According to one embodiment of the present utility model, the at least one first side plate 112 is formed with a protection beam 12 at a side facing away from the battery receiving chamber, and the protection beam 12 is disposed at an edge of the first side plate 112 near the bottom plate 111 side. Since the protection beams 12 are members for protecting the battery and the frame assembly 1, the arrangement of the protection beams 12 affects the protection effect of the frame assembly 1 on the battery.

According to one embodiment of the present utility model, the distance between the inner guard beam 13 and the adjacent first side plate 112 is d and satisfies: d is more than or equal to 20mm and less than or equal to 70mm. Since the inner shielding beam 13 is spaced apart from the first side plate 112, the spacing between the inner shielding beam 13 and the first side plate 112 may affect the protection of the frame assembly 1 from the battery. Specifically, the distance between the inner guard beam 13 and the first side plate 112 may be denoted by d, and d is required to satisfy: the design that d is less than or equal to 20mm and less than or equal to 70mm and d is less than or equal to 70mm can enable the reserved space of the battery accommodating cavity for accommodating the battery to meet the battery assembly requirement, and the design that d is more than or equal to 20mm can ensure that enough collision buffer space is reserved between the inner protection beam 13 and the first side plate 112.
