Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a battery module hoisting anti-detachment device. Background Technology

[0002] In recent years, with the rapid development of the new energy industry, the number of lithium battery packs has surged year after year. In the production process of lithium battery packs, the transfer and hoisting of modules are involved.

[0003] Existing module hoisting mechanisms typically only have simple hooks without anti-detachment devices, relying solely on gravity and simple engagement with the hook holes to achieve load-bearing capacity. This makes them highly susceptible to accidents such as falling due to manual operation or module swaying. Alternatively, an anti-detachment device may need to be designed based on features other than the module's lug holes. Such anti-detachment hook designs require the use of non-standard features such as auxiliary positioning holes, process grooves, or edge bosses to design locking mechanisms, resulting in poor versatility of the lifting mechanism and high adaptation costs. In addition, inserting and removing the anti-detachment pin is also extremely time-consuming. Utility Model Content

[0018] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] When hoisting battery modules, a simple connection is typically made between the hook 10 and the module mounting lug 40. After the hoisting equipment is connected to the hook 10, the battery module can be moved. The module mounting lug 40 is usually a slot with openings at the top and side of the battery module, providing space for the hook 10 to move. The hook 10 extends from the top opening and extends from the side opening, thus forming a simple mating connection with the battery module. Because the connection between the hook 10 and the module mounting lug 40 is unrestrained, the hook 10 is easily disengaged from the mounting lug 40 during movement due to manual operation, potentially causing the battery module to fall or other accidents.

[0020] See Figure 1-5 As shown, this embodiment discloses a battery module lifting anti-detachment device for use with the module hanging ear hole 40. The device includes a hook 10, a limiting member 20, and a limiting mating member 30, wherein: The hook 10 is used to connect to the module's hanging ear hole 40. The hook 10 has multiple notches 11 along its length. The limiting member 20 has an internal cavity 21. The hook 10 passes through the cavity 21. The limiting member 20 can move up and down relative to the hook 10. The limiting member 20 has a limiting hole 22 corresponding to the notch 11. The limiting fitting member 30 passes through the limiting hole 22 and is movably connected to the notch 11. When the limiting fitting member 30 is connected to the notch 11, the limiting member 20 and the hook 10 are locked. When the limiting fitting member 30 is separated from the notch 11, the limiting member 20 and the hook 10 are unlocked. After the hook 10 is connected to the module hanging ear hole 40, the limiting member 20 is fixed at the position of the hook 10 near the module hanging ear hole 40 to prevent the hook 10 from falling out of the module hanging ear hole 40. The limiting fitting member 30 is movably connected to the notch 11, making the locking or unlocking operation convenient. It not only ensures stable locking during hoisting, but also facilitates quick switching of states during loading, unloading and adjustment stages without affecting operational efficiency.

[0021] See Figure 1-3 As shown, the hook 10 body is coated with Teflon for insulation. Multiple notches 11 allow the limiting member 20 to be locked in multiple positions on the hook 10. In this embodiment, two notches 11 are provided: one near the hook portion 13 of the hook 10 and one away from the hook portion 13. When the hook 10 is connected to the module ear hole 40, the limiting member 20 connects with the notch 11 near the hook portion 13, preventing the hook 10 from disengaging from the module ear hole 40. When the limiting member 20 connects with the notch 11 away from the hook portion 13, the hook 10 can be removed from the module ear hole 40. Of course, depending on the size of the module ear hole 40, the number of notches 11 can be increased to increase the versatility of the device; this is not limited here.

[0022] See Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, the purpose of the limiting hole 22 is to provide a channel for the connection between the limiting fitting 30 and the notch 11. It can be a through hole on the limiting fitting 20, or it can be opened only on the side of the limiting fitting 20 facing the notch 11. There is no limitation here. The limiting fitting 20 includes a housing 200 and a cover plate 201. The housing 200 and the cover plate 201 are detachably connected by bolts. The housing 200 has slots on the top and bottom for the hook 10 to pass through. There is a cavity 21 between the housing 200 and the cover plate 201.

[0023] Further, see Figure 2 and Figure 9-10 As shown, the bottom sides of the limiting member 20 have extensions 23 arranged perpendicular to the hook 10, and the size of the extensions 23 is larger than the size of the module hook hole 40. The extensions 23 can limit the upward movement of the hook 10 and prevent the hook 10 from detaching from the module hook hole 40.

[0024] In one embodiment, the limiting fitting 30 can be a bolt, and the notch 11 is a threaded hole. The relative movement of the limiting fitting 20 and the hook 10 is restricted by the bolt engaging with the threaded hole. However, the bolt is time-consuming to tighten and is easy to lose.

[0025] Therefore, in another implementation, see Figure 3-4 and Figure 6 As shown, the limiting fitting 30 includes a sleeve 31, a spindle 32, and an elastic element 33. The sleeve 31 is detachably connected to the limiting hole 22. The elastic element 33 is disposed inside the sleeve 31. The spindle 32 passes through the elastic element 33 and is movably disposed inside the sleeve 31. The spindle 32 can move axially along the sleeve 31. A protrusion 320 is provided on the side of the spindle 32 facing the receiving cavity 21. The elastic element 33 achieves automatic reset, improving ease of use. When the spindle 32 is not subjected to external force, the elastic element 33 can push the spindle 32 to move axially along the sleeve 31 through its own elasticity, so that the protrusion 320 automatically extends into the notch 11 of the hook 10, realizing automatic locking between the limiting fitting 20 and the hook 10. When unlocking is required, force is applied to the spindle 32, the elastic element 33 is compressed, and the protrusion 320 moves out of the notch 11, realizing unlocking. During use, the limiting engagement 30 and the limiting engagement 20 only require force to be applied to the spindle 32 to achieve quick locking and unlocking, which saves time and effort. In addition, the limiting engagement 30 is always connected to the limiting engagement 20 during use to avoid loss.

[0026] In this embodiment, see Figure 8 As shown, a limiting groove 310 is formed inside the sleeve 31. One end of the elastic member 33 abuts against the bottom wall of the limiting groove 310, and the other end abuts against the protrusion 320. The elastic member 33 is a spring. The limiting groove 310 can prevent the spring from falling off the side of the sleeve 31 away from the limiting member 20, and is used to limit the movement space of the spring.

[0027] Further, see Figure 8 As shown, the diameter of the protrusion 320 is larger than the inner diameter of the sleeve 31 and smaller than the outer diameter of the sleeve 31. During the movement of the mandrel 32, when the protrusion 320 moves away from the notch 11, it will be abutted by the outer wall of the sleeve 31, thereby preventing the mandrel 32 from disengaging from the sleeve 31. The side of the limiting groove 310 facing the protrusion 320 has an opening, from which the spring can extend and abut against the protrusion 320. During the movement of the mandrel 32, the protrusion 320 drives the spring to move to compress or release the elasticity of the spring.

[0028] See Figure 5-6 As shown, in this embodiment, the sleeve 31 and the limiting hole 22 can be fixedly connected. However, in order to increase the flexibility of the device, it is preferable that the limiting hole 22 and the sleeve 31 are detachably connected. Specifically, a screw hole 220 can be opened in the limiting hole 22, and a thread can be opened on the sleeve 31. The sleeve 31 and the screw hole 220 are threadedly engaged, and a fastening nut 34 is also provided on the sleeve 31.

[0029] Referring to 6-7, in order to ensure that the protrusion 320 can remain connected to or separated from the notch 11, in one feasible embodiment, a stop 321 is provided on the side of the mandrel 32 away from the receiving cavity 21, and a stop position 311 is provided on the side of the sleeve 31 away from the receiving cavity 21. When the stop 321 and the stop position 311 are engaged, the protrusion 320 moves into the limiting hole 22. When the stop 321 and the stop position 311 are disengaged, the protrusion 320 moves out of the limiting hole 22. The stop portion 321 is a protrusion located on the side of the spindle 32 away from the protrusion 320. The stop position 311 is a groove formed at the end of the sleeve 31. The protrusion and the groove are adapted to each other. The spindle 32 is movably connected to the sleeve 31, so the spindle 32 can rotate inside the sleeve 31. When the spindle 32 moves and rotates until the protrusion and the groove are on the same straight line, the protrusion can be inserted into the groove. At the same time, the protrusion 320 is kept in a state of protruding from the surface of the sleeve 31 by the force of the spring, so that the protrusion 320 can always be connected to the notch 11. When the spindle 32 moves and rotates until the protrusion and the groove are perpendicular, the protrusion can abut against the top surface of the groove. The protrusion 320 presses against the elastic member 33, so that it is in a compressed state. At the same time, the protrusion 320 remains separated from the notch 11.

[0030] See Figure 6-7As shown, furthermore, the stability of the protrusion only abutting against the groove is poor, and it is easy to accidentally contact other devices and displace during movement, thereby causing the limiting member 20 to unlock from the hook 10. Therefore, in this embodiment, the stop part 321 is symmetrically provided with locking parts 322 on both sides, and the stop position 311 is symmetrically provided with locking grooves 312 on both sides. When the locking parts 322 and the locking grooves 312 are engaged, the stop part 321 and the stop position 311 remain in an unengaged state. The locking grooves 312 are perpendicular to the stop position 311. The engagement of the locking parts 322 and the locking grooves 312 provides a biting mechanical constraint on both sides of the mandrel 32 and the sleeve 31, avoiding accidental rotation or movement of the mandrel 32 due to vibration, collision or slight accidental contact during the hoisting process, thereby preventing the protrusion 320 from unexpectedly resetting. This structure significantly improves the stability of the unlocked state and effectively prevents accidental unlocking.

[0031] See Figure 6 and Figure 8 As shown, in this embodiment, the end of the mandrel 32 is provided with a handle 33. The size of the handle 33 is larger than the size of the mandrel 32. The handle 33 can improve the ease of operation, conform to ergonomics, improve the comfort of operation, and make it easier for the operator to apply force. Especially when the operator is wearing gloves or has oily hands, it can prevent slipping and conform to hand grip habits.

[0032] See Figure 1 and Figure 9-10 As shown, in this embodiment, a lifting ring 12 is detachably connected to the top of the hook 10. The lifting ring 12 is threadedly connected to the hook 10 and is used to connect lifting equipment. The detachable connection makes it easy to replace different models of lifting rings 12, increasing the versatility of the device.

[0033] Based on the above embodiments, the working principle of the module hoisting anti-detachment device of this utility model is as follows: With the hook 10 inserted through the module ear hole 40 and in the unlocked state, move the limiting member 20 to the notch 11 near the module ear hole 40. Rotate the handle 33 and move the spindle 32. The elastic member 33 is compressed. When the stop part 321 is opposite to the stop position 311, release the handle 33. The stop part 321 is inserted into the stop position 311. The elastic member 33 rebounds, causing the spindle 32 to move into the receiving cavity 21 of the limiting member 20. The protrusion 320 extends... When the hook 10 is removed, force is applied to the handle 33 to move the spindle 32 toward the handle 33 and rotate the spindle 32 until the stop part 321 and the stop position 311 are misaligned, and the locking part 322 and the locking groove 312 are opposite. When the handle 33 is released, the locking part 322 falls into the locking groove 312. At this time, the protrusion 320 separates from the notch 11, thereby unlocking the limiter 20 and the hook 10.

[0034] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
