Description

Technical Field

[0001] This utility model relates to the field of server chassis technology, specifically a modular server chassis. Background Technology

[0002] A server, as a high-performance computer device, is specifically designed to provide data, resources, and various services to clients on a network. It enables information sharing between different hardware and software, supporting a variety of critical applications, including website hosting, file storage, database management, email services, and application execution. Typically equipped with high-performance processors, large-capacity memory, and high-speed network interfaces, servers can operate stably for extended periods to handle the concurrent access demands of a large number of users. Depending on their functionality, servers can be categorized into various types, such as web servers, database servers, and file servers, and have become a core infrastructure of modern internet and enterprise information systems.

[0003] In terms of structure, current server chassis are typically divided into functional modules such as hard drive mounting areas, fan mounting areas, and motherboard and power supply mounting areas. However, critical components such as fans, motherboards, and power supplies are still primarily secured with screws. This traditional mechanical connection method is cumbersome and inefficient during server assembly, routine maintenance, and component replacement. Utility Model Content

[0013] Furthermore, the bottom of the chassis body is symmetrically provided with several raised bumps, and the raised bumps are hollow, with their tops abutting against the bottom of the housing frame.

[0014] Furthermore, both locking structures include an extension plate and a limiting plate spaced apart on the housing body. The limiting plate is provided with a locking post. The extension plate is rotatably connected to a connector via a stud. The other end of the connector is rotatably connected to an automatic reset locking mechanism. The automatic reset locking mechanism can engage and lock with the locking post. The connector is also provided with a limiting protrusion. The limiting protrusion can be inserted into a limiting hole on the chassis, and its length is less than the length of the limiting hole.

[0015] Furthermore, the automatic reset locking mechanism includes a rotating handle. The rotating handle has a connecting groove at one end of the connector. The end of the connector extends into the connecting groove and has a rotating hole in the vertical direction at its end that is rotatably connected to the rotating handle. A stud is inserted through the rotating hole. The rotating handle has a groove that cooperates with the locking stud for hooking and locking the locking stud.

The main control area has a partition (Part 1) with housings on both sides to support the motherboard, hard drive, and other main control functional modules. After the two housings are pushed in, their locking structures engage with corresponding limit holes (Part 1) for quick and easy fixation. The heat dissipation area has multiple partitions (Part 2), and fan compartments can be pushed between adjacent partitions. During the pushing process, the locking structures on these partitions automatically engage with the limit holes (Part 2) to automatically lock the fan compartments. This allows for tool-free quick installation and removal of both housings and fan compartments. Assembly, maintenance, and component replacement do not require opening the chassis cover, simplifying the operation process and improving installation and maintenance efficiency.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0039] Please refer to Figure 1-15 ;

[0040] A modular server chassis includes a chassis body 1, with a main control area and a heat dissipation area at its two ends. The main control area has a partition 3, and two mounting brackets 2 are placed on either side of the partition 3. The mounting brackets 2 are used to support the motherboard, hard drive, and other main control functional modules. Limiting holes 7 are provided on both the partition 3 and one side wall of the chassis body 1. Each mounting bracket 2 has a locking structure 6 that engages with the corresponding limiting hole 7. When installing the mounting bracket 2, it can be pushed into the chassis body 1 along the partition 3 until it is fully inserted. Once in place, the locking structure 6 aligns with the corresponding limiting hole 7. Then, by manually operating the locking structure 6, it is locked in place with the limiting hole 7, thus achieving quick fixation of the mounting bracket 2. The heat dissipation area is provided with several partitions 4 at intervals. Fan compartments 9 are placed between adjacent partitions. Each partition 4 has a limiting hole 41, and each fan compartment 9 has a locking structure 91 that engages with the corresponding limiting hole 41. When installing the fan compartment 9, it can be pushed into the chassis body 1 along the partition 4. During this process, the locking structure 91 automatically engages with the limiting hole 41, achieving automatic locking of the fan compartment 9, enabling tool-free quick installation and improving assembly and maintenance efficiency. A power supply compartment 8 is provided on one side of the heat dissipation area for housing the power supply. It should be noted that a wiring area is provided between the main control area and the heat dissipation area for routing and managing cables.

[0041] In this embodiment, both locking structures 6 include an extension plate 61 and a limiting plate 62 spaced apart on the receiving frame 2. The limiting plate 62 is provided with a locking post 63. The extension plate 61 is rotatably connected to a connector 64 via a stud 67. The other end of the stud 67 is threadedly connected to a nut. The engagement of the nut and the stud 67 is used to prevent the connector 64 from disengaging along the free end of the stud 67, while allowing the connector 64 to rotate freely around the stud 67. The other end of the connector 64 is rotatably connected to an automatic reset locking mechanism 65 that engages with the locking post 63. When the automatic reset locking mechanism 65 engages with the locking post 63, it can limit the rotation of the connector 64, preventing it from rotating. The connector 64 is provided with a limiting protrusion 66 for insertion into a limiting hole 7. The length of the limiting protrusion 66 is less than the length of the limiting hole 7, allowing it a certain amount of room to move within the limiting hole 7, so that the limiting protrusion 66 can be rotatably inserted into the limiting hole 7.

[0042] When the housing 2 is fully pushed into the chassis body 1, rotate the connector 64 toward the housing 2. As the connector 64 rotates, the limiting protrusion 66 on it gradually inserts into the limiting hole 7. When the connector 64 is rotated to its final position, the limiting protrusion 66 is fully inserted into the limiting hole 7. Then, manually rotate the automatic reset locking mechanism 65 to make it engage with the locking post 63. At this time, the connector 64 is locked by the locking post 63 and cannot rotate away from the housing 2. At the same time, because the limiting protrusion 66 is inserted into the limiting hole 7 and blocked by the chassis body 1, This restricts the movement of the housing frame 2, thereby enabling quick installation between the housing frame 2 and the chassis body 1. When it is necessary to disassemble the housing frame 2, first rotate the automatic reset locking mechanism 65 to disengage it from the locking post 63, releasing the rotational constraint on the connector 64. Then, rotate the connector 64 in the opposite direction, causing the limiting protrusion 66 to gradually exit from the limiting hole 7. When the limiting protrusion 66 is completely disengaged from the limiting hole 7, the housing frame 2 is no longer constrained and can slide out of the chassis body 1 along the opening direction, completing the quick disassembly. The entire installation and disassembly process is simple to operate, requiring no screws or tools, thus improving maintenance efficiency.

[0043] The automatic reset locking mechanism 65 includes a rotating handle 651. One end of the rotating handle 651 is located on the connector 64 and has a connecting groove 652. One end of the connector 64 extends into the connecting groove 652 and has a rotating hole 653 in a vertical direction at its end, communicating with the rotating handle 651. A stud 654 passes through the rotating hole 653, and the other end of the stud 654 is threaded with a nut, thereby rotatably mounting the rotating handle 651 onto the connector 64 and preventing it from falling off. The rotating handle 651 has a groove 655 on one side of the locking post 63, and the inner contour shape of the groove 655 is adapted to the outer periphery of the locking post 63. A torsion spring 656 is installed inside the connecting groove 652. The torsion spring 656 has an extension end 657 and an extension end 658 at its two ends. Extension end 657 is parallel to the connecting member 64 and abuts against the side wall of the connecting member 64 away from the groove 655. Extension end 658 abuts against the corresponding inner wall of the connecting groove 652. Through the abutting action of these two extension ends, the torsion spring 656 generates an elastic preload, causing the rotating handle 651 to always have a tendency to automatically rotate back to its initial position. It should be noted that... Figure 9As shown, in the initial state, the rotating handle 651 and the connector 64 are in a straight alignment. Specifically, in the initial state, the side wall of the connecting groove 652 near the groove 655 abuts against the side wall of the connector 64 on the corresponding side, restricting the rotating handle 651 from rotating in the direction of the receiving frame 2. Meanwhile, the side wall of the connecting groove 652 away from the groove 655 has a certain amount of room for movement, allowing the rotating handle 651 to rotate in the direction away from the receiving frame 2. Therefore, when the connector 64 is rotated to the locked position, the rotating handle 651 is rotated so that the opening of the groove 655 faces the locking post 63. The torsion spring 656 is twisted and stores elastic potential energy. At this time, the connector 64 is rotated again, and the groove 655 can be engaged with the outer periphery of the locking post 63. Then the connector 64 and the rotating handle 651 are released, the torsion spring 656 releases elastic potential energy, and drives the rotating handle 651 to automatically rotate back to reset. When the rotating handle 651 and the connector 64 are in a straight and aligned state, the side wall of the connecting groove 652 near the groove 655 abuts against the side wall of the corresponding side of the connector 64, restricting the rotating handle 651 from rotating in the direction of the receiving frame 2, so that the connector 64 and the rotating handle 651 remain in this state. At this time, the groove 655 hooks the locking post 63. When the receiving frame 2 is directly withdrawn, the limiting hole 7 blocks the limiting protrusion 66 from moving outward, causing the limiting protrusion 66 to abut against the inner wall of the limiting hole 7, resulting in an outward rotation tendency of the connector 64. At this time, due to the engagement between the locking post 63 and the groove 655, the rotating handle 651 will have a tendency to rotate in the direction of the receiving frame 2. The side wall of the connecting groove 652 near the groove 655 is already pressed against the corresponding side wall of the connector 64, causing the rotating handle 651 to be unable to rotate, thereby preventing the connector 64 from rotating and preventing the receiving frame 2 from being directly pulled out.

[0044] Considering that the housing 2 is located inside the chassis body 1 after full installation, and it is not convenient to directly pull it out, a second limiting protrusion 659 is provided on the side of the connector 64 located on the first limiting protrusion 66. The second limiting protrusion 659 is spaced apart from the first limiting protrusion 66. When the housing 2 is installed in place, the second limiting protrusion 659 is located on the outside of the chassis body 1 and close to the chassis body 1. During disassembly, after the automatic reset locking mechanism 65 disengages from the locking post 63, the connector 64 is rotated away from the housing frame 2. At this time, the second limiting protrusion 659 rotates synchronously. When the connector 64 rotates to a certain angle, the second limiting protrusion 659 contacts the end of the chassis body 1 and forms a fulcrum. If the rotational force is continued to be applied, the second limiting protrusion 659 will use this contact point as a fulcrum to apply an outward pushing force to the housing frame 2, thereby gradually pushing the entire housing frame 2 out of the chassis body 1, so that its end is exposed outside the chassis body 1, which is convenient for subsequent manual grasping and pulling out of the housing frame 2, thus facilitating the disassembly operation.

[0045] In this embodiment, the second locking structure 91 includes slots 92 spaced apart on one side of the fan compartment 9. The two slots 92 communicate with the corresponding limiting holes 41 on the partition 4 of the chassis body 1 after installation. An elastic piece 93 is fixedly installed inside the fan compartment 9. The elastic piece 93 is located on one side of the slots 92, with one end fixedly connected to the fan compartment 9, and the other end having two locking blocks 94 spaced apart. The two locking blocks 94 pass through the corresponding slots 92 and can extend into the limiting holes 41 of the partition 4 to achieve locking and positioning. A limiting port 95 is provided on the side of the fan compartment 9 facing the outside of the chassis body 1. A lever 96 protrudes from the limiting port 95 at the end of the elastic piece 93 located at the locking block 94. The lever 96 is exposed for easy manual operation by maintenance personnel. By levering the lever 96, the elastic piece 93 can be deformed, causing the locking block 94 to disengage from the limiting hole 41, thereby achieving quick disassembly of the fan compartment 9. Preferably, the side of the locking block 94 facing the inside of the chassis body 1 is provided with a guide slope. During the process of pushing the fan compartment 9 in, the guide slope first contacts the front end of the second partition 4. Under the continuous pushing force, the guide slope is squeezed, forcing the locking block 94 to retract into the fan compartment 9. At this time, the elastic sheet 93 undergoes elastic deformation and stores energy. When the fan compartment 9 continues to be pushed to the predetermined position and the slot 92 is completely aligned with the second limiting hole 41, the locking block 94 is no longer squeezed by the second partition 4. The elastic sheet 93 returns to its original shape under the elastic force, causing the locking block 94 to pop out and automatically insert into the second limiting hole 41, thereby realizing the automatic locking of the fan compartment 9. The fan compartment 9 cannot be directly pulled out, which improves the disassembly and assembly efficiency of the fan compartment 9.

[0046] By setting up independent main control area and heat dissipation area inside the chassis body 1, and configuring push-in housings 2 and fan compartments 9 with locking structures in each area, efficient installation and maintenance of key functional modules are achieved. The main control area has a partition 3, with housings 2 arranged on both sides to support the motherboard, hard drive, and other main control functional modules. After the two housings 2 are pushed into place, the locking structures 6 on them engage with the corresponding limit holes 7 to lock them in place, achieving quick fixation. The heat dissipation area has multiple partitions 4, and fan compartments 9 can be pushed in between adjacent partitions. The locking structures 91 on them automatically engage with the limit holes 41 during the pushing process, completing the automatic locking of the fan compartments 9. This allows both the housings 2 and fan compartments 9 to support tool-free quick installation and removal. Assembly, maintenance, and component replacement do not require opening the chassis cover, simplifying the operation process and improving the efficiency of installation and maintenance.

[0047] In this embodiment, a baffle 5 is provided at the end of the partition 3 in the main control area. The baffle 5 is arranged horizontally, and its two sides contact the inner walls of the two sides of the chassis body 1 respectively. The baffle 5 is used to limit the maximum stroke of the housing frame 2 when it is pushed into the chassis body 1 to prevent it from being pushed too far. A positioning post 51 is symmetrically provided on one side of the housing frame 2 on the baffle 5. The housing frame 2 is provided with positioning holes 21 for the corresponding positioning post 51 to be inserted. When the housing frame 2 is fully pushed into the installation position, the positioning post 51 is inserted into the corresponding positioning hole 21 to achieve axial positioning of the housing frame 2 and ensure its accurate position. A conical surface is provided on one end of the positioning post 51 of the housing frame 2. The conical surface plays a good guiding role in the positioning hole 21 during the process of pushing the housing frame 2 into the chassis body 1, guiding the positioning post 51 to be smoothly inserted into the positioning hole 21, improving the convenience of installation. A rubber washer 52 is sleeved on the positioning post 51. One side of the rubber washer 52 abuts against the baffle 5, and the other side abuts against the housing frame 2. By utilizing the elastic cushioning properties of the rubber gasket 52, the impact force can be absorbed during the pushing of the housing 2, reducing the collision between it and the baffle 5 and avoiding structural damage.

[0048] In this embodiment, the bottom of the chassis body 1 is symmetrically provided with several raised bumps 11, each with a hollow structure. The top of each bump abuts against the bottom of the housing frame 2. This structural design enhances the structural strength of the chassis body 1's bottom, reduces overall weight through the hollow structure, and provides uniform support after the housing frame 2 is installed, preventing excessive localized stress. Furthermore, the raised bumps 11 elevate the housing frame 2, allowing airflow to circulate in the gap between the bottom of the housing frame 2 and the bottom of the chassis body 1, thus improving the overall heat dissipation effect.

[0049] In this embodiment, two adjacent partitions 4 are symmetrically provided with limiting plates 42. The two limiting plates 42 are located at the end of the heat dissipation area and are used to limit the depth of the fan compartment 9 being pushed in.

[0050] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
