The invention provides a mechanical arm and a charging device. The mechanical arm comprises a plurality of universal joint sets connected in sequence, and each universal joint set comprises a universal joint fork and a cross shaft. The mechanical arm is provided with three pull wire sets along the circumference, leads of each pull wire set comprise a first lead, a second lead and a third lead, flange plates are arranged on the outer walls of the circumferences of the universal joint forks, the three first leads sequentially and vertically penetrate through the flange plates of the a universal joint forks from the starting end of the mechanical arm, and the three second leads sequentially and vertically penetrate through the flange plates of the a universal joint forks from the starting end of the mechanical arm. The three second leads sequentially and vertically penetrate through the flange plates of the (a + b) universal joint forks from the starting end of the mechanical arm, the three third leads sequentially and vertically penetrate through the flange plates of the (a + b + c) universal joint forks from the starting end of the mechanical arm, and a, b and c are all integers. The charging device comprises a rack and the mechanical arm. The mechanical arm is of a multi-section structure, the degree of freedom is higher, the charging gun can have a wider coverage range, and the mechanical arm is formed by multiple sections of universal joint sets and is convenient to bend and store.

    本申请提供一种机械臂及充电装置,机械臂包括:多个依次相连的万向节组,万向节组包括万向节叉及十字轴。机械臂沿圆周设有三处牵引线组,且每处牵引线组的引线均包括第一引线、第二引线及第三引线,万向节叉的圆周外壁设有凸缘板,三根第一引线从机械臂的起始端依次且垂直穿过a个万向节叉的凸缘板,三根第二引线从机械臂的起始端依次且垂直穿过a+b个万向节叉的凸缘板,三根第三引线从机械臂的起始端依次且垂直穿过a+b+c个万向节叉的凸缘板,a、b、c均为整数。充电装置,包括:机架及上述的机械臂。机械臂为多段结构,自由度更高,可使充电枪具有更广的覆盖范围,而且机械臂采用多段万向节组构造而成,便于弯曲收纳。
