The invention discloses a main wing tilting and folding mechanism for supporting multi-mode variant flight of an aircraft. The main wing tilting and folding mechanism comprises a main bearing plate in a fuselage, a driving mechanism and a central wing, wherein the driving mechanism and the central wing are mounted on the main bearing plate in the fuselage; the driving mechanism comprises a transmission belt mechanism, a driving support arm and two driving rod groups; the transmission belt mechanism is mounted on a main bearing plate in the machine body; the driving support arm is fixed on a main bearing plate in the machine body in a sliding manner and is driven to move back and forth through a transmission belt mechanism; two ends of the driving rod group are respectively hinged with one side of the driving support arm and the corresponding outer wing; the outer wing is connected with the central wing through a crossed roller bearing; in the process that the transmission belt mechanism drives the driving supporting arms to move front and back, the driving rod sets are synchronously driven to move front and back, and therefore the outer wings are driven to rotate around the central wing with the crossed roller bearing as the support. The tilting wing unmanned aerial vehicle has enough high strength, rigidity and stability, and switching among multiple flight modes of the tilting wing unmanned aerial vehicle can be achieved.

    本发明公开了一种支持飞行器多模态变体飞行的主机翼倾转折叠机构,包括机身内主承力板以及安装在机身内主承力板上的驱动机构和中央翼;所述的驱动机构包括传动带机构、驱动支臂和两个驱动杆组;所述的传动带机构安装在机身内主承力板上;所述的驱动支臂滑动固定在机身内主承力板上,并通过传动带机构驱动前后运动;所述驱动杆组的两端分别与驱动支臂的一侧以及对应的外翼铰接;所述的外翼通过交叉滚子轴承与中央翼连接;传动带机构带动驱动支臂前后运动的过程中,同步带动驱动杆组的前后运动,从而带动外翼以交叉滚子轴承为依托绕中央翼进行转动。本发明具备足够高的强度、刚度与稳定性,能够实现倾转机翼无人机多个飞行模态之间的切换。
