The invention discloses a front longitudinal beam and front anti-collision beam connecting structure which is characterized in that offset collision guide blocks are arranged at the two ends of a front anti-collision beam, a guide supporting surface is arranged on the outer side of the front end of each front longitudinal beam, and the inner side surface of each offset collision guide block is a guide block inclined surface. When a vehicle is subjected to offset collision, under the action of a collision object, the end part of the front anti-collision beam deforms backwards approximately by taking the front end mounting center of the energy absorption box as a central point, the offset collision guide block can hit the guide supporting surface, and the inclined surface of the guide block is attached to the guide supporting surface, so that a transverse force or a lateral force or a Y-direction force is applied to the front longitudinal beam; the whole vehicle body is promoted to move in the stress direction and leave the collision object, the time of hard collision between the vehicle body and the collision object is shortened, large-angle drifting caused by hard collision can be effectively avoided, a driver can maintain the basic driving direction, and the offset collision performance and the driving safety of the vehicle are improved.
本发明公开了一种前纵梁与前防撞梁连接结构,在前防撞梁的两端配置有偏置碰撞导向块,在每根前纵梁的前端的外侧具有导向支撑面,偏置碰撞导向块的内侧表面为导向块斜面。当车辆发生偏置碰撞时,在碰撞物的作用下,前防撞梁的端部发生变形,大致以吸能盒的前端安装中心为中心点向后发生变形,偏置碰撞导向块会砸向导向支撑面,导向块斜面贴在导向支撑面上,从而给前纵梁以横向力或侧向力或Y向力,促使车身整体沿着受力方向移动,离开碰撞物,减少了车身与碰撞物硬性碰撞的时间,可有效避免因硬性碰撞而出现大角度甩尾,利于驾驶员维持基本的驾驶方向,提升了偏置碰撞性能和车辆的驾驶安全性。
