A take-off and landing device for a small unmanned aerial vehicle

Abstract

The invention discloses a take-off and landing device for a small-sized unmanned aerial vehicle. The take-off and landing device for the small-sized unmanned aerial vehicle comprises an external side plate (1), an internal side plate (2), a rear wheel (6), a front wheel (5), a front wheel steering engine (12) and a wheel axle and wheel fork component. The impact on the rear wheel, which is used as a bearing wheel, at the moment of landing is transmitted to a vehicle main structure after passing through landing gear double side plates and a vertical tail connecting piece in sequence so that good shock absorbing effect is realized. Each accessory between the external side plate and the internal side plate is also used as a connecting piece between the steering engine and the front wheel while being used for providing supporting forces to the double side plates; therefore, the effective utilization rate of the structural parts is increased, the additional connecting pieces is reduced in use and a weight reducing effect is also realized. And meanwhile, as lightening holes are punched in strength-rich parts of the rear parts of the side plates, the weight of the structure is effectively reduced. Through adoption of the design method of the wheel axle and wheel fork component, the invention is advantaged in that good strength and good manufacturability are realized, the number of the connecting pieces is greatly reduced and the weight of the take-off and landing wheel fork component is reduced.

Description

technical field [0001] The invention relates to the field of small unmanned aerial vehicle landing gear structure design, in particular to a landing gear for small unmanned aerial vehicles. Background technique [0002] In the design process of UAVs, on the one hand, the landing gear is required to have a light structure, which is specifically reflected in the ingenious structural design, reasonable layout, and appropriate material selection; The impact is specifically manifested in the fact that the overall structure of the landing gear and the joint between the fork and the axle can withstand the impact load of the aircraft and the ground when it lands. In order to meet the functional requirements of the UAV's landing gear and the strict weight design index, in the overall design process of landing transposition, it is necessary to ensure the strength and stiffness of the landing gear, and strive to achieve a simple structure of the landing gear , perfect performance, and...

Problems solved by technology

However, since the fork and the axle are made of different materials, they cannot be welded into one body, so additional connecting pieces must be used to make them fixedly connected.
