[0017] Referring to Figures 1-4 , the embodiment is a kind of ankle rehabilitation auxiliary training device, including fixed support 1, the top of fixed support 1 is equipped with a pedal 3, the rear end bottom of pedal 3 is equipped with a pivot 8, the both ends of pivot 8 are rotatably connected between fixed support 1, the lower end of fixed support 1 corresponds to the front end of pedal 3 and is equipped with electric lifting mechanism 2, the top of electric lifting mechanism 2 is movably connected with the bottom of pedal 3, electric lifting mechanism 2 is equipped with control panel, control panel is electrically connected with electric lifting mechanism 2, control panel is equipped with button, button is used to control electric lifting mechanism 2 start-stop, rise or fall.

[0018] Further, the electric lifting mechanism 2 is provided with a frequency conversion motor 22, and the control panel is provided with a speed regulating button.

[0019] Further, the electric lifting mechanism 2 includes a scissor jack, a screw rod 21 for driving is arranged in the middle of the scissor jack, one end of the screw rod 21 is connected with a speed reducer, and the input end of the speed reducer is provided with the frequency conversion motor 22.

[0020] Further, it further includes a leg pressing mechanism, the leg pressing mechanism includes a soft pad 7, the four corners of the soft pad 7 are respectively equipped with an adjustable length binding belt 6, and the binding belt 6 is connected with the fixed support 1.

[0021] ​​Further, the top surface of the pedal 3 is provided with a tightening belt A5 at the front end, which is used to lock the foot.

[0022] Further, the side of the top surface of the pedal 3 is also provided with a tightening belt B4.

[0023] Further, the fixing support 1 is provided with an upper limit switch and a lower limit switch, the upper limit switch is used to limit the maximum height of the pedal 3 when it is turned up, and the lower limit switch is used to limit the minimum height of the pedal 3, and the installation positions of the upper limit switch and the lower limit switch are adjustable.

[0024] The working principle of the utility model is as follows: the patient who does rehabilitation training places the leg to be trained on the pedal 3 in a sitting position, so that the thigh and the calf are roughly perpendicular, then places the soft pad 7 on the thigh, adjusts the length of the belt 6 and clamps it to make the soft pad 7 press the thigh downward so that the bottom surface of the foot is attached to the pedal 3; if the rehabilitation movement in the front and back directions is needed, the foot is sleeved in the tightening belt A5, so that the ankle joint and the rotating shaft 8 are in a straight line, then the electric lifting mechanism 2 is started through the button on the control panel, the speed of the pedal 3 turning up is adjusted according to the own condition, the foot is turned by the turning of the pedal 3, and since the foot is completely attached to the pedal 3, the ankle joint can be moved.

[0025] When the rehabilitation movement in the left and right directions is needed, the foot is attached to the pedal 3 in the transverse direction, so that the length direction of the foot is parallel to the axis of the rotating shaft 8, and the rotating shaft 8 is located on the center line of the foot, the front end and the middle part of the instep are locked and fixed by the tightening belt B4, then the leg pressing mechanism is pressed on the thigh, and the pedal 3 is turned up by starting the electric lifting mechanism 2.

[0026] Before the rehabilitation training is carried out, the positions of the upper limit switch and the lower limit switch are adjusted according to the rehabilitation condition of the patient, so that the up and down turning stroke of the pedal 3 is adjusted, the pedal 3 is automatically stopped when reaching the upper limit switch when turning up, then turns down, is automatically stopped when reaching the lower limit switch when turning down, and then turns up, the pedal 3 is automatically repeated in the limited height of the upper and lower limit switches, and the pedal 3 can also be controlled to stop at any position in the stroke.
