[0068] The present application provides a hard disk backboard assembly, which will be described in detail below with reference to the accompanying drawings.

[0069] Referring to FIG. 1, a structure schematic diagram of a support of a hard disk backboard assembly provided by an embodiment of the present application is shown, referring to FIG. 2, an assembly schematic diagram of a twenty-four-port backboard and the support provided by an embodiment of the present application is shown, referring to FIG. 3, a structure schematic diagram of a twelve-port backboard provided by an embodiment of the present application is shown, referring to FIG. 4, a structure schematic diagram of a four-port backboard provided by an embodiment of the present application is shown, referring to FIG. 5, a structure schematic diagram of a detachable hand-turning module provided by an embodiment of the present application is shown, and referring to FIG. 6, a partial structure schematic diagram of the support provided by an embodiment of the present application is shown.

[0070] As shown in FIGS. 1 to 2, the present application provides a hard disk backboard assembly, which comprises a support 1 and at least one backboard 2 mounted on the support 1; a plurality of hand-turning modules are arranged on the side of the support 1 away from the backboard 2, and at least part of the hand-turning modules are arranged through the support 1; the backboard 2 is provided with a fixing nut 21 at the corresponding position of the hand-turning module, and one fixing nut 21 is connected with one hand-turning module; wherein the hand-turning module comprises a fixed hand-turning module 3 and a detachable hand-turning module 4, the fixed hand-turning module 3 is fixedly connected with the support 1, and the detachable hand-turning module 4 is detachably connected with the support 1.

[0071] In the embodiment of the present application, the hand-turning module and the fixing nut 21 are arranged at the corresponding positions of the bracket 1 and the backboard 2, respectively. In this way, during the disassembly and assembly of the hard disk backboard assembly, the connection or disconnection of the hand-turning module and the fixing nut 21 can be achieved by manually rotating the hand-turning module, that is, the disassembly and assembly of the hard disk backboard assembly can be completed without the aid of tools, which is beneficial to improve the convenience of disassembly and assembly and maintenance of the hard disk backboard assembly. In addition, the fixed hand-turning module 3 and the detachable hand-turning module 4 are arranged, so that when the fixed hand-turning module 3 cannot meet the fixing requirements due to the setting of backboards 2 of different specifications, the detachable hand-turning module 4 can be added to fix the backboard 2, thereby improving the versatility of the bracket 1 while reducing the number of fixed hand-turning modules 3, which is beneficial to reduce the production cost of the hard disk backboard assembly.

[0072] It should be noted that the number and specifications of the backboard 2 installed in the bracket 1 are not limited in the embodiment of the present application, and those skilled in the art can adjust them according to actual needs. It can be understood that the bracket 1 of the embodiment of the present application can meet the configuration requirements of various backboards 2 and has high versatility. As shown in FIGS. 1-4, in one embodiment, the bracket 1 can at least adapt to a conventional four-port backboard, a twelve-port backboard and a twenty-four-port backboard. Specifically, the four-port backboard, the twelve-port backboard and the twenty-four-port backboard are arranged horizontally, that is, the four insertion ports of the four-port backboard are arranged in one row and four columns, the twelve insertion ports of the twelve-port backboard are arranged in three rows and four columns, and the twenty-four insertion ports of the twenty-four-port backboard 2 are arranged in six rows and four columns. In addition, the bracket 1 is also provided with a plurality of third through holes 15, and the plurality of third through holes 15 are arrayed along the second direction Y and the third direction Z, so as to avoid the electronic components near the side of the bracket 1 close to the backboard 2. For the bracket 1 which can at least meet the installation of the twenty-four-port backboard, the bracket 1 is adapted to the outer dimensions of the twenty-four-port backboard, and the bracket 1 needs to be provided with at least six rows and four columns, a total of twenty-four third through holes 15. It can be understood that adjacent third through holes 15 can be combined.

[0073] Based on the above application scenarios, four fixed hand-turning modules 3 can be arranged to meet the fixed reliability. Specifically, two fixed hand-turning modules 3 are arranged between the third through holes 15 in the first and second columns and the third and fourth columns of the second row, and the other two fixed hand-turning modules 3 are arranged between the third through holes 15 in the first and second columns and the third and fourth columns of the fifth row. This arrangement not only reduces the number of fixed hand-turning modules 3, but also meets the mainstream configuration, i.e., twenty-four-port backboard and double-twelve-port backboard. In addition, when multiple, such as three, four-port backboards need to be configured, four detachable hand-turning modules 4 can be added. Specifically, one detachable hand-turning module 4 is installed between the third through holes 15 in the first and second columns and the third and fourth columns of the first row, and between the third through holes 15 in the first and second columns and the third and fourth columns of the third row, respectively. In this way, the reliable fixation of three four-port backboards can be achieved through the combination of fixed hand-turning modules 3 and detachable hand-turning modules 4. It can be understood that, in order to improve the stress uniformity of the backboard 2, the hand-turning modules (including fixed hand-turning modules 3 and detachable hand-turning modules 4) are usually arranged between adjacent two third through holes 15. For the backboard 2 designed transversely in FIGS. 2-4, the hand-turning modules on the support 1 are usually arranged between adjacent two third through holes 15 in the same row, and the specific number and position of the hand-turning modules are not limited here, and can be adjusted according to actual needs by those skilled in the art.

[0074] It should be noted that the fixed hand-turning module 3 of the embodiment of the present application can select the existing hand-turning screw. In addition, the first direction X of the embodiment of the present application refers to the thickness direction of the support 1, the second direction Y refers to the width direction of the support 1, and the third direction Z refers to the length direction of the support 1, wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0075] In some optional embodiments of the present application, as shown in FIGS. 5-6, the thickness direction of the support 1 is the first direction X, and the support 1 comprises a guide groove 11 and a first through hole 12, the guide groove 11 is arranged on the side of the support 1 away from the backboard 2, and the first through hole 12 is located within the projection range of the guide groove 11 along the first direction X; the detachable hand-turning module 4 comprises a base 41 and an elastic protruding portion 432 connected to the base 41, the base 41 is slidingly connected to the guide groove 11, and in the case that the base 41 slides to a first target position, the elastic protruding portion 432 protrudes into the first through hole 12 to limit the base 41.

[0076] In the embodiment of the present application, since the guide groove 11 is arranged, in the process of installing the detachable hand-turning mold set 4 to the support 1, one end of the base 41 can be matched with the guide groove 11 first, and then the base 41 is slid along the guide groove 11 to the first target position, so that the alignment and installation of the support 1 and the detachable hand-turning mold set 4 are completed. Since the elastic protruding part 432 is arranged, when the base 41 is slid to the first target position, the elastic protruding part 432 can protrude from the first through hole 12, so that the base 41 is reliably limited, to facilitate the subsequent installation of the detachable hand-turning mold set 4 and the fixing nut 21 of the back plate 2. The detachable connection structure is simple and reliable, and does not need to be assisted by work, which not only can reduce the production cost of the support 1, but also can improve the production and maintenance efficiency of the support 1. It should be noted that the first target position of the embodiment of the present application refers to the position of the detachable hand-turning mold set 4 and the support 1 after the complete assembly.

[0077] In some optional embodiments of the present application, the support 1 further comprises a second through hole 13, and the second through hole 13 is located in the projection range of the guide groove 11 along the first direction X; the detachable hand-turning mold set 4 further comprises a hand-turning screw 42, and the hand-turning screw 42 is telescopically connected to the base 41. In the case that the base 41 is slid to the first target position, the hand-turning screw 42 can be arranged through the second through hole 13 to be connected with the fixing nut 21. In this way, since the hand-turning screw 42 is arranged, and the support 1 is provided with the second through hole 13 at the corresponding position of the hand-turning screw 42. In the case that the base 41 is slid to the first target position, the hand-turning screw 42 can be arranged through the second through hole 13 to be connected with the fixing nut 21, so that the reliable fixing of the support 1 and the back plate 2 can be realized.

[0078] It should be noted that the hand-turning screw 42 of the embodiment of the present application can be a spring screw in the prior art, that is, when not in use, the hand-turning screw 42 does not protrude relative to the base 41, so that the disassembly and assembly of the detachable hand-turning mold set 4 can be facilitated; when in use, the hand-turning screw 42 can protrude relative to the base 41, so that the connection between the hand-turning screw 42 and the fixing nut 21 can be facilitated. In addition, in order to improve the rotation convenience of the hand-turning screw 42, a rhombic hand-turning screw can be selected.

[0079] In some optional embodiments of the present application, the support 1 further comprises a stop column 14, and the stop column 14 is arranged at one end of the guide groove 11. In the case that the base 41 is slid to the first target position, the stop column 14 at least partially abuts against the base 41 to limit the base 41. In this way, by arranging the stop column 14 and by the at least partial abutment between the stop column 14 and the base 41, the sliding of the base 41 can be limited, so that the elastic protruding part 432 and the first through hole 12 are better matched and limited, which is beneficial to improve the installation accuracy and convenience of the detachable hand-turning mold set 4.

[0080] It should be noted that in one of the embodiments, the guide groove 11 is composed of two L-shaped limiting plates. Specifically, the two L-shaped limiting plates are arranged opposite to each other along the third direction Z on the side of the support 1 away from the back plate 2, and the two L-shaped limiting plates and the support 1 form the guide groove 11. The process of assembling the detachable hand turning mold set 4 to the support 1 is roughly as follows: first, the base 41 is attached to the support 1, at this time, the elastic protruding part 432 is in a compressed state; then, the base 41 is slid along the guide groove 11 to make the base 41 abut against the stop column 14, at this time, the elastic protruding part 432 is in an extended state and located in the first through hole 12, thus, the tool-free assembly of the detachable hand turning mold set 4 and the support 1 is completed.

[0081] In some optional embodiments of the present application, the base 41 is provided with a first mounting hole 411, and in the case that the base 41 slides to the first target position, the first mounting hole 411 is opposite to the position of the first through hole 12; the detachable hand turning mold set 4 further includes a spring sheet 43, the spring sheet 43 is fixedly connected to the side of the base 41 away from the support 1, the spring sheet 43 is provided with a connecting hole 431 at the corresponding position of the first mounting hole 411, and the elastic protruding part 432 is arranged in the connecting hole 431 and at least part of the elastic protruding part 432 protrudes from the first mounting hole 411.

[0082] In actual application, due to the different roles of the base 41 and the spring sheet 43, the base 41 mainly serves to support and connect other components, and thus requires greater rigidity. The spring sheet 43 should have a certain deformation ability, and thus requires less rigidity. Therefore, the embodiments of the present application set the spring sheet 43 and the base 41 separately and connect them together to meet the above requirements. Specifically, by arranging the connecting hole 431 at the corresponding position of the first mounting hole 411, the elastic protruding part 432 arranged in the connecting hole 431 can protrude from the first mounting hole 411 to extend into the first through hole 12 after the detachable hand turning mold set 4 is mounted to the support 1, thereby achieving the limiting effect.

[0083] It should be noted that the spring sheet 43 can be an integral structure, thereby improving the connection strength between the elastic protruding part 432 and the wall of the connecting hole 431, so that the spring sheet 43 still has good elasticity after being used for many times. In one of the embodiments, the spring sheet 43 and the base 41 are connected in a rivet-free manner. Specifically, the spring sheet 43 is provided with two rivet holes 433, and the two rivet holes 433 are respectively located on the two sides of the connecting hole 431; correspondingly, the base 41 is provided with a rivet column 413 at the corresponding position of the rivet hole 433, and the rivet column 413 and the rivet hole 433 are connected in cooperation, thereby realizing the reliable connection between the spring sheet 43 and the base 41. In addition, the base 41 is further provided with a second mounting hole 412, and the hand turning screw 42 is riveted to the second mounting hole 412, thereby making the hand turning screw 42 and the base 41 reliably fixed together.

[0084] In actual application, the performance of the elastic protruding part 432 determines the service life of the detachable hand-turning mold set 4. Based on this, in some optional embodiments of the present application, the height of the elastic protruding part 432 protruding from the base 41 along the first direction X needs to meet 1 / 3-1 / 2 of the thickness of the base 41 along the first direction X. In this way, not only can the elastic protruding part 432 play a role of stop, but also can ensure that the elastic protruding part 432 still has good elasticity after being used for many times, which is beneficial to improve the service life of the detachable hand-turning mold set 4 and reduce the production and maintenance cost of the support 1. It should be noted that the above requirement for the height of the elastic protruding part 432 is in the case that the detachable hand-turning mold set 4 is not used or has been installed in place, that is, the elastic protruding part 432 is not deformed.

[0094] In summary, the hard disk backboard assembly provided by the embodiments of the present application has at least the following advantages:

[0095] In the embodiments of the present application, the hand turning module and the fixed nut are arranged at the corresponding positions of the bracket and the backboard. Therefore, during the disassembly and assembly of the hard disk backboard assembly, the connection or disconnection between the hand turning module and the fixed nut can be achieved by manually rotating the hand turning module, i.e., the disassembly and assembly of the hard disk backboard assembly can be completed without the aid of tools, which is beneficial to improve the convenience of disassembly and assembly of the hard disk backboard assembly. In addition, since the fixed hand turning module and the detachable hand turning module are arranged, when the fixed hand turning module cannot meet the fixing requirements due to the arrangement of different specifications of backboards, the detachable hand turning module can be added to fix the backboard, so as to improve the universality of the bracket while reducing the number of fixed hand turning modules, which is beneficial to reduce the production cost of the hard disk backboard assembly.

[0096] Referring to FIGS. 7-8, a structural schematic diagram of a case provided by an embodiment of the present application is shown, referring to FIGS. 9-10, a structural schematic diagram of a slide rail provided by an embodiment of the present application is shown, and referring to FIG. 11, a structural schematic diagram of a hand turning column pin provided by an embodiment of the present application is shown.

[0097] As shown in FIGS. 7-8, the present application further provides a case, which comprises: a case body 5, the case body 5 having a second direction Y and a third direction Z perpendicular to each other; two groups of slide rails 6, the two groups of slide rails 6 being arranged in the case body 5 along the third direction Z; and the hard disk backboard assembly of any one of the above embodiments, the hard disk backboard assembly being arranged between the two groups of slide rails 6 and being slidably connected to the slide rails 6 along the second direction Y.

[0098] In the embodiments of the present application, since the slide rail 6 is arranged and the hard disk backboard assembly is slidably connected to the slide rail 6, the disassembly and assembly of the hard disk backboard assembly and the case body 5 can be achieved by a simple pushing and pulling action without the aid of tools, which is beneficial to improve the disassembly and assembly efficiency and convenience of the hard disk backboard assembly and the case body 5.

[0099] It should be noted that in the embodiments of the present application, the structure of the hard disk backboard assembly is the same as that of the hard disk backboard assembly of any of the above embodiments, and the beneficial effects are similar, which will not be repeated here.

[0100] In some optional embodiments of the present application, as shown in FIGS. 9-10, the box 5 has an opening 51, and the slide rail 6 includes: two slide plates 61 spaced apart along the first direction X, the first direction X being perpendicular to the second direction Y and the third direction Z respectively; each of the two slide plates 61 is provided with a first bending portion 611 on the side close to the opening 51, and the two first bending portions 611 extend in directions away from each other to avoid the hard disk backboard assembly; each of the two slide plates 61 is provided with a second bending portion 612 on the side away from the opening 51, and the two second bending portions 612 extend in directions close to each other to limit the hard disk backboard assembly.

[0101] In actual application, the hard disk backboard assembly is pushed into the box 5 from the opening 51, and by setting the first bending portions 611 away from each other on the side of the slide rail 6 close to the opening 51, i.e., the starting end of the slide rail 6 is expanded, the hard disk backboard assembly can be avoided at the beginning of installation, and damage caused by the collision between the electronic components of the backboard 2 and the slide rail 6 can be effectively avoided. By setting the second bending portions 612 close to each other on the side of the slide rail 6 away from the opening 51, i.e., the end of the slide rail 6 is contracted, the hard disk backboard assembly can be limited, and damage caused by the collision between the hard disk backboard assembly and the box 5 can be avoided.

[0102] In actual application, due to the limited space of the case, the assembly space of the hard disk backboard assembly is very limited, which will lead to the risk of assembly collision during the assembly of the hard disk backboard assembly and the slide rail 6. Based on this, in some optional embodiments of the present application, the slide plate 61 close to the backboard 2 is a first slide plate 63, and the slide plate 61 away from the backboard 2 is a second slide plate 64; the distance between the first slide plate 63 and the opening 51 along the second direction Y is greater than the distance between the second slide plate 64 and the opening 51 along the second direction Y, so that the hard disk backboard assembly first abuts against the second slide plate 64. In this way, during the assembly of the hard disk backboard assembly to the slide rail 6, the bracket 1 of the hard disk backboard assembly can first abut against the second slide plate 64. On the one hand, it can avoid the collision between the first slide plate 63 and the electronic components on the backboard 2 when the backboard 2 first abuts against the first slide plate 63, and on the other hand, it can facilitate the precise cooperation between the hard disk backboard assembly and the slide rail 6.

[0103] It should be noted that the embodiments of the present application do not limit the difference between the distance of the first slide plate 63 from the opening 51 along the second direction Y and the distance of the second slide plate 64 from the opening 51 along the second direction Y, i.e., the difference between the lengths of the first slide plate 63 and the second slide plate 64 along the second direction Y, and those skilled in the art can adjust it according to actual needs. In one of the embodiments, it is detected that when the difference between the distance of the first slide plate 63 from the opening 51 along the second direction Y and the distance of the second slide plate 64 from the opening 51 along the second direction Y is 15 mm, the worker can take the first bending part 611 of the second slide plate 64 as a positioning fulcrum, make the hard disk backboard assembly lean against the first bending part 611 of the second slide plate 64 at an angle of 10°-20°, and then send it into the slide rail 6 along the second direction Y until the hard disk backboard assembly is completely pushed into the box body 5. In this process, the electronic components on the backboard 2 will not collide with the slide rail 6.

[0104] In some optional embodiments of the present application, the slide rail 6 further comprises a fixed plate 62 fixedly connected with the box body 5, and the fixed plate 62 is provided with a clamping groove 621 at one end close to the opening 51.

[0105] In the embodiments of the present application, the clamping groove 621 and the spring dowel 110 are arranged and clamped with each other. In this way, on the one hand, this connection structure is simple and reliable, and does not need to rely on tools, which can improve the assembly efficiency and convenience of the hard disk backboard assembly and the slide rail 6. On the other hand, by arranging the clamping groove 621 and the spring dowel 110 that are matched with each other, it can be prevented from being loosened due to vibration or external force, which is beneficial to improve the connection stability of the hard disk backboard assembly and the slide rail 6.

[0106] It should be noted that the second target position of the embodiments of the present application refers to the position of the hard disk backboard assembly when it is assembled with the slide rail 6. The slide rail 6 can further comprise a slide rail bracket 65 arranged on the side of the fixed plate 62 away from the center of the box body 5 and fixedly connected with the fixed plate 62. By fixing the slide rail bracket 65 with the box body 5, the reliable fixation of the slide rail 6 can be achieved. The process of assembling the hard disk backboard assembly to the slide rail 6 is roughly as follows: first, abut the bracket 1 of the hard disk backboard assembly with the first bending part of the second slide plate 64; then, send the hard disk backboard assembly into the slide rail 6 along the second direction Y until it is completely pushed in, and at the same time, the clamping groove 621 of the slide rail 6 is clamped with the spring dowel 110 of the bracket 1; finally, rotate the hand turning column pin 111 to be inserted into the pin hole 622, and thus the tool-free installation of the hard disk backboard assembly and the slide rail 6 is completed.
