The invention discloses a wing unfolding mechanism using a torsional spring. The wing unfolding mechanism comprises a mounting support, a limiting sleeve, a shaft sleeve, a rotating shaft, the torsional spring, a bearing for the shaft sleeve and a bearing for the rotating shaft, the wing unfolding mechanism is mounted at the lower part of the aircraft body, and two groups of wings of the aircraft are stacked up and down and are connected with the aircraft body through the wing unfolding mechanism; in a storage and transportation state, the two groups of wings are folded to the lower part of the aircraft body through the wing unfolding mechanism and are parallel to the axis of the aircraft body, and when the wings are unfolded, the two groups of wings reversely rotate under the action of the wing unfolding mechanism and are locked by the wing unfolding mechanism after being unfolded in place. The whole structure is compact, synchronous unfolding of the two wings is achieved through one torsion spring, the whole weight is light, the occupied space in the aircraft is small, and the limiting position is accurate and reliable.
本发明公开了一种使用扭簧的机翼展开机构,包括安装支座、限位套、轴套、转轴、扭簧、轴套用轴承、转轴用轴承;机翼展开机构安装在飞行器机身下部,飞行器的两组机翼上下层叠,通过机翼展开机构与飞行器机身相连;在贮存运输状态时,两组机翼通过机翼展开机构折叠至飞行器机身下部并与机身轴线平行,机翼展开时,在机翼展开机构的作用下,两组机翼反向转动,展开到位后,由机翼展开机构锁定。本发明整体结构紧凑,使用一个扭簧实现了对两个机翼的同步展开,整体重量轻,占用机内空间小,限位位置准确可靠。
