Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0051] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0052] The embodiment of the present application provides a hard disk backplane mounting structure, which is applied to a chassis 1, such as Figure 1 and Figure 2As shown, it includes a backplane body 2 and a fixed bracket 3. The fixed bracket 3 and the backplane body 2 are detachably connected together by a connector 15. The fixed bracket 3 and the backplane body 2 are assembled together to form a backplane module. The backplane module is installed in the chassis 1 to facilitate the installation and positioning of the backplane body 2. Specifically, the inner wall of the chassis 1 is provided with a slide groove 4. The two slide grooves 4 are vertically symmetrically installed on the two inner walls of the chassis 1, and the sliding direction of the slide groove 4 is parallel to the depth direction of the chassis 1, so as to achieve enhanced fixation of the backplane body 2 from both ends. When installing the backplane body 2, first adjust the fixed bracket 3 connected to the backplane body 2 to slide vertically in the direction parallel to the depth of the chassis 1 and install it in the slide groove 4, so that the backplane body 2 is installed in the chassis 1.

[0053] Further, such as Figure 3 As shown, a limiting groove 6 is provided on the side of the fixing bracket 3 away from the back plate body 2, and the length direction of the limiting groove 6 is perpendicular to the depth direction of the chassis 1, as shown in FIG. Figure 1 As shown, the X-axis direction is the depth direction of the chassis 1. Limiting grooves 6 are respectively provided at both ends of the length of the fixed bracket 3, and the two limiting grooves 6 are symmetrically arranged at both ends of the fixed bracket 3 along the direction perpendicular to the depth of the chassis 1. A limiting block 7 is slidably installed in the limiting groove 6 along the direction perpendicular to the depth of the chassis 1. When the fixed bracket 3 is installed in the slide 4, and the groove of the limiting groove 6 is connected with the groove of the slide 4 to form a limiting space, the limiting block 7 is adjusted to slide toward the bottom of the slide 4 to the limiting space, so that the fixing bracket 3 and the back panel body 2 on one side of the fixing bracket 3 are positioned through the cooperation of the limiting block 7, the limiting groove 6 and the slide 4. When the back panel body 2 needs to be removed, the limiting block 7 is adjusted to move out of the limiting space. At this time, the fixing bracket 3 and the back panel body 2 can be easily removed from the chassis 1.

[0054] like Figure 3 As shown, the fixed bracket 3 in this embodiment is fixedly connected to the reinforcing edge 8 along both sides parallel to the depth direction of the chassis 1, and the reinforcing edge 8 is bent to one side perpendicular to the length direction of the fixed bracket 3 to form a limit slot 6, and the limit slot 6 includes an upper slot 601 and a lower slot 602, wherein the upper slot 601 and the lower slot 602 are respectively arranged on the upper and lower side surfaces of the fixed bracket 3 parallel to the depth direction of the chassis 1, when the limit block 7 is slidably connected in the limit slot 6, the upper and lower ends of the limit block 7 are respectively slidably connected in the upper slot 601 and the lower slot 602 to prevent the limit block 7 from falling out of the limit slot 6; and the reinforcing edge 8 can reinforce the fixed bracket 3 to improve the strength of the fixed bracket 3.

[0055] Furthermore, since a number of connectors, LED lights, etc. are installed on the side of the backplane body 2, in order to ensure that the backplane body 2 can be installed in the corresponding position in the chassis 1 without interfering with the devices on one side of the backplane body 2, a guide pin 9 is installed on the side of the fixing bracket 3 close to the backplane body 2, and two guide pins 9 are provided on the side wall of the slide 4 along the depth direction parallel to the chassis 1. The inner wall of the slide 4 is provided with a positioning hole 10 corresponding to the guide pin 9. The fixing bracket 3 is adjusted to be installed in the slide 4 in the direction in which the guide pin 9 and the positioning hole 10 are installed. At the same time, the amount of shaking during the assembly of the backplane module is reduced, and the stability of the backplane body 2 in the front-to-back direction is improved. By providing an opening in the side wall of the slide 4 to achieve the matching of the guide pin 9, the left and right and up and down degrees of freedom of the hard disk fixing bracket 3 are limited, ensuring that the shaking during the assembly process is small and does not damage the devices. The characteristic design of the slide 4 in the chassis 1 allows it to be fully reused on the left and right sides.

[0056] like Figure 4 and Figure 5 As shown, positioning holes 10 are symmetrically provided on both side walls of the slide 4 to achieve the same structure of the slide 4 on both sides of the inner wall of the chassis 1. The slide 4 can be installed on either side to achieve the installation and positioning of the fixed bracket 3 and the back panel body 2 on one side of the fixed bracket 3.

[0057] In a specific embodiment, Figure 8 and Figure 9 As shown, in order to achieve efficient tool-free installation of the back panel module, a limiting protrusion 701 is fixedly connected to the side of the limiting block 7 near the bottom of the limiting slot 6. The limiting protrusions 701 are arranged in groups of two along the depth direction parallel to the chassis 1, and three groups of limiting protrusions 701 are arranged at the bottom of the limiting slot 6 along the depth direction perpendicular to the chassis 1. A first limiting hole 11 and a second limiting hole 12 corresponding to the limiting protrusion 701 are provided at the bottom of the limiting slot 6. The first limiting hole 11 and the second limiting hole 12 are arranged in sequence along the length direction of the limiting slot 6. The number and position of the first limiting hole 11 and the second limiting hole 12 are arranged corresponding to the number and position of the limiting protrusion 701. When the back panel body 2 is not positioned, the limiting protrusion 701 is correspondingly inserted into the first limiting hole 11, that is, the limiting block 7 corresponds to the "Unlocked" identification position on the limiting slot 6. The "Unlocked" mark is set at the position of the limit slot 6 away from the bottom side wall of the slide slot 4, and the "Locked" mark is set at the position of the limit slot 6 close to the bottom side wall of the slide slot 4; when the back panel body 2 needs to be positioned, the limit block 7 is adjusted to slide along the limit slot 6 toward the bottom of the slide slot 4. At this time, the limit protrusion 701 slides from the first limit hole 11 to the second limit hole 12, that is, the limit block 7 corresponds to the "Locked" mark position on the limit slot 6 to achieve positioning of the back panel body.

[0058] It should be noted that, in this embodiment, the first limiting hole 11 and the second limiting hole 12 are set to the same structure, and the installation end surfaces of the first limiting hole 11 and the second limiting hole 12 are set to inclined end surfaces, so that the limiting protrusion 701 can cooperate and pass through the first limiting hole 11 and the second limiting hole 12, that is, the first limiting hole 11 and the second limiting hole 12 in this embodiment are both set as salad holes. Through the setting of the first limiting hole 11 and the second limiting hole 12, the limiting protrusion 701 on the limiting block 7 and the first limiting hole 11 and the second limiting hole 12 respectively form fixed points, thereby realizing the locking and release of the position of the back panel body 2.

[0059] Furthermore, in order to ensure that the enhanced positioning of the back panel body 2 is achieved through the cooperation between the limit block 7, the limit groove 6 and the slide groove 4, the limit block 7 is set to slide along the limit groove 6 and elastically adhere to the limit groove 6, thereby ensuring the position stability of the limit block 7 in the limited space; a deformation groove 702 is provided on the bottom side wall of the limit block 7 near the limit groove 6, and the deformation groove 702 is set to a long strip shape, and several deformation grooves are provided on the side wall of the limit block 7, and elastic arms 703 are provided between the deformation grooves 702. Through the setting of the deformation groove 702 and the elastic arm 703, a certain displacement deformation can be generated during the sliding process of the limit block 7 along the limit groove 6, which can not only ensure the sliding of the limit block 7 along the limit groove 6, but also enhance the positioning of the back panel body 2.

[0060] It should be noted that in this embodiment, the limit block 7 is made of plastic or rubber, that is, the limit block 7 itself has a certain elastic deformation ability, so as to ensure that when the limit block 7 is adjusted to slide into the limit space, it can elastically fit within the limit space, thereby ensuring that the back panel module is locked firmly. In addition, the limit block 7 is configured as a hollow type, that is, by configuring the middle portion of the limit block 7 to be hollow, so that the limit block 7 can achieve a certain deformation ability while positioning the back panel body 2.

[0061] In a specific embodiment, Figure 6 As shown, in order to ensure that the limit block 7 is adjusted to prevent it from falling out of the two ends of the limit slot 6 during the sliding process along the limit slot 6, stop plates 13 are fixedly connected to the two ends of the limit slot 6 in the length direction, and when the limit block 7 slides to the corresponding position in the limit slot 6, it is limited by the stop plate 13.

[0062] like Figure 6As shown, in order to ensure that the limit block 7 can slide stably along the limit slot 6, limit ribs 14 are fixedly connected to both ends of the limit block 7 along the direction parallel to the depth of the chassis 1. When the limit block 7 is slidably installed in the limit slot 6, the limit ribs 14 are slidably engaged with the side walls of the limit slot 6, so that the setting of the limit ribs 14 plays a supporting and guiding role in the sliding of the limit block 7. Furthermore, the limit ribs 14 are respectively arranged on the side close to the bottom of the limit slot 6 or the side close to the opening of the limit slot 6 at both ends of the limit block 7 along the direction perpendicular to the sliding direction of the limit block 7. In this embodiment, the limit rib 14 in the upper notch 601 is fixedly connected to the side of the limit block 7 close to the opening of the limit slot 6, and the limit rib 14 in the lower notch 602 is fixedly connected to the side of the limit block 7 close to the bottom of the limit slot 6. The setting of the limit ribs 14 can avoid the problem of foolproofing during the assembly of the limit block 7.

[0063] It should be noted that installation notches are provided on the reinforcing edges 8 on the upper and lower sides of the fixed bracket 3, wherein the installation notches are arranged near the position where the limiting groove 6 is located, and the length of the installation notch along the reinforcing edge 8 is greater than or equal to the width of the limiting block 7, so that the limiting block 7 can be slidably fitted into the limiting groove 6 through the installation notch, thereby facilitating the assembly of the limiting block 7 and the limiting groove 6.

[0064] Specifically, the openings of the two slide grooves 4 inside the chassis 1 in the present application are arranged relative to each other. After the fixed bracket 3 is installed in the chassis 1, the depth direction of the limit groove 6 and the depth direction of the slide groove 4 are arranged perpendicular to each other, and the width of the slide groove 4 is set to be greater than the width of the limit groove 6, so that when the back panel body 2 is installed in the chassis 1, the groove of the limit groove 6 is connected with the groove of the slide groove 4, ensuring that the fixed bracket 3 and the limit groove 6 on the fixed bracket 3 can be accommodated in the slide groove 4, and the limit block 7 is further adjusted to be installed in the limit space to achieve enhanced fixation of the fixed bracket 3.

[0065] In this embodiment, if Figure 10 and Figure 11 As shown, in this embodiment, the backplane body 2 is configured as a 4-port backplane, and the backplane body 2 and the fixing bracket 3 are detachably connected together via a connector 15. Specifically, the connector 15 is provided on the side of the fixing bracket 3 close to the backplane body 2, and a connecting hole 16 corresponding to the connector 15 is opened on the backplane body 2; in this embodiment, the connector 15 is selected as an I-nail, and a plurality of I-nail are provided on one side of the backplane body 2, that is, a plurality of connecting holes 16 are installed along a direction parallel to the depth of the chassis 1, so that the backplane body 2 is installed on one side of the fixing bracket 3. Figure 2 As shown, at least three 4-port backplanes are connected to one side of the fixing bracket 3 in a direction parallel to the depth of the chassis 1 , so that multiple backplane bodies 2 can be installed and positioned simultaneously through one fixing bracket 3 .

[0066] like Figure 11 As shown, since the backplane body 2 has a variety of specifications and configurations, that is, in actual use, according to the number of connectors to be installed, a 12-port backplane can also be selected. In order to make the hard disk backplane mounting structure in this embodiment applicable to the installation of a 12-port backplane, a hard disk frame 24 is set in the chassis 1. The hard disk frame 24 in this embodiment is compatible with a 12-port backplane or a 4-port backplane. By setting the hard disk frame 24 to have a partition near the side of the slide 4, a fixing member 18 is set on the partition. A reserved gap 17 is set between the hard disk frame 24 and the slide 4. The length direction of the reserved gap 17 is perpendicular to the depth direction of the chassis 1. The reserved gap 17 is directly used to accommodate the 12-port backplane. In this case, it is not necessary to assemble the 12-port backplane with the fixing bracket 3. It is only necessary to set the fixing member 18 on the side of the hard disk frame 24 near the slide 4. The fixing member 18 passes through the fixing hole 19 on the 12-port backplane to achieve the installation and fixation of the 12-port backplane.

[0067] Furthermore, the connection hole 16 is set to be long and narrow. Specifically, in this embodiment, the connection hole 16 is set to a gourd hole. The length direction of the connection hole 16 is perpendicular to the depth direction of the chassis 1. Specifically, the length direction of the connection hole 16 on the 4-port backplane is perpendicular to the depth direction of the chassis 1, so that when the backplane body 2 is switched from a 12-port backplane to a 4-port backplane, the fixing parts 18 on the hard disk frame 24 are avoided through the long and narrow connection holes 16; at the same time, through holes are also opened at both ends of the backplane body 2, and the through holes correspond to the positions of the fixing parts 18 at both ends of the hard disk frame 24 in the length direction. The fixing parts 18 at both ends are avoided by setting the through holes.

[0068] It should be noted that since the back panel body 2 is installed on one side of the hard disk frame 24, several LED lights are installed on the back panel body 2, and avoidance holes 25 are opened on the hard disk frame 24 at positions corresponding to the LED lights to avoid the LED lights.

[0069] like Figure 12 and Figure 13 As shown, in order to enhance the position stability of the backplane main body 2 installed in the chassis 1, a mounting part 20 is also provided on the backplane main body 2, and a mounting hole 21 corresponding to the position of the mounting part 20 is provided on the backplane main body 2. The specific mounting part 20 is selected as a hand screw, which passes through the mounting hole 21 through the mounting part 20 and is tightened to enhance the position stability between the backplane main body 2 and the hard disk frame 24.

[0070] In a specific embodiment, operating notches 22 are respectively provided on both side walls of the slide groove 4 along the sliding direction. The provision of the operating notches 22 can facilitate the staff to adjust the limit block 7 to slide along the limit groove 6 to unlock and lock.

[0071] The slide 4 in this embodiment is fixedly installed on the inner wall of the chassis 1 through a connector 15 that passes through the bottom of the slide 4 and the side wall of the chassis 1. A guide edge 23 structure is provided at the top of the slide 4. Through the provision of the guide edge 23, the fixed bracket 3 can be conveniently slid from the top of the slide 4 into the groove of the slide 4. At the same time, the guide edge 23 can also prevent mutual displacement to generate iron filings, thereby causing a system short circuit and damaging the machine. A stop block 5 is also provided on the bottom side wall of the slide 4 close to the chassis 1. The stop block 5 is used to limit the fixed bracket 3 that slides into the slide 4.

[0072] It should be noted that the connecting member 15 in this embodiment includes but is not limited to one or more of screws, SMD studs, bolts, self-tapping screws, rivets, I-nail and pins.

[0073] Specific implementation process: first, the fixed bracket 3 and the back panel body 2 are detachably connected together through the connecting piece 15 to form a back panel module, and then the back panel module is vertically slid along the slide groove 4 to be installed in the chassis 1, so that the back panel body 2 is installed in the chassis 1; then the limit block 7 is adjusted to slide toward the bottom of the slide groove 4 until the groove of the limit groove 6 is connected with the groove of the slide groove 4 to form a limit space, that is, at this time the limit protrusion 701 moves from the first limit hole 11 position to the second limit hole 12, and the corresponding limit block 7 moves from the "Unlocked" mark position to the "Locked" mark position to realize the locking positioning of the back panel body 2; when the back panel body 2 needs to be removed, the limit block 7 is adjusted to be moved out of the limit space, and at this time the fixed bracket 3 connected to the back panel body 2 can be conveniently taken out of the chassis 1.

[0074] When the back panel body 2 is to be removed, the limit block 7 is adjusted to move out of the limited space, thereby solving the problem of cumbersome installation and low assembly efficiency of the hard disk back panel, and achieving the technical effect of tool-free installation and efficient disassembly of the hard disk back panel.

[0075] Furthermore, by setting the limit block 7 that slides left and right along the length direction of the limit groove 6 to be hollow, and at the same time setting a deformation groove 702 on the bottom side of the limit block 7 close to the limit groove 6, and an elastic arm 703 between the deformation grooves 702, the limit block can have a certain deformation ability. On the one hand, it can ensure that the limit block 7 is adjusted to the second limit hole 12 along the first limit hole 11 on the limit groove. On the other hand, the deformable limit block 7 can be inserted into the limit space to achieve elastic and close fit with the limit space, thereby improving the positioning stability of the limit block 7 on the back panel body 2.

By setting the length direction of the fixing hole 19 parallel to the depth direction of the chassis 1, the above configuration can achieve compatibility between the fixing hole 19 and the connection hole 16 on the 4-port back panel.

[0077] By setting the length direction of the fixing holes 19 on the 12-port backplane and the length direction of the connection holes 16 on the 4-port backplane to be perpendicular to each other, efficient layout and utilization of the space in the chassis 1 can be achieved by coordinating the positions and directions of existing components.
