The invention relates to the technical field of automobile body structures, in particular to a battery pack bottom collision protection structure and an automobile, the battery pack bottom collision protection structure comprises a protection beam and a rotary motion mechanism, the rotary motion mechanism comprises a rotary base, a rotary part and a fixedly arranged guide seat, and the rotary base is fixedly mounted on the protection beam; the rotating base is rotationally connected with one end of the rotating piece, the protective beam rotates from a first position to a second position after being collided, and the guide seat is connected to the other end of the rotating piece; when the protective beam is at the first position, the height of the protective beam is H1; and when the protective beam is at the second position, the height of the protective beam is H2, and H2 is greater than H1. The battery pack bottom collision protection structure is a semi-active protection structure, and compared with a fixed passive protection structure, the battery pack bottom collision protection structure can passively change the posture in the collision process, and the battery pack protection effect is further improved; compared with an active protection structure, the device is free of a driving device, and the cost is greatly reduced.

    本发明涉及汽车车身结构的技术领域,具体涉及一种电池包底部碰撞防护结构以及汽车,包括防护梁和旋转运动机构,所述旋转运动机构包括旋转底座、旋转件以及固定设置的导向座,所述旋转底座固定安装于防护梁,所述旋转底座与所述旋转件的一端转动连接且所述防护梁受到碰撞后由第一位置转动至第二位置,所述导向座连接于所述旋转件的另一端;在第一位置时,防护梁的高度为H1;在第二位置时,防护梁的高度为H2,H2>H1。本发明的电池包底部碰撞防护结构为一种半主动型的防护结构:相对于固定式的被动防护结构,本发明在碰撞过程中可被动改变姿态,进一步提升电池包保护效果;相对于主动防护结构,本发明无驱动装置,成本大幅降低。
