[0035] Please refer to Figures 1 to 3 This application provides a module battery lifting device 10 and a module moving device 100 for lifting and moving a battery module 200. The module battery lifting device 10 includes a body 11 and a first connecting member 12. The body 11 has an adjustment through hole 111, and a plurality of adjustment positions 112 are provided in the adjustment through hole 111. One end of the first connecting member 12 is disposed in one of the adjustment positions 112, and the other end is connected to the battery module 200. In this way, by providing a plurality of adjustment positions 112 in the adjustment through hole 111, the first connecting member 12 can be adjusted according to battery modules 200 of different lengths, which can adapt to battery modules 200 of different lengths, has strong versatility, and the lifting device adjustment operation is simple, the switching time is short, and the production efficiency is high; in addition, the module battery lifting device 10 has a simple overall structure and is easy to operate.

[0036] In one feasible embodiment, the module battery hoist 10 further includes a second connector 13. A first end of the second connector 13 is connected to the body 11, and the other end is connected to the first connector 12. The first end of the second connector 13 is disposed on one of the adjustment positions 112. By providing the second connector 13, the connection between the hoist and the battery module 200 becomes more flexible, increasing the stability and reliability of the module battery hoist 10 during use.

[0037] In one feasible implementation (not shown in the figures), the module battery lifting device 10 may only include a first connector 12, which can be directly connected to the battery module 200 and the body 11 of the lifting device. For example, the first connector 12 may be a chain structure, with one end of the chain connected to the battery module 200 and the other end connected to the adjustment position 112. Specifically, the connection to the adjustment position 112 may be a snap-fit ​​connection.

[0038] In one feasible implementation, a plurality of limiting plates 113 are sequentially arranged within the adjusting through hole 111 along a first direction X. The limiting plates 113 are spaced apart from the adjusting position 112 along the first direction X. The adjusting through hole 111 has opposing bottom and top walls along a second direction Y. A first end of the limiting plate 113 along the second direction Y is fixedly connected to the bottom wall of the adjusting through hole 111, and a second end is at a first preset distance from the top wall of the adjusting through hole 111. This first preset distance is greater than the thickness of the second connecting member 13 in the adjusting position 112 portion along the second direction Y. The second direction Y is perpendicular to the first direction X. That is, the length of the limiting plate 113 along the second direction Y is less than the width of the adjusting through hole 111 along the second direction Y, and the second direction Y is perpendicular to the first direction X. The distance from the top of the limiting plate 113 along the second direction Y to the top of the adjusting through hole 111 should be greater than the length of the portion of the second connecting member 13 disposed within the adjusting position 112 along the second direction Y. In other words, if the top of the limiting plate 113 is a certain distance or space from the top of the adjustment through hole 111, the second connector can bypass the limiting plate 113 to adjust its position 112. This facilitates the movement of the second connector 13 between different adjustment positions 112. When adjusting the position according to different battery specifications, it is not necessary to disassemble the second connector 13; the second connector 130 only needs to slide above the limiting plate 113. Alternatively, the limiting plates 113 can be described as several protruding structures, with the adjustment position 112 formed between two adjacent protruding structures. The two outermost protrusions form the adjustment position 112 between the adjustment through hole 111. Alternatively, the adjustment through hole 111 can be described as having several grooves sequentially formed along the first direction X, with the grooves serving as the adjustment positions 112 and the protrusions between adjacent grooves serving as the limiting plates 113. In this way, the position of the first connector 12 or the second connector 13 can be limited in the first direction X, thereby enabling the hoisting of battery modules 200 of different lengths. In this system, a rectangular coordinate system is established with the length direction of the body 11 of the module battery hanger 10 as the X-axis, the height direction as the Y-axis, and the thickness direction as the Z-axis. Then, the first direction X is parallel to the X-axis, and the second direction Y is parallel to the Y-axis. Since the length of the limiting plate 113 along the second direction Y is less than the width of the adjusting through hole 111 along the second direction Y,

[0039] Furthermore, to ensure the stability of the second connecting member 13 in the adjustment position 112, the height of the limiting plate 113 protruding from the adjustment through hole 111 should be greater than the thickness of the second connecting member 13. In other words, the length of the limiting plate 113 in the second direction Y is greater than the length of the portion of the second connecting member 13 disposed within the adjustment position 112 in the second direction Y. This ensures that the second connecting member 13 will not shift or slip in the adjustment position 112, thus preventing loss of balance.

[0040] In one feasible implementation, the adjustment position 112 can also be the limiting plate 113 or include the limiting plate 113 and the aforementioned groove structure. That is, the second connecting member 13 can be disposed on the limiting plate 113 or disposed in the groove. In this way, the full length range adjustment can be realized within the entire adjustment through hole 111.

[0041] In one feasible implementation, the second connector 13 can be an annular structure. This annularity is not limited to a circular ring; it can also be an irregular circle, such as an ellipse, a D-shape, a gourd shape, or a teardrop shape. Such a non-circular structure allows the second connector 13 to be more reliably fixed within the adjustment position 112, improving the stability of the module battery lifting device 10 during installation. Furthermore, the second connector 13 can be a spring buckle. For example, an annular locking buckle; or, for example, an S-buckle structure. Such a spring buckle structure facilitates locking and unlocking connections, and facilitates the connection between the second connector 13 and the first connector 12.

[0042] In one feasible implementation, a plurality of the limiting plates 113 are arranged sequentially and evenly along a first direction X. The second connecting members 13 are arranged in pairs along the first direction X. The first connecting members 12 are arranged in pairs along the first direction X. One first connecting member 12 connects to one second connecting member 13. Thus, the evenly arranged limiting plates 113 and the symmetrically arranged first connecting members 12 and second connecting members 13 make the battery module 200 more stable in the width direction, ensure the symmetrical arrangement of the hooks 121 on both sides of the module, and result in uniform force distribution on the body 11.

[0043] In one feasible implementation, the body 11 has two adjustment through holes 111 arranged along the first direction X. The two adjustment through holes 111 are symmetrically opened about the central axis of the body 11, and the two second connecting members 13 are respectively connected to the adjustment positions 112 of the two adjustment through holes 111. In this way, the adjustment through holes 111 are divided into two symmetrical adjustment through holes 111, which facilitates symmetrical adjustment when adjusting the position of the first end of the second connecting member 13 for different specifications of battery modules 200. At the same time, the discontinuous design of the adjustment through holes 111 can increase the structural stability of the module battery hanger 10, so that the module battery hanger 10 can bear a larger weight, the force is evenly distributed, and the overall rigidity is improved.

[0044] In one possible implementation, each of the first connectors 12 includes at least one hook 121. For example... Figure 2 and Figure 3 As shown, each of the first connectors 12 includes two hooks 121. The battery module 200 has grooves corresponding to the hooks 121 on two sides along the first direction X. The end of the hook 121 engages with the groove, and its top end connects to the second connector 13, providing a force to the battery module 200 along the second direction Y. The second direction Y is perpendicular to the first direction X and parallel to the central axis of the body 11. The connection between the hooks 121 and the grooves facilitates the connection and separation of the first connectors 12 and the battery module 200, improving the efficiency of the hoisting process.

[0045] In one feasible implementation, the connection between the first connector 12 and the battery module 200 can also be made by means of a buckle or a lock to improve the reliability of the connection, which will not be elaborated here.

[0046] In one feasible implementation, the two second connectors 13 and the two first connectors 12 are symmetrically arranged about the central axis. This design avoids tilting or swaying caused by a shift in the center of gravity during hoisting. The symmetrical arrangement of the second connectors 13 and first connectors 12 can evenly distribute the weight of the battery module, reducing the load on one side of the connector, thereby reducing the risk of structural deformation and improving the safety of the hoisting process.

[0047] In one feasible implementation, the difference between the distance between the two adjustment positions 112 of the two second connectors 13 along the first direction X and the distance between the ends of the hooks 121 of the two first connectors 12 along the first direction X is within a second preset range. In this way, the hooks 121 can hook the battery module 200 upwards, ensuring the connection effect of the module battery hanger 10 and preventing the battery module 200 from slipping off the hooks 121.

[0048] In one feasible implementation, the second preset range is less than 5cm. This further ensures that the pulling force applied by the hook 121 to the battery module 200 is vertically upward. This upward hooking further ensures the connection effect of the module battery lifting device 10, prevents the battery module 200 from slipping off the hook 121, and improves the reliability of the lifting.

[0049] In one feasible implementation, the body 11 is provided with weight-reducing grooves 114. By providing weight-reducing grooves 114, the overall weight of the body 11 is reduced while maintaining its strength and preventing deformation. Further, the weight-reducing grooves 114 are two triangular structures symmetrically arranged along a plurality of first directions X. Thus, the weight-reducing holes are triangular, which not only reduces the overall weight of the body 11 but also maintains its strength and prevents deformation.

[0050] In one feasible implementation, the body 11 of the module battery hanger 10 is integrally formed. This integral forming of the body 11 eliminates weak points in the connection through an integrated manufacturing process, significantly improving structural strength and impact resistance, reducing assembly steps to lower production costs and increase efficiency; its seamless design extends service life, simplifies maintenance, and optimizes the balance between performance and weight; furthermore, its high material utilization and lightweight design reduce energy consumption, combining high strength, durability, and environmental advantages, making it particularly suitable for high-load, high-frequency, or customized industrial scenarios.

[0051] In one feasible implementation, the body 11 of the module battery hanger 10 can be made of a metal material, such as aluminum alloy or steel, to ensure sufficient strength and durability. The adjustment through-hole 111 can be machined into the body 11, and the adjustment position 112 can be formed by providing a step or protrusion structure within the adjustment through-hole 111. The limiting plate 113 can be an integrally formed structure with the body 11, or it can be a separate component installed later.

[0052] In one feasible embodiment, the hook 121 portion of the first connector 12 can be made of a bent metal rod with an anti-slip surface to increase friction with the groove of the battery module 200. The second connector 13 can be a chain or metal rod structure, with one end connected to the adjustment position 112 of the body 11 and the other end connected to the top of the first connector 12.

[0053] Accordingly, this application also provides a module moving device 100. The module moving device 100 includes a gantry frame 30, a lifting hook 20, and the aforementioned module battery hoist 10. A hoisting hole 115 is provided on the side of the module battery hoist 10 away from the adjustment through hole 111 along its central axis. The lifting hook 20 is mounted on the gantry frame 30 and connected to the module battery hoist 10 through the hoisting hole 115. The gantry frame 30 can drive the lifting hook 20 to move the module battery hoist 10.

[0054] In this embodiment, the gantry 30 can be a fixed or movable structure, typically composed of columns, beams, and supporting structures. The height and width of the gantry 30 should be determined based on the actual operating environment and the dimensions of the battery module 200 to ensure sufficient operating space. The lifting hook 20 is installed on the beam of the gantry 30 and can move horizontally along the beam, while also having a lifting function. The lifting hook 20 can be an electric hoist or a hydraulic lifting device, possessing sufficient load-bearing capacity to meet the weight requirements of the battery module 200.

[0055] The lifting hole 115 of the module battery lifting device 10 is located on its central axis, on the side away from the adjustment through hole 111. The diameter of the lifting hole 115 should match the hook head size of the lifting hook 20 to ensure a secure connection. The edges of the lifting hole 115 can be rounded to reduce stress concentration and improve safety.

[0056] The working process of the module moving device 100 can be as follows: First, the module battery hoist 10 is connected to the battery module 200 through the first connector 12 and the second connector 13; then, the lifting hook 20 passes through the lifting hole 115 of the module battery hoist 10 to achieve the connection between the two; next, by controlling the lifting of the lifting hook 20 and the movement of the gantry 30, the battery module 200 is lifted and moved to the target position; finally, the lifting hook 20 is controlled to descend, and the battery module 200 is placed in the designated position to complete the moving operation.

[0057] The gantry 30 can be equipped with an electric drive system to achieve automatic or semi-automatic movement, improving work efficiency. The lifting hook 20 can be equipped with a precise height control system to ensure the smooth lifting and placement of the battery module 200. The entire module moving device 100 can be equipped with safety protection devices, such as overload protection and emergency stop buttons, to improve operational safety. The entire module moving device 100 may also include moving components, such as roller assemblies, to improve the flexibility of device movement.

[0058] The advantages of the module moving device 100 are: through the cooperation of the gantry 30 and the lifting hook 20, the battery module 200 can be moved flexibly; through the adjustment function of the module battery hoist 10, it can adapt to battery modules 200 of different sizes; through symmetrical design and solid connection, the safety and stability of the moving process are ensured.

[0059] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
