Description

Technical Field

[0001] This utility model relates to the field of landing gear technology, and in particular to an intelligent landing gear for adaptive terrain unmanned aerial vehicles. Background Technology

[0002] A drone is a powered, unmanned, reusable aircraft that can fly autonomously and complete specific tasks through remote control or pre-programmed procedures. Drones can be classified into various types according to different standards. For example, according to the application field, they can be divided into military drones and civilian drones; according to the flight platform configuration, they can be divided into fixed-wing drones, rotary-wing drones, unmanned airships, paragliding drones, flapping-wing drones, etc.; according to the size, they can be divided into micro drones, light drones, small drones, medium drones, and large drones.

[0003] The utility model patent with publication number CN219339752U discloses a landing gear and a drone. The patent describes a system where, "when the landing gear is needed, the movable frame is controlled to rotate relative to the connecting frame to an extended state, allowing the landing gear to support the drone. A locking component is also controlled to lock the rotation of the movable frame relative to the connecting frame, ensuring the stability and reliability of the landing gear. When the landing gear is not needed, the locking component is controlled to unlock the rotation of the movable frame relative to the connecting frame, and the movable frame is controlled to rotate relative to the connecting frame to a retracted state, allowing the ends of the two movable frames furthest from the connecting frame to move closer together, reducing the space occupied by the landing gear and facilitating its storage or transport." While this solves problems such as "inconvenient storage and transport, and poor portability," when the drone lands on uneven surfaces, its landing pad, typically long and narrow, is difficult to adapt to changes in terrain, causing the drone to tilt or even tip over after landing, affecting its landing safety.
