[0039] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0040] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the present application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0041] It is to be understood that the terms "first", "second", and the like used herein are used to distinguish between similar objects, and are not necessarily used to describe a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of practical implementation in other than the order illustrated or other than the order described herein. Moreover, the terms "comprise", "comprising", "include", "including", and the like used herein are specifically intended to be interpreted as inclusive rather than exclusive. That is, these terms are used in their broadest context, and are intended to be inclusive of these items listed following the term, as well as other items not specifically recited.

[0042] In the process of assembling the battery box to the container, the step of manually translating the battery box to the mounting frame, although an indispensable part of the traditional assembly process, implies the dual challenges of inefficiency and safety risks. Especially for the energy storage system battery box using lithium titanate technology, its design precision is high, but the weight of a single unit is generally between 300 and 400 kilograms, and the volume is large, direct manual handling is not only a strenuous physical test, but also a bottleneck for quality control and production safety. Without the intervention of appropriate auxiliary equipment or tools, this process often leads to the following problems:

[0043] Carrying such heavy battery boxes requires workers to exert great physical effort, and frequent heavy load operations can easily lead to worker fatigue accumulation, increasing the risk of labor injury, while being inefficient, which seriously affects the production rhythm.

[0044] Due to the large volume of the battery box and the complex internal structure, including sensitive liquid cooling plates, it is difficult to ensure accurate alignment of the mounting frame during manual translation, and slight deviation can cause minor damage to the internal structure of the battery box, especially when the bottom of the battery box contacts the mounting frame, as the stress point is concentrated, it is easy to cause scratches or breakage of the bottom liquid cooling plate, thereby affecting the overall performance of the battery box.

[0045] During the battery box carrying process, the position is fine-tuned by using brute force or crowbar, which not only increases the physical burden of workers, but also may cause the extrusion deformation of the battery cell due to uneven stress, and even cause the liquid cooling plate to break, the cooling liquid to leak, cause irreversible damage to the battery performance, and even cause fire and more serious safety accidents.

[0046] In combination Figures 1 to 5 According to the specific embodiments of the present application, a battery box turnover structure is provided.

[0047] Specifically, as shown in Figure 1 , Figure 2 and Figure 3 A battery box turnover structure includes a bearing table 1, the bearing table 1 has a bearing table surface, the bearing table surface is used for bearing a battery box 5, a plurality of roller assemblies 2 are provided on the bearing table surface, the plurality of roller assemblies 2 are installed on the bearing table surface at intervals, and the axes of the rotating shafts of the roller assemblies 2 are arranged in parallel.

[0048] The technical scheme of the present application is applied, a plurality of roller assemblies 2 are provided on the bearing table surface, the plurality of roller assemblies 2 are installed on the bearing table surface at intervals, and the axes of the rotating shafts of the roller assemblies are arranged in parallel, which ensures that the battery box can rotate freely when bearing the weight of the battery box, reduces the shaking and friction of the battery box during movement, thereby reducing the risk of damage, so that the battery box can smoothly slide with low friction, and the problem of scratching or scraping leakage of the bottom liquid cooling plate of the battery box when the battery box is installed in the prior art is solved.

[0049] In the embodiment, the maximum contact area of the bearing table 1 is S, and the bottom surface area of the battery box 5 is W, wherein S≥2 / 3W. By ensuring that the contact area between the bearing table 1 and the bottom surface of the battery box 5 is at least two-thirds of the latter, the stability of the battery box during the carrying process can be significantly improved, and the appropriate contact range is ensured, which not only avoids the possibility of bruising caused by too small contact area, but also reduces unnecessary wear caused by too large area.

[0050] Further, the axes of the two adjacent rotating shafts are arranged at the same distance. It can be ensured that during the carrying and rotating of the battery box, the weight is evenly distributed on all rotating shafts, which can avoid structural deformation or damage caused by uneven load, and also helps to maintain the balance of the battery box.

[0051] In an exemplary embodiment, the plurality of roller mounting slots 12 are arranged in a first preset direction on the bearing platform 1, and the plurality of roller assemblies 2 are rotatably mounted in the plurality of roller mounting slots 12 with their rotation axes arranged in parallel. By arranging the plurality of roller mounting slots 12 on the bearing platform 1, the roller assemblies 2 can be evenly distributed under the battery box, ensuring that the weight of the battery box 5 is evenly distributed when moving, preventing deformation of the battery box or damage to the internal battery cells due to uneven stress, and improving the structural stability during transportation.

[0052] In another specific embodiment, the plurality of roller assemblies 2 are spaced apart and mounted at the bottom of the bearing platform, and the rotation axes of the roller assemblies are arranged in parallel. This increases the contact area between the bearing platform and the battery box, enhancing the stability and strength of the entire turnover structure, especially when transporting heavy battery boxes, providing more reliable support and reducing the risk of accidents.

[0053] In this embodiment, it also includes a fork sleeve assembly 3 mounted at one end of the bearing platform 1, and the fork sleeve assembly 3 is detachably connected with the forklift arm. By mounting the fork sleeve assembly 3 at one end of the bearing platform 1, it helps to improve the controllability of the transportation process, reduces the displacement or shaking of the battery box due to unstable connection, and further protects the internal structure of the battery box.

[0054] As shown in Figure 4 , the fork sleeve assembly 3 includes two sleeve components 31 and two connecting plates 32. The two sleeve components 31 are arranged at one end of the bearing platform 1, each sleeve component 31 has an assembly space 311 extending in a first preset direction, and the two connecting plates 32 are connected to one side of the two sleeve components 31 respectively, and the other side of the two connecting plates 32 is detachably connected to the top of the bearing platform 1.

[0055] The two sleeve components 31 are arranged at one end of the bearing platform 1, forming a stable support structure, and the forklift arm can be accurately inserted into the assembly space 311 extending in the first preset direction. This design ensures stable connection of the forklift arm during transportation, reducing the risk of shaking or falling of the battery box due to unstable connection during transportation. The two connecting plates 32 are connected to the two sleeve components 31 and the top of the bearing platform 1 respectively, enhancing the overall structural strength of the fork sleeve assembly 3 and providing additional stable support. At the same time, the detachable connection of the connecting plate with the top of the bearing platform 1 makes the replacement and adjustment of the fork sleeve assembly 3 on different models of battery boxes or forklift arms simple, enhancing the versatility and maintenance convenience of the turnover structure.

[0056] Further, the distance between the two sleeve components 31 is L, and the width of the battery box is D, where 3 / 4D≥L≥1 / 3D. Designing L between 1 / 3D and 3 / 4D ensures that the sleeve assembly 3 can adapt to battery boxes of different widths while providing sufficient support width. This design allows the battery box to remain stable during handling, preventing tilting due to too narrow a sleeve component distance or unstable support due to too wide a sleeve component distance. The weight of the battery box can be more evenly distributed on the two sleeve components 31, avoiding excessive local stress and reducing the risk of damage to the bottom structure of the battery box, especially sensitive components such as liquid cooling plates.

[0057] In an exemplary embodiment, the turnover structure further comprises a limiting pin 4, the carrying table 1 is provided with a positioning hole 11, the limiting pin 4 has a working position cooperating with the positioning hole 11 and the mounting hole 51 of the battery box 5 to lock the battery box 5, and the limiting pin 4 has an unlocking position separated from the positioning hole 11 and the mounting hole 51 at the same time.

[0058] The cooperation of the limiting pin 4 with the positioning hole 11 and the mounting hole 51 ensures the accurate alignment of the battery box 5 on the carrying table 1. This alignment mechanism is particularly important when handling multiple battery boxes, as it prevents the battery box from changing position due to shaking during transportation and reduces the adjustment work during installation. The working position of the limiting pin 4 is designed such that after being inserted into the positioning hole 11 and the mounting hole 51, the battery box 5 can be effectively locked on the carrying table 1. This locking mechanism provides additional safety during handling, preventing the battery box from slipping off the carrying table due to accidental shaking or improper operation, reducing the risk of handling. When the battery box 5 needs to be removed, the operator can quickly unlock it. This feature improves handling efficiency, especially in work environments where battery boxes need to be frequently handled and installed, significantly reducing operation time.

[0059] As shown in Figure 5 The limiting pin 4 comprises a limiting rod 41 and a limiting seat 42. When the limiting rod 41 is in the working position, at least part of the limiting rod 41 is located inside the mounting hole 51 and the positioning hole 11. The limiting seat 42 is connected to one end of the limiting rod 41, and the outer diameter of the limiting seat 42 is greater than the inner diameter of the mounting hole 51.

[0060] When the limiting rod 41 is in the working position, it at least partially penetrates into the mounting hole 51 and the positioning hole 11, forming a mechanical buckle that ensures the battery box 5 is firmly fixed on the carrying table 1 during handling, preventing accidental sliding or falling. This stability is particularly important for heavy load handling, significantly reducing the risk during handling.

[0061] Further, the limiting pin 4 comprises a hand-held portion 43, which is connected with the limiting seat 42, and the limiting seat 42 is located between the limiting rod 41 and the hand-held portion 43. The design of the hand-held portion 43 provides an easy-to-grasp part for the operator, making it more convenient to lock or unlock the limiting pin 4. The operator can easily control the movement of the limiting rod 41 through the hand-held portion 43 without directly contacting the limiting rod, which is particularly important when carrying heavy battery boxes, and can reduce the physical exertion and operation complexity of the operator.

[0062] In the present embodiment, the outer diameter of the limiting seat 42 is A, and the inner diameter of the mounting hole 51 is B, wherein A > B. The outer diameter A of the limiting seat 42 is greater than the inner diameter B of the mounting hole 51, which means that the limiting seat 42 cannot pass through the mounting hole 51 completely, thereby effectively preventing the limiting pin 4 from accidentally falling off from the mounting hole 51 when the limiting pin 4 is in the locked state. This design ensures the fixation of the battery box during transportation, reducing the risk of displacement or falling of the battery box due to the falling of the limiting pin.

[0063] Further, the outer diameter of the limiting rod 41 is C, and the inner diameter of the positioning hole 11 is F, wherein C ≥ B and C ≥ F. This makes the insertion and extraction process of the limiting rod 41 more smooth, and the operator can intuitively control the movement of the limiting rod 41 through the hand-held portion 43 without the need for additional tools or complex steps, simplifying the operation process and improving work efficiency. During the insertion or extraction process, there is a certain fit between the limiting rod 41 and the mounting hole 51, which can reduce the wear between them and prolong the service life of the limiting pin 4 and the battery box.

[0064] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in various different forms, and should not be construed as being limited to only the embodiments set forth herein. It should be understood that the embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art, and in the drawings, the thicknesses of layers and regions can be exaggerated for clarity, and the same reference numerals are used throughout the drawings to designate the same elements, and thus a description thereof will be omitted.
