The server device 10 of this embodiment includes a housing 11, an adapter board 12, an expansion rack 13, and a plurality of expansion cards 136. The adapter board 12 is, for example, a circuit board and is disposed in the housing. The expansion rack 13 is replaceably installed in the housing and includes an expansion card bracket 131, an adapter card bracket 132, a plurality of first positioning structures 133, a plurality of second positioning structures 134, an adapter card 135, a plurality of expansion cards 136, and an adapter board connector 137.

The adapter card bracket 132 can be slidably disposed on the expansion card bracket 131 and is located at a loading and unloading position or a fixed position. In detail, the expansion card bracket 131 includes a bottom plate 1311 and a side plate 1312. The bottom plate 1311 is connected to the side plate 1312. These first positioning structures 133 are disposed on the bottom plate 1311. The adapter card bracket 132 includes a positioning plate 1321, an assembly plate 1322 and a top plate 1323. The positioning plate 1321 is connected to the assembly plate 1322. The top plate 1323 is connected to one side of the assembly plate 1322 away from the positioning plate 1321. These second positioning structures 134 are disposed on the positioning plate 1321. These first positioning structures 133 are, for example, positioning columns. The second positioning structures 134 are positioning grooves such as gourd holes, for example.

The second positioning structures 134 are slidably disposed on the first positioning structures 133, respectively, so that the adapter card bracket 132 is located at a loading and unloading position, so that the second positioning structures 134 are detachably disposed on the first positioning structures 133. When the adapter card bracket 132 is located at the loading and unloading position, the adapter card bracket 132 can be assembled or disassembled from the expansion card bracket 131. When the adapter card bracket 132 slides from the loading and unloading position to a fixed position, the first positioning structures 133 are respectively engaged with the second positioning structures 134, so that the adapter card bracket 132 is positioned on the expansion card bracket 131.

The adapter card 135 is, for example, a PCIe adapter card 135, and includes a board 1351 and a plurality of slots 1352. The board 1351 is fixed to the adapter bracket 132 and is located between the side plate 1312 and the assembly board 1322. The slots 1352 are disposed on the board 1351 and penetrate the assembly board 1322. The slots 1352 are used for plugging in expansion cards 136, such as PCIe expansion cards 136, so that the expansion cards 136 are electrically connected to the adapter board 12 through the slots 1352.

The adapter board connector 137 is used to allow the expansion cards 136 to be electrically connected to the adapter board 12, for example, board-to-board.

In this embodiment, since the adapter card bracket 132 is slidably disposed on the expansion card bracket 131 through the first positioning structure 133 and the second positioning structures 134, the adapter card bracket 132 can be simply fixed to the expansion card bracket 131 or removed from the expansion card bracket 131 by manual sliding, without the need to use other installation tools to disassemble and assemble in the housing 11. In this way, the convenience of disassembling and assembling the expansion bracket assembly 13 in the housing 11 can be improved.

In addition, since these expansion cards 136 are electrically connected to the adapter board 12 through the adapter board connector 137 disposed on the adapter card 135, the adapter card 135 does not need to be electrically connected to the adapter board 12 through gold fingers or cables, thereby simplifying the structure of the server device 10. In this way, the convenience of disassembling and assembling the expansion rack assembly 13 in the housing 11 can be further improved.

Figure 7 is a three-dimensional schematic diagram of the expansion rack assembly in the server device of Figure 1 being assembled in front of the housing. Figure 8 is a three-dimensional schematic diagram of the expansion rack assembly in the server device of Figure 1 being assembled to the housing.

When the user installs the expansion bracket assembly 13 with the expansion cards 136 on the housing 11, as shown in FIG4, first, the adapter card 135 is fixed to the adapter card bracket 132 through the first fasteners 16, and the slots 1352 are penetrated into the assembly plate 1322. Then, as shown in FIG5, the adapter card bracket 132 is fixed to the expansion card bracket 131 along the direction A through the second fasteners 17 and the third fasteners 18. At this time, the second positioning structures 134 are respectively arranged on the first positioning structures 133, so that the adapter card bracket 132 is located at the loading and unloading position. Then, the adapter card bracket 132 is slid along the direction B, so that the adapter card bracket 132 slides from the loading and unloading position to the fixed position. At this time, the first positioning structures 133 are respectively engaged with the second positioning structures 134 to position the adapter bracket 132 on the expansion card bracket 131. Then, as shown in FIG6 , the expansion cards 136 are respectively inserted into the slots 1352 along direction C. In this way, the expansion bracket set 13 and the expansion cards 136 are assembled.

Next, as shown in FIGS. 7 to 9 , the user can install the expansion frame 13 into the housing 11 along the direction D through the handle 15. Then, the expansion frame 13 is electrically connected to the adapter plate 12 through the adapter plate connector 137. Then, the user rotates the handle 15 along the direction E so that the second buckle portion 151 of the handle 15 is buckled into the first buckle portion 141 of the flexible stopper 14, so as to retract the handle 15 into the flexible stopper 14. In this way, the installation of the expansion frame 13 and the housing 11 can be completed.

On the contrary, when the user wants to remove the expansion rack 13 from the server device 10 for repair or replacement, first, the first buckle portion 141 of the flexible stopper 14 is released from the second buckle portion 151 of the handle 15, and the handle 15 is rotated in the opposite direction of direction E to move the first buckle portion 141 away from the second buckle portion 151. Then, the expansion rack 13 is disconnected from the electrical connection with the adapter plate 12 through the adapter plate connector 137, and the expansion rack 13 is moved out of the housing 11 in the opposite direction of direction D through the handle 15. In this way, the expansion rack 13 can be removed from the server device 10.

According to the expansion rack assembly and server device of the above embodiment, since the riser card bracket is slidably disposed on the expansion card bracket through the first positioning structure and the second positioning structures, the riser card bracket can be simply fixed to the expansion card bracket or removed from the expansion card bracket by manual sliding, without the need for additional installation tools to be disassembled in the case. In this way, the convenience of disassembling and assembling the expansion rack assembly in the case can be improved.

In addition, since these expansion cards are electrically connected to the adapter board through the adapter board connector provided on the adapter card, the adapter card does not need to be electrically connected to the adapter board through gold fingers or cables, thus simplifying the structure of the server device. In this way, the convenience of disassembling and assembling the expansion rack in the case can be further improved.
