The fixing bracket 20 can be spaced apart along the length direction of the support bracket 50.

[0063] In some embodiments, the support bracket 50 may be longitudinally arranged. In some embodiments, the support bracket 50 may be made of sheet metal. In some embodiments, the support bracket 50 may include a support portion 51 and a first bent portion 52. The support portion 51 may be arranged parallel to the first end wall 13 and the second end wall 14, and the support portion 51 may be formed by bending a sheet metal to form a support structure with at least two support bosses. The first bent portion 52 may be located on the side of the support portion 51 facing the fixed bracket 20, and may be integrally formed with the support portion 51; specifically, it may be formed by bending the same sheet metal as the support portion 51.

[0064] In some embodiments, the support bracket 50 may further include a second bent portion 53 disposed on at least one side of the support portion 51 facing the second sidewall 12. Two second bent portions 53 may be disposed at each end of the support portion 51, and each second bent portion 53 may correspond one-to-one with a support boss. The bending direction of the second bent portion 53 may be opposite to that of the first bent portion 52; for example, the first bent portion 52 may be bent towards the second end 10b, and the second bent portion 53 may be bent towards the first end 10a. The second bent portion 53 and the support portion 51 may be integrally formed. In some embodiments, the second bent portion 53 may be connected and fixed to the second sidewall 12. Specifically, the second bent portion 53 may be disposed close to the second sidewall 12 and may be fixed to the second sidewall 12 by welding. In other embodiments, the second bent portion 53 and the second sidewall 12 may also be connected and fixed by a screw-on assembly.

[0065] In some embodiments, the supporting bracket 50 can be at least two, which can be spaced between the first end and the second end. Specifically, the supporting bracket 50 can be three, which can be spaced in parallel, and divide the inner part of the box 10 into at least four compartments 10c. In some embodiments, the structure of the three supporting brackets 50 can be the same, and the connection mode with the fixed bracket 20 can be the same. Of course, it can be understood that in other embodiments, the connection mode of at least one supporting bracket 50 with the fixed bracket 20 can also be different from the others.

[0066] In some embodiments, each supporting bracket 50 is provided with a connecting and positioning structure 60 on at least two fixed brackets 20, and each supporting bracket 50 is detachably connected with the fixed bracket 20 through the connecting and positioning structure 60. Thus, it is convenient to replace the supporting bracket 50, adjust the number and position of the supporting bracket 50, and then adapt to different energy storage modules without changing the size and weight of the energy storage box, improve the overall application range of the energy storage device, and reduce the overall manufacturing cost.

[0067] In some embodiments, the connecting and positioning structure 60 can include a connecting through hole 521 and a positioning pin 61. The connecting through hole 521 can be provided on the first bending part 52 of the supporting bracket 50, and the number of the connecting through hole 521 can be consistent with the number of the fixed bracket 20. In some embodiments, the number of the connecting through hole 521 can be two. The two connecting through holes 521 can be spaced along the length direction of the supporting bracket 50. The positioning pin 61 cooperates with the corresponding connecting through hole 521, specifically, it can be inserted from the connecting through hole 521 to fix the supporting bracket 50 on the fixed bracket 20 and locate at a set position. In some embodiments, a plurality of positioning holes 212 can be provided on the first side plate 21 of the fixed bracket 20 along the length direction of the fixed bracket 20. The positioning hole 212 can cooperate with the positioning pin 61. Specifically, the positioning pin 61 can pass through the connecting through hole 521 and be inserted into the corresponding positioning hole 212, which can be fixed by interference fit with the positioning hole 212. By positioning the supporting bracket 50 with the positioning pin 61 and different positioning holes 212, the position of the supporting bracket 50 can be adjusted.

[0068] In other embodiments, the positioning hole 212 can be omitted, and the positioning pin 61 can be directly fixed on the fixed bracket 20. The fixed bracket 20 can be spaced a plurality of positioning pins 61 along the length direction, and the positioning pin 61 can be an integral structure with the fixed bracket 20. By positioning the supporting bracket 50 with different positioning pins 61, the position of the supporting bracket 50 can also be adjusted.

At the same time, the first bending part 52 of the supporting bracket 50 is in contact with the first side plate 21 of the fixed bracket 20. In this way, the supporting bracket 50 abuts against the left fixed bracket 20, and the left fixed bracket 20 also supports and positions the supporting bracket 50. The other supporting brackets 50 and the left fixed bracket 20 and the right fixed bracket 20 are also referred to in this way. Through the cooperation of the fixed bracket 20 and the supporting bracket 50, the precise positioning between the supporting bracket 50 and the left and right fixed brackets 20 is realized, and the supporting bracket 50 can also make the left and right fixed brackets 20 and the box body 10 more firmly fixed, reduce welding, reduce positioning tooling, and reduce cost.

[0070] The second bending part 53 of the supporting bracket 50 is in welded contact with the second side wall 12. In this way, the supporting bracket 50 and the box body 10 are fixed. The other supporting brackets 50 are also referred to in this way. In this way, the gravity of the energy storage module is transmitted to the box body 10, and the left and right sides of the box body 10 are connected, increasing the strength of the box body 10. In addition, the supporting bracket 50 also fixes the fixed bracket 20 and the box body 10 more firmly, and overall guarantees the strength of the middle and lower part of the box body 10, realizes high box body strength without increasing the thickness of the sheet metal, and reduces cost.

[0071] In some embodiments, a partition 70 can be provided between the supporting bracket 50 and the second end 10b, which can divide the area between the supporting bracket 50 and the second end 10b into two compartments 10c.
