The invention relates to the technical field of automobile protection accessory devices, in particular to an automobile collision buffering and energy-absorbing device which can limit a buffering column after a first spring is compressed to a certain compression amount so as to prevent the first spring from driving a front bumper to rebound. The device comprises a fixed seat, a buffer column, a first spring, a first mounting plate and a second mounting plate, and a buffer groove is formed in the center of the left side wall of the fixed seat; the device further comprises a second upper spring,a second lower spring, an upper clamping plate, a lower clamping plate, an upper pull rope, a lower pull rope, an upper pull ring and a lower pull ring, an upper clamping groove and a lower clampinggroove are formed in the right half areas of the top end and the bottom end of the buffer column correspondingly, and an upper sliding groove and a lower sliding groove are formed in the right half areas of the inner top side wall and the inner bottom side wall of the buffer groove correspondingly. An upper through hole and a lower through hole are longitudinally formed in the right half areas ofthe top end and the bottom end of the fixed seat correspondingly.

    本发明涉及汽车防护附属装置的技术领域,特别是涉及一种汽车碰撞缓冲吸能装置,可在将第一弹簧压缩到一定的压缩量之后对缓冲柱进行限位,防止第一弹簧带动前保险杠出现回弹;包括固定座、缓冲柱、第一弹簧、第一安装板和第二安装板,固定座左侧壁中央区域设置有缓冲槽;还包括第二上弹簧、第二下弹簧、上卡位板、下卡位板、上拉绳、下拉绳、上拉环和下拉环,缓冲柱顶端和底端右半区域分别设置有上卡位槽和下卡位槽,缓冲槽内顶侧壁和内底侧壁右半区域分别设置有上滑动槽和下滑动槽,固定座顶端和底端右半区域分别纵向设置有上贯通孔和下贯通孔。
