Description

Technical Field

[0001] This utility model relates to the field of logistics packaging technology, and more specifically, to a packaging pallet and battery cell transport packaging. Background Technology

[0002] In the field of cargo packaging and transportation, especially for the transport of high-value, highly sensitive battery cells, the safety and reliability of pallets, as the carrier, directly affect the integrity of the goods. To ensure that battery cells are protected from slippage damage caused by the dynamic behavior of vehicles such as sudden braking and turning during transportation, the industry generally adopts external mechanical fixing methods, mainly including wrapping with plastic stretch film and securing with nylon straps. These methods attempt to stabilize the position of the goods through encapsulation and restraint. However, the essence of existing anti-slip solutions is to rely on the passive constraint of external materials. Their anti-slip performance is affected by external constraint conditions such as the strength of external materials and preload, and has obvious limitations. For example, stretch film may loosen under long-term vibration, and straps face the risk of wear and breakage. Especially under extreme conditions, such as sudden braking with high deceleration, simply relying on external material constraints is often insufficient to effectively prevent the slow "creep" displacement of the goods. The anti-slip effect is unstable and limited, posing a potential threat to the transportation safety of valuable battery cells. Utility Model Content

[0003] The main purpose of this utility model is to provide a packaging pallet and battery cell transport packaging that can solve the problem that existing packaging pallet and battery cell transport packaging solutions rely on the passive constraints of external materials, resulting in unstable and limited anti-slip effects.

[0004] To achieve the above objectives, according to one aspect of the present invention, a packaging tray is provided, including a supporting part and a supporting bottom cover, the supporting bottom cover being stacked on the supporting part, and an anti-slip layer being provided between the supporting part and the supporting bottom cover, the anti-slip layer forming an anti-slip connection with both the supporting part and the supporting bottom cover.

[0005] Furthermore, the anti-slip layer includes an anti-slip mat, and a connecting layer is provided between the anti-slip mat and the supporting part.

[0006] Furthermore, the connecting layer is an adhesive layer, which is applied to the side of the anti-slip mat facing the support portion.

[0007] Furthermore, an adhesive layer is applied to the side of the support portion facing the anti-slip mat.

[0008] Furthermore, the anti-slip layer is an anti-slip coating, which is disposed between the supporting bottom cover and the supporting part, and the anti-slip coating is sprayed or scraped onto at least one of the supporting bottom cover and the supporting part.

[0009] Furthermore, the anti-slip coating includes spray-applied polyurethane elastomers, neoprene rubber adhesive coatings, pressure-sensitive synthetic rubber sheets, water-based acrylic emulsion coatings doped with wear-resistant particles, or epoxy resin coatings doped with friction-increasing fillers.

[0010] Furthermore, the bottom of the support part is also provided with a support part and a first limiting groove. Multiple support parts are arranged at intervals, and the first limiting groove is between two adjacent support parts and is set along the extension direction of the support part. The first limiting groove can limit the packaging strap.

[0011] Furthermore, the support part includes multiple spaced support columns, and the support part is also provided with a second limiting groove. The second limiting groove is between two adjacent support columns and extends in a direction perpendicular to the first limiting groove. The second limiting groove can limit the packaging straps.

[0012] According to another aspect of the present invention, a battery cell transport package is also provided, including the aforementioned packaging pallet.

[0013] Furthermore, the cargo packaging also includes a packaging cover and a packaging box. The packaging box is installed on a packaging pallet, and the packaging cover is located on top of the packaging box. When the bottom of the supporting part is provided with a first limiting groove, the packaging cover is provided with a third limiting groove corresponding to the first limiting groove. The cargo packaging also includes packaging straps, which are tied to the outside of the cargo packaging and snapped into the first limiting groove and the third limiting groove.

[0014] Furthermore, when the supporting part is also provided with a second limiting groove, the packaging cover is also provided with a fourth limiting groove corresponding to the second limiting groove. The fourth limiting groove is perpendicular to the third limiting groove. The packaging strap is tied to the outside of the goods packaging and is locked in the fourth limiting groove and the second limiting groove.

[0015] Applying the technical solution of this utility model, the support section serves as the basic structure of the pallet, directly contacting and bearing the goods. Its design must fully consider load-bearing capacity and structural stability to ensure good performance under various transportation conditions. The support bottom cover is stacked on the support section, packaging and securing the goods from the bottom, preventing fragile items such as battery cells from directly contacting the rough support section, thereby improving the safety and stability of the goods. During transportation, goods are prone to positional shifts due to sudden braking or violent dynamic behavior of the vehicle, especially for heavy secondary batteries. By placing the anti-slip layer between the support section and the bottom cover, and forming an anti-slip connection with both sections, the relative sliding resistance between the support section and the bottom cover is significantly increased. This adds sliding constraints to the internal structure of the packaging pallet, reducing reliance on passive constraints from external materials such as cable ties. This provides stable anti-slip performance for the goods. As the weight of the transported goods increases, the static friction force generated by the anti-slip layer between the support section and the bottom cover also increases, further improving the anti-slip effect. This reduces the risk of goods shifting during transportation and ensures the safety of the goods. Attached Figure Description

[0032] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] See also Figures 1 to 13 As shown, this utility model provides a packaging pallet, which includes a supporting part 1 and a supporting bottom cover 21. The supporting bottom cover 21 is stacked on the supporting part 1, and an anti-slip layer 3 is provided between the supporting part 1 and the supporting bottom cover 21. The anti-slip layer 3 forms an anti-slip connection with both the supporting part 1 and the supporting bottom cover 21.

[0034] In the above technical solution, the support part 1 serves as the basic structure of the pallet, directly contacting and bearing the goods. Its design must fully consider load-bearing capacity and structural stability to ensure good performance under various transportation conditions. The support bottom cover 21 is stacked on the support part 1, packaging and securing the goods from the bottom, preventing fragile goods such as battery cells from directly contacting the rough support part 1, thereby improving the safety and stability of the goods. During transportation, goods are prone to positional shifts due to sudden braking or violent dynamic behavior of the vehicle, especially for heavy secondary batteries. The anti-slip layer 3 is placed between the support part 1 and the support bottom cover 21, and forms an anti-slip connection with both the support part 1 and the support bottom cover 21. This significantly increases the resistance to relative sliding between the support part 1 and the support bottom cover 21, adding sliding constraints to the internal structure of the packaging pallet and reducing reliance on passive constraints from external materials such as cable ties. This provides stable anti-slip performance for the goods. As the weight of the transported goods increases, the static friction force brought by the anti-slip layer 3 between the support part 1 and the support bottom cover 21 also increases, further improving the anti-slip effect. This reduces the risk of goods moving during transportation and ensures the safety of the goods.

[0035] In one embodiment of the present invention, the anti-slip layer 3 includes an anti-slip pad 31, and a connecting layer 4 is provided between the anti-slip pad 31 and the supporting part 1.

[0036] In the above technical solution, the anti-slip mat 31, made of elastic anti-slip materials such as neoprene rubber and synthetic rubber, serves as the anti-slip layer 3, significantly improving the coefficient of friction of the contact surface between the support part 1 and the support bottom cover 21, effectively preventing any possible slippage of goods during transportation. The connecting layer 4 is crucial to ensuring that the anti-slip mat 31 can be firmly attached to the support part 1 or the support bottom cover 21. The connecting layer 4, which can be an adhesive layer or other types of adhesive, is placed between the anti-slip mat 31 and the support part 1. On the one hand, it provides sufficient adhesive force to ensure that the anti-slip mat 31 remains tightly bonded to the support part 1 or the support bottom cover 21 under various transportation conditions, preventing it from detaching due to vibration, impact, or other factors. On the other hand, the connecting layer 4 also provides a certain buffering effect, absorbing pressure and impact from the goods, extending the service life of the anti-slip mat 31 and the entire pallet.

[0037] In one embodiment of this utility model, the connecting layer 4 is an adhesive layer, which is applied to the side 311 of the anti-slip pad 31 facing the support portion 1 or the side 11 of the support portion 1 facing the anti-slip pad 31.

[0038] In the above technical solution, the adhesive layer, as a strong bonding medium, ensures that the anti-slip mat 31 is firmly attached to the surface of the support portion 1. The selection and application of the adhesive layer must meet specific technical requirements, such as good bonding strength, durability, and the ability to adapt to different temperatures and humidity levels, to ensure that its connection performance is maintained in various transportation environments and to prevent the anti-slip mat 31 from falling off during use. The application of the adhesive layer greatly enhances the stability of the anti-slip layer 3, which means that even under extreme transportation conditions, the anti-slip mat 31 can maintain its position, providing a continuous and stable frictional force between the anti-slip mat 31 and the support base cover 21, thereby reducing the risk of goods sliding during transportation.

[0039] In one embodiment of the present invention, the anti-slip layer 3 is an anti-slip coating 32, which is disposed between the supporting bottom cover 21 and the supporting part 1. The anti-slip coating 32 is sprayed or scraped onto at least one of the supporting bottom cover 21 and the supporting part 1.

[0040] In the above technical solution, the anti-slip coating 32 acts directly on the contact interface between the support bottom cover 21 and the support part 1, achieving the anti-slip function by increasing the surface friction coefficient. The design of spraying or scraping the anti-slip coating 32 onto either the support bottom cover 21 or the support part 1 provides operational flexibility. On the one hand, this construction method is more flexible than pre-installing anti-slip mats, allowing adjustment of the coating's coverage and thickness according to actual needs; on the other hand, it eliminates the need for additional mechanical fixing or pasting steps, simplifying pallet assembly and cargo loading processes and improving logistics efficiency. The application method of the anti-slip coating 32 is highly adaptable and compatible. It is not only suitable for different materials of the support bottom cover 21 and the support part 1, but can also work in conjunction with other external fixing methods such as packaging straps to form a multi-layered cargo stabilization system, improving the anti-slip performance and stability of the entire packaging pallet system.

[0041] In one embodiment of this utility model, the maximum deceleration of the truck is 0.3g~0.4g. Taking the maximum deceleration a as twice the midpoint, which is 0.7g, when the packaging specifications require the weight of a single pallet to be less than 1.2 tons, assuming the cargo mass m = 1200kg, to prevent the cargo of mass m = 1200kg from sliding during sudden braking at the maximum deceleration a = 0.7g, the resulting inertial force F_inertia = m × a = 8232N. The normal force F of the cargo on the pallet... 正 =m×g=11760N. According to the static friction formula F_friction=μ×F 正The critical condition for the system to not slip is F_friction ≥ F_inertia, which leads to the derivation of the minimum static friction coefficient required at the interface, μ_min = a / g = 0.7. Therefore, the core of this scheme is to ensure that the coating friction coefficient μ > 0.7. Simultaneously, the average shear stress on the contact surface is calculated as τ = F_inertia / A ≈ 7.6 kPa, where A is the contact area between the goods and the pallet.

[0042] To ensure absolute safety, the coating system must meet three strength requirements: 1) the adhesion strength between the coating and EPS must be greater than τ; 2) the adhesion strength between the coating and the wooden pallet must be greater than τ; and 3) the cohesive strength of the coating itself must be greater than τ. The materials selected in this solution all have strengths in the megapascal (MPa) range, which is more than a hundred times this benchmark value, providing a significant safety margin.

[0043] In one embodiment of this utility model, the anti-slip coating 32 includes a sprayable polyurethane elastomer, a neoprene rubber adhesive coating, a pressure-sensitive synthetic rubber sheet, a water-based acrylic emulsion coating doped with wear-resistant particles, or an epoxy resin coating doped with friction-increasing fillers.

[0044] Based on the core requirement of μ>0.7, the following five feasible coating materials are proposed for the above technical solutions: spray-applied polyurethane elastomer, neoprene rubber adhesive coating, pressure-sensitive adhesive synthetic rubber sheet, water-based acrylic emulsion coating with wear-resistant particles, or epoxy resin coating with friction-increasing fillers. Spray-applied polyurethane elastomer, after curing, forms a tough elastic layer with a friction coefficient of 0.75-0.85, providing high friction and elastic support, effectively resisting impact and vibration, maintaining cargo stability, and ensuring the coating's durability and long-term performance. Neoprene rubber adhesive coating has good initial tack and final bond strength, with a friction coefficient of 0.70-0.80, suitable for rapid installation and high-slip applications, while also providing some environmental adaptability and chemical resistance. Pressure-sensitive adhesive synthetic rubber sheet (SBR / NBR), through pre-forming, provides convenient on-the-go application, with a friction coefficient of 0.75-0.90. Its surface micro-texture enhances friction, making it suitable for scenarios requiring rapid deployment and replacement. Water-based acrylic emulsion coatings with wear-resistant particles are environmentally friendly, making them ideal for green logistics. With a friction coefficient of 0.75-0.90, the mechanical interlocking of the wear-resistant particles significantly improves the friction coefficient, enhancing the coating's wear resistance and anti-fouling capabilities. Epoxy resin coatings with friction-increasing fillers provide extremely high adhesive strength and friction performance. The addition of fillers such as alumina raises the friction coefficient to 0.72-0.82, making them suitable for securing goods under high loads and harsh environmental conditions, ensuring the safety and stability of goods under extreme operating conditions. Each coating material has its unique physical and chemical properties, suitable for different application environments and requirements.

[0045] In one embodiment of this invention, the substrate is first rigorously pretreated using an organic solvent such as isopropanol to thoroughly clean the contact surface between the EPS and the wooden pallet, removing oil stains. Then, the surface is evenly sanded with 180-400 grit sandpaper to increase roughness, and finally, all dust is removed. Next, a coating is applied: this can be done by spraying / scraping (e.g., mixing two-component polyurethane in a specific ratio and applying it evenly to the wooden pallet, controlling the dry film thickness to 0.5-2.0 mm to ensure its strength) or by adhesive bonding (cutting a pre-made rubber sheet, removing the release paper, precisely bonding it to the pre-treated EPS surface, and applying rolling pressure to remove air). Finally, thorough curing is performed: reactive coatings need to be cured at room temperature for at least 24 hours; pressure-sensitive adhesive sheets need to be aged for 24 hours to achieve optimal strength, after which they can be used for load-bearing.

[0046] In one embodiment of the present invention, the bottom of the support portion 1 is further provided with a support portion 5 and a first limiting groove 61. Multiple support portions 5 are arranged at intervals, and the first limiting groove 61 is located between two adjacent support portions 5 and is provided along the extending direction of the support portion 5. The first limiting groove 61 can limit the packaging strap 7.

[0047] In the above technical solution, the spaced-apart support parts 5 not only provide load-bearing function, but also form a frame structure, enhancing the overall rigidity of the support part 1, thereby providing more stable support for the goods above and the support cover 21, ensuring structural stability under various transportation conditions. The first limiting groove 61 is set along the extension direction of the support part 5, providing a longitudinal installation position for the packaging cable tie 7. When the packaging cable tie 7 passes through the first limiting groove 61 and around the goods, the first limiting groove 61 can restrict the lateral movement of the cable tie, preventing the cable tie from loosening or shifting under vibration or impact during transportation, thereby ensuring the stability of the goods.

[0048] In one embodiment of the present invention, the support part 5 includes a plurality of spaced support columns 51, and the support part 1 is also provided with a second limiting groove 62. The second limiting groove 62 is between two adjacent support columns 51 and extends in a direction perpendicular to the first limiting groove 61. The second limiting groove 62 can limit the packaging strap 7.

[0049] In the above technical solution, the support column 51 serves as the pillar at the bottom of the support part 1. Through vertical support at multiple points, it increases the height of the support part 1, reduces the impact of liquids or dust on the goods, and facilitates the connection and transportation of goods by forklifts or cranes through the gap formed between two adjacent support columns 51. The second limiting groove 62 is located between two adjacent support columns 51 and extends in a direction perpendicular to the first limiting groove 61, forming a longitudinal limiting for the packaging strap 7. Together with the anti-slip layer 3, it further improves the stability of the goods and reduces the possibility of slippage and displacement of the goods during transportation.

[0050] In one embodiment of the present invention, a connecting base plate 52 is provided at the end of the support column 51 away from the support part 1. The connecting base plate extends along the length or width direction of the support part 1, and the connecting base plate 52 connects multiple support columns 51.

[0051] In the above technical solution, the connecting base plate 52 connects multiple support columns 51 to form a frame structure, thereby improving the structural strength of the support part 5 and preventing the support columns 51 from breaking or shifting under heavy pressure. In addition, the support part 5 contacts the ground through the connecting base plate 52, which increases the contact area between the support part 5 and the ground compared to contacting the ground only through the support columns 51. This effectively distributes the weight of the goods, avoids stress concentration, and thus improves the reliability and lifespan of the support part 5.

[0052] In one embodiment of the present invention, multilayer battery cells 24 are stacked and installed on a supporting bottom cover 21, a supporting middle cover 22 is provided between two adjacent layers of battery cells 24, and a supporting top cover 23 is provided above the top battery cell 24.

[0053] In the above technical solution, the supporting cover 22, acting as a partition between two adjacent layers of battery cells, not only provides vertical positioning but also serves as a buffer, reducing direct contact between the battery cells and effectively preventing damage caused by vibration or impact. The supporting top cover 23, located at the top of the battery cell stack, isolates the battery cell 24 from the packaging top cover 8, preventing direct contact between the rigid packaging top cover 8 and the battery cell 24 and thus avoiding damage. This further enhances the safety and stability of the battery cells during transportation and reduces the risk of damage to the battery cell 24 due to external pressure.

[0054] See also Figures 1 to 13 As shown, this utility model also provides a battery cell transport packaging, including the packaging pallet of the above embodiment.

[0055] In the above technical solution, by adopting the packaging pallet with an anti-slip layer 3 between the supporting part 1 and the supporting bottom cover 21 in the above embodiment, sliding constraints are added to the internal structure of the packaging pallet, reducing the reliance on passive constraints from external materials such as cable ties, thereby providing stable anti-slip performance for the goods. Furthermore, as the weight of the transported goods increases, the static friction force brought by the anti-slip layer 3 between the supporting part 1 and the supporting bottom cover 21 also increases, further improving the anti-slip effect, thereby reducing the risk of goods moving during transportation and ensuring the safety of the goods.

[0056] In one embodiment of this utility model, the goods packaging also includes a packaging cover 8 and a packaging box 9. The packaging box 9 is installed on a packaging pallet, and the packaging cover 8 is located on the top of the packaging box 9. When the bottom of the supporting part 1 is provided with a first limiting groove 61, the packaging cover 8 is provided with a third limiting groove 63 corresponding to the first limiting groove 61. The goods packaging also includes a packaging cable tie 7, which is tied to the outside of the goods packaging and snapped into the first limiting groove 61 and the third limiting groove 63.

[0057] In the above technical solution, the addition of the packaging cover 8 and the packaging box 9 improves the overall sealing of the packaging, better protecting the relatively fragile and valuable goods such as the battery cells 24 from external environmental factors such as humidity, dust, and collisions, ensuring the goods remain intact during long-distance transportation. When the bottom of the supporting part 1 is provided with a first limiting groove 61, the packaging cover 8 is provided with a third limiting groove 63 corresponding to the first limiting groove 61. The packaging straps 7 can tie and fix the goods to the packaging pallet within the first limiting groove 61 and the third limiting groove 63. The first limiting groove 61 and the third limiting groove 63 are used to limit the packaging straps, preventing them from sliding or shifting to the left or right, thereby improving the firmness and reliability of the binding and fixing. At the same time, the packaging straps pull the goods and the packaging pallet from the outside to the inside, and together with the anti-slip layer 3, further increase the static friction between the goods and the packaging pallet, significantly reducing the possibility of the goods slipping or shifting.

[0058] In one embodiment of this utility model, when the supporting part 1 is also provided with a second limiting groove 62, the packaging cover 8 is also provided with a fourth limiting groove 64 corresponding to the second limiting groove 62. The fourth limiting groove 64 is perpendicular to the third limiting groove 63. The packaging strap 7 is tied to the outside of the goods packaging and is locked in the fourth limiting groove 64 and the second limiting groove 62.

[0059] In the above technical solution, the packaging cable tie 7 can also tie and fix the goods to the packaging pallet in the second limiting groove 62 and the fourth limiting groove 64. The second limiting groove 62 and the fourth limiting groove 64 can limit the packaging cable tie 7 from the direction perpendicular to the first limiting groove 61 and the third limiting groove 63. When multiple packaging cable ties 7 are engaged in these limiting grooves, they can not only firmly fix the goods in the vertical direction, but also provide additional binding force in the horizontal direction. Together with the anti-slip layer 3, it significantly improves the goods' resistance to vibration and impact when facing inertial forces in different directions during transportation.

[0060] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The support part 1 serves as the basic structure of the pallet, directly contacting and bearing the goods. Its design needs to fully consider load-bearing capacity and structural stability to ensure good performance under various transportation conditions. The support bottom cover 21 is stacked on the support part 1, packaging and securing the goods from the bottom, preventing fragile goods such as battery cells from directly contacting the rough support part 1, thereby improving the safety and stability of the goods. During transportation, goods are prone to positional shifts due to emergency braking or violent dynamic behavior of the vehicle, especially for heavy secondary batteries. The anti-slip layer 3 is placed between the support part 1 and the support bottom cover 21, and forms an anti-slip connection with both the support part 1 and the support bottom cover 21. This significantly increases the resistance to relative sliding between the support part 1 and the support bottom cover 21, adding sliding constraints to the internal structure of the packaging pallet and reducing reliance on passive constraints from external materials such as cable ties. This provides stable anti-slip performance for the goods. As the weight of the transported goods increases, the static friction force brought by the anti-slip layer 3 between the support part 1 and the support bottom cover 21 also increases, further improving the anti-slip effect. This reduces the risk of goods moving during transportation and ensures the safety of the goods. By adopting the packaging pallet with an anti-slip layer 3 between the supporting part 1 and the supporting bottom cover 21 in the above embodiment, sliding constraints are added to the internal structure of the packaging pallet, reducing the reliance on passive constraints from external materials such as cable ties. This provides stable anti-slip performance for the goods. Furthermore, as the weight of the transported goods increases, the static friction force brought by the anti-slip layer 3 between the supporting part 1 and the supporting bottom cover 21 also increases, further improving the anti-slip effect. This reduces the risk of goods moving during transportation and ensures the safety of the goods.

[0061] The packaging pallets and battery cell transport packaging described above ensure anti-slip capability from a physical perspective, directly resisting sudden braking with a deceleration of 0.7g, thus solving the pain point of potential failure of traditional methods and achieving inherent safety. Simultaneously, it significantly reduces or even replaces the use of disposable stretch film and strapping, lowering material costs per shipment and reducing plastic pollution at the source, aligning with the development trend of green logistics. Furthermore, it eliminates the cumbersome binding and wrapping process, enabling quick construction and seamless integration into existing packaging or pallet management processes, significantly improving logistics efficiency and facilitating standardization and automation. Moreover, this solution does not alter the overall shape and dimensions of the goods and pallets, does not affect stacking, warehousing, or transportation, and is suitable for various standard scenarios. Finally, this coating method can be used in conjunction with a small amount of strapping to construct a dual anti-slip mechanism of "high-friction interface + mechanical restraint," providing unprecedented ultra-high level protection for high-value goods.
