The invention discloses a telescopic vehicle arm and a vehicle arm telescopic unmanned aerial vehicle, and belongs to the field of unmanned aerial vehicles, the telescopic vehicle arm comprises a large vehicle arm and a small vehicle arm, the large vehicle arm is of a hollow structure, and at least one limiting hole is formed in each of the root side wall and the tip side wall of the large vehiclearm; the root of the small arm is slidably inserted into the large arm; elastic pieces are fixed to the roots of the small vehicle arms, limiting protrusions are fixed to the other ends of the elastic pieces, and the elastic pieces provide elastic force for enabling the limiting protrusions to be embedded into the limiting holes so as to limit the positions of the small vehicle arms. The side wall of the small arm is movably sleeved with a fastening sleeve, and when the inner side wall of the fastening sleeve is arranged on the side wall of the tip of the large arm in a sleeving mode, the tipof the large arm contracts to fix the small arm. The unmanned aerial vehicle with the telescopic vehicle arms comprises the telescopic vehicle arms. The telescopic aircraft arm is reasonable in structural design, through cooperative use of the elastic pieces, the limiting holes, the limiting protrusions and the fastening sleeves, the aircraft arm body can stretch out, draw back and be locked, andthe use requirements for transportation, storage and narrow and small space flight are met.

    本发明公开了一种可伸缩机臂及机臂可伸缩无人机,属于无人机领域,其中可伸缩机臂包括大机臂和小机臂,大机臂为中空结构,大机臂的根部侧壁和梢部侧壁均设置有至少一个限位孔;小机臂的根部可滑动的承插在大机臂内;小机臂根部固定有弹片,弹片另一端固定有限位凸起,弹片提供使限位凸起嵌入限位孔中的弹力以限制小机臂的位置;小机臂的侧壁上可活动地套设有紧固套,紧固套的内侧壁配置为套设在大机臂的梢部侧壁上时,使大机臂的梢部收缩以固定小机臂。其中机臂可伸缩无人机包括有上述的可伸缩机臂。本发明结构设计合理,通过弹片、限位孔和限位凸起以及紧固套的配合使用,使机臂能够伸缩并锁定,满足运输、存储和窄小空间飞行使用要求。
