The invention relates to a folding device, a propeller, a rotor wing module and flight equipment. The folding device comprises a fixed seat, a movable seat, a locking mechanism and a driving mechanism. The fixed seat is used for being connected with a propeller hub of a propeller, the movable seat is rotatably connected to the fixed seat and used for being connected with blades of the propeller, the movable seat is provided with a matching part, the locking mechanism is arranged on the fixed seat and comprises a lock pin capable of moving relative to the fixed seat, and when the folding device is in an unfolded state, the lock pin is limited to the matching part. And the movable seat is fixed relative to the fixed seat. The driving mechanism comprises a driving assembly connected to the fixed seat, a first transmission assembly connected to the driving assembly, a second transmission assembly connected between the first transmission assembly and the lock pin, and a third transmission assembly connected between the first transmission assembly and the movable seat. Therefore, power switching of the second transmission assembly or the third transmission assembly is achieved through the single-input and double-output principle of the first transmission assembly, and the structure of the folding device is simplified.
本申请涉及一种折叠装置、螺旋桨、旋翼模组及飞行设备。折叠装置包括固定座、活动座、锁定机构及驱动机构。固定座用于连接螺旋桨的桨毂,活动座可转动地连接于固定座,并用于连接螺旋桨的桨叶,活动座设有配合部,锁定机构设置于固定座,锁定机构包括可相对固定座活动的锁销,折叠装置处于展开状态时,锁销限位于配合部,使活动座相对于固定座固定。驱动机构包括连接于固定座的驱动组件、连接于驱动组件的第一传动组件、连接于第一传动组件与锁销之间的第二传动组件、及连接于第一传动组件与活动座之间的第三传动组件。因此,通过第一传动组件的单输入、双输出的原理实现第二传动组件或第三传动组件的动力切换,简化了折叠装置的结构。
