Abstract

A rehabilitation training system for lower limb rehabilitation comprises a function module comprising: a sensing unit that collects body function data comprising pedal pressure, exercise duration, and exercise mileage; and a mechanical structure module comprising: a driving unit and a linkage unit arranged on a frame; a groove plate for supporting a cam roller, a pedal for supporting the weight of the training object and driving the lower limb of the training object to move; a link for transmitting kinetic energy to the pedal; a rocker for supporting the link; a connecting bulge driving a guide shaft to rotate; a linear bearing supporting the guide shaft and an axis pin for connecting the link and the slider.

First claim

What is claimed is:

1. A rehabilitation training system for lower limb rehabilitation training by a training object, the system comprising:
a function module comprising:
a sensing unit that collects body function data comprising pedal pressure, exercise duration, and exercise mileage; and

a mechanical structure module comprising:
a driving unit and a linkage unit arranged on a frame;
a groove plate for supporting a cam roller,
a pedal for supporting the weight of the training object and driving the lower limb of the training object to move;
a link for transmitting kinetic energy to the pedal, which is rigidly connected to the link;
a rocker for supporting the link, wherein the rocker is hinged to the frame;
a connecting bulge driving a guide shaft to rotate, wherein the guide shaft is rigidly connected to a slider and drives the slider to rotate such that the slider drives the operation of the link, and wherein the connecting bulge is provided with two parallel columnar through holes;
a linear bearing supporting the guide shaft, wherein the linear bearing is received in a columnar through hole, wherein the guide shaft passes through the linear bearing, and wherein the linear bearing is arranged in the connecting bulge; and,
an axis pin for connecting the link and the slider, wherein the link is hinged to the rocker and the axis pin, wherein the cam roller is rigidly connected to the connecting bulge through the axis pin, wherein the cam roller enables the slider to move along a groove trajectory of the groove plate,
wherein the cam roller performs curved movement along the groove plate such that when the curvature radius changes, the guide shaft performs linear movement with respect to the connecting bulge.

2. The rehabilitation training system of claim 1 , wherein the body function data comprise the support provided by the pedal, the exercise duration, and the exercise mileage data for every exercise training course the training object has taken.

3. The rehabilitation training system of claim 1 , wherein the linkage unit has a link mechanism and a slide mechanism linked thereto such that the slide mechanism can be moved together with the link mechanism so that the slide mechanism is driven by the driving unit to slide along a groove plate, and
wherein the link mechanism is linked to move together with the slide mechanism such that the link mechanism moves to a corresponding position so that the slide mechanism can assist the training object in performing lower limb rehabilitation training.

4. The rehabilitation training system of claim 1 , wherein the sensing unit comprises:
a pressure sensor, a time sensor, a velocity sensor, an amplification circuit, an A/D conversion circuit, and a single-chip microcomputer,
wherein signal data collected by the pressure sensor, the time sensor and the velocity sensor is amplified by the amplification circuit and transmitted to the single-chip microcomputer through the A/D conversion circuit, and
wherein the single-chip microcomputer performs preliminary processing on the data.

5. The rehabilitation training system of claim 1 , wherein the function module further comprises:
a mobile terminal; and
a data-processing cloud terminal comprising a data-processing unit and a rehabilitation database,
wherein the mobile terminal collects physiological data from the training object and sends both the body function data and the physiological data to the data-processing cloud terminal, wherein the physiological data include body height, body weight, and age of the training object.

6. The rehabilitation training system of claim 5 , wherein the data-processing cloud terminal performs:
a first matching between data collected by the sensing unit, and expert data stored in the data-processing cloud terminal to provide a first rehabilitation training program, and stores the first rehabilitation training program in the data-processing cloud terminal, wherein the expert data comprises rehabilitation training programs associated with physiological data and/or body function data of training objects, and
a second matching between physiological data of the training object collected by the mobile terminal and the first rehabilitation training program to generate a second rehabilitation training program, stores the second rehabilitation training program in the data-processing cloud terminal, and sends the second rehabilitation training program to the mobile terminal as a recommended rehabilitation training scheme, wherein the second rehabilitation training program comprises a duration of each training session and/or a number of training sessions per day and/or a training cycle and/or an exercise mileage and/or support provided by the pedal.

7. The rehabilitation training system of claim 6 , wherein the first matching is a correlation matching between the expert data stored in the data-processing cloud terminal and the pressure data collected by the sensing unit.

8. The rehabilitation training system of claim 5 , wherein the data-processing unit performs correlation matching on collected data, and the rehabilitation database serves to store the collected data comprising the expert data, the data collected by the sensing unit, the data collected by the mobile terminal, and the data of matching results generated during the first data matching.

9. The rehabilitation training system of claim 5 , wherein the mobile terminal controls a motor in the mechanical structure module of the rehabilitation training system according to the recommended rehabilitation training scheme the mobile terminal receives and affects the exercise mileage of the training object by adjusting the speed of the motor; and
wherein the mobile terminal displays recommendations about the duration of each training session, the number of training sessions per day, the training cycle, the exercise mileage and the support provided by the pedal in the recommended rehabilitation training scheme to the training object by means of voice or a list.

10. The rehabilitation training system of claim 5 , wherein the mobile terminal sends pressure data, time data, and travel data collected by the sensing unit to the data-processing cloud terminal for data update and displays variations of the pressure data, time data, and travel data to the training object by means of a list or a diagram.

11. The rehabilitation training system of claim 1 , wherein the rehabilitation training system further comprises a rehabilitation evaluating unit which evaluates a physical status and rehabilitation status of the training object according to physiological information and exercise information of the same collected by the sensing unit and adjusts an exercise frequency and exercise duration of the training object according to the physical status in a real-time manner.

12. The rehabilitation training system of claim 11 , wherein the rehabilitation evaluating unit adjusts the exercise frequency of the pedal based on the physiological information of the training object by adjusting a driving frequency of the driving unit.

13. The rehabilitation training system of claim 11 , wherein when the physiological information data of the training object shows an abnormality, the rehabilitation evaluating unit stops guiding the training object to perform lower limb rehabilitation training, and returns the training object to a standard sitting posture.

14. The rehabilitation training system of claim 11 , wherein the rehabilitation evaluating unit comprises an alarm unit that gives out an alarm when the physiological information data of the training object show an abnormality.
