The invention aims to provide an ankle flexion and extension rehabilitation training device. The training device comprises a frame, rigid-flexible mixing linkage support chains, rope traction support chains and a pedal. A first torque motor and a sliding rail are fixed to a stand column of the frame, a first winch is installed on the first torque motor, direct-current motors are connected with lead screws in a driving mode, nuts are matched with the sliding rails and driven by the direct-current motors to move along sliding rails, passing wheels are installed on the nuts, one end of a first rope is wound on the first winch, and the other end of the first rope is connected with the first side face of the pedal through the corresponding passing wheel. A second torque motor is fixed to a stand column of the frame, a second winch is installed on the second torque motor, one end of a second rope is wound on the second winch, the other end of the second rope is connected with the second side face of the pedal, and the first side face and the second side face are opposite. Driving unit arrangement is facilitated, besides, system dynamic performance and system flexibility are enhanced, and the requirements of rehabilitation training can be met better.
Description
technical field [0001] The invention relates to a rehabilitation mechanism, specifically a lower limb rehabilitation mechanism. Background technique [0002] Medical theory and practice have proved that patients with cerebral palsy sequelae or limb injuries caused by accidents need limb training in order to restore limb function and prevent muscle "disuse" atrophy and joint stiffness. In order to overcome the shortage of professional medical personnel and improve the effect of rehabilitation training, various rehabilitation training devices have emerged. Generally, active rehabilitation training devices are attached to the limbs of the trainee, and the limbs are driven by the expected movement trajectory to achieve the effect of rehabilitation training. . Elderly people have weak athletic ability, and through robot-assisted exercise training, they can improve their motor function. [0003] At present, the relevant literature at home and abroad mainly includes the following...
