The invention provides a variable-diameter wheel type structure which comprises a plurality of connecting rod structures and a plurality of circumferentially-deformed flexible honeycomb structures, a connecting rod support I and a connecting rod support II are arranged on a supporting shaft, the connecting rod support I is in sliding connection with the supporting shaft, the connecting rod support II is fixedly connected with the supporting shaft, the circumferentially-deformed flexible honeycomb structures are fan-shaped, and the connecting rod supports I and II are fixedly connected with the supporting shaft. The multiple circumferentially-deformed flexible honeycomb structures are distributed in the circumferential direction of the supporting shaft, a connecting rod structure is arranged between every two adjacent circumferentially-deformed flexible honeycomb structures, and each connecting rod structure comprises a rod piece I, a rod piece II, a rod piece III, a rod piece IV, a rod piece V, a rod piece VI, a rod piece VII and a rod piece VIII. The rod piece VII and the rod piece VIII are hinged to the opposite sides of the two adjacent circumferential deformation flexible honeycomb structures. The multiple connecting rod mechanisms drive the multiple circumferentially-deformed flexible honeycomb structures to synchronously stretch or contract, and reducing of the wheel type structure is achieved. While the diameter of the wheel type structure is changed, the circumferential shape of the wheel type structure in different diameter states can be kept.
本发明提出了一种可变直径轮式结构,包括多个连杆结构以及多个周向变形柔性蜂窝状结构,支撑轴上设有连杆支座I和连杆支座II,连杆支座I与支撑轴滑动连接,连杆支座II与支撑轴固定连接,周向变形柔性蜂窝状结构呈扇形,多个周向变形柔性蜂窝状结构沿支撑轴周向分布,每两个相邻周向变形柔性蜂窝状结构之间设有一个连杆结构,连杆结构包括杆件Ⅰ、杆件Ⅱ、杆件Ⅲ、杆件Ⅳ、杆件V、杆件VI、杆件VII以及杆件VIII,杆件VII和杆件VIII铰接在相邻两个周向变形柔性蜂窝状结构相对的一侧。多个连杆机构带动多个周向变形柔性蜂窝状结构同步伸展或收缩,实现轮式结构的变径。本发明可以在改变轮式结构直径的同时,保持不同直径状态下轮式结构的圆周形状。
