The invention discloses a variable-elongation wing structure which comprises a wing shell, a transmission assembly and a locking assembly, a composite corrugated skin is fixedly mounted in the middle of the wing shell, a wing rib is mounted in the wing shell, a mounting strip is mounted on the inner side of the wing rib, and a fixing plate is fixedly mounted in the middle of the mounting strip; and a hydraulic cylinder is mounted on the rear side of the front end of the fixed plate. The invention belongs to the technical field of wing structures, and aims to solve the problems that in the prior art, a driving system is too large in mass and high in complexity, and meanwhile, a wing cannot be locked in an auxiliary mode according to the stretching length in the stretching process. According to the technical effects, the extension change of the whole wing structure is achieved in a mode that the transmission assembly conducts power transmission, the complexity is reduced, meanwhile, the auxiliary locking function is achieved, and the phenomenon of displacement deviation of the adjusted extension due to the phenomena that the internal oil pressure of the hydraulic cylinder is unstable and the like is effectively prevented.

    本发明公开了一种变展长机翼结构,包括:机翼外壳、传动组件和锁定组件,所述机翼外壳的中部固定安装有复合式波纹蒙皮,且机翼外壳的内部安装有翼肋,所述翼肋的内侧安装有安装条,且安装条的中部固定安装有固定板,所述固定板的前端后侧安装有液压缸。本发明属于机翼结构技术领域,本发明的目的在于解决现有技术中驱动系统质量太大,复杂度较高,同时,在伸展过程中无法根据伸展的长度对机翼进行辅助锁定的问题。达到的技术效果为:传动组件进行动力传递的方式实现整个机翼结构的展长变化,降低复杂程度,同时,具有辅助锁定功能,有效防止液压缸因内部油压不稳等现象而导致调节后的展长发生位移偏差的现象。
