The invention relates to an unmanned aerial vehicle provided with a parachute device. The unmanned aerial vehicle provided with the parachute device comprises a vehicle body, wherein a control circuit and a power supply device are arranged in the vehicle body, four rotor wings distributed along rectangular angular points are arranged outside the vehicle body, an acceleration sensor and an angle sensor are also arranged inside the vehicle body, the acceleration sensor and the angle sensor are connected with the control circuit, a parachute bin is arranged at the upper side of the vehicle body, a fragile thin film is arranged at the upper part of the parachute bin, a folding parachute is arranged in the parachute bin, an elastic device is arranged at the lower part of the parachute, the elastic device is in a compressed state, an electromagnetic switch used for energy release of the elastic device is arranged, and the control circuit is connected with the electromagnetic switch. The unmanned aerial vehicle provided with the parachute device has the advantages that equipment state is perceived by virtue of the acceleration sensor and the angle sensor, if the vehicle body is detected to be in a falling state, the control circuit drives the elastic device to eject the parachute, and the vehicle body is protected and slowly falls to the ground, so that the loss is avoided.
