The invention belongs to the field of wing structure design, and particularly relates to a connecting structure of a central wing, an outer wing and a supporting rod and a wing. Comprising a central wing connector, an outer wing connector and a supporting rod connector. Two pairs of insertion lugs are arranged on the central wing joint, the central wing joint is connected with the outer wing joint through one pair of insertion lugs, and the central wing joint is connected with the supporting rod joint through the other pair of insertion lugs; according to the invention, the double insertion lugs are designed on one joint, the connection of three large sections of the central wing, the outer wing and the rotor wing supporting rod is realized at one joint in an insertion lug manner, and the simple and convenient disassembly and assembly between the central wing and the rotor wing supporting rod as well as between the central wing and the outer wing are realized; the weight reduction effect is obvious, and the load transfer efficiency is obviously improved. In a complex force transmission connection area, the gluing is used as a main connection mode, and a fastener is used for local assistance to reinforce connection, so that the slippage phenomenon between the central wing and the outer wing is avoided; the number of parts is small, the structure is simple, and manufacturing and assembling are simplified.

    本发明属于机翼结构设计领域,具体涉及一种中央翼、外翼和撑杆的连接结构和机翼。包括中央翼接头、外翼接头和撑杆接头;所述中央翼接头上设置有两对插耳,所述中央翼接头通过一对插耳连接外翼接头,所述中央翼接头通过另一对插耳连接撑杆接头;本发明将双插耳设计在一个接头上,在一个连接处通过插耳方式实现中央翼、外翼和旋翼撑杆三个大部段的连接,实现中央翼和旋翼撑杆之间、中央翼和外翼之间的简便拆装;减重效果明显,传载效率明显提高。在复杂传力连接区,本发明以胶粘作为主要连接方式,局部辅助采用紧固件加强连接,避免了中央翼与外翼之间的滑移现象;零件数量少、结构简单,简化了制造和装配。
