The invention relates to the technical field of passenger car frameworks, in particular to a new energy passenger car lightweight car body framework and a welding technology thereof.The new energy passenger car lightweight car body framework comprises a plurality of side beams, an energy absorption mechanism is arranged on one sides of the side beams, the side beams are all made of aluminum alloy, and the energy absorption mechanism comprises an energy absorption box; one side of each side beam is fixedly connected with one side of the energy absorption box, an iron sheet is arranged on the other side of the energy absorption box, and a plurality of connecting assemblies are fixedly connected between the iron sheet and the energy absorption box. According to the energy absorption device, the two energy absorption mechanisms are fixed to the two sides of the vehicle body, when the side portion of the vehicle body is impacted, the energy absorption mechanisms disperse impact to the whole side portion of the vehicle body, the load capacity of a framework on the side portion of the vehicle body is improved, and a user can use the electric welding mechanism and the manufacturing mechanism to conduct automatic welding and manufacturing procedures on the energy absorption mechanisms; the use by a user is convenient.
本发明涉及客车骨架技术领域,具体涉及一种新能源客车轻量化车身骨架及其焊接工艺,包括多个侧梁,多个所述侧梁一侧设置有吸能机构,多个所述侧梁均为铝合金制造,所述吸能机构包括吸能盒,且多个侧梁一侧均与吸能盒一侧固定连接,所述吸能盒另一侧设置有铁皮,且铁皮与吸能盒之间固定连接有多个连接组件。本发明中,通过将两个吸能机构固定到车身两侧,在车身侧部遭受撞击时,吸能机构将冲击分散到整个车身侧处,提高车身侧部骨架的负荷能力,并且使用人员可用电焊机构和制造机构,对吸能机构进行自动化焊接和制造工序,便于使用人员使用。
