a linkage unit arranged on a frame; and

a function module, comprising:
a sensing unit that collects body function data, wherein the body function data comprises pedal pressure, exercise duration, and exercise mileage;
a mobile terminal; and
a data-processing cloud terminal comprising a data-processing unit and a rehabilitation database,
wherein the sensing unit comprises a single-chip microcomputer, a pressure sensor that collects the pedal pressure data, a time sensor that collects the exercise duration data, a velocity sensor that collects the exercise mileage data, an amplification circuit and an A/D conversion circuit that amplifies and transmits body function data collected by the pressure, time and velocity sensors to the single-chip microcomputer, wherein the single-chip microcomputer sends the body function data to the mobile terminal,
wherein the mobile terminal collects physiological data of 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, and

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 comprise rehabilitation training programs associated with physiological data and/or body function data of training objects, and
wherein the data-processing cloud terminal performs 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 a pedal,
wherein the mechanical structure module at least comprises: a groove plate for supporting a cam roller, the 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 or driving a guide shaft to rotate, a linear bearing for supporting the guide shaft, the guide shaft for driving a slider to rotate, the slider for driving the link to operate, an axis pin for connecting the link and the slider, and the cam roller for making the slider move along a groove trajectory of the groove plate; wherein the pedal and the link are rigidly connected, while the link is hinged to the first rocker and the axis pin respectively, the rocker is hinged to the frame, the connecting bulge is provided with two parallel columnar through holes, the linear bearing is received in the columnar through hole, the guide shaft passes through the linear bearing, the guide shaft and the slider are rigidly connected to each other, and the cam roller is rigidly connected to the connecting bulge through the axis pin, and the cam roller performs curved movement along the groove plate, as the curvature radius changes, the guide shaft performs linear movement with respect to the connecting bulge, the linear bearing is arranged in the connecting bulge for reducing mechanical wear between the guide shaft and the connecting bulge, thereby improving the service life.

2. The rehabilitation training system of claim 1 , 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.

3. The rehabilitation training system of claim 1 , 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.

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

5. The rehabilitation training system of claim 1 , wherein the data-processing cloud terminal includes a data-processing unit and the rehabilitation database, wherein the data-processing unit serves to perform correlation matching on collected data, and the rehabilitation database serves to store the collected data comprising the first related 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.
