The invention belongs to the technical field of automobile accessories, and particularly relates to an automobile anti-collision beam which comprises a main beam, an energy absorption component and a frame connecting piece. The side wall of the energy absorption component is arranged to be of a corrugated structure, so that when a vehicle collides with the energy absorption component and is subjected to front impact, impact force parallel to the axial direction of the energy absorption component cannot be kept parallel to the side wall of the energy absorption component, force borne by the face, not parallel to the axis, of the side wall of the energy absorption component and the face form a certain included angle, force borne by the side wall of the energy absorption component has component force in the direction perpendicular to the side wall, then the local side wall bears radial force, the energy absorption component can easily and evenly deform, and in the whole process, the energy absorption component always absorbs impact energy through deformation till the maximum deformation amount is achieved. Therefore, it is guaranteed that the energy absorption component can stably and reliably absorb impact energy, impact on a driver is reduced, and the safety of the driver and passengers is guaranteed.
本发明属于汽车配件技术领域,具体的说是一种汽车防撞梁,包括主梁、吸能部件和车架连接件;本发明中通过将吸能部件的侧壁设置成波纹状结构,进而车辆撞击吸能部件受到正面冲击时,平行于吸能部件轴向的冲击力,并不能与吸能部件的侧壁保持平行,吸能部件的侧壁不与轴线平行的面上受到的力与该面呈一定的夹角,进而使得吸能部件的侧壁上受到的力在垂直与侧壁的方向有分力,进而使得局部的侧壁受到径向的力,使吸能部件能够较容易且均匀的变形,且在整个过程中吸能部件始终通过变形吸收冲击的能量直至达到最大变形量,进而保证了吸能部件能够稳定可靠的吸收冲击的能量,进而减少了驾车人员受到的冲击,进而保证了驾乘人员的安全。
