[0090] The two main beams 3341 are spaced apart in the longitudinal direction and are respectively fixedly connected to the columns 333 located on the same side in the longitudinal direction.

[0091] In this embodiment, the main beam 3341 is a bent part. This design can reduce the weight of the bottom frame 332 while ensuring the strength of the bottom frame 332, thereby reducing the weight of the entire battery cluster frame 3 and even the entire mobile energy storage container to reduce costs.

[0092] Specifically, the main beam 3341 includes a connecting portion and a main body portion protruding from the connecting portion in the longitudinal direction. The connecting portion is fixedly connected to the column 333. The main body portion is located on a side of the connecting portion away from the column 333 in the longitudinal direction.

The support beams 3342 extend in the longitudinal direction, and both ends of the longitudinal direction of each support beam 3342 are fixedly connected to the bottom of the two main beams 3341 in a one-to-one correspondence.

[0094] In this embodiment, the support beams 3342 are arranged one by one with the columns 333 in each column 333 group. In addition, the longitudinal ends of the support beams 3342 are fixedly connected with the columns 333, which can effectively enhance the strength and stability of the mounting frame 33.

[0095] In this embodiment, the support beam 3342 is fixedly connected to the column 333 by bolts and nuts. At this time, the opening design on the column 333 is convenient for performing rivet nut operation inside it, so as to facilitate the bolt and nut connection and fixation of the support beam 3342 and the column 333.

Specifically, multiple mounting racks 33 are distributed in two rows and multiple columns. The two rows of mounting racks 33 are distributed in a lateral interval. In each row of mounting racks 33, the longitudinal ends of two adjacent mounting racks 33 are fixedly connected.

[0098] In this embodiment, in each row of mounting frames 33, the adjacent ends of two adjacent mounting frames 33 share the same set of columns 333, the same first top beam 3311 and the first bottom beam 3321. This design can reduce the weight of the entire battery cluster frame 3 and reduce the cost while ensuring the strength of the entire battery cluster frame 3.

[0099] Continue to refer Figure 1 to Figure 3 The reinforcing component 32 is arranged on the frame body 31 , which can improve the strength and stability of the entire battery cluster frame 3 and facilitate the hoisting of the entire battery cluster frame 3 .

[0100] The reinforcement assembly 32 includes a plurality of support members and a plurality of longitudinal beams 322 .

[0101] A plurality of groups of support members are erected at intervals in the horizontal direction on the top of the frame body 31, and the support members include a plurality of support columns 3211 arranged at intervals in the longitudinal direction. Specifically, a support column 3211 is erected at each corner of the mounting frame 33, respectively.

[0102] In this embodiment, the tops of the adjacent ends of two adjacent rows of mounting frames 33 are fixedly connected to the bottom of a group of supporting members at the same time. In each row of mounting frames 33, the tops of the adjacent ends of two adjacent mounting frames 33 are fixedly connected to the bottom of a support column 3211 at the same time. This design can reduce the weight of the entire battery cluster frame 3 and reduce costs while ensuring the connection strength between the support column 3211 and the frame body 31.

[0103] In this embodiment, the support column 3211 is a bent piece with a U-shaped cross section to reduce its weight, thereby reducing the weight of the entire battery cluster frame 3 and reducing costs.

[0104] Multiple longitudinal beams 322 are arranged in one-to-one correspondence with multiple groups of support members. The longitudinal beams 322 extend longitudinally and are arranged on the top of multiple support columns 3211, and are used to be directly or indirectly connected to the top plate 111 of the mobile energy storage container. At this time, the frame body 31 is connected to the top plate 111 as a whole through the support columns 3211 and the longitudinal beams 322, which can increase the stability of the entire battery cluster frame 3, prevent the battery cluster frame 3 from shaking when the entire mobile energy storage container moves, and also increase the stability of the entire mobile energy storage container.
