The invention discloses a folding wing structure of an unmanned aerial vehicle, which comprises a rotating shaft embedded in a vehicle body, wherein a lower wing elastic sheet and an upper wing elastic sheet are mounted in an inner cavity of the rotating shaft from bottom to top, a first locking block and a second locking block are respectively arranged at the free ends of the lower wing elastic sheet and the upper wing elastic sheet, the first locking block and the second locking block are respectively matched with a first notch and a second notch which are formed in the rotating shaft, the outer side of the rotating shaft is sequentially sleeved with a lower wing and an upper wing from bottom to top, the upper surface of the lower wing and the lower surface of the upper wing are each provided with a groove, the two grooves are oppositely formed to form a torsional spring groove, a torsional spring is arranged in the torsional spring groove, and the upper inner sides of the lower wingand the upper wing are provided with a first locking groove and a second locking groove correspondingly; and the outer side of the rotating shaft is further sleeved with a roller bearing, a baffle isinstalled at the top of the rotating shaft, and the roller bearing is located between the upper wing and the baffle. The processing cost of the unmanned aerial vehicle is reduced, the folding wing structure is insensitive to the structural size, and the folding wing structure can adapt to a more miniaturized barrel-shooting unmanned aerial vehicle.

    本发明公开了一种无人机折叠翼结构,包括镶嵌在机身上的转轴,转轴的内腔中从下至上安装有下机翼弹片和上机翼弹片,下机翼弹片和上机翼弹片的自由端分别设置有第一锁紧块和第二锁紧块,第一锁紧块和第二锁紧块分别与设置在转轴上的第一缺口和第二缺口配合,转轴的外侧从下至上依次套设有下机翼和上机翼,下机翼的上表面和上机翼的下表面分别均设置有凹槽,两个凹槽相对设置形成扭簧槽,扭簧槽中设置有扭簧,下机翼和上机翼上内侧分别设置有第一锁紧槽和第二锁紧槽;转轴的外侧还套设有滚柱轴承,转轴的顶部安装有挡板,且滚柱轴承位于上机翼与挡板之间。本发明降低了无人机的加工成本对结构尺寸不敏感,可以适应更加小型化的筒射无人机。
