When the wing is in the unfolding state, the working motor 633 drives the driving wheel 61 and the driving wheel 621 to synchronously and equidirectionally rotate through the driving rack 632, so that the unfolding positioning pin 3 enters the first unfolding positioning hole 211 of the connecting block 21 to fix the unfolding state of the wing, and in the process, due to the turning effect of the driven wheel 622 between the driving wheel 621 and the second sliding member 521, the second sliding member 521 gradually separates from the first folding positioning hole 212 in the process that the unfolding positioning pin 3 enters the first unfolding positioning hole 211; similarly, when the wing is in a folded state, the working motor 633 drives the driving wheel 61 and the driving wheel 621 to synchronously rotate in the same direction through the driving rack 632, so that the folding positioning pin 4 enters the first folding positioning hole 212, and the unfolding positioning pin 3 is separated from the first unfolding positioning hole 211; the working motor 633 can also drive the rack 632 to make the unfolding positioning pin 3 separate from the unfolding positioning hole one 211, and the folding positioning pin 4 separate from the folding positioning hole one 212, so as to ensure that the outer wing 2 can be smoothly folded or unfolded.

Referring to fig. 6, in order to ensure that the outer wing 2 is more stable after being unfolded and fixed, an auxiliary positioning assembly 7 for assisting the unfolding positioning pin 3 to fix the outer wing 2 in the unfolded state of the outer wing 2 is further provided in the component cavity 11.

The auxiliary positioning assembly 7 includes an auxiliary positioning pin 71, a track four 72 and a transmission gear set 73, the track four 72 and the track one 51 are respectively located at two sides of the connection port 12, the track four 72 is arranged along the length direction of the track one 51, a third sliding member 721 is connected in the track four 72 in a sliding manner, the third sliding member 721 is a rack, and the auxiliary positioning pin 71 is fixedly connected to one end of the third sliding member 721 facing the connection port 12. The transmission gear set 73 includes a transmission gear 731 and a transmission gear 732, both the transmission gear 731 and the transmission gear 732 are rotatably connected to the inner wing 1, the transmission gear 731 is engaged with the driving rack 632, and both sides of the transmission gear 732 are respectively engaged with the transmission gear 731 and the third sliding member 721.

Referring to fig. 9, the side wall of the connecting block 21 is provided with a first auxiliary positioning hole 213.

Referring to fig. 2, the inner wall of the component cavity 11 is formed with a second auxiliary positioning hole 113, and when the outer wing 2 is in the unfolded state, the first auxiliary positioning hole 213, the second auxiliary positioning hole 113 and the auxiliary positioning pin 71 are aligned.

After the outer wing 2 is in the unfolding state, the working motor 633 drives the driving wheel 61 and the transmission gear 731 to rotate in opposite directions through the driving rack 632, in the process, the unfolding positioning pin 3 enters the first unfolding positioning hole 211, and the auxiliary positioning pin 71 enters the second auxiliary positioning hole 113, so that a more stable fixing effect for the outer wing 2 is achieved.

The implementation principle of the thin folding wing and the locking mechanism thereof in the embodiment 1 is as follows: when the outer wing 2 of the wing is in the unfolded state, the working motor 633 drives the unfolding positioning pin 3 to pass through the unfolding positioning hole II 111 and enter the unfolding positioning hole I211 through the driving rack 632, and simultaneously, the auxiliary positioning pin 71 passes through the auxiliary positioning hole II 113 and enters the auxiliary positioning hole I213, so that the outer wing 2 is fixed in the unfolded state of the outer wing 2; when the outer wing 2 of the wing is in the folded state, the working motor 633 drives the folding positioning pin 4 to pass through the second folding positioning hole 112 and enter the first folding positioning hole 212 through the matching of the driving rack 632 and the main gear set 62, so as to fix the outer wing 2 in the folded state of the outer wing 2; in the process that the outer wing 2 needs to rotate freely, the working motor 633 can drive the unfolding positioning pin 3, the folding positioning pin 4 and the auxiliary positioning pin 71 to separate from the limit of the connecting block 21 through the driving rack 632, so as to achieve the purpose of free rotation of the outer wing 2.

On some wings of hypersonic aircrafts with thinner requirements on the thickness of the wings and stricter requirements on the size of structures and equipment in the thickness direction of the wings, the locking mechanism in the embodiment realizes the advantages of locking and unlocking of the wings in the folding and unfolding states by fewer structures and simpler modes, and can better meet the requirements of the hypersonic aircrafts.

In embodiment 2, the implementation principle of a thin folding wing and a locking mechanism thereof is as follows: after the outer wing 2 of the wing is in the unfolding state, the first adjusting motor 64 drives the unfolding positioning pin 3 to penetrate through the unfolding positioning hole II 111 and enter the unfolding positioning hole I211 through the first sliding piece 511, so that the outer wing 2 is fixed in the unfolding state of the outer wing 2; when the outer wing 2 of the wing is in the folded state, the second adjusting motor 65 drives the folding positioning pin 4 to penetrate through the second folding positioning hole 112 and enter the first folding positioning hole 212 through the second sliding member 521, so as to fix the outer wing 2 in the folded state of the outer wing 2; in the process that the outer wing 2 needs to rotate freely, the first adjusting motor 64 drives the unfolding positioning pin 3 to be separated from the unfolding positioning hole I211, and the second adjusting motor 65 drives the folding positioning pin 4 to be separated from the folding positioning hole I212, so that the purpose of free rotation of the outer wing 2 is achieved.

On some wings of hypersonic aircrafts with thinner requirements on the thickness of the wings and stricter requirements on the size of structures and equipment in the thickness direction of the wings, the locking mechanism in the embodiment realizes the advantages of locking and unlocking of the wings in the folding and unfolding states by fewer structures and simpler modes, and can better meet the requirements of the hypersonic aircrafts.
