Embodiment 1

[0036] In the prior art, in order to ensure the stable flight of the aircraft in the air, wings are generally symmetrically arranged on both sides of the aircraft, and its purpose is mainly to provide buoyancy for the aircraft to ensure the stable flight of the aircraft. The design is fixed, that is, the wings are fixed on the body of the aircraft. When the aircraft flies with obstacles or in a narrow range, because the wings are of a fixed structure, it is easy to collide with surrounding obstacles and damage the aircraft. In addition, this aircraft cannot change the shape of its wings, which makes it not flexible enough to fly. There is room for further improvement.

[0037] combine figure 1 and Figure 4 , a collapsible folding wing of this embodiment, comprising a first bracket 311 and a second bracket 321 hingedly installed on one side of the body 100, such as figure 1As shown, the body 100 is provided with an upper fixed block 310 and a lower fixed block 320 along its...

Embodiment 2

[0048] A kind of collapsible folding wing of this embodiment is basically the same as embodiment 1, further: combine figure 1 , in this embodiment, the third bracket 330 and the fourth bracket 340 are designed to be parallel to each other, and the second bracket 321 drives the fourth bracket 340 to move during the stretching process. Both ends of the third bracket 330 are connected, therefore, the third bracket 330 also moves together with the fourth bracket 340, and also drives the fifth bracket 350 and the sixth bracket 360 to move together to realize the expansion or contraction of the wings.

[0049] In this embodiment, the end of the fourth bracket 340 close to the body 100 is curved, and the curved end surface includes a first end surface 3401 and a second end surface 3402, combined with figure 1 and image 3 , the first end surface 3401 and the second end surface 3402 are arc-shaped, and the concavity direction of the arc is toward the middle of the curved shape, the t...

Embodiment 3

[0053] A retractable foldable wing of this embodiment is basically the same as that of Embodiment 2, and further: in this embodiment, on the contacting surface between the second bracket 321 and the fourth bracket 340, mutually engaging wheels are correspondingly provided. teeth, when the second bracket 321 moves, the fourth bracket 340 rotates, and under the effect of gear teeth meshing, both the second bracket 321 and the fourth bracket 340 rotate synchronously, that is, the two rotate relatively. On the one hand, this structure can Improve the efficiency of wing expansion or contraction. On the other hand, when the gear teeth mesh and rotate, the second bracket 321 will receive the force transmitted by the fourth bracket 340 through the gear teeth, so that the second bracket 321 will rotate, especially when the wings are unfolded, further avoiding The occurrence of the fact that the second bracket 321 is attached to the body 100 .

[0054] In this embodiment, the gear teeth...

Abstract

The invention discloses a retractable folding wing and belongs to the technical field of wing design. The retractable folding wing comprises a first support and a second support which are hinged on one side of a machine body. The end, away from the machine body, of the first support is hinged to the ends, close to the machine body, of a third support and a fourth support, the end, away from the machine body, of the second support is hinged to the end, close to the machine body, of the fourth support, the end, away from the machine body, of the third support is hinged to the end, close to the machine body, of a fifth support, the end, away from the machine body, of the fourth support is hinged to the ends, close to the machine body, of the fifth support and a sixth support, the end, away from the machine body, of the sixth support is connected with the fifth support, the second support is of a retractable structure, the side wall of the second support is hinged to a driving element, andthe driving element is arranged on the machine body. The supports are connected in a hinged mode, one support is controlled to stretch and retract so as to drive other supports to move, and the wingis flexibly stretches and retracted.

Description

technical field [0001] The invention relates to the technical field of wing design, in particular to a retractable folding wing. Background technique [0002] In nature, birds have undergone long-term evolution, and their forelimbs have evolved into wings, through which they can fly or glide, making them the overlords of the sky. With the rapid development of science and technology, human beings imitate the flying mode of bird wings and gradually march into the sky. Therefore, airplanes, aircrafts, drones, etc. have emerged as the times require. [0003] In order to ensure the normal flight of the flight equipment, the structural design of its wings is particularly important. With the continuous advancement of research technology, the wings of the aircraft in the prior art provide buoyancy for the aircraft body through the wings in order to achieve flight, but the wings are fixed. The main body of the aircraft is always in a fixed and unfolded state. In addition, some aircr...
