The invention provides an automobile front end structure and an automobile, and relates to the technical field of automobile manufacturing, the automobile front end structure comprises a front end upper cross beam, a front shock absorption tower assembly and a bridging pipe beam, the two ends of the front end upper cross beam are provided with extension legs bent towards the rear portion of the automobile, and the front shock absorption tower assembly and the extension legs are correspondingly arranged; the end, close to the front shock absorption tower assembly, of each extension leg is connected with one position of the front shock absorption tower assembly, and the end, away from the front shock absorption tower assembly, of each extension leg is connected with the other position of the front shock absorption tower assembly through the corresponding bridging pipe beam. The extending legs which are bent and extend backwards are formed at the two ends of the front-end upper cross beam, and the extending legs, the bridging pipe beam and the front shock absorption tower assembly are connected end to end, so that closed triangular structures are formed on the left side and the right side of the front-end upper cross beam in a surrounding mode correspondingly; in addition, two force transmission paths of the extension legs and the bridging pipe beams are added, so that strength damage caused by stress concentration is avoided.
本发明提供了一种汽车前端结构及汽车,涉及汽车制造技术领域,所述汽车前端结构包括前端上横梁、前减震塔总成及桥接管梁,前端上横梁的两端设有向汽车后方弯曲的延伸腿,前减震塔总成与延伸腿对应设置,延伸腿靠近前减震塔总成的一端与前减震塔总成的一处连接,延伸腿远离前减震塔总成的一端通过对应的桥接管梁与前减震塔总成的另一处连接。本发明通过在前端上横梁的两端形成向后弯曲延伸的延伸腿,延伸腿、桥接管梁及前减震塔总成三者首尾连接,以在前端上横梁的左右两侧分别围成封闭的三角形结构,车辆前端在受载时,在原先通过纵梁向汽车后方传力的基础上,另外增加延伸腿、桥接管梁这两条传力路径,避免应力集中发生强度破坏。
