The invention discloses a constant-speed telescopic structure applied to a variable-sweepback aircraft. The constant-speed telescopic structure comprises an outer wing, an inner wing, an outer wing sliding groove, an inner wing sliding groove, a lead screw module and a push rod mechanism. The inner wing is fixed in the outer wing, and when the lead screw module reciprocates at a constant speed, the inner wing and the outer wing are matched with each other through the sliding groove and the cylindrical pin to realize action; the push rod mechanism is composed of two sections of long rods which are arranged in parallel, one end of each long rod is fixed to a sliding table of the lead screw module, the other end of each long rod is matched with sliding grooves of the outer wing and the inner wing, the outer wing is designed to be spliced with two sections of linear sliding grooves with special angles, and the inner wing is designed to be spliced with linear sliding grooves and special curve sliding grooves. And the push rods with corresponding angles are driven to move along the sliding chutes of the outer wing and the inner wing, so that the outer wing and the inner wing rotate and extend out along the sliding rails at constant speed. The constant-speed telescopic mechanism converts constant-speed linear motion into constant-speed rotary motion through mutual cooperation of specially designed sliding grooves, the structural design is simple, and functions are achieved quickly, efficiently and accurately.

    本发明公开了一种应用于变后掠飞行器的匀速伸缩结构,包括外翼、内翼、外翼滑槽、内翼滑槽、丝杆模组和推杆机构。内翼固定在外翼的内部,当丝杠模组匀速往复运动时,内翼和外翼通过滑槽和圆柱销相互配合实现动作;推杆机构为两段长杆平行配置,一端与丝杠模组的滑台固定,另一端与外翼和内翼的滑槽配合,外翼设计带有特殊角度两段直线滑槽拼接,内翼设计为直线与特殊曲线滑槽拼接,丝杆模组匀速运动时,带动对应角度的推杆沿着外翼和内翼滑槽运动,实现外翼和内翼沿着滑轨匀速旋转伸出。匀速伸缩机构通过特殊设计滑槽相互配合将匀速直线运动转变为匀速旋转运动,结构设计简单,功能实现快速高效准确。
