[0002] The chassis of electronic equipment is often equipped with network cards, service cards, memory cards, graphics processing units (GPUs), data processing units (DPUs) and other boards, and the boards need to be electrically connected to the mainboard of the electronic equipment. In order to save installation space on the mainboard, a riser card assembly can be provided in the chassis of the electronic equipment. The riser card assembly can include a riser card and a bracket. The riser card is fixedly arranged on the bracket, and the bracket is fixedly connected to the chassis. The riser card has a connector electrically connected to the mainboard, and the board is plugged into the connector on the riser card to be electrically connected to the mainboard through the connector on the riser card. The board is also fixedly connected to a handle bar, and the handle bar is used to be fixedly connected to the bracket.

[0003] The riser card assembly has various sizes such as full height and half height. In the related art, it is often necessary to adapt the handle bar according to the size of the riser card assembly. For example, a full-height riser card assembly needs to use a handle bar of the corresponding full-height size to be fixedly connected to the bracket, and a half-height riser card assembly needs to use a handle bar of the corresponding half-height size to be fixedly connected to the bracket. In the related art, the universality of the handle bar is poor.

[0004] Therefore, how to improve the versatility of the handle bar has become an urgent problem to be solved in the field of electronic equipment technology. Utility Model Content

[0005] The embodiments of the present application provide a handle bar, a board assembly and an electronic device. The size of the handle bar in the length direction is adjustable, and the handle bar has good versatility.

[0006] In a first aspect of an embodiment of the present application, there is provided a handle bar, comprising a first connecting member and a second connecting member. The first connecting member comprises a first end and a second end, the first end and the second end are respectively located at two ends of the first connecting member in a first direction, the first end has a first connecting structure, and the second connecting member is retractably connected to the second end. The second connecting member has a second connecting structure, and the second connecting member can be retracted along the first direction relative to the first connecting member to change the spacing between the first connecting structure and the second connecting structure. The first direction is the length direction of the first connecting member, the first connecting member is used to be fixedly connected to the board, and the first connecting structure and the second connecting structure are used to be connected to the adapter card assembly.

[0007] The handle bar provided in the embodiment of the present application can adjust the size of the handle bar in the length direction of the first connecting member by extending and retracting the second connecting member, so that the spacing between the first connecting structure and the second connecting structure changes, so that the handle bar can be fixedly connected to adapter card assemblies of different sizes, and the same handle bar can be applicable to adapter card assemblies of multiple different sizes, so that the handle bar has better versatility. When the board and card assembly is replaced in the use scenario of adapter card assemblies of different sizes, there is no need to replace the handle bar of the board and card assembly, so that the board and card assembly is easier to replace in the use scenario of adapter card assemblies of different sizes. In addition, the number of times the handle bar and the board and card are disassembled and assembled can be reduced, and the risk of the board and card being scratched can be reduced. In addition, the number of handle bars that need to be configured for the board and card assembly can be reduced, thereby reducing the workload of storing and managing accessories of the electronic device.

[0008] In a possible implementation, the first connecting member is slidably connected to the second connecting member, and the second connecting member can slide along a first direction relative to the first connecting member.

[0009] In this way, the distance between the first connection structure and the second connection structure can be changed by relative sliding of the first connection member and the second connection member, the second connection member has better stability when extending and retracting along the first direction, and the first connection member and the second connection member are not prone to bending, which is conducive to the fixation of the handle bar and the adapter card assembly. In addition, the structure of the handle bar can also be made simpler.

[0010] In a possible implementation, the first connecting member includes a first side edge, the first side edge is located at one side of the first connecting member in the second direction, and a slideway structure is provided at the first side edge. The second connecting member includes a second side edge, the second side edge is located at one side of the second connecting member in the second direction, and a sliding connection structure is provided at the second side edge. The first connecting member and the second connecting member are slidably connected via the slideway structure and the sliding connection structure. The second direction is the width direction of the first connecting member, and the first direction is perpendicular to the second direction.

[0011] In this way, the slide structure and the sliding connection structure are respectively located on the sides of the first connecting member and the second connecting member. The set slide structure and the sliding connection structure are not easy to interfere with the arrangement of other components, which facilitates the assembly between the board and the handle bar.

[0012] In a possible embodiment, the first connecting member further includes a third side, and the first side and the third side are respectively located on both sides of the first connecting member in the second direction. The slideway structure includes a first folding structure, a second folding structure and a third folding structure, one side of the first folding structure is connected to the first side, the first folding structure extends along the third direction, the other side of the first folding structure is connected to one side of the second folding structure, the second folding structure extends along the second direction toward the direction close to the third side, the other side of the second folding structure is connected to one side of the third folding structure, the third folding structure extends along the third direction toward the direction close to the first connecting member, and there is a gap between the other side of the third folding structure and the first connecting member, and the first folding structure, the second folding structure and the third folding structure are surrounded to form a slideway. The second connecting member is arranged in the gap between the third folding structure and the first connecting member. The sliding connection structure includes a fourth folding structure, one side of the fourth folding structure is connected to the second side, the fourth folding structure extends along a third direction, the fourth folding structure is inserted in the slide groove, the fourth folding structure and the slide groove are slidably matched, and the fourth folding structure can slide relative to the slide groove along the first direction. The third direction is the thickness direction of the first connecting member, the third direction is perpendicular to the first direction, and the third direction is perpendicular to the second direction.

[0013] In this way, it is easier to form the slideway structure and the sliding connection structure, and the first connection member of the slideway structure and the second connection member of the sliding connection structure are simpler in structure and smaller in size.

[0014] In a possible embodiment, the first connector has a connector installation opening, and the connector installation opening passes through the first connector along the third direction. The second connector also includes a third end, a fourth end, and a fourth side, the third end and the fourth end are respectively located at the two ends of the second connector in the first direction, and the second side and the fourth side are respectively located at the two sides of the second connector in the second direction. In the first direction, the third end is located between the first end and the second end, and the second end is located between the first end and the fourth end. The third end has an avoidance gap, and the avoidance gap is an open structure on the side away from the second side, and the avoidance gap is used to avoid the connector installation opening so that the connector installation opening is located outside the sliding path of the second connector.

[0015] In this way, the third connector inserted into the connector installation opening will not block the sliding of the second connecting member, thereby facilitating the extension and retraction of the second connecting member.

[0016] In a possible implementation manner, the fourth end has a second connection structure.

[0017] In this way, the overall length of the handle bar can be made shorter, the handle bar is not likely to interfere with other components of the electronic device, and the arrangement of the handle bar is facilitated.

[0018] In a possible embodiment, the handle strip also includes a foldable shielding member. The shielding member includes a fifth end and a sixth end, and the fifth end and the sixth end are respectively located at the two ends of the shielding member in the first direction, the fifth end is fixedly connected to the first connecting member, and the sixth end is fixedly connected to the second connecting member. In the first direction, the connector mounting port is located between the fifth end and the first end, and the sixth end is located between the avoidance gap and the fourth end. The second connecting member sliding along the first direction toward the direction close to the first end is used to fold the shielding member, and the second connecting member sliding along the first direction toward the direction away from the first end is used to unfold the shielding member. When the end of the avoidance gap close to the fourth end is located between the second end and the fourth end, the avoidance gap includes a hollow portion between the end of the avoidance gap close to the fourth end and the second end, and the shielding member is used to shield the hollow portion.

[0019] In this way, the shielding piece can block the debris that enters the side of the board where the handle bar is set through the hollow part, thereby reducing the impact of the debris on the operation of the board.

[0020] In a possible implementation manner, a fixing plate is provided on the third side of the first connecting member, the fixing plate protrudes from the first connecting member along the third direction, and the first connecting member is used to be fixedly connected to the board through the fixing plate.

[0021] In this way, the board can be used to contact the fixing plate with a larger area, which can make the board and the first connecting member connected more firmly. In addition, the fixing plate protruding from the first connecting member can also make it easier to fix the board and the first connecting member. In addition, the board can be fixedly connected to the side of the first connecting member away from the slide structure through the fixing plate, which can make a larger gap between the board and the slide structure, which is conducive to the second connecting member slidably connected to the first connecting member to avoid the board.

[0022] In a possible implementation, the first connection structure is a plug-in structure, which is used to be plugged into a plug interface of the adapter card assembly. The second connection structure is a fixed connection structure, which is used to be detachably connected to the adapter card assembly.

[0023] In this way, the handle bar and the adapter card assembly can be easily disassembled and assembled.

[0067] The board assembly 40 may include a board 400, the board 400 is plugged into the riser assembly 30 and electrically connected to the riser assembly 30, and the board 400 is electrically connected to the mainboard 20 via the riser assembly 30. Specifically, the riser 100 has a second connector 110, the board 400 is plugged into the second connector 110, and the board 400 is electrically connected to the riser 100 via the second connector 110.

[0068] Exemplarily, the second connector 110 may be a peripheral component interconnect express (PCIE) connector, and the board 400 may be a PCIE card.

[0069] Exemplarily, the board 400 may include, but is not limited to, a network card, a service card, a storage card, a graphics processing unit (GPU), a data processing unit (DPU), a redundant array of independent disks (RAID) card, etc. For example, the board 400 may be a fiber channel (FC) network card, a network interface card (NIC), or an infinite bandwidth (IB) network card, etc.

[0070] Exemplarily, the board card 400 may include a gold finger connector (not shown), and the board card 400 is plugged into the second connector 110 via the gold finger connector. The board card 400 is electrically connected to the adapter card 100 via the gold finger connector and the second connector 110 .

[0071] The board and card assembly 40 also includes a handle bar 300, and the board and card 400 is fixedly connected to the handle bar 300. The two ends of the handle bar 300 in the length direction are respectively provided with a first connection structure 313 and a second connection structure 323, and the first connection structure 313 and the second connection structure 323 are both connected to the adapter card assembly 30, so that the handle bar 300 is fixedly connected to the adapter card assembly 30. Specifically, the first connection structure 313 and the second connection structure 323 are both connected to the bracket 200, so that the handle bar 300 is fixedly connected to the bracket 200.

[0072] Exemplarily, the bracket 200 includes a first support member 210 and a second support member 220, one end of the first support member 210 is fixedly connected to one end of the second support member 220, the first support member 210 and the second support member 220 are vertically arranged, the adapter card 100 is fixedly arranged on the first support member 210, the adapter card 100 and the second support member 220 are located on the same side of the first support member 210, and a second connector 110 is provided on the side of the adapter card 100 away from the first support member 210, the board 400 is plugged into the side of the adapter card 100 away from the first support member 210 through the second connector 110, one end of the handle bar 300 in the length direction is connected to the first support member 210 through the first connecting structure 313, and the other end of the handle bar 300 in the length direction is connected to the second support member 220 through the second connecting structure 323.

[0073] Exemplarily, the first support member 210 may be detachably connected to the main board 20 via a fastener.

[0074] To adapt to chassis 10 of different sizes, the riser card assembly 30 has multiple sizes such as full height and half height.

For example, a full-height riser card assembly needs to use a handle bar of the corresponding full-height size to be fixedly connected to the bracket, and a half-height riser card assembly needs to use a handle bar of the corresponding half-height size to be fixedly connected to the bracket.

[0075] In the related art, the versatility of the handle bar is poor. When the board assembly is replaced in the use scenario of the adapter card assembly of different sizes, the handle bar of the board assembly needs to be replaced, which makes it cumbersome to replace the board assembly in the use scenario of the adapter card assembly of different sizes. In addition, in the process of disassembling and assembling the handle bar, the disassembly and assembly tools are prone to scratching the board. In addition, in order to adapt to adapter card assemblies of different sizes, the board assembly often needs to be configured with a variety of handle bars of different sizes. The handle bar that is not assembled on the board needs to be stored and managed separately, which increases the workload of storing and managing accessories of electronic equipment.

[0076] Figure 2 A schematic diagram of a handle bar of a board and card assembly provided in an embodiment of the present application when it is retracted. Figure 3 for Figure 2 A schematic diagram of the handle bar of the board and card assembly when it is extended is provided in . Among them, the x direction is the first direction, the y direction is the second direction, the z direction is the third direction, the first direction is the length direction of the first connecting member 310, the second direction is the width direction of the first connecting member 310, and the third direction is the thickness direction of the first connecting member 310. The first direction is perpendicular to the second direction, the first direction is perpendicular to the third direction, and the second direction is perpendicular to the third direction.

[0077] like Figure 2 , Figure 3As shown, and see Figure 1 Based on this, in the embodiment of the present application, the handle bar 300 includes a first connecting member 310 , and the first connection is fixedly connected to the board 400 .

[0078] Exemplarily, the first connector 310 may be fixedly connected to the board 400 by welding, clamping, bonding, fastener connection, etc.

[0079] The first connector 310 includes a first end 311 and a second end 312, which are respectively located at two ends of the first connector 310 in the first direction, and the first end 311 has a first connection structure 313, which is connected to the riser card assembly 30. Specifically, the first connection structure 313 is connected to the bracket 200.

[0080] The gold finger connector and the first connection structure 313 are located on the same side of the board assembly 40 in the first direction, that is, the orientation of the gold finger connector is the same as that of the first end 311 , and the first connection structure 313 is connected to the first support member 210 .

[0081] Exemplarily, the first connection structure 313 may be connected to the first support member 210 by plugging, snapping, fastener connection, bonding, pressing and fixing, etc.

[0082] The handle bar 300 further includes a second connecting member 320, which is retractably connected to the second end 312, and has a second connecting structure 323. The second connecting member 320 can be retracted along a first direction relative to the first connecting member 310 to change the spacing between the first connecting structure 313 and the second connecting structure 323, and the second connecting structure 323 is connected to the adapter card assembly 30. Specifically, the second connecting structure 323 is connected to the bracket 200.

[0083] The gold finger connector and the second connection structure 323 are located on different sides of the board assembly 40 in the first direction, that is, the orientation of the gold finger connector is different from that of the second end 312 , and the second connection structure 323 is connected to the second support member 220 .

[0084] Exemplarily, the second connecting member 320 may be connected to the second supporting member 220 by means of snap connection, fastener connection, bonding, compression fixation, etc.

[0085] In this way, the size of the handle bar 300 in the length direction of the first connecting member 310 can be adjusted by extending the second connecting member 320, so that the spacing between the first connecting structure 313 and the second connecting structure 323 changes, so that the handle bar 300 can be fixedly connected to the adapter card assembly 30 of different sizes, and the same handle bar 300 can be applied to a variety of adapter card assemblies 30 of different sizes, so that the versatility of the handle bar 300 is better. When the board and card assembly 40 is replaced in the use scene of the adapter card assembly 30 of different sizes, it is not necessary to replace the handle bar 300 of the board and card assembly 40, so that the board and card assembly 40 is easier to replace in the use scene of the adapter card assembly 30 of different sizes. In addition, the number of times the handle bar 300 and the board and card 400 are disassembled and assembled can be reduced, and the risk of the board and card 400 being scratched can be reduced. In addition, the number of handle bars 300 that need to be configured for the board and card assembly 40 can be reduced, thereby reducing the workload of storing and managing accessories of the electronic device.

[0086] The length direction of the first connector 310 is the same as that of the handle bar 300 , the width direction of the first connector 310 is the same as that of the handle bar 300 , and the thickness direction of the first connector 310 is the same as that of the handle bar 300 .

[0087] The second connecting member 320 includes a third end 321 and a fourth end 322, and the third end 321 and the fourth end 322 are respectively located at two ends of the second connecting member 320 in the first direction. In the first direction, the third end 321 and the fourth end 322 are both located on the same side of the first end 311, and the distance between the third end 321 and the first end 311 is smaller than the distance between the fourth end 322 and the first end 311.

[0088] Exemplarily, the first connecting member 310 may be a plate-shaped structure.

[0089] Exemplarily, the second connecting member 320 may be a plate-shaped structure.

[0090] In some examples, the fourth end 322 has a second connection structure 323 .

[0091] In this way, the overall length of the handle bar 300 can be shortened, and the handle bar 300 is less likely to interfere with other components of the electronic device, which facilitates the arrangement of the handle bar 300.

[0092] In some possible implementations, the first connection structure 313 is a plug-in structure, which is plugged into the plug-in interface (not shown) of the adapter card assembly 30. Specifically, when the gold finger connector is inserted into the second connector 110 along the first direction, the plug-in structure can be inserted into the plug-in interface of the adapter card assembly 30 along the first direction, and the plug-in interface can play a positioning role, which can be used to limit the movement of the handle bar 300 relative to the adapter card assembly 30 in the second direction and the third direction. The second connection structure 323 is a fixed connection structure, which is detachably connected to the adapter card assembly 30 to fix the handle bar 300 to the adapter card assembly 30.

[0093] In this way, the handle bar 300 and the adapter card assembly 30 can be easily assembled and disassembled.

[0094] Exemplarily, the plug-in structure is an integral structure with the first connector 310. For example, the plug-in structure may be an insert tongue of the first connector 310 extending in the first direction away from the second end 312.

[0095] Exemplarily, the first support member 210 of the bracket 200 has an inserting interface, and the inserting structure is inserted into the inserting interface of the first support member 210 of the bracket 200 .

[0096] Exemplarily, the fixed connection structure is detachably connected to the second supporting member 220 of the bracket 200 .

[0097] Exemplarily, the fixed connection structure can be detachably connected to the second support member 220 by fastener connection, snap connection, compression fixation, etc.

[0098] Exemplarily, the fixed connection structure may include a connection plate, one side of which is connected to the fourth end 322 , the connection plate extends along the third direction away from the board 400 , and the connection plate is detachably connected to the second support member 220 .

[0099] Exemplarily, the connecting plate and the second connecting member 320 are an integral structure, and the connecting plate is a folded edge structure at the end of the second connecting member 320 .

[0100] In some examples, a pressing member (not shown) may be provided on the second support member 220, the pressing member is located on a side of the second support member 220 away from the first support member 210, and a connecting plate may be inserted between the pressing member and the second support member 220, and the pressing member may press and fix the connecting plate on the second support member 220, so as to fix the handle bar 300 to the second support member 220. In this way, the disassembly and assembly between the handle bar 300 and the bracket 200 may be more convenient.

[0101] In other examples, the connection plate may be detachably connected to the second support member 220 by bolts passing through the connection plate and the second support member 220 .

[0102] In some possible implementations, the first connecting member 310 is slidably connected to the second connecting member 320 , and the second connecting member 320 can slide along the first direction relative to the first connecting member 310 .

[0103] In this way, the distance between the first connection structure 313 and the second connection structure 323 can be changed by the relative sliding of the first connection member 310 and the second connection member 320, the second connection member 320 has better stability when extending and retracting along the first direction, and the first connection member 310 and the second connection member 320 are not prone to bending, which is conducive to the fixation of the handle bar 300 and the adapter card assembly 30. In addition, the structure of the handle bar 300 can also be made simpler.

[0104] In an example where the first connecting member 310 and the second connecting member 320 are slidably connected, in the first direction, the third end 321 is located between the first end 311 and the second end 312 , and the second end 312 is located between the first end 311 and the fourth end 322 .

[0105] Figure 4 A schematic diagram of a first connecting member provided in an embodiment of the present application.

[0106] like Figure 4 As shown, in some possible embodiments, the first connecting member 310 includes a first side edge 314 and a third side edge 316 , the first side edge 314 and the third side edge 316 are respectively located on both sides of the first connecting member 310 in the second direction, and a slide structure 315 is provided at the first side edge 314 .

[0107] Figure 5 A schematic diagram of a second connecting member provided in an embodiment of the present application.

[0108] like Figure 5 As shown, the second connecting member 320 includes a second side edge 324 and a fourth side edge 326 , which are respectively located at two sides of the second connecting member 320 in the second direction, and a sliding connection structure 325 is provided at the second side edge 324 .

[0109] Figure 6 This is a schematic diagram of a handle bar provided in an embodiment of the present application when it is retracted. Figure 7 for Figure 6 Schematic diagram of the handle bar extended.

[0110] like Figure 6 , Figure 7 As shown, the first connecting member 310 and the second connecting member 320 are slidably connected via a slideway structure 315 and a sliding connection structure 325 .

[0111] In this way, the slide structure 315 and the sliding connection structure 325 are respectively located on the sides of the first connecting member 310 and the second connecting member 320. The set slide structure 315 and the sliding connection structure 325 are not easy to interfere with the arrangement of other components, which facilitates the assembly between the board 400 and the handle strip 300.

[0112] The first side edge 314 and the second side edge 324 are located at the same side of the handle bar 300 in the second direction, and the third side edge 316 and the fourth side edge 326 are located at the same side of the handle bar 300 in the second direction.

[0113] Exemplarily, the slide structure 315 and the board 400 may be located on the same side of the first connector 310 in the third direction.

[0114] Figure 8 A schematic diagram of another first connecting member provided in an embodiment of the present application.

[0115] like Figure 8 As shown, and see Figure 6 , Figure 7 In some possible implementations, the slideway structure 315 includes a first folding structure 3151, a second folding structure 3152, and a third folding structure 3153. The first folding structure 3151, the second folding structure 3152, and the third folding structure 3153 are an integral structure with the first connector 310. One side of the first folding structure 3151 is connected to the first side 314, the first folding structure 3151 extends along the third direction, the other side of the first folding structure 3151 is connected to one side of the second folding structure 3152, the second folding structure 3152 extends along the second direction toward the third side 316, the other side of the second folding structure 3152 is connected to one side of the third folding structure 3153, the third folding structure 3153 extends along the third direction toward the first connecting member 310, a gap 3154 is formed between the other side of the third folding structure 3153 and the first connecting member 310, and the first folding structure 3151, the second folding structure 3152 and the third folding structure 3153 are surrounded to form a slide groove 3155. The second connecting member 320 is inserted into the gap 3154 between the third folding structure 3153 and the first connecting member 310.

[0116] In this way, it is easier to form the slide structure 315 on the first connecting member 310, and no other fixing structure is required between the slide structure 315 and the first connecting member 310, so that the first connecting member 310 provided with the slide structure 315 can have a simpler structure and a smaller size.

[0117] Both ends of the slide groove 3155 extend along the first direction, and both ends of the slide groove 3155 in the first direction are open structures.

[0118] Fig. 9 A schematic diagram of another second connecting member provided in an embodiment of the present application.

[0119] like Fig. 9 As shown, the sliding connection structure 325 includes a fourth folding structure 3251, one side of the fourth folding structure 3251 is connected to the second side 324, and the fourth folding structure 3251 extends along the third direction.

[0120] like Figure 6-Figure 9 As shown, the fourth folding structure 3251 is inserted into the slide groove 3155, and the fourth folding structure 3251 is slidably matched with the slide groove 3155. The fourth folding structure 3251 can slide along the first direction relative to the slide groove 3155.

[0121] In this way, it is relatively easy to form a sliding connection structure 325 on the second connecting member 320 that slides with the slide structure 315. No other fixed structure is required between the sliding connection structure 325 and the second connecting member 320, so that the structure of the second connecting member 320 provided with the sliding connection structure 325 is simpler and smaller in size.

[0122] In other examples, the slide structure 315 may include a slide, which may be fixedly disposed on the first connecting member 310 by welding, fastener connection, etc. The sliding connection structure 325 may include a slider, which may be fixedly disposed on the second connecting member 320 by welding, bonding, etc. The slider is disposed in the slide and slidably cooperates with the slide (not shown).

[0123] Fig.10 A schematic diagram of a board provided in an embodiment of the present application.

[0124] Exemplarily, the board 400 includes a board circuit board 410 and a third connector 420, the third connector 420 is disposed on the board circuit board 410 and is electrically connected to the board circuit board 410, the board circuit board 410 is fixedly connected to the first connector 310, and the board circuit board 410 can be perpendicular to the second direction. The third connector 420 is located at one end of the board circuit board 410 in the third direction, the third connector 420 protrudes from the board circuit board 410, and the third connector 420 is used to connect to an external device, and the board circuit board 410 includes a gold finger connector, which is located on the side of the board circuit board 410 away from the fourth end 322 in the first direction.

[0125] Fig.11 A schematic diagram of a handle bar of another board and card assembly provided in an embodiment of the present application when retracted.

[0126] like Fig.11 As shown, and see Figure 7 , Fig.10The third side 316 of the first connector 310 is provided with a fixing plate 318, the fixing plate 318 protrudes from the first connector 310 along the third direction, and the first connector 310 is fixedly connected to the board 400 through the fixing plate 318. Specifically, the first connector 310 is fixedly connected to the board circuit board 410 through the fixing plate 318.

[0127] In this way, the board 400 can be used to have a larger contact area with the fixing plate 318, so that the board 400 can be more firmly connected to the first connecting member 310. In addition, the fixing plate 318 protruding from the first connecting member 310 can also make it easier to fix the board 400 and the first connecting member 310. In addition, the board 400 can be fixedly connected to the side of the first connecting member 310 away from the slide structure 315 through the fixing plate 318, so that there is a larger gap between the board 400 and the slide structure 315, which is conducive to the second connecting member 320 slidably connected to the first connecting member 310 to avoid the board 400.

[0128] The fixing plate 318 and the slide structure 315 may be located on the same side of the first connecting member 310 in the third direction, the fixing plate 318 and the connecting plate may be located on different sides of the first connecting member 310 in the third direction, and the fixing plate 318 may be perpendicular to the second direction.

[0129] Exemplarily, the fixing plate 318 may be fixedly connected to the card circuit board 410 by welding, bonding, fastener connection, etc.

[0130] Exemplarily, the third side 316 is provided with a plurality of fixing plates 318 spaced apart along the first direction, and the first connector 310 can be fixedly connected to the board 400 through the plurality of fixing plates 318. In this way, the first connector 310 can be connected to the board 400 more stably.

[0131] Exemplarily, the fixing plate 318 and the first connecting member 310 are an integral structure, and the fixing plate 318 may be a folded edge structure of the first connecting member 310 .

[0132] Exemplarily, in the third direction, the first connector 310 and the board circuit board 410 are spaced apart, and the second connector 320 is located between the first connector 310 and the board circuit board 410. In this way, the board circuit board 410 will not hinder the sliding of the second connector 320, so that the second connector 320 can be easily extended.

[0133] In some examples, the fixing plate 318 has a first assembly hole 3181, and the board circuit board 410 has a second assembly hole 411 corresponding to the first assembly hole 3181. The fixing plate 318 and the board circuit board 410 are detachably connected via fasteners passing through the first assembly hole 3181 and the corresponding second assembly hole 411.

[0134] In this way, the board 400 and the first connecting member 310 can be easily assembled and disassembled.

[0135] The first connector 310 has connector installation openings 317 corresponding to the third connectors 420 one by one. The connector installation openings 317 penetrate the first connector 310 along the third direction, and the third connectors 420 are inserted into the corresponding connector installation openings 317 .

[0136] Fig.12 This is a schematic diagram of another handle bar extended according to an embodiment of the present application. Fig.13 for Fig.12 Schematic diagram of the handle bar being retracted.

[0137] like Fig.12 , Fig.13 As shown, in some possible embodiments, the third end 321 has an avoidance gap 327, and the avoidance gap 327 is an open structure on the side away from the second side edge 324. The avoidance gap 327 is used to avoid the connector installation port 317 so that the connector installation port 317 is located outside the sliding path of the second connecting member 320.

[0138] Fig.14 A schematic diagram of a handle bar of another board and card assembly provided in an embodiment of the present application when extended. Fig.15 for Fig.14 Schematic diagram of the board assembly handle bar when it is retracted.

[0139] like Fig.14 , Fig.15 As shown, after the board 400 is installed on the first connector 310 , the avoidance gap 327 is used to avoid the third connector 420 inserted into the connector installation opening 317 , so that the third connector 420 is located outside the sliding path of the second connector 320 .

[0140] In this way, the third connector 420 inserted into the connector installation opening 317 will not block the sliding of the second connector 320 , thereby facilitating the extension and retraction of the second connector 320 .

[0141] Fig.16 This is a schematic diagram of another handle bar extended according to an embodiment of the present application. Fig.17 for Fig.16 Schematic diagram of the handle bar being retracted.

[0142] like Fig.16 , 17As shown, in some possible embodiments, the handle bar 300 further includes a foldable shielding member 330. The shielding member 330 includes a fifth end 331 and a sixth end 332, the fifth end 331 and the sixth end 332 are respectively located at two ends of the shielding member 330 in the first direction, the fifth end 331 is fixedly connected to the first connecting member 310, and the sixth end 332 is fixedly connected to the second connecting member 320. In the first direction, the connector installation port 317 is located between the fifth end 331 and the first end 311, and the sixth end 332 is located between the avoidance notch 327 and the fourth end 322. The second connecting member 320 sliding in the first direction toward the direction close to the first end 311 is used to fold the shielding member 330. The second connecting member 320 sliding in the first direction toward the direction away from the first end 311 is used to unfold the shielding member 330. When the end of the avoidance gap 327 close to the fourth end 322 is located between the second end 312 and the fourth end 322, the avoidance gap 327 includes a hollow portion 3271 (such as Fig.12 ) and an overlapping portion (not shown) between the third end 321 and the second end 312 , the shielding member 330 is used to shield the hollow portion 3271 .

[0143] Fig.18 A schematic diagram of a handle bar of another board and card assembly provided in an embodiment of the present application when extended. Fig.19 for Fig.18 Schematic diagram of the board assembly handle bar when it is retracted.

[0144] like Fig.18 , Fig.19 As shown, after the board 400 is installed on the first connector 310 , in the first direction, the third connector 420 passing through the connector installation opening 317 is located between the fifth end 331 and the first end 311 .

[0145] In this way, the shielding member 330 can block the debris that enters the handle bar 300 through the hollow portion 3271 and is provided on the side of the board 400, thereby reducing the influence of the debris on the operation of the board 400.

[0146] The hollow portion 3271 and the overlapping portion change as the second connector 320 slides relative to the first connector 310. When the second connector 320 is close to the first end 311, the hollow portion 3271 is smaller and the overlapping portion is larger. When the second connector 320 is away from the first end 311, the hollow portion 3271 is larger and the overlapping portion is smaller. In some examples, the end of the avoidance gap 327 close to the fourth end 322 can slide between the first end 311 and the second end 312. When the end of the avoidance gap 327 close to the fourth end 322 is located between the first end 311 and the second end 312, the avoidance gap 327 does not include the hollow portion 3271.

[0147] For example, the shielding member 300 may be located on a side of the second connecting member 320 away from the first connecting member 310 in the third direction, so that the shielding member 300 is unlikely to block the sliding of the second connecting member 320 .

[0148] Exemplarily, the shielding member 330 may be a corrugated shielding sheet made of rubber, plastic or the like.

[0149] Exemplarily, the shielding member 330 may include a telescopic bracket 200 and a curtain disposed on the surface of the telescopic bracket 200, wherein the telescopic bracket 200 includes a fifth end 331 and a sixth end 332. The second connecting member 320 sliding in the first direction toward the direction close to the first end 311 is used to shrink the telescopic bracket 200 so that the curtain is folded. The second connecting member 320 sliding in the first direction toward the direction away from the first end 311 is used to extend the telescopic bracket 200 so that the curtain is unfolded. The curtain is used to shield the hollow portion 3271 (not shown).

[0150] Exemplarily, the shielding member 330 may include a plurality of shielding blades hinged in sequence, and a first hinge seat hinged to the shielding blade at the front and a second hinge seat hinged to the shielding blade at the rear, respectively, the first hinge seat includes a fifth end 331, and the second hinge seat includes a sixth end 332. The second connecting member 320 sliding in the first direction toward the direction close to the first end 311 is used to fold the plurality of shielding blades. The second connecting member 320 sliding in the first direction toward the direction away from the first end 311 is used to unfold the plurality of shielding blades. The plurality of shielding blades are used to shield the hollow portion 3271 (not shown).

[0151] like Fig.14 , Fig.15 As shown, in other examples, the handle bar 300 may not include the shielding member 330 , and the hollow portion 3271 may be used for air flow, thereby improving the heat dissipation performance of the board 400 .

[0152] In some other possible embodiments, the handle bar 300 may further include a telescopic member, one end of which is fixedly connected to the first connecting member 310, and the other end of which is fixedly connected to the second connecting member 320, and the second connecting member 320 is telescopically connected to the second end 312 (not shown) through the telescopic member. Exemplarily, the telescopic member may include but is not limited to a telescopic rod, a telescopic frame, etc.
