Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0037] Such as figure 1 As shown, the integrated wing includes the wing main body 1 and the wing root joint 2. The circular part of the joint plate is the bearing 3. At the same time, there are two holes on the root plate, which are respectively the spring fixing hole 4 and the spring pin locking hole 5. . The two wings are installed on the same shaft, and are deployed by torsion springs, and locked in place by spring pins.

[0038] Such as figure 2 As shown, the rotating shaft includes a central shaft 6 for connecting and fixing with the fuselage, and an outer circular surface 7 for maintaining the stable contraction of the torsion spring, and a mounting hole 8 for a spring pin is arranged between the outer circular surface and the central shaft; The bearings of the two wing root joints are respectively fixedly connected with the central shaft on th...

Abstract

A coaxial wing folding mechanism includes two wings mounted on the same rotating shaft, deployed by torsion spring and locked in place by spring pin. The invention uses a torsion spring as a driving force and a spring pin as a locking mechanism. When the wing is folded, the launcher wall is used to restrain the wing. When the wing is deployed, the fuselage is ejected from the launcher, and the wing is deployed under the drive of torsion spring. Spring pins pop out when deployed, locking and securing the wing.

Description

technical field [0001] The invention relates to a small coaxial wing folding mechanism, which belongs to the field of aviation drones. Background technique [0002] At present, small UAVs are developing rapidly, and their application fields have been extended to military, scientific research, civilian and other fields. Traditional drones cannot be folded, and are bulky and difficult to carry. If it is designed as a detachable structure, it will bring cumbersome disassembly and assembly work during use, which is time-consuming and labor-intensive. Therefore, the folding of the wings can reduce the volume of the drone, which is convenient for transportation, portability and use. [0003] For small folding wing UAVs, the folding wing technology under the existing technical conditions has problems such as incomplete folding, slow unfolding speed, inaccurate unfolding angle, and unreliable fixing mechanism. [0004] For example, patent CN203681865U, the application date is Jan...
