[0031] In order to enable those skilled in the art of the present technology to better understand the solution of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0032] An 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 main body 2 and a fixing bracket 3. The fixing bracket 3 is detachably connected to the backplane main body 2 through a connecting member 15. The backplane module is formed by assembling the fixing bracket 3 and the backplane main body 2, and the backplane module is fitted and installed in the chassis 1 to facilitate the installation and positioning of the backplane main body 2. Specifically, sliding grooves 4 are provided on the inner side walls of the chassis 1. The two sliding grooves 4 are vertically symmetrically installed on the two inner side walls of the chassis 1, and the sliding direction of the sliding grooves 4 is parallel to the depth direction of the chassis 1 to achieve strengthening and fixing of the backplane main body 2 from both ends. When installing the backplane main body 2, first adjust the fixing bracket 3 connected to the backplane main body 2 to slide vertically along the direction parallel to the depth of the chassis 1 and install it in the sliding groove 4, so as to install the backplane main body 2 in the chassis 1.

[0033] Further, as Figure 3 shown, a limiting groove 6 is provided on the side of the fixing bracket 3 away from the backplane main body 2. The length direction of the limiting groove 6 is perpendicular to the depth direction of the chassis 1. As Figure 1 shown, the X-axis direction is the depth direction of the chassis 1. The limiting grooves 6 are respectively provided at both ends of the fixing bracket 3 in the length direction. The two limiting grooves 6 are symmetrically arranged at both ends of the fixing 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 fixing bracket 3 is installed in the sliding groove 4 and the groove of the limiting groove 6 communicates with the groove of the sliding groove 4 to form a limiting space, adjust the limiting block 7 to slide towards the bottom of the sliding groove 4 into the limiting space, so as to realize the positioning of the fixing bracket 3 and the backplane main body 2 on one side of the fixing bracket 3 through the cooperation of the limiting block 7 with the limiting groove 6 and the sliding groove 4. When the backplane main body 2 needs to be taken out, adjust the limiting block 7 to move out of the limiting space. At this time, the fixing bracket 3 connected to the backplane main body 2 can be conveniently taken out of the chassis 1.

[0034] As Figure 3 shown, in this embodiment, reinforcing edges 8 are fixedly connected to both sides of the fixing bracket 3 along the direction parallel to the depth of the chassis 1. The reinforcing edges 8 are bent towards the side perpendicular to the length direction of the fixing bracket 3 to form the limiting groove 6. The limiting groove 6 includes an upper notch 601 and a lower notch 602. The upper notch 601 and the lower notch 602 are respectively provided on the upper and lower side surfaces of the fixing bracket 3 along the direction parallel to the depth of the chassis 1. When the limiting block 7 is slidably connected in the limiting groove 6, the upper and lower ends of the limiting block 7 are respectively slidably connected in the upper notch 601 and the lower notch 602 to prevent the limiting block 7 from disengaging from the limiting groove 6; and the reinforcing edges 8 can play a role in strengthening the fixing bracket 3 to improve the strength of the fixing bracket 3.

[0035] Further, since several connectors, several LED lights, etc. are installed on the side of the backplane main body 2, in order to ensure that the backplane main body 2 can be correspondingly installed at the corresponding position in the chassis 1 without interfering with the devices on one side of the backplane main body 2, guide pins 9 are installed on the side of the fixing bracket 3 close to the backplane main body 2, and two guide pins 9 are arranged on the side wall of the sliding groove 4 along the depth direction parallel to the chassis 1. Positioning holes 10 corresponding to the guide pins 9 are formed on the inner side wall of the sliding groove 4. The adjusting fixing bracket 3 is installed in the sliding groove 4 in the direction of the cooperation between the guide pins 9 and the positioning holes 10, while reducing the shaking amount during the assembly of the backplane module and improving the stability of the backplane main body 2 in the front-rear direction. By arranging openings on the side wall of the sliding groove 4 to achieve the cooperation with the guide pins 9, the left-right and up-down degrees of freedom of the hard disk fixing bracket 3 are restricted, ensuring that the shaking amount during the assembly process is small and the devices are not damaged. The characteristic design of the sliding groove 4 in the chassis 1 can make it completely reusable left and right.

[0036] As Figure 4 and Figure 5 shown, positioning holes 10 are symmetrically formed on the two side walls of the sliding groove 4 respectively, so that the sliding groove 4 structures on both sides of the inner side wall of the chassis 1 are the same, and the sliding groove 4 can be installed on any side to achieve the installation and positioning of the fixing bracket 3 and the backplane main body 2 on one side of the fixing bracket 3.

[0037] In a specific embodiment, as Figure 8 and Figure 9 shown, in order to achieve tool-free and efficient installation of the backplane module, a limiting convex block 701 is fixedly connected to the side of the limiting block 7 close to the bottom of the limiting groove 6. Two limiting convex blocks 701 are arranged in a group along the depth direction parallel to the chassis 1, and three groups of limiting convex blocks 701 are arranged on the bottom of the limiting groove 6 along the direction perpendicular to the depth direction of the chassis 1. First limiting holes 11 and second limiting holes 12 corresponding to the limiting convex blocks 701 are formed on the bottom of the limiting groove 6. The first limiting holes 11 and the second limiting holes 12 are arranged in sequence along the length direction of the limiting groove 6, and the number and positions of the first limiting holes 11 and the second limiting holes 12 are correspondingly set with the number and positions of the limiting convex blocks 701; when the backplane main body 2 is not positioned, at this time the limiting convex blocks 701 correspondingly penetrate into the first limiting holes 11, that is, the limiting block 7 corresponds to the "Unlocked" mark position on the limiting groove 6, and the "Unlocked" mark is set at the position of the side wall of the limiting groove 6 far from the bottom of the sliding groove 4, and the "Locked" mark is set at the position of the side wall of the limiting groove 6 close to the bottom of the sliding groove 4; when the backplane main body 2 needs to be positioned, when the limiting block 7 is adjusted to slide along the limiting groove 6 towards the direction close to the bottom of the sliding groove 4, at this time the limiting convex blocks 701 slide from the first limiting holes 11 to the second limiting holes 12, that is, the limiting block 7 corresponds to the "Locked" mark position on the limiting groove 6 to achieve the positioning of the backplane board body.

[0038] It should be noted that in this embodiment, the first limiting hole 11 and the second limiting hole 12 are set to have the same structure, and the installation end faces of the first limiting hole 11 and the second limiting hole 12 are set to be inclined end faces, so as to facilitate the limiting convex block 701 to be fitted and inserted into 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 settings of the first limiting hole 11 and the second limiting hole 12, the limiting convex block 701 on the limiting block 7 forms fixed points with the first limiting hole 11 and the second limiting hole 12 respectively, and then the position locking and release of the backplane main body 2 are realized.

[0039] Furthermore, in order to ensure the strengthened positioning of the backplane main body 2 through the cooperation between the limiting block 7, the limiting groove 6 and the sliding groove 4, when the limiting block 7 slides along the limiting groove 6, it is elastically closely attached to the limiting groove 6, so as to ensure the position stability of the limiting block 7 in the limiting space; a deformation groove 702 is opened on the bottom side wall of the limiting block 7 close to the limiting groove 6. The deformation groove 702 is set to be strip-shaped, and a plurality of them are arranged on the side wall of the limiting block 7. Elastic arms 703 are arranged between the deformation grooves 702. Through the settings of the deformation groove 702 and the elastic arms 703, a certain displacement deformation can be generated during the sliding process of the limiting block 7 along the limiting groove 6, which can not only ensure the sliding of the limiting block 7 along the limiting groove 6, but also strengthen the positioning of the backplane main body 2.

[0040] It should be noted that in this embodiment, the limiting block 7 is selected to be made of plastic material or rubber material, that is, the limiting block 7 itself has a certain elastic deformation ability, so as to ensure that when the limiting block 7 is adjusted and slides into the limiting space, it can be elastically closely attached to the inside of the limiting space to ensure the strengthened locking of the backplane module. Moreover, the limiting block 7 is set to be hollow, that is, by setting the middle part of the limiting block 7 to be hollow, it can be realized that while the limiting block 7 can position the backplane main body 2, it can also ensure that the limiting block 7 has a certain deformation ability.

[0041] In a specific embodiment, as Figure 6 shown, in order to ensure that the limiting block 7 does not come out of both ends of the limiting groove 6 during the sliding process of the limiting block 7 along the limiting groove 6, stop plates 13 are fixedly connected to both ends of the limiting groove 6 in the length direction, and the limiting block 7 is limited by the stop plates 13 when it slides to the corresponding position in the limiting groove 6.

[0042] As Figure 6As shown in the figure, in order to ensure that the limit block 7 can slide stably along the limit groove 6, limit stop edges 14 are fixedly connected to both ends of the limit block 7 along the depth direction of the chassis 1 parallel to each other. When the limit block 7 is slidably installed in the limit groove 6, the limit stop edges 14 are slidably clamped to the side walls of the limit groove 6, so that the setting of the limit stop edges 14 plays a role in supporting and guiding the sliding of the limit block 7. Further, the limit stop edges 14 are respectively arranged on one side close to the bottom of the limit groove 6 or one side close to the opening of the limit groove 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 stop edge 14 in the upper notch 601 is fixedly connected to the side of the limit block 7 close to the opening of the limit groove 6, and the limit stop edge 14 in the lower notch 602 is fixedly connected to the side of the limit block 7 close to the bottom of the limit groove 6, so as to avoid the anti-fooling problem in the process of assembling the limit block 7 through the setting of the limit stop edges 14.

[0043] It should be noted that installation notches are provided on the reinforcing edges 8 on both the upper and lower sides of the fixed bracket 3, and the installation notches are arranged at positions close to the limit groove 6. The length of the installation notch along the reinforcing edge 8 is greater than or equal to the width of the limit block 7, so as to realize the sliding fit installation of the limit block 7 in the limit groove 6 through the installation notch, which is convenient for assembling the limit block 7 and the limit groove 6.

[0044] Specifically, the openings of the two sliding grooves 4 inside the chassis 1 in this application are arranged opposite 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 sliding groove 4 are perpendicular to each other. The width of the sliding groove 4 is set to be greater than the width of the limit groove 6, so that when the backplane main body 2 is installed in the chassis 1, the groove of the limit groove 6 is communicated with the groove of the sliding groove 4, ensuring that the fixed bracket 3 and the limit groove 6 on the fixed bracket 3 can be accommodated in the sliding groove 4, and further adjusting the limit block 7 to be fitted and installed in the limit space, so as to realize the strengthening and fixing of the fixed bracket 3.

[0045] In this embodiment, as Figure 10 and Figure 11 shown, in this embodiment, the backplane main body 2 is selected and configured as a 4-port backplane, and the backplane main body 2 and the fixed bracket 3 are detachably connected together through a connecting member 15. Specifically, the connecting member 15 is arranged on the side of the fixed bracket 3 close to the backplane main body 2, and a connection hole 16 corresponding to the connecting member 15 is provided on the backplane main body 2; the connecting member 15 in this embodiment is selected as an I-shaped nail, and a plurality of I-shaped nails are arranged on one side of the backplane main body 2, that is, a plurality of connection holes 16 are installed along the depth direction of the chassis 1 parallel to each other, so as to realize that a plurality of backplane main bodies 2 are installed on one side of the fixed bracket 3; as Figure 2 shown, at least three 4-port backplanes are connected to one side of the fixed bracket 3 along the depth direction of the chassis 1, so as to realize the installation and positioning of a plurality of backplane main bodies 2 by one fixed bracket 3 at the same time.

[0046] AsFigure 11 As shown, since there are multiple specifications for the backplane main body 2, 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 installation structure in this embodiment applicable to the installation of a 12-port backplane at the same time, a hard disk frame 24 is provided in the chassis 1. The hard disk frame 24 in this embodiment can be compatible with a 12-port backplane or a 4-port backplane. By setting a partition on the side of the hard disk frame 24 close to the sliding groove 4, a fixing member 18 is provided on the partition. A reserved gap 17 is provided between the hard disk frame 24 and the sliding groove 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. At this time, it is not necessary to configure the 12-port backplane to be assembled with the fixing bracket 3. Only a fixing member 18 needs to be provided on the side of the hard disk frame 24 close to the sliding groove 4, and the fixing member 18 passes through the fixing hole 19 on the 12-port backplane to realize the installation and fixation of the 12-port backplane.

[0047] Furthermore, the connection hole 16 is set to be elongated. Specifically, in this embodiment, the connection hole 16 is set as a gourd hole. The length direction of the connection hole 16 is along the direction perpendicular to the depth direction of the chassis 1. Specifically, the length direction of the connection hole 16 on the 4-port backplane is along the direction perpendicular to the depth direction of the chassis 1. To realize that when the backplane main body 2 is switched from a 12-port backplane to a 4-port backplane, the fixing member 18 on the hard disk frame 24 is avoided through the elongated connection hole 16; at the same time, through holes are also opened at both ends of the backplane main body 2, and the through holes correspond to the positions of the fixing members 18 at both ends of the length direction of the hard disk frame 24. The through holes are provided to avoid the fixing members 18 at both ends.

[0048] It should be noted that since the backplane main body 2 is installed on one side of the hard disk frame 24, a plurality of LED lights are installed on the backplane main body 2, and avoidance holes 25 are opened at the positions corresponding to the LED lights on the hard disk frame 24 to avoid the LED lights.

[0049] As Figure 12 and Figure 13 shown, in order to strengthen the position stability of the backplane main body 2 installed in the chassis 1, a mounting member 20 is further provided on the backplane main body 2. Mounting holes 21 corresponding to the position of the mounting member 20 are provided on the backplane main body 2. Specifically, the mounting member 20 is selected as a hand-tightening screw. By passing the mounting member 20 through the mounting hole 21 and tightening it, the position stability between the backplane main body 2 and the hard disk frame 24 is strengthened.

[0050] In a specific embodiment, operation notches 22 are respectively provided on both side walls of the sliding groove 4 along the sliding direction. The setting of the operation notches 22 can facilitate the staff to adjust the sliding unlocking and locking of the limit block 7 along the limit groove 6.

[0051] The slide 4 in this embodiment is fixedly installed on the inner wall of the chassis 1 by 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 set at the top of the slide 4. Through the setting of the guide edge 23, the fixed bracket 3 can be easily 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 the mutual displacement to generate iron filings and cause system short circuit and damage to the machine. A stop block 5 is also set 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.

[0052] 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.

[0053] 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 direction 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 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 taken out, 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.

[0054] In this embodiment, a backplane body 2 and a fixing bracket 3 connected to one side of the backplane body 2 for fixing the backplane body 2 are provided, and the fixing bracket 3 connected to the backplane body 2 is slidably fitted in the slide groove 4 of the chassis 1, so that the backplane body 2 is installed in the chassis 1, and a limiting groove 6 is provided on one side of the fixing bracket 3, and a limiting block 7 is slidably connected in the limiting groove 6; when the fixing bracket 3 is installed in the slide groove 4, and the groove of the limiting groove 6 is connected to the groove of the slide groove 4 to form a limiting space, then the limiting block 7 is adjusted to slide close to the bottom of the slide groove 4 into the limiting space, so that the backplane body 2 is positioned by the cooperation of the limiting block 7, the limiting groove 6 and the slide groove 4; when the backplane body 2 needs to be taken out, the limiting block 7 is adjusted to be moved out of the limiting space, thereby solving the problems of complicated installation and low assembly efficiency of the hard disk backplane, and achieving the technical effect of tool-free installation and efficient disassembly and assembly of the hard disk backplane.

[0055] Further, by setting the limiting block 7 that slides left and right along the length direction of the limiting groove 6 to be hollow, and setting a deformation groove 702 on the bottom side of the limiting block 7 close to the limiting groove 6, and arranging elastic arms 703 between the deformation grooves 702, the limiting block is enabled to have a certain deformation ability. On the one hand, it can ensure that the limiting block 7 is adjusted from the first limiting hole 11 to the second limiting hole 12 along the limiting groove. On the other hand, when the deformable limiting block 7 is inserted into the limiting space, it can achieve an elastic tight fit with the limiting space, improving the positioning stability of the limiting block 7 for the backplane main body 2.

[0056] Corresponding to the above embodiment, this embodiment provides a hard disk backplane installation structure.

Specifically, the backplane main body 2 in this embodiment is selected and configured as a 12-port backplane, and a plurality of fixing holes 19 are arranged on the backplane main body 2.

The backplane main body 2 is adjusted to be placed in the reserved gap 17, and the fixing member 18 passes through the fixing holes 19 to install the backplane main body 2 in the reserved gap 17. By setting the length direction of the fixing holes 19 to be parallel to the depth direction of the chassis 1, through the above setting, the fixing holes 19 can be made compatible with the connection holes 16 on the 4-port backplane.

[0057] By setting the length direction of the fixing holes 19 on the 12-port backplane to be perpendicular to the length direction of the connection holes 16 on the 4-port backplane, it is also possible to achieve an efficient layout and utilization of the space inside the chassis 1 through the combined setting of the positions and directions of the existing components.
