Technical Field

[0001] This application relates to the technical field of board installation, specifically to a board assembly device and a server. Background Art

[0002] With the rapid development of technology, the scale of data centers has been continuously climbing, putting forward new requirements for the high-speed interconnection of components such as processors and memories inside computing servers; high-density connectors and other plug interfaces have the advantages of large data throughput, good transmission stability, strong anti-interference ability, and high compatibility, and thus are widely used in servers.

[0003] However, the plugging and unplugging actions of high-density connectors and other plug interfaces require a considerable amount of force. Whether during the server production process or the maintenance process, it will bring inconvenience to operators, reduce the production and maintenance efficiency, increase the production and maintenance costs, and may also damage the connectors and boards due to improper operation, affecting product reliability. Summary of the Invention

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

[0005] On the one hand, this application provides a board assembly device, including two slide rail assemblies and a tray assembly. The specific solutions are as follows.

[0006] The two slide rail assemblies are arranged side by side at intervals. A driving part and a guiding part are arranged on the slide rail assemblies; the tray assembly is located between the two slide rail assemblies and is slidably connected to the guiding part. A wrench is rotatably arranged on the tray assembly. The tray assembly is used to set a first board and a first plugging part, and the first board is connected to the first plugging part;

[0007] Among them, the wrench cooperates with the driving part to control the plugging or disconnection of the first plugging part and the target component.

[0008] Beneficial effects: By rotatably arranging a wrench on the tray assembly and arranging a driving part on the slide rail assembly, the wrench and the driving part cooperate with each other by rotating the wrench, so that the tray assembly slides reciprocally along the plugging direction of the first plugging part, thereby realizing the plugging or disconnection of the first plugging part on the tray assembly and the target component; the wrench is rotatably connected to the tray assembly to form a labor-saving lever, which can reduce the operation force, improve the plugging and unplugging speed, improve the production and maintenance efficiency, and reduce the production and maintenance costs.

[0009] Meanwhile, during the rotation of the wrench, the two moving limit positions of the tray assembly can be the state where the first plugging part is plugged into the target component in place and the state where the first plugging part is separated from the target component, enabling stable switching between the two, ensuring the plugged state, reducing the probability of plugging fatigue and damage between the first plugging part and the target component, thereby improving the reliability of the product.

[0010] Furthermore, the board card assembly device in the present application occupies a small space and can be applied to 1U servers ("U" (Unit) is the height measurement unit when devices such as servers are installed in a rack, 1U≈1.75 inches, approximately 4.445 cm).

[0011] On the other hand, the present application also provides a server, including a second board card and the above-mentioned board card assembly device. The second board card is provided with a second plugging part; the first board card is fixed on the tray assembly, and the wrench cooperates with the driving part to control the plugging or disconnection of the first plugging part and the second plugging part.

[0012] Beneficial effects: Since the server includes the board card assembly device, it has the same technical effects as the board card assembly device, which will not be elaborated here. Description of the Drawings

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] Combine the following Figures 1 to 13 , describing an embodiment of the present application.

[0044] 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.

[0045] like Figure 6 and Figure 7As shown, the slide rail assembly 1 is a plastic part, which is integrally formed by an injection molding process or can also be formed by splicing; two slide rail assemblies 1 are used to be connected to the chassis base 5 by screws and are arranged side by side at intervals. The drive part 11 and the guide part 12 are arranged on the slide rail assembly 1. Generally, both the drive part 11 and the guide part 12 are grooves with a certain guiding function.

[0046] As Figure 3 shown, the tray assembly 2 is located between the two slide rail assemblies 1. Wrenches 21 are rotatably arranged at both ends of the tray assembly 2 along the side-by-side direction of the two slide rail assemblies 1. A drive block 211 is arranged on the wrench 21; the tray assembly 2 is used to arrange the first circuit board 3 and the first plug-in part 31. The first circuit board 3 is connected to the first plug-in part 31, and the first plug-in part 31 is used to be plugged into the target part (i.e., the second plug-in part 41) fixed in the chassis.

[0047] It should be noted that the first plug-in part 31 can be an integral structure with the first circuit board 3, and the first plug-in part 31 is fixed on the tray assembly 2 through the first circuit board 3; the first plug-in part 31 can also be connected to the first circuit board 3 through a wire harness or a flexible circuit board, etc., and then are respectively fixed on the tray assembly 2.

[0048] As Figure 3 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 part of the tray assembly 2 through a rotating shaft. The distance between the drive block 211 and the rotating shaft is between 10 mm and 30 mm; the drive block 211 is a cylindrical block, and the edge of the drive block 211 is polished.

[0049] In another embodiment, the drive part 11 can also be the drive block 211, and a drive groove is arranged on the wrench 21, which can also realize the driving of the tray assembly 2.

[0050] Among them, the drive block 211 enters the drive part 11. With the reciprocating rotation of the wrench 21, the tray assembly 2 can be driven to reciprocate along the plugging direction of the first plug-in part 31, controlling the plugging or disconnection of the first plug-in part 31 and the target part (the second plug-in part 41); specifically, the tray assembly 2 can be reciprocally slidably connected to the two slide rail assemblies 1 along the plugging direction of the first plug-in part 31, or can also be reciprocally slidably connected to other components on the chassis base 5 along the plugging direction of the first plug-in part 31.

[0051] In the specific use process, taking a server as an example, specifically, as Figure 1As shown, two slide rail assemblies 1 are fastened to the chassis base 5 of the server by screws. A second board 4 is provided on the chassis base 5. The second plugging portion 41 is a high-density connector seat, 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 by a wire 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. The high-density connection plug is the first plugging portion 31.

[0052] During the plugging operation, as Figure 3 shown, by synchronously rotating the wrench 21, the driving block 211 on the wrench 21 enters the driving portion 11. Then, under the guiding drive of the driving portion 11, the tray assembly 2 moves along the plugging direction of the first plugging portion 31 towards the high-density connector seat, and the high-density connection plug on the first board 3 enters the high-density connector seat for plugging.

[0053] During the unplugging operation, as Figure 3 shown, by synchronously rotating the wrench 21, the driving block 211 on the wrench 21 gradually slides out of the driving portion 11. And under the guiding drive of the driving portion 11, the tray assembly 2 moves along the plugging direction of the first plugging portion 31 away from the high-density connector seat, and the high-density connection plug on the first board 3 slides out of the high-density connector seat to achieve disconnection.

[0054] 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. Thus, by rotating the wrench 21, the cooperation between the wrench 21 and the driving portion 11 is used to make the tray assembly 2 reciprocally slide along the plugging direction of the first plugging portion 31, so as to realize the plugging and disconnection between the first plugging 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 operation force, improve the plugging and unplugging speed, improve the production and maintenance efficiency, and reduce the production and maintenance cost.

[0055] At the same time, during the rotation of the wrench 21, the two moving limit positions of the tray assembly 2 can be the state where the first plugging portion 31 is plugged in place with the target component and the state where the first plugging portion 31 is separated from the target component, which can realize stable switching between the two, not only ensure the plugging state, but also reduce the probability of plugging fatigue and damage between the first plugging portion 31 and the target component, so as to improve the reliability of the product.

[0056] Furthermore, the board assembly device in this application occupies a small space and can be applied to a 1U server ( "U" (Unit) is a height measurement unit when servers and other devices are installed in a rack, 1U≈1.75 inches, about 4.445 cm).

[0057] In one embodiment, as Figure 6As shown, at least one guiding portion 12 is further provided on the sliding rail assembly 1. Specifically, the number of the guiding portions 12 may be 1 to 3, preferably 2, which are arranged at intervals along the insertion direction of the first insertion portion 31, and there may be a height difference between the two guiding portions 12 in the height direction of the sliding rail assembly 1; the guiding portion 12 extends along the insertion direction of the first insertion portion 31, wherein the height direction of the sliding rail is the direction perpendicular to both the insertion direction of the first insertion portion 31 and the side-by-side direction of the two sliding rail assemblies 1.

[0058] As Figure 3 As shown, at least one guiding block 22 is provided at both ends of the tray assembly 2 along the side-by-side direction of the two sliding rail assemblies 1. The guiding block 22 is in the shape of a cylinder, and the edge is polished. The number of the guiding blocks 22 is 1 to 3, and they are arranged in one-to-one correspondence with the guiding portions 12; among them, a plurality of guiding blocks 22 and a plurality of guiding portions 12 are in one-to-one correspondence, and the guiding block 22 can reciprocate and slide into the guiding portion 12. Specifically, the guiding portion 12 is a groove body, which can limit the guiding block 22 in the height direction of the sliding rail assembly 1.

[0059] In this embodiment, by providing the guiding portion 12 on the sliding rail assembly 1 to slidably connect with the guiding block 22 on the tray assembly 2, the tray assembly 2 can be guided along the insertion direction of the first insertion portion 31, the stability of the reciprocating sliding of the tray assembly 2 in the insertion direction of the first insertion portion 31 can be improved, thereby improving the insertion stability between the first insertion portion 31 and the target component, reducing the damage probability of the first insertion portion 31 and the target component, and improving the reliability of the server.

[0060] In some embodiments not shown, at least one guiding portion 12 is provided on both side surfaces of the tray assembly 2 along the side-by-side direction of the two sliding rail assemblies 1. Specifically, the number of the guiding portions 12 may be 1 to 3, preferably 2, which are arranged at intervals along the insertion direction of the first insertion portion 31, and there may be a height difference between the two guiding portions 12 along the height direction of the sliding rail assembly 1; the guiding portion 12 extends along the insertion direction of the first insertion portion 31.

[0061] At least one guiding block 22 is provided on the side surfaces of the two sliding rail assemblies 1 close to the tray assembly 2. The guiding block 22 is in the shape of a cylinder, and the edge is polished. The number of the guiding blocks 22 is 1 to 3, and they are arranged in one-to-one correspondence with the guiding portions 12; among them, a plurality of guiding blocks 22 and a plurality of guiding portions 12 are in one-to-one correspondence, and the guiding block 22 can reciprocate and slide into the guiding portion 12. Specifically, the guiding portion 12 is a groove body, which can limit the guiding block 22 in the height direction of the sliding rail assembly 1.

[0062] In one embodiment, as Figure 6As 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°.

[0063] 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 .

[0064] 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 .

[0065] 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.

[0066] 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.

[0067] 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.

[0068] Specifically, the driving part 11 is arranged on the slide rail body 13 and close to the side surface of the tray assembly 2, and the locking part 14 is arranged on the side surface 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 reciprocally slide 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 part 14 has a locking position and an unlocking position.

[0069] As Figure 3 shown, a first locking hole 131 is arranged on the slide rail body 13, and the first locking hole 131 communicates with the guiding part 12. A first locking block 141 is arranged on the locking part 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 it can only meet the requirement that the first locking block 141 can pass through; the first locking block 141 penetrates through the first locking hole 131; wherein, when the locking part 14 is in the locking position, the first locking block 141 can limit the guiding block 22 to prevent the guiding block 22 from moving in the direction away from the first plugging part 31.

[0070] Specifically, a groove can be arranged on the first locking block 141. When in the locking position, the end of the guiding block 22 away from the tray assembly 2 enters the groove to lock the position of the guiding block 22.

[0071] It should be noted that there can be multiple first locking blocks 141, and there can also be multiple first locking holes 131, which communicate with the multiple guiding parts 12 respectively; the guiding block 22 and the rotating shaft of the handle have different heights in the height direction of the slide rail assembly 1.

[0072] In the specific use process, as Figure 3 and Figure 5 shown, after the plugging action is completed, that is, after the wrench 21 completes rotation and the first plugging part 31 is plugged with the second plugging part 41, the locking part 14 is moved to the locking position, so as to limit the guiding block 22 through the first locking block 141, and it can prevent the tray assembly 2 from moving in the direction away from the second plugging part 41.

[0073] In this embodiment, as Figure 3 and Figure 5 shown, by arranging the locking part 14 on the side of the slide rail assembly 1 away from the tray assembly 2, arranging the first locking block 141 on the locking part 14, and arranging the first locking hole 131 communicating with the guiding part 12 on the slide rail assembly 1, so that when in the locking position, the guiding block 22 can be limited to prevent the guiding block 22 from moving in the direction away from the second plugging part 41, so that the first locking block 141 and the wrench 21 lock the position of the tray assembly 2 at the same time, to reduce the poor plugging between the first plugging part 31 and the second plugging part 41, and further improve the reliability of the product.

[0074] In one embodiment, as Figure 5 shown, a plurality of continuous sawteeth 1411 are provided at an end of the first locking block 141 close to the tray assembly 2. Specifically, the depth and slope of the sawteeth 1411 can be set according to actual requirements; as Figure 4 shown, an inclined surface 221 is provided at an end of the guiding block 22 away from the tray assembly 2. The arrangement of the inclined surface 221 which is in limit fit with the sawteeth 1411 on the first locking block 141 can facilitate the clamping connection between the guiding block 22 and the sawteeth 1411.

[0075] It should be noted that the plurality of continuous sawteeth 1411 can also be used for clamping different-sized boards. For example, the positions of the first insertion portions 31 on different boards are slightly different along the insertion direction of the first insertion portions 31. The plurality of continuous sawteeth 1411 can adapt to the position locking of different boards or absorb the position tolerances of different first insertion portions 31 on the tray assembly 2 to avoid incomplete insertion, thereby improving the reliability of the product.

[0076] In this embodiment, as Figure 5 and Figure 4 shown, by providing a plurality of continuous sawteeth 1411 and an inclined surface 221 at an end of the guiding block 22 away from the tray assembly 2, it can facilitate the limit connection between the guiding block 22 and the first locking block 141 and improve the position locking accuracy of the tray assembly 2.

[0077] In one embodiment, as Figure 5 shown, in the locking position, the locking member 14 can lock the position of the wrench 21 when the first insertion portion 31 is in the inserted state.

[0078] Specifically, as Figure 5 shown, a second locking block 142 is further provided on the locking member 14. Specifically, the first locking block 141 is one of a cylindrical shape, a cuboid shape, etc. 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 can allow the second locking block 142 to pass through. The second locking block 142 penetrates through the second locking hole 132, and a locking position hole 212 is provided on the wrench 21; wherein, in the locking position, the second locking block 142 can penetrate through the locking position hole 212 on the wrench 21 to lock the position of the wrench 21.

[0079] In the specific use process, as Figure 5As shown, after the wrench 21 rotates to the position where the insertion is completed, the locking hole 212 just coincides with the second locking hole 132, so that the locking member 14 is moved from the unlocked position to the locked position. 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.

[0080] In this embodiment, by providing the second locking block and the second locking hole 212, and providing the locking hole 212 on the wrench 21, the locking member 14 can be used to simultaneously lock the wrench 21 and the guiding block 22 on the tray assembly 2, so as to ensure the insertion state of the first insertion portion 31 and the second insertion portion 41 and improve the reliability of the server.

[0081] 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 insertion portion 31 is inserted in place.

[0082] In one embodiment, as Figure 3 shown, the locking member 14 is provided with at least two through holes 143. As Figure 3 shown, at least two connecting members 133 are provided on the slide rail body 13. The connecting members 133 penetrate through the through holes 143 and are slidably connected to the through holes 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.

[0083] Specifically, as Figures 7 to 9 shown, among them, Figure 8 and Figure 9 in the figure, the connecting column 1331 is a schematic diagram of a structure with half 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 method. A limiting portion is provided at the other end of the elastic reset member to limit the contact with the surface of the locking member 14 away from the slide rail body 13. Through the elastic deformation of the elastic reset member 1332, the locking member 14 can be in the locked position and the unlocked position.

[0084] In this embodiment, the locking member is 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 limits the locking member 14 through the elastic reset member 1332, so that the position of the locking member 14 can be changed to realize the locked position and the unlocked position. The structure is simple and the operation is convenient.

[0085] In some embodiments not shown, a threaded hole and a locking member are provided on the locking member 14. The locking member is screwed into the threaded hole and can penetrate 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 formed between the locking member 14 and the slide rail body 13 to achieve the unlocking position and the locking position of the locking member 14.

[0086] In a specific embodiment, as Figures 7 to 9 shown, wherein, Figure 8 and Figure 9 In, the connecting column 1331 in the figure is a schematic diagram of a structure with half cut away. 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 means of threaded or interference fit hole-shaft fitting. A receiving groove 13311 is provided at the second end of the connecting column 1331. One end of the elastic reset member 1332 is fixed in the receiving groove 13311 by means of glue bonding or bolt fixed connection. At least a part of the other end of the elastic reset member 1332 is slidably sleeved on the connecting column 1331 and limits the locking member 14.

[0087] Specifically, as Figures 8 to 10 shown, wherein, Figure 9 and Figure 10 In, the connecting column 1331 in the figure is a schematic diagram of a structure with half cut away. One end of the elastic reset member 1332 is in a stepped cylinder shape or a cylinder shape and can be sleeved on the connecting column 1331. The other end of the elastic reset member 1332 is an elastic telescopic member and is connected to the inner bottom of the receiving groove 13311 on the connecting column 1331.

[0088] In this embodiment, by fixedly connecting one end of the elastic reset member 1332 to the inner bottom of the connecting column 1331 and slidably sleeving the other end of the elastic reset member 1332 on the connecting column 1331, the limiting stability of the connecting member 133 can be improved and the operation is facilitated.

[0089] In an embodiment, as Figures 8 to 10 shown, wherein, Figure 9 and Figure 10In [the figure], the connecting column 1331 in the figure is a schematic diagram of a structure with half removed. The elastic reset member 1332 includes a spring 13321 and a sliding member 13322. The spring 13321 is arranged in the accommodation groove 13311. One end of the spring 13321 is connected to the inner bottom of the accommodation groove 13311 by means of bolt screwing or glue bonding. The other end of the spring 13321 is connected to the sliding member 13322 by means of welding or clamping. Specifically, the sliding member 13322 is provided with a convex limit, and the end of the spring 13321 is provided with a hanging ear, and the hanging ear can be hooked with the convex limit. One end of the connecting column 1331 away from the slide rail body 13 is provided with a chute, and the chute penetrates through the accommodation groove 13311. A part of the sliding member 13322 is slidably connected to the chute, and the part of the sliding member 13322 located outside the chute is in limiting contact with the locking member 14.

[0090] Specifically, as Figures 9 to 10 shown, among which, Figure 9 and Figure 10 In [the figure], the connecting column 1331 in the figure is a schematic diagram of a structure with half removed. The sliding member 13322 includes a slide rod and a sleeved part. The slide rod penetrates through the chute. A part of the slide rod located in the accommodation groove 13311 is connected to the spring 13321. The sleeved part is sleeved on the connecting column 1331 and is connected to the slide rod. The sleeved part can be circular, square, or arc-shaped.

[0091] In this embodiment, by providing a chute on the connecting column 1331, the elastic connecting member 133 includes a spring 13321 and a sliding member 13322. A part of the sliding member 13322 penetrates through the chute and is slidably connected to the chute along the side-by-side direction of the two slide rail assemblies 1. Other parts of the sliding member 13322 can be slidably sleeved on the connecting column 1331, with a simple structure and better stability.

[0092] In one embodiment, as Figures 8 to 9 shown, the chute penetrates 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 chute can slide out of the chute.

[0093] In the specific use process, taking the sliding member 13322 including a slide rod and a sleeved part, the slide rod penetrating through the chute, a part of the slide rod located in the accommodation groove 13311 being connected to the spring 13321, the sleeved part being sleeved on the connecting column 1331 and being connected to the slide rod, and the sleeved part being circular as an example.

[0094] Before disassembling the tray assembly 2, first slide the sliding rod out of the sliding groove and rotate it 90° around the axis of the connecting column 1331. Thus, the sliding rod can be supported on the end face of the connecting column 1331 away from the slide rail body 13, separating the sliding member 13322 from the locking member 14 and not limiting the locking member 14. Thereby, the locking member 14 can be moved from the locking position to the unlocking position, which is convenient to operate and does not require a locking position member, further simplifying the structure.

[0095] In one embodiment, as Figure 3 and Figure 5 shown, a pulling part 144 is provided on the side of the locking member 14 away from the slide rail body 13. Specifically, the pulling part 144 is an arc-shaped pull rod. The middle part of the arc-shaped pull rod is spaced 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 as to facilitate the position movement of the locking member 14.

[0096] In one embodiment, the driving part 11 extends in a direction away from the target component and is arranged crosswise to the insertion direction of the first insertion part 31. Specifically, as Figure 6 shown, the driving part 11 extends in the insertion direction of the first insertion part 31, away from the first insertion part 31, and is inclined towards the chassis base 5, that is, the driving part 11 is inclined. By the inclined setting, the driving block 211 is driven to reciprocate along the insertion direction of the first insertion part 31.

[0097] Specifically, the driving part 11 can be an inclined straight groove or an arc-shaped groove, as long as it can guide and drive the driving block 211.

[0098] In this embodiment, by extending the driving part 11 in an inclined manner, the displacement amount of the tray assembly 2 can be realized to achieve the insertion of the first insertion part 31 and the second insertion part 41.

[0099] In some embodiments not shown, the driving part 11 can also extend along the height direction of the slide rail assembly 1, and an inclined surface is provided at the opening of the driving part 11 to increase the displacement amount of the tray assembly 2.

[0100] In one embodiment, as Figure 6 shown, the driving part 11 is arc-shaped. During the insertion process of the first insertion part 31, the driving part 11 can make the moving speed of the tray assembly 2 along the insertion direction of the first insertion part 31 increase gradually first and then decrease gradually. That is, during the insertion process of the first insertion part 31, the displacement amount of the tray assembly 2 in the insertion direction of the first insertion part 31 per unit time increases gradually first and then decreases gradually.

[0101] Specifically, as Figure 6As shown, the driving part 11 includes a connected first arc groove 111 and second arc groove 112. The center of the first arc groove 111 is closer to the first plug-in part 31 than the center of the second arc groove 112; the center of the second arc groove 112 is closer to the chassis base 5 than the center of the first arc groove 111; the central angles of both the first arc groove 111 and the second arc groove 112 are right angles.

[0102] During the specific use process, as Figure 6 shown, since the first plug-in part 31 and the second plug-in part 41 need to be aligned before plugging, when the driving block 211 enters the first arc groove 111, the displacement change amplitude (moving speed) of the arc groove along the plugging direction of the first plug-in part 31 is small, making the approaching speed of the first plug-in part 31 and the second plug-in part 41 slow, which is convenient for pre-positioning the first plug-in part 31 and the second plug-in part 41. After the pre-guidance of the first plug-in part 31 and the second plug-in part 41 is completed, at this time, the driving block 211 enters the second half of the first arc groove 111 and the first half of the second arc groove 112. During this process, the displacement change rate (moving speed) of the driving block 211 along the plugging direction of the first plug-in part 31 is large, enabling rapid plugging.

[0103] As Figure 6 shown, when the driving block 211 enters the second half of the second arc groove 112, since its displacement change amount (moving speed) along the plugging 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 before the plugging is completed, reducing the deformation amount of the first plug-in part 31 and the second plug-in part 41 and ensuring the plugging effect.

[0104] In this embodiment, by making the first plug-in part 31 move slowly relative to the second plug-in part 41 in the first half of the first arc segment and the second half of the second arc segment, it is possible to prevent damage caused by the misalignment of the first plug-in part 31 and the second plug-in part 41 and the inability to correct it in time; and prevent the first plug-in part 31 and the second plug-in part 41 from being plugged at the same speed all the time, resulting in a large deformation amount of the first plug-in part 31 and the second plug-in part 41 and poor plugging, thereby improving the reliability of the product.

[0105] In one embodiment, as Figure 1 shown, the first plug-in part 31 includes a first plug-in member 311 and two first guiding members 312; the two first guiding members 312 are respectively located on both sides of the first plug-in member 311; as Figure 1 shown, the second plug-in part 41 includes a second plug-in member 411 and two second guiding members 412, and the two second guiding members 412 are respectively located on both sides of the second plug-in member 411; wherein, the first plug-in member 311 is used for plugging with the second plug-in member 411, and the two first guiding members 312 are respectively used for guiding connection with the two second guiding members 412.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] In one embodiment, Figure 11 and Figure 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 .

[0110] like Figure 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.

[0111] As Figure 11 and Figure 12 As shown, the bottom plate of the tray assembly 2 is provided with an I-shaped nail hoist hole 25 for sliding connection with the chassis base 5.
