[0038] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0039] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0041] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0042] Square aluminum shell batteries have the characteristics of small size, easy assembly, fast charging, high discharge rate, etc., and are widely used in electric vehicles, energy storage and other fields. Through multi-layer stacking, its efficient electrochemical performance and high safety performance can meet the needs of electric vehicles for batteries, while realizing large-capacity, high-voltage battery packs, and can also be used for the storage of new energy such as solar energy or wind energy, so that these new energy sources can be more fully utilized.

[0043] The square aluminum shell battery includes an aluminum shell square shell and a lithium-ion battery cell arranged inside. The lithium-ion battery cell may include multiple lithium-ion batteries. The interior of the aluminum shell square shell is a hollow structure, and multiple lithium-ion batteries are accommodated in the aluminum shell square shell. After the preparation process of each lithium-ion battery cell is completed, it is necessary to use a transport packaging material to fully wrap the lithium-ion battery cell before shipment. Generally, a top patch will be attached to the top of the lithium-ion battery cell. On the one hand, it can play an insulating role to prevent the battery cell from short-circuiting with the external circuit. On the other hand, it can play a protective role to prevent the battery cell shell from being worn and scratched.

[0044] The transport packaging material generally includes a box body and a cover body. The lithium-ion battery cell is placed vertically in the box body along its own height direction, and then the top surface of the battery cell is covered by the cover body to complete the packaging. When opening, in order to facilitate operation and save effort, the operator generally lifts the cover body from one end and then takes away the entire cover body. However, when one end of the cover body is lifted and tilted, there is a risk of interference with the edge of the top patch, which may cause the cover body to scratch or damage the top patch during the unpacking process, resulting in failure of the insulation of the top patch, and then causing safety risks to the battery cell.

[0045] Based on this, see Figure 1The present application provides a transport packaging material structure 100 for transporting a battery cell 200. It can be understood that the battery cell 200 has a top surface 210, a bottom surface 220, and a peripheral side wall 230 connected between the top surface 210 and the bottom surface 220. The direction from the top surface 210 to the bottom surface 220 is the height direction H of the battery cell 200.

[0046] Specifically, see Figures 1 to 4 The transport packaging material structure 100 includes a box body 10 and a cover body 20. The box body 10 has an opening 25. The cover body 20 covers the opening 25 of the box body 10 and is surrounded by the box body 10 to form a receiving cavity 30 for receiving the battery cell 200. The receiving cavity 30 is inclined relative to the covering direction M of the box body 10, wherein the cover body 20 has a rotating end 23 and an opening end 24 that are plugged into the box body 10. The opening end 24 can rotate around the rotating end 23 and move away from the box body 10 to open at least part of the opening 25, and the opening end 24 avoids the top surface 210 of the battery cell 200 during the movement.

[0047] Specifically, before the cover 20 is closed on the box body 10, the opening 25 of the box body 10 is opened. At this time, the battery cell 200 can enter the box body 10 in a direction parallel to its own height direction H and the inclination direction of the accommodating cavity 30 and partially extend out of the box body 10. Then, by inserting the rotating end 23 and the opening end 24 into the box body 10, the cover 20 is closed. The cover 20 and the box body 10 completely wrap the top surface 210, the bottom surface 220 and the surrounding side wall 230 of the battery cell 200. It can be understood that at this time, part of the battery cell 200 enters the interior of the box body 10 and part is located inside the cover 20. The part of the battery cell 200 located inside the cover 20 includes the top surface 210 of the battery cell 200.

[0048] When it is necessary to open the cover 20 to take out the battery cell 200, the operator applies a force from one end of the rotating end 23 to make the opening end 24 rotate around the rotating end 23 to move from the inside of the box body 10 to the outside of the box body 10, thereby opening at least part of the opening 25. This opening method is more labor-saving and convenient to operate than directly removing the cover 20 in the direction opposite to the closing direction M of the cover 20.

[0049] Moreover, during the movement of the opening end 24, it avoids the top surface 210 of the battery cell 200, so that the top patch of the top surface 210 of the battery cell 200 is completely clear during the rotation and opening of the cover body 20. After the rotating end 23 moves to the opening portion 25 outside the box body 10, the operator can remove the cover body 20 as a whole by tilting it from the side of the opening end 24 outside the box body 10, and then the battery cell 200 can be seen, thereby removing the battery cell 200.

[0050] In this way, the present application changes the assembly orientation of the battery cell 200 in the transport packaging material structure 100 to form it in an inclined assembly form, and forms a movement trajectory of the open end 24 of the cover 20 and a complete avoidance of the top surface 210 of the battery cell 200, so that the cover 20 can be rotated relative to the box body 10 to open the opening 25 of the box body 10, which is convenient for the user to remove the cover 20 and take out the battery cell 200 in the next step, thereby ensuring the integrity of the top patch on the top of the battery cell 200.

[0051] It can be understood that the box body 10 and the cover body 20 are detachably connected through the rotating end 23 and the opening end 24 of the cover body 20. When the cover body 20 is covered on the box body 10, the cover body 20 is close to the box body 10 in a direction perpendicular to the surface where the opening 25 is located to complete the assembly with the box body 10. Figure 4 When the cover 20 needs to be removed, the operator applies a force along the closing direction M of the box body 10 to the rotating end 23 of the box body 10, so that the rotating end 23 forms a rotating axis, driving the opening end 24 to rotate to leave the opening 25 of the opening part of the box body 10. The operator can extend his hand through the opening 25 to remove the cover 20, and then remove the battery cell 200.

[0052] Specifically, see Figure 3 and Figure 5 The box body 10 has a first half cavity 31 and an opening 25 connected to the first half cavity 31, and the cover body 20 has a second half cavity 32. The box body 10 covers the opening 25 of the box body 10 so that the first half cavity 31 and the second half cavity 32 are spliced ​​to form a receiving cavity 30. When the battery cell 200 is placed in the receiving cavity 30, first, a part of the battery cell 200 is passed through the opening 25 into the second half cavity 32. At this time, the other part of the battery cell 200 (including the top surface 210 of the battery cell 200) is located outside the box body 10, that is, it extends out of the first half cavity 31 through the opening 25. The cover body 20 is closed to cover the part of the battery cell 200 located outside the box body 10. At this time, the top surface 210 of the battery cell 200 is located on the side close to the open end 24 in the horizontal direction N.

[0053] It can be understood that the top surface 210 of the battery cell 200 is inclined relative to the plane where the opening 25 is located, and the outer edge of the top surface 210 of the battery cell 200 is the position of the battery cell 200 closest to the open end 24. In the process of the rotating end 23 driving the open end 24 to rotate, the open end 24 bypasses the outer periphery of the top surface 210 of the battery cell 200 without contacting any position of the top surface 210 of the battery cell 200, thereby achieving the avoidance of the open end 24 and the top surface 210 of the battery cell 200.

[0054] From a geometric point of view, see Figure 3 The rotating end 23 has a rotating axis O, and the open end 24 has a minimum rotating radius R connected to the rotating axis O. minThe top surface 210 of the battery cell 200 has a maximum distance L from the line connecting the rotation axis O. max , R min Greater than L max , so that when the opening end 24 rotates to open the opening 25 , no position of the opening end 24 will come into contact with the top surface 210 of the battery cell 200 , ensuring that the opening end 24 and the top surface 210 of the battery cell 200 are completely avoided.

[0055] In one embodiment, see Figure 2 and Figure 6 The battery cell 200 and the box body 10 define a first plug-in slot 33 and a second plug-in slot 34, which are arranged on opposite sides of the box body 10 along the horizontal direction N. The rotating end 23 is inserted into the first plug-in slot 33 and is configured to be able to rotate in the first plug-in slot 33 under a force state. The opening end 24 is spaced apart from the battery cell 200 in the horizontal direction N, and can be driven by the rotating end 23 to rotate to disengage from the second plug-in slot 34. The horizontal direction N is perpendicular to the closing direction M of the cover body 20.

[0056] When the battery cell 200 partially enters the first half cavity 31, it does not occupy the entire space of the first half cavity 31, but occupies part of the first half cavity 31 in the box body 10, and defines the first plug-in slot 33 and the second plug-in slot 34 with the box body 10. It can be understood that the first half cavity 31 includes the first plug-in slot 33, the second plug-in slot 34, and the space for accommodating the battery cell 200. Then, the rotating end 23 of the cover body 20 is inserted into the first plug-in slot 33, and at the same time, the opening end 24 of the cover body 20 is inserted into the second plug-in slot 34, completing the assembly of the battery cell 200 in the transport packaging material structure 100.

[0057] It can be understood that after the rotating end 23 is inserted into the first plug-in slot 33, it can generate a set angle of rotation in the first plug-in slot 33 under the pressure of the closing direction M of the cover body 20. Similarly, after the opening end 24 is inserted into the second plug-in slot 34, it is spaced apart from the top surface 210 of the battery cell 200 to form a safety distance between the battery cell 200 and the opening end 24, ensuring that when the rotating end 23 rotates to drive the opening end 24 to disengage from the second plug-in slot 34, the opening end 24 can smoothly disengage from the second plug-in slot 34 and does not contact the top surface 210 of the battery cell 200.

[0058] Specifically, in some embodiments, see Figure 1 and Figure 3The box body 10 has a first supporting surface 11 and a second supporting surface 12 facing the accommodating cavity 30, the first supporting surface 11 is used to support the bottom surface 220 of the battery cell 200, the second supporting surface 12 is used to support part of the peripheral side wall 230 of the battery cell 200, and the second supporting surface 12 forms a first angle a with the horizontal direction N, and the first angle a is an acute angle, so that the battery cell 200 is placed at an angle, the bottom surface 220 of the battery cell 200 extends into the box body 10, and the top surface 210 of the battery cell 200 extends into the cover body 20, and a part of the peripheral side wall 230 located between the top surface 210 and the bottom surface 220 is in contact with the second supporting surface 12, forming a support for the peripheral side wall 230 by the second supporting surface 12.

[0059] In a specific embodiment, the first angle a satisfies greater than or equal to 40° and less than or equal to 60°, that is, the angle between the height direction H of the battery cell 200 and the horizontal direction N satisfies greater than or equal to 40° and less than or equal to 60°, and a can be 40°, 45°, 50°, 55°, 60°, etc., so that the battery cell 200 is tilted at an angle a. At the same time, referring to Figure 1 , the minimum distance L1 between the open end 24 and the battery cell 200 in the horizontal direction N satisfies greater than or equal to 4 mm and less than or equal to 5 mm, that is, the safety distance between the open end 24 and the battery cell 200 is set to L1, and L1 can be 4 mm, 4.2 mm, 4.4 mm, 4.6 mm, 4.8 mm, 5.0 mm, etc., so that the battery cell 200 maintains a suitable distance from the open end 24 on the basis of being tilted at an angle a, so that the open end 24 can avoid the top surface 210 of the battery cell 200 during the rotation process.

[0060] Specifically, see Figure 1 and Figure 6 The peripheral side wall 230 of the battery cell 200 includes a first portion 230a and a second portion 230b extending along its own height direction H, the second portion 230b is connected to the top surface 210 of the battery cell 200, the first portion 230a is connected to the bottom surface 220 of the battery cell 200 and is in contact with the second support surface 12, the second portion 230b is extended relative to the second support surface 12, and a second plug-in slot 34 is formed between the second portion 230b and the box body 10, the open end 24 is inserted into the second plug-in slot 34 and is spaced apart from the second portion 230b, so that at the connection portion between the top surface 210 of the battery cell 200 and the second portion 230b (i.e., the outer edge of the top surface 210 of the battery cell 200), a minimum distance L1 between the open end 24 and the battery cell 200 in the horizontal direction N is formed.

[0061] Specifically, the distance L2 of the second part 230b in the height direction H of the battery cell 200 satisfies greater than or equal to 50mm and less than or equal to 100mm. At this time, at least part of the peripheral side wall 230 of the battery cell 200 also extends into the cover body 20. L2 can be 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, etc.

[0062] In one embodiment, see Figure 1 and Figure 5 The cover body 20 has a first limiting surface 21 and a second limiting surface 22 facing the second half cavity 32. The first limiting surface 21 and the second limiting surface 22 are perpendicular, that is, the second angle b formed between the first limiting surface 21 and the second limiting surface 22 is 90°. The first limiting surface 21 is limitedly matched with a part of the peripheral side wall 230 of the battery cell 200, and the second limiting surface 22 is limited with the top surface 210 of the battery cell 200.

[0063] Specifically, see Figure 1 and Figure 6 The battery cell 200 includes a pole 240, which is arranged on the top surface 210 of the battery cell 200 and protrudes relative to the top surface 210. The second limiting surface 22 cooperates with the pole 240 to limit the battery cell 200. The first supporting surface 11, the second supporting surface 12, the first limiting surface 21 and the second limiting surface 22 fix the battery cell 200 from four sides, and the second limiting surface 22 and the first supporting surface 11 respectively limit the top surface 210 and the bottom surface 220 of the battery cell 200 along the inclined direction of the accommodating cavity 30. The pole 240 fits with the second limiting surface 22 to provide a limiting effect to prevent the top patch on the top surface 210 from directly contacting the second limiting surface 22.

[0064] Furthermore, the peripheral side wall 230 of the battery cell 200 that cooperates with the first limiting surface 21 defines a first plug-in slot 33 with the cover body 20, and the rotating end 23 is inserted into the first plug-in slot 33 and can rotate in the first plug-in slot 33 when subjected to force. In one embodiment, the cross-section of the rotating end 23 can be trapezoidal, and the upper bottom of the trapezoid faces the box body 10. At this time, a gap is formed between one side of the upper bottom and the peripheral side wall 230. When the rotating end 23 is subjected to force, one side of the upper bottom rotates toward the gap, thereby realizing the rotation of the rotating end 23 in the first plug-in slot 33.

[0065] In some embodiments, the cross-section of the second plug-in slot 34 formed by the second part 230b and the box body 10 may be trapezoidal in shape, and an opening is formed on one side of the upper bottom of the trapezoid, which forms a part of the opening 25. The open end 24 may be a columnar protrusion structure, and the open end 24 is arranged on the side of the second limiting surface 22 away from the first limiting surface 21 in the horizontal direction N, and is protruded relative to the second limiting surface 22 along the closing direction M of the cover body 20, so that when the second limiting surface 22 is limitedly engaged with the peripheral side wall 230 of the battery cell 200, the protruding open end 24 can enter the second plug-in slot 34 from the opening of the second plug-in slot 34.

[0066] For the convenience of explanation, a specific transport packaging material structure 100 is provided below, and the assembly and removal process of the battery cell 200 is as follows:

[0067] When assembling battery cell 200:

[0068] First, the bottom surface 220 of the battery cell 200 is placed on the first support surface 11, and the first portion 230a of the peripheral side wall 230 is placed on the second support surface 12. At this time, the second portion 230b of the peripheral side wall 230 extends relative to the second support surface 12 and forms a second insertion groove 34 with the box body 10, and the portion of the peripheral side wall 230 facing the opening 25 forms a first insertion groove 33 with the box body 10;

[0069] Then, the cover 20 is assembled to the opening 25 in a direction perpendicular to the opening 25, and the rotating end 23 is inserted into the first insertion groove 33, and the opening end 24 is inserted into the second insertion groove 34, and the assembly is completed. At this time, the height direction H of the battery cell 200 is inclined relative to the closing direction M of the cover 20, and the opening end 24 and the top surface 210 of the battery cell 200 are spaced apart in the horizontal direction N;

[0070] When you need to remove the battery cell 200:

[0071] First, a force is applied to the rotating end 23 along the closing direction M of the cover body 20. The rotating end 23 rotates in the first plug-in slot 33 and drives the opening end 24 to rotate until it gradually disengages from the second plug-in slot 34. In the process of moving from the second plug-in slot 34, the opening end 24 avoids the top surface 210 of the battery cell 200, thereby opening the opening of the second plug-in slot 34. Then the operator can easily lift up the cover body 20, thereby removing the battery cell 200 after taking off the cover body 20 as a whole.

[0072] In one embodiment, see Figure 7The transport packaging material structure 100 of the present application can form multiple layers, that is, a box body 10 and a cover body 20 form a layer of transport packaging material structure 100, and multiple layers of transport packaging material structures 100 are stacked at the same time to transport multiple battery cells 200. Specifically, taking the first-layer transport packaging material structure 100 as an example, the first-layer transport packaging material structure 100 is provided with a box body 10, and the cover body 20 matched with the box body 10 of the first layer is integrally arranged with the box body 10 of the second-layer transport packaging material structure 100. When the cover body 20 of the first layer is covered on the box body 10, the box body 10 of the second layer has also been assembled. Similarly, the third layer, the fourth layer and other upper layers are assembled until the top layer, and the cover body 20 of the top-layer transport packaging material structure 100 is covered alone.

[0073] In this way, the transport packaging material structure 100 provided in the present application, through reasonable angle settings and size settings, can achieve complete avoidance of the battery cell 200 during the process of opening the cover 20, avoiding damage to the top patch on the top surface 210 of the battery cell 200, thereby ensuring the safety performance of the battery cell 200.

[0074] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
