The invention discloses a multi-rotor unmanned aerial vehicle arm connecting structure, relates to the technical field of unmanned aerial vehicle instruments, and provides the following scheme that the multi-rotor unmanned aerial vehicle arm connecting structure comprises a vehicle arm and a vehicle body which are oppositely arranged, and a vehicle arm right lock catch assembly and a vehicle arm left lock catch which are arranged on the outer surface of the vehicle arm. A lock catch fixing piece arranged on the surface of the outer ring of the vehicle arm in a sleeving mode is arranged between the right vehicle arm lock catch assembly and the left vehicle arm lock catch assembly. According to the technical scheme, by means of the principle that an inclined plane is used for eliminating gaps, the arms are inserted into the fuselage, wedge-shaped grooves in the ends of the arms are matched with wedge-shaped bosses of the fuselage, and the redundant freedom degree in the symmetry process is eliminated; at the moment, the two lock catches which are symmetrical left and right and provided with the elastic reset spring bolts are pulled, so that the gap between the vehicle arm and the vehicle body is eliminated, and the vehicle arm is rotated to be horizontal and automatically locked; the relative positions of the vehicle arms and the vehicle body are fixed; and meanwhile, the locking and anti-backlash functions are achieved, so that the connection between the unmanned aerial vehicle arm and the vehicle body is more reliable.

    本发明公开了一种多旋翼无人机机臂连接结构,本发明涉及无人机器械技术领域,现提出如下方案,包括:相向布置的机臂和机身,以及设置在机臂外表面上的机臂右锁扣组件和机臂左锁扣。其中,所述机臂右锁扣组件和机臂左锁扣之间设置有套在机臂外圈表面上的锁扣固定件。本发明技术方案中利用斜面消隙的原理,借助机臂与机身对插,机臂端的楔形凹槽与机身的楔形凸台配合,消除对称过程中的多余自由度;此时扳动带弹性复位的锁舌的左右对称的两个锁扣,借此消除机臂与机身的间隙,旋至水平则到位并自动锁止;完成机臂与机身的相对位置固定;进而解决无人机机臂拆卸的便捷性问题,同时具有锁止、消隙功能,使无人机机臂与机身的连接更加可靠。
