Aluminum foam composite panels, tailor welding method, and vehicle chassis and vehicles

Abstract

The invention discloses a foamed aluminum composite board, a tailor welding method, a vehicle chassis and a vehicle, wherein the foamed aluminum composite board comprises: a panel, a back board and a foamed aluminum layer. There is a first weld seam on the panel, and a second weld seam on the back plate; the foamed aluminum layer is sandwiched between the face plate and the back plate, and the foamed aluminum layer includes: a plurality of sub-aluminum In the layer part, there is a splicing seam between two adjacent sub-aluminum layer parts; wherein, at least one of the first welding seam and the second welding seam is staggered from the splicing seam along the thickness direction. The aluminum foam composite panel is made of dislocation and tailor-welded multiple sub-composite panels, which avoids the continuous transmission of force at the weld, and has better ability to absorb detonation energy and attenuate detonation shock waves.

Description

Foam aluminum composite panel, tailor welding method, and vehicle chassis and vehicle technical field The present invention relates to the technical field of vehicles, in particular, to a foamed aluminum composite panel, a tailor welding method and a vehicle Chassis and Vehicle. Background technique In the prior art, the foamed aluminum composite board welded by the tailor welding method of traditional foamed aluminum composite board can produce The continuous welding seam along the thickness direction will affect the ability of the foamed aluminum composite panel to absorb detonation energy and attenuate the detonation shock wave. As a result, the explosion-proof performance of the vehicle chassis is reduced, which in turn leads to a reduction in the safety of the vehicle, and there is room for improvement. SUMMARY 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...

AI Technical Summary

Problems solved by technology

[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
