The invention relates to the technical field of unmanned aerial vehicles, in particular to a large-load multi-rotor unmanned aerial vehicle which comprises a vehicle body, a battery module and an undercarriage. The fuselage comprises a central frame and arms, the arms are circumferentially and uniformly arranged around the central frame at intervals, and power parts for providing flight power for the unmanned aerial vehicle are mounted on the arms; every two adjacent machine arms are connected through a connecting arm, so that a large torsion-resistant closed chamber is formed on the outer side. Due to the integral structure of the fuselage, the power distribution is relatively uniform, and the flight balance, stability and high efficiency of the unmanned aerial vehicle can be better guaranteed. In addition, the reaction torque generated by the flight motor can be transmitted through a large anti-torque closed chamber formed by the vehicle arms and the connecting arms to be mutually counteracted; and reaction torque generated due to asymmetry of the rotating speed of the flight motor is mutually counteracted due to transmission of a small anti-torque closed chamber formed by the central rack, so that the reaction torque existing in the flight process is better eliminated, and the flight balance and stability of the unmanned aerial vehicle are further guaranteed.

    本申请涉及无人机技术领域,尤其是涉及一种大载重多旋翼无人机,包括机身、电池模组以及起落架;所述机身包括中央机架和机臂,机臂绕中央机架呈周向均匀间隔布置,且机臂上安装有为无人机提供飞行动力的动力件;相邻两个机臂之间通过连接臂进行连接,以在外侧形成一个大抗扭闭室。由于机身的整体结构、动力分布的比较均匀,能够更好的保障无人机的飞行平衡性、稳定性、高效性。另外,飞行电机所产生的反扭矩,能够通过机臂、连接臂所形成的大抗扭闭室传递相互抵消;而因飞行电机转速不对称所产生的反扭矩,则由于中央机架所形成的小抗扭闭室传递相互抵消,以更好的消除飞行过程中所存在的反扭矩,以进一步保障无人机的飞行平衡行和稳定性。
