The invention relates to a zero-gravity seat energy-absorbing and supporting mechanism based on passenger protection, which comprises a seat cushion framework and a seat cushion locking mechanism mounted on the seat cushion framework, the seat cushion locking mechanism comprises an unlocking bracket, a rotating bracket, a cam locking piece for driving the rotating bracket to be separated from the unlocking bracket, an exploder for driving the cam locking piece to rotate and unlock, a pull wire for connecting the exploder with the cam locking piece, and a telescopic damping rod which is arranged between the seat cushion framework and the seat basin and is used for absorbing energy; one end of the telescopic damping rod is hinged to the seat basin, the other end of the telescopic damping rod is hinged to the seat cushion framework, when the seat basin is subjected to zero-gravity posture adjustment on the seat cushion framework, the telescopic damping rod overcomes damping force to stretch upwards, and when the seat basin is driven by the seat cushion locking mechanism to rapidly return, the telescopic damping rod overcomes the damping force to absorb energy and retracts to the initial position; the automobile seat cushion has the advantages that energy is absorbed after high-speed collision through the telescopic damping rods, the seat cushion can return quickly, energy is absorbed, and harm to passengers is reduced.

    本发明涉及一种基于乘员防护的零重力座椅吸能及支撑机构,包括:坐垫骨架、安装在坐垫骨架上的坐垫锁止机构,坐垫锁止机构包括:解锁支架、转动支架、驱动转动支架与解锁支架分离的凸轮锁止片、驱动凸轮锁止片转动解锁的点爆器、连接点爆器与凸轮锁止片的拉线、安装在坐垫骨架与坐盆之间用于吸能的伸缩阻尼杆,伸缩阻尼杆的一端铰接在坐盆上,另一端铰接在坐垫骨架上,坐盆在坐垫骨架上进行零重力姿态调节时,伸缩阻尼杆克服阻尼力向上拉伸,坐盆在坐垫锁止机构的带动下快速回位时,伸缩阻尼杆克服阻尼力进行吸能并缩回初始位置;本发明的优点:通过伸缩阻尼杆高速碰撞后进行吸能,实现坐垫位置快速回位及能量吸收,对乘员起到降低伤害作用。
