[0017] This utility model proposes a packaging cushioning structure 100.
[0018] Please see Figure 1 and Figure 2In one embodiment of the present invention, the packaging buffer structure 100 has a buffer plane 1, and a buffer member 2 is protruding from the buffer plane 1.
[0019] In this embodiment, the packaging cushioning structure 100 achieves a better cushioning effect by protruding cushioning elements 2 on the cushioning plane 1. Specifically, the cushioning element 2 is a cushioning rib structure protruding on the cushioning plane 1. The cushioning element 2 can be a cylinder, frustum, cuboid, or other irregular protrusion on the cushioning plane 1. This protrusion design can disperse the impact force on the cushioning plane 1 to multiple parts of the cushioning plane 1, thereby effectively absorbing and weakening the impact force generated by the top falling. The packaging cushioning structure 100 of this utility model significantly improves the cushioning performance by protruding cushioning elements 2 on the cushioning plane 1, solving the problem that the existing cushioning plane 1 design is too simple and the cushioning effect is insufficient. Compared with the traditional packaging cushioning structure 100, this solution can not only effectively reduce the risk of product damage due to impact and vibration during transportation and storage, but also reduce packaging costs by optimizing material use and simplifying production processes. The assembly of this structure is simple, further improving production efficiency. By replacing conventional materials (such as EPE) with expandable polystyrene (EPS), this utility model also achieves material cost reduction, with significant economic benefits and broad application prospects.
[0020] In one embodiment of this utility model, please refer to Figure 2 The buffer 2 has a reinforcing section 21 close to the buffer plane 1 and a buffer section 22 away from the buffer plane 1. When the packaging buffer structure 100 is impacted, the buffer section 22 can deform to protect the product to be protected. The reinforcing section 21 connects the buffer section 22 and the buffer plane 1.
[0021] In one embodiment, the buffer component 2 is divided into a reinforcing section 21 near the buffer plane 1 and a buffer section 22 away from the buffer plane 1. The reinforcing section 21 is firmly connected to the buffer plane 1 by bonding or integral molding, providing support and fixation to ensure that the buffer component 2 will not easily shift or be damaged when subjected to impact. The buffer section 22 is made of flexible material or has an elastic structure design, which can deform when subjected to impact, thereby absorbing and dispersing the impact force; this material can be expandable polystyrene or expanded polystyrene foam. This segmented design allows the buffer component 2 to provide stable support while effectively buffering external impacts, ensuring the safety of the product during transportation or use. Through the segmented design of the reinforcing section 21 and the buffer section 22, an organic combination of buffering performance and structural stability is achieved. The deformation capability of the buffer section 22 can effectively absorb impact force, reducing the risk of product damage due to collision during transportation or use. The reinforcement section 21 ensures a firm connection between the buffer component 2 and the buffer plane 1, preventing the buffer component 2 from shifting or falling off during impact, thereby improving the reliability of the entire packaging buffer structure 100.
[0022] In one embodiment of this utility model, please refer to Figure 2 The cross-sectional area of the buffer section 22 gradually decreases from the end of the buffer member 2 near the buffer plane 1 to the direction away from the buffer plane 1.
[0023] In this embodiment, the cross-sectional area of the buffer segment 22 gradually decreases from one end near the buffer plane 1 towards the other. This structure can be achieved by selecting suitable materials (such as elastic polymers or foam materials) and using processes such as injection molding and foaming. During the molding process, the cross-sectional area of the buffer segment 22 is controlled by the mold design to form a wedge-shaped or conical structure. When the buffer component 2 is impacted, the gradually decreasing cross-sectional area of the buffer segment 22 can more effectively disperse the impact force. At the same time, its shape design allows the buffer segment 22 to deform uniformly under stress, thereby achieving a more efficient energy absorption and buffering effect. This structure allows the buffer segment 22 to more evenly disperse the impact force when impacted, avoiding stress concentration, thereby effectively reducing the risk of product damage due to collision during transportation or use. Simultaneously, the gradually decreasing cross-sectional area design also improves the deformation capacity of the buffer segment 22, further enhancing the buffering effect. This unique structural design not only optimizes the performance of the buffer component 2 but also improves the reliability and safety of the entire packaging buffer structure 100, demonstrating significant practicality and innovation.
[0024] In one embodiment of this utility model, please refer to Figure 2 The buffer section 22 has a buffer end face 221 at the end facing away from the buffer plane 1, and the buffer end face 221 is arranged parallel to the buffer plane 1.
[0025] In one embodiment, the distal end of the buffer section 22 is provided with a buffer end face 221 parallel to the buffer plane 1. This design can be achieved through injection molding, foam molding, or other suitable manufacturing processes. During manufacturing, the shape and size of the mold are precisely controlled to ensure that the buffer end face 221 remains parallel to the buffer plane 1. When the buffer member 2 is impacted, the buffer end face 221 can contact the product to be protected and evenly disperse the impact force through its parallel structure, thereby achieving a highly efficient buffering effect. In addition, the design of the buffer end face 221 can be further enhanced by surface treatment or the addition of wear-resistant and anti-slip coatings as needed. The parallel buffer end face 221 ensures that the impact force is evenly distributed at the moment of contact, avoiding product damage caused by local stress concentration. This design also improves the contact stability between the buffer member 2 and the product to be protected, reducing displacement or shaking caused by impact.
[0026] In one embodiment of this utility model, please refer to Figure 2The end of the buffer member 2 away from the buffer plane 1 also has a buffer transition section 23, which connects the buffer section 22 and the buffer plane 1.
[0027] In this embodiment, a buffer transition section 23 is designed at the end of the buffer member 2 furthest from the buffer plane 1, connecting the buffer section 22 and the buffer plane 1. The buffer transition section 23, through a progressive structural design, achieves a smooth transition from the buffer section 22 to the buffer plane 1. During manufacturing, the buffer transition section 23 can be integrally formed with the buffer section 22 and the buffer plane 1 through processes such as injection molding, foam molding, or machining, ensuring the integrity and stability of the structure. The shape of the buffer transition section 23 can be designed as an arc, a slope, or other progressive structure according to actual needs to optimize buffering performance and stress distribution. By setting the buffer transition section 23, buffering performance and structural stability can be significantly improved. The design of the buffer transition section 23 can effectively disperse impact force, preventing damage due to stress concentration at the connection between the buffer section 22 and the buffer plane 1, thereby extending the service life of the buffer member 2. Simultaneously, this progressive structural design can also optimize the overall stress distribution of the buffer member 2, further improving the buffering effect and ensuring the safety of the product during transportation and storage. The addition of the buffer transition section 23 not only enhances the reliability of the buffer component 2, but also improves the performance of the entire packaging buffer structure 100, demonstrating significant practicality and innovation.
[0028] In one embodiment of this utility model, please refer to Figure 2 The buffer plane 1 is provided with at least two buffer members 2, and each buffer member 2 is spaced apart.
[0029] In this embodiment, at least two buffer elements 2 are protruding from the buffer plane 1, and each buffer element 2 is spaced apart. This design can be achieved through injection molding, foam molding, or other suitable manufacturing processes. During manufacturing, the buffer elements 2 are evenly distributed on the buffer plane 1 through mold design and molding process, ensuring that a certain distance is maintained between each buffer element 2. The shape and size of the buffer elements 2 can be adjusted according to the specific needs of the product, for example, designed as a strip, circle, or rectangle, to meet different buffering requirements. In addition, the spacing of the buffer elements 2 can be achieved by adjusting the gap of the mold, ensuring that there is enough space between the buffer elements 2 so that they can deform independently when subjected to impact. By providing at least two spaced buffer elements 2 on the buffer plane 1, the packaging buffer structure 100 can significantly improve the buffering performance and the protective effect of the product. The spaced buffer elements 2 can independently absorb and disperse the impact force, avoid stress concentration, and thus more effectively protect the product from the effects of impact and vibration.
[0030] In one embodiment of this utility model, please refer to Figure 2A buffer fillet 24 is provided between two adjacent buffer components 2. The buffer fillet 24 is used to buffer the force on the two adjacent buffer components 2.
[0031] In one embodiment, a rounded corner 24 is provided between two adjacent buffer components 2. This design can be achieved through injection molding, foam molding, or other suitable manufacturing processes. During manufacturing, a rounded corner structure is pre-reserved between adjacent buffer components 2 through mold design, so that the rounded corner 24 is integrally formed with the buffer component 2. The radius of the rounded corner 24 can be adjusted according to actual needs to ensure effective stress dispersion when subjected to impact. In addition, the design of the rounded corner 24 can also be optimized in combination with the shape and size of the buffer component 2 to further improve the cushioning performance. For example, for a long strip-shaped buffer component 2, the rounded corner 24 can be designed as a semi-circle or ellipse to better adapt to the distribution of impact force. By providing a rounded corner 24 between adjacent buffer components 2, the packaging cushioning structure 100 can significantly improve the cushioning performance and structural reliability. The design of the rounded corner 24 can effectively disperse the impact force received by adjacent buffer components 2, avoid structural damage caused by stress concentration, and thus extend the service life of the buffer component 2.
[0032] In one embodiment of this utility model, please refer to Figure 2 The buffer plane 1 is provided with multiple sets of buffer components 2, and each set of buffer components 2 is spaced apart.
[0033] In this embodiment, multiple sets of buffer elements 2 are protruding from the buffer plane 1, with each set of buffer elements 2 spaced apart. This structure can be achieved through injection molding, foam molding, or other suitable manufacturing processes. During the design process, the buffer elements 2 are distributed on the buffer plane 1 according to a predetermined number of sets and spacing. Each set of buffer elements 2 may contain one or more buffer units, and the specific number and shape are adjusted according to the product size and buffering requirements. By rationally designing the layout and spacing of the buffer elements 2, sufficient space is ensured between each set of buffer elements 2 to independently absorb and disperse impact forces, thereby achieving a more efficient buffering effect. In addition, the shape (such as a strip, circle, or rectangle) and size of the buffer elements 2 can also be optimized according to actual needs to meet the packaging requirements of different products.
[0034] In one embodiment of this utility model, please refer to Figure 2 The buffer 2 also has a connecting section 25 near the buffer plane 1. The connecting section 25 connects the buffer plane 1 and the reinforcing section 21. The cross-sectional area of the connecting section 25 gradually decreases from the end of the buffer 2 near the buffer plane 1 to the direction away from the buffer plane 1.
[0035] In one embodiment, the buffer member 2 has a connecting segment 25 at one end near the buffer plane 1, which connects the buffer plane 1 and the reinforcing segment 21. The cross-sectional area of the connecting segment 25 gradually decreases from the end near the buffer plane 1 to the direction away from the buffer plane 1, forming a wedge-shaped or conical structure. This structure can be achieved by injection molding, foam molding, or other suitable manufacturing processes. During manufacturing, the shape and size of the connecting segment 25 are precisely controlled through mold design, so that it has a larger cross-sectional area at the end near the buffer plane 1 to ensure a firm connection with the buffer plane 1; while in the direction away from the buffer plane 1, the cross-sectional area gradually decreases to achieve more flexible buffering performance. The connecting segment 25 can be designed as a rounded corner structure or a beveled corner structure; the material of the connecting segment 25 can be a polymer material with elasticity and toughness to ensure that it can effectively disperse stress when subjected to impact, while maintaining the stability of the structure.
[0036] This utility model also proposes a packaging set 200, please refer to [link / reference]. Figure 3 The packaging set 200 includes a packaging cushioning structure 100 and a packaging box 3.

Since this packaging set 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the packaging box 3 is provided with a packaging cavity 3a, the packaging cushioning structure 100 is accommodated and limited in the packaging cavity 3a, and the cushioning member 2 abuts against the inner wall of the packaging cavity 3a.
[0037] The packaging set 200 of this utility model consists of a packaging cushioning structure 100 and a packaging box 3. The packaging box 3 has a packaging cavity 3a, the size and shape of which match the packaging cushioning structure 100, allowing the packaging cushioning structure 100 to be tightly contained and confined within the packaging cavity 3a. The design of the cushioning element 2 allows it to tightly abut against the inner wall of the packaging cavity 3a, so that when the packaging box 3 is subjected to external impact, the cushioning element 2 can absorb and disperse the impact force immediately, protecting the product inside the packaging cavity 3a. This design not only fully utilizes the structural advantages of the cushioning element 2 mentioned in the above embodiments, but also further enhances the overall stability of the packaging through the tight integration of the packaging box 3 and the cushioning structure, ensuring that the product receives comprehensive protection during transportation and storage.
