[0029] The inside of the pedal 201 is provided with a storage battery, and the storage battery is electrically connected with the controller 203, the top of the controller 203 is provided with a press trigger switch, and the bottom is provided with a signal transmitter, and the storage battery in the pedal 201 is powered to the signal transmitter through the press trigger switch.

[0030] The bottom of the pedal 201 is provided with a hollow spherical chute, the position of the controller 203 on the pedal 201 corresponds to the bottom of the arch of the human body, and the controller 203 is embedded in the pedal 201, and the plane on the top of the pedal 201 is kept at a distance of 2cm.

[0031] The rotating shaft 211 is movably installed in the inside of the main rod 209, the rotating shaft 211 is the same length as the damping strip 212, the contact surface between the damping strip 212 and the rotating shaft 211 is a relatively smooth and hard metal block, and the contact surface between the damping strip 212 and the main rod 209 is a damping piece with elasticity and large friction coefficient.

[0032] The annular bushing 214 is fixedly sleeved in the inside of the positioning groove 303, and the damping strip 212 is movably installed in the inside of the limiting groove 210.

[0033] It should be further explained that: when the patient needs rehabilitation training, first, the device is placed on one side of the seat, then sit on the seat, and then place both feet on the top of the pedal 201, and fix both feet on the top of the pedal 201 through the magic tape 204, the clasp 205 and the heel stopper 202, at this time, both feet can drive the pedal 201 to move in the horizontal direction at will, the pedal 201 rotates around the spherical sliding sleeve 213, thereby driving the counterweight 216 to move in the opposite direction, in this process, the patient can effectively train the gastrocnemius muscle, the soleus muscle, the quadriceps muscle and the gluteus maximus muscle by making the force against the counterweight 216.

[0034] As Figure 6As shown, the driving mechanism 3 comprises slide rails 301, a slide plate 302, positioning grooves 303, a threaded groove 304, a bearing plate 305, a lead screw 306 and a second servo motor 307. The slide rails 301 are symmetrically arranged about the housing 1. The slide plate 302 is movably mounted on one side of the slide rails 301. The positioning grooves 303 are formed on the left and right sides of the top of the slide plate 302. The threaded groove 304 is formed at the center point of the top of the slide plate 302. The lead screw 306 is threadedly connected in the threaded groove 304. The bearing plate 305 is movably mounted on the top of the lead screw 306. The lead screw 306 is fixedly connected to the output end of the second servo motor 307. The second servo motor 307 is fixedly connected to the bottom of the housing 1. The bearing plate 305 is fixedly connected to the top of the housing 1.

[0035] It should be further explained that when it is necessary to adjust the distance between the spherical sliding sleeve 213 and the weight block 216, thereby increasing or decreasing the force required by the user for training, the second servo motor 307 is started to drive the lead screw 306 to rotate, thereby driving the slide plate 302 to move up and down along the direction of the lead screw 306, further driving the spherical sliding sleeve 213 and the annular bushing 214 to move simultaneously. When the spherical sliding sleeve 213 is close to the weight block 216, the patient is relatively labor-saving. When the spherical sliding sleeve 213 is away from the weight block 216, the patient is relatively labor-consuming.

[0036] The working principle of the above embodiment is that first, the resistance of the equipment is adjusted according to the rehabilitation condition of the patient. The distance between the spherical sliding sleeve 213 and the weight block 216 is adjusted, thereby increasing or decreasing the force required by the user for training. The second servo motor 307 is started to drive the lead screw 306 to rotate, thereby driving the slide plate 302 to move up and down along the direction of the lead screw 306, further driving the spherical sliding sleeve 213 and the annular bushing 214 to move simultaneously. When the spherical sliding sleeve 213 is close to the weight block 216, the patient is relatively labor-saving. When the spherical sliding sleeve 213 is away from the weight block 216, the patient is relatively labor-consuming.

[0037] Next, when the patient needs to perform rehabilitation training, first, the device is placed on one side of the seat, then the patient sits on the seat, and then the patient places his feet on the top of the pedal 201, and fixes the feet on the top of the pedal 201 by the magic tape 204, the clasp ring 205 and the heel stop plate 202. At this time, the feet can drive the pedal 201 to move in the horizontal direction at will. The pedal 201 rotates about the spherical sliding sleeve 213, thereby driving the weight block 216 to move in the opposite direction.

[0038] Finally, by manually pressing the controller 203, the built-in power supply of the control pedal 201 supplies power to the signal transmitter at the bottom of the controller 203, when the controller 203 is powered on, the signal transmitter controls the first servo motor 207 to start, thereby driving the rotating shaft 211 to rotate inside the main rod 209, until the rotating shaft 211 extrudes the damping strip 212 to the spherical sliding sleeve 213, after increasing the friction between the damping strip 212 and the spherical sliding sleeve 213, the spherical sliding sleeve 213 is fixed on one side of the main rod 209.

[0039] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not intended to limit the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
