As shown in FIG. 1, the graphics processor box includes a casing 100, a high-speed connector, a PCIE switch module 300 and a GPU module 200. The PCIE switch module 300, the high-speed connector and the GPU module 200 are arranged in the housing 100. The PCIE switch module 300 communicates with the GPU module 200 through the high-speed connector.

The casing 100 is used to install the high-speed connector, the PCIE switch module 300 and the GPU module 200. The cabinet 100 includes, for example, a cabinet main body 110 and a tray 120. The casing main body 110 is, for example, a rectangular parallelepiped casing with an open end. The casing body 110 has a bearing surface 110a. The bearing surface 110a is, for example, an end surface with the largest area of the rectangular parallelepiped shell. The bearing surface 110a is adjacent to the opening. The high-speed connector and the GPU module 200 are fixed on the bearing surface 110a.

FIG. 2 is a schematic diagram of a three-dimensional structure of a tray and a PCIE switch module of this embodiment. As shown in FIG. 2, the tray 120 is used to install the PCIE switch module 300, and is detachably and pullably located at the opening to close the main body 110 of the casing. The tray 120 is, for example, substantially L-shaped, and includes a first end surface 120a and a second end surface 120b perpendicular to each other, and a third end surface 120c connecting and fixing the first end surface 120a and the second end surface 120b. When the tray 120 is fixed on the casing main body 110, the first end surface 120a is used to close the opening of the casing main body 110, and its shape is the same as the shape of the opening, and the area is smaller than the area of the opening, and the second end surface 120b For installing the PCIE switch module 300, the second end surface 120b is stacked on the carrying surface 110a, covering part of the carrying surface 110a, and exposing the modules installed in the chassis body 110, such as the GPU module 200. The third end surface 120c is, for example, a hollow triangle. One or two first handles 121 are provided on the second end surface 120b of the tray 120 on the side facing away from the opening of the casing body 110. The first handle 121 is used to push and pull the tray 120 to move in the horizontal direction. When there is one first handle 121, the first handle 121 is located at the center of the second end surface 120b; when there are two first handles 121, the first handle 121 is symmetrically arranged on the second end surface 120b.

Optionally, a pair of guide rails (not shown in the figure) are provided on two opposite end surfaces of the bearing surface 110a of the casing body 110. The guide rail is perpendicular to the direction of the opening in the main body 110 of the casing. The third end surface 120c of the tray 120 has a pulley matching the guide rail, so that the pulley can move back and forth on the guide rail in a direction perpendicular to the opening, so that the tray 120 can be drawn along the guide rail. It is connected to the main body 110 of the casing.

On the outer wall of the main body 110 of the casing, specifically, two opposite end surfaces on both sides of the bearing surface 110a are provided with limit posts (not shown in the figure). The limiting column is, for example, arranged on the outside of the main body 110 of the casing.

The third end surface 120c of the tray 120 also has a rotatable stop block 122. The stop block 122 has a slot for clamping the limit post. When the tray 120 enters the main body 110 of the casing along its drawing direction and reaches a preset position, the stop block 122 may be clamped on the limit post, so that the tray 120 is fixed on the main casing 110. When the tray 120 leaves the main body 110 of the casing, the stop block 122 is rotated (for example, counterclockwise), so that the limit post leaves the slot, and the tray 120 is detached from the main casing 110. Here, the stop block 122 and the card slot limit the tray 120 to prevent the tray 120 from moving back and forth in the direction in which it enters the main body 110 of the casing.

The tray 120 also has a drawing auxiliary structure. The drawing auxiliary structure includes a second handle 1231 and a locking structure 1232. The locking structure 1232 is disposed on the third end surface 120c of the tray 120 and faces the two sides of the opening of the main body 110 of the casing. The second handle 1231 is provided at a position where the third end surface 120c is close to the second end surface 120b. The locking structure 1232 is connected to the second handle 1231. Specifically, the locking structure 1232 and the second handle 1231 are connected through a spring, for example. The second handle 1231 and the main body 110 are arranged at an acute angle, for example, at 60°. When the tray 120 enters the preset position in the main body 110 of the casing, the second handle 1231 is rotated clockwise, the pulling auxiliary structure pushes the tray 120 forward, and the second handle 1231 is clamped on the limit post To prevent the second handle 1231 from rotating counterclockwise; when the tray 120 leaves the main body 110 of the casing, press the limit post, so that the second handle 1231 bounces counterclockwise, for example, bounces 10°, and then counterclockwise By rotating the second handle 1231, the auxiliary tray 120 is separated from the main body 110 of the casing. It can be seen that the tray 120 can be easily disassembled and installed through the pulling auxiliary structure without tools, which is beneficial to the mechanical cooperation when the PCIE switch module 300 is compatible, and is also beneficial to transportation and maintenance.

Optionally, the casing main body 110 and the second handle 1231 are provided with an auxiliary positioning structure, for example, an auxiliary limiting post located on the casing main body 110 and an auxiliary card slot located on the second handle 1231 to prevent PCIE exchange The subsequent shaking of the connector module 300 and the high-speed connector causes damage to the high-density interface. A conductive material, such as conductive foam, is also provided on the side of the tray 120 facing the bearing surface 110a of the main body 110 of the casing to avoid the electrical influence caused by static electricity, and to avoid the first end surface 120a of the tray 120 and the main body of the casing at the same time. Damage caused by direct contact between 110, such as contact, abrasion, iron filings, static electricity, etc.

Optionally, both the first end surface 120a of the tray 120 facing the bearing surface 110a and the third end surface 120c have auxiliary positioning posts to further restrict the displacement of the tray 120 along the direction in which the tray 120 enters the casing main body 110.

The GPU module 200 is placed on the bearing surface 110a of the casing main body 110, and the GPU module 200 is disposed on a side of the casing main body 110 away from the opening. The GPU module 200 is, for example, screwed to the main body 110 of the casing. The GPU module 200 includes, for example, a GPU motherboard and at least two interconnected GPU cards inserted on the GPU motherboard. The at least two GPU cards are, for example, intel GPU cards or AMD GPU cards, and a gap space is provided between adjacent GPU cards.

The PCIE switch module 300 is, for example, a PCIE switch motherboard. The PCIE switch module 300 uses, for example, a PLX9797 chip, which is conducive to exerting the extreme performance of the GPU module 200. The PCIE switch module 300 can be compatible with an intel GPU card or an AMD GPU card, which maximizes the use of the PCIE switch module 300, achieves the function of expanding PCIE, and reduces the cost.
