Emergency unlocking device for locking mechanism of sliding plug door of urban rail vehicle
The invention relates to an emergency unlocking device for a locking mechanism of a sliding plug door of an urban rail vehicle. The emergency unlocking device for the locking mechanism of the slidingplug door of the urban rail vehicle is characterized in that the unlocking device is located at the end part of a screw rod and drives the screw rod through the rotation of a kinematic pair connectedwith the screw rod, so that the unlocking process of the mechanism is converted into the rotation process of the screw rod; and when the screw rod rotates by a certain angle, the mechanism is changedinto an unlocking state from a locking state, so that the unlocking action of the passive locking door mechanism is realized; and the kinematic pair is a sector gear and a screw rod gear, the lockingmechanism is unlocked through rotation after meshing, and therefore the unlocking purpose of the passive locking door mechanism is realized. The emergency unlocking device for the locking mechanism ofthe sliding plug door of the urban rail vehicle has the advantages of being simple in structure, small in occupied space and high in reliability and universality; and the structure can meet the dooropening requirement of emergency unlocking of an urban rail vehicle door system, and can be used for a sliding plug door driven by a motor-screw rod so as to realize unlocking operation in an emergency state to open the vehicle door.
本发明是一种用于城轨车辆塞拉门锁闭机构的紧急解锁装置，其特征是解锁装置位于丝杆的端部，该装置通过一个与丝杆相连的运动副的转动带动丝杆，从而将机构的解锁过程转化成丝杆的转动过程，当丝杆转动一定角度，机构会从锁闭状态变为解锁状态，以实现无源闭锁门机构的解锁动作；所述的运动副为扇形齿轮与丝杆齿轮，通过啮合后的转动将锁闭机构解锁，以实现无源闭锁门机构的解锁目的；本发明的优点：结构简单，占用空间较小，同时具有很高的可靠性和通用性，该结构能够满足城轨车辆门系统紧急解锁的开门要求，可用于用电机‑丝杆带动的塞拉门上，以实现紧急状态下解锁操作来打开车门。
