[0021] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0022] like Figures 1-4 As shown, the battery module unloading hoist of this utility model embodiment includes: a hoisting rod 1, a hoisting ring assembly 2, and a clamping assembly 3.

[0023] The lifting ring assembly 2 is connected to the lifting rod 1, and the lifting ring assembly 2 extends along the extension direction of the lifting rod 1 (e.g., ...). Figure 1 The lifting ring assembly 2 is movable in the left and right direction and is used to connect to the lifting mechanism. The clamping assembly 3 includes a clamping body 31 and a hook component 32. The clamping body 31 is connected to the lifting rod 1 and is movable along the extension direction of the lifting rod 1. The hook component 32 is connected to the clamping body 31 and is rotatable about a first axis orthogonal to the extension direction of the lifting rod 1. There are two clamping assemblies 3, which are arranged opposite to each other on both sides of the lifting ring assembly 2 in the extension direction of the lifting rod 1.

[0024] Specifically, such as Figures 1-4 As shown, the boom 1 is arranged in the left-right direction and serves as the foundation of the entire lifting device, facilitating the installation of other components. The lifting ring assembly 2 includes a lifting ring base 21 and a lifting ring body 22. The lifting ring base 21 and the boom 1 can be connected by a threaded connection (such as fixing the lifting ring base 21 and the boom 1 with a set screw), allowing the lifting ring base 21 to move in the left-right direction. The lifting ring body 22 is rotatably connected to the lifting ring base 21 to facilitate adaptation to the crane.

[0025] The clamping body 31 is connected to the lifting rod 1 via a threaded connection (such as fixing the lifting ring base 21 to the lifting rod 1 with a set screw), providing support for the clamping part. Two clamping assemblies 3 are symmetrically arranged on the left and right sides of the lifting ring assembly 2, and each clamping assembly 3 is movable along the extension direction of the lifting rod 1 to adapt to different models of battery modules.

[0026] It is understood that the hook component 32 is rotatable about the first axis to facilitate the assembly of the battery module. That is, when hoisting the battery module, the two hook components 32 can be arranged radially to facilitate the movement of the battery module to the corresponding position of the hook component 32; during hoisting, the hook component 32 is rotated to hook the battery module to the hoisting position, the crane is started, and under the gravity of the battery module, the cooperation between the hook component 32 and the battery module is more stable.

[0027] In other words, the mobility of the battery module unloading lifting ring assembly 2 and the clamping body 31 in this embodiment of the invention allows it to adapt to battery modules of different specifications and different working environments. The rotation function of the hook component 32 improves the clamping flexibility, making it convenient to clamp battery modules of different sizes and angles. It provides stable support for the handling of battery modules, reduces the risk of falling during handling, and also avoids the risk of contamination to the cells and current-carrying plates.

[0028] In some embodiments, the hook component 32 includes a hook body 321 and an auxiliary hook 33. The first end of the hook body 321 is provided with a hook 36, which extends toward one side of the lifting ring assembly 2. The first end of the auxiliary hook 33 is connected to the clamping body 31, and the second end of the auxiliary hook 33 is used to abut against the second end of the hook body 321. The second end of the hook body 321 is movable in the gap between the clamping body 31 and the auxiliary hook 33.

[0029] Specifically, such as Figures 1-4 As shown, the lower end of the hook body 321 is provided with a hook 36, and the hooks 36 in both clamping assemblies 3 face the center of the lifting device. The battery module is located between the two hooks 36 during lifting. The upper end of the hook body 36 can cooperate with the auxiliary hook 33.

[0030] It is understandable that, such as Figures 1-4As shown, the auxiliary hook 33 extends toward the body of the hook 36. The end of the auxiliary hook 33 is provided with an auxiliary hook. When the battery module is engaged with the hook 36, the upper end of the hook body 321 can be hooked by the auxiliary hook, thereby fixing and restricting the position of the hook body 321 and preventing the hook body 321 from detaching from the battery module during the hoisting process.

[0031] In other words, when the battery module needs to be clamped, the second end of the hook body 321 moves within the gap between the clamping body 31 and the auxiliary hook 33. The second end of the auxiliary hook 33 abuts against the second end of the hook body 321, limiting its range of movement and ensuring moderate clamping force. The hook 36 faces the lifting ring assembly 2, allowing the hook body 321 to stably clamp the battery module when the entire lifting device is lifted. The movement of the second end of the hook body 321 within the gap allows for adjustment of the clamping position according to the size and shape of the battery module. The supporting function of the auxiliary hook 33 enhances the stability of the clamping, preventing the battery module from shaking or falling during transport.

[0032] In some embodiments, the hook component 32 further includes an elastic element 34, the first end of which is connected to the clamping body 31, and the second end of which is connected to the second end of the hook body 321. The hook body 321 abuts against the auxiliary hook 33, and the elastic element 34 is in a stretched state.

[0033] It is understandable that, such as Figures 1-4 As shown, the elastic element 34 provides elastic force to assist the clamping action of the hook 33 body 321, enhancing the stability and adaptability of the clamping. The first end of the elastic element 34 is connected to the clamping body 31, and the second end of the elastic element 34 is connected to the second end of the hook body 321. When the hook body 321 abuts against the auxiliary hook 33, the elastic element 34 is in a stretched state, providing a continuous clamping force.

[0034] In other words, when the battery module needs to be clamped, the second end of the hook body 321 moves within the gap between the clamping body 31 and the auxiliary hook 33. The second end of the auxiliary hook 33 abuts against the second end of the hook body 321, limiting its range of movement and ensuring appropriate clamping force. The hook 36 faces the lifting ring assembly 2, and when the entire lifting device is lifted, the hook body 321 can stably clamp the battery module.

[0035] During clamping, the elastic element 34 is in a stretched state, providing continuous clamping force and enhancing clamping stability. The elastic properties of the elastic element 34 allow the hook body 321 to move within a certain range, adapting to battery modules of different sizes and shapes. The cushioning effect of the elastic element 34 can absorb vibrations and impacts generated during handling, reducing the impact force on the battery module and improving safety.

[0036] Preferably, there are multiple elastic elements 34, which are arranged at intervals along the first axial direction. It is understood that the multiple elastic elements 34 can cooperate between the auxiliary hook 33 and the hook body 321 to provide multiple supports. The design of multiple elastic elements 34 provides a more uniform clamping force, further enhancing the stability of clamping.

[0037] It should be noted that the elastic element 34 can be a spring, or other materials with elastic properties, such as rubber or metal sheet.

[0038] In some embodiments, the hook body 321 includes a hook segment 3211, a connecting segment 3212, and a limiting segment 3213 connected in sequence. The connecting segment 3212 is connected to the clamping body 31 via a rotating shaft. The axial direction of the rotating shaft coincides with the first axial direction. The hook 36 is disposed on the hook segment 3211. In a plane orthogonal to the axial direction of the rotating shaft, the hook segment 3211 and the limiting segment 3213 are spaced apart.

[0039] Specifically, such as Figures 1-4 As shown, the hook section 3211 is directly used to clamp the battery module, providing clamping force. The connecting section 3212 connects the hook section 3211 and the limiting section 3213, and is also connected to the clamping body 31 via a pivot. The limiting section 3213 limits the range of movement of the hook section 3211 to prevent excessive movement or loosening.

[0040] Understandably, when it is necessary to clamp the battery module, the hook segment 3211 rotates around the pivot via the connecting segment 3212 to adjust to a suitable angle. The gap between the hook segment 3211 and the limiting segment 3213 allows the hook segment 3211 to move within a certain range to accommodate battery modules of different sizes and shapes. With the hook 36 facing the lifting ring assembly 2, the hook segment 3211 can stably clamp the battery module when the entire lifting device is lifted.

[0041] In other words, the gap between the hook segment 3211 and the limiting segment 3213 allows the hook segment 3211 to move within a certain range, adapting to battery modules of different sizes and shapes. The design of the limiting segment 3213 ensures that the range of movement of the hook segment 3211 is within a safe range, improving the stability of clamping.

[0042] Preferably, there are multiple hooks 36, which are arranged at intervals along the axial direction of the rotating shaft. It is understood that arranging multiple hooks 36 at intervals along the axial direction of the rotating shaft allows for simultaneous clamping of different parts of the battery module, providing a more uniform clamping force. The interval between the hook section 3211 and the limiting section 3213 allows the hook section 3211 to move within a certain range, accommodating battery modules of different sizes and shapes.

[0043] In some embodiments, the clamping assembly 3 further includes an elbow clamp assembly 35, which includes a fixing member 351, a connecting rod 352, an elbow clamp wrench 353, and a limiting pin 354. The fixing member 351 is disposed on the clamping body 31, the elbow clamp wrench 353 is rotatably connected to the fixing member 351, the first end of the connecting rod 352 is rotatably connected to the elbow clamp wrench 353, and the first end of the limiting pin 354 is connected to the connecting rod 352. The elbow clamp assembly 35 has a first state and a second state. In the first state, the second end of the limiting pin 354 abuts against the lifting rod 1; in the second state, the second end of the limiting pin 354 is spaced apart from the lifting rod 1.

[0044] Specifically, such as Figures 1-4 As shown, the fixing member 351 is U-shaped. The lower end of the fixing member 351 can be connected to the clamping body 31 by screws or the like. The upper end of the connecting rod 352 passes through the fixing member 351 and is hinged to the elbow clamp wrench 353. The upper end of the limiting pin 354 is connected to the connecting rod 352 through the connecting plate 356. When the elbow clamp wrench 353 rotates, the connecting rod 352 can move in the up and down direction relative to the fixing member 351 so that the limiting pin 354 can move closer to or away from the lifting rod 1.

[0045] Understandably, in the first state, the limiting pin 354 abuts against the lifting rod 1, providing stable support and reducing the shaking of the battery module during clamping. In the second state, the limiting pin 354 is spaced apart from the lifting rod 1, allowing the elbow clamp assembly 35 to move within a certain range, further enhancing the adaptability of clamping and enabling the clamping assembly 3 to adapt to battery modules of different sizes and shapes, meeting diverse needs.

[0046] In some embodiments, the elbow clamp assembly 35 further includes a limiting nut 355, which is threadedly connected to the second end of the connecting rod 352. In the length direction of the connecting rod 352, the limiting nut 355 is located between the elbow clamp wrench 353 and the clamping body 31.

[0047] It is understandable that, such as Figures 1-4 As shown, the lower end (i.e. the second end) of the limiting pin 354 passes through the clamping body 31 and is connected to the limiting part nut to prevent the limiting pin 354 from disengaging from the clamping body 31 during the vertical movement.

[0048] Preferably, there are two limiting nuts 355, both of which are connected to the limiting pin 354. The two limiting nuts 355 are located on the upper and lower sides of the clamping body 31, respectively. The distance between the limiting pin 354 and the lifting rod 1 can be adjusted by adjusting the distance of the limiting nuts 355 according to the distance between the limiting pin 354 and the lifting rod 1.

[0049] In some embodiments, there are multiple booms 1, and the multiple booms 1 are arranged at intervals along a first axial direction.

[0050] It is understandable that, such as Figures 1-4 As shown, multiple lifting rods 1 are arranged at intervals along the first axial direction, increasing the coverage and stability of the lifting device. The arrangement of multiple lifting rods 1 improves the stability of the clamping assembly 3 during lifting. That is, the design of multiple lifting rods 1 provides more stable support, reduces swaying during clamping, and improves safety.

[0051] In some embodiments, the outer peripheral wall of the boom 1 is provided with scale lines 11 along the extension direction of the boom 1.

[0052] It is understandable that, such as Figures 1-4 As shown, the operator can visually determine the installation position of the clamping component 3 through the scale line 11, ensuring its symmetry and balance. This reduces the time required to adjust the clamping component 3 and improves overall operating efficiency.

[0053] In other words, the operator determines the installation position of the clamping assembly 3 according to the scale line 11, ensuring that it is symmetrically distributed on both sides of the lifting rod 1. By adjusting the position of the clamping assembly 3, the overall balance of the lifting device is maintained, vibration and sway are reduced, so that the symmetrically installed clamping assemblies 3 can evenly distribute the clamping force and avoid imbalance caused by asymmetrical positions.
