Abstract
Description
Technical Field
[0001] This application relates to the field of server technology, and in particular to a handle module, node chassis and server. Background Technology
[0002] Currently, with the rapid development of cloud computing, big data, and artificial intelligence technologies, data centers are placing higher demands on server performance, density, and maintainability. Multi-node servers, due to their efficient data processing capabilities, flexible scalability, and compact design, have become an important component of modern data centers. To optimize the maintenance efficiency of node chassis, various handle modules have traditionally been used. These handles, based on a single-sided stop-lock design, significantly reduce the force required for maintenance personnel to pull out and install node chassis. This design simplifies the operation process, allowing maintenance personnel to quickly and accurately pull out and install chassis even with high-density node chassis arrangements, reducing labor costs and improving work efficiency. Through a reasonable lever arm and locking structure, the handle modules help reduce connector wear and extend the overall lifespan of the server.
[0003] However, despite the convenience offered by existing handle modules, they face a significant problem in practical applications: they are prone to detachment during chassis transport or server operation due to vibration. Since most existing handle modules only engage on one side, the connection between the handle and chassis can become unstable or even completely unlock when the server experiences unexpected vibration or impact. This undoubtedly poses a major threat to the reliability of the entire system. If the handle detaches during vibration, it can cause the node chassis to slip out of the rack, damaging internal hardware, and interrupt normal server operation, resulting in unnecessary service interruptions and data loss. Furthermore, due to the assembly gaps typically existing between the node chassis and the outer chassis, existing handle designs are prone to misalignment when closing. This not only affects the smoothness of the handle's engagement but may also lead to incomplete engagement, further exacerbating the potential risks during transport. Utility Model Content

[0037] 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.
[0038] like Figures 1 to 10As shown, this application provides a handle module, including: a first connector 100, including a first connecting end 110 and a first snap-fit end 120, the first connecting end 110 being hinged to a node chassis, the first snap-fit end 120 being rotatably disposed around the first connecting end 110, the first snap-fit end 120 being provided with a first snap-fit portion 121 and a first limiting portion 122, one of the first snap-fit portion 121 and the first limiting portion 122 being disposed on the side of the first connector 100 near the node chassis, and the other being disposed on the side of the first connector 100 away from the node chassis; a second connector... The connector 200 includes a second connecting end 210 and a second snap-fit end 220. The second connecting end 210 is used to hinge with the node chassis. The second snap-fit end 220 is rotatably arranged around the second connecting end 210. The second snap-fit end 220 is provided with a second snap-fit portion 221 and a second limiting portion 222. One of the second snap-fit portion 221 and the second limiting portion 222 is arranged on the side of the second connector 200 near the node chassis, and the other is arranged on the side of the second connector 200 away from the node chassis. The second snap-fit portion 221 and the first snap-fit portion 121 are adapted to each other.
[0039] In this embodiment, when the handle module is in the locked state, the first latching part 121 and the second latching part 221 latch together, and the first limiting part 122 is used to limit and abut against the second limiting part 222; when the handle module is in the unlocked state, the first connecting member 100 and the second connecting member 200 separate.
[0040] By applying the technical solution of this embodiment, the provided handle module can effectively solve the technical problems of handles on node chassis easily unlocking and detaching during vibration, and handles not closing smoothly due to gaps between chassis. The key to this handle module lies in its unique dual-sided locking structure and limiting mechanism. By designing the first locking part 121 and the second locking part 221 on different sides and enabling them to lock into each other, combined with the limiting abutment of the first limiting part 122 and the second limiting part 222, it is ensured that the handle will not accidentally unlock under external force or vibration, significantly enhancing the stability of the handle and the reliability of the entire system. Simultaneously, the linkage mechanism between the first connecting member 100 and the first locking end 120, and between the second connecting member 200 and the second locking end 220, can overcome the gap problem between chassis, ensuring smoothness during handle closure and improving the user experience when operating the handle. When the handle module is locked, the precise engagement of the first latching part 121 and the second latching part 221, as well as the firm contact between the first limiting part 122 and the second limiting part 222, ensures a secure lock on the handle, maintaining the connection safety of the node chassis even in harsh transportation environments. When the handle module is unlocked, the first connecting part 100 and the second connecting part 200 separate, allowing users to easily disassemble and maintain the chassis, reducing operational difficulty and required force, and improving maintenance efficiency. This handle module is not only easy to operate, but also effectively prevents accidental unlocking of the handle in vibration environments through its unique double-sided latching design, overcomes the problem of uneven closure caused by gaps between chassis, and solves the problem of easy loosening of the handle module of the node chassis in related technologies.
[0041] In the above embodiment, when the handle module is in the unlocked state, at least a portion of the first connector 100 extends out of the front panel 820 of the node chassis to form a handle for gripping. The handle module is designed such that, when in the unlocked state, a portion of the first connector 100 extends out as a handle from the front panel 820 of the node chassis. This structure allows maintenance personnel to intuitively and conveniently find the grip point without having to fumble around in a confined space. This not only saves time and improves work efficiency but also avoids potential injuries or accidental damage to the chassis caused by searching for an improper grip point. When the handle is not needed, the first connector 100 can be retracted, reducing the space occupied by the chassis in the server rack and preventing the handle from becoming an obstacle when the chassis is closed or from being damaged by collisions with other objects during transportation.
[0042] like Figure 3As shown, specifically, the first latching portion 121 is a latching groove, the second latching portion 221 is a latching protrusion, the side of the first limiting portion 122 near the second limiting portion 222 forms a first limiting surface, and the side of the second limiting portion 222 near the first limiting portion 122 forms a second limiting surface; when the handle module is in the locked state, at least a portion of the first limiting surface is used to abut against at least a portion of the second limiting surface for limiting, and at least a portion of the latching protrusion extends into the latching groove so that the first connector 100 and the second connector 200 latch together.
[0043] In this embodiment, the first latching portion 121 of the handle module of the node chassis is designed as a latching groove, while the second latching portion 221 is a latching protrusion. A first limiting surface is formed on the side of the first limiting portion 122 near the second limiting portion 222, and a second limiting surface is formed on the side of the second limiting portion 222 near the first limiting portion 122. When the handle module is in the locked state, at least a portion of the first limiting surface abuts against at least a portion of the second limiting surface, while at least a portion of the latching protrusion extends into the latching groove, thereby achieving a secure latching connection between the first connector 100 and the second connector 200. This design ensures a stable connection between the rotating handle and the unlocking latch under vibration, effectively preventing unlocking and disengagement due to accidental vibration, and enhancing the reliability of the entire system. Furthermore, the abutment and limiting between the first and second limiting surfaces provides additional stability, making the handle less prone to loosening due to external interference in the locked state, further ensuring the safety of the node chassis during transportation. When the handle module is unlocked, the latching protrusion retracts from the latching slot, allowing the rotating handle to separate from the unlocking latch, facilitating smooth pulling and maintenance of the node chassis. In this way, this invention simplifies the disassembly and assembly process of the node chassis, improves maintenance efficiency, and reduces potential risks caused by improper design. When the handle module is engaged, the special structure of the first latching part 121 and the second latching part 221, along with the additional positioning provided by the first limiting part 122 and the second limiting part 222, ensures the smoothness of the handle during closure and the firmness of the engagement, avoiding problems caused by handle misalignment and improving the user experience. It also ensures the safety and stability of the high-density connector during insertion and removal from the node chassis.
[0044] Specifically, the handle module also includes a mounting base plate 300, which is used to be mounted on the node chassis. At least a portion of the mounting base plate 300 extends along the extension direction of the node chassis. A first connector 100 and a second connector 200 are provided on the mounting base plate 300, and the first connector 100 and the second connector 200 are spaced apart along the extension direction of the node chassis.
[0045] like Figure 8 , Figure 9As shown, in this embodiment, the handle module of the node chassis includes a mounting base plate 300. This mounting base plate 300 is positioned along the extension direction of the node chassis, and first connectors 100 and second connectors 200 are spaced apart on it. This layout not only provides a stable support base but also optimizes the connection between the handle module and the chassis side panel, enhancing the overall stability and reliability of the module. The spaced placement of the first connectors 100 and second connectors 200 ensures the balance between the rotating handle and the unlocking latch during movement, preventing structural deformation or damage due to excessive force on one side. The introduction of the mounting base plate 300 further simplifies the installation steps of the handle module, enabling accurate connection to the node chassis without complex positioning or adjustment, reducing assembly difficulty and time costs.
[0046] Furthermore, this structural design allows the handle module to be adapted to side panels of different widths. When the chassis height requirements change, the corresponding mounting base plate 300 can be replaced without re-molding, saving costs and improving the product's versatility and adaptability, thus demonstrating greater flexibility in practical applications.
[0047] Specifically, the second connector 200 is provided with a positioning member 230, which protrudes towards the side close to the mounting base plate 300. The mounting base plate 300 is provided with a positioning groove 310, and at least a portion of the positioning member 230 extends into the positioning groove 310 to limit the rotation angle of the second snap-fit end 220.
[0048] In the above embodiments, the positioning element 230 further optimizes the structural stability and operational precision of the handle module. The positioning element 230 protrudes towards the mounting base plate 300, designed to precisely match the positioning groove 310, effectively limiting the rotation range of the second locking end 220 and ensuring accurate engagement and secure locking between the rotating handle and the unlocking latch. This mechanism of limiting the rotation angle not only enhances the reliability and durability of the handle module during operation but also avoids the risk of unlocking latch dislocation due to excessive rotation or misoperation, significantly improving the safety of the entire system during transportation and use. Furthermore, the cooperation between the positioning element 230 and the positioning groove 310 helps users perceive clear positioning feedback during operation, improving the intuitiveness and ease of operation, thereby enhancing maintenance efficiency and user experience.
[0049] In this embodiment, the mating relationship between the positioning groove 310 and the positioning member 230 is crucial to ensuring the precise movement of the second connector 200 within its specific rotation path. The positioning member 230 is designed as a protruding structure, extending from the second connector 200 toward the mounting base 300, while a corresponding arc-shaped positioning groove 310 is provided on the mounting base 300. This arc-shaped positioning groove design has significant advantages compared to traditional straight or rectangular positioning grooves, especially in limiting the rotation angle of the second snap-fit end 220. When the second connector 200 rotates, the positioning member 230 slides and moves along the arc-shaped path of the positioning groove 310. The two end walls of the positioning groove 310 act as limiters; when the positioning member 230 rotates to either end of the positioning groove 310, it abuts against the groove wall at that end, thereby preventing the second connector 200 from continuing to rotate beyond a preset angle.
[0050] Specifically, the handle module also includes a first rotating shaft 400 and a first torsion spring 500. The first connecting member 100 is rotatably connected to the mounting base plate 300 via the first rotating shaft 400. The first torsion spring 500 is sleeved on the first rotating shaft 400. One end of the first torsion spring 500 is connected to the first connecting member 100, and the other end of the first torsion spring 500 is connected to the mounting base plate 300. When the handle module is switched from the locked state to the unlocked state, the first torsion spring 500 provides a rotational elastic force to the first latching end 120. The handle module also includes a second rotating shaft 600 and a second torsion spring 700. The second connecting member 200 is rotatably connected to the mounting base plate 300 via the second rotating shaft 600. The second torsion spring 700 is sleeved on the second rotating shaft 600. One end of the second torsion spring 700 is connected to the second connecting member 200, and the other end of the second torsion spring 700 is connected to the mounting base plate 300. When the handle module is switched from the locked state to the unlocked state, the second torsion spring 700 provides a rotational elastic force to the second latching end 220.
[0051] In this embodiment, the handle module integrates a first rotating shaft 400 and a first torsion spring 500, which together ensure that the first connector 100 can rotate elastically relative to the mounting base 300. Specifically, the first torsion spring 500 is sleeved on the first rotating shaft 400, and its two ends are respectively connected to the first connector 100 and the mounting base 300, thereby forming an elastic rotation mechanism. When the handle module is in the unlocked state, the first torsion spring 500 provides a rebound driving force for the first latching end 120, causing the first latching end 120 to quickly return to a predetermined position. At the same time, the handle module is also equipped with a second rotating shaft 600 and a second torsion spring 700, which are connected to the second connector 200 and the mounting base 300 in a similar manner, realizing the elastic rotational movement of the second latching end 220. This dual torsion spring drive mechanism not only simplifies the operation process, allowing users to easily switch the handle module between locked and unlocked states, but also ensures the accuracy and stability of the handle module's reset under various conditions, thereby improving the overall operating efficiency and user experience of the handle module. Furthermore, by precisely adjusting the torsion angle and force of the first torsion spring 500 and the second torsion spring 700, the mechanical properties of the handle module can be further optimized, ensuring reliability and durability under different usage environments.
[0052] Specifically, a first stop 320 is provided on the mounting base plate 300, the first stop 320 protrudes from the surface of the mounting base plate 300, and the first stop 320 is located at one end near the first connector 100. When the handle module is in the unlocked state, the first connector 100 contacts the first stop 320; and / or, a second stop 330 is provided on the mounting base plate 300, the second stop 330 protrudes from the surface of the mounting base plate 300, and the second stop 330 is located at both ends near the second connector 200. When the handle module is in the unlocked state, the second connector 200 contacts the second stop 330.
[0053] In this embodiment, a first stop 320 and a second stop 330 are provided on the mounting base 300, both of which protrude from the surface of the mounting base 300. The first stop 320 is located near the end of the first connector 100, while the second stop 330 is located near the other end of the second connector 200. When the handle module is in the unlocked state, i.e., when the rotating handle and the unlocking latch are separated, the first connector 100 contacts the first stop 320, and similarly, the second connector 200 contacts the second stop 330. The key function of this design is that it not only limits the range of movement of the connectors in the unlocked state but also ensures the stability of the handle module's position after unlocking. When the user needs to unlock the node chassis for maintenance or to pull it out, they only need to push the second latching end 220 of the second connector 200 upwards to unlock it. At this time, the first and second connectors are respectively limited by the stops.
[0054] Specifically, the first connector 100 also includes a first protrusion 101, which is disposed on the side of the first connector 110 away from the first snap-fit end 120. At least a portion of the first protrusion 101 extends toward the node chassis for contacting the mounting substrate 300.
[0055] In this embodiment, the first connector 100 further includes a first protrusion 101, which is located on the side of the first connecting end 110 away from the first snap-fit end 120 and extends at least partially toward the node chassis to facilitate contact with the mounting substrate 300. This design ensures that the first connector 100 can more securely engage with the surrounding structure during installation or fixing, enhancing the reliability and stability of the connection. The extension of the first protrusion 101 not only increases the contact area between the first connector 100 and the mounting substrate 300, thereby optimizing the force transmission path, but also effectively prevents loosening caused by external impacts or vibrations, which is crucial for the long-term operation of the equipment in complex environments.
[0056] Specifically, the second connector 200 also includes a second protrusion 201, which is disposed on the side of the second connector 200 near the second snap-fit end 220. At least a portion of the second protrusion 201 extends toward the node chassis for contact with the node chassis.
[0057] In this embodiment, the second connector 200 integrates a second protrusion 201, which is located near the second latching end 220 and extends at least partially toward the node chassis, designed to form an abutment relationship with the node chassis. This structure not only enhances the contact stability between the unlocking latch and the chassis sidewall but also optimizes the overall assembly process of the handle module. In practical applications, the protruding design of the second protrusion 201 allows the unlocking latch to more accurately align with the slot on the rotary handle during closing, ensuring accurate engagement even with slight assembly errors or chassis gaps, thus improving operational reliability and user experience. Furthermore, the abutment between the second protrusion 201 and the node chassis provides an additional physical lock to the handle module during chassis transportation or vibration, preventing accidental unlocking of the handle due to external impacts and further enhancing the overall mechanical safety of the device.
[0058] This application also provides a node chassis including the above-mentioned handle module. The node chassis includes a front panel 820 and a side panel 810. The node chassis includes at least one handle module, which is disposed on the side panel 810.
[0059] like Figures 11 to 13As shown, this application also provides a node chassis, which has a front panel 820 and a side panel 810, with at least one handle module mounted on the side panel 810. This arrangement allows users to utilize the handle module more effectively when removing or installing the node chassis, improving operational convenience and efficiency. By setting the handle module on the side panel 810, not only is it easier to pull out the node chassis, but the double-sided locking structure and limiting mechanism of the handle module further enhance the stability of the node chassis during transportation, avoiding accidental unlocking and loosening caused by vibration, and ensuring a reliable connection between the node chassis and the external chassis. In addition, the integrated design of the handle module and the node chassis optimizes the overall layout of the chassis, making maintenance and inspection of the chassis more convenient, reducing potential failures caused by improper handle design, and improving the user experience of the node chassis and the reliability of the entire system. When the handle module is in the locked state, the stability of the chassis is significantly improved, while in the unlocked state it is easy to operate, significantly reducing the difficulty of disassembling and assembling the node chassis.
[0060] In the embodiments of this application, the node chassis is provided with two handle modules, which are respectively disposed on the side plates 810 on both sides of the node chassis. In other embodiments, the handle modules may also be disposed on the top plate or the bottom plate of the node chassis.
[0061] like Figure 14 As shown, this application provides a server including the above-described node chassis. The server includes a housing 900, and the node chassis is detachably mounted on the housing 900. When the handle module is in the unlocked state, at least a portion of the first card connector 120 extends in a direction away from the housing 900.
[0062] This application also provides a server integrating the aforementioned handle module structure. The server includes a housing 900, and a node chassis is detachably mounted on the housing 900. When the handle module is in the unlocked state, a portion of the first latch end 120 is designed to extend away from the housing 900. This design allows for easy and rapid separation and reassembly of the node chassis from the housing without adding extra complex operations, greatly facilitating the maintenance and upgrade of internal server components. Especially when dealing with high-density server architectures, this handle module can provide sufficient space for necessary hardware adjustments while maintaining a compact structure, effectively reducing the technical difficulty of operating in confined spaces. Furthermore, the unique construction of this handle module ensures that the node chassis remains stably connected during server operation or movement, preventing data loss or other hardware damage risks due to accidental unlocking, thereby improving the operational reliability and security of the entire server system.
[0063] As can be seen from the above embodiments, this application has the following beneficial effects:
[0064] Efficient locking and unlocking mechanism:
[0065] The unique design of the locking and limiting parts of the first connector 100 and the second connector 200 enables simple and stable locking and unlocking functions. The engagement of the locking parts and the abutment of the limiting parts ensure the stability of the handle module in the locked state, while the separation action in the unlocked state is smooth and natural, greatly facilitating the operation of maintenance personnel and improving the efficiency and reliability of chassis pull-out.
[0066] Space utilization optimization:
[0067] The partial extension of the first connector 100 in the unlocked state and its folding in the locked state cleverly utilize the space of the front panel of the chassis, avoiding the handle occupying extra space when idle. This is extremely important in high-density server environments, as it helps to improve the overall layout flexibility and space utilization efficiency of the server.
[0068] Structural stability and operational safety:
[0069] The contact between the stop and the connector on the mounting base 300 effectively limits excessive movement of the connector in the unlocked state, enhancing structural stability. Simultaneously, the stop reduces accidental unlocking during operation, increasing operational safety.
[0070] Precise control of rotation angle:
[0071] The positioning member 230 on the second connector 200 and the positioning groove 310 on the mounting base plate 300 precisely limit the rotation angle of the second locking end 220, ensuring the accuracy and repeatability of the unlocking latch during operation, and avoiding mechanical failure or locking mechanism failure caused by excessive rotation.
[0072] Self-reset function:
[0073] The first torsion spring 500 and the second torsion spring 700 provided elastic restoring force to the connector when the handle module switches from the locked state to the unlocked state, realizing the automatic reset of the handle module, simplifying the operation process, reducing the workload of maintenance personnel, and reducing the damage to components that may be caused by manual reset.
[0074] Highly versatile and easy to maintain:
[0075] The adjustable design of the mounting base plate 300 allows the handle module to be adapted to node chassis and server architectures of different heights, improving its versatility and adaptability. This feature reduces maintenance costs caused by changes in equipment specifications, enabling the handle module to be widely used in various server systems.
[0076] Reduce the impact of vibration:
[0077] The first protrusion 101 and the second protrusion 201 abut against the mounting base plate 300 and the side plate 810 respectively, which enhances the rigidity of the handle in the locked state, effectively reduces the impact of vibration in the transportation or working environment on the handle, avoids accidental unlocking due to vibration, and ensures the overall operational stability and data security of the server.
[0078] Improve user experience:
[0079] The handle module in this application, with its simple design and excellent operational feedback, provides maintenance personnel with a superior feel and user experience. Whether locking or unlocking, the operation is smooth and natural, reducing uncertainty and complexity, thereby improving the overall operational efficiency of the server system and user satisfaction.
[0080] Easy to integrate and upgrade:
[0081] Integrating handle modules into node chassis and servers not only simplifies the overall structural design of the equipment but also provides a convenient upgrade path. Maintenance personnel or manufacturers can easily replace handle modules to adapt to new operational needs or perform repairs without making major modifications to the server's main structure.
[0082] In summary, the handle module of this application effectively solves the problems existing in the prior art through a series of innovative designs, such as complex operation, wasted space, and unstable structure. It greatly improves the maintenance efficiency and operational safety of node chassis and servers, while showing significant advantages in space utilization, vibration resistance, user experience, and integrated upgrades, demonstrating its practical value and forward-looking nature in the field of modern data center and server management.
