Description

Technical Field

[0001] The invention relates to a chassis system, and in particular to a chassis system that can be stacked and fixed. Background Art

[0002] In servers, there is a need to stack two chassis, one as the main system chassis and the other as an expansion chassis. Generally speaking, it is common to just place one chassis on top of another chassis, but if the two chassis need to be fixed together, a fixing structure needs to be set on the outside of the chassis to fix the two chassis stacked up and down. Generally speaking, it is necessary to fix them through an external adapter or to use a locking structure on the outside of the chassis to lock and fix them. However, the use of locking parts such as external locking screws to lock the outside of the chassis is prone to falling or losing the locking parts during assembly or disassembly, and users also need to prepare additional locking tools and perform complicated locking operations. It is inconvenient to assemble and cause trouble to users, and it is worth further careful research and discussion by practitioners to improve. Summary of the invention

[0003] Therefore, an object of the present invention is to provide a stackable and fixed chassis system with good practicality.

[0004] Therefore, the stackable and fixed chassis system of the present invention includes a first chassis and a second chassis combined below the first chassis.

[0005] The first chassis includes a first box body, a first combined frame device extending from the first box body to a direction away from the first box body, and a first fixing device arranged in a first installation space of the first combined frame device.

[0006] The first combined frame device has a first substrate spaced apart from the first box, and two first mounting plates extending from two opposite sides of the first substrate toward the first box and connected to the first box. The first substrate and the first mounting plates together define a first mounting space facing the first box. The first substrate has a first opening. Each first mounting plate has two first mounting grooves spaced apart from each other.

[0007] The first fixing device has a first fixing unit close to the first mounting plate located at the bottom of the first combined frame device, and a first control unit arranged on the first fixing unit and capable of driving the first fixing unit to move up and down. The first fixing unit has a first cross bar, and two first fixing modules extending downward from two opposite sides of the first cross bar. The first fixing module corresponds to the first mounting groove of the first mounting plate located at the bottom of the first combined frame device. The first control unit has a first control module combined with the first cross bar, and a first force-applying module arranged on the first control module and passing through the first opening of the first substrate. The first force-applying module can move up and down in the first opening when force is applied, and can link the first control module to drive the first cross bar to move up and down, and make the first fixing module move up and down.

[0008] The second chassis includes a second box body, a second combined frame device extending from the second box body in a direction away from the second box body and located below the first combined frame device, and a second positioning device arranged in a second installation space of the second combined frame device.

[0009] The second combined frame device comprises a second base plate spaced apart from the second box body, and two second mounting plates extending from two opposite sides of the second base plate toward the second box body and connected to the second box body.

[0010] The second base plate and the second installation plate jointly define a second installation space facing the second box body.

[0011] The second base plate has a second opening. Each second mounting plate has two spaced second mounting grooves. The second mounting groove of the second mounting plate located at the upper side of the second combined frame device corresponds to the first mounting groove of the first mounting plate located at the lower side of the first combined frame device.

[0012] The second positioning device has a second positioning plate unit that is horizontally arranged on the second substrate and close to the second mounting plate located at the top in the second combined frame device, and two second blocking units that are spaced apart and arranged on the second positioning plate unit and correspond to the second mounting groove of the second mounting plate located at the top in the second combined frame device. The second blocking unit can block and fix the first fixing module.

[0013] When the first force-applying module is forced to move downward and links the first control module to drive the first crossbar to move downward, the first fixing module passes downward through the first installation slot and the second installation slot, and the first fixing module is buckled in the second blocking unit. At this time, the first chassis is fixed above the second chassis.

[0014] In particular, the first control module of the first control unit of the first fixing device of the first chassis has a first control body and two first connecting arms located on two opposite sides of the first control body, and the first fixing unit also has two first locking pieces for locking the first cross bar on the first connecting arms.

[0015] In particular, each first fixing module of the first fixing unit of the first fixing device has a first fixing body extending from the first cross bar toward the corresponding first mounting groove, a first guide groove passing through the first fixing body, and a first fixing member arranged on an end of the first fixing body away from the first cross bar and can be snapped into the corresponding second blocking unit. The first combined frame device also has a first guide boss module arranged on the first substrate and located in the first mounting space and close to the first mounting plate located below. The first guide boss module has two first guide bosses extending from the first substrate respectively toward the first guide groove of the first fixing module and respectively passing through the first guide grooves.

[0016] In particular, the second combined frame device of the second chassis also has a second fixed boss module arranged on the second substrate and located in the second installation space and close to the second installation plate located above, the second fixed boss module has two second fixed bosses arranged at intervals on the second substrate and extending from the second substrate to the second positioning plate unit of the second positioning device, the second positioning plate unit has a second positioning plate, and two second slide grooves that penetrate the second positioning plate and correspond to the second fixed bosses and are passed through by the second fixed bosses, each second slide groove has a second buckle end and a second non-buckle end, each second The blocking unit has a second blocking boss which is arranged on the second positioning plate and can block the first clamping piece of the corresponding first clamping module. The second positioning plate can be moved to drive the second slide groove to move between a locking position and a non-locking position relative to the second fixed boss. In the locking position, the second locking end of the second slide groove abuts against the second fixed boss and the second blocking unit is locked and combined with the first clamping piece of the first clamping module; in the non-locking position, the second non-locking end of the second slide groove abuts against the second fixed boss and the second blocking unit will not block the first clamping piece of the first clamping module.

[0017] In particular, the second substrate of the second combined frame device also has a second sliding hole, and the second positioning plate unit also has a second movable protrusion extending from the second positioning plate toward the second sliding hole of the second substrate and passing through the second sliding hole. The second movable protrusion can move relative to the second sliding hole, and applying force to move the second movable protrusion will link the movement of the second positioning plate and drive the second sliding groove to move between the locking position and the non-locking position relative to the second fixed protrusion.

[0018] In particular, the second combined frame device also has a second elastic arm module of a second positioning plate which is arranged on the second substrate and located in the second installation space and connected to the second positioning plate unit. The second elastic arm module has a second spring body combined with the second substrate, and a second elastic arm connecting the second spring body and the second positioning plate. When the second positioning plate is moved and drives the second slide groove to move to the non-clamping position, the second spring body accumulates an elastic restoring force. At this time, the second movable boss is no longer applied, and the elastic restoring force of the second spring body will cause the second elastic arm to push the second positioning plate to move toward the latching position.

[0019] In particular, each first mounting plate of the first combined frame device also has a first accommodating opening located between the first mounting grooves, and the second mounting plate of the second combined frame device also has a second accommodating opening located between the second mounting grooves, and the second accommodating opening of the second mounting plate located at the top of the second combined frame device corresponds to the first accommodating opening of the first mounting plate located at the bottom of the first combined frame device. When the first force module is forced to move downward and the first control body of the first control module is linked to drive the first cross bar to move downward, the first fixing body of the first fixing module and the first fixing member pass downward through the first mounting groove and the second mounting groove, and simultaneously the first control body passes through the first accommodating opening of the first mounting plate located at the bottom of the first combined frame device and the second accommodating opening of the second mounting plate located at the top of the second combined frame device.

[0020] In particular, the first substrate of the first combined frame device also has a first upper clamping portion and a first lower clamping portion arranged in the first opening, and the first force-applying module of the first control module has a first fixing portion arranged on the first control body of the first control module and detachably movably clamped between the first upper clamping portion and the second upper clamping portion, and a first force-applying portion arranged on the first fixing portion and passing through the first opening of the first substrate.

[0021] In particular, the first chassis also includes a first positioning device arranged in the first installation space of the first combined frame device, having a first positioning plate unit horizontally arranged on the first substrate and close to the first mounting plate located at the top of the first combined frame device, and two first blocking units spaced apart on the first positioning plate unit and corresponding to the first mounting groove of the first mounting plate located at the top of the first combined frame device.

[0022] In particular, the second chassis also includes a second fixing device arranged in the second installation space of the second combined frame device, having a second fixing unit close to the second mounting plate located at the bottom of the second combined frame device, and a second control unit arranged on the second fixing unit and capable of driving the second fixing unit to move up and down, the second fixing unit having a second cross bar, and two second fixing modules extending downward from two opposite sides of the second cross bar, the second fixing module corresponding to the second mounting slot of the second mounting plate located at the bottom of the second combined frame device, the second control unit having a second control module combined with the second cross bar, and a second force-applying module arranged on the second control module and passing through the second opening of the second substrate, the second force-applying module being able to move up and down in the second opening when force is applied and linking the second control module to drive the second cross bar to move up and down, and causing the second fixing module to move up and down.

[0023] Compared with the prior art, the stackable and fixed chassis system of the present invention is designed such that the first force-applying module of the first fixing device of the first chassis is forced to move downward and the first control module is linked to drive the first cross bar to move downward, thereby cooperating with the design that the first fixing module is made to pass downward through the first installation slot and the second installation slot of the second mounting plate located above in the second combining frame device of the second chassis, and the first fixing module is snapped into the second blocking unit, so that the first chassis can be fixed above the second chassis. The assembly action is simple and practical, and tool-free assembly operation is effectively achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0032] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The stackable and fixed chassis system of the present invention comprises a first chassis 1 and a second chassis 5 combined below the first chassis 1 .

[0033] The first chassis 1 includes a first housing 11 , a first frame device 2 extending from the first housing 11 to a direction away from the first housing 11 , and a first fixing device 3 disposed in a first installation space 23 of the first frame device 2 .

[0034] The first combined frame device 2 has a first substrate 21 spaced apart from the first box body 11, and two first mounting plates 22 extending from two opposite sides of the first substrate 21 toward the first box body 11 and connected to the first box body 11. The first substrate 21 and the first mounting plates 22 together define a first mounting space 23 facing the first box body 11. The first substrate 21 has a first opening 211. Each first mounting plate 22 has two first mounting grooves 221 spaced apart from each other.

[0035] The first fixing device 3 has a first fixing unit 31 close to the first mounting plate 22 located below in the first combined frame device 2, and a first control unit 32 arranged on the first fixing unit 31 and capable of driving the first fixing unit 31 to move up and down. The first fixing unit 31 has a first crossbar 311, and two first fixing modules 312 extending downward from two opposite sides of the first crossbar 311. The first fixing module 312 corresponds to the first mounting groove 221 of the first mounting plate 22 located below in the first combined frame device 2. The first control unit 32 has a first control module 321 combined with the first crossbar 311, and a first force module 324 arranged on the first control module 321 and passing through the first opening 211 of the first substrate 21. The first force module 324 can be moved up and down in the first opening 211 by force applied, and the first control module 321 is linked to drive the first crossbar 311 to move up and down, and the first fixing module 312 is moved up and down.

[0036] The second chassis 5 includes a second box body 51 , a second frame device 6 extending from the second box body 51 in a direction away from the second box body 51 and located below the first frame device 2 , and a second positioning device 8 disposed in a second installation space 63 of the second frame device 6 .

[0037] The second combined frame device 6 has a second substrate 61 spaced apart from the second box body 51, and two second mounting plates 62 extending from two opposite sides of the second substrate 61 toward the second box body 51 and connected to the second box body 51. The second substrate 61 and the second mounting plates 62 together define a second mounting space 63 facing the second box body 51. The second substrate 61 has a second opening 611. Each second mounting plate 62 has two spaced apart second mounting grooves 621. The second mounting groove 621 of the second mounting plate 62 located at the top in the second combined frame device 6 corresponds to the first mounting groove 221 of the first mounting plate 22 located at the bottom in the first combined frame device 2.

[0038] The second positioning device 8 has a second positioning plate unit 81 that is horizontally arranged on the second substrate 61 and close to the second mounting plate 62 located at the top in the second combined frame device 6, and two second blocking units 82 that are spaced apart and arranged on the second positioning plate unit 81 and correspond to the second mounting groove 621 of the second mounting plate 62 located at the top in the second combined frame device 6. The second blocking unit 82 can block and fix the first fixing module 312.

[0039] When the first force-applying module 324 is forced to move downward and links the first control module 321 to drive the first cross bar 311 to move downward, the first fixing module 312 passes downward through the first installation slot 221 and the second installation slot 621, and the first fixing module 312 is buckled in the second blocking unit 82. At this time, the first chassis 1 is fixed above the second chassis 5.

[0040] During assembly, the first case 11 of the first chassis 1 is first placed on the second case 51 of the second chassis 5 and the first combined frame device 2 is made to correspond to the first combined frame device 2, and the first mounting groove 221 of the first mounting plate 22 located at the bottom of the first combined frame device 2 is aligned with the second mounting groove 621 of the second mounting plate 62 located at the top of the second combined frame device 6. Then, force is applied to the first force-applying module 324 of the first control unit 32 of the first fixing device 3 and the first force-applying module 324 is moved downward, and the first control module 321 is linked to drive the first crossbar 311 of the first fastening unit 31 to move downward, and the first fastening module 312 is synchronously made to pass through the first mounting groove 221 and the second mounting groove 621 downward, and the first fastening module 312 is buckled in the second blocking unit 82. At this time, the first chassis 1 is fixed on the second chassis 5, and the assembly operation is completed. In this embodiment, the first control module 321 of the first control unit 32 of the first fixing device 3 of the first chassis 1 has a first control body 322 and two first connecting arms 323 located at two opposite sides of the first control body 322. The first fixing unit 31 also has two first locking members 316 for locking the first cross bar 311 on the first connecting arms 323. In simple terms, the first cross bar 311 is fixed to the first connecting arms 323 by using the first locking members 316. Figure 4The first connecting arm 323 is fixedly coupled to the first control module 321 as shown, but the present invention is not limited thereto. Further, in the present embodiment, each first fastening module 312 of the first fastening unit 31 of the first fixing device 3 has a first fastening body 313 extending from the first cross bar 311 to the direction of the corresponding first mounting groove 221, a first guide groove 314 penetrating the first fastening body 313, and a first fastening member 315 disposed on an end of the first fastening body 313 away from the first cross bar 311 and capable of being buckled in the corresponding second blocking unit 82. The first combined frame device 2 also has a first guide boss module 24 disposed on the first substrate 21 and located in the first mounting space 23 and close to the first mounting plate 22 located below. The first guide boss module 24 has two first guide bosses 241 extending from the first substrate 21 to the direction of the first guide groove 314 of the first fastening module 312 and passing through the first guide groove 314 respectively. That is to say, through the design of the first guiding boss 241 of the first guiding boss module 24 passing through the first guiding groove 314, it is ensured that during the downward movement of the first cross bar 311 of the first fixing unit 31 of the first fixing device 3, the first fixing body 313 and the first fixing component 315 of the first fixing module 312 of the first fixing unit 31 will be aligned with the first mounting groove 221 of the first mounting plate 22 located below in the first combined frame device 2 and the second mounting groove 621 of the second mounting plate 62 located above in the second combined frame device 6, so as to ensure that the first fixing component 315 of the first fixing module 312 passes through the first mounting groove 221 and the second mounting groove 621 downward, and the first fixing component 315 of the first fixing module 312 is as follows Figure 3 As shown, it is buckled in the second blocking unit 82.

[0041] By means of the design that the first force-applying module 324 of the first fixing device 3 of the first chassis 1 is forced to move downward and the first control module 321 is linked to drive the first cross bar 311 to move downward, the first fixing module 312 is made to pass downward through the first mounting slot 221 and the second mounting slot 621 of the second mounting plate 62 located above in the second combining frame device 6 of the second chassis 5, and the first fixing module 312 is snapped into the second blocking unit 82, so that the first chassis 1 can be fixed above the second chassis 5. The assembly action is simple and practical, and tool-free assembly operation is effectively achieved.

[0042] It should be particularly noted that, in this embodiment, the second combined frame device 6 of the second chassis 5 also has a second fixed boss module 64 disposed on the second substrate 61 and located in the second installation space 63 and close to the second installation plate 62 located above. The second fixed boss module 64 has two second fixed bosses 641 disposed at intervals on the second substrate 61 and extending from the second substrate 61 to the second positioning plate unit 81 of the second positioning device 8. The second positioning plate unit 81 has a second positioning plate 811, and two second slide grooves 812 that penetrate the second positioning plate 811 and correspond to the second fixed bosses 641 and are passed through by the second fixed bosses 641. Each second slide groove 812 has a second buckle end 813 and a second non-buckle end 814. Each second blocking unit 82 has a second blocking boss 821 disposed on the second positioning plate 811 and capable of blocking the first clamping member 315 of the corresponding first clamping module 312. The second positioning plate 811 can be moved to drive the second slide slot 812 to move between a latching position and a non-latching position relative to the second fixed boss 641. In the latching position, the second latching end 813 of the second slide slot 812 abuts against the second fixed boss 641 and the second blocking unit 82 is latched and engaged by the first fastening member 315 of the first fastening module 312; in the non-latching position, the second non-latching end 814 of the second slide slot 812 abuts against the second fixed boss 641 and the second blocking unit 82 does not block the first fastening member 315 of the first fastening module 312. In short, the second slide slot 812 of the second positioning plate unit 81 is as follows: Figure 4 The design shown in the figure is passed through by the second fixing boss 641 so that the second positioning plate 811 can be moved to drive the second slide 812 to move between the snap position and the non-snap position relative to the second fixing boss 641. During the assembly process, since the default position of the second positioning plate 811 and the second slide 812 is at the snap position in this embodiment, but not limited to this, it is necessary to first move the second positioning plate 811 to drive the second slide 812 to move to the non-snap position relative to the second fixing boss 641, and then move the first cross bar 311 of the first fixing unit 31 of the first fixing device 3 of the first chassis 1 downward and drive the first fixing member 315 of the first fixing module 312 to pass downward through the first mounting slot 221 and the second mounting slot 621 of the second mounting plate 62 located above in the second combined frame device 6 of the second chassis 5 and extend to the desired position. Finally, as long as the second positioning plate 811 is moved to drive the second slide groove 812 to move to the locking position relative to the second fixing protrusion 641, the first locking member 315 of the first locking module 312 is as follows: Figure 4As shown, the second blocking protrusion 821 is locked in the second blocking unit 82, but the assembly method is not limited thereto.

[0043] Here, it should be explained that, in the present embodiment, the second substrate 61 of the second combined frame device 6 also has a second sliding hole 612. The second positioning plate unit 81 also has a second movable boss 815 extending from the second positioning plate 811 toward the second sliding hole 612 of the second substrate 61 and passing through the second sliding hole 612. The second movable boss 815 can move relative to the second sliding hole 612. Applying force to move the second movable boss 815 will link the movement of the second positioning plate 811 and drive the second slide groove 812 to move between the snap position and the non-snap position relative to the second fixed boss 641, but not limited to this. In simple terms, the second movable boss 815 of the second positioning plate unit 81 is used as follows Figure 6 The design of the second sliding hole 612 penetrating the second combined frame device 6 as shown can facilitate the user to directly apply force to move the second movable boss 815 to move left and right, thereby linking the second positioning plate 811 located in the second installation space 63 of the second combined frame device 6 to move left and right, and driving the second slide groove 812 to move between the snap position and the non-snap position relative to the second fixed boss 641, but not limited to this. In addition, it should be particularly noted that in this embodiment, the second combined frame device 6 also has a second elastic arm module 65 of the second positioning plate 811 disposed on the second substrate 61 and located in the second installation space 63, and connected to the second positioning plate unit 81. The second elastic arm module 65 has a second spring body 651 combined with the second substrate 61, and a second elastic arm 652 connecting the second spring body 651 and the second positioning plate 811. When the second positioning plate 811 is moved to drive the second slide slot 812 to move to the non-locking position, the second spring body 651 accumulates an elastic restoring force. At this time, the second movable boss 815 is no longer applied, and the elastic restoring force of the second spring body 651 causes the second elastic arm 652 to push the second positioning plate 811 to move toward the locking position. In this embodiment, the default position of the second positioning plate 811 and the second slide slot 812 is at the locking position, but is not limited thereto. During the process of the first cross bar 311 of the first fastening unit 31 of the first fixing device 3 of the first chassis 1 moving downward and driving the first fastening member 315 of the first fastening module 312 to pass downward through the first mounting groove 221 and the second mounting groove 621 of the second mounting plate 62 located above in the second combining frame device 6 of the second chassis 5, the first fastening member 315 will push the second blocking protrusion 821 to move and drive the second positioning plate 811 and the second sliding groove 812 to move to the non-fastening position, and the second elastic arm 652 of the second elastic arm module 65 is as shown in FIG. Figure 4 The design pattern of connecting the second spring body 651 and the second positioning plate 811 as shown, when the second positioning plate 811 is moved to drive the second slide slot 812 to move to the non-locking position, the second spring body 651 accumulates the elastic restoring force. When the first clamping member 315 moves downward to not push the second blocking protrusion 821, it means that the first clamping member 315 has reached the desired position. At this time, the elastic restoring force of the second spring body 651 causes the second elastic arm 652 to push the second positioning plate 811 to move in the direction of the locking position, and causes the second blocking protrusion 821 of the second blocking unit 82 to be as shown. Figure 4 As shown, the first clamping member 315 is blocked and fixed.

[0044] Incidentally, in this embodiment, each first mounting plate 22 of the first combined frame device 2 also has a first receiving opening 222 located between the first mounting grooves 221. The second mounting plate 62 of the second combined frame device 6 also has a second receiving opening 622 located between the second mounting grooves 621. The second receiving opening 622 of the second mounting plate 62 located at the top of the second combined frame device 6 corresponds to the first receiving opening 222 of the first mounting plate 22 located at the bottom of the first combined frame device 2. When the first force-applying module 324 is forced to move downward and the first control body 322 of the first control module 321 is linked to drive the first cross bar 311 to move downward, the first fixing body 313 of the first fixing module 312 and the fixing member pass downward through the first mounting groove 221 and the second mounting groove 621, and simultaneously make the first control body 322 pass through the first accommodating opening 222 of the first mounting plate 22 located at the bottom in the first combined frame device 2 and the second accommodating opening 622 of the second mounting plate 62 located at the top in the second combined frame device 6, but not limited to this.

[0045] In addition, it should be noted that, in the present embodiment, the first substrate 21 of the first combined frame device 2 also has a first upper clamping portion 212 disposed in the first opening 211, and a first lower clamping portion 213. The first force-applying module 324 of the first control module 321 has a first fixing portion 325 disposed on the first control body 322 of the first control module 321 and detachably fixed to the first upper clamping portion 212 and the second upper clamping portion, and a first force-applying portion 326 disposed on the first fixing portion 325 and passing through the first opening 211 of the first substrate 21. In simple terms, the first fixing portion 325 of the first force-applying module 324 of the first control module 321 can be as Figure 5 As shown, it is fixed to the first lower clamping portion 213, but the present invention is not limited thereto.

[0046] In particular, in this embodiment, the first chassis 1 further includes a first positioning device 4 disposed in the first installation space 23 of the first combined frame device 2. The first positioning device 4 has a first positioning plate unit 41 disposed transversely on the first substrate 21 and close to the first mounting plate 22 located at the top of the first combined frame device 2, and two first blocking units 42 disposed at intervals on the first positioning plate unit 41 and corresponding to the first mounting groove 221 of the first mounting plate 22 located at the top of the first combined frame device 2. In short, the first chassis 1 also has the first positioning plate unit 41.
