Description

Technical Field

[0001] This utility model relates to the technical field of battery pack production equipment, specifically to a PACK battery pack hoisting fixture. Background Technology

[0002] In current battery pack production, most battery packs are lifted using tools such as chains and lifting rings. During lifting, the center of gravity of the lifting equipment is not the same as that of the battery pack, which causes the battery pack to tilt severely during lifting, easily damaging the appearance of the battery pack. In addition, the lifting points of these tools are of varying heights and difficult to adjust, resulting in uneven stress on each lifting point, which poses a risk of breakage of the lifting rings and chains.

[0003] A prior art battery pack hoisting structure includes a hoisting assembly and a stabilizing assembly. The hoisting assembly includes two parallel hoisting beams with multiple hoisting top plates between them. First mounting seats are distributed at the bottom of the hoisting beams, and first sliding grooves are formed on the first mounting seats. A hoisting chain assembly slides along the first sliding grooves to the corresponding positions and is then limited by a limiting assembly. The stabilizing assembly includes a fixed mounting plate with fixing plates around its perimeter. Threaded through holes are formed on the fixing plates, and adjusting screws pass through these holes. One end of the adjusting screw is fitted with a limiting plate, and the other end is fitted with the fixing assembly. This invention can improve the stability of the battery pack during hoisting. However, this battery pack hoisting structure cannot adjust the center of gravity, and the center of gravity of the battery pack is still inconsistent with the center of gravity of the overall structure, resulting in uneven stress at various hoisting points.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0024] Please see Figures 1 to 4A battery pack lifting fixture includes a square bracket 10, a threaded lifting rod 20, and a hook 30. The upper end of the threaded lifting rod 20 is movably mounted on the square bracket 10 via a mounting component 21. The hook 30 is located at the bottom of the threaded lifting rod 20. The square bracket 10 has several lifting holes 131, all located on the same plane. The square bracket 10 is connected to a lifting device through the lifting holes 131. By connecting any two lifting holes 131, the lifting device can adjust the lifting center of gravity of the square bracket 10, thereby maintaining the balance between the lifting center of gravity of the square bracket 10 and the center of gravity of the battery pack, ensuring balanced lifting of the battery pack, preventing tilting during lifting, and avoiding scraping of the battery pack.

[0025] Please see Figure 1 and Figure 2 The square support 10 includes two relatively parallel first square tubes 11 and two relatively parallel second square tubes 12. The second square tubes 12 are mounted on the first square tubes 11 and are fixedly connected by bolts. Specifically, each end of the first square tube 11 is provided with a plurality of first adjustment holes 111. The first adjustment holes 111 extend along the length of the first square tube 11 and are symmetrical about the first square tube 11. The second square tubes 12 are connected to the first adjustment holes 111 by bolts, thus fixing the second square tubes 12 to the first square tubes 11.

[0026] By moving the second square tube 12 and changing the connection position between the second square tube 12 and the first adjustment hole 111, the center of gravity of the entire square bracket 10 can be adjusted.

[0027] A lifting seat 13 is provided between the two first square tubes 11, and lifting holes 131 are provided on the lifting seat 13. In order to facilitate the adjustment of the center of gravity of the square support 10, several lifting holes 131 are provided at the middle of the two first square tubes 11 at both ends of the lifting seat 13, and the extension direction of the lifting holes 131 is perpendicular to the length direction of the first square tube 11.

[0028] By connecting the lifting device to the lifting holes 131 at different positions, the lifting center of gravity of the square bracket 10 can be changed, thereby adjusting the center of gravity of the square bracket 10.

[0029] The length direction of the first square tube 11 is defined as the length direction of the square bracket 10, and the length direction of the second square tube 12 is defined as the width direction of the square bracket 10. By changing the position of the lifting hole 131 of the lifting device, the lifting center of gravity of the square bracket 10 is changed in the length direction. By changing the connection position of the second square tube 12 on the first square tube 11, the lifting center of gravity of the square bracket 10 is changed in the width direction. By combining the two, the center of gravity of the square bracket 10 can be flexibly adjusted so that the center of gravity of the square bracket 10 is balanced with the center of gravity of the battery pack, so that the battery pack is lifted in a horizontal state, avoiding tilting and improving lifting stability.

[0030] Please see Figure 2 and Figure 3 A mounting member 21 is fitted onto the second square tube 12. The mounting member 21 is square-ring shaped and is fixedly connected to the second square tube 12 by a spring plug 23. Second adjustment holes 121 are provided at both ends of the second square tube 12, extending along the length of the second square tube 12. The second adjustment holes 121 at both ends of the second square tube 12 are symmetrically arranged, and the mounting member 21 is connected to the second square tube 12 through the second adjustment holes 121. The upper end of the threaded rod 20 is connected to the bottom of the mounting member 21, and a hook 30 is provided at its lower end for connecting the battery pack. In this embodiment, four mounting members 21 are provided, located at both ends of the two second square tubes 12 respectively, and the four hooks 30 below the mounting members 21 are used to suspend the battery pack.

[0031] By changing the installation position of the mounting component 21 on the second square tube 12, changing the installation position of the second square tube 12 on the first square tube 11, changing the distance between each threaded lifting rod 20, and changing the range around which the four hooks 30 surround, the system can be adapted to the hoisting of battery packs of different sizes.

[0032] The hook 30 is connected to the square bracket 10 via a threaded rod 20. The hook 30 includes a lifting section 31, a connecting arm 32, an extension arm 33, and a load-bearing section 34. The connecting arm 32 is inclined, with its upper end connected to the lifting section 31 and its lower end connected to the extension arm 33. The extension arm 33 is vertically positioned, with its bottom connected to the load-bearing section 34. The connecting arm 32, extension arm 33, and load-bearing section 34 are connected to form an inverted C-shape. The battery pack flange overlaps the load-bearing section 34 and is fixed to it by a movable pin 35. Preferably, the load-bearing section 34 is horizontally positioned so that the battery pack flange is horizontally overlapped on the load-bearing section 34, improving the load-bearing stability of the hook 30. In this embodiment, the hook 30 is an integral mechanism.

[0033] Preferably, the lifting part 31 is provided with a lifting hole 311 for connecting the threaded lifting rod 20, and the movable pin 35 is located directly below the lifting hole 311. The midpoint of the lifting hole 311 is located on the central axis of the movable pin 35, thereby improving the load-bearing capacity and stability of the hook 30.

[0034] In this embodiment, the threaded lifting rod 20 is a turnbuckle. By rotating it, the overall length of the threaded lifting rod is changed, and the height of the bottom hook 30 of the threaded lifting rod 20 is changed, thereby changing the connection position between the battery pack flange and the bearing part 34. This adjusts the force on the hook 30 to ensure that the force direction of each hook 30 is vertical and that the force on each hook 30 is basically the same, so that the battery pack is kept balanced during lifting.

[0035] Preferably, a universal lifting ring 22 is provided below the mounting component 21, and the upper end of the threaded rod 20 is connected to the universal lifting ring 22 so as to adjust the lifting length of the threaded rod 20 by rotation.

[0036] Preferably, the bearing portion 34 is equipped with anti-slip pads to prevent accidental tilting and slippage during hoisting. The battery pack edges are coated with adhesive to prevent the hook from scraping the battery pack during lifting and to protect the battery pack's appearance.

[0037] As another implementation method, such as Figure 5 As shown, an isosceles triangular hanger 40 is provided between the hook 30 and the threaded rod 20. The top of the hanger 40 is connected to the bottom of the threaded rod 20, and two hooks 30 are symmetrically arranged at both ends of its bottom. The two hooks 30 are respectively connected to the battery pack, increasing the number of lifting points from four to eight. This reduces the force on a single hook 30, prevents the battery pack from buckling and deforming, and avoids damage to the battery pack's appearance. It is suitable for lifting larger and heavier battery packs. The threaded rod 20 can adjust the height of both hooks 30 simultaneously, and the isosceles triangular structure of the hanger helps maintain the force balance between the two hooks 30.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
