A two-axis cradle for use in an unmanned aerial vehicle, a three-axis cradle for use in an unmanned aerial vehicle, and a multi-rotor aircraft

摘要

The present invention discloses a dual-axis platform for use in an unmanned aerial vehicle, a tri-axis platform for use in an unmanned aerial vehicle and a multi-rotor aerial vehicle, comprising a machine frame assembly, a transmission assembly and a shooting assembly, wherein the machine frame assembly comprises a first bracket, a second bracket and a third bracket; the transmission assembly comprises a first motor and a second motor; the platform further comprises a linkage member with two free ends respectively rotatably arranged at two open ends of the second bracket; the linkage member is fixed on the third bracket via a fastener. In the present invention, the free ends of the linkage member are hingedly arranged on the second bracket to jointly form a parallelogram linkage. When the second bracket rotates a certain angle relative to the third bracket, the linkage member rotates the same angle along with it without affecting the trajectory of the rotation of the second bracket; the linkage member is fixed on the third bracket via a fastener, and the linkage member provides effective support for the second bracket in a vertical direction, thereby increasing the load capacity and rigidity of the second bracket, and effectively reducing the amount of deformation thereof.
