When the rehabilitation device is used, a patient firstly lies on the box body 1, the rope at the upper end of the top plate 9 is fixed at the waist, and if the patient just enters a rehabilitation treatment stage, the assistance movement is suitable. When the device is used for assisting in movement, the force provided by muscles of a patient is not enough to overcome the gravity of the patient, at the moment, a force needs to be provided by the device, so that the two resultant forces can overcome the gravity of the waist of the patient, specifically, the motor 18 is started, the motor 18 drives the second friction wheel 5 to rotate through the first friction wheel 4, the second friction wheel 5 drives the worm 3 to rotate through the spline shaft 19, the worm 3 rotates to drive the worm wheel 7 to rotate, the worm wheel 7 rotates to drive the cylinder 6 to rotate, the cylinder 6 rotates to drive the lead screw 8 to move upwards through the threads, the lead screw 8 drives the top plate 9 to move upwards to provide upward supporting force for the waist of the patient, when the top plate 9 rises to a certain height, the distance detector sends a signal to control the motor 18 to rotate reversely, the motor 18 rotates reversely to enable the worm wheel 7 to rotate reversely, the worm wheel 7 drives the lead, the distance detector sends a signal to control the motor 18 to rotate forwards and enter the next cycle.

In the above process, in the rising stage of the top plate 9, if the patient does not exert force or exerts insufficient force, the first friction wheel 4 and the second friction wheel 5 slip to prevent strain.

In the assisted exercise training, if the load of the muscle of the user needs to be increased or reduced, the push rod 20 only needs to be screwed at the moment, the pressure between the first friction wheel 4 and the second friction wheel 5 can be adjusted by the left-right movement of the push rod 20, and therefore the maximum supporting force which can be provided for the waist of the patient by the device can be adjusted.

Along with the time lapse, the muscular function of disease resumes gradually, the speed of the upper part of the body that can inevitably appear the waist when the waist rises is greater than the speed of lead screw 8 axial motion, lead screw 8 drives whole casing 2 through drum 6 and moves upwards, pin 16 inclined plane is down this moment, fly leaf 15 can only the rebound, the speed that the waist rises equals casing 2 speed and the sum of lead screw 8 for drum 6 rebound speed, at this in-process, fly leaf 15 can only rebound under the effect of pin 16, if the waist is uncomfortable this moment, fly leaf 15 can provide stable support to the waist under the effect of pin 16, make the waist in time stabilize, prevent to fall and cause the secondary injury. When the top plate 9 reaches the upper limit position, when the pull force of the vertical rod 13 on the rack 12 through the spring is large enough, the rack 12 pulls the rectangular block 11 upwards to force the limiting pin 22 to contract towards the pin 16 hole, then the limiting pin 22 is clamped in the groove 23 on the lower side, the rack 12 moves upwards to drive the gear 14 to rotate, the gear 14 rotates to drive the pin 16 to rotate 180 degrees through the central shaft on the gear 14, the movable plate 15 can only move downwards, meanwhile, the distance sensor sends a signal to enable the motor 18 to rotate reversely, the shell 2 and the top plate 9 both fall down, when the rack 12 receives enough downward pressure of the pressure spring, the rack 12 drives the rectangular block 11 to break through the limiting pin 22 and move downwards, the gear 14 drives the pin 16 to restore to the initial state, and the limiting pin 22 is clamped in the groove 23 on.

In the whole process of rehabilitation training, because the muscles are in unhealthy states, the force provided by the muscles is not constant, so that the instantaneous speed is always changed when the waist is lifted, and no matter how the instantaneous speed is changed, the top plate 9 in the device can be attached to the waist, so that constant supporting force can be provided for the waist, in addition, the waist can be prevented from moving downwards, and the probability of injury to the muscles of patients is reduced.

When the patient enters the later stage of the rehabilitation training, the resistance training is needed to be carried out at the moment, the waist muscle is strengthened and trained, the waist of the patient is tied up by the rope on the top plate 9 at the moment, the waist of the patient upwards drives the top plate 9 to upwards through the rope, the top plate 9 upwards moves by pulling the whole shell 2 through the screw 8, and at the moment, the waist bears the gravity of the whole shell 2 and some parts thereon.

The invention has the outstanding advantages and remarkable progress that:

1. in the device, the top plate 9 can be well attached to the waist, even if the speed of the waist at a certain stage in the rising process exceeds the rising speed of the screw 8, the movable plate 15 in the device provides enough supporting force for the waist under the action of the pin 16, and the screw 8 can provide equal and constant supporting force for the waist at any time.

2. Under the helping hand motion state, the waist is at the uniform velocity upwards, and ascending speed just equals with the speed that lead screw 8 rises, but if a certain sensation is uncomfortable in the twinkling of an eye, can utilize the auto-lock of fly leaf 15, pin 16 and lead screw 8 to guarantee that the waist is fixed at once in the device, prevents to fall, also avoids the secondary damage.

3. Pressure between two friction pulley in this device is adjustable, also can adjust the limit to the waist provide the holding power, and when the waist descends, the transmission efficiency of lead screw 8 itself is lower, and lead screw 8 descending speed is slower, can not cause secondary damage.

4. The worm and gear 3 in the device can effectively increase torque, has lower rotating speed, further reduces the rotating speed through thread transmission, can provide stable supporting force for the waist, reduces fluctuation and is beneficial to muscle rehabilitation.
