The invention relates to a walking type geometric multiplication labor-saving two-dimensional multi-stage double-connecting-rod lever pedaling tricycle that is characterized in that a group of geometric multiplication labor-saving two-dimensional multi-stage double-connecting-rod levers is arranged on each of the left side and the right side of a support, multiple stages can be two, three, four, five or more stages, a supporting rod is connected to the rear part of each group of levers, and a pedaling wheel is arranged at the tail end of each supporting rod. When the left pedal drives the left geometric multiplication labor-saving two-dimensional multi-stage double-connecting-rod lever to move towards the lower rear portion, the left supporting rod drives the left treading wheel to tread the ground towards the lower rear portion so that the bicycle can move forwards. When the right pedal drives the right geometric multiplication labor-saving two-dimensional multi-stage double-connecting-rod lever to move towards the lower rear portion, the right supporting rod drives the right treading wheel to tread the ground towards the lower rear portion so that the bicycle can move forwards. Through the geometric multiplication labor-saving two-dimensional multi-stage double-connecting-rod lever, the labor-saving effect is achieved in the two aspects of pedaling and propelling. The double-connecting-rod longitudinal and transverse two-dimensional arrangement makes full use of space. The tricycle has the advantages of being firm in structure and labor-saving in riding.
一种步行式几何倍增省力二维多级双连杆杠杆蹬地三轮自行车,支架左右两边各一组几何倍增省力二维多级双连杆杠杆,多级可以是2、3、4、5或更多级,每组杠杆后部连接设置撑杆,撑杆末端设置蹬地轮。当左脚踏带动左几何倍增省力二维多级双连杆杠杆向后下方运行时,左撑杆带动左蹬地轮向后下方蹬地使车前行。当右脚踏带动右几何倍增省力二维多级双连杆杠杆向后下方运行时,右撑杆带动右蹬地轮向后下方蹬地使车前行。本发明通过几何倍增省力二维多级双连杆杠杆,采用蹬地推进两个方面达到省力效果。双连杆纵向横向二维设置充分利用空间。本发明的优点:结构结实,骑行省力。
