Description

Technical Field

[0001] This invention relates to the field of server technology, and more specifically to a modular and expandable rack server and its control method. Background Technology

[0002] A rack server is a server device installed in a standard server rack. It typically includes a chassis and functional modules such as a motherboard, power supply, hard drives, heat dissipation components, and communication interface modules housed within the chassis. Due to their compact structure and ease of centralized deployment and maintenance, rack servers are widely used in data centers, enterprise server rooms, and edge computing nodes.

[0003] Existing rack-mount servers typically use fixed-size chassis structures, with the internal installation space determined at the factory. However, in actual use, the required number and types of server functional modules vary across different application scenarios. For example, when the chassis design size is small, the number of expansion modules that can be installed is limited, making it difficult to meet subsequent expansion needs; while when the chassis design size is large, if some functional modules are not installed or are not needed temporarily, the internal space of the chassis is prone to being idle, resulting in a large overall space occupation by the equipment and reduced rack space utilization. In other words, the chassis structure of existing rack-mount servers usually cannot be adjusted, expanded, or contracted according to actual usage needs, exhibiting poor adaptability.

[0004] Furthermore, rack-mount servers require continuous airflow for heat dissipation during long-term operation. To reduce dust entering the chassis, filters are typically installed at the air intake. These filters easily accumulate dust over time, and if not cleaned promptly, they can affect airflow efficiency and heat dissipation, thus impacting server stability. Cleaning existing filters usually relies on manual disassembly or wiping, which is not only cumbersome but also causes dust to easily scatter around the chassis or inside the rack, polluting the surrounding environment. Subsequent dust collection and disposal are also inconvenient. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention aims to provide a modular and scalable rack server and its control method. To solve these problems, this invention employs the following technical solution: A modular and expandable rack server includes a chassis with an organic cavity. The cavity is connected to the top wall of the chassis via a communication port. A foldable expansion component is connected to the top wall of the chassis, and a component connection component is connected to the foldable expansion component. A filter and a movable cleaning component are connected to the side wall of the chassis, and a recycling component is connected to the movable cleaning component.

[0006] Optionally, the foldable expansion assembly includes an expansion top plate, a sealing plate, and three side plate assemblies. The sealing plate is rotatably connected to the expansion top plate. The side plate assemblies include expansion side plates and slide bars. The expansion side plates are rotatably connected to the expansion top plate, and the slide bars are rotatably connected to the expansion side plates and slidably connected to the top wall of the chassis.

[0007] Optionally, the component connection assembly includes a movable support plate, which is slidably connected to the extension top plate. A damping shaft is rotatably connected to the movable support plate. A mounting plate and an interleaved helical gear I are fixedly connected to the damping shaft. An extension mounting part is connected to the bottom wall of the mounting plate. An interleaved helical gear II is rotatably connected to the movable support plate. A spur gear is fixedly connected to the interleaved helical gear II. A rack is fixedly connected to the extension top plate.

[0008] Optionally, the movable cleaning component includes a cleaning frame with brush bristles connected to it. A transmission plate is rotatably connected to the cleaning frame via an automatic return shaft. Two flexible limiting plates are fixed to the cleaning frame, and the flexible limiting plates abut against the transmission plate.

[0009] Optionally, the recycling assembly includes a recycling bin, a pressing plate, and a second inclined plate. The recycling bin is detachably connected to the cleaning rack. The pressing plate is slidably connected to the outer wall of the chassis. The pressing plate is connected to the outer wall of the chassis through an elastic element. An inclined plate is fixedly connected to the pressing plate. The second inclined plate is fixedly connected to the cleaning rack. Two telescopic plates are slidably connected to the pressing plate. The telescopic plates are connected to the pressing plate through an elastic element. The telescopic plates are provided with inclined surfaces. The recycling bin is provided with two inclined surfaces.

[0010] Optionally, the sealing plate is provided with a locking part one, and the top wall of the chassis is provided with a locking part two, and the locking part one and the locking part two are adapted to each other.

[0011] Optionally, the top wall of the extended top plate is provided with a handle groove.

[0012] Optionally, the movable support plate has a through hole, and the damping shaft is rotatably connected to the inner wall of the through hole.

[0013] Optionally, the chassis, expansion top plate, expansion side plate, and sealing plate are made of the same material.

[0014] A method for operating a modular and scalable rack server, based on the aforementioned modular and scalable rack server, includes the following steps: When no expansion module is needed, the foldable expansion component is folded. When expansion modules are needed, unfold the foldable expansion components and connect the expansion modules to be installed with the component connection components. When the filter needs cleaning, the movable cleaning component cleans the filter, and the recycling component collects any debris that falls onto the filter.

[0015] The present invention has the following beneficial effects: This invention provides a foldable expansion assembly consisting of an expansion top plate, expansion side plates, sliding strips, and a sealing plate, which allows the server to remain folded when no expansion module is needed, thereby reducing the overall space occupied and improving the utilization rate of the server rack space. When expansion modules are needed, the expansion side panels can be unfolded by lifting the expansion top plate to form a cavity to accommodate the expansion modules, so that the chassis structure can be unfolded or retracted according to actual usage needs, taking into account both expansion capability and space occupation. Meanwhile, the present invention utilizes the cooperation between the movable support plate, the mounting plate, the damping shaft, the first intersecting shaft helical gear, the second intersecting shaft helical gear, the spur gear, and the rack to enable the mounting plate to automatically rotate to a position that facilitates the connection of the expansion module when the movable support plate is pulled out, and to drive the expansion module into the expansion cavity when the movable support plate is reset, thereby improving the convenience of installation and storage of the expansion module.

[0016] Furthermore, this invention utilizes the linkage between the mounting plate, transmission plate, automatic return shaft, flexible limiting plate, cleaning rack, and brush bristles to simultaneously drive the brush bristles to clean the filter screen during the installation and reset of the expansion module, eliminating the need for additional filter screen disassembly or separate manual wiping. The swept-down dust and impurities can fall into a collection bin that moves with the cleaning rack for centralized collection, preventing contamination of the surrounding area of ​​the chassis or the interior of the cabinet. The dust and impurities in the collection bin are compressed by the cooperation of the pressing plate, elastic element one, inclined plate one, inclined plate two, telescopic plate, and elastic element two, reducing the space occupied by dust and preventing dust overflow, thereby improving the convenience of server maintenance, heat dissipation stability, and cleanliness of use.

[0023] The core function of a rack-mount server is to provide centralized general-purpose computing power, massive storage, reliable network connectivity, and communication functions for internet platforms in a standardized, high-density form, serving as the physical device to host all software systems and process industrial data.

Some modules within chassis 1 can be 3D stacked and packaged on the hybrid substrate.

[0024] like Figures 2-8 As shown, a modular and expandable rack server includes a chassis 1 with an organic cavity. The cavity is connected to the top wall of the chassis 1 via a connecting port 2.

[0027] The expansion top plate 3, expansion side plate 4, and sealing plate 19 are used together to form a foldable and unfoldable expansion space. The slide bar 5 is used to guide the expansion side plate 4 to slide relative to the top wall of the chassis 1 so as to facilitate the switching of the foldable expansion assembly between the folded state and the unfolded state.

[0028] In a preferred embodiment, the component connecting assembly includes a movable support plate 6, which is slidably connected to the extension top plate 3.

A spur gear 11 is fixedly connected to the second cross-axis helical gear 10. A rack 12 is fixedly connected to the extension top plate 3.

[0029] The movable support plate 6 is used to extend or retract the mounting plate 7. The mounting plate 7 is used to carry and connect the expansion module to be installed. The damping shaft 8 is used to support the rotation of the mounting plate 7. The rack 12, spur gear 11, cross-axis helical gear 2 10 and cross-axis helical gear 1 9 are used to drive the mounting plate 7 to flip when the movable support plate 6 moves, so as to facilitate the installation and storage of the expansion module.

[0030] Regarding the implementation of the movable cleaning component, the movable cleaning component includes a cleaning frame 14, on which bristles 15 are connected. A transmission plate 17 is rotatably connected to the cleaning frame 14 via an automatic return shaft 16. Two flexible limiting plates 18 are fixedly connected to the cleaning frame 14, and the flexible limiting plates 18 and the transmission plate 17 abut against each other.

[0031] The cleaning frame 14 can move horizontally along the outer wall of the housing 1. The cleaning frame 14 is used to drive the brush bristles 15 to move relative to the filter screen 13. The brush bristles 15 and the filter screen 13 abut against each other. The brush bristles 15 are used to clean the dust and impurities on the filter screen 13. The transmission plate 17 is used to receive the push of the mounting plate 7 and drive the cleaning frame 14 to move. The automatic return shaft 16 and the flexible limit plate 18 are used to make the transmission plate 17 rotate to avoid and automatically reset after being subjected to force.

[0032] Furthermore, the recycling assembly includes a recycling bin 20, a pressing plate 21, and a second inclined plate 24. The recycling bin 20 is detachably connected to the cleaning rack 14. The pressing plate 21 is slidably connected to the outer wall of the housing 1. The pressing plate 21 is connected to the outer wall of the housing 1 through an elastic element 22.

[0034] Optionally, the sealing plate 19 is provided with a locking part one, and the top wall of the chassis 1 is provided with a locking part two, and the locking part one and the locking part two are adapted to each other. The structure of the locking part one and the locking part two can refer to the existing technology design, and is not limited here.

[0035] The top wall of the extended top plate 3 is provided with a handle groove.

[0036] The movable support plate 6 has a through hole, and the damping shaft 8 is rotatably connected to the inner wall of the through hole. The through hole is used to accommodate the damping shaft 8 and the mounting plate 7.

[0037] Regarding the optional material settings, the chassis 1, expansion top plate 3, expansion side plate 4, and sealing plate 19 are all made of the same material. The material can be galvanized steel sheet, with an anti-static coating applied to the surface during manufacturing.

[0038] Note that the electrical connection structure of this application is implemented using existing technology, and will not be specifically described or limited here.

[0039] like Figure 1 As shown, a method for operating a modular and scalable rack server, based on the aforementioned modular and scalable rack server, includes the following steps: When no expansion module is needed, the foldable expansion component is folded. When expansion modules are needed, unfold the foldable expansion components and connect the expansion modules to be installed with the component connection components. When the filter screen 13 needs to be cleaned, the filter screen 13 is cleaned using the movable cleaning component, and the recycling component is used to collect the impurities that fall onto the filter screen 13.

[0040] Implementation process: When no expansion modules are needed, such as Figure 1 As shown, the foldable expansion assembly is in a folded state, that is, the expansion top plate 3, the sealing plate 19 and the three expansion side plates 4 are nearly parallel to each other, and the sealing plate 19 is located above the expansion top plate 3. This arrangement can save server space.

[0041] When expansion modules are needed, unfold the foldable expansion components and connect the expansion modules to be installed with the component connection components. The specific operation is as follows: In the initial state, such as Figure 6 As shown, inclined plate 24 and inclined plate 23 abut together, elastic element 22 is stretched, inclined plate 23 and two telescopic plates 25 extend into the recycling bin 20, telescopic plates 25 abut against the inner wall of the recycling bin 20, and two elastic elements 26 are compressed.

[0042] A finger can be inserted into the handle groove to lift the expansion top plate 3 upwards, causing the three sliders 5 to slide onto the expansion top plate 3. This causes the three expansion side plates 4 to become vertical and remain in this position (because there is a certain damping force at the sliding connection between the sliders 5 and the chassis 1). The expansion top plate 3 and the three expansion side plates 4 form a cavity to accommodate the module to be installed. Pull out the movable tray 6. When the mounting plate 7 moves to the side of the chassis 1, the transmission teeth on the spur gear 11 and the rack 12 mesh. The rack 12 drives the spur gear 11 to rotate. The spur gear 11 drives the staggered shaft helical gear 2 10, staggered shaft helical gear 1 9, damping shaft 8, and mounting plate 7 to rotate. The mounting plate 7 rotates about 180 degrees (the mounting plate 7 has moved to the side of the chassis 1 and will not touch the chassis 1). This causes the expansion mounting part on the mounting plate 7 to face upwards, so that the user can easily see the expansion mounting part and quickly connect the expansion module to be installed.

[0043] When the mounting plate 7 rotates approximately 180 degrees, it pushes the transmission plate 17 to move horizontally. Under the resistance of the two flexible limit plates 18 and the resistance of the automatic return shaft 16, the transmission plate 17 will drive the cleaning frame 14 to move horizontally. The transmission plate 17 will not rotate at an excessive angle. After the inclined plate 24 moves, it disengages and abuts against the inclined plate 23. The inclined plate 23 moves upward under the contraction force of the elastic element 22 (because the recycling box 20 is in horizontal displacement, the telescopic plate 25 will slide on the pressing plate 21). The telescopic plate 25 moves upward with the pressing plate 21. Both the pressing plate 21 and the telescopic plate 25 move above the recycling box 20 to prevent obstruction of the horizontal movement of the recycling box 20. When the recycling box 20 moves horizontally, it will drive the brush bristles 15 to clean the dust and impurities of the filter screen 13. The recycling box 20 abuts against the outer wall of the casing 1. The dust and impurities fall into the recycling box 20 for collection to prevent pollution of the surrounding environment. When the cleaning rack 14 moves to the right limit position, the transmission plate 17 is pushed by the mounting plate 7 to rotate around the automatic return shaft 16. After the mounting plate 7 disengages from the transmission plate 17, the transmission plate 17 reverses and resets under the automatic return function of the automatic return shaft 16 and the elastic force of the flexible limit plate 18.

[0044] After the expansion module to be installed and the expansion mounting part are connected, push the movable tray 6 into the expansion top plate 3 to reset it. The rack 12 drives the spur gear 11 to reverse. After the mounting plate 7 rotates in the opposite direction by about 180 degrees, the spur gear 11 disengages from the transmission teeth on the rack 12. The expansion module to be installed enters the cavity formed by the expansion top plate 3 and the three expansion side plates 4. Then rotate the sealing plate 19 to the vertical position. The locking part one on the sealing plate 19 and the locking part two on the chassis 1 are locked together to protect the expansion module.

[0045] When the mounting plate 7 rotates in the opposite direction by about 180 degrees, the mounting plate 7 will push the transmission plate 17 in the opposite direction. The transmission plate 17 will drive the cleaning frame 14 to move in the opposite direction. The brush bristles 15 will clean the dust and impurities of the filter screen 13 again. Then, the inclined plate 24 will push the inclined plate 1 23 to move down. The inclined surfaces on the two telescopic plates 25 will abut against the inclined surfaces on the recycling box 20, so that the two telescopic plates 25 will overcome the elastic force of the elastic element 26 and retract into the pressing plate 21. The telescopic plates 25 will also enter the recycling box 20 and abut against the inner wall of the recycling box 20. The pressing plate 21 and the two telescopic plates 25 will compress the dust and impurities in the recycling box 20, which will not only reduce the space occupied by dust and impurities in the recycling box 20, but also prevent dust from overflowing.

[0046] It is worth noting that the expansion module can be one or more of the following: microcontrollers such as processor chips, hard drives, heat sinks, etc.

[0047] The technical effects of this invention are as follows: This invention provides a foldable expansion assembly consisting of an expansion top plate 3, expansion side plates 4, sliding strips 5, and a sealing plate 19, installed on the top wall of the chassis 1. When no expansion module is needed, the expansion top plate 3, sealing plate 19, and three expansion side plates 4 can be brought close to each other and folded, thereby reducing the overall external space occupied by the server. When an expansion module is needed, the expansion top plate 3 can be lifted, and the three sliding strips 5 slide relative to the expansion top plate 3, causing the three expansion side plates 4 to unfold, so that the expansion top plate 3 and the three expansion side plates 4 form a cavity to accommodate the module to be installed. This allows the rack server to switch between the folded and unfolded states according to actual usage needs, solving the problem that existing fixed-size chassis cannot balance expansion capability and space occupation.

[0048] Furthermore, through the cooperation between the movable tray 6, mounting plate 7, damping shaft 8, intersecting helical gear 19, intersecting helical gear 20, spur gear 11, and rack 12, when the movable tray 6 is pulled out to the side of the chassis 1, the transmission teeth on the spur gear 11 and rack 12 mesh at the appropriate time. The rack 12 can drive the mounting plate 7 to rotate about 180 degrees through the spur gear 11, intersecting helical gear 20, intersecting helical gear 19, and damping shaft 8, so that the expansion mounting part on the mounting plate 7 faces upward, making it easier for the user to observe and connect the expansion module to be installed. After the connection is completed, the movable tray 6 is pushed back into the expansion top plate 3. With the cooperation of the sealing plate 19, the mounting plate 7 can rotate in the opposite direction and drive the expansion module into the cavity formed by the expansion top plate 3 and the three expansion side plates 4, thereby improving the convenience of installation, connection, and storage of the expansion module.

[0049] Furthermore, through the linkage structure between the mounting plate 7, transmission plate 17, automatic return shaft 16, flexible limit plate 18, cleaning frame 14, and brush 15, the mounting plate 7 can push the transmission plate 17 to move horizontally during its rotation of approximately 180 degrees. The transmission plate 17 drives the cleaning frame 14 to move, and the brush 15 on the cleaning frame 14 can clean the filter screen 13. When the movable support plate 6 is reset and the mounting plate 7 rotates in the reverse direction, the mounting plate 7 can push the transmission plate 17 in the reverse direction, causing the cleaning frame 14 to move in the reverse direction and drive the brush 15 to clean the filter screen 13 again. Thus, without the need for additional disassembly of the filter screen 13 or separate manual wiping, the cleaning of the filter screen 13 can be completed in a linked manner during the installation and reset of the expansion module, improving maintenance convenience and helping to maintain air intake efficiency and server heat dissipation stability.

[0050] This invention also includes a recycling bin 20 installed on the cleaning rack 14, which moves with the cleaning rack 14. Dust and impurities swept off the filter screen 13 by the brush bristles 15 can fall directly into the recycling bin 20 for centralized collection, preventing dust from scattering around the chassis 1 or inside the cabinet during cleaning, thus reducing environmental pollution and facilitating subsequent unified disposal of dust and impurities. Through the cooperation of the pressing plate 21, elastic element 22, inclined plate 23, inclined plate 24, telescopic plate 25, and elastic element 26, the cleaning rack 14 moves smoothly during its movement. The inclined plate 24 can release or restore the contact state with the inclined plate 23, allowing the pressing plate 21 and the telescopic plate 25 to move up or down relative to the recycling box 20. When cleaning is completed and the box is reset, the inclined plate 24 pushes the inclined plate 23 down, and the two telescopic plates 25, under the action of the inclined surface of the recycling box 20, overcome the elastic force of the elastic element 26 and retract into the pressing plate 21, and enter the recycling box 20 to compress dust and impurities, thereby reducing the space occupied by dust and impurities in the recycling box 20, reducing the possibility of dust overflowing again, and improving the holding capacity of the recycling box 20.
