The invention discloses an automatic parachute falling mechanism of an unmanned aerial vehicle. The automatic parachute falling mechanism of the unmanned aerial vehicle is used for resolving the technical problem that an existing automatic parachute separation mechanism of the unmanned aerial vehicle is poor in practicability. According to the technical scheme, the automatic parachute falling mechanism of the unmanned aerial vehicle comprises a parachute belt, a parachute belt shaft, an upper falling joint, a lower falling joint, a piston, a ball, a sucking rod, a spring, an electromagnet installation frame, a coil, a magnet, an opening pin and a screw. When a parachute of the unmanned aerial vehicle is landed, the magnet enables the sucking rod to move leftwards and rightwards to press the spring, then the piston is pushed to move rightwards, the ball falls into an arc groove of the piston, restraint to the ball by the upper falling joint and the lower falling joint is eliminated, an unlocking motion is finished, and the upper falling joint and the lower falling joint are separated. Automatic separation of the parachute and the unmanned aerial vehicle is finished, and the problem that when the parachute of the unmanned aerial vehicle is landed, the posture of the recovered parachute is changed and the parachute is opened when recovered due to wind, so that unlocking can not be achieved is resolved. Meanwhile, the problem that in the parachute opening process in the air, due to posture changes of the unmanned aerial vehicle and a parachute pack, the parachute belt may have no restraint force, and the parachute is thrown in wrong actions is avoided.
