In the passive training process of the patient, the power device drives the driving device to act, and then the action is transmitted to the foot of the patient through the left pedal 3 and the right pedal 4, and the specific working process is as follows: in the passive training process, the electromagnetic clutch 13 controls the rotating shaft of the motor 12 to be connected with the shaft of the driving sprocket 14, the motor 12 rotates to drive the driving sprocket 14 to rotate, meanwhile, the magnetic control wheel 15 regulates and controls the rotating speed of the driving sprocket 14, the driving sprocket 14 transmits power to the left driving unit and the right driving unit through the rotating shaft transmission between the chain and the wheel pair 18, the wheel pair 18 rotates to enable the eccentric shafts to rotate, two groups of wheel pairs 18 in the left driving unit synchronously rotate, the eccentric shafts on the two groups of wheel pairs 18 synchronously rotate in the same phase, and as the two ends of the left pedal 3 are hinged with the eccentric shafts through the sleeve 19, the eccentric shafts drive the left pedal 3 to do periodic rotation while the wheel pair 18 rotates, and the right driving unit and the left driving unit have the same motion process, and the difference is only that the phase of the eccentric shafts in the right driving unit relative to the central shaft of the wheel pair 18 is different from the phase of the eccentric shafts in the left driving unit, and the left driving unit has staggered motion track to simulate the left leg and right leg alternating motion when a human walk.
The left pedal 3 and the right pedal 4 are connected with the pedal groove 11 through a gait device, the gait device realizes the sliding of the pedal groove 11 to a certain extent by the sliding of the sliding block 24 on the sliding rail 23 during working, the sliding resistance of the sliding block 24 and the sliding rail 23 is realized through the damping adjusting device 27, the linear sliding of the gait device is combined with the periodical rotation of the left pedal 3 and the right pedal 4, so that the gait of a patient during training is closer to the gait simulation under the real condition, and the rehabilitation training of the patient is facilitated.
In the active training process of a patient, the autonomous movement of the patient drives the driving device to act, the driving device drives the left pedal 3 and the right pedal 4 to rotate, the gait device realizes the sliding action of the pedal groove 11 and the left pedal 3 and the right pedal 4, and the simulation of the gait track of the patient is realized jointly, so that the patient carries out rehabilitation training according to the established gait track, and the transmission principle among the driving device, the left pedal 3, the right pedal 4 and the gait device is the same as that during passive training, and is not repeated here.
The above-described embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention, so that all equivalent changes or modifications of the structure, characteristics and principles described in the claims should be included in the scope of the present invention.
