The invention belongs to the field of civil aircraft cabin door mechanism design, and relates to an aircraft cabin door bidirectional locking mechanism. The upper driving shaft and the lower follow-up shaft are hinged to a cabin door structure, linkage is achieved between the upper driving shaft and the lower follow-up shaft through an upper rocker arm, a connecting rod and a lower rocker arm, an arc track is arranged on the lower rocker arm, a roller rocker arm is fixedly connected to the control shaft, a roller is hinged to the end of the roller rocker arm, and the roller is matched with the inner wall or the outer wall of the far end of the arc track. And locking in an opening state and a closing state is realized respectively. According to the invention, the arc surface is matched with the roller, so that the reverse driving torque of the contact position is eliminated, and the locking capability of the mechanism is obviously improved; locking of a closed state and an open state is achieved through the arc double-side characteristics of one mechanism, the mechanism form is simplified, the number of the mechanisms is reduced, and the product weight is reduced; the two-way locking device can meet the adjustment and optimization of various spaces, and can be popularized and applied to various cabin door mechanisms with two-way locking requirements.

    本发明属于民用飞机舱门机构设计领域,涉及一种飞机舱门双向锁定机构。具有与舱门结构铰接的上部驱动轴、下部随动轴和控制轴,上部驱动轴与下部随动轴通过上摇臂、连杆和下摇臂实现联动,下摇臂上设有圆弧轨道,控制轴上固接滚轮摇臂,滚轮摇臂端部铰接滚轮,滚轮与圆弧轨道远端的内壁或外壁配合,分别实现打开状态和关闭状态下的锁定。本发明采用圆弧表面与滚轮配合,消除了接触位置的反向驱动力矩,显著提升了机构的锁定能力;本发明一套机构的圆弧双侧特征实现了关闭状态和打开状态的锁定,简化机构形式,减少了机构数量,降低了产品重量;本发明能够满足多种空间的调整、优化,可推广应用到各种具有双向锁定需求的舱门机构上。
