Abstract

The invention relates to the field of aluminum products, and particularly relates to an aluminum alloy section for a new energy automobile framework, which comprises an outer frame in a square structure, a middle frame and an inner frame. The outer frame is provided with a top edge, a bottom edge and two side edges. The middle frame comprises a group of closed opposite angles and a group of open opposite angles; the outer frame extends inwards from the middle parts of the two side edges to form connecting edges to be connected with the closed opposite angles of the middle frame; an inwards concave embedding groove is formed in the middle part of each side of the middle frame; the inner frame is integrally embedded in the embedding grooves in the edges of the middle frame; the inner frame comprises a set of straight line opposite edges and a set of broken line opposite edges, the middles of the straight line opposite edges extend towards the center to form straight section edges, bearing arcs are installed at the ends of the straight section edges, and a supporting rod is embedded in the two bearing arcs. The aluminum alloy section is applied to automobile framework production.

Description

technical field [0001] The invention relates to the field of aluminum products, in particular to an aluminum alloy profile for a new energy vehicle frame. Background technique [0002] The weight of the new energy vehicle battery pack accounts for about 30%-40% of the vehicle. Therefore, electric vehicles must adopt more advanced methods and measures than conventional lightweight technologies while being electrified. Aluminum alloys, magnesium alloys, titanium alloys, plastics and composite materials, fine ceramics, metal matrix composites, and non-metal matrix composites have accelerated application demands. At present, some electric vehicles have gradually begun to use aluminum alloy profiles to form body frames. [0003] As shown in CN108340970A, an aluminum alloy profile for a new energy vehicle frame includes a first energy-absorbing area made of a first material and a second energy-absorbing area made of a second material different from the first material. An energy-...
