The invention relates to a single-degree-of-freedom deployable deformation wheel structure which is formed by connecting N identical plane symmetric structure units end to end, and N is larger than or equal to 3. Each plane symmetrical structure unit is a single closed-loop mechanism formed by rotationally connecting a fan-shaped flat plate A1, a trapezoidal block B1, a trapezoidal block C1, a fan-shaped flat plate A2, a trapezoidal block B2 and a trapezoidal block C2 end to end, the fan-shaped flat plate A1 and the fan-shaped flat plate A2 are the same in structure, the trapezoidal block B1 and the trapezoidal block B2 are the same in structure, and the trapezoidal block C1 and the trapezoidal block C2 are the same in structure. The sum of the central angles of the fan-shaped flat plates A1 or the fan-shaped flat plates A2 of the N surface symmetrical structure units is 360 degrees; and the outer side edges of the trapezoidal block B1 and the trapezoidal block C1 of any plane symmetrical structure unit are rotationally connected with the outer side edges of the trapezoidal block C2'and the trapezoidal block B2 'of the adjacent plane symmetrical structure unit respectively, so that the N plane symmetrical structure units are connected end to end to form the expandable deformation wheel structure. The deployable deformation wheel structure has a single degree of freedom, is easy to control, variable in diameter, large in folding and unfolding ratio and high in adaptability to a complex road surface environment.

    本发明涉及一种单自由度的可展变形轮结构,由N个相同的面对称结构单元首尾连接而成,N≥3;每个面对称结构单元由扇形平板A1、梯形块B1、梯形块C1、扇形平板A2、梯形块B2、梯形块C2首尾转动连接成单闭环机构,其中扇形平板A1和扇形平板A2结构相同,梯形块B1和梯形块B2结构相同,梯形块C1和梯形块C2结构相同,且N个面对称结构单元的扇形平板A1或扇形平板A2的圆心角之和为360度;任一面对称结构单元的梯形块B1、梯形块C1的外侧边分别与其相邻面对称结构单元的梯形块C2'、梯形块B2'的外侧边转动连接,从而使N个面对称结构单元首尾连接形成可展变形轮结构。该可展变形轮结构具有单自由度,易于操控,且可变直径,折展比大,对复杂路面环境的适应性强。
