Description

Technical Field

[0002] With the strong promotion of the low-altitude economy, drones are being used in an increasingly wide range of industries. This has led to a magnification of the shortcomings of drones in terms of adaptability to application environments, transportation, storage, and maintenance. The drone industry is also racing to optimize the inherent characteristics and weaknesses of drones.

[0003] The wings of drones occupy a significant area during parking and transportation. Folding the wings can reduce the space required for parking and storage, especially in space-constrained locations such as aviation clubs, small airports, and shipboard facilities. Folding the drone wings allows for the storage of more drones, improving space utilization. With the continuous development of various aviation technologies, the technical requirements for folding wings are also increasing, such as requiring simpler and more reliable folding mechanisms, and faster and more stable folding processes.

Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] Combination Figure 1 and Figure 2 As shown, this utility model discloses a folding wing, including a fixed wing section 8 and a folding wing section 9, and also includes a connecting mechanism for connecting the fixed wing section 8 and the folding wing section 9 to realize wing folding, and a drive mechanism for providing power to the connecting mechanism. The connecting mechanism includes a fixed wing connector 4 installed on the fixed wing section 8, a folding wing connector 5 installed on the folding wing section 9, and a linkage mechanism connecting the fixed wing connector 4 and the folding wing connector 5. The linkage mechanism is drivenly connected to the drive mechanism.

[0026] This invention involves splitting the wing of a drone into a fixed wing segment and a folding wing segment, and connecting the fixed wing segment and the folding wing segment through a connecting mechanism that enables folding. The connecting mechanism is driven by a drive mechanism, so that the fixed wing segment remains stationary while the folding wing segment drives the connecting mechanism through the drive mechanism, thereby causing it to flip upward and achieve a 180° folding of the wing.

[0027] like Figures 1 to 5As shown, in one embodiment, the fixed wing connector 4 includes a first mounting base 41 and a first fixed end 42 and a second fixed end 43 located on the first mounting base. The folding wing connector 5 includes a second mounting base 51 and a third fixed end 52 and a fourth fixed end 53 located on the second mounting base. The first mounting base 41 of the fixed wing connector 4 is fixedly installed inside the fixed wing segment 8, and the second mounting base 51 of the folding wing connector 5 is fixedly installed inside the folding wing segment 9. Specifically, the first mounting base 41 of the fixed wing connector 4 is fixedly installed at the top of the internal space of the fixed wing segment 8, and the second mounting base 51 of the folding wing connector 5 is fixedly installed at the top of the internal space of the folding wing segment 9. After folding 180°, the second mounting base 51 of the folding wing connector 5 is located at the bottom of the internal space of the folding wing segment 9.

[0028] In one embodiment, the linkage mechanism includes a first linkage assembly 6 and a second linkage assembly 7; one end of the first linkage assembly 6 is rotatably connected to the first fixed end 42 of the fixed wing connector 4 via a first pivot 61, and the other end is rotatably connected to the fourth fixed end 53 of the folding wing connector 4 via a second pivot 62; one end of the second linkage assembly 7 is rotatably connected to the second fixed end 43 of the fixed wing connector 4 via a third pivot 71, and the other end is rotatably connected to the third fixed end 52 of the folding wing connector 5 via a fourth pivot 72.

[0029] The first linkage assembly 6 includes two or more first long linkages 63, and the second linkage assembly 7 includes two or more second long linkages 73. The first long linkages 63 and the second long linkages 73 are connected by a fifth rotating shaft 64 and a sixth rotating shaft 74; the fifth rotating shaft 64 is drivenly connected to the drive mechanism. Preferably, there are four first long linkages 63 and two long linkages 73, and their shape is similar to a U-shape, with both ends rotatably connected to the connecting members via rotating shafts.

[0030] In one embodiment, the drive mechanism includes a cylinder mounting base 1 fixed to the bottom of the internal space of the fixed wing section 8, a cylinder 2 mounted on the cylinder mounting base 1, and a piston connecting rod 3 driven by the cylinder 2. The piston connecting rod 3 is connected to the fifth rotating shaft 64 of the linkage mechanism. The cylinder mounting base 1 provides power to the linkage mechanism. The cylinder 2 is mounted inside the wing or fuselage and contains liquid fuel. When needed, the fuel is burned to push the piston connecting rod 3. The piston connecting rod 3 transmits the kinetic energy generated by the cylinder 2 to the fifth rotating shaft 64. The fifth rotating shaft 64 drives the first connecting rod assembly 6, which is linked with the second connecting rod assembly 7, causing the folding wing section to flip upward.

[0031] In a preferred embodiment, the first fixed end 42 of the fixed wing connector 4 and the third fixed end 52 of the folding wing connector 5 include a limiting mechanism, and the first rotating shaft 61 and the fourth rotating shaft 72 are limited in movement within the limiting mechanism.

[0032] This utility model also discloses a drone including the above-mentioned folding wing. The drone employing the above-mentioned folding wing has the following advantages:

[0033] (1) The 180° folding wings can significantly reduce the overall size of the drone, making it easier to store in a limited space and adapt to the loading space requirements of different transportation vehicles, thus facilitating the transfer and deployment of the drone.

[0034] (2) When performing routine maintenance, repair and component replacement on the UAV, the 180° folding wing can provide maintenance personnel with a wider operating space, making it easier to access key areas such as the internal structure of the wing and the connection between the wing and the fuselage. This facilitates the identification and resolution of potential mechanical and electrical faults, improves maintenance efficiency, and ensures the reliability and availability of the UAV.

[0035] (3) 180° folding wings can more easily pass through narrow passages and enter cramped spaces in some special usage environments, such as when it is necessary to transport drones to temporary take-off and landing points in remote mountainous areas or narrow island airports, ensuring that drones can arrive smoothly and be put into use.

[0036] (4) After the wings are folded 180°, it is easier to carry out maintenance work such as cleaning and anti-corrosion treatment of the wing surface. It is possible to perform more detailed maintenance on each part of the wing and extend the service life of the wing and even the entire UAV.
