[0031] Embodiment 1

[0032] Reference Figure 1 -Attached Figure 4 , Embodiment 1 of the present invention proposes a fixing structure, which is used to fix a part to be fixed on a fixing frame 1, and includes: a bracket 2, which is installed in the accommodating cavity 13 of the fixing frame 1 and is located on one side of the fixing frame 1 along the first direction A, and is used to cooperate with the fixing frame 1 to limit the position of the part to be fixed in the first direction A; and a baffle 3, which is movably connected to one side of the bracket 2 in the second direction B, and can be switched between a first position and a second position relative to the bracket 2; wherein, when the baffle 3 is in the first position, the baffle 3 is used to cooperate with the fixing frame 1 to limit the position of the part to be fixed in the second direction B, and when the baffle 3 is in the second position, the baffle 3 is separated from the part to be fixed; the second direction B is perpendicular to the first direction A.

[0033] Specifically, the fixing frame 1 is used to carry the part to be fixed. The shape and size of the fixing frame 1 are not specifically limited here. In this embodiment, the fixing frame 1 is an L-shaped bracket 2 with a receiving cavity 13, whose long side extends along the first direction A and the short side extends along the second direction B. The bracket 2 is installed in the receiving cavity 13 of the fixing frame 1. The bracket 2 can be a plate-like structure of any shape, such as a rectangular plate, a square plate or a polygonal plate. The bracket 2 can be connected to the fixing frame 1 by bolt connection, snap connection or mortise and tenon connection. The bracket 2 is installed on one side of the fixing frame 1 along the first direction A and cooperates with the short side of the fixing frame 1 to clamp the two ends of the part to be fixed to limit the position of the part to be fixed in the first direction A. The baffle 3 is movably connected to the side of the bracket 2 in the second direction B and the baffle 3 is arranged opposite to the long side of the fixing frame 1. The movable connection here can be a rotation or sliding connection. When the baffle 3 is movably connected to the bracket 2, the baffle 3 may be provided with a slide groove extending along the first direction A, and the bracket 2 may be provided with a slider matched with the slide groove, so that the baffle 3 may slide to the first position and the second position relative to the bracket 2 along the first direction A. The baffle 3 and the bracket 2 may be rotatably connected via a rotating shaft, and the baffle 3 may be rotated to the first position and the second position around an axis extending along the second direction B. The specific size of the baffle 3 may be set according to actual needs, and the shape of the baffle 3 may be any shape, such as: a circular plate, a square plate, or a polygonal plate.

[0034] The present application provides a fixing structure, a riser bracket 2 and a chassis, the fixing structure comprising a bracket 2 and a baffle 3, the baffle 3 being movably connected to the bracket 2 and switchable between a first position and a second position relative to the bracket 2, when the baffle 3 is in the first position, the baffle 3 cooperates with the fixing frame 1 and is clamped at both ends of the part to be fixed along the second direction B to limit the position of the part to be fixed in the second direction B, the bracket 2 cooperates with the fixing frame 1 and is clamped at both ends of the part to be fixed along the first direction A to limit the position of the part to be fixed in the first direction A, thereby locking the part to be fixed to the fixing frame 1. When the baffle 3 is in the second position, the baffle 3 releases the clamping of the part to be fixed, at which time the part to be fixed can be pulled out of the fixing frame 1 along the second direction B. When fixing the part to be fixed, the fixing structure only needs to push the part to be fixed into the fixing frame 1 along the second direction B, and then the baffle 3 cooperates with the fixing frame 1 to clamp both ends of the part to be fixed along the second direction B, the operation is simple and convenient, and the operation space is not limited. In addition, a handle can be provided on the baffle for convenient operation, and the shape of the handle can be set according to actual needs, and the shape and position of the handle are not specifically limited here. For example, in this embodiment, the handle is a bent portion that is bent away from the accommodating cavity 13.

[0035] In some embodiments, the bracket 2 is perpendicular to the mounting surface 11 of the fixing frame 1; the baffle 3 is rotatably connected to the side of the bracket 2 opposite to the mounting surface 11 of the fixing frame 1 through a rotating shaft, and the baffle 3 can rotate around an axis perpendicular to the mounting surface 11 to switch the baffle 3 between the first position and the second position.

[0036] Specifically, as shown in the figure, the bracket 2 is perpendicular to the mounting surface 11 and the bracket 2 cooperates with the short side of the fixing frame 1 to limit the movement of the part to be fixed along the first direction A. The baffle 3 is rotatably connected to the side of the bracket 2 opposite to the mounting surface 11 through a rotating shaft. The baffle 3 can rotate around the rotating shaft perpendicular to the mounting surface 11, and the rotation angle can be any angle, such as 90°, 180° or 360°, which is not specifically limited here. For example, in this embodiment, the baffle 3 can be rotated 90° counterclockwise or clockwise to achieve the purpose of unlocking or fixing the part to be fixed. By rotatably connecting the baffle 3 to one side of the bracket 2, when the operator needs to fix or unlock the part to be fixed, he only needs to rotate the baffle 3 clockwise or counterclockwise, which is convenient to operate.

[0037] In some embodiments, the baffle 3 also includes an arc groove 31, which extends with the rotating shaft as the center; a boss 21 is arranged at one end of the bracket 2 close to the baffle 3, the boss 21 corresponds to and adapts to the arc groove 31, the boss 21 is inserted into the arc groove 31 and slides in the arc groove 31 as the baffle 3 rotates; wherein, when the baffle 3 is in the first position, the boss 21 is stuck in the end of the arc groove 31 away from the accommodating cavity 13; when the baffle 3 is in the second position, the boss 21 is stuck in the end of the arc groove 31 close to the accommodating cavity 13.

[0038] Specifically, Figure 1 and Figure 4 As shown, the arc groove 31 is arranged around the rotation axis, and the length of the arc groove 31 can be set according to the rotation angle of the baffle 3. The larger the rotation angle of the baffle 3 is, the longer the extension length of the arc groove 31 is. The size of the protrusion 21 and the arc groove 31 are adapted and corresponding, and the protrusion 21 extends to the arc groove 31 along the second direction B, which guides the rotation of the baffle 3 and makes it rotate more smoothly. In this embodiment, when the baffle 3 is in the first position, as shown in FIG. Figure 1 As shown, the baffle 3 is opposite to the mounting surface 11 of the fixing frame 1 and cooperates to limit the movement of the fixed member along the second direction B. The protrusion 21 is stuck in the end of the arc groove 31 away from the accommodating cavity 13, limiting the baffle 3 from rotating clockwise. When the baffle 3 is in the second position, as shown in FIG. Figure 4 As shown, the baffle 3 rotates 90° counterclockwise, and the baffle 3 is located on the side of the bracket 2 away from the accommodating cavity 13 to release the cooperation with the mounting surface 11, and the protrusion 21 is stuck in the end of the arc groove 31 close to the accommodating cavity 13, limiting the baffle 3 from continuing to rotate counterclockwise.

[0039] In some embodiments, the fixing structure also includes: a snap portion 32, which is provided on the baffle 3 and close to the two ends of the arc groove 31, and the snap portion 32 is a protrusion protruding toward the bracket 2; and a snap hole 22, which is provided at one end of the bracket 2 close to the baffle 3, and the snap hole 22 is adapted to the snap portion 32; when the baffle 3 rotates from the first position to the second position, the two snap portions 32 at the two ends of the arc groove 31 can be movably snapped into the snap hole 22 in turn to limit the rotation of the baffle 3.

[0040] Specifically, Figure 1 As shown, buckle parts 32 are respectively provided at both ends of the arc groove 31. In this embodiment, the buckle part 32 is a protrusion protruding toward the bracket 2. A clamping hole 22 is provided on the side of the bracket 2 that contacts the baffle 3. The clamping hole 22 is adapted to the protrusion. When the baffle 3 is in the first position, the clamping hole 22 corresponds to and clamps with one of the protrusions, so that the baffle 3 is fixed to the bracket 2 to keep it in the first position; when the baffle 3 is in the second position, the clamping hole 22 corresponds to and clamps with the other protrusion, so that the baffle 3 is fixed to the bracket 2 to keep it in the second position. This structure can easily fix the baffle 3 to keep it in the first position and the second position through mechanical interlocking without additional tools.

[0041] In some embodiments, the bracket 2 is installed on the fixing surface 12 of the fixing frame 1, the fixing surface 12 is perpendicular to the mounting surface 11 and the fixing surface 12 and the mounting surface 11 are surrounded by a accommodating cavity 13; the fixing structure also includes: a locking portion 33, which is arranged at the edge of the baffle 3 close to the fixing surface 12 and the locking portion 33 protrudes toward the fixing surface 12; and a fixing groove 121, which is arranged on the fixing surface 12 and corresponds to and adapts to the locking portion 33; when the baffle 3 is in the first position, the locking portion 33 is inserted into the fixing groove 121 to lock the baffle 3 to the fixing surface 12; when the baffle 3 is in the second position, the locking portion 33 is away from the fixing groove 121 to unlock the baffle 3 from the fixing surface 12.

[0042] Specifically, Figure 1-Figure 3As shown, in this embodiment, the fixing surface 12 is perpendicular to and adjacent to the mounting surface 11. In order to make the bracket 2 and the fixing frame 1 more firmly connected, one side of the bracket 2 is installed on the fixing surface 12. The edge of the baffle 3 close to the fixing surface 12 is provided with a locking portion 33 protruding from its edge, and the position corresponding to the fixing surface 12 and the locking portion 33 is provided with a fixing groove 121 adapted to the locking portion 33. When the baffle 3 rotates to the first position, the extension direction of the locking portion 33 is perpendicular to the fixing surface 12 and inserted into the fixing groove 121 to lock the baffle 3 to the fixing surface 12; when the baffle 3 rotates to the second position, the extension direction of the locking portion 33 is parallel to the fixing surface 12 and the locking portion 33 is away from the fixing groove 121. By providing the locking portion 33 and the fixing groove 121, the force in the second direction B received by the baffle 3 when it is in the first position to fix the to-be-fixed member can be evenly distributed to the entire baffle 3, so as to prevent the baffle 3 from being deformed and damaged due to local stress concentration, and also have the function of reinforcing the fixing of the baffle 3.

[0043] In some embodiments, the bracket 2 is detachably connected to the fixing surface 12 .

[0044] Specifically, Figure 1 As shown, in order to make the fixing structure adaptable to the fixed parts of different sizes, the bracket 2 can be detachably connected to the fixing surface 12 by bolt connection or mortise and tenon connection. For example, in this embodiment, multiple groups of mounting holes can be arranged at intervals on the fixing surface 12 along the first direction A, and each group of mounting holes has at least two screw holes. The side of the bracket 2 close to the fixing surface 12 is provided with corresponding screw holes, and the bracket 2 is fixed to the fixing surface 12 by bolts. The operator can install the bracket 2 on a group of mounting holes corresponding to the fixing surface 12 according to the length of the GPU card to be fixed along the first direction A.

[0045] In some embodiments, at least one slot 23 extending along the second direction B is provided on one side of the bracket 2 close to the accommodating cavity 13 for engaging with the part to be fixed.

[0046] Specifically, Figure 3 As shown, in order to make the part to be fixed on the fixing frame 1 more stable, a slot 23 extending along the second direction B is provided on one side of the bracket 2 close to the accommodating cavity 13, and the extension length of the slot 23 can be set according to the width of the part to be fixed along the second direction B. In order to fix multiple GPU cards at the same time, multiple slots 23 can be arranged along the longitudinal interval, and each slot 23 corresponds to a GPU card. When fixing multiple GPU cards by this fixing structure, the baffle 3 can be rotated to the second position first, and multiple GPU cards can be inserted into the accommodating cavity 13 in turn along the second direction B and engaged with the slot 23. After the insertion is completed, the baffle 3 can be rotated to the first position, and there is no need to put the hand into the narrow accommodating cavity 13. When fixing multiple GPU cards, this fixing structure is not limited by space and is easy to operate.

[0047] In some embodiments, the fixing structure also includes: a first flange 24, which is arranged on the side of the bracket 2 close to the mounting surface 11, and the first flange 24 is provided with at least one snap-in groove 241 with an opening; and at least one snap-in column 111, which is arranged on the mounting surface 11 and at least one snap-in column 111 corresponds to and adapts to the snap-in groove 241.

[0048] Specifically, Figure 1 As shown, in order to facilitate the installation of the fixed bracket 2 on the mounting surface 11, the fixing structure also includes a clamping groove 241 and a clamping column 111. The clamping groove 241 is arranged on the first flange 24 on the side of the bracket 2 close to the mounting surface 11. The extension direction of the first flange 24 is parallel to the mounting surface 11. The first flange 24 is arranged to increase the contact area between the bracket 2 and the mounting surface 11 and improve the overall stability. The clamping groove 241 is provided with an opening, and the width of the opening can be smaller than the diameter of the clamping column 111 to prevent the clamping column 111 from slipping out after being clamped into the clamping groove 241 and subjected to external force. During actual installation, the operator first aligns the bracket 2 with the corresponding position on the mounting surface 11, and then gently pushes the bracket 2 along the first direction A, so that the clamping column 111 gradually approaches and finally passes through the opening of the clamping groove 241 and enters the groove. Once the clamping column 111 is fully embedded in the clamping groove 241, since the size of the clamping column 111 matches the size of the groove, the bracket 2 will be firmly fixed on the mounting surface 11 without the need for additional fixings such as screws. This design simplifies the installation steps, and can achieve a quick connection between the bracket 2 and the mounting surface 11 by simply aligning and pushing. If the bracket 2 needs to be adjusted or removed, only the reverse operation is required, that is, the bracket 2 is pulled out in the opposite direction.

[0049] In some embodiments, the fixing structure also includes: a second flange, which is provided at the end of the bracket 2 away from the mounting surface 11, and the second flange extends in a direction away from the accommodating cavity 13; and a clamping portion 34, wherein the end of the baffle 3 corresponding to the second flange is bent toward the side of the baffle 3 close to the mounting surface 11 to form a clamping portion 34, and the clamping portion 34 includes a groove adapted to the second flange to limit the baffle 3 to the bracket 2 when the baffle 3 is in the first position.

[0050] Specifically, Figure 2As shown, the end of the bracket 2 away from the mounting surface 11 is provided with a second flange, and the second flange extends in a direction away from the accommodating cavity 13. The clamping portion 34 is provided on the baffle 3, and the clamping portion 34 is provided with a groove adapted to the second flange for clamping the second flange. In this embodiment, when the baffle 3 rotates clockwise to the first position, the second flange is naturally clamped in the groove of the clamping portion 34. When the baffle 3 rotates from the first position to the second position, the clamping portion 34 is disengaged from the second flange as the baffle 3 rotates, thereby unlocking the fixation of the baffle 3. The clamping portion 34 cooperates with the second flange to evenly distribute the thrust of the second direction B received by the baffle 3 to the entire baffle 3, which can effectively avoid damage to the baffle 3 caused by local stress concentration. At the same time, the structure also limits the baffle 3 from continuing to rotate in the clockwise direction, ensuring that the baffle 3 is fixed in the first position.

[0051] In some embodiments, the fixing structure further includes: at least one ventilation hole 26, which is disposed on the bracket 2 and penetrates the bracket 2 along the first direction A.

[0052] Specifically, Figure 1-Figure 3 As shown, in order to dissipate the heat generated by the GPU card out of the accommodating cavity 13, the bracket 2 is provided with a plurality of ventilation holes 26, the shape and size of which can be set according to actual needs and are not specifically limited here. The provision of the ventilation holes 26 not only facilitates ventilation but also helps the operator to observe the installation status through the ventilation holes 26 when inserting the GPU card.

[0055] The present application provides a riser bracket 2, comprising the fixing structure as described above. Figure 1As shown, the riser bracket 2 includes a locking structure 4, which includes a base 41 and a locking piece 42. The locking piece 42 can be a plate-like structure. The base 41 is fixed to the side of the short side of the fixing frame 1 away from the mounting surface 11. The side of the base 41 away from the fixing surface 12 is provided with a locking piece 42. The locking piece 42 is rotatably connected to the base 41, and its rotation axis is perpendicular to the mounting surface 11. When the locking piece 42 rotates to the point where its extension direction is parallel to the long side of the fixing frame 1, the locking piece 42 cooperates with the baffle 3 to limit the position of the part to be fixed in the first direction A. When the riser bracket 2 fixes the part to be fixed, it only needs to push the part to be fixed into the fixing frame 1 along the second direction B, and then the baffle 3 cooperates with the fixing frame 1 to clamp the two ends of the part to be fixed along the second direction B. The operation is simple and convenient, and the operation space is not limited.

When the baffle 3 is in the first position, the baffle 3 cooperates with the fixing frame 1 and is clamped at both ends of the part to be fixed along the second direction B to limit the position of the part to be fixed in the second direction B. The bracket 2 cooperates with the fixing frame 1 and is clamped at both ends of the part to be fixed along the first direction A to limit the position of the part to be fixed in the first direction A, thereby locking the part to be fixed to the fixing frame 1. When the baffle 3 is in the second position, the baffle 3 releases the clamping of the part to be fixed, and at this time, the part to be fixed can be pulled out of the fixing frame 1 along the second direction B.
