Description

Technical Field

[0001] This utility model relates to the field of battery pack hoisting technology, specifically an adjustable jig hook for assembling battery pack modules. Background Technology

[0002] In the assembly process of new energy battery pack modules, hoisting is a key process connecting various production stages, and its efficiency and safety directly affect the overall production rhythm. However, existing hoisting tools mostly rely on general-purpose hooks (such as lifting hooks and simple hooks), which have revealed many compatibility issues in practical applications.

[0003] Insufficient alignment accuracy: The lifting points of the battery pack modules are mostly pre-set special holes or lifting lugs. Their size, distribution density and compatibility with general lifting hooks are poor, making it difficult to quickly align the hooks with the lifting points. The position needs to be adjusted repeatedly, which seriously restricts the assembly efficiency.

[0004] Poor spatial adaptability: Battery pack module assembly scenarios often involve multi-layer stacking or operation in narrow spaces. Due to their fixed structure and redundant size, general-purpose hooks are prone to interference with surrounding components in confined spaces, which not only increases the difficulty of operation, but may also cause scratches on the battery cell casing or damage to the internal structure due to collisions.

[0005] Lack of versatility: Different battery module models have significant design differences, with varying spacing, depth, and angles of their lifting points. Traditional lifting hooks, due to their fixed dimensions, require dedicated tools for each module, resulting in large tool inventories, high switching costs, and the risk of assembly errors due to incorrect tool selection.

[0006] Significant safety hazards: The surface of the general-purpose metal hook is not insulated, and when it comes into contact with lithium battery cells, it may cause safety risks due to accidental conduction.

[0007] To address this, an adjustable jig hook for assembling battery pack modules is proposed. Summary of the Invention

[0008] The purpose of this invention is to provide an adjustable fixture hook for assembling battery pack modules, in order to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an adjustable fixture hook for assembling battery pack modules, comprising a fixing plate, a movable groove being provided below the fixing plate, a plurality of connecting plates being movably mounted on the movable groove, an upper rod being installed at the bottom end of the connecting plate, and through holes being evenly provided on the outer side of the upper rod;

[0010] The lower rod is movably installed inside the upper rod. The top of the lower rod is fitted with an elastic protrusion that matches the through hole, and the bottom of the lower rod is fitted with a hook.

[0011] Preferably, the connecting plate is U-shaped and is equipped with fixing bolts.

[0012] Preferably, the lower rod and the upper rod are hollow structures.

[0013] Preferably, the plurality of through holes are circumferentially arranged and evenly distributed on the outer side of the upper rod.

[0014] Preferably, a gripping groove is provided on the upper part of the fixing plate, and a handle is installed on the upper part of the gripping groove.

[0015] Preferably, the elastic protrusion is installed inside the upper end of the lower rod using a spring or a spring sheet.

[0016] Preferably, the outer surfaces of the fixing plate, connecting plate, upper rod, lower rod, and hook are all provided with insulating material.

[0017] Compared with the prior art, the beneficial effects of this utility model are: it can adapt to battery module mounting points with different spacings, and the hook spacing can be quickly adjusted by sliding and fixing the connecting plate along the moving groove, thus improving assembly efficiency.

[0018] The overall length of the upper and lower rods is adjustable. The hollow structure design allows the lower rod to slide inside the upper rod and be locked by elastic protrusions, adapting to hoisting needs at different depths, enhancing spatial adaptability, and avoiding interference with surrounding components when operating in confined spaces.

[0019] The hook angle is rotatable. With the cooperation of the through holes distributed around the circumference of the upper rod and the elastic protrusion of the lower rod, it can accurately handle different lifting points at different angles, thus improving versatility.

[0020] All metal parts have insulating material on their outer surfaces, which, combined with the wooden handle, prevents scratches on the battery cells and avoids the risk of leakage, thus improving operational safety. This makes them particularly suitable for lithium battery assembly scenarios. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-2 This utility model provides a technical solution: an adjustable tooling hook for assembling battery pack modules, including a fixing plate 1. The fixing plate 1 is made of aluminum alloy to ensure the strength and lightweight of the fixing device. A movable groove 4 is provided below the fixing plate 1. Multiple connecting plates 5 are movably installed on the movable groove 4. An upper rod 7 is installed at the bottom of the connecting plate 5. Through holes 8 are evenly provided on the outer side of the upper rod 7.

[0026] The lower rod 9 is movably installed inside the upper rod 7. The top end of the lower rod 9 is a hollow cylindrical structure, and the bottom end is located in a flat plate structure. An elastic protrusion 10 adapted to the through hole 8 is installed at the top end of the lower rod 9, and a hook 11 is installed at the bottom end of the lower rod 9.

[0027] like Figure 2 As shown: The connecting plate 5 is U-shaped, and a fixing bolt 6 is installed on the connecting plate 5. With the above arrangement, the bottom of the fixing plate 1 is located in the groove of the U-shaped connecting plate 5, and then the fixing bolt 6 passes through the connecting plate 5 and the moving groove 4. The connecting plate 5 is fixed in position by the fixing bolt 6 passing through the moving groove 4. When it is necessary to adjust the spacing of the hooks 11, the fixing bolt 6 is loosened, and the connecting plate 5 can slide laterally along the moving groove 4 until the hooks 11 are aligned with the lifting point of the battery module. Then the bolt is tightened to complete the fixation, thereby adapting to the lifting points of battery modules with different spacing.

[0028] like Figure 2 As shown: the lower rod 9 and the upper rod 7 are hollow structures; through the above settings, the lower rod 9 can move inside the upper rod 7. By adjusting the distance between the lower rod 9 and the upper rod 7, this device can be adapted to the hoisting of battery modules at different depths.

[0029] like Figure 1 and Figure 2 As shown: Multiple through holes 8 are circumferentially and evenly distributed on the outer side of the upper rod 7; with the above arrangement, when the lower rod 9 is rotated, the elastic protrusion 10 can be inserted into the through holes 8 at different angles, driving the hook 11 to rotate. For battery modules with lifting points distributed in the front-back, left-right, or diagonal directions, simply rotate the lower rod 9 to adjust the orientation of the hook 11 to accurately hook the lifting point, avoiding the risk of disengagement due to angular deviation.

[0030] like Figure 1 and Figure 2 As shown: A grip groove 2 is provided on the upper part of the fixed plate 1, and a handle 3 is installed on the upper part of the grip groove 2; with the above settings, the handle 3 is made of wood, making it more convenient for the staff to grip.

[0031] like Figure 2As shown: The elastic protrusion 10 is installed inside the upper end of the lower rod 9 using a spring or spring sheet; with the above configuration, the elastic protrusion 10 at the top of the lower rod 9, driven by the spring or spring sheet, can be inserted into the through hole 8 of the upper rod 7. During adjustment, press the elastic protrusion 10 to retract it, push the lower rod 9 to slide along the inner wall of the upper rod 7 to the required length, and the protrusion will automatically spring into the corresponding through hole 8 to complete the locking.

[0032] like Figure 1 As shown: The outer surfaces of the fixing plate 1, connecting plate 5, upper rod 7, lower rod 9 and hook 11 are all covered with insulating material; through the above settings, the outer surfaces of all metal parts are covered with insulating material, such as rubber, which can not only prevent scratching the battery cells during hoisting, but also prevent static electricity or leakage hazards, and is especially suitable for assembly scenarios of sensitive components such as lithium batteries.

[0033] Working principle: The connecting plate 5 is engaged with the bottom of the fixed plate 1. After loosening the fixing bolt 6, the connecting plate 5 can slide laterally along the moving groove 4. The position of the hook 11 is adjusted according to the spacing of the battery module hoisting points. After it is in place, the bolt is tightened to lock it, ensuring that the hook 11 is accurately aligned with the hoisting point.

[0034] The lower rod 9 is nested inside the hollow upper rod 7. Pressing the elastic protrusion 10 at the top of the lower rod 9 causes it to retract. Pushing the lower rod 9 along the inner wall of the upper rod 7 changes the total length to adapt to battery modules of different depths. After the position is determined, the elastic protrusion 10 automatically pops into the corresponding through hole 8 to complete the length locking.

[0035] The through holes 8 on the outer side of the upper rod 7 are distributed in a circle. When the lower rod 9 is rotated, the elastic protrusion 10 can be inserted into the through holes 8 at different angles, driving the hook 11 to rotate. This is suitable for battery modules with lifting points distributed in front and back, left and right, or diagonally, avoiding hook detachment due to angle deviation.

[0036] Workers use a wooden handle to hold the device. The insulating material on the outer surface prevents scratches on the battery cells and improves operational safety. Combined with the lightweight design of the aluminum alloy material, it enables efficient and safe hoisting and assembly of battery pack modules.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
