Description

Technical Field

[0001] The utility model relates to the technical field of mechanical hoists, and in particular to a hoisting connection structure and device for a power battery pack based on CAE simulation optimization. Background Art

[0002] Power battery packs are mainly installed on new energy mining vehicles. These vehicles are mainly used in special industrial scenarios such as smart mines and mine shafts, and undertake functions such as employee transportation, inspections, emergency evacuation, and small material transportation. Affected by flammable and explosive environments such as underground gas, the battery pack, as the sole power source for the vehicle, has explosion-proof performance as the primary design indicator. Even if a thermal runaway explosion occurs inside the battery module, the outer shell structure must remain intact and leak-free. Therefore, battery packs generally adopt a thickened frame design, resulting in a single cell weight generally exceeding 1.5 tons. However, such heavy battery packs need to be transported through specific lifting structures in mobile scenarios such as testing, loading, replacement, and disassembly.

[0003] Currently, rectangular fixing blocks with threaded holes are welded to the four corners of the battery pack's top, along with M20 threaded lifting rings (which must be stored as separate accessories in the vehicle's tool box). During transportation, the onboard threaded lifting rings are screwed in one by one, and then hoisted through the ropes. Afterwards, the battery pack is removed and recycled. This structure is cumbersome to operate and presents significant risks:

[0004] First, each lifting ring must be installed and removed manually, which is cumbersome and carries the risk of loss. Second, the lifting rings are purchased externally, and products from different batches or suppliers vary in thread size consistency, body size, and material properties, which can easily lead to uneven lifting force. Third, it is difficult to ensure that the four lifting ring holes are oriented in the same direction during manual tightening, and angle deviations often occur, affecting the efficiency and quality of rope threading and lifting. Fourth, when the lifting ring is not tightened, it is easy for vibration to cause the thread to slip, causing the battery pack to fall. Overtightening may damage the thread and cause it to get stuck, delaying the operation. The above problems are particularly prominent in confined space operations, seriously restricting handling efficiency and work safety. Utility Model Content

[0005] The embodiment of the present utility model provides a lifting connection structure and device for a power battery pack based on CAE simulation optimization, so as to solve the technical problems in the prior art of mining new energy battery packs using detachable threaded lifting rings, which are complicated to operate, have inconsistent quality, are difficult to control angles, and have high lifting safety risks during transportation.

[0006] In view of the above technical problems, an embodiment of the present invention provides a lifting connection structure for a power battery pack based on CAE simulation optimization, comprising at least two lifting connectors symmetrical about the center of the mining power battery pack and installed on different side walls of the mining power battery pack, wherein the lifting connectors include a first connector, a second connector, and a rope groove hanging plate connected between the first connector and the second connector;

[0007] The first connecting member and the second connecting member are both fixedly connected to the side wall of the mining power battery pack, and a hoisting hole for the hoisting rope to pass through is naturally formed between the rope groove hanging plate and the side wall of the mining power battery pack.

[0008] Optionally, at least two of the hoisting connectors are installed in pairs on the same side wall of the mining power battery pack.

[0009] Optionally, the mining power battery pack is enclosed by an upper cabin plate, a lower cabin plate, a side cabin plate, an upper cover plate and a lower bottom plate; the top end of the side cabin plate is fixed to the bottom surface of the upper cabin plate and retracted inward from the outer edge of the upper cabin plate to form a concave storage groove between the outer side of the side cabin plate and the outer edge of the upper cabin plate for accommodating and installing the lifting connector.

[0010] Optionally, the first connecting member and the second connecting member are mirror-symmetrical with respect to the rope groove hanger plate;

[0011] The first connecting member includes a first fixing plate, a first side wing plate fixedly connected to the side end of the first fixing plate facing the rope groove hanging plate, and a first upper wing plate fixedly connected to the first fixing plate and adjacent to the first side wing plate;

[0012] The second connecting member includes a second fixing plate, a second side wing plate fixedly connected to the side end of the second fixing plate facing the rope groove hanger plate, and a second upper wing plate fixedly connected to the second fixing plate and adjacent to the second side wing plate.

[0013] Optionally, the first fixing plate and the second fixing plate are fixedly connected to the outer wall of the side deck, and the first upper wing plate and the second upper wing plate are fixedly connected to the bottom surface of the upper deck.

[0014] Optionally, the first side wing plate, the rope groove hanging plate, the second side wing plate and the outer wall of the side cabin plate form the hanging hole.

[0015] Optionally, an arc-shaped bent edge is provided on the end surface of the rope groove hanging plate away from the first upper wing plate; and the bending direction of the arc-shaped bent edge is away from the side cabin plate.

[0016] Optionally, reinforcing ribs are provided on the upper deck, the lower deck and the side deck.

[0017] Optionally, an inspection cover is detachably mounted on the upper deck.

[0018] The present utility model also provides a lifting and connecting device for a power battery pack based on CAE simulation optimization, comprising the above-mentioned lifting and connecting structure for a power battery pack based on CAE simulation optimization.

[0019] In the present invention, by providing a lifting connector, the steps of manually installing and removing the lifting ring are eliminated, and the lifting can be done immediately after installation. This not only simplifies the handling process, but also completely avoids the risk of losing the lifting ring. Since the lifting connector is directly fixedly connected to the mining power battery pack, it no longer relies on universal parts purchased from outside, thus ensuring the consistency of the size and material properties of the lifting connector, and ensuring the uniformity of the lifting force. The design of the lifting connector also ensures the consistency of the direction of the lifting point, avoiding the influence of angle deviation on the efficiency and quality of rope threading and lifting. At the same time, the fixed connection method of the lifting connector does not have the problem of thread slippage or jamming caused by not tightening or over-tightening, thereby greatly reducing the risk of the mining power battery pack falling and improving the safety of the operation. Especially in confined space operations, this improvement significantly improves the handling efficiency and safety, and provides a new solution for the transportation of mining power battery packs that saves time, effort, safety and reliability.

DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] In the description of the present invention, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like, indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description.

Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0032] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0033] like Figures 1 to 4 As shown, an embodiment of the present invention provides a lifting connection structure for a power battery pack based on CAE simulation optimization, comprising at least two lifting connectors 2 that are symmetrical about the center of a mining power battery pack 1 and mounted on different side walls of the mining power battery pack 1. The lifting connectors 2 include a first connector 21, a second connector 22, and a rope groove hanger plate 23 connected between the first connector 21 and the second connector 22. The first connector 21 and the second connector 22 are both fixedly connected to the side wall of the mining power battery pack 1, and a lifting hole 24 for the lifting rope to pass through is naturally formed between the rope groove hanger plate 23 and the side wall of the mining power battery pack 1. One of the lifting connectors 2 is provided on each of the two oppositely disposed side walls of the mining power battery pack 1, and multiple lifting connectors 2 can be provided on each side wall.

[0034] It can be understood that by symmetrically arranging at least two lifting connectors 2 on two opposite side walls of the mining power battery pack 1, stable lifting of the mining power battery pack 1 is achieved. Multiple lifting connectors 2 can be set on each side wall, further enhancing the balance and reliability of the lifting. This design not only simplifies the lifting operation and avoids the trouble of installing and disassembling traditional threaded lifting rings, but also ensures the safety and stability of the lifting process through the firm connection of the first connector 21 and the second connector 22 to the side wall of the mining power battery pack 1, and the lifting hole 24 formed by the rope groove hanging plate 23 and the side wall. At the same time, the symmetrically arranged lifting connectors 2 can evenly disperse the lifting force, reduce local stress concentration, effectively protect the structure of the mining power battery pack 1, extend its service life, and significantly improve the safety and convenience of the mining power battery pack 1 during the lifting process.

[0035] Understandably, by providing the lifting connector 2, the steps of manually installing and removing the lifting rings are eliminated, achieving the goal of putting on and lifting immediately. This not only simplifies the handling process but also completely avoids the risk of losing the lifting rings. Since the lifting connector 2 is directly fixedly connected to the mining power battery pack 1, it no longer relies on externally purchased general parts. Therefore, the consistency of the size and material properties of the lifting connector 2 is guaranteed, ensuring the uniformity of the lifting force. The design of the lifting connector 2 also ensures the consistency of the lifting point orientation, avoiding the impact of angle deviation on the efficiency and quality of rope threading and lifting. Specifically, if the commonly used detachable lifting rings are used, the lifting rings need to be manually fixed to the mining power battery pack 1 each time they are installed. Since this is a manual operation, it is difficult to ensure that the lifting rings are installed in exactly the same orientation each time, which may cause the circular holes of the four lifting rings to deviate in orientation. However, the lifting connector 2 is fixedly installed on the mining power battery pack 1. Its position and orientation are accurately determined during the manufacturing process, thus ensuring that the orientation of the lifting point is consistent each time it is lifted. During a lifting operation, if the orientation of the lifting points is inconsistent, the rope may not pass smoothly through all the lifting rings when threading, requiring repeated adjustments. This not only reduces lifting efficiency but also may cause uneven force due to angular deviation, affecting the safety and quality of the lifting. The design of the lifting connector 2 ensures the consistency of the lifting points, thus avoiding this angular deviation problem.

[0036] Furthermore, the fixed connection of the lifting connector 2 eliminates the risk of thread slippage or sticking due to under- or over-tightening, significantly reducing the risk of the mining power battery pack 1 falling and improving operational safety. This improvement significantly improves handling efficiency and safety, particularly in confined space operations, providing a new, time-saving, labor-saving, safe, and reliable solution for handling the mining power battery pack 1.

[0037] In one embodiment, if Figures 1 to 2 As shown, at least two of the aforementioned lifting connectors 2 are mounted in pairs on the same side wall of the mining power battery pack 1. The number of lifting connectors 2 can be adjusted as needed. The symmetrical layout of the multiple lifting connectors 2 forms a multi-hanging point structure. Combined with the lifting holes 24 enclosed by the rope groove hanger plate 23, this disperses the lifting force and avoids the risk of single-point overload. The lifting connectors 2 can be welded to the side wall of the mining power battery pack 1. This multi-hanging point layout shortens the rope threading path and, combined with the concealed design of the storage slot 5 (described later), reduces operational complexity in confined spaces.

[0038] In one embodiment, if Figures 1 to 2 、 Figure 6-Figure 7As shown, the mining power battery pack 1 is enclosed by an upper deck 11, a lower deck 12, side decks 13, an upper cover 14, and a lower base 15. The top end of the side deck 13 is fixed to the bottom surface of the upper deck 11 and is retracted inward from the outer edge of the upper deck 11 to form a concave receiving groove 5 between the outer side of the side deck 13 and the outer edge of the upper deck 11 for accommodating and installing the lifting connector 2. It can be understood that fixing the lifting connector 2 in the receiving groove 5 not only maintains the external dimensions of the mining power battery pack 1 unchanged, but also ensures the connection strength. The design of the receiving groove 5 ensures that the lifting connector 2 does not protrude from the outer surface of the mining power battery pack 1 when not in use, reducing the complexity and potential collision risks when operating in a narrow space, while also reducing the risk of damage to the lifting connector 2 itself. This design also helps to improve the appearance of the mining power battery pack 1. Since the lifting connector 2 is fixedly installed, it also reduces the time consumption and labor intensity caused by manual operation, thereby improving the handling efficiency.

[0039] In one embodiment, if Figures 3 and 4 As shown, the first connector 21 and the second connector 22 are mirror images of each other about the rope groove hanger plate 23. The first connector 21 includes a first fixing plate 211, a first side wing plate 212 fixedly connected to the end of the first fixing plate 211 facing the rope groove hanger plate 23, and a first upper wing plate 213 fixedly connected to the first fixing plate 211 and adjacent to the first side wing plate 212. The second connector 22 includes a second fixing plate 221, a second side wing plate 222 fixedly connected to the end of the second fixing plate 221 facing the rope groove hanger plate 23, and a second upper wing plate 223 fixedly connected to the second fixing plate 221 and adjacent to the second side wing plate 222. It can be understood that the first fixing plate 211 and the second fixing plate 221 are mirror images. This mirror image layout (i.e., the first fixing plate 211 and the second fixing plate 221 are symmetrical about the rope groove hanger plate 23) ensures that the lifting force is evenly transmitted through the rope groove hanger plate 23 to the lifting connectors 2 on both sides, avoiding stress concentration on one side. The structural design of the first fixing plate 211 , the first side wing plate 212 , the first upper wing plate 213 and the corresponding second connecting member 22 increases the contact area between the connecting member and the side wall of the mining power battery pack 1 , thereby enhancing the strength and rigidity of the connection.

[0040] In one embodiment, if Figure 1 、 Figure 3As shown, the first fixing plate 211 and the second fixing plate 221 are fixedly connected to the outer wall of the side deck 13, and the first upper wing plate 213 and the second upper wing plate 223 are fixedly connected to the bottom surface of the upper deck 11. It can be understood that by fixing the fixing plates and the upper wing plates to the side deck and the upper deck, respectively, a stable support structure is formed, which can effectively withstand and distribute the forces generated during lifting, reduce the risk of structural deformation, and increase the contact area with the main body of the mining power battery pack 1, thereby improving the strength of the connection.

[0041] In one embodiment, if Figure 2 、 Figures 3 and 4 As shown, the first side wing plate 212, the rope groove hanging plate 23, the second side wing plate 222 and the outer wall of the side compartment plate 13 form the hoisting hole 24. It can be understood that the design of the hoisting hole 24 allows a hoisting rope or chain to pass through safely and stably for hoisting the mining power battery pack 1.

[0042] In one embodiment, if Figures 3 and 4 As shown, the end surface of the rope groove plate 23 facing away from the first upper wing plate 213 is provided with an arcuate bent edge 25; the arcuate bent edge 25 is curved away from the side panel 13. As can be understood, the design of the arcuate bent edge 25 helps guide the lifting rope smoothly into the lifting hole 24, preventing the rope from getting stuck or deflecting during entry, ensuring a smooth lifting process. The arcuate bent edge 25 transforms point contact of the lifting rope into surface contact, dissipating local stress and preventing wear and tear of the rope due to stress concentration.

[0043] In one embodiment, if Figures 1 to 2 As shown, the upper deck 11, the lower deck 12, and the side deck 13 are all provided with reinforcing ribs 3. It can be understood that the reinforcing ribs 3 can effectively disperse and resist stress concentration that may occur during the lifting process, thereby reducing the risk of structural deformation and improving the durability and reliability of the battery pack.

[0044] In one embodiment, if Figures 1 to 2 As shown, an inspection cover 4 is detachably mounted on the upper deck 11. It is understandable that the inspection cover 4 is used to be opened to facilitate installation or inspection of parts in the mining power battery pack 1.

[0045] The present invention also provides a lifting and connecting device for a power battery pack based on CAE simulation optimization, including the above-mentioned lifting and connecting structure for a power battery pack based on CAE simulation optimization. In the device of the above-mentioned embodiment of the present invention, the lifting and connecting device for a power battery pack based on CAE simulation optimization includes at least two lifting connectors 2 that are symmetrical about the center of a mining power battery pack 1 and are installed on different side walls of the mining power battery pack 1, and the lifting connectors 2 include a first connector 21, a second connector 22, and a rope groove hanging plate 23 connected between the first connector 21 and the second connector 22; the first connector 21 and the second connector 22 are both fixedly connected to the side wall of the mining power battery pack 1, and a lifting hole 24 for the lifting rope to pass through is naturally formed between the rope groove hanging plate 23 and the side wall of the mining power battery pack 1.

[0046] In a specific embodiment, if Figure 5 As shown, the length of the first upper wing plate 213 and the second upper wing plate 223 can be set to 30-45 mm to ensure that the lifting rope can pass through smoothly. The length of the first fixing plate 211 and the second fixing plate 221 can be set to 75-105 mm, and the width of the first fixing plate 211 and the second fixing plate 221 can be set to 40-60 mm to ensure that the strength of the lifting connector 2 will not be deformed due to the pulling of the lifting rope. The length of the rope groove hanging plate 23 can be set to 30-45 mm to ensure that the lifting rope can pass through smoothly. In addition, an elliptical hole is opened on the first fixing plate 211 and the second fixing plate 221, and the radius of the elliptical part is set to 10-15 mm. The distance between the outer edge of the elliptical hole and the end edge of the first fixing plate 211 or the second fixing plate 221 is set to 10-15 mm. Welding can be performed along the outer edge of the elliptical hole to fix the first fixing plate 211 and the second fixing plate 221 to the side cabin plate 13. Understandably, the above setting is verified by CAE simulation analysis, combined with the structural strength of the lifting connector 2 itself and the weight of the lifting connector 2, in order to ensure that the bracket does not deform or fall off during the handling and lifting process, if the steel material with a yield strength ≥1000MPa is selected, the thickness of the lifting connector 2 can be selected between 2.5-3mm; if the steel material with a yield strength of <1000MPa and ≥650MPa is selected, the thickness of the lifting connector 2 can be selected between 3-4.5mm; steel with a yield strength of <650MPa is not recommended.
