Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a server node and a server. Background Art

[0002] With the rise of big data, cloud computing, and artificial intelligence (AI), the computing requirements of data centers and servers are increasing. In order to handle complex logical operations and different data types, server nodes are usually integrated with different types of functional units. Multiple server nodes are integrated in the server cabinet.

[0003] In the related art, the chassis of the server node includes a first box and a second box. The volume of the second box is smaller than that of the first box. The first box and the second box can respectively place different types of functional units. When the functional unit placed in the second box is maintained, the first box and the second box need to be pulled out of the cabinet as a whole. The overall weight of the chassis is large, which is inconvenient to operate. Summary of the invention

[0004] The embodiment of the present application provides a server node and a server. The server node, through structural optimization, facilitates both the second box to be pulled out separately for maintenance and the first box and the second box to be pulled out as a whole relative to the cabinet for maintenance.

[0005] A first aspect of an embodiment of the present application provides a server node, which includes a first box body, a second box body and a first locking component; the first box body has a accommodating cavity, and the first box body includes an open first end; the second box body is located in the accommodating cavity, and the second box body can be inserted into the first box body from the first end or pulled out from the first box body from the first end; the first locking component is arranged between the side wall of the first box body and the side wall of the second box body, the first locking component is arranged close to the first end of the first box body, and the first locking component includes a linkage member, which can move back and forth to lock the first box body and the second box body, or release the lock between the first box body and the second box body.

[0006] By adopting the above scheme, the second box can be inserted into or pulled out from the first box from the first end of the first box, and the first box and the second box can be locked or unlocked by operating the first locking component; during daily maintenance, the first box and the second box can be locked by the first locking component, and the first box and the second box of the server node can be pulled out together for maintenance; the first locking component can be used to unlock the first box and the second box, and the second box can be pulled out alone for maintenance, which is easy to operate.

[0007] In practical applications, the server node includes a chassis, and the chassis includes a first box body and a second box body.

[0008] In one feasible solution, the server node includes a first functional unit and a second functional unit, the first functional unit is arranged in a first box, the second functional unit is arranged in a second box, and the first functional unit is electrically connected to the second functional unit.

[0009] Exemplarily, the first functional unit may include a central processing unit (CPU), a power module, a hard disk module, and the like.

[0010] Exemplarily, the second functional unit includes a graphics processing unit (GPU) and the like.

[0011] In a feasible solution, the first lock component also includes a toggle member, a first lock frame and a second lock frame; the first lock frame is fixedly arranged on the first box body, and the second lock frame is fixedly arranged on the outer side of the box side wall of the second box body; the toggle member is rotatably connected to the second box body, and the linkage member is connected to the toggle member; when the toggle member rotates, it can drive the linkage member to move to a first locking position or a first unlocking position. In the first locking position, the linkage member is simultaneously located in the second lock frame and the first lock frame, and in the first unlocking position, the linkage member is located outside the first lock frame. The structure of the first lock component is relatively simple and helps to reduce the occupied space. By rotating the toggle member of the first lock component, the linkage member can reciprocate between the first locking position and the first unlocking position to achieve locking and unlocking between the first box body and the second box body.

[0012] In some examples, a partition plate is fixedly installed in the first box body, and the partition plate divides the accommodating cavity of the first box body into a first cavity and a second cavity along the height direction of the server node. The second box body is located in the first cavity or the second cavity, and the first locking frame is set on the partition plate.

[0013] In one feasible solution, one of the linkage member and the toggle member is provided with an elongated hole, and the linkage member and the toggle member are connected by a connecting pin inserted in the elongated hole. This arrangement ensures that the linkage member can reciprocate along the direction of inserting into or leaving the first lock frame under the drive of the toggle member.

[0014] In one feasible solution, the middle part of the toggle member is rotatably connected to the second box, one end of the toggle member is connected to the linkage member, and the other end of the toggle member has a plug-in portion for cooperating with the tooling. This arrangement makes it convenient for the user to operate the toggle member, thereby switching the locked or unlocked state between the first box and the second box.

[0015] In one feasible solution, the server node is provided with first locking components at both ends along the first direction, and the two first locking components are arranged in linkage; the first direction is perpendicular to the plugging and unplugging direction of the second box relative to the first box. Such an arrangement is conducive to improving the locking force between the first box and the second box, and ensuring the reliable locking of the two.

[0016] In an achievable solution, the server node further includes a second lock component, which is mounted on the side wall of the first box and is disposed near the first end of the first box. The second lock component includes a lock rod, which is located inside the first box. The lock rod can rotate relative to the first box to lock the first box and the cabinet where the server node is installed, or release the lock between the first box and the cabinet. This arrangement can improve the stability and reliability of the installation of the server node in the cabinet; at the same time, when it is necessary to plug and unplug the second box separately, the first box and the cabinet can be locked to avoid misoperation of the first box and ensure the safety and reliability of plugging and unplugging the second box.

[0017] In a feasible solution, the first locking component and the second locking component are linked and configured such that: during the process of the first locking component locking the first box and the second box, force can be applied to the second locking component to release the lock between the first box and the cabinet.

[0018] In one feasible solution, the first lock component is linked with the second lock component, and is configured such that when the linkage component moves to the first locking position, an unlocking force can be applied to the first rod end of the lock rod component, so that the lock rod component moves in the direction of unlocking the first box body and the cabinet. This arrangement can simplify the operation process, and the first lock component and the second lock component can be compactly arranged, which is conducive to reducing the occupied space.

[0019] Specifically, the first lock component includes a linkage member that can lock or unlock the relative position of the first box and the second box, and the second lock component includes a lock rod member that can lock or unlock the relative position of the first box and the cabinet. When the linkage member moves in a direction that can lock the first box and the second box, the lock rod member can be rotated in a direction that unlocks the first box and the cabinet, thereby realizing linkage control between the first lock component and the second lock component.

[0020] In some examples, the locking rod comprises a first rod end and a second rod end opposite to each other, the first rod end is located in the accommodating cavity of the first box body, and the second rod end extends out of the first box body from the first end of the first box body. Such a configuration makes it convenient for users to operate the second locking component.

[0021] In one feasible solution, the locking rod is provided with a ratchet, and the first housing has a first through hole that matches the ratchet; the locking rod can rotate relative to the first housing to switch between a second locking position and a second unlocking position, in which at least part of the ratchet protrudes from the first through hole outside the first housing, and in the second unlocking position, the ratchet is located inside the first housing. The second locking component has a simple structure and is conducive to reducing the occupied space.

[0022] In one feasible solution, the second lock component further includes a mounting seat, the mounting seat is fixed to the inner side of the box side wall of the first box body, the lock rod is rotatably connected to the mounting seat, and the mounting seat has a second through hole, which is connected to the first through hole. In this way, the second lock component can be modularly arranged, which is convenient for maintenance and assembly.

[0023] In an achievable solution, the second locking component further includes a fixing member and an elastic member, the fixing member is fixed to the mounting seat, the locking rod is located between the fixing member and the mounting seat, one end of the elastic member abuts against the fixing member, and the other end of the elastic member abuts against the locking rod; the elastic member can keep the locking rod in the second locking position. This arrangement can ensure the locking effect of the first box body and the cabinet.

[0024] In one feasible solution, the server node is provided with a second locking component at both ends along the first direction, and the first direction is perpendicular to the plugging direction of the second box relative to the first box. Such a configuration is conducive to improving the locking effect between the first box of the server node and the cabinet where the server node is installed.

[0025] In one feasible solution, the server node further includes an auxiliary extraction component, which is installed at the end of the second box body close to the first end, and can rotate relative to the second box body, and is configured to generate a force that causes the second box body to move in an insertion direction of the first box body when rotating along a first rotation direction, and to generate a force that causes the second box body to move in an extraction direction of the first box body when rotating along a second rotation direction; the first rotation direction is opposite to the second rotation direction. In this way, the auxiliary extraction component cooperates with the first lock component to assist the overall plugging and unplugging operation of the first box body and the second box body, and also to assist the individual plugging and unplugging operation of the second box body, which is beneficial to reducing the occupation of the front space of the server node.

[0026] In one feasible solution, the extraction-assisting component includes a wrench, which is rotatably connected to the second box body, and the wrench includes a protruding arm; the first box body has a third through hole, and the protruding arm can extend from the third through hole and cooperate with the limit structure. In this way, the extraction-assisting component has a lever amplification effect and can meet the requirements of a larger insertion and extraction force.

[0027] Exemplarily, the protruding arm of the wrench may be provided with only one, or may be provided with more than two. When the protruding arm of the wrench is provided with more than two, each protruding arm of the wrench may cooperate with the limiting structure in sequence.

[0028] Exemplarily, the limiting structure is disposed on a cabinet wall of a cabinet in which the server node is installed; or, the first box of the server node is detachably connected to the limiting fixture, and the limiting structure is disposed on the limiting fixture.

[0029] A second aspect of an embodiment of the present application provides a server, which includes a cabinet and a server node installed in the cabinet, and the server node adopts the server node described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] Servers are widely used in Internet service providers, enterprise platforms, research institutions and other scenarios for storage, computing and networking needs. With the rapid development of the information and communication technology industry, the application of servers has expanded to the fields of cloud computing and artificial intelligence (AI), and the demand for computing resources to process and analyze large amounts of data is growing.

[0051] A server may include one or more server nodes, and multiple server nodes are set in the server cabinet. To meet the growing computing power requirements of servers, different types of functional units may be integrated into a server node. Figure 1 , Figure 1 This is a schematic diagram of the structure of the server in the embodiment of the present application.

[0052] like Figure 1 As shown, the server 1 includes a cabinet 2 and multiple server nodes 3, and the multiple server nodes 3 are sequentially inserted into the cabinet 2. The server nodes 3 can be cooled by air cooling or liquid cooling. A side wall (usually the back side mentioned later) of the server node 3 is provided with multiple plug connectors to be plugged and matched with multiple plug connectors of the cabinet 2 to realize power supply, signal transmission or circulation of cooling medium, etc.

[0053] When different types of functional units are integrated in the server node 3, the chassis of the server node 3 can adopt a nested structure. Figure 2 , Figure 2 It is a schematic diagram of the structure of the server node of the server in the embodiment of the present application.

[0054] like Figure 2 As shown, the server node 3 includes a chassis 100, and the chassis 100 includes a first box body 10 and a second box body 20, and the second box body 20 is located in the accommodating cavity 10a of the first box body 10. That is, the second box body 20 is nested in the first box body 10. The accommodating cavity 10a of the first box body 10 is divided into two parts, one part is the space occupied by the second box body 20, and the rest is the space not occupied by the second box body 20. Some types of functional units can be installed in the space of the accommodating cavity 10a of the first box body 10 not occupied by the second box body 20, and other types of functional units can be installed in the second box body 20.

[0055] For simplicity, Figure 2 It is shown in the figure that a first functional unit 71 is installed in the first box 10, and a second functional unit 72 is installed in the second box 20, and the first functional unit 71 is electrically connected to the second functional unit 72. In this way, the length of the communication cable between the first functional unit 71 and the second functional unit 72 can be shortened, which is conducive to improving the communication rate. The positional relationship in the figure is only an example, and the relative positional relationship between the first functional unit 71 and the second functional unit 72 can be set according to actual conditions. In some examples, the first functional unit 71 is electrically connected to the first connector 711, and the second functional unit 72 is electrically connected to the second connector 721. The first connector 711 and the second connector 721 are plugged in to achieve communication or power supply, etc.

[0056] In actual applications, the server node 3 needs to be inserted into or removed from the cabinet 2 as a whole, and the second box 20 of the server node 3 also needs to be inserted into or removed from the first box 10 separately.

[0057] Taking the server node 3 integrated with a CPU (central processing unit) and a GPU (graphics processing unit) as an example, the GPU is installed in the second box 20, and the CPU, memory, hard disk module, and power module are installed in the space of the first box 10 not occupied by the second box 20. That is, the first functional unit 71 includes the CPU, memory, hard disk module, power module, etc., and the second functional unit 72 includes the GPU. In order to meet the installation requirements of the CPU and GPU, etc., the height of the first box 10 can be 4U, and the height of the second box 20 can be 3U. Here, 1U is 1 unit, and 1U=44.45mm. In other application examples, the first box 10 and the second box 20 can also have other height dimensions.

[0058] In practical applications, the CPU, memory, hard disk module, power module, etc. installed in the first box body 10 can be located above the second box body 20 or below the second box body 20 .

[0059] In an application example, the overall weight of the server node 3 integrated with the CPU and GPU can reach about 80 kilograms, wherein the overall weight of the second box 20 and the functional units installed therein can reach about 50 kilograms. Thus, when the server node 3 is plugged in and out as a whole or the second box 20 and the functional units installed therein are plugged in and out separately, a relatively large plugging and unplugging force is required.

[0060] The embodiment of the present application optimizes the structure of the chassis 100 of the server node 3. By integrating auxiliary plug-in accessories on the chassis 100, it is convenient for the plug-in and pull-out of the server node 3 as a whole, and for the plug-in and pull-out of the second box 20, while avoiding excessive occupation of the front space of the chassis 100. Here, the front of the chassis 100 refers to the side of the chassis 100 that faces the outside of the cabinet 2 or the user after the server node 3 is placed in the cabinet 2 of the server 1; correspondingly, the side of the chassis 100 opposite to the front is the back, which is the side of the chassis 100 that faces the inside of the cabinet 2 or the back of the user after the server node 3 is placed in the cabinet 2. Figure 1 and Figure 2 As indicated in the figure, the front side of the chassis 100 faces the negative Y direction, and the back side faces the positive Y direction.

[0061] Please refer to Figure 3 and Figure 4 , Figure 3 and Figure 4 All of them are structural schematic diagrams of the chassis provided in the embodiments of the present application, wherein: Figure 4 It is a partial structural diagram in which the second box body 20 has not yet been completely inserted into the first box body 10.

[0062] For the convenience of description, three directions are defined in this article, namely, a first direction X, a second direction Y and a third direction Z. In combination with the structure shown in the figure, the first direction X is the width direction of the server node 3 or the chassis 100, the second direction Y is the length direction (also called the depth direction) of the server node 3 or the chassis 100, and the third direction Z is the height direction of the server node 3 or the chassis 100. Figure 1 In the server 1 shown, the first direction X, the second direction Y and the third direction Z are also respectively the width direction, the length (depth) direction and the height direction of the server 1 , and the plurality of server nodes 3 are stacked in the height direction of the server 1 .

[0063] like Figure 1 As shown, the server node 3 is inserted into the cabinet 2 of the server 1 along the second direction Y. Figure 4 As shown, in the chassis 100 of the server node 3, the second box body 20 is inserted into the first box body 10 along the second direction Y.

[0064] In this embodiment, the chassis 100 of the server node 3 includes a first box body 10 , a second box body 20 , and a first locking component 40 .

[0065] The first box body 10 has a receiving cavity 10a. The first box body 10 includes a first end 101 and a second end 102 opposite to each other in the second direction Y.

[0066] The second box body 20 is located in the accommodating cavity 10 a of the first box body 10 , and the second box body 20 includes a third end 201 and a fourth end 202 opposite to each other in the second direction Y.

[0067] When the second box 20 is inserted into the first box 10 , the third end 201 of the second box 20 is adjacent to the first end 101 of the first box 10 , and the fourth end 202 of the second box 20 is adjacent to the second end 102 of the first box 10 .

[0068] The chassis 100 can be inserted into the cabinet 2 from the first end 101 to the second end 102. It can be understood that the first end 101 of the first box body 10 is the front end of the chassis 100, and the second end 102 of the first box body 10 is the back end of the chassis 100.

[0069] In the illustrated example, the insertion direction of the second box body 20 relative to the first box body 10 is from the first end 101 to the second end 102, or from the third end 201 to the fourth end 202; the removal direction of the second box body 20 relative to the first box body 10 is from the second end 102 to the first end 101, or from the fourth end 202 to the third end 201. In other words, the insertion and removal direction of the second box body 20 relative to the first box body 10 is the second direction Y.

[0070] The first lock component 40 is disposed between the first box body 10 and the second box body 20, and is configured to lock the first box body 10 and the second box body 20, or to release the lock between the first box body 10 and the second box body 20. The first lock component 40 has a first locking position for locking the first box body 10 and the second box body 20, and a first unlocking position for releasing the lock between the first box body 10 and the second box body 20.

[0071] After the above arrangement, the first box body 10 and the second box body 20 of the chassis 100 can be connected as a whole or separated by the operation of the first locking component 40, so as to achieve locking or unlocking between the two; during daily maintenance, the first locking component 40 is used to lock the first box body 10 and the second box body 20, and the first box body 10 and the second box body 20 can be pulled out together for maintenance; the first locking component 40 is used to unlock the first box body 10 and the second box body 20, and the second box body 20 can be pulled out alone for maintenance, which is easy to operate.

[0072] In this embodiment, the chassis 100 of the server node 3 further includes an auxiliary extraction component 30, which is rotatably connected to the second box body 20. The auxiliary extraction component 30 is configured to generate a force that causes the second box body 20 to move along the insertion direction of the first box body 10 when rotating along the first rotation direction, and to generate a force that causes the second box body 20 to move along the extraction direction of the first box body 10 when rotating along the second rotation direction; the first rotation direction is opposite to the second rotation direction. In this way, combined with the first lock component 40, the auxiliary extraction component 30 can provide a force for the individual insertion and extraction of the second box body 20, and can also provide a force for the overall insertion and extraction of the first box body 10 and the second box body 20, avoiding the need to set auxiliary extraction structures on both the first box body 10 and the second box body 20, which is conducive to reducing the occupation of the front space of the chassis 100.

[0073] Using the above solution, the plugging and unplugging operation of the second box 20 relative to the first box 10 is as follows:

[0074] When the second box 20 is inserted into the first box 10, the extraction-assisting component 30 installed on the second box 20 can be used to rotate the extraction-assisting component 30 along the first rotation direction to generate a force acting on the second box 20 along the insertion direction, so as to facilitate the insertion of the second box 20 into the first box 10. After the second box 20 is inserted into the first box 10, the first box 10 and the second box 20 can be locked by the first locking component 40 to limit the relative position of the first box 10 and the second box 20.

[0075] When the second box body 20 is pulled out of the first box body 10, the lock between the first box body 10 and the second box body 20 is first released by the first locking component 40, and the auxiliary pulling component 30 installed on the second box body 20 can be used to rotate the auxiliary pulling component 30 along the second rotation direction to generate a force acting on the second box body 20 along the pulling direction, so as to facilitate the second box body 20 to be pulled out of the first box body 10.

[0076] Using the above solution, the plugging and unplugging operation of the chassis 100 relative to the cabinet 2 of the server 1 is as follows:

[0077] When the chassis 100 is operated as a whole, the first box body 10 and the second box body 20 can be locked by the first locking component 40 to limit the relative position of the two.

[0078] When the case 100 is inserted into the cabinet 2, the extraction-assisting component 30 installed on the second case 20 can be used to rotate the extraction-assisting component 30 along the first rotation direction to generate a force acting on the second case 20 along the insertion direction. Since the second case 20 and the first case 10 are locked, the force generated by the extraction-assisting component 30 actually acts on the first case 10 and the second case 20, making it easier for the case 100 to be inserted into the cabinet 2.

[0079] When the case 100 is pulled out of the cabinet 2, the pull-out assisting component 30 installed on the second case 20 can be used to rotate the pull-out assisting component 30 along the second rotation direction to generate a force acting on the second case 20 along the pull-out direction. Since the second case 20 and the first case 10 are locked, the force generated by the pull-out assisting component 30 actually acts on the first case 10 and the second case 20, making it easier for the case 100 to be pulled out of the cabinet 2.

[0080] The chassis 100 provided in this embodiment only needs to set an auxiliary extraction component 30 on the second box body 20, and cooperate with the first locking component 40 between the second box body 20 and the first box body 10, so as to facilitate the plugging and unplugging operations of the second box body 20 and the chassis 100 as a whole, which is beneficial to reducing the occupation of the front space of the chassis 100.

[0081] In a specific implementation, the outer contour size of the second box body 20 is smaller than that of the first box body 10 , so that the second box body 20 can be located inside the first box body 10 .

[0082] Some examples include Figure 2 As shown, the length of the second box body 20 can be set smaller than the length of the first box body 10. After the second box body 20 is inserted into the first box body 10, there is still space between the fourth end 202 of the second box body 20 and the second end 102 of the first box body 10. This space is part of the accommodating cavity 10a and can be used to install functional units such as power modules.

[0083] The first box body 10 may include a first box top wall 110, a first box bottom wall 120, a first box side wall 130, and a second box side wall 140. The first box top wall 110 and the first box bottom wall 120 are arranged opposite to each other in the third direction Z, and the first box side wall 130 and the second box side wall 140 are arranged opposite to each other in the first direction X. The first end 101 of the first box body 10 is an open end or an exposed end, and the second box body 20 can be inserted into the first box body 10 from the first end 101 or pulled out from the first box body 10 from the first end 101.

[0084] The second box body 20 may include a second box top wall 210, a second box bottom wall 220, a third box side wall 230, a fourth box side wall 240 and a fifth box side wall 250. The second box top wall 210 and the second box bottom wall 220 are arranged opposite to each other in the third direction Z, the third box side wall 230 and the fourth box side wall 240 are arranged opposite to each other in the first direction X, and the fifth box side wall 250 is located at the third end 201 of the second box body 20.

[0085] The first box side wall 130 of the first box body 10 and the third box side wall 230 of the second box body 20 are located at the same end, and the second box side wall 140 of the first box body 10 and the fourth box side wall 240 of the second box body 20 are located at the same end.

[0086] In other embodiments, the structures of the first box body 10 and the second box body 20 may also be in other forms, not limited to the above. For example, the second box body 20 may not be provided with the second box top wall 210 .

[0087] In a specific implementation, the extraction-assisting component 30 is installed at the third end 201 of the second box body 20 , that is, close to the front side of the chassis 100 , so as to facilitate the operation of the extraction-assisting component 30 .

[0088] The extraction-assisting component 30 may be disposed close to the third box side wall 230 and / or the fourth box side wall 240 to reduce the occupation of the front space of the chassis 100 .

[0089] In some examples, extraction-assisting components 30 are provided at both ends of the second box body 20 along the first direction X, so as to balance the forces applied to the second box body 20 or the locked first box body 10 and the second box body 20 .

[0090] In a specific implementation, the first lock component 40 is installed near the front side of the chassis 100, which is convenient for operating the first lock component 40. The first lock component 40 is arranged between the side wall of the first box body 10 and the side wall of the second box body 20, and the first lock component 40 is arranged near the first end 101 of the first box body 10.

[0091] by Figure 3 and Figure 4As shown, the first lock component 40 can be arranged between the first box side wall 130 of the first box body 10 and the third box side wall 230 of the second box body 20, and / or, the first lock component 40 can be arranged between the second box side wall 140 of the first box body 10 and the fourth box side wall 240 of the second box body 20.

[0092] In some examples, first locking components 40 are disposed at both ends of the chassis 100 along the first direction X, so that the locking force between the first box body 10 and the second box body 20 is balanced.

[0093] In this embodiment, the chassis 100 further includes a second lock component 50, which is mounted on the first box body 10, and is configured to lock the first box body 10 and the cabinet 2, or to release the lock between the first box body 10 and the cabinet 2. In other words, the second lock component 50 has a second locking position for locking the first box body 10 and the cabinet 2, and a second unlocking position for releasing the lock between the first box body 10 and the cabinet 2.

[0094] After the configuration is made in this way, after the chassis 100 is installed in the cabinet 2 of the server 1, the first box 10 and the cabinet 2 can be locked by the second lock component 50 to limit the relative position of the first box 10 and the cabinet 2. In combination with the locking of the first box 10 and the second box 20 by the first lock component 40, the stability and reliability of the chassis 100 installed in the cabinet 2 can be improved; at the same time, when the second box 20 needs to be plugged in or out separately, the first box 10 and the cabinet 2 are locked by the second lock component 50, which can ensure the safety and reliability of the plugging and unplugging operation of the second box 20.

[0095] In a specific implementation, the second locking component 50 is installed at the first end 101 of the first box body 10 , that is, close to the front side of the chassis 100 , so as to facilitate the operation of the second locking component 50 .

[0096] The second locking component 50 may be disposed close to the first box side wall 130 or the second box side wall 140 to reduce the occupation of the front space of the chassis 100 .

[0097] In some examples, a second locking member 50 is provided at both ends of the first box 10 along the first direction X, so that the locking force between the first box 10 and the cabinet 2 is balanced. The second locking member 50 can be installed on the side wall of the first box 10 to Figure 3 and Figure 4 As shown, the second lock component 50 is mounted on the first box side wall 130 , and / or the second lock component 50 is mounted on the second box side wall 140 .

[0098] Figure 3 and Figure 4In the example shown, the second box body 20 is provided with a first locking component 40 at both ends in the first direction X, and the first box body 10 is provided with a second locking component 50 at both ends in the first direction X. In the figure, the first locking component 40 near the third box side wall 230 is in the first unlocked position, the first locking component 40 near the fourth box side wall 240 is in the first locked position, the second locking component 50 near the first box side wall 130 is in the second locked position, and the second locking component 50 near the second box side wall 140 is in the second unlocked position.

[0099] The specific structure of the first locking component 40 is introduced below.

[0100] Please refer to Figures 5 to 8 , Figure 5 This is a partial enlarged view of the position of the first locking component on the side where the second case side wall of the case is located in the embodiment of the present application. Figure 6 This is a partial enlarged view of the second box body at the position of the first locking component on the side where the fourth box side wall is located in the embodiment of the present application. Figure 7 This is a partial enlarged view of the second box body at the position of the first locking component on the side where the third box side wall is located in the embodiment of the present application. Figure 8 for Figure 7 The exploded view of the first lock component is shown in FIG. To clearly illustrate the structure of the first lock component, Figure 5 Only the structure of the first lock component 40 and the first box body 10 and the second box body 20 is shown. Figures 6 to 8 Only the structures of the first lock component 40 and the second box body 20 are shown. Figure 5 and Figure 6 The first locking member 40 is in the first locking position, Figure 7 and Figure 8 The first locking component 40 is in the first unlocking position.

[0101] In this embodiment, the first locking component 40 includes a linkage member 42 , and the linkage member 42 can reciprocate to lock the first box body 10 and the second box body 20 , or release the lock between the first box body 10 and the second box body 20 .

[0102] In a specific implementation, the first locking component 40 further includes a toggle member 41 , a first locking frame 43 and a second locking frame 44 .

[0103] The first locking frame 43 is fixedly mounted on the first box body 10. In some examples, the first locking frame 43 can be an integrally formed structure with the first box body 10. In other examples, the first locking frame 43 can also be formed separately and then fixedly connected to the first box body 10.

[0104] The second lock frame 44 is fixedly mounted on the outer side of the box side wall of the second box body 20. In some examples, the second lock frame 44 can be an integrally formed structure with the second box body 20. In other examples, the second lock frame 44 can also be formed separately and then fixedly connected to the second box body 20.

[0105] The toggle member 41 is rotatably connected to the second housing 20, and the linkage member 42 is connected to the toggle member 41. When the toggle member 41 rotates, it can drive the linkage member 42 to move to a first locking position located in both the second lock frame 44 and the first lock frame 43, or it can drive the linkage member 42 to move to a first unlocking position located outside the first lock frame 43. The first lock frame 43 and the second lock frame 44 are arranged in the moving direction of the linkage member 42.

[0106] In some examples, the moving direction of the linkage member 42 is a linear direction, specifically, it can be set to be along the third direction Z, the first lock frame 43 and the second lock frame 44 are arranged in the third direction Z, and the first lock frame 43 is located above the second lock frame 44. This arrangement is conducive to reducing the occupied space of the first lock component 40, and is also convenient for the arrangement of the first lock frame 43 and the second lock frame 44.

[0107] In a specific implementation, at the first unlocking position, part of the linkage member 42 is inserted into the second lock frame 44. In this way, the linkage member 42 can be limited.

[0108] In a specific implementation, at least one of the toggle member 41 and the linkage member 42 is provided with an elongated hole 422, and the linkage member 42 and the toggle member 41 are connected by a connecting pin 46 inserted into the elongated hole 422. In this way, it can be ensured that the linkage member 42 can reciprocate along the direction in which it can be inserted into or separated from the first lock frame 43 under the drive of the toggle member 41, and the relevant arrangement of the elongated hole 422 can ensure that the moving direction of the linkage member 42 is a linear direction.

[0109] The toggle member 41 is rotatably connected to the third box side wall 230 or the fourth box side wall 240 of the second box body 20, and the rotation center line of the toggle member 41 is parallel to the first direction X, so that the rotation of the toggle member 41 can drive the linkage member 42 to move in the third direction Z.

[0110] like Figure 5 As shown, taking the first lock component 40 installed on the fourth box side wall 240 of the second box body 20 as an example, the second box body 20 is located behind the first box body 10, and the first lock component 40 is located in the space formed between the fourth box side wall 240 of the second box body 20 and the second box side wall 140 of the first box body 10.

[0111] For the first locking component 40 installed on the third box side wall 230 of the second box body 20 , the first locking component 40 is located in a space formed between the third box side wall 230 of the second box body 20 and the first box side wall 130 of the first box body 10 .

[0112] The toggle member 41 may be in a strip or rod-shaped structure, the middle portion of the toggle rod 41 is rotatably connected to the second housing 20, one end of the toggle member 41 is connected to the linkage member 42, and the other end of the toggle member 41 has a plug-in portion 412 for cooperating with a tool. In practical applications, the tool can be plugged into the plug-in portion 412 of the toggle member 41 to apply force to the toggle member 41, causing it to rotate and drive the linkage member 42 to move.

[0113] In actual configuration, one end of the toggle member 41 provided with the plug-in portion 412 is close to the third end 201 of the second housing 20, and the end of the toggle member 41 connected to the linkage member 42 is relatively far from the third end 201 of the second housing 20. In this way, after assembly, the plug-in portion 412 of the toggle member 41 is close to the front side of the chassis 100, which facilitates the application of force to the toggle member 41.

[0114] Meanwhile, the end of the toggle member 41 provided with the plug portion 412 does not extend out of the third end 201 of the second housing 20. After assembly, the first locking component 40 occupies the dimension of the chassis 100 in the second direction Y.

[0115] Exemplarily, the plug-in portion 412 of the toggle member 41 may be in the form of a socket or a notch.

[0116] like Figure 8 As shown, one end of the toggle member 41 connected to the linkage member 42 has a first connection hole 411, and one end of the linkage member 42 connected to the toggle member 41 has a second connection hole 422. The connection pin 46 passes through the first connection hole 411 and the second connection hole 422 to connect the linkage member 42 to the toggle member 41. The second connection hole 422 is a long hole, and the length direction of the long hole extends along the second direction Y. When force is applied to the toggle member 41 to rotate it, the movement of the connection pin 46 in the long hole limits the rotation of the linkage member 42 and causes the linkage member 42 to move along the third direction Z.

[0117] In other embodiments, the first connection hole 411 of the shifting member 41 may also be configured as a long hole.

[0118] like Figure 8 As shown, taking the first lock component 40 installed on the third box side wall 230 of the second box body 20 as an example, a boss 260 can be set on the third box side wall 230, and the first lock component 40 includes a first rotating shaft 45, which passes through the toggle member 41 and is inserted into the boss 260, so that the toggle member 41 can rotate around the first rotating shaft 45.

[0119] like Figure 7 and Figure 8As shown, the first lock component 40 is in the first unlocking position, and the toggle member 41 is in a position extending substantially along the second direction Y. At this time, the linkage member 42 is inserted into the second lock frame 44, and the linkage member 42 can partially extend out of the second lock frame 44, but the extended portion has no matching relationship with the first lock frame 43. When it is necessary to lock the first box body 10 and the second box body 20, a force can be applied to the end where the plug-in portion 412 of the toggle member 41 is located through a tool, so that the end where the plug-in portion 412 of the toggle member 41 is located rotates downward, so that the end of the toggle member 41 connected to the linkage member 42 rotates upward, driving the linkage member 42 to move upward, so that the linkage member 42 can be inserted into the first lock frame 43 to be in the first locking position, as shown in FIG. Figure 5 and Figure 6 shown.

[0120] In a specific implementation, the first locking component 40 may be provided with a stop structure for limiting the position of the toggle member 41 or the linkage member 42 so that the linkage member 42 can be maintained at the first locking position or the first unlocking position.

[0121] In some examples, the stop structure may be a damping structure or a fixed-point limiting mechanism, and the damping structure is disposed between the toggle member 41 and the first rotating shaft 45, so that the toggle member 41 can be maintained in the first unlocking position, or can be maintained in the first locking position. The damping structure or the fixed-point limiting mechanism can be provided by those skilled in the art based on conventional technology, and will not be described in detail here.

[0122] In some other examples, the stop structure may include a first limit portion and a second limit portion, wherein the first limit portion is used to keep the toggle member 41 in the first unlocked position, and the second limit portion is used to keep the linkage member 42 in the first locked position. The first limit portion may be a stopper located below the toggle member 41, and the stopper may be fixed to the side wall of the second box body 20. When the toggle member 41 rotates to the first unlocked position, it is restricted by the baffle and cannot continue to rotate. Figure 7 The second limiter can be a floating spring structure disposed between the second lock frame 44 and the linkage member 42. After the linkage member 42 moves to the first locking position, the floating spring structure can apply force to the linkage member 42 to keep it in the first locking position. The setting of the floating spring structure can be realized by those skilled in the art based on conventional technology, which will not be described in detail here.

[0123] To facilitate the installation of the first locking frame 43 in the first box body 10, a partition may be provided in the accommodating cavity 10a of the first box body 10. Fig. 9 , Fig. 9 A partial enlarged view of the first box body near the first end side is shown.

[0124] like Fig. 9As shown, the partitions provided in the first box body 10 include a partition plate 150, which is arranged in parallel with the first box top wall 110 and the first box bottom wall 120, and is located between the first box top wall 110 and the first box bottom wall 120, and divides the accommodating chamber 10a of the first box body 10 into a first chamber 11a and a second chamber 12a in the third direction Z, and the first chamber 11a is located below the second chamber 12a. The second box body 20 is located in the first chamber 11a. The height of the first chamber 11a in the third direction Z matches the height dimension of the second box body 20.

[0125] The two sides of the partition plate 150 in the first direction X are connected to the first box side wall 130 and the second box side wall 140 respectively. Figure 5 and Fig. 9 The first locking frame 43 can be fixed on the partition plate 150. The first locking frame 43 and the second locking frame 44 both have through holes for the linkage member 42 to be inserted into. The first locking frame 43 and the second locking frame 44 correspond in position in the third direction Z, that is, the through hole of the first locking frame 43 is connected to the through hole of the second locking frame 44.

[0126] In addition to facilitating the installation of the first locking frame 43 , the partition plate 150 can also provide an installation base for the functional unit installed in the second cavity 12 a of the first housing 10 . Exemplarily, the hard disk module installed in the first housing 10 can be supported by the partition plate 150 .

[0127] The partitions provided in the first box body 10 may further include a side partition 160, which is arranged in parallel with the first box side wall 130 or the second box side wall 140, and is located in the second cavity 12a, and the top side edge of the side partition 160 is connected to the partition plate 150, and the bottom side edge is connected to the first box bottom wall 120. Two side partitions 160 may be provided, one side partition 160 is provided close to the first box side wall 130, and the other side partition 160 is provided close to the second box side wall 140. The provision of the two side partitions 160 does not affect the nesting cooperation between the second box body 20 and the first box body 10. After the second box body 20 is inserted into the first box body 10, the two side partitions 160 are respectively located on the outside of the third box side wall 230 and the fourth box side wall 240 of the second box body 20. In other words, a space for accommodating the second box body 20 is defined between the two side partitions 160 , the partition plate 150 and the first box bottom wall 120 , and the side partitions 160 are equivalent to a further division of the first cavity 11 a .

[0128] With such arrangement, the second box 20 can be separated from the functional units installed in the first box 10 , thereby preventing the functional units in the first box 10 from being interfered with when the second box 20 is plugged in or out of the first box 10 .

[0129] Fig. 9The first box body 10 in the figure can only show the side partition plate 160 close to the first box side wall 130 due to the viewing angle.

[0130] In a specific implementation, the dimension of the side partition 160 in the second direction Y is smaller than the length of the first box side wall 130 or the second box partition wall 140. On the side where the first end 201 of the first box body 10 is located, there is an avoidance distance between the end of the side partition 160 and the end of the first box side wall 130 or the end of the second box side wall 140. The avoidance distance is used to avoid the first lock component 40 so that the second box body 20 is located behind the first box body 10, and the linkage 42 of the first lock component 40 can cooperate with the first lock frame 43.

[0131] In other embodiments, the partition plate 150 or the side partition plate 160 may not be provided in the first box body 10, and the first locking frame 43 may be fixed on the inner side of the first box side wall 130 or the second box side wall 140; the second box top wall 210 of the second box body 20 may be used as an installation base for functional units such as a hard disk module.

[0132] In some embodiments, when the chassis 100 is provided with first locking components 40 at both ends of the first direction, the two first locking components 40 may also be provided in linkage. For example, the two toggle members 41 may be connected by a linkage rod, so that when one toggle member 41 is operated, the other toggle member 41 moves accordingly.

[0133] The specific structure of the second locking component 50 is introduced below.

[0134] Please refer to Figures 10 to 16 , Fig.10 This is a partial enlarged view of the first box body at the position of the second lock component on the side where the first box side wall is located in the embodiment of the present application. Fig.11 and Fig.12 The schematic diagrams of the structure of the second lock component at two viewing angles are shown respectively, Fig.13 and Fig.14 The exploded schematic diagrams of the second lock component from two perspectives are shown respectively, Fig.15 A partial cross-sectional view of the first box body at the position of the second lock component on the side where the first box side wall is located is shown, Fig.16 A partial cross-sectional view of the first box body at the position of the second locking component on the side where the second box side wall is located is shown. Fig.10 , Fig.11 and Fig.15 The second locking member 50 is in the second locking position, Fig.16 The second locking component 50 is in the second unlocking position.

[0135] In this embodiment, the first box side wall 130 and the second box side wall 140 of the first box body 10 are both installed with the second locking component 50 .

[0136] The second locking component 50 includes a locking rod 51, which is located on the inner side of the first box 10. The locking rod 51 can rotate relative to the first box 10 to lock the first box 10 and the cabinet 2 where the server node 1 is installed, or release the lock between the first box 10 and the cabinet 2.

[0137] In a specific implementation, a ratchet 511 is provided on the locking rod 51 , and the first box body 11 has a first through hole 171 matched with the ratchet 511 .

[0138] The first box side wall 130 and the second box side wall 140 of the first box body 11 are both provided with first through holes 171 , which are respectively matched with the locking rods 51 of the two second locking components 50 .

[0139] The locking rod 51 can rotate relative to the first box body 10 to switch between a second locking position and a second unlocking position. In the second locking position, at least a portion of the ratchet 511 extends out of the first box body 10 from the first through hole 171. In the second unlocking position, the ratchet 511 is located on the inner side of the first box body 10.

[0140] In the second unlocked position, the ratchet 511 does not protrude from the outer wall surface of the first box body 10. For the second lock component 50 installed on the first box side wall 130, in the second unlocked position, the ratchet 511 does not protrude from the outer wall surface of the first box side wall 130. For the second lock component 50 installed on the second box side wall 140, in the second unlocked position, the ratchet 511 does not protrude from the outer wall surface of the second box side wall 140.

[0141] A structure cooperating with the ratchet 511 of the locking rod 51 is provided on the cabinet 2 on which the chassis 100 is installed, so that the second locking component 50 can lock the first box body 10 and the cabinet 2 .

[0142] In a specific implementation, after the chassis 100 is installed in the cabinet 2, the cabinet 2 has a first cabinet wall surface corresponding to the first box side wall 130 of the first box body 10, and a second cabinet wall surface corresponding to the second box side wall 140 of the first box body 10, and grooves are provided on both the first cabinet wall surface and the second cabinet wall surface. The second lock component 50 is in the second locking position, and the ratchet 511 of the lock rod 51 extends from the first through hole 171 and can be inserted into the groove of the cabinet 2 to achieve locking of the first box body 10 and the cabinet 2.

[0143] In this embodiment, the second lock component 50 may further include a mounting seat 52, which is fixedly connected to the first box body 10. The mounting seat 52 is fixed to the inner side of the box side wall of the first box body 10, and the lock rod 51 is rotatably connected to the mounting seat 52. The mounting seat 52 has a second through hole 523, which is connected to the first through hole 171 of the first box body 10, so that when the lock rod 51 rotates, the ratchet 511 of the lock rod 51 can extend out of the first box body 10 from the second through hole 523 and the first through hole 171. It can be understood that after the mounting seat 52 is fixed to the first box body 10, the position of the second through hole 523 corresponds to the position of the first through hole 171. In this way, the assembly of the lock rod 51 is convenient.

[0144] In this embodiment, the second locking component 50 also includes a fixing component 54 and an elastic component 55. The fixing component 54 is fixed to the mounting seat 52. The locking rod component 51 is located between the fixing component 54 and the mounting seat 52. One end of the elastic component 55 abuts against the fixing component 54, and the other end of the elastic component 55 abuts against the locking rod component 51. The elastic component 55 can keep the locking rod component 51 in the second locking position.

[0145] In use, the locking rod 51 is in the second locking position, and an external force is applied to the locking rod 51 to rotate the locking rod 51 toward the second unlocking position. During the rotation, the elastic member 5 can accumulate elastic deformation energy. After the external force applied to the locking rod 51 is removed, the locking rod 51 can rotate toward the second locking position under the elastic deformation energy of the elastic member 5.

[0146] Such an arrangement can ensure the locking effect of the second locking component 50 on the first box body 10 and the cabinet 2 .

[0147] The second lock component 50 is mounted on the first box body 10 through the mounting seat 52. In this way, the second lock component 50 is a modular structure, which is convenient for assembly and maintenance.

[0148] The fixing member 54 is fixedly connected to the mounting seat 52, and the locking rod 51 is located between the fixing member 54 and the mounting seat 52. In this way, it is convenient to set the elastic member 55 between the locking rod 51 and the fixing member 54, and the rotation range of the locking rod 51 can also be limited to prevent the locking rod 51 from affecting the functional unit installed in the first box body 10.

[0149] Exemplarily, the fixing member 54 and the mounting seat 52 may be detachably connected using fasteners such as screws.

[0150] The mounting base 52 and the first box body 10 can be connected in a detachable manner to facilitate maintenance or replacement of the second lock component 50. Exemplarily, the mounting base 52 can be provided with a third connection hole 521, and the first box body 10 can be provided with a first mounting hole 181 corresponding to the position of the third connection hole 521, and the mounting base 52 and the first box body 10 are fixedly connected by fasteners such as screws that penetrate the first mounting hole 181 and the third connection hole 521. The first mounting hole 181 is located on the first box side wall 130 or the second box side wall 140 of the first box body 10.

[0151] The locking rod 51 can be rotatably connected to the mounting seat 52 via the second rotating shaft 53. The locking rod 51 can be in a strip or rod structure, and the locking rod 51 includes a first rod end 5101 and a second rod end 5102 that are opposite to each other.

[0152] The rotation center line of the locking rod 51 , that is, the axial direction of the second rotating shaft 53 is parallel to the third direction Z, and the locking rod 51 rotates in a plane constructed by the first direction X and the second direction Y.

[0153] In some examples, the second shaft 53 is located between the first rod end 5101 and the second rod end 5102 and is disposed close to the first rod end 5101, and the ratchet 511 of the locking rod 51 is disposed close to the second rod end 5102 relative to the second shaft 53. Applying force to the first rod end 5101 or the second rod end 5102 can cause the locking rod 51 to rotate around the second shaft 53.

[0154] In some examples, the first box body 10 includes an open end, which is a first end 101 of the first box body 10 , and the second locking member 50 is disposed close to the open end of the first box body 10 to facilitate operation of the second locking member 50 .

[0155] The first rod end 5101 of the locking rod 51 is located in the accommodating cavity 10a of the first box body 10, and the second rod end 5102 can extend out of the first box body 10 from the opening end of the first box body 10. Fig.10 As shown, it is convenient for the user to apply force to the second rod end 5102.

[0156] On the basis that the locking rod 51 is installed on the mounting seat 52, the mounting seat 52 can be provided with an opening 524, and the second rod end 5102 of the locking rod 51 corresponds to the position of the opening 524. The end of the opening 524 is provided on the mounting seat 52 to extend out of the first box body 10. In this way, the second rod end 5102 is in an exposed state, which is convenient for the user to apply force to the second rod end 5102.

[0157] In a specific implementation, a positioning structure is provided on at least one of the fixing member 54 and the locking rod member 51 to limit the position of the elastic member 55 to prevent the elastic member 55 from being offset and unable to function.

[0158] In some examples, the positioning structure includes a positioning column 541 provided on the fixing member 54 and a positioning hole 513 provided on the locking rod member 51, one end of the elastic member 55 is sleeved on the positioning column 541, and the other end of the elastic member 55 is inserted into the positioning hole 513, such as Fig.13 and Fig.15 .

[0159] The positioning hole 513 of the locking rod 51 can be set at the position where the ratchet 511 is located. The thickness of the ratchet 511 is relatively large, which facilitates the setting of the positioning hole 513.

[0160] In some other examples, the positioning structure may include two positioning columns, which are respectively disposed on the locking rod 51 and the fixing member 54 , and the two ends of the elastic member 55 are respectively sleeved on the two positioning columns.

[0161] In other examples, the positioning structure may include two positioning holes, which are respectively provided on the locking rod 51 and the fixing member 54 , and the two ends of the elastic member 55 are respectively inserted into the two positioning holes.

[0162] In other examples, the positioning structure may only include a positioning column or a positioning hole provided on the locking rod member 51 or the fixing member 54 .

[0163] Exemplarily, the elastic member 55 may be a spring.

[0164] Please refer to Fig.17 and Fig.18 , Fig.17 It is a partial cross-sectional view of the first locking component and the second locking component at the sides where the first box side wall and the third box side wall are located in the embodiment of the present application. Fig.18 It is a partial cross-sectional view of the first locking component and the second locking component at the side where the second box side wall and the fourth box side wall are located in the embodiment of the present application. Fig.17 The first locking component 40 is in the first unlocking position, and the second locking component 50 is in the second locking position. Fig.18 The first locking component 40 is in the first locking position, and the second locking component 50 is in the second unlocking position.

[0165] In this embodiment, the first locking component 40 and the second locking component 50 can be linked and configured such that: during the process of the first locking component 40 locking the first box body 10 and the second box body 20, force can be applied to the second locking component 50 to release the lock between the first box body 10 and the cabinet 2.

[0166] Thus, in actual applications, when the chassis 100 needs to be pulled out of the cabinet 2 as a whole, only the first lock component 40 needs to be operated to simultaneously unlock the first box body 10 and the cabinet 2 and lock the first box body 10 and the second box body 20, which is easy to operate.

[0167] Due to the setting of the elastic member 55 of the second locking component 50, when the first locking component 40 switches to the first unlocking position for releasing the lock of the first box body 10 and the second box body 20, the force applied to the second locking component 50 by the first locking component 40 disappears. At this time, the second locking component 50 can be reset to the second locking position under the action of the elastic member 55.

[0168] In a specific implementation, when the linkage member 42 of the first locking member 40 is inserted into the first locking frame 43, that is, when the linkage member 42 moves in the direction of locking the first box body 10 and the second box body 20, Figure 6 , an unlocking force can be applied to the lock rod 51 of the second lock component 50 so that the lock rod 51 rotates toward the second unlocking position, such as Fig.16 and Fig.18 .

[0169] The linkage member 42 can apply force to the first rod end 5101 of the locking rod member 51. The first rod end 5101 of the locking rod member 51 is located above the first locking frame 43, so that the linkage member 42 can apply force to the first rod end 5101 when inserted into the first locking frame 43. Figure 6 , Fig.16 and Fig.18 understand.

[0170] The end of the linkage member 42 inserted into the first lock frame 43 may be provided with a first wedge-shaped surface 421, such as Figure 6 The first rod end 5101 of the locking rod member 51 is provided with a second wedge surface 512, such as Fig.12 When the linkage member 42 is inserted into the first lock frame 43 along the third direction Z, the first wedge surface 421 may contact the second wedge surface 512 and utilize the wedge-shaped mating surface to apply force to the first rod end 5101 of the locking rod member 51, so that the locking rod member 51 may rotate around the second rotating shaft 53.

[0171] Combination Figure 7 , Fig.15 and Fig.17 The linkage member 42 of the first lock component 40 is in the first unlocking position, and the linkage member 42 is not inserted into the first lock frame 43. At this time, the second lock component 50 is maintained in the second locking position, and the ratchet 511 of the lock rod 51 extends out of the first box body 10 through the first through hole 171.

[0172] Combination Figure 5 , Figure 6 , Fig.16 and Fig.18 When a force is applied to the toggle member 41 of the first lock component 40 to drive the linkage member 42 to insert into the first lock frame 43, the first wedge surface 421 of the linkage member 42 contacts the second wedge surface 512 of the lock rod 51, and a force is applied to the second wedge surface 512 during the insertion into the first lock frame 43, so that the lock rod 51 rotates around the second rotation axis 53 to Fig.16In the position shown, the locking rod 51 rotates clockwise, the ratchet 511 retracts from the first through hole 171 into the first box body 10 and compresses the elastic member 55, so that the second locking component 50 is in the second unlocking position.

[0173] When the toggle member 41 of the first lock member 40 is applied with force to drive the linkage member 42 to escape from the first lock frame 43, the force applied by the linkage member 42 to the second wedge-shaped surface 512 of the lock rod 51 disappears, and under the action of the elastic member 55, the lock rod 51 can rotate in the opposite direction to Fig.16 In the direction shown, the locking rod 51 rotates counterclockwise to drive the ratchet 511 to extend from the first through hole 171 to the outside of the first box body 10, so that the second locking component 50 is in the second locking position.

[0174] The second rod end 5102 of the locking rod 51 of the second locking component 50 is in an exposed state. In a scenario where the first box 10 is not nested with the second box 20, the user can apply force to the second rod end 5102 to move the locking rod 51 to achieve an unlocking operation between the first box 10 and the cabinet 2.

[0175] The specific structure of the extraction-assisting component 30 is introduced below.

[0176] Please refer to Fig.19 and Fig. 20 , Fig.19 This is a partial enlarged view of the position of the pull-out assisting component of the second box body on the side where the fourth box side wall is located in the embodiment of the present application. Fig. 20 for Fig.19 The exploded schematic diagram of the second box body and the extraction-assisting component is shown. Fig.19 and Fig. 20 In order to clearly illustrate the structure of the extraction-assisting component 30 , the first box body 10 is not shown.

[0177] In this embodiment, the extraction assisting component 30 includes a wrench 31, which is rotatably connected to the second box body 20, and the wrench 31 includes a protruding arm 311. The first box body 10 has a third through hole 173 (see Fig. 9 ), the protruding arm 311 of the wrench 31 can extend from the third through hole 173 and cooperate with the limiting structure to generate a force applied to the second box body 20.

[0178] In an application scenario, the chassis 100 is not installed in the cabinet 2 of the server 1 and is in a relatively independent state. In this state, there is a need to perform plugging and unplugging operations on the second box 20. The chassis 100 can be provided with a limit fixture 60 to assist the plugging and unplugging operations of the second box 20. The limit fixture 60 is detachably connected to the first box 10, and a limit structure that cooperates with the wrench 31 is provided on the limit fixture 60.

[0179] In a specific implementation, the limiting structure of the limiting tool 60 is a limiting recess 61 , and the limiting recess 61 has a first limiting wall 611 and a second limiting wall 612 .

[0180] The protruding arm 311 of the wrench 31 installed on the second box body 20 can be inserted into the limiting recess 61 of the limiting tool 60 after extending from the third through hole 173 of the first box body 10 .

[0181] The operation of the extraction-assisting component 30 is described below by taking the insertion and extraction of the second box body 20 relative to the first box body 10 .

[0182] When the wrench 31 rotates relative to the second box body 20, the protruding arm 311 can move between the first limiting wall 611 and the second limiting wall 612, and is configured as follows: when the wrench 31 rotates until the protruding arm 311 abuts against the second limiting wall 612, a force along the insertion direction can be applied to the second box body 20, so as to facilitate the plugging of the connector in the second box body 20 with the connector in the first box body 10; when the wrench 31 rotates until the protruding arm 311 abuts against the first limiting wall 611, a force along the extraction direction can be applied to the second box body 20, so as to facilitate the disconnection of the connector in the second box body 20 with the connector in the first box body 10.

[0183] In a specific implementation, the rotation center line of the wrench 31 relative to the second box body 20 is parallel to the third direction Z, and the first limiting wall 611 and the second limiting wall 612 of the limiting recess 61 are arranged along the second direction Y.

[0184] The wrench 31 with the protruding arm 311 can form a lever structure, and the wrench 31 can be provided with two protruding arms 311. According to the plugging and unplugging requirements, each protruding arm 311 can be inserted into the limiting recess 61 in sequence to generate sufficient plugging and unplugging force. The two protruding arms 311 are respectively a first protruding arm 3111 and a second protruding arm 3112.

[0185] exist Fig.19 and Fig. 20From the perspective shown, when the wrench 31 rotates clockwise, the second protruding arm 3112 is first inserted into the limiting recess 61, and the second protruding arm 3112 moves toward the second limiting wall 612 until it abuts against the second limiting wall 612. The force between the second protruding arm 3112 and the second limiting wall 612 can cause the second box body 20 to move along the second direction Y toward the inside of the first box body 10. When the wrench 31 continues to rotate clockwise, the second protruding arm 3112 disengages from the limiting recess 61, and the first protruding arm 3111 is inserted into the limiting recess 61 again. The first protruding arm 3111 is inserted into the limiting recess 61 and moves toward the second limiting wall 612 until it abuts against the second limiting wall 612. The action force between the first protruding arm 3111 and the second limiting wall 612 can make the second box body 20 continue to move toward the inside of the first box body 10 along the second direction Y. In this way, through the relay cooperation between the second protruding arm 3112 and the first protruding arm 3111, the second box body 20 can be conveniently installed in the first box body 10.

[0186] exist Fig.19 and Fig. 20 From the perspective shown, when the wrench 31 rotates counterclockwise, the first protruding arm 3111 is first inserted into the limiting recess 61, and the first protruding arm 3111 moves toward the first limiting wall 611 until it abuts against the first limiting wall 611. The force between the first protruding arm 3111 and the first limiting wall 611 can cause the second box body 20 to move along the second direction Y toward the outside of the first box body 10. When the wrench 31 continues to rotate counterclockwise, the first protruding arm 3111 disengages from the limiting recess 61, and the second protruding arm 3112 is inserted into the limiting recess 61 again. The second protruding arm 3112 is inserted into the limiting recess 61 and moves toward the first limiting wall 611 until it abuts against the first limiting wall 611. The action force between the second protruding arm 3112 and the first limiting wall 611 can make the second box body 20 continue to move toward the outside of the first box body 10 along the second direction Y. In this way, through the relay cooperation of the first protruding arm 3111 and the second protruding arm 3112, the second box body 20 can be easily pulled out of the first box body 10.

[0187] The above description takes the example that the wrench 31 is provided with two protruding arms 311. In actual application, only one protruding arm 311 can be provided on the wrench 31. If space permits, the wrench 31 can also be provided with more protruding arms 311. The operation process is similar to the above and will not be repeated.

[0188] The wrench 31 has a hinge hole 312 , and a pin 32 can be passed through the hinge hole 312 to be hinged to the second box body 20 , so that the wrench 31 can rotate relative to the second box body 20 around the pin 32 .

[0189] In some examples, the extraction-assisting component 30 includes two wrenches 31, and the two wrenches 31 are arranged along the second direction Y, that is, wrenches 31 are provided at both ends of the second box body 20 along the second direction Y. The extraction-assisting component 30 also includes a handle 33, and the handle 33 extends along the second direction Y, and the handle 33 connects the two wrenches 31. In this way, the user can hold the handle 33 to drive the two wrenches 31 to rotate synchronously, which is convenient for operation. In the case where two wrenches 31 are arranged along the second direction Y, during the plugging and unplugging operation, the rotation directions of the two wrenches 31 are opposite. Still taking the plugging and unplugging of the second box body 20 relative to the first box body 10 as an example, combined with Figure 4 It is understood that when the second box body 20 needs to be inserted into the first box body 10, the wrench 31 of the auxiliary extraction component 30 installed near the third box side wall 230 rotates counterclockwise, and the wrench 31 of the auxiliary extraction component 30 installed near the fourth box side wall 240 rotates clockwise. When the second box body 20 needs to be pulled out of the first box body 10, the wrench 31 of the auxiliary extraction component 30 installed near the third box side wall 230 rotates clockwise, and the wrench 31 of the auxiliary extraction component 30 installed near the fourth box side wall 240 rotates counterclockwise.

[0190] In some examples, the extraction-assisting component 30 further includes a connecting shaft 34 and a latch 35, wherein the connecting shaft 34 extends along the second direction Y and is inserted into the handle 33, and the latch 35 is sleeved on the connecting shaft 34, and the latch 35 can be used to engage with the second box 20 to limit the relative position of the handle 33 and the second box 20 after the second box 20 is inserted into the first box 10. This arrangement can prevent the handle 33 from driving the wrench 31 to rotate or the second box 20 from being pulled out of the first box 10 due to erroneous operation when the second box 20 does not need to be pulled out.

[0191] like Fig.19 and Fig. 20 As shown, the extraction aid component 30 is in a state where the second box body 20 has been installed on the first box body 10, and the handle 33 is close to the fifth box side wall 250 of the second box body 20. A snap-fit ​​structure that cooperates with the snap-fit ​​component 35 can be provided on the fifth box side wall 250. After the handle 33 drives the wrench 31 to rotate to a state where the first protruding arm 3111 abuts against the second limiting wall 612, the snap-fit ​​component 35 of the handle 33 can snap-fit ​​with the fifth box side wall 250.

[0192] In a specific implementation, a torsion spring 36 can be provided between the latch 35 and the handle 33. The torsion spring 36 can be sleeved on the connecting shaft 34. One arm of the torsion spring 36 abuts against the handle 33, and the other arm of the torsion spring 36 can abut against the latch 35. The torsion spring 36 is configured to keep the latch 35 in a state of being latched with the second box body 20.

[0193] The latch 35 may be provided with a pressing portion, and the user may apply force to the latch 35 through the pressing portion to rotate the latch 35 around the connecting shaft 34 to overcome the elastic force of the torsion spring 36, thereby disconnecting the latch 35 from the second box body 20, releasing the limit between the handle 33 and the second box body 20, and conveniently rotating the wrench 31 to pull out the second box body 20.

[0194] In some examples, the limiting fixture 60 may be a plate-shaped structure, and the limiting fixture 60 may be detachably connected to the first box body 10 by fasteners such as screws. Fig.10 , Fig.19 and Fig. 20 A second mounting hole 182 is provided on the first box body 10, and a fixing hole 62 matching the position of the second mounting hole 182 is provided on the limiting fixture 60. The limiting fixture 60 and the first box body 10 are connected by fasteners passing through the fixing hole 62 and the second mounting hole 182.

[0195] The limiting fixture 60 is connected to the outer side of the first box side wall 130 or the second box side wall 140 of the first box body 10. When the extraction assisting component 30 is provided with two wrenches 31, the limiting fixture 60 matched with the two wrenches 31 can be an integral structural part, which can simplify the number of parts and facilitate assembly.

[0196] Recombination Figure 3 , Figure 4 and Fig.11 The limiting tool 60 can also be fixed to the mounting seat 52 of the second locking component 50 at the same time, and a fourth connecting hole 522 matching the second mounting hole 182 and the fixing hole 62 is provided on the mounting seat 52.

[0197] In another application scenario, the chassis 100 is installed in the cabinet 2 of the server 1. In this scenario, the aforementioned limiting tool 60 is not installed on the first box body 10 of the chassis 100. The limiting structure that cooperates with the protruding arm 311 of the wrench 31 of the auxiliary extraction component 30 is arranged on the cabinet wall of the cabinet 2. A limiting groove extending along the second direction Y can be provided on the cabinet wall of the cabinet 2. The limiting groove has two groove side walls arranged along the second direction Y. The protruding arm 311 of the wrench 31 extends from the third through hole 173 of the first box body 10 and is inserted into the limiting groove of the cabinet 2. When the wrench 31 is rotated, the protruding arm 311 is used to abut against the groove side wall of the limiting groove to apply a force to the second box body 20.

[0198] The above Figures 1 to 20 In the embodiment mainly introducing the server node 3 shown, the second box body 20 is arranged close to the first box bottom wall 120 of the first box body 10. In other embodiments, the second box body 20 can also be arranged close to the first box top wall 110 of the first box body 10. The relevant structural arrangement can be adaptively adjusted and will not be repeated here.

[0199] An embodiment of the present application further provides a server, which includes a cabinet and the server node introduced in the above embodiment, and the server node can be installed in the cabinet.

[0200] It should be understood that other functional components of the server are not the core invention of this application, and those skilled in the art can implement them based on traditional technologies, so they will not be described in detail herein.

[0201] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
