Description

[0001] This application claims priority to Chinese patent application No. 202310028075.X, filed on January 9, 2023, entitled "Circuit Board Module and Electronic Equipment", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of computing technology, and more particularly to a computing device. Background Technology

[0003] With the rise of big data, cloud computing, and AI (Artificial Intelligence), the application demand for computing devices such as servers and supercomputers is becoming increasingly widespread. Among these applications, there are scenarios involving dual-layer boards. However, the current connection methods for dual-layer boards are complex, and the disassembly and assembly of these boards consume significant time and space within the computing device. How to achieve rapid installation and disassembly of dual-layer boards while maintaining connectivity remains a subject of ongoing exploration in the industry. Summary of the Invention

[0004] Embodiments of this application provide a computing device that enables rapid installation and removal of dual-layer single-board connections.

[0005] In a first aspect, embodiments of this application provide a computing device, comprising:

[0006] First circuit board;

[0007] A module bracket, which is stacked and connected to the first circuit board, and the module bracket is provided with a first connecting portion; and

[0008] A circuit board module is stacked on the side of the module support away from the first circuit board. The circuit board module includes a second circuit board and a movable component. The second circuit board and the movable component are stacked and connected. The movable component is provided with a second connecting part.

[0009] The first connecting part and the second connecting part have a locked state and an unlocked state;

[0010] When the first connecting part and the second connecting part are in the first position, the first connecting part and the second connecting part are in the locked state, so that the first circuit board and the second circuit board are fixedly connected; when the movable part slides to make the first connecting part and the second connecting part in the second position, the first connecting part and the second connecting part are in the unlocked state, so that the first circuit board and the second circuit board can be disengaged from each other.

[0011] The computing device provided in this application embodiment allows a movable component in the circuit board module to move relative to the module bracket, thereby changing the relative position of the second connecting portion on the movable component and the first connecting portion on the module bracket, so that the first connecting portion and the second connecting portion switch between a locked state and an unlocked state. When the first connecting portion and the second connecting portion are in the first position, the movable component can be fixedly connected to the module bracket, and the first circuit board can be electrically connected to the second circuit board. When the first connecting portion and the second connecting portion are in the second position, the movable component can be disengaged from the module bracket, and the first circuit board and the second circuit board can be disconnected. This application enables rapid installation and disassembly of the circuit board module and the module bracket by moving the movable component.

[0012] Furthermore, when the circuit board module is replaced as an independent unit, it can be maintained separately, thereby reducing maintenance costs, saving maintenance time, and simplifying the maintenance process. It also avoids the use of numerous screws and nuts, reducing the difficulty of connecting the circuit board module to the module bracket, saving on the assembly cost of the computing device, and significantly reducing the time spent connecting the circuit board module to the module bracket.

[0013] In one possible implementation, one of the first connecting portion and the second connecting portion is a module connecting pin, and the other of the first connecting portion and the second connecting portion is a groove;

[0014] The slide includes a first annular groove and a second annular groove that are connected to each other. The first annular groove and the second annular groove are arranged and connected along a first direction. The first direction is a direction perpendicular to the stacking direction of the circuit board module and the module support. The size of the first annular groove is larger than the size of the second annular groove.

[0015] The module connecting pin includes a connecting post and an end. One end of the connecting post is connected to the end. The cross-sectional dimension of the end is larger than that of the connecting post. The cross-sectional dimension of the end is smaller than that of the first annular groove. The cross-sectional dimension of the end is larger than that of the second annular groove.

[0016] The connecting post can slide from the first annular groove to the second annular groove. When the sliding groove and the module connecting pin are in the first position, the connecting post is located in the second annular groove; when the sliding groove and the module connecting pin are in the second position, the connecting post is located in the first annular groove.

[0017] Understandably, in one approach, the slide rail can be located on the module bracket, and the module connecting pin can be located on the movable part of the circuit board module. In another approach, the module connecting pin can be located on the module bracket, and the slide rail can be located on the movable part of the circuit board module. The slide rail and the module connecting pin slide relative to each other to connect the module bracket and the circuit board module.

[0018] In the actual assembly process, the end passes through the first annular groove of the slide, and then the movable part moves, so that the connecting column slides into the second annular groove. The groove wall of the second annular groove can limit the connecting column.

[0019] In one possible implementation, the circuit board module further includes a backing plate and an elastic element. The backing plate is connected between the second circuit board and the movable element. One end of the elastic element is connected to the backing plate, and the other end of the elastic element is connected to the movable element. The movable element is capable of moving relative to the backing plate along the first direction to deform the elastic element.

[0020] Understandably, when the circuit board module detaches from the module bracket, the elastic element of the circuit board module can recover from the state of elastic deformation to its initial state. At this time, it can be ensured that when the circuit board module is connected to the module bracket again, the moving part moves relative to the liner, and then directly connects with the module bracket; the first annular groove corresponds to the position of the module connecting pin, and the first circuit board can correspond to the position of the second circuit board.

[0021] In one possible implementation, the liner includes a first abutment portion, the movable member includes a second abutment portion, the first abutment portion and the second abutment portion are disposed opposite to each other in the first direction, one end of the elastic member is connected to the first abutment portion, and the other end of the elastic member is connected to the second abutment portion.

[0022] It is understood that both the first and second abutting portions extend in the stacking direction of the circuit board module and the module bracket, and are arranged opposite to each other, thereby providing installation space for the elastic element. When the elastic element is compressed, the elastic force generated by the elastic element can be transmitted to the liner and the movable part through the first and second abutting portions respectively, thereby causing the liner and the movable part to move relative to each other.

[0023] In one possible implementation, a first positioning post is provided on the surface of the first abutting part facing the second abutting part, and a second positioning post is provided on the surface of the second abutting part facing the first abutting part. The first positioning post and the second positioning post are arranged opposite to each other. One end of the elastic member is sleeved on the first positioning post, and the other end of the elastic member is sleeved on the second positioning post.

[0024] It is understandable that the first positioning post and the second positioning post can provide a fitting position for the elastic element. The first positioning post and the second positioning post are located at both ends of the elastic element and limit the elastic element.

[0025] In one possible implementation, when the first connecting portion and the second connecting portion are in the unlocked state, the elastic element is in the initial state; when the first connecting portion and the second connecting portion are in the locked state, the elastic element is in a stretched state or a compressed state.

[0026] In one possible implementation, the first abutting portion includes a first abutting surface and a second abutting surface disposed opposite to each other along a first direction; the second abutting portion is opposite to the first abutting surface, the first connecting portion and the second connecting portion are in the unlocked state, and the elastic member has a first length; when the first connecting portion and the second connecting portion are in the locked state, the elastic member is compressed, and the elastic member has a second length, the second length being less than the first length;

[0027] Alternatively, the second abutting portion is opposite to the second abutting surface, the first connecting portion and the second connecting portion are in the unlocked state, and the elastic member has a third length; the first connecting portion and the second connecting portion are in the locked state, the elastic member is stretched, and the elastic member has a fourth length, the fourth length being greater than the third length.

[0028] In one possible implementation, the circuit board module further includes a connector that passes through the movable member to be fixedly connected to the liner, and the connector is slidable relative to the movable member.

[0029] Understandably, one end of the connector can be fixedly connected to the liner, and the other end of the connector can be slidably connected to the movable part, so that the movable part can slide relative to the liner.

[0030] In one possible implementation, the movable component is provided with a connecting groove that penetrates the movable component in the thickness direction. The connecting component includes a first segment, a second segment, and a third segment. The second segment is located between the first segment and the third segment. The cross-sectional dimension of the second segment is larger than that of the first segment and smaller than that of the third segment. The first segment is fixedly connected to the liner. The second segment passes through the connecting groove. The third segment is capable of abutting against the surface of the movable component opposite to the liner.

[0031] Understandably, the position of the connecting groove of the movable part corresponds to that of the connector. The connector passes through the movable part and the liner. The connector can slide within the connecting groove. The third section of the connector can limit the movement of the movable part, preventing it from detaching from the liner in the first direction.

[0032] In one possible implementation, the module bracket is provided with a module connection hole, and the computing device further includes a fixing member through which the movable member passes; the first connecting part and the second connecting part are in the locked state, and the fixing member is fixed to the hole wall of the module connection hole so that the movable member is connected to the module bracket.

[0033] Understandably, the fasteners can make the connection between the module bracket and the circuit board module more stable, and the fasteners can also prevent the moving parts from moving relative to the backing plate under the action of the elastic parts.

[0034] In one possible implementation, the fastener includes an end portion, a first segment, and a second segment. The end portion and the second segment are respectively connected to opposite ends of the first segment. The cross-sectional dimension of the end portion is larger than the diameter of the first segment, and the diameter of the second segment is larger than the diameter of the first segment. The first segment passes through the movable member. The end portion is engaged with the surface of the movable member away from the module bracket, and the second segment is engaged with the surface of the movable member facing the module bracket. The first connecting portion and the second connecting portion are in the locked state, the second segment is fixedly connected to the module bracket, and the first connecting portion and the second connecting portion are in the unlocked state, whereby the fastener is disengaged from the module bracket.

[0035] In one possible implementation, the fastener is a captive screw. It is understood that using captive screws simplifies the assembly process of the computing device, preventing the fastener from detaching from the moving parts during assembly.

[0036] In one possible implementation, the computing device further includes:

[0037] The housing includes a first side plate, a second side plate, and side plate connecting pins, wherein the first side plate and the second side plate are disposed opposite to each other; and

[0038] A power supply bracket, including a bracket connecting pin, the power supply bracket being connected to the side of the first side plate facing the second side plate;

[0039] The side plate connecting pin includes a first connecting post and a first end, the first connecting post being connected to the side of the second side plate facing the power bracket, and the first end being connected to the end of the first connecting post away from the second side plate;

[0040] The bracket connecting pin includes a second connecting post and a second end, the second connecting post being connected to the side of the power bracket facing the second side plate, and the second end being connected to the end of the second connecting post away from the power bracket;

[0041] The module bracket further includes a first baffle and a second baffle, which are arranged opposite to each other. The first baffle has a first sliding groove, and the second baffle has a second sliding groove. The bracket connecting pin is inserted into the first sliding groove to connect the power supply bracket to one side of the module bracket, and the side plate connecting pin is inserted into the second sliding groove to connect the second side plate to the opposite side of the module bracket.

[0042] Understandably, once the bracket connecting pins and side plate connecting pins are aligned with the first and second sliding grooves of the module bracket, moving the module bracket can complete the connection between the module bracket and the power supply bracket and the housing, thereby simplifying the installation process of the module bracket.

[0043] In one possible implementation, the first groove includes a first groove and a second groove that are connected to each other. The first groove has an opening, and the second connecting post can pass through the opening of the first groove and engage with the groove wall of the second groove.

[0044] The second groove includes a third groove and a fourth groove that are connected to each other. The third groove has an opening, and the first connecting post can pass through the opening of the third groove and engage with the groove wall of the fourth groove.

[0045] Understandably, the walls of the second and fourth slots can respectively hold the bracket connecting pins and the side plate connecting pins, thereby achieving a fixed connection between the module bracket and the power supply bracket and the housing, avoiding the use of a large number of screws and nuts to fix the module bracket. This saves assembly time for the module bracket, power supply bracket, and housing, and simplifies the assembly process. Attached Figure Description

[0064] For ease of understanding, the terminology used in the embodiments of this application will be explained first.

[0065] And / or: This is simply a way of describing the relationship between related objects. It indicates that there can be three kinds of relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0066] Multiple: refers to two or more.

[0067] Connection: should be interpreted broadly. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through an intermediary.

[0068] The specific embodiments of this application will now be clearly described in conjunction with the accompanying drawings.

[0069] Please see Figure 1 , Figure 1 This is a partial structural schematic diagram of the computing device 1000 provided in an embodiment of this application, wherein the circuit board module 200 is mounted on the module bracket 130. The X direction is the width direction of the computing device 1000, the Y direction is the length direction of the computing device 1000, and the Y direction is also a first direction of the computing device 1000, which is perpendicular to the stacking direction of the circuit board module and the module bracket as described below. The Z direction is the height direction of the computing device 1000.

[0070] The computing device 1000 includes a module bracket 130 and a circuit board module 200. The circuit board module 200 may be close to the module bracket 130 in the Z direction. Alternatively, the circuit board module 200 may be far away from the module bracket 130 in the Z direction.

[0071] Understandably, computing devices typically have individual motherboards. These motherboards are specifically designed to meet the needs of computing applications, such as environments requiring high stability, high performance, and high compatibility. Because computing devices operate for long periods, under high intensity, and handle massive amounts of data conversion, their power consumption and data throughput are relatively high, placing extremely stringent requirements on their motherboards. Due to the limited area of ​​individual motherboards in computing devices, their efficiency has already encountered technical bottlenecks in hardware architecture design.

[0072] The computing device 1000 of this application embodiment is provided with a double-layer circuit board, namely a second circuit board and a first circuit board 140 as described below. The first circuit board 140 is connected to the module bracket 130, and the circuit board module 200 includes the second circuit board. The second circuit board and the first circuit board 140 are electrically connected, as detailed below. Compared with a single-circuit board computing device 1000, the double-layer circuit board computing device 1000 has stronger information exchange and processing capabilities and higher operational stability.

[0073] It should be noted that, Figure 1 The purpose is to schematically illustrate the connection relationship between the module bracket 130 and the circuit board module 200, and is not to specifically limit the connection position, specific structure, or quantity of each device. Furthermore, the structure illustrated in the embodiments of this application does not constitute a specific limitation on the computing device 1000. In other embodiments of this application, the computing device 1000 includes... Figure 1 This may involve more or fewer components, or combining certain components, or splitting certain components, or different component arrangements. Figure 1 The components shown can be implemented in hardware, software, or a combination of both.

[0074] Please refer to the following: Figure 2 and Figure 3 , Figure 2 yes Figure 1 The diagram shows a partial structural schematic of the computing device, in which the circuit board module 200 is not mounted on the module bracket 130. Figure 3 yes Figure 1 The diagram shows a partial structural representation of the assembled power supply bracket 120 and housing 110. The computing device 1000 also includes the housing 110, the power supply bracket 120, and the first circuit board 140. The housing 110 has a mounting position, and the power supply bracket 120, module bracket 130, and first circuit board 140 are all located at the mounting position of the housing 110. The housing 110, power supply bracket 120, module bracket 130, and first circuit board 140 are all detachably connected. Specifically, the first circuit board 140 can be stacked with the module bracket 130 in the Z-direction. The power supply bracket 120 can be located on the side of the module bracket 130 opposite to the first circuit board 140 in the X-direction.

[0075] It should be noted that in some implementations of this application, the computing device 1000 may not have a housing 110. The embodiments of this application are only illustrative examples of housing the module bracket 130 and the circuit board module 200 within the housing 110, and are not intended to be limiting.

[0076] The housing 110 may include a base plate 111, a first side plate 112, and a second side plate 113. The first side plate 112 and the second side plate 113 are connected to opposite sides of the base plate 111 in the width direction, and are arranged opposite to each other in the X direction. The base plate 111, the first side plate 112, and the second side plate 113 surround to form a mounting space, thereby providing mounting positions for components such as the power supply bracket 120, the module bracket 130, and the first circuit board 140.

[0077] The housing 110 also includes one or more side plate connecting pins 1131. One or more side plate connecting pins 1131 are disposed on the surface of the second side plate 113 facing the opposite direction to the X direction. Specifically, the side plate connecting pin 1131 includes a first connecting post 1132 and a first end 1133. The cross-sectional dimension of the first end 1133 is larger than the cross-sectional dimension of the first connecting post 1132. This cross-sectional dimension can be the cross-sectional area of ​​the maximum cross-section of the first end 1133 or the first connecting post 1132 in the Z direction. That is, in a direction perpendicular to the axial direction of the first connecting post 1132, the maximum cross-section of the first end 1133 is larger than the maximum cross-section of the first connecting post 1132. The first end 1133 is connected to the end of the first connecting post 1132 away from the second side plate 113. For example, there can be two side plate connecting pins 1131, and the two side plate connecting pins 1131 can be spaced apart along the Y direction.

[0078] Please refer to the following: Figure 3 and Figure 4 , Figure 4 yes Figure 2 The diagram shows a three-dimensional structural schematic of the power supply bracket 120. The power supply bracket 120 is located in the mounting space of the housing 110. The power supply bracket 120 is fixedly connected to both the first side plate 112 and the bottom plate 111. The power supply bracket 120 may include one or more bracket connecting pins 121. The one or more bracket connecting pins 121 are located on the side of the power supply bracket 120 opposite to the first side plate 112. For example, the one or more bracket connecting pins 121 are located on the side of the power supply bracket 120 facing the X direction. The bracket connecting pin 121 includes a second connecting post 1211 and a second end 1212. The second end 1212 is connected to the end of the second connecting post 1211 away from the power supply bracket 120. The cross-sectional dimension of the second end 1212 is larger than the cross-sectional dimension of the second connecting post 1211. This cross-sectional dimension can be the cross-sectional area of ​​the largest cross section of the second end 1212 or the second connecting post 1211 in the Z direction. That is, in the direction perpendicular to the axial direction of the second connecting post 1211, the maximum cross-section of the second end 1212 is greater than the maximum cross-section of the first connecting post 1132. For example, there can be two bracket connecting pins 121, and the two bracket connecting pins 121 can be spaced apart along the Y direction on the outer surface of the power supply bracket 120.

[0079] like Figure 2 As shown, one end of the module bracket 130 is connected to the power supply bracket 120, and the other end of the module bracket 130 is fixedly connected to the second side plate 113. The module bracket 130 is provided with a first connecting part 137, which can be a slide groove or a module connecting pin as described below.

[0080] Please refer to the following: Figure 5 and Figure 6 , Figure 5 yes Figure 2 The diagram shown is a structural schematic of the module bracket 130 at one angle. Figure 6 yes Figure 2 A structural schematic diagram of the module bracket 130 from another angle.

[0081] Specifically, the module bracket 130 includes a bracket body 131, a first baffle 132, a second baffle 133, one or more first extension plates 134, one or more second extension plates 135, one or more screws 136, and a first connecting part 137. The first connecting part 137 will be referred to below as the module connecting pin 1370.

[0082] The first baffle 132 and the second baffle 133 are located on opposite sides of the support body 131 in the X direction, and are both set at an angle to the support body 131. Specifically, the first baffle 132 and the second baffle 133 extend from the edge of the support body 131 in the opposite direction to the Z direction, and the angle between the first baffle 132 and the second baffle 133 and the support body 131 can be the angle between the first baffle 132 and the second baffle 133 and the surface of the support body 131 facing the opposite direction to the Z direction. The first baffle 132 and the second baffle 133 can form a 90° angle with the support body 131. The first extension plate 134 is located on the side of the support body 131 facing the Y direction, and is formed by bending and extending away from the support body 131 in the opposite direction to the Z direction. In this embodiment, it is approximately an L-shaped plate. The second extension plate 135 is located on the side of the support body 131 facing the Y direction. The second extension plate 135 and the first extension plate 134 can be alternately arranged along the X direction. The first extension plate 134 and the second extension plate 135 extend to different degrees. The distance the first extension plate 134 extends in the opposite direction of the Z direction is less than the distance the second extension plate 135 extends in the opposite direction of the Z direction. In one implementation, the first circuit board 140 and the module bracket 130 are arranged sequentially in the Z direction. The second extension plate 135 is used to connect with the first circuit board 140; therefore, the second extension plate 135 needs to extend to the first circuit board 140 and contact it, thereby connecting with the first circuit board 140. The first extension plate 134 is used to connect with the circuit board module 200. Therefore, the first extension plate 134 needs to have a certain distance from the first circuit board 140 to avoid interference between the first extension plate 134 and the first circuit board 140.

[0083] For example, there are two first extension plates 134 and two second extension plates 135. One second extension plate 135, one first extension plate 134, another second extension plate 135 and another first extension plate 134 are sequentially spaced apart on the edge of the bracket body 131 in the X direction.

[0084] Please refer to the following: Figure 5 The first baffle 132 is provided with a first sliding groove 138. The first sliding groove 138 extends through the first baffle 132 along the X direction. The first sliding groove 138 includes a first groove 1381 and a second groove 1382 that are connected. The first groove 1381 and the second groove 1382 are connected along the Y direction. The first groove 1381 has an opening in the opposite direction to the Z direction. The dimension d1 of the second groove 1382 is larger than the cross-sectional dimension of the second connecting post 1211 and smaller than the cross-sectional dimension of the second end 1212. When the second groove 1382 is circular, its dimension d1 can be the diameter of the second groove 1382; or when the second groove 1382 is a non-circular shape, its dimension d1 can be the maximum width of that shape.

[0085] Please refer to the following: Figure 6 The second baffle 133 is provided with a second sliding groove 139, which extends through the second baffle 133 along the X direction. The second sliding groove 139 includes a third groove 1391 and a fourth groove 1392 that are connected to each other. The third groove 1391 and the fourth groove 1392 are arranged sequentially along the Y direction. For example, the third groove 1391 has an opening facing the opposite direction to the Z direction. The size of the fourth groove 1392 is larger than the cross-sectional size of the first connecting post 1132 and smaller than the cross-sectional size of the first end 1133. When the fourth groove 1392 is circular, its size can be the diameter of the fourth groove 1392; or when the fourth groove 1392 is a non-circular shape, its size can be the maximum width of that shape.

[0086] The first extension plate 134 is provided with a module connection hole 1341, which penetrates the first extension plate 134 along the Z direction (thickness direction of the bracket body 131).

[0087] The second extension plate 135 has through holes that extend through the second extension plate 135 along the thickness direction of the bracket body 131. Each screw 136 passes through the through hole of its respective second extension plate 135. It should be noted that the screws 136 can also be captive screws, which will not fall off the module bracket 130 during the assembly of the computing device 1000, making assembly easier for workers. Alternatively, other common connectors can be used instead of screws.

[0088] Multiple module connecting pins 1370 can be spaced apart on the surface of the module bracket 130. Each module connecting pin 1370 includes a connecting post and an end portion. Specifically, each module connecting pin 1370 includes a third connecting post 1371 and a third end portion 1372. The axial direction of the third connecting post 1371 is the Z-direction. The cross-sectional dimension of the third end portion 1372 is larger than that of the third connecting post 1371. This cross-sectional dimension can be the cross-sectional area of ​​the largest cross-section of either the third end portion 1372 or the third connecting post 1371 in a direction perpendicular to the Z-direction. That is, in a direction perpendicular to the axial direction of the third connecting post 1371, the largest cross-section of the third end portion 1372 is larger than the largest cross-section of the third connecting post 1371. The third end portion 1372 is connected to the end of the third connecting post 1371 away from the module bracket 130. For example, there can be six module connecting pins 1370, with three module connecting pins 1370 located on the side of the module bracket 130 facing the opposite direction to the Y-direction, and spaced apart sequentially along the X-direction. One module connecting pin 1370 is located on the side of the module support 130 facing the Y direction. Two module connecting pins 1370 are located at the middle position of the module support 130. In one possible embodiment, there may be one module connecting pin 1370, which may be located at the middle position of the surface of the module support 130 facing the Y direction.

[0089] During the assembly of the module bracket 130 and the housing 110, the first baffle 132 faces the power bracket 120. The second baffle 133 faces the second side plate 113. Specifically, the second end 1212 of the bracket connecting pin 121 is passed through the opening of the first groove 1381 of the first slide groove 138 of the module bracket 130, so that the second connecting post 1211 of the bracket connecting pin 121 is located in the first groove 1381. The first end 1133 of the side plate connecting pin 1131 is passed through the opening of the third groove 1391 of the second slide groove 139, so that the first connecting post 1132 of the side plate connecting pin 1131 is located in the third groove 1391.

[0090] Please see Figure 7 , Figure 7 yes Figure 1 The diagram shows a cross-sectional view of the computing device 1000 along plane AA. The module bracket 130 is moved in the Y direction, causing the second connecting post 1211 of the bracket connecting pin 121 to engage with the wall of the second groove 1382, and the first connecting post 1132 of the side plate connecting pin 1131 to engage with the wall of the fourth groove 1392. The second end 1212 is located on the side of the second groove 1382 facing the X direction. The first end 1133 is located on the side of the fourth groove 1392 facing the opposite X direction. In this way, the module bracket 130 is fixedly mounted to the power supply bracket 120 and the housing 110.

[0091] For example, there may be two first slide grooves 138, which are spaced apart along the Y direction on the first baffle 132. The positions of the two first slide grooves 138 correspond to the positions of the two bracket connecting pins 121. There may also be two second slide grooves 139, which are spaced apart along the Y direction on the second baffle 133. The positions of the two second slide grooves 139 correspond to the positions of the two side plate connecting pins 1131.

[0092] It should be noted that in some implementations of this application, the computing device 1000 may not include the power supply bracket 120. The bracket connecting pin 121 mentioned above can be directly connected to the side of the first side plate 112 facing the second side plate 113. The first sliding groove 138 of the module bracket 130 and the bracket connecting pin 121 mutually limit each other, so that one side of the first baffle 132 of the module bracket 130 is connected to the first side plate 112. The second sliding groove 139 of the module bracket 130 and the side plate connecting pin 1131 mutually limit each other, so that one side of the second baffle 133 of the module bracket 130 is connected to the second side plate 113.

[0093] Please refer to the following: Figure 2 The first circuit board 140 is connected to the module bracket 130 via screws 136 passing through through holes in the second extension plate 135. The first circuit board 140 is located between the module bracket 130 and the base plate 111. The first circuit board 140 can be the motherboard of the computing device 1000, used to provide electrical connection lines for various components in the computing device 1000.

The circuit board module 200 includes a second circuit board 210, a backing plate 220, a movable member 230, and an elastic member (not shown). The second circuit board 210, the backing plate 220, and the movable member 230 are partially stacked in sequence and detachably connected. It should be noted that the second circuit board 210, the backing plate 220, and the movable member 230 are of different sizes, and the stacked arrangement means that the orthographic projections of the second circuit board 210, the backing plate 220, and the movable member 230 in the Z direction at least partially overlap. The second circuit board 210 is fixedly connected to the backing plate 220. The backing plate 220 is connected to the movable member 230, and the movable member 230 is fixedly connected to the module bracket 130, thereby realizing the installation and fixation of the circuit board module 200 and the module bracket 130. Part of the structure of the movable member 230 may protrude relative to the periphery of the backing plate 220 and / or the second circuit board 210, which will be described in detail below.

[0095] Please see Figure 10 , Figure 10 yes Figure 8 The diagram shows a structural schematic of the liner 220 at one angle. The liner 220 includes a plate body 221, one or more first supporting parts 222, and one or more connecting parts 223. The first supporting parts 222 and the connecting parts 223 are disposed on the plate body 221.

[0096] The plate 221 includes a liner body 2211 and a third extension plate 2212.

[0097] Specifically, the liner body 2211 includes a first side 2214 and a second side 2215 disposed opposite to each other along its width direction. A third extension plate 2212 is connected to the first side 2214, and the end of the third extension plate 2212 away from the liner body 2211 is bent and extended away from the liner body 2211. Specifically, the third extension plate 2212 includes a first portion 2212a and a second portion 2212b. One side of the first portion 2212a is connected to the edge of the liner body 2211, and the first portion 2212a is set at an angle to the surface of the liner body 2211 facing the Z direction, and the angle can be 90°. The side of the first portion 2212a away from the liner body 2211 is bent and connected to the second portion 2212b, and the second portion 2212b extends from the edge of the first portion 2212a in a direction away from the liner body 2211. Figure 10 (Extends in the opposite direction of the Y direction shown).

[0098] The liner body 2211 may have a plurality of first receiving holes 2213 and a plurality of connecting through holes 2216. The first receiving holes 2213 are located on the first side 2214 of the liner body 2211. The plurality of first receiving holes 2213 are spaced apart along the length direction of the liner body 2211. The first receiving holes 2213 penetrate the liner body 2211 along the thickness direction. In one possible embodiment, there may be only one first receiving hole 2213, and the first receiving hole 2213 may be located at the middle position of the first side 2214 of the liner body 2211.

[0099] Multiple connecting through holes 2216 are spaced apart on the liner body 2211 and penetrate the liner body 2211 along its thickness direction. For example, there may be nine connecting through holes 2216. Specifically, three connecting through holes 2216 are located at one end of the liner body 2211 facing the opposite direction to the Y direction and are spaced apart along the X direction. Alternatively, three connecting through holes 2216 may be located at one end of the liner body 2211 facing the Y direction and are arranged sequentially along the X direction. Or, three connecting through holes 2216 may be located at the center of the liner body 2211. In one possible implementation, there may be only one connecting through hole 2216, which may be located at the center of the liner body 2211.

[0100] A first abutment portion 222 is connected to a first receiving hole 2213. The first abutment portion 222 can be fixedly connected to the hole wall of the first receiving hole 2213. Specifically, the first abutment portion 222 includes a first abutment surface 2222 and a second abutment surface 2223 disposed opposite to each other along the Y direction. The first abutment surface 2222 faces the Y direction, and the second abutment surface 2223 faces the opposite direction of the Y direction. The first abutment portion 222 can be connected to the hole wall of the first receiving hole 2213 near the first side 2214 and extends along the thickness direction of the liner body 2211. A protruding first positioning post 2221 is provided on the surface of the first abutment portion 222 facing the second side 2215. The first positioning post 2221 extends from the surface of the first abutment portion 222 in the direction toward the second side 2215.

[0101] A connector 223 passes through a connecting through-hole 2216 and is fixedly connected to the connecting through-hole 2216. For example, the connector 223 can be a stepped rivet. The connector 223 includes a first segment 2231, a second segment 2232, and a third segment 2233 arranged sequentially along its length. The cross-sectional dimension of the first segment 2231 is smaller than that of the second segment 2232. The cross-sectional dimension of the second segment 2232 can be smaller than that of the third segment 2233. The first segment 2231 of the connector 223 can be fixedly connected to the connecting through-hole 2216. The aforementioned cross-sectional dimension can be the cross-sectional area of ​​the largest cross-section of the first segment 2231, the second segment 2232, or the third segment 2233 in a direction perpendicular to the Z-direction. That is, in a direction perpendicular to the stacking direction of the first segment 2231, the second segment 2232, and the third segment 2233, the largest cross-sectional dimension of the first segment 2231 is smaller than that of the second segment 2232. The cross-sectional dimensions of the second segment 2232 can be smaller than the maximum cross-sectional dimensions of the third segment.

[0102] Please see Figure 11 , Figure 11 yes Figure 8The diagram shows a structural schematic of the liner 220 from a bottom view. The liner 220 may also include multiple protrusions 2201, which are located on the surface of the liner body 2211 facing the opposite direction to the Z-direction. The protrusions 2201 of the multiple liner 220 are spaced apart on the liner body 2211. Each protrusion 2201 has a connecting through hole 2216. The connecting through hole 2216 penetrates the protrusion 2201 and the liner body 2211 along the Z-direction.

[0103] Please refer to the following: Figure 12 and Figure 13 , Figure 12 yes Figure 8 The diagram shows a structural schematic of the movable part 230 at one angle, wherein... Figure 12 The angle of the illustration is close to that of looking up from below. Figure 13 yes Figure 8 The diagram shows a top-view view of the movable component 230. The movable component 230 includes a movable component body 231, one or more second abutment portions 232, and one or more fourth extension plates 233. The second abutment portions 232 protrude from the surface of the movable component body 231. The fourth extension plates 233 are connected to the edges of the movable component body 231.

[0104] The movable body 231 includes a third side 2311 and a fourth side 2312 disposed opposite to each other in its width direction, and a first surface 2313 and a second surface 2314 disposed opposite to each other in its thickness direction.

[0105] The movable part body 231 is provided with one or more second receiving holes 235, one or more second connecting portions 236, and one or more connecting grooves 237. The second connecting portion 236 can be a sliding groove 2360, or it can be the module connecting pin 1370 described above. When the second connecting portion 236 is a module connecting pin 1370, the first connecting portion 137 can be the sliding groove 2360 described below. The following description uses the second connecting portion 236 as a sliding groove 2360. However, it should be understood that the embodiments of this application include all mating methods where one of the first connecting portion 137 and the second connecting portion 236 is a sliding groove 2360, and the other is a module connecting pin 1370. In one possible implementation, a plurality of second receiving holes 235 are arranged at intervals on the third side 2311. A plurality of sliding grooves 2360 are evenly distributed on the movable part body 231. A plurality of connecting grooves 237 are evenly distributed on the movable part body 231. Furthermore, the second receiving hole 235, the sliding groove 2360, and the connecting groove 237 are all spaced apart. In another possible embodiment, the movable body 231 may be provided with a second receiving hole 235, a second connecting portion 236, and / or a connecting groove 237. This application does not limit the number of the second receiving hole 235, the second connecting portion 236, and the connecting groove 237. It should be noted that the number of the second receiving hole 235 may be the same as the number of the first receiving hole 2213, the number of the second connecting portion 236 may be the same as the number of the first connecting portion 137, and the number of the connecting groove 237 may be the same as the number of the connecting member 223.

[0106] The second receiving hole 235 penetrates the first surface 2313 and the second surface 2314 along the thickness direction of the movable member 230. Furthermore, a plurality of second receiving holes 235 are arranged at intervals along the length direction of the movable member body 231 on the third side 2311. In this embodiment, the second receiving hole 235 is strip-shaped.

[0107] Multiple grooves 2360 are evenly distributed at intervals on the movable body 231. The grooves 2360 penetrate the first surface 2313 and the second surface 2314 of the movable body 231 along its thickness direction. Each groove 2360 includes a first annular groove 2361 and a second annular groove 2362 that are connected. The first annular groove 2361 and the second annular groove 2362 are sequentially arranged along the width direction of the movable body 231. For example, the size of the first annular groove 2361 is larger than the size of the second annular groove 2362. Furthermore, the size of the first annular groove 2361 is larger than the cross-sectional size of the third end 1372. The size of the second annular groove 2362 is larger than the cross-sectional size of the third connecting post 1371 and smaller than the cross-sectional size of the third end 1372. The sizes of the first annular groove 2361 and the second annular groove 2362 can be their diameters.

[0108] Multiple connecting slots 237 are spaced apart on the movable part body 231, and the connecting slots 237 penetrate the first surface 2313 and the second surface 2314 of the movable part body 231 along the thickness direction of the movable part body 231. The connecting slots 237 are elongated, and the length direction of the connecting slots 237 is the width direction of the movable part 230. For example, there can be nine connecting slots 237. Among them, three connecting slots 237 are located on the third side 2311 of the movable part body 231 and are arranged at intervals along the length direction of the movable part 230. Three connecting slots 237 are located on the fourth side 2312 of the movable part body 231 and are arranged sequentially along the length direction of the movable part 230. Three connecting slots 237 are located at the middle position of the movable part body 231 and are arranged sequentially along the length direction of the movable part 230.

[0109] The second abutment portion 232 protrudes from the second surface 2314 and is connected to the side wall of the second receiving hole 235 facing the fourth side 2312. The second abutment portion 232 is provided with a second positioning post 2321. The second positioning post 2321 protrudes from the surface of the second abutment portion 232 facing away from the fourth side 2312 and extends toward the third side 2311.

[0110] Multiple fourth extension plates 233 are connected to the edge of the fourth side 2312 of the movable body 231. The fourth extension plate 233 extends from the edge of the movable body 231 along the width direction of the movable member 230. For example, the fourth extension plate 233 can be formed by bending and extending the edge of the movable body 231, and the fourth extension plate 233 can be L-shaped. Each fourth extension plate 233 has a fixing hole 2331. The fixing hole 2331 penetrates the fourth extension plate 233 along the thickness direction of the movable member 230. For example, there can be two fourth extension plates 233, therefore there can be two fixing holes 2331, and the two fourth extension plates 233 are spaced apart along the length direction of the movable member 230.

[0111] The computing device 1000 also includes one or more fasteners 234. One fastener 234 is connected to a fourth extension plate 233. The fastener 234 can pass through a fixing hole 2331. The fastener 234 is used to connect with the module connection hole 1341 of the module bracket 130. Specifically, the first connecting portion 137 and the second connecting portion 236 have a locked state and an unlocked state. When the first connecting portion 137 and the second connecting portion 236 are in the locked state, the fastener 234 is fixedly connected to the hole wall of the module connection hole 1341, so that the movable member 230 is connected to the module bracket 130. When the first connecting portion 137 and the second connecting portion 236 are in the unlocked state, the fastener 234 is disengaged from the module connection hole 1341. The fastener 234 can be Figure 12The screw shown is a captive screw. It should be noted that setting a captive screw in the fixing hole 2331 can simplify the assembly process of the computing device 1000 and prevent the captive screw from falling out of the fixing hole 2331.

[0112] It should be noted that after the movable part 230, the liner 220, and the second circuit board 210 are assembled, the fourth extension plate 233 can protrude relative to the second circuit board 210 and the liner 220 in the width direction of the circuit board module 200. Since the fourth extension plate 233 is not covered or blocked by the second circuit board 210 and the liner 220, the fastener 234 connected to the fourth extension plate 233 has operable space when connected to the structure on the module bracket 130.

[0113] The movable component 230 may also include a raised rib portion (not shown in the figure). The raised rib portion is used to oppose the protrusion 2201 portion of the liner 220. The raised rib portion is provided on the first surface 2313 of the movable component body 231 and divides the first surface 2313 of the movable component body 231 into four regions. The raised rib portion may include a first raised rib 2301, a second raised rib 2302, a third raised rib 2303, a fourth raised rib 2304, and a fifth raised rib 2305. The first raised rib 2301, the second raised rib 2302, and the third raised rib 2303 are arranged alternately along the X direction and extend along the Y direction. The fourth raised rib 2304 and the fifth raised rib 2305 are arranged alternately along the Y direction and extend along the X direction. The fourth raised rib 2304 and the fifth raised rib 2305 intersect with the first raised rib 2301, the second raised rib 2302, and the third raised rib 2303. The second surface 2314 of the movable part body 231 may be recessed at the corresponding location of the protruding rib portion. The connecting groove 237 described above may also be located on the protruding rib portion, and the connecting groove 237 penetrates the protruding rib portion and the movable part body 231 along the Z direction. For example, there may be nine connecting grooves 237. Three connecting grooves 237 are spaced apart along the Y direction on the first protruding rib 2301. Three connecting grooves 237 are spaced apart along the Y direction on the second protruding rib 2302. Three connecting grooves 237 are spaced apart along the Y direction on the third protruding rib 2303. For example, the connecting groove 237 may also be located at the connection point between the fifth protruding rib 2305 and the first protruding rib 2301, the second protruding rib 2302, and the third protruding rib 2303.

[0114] Please see Figure 14 , Figure 14 This is a partial schematic diagram showing the engagement of the movable part 230 and the liner 220. The second abutting part 232 is disposed opposite to the first abutting part 222 of the liner 220. Specifically, the second abutting part 232 is disposed opposite to the first abutting surface 2222 of the first abutting part 2222. The first positioning post 2221 and the second positioning post 2321 are spaced apart and disposed opposite to each other. Please refer to the attached diagram. Figure 14 and Figure 15 , Figure 15 This is a partial schematic diagram showing the engagement of the movable member 230 with a liner 220 and an elastic member 240. One end of the elastic member 240 is connected to the first abutment portion 222 of the liner 220, and the other end of the elastic member 240 is connected to the second abutment portion 232 of the movable member body 231. For example, the elastic member 240 can be a spring, with one end of the spring sleeved on the first positioning post 2221 and the other end of the spring sleeved on the second positioning post 2321.

[0115] Please refer to the following: Figure 8 , Figure 10 and Figure 12 Multiple connecting slots 237 are positioned corresponding to multiple connecting members 223. Connecting members 223 pass through the connecting slots 237 of the movable body 231 and the connecting through holes 2216 of the liner 220. Connecting members 223 can slide within the connecting slots 237. The first segment 2231 of the connecting member 223 passes through the connecting slots 237 and the connecting through holes 2216 sequentially and is fixedly connected to the liner 220. The second segment 2232 passes through the connecting slots 237. The third segment 2233 is located on the side of the movable body 230 away from the liner 220, and can abut against the surface of the movable body 230 away from the liner 220. The third segment 2233 can limit the movement of the movable body 231, preventing the movable body 231 from detaching from the liner 220 in the Z direction. For example, the cross-sectional dimension of the second segment 2232 can be smaller than the width of the connecting groove 237 in the X direction, so that the connector 223 will not have excessive friction when sliding in the connecting groove 237.

[0116] Understandably, the first segment 2231 of the connector 223, due to its small cross-sectional size, can easily pass through the connecting groove 237 and the connecting through hole 2216. The second segment 2232 can be spaced from the groove wall of the connecting groove 237, so that when the connector 223 slides relative to the connecting groove 237, it will not generate a large frictional force with the groove wall of the connecting groove 237, ensuring that the movable part 230 can slide relatively smoothly with the liner 220. The third segment 2233 can abut against the surface of the movable part 230 away from the liner 220, thereby preventing the movable part 230 from separating from the liner 220 in the Z direction.

[0117] In one possible implementation, when the movable part 230 has a raised strip portion and the liner 220 has a protrusion 2201, the raised strip portion can be arranged opposite to the protrusion 2201. The connector 223 can pass through the connecting groove 237 on the raised strip portion and the connecting through hole 2216 on the protrusion 2201 in sequence and then connect to the liner body 2211.

[0118] It is understandable that the protrusion and the protrusion 2201 can reduce the distance between the movable part 230 and the backing plate 220. The protrusion can abut against the protrusion 2201, thereby making the relative position of the movable part 230 and the backing plate 220 more stable, and thus improving the overall structural strength of the circuit board module 200.

[0119] Please refer to the following: Figure 6 , Figure 12 and Figure 16 , Figure 16 yes Figure 12 The diagram shows the structure of the movable part 230 after assembly with the module bracket 130. The third end 1372 of the module connecting pin 1370 of the module bracket 130 passes through the slide groove 2360. Specifically, during the actual assembly process, the third end 1372 passes through the first annular groove 2361 of the slide groove 2360, and then the movable part body 231 is slid in the Y direction, so that the third connecting pin 1371 slides into the second annular groove 2362, and the second annular groove 2362 can limit the third connecting pin 1371. At this time, the spring is compressed, and the fixing part 234 is aligned with the module connecting hole 1341 of the module bracket 130. Rotating the fixing part 234 screws the fixing part 234 into the module connecting hole 1341, thereby fixing the circuit board module 200 to the module bracket 130.

[0120] It is understood that the first connecting part 137 and the second connecting part 236 have locked and unlocked states. When the first connecting part 137 and the second connecting part 236 are in the unlocked state, the circuit board module 200 is not fixedly connected to the module support 130, and the elastic element 240 of the circuit board module 200 is in its initial state. At this time, the first connecting part 137 and the second connecting part 236 are in the second position, and the elastic element 240 is not compressed or compressed by a very small distance; the length of the elastic element is the first length. When the first connecting part 137 and the second connecting part 236 are in the locked state, the first connecting part 137 and the second connecting part 236 are in the first position. Specifically, the slide groove 2360 of the movable part body 231 aligns with the module connecting pin 1370 of the module support 130, and the third end 1372 is inserted into the first annular groove 2361 of the slide groove 2360. Simultaneously, the second circuit board 210 and the first circuit board 140 can be plugged in. Then, the movable member 230 moves in the Y direction. At this time, the movable member 230 moves relative to the liner 220, thereby compressing the elastic member 240 located between the first abutment 222 and the second abutment 232, so that the elastic member 240 is in a compressed state. At this time, the length of the elastic member is the second length, which is less than the first length. At the same time, the third connecting post 1371 of the module connecting pin 1370 moves from the first annular groove 2361 to the second annular groove 2362, and the third end 1372 is located at the end of the second annular groove 2362 facing the Z direction, so that the module connecting pin 1370 can limit the movable member 230. The fixing member 234 located in the fixing hole 2331 of the movable member body 231 is fixedly connected to the module connecting hole 1341 of the module bracket 130. At this time, the circuit board module 200 and the module bracket 130 are connected.

[0121] The computing device 1000 provided in this embodiment can move the movable part 230 back and forth to achieve rapid installation and removal of the circuit board module 200. Furthermore, when the circuit board module 200 is used as an independent replacement unit, it can be maintained separately, thereby reducing maintenance costs, saving maintenance time, and simplifying the maintenance process.

[0122] When the circuit board module 200 disengages from the module bracket 130, the elastic element 240 can undergo elastic deformation and automatically return from the compressed state to its initial state. This ensures that when the circuit board module 200 is connected to the module bracket 130 again, the movable element 230 and the liner 220 can move relative to each other, allowing for direct connection with the module bracket. Specifically, when the elastic element of the circuit board module 200 returns from the compressed state to its initial state, the first annular groove 2361 corresponds to the position of the module connecting pin 1370, and the electrical connection position of the first circuit board 140 corresponds to the electrical connection position of the second circuit board 210, so that the circuit board module 200 can be directly stacked and installed with the module bracket 130.

[0123] The computing device 1000 provided in this application embodiment can complete the connection between the circuit board module 200 and the module bracket 130 by aligning the circuit board module 200 and the module bracket 130 and moving the movable part 230 in the circuit board module 200 a certain distance. This avoids the use of a large number of screws and nuts for connection, reduces the connection difficulty between the circuit board module 200 and the module bracket 130, saves the assembly cost of the computing device 1000, and reduces the connection time of the circuit board module 200 and the module bracket 130.

[0124] Please refer to [link / reference needed] for further information. Figure 17 , Figure 17 This is a partial schematic diagram showing the engagement of the movable member 230 with another liner 220 and the elastic member 240. In one possible embodiment, the first abutment portion 222 may also be connected to the hole wall of the first receiving hole 2213 opposite to the first side 2214 and extend along the thickness direction of the liner body 2211. The second abutment portion 232 protrudes from the second surface 2314 and is connected to the side hole wall of the second receiving hole 235 facing the fourth side 2312. The second abutment portion 232 is disposed opposite to the first abutment portion 222. Specifically, the second abutment portion 232 is disposed opposite to the second abutment surface 2223 of the first abutment portion 222. The elastic member 240 is disposed between the first abutment portion 222 and the second abutment portion 232. In this case, the elastic member 240 may be a tension spring.

[0125] In this embodiment, the first connecting part 137 and the second connecting part 236 are in the unlocked state, the circuit board module 200 and the module bracket 130 are not fixedly connected, and the elastic member 240 of the circuit board module 200 is in the initial state. At this time, the first connecting part 137 and the second connecting part 236 are in the second position, and the elastic member 240 is not stretched or stretched to a small extent. At this time, the length of the elastic member 240 is the third length. The first connecting part 137 and the second connecting part 236 are in the locked state, and the first connecting part 137 and the second connecting part 236 are in the first position. Specifically, the slide groove 2360 of the movable part body 231 is aligned with the module connecting pin 1370 of the module bracket 130, and the third end 1372 is inserted into the first annular groove 2361 of the slide groove 2360. At the same time, the second circuit board 210 and the first circuit board 140 can be plugged in. Then, the movable member 230 moves in the Y direction. At this time, the movable member 230 moves relative to the liner 220, thereby stretching the elastic member 240 located between the first abutment 222 and the second abutment 232, so that the elastic member 240 is in a stretched state. At this time, the length of the elastic member 240 is the fourth length, which is greater than the third length. At the same time, the third connecting post 1371 of the module connecting pin 1370 moves from the first annular groove 2361 to the second annular groove 2362, and the third end 1372 is located at the end of the second annular groove 2362 facing the Z direction, so that the module connecting pin 1370 can limit the movable member 230. The fixing member 234 located in the fixing hole 2331 of the movable member body 231 is fixedly connected to the module connecting hole 1341 of the module bracket 130. At this time, the circuit board module 200 and the module bracket 130 are connected.

[0126] When the circuit board module 200 disengages from the module bracket 130, the elastic element 240 can undergo elastic deformation and automatically return from the stretched state to its initial state. This ensures that when the circuit board module 200 is connected to the module bracket 130 again, the movable element 230 and the liner 220 can move relative to each other, allowing for direct connection with the module bracket 130. Specifically, after the elastic element of the circuit board module 200 returns to its initial state, the first annular groove 2361 can correspond to the position of the module connecting pin 1370, and the electrical connection position of the first circuit board 140 can correspond to the electrical connection position of the second circuit board 210, so that the circuit board module 200 can be directly stacked and installed with the module bracket.
