The utility model relates to the technical field of unmanned aerial vehicles, and discloses an integrated undercarriage of a fire extinguishing unmanned aerial vehicle, which comprises an unmanned aerial vehicle undercarriage, damping mechanisms are fixedly connected to the front part and the rear part of the lower end of the unmanned aerial vehicle undercarriage, and three supporting rods are fixedly connected to the lower ends of the two damping mechanisms. Supporting legs are jointly and fixedly connected between the lower ends of the three supporting rods on the front side and between the lower ends of the three supporting rods on the rear side in a penetrating mode, a fire extinguishing mechanism is fixedly connected to the middle of the lower end of the unmanned aerial vehicle undercarriage, and a bin door is arranged in the middle of the right end of the fire extinguishing mechanism; and a fixing frame is fixedly connected between the upper end of the fire extinguishing mechanism and the frame wall of the unmanned aerial vehicle undercarriage. According to the integrated undercarriage of the fire extinguishing unmanned aerial vehicle, by arranging the damping mechanism and the buffering mechanism, the damping and buffering effects are enhanced, the service life is prolonged, by arranging the fire extinguishing mechanism, fire extinguishing bombs can be freely thrown, the stability of the unmanned aerial vehicle is improved, and the integrated undercarriage is suitable for being widely used.

The invention discloses a coaxial dual-rotor universal aircraft which comprises a cabin, a dual-rotor structure, a rotor driving mechanism and a steering supporting mechanism, the dual-rotor structure comprises a working shaft, an upper rotor and a lower rotor, the working shaft is connected with the top wall of the cabin through a rotary supporting unit and comprises an inner shaft and an outer shaft, the lower rotor is arranged at the top of the outer shaft, and the upper rotor is arranged on the outer shaft. The inner shaft upwards extends out of the outer shaft; the upper rotor wing is arranged at the upper part of the inner shaft; the rotor driving mechanism comprises a first motor, a second motor and a transmission structure which are arranged outside the gearbox, the first motor and the second motor are both in transmission connection with the transmission structure, and the lower end of the inner shaft and the lower end of the outer shaft are both in transmission connection with the transmission structure; the steering supporting mechanism is in transmission connection with the gearbox. Double motors are adopted to control the double rotors, the motors achieve rotation of the double rotors through a transmission structure, the steering supporting mechanism is matched with the rotation supporting unit, universal adjustment of the double rotors can be achieved, the dip angles of the rotors are adjusted, and then flexible flight in the XYZ space is achieved.
