Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a fixing mechanism and a server. Background Art

[0002] An expansion card is usually installed on a server to expand the memory of an electronic device. In order to firmly fix the expansion card to the server, currently, the expansion card is first installed in the slot of the server and then fixed with screws. When the expansion card needs to be replaced, the screws must be removed with a tool and then the expansion card is removed from the slot. However, the existing method of disassembling and installing the expansion card is not convenient for users to operate. Summary of the invention

[0003] In view of this, it is necessary to provide a fixing mechanism and a server, which can improve the convenience of installing the expansion card on the server.

[0004] The embodiment of the present application provides a fixing mechanism applied to a server, including a shell, a fixing member and a sliding member, wherein the shell is used to accommodate an expansion card. The fixing member is slidably arranged on the shell and can be connected to the expansion card. The sliding member is slidably arranged on the shell and can slide along a first direction and a direction opposite to the first direction, wherein the first direction is the direction in which the expansion card enters the shell, and the sliding member is provided with a first supporting portion and a second supporting portion that are connected, and part of the fixing member is connected to the first supporting portion or the second supporting portion to lock the expansion card in the shell or unlock it from the shell. When the fixing member is connected to the first supporting portion, the fixing member forms a limiting fit with the first limiting portion on the expansion card, and the fixing mechanism locks the expansion card. When part of the fixing member is connected to the second supporting portion, the fixing member is disengaged from the first limiting portion, and the fixing mechanism unlocks the expansion card.

[0005] In the above-mentioned fixing mechanism, when part of the fixing member is connected to the second supporting portion, the fixing member unlocks the expansion card, and the expansion card can be placed in or taken out of the shell; when part of the fixing member is connected to the first supporting portion, the fixing member can form a limit fit with the expansion card, thereby limiting the movement of the expansion card, thereby improving the installation stability of the expansion card. In addition, by driving the sliding member to slide, part of the fixing member can be connected to the first supporting portion or the second supporting portion of the sliding member, so that the fixing member can lock the expansion card to the shell or make the fixing member away from the first limiting portion, so that the expansion card can be moved. In this solution, the fixing member can be switched between the locked state and the unlocked state only by driving the sliding member to move, without the assistance of other tools, thereby facilitating the installation of the expansion card on the fixing mechanism, thereby improving the convenience of installing the expansion card on the server.

[0006] In at least one embodiment, the fixing mechanism further includes a rotating member, one end of the rotating member is rotatably connected to the shell, and the other end of the rotating member is rotatably connected to the sliding member, and the rotating member can drive the sliding member to slide on the shell.

[0007] In the above embodiment, the rotating member can drive the sliding member to slide on the housing along the first direction or the opposite direction of the first direction through the rotation of the rotating member, so that the sliding member drives the fixing member to switch between the state of locking the expansion card and the state of unlocking the expansion card, thereby facilitating user operation.

[0008] In at least one embodiment, the fixing mechanism further includes a pushing assembly, which is movably connected to the sliding member and the housing, respectively. When the sliding member slides along the first direction, part of the fixing member can switch from being connected to the first support portion to being connected to the second support portion, and the sliding member can drive the pushing assembly to move.

[0009] In the above embodiment, when the sliding member slides in the unlocking direction of the fixing member, that is, when the sliding member slides in the first direction, the fixing member can be converted into a state of unlocking the expansion card, that is, the expansion card can be taken out of the housing. At the same time, the sliding member also drives the pushing component to move, so that the pushing component pushes the expansion card in the opposite direction of the first direction, thereby making one end of the expansion card first exposed outside the housing, which is conducive to taking the entire expansion card out of the housing.

[0010] In at least one embodiment, the pushing assembly includes a first connecting rod, a second connecting rod and a pushing portion, one end of the first connecting rod is hinged to one end of the second connecting rod, the other end of the first connecting rod is rotatably connected to the sliding member, and can slide relative to the sliding member in a second direction or in a direction opposite to the second direction, and the second direction is perpendicular to the first direction. The other end of the second connecting rod is rotatably connected to the pushing portion, and the pushing portion is slidably disposed on the housing, the pushing portion can slide in the first direction or in a direction opposite to the first direction, and the pushing portion is used to push the expansion card to make the expansion card slide in a direction opposite to the first direction.

[0011] In the above embodiment, when the sliding member slides along the first direction, one end of the first connecting rod slides relative to the sliding member along the second direction or the opposite direction of the second direction, and the first connecting rod rotates relative to the sliding member, thereby causing the second connecting rod to rotate relative to the first connecting rod, and the second connecting rod drives the pushing portion to slide in the opposite direction of the first direction, so that the pushing portion can push the expansion card out of the shell to facilitate the separation of the expansion card from the shell.

[0012] In at least one embodiment, the fixing mechanism further includes an elastic reset member, which is respectively connected to the fixing member and the housing. When part of the fixing member is connected to the second supporting portion, the elastic reset member is stretched to have elastic force, and the stretched elastic reset member can drive the fixing member to slide in a direction to form a limiting fit with the first limiting portion.

[0013] In the above embodiment, when the fixing member is in the state of unlocking the expansion card, the expansion card can enter the housing, and at this time the fixing member does not form a limiting fit with the first limiting portion. When the expansion card slides along the first direction to the first limiting portion close to the fixing member, and the fixing member is not restricted by other external forces, the elastic force of the elastic reset member can make the fixing member slide in the direction of forming a limiting fit with the first limiting portion, thereby improving the tightness of the fit between the fixing member and the first limiting portion.

[0014] In at least one embodiment, the fixing member includes a mounting portion and a second limiting portion, the mounting portion is slidably disposed on the housing, the mounting portion is connected to the first supporting portion or the second supporting portion, and the second limiting portion is used to form a limiting match with the first limiting portion on the expansion card to lock the expansion card. The second limiting portion has a guide block, and the guide block gradually narrows in the opposite direction of the second direction, and the second direction is the sliding direction when the fixing member unlocks the expansion card.

[0015] In the above embodiment, when the expansion card enters the shell, the end of the expansion card that first enters the shell can first contact the guide block, so that the guide block of the second limit portion can be pushed by the expansion card, so that the second limit portion slides in the second direction, so that the second limit portion cannot block the expansion card from entering the shell. When the first limit portion of the expansion card slides to a position corresponding to the second limit portion, the guide block of the second limit portion is no longer pushed by the expansion card, and the first limit portion and the guide block of the second limit portion form a limit fit. This arrangement allows the expansion card to be directly installed into the shell along the first direction without any operation on the fixing mechanism when the expansion card is installed into the shell.

[0016] In at least one embodiment, the housing has two opposite inner wall surfaces, each inner wall surface is provided with a track member, and the track member is arranged along a first direction for accommodating an expansion card.

[0017] In the above embodiment, when the expansion card is installed into the shell, it can enter the shell along the setting direction of the track member. The track member can not only provide guidance for the installation and removal of the expansion card, but also support and limit the expansion card, so that the expansion card is not easy to move in the shell.

[0018] In at least one embodiment, the shell has two opposite first outer walls, two sliding members are provided, one sliding member is provided on each first outer wall, each sliding member is provided with at least one fixing member, and the fixing members on the two sliding members are used to fix different expansion cards.

[0019] In the above embodiment, the housing can accommodate multiple expansion cards at the same time, and each expansion card is provided with a corresponding fixing member, and the fixing members on different sliding members can fix multiple expansion cards at the same time.

[0020] In at least one embodiment, the shell has a first connection part, the sliding member has a second connection part, the first connection part is movably connected to the second connection part, and the second connection part can slide relative to the first connection part along a first direction or a direction opposite to the first direction.

[0021] In the above embodiment, when the first connection part slides relative to the second connection part, the sliding member can slide, thereby causing the sliding member to drive the fixing member to move. In addition, the first connection part and the second connection part can provide guidance and support for the sliding of the sliding member, thereby improving the stability of the sliding member movement.

[0022] An embodiment of the present application further provides a server, comprising a casing and any one of the above-mentioned fixing mechanisms, wherein the fixing mechanism is arranged in the casing.

[0023] In the above embodiment, after the expansion card is installed in the housing, the first limit portion of the expansion card can form a limit fit with the fixing member to limit the movement of the expansion card, thereby improving the stability of the expansion card installed in the housing. In addition, the fixing mechanism can lock and unlock the expansion card by driving the sliding member to slide, thereby improving the convenience of installing the expansion card.

[0081] The embodiment of the present application provides a fixing mechanism, which is applied to a server. The fixing mechanism includes a housing, a fixing member and a sliding member. The housing is used to accommodate an expansion card. The fixing member is slidably arranged on the housing and can be connected to the expansion card. The sliding member is slidably arranged on the housing and can slide along a first direction and a direction opposite to the first direction. The first direction is the direction in which the expansion card enters the housing. The sliding member is provided with a first supporting portion and a second supporting portion that are connected. Part of the fixing member is connected to the first supporting portion or the second supporting portion to lock the expansion card in the housing or unlock it from the housing. When the fixing member is connected to the first supporting portion, the fixing member forms a limiting fit with the first limiting portion on the expansion card, and the fixing mechanism locks the expansion card. When part of the fixing member is connected to the second supporting portion, the fixing member is disengaged from the first limiting portion, and the fixing mechanism unlocks the expansion card.

[0082] In the above-mentioned fixing mechanism, when part of the fixing member is connected to the second supporting portion, the fixing member unlocks the expansion card, and the expansion card can be placed in or taken out of the shell; when part of the fixing member is connected to the first supporting portion, the fixing member can form a limit fit with the expansion card, thereby limiting the movement of the expansion card, thereby improving the installation stability of the expansion card. In addition, by driving the sliding member to slide, part of the fixing member can be connected to the first supporting portion or the second supporting portion of the sliding member, so that the fixing member can lock the expansion card to the shell or make the fixing member away from the first limiting portion, so that the expansion card can be moved. In this solution, the fixing member can be switched between the locked state and the unlocked state only by driving the sliding member to slide, without the assistance of other tools, thereby facilitating the installation of the expansion card on the fixing mechanism, thereby improving the convenience of installing the expansion card on the server.

[0083] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0084] like Figure 1 and Figure 2As shown, an embodiment of the present application provides a server 200 , which includes a housing 21 and a fixing mechanism 100 . The fixing mechanism 100 is disposed in the housing 21 and is used to lock or unlock an expansion card 22 .

[0085] In one embodiment, the expansion card 22 is provided with a first limiting portion 221, and the first limiting portion 221 is used to form a limiting match with the fixing mechanism 100. For example, the first limiting portion 221 is provided at the edge of the expansion card 22, and when the expansion card 22 is installed in the fixing mechanism 100, the first limiting portion 221 can form a limiting match with the fixing mechanism 100, so that the fixing mechanism 100 can lock the expansion card 22.

[0086] The expansion card 22 forms a limiting fit with the fixing mechanism 100 via the first limiting portion 221 to limit the movement of the expansion card 22 in the fixing mechanism 100 , thereby improving the installation stability of the expansion card 22 on the server 200 .

[0087] See also Figure 2 and Figure 3 The embodiment of the present application further provides a fixing mechanism 100, which is applied to a server 200. The fixing mechanism 100 includes a housing 11, a fixing member 12 and a sliding member 13. The housing 11 is used to accommodate an expansion card 22. The fixing member 12 is slidably disposed on the housing 11 and can be connected to the expansion card 22. The sliding member 13 is slidably disposed on the housing 11 and can drive the fixing member 12 to slide relative to the housing 11.

[0088] In one embodiment, the sliding member 13 can slide along the first direction X and the direction opposite to the first direction X. The first direction X is the direction in which the expansion card 22 enters the housing 11 . The fixing member 12 can slide along a direction perpendicular to the first direction X.

[0089] The fixing member 12 slides relative to the housing 11 by driving the sliding member 13 to slide, so that the fixing member 12 can form a limiting fit with the first limiting portion 221 on the expansion card 22, thereby fixing the expansion card 22 to the housing 11 of the fixing mechanism 100. No tools are required in the process of fixing the expansion card 22, thereby improving the convenience of installing the expansion card 22.

[0090] See also Figure 2 and Figure 3In one embodiment, the housing 11 includes two first outer walls 111 and one second outer wall 112, the two first outer walls 111 are connected by the second outer wall 112, and the two first outer walls 111 are arranged opposite to each other. The first outer wall 111 and the second outer wall 112 enclose a mutually connected accommodation cavity 113, and the accommodation cavity 113 has an opening 114. The accommodation cavity 113 is used to accommodate the expansion card 22, and the expansion card 22 can enter the accommodation cavity 113 from the opening 114 along the first direction X, or be taken out of the accommodation cavity 113 along the opposite direction of the first direction X. In one embodiment, the two first outer walls 111 are respectively arranged perpendicular to the second outer wall 112.

[0091] In one embodiment, each first outer wall 111 has two opposite inner wall surfaces 1111 . Each inner wall surface 1111 is provided with a track member 115 . The track member 115 is extended along the first direction X for slidingly installing the expansion card 22 .

[0092] For example, the track member 115 is provided with a slide groove for accommodating the expansion card 22, and the track member 115 is fixed on the inner wall surface 1111. The slide groove can also be directly formed on the inner wall surface 1111, for example, by punching a bending piece on the first outer wall 111 into the housing 11. When the expansion card 22 enters the accommodating cavity 113, the two opposite edges of the expansion card 22 can gradually enter the accommodating cavity 113 along the corresponding track member 115. The slide groove can not only provide a guide for the installation and removal of the expansion card 22, but also support and limit the expansion card 22, so that the expansion card 22 is not easy to shake in the housing 11.

[0093] See also Figure 4 and Figure 5 , Figure 5 The internal structure of the housing 11 is shown when the expansion card 22 is not placed in the housing 11. Figure 5 In one embodiment, the track member 115 is provided with an escape hole 1151, and when the first limit portion 221 of the expansion card 22 slides to the position of the escape hole 1151, the fixing member 12 can slide from the escape hole 1151 to snap-fit ​​with the first limit portion 221 on the expansion card 22.

[0094] See also Figure 3 and Figure 5 In one embodiment, each inner wall surface 1111 has at least two track members 115 distributed along the second direction Y, and the at least two track members 115 are parallel to each other. The second direction Y is perpendicular to the first direction X. This arrangement facilitates the housing 11 to accommodate multiple expansion cards 22 .

[0095] See also Figure 5 and Figure 6In one embodiment, the shell 11 has a first connecting portion 116, and the sliding member 13 has a second connecting portion 131. The first connecting portion 116 is movably connected to the second connecting portion 131, and the second connecting portion 131 can slide relative to the first connecting portion 116 along the first direction X or the opposite direction of the first direction X.

[0096] The first connection portion 116 can slide relative to the second connection portion 131 to slide the sliding member 13 on the housing 11 . The first connection portion 116 and the second connection portion 131 can provide guidance and support for the sliding of the sliding member 13 , thereby improving the stability of the movement of the sliding member 13 .

[0097] For example, in one embodiment, the second connection portion 131 is a long hole, the length direction of the long hole is the first direction X, and the first connection portion 116 is a bolt, which is fixed to the outer surface of the housing 11. The bolt is inserted into the long hole and can slide along the length direction of the long hole. The bolt can also be replaced by a screw, a pin, or other parts that can cooperate with the long hole and realize the sliding of the sliding member 13. It can be understood that the first connection portion 116 can also be a long hole, and the second connection portion 131 can be a bolt.

[0098] For another example, in another embodiment, the first connection portion 116 is a guide groove (not shown in the figure), and the second connection portion 131 is a guide post (not shown in the figure). The length direction of the guide groove is consistent with the first direction X, and the guide post is slidably disposed in the guide groove. The sliding of the sliding member 13 relative to the housing 11 is achieved by the sliding of the guide post in the guide groove. Alternatively, the first connection portion 116 is a guide post, and the second connection portion 131 is a guide groove.

[0099] See also Figure 5 and Figure 6 In one embodiment, there are multiple first connection parts 116 and multiple second connection parts 131, and the multiple first connection parts 116 correspond to the multiple second connection parts 131. For example, there are two first connection parts 116 and two second connection parts 131, respectively.

[0100] See also Figure 3 and Figure 4 In one embodiment, the sliding member 13 has a first wall 132 and a second wall 133 that are perpendicular and connected to each other. The first wall 132 is arranged above the second outer wall 112 and is approximately parallel to the second outer wall 112. The upper side is the second direction Y. The second wall 133 is approximately parallel to one of the first outer walls 111 of the shell 11. Approximately parallel refers to the situation that the first wall 132 or the second wall 133 is completely parallel to the second outer wall 112, and the angle between the first wall 132 or the second wall 133 and the second outer wall 112 is within ±5 degrees.

[0101] In one embodiment, the second connection portion 131 is disposed on the second wall 133 , and the first connection portion 116 is disposed on one of the first outer walls 111 of the housing 11 . Alternatively, the second connection portion 131 is disposed on the first wall 132 , and the first connection portion 116 is disposed on the second outer wall 112 of the housing 11 .

[0102] See also Figure 4 , Figure 5 and Figure 6 In one embodiment, the sliding member 13 is provided with a first supporting portion 134 and a second supporting portion 135 that are interconnected to lock the expansion card 22 in the housing 11 or unlock it from the housing 11. When part of the fixing member 12 is connected to the first supporting portion 134, the fixing member 12 forms a limiting fit with the first limiting portion 221 on the expansion card 22. Figure 7 and Figure 8 When part of the fixing member 12 is connected to the second supporting portion 135, the fixing member 12 is separated from the first limiting portion 221, and the fixing mechanism 100 unlocks the expansion card 22. The sliding member 13 can drive the fixing member 12 to switch between the locked state and the unlocked state by sliding itself.

[0103] An inclined surface is formed between the first support portion 134 and the second support portion 135. When part of the fixing member 12 slides from the first support portion 134 to the second support portion 135, part of the fixing member 12 can slide along the inclined surface in the second direction Y, so that the fixing member 12 is lifted during the sliding process, thereby switching the fixing member 12 from a state of locking the expansion card 22 to the shell 11 to a state of unlocking the expansion card 22 from the shell 11.

[0104] By driving the sliding member 13 to slide, the relative positions of the fixing member 12 and the sliding member 13 are changed, so that the fixing member 12 is connected to the first supporting portion 134 or the second supporting portion 135, so that the fixing member 12 can lock the expansion card 22 to the shell 11 or the fixing member 12 is disengaged from the first limiting portion 221, so that the fixing mechanism 100 can unlock the expansion card 22, and the expansion card 22 can be taken out from the shell 11.

[0105] See also Figure 5 , Figure 6 , Figure 7 and Figure 8 , Figure 5 and Figure 6 The figure shows the state when the fixing member 12 is connected to the first supporting portion 134. Figure 7 and Figure 8 The figure shows the state when the fixing member 12 is connected to the second supporting portion 135 . Figure 5 and Figure 7 The structure of the interior of the housing 11 is shown when the expansion card 22 is not placed in the housing 11. Figure 5 and Figure 7The portion blocked by the housing 11 is indicated by a dotted line.

[0106] In one embodiment, the first support portion 134 and the second support portion 135 are two through holes connected to each other on the sliding member 13, the first support portion 134 is a first through hole, and the second support portion 135 is a second through hole. The first through hole and the second through hole are arranged on the second wall 133, and the maximum distance between the inner wall of the first through hole and the second outer wall 112 of the housing 11 is greater than the maximum distance between the inner wall of the second through hole and the second outer wall 112 of the housing 11. Through the sliding of the sliding member 13, the fixing member 12 can slide in the first through hole and the second through hole. When the fixing member 12 is connected to the first through hole, the fixing member 12 is in a state of locking the expansion card 22; when the fixing member 12 is connected to the second through hole, the fixing member 12 is in a state of unlocking the expansion card 22.

[0107] Continue reading Figure 5 , Figure 6 , Figure 7 and Figure 8 In one embodiment, the minimum distance between the first support portion 134 and the second outer wall 112 is equal to the minimum distance between the second support portion 135 and the second outer wall 112, that is, the minimum distance between the inner wall of the first through hole and the second outer wall 112 is equal to the minimum distance between the inner wall of the second through hole and the second outer wall 112. When the mounting portion 122 of the fixing member 12 slides to contact the inner wall of the second through hole near the second outer wall 112, the mounting portion 122 of the fixing member 12 can also be away from the first limiting portion 221. That is, when the fixing member 12 is connected to the first support portion 134, the fixing member 12 can also unlock the expansion card 22. When the expansion card 22 is not placed in the housing 11, the mounting portion 122 of the fixing member 12 is connected to the position of the first through hole away from the second outer wall 112. When the expansion card 22 is to be installed in the housing 11, the fixing member 12 can be slid along the second direction Y to a position where the mounting portion 122 is connected to the first through hole and close to the second outer wall 112, and the expansion card 22 can be installed in the housing 11. After the expansion card 22 is installed in the housing 11, the fixing member 12 is slid along the opposite direction of the second direction Y to a position in the first through hole away from the second outer wall 112, and the expansion card 22 can be locked in the housing 11.

[0108] In this configuration, the fixing member 12 can be unlocked by sliding the fixing member 12 directly so that the fixing member 12 is connected to the position of the first through hole close to the second outer wall 112 without driving the sliding member 13 to slide. Of course, the sliding of the sliding member 13 can also drive the fixing member 12 to slide and connect to the second supporting portion 135 to achieve the unlocking of the expansion card 22 by the fixing member 12.

[0109] In another embodiment, the first support portion 134 and the second support portion 135 may also be slide rails (not shown), and the fixing member 12 may slide along the slide rails so that the fixing member 12 can switch to a state of locking the expansion card 22 or a state of unlocking the expansion card 22 .

[0110] See also Figure 7 , Figure 8 and Fig. 9 , Fig. 9 is a cross-sectional view of the fixing mechanism when the expansion card is placed in the housing, and Fig. 9 for Figure 4 A cross-sectional view along the IX-IX direction in the state. In one embodiment, the fixing member 12 includes a body 121, a mounting portion 122 and a second limiting portion 123, the mounting portion 122 and the second limiting portion 123 are fixedly arranged on the body 121, the mounting portion 122 is slidably arranged on the shell 11, and the second limiting portion 123 is used to form a limiting fit with the first limiting portion 221 on the expansion card 22 to lock the expansion card 22. The mounting portion 122 is connected to the first supporting portion 134 or the second supporting portion 135 so that the second limiting portion 123 forms a limiting fit with the first limiting portion 221 or releases the limiting fit. The body 121 is arranged on the outside of the shell 11, and the second limiting portion 123 penetrates the shell 11 and enters the inside of the shell 11.

[0111] In one embodiment, the mounting portion 122 is cylindrical, one end of the mounting portion 122 is disposed outside the housing 11, and the other end penetrates the housing 11 and is movably connected to the housing 11. The end of the mounting portion 122 disposed outside the housing 11 can be connected to the first support portion 134 or the second support portion 135, so that the second limiting portion 123 forms a limit or releases the limit with the first limiting portion 221. In other embodiments, the mounting portion 122 can also be a slider, and the slider can move along the slide rail.

[0112] See also Figure 2 , Figure 7 , Figure 8 and Fig. 9 In one embodiment, the second limiting portion 123 is a hook, and the first limiting portion 221 is a limiting notch, and the hook can enter or leave the limiting notch to lock or unlock the fixing member 12. In other embodiments, the first limiting portion 221 and the second limiting portion 123 can also be magnetic suction members (not shown in the figure), and when the first limiting portion 221 and the second limiting portion 123 are close to each other, they are attracted to each other to form a lock, and when the first limiting portion 221 and the second limiting portion 123 are away from each other, the lock is released.

[0113] See also Fig. 9In one embodiment, the second limiting portion 123 has a guide block 1231, which gradually narrows in the opposite direction of the second direction Y, and the side of the guide block 1231 used to first contact the expansion card 22 is an inclined surface. The second direction Y is the sliding direction when the fixing member 12 unlocks the expansion card 22, and the second direction Y is perpendicular to the first direction X.

[0114] When the expansion card 22 enters the housing 11, the end of the expansion card 22 that first enters the housing 11 can first contact the inclined surface of the guide block 1231, so that the guide block 1231 of the second limit portion 123 can be pushed by the expansion card 22, so that the second limit portion 123 slides in the second direction Y, so that the first limit portion 221 cannot block the expansion card 22 from entering the housing 11. Fig. 9 As shown in , the end a of the expansion card 22 first contacts the guide block 1231. When the first limit portion 221 of the expansion card 22 slides to a position corresponding to the second limit portion 123, the guide slope of the second limit portion 123 is no longer pushed by the expansion card 22, and the first limit portion 221 forms a limit fit with the second limit portion 123. This arrangement allows the expansion card 22 to be directly installed into the housing 11 along the first direction X without any operation on the fixing mechanism 100 when the expansion card 22 is installed into the housing 11.

[0115] See also Figure 3 and Figure 4 In one embodiment, the fixing mechanism 100 further includes an elastic reset member 14, which is respectively connected to the fixing member 12 and the housing 11. When part of the fixing member 12 is connected to the second support portion 135, the elastic reset member 14 is stretched to have elastic force, and the stretched elastic reset member 14 can drive the fixing member 12 to slide in the direction of forming a limiting fit with the first limiting portion 221. The second direction Y is the sliding direction when the fixing member 12 unlocks the expansion card 22.

[0116] For example, in one embodiment, one end of the elastic reset member 14 is connected to the bottom of the housing 11, and the other end is connected to the bottom of the body 121. When the mounting portion 122 of the fixing member 12 is connected to the second supporting portion 135, the elastic reset member 14 is stretched, and the elastic force generated by the elastic reset member 14 can pull the fixing member 12 in the opposite direction of the second direction Y, so that the fixing member 12 can automatically lock the expansion card 22 when it is not subjected to other external forces. In addition, when the fixing member 12 forms a limiting fit with the first limiting portion 221, that is, when the mounting portion 122 of the fixing member 12 is connected to the first supporting portion 134, the elastic force of the elastic reset member 14 makes the fixing member 12 have a tendency to slide in the direction of forming a limiting fit with the first limiting portion 221, thereby improving the tightness of the fit between the fixing member 12 and the first limiting portion 221.

[0117] It is understandable that in one embodiment, the elastic reset member 14 can be a spring. In other embodiments, the elastic reset member 14 can also be other structures with elastic deformation capability.

[0118] In one embodiment, two sliding members 13 are provided, and the two sliding members 13 are respectively slidably provided on both sides of the shell 11. A sliding member 13 is provided on each first outer wall 111 of the shell 11, and each sliding member 13 is provided with at least one fixing member 12. The fixing members 12 on the two sliding members 13 are used to fix different expansion cards 22.

[0119] The housing 11 can accommodate a plurality of expansion cards 22 at the same time, and each expansion card 22 is provided with a corresponding fixing member 12 . The fixing members 12 on different sliding members 13 can fix the plurality of expansion cards 22 at the same time.

[0120] For example, in one embodiment, two expansion cards 22 can be provided along the second direction Y, and the two expansion cards 22 are distributed in two layers. The fixing member 12 on each first outer wall 111 of the housing 11 can fix one of the expansion cards 22 .

[0121] See also Figure 4 , Figure 5 and Figure 6 In one embodiment, the fixing mechanism 100 further includes a rotating member 15 , one end of the rotating member 15 is rotatably connected to the housing 11 , and the other end of the rotating member 15 is rotatably connected to the sliding member 13 . The rotating member 15 can drive the sliding member 13 to slide on the housing 11 .

[0122] For example, the rotating member 15 includes a rotating portion 151 and an operating portion 152 connected to each other, one end of the rotating portion 151 is rotatably connected to the housing 11, and the other end is rotatably connected to the sliding member 13. Through holes are respectively provided at both ends of the rotating portion 151, the housing 11 is provided with a first rotating shaft 117, the sliding member 13 is provided with a second rotating shaft 118, the second rotating shaft 118 penetrates the sliding member 13, and the rotating portion 151 is rotatably connected to the housing 11 through the first rotating shaft 117. The operating portion 152 is connected to one end of the rotating portion 151, and the rotating portion 151 can be rotated relative to the first rotating shaft 117 by toggling the operating portion 152. At the same time, the operating portion 152 pushes the second rotating shaft 118 during the rotation process to drive the sliding member 13 to slide on the housing 11.

[0123] By rotating the rotating member 15 , the rotating member 15 can drive the sliding member 13 to slide on the housing 11 along the first direction X or the opposite direction of the first direction X, so that the sliding member 13 drives the fixing member 12 to switch between the locked state and the unlocked state, thereby facilitating user operation.

[0124] In one embodiment, the rotating member 15 can drive the sliding member 13 to slide when rotating, thereby making the mounting portion 122 of the fixing member 12 slide between the first supporting portion 134 and the second supporting portion 135 , so that the fixing member 12 switches between the locked state and the unlocked state.

[0125] See also Figure 5 , Figure 6 , Figure 7 and Figure 8 In one embodiment, the fixing mechanism 100 further includes a pushing component 16, which is movably connected to the sliding member 13 and the housing 11. When the sliding member 13 slides along the first direction X, part of the fixing member 12 can switch from being connected to the first supporting portion 134 to being connected to the second supporting portion 135, and the sliding member 13 can drive the pushing component 16 to move, thereby causing the pushing component 16 to push the expansion card 22 to move in the opposite direction of the first direction X. For example, in one embodiment, when the sliding member 13 slides along the first direction X, the mounting portion 122 of the fixing member 12 can switch from being connected to the first supporting portion 134 to being connected to the second supporting portion 135.

[0126] The sliding member 13 slides in the unlocking direction of the fixing member 12, that is, when the sliding member 13 slides in the first direction X, the fixing member 12 can be converted into a state of unlocking the expansion card 22, that is, the expansion card 22 can be taken out of the housing 11. At the same time, the sliding member 13 also drives the pushing component 16 to move, so that the pushing component 16 pushes the expansion card 22 in the opposite direction of the first direction X, thereby making one end of the expansion card 22 first exposed outside the housing 11, which is conducive to taking the entire expansion card 22 out of the housing 11.

[0127] Continue reading Figure 5 , Figure 6 , Figure 7 and Figure 8 In one embodiment, the pushing assembly 16 includes a first connecting rod 161, a second connecting rod 162 and a pushing portion 163. One end of the first connecting rod 161 is hinged to one end of the second connecting rod 162. The other end of the first connecting rod 161 is rotatably connected to the sliding member 13 and can slide relative to the sliding member 13 along the second direction Y or the opposite direction of the second direction Y. The second direction Y is perpendicular to the first direction X. The other end of the second connecting rod 162 is rotatably connected to the pushing portion 163, and the pushing portion 163 is slidably disposed on the housing 11. The pushing portion 163 can slide along the first direction X or the opposite direction of the first direction X. The pushing portion 163 is used to push the expansion card 22 to make the expansion card 22 slide in the opposite direction of the first direction X. Figure 2As shown, the expansion card 22 is provided with a protrusion 222, which protrudes from the outer wall of the expansion card 22. When the fixing member 12 unlocks the expansion card 22, that is, when the fixing member 12 is disengaged from the first limiting portion 221, the pushing portion 163 can push against the protrusion 222 to push the expansion card 22 out of the shell 11, so as to facilitate the removal of the expansion card 22 from the shell 11.

[0128] When the sliding member 13 slides along the first direction X, one end of the first connecting rod 161 slides along the second direction Y or the opposite direction of the second direction Y relative to the sliding member 13, and the first connecting rod 161 rotates relative to the sliding member 13, thereby causing the second connecting rod 162 to rotate relative to the first connecting rod 161, and the second connecting rod 162 drives the pushing portion 163 to slide in the opposite direction of the first direction X, so that the pushing portion 163 can push the expansion card 22 out of the shell 11, so as to facilitate the separation of the expansion card 22 from the shell 11.

[0129] Continue reading Figure 5 , Figure 6 , Figure 7 and Figure 8 For example, in one embodiment, the sliding member 13 is provided with a long hole, the length direction of the long hole is consistent with the second direction Y, the first connecting rod 161 is connected to the third rotating shaft 164, and the third rotating shaft 164 is arranged in the long hole. During the sliding process of the sliding member 13, the third rotating shaft 164 can slide and rotate in the long hole, thereby pushing the component 16 to rotate relative to the housing 11. The first outer wall 111 of the housing 11 is also provided with a long hole, the length direction of the long hole is consistent with the first direction X, and the pushing portion 163 is arranged in the long hole of the first outer wall 111 of the housing 11, and can slide in the long hole of the first outer wall 111 of the housing 11 along the first direction X or the opposite direction of the first direction X.

[0130] When the sliding member 13 slides along the first direction X, the third rotating shaft 164 slides in the corresponding long hole in the opposite direction of the second direction Y. The movement of the third rotating shaft 164 causes the first connecting rod 161 to rotate relative to the sliding member 13, thereby causing the second connecting rod 162 to rotate relative to the first connecting rod 161, and the second connecting rod 162 drives the pushing portion 163 to slide in the opposite direction of the first direction X, so that the pushing portion 163 can push the expansion card 22 out of the shell 11.

[0131] When the expansion card 22 is withdrawn from the housing 11, the operating portion 152 is toggled to make the rotating portion 151 rotate along the third direction Z, so that the sliding member 13 moves in the opposite direction of the first direction X. At the same time, the mounting portion 122 of the fixing member 12 slides from the position of the first supporting portion 134 away from the second outer wall 112 to the second supporting portion 135, that is, the fixing member 12 slides in the second direction Y, so that the second limiting portion 123 is away from the first limiting portion 221 and the limiting of the expansion card 22 is released. In addition, the sliding member 13 drives the first connecting rod 161 to move, and the first connecting rod 161 drives the second connecting rod 162 and the pushing portion 163 to move, so that the pushing portion 163 moves in the opposite direction of the first direction X, thereby pushing one end of the expansion card 22 out of the housing 11.

[0132] Before the expansion card 22 is inserted into the housing 11, the mounting portion 122 is located at a position where the first support portion 134 is away from the second outer wall 112. During the process of inserting the expansion card 22 into the housing 11, the end a of the expansion card 22 that first enters the housing 11 first contacts the guide slope of the guide block 1231, so that the guide block 1231 of the second position-limiting portion 123 can be pushed by the end a of the expansion card 22, so that the second position-limiting portion 123 slides in the second direction Y and slides to a position where the first support portion 134 is close to the second outer wall 112. This makes it impossible for the first position-limiting portion 221 to block the expansion card 22 from entering the housing 11. When the first limiting portion 221 of the expansion card 22 slides to a position corresponding to the second limiting portion 123, the guiding slope of the second limiting portion 123 is no longer pushed by the expansion card 22, and the second limiting portion 123 slides in the opposite direction of the second direction Y under the pulling force of the elastic reset member 14, and moves again to a position where the first support portion 134 is away from the second outer wall 112, so that the first limiting portion 221 and the second limiting portion 123 form a limiting fit.

[0133] In this solution, the fixing member 12 can be switched between a state of locking the expansion card 22 and a state of unlocking the expansion card 22 simply by driving the sliding member 13 to move, without the need for other tools, thereby facilitating the installation of the expansion card 22 on the fixing mechanism 100, thereby improving the convenience of installing the expansion card 22 on the server 200.

[0134] In addition, those skilled in the art may also make other changes in the present application. Of course, these changes made based on the present application should be included in the scope disclosed in the present application.
