[0019] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0020] An energy storage container according to an embodiment of the present disclosure includes:

[0021] The box body 1 comprises a base frame 2, on which at least two first guide elements 4 are provided, the first guide elements 4 extend along a first direction L1, and each first guide element 4 is arranged at intervals in a second direction L2 perpendicular to the first direction L1; and

[0022] At least one battery rack 7 is releasably fixed in the box body 1, and the battery rack 7 includes at least two columns 8 spaced apart in the second direction L2 and a crossbeam 9 connecting the upper ends of each column 8, and the lower ends of the columns 8 are respectively engaged with the first guiding elements 4 to allow each column 8 to be movable in the first direction L1 and constrained in the second direction L2.

[0023] The battery rack 7 is releasably fixed in the box body 1, that is, the battery rack 7 is detachably connected to the box body 1 or the accessories in the box body 1. In normal use, the battery rack 7 can be fixed, and when the spacing between the battery racks 7 needs to be adjusted due to the size of the battery, the connection between the battery rack 7 and the box body 1 or the accessories in the box body 1 can be released. In this way, the energy storage container disclosed in the present invention can be applicable to the installation of energy storage batteries of various sizes.

[0024] The battery rack 7 of the present disclosure is movable. The lower end of each column 8 is limited by the first guide element 4, that is, the battery rack 7 can only be pushed in the first direction L1, and when the battery rack 7 is pushed, each column 8 moves synchronously, avoiding the battery rack 7 from tilting during the pushing process.

[0025] In one embodiment, the box body 1 also includes a pair of top side beams 3 extending along the first direction L1, each top side beam 3 is provided with a second guide element 5, the second guide element 5 extends along the first direction L1, and the two ends of the cross beam 9 are respectively connected to the corresponding second guide elements 5 to limit the battery rack 7 from tipping forward and backward during movement.

[0026] Furthermore, the box body 1 further includes a pair of top side beams 3 extending along the first direction L1, each top side beam 3 is provided with a second guide element 5, the second guide element 5 extends along the first direction L1, and the second guide element 5 is configured entirely or partially below the end of the cross beam 9. The cross beam 9 extends along the second direction L2, and its two ends are respectively placed above part or all of the second guide element 5, and the second guide element 5 can guide the upper end of the battery rack 7 to move along the first direction L1 to prevent the battery rack 7 from tipping forward or backward during the process of pushing the battery rack 7. For example, the second guide element 5 can be a guide rail fixed to the side of the top side beam 3, and the guide rail can be completely located below the end of the cross beam 9 to support the cross beam 9 to prevent the battery rack from tipping forward and backward during the translation process. Of course, the second guide element 5 can also be partially located below the cross beam 9, for example, the second guide element 5 can include two guide rails, one of which is located below the cross beam 9 and the other is located above the cross beam 9, and the groove between the two straight rods accommodates the end of the cross beam 9.

[0027] After the lower end of the column 8 and the two ends of the crossbeam 9 are aligned with one end of the first guide element 4 and the second guide element 5 respectively, the battery rack 7 is pushed to enter the box body 1. After the battery rack 7 is released from fixation, the battery rack 7 can be moved forward and backward to adjust the spacing between the battery racks 7 according to the battery size.

[0028] The bottom frame 2 is provided with the same number of first guide elements 4 as the number of columns 8 of each battery rack 7. For example, if the battery rack 7 has three columns 8, then there are three first guide elements 4.

The straight rods can extend continuously in the first direction L1. The width of the limiting groove 43 is greater than the width of the lower end of the column 8, so that the column 8 can slide freely in the limiting groove 43. Optionally, a mounting plate 11 is provided at the lower end of the column 8, and the mounting plate 11 is placed in the limiting groove 43.

[0030] In one embodiment, each first guide element 4 is a raised guide rail, and the lower end of the column 8 is concave-convexly matched with the first guide element 4. The column 8 can slide on the guide rail.

[0031] In one embodiment, the column 8 is connected to the first guide element 4 through a first connector 10. Specifically, the straight rod is provided with a row of first holes arranged along the first direction L1, a portion of the first connector 10 is bolted to at least one of the first holes in the row, and another portion of the first connector 10 is bolted to the column 8. Optionally, a mounting plate 11 is provided at the lower end of the column 8, the mounting plate 11 is placed in the limiting groove 43, and the first connector 10 and the mounting plate 11 are locked by bolts.

[0032] In one embodiment, the end of the crossbeam 9 is connected to the second guide element 5 via a second connecting member 12. The second guide element 5 is provided with a row of second holes arranged along the first direction L1, a portion of the second connecting member 12 is connected to at least one of the second holes in the row by bolts, and another portion of the connecting member is connected to the crossbeam 9 by bolts.
