The invention relates to a wing longitudinal folding mechanism which comprises an inner wing, an outer wing and a driving device fixed to the side close to a fuselage. The inner wing is in shaft connection with the outer wing; the inner wing comprises a main body support frame, an inner wing upper dimensional surface and an inner wing lower dimensional surface; the driving device drives the outer wing, the inner wing upper dimensional surface and the inner wing lower dimensional surface at the same time through a connecting rod assembly, and the outer wing is longitudinally folded to the position between the inner wing upper dimensional surface and the inner wing lower dimensional surface. According to the wing/missile wing folding and unfolding mechanism, the inner wing dimensional surface shares the wing unfolding driving force, a driving source does not need to be additionally configured, the mechanism is simple and reliable, the space utilization rate is high, the transmission efficiency is high, the influence on the aerodynamic configuration is small, and the wing/missile wing folding and unfolding mechanism can be applied to various unmanned aerial vehicles/missiles through modification.

    本发明涉及一种机翼纵向折叠机构,包括内翼、外翼和固定于靠近机身一侧的驱动装置;所述内翼与所述外翼之间为轴连接;所述内翼包括主体支撑架、内翼上维形面和内翼下维形面;所述驱动装置通过连杆组件同时驱动所述外翼、所述内翼上维形面和所述内翼下维形面,且使所述外翼纵向折叠至所述内翼上维形面与所述内翼上维形面之间。本发明,内翼维形面共用机翼展开的驱动力,无需额外配置驱动源,机构简单可靠、空间利用率高、传动效率高,对气动外形影响小,通过改装,可应用于多种无人机/导弹的机翼/弹翼折叠展开机构。
