The invention discloses a net-structure installation assembly. The net-structure installation assembly comprises a battery box body, a battery module and a net-shaped buffer assembly, wherein the battery module and the net-shaped buffer assembly are arranged in the battery box body, the net-shaped buffer assembly comprises a plurality of first buffer horizontal rods, a plurality of second buffer vertical rods, a first buffer semi-sphere and a second buffer semi-sphere, the first buffer horizontal rods and the second buffer vertical rods are arranged perpendicular to each other, the first buffer horizontal rods and the second buffer vertical rods form a net-shaped structure, and the first buffer semi-sphere and the second semi-sphere are correspondingly arranged at connection nodes of the first buffer horizontal rods and the second buffer horizontal rods. In the net-structure installation assembly, the plurality of first buffer horizontal rods, the plurality of second buffer vertical rods, the first buffer semi-sphere and the second buffer semi-sphere are arranged in the net-shaped buffer assembly and form the net-shaped structure, so that an elastic buffer effect can be achieved during the transportation process of the battery box body, the safety of the battery box body can be improved, and the battery is prevented from being damaged.
