It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0045] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0046] According to the inventive concept of one aspect of the present disclosure, there is provided an installation device for an expansion card, the installation device comprising: a base, suitable for being installed inside a server; a board, installed at the bottom of the base, suitable for plugging in the expansion card; a first limit portion, installed on the base, movable along a first direction between a first position close to the board and a second position away from the board; and a second limit portion, installed on the first limit portion, moving with the first limit portion, and the second limit portion being configured to be adjustable in a second direction, so as to lock the expansion card on the base when the first limit portion is in a first position and the second limit portion corresponds to the expansion card in the second direction; wherein the second direction is orthogonal to the first direction.

[0047] Figure 1 A schematic perspective view of a mounting device for an expansion card according to an embodiment of the present disclosure is shown; Figure 2 The moving directions of the first limiting portion and the second limiting portion of the installation device for the expansion card according to the embodiment of the present disclosure are schematically shown.

[0048] According to an exemplary embodiment of the present disclosure, please refer to Figure 1-Figure 2, provides an installation device for an expansion card. The installation device includes a base 1, a board 2, a first limit portion 4 and a second limit portion 5. The base 1 is suitable for installation inside a server. The board 2 is installed at the bottom of the base 1 and is suitable for plugging in the expansion card 3. The first limit portion 4 is installed on the base 1 and can move between a first position close to the board 2 and a second position away from the board 2 along a first direction. The second limit portion 5 is installed on the first limit portion 4, moves with the first limit portion 4, and the second limit portion 5 is configured to be adjustable in the second direction, so as to lock the expansion card 3 on the base 1 when the first limit portion 4 is in the first position and the second limit portion 5 corresponds to the expansion card 3 in the second direction. Wherein, the second direction is orthogonal to the first direction.

[0049] It should be noted that, in this embodiment, the first direction refers to Figure 2 The direction indicated by the arrow X in the middle, the second direction refers to Figure 2 The direction indicated by arrow Y.

[0050] In this embodiment, the first limiting portion 4 is installed on the base 1, and the first limiting portion 4 can be along a first direction, that is, a transverse direction, such as Figure 2 The second limiting portion 5 is mounted on the first limiting portion 4 and moves with the first limiting portion 4. The second limiting portion 5 is configured to move in the second direction, i.e., the longitudinal direction, as shown in the arrow X. Figure 2 That is, the direction indicated by the middle arrow Y can be adjusted so that when the first limiting portion 4 is in the first position and the second limiting portion 5 corresponds to the expansion card 3 in the second direction, the expansion card 3 can be locked on the base 1, so as to be suitable for locking the expansion card 3 with different sizes in the first direction (i.e., the lateral direction) and in the second direction (i.e., the height direction) on the base 1.

[0051] Figure 3 An exploded view of a mounting device for an expansion card according to an embodiment of the present disclosure is schematically shown.

[0052] In some exemplary embodiments, referring to Figure 1 as well as Figure 3 The first limiting portion 4 includes a first slide rail 41 and a first slider 42. The first slide rail 41 is detachably mounted on the base 1 and has at least two mounting positions along a first direction relative to the base 1. The first slider 42 is slidably mounted on the first slide rail 41, so that when the first slide rail 41 is in the mounting position close to the expansion card 3, it is adjusted to the first position to press against the side of the expansion card 3.

[0053] In this embodiment, along the first direction (i.e., the transverse direction), the first slide rail 41 has a plurality of installation positions relative to the base 1, and each installation position corresponds to a transverse distance between the first slider 42 and the expansion card 3 in the first direction. Therefore, when the first slide rail 41 is installed at different installation positions, the corresponding different transverse distances are adapted to the first slider 42 pressing against the expansion cards 3 with different sizes in the first direction. In other words, the first slide rail 41 has a plurality of installation positions relative to the base 1, forming a plurality of corresponding transverse distances, so as to adapt to the first slider 42 pressing against the expansion cards 3 with different sizes in the first direction.

[0054] Furthermore, the size of some new expansion cards 3 in the first direction (i.e., the lateral direction) does not satisfy any of the multiple installation positions of the first slide rail 41 relative to the base 1. For such new expansion cards 3, in this embodiment, the first slider 42 is slidably installed on the first slide rail 41 along the first direction, so that the distance between the first slider 42 and the expansion card 3 in the first direction is continuously adjustable in the partial area of ​​the first slide rail 41 extending into the base 1, so as to adapt to the first slider 42 to abut against the expansion card 3 whose size in the first direction has changed, so as to meet the need of limiting the new expansion card 3 in the first direction.

[0055] Figure 4 A top view of a substrate of a mounting device for an expansion card according to an embodiment of the present disclosure is schematically shown.

[0056] In some exemplary embodiments, referring to Figure 3-Figure 4 The base 1 has a mounting hole group 11 corresponding to the number of the first slide rail 41, each group includes at least two mounting holes 111, and the at least two mounting holes 111 in the same group are arranged at intervals along the first direction, and each mounting hole 111 is used as a mounting position of the first slide rail 41. The first limiting portion 4 also includes a first connecting member 43, which is detachably arranged in the mounting hole 111 and penetrates the first slide rail 41 in a state of being assembled with the mounting hole 111, so as to keep the first slide rail 41 in the installed position.

[0057] In this embodiment, a mounting hole group 11 corresponding to the number of the first slide rails 41 is formed on the base 1, which can be adapted to the case where the mounting device includes a first limiting portion 4, by changing the mounting hole group 11 installed with the first limiting portion 4 to change the installation position of the first limiting portion 4 in the third direction (i.e., the longitudinal direction), thereby adapting to the plug-in terminal 21 installed at different positions on the board 2 in the third direction.

[0058] Furthermore, the first connecting member 43 can be a bolt or a screw. When the first limiting portion 4 is pressed against the side of the expansion card 3, the first connecting member 43 passes through the first slide rail 41 and the corresponding mounting hole 111 in sequence, and the first slide rail 41 is kept in the mounting position by rotating the first connecting member 43.

[0059] Figure 5 Schematically shows Figure 1 A partial enlarged view of part A.

[0060] In some exemplary embodiments, referring to Figure 1 , Figure 3 as well as Figure 5 The first limiting portion 4 further includes a second connecting member 44 , which is detachably disposed on the first slider 42 and, when assembled on the first slider 42 , presses against the first slide rail 41 to limit the first slider 42 from sliding relative to the first slide rail 41 .

[0061] In this embodiment, each first slide rail 41 is formed with first folded edges 411 at the top of two side walls facing each other in the third direction (i.e., the longitudinal direction). The two first folded edges 411 extend facing each other. The second connecting member 44 passes through the first slider 42 along the second direction (i.e., the height direction) and is threadedly connected to the first slider 42. The end of the second connecting member 44 abuts against the first slide rail 41. By rotating the second connecting member 44, the first slider 42 is pressed against the two first folded edges 411, thereby limiting the sliding of the first slider 42 relative to the first slide rail 41.

[0062] Furthermore, the second connecting member 44 can be a bolt or a screw. When the first limiting portion 4 is in a state of being pressed against the side of the expansion card 3, the second connecting member 44 is rotated to drive the first slider 42 to move toward the two first folded edges 411, so that the first slider 42 is squeezed on the two first folded edges 411 to limit the sliding of the first slider 42 relative to the first slide rail 41.

[0063] In some exemplary embodiments, referring to Figure 2 The installation device includes at least two first limiting portions 4, which are spaced apart along the third direction, and each first limiting portion 4 is pressed against a side of an expansion card 3. The third direction is orthogonal to both the first direction and the second direction.

[0064] It should be noted that, in this embodiment, the third direction refers to Figure 2 The direction indicated by the arrow Z.

[0065] In this embodiment, the mounting device includes a plurality of first limiting portions 4, and the plurality of first limiting portions 4 are arranged along a third direction, that is, a longitudinal direction. Figure 2In the direction indicated by the middle arrow Z, the first limiting portion 4 is arranged at intervals on the base 1. Each first limiting portion 4 is pressed against the side of a corresponding expansion card 3 to meet the need of sequentially locking multiple expansion cards 3 in the third direction. Further, by adjusting the spacing between each first limiting portion 4 and the corresponding expansion card 3 in the first direction, the need of pressing multiple expansion cards 3 with different sizes in the first direction can be met.

[0066] In some exemplary embodiments, referring to Figure 1 as well as Figure 3 The first slider 42 is provided with a second slide rail 45 extending along the second direction. The second stopper 5 is slidably provided on the second slide rail 45 to press against the top of the expansion card 3 when the second stopper 5 corresponds to the expansion card 3 .

[0067] In this embodiment, a second slide rail 45 extending along the second direction (i.e., the height direction) is formed on the first slider 42, and the second limiting portion 5 is slidably installed on the second slide rail 45. When the second limiting portion 5 corresponds to the expansion card 3, the second limiting portion 5 is pressed against the top of the expansion card 3.

[0068] Figure 6 Schematically shows Figure 1 A partial enlarged view of part B.

[0069] In some exemplary embodiments, referring to Figure 1 , Figure 3 as well as Figure 6 The second limiting portion 5 includes a second slider 51 and a third connecting member 52. The third connecting member 52 is detachably disposed on the second slider 51, and when assembled on the second slider 51, presses against the second slide rail 45 to limit the second slider 51 from sliding relative to the second slide rail 45.

[0070] It should be noted that, in this embodiment, the ends of the two side walls of the second slide rail 45 facing each other in the third direction (i.e., the longitudinal direction) are respectively formed with second folded edges 451. The two second folded edges 451 extend facing each other. The third connecting member 52 extends into one end of the second slide rail 45 through the second slider 51 along the first direction (i.e., the transverse direction) and is threadedly connected to the second slide rail 45. The end of the third connecting member 52 abuts against the second slide rail 45, and the second slider 51 is pressed against the two second folded edges 451 by rotating the third connecting member 52, thereby limiting the sliding of the second slider 51 relative to the second slide rail 45.

[0071] Furthermore, the third connecting member 52 can be a bolt or a screw. When the first limiting portion 4 is pressed against the side of the expansion card 3 and the second limiting portion 5 is pressed against the top of the expansion card 3, the third connecting member 52 is rotated to drive the second slider 51 to move toward the two second folded edges 451, so that the second slider 51 is squeezed on the two second folded edges 451 to limit the sliding of the second slider 51 relative to the second slide rail 45.

[0072] In some exemplary embodiments, referring to Figure 3 The second slider 51 includes a mounting end 511 and a limiting end 512. The mounting end 511 is slidably disposed on the second slide rail 45. The limiting end 512 is disposed at an end of the mounting end 511 away from the second slide rail 45, and extends along the first direction toward a side close to the expansion card 3 to press against the top of the expansion card 3.

[0073] In this embodiment, the limit end 512 and the mounting end 511 are interconnected to form a roughly L-shape, and the mounting end 511 can be slidably installed on the second slide rail 45, so that when the limit end 512 is in a state of pressing against the top of the expansion card 3, the expansion card 3 is locked on the base 1.

[0074] In other words, when the second slide rail 45 is pressed against the side of the expansion card 3 and the limit end 512 is pressed against the top of the expansion card 3, the third connecting member 52 passes through the mounting end 511 of the second slider 51 and abuts against the second slide rail 45, and the third connecting member 52 is rotated to drive the second slider 5 to move toward the two second folded edges 451, so that the mounting end 511 of the second slider 51 is squeezed on the two second folded edges 451 to limit the movement of the second slider 51 relative to the second slide rail 45.

[0075] Figure 7 The diagram schematically shows the state of the second slider of the installation device for expansion card locking or releasing the board card according to the embodiment of the present disclosure.

[0076] In some exemplary embodiments, referring to Figure 1 as well as Figure 7 The second slider 51 is made of elastic material, and the limiting end 512 is configured to bend along the first direction toward a side away from the expansion card 3 in response to external pressure to break away from the top of the expansion card 3.

[0077] In this embodiment, the second slider 51 is made of elastic material, so that the second slider 51 forms a roughly L-shaped elastic arm, so that the second slider 51 has a bending state in which it is bent toward the side away from the expansion card 3 in the first direction (i.e., the lateral direction), and a locking state in which it is pressed against the side and top of the expansion card 3 to release or lock the expansion card 3.

[0078] Through the above arrangement, when replacing an expansion card 3 of the same size, for example, replacing an expansion card 3 of the same model, the operator only needs to move the second slider 51 toward the side away from the expansion card 3. Figure 7 In the state shown by the arrow M in the middle, the second slider 51 releases the expansion card 3. At this time, the operator can remove the expansion card 3 from the plug-in end 21 of the board 2, and install another expansion card 3 of the same model on the plug-in end 21 of the board 2, and release the second slider 51, so that the second slider 51 presses against the side and top of the expansion card 3, as shown in FIG. Figure 7 The state shown by the arrow N in the middle is thus completed to replace the expansion card 3. Therefore, when replacing the expansion card 3 of the same model, it is not necessary to adjust the relative positions between the first limiting portion 4 and the second limiting portion 5 and the expansion card 3, which is convenient for operation.

[0079] In some exemplary embodiments, referring to Figure 1 as well as Figure 3 The base 1 includes a base plate 12 and a first side plate 13 and a second side plate 14 facing each other. The base plate 12 is suitable for being installed inside the server. The first side plate 13 and the second side plate 14 facing each other are respectively installed on both sides of the base plate 12 extending in the lateral direction. A connecting arm 131 is formed on the first side plate 13 to limit the movement of the expansion card 3. A notch 141 is formed on the second side plate 14 to allow the first limit portion 4 to extend into the base 1.

[0080] It should be noted that, in this embodiment, the number of the connecting arms 131 formed on the first side plate 13 should be the same as the number of the expansion cards 3 . Similarly, the number of the notches 141 formed on the second side plate 14 should be the same as the number of the first limiting portions 4 .

[0081] Furthermore, in the present embodiment, it should be noted that at least one plug-in terminal 21 suitable for connecting to the expansion card 3 is sequentially arranged along the third direction (i.e., the longitudinal direction) on the upper side of the board 2, and each plug-in terminal 21 may correspond to a set of mutually combined first limiting portions 4 and second limiting portions 5, so as to be adapted to locking and installing a plurality of expansion cards 3 having different sizes in the first direction (i.e., the lateral direction) and in the second direction (i.e., the height direction) on the base 1.

[0082] According to an exemplary embodiment of the present disclosure, a chassis is provided, comprising the installation device for an expansion card described in the above embodiment, wherein the installation device is installed inside the chassis.

[0083] The chassis may be a server, a cabinet or other independent computing units.

[0084] The installation device for expansion card disclosed in the present invention has the following advantages:

[0085] 1. Through the cooperation of the first limiting portion 4 and the second limiting portion 5 on the base 1, the first limiting portion 4 can move along the first direction (i.e., the transverse direction) between a first position close to the board 2 and a second position away from the board 2, and the second limiting portion 5 moves with the first limiting portion 4 and is adjustable in the second direction (i.e., the height direction), so that when the first limiting portion 4 is in a state of pressing the side of the expansion card 3 in the first direction and the second limiting portion 5 is in a state of pressing the top of the expansion card 3 in the second direction, the expansion card 3 is locked on the base 1, so as to be suitable for locking the expansion card 3 with different sizes in the first direction (i.e., the transverse direction) and in the second direction (i.e., the height direction) on the base 1.

[0086] 2. When the size of the expansion card 3 in the first direction (i.e., the lateral direction) satisfies one of the multiple installation positions of the first slide rail 41 relative to the base 1 and forms a plurality of corresponding lateral spacings, there is no need to adjust the relative position of the first slider 42 relative to the first slide rail 41.

[0087] Further, when the first slide rail 41 has multiple installation positions relative to the base 1 and forms multiple corresponding lateral spacings that cannot meet the size of the expansion card 3 in the first direction, the first slider 42 can be moved inside the first slide rail 41 so that the second slide rail 45 presses against the side of the expansion card 3, thereby locking the expansion card 3 on the base 1 in the first direction.

[0088] 3. When the size of the expansion card 3 in the first direction (i.e., the lateral direction) changes slightly, it is not necessary to adjust the relative position between the first slide rail 41 and the base 1. It is only necessary to move the first slider 42 inside the first slide rail 41 and adjust the relative position of the first slider 42 to the expansion card 3 in the first direction so that the second slide rail 45 moves to a position pressed against the side of the expansion card 3, thereby simplifying the operation process and facilitating operation.

[0089] 4. When replacing an expansion card 3 of the same size, i.e., an expansion card 3 of the same model, the operator only needs to move the second slider 51 toward the side away from the expansion card 3 so that the second slider 51 releases the expansion card 3. At this time, the operator can remove the expansion card 3 from the plug-in end 21 of the board 2, and install another expansion card 3 of the same model on the plug-in end 21 of the board 2, and release the second slider 51 so that the second slider 51 presses against the side and top of the expansion card 3, and the expansion card 3 can be replaced. Therefore, when replacing an expansion card 3 of the same model, it is not necessary to adjust the relative positions between the first limiting portion 4 and the second limiting portion 5 and the expansion card 3, which is convenient for operation.

[0090] Furthermore, the working principle of the installation device for expansion card disclosed in the present invention is as follows:

[0091] First, the expansion card 3 is plugged into the corresponding plug-in terminal 21 on the board 2 .

[0092] Second, the operator rotates the first connecting member 43 so that the first connecting member 43 is disengaged from the base 1, aligns the first slide rail 41 with the expansion card 3 in the third direction (i.e., the longitudinal direction), and moves the first slide rail 41 in the first direction (i.e., the lateral direction) to an installation position closer to the expansion card 3, and passes the first connecting member 43 through the installation hole 111 corresponding to the installation position and the first slide rail 41 to install the first slide rail 41 on the base 1 to limit the relative position between the first slide rail 41 and the base 1.

[0093] Third, move the first slider 42 inside the first slide rail 41 so that the second slide rail 45 moves to a position pressed against the side of the expansion card 3, and rotate the second connecting member 44 to drive the first slider 42 to move toward the two first folded edges 411, so that the first slider 42 is squeezed on the two first folded edges 411 to limit the movement of the first slider 42 relative to the first slide rail 41, so as to lock the expansion card 3 in the first direction.

[0094] Fourth, move the second slider 51 inside the second slide rail 45 so that the limit end 512 of the second slider 51 moves to a position pressed against the top of the expansion card 3, and rotate the third connecting member 52 to drive the second slider 51 to move toward the two second folded edges 451, so that the second slider 51 is squeezed on the two second folded edges 451 to limit the movement of the second slider 51 relative to the second slide rail 45, so as to lock the expansion card 3 in the second direction (i.e., the height direction).

[0095] In other words, the second slider 51 is moved inside the second slide rail 45 so that the limiting end 512 of the second slider 51 moves to a position pressed against the top of the expansion card 3, the third connecting member 52 is passed through the mounting end 511 of the second slider 51 and is abutted against the second slide rail 45, and the third connecting member 52 is rotated to drive the second slider 5 to move toward the two second folded edges 451, so that the mounting end 511 of the second slider 51 is squeezed on the two second folded edges 451 to limit the movement of the second slider 51 relative to the second slide rail 45 in the second direction.

[0096] In addition, it should be noted that when replacing an expansion card 3 of the same size, that is, an expansion card 3 of the same model, the operator of the installation device for expansion cards disclosed in the present invention only needs to move the second slider 51 toward the side away from the expansion card 3 so that the second slider 51 releases the expansion card 3. At this time, the operator can remove the expansion card 3 from the plug-in end 21 of the board 2, and install another expansion card 3 of the same model on the plug-in end 21 of the board 2, and release the second slider 51 so that the second slider 51 presses against the side and top of the expansion card 3 to complete the replacement of the expansion card 3. Therefore, when replacing an expansion card 3 of the same model, it is not necessary to adjust the relative position between the first limiting portion 4 and the second limiting portion 5 and the expansion card 3, which is convenient for operation.
