[0002] As a power supply unit with extremely strong power supply capacity, the battery module is relatively large in size, so when transporting it, lifting equipment is usually used to transport the battery module. Since there are many specifications of battery modules, the sizes of battery modules vary.

[0003] At present, the traditional mass production lifting tools in the industry can often only be used for lifting battery modules of a specific size. If a battery module of a new specification is to be lifted, it is necessary to prepare suitable lifting tools again, which has poor compatibility and high manufacturing cost. In addition, different lifting tools need to be replaced in actual operation, which is complicated to operate and time-consuming.

[0004] Therefore, in the development process of the battery pack, when it is necessary to make samples and produce small batches, due to the small quantity, nylon ropes are used for simple lifting. Multiple nylon ropes and the good ductility and flexibility of the nylon ropes themselves are used to achieve simple lifting of small batches of battery modules of different specifications and sizes. However, when using nylon ropes for lifting, there is relative friction between the nylon ropes and the battery modules at the lifting position during the lifting process, which causes the nylon ropes to be damaged and broken. Therefore, their durability is low and the safety risk is relatively high. Utility Model Content

[0037] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0038] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0040] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0041] As a power supply unit with extremely strong power supply capacity, the battery module is relatively large in size, so when transporting it, lifting equipment is usually used to transport the battery module. Since there are many specifications of battery modules, the sizes of battery modules vary.

[0042] At present, the traditional mass production lifting tools in the industry can often only be used for lifting battery modules of a specific size. If a battery module of a new specification is to be lifted, it is necessary to prepare suitable lifting tools again, which has poor compatibility and high manufacturing cost. In addition, different lifting tools need to be replaced in actual operation, which is complicated to operate and time-consuming.

[0043] Therefore, in the development process of the battery pack, when it is necessary to make samples and produce small batches, due to the small quantity, nylon ropes are used for simple lifting. Multiple nylon ropes and the good ductility and flexibility of the nylon ropes themselves are used to achieve simple lifting of small batches of battery modules of different specifications and sizes. However, when using nylon ropes for lifting, there is relative friction between the nylon ropes and the battery modules at the lifting position during the lifting process, which causes the nylon ropes to be damaged and broken. Therefore, their durability is low and the safety risk is relatively high.

[0044] Therefore, in order to improve the durability when using simple lifting and reduce safety risks, this embodiment provides a lifting tool, and the lifting point device is used to connect the lifting hole 61 and the lifting rope 5.

[0045] Embodiment 1

[0046] like Figures 1 to 6 As shown, the hanging point device includes a hanging point body 1, a hook 2 and a limiting assembly 3. The hanging point body 1 is provided with a slide groove 11, a limiting groove 12 and a through hole connected to one end of the slide groove 11 near the hanging hole 61. The hook 2 is connected to the end of the hanging point body 1 with the through hole. The hook 2 is used to connect the hanging hole 61 and the hanging point body 1. The limiting assembly 3 includes a limiting piece 31 and a locking piece 32. The limiting piece 31 can be slidably inserted in the slide groove 11 and can extend out of the hanging point body 1 through the through hole. The part of the limiting piece 31 extending out of the hanging point body 1 abuts against the hook 2 to limit and fix the hook 2 in the hanging hole 61. The locking piece 32 is rotatably provided on the limiting piece 31 and can be screwed into the limiting groove 12 to be limited and fixed.

[0047] By providing a limit piece 31 that can slide in the slide groove 11 in the lifting point body 1 connected to the hook 2, when the hook 2 is connected to the lifting hole 61, the limit piece 31 is slid so that the limit piece 31 extends out of the lifting point body 1 and abuts against the hook 2, filling the space between the lifting hole 61 and the hook 2, and then the locking piece 32 on the limit piece 31 is screwed into the limit groove 12 for limit fixing, thereby the lifting point device is limit fixed in the lifting hole 61, thereby improving the stability during lifting, and at the same time avoiding direct connection between the lifting rope 5 and the lifting hole 61, reducing the risk of the lifting rope 5 breaking due to friction, and improving safety and durability.

[0048] The connection between the hook 2 and the suspension point body 1 can be a detachable connection, for example, the connection between the two is achieved by bolts, or a rod with an external thread is provided on the hook 2, and a threaded hole is provided on the suspension point body 1, and the connection between the two is achieved by threaded connection. The connection between the hook 2 and the suspension point body 1 can also be a fixed connection, for example, the hook 2 and the suspension point body 1 are connected by welding, or they can be manufactured by integral molding. There are many ways to connect the two, which will not be described here.

[0049] The lifting point device can be used in the lifting of various products. In this embodiment, it is mainly used for lifting and transporting battery modules. The lifting rope 5 is a nylon rope.

[0050] Optionally, the limiting assembly 3 includes a rotating shaft 33, the rotating shaft 33 is detachably connected to the limiting member 31, and the locking member 32 is rotatably sleeved on the rotating shaft 33. By providing the rotating shaft 33 detachably connected to the limiting member 31, the locking member 32 is sleeved on the rotating shaft 33, thereby realizing the rotational connection between the locking member 32 and the limiting member 31.

[0051] Specifically, the rotating shaft 33 includes a head and a rod, the rod is inserted into the limiting member 31 , and the locking member 32 is sleeved on the rod and located between the head of the rotating shaft 33 and the limiting member 31 .

[0052] In this embodiment, the rotating shaft 33 is a bolt, a threaded hole is provided on the limiting member 31, and the rotating shaft 33 is connected to the limiting member 31 by a threaded connection. A through hole is provided on the locking member 32, and the locking member 32 is sleeved on the rod of the bolt through the through hole. The head of the bolt limits the locking member 32 to prevent the locking member 32 from being detached from the rotating shaft 33.

[0053] In this embodiment, the slide 11 extends along the first direction, the limiting groove 12 extends along the second direction, the limiting groove 12 is connected to the slide 11, and is located on the side of the slide 11 close to the lifting hole 61, and the first direction is perpendicular to the second direction. By making the limiting groove 12 perpendicular to the slide 11, the locking force of the limiting member 31 after the locking member 32 is screwed into the limiting groove 12 is increased. Optionally, two limiting grooves 12 extending along the second direction can be provided on the suspension point body 1, and the two limiting grooves 12 are respectively connected to the two sides of the slide 11 along the second direction. By providing the limiting grooves 12 on both sides of the slide 11 along the second direction, no matter in which direction the locking member 32 is rotated, there is a corresponding limiting groove 12 corresponding to it, so that it is convenient for the operator to lock the limiting member 31 through the locking member 32. Optionally, the limiting groove 12 and the slide groove 11 may be connected or not connected. When the slide groove 11 is not connected to the limiting groove 12, an avoidance groove is provided on the locking member 32 to prevent the locking member 32 from interfering with the hanging point body 1 when the locking member 32 is screwed into the limiting groove 12. There is a certain angle between the limiting groove 12 and the slide groove 11, so that after the locking member 32 is screwed into the limiting groove 12, it can resist the gravity of the limiting member 31 itself, thereby achieving the locking of the limiting member 31.

[0054] Specifically, the slide groove 11 is a through groove, and the limiting groove 12 is a blind groove. By setting the limiting groove 12 as a blind groove, the locking member 32 located in the limiting groove 12 is limited, so as to avoid the locking member 32 rotating from the other side that the operator cannot observe due to vibration during hoisting, so that the limiting member 31 cannot be limited.

[0055] Optionally, the lifting point body 1 is further provided with an avoidance groove 13, which is connected to the slide groove 11 and is located on a side of the slide groove 11 away from the through hole, and the width of the avoidance groove 13 is greater than the width of the slide groove 11. By providing a wider avoidance groove 13 on a side of the slide groove 11 away from the limiting groove 12, it is convenient for the operator to grasp the locking member 32, and an operating space is reserved for the operator.

[0056] Alternatively, if Figure 4 As shown, the lifting point body 1 is also provided with a rope threading hole 14 for connecting with the lifting rope 5. By providing the rope threading hole 14 on the lifting point body 1, the lifting device can be in smooth contact with the lifting point body 1, reducing the wear of the lifting point body 1 on the lifting rope 5.

[0057] This embodiment also provides a lifting tool, which includes a lifting ring 4, multiple lifting point devices and a lifting rope 5 that can be connected to the multiple lifting point devices one by one. The lifting point bodies 1 of the lifting point devices are all connected to one end of the lifting rope 5, and the other ends of the lifting ropes 5 are all connected to the lifting ring 4.

[0058] The hoisting tool effectively avoids wear when using the hoisting rope 5 for hoisting by using the above-mentioned hoisting point device, thereby improving the safety during hoisting. In addition, the connection between the hoisting rope 5 and the hoisting hole 61 is reinforced by the above-mentioned hoisting point device, thereby improving the reliability during hoisting.

[0059] Alternatively, if Figure 1 , Figure 2 As shown, the lifting tool also includes an auxiliary lifting point 6, which is detachably connected to the part to be lifted and has a lifting hole 61. By setting the auxiliary lifting point 6, even if the part to be lifted does not have a lifting hole 61, the lifting work can be achieved by installing the auxiliary lifting point 6. In this embodiment, the lifting tool is used to lift a small batch of battery modules for sample preparation, so the auxiliary lifting point 6 is directly set on the shell of the battery module.

[0060] Furthermore, if Figure 6 As shown, the auxiliary hanging point 6 is also provided with a hanging notch 62 connected to the hanging hole 61. By providing the hanging notch 62 connected to the hanging hole 61 on the auxiliary hanging point 6, the connection between the hook 2 and the auxiliary hanging point 6 is facilitated.

[0061] Embodiment 2

[0062] Figure 7 The second embodiment is shown, wherein the components identical or corresponding to those of the first embodiment are marked with the corresponding reference numerals of the first embodiment. For the sake of simplicity, only the differences between the second embodiment and the first embodiment are described.

[0063] The difference is that, in addition to the auxiliary hanging point 6 structure given in the first embodiment, another structure of the auxiliary hanging point 6 can also be provided, and the auxiliary hanging point 6 includes an outer shell 63 and a plurality of partitions 64, the outer shell 63 is a hollow shell structure, and the plurality of partitions 64 are spaced apart in the outer shell 63, wherein the hanging hole 61 passes through the outer shell 63 and the plurality of partitions 64, thereby forming a plurality of hanging positions of different heights on the auxiliary hanging point 6, so as to facilitate the hanging of the hook 2 through the hanging positions of different heights, and realize the adjustment of the center of gravity of the hanging parts of different specifications and sizes.

[0064] When hoisting the battery module with the auxiliary hanging point 6 integrated on the shell, first move the hanging point body 1 to the auxiliary hanging point 6 by stretching the hanging rope 5, insert the hook 2 on the hanging point body 1 into the hanging hole 61 of the auxiliary hanging point 6, and adjust it according to the center of gravity of the battery module so that the hook 2 is connected with the corresponding hanging hole 61, and then the operator grasps the locking piece 32, slides the limiting piece 31 downward, and inserts it into the hanging hole 61 until the limiting piece 31 fixes the hook 2, and then rotates the locking piece 32 to screw the locking piece 32 into the limiting groove 12 to complete the fixation of the limiting piece 31, and then connects the hoisting equipment with the lifting ring 4 to realize the hoisting tooling of the battery module. After the hoisting is completed, rotate the locking piece 32 to screw it out of the limiting groove 12, and then slide the limiting piece 31 upward to unlock the hook 2 and the hanging hole 61, and then separate the hook 2 from the hanging hole 61.
