Description

Technical Field

[0001] This application belongs to the field of data center cabinet technology, and more specifically, relates to a segmented cabinet bottom structure and a cabinet assembly applied to data centers. Background Technology

[0002] Data centers play a vital role in various fields, including work, life, entertainment, finance, and technology. A server rack in a data center is a standardized, structured rack specifically designed for the installation, integration, protection, and management of the data center's core IT equipment, power supply equipment, and network equipment.

[0003] The bottom panel of the server rack is a crucial sealing structure, serving the following functions: First, it effectively isolates the cold and hot aisles, preventing hot air from flowing back into the cold aisle due to pressure differences, thus avoiding wasted cooling capacity. Second, it blocks dust and debris from entering the rack through the open ports, preventing foreign objects from accumulating on server fans or circuit boards, which can impair heat dissipation and even cause short circuits. Third, it prevents accidental insertion of fingers or small objects into the rack, protecting against accidental contact with live power terminals or high-speed fans, providing a degree of safety. Fourth, the bottom panel also provides access for cables, serving as a vital pathway for power connection to the rack.

[0004] Existing rack bottom panels are mostly designed as a single piece, requiring different sizes of bottom panels to be manufactured for racks of different depths, resulting in high manufacturing and usage costs. Furthermore, the large area of ​​the bottom panel makes assembly with the rack frame more difficult, requiring repeated adjustments to ensure proper positioning and impacting assembly efficiency. Utility Model Content

[0005] The purpose of this application is to provide a segmented cabinet bottom structure and a cabinet assembly for use in data centers, aiming to solve the problems of poor flexibility in the use of existing cabinet bottom panels and high assembly difficulty with the cabinet frame.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows: In a first aspect, embodiments of this application provide a segmented cabinet bottom structure, including: The bottom frame has a gap in the middle; Multiple bottom sealing plates are sequentially joined together in the front-to-back direction. After the bottom sealing plates are joined together, they form a sealing structure that covers the empty area in the middle of the bottom frame. The outer edge of each bottom sealing plate overlaps and is fixed to the inner edge of the adjacent bottom frame. The bottom sealing plate located at the front or rear end has multiple inlet openings, and the inlet openings are detachably covered with opening seals.

[0007] The existing bottom panel is a one-piece component. Depending on the depth of the rack, different bottom panels of appropriate sizes need to be manufactured, which negatively impacts the control of manufacturing and usage costs. In addition, due to the large size of the bottom panel, manufacturing errors are difficult to control, resulting in assembly errors between it and the rack frame that are also difficult to manage (i.e., the assembly positions of the two are difficult to align). The position of the bottom panel needs to be repeatedly adjusted during assembly, which increases the assembly difficulty and affects assembly efficiency.

[0008] The solution shown in this application, compared with the prior art, uses multiple bottom sealing plates joined together in the front-to-back direction to form a cover structure. The cover structure is a segmented design, achieving the same sealing function as traditional bottom sealing plates. Depending on the different cabinet depths, different numbers of bottom frames can be selected for splicing, eliminating the need to manufacture bottom sealing plates separately for different cabinets. The bottom sealing plate of this application offers greater design and usage flexibility, effectively reducing manufacturing and usage costs. Furthermore, due to the joint design of multiple bottom sealing plates, the size of each individual bottom sealing plate is smaller, resulting in less manufacturing error and reduced cumulative assembly errors. Therefore, when assembling a single bottom sealing plate with the bottom frame, the connection position is easier to align, eliminating the need for repeated adjustments during assembly. This reduces the assembly difficulty of the bottom sealing plate, effectively shortening the assembly time between the bottom sealing plate and the bottom frame, and improving assembly efficiency.

[0009] In conjunction with the first aspect, in one possible implementation, the mating edge of the bottom sealing plate is bent downward to form a mating flange, which can abut against the mating flanges on the adjacent bottom sealing plates.

[0010] In conjunction with the first aspect, in one possible implementation, the cable inlet includes a first cable inlet hole and a second cable inlet hole, wherein the first cable inlet hole is a rectangular hole and the second cable inlet hole is a circular hole; The opening sealing component includes an inlet sealing plate for sealing the first inlet hole and a blind hole sealing ring for sealing the corresponding blind hole of the second inlet hole.

[0011] In some embodiments, the edge of the inlet sealing plate is overlapped and fixed with the edge of the first inlet hole, and the edge of the blind hole sealing ring is snapped and fixed with the edge of the second inlet hole.

[0012] In some embodiments, the edge of the first inlet hole is provided with a cable protection element.

[0013] In some embodiments, the first inlet hole is provided, and the first inlet hole extends in the left-right direction; The second inlet hole is provided in multiple ways, and the multiple second inlet holes are distributed at intervals along the left and right direction; Each of the second inlet holes is located in front of the first inlet hole, or each of the second inlet holes is located behind the first inlet hole.

[0014] In some embodiments, the front and rear edges of the first inlet hole extend downward to form a protective flange, which is the cable protection component.

[0015] In some embodiments, the inlet sealing plate is a rectangular plate that conforms to the shape of the first inlet hole. The left and right ends of the inlet sealing plate are respectively provided with sealing plate connecting holes, and the left and right sides of the first inlet hole are respectively provided with bottom connecting holes corresponding to the sealing plate connecting holes. The inlet sealing plate and the corresponding bottom sealing plate are locked together by a locking fastener that passes through the sealing plate connecting hole and the bottom connecting hole.

[0016] In conjunction with the first aspect, in one possible implementation, the bottom frame includes at least four consecutive borders, each border enclosing a central blank space. The inner side of the frame forms an upward-opening frame limiting groove, and the inner edge of the frame limiting groove is bent in a direction perpendicular to the up and down direction to form a frame overlapping flange. The edge of the bottom sealing plate is overlapped and fixed to the upper side of the frame overlap flange. The edge of the bottom sealing plate is bent downward to form a plate limiting flange. The plate limiting flange extends into the frame limiting groove and can contact the frame edge to limit the displacement of the bottom sealing plate in a direction perpendicular to the up and down direction.

[0017] Secondly, embodiments of this application also provide a rack assembly for a data center, including an upper frame and the aforementioned segmented rack bottom structure, wherein the upper frame is connected to the bottom frame of the segmented rack bottom structure.

[0018] Compared with the prior art, the solution shown in this application has greater design and usage flexibility for the bottom sealing plate by adopting the segmented cabinet bottom structure, which can effectively reduce manufacturing and usage costs. Furthermore, the assembly difficulty of the bottom sealing plate is reduced, effectively shortening the assembly time between the bottom sealing plate and the bottom frame and improving assembly efficiency.

[0022] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0023] It should be noted that when a component is referred to as being "set on" another component, it can be directly on the other component or indirectly on that other component.

[0024] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0026] The existing bottom panel is a one-piece component. Depending on the depth of the rack, different bottom panels of appropriate sizes need to be manufactured, which negatively impacts the control of manufacturing and usage costs. In addition, due to the large size of the bottom panel, manufacturing errors are difficult to control, resulting in assembly errors between it and the rack frame that are also difficult to manage (i.e., the assembly positions of the two are difficult to align). The position of the bottom panel needs to be repeatedly adjusted during assembly, which increases the assembly difficulty and affects assembly efficiency.

[0027] To address the aforementioned issues, this application proposes a segmented cabinet bottom structure, which please refer to in conjunction with the above. Figures 1 to 9 The segmented cabinet bottom structure provided in this application is described below. The segmented cabinet bottom structure includes a bottom frame 100 and multiple bottom sealing plates 200. A gap is formed in the middle of the bottom frame 100. The multiple bottom sealing plates 200 are connected sequentially in the front-to-back direction. After the bottom sealing plates 200 are connected, they form a cover structure that covers the gap in the middle of the bottom frame 100. The outer edge of each bottom sealing plate 200 overlaps and is fixed with the inner edge of the adjacent bottom frame 100. Multiple cable entry openings 300 are provided on the bottom sealing plates 200 located at the front or rear end. The cable entry openings 300 are detachably covered with opening sealing parts 400.

[0028] In this embodiment, the different cabinet depths are the same as the different front and rear dimensions of the cabinet.

[0029] In this embodiment, the bottom sealing plate 200 has sealing plate connecting positions on its edge, and the bottom frame 100 has frame connecting positions corresponding to the sealing plate connecting positions. The sealing plate connecting positions and the frame connecting positions are connected by fasteners. In specific implementation, multiple sealing plate connecting positions are provided along the edge of the bottom sealing plate 200, and multiple frame connecting positions are also provided on the inner edge of the bottom frame 100. The sealing plate connecting positions are through holes, the frame connecting positions are screw holes, and the fasteners are bolts. That is, the bottom sealing plate 200 and the bottom frame 100 are locked together by bolts.

[0030] This embodiment exemplifies an example of setting three bottom sealing plates 200. In other usage scenarios, if the cabinet depth is small, the middle bottom sealing plate 200 can be removed, and the front and rear bottom sealing plates 200 can be used for encapsulation; if the cabinet depth is large, the number of middle bottom sealing plates 200 can be increased, and the total number of bottom sealing plates 200 can reach four or even more.

[0031] Compared with existing technologies, the segmented cabinet bottom structure provided in this application uses multiple bottom sealing plates 200 joined together in the front-to-back direction to form a cover structure. The cover structure is segmented, providing the same sealing function as traditional bottom sealing plates. Depending on the cabinet depth, different numbers of bottom frames 100 can be selected for splicing, eliminating the need to manufacture bottom sealing plates separately for different cabinets. The bottom sealing plates 200 of this application offer greater design and usage flexibility, effectively reducing manufacturing and usage costs. Furthermore, due to the joint design of multiple bottom sealing plates 200, the size of each individual bottom sealing plate 200 is smaller, resulting in less manufacturing error and reduced cumulative assembly errors. Therefore, when assembling a single bottom sealing plate 200 with the bottom frame 100, the connection position is easier to align, eliminating the need for repeated adjustments during assembly. This reduces the assembly difficulty of the bottom sealing plates 200, effectively shortening the assembly time between the bottom sealing plates 200 and the bottom frame 100, and improving assembly efficiency.

[0032] In some embodiments, see Figure 3 The inlet opening 300 includes a first inlet hole 310 and a second inlet hole 320. The first inlet hole 310 is a rectangular hole, and the second inlet hole 320 is a circular hole. The opening sealing component 400 includes an inlet sealing plate 410 for covering the first inlet hole 310 and a blind hole sealing ring 420 for sealing the corresponding blind hole of the second inlet hole 320. The area of ​​the first inlet hole 310 is larger than the area of ​​the second inlet hole 320. Furthermore, the inlet sealing plate 410 is a rigid plate, such as an aluminum alloy plate, and the blind hole sealing ring 420 is an elastic component, such as a rubber component.

[0033] Server racks typically have dozens, even hundreds or thousands, of data cables. By properly designing the opening area of ​​the first cable inlet hole 310, bundled cables can pass through it, significantly improving cabling and maintenance efficiency. Power cables (especially those for individual devices) are usually far fewer in number than data cables and are thicker and stiffer. The circular second cable inlet hole 320 provides a neat path for single or small numbers of power cables. By separating power cables from data cables using the first and second cable inlets 310 and 320, the design requirements for separating strong and weak currents are met, helping to reduce electromagnetic interference. The circular second cable inlet hole 320 can also be used for temporary, sporadic cable connections, such as cables for environmental monitoring sensors and serial port management cables, allowing this application to accommodate more wiring needs. Furthermore, by installing an inlet sealing plate 410 and a blind hole sealing ring 420 at the opening, the integrity and sealing of the base plate are maintained when no wiring is being done, preventing contamination inside the rack during construction.

[0034] In some embodiments, see Figure 7 The blind hole sealing ring 420 includes an outer ring body 421 and a sealing pad 422. The sealing pad 422 seals and covers the internal opening of the outer ring body 421. The outer ring body 421 has a snap-fit ​​receiving groove 423 on its outer periphery, which snaps and matches the edge of the second snap-fit ​​hole. Under the premise of meeting assembly stability, it can effectively seal the second inlet hole 320. The outer ring body 421 and the sealing pad 422 are integrally formed rubber components.

[0035] Optionally, the bottom of the snap-fit ​​receiving groove 423 is provided with a snap-fit ​​adaptation protrusion 424, which extends circumferentially along the outer ring body 421. The protrusion height of the snap-fit ​​adaptation protrusion 424 is less than the depth of the snap-fit ​​receiving groove 423. The upper side of the snap-fit ​​adaptation protrusion 424 is spaced apart from the upper wall of the snap-fit ​​receiving groove 423, and a snap-fit ​​adaptation space is formed between them; the lower side of the snap-fit ​​adaptation protrusion 424 is spaced apart from the lower wall of the snap-fit ​​receiving groove 423, and a snap-fit ​​adaptation space is formed between them. In this embodiment, the upper and lower side walls of the snap-fit ​​receiving groove 423 can engage with the two end faces of the second inlet hole 320 for locking and limiting. At this time, the snap-fit ​​adapter protrusion 424 abuts against the inner wall surface of the second inlet hole 320. The upper side wall of the snap-fit ​​receiving groove 423 and the upper side wall of the snap-fit ​​adapter protrusion 424 can engage with the two end faces of the second inlet hole 320 for locking and limiting. The lower side wall of the snap-fit ​​receiving groove 423 and the lower side wall of the snap-fit ​​adapter protrusion 424 can engage with the two end faces of the second inlet hole 320 for locking and limiting. It can be seen that this embodiment provides multiple snap-fit ​​adaptation methods, which can adapt to the assembly requirements of plates with different thicknesses and improve the flexibility of the blind hole sealing ring 420.

[0036] In some embodiments, see Figures 4 to 6The mating edge of the bottom sealing plate 200 is bent downwards to form a mating flange 210, which can abut against the mating flanges 210 on adjacent bottom sealing plates 200. The mating flange 210 effectively increases the mating area between two adjacent bottom sealing plates 200, preventing the edges of the two adjacent bottom sealing plates 200 from misaligning and overlapping during mating, thus improving the reliability of the mating operation. At the same time, by setting the mating flange 210, the torsional and bending resistance of the bottom sealing plate 200 can also be enhanced, improving the structural strength and rigidity of the bottom sealing plate 200.

[0037] In practice, the bottom sealing plate 200 at the front end can be provided with a mating flange 210 only on the rear side, the bottom sealing plate 200 at the rear end can be provided with a mating flange 210 only on the front side, and the bottom sealing plate 200 in the middle needs to be provided with mating flanges 210 on both the front and rear sides. In this way, while keeping the number of bottom sealing plates 200 at the front end and the rear end unchanged (one of each), the assembly requirements of cabinets of different depths can be met by adjusting the number of bottom sealing plates 200 in the middle.

[0038] In some embodiments, see Figure 1 , Figure 2 , Figures 4 to 7 The edge of the inlet sealing plate 410 overlaps and is fixed to the edge of the first inlet hole 310 to accommodate the sealing of the large-area opening of the first inlet hole 310. Simultaneously, the inlet sealing plate 410 can be easily removed. The blind hole sealing ring 420 is an elastic component. The edge of the blind hole sealing ring 420 is engaged and fixed to the edge of the second inlet hole 320. Assembly is completed by pressing the blind hole sealing ring 420 into the second inlet hole 320 until the two are engaged. The assembly process is simple.

[0039] In some embodiments, see Figures 4 to 7 The edge of the first inlet hole 310 is provided with a cable protection component 500 to prevent the edge of the first inlet hole 310 from abrading the cable.

[0040] In some embodiments, see Figure 3To fully utilize the space on the bottom sealing plate 200, a first cable inlet hole 310 is provided, extending in the left-right direction; multiple second cable inlets 320 are provided, spaced apart in the left-right direction. Each second cable inlet hole 320 is located in front of the first cable inlet hole 310, or each second cable inlet hole 320 is located behind the first cable inlet hole 310. In this embodiment, the second cable inlets 320 are arranged in the same direction, which can guide cables (such as power cables) to enter from one side of the first cable inlet hole 310, making the bottom area of ​​the cabinet very neat and convenient for installing a vertical cable organizer at the rear of the cabinet for cable management. When it is necessary to inspect or replace a cable, technicians can easily find the corresponding cable inlet hole according to the cable type (power / data) and pull out or insert the cable, which conforms to the standardized and modular layout concept and facilitates subsequent operation and maintenance management. In addition, the distribution of the first inlet hole 310 and the second inlet hole 320 in this embodiment is relatively regular, which reduces the weakening of the structural strength of the bottom sealing plate 200 by the openings, maximizes the overall load-bearing efficiency of the bottom sealing plate 200, and reduces the risk of local deformation.

[0041] Optionally, the centerline of the first inlet hole 310 coincides with the centerline of the corresponding bottom sealing plate 200, and multiple second inlet holes 320 are symmetrically distributed on the left and right.

[0042] In some embodiments of the cable protection component 500, see Figures 3 to 7 The front and rear edges of the first inlet hole 310 extend downwards to form a protective flange 510, which serves as a cable protection component 500. The protective flange 510 transforms sharp edges into smooth, rounded surfaces, significantly increasing the cable's contact area and thus preventing the risk of the cable being scratched or cut. Simultaneously, the protective flange 510 disperses stress and friction over a larger area, preventing stress concentration and extending the cable's fatigue life. The protective flange 510 ensures that the cable remains in contact with a smooth, rounded surface after insertion, providing long-term, reliable protection for the cable.

[0043] Optionally, the left and right edges of the first inlet hole 310 also extend downward to form protective flanges 510.

[0044] In other embodiments of the cable protection component 500, the four edges of the first inlet hole 310 are wrapped with an elastic protective strip, such as a rubber strip. The protective strip is the cable protection component 500, which is extended along the edge of the first inlet hole 310 by means of adhesion, snap-fit, or other methods.

[0045] It should be understood that the edge of the second inlet hole 320 may also be provided with a cable protection element 500 similar to that of the first inlet hole 310 to protect the cable passing through it, which will not be elaborated here.

[0046] In some embodiments, see Figure 2 and Figure 3 The inlet sealing plate 410 is a rectangular plate that conforms to the shape of the first inlet hole 310. The left and right ends of the inlet sealing plate 410 are respectively provided with sealing plate connecting holes. The left and right sides of the first inlet hole 310 are respectively provided with bottom connecting holes 201 corresponding to the sealing plate connecting holes. The inlet sealing plate 410 and the corresponding bottom sealing plate 200 are locked together by a locking fastener 600 passing through the sealing plate connecting holes and the bottom connecting holes 201. By providing sealing plate connecting holes at both ends of the length of the inlet sealing plate 410, after connecting with the bottom sealing plate 200, the displacement of the inlet sealing plate 410 can be effectively restricted in the length, thickness, and width directions. At the same time, it can prevent warping at both ends of the length. Without needing to provide sealing plate connecting holes at both ends of the width of the inlet sealing plate 410, the inlet sealing plate 410 can effectively fit onto the bottom sealing plate 200, forming a reliable cover for the first inlet hole 310. As can be seen, this embodiment reduces the number of sealing plate connection holes, thereby effectively shortening the disassembly and assembly time of the inlet sealing plate 410, and also reducing the problem of affecting the structural strength of the bottom sealing plate 200 due to too many bottom connection holes 201 around the first inlet hole 310.

[0047] In practice, the left and right ends of the inlet sealing plate 410 are respectively provided with a sealing plate connection hole, and the left and right sides of the first inlet hole 310 are respectively provided with a bottom connection hole 201, so as to minimize the number of openings.

[0048] In some embodiments, see Figures 1 to 4 The bottom frame 100 includes at least four sequentially connected borders 110, each border 110 enclosing a central opening. The inner side of each border 110 forms an upward-opening frame retaining groove 1101, the inner edge of which is bent in a direction perpendicular to the vertical direction to form a frame overlapping flange 120. Figures 6 to 9 As shown, the edge of the bottom sealing plate 200 is overlapped and fixed to the upper side of the frame overlap flange 120. The edge of the bottom sealing plate 200 is bent downward to form a plate limiting flange 220. The plate limiting flange 220 extends into the frame limiting groove 1101 and can contact the frame 110 to limit the displacement of the bottom sealing plate 200 in the direction perpendicular to the vertical direction. In this embodiment, by setting the plate limiting flange 220 and the frame limiting groove 1101, the bottom sealing plate 200 can be assisted in positioning in the direction perpendicular to the vertical direction when it is installed, reducing the difficulty of aligning the bottom sealing plate 200 with the bottom frame 100 and further improving assembly efficiency.

[0049] In some embodiments, see Figure 8 and Figure 9Each bottom sealing plate 200 has its left edge extending outward to form a left overlapping edge 230, and the left edge of the left overlapping edge 230 bends downward to form a limiting flange; the right edge of each bottom sealing plate 200 has its right edge extending outward to form a right overlapping edge 240, and the right edge of the right overlapping edge 240 bends downward to form a limiting flange. In this embodiment, limiting is preferably performed in the left-right direction. The sealing plate connection position is an elongated oval hole extending in the front-back direction, and the frame connection position is a screw hole. During assembly, the bottom sealing plate 200 can move in the front-back direction. The elongated oval hole absorbs manufacturing and assembly errors, improving the smoothness of assembly.

[0050] In some embodiments, see Figures 6 to 9 The frame 110 includes a top plate 111, a side plate 112, and a bottom plate 113 connected sequentially from top to bottom. The top plate 111 and the bottom plate 113 are respectively connected to the top and bottom edges of the side plate 112. The top plate 111, side plate 112, and bottom plate 113 enclose a frame groove 1102 that opens into the open area. The bottom plate 113 protrudes inward from the top plate 111, and its inner edge bends upward to form a frame support flange 114. An upwardly opening frame limiting groove 1101 is formed between the frame support flange 114 and the open end face of the frame groove 1102. The upper edge of the frame support flange 114 bends in the vertical direction to form a frame overlapping flange 120. The height of the frame support flange 114 is lower than the height of the top plate 111.

[0051] Optional, see below Figures 4 to 7 In the two frame borders 110, the frame overlapping flange 120 extends in a direction away from the frame side panel 112. (See also...) Figure 4 , Figure 8 and Figure 9 In the two side frames 110, the frame overlap flange 120 extends toward the side panel 112 of the frame.

[0052] Optionally, the inner edge of the frame top plate 111 is bent downward to form a top connecting flange 115, which can be connected to other auxiliary brackets in the rack assembly used in the data center.

[0053] Based on the same inventive concept, this application also provides a rack assembly for a data center, including an upper frame 700 and the above-mentioned segmented rack bottom structure, wherein the upper frame 700 is connected to the bottom frame 100 of the segmented rack bottom structure.

[0054] In this embodiment, the upper frame 700 has multiple downward-extending columns, and the bottom of each column is connected to the junction of two adjacent side frames 110.

[0055] Compared with the prior art, the rack assembly for data centers provided in this application adopts the above-mentioned segmented rack bottom structure, which makes the design and use of the bottom sealing plate 200 more flexible and can effectively reduce manufacturing and use costs. In addition, the assembly difficulty of the bottom sealing plate 200 is reduced, which effectively shortens the assembly time between the bottom sealing plate 200 and the bottom frame 100 and improves assembly efficiency.

[0056] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
