Description

Technical Field

[0001] This utility model relates to the field of battery packaging technology, and in particular to a battery packaging structure. Background Technology

[0002] In the storage and transportation of new energy batteries, especially lithium-ion batteries, specialized packaging solutions are typically required to protect them from mechanical stresses such as impacts, compression, and vibrations. Existing common packaging solutions often employ a single foamed material, such as pallets or liners made of expanded polystyrene or expanded polyethylene.

[0003] Publication number CN206395075U discloses a lead-acid battery tray packaging. However, in this packaging design, the contact between the packaging structure and the insulating sheet on top of the battery, as well as the blue film covering the battery, is typically hard or rigid. Under continuous transport vibration, the packaging material will repeatedly rub against the surface of the battery cell, which can easily lead to wear of the top insulating sheet or a large area of ​​the blue film. This not only affects the product's appearance but may also seriously affect the performance of the insulating sheet.

[0004] Therefore, a battery packaging structure is proposed to solve the technical problem that existing packaging solutions cannot effectively protect the insulating sheet and the blue film covering the battery. Utility Model Content

[0005] In view of this, the present invention proposes a battery packaging structure that solves the technical problem that existing packaging solutions cannot effectively protect the insulating sheet and the blue film covering the battery.

[0006] This utility model proposes a battery packaging structure, including a first tray, a support member, and a second tray arranged sequentially along a predetermined direction, wherein the predetermined direction is the extension direction of vertical stacking of batteries; The first tray is provided with a plurality of slots, the inner contour of which is adapted to the outer contour of the battery; The second tray covers the topmost battery, and the support member abuts between the first tray and the second tray along the predetermined direction to maintain a predetermined gap between the second tray and the topmost battery.

[0007] Based on the above technical solutions, preferably, the second tray has several cover grooves on the side near the battery; The supporting member includes several segments, which are disposed on the second tray. The two ends of the segments abut against the first tray and the second tray respectively. The segments divide the several cover grooves into several cover cavities, and the inner contour of the several cover cavities is adapted to the outer contour of the battery.

[0008] Based on the above technical solutions, preferably, the second tray is provided with a plurality of snap-fit ​​grooves, the plurality of snap-fit ​​grooves are orthogonally arranged with the plurality of cover grooves, and the inner contours of the plurality of snap-fit ​​grooves correspond to and adapt to the outer contours of the plurality of segmented parts.

[0009] Based on the above technical solutions, preferably, the second tray is divided into at least two parts along the length extension direction of the cover groove.

[0010] Based on the above technical solutions, preferably, the second tray is a closed-cell foam material.

[0011] Based on the above technical solutions, preferably, the battery is divided into several layers; The first tray includes a receiving tray and several transfer trays. The receiving tray is located at the bottom layer of the battery. The receiving tray has a groove on one side that receives the battery. The transfer tray is located between the batteries on adjacent sides. One side of the transfer tray covers the battery, and the other side of the transfer tray receives the battery. Several limiting grooves are provided on both sides of the transfer tray. The inner contour of the several limiting grooves is adapted to the outer contour of the battery.

[0012] Based on the above technical solutions, preferably, the plurality of limiting grooves on both sides of the turntable are arranged orthogonally to each other.

[0013] Based on the above technical solution, preferably, the first tray further includes several flexible layers, which are respectively disposed on one side of the battery covered by several transfer discs, and are respectively attached to the limiting groove.

[0014] Based on the above technical solutions, preferably, the flexible layer includes a vacuum forming layer and a flexible woven fabric layer.

[0015] Based on the above technical solutions, preferably, the range of the predetermined gap is from 0.5mm to 10mm.

[0016] The battery packaging structure provided by this utility model has the following advantages compared with the prior art: 1. The supporting components form a sturdy supporting frame between the first and second trays, and maintain a predetermined gap between the second tray and the topmost battery, thereby preventing the second tray from contacting the battery during transportation, thus completely preventing the battery packaging structure from wearing down the insulating sheet, thereby improving the protection of the battery. 2. The two ends of several segmented pieces abut against the first tray and the second tray respectively.

[0026] The technical solution will now be explained. In existing packaging solutions, especially between the packaging structure and the insulating sheet on top of the battery, as well as the blue film encasing the battery, there is usually hard or rigid contact. Under continuous transportation vibration, the packaging material will repeatedly rub against the surface of the battery cell, easily leading to wear of the top insulating sheet or a large area of ​​the blue film. This not only affects the product's appearance but may also seriously affect the performance of the insulating sheet. In view of this, if... Figure 1 and Figure 2As shown, this utility model provides a battery packaging structure, including a first tray 1, a support member 2 and a second tray 3 arranged sequentially along a predetermined direction, the predetermined direction being the extension direction of the vertical stacking of batteries 100; The first tray 1 is provided with a plurality of slots 101, the inner contour of the slots 101 being adapted to the outer contour of the battery 100. The second tray 3 covers the topmost battery 100, and the support member 2 abuts between the first tray 1 and the second tray 3 in a predetermined direction so that the second tray 3 and the topmost battery 100 maintain a predetermined gap.

[0027] The support member 2 forms a sturdy support frame between the first tray 1 and the second tray 3, and maintains a predetermined gap between the second tray 3 and the topmost battery 100, thereby preventing the second tray 3 from contacting the battery 100 during transportation, thus completely preventing the battery packaging structure from wearing down the insulating sheet and improving the protection of the battery.

[0028] like Figure 2 and Figure 3 As shown, in order to ensure that the second tray 3 and the battery 100 maintain a stable predetermined gap, the second tray 3 is provided with a number of cover grooves 301 on the side near the battery 100. The support member 2 includes a plurality of segmented parts 21, which are disposed on the second tray 3. The two ends of the plurality of segmented parts 21 abut against the first tray 1 and the second tray 3 respectively along a predetermined direction. The plurality of segmented parts 21 divide the plurality of cover grooves 301 into a plurality of cover cavities 3011, and the inner contour of the plurality of cover cavities 3011 is adapted to the outer contour of the battery 100.

[0029] Specifically, a number of batteries 100 are arranged in a rectangular array, and a number of cover grooves 301 arranged longitudinally are provided on the second tray 3. A number of dividing pieces 21 divide the cover grooves 301 in the transverse direction to form a number of cover cavities 3011, so that the number of cover cavities 3011 correspond to the number of batteries 100.

[0030] The two ends of several segmented pieces 21 abut against the first tray 1 and the second tray 3 respectively. When several covering cavities 3011 are correspondingly covered on several batteries 100, the several covering cavities 3011 are spaced apart from the batteries 100 by a predetermined gap. Therefore, when the second tray 3 is covered on the battery 100, the second tray 3 will not wear down the insulating sheet on the battery 100.

[0031] like Figure 2 As shown, in order to ensure that the segment 21 is stably fixed on the second tray 3, the second tray 3 is provided with a number of snap-fit ​​grooves 302. The number of snap-fit ​​grooves 302 are orthogonally arranged with a number of cover grooves 301, and the inner contour of the number of snap-fit ​​grooves 302 corresponds to the outer contour of the number of segment 21.

[0032] The second tray 3 is provided with a corresponding snap-fit ​​groove 302. The divider 21 is set on the second tray 3 by snap-fit, which can make the divider 21 stably fixed.

[0033] It is worth mentioning that the batteries 100 are spaced apart in the horizontal and vertical directions, and the gaps between the several dividing pieces 21 and the adjacent two batteries 100 are adapted to ensure that the several cover cavities 3011 can be stably fitted on the batteries 100 and ensure that the batteries 100 and the cover cavities 3011 are stably fitted together, and there will be no problem of the batteries 100 shaking inside the cover cavities 3011.

[0034] like Figure 1 As shown, the second tray 3 is divided into at least two parts along the length extension direction of the cover groove 301.

[0035] The second tray 3 is divided into two parts. This modular design significantly reduces the size of each individual component, resulting in more uniform material flow and consistent cooling and shrinkage within the mold. This greatly reduces production difficulty and complexity, thereby improving production efficiency and the first-pass yield. The modular design allows operators to install each part individually, making it easier and more precise to position each section. Even if one part is slightly off-center, adjusting that part will not affect the other, offering greater tolerance for error and making installation faster and more reliable.

[0036] like Figure 3 As shown, the second tray 3 is a closed-cell foam material.

[0037] Specifically, the second tray 3 is made of foamed polyethylene (EPE), a closed-cell foamed material that is flexible and impact-resistant, providing a good cushioning effect. The dividing piece 21 is also made of foamed polyethylene and is directly inserted between the gaps of the batteries 100 to protect the contact surface with the batteries 100 and to cushion the impact of shaking.

[0038] like Figure 2 As shown, battery 100 is divided into several layers; The first tray 1 includes a receiving tray 11 and several intermediate trays 12. The receiving tray 11 is located on the bottom layer of the battery 100. A groove 101 is provided on one side of the receiving tray 11 that receives the battery 100. The intermediate trays 12 are located between adjacent batteries 100. One side of the intermediate tray 12 covers the battery 100, and the other side of the intermediate tray 12 receives the battery 100. Several limiting grooves 1201 are provided on both sides of the intermediate tray 12. The inner contour of the several limiting grooves 1201 is adapted to the outer contour of the battery 100.

[0039] When the battery 100 is divided into several layers, the bottom layer of battery 100 is supported by the receiving plate 11, and the intermediate plate 12 is placed on top of the bottom layer of battery 100. The top of the intermediate plate 12 supports the adjacent battery 100, and several layers of battery 100 are supported by several intermediate plates 12 in sequence to ensure that several layers of battery 100 can be stably stacked and piled up vertically.

[0040] like Figure 2 As shown, in order to ensure the stability of several layers of batteries 100 after stacking, several limiting grooves 1201 on both sides of the turntable 12 are orthogonally arranged.

[0041] The orthogonal design of the limiting grooves 1201 on both sides of the turntable 12 allows the adjacent two layers of batteries 100 to be placed in a staggered manner, thereby ensuring the stability of the overall battery pack after stacking and avoiding external impacts from affecting the stability of several batteries after stacking.

[0042] like Figure 4 and Figure 5 As shown, in order to further improve the protection of the battery 100, the first tray 1 also includes several flexible layers 13, which are respectively disposed on one side of the battery 100 by several intermediate turntables 12, and are respectively attached to the limiting groove 1201.

[0043] When the transfer plate 12 is mounted on top of the battery 100, the transfer plate 12 uses a flexible layer 13 to contact the insulating sheet on top of the battery 100 to prevent the transfer plate 12 from abrading the insulating sheet, thereby improving the protection of the battery 100 by the transfer plate 12.

[0044] like Figure 5 As shown, the flexible layer 13 includes a thermoforming layer and a flexible fabric layer.

[0045] Vacuum forming is a process of processing high-molecular polymer plastic materials, which have plasticity. Common materials include PVC, PET, PP, and PS. PVC material is heated and softened, then filled into a corresponding mold to form a specific shape. For example, the PVC material is processed into a shape that matches the inner contour of several limiting grooves 1201. A flexible fabric layer is adhered to the surface of the PVC material. Finally, the PVC material is bonded to the inner wall of the limiting grooves 1201, and the flexible fabric layer is brought into contact with the battery's insulating sheet, thereby improving the protection of the battery 100 by the turntable 12.

[0046] like Figure 3 As shown, in order to ensure that the second tray 3 does not come into contact with the battery 100, the predetermined gap ranges from 0.5mm to 10mm.

[0047] The predetermined gap of 0.5mm is a safety design threshold. It takes into account the unavoidable slight shaking of batteries during transportation, minor deformation of packaging materials, and settling caused by stacking pressure. Even with these factors, a 0.5mm gap ensures that, under the worst-case scenario, the upper pallet will not come into contact with the most sensitive top insulating sheet of the battery. If the gap is less than 0.5mm, the predetermined gap design may fail due to manufacturing tolerances and material deformation. In standardized shipping containers, space is an extremely valuable resource. Excessive gaps, such as those exceeding 10mm, significantly reduce the number of batteries that can be transported per shipment, increasing unit transportation costs. A 10mm gap provides sufficient buffer space while having minimal impact on the overall stacking height, ensuring excellent space utilization.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
