Abstract

The invention discloses a rolled section bar and a preparation method thereof, a battery pack skeleton, and a battery pack. The rolled section bar comprises a rolled section bar body prepared by multiple times of rolling and bending of a steel belt, and the rolled section bar body comprises a first part, a second part and a reinforcing rib; the middle reinforcing rib enables the rolled section barto be effectively further thinned and lightened under the condition that the strength and rigidity are not reduced, a battery pack skeleton can be defined by the roller section bar, and an L-shaped pipe structure defined by the second component and the reinforcing rib can achieve the bottom supporting function on a battery pack; meanwhile, the manufacturing process is integrated on line, continuous production is achieved, the welding difficulty of conventional production of complex rolling closed profile products is overcome, the defects of low efficiency, high cost and the like are overcome,and the manufacturability of the products is met.

Description

technical field [0001] The invention relates to the technical field of fixed battery devices, in particular to a rolling profile and a preparation method thereof, a battery pack frame and a battery pack. Background technique [0002] For a long time, the profile structure used in the battery pack of traditional new energy electric vehicles is basically made of aluminum profiles, mainly because aluminum profiles have low density and light weight, which can realize the lightweight of new energy electric vehicles and improve the cruising range . In addition, since the battery pack is a safety component, it is mainly responsible for the safety protection of the battery pack, and its anti-puncture and anti-collision performance is a key factor. The inventor found that the battery pack made of aluminum profiles has risks in terms of safety, and the battery is easy to catch fire after a collision, which will reduce the safety of new energy electric vehicles. The battery pack made...
