Description

Technical Field

[0001] This invention relates to the field of battery module manufacturing technology, and specifically to a battery module hoisting structure. Background Technology

[0002] In the production process of lithium-ion battery modules, after multiple battery units are assembled into modules using structures such as end plates, clamps, or frames, they need to be transferred to the next workstation for boxing. Manual handling is not only laborious and time-consuming, but also poses certain dangers. Therefore, hoisting equipment is mostly used on the production line to assist manual operation and complete the transfer.

[0003] Existing lifting equipment using hooks mostly involves attaching the hook to slings or chains. During lifting, the hook is manually hooked onto the lifting hole of the battery module, and then lifted. Because battery modules are dense and heavy, it is usually necessary to install a hook at each of the four corners of the battery module. The manual hooking operation is tedious, and care must be taken to prevent the hooks from falling off during lifting, resulting in low production efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a battery module hoisting structure that can quickly realize the connection between the hook and the battery module, reduce the amount of manual operation and improve production efficiency.

[0005] To address the aforementioned technical problems, this invention provides a battery module hoisting structure, comprising a battery module and a hoisting body positioned directly above the battery module. Each battery module has an end plate on one side, and each end plate has two hanging parts. The hoisting body has a hook positioned opposite each hanging part. Each hook is L-shaped, comprising a vertical rod and a horizontal hanging end. The horizontal hanging end is used to engage with the hanging part. The hoisting body is equipped with a moving mechanism that drives the four hooks to move horizontally, causing each horizontal hanging end to be vertically offset or vertically aligned with its corresponding hanging part.

[0006] In the non-working state, each of the horizontal hanging ends is located directly above the corresponding hanging part; during hoisting, as the lifting body drives the hook to descend vertically, the moving mechanism first moves the hook and then resets it, so that the horizontal hanging end is first vertically offset from the hanging part, and then restored to vertical alignment with the corresponding hanging part, thereby realizing that the horizontal hanging end of each hook moves to the bottom of the corresponding hanging part and engages.

[0007] In the aforementioned battery module hoisting structure, the L-shaped hook, rigidly fixed directly to the hoisting body, enables automatic engagement between the hook and the hanging part. During the hook's descent, a moving mechanism horizontally reciprocates once, cleverly avoiding contact between the horizontal hanging end and the hanging part on the end plate. The hook then moves to the bottom of the hanging part for engagement, eliminating the need for manual engagement of the hook and hanging part individually. This significantly reduces worker workload, simplifies the hoisting process, and improves production efficiency. Furthermore, the hook and hanging part are less prone to detachment, ensuring a stable and reliable hoisting process. In addition, the entire structure is simple and ingeniously designed.

[0008] As an improvement to the battery module hoisting structure of the present invention, the hanging part is formed by a horizontal plate-like structure on the end plate body, and the bottom of the hanging part is provided with a hollow space, which is used to accommodate the horizontal hanging end.

[0009] By setting a horizontal plate-like structure with a hollowed-out bottom on the main body of the end plate, a suitable match is achieved for the horizontal hanging end of the L-shaped hook, which is a clever structural design.

[0010] Furthermore, on the end plate, each of the hanging parts has a vertical channel on one side. The bottom of the channel is lower than the hanging part, and the side is connected to the hollow space, so that the horizontal hanging end extends vertically into the channel and moves horizontally to engage with the hanging part.

[0011] By pre-reserving a channel for the hook to pass through on the end plate adjacent to the hanging part, the horizontal hanging end can be lowered to a height lower than the hanging part and enter the hollow space for attachment, saving hoisting space. Alternatively, an opening can be made on the side of the hollow space to penetrate the side of the end plate, allowing the horizontal hanging end to move horizontally to the outside of the end plate for lowering and avoidance. Compared to the above-mentioned solution using a channel, this will occupy more workspace.

[0012] As another improvement to the battery module hoisting structure of the present invention, the moving mechanism can be fully automated by using a motor drive mechanism and a control system, or it can be manually operated by a worker.

[0013] Considering factors such as cost, a preferred implementation structure for manual operation by workers is as follows:

[0014] The moving mechanism includes two slide rods respectively positioned opposite the two end plates. Two sliders are slidably mounted on each slide rod. A first compression spring is mounted on the slide rod between the two sliders. A hook is fixed to the bottom of each slider, and a hand-operated moving rod is mounted on the side of each slider. The ends of two opposing hand-operated moving rods on the two slide rods are connected to each other and move synchronously. Preferably, the hand-operated moving rods are arranged perpendicular to the slide rods; the two hooks on the same slide rod are arranged symmetrically in mirror image.

[0015] The worker manually operates two hand-operated moving rods, which drive the slider to move relative to the rod, compressing the first compression spring and simultaneously moving the hook horizontally. After the horizontal hanging end of the hook descends to the bottom of the hanging part, the hand-operated moving rods are released. Under the action of the first compression spring, the slider and hook are pushed back to their original positions, realizing the engagement of the hook with the hanging part. The operation is simple, time-saving and labor-saving.

[0016] Furthermore, the slider is an inverted F-shaped block, including a first sliding part, a second sliding part, and a hand-pinching moving part. The first sliding part and the second sliding part are arranged vertically at intervals, and their tops are slidably connected to the slide rod. The hand-pinching moving part is arranged horizontally at the bottom of the slide rod. The top end of the vertical hanging rod is fixed to the bottom surface of the hand-pinching moving part between the first sliding part and the second sliding part. The hand-pinching moving rod is fixed to the side of the end of the hand-pinching moving part away from the first sliding part.

[0017] Furthermore, the lifting device body is provided with an adjustment mechanism, which is used to adjust the distance between the two sliding rods, thereby adjusting the distance between the hooks at both ends of the lifting device body. It is suitable for lifting battery modules of various lengths and sizes, and has strong versatility.

[0018] In the above-mentioned technical solution employing an adjustment mechanism, the lifting device body includes a support rod assembly composed of a pair of parallel spaced columns. A base is fixed in the middle of the support rod assembly, and a lifting ring is provided on the top of the base. Side plates are symmetrically fixed at both ends of the support rod assembly. A sliding plate is provided between each side plate and the base. The two ends of the sliding plate are slidably mounted on the columns, and a screw is threadedly connected to the middle of the sliding plate. The two ends of the screw are rotatably mounted on the side plate and the base, respectively. A drive motor is provided on the base to drive the screw to rotate. The sliding rod is fixed on the top surface of the sliding plate.

[0019] The screw and slide block mechanism is formed on the main body of the lifting device by a slide plate and a screw. As an adjustment mechanism, the screw transmission has high precision and high reliability, which makes the adjustment stable and accurate.

[0020] Preferably, the column is arranged along a plane perpendicular to the end plate, and the screws on both sides of the base rotate synchronously.

[0021] Furthermore, both ends of the slide plate are provided with floating positioning mechanisms. The floating positioning mechanism includes floating blocks arranged at a certain distance on one side of the end of the slide plate, guide rods fixed on the end of the slide plate, and a number of positioning holes arranged at intervals on the column. The floating blocks are slidably arranged on the column. The guide rods are parallel to the column and slide through the floating blocks. A second compression spring is provided on the outside of the guide rod between the floating blocks and the slide plate. The floating blocks are provided with positioning pins, which are used to insert from the floating blocks into a certain positioning hole on the column.

[0022] The floating positioning mechanism is used to assist in the positioning of the slide plate, reducing the impact on the threaded pair of the slide plate and screw caused by the shaking of the suspended battery module during the hoisting process.

[0023] Preferably, there are four guide rods distributed at the four corners of the floating block, and a stop is provided at the end of the guide rod that extends out of the floating block to prevent the floating block from slipping off the guide rod.

[0024] Furthermore, the rod of the hand-pinching moving rod slides through the slider and extends to the side plate in a direction perpendicular to the end plate, and the end of the hand-pinching moving rod is slidably disposed on the side plate.

[0025] Preferably, a zigzag protrusion is provided at the connection point of the two hand-operated movable rods to avoid the base.

[0026] As a further improvement to the battery module hoisting structure of the present invention, a guide pin is provided on each of the mounting holes on the slide plate that are opposite to the end plate. The guide pin is adapted to the mounting hole of the end plate, and during hoisting, the guide pin is movably inserted into the corresponding mounting hole of the end plate.

[0027] During hoisting, as the main body of the lifting device descends, the guide pin is first inserted into the mounting hole of the end plate to ensure that the main body of the lifting device is aligned vertically with the battery module. Most importantly, it ensures that the hook is in the correct position and that the guide pin is inserted along the mounting path to guide the subsequent descent of the main body of the lifting device.

[0028] In summary, the battery module hoisting structure described above eliminates the need for manual attachment of hooks to the hanging parts, significantly reducing the workload for workers. The manual operation is simple, the hoisting process is streamlined, and production efficiency is improved. The span between hooks can be adjusted, making it suitable for various battery module sizes. The entire structure is simple and ingeniously designed. Attached Figure Description

[0040] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions of the embodiments are for the purpose of helping to understand the present invention, but do not constitute a limitation thereof.

[0041] Example 1

[0042] Figure 1-7This invention illustrates a battery module hoisting structure. For example... Figure 1-6 As shown, the battery module hoisting structure includes a battery module 1 and a hoisting body 2 located directly above the battery module 1. An end plate 3 is provided on each side of the battery module 1, and two hanging parts 31 are provided on each end plate 3. A hook 4 is provided on the hoisting body 2 opposite to each hanging part 31. The hook 4 is L-shaped and includes a vertical hanging rod 41 and a horizontal hanging end 42. The horizontal hanging end 42 is used to engage with the hanging part 31. A moving mechanism is provided on the hoisting body 2. The moving mechanism is used to drive the four hooks 4 to move horizontally, so that each horizontal hanging end 42 is vertically offset or vertically aligned with the corresponding hanging part 31.

[0043] During hoisting, the lifting mechanism is activated to move the lifting body 2 downwards, causing the four hooks 4 to descend vertically. The moving mechanism first moves each hook 4 horizontally so that the horizontal hanging end 42 is vertically offset from the hanging part 31 and descends to a height lower than the hanging part 31. Then, the moving mechanism resets the hook 4 horizontally so that it is vertically aligned with the corresponding hanging part 31. In other words, the horizontal hanging end 42 of each hook 4 is moved to the bottom of the corresponding hanging part 31 to achieve attachment and hoisting, without the need for complicated manual operation.

[0044] like Figure 5 As shown, the hanging part 31 is formed by a horizontal plate-like structure on the main body of the end plate 3, and the bottom of the hanging part 31 is provided with a hollow space 32 for accommodating the horizontal hanging end 42. On the end plate 3, each hanging part 31 has a vertical channel 33 on one side. The bottom end of the channel 33 is lower than the hanging part 31, and the side is connected to the hollow space 32, so that the horizontal hanging end 42 can be vertically inserted into the channel 33 and moved horizontally to engage with the hanging part 31.

[0045] A channel 33 is reserved on the end plate 3 adjacent to the hanging part 31 for the hook 4 to pass through, so that the horizontal hanging end 42 can be lowered to a height lower than the hanging part 31 and enter the hollow space 32 for hanging. The whole action is completed within the end plate 3, saving hoisting station space.

[0046] like Figure 1 and 2 The diagram shows a structure for manually operating a movable hook 4. The moving mechanism includes two slide rods 51 respectively positioned opposite the two end plates 3. Each slide rod 51 has two sliders slidably mounted on it. A first compression spring 53 is mounted on the slide rod 51 between the two sliders 52. A hook 4 is fixed to the bottom of each slider 52. A hand-operated moving rod 54 is mounted on the side of each slider 52. The ends of the two opposing hand-operated moving rods 54 on the two slide rods 51 are connected to each other and move synchronously. The hand-operated moving rods 54 are arranged in a direction perpendicular to the slide rods 51.

[0047] Optionally, as Figure 8 shown, the two hooks 4 on the same sliding rod 51 are arranged symmetrically with respect to the mirror image, in the shape of "儿", and the sliders 52 are also arranged symmetrically with respect to the mirror image.

[0048] A sliding mechanism is composed of the sliding rod 51 and the slider 52. The human hand acts on the hand-held moving rod 54 to drive the two sliders 52 to move relative to each other on the sliding rod 51, and drives the hook 4 fixed to the bottom of the slider 52 to move relatively, so that the horizontal hanging end 42 of the hook 4 moves to the top of the channel 33. In this way, during hoisting, the horizontal hanging end 42 can move to a height lower than the hanging part 31, and then the worker releases the hand-held moving rod 54. Under the restoring force of the first compression spring 53, the horizontal hanging end 42 moves horizontally again with the slider 52, the slider 52 returns to the initial position on the sliding rod 51, and the horizontal hanging end 42 moves to the bottom of the horizontal hanging part 31 to achieve engagement. The operation is simple, time-saving and labor-saving.

[0049] As Figure 7 shown, the slider 52 is in the shape of an inverted F-shaped block, including a first sliding part 521, a second sliding part 522 and a hand-held moving part 523. The first sliding part 521 and the second sliding part 522 are arranged vertically at intervals, and the tops of both are slidably connected to the sliding rod 51. The hand-held moving part 523 is horizontally arranged at the bottom of the sliding rod 51. The top end of the vertical hanging rod 41 is fixed on the bottom surface of the hand-held moving part 523 between the first sliding part 521 and the second sliding part 522. The hand-held moving rod 54 is fixed on the side surface of the end of the hand-held moving part 523 far from the first sliding part 521.

[0050] The top end of the vertical hanging rod 41 is fixed to the bottom of the groove between the first sliding part 521 and the second sliding part 522 by bolts, avoiding the structure of the sliding rod 51. The hand-held moving part 523 has a certain length, so that the distance between the two hand-held moving rods 54 is kept relatively close, which is convenient for manual operation by workers. During hoisting, the two hand-held moving rods 54 are directly held tightly together by hand to drive the slider 52 to move. At the same time, the hand-held moving part 523 also has a certain limiting effect.

[0051] Optionally, the lifting mechanism can be a balance hoist.

[0052] In order to improve the versatility of the hoisting structure, an adjusting mechanism is provided on the hoisting tool main body 2. The adjusting mechanism is used to adjust the distance between the two sliding rods 51, and further realizes the adjustment of the distance between the hooks 4 at both ends of the hoisting tool main body 2, which is applicable to the hoisting of battery modules 1 with various length size specifications and has strong versatility.

[0053] Specifically, as Figure 1-3As shown, the lifting device body 2 includes a support rod assembly composed of a pair of parallel spaced columns 21. A base 22 is fixed in the middle of the support rod assembly, and a lifting ring 23 is provided on the top of the base 22. Side plates 24 are symmetrically fixed at both ends of the support rod assembly. A sliding plate 25 is provided between each side plate 24 and the base 22. The two ends of the sliding plate 25 are slidably mounted on the columns 21, and a screw 26 is threadedly connected to the middle of the sliding plate 25. The two ends of the screw 26 are rotatably mounted on the side plate 24 and the base 22, respectively. A drive motor 27 is provided on the base 22 to drive the screw 26 to rotate. A sliding rod 51 is fixed on the top surface of the sliding plate 25. The columns 21 are arranged along the plane direction perpendicular to the end plate 3, and the screws 26 on both sides of the base 22 rotate synchronously.

[0054] Optionally, the base 22 consists of a channel block and a base plate. The channel block is arranged upside down in the middle of the support rod assembly along the direction of the vertical column 21, and the base plate is fixed to the bottom of the channel block. Two columns 21 pass through and are fixed to the two ends of the channel block. A screw 26 is rotatably mounted on the side wall of the channel block, with its end extending into the interior of the channel block. A drive motor 27 is fixed to the top surface of the channel block, and the output shaft of the drive motor 27 extends into the interior of the channel block to drive the screw 26. A reinforcing U-shaped cover is fixed to the outside of the drive motor 27, which protects the drive motor 27 and facilitates the fixing of the lifting ring 23 to the top for easy lifting. A Z-shaped protrusion is provided at the connection of the two hand-operated moving rods 54 to avoid the U-shaped cover on the base 22.

[0055] like Figure 2 and Figure 9 As shown, both ends of the slide plate 25 are provided with floating positioning mechanisms. The floating positioning mechanism includes floating blocks 61 arranged at a certain distance on one side of the end of the slide plate 25, guide rods 62 fixed on the end of the slide plate 25, and a number of positioning holes 65 arranged at intervals on the column rod 21. The floating blocks 61 are slidably arranged on the column rod 21. The guide rods 62 are parallel to the column rod 21 and slide through the floating blocks 61. A second compression spring 63 is provided on the outside of the guide rods 62 between the floating blocks 61 and the slide plate 25. A positioning pin 64 is provided on the floating blocks 61. The positioning pin 64 is used to insert into a positioning hole 65 on the column rod 21 from the floating blocks 61.

[0056] The floating positioning mechanism provides auxiliary positioning for the slide plate 25, reducing the impact on the threaded pair between the slide plate 25 and the screw 26 caused by the shaking of the suspended battery module 1 during the hoisting process.

[0057] Optionally, there are four guide rods 62, distributed at the four corners of the floating block 61, and a stop is provided at the end of the guide rod 62 that extends out of the floating block 61 to prevent the floating block 61 from slipping off the guide rod 62.

[0058] Optional, such as Figure 1 and Figure 8 As shown, the rod of the hand-operated moving rod 54 slides along the direction of the vertical end plate 3, passes through the slider 52, and extends to the side plate 24. The end of the hand-operated moving rod 54 is slidably set on the side plate 24. In this way, the hand-operated moving rod 54 has two sliding supports, which guide and restrict the movement of the hand-operated moving rod 54 and improve the stability of manual operation by the worker.

[0059] Specifically, a fixed sliding block is provided at the end of the hand-grip movable rod 54, and a sliding rod is provided on the side plate 24 for the fixed sliding block to slide. The fixed sliding block slides freely on the sliding rod to support and guide the movement of the hand-grip movable rod 54.

[0060] like Figure 8 As shown, a guide pin 7 is provided at each mounting hole on the slide plate 25 opposite to the end plate 3. The guide pin 7 is adapted to the mounting hole of the end plate 3. During hoisting, the guide pin 7 is inserted into the corresponding mounting hole of the end plate 3.

[0061] During hoisting, as the lifting device body 2 descends, the guide pin 7 is first inserted into the mounting hole of the end plate 3 to ensure that the lifting device body 2 and the battery module 1 are aligned vertically. Most importantly, this ensures that the hook 4 is in the correct position. The guide pin 7 is inserted along the mounting path to guide the subsequent descent of the lifting device body 2.

[0062] The present invention also provides a method of using the above-mentioned battery module hoisting structure, comprising:

[0063] Step 1: The lifting device body 2 moves the hook 4 downwards;

[0064] Step 2: Manually pinch the opposing hand-operated moving rods 54 on both sides of the base 22 together;

[0065] Step 3: Once the horizontal hanging end 42 of the hook 4 has moved to the bottom of the horizontal hanging part 31, release the squeezing hand on the moving rod 54 to move the horizontal hanging end 42 to the bottom of the horizontal hanging part 31, thus achieving hooking.

[0066] Step 4: The lifting device body 2 drives the hook 4 to move upward, thus achieving lifting.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit its scope of protection. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that after reading the present invention, they can still make various changes, modifications or equivalent substitutions to the specific implementation of the invention, but these changes, modifications or equivalent substitutions are all within the scope of protection of the pending claims of the invention.
