UAV (Unmanned Aerial Vehicle) arm folding mechanism

Abstract

The invention discloses a UAV (Unmanned Aerial Vehicle) arm folding mechanism. The UAV arm folding mechanism comprises a UAV arm connection base and a UAV arm folding base arranged on a UAV arm, wherein one end of the UAV arm folding base is hinged to the UAV arm connection base; a folding mechanism is arranged on the UAV arm connection base; the folding mechanism is movably connected with the other end of the UAV arm folding base; the folding mechanism comprises an outer handle and an inner handle; one end of the inner handle is hinged to the UAV arm connection base; the other end of the inner handle is provided with an outer handle rotation shaft in a sleeved manner; one end of the outer handle is hinged to the outer handle rotation shaft; the other end of the outer handle is provided with a connection part which is movably connected with the UAV arm folding base; and the inner handle is further provided with a locking structure for locking the inner handle. The UAV arm folding mechanism is convenient for operation; double-locking is realized; and furthermore, an elastic component is arranged between the two metal components, so that a clearance between the metal components is eliminated; the stability is improved; and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of arm folding mechanisms, and in particular relates to an arm folding mechanism of an unmanned aerial vehicle. Background technique [0002] Unmanned aerial vehicle (unmanned aircraft), which has the advantages of flexible maneuverability, quick response, unmanned flight, and low operation requirements. It is loaded with multiple types of sensors, such as cameras, to realize real-time image transmission. Gaocheng area Detection and other functions are widely used in firefighting, military, transportation, police, exploration and meteorological fields to achieve cruise shooting and monitoring of designated areas. At present, most UAVs are multi-axis UAVs, such as four-axis, six-axis, etc., because the arm is set radially outward relative to the fuselage, the volume is large, and the transportation is inconvenient. At the same time, the structure of the arm may be damaged during transportation. During the co...
