Four-rotor wing unmanned aerial vehicle with pneumatic structure

Abstract

The invention discloses a four-rotor wing unmanned aerial vehicle with a pneumatic structure. The four-rotor wing unmanned aerial vehicle with the pneumatic structure comprises a machine body, a front rotor wing, a rear rotor wing, a left rotor wing, a right rotor wing, support arms, and an undercarriage, wherein rotor wing motors are fixed at the outer ends of the support arms, the rotor wings are mounted on the rotating shafts of the rotor wing motors and driven by the rotor wing motors; the machine body comprises a machine cover with a curved surface, and an inner chamber, the support arms are horizontally and fixedly mounted outside the machine body, the curve of the longitudinal section of an upper molded surface of the machine cover is longer than the curve of the longitudinal section of a lower molded surface, and the gravity centre position of the support arm connected to the rear rotor wing is lower than the support arm connected with the front rotor wing. According to the four-rotor wing unmanned aerial vehicle provided by the utility model, through the design of structural improvement on a casing, the casing is enabled to have an upward winged lifting force, and three times of take-off weight can be provided, therefore, a greater carrying capacity and a relatively long endurance can be achieved. Due to the design of vertical height difference of the rear arm and the front arm, the phenomenon of the forward inclination of the machine body caused during the acceleration of the motor on the rear arm can be effectively avoided, and the driving performance is improved.

Description
