[0055] In order to facilitate the movement of the movable body 360 toward the hard disk frame 100 and keep the back plate 200 and the hard disk frame 100 in close contact, the handle assembly 300 further includes an elastic component 381, the two ends of which are respectively in contact with the movable body 360 and the side wall of the sliding groove 347, and the elastic component 381 can be elastically arranged, and the elastic restoring force of the elastic component 381 pushes the movable body 360 toward the direction close to the hard disk frame 100. When the back plate 200 needs to be disassembled, the elastic component 381 is compressed by pushing the movable body 360, so that the second plug 332 is pulled out from the plug-in portion.

[0056] Furthermore, in order to prevent the movable body 360 from being pushed out of the sliding groove 347 under the action of the elastic component 381, a limiting channel 345 is provided on the bottom surface of the sliding groove 347, and the extending direction of the limiting channel 345 is consistent with that of the sliding groove 347. The handle assembly 300 also includes: a limiting component 390, which is provided on the bottom surface of the movable body 360, and at least a part of the limiting component 390 extends into the limiting channel 345, so that when the elastic component 381 pushes the movable body 360 to move, the limiting component 390 and the channel wall of the limiting channel 345 stop each other, thereby limiting the movable body 360.

[0057] The limiting component 390 includes: a third elastic arm 391, which is arranged on the bottom surface of the mobile body 360. The third elastic arm 391 is provided with a fourth hook 392. At least part of the fourth hook 392 is located in the limiting channel 345. The fourth hook 392 and the channel wall of the limiting channel 345 are mutually stopped to limit the mobile body 360. In the process of installing the mobile body 360, the limiting protrusion 344 is first matched with the limiting groove 361. At this time, the bottom surface of the groove applies a force to the third elastic arm 391 to deform it. In the process of gradually pushing the mobile body 360 into the sliding groove 347, the third elastic arm 391 drives the fourth hook 392 to move until the fourth hook 392 extends into the limiting channel 345 under the elastic restoring force of the third elastic arm 391, and then in the assembly process, the mobile body 360 is limited.

[0058] In the specific implementation process, the handle assembly 300 also includes: a bending plate 370, which is arranged below the movable body 360, and the bending plate 370 includes a first plate 371 and a second plate 372. The first plate 371 is provided with a protruding block 373, and the protruding block 373 is connected to the movable body 360 to form a limiting groove 361 between the movable body 360 and the first plate 371; the second plate 372 is connected to the first plate 371, and there is an angle between the first plate 371 and the second plate 372; the guide component 380 is arranged on the first plate 371 and faces the side of the first plate 371 away from the second plug block 332 The guide component 380 is extended, and an elastic component 381 is sleeved on the guide component 380, and the two ends of the elastic component 381 are respectively abutted against the first plate body 371 and the groove wall surface of the sliding groove 347; the third elastic arm 391 is arranged on the second plate body 372, and the third elastic arm 391 extends toward the second plate body 372 away from the second plug block 332. The third elastic arm 391 can be elastically arranged, and a fourth hook 392 is arranged at one end of the third elastic arm 391 away from the second plate body 372; a limiting channel 345 is arranged on the bottom surface of the sliding groove 347, and the limiting channel 345 is connected to the handheld part 320, and at least a part of the fourth hook 392 is engaged in the limiting channel 345. Among them, a through hole 346 is also provided on the sliding groove 347, and the guide component 380 is opposite to the through hole. The guide component 380 is a cylindrical structure, and the elastic component 381 is a spring. During the assembly process of the installation body 340, the action force between the second plug block 332 and the hard disk frame 100 or the back plate 200 is transmitted to the elastic component 381 through the moving body 360, so that the elastic component 381 is compressed, and the guide component 380 extends out through the through hole 346. When the installation body 340 moves to the predetermined installation position, the second plug block 332 is opposite to the corresponding second installation hole 120. At this time, the second plug block 332 is pushed into the second installation hole 120 under the action of the elastic restoring force of the elastic component 381. In addition, by setting the limiting channel 345, the third elastic arm 391 drives the fourth hook 392 to pass through the limiting channel 345 and slide in the limiting channel 345 to limit the movable body 360; when it is necessary to unlock the handle assembly 300, it is only necessary to push the movable body 360 in the reverse direction, the elastic component 381 is compressed, and the second plug block 332 is pulled out from the plug-in portion.

[0059] The difference between this embodiment and the first embodiment is that the installation body 340 and the movable body 360 are set as a split structure, the movable body 360 is slidably set, and the second plug block 332 is set at the end of the movable body 360. Such a setting can be pushed by the elastic force of the elastic component 381 and cooperate with the limiting effect between the fourth hook 392 and the limiting channel 345 to keep the second plug block 332 and the hard disk frame 100 stably matched, thereby reducing the gap between the back plate and the hard disk frame. In the process of inserting the second plug block 332 into the hard disk frame, the fourth hook 392 slides in the limiting channel 345 until it fits with the channel wall of the limiting channel 345 close to the back plate. Under the stopping action of the fourth hook 392 and the channel wall, the movable body 360 is limited to keep the second plug block 332 stable.

[0060] In this application, if Figure 2 As shown, the first connection part 110 includes a plurality of hook members 111, and the second connection part 210 includes: a plurality of first mounting holes 211, and each hook member 111 is hooked in each first mounting hole 211 in a one-to-one correspondence; the hard disk frame 100 is also provided with a second mounting hole 120, and at least part of the fifth connection part 330 is inserted in the second mounting hole 120. Among them, the back plate 200 can be directly hung on the hard disk frame 100 through each first mounting hole 211 and each hook member 111, and the operation is simple and the assembly is convenient. At the same time, the fifth connection part 330 is used to make the back plate 200 and the hard disk frame 100 fit tightly.

[0061] The present application also provides a server, including a backplane structure and a hard disk frame, wherein the backplane structure is arranged on the hard disk frame, and the backplane structure is the backplane structure of the above embodiment.

[0062] This application designs a technical solution for a server hard disk backplane structure, which is mainly applied to a server with 12 hard disks. The backplane design can save the bracket cost by removing the backplane bracket, and can save the labor cost of assembly by designing a tool-free assembly backplane structure. The backplane fastener design has a handle function, which can prevent the operator from directly grabbing the backplane when assembling and disassembling the backplane, avoiding the risk of damage to the components on the board due to being grabbed.

[0063] The hard disk backplane structure designed in this application is installed at the rear end of the server hard disk frame. The backplane is generally a 12-port backplane. In the prior art, it is first assembled on the backplane bracket and then assembled on the hard disk frame. The structural methods for fixing the backplane can be divided into locking flat head screws, loose screws, or spring pins, etc. The use of technical solutions such as backplane brackets and locking screws has the problem of high structural component costs and labor costs. The backplane has no handles, and the hard disk backplane is easily damaged if the components on the board are grabbed for assembly. The present application adopts a technical solution without a hard disk backplane bracket and the fasteners designed on the hard disk backplane bracket have a handle structure function, which can solve the current structural problems of the hard disk backplane.

[0064] 1. Hard disk frame: The server chassis is designed with a hard disk frame, which is compatible with both 12-port and 4-port backplanes. The partition of the hard disk frame is designed with a bend, and the sheet metal is designed with a buckle on the bend (such as Figure 2 As shown), the back panel is fixed with the wine bottle hole (card hole) designed on the back panel (as shown Figure 2 As shown in the figure, the two sides of the bottom of the hard disk frame have a large space on both sides of the hard disk frame and the backplane, so the I-shaped nails are designed to match the gourd holes (as shown in the figure). Figure 2 shown);

[0065] 2. Hard disk backplane: There are two types of hard disk backplane designs, 12-port backplane and 4-port backplane (such as Figures 13 to 16 The hard disk backplane is designed with gourd holes and wine bottle holes to fix the backplane with the hard disk frame. In addition, the backplane is also assembled with backplane fasteners, which also serve to fix the backplane;

[0066] 3. Handle assembly: Figure 4 and Figure 6 As shown in the figure, two types of handle assemblies are assembled on the back panel. One is a handle assembly with only one plastic part. The advantage is that it only has one part and its cost is low, but there is a problem that a large gap needs to be reserved between the fastener and the hard disk frame opening, and the amount of shaking after assembly is relatively large. Therefore, the handle assembly is disassembled into three parts: the installation body 340 (installation body), the return spring (elastic component) and the moving body 360 (as shown in the figure). Figure 7 As shown), the problem of excessive shaking caused by gaps can be solved. The handle assembly is designed to be assembled to the back panel in a tool-free manner, wherein a plurality of snap parts cooperate with the respective snap holes on the back panel 200. When the fasteners are assembled in a dislocated manner, the third hook 3113 is deformed, and a "click" prompt sound is emitted when the assembly is in place. The snap feature (first protruding block) falls into the back panel opening to fix the handle assembly to the back panel. Combined with the back panel snap feature (first plug-in block or second plug-in block), the upward sliding freedom of the back panel can be limited. The two snap features are designed with chamfers, that is, a guide surface is formed (such as Figure 7 As shown in FIG. 1 ), it is easier to unlock and lock the handle assembly. The buckle unlocking position is designed with a flange undercut feature (the second elastic arm 350 can only move downward). Figure 4 As shown. In order to prevent the elastic arm from being damaged due to excessive pulling during the unlocking process, the fastener is designed with a stop feature, that is, the top surface of the mounting body 340 limits the downward movement of the second elastic arm 350. The fastener is designed to pass through the finger space, which is convenient for the operator to pass his fingers through the opening to hold the back panel for assembly and disassembly operations. The handle assembly is in the form of a single plastic part, and its elastic buckle requires a large gap when rotating to unlock. If the gap is too large, the back panel will also shake a lot when assembled to the hard disk frame, which will have an adverse effect on the structural reliability test. Therefore, in the second embodiment provided by the present application, the handle assembly 300 is designed to include a movable body 360, which can effectively reduce the gap between the back panel and the hard disk frame, reduce the shaking of the back panel, and improve the structural precision. The assembled fastener is as shown Figure 6 As shown, the movable body 360 can slide along the arrow direction on the mounting body 340 to fix the hard disk backplane to the hard disk frame or unlock it from the hard disk frame to remove the hard disk backplane;

[0067] 4. Mobile body 360 (such as Figure 8 As shown): The movable body 360 is designed with a Kara feature for fixing the back plate and a chamfer feature for easy assembly (i.e., the third elastic arm 391 and the fourth hook 392 of the above embodiment). A flange feature for sliding unlocking is also designed to facilitate unlocking. The flange features of the base and the slots on both sides form a sliding pair. The part is also designed with a cylindrical feature for fixing the reset spring, which can also form a sliding pair with the opening of the mounting body 340, making the sliding of the buckle more stable and reliable. The part is also designed with a clamping position and chamfer feature with an elastic arm. After the movable body 360 is assembled to the corresponding cavity of the mounting body 340, this buckle can prevent the movable body 360 from falling out;

[0068] 5. Install the body 340 (such as Fig. 9 and Fig.10 As shown in the figure): The mounting body 340 is designed with a flange feature to form a sliding pair with the slot of the moving body 360. The first hook 3111, the second hook 3112 and the third hook 3113 are designed to fix the entire mounting body 340 to the back plate. The part is also designed with a finger space (handle 320) to facilitate the operator to insert his fingers to lift the back plate. Figure 8 and Fig.12 As shown, the part is designed with a resilient snap fit for the moving body 360 and an opening for the cylindrical feature to fit;

[0069] 6. Return spring (such as Figure 7 As shown): Provide reset power to the mobile body 360;

[0070] Specific implementation of the present invention: Assemble the handle assembly: Figure 7As shown, assemble the return spring to the cylinder of the sliding fastener, and then assemble the movable body 360 and the return spring together into the corresponding cavity of the mounting body 340, the slot of the movable body 360 cooperates with the flange of the mounting body 340, and the cylinder of the movable body 360 cooperates with the through hole 346 of the mounting body 340, until a "click" prompt is heard, and the fourth hook 392 of the third elastic arm of the movable body 360 hooks the limiting channel 345 of the mounting body 340; the handle assembly 300 is assembled to the back panel: whether it is a single plastic part mounting body 340 or a three-piece mounting body 340, the assembly method is the same. The fasteners are assembled to the backplane in an up-and-down manner. The buckles with supports and the buckles with elastic arms cooperate with the openings on the backplane. The fasteners are assembled by shifting them until a "click" sound is heard to indicate that they are in place. The backplane is assembled to the hard disk frame: The assembly method of the 12-port backplane and the 4-port backplane is the same. Pass your fingers through the fastener openings to lift the backplane, and assemble the backplane to the hard disk frame by shifting it up and down. The gourd hole and the wine bottle hole on the backplane cooperate with the I-nail and the buckle on the bend of the hard disk frame. The backplane is assembled when a "click" sound is heard to indicate that they are in place.

[0071] The present invention designs a technical solution for a server hard disk backplane structure, which is mainly applied to a server with 12 hard disks. The backplane design can save the bracket cost by removing the backplane bracket, and can save the labor cost of assembly by designing a tool-free assembly backplane structure. The handle assembly is designed with a handle function to prevent the operator from directly grabbing the backplane when assembling and disassembling the backplane, avoiding the risk of damage to the components on the board due to being grabbed.

[0072] The server backplane structure of the present application is designed with 12-port backplane form and 4-port backplane form according to different shipping configurations, and the hard disk frame can be compatible with both forms of backplanes;

[0073] The backplane and the hard disk frame are assembled in an up-and-down staggered manner. The partition of the hard disk frame is designed with buckles to match the wine bottle holes of the backplane, and the I-shaped nails on both sides of the hard disk frame are designed to match the gourd holes of the backplane, which can limit the other eight degrees of freedom of the backplane except the degree of freedom in the upward direction;

[0074] There are fewer components placed on both sides of the hard disk frame and the backplane. The hard disk frame is designed with I-shaped nails and the gourd holes of the backplane, which makes the structure more reliable.

[0075] There are handle assemblies on both sides of the back panel. The handle assemblies are designed with buckles and elastic arms. The handle assemblies are assembled to the back panel in a tool-free manner. The buckles of the buckles are designed to face upwards. The whole is assembled from bottom to top, so that the buckles of the buckles support the back panel when the back panel is lifted.

[0076] The handle assembly is designed with an elastic buckle feature, which cooperates with the opening of the hard disk frame to limit the freedom of the backplane in the upward direction;

[0077] The handle assembly is designed with through holes in the left and right directions, which is convenient for the operator to pass his fingers through and lift the back panel, making it convenient to move the back panel, assemble and disassemble the back panel;

[0078] The advantages of the backplane and hard disk frame in this application are low cost and simple structure;

[0079] During specific installation, the second plug block 332 pushes the movable body 360 to move, and the compression spring provides a reset force. The installation body 340 is designed with a slide, a stop feature, and an anti-slip feature. In this structure, a smaller gap is reserved between the hard disk frame opening and the buckle, and the structure is more reliable.
