Description

Technical Field

[0001] The present application relates to the technical field of board installation, and in particular to a board assembly device and a server. Background Art

[0002] With the rapid development of technology, the scale of data centers continues to rise, which puts forward new requirements for the high-speed interconnection of processors, memory and other components inside computing servers. High-density connectors and other plug-in interfaces have the advantages of large data throughput, good transmission stability, strong anti-interference ability and high compatibility, and are therefore widely used in servers.

[0003] However, the plugging and unplugging of high-density connectors and other plug-in interfaces requires considerable force, which will cause inconvenience to operators both during server production and maintenance, reduce production and maintenance efficiency, and increase production and maintenance costs. It may also cause damage to connectors and boards due to improper operation, affecting product reliability. Summary of the invention

[0004] The present application provides a board assembly device and a server, which can improve production and maintenance efficiency, reduce production and maintenance costs, and improve product reliability.

[0005] On the one hand, the present application provides a board assembly device, including two slide rail assemblies and a tray assembly, and the specific scheme is as follows.

[0006] Two slide rail assemblies are arranged side by side and at intervals, and a driving part and a guide part are arranged on the slide rail assemblies; a tray assembly is located between the two slide rail assemblies and is slidably connected with the guide part, a wrench is rotatably arranged on the tray assembly, and a first board and a first plug-in part are arranged on the tray assembly, and the first board is connected to the first plug-in part; The wrench cooperates with the driving part to control the first plug-in part to be plugged in or disconnected from the target component.

[0007] Beneficial effects: A wrench is rotatably provided on the tray assembly, and a driving part is provided on the slide rail assembly, so that by rotating the wrench, the wrench and the driving part cooperate to make the tray assembly slide back and forth along the plug-in direction of the first plug-in part, thereby realizing the plug-in or disconnection of the first plug-in part on the tray assembly with the target component; the wrench is rotatably connected to the tray assembly to form a labor-saving lever, which can reduce the operating force and increase the plug-in and pull-out speed, thereby improving the production and maintenance efficiency and reducing the production and maintenance costs.

[0008] At the same time, during the rotation of the wrench, the two extreme movement positions of the tray assembly can be a state in which the first plug-in portion and the target component are plugged in place, and a state in which the first plug-in portion and the target component are separated. Stable switching between the two can be achieved, which can not only ensure the plug-in state, but also reduce the plug-in fatigue between the first plug-in portion and the target component, resulting in the probability of damage, thereby improving the reliability of the product.

[0009] Again, the board assembly device in the present application takes up little space and can be used in a 1U server ("U" (Unit) is the unit of measurement for the height of a server or other equipment when it is installed in a rack, 1U≈1.75 inches, approximately 4.445 cm).

[0010] On the other hand, the present application also provides a server, including a second board and the above-mentioned board assembly device, the second board is provided with a second plug-in portion; the first board is fixed on the tray assembly, and the wrench cooperates with the driving portion to control the first plug-in portion and the second plug-in portion to be plugged in or disconnected.

[0015] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0016] In related technologies, with the rapid development of technology, the scale of data centers continues to rise, which puts forward new requirements for the high-speed interconnection of processors, memory and other components inside computing servers; high-density connectors and other plug-in interfaces have the advantages of large data throughput, good transmission stability, strong anti-interference ability and high compatibility, and are therefore widely used in servers.

[0017] However, the plugging and unplugging of high-density connectors and other plug-in interfaces requires considerable force, which will cause inconvenience to operators both during server production and maintenance, reduce production and maintenance efficiency, and increase production and maintenance costs. It may also cause damage to connectors and boards due to improper operation, affecting product reliability.

[0018] In order to solve the above problems, the present application provides a board assembly device and a server, which can improve production and maintenance efficiency, reduce production and maintenance costs, and improve product reliability.

[0019] Combine the following Figures 1 to 13 , describing an embodiment of the present application.

[0020] According to an embodiment of the present application, on the one hand, a board assembly device is provided, such as Figure 2 As shown, it includes two slide rail assemblies 1 and a tray assembly 2, and the specific scheme is as follows.

[0021] like Figure 6 and Figure 7 As shown, the slide rail assembly 1 is a plastic part, which is made of one piece through injection molding process, and can also be assembled by splicing; the two slide rail assemblies 1 are used to connect with the chassis base 5 through screws, and are arranged side by side at intervals. The slide rail assembly 1 is provided with a driving part 11 and a guide part 12, and the driving part 11 and the guide part 12 are generally grooves with certain guiding functions.

[0022] like Figure 3As shown, the tray assembly 2 is located between the two slide rail assemblies 1, and wrenches 21 are rotatably provided at both ends of the tray assembly 2 along the parallel direction of the two slide rail assemblies 1, and a driving block 211 is provided on the wrench 21; the tray assembly 2 is used to set a first board 3 and a first plug-in portion 31, the first board 3 is connected to the first plug-in portion 31, and the first plug-in portion 31 is used to be plugged with a target component (i.e., the second plug-in portion 41) fixed in the chassis.

[0023] It should be explained that the first plug-in portion 31 can be an integral structure with the first board 3, and the first plug-in portion 31 can be fixed to the tray assembly 2 through the first board 3; the first plug-in portion 31 can also be connected to the first board 3 through a wiring harness or a flexible circuit board, etc., and then fixed on the tray assembly 2 respectively.

[0024] like Figure 3 As shown, specifically, the wrench 21 is made of metal or plastic, the first end of the wrench 21 is rotatably connected to the main body of the tray assembly 2 via a rotating shaft, the distance between the driving block 211 and the rotating shaft is between 10 mm and 30 mm; the driving block 211 is a cylindrical block, and the edge of the driving block 211 is polished.

[0025] In another embodiment, the driving portion 11 may also be a driving block 211 , and a driving groove is provided on the wrench 21 , so that the tray assembly 2 can also be driven.

[0026] Among them, the driving block 211 enters the driving part 11, and with the reciprocating rotation of the wrench 21, it can drive the tray assembly 2 to slide back and forth along the plug-in direction of the first plug-in part 31, and control the first plug-in part 31 to be plugged in or disconnected from the target component (the second plug-in part 41); specifically, the tray assembly 2 can be reciprocatingly slidably connected with the two slide rail assemblies 1 along the plug-in direction of the first plug-in part 31, and can also be reciprocatingly slidably connected with other components on the chassis base 5 along the plug-in direction of the first plug-in part 31.

[0027] In the specific use process, taking the server as an example, specifically, Figure 1 As shown, the two slide rail assemblies 1 are fastened to the chassis base 5 of the server by screws, the chassis base 5 is provided with a second board 4, the second plug-in portion 41 is a high-density connection socket, which is provided on the second board 4. Of course, it can also be provided on the chassis base 5 and connected to the second board 4 through a wiring harness. The first board 3 is fixed to the tray assembly 2 by screws, and a high-density connection plug is provided on the first board 3, and the high-density connection plug is the first plug-in portion 31.

[0028] During the plug-in operation, Figure 3As shown, by synchronously rotating the wrench 21, the driving block 211 on the wrench 21 enters the driving part 11, and then under the guidance and drive of the driving part 11, the tray assembly 2 moves along the plug-in direction of the first plug-in part 31 toward the direction close to the high-density connection seat, and the high-density connection plug on the first board 3 enters the high-density connection seat for plugging.

[0029] During the unplugging operation, if Figure 3 As shown, by synchronously rotating the wrench 21, the driving block 211 on the wrench 21 gradually slides out from the driving part 11, and under the guidance and drive of the driving part 11, the tray assembly 2 moves along the plug-in direction of the first plug-in part 31 away from the high-density connection seat, and the high-density connection plug on the first board 3 slides out from the high-density connection seat to achieve disconnection.

[0030] In this embodiment, a wrench 21 is rotatably provided on the tray assembly 2, and a driving portion 11 is provided on the slide rail assembly 1, so that by rotating the wrench 21, the wrench 21 and the driving portion 11 cooperate to make the tray assembly 2 slide back and forth along the plugging direction of the first plug-in portion 31, thereby realizing the plugging and disconnection of the first plug-in portion 31 on the tray assembly 2 and the target component; the wrench 21 is rotatably connected to the tray assembly 2 to form a labor-saving lever, which can reduce the operating force and increase the plugging and unplugging speed, thereby improving the production and maintenance efficiency and reducing the production and maintenance costs.

[0031] At the same time, during the rotation of the wrench 21, the two moving limit positions of the tray assembly 2 can be a state in which the first plug-in portion 31 and the target component are plugged in place, and a state in which the first plug-in portion 31 and the target component are separated. Stable switching between the two can be achieved, which can not only ensure the plug-in state, but also reduce the plug-in fatigue between the first plug-in portion 31 and the target component, resulting in the probability of damage, thereby improving the reliability of the product.

[0032] Again, the board assembly device in the present application takes up little space and can be used in a 1U server ("U" (Unit) is the unit of measurement for the height of a server or other equipment when it is installed in a rack, 1U≈1.75 inches, approximately 4.445 cm).

[0033] In one embodiment, Figure 6 As shown, at least one guide portion 12 is also provided on the slide rail assembly 1. Specifically, the number of the guide portions 12 can be 1 to 3, preferably 2, which are arranged at intervals along the plug-in direction of the first plug-in portion 31, and the two guide portions 12 can have a drop in the height direction of the slide rail assembly 1; the guide portion 12 extends along the plug-in direction of the first plug-in portion 31, wherein the height direction of the slide rail is a direction perpendicular to both the plug-in direction of the first plug-in portion 31 and the side-by-side direction of the two slide rail assemblies 1.

[0034] like Figure 3As shown, at least one guide block 22 is provided at both ends of the tray assembly 2 along the side-by-side direction of the two slide rail assemblies 1. The guide block 22 is in the shape of a cylinder with polished edges. The number of the guide blocks 22 is 1 to 3, which are arranged one-to-one with the guide portions 12; wherein, a plurality of guide blocks 22 correspond one-to-one with a plurality of guide portions 12, and the guide block 22 can enter the guide portion 12 and slide back and forth. Specifically, the guide portion 12 is a groove body, which can limit the guide block 22 along the height direction of the slide rail assembly 1.

[0035] In this embodiment, a guide portion 12 is provided on the slide rail assembly 1 to be slidably connected to the guide block 22 on the tray assembly 2, so that the tray assembly 2 can be guided along the plug-in direction of the first plug-in portion 31, thereby improving the stability of the reciprocating sliding of the tray assembly 2 in the plug-in direction of the first plug-in portion 31, thereby improving the plug-in stability between the first plug-in portion 31 and the target component, reducing the probability of damage to the first plug-in portion 31 and the target component, and improving the reliability of the server.

[0036] In some embodiments not shown, at least one guide portion 12 is provided on both side surfaces of the tray assembly 2 along the side-by-side direction of the two slide rail assemblies 1. Specifically, the number of the guide portions 12 may be 1 to 3, preferably 2, which are arranged at intervals along the plug-in direction of the first plug-in portion 31, and the two guide portions 12 may have a drop in the height direction of the slide rail assembly 1; the guide portion 12 extends along the plug-in direction of the first plug-in portion 31.

[0037] At least one guide block 22 is provided on the side surfaces of the two slide rail assemblies 1 close to the tray assembly 2. The guide block 22 is in the shape of a cylinder with polished edges. The number of the guide blocks 22 is 1 to 3, which are arranged one-to-one in correspondence with the guide portions 12; wherein, a plurality of guide blocks 22 correspond one-to-one to a plurality of guide portions 12, and the guide block 22 can enter the guide portion 12 and slide back and forth. Specifically, the guide portion 12 is a groove body, which can limit the guide block 22 along the height direction of the slide rail assembly 1.

[0038] In one embodiment, Figure 6 As shown, the guide portion 12 includes a first guide groove 121 and a second guide groove 122 that are connected, the second guide groove 122 extends along the plug-in direction of the first plug-in portion 31, the first guide groove 121 and the second guide groove 122 are set at an angle, and extend to the edge of the slide rail assembly 1, that is, the angle between the first guide groove 121 and the second guide groove 122 is 30°~90°, preferably, the connection part between the first guide groove 121 and the second guide groove 122 is in an arc transition shape, wherein the angle between the first guide groove 121 and the second guide groove 122 is preferably any one of 30°, 60° and 90°.

[0039] Specifically, the first guide groove 121 is contracted in a direction approaching the second guide groove 122 , or the end of the first guide groove 121 away from the second guide groove 122 is V-shaped, which can facilitate the guide block 22 to enter the first guide groove 121 .

[0040] In the specific use process, such as Figure 3 and Figure 6 As shown, the guide block 22 of the tray assembly 2 is first inserted into the first guide groove 121 , and then, under the guidance of the first guide groove 121 , it enters the second guide groove 122 , and then the wrench 21 is rotated to insert the tray assembly 2 .

[0041] In this embodiment, the guide portion 12 includes a first guide groove 121 and a second guide groove 122, and the first guide groove 121 extends along the height direction of the slide rail assembly 1 to the edge of the slide rail assembly 1, and the second guide groove 122 extends along the plug-in direction of the first plug-in portion 31, thereby facilitating the guide block 22 to enter the second guide groove 122, simplifying the operation, and having a simple structure.

[0042] In some embodiments not shown, the drive block 211 can be configured to be retractable along the side-by-side direction of the two slide rail assemblies 1, and elastically retract into the tray assembly 2. When the drive block 211 is aligned with the guide portion 12, it pops out into the guide portion 12. However, this solution is not convenient for separating the tray assembly 2 from the slide rail assembly 1.

[0043] In one embodiment, Figure 3 and Figure 4 As shown, the slide rail assembly 1 includes a slide rail body 13 and a locking member 14. Specifically, the slide rail body 13 and the locking member 14 are both plastic parts, and are both formed by an integral injection molding process; the locking member 14 has a locking position and an unlocking position. When the locking member 14 is in the locking position, it can limit the portion of the tray assembly 2 that slides with the guide portion 12 (i.e., the guide block 22) to prevent the tray assembly 2 from moving in a direction away from the target component.

[0044] Specifically, the driving part 11 is arranged on the slide rail body 13 and on the side close to the tray assembly 2. The locking member 14 is arranged on the side of the slide rail body 13 away from the tray assembly 2 and can move relative to the slide rail body 13. Specifically, it can slide back and forth along the side-by-side direction of the two slide rail assemblies 1 (i.e., the direction away from the tray assembly 2), so that the locking member 14 has a locking position and an unlocking position.

[0045] like Figure 3As shown, a first locking hole 131 is provided on the slide rail body 13, and the first locking hole 131 is connected to the guide portion 12. A first locking block 141 is provided on the locking member 14. Specifically, the first locking block 141 can be cylindrical, rectangular, etc. The profile of the first locking hole 131 can match the shape of the first locking block 141, or only allow the first locking block 141 to pass through; the first locking block 141 passes through the first locking hole 131; wherein, when the locking member 14 is in the locked position, the first locking block 141 can limit the guide block 22 to prevent the guide block 22 from moving in a direction away from the first plug-in portion 31.

[0046] Specifically, a groove may be provided on the first locking block 141 , and in the locking position, one end of the guide block 22 away from the tray assembly 2 enters into the groove to lock the position of the guide block 22 .

[0047] It should be noted that there may be multiple first locking blocks 141 and multiple first locking holes 131, which are respectively connected to multiple guide parts 12; the heights of the guide block 22 and the rotating shaft of the handle along the height direction of the slide rail assembly 1 are different.

[0048] In the specific use process, such as Figure 3 and Figure 5 As shown, after the plug-in action is completed, that is, the wrench 21 completes the rotation, the first plug-in part 31 and the second plug-in part 41 are plugged in, and the locking member 14 is moved to the locking position, thereby limiting the guide block 22 through the first locking block 141, thereby preventing the tray assembly 2 from moving in a direction away from the second plug-in part 41.

[0049] In this embodiment, if Figure 3 and Figure 5 As shown, a locking member 14 is provided on a side of the slide rail assembly 1 away from the tray assembly 2, a first locking block 141 is provided on the locking member 14, and a first locking hole 131 is provided on the slide rail assembly 1 to communicate with the guide portion 12, so that in the locked position, the guide block 22 can be limited to prevent the guide block 22 from moving in a direction away from the second plug-in portion 41, so that the first locking block 141 and the wrench 21 simultaneously lock the position of the tray assembly 2 to reduce the poor connection between the first plug-in portion 31 and the second plug-in portion 41, thereby improving the reliability of the product.

[0050] In one embodiment, Figure 5 As shown, the first locking block 141 is provided with a plurality of continuous saw teeth 1411 at the end close to the tray assembly 2. Specifically, the depth and slope of the saw teeth 1411 can be set according to actual needs; Figure 4As shown, a chamfered surface 221 is provided at the end of the guide block 22 away from the tray assembly 2 , and the setting of the chamfered surface 221 cooperates with the sawtooth 1411 on the first locking block 141 to facilitate the locking connection between the guide block 22 and the sawtooth 1411 .

[0051] It should be noted that multiple continuous serrations 1411 can also be used to connect boards and cards of different sizes. For example, the positions of the first plug-in portions 31 on different boards and cards along the plug-in direction of the first plug-in portions 31 are slightly different, and multiple continuous serrations 1411 can adapt to the position locking of different boards and cards, or absorb the position tolerances of different first plug-in portions 31 on the tray assembly 2 to avoid improper plug-in, thereby improving the reliability of the product.

[0052] In this embodiment, if Figure 5 and Figure 4 As shown, by providing a plurality of continuous saw teeth 1411 and providing a chamfered surface 221 at the end of the guide block 22 away from the tray assembly 2, it is possible to facilitate the limiting connection between the guide block 22 and the first locking block 141, thereby improving the position locking accuracy of the tray assembly 2.

[0053] In one embodiment, Figure 5 As shown, the locking member 14 is in the locking position, and can lock the position of the wrench 21 when the first plug-in portion 31 is in the plugged state.

[0054] Specifically, Figure 5 As shown, the locking member 14 is also provided with a second locking block 142. Specifically, the first locking block 141 is one of a cylindrical shape, a rectangular shape, etc., and a second locking hole 132 is provided on the slide rail body 13. The shape of the second locking hole 132 matches the shape of the first locking block 141, or the second locking block 142 can pass through the second locking hole 132. The second locking block 142 passes through the second locking hole 132, and a locking hole 212 is provided on the wrench 21; wherein, when the locking member 14 is in the locked position, the second locking block 142 can pass through the locking hole 212 on the wrench 21 to lock the position of the wrench 21.

[0055] In the specific use process, such as Figure 5 As shown, when the wrench 21 is rotated to the position where the insertion is completed, the locking hole 212 coincides with the second locking hole 132, thereby moving the locking member 14 from the unlocking position to the locking position, and the second locking block 142 can pass through the second locking hole 132 and enter the locking hole 212 to lock the position of the wrench 21.

[0056] In this embodiment, by providing a second locking block and a second locking hole 212, and providing a locking hole 212 on the wrench 21, the locking member 14 can be used to synchronously lock the wrench 21 and the guide block 22 on the tray assembly 2 to ensure the plug-in state of the first plug-in portion 31 and the second plug-in portion 41, thereby improving the reliability of the server.

[0057] In some embodiments not shown, a limiting rod is provided on the locking member 14 , and the limiting rod can limit the edge of the wrench 21 to prevent the wrench 21 from loosening after the first plug-in portion 31 is plugged into place.

[0058] In one embodiment, Figure 3 As shown, the locking member 14 is provided with at least two through holes 143, such as Figure 3 As shown, at least two connecting members 133 are provided on the slide rail body 13. The connecting members 133 pass through the through hole 143 and are slidably connected to the through hole 143. An elastic reset member 1332 is fixedly provided at one end of the connecting member 133 away from the slide rail body 13 for keeping the locking member 14 in the locked position.

[0059] Specifically, Figures 7 to 9 As shown, Figure 8 and Fig. 9 In the figure, the connecting column 1331 is a schematic diagram of the structure with half of it cut off, one end of the elastic reset member 1332 is connected to the connecting member 133 by an integral molding method, the connecting member 133 is connected to the slide rail body 13 by a threaded connection, and the other end of the elastic reset member 1332 is provided with a limiting portion to contact with the surface of the locking member 14 away from the slide rail body 13, and the locking member 14 can be in a locked position and an unlocked position through the elastic deformation of the elastic reset member 1332.

[0060] In this embodiment, the lock will be slidably connected to the slide rail body 13 along the side-by-side direction of the two slide rail assemblies 1 through two connecting members 133, and the end of the connecting member 133 away from the slide rail body 13 is limited by the elastic reset member 1332, so that the locking member 14 can be changed in position to achieve the locking position and the unlocking position. The structure is simple and the operation is convenient.

[0061] In some embodiments not shown, a threaded hole and a locking member are provided on the locking member 14. The locking member is screwed to the threaded hole and penetrates through the threaded hole to contact the slide rail body 13. By controlling the length of the locking member extending out of the threaded hole, a gap is created between the locking member 14 and the slide rail body 13, thereby achieving the unlocking position and locking position of the locking member 14.

[0062] In a specific embodiment, Figures 7 to 9 As shown, Figure 8 and Fig. 9In the figure, the connecting column 1331 is a schematic diagram of the structure with half of it cut off, and the connecting member 133 includes a connecting column 1331 and an elastic reset member 1332. The first end of the connecting column 1331 passes through the through hole 143 and is connected to the slide rail body 13 by a thread or an interference fit hole-shaft fit. The second end of the connecting column 1331 is provided with a receiving groove 13311, and one end of the elastic reset member 1332 is fixed in the receiving groove 13311 by glue bonding or bolt fixing, and at least a part of the other end of the elastic reset member 1332 is slidably sleeved on the connecting column 1331 to limit the locking member 14.

[0063] Specifically, Figures 8 to 10 As shown, Fig. 9 and Fig.10 In the figure, the connecting column 1331 is a schematic structural diagram with half of it cut off, one end of the elastic reset member 1332 is in a stepped cylindrical or cylindrical shape, which can be sleeved on the connecting column 1331, and the other end of the elastic reset member 1332 is an elastic telescopic member, which is connected to the bottom of the accommodating groove 13311 on the connecting column 1331.

[0065] In one embodiment, Figures 8 to 10 As shown, Fig. 9 and Fig.10 In the figure, the connecting column 1331 is a schematic diagram of the structure cut in half, and the elastic reset member 1332 includes a spring 13321 and a sliding member 13322. The spring 13321 is arranged in the accommodating groove 13311, and one end of the spring 13321 is connected to the inner bottom of the accommodating groove 13311 by bolt threading or glue bonding, and the other end of the spring 13321 is connected to the sliding member 13322 by welding or clamping. Specifically, a protruding limit is provided on the sliding member 13322, and a hanging ear is provided at the end of the spring 13321, which can be hung with the protruding limit, and a sliding groove is provided at the end of the connecting column 1331 away from the slide rail body 13, and the sliding groove passes through the accommodating groove 13311, and a part of the sliding member 13322 is slidably connected to the sliding groove, and the part of the sliding member 13322 located outside the sliding groove is in contact with the locking member 14.

[0066] Specifically, Figures 9 and 10 As shown, Fig. 9 and Fig.10In the figure, the connecting column 1331 is a schematic structural diagram with half of it cut off, and the sliding member 13322 includes a sliding rod and a sleeve portion, the sliding rod passes through the sliding groove, and a part of the sliding rod located in the accommodating groove 13311 is connected to the spring 13321, and the sleeve portion is sleeved on the connecting column 1331 and connected to the sliding rod. The sleeve portion can be in a circular ring shape, a square ring shape, or an arc shape.

[0067] In this embodiment, a sliding groove is set on the connecting column 1331, and the elastic connecting member 133 includes a spring 13321 and a sliding member 13322. A part of the sliding member 13322 passes through the sliding groove and is slidingly connected with the sliding groove along the side-by-side direction of the two slide rail assemblies 1. The other parts of the sliding member 13322 can be slidably mounted on the connecting column 1331, which has a simple structure and better stability.

[0068] In one embodiment, Figures 8 to 9 As shown, the slide groove passes through the end of the connecting column 1331 away from the slide rail body 13, that is, a part of the sliding member 13322 located in the slide groove can slide out of the slide groove.

[0069] In specific use, the sliding member 13322 includes a sliding rod and a sleeve portion, the sliding rod passes through the sliding groove, a part of the sliding rod located in the accommodating groove 13311 is connected to the spring 13321, the sleeve portion is sleeved on the connecting column 1331 and connected to the sliding rod, and the sleeve portion is in a circular ring shape.

[0070] Before disassembling the tray assembly 2, first slide the slide rod out of the slide groove and rotate it 90° around the axis of the connecting column 1331, so that the slide rod can be supported on the end face of the connecting column 1331 away from the slide rail body 13, so that the sliding member 13322 is separated from the locking member 14, and the locking member 14 is not limited, so that the locking member 14 can be moved from the locked position to the unlocked position. The operation is convenient and there is no need to set a locking member, which further simplifies the structure.

[0071] In one embodiment, Figure 3 and Figure 5 As shown, a handle portion 144 is provided on the side of the locking member 14 away from the slide rail body 13. Specifically, the handle portion 144 is an arc-shaped pull rod, the middle portion of the arc-shaped pull rod is spaced apart from the main body of the locking member 14, and both ends of the arc-shaped pull rod are connected to the locking member 14, so that the locking member 14 can be easily moved.

[0072] In one embodiment, the driving portion 11 extends in a direction away from the target component and is arranged to intersect with the plugging direction of the first plugging portion 31. Figure 6As shown, the driving part 11 extends along the plugging direction of the first plugging part 31, in a direction away from the first plugging part 31, and is inclined in a direction close to the chassis base 5, that is, the driving part 11 is inclined, and is driven by the inclined setting to reciprocate the driving block 211 along the plugging direction of the first plugging part 31.

[0073] Specifically, the driving portion 11 may be an inclined linear groove or an arc-shaped groove, as long as it can guide and drive the driving block 211 .

[0074] In this embodiment, the driving portion 11 is extended and arranged to be inclined, so that the displacement of the tray assembly 2 can be achieved, thereby realizing the insertion and assembly of the first plug-in portion 31 and the second plug-in portion 41 .

[0075] In some embodiments not shown, the driving portion 11 may also extend in the height direction of the slide rail assembly 1 , and an inclined surface is provided at the opening of the driving portion 11 to increase the displacement of the tray assembly 2 .

[0076] In one embodiment, Figure 6 As shown, the driving portion 11 is in an arc shape. During the plugging process of the first plug-in portion 31, the driving portion 11 can make the moving speed of the tray assembly 2 along the plugging direction of the first plug-in portion 31 gradually increase first, and then gradually decrease. That is, during the plugging process of the first plug-in portion 31, the displacement of the tray assembly 2 in the plugging direction of the first plug-in portion 31 per unit time first increases gradually, and then gradually decreases.

[0077] Specifically, Figure 6 As shown, the driving portion 11 includes a first arcuate groove 111 and a second arcuate groove 112 which are connected. The center of the first arcuate groove 111 is closer to the first plug-in portion 31 than the center of the second arcuate groove 112; the center of the second arcuate groove 112 is closer to the chassis base 5 than the center of the first arcuate groove 111; the center angle of the first arcuate groove 111 and the center angle of the second arcuate groove 112 are both right angles.

[0078] In the specific use process, such as Figure 6 As shown, since the first plug-in portion 31 and the second plug-in portion 41 need to be aligned before plugging, when the drive block 211 enters the first arc-shaped groove 111, the displacement change amplitude (moving speed) of the arc-shaped groove along the plug-in direction of the first plug-in portion 31 is small, so that the approach speed of the first plug-in portion 31 and the second plug-in portion 41 is slow, which is convenient for the first plug-in portion 31 and the second plug-in portion 41 to be pre-positioned. After the pre-guiding of the first plug-in portion 31 and the second plug-in portion 41 is completed, at this time, the drive block 211 enters the second half of the first arc-shaped groove 111 and the first half of the second arc-shaped groove 112. During this process, the displacement change rate (moving speed) of the drive block 211 along the plug-in direction of the first plug-in portion 31 is large, which can achieve quick plug-in.

[0079] like Figure 6 As shown, when the drive block 211 enters the second half of the second arc groove 112, since its displacement change (moving speed) in the plug-in direction of the first plug-in part 31 is small, the first plug-in part 31 and the second plug-in part 41 can be slowly plugged in before the plug-in is completed, thereby reducing the deformation of the first plug-in part 31 and the second plug-in part 41 and ensuring the plug-in effect.

[0080] In this embodiment, by slowly moving the first plug-in portion 31 relative to the second plug-in portion 41 in the first half of the first arc segment and the second half of the second arc segment, it is possible to prevent the first plug-in portion 31 and the second plug-in portion 41 from being misaligned and unable to be corrected in time, causing damage; and to prevent the first plug-in portion 31 and the second plug-in portion 41 from always being plugged in at the same speed, causing a large deformation of the first plug-in portion 31 and the second plug-in portion 41 and causing poor plug-in, thereby improving the reliability of the product.

[0081] In one embodiment, Figure 1 As shown, the first plug-in portion 31 includes a first plug-in component 311 and two first guide components 312; the two first guide components 312 are respectively located on both sides of the first plug-in component 311; Figure 1 As shown, the second plug-in portion 41 includes a second plug-in component 411 and two second guide components 412, and the two second guide components 412 are respectively located on both sides of the second plug-in component 411; wherein, the first plug-in component 311 is used for plugging with the second plug-in component 411, and the two first guide components 312 are respectively used for guiding connection with the two second guide components 412.

[0082] In this embodiment, by providing a first guide member 312 on each side of the first connector 311 to provide double-sided guidance, the position accuracy of the plug-in can be improved and the probability of damage to the first connector 311 and the second connector 411 can be reduced.

[0083] In one embodiment, Figure 2 As shown, the end of the first connector 311 is in a pyramidal shape, a guide hole is provided on the second guide member 412, the end face of the guide hole is a concave pyramidal surface, first magnets are provided on both surfaces of the end of the first connector 311 along the height direction of the slide rail assembly 1, second magnets are provided on both surfaces of the concave pyramidal surface of the guide hole along the height direction of the slide rail assembly 1, and the first magnet and the second magnet are arranged to attract each other.

[0084] In this embodiment, the end of the first connector 311 is formed into a pyramid shape, a guide hole is provided on the second guide member 412, the end face of the guide hole is a concave pyramid surface, and a first magnet and a second magnet that attract each other are provided respectively, so that during the pre-guiding process, the mutual attraction between the first magnet and the second magnet can ensure the accuracy of the pre-guiding position.

[0085] In one embodiment, Fig.11 and Fig.12 As shown, the side wall and the bottom plate of the tray assembly 2 close to the first plug-in portion 31 are provided with a folded edge 23 for riveting to improve the strength of the tray assembly 2 .

[0086] like Fig.13 As shown, the bottom plate end of the tray assembly 2 close to the first plug-in portion 31 is provided with a raised folded edge 24 for easy guiding.

[0087] like Fig.11 and Fig.12 As shown, the bottom plate of the tray assembly 2 is provided with an I-pin hoist hole 25 for sliding connection with the chassis base 5 .
