The invention provides a folding wing unfolding mechanism. The folding wing unfolding mechanism comprises a shell, side wings, a bottom plate, a rotating unit, an upper limiting unit and a lower limiting unit. The side wings are unfolded through sliding grooves in the left side face and the right side face of the shell, the rotating unit is used for driving the two side wings to be unfolded and folded synchronously through meshed gears, and the unfolding angles of the side wings are displayed through an indicating rod and a protractor. The two upper limiting units are arranged above side wings outside the shell, the two lower limiting units are arranged below the side wings outside the shell, and the upper limiting units and the lower limiting units are used for limiting the side wings from the upper portions and the lower portions of the side wings respectively when the side wings are unfolded. The bottom plate is provided with a hole used for containing the part, extending out of the shell, of the lower limiting unit, and the arc-shaped plates on the two sides of the bottom plate can play a buffering role when the side wings are retracted. The mechanism can ensure that the side wings are accurately unfolded at a set angle and can be accurately unfolded for a long time.

    本发明提供一种折叠翼展开机构,包括:外壳、侧翼、底板、旋转单元、上限位单元和下限位单元。侧翼通过外壳左右侧面的滑槽展开,旋转单元通过设置啮合的齿轮用于带动两个侧翼同步展开和收纳,通过设置指示杆和量角器显示侧翼展开角度;在所述外壳外部侧翼上方设置两个所述上限位单元,在所述外壳外部侧翼下方设置两个所述下限位单元,所述上限位单元和下限位单元用于在侧翼展开时分别从所述侧翼上方和下方对所述侧翼进行限位。底板上设置孔洞用于收纳下限位单元伸出外壳的部分,底板两侧的弧形板可在侧翼收回时起到缓冲作用。本机构可保证侧翼精准展开设定角度并长时间保持精准展开。
