Description

Technical Field

[0001] The utility model belongs to the technical field of server packaging, in particular to a communication buffer damping structure and a server packaging structure. Background Art

[0002] A server is a high-performance computer system that provides services and resources to other computers or devices. It has powerful computing power, storage capacity, and stable operating performance, and can handle large numbers of data requests and concurrent connections. Servers can be divided into rack servers, tower servers, blade servers, etc. according to their structural form. Rack servers are servers designed according to unified standards and can be installed in standard cabinets. They have relatively fixed width and height dimensions. The width of a 19-inch chassis is 447mm. The height dimension is expressed in Us, with each U being 44.45mm high. Considering the rack assembly requirements, the height of a 1U server is generally 43mm, and that of a 2U server is 87mm.

[0003] With the development of artificial intelligence, AI servers are occupying an increasing market share. To meet the computing power, RAM, and high-speed storage requirements of AI tasks, AI servers typically require a large number of functional units, such as GPUs, TPUs, memory, cooling systems, and storage systems. As a result, AI servers are relatively large, often using larger chassis such as 4U, 6U, and 8U. The entire system can weigh hundreds of kilograms. Furthermore, the CPUs, GPUs, TPUs, and memory used in AI servers are extremely expensive. Therefore, AI servers are truly expensive and heavy items, requiring special care to prevent damage. This is especially true during transportation, where they are subject to various external mechanical forces, such as vibration, collisions, and drops. Inadequate packaging can easily damage the product, causing losses.

[0004] For these heavy, high-value rack-mounted AI servers, traditional packaging, primarily based on foam plastic cushioning, cannot meet requirements for long-term reliability, resistance to harsh weathering environments, and resistance to excessive impact from unconventional mechanical energy. Furthermore, because rack-mounted AI servers (flat structures) typically have inconsistent weight from front to back, traditional packaging cannot ensure consistent front-to-back displacement when impacted, resulting in distortion and damage. Utility Model Content

[0005] In order to solve the problem that traditional packaging based on foam plastic cushioning protection cannot meet the server packaging requirements in terms of long-term reliability, weather resistance in harsh environments, and excessive impact of unconventional mechanical energy, and traditional packaging cannot ensure that the front and rear displacement of the product is consistent when it is impacted, thereby causing front and rear twisting and damage to the product, the utility model provides a connected buffer damping structure and a server packaging structure.

[0006] On the one hand, the present invention is achieved through the following technical solutions:

[0007] A connected buffer damping structure, characterized by comprising:

[0008] two first buffer dampers arranged opposite to each other;

[0009] The first buffer damper includes a damper housing, wherein the damper housing is divided into a first damper cavity, a second damper cavity, and a third damper cavity in sequence by two damper sealing end plates; a damper piston rod is axially slidably mounted in the damper housing, and a second linkage piston and a damper piston are connected and mounted on the damper piston rod, which are respectively located in the first damper cavity and the second damper cavity; one end of the damper piston rod away from the third damper cavity extends out of the damper housing, and the other end is located in the third damper cavity;

[0010] The three-chamber damper on one of the first buffer dampers is connected to the side of the first chamber of the damper on another of the first buffer dampers away from the three-chamber damper through a connecting pipe, and the three-chamber damper on another of the first buffer dampers is connected to the side of the first chamber of the damper on one of the first buffer dampers away from the three-chamber damper through a connecting pipe.

[0011] A further improvement of the present invention is that it also includes a cylinder shell wrapped around the outside of the damper shell; the interlayer space formed by the cylinder shell and the damper shell is divided into a second cylinder cavity and a first cylinder cavity by a partition; the second cylinder cavity is connected to the side of the damper first cavity away from the three-cavity damper, and the first cylinder cavity is connected to the three-cavity damper; a second interface connected to the connecting pipe is provided on the outer wall of the second cylinder cavity; a first interface connected to the connecting pipe is provided on the outer wall of the first cylinder cavity.

[0012] A further improvement of the present invention is that the first cavity of the damper is opened on one side away from the third cavity of the damper, and a connecting hole connected to the first cylinder cavity is opened on the side of the third cavity of the damper.

[0013] A further improvement of the present invention is that the end of the damper piston rod is connected and installed with a first linkage piston located in the three-cavity body of the damper; and the communicating hole is arranged on a side away from the first cavity of the damper.

[0014] Another aspect of the present invention is achieved through the following technical solutions:

[0015] A server packaging structure, comprising a packaging box with a rectangular shell structure that can be placed outside the server and the above-mentioned interconnected buffering and damping structure;

[0016] The pair of first buffer dampers are arranged on at least one wall of the packaging box and can provide buffering support to the server.

[0017] A further improvement of the present invention is that the first buffer dampers are arranged in pairs front and back on the lower side of the server; and further comprises a plurality of second buffer dampers capable of providing buffering support to other sides of the server.

[0018] A further improvement of the present invention is that it further comprises a protective shell that can be wrapped and installed on the outside of the server, and a universal connecting seat connected to the corresponding buffer damper is connected and installed on the protective shell.

[0019] A further improvement of the present invention is that the universal connecting seat includes two oppositely arranged connecting seat ends, and a connecting frame is provided on the opposite inner sides of the two connecting seat ends; it also includes two oppositely arranged connecting rods, and the two ends of the connecting rods are respectively rotatably connected and installed with the connecting frames on the two connecting seat ends through cross pins.

[0020] A further improvement of the present invention is that the side of the protective shell close to the server is covered with a rubber lining, on which a first connector of a connecting seat connected to the universal connecting seat is installed.

[0021] A further improvement of the present invention is that a supporting rib is installed on each wall of the packaging box, and the first buffer damper and the second buffer damper are vertically installed on the supporting rib.

[0022] It can be seen from the above technical solutions that the beneficial effects of the present invention are:

[0023] The packaging box provides preliminary protection to prevent the server or buffer damper from being invaded or directly contacted by foreign objects, and serves as a basic load-bearing component; when the damper piston rod of a first buffer damper is compressed by an external impact force, the damper piston rod of the first buffer damper moves downward, thereby driving the damper piston to move, and using the damping medium in the second chamber of the damper to generate a damping force to absorb energy. At the same time, the air pressure in the lower part of the three chambers of the damper increases, and the gas is pressed into the upper part of the first chamber of the damper of another first buffer damper through a connecting pipe, and downward pressure is generated on the second linkage piston, pushing the damper piston rod of the other first buffer damper to move downward, thereby realizing the damper piston movement in the first buffer damper, and using the damping medium in the second chamber of the damper to generate a damping force to absorb energy, realizing the linkage of the two first buffer dampers, balancing the impact displacement of the two damper piston rods, and synchronizing the displacement of the front and rear ends of the product, effectively avoiding flexible torsional deformation damage to the product. This Unicom buffering and damping structure effectively reduces vibration shock, drop shock, etc. to which the product is subjected during transportation. It can provide the product with long-term, effective, and highly reliable buffering support that can adapt to harsh environments and cope with unexpected unconventional impact energy. It is very suitable for expensive rack-mounted AI server products, greatly improving the safety and reliability of transportation packaging, avoiding major economic losses, and having good economic effects.

[0035] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in the specific embodiments. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0036] like Figure 5 、 7 As shown in FIG9 , the utility model discloses a connected buffer damping structure, comprising:

[0037] Two first buffer dampers 7 arranged opposite to each other;

[0038] The first buffer damper 7 includes a damper housing 72. The damper housing 72 is divided into a first damper cavity 721, a second damper cavity 722, and a third damper cavity 723 from the top and bottom by two damper sealing end plates 77. A damper piston rod 73 is axially slidably mounted in the damper housing 72. A second linkage piston 733 and a damper piston 731 are positioned and connected to the damper piston rod 73, which are respectively located in the first damper cavity 721 and the second damper cavity 722. One end (upper end) of the damper piston rod 73 away from the third damper cavity 723 extends out of the damper housing 72 as a supporting end, and the other end (lower end) of the damper piston rod 73 is located in the third damper cavity 723.

[0039] The three-chamber 723 of the damper and the first chamber 721 of the damper on the side away from the three-chamber 723 of the damper on one of the first buffer dampers 7 are cross-connected with the three-chamber 723 of the damper and the first chamber 721 of the damper on the side away from the three-chamber 723 of the damper on the other of the first buffer dampers 7 and the second linking piston 733 through two connecting pipes 9. Figure 9 As shown; that is, the damper three-cavity 723 on the left first buffer damper 7 is connected to the upper side of the damper first cavity 721 on the right first buffer damper 7 through the connecting pipe 9, and the damper three-cavity 723 on the right first buffer damper 7 is connected to the upper side of the damper first cavity 721 on the left first buffer damper 7 through the connecting pipe 9.

[0040] When in use, the two first buffer dampers 7 of the interconnected buffer damping structure are supported at different positions on the same side of the packaged product (rack-mounted AI server) (generally at the two ends with inconsistent weights). When the damper piston rod 73 of a first buffer damper 7 is compressed by an external impact force, the damper piston rod 73 of the first buffer damper 7 moves downward, thereby driving the damper piston 731 to move, and generating a damping force to absorb energy with the help of the damping medium in the second cavity 722 of the damper. At the same time, the air pressure in the lower part of the third cavity 723 of the damper increases, and the gas is passed through a connecting pipe 9. The upper part of the first damper cavity 721 of the other first buffer damper 7 is pressed into place, and downward pressure is exerted on the second linkage piston 733, pushing the damper piston rod 73 of the other first buffer damper 7 downward, thereby realizing the movement of the damper piston 731 in the first buffer damper 7, and generating a damping force to absorb energy with the help of the damping medium in the second damper cavity 722, thereby realizing the linkage of the two first buffer dampers 7, balancing the impact displacement of the two damper piston rods 73, synchronizing the displacement of the front and rear ends of the product, and effectively avoiding flexible distortion and deformation damage to the product. This interconnected buffer damping structure effectively reduces vibration shock, drop shock, and other conditions that the product is subjected to during transportation, and can provide the product with a long-term, effective, harsh environment-adaptable, and high-reliability buffer support that can cope with unexpected unconventional impact energy. It is very suitable for expensive rack-mounted AI server products, greatly improving the safety and reliability of transportation packaging, avoiding major economic losses, and having good economic effects.

[0041] Further, such as Figure 7 As shown, the interconnected buffer damping structure also includes a cylinder housing 71 (cylindrical) wrapped around the outside of the damper housing 72 (cylindrical); an interlayer space is formed between the cylinder housing 71 and the side wall of the damper housing 72, and the interlayer space is divided into an upper second cylinder cavity 75 and a lower first cylinder cavity 76 by a partition 74; the second cylinder cavity 75 is connected to the upper side of the damper first cavity 721, that is, the high-pressure gas in the second cylinder cavity 75 can generate pressure on the upper part of the second linkage piston 733; the first cylinder cavity 76 is connected to the damper three-cavity 723; the outer wall of the second cylinder cavity 75 is provided with a second interface 751 connected to the connecting pipe 9; the outer wall of the first cylinder cavity 76 is provided with a first interface 761 connected to the connecting pipe 9. The damper's first chamber 721 is open at its top, and a communication hole 724 is provided on the side of the damper's third chamber 723, communicating with the first cylinder chamber 76. The damper's piston rod 73 is connected to the lower end thereof with a first linkage piston 732 mounted within the damper's third chamber 723; the communication hole 724 is provided on the lower edge of the sidewall of the damper's third chamber 723.

[0042] When the damper piston rod 73 of a first buffer damper 7 is compressed by the impact external force, the damper piston rod 73 of the first buffer damper 7 moves downward, thereby driving the damper piston 731 to move, and generating a damping force to absorb energy with the help of the damping medium in the second chamber 722 of the damper. At the same time, the air pressure in the lower part of the third chamber 723 of the damper increases, and the gas is pressed into the first cylinder chamber 76, and is pressed into the second cylinder chamber 75 of another first buffer damper 7 through a connecting pipe 9. The other first buffer damper 7 The high-pressure gas in the second cylinder cavity 75 generates downward pressure on the second linkage piston 733, thereby pushing the damper piston rod 73 of the other first buffer damper 7 to move downward, thereby realizing the movement of the damper piston 731 in the first buffer damper 7, and using the damping medium in the second cavity 722 of the damper to generate damping force to absorb energy, thereby realizing the linkage of the two first buffer dampers 7, balancing the impact displacement of the damper piston rod 73, and making the front and rear end displacements of the product synchronized to avoid flexible twisting deformation.

[0043] Furthermore, the second interface 751 and the first interface 761 are respectively connected to the connecting pipe 9 using quick plugs, which can achieve convenient disassembly and assembly.

[0044] like Figure 1-6 As shown, the utility model also discloses a server packaging structure, including a packaging box with a rectangular shell structure that can be covered on the outside of the server 1 and several of the above-mentioned interconnected buffer damping structures; the paired first buffer dampers 7 are arranged on at least one wall of the packaging box and can provide buffering support for the server 1.

[0045] The packaging box is used to provide preliminary protection for the packaging box to prevent the server 1 or the buffer damper from being invaded or directly contacted by foreign objects, serving as the basic load-bearing component; and the corresponding server 1 support surface is buffered and vibration-reduced through the set interconnected buffer damping structure, effectively providing the product with long-term effectiveness, adaptability to harsh environments, and ability to cope with unexpected unconventional impact energy. High-reliability packaging is very suitable for expensive rack-mounted AI server products, greatly improving the safety and reliability of transportation packaging, avoiding major economic losses, and having good economic effects.

[0046] Furthermore, as shown in 1-3, the packaging box includes a pallet 2 at the bottom and a box body 3 (with a lower opening) that is fastened to and installed on the upper side of the pallet 2. The packaging box is made of wood as a whole; it is easy to assemble and disassemble, and effectively provides preliminary protection for the server 1 packaging.

[0047] In one embodiment, Figure 1 、 5As shown, paired first buffer dampers 7 are arranged front and back on the underside of the server 1. Several second buffer dampers 6 are also included to provide cushioning support for the other sides of the server 1. These second buffer dampers 6 utilize viscous dampers or spring dampers, a conventional mechanical damper structure. The bottom surface of the server 1 is supported by this Unicom buffer damping structure, while the other surfaces utilize conventional mechanical dampers. This effectively reduces vibration and drop shock during product transportation, providing long-term, highly reliable buffering support that is adaptable to harsh environments and can withstand unexpected, unconventional impact energy.

[0048] like Figure 1 、 5 As shown in Figures 6 and 7, this server packaging structure also includes a steel plate protective housing 5 that can be mounted on the outside of the server 1. A universal connector 8, which is connected to the corresponding buffer damper, is mounted on the protective housing 5. The protective housing 5 protects the server 1 from damage, while the universal connector 8 allows the product (server 1) to move freely in a direction perpendicular to the buffer damper, preventing shear damage that would occur if the product were directly connected to the buffer damper.

[0049] like Figure 1 、 4 As shown, a supporting rib 4 is installed on the inner side of each wall of the packaging box, and the first buffer damper 7 and the second buffer damper 6 are vertically installed on the corresponding supporting rib 4, effectively ensuring the reliability of the buffer damper installation.

[0050] Furthermore, in order to improve the strength, the supporting rib 4 is made of steel plate, which is more suitable for heavy products.

[0051] Specifically, such as Figure 1 、 4 As shown, a supporting rib 4 connected end to end is provided in the middle of the four vertical sides of the packaging box, and two buffer dampers are symmetrically installed (along the length direction of the supporting rib 4) on each vertical side; two supporting ribs 4 in the front-to-back direction are respectively provided on the top and bottom surfaces of the packaging box, and the paired supporting ribs 4 are symmetrically arranged left and right, and two buffer dampers are symmetrically installed front and back on each supporting rib 4; effectively ensuring the stability of the buffering and vibration reduction of the server 1.

[0052] like Figure 8As shown, the universal connector 8 comprises two opposing connector ends 81, with connecting brackets 82 disposed on opposing inner sides of the two connector ends 81. It also comprises two opposing connecting rods 84, each end of which is rotatably connected to the connecting brackets 82 on the two connector ends 81 via a cross pin 83. The universal connector 8 has a simple structure and can withstand significant push and pull forces. The universal connector 8 provides the product with freedom of movement perpendicular to the axial direction of the buffer damper, preventing shear damage that would occur if the product were directly connected to the buffer damper.

[0053] like Figure 1 、 5 As shown in Figures 6 and 7, the protective housing 5 is a rectangular structure with two adjacent sides completely open. The inner side of each wall of the protective housing 5 is covered with a rubber lining 51, which provides a certain cushioning and protective function for the server 1. The protective housing 5 is installed at the four corners of the server 1, and each side is equipped with a first connector 52 connected to the universal connector 8. This effectively provides protective support for the server 1.

[0054] Furthermore, the protective shell 5 is opened at the vertical edge position, so that the edge structural features of the end of the server 1 can be avoided (such as the server hanging ears, etc.).

[0055] The first buffer damper 7 and the second buffer damper 6 are provided with a second connector 734 connected to the universal connector 8. The connector ends 81 at both ends of the universal connector 8 are connected to the protective housing 5 and the buffer damper through the first connector 52 and the second connector 734, respectively, to achieve convenient installation.

[0056] In another embodiment, all paired buffer dampers may adopt a connected buffer damping structure (the paired first buffer dampers 7 are cross-connected through two connecting pipes 9), thereby improving the all-round anti-twisting ability of the product.

[0057] Moreover, the packaging box, the buffer damper, the protective shell 5 and the universal connecting seat 8 all adopt a modular design, which is convenient for assembly and disassembly, and can be compatible with various rectangular products by simply adjusting the size, which is economical.

[0058] The present Unicom buffer damping structure and server packaging structure, the packaging box is protected by preliminary protection to prevent the server 1 or the buffer damper from being invaded or directly contacted by foreign objects, and serves as a basic load-bearing component; when the damper piston rod 73 of the first buffer damper 7 is compressed by the impact external force, the damper piston rod 73 of the first buffer damper 7 moves downward, thereby driving the damper piston 731 to move, and the damping medium in the second cavity 722 of the damper generates a damping force to absorb energy, and at the same time, the air pressure in the lower part of the third cavity 723 of the damper increases, and the gas is pressed into the third cavity 723 through a connecting pipe 9. The upper part of the damper first cavity 721 of the other first buffer damper 7 generates downward pressure on the second linkage piston 733, pushing the damper piston rod 73 of the other first buffer damper 7 downward, thereby realizing the movement of the damper piston 731 in the first buffer damper 7, and using the damping medium in the damper second cavity 722 to generate damping force to absorb energy, realizing the linkage of the two first buffer dampers 7, balancing the impact displacement of the two damper piston rods 73, and synchronizing the displacement of the front and rear ends of the product, effectively avoiding flexible twisting and deformation damage to the product. This interconnected buffer damping structure effectively reduces vibration shock, drop shock, etc. to which the product is subjected during transportation, and can provide the product with long-term, effective, and highly reliable buffer support that can adapt to harsh environments and cope with unexpected unconventional impact energy. It is very suitable for expensive rack-mounted AI server products, greatly improving the safety and reliability of transportation packaging, avoiding major economic losses, and having good economic effects.
