Abstract

The invention belongs to the technical field of landing gear, and in particular relates to a UAV with a retractable landing gear, which includes a UAV body, a landing mechanism, an adjustment mechanism, a front wheel, and a rear wheel. The landing mechanism can be put down or recovered; the landing bar can be pulled up from the vertical state and recovered to a certain extent, which can reduce the wind resistance of the drone during flight. Compared with the unmanned aerial vehicle without the function of retracting the landing gear, the unmanned aerial vehicle of the present invention will have better flight efficiency. In addition, compared with the unmanned aerial vehicle with the function of retracting the landing gear, the UAV of the present invention only needs one servo motor to retract the landing gear to make the three landing gears move simultaneously, reducing the need for traditional unmanned aerial vehicles. The complexity of the control of two servo motors. The retraction of the three landing bars of the present invention does not use the hydraulic system in the traditional drone, which greatly simplifies the structure and reduces the manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of landing gear, in particular to an unmanned aerial vehicle with retractable landing gear. Background technique [0002] At present, fixed-wing UAVs have been widely used in the commercial field, and compared with military fixed-wing UAVs, fixed-wing UAVs for commercial use are small in size and low in cost. However, in order to save costs for commercial fixed-wing UAVs, the landing gear of some commercial fixed-wing UAVs cannot be freely retractable. The landing gear that cannot be retracted freely can easily cause relatively large wind resistance during the flight of the fixed-wing UAV, which affects the flight of the fixed-wing UAV to a certain extent. For the landing gear with freely retractable function, the front landing gear and the rear landing gear are controlled by two servo motors, and some also need to use the hydraulic system to control the retraction and retraction of the landing gear. The a...
