Description

Technical Field

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

[0002] The upper cover of the server chassis is only fixed by a slide structure provided on the server chassis, and only two sides are fixed. However, due to the limited internal space of the server, it is impossible to add fixing components to effectively fix the upper cover panel area.

[0003] Since the upper covers are all made of metal plates, during the operation and maintenance of the server chassis by operators, since the upper cover panel area is not effectively fixed, it is easy for the upper cover to be deformed due to operational errors, which in turn makes it difficult to disassemble and assemble the upper cover.

[0044] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0045] The present application provides a server chassis, including: a main body 1, an upper cover 2 and a connecting component 3; the main body 1 is provided with a rear wall structure 11, the upper cover 2 is slidably connected to the main body 1, the connecting component 3 is connected to a first preset position A of the rear wall structure 11, and is detachably connected to the upper cover 2, so that the positions of the main body 1 and the upper cover 2 are relatively fixed.

[0046] Specifically, the specific structure of the main body 1 is not specifically limited, and can be a standard server chassis structure. In this embodiment, a 1U server chassis can be selected, but it is not limited to a 1U server chassis. The rear wall structure 11 is a supporting structure at the rear end of the server chassis. The rear wall structure 11 can carry the graphics card bracket 4 and fix other required components of the server. The upper cover 2 can be an upper cover 2 of a standard server chassis, which can be adapted to the main body 1. The sliding connection relationship between the upper cover 2 and the main body 1 can be connected through a slideway or a sliding connection through a slide groove, which is not specifically limited.

[0047] The first preset position A can be located at the top area of ​​the rear wall structure 11, or it can be the circumferential position of the rear wall structure 11 close to the inside of the body 1, that is, connected to the side of the rear wall structure 11, and is not specifically limited. It is necessary to ensure that the connecting component 3 does not interfere with the components arranged inside the body 1, and the projection to the upper cover 2 is located in the panel area of ​​the upper cover 2. In this embodiment, the top of the rear wall structure 11 can be understood as the top along the height direction of the server when the server is placed in a normal working state. The connecting component 3 can be a connecting pin or a reinforcing plate connecting plate, and is not specifically limited. It is necessary to ensure that the connecting component 3 can provide a limit for the rear cover to prevent its deformation. The connection method between the connecting component 3 and the rear wall structure 11 can be welding, or it can be a detachable connection achieved by threading. The detachable connection between the connecting component 3 and the upper cover 2 can be achieved by a card slot, or it can be achieved by a magnetic attraction structure, and is not specifically limited.

[0048] In this embodiment, the upper cover 2 panel can be understood as the area covered inside the body 1 after the upper cover 2 is installed on the body 1, that is, the area inside the body 1 is projected onto the upper cover 2 and covers the area of ​​the upper cover 2. During operation, the slideway structure for sliding connection with the body 1 is parallel to the upper cover 2 panel and is located on both sides of the upper cover 2 panel.

[0049] The present application provides a server chassis, which realizes the connection between the upper cover 2 and the rear wall structure 11 of the body 1 through the connection component 3 by setting the connection component 3 at the first preset position A of the rear wall structure 11 of the body 1, and the connection component 3 and the upper cover 2 are detachably connected, so as to realize the connection between the upper cover 2 and the rear wall structure 11 of the body 1 through the connection component 3. Since the first preset position A is located on the rear wall structure 11, its projection to the upper cover 2 is located inside the panel of the upper cover 2, so that the connection component 3 fixes the panel of the upper cover 2, and while the connection component 3 does not affect the arrangement of other components of the server chassis, the deformation of the upper cover 2 is limited to prevent the deformation of the panel of the upper cover 2 caused by operating errors due to the lack of effective fixation of the remaining areas of the upper cover 2 except for the two sides. The problem of difficulty in disassembly and assembly caused by deformation of the upper cover 2 is effectively reduced.

[0050] In some embodiments, the main body 1 includes: a graphics card bracket 4, the graphics card bracket 4 is connected to the rear wall structure 11, the graphics card bracket 4 has a first accommodating space C and a second accommodating space D, and the first preset position A is at the top of the rear wall structure 11 and is located between the first accommodating space C and the second accommodating space D.

[0051] Specifically, the connection between the graphics card bracket 4 and the rear wall structure 11 can be by screw connection or by card slot connection, which is not specifically limited. The graphics card bracket 4 can be composed of a plate, and its first accommodating space C and the second accommodating space D are arranged side by side along the extension direction of the rear wall structure 11, and the two can be enclosed by the plate. The first accommodating space C and the second accommodating space D are used to accommodate graphics cards. Since the layout position of the graphics card is close to the middle position of the upper cover 2 along the extension direction of the rear wall structure 11, the layout position of the graphics card is the layout position of a conventional server chassis, and the reasons for its layout are not repeated. Correspondingly, the position between the first accommodating space C and the second accommodating space D is relatively close to the middle part of the upper cover 2 along the extension direction of the rear wall structure 11. When the graphics card is set in the first accommodating space C and the second accommodating space D of the graphics card bracket 4, the graphics card will be mounted on the top of the rear wall structure 11, so that the rear wall structure 11 shares the weight of the graphics card for the graphics card bracket 4. Generally speaking, no other components will be set at the position of the top of the rear wall structure 11 between the first accommodating space C and the second accommodating space D. Setting the first preset position A here can avoid interference between the connecting component 3 and the graphics card so as to connect the panel of the upper cover 2.

[0052] In some embodiments, the connecting component 3 is a columnar structure 33, and the connecting component 3 has a first end and a second end that are relatively set. The first end is fixedly connected to the first preset position A, and the second end is connected to the second preset position B of the upper cover 2, and the second preset position B corresponds to the first preset position A.

[0053] Specifically, the connecting component 3 can be a cylindrical structure 33 or a square columnar structure 33, and its specific shape is not limited. The first end of the connecting component 3 can be connected to the first position of the rear wall structure 11 by threaded connection or by welding. The connection between the second end and the upper cover 2 can be by threaded connection or by a magnetic component to achieve a detachable connection, and it is not specifically limited. The correspondence between the second preset position B and the first preset position A can be understood as the projection of the second preset position B to the first preset position A covers the first preset position A. The connecting component 3 is a columnar structure 33, which can provide a sufficiently stable connection between the upper cover 2 and the rear wall structure 11. At the same time, the connection of the connecting component 3 to the second preset position B, that is, the middle position of the upper cover 2 along the extension direction of the rear wall close to the rear wall structure end is fixed. Since there are fixed structures on both sides of the upper cover 2 when the upper cover 2 is connected to the main body 1, when the operator makes an operation error, the maximum deformation area of ​​the upper cover 2 is located in the middle part of the upper cover 2 along the extension direction of the rear wall structure 11. The connecting component 3 is used to connect the first preset position A of the rear wall structure 11 and the second preset position B of the upper cover 2, so that the connecting component 3 can fix the middle position of the upper cover 2 along the extension direction of the rear wall close to the rear wall structure end, effectively reducing the deformation degree of the maximum deformation area of ​​the upper cover 2.

[0054] In some embodiments, the connecting component 3 also includes: a first connecting component 313 and a second connecting component 323; the first connecting component 313 is arranged at the first end, and the first connecting component 313 is used to connect to the first preset position A of the rear wall structure 11; the second connecting component 323 is arranged at the second end, and the second connecting component 323 is used to connect to the second preset position B of the upper cover 2.

[0055] Specifically, the first connecting member 313 and the second connecting member 323 may be a locking structure, and the first end and the second end of the connecting member 3 are connected to the first preset position A of the rear wall structure 11 and the second preset position B of the upper cover 2 respectively through the locking structure and the connection. The first connecting member 313 and the second connecting part may also be a threaded structure, and threaded holes are provided on the top of the rear wall structure 11 and the panel of the upper cover 2 at the same time, and the first end and the second end of the connecting member 3 are connected to the first preset position A of the rear wall structure 11 and the second preset position B of the upper cover 2 respectively through the threaded structure and the threaded holes, and the connection method thereof is not specifically limited. The first connecting member 313 and the second connecting member 323 can enable the connecting member 3 to provide a stable connection for the rear wall structure 11 and the upper cover 2, and can increase the convenience of the installation process of the connecting member 3. In this embodiment, the first connecting member 313 may adopt a riveting structure to achieve the connection with the first preset position A of the rear wall structure 11.

[0056] In some embodiments, the upper cover 2 includes: a clamping structure 21, the clamping structure 21 is disposed at a second preset position B, and the second connecting component 323 is connected to the clamping structure 21 to relatively fix the positions of the body 1 and the upper cover 2.

[0057] Specifically, the clamping structure 21 can be a mortise and tenon structure, or can be realized by the cooperation of a slideway structure and a component, and is not specifically limited. The second connecting component 323 is clamped by the clamping structure 21 to achieve the fixing of the connecting component 3 to the upper cover 2. The use of the clamping structure 21 can make the installation and removal process of the upper cover 2 simpler and faster, while providing a stable connection and reducing costs. The clamping structure 21 can achieve a lossless connection, that is, repeated disassembly and assembly under normal operation will not cause damage to the upper cover 2 and the connecting component 3, thereby extending the service life of the components.

[0058] In some embodiments, the clamping structure 21 includes a clamping structure 211 and a strip-shaped through-slot structure 212 connected to the clamping structure 211 .

[0059] Specifically, the second connection part 323 slides in the strip-shaped through-slot structure 212, and the extension direction of the strip-shaped through-slot structure 212 can be the sliding direction when the upper cover 2 is connected to the body 1. The length of the strip-shaped through-slot structure 212 is the travel of the sliding connection between the upper cover 2 and the body 1. It can be understood that when the upper cover 2 completely covers the body 1, the second connection part 323 is at one end of the strip-shaped through-slot structure, and when the upper cover 2 and the body 1 are separable, the second connection part 323 is at the other end of the strip-shaped through-slot structure. In this way, the upper cover 2 can be quickly positioned through the strip-shaped through-slot structure 212, and at the same time, it can prevent the upper cover 2 from being damaged after being disassembled multiple times due to the interference between the upper cover 2 and the second connection part 323 during the installation process of the upper cover 2.

[0060] Since the upper cover 2 slides in the direction close to the rear wall structure 11 during the installation of the upper cover 2 on the body 1, the clamping structure 211 is arranged at one end of the strip through-slot structure close to the rear wall structure 11. The clamping structure 211 can clamp the second connecting component 323 so that the connecting component 3 fixes the upper cover 2. The clamping structure 211 can be a clamping hole, or a clamping space with an opening on one side, the direction of the opening is toward the end of the strip through-slot structure away from the rear wall structure 11, the second connecting component 323 slides into the clamping space through the strip through-slot structure, and the clamping space provides a limit perpendicular to the panel direction of the upper cover 2 for the second connecting component 323. The specific form of the clamping structure 211 can be selected according to the first connecting component 313, and is not specifically limited. In this embodiment, the second connecting component 323 can adopt a holding block, and correspondingly, the holding structure 211 can adopt a holding hole connected to the strip-shaped through-groove structure 212. The holding block can slide into the holding hole through the strip-shaped through-groove structure 212 and be held in the holding block, so that the connecting component 3 fixes the upper cover 2.

[0061] In some embodiments, the guide surface of the holding structure 211 sinks toward the direction close to the rear wall structure 11 to form an accommodating space E, and the accommodating space E can hold and accommodate the second connecting component 323.

[0062] In this embodiment, since the connecting component 3 is located inside the body 1, when the clamping structure 211 clamps the second connecting component 323, part of the second connecting component 323 will protrude from the side of the upper cover 2 away from the inside of the body 1, which will increase the ineffective volume of the server chassis. The guide surface of the clamping structure 211 sinks toward the direction close to the rear wall structure 11, which can be understood as the part of the upper cover 2 where the clamping structure 211 is set is recessed into the inside of the body 1, and the recess constitutes the accommodation space E. The part of the second connecting component 323 protruding from the upper cover 2 is located in the accommodation space E, which effectively reduces the ineffective volume of the server chassis. In this embodiment, the clamping structure 211 is a clamping hole, and the hole surface of the clamping hole on one side away from the inside of the body 1 serves as a guide surface, so that the guide surface and the inner wall of the strip-shaped through-slot structure 212 constitute the accommodation space E.

[0063] In some embodiments, a guide transition curved surface structure 213 is disposed at a position where the clamping structure 211 communicates with the strip-shaped through-slot structure 212 .

[0064] Specifically, the guide transition curved surface structure 213 may be a transition curved surface at the connection point between the clamping structure 211 and the strip-shaped through-slot structure 212, so that the first connecting component 313 can slide more smoothly from the strip-shaped through-slot structure 212 into the clamping structure 211, or slide from the clamping structure 211 into the strip-shaped through-slot structure 212, so as to prevent the first connecting component 313 from colliding and causing structural damage when sliding back and forth between the strip-shaped through-slot structure 212 and the clamping structure 211. In this embodiment, the guide transition curved surface structure 213 may be two opposite curved surfaces arranged at the connection point between the clamping structure 211 and the strip-shaped through-slot structure 212, the curved surfaces extending toward the inside of the body 1, and the curved surface portion facing the end of the strip-shaped through-slot structure 212 away from the rear wall structure 11.

[0065] In some embodiments, the second connecting component 323 includes: a first boss structure 321, a cylindrical transition structure 322 and a second boss structure 323; the first boss structure 321 has a first connecting surface and a second connecting surface with an area larger than the first connecting surface, and the second connecting surface is fit-connected to the end surface of the second end; the first end surface of the cylindrical transition structure 322 is fit-connected to the first connecting surface; the second boss structure 323 has a third connecting surface and a fourth connecting surface with an area larger than the third connecting surface, and the third connecting surface is fit-connected to the second end surface of the cylindrical transition structure 322.

[0066] Specifically, the first boss structure 321, the cylindrical transition structure 322 and the second boss structure 323 can be integrally formed or connected by screws, and their specific connection method is not limited. The area of ​​the second connection surface and the fourth connection surface of the first boss structure 321 and the second boss structure 323 is smaller than the groove surface of the strip-shaped through-groove structure 212, but larger than the hole area of ​​the holding hole of the holding structure 211. The cross-sectional area of ​​the first connection surface and the second connection surface of the first boss structure 321 and the second boss structure 323 and the cylindrical transition structure 322 perpendicular to the length direction is smaller than the area of ​​the holding hole, so that the second connecting component 323 can be inserted into the strip-shaped through-groove structure 212, and the cylindrical transition structure 322 is located in the holding structure 211. With such a configuration, when the panel of the upper cover 2 is deformed during the clamping process of the first connection component 313, an allowable elastic deformation can be performed between the first boss structure 321 and the second boss structure 323, so as to prevent the second connection component 323 from causing the second preset position B of the upper cover 2 to interact with the second connection component when restricting the upper cover 2, thereby causing partial damage to the upper cover 2. At the same time, when the panel of the upper cover 2 is elastically deformed to the limit, it contacts the inclined surfaces of the first boss and the second boss, effectively reducing the damage to the clamping structure 211.

[0067] In some embodiments, the graphics card bracket 4 is provided with a positioning hole 41 between the first accommodating space C and the second accommodating space D. When the graphics card bracket 4 is connected to the rear wall structure 11 , the connecting component 3 can be inserted into the positioning hole 41 .

[0068] Specifically, the graphics card bracket 4 is located between the first accommodating space C and the second accommodating space D and is provided with a positioning through hole 41, that is, the projection position of the first preset position A and the second preset position B to the graphics card bracket 4 is the position of the positioning through hole 41. During the assembly process, the first preset position A is first determined according to the installation slot and the connecting hole of the graphics card bracket 4, and the connecting component 3 is set at the first preset position A, and the graphics card bracket 4 is passed through the positioning through hole 41 on the connecting component 3 to achieve rapid positioning of the graphics card bracket 4 and a certain degree of limitation, so as to facilitate the connection between the graphics card and the rear wall structure 11 of the main body 1 and other positions of the main body 1.

[0069] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
