[0069] In an exemplary embodiment of the present application, the battery frame 20 includes a first outer frame 21 and a first tie rod 22. The first outer frame 21 is a hollow structure having a first connecting portion and a second connecting portion, the first connecting portion and the second connecting portion being arranged diagonally opposite each other, and the first tie rod 22 being connected between the first connecting portion and the second connecting portion.
