Embodiment Construction

[0025] The specific implementation manner of the present invention will be described in detail in conjunction with the summary of the invention and the accompanying drawings.

[0026] Referring to the accompanying drawings, the adaptive landing device is installed under the rotor steering gear cover 3 of the multi-rotor UAV, and installed through a special installation frame 4 . Each leg includes a mechanical link 5 , a joint driving device 6 and a buffer foot 7 , and its control system 8 is integrated and installed on the fuselage 1 .

[0027] The mechanical connecting rod 5 is made of high-strength aluminum alloy, and is divided into a femoral joint 9 and a tibial joint 10 , both of which are hollow cylindrical structures, so as to facilitate the wiring of the force sensor 12 . A joint driving device 6 is connected between the femoral joint 9 and the installation frame 4, between the femoral joint 9 and the tibial joint 10, and the joint driving device 6 is fixed on the mech...

Abstract

The invention discloses a self-adaptive landing gear for a multi-rotor unmanned aerial vehicle. The self-adaptive landing gear comprises multiple legs; each leg comprises a joint driving device, a mechanical connecting rod and a buffering foot which are connected sequentially as well as a control system mounted on a vehicle body; each mechanical connecting rod comprises a thigh and a tibia; each joint driving device is connected between the corresponding thigh and the corresponding tibia; and each buffering foot comprises a micro force sensor and a spherical hinge which are connected sequentially. The self-adaptive landing gear for the multi-rotor unmanned aerial vehicle is based on the bionic concept and refers to the manners that flying insects stay in positions such as the ground, treesand the like, so that the landing gear has the higher flexibility and the higher intelligent level, and the defect that traditional multi-rotor aircrafts have relatively high requirements for landingenvironments is overcome.

Description

technical field [0001] The invention belongs to the field of multi-rotor UAVs, and more particularly relates to the design of a multi-rotor UAV landing device with adaptive terrain capability. Background technique [0002] Drone technology has advanced by leaps and bounds in recent years. Due to its small size, low cost, good maneuverability, strong survivability, and no risk of casualties, it not only occupies an extremely important position in modern military warfare, but also has a very broad prospect in the civilian field. From a technical point of view, the current UAVs mainly include unmanned fixed-wing UAVs, unmanned vertical take-off and landing aircraft, unmanned helicopters and multi-rotor UAVs. In contrast, multi-rotor drones have many advantages such as simple structure, flexible control, vertical take-off and landing, hovering or inverted flight, etc., and can be controlled by wireless remote control to complete tasks such as tracking and shooting. [0003] At...
