The invention relates to an anti-collision beam structure for improving the front collision compatibility and the small offset collision safety of a vehicle, which comprises a cross beam and an energyabsorption box assembly, and the energy absorption box assembly comprises a left side energy absorption box main body and a right side energy absorption box main body; one part of the left side energy absorption box main bodies are covered with left side energy absorption box covering parts, and part of the right side energy absorption box main bodies are covered with right side energy absorptionbox covering parts; the left side energy absorption box main body is connected with the cross beam through a bolt, and the right side energy absorption box main body is connected with the cross beamthrough a bolt; the cross beam comprises a plurality of sections of arc structures; wherein the energy absorption box main body comprises a mounting bottom plate, and a crumple guide rib and a cross beam end part reinforcing structure are fixed on the mounting bottom plate; one side of the crumple guide rib is connected with an inclined face, and the crumple guide rib and the inclined face are connected with an upper connecting face. According to the novel aluminum alloy variable cross-section cross beam structure and the machining method, the high bending resistance of the cross beam can be guaranteed, and meanwhile the modeling and mounting requirements of an automobile outside the cross beam are met; The machining method is high in applicability.

    本发明涉及提高车辆正面碰撞兼容性和小偏置碰撞安全性防撞梁结构,包括横梁和吸能盒总成,所述吸能盒总成包括左侧吸能盒主体和右侧吸能盒主体;部分左侧吸能盒主体上覆盖有左侧吸能盒覆盖件,部分右侧吸能盒主体覆盖有右侧吸能盒覆盖件;所述左侧吸能盒主体与横梁通过螺栓相连接,所述右侧吸能盒主体与横梁通过螺栓相连接;所述横梁包括多段弧结构;所述吸能盒主体包括安装底板,安装底板上固定有溃缩引导筋和横梁端部加强结构;溃缩引导筋的一侧连接有斜面,溃缩引导筋和斜面连接有上连接面。本发明通过新型的铝合金变截面横梁结构和加工方法,能够实现既保证横梁高抗弯性的同时,又保证了横梁外部汽车的造型及安装需求;加工方法适用性强。
