The invention relates to the technical field of vehicle front protection, and discloses a protection device used after collision of pedestrian in front of a vehicle; the device comprises a machine shell, an air storage box is fixedly connected in the machine shell, a piston plate is slidably connected in the air storage box, one side of the air storage box penetrates through the side wall of the machine shell, and movable holes are symmetrically formed in the side wall of the air storage box; springs are symmetrically and fixedly connected to the side walls, close to the movable holes, of the piston plates, the other ends of the two springs are fixedly connected to the inner side wall of the machine shell, movable rods are slidably connected into the two movable holes correspondingly, and the ends, on the same side, of the two movable rods penetrate through the corresponding springs and the movable holes, extend outwards and are jointly and fixedly connected with a baffle. A buffering air bag can be automatically opened after a pedestrian is collided, the pedestrian can be effectively protected, secondary collision in front of a vehicle after the pedestrian topples over is avoided as much as possible, and damage to the body of the pedestrian is reduced.

    本发明涉及车前防护技术领域,且公开了一种车前行人碰撞后的防护装置,包括机壳,所述机壳内固定连接有储气箱,所述储气箱内滑动连接有活塞板,所述储气箱的一侧贯穿机壳侧壁,且其侧壁上对称开设有活动孔,所述活塞板靠近活动孔的侧壁上对称固定连接有弹簧,两个所述弹簧的另一端固定连接在机壳内侧壁上,两个所述活动孔内均滑动连接有活动杆,两个所述活动杆的同侧端穿过对应的弹簧和活动孔并向外延伸,且共同固定连接有挡板。本发明可以在行人碰撞后自动将缓冲气囊打开,能够对行人进行有效的保护,尽量避免行人倾倒后易于车前发生二次碰撞,减小对行人身体损害。
