Technical Field

[0001] The present application relates to the technical field of electronic devices, and in particular to a computing device. Background Art

[0002] A computing device is provided with a plurality of boards, which can be fixedly mounted on a circuit board. In the prior art, the installation of the boards is relatively complicated and requires the use of installation tools, which makes the installation of the boards relatively inconvenient. Summary of the Invention

[0003] The purpose of this application is to provide a computing device for facilitating the installation of a board.

[0004] In order to achieve the above objectives, this application provides the following technical solutions:

[0005] An embodiment of the present application provides a computing device, comprising: a chassis, a circuit board, a card, a first fixing structure, a second fixing structure, a first mounting assembly, and a second mounting assembly. The first fixing structure and the second fixing structure are spaced apart and both are fixed within the chassis; the first fixing structure is provided with a first connecting portion, and the second fixing structure is provided with a positioning post. The circuit board is fixed within the chassis, and a card mounting position is defined between the circuit board, the first fixing structure, and the second fixing structure. The card is mounted in the card mounting position and electrically connected to the circuit board; the card includes opposing first and second ends. The first mounting assembly includes a first connecting frame and a movable pin; the first connecting frame is fixedly connected to the first end of the card; the movable pin is fixed to the first connecting frame and connected to the first connecting portion to constrain the first end of the card. The second mounting assembly includes a second connecting frame; the second connecting frame is fixedly connected to the second end of the card; the second connecting frame is provided with a first limiting hole, and the positioning post is located in the first limiting hole to constrain the second end of the card.

[0006] In the above-mentioned computing device, the first fixed structure and the second fixed structure can be fixedly connected to the chassis. A board installation position can be defined between the first fixed structure, the second fixed structure and the circuit board. When the board is installed in the board installation position, the first end of the board is adjacent to the first fixed structure, and the second end of the board is adjacent to the second fixed structure. The first connecting frame of the first mounting assembly can be fixedly connected to the first end of the board, and the movable pin can be fixed to the first connecting frame and connected to the first connecting portion, so that the movable pin can fix the first connecting frame to the first fixed structure, and the first connecting frame can be fixedly connected to the first end of the board, so that the first end of the board can be fixed to the first fixed structure through the first connecting frame. The positioning column provided on the second fixed structure can pass through the first limiting hole of the second connecting frame, so that the positioning column can limit the second connecting frame, thereby preventing the board from shaking, so that the board can be installed without using installation tools, thereby speeding up the installation of the board.

[0007] In some embodiments, the first connecting frame includes a first plate, a second plate, and a third plate. The first plate is connected to the first end of the second plate, and the third plate is connected to the second end of the second plate. The first, second, and third plates enclose an installation space for accommodating the first fixing structure. The first plate is fixedly connected to the first end of the board; a movable pin is fixed to the third plate. When the first fixing structure is located in the installation space, the movable pin can connect with the first connecting portion to restrain the first end of the board.

[0008] Among them, the first plate is fixedly connected to the first end of the board, and the third plate can be fixedly connected to the movable pin, thereby fixedly connected to the first fixed structure through the movable pin. The second plate can connect the first plate and the third plate, so that the first connecting frame can be fixedly connected to the first end of the board and the first fixed structure.

[0009] In some embodiments, the first fixing structure includes a limiting recess, and the first plate includes a mounting rib, and the mounting rib is located in the limiting recess.

[0010] With such a configuration, the limiting recess can limit the installation edge, thereby preventing the first connecting frame from shaking and facilitating the fixation of the first connecting frame.

[0011] In some embodiments, the movable pin comprises a spring pin; the spring pin comprises a second fixing member, a third elastic member, and a third movable member; the second fixing member is fixedly connected to the first connecting frame; the third movable member is connected to the second fixing member via the third elastic member, and the third movable member and the second fixing member are slidably engaged. The third movable member passes through the first connecting portion under the elastic force of the third elastic member.

[0012] The elastic force of the third elastic member causes the third movable member to change position, allowing it to pass through the first connecting portion and securely connect to the first connecting portion, thereby securing the first connecting frame to the first fixing structure. The spring pin secures the first connecting frame to the first fixing structure without the need for tools, making it easier for users to attach the first end of the board to the first fixing structure. Furthermore, this speeds up board removal.

[0013] In some embodiments, the second mounting assembly further includes: an elastic locking assembly; the elastic locking assembly is mounted on the second fixing structure; the elastic locking assembly is used to engage with the positioning column under the action of elastic force.

[0014] The elastic locking assembly engages with the positioning post to prevent the second connecting frame from disengaging from the post, thereby preventing the board and the second connecting frame connected to the board from falling off the second fixing structure. This further strengthens the connection between the board and the second connecting frame connected to the second fixing structure. Furthermore, the elastic locking assembly secures the second connecting frame to the second fixing structure under the action of elastic force, thereby simplifying the board installation process.

[0015] In some embodiments, the elastic locking assembly includes a first fixed member, a first movable member, a second movable member, and a first elastic member. The first fixed member is fixed to the second fixed structure. The first movable member is movably connected to the first fixed member. The first movable member is provided with a second limiting hole for allowing the positioning post to pass through, so that the first movable member is positioned on the surface of the second connecting frame facing away from the second fixed structure. The second movable member is provided with a locking hole, which includes a locking area and a passing area, the locking area communicating with the passing area. The positioning post includes a column and a locking head. One end of the column is fixedly connected to the second fixed structure, and the other end of the column is fixedly connected to the locking head. The radial dimension of the locking head is larger than that of the column. The passing area is for allowing the locking head and the column to pass through. The locking area is for allowing the column to pass through and for restricting the locking head from passing through. The second movable member is elastically connected to the first movable member via the first elastic member, which abuts the second movable member to confine the column to the locking area.

[0016] The first elastic member provides elastic force for the elastic locking assembly. When installing the board, the first elastic member can be compressed. For example, the elastic force can be directed from the locking area to the pass-through area. Under the action of this elastic force, the positioning post can be fixed to the locking area of ​​the second movable member, thereby locking the second movable member. At this time, the second movable member presses against the first movable member, locking the first movable member. The first movable member can then secure the second connecting frame and the board, achieving tool-free installation of the board.

[0017] Furthermore, when removing the board, the relative positional relationship between the second movable member and the positioning post can be changed, allowing the fixed post to enter the passage zone. When the fixed post enters the passage zone from the locking zone, the positioning post is no longer able to restrain the second movable member, and consequently, the second movable member is no longer able to restrain the first movable member. At this point, the first movable member can be moved away from the second connecting frame, so that the first movable member no longer presses against the second connecting frame, allowing the user to remove the second connecting frame and the second end of the board. This enables tool-free removal of the second end of the board.

[0018] In some embodiments, the first elastic member includes a compression spring or a tension spring, wherein the compression spring and the tension spring have lower costs.

[0019] In some embodiments, the first fixed member includes a first rotation hole, the first movable member includes a second rotation hole, and a rotation shaft is disposed in the first rotation hole and the second rotation hole so that the first movable member can rotate relative to the first fixed member.

[0020] The rotating shaft can be set in the first rotating hole and the second rotating hole, so that the first movable part can be rotatably connected to the first fixed part via the rotating shaft. When the user installs the board, the first movable part can be rotated so that the first movable part presses on the second connecting frame. When the user disassembles the board, the user can rotate the first movable part so that the first movable part moves away from the second connecting frame and no longer presses on the second connecting frame, thereby disassembling the second connecting frame and the board. By making the first movable part rotatably connected to the first fixed part via the rotating shaft, it is convenient for the user to operate the first movable part so that the first movable part presses on the second connecting frame, or moves the first movable part away from the second connecting frame and no longer presses on the second connecting frame.

[0021] In addition, the first movable member can be rotatably connected to the first fixed member via the rotating shaft, thereby preventing the first movable member from falling off the second fixed structure.

[0022] In some embodiments, the elastic locking assembly further includes a second elastic member. When the column is located in the passing area, under the elastic force of the second elastic member, the locking hole and the second limiting hole are both separated from the positioning column.

[0023] When the main body of the positioning post is located in the pass-through zone, the positioning post cannot limit the second movable member. At the same time, under the elastic force of the second elastic member, the locking hole and the second limiting hole can be separated from the positioning post, thereby causing the second movable member and the first movable member to be separated from the positioning post, so that the first movable member no longer presses on the second connecting frame, and the first movable member can no longer fix the second connecting frame, allowing the user to remove the second end of the board. Therefore, by providing the second connecting frame, when the positioning post is located in the pass-through zone, the first movable member can automatically move away from the second connecting frame, thereby achieving automatic unlocking of the elastic locking assembly and accelerating the removal of the board.

[0024] In some embodiments, the second elastic member comprises a torsion spring.

[0025] The torsion spring may include a first connecting end and a second connecting end, wherein the first connecting end and the second connecting end are connected to the first movable member and the second fixed structure respectively.

[0026] In some embodiments, the elastic locking assembly further comprises a limiting post fixed to the first movable member. The second movable member is provided with a limiting slot slidably connected to the limiting post to limit the sliding direction of the second movable member relative to the first movable member.

[0027] The limiting post is located in the limiting sliding groove and can slide along the limiting sliding groove, so that the user can conveniently control the moving direction of the second movable member.

[0028] In some examples, the limiting sliding groove extends along the second direction.

[0029] When removing the board, the second movable member needs to be moved in the direction from which the second movable member points to the first elastic member, wherein the direction from which the second movable member points to the first elastic member is parallel to the second direction. Therefore, by extending the limiting slide groove along the second direction, it is easier for the user to push the second movable member in the direction from which the second movable member points to the first elastic member, thereby preventing the second movable member from deviating from the second direction.

[0030] In some embodiments, the limiting column includes a limiting flange extending along the radial direction of the limiting column, and the limiting flange is used to limit the limiting sliding groove from separating from the limiting column.

[0031] Among them, by arranging a limiting flange on the limiting column, the limiting slide groove can be limited from separating from the positioning column, that is, the second movable part can be limited from separating from the limiting column, thereby improving the reliability of the connection between the second movable part and the first movable part.

[0032] In some embodiments, the elastic locking assembly further includes an operating portion, the operating portion including an operating surface and an indicator mark. The operating surface intersects the second direction. The indicator mark is used to indicate the pressing direction of the second movable member, so that after the second movable member is pressed by the operating surface, the column is positioned in the pass-through area.

[0033] The user can apply a force to the operating surface in a direction from the passing area to the locking area, thereby causing the positioning post to enter the passing area. The direction from the passing area to the locking area is parallel to the second direction, and the operating surface intersects the second direction. Therefore, it is convenient to apply a force to the second movable member in a direction from the passing area to the locking area.

[0034] In addition, by providing an indicator mark to indicate the pressing direction of the second movable member, it is convenient for the user to apply pressure to the second movable member, thereby causing the second movable member to move in the direction from the locking area to the passing area.

[0035] In some embodiments, any of the boards includes a GPU board or a PCIE board. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in some embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, not all embodiments. Based on the embodiments provided in this application, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of this application.

[0052] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to".

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of this application, unless otherwise specified, "plurality" means two or more.

[0054] When describing some embodiments, the word "connected" and its derivatives may be used. The term "connected" should be understood broadly. For example, "connected" can mean fixed, removable, or integrated; it can be directly connected or indirectly connected through an intermediary. The embodiments disclosed herein are not necessarily limited to the contents of this document.

[0057] Figure 1Ais a block diagram of a computing device 1000 according to some embodiments.

[0058] See also Figure 1A Some embodiments of the present application provide a computing device 1000. For example, the computing device 1000 may be a server (such as a tower server, a rack server, and a blade server), a computer host, or other device with computing and processing capabilities.

[0059] The computing device 1000 can be roughly rectangular. To facilitate the description of the various embodiments below, an XYZ coordinate system is established. Specifically, the width direction of the computing device 1000 is defined as the X-axis direction, the length direction of the computing device 1000 is defined as the Y-axis direction, and the height direction of the computing device 1000 is defined as the Z-axis direction. It is understood that the coordinate system setting of the computing device 1000 can be flexibly set according to actual needs and is not specifically limited here.

[0060] like Figure 1A As shown, the computing device 1000 may include a chassis 10 , wherein the chassis 10 may have a receiving space.

[0061] For example, the chassis 10 may include a main body 11 and a cover 12, which are coupled to each other to enclose the aforementioned accommodation space. The connection between the main body 11 and the cover 12 may be detachable, such as by snapping, so that the cover 12 can be opened quickly and easily without tools to expose the various components within the main body 11.

[0062] Figure 1B for Figure 1A The internal structure diagram of the computing device 1000, wherein Figure 1B In the illustrated embodiment, only a partial structure of the computing device 1000 is shown.

[0063] like Figure 1B As shown, the computing device 1000 may further include a circuit board 20, a first fixing structure 101 and a second fixing structure 102. The circuit board 20, the first fixing structure 101 and the second fixing structure 102 may be fixed to the chassis 10 (eg, Figure 1A shown).

[0064] In addition, a central processing unit (CPU), a power supply, a fan and other structures may also be provided in the accommodation space, which are not listed here one by one.

[0065] For example, the box body 11 may include a bottom plate 111 and two side plates 112, the bottom plate 111 includes two opposite edges, and the two side plates 112 are respectively arranged along the two edges of the bottom plate 111. Among them, one end of the two side plates 112 is fixed to the bottom plate 111, and the cover body 12 (such as Figure 1A As shown in FIG. 1 , the chassis 10 is formed by covering the two side panels 112 at one end away from the bottom panel 111 .

[0066] The chassis 10 may further include a power module enclosure 106, which is located between the two side panels 112 and can be connected to one of the side panels 112 and the bottom panel 111. The power module enclosure 106, one of the side panels 112, and the bottom panel 111 can enclose a power module installation position. The power module installation position can be used to install a power module, which can be used to power electronic devices (such as a motherboard, CPU, and fan, etc.) within the chassis 10. The power module enclosure may include a first plate 1061 parallel to the side panels 112 and a second plate 1062 parallel to the bottom panel 111, wherein one end of the first plate 1061 is connected to the bottom panel 111, one end of the second plate 1062 is connected to an end of the first plate 1061 away from the bottom panel 111, and the other end of the second plate 1062 is connected to one of the side panels 112.

[0067] The first fixing structure 101 and the second fixing structure 102 are spaced apart and both are fixed in the chassis 10 .

[0068] The first fixing structure 101 may be fixedly connected to the chassis 10 , or may be fixedly connected to other components in the chassis 10 .

[0069] The second fixing structure 102 can be fixedly connected to the chassis 10 or to other components within the chassis 10. In some examples, the second fixing structure 102 can serve as a rear window of the chassis. In other examples, the second fixing structure 102 can be disposed within the chassis, in which case the second fixing structure 102 can be fixedly connected to the chassis 10 or to other components within the chassis 10.

[0070] In some examples, the first fixing structure 101 and the second fixing structure 102 may be spaced apart along a first direction and both extend along a second direction intersecting the first direction. Figure 1B The Y-axis direction in the second direction can be, for example, Figure 1B The X-axis direction in .

[0071] The circuit board 20 is fixed in the chassis 10 . For example, the circuit board 20 can be mounted on the bottom plate 111 of the chassis 10 .

[0072] A board installation position can be defined between the circuit board 20 , the first fixing structure 101 and the second fixing structure 102 .

[0073] The first fixing structure 101 is fixedly connected to the chassis 10 . At this time, after the first fixing structure 101 is connected to the chassis 10 , no relative movement occurs between the two.

[0074] Figure 1C for Figure 1B Structural diagram of the first fixed structure 101 in FIG.

[0075] like Figure 1C shown, and combined with Figure 1B The first fixing structure 101 is provided with a first fixing lug 1011 at each end in the second direction. The first fixing lug 1011 is provided with a first fixing hole, and the chassis 10 is provided with a second fixing hole. A first fastener can be sequentially passed through the first fixing hole and the second fixing hole to attach the first fixing structure 101 to the chassis 10. The first fastener can be a pin, bolt, screw, or other component. In addition, the first fixing lug 1011 and the chassis 10 can also be connected by welding, clamping, or bonding, etc., which are not listed here.

[0076] For example, both ends of the first fixing structure 101 in the second direction may be connected to the two side plates 112 via the first fixing ear plates 1011 , respectively.

[0077] Figure 1D for Figure 1B Schematic diagram of the second fixed structure 102.

[0078] like Figure 1D shown, and combined with Figure 1B The second fixing structure 102 is fixedly connected to the chassis 10. At this time, after the second fixing structure 102 is connected to the chassis 10, no relative movement occurs between the two.

[0079] For example, the second fixing structure 102 may include a first side and a second side that are opposite to each other, wherein the first side may be fixedly connected to one end of a side panel 112, and the second side may be fixedly connected to the first plate 1061 of the power module enclosure 106. In this case, the second fixing structure 102 is located between the power module enclosure 106 and one of the side panels 112. It should be noted that the side panel to which the second fixing structure 102 is connected is not the same side panel 112 as the side panel 112 to which the power module enclosure 106 is connected.

[0080] The second fixing structure 102 may include a first beam 103, a second beam 104, and a connecting beam 105. The first beam 103 and the second beam 104 may both extend along the second direction. The first beam 103 is located on a side of the second beam 104 away from the circuit board 20. The first beam 103 has two ends connected to a side panel 112 and the first plate 1061 of the power module enclosure 106. The second beam 104 has two ends fixedly connected to a side panel 112 and the first plate 1061 of the power module enclosure 106.

[0081] One end of the connecting beam 105 is connected to the first beam 103, and the other end is connected to the second beam 104. For example, there can be multiple connecting beams 105, and the multiple connecting beams 105 can be spaced apart along the extension direction (i.e., the second direction) of the first beam 103. By providing multiple connecting beams 105 between the first beam 103 and the second beam 104, the second fixed structure 102 can be made more stable.

[0082] Figure 1E for Figure 1A Another structural diagram of the computing device 1000 in FIG.

[0083] like Figure 1E As shown, the computing device 1000 may further include at least one board 30, which may be installed in the chassis 10. The board 30 may be installed in a board installation position and connected to the circuit board 20 (eg, Figure 1B as shown) electrical connections.

[0084] Figure 2 for Figure 1A Another structural diagram of the computing device 1000 in FIG.

[0085] See also Figure 2 For example, the circuit board 20 may have a card slot 201, and the card 30 may be provided with a gold finger connection portion, wherein the gold finger connection portion may be plugged into the card slot 201, thereby electrically connecting the card 30 to the circuit board 20. It is understandable that Figure 1A In this embodiment, the circuit board 20 may have multiple card slots 201. The multiple card slots 201 may all extend along the first direction and be spaced apart along the second direction. Therefore, the space between the first fixing structure 101 and the second fixing structure 102 may have multiple card mounting locations, which are sequentially arranged along the second direction.

[0086] In some examples, circuit board 20 may be a server motherboard.

[0087] In some examples, one or more boards 30 may be installed in the computing device 1000. When multiple boards 30 are installed in the computing device 1000, the multiple boards 30 may be the same or different. For example, any board 30 may be a GPU (Graphics Processing Unit) board or a PCIE (Peripheral Component Interconnect Express) board, etc. It is understandable that the board 30 here may include any electronic device in the computing device 1000 that needs to be plugged into and electrically connected to the circuit board 20 and needs to be fixed and prevented from tipping over. The electronic device may directly constitute the board 30, or the electronic device may also constitute the board 30 as a whole by adding a counterweight. The board 30 here has opposite first ends 301 and second ends 302. For example, the board 30 may extend along a first direction and have opposite first ends 301 and second ends 302 in the first direction.

[0088] In some examples, the computing device 100 may further include a cable management clip 109, wherein the cable management clip 109 may be disposed on a side of the first fixing structure 101 away from the circuit board 20. The cable management clip 109 may organize the cables within the computing device 100, thereby preventing the cables within the computing device 100 from becoming too cluttered. For example, the cable management clip 109 may be threadedly connected to the first fixing structure 101.

[0089] like Figure 2 As shown, the computing device 1000 may further include a first mounting assembly 40 and a second mounting assembly 50. The first mounting assembly 40 and the second mounting assembly 50 may be installed in the chassis 10.

[0090] Figure 3 for Figure 2 A structural diagram of the computing device 1000 from another perspective.

[0091] In some examples, the first fixing structure 101 may include a plurality of heat dissipation openings 107 , which may be sequentially arranged along the second direction. The heat dissipation openings 107 provided on the first fixing structure 101 may dissipate heat from the board 30 .

[0092] In some examples, there may be multiple cable management clips, and the multiple cable management clips may be sequentially arranged along the extension direction of the first fixing interface 101 (ie, the second direction).

[0093] like Figure 3 As shown, the first mounting assembly 40 is used to fix the first end 301 of the board 30 relative to the first fixing structure 101. For example, the first mounting assembly 40 may include a first connecting frame 401 and a movable pin 402.

[0094] The first connecting frame 401 is fixedly connected to the first end 301 of the board 30. This means that after the first connecting frame 401 is connected to the first end 301 of the board 30, no relative displacement occurs between the two. For example, the first connecting frame 401 and the board 30 can be detachably connected, for example, using bolts, screws, or pins.

[0095] In addition, the first connecting frame 401 and the board 30 may also be connected by other means such as clamping, welding, etc., and the connection method between the first connecting frame 401 and the board 30 is not limited here.

[0096] Figure 4A for Figure 3 FIG. 4 is a structural diagram of the first connecting frame 401 and the first end 301 of the board 30.

[0097] like Figure 4A As shown, the first fixing structure 101 (as Figure 3 As shown) is provided with a first connecting portion 1020 (as shown Figure 3 movable pin 402 is fixed to the first connecting frame 401 and connected to the first connecting frame 401 to limit the first end 301 of the board 30.

[0098] For example, the movable pin 402 can restrict the first end 301 of the board 30 from moving within a first reference plane perpendicular to the first direction, wherein the first reference plane perpendicular to the first direction is the XZ plane.

[0099] In some examples, the first connection portion 1020 may include a first connection hole or a first connection slot. In this case, one end of the movable pin 402 may be fixed in the first connection hole or the first connection slot.

[0100] In some examples, the first connecting frame 401 is provided with a second connecting portion 4010. In this case, a movable pin 402 connects the second connecting portion 4010 and the first connecting portion 1020. For example, the second connecting portion 4010 may include a first connecting hole, and the first connecting portion 1020 may include a second connecting hole. In this case, the movable pin 402 may sequentially pass through the first connecting hole and the second connecting hole, thereby securely connecting the first connecting frame 401 to the first fixed structure 101. Alternatively, the second connecting portion 4010 may be a first connecting slot, wherein the opening of the first connecting slot may be located on an edge of the first connecting frame 401. Furthermore, the first connecting slot may extend through the first connecting frame 401 in a first direction, and the first connecting portion 1020 may include a second connecting slot, wherein the opening of the second connecting slot may be located on a surface of the first fixed structure 101 facing the first connecting frame 401. It is understood that the second connecting slot does not extend through the first fixed structure 101. The movable pin can pass through the first connecting groove and connect with the second connecting groove, thereby fixedly connecting the first connecting frame 401 and the first fixing structure 101.

[0101] like Figure 4A As shown, in some examples, the first connecting frame 401 may include a first plate 4011, a second plate 4012, and a third plate 4013. The first plate 4011 is adjacent to the first end of the second plate 4012, and the third plate 4013 is connected to the second end of the second plate 4012. The first plate 4011, the second plate 4012, and the third plate 4013 enclose an installation space. The installation space is used to accommodate the first fixed structure 101 (such as Figure 3 shown).

[0102] The first plate 4011 and the third plate 4013 are spaced apart. Figure 3 As shown in FIG, the third plate 4013 may be located between the first plate 4011 and the third plate 4013. For example, the first plate 4011 and the third plate 4013 may be arranged in parallel.

[0103] The end of the first plate 4011 away from the second plate 4012 and the end of the third plate 4013 away from the second plate 4012 form an opening of the installation space, so the first fixing structure 101 can enter the installation space through the opening.

[0104] The first plate 4011 can be fixedly connected to the first end 301 of the board 30, thereby fixing the first connecting frame 401 to the first end 301. For example, the first end 301 of the board 30 is provided with a third fixing hole 305, and the first plate 4011 is provided with a fourth fixing hole 60. The second fastener can pass through the fourth fixing hole 60 and be installed in the third fixing hole 305, thereby fixing the first connecting frame 401 to the first end 301 of the board 30 via the first plate 4011. For example, the second fastener can be a bolt, a screw, a pin, etc. In addition, the first plate 4011 can also be fixed to the first end 301 of the board 30 by welding, clamping, or gluing.

[0105] In some examples, the first end 301 of the board 30 may be provided with a plurality of third fixing holes 305, and the first plate 4011 may be provided with a plurality of fourth fixing holes 60, wherein the number of fourth fixing holes 60 may be the same as the number of third fixing holes 305. Accordingly, the number of second fasteners may be multiple, with one second fastener being connected to one fourth fixing hole 60 and one third fixing hole 305. For example, the number of third fixing holes 305 and the number of fourth fixing holes 60 may both be three. Of course, in other embodiments, the number of third fixing holes 305 and fourth fixing holes 60 may not be limited to three.

[0106] For example, the plurality of third fixing holes 305 are sequentially arranged along the third direction, and the plurality of fourth fixing holes 60 are sequentially arranged along the third direction, wherein the third direction is perpendicular to the first direction and the second direction.

[0107] By providing multiple third fixing holes 305 and multiple fourth fixing holes 60 , the first plate 4011 and the first end 301 of the board 30 can be connected at multiple points, thereby increasing the connection reliability between the first plate 4011 and the first end 301 of the board 30 .

[0108] In some examples, the dimensions of the plurality of fourth fixing holes 60 in the third direction (i.e., the Z-axis direction) gradually increase. While the design of the fourth fixing holes 60 and the third fixing holes 305 may have errors, gradually increasing the dimensions of the plurality of fourth fixing holes 60 in the Z-axis direction can avoid a situation where, when the errors in the third fixing holes 305 and / or the fourth fixing holes 60 are large, the third fixing holes 305 and the fourth fixing holes 60 are misaligned, thereby preventing some of the third fixing holes 305 and the fourth fixing holes 60 from being connected via the second fastener. Therefore, by gradually increasing the dimensions of the plurality of fourth fixing holes 60 in the Z-axis direction, the plurality of third fixing holes 305 can all be connected to the plurality of fourth fixing holes 60 via the second fastener, thereby ensuring the stability of the connection between the first plate 4011 and the first end 301 of the board 30.

[0109] like Figure 4A As shown, the movable pin 402 can be fixed to the third plate 4013. Figure 3 When the movable pin 402 is located in the installation space, the movable pin 402 can be connected with the first connecting portion 1020 (as shown in FIG. Figure 3 As shown) is connected to limit the first end 301 of the board 30.

[0110] Among them, the first plate 4011 is fixedly connected to the first end 301 of the board 30, and the third plate 4013 can be fixedly connected to the movable pin 402, thereby being fixedly connected to the first fixed structure 101 through the movable pin 402. The second plate 4012 can connect the first plate 4011 and the third plate 4013, so that the first connecting frame 401 can be fixedly connected to the first end 30 of the board 30 and also to the first fixed structure 101.

[0111] For example, the third plate 4013 may be provided with a second connecting portion 4010, and the first fixing structure 101 (such as Figure 3 As shown) is provided with a first connecting portion 1020 (as shown Figure 3 As shown in FIG. 4 , the movable pin 402 can be sequentially connected to the second connection portion 4010 and the first connection portion 1020, thereby fixing the third plate 4013 to the first fixed structure 101, that is, fixing the first connecting frame 401 to the first fixed structure 101. The first connecting frame 401 can also be fixedly connected to the first end 301 of the board 30 via the first plate 4011, thereby fixing the first end 301 of the board 30 to the first fixed structure 101 via the first connecting frame 401. The movable pin 402 is easy to install and remove, making it convenient for users to install the first end 301 of the board 30 to the first fixed structure 101 via the first connecting frame 401, thereby speeding up the installation and removal of the board 30.

[0112] like Figure 4A As shown, in some examples, the movable pin 402 may include a spring pin. The spring pin may include a second fixing member 4021, a third elastic member (not shown), and a third movable member 4022. The second fixing member 4021 is fixedly connected to the first connecting frame 401. The third movable member 4022 is connected to the second fixing member 4021 via the third elastic member, and the third movable member 4022 and the second fixing member 4021 are slidably engaged. The third movable member 4022 passes through the first connecting portion 1020 under the elastic force of the third elastic member.

[0113] Under the elastic force of the third elastic member, the position of the third movable member 4022 can be changed, thereby passing through the second connecting portion 4010 and the first connecting portion 1020 to secure the first connecting frame 401 to the first fixing structure 101. The spring pin secures the first connecting frame 401 to the first fixing structure 101 without the use of tools, making it easier for users to install the first end 301 of the board 30 to the first fixing structure 101 and speeding up the installation of the first end 301 of the board 30. Furthermore, it also speeds up the removal of the first end 301 of the board 30.

[0114] The second fixing member 4021 is fixedly connected to the first connecting frame 401, which means that after the second fixing member 4021 is connected to the first connecting frame 401, the two do not move relative to each other and are relatively fixed. For example, the second fixing member 4021 and the first connecting frame 401 can be fixedly connected by welding, clamping, or threading, etc., which are not listed here.

[0115] One end of the third elastic member can be connected to the third movable member 4022 , and the other end can be connected to the second fixed member 4021 , thereby achieving elastic connection between the third movable member 4022 and the second fixed member 4021 via the third elastic member.

[0116] The third movable member 4022 is slidably matched with the second fixed member 4021, so the relative position between the third movable member 4022 and the second fixed member 4021 can be changed. For example, when the third elastic member is in the first state, the first part of the third movable member 4022 can be made to protrude from the second fixed member 4021. At this time, the first part can pass through the second connecting portion 4010 and the first connecting portion 1020, so that the first plate 4011 is fixedly connected to the first end 301 of the board 30. When the third elastic member is in the second state, the first part of the third movable member 4022 can be partially retracted into the second fixed member 4021. At this time, the length of the part of the third movable member 4022 protruding from the second fixed member 4021 is shorter than the length of the first part. At this time, the first part can be withdrawn from the first connecting portion 1020, and no longer fixes the first plate 4011 and the first end 301 of the board 30. The user can then move the first connecting frame 401 and the first end 301 of the board 30 by the first fixing structure 101 (such as Figure 3 Remove from the mounting plate (as shown).

[0117] For example, the second fixing member 4021 may include a fixed sleeve, a sliding cavity is provided inside the fixed sleeve, and the third elastic member is located in the sliding cavity. The third movable member 4022 may include a pressing cap and a movable column, wherein the pressing cap is located at one end of the fixed sleeve, and the end of the pressing cap close to the fixed sleeve is connected to the movable column, and a portion of the movable column is located inside the fixed sleeve. The end of the third elastic member away from the pressing cap can be connected to the movable column, and the other end can be connected to the fixed sleeve. For example, the third elastic member can be a spring or a compression spring, in which case the movable column can pass through the accommodating space in the middle of the third elastic member.

[0118] At this time, by applying external force to the pressing cap, the movable column can be switched between the first state and the second state, which is convenient for user operation and facilitates the installation and removal of the board 30, thereby achieving rapid installation and removal of the board 30.

[0119] For example, the third elastic member may be a spring or a compression spring.

[0120] like Figure 4A As shown, in some embodiments, the first plate 4011 may include a mounting edge 73. For example, the first plate 4011 may include a first sub-plate 71 and a second sub-plate 72. The second sub-plate 72 and the third plate 4013 are respectively connected to two adjacent edges of the second plate 4012, with a gap provided between the second sub-plate 72 and the third plate 4013. The first fixing structure 101 may be installed between the second sub-plate 72 and the third plate 4013.

[0121] The first sub-board 71 may be used for fixed connection with the first end 301 of the board 30 . For example, the fourth fixing hole 60 may be provided on the first sub-board 71 .

[0122] The side of the second sub-plate 72 away from the first sub-plate 71 can serve as a mounting edge 73 .

[0123] Illustratively, the mounting rib 73 extends along the third direction.

[0124] For example, the first sub-plate 71 and the second sub-plate 72 may both be plate-shaped. For example, the first sub-plate 71 and the second sub-plate 72 are vertically arranged, wherein the first fixing structure 101 (such as Figure 3 As shown) can be located between the mounting edge 73 and the third plate 4013.

[0125] Figure 4B for Figure 1C A structural diagram of the first fixing structure 101 in another perspective.

[0126] like Figure 4B shown, and combined with Figure 4AIn some examples, the first fixing structure 101 includes a limiting recess 108, a mounting edge 73 (such as Figure 4A As shown in FIG, the first connecting frame 401 is located in the limiting recess 108. Therefore, the limiting recess 108 can limit the mounting edge 73, and then limit the first connecting frame 401 to prevent the first connecting frame 401 from shaking.

[0127] For example, the limiting recess 108 may extend along the third direction.

[0128] The limiting recess 108 can be set on the first fixing structure 101 toward the board 30 (such as Figure 2 As shown in FIG, on one side of the positioning frame 401, the limiting recess 108 may be strip-shaped, the depth direction of the limiting recess 108 may be parallel to the first direction, the length direction of the limiting recess 108 may be parallel to the third direction, and the mounting edge 73 may slide along the limiting recess 108 to prevent the first connecting frame 401 from moving along the second direction.

[0129] For example, in Figure 4B In the embodiment, a limiting baffle is provided on one side of the first fixing structure 101 facing the board 30 , and the limiting baffle can be provided along the edge of the heat dissipation opening 107 . Two adjacent limiting baffles can form a limiting recess 108 .

[0130] Figure 5 for Figure 2 FIG. 5 is a structural diagram of the second end 302 of the board 30 and the second connecting frame 501. FIG.

[0131] like Figure 5 As shown, the board 30 is provided with a gold finger connection portion 303, which can be connected to the circuit board 20 (such as Figure 2 As shown) on the board slot 201 (as shown) Figure 2 As shown) plug in, thereby achieving electrical connection between the board card 30 and the circuit board 20.

[0132] The second installation assembly 50 may further include a second connecting frame 501 , which is fixedly connected to the second end 302 of the board 30 .

[0133] Among them, the fixed connection between the second connecting frame 501 and the second end 302 of the board 30 means that after the second connecting frame 501 is connected to the second end 302 of the board 30, no relative displacement will occur between the two. At this time, the second connecting frame 501 and the second end 302 of the board 30 can be detachably connected.

[0134] For example, the second connecting frame 501 is provided with a fifth fixing hole 5015, and the second end 302 of the board 30 is provided with a sixth fixing hole 3020. The computing device 1000 may further include a third fastener 91, which may be sequentially passed through the fifth fixing hole 5015 and the sixth fixing hole 3020 to securely connect the second connecting frame 501 to the second end 302 of the board 30. For example, the third fastener 91 may be a bolt, a screw, a pin, etc., which are not listed here. In addition, the second connecting frame 501 and the second end 302 of the board 30 may also be connected using other connection methods, such as welding, bonding, and clamping, which are not listed here.

[0135] For example, the second connecting frame 501 may include a second connecting body 5011, and the second connecting body 5011 covers the end surface of the second end 302. The second connecting body 5011 may be fixedly connected to the second end 302. It should be noted that the end surface of the second end 302 is a surface of the second end 302 of the board 30 facing the second connecting frame 501. In the computing device 1000, the second connecting body 5011 may be perpendicular to the circuit board 20 (such as Figure 2 shown).

[0136] In some examples, the length of the second connecting body 5011 in the third direction is less than the length of the second connecting body 5011 in the second direction. The fifth fixing hole 5015 is provided on the second connecting body 5011. The number of the fifth fixing holes 5015 can be multiple, and the multiple fifth fixing holes 5015 can be arranged in sequence along the third direction. The length of the end face of the second end 302 of the board 30 in the third direction is less than its length in the second direction, the number of the sixth fixing holes 3020 on the second end 302 of the board 30 can be multiple, and the multiple sixth fixing holes 3020 can be arranged in sequence along the third direction, wherein one sixth fixing hole 3020 is connected to one fifth fixing hole 5015 via one third fastener 91. The second connecting body 5011 and the second end 302 can be connected via multiple third fasteners 91, thereby improving the reliability of the connection between the second connecting body 5011 and the second end 302. Figure 4A In the embodiment, some embodiments of the present application are illustrated by taking the second connection body 5011 having three fifth fixing holes 5015 and the second end 302 having three sixth fixing holes 3020 as an example.

[0137] For example, the plurality of fifth fixing holes 5015 may be evenly arranged, and the plurality of sixth fixing holes 3020 may be evenly arranged.

[0138] like Figure 5As shown, in some examples, the second connection body 5011 may be further provided with at least one avoidance opening 5012, and the second end 302 of the board 30 may be provided with at least one interface 304, wherein one interface 304 is located in one avoidance opening 5012 and may extend from the avoidance opening 5012. Figure 4A In the embodiment, some embodiments of the present application are illustrated by taking the second end 302 provided with an interface 304 and the second connection body 5011 provided with an avoidance opening 5012 as an example.

[0139] Among them, at least one interface 304 may include any one or more of a VGA (Video Graphics Array) interface, a DVI (Digital Visual Interface) interface, an HDMI (High Definition Multimedia Interface) interface, a DP (Display Port) interface, and a USB-Type-C interface.

[0140] like Figure 5 As shown, in some examples, a plurality of heat dissipation holes 5013 are provided on the second connection body 5011 . By providing the heat dissipation holes 5013 on the second connection body 5011 , the board 30 can be cooled, thereby improving the phenomenon of the board 30 being overheated.

[0141] See also Figure 5 In some examples, the second connecting frame 501 may include at least one plug-in portion 5014, which is disposed at one end of the second connecting body 5011, wherein the plug-in portion 5014 may be located between the second connecting body 5011 and the circuit board 20.

[0142] like Figure 2 As shown, a plurality of plug-in ports 1041 are provided on the side of the second beam 104 of the second fixing structure 102 facing away from the circuit board 20, wherein a plug-in portion 5014 (such as Figure 5 By providing multiple plug-in portions 5014, the second connecting frame 501 can be connected to the second fixed structure 102 at multiple points, thereby increasing the reliability of the connection between the second connecting frame 501 and the second fixed structure 102.

[0143] like Figure 5 As shown, for example, a second connecting frame 501 may include two plug-in portions 5014 .

[0144] In some examples, the second connecting frame 501 may further include a second limiting plate 5017. The second connecting body 5011 may include two sides arranged sequentially and opposite to each other along the second direction. The second limiting plate 5017 is connected to one of the sides, and the second limiting plate 5017 extends in the direction of the board 30. For example, the second limiting plate 5017 may be in the shape of a bar, with its length direction being the same as the third direction and its width direction being the same as the first direction. The second limiting plate 5017 may contact the first surface of the board 30, wherein the first surface may be parallel to the YZ plane. By making the second limiting plate 5017 contact the first surface of the board 30, the second limiting plate 5017 limits the board 30 to prevent the board 30 from shaking along the second direction.

[0145] In some examples, the second connecting frame 501 may further include a fixing plate 5018. The second connecting body 5011 may include two sides arranged sequentially and opposite to each other along the second direction, and the fixing plate 5018 may be connected to one of the sides. In some examples, the fixing plate 5018 and the second limiting plate 5017 may be respectively arranged on opposite sides of the second connecting body 5011. In this case, the board 30 may be located between the second limiting plate 5017 and the fixing plate 5018. For example, the fixing plate 5018 may be connected to the second surface of the board 30. For example, the fixing plate 5018 may be bonded, welded, clamped, or connected to the second surface of the board 30 by means of screws, pins, or other structures.

[0146] In some examples, the second connecting frame 501 may further include a second connecting plate 5016, which is connected to a side of the second connecting body 5011 away from the circuit board 20, and the second connecting plate 5016 extends in a direction away from the second end 302. In some examples, the second connecting plate 5016 may be arranged perpendicular to the second connecting body 5011. Of course, in some other examples, the second connecting plate 5016 may have other angles with the second connecting body 5011, such as an acute angle or an obtuse angle. The second connecting plate 5016 may be located on the second fixed structure 102 (e.g., Figure 2 shown) facing away from the side of the circuit board 20.

[0147] Figure 6 It is a structural diagram of the board 30 , the second connecting frame 501 and the second fixing structure 102 .

[0148] like Figure 6As shown, in some examples, a limiting notch 5016A is provided on the side of the second connecting plate 5016 away from the board 30, and a limiting protrusion 102A can be provided on the second fixed structure 102, and the limiting protrusion 102A is located in the limiting notch 5016A, so that the second connecting plate 5016 can be limited to limit the movement of the second connecting plate 5016 along the second direction.

[0149] A second fixing lug is provided at each end of the second fixing structure 102 in the second direction. The second fixing lug can be fixed to the chassis 10 via the second fixing lug. For example, the second fixing lug is provided with a first mounting hole, and the chassis 10 is provided with a second mounting hole. Pins, bolts, screws, and other components can be passed through the first mounting hole and the second mounting hole in sequence to mount the second fixing structure 102 to the chassis 10.

[0150] like Figure 6 As shown, a positioning column 502 is provided on the second fixing structure 102 .

[0151] In some examples, the positioning post 502 can extend along a third direction, wherein the third direction is perpendicular to the first direction and the second direction.

[0152] In some examples, the positioning post 502 can be disposed on a side of the second fixing structure 102 facing away from the circuit board 20. For example, the positioning post 502 can be disposed on the first beam 103 (eg, Figure 1D shown) facing away from the side of the circuit board 20.

[0153] The second connecting frame 501 is provided with a first limiting hole 5010 , which is used for the positioning post 502 to pass through. The positioning post 502 can be located in the first limiting hole 5010 to limit the second end 302 of the board 30 .

[0154] For example, the first limiting hole 5010 can be set on the second connecting plate 5016.

[0155] In some examples, the positioning column 502 on the second fixed structure 102 can extend along the third direction and extend from the first limiting hole 5010. Therefore, the positioning column 502 can limit the second connecting frame 501 to restrict the movement of the second connecting frame 501 in the XY plane.

[0156] The positioning post 502 is fixedly connected to the second fixing structure 102. In this case, after the positioning post 502 is connected to the second fixing structure 102, relative movement does not occur. For example, the positioning post 502 and the second fixing structure 102 can be detachably connected or non-detachably connected. For example, the positioning post 502 and the second fixing structure 102 can be connected by means of clamping, welding, or bonding. In addition, the positioning post 502 can also be integrally formed with the second fixing structure 102. For another example, one end of the positioning post 502 can be provided with a thread, and the second fixing structure 102 is provided with a threaded hole, and the positioning post 502 can be installed in the threaded hole.

[0157] Among them, a first limiting hole 5010 is provided on the second connecting frame 501. When installing the board 30, the positioning column 502 can pass through the first limiting hole 5010. At this time, the positioning column 502 can be located in the first limiting hole 5010, and then the positioning column 502 can limit the board 30, thereby preventing the board 30 and the second connecting frame 501 from moving in a direction perpendicular to the third direction. In this way, the board 30 can be installed without using installation tools, thereby speeding up the installation speed of the board 30.

[0158] For example, the first limiting hole 5010 can be set on the second connecting plate 5016.

[0159] Figure 7 for Figure 2 A structural diagram of the computing device 1000 from another perspective.

[0160] like Figure 7 As shown, the second mounting assembly 50 may further include an elastic locking assembly 503. The elastic locking assembly 503 is mounted on the second fixing structure 102. Under the action of elastic force, the elastic locking assembly 503 engages with the positioning post 502, thereby preventing the second connecting frame 501 from separating from the positioning post 502. This prevents the board 30 and the second connecting frame 501 connected to the board 30 from falling off the second fixing structure 102, thereby further stabilizing the connection between the board 30 and the second connecting frame 501 connected to the board 30 and the second fixing structure 102. Furthermore, under the action of elastic force, the elastic locking assembly 503 secures the second connecting frame 501 to the second fixing structure 102, thereby simplifying the installation process of the board 30.

[0161] like Figure 7 As shown, in some embodiments, the elastic locking assembly 503 may include a first fixing member 81 , a first movable member 82 , a second movable member 83 and a first elastic member 84 .

[0162] The first fixing member 81 is fixed on the second fixing structure 102, and the first movable member 82 is movably connected to the first fixing member 81; a second limiting hole (not shown in the figure) is provided on the first movable member 82, and the second limiting hole is used for allowing the positioning column 502 to pass through, so that the first movable member 82 is arranged on the surface of the second connecting frame 501 facing away from the second fixed structure 102.

[0163] The first fixing member 81 being fixed to the second fixing structure 102 means that the first fixing member 81 is fixedly connected to the second fixing structure 102. In this case, after the first fixing member 81 and the second fixing structure 102 are connected, there is no relative movement between the two. For example, the first fixing member 81 and the second fixing structure 102 can be connected by welding, clamping, or threading.

[0164] The first movable member 82 and the first fixed member 81 are movably connected to each other, which means that after the first movable member 82 is connected to the first fixed member 81, the relative positional relationship between the two can be changed. For example, the first movable member 82 can rotate around the first fixed member 81. For example, when the first movable member 82 rotates around the first fixed member 81, the first movable member 82 can rotate relative to the first fixed member 81.

[0165] Among them, the first fixing member 81 can move between the first position and the second position. When the first fixing member 81 is in the first position, the first movable member 82 is away from the board 30. At this time, it is convenient for the user to insert the board 30 connected to the second connecting frame 501 between the first fixed structure 101 and the second fixed structure 102. The first movable member 82 can be rotated from the first position to the second position. At this time, the positioning column 502 is located in the second limiting hole, and the first movable member 82 is provided on the surface of the second connecting frame 501 facing away from the second fixed structure 102, thereby limiting the second connecting frame 501. Among them, Figure 7 The first movable member 82 is shown in the second position, and the first movable member 82 is not shown in the first position. When the first movable member 82 rotates in the direction indicated by the arrow F3, the first movable member 82 can move from the second position to the first position.

[0166] In some examples, the first movable member 82 may be plate-shaped. When the first movable member 82 is disposed on the surface of the second connecting frame 501 facing away from the second fixed structure 102 , the first movable member 82 may cover the surface of the second connecting frame 501 facing away from the second fixed structure 102 .

[0167] At the second end 302 (eg Figure 6 As shown) through the second connecting frame 501 (as Figure 6After the first movable member 82 is installed on the second fixed structure 102, the first movable member 82 can be operated so that the first movable member 82 presses on the second connecting frame 501, and then the first movable member 82 can limit the second connecting frame 501 to prevent the first movable member 82 from moving along the third direction. For example, the first movable member 82 presses on the second connecting plate 5016 (as shown in FIG. Figure 6 As shown), at this time, the second connecting plate 5016 is located between the first movable member 82 and the second fixed structure 102.

[0168] The second movable member 83 is elastically connected to the first movable member 82 via a first elastic member 84. The first elastic member 84 can provide elastic force for the elastic locking assembly 503.

[0169] The second movable member 83 is provided with a locking hole 830 .

[0170] Figure 8 for Figure 7 Structural diagram of the elastic locking assembly 503.

[0171] like Figure 8 As shown, the locking hole 830 may include a locking area 8301 and a passing area 8302 , and the locking area 8301 is in communication with the passing area 8302 .

[0172] For example, the locking area 8301 and the passing area 8302 are arranged in sequence along the second direction.

[0173] like Figure 6 As shown, the positioning column 502 may include a column 5021 and a lock head 5022. One end of the column 5021 is fixedly connected to the second fixing structure 102, and the other end of the column 5021 is fixedly connected to the lock head 5022. The radial dimension of the lock head 5022 is larger than the radial dimension of the column 5021. Figure 8 As shown) is used for the lock head 5022 and the cylinder 5021 to pass through; the locking area 8301 (as shown) Figure 8 5021 and restricting the passage of the lock head 5022.

[0174] like Figure 7 As shown, the second movable member 83 is elastically connected to the first movable member 82 via the first elastic member 84, so the positional relationship between the second movable member 83 and the first movable member 82 can change. The first elastic member 84 abuts against the second movable member 83 to limit the column 5021 to the locking area 8301. Figure 7 As shown, in Figure 7 In the figure, some embodiments of the present application are illustrated by taking the positioning column 502 located in the locking area 8301 as an example.

[0175] Among them, through area 8302 (such as Figure 8As shown) for the lock head 5022 and the column 5021 to pass through, it can be understood that when the positioning column 502 is located in the passing area 8302, the positioning column 502 cannot limit the second movable member 83. At this time, the second movable member 83 can move and the second movable member 83 can move to escape the restriction of the positioning column 502. When the positioning column 502 is located in the locking area 8301 (as shown) Figure 8 As shown), since the locking area 8301 allows the column 5021 to pass through but cannot allow the lock head 5022 to pass through, the second movable member 83 cannot escape the restriction of the positioning column 502. At this time, the positioning column 502 can limit the second movable member 83.

[0176] For example, the lock head 5022 is connected to one end of the column 5021 to form a dividing interface. When the positioning column 502 is located in the locking area 8301, the dividing interface of the lock head 5022 can be pressed on the second movable member 83, so that the second movable member 83 can be pressed on the first movable member 82 to limit the first movable member 82, and the second connecting frame 501 (such as Figure 6 As shown) and board 30 (as Figure 6 , as shown) is fixed to the second fixed structure 102.

[0177] like Figure 8 As shown, for example, the locking area 8301 and the passing area 8302 have different widths in the first direction, so that the locking area 8301 and the passing area 8302 can allow different structures of the positioning column 502 to pass through.

[0178] like Figure 7 As shown, the positioning column 502 can sequentially pass through the second connecting frame 501 (as shown in FIG. Figure 6 The first limiting hole 5010 (as shown) Figure 6 ), the second limiting hole of the first movable member 82 and the locking hole 830 of the second movable member 83. The first movable member 82 and the second movable member 83 can both be plate-shaped. When the fixing post is located in the locking area 8301, the second movable member 83 can press on the first movable member 82 to limit the first movable member 82.

[0179] In some examples, the first elastic member 84 can generate an elastic force on the second movable member 83 along the locking area 8301 (eg Figure 8 ) points to through area 8302 (as shown Figure 8 As shown in the figure, Figure 8 As shown, the direction indicated by arrow F1 is the direction from the locking area 8301 to the passing area 8302. At this time, the first elastic member 84 can be in a compressed state. The elastic locking assembly 503 can position the positioning column 502 in the locking area 8301 under the elastic force of the first elastic member 84, thereby aligning the second movable member 83, the first movable member 82, and the second connecting frame 501 (as shown in FIG. Figure 6 As shown in FIG, the second end 302 of the board 30 is fixed to the second fixing structure 102, thereby achieving tool-free installation of the board 30.

[0180] When the board 30 is disassembled, the second movable member 83 can be moved toward the passing area 8302 (eg Figure 8 As shown) points to the locking area 8301 (as shown) Figure 8 As shown in the direction of movement, Figure 8 As shown, the direction indicated by arrow F2 is the direction from the passage area 8302 to the locking area 8301. This further compresses the first elastic member 84, changing the relative position between the second movable member 83 and the positioning post 502, allowing the positioning post 502 to enter the passage area 8302 from the locking area 8301. The positioning post 502 is no longer able to limit the second movable member 83, and the second movable member 83 loses its limiting effect on the first movable member 82. At this time, operating the first movable member 82 can move it away from the second connecting frame 501, so that the first movable member 82 no longer presses on the second connecting frame 501, allowing the user to remove the board 30 from the board mounting position. Therefore, when the user disassembles the board 30, he only needs to move the position of the second movable part 83 to make the positioning column 502 disengage from the locking area 8301 and enter the passing area 8302, so that the second movable part 83 no longer limits the first movable part 82, and then move the first movable part 82 so that the first movable part 82 no longer presses on the second connecting frame 501, so that the elastic locking assembly 503 no longer limits the second connecting frame 501, which makes it convenient for the user to disassemble the board 30 and realizes tool-free disassembly of the board 30.

[0181] like Figure 7 and Figure 8 As shown, in some examples, the first movable member 82 is in a bar shape, and in this case, the length direction of the first movable member 82 is the same as the second direction.

[0182] In some examples, the second movable member 83 is in a bar shape, and in this case, the length direction of the second movable member 83 is the same as the second direction.

[0183] The first movable member 82 may include two ends opposite to each other along the second direction, one end of which is provided with a third fixing ear plate 821 . The third fixing ear plate 821 protrudes from a surface of the first movable member 82 facing away from the second fixing structure 102 .

[0184] The second movable member 83 may include two opposite ends disposed along the second direction, with a fourth fixing lug 831 disposed at one end proximal to the third fixing lug 821. One end of the first elastic member 84 is connected to the third fixing lug 821, and the other end is connected to the fourth fixing lug 831, thereby securing the first elastic member 84.

[0185] In some embodiments, the first elastic member 84 may include a compression spring or a tension spring, wherein the compression spring or the tension spring has a lower cost.

[0186] like Figure 6 As shown, in some embodiments, the computing device 1000 may include multiple boards 30 arranged in sequence along the second direction, one board 30 is connected to a second connecting frame 501, wherein the multiple second connecting frames 501 connected to the multiple boards 30 are all connected to the second fixed structure 102.

[0187] At this time, multiple positioning columns 502 can be set on the second fixed structure 102. The multiple positioning columns 502 are arranged at intervals and arranged in sequence along the extension direction of the second fixed structure 102 (i.e., the X-axis direction). One positioning column 502 can pass through a first limiting hole 5010 of a second connecting frame 501.

[0188] like Figure 7 As shown, in other examples, the projection of the first movable member 82 in the third direction can cover the projection of at least one second connecting frame 501 in the third direction. When the positioning column 502 passes through the first limiting hole 5010 (such as Figure 6 As shown), a first movable member 82 can be pressed on at least one second connecting frame 501.

[0189] For example, a first movable member 82 may be pressed onto a second connecting frame 501 . At this time, an elastic locking assembly 503 may fix the second connecting frame 501 and the second end 302 of a board 30 onto the second fixing structure 102 .

[0190] For example, a first movable member 82 can press on multiple second connecting frames 501, so that an elastic locking assembly 503 can lock multiple boards 30, and when the positioning column 502 is located in the through area 8302 of the locking hole 830, the elastic locking assembly 503 can simultaneously release the locks on two second connecting frames 501 and two boards 30, so that at least two boards 30 can be disassembled. Figure 7 In the embodiment, some embodiments of the present application are illustrated by taking an example in which a first movable member 82 can press on two second connecting frames 501. In some embodiments of the present application, there is no limit on the number of second connecting frames 501 that the first movable member 82 can cover.

[0191] For example, the number of locking holes 830 on a movable member 83 may be the same as the number of second connecting frames 501 it covers.

[0192] like Figure 7 As shown, in some embodiments, the elastic locking assembly 503 can also rotate the shaft 5041.

[0193] The first fixed member 81 may include a first rotation hole, and the first movable member 82 may include a second rotation hole. The rotation shaft 5041 is disposed in the first rotation hole and the second rotation hole to enable the first movable member 82 to rotate relative to the first fixed member. In this case, the position of the first movable member 82 can be changed by flipping the first movable member 82.

[0194] The rotating shaft 5041 can be disposed in the first rotating hole and the second rotating hole, so that the first movable member 82 can be rotatably connected to the first fixed member 81 via the rotating shaft 5041. When the user installs the board 30, the first movable member 82 can be rotated so that the first movable member 82 presses on the second connecting frame 501. When the user removes the board 30, the user can rotate the first movable member 82 so that the first movable member 82 moves away from the second connecting frame 501 and no longer presses on the second connecting frame 501, thereby removing the second connecting frame 501 and the board 30. The rotatable connection of the first movable member 82 to the first fixed member 81 via the rotating shaft 5041 facilitates the user's operation of the first movable member 82 so that the first movable member 82 presses on the second connecting frame 501, or moves the first movable member 82 away from the second connecting frame 501 and no longer presses on the second connecting frame 501.

[0195] In addition, the first movable member 82 is rotatably connected to the first fixed member 81 via the rotating shaft 5041 , so that the first movable member 82 is prevented from falling when the first movable member 82 is no longer pressed against the second connecting frame 501 .

[0196] For example, the axial direction of the rotating shaft 5041 may be the same as the second direction. In particular, the axial directions of the first rotating hole and the axial directions of the second rotating hole are both the same as the second direction.

[0197] In some examples, a first movable member 82 may include a plurality of second rotation holes, and the rotation shaft 5041 may pass through the plurality of second rotation holes, thereby making the connection between the rotation shaft 5041 and the first movable member 82 more stable.

[0198] Figure 9 for Figure 8 A structural diagram of the elastic locking component 503 from another perspective.

[0199] See also Figure 9The first movable member 82 may include a first rotating body 822 and a first rotating portion 823. The first rotating portion 823 is connected to the first rotating body 822. The first rotating body 822 may be plate-shaped and may be pressed against the second connecting plate 5016 of the second connecting frame 501. The first rotating portion 823 may be provided with a second rotating hole.

[0200] The first rotating body 822 may be in a bar shape and extend along the second direction. The first rotating portion 823 may be in a bar shape and extend along the second direction.

[0201] In some examples, the first movable member 82 may include a plurality of first rotating parts 823, the plurality of first rotating parts 823 are sequentially arranged along the second direction, and the plurality of first rotating parts 823 are all connected to the first rotating body 822. Figure 9 In the embodiment, some embodiments of the present application are illustrated by taking the example that the first movable member 82 may include three first rotating parts 823.

[0202] In some examples, the rotating shaft 5041 and the first fixing member 81 may be located on a side of the second movable member 83 away from the board 30 .

[0203] Please refer again Figure 7 The second fixing structure 102 may include a bearing surface 1021 and a mounting surface 1022. The bearing surface 1021 is the second fixing structure 102 away from the circuit board 20 (eg Figure 2 As shown in FIG, the mounting surface 1022 is connected to an edge of the bearing surface 1021 away from the board 30.

[0204] For example, the bearing surface 1021 may be located on the first beam 103. In this case, the bearing surface 1021 may be the first beam 103 (e.g. Figure 1D ) away from the connecting beam 105 (as shown) Figure 1D a surface shown).

[0205] The first fixing member 81 can be fixed on the mounting surface 1022 of the second fixing structure 102 .

[0206] In some examples, the first fixing member 81 may include a first fixing portion 811 and a first mounting portion 812, wherein the first fixing portion 811 is mounted on the mounting surface 1022 of the second fixing structure 102. For example, the first fixing portion 811 may be plate-shaped and may be attached to the mounting surface 1022, and the first fixing portion 811 may be fixed to the mounting surface 1022. For example, the first fixing portion 811 and the second fixing structure 102 may be fixedly connected by welding, clamping, or the like. Furthermore, the first fixing portion 811 and the second fixing structure 102 may also be connected by pins, screws, bolts, or the like.

[0207] For example, the first fixing portion 811 is in a strip shape, and the extending direction of the first fixing portion 811 is the same as the second direction.

[0208] The first mounting portion 812 is provided with a first rotation hole. The number of first mounting portions 812 can be one or more, with one first rotation hole provided on each first mounting portion 812. The rotation shaft 5041 can sequentially pass through the first rotation holes of multiple first mounting portions 812 on a first fixing member 81, thereby increasing the reliability of the connection between the rotation shaft 5041 and the first fixing member 81. The axial direction of the first rotation hole is the same as the second direction.

[0209] For example, the first fixing member 81 may include four first mounting portions 812 .

[0210] In some embodiments, the elastic locking assembly 503 may also include a second elastic member (not shown in the figure). When the column 5021 is located in the passing area 8302, under the action of the elastic force of the second elastic member, the locking hole 830 and the second limiting hole are both separated from the positioning column 502.

[0211] Among them, by setting a second elastic member, when the positioning column 502 is located in the passing area 8302, the locking hole 830 and the second limiting hole can automatically disengage from the positioning column 502, that is, the second movable member 83 and the first movable member 82 automatically disengage from the positioning column 502, so that the first movable member 82 no longer presses on the second connecting frame 501, and the second connection cannot be limited, thereby realizing automatic unlocking of the elastic locking assembly 503 and accelerating the disassembly speed of the board 30.

[0212] In some embodiments, the second elastic member may include a torsion spring.

[0213] The torsion spring may include a first connecting end and a second connecting end, and the first connecting end and the second connecting end are respectively connected to the first movable member 82 and the second fixed structure 102 .

[0214] Among them, the torsion spring has a lower cost.

[0215] like Figure 7 and Figure 8 As shown, in some embodiments, the elastic locking assembly 503 may further include a limiting post 505. The limiting post 505 is fixed on the first movable member 82.

[0216] For example, the extending direction of the limiting column 505 is the same as the third direction.

[0217] In some examples, the limiting post 505 can be detachably connected to the first movable member 82 , for example, the limiting post 505 can be threadedly connected to the first movable member 82 . In another example, the limiting post 505 can be snap-fitted to the first movable member 82 .

[0218] The second movable member 83 is provided with a limiting slot 832 , which is slidably connected to the limiting column 505 to limit the sliding direction of the second movable member 83 relative to the first movable member 82 , thereby facilitating the user to control the moving direction of the second movable member 83 .

[0219] In some examples, when disassembling the board 30 , the second movable member 83 needs to be moved in a direction from the passing area 8302 to the locking area 8301 , wherein the direction from the passing area 8302 to the locking area 8301 is parallel to the second direction.

[0220] In some examples, the limiting sliding groove 832 may be in a bar shape, and the limiting sliding groove 832 may extend along the second direction, that is, the length direction of the limiting sliding groove 832 is the second direction.

[0221] When the second movable part 83 slides relative to the first movable part 82, the second movable part 83 can move along the second direction. By setting the limiting groove 832 and the limiting column 505, the sliding direction of the second movable part 83 can be limited, thereby preventing the second movable part 83 from deviating from the second direction when sliding, and ensuring that the positioning column 502 can enter the passing area 8302 from the locking area 8301.

[0222] like Figure 8 As shown, in some embodiments, the limiting column 505 may include a limiting flange 5051 extending radially along the limiting column 505 , and the limiting flange 5051 is used to limit the limiting sliding groove 832 from separating from the limiting column 505 .

[0223] For example, one end of the limiting post 505 is fixedly connected to the first movable member 82 , and the limiting flange is located at the end of the limiting post 505 away from the first movable member 82 .

[0224] The length direction of the limiting slide groove 832 is the second direction, and the width direction of the limiting slide groove 832 is the first direction. The maximum width of the limiting flange 5051 in the first direction is greater than the width of the limiting slide groove 832 in the first direction. In this case, the edge of the orthographic projection of the limiting flange 5051 on the second movable member 83 is located outside the edge of the limiting slide groove 832.

[0225] By providing a limiting flange on the limiting column 505 , the limiting slide 832 can be limited from separating from the limiting column 505 , thereby preventing the second movable member 83 from separating from the limiting column 505 , thereby improving the reliability of the connection between the second movable member 83 and the first movable member 82 .

[0226] like Figure 7 and Figure 8As shown, in some embodiments, the elastic locking assembly 503 may further include an operating portion 85 , and the operating portion 85 may include an operating surface 851 , and the operating surface 851 intersects with the second direction.

[0227] The user can apply a force to the operating surface 851 in a direction from the passing area 8302 to the locking area 8301 (i.e., the direction indicated by arrow F2), thereby causing the positioning post 502 to enter the passing area 8302. The direction from the passing area 8302 to the locking area 8301 is parallel to the second direction, and the operating surface 851 intersects the second direction. Therefore, it is convenient for the user to apply a force to the second movable member 83 in a direction from the passing area 8302 to the locking area 8301.

[0228] In some examples, the operating surface 851 may be perpendicular to the second direction.

[0229] For example, the number of the operating surfaces 851 may be one or two.

[0230] In some examples, the operating portion 85 may be plate-shaped, in which case two surfaces of the operating portion 85 facing each other in the second direction may serve as two operating surfaces 851. When there are two operating surfaces 851, it is convenient for the user to apply pressure to the operating portion 85.

[0231] In addition, the operating portion 85 may also have other structures. Another structure of the operating portion 85 is introduced below.

[0232] like Figure 8 As shown, in some embodiments, in the operating portion 85, there are two operating surfaces 851, which are arranged opposite to each other. In this case, the two operating surfaces 851 can face different directions.

[0233] The operating portion 85 may further include a connecting surface 852, the connecting surface 852 connecting the two operating surfaces 851, and an indicator mark 853 provided on the connecting surface 852, the indicator mark 853 being used to indicate the pressing direction of the second movable member 83. After applying pressure to the second movable member 83 in the pressing direction indicated by the indicator mark 853, the cylinder 5021 (such as Figure 7 shown) is located in pass zone 8302.

[0234] In some examples, the connection surface 852 may be perpendicular to the third direction.

[0235] In some examples, the operating portion 85 may include a first operating plate, a second operating plate, and a connecting plate. One end of the first operating plate is connected to a surface of the second movable member 83 facing away from the first movable member 82. One end of the second operating plate is connected to a surface of the second movable member 83 facing away from the first movable member 82. The first operating plate and the second operating plate are spaced apart. The connecting plate has two ends in the second direction connected to an end of the first operating plate facing away from the second movable member 83 and an end of the second operating plate facing away from the second movable member 83, respectively.

[0236] Among them, a surface of the first operating plate facing away from the second operating plate can serve as an operating surface 851 , a surface of the second operating plate facing away from the first operating plate can serve as another operating surface 851 , and a surface of the connecting plate facing away from the second movable member 83 can serve as a connecting surface 852 .

[0237] For example, the first operating plate and the second operating plate may both be perpendicular to the second direction, while the connecting plate is perpendicular to the third direction.

[0238] Among them, pressing the second movable member 83 along the pressing direction indicated by the indicator mark 853 can make the second movable member 83 move in the direction from the passing area 8302 to the locking area 8301, thereby making the positioning column 502 (such as Figure 7 By setting the indicator mark 853, the user can adjust the position of the second movable member 83.

[0239] For example, the indicator mark 853 may be in the shape of a triangle, with one sharp corner of the triangle pointing in the pressing direction.

[0240] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that a person skilled in the art can conceive within the technical scope disclosed in this application should be included within the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
