The invention discloses an unmanned aerial vehicle capable of being prevented from being crashed. The unmanned aerial vehicle comprises a vehicle body. A processing unit and an engine are arranged inside the vehicle body. The processing unit is electrically connected with the engine. A rotor wing is arranged on the vehicle body. A rotating shaft is arranged inside the vehicle body. A groove is formed in the end, close to the rotor wing, of the rotating shaft. The rotor wing is provided with a connecting portion. The connecting portion is inserted into the groove of the rotating shaft and is in interference fit with the rotating shaft. The other end of the rotating shaft is in transmission connection with the engine. An upper medicine bag and a lower medicine bag are arranged inside the groove of the rotating shaft. A folded and compressed parachute is arranged between the upper medicine bag and the lower medicine bag. The parachute is connected with the inner wall of the groove through a line. A first trigger with the sharp bottom is arranged below the parachute. A partition plate is arranged between the first trigger and the lower medicine bag. A second trigger is arranged besides the upper medicine bag. The second trigger is electrically connected with the processing unit. An acceleration sensor is further arranged inside the vehicle body. The acceleration sensor is electrically connected with the processing unit. A parachute system is additionally arranged on the unmanned aerial vehicle, so that the unmanned aerial vehicle is protected against a crash.
