Description

Technical Field

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

[0002] Currently, with the increasing demand for convenient and efficient server equipment maintenance, server racks are typically designed as centralized solutions for power supply connections, liquid cooling connections, and high-density signal transmission in order to reduce power cables and conduits and improve signal transmission efficiency. This is especially true given the dominance of liquid cooling, which often includes liquid cooling connectors on the rack end. This transforms the server chassis installation process into a simple mating process between connectors on the rear of the server chassis and connectors on the rack end. This significantly increases the insertion and pulling forces between the connectors, causing considerable inconvenience for installing and removing server chassis.

[0003] To address these issues, existing technologies typically involve adding handles to the server chassis. Workers pull the handles to slide the chassis out of the rack, and the handles engage with the chassis after assembly. However, this connection method has low reliability; the handles can easily detach from the chassis when subjected to the reaction force of the connectors. This not only affects the normal installation of the server but may also cause equipment damage or personal injury. Utility Model Content

[0004] This application provides a chassis handle structure and a chassis to at least solve the problem of poor connection stability and easy detachment between the server chassis and the handle in the related art.

[0005] This application provides a chassis handle structure, including: two handle assemblies, each handle assembly including a handle, the handle including a pivot portion, an assist portion, and a first mating portion, the first mating portion being located at the end of the assist portion away from the pivot portion; the pivot portion being used for rotatable connection with the chassis body; when the handle rotates relative to the chassis body, the assist portion abuts against the chassis to form a fulcrum; a locking mechanism located between the two handle assemblies, the locking mechanism including a body and two locking components, the two locking components being arranged one-to-one with the two handle assemblies, each locking component including a locking structure and a first elastic structure, the locking structure being movably disposed on the body, the locking component having a locked state in which the locking structure is inserted into the first mating portion, and an unlocked state in which the locking structure is separated from the first mating portion; wherein, when the locking component is in the locked state, the first elastic structure is connected to the locking structure to apply an elastic force to the locking structure and push the locking structure to insert into the corresponding first mating portion.

[0006] Furthermore, each locking component also includes a guide post, on which at least a portion of the locking structure is fitted to slide along the extension direction of the guide post.

[0007] Furthermore, the first mating part is a first recess, and the locking structure has a locking protrusion and a first guide groove. The locking protrusion is used to extend into the first recess to limit and stop with the first recess. The body includes a first extension arm. In the process of switching between the locked state and the unlocked state, the first extension arm extends into the first guide groove and slidably engages with the first guide groove.

[0008] Furthermore, the locking structure includes a second extension arm, the body has a second guide groove, and the first elastic structure is located in the second guide groove; wherein, during the switching process between the locking mechanism and the unlocking state, the second extension arm extends into the second guide groove and slidably engages with the second guide groove.

[0009] Furthermore, the fulcrum includes a first sub-fulcrum, and the assisting part includes a first abutting part. When the handle is rotated to the first angle, the first abutting part abuts against the groove wall of the limiting groove of the cabinet to form the first sub-fulcrum. The handle is rotated from the first sub-fulcrum from the first angle to the second angle. When the handle is rotated to the second angle, the chassis body and the cabinet are in the installation state.

[0010] Furthermore, within the plane of the handle, the distance between the pivot and the first abutment is less than the distance between the pivot and the first mating part.

[0011] Furthermore, the fulcrum includes a second sub-fulcrum, and the assisting part also includes a second abutting part. When the handle is rotated to the third angle, the second abutting part abuts against the outer surface of the cabinet to form a second sub-fulcrum. The handle rotates from the second sub-fulcrum from the third angle to the fourth angle. When the handle is rotated to the fourth angle, the chassis body and the cabinet are in a disassembled state. The first abutting part and the second abutting part are circumferentially spaced around the pivot.

[0012] Furthermore, within the plane of the handle, the distance between the pivot and the second abutment is less than the distance between the pivot and the first mating part.

[0013] Furthermore, the handle assembly also includes: a second elastic structure disposed at the assist portion; when the locking component is in the locked state, the second elastic structure is in an energy storage state; when the locking component switches from the locked state to the unlocked state, the second elastic structure releases elastic potential energy and pops the handle assembly out, so that the second abutment portion abuts against the outer surface of the cabinet to form a second sub-support point.

[0014] This application also provides a chassis, including: a chassis body, on which a limiting structure is provided; a chassis handle structure, which is provided on the chassis body; when the locking mechanism of the chassis handle structure is in a locked state, the limiting structure is used to limit and stop the locking structure of the locking mechanism; wherein, the chassis handle structure is the chassis handle structure described above.

[0015] By applying the technical solution of this application, the combined use of the main body, locking structure, and first elastic structure in the locking mechanism ensures the stability of the handle in the locked state and the reliability of unlocking. The locking structure and the first mating part limit and stop, and the elastic force applied by the first elastic structure allows the locking structure to be firmly connected with the first mating part, avoiding the risk of accidental unlocking of the handle when the server chassis is under heavy load or affected by external forces. This solves the problem of poor connection stability and easy detachment between the server chassis and the handle in related technologies. At the same time, the handle assembly utilizes the lever principle. When the handle rotates relative to the chassis body, the assist part abuts against the cabinet to form a fulcrum. The above setting can amplify a small operating force and convert it into a larger pushing or pulling force, significantly reducing the physical burden on operators when installing or disassembling the server chassis and improving operating efficiency and convenience.

[0032] 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.

[0033] To address the issues of poor connection stability and easy detachment between server chassis and handles in related technologies, this application provides a chassis handle structure and a chassis.

[0034] like Figures 1 to 6As shown, this application provides a chassis handle structure, including two handle assemblies 10 and a locking mechanism 20. Each handle assembly 10 includes a handle 11, which includes a pivot portion 12, an assist portion 17, and a first mating portion 14. The first mating portion 14 is located at the end of the assist portion 17 away from the pivot portion 12. The pivot portion 12 is used for rotatably connecting with the chassis body 30. When the handle 11 rotates relative to the chassis body 30, the assist portion abuts against the chassis 40 to form a fulcrum. The locking mechanism 20 is located between the two handle assemblies 10. The locking mechanism 20 includes a body 22 and two locking components. The two locking components are arranged one-to-one with the two handle assemblies 10. Each locking component includes a locking structure 21 and a first elastic structure 23. The locking structure 21 is movably disposed on the body 22. The locking component has a locked state in which the locking structure 21 is inserted into the first mating portion 14, and an unlocked state in which the locking structure 21 is separated from the first mating portion 14. When the locking component is in the locked state, the first elastic structure 23 is connected to the locking structure 21 to apply an elastic force to the locking structure 21 and push the locking structure 21 to be inserted into the corresponding first mating part 14.

[0035] By applying the technical solution of this embodiment, the combined use of the body 22, locking structure 21, and first elastic structure 23 in the locking mechanism 20 ensures the stability of the handle 11 in the locked state and the reliability of unlocking. The locking structure 21 and the first mating part 14 limit and stop, and the elastic force applied by the first elastic structure 23 enables the locking structure 21 to be firmly connected with the first mating part 14, avoiding the risk of the handle 11 being accidentally unlocked when the server chassis is under heavy load or affected by external forces, thereby solving the problem of poor connection stability and easy detachment between the server chassis and the handle in related technologies. At the same time, the handle assembly 10 utilizes the lever principle. When the handle 11 rotates relative to the chassis body 30, the assisting part 17 abuts against the cabinet to form a fulcrum, and the contact position between the assisting part 17 and the cabinet 40 forms a force point. The above configuration can amplify the small operating force and convert it into a larger pushing or pulling force, significantly reducing the physical burden on the operator when installing or disassembling the server chassis and improving operating efficiency and convenience.

[0036] In this embodiment, each locking structure 21 independently locks or unlocks its corresponding handle assembly 10. Even if one locking structure fails to fully lock for some reason, the other locking structure can still maintain the locked state of the handle assembly, providing redundant security and enhancing the reliability and security of the entire system. Thus, by employing two spaced-apart handle assemblies 10 and corresponding independent locking structures 21, not only is operational stability and security improved, and spatial layout optimized, and operational procedures simplified, but a better ergonomic experience is also provided, along with enhanced mechanical strength and durability, facilitating maintenance and replacement. This provides strong technical support for the efficient management and safe operation of the server chassis.

[0037] Optionally, one of the locking structure 21 and the first mating part 14 is a first protrusion, and the other is a first recess. The first protrusion extends into the first recess and engages with it to lock the locking mechanism 20. In this way, when the locking mechanism 20 is locked, the first protrusion extends into the first recess and engages with it to prevent them from disengaging and affecting the locking stability of the locking mechanism 20. Furthermore, this arrangement allows for more flexible selection of the structures of the locking structure 21 and the first mating part 14 to meet different usage requirements and working conditions, and also improves the processing flexibility of the workers.

[0038] In this embodiment, the locking structure 21 is a first protrusion and the first mating part 14 is a first recess. The first protrusion extends into the first recess and is limited to fit with the first recess, so that the locking mechanism 20 is in a locked state.

[0039] like Figure 3 and Figure 4 As shown, the locking mechanism 20 also includes a guide post 24. At least a portion of the locking structure 21 is fitted onto the guide post 24 to slide along the extending direction of the guide post 24. Thus, during the sliding process of the locking structure 21 between the locked and unlocked states, the guide post 24 provides a precise path for the sliding of the locking structure 21, ensuring the stability and accuracy of the locking structure 21 during the locking and unlocking process.

[0040] In this embodiment, the first elastic structure 23 is a spring, which is sleeved on the guide post 24. This allows the spring to apply force along the axis of the guide post 24, ensuring the correct direction of the elastic force and making the movement of the locking structure 21 smoother, reducing friction and misalignment during movement. Furthermore, this design simplifies the structure of the first elastic structure 23, making it easier to manufacture and implement, thus reducing manufacturing costs and difficulty.

[0041] like Figure 3 and Figure 4 As shown, the first mating part 14 is a first recess, and the locking structure 21 has a locking protrusion and a first guide groove 211. The locking protrusion is used to extend into the first recess to limit and stop it. The body 22 includes a first extension arm 221. During the switching between the locked and unlocked states, the first extension arm 221 extends into the first guide groove 211 and slidably engages with it. Thus, during locking and unlocking, the sliding engagement between the locking protrusion and the first recess, and between the first extension arm 221 and the first guide groove 211, ensures the stability and safety of the handle assembly 10 in the locked state, preventing accidental opening of the handle 11 under external force. During unlocking, the sliding engagement between the first extension arm 221 and the first guide groove 211 allows for smooth control of the locking protrusion exiting the first recess, achieving precise control of the unlocking process and avoiding damage or operational difficulties that may be caused by forced unlocking.

[0042] like Figure 3 and Figure 4 As shown, the locking structure 21 includes a second extension arm 212, and the body 22 has a second guide groove 222. A first elastic structure 23 is located within the second guide groove 222. During the switching between the locked and unlocked states, the second extension arm 212 extends into the second guide groove 222 and slidably engages with it. This sliding engagement design between the second extension arm 212 and the second guide groove 222 ensures smooth and unobstructed movement of the locking structure from the locked state to the unlocked state, and vice versa, thereby reducing operational resistance and improving operational fluency and efficiency. Simultaneously, by placing the first elastic structure 23 within the second guide groove 222, the internal structure of the locking mechanism 20 becomes more compact, improving space utilization.

[0043] like Figures 2 to 6 As shown, the fulcrum includes a first sub-fulcrum, and the assisting part 17 includes a first abutment part 171. When the handle 11 is rotated to the first angle, the first abutment part 171 abuts against the groove wall of the limiting groove 41 of the cabinet 40 to form the first sub-fulcrum. The handle 11 rotates from the first sub-fulcrum from the first angle to the second angle. When the handle 11 is rotated to the second angle, the chassis body 30 and the cabinet 40 are in the installation state. In this way, the formation of the first sub-fulcrum allows the lever principle to be maximized during the rotation of the handle 11 from the first angle to the second angle. The operator only needs to apply a relatively small operating force, which can be converted into a large thrust through the rotation of the handle 11, helping the chassis body 30 overcome the connection resistance between it and the cabinet 40, achieving fast and labor-saving installation, and realizing the assisting function of the assisting part 17.

[0044] In this embodiment, the precise fit between the first abutment portion 171 and the groove wall of the limiting groove 41 forms the first sub-support point, which plays a core role in the mobile phone case structure. It not only achieves efficient force conversion and precise control, improving the degree of automation of operation, but also optimizes the spatial layout, enhances the sense of confirmation during operation, and ensures the safety and reliability of the installation process between the chassis body 30 and the cabinet 40.

[0045] Specifically, during the process of installing the chassis body 30 into the rack 40, the locking component is in the unlocked state and the handle 11 is at the first angle. The first abutment part 171 abuts against the groove wall of the limiting groove 41 to form the first sub-fulcrum. According to the lever principle, at this time, the part of the handle 11 located between the first mating part 14 and the first sub-fulcrum is the power arm, and the part of the handle 11 located between the first sub-fulcrum and the pivot part 12 is the resistance arm. When the first mating part 14 is rotated clockwise, it is equivalent to applying a force to the power arm. The resistance arm will also be subjected to a corresponding force, that is, the pivot part 12 will apply a force to the chassis body 30. Through this force, the chassis body 30 can be moved in the installation direction. In this way, the operating handle 11 is rotated from the first angle to the second angle. The handle 11 rotates around the first sub-fulcrum and forms a lever structure. Through the pivot part 12, a force is transmitted to the chassis body 30 to move towards the rack 40, thereby assisting in installing the chassis body 30 into the rack 40.

[0046] In this embodiment, within the plane of the handle 11, the distance between the pivot portion 12 and the first abutment portion 171 is less than the distance between the pivot portion 12 and the first mating portion 14. This arrangement ensures that the arm length of the power arm is greater than the arm length of the resistance arm, thereby saving effort. When a smaller force is applied to the first mating portion 14, the pivot portion 12 can obtain a larger force, making the installation of the chassis body 30 easier.

[0047] like Figures 2 to 6As shown, the fulcrum includes a second sub-fulcrum, and the assisting part 17 also includes a second abutment part 172. When the handle 11 is rotated to the third angle, the second abutment part 172 abuts against the outer surface of the cabinet 40 to form the second sub-fulcrum. The handle 11 rotates from the second sub-fulcrum from the third angle to the fourth angle. When the handle 11 is rotated to the fourth angle, the chassis body 30 and the cabinet 40 are in a disassembled state. The first abutment part 171 and the second abutment part 172 are circumferentially spaced around the pivot part 12. In this way, the formation of the second sub-fulcrum maximizes the use of the lever principle during the rotation of the handle 11 from the third angle to the fourth angle. The operator only needs to apply a relatively small operating force, which can be converted into a large thrust through the rotation of the handle 11, to help the chassis body 30 overcome the connection force between it and the cabinet 40, achieving quick and effortless disassembly and realizing the assisting function of the assisting part 17. Meanwhile, the first contact portion 171 and the second contact portion 172 are arranged circumferentially around the pivot portion 12, which not only ensures that the handle 11 can form the necessary fulcrum at different angles, but also optimizes the structural layout of the handle assembly and maintains the compactness of the handle structure, which is crucial for the tight spatial layout between the chassis body 30 and the cabinet 40.

[0048] In this embodiment, the formation of the second sub-support point enables the transfer of force from the first sub-support point to the second sub-support point, ensuring precise control of the point of application and direction of force during disassembly. This force point transfer mechanism improves operational accuracy and avoids disassembly difficulties or equipment damage caused by inaccurate force application. Simultaneously, by using the formation of the second sub-support point to aid disassembly, it avoids mechanical wear and malfunctions caused by prolonged application of force to a single point, extending the overall service life of the handle assembly and the chassis body 30, and reducing maintenance costs and failure rates.

[0049] Specifically, when the chassis body 30 needs to be removed from the cabinet 40, the locking assembly is locked and the handle 11 is at the third angle. The second abutment part 172 abuts against the outer surface of the cabinet 40 to form a second sub-fulcrum. According to the lever principle, at this time, the part of the handle 11 located between the first mating part 14 and the second sub-fulcrum is the power arm, and the part of the handle 11 located between the second sub-fulcrum and the pivot part 12 is the resistance arm. When the first mating part 14 is rotated counterclockwise, it is equivalent to applying a force to the power arm. The resistance arm will also be subjected to a corresponding force, that is, the pivot part 12 will apply a force to the chassis body 30. Through this force, the chassis body 30 can be moved in the removal direction. In this way, the operating handle 11 is rotated from the third angle to the fourth angle. The handle 11 rotates around the second sub-fulcrum and forms a lever structure. Through the pivot part 12, the force of movement away from the cabinet 40 is transmitted to the chassis body 30, thereby providing assistance in removing the chassis body 30 from the cabinet 40.

[0050] In this embodiment, within the plane of the handle 11, the distance between the pivot portion 12 and the second abutment portion 172 is less than the distance between the pivot portion 12 and the first mating portion 14. This arrangement ensures that the arm length of the power arm is greater than the arm length of the resistance arm, thereby saving effort. When a smaller force is applied to the first mating portion 14, the pivot portion 12 can obtain a larger force, making the installation of the chassis body 30 easier.

[0051] like Figures 2 to 4 As shown, the handle assembly 10 also includes a second elastic structure 15. The second elastic structure 15 is located at the assist portion 17. When the locking component is in the locked state, the second elastic structure 15 is in an energy-storing state. When the locking component switches from the locked state to the unlocked state, the second elastic structure 15 releases its elastic potential energy and ejects the handle assembly 10, causing the second abutment portion 172 to abut against the outer surface of the cabinet 40 to form a second sub-fulcrum. Thus, when the locking component is in the locked state, the second elastic structure 15 is in an energy-storing state; once the locking component switches to the unlocked state, the second elastic structure 15 quickly releases its stored elastic potential energy, automatically pushing the handle 11 to rotate away from the chassis body 30, rapidly adjusting the position of the fulcrum to the initial state. This automatic reset function significantly reduces the operator's waiting time and the steps of manually adjusting the handle position, significantly improving the efficiency of server chassis installation and removal.

[0052] In this embodiment, as the locking component switches to the unlocked state, the release of the second elastic structure 15 provides obvious tactile feedback, allowing the operator to intuitively feel the action of resetting the handle, enhancing the sense of operation confirmation, ensuring the operator's accurate execution in each step, and reducing operational errors.

[0053] Optionally, the second elastic structure 15 is a compression spring.

[0054] like Figure 3 and Figure 4As shown, the handle 11 is provided with a second mating part 111, which is used to mate with a third mating part 31 provided on the chassis body 30. One of the second mating parts 111 and the third mating part 31 is a second protrusion, and the other is a second recess. When the locking mechanism 20 is in the locked state, the second protrusion extends into the second recess and engages with it. Thus, when the locking mechanism 20 is in the locked state, the aforementioned arrangement of the second mating parts 111 and the third mating part 31 increases the contact area between the handle 11 and the chassis body 30, thereby improving the connection stability between the handle 11 and the chassis body 30. At the same time, this arrangement allows for more flexible selection of the structure of the second mating parts 111 and the third mating part 31 to meet different usage requirements and working conditions, and also improves the processing flexibility of the operator.

[0055] In this embodiment, the second mating part 111 is a second recess, and the third mating part 31 is a second protrusion. When the locking mechanism 20 is in the locked state, the second protrusion extends into the second recess and engages with it. Thus, when the locking mechanism 20 is in the locked state, the second protrusion extending into the second recess and engaging with it forms a mechanical locking mechanism, ensuring a secure connection between the handle 11 and the chassis body 30. This design prevents the handle from loosening or falling off even when the server chassis is subjected to significant external forces (such as vibrations during transportation or impacts during handling), improving the overall structural stability and safety.

[0056] Optionally, there may be one second mating part 111, or there may be multiple second mating parts 111, with the multiple second mating parts 111 spaced apart along the extension direction of the handle 11. In this way, the above arrangement makes the selection of the number of second mating parts 111 more flexible to meet different usage needs and working conditions, and also improves the processing flexibility of the operator.

[0057] Optionally, there may be one third mating part 31, or there may be multiple third mating parts 31, with each of the multiple third mating parts 31 corresponding to a multiple of the second mating parts 111. This arrangement allows for greater flexibility in selecting the number of third mating parts 31 to meet different usage requirements and working conditions, and also improves the processing flexibility for workers.

[0058] like Figure 4 As shown, the chassis handle structure also includes a cover plate 60, which is detachably mounted on the body 22.

[0059] like Figure 1 , Figure 4 as well as Figure 6As shown, this application also provides a chassis, including a chassis body 30 and a chassis handle structure 50. The chassis body 30 is provided with a limiting structure 32 and a third mating part 31. The chassis handle structure 50 is disposed on the chassis body 30; when the locking mechanism 20 of the chassis handle structure 50 is in the locked state, the limiting structure 32 is used to limit and stop the locking structure 21 of the locking mechanism 20. The chassis handle structure 50 is the chassis handle structure described above.

[0060] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0061] The combined use of the main body, locking structure, and first elastic structure in the locking mechanism ensures the stability of the handle in the locked state and the reliability of unlocking. The locking structure and the first mating part limit and stop, and the elastic force applied by the first elastic structure ensures that the locking structure can firmly engage with the first mating part, avoiding the risk of accidental unlocking of the handle when the server chassis is under heavy load or affected by external forces. This solves the problem of poor connection stability and easy detachment between the server chassis and the handle in related technologies. Simultaneously, the handle assembly utilizes the lever principle. When the handle rotates relative to the chassis body, the assisting part abuts against the chassis to form a fulcrum. This design amplifies a small operating force, converting it into a larger pushing or pulling force, significantly reducing the physical burden on operators when installing or disassembling the server chassis and improving operational efficiency and convenience.

[0062] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
