Description

Technical Field

[0001] The present invention relates to the technical field of server devices, and particularly relates to a server chassis assembly and a server. Background Art

[0002] A server is a computer system or software that provides resources, services, or functions for other devices or programs (referred to as clients). It plays a core role in network and computing environments and mainly has functions such as data storage, resource sharing, network services, and computing services, and is widely used in fields such as enterprises, cloud computing, big data, and online games.

[0003] Currently, most device servers are composed of a front panel, a circuit board, a hard disk rack, expansion slots, and cooling fans, forming a box. At present, most server components are fixed by screws during assembly. The installation process requires the use of suitable tools to rotate multiple screws at different positions and angles, which is not only time-consuming and laborious during installation, but also rather cumbersome during maintenance, affecting work efficiency. At the same time, most of the cooling fans in the server are installed at a fixed angle. When cooling the device, the blown air direction is single, and the blown air cannot effectively cover components at various angles in the server device, resulting in poor heat dissipation effect. Therefore, in order to ensure the heat dissipation effect, multiple cooling fans are often installed at different positions, but this will increase the device cost and the practicability is poor.

[0020] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope protected by the present invention.

[0021] Refer to Figures 1-7 As shown, the present invention provides a server chassis assembly, including a chassis bottom plate 1, a front panel 2, two side plates 3, a back plate 4, a cover plate 5 and a controller 12. The front panel 2 is integrally formed vertically at the front end of the chassis bottom plate 1. The two side plates 3 are detachably connected to the chassis bottom plate 1 and the front panel 2 through a clamping structure. A system circuit board 6 is provided on the surface of the chassis bottom plate 1, and the system circuit board 6 is detachably connected to the chassis bottom plate 1 through a first bolt connecting member. A corner of the upper surface of the chassis bottom plate 1 is rotatably connected with an air duct 8, and a blowing assembly is provided in the air duct 8; The back plate 4 is detachably connected to the rear ends of the two side plates 3 through a second bolt connecting member. The cover plate 5 is rotatably connected above a rectangular frame 501. The rectangular frame 501 is detachably installed between the front panel 2 and the back plate 4 through a limiting structure. A driving assembly 9 for driving the air duct 8 to rotate reciprocally is provided on the inner wall of the cover plate 5. Ventilation openings are provided on the surfaces of the front panel 2, the two side plates 3 and the back plate 4. A power supply 7 is fixedly installed on one side of the back plate 4.

[0022] Refer toFigure 2 As shown in FIGS. 6 or 7, the snap - fit structure includes a number of T - shaped first clamping plates 303 fixedly connected to the end of the upper surface of the chassis bottom plate 1. A number of U - shaped clamping plates 301 adapted to be snap - fitted with the T - shaped first clamping plates 303 are fixedly connected to the bottom of the side plate 3. One of the U - shaped clamping plates 301 is vertically and fixedly connected to the front end of the side plate 3. A locking switch for fixing the front - end side plate 3 is provided at the end of the front panel 2. A rubber pad 302 is fixedly connected to the upper surface of each U - shaped clamping plate 301, and one end of the rubber pad 302 close to the opening of the U - shaped clamping plate 301 is designed as an inclined surface. The locking switch includes a cross - shaped sliding groove 304 opened on the front panel 2. A cross - shaped sliding block 305 is slidably connected in the cross - shaped sliding groove 304. A T - shaped second clamping plate 306 adapted to be snap - fitted with the vertical U - shaped clamping plate 301 is fixedly connected to the end face of the cross - shaped sliding block 305. By aligning a number of U - shaped clamping plates 301 below the side plate 3 with a number of T - shaped first clamping plates 303 and pushing, the number of U - shaped clamping plates 301 and the number of T - shaped first clamping plates 303 are inserted into each other. At this time, the vertical U - shaped clamping plate 301 at the end of the side plate 3 abuts against the front panel 2. Then, the cross - shaped sliding block 305 is pushed down to drive the T - shaped second clamping plate 306 to be inserted into the vertical U - shaped clamping plate 301, completing the installation of the side plate 3. The design of the rubber pad 302 enables it to undergo elastic deformation after contacting the T - shaped first clamping plate 303 (similarly applicable to the T - shaped second clamping plate 306, taking the T - shaped first clamping plate 303 as an example here). Through its own elastic force, an interference fit is formed between the T - shaped first clamping plate 303 and the U - shaped clamping plate 301, improving the fitting degree between the two and making the installed structure more firm.

[0023] Refer to Figure 3 As shown in FIGS., the first bolt connecting member includes two bridge plates 601 fixedly connected to the upper surface of the chassis bottom plate 1. Bolt holes 602 are penetrated through both sides of the upper surfaces of the two bridge plates 601. A first bolt 603 is threadedly connected in each bolt hole 602. A through - hole 604 adapted to be inserted with the first bolt 603 is opened on the system circuit board 6. Place the system circuit board 6 on the surfaces of the two bridge plates 601, and then insert the first bolt 603 into the through - hole 604 and the bolt hole 602 and rotate it to complete the installation and fixation of the system circuit board 6. The design of the two bridge plates 601 can lift the system circuit board 6 off the surface of the chassis bottom plate 1, ensuring sufficient air flow and improving the heat dissipation effect.

[0024] Refer to Figures 4-5As shown in the figure, the bottom of the air duct 8 rotates horizontally on the upper surface of the chassis bottom plate 1 through a vertical rotating shaft. The blowing assembly includes a vertical plate 801 fixedly connected inside the air duct 8. A fan blade 802 is rotatably connected to the vertical plate 801. On the other side of the vertical plate 801, a first motor 803 for driving the fan blade 802 to rotate is fixedly installed. The output end of the controller 12 is electrically connected to the input end of the first motor 803. The driving assembly 9 includes a movable ring 901 and a second motor 904. Both ends of the movable ring 901 are fixedly connected with sliding rods 902. Fixed sleeves 903 are sleeved on both sliding rods 902. And both fixed sleeves 903 are connected to the inner wall of the cover plate 5 through connecting rods. In the middle of the bottom surface of the movable ring 901, two abutting rods 907 are fixedly connected. The upper end of the air duct 8 is fixedly connected with an abutting plate 908 located between the two abutting rods 907. The second motor 904 is fixedly connected to the inner surface of the cover plate 5. A semi-gear 906 is fixedly connected to the output shaft of the second motor 904. On both sides of the inner wall of the movable ring 901, racks 905 meshing with the semi-gear 906 are fixedly connected. The cross-sections of the sliding rods 902 and the fixed sleeves 903 are both designed as hexagons. The output end of the controller 12 is electrically connected to the input end of the second motor 904. By controlling the first motor 803 through the controller 12 to drive the fan blade 802 to rotate, the outside cool air is driven to enter the air duct 8 from the rear air holes 10 for transportation and blow towards the surface of the system circuit board 6. At the same time, control the second motor 904 to drive the semi-gear 906 to rotate (the second motor 904 can rotate at a slow speed). When the semi-gear 906 meshes with one side rack 905, drive the movable ring 901 to move to one side, and at the same time drive the two sliding rods 902 to slide in the fixed sleeves 903. Through the hexagonal design of the sliding rods 902 and the fixed sleeves 903, the situation that the movable ring 901 flips during the translation process can be avoided, so that the semi-gear 906 stably meshes with the two side racks 905. As the movable ring 901 moves, the two abutting rods 907 abut against the abutting plate 908 and drive the air duct 8 to rotate horizontally. When the semi-gear 906 rotates to the other side and meshes with the other side rack 905, the air duct 8 can be driven to rotate in the reverse direction, so that the blown cold air is distributed in a fan shape inside the device, improving the heat dissipation effect. A transparent observation window can be provided on the cover plate 5 at the driving assembly 9. At the same time, before the cover plate 5 is closed, the air duct 8 is rotated to a suitable position. When the cover plate 5 is closed, the abutting plate 908 can be effectively located between the two abutting rods 907. Regarding the opening methods of the first motor 803 and the second motor 904, the temperature can be set through a sensor to control the opening, or it can be opened when the device is powered on. The above two control methods are both existing technologies and can be realized by simple programming by those skilled in the art, and will not be elaborated here.

[0025] Refer to Figure 7As shown, the second bolt connector includes bolts two 401 rotatably connected to both ends of the back plate 4. Nuts 402 threadedly adapted to the bolts two 401 are fixedly connected to the rear ends of the two side plates 3. The limiting structure includes grooves 504 opened at the four corners of the rectangular frame 501. Protrusions 505 snap-fitted to the grooves 504 are fixedly connected to both ends of the opposite surfaces of the front panel 2 and the back plate 4. After the two side plates 3 are fixed, the back plate 4 is placed at the rear ends of the two side plates 3, and the bolts two 401 are inserted into the nuts 402 and rotated (here, the bolts two 401 are designed with large heads, so they can be rotated by hand to avoid using tools). As the bolts two 401 continue to rotate, the two protrusions 505 on the surface of the back plate 4 are snap-fitted with the two grooves 504 on the rectangular frame 501, completing the installation and fixation of the back plate 4 and the rectangular frame 501.

[0026] Referring to Figure 6 As shown, the cover plate 5 is rotatably connected to the rectangular frame 501 through a hinge. The controller 12 is fixedly installed on the inner wall of the cover plate 5. Two ear plates 502 are fixedly connected to one side of the inner wall of the rectangular frame 501. Magnets 503 are fixedly connected to both of the two ear plates 502. The magnets 503 are magnetically connected to the iron cover plate 5. The ventilation openings include a number of air holes 10 opened on the front panel 2 and the back plate 4. A number of strip-shaped holes 11 are opened on both of the two side plates 3. When not in maintenance, the cover plate 5 is adsorbed and contacted with the two ear plates 502 by the magnetic force of the magnets 503 for safety protection. A non-woven fabric filter screen (not shown in the figure) is provided at the air holes 10 to prevent external dust from entering the device.

[0027] The present invention also provides a server, including the server chassis assembly described in any one of the above.

[0028] During installation, the system circuit board 6 is installed on the inner bottom of the chassis bottom plate 1 through the first bolt connector. Subsequently, the connector circuit on the front panel 2 is connected to it. Then, several U-shaped clamping plates 301 below the side plate 3 are aligned with several first T-shaped clamping plates 303 and pushed, so that several U-shaped clamping plates 301 are inserted into several first T-shaped clamping plates 303. At this time, the vertically arranged U-shaped clamping plates 301 at the end of the side plate 3 are in contact with the front panel 2. Then, the cross-shaped slider 305 is pushed down to drive the second T-shaped clamping plate 306 to be inserted into the vertically arranged U-shaped clamping plate 301, completing the installation of the side plate 3. Then, the two grooves 504 at the end of the rectangular frame 501 are aligned with the two bumps 505 on the front panel 2 for installation. Subsequently, the two bumps 505 on the back panel 4 are aligned with the two grooves 504 at the other end of the rectangular frame 501 for installation. The connection and fixation between the back panel 4 and the two side plates 3 are completed through the second bolt connector. At the same time, the bump 505 can also fix the rectangular frame 501. Then, the power supply 7 is docked with the interface on the system circuit board 6 (the controller 12 can be connected to the system circuit board 6. By configuring sensors, after detecting high temperature, the controller 12 can control the air outlet and reciprocating swing of the blowing assembly. This is the prior art and will not be elaborated here). When maintenance is required, the entire system circuit board 6 can be exposed by flipping the cover plate 5. When not in maintenance, the cover plate 5 is closed by magnetism, and the opening and closing process is fast and convenient; During heat dissipation, the controller 12 controls the first motor 803 to drive the fan blade 802 to rotate, driving the outside cold air to be blown onto the surface of the system circuit board 6 from the air duct 8. At the same time, the controller 12 controls the second motor 904 to drive the semi-gear 906 to rotate. Through its meshing with both sides of the inner wall of the movable ring 901, the movable ring 901 can be driven to reciprocate horizontally. During the horizontal movement, the two connecting rods 907 are in contact with the connecting plate 908, thereby driving the air duct 8 to rotate horizontally and reciprocally, and further enabling the blown air to cover the entire interior of the device.

[0029] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
