The invention belongs to the technical field of robots, and particularly relates to a robot lower limb capable of being replaced quickly. The robot lower limb comprises a thigh joint, a first hydraulic rod, a mounting shell, a thigh, a knee joint, a shank, an ankle joint and a foot. During jumping, the impact force borne by a limb body is increased, at the moment, the impact force borne by the limb body extrudes corresponding second hydraulic rods through transmission of mounting columns, connecting rods, friction arc plates and guide arc plates, the hydraulic rods have certain telescopic resistance, so that swing of the mounting columns and the connecting rods on the lower side is blocked, under the condition, the impact force of the bottom surface to the limb body is transmitted upwards, a second buffer spring in a second buffer mechanism is compressed, a friction cambered surface is in contact friction with the upper side face of a second sliding groove in a second cambered surface guide rail, and through friction braking, the situation that the limb body continues to swing rapidly under the impact force, the telescopic resistance of the second hydraulic rods is too large, and internal breakage is caused is prevented.
本发明属于机器人技术领域,尤其涉及一种机器人可快速更换的下肢,它包括大腿关节、第一液压杆、安装壳、大腿、膝关节、小腿、踝关节、足,本发明中在跳跃的时候,肢体受到的冲击就会变大,此时肢体受到的冲击力就会通过安装柱、连接杆、摩擦弧板和导向弧板的传动挤压对应的第二液压杆,因液压杆具有一定的伸缩阻力,所以,此时下侧安装柱和连接杆的摆动就会受阻,这种情况下,底面对肢体的冲击力就会向上传递,使得第二缓冲机构中的第二缓冲弹簧压缩,摩擦弧面和第二弧面导轨中第二滑槽的上侧面接触摩擦,通过摩擦制动,防止在冲击力肢体继续快速摆动,导致第二液压杆伸缩阻力过大,导致内部憋坏。
