The invention relates to the technical field of aerospace, and discloses an airfoil folding and unfolding mechanism. The mechanism comprises a wing root rotating shaft, an actuator with a telescopic pull rod, a transmission pull rod, a transmission joint and an in-place lock, the folding wing surface is connected with the wing root through a wing root rotating shaft; the actuator is connected withthe transmission pull rod through an opening formed in the wing root; the transmission pull rod is connected with the transmission joint; the transmission joint is arranged on the folding wing surface; a pull rod of the actuator drives a transmission pull rod to move through linear motion; the transmission pull rod drives the transmission connector to move while rotating around the wing root rotating shaft, then the folding wing face is driven to move around the rotating shaft, after the folding wing face rotates in place, the folding wing face is locked through the in-place lock, all wing face unfolding actions are completed, and the transmission pull rod and the transmission connector are completely contained in the wing root through the opening after the folding wing face rotates in place. The unfolding speed and acceleration of the airfoil are flexibly controlled by transmitting tension and thrust along the transmission rod and a certain moment, so that the airfoil is stably unfolded in place without impact.

    本发明涉及航空航天技术领域,公开了一种翼面折叠展开机构。该机构包括翼根转轴、具有可伸缩拉杆的作动器、传动拉杆、传动接头和到位锁,折叠翼面与翼根通过翼根转轴连接,作动器通过翼根上设置的开口与传动拉杆连接,传动拉杆与传动接头连接,传动接头设置在折叠翼面上,作动器的拉杆通过直线运动带动传动拉杆产生运动,传动拉杆在绕翼根转轴转动的同时带动传动接头运动,进而带动折叠翼面绕转轴运动,折叠翼面转动到位后通过到位锁锁定,完成全部翼面展开动作,传动拉杆与传动接头在折叠翼面转动到位后通过开口完全收入翼根内。通过传递沿传动杆的拉力和推力及一定的力矩,灵活控制翼面展开的速度和加速度,实现翼面到位无冲击,平稳展开。
