Description

Technical Field

[0001] This utility model relates to the field of server packaging technology, and more specifically, to an inner packaging cushioning component for servers. Background Technology

[0002] Heavy-duty servers are high-value, precision equipment that are sensitive to impact and vibration during transportation. Therefore, they require specially designed internal cushioning packaging to protect them from impact and vibration. The most common material for this cushioning is EPE.

[0003] Heavy-duty servers use conventional EPE (Extra Polyethylene) inner packaging padding. Due to the material's characteristics, the packaging method is essentially fixed. To protect the six outer surfaces of the server, current technology often uses a large amount of EPE to connect and form a wrap-around structure. In particular, to reinforce the server's center of gravity and vulnerable points, corresponding EPE structures are used for cushioning. However, to avoid the EPE padding structure becoming too scattered and to maintain its position and prevent displacement, these structures are usually connected as a whole. This results in a larger amount of EPE used, leading to higher costs. In addition, because the EPE structure is fixed, the volume occupied before and after use is the same. This results in a larger volume of packaging material before use, leading to higher warehousing and logistics costs. Utility Model Content

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0035] To address the issue of high packaging costs for servers in existing technologies, this invention provides an inner packaging cushioning component for servers.

[0036] like Figures 1 to 11 As shown, the inner packaging cushioning assembly for the server includes a first air column structure 10, a second air column structure 20, and a third air column structure 30. The first air column structure 10 has a receiving groove 11 and a first slot, a second slot, and a third slot communicating with the receiving groove 11. The first air column structure 10 provides cushioning support for the first, second, and third outer surfaces of the server 3 connected sequentially. The second air column structure 20 covers the first slot to provide cushioning support for the fourth outer surface of the server 3. A portion of the third air column structure 30 covers the second slot, and another portion covers the third slot to provide cushioning support for the fifth and sixth outer surfaces of the server 3, respectively. The first air column structure 10, the second air column structure 20, and the third air column structure 30 form a receiving cavity for accommodating the server 3.

[0037] The inner packaging cushioning assembly provided in this application uses air as filling, which not only supports the server 3 but also provides cushioning. The first air column structure 10, the second air column structure 20, and the third air column structure 30 in the inner packaging cushioning assembly provided in this application are all air column structures. When not in use, they are all in a thin film state, ensuring that the inner packaging cushioning assembly does not occupy a large storage space. When needed, the first air column structure 10, the second air column structure 20, and the third air column structure 30 can be inflated respectively. Since the first air column structure 10, the second air column structure 20, and the third air column structure 30 are all hollow air columns, it is beneficial to save materials and ensure that the inner packaging cushioning assembly uses low material and storage costs.

[0038] It should be noted that, in this application, the shape of the cavity is adapted to the external shape of the server 3. This ensures the reliable support of the inner packaging cushioning assembly for the first, second, third, fourth, fifth, and sixth outer surfaces of the server 3.

[0039] like Figures 1 to 3 The diagram shows the structure of the inner packaging buffer assembly inside the outer packaging box 2 after it wraps around the server 3.

[0040] like Figure 4 and Figure 5 As shown, the first air column structure 10 is U-shaped. In this way, by setting the first air column structure 10 into a U-shaped structure, a single complete first air column structure 10 can provide cushioning support for the continuous first outer surface, second outer surface, and third outer surface of the server 3, which helps to reduce the processing and manufacturing difficulty of the inner packaging cushioning components.

[0041] like Figure 4 and Figure 5 As shown, the first air column structure 10 includes two first sub-air column units 12, each L-shaped. The two L-shaped first sub-air column units 12 are connected to form a U-shaped first air column structure 10. Each first sub-air column unit 12 includes a first supporting air column 121 and a second supporting air column 122. The first supporting air column 121 extends horizontally. The second supporting air column 122 is connected to the first end of the first supporting air column 121 to form an L-shaped first sub-air column unit 12. The second end of the first supporting air column 121 of the first sub-air column unit 12 is connected to the second end of the first supporting air column 121 of the second sub-air column unit 12 to form a U-shaped first air column structure 10. In this way, by connecting the middle edges of the two independent first sub-air column units 12 with a heat-pressed wire to form a concave structure, the first air column structure 10 ensures that it provides buffer support for the first, second, and third outer surfaces of the server 3.

[0042] like Figure 6As shown, the first supporting air column 121 includes two layers of first flat air columns 1211, which are stacked and arranged parallel to the second outer surface; the second supporting air column 122 has a four-level layered structure; the first layer of the second supporting air column 122 includes a second flat air column 1221, which is connected to the first flat air column 1211 located on the upper layer, and the second flat air column 1221 in the first first sub-air column unit 12 is also connected to the first flat air column 1211 located on the upper layer. 221 is parallel to the first outer surface, and the second flat air column 1221 in the second first sub-air column unit 12 is parallel to the third outer surface; the second layer of the second supporting air column 122 includes at least two first bent air columns 1222, which support and cooperate with the second flat air column 1221; the third layer of the second supporting air column 122 includes a plurality of first vertical air columns 1223, at least two of which are used to connect with a first bent air column 1222, and at least two of the remaining first vertical air columns 1223 support and cooperate with the second flat air column 1221; wherein, each first vertical air column 1223 in the first first sub-air column unit 12 is perpendicular to the first outer surface, and each first vertical air column 1223 in the second first sub-air column unit 12 is perpendicular to the third outer surface; the fourth layer of the second supporting air column 122 includes a plurality of second bent air columns 1221. The air column 1224, at least two of the second bent air columns 1224 located between the bottom and top are connected to the corresponding first vertical air column 1223. The bottom second bent air column 1224 is connected to the lower first flat air column 1211, and the top second bent air column 1224 is connected to the upper first flat air column 1211. In this way, the two layers of first flat air columns 1211 of the first supporting air column 121 provide good and stable support for the second outer surface of the server 3. Furthermore, by setting the second supporting air column 122 in a four-level layered structure, the reliability of the first second supporting air column 122's support for the first outer surface of the server 3 and the reliability of the second second supporting air column 122's support for the third outer surface of the server 3 are ensured.

[0043] It should be noted that in this application, the first end of the first flat air column 1211 located in the lower layer is bent in a serpentine manner to form a first vertical air column 1223, a first bent air column 1222, a first vertical air column 1223, a second bent air column 1224, and a first vertical air column 1223. At the same time, the first end of the first flat air column 1211 located in the upper layer is bent in a serpentine manner to form a first vertical air column 1223, a second bent air column 1224, a first vertical air column 1223, a first bent air column 1222, a first vertical air column 1223, a second bent air column 1224, and a first vertical air column 1223. Finally, the first vertical air column 1223 at the end of the first end of the first flat air column 1211 located in the lower layer is connected to the first vertical air column 1223 at the end of the first end of the first flat air column 1211 located in the upper layer through a hot-pressing wire connection.

[0044] like Figure 6 As shown, frame A represents the first layer of the second support air column 122, frame B represents the second layer of the second support air column 122, frame C represents the third layer of the second support air column 122, and frame D represents the fourth layer of the second support air column 122.

[0045] like Figure 7 and Figure 8 As shown, the second air column structure 20 is a four-level layered structure. The first layer of the second air column structure 20 includes a third horizontal air column 21 and two second vertical air columns 22. The two second vertical air columns 22 are connected to both ends of the third horizontal air column 21. The third horizontal air column 21 is parallel to the fourth outer surface, and each second vertical air column 22 is perpendicular to the fourth outer surface. The second layer of the second air column structure 20 includes at least two third bent air columns 23, which support and cooperate with the third horizontal air column 21. The third layer of the second air column structure 20 includes... Multiple third vertical air columns 24, at least two of which are connected to a third bent air column 23, are perpendicular to the fourth outer surface. The fourth layer of the second air column structure 20 includes multiple fourth bent air columns 25 and two fourth flat air columns 26. The upper fourth flat air column 26 is connected to the upper second vertical air column 22, and the lower fourth flat air column 26 is connected to the lower second vertical air column 22. Thus, by setting the second air column structure 20 into a four-level layered structure, the second air column structure 20 effectively buffers and supports the fourth outer surface of the server 3.

[0046] like Figure 8 As shown, frame E represents the first layer of the second air column structure 20, frame F represents the second layer of the second air column structure 20, frame G represents the third layer of the second air column structure 20, and frame H represents...

[0047] like Figures 9 to 11 As shown, the third air column structure 30 is L-shaped. By setting the third air column structure 30 to an L-shape, it ensures that the L-shaped third air column structure 30 effectively supports and buffers the fifth and sixth outer surfaces of the server 3. This is the fourth layer of the second air column structure 20.

[0048] Furthermore, such as Figures 9 to 11 As shown, the third air column structure 30 includes a second sub-air column unit 31 and a third sub-air column unit 32 connected to each other. The height of the second sub-air column unit 31 is the same as the height of the second air column structure 20. The second sub-air column unit 31 is disposed opposite to the second air column structure 20 and is parallel to the sixth outer surface. The third sub-air column unit 32 is parallel to the fifth outer surface. At least the upper surface of the third sub-air column unit 32 facing away from the receiving cavity has a limiting groove 321, which is used to place the accessory box 1 of the server 3. In this way, by connecting the second sub-air column unit 31 and the third sub-air column unit 32 with a hot-pressed wire to form an L-shaped third air column structure 30, the manufacturing convenience of the third air column structure 30 is ensured, while also ensuring the effective support of the second sub-air column unit 31 for the sixth outer surface of the server 3 and the effective support of the third sub-air column unit 32 for the fifth outer surface of the server 3.

[0049] like Figure 1 As shown, there are multiple limiting grooves 321, and at least two of the limiting grooves 321 have different sizes to accommodate different accessory boxes 1 of the server 3. In this way, the inner packaging cushioning component provided by this application can achieve a relatively orderly arrangement of the different accessory boxes 1 of the server 3, and ensure that the accessory boxes 1 will still be limited within the limiting grooves 321 when the server 3 is subjected to impact during transportation.

[0050] Furthermore, such as Figures 9 to 11As shown, the third sub-air column unit 32 includes a third supporting air column 322, a fourth supporting air column 323, and a fifth supporting air column 324. The third supporting air column 322 extends horizontally. The fourth supporting air column 323 is connected to the third supporting air column 322 and has a first limiting groove 321. The fifth supporting air column 324 is connected to the third supporting air column 322 and is located behind the fourth supporting air column 323. The fifth supporting air column 324 is L-shaped, and its width is smaller than that of the third supporting air column 322, so that the fifth supporting air column 324 and the third supporting air column 322 form a second limiting groove 321. The depth of the second limiting groove 321 is greater than the depth of the first limiting groove 321. In this way, by setting the third sub-air column unit 32 into a structure including the third support air column 322, the fourth support air column 323 and the fifth support air column 324, it is ensured that the third sub-air column unit 32 can effectively support the fifth outer surface of the server 3.

[0051] It should be noted that in this application, the second sub-gas column unit 31 is a four-level layered structure with the same structure as the second gas column structure 20. The specific structure of the second sub-gas column unit 31 will not be described in detail here.

[0052] The present invention provides an inner packaging cushioning component for a server, comprising a first air column structure 10, a second air column structure 20, and a third air column structure 30. The first air column structure 10 has a receiving groove 11 and a first slot, a second slot, and a third slot communicating with the receiving groove 11. The first air column structure 10 provides cushioning support for the sequentially connected first, second, and third outer surfaces of the server. The second air column structure 20 covers the first slot to provide cushioning support for the fourth outer surface of the server. A portion of the third air column structure 30 covers the second slot, and another portion covers the third slot, respectively providing cushioning support for the fifth and sixth outer surfaces of the server. The first air column structure 10, the second air column structure 20, and the third air column structure 30 form a receiving cavity for accommodating the server.

[0053] The inner packaging cushioning assembly provided in this application uses air as filling, which not only supports the server but also provides cushioning. The first air column structure 10, the second air column structure 20, and the third air column structure 30 in the inner packaging cushioning assembly provided in this application are all air column structures. When not in use, they are all in a thin film state, ensuring that the inner packaging cushioning assembly does not occupy a large storage space. When needed, the first air column structure 10, the second air column structure 20, and the third air column structure 30 can be inflated respectively. Since the first air column structure 10, the second air column structure 20, and the third air column structure 30 are all hollow air columns, it is beneficial to save materials and ensure that the inner packaging cushioning assembly uses low material and storage costs.
