The invention discloses a foamed aluminum composite plate, a tailor-welding method, a vehicle chassis and a vehicle. The foamed aluminum composite plate comprises a panel, a back plate and a foamed aluminum layer. The panel is provided with a first welding seam, and the back plate is provided with a second welding seam; the foamed aluminum layer is clamped between the panel and the back plate, the foamed aluminum layer comprises a plurality of sub-aluminum layer parts, and a splicing seam is formed between every two adjacent sub-aluminum layer parts; and at least one of the first welding seam and the second welding seam and the splicing seam are arranged in a staggered mode in the thickness direction. The foamed aluminum composite plate is formed by splicing and welding a plurality of sub composite plates in a staggered manner, so that continuous transmission of force at a welding seam is avoided, and the foamed aluminum composite plate has better capabilities of absorbing detonation energy and attenuating detonation shock waves.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to an aluminum foam composite board, a tailor welding method, a vehicle chassis and a vehicle. Background technique [0002] In the prior art, the foamed aluminum composite board welded by the traditional tailor-welding method will produce continuous welds along the thickness direction, which will affect the ability of the foamed aluminum composite board to absorb detonation energy and attenuate detonation shock waves , leading to a decrease in the explosion-proof performance of the vehicle chassis, which in turn leads to a decrease in the safety of the vehicle, and there is room for improvement. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. For this reason, the present invention proposes an aluminum foam composite board, which is formed by dislocation welding of...
