In order to make the aforementioned objects, features and advantages of the embodiments of the present application more comprehensible, embodiments of the present application are described in detail below with reference to the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the present application and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.

Example one

Referring to fig. 1 to 8, an expansion module for being installed in a chassis 300 having a drawing opening 310 is provided in an embodiment of the present disclosure. The expansion module may be a PCIE expansion module, but is not limited thereto.

The expansion module comprises an expansion component 100 and a switching component 200. The adapter module 200 is fixedly connected in the chassis 300, and is used for implementing voltage or signal transmission between an expansion card (not shown in the figure) in the expansion module 100 and a motherboard located in the chassis.

Expansion assembly 100 includes a mount 120 and at least two expansion members 110. The mount 120 is disposed within the chassis 300, for example, the mount 120 is fixedly attached to the bottom plate of the chassis 300. The mounting member 120 is used to provide support to the expansion member 110 to facilitate mounting of the expansion member 110 within the chassis.

At least two expansion members 110 are slidably and spacedly disposed on the mounting member 120. At least two expansion members 110 are slidably provided on the mounting member 120 in a length direction of the mounting member 120, and at least two expansion members 110 are provided at intervals in a height direction of the mounting member 120. The length direction may be the Y direction in fig. 3, and the height direction may be the X direction in fig. 3. In this embodiment, the expansion element 110 is used for carrying an expansion card. The expansion card may include a network card, a display card, and a GPU card, but is not limited thereto.

At least two expansion members 110 move independently of each other relative to mounting member 120 to extend through the drawing port 310 (see fig. 1). When the expansion card on the expansion piece 110 needs to be replaced or repaired, the expansion piece 110 can be pulled out from the pull-out opening 310 of the chassis 300, and then the expansion card on the expansion piece 110 can be detached to replace or repair the expansion card. Compared with the prior art, the expansion module designed in the embodiment of the application can replace or repair the expansion card in the case 300 without detaching the top cover of the case 300, is simple to operate, greatly simplifies the disassembly and assembly of the expansion card, improves the disassembly and assembly efficiency of the expansion card, and further reduces the maintenance difficulty and cost of the server.

In the present embodiment, the at least two expansion pieces 110 are independently provided, that is, the expansion cards on the at least two expansion pieces 110 are also independently provided. When one of the expansion pieces 110 is damaged, the damaged expansion piece 110 can be pulled out from the drawing opening 310 of the chassis 300 separately, so that the disassembly of at least two expansion pieces 110 is not interfered with each other, and the disassembly and assembly efficiency of the expansion card is improved.

It should be noted that, in this embodiment, the top cover of the chassis 300 does not need to be removed for the detachment and installation of the expansion module, and when the expansion card supports hot plug, the expansion card can be replaced and maintained without shutdown of the server. By the arrangement, the server can be ensured to be always in a working state, and the working efficiency of the server is improved.

The adaptor assembly 200 is fixedly connected to the chassis 300 (see fig. 1) and disposed adjacent to the expansion assembly 100, so as to shorten the distance between the adaptor assembly 200 and the expansion assembly 100, thereby facilitating the docking between the adaptor assembly 200 and the expansion assembly 100.

In the present embodiment, at least two expansion members 110 are detachably connected to the adaptor assembly 200, respectively, so as to realize the movement of at least two expansion members 110. Illustratively, the patching assembly 200 includes at least two female connectors 210; at least two female connectors 210 are arranged at intervals, for example, at least two female connectors 210 are arranged at intervals along the height direction of the mounting member 120. Each extension member 110 includes a male connector 111 removably connected to one of the female connectors 210. That is, each extension 110 is provided with a male connector 111 detachably connected to its corresponding female connector 210, for example, the male connector 111 is plugged into the female connector 210.

When the expansion card on the expansion piece 110 needs to be replaced or maintained, the expansion piece 110 is controlled to move in the direction away from the adapter assembly 200, in the process, the male connector 111 of the expansion piece 110 and the female connector 210 of the adapter assembly 200 are separated, so that the power-off of the expansion piece 110 and the server is realized, and then the expansion piece 110 continues to move in the direction away from the adapter assembly 200 until the expansion piece moves out of the drawing opening, so that the replacement or maintenance of the expansion card on the expansion piece is facilitated.

When the replacement or repair of the expansion card on the expansion piece 110 is completed, the expansion piece 110 is controlled to move toward the patching assembly until the male connector 111 of the expansion piece 110 and the female connector 210 of the patching assembly 200 are connected to realize the electrical connection between the expansion piece 110 and the server.

In this embodiment, the expansion piece 110 and the adapting assembly 200 are mutually matched through the male connector 111 and the female connector 210, so that the expansion piece 110 and the adapting assembly 200 are connected, and the expansion piece and the adapting assembly have the advantages of simple connection structure and convenience in connection.

In one possible embodiment, mount 120 has a mounting cavity 121 and first and second openings in communication with mounting cavity 121, the first opening being disposed opposite the second opening.
