Description

Technical Field

[0001] This disclosure claims the priority of a Chinese patent application filed with the Chinese Patent Office on December 28, 2023, with the application number 202323661942.8, and the entire content of the above application is incorporated herein by reference. This disclosure relates to the technical field of battery packs, specifically to the battery pack package structure.

Background Art

[0002] In the prior art, the transportation of new energy battery packs is often packaged for transportation using many wooden boxes. The structure of traditional wooden boxes includes the canopy and tray of the box body. Here, the outer short side plate of the canopy of the box body is extended, and the outer short side plate and the load block of the tray are fixed with wood screws, and the extended outer short side plate is located on the outer surface of the box body of the wooden box.

Summary of the Invention

Problems to be Solved by the Invention

[0003] However, with such an installation method, the surface of the wooden box is not flat, it is difficult to arrange during the process of the battery pack package, and it is also disadvantageous for the arrangement and stacking of batches of wooden boxes even after boxing. During the long-distance transportation process of battery packs, due to the unevenness of the road, the wooden box is prone to tipping over, causing collisions between the battery pack and the wooden box body or between the battery pack and the ground, which may lead to accidents such as battery liquid leakage, spontaneous combustion, and explosion.

Means for Solving the Problems

[0004] In a first aspect, the present disclosure provides a battery pack package structure. The battery pack package structure includes a tray structure and a lid. The tray structure includes a tray body and a support portion. The tray body includes a first side and a second side that is away from the first side in a first direction. The tray body extends along a plane where a second direction and a third direction are located. The first side of the tray body is configured to attach a battery pack. The support portion is fixedly connected to the second side of the tray body. At least a part of the support portion protrudes from the periphery of the tray body in the plane extension direction of the tray body. The support portion and the tray body together form a concave groove located at the periphery of the tray body. Any two of the first direction, the second direction, and the third direction intersect with each other. The lid is installed on the first side of the tray body. In the lid, a cavity is formed on the side facing the tray body. The battery pack is located on the first side of the tray body and is accommodated in the cavity. At least a part of the lid overlaps in the concave groove, and the tray body is accommodated in the cavity.

Advantages of the Invention

[0005] In an embodiment of the present disclosure, the battery pack is arranged on the first side of the tray body, and the lid is placed on the tray structure to complete the assembly of the battery pack and the battery pack package structure. Here, at least a part of the lid overlaps the tray structure, so that the positioning and attachment between the lid and the tray structure can be completed. Compared with the prior art where it is necessary to adjust the shape of the top cover of the box body to complete the assembly between the top cover of the box body and the tray, in the technical solution of the embodiment of the present disclosure, there is no need to change the shape of the lid. The positioning can be achieved by the concave groove formed by the combination of the tray body and the support portion when the lid and the tray structure are assembled. As a result, the entire surface of the lid and the tray structure becomes flat, which is advantageous for the arrangement, stacking, and transportation of multiple battery pack package structures.

Embodiments for Carrying Out the Invention

[0007] In the description of the present disclosure, unless otherwise clearly defined and limited, the terms "connected", "connected to", and "fixed" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, an integration, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, or a communication inside two elements or an interaction relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in the present disclosure according to the specific situation.

[0008] In the present disclosure, unless otherwise clearly defined and limited, the fact that the first feature is "above" or "below" the second feature may include that the first and second features are in direct contact, or may also include that the first and second features are not in direct contact and are in contact through another feature therebetween. Further, the fact that the first feature is "above", "above the upper side", or "upper surface" of the second feature includes that the first feature is directly above and obliquely above the second feature, and the horizontal height of the first feature is higher than that of the second feature. The fact that the first feature is "below", "below the lower side", or "lower surface" of the second feature includes that the first feature is directly below and obliquely below the second feature, and the horizontal height of the first feature is lower than that of the second feature.

[0009] In the description of this embodiment, the terms "upper", "lower", "left", "right", "front", "rear", etc., referring to orientation or positional relationship, are for the purpose of facilitating description and operation based on the orientation or positional relationship shown in the accompanying drawings, and do not indicate or imply that the shown device or element must have a specific orientation and be configured and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present disclosure. Also, the terms "first" and "second" are used for descriptive distinction and have no special meaning.

[0010] The present disclosure provides a battery pack package structure. FIGS. 1 to 9 are one embodiment of the present disclosure. In FIG. 2, the Z direction in the figure is taken as the first direction, the Y direction as the second direction, and the X direction as the third direction. Any two of the first direction, the second direction, and the third direction intersect each other, and the angle at which any two of the first direction, the second direction, and the third direction intersect each other may be 80°, 85°, 90°, 95°, or 100°. In the following embodiments, it is described that the angle between any two of the first direction, the second direction, and the third direction is 90°.

[0011] Referring to FIGS. 1 to 4, the battery pack package structure 100 includes a tray structure 1 and a lid 3. The tray structure 1 includes a tray body 11 and a support portion 12. The tray body 11 includes a first side 1A and a second side 1B that is away from the first side 1A in the first direction. The tray body 11 extends along the plane where the second direction and the third direction are located. The first side 1A of the tray body 11 is configured such that the battery pack 4 can be attached. The support portion 12 is fixedly connected to the second side 1B of the tray body 11. At least a part of the support portion 12 protrudes from the periphery of the tray body 11 in the plane extension direction of the tray body 11. The support portion 12 and the tray body 11 together form a concave groove 2 located at the periphery of the tray body 11. The lid 3 is installed on the first side 1A of the tray body 11. In the lid 3, a cavity 3A is formed on the side facing the tray body 11. The battery pack 4 is located on the first side 1A of the tray body 11 and is accommodated in the cavity 3A. At least a part of the lid 3 overlaps in the concave groove 2, and the tray body 11 is accommodated in the cavity 3A.

[0012] In an embodiment of the present disclosure, the battery pack 4 is disposed on the first side 1A of the tray body 11, and the cover body 3 is placed on the tray structure 1 to complete the assembly of the battery pack 4 and the battery pack package structure 100. Here, at least a part of the cover body 3 overlaps the tray structure 1, so that the position-limiting attachment between the cover body 3 and the tray structure 1 can be completed. Compared with the prior art where it is necessary to adjust the shape of the top cover of the box body to complete the assembly between the top cover of the box body and the tray, in the technical solution of the embodiment of the present disclosure, there is no need to change the shape of the cover body 3. During the assembly of the cover body 3 and the tray structure 1, the position can be limited by the concave groove 2 formed by the combination of the tray body 11 and the support portion 12. As a result, the entire surface of the cover body 3 and the tray structure 1 becomes flat, which is advantageous for the arrangement, stacking, and transportation of a plurality of battery pack package structures 100.

[0013] It can be understood that since the entire surface of the cover body 3 and the tray structure 1 is flat and the tray body 11 is accommodated in the cavity 3A, the overall aesthetic appearance of the battery pack package structure 100 can also be improved.

[0014] Referring to FIGS. 2, 3, and 9, since the formation of the concave groove 2 is automatically formed during the assembly of the tray body 11 and the support portion 12, there is no need to separately install the concave groove 2 after the assembly with the tray body 11 or the support portion 12, and the manufacturing process of the battery pack package structure 100 can be effectively reduced. Similarly, the fact that the concave groove 2 is formed in combination with the tray body 11 to form the concave groove 2 results in a higher structural strength of the concave groove 2 compared to the case where the concave groove 2 is formed in either one of the tray body 11 or the support portion 12. That is, when the concave groove 2 is formed in the tray body 11 or the support portion 12, a part of the structure of the tray body 11 or the support portion 12 is hollowed out, and thereby, while the concave groove 2 is formed, the structural strength of the tray body 11 or the support portion 12 decreases.

[0015] In an embodiment of the present disclosure, in order to be advantageous for stacking and transporting the battery pack package structure 100, both the lid 3 and the tray body 11 are installed in a rectangular shape. Compared with the lid 3 and the tray body 11 having other shapes, such as circular or irregular structures, such an installation can effectively improve the space utilization rate during the transportation of the battery pack package structure 100.

[0016] Referring to FIG. 2, the tray body 11 is installed so as to extend along a plane where the second direction Y and the third direction X are located, thereby forming a first side 1A facing the lid 3 and enabling the battery pack 4 to be attached. The periphery of the tray body 11 refers to opposite sides of the tray body 11 in the second direction Y and the third direction X. It may be understood that at least a part of the support portion 12 protruding from the periphery of the tray body 11 means that on the plane where the second direction Y and the third direction X are located, the area occupied by the support portion 12 is larger than the area occupied by the tray body 11, and the support portion 12 can also be directly observed when observing in the direction from the lid 3 to the tray structure 1 in the first direction Z.

[0017] Referring to FIGS. 2 and 5, in some embodiments of the present disclosure, the battery pack package structure 100 further includes a plurality of position limiting portions 5, and the plurality of position limiting portions 5 are fixed to the first side 1A of the tray body 11 and limit the position of the battery pack 4. That is, in this embodiment, when the battery pack 4 is disposed on the first side 1A, in order to prevent the battery pack 4 from moving in the extending direction of the tray body 11, a plurality of position limiting portions 5 are installed on the peripheral side of the battery pack 4 to limit the movement of the battery pack 4 in the second direction Y and the third direction X. Here, a plurality of position limiting portions 5 are installed on the tray body 11, and the plurality of position limiting portions 5 together with the tray body 11 form an attachment area for the battery pack 4. Here, the battery pack 4 is installed in a rectangular shape and has four side surfaces in the second direction Y and the third direction X, and thus two position limiting portions 5 are installed on each corresponding side surface of the battery pack 4, and the two position limiting portions 5 located on any one side surface of the battery pack 4 are installed at intervals.

[0018] In some embodiments of the present disclosure, the battery pack package structure 100 further includes a first buffer component 6 and at least one first packaging band 7. The first buffer component 6 is located on the side away from the tray body 11 in the first direction of the battery pack 4, and at least one first packaging band 7 is installed around the tray body 11 and the battery pack 4. The first buffer component 6 is located between the first packaging band 7 and the battery pack 4. That is, in this embodiment, by installing the first packaging band 7, the movement of the battery pack 4 in the first direction Z can be restricted. The first buffer component 6 is installed on the side of the battery pack 4 in the first direction Z, and can buffer and dampen the battery pack 4 in the first direction Z. At the same time, the first buffer component 6 covers the side where the battery pack 4 is away from the tray body 11 in the first direction Z, so that the first packaging band 7 located on this side does not directly contact the battery pack 4, and damage, breakage, or indentation of the battery pack 4 can be avoided. It can be understood that when the first packaging band 7 is in direct contact with the battery pack 4, since the contact area between the first packaging band 7 and the battery pack 4 is small, when the battery pack 4 receives a force in the first direction Z, scratches, breakage, or indentation are likely to occur on the painted surface of the contact area between the first packaging band 7 and the battery pack 4. In one embodiment of the present disclosure, four first packaging bands 7 are installed. Two first packaging bands 7 are taken as a set. The two sets of first packaging bands 7 surround the tray body 11 and the battery pack 4 in the second direction Y and the third direction X respectively. The two first packaging bands 7 in the same set are spaced apart from each other to ensure the reliability that the battery pack 4 and the tray body 11 are relatively fixed in the first direction Z.

[0019] By installing the first packaging band 7 and the position limiting part 5, the battery pack 4 can be simultaneously position-limited in the first direction Z, the second direction Y, and the third direction X. The first packaging band 7 is installed after the battery pack 4 is arranged, so as not to interfere with the assembly of the battery pack 4.

[0020] In some embodiments of the present disclosure, the battery pack package structure 100 further includes at least one protective component 8, the protective component 8 is installed on the periphery of the first buffer component 6, a part of the protective component 8 overlaps the first buffer component 6 and is located between the first buffer component 6 and the first packaging band 7, and another part of the protective component 8 extends along the first direction Z and is located between the battery pack 4 and the first packaging band 7. Here, since the first packaging band 7 needs to be installed around the battery pack 4 and the tray body 11, at least a part of the first packaging band 7 and the battery pack 4 come into contact with the sides in the second direction Y or the third direction X, which may cause scratches, damages, or dents on the painted surface of the battery pack 4. Therefore, the protective component 8 is installed to protect the sides of the battery pack 4 in the second direction Y or the third direction X. To enable the protective component 8 to be fixed between the first packaging band 7 and the battery pack 4, at least a part of the protective component 8 is located between the first buffer component 6 and the first packaging band 7, and the first packaging band 7 is fixed to the tray body 11 and the battery pack 4 to clamp the protective component 8. In one embodiment of the present disclosure, the protective component 8 is installed on a corner guard. Here, the periphery of the first buffer component 6 is installed protruding from the periphery of the battery pack 4, so that when the first packaging band 7 is tightened, the distance between the first packaging band 7 and the battery pack 4 becomes larger, and the situation of the first packaging band 7 damaging the painted surface of the battery pack 4 after tightening the battery pack 4 can be further avoided.

[0021] Referring to FIGS. 2 and 5, the battery pack package structure 100 further includes a second buffer component 9, and the second buffer component 9 is installed between the battery pack 4 and the tray body 11. By installing the second buffer component 9, buffering and shock absorption can be performed on the battery pack 4 in the first direction Z. The second buffer component 9 and the first buffer component 6 can perform buffering on both sides of the battery pack 4 in the first direction Z at the same time, thereby enhancing the buffering and shock absorption ability of the battery pack 4. Here, both the first buffer component 6 and the second buffer component 9 are installed on pearl cotton.

[0022] Referring to FIGS. 3 and 7, the support portion 12 includes a plurality of support blocks 12A that are connected to the tray body 11. The plurality of support blocks 12A are arranged in an array and at least a part of each support block 12A installed close to the periphery of the tray body 11 protrudes from the periphery of the tray body 11 in the plane extension direction of the tray body 11. Here, the support blocks 12A are used to support the tray body 11. Since the plurality of support blocks 12A are arranged in an array, that is, there is a gap between two adjacent support blocks 12A, it is convenient to insert the forks of a forklift to place and transfer the battery pack package structure 100. At least a part of each support block 12A installed close to the periphery of the tray body 11 protrudes from the periphery of the tray body 11, thereby forming the concave groove 2 located in the tray structure 1. In one embodiment of the present disclosure, nine support blocks 12A are installed and arranged in an array along the plane where the second direction Y and the third direction X are located.

[0023] In some embodiments of the present disclosure, the support portion 12 further includes at least one first plate component 12B. The first plate component 12B extends along the second direction Y or the third direction X. Each first plate component 12B is installed on the side away from the tray body 11 in the first direction Z of the plurality of support blocks 12A. Each first plate component 12B connects the plurality of support blocks 12A arranged along the second direction Y or the third direction X. That is, in this embodiment, by fixing the plurality of support blocks 12A with the first plate component 12B, it is possible to prevent the support blocks 12A from falling off during the process of unloading and loading of the forklift.

[0024] Referring to FIG. 4, the battery pack package structure 100 further includes a plurality of second plate components 10. The plurality of second plate components 10 are installed on the cavity wall of the cavity 3A. By installing the plurality of second plate components 10, the cover body 3 can be strengthened, thereby increasing the structural strength of the cover body 3. In addition, the plurality of second plate components 10 are installed on the cavity wall of the cavity 3A and are not exposed outside the cover body 3, thereby increasing the structural strength of the cover body 3 and at the same time making the appearance of the cover body 3 flat.

[0025] Referring to FIGS. 5, 6 and 8, the cover 3 includes a first sub - part 31 and a second sub - part 32 that are connected to each other. A plurality of second plate components 10 are connected to the first sub - part 31, and at least a part of the second sub - part 32 overlaps within the concave groove 2. That is, in this embodiment, since a part of the cover 3 overlaps within the concave groove 2, by installing the plurality of second plate components 10 on the first sub - part 31, it is possible to avoid the installation of the second plate components 10 interfering with the alignment between the cover 3 and the concave groove 2. In one embodiment of the present disclosure, the cover 3 includes two first side plates 14 that are relatively installed in the second direction Y and two second side plates 15 that are relatively installed in the third direction X. Five second plate components 10 are installed on each first side plate 14 or each second side plate 15. Four of the five second plate components 10 located on each first side plate 14 or each second side plate 15 form a rectangular frame structure, and the remaining one of the five second plate components 10 is located at the central position of the rectangular frame structure, thereby enhancing the structural strength of the first side plate 14 or the second side plate 15. For ease of understanding, in FIG. 8, the portion of area B surrounded by the frame is the first sub - part 31, and the portion of area C is the second sub - part 32.

[0026] Referring to FIG. 8, in some embodiments of the present disclosure, the mounting positions of some of the second plate components 10 located on the first sub - part 31 are installed closer to the second sub - part 32, thereby enhancing the local structural strength of the second sub - part 32 where the cover 3 is embedded in the concave groove 2. It can be understood that some of the second plate components 10 installed closer to the second sub - part 32 are installed in contact or not in contact with the tray body 11 in the first direction Z when the cover 3 and the tray structure 1 are assembled.

[0027] Referring to FIG. 1, the battery pack package structure 100 further includes at least one second packaging band 13, and the second packaging band 13 is installed around the tray body 11 and the lid 3. It can be understood that the movement restriction in the second direction Y and the third direction X can be realized between the lid 3 and the tray body 11 through the concave groove 2, and after the lid 3 and the tray body 11 are assembled, they can be fixed with wood screws. However, when a plurality of battery pack package structures 100 need to be stacked and packaged, in order to ensure the certainty of the fixation of the plurality of battery pack package structures 100, the second packaging band 13 is installed to restrain the lid 3 and the tray body 11. In one embodiment of the present disclosure, four second packaging bands 13 are installed. Two second packaging bands 13 are taken as a set. The two sets of second packaging bands 13 respectively surround the tray body 11 and the battery pack 4 in the second direction Y and the third direction X. The two second packaging bands 13 in the same set are spaced apart from each other, thereby ensuring the certainty of the fixation of the lid 3 in the first direction Z.

[0028] Note that the battery pack 4 is located between the lid 3 and the tray body 11, and is positionally restricted in the first direction Z, the second direction Y, and the third direction X by the first packaging band 7 and a plurality of position restricting parts 5. At the same time, the first buffer part 6 and the second buffer part 9 buffer and protect the battery pack 4, and the protection part 8 avoids damage to the battery pack 4. Therefore, the battery pack 4 can avoid scratches on the surface of the battery pack 4 during long-distance transportation. At the same time, the battery pack 4 can avoid situations such as liquid leakage, spontaneous combustion, and explosion caused by vibration due to road unevenness during long-distance transportation. A rapid separation form can be realized between the lid 3 and the tray structure 1 through the concave groove 2, which can reduce the packaging process of the battery pack package structure 100 and increase the production volume of the product.

[0029] The embodiments of the present disclosure further propose a method for assembling a battery pack, including the following steps S1 to S7. S1: Placing the first buffer part 6 on the first side 1A of the tray body 11. S2: Placing the battery pack 4 on the side away from the tray body 11 in the first direction Z of the second buffer part 9. S3: To arrange the first buffer component 6 on the side away from the tray body 11 in the first direction Z of the battery pack 4. S4: To arrange a plurality of protection components 8 on the side away from the battery pack 4 in the first direction Z of the first buffer component 6. S5: To arrange a plurality of position-limiting parts 5 on the peripheral sides in the second direction Y and the third direction X of the battery pack 4, and to fix the plurality of position-limiting parts 5 to the tray body 11. S6: To fix the battery pack 4 and the tray body 11 using the first packaging band 7. S7: To cover the tray body 11 with the lid 3 and fix the tray body 11 and the lid 3 with wood screws. It can be understood that in step S7, when it is necessary to transport a plurality of battery pack package structures 100, a second packaging band 13 needs to be further installed to fix the lid 3 and the tray body 11.
