Lead screw driving and passive terminal locking device for sliding plug door
The invention provides a sliding plug door lead screw driving and passive terminal locking device which comprises a lead screw, a lock box and a lead screw nut assembly, the lead screw nut assembly comprises a roller, a swing arm set, a swing arm, a base, a limiting shaft, a limiting plate, a torsion spring, a roller seat and a lead screw nut, the swing arm set is a rigid swing arm body, and the swing arm set is a rigid swing arm body. The base is hinged to the swing arms, the idler wheel and the limiting plate are fixed to the idler wheel base, the idler wheel base is fixed to the lead screw nut and does not move relatively, the lead screw nut is sleeved with the torsion spring, one end of the torsion spring is limited to the idler wheel base, the other end of the torsion spring is limited to the swing arm set, and the limiting shaft is rotationally connected with the swing arms and penetrates through the limiting plate. After the door is closed, the position of the lead screw nut is limited instead of directly limiting the lead screw, the terminal locking mode can reduce the influence of vibration impact on the lead screw, and safety and reliability are improved; the movement characteristic that a sliding plug door is plugged out and plugged in is utilized, a related constraint track is set on the limiting plate, through movement deviation and track constraint, rotation of a lead screw nut around a shaft when the lead screw nut moves back and forth in the axial direction of a lead screw is limited, and a full-length locking guide rail which is generally necessary for terminal locking is omitted.
本发明提供一种塞拉门丝杆驱动、无源终端锁闭装置，包括丝杆、锁盒以及丝杆螺母组件，所述丝杆螺母组件包括滚轮、摆臂组、摆臂、底座、限位轴、限位板、扭簧、滚轮座以及丝杆螺母，其中，所述摆臂组为刚性摆臂体，对应与丝杆螺母和另一个摆臂铰接，底座与摆臂铰接，滚轮、限位板固定于滚轮座上，滚轮座固定于丝杆螺母上无相对运动，扭簧套于丝杆螺母上，扭簧的一端限定于滚轮座上，另一端限定于摆臂组上，限位轴与摆臂转动连接，并穿过限位板。关门后，限制丝杆螺母位置而不直接限制丝杆，这样的终端锁闭方式可减少振动冲击对丝杆的影响，提高安全可靠性；利用塞拉门塞出塞入的运动特性，在限位板上设定相关的约束轨迹，通过这样的运动偏移和轨迹约束，限制丝杆螺母在丝杆轴向来回移动时的绕轴旋转，取消终端锁闭一般所必设的通长锁闭导向轨。
