The flipping mechanism includes a support, a tray, and a correction component. The tray is hinged to the support and can rotate around the support in a first direction. The correction component is configured to drive the tray to move in a second direction perpendicular to the first direction. The server is provided with a chassis and a flipping mechanism. The server nodes can be arranged in layers on the chassis and the tray of the server flipping structure.

Description

Technical Field

[0001] This application relates to the field of server technology, and in particular to a server flipping mechanism, server chassis, and server. Background Technology

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

[0003] In related technologies, when the flipping mechanism performs the flipping action, the flipping part is prone to lateral displacement relative to the chassis, which makes it easy for the flipping part to come into contact with other components inside the chassis, making it difficult to complete the flipping action and causing inconvenience to server maintenance. Summary of the Invention

[0004] This application provides a flipping mechanism, a server chassis, and a server to at least solve the problem in the related art that the flipping mechanism is prone to contacting other components inside the chassis during the flipping process, making it difficult to complete the flipping action.

[0005] This application provides a flipping mechanism, including:

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

[0007] The tray is hinged to the support and is capable of rotating about the support in a first direction;

[0008] The correction component is configured to drive the pallet to move along a second direction perpendicular to the first direction, thereby restricting the pallet from rotating within a lateral region in the second direction.

[0009] This application also provides a server chassis, including:

[0010] Box;

[0011] A flipping mechanism, wherein the support of the flipping mechanism is fixedly connected to the housing.

[0012] This application also provides a server, including:

[0013] Server chassis;

[0014] The server nodes, at least some of which are located in the chassis of the server enclosure and the tray of the server enclosure.

[0015] Through this application, since the server is equipped with a chassis and a flipping mechanism, the server nodes can be arranged in layers on the chassis and the trays of the server flipping structure. When performing maintenance work on the server nodes arranged in the chassis, it is only necessary to flip the tray of the flipping mechanism to expose the server nodes in the chassis, so that maintenance of the server nodes in the chassis can be performed. Since the flipping mechanism is equipped with a correction component, the correction component can correct the tray during the tray flipping process, so that the tray is always within the range that it will not touch other components in the chassis during the flipping process. Therefore, it can effectively solve the technical problem that the flipping mechanism is prone to contact with other components in the chassis during the flipping process, and achieve the technical effect of facilitating the maintenance of server nodes.

[0034] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] As server architectures become increasingly complex, server chassis often incorporate flip-top structures to accommodate sufficient components within a compact chassis while maintaining high maintainability. These flip-top structures house the lower nodes and the upper nodes, allowing for maintenance without removing the server from the chassis.

[0036] In related technologies, 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. The two sides of the tray are hinged to the side wall 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 wall of the chassis 10a, making it difficult to configure taller components at the lower nodes. Therefore, this type of flip structure 20a has significant limitations and a narrow range of applications.

[0037] To maximize the placement of components within the limited space of the chassis 10a, the tray of the flip structure 20a can be configured in another way: the width of the tray is less than the width of the chassis 10a, allowing components taller than the tray to be placed between the tray 20 and the side walls of the chassis 10a. This type of flip structure 20a tray has two assembly methods: one where both sides of the tray are hinged to the bottom wall of the chassis 10a, and the other assembly method 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, this assembly method, where both sides of the chassis 10a are hinged to the bottom wall, results in an excessively narrow space between the tray and the side wall of the chassis 10a, limiting the types of devices that can be installed. To increase the width of the space between the tray and the side wall of the chassis 10a, allowing for the accommodation of more types of devices, the current common assembly method is to hinge one side of the tray to the side wall of the chassis 10a, while the other side is hinged to the bottom wall of the chassis 10a.

[0038] The problem with hinged trays on one side to the side wall of chassis 10a and the other side to the bottom wall of chassis 10a is that the stiffness of the bottom wall of chassis 10a is much less than that of the side wall. Since the hinge support on the bottom wall of chassis 10a exerts a large torque on the bottom wall, the deformation of the bottom wall is much greater than that of the side wall. This results in significant deformation of the bottom wall, increasing the amount of sway between the hinge support and the bottom wall of chassis 10a, making the hinge support prone to fatigue damage. Furthermore, it causes a large displacement of the hinge support located on the bottom wall of chassis 10a. In contrast, the side wall of chassis 10a has greater stiffness, resulting in smaller displacement of the hinge support at the side wall. Therefore, there is a displacement difference between the two hinge supports. The difference in deformation between the side walls and bottom walls of the chassis 10a, as well as the displacement difference between the hinge supports of the side walls and bottom walls, will cause the pallet to easily deform laterally during the flipping process. Since various components with lower nodes are arranged on the side of the pallet, the pallet is prone to contact with the components on the side during lateral displacement, causing friction and jamming, which makes it inconvenient to flip the pallet and can easily damage the components.

[0039] To address the problem that the tray of the aforementioned flipping structure 20a is prone to lateral displacement during flipping, easily colliding with side components, causing friction and jamming, inconveniencing the flipping of the tray, and easily damaging the components, this application provides a flipping mechanism. The flipping mechanism corrects the deviation of the flipped tray during the flipping action, thereby preventing the tray from colliding with side components during the flipping process. This effectively solves the technical problem that the flipping mechanism is prone to colliding with other components inside the chassis 10a during the flipping process, causing friction and jamming, inconveniencing the flipping of the tray, and easily damaging the components.

[0040] It should be noted that the flipping mechanism described in this application is used in, but not limited to, servers, etc., and can also be applied to any other device platform with limited space. For ease of explanation, this application only uses the application of the flipping mechanism in a server as an example. The principle of the flipping mechanism applied in other devices with limited space is essentially the same as that applied in a server, and will not be described in detail here.

[0041] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0042] To better understand this application, the following is combined with... Figures 2 to 10 The technical solution of this application is described in detail below:

[0043] like Figure 2 and Figure 3 As shown, the flipping mechanism provided in this embodiment includes a support 10 and a tray 20. The support 10 is fixedly connected to the server chassis, and the tray 20 is hinged to the support 10, allowing it to rotate around the support 10 in a first direction. Specifically, the flipping mechanism can be fixed to the chassis 10a via the support 10. The tray 20, through its hinge with the support 10, can be flipped relative to the chassis 10a via the support 10. Nodes can be arranged on both the bottom wall of the chassis 10a and the tray 20 to achieve layered arrangement of nodes. Nodes arranged on the bottom wall of the chassis 10a are defined as lower nodes, and 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), it can be moved away from the lower node, exposing the lower node, which facilitates the maintenance of the lower node. This achieves a compact layout of 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 flipping mechanism is installed on the chassis 10a, the transverse direction of the chassis 10a is defined as the second direction (…). Figure 2 In the first direction (a), 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, such as 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 along a second direction perpendicular to the first direction, and restrict the tray 20 from rotating within a lateral region in the second direction. Specifically, the correction component 30 can correct the tray 20 during the flipping process, ensuring that the tray 20 is always within a range that will not touch other components inside the chassis. By setting the correction component 30, the flipping mechanism can restrict the tray 20 to always be within a limited lateral region during flipping. Within this region, the side of the tray 20 will not touch other components in the chassis 10a, thereby effectively solving the technical problem of easy contact between the flipping mechanism and other components inside the chassis 10a during the flipping process, and facilitating the maintenance of server nodes.

[0047] Understandably, the lateral range in this embodiment is the area within which the tray 20 will not touch other components of the chassis 10a during the flipping process. This range depends on the distance between the side of the tray 20 and the nearest component, defined as Y. The tray 20 is allowed to shift laterally within the range of 0-Y. That is, if the lateral shift of the tray 20 during the flipping process is less than or equal to Y, the tray 20 will not touch the component during the flipping process; if the lateral shift of the tray 20 during the flipping process is greater than Y, the tray 20 will touch the component during the flipping process. The function of the correction component 30 is to control the lateral shift of the tray 20 within Y during the flipping process by correcting the lateral shift of the tray 20. If the lateral shift of the tray 20 during the flipping process is denoted as X, then 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] Understandably, the support 10 can be any structure that can be fixed to the chassis 10a and hinged to the tray 20.

[0049] Understandably, the support 10 can be fixed to any part of the chassis 10a, as long as it allows the tray 20 to be hinged and rotated relative to the chassis 10a. For example, the support 10 can be fixed only to the bottom or side wall of the chassis 10a, so that the tray 20 is hinged to the chassis 10a only through the bottom or side wall. The support 10 can also be fixed to both the bottom and side walls of the chassis 10a simultaneously, thus allowing the tray 20 to be hinged to both the bottom and side walls of the chassis 10a at the same time.

[0050] In one embodiment, to maximize the space between the tray 20 and the side wall of the chassis 10a, a portion of the support 10 is fixedly connected to the side wall of the chassis 10a, and another portion is fixed to the bottom wall of the chassis 10a. This allows the tray 20 to be hinged to the side wall of the chassis 10a fixed to the bottom wall, forming a larger accommodating space between the tray 20 and the side wall of the chassis 10a. This space can accommodate various different devices, thereby maximizing the applicability of the server flip structure 20a.

[0051] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the support 10 in this embodiment includes a bottom support 11 and a side support 12. The bottom support 11 is fixedly connected to the bottom wall of the server chassis, and the side support 12 is fixedly connected to the side wall of the server chassis. The two sides of the tray 20 are hinged to the bottom support 11 and the side support 12, respectively. The bottom support 11 allows the support 10 to be fixedly connected to the bottom wall of the chassis 10a, and the side support 12 allows the support 10 to be fixedly connected to the side wall of the chassis 10a. By hinged to the bottom support 11 and the side support 12, the tray 20 can be arranged with one side on the side wall of the chassis 10a and the other side on the bottom wall of the chassis 10a. This arrangement maximizes the space between the tray 20 and the side wall of the chassis 10a, allowing the space between the tray 20 and the side wall of the chassis 10a to accommodate the assembly of various types of devices, thereby expanding the applicability of the flipping mechanism.

[0052] In this embodiment, the support 10 is fixed to the bottom wall and side wall of the chassis 10a by the bottom support 11 and the side support 12 respectively, which causes the tray 20 to easily shift laterally in the lateral direction of the chassis 10a during the flipping process, and collide with the components on the side of the tray 20.

[0053] To reduce the deformation of the bottom wall of the chassis 10a during the flipping process of the tray 20, in one embodiment, such as Figure 4As shown, the bottom support 11 includes a reinforcing crossbeam 111 and a transfer bracket 112. The reinforcing crossbeam 111 includes a support portion 1111 and a fixing portion 1112 disposed on both sides of the support portion 1111. A groove 1113 is formed between the fixing portion 1112 and the support portion 1111. The fixing portion 1112 is used to fix to the bottom wall of the server chassis. The support portion 1111 can be spaced from the bottom wall of the server chassis through the groove 1113. Specifically, the bottom support 11 is fixed to the housing by the reinforcing beam 111, and the transfer bracket 112 supports the tray 20 and is hinged to the tray 20. Since the reinforcing beam 111 includes a support part 1111 and a fixing part 1112 provided on both sides of the support part 1111, the reinforcing beam 111 can be fixed to the bottom wall of the housing 10a by the fixing parts 1112 on both sides. Since a groove 1113 is formed between the fixing part 1112 and the support part 1111, the support part 1111 can be spaced from the bottom wall of the housing 10a, so that the force of the reinforcing beam 111 can be transmitted to the bottom wall of the housing 10a through the two sides, so that the transfer bracket 112 is not directly connected to the bottom wall of the housing 10a, thereby reducing the deformation of the bottom wall.

[0054] Understandably, the fixing part 1112 can be fixed to the bottom wall of the chassis 10a by means of welding, snap-fit, or other connection methods, as long as it can achieve stability on the bottom wall of the chassis 10a. In one embodiment, the fixing part 1112 is provided with a plurality of threaded mounting holes, and the fixing part 1112 is fastened to the bottom wall of the chassis 10a by threaded connectors.

[0055] To reduce the deformation of the bottom wall of the chassis 10a during the flipping process of the tray 20, in one embodiment, such as 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 a 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 transfer bracket 112 is fixed to the support section 11112. Specifically, the support section 11112 can be used to fix the transfer bracket 112 and provide support for the tray 20. The extension section 11111 extends along the second direction (the width direction of the chassis 10a), which increases 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, reducing the deformation of the bottom wall of the chassis 10a. The extension section 11111 can also guide the offset of the tray 20, so that the tray 20 will only offset in the extension direction of the extension section 11111 of the support portion 1111 (i.e., the lateral direction of the chassis 10a). Since the support section 1111 is mainly supported by the support section 11112, by setting the width of the support section 11112 to be greater than the width of the extension section 11111, the contact area between the supply bracket 112 and the support section 11112 can be increased, and the deformation of the support section 11112 can be reduced.

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

[0057] Understandably, the fixing plate 1121 can be fixed to the support portion 1111 by any connection method such as welding or snap-fit. In one embodiment, the fixing plate 1121 is fastened to the support portion 1111 by a threaded connector.

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

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

[0060] In this embodiment, the support portion 1111 of the bottom support base 11, through its spacing from the bottom wall of the chassis 10a and the widening of the support section 11112 of the support portion 1111, can distribute the force on the bottom wall of the chassis and reduce the deformation of the bottom wall of the chassis 10a during the flipping of the tray 20. The reinforcing rib 1123, by strengthening the connection between the hinge frame 1122 and the fixing plate 1121, can reduce the deformation of the hinge frame 1122. The reinforcing rib 1123, by connecting the reinforcing edges 11211 on both sides of the fixing plate 1121, can reduce the deformation of the fixing plate 1121, thereby achieving the effect of reducing the deformation of the bottom wall of the chassis and ultimately reducing the offset when the tray 20 rotates. The extension of the extension section 11111, the support section 11112, and the fixing plate 1121 in the second direction can limit the pallet 20 to only shift in the second direction (the width direction of the chassis 10a). Therefore, it is only necessary to correct the pallet 20 along the second direction to facilitate the correction of the pallet 20.

[0061] Understandably, the pallet 20 can be hinged to the bottom support 11 and the side support 12 at any point. For example, the pallet 20 can be hinged to the bottom support 11 and the side support 12 via the bottom edge or the side edge.

[0062] In one embodiment, such as 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 equipped with various components of the upper node through the configured 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 achieve hinged 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 and prevent the tray body 22 from deforming during the flipping process.

[0063] In this embodiment, as Figure 7 As shown, the tray 22 has enclosing edges 221 on both sides, and a connecting beam 222 is provided at the end of the tray 22 near the support 10. The connecting beam 222 connects the enclosing edges 221 on both sides. A handle 223 is provided at the end of the tray 22 away from the support 10. The handle 223 can be gripped and provides convenience for flipping and operating the tray 20.

[0064] In this embodiment, the support beam 23 is fastened to the bottom of the disc body 22 by a threaded fitting.

[0065] To achieve the hinged connection between the support beam 23 and the bottom support 11 and the side support 12, in one embodiment, such as Figure 4 As shown, the bottom support 11 and the side support 12 are equipped with hinge rods 13 and adjusting nuts 14. The support beam 23 is sleeved on the hinge rod 13 and is hinged to the hinge frame 1122 and the side support 12 via the hinge rod 13. The adjusting nut 14 is threaded to the hinge rod 13 and is configured to adjust the tightness of the hinge between the support beam 23 and the hinge frame 1122 and the side support 12. Specifically, the support beam 23 can be hinged to the bottom support 11 and the side support 12 by being sleeved on the hinge rod 13. By controlling the tightness of the adjusting nut 14, the tightness of the support beam 23 can be adjusted, so that the tray 20 is in a state that can be rotated by manipulation and can be suspended in any position. By allowing the tray 20 to suspend naturally, there is no need to set up an additional support structure to support the tray 20, thereby facilitating the maintenance of the server node.

[0066] In this embodiment, since the load-bearing capacity of the tray 20 is different when different types of devices are loaded, the tightness of the tray 20 needs to be adjusted accordingly when the devices loaded on the tray 20 change.

[0067] In this embodiment, when the tray 20 is in a free-rotating state, the lateral constraint force it receives is small. Therefore, the tray 20 will not experience a large lateral offset when it is in a free-rotating state. When the tray 20 is subjected to the lateral locking force of the adjusting nut 14, the lateral constraint force it receives is large. Therefore, it is easy for lateral offset to occur in this state. Moreover, the greater the locking force, the greater the lateral offset of the tray 20. In order to avoid the lateral offset of the tray 20 being too large, the tightness of the adjusting bolt needs to be controlled within a suitable range.

[0068] Understandably, the alignment correction component 30 can be any driving component capable of driving the pallet 20 to shift laterally during the flipping process. For example, the alignment correction component 30 can be a limiting frame fixed to the chassis 10a and extending toward the pallet 20. If the pallet 20 shifts toward the limiting frame during the flipping process and exceeds the set lateral range, the pallet 20 can be limited within the set lateral range by the limiting frame. The alignment correction component 30 can also be a driving element and a push rod. If the pallet 20 shifts out of the set lateral range during the flipping process, the driving element drives the push rod to push the pallet 20, controlling the pallet 20 within the set lateral range. The alignment correction component 30 can also be a driving element and a hook. If the pallet 20 shifts out of the set lateral range during the flipping process, the driving element drives the hook to pull the pallet 20, controlling the pallet 20 within the set lateral range.

[0069] To achieve automated control of the correction amount by the correction component 30, in one embodiment, such as 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 in 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 rotation of the tray 20 in the second direction according to the lateral offset detected by the offset detection structure 31, thereby restricting the tray 20 to rotate within a lateral region in the second direction.

[0070] Specifically, the offset detection structure 31 can detect the actual lateral offset during the flipping process of the pallet 20. Based on the lateral offset of the pallet 20, the offset detection structure 31 controls the correction amount of the correction structure 32, thereby realizing the automatic control of the correction amount. This eliminates the need for manual measurement of the offset and correction amount, and provides convenience for the operation of the flipping mechanism.

[0071] Understandably, the offset detection structure 31 can be any detection structure capable of detecting the lateral offset during the flipping process of the tray 20. For example, the offset detection structure 31 can be an infrared detector installed in the chassis 10a.

[0072] To eliminate the influence of tray 20 rotation on offset detection, in one embodiment, such as 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 positioned in the incident direction of the laser signal. The detection probe 311 is positioned at the incident point of the laser signal into the detection block 312 to detect the lateral offset of the tray 20 along the second direction. Specifically, the laser generated by the detection probe 311 is located in a vertical plane. Since the detection probe 311 is mounted on the tray 20, when the tray 20 shifts laterally along the second direction during the flipping process, it will cause the detection probe 311 to shift laterally. The lateral shift of the detection probe 311 will cause the laser generated by the detection probe 311 to shift laterally in the second direction, causing the position of the laser irradiating the detection block 312 in the second direction to change. The difference between the front and rear positions of the laser irradiating the detection block 312 in the second direction is the lateral offset of the tray 20 during the flipping process, thereby achieving accurate measurement of the lateral offset of the tray 20 during the flipping process.

[0073] In this embodiment, since the lateral offset of the tray 20 during the flipping process is small when it is in a freely flippable state, the position where the laser of the freely flipped tray 20 illuminates the detection block 312 is used as the base point. Based on this, the measurement steps for the lateral offset of the tray 20 during rotation are as follows: First, loosen the adjusting nut 14 to allow the tray 20 to rotate freely, and record the position where the laser illuminates the detection block 312 when the tray 20 is flipped in the freely rotating state as c. Then, adjust the tightness of the adjusting nut 14 until the tray 20 can be suspended, and then flip the tray 20 in this state, and record the position where the laser illuminates the detection block 312 when the tray 20 is flipped in this state as d. Then, the lateral offset X of the tray 20 should satisfy X=dc.

[0074] To accurately determine the incident position of the laser incident on the detection block 312, in one embodiment, such as Figure 9 As shown, the detection block 312 is divided into several neatly arranged laser injection areas 3121. Each laser injection area 3121 forms a bright fringe area 31211 that can be transmitted by laser light and a dark fringe 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 transmission of each laser.

[0075] Specifically, the laser incident areas 3121 are neatly arranged along the length and width of the chassis 10a, with each laser spaced apart along the length of the chassis 10a. When a laser irradiates a dark fringe area 31212, it is reflected. The reflected laser is received by the detection probe 311 and converted into an electrical signal, representing signal 1. The bright fringe area 31211 allows the laser to pass through the block without reflection. When the detection probe 311 does not receive the reflected laser, it represents signal 0. The detection probe 311 determines the position of the laser entering the detection block 312 based on the different 0 and 1 combination signals formed by each incident laser.

[0076] Understandably, the width of each laser injection zone 3121 can be adaptively set according to the actual measurement accuracy. For example, the width of each laser injection zone 3121 can be set to 0.1 mm. Let c be the position where the laser irradiates the detection block 312 when the tray 20 is flipped in a free-rotation state. Let d be the position where the laser irradiates the detection block 312 when the tray 20 is flipped in a hovering state. Then, the lateral offset X (mm) of the tray 20 = (dc) * 0.1.

[0077] Understandably, the configuration of each laser injection area 3121 as a bright fringe area 31211 or a dark fringe area 31212 can be adapted to the number of lasers formed by the detection probe 311. It is only necessary to ensure that the combined signals formed by each laser irradiating each row of laser injection areas 3121 in the second direction are different.

[0078] To achieve precise control of the deflection of the pallet 20, in one embodiment, such as Figure 2 and Figure 10 As shown, the correction structure 32 includes a control element 321 and a correction element 322. The correction element 322 is disposed on the side of the tray 20. The side of the correction element 322 near the tray 20 is provided with an abutment surface 3221. The abutment surface 3221 is located on the rotation path of the side of the tray 20. During the flipping process of the tray 20, the abutment surface 3221 can apply a driving force in the second direction to the side of the tray 20 by abutting against the side of the tray 20, thereby driving the tray 20 to move in the second direction. When the abutment surface 3221 is configured in the correction position, the driving force in the second direction applied to the side of the rotating tray 20 restricts the tray 20 to rotate within a lateral region in the second direction. The control element 321 is drivenly connected to the correction element 322 and is configured to drive the correction element 322 according to the lateral offset detected by the offset detection structure 31, so that the abutment surface 3221 is in the correction position.

[0079] Specifically, after each device is loaded onto the tray 20, the actual lateral offset X during the tray 20 flipping process is measured by the offset detection structure 31 through the above steps. Then, based on the allowable offset Y of the tray 20, the actual correction amount Z of the tray 20 is determined. After obtaining the correction amount Z, the correction amount Z is stored in the control module of the control unit 321. The control unit 321 precisely controls the correction component 322 according to the correction amount Z, so that the contact surface 3221 of the correction component 322 is always kept in the correction position and the position of the correction component 322 remains unchanged. During the flipping process of the tray 20, the edge of the tray 20 will abut against the contact surface 3221. The edge of the tray 20 is always in contact with the contact surface 3221, and the correction is performed by the contact surface 3221. Under the correction of the contact surface 3221, the tray 20 is always flipped in a lateral area that will not touch the device, thereby facilitating 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 changes due to the change in node weight. To avoid friction and jamming problems, it is only necessary to obtain the new lateral offset of the tray 20 according to the above steps, and then redetermine the correction amount based on the lateral offset of the tray 20.

[0081] Understandably, the cylinder can drive the correction component 322 to move towards or away from the tray 20, thereby placing the correction component 322 in the correction position. The control component 321 can be any driving component such as a cylinder that can drive the correction component 322 to translate.

[0082] To facilitate the placement of the control component 321, in one embodiment, such as Figure 2 and Figure 10 As shown, the control unit 321 includes a stepper motor, which is driven and connected to the correction component 322. The stepper motor is configured to drive the correction component 322 to rotate towards or away from the tray 20, thereby positioning the correction component 322 in a correction position. Specifically, after acquiring the correction amount, the stepper motor controls the correction component 322 to rotate a certain angle towards or away from the tray 20, while keeping the tray 20 stationary. This allows the correction component 322 to correct the tray 20 via the contact surface 3221.

[0083] In this embodiment, as Figure 10 As shown, the contact surface 3221 includes an inclined plane 32211 and an arc-shaped surface 32212. The inclined plane 32211 extends to the top of the correction member 322, and the arc-shaped surface 32212 connects to the inclined plane 32211 and extends to the bottom of the correction member 322. The arc-shaped surface 32212 can slowly correct the tray 20 during the flipping process. After correction, the tray 20 will contact the inclined plane 32211, thereby keeping it suspended.

[0084] In this embodiment, as Figure 10 As shown, the correction structure 32 also includes a base 323, which can be fixedly connected to the bottom wall of the chassis 10a, and the stepper motor is fixed to the base 323.

[0085] In one embodiment, such as Figure 2 , Figure 3 and Figure 7 As shown, a receiving opening 21 is provided on the side of the tray 20. The receiving opening 21 is used to receive the end of the correction component 322 in the correction position. The bottom wall of the receiving opening 21 can abut against the correction component 322 by rotating the tray 20. Specifically, the receiving opening 21 is provided on the enclosing edge 221. By receiving the end of the correction component 322, the receiving opening 21 can reduce the height of the correction component 322 and the space occupation rate, which facilitates the layout of the correction structure 32 in the chassis 10a.

[0086] Understandably, based on the offset of the pallet 20, the correction structure 32 can be set on one or both sides of the pallet 20. That is, if both sides of the pallet 20 are offset during the rotation, the correction structure 32 is set on both sides of the pallet 20 to correct the offset on either side. If only one side of the pallet 20 is offset during the rotation, the correction structure 32 is set on the side of the pallet 20 that is offset, and when that side is offset, it corrects the offset on that side.

[0087] In this embodiment, since one side of the tray 20 is hinged to the side wall of the chassis 10a via the side support 12, and the other side of the tray 20 is hinged to the bottom wall of the chassis 10a via the bottom support 11, and the deformation of the chassis 10a base is much greater than the deformation of the side wall of the chassis 10a, the tray 20 will only shift laterally on the side hinged to the bottom support 11 during the flipping process. Therefore, the correction component 30 in this embodiment is set on the side of the tray 20 near the bottom support 11, and only the side of the tray 20 hinged to the bottom support 11 needs to be corrected. Specifically, the correction structure 32 is set on the side of the tray 20 near the bottom support 11. The correction structure 32 can be fixed to the bottom wall of the chassis 10a via the base 323. The detection probe 311 is fixed to the enclosure edge 221 on the side of the tray 20 near the bottom support 11, and can emit at least 3 lasers to the bottom wall of the chassis 10a. The detection block 312 is set in the incident direction of the laser.

[0088] In this embodiment, as 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. The bottom support seat 11 and the side support seat 12 are provided with a second limiting protrusion 15. The second limiting protrusion 15 extends toward the support beam 23. The first limiting protrusion 231 can abut against the second limiting protrusion 15 by the rotation of the support beam 23, so as to limit the rotation of the support beam 23. By setting 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 disengaging from the correction member 322, so that the tray 20 is difficult to reset under the obstruction of the correction member 322.

[0089] This application embodiment also provides a server chassis, including a chassis body and the aforementioned flipping mechanism, with the support 10 of the flipping mechanism fixedly connected to the chassis body. Specifically, the server chassis can be used to arrange the components of the lower and upper nodes to form a server through the chassis body and the flipping mechanism. When performing maintenance work on the lower node of the server, the upper node can be flipped through the tray 20 of the flipping mechanism. During the flipping action, the 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 prone to touching other components in the chassis during the flipping process, causing friction and jamming, which makes the flipping of the tray 20 inconvenient and easily damages the components.

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

[0091] This application also provides a server, including a server chassis and server nodes, with at least some of the server nodes disposed in the chassis housing and the server chassis tray 20. Specifically, by configuring the server chassis, the server can achieve a layered deployment of nodes, realizing a compact layout of server nodes without hindering the maintenance of the server nodes.

The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of this application.
