[0002] Existing main units that require pushing during installation or pulling during disassembly generally have a handle structure design. However, the handle structure of the existing main units is complex, inconvenient to operate, has low efficiency in pushing or pulling, and occupies a lot of space, affecting the use effect. Summary of the Invention

[0004] In a first aspect, this application provides a handle structure, disposed on a body that needs to be pushed or pulled, and includes;

[0005] The rotating part has its first end rotatably connected to the main body;

[0006] The handle is fixed to the second end of the rotating part and is used to drive the rotating part to rotate and to push and pull the main body;

[0007] A limiting part is provided on the rotating part and is used to cooperate with the main body to limit the rotation angle of the rotating part;

[0008] A damping part is disposed between the first end of the rotating part and the main body, and is used to suspend the rotating part at any rotating position within its rotation angle.

[0009] As a preferred embodiment of the above solution, the damping part includes a bottom surface, a flanged surface, and a damping pad, with the flanged surface and the damping pad disposed on the bottom surface, and the bottom surface connected to the main body.

[0010] A connecting hole is formed on the rotating part, the connecting hole includes a beveled part, the flanged part passes through the connecting hole and expands to fit tightly against the beveled part, and the rotating part abuts against the damping pad.

[0011] As a preferred embodiment of the above solution, the connecting hole also includes a stepped portion connected to the inclined surface. After the flanged surface expands, it first adheres tightly to the inclined surface and then adheres tightly to the stepped portion.

[0012] As a preferred embodiment of the above solution, the limiting part includes a limiting inclined side and a limiting protrusion, the limiting inclined side is formed on the side wall of the rotating part, and the limiting protrusion is formed on the first end side wall of the rotating part.

[0013] The limiting bevel and limiting protrusion cooperate with the main body to limit the rotation of the rotating part to the minimum and maximum angles relative to the main body.

[0014] As a preferred embodiment of the above solution, the rotating part includes a vertical part and a horizontal part, with the first end of the rotating part disposed at one end of the vertical part and the second end of the rotating part disposed at the end of the horizontal part away from the vertical part.

[0015] A limiting oblique edge is formed at the first connection between the vertical part and the horizontal part, and a connecting oblique edge is formed at the second connection between the vertical part and the horizontal part, extending to the second end of the rotating part.

[0016] Secondly, a node module is provided, including a main body and the handle structure as described above. The main body includes a mounting sidewall, one end of which is formed with a mounting through hole, and a damping part is disposed between the mounting through hole and the first end of the rotating part.

[0017] As a preferred embodiment of the above solution, a limiting post and a limiting protrusion are formed on the mounting side wall, and a limiting notch is formed on the limiting protrusion. The limiting post and the limiting notch respectively cooperate with the limiting part to limit the rotation angle of the rotating part, and:

[0018] When the limiting part abuts against the limiting post, the rotating part rotates to the minimum angle relative to the mounting side wall. When the limiting part abuts against the limiting notch, the rotating part rotates to the maximum angle relative to the mounting side wall.

[0019] Thirdly, a server is provided, including a chassis and the node module as described above. The chassis includes a chassis side wall and a node support plate. The node support plate is fixed within the chassis space enclosed by the chassis side wall and is used to support the node module. The main body is pushed into or pulled out of the chassis space on the node support plate through the handle structure of the node module.

[0020] As a preferred embodiment of the above solution, the limiting part of the handle structure includes a first protrusion and a second protrusion formed on the edge of the rotating part, the second protrusion being located between the first protrusion and the handle part, and a stop post being formed on the side wall of the chassis.

[0021] When the main body is pushed into the chassis space through the handle structure, the rotating part rotates until the first protrusion abuts against the stop post and continues to rotate in the same direction to assist in pushing the main body in.

[0022] When the main body is pulled out into the chassis space via the handle structure, the rotating part rotates until the second protrusion abuts against the node support plate and continues to rotate in the same direction to assist in pulling out the main body.

[0023] As a preferred embodiment of the above solution, the limiting part further includes a recessed part, which is formed between the first protrusion and the second protrusion. Before the rotating part rotates to the point where the first protrusion abuts against the stop post, the recessed part moves to the stop post first, and the second protrusion abuts against the stop post.

[0024] The second protrusion has an arc-shaped surface. The rotating part rotates until the arc-shaped surface abuts against the node support plate and continues to rotate in the same direction to assist in the pulling out of the main body.

[0025] As a preferred embodiment of the above solution, the handle portion of the handle structure includes a base and a locking element slidably disposed on the base. The locking element includes a sliding plate, a hook, and an elastic portion. The elastic portion connects the base and the sliding plate, and the hook is disposed on the sliding plate.

[0026] The chassis also includes a case ear fixed to one end of the chassis. The case ear has a connecting groove and a limiting surface that are connected to each other. The hook and the connecting groove have a first inclined surface and a second inclined surface that are matched with each other, respectively.

[0027] When the handle is fixedly connected to the ear of the box, the first inclined plane slides over the second inclined plane and returns to its original position through the sliding of the slide plate and the elastic force of the elastic part, and the hook is placed on the limiting surface.

[0028] As a preferred embodiment of the above solution, a mounting groove is formed on the base, the sliding plate is slidably disposed in the mounting groove, a plurality of guide posts and a pair of flanges are formed on the mounting groove, and the sliding plate is inserted between the pair of flanges;

[0029] Insertion posts are formed on the slide plate and a pair of flanges. The elastic part is inserted into the insertion posts, and the two ends of the elastic part are respectively fixed to the pair of flanges and the slide plate. Multiple grooves are formed on the slide plate, which are respectively inserted into multiple guide posts.

[0030] As a preferred embodiment of the above scheme, a positioning post is formed on the base, and a positioning through hole is formed on the ear of the box. A first guide slope and a second guide slope that cooperate with each other are formed on the positioning post and the positioning through hole, respectively. The positioning post passes through the positioning through hole to achieve positioning between the handle and the ear of the box.

[0031] As a preferred embodiment of the above solution, a bent edge and a through groove are formed on the base, and a lever is formed on the side wall of the slide away from the hook, with the lever slidably disposed in the through groove.

[0032] Fourthly, a method for assembling and disassembling a node module is provided, applicable to the server described above, and includes the following steps:

[0033] When installing node modules:

[0034] The handle structure allows the rotating part to be suspended at a rotating position within its rotation angle, and the angle between the rotating part and the main body at this rotating position is 30-60 degrees.

[0035] Place the main body on the node support plate and push the main body into the chassis space through the handle;

[0036] When the second protrusion moves to abut against the stop post, the rotating part rotates toward the main body until the first protrusion abuts against the stop post and continues to rotate to assist the pushing of the main body in.

[0037] After the main body is fully pushed into the chassis space, continue to rotate the rotating part so that the second inclined surface of the hook slides over the first inclined surface of the connecting groove. Through the elastic force of the elastic part, the hook is reset and placed on the limiting surface, thus completing the fixing of the handle structure to the box ear and the installation and fixing of the node module inside the chassis.

[0038] When disassembling the node module:

[0039] Pushing the slide plate compresses the elastic part, and the hook leaves the limiting surface to unlock. At the same time, the rotating part rotates away from the main body. The rotating part rotates until the second protrusion abuts against the node support plate and continues to rotate to assist in pulling out the main body.

[0040] Pull the main body outward from the chassis by using the handle to help it move out of the chassis space.

[0041] With the handle structure of this application, due to the setting of a rotating part and a limiting part, the rotating part can drive the handle to rotate within its limited rotation angle, which makes it convenient to adjust the position of the handle when pushing or pulling the main body, and to rotate and store it when the main body is not needed, reducing the space occupied; by setting a damping part, the rotating part can be suspended at any rotation position within its rotation angle, thereby allowing the handle to be suspended at any rotation position, so that the handle can conveniently and stably push or pull the main body, improving the pushing or pulling efficiency. The structure is simple and the use effect is good.

[0042] With the node module of this application, due to the handle structure set on the mounting side wall, the rotating part 1 can drive the handle to rotate within its limited rotation angle, which makes it convenient to adjust the position of the handle when pushing or pulling the main body, and to rotate and store it on the side of the mounting side wall when the main body is not needed, reducing the space occupied; by setting the damping part, the rotating part can be suspended at any rotation position within its rotation angle, thereby allowing the handle to be suspended at any rotation position, so that the handle can conveniently and stably push or pull the main body, improving the pushing or pulling efficiency. The structure is simple and the use effect is good.

[0043] The server described in this application features a handle structure on the mounting sidewall of the node module. The rotating part can drive the handle to rotate within its limited rotation angle, facilitating adjustment of the handle's position when pushing or pulling the main body, and allowing for rotational storage when the main body is not needed, thus reducing the space occupied by the node module or chassis. By setting a damping part, the rotating part can be suspended at any rotation position within its rotation angle, thereby allowing the handle to be suspended at any rotation position. This enables the handle to conveniently and stably push or pull the main body on the node support plate, improving the efficiency of pushing or pulling. The structure is simple and the performance is good.

[0044] The node module installation and removal method of this application allows for easy insertion of the node module into the server chassis by hovering the handle of the handle structure. When the second protrusion moves to abut against the stop post, the rotating part rotates towards the main body until the first protrusion abuts against the stop post and continues to rotate, facilitating precise mating of the connector at the rear of the main body and the rear of the chassis. After the main body is fully inserted into the chassis, further rotation of the rotating part causes the second inclined surface of the hook to slide over the first inclined surface of the connecting groove. The elastic force of the elastic part causes the hook to reset and lock onto the limiting surface, thus completing the fixing of the handle structure to the ear and the installation and fixing of the node module inside the chassis. This is achieved through the handle structure... The node module, which mates with the chassis, is easy and quick to install. It can also be secured to the chassis via locking fasteners and mounting ears, ensuring quick and easy installation. To disassemble the node module, the sliding plate compresses the elastic part, causing the hook to disengage from the limiting surface and unlock. Simultaneously, the rotating part is rotated away from the main body until the second protrusion abuts against the node support plate and continues to rotate in the same direction, assisting in pulling the main body's connector out of the chassis space. Finally, the handle is used to pull the main body out of the chassis, further assisting in its removal from the chassis space. Thus, the locking fasteners and mounting ears facilitate quick and easy unlocking of the node module, while the handle structure and chassis-mate mechanism facilitate quick and easy removal and disassembly of the node module.

Detailed Implementation

[0058] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0060] As described in the background section, existing main bodies that require pushing during installation or pulling during disassembly generally have a handle structure design. However, the handle structure of the existing main bodies is complex, inconvenient to operate, inefficient when pushing or pulling, and occupies a lot of space, affecting the usability.

[0061] With the development of internet technology, the design of various servers has become increasingly diversified, and performance requirements are becoming more and more stringent, such as for AI servers. One type of server with a special design architecture is called a multi-node server, high-density server, or modular server. This type of server is characterized by containing multiple independent, miniaturized, server-like computing units within a large, shared physical server chassis. Each such computing unit is called a "node chassis" (node, node module), and they are essentially streamlined versions of servers, many of which exhibit blade-like node designs.

[0062] Multi-node servers are designed primarily to meet the needs of large data centers (such as cloud computing and hyperscale computing), including extremely high density: 2, 4, 8, or even more nodes can be accommodated within a standard 2U or 4U high rack space, significantly saving rack space; simplified cabling and deployment: since network and power cables are connected internally, only a few external cables are needed, making deployment and maintenance very convenient and reducing the nightmare of cable management; higher energy efficiency: the shared high-efficiency power supply and cooling system are more efficient than the individual power supplies and fans of numerous individual servers, reducing PUE (Power Usage Effectiveness); convenient centralized management: administrators can manage all nodes in the entire chassis through a single IP address, instead of managing the BMC / IPMI addresses of dozens of independent servers, greatly improving operational efficiency; flexible resource configuration: nodes with different computing and storage specifications can be mixed and configured within the same physical chassis according to business needs.

[0063] A node chassis is typically a hot-swappable drawer-type module that can be directly inserted into the front or rear of the server during installation. Data interconnection is achieved through the high-density ports in the node chassis and the interlocking with the rear window module. During disassembly, it can be directly pulled out from the front or rear of the server. The installation and disassembly of the node chassis require the use of the assisted handle structure on the node chassis.

[0064] However, existing node chassis have complex handle structures, making operation inconvenient, inefficient when pushing or pulling, and space-consuming, thus affecting usability. Furthermore, once installed on a server, the handle structure cannot be effectively organized, further reducing the space utilization of the server chassis. Moreover, the existing handle structure cannot effectively secure the node chassis to the server, limiting its functionality. Additionally, the current node chassis relies entirely on force applied to the handle structure during installation and removal, which can be difficult and strenuous due to the chassis's weight. Furthermore, the installation of the node chassis requires mating the connectors at its rear end with the server chassis's internal components. Pushing the existing node chassis to a certain position requires significant force due to the multiple connectors, which can damage the connectors and is inconvenient due to the operator's effort.

[0065] The handle structure provided in this application is simple in structure and easy to use. It is highly efficient in promoting the installation of the main body or promoting the disassembly of the main body, and occupies little space when in use.

[0066] The node module provided in this application can be easily pushed or pulled by the handle structure, which facilitates the installation and disassembly of the node module. At the same time, the node module occupies little space and has a high degree of neatness within the server.

[0067] The server provided in this application can easily and effortlessly achieve precise connector mating during node module installation, saving time and effort while ensuring that the connectors are not damaged. The cooperation between the ear and handle structure can facilitate the fixing of the node module after installation, making the fixing of the node module convenient. The cooperation between the handle structure and the server chassis makes it easy and effortless to push or pull the node chassis.

[0068] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0069] Example 1

[0070] like Figure 1 , Figure 3 As shown, this application provides a handle structure disposed on a main body 100 that needs to be pushed or pulled, and includes a rotating part 1, a handle part 2, a limiting part 3, and a damping part 4. The first end of the rotating part 1 is rotatably connected to the main body 100. The rotating part 1 includes a vertical part 11 and a horizontal part 12. The first end of the rotating part 1 is disposed at one end of the vertical part 11, and the second end of the rotating part 1 is disposed at the end of the horizontal part 12 away from the vertical part 11. The rotating part 1 may be an integrally formed sheet body and abut against one end of the mounting side wall 101 of the main body 100.

[0071] like Figure 3 , Figure 4 As shown, the handle 2 is fixed to the second end of the rotating part 1 and is used to drive the rotating part 1 to rotate and to push and pull the main body 100. The handle 2 can be a one-piece molded sheet. The handle 2 can be arranged perpendicularly to the rotating part 1.

[0072] like Figure 3 , Figure 4 As shown, a limiting part 3 is provided on the rotating part 1 and is used to cooperate with the main body 100 to limit the rotation angle of the rotating part 1. The limiting part 3 includes a limiting inclined edge 31 and a limiting protrusion 32. The limiting inclined edge 31 is formed on the side wall of the rotating part 1, and the limiting protrusion 32 is formed on the first end side wall of the rotating part 1. The limiting inclined edge 31 and the limiting protrusion 32 cooperate with the main body 100 to limit the rotating part 1 to rotate to the minimum and maximum angles relative to the main body 100, respectively. The limiting inclined edge 31 is formed at the first connection between the vertical part 11 and the horizontal part 12, and a connecting inclined edge 13 is formed at the second connection between the vertical part 11 and the horizontal part 12, extending to the second end of the rotating part 1. The setting of the limiting inclined edge 31 not only facilitates cooperation with the protrusion on the side wall of the main body 100 to limit the rotation angle of the rotating part 1, but also improves the torque transmission effect between the rotating part 1 and the handle part 2.

[0073] For example, such as Figure 3 , Figure 4As shown, the limiting inclined edge 31 and the limiting protrusion 32 can cooperate with the protrusion on the mounting side wall 101 of the main body 100 to limit the rotation of the rotating part 1 to the minimum and maximum angles relative to the main body 100. The minimum angle can be set to 0 degrees, that is, when the limiting inclined edge 31 abuts against the protrusion on the mounting side wall 101 of the main body 100, the angle between the vertical side wall 111 of the vertical part 11 of the rotating part 1 and the main body 100 along the height direction is 0 degrees. Figure 4 As shown, the handle 2 and rotating part 1 are in their retracted positions when the main body 100 is not being pushed or pulled, reducing space occupation and improving the regularity of the arrangement when multiple main bodies 100 and handle structures are linearly arranged. Setting the minimum angle to 0 degrees also prevents excessive rotation of the handle 2 and rotating part 1 during storage, preventing interference fit between the handle 2 and rotating part 1 and the main body 100, which could cause scratches to the main body 100 or the handle 2. The maximum angle can be set to 60 degrees, meaning that when the limiting protrusion 32 abuts against the protrusion on the side wall of the main body 100, the angle between the vertical side wall 111 of the vertical part 11 of the rotating part 1 and the main body 100 along the height direction is 60 degrees. Figure 3 As shown, the handle 2 and the rotating part 1 are in the most convenient position to push or pull the main body 100. It can be understood that when pushing or pulling the main body 100, the rotating part 1 can rotate to a position where the angle between the vertical side wall 111 of its vertical part 11 and the main body 100 along the height direction is 30-60 degrees. At this time, the handle 2 and the rotating part 1 are in the convenient position to push or pull the main body 100.

[0074] like Figure 1 , Figure 3 , Figure 5 As shown, the damping part 4 is disposed between the first end of the rotating part 1 and the main body 100, and is used to suspend the rotating part 1 at any rotating position within its rotation angle. The damping part 4 includes a bottom surface 41, a flanged surface 42, and a damping pad 43. The flanged surface 42 and the damping pad 43 are disposed on the bottom surface 41, which is connected to the main body 100. A connecting hole 14 is formed on the rotating part 1. The connecting hole 14 includes a beveled surface 141. The flanged surface 42 passes through the connecting hole 14 and expands to fit tightly against the beveled surface 141. The rotating part 1 abuts against the damping pad 43 and abuts against one end of the mounting side wall 101 of the main body 100 through the damping pad 43. The connecting hole 14 also includes a stepped part 142 connected to the beveled surface 141. After the flanged surface 42 expands, it first fits tightly against the beveled surface 141 and then fits tightly against the stepped part 142.

[0075] For example, such as Figure 5As shown, a mounting through hole 102 can be provided on the mounting side wall 101 of the main body 100. The bottom surface 41 and the flange surface 42 of the damping part 4 form a damping rivet. The damping rivet rivets the mounting through hole 102 and the rotating part 1, realizing the rotational connection between the rotating part 1 and the mounting side wall 101 of the main body 100. The step part 142 increases the contact area between the flange surface 42 and the connecting hole 14 after the flange surface 42 expands, improving the riveting tightness between the rotating part 1 and the mounting side wall 101 of the main body 100. A step surface 44 is provided on the bottom surface 41. The step surface 44 abuts against the mounting through hole 102 to realize the limiting connection between the damping part 4 and the mounting side wall 101. The flange surface 42 is circular and formed in the middle of the bottom surface 41. The damping pad 43 is annular and fixed on the bottom surface 41 between the flange surface 42 and the step surface 44. The material of the damping pad 43 can be selected as elastic rubber or the like.

[0076] During installation, the damping part 4 is first placed with its bottom surface 41 against the side wall of the main body 100 away from the mounting side wall 101, the stepped surface 44 against the mounting through hole 102, and the flanged surface 42 and the damping pad 43 passing through the mounting through hole 102. Then, the connecting hole 14 of the rotating part 1 is inserted into the flanged surface 42 and the rotating part 1 against the damping pad 43. The flanged surface 42 is then expanded and tightly attached to the inclined surface 141 and the stepped surface 142. The damping pad 43 is assembled between the rotating part 1 and the bottom surface 41, so that there is a gap between the rotating part 1 and the mounting side wall 101 of the main body 100, which will not affect the rotational friction of the rotating part 1. At the same time, the static friction generated by the combination of the damping pad 43 and the damping rivet is sufficient to resist the gravitational torque of the rotating part 1 and the handle part 2, thereby enabling the rotating part 1 and the handle part 2 to be suspended at any position within the limited rotation angle of the rotating part 1.

[0077] The handle 2 and the rotating part 1 can be made of lightweight materials such as alloy or plastic parts, and the handle 2 is a certain distance away from the damping part 4 to form a low load and low torque usage scenario, so as to ensure that the rotating part 1 and the handle 2 can be hovered at any position within the limited rotation angle of the rotating part 1.

[0078] With the handle structure of this application, due to the setting of the rotating part 1 and the limiting part 3, the rotating part 1 can drive the handle part 2 to rotate within its limited rotation angle, which makes it convenient to adjust the position of the handle part 2 when pushing or pulling the main body 100, and to rotate and store it when the main body 100 is not needed, thus reducing the space occupied; by setting the damping part 4, the rotating part 1 can be suspended at any rotation position within its rotation angle, thereby allowing the handle part 2 to be suspended at any rotation position, so that the handle part 2 can conveniently and stably push or pull the main body 100, improve the pushing or pulling efficiency, and has a simple structure and good use effect.

[0080] This application provides a node module, such as Figure 3 As shown, the device includes a main body 100 and a handle structure as described in Embodiment 1. The main body 100 includes a mounting sidewall 101, one end of which is formed with a mounting through hole 102. A damping part 4 is disposed between the mounting through hole 102 and the first end of the rotating part 1.

[0081] like Figure 3 As shown, a limiting post 103 and a limiting protrusion 104 are formed on the mounting sidewall 101. A limiting notch 105 is formed on the limiting protrusion 104. The limiting post 103 and the limiting notch 105 cooperate with the limiting part 3 to limit the rotation angle of the rotating part 1. When the limiting part 3 abuts against the limiting post 103, the rotating part 1 rotates to the minimum angle relative to the mounting sidewall 101. When the limiting part 3 abuts against the limiting notch 105, the rotating part 1 rotates to the maximum angle relative to the mounting sidewall 101.

[0082] like Figure 3 , Figure 4 As shown, the protrusion on the mounting sidewall 101 includes a limiting post 103 and a limiting protrusion 104. The limiting post 103 corresponds to and engages with the limiting inclined edge 31, and the limiting notch 105 on the limiting protrusion 104 corresponds to and engages with the limiting protrusion 32, thereby limiting the rotation of the rotating part 1 to the minimum and maximum angles relative to the main body 100. When the rotating part 1 rotates to the point where the limiting inclined edge 31 abuts against the limiting post 103, the minimum angle of rotation of the rotating part 1 to the relative body 100 is achieved. The minimum angle can be set to 0 degrees. Figure 4 As shown, the handle 2 and rotating part 1 are in their retracted position when not pushing or pulling the main body 100, reducing space occupation and improving the regularity of the node module arrangement when multiple node modules are linearly arranged. Simultaneously, setting the minimum angle to 0 degrees prevents excessive rotation of the handle 2 and rotating part 1 during retraction, preventing interference fit between the handle 2 and rotating part 1 and the main body 100, which could cause scratches to the main body 100. When the limiting protrusion 32 abuts against the limiting notch 105, the rotating part 1 rotates to its maximum angle relative to the main body 100. The maximum angle can be set to 60 degrees. Figure 3 As shown, the handle 2 and the rotating part 1 are in the most convenient position for pushing or pulling the main body 100, allowing for the push-to-install or pull-to-remove of the node module. It can be understood that when pushing or pulling the main body 100, the rotating part 1 can rotate to a position where the angle between the vertical sidewall 111 of its vertical part 11 and the main body 100 along the height direction is 30-60 degrees. At this time, the handle 2 and the rotating part 1 are in a position that facilitates pushing or pulling the main body 100.

[0083] With the node module of this application, since a handle structure is provided on the mounting sidewall 101, the rotating part 1 can drive the handle part 2 to rotate within its limited rotation angle, which makes it convenient to adjust the position of the handle part 2 when pushing or pulling the main body 100, and to rotate and store it on the side of the mounting sidewall 101 when the main body 100 is not needed, thus reducing the space occupied; by providing a damping part 4, the rotating part 1 can be suspended at any rotation position within its rotation angle, thereby allowing the handle part 2 to be suspended at any rotation position, so that the handle part 2 can conveniently and stably push or pull the main body 100, improving the pushing or pulling efficiency. The structure is simple and the use effect is good.

[0084] Example 3

[0085] This application provides a server, such as Figures 7 to 9 As shown, the system includes a chassis 200 and a node module as described in Embodiment 2. The chassis 200 includes a chassis side wall 201 and a node support plate 202. The node support plate 202 is fixed within the chassis space enclosed by the chassis side wall 201 and is used to support the node module. The main body 100 is pushed into or pulled out of the chassis space on the node support plate 202 through the handle structure of the node module. For example, multiple sets of node support plates 202 can be arranged within the chassis space, and the node support plates 202 can be linearly arranged to support multiple sets of node modules linearly arranged and installed within the chassis space.

[0086] like Figure 3 , Figure 8 As shown, the limiting part 3 of the handle structure includes a first protrusion 33 and a second protrusion 34 formed on the edge of the rotating part 1. The first protrusion 33 can be located at the same location as the limiting protrusion 32 on the rotating part 1, and the second protrusion 34 is located between the first protrusion 33 and the handle part 2. A stop post 203 is formed on the side wall 201 of the chassis. The limiting part 3 also includes a recessed part 35, which is formed between the first protrusion 33 and the second protrusion 34. When the main body 100 is pushed into the chassis space through the handle structure, the recessed part 35 first moves to the stop post 203, and the second protrusion 34 abuts against the stop post 203. Then the rotating part 1 rotates until the first protrusion 33 abuts against the stop post 203 and continues to rotate in the same direction. The stop post 203 generates a reverse force on the first protrusion 33 to help the rear end of the main body 100 to accurately mate with the connector at the rear end of the chassis space after the main body 100 is pushed in, which is convenient and labor-saving, while ensuring that the connector is not damaged.

[0087] For example, multiple stop posts 203 corresponding to the node support plate 202 can be formed on the side wall 201 of the chassis, so as to correspond to the first protrusion 33 of the corresponding node module respectively, so as to facilitate the interface of the corresponding main body 100 at the rear end.

[0088] like Figure 3 , Figure 4As shown, the second protrusion 34 has an arcuate surface 341. When the main body 100 is pulled out into the chassis space via the handle structure, it first rotates via the rotating part 1 until the arcuate surface 341 abuts against the node support plate 202 and continues to rotate in the same direction. The node support plate 202 generates a counterforce on the second protrusion 34 to help the connector of the main body 100 be pulled out from the rear end of the chassis space. Then, the main body 100 is pulled out of the chassis space via the handle part 2. The arcuate surface 341 is more conducive to the contact between the second protrusion 34 and the node support plate 202 so that the node support plate 202 generates a counterforce on the second protrusion 34.

[0089] like Figure 1 As shown, the handle portion 2 of the handle structure includes a base 21 and a locking member 22 slidably disposed on the base 21. The locking member 22 includes a slide plate 221, a hook 222, and an elastic portion 223. The elastic portion 223 connects the base 21 and the slide plate 221, and the hook 222 is disposed on the slide plate 221. Figure 6 , Figure 8 As shown, the chassis 200 also includes a lug 5 fixed to one end of the chassis 200. The lug 5 has a connecting groove 51 and a limiting surface 52. A first inclined surface 224 and a second inclined surface 511 are respectively formed on the hook 222 and the connecting groove 51. The second inclined surface 511 and the limiting surface 52 are formed on opposite side walls of the lug 5. When the handle 2 is fixedly connected to the lug 5, the first inclined surface 224 slides past the second inclined surface 511 and returns to its original position due to the sliding of the slide plate 221 and the elastic force of the elastic part 223, and the hook 222 is engaged with the limiting surface 52.

[0090] like Figure 2 As shown, a mounting groove 211 is formed on the base 21, and a sliding plate 221 is slidably disposed in the mounting groove 211. Multiple guide posts 212 and a pair of flanges 213 are formed on the mounting groove 211, and the sliding plate 221 is inserted between the pair of flanges 213. Insertion posts 214 are formed on the sliding plate 221 and the pair of flanges 213. An elastic portion 223 is inserted into the insertion post 214, and both ends of the elastic portion 223 are respectively fixed to the pair of flanges 213 and the sliding plate 221. Multiple sliding grooves 250 are formed on the sliding plate 221, each inserted into one of the multiple guide posts 212.

[0091] like Figure 2 As shown, a positioning post 215 is formed on the base 21, and a positioning through hole 53 is formed on the ear 5. A first guide slope 216 and a second guide slope 531 are respectively formed on the positioning post 215 and the positioning through hole 53. The positioning post 215 passes through the positioning through hole 53 to achieve positioning between the handle 2 and the ear 5. The first guide slope 216, the second guide slope 531, and the second slope 511 can all be set as 45-degree slopes.

[0092] like Figure 1 , Figure 9As shown, a bent edge 217 and a through groove 218 are formed on the base 21. A lever 225 is formed on the side wall of the slide plate 221 opposite to the hook 222, and the lever 225 is slidably disposed in the through groove 218. The bent edge 217 facilitates the rotation of the rotating part 1 by moving the handle 2 and the pushing and pulling of the main body 100. The lever 225 facilitates the unlocking of the locking member 22 by moving the slide plate 221 and the hook 222.

[0093] For example, such as Figure 1 As shown, the through groove 218 is connected to the mounting groove 211. A positioning post 215 is formed on the bent edge 217 near the edge of the mounting groove 211. The handle portion 2 also includes a cover plate 23 and multiple threaded parts 24. The threaded parts 24 can be countersunk screws, and the cover plate 23 can be made of a lightweight material. An opening 231 with a hook 222 is formed on the cover plate 23. Multiple corresponding fixing holes 232 are formed on the cover plate 23 and the base 21. The fixing holes 232 can be tapped holes. After installing the locking element 22 onto the base 21, the cover plate 23 is placed on the surface of the base 21, aligned with the fixing holes 232, and then the threaded parts 24 are fastened into the fixing holes 232. At this point, the assembly of the handle portion 2 is complete.

[0094] For example, such as Figure 2 As shown, the slide plate 221 includes an upper slide plate 226 and a lower slide plate 227. The width of the upper slide plate 226 is greater than the width of the lower slide plate 227. The upper slide plate 226 is inserted into the mounting groove 211 and abuts against the side wall of the mounting groove 211. The lower slide plate 227 abuts against the side walls of a pair of flanges 213 to form upper and lower limits for the slide plate 221. Multiple sliding grooves 250 are formed on the upper slide plate 226 and the lower slide plate 227 respectively. Four insertion posts 214 are provided and are formed on the pair of flanges 213 and the bottom of the upper slide plate 226 on both sides of the lower slide plate 227. The elastic part 223 can be two telescopic springs located on both sides of the lower slide plate 227. The two ends of the telescopic springs are respectively inserted into the corresponding insertion posts 214 to prevent the telescopic springs from tilting. The telescopic springs are located in the middle of the locking member 22 and the base 21, thus ensuring the elastic balance of the slide plate 221 after being subjected to force, and ensuring the smooth locking and unlocking of the locking member 22 and the ear 5.

[0095] For example, such as Figure 2 , Figure 6 , Figure 8As shown, the hook 222 includes a horizontal connecting part 228 and a hook part 229. The connecting part 228 is fixed to the slide plate 221, and the hook part 229 is fixed to the end of the connecting part 228 away from the slide plate 221. A first inclined surface 224 is formed on the side wall of the hook part 229 away from the connecting part 228. The first inclined surface 224 can be set as a 37-degree inclined surface to cooperate more smoothly with the second inclined surface 511. A straight wall 230 is formed on the side wall of the hook part 229 facing the connecting part 228. A receiving groove 240 is formed between the straight wall 230, the connecting part 228 and the slide plate 221. The limiting surface 52 can be a step surface formed on the side wall of the ear 5. When the handle 2 is fixedly connected to the ear 5, the handle 2 is first rotated until the positioning pin 215 passes through the positioning through hole 53 to achieve positioning between the handle 2 and the ear 5. Then, through the elastic force of the elastic part 223, the first inclined surface 224 of the hook 222 slides over the second inclined surface 511 and returns to its original position. The limiting surface 52 is placed in the receiving groove 240 to achieve locking and limiting.

[0096] With the server of this application, since a handle structure is provided on the mounting sidewall 101 of the node module, the rotating part 1 can drive the handle part 2 to rotate within its limited rotation angle, which facilitates the adjustment of the position of the handle part 2 when pushing or pulling the main body 100, and allows for rotation and storage when the main body 100 is not needed, reducing the space occupied by the node module or chassis. By providing a damping part 4, the rotating part 1 can be suspended at any rotation position within its rotation angle, thereby allowing the handle part 2 to be suspended at any rotation position, so that the handle part 2 can conveniently and stably push or pull the main body 100 on the node support plate 202, improving the pushing or pulling efficiency. The structure is simple and the performance is good.

[0097] Example 4

[0098] This application provides a method for assembling and disassembling a node module, applicable to a server as shown in Embodiment 3, such as... Figure 10 As shown, it includes the following steps:

[0099] When installing node modules:

[0100] S1: The handle part 2 of the handle structure causes the rotating part 1 to be suspended in a rotating position within its rotation angle, and the angle between the rotating part 1 and the main body 100 in the rotating position is 30-60 degrees.

[0101] Specifically, the rotating part 1 can be rotated to a position where the vertical side wall 111 of its vertical part 11 and the main body 100 form an angle of 30-60 degrees along the height direction. At this time, the handle part 2 and the rotating part 1 are in a position that facilitates pushing or pulling the main body 100.

[0102] S2: Place the main body 100 on the node support plate 202 and push the main body 100 into the chassis space through the handle 2.

[0103] S3: When the second protrusion 34 moves to abut against the stop post 203, the rotating part 1 rotates toward the main body 100 until the first protrusion 33 abuts against the stop post 203 and continues to rotate to assist the pushing of the main body 100.

[0104] Specifically, when the main body 100 is pushed into the chassis space through the handle structure, the recessed part 35 first moves to the stop post 203, and the second protrusion 34 abuts against the stop post 203. Then the rotating part 1 rotates until the first protrusion 33 abuts against the stop post 203 and continues to rotate in the same direction. The stop post 203 generates a reverse force on the first protrusion 33 to help the main body 100 to be pushed in and the connector at the rear end of the main body 100 to be accurately inserted into the chassis space after the main body 100 is pushed in. This is convenient and labor-saving, while ensuring that the connector is not damaged.

[0105] S4: After the main body 100 is fully pushed into the chassis space, continue to rotate the rotating part 1 so that the second inclined surface 511 of the hook 222 slides over the first inclined surface 224 of the connecting groove 51. Through the elastic force of the elastic part 223, the hook 222 is reset and placed on the limiting surface 52, thus completing the fixing of the handle structure to the ear 5 and the installation and fixing of the node module inside the chassis 200.

[0106] Specifically, after the connector at the rear end of the main body 100 and the rear end of the chassis space are connected, the handle part 2 is rotated until the positioning post 215 passes through the positioning through hole 53 to achieve positioning between the handle part 2 and the ear 5. Then, through the elastic force of the elastic part 223, the first inclined surface 224 of the hook 222 slides over the second inclined surface 511 and resets. The limiting surface 52 is placed in the receiving groove 240 to achieve locking and limiting, thus completing the fixing of the handle structure to the ear 5 and the installation and fixing of the node module inside the chassis 200.

[0107] When disassembling the node module:

[0108] S5: Push the slide plate 221 to compress the elastic part 223, and the hook 222 leaves the limiting surface 52 to unlock. At the same time, rotate the rotating part 1 away from the main body 100. The rotating part 1 rotates until the second protrusion 34 abuts against the node support plate 202 and continues to rotate to help pull out the main body 100.

[0109] Specifically, by pushing the slide plate 221 and the hook 222 downward by the toggle block 225, the elastic part 223 is compressed, the hook 222 leaves the limiting surface 52 to unlock, and at the same time the rotating part 1 is rotated away from the main body 100, the handle part 2 leaves the ear 5 and the buckle is reset, the rotating part 1 rotates until the second protrusion 34 abuts against the node support plate 202 and continues to rotate in the same direction, the node support plate 202 generates a reverse force on the second protrusion 34 to help the connector of the main body 100 be pulled out from the rear end of the chassis space.

[0110] S6: Pull the main body 100 outward toward the chassis 200 by using the handle 2 to help pull the main body 100 out of the chassis space.

[0111] With the node module assembly and disassembly method of this application, when installing the node module, the handle part 2 of the handle structure is suspended to facilitate pushing the node module into the chassis space inside the server. When the second protrusion 34 moves to abut against the stop post 203, the rotating part 1 rotates towards the main body 100 until the first protrusion 33 abuts against the stop post 203 and continues to rotate, so as to help the main body 100 and the connector inside the chassis 200 to accurately mate, which is convenient and labor-saving, while ensuring that the connector is not damaged. After the main body 100 is fully pushed into the chassis space, the rotating part 1 is rotated to make the second inclined surface 511 of the hook 222 slide over the first inclined surface 224 of the connecting groove 51. The hook 222 is reset and placed on the limiting surface 52 by the elastic force of the elastic part 223, thus completing the fixing of the handle structure to the ear 5 and the installation and fixing of the node module in the chassis 200. In this way, the insertion and installation of the node module is convenient and quick through the cooperation between the handle structure and the chassis 200. The node module can also be fixed to the chassis 200 through the cooperation between the locking part 22 and the ear 5, which is convenient and quick. When disassembling the node module, the sliding plate 221 is moved to make the elastic part 223 compression, hook 222 leaves the limiting surface 52 to unlock, at the same time rotate the rotating part 1 away from the main body 100 and pull the main body 100 outward to the chassis 200 through the handle part 2. The rotating part 1 rotates until the second protrusion 34 abuts against the node support plate 202 and continues to rotate to help pull out the connector of the main body 100. Finally, the main body 100 is pulled outward to the chassis 200 through the handle part 2 to help pull the main body 100 out of the chassis space. Thus, the unlocking of the node module through the cooperation of the locking part 22 and the box ear 5 is convenient and quick, and the pulling out and disassembling of the node module through the cooperation of the handle structure and the chassis 200 is convenient and quick.

[0112] The foregoing has provided a detailed description of the handle structure, node module, server, and node module assembly / disassembly method provided in this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the protection scope of this application.

The elastic part (223) is inserted into the insertion post (214) and both ends of the elastic part (223) are fixed to the pair of flanges (213) and the slide plate (221) respectively. Multiple grooves (250) are formed on the slide plate (221) and are respectively inserted into multiple guide posts (212).

12. The server according to claim 10, characterized in that, A positioning post (215) is formed on the base (21), and a positioning through hole (53) is formed on the ear (5). A first guide slope (216) and a second guide slope (531) are formed on the positioning post (215) and the positioning through hole (53), respectively. The positioning post (215) passes through the positioning through hole (53) to achieve positioning between the handle (2) and the ear (5).

13. The server according to claim 10, characterized in that, The base (21) has a bent edge (217) and a through groove (218). The slide plate (221) has a lever (225) on its side wall away from the hook (222). The lever (225) is slidably disposed in the through groove (218).

14. A method for assembling and disassembling a node module, characterized in that, Applied to the server as described in claim 10, and comprising the following steps: When installing node modules: The handle part (2) of the handle structure allows the rotating part (1) to be suspended in a rotating position within its rotation angle, and the angle between the rotating part (1) and the main body (100) in the rotating position is 30-60 degrees. The main body (100) is placed on the node support plate (202) and the main body (100) is pushed into the chassis space through the handle (2); When the second protrusion (34) moves to abut against the stop post (203), the rotating part (1) rotates toward the body (100) until the first protrusion (33) abuts against the stop post (203) and continues to rotate to assist the pushing of the body (100); After the main body (100) is fully pushed into the chassis space, the rotating part (1) is rotated to make the second inclined surface (511) of the hook (222) slide over the first inclined surface (224) of the connecting groove (51). Through the elastic force of the elastic part (223), the hook (222) is reset and placed on the limiting surface (52), thus completing the fixing of the handle structure to the box ear (5) and the installation and fixing of the node module in the chassis (200). When disassembling the node module: The sliding plate (221) is moved to compress the elastic part (223), and the hook (222) leaves the limiting surface (52) to unlock. At the same time, the rotating part (1) is rotated away from the main body (100). The rotating part (1) rotates until the second protrusion (34) abuts against the node support plate (202) and continues to rotate to assist the pulling out of the main body (100). The main body (100) is pulled outward from the chassis (200) by the handle (2) to help the main body (100) be pulled out of the chassis space.
