Description

Technical Field

[0001] The present application relates to the technical field of servers, and in particular to a server flip mechanism, a server chassis, and a server. Background Art

[0002] To accommodate sufficient components within a compact server chassis while ensuring high maintainability, servers are typically equipped with a flip mechanism. During server maintenance, the flip mechanism flips the upper node away from the lower node, creating sufficient space between the upper and lower nodes for maintenance, allowing maintenance to be completed without removing the server from the chassis.

[0003] In the related art, when the flip mechanism performs a flipping action, the flipping part is prone to lateral displacement relative to the chassis, which causes the flipping part to easily touch other components in the chassis, making it difficult to complete the flipping action and causing inconvenience to the maintenance of the server. Summary of the Invention

[0004] The present application provides a flip mechanism, a server chassis, and a server, to at least solve the problem in the related art that the flip mechanism easily comes into contact with other components in the chassis during the flipping process, making it difficult to complete the flipping action.

[0005] The present application provides a flipping mechanism, comprising:

[0006] A support, used for fixed connection to the server chassis;

[0007] a tray, hinged to the support and capable of rotating around the support in a first direction;

[0008] The deflection-correcting assembly is configured to drive the tray to move along a second direction perpendicular to the first direction, and to limit the tray from rotating within a lateral area in the second direction.

[0009] The present application also provides a server chassis, comprising:

[0010] Box;

[0011] A turning mechanism, wherein a support of the turning mechanism is fixedly connected to the box body.

[0012] The present application also provides a server, including:

[0013] Server chassis;

[0014] The server nodes, at least part of the server nodes, are arranged in the box body of the server chassis and the tray of the server chassis.

[0015] Through the present application, since the server is provided with a box and a flipping mechanism, the server nodes can be arranged in layers on the box and the trays of the server flipping structure. When performing maintenance work on the server nodes arranged in the box, it is only necessary to flip the tray of the flipping mechanism to expose the server nodes of the box, and then the server nodes of the box can be maintained. Since the flipping mechanism is provided with a correction component, the correction component can correct the pallet during the flipping process of the pallet, so that the pallet is always flipped within a range that will not touch other devices in the box. Therefore, the technical problem that the flipping mechanism is prone to touching other devices in the chassis during the flipping process can be effectively solved, thereby achieving the technical effect of facilitating server node maintenance.

[0032] The following will be combined with the accompanying drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limiting the present application. The terms "mounted," "connected," and "connected" should be interpreted broadly, and may include, for example, fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. The terms "parallel," "perpendicular," and "equal" encompass the described conditions and conditions similar to the described conditions, provided that the range of the similar conditions is within an acceptable range of deviation, as determined by a person of ordinary skill in the art taking into account the measurement in question and the errors associated with the measurement of the particular quantity (i.e., the limitations of the measurement system). For example, "parallel" includes both absolute parallelism and approximate parallelism, where the acceptable deviation range for approximate parallelism may be, for example, within 5°; "perpendicular" includes both absolute perpendicularity and approximate perpendicularity, where the acceptable deviation range for approximate perpendicularity may also be, for example, within 5°.

Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0034] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0035] As server architectures become increasingly complex, to accommodate sufficient components within a compact server chassis while also ensuring high maintainability, server chassis typically feature a flip mechanism. This mechanism houses the lower node and the upper node within the flip mechanism. During server maintenance, the flip mechanism flips the upper node away from the lower node, creating ample space between the two nodes for server maintenance, allowing maintenance to be completed without removing the server from the chassis.

[0036] In the related art, the width of the tray of the flip structure 20a of the server chassis is usually configured to be the same as the width of the chassis 10a, and the two sides of the tray are hinged to the side walls of the chassis 10a through a hinge structure. However, since the tray occupies the integrated lateral space of the chassis 10a, it is difficult to accommodate other devices between the tray and the side walls of the chassis 10a, which makes it difficult to configure higher components at the nodes below. Therefore, this type of flip structure 20a has great limitations and a narrow range of applications.

[0037] In order to arrange as many devices as possible in the narrow space of the chassis 10a, the tray of the flip structure 20a has another configuration form, that is, the width of the tray is configured to be smaller than the width of the chassis 10a, so that devices with a height exceeding the tray can be arranged between the tray 20 and the side wall of the chassis 10a. There are two assembly forms of the tray of this type of flip structure 20a. One is to hinge both sides of the tray to the bottom wall of the chassis 10a, and the other assembly form is as follows: Figure 1 As shown, one side of the tray is hinged to the side wall of the chassis 10a, while the other side is hinged to the bottom wall of the chassis 10a. However, the assembly method of hingedly connecting both sides of the chassis 10a to the bottom wall of the chassis 10a will result in the space between the tray and the side wall of the chassis 10a being too narrow, which will limit the types of devices that can be arranged. In order to increase the width of the space between the tray and the side wall of the chassis 10a so that a wider variety of devices can be accommodated between the tray and the side wall of the chassis 10a, the assembly method currently used is to hinge one side of the tray to the side wall of the chassis 10a, and the other side to the bottom wall of the chassis 10a.

[0038] The problem caused by hingedly connecting one side of the tray to the side wall of the chassis 10a and the other side to the bottom wall of the chassis 10a is: since the stiffness of the bottom wall of the chassis 10a is much smaller than the stiffness of the side wall of the chassis 10a, and the hinge support of the bottom wall of the chassis 10a has a large torque on the bottom wall of the chassis 10a, the deformation of the bottom wall of the chassis 10a is much greater than the deformation of the side wall of the chassis 10a, resulting in obvious deformation of the bottom wall of the chassis 10a, increasing the amount of shaking between the hinge support and the bottom wall of the chassis 10a, easily causing fatigue damage to the hinge support, and causing the hinge support arranged on the bottom wall of the chassis 10a to have a large displacement, while the stiffness of the side wall of the chassis 10a is large, the displacement of the hinge support at the side wall of the chassis 10a is small, and there is a displacement difference between the two hinge supports. Due to the differential deformation of the side and bottom walls of chassis 10a, as well as the displacement differences between the hinge supports on the side and bottom walls, the tray is prone to lateral deformation during flipping. Because the tray's sides are equipped with various components at the lower nodes, the tray's lateral deflection can easily contact these components, causing friction and jamming. This can inconvenience the tray's flipping and easily damage the components.

[0039] In order to solve the problem that the tray of the above-mentioned flipping structure 20a is prone to lateral displacement during the flipping process, and is prone to touching the side devices, causing friction and jamming, causing inconvenience to the flipping of the tray, and easily causing damage to the devices, the embodiment of the present application provides a flipping mechanism. The flipping mechanism corrects the flipped tray during the flipping action, thereby avoiding the tray from touching the side devices during the flipping process, and effectively solves the technical problem that the flipping mechanism is prone to touching other devices in the chassis 10a during the flipping process, causing friction and jamming, causing inconvenience to the flipping of the tray, and easily damaging the devices.

[0040] It should be noted that the flipping mechanism described in this application is used for but not limited to servers, and can also be applied to any other device platform with limited space. For the sake of convenience, in this application, only the application of the flipping mechanism to the server is used as an example. The principle of applying the flipping mechanism to other devices with limited space is essentially the same as that of applying it to the server, so they will not be repeated here.

[0041] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0042] In order to better understand this application, Figures 2 to 10 The technical solution of this application is described in detail:

[0043] like Figure 2 and Figure 3 As shown, the flip mechanism provided by the embodiment of the present application includes a support 10 and a tray 20. The support 10 is used to be fixedly connected to the server chassis. The tray 20 is hinged to the support 10 and can rotate around the support 10 in a first direction. Specifically, the flip mechanism can be fixed to the chassis 10a through the support 10. The tray 20 is hinged to the support 10 and can be flipped relative to the chassis 10a through the support 10. Nodes can be arranged on the bottom wall of the chassis 10a and the tray 20 to achieve a layered layout of the nodes. The nodes arranged on the bottom wall of the chassis 10a are defined as lower nodes, and the nodes arranged on the tray 20 are defined as upper nodes. When the tray 20 rotates around the support 10 in the first direction ( Figure 2 When the tray 20 is rotated in direction b), the tray 20 can be moved away from the lower node, exposing the lower node, thereby facilitating maintenance of the lower node, achieving a compact layout of the server nodes while not hindering server maintenance.

[0044] In this embodiment, the first direction is the rotation direction of the tray 20 during the flipping process.

[0045] In this embodiment, the length direction of the chassis 10a is defined as the longitudinal direction, the width direction of the chassis 10a is defined as the transverse direction, and after the flip mechanism is installed on the chassis 10a, the transverse direction of the chassis 10a is defined as the second direction ( Figure 2 The second direction is in the same direction as the rotation axis of the tray 20 and is perpendicular to the first direction.

[0046] In one embodiment, Figure 2 and Figure 3 As shown, the flipping mechanism also includes a correction component 30, which is configured to drive the tray 20 to move in a second direction perpendicular to the first direction, and limit the rotation of the tray 20 within a lateral area in the second direction. Specifically, the correction component 30 can correct the tray 20 during the flipping process of the tray 20, so that the tray 20 is always flipped within a range that will not touch other components in the case. Through the setting of the correction component 30, the flipping mechanism can limit the tray 20 to always flip within a limited lateral area. Within this area, the side of the tray 20 will not touch other components in the chassis 10a, thereby effectively solving the technical problem that the flipping mechanism is prone to touching other components in the chassis 10a during the flipping process, and facilitating the maintenance of server nodes.

[0047] It will be understood that the lateral area of ​​this embodiment is the area within which the tray 20 will not contact other components of the chassis 10a during the flipping process. This range is determined by the distance between the side of the tray 20 and the nearest component. Define this distance as Y, and the tray 20 is allowed to shift laterally within the range of 0-Y. That is, if the lateral offset of the tray 20 during the flipping process is less than or equal to Y, the tray 20 will not contact the component during the flipping process. If the lateral offset of the tray 20 during the flipping process is greater than Y, the tray 20 will contact the component during the flipping process. The function of the correction component 30 is to control the lateral offset of the tray 20 during the flipping process to within Y by correcting the tray 20 during the flipping process. If the lateral offset of the tray 20 during the flipping process is X, the correction amount Z of the correction component 30 should satisfy Z≥XY. To reduce the correction amount of the correction component 30, the correction amount Z of the correction component 30 is often set to Z=XY.

[0048] It is understandable that the support 10 can be any structure that can be fixed to the chassis 10a and for the tray 20 to be hinged.

[0049] It is understood that the support 10 can be fixed to any part of the chassis 10a, as long as it allows the tray 20 to be hingedly connected, allowing the tray 20 to be flipped relative to the chassis 10a. For example, the support 10 can be connected and fixed only to the bottom wall or side wall of the chassis 10a, so that the tray 20 is hingedly connected to the chassis 10a only through the bottom wall or side wall of the chassis 10a. The support 10 can also be connected and fixed to both the bottom wall and the side wall of the chassis 10a, thereby allowing the tray 20 to be hingedly connected to both the bottom wall and the side wall of the chassis 10a.

[0050] In one embodiment, in order to increase the space between the tray 20 and the side wall of the chassis 10a as much as possible, a part of the support 10 can be fixedly connected to the side wall of the chassis 10a, and the other part is fixed to the bottom wall of the chassis 10a, so that the tray 20 is hinged to the side fixed to the bottom wall of the chassis 10a and the side wall of the chassis 10a to form a larger accommodation space, which can accommodate various different devices and maximize the scope of use of the server flip structure 20a.

[0051] Specifically, if Figure 2 、 Figure 3 and Figure 4 As shown, the support 10 of this embodiment includes a bottom support 11 and a side support 12. The bottom support 11 is used to be fixedly connected to the bottom wall of the server chassis, and the side support 12 is used to be fixedly connected to the side wall of the server chassis. The two sides of the tray 20 are respectively hinged to the bottom support 11 and the side support 12. The bottom support 11 can be used to fix the support 10 to the bottom wall of the chassis 10a, and the side support 12 can be used to fix the support 10 to the side wall of the chassis 10a. By hingedly connecting the two sides of the tray 20 to the bottom support 11 and the side support 12, a layout scheme in which one side of the tray 20 is arranged on the side wall of the chassis 10a and the other side is arranged on the bottom wall of the chassis 10a can be implemented. Through this layout scheme, the space between the tray 20 and the side wall of the chassis 10a can be maximized, so that the space between the tray 20 and the side wall of the chassis 10a can meet the assembly requirements of various types of devices, thereby expanding the scope of application of the flip mechanism.

[0052] In this embodiment, since the support 10 is fixed to the bottom wall and side wall of the chassis 10a through the bottom support seat 11 and the side support seat 12 respectively, the tray 20 is easily offset laterally in the lateral direction of the chassis 10a during the flipping process, and collides with the devices on the side of the tray 20.

[0053] In order to reduce the deformation of the bottom wall of the chassis 10a during the turning process of the tray 20, in one embodiment, as shown in FIG. Figure 4As shown, the bottom support seat 11 includes a reinforcing beam 111 and a rotation bracket 112. The reinforcing beam 111 includes a supporting portion 1111 and a fixing portion 1112 arranged on both sides of the supporting portion 1111. A groove 1113 is formed between the fixing portion 1112 and the supporting portion 1111. The fixing portion 1112 is used to be fixed to the bottom wall of the server chassis. The supporting portion 1111 can be spaced apart from the bottom wall of the server chassis through the groove 1113. Specifically, the bottom support seat 11 is fixed to the box body through the reinforcing beam 111, and the rotation bracket 112 supports the tray 20 and is hinged to the tray 20. Since the reinforcing beam 111 includes a supporting portion 1111 and a fixing portion 1112 arranged on both sides of the supporting portion 1111, the reinforcing beam 111 can be fixed to the bottom wall of the chassis 10a through the fixing portions 1112 on both sides. Since a groove 1113 is formed between the fixing portion 1112 and the supporting portion 1111, the supporting portion 1111 can be spaced apart from the bottom wall of the chassis 10a, so that the force of the reinforcing beam 111 can be transmitted to the bottom wall of the chassis 10a through the two side portions, so that the rotation bracket 112 is not directly connected to the bottom wall of the chassis 10a, thereby reducing the deformation of the bottom wall.

[0054] It is understood that the fixing portion 1112 can be fixed to the bottom wall of the chassis 10a by welding, clamping, or other connection methods, and only needs to be able to achieve stability on the bottom wall of the chassis 10a. In one embodiment, the fixing portion 1112 is provided with a plurality of threaded mounting holes, and the fixing portion 1112 is fastened to the bottom wall of the chassis 10a by threaded connectors.

[0055] In order to reduce the deformation of the bottom wall of the chassis 10a during the turning process of the tray 20, in one embodiment, as shown in FIG. Figure 5As shown, the support portion 1111 includes an extension section 11111 and a support section 11112. Both the extension section 11111 and the support section 11112 extend in the second direction. The support section 11112 is connected to the extension section 11111 and has a width greater than that of the extension section 11111. The rotation bracket 112 is fixed to the support section 11112. Specifically, the support section 11112 can be fixed to the rotation bracket 112 to provide support for the tray 20. The extension section 11111 extends in the second direction (the width direction of the chassis 10a), thereby increasing the length of the support portion 1111 in the second direction, thereby increasing the contact area between the reinforcing beam 111 and the bottom wall of the chassis 10a and reducing the deformation of the bottom wall of the chassis 10a. The extension section 11111 can also guide the deflection of the tray 20, so that the tray 20 only deflects in the extension direction of the extension section 11111 of the support portion 1111 (i.e., the transverse direction of the chassis 10a). Since the supporting portion 1111 is mainly supported by the supporting section 11112, by setting the width of the supporting section 11112 to be larger than the width of the extending section 11111, the contact area between the rotating bracket 112 and the supporting section 11112 can be increased, thereby reducing the deformation of the supporting section 11112.

[0056] It is understood that the rotation support 112 can be any structure such as a support rod or a support plate that can be fixed to the support portion 1111 to provide support for the tray 20. In one embodiment, the rotation support 112 includes a fixed plate 1121, an articulated frame 1122, and a reinforcing rib 1123. The fixed plate 1121 extends along the second direction and is fixedly connected to the support section 11112. The articulated frame 1122 is vertically fixed to the fixed plate 1121. The reinforcing rib 1123 connects the fixed plate 1121 and the articulated frame 1122. One side of the tray 20 is hinged to the articulated frame 1122. Specifically, the fixed plate 1121 can increase the contact area between the rotating bracket 112 and the support segment 11112, and convert the point contact with the support segment 11112 into surface contact, thereby reducing the deformation of the support segment 11112. The articulated frame 1122 can be used for the tray 20 to be hinged, and the reinforcing ribs 1123 can strengthen the connection between the articulated frame 1122 and the fixed plate 1121, thereby reducing the deformation of the articulated frame 1122 and reducing the offset of the tray 20 along the lateral direction of the chassis 10a.

[0057] It is understandable that the fixing plate 1121 can be fixed to the support portion 1111 by any connection method such as welding, clamping, etc. In one embodiment, the fixing plate 1121 is fastened to the support portion 1111 by a threaded connection.

[0058] In this embodiment, Figure 6As shown, the fixed plate 1121 is provided with reinforced edges 11211 on both sides, the hinged frame 1122 is connected to one end of the fixed plate 1121, one side of the reinforcing rib 1123 is connected to the reinforced edge 11211, and the other side of the reinforcing rib 1123 is connected to the hinged frame 1122. Specifically, the reinforcing rib 1123 is connected to the reinforced edge 11211, so that part of the force of the hinged frame 1122 can be transferred to the reinforced edges 11211 on both sides of the fixed plate 1121, thereby reducing the deformation of the fixed plate 1121.

[0059] In this embodiment, Figure 6 As shown, a connecting strip 11212 is provided at one end of the fixing plate 1121 away from the hinge frame 1122 , and both ends of the connecting strip 11212 are respectively connected to the two reinforcing edges 11211 to reduce deformation of the reinforcing edges 11211 .

[0060] The support portion 1111 of the bottom support seat 11 of the embodiment of the present application is spaced apart from the bottom wall of the chassis 10a, and the support section 11112 of the support portion 1111 is widened, so that the force on the bottom wall of the chassis 10a is dispersed, thereby reducing the deformation of the bottom wall of the chassis 10a during the flipping of the tray 20. The reinforcing ribs 1123 can reduce the deformation of the hinged frame 1122 by strengthening the connection between the hinged frame 1122 and the fixed plate 1121. The reinforcing ribs 1123 can reduce the deformation of the fixed plate 1121 by connecting the reinforcing edges 11211 on both sides of the fixed plate 1121, thereby achieving the effect of reducing the deformation of the bottom wall of the chassis, and ultimately reducing the offset of the tray 20 when it rotates. The extension of the extension section 11111, the support section 11112 and the fixing plate 1121 in the second direction can limit the tray 20 to deflect only in the second direction (the width direction of the chassis 10a), so it is only necessary to correct the tray 20 along the second direction to facilitate the correction of the tray 20.

[0061] It is understandable that the tray 20 can be hinged to the bottom support seat 11 and the side support seat 12 at any position. For example, the tray 20 can be hinged to the bottom support seat 11 and the side support seat 12 through the bottom edge or the side edge.

[0062] In one embodiment, Figure 7 As shown, the tray 20 includes a tray body 22 and two support beams 23. The two support beams 23 are hinged to the bottom support base 11 and the side support base 12, respectively. The two sides of the tray body 22 are respectively mounted on the two support beams 23. Specifically, the tray 20 can be configured to arrange various components of the upper node through the tray body 22. The two support beams 23 on both sides of the tray body 22 can provide support for the tray body 22 and realize hinge connection with the bottom support base 11 and the side support base 12. Since the support beams 23 have high strength, they can provide high-strength support for the tray body 22, which can prevent the tray body 22 from deforming during the flipping process.

[0063] In this embodiment, Figure 7 As shown, enclosing edges 221 are provided on both sides of the tray body 22, and a connecting beam 222 is provided at one end of the tray body 22 close to the support 10, and the connecting beam 222 connects the enclosing edges 221 on both sides. A handle 223 is provided at one end of the tray body 22 away from the support 10, and the handle 223 can be used for holding, providing convenience for the flipping operation of the tray 20.

[0064] In this embodiment, the support beam 23 is fastened to the bottom of the disk body 22 by screws.

[0065] In order to realize the articulation of the support beam 23 with the bottom support seat 11 and the side support seat 12, in one embodiment, as shown in FIG. Figure 4 As shown, the bottom support seat 11 and the side support seat 12 are provided with a hinge rod 13 and an adjustment nut 14. The support beam 23 is sleeved on the hinge rod 13 and is hinged to the hinge frame 1122 and the side support seat 12 through the hinge rod 13. The adjustment nut 14 is threadedly connected to the hinge rod 13 and is configured to adjust the tightness of the hinge connection between the support beam 23, the hinge frame 1122 and the side support seat 12. Specifically, the support beam 23 can be hinged to the bottom support seat 11 and the side support seat 12 by being sleeved on the hinge rod 13. By controlling the tightness of the adjustment nut 14, the tightness of the support beam 23 can be adjusted, so that the tray 20 is in a loose state that can be rotated by manipulation and can hover at any position. The natural hovering of the tray 20 eliminates the need to set up an additional support structure to support the tray 20, thereby providing convenience for the maintenance of the server node.

[0066] In this embodiment, since the tray 20 is subjected to different load capacities when loaded with different types of devices, when the devices loaded on the tray 20 are changed, the corresponding tightness of the tray 20 also needs to be adjusted synchronously.

[0067] In this embodiment, when the tray 20 is in a free rotation state, the lateral restraint force it is subjected to is relatively small. Therefore, the tray 20 will not have a large lateral displacement in the free rotation state. When the tray 20 is subjected to the lateral locking force of the adjusting nut 14, the lateral restraint force it is subjected to is relatively large. Therefore, lateral displacement is likely to occur in this state. The greater the locking force, the greater the lateral displacement of the tray 20. In order to avoid excessive lateral displacement of the tray 20, the tightness of the adjusting bolt needs to be controlled within an appropriate range.

[0068] It is understandable that the deflection correction component 30 can be any driving component that can drive the tray 20 to shift laterally during the flipping process of the tray 20. For example, the deflection correction component 30 can be a limit frame fixed to the chassis 10a and extending toward the tray 20. If the tray 20 shifts toward the limit frame during the flipping process and exceeds the set lateral area, the tray 20 can be limited by the limit frame within the set lateral area. The deflection correction component 30 can also be a driving member and a push rod. If the tray 20 shifts out of the set lateral area during the flipping process, the driving member drives the push rod to push the tray 20, thereby controlling the tray 20 within the set lateral area. The deflection correction component 30 can also be a driving member and a hook. If the tray 20 shifts out of the set lateral area during the flipping process, the driving member drives the hook to pull the tray 20, thereby controlling the tray 20 within the set lateral area.

[0069] In order to realize the automatic control of the correction amount by the correction component 30, in one embodiment, as shown in FIG. Figure 2 and Figure 3 As shown, the correction component 30 includes an offset detection structure 31 and a correction structure 32. The offset detection structure 31 is configured to detect the lateral offset of the tray 20 along the second direction during the flipping process. The correction structure 32 is electrically connected to the offset detection structure 31 and is configured to correct the rotating tray 20 in the second direction according to the lateral offset detected by the offset detection structure 31, so as to limit the rotation of the tray 20 within a lateral area in the second direction.

[0070] Specifically, the offset detection structure 31 can detect the actual lateral offset of the pallet 20 during the flipping process. The offset detection structure 31 controls the correction amount of the correction structure 32 according to the lateral offset of the pallet 20, thereby realizing automatic control of the correction amount, thereby eliminating the need for manual measurement of the offset and correction amounts, and providing convenience for the operation of the flipping mechanism.

[0071] It is understandable that the offset detection structure 31 may be any detection structure capable of detecting the lateral offset of the tray 20 during its flipping process. For example, the offset detection structure 31 may be an infrared detector mounted on the chassis 10a.

[0072] In order to eliminate the influence of the rotation of the tray 20 on the detection of the offset, in one embodiment, as shown in FIG. Figure 8As shown, the offset detection structure 31 includes a detection probe 311 and a detection block 312. The detection probe 311 is mounted on the tray 20 and is used to generate a laser signal. The detection block 312 is disposed in the incident direction of the laser signal. The detection probe 311 is configured to detect the lateral offset of the tray 20 along the second direction according to the incident position of the laser signal entering the detection block 312. Specifically, the laser generated by the detection probe 311 is located within a vertical plane. Since the detection probe 311 is mounted on the tray 20, when the tray 20 deviates laterally in the second direction during flipping, it will cause the detection probe 311 to deviate laterally. The lateral offset of the detection probe 311 causes the laser generated by the detection probe 311 to deviate laterally in the second direction, causing the position of the laser beam irradiated on the detection block 312 in the second direction to change. The difference between the front and rear positions of the laser beam irradiated on the detection block 312 in the second direction is the lateral offset of the tray 20 during flipping, thereby achieving accurate measurement of the lateral offset of the tray 20 during flipping.

[0073] In this embodiment, since the lateral offset of the freely reversible tray 20 during its rotation is relatively small, the position where the laser irradiates the detection block 312 when the tray 20 is in the freely reversible state is used as the base point. Based on this, the steps for measuring the lateral offset of the tray 20 during its rotation are as follows: first, loosen the adjustment nut 14 to allow the tray 20 to rotate freely. The position where the laser irradiates the detection block 312 when the tray 20 is in the freely rotating state is denoted as c. Then, tighten the adjustment nut 14 until the tray 20 can hover. The tray 20 is then reversed in this state. The position where the laser irradiates the detection block 312 when the tray 20 is in this state is denoted as d. The lateral offset X of the tray 20 should satisfy X = dc.

[0074] In order to accurately obtain the incident position of the laser into the detection block 312, in one embodiment, as shown in FIG. Figure 9 As shown, the detection block 312 is divided into several neatly arranged laser entrance areas 3121, each laser entrance area 3121 forms a bright line area 31211 for the laser to pass through and a dark line area 31212 that is opaque. The detection probe 311 is configured to emit at least three lasers, and the irradiation position of the detection probe 311 is obtained according to the light transmittance of each laser.

[0075] Specifically, the laser entry areas 3121 are arranged neatly along the length and width of the chassis 10a, with the lasers spaced apart along the length of the chassis 10a. When a laser strikes a dark pattern area 31212, it is reflected. The reflected laser light is received by the detection probe 311 and converted into an electrical signal, representing a signal 1. A bright pattern area 31211 allows the laser light to pass through the block without reflection. If the detection probe 311 does not receive any reflected laser light, it represents a signal 0. Based on the difference in the combined 0 and 1 signals generated by each incident laser light, the detection probe 311 determines the position where the laser light entered the detection block 312.

[0076] It is understood that the width of each laser entry area 3121 can be adaptively set based on actual measurement accuracy. For example, the width of each laser entry area 3121 can be set to 0.1 mm. The position where the laser irradiates the detection block 312 when the tray 20 is flipped in the freely rotating state is denoted as c. The position where the laser irradiates the detection block 312 when the tray 20 is flipped in the hovering state is denoted as d. Therefore, the lateral offset of the tray 20, X (mm), = (dc) * 0.1.

[0077] It can be understood that each laser incident area 3121 can be configured as a bright line area 31211 or a dark line area 31212 to adapt to the row setting according to the number of lasers formed by the detection probe 311, and it is only necessary to make the combined signals formed by each laser incident area 3121 in each row in the second direction different.

[0078] In order to achieve precise control of the deflection amount of the tray 20, in one embodiment, as shown in FIG. Figure 2 and Figure 10 As shown, the correcting structure 32 includes a control member 321 and a correcting member 322. The correcting member 322 is arranged on the side of the tray 20. The side of the correcting member 322 close to the tray 20 is provided with an abutting surface 3221, and the abutting surface 3221 is located on the rotation path of the side of the tray 20. During the flipping process of the tray 20, the abutting surface 3221 can apply a driving force in the second direction to the side of the tray 20 by abutting with the side of the tray 20, thereby driving the tray 20 to move in the second direction. When the abutting surface 3221 is configured to be in the correcting position, the tray 20 is restricted to rotate within a lateral area in the second direction by applying a driving force in the second direction to the side of the rotating tray 20. The control member 321 is driven and connected to the correcting member 322, and is configured to drive the correcting member 322 according to the lateral offset detected by the offset detection structure 31, so that the abutting surface 3221 is in the correcting position.

[0079] Specifically, after each device is loaded on the tray 20, the actual lateral offset X of the tray 20 during the flipping process is first measured by the offset detection structure 31 through the above steps, and then the actual correction amount Z of the tray 20 is determined according to the offset Y allowed by the tray 20. After obtaining the correction amount Z, the correction amount Z is stored in the control module of the control component 321. The control component 321 accurately controls the correction component 322 according to the correction amount Z, so that the abutment surface 3221 of the correction component 322 is always maintained in the correction position and the position of the correction component 322 is kept stationary. During the flipping process of the tray 20, the edge of the tray 20 will abut against the abutment surface 3221, and the edge of the tray 20 is always in contact with the abutment surface 3221, and the abutment surface 3221 is used for correction. Under the correction of the abutment surface 3221, the tray 20 is always flipped in the lateral area where it will not touch the device, thereby providing convenience for the maintenance of the server node.

[0080] In this embodiment, when the chassis 10a is equipped with another type of node, the lateral offset of the tray 20 also changes due to the change in the weight of the node. To avoid friction and jamming problems, it is only necessary to follow the above steps to obtain a new lateral offset of the tray 20, and then redetermine the correction amount based on the lateral offset of the tray 20.

[0081] It can be understood that the cylinder can drive the correcting member 322 to move toward or away from the tray 20, so that the correcting member 322 is in the correcting position, and the control member 321 can be any driving component such as the cylinder that can drive the correcting member 322 to move horizontally.

[0082] To facilitate the arrangement of the control member 321, in one embodiment, as Figure 2 and Figure 10 As shown, the control member 321 includes a stepper motor, which is drivably connected to the correcting member 322 and is configured to drive the correcting member 322 to rotate toward or away from the tray 20, thereby positioning the correcting member 322 in the correcting position. Specifically, after obtaining the correcting amount, the stepper motor controls the correcting member 322 to rotate a predetermined angle toward or away from the tray 20 while maintaining the position of the tray 20. This allows the correcting member 322 to correct the tray 20 via the abutment surface 3221.

[0083] In this embodiment, Figure 10 As shown, the abutment surface 3221 includes an inclined plane 32211 and a curved surface 32212. The inclined plane 32211 extends to the top of the correcting member 322. The curved surface 32212 is connected to the inclined plane 32211 and extends to the bottom of the correcting member 322. The curved surface 32212 can slowly correct the tray 20 during the flipping process of the tray 20. After correction, the tray 20 will abut against the inclined plane 32211, thereby keeping it hovering.

[0084] In this embodiment, Figure 10 As shown, the deviation-correcting structure 32 further includes a base 323 . The base 323 can be fixedly connected to the bottom wall of the chassis 10 a , and the stepping motor is fixed to the base 323 .

[0085] In one embodiment, Figure 2 、 Figure 3 and Figure 7 As shown, the tray 20 is provided with a receiving opening 21 on its side. The receiving opening 21 is used to accommodate the end of the correcting member 322 in the correcting position. The bottom wall of the receiving opening 21 can abut against the correcting member 322 when the tray 20 rotates. Specifically, the receiving opening 21 is provided on the enclosed edge 221. By accommodating the end of the correcting member 322, the receiving opening 21 can reduce the height and space occupied by the correcting member 322, thereby facilitating the layout of the correcting structure 32 within the chassis 10a.

[0086] It can be understood that based on the offset of the tray 20, the correcting structure 32 can be set on one side or both sides of the tray 20, that is, if the tray 20 deviates on both sides during the rotation process, the correcting structure 32 is set on both sides of the tray 20 to correct the offset on any side; if only one side of the tray 20 deflects during the rotation process, the correcting structure 32 is set on the side of the tray 20 where the deflection occurs, and when the side deflects, the side is corrected.

[0087] In this embodiment, since one side of the tray 20 is hinged to the side wall of the chassis 10a through the side support seat 12, and the other side of the tray 20 is hinged to the bottom wall of the chassis 10a through the bottom support seat 11, based on the fact that the deformation of the base of the chassis 10a is much greater than the deformation of the side wall of the chassis 10a, the tray 20 will only undergo lateral displacement on the side hinged to the bottom support seat 11 during the flipping process. Therefore, the correction component 30 of this embodiment is arranged on the side of the tray 20 close to the bottom support seat 11, and only the side of the tray 20 hinged to the bottom support seat 11 needs to be corrected. Specifically, the correction structure 32 is arranged on the side of the tray 20 close to the bottom support seat 11. The correction structure 32 can be fixed to the bottom wall of the chassis 10a through the machine base 323. The detection probe 311 is fixed to the enclosing edge 221 of the side of the tray 20 close to the bottom support seat 11, and can emit at least 3 lasers to the bottom wall of the chassis 10a. The detection block 312 is arranged in the incident direction of the laser.

[0088] In this embodiment, Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 7As shown, the support beam 23 is hinged to one end of the bottom support seat 11 and the side support seat 12 and is provided with a first limiting protrusion 231, and the bottom support seat 11 and the side support seat 12 are provided with a second limiting protrusion 15, and the second limiting protrusion 15 extends toward the direction of the support beam 23. The first limiting protrusion 231 can be offset by the second limiting protrusion 15 through the rotation of the support beam 23 to limit the rotation of the support beam 23. Through the setting of the first limiting protrusion 231 and the second limiting protrusion 15, the flipping angle of the tray 20 can be limited, thereby preventing the tray 20 from detaching from the correcting member 322, so that the tray 20 is difficult to reset under the obstruction of the correcting member 322.

[0089] The embodiment of the present application further provides a server chassis, comprising a chassis and the aforementioned flip mechanism, wherein the support 10 of the flip mechanism is fixedly connected to the chassis. Specifically, the server chassis can be used to arrange the components of the lower node and the upper node through the chassis and the flip mechanism to form a server. When performing maintenance work on the lower node of the server, the upper node can be flipped through the tray 20 of the flip mechanism. During the flipping action, the flipped tray 20 can be corrected by the correction component 30, thereby preventing the tray 20 from touching the side components during the flipping process. This effectively solves the technical problem that the tray 20 is easily touched by other components in the chassis during the flipping process, causing friction and jamming, causing inconvenience to the flipping of the tray 20, and easily damaging components.

[0090] In some embodiments, the bottom support base 11 of the flip mechanism is fixedly connected to the bottom wall of the server chassis, the side support base 12 of the flip mechanism is fixedly connected to the side wall of the chassis, and the correction structure 32 of the flip mechanism is fixedly connected to the bottom wall of the chassis and is located on the side of the tray 20 close to the bottom support base 11. Specifically, by connecting one side of the flip mechanism to the side wall of the chassis and the other side to the bottom wall of the chassis, various sizes and types of devices can be accommodated between the tray 20 of the flip mechanism and the side wall of the chassis 10a. The correction structure 32 is arranged on the side of the tray 20 close to the bottom support base 11, and can correct the deviation of the tray 20 when the tray 20 is close to the bottom support base 11, thereby preventing the tray 20 from contacting other devices in the chassis during the flipping process.

[0091] The present application also provides a server comprising a server chassis and server nodes, at least some of which are disposed within the server chassis and within a tray 20 of the server chassis. Specifically, by configuring the server chassis, the server can implement a hierarchical layout of the nodes, achieving a compact layout of the server nodes while maintaining easy maintenance of the server nodes.

This article uses specific examples to illustrate the principles and implementation methods of this application. The description of the above embodiments is only intended to help understand the method and core ideas of this application.
