[0027] The main support 10 is used to provide support for the bracket 20. In the embodiment, the main support 10 includes a plurality of main bodies 11 arranged vertically, and the main bodies 11 are arranged at intervals in the same main support 10. Two main supports 10 are arranged oppositely to support different pallets 21 in the same group of brackets 20. The bracket 20 is horizontally fixed on the main support 10. Specifically, each group of brackets 20 includes two pairs of pallets 21 arranged horizontally oppositely. In each group of brackets 20, the two pallets 21 are arranged oppositely on the two main supports 10, and the pallet 21 is perpendicular to and fixedly connected with the main member.

[0028] Preferably, the bottom of the main support 10 is provided with a grid-shaped bottom beam structure 40 formed by a plurality of steel materials arranged alternately to connect the plurality of main bodies 11 and improve the stability of the main support 10. The bottom of the bottom beam structure 40 is provided with four universal wheels 50 to facilitate the staff to push the main support 10 to transport the battery pack 80.

[0029] Please refer to Figure 2 The pallet 21 has an L-shaped structure including a mounting plate 212 and a support plate 211 arranged perpendicularly to each other. The mounting plate 212 is used to connect the main member, and the support plate 211 is used to support the battery pack 80 or the high-voltage box 90. In order to improve the support strength of the support plate 211 and avoid deformation of the pallet 21, a trapezoidal corner code 215 is further arranged on the support plate 211. The two vertical side plates of the corner code 215 are fixedly connected with the support plate 211 and the main body 11, respectively.

[0030] In the embodiment, a group of brackets 20 is used to support a plurality of battery packs 80. The two pallets 21 support the battery pack 80 at both ends in the length direction of the battery pack 80. In contrast, the length of the pallet 21 should be greater than or equal to the width of the battery pack 80, so that the pallet 21 can completely cover the length of the battery pack 80. Further, in order to fix the battery pack 80 and avoid movement of the battery pack 80 on the bracket 20 during transportation, a connecting hole 214 is formed on the support plate 211. The connecting hole 214 is a waist-shaped hole extending along the width direction of the support plate 211. The connecting hole 214 can be suitable for fixing battery packs 80 of various sizes, and at the same time, it can absorb the installation error when the battery pack 80 is connected to the support plate 211.

[0031] The actual production of the battery pack 80 on the tab is usually set in the length direction of the battery pack 80, so when the battery pack 80 is placed on the bracket 20, the battery pack 80 tab is also above the support plate 21.

When the battery pack 80 is placed on the bracket 20, the limiting plate 213 is above the battery pack 80 tab, and the battery pack 80 is limited in the height direction. Preferably, in order to avoid the tab from being damaged by colliding with the limiting plate 213, a buffer pad is arranged on the side of the tab facing the supporting plate 211, which can be a rubber pad or a sponge pad.

[0032] Please refer to Figure 3 and Figure 4 , the support plate 21 is also provided with a fixing member 31 and a stop member 32 for fixing the high-pressure box 90, and the fixing member 31 and the stop member 32 are arranged on the supporting plate 211. Specifically, the fixing member 31 includes a bottom plate 311, a connecting plate 312 and a positioning plate 313 connected together, the bottom plate 311 is connected to the supporting plate 211 by riveting a nut, and the connecting plate 312 and the positioning plate 313 are arranged vertically in an L shape. The outer wall of the high-pressure box 90 is provided with an L-shaped ear plate, the connecting plate 312 is connected to one side of the ear plate by a bolt, and the positioning plate 313 is positioned against the other side of the ear plate to prevent the high-pressure box 90 from being installed out of position. The stop member 32 is fixedly arranged on the supporting plate 211 by riveting a nut, and the stop member 32 and the fixing member 31 are respectively located at both ends of the high-pressure box 90. The stop member 32 is provided with a stop plate 321 perpendicular to the supporting plate 211, and after the high-pressure box 90 is placed, the stop plate 321 abuts against the outer wall of the end of the high-pressure box 90. The stop member 32 and the fixing member 31 form a limiting at both ends of the high-pressure box 90 to fix the high-pressure box 90 on the supporting plate 211.

[0033] Several groups of brackets 20 are arranged in the height direction of the main bracket 10, and the distance between the upper and lower adjacent brackets 20 is the same or different, for accommodating the battery pack 80 or the high-pressure box 90. The bracket 20 is detachably arranged on the main bracket 10, and can be installed according to the actual transportation specifications. In this embodiment, as shown in Figure 1 , four groups of brackets 20 are arranged on the main bracket 10, which divides the main bracket 10 into four layers in space, and the topmost layer is used to place the high-pressure box 90, and the lower three layers are used to place the battery pack 80. Relatively, the height of the lower three layers is slightly lower than that of the top layer.

[0034] Further, the end of the main bracket 10 is provided with a protective net 60 to prevent the end of the main bracket 10 from being impacted by external force during the transfer process, which can cause damage to the battery pack 80 and the high-pressure box 90.

[0035] Further, the main support 10 is further provided with a handle 70, and the staff can drive the main support 10 to move the battery pack 80 by operating the handle 70.

[0036] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit them. Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
