The invention discloses a vehicle body of a double-rotor unmanned aerial vehicle. The vehicle body comprises an integral vehicle body framework, support rods and an undercarriage, wherein the integralvehicle body framework is formed by pipe fittings and comprises a top frame, reducer mounting frames, a bottom frame, end inclined struts and side supports, the reducer mounting frames are correspondingly arranged at two ends of the top frame, the bottom frame is longitudinally separated from the top frame, the end inclined struts are used for correspondingly connecting to the end part of the bottom frame and the reducer mounting frames, and the side supports are used for correspondingly connecting and supporting the frame sides of the top frame and the wide sides of the bottom frame; the vehicle body framework is integrally and internally penetrated and is filled with high pressure gas, an air pressure sensor for sensing the pressure of the high pressure gas is arranged in the vehicle body framework; and the support rods are distributed on two sides of the vehicle body framework, and the upper and lower ends of the support rods are respectively fixedly connected with the frame sidesof the bottom frame and the frame sides of the top frame. The vehicle body framework is integrally of a truss structure and partially of a triangle structure and is firm and reliable. By virtue of theenhancement of inclined strut pipes and steel channels, the integral strength and stiffness of the vehicle body are increased; and the weight of the vehicle body is reduced, and the cost is saved.
