Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0044] Please combine Figure 1 and Figure 2 ;in, Figure 1 This is a schematic diagram of the structure of the battery packaging box 1 provided in an embodiment of the present utility model; Figure 2 This is an exploded view of the battery packaging box 1 provided in an embodiment of the present invention.

[0045] An embodiment of this utility model provides a battery packaging box 1, which includes a box body 11, a tray 12, and a cover 13. The box body 11 includes a plurality of connected side panels 111, each side panel 111 including a first side 1111 and a second side 1112 disposed opposite to each other along the height direction of the battery packaging box 1. The tray 12 is disposed on the side of the first side 1111 away from the second side 1112, and the tray 12 is inserted into the first side 1111. The cover 13 is disposed on the side of the second side 1112 away from the second side 1111. On one side of the first side 1111, the cover plate 13 covers the box body 11 and extends to the outer periphery of the box body 11. The cover plate 13 is inserted into the first side 1111. The Young's modulus of the side plate 111 is smaller than that of the cover plate 13, thereby simplifying the assembly process of the battery packaging box 1 and improving the convenience of battery packaging and unpacking operations. At the same time, by using the side plate 111 material with a lower Young's modulus, the potential damage to the battery caused by external forces can be effectively reduced, especially during transportation and handling, providing better cushioning protection.

[0046] Specifically, the plurality of side plates 111 enclose a receiving cavity 110 having a first port and a second port, the first port and the second port being disposed opposite to each other, the slab 12 covering the first port, and the cover plate 13 covering the second port.

[0047] It should be noted that, in this embodiment, the height direction of the battery packaging box 1 corresponds to... Figure 1 In the Z direction, the length direction of the battery packaging box 1 corresponds to Figure 1 The X direction in the figure, while the width direction of the battery packaging box 1 corresponds to Figure 1 The Y direction in the above definition can more clearly describe the positional relationship and size distribution of the battery packaging box 1 in three-dimensional space, thereby facilitating the understanding and application of the relevant technical features.

[0048] Furthermore, the number of side plates 111 can be four, with the four side plates 111 arranged around the edge of the base plate 121 to form a receiving cavity 110. The receiving cavity 110 is used to place the battery 2 to be transferred. The battery 2 is placed on the tray 12, ensuring that the battery 2 can be stably placed during transportation. A certain distance is maintained between the battery 2 and the side plates 111 to avoid direct contact, thereby reducing the risk of damage due to external impact or vibration. Simultaneously, the spaced arrangement between the battery 2 and the side plates 111 provides additional buffer space, further enhancing the protection of the battery 2 and ensuring it remains intact during long-distance transportation.

[0049] It should be noted that the structure of the battery packaging box 1 provided in this embodiment does not include the battery 2 to be transported. The battery 2 to be transported mentioned in this embodiment and the accompanying drawings is only for the purpose of describing and explaining the design structure and function of the packaging box. In actual use, the battery 2 to be transported will be placed inside the battery packaging box 1. The design of the battery packaging box 1 is intended to provide effective protection for the battery 2 to be transported, including cushioning, fixing, sealing and other functions, to ensure that the battery is not affected by external impact, vibration or environmental factors during transportation.

[0050] Please continue to combine Figure 1 and Figure 2 In one embodiment, the material of the side panel 111 includes, but is not limited to, one of multi-layer corrugated cardboard, honeycomb cardboard, or other corrugated cardboard. The edge crush strength of the side panel 111 is greater than or equal to 18,000 N / m, and the bursting strength of the side panel 111 is greater than or equal to 40 kgf / cm², thereby simplifying the assembly process of the box 11 structure and improving the convenience of battery packaging and unpacking operations. At the same time, it avoids external forces from damaging the battery 2 to be transported and provides better cushioning protection.

[0051] Specifically, the side panel 111 can be made of 3A corrugated material, which is a type of cardboard with a seven-layer structure, typically composed of three layers of corrugated paper core and four layers of flat cardboard. 3A corrugated material has high strength, excellent compression resistance and impact resistance, and can provide excellent cushioning effect, effectively resisting external forces, thereby protecting the battery 2 to be transported inside the battery packaging box 1 from damage.

[0052] It should be noted that edge crush strength refers to the maximum pressure that the side plate 111 can withstand in the height direction of the battery packaging box 1; burst strength refers to the maximum pressure that the side plate 111 can withstand before breaking during the stress process, which usually reflects the tear resistance and damage resistance of the side plate 111.

[0053] Understandably, by setting the edge compressive strength of the side plate 111 to be greater than or equal to 18,000 N / m, the side plate 111 can withstand strong pressure, preventing deformation or damage caused by external pressure or collision. This ensures that the battery packaging box 1 can maintain structural stability during stacking or transportation, and is not easily deformed by pressure, thus effectively protecting the battery 2 to be transported from external pressure damage. At the same time, by setting the bursting strength of the side plate 111 to be greater than or equal to 40 kgf / cm², the side plate 111 has strong resistance to damage, maintaining its integrity under external forces without being torn. This ensures that the battery packaging box 1 can withstand impact, pulling, or external damage during transportation or handling, maintaining the sealing and protective effect of the battery packaging box 1, and preventing the battery 2 to be transported from being directly damaged by the outside during transportation.

[0054] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ;in, Figure 3 This is an exploded view of the tray 12 provided in an embodiment of the present invention; Figure 4 This is a schematic diagram of the tray 12 provided in an embodiment of the present utility model from a first perspective. Figure 5 This is a structural schematic diagram of the tray 12 provided in an embodiment of the present invention from a second perspective.

[0055] In one embodiment, the pallet 12 includes a base plate 121 and corner guards 122. The base plate 121 is located inside the housing 11, thereby providing stable support for the battery 2 to be transported. At least a portion of the corner guards 122 are arranged around the edge of the side plate 111 away from the base plate 121 and are arranged in a closed loop along the outer periphery of the side plate 111, thereby enhancing the structural stability of the pallet 12 and making the connection between the pallet 12 and the side plate 111 more secure, thus preventing the battery packaging box 1 from deforming or being damaged due to external impact or squeezing during transportation.

[0056] The base plate 121 can be made of wood, which has good load-bearing capacity and pressure resistance, and can effectively support the weight of the battery 2 to be transported, ensuring that the base plate 121 will not bend or deform during transportation; the corner protector 122 can be made of paper corner protector 122, which is an environmentally friendly packaging material made of multiple layers of high-strength kraft paper through pressing and bonding. It has the characteristics of being lightweight and high-strength, easy to process and form, strong pressure resistance, and low cost.

[0057] It is understandable that by using paper corner protectors 122, not only can the overall cushioning performance and impact resistance of the battery packaging box 1 be effectively improved, but the overall weight of the battery packaging box 1 can also be reduced, making it easier to transport and handle; moreover, the paper corner protectors 122 are mainly made of renewable materials, with low production costs and easy recycling, which helps to reduce the cost of the battery packaging box 1, meet environmental protection requirements, and conform to the current trend of green packaging.

[0058] Specifically, the corner protector 122 includes a first corner protector 1221 and a plurality of second corner protectors 1222 connected to each other. The first corner protector 1221 is annular and is disposed on the side of the base plate 121 away from the second side 1112. The first corner protector 1221 is fixedly connected to the base plate 121. The second corner protectors 1222 are disposed on the side of the side plate 111 away from the base plate 121 and are arranged around the edge of the first corner protector 1221, thereby ensuring a tight fit between the base plate 121 and the corner protector 122, enhancing the cushioning performance and structural stability of the tray 12, enabling the tray 12 to effectively disperse external pressure from all directions, reducing the impact of impact on the battery packaging box 1, and thus preventing the box 11 from being damaged by severe impact.

[0059] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 ;in, Figure 6 Provided for the embodiments of this utility model Figure 1 Schematic diagram of the cross-sectional structure at point AA'; Figure 7 Provided for the embodiments of this utility model Figure 6 Enlarged view of point B in the middle.

[0060] In one embodiment, a first slot 1220 is provided between the second corner protector 1222 and the base plate 121, and the first side 1111 is embedded in the first slot 1220 and abuts against the first corner protector 1221, thereby making the installation and disassembly of the side plate 111 more convenient; at the same time, it avoids the risk of loosening that may be caused by the screw or nail connection method used in related technologies, and further reduces the assembly cost.

[0061] Along the height direction of the battery packaging box 1, the depth of the first slot 1220 is equal to the thickness of the base plate 121, and the depth D1 of the first groove is greater than or equal to 15 mm and less than or equal to 18 mm; the height H1 of the second corner protector 1222 is greater than or equal to 70 mm and less than or equal to 80 mm, and the thickness T1 of the second corner protector 1222 is greater than or equal to 5 mm and less than or equal to 6 mm; along the length direction of the battery packaging box 1, the length L1 of the first corner protector 1221 is greater than or equal to 70 mm and less than or equal to 80 mm, thereby improving the load-bearing capacity, stability and ease of assembly of the battery packaging box 1.

[0062] Specifically, the base plate 121 is disposed above the first corner protector 1221 to provide support and load-bearing function, and the base plate 121 can serve as the first boundary of the first slot 1220; the first corner protector 1221 is disposed around the edge of the base plate 121 away from the second side 1112 to support the base plate 121 and enhance the strength of the tray 12, and the first corner protector 1221 can serve as the bottom boundary of the first slot 1220; the second corner protector 1222 is disposed around the edge of the side plate 111 away from the base plate 121 and is disposed in a closed loop along the outer periphery of the side plate 111 to serve as a buffer structure of the side plate 111, and the second corner protector 1222 can serve as the second boundary of the first slot 1220.

[0063] It is understood that the side of the base plate 121 near the second corner protector 1222, the side of the first corner protector 1221 near the base plate 121, and the side of the second corner protector 1222 near the base plate 121 surround each other to form the first slot 1220 circumferentially disposed on the edge of the base plate 121. By embedding the first side 1111 into the first slot 1220, the side plate 111 is limited in the width and length directions of the battery packaging box 1, thereby improving the assembly accuracy and stability of the side plate 111.

[0064] In addition, setting the depth D1 of the first groove to be greater than or equal to 15 mm and less than or equal to 18 mm can provide sufficient fitting force for the tray 12, ensuring that when the first side 1111 is inserted into the first slot 1220, the first side 1111 can form a stable connection with the base plate 121 and the corner guard plate 122, avoiding the problem of the side plate 111 becoming loose due to the first slot 1220 being too shallow, and at the same time avoiding the problem of complex processing and increased cost due to the first slot 1220 being too deep.

[0065] Meanwhile, the height H2 of the base plate 121 is set to be greater than or equal to 15 mm and less than or equal to 18 mm. This ensures that the base plate 121 has sufficient strength to bear the weight of the battery 2 to be transferred, while avoiding material waste and weight increase caused by excessive thickness of the base plate 121, thereby improving the economy and ease of use of the battery packaging box 1.

[0066] Furthermore, the height H1 of the second corner protector 1222 is set to be greater than or equal to 70 mm and less than or equal to 80 mm, and the thickness T1 of the second corner protector 1222 is greater than or equal to 5 micrometers and less than or equal to 6 micrometers, so that the second corner protector 1222 can effectively surround the outer periphery of the side plate 111, thereby improving the impact resistance of the battery packaging box 1. During transportation, the second corner protector 1222 can play a buffering and protective role, reducing the risk of damage to the battery packaging box 1 caused by external impact. The length L2 of the first corner protector 1221 is set to be greater than or equal to 70 mm and less than or equal to 80 mm, which can ensure that the structure of the first corner protector 1221 has sufficient support capacity, increase the contact area between the first corner protector 1221 and the bottom plate 121, so that the connection between the first corner protector 1221 and the bottom plate 121 is stable, thereby improving the strength of the tray 12.

[0067] Please continue to combine Figures 1 to 7 In one embodiment, the pallet 12 further includes a reinforcing component 123 and a supporting component 124. The reinforcing component 123 is disposed on the side of the corner guard 122 away from the base plate 121, and the supporting component 124 is disposed on the side of the reinforcing component 123 away from the corner guard 122, thereby further enhancing the strength, stability and load-bearing capacity of the pallet 12.

[0068] The reinforcing component 123 includes a plurality of first reinforcing members 1231 and two second reinforcing members 1232. The plurality of first reinforcing members 1231 are spaced apart along the length direction of the battery packaging box 1 to provide longitudinal (X direction) support and resistance to deformation. The two second reinforcing members 1232 are spaced apart along the width direction of the battery packaging box 1 to provide lateral (Y direction) support and overall structural stability. The first reinforcing members 1231 are fixedly connected to the inner walls of the two second reinforcing members 1232 to form a grid-like support structure, further improving the pressure resistance and impact resistance of the tray 12.

[0069] Specifically, the plurality of first reinforcing members 1231 includes two first reinforcing sub-members 12311 and a plurality of second reinforcing sub-members 12312. The two first reinforcing sub-members 12311 and the plurality of second reinforcing sub-members 12312 are arranged sequentially at intervals along the length direction of the battery packaging box 1, and the plurality of second reinforcing sub-members 12312 are disposed between the two first reinforcing sub-members 12311.

[0070] Two first reinforcing sub-components 12311 and two second reinforcing sub-components 1232 together form a reinforcing ring 1230. The reinforcing ring 1230 abuts against and overlaps with the side of the first corner guard 1221 away from the base plate 121. The second reinforcing sub-component 12312 is located inside the reinforcing ring 1230, and the second reinforcing sub-component 12312 abuts against the side of the base plate 121 away from the second side edge 1112. This can evenly distribute the pressure on the base plate 121 and avoid pressure concentration that could damage a single area.

[0071] Furthermore, along the thickness direction of the battery packaging box 1, the sum of the thickness of the first reinforcing sub-component 12311 and the thickness of the first corner protector 1221 plate 122 is equal to the thickness of the second reinforcing sub-component 12312, and the side of the second reinforcing sub-component 12312 away from the bottom plate 121 is flush with the side of the first reinforcing sub-component 12311 away from the bottom plate 121, thereby keeping the side of the reinforcing assembly 123 away from the corner protector 122 flat.

[0072] It is understood that the first corner protector 1221 is annular, the second reinforcing member 1232 overlaps with the first corner protector 1221, the first reinforcing sub-member 12311 overlaps with the first corner protector 1221, and the second reinforcing sub-member 12312 does not overlap with the first corner protector 1221 (it should be noted that the "overlap" mentioned in this embodiment does not mean "complete overlap", but rather that there is a certain "overlapping area" between the first reinforcing sub-member 12311 and the first corner protector 1221, forming an effective connection and support). By setting the thickness of the second reinforcing sub-member 12312 to be equal to the sum of the thickness of the first reinforcing sub-member 12311 and the thickness of the first corner protector 1221 plate 122, the side of the reinforcing component 123 away from the corner protector plate 122 can remain flat, thereby enabling the reinforcing component 123 to effectively distribute pressure and improve the stability of the tray 12 when carrying the battery 2 to be transferred.

[0073] Please continue to combine Figures 1 to 7In one embodiment, the first reinforcing sub-component 12311, the second reinforcing sub-component 12312, and the second reinforcing member 1232 can all be wooden strip structures. It is understood that wooden strip structures have high strength and rigidity, can evenly distribute pressure from the outside, reduce local excessive stress, thereby improving the pressure resistance and stability of the pallet 12. At the same time, wooden strip structures have low weight and high environmental friendliness. Compared with other heavy materials, wooden strip structures can reduce transportation and production costs.

[0074] Please continue to combine Figures 1 to 7 In one embodiment, along the length of the battery packaging box 1, the width of the second reinforcing member 1232 is equal to the width of the first corner protector 1221; the width of the first reinforcing sub-member 12311 is equal to the width of the first corner protector 1221, so that the reinforcing ring 1230 and the first corner protector 1221 are completely overlapped, thereby enhancing the stability of the reinforcing ring 1230 and ensuring that the edge portion of the battery packaging box 1 maintains a balanced distribution when subjected to external impact or pressure, avoiding local stress concentration, and thus improving the overall strength of the battery packaging box 1.

[0075] The second reinforcing sub-component 12312 is disposed in the middle part of the base plate 121, and along the length of the battery packaging box 1, the width of the second reinforcing sub-component 12312 is greater than the width of the first reinforcing sub-component 12311, thereby improving the load-bearing capacity of the second reinforcing sub-component 12312.

[0076] It is understandable that, since the second reinforcing sub-component 12312 is disposed corresponding to the middle part of the base plate 121, and the second reinforcing sub-component 12312 abuts against the side of the base plate 121 away from the second side 1112, the second reinforcing sub-component 12312 needs to play a greater supporting role in the entire reinforcing assembly 123; by setting the width of the second reinforcing sub-component 12312 to be greater than the width of the first reinforcing sub-component 12311, the second reinforcing sub-component 12312 can provide a larger supporting surface, thereby effectively dispersing the force from the battery 2 to be transferred above the base plate 121 and the external pressure, reducing the risk of local deformation of the base plate 121.

[0077] Please continue to combine Figures 1 to 7In one embodiment, the support assembly 124 includes a plurality of support portions 1241 and a plurality of support plates 1242. The plurality of support portions 1241 are disposed on the side of the reinforcing assembly 123 away from the corner guard plate 122, and the plurality of support portions 1241 are disposed corresponding to the first reinforcing member 1231 and / or the second reinforcing member 1232 to form a point-to-point support structure, thereby avoiding the problem of local stress concentration due to uneven force distribution. The plurality of support plates 1242 are located on the side of the support portions 1241 away from the corner guard plate 122, and the support plates 1242 cover the support portions 1241, thereby increasing the support area of ​​the support assembly 124 and evenly distributing the pressure, thereby enhancing the stability and pressure resistance of the tray 12.

[0078] Specifically, the plurality of support portions 1241 are provided corresponding to the first reinforcing member 1231 and the second reinforcing member 1232, and the plurality of support portions 1241 are evenly distributed on the reinforcing assembly 123, thereby ensuring that the entire reinforcing assembly 123 can distribute pressure more stably and evenly when subjected to force; for example, the support portion 1241 may correspond to the connection part between each of the first reinforcing member 1231 and the second reinforcing member 1232 (the connection part refers to the part where the first reinforcing member 1231 and the second reinforcing member 1232 abut against each other, support portion 1241 The first reinforcing member 1231 is covered by a support portion 1241, which covers the second reinforcing member 1232, to enhance the structural stability of these connecting parts. In addition, the support portion 1241 can also be provided corresponding to the middle part of each first reinforcing member 1231 and correspond to the support portion 1241 on the connecting part between each first reinforcing member 1231 and second reinforcing member 1232, thereby forming a tightly connected support grid structure, improving the support capacity of the support assembly 124, and further enhancing the load-bearing performance and pressure resistance of the pallet 12.

[0079] The plurality of support plates 1242 can be arranged sequentially along the width direction of the battery packaging box 1, and one support plate 1242 corresponds to a plurality of support parts 1241, and one support plate 1242 covers a plurality of support parts 1241; for example, one support plate 1242 can cover the support parts 1241 at the connection between each first reinforcing member 1231 and the second reinforcing member 1232, and cover the support parts 1241 at the middle part of each first reinforcing member 1231, thereby increasing the support area of ​​the support assembly 124 and evenly distributing the pressure, thereby enhancing the stability and pressure resistance of the tray 12.

[0080] One side of the support plate 1242 is fixedly connected to the support part 1241, and the other side of the support plate 1242 can contact the ground (or other suitable surface, such as the surface of a trailer); wherein, the plurality of support plates 1242 can be arranged sequentially along the width direction of the battery packaging box 1, each support plate 1242 corresponds to a plurality of support parts 1241, and each support plate 1242 covers a plurality of support parts 1241; for example, one support plate 1242 can cover the support part 1241 corresponding to the connection part between the first reinforcing member 1231 and the second reinforcing member 1232, and can also cover the support part 1241 corresponding to the middle part of the first reinforcing member 1231, thereby increasing the support area of ​​the support assembly 124, evenly distributing external pressure, and thus improving the stability and pressure resistance of the tray 12.

[0081] Furthermore, the support part 1241 can adopt a rectangular wooden block structure, which can effectively distribute the force and provide uniform support, so that the tray 12 can remain stable under load; the support plate 1242 can adopt a wooden board structure, which has a large contact area and good pressure resistance, ensuring that the book search support plate 1242 can evenly distribute pressure when under force, and providing a more stable support foundation for the support part 1241.

[0082] Along the length of the battery packaging box 1, the width of the support portion 1241 is equal to the width of the second reinforcing sub-component 12312. The support portion 1241 and the second reinforcing sub-component 12312 are overlapped, thereby ensuring a tight connection between the support portion 1241 and the second reinforcing sub-component 12312, and enhancing the stability and load-bearing capacity of the support portion 1241.

[0083] It should be noted that the "overlap" mentioned in this embodiment does not refer to "complete overlap", but rather to the existence of a certain "overlapping area" between the support portion 1241 and the second reinforcing sub-component 12312. Specifically, among the multiple support portions 1241 provided corresponding to the second reinforcing sub-component 12312, the orthographic projection of the support portion 1241 on the first reinforcing member 1231 is located within the second reinforcing sub-component 12312, thereby forming an effective connection and support.

[0084] It is understood that by overlapping the support portion 1241 with the second reinforcing sub-component 12312, the pressure applied externally to the second reinforcing sub-component 12312 can be effectively dispersed and transmitted, avoiding structural deformation or damage caused by pressure concentration.

[0085] Please continue to combine Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 ;in, Figure 8 This is a schematic diagram of the structure of the support member 14 provided in an embodiment of the present utility model.

[0086] In one embodiment, the tray 12 further includes a plurality of fixing parts 125 located within the box body 11, and the battery packaging box 1 further includes a plurality of supporting members 14 located within the box body 11. The plurality of fixing parts 125 are arranged around the edge of the bottom plate 121 near the second side 1112, and the fixing parts 125 are fixedly connected to the bottom plate 121. One side of the supporting member 14 abuts against the bottom plate 121, and the other side of the supporting member 14 abuts against the cover plate 13. Each supporting member 14 is correspondingly provided with one fixing part 125. A through hole 141 is provided on the side of the supporting member 14 near the bottom plate 121. The fixing part 125 is inserted into the through hole 141, thereby forming a stable internal support frame and further enhancing the pressure resistance and stability of the battery packaging box 1.

[0087] Specifically, the support member 14 has a through hole 141 for insertion and engagement with the fixing part 125. The fixing part 125 is inserted into the through hole 141 to achieve precise positioning of the support member 14 and the fixing part 125. The depth of the through hole 141 is greater than the height of the fixing part 125, thereby ensuring a firm connection between the support member 14 and the fixing part 125.

[0088] It is understood that by setting the support member 14 and the fixing part 125 to be interlocked, the support member 14 is limited in the width and length directions of the battery packaging box 1. One side of the support member 14 abuts against the bottom plate 121, and the other side of the support member 14 abuts against the cover plate 13, thereby limiting the support member 14 in the height direction of the battery packaging box 1. This avoids the support member 14 from loosening or shifting in position due to vibration or impact during transportation, improves the stability of the support member 14, and enables the battery packaging box 1 to withstand greater external pressure, reducing the risk of deformation during transportation. At the same time, the interlocking connection simplifies the installation process of the support member 14 and the fixing part 125, reduces assembly steps and errors, and improves assembly efficiency.

[0089] Please continue to combine Figures 1 to 8In one embodiment, the through hole 141 penetrates the support member 14, which can be a tubular structure. Specifically, the support can be a paper square tube structure, the thickness T2 of the support member 14 is greater than or equal to 3 mm and less than or equal to 5 mm, and the load-bearing capacity of the support member 14 is greater than or equal to 400 kg, thereby meeting the heavy load capacity requirements of the battery packaging box 1 during transportation and storage.

[0090] It should be noted that in this embodiment, the support will adopt a paper square tube structure. Therefore, the thickness of the support member 14 refers to the thickness of its tube wall, that is, the distance between the inner wall and the outer wall of the support member 14. It can be understood that by reasonably setting the thickness of the tube wall, the material usage can be optimized and the weight of the support member 14 can be reduced while meeting the support strength and load-bearing capacity of the support member 14, thereby achieving the lightweight design of the battery packaging box 1.

[0091] In related technologies, the support member 14 is usually made of metal or high-density material. Although it has a high load-bearing capacity, it is heavy and increases the overall transportation cost of the battery packaging box 1. In this embodiment, by using a paper square tube structure as the support member 14, a lightweight design of the support member 14 is achieved. The paper square tube structure can reduce material consumption and meet the sustainable development requirements of green packaging. At the same time, the thickness T2 of the support member 14 is set to be greater than or equal to 3 mm and less than or equal to 5 mm to meet the load-bearing requirement of greater than or equal to 400 kg.

[0092] Specifically, this embodiment takes 10 support members 14 as an example for illustration. The 10 support members 14 are evenly distributed in the box body 11 and form a stable support structure with the side plate 111 and the bottom plate 121, so that the load-bearing weight of the battery packaging box 1 is greater than or equal to 6 tons, thereby meeting the high load-bearing requirements of the battery packaging box 1.

[0093] Please continue to combine Figures 1 to 8 In one embodiment, the fixing part 125 and the support member 14 are both provided corresponding to the reinforcing component 123; wherein, the orthographic projection of the fixing part 125 on the reinforcing component 123 is located within the reinforcing ring 1230, and the orthographic projection of the support member 14 on the reinforcing component 123 is located within the reinforcing ring 1230, thereby further improving the stability of the support member 14 through the support effect of the reinforcing ring 1230.

[0094] Specifically, the orthographic projection of the fixing part 125 on the reinforcing ring 1230 is located within the orthographic projection of the supporting part 1241 on the reinforcing ring 1230, and the orthographic projection of the supporting member 14 on the reinforcing ring 1230 is located within the orthographic projection of the supporting part 1241 on the reinforcing ring 1230. That is, the portion of the supporting part 1241 corresponding to the reinforcing ring 1230 overlaps with the fixing part 125, and the portion of the supporting part 1241 corresponding to the reinforcing ring 1230 overlaps with the supporting member 14. Thus, the pressure applied to the supporting member 14 can be transmitted to the supporting assembly 124 more evenly through the reinforcing ring 1230, reducing the influence of concentrated stress and enhancing the compressive strength of the supporting member 14.

[0095] It should be noted that the "overlap" mentioned in this embodiment does not refer to "complete overlap", but rather to the existence of a certain "overlapping area" between the fixing part 125 and the supporting part 1241, and between the supporting member 14 and the supporting part 1241.

[0096] Please combine Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 ;in, Figure 9 Provided for the embodiments of this utility model Figure 6 Enlarged view of point C in the middle; Figure 10 This is a schematic diagram of the cover plate 13 provided in an embodiment of the present utility model from a first perspective. Figure 11 This is a structural schematic diagram of the cover plate 13 provided in an embodiment of the present invention from a second perspective.

[0097] In one embodiment, the cover plate 13 includes a cover plate body 131, a plurality of limiting parts 132, and a protective part 133. The plurality of limiting parts 132 are fixed to the side of the cover plate body 131 near the bottom plate 121, and the plurality of limiting parts 132 are spaced apart along the length direction of the battery packaging box 1. The protective part 133 is fixed to the side of the cover plate body 131 away from the bottom plate 121. The protective part 133 includes a protective part body 1331 and a positioning part 1332. The protective part body 1331 is arranged around the edge of the cover plate 13, and the positioning part 1332 is formed by the protective part body 1331 and the positioning part 1332. The main body 1331 of the protective part extends towards the base plate 121, the positioning part 1332 covers at least part of the outer periphery of the box 11, and the positioning part 1332 and the limiting part 132 are spaced apart; wherein, a second slot 130 is provided between the positioning part 1332 and the limiting part 132, the second side 1112 is embedded in the second slot 130, and the second side 1112 abuts against the cover plate main body 131, thereby realizing the insertion and cooperation between the cover plate 13 and the box 11, thereby improving the assembly accuracy and stability of the side plate 111.

[0098] It is understood that by setting the second side 1112 to be embedded in the second slot 130, the side plate 111 is limited in the width and length directions of the battery packaging box 1, thereby improving the accuracy and stability of the connection between the cover plate 13 and the box body 11 during installation. At the same time, the slot cooperation between the second side 1112 and the cover plate 13 makes the installation and disassembly of the side plate 111 more convenient, and effectively avoids the risk of loosening that may be caused by screw or nail connection, further reducing assembly costs.

[0099] Furthermore, the plurality of limiting parts 132 are spaced apart along the length direction of the battery packaging box 1, thereby effectively fixing the relative position between the cover plate 13 and the bottom plate 121 and preventing the cover plate 13 from shifting or loosening due to external forces during use; at the same time, the protective part body 1331 is arranged around the edge of the cover plate 13, and the positioning part 1332 extends from the protective part body 1331 toward the bottom plate 121, and the positioning part 1332 covers at least part of the outer periphery of the box body 11, thereby improving the impact resistance of the box body 11.

[0100] Meanwhile, the positioning part 1332 can effectively replace the cushioning effect of paper corner protectors under external impact and pressure in related designs, avoiding the risk of deformation or detachment of paper corner protectors during transportation. Specifically, since the positioning part 1332 extends from the main body 1331 of the protective part towards the bottom plate 121, and the positioning part 1332 covers at least part of the outer periphery of the box 11, the positioning part 1332 can play a cushioning and protective role during transportation, reducing the risk of damage to the box 11 caused by external impact, thereby reducing the use of paper corner protectors and reducing material consumption and waste generation.

[0101] Specifically, the protective part 133 can be a steel strip structure, which has high strength and rigidity, and can effectively prevent external impacts from damaging the battery packaging box 1. The width of the protective part 133 is greater than or equal to 20 mm and less than or equal to 25 mm, so that the protective part 133 can fully cover and protect the edge of the cover plate body 131, enhancing its overall pressure resistance. At the same time, the thickness of the protective part 133 is greater than or equal to 1 mm and less than or equal to 2 mm, thereby avoiding an increase in the weight of the cover plate 13 due to excessive thickness of the protective part 133, thus maintaining the portability of the battery packaging box 1.

[0102] Please continue to combine Figures 1 to 11 In one embodiment, the battery packaging box 1 further includes a first buffer part 151 and a second buffer part 152. The first buffer part 151 is disposed between the limiting part 132 and the battery 2 to be transferred, and the second buffer part 152 is disposed between the bottom plate 121 and the battery 2 to be transferred. Through the cooperation of the first buffer part 151 and the second buffer part 152, the sealing performance of the box 11 is improved.

[0103] Specifically, the first buffer part 151 and the second buffer part 152 can both be made of pearl cotton material. Pearl cotton has good elasticity and cushioning effect. When subjected to external impact or vibration, pearl cotton can effectively absorb the impact force and reduce the relative movement between the box 11 and the battery to be transferred 2, thereby improving the shock resistance of the battery packaging box 1.

[0104] The height of the first buffer part 151 and the height of the second buffer part 152 are both greater than or equal to 15 mm and less than or equal to 20 mm. When the cover plate 13 is installed, due to the gravity of the cover plate 13 itself, the limiting part 132, the first buffer part 151, the battery to be transferred 2, the second buffer part 152 and the bottom plate 121 abut against each other, so that the first buffer part 151 and the second buffer part 152 generate a compression of 4 mm to 5 mm, thereby forming a sealed area in the box 11, ensuring that the environment inside the battery packaging box 1 is not disturbed by external air, dust, moisture and other factors, thereby enhancing the fixation and sealing between the cover plate 13 and the bottom plate 121.

[0105] Furthermore, the side of the support member 14 away from the base plate 121 abuts against the limiting part 132. The limiting part 132 can be a wooden strip structure. The wooden strip structure has high strength and rigidity, which can evenly distribute the pressure from the outside and reduce the situation of excessive local stress, thereby improving the compressive strength and stability of the cover plate 13. At the same time, the wooden strip structure has low weight and high environmental friendliness. Compared with other heavy materials, the wooden strip structure can reduce transportation and production costs.

[0106] After the cover plate 13 is installed, it can be further reinforced by using packing straps on the outside of the box 11 to ensure a stable connection between the cover plate 13 and the pallet 12, preventing the cover plate 13 and / or the pallet 12 from loosening or shifting during the transportation of the battery packaging box 1, thereby enhancing the safety and stability of the battery packaging box 1.

[0107] The embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
