The invention discloses an unmanned aerial vehicle parachute automatic release unit. The unmanned aerial vehicle parachute automatic release unit structurally comprises a support rack, wing cabins, anti-collision racks, blades, a parachute automatic release unit body, a unmanned aerial vehicle body and a camera and is characterized in that the support rack is welded to the bottom of the unmanned aerial vehicle body and connected with the ground, the wing cabins are arranged in the middles of the anti-collision racks, arranged on the outer side of the unmanned aerial vehicle body and electrically connected with the unmanned aerial vehicle body, the anti-collision racks are fixed outside the wing cabins and fixedly connected with the unmanned aerial vehicle body to form an integral structure, the blades are arranged on the upper portions of the wing cabins and rotatably connected with the same, and the parachute automatic release unit body is mounted at the top of the unmanned aerial vehicle body and movably connected with the same. The unmanned aerial vehicle parachute automatic release unit has the advantages that when an unmanned aerial vehicle loses balance and stops powered flight, an internal parachute can be popped up through a wind power transmission structure, the unmanned aerial vehicle can safely land, a protective shell mounted inside the release unit can reduce impact force on the unmanned aerial vehicle body, the parachute can be automatically retracted when the unmanned aerial vehicle is recharged and used, and recycling, time saving and use convenience are achieved.
