The invention relates to the field of walking mechanisms, in particular to a wheel type walker formed by matching a plurality of pairs of hinge mechanisms, during moving, three soles touch the ground at the same time instead of tangential rolling of rims of common rubber wheels, and rolling advancing of the wheels is changed into alternate walking advancing of the soles. According to the main cooperation, three pairs of splayed hinge mechanisms on the front face and three pairs of splayed hinge mechanisms on the back face are arranged, each pair of splayed hinge mechanisms is connected through a sole upper connecting component to form a hexagonal annular mechanism, and the hexagonal annular mechanism is arranged on a supporting circular hub. The whole motion structure adopts a phase cross arrangement mode. During movement, the connecting rods drive the soles to move, and the central point of the mechanism, namely the center of the disc, does not vibrate up and down and is horizontal, which is the same as the movement condition of the wheels. Meanwhile, the contact area between the sole and the ground is larger than that of the tire, so that larger friction force can be provided. The wheel type walker is suitable for non-road occasions where wheels cannot move or are not suitable for movement, and can normally work in landforms such as snowfields, deserts and grasslands.
本发明涉及行走机构领域,发明了一种由多对铰链机构配合而成的轮式步行器,移动时三个脚掌同时着地代替了一般橡胶车轮的轮缘的切线滚动,变轮子的滚动前进为脚掌的交替步行前行。主要配合是,正面三对八字形铰链机构,背面三对八字形铰链机构,每对八字形铰链机构又由脚掌上连接构件相联,构成一个六边形环状机构,置于支撑圆形轮毂上。整个运动结构采用相位交叉排布的方式。移动时由连杆带动脚掌运动,而机构中心点即圆盘中心不上下振动,水平不变,和轮子运动时的情况相同。同时脚掌与地面的接触面积比轮胎大,能提供更大的摩檫力。轮式步行器适用于轮子无法或不适于运动的非路面场合,在雪地、沙漠、草原等地形都可以正常工作。
