DUAL-AXIS BALL HEAD FOR USE IN UNMANNED AERIAL VEHICLE, TRIPLE-AXIS BALL HEAD FOR USE IN UNMANNED AERIAL VEHICLE, AND MULTI-ROTOR AERIAL VEHICLE.

摘要

A dual-axis ball head for use in an unmanned aerial vehicle, a triple-axis ball head for use in the unmanned aerial vehicle, and a multi-rotor aerial vehicle, comprising a machine frame component, a transmission component, and a photographing component. The machine frame component comprises a first frame bracket (2), a second frame bracket (2), and a third frame bracket (6). The transmission component comprises a first motor (3) and a second motor (5), and also comprises a connecting rod (12). Two free ends of the connecting rod (12) respectively are rotatably arranged on two open ends of the second frame bracket (4). The connecting rod (12) is fixed onto the third frame bracket (6) via a fastener (13). By hingedly arranging the free ends of the connecting rod (12) onto the second frame bracket (4), both together constitute a parallel quadrilateral connecting rod, when the second frame bracket (4) rotate for a certain number of degrees in relation to the third frame bracket (6), the connecting rod (12) moves in tandem for same number of degrees, a rotation track of the second frame bracket (4) is thus not affected. The connecting rod (12) is fixed via the fastener (13) onto the third frame bracket (6), and the connecting rod (12) provides same with effective support in the vertical direction, thus improving the load capacity and stiffness of the second frame bracket (4), and effectively reducing the degree of distention thereof.
