The invention discloses an integrated impact-resistant front anti-collision beam of an automobile. The anti-collision beam comprises an arched front beam, buffering energy absorption boxes, inner enhanced anti-collision columns, thickened L-shaped connecting plates, a small folding clamping plate and an upper connecting plate. Arc-shaped thickening curved surfaces are arranged above and below theinner side of the arched front beam. The bottoms of the buffering energy absorption boxes are welded and fixed on the left and right inner sides of the arched front beam. The inner reinforced anti-collision columns are fixed to the bottoms of the inner sides of the buffering energy absorption boxes, and the bottoms of the inner reinforced anti-collision columns and the inner side of the arched front beam are connected into a whole. The thickened L-shaped connecting plates and the upper tops of the buffering energy absorption boxes are welded into a whole. The upper connecting plate and the small folding clamping plate are welded and fixed to the outer sides of the upper side face and the lower side face of the arched front beam. The anti-collision beam is an integrated connecting mechanism, multiple fixed connections by bolts are omitted, it is guaranteed that the inner side of the arch-shaped front beam only sinks inwards and cannot be broken during collision, and it is guaranteed that the overall anti-collision performance is excellent.
本发明公开一种汽车连体式耐冲击前防撞梁,包括拱形前梁、缓冲吸能盒件、内增强抗撞柱、增厚L形连接板、小折卡板和上连板,拱形前梁的内侧上下方有弧形增厚曲面,缓冲吸能盒件底部焊接固定在拱形前梁左右内侧,内增强抗撞柱固定在缓冲吸能盒件内侧底部,内增强抗撞柱的底部与拱形前梁内侧连为一体,增厚L形连接板与缓冲吸能盒件的上顶部焊接连为一体,上连板和小折卡板分别焊接固定在拱形前梁的上下侧面外侧。本发明为整合连接一体式机构,取消了多处螺栓固定连接,确保碰撞时拱形前梁内侧只会内陷不会断裂,确保本发明整体抗碰撞性能优良。
