Abstract

The invention discloses an outer wing folding mechanism of a variant aircraft. The transmission ratio of the existing planetary wheel-type outer wing folding mechanism is relatively small, and it does not have one-way self-locking ability, so it has high requirements for the selection of servo motors. The invention includes a hinge support mechanism, a power transmission mechanism of a folding mechanism and a coaxial folding joint hinge mechanism of an outer wing; the hinge support mechanism includes a base and a first ear piece; the power transmission mechanism of a folding mechanism includes a servo motor, Lead screw, lead screw nut, first gear, second gear, third gear, fourth gear, fifth gear and sliding rod; outer wing coaxial folding joint hinge mechanism includes active bevel gear, first driven A bevel gear, a driving external co-rotating gear, a driven external co-driving gear, a driving gear, a driven gear, a second lug, a second driven bevel gear, and a third lug. The invention has a large reduction ratio, can fold and expand a large outer wing, and has one-way self-locking ability.

Description

technical field [0001] The invention belongs to the technical field of morphing aircraft, and in particular relates to an outer wing folding mechanism of a morphing aircraft. Background technique [0002] The morphing aircraft is proposed from the perspective of bionics, which can continuously and adaptively adjust the wing shape according to the flight mission and the external environment to maintain the optimal wing load. The existing planetary wheel-type outer wing folding mechanism can realize the outer wing folding movement through its relatively compact and simple mechanism, but because its transmission ratio is not large and it does not have one-way self-locking ability, this Higher requirements are put forward for the selection of the servo motor; and the servo motor needs to be powered for a long time during the flight to maintain its flight attitude. Since the wing folding mechanism using thermopolymerization actuators and piezoelectric actuators is still in the e...
