Description

Technical Field

[0001] This invention relates to the field of unmanned aerial vehicle (UAV) landing gear technology, and more specifically, to a novel integrated landing gear structure for UAVs. Background Technology

[0002] Helicopters possess vertical takeoff and landing capabilities and excellent low-speed performance, making them suitable for a wide range of applications. They play an irreplaceable role not only in military operations, rescue, and transportation but also in civilian sectors. However, helicopters have high requirements for the flatness of takeoff and landing sites. Landing in rugged terrain and on ships in adverse sea conditions significantly increases the difficulty and danger, which to some extent limits the practical application scenarios of helicopters.

[0003] The landing gear, as a crucial load-bearing component of the drone's fuselage, primarily bears the loads generated during takeoff, landing, taxiing, and parking. In practice, the landing gear withstands significant loads. It must not only bear the static and dynamic loads generated when the drone contacts the ground, but also absorb and dissipate the energy generated by the relative motion between the drone and the ground. Especially during landing, the drone experiences varying degrees of impact with the ground, and the landing gear absorbs and bears the energy of these impacts. Its performance directly affects the drone's lifespan.

[0004] Currently, helicopter landing gear includes skid-type, wheeled, and crushable energy-absorbing types, all of which enable passive landing. However, existing landing gear technologies primarily focus on manufacturing materials and are designed for small, multi-rotor unmanned aerial vehicles (UAVs). Landing gear designs for lightweight unmanned helicopters (takeoff weight 450kg) are often complex and lack adaptability. Therefore, it is necessary to propose a novel integrated landing gear structure for UAVs to at least partially address the problems existing in current technologies. Summary of the Invention

[0078] The first bolt 21 has a movable rod 22 at its bottom end;

[0079] A magnetic suction plate 50 is provided with a nut 49. The nut 49 has a threaded hole. A threaded rod 43 is threadedly connected to the threaded hole.

The bottom end of the first rectangular block 46 is connected to a first rotating rod 47. The other end of the first rotating rod 47 passes through the threaded rod 43 and is connected to a second bolt 48.

[0080] A buffer block 32 is located above the nut 49. The buffer block 32 has a meshing cavity 33 inside, and a fixing block 38 is provided inside the meshing cavity 33. A first bevel gear 34 is rotatably provided at the bottom end of the inner wall of the meshing cavity 33.

[0081] The second rotating rod 42 has one end connected to the top end of the threaded rod 43 and the other end connected to the first bevel gear 34.

[0082] The fourth rotating rod 37 has one end connected to the second bevel gear 35, which meshes with the first bevel gear 34, and the other end passes through the fixed block 38 and the rotating block 36.

[0083] A fixed rod 51 is located at the top of the first bevel gear 34. A square cavity 40 is provided inside the fixed rod 51. A sliding block 39 is slidably connected inside the square cavity 40. A second spring 41 is provided between the sliding block 39 and the square cavity 40. The top of the sliding block 39 is connected to one end of a third rotating rod 31. The other end of the third rotating rod 31 passes through the fixed rod 51 and is connected to the bottom end of a circular block 23. A buffer is provided on the circular block 23. The buffer is connected to a first bolt 21.

[0084] The buffer includes:

[0085] A circular groove 24 is provided at the top of the circular block 23, and the moving rod 22 extends into the circular groove 24. Several elastic elements are evenly provided between the moving rod 22 and the circular groove 24.

[0086] Elastic cloth 25, which is sleeved on the movable rod 22, and the outer side of the elastic cloth 25 is connected to the inner wall of the circular groove 24;

[0087] The elastic element includes:

[0088] A buffer seat 26 is provided on the inner wall of a circular groove 24. A buffer groove 27 is provided in the buffer seat 26. A buffer rod 29 is slidably connected in the buffer groove 27. A third spring 28 is provided between the buffer rod 29 and the buffer groove 27. A fan-shaped plate 30 is provided at the other end of the buffer rod 29.

[0089] A sector-shaped groove 52 is provided on the movable rod 22, and the sector-shaped block 30 is inserted into the sector-shaped groove 52.

[0090] The working principle and beneficial effects of the above technical solution are as follows: In actual use, when the landing gear is installed on the UAV, the magnetic plate 50 is attracted to the bent tube. Then, the rotating block 36 with the screw hole is rotated by a screwdriver. The rotating block 36 drives the second bevel gear 35 to rotate through the fourth rotating rod 37. The second bevel gear 35 drives the second rotating rod 42 and the fixed rod 51 to rotate through the first bevel gear 34. The second rotating rod 42 drives the threaded rod 43 to rotate. When the threaded rod 43 rotates, it moves downward in the nut 49. At the same time, the threaded rod 43 drives the first rotating rod 47 to rotate through the rectangular block 46. The first rotating rod 47 drives the second bolt 48 to be screwed into the bent tube, completing the fixing of the bent tube of the connecting device; the fixed rod 51 drives the square block to rotate through the rectangular block 46. 39 drives the third rotating rod 31 to rotate, and the third rotating rod 31 drives the moving rod 22 to rotate through the round block 23 and the sector block 30. The moving rod 22 drives the first bolt 21 to rotate, so that the first bolt 21 is screwed into the landing gear mounting hole of the UAV, so that the connecting device is fixed to the UAV, thereby completing the rapid installation of the landing gear and saving time in the UAV production process; at the same time, during installation, workers only need to be in the vertical direction to complete the installation of the landing gear, avoiding the need for workers to install it under the UAV, reducing the labor intensity of the workers; and the landing gear installed by the UAV through the connecting device, through the friction between the square block 39 and the square cavity 40 and the action of the second spring 41, can play a buffering and shock absorption role when the UAV lands.

[0091] When the drone lands and the landing gear touches the ground, when the landing gear is subjected to a horizontal force, the circular block 23 will move relative to the moving rod 22, thereby causing the third spring 28 to deform, which plays a buffering role and prevents the drone from being subjected to excessive impact force, which could cause the landing gear and the drone to loosen.

[0092] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0093] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.
