[0037] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] The embodiment of the present application provides a server device supporting hot plugging of hard disks, such as Figure 1 and Figure 3 As shown, it includes a plurality of support columns 1 and a chassis 2 with at least one open end, wherein two support columns 1 form a group, and at least two groups are arranged along the depth direction of the chassis 2, and both are arranged vertically along the height direction of the chassis 2, and the chassis 2 is disassembled and installed between the two groups of support columns 1 through a connecting piece. A slide rail 3 and a hard disk bracket 5 for accommodating a hard disk body 4 are arranged in the chassis 2, and the inner side wall of the chassis 2 is installed with the slide rail 3, and the two slide rails 3 are symmetrically installed on both sides of the open end of the chassis 2, so that the hard disk bracket 5 can be slidably connected in the chassis 2 through the slide rail 3.

[0039] At the same time, the connecting fixing plate 6 is removed from the support column 1 away from the open end of the chassis 2. The fixing plate 6 is tightly attached to the outer wall of the chassis 2, and one side of the fixing plate 6 is connected to the support column 1, and the other side is connected to the chassis 2. When the hard disk bracket 5 slides out of the chassis 2, in order to avoid uneven force on the chassis 2, which may cause the chassis 2 and its components to deflect, the fixing plate 6 can be set to fix the chassis 2 and the support column 1 at the rear of the chassis 2 through the lever principle to stabilize the position of the chassis 2.

[0040] In this embodiment, the two side edges of the fixing plate 6 are respectively fixedly connected to the first folded edge 601 and the second folded edge 602. The first folded edge 601 and the second folded edge 602 are integrally formed with the fixing plate 6. The length directions of the first folded edge 601 and the second folded edge 602 are perpendicular to each other, wherein the first folded edge 601 is arranged close to the support column 1 away from the open end of the chassis 2, and the length direction of the second folded edge 602 extends along the depth direction of the chassis 2. The first folded edge 601 is provided with a first through hole 6011, and a plurality of first through holes 6011 are arranged along the height direction of the support column 1. The support column 1 is provided with a first fixing hole 101 corresponding to the first through hole 6011. A connecting piece passes through the first through hole 6011 and is inserted into the first fixing hole 101 to achieve the position fixation of the fixing plate 6 and the support column 1. At the same time, the second folded edge 602 is clamped to the outer wall of the chassis 2 to strengthen the pressing contact with the chassis 2.

[0041] A third folded edge 603 is fixedly connected to the edge of the fixing plate 6. The third folded edge 603 is integrally formed with the fixing plate 6. The third folded edge 603 is located on the side opposite to the first folded edge 601. The third folded edge 603 is bent away from the side wall of the chassis 2 to form a reserved gap between the third folded edge 603 and the side wall of the chassis 2 to facilitate maintenance of the fixing plate 6.

[0042] like Figure 3 As shown, an ear plate 7 is removably installed at the open end of the chassis 2, and at least two ear plates 7 are respectively installed on both sides of the open end of the chassis 2. A connecting through hole 701 is opened on the ear plate 7, and a second fixing hole corresponding to the connecting through hole 701 is provided on the support column 1 near the open end of the chassis 2. A plurality of second fixing holes are provided along the height direction of the support column 1. When the chassis 2 is installed between the support columns 1, the connecting through hole 701 is penetrated by a connecting piece and connected to the second fixing hole to enhance the position stability of the chassis 2.

[0043] like Figure 6 and Figure 7As shown, in this embodiment, the chassis 2 is suitable for storing high-density hard disks, so the hard disk bracket 5 contains a high-density hard disk body 4. In order to ensure the stability of the chassis 2 and its internal components during the maintenance of the hard disk, the components in the chassis 2 are arranged with high density and stability. Specifically, the chassis 2 also includes a tank chain 8 and a circuit board 9. The circuit board 9 is interconnected with the hard disk body 4 through two MCIO signal lines and one power line, that is, the circuit board 9 and the hard disk body 4 are connected by a connecting line, and the connecting line is inserted in the tank chain 8. The arrangement of the tank chain 8 realizes a perfect layout of the cables, so as to strengthen the protection of the cables during the removal and maintenance of the hard disk.

[0044] like Figure 7 As shown, the height of the chassis 2 in this embodiment is 5U. Along the height direction of the chassis 2, the slide rail 3, the tank chain 8, the circuit board 9 and the server body 10 are sequentially arranged in the chassis 2. The server body 10 and the circuit board 9 are connected by the plug-in handle to realize the direct plugging of the connector to complete the power supply and signal transmission. The slide rail 3 is arranged on the bottom side wall of the chassis 2, and the slide rail 3 occupies the 2U height of the side wall of the chassis 2. The tank chain 8 is located on both sides of the hard disk bracket 5, that is, the tank chain 8 is arranged along the inner side wall of the chassis 2, and the tank chain 8 is located on the upper part of the slide rail 3, that is, the tank chain 8 occupies the 3U~4U area of ​​the side wall of the chassis 2. The hard disk bracket 5 is located in the middle area of ​​the chassis 2, and its height direction occupies the 1U~4U area; the circuit board 9 and the server body 10 are sequentially arranged on the upper part of the hard disk bracket 5, and its height direction occupies the 5U height area. Through the above arrangement, the high-density layout of the components in the chassis 2 is realized, and the internal space utilization of the chassis 2 is improved to the greatest extent.

[0045] Through the above-mentioned layout setting in the chassis 2, the circuit board 9 and the hard disk body 4 are interconnected, and power supply and signal transmission are realized through cable connection. Since the hard disk node is pullable, it means that the cable from the circuit board 9 to the hard disk body 4 is movable when maintaining the hard disk node. The introduction of the tank chain 8 design can ensure that the cable path is not messy.

[0046] like Figure 8As shown, the slide rail 3 in this embodiment includes an outer rail 301, a middle rail 302 and an inner rail 303, and the inner rail 303, the middle rail 302 and the outer rail 301 are slidably sleeved and connected in sequence, and can slide relative to each other, wherein the outer rail 301 is fixedly installed on the inner wall of the chassis 2 through a connecting piece, and the outer rail 301 is fixedly arranged relative to the chassis 2; the inner rail 303 is fixedly connected to the hard disk bracket 5 through a connecting piece, that is, the inner rail 303 is fixedly arranged relative to the hard disk bracket 5, and the middle rail 302 of the slide rail 3 is slidable relative to the outer rail 301 and the inner rail 303, and the protruding length of the slide rail 3 from the opening end of the chassis 2 is also adjusted by the relative sliding of the outer rail 301, the middle rail 302 and the inner rail 303. When the hard disk bracket 5 is completely stretched out from the open end of the chassis 2, the outer rail 301, the middle rail 302 and the inner rail 303 in the slide rail 3 are in a fully stretched state. At this time, the hard disk body 4 in the hard disk bracket 5 is completely pulled out of the chassis 2, and the hard disk body 4 is pulled out upward for replacement, which is convenient to operate and has high maintenance efficiency. At this time, the chassis 2 is in a power-on state to realize hot-swap maintenance of the hard disk.

[0047] like Fig. 9 and Fig.10 As shown, the tank chain 8 in this embodiment is a plastic part, and the tank chain 8 includes a first connection part 801, a second connection part 802, and an extension part 803 rotatably connected between the first connection part 801 and the second connection part 802. The first connection part 801 and the second connection part 802 are respectively located at two ends of the length direction of the tank chain 8. The first connection part 801 is used to be fixedly connected to the inner wall of the chassis 2, and the second connection part 802 is used to be fixedly connected to the hard disk bracket 5. The first connection part 801 includes a first connection plate 8011 and a connection seat 8012. The connection seat 8012 is fixedly connected to the edge of the first connection plate 8011, and two connection seats 8012 are symmetrically arranged along the two sides of the first connection plate 8011. The connection seat 8012 is provided with a first hinge hole 11, and the first connection plate 8011 is provided with a second through hole 12. The second through hole 12 is penetrated by a connecting member to connect with the inner wall of the chassis 2, so as to fix one end of the tank chain 8 in the chassis 2.

[0048] like Fig.10 As shown, the second connecting part 802 includes a second connecting plate 8021, a fixing seat 8022 and an extension plate 8023. The fixing seat 8022 is fixedly connected to the side wall of the second connecting plate 8021. The fixing seat 8022 is connected to one side of the second connecting plate 8021 along the length direction of the tank chain 8. The extension plate 8023 is connected to both sides of the second connecting plate 8021 along the width direction of the tank chain 8. A third through hole 13 is opened on the fixing seat 8022, and the third through hole 13 is penetrated by a connecting member to connect with the hard disk bracket 5, so as to fix one end of the tank chain 8 with the hard disk bracket 5. The extension plate 8023 is fixedly connected to the first connecting shaft 14.

[0049] like Fig.10 As shown, a plurality of stretching portions 803 are provided between the first connecting portion 801 and the second connecting portion 802 , and the number of the stretching portions 803 can be set according to the required length of the tank chain 8 . The extension part 803 includes a connecting block 8031, a first interconnecting seat 8032 and a second interconnecting seat 8033. The first interconnecting seat 8032 and the second interconnecting seat 8033 are arranged at the ends of the connecting block 8031, that is, the first interconnecting seat 8032 and the second interconnecting seat 8033 are located at both ends of the connecting block 8031 ​​along the length direction of the tank chain 8, and the two first interconnecting seats 8032 are symmetrically arranged at both ends of the connecting block 8031 ​​along the width direction of the tank chain 8. The first interconnecting seat 8032 is fixedly connected to the second connecting shaft 15, and the second connecting shaft 15 is hinged to the first hinge hole 11 to realize the rotatable connection between the first connecting part 801 and the extension part 803. The second interconnecting seat 8033 is provided with a second hinge hole 16, and the second hinge hole 16 is hinged to the first connecting shaft 14 to realize the rotatable connection between the second connecting part 802 and the extension part 803.

[0050] like Fig.10 As described above, the first interconnecting seat 8032 is arranged at a position closer to the central axis of the connecting block 8031 ​​than the second interconnecting seat 8033, and the second connecting shaft 15 on the first interconnecting seat 8032 can be hinged to the second hinge hole 16 on the second interconnecting seat 8033 in another extending part 803, thereby realizing a rotatable connection between multiple extending parts 803.

[0051] like Fig.10 As shown, the thickness of the tank chain 8 is required to be smaller than the thickness of the outer rail 301, the middle rail 302 and the inner rail 303 in the slide rail 3, and it must not affect the pulling of the hard disk bracket 5. The size of the tank chain 8 is configured according to the cable size, and the other end of the tank chain 8 is fixed to the hard disk bracket 5 through the second connecting part 802, so that the tank chain 8 moves together according to the pulling of the hard disk bracket 5. When the hard disk bracket 5 is fully pulled out, the layout of the slide rail 3 and the tank chain 8 ensures the maximum utilization of the space in the lower chassis 2, and does not occupy the space of the server body 10 on the upper chassis 2, while improving the problem of cable layout, forming a high-density layout server architecture.

[0052] Furthermore, since the hard disk bodies 4 in the present embodiment are arranged in a high-density manner, when the hard disk node is in the maintenance state, that is, the hard disk bracket 5 is fully pulled out from the chassis 2, the center of gravity of the entire chassis 2 is obviously moved forward due to the high counterweight of the hard disk node. In order to ensure the reliability and stability of the chassis 2 during the maintenance process, the stability of the chassis 2 is enhanced by the fixing plate 6, and the distance between the front and rear groups of support columns 1 is adjustable, so as to achieve the distance between the front and rear groups of support columns 1 being adjusted according to the depth of the chassis 2, thereby further enhancing the stability of the chassis 2.

[0053] like Fig.11 and Fig.12 As shown, at least two support columns 1 are arranged along the depth direction of the chassis 2, and a guide rail 18 is connected between the two support columns 1 through a limit assembly 17, and the guide rail 18 is supported at the bottom of the chassis 2. The guide rail 18 is arranged in an L shape, and the L-shaped guide rail 18 has a support plate near the center of the bottom of the chassis 2, so as to be more stably supported at the bottom of the chassis 2 through the support plate.

[0054] Further, in this embodiment, the guide rail 18 includes a guide rail 18 body 1801 and a telescopic rail 1802, the guide rail 18 body is connected to the telescopic rail 1802 by sliding sleeve, and the guide rail 18 body and the telescopic rail 1802 can be relatively slidably arranged, the guide rail 18 body is connected to one end of the telescopic rail 1802, and the other end is connected to the support column 1 close to the open end of the chassis 2, and the other end of the telescopic rail 1802 is connected to the support column 1 far from the open end of the chassis 2. Through the above arrangement, the length of the guide rail 18 in this embodiment can be adjusted telescopically. Under normal conditions, the length of the guide rail 18 is set to be able to accommodate a chassis 2 with a depth of 60 cm between the support columns 1, and the adjustment range between the guide rail 18 body and the telescopic rail 1802 is to at least ensure that the depth range of the chassis 2 between the support columns 1 is 60 to 90 cm. Through the above arrangement, when the hard disk bracket 5 is fully extended, by increasing the distance between the front and rear support columns 1, the position stability of the chassis 2 between the support columns 1 is further enhanced under the principle of leverage.

[0055] like Fig.11 and Fig.12 As shown, in order to facilitate the safety and stability between the support columns 1, the limiting components 17 are respectively connected to the two ends of the guide rail 18, so as to be fixedly connected with the two groups of support columns 1 arranged in front and behind through the limiting components 17. The limiting components 17 include a limiting plate 1701, a limiting through hole 1702 and a limiting hook 1703, wherein the limiting plate 1701 is fixedly connected to the end of the guide rail 18, the limiting through hole 1702 is provided on the limiting plate 1701, the end of the guide rail 18 is hinged with the limiting hook 1703, the mounting hole 19 on the support column 1 and the clamping hole 20 corresponding to the limiting hook 1703, when the guide rail 18 is fixed between the two support columns 1, the limiting plate 1701 is penetrated by the connecting piece and connected to the mounting hole 19, and the limiting hook 1703 penetrates the limiting through hole 1702 and is movably clamped in the clamping hole 20, so as to enhance the stability between the support column 1 and the guide rail 18 and the chassis 2.

[0056] Furthermore, a limiting torsion spring 21 is sleeved on the hinge shaft of the limiting hook 1703, and the two ends of the limiting torsion spring 21 are respectively connected to the positioning strips. A positioning piece corresponding to the positioning strip is provided on the limiting plate 1701. The positioning piece passes through the limiting plate 1701 and is fixedly connected to the support column 1.
