Unmanned aerial vehicle with foldable landing gear

Abstract

The invention belongs to the field of unmanned aerial vehicles, and particularly relates to an unmanned aerial vehicle with a foldable landing gear. The unmanned aerial vehicle with the foldable landing gear comprises an engine body, a front wheel mechanism, a first rear wheel mechanism and a rack mechanism, and the engine body is an existing unmanned aerial vehicle body with a fixed wing; meanwhile, when the unmanned aerial vehicle lands, the front wheel mechanism, the first rear wheel mechanism and a second rear wheel mechanism have a certain buffering function; the steering engine is proneto being damaged under attack due to high rotating speed of a part of gear parts in the steering engine in the working process; and therefore, the buffering function of the front wheel mechanism, thefirst rear wheel mechanism and the second rear wheel mechanism can avoid the occurrence of a phenomenon of broken teeth of high-speed gears in the steering engine caused by the attack of the ground and sliding wheels when the unmanned aerial vehicle lands, so that a driving device on the unmanned aerial vehicle is ensured not to be damaged, and the service life of the unmanned aerial vehicle is furthest prolonged.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with foldable landing gear. Background technique [0002] At present, there are two types of traditional drones, one is unmanned drones with landing gear, and the other is unmanned drones without landing gear; the landing gear on drones with landing gear rarely has a stacking function. UAVs that do not have a stackable landing gear have a large wind resistance during flight, which affects the range; even if some UAVs have a stackable landing gear, it will increase infinitely due to the complexity of the control method of the landing gear. Man-machine research and development and production costs; traditional UAVs with landing gear generally have two control methods for the landing gear: one is to control the hydraulic pump installed on the body through the motor, and then control the three landing gears through hydraulic pressure. The other is t...

[0002] At present, there are two types of traditional drones, one is unmanned drones with landing gear, and the other is unmanned drones without landing gear; the landing gear on drones with landing gear rarely has a stacking function. UAVs that do not have a stackable landing gear have a large wind resistance during flight, which affects the range; even if some UAVs have a stackable landing gear, it will increase infinitely due to the complexity of the control method of the landing gear. Man-machine research and development and production costs; traditional UAVs with landing gear generally have two control methods for the landing gear: one is to control the hydraulic pump installed on the body through the motor, and then control the three landing gears through hydraulic pressure. The other is to control the folding of the three landing gears through at least two servo motors; this traditional way of stacking the landing gear also increases the R&D and production costs of the UAV, thus affecting the UAV being used. The progress of widespread application, which in turn affects the economic benefits of related enterprises
