The invention belongs to the technical field of automobile safety, and particularly relates to a linear rotation compression energy absorption automobile anti-collision protection mechanism which comprises a main beam and a linear rotation compression energy absorption device connected to the main beam. The linear rotating compression energy absorption device comprises an energy absorption box body, a base, a detachable combined lead screw, a touch pressing piece, a rotating scraper and an internally-attached comprehensive energy absorption sleeve piece, the base is arranged at the bottom of the energy absorption box body, and the detachable combined lead screw is vertically installed in the middle of the top of the base. A traditional energy absorption box wrinkle deformation crumple energy absorption structure is optimized into a linear rotating compression energy absorption structure which takes wrinkle deformation energy absorption as an auxiliary mode and provides energy generated by longitudinal compression for rotating mechanical power, and longitudinal compression energy is transversely transferred through rotating mechanical power spiral rotating compression. Compared with an existing energy absorption box, the collision energy absorption amount and absorption efficiency of the energy absorption box are improved to a great extent, and the personal safety and the automobile body safety are better guaranteed.

    本发明属于汽车安全技术领域,尤其为一种直线旋转压缩吸能汽车防碰撞保护机构,包括主梁以及连接于主梁上的直线旋转压缩吸能装置,所述直线旋转压缩吸能装置包括吸能盒体、底座、可拆分组合丝杠、触压件、旋转刮刀和内附综合吸能套件,所述底座设置于吸能盒体的底部,所述可拆分组合丝杠垂直安装于底座的顶部中间位置。本发明将传统的吸能盒褶皱变形溃缩吸能结构优化为以褶皱变形吸能为辅,以将纵向压缩产生的能量提供旋转机械动力的方式,通过旋转机械动力螺旋旋转压缩将纵向压缩能量进行横向转移为主的直线旋转压缩吸能结构,较之现有的吸能盒在极大程度上提高了其碰撞能量吸收量以及吸收效率,更好的保障了人身及车身安全。
