The invention belongs to the field of aviation, and particularly discloses an aircraft control surface lateral folding and unfolding mechanism which comprises an upper control surface and a lower control surface, one side of the lower control surface is fixedly connected with an aircraft, the other side of the lower control surface is hinged to the bottom of the upper control surface through a connecting shaft, and a torsional spring and a locking assembly are arranged between the upper control surface and the lower control surface. The connecting shaft is sleeved with the torsion spring, torsion arms at the two ends of the torsion spring are connected with the upper wing surface and the lower wing surface correspondingly, under the action of the torsion spring, the upper control surface can be rotationally folded or unfolded around the connecting shaft relative to the lower control surface, and after the upper control surface is unfolded relative to the lower control surface, the locking assembly can lock the upper control surface. The control surface can be effectively folded, unfolded and locked, it is guaranteed that the upper control surface keeps relatively static after being unfolded relative to the lower control surface, the unfolding speed is high, locking is firm and reliable, and the structure is simple.

    本发明属于航空领域,具体公开一种飞行器舵面侧向折叠展开机构,包括上舵面和下舵面,下舵面一侧与飞行器固定连接,下舵面另一侧通过连接轴与上舵面底部铰接连接,在上舵面和下舵面之间设置有扭簧和锁紧组件,扭簧套设在连接轴上,扭簧两端的扭转臂分别与上翼面和下翼面连接,在扭簧的作用下,上舵面能够绕连接轴相对下舵面旋转折叠或展开,上舵面相对下舵面展开后,锁紧组件能够锁紧上舵面,本发明飞行器舵面侧向折叠展开机构,能有效折叠、展开、锁紧,保证上舵面相对下舵面展开后保持相对静止,展开速度快,锁紧牢固可靠,且结构简单。
