Description

Technical Field

[0001] The present invention relates to a server chassis and a server device, particularly a server chassis comprising two trays that can be independently flipped, and a server device comprising the server chassis. Background Technology

[0002] With the development of high-performance computing and artificial intelligence applications, the density of internal components in servers is increasing, including graphics processing units (GPUs), high-speed storage devices (such as U.2 solid-state drives), and long power supplies (PSUs) and power distribution boards (PDBs) that support high power consumption. In order to ensure structural stability and signal integrity, traditional server chassis are usually designed to stack and install various functional modules in a fixed manner inside the chassis.

[0003] However, this fixed design of server chassis often faces the challenge of insufficient operating space during production line assembly or subsequent server room maintenance. For example, while placing a shorter U.2 SSD below a longer GPU facilitates GPU maintenance, it makes assembling the U.2 module's backplane and plugging and unplugging the cables connected to it difficult. Furthermore, installing a power distribution module with a long power supply (e.g., approximately 265 mm in length) in the lower part of the chassis occupies the assembly space required for the motherboard. Moving the motherboard upwards not only reduces the space available for modules above the chassis but also makes power cable routing difficult.

[0004] To address this issue, the industry often employs pull-out or detachable upper module structures. However, pull-out structures require additional slide rails and guide components, increasing the number of parts and cost. Detachable structures, on the other hand, require the removal of cables during operation, making assembly cumbersome and necessitating repeated cable plugging and unplugging during equipment maintenance, thus increasing the risk of connector wear and tear.

[0005] Therefore, designing a server chassis with a simple structure to improve the ease of disassembly, assembly, and maintenance of internal components is one of the problems that R&D personnel should solve. Summary of the Invention

[0006] The present invention provides a server chassis with a simple structure, thereby improving the convenience of disassembling, assembling and maintaining internal components of the server device.

[0007] An embodiment of the present invention discloses a server chassis for mounting a motherboard, comprising a housing, a front tray, and a rear tray. The housing includes a bottom plate, a back plate, and two side plates. The back plate is connected to the bottom plate. The two side plates are respectively connected to opposite sides of the bottom plate. The bottom plate, back plate, and two side plates together surround an accommodating space. The accommodating space has an upper space and a lower space. The upper space is farther from the bottom plate than the lower space. The lower space is used for mounting the motherboard. The front tray is pivotally located in the upper space. The rear tray is pivotally located in the upper space and is situated between the back plate and the front tray.

[0008] Another embodiment of the present invention discloses a server device including a server chassis, a motherboard, a graphics processor, a hard disk module, a power distribution module, and a power supply module. The server chassis includes a housing, a front tray, and a rear tray. The housing includes a bottom plate, a back plate, and two side plates. The back plate is connected to the bottom plate. The two side plates are respectively connected to opposite sides of the bottom plate. The bottom plate, back plate, and two side plates together surround an accommodating space. The accommodating space has an upper space and a lower space. The upper space is farther from the bottom plate than the lower space. The lower space is used to mount the motherboard. The front tray is pivotally located in the upper space. The rear tray is pivotally located in the upper space and is situated between the back plate and the front tray. The motherboard is disposed on the bottom plate. The graphics processor is located in the lower space. The graphics processor is farther from the back plate than the motherboard and is partially located below the front tray. The hard disk module is detachably disposed on the front tray. The hard disk module and the front tray are pivotable relative to the housing. The power distribution module is detachably mounted on the rear tray. The power distribution module and the rear tray are pivotable relative to the housing. The power supply module is electrically connected to the side of the power distribution module closest to the back panel. The hard drive module and the power distribution module are electrically connected to the motherboard.

[0009] According to the server device of the above embodiment, since the front and rear trays located in the upper space of the server chassis can pivot independently, when maintenance or cable connection work is required on components such as the motherboard or graphics processing module located in the upper and lower spaces of the chassis, it is not necessary to remove the trays and modules on them in the upper space of the chassis, nor is it necessary to disconnect any connecting cables. Simply by flipping the front and rear trays, the motherboard and various functional modules located in the lower space can be exposed. In this way, after flipping the front and rear trays, an unobstructed working area inside the server chassis can be provided without complicated disassembly and assembly steps, thereby improving the convenience and efficiency of disassembly and assembly of the motherboard and various functional modules and cable management, and reducing the risk of operator error.

Detailed Implementation

[0020] Please see Figure 1 and Figure 2 . Figure 1 A perspective view of a server chassis according to an embodiment of the present invention is shown. Figure 2 It shows Figure 1 A partial exploded view of the server chassis.

[0021] In this embodiment, the server chassis 10 is used to house a motherboard 20 (please refer to the previous section). Figure 7 The server chassis 10 can be used in applications such as high-performance computing servers, artificial intelligence servers, or cloud servers, but this invention is not limited thereto. The height of the server chassis 10 can be 5U, but this invention is not limited thereto.

[0022] The server chassis 10 includes a housing 11, a front tray 12, and a rear tray 13. The housing 11 includes a base plate 111, two side plates 113, a front panel 115, and a back panel 117. The two side plates 113 are respectively connected to opposite sides of the base plate 111. The front panel 115 is respectively connected to opposite sides of the two side plates 113. The back panel 117 is connected to one side of the base plate 111 and to opposite sides of the two side plates 113. Specifically, the front panel 115 is located on one side of the side plates 113, and the back panel 117 is located on the other side of the side plates 113.

[0023] The base plate 111, two side plates 113, front plate 115, and back plate 117 together form an accommodating space 119. The accommodating space 119 has an upper space 1191 and a lower space 1192. The upper space 1191 is further away from the base plate 111 than the lower space 1192. The lower space 1192 is used for mounting the motherboard 20 (please refer to the following for now). Figure 7 ).

[0024] The front tray 12 is pivotally located in the upper space 1191. The rear tray 13 is pivotally located in the upper space 1191 and is situated between the back panel 117 and the front tray 12.

[0025] Please see Figures 3 to 6 . Figure 3 It shows Figure 1 An exploded view of the front tray of the server chassis. Figure 4 It shows Figure 1 An exploded view of the rear tray of the server chassis. Figure 5 It shows Figure 1 A side sectional view of the front and rear trays of the server chassis in the usage position. Figure 6 It shows Figure 1 A side sectional view of the front and rear trays of the server chassis in the flip position.

[0026] like Figure 5As shown, the front tray 12 has a first pivot side 121 near the back panel 117. The rear tray 13 has a second pivot side 131 away from the back panel 117. When the front tray 12 and the rear tray 13 are both parallel to the bottom plate 111 and are in a flat position, the first pivot side 121 and the second pivot side 131 are adjacent to each other.

[0027] like Figure 3 , Figure 5 and Figure 6 As shown, the front tray 12 also includes two first rotating brackets 122. The two first rotating brackets 122 are respectively disposed at opposite ends of the two first pivot sides 121 of the front tray 12 by a plurality of fasteners 15. The first pivot member 123 passes through the first rotating brackets 122 and through the side plate 113, so that the front tray 12 can pivot relative to the housing 11 to be in a flat or upright state.

[0028] like Figure 4 , Figure 5 and Figure 6 As shown, the rear tray 13 also includes two second rotating supports 132. The two second rotating supports 132 are respectively disposed at opposite ends of the two second pivot sides 131 of the rear tray 13 by a plurality of fasteners 15. The second pivot members 133 pass through the second rotating supports 132 and through the side plate 113, so that the rear tray 13 can pivot relative to the housing 11 to be in a flat or upright state.

[0029] In this embodiment, the front tray 12 and rear tray 13, which are laid flat, are positioned from their respective usage positions (e.g., ...). Figure 5 Pivot to the flipped position (as shown) Figure 6 (As shown) The angle of the upright position can be 90°. When the front tray 12 and the rear tray 13 are in the flip position, the accommodating space 119 of the server chassis 10 is not obstructed by the front tray 12 and the rear tray 13, making it convenient for the operator to perform the work procedures inside the server chassis 10.

[0030] The first pivot member 123 and the second pivot member 133 may each include a guide protrusion (not shown). On the side of each of the corresponding two side plates 113 facing the receiving space 119, each may have a guide groove (not shown) corresponding to the guide protrusion. The guide protrusion is slidably located in the guide groove. In this way, the guide protrusion and guide groove can restrict the rotation of the front tray 12 and the rear tray 13 along the pivot path and prevent the front tray 12 and the rear tray 13 from shifting during flipping.

[0031] In this embodiment, the front tray 12 may include two first positioning protrusions 124. The first positioning protrusions 124 may include, but are not limited to, plungers. Each of the two side plates 113 may include a first use positioning hole 1131 and a first flip positioning hole 1132. The first positioning protrusions 124 are detachably located in the first use positioning hole 1131 or the first flip positioning hole 1132. When the front tray 12 pivots from the use position to the flip position, it is positioned by the first positioning protrusions 124 and the first flip positioning hole 1132 to fix the front tray 12 in the flip position. When the front tray 12 pivots from the flip position to the use position, it is positioned by the first positioning protrusions 124 and the first use positioning hole 1131 to fix the front tray 12 in the use position.

[0032] In this embodiment, the rear tray 13 may include two second positioning protrusions 134. The second positioning protrusions 134 may include, but are not limited to, plungers. Each of the two side plates 113 may include a second use positioning hole 1133 and a second flip positioning hole 1134. The second positioning protrusions 134 are detachably located in the second use positioning hole 1133 or the second flip positioning hole 1134. When the rear tray 13 pivots from the use position to the flip position, the second positioning protrusions 134 are positioned with the second flip positioning hole 1134 to fix the rear tray 13 in the flip position. When the rear tray 13 pivots from the flip position to the use position, the second positioning protrusions 134 are positioned with the second use positioning hole 1133 to fix the rear tray 13 in the use position.

[0033] The first pivot member 123 and the second pivot member 133 may have the same or different structures, such as pivots or hinges, but the present invention is not limited thereto. In this embodiment, both the first pivot member 123 and the second pivot member 133 may be pivots, but the present invention is not limited thereto. In other embodiments, both the first pivot member 123 and the second pivot member 133 may be damped hinges. In other embodiments, one of the first pivot member 123 and the second pivot member 133 may be a pivot, and the other may be a damped hinge. This damped hinge structure allows the front tray 12 or the rear tray 13 to hover at various angles within a 90° angle range between the use position and the flip position during the flipping process, thereby providing better operational safety and control, and is especially suitable for trays carrying heavy modules.

[0034] like Figure 3 As shown, the front tray 12 may also include two third positioning protrusions 125. The third positioning protrusions 125 may include, but are not limited to, plungers. Each of the two side plates 113 may include a third positioning hole 1138. The third positioning protrusions 125 are detachably located in the third positioning holes 1138 to more securely position the front tray 12 in the use position.

[0035] like Figure 4 As shown, the rear tray 13 may also include two fourth positioning protrusions 135. The fourth positioning protrusions 135 may include, but are not limited to, plungers. Each of the two side plates 113 may include a fourth positioning hole 1139. The fourth positioning protrusions 135 are detachably located in the fourth positioning holes 1139 to more securely position the rear tray 13 in the use position.

[0036] Please see Figure 3 and Figure 5 The front panel 115 of the server chassis 10 includes a first limiting portion 1151. The opposite sides of the first limiting portion 1151 are respectively connected to two side panels 113 and are parallel to the bottom plate 111. When the front tray 12 is in the use position, the first limiting portion 1151 can be used for the front tray 12 to abut against, thereby supporting the weight of the front tray 12, and serving as a limiting structure for the front tray 12 in the use position to prevent the front tray 12 from being excessively pressed down due to external forces or its own weight.

[0037] Please see Figure 4 and Figure 5 Each of the two side panels 113 of the server chassis 10 may include two third limiting parts 1136. When the rear tray 13 is in the use position, the two third limiting parts 1136 can be used for the rear tray 13 to abut against, thereby serving as a limiting structure for the rear tray 13 in the use position to prevent the rear tray 13 from being excessively pressed down due to external force or its own weight.

[0038] Please see Figure 5 The server chassis 10 may also include a plurality of fasteners 15. These fasteners 15 are engaged with screw holes on the first pivot 123 and the second pivot 133 to securely fasten the front tray 12 and the rear tray 13 to the two side plates 113 of the housing 11.

[0039] Please see Figure 3 and Figure 6 Each of the two side panels 113 of the server chassis 10 may include a second limiting part 1135. When the front tray 12 pivots from the use position to the flip position, the second limiting part 1135 is used for the front tray 12 to abut against, thereby serving as a limiting structure for the front tray 12 when it is in the flip position, preventing the front tray 12 from continuing to pivot towards the position of the rear tray 13 after reaching the flip position and interfering with the rear tray 13.

[0040] Please see Figure 4 and Figure 6Each of the two side panels 113 of the server chassis 10 may include a fourth limiting part 1137. When the rear tray 13 pivots from the use position to the flip position, the fourth limiting part 1137 is used for the rear tray 13 to abut against, thereby serving as a limiting structure for the rear tray 13 in the flip position, preventing the rear tray 13 from continuing to pivot to the position of the front tray 12 after reaching the flip position and interfering with the front tray 12.

[0041] It must be noted that the following embodiments use the component reference numerals and some content from the foregoing embodiments, employing the same or similar reference numerals to represent the same or similar components, and omitting descriptions of identical technical content. For explanations of the omitted parts, please refer to the foregoing embodiments; these will not be repeated in the following embodiments.

[0042] Please see Figures 7 to 8 . Figures 7 to 8 A schematic diagram of the operation of a server device according to another embodiment of the present invention is shown. In this embodiment, the server device 1 includes a server chassis 10, a motherboard 20, a graphics processor 30, a hard disk module 40, a power distribution module 50, a power supply module 60, and a memory module 70.

[0043] The server chassis 10 includes a housing 11, a front tray 12, and a rear tray 13. The housing 11 includes a bottom plate 111, two side plates 113, a front plate 115, and a back plate 117. The bottom plate 111, the two side plates 113, the front plate 115, and the back plate 117 together surround an accommodating space 119. The accommodating space 119 has an upper space 1191 and a lower space 1192.

[0044] The front tray 12 is pivotally located in the upper space 1191 via two first pivots 123. The rear tray 13 is pivotally located in the upper space 1191 via two second pivots 133 and is located between the back panel 117 and the front tray 12.

[0045] The motherboard 20 is mounted on the base plate 111 and located in the lower space 1192.

[0046] The graphics processor 30 is located in the lower space 1192. The graphics processor 30 is further away from the back panel 117 than the motherboard 20. When the server unit 1 is assembled, the graphics processor 30 is partially located below the front tray 12.

[0047] The hard drive module 40 is detachably mounted on the front tray 12. The hard drive module 40 and the front tray 12 are pivotable relative to the housing 11. The hard drive module 40 is electrically connected to the motherboard 20 via a wire-to-wire connection cable 41.

[0048] The power distribution module 50 is detachably mounted on the rear tray 13. The power distribution module 50 and the rear tray 13 are pivotable relative to the housing 11. The power distribution module 50 is electrically connected to the motherboard 20 via a wire-to-wire connection cable 51.

[0049] The power supply module 60 is electrically connected to the board-to-board ground of the power distribution module 50 on the side near the backplane 117.

[0050] The memory module 70 is located above the motherboard 20 and in the lower space 1192. The memory module 70 may be, but is not limited to, a dual in-line memory module (DIMM).

[0051] like Figure 7 As shown, in the server device 1, the front tray 12, which houses the hard drive module 40, and the rear tray 13, which houses the power distribution module 50, are both laid flat in the use position. The operator positions the front tray 12 in the use position by using the first positioning protrusion 124 and the first use positioning hole 1131, and positions the rear tray 13 in the use position by using the second positioning protrusion 134 and the second use positioning hole 1133. The operator can also use multiple fasteners (not shown) to more securely lock the front tray 12 and the rear tray 13 to the two side plates 113. Next, the operator can insert the power supply module 60 into the power distribution module 50 from the side where the back plate 117 is located, along an insertion direction A parallel to the base plate 111.

[0052] like Figure 8 As shown, when the operator fully inserts the power supply module 60 into the server chassis 10, its electrical connector mates with and connects to the corresponding electrical connector of the power distribution module 50, thereby supplying power to the entire server device 1 and enabling the server device 1 to operate. When the server device 1 is operating, both the front tray 12 and the rear tray 13 are in the usage position.

[0053] Please see Figures 9 to 10 . Figures 9 to 10 A schematic diagram of the operation of a server device according to another embodiment of the present invention is shown.

[0054] like Figure 9 As shown, when the operator needs to maintain the server device 1 (e.g., repair or replace the motherboard 20 or graphics processor 30 located in the lower space 1192), the power supply module 60 must first be pulled out of the server chassis 10 in the pull-out direction B, so as to separate it from the power distribution module 50 and stop the power supply to the server device 1.

[0055] Next, as Figure 10As shown, the operator can loosen the fasteners (not shown) that secure the front tray 12 and rear tray 13 to the two side plates 113. Next, the operator can pull the first positioning protrusion 124 and the second positioning protrusion 134 upwards towards the upper space 1191, separating them from the first positioning hole 1131 and the second positioning hole 1133, respectively. Then, the operator can pull the third positioning protrusion 125 and the fourth positioning protrusion 135 upwards towards the upper space 1191, separating them from the third positioning hole 1138 and the fourth positioning hole 1139, respectively.

[0056] Next, with the multiple positioning protrusions and multiple positioning holes separated, the operator can move the front tray 12 and the rear tray 13, and the first pivot 123 and the second pivot 133 will rotate together with the first rotating bracket 122 and the second rotating bracket 132 from the use position to the flip position, so as to drive the front tray 12 and the rear tray 13 to pivot to the flip position.

[0057] When the front tray 12 is pivoted 90° from the use position and located in the flip position, the front tray 12 first abuts against the second limiting part 1135, and then is positioned by the first positioning protrusion 124 and the first flip positioning hole 1132, thus maintaining it in the flip position. Similarly, when the rear tray 13 is pivoted 90° from the use position and located in the flip position, the rear tray 13 first abuts against the fourth limiting part 1137, and then is positioned by the second positioning protrusion 134 and the second flip positioning hole 1134, thus maintaining it in the flip position.

[0058] At this time, the front tray 12 with the hard disk module 40 and the rear tray 13 with the power distribution module 50 are flipped out of the server chassis 10, thereby completely freeing up the storage space 119 of the server chassis 10 and fully exposing the motherboard 20 and various functional modules inside the server chassis 10, so as to provide operators with a spacious and unobstructed working area.

[0059] Furthermore, when the front tray 12 and rear tray 13 are in the flipped position, since the hard drive module 40 and the power distribution module 50 are still fixed to the front tray 12 and rear tray 13 respectively, it is not necessary to disconnect the cables 41 and 51 connecting the hard drive module 40 and the power distribution module 50 to the motherboard 20. This not only effectively reduces the risk of cable or connector damage caused by repeated plugging and unplugging, but also significantly simplifies the operation steps for operators to repair or replace internal components of the server device, greatly improving the convenience of disassembling and maintaining internal components of the server device.

[0060] According to the server chassis and server device of the above embodiments, by means of the configuration in which the front tray and the rear tray can pivot independently of each other, and in conjunction with the guide groove, the positioning protrusion, the positioning hole and the limiting structure of the use position and the flip position, the tray carrying the hard disk module and the power distribution module can be stably and smoothly flipped from the use position to the flip position without disassembling the module and without unplugging the cable.

[0061] Furthermore, when operators perform maintenance or assembly work on the server unit, they do not need to disassemble the server chassis trays or boards. They only need to flip the front and rear trays to fully expose the motherboard and various functional modules located within the storage space. This provides operators with an unobstructed working area, which is beneficial for operations such as cable routing, module inspection, and parts replacement. In this way, the risk of cable damage caused by frequent plugging and unplugging can be effectively reduced, the time required for maintenance and assembly can be significantly shortened, overall work efficiency can be improved, and the flexibility of the internal space configuration of the server can be increased.

[0062] Furthermore, this design, through its dual-pallet flipping structure and corresponding guide, positioning, and limiting configurations, achieves both structural stability of the server unit and ease of operation for the user without adding complex pull-out mechanisms or additional slide rails. This significantly improves the convenience of maintaining, disassembling, and managing cables for the server unit, while also ensuring its reliability during long-term operation.

[0063] Although the present invention has been disclosed above with reference to the foregoing embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of patent protection of the present invention shall be determined by the claims defined in the appended specification.
