The invention provides an embedded folding wing mechanism which comprises a wing piece or a rudder piece, a seat body, a torsional spring, a screw pin, a plate spring and a cylindrical pin, and the seat body is connected with an aircraft cabin; the wing pieces or the rudder pieces are hinged to the base body through cylindrical pins, rotate around the axes of the cylindrical pins and retract intoaxial grooves in the outer wall of the aircraft cabin body or are unfolded in the radial direction of the aircraft cabin body. One end of the torsional spring is connected with the seat body through ascrew pin, and the other end is connected with a cylindrical pin to provide power for outward rotation of the wing or rudder from the aircraft cabin; the plate spring is installed on the seat body, the plate spring is located between the wing piece or the rudder piece and the seat body when the wing piece or the rudder piece retracts into the outer wall of the aircraft cabin body, the wing pieceor the rudder piece extrudes the warping face of the plate spring to deform, the plate spring rebounds after the wing piece or the rudder piece is unfolded and abuts against the side face of the wingpiece or the rudder piece, and in-place unfolding is guaranteed. A longitudinal folding scheme is adopted, the structure is exquisite, the response speed is high, and good strength, rigidity, shock resistance and installation precision are achieved.

    本发明提供了一种嵌入式折叠翼机构,包括翼片或舵片、座体、扭簧、螺钉销、板簧和圆柱销,座体与飞行器舱体连接;翼片或舵片通过圆柱销铰接在座体上,翼片或舵片绕圆柱销轴线转动,缩入飞行器舱体外壁的轴向槽内,或沿飞行器舱体径向展开;扭簧一端通过螺钉销连接座体,另一端连接圆柱销,提供翼片或舵片从飞行器舱体向外转动的动力;板簧安装在座体上,翼片或舵片缩入飞行器舱体外壁时板簧位于翼片或舵片与座体之间,翼片或舵片挤压板簧翘曲面使其变形,翼片或舵片展开后板簧回弹,顶紧翼片或舵片的侧面,保证翼片或舵片展开到位。本发明采用纵向折叠方案,结构精巧,响应速度快,有较好的强度、刚度、抗震能力及较好的安装精度。
