[0002] Landing gear is a support frame used on UAVs. Fixed-wing UAVs are small UAVs in the shape of airliners. The landing gear is a landing gear with tires. When flying in the air The landing gear will be folded into the inside of the UAV and put down when it lands; however, the traditional landing gear does not have an orientation function when it is folded. On the one hand, it will cause a large load on the coupling shaft and gears, and on the other hand, it is easy to open the range. Crossing the vertical line will affect the normal landing of the UAV, which is not conducive to use. Secondly, the cushioning and shock absorption effect is poor, and it will have a large impact on the ground when it lands, which will reduce the service life of the UAV.

The invention discloses an elastically supported landing gear for a fixed-wing unmanned aerial vehicle based on rack transmission, which includes the unmanned aerial vehicle, a main rod of the landing gear and an electric telescopic rod. A connecting gear is fixedly installed on the top of the main rod of the landing gear. The connecting gear is movably connected with the UAV through a rotating shaft, and a fixed slider is fixedly installed at the upper position inside the UAV, and a rack is provided at the rear of the fixed slider. The telescopic rod is fixedly connected to one end of the rack, and a connecting fixture is arranged between the telescopic rod of the electric telescopic rod and the rack. A fixed-wing unmanned aerial vehicle according to the present invention is based on the rack-driven elastic support landing gear, which can play a role in orientation, reduce the bearing load of the rotating shaft, and can also avoid the phenomenon that the landing gear crosses the vertical line when it is opened. At the same time, it also has excellent shock absorption and buffering effect, which has an excellent protection effect on drones.
Description
technical field [0001] The invention relates to the field of landing gear, in particular to an elastically supported landing gear for a fixed-wing unmanned aerial vehicle based on rack drive. Background technique [0002] The landing gear is a frame used for support on the drone. The fixed-wing drone is a small drone in the shape of a passenger plane. Its landing gear is a landing gear with tires. When flying in the air The landing gear will be folded inside the UAV and put down when it lands; however, the traditional landing gear does not have an orientation function when it is folded. On the one hand, it causes a large load on the coupling shaft and gears, and on the other hand, it is easy to open the range Crossing the vertical line will affect the normal landing of the UAV, which is not conducive to use. Secondly, the cushioning and shock absorption effect is poor, and it will have a large impact on the ground when it lands, resulting in a reduction in the service life o...
