The invention relates to active-passive lower limb rehabilitation equipment and achieves rehabilitation training for the problems that the flexibility of lower limbs is constantly decreased and even the lower limbs are paralyzed due to recession of physiological functions of elders. According to the constitution of the active-passive lower limb rehabilitation equipment, an outer sleeve in a supporting mechanism is connected with an outer shell I in a protective mechanism, the outer sleeve in the supporting mechanism is connected with an outer shell II in the protective mechanism, bottom squaresteel in the supporting mechanism 1 is connected with the outer shell I in the protective mechanism, the bottom square steel in the supporting mechanism is connected with the outer shell II in the protective mechanism, and a motor supporting plate in a movement mechanism is connected with the bottom square steel in the supporting mechanism and a bearing supporting frame in the movement mechanism;retractable adjustment is achieved through cooperation between the outer sleeve and an inner pipe, and a protective function is achieved on the movement mechanism through the protective mechanism. The equipment has the advantages that the structure is simple and novel, the equipment is convenient to use, the treatment effect is effectively improved by adopting a motor for driving the lower limbsof patients for passive training, and correspondingly necrotic nerves are recovered through rehabilitation exercises; therefore, the rehabilitation training for the patients is scientific and effective, and the equipment is applicable to a wide range of people.
