, a plug-in portion 51 is provided at the bottom of the accommodating cavity 11, and an inserting portion 52 is provided at one end of the chassis 2 facing the bottom of the accommodating cavity 11, and the plug-in portion 51 is correspondingly connected to the inserting portion 52; the plug-in portion 51 is configured to communicate with the liquid cooling system.

[0066] Specifically, the groups of plug-in portions 51 are arranged at equal intervals along the length of the cabinet 1. A group of plug-in portions 51 has two plug-in portions 51. One plug-in portion 51 can be the coolant inlet of the liquid cooling system and is located at the upper part of the bottom of the accommodating chamber 11; the other plug-in portion 51 can be the coolant outlet of the liquid cooling system and is located at the lower part of the bottom of the accommodating chamber 11. The number of groups of plug-in portions 51 corresponds to the number of chassis 2, and each group of plug-in portions 51 is connected to a corresponding chassis 2. Correspondingly, the end of the chassis 2 is provided with a plug-in portion 52. The groups of plug-in portions 52 are arranged at intervals on the chassis 2. The number of plug-in portions 52 in a group is two. A group of plug-in portions 52 is connected to a group of plug-in portions 51 in a one-to-one correspondence. Among them, one plug-in portion 52 can be the coolant inlet of the chassis 2, and the other plug-in portion 52 can be the coolant outlet of the chassis 2. When the plug-in portions 51 and the plug-in portions 52 are connected to each other, the liquid cooling system can effectively circulate the coolant in the chassis 2.

[0067] When chassis 2 is installed in cabinet 1, the end of chassis 2 abuts against stopper 12, and plug-in portion 51 and plug-in portion 52 connect in place, allowing coolant from the liquid cooling system to flow smoothly into chassis 2. A first sensor (not shown) is provided on self-locking structure 23. This first sensor is used to detect whether self-locking structure 23 is properly connected, thereby ensuring connectivity of the liquid cooling system. When self-locking structure 23 is properly connected, a first locking signal is triggered by the first sensor. This first locking signal is used to determine the connection status between chassis 2 and cabinet 1. If self-locking structure 23 is not properly connected, prompt repair and maintenance can be performed.

[0068] Among them, the first sensor and the second sensor are both electronic sensors, commonly used as micro switches. For example, when the self-locking structure 23 is connected, physical pressure is applied to the switch contacts to output an electrical signal, which can achieve a rapid response of the first sensor. 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 signal, which can achieve a non-physical contact response of the first sensor. It can also be an optical sensor, for example, an infrared transmitter 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, which can achieve a high-precision response of the first sensor. 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. The preset value is the pressure value of the self-locking structure 23 connected in place, which is used to determine that the self-locking structure 23 is connected in place. Similarly, the sensor types 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 examples are given here.

[0069] In one embodiment, the server cabinet structure also includes a heat dissipation portion 61 and an air blower 62. The heat dissipation portion 61 is arranged on the relative inner wall of the accommodating cavity 11. A heat dissipation duct 63 corresponding to the chassis 2 is formed on the heat dissipation portion 61. The air blower 62 is connected to the heat dissipation duct 63 so that convection wind is formed in the relative heat dissipation duct 63.

[0070] For example, Figure 4 As shown, the heat dissipation portion 61 is located on the inner wall at both ends along the length direction of the cabinet 1. The number of heat dissipation portions 61 can be multiple, one end of the heat dissipation portion 61 extends toward the opening of the accommodating cavity 11, and the other end of the heat dissipation portion 61 extends toward the bottom of the accommodating cavity 11; multiple heat dissipation portions 61 are arranged at intervals on the inner wall of the accommodating cavity 11, and heat dissipation ducts 63 are formed between adjacent heat dissipation portions 61. The heat dissipation ducts 63 correspond to the two ends of the chassis 2 along the width direction of the cabinet 1, and the airflow guided and discharged by the heat dissipation ducts 63 can form convection wind in the space corresponding to the opening and the space corresponding to the bottom of the accommodating cavity 11, thereby effectively cooling the accommodating cavity 11.

[0071] For example, the heat dissipation portion 61 may have a generally L-shaped structure, with the end of the heat dissipation portion 61 extending toward the bottom of the accommodating cavity 11, such that the heat dissipation portion 61 is closer to the self-locking structure 23 and the airflow discharged from the heat dissipation duct 63 is directly directed to the self-locking structure 23. Multiple heat dissipation portions 61 are arranged at equal intervals on the inner wall of the accommodating cavity 11. The length of the heat dissipation portion 61 is adapted to the width of the cabinet 1, and can cover a large area of ​​the side wall of the cabinet 1.

[0072] To facilitate assembly of the heat dissipation unit 61 and the blower 62 into the cabinet 1, the heat dissipation unit 61 is plugged into and positioned against the inner wall of the accommodating chamber 11. A heat dissipation slot 64 is provided on the inner wall of the accommodating chamber 11. The heat dissipation unit 61 is plugged into and secured to the heat dissipation slot 64, ensuring that a portion of the heat dissipation unit 61 is located within the heat dissipation slot 64 and the remaining portion of the heat dissipation unit 61 is located within the accommodating chamber 11. A window 65 is provided on the side wall of the cabinet 1. The window 65 is in communication with the accommodating chamber 11. Specifically, the window 65 is located on the opposite inner wall of the accommodating chamber 11. The blower 62 is installed within the window 65, abutting against the heat dissipation unit 61.

[0073] A filter 66 is provided on the window 65 and covers the air blower 62, allowing filtered air to enter the air blower 62, reducing the amount of impurities or contaminants that enter the accommodating chamber 11 and improving the safety of the operation of the chassis 2. The filter 66 can be provided with a multi-layer structure to achieve multi-effect air filtration, making the air entering the accommodating chamber 11 cleaner, preventing impurities or contaminants from adhering to the air blower 62, and thereby reducing the frequency of cleaning the air blower 62 and the accommodating chamber 11.

[0074] Exemplarily, a power interface (not shown in the figure) is provided at the end of the chassis 2 facing the bottom of the accommodating cavity 11, and accordingly, a power socket (not shown in the figure) is provided at the bottom of the accommodating cavity 11. The power interface is docked with the power socket to connect the chassis 2 with the power supply system.

[0075] Specifically, the air blower 62 may be a fan, which may be completely embedded in the window 65 . The air blower 62 is connected to the accommodating cavity 11 , so that the heat dissipation portion 61 can effectively guide the air.

[0076] In one embodiment, the server cabinet structure also includes a cover plate 7, which corresponds to the opening of the accommodating cavity 11. A docking assembly is provided between the cover plate 7 and the cabinet 1. The docking assembly 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 by 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 by the second docking structure 72.

[0077] For example, Figure 1-Figure 3As shown, the first docking structure 71 includes a first docking portion 81 and a first fixing portion 82, the first fixing portion 82 is elastically connected to the first docking portion 81, and a spring is arranged between the first fixing portion 82 and the first docking portion 81; a plurality of first docking structures 71 can be arranged on the top of the cover plate 7, specifically, the first docking portion 81 is arranged on both sides of the top of the cover plate 7, and circular holes are provided on both sides of the top of the cabinet 1, and the first fixing portion 82 is plugged into and matched with the circular hole; when the first fixing portion 82 is plugged into and positioned with the circular hole, the cover plate 7 can be elastically hung on the top of the cabinet 1.

[0078] Illustratively, the second docking structure 72 includes a second docking portion 83 and a second fixing portion 84. The second fixing portion 84 may be a square hole, and the second docking portion 83 and the second fixing portion 84 are plugged together. The side wall of the cover 7 may be provided with multiple second docking portions 83. When the second docking portions 83 and the second fixing portions 84 are plugged together, the cover 7 can be positioned on the side wall of the cabinet 1. The cover 7 can be quickly and accurately covered on the cabinet 1, is easy to disassemble, easy to maintain, and can effectively prevent dust.

[0079] 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. When assembling the cover plate 7, the first fixing portion 82 on the top of the cover plate 7 is inserted into the circular hole on the top of the cabinet 1. The first fixing portion 82 elastically cooperates with the circular hole to ensure that the first docking structure 71 is inserted into place; then the cover plate 7 is rotated to gradually approach the opening of the accommodating cavity 11, so that the second docking structure 72 is connected in place, and the second docking portion 83 is inserted into the second fixing portion 84. In order to improve the stability of the connection between the second docking portion 83 and the second fixing portion 84, the second docking portion 83 and the second fixing portion 84 can be connected by magnetic fixation to achieve convenience of connection.

[0080] Example 2

[0081] 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 using the server cabinet assembly method to achieve reliability of the server cabinet structure.

[0082] The cabinet 1 and the chassis 2 are connected through a self-locking structure 23. A first sensor is provided on the self-locking structure 23. The first sensor 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. When the self-locking structure 23 is connected into place, the first locking signal is triggered, and the first locking signal can be transmitted to the chassis operation control system.

[0083] A second sensor is provided on the mating part 14, which 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 abuts against the mating part 14, the second locking signal is triggered, and the second locking signal can be transmitted to the chassis operation control system.

[0084] The server cabinet assembly method specifically includes:

[0085] S1, chassis 2 is installed in cabinet 1;

[0086] The chassis 2 is installed into the cabinet 1 by 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 , thereby positioning the chassis 2 in the length direction of the cabinet 1 .

[0087] S2, one end of the chassis 2 is connected to the cabinet 1 through the self-locking structure 23, and a first locking signal is obtained;

[0088] The self-locking structure 23 includes a plug-in portion 51 and a plug-in portion 52. When the plug-in portion 51 and the plug-in portion 52 are connected in place, they can be mechanically locked automatically. It is understood that when the self-locking structure 23 is locked, the plug-in portion 51 and the plug-in portion 52 are tightly plugged in, which can effectively seal the transmission coolant of the liquid cooling system without the problem of coolant leakage in the self-locking structure 23.

[0089] When the end of the chassis 2 is in contact with the limit portion 12, the plug-in portion 51 is in contact with the plug-in portion 52, the first sensor triggers the first locking signal, and 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 not in place, and the installation position of the chassis 2 needs to be inspected.

[0090] S3, according to the first locking signal, the positioning member 34 is controlled to move in a direction perpendicular to the force direction of the self-locking structure 23, and the other end of the chassis 2 is connected to the matching portion 14 through the positioning member 34, and a second locking signal is obtained;

[0091] When 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 the positioning member 34 is controlled to be connected with 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, the second sensor triggers the second locking signal, and the chassis operation control system obtains the second locking signal.

[0092] The force 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 and height directions of the cabinet 1; if the second sensor cannot trigger the second locking signal, the positioning member 34 is not connected in place, and the installation position of the chassis 2 needs to be inspected.

[0093] Since there are a large number of chassis 2, and each chassis 2 is installed at a first sensor and a second sensor, once a positioning deviation occurs in the chassis 2, the chassis operation control system can accurately locate the chassis 2 with the positioning deviation problem based on the feedback from the first sensor and the second sensor. Furthermore, in the process of positioning at both ends of the chassis 2, any positioning deviation at either end of the chassis 2 can be monitored in a timely manner, which greatly improves the efficiency of assembling the chassis 2 and the efficiency of identifying that the chassis 2 is not installed in place.

[0094] S4, according to the second locking signal, the chassis 2 starts to operate, including operating the power supply system and the liquid cooling system;

[0095] 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 is started and operated only after it is assembled in the cabinet 1, thereby improving the safety of the normal operation of the chassis 2.

[0096] S5, judging whether the operating status of the chassis 2 is normal. If the operating status of the chassis 2 is normal, the cover 7 is closed on the side wall of the cabinet 1. If the operating status of the chassis 2 is abnormal, the chassis 2 is unlocked for maintenance.

[0097] The chassis operation control system determines whether the operating status of chassis 2 is normal. If the operating status of chassis 2 is normal, the power supply system can power on chassis 2 normally, and the liquid cooling system can supply coolant to chassis 2 normally, it means that chassis 2 does not need to be replaced or repaired temporarily, and the cover plate 7 is connected to the side wall of cabinet 1.

[0098] If chassis 2 operates abnormally, it means that there may be problems with the internal components of chassis 2. Excluding the factors of chassis 2 and cabinet 1 not being properly positioned, chassis 2 can be moved out of cabinet 1 for inspection.

[0099] 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 operating status of the chassis 2 can be effectively judged, interference factors that may cause the chassis 2 to be poorly positioned can be eliminated, and the chassis 2 with operating problems can be quickly located, thereby improving the accuracy of chassis 2 assembly and the safety of chassis 2 operation. The assembled server cabinet structure has high reliability and meets durability requirements.
