Description

Technical Field

[0001] This application relates to the field of packaging technology, and in particular to a packaging cushioning component. Background Technology

[0002] For fragile products such as large commercial display screens and turnstiles, traditional packaging cushioning materials (such as expanded polyethylene foam and honeycomb cardboard) need to be of sufficient thickness to ensure protection during logistics and transportation. However, this results in products with excessively large packaging volumes, making them inconvenient for transportation. Therefore, the demand for high-protection performance and miniaturized product packaging is gradually increasing. Summary of the Invention

[0003] Therefore, it is necessary to provide a packaging cushioning component that can achieve high protective performance with a small volume when packaging products.

[0004] The packaging cushioning assembly has an inner side and an outer side along its thickness direction, defining the inner side as the side facing the product and the outer side as the side facing outward; the packaging cushioning assembly includes a first cushioning structure and a second cushioning structure: the first cushioning structure includes a first support member and a plurality of first cushioning members, the first cushioning members being fixed to the first support member; the plurality of first cushioning members are spaced apart along a first direction; the first direction is angularly positioned with respect to the thickness direction; a first through hole is provided between two adjacent first cushioning members, the first through hole being located in the first support member; the second cushioning structure includes a plurality of second cushioning members, each second cushioning member passing through a corresponding first through hole and located inside the first support member; the second cushioning members and the first cushioning members are respectively made of a non-Newtonian fluid filling material; one of the second cushioning members and the first cushioning member is configured to protrude inward relative to the other in response to an external impact.

[0005] Understandably, the first support member provides support for the first buffer member, and the first support member has a first through hole to limit the movement of the second buffer member. Both the first and second buffer members are made of non-Newtonian fluid-filled materials, allowing them to enter a shear-thickening state to absorb impact energy upon external impact. The first and second buffer members work together to resist impacts under static load and low-speed conditions. When a medium-to-low-speed impact occurs on the packaging buffer assembly, one of the second and first buffer members protrudes inward relative to the other to locally concentrate the impact energy, increasing the local strain rate and local stress density. The inwardly protruding member quickly enters a shear-thickening state to significantly absorb impact energy, achieving buffer protection. The second and first buffer members do not need to increase their thickness to resist impacts; the packaging buffer assembly can achieve high protective performance with a relatively small volume.

[0006] In one embodiment, the second buffer structure includes a second support member; The inner side of the second support member is equipped with a plurality of second buffer members spaced apart along the first direction; the first support member is located on the inner side of the second support member and is sleeved on the second buffer member through the first through hole; the second support member is constructed with a plurality of second through holes spaced apart along the first direction, and a second through hole is provided between any two adjacent second buffer members, and the plurality of second through holes are provided in a one-to-one correspondence with the plurality of first buffer members.

[0007] In one embodiment, along the first direction, a plurality of first buffers and a plurality of second buffers are arranged alternately.

[0008] In one embodiment, along the first direction, any two adjacent first buffers and second buffers are fitted together.

[0009] In one embodiment, the plurality of first buffers and the plurality of second buffers extend straight along the thickness direction.

[0010] In one embodiment, the total surface area of ​​the plurality of first buffers and the plurality of second buffers facing the inner side is S, and the surface area of ​​a single first buffer or a single second buffer facing the inner side is a, where 0.1S≤a≤0.4S.

[0012] In one embodiment, the protective structure includes a third support member, the third support member having the protrusion; along the first direction, mounting portions are respectively provided on both sides of any one of the protrusions; The protective structure also includes a protective plate, which is disposed on the outside of the third support member along the thickness direction, and the protective plate is connected to the assembly part.

[0013] In one embodiment, the packaging cushioning assembly further includes an assembly frame surrounding the outer periphery of the first cushioning structure, the second cushioning structure, and the protective structure; the assembly frame is detachably connected to the protective structure. One of the first buffer structure and the second buffer structure is detachably connected to the assembly frame.

The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0023] Please see Figures 1 to 7This application provides a packaging cushioning component 100, which has an inner side and an outer side along its thickness direction. The inner side is defined as the side facing the product, and the outer side is the side facing outward. The packaging cushioning component 100 is disposed on the outer side of the product and can wrap the product. When the packaging cushioning component 100 is subjected to external impact, it can absorb the external impact energy to form a cushioning protection and prevent product damage.

[0024] like Figure 1 and Figure 2 As shown, in an optional embodiment, the packaging cushioning assembly 100 includes a first cushioning structure 10, which includes a first support member 11 and a plurality of first cushioning members 12. The first cushioning members 12 are fixed to the inner side of the first support member 11, and the first support member 11 supports and fixes the first cushioning members 12. The first cushioning members 12 can directly contact the product.

[0025] like Figure 2 As shown, in an optional embodiment, multiple first buffer members 12 are spaced apart along a first direction, and a first through hole 1101 is provided between any two adjacent first buffer members 12. The first through hole 1101 is located in the first support member 11. The packaging buffer assembly 100 also includes a second buffer structure 20, which includes multiple second buffer members 22. Each second buffer member 22 passes through a corresponding first through hole 1101 and is located inside the first support member 11. The first support member 11, by providing the first through hole 1101, facilitates the rapid assembly of the second buffer member 22, and the hole wall of the first through hole 1101 can limit the second buffer member 22. In this way, the first buffer member 12 and the second buffer member 22 can jointly resist external impacts and provide buffer protection.

[0026] In related technologies, the impacts encountered during packaging and transportation include static impact, low-speed impact, and medium-to-low-speed impact. Traditional packaging cushioning materials typically use materials such as expanded polyethylene foam and honeycomb cardboard. These traditional cushioning materials, when used with traditional packaging methods, can generally only withstand static and low-speed impacts. To further withstand medium-to-low-speed impacts and meet the high protection requirements of products under such conditions, the only solution is to increase the thickness of the cushioning material. However, this inevitably leads to excessively large packaging volumes, affecting transportation.

[0027] In an optional embodiment, the second buffer 22 and the first buffer 12 are respectively made of a non-Newtonian fluid filling material. Under high-speed impact conditions, the mechanical properties of this material can respond reversibly to changes in shear stress in a timely manner, that is, the material can change from soft to hard, thereby achieving rapid and efficient impact resistance of flexible materials.

[0028] While this material exhibits excellent hardening energy absorption properties under high-speed impact, its high response threshold makes it difficult to effectively trigger hardening under low-to-medium speed impacts in product transportation scenarios, leading to buffer failure. Related technologies primarily reduce the response threshold through material modification, such as adding nanoparticles or adjusting the polymer matrix, but this is costly and may sacrifice material durability. This application achieves a structural fit between the first buffer 12 and the second buffer 22 to provide good buffering performance under low-to-medium speed impacts.

[0029] In this application, the packaging cushioning assembly 100 has a first state and a second state. In the first state, the first cushioning member 12 and the second cushioning member 22 are flush and arranged along a first direction, forming a large area to jointly resist impacts under static load and low speed conditions. In the second state, one of the second cushioning member 22 and the first cushioning member 12 is configured to protrude inward relative to the other in response to an external impact. Here, the external impact refers to a low-speed external impact. Thus, when the packaging cushioning assembly 100 experiences a low-to-medium speed impact, the impact force can cause one of the second cushioning member 22 and the first cushioning member 12 to bulge inwards. At this point, the original arrangement of the second cushioning member 22 and the first cushioning member 12 is disrupted, and the impact force cannot be dispersed in all directions. The impact energy is concentrated on the inwardly bulging member, increasing the local strain rate and local stress density. This causes the inwardly bulging member to more easily enter a shear thickening state under the concentrated impact energy, hardening from soft to hard, thereby significantly increasing the impact energy absorption. In this way, without altering the material properties, material hardening can be effectively triggered under low-to-medium speed impacts, reducing production costs and maintaining material durability.

[0030] In summary, the second buffer 22 and the first buffer 12 are both made of non-Newtonian fluid filling materials. The second buffer 22 and the first buffer 12 together form a large area to jointly resist impacts under static load and low-speed conditions. When a medium-to-low-speed impact occurs on the packaging buffer assembly 100, one of the second buffer 22 and the first buffer 12 protrudes inward relative to the other, so that the impact energy is focused, making it easier to enter a shear thickening state and improving the efficiency of impact energy absorption. At this time, there is no need to increase the thickness of the material to improve the cushioning effect, thus improving the protective performance while promoting the miniaturization of the packaging buffer assembly 100.

[0031] In this diagram, the first direction and the thickness direction are set at an angle. For ease of explanation, a second direction is introduced, and the first direction, the second direction, and the thickness direction are set perpendicular to each other. Here, a rectangular coordinate system is introduced, with the first direction as the x-axis, the second direction as the y-axis, and the thickness direction as the z-axis for illustration.

[0032] like Figure 1 and 2 As shown, in a specific embodiment, the second buffer structure 20 includes a second support member 21. A plurality of second buffer members 22, spaced apart along a first direction, are installed on the inner side of the second support member 21, and the second support member 21 supports the plurality of second buffer members 22. A first support member 11 is disposed on the inner side of the second support member 21, and the first support member 11 is sleeved onto the second buffer member 22 through a first through hole 1101. The first buffer structure 10 and the second buffer structure 20 mutually limit each other.

[0033] like Figure 2 As shown, in a specific embodiment, the second support member 21 is constructed with a plurality of second through holes 2101 spaced apart along the first direction. A second through hole 2101 is provided between any two adjacent second buffer members 22. The plurality of second through holes 2101 are provided in a one-to-one correspondence with the plurality of first buffer members 12, so that external force can be directly transmitted to the first buffer member 12 through the first through hole 1101.

[0034] For ease of explanation, this application will be described using the example of a second state in which the first buffer 12 is configured to bulge inward relative to the second buffer 22 in response to an external impact. Specifically, the first buffer 12 can be pushed inward under a low-to-medium speed impact, forming a state in which it bulges inward relative to the second buffer 22.

[0035] In a specific embodiment, the non-Newtonian fluid filling material can be set as a non-Newtonian fluid polyester to avoid the risk of leakage caused by directly filling non-Newtonian fluids.

[0036] like Figure 1 As shown, in a specific embodiment, along the first direction, multiple first buffers 12 and multiple second buffers 22 are arranged in an alternating manner so that the first buffers 12 and the second buffers 22 are evenly distributed. The first buffers 12 and the second buffers 22 can work together to fully resist static loads and low-speed impacts. Moreover, when the packaging buffer assembly 100 is subjected to a medium- or low-speed impact at any position, a corresponding first buffer 12 can be pushed out and enter a shear thickening state, thereby absorbing a large amount of impact energy.

[0037] like Figure 1 As shown, in a specific embodiment, along the first direction, any two adjacent first buffer members 12 and second buffer members 22 are in contact with each other, which helps to form a continuous surface. Under static load and low-speed impact, the external force can be quickly dispersed, so that the buffering is gentler and the energy consumption is more uniform, thereby forming a better buffering effect.

[0038] like Figure 1 and Figure 2As shown, in a specific embodiment, multiple first buffers 12 and multiple second buffers 22 extend straight along the thickness direction so that the first buffers 12 can be quickly ejected when subjected to low-to-medium speed impacts. At the same time, the manufacturing process is also simpler, which helps to improve production efficiency.

[0039] In other embodiments, a plurality of first buffer members 12 and a plurality of second buffer members 22 extend bent along the thickness direction, and the corresponding first through holes 1101 are adapted to the shape of the second buffer members 22. Thus, adjacent first buffer members 12 and second buffer members 22 can have a larger area when they are fitted together, promoting a tighter fit and improving the buffering effect under static load and low-speed impact in the first state. For example, the plurality of first buffer members 12 and the plurality of second buffer members 22 extend in a wavy shape along the thickness direction.

[0040] In a specific embodiment, both the first buffer 12 and the second buffer 22 are configured as a cuboid structure. In other embodiments, they can also be configured as a prism or an irregular shape, etc., without specific limitations.

[0041] In a specific embodiment, the total surface area of ​​the plurality of first buffer members 12 and the plurality of second buffer members 22 facing inward is S, and the surface area of ​​a single first buffer member 12 facing inward is a, where 0.1S ≤ a ≤ 0.4S. Thus, by limiting the range of the ratio of a single first buffer member 12 to the total surface area, while ensuring its own structural strength, the first buffer member 12 can immediately and rapidly focus impact energy under low-to-medium speed impacts, thereby quickly being triggered to enter a shear thickening state. For example, a = 0.1S, 0.2S, or 0.4S.

[0042] In another embodiment, in the second state, the second buffer 22 is configured to protrude inward relative to the first buffer 12 in response to an external impact. In this case, the surface area of ​​the inner side of a single second buffer 22 is also defined as a. The specific range and effect can be referred to the above embodiment, and will not be repeated here.

[0043] like Figures 3 to 5As shown, in a specific embodiment, the packaging cushioning assembly 100 further includes a protective structure 30, which is installed on the outside of the second cushioning structure 20. The protective structure 30 has a plurality of protrusions 301 spaced apart along a first direction and protruding inward. The first cushioning member 12 is correspondingly disposed with the protrusions 301. For example, the protrusions 301 are in contact with the first cushioning member 12; or, a small gap is formed between the protrusions 301 and the first cushioning member 12. In this way, the protrusions 301 can transmit external force to the first cushioning member 12, causing the first cushioning member 12 to push inward. Specifically, the protrusions 301 can contact the first cushioning member 12 through the second through hole 2101 to achieve rapid force transmission. Under the force of the protrusions 301, the first cushioning member 12 can push inward relative to the second cushioning member 22, which can reduce or avoid the impact energy being dispersed by the surrounding second cushioning member 22, thereby focusing the impact energy on the first cushioning member 12, so that the first cushioning member 12 can smoothly enter the shear thickening state.

[0044] In another embodiment, in the second state, the second buffer 22 is configured to protrude inward relative to the first buffer 12 in response to an external impact. In this case, the second buffer 22 is correspondingly arranged with the protrusion 301. For details, please refer to the above embodiment, which will not be repeated here.

[0045] In a specific embodiment, the protective structure 30 includes a third support member 31, which has a protrusion 301.

[0046] like Figure 3 and Figure 4 As shown, in a more specific embodiment, the third support member 31 bends itself to form a protrusion 301, which facilitates the rapid transmission of force, reduces installation steps, and improves production efficiency.

[0047] like Figure 3 and Figure 4 As shown, in some embodiments, along the first direction, mounting portions 311 are respectively provided on both sides of any protrusion 301. The protective structure 30 also includes a protective plate 32, which is disposed on the outside of the third support member 31 along the thickness direction. The protective plate 32 is connected to the mounting portion 311, and the protective plate 32 can disperse the stress of external impact. When subjected to a medium-to-low speed external impact, this impact energy is relatively large, and the protective plate 32 cannot completely disperse the impact force. Most of the concentrated impact energy is transmitted to the protrusion 301, and further transmitted to the first buffer member 12 through the protrusion 301, so that the first buffer member 12 enters a shear thickening state.

[0048] like Figures 5 to 7As shown, in some embodiments, the packaging cushioning assembly 100 further includes an assembly frame 40, which surrounds the outer periphery of the first cushioning structure 10, the second cushioning structure 20, and the protective structure 30 to limit their movement. The assembly frame 40 is detachably connected to the protective structure 30, and one of the first cushioning structure 10 and the second cushioning structure 20 is detachably connected to the assembly frame 40. Thus, the assembly frame 40 can support the protective structure 30, the first cushioning structure 10, and the second cushioning structure 20, and the detachable connection facilitates easy disassembly and replacement.

[0049] like Figure 2 , Figure 5 and Figure 6 As shown, in a specific embodiment, one of the assembly frame 40 and the second support member 21 is provided with a first mounting hole 401, and the other is provided with a first tongue 211. The first tongue 211 is inserted into the first mounting hole 401 to form mutual limiting. The assembly frame 40 can limit the second buffer structure 20 so that the first buffer structure 10 can be pushed out towards the inward side more easily.

[0050] like Figure 5 and Figure 7 As shown, in a specific embodiment, the assembly frame 40 is provided with first mounting holes 401 on both sides along the first direction, and two first mounting holes 401 are provided on each side. The two first mounting holes 401 are spaced apart along the second direction. Each first mounting hole 401 is assembled with a corresponding second tongue 302. This arrangement enables the assembly frame 40 to evenly support the second support member 21.

[0051] In some embodiments, the first support member 11 is configured as a first support plate to form a flat surface for mounting the first buffer structure 10.

[0052] like Figure 2 As shown, in a more specific embodiment, the second support member 21 is configured as a second support plate. The second support plate facilitates the formation of a flat surface to fit against the first support plate, thereby distributing the force and enabling better installation of the second buffer structure 20. The two sides of the second support plate are bent to form connecting portions 212, which are configured with the aforementioned first tongue 211. The assembly frame 40 is correspondingly configured with a first mounting hole 401.

[0053] like Figures 3 to 7As shown, in a specific embodiment, one of the assembly frame 40 and the protective structure 30 is provided with a second mounting hole 402, and the other is provided with a second tongue 302. The second tongue 302 is inserted into the second mounting hole 402 to form mutual restraint, so that the position of the protective structure 30 is relatively stable, which is conducive to the effective transmission of external forces. For example, the protective plate 32 is provided with a second tongue 302, and the assembly frame 40 is provided with a second mounting hole 402.

[0054] like Figure 5 and Figure 7 As shown, in a specific embodiment, along the first direction, a second mounting hole 402 is provided on each side of the assembly frame 40. The second mounting hole 402 on each side is located between two first mounting holes 401, and each second mounting hole 402 is assembled with a corresponding second tongue 302. This arrangement allows the assembly frame 40 to uniformly support the protective structure 30.

[0055] like Figure 5 Right now Figure 7 As shown, in a specific embodiment, the second mounting hole 402 includes a first segment 4021 and a second segment 4022. The first segment 4021 is connected to the second segment 4022. Along the thickness direction, the space of the second segment 4022 gradually narrows outward from the first segment 4021 to form a slope, which plays a guiding role in the disassembly and assembly of the second tongue 302 and a limiting role after the second tongue 302 is assembled.

[0056] In a specific embodiment, the first support member 11, the second support member 21, and the protective structure 30 are all made of cardboard, which is easy to bend and can deform to a certain extent, making assembly easier, production costs lower, and easier to put into mass production.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
