[0002] With the continuous development of network technology, the requirements for servers are also increasing. Function cards used to implement various functions are an important part of servers. For example, high-speed expansion cards (PCI-Express SolidState Drives, or PCIE for short) play a vital role in server network data transmission. However, the installation and removal of high-speed expansion cards and other function cards are cumbersome, and the replacement efficiency of function cards is low. Summary of the Invention

[0006] The fixing device includes a main body and a connector connected to each other. The main body is movably disposed on the base plate. The main body can be fixed or detached from the fixing device by the connector.

[0007] When the connector is in the first state, the main body is fixed to the fixing member through the connector, and the main body abuts against the surface of the function card away from the substrate to fix the function card; when the connector is in the second state, the main body is detached from the fixing member to detach from the function card.

[0008] By adopting the above technical solution, when installing function cards such as high-speed expansion cards, the function card is placed on the surface of the substrate. Then, the connector is adjusted so that it is in a first state, with the main body abutting against the surface of the function card facing away from the substrate. The function card is secured by the cooperation between the main body and the substrate. When it is necessary to remove the function card, the connector is adjusted so that it is in a second state, allowing the main body to detach from the fixing component and thus detach from the function card. This enables the function card to be removed from between the main body and the substrate, simplifying the function card installation and removal process and improving its efficiency.

[0013] In some possible implementations, the connector is provided with a movable slider, and the main body is correspondingly provided with a slot;

[0014] When the slider is positioned in the slot, the connector is in the second state and is relatively fixed to the main body; when the slider disengages from the slot, the first elastic member drives the connector to move along the first direction so that the connector is in the first state.

[0015] In some possible implementations, the connector is provided with a sliding groove for receiving the slider, the sliding groove extending along a second direction perpendicular to the first direction;

[0016] The sliding groove is further provided with a second elastic element. The first end of the second elastic element is connected to the main body, and the second end of the second elastic element is connected to the slider. The second end of the second elastic element can extend and retract along the second direction.

[0038] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0039] As described in the background section, function cards used to implement various functions are an important component of servers. Among them, high-speed expansion cards play a crucial role in server network data transmission. Furthermore, high-speed expansion cards need to be frequently replaced during daily server use to ensure data storage and transmission. However, common high-speed expansion cards typically require multiple screws and other fasteners to be mounted to the baseboard. Replacing a high-speed expansion card necessitates removing and installing these screws, making the process cumbersome and inefficient.

[0040] To address the aforementioned technical problems, this application provides a quick-release fixing structure and server, including a substrate and a fixing device. When installing a high-speed expansion card or other function card, the function card is placed on the surface of the substrate. Then, the connector is adjusted so that it is in a first state, with the main body abutting against the surface of the function card facing away from the substrate, thereby fixing the function card through the cooperation of the main body and the substrate. When it is necessary to remove the function card, the connector is adjusted so that it is in a second state, and the main body detaches from the fixing device to disengage from the function card. This allows the function card to be removed from between the main body and the substrate, simplifying the function card installation and removal process and improving its efficiency.

[0041] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0042] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0043] Reference Figures 1-5 This application provides a quick-release fixing structure for fixing a high-speed expansion card or other function card 400. The quick-release fixing structure includes a base plate 100 and a fixing device. The base plate 100 is used to abut against the surface of the function card 400, and the base plate 100 is provided with a fixing member 110. The fixing device includes a main body 200 and a connector 300 connected to each other. The main body 200 is movably disposed on the base plate 100. The main body 200 can be fixed or detached from the fixing member 110 by the connector 300, so that the function card 400 can be installed or removed through the cooperation between the main body 200 and the base plate 100.

[0044] When the connector 300 is in the first state, the main body 200 is fixed to the fixing member 110 through the connector 300, and the main body 200 abuts against the surface of the function card 400 away from the substrate 100, so that the function card 400 is fixed by the cooperation between the main body 200 and the substrate 100; when the connector 300 is in the second state, the main body 200 is disengaged from the fixing member 110 to disengage from the function card 400, so that the function card 400 can be removed from between the main body 200 and the substrate 100, realizing the disassembly process of the function card 400.

[0045] Reference Figure 2 In some possible implementations, the fixing member 110 passes through the through hole of the function card 400, and the fixing member 110 includes a fixing head 111 and a connecting post 112 connected to each other. The fixing head 111 is fixed to the substrate 100 through the connecting post 112; and / or, the substrate 100 is also provided with at least one connecting part 120 for connecting the function card 400, so that the connecting part 120 and the fixing member 110 can play a certain positioning role for the function card 400, so that the position of the function card 400 is more accurate.

[0046] The fixing head 111 and the connecting post 112 can be arranged along the thickness direction of the function card 400, and the connecting post 112 can extend along the thickness direction of the function card 400. The shape of the fixing head 111 can be set as a square, spherical, hemispherical, etc., and this application embodiment does not further limit it.

[0047] Reference Figures 1-4 Correspondingly, the connector 300 is provided with an installation groove 310 and a fixing groove 320, with the fixing groove 320 connected to the installation groove 310. When the connector 300 is in the first state, the fixing groove 320 accommodates the connecting post 112, and the surface of the connector 300 away from the substrate 100 abuts against the fixing head 111, thereby fixing the connector 300 to a certain extent through the fixing head 111, so that the connector 300 can drive the main body 200 to abut against the surface of the function card 400 away from the substrate 100. When the connector 300 is in the second state, the installation groove 310 accommodates the connecting post 112, and the connector 300 can disengage from the fixing head 111 through the installation groove 310, thereby allowing the main body 200 to disengage from the surface of the function card 400 away from the substrate 100, thus realizing the disassembly process of the function card 400.

[0048] For example, the fixing groove 320 is disposed at the first end of the mounting groove 310 along the first direction, and the connector 300 is slidably disposed on the main body 200 along the first direction, so that the first state and the second state of the connector 300 can be switched by pulling the connector 300 along the first direction; when the function card 400 needs to be fixed, the connector 300 is pulled along the first direction, so that the fixing groove 320 accommodates the connecting post 112, and the surface of the connector 300 away from the substrate 100 abuts against the fixing head 111; when the function card 400 needs to be removed, the connector 300 is pulled in the opposite direction along the first direction, so that the connecting post 112 can move from the fixing groove 320 into the mounting groove 310, so that the main body 200 can detach from the surface of the function card 400 away from the substrate 100.

[0049] Reference Figure 3 and Figure 4 In some possible implementations, the connector 300 is configured as a square plate connector 300, which extends along a first direction; the main body 200 can be configured as a square plate, and the main body 200 can extend along the first direction. The width direction of the main body 200 can be configured as a second direction. The main body 200 is also provided with a receiving cavity 210 extending along the first direction. The receiving cavity 210 accommodates the square plate connector 300 so that the square plate connector 300 can slide along the first direction within the receiving cavity 210. This allows the receiving cavity 210 to play a certain limiting role in the sliding process of the square plate connector 300, thereby ensuring the stability of the square plate connector 300 sliding along the first direction within the main body 200.

[0050] Furthermore, the main body 200 is also provided with a clearance opening 230, which is provided on the surface of the main body 200 facing the substrate 100. The clearance opening 230 is correspondingly provided in the mounting groove 310 and the fixing groove 320, so that the fastener 110 can pass through the clearance opening 230 and enter the mounting groove 310 and the fixing groove 320, thereby reducing the impact of the main body 200 on the movement of the fastener 110.

[0051] It is easy to understand that on the surface of the main body 200, the clearance opening 230 can extend from the surface of the main body 200 toward the substrate 100 to the surface of the main body 200 away from the substrate 100, that is, the clearance opening 230 penetrates through the thickness direction of the main body 200, so that the relative positions of the fastener 110, the mounting groove 310 and the fixing groove 320 can be observed through the clearance opening 230, so as to make the adjustment process of the position of the connector 300 more convenient.

[0052] For example, the main body 200 is also provided with a first elastic member 211. The first end of the first elastic member 211 is connected to the main body 200, and the second end of the first elastic member 211 can extend and retract along a first direction. The second end of the first elastic member 211 is connected to the connector 300. When the connector 300 is in the first state, the first elastic member 211 drives the connector 300 to abut against the connecting post 112, thereby driving the connector 300 through the first elastic member 211, so that the cooperation between the fixing groove 320 and the connecting post 112 is more stable.

[0053] The first elastic member 211 is disposed at one end of the receiving cavity 210 away from the opening. The first elastic member 211 is in a compressed state to push the connector 300 toward the opening. In addition, the fixing groove 320 is disposed on one side of the mounting groove 310 away from the opening. The main body 200 is also provided with a limiting member 220, which is used to abut against the end of the connector 300 away from the first elastic member 211 to reduce the possibility of the connector 300 detaching from the main body 200 through the opening.

[0054] The limiting member 220 can be set as a square limiting member 220, or the limiting member 220 can also be set as a long strip limiting member 220. For example, when the limiting member 220 is set as a long strip limiting member 220, the long strip limiting member 220 can be set at the opening, and the long strip limiting member 220 can extend along the second direction so as to play a certain blocking role on the connecting member 300 through the long strip limiting member 220.

[0055] By adopting the above technical solution, when the main body 200 and the substrate 100 cooperate to fix the function card 400, the connector 300 is in the first state, the fixing groove 320 accommodates the connecting post 112, and the surface of the connector 300 away from the substrate 100 abuts against the fixing head 111; and the first elastic member 211 is in a compressed state, so that the first elastic member 211 provides a thrust to the connector 300, so that the groove wall of the fixing groove 320 away from the opening abuts against the connecting post 112, thereby reducing the possibility of the connecting post 112 detaching from the fixing groove 320.

[0056] For example, the connector 300 is further provided with a push block 340. In the first direction, the push block 340 is disposed at the end of the connector 300 opposite to the first elastic member 211, and the push block 340 is disposed on the surface of the connector 300 opposite to the substrate 100, so that the connector 300 can be driven to slide in the receiving cavity 210 along the first direction by the push block 340, thereby making the movement of the connector 300 more convenient. Furthermore, the push block 340 can be fixed to the connector 300 by adhesive or screws, or the push block 340 can be integrally disposed on the connector 300 to make the connection between the push block 340 and the connector 300 more stable.

[0057] Reference Figures 1-5 In some possible implementations, the connector 300 is further provided with a movable slider 331, and the main body 200 is correspondingly provided with a slot 240, which is used in conjunction with the slider 331. When the slider 331 is placed in the slot 240, the connector 300 is in the second state, and the connector 300 is relatively fixed to the main body 200, so that the connector 300 can be disengaged from the fixing head 111 through the mounting groove 310. When the slider 331 is disengaged from the slot 240, the first elastic member 211 drives the connector 300 to move along the first direction, so that the connecting post 112 enters the fixing groove 320, so that the connector 300 is in the first state.

[0058] It is easy to understand that by providing a first elastic element 211 in the main body 200, the first elastic element 211 can push the connector 300 to move toward the opening, so that when the connector 300 is in the first state, the fit between the connecting post 112 and the fixing groove 320 is more stable; when the connector 300 is in the second state, the first elastic element 211 can push the connector 300 to move toward the opening, so that the connecting post 112 can easily move from the mounting groove 310 along the first direction into the fixing groove 320, thereby affecting the maintenance of the second state of the connector 300.

[0059] A movable slider 331 is provided in the connector 300. When the connector 300 is in the second state, the slider 331 is set in the slot 240, and the connector 300 is relatively fixed to the main body 200, so that the connecting post 112 will not move from the mounting slot 310 along the first direction into the fixing slot 320, so as to ensure the stability of the connector 300 when it is in the second state.

[0060] For example, the connector 300 is provided with a sliding groove 330 for accommodating the slider 331, and the sliding groove 330 extends along the second direction; a second elastic member 332 is also provided in the sliding groove 330, the first end of the second elastic member 332 is connected to the main body 200, the second end of the second elastic member 332 is connected to the slider 331, and the second end of the second elastic member 332 can extend and retract along the second direction, thereby driving the slider 331 to move along the second direction in the sliding groove 330.

[0061] By adopting the above technical solution, when the function card 400 needs to be removed, the connector 300 is in the second state, the slider 331 is set in the card slot 240, and the connector 300 is relatively fixed to the main body 200, so that the connecting post 112 will not move from the mounting slot 310 to the fixing slot 320 in the first direction; when installing a high-speed expansion card or other function card 400, the slider 331 is moved so that the slider 331 is disengaged from the card slot 240, so that the first elastic member 211 can push the connector 300 to move toward the opening, so that the connecting post 112 moves from the mounting slot 310 to the fixing slot 320 in the first direction, thereby realizing the conversion process of the connector 300 from the second state to the first state.

[0062] It should be noted that the slot 240 can face the first direction. When the slider 331 is disposed in the slot 240, the slider 331 abuts against the surface of the slot 240 facing the first elastic member 211. Furthermore, when the slider 331 is moved to disengage from the slot 240, the slider 331 can move along the first direction within the sliding groove 330 to disengage from the slot 240; alternatively, the main body 200 can be configured as an elastic body 200 so that the slider 331 can drive the elastic body 200 to deform, thereby disengaging the slider 331 from the slot 240. This application embodiment does not impose further limitations in this regard.

[0063] In some possible implementations, the body 200 can be connected to the substrate 100 in a variety of ways so that the body 200 can abut against or detach from the surface of the function card 400 away from the substrate 100.

[0064] Reference Figures 5-8For example, the main body 200 is provided with a rotating shaft 250, and the main body 200 is rotatably disposed on the substrate 100 via the rotating shaft 250; the rotating shaft 250 can extend along a first direction, and the rotating shaft 250 is disposed at the edge of the main body 200 along a second direction; when installing a function card 400 such as a high-speed expansion card, the slider 331 is first moved so that the main body 200, disposed in the card slot 240, rotates around the rotating shaft 250, so that the surface of the main body 200 facing the substrate 100 abuts against the function card 400 away from the surface of the substrate 100; when it is necessary to remove the function card 400, the connector 300 is moved along the first direction so that the connector 112 can move from the fixing slot 320 to the mounting slot 310, and then the slider 331 is moved so that the main body 200, disposed in the card slot 240, rotates around the rotating shaft 250, so that the surface of the main body 200 facing the substrate 100 moves away from the surface of the function card 400 away from the surface of the substrate 100, thereby realizing the removal process of the function card 400.

[0065] The main body 200 is also provided with at least one third elastic member 251. The end of the third elastic member 251 facing away from the main body 200 is connected to the substrate 100. The third elastic member 251 is used to drive the main body 200 to rotate toward the substrate 100, thereby making it more convenient for the surface of the main body 200 facing the substrate 100 to abut against the surface of the function card 400 facing away from the substrate 100.

[0066] For example, the third elastic element 251 can be a torsion spring, and the number of the third elastic elements 251 can be two. The two third elastic elements 251 can be arranged along the first direction on the rotation shaft 250, so that the main body 200 can be driven to rotate around the rotation shaft 250 by the two third elastic elements 251.

[0067] Reference Figures 1-6 In some possible implementations, the substrate 100 is provided with two positioning members 130, which are arranged along a first direction and a main body 200 is accommodated between the two positioning members 130. The positioning members 130 are used to pass through the rotating shaft 250, so that the rotating shaft 250 can pass through the two positioning members 130 and the main body 200, thereby realizing the rotation process of the main body 200 around the rotating shaft 250. In addition, the two positioning members 130 can play a certain positioning role in the installation process of the main body 200, thereby making the installation process of the main body 200 more convenient.

[0068] For example, when multiple function cards 400 need to be installed, multiple fasteners 110 can be provided on the substrate 100, and the multiple fasteners 110 are arranged along the first direction, so that multiple main bodies 200 can be connected by one substrate 100, and thus the installation process of multiple function cards 400 can be realized by one substrate 100.

[0069] In summary, when installing a high-speed expansion card or other function card 400, the slider 331 is first moved to disengage from the card slot 240, so that the main body 200 abuts against the surface of the substrate 100 while the function card 400 is away from the surface of the substrate 100; the first elastic member 211 drives the connector 300 to move along the first direction, so that the connecting post 112 enters the fixing groove 320, so that the connector 300 is in the first state, thereby enabling the function card 400 to be fixed through the cooperation of the main body 200 and the substrate 100.

[0070] When the function card 400 needs to be removed, the connector 300 is moved in the reverse direction, so that the connecting post 112 can move from the fixing groove 320 to the mounting groove 310. Then, the slider 331 is moved, so that the main body 200, which is set in the card slot 240, rotates around the rotating shaft 250, so that the surface of the main body 200 facing the substrate 100 moves away from the function card 400 and away from the surface of the substrate 100, so that the connector 300 is in the second state, thereby enabling the function card 400 to be removed from between the main body 200 and the substrate 100, realizing the disassembly process of the function card 400. Compared with the related technology, which requires the removal and installation of multiple screws to realize the disassembly and assembly process of the high-speed expansion card, the quick-release fixing structure provided in this application embodiment can simplify the disassembly and assembly process of the function card 400 and improve the disassembly and assembly efficiency of the function card 400.

[0071] This application also provides a server, including a function card and the aforementioned quick-release fixing structure.

[0072] Since the server includes the aforementioned quick-release fixing structure, the advantages of this server including the aforementioned quick-release fixing structure can be specifically referred to in the relevant description above, and will not be repeated here.
