The bicycle labor-saving pedal mechanism convenient to ride comprises a fixed sleeve, disc bodies are fixedly connected to the two ends of the fixed sleeve respectively, and a movable ring is rotationally connected to the outer ring of each disc body; a transmission shaft rotatably penetrates through the two groups of disc bodies and is eccentrically arranged on the two groups of disc bodies, two ends of the transmission shaft are respectively connected with a fixed arm, the two groups of fixed arms extend reversely, the outer wall of each group of movable ring is connected with a movable arm through a connecting rod, the movable arms correspond to the fixed arms one by one, and the movable arms are in sliding connection with the fixed arms; pedals are mounted at the ends, away from the movable ring, of the movable arms. According to the bicycle, the length of the power arm is effectively increased, so that the power can be transmitted to the wheels more easily by stepping on the pedal plate, the labor-saving effect is achieved, the foot can smoothly step on the pedal plate, the situation that the foot is separated from the pedal plate due to the fact that the power arm is too long is avoided, riding is convenient, and safety is good.
本发明公开了一种便于骑行的自行车省力脚踏机构,包括固定套筒,固定套筒两端分别固接有盘体,每组盘体外圈均转动连接有活动圈;两组盘体上转动穿设有传动轴,传动轴在两组盘体上偏心设置,传动轴的两端分别连接有固定臂,两组固定臂反向延伸,每组活动圈外壁通过连接杆连接有活动臂,活动臂与固定臂一一相对应,且活动臂与固定臂滑动连接,且活动臂远离活动圈的一端安装有脚踏板;本发明效增长了动力臂的长度,使得脚踩脚踏板更易将动力传递给车轮,起到省力的效果,且使得脚可顺利踩在脚踏板上,不会由于动力臂过长导致脚从脚踏板上脱离,骑行方便,安全性好。
