Vertical undercarriage of unmanned aerial vehicle

Abstract

The invention discloses a vertical undercarriage of an unmanned aerial vehicle. The vertical undercarriage comprises a connecting frame and N supporting assemblies evenly arranged on the lower end face of the connecting frame in the circumferential direction. Each supporting assembly comprises an inner cylinder, an outer cylinder, M supporting legs and M conduction rods corresponding to the supporting legs in a one-to-one mode. During work, the lower ends of the outer cylinders firstly make contact with the ground, the outer cylinders move upwards in the vertical direction along the axis of the inner cylinders under the compression of the gravity of the unmanned aerial vehicle, so that the conduction rods open the supporting legs, and after all the supporting legs make contact with the ground, the undercarriage is supported, and the unmanned aerial vehicle lands stably. The vertical undercarriage is simple in structure and convenient to carry, the unmanned aerial vehicle can be protected against turnover during landing, and damage caused by turnover of the unmanned aerial vehicle is reduced.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicle landing gear, in particular to a vertical landing gear of an unmanned aerial vehicle. Background technique [0002] Since the advent of UAV technology, it has been widely used in municipal, military and other fields. Due to the small size of UAV, it is not easy to find, and can be controlled. It is widely used in reconnaissance, high-altitude shooting, and UAV spraying chemical substances. However, when using a drone, the drone cannot be parked directly on the ground, and landing gear needs to be installed at the bottom of the drone. [0003] The traditional UAV landing gear is generally several outrigger-like structures. Although the UAV can be parked on the ground, due to the different skills of the users, the stability of this type of landing gear is not good, making the UAV It tends to tip over when parked and needs improvement.
