The present invention discloses a dual-axis platform for use in an unmanned aerial vehicle and a tri-axis platform for use in an unmanned aerial vehicle, comprising a machine frame assembly, a transmission assembly and a shooting assembly. The machine frame assembly comprises a first bracket, a second bracket and a third bracket, wherein the shooting assembly is fixed on the first bracket, the first bracket is rotatably arranged with the second bracket, and the second bracket is rotatably arranged with the third bracket. The transmission assembly comprises a first motor and a second motor, wherein the first motor drives the first bracket to rotate about its rotation axis relative to the second bracket, and the second motor drives the second bracket to rotate about its rotation axis relative to the third bracket. The present invention employs the motors, as a motive power, to directly connect to the machine frame assembly of the platform, consumes less energy and saves electrical power; meanwhile the motors have a short action response time, are capable of starting and stopping quickly, or adjusting the magnitude of the rotation speed in a timely manner to adapt for various flying postures of the unmanned aerial vehicles and thereby improving shooting stability of the shooting assembly. |
