Abstract

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.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to a folding device, a propeller, a rotor module and flight equipment. Background technique [0002] When the rotor of the rotorcraft is unfolded, the size is too large, which takes up a lot of space during sea and land transportation, and the risk of the blades being impacted by the outside is relatively high, so the blades need to be folded and stored. However, under normal circumstances, it is difficult and risky to manually store the blades, and automatic folding and storage of the blades is required. [0003] In related technologies, folding hinges or hydraulic cylinders are usually used to automatically store the blades, which has a complex structure and causes the aircraft to be too heavy. Contents of the invention [0004] Embodiments of the present application provide a folding device, a propeller, a rotor module, and flight equipment. [0005] According to t...
