Abstract

The invention belongs to the technical field of unmanned aerial vehicles and discloses a shock-absorption landing gear of a light rotor unmanned aerial vehicle. The shock-absorption landing gear comprises a base, threaded holes used for being connected with bolts on the unmanned aerial vehicle are formed in the top of the base, and a microcontroller, a jacketed elevator and a level sensor are further fixed in the base, wherein the level sensor is used for monitoring the levelness of the landing gear and transmitting monitored information to the microcontroller, and the microcontroller is usedfor analyzing the received information of the levelness of the landing gear and controlling a motor to work; the motor is arranged on the base and drives the jacketed elevator to work to adjust the levelness of the landing gear, and one end of the jacketed elevator is fixedly connected with a connecting piece made of an aluminum alloy material. The height of the landing gear can be automatically adjusted according to terrains, and thus the landing gear of the light rotor unmanned aerial vehicle enables an unmanned aerial vehicle body to keep a horizontal posture.

Description

technical field [0001] The invention specifically relates to a shock-absorbing landing gear for a light-duty rotor UAV, which belongs to the technical field of UAVs. Background technique [0002] In recent years, drone technology has developed by leaps and bounds. Due to its low cost, good maneuverability, strong survivability, and no risk of casualties, UAVs occupy an extremely important position in modern military warfare and have a very broad prospect in the civilian field. [0003] At present, the UAVs used in aerial surveys are special types of UAVs. This kind of UAV has a large load capacity and a long flight time. The main working place is mountainous or high-altitude areas. During the take-off and landing process of the aerial survey UAV, the UAV landing gear is an important device in the process of aircraft take-off and landing. Therefore, there are strict technical requirements for the weight, buffer capacity, installation method and reliability of the landing ge...
