The invention relates to the field of medical facility automation, in particular to a lower limb rehabilitation training robot. The lower limb rehabilitation training robot comprises a lower limb rehabilitation training mechanism and a walking trolley mechanism. The lower limb rehabilitation training mechanism comprises a waist fixing base, hip joint motors, thigh connecting rods, thigh fixing belts, knee joint motors, crus connecting rods, crus fixing belts, ankle joint motors and sole supporting bases. The waist fixing base and the thigh connecting rods, the thigh connecting rods and the crus connecting rods, and the crus connecting rods and the sole supporting bases are connected respectively through rotating pairs, and rotate relatively by a certain angle under driving of the related motors to form coordinating gait movement. The walking trolley mechanism comprises a trolley frame, wheels, a handle and a hanging belt. The lower limb rehabilitation training mechanism is used for rehabilitation training of the aspects such as muscular strength, mobility of joint and coordination after lower limb contracture of limb hemiplegic patients, the control principle is simple, wearing and operation are easy, the application range is wide, and patients can select different modes for training according to different rehabilitation stages.
