Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and in particular to a foldable wing. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices, or operated autonomously, either completely or intermittently, by an onboard computer. The wings of UAVs are typically made of composite materials, which provide a certain level of strength while maintaining a relatively light weight, effectively assisting in flight.

[0003] In existing technologies, drones generally use fixed wings. Fixed wings take up a lot of space during storage and transportation, making them inconvenient to store and transport. Sometimes, the wings need to be repeatedly disassembled and reassembled, making the operation process complicated. Utility Model Content

[0024] like Figures 1 to 6 As shown, this embodiment proposes a foldable wing, including a first folding wing 100; a second folding wing 200, which is hinged to the first folding wing 100 via a hinge structure 210; a positioning plate 300 disposed within the first folding wing 100; a driving member 400, with its end hinged to the positioning plate 300; a first connecting rod disposed within the first folding wing 100, with its first end 510 hinged to the first folding wing 100 and its middle section hinged to the output end of the driving member 400, the driving member 400 being used to drive the first connecting rod to rotate around its first end 510; and a second connecting rod 600, including a third end 610 and a fourth end 620, with the third end 610 hinged to the second end 520 of the first connecting rod and the fourth end 620 hinged to the second folding wing 200.

[0025] The application of the above-mentioned foldable wing has at least the following beneficial effects: the first link is driven to rotate around the first end 510 by the drive component 400, which in turn drives the second link 600 to rotate, that is, drives the second folding wing 200 to rotate and fold around the hinge structure 210. This makes full use of the internal space of the wing, simplifies the folding mechanism, makes the drone easier to store, and at the same time, the structure is simple, realizing the drone's lightweight, easy transportation and easy maintenance.

[0026] According to some embodiments of this utility model, the first connecting rod is configured as an L-shaped rod 500. The first end 510 of the L-shaped rod 500 is hinged to the first folding wing 100, the vertex of the L-shaped rod 500 is hinged to the output end of the driving member 400, and the second end 520 of the L-shaped rod 500 is hinged to the third end 610 of the second connecting rod 600. The driving member drives the vertex of the L-shaped rod 500 to move towards the second folding wing 200. Under the action of the first end 510, the vertex swings along the hinge point of the first end 510, causing the second end 520 to swing along the hinge point of the first end 510 as well. At the same time, the second connecting rod 600... The second folding wing 200 tends to move towards the second folding wing 200. Since the second folding wing 200 is connected to the first folding wing 100 through the hinge structure 210, the second link 600 pushes the second folding wing 200 to swing along the hinge position of the hinge structure 210 and fold towards the first folding wing 100, thereby completing the wing folding action. The unfolding action is the opposite. The drive member 400 drives the apex of the L-shaped rod 500 to pull back, causing the apex of the L-shaped rod 500 to swing in the opposite direction along the hinge point of the first end 510. At the same time, the above-mentioned structural actions produce corresponding reverse actions, thereby completing the wing unfolding.

[0027] In some other embodiments, the first link can also be configured as a straight rod, and the output end of the drive member 400 can be hinged to the middle section of the straight rod to achieve the same technical effect as above. Using an L-shaped rod 500 can make the force on the first link more distributed and reasonable, and the position where the first link is hinged to the drive member 400 is not easily pushed and broken or pulled apart, and the overall structure has better rigidity.

[0028] According to some embodiments of this utility model, the first connecting rod has two members. The apexes of the two L-shaped rods 500 are connected by a first stop bolt 530 and are both hinged to the rod body of the first stop bolt 530. The output end of the driving member 400 is hinged to the rod body of the first stop bolt 530 and is located between the two L-shaped rods 500. It should be noted that the stop bolt is also called a shoulder bolt, a stop bolt, a stop bolt, or a brake bolt. In addition to having a threaded rod section, it also has a smooth shaft section, which can be used for hinge connection. Moreover, its smooth shaft section can reduce the friction between the connecting structures, making the rotation smoother.

[0029] According to some embodiments of this utility model, the second ends 520 of the two L-shaped rods 500 are connected by the second bolts 630 and are both hinged to the rod body of the second bolts 630. The third end 610 of the second connecting rod 600 is hinged to the rod body of the second bolts 630 and is located between the two second ends 520. By setting the output end of the driving member 400 and the third end 610 of the second connecting rod 600 between the two L-shaped rods 500, the swing of the entire connecting rod structure is more stable and reliable.

[0030] According to some embodiments of the present invention, a first rib plate 110 is provided inside the first folding wing 100, and a first support 120 is provided on the first rib plate 110. The first end 510 of the L-shaped rod 500 is hinged to the first support 120. A second rib plate 220 is provided inside the second folding wing 200, and a second support 230 is provided on the second rib plate 220. The fourth end 620 of the second connecting rod 600 is hinged to the second support 230. Two third supports 310 are provided on the positioning plate 300. A third support 310 is hinged to each side of the end of the driving member 400.

[0031] According to some embodiments of this utility model, the driving component 400 is provided as an electric actuator or a pneumatic cylinder, or it can be provided as an oil cylinder or a hydraulic cylinder.

[0032] According to some embodiments of the present invention, the first folding wing 100 is provided with an openable cover 130, and the positioning plate 300 is located inside the cover 130. When maintenance is required, the cover 130 can be opened.

[0033] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

[0034] Although some embodiments of the present invention have been shown and described in this specification, the present invention should not be limited to the above embodiments. As long as they achieve the technical effects of the present invention by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles of this disclosure, without departing from the principles and purpose of the present invention, should be included within the scope of protection of this disclosure and should be considered to fall within the protection scope of the present invention.
