Problems solved by technology

[0002] The wings of the existing flying passenger planes are relatively long, so when the flying passenger plane slows down and taxis on the runway, the wing points need to be folded upwards. A hinge folding mechanism is adopted, and the movable wing points and the contact side of the wing are provided with slopes, but there is a gap between the two. There are still small gaps; the wing of the flying car has two folds on one side of the wing, one is folded up and the other is folded down. The gap that appears when the fold is unfolded is filled with a sealed structure, but This increases the weight when flying again; the wings of combat aircraft also have the problem of large gaps when they are folded and unfolded, and these gaps will increase the technical problems of flight resistance when the aircraft or flying cars fly in the air

Embodiment Construction

[0029] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments, but the embodiments of the present invention are not limited thereto.

[0030] Such as Figure 1-Figure 2 As shown, the telescopic folding wing of the present invention includes a fixed wing 1 and a movable wing 2, wherein the fixed wing 1 and the movable wing 2 are connected by a telescopic folding device, and the movable wing 2 passes through the relative fixed wing 1. The telescopic folding device is unfolded or folded.

[0031] Such as Figure 3-Figure 4 As shown, the fixed wing of the present invention includes a lower wall plate 101, an upper wall plate 105, a rear beam 102, and a front beam 103, and the lower wall plate 101, the upper wall plate 105, the rear beam 102 and the front beam 103 are connected by fasteners.

Abstract

The invention relates to a telescopic folding device and a wing, the device comprises a telescopic mechanism and a folding mechanism, the telescopic mechanism comprises a movable end rib, at least four guide rail assemblies, at least two first drivers and at least two second drivers, the first guide rail assembly and the second guide rail assembly are arranged at one end of the movable end rib, the third and fourth guide rail assemblies are arranged at the other end of the movable end rib; the first drivers are connected with the first and second guide rail assemblies; the second drivers are connected with the third and fourth guide rail assemblies, and the movable end rib is driven by the at least two first drivers and the second drivers to do reciprocating motion; and the folding mechanism is connected with a movable end rib of the telescopic mechanism. The folding wing structure is designed, the wing tip structure folding function is achieved, meanwhile, it is guaranteed that gaps do not appear on the upper face and the lower face of the wing before folding, it is avoided that a complex sealing structure is designed due to large gaps, the completeness of the upper wing face and the lower wing face is guaranteed, and the aerodynamic performance of an aircraft is guaranteed.

Description

technical field [0001] The invention belongs to the related technical field of aviation structures and mechanisms, and in particular relates to a retractable folding device and wings. Background technique [0002] The wings of the existing flying passenger planes are relatively long, so when the flying passenger plane slows down and taxis on the runway, the wing points need to be folded upwards. A hinge folding mechanism is adopted, and the movable wing points and the contact side of the wing are provided with slopes, but there is a gap between the two. There are still small gaps; the wing of the flying car has two folds on one side of the wing, one is folded up and the other is folded down. The gap that appears when the fold is unfolded is filled with a sealed structure, but This increases the weight of the flight again; the wings of the combat aircraft also have the problem of large gaps when they are folded and unfolded, and these gaps all have the technical problem of in...
