At the same time, it absorbs impact energy during takeoff and landing, protects the fuselage and internal equipment, and improves flight safety and reliability. Existing drones are fixed in structure and often show insufficient adaptability when facing complex and changeable outdoor environments. Especially on uneven ground conditions, drones are prone to tipping over due to unstable landing gear support, causing damage to external components such as blades and cameras, which not only affects the smooth progress of the mission but may also cause unnecessary economic losses.
[0003] Therefore, an environmentally adaptable UAV landing gear has been developed that can adjust the height and angle of the soft cushion to adapt to smooth landing in different terrain environments and avoid damage to the UAV. Utility Model Content

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0017] An environmentally adaptable UAV landing gear, such as Figure 1 and Figure 2As shown, it includes a mounting frame 1, a fixed block 2, a motor 3, a rotating shaft 4, a bevel gear set 5, an adjustment component, a buffer component and a rotating component. The front and rear sides of the mounting frame 1 are connected to the fixed block 2. The mounting frame 1 has six mounting holes for easy installation on the drone. The left and right sides of the fixed block 2 are connected to the motor 3. The left and right sides of the lower part of the mounting frame 1 are rotatably connected to the rotating shaft 4. The motor 3 is connected to the adjacent rotating shaft 4 with a bevel gear set 5. The rotating shaft 4 is provided with an adjustment component, the adjusting component is provided with a buffer component, and the buffer component is provided with a rotating component.
[0018] like Figure 2 and Figure 3 As shown, the adjustment assembly includes a mounting block 6, an electric push rod 7 and a connecting block 8. The front and rear sides of the rotating shaft 4 are connected to the mounting blocks 6. The mounting blocks 6 are each equipped with an electric push rod 7. The telescopic ends of the electric push rod 7 are each connected to a connecting block 8.
[0019] like Figure 1 and Figure 3 As shown, the buffer assembly includes a sleeve 9, a sliding frame 10 and a telescopic spring 11. The sleeve 9 is connected to the lower side of the connecting block 8, the sliding frame 10 is slidably connected inside the sleeve 9, and the telescopic spring 11 is connected between the sliding frame 10 and the adjacent sleeve 9.
[0020] like Figure 1 and Figure 3 As shown, the rotating assembly includes a universal shaft 12 and a soft pad 13. The lower side of the sliding frame 10 is rotatably connected to the universal shaft 12, and the lower side of the universal shaft 12 is connected to the soft pad 13. The soft pad 13 is made of rubber material to facilitate impact buffering.
[0021] When using the present invention, first install the device on the drone through the mounting frame 1. When the drone takes off and lands, the soft pad 13 contacts the landing ground, squeezing the soft pad 13 upward, causing the sliding frame 10 to slide upward on the sleeve 9. Under the action of the telescopic spring 11, the impact force of the drone landing is buffered. The electric push rod 7 on the mounting block 6 is started, so that the telescopic end of the electric push rod 7 is pushed out, and the height of the soft pad 13 can be adjusted. At the same time, when the soft pad 13 contacts the ground, the soft pad 13 can be rotated on the universal shaft 12, so that the soft pad 1 3 maintains parallel contact with the landing ground, thereby achieving the effect of being able to adjust the height and angle of the soft cushion 13 to adapt to a smooth landing in different terrain environments and avoid damage to the drone. After the drone is used, the motor 3 on the starting fixing block 2 can be controlled to rotate the rotating shaft 4, and the meshing movement of the bevel gear set 5 can rotate the rotating shaft 4, driving the mounting block 6 to rotate, so that the electric push rod 7 can be rotated and retracted, reducing the space occupied by the device, thereby facilitating the storage of the drone.
