[0043] For details, please refer to Figure 1 to Figure 2, an embodiment of the present application provides a modular installation structure for a graphics card and an acquisition card, comprising a base plate 1 and a base 2, wherein the base 2 is detachably fixedly installed on the base plate 1; the base 2 comprises a vertical plate 21 and a partition plate 22, wherein the partition plate 22 is fixedly connected to the vertical plate 21, the vertical plate 21 is detachably fixedly installed on the base plate 1, and the partition plate 22 is mounted on the upper part of the base plate 1 through the vertical plate 21; the base 2 is divided into a first installation space 11 and a second installation space 12 by the partition plate 22 along a direction from approaching to away from the base plate 1, the first installation space 11 is used to accommodate the acquisition card 6 and provide for the horizontal installation of the acquisition card 6, the second installation space 12 is used to accommodate the graphics card 3 and provide for the horizontal installation of the graphics card 3, and the graphics card 3 and the acquisition card 6 are horizontally stacked and fixed to the upper part of the base plate 1 through the partition plate 22.

[0044] The modular installation structure of the graphics card and the acquisition card provided in the embodiment of the present application can realize the integration of the graphics card 3 and the acquisition card 6 through the modular installation structure, simplify the installation procedure, realize modular and convenient assembly and maintenance, and can effectively avoid the graphics card 3 and the acquisition card 6 being damaged during transportation or having poor contact in the slots due to being placed vertically. In addition, the base 2 is detachably fixed on the base plate 1, and is relatively easy to disassemble when installation and fixation are not required or when the graphics card and the acquisition card need to be inspected and cleaned. The installation structure is simple and the fixing reliability is high. The graphics card 3 and the acquisition card 6 are fixed in a horizontal stacking manner through the partition plate 22, which saves height space, makes the product thinner and more beautiful in appearance.

[0045] In some embodiments, the bottom plate 1 can be the bottom plate of the installation box, and the bottom plate 1 as a whole is a rectangular plate structure. Since the base 2 and the graphics card 3 and the acquisition card 6 are all fixedly installed on the upper part of the bottom plate 1, the horizontal cross-sectional dimension of the bottom plate 1 is larger than the horizontal cross-sectional dimension of the base 2, so that the bottom plate 1 can provide sufficient bearing surface to support the graphics card 3 and the acquisition card 6.

[0046] In some embodiments, a plurality of circular holes are provided on the partition plate 22, and the plurality of circular holes can be circular holes that fit the shape of the bottom of the graphics card, so as to facilitate the embedding and fixing of the graphics card 3 on the base 2. In addition, by providing the circular holes, the weight of the base 2 itself is reduced, which facilitates heat dissipation and line connection when the graphics card 3 is in use.

[0047] To facilitate fixing the base 2 on the bottom plate 1, in some embodiments, a plurality of vertical plates 21 are provided, and the plurality of vertical plates 21 are fixedly connected to the partition plate 22, and each of the vertical plates 21 includes a horizontal section 211 and a vertical section 212; one end of the vertical section 212 is fixedly connected to the bottom surface of the partition plate 22 close to the bottom plate 1, and the other end of the vertical section 212 is fixedly connected to the horizontal section 211 and the connection between the two is bent at an angle; the horizontal section is fixedly installed on the bottom plate 1 by a fastener 5, and the horizontal section 211 is in contact with the surface of the bottom plate 1.

[0048] Among them, multiple vertical plates 21 can be symmetrically arranged along two opposite sides of the base 2, and the number of vertical plates 21 should be sufficient to support the partition plate 22 and the graphics card 3 fixed thereon. For example, the number of vertical plates 21 is set to four, and among the four vertical plates 21, two vertical plates 21 are arranged at the bottom of one long side of the partition plate 22, and the other two vertical plates 21 are arranged at the bottom of the other opposite long side of the partition plate 22, so that the four vertical plates 21 can form four legs to support the partition plate 22.

[0049] In addition, in order to improve the stability of the vertical plate 21 when it is installed on the base plate 1, the angle formed by the bending at the connection between the vertical section 212 and the horizontal section 211 when the two are connected can be 90°, and the fastener 5 can be a screw; correspondingly, a screw hole threadedly connected to the screw is opened on the base plate 1 or a threaded seat threadedly connected to the screw is fixedly set, and then the threaded section of the screw is passed through the horizontal section 211 and threadedly connected to the screw hole / threaded seat, so that the vertical plate 21 can be fixed to the base plate 1.

[0050] Of course, in some scenarios where the base 2 does not need to be disassembled, the fastener 5 may also be a connector that can be interference-fitted with the base plate 1, such as a pin.

[0058] In some embodiments, the connecting component 7 includes a block 71 and a slot 72, the block 71 is connected to the side of the wing plate 42, and the slot 72 is correspondingly opened on the retaining edge 221; the block 71 is elastic, and when the wing plate 42 is covered to a position corresponding to the slot 72, the block 71 can be embedded in the slot 72 and be snap-fitted with the slot 72.

[0059] In some embodiments, the card blocks 71 and the card slots 72 are respectively arranged in correspondence with each other, and the multiple card blocks 71 are arranged on the sides of the two wing plates 42 that are close to each other, and the multiple card blocks 71 are arranged at intervals along the length direction of the wing plates 42, and the multiple card slots 72 correspond to the card blocks 71 and are opened at intervals along the length direction of the retaining edge 221.
