In some embodiments of the present invention, as shown in fig. 1 and 3, the first connecting portion 200 further includes a fixing portion 230, and the supporting plate 210 extends in a direction away from the connecting plate 220. Here, it is also understood that the supporting plate 210 extends away from the first flange 140 to ensure that the supporting plate 210 can extend toward the lower case 2100 of the battery pack 2000, so as to facilitate the subsequent connection of the mounting bracket 1000 to the lower case 2100 through the first connecting part 200.
