[0041] Any feature disclosed in this specification, unless specifically stated otherwise, may be replaced by other equivalent or similar features. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features. Throughout this specification, the same reference numerals indicate the same elements.

[0042] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0043] This embodiment proposes a battery pack packaging device that can simultaneously package a large number of battery packs while ensuring good support strength and cushioning effect. Simultaneously, it reduces transportation and recycling costs. Specifically, the battery packs can be lithium batteries. This packaging device is primarily used for sea freight packaging of battery packs; however, the specific type of battery pack and transportation method are not limited here.

[0044] Specifically, such as Figure 1 and Figure 2As shown, the battery pack packaging device includes a carton body 1, inner liner 2, and separator 3; wherein, multiple inner liner 2 are arranged along the Z-axis inside the carton body 1, and multiple spaced-apart receiving cavities 21 are formed in each inner liner 2, and one battery pack 10 is placed in one receiving cavity 21; a separator 3 is arranged between two adjacent inner liner 2, and the carton body 1, inner liner 2, and separator 3 are all made of corrugated cardboard.

[0045] Compared with the prior art, the battery pack packaging device in this embodiment changes the packaging method of the battery pack 10. By arranging multiple inner liner members 2 along the Z-axis inside the carton body 1, the inner liner members 2 form multiple spaced-apart receiving cavities 21, and one battery pack 10 is placed within each receiving cavity 21, so that a large number of battery packs 10 can be packaged through multiple inner liner members 2 and multiple receiving cavities 21 of each inner liner member 2, resulting in a high loading rate of battery packs 10. At the same time, a separator 3 is arranged between two adjacent inner liner members 2 to isolate the battery packs 10 between each inner liner member 2, ensuring that the battery packs 10 in each inner liner member 2 do not affect each other. In addition, the separator 3 can also improve the structural stability of each inner liner member 2, thereby improving the battery pack 10's performance during transportation. The impact resistance of the inner liner 2 ensures high support strength for the battery pack 10. Furthermore, the use of corrugated cardboard for the carton body 1, inner liner 2, and dividers 3 provides high structural strength for the inner liner 2 and dividers 3, better supporting the battery pack 10, while also reducing their weight for lightweight transportation. Additionally, the lower price and recycling costs of cardboard result in lower overall costs for the carton body 1, inner liner 2, and dividers 3, and they are easier to recycle, thus reducing transportation and recycling costs for the battery pack packaging. Moreover, the carton body 1, inner liner 2, and dividers 3 provide good cushioning for the battery pack 10, resulting in effective protection.

[0046] Furthermore, such as Figure 1 As shown, the battery pack packaging device also includes a limiting member 4. The inner liner 2 is provided with limiting members 4 on opposite sides on the X-axis. On the one hand, the limiting member 4 can limit the position of the inner liner 2 in the carton 1, ensuring the accuracy and stability of the position of the inner liner 2 in the carton 1. On the other hand, the limiting member 4 can enhance the structural stability of the inner liner 2, thereby improving the impact resistance of the inner liner 2 during transportation.

[0047] In this embodiment, as Figure 1As shown, the inner liner 2 has two limiting members 4 on opposite sides of the X-axis, that is, four limiting members 4 are provided on the outer periphery of each inner liner 2, thereby better enhancing the structural stability of the inner liner 2 through the four limiting members 4. The limiting member 4 can specifically be a limiting plate structure. Here, the specific structure of the limiting member 4 is not limited, as long as it can provide limiting and structural support functions.

[0048] Specifically, the limiting member 4 is made of honeycomb paperboard. On the one hand, this makes the limiting member 4 less expensive and lighter, and also easier to recycle, making it more economical and environmentally friendly. On the other hand, it gives the limiting member 4 a certain structural strength, thereby ensuring that the limiting member 4 can enhance the structural stability of the inner liner 2. In this embodiment, the limiting member 4 is specifically made of 30mm thick honeycomb paperboard.

[0049] Furthermore, such as Figure 1 As shown, the battery pack packaging device also includes a support top plate 5, which is disposed between the inner top of the carton body 1 and the uppermost inner liner 2. The support top plate 5 can offset part of the compression of each battery pack 10 device when the whole carton is stacked, so that the support top plate 5 can distribute the pressure applied to the inner liner 2, thereby better protecting each inner liner 2 inside the carton body 1.

[0050] Specifically, the supporting top plate 5 is made of honeycomb paperboard. On the one hand, this makes the supporting top plate 5 less expensive and lighter, and also easier to recycle, making it economical and environmentally friendly. On the other hand, it gives the supporting top plate 5 a certain structural strength, thereby ensuring that the pressure applied to the inner liner 2 can be distributed through the supporting top plate 5. In this embodiment, the supporting top plate 5 specifically uses 30mm thick honeycomb paperboard.

[0051] Furthermore, such as Figure 1 As shown, in this embodiment, three inner linings 2 are provided inside the carton 1, so that the overall size of the formed battery pack packaging device is 1135mm*965mm*706mm. This ensures that the overall strength of the formed battery pack packaging device can meet the requirements of stacking three layers in the container, and enables the entire battery pack packaging device to achieve the maximum loading rate in both 40-foot and 20-foot containers, thereby achieving the optimal transportation cost for the battery pack 10.

[0052] Specifically, such as Figure 1 As shown, the carton body 1 includes an upper cover 11, a side panel 12, and a lower cover 13. The side panel 12 is disposed on the lower cover 13, and the upper cover 11 is disposed on the side panel 12 to form a complete carton body 1. The supporting top plate 5 is disposed between the upper cover 11 and the uppermost inner lining 2.

[0053] Furthermore, such as Figure 1 As shown, the battery pack packaging device also includes a tray 6, which is located at the bottom of the lower cover 13 of the carton 1. The tray 6 provides stable support for the entire carton 1, which is beneficial for stacking the entire battery pack packaging device inside the container. Furthermore, the tray 6 is made of plywood, which provides high structural strength and ensures good support for the carton 1.

[0054] Specifically, such as Figures 1 to 4 As shown, the inner liner 2 includes a first cutter clip 22, a second cutter clip 23, and a third cutter clip 24; wherein, at least three first cutter clips 22 are fitted together to form a first cutter clip group 25, with the slots of two adjacent first cutter clips 22 in the first cutter clip group 25 facing downwards and the slot of the other first cutter clip 22 facing upwards; at least two second cutter clips 23 are fitted together to form a second cutter clip group 26, with the slots of both second cutter clips 23 in the second cutter clip group 26 facing upwards; a plurality of third cutter clips 24 are arranged at intervals along the X-axis, with the opposite ends of the third cutter clips 24 on the Y-axis respectively inserted into two groups of first cutter clip groups 25, and the middle part of the third cutter clips 24 inserted into at least two groups of second cutter clip groups 26; thereby, the inner liner 2 with multiple receiving cavities 21 can be formed through the mutual insertion and cooperation of the first cutter clips 22, the second cutter clips 23, and the third cutter clips 24. The limiting member 4 is disposed on the side of the third cutter card 24 on the X-axis, and the limiting member 4 is located between the adjacent first cutter card group 25 and second cutter card group 26. In this embodiment, three first cutter cards 22 are attached together to form the first cutter card group 25, and two second cutter cards 23 are attached together to form the second cutter card group 26.

[0055] In this embodiment, as Figures 2 to 4 As shown, in an inner liner 2, there are six first blade clips 22, and three first blade clips 22 form a first blade clip group 25, that is, two first blade clip groups 25 are formed; there are four second blade clips 23, and two second blade clips 23 form a second blade clip group 26, that is, two second blade clip groups 26 are formed; there are six third blade clips 24, so that ten receiving cavities 21 can be formed by the interlocking and cooperation of the two first blade clip groups 25, the two second blade clip groups 26, and the six third blade clips 24, so that ten battery packs 10 can be installed simultaneously in an inner liner 2.

[0056] It is worth noting that the specific shape and number of the first blade clip 22, the second blade clip 23, and the third blade clip 24 are not limited, and need to be determined according to the shape and quantity of the battery pack 10. Furthermore, in other embodiments, the inner liner 2 may include a fourth blade clip or even more blade clips. Here, there is no specific limitation, as long as the insertion and cooperation between the various blade clips can form as many receiving cavities 21 as possible.

[0057] Furthermore, such as Figures 3 to 7 As shown, a plurality of first slots 221 are spaced apart on the first blade holder 22, a plurality of second slots 231 are spaced apart on the second blade holder 23, and a plurality of spaced third slots 241 and a plurality of spaced fourth slots 242 are spaced apart on the third blade holder 24. A third slot 241 is inserted into each aligned second slot 231 in a set of second blade holders 26, and a fourth slot 242 is inserted into the first slot 221 with the slot opening facing upward in a set of first blade holders 25.

[0058] Specifically, such as Figure 3 and Figure 7 As shown, the third blade holder 24 has L-shaped plates 243 protruding from both ends on the Y-axis. The short plate 2432 of the L-shaped plate 243 is connected to the end of the third blade holder 24 on the Y-axis. The gap between the long plate 2431 of the L-shaped plate 243 and the end of the third blade holder 24 on the Y-axis forms the aforementioned fourth slot 242. The first slots 221 of the first blade holder group 25 with their slots facing downwards are inserted into the long plate 2431 of the L-shaped plate 243.

[0059] It is worth noting that, such as Figures 5 to 7 As shown, six first slots 221 are formed in the first slot 22, six second slots 231 are formed in the second slot 23, and two third slots 241 and two fourth slots 242 are formed in the third slot 24. The specific number of slots formed on each slot is not limited here and needs to be determined according to the packaging requirements and specific structural layout of the battery pack 10.

[0060] Furthermore, such as Figures 2 to 6 As shown, avoidance slots 27 are respectively provided on the first blade card 22 and the second blade card 23. The avoidance slots 27 are connected to the receiving cavity 21 to avoid the dust cover of the battery pack 10. There is an avoidance slot 27 between two adjacent first slots 221 and between two adjacent second slots 231. That is, a set of avoidance slots 27 aligned on each first blade card 22 in a set of first blade card groups 25 and a set of avoidance slots 27 aligned on each second blade card 23 in a set of second blade card groups 26 are connected in a receiving cavity 21 to ensure a good avoidance effect on the dust cover of the battery pack 10 in each receiving cavity 21.

[0061] The battery pack packaging device in this embodiment uses an inner liner 2 formed by the interlocking of a first cutter 22, a second cutter 23, and a third cutter 24. This inner liner 2 accommodates and isolates each battery pack 10, providing cushioning and withstanding stacking pressure to effectively protect the battery packs 10. Furthermore, four limiting members 4 are provided around the outer periphery of each inner liner 2 to enhance its stability and increase its impact resistance during transportation. Moreover, the individual inner liner 2s within the carton 1 and the respective accommodating cavities 21 within each inner liner 2 allow for the packaging of a large number of battery packs 10, thereby increasing the loading rate of the battery packs 10. Additionally, except for the pallet 6, which is made of plywood, all other components in the entire battery pack packaging device are made of cardboard, resulting in lower production costs, lower transportation costs, and lower recycling costs for the battery packs 10. This achieves economic optimization for the transportation of the battery packs 10, demonstrating good economic and environmental performance.

[0062] The above description is only a preferred embodiment of this utility model.
