The electrically-driven active cabin door uplock. The uplock comprises an electric actuating mechanism and a four-connecting-rod mechanism, wherein the four-connecting-rod mechanism comprises a support (11), a rocker arm (12) serving as an input end, a lock hook (6) serving as an output end and a connecting rod (7) between the rocker arm (12) and the lock hook (6), and the electric actuating mechanism enables the rocker arm (12) to rotate through a lead screw connecting rod (4); and finally, the lock hook (6) is rotated through the connecting rod (7), locking or unlocking of the cabin door upper lock is achieved, and the cabin door locking device further comprises a state keeping device for keeping the unlocking or locking state after the cabin door upper lock is locked or unlocked. The electrically-driven active cabin door uplock is compact and reasonable in arrangement, and requirements for force output, installation coordination and weight are met; besides, the lock hook drives thelock ring on the cabin door to be locked in an active mode, and therefore it can be guaranteed that the cabin door can be reliably locked even under the condition that large deformation exists in thecabin door.
本发明公开一种电驱动的主动舱门上位锁,包括电作动机构和四连杆机构,所述四连杆机构包括支架(11)、作为输入端的摇臂(12)、作为输出端的锁钩(6)、以及在摇臂(12)和锁钩(6)之间的连杆(7),所述电作动机构通过丝杠连杆(4)使摇臂(12)转动,最终通过连杆(7)使锁钩(6)转动,实现舱门上位锁上锁或开锁,还包括在舱门上位锁上锁或开锁后,保持开锁或上锁状态的状态保持装置。本发明的电驱动的主动舱门上位锁布置紧凑合理,兼顾了力输出、安装协调和重量方面的要求。另外,本发明的主动舱门上位锁置以主动的方式由锁钩带动舱门上的锁环上锁,因此可以保证在舱门即使存在较大变形的情况下,舱门也能可靠上锁。
