Abstract

An all-electric steering anti-shock device for the front landing gear of an unmanned aerial vehicle belongs to the technical field of unmanned aerial vehicles, and aims to solve the problem of lateral deviation when the aircraft is sliding. An all-electric steering anti-shock device for the front landing gear of an unmanned aerial vehicle of the present invention comprises: a fixed pillar, which is a hollow structure; a steering drive module integrally fixed inside the fixed pillar; an upper end and the drive module A shafting module connected; a rotating strut fixedly connected to the lower end of the shafting module; and an electromagnetic damper connected between the fixed strut and the rotating strut; the onboard computer adjusts the motor in the steering drive module according to the information collected by the steering drive module output and the output of the electromagnetic damper. The invention can realize the functions of skating deviation correction, swing reduction and centering. The system is simple in structure, low in cost and easy to maintain; compact and reasonable in layout, easy to retract; complete in function and high in reliability. It can be widely used in various small and medium-sized UAVs.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to an all-electric steering swing reduction device for the front landing gear of an unmanned aerial vehicle. Background technique [0002] With the widespread application of drones in military and civilian fields, their advantages such as low cost, high safety, and short development cycle have become increasingly prominent. However, while drones for various purposes continue to emerge, recycling accidents also continue to occur. According to statistics, most UAV accidents occur during the take-off and landing process. The safe take-off and landing of UAVs is a difficult and hot spot in the development of UAVs. Among them, the design of landing gear is a key area that people pay attention to. [0003] Most of the landing gear has a front three-point layout. When the aircraft taxis to a certain speed, the front wheels will have a violent sideways swing awa...
