The invention relates to the field of truck safety and particularly relates to an automobile protective guard. The automobile protective guard comprises a cross rod, wherein an impact facing surface protrudes outwards from a breadth surface of the cross rod, and the impact facing surface is parallel to the breadth surface. The automobile protective guard is advantaged in that cross bars of the protective guard are designed into structures with outwards convex breadth surfaces, an outwards-protruding part is parallel to the breadth surface and is arranged to be the impact facing surface, a transverse rod of the outwards-protruding structure enables the overall rigidity of the protective guard to be enhanced, when an automobile collides with the transverse rod of the protective guard, the outwards-protruding impact facing surface can locally deform to effectively absorb collision kinetic energy, so the deformation quantity of the transverse rod caused by collision is small.

    本发明涉及载货汽车安全领域,具体地涉及一种车辆防护栏。所述车辆防护栏包括横杆,自所述横杆的幅宽面向外凸出有一迎撞面,且所述迎撞面与所述幅宽面平行。本发明中将防护栏的横杆设计为由幅宽面外凸的结构,外凸的部分与该幅宽面平行并被设置为迎撞面,该外凸结构的横杆使防护栏的整体刚度增强,并且,当车辆与该防护栏的横杆发生碰撞时,外凸的迎撞面可局部变形以有效吸收碰撞动能,使碰撞造成的横杆形变量小。
