The invention discloses a protection device for a driver during emergency braking of an automobile, and belongs to the technical field of automobile safety. The protection device comprises a half-frame base, two sets of C-shaped steel, two sets of left welding blocks, two sets of right welding blocks and two sets of lifting hydraulic rods. Openings of the two sets of C-shaped steel are oppositelyand horizontally fixed to the front side and the rear side of a top opening of the semi-frame base; the two sets of left welding blocks are welded to the left ends of inner cavities of the two sets ofC-shaped steel correspondingly. A forward and reverse motor rotates backwards such that a nut of a ball screw moves leftwards; meanwhile, when the inertia force is small, a first telescopic spring isused for buffering the seat; a speed increasing device can provide three ball screw rotating speeds; within the same time, the nut moving distances of the ball screws are different, then the compression amount of a second telescopic spring is changed, the reverse acting force is rapidly increased, speed reduction is facilitated. The device is automatically and manually combined, operation is convenient, a driver and passengers are protected in the speed reduction process, and safety is high.

    本发明公开了汽车安全技术领域的一种用于驾驶员在汽车急刹时的保护装置,包括半框基座、两组C型钢、两组左焊块、两组右焊块和两组升降液压杆,两组所述C型钢开口相对水平固定在半框基座顶部开口前后两侧,两组所述左焊块分别焊接在两组所述C型钢的内腔左端,正反转电机反转,使滚珠丝杠的螺母向左移动,同时在惯性力较小时,利用第一伸缩弹簧进行座椅缓冲,增速装置可以提供三种滚珠丝杠转速,在相同时间内,滚珠丝杠的螺母移动距离不同,进而改变第二伸缩弹簧的压缩量,快速增大反向作用力,便于减速,该装置自动和手动向结合,操作方便,在减速过程中对驾驶员和乘客进行保护,安全性强。
