[0033] like Figures 1 to 3 As shown, the present invention provides a board and card fixing device, which includes a tray 1 and a handle 2. The tray 1 has an installation space for accommodating the board and card. A fixing hole for the bolt to pass through is opened on the tray 1, and the fixing hole is arranged opposite to the bolt hole of the board and card. First elastic clips 13 are arranged on both sides of the tray 1, and the first elastic clips 13 are clamped in the main card interface of the inner wall of the mainboard slot; the two ends of the handle 2 are respectively connected to the first elastic clips 13 on both sides of the tray 1, and the two first elastic clips 13 can approach each other under the pulling force of the handle 2 to disengage from the main card interface. In this embodiment, since the tray 1 has an installation space, the installation space is used to accommodate the board, and since the tray 1 is also provided with a fixing hole, which is arranged opposite to the bolt hole of the board, the board can be fixedly installed in the installation space by bolts, thereby being connected to the tray 1 as a whole, and conveniently installed in the motherboard slot of the computer; since the first elastic buckles 13 are arranged on both sides of the tray 1, and the first elastic buckles 13 are arranged in the main card interface of the inner wall of the motherboard slot, the board can be fixed in the motherboard slot through the tray 1 to ensure the stability of the board during use; The tray 1 is also provided with a handle 2, and the two ends of the handle 2 are respectively connected to the first elastic buckles 13 on both sides. When the handle 2 is pulled, the two first elastic buckles 13 can be elastically close to each other and detached from the main card interface on the inner wall of the motherboard slot under the action of the pulling force, so that the tray 1 is detached from the card connection with the motherboard slot, and the tray 1 is pulled out from the motherboard slot under the drive of the handle 2; the board card fixing device has a simple structure, and the tray 1 can be detached from the card connection of the motherboard slot by pulling the handle 2 with one hand, and the tray 1 can be taken out from the motherboard slot at the same time, which simplifies the operation and greatly facilitates the user. Specifically, the tray 1 is a shovel-shaped structure with an installation space surrounded by three sides; the board card is inserted into the motherboard slot of the computer through the tray 1, and is connected to the computer motherboard through the connection port; the first elastic buckle 13 is convexly arranged on both sides of the tray 1, and when the tray 1 is inserted into the motherboard slot, the tray 1 is pushed into the motherboard slot, and the first elastic buckle 13 will be elastically deformed and clamped in the main card interface on the inner wall of the motherboard slot, thereby achieving the fixation of the tray 1 and the motherboard.

[0034] Furthermore, if Figure 2As shown, the tray 1 includes a tray body 11, and the tray body 11 includes a bottom plate 111 and two side wall plates 112 arranged on the bottom plate 111. An installation space is formed between the bottom plate 111 and the two side wall plates 112, and a fixing hole is opened in the bottom plate 111. In this embodiment, the tray body 11 is the main structure of the tray 1, the bottom plate 111 is used to fix the board, and the two side wall plates 112 are arranged on the bottom plate 111 oppositely and parallel to each other, and the side wall plates 112 are used to abut against both sides of the board.

[0035] Specifically, Figure 2 and Figure 3 As shown, the tray 1 also includes an assembly frame 12, which includes two winglets 121, which are respectively connected to the two side wall plates 112, and each winglet 121 is provided with a first elastic buckle 13. In this embodiment, the two winglets 121 of the assembly frame 12 are respectively connected to the two side wall plates 112, and the first elastic buckle 13 is provided on the winglets 121; specifically, the winglets 121 are detachably connected to the side wall plates 112 by screws, and when the first elastic buckle 13 is damaged, the winglets 121 can be removed to replace the first elastic buckle 13, without the need to repair or replace the entire tray 1, thereby improving the practicality of the board fixing device.

[0036] Specifically, Figure 1 and Figure 2 As shown, the assembly frame 12 also includes a connecting piece 122, and the two ends of the connecting piece 122 are respectively connected to the two wing pieces 121. In this embodiment, the two wing pieces 121 are connected into an integral structure through the connecting piece 122, thereby improving the integrity of the assembly frame 12 and facilitating assembly; specifically, the two ends of the handle 2 are connected to the first elastic buckles 13 on the two side wing pieces 121, and the connecting piece 122 is directly connected to the two side wing pieces 121. The connecting piece 122 is closer to the tray body 1 relative to the handle 2. Therefore, when the tray 1 is pulled out from the motherboard slot, the user can avoid the interference of the connecting piece 122 and directly pull the handle 2, thereby preventing the connecting piece 122 from being damaged due to pulling.

[0037] Specifically, Figure 1 and Figure 2 As shown, the width of the connecting piece 122 is smaller than the width of the handle 2. In this embodiment, the connecting piece 122 is closer to the disk body 1 relative to the handle 2, that is, when the board fixing device is inserted into the motherboard slot, the handle 2 is located outside the connecting piece 122, so that it is easy to pull by hand; specifically, because the width of the connecting piece 122 is smaller than the width of the handle 2, the fingers can easily pull the handle 2 outward from both sides of the handle 2, avoiding the interference of the connecting piece 122 on the fingers when pulling the handle 2, and further reducing the difficulty of operation.

[0038] Specifically, Figure 1As shown, the edge of the connecting piece 122 along the width direction is rolled inward to form an anti-scratch edge 1221. In this embodiment, the edge of the connecting piece 122 is folded inward and hammered to form a curved and smooth anti-scratch edge 1221 to prevent the fingers from being scratched and injured by touching the edge of the connecting piece 122 when pulling the handle 2. Specifically, the connecting piece 122 is made of stainless steel and has a certain strength and hardness, and the handle 2 is a plastic part made of PA66 resin and has good elasticity and flexibility.

[0039] Specifically, Figure 2 and Figure 3 As shown, the first elastic buckle 13 includes a first spring piece 131 and a clamping portion 132 disposed on the first spring piece 131. The first spring piece 131 is convexly disposed on the wing 121. The first spring piece 131 is connected to the handle 2. The clamping portion 132 can abut against the side wall plate 112 of the main card interface. When the handle 2 pulls the first spring piece 131, the first spring piece 131 can be elastically deformed to approach the wing 121. In this embodiment, the first spring piece 131 is disposed at the end of the wing 121. The clamping portion 132 is disposed on the first spring piece 131. When the board and card fixing device is inserted and installed, the first spring piece 131 is elastically deformed and approaches the wing 121. Then the clamping portion 132 is clamped in the main card interface on the inner wall of the motherboard slot.

[0040] Specifically, Figure 3 As shown, the wing 121 is also provided with a second elastic buckle 14, which is clamped in the secondary card interface of the inner wall of the mainboard slot. In this embodiment, the second elastic buckle 14 is arranged on the wing 121 at intervals from the first elastic buckle 13, and the inner wall of the mainboard slot is provided with a secondary card interface matching the second elastic buckle 14. When the first elastic buckle 13 is clamped in the primary card interface, the second elastic buckle 14 is clamped in the secondary card interface; the second elastic buckle 14 cooperates with the first elastic buckle 13 to jointly realize the plug-in fixation of the tray 1 and the mainboard, thereby improving the connection stability and reliability.

[0041] Furthermore, if Figure 1 As shown, the board fixing device further includes a flexible pad 3, which is arranged in the installation space. In this embodiment, the flexible pad 3 is made of rubber or sponge, and the flexible pad 3 is fixed on the bottom plate 111, which can buffer the impact between the board and the disk body 11, thereby protecting the board from damage.

[0042] This embodiment also provides an AI board unit, which includes a board and the above-mentioned board fixing device, and the board is fixed in the installation space. In this embodiment, the board is fixed on the board fixing device and installed on the computer motherboard through the board fixing device. The connection is stable and reliable. When disassembling, the AI ​​board unit can be taken out from the motherboard slot by one hand through the handle, which reduces the difficulty of disassembly and greatly facilitates the user.
