[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. In addition, it should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the orientation words such as "upper" and "lower" generally refer to the upper and lower positions of the device in the actual use or working state, and specifically refer to the direction of the drawing in the drawings. And "inner" and "outer" refer to the outline of the device.

[0025] With the increasing design of the volume and weight of the energy storage battery pack, the strength of the traditional wooden box packaging structure may not be able to effectively support the heavy pressure of the multi-layer wooden box folding structure. In the multi-layer stacked wooden box packaging structure, the wooden box packaging structure located in the lower layer bears a large pressure, especially during transportation, vibration, collision or uneven pressure condition will further increase the risk of damage to the wooden box packaging structure, making the wooden box packaging structure located in the lower layer more prone to deformation or damage, thereby greatly reducing the protection of the energy storage battery pack located in the wooden box packaging structure.

[0026] In the traditional wooden box packaging structure, the fixing belt is usually arranged around the outside of the battery pack and the tray support plate. Although this design can fix the battery pack to the tray support plate, it also has some potential structural problems. Specifically, due to the arrangement of the fixing belt, the fixing belt will form a certain protrusion at the edge of the support plate. The existence of this protrusion will cause the inside of the side plate of the box cover to interfere with the edge of the support plate, resulting in the part of the side plate of the box cover that interferes with the protrusion protruding outward, i.e., the side plate of the box cover cannot completely fit the edge of the support plate. When the multi-layer wooden box packaging structure is stacked, the wooden box packaging structure at the bottom layer will bear a large pressure. Since the side plate of the box cover in the wooden box packaging structure cannot completely fit the edge of the support plate, the stress distribution of the side plate will be uneven, thereby greatly reducing the load-bearing strength of the box cover and easily causing the wooden box packaging structure to deform or be damaged.

[0027] To solve the above problems, the embodiment of the present application provides a packaging structure 100 for packaging a battery pack, please refer to Figures 1 to 4 , Figure 1 is a structural schematic diagram of the packaging structure 100 provided by the embodiment of the present application, Figure 2 is a structural schematic diagram of the packaging structure 100 from another perspective provided by the embodiment of the present application, Figure 3 is an exploded view of Figure 1 , Figure 4 is a structural schematic diagram of the tray 120 in Figure 3 . The packaging structure 100 includes a box cover 110, a tray 120, and at least one first fixing belt 130. The tray 120 includes a support plate 121, and the box cover 110 is located above the support plate 121. The box cover 110 is connected with the support plate 121 to enclose a containing space for containing the battery pack. The first fixing belt 130 fixes the battery pack to the tray 120. Each first fixing belt 130 includes a first part 131, which extends from the inside of the box cover 110 to the outside of the box cover 110. The edge of the support plate 121 is provided with at least one groove 140. Each groove 140 is used to accommodate the first part 131 of the corresponding first fixing belt 130.

[0028] In this embodiment, at least one groove 140 is designed at the edge of the support plate 121. When fixing the battery pack, the first fixing belt 130 passes through the corresponding groove 140, and the groove 140 can accommodate the first fixing belt 130. Therefore, when installing the box cover 110, the first fixing belt 130 will not interfere with the side plate 190 of the box cover 110, so that the side plate 190 of the box cover 110 can completely fit the edge of the support plate 121. When the multi-layer packaging structure 100 is stacked, the stress distribution of the side plate 190 of each packaging structure 100 is more uniform, so that the box cover 110 can evenly share the pressure from the upper packaging structure 100, thereby improving the load-bearing capacity of the packaging structure 100.

[0029] Through this optimized design, even if the packaging structure 100 encounters external factors such as vibration during transportation, the connection between the box cover 110 and the support plate 121 can still be stable and reliable, and the wooden box packaging structure 100 is not easy to deform or be damaged. Especially when the multi-layer packaging structure 100 is stacked, this structural design can effectively prevent the lower wooden box from deforming due to the weight concentration of the upper wooden box, further enhancing the stability of the multi-layer packaging structure 100.

[0030] In some embodiments, referring to Figures 3 to 5 , Figure 5 is Figure 4 a side view of the tray 120, the support plate 121 includes a plurality of side edges, at least one side edge is provided with two grooves 140, and the distance d of the two grooves 140 in the extension direction of the side edge where they are located and the size L of the side edge in the extension direction satisfy the following relationship: 0.3L≤d≤0.5L.

[0031] If the distance d is too close, the first fixing band 130 may not be able to fully play its fixing role, resulting in that the battery pack is not firmly fixed on the support plate 121, and is easy to shift or loosen, thereby affecting the safety and stability of the battery pack. On the contrary, if the distance d is too far, the fixing force of the first fixing band 130 may be relatively dispersed, thereby weakening the fixing effect on the battery pack. In order to ensure the stability of the battery pack fixed to the support plate 121, in this embodiment, the distance d of the two grooves 140 provided on the same side edge in the extension direction of the side edge where they are located is designed to be in the above parameter range, so that the distance between the two grooves 140 provided on the same side edge can fully adapt to the fixing needs of the first fixing band 130, while ensuring that the fixing band can uniformly exert pressure on the battery pack to firmly fix the battery pack to the support plate 121, thereby avoiding the problem that the fixing effect between the two grooves 140 provided on the same side edge is not ideal due to the distance being too close or too far.

[0032] Preferably, the support plate 121 is designed to include four sides, and each side is provided with two grooves 140. The first fixing band 130 passes through the corresponding two oppositely arranged grooves 140 to fix the battery pack to the support plate 121. It is easy to understand that the number of first fixing bands 130 directly affects the fixing effect of the battery pack. Generally, increasing the number of first fixing bands 130 can improve the fixing stability of the battery pack. However, the increase in the number of fixing bands, although it can improve the fixing effect of the battery pack, will also bring certain negative effects, such as the reduction of assembly efficiency and the increase of material cost. Therefore, in the preferred embodiment, four first fixing bands 130 are arranged on two groups of opposite sides, which can effectively meet the fixing needs of the battery pack, ensure the stability of the battery pack fixed to the support plate 121, and at the same time, ensure high assembly efficiency and reduce additional material cost.

[0033] In some embodiments, referring to Figure 5 , the two grooves 140 are symmetrically distributed along the central axis of the side, and the extension direction of the central axis is perpendicular to the extension direction of the side.

[0034] In the present embodiment, the two grooves 140 located on the side of the support plate 121 are designed to be symmetrically distributed along the central axis of the side. The structure design provided in the present embodiment has the following advantages:

[0035] On the one hand, when the first fixing band 130 is used to fix the battery pack to the support plate 121, the two grooves 140 located on the same side are designed to be symmetrically distributed, which can ensure that the fixing force applied by the first fixing band 130 is uniformly applied to the battery pack, thereby avoiding the problem of unstable fixation of the battery pack caused by uneven fixing force applied by the first fixing band 130. Through this symmetrical structure design, the battery pack can maintain a relatively stable fixed state, thereby ensuring the reliability of the battery pack during use. At the same time, it can also improve the structural strength of the support plate 121 itself. Since the grooves 140 are designed to be symmetrically distributed, when the support plate 121 is subjected to pressure, it can more evenly disperse stress, thereby reducing the risk of deformation or damage of the support plate 121 caused by excessive local stress.

[0036] On the other hand, during the batch production of the support plate 121, the two grooves 140 located on the same side are designed to be symmetrically distributed along the central axis of the side, so that the position of each groove 140 is relatively fixed and standardized. This standardized design facilitates the use of a pre-set production mold to produce the support plate 121, thereby improving the production efficiency and consistency of the product to some extent. During batch production, the consistency of the product can reduce the risk of scrap caused by design or processing errors of the support plate 121.

[0037] In some embodiments, referring toFigure 4 The shape of the groove 140 is designed to be U-shaped. Specifically, the side wall of the groove 140 includes a first side wall close to the edge of the support plate 121 and a second side wall away from the edge of the support plate 121, and the first side wall is between the edge of the support plate 121 and the second side wall, and the first side wall is perpendicular to the edge of the groove 140, and the second side wall is arc-shaped. In this embodiment, the shape of the groove 140 is designed to be U-shaped, which has the following advantages:

[0038] First, there is a large gap between the two opposite first side walls of the groove side wall, which is designed to provide a larger space to facilitate the clamping of the first fixing belt 130 inside the groove 140. Since the second side wall of the groove 140 is arc-shaped, when the first fixing belt 130 is tightened and fixed to the battery pack, the fixing belt will deform to some extent in the second side wall of the groove 140, so as to concentrate the fixing force of the fixing belt at the bottom of the second side wall of the groove 140, which can reduce the risk of displacement of the first fixing belt 130 to some extent, thereby enhancing the stability of the first fixing belt 130.

[0039] Secondly, the structure of the U-shaped groove 140 is relatively simple and easy to mass produce by mold. Compared with other more complex groove 140 designs, the U-shaped structure design can reduce the error in the manufacturing process to ensure the consistency of each groove 140.

[0040] In addition, the wrapping property of the U-shaped groove 140 makes it difficult for the packing belt to slip out of the slot or fall off, thereby ensuring the safety of the battery pack during transportation and use. Compared with a simple slot design, the U-shaped slot has a higher anti-falling effect when fixing the packing belt, which can prevent the first fixing belt 130 from loosening under vibration or external force, thereby ensuring that the battery pack is stably and reliably fixed to the support plate 121.

[0041] In some embodiments, referring to Figure 3 The first fixing belt 130 passes through the corresponding groove 140 in sequence and surrounds the outside of the battery pack and the support plate 121 to stably fix the battery pack to the support plate 121. Specifically, the first fixing belt 130 is in close contact with the outside of the battery pack and the support plate 121, and by applying a certain fixing force, the battery pack is stably fixed on the support plate 121. The first fixing belt 130 is in close contact with the surface of the battery pack, which can effectively distribute the fixing force evenly on the surface of the battery pack, thereby preventing local excessive pressure from causing the battery pack to deform or be damaged. The material and width of the first fixing belt 130 are not limited here, as long as it can withstand a large tensile force during fixing without being easily stretched or damaged. In addition, the groove 140 can limit the first fixing belt 130, which can effectively prevent the first fixing belt 130 from shifting or loosening, thereby ensuring the stability of the battery pack.

[0042] In some embodiments, referring to Figure 1 , Figure 2 , the packaging structure 100 further comprises a second fixing band 150, which encircles the outer side of the box cover 110 and the support plate 121, and is used to fix the box cover 110 and the tray 120. In the present embodiment, the second fixing band 150 can reduce the gap between the box cover 110 and the support plate 121 to a certain extent by exerting a certain fixing force on the box cover 110 and the support plate 121, so as to tightly fit the box cover 110 to the support plate 121. When the multi-layer packaging structure 100 is stacked, the second fixing band 150 can enhance the bending resistance of the box cover 110, so as to improve the structural strength of the box cover 110.

[0043] In some embodiments, referring to Figure 4 , the support plate 121 comprises a plurality of side edges, including a long side edge with a relatively long size and a short side edge with a relatively short size, and the tray 120 further comprises a plurality of first support members 160, two second support members 170, and at least one bottom plate 180. The bottom plate 180 is arranged opposite to the support plate 121, and the bottom plate 180 and the box cover 110 are located at different sides of the support plate 121, respectively. The first support members 160 and the second support members 170 are arranged in the extension direction of the long side edge of the support plate 121, and are connected between the support plate 121 and the corresponding bottom plate 180.

[0044] In order to enhance the support capability of the tray 120, in the present embodiment, the first support members 160, the second support members 170, and the bottom plate 180 are arranged on the side of the support plate 121 away from the box cover 110. The first support members 160 and the second support members 170 can effectively disperse the pressure exerted on the support plate 121, and prevent the local area from deforming or being damaged due to excessive load to a certain extent, so as to ensure the stability of the entire packaging structure 100. In particular, in the application scenario of the multi-layer packaging structure 100 being stacked, the packaging structure 100 located at the lower side can be prevented from being damaged.

[0045] In order to further optimize the support effect of the tray 120, in the present embodiment, the first support members 160 and the second support members 170 are arranged in the extension direction of the long side edge of the support plate 121. This arrangement can ensure that the support points between the first support members 160, the second support members 170, and the support plate 121 are uniformly distributed in the overall length direction of the support plate 121, thereby avoiding the situation of excessive stress in some areas. By arranging the first support members 160 and the second support members 170 along the long side edge of the support plate 121, the pressure exerted by the support plate 121 on the first support members 160 and the second support members 170 can be effectively dispersed, and the risk of damage to the first support members 160 and the second support members 170 due to excessive local pressure can be reduced.

[0046] Further, the uniform distribution of the first support members 160 helps to make the stress on each first support member 160 more uniform, thereby improving the stability of the first support members 160 and avoiding structural damage caused by excessive stress on some first support members 160, thereby improving the compression resistance of the tray 120 when stacked in the multi-layer packaging structure 100.

[0047] In some embodiments, referring to Figure 4 each second support member 170 is located between two adjacent first support members 160, including the end first support members 160 located at the outermost ends of the plurality of first support members 160, wherein each second support member 170 is located close to the end first support members 160 among the two adjacent first support members 160.

[0048] It is easy to understand that when the multi-layer packaging structure 100 is stacked, the first support members 160 close to the edges of the support plate 121 usually bear a large pressure and are therefore prone to deformation or damage. Therefore, in order to improve the overall load capacity of the tray 120, in the present embodiment, the second support members 170 are arranged close to the end first support members 160, so that the second support members 170 can share a part of the pressure from the support plate 121 with the end first support members 160, thereby reducing the stress intensity of the end first support members 160 and effectively reducing the risk of damage to the end first support members 160, especially when a large pressure is applied, which can avoid deformation or fracture of the end first support members 160 due to excessive local stress, thereby ensuring the stability and reliability of the tray 120 in the scenario of stacking the multi-layer packaging structure 100.

[0049] In addition, the two adjacent first support members 160 also include the middle first support members 160 connected to the middle part of the support plate 121, and the second support members 170 and the middle first support members 160 are designed with sufficient spacing, which not only ensures the uniform stress between the first support members 160 and the second support members 170, but also provides sufficient space for the tooling equipment to clamp the packaging structure 100.

[0050] Referring to Figure 6 , Figure 6 is Figure 1FIG. 13 is a schematic view of the internal structure of the box cover 110 of the packaging structure 100, the box cover 110 comprising a plurality of side plates 190 connected in sequence, and in some embodiments, the inner side of each side plate 190 is provided with a plurality of reinforcing members 200 to improve the structural strength of the box cover 110. Specifically, the reinforcing members 200 are in the shape of long strips and are uniformly distributed on the inner side of each side plate 190, which can effectively disperse the pressure on the top of the box cover to the surface of the entire box cover 110, avoiding excessive stress on the local area and reducing the risk of deformation and breakage of the side plates 190. In addition, the reinforcing members 200 can absorb and disperse the impact force to a certain extent when the box cover 110 is impacted, reducing the risk of damage to the side plates 190 and maintaining the integrity of the box cover 110.

[0051] In some embodiments, referring to FIG. 13, Figure 6 the packaging structure 100 further comprises a plurality of buckles 210, each buckle 210 being used to fix two adjacent side plates 190, one end of each buckle 210 being connected to a corresponding side plate 190, and the other end of the buckle 210 being connected to another side plate 190 to improve the structural strength of the box cover 110.

[0052] Specifically, when the multi-layer packaging structure 100 is stacked, the four corners of the box cover 110 usually bear a large pressure, and in order to enhance the pressure resistance of this position, the buckle 210 is arranged between two adjacent side plates 190 in the present embodiment, one end of the buckle 210 being connected to a side plate 190 and the other end being connected to an adjacent side plate 190, thereby forming a stable connection and making the structure of the box cover 110 more compact, thereby improving the overall pressure resistance of the box cover 110.

[0053] The utility model provides a kind of packaging structure 100. Among them, packaging structure 100 includes box cover 110, tray 120 and at least a first fixed band 130, tray 120 includes support plate 121, box cover 110 is located the top of support plate 121, box cover 110 is connected with support plate 121 to enclose a containing space for accommodating battery pack. First fixed band 130 fixes battery pack in tray 120, every first fixed band 130 includes first part 131, and first part 131 extends from the inside of box cover 110 to the outside of box cover 110. The edge of support plate 121 is equipped with at least one groove 140, and every groove 140 is used to accommodate corresponding first part 131. When fixing battery pack, first fixed band 130 passes through corresponding groove 140, and groove 140 can accommodate first fixed band 130. Therefore when installing box cover 110, first fixed band 130 cannot cause interference to the side plate 190 of box cover 110, so that the side plate 190 of box cover 110 can be completely attached to the edge of support plate 121, when multiple packaging structures 100 are stacked, the stress distribution of the side plate 190 of every packaging structure 100 is more uniform, so that box cover 110 can evenly share the pressure from upper packaging structure 100, thereby improve the carrying capacity of packaging structure 100.
