Embodiment

[0024] Such as figure 1 with figure 2 As shown, the present invention provides an outer wing folding mechanism of an aircraft, including a fixed wing 1, one side of the fixed wing 1 is connected with a folding wing 3 through a hinge support mechanism 2, and the hinge support mechanism 2 makes the fixed wing 1 It is an integral structure with the folding wing 3, and also supports and fixes the folding wing 3; the hinge support mechanism 2 includes a base 4 and an ear piece 5, and the ear piece 5 is fixed on the base through a pin shaft connection. On the seat 4, the folding wing 3 can rotate relative to the fixed wing 1 along the hinge support mechanism 2 to complete the folding and unfolding process of the wing; the base 4 and the spar of the fixed wing 1 are fixed by bolts, and the ear The sheet 5 and the spar of the folding wing 3 are fixed by bolt connection.

[0025] Such as image 3 As shown, a folding power mechanism 6 is arranged between the fixed wing 1 and the fol...

Abstract

The invention discloses an outer wing folding mechanism of an aircraft, which comprises a fixed wing, one side of the fixed wing is connected with a folding wing through a hinge support mechanism, and a folding power mechanism is arranged between the fixed wing and the folding wing , the folding power mechanism includes a servo motor, a screw rod, a folding shaft and a sleeve, the servo motor is fixedly installed on the spar of the fixed wing through a motor base, and the output shaft of the servo motor is connected to the screw rod through a joint The screw nut adapter is sleeved on the screw rod, the screw nut adapter is fixedly connected with a folding shaft, the inner wall of the sleeve is provided with a spiral groove, and the folding shaft The shaft is arranged in the sleeve, and the expansion shaft is engaged with the spiral groove. The sleeve is fixedly connected to the spar of the folding wing, and has a relatively large transmission ratio, which increases during the wing folding process. The output torque is increased, the wings can be easily unfolded, and it has the ability of one-way self-locking.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an outer wing folding mechanism of an aircraft. Background technique [0002] The foldable 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 experimental stage, it has not...
