The invention discloses an anti-collision vehicle frame and a vehicle, the anti-collision vehicle frame comprises a longitudinal beam, the longitudinal beam is provided with a main cavity and a plurality of auxiliary cavities, each auxiliary cavity is provided with a liquid passing hole, any two adjacent auxiliary cavities are communicated through the liquid passing hole, the auxiliary cavity close to the main cavity is communicated with the main cavity through the liquid passing hole, the longitudinal beam is provided with a side wall cavity, and the side wall cavity is communicated with the auxiliary cavities; the anti-collision beam is movably arranged in the main cavity in the length direction of the longitudinal beam, the anti-collision beam is provided with a liquid storage cavity, the liquid storage cavity is provided with a liquid outlet hole, the liquid storage cavity is communicated with the main cavity through the liquid outlet hole, the side wall cavity is communicated with the liquid storage cavity, and a cavity jointly defined by the anti-collision beam and the main cavity is internally provided with a buffer solution. According to the anti-collision beam, collision energy generated when the anti-collision beam is collided can be absorbed and attenuated by the buffer solution, the collision energy is absorbed and attenuated multiple times, the anti-collision effect is remarkably enhanced, and the deformation degree of the anti-collision beam is reduced.
本发明公开了一种防撞车架及车辆,防撞车架包括:纵梁,纵梁具有主腔室和多个副腔室,每个副腔室具有过液孔,任意相邻的两个副腔室通过过液孔连通,靠近主腔室的副腔室通过过液孔连通主腔室,纵梁具有侧壁腔,侧壁腔连通副腔室;防撞梁,防撞梁沿纵梁的长度方向可移动地设在主腔室内,防撞梁具有储液腔,储液腔具有出液孔,储液腔通过出液孔连通主腔室,侧壁腔连通储液腔,防撞梁与主腔室共同限定的空腔内设有缓冲液。本发明能将防撞梁在受到撞击时的撞击能量被缓冲液吸收和衰减,并对撞击能量进行多次吸收和衰减,显著增强防撞效果,减小防撞梁的变形程度。
