The invention relates to the field of aircrafts, in particular to an aircraft rotor wing support arm folding mechanism and an aircraft rotor wing support arm. The second support is provided with a second abutting surface; the first support and the second support are hinged through a rotating shaft and locked through a lock pin to form a folded state and an unfolded state, and in the unfolded state, the first abutting face abuts against the second abutting face; first connecting lugs are arranged on the two sides of the first abutting face, second connecting lugs are arranged on the two sides of the second abutting face, and the first connecting lugs are used for being connected with the second connecting lugs in an abutting mode and matched with the second connecting lugs to install the rotating shaft and the lock pin; the abutting face of the first connecting lug and the second connecting lug deviates from the center of the first abutting face and is close to the bottom of the first abutting face. The folding mechanism is ingenious in design, the stress performance and the fatigue performance of the folding mechanism can be improved, and the folding mechanism has remarkable popularization significance.

    本发明涉及飞行器领域,具体涉及一种飞行器旋翼支臂折叠机构及飞行器旋翼支臂,其中折叠机构包括第一支座,具有第一抵接面;第二支座,具有第二抵接面;所述第一支座与所述第二支座通过旋转轴铰接并通过锁销锁定,以形成折叠状态与展开状态,在所述展开状态,所述第一抵接面与所述第二抵接面抵接;所述第一抵接面两侧设置有第一连接耳,所述第二抵接面两侧设置有第二连接耳,所述第一连接耳用于与所述第二连接耳抵接并配合以安装所述旋转轴与所述锁销;所述第一连接耳与所述第二连接耳的抵接面偏离于所述第一抵接面的中心且靠近所述第一抵接面的底部。本发明设计巧妙,可以改善折叠机构的受力性能和疲劳性能,具有显著的推广意义。
