The invention relates to the technical field of aircrafts, in particular to a motor arm and an aircraft, and the motor arm comprises a shell and a plurality of battery modules. The shell comprises a truss structure and a skin, a cavity is defined by the truss structure, the truss structure is covered with the skin, and the skin at least shields part of the cavity. All the battery modules are arranged in the cavity, and all the battery modules are sequentially arranged in the length direction of the shell. According to the motor arm, the truss structure is adopted in the shell, the structure is simple, the force transmission path is clear, the battery modules can be arranged within the truss range, the arrangement number of the battery modules is greatly increased, the structural strength of the shell is improved, and the weight of the shell is reduced.
本申请涉及飞行器技术领域,尤其涉及一种电机臂及飞行器,电机臂包括壳体和多个电池模组。壳体包括桁架结构和蒙皮,所述桁架结构围合形成空腔,所述蒙皮覆盖于所述桁架结构上,所述蒙皮至少遮蔽部分所述空腔。各所述电池模组均设置于所述空腔内,且各所述电池模组沿所述壳体的长度方向依次布置。本申请电机臂的壳体采用了桁架结构,构造简单、传力路径明确,在桁架范围内均可布置电池模组,极大增加了电池模组布置数量,且提高了壳体的结构强度,减小了壳体的重量。
