The invention provides a pre-tightening force limiting mechanism and a vehicle safety device. The pre-tightening force limiting mechanism comprises a pipe body; the pre-tightening assembly is arranged in the pipe body and comprises a moving part suitable for reciprocating motion in the pipe body and a force transmission part; the force limiting assembly is arranged in the pipe body and comprises a force limiting piece which moves in cooperation with the pre-tightening assembly. The pre-tightening force limiting mechanism is configured to be capable of being switched between a pre-tightening state and a force limiting state, in the pre-tightening state, the moving part is driven and drives the power transmission part to move in the first direction to achieve pre-tightening, and in the force limiting state, the moving part is driven by the force transmission part to move in the second direction opposite to the first direction, and force limiting is achieved through the force limiting part. According to the pre-tightening force limiting mechanism, a two-way restraining structure integrating the pre-tightening function and the force limiting function is provided, force acting on a driver and passengers is relieved, harm to the human body is reduced, the overall structure is compact, manufacturing is easy, and the magnitude of load or force limiting resistance can be preset according to different crashworthiness.

    本公开提供一种预紧限力机构及车辆安全装置。预紧限力机构包括:管体;预紧组件,预紧组件装设于管体内,并包括适于在管体内往复移动的运动件以及力传递件;限力组件,限力组件装设于管体内,并包括与预紧组件协同运动的限力件。预紧限力机构配置为能够在预紧状态和限力状态之间切换,在预紧状态,运动件被驱动并带动力传递件沿第一方向移动实现预紧,在限力状态,运动件由力传递件驱动以沿相反于第一方向的第二方向移动并通过限力件实现限力。本公开的预紧限力机构提供了一种集成预紧功能和限力功能的双向约束结构,缓解作用于驾乘人员身上的力,减小对人体的伤害,整体结构紧凑且制造简单,能够根据不同的耐撞性预设负载或限力的阻力大小。
