Each metal rod has multiple central frame assembly holes that extend vertically and horizontally along its length.

[0028] like Figure 1-3 As shown, the four corner frames 2 are integrally cast into a frame shape, and can be detachably connected to the X-direction metal pipe or Y-direction metal pipe of the central base frame 1 respectively, so as to achieve adjustable detachment and connection in the corner notch of the cross-shaped central base frame 1. Together with the four side rods 3, they form a rectangular outer contour frame. Each side rod 3 can be detachably connected between two adjacent corner frames 2.

[0029] like Figure 4 , 5 As shown, the corner frame 2 includes a square frame body and corner posts 23. The frame body includes two adjacent inner edge frames 21 that are detachably connected to the central base frame 1 in an adjustable position, and two adjacent outer edge frames 22 that are detachably connected to the corresponding side bars 3 in an adjustable position. The corner posts 23 are located at the corner between the two outer edge frames 22 and extend vertically.

[0030] In this embodiment, each of the two inner edge brackets 21 has a "U"-shaped lateral groove extending along its length for engaging with the corresponding metal fittings of the central base frame 1. Multiple horizontally extending inner edge mounting holes are distributed along the length of the "U"-shaped lateral grooves to facilitate engagement with the corresponding metal fittings of the central base frame 1 via screws. The "U"-shaped lateral grooves facilitate engagement with the central base frame 1 and also facilitate disassembly.

[0031] Each of the two outer edge frames 22 has an upper edge telescopic groove formed by the telescopic cavity and the anti-rotation opening of the edge rod, and a lower edge mounting groove formed by the fitting assembly cavity and the fitting anti-rotation opening. In this embodiment, the telescopic groove is a C-shaped groove with the opening facing upwards, and the fitting mounting groove is a T-shaped groove with the opening facing downwards. Multiple outer edge assembly holes extending vertically along the axis are distributed along the length of each groove. The C-shaped telescopic groove and the T-shaped fitting mounting groove extend along the length of the corresponding outer edge frame 22. The outer edge assembly holes are connected to the C-shaped telescopic groove and the T-shaped fitting mounting groove for easy screw installation.

[0032] The C-shaped expansion groove facilitates the installation of side rod 3, such as Figure 6 As shown, the side rod 3 includes a detachable insert rod 31 that is adjustable in length and position and is detachably connected to the C-shaped side rod telescopic groove, and an anti-rotation plate 32 integrally formed on the insert rod 31. A connecting neck is formed between the insert rod 31 and the anti-rotation plate 32, which is engaged at the anti-rotation opening of the side rod. The C-shaped side rod telescopic groove and the insert rod 31 are fitted with a clearance for easy insertion. Multiple side rod mounting holes are respectively provided on the insert rod 31 and the anti-rotation plate 32 along their length direction, so that the side rod 3 can be inserted into the corresponding position of the C-shaped side rod telescopic groove and fixed to the outer edge mounting hole by screws. The C-shaped side rod telescopic groove facilitates the installation of the side rod 3 and is also easy to disassemble, and is not easily deformed by force and jammed between the side rod 3 and the side rod 3.

[0033] The T-shaped accessory mounting slot facilitates the installation of various accessories, such as forklift fittings. Figure 4 , Figure 5 As shown, the fork fitting sleeve 4 includes a T-shaped or I-shaped strip that inserts into the T-shaped accessory mounting slot, a fork assembly plate integrally formed on the lower side of the T-shaped or I-shaped strip, and a fitting sleeve body integrally formed on the lower side of the fork assembly plate. Accessory mounting holes are provided vertically between the T-shaped or I-shaped strip and the fork assembly plate, allowing the fork fitting sleeve 4 to be inserted into the corresponding position of the T-shaped accessory mounting slot and fixed in place with the outer edge mounting holes using screws. Various modular fork fitting sleeves 4 are available to suit different forklifts for handling. The T-shaped accessory mounting slot facilitates the installation of various accessories and is also easy to disassemble, preventing deformation under stress and jamming between accessories.

[0034] like Figure 1-3 As shown, each corner frame has at least one pair of opposing inner edge frame 21 and outer edge frame 22 with peripheral stop mounting strips on their inner edges, and multiple peripheral stop mounting holes extending vertically along their length are distributed.

[0035] The modular battery pack multi-size applicable rack also includes multiple peripheral baffles 81, each detachably mounted on a corner frame 2 and adjustable in position, and multiple peripheral baffles 82, each detachably mounted on a corresponding peripheral baffle 81 and abutting against the perimeter of the battery pack. The peripheral baffles 81 are mounted on peripheral baffle mounting strips between a set of opposing inner edge frames 21 and outer edge frames 22. In this embodiment, two parallel peripheral baffles 81 are mounted on one corner frame 2, and all peripheral baffles 81 are parallel. Each peripheral baffle 81 is provided with a peripheral baffle 82 that can rotate around a vertical axis to accommodate the edge contours of different shaped battery packs. Of course, it is also possible to fix and modularize the peripheral baffles 82 to make various angle shapes to accommodate the edge contours of different shaped battery packs. The soft contact surfaces of all peripheral baffles 82 face the direction of the central battery pack to position the central battery pack in all directions.

[0036] like Figure 1, 2 As shown, the modular assembly battery pack multi-size applicable rack also includes at least two anti-jumping mechanisms 9 pressed on opposite sides of the battery pack. The anti-jumping mechanism 9 can be detached and installed at corresponding positions on the central base frame 1 or the side rod 3 in an adjustable position. The anti-jumping mechanism 9 can extend and retract vertically, including an anti-jumping lower part installed at the corresponding position on the central base frame 1 or the side rod 3, an anti-jumping upper part that can slide vertically and is positioned by engaging with corresponding insertion holes with pins, and an anti-jumping stop bolt slidably set on the anti-jumping upper part. The height of the anti-jumping upper part is determined by inserting pins into corresponding insertion holes, so that when the anti-jumping stop bolt extends, it presses against the upper surface of the battery pack to prevent the battery pack from moving upward.

[0037] like Figure 1 , 2 As shown, the modular assembly battery pack multi-size applicable rack also includes multiple pads 7 for supporting key stress points at the bottom of the battery pack. Each pad 7 has multiple mounting holes extending vertically. Each pad 7 includes a metal base pad 71 and an elastic soft pad 72 fixed to the metal base pad 71. Depending on the shape and stress points of the battery pack, the pads are installed at corresponding positions on the central base frame 1, with the mounting holes aligning with the corresponding mounting holes on the central base frame, and are fixed in place by screws.

[0038] like Figure 4 , Figure 5 , Figure 7 As shown, the lower part of the corner post 23 is detachably equipped with a stacking foot 5, and the upper part of the corner post 23 is equipped with a stacking frame 6 that can be unfolded upwards or folded downwards. The size of the stacking frame 6 is suitable for interlocking with the stacking foot 5, so that multiple racks can be stacked up and down. When stacking, the stacking frame 6 unfolds upwards, and the top of the stacking frame 6 of the lower rack is inserted into the stacking foot 5 of the upper rack, reducing the floor space occupied, and the forklift can transport multiple racks at one time, which is more convenient.

[0039] In this embodiment, the detachable connections that can be adjusted in position are all achieved through the assembly holes and screws, ensuring stable and secure assembly.
