[0024] In this utility model, such as Figure 1 and Figure 2As shown, the calf support assembly 30 includes a leg strap 300 for supporting the calf and a grooved support housing 301 with openings at both ends. The grooved support housing 301 is placed flat on the second arc-shaped support plate 23. The leg strap 300 is provided along the edge of the opening from the rear end to the middle of the grooved support housing 301. One side of the leg strap 300 is fixed to one edge of the opening of the grooved support housing 301, and the other side of the leg strap 300 is detachably fastened to the other edge of the opening of the grooved support housing 301. The heel of the shoe 310 is connected to the front ends of the grooved support housing 301. The connection is either flexible or rigid. The other end of the motor mounting plate 313 extends to the outer front end of the grooved support housing 301. The output shaft of the second motor 312 passes vertically through the other end of the motor mounting plate 313 and is connected to the outer front wall of the grooved support housing 301. Latex pads are provided on the inner circumferential wall of the grooved support housing 301 to make the calf wrapping more comfortable. The leg wrap 300 used for fixing is made of Velcro at the interface, and its tightness can be freely adjusted according to the user experience of different users, so that there will be no discomfort due to the fixation being too tight or too loose. During training, the grooved support shell 301 is placed on the second arc-shaped support plate 23. The lower leg is placed inside the grooved support shell 301 and fixed to it by the leg strap 300. When the second motor 312 rotates, it drives the grooved support shell 301 to rotate back and forth along the output shaft of the second motor 312. The lower leg presses against the second arc-shaped support plate 23 through the grooved support shell 301, causing the second arc-shaped support plate 23 to swing along the direction of motor rotation via a universal ball. When the second motor 312 drives the grooved support shell 301 to swing up and down along the vertical plane at an angle, it causes the shoe 310 on the sole of the foot to move up and down on the second arc-shaped support plate 23, performing plantar flexion and dorsiflexion movements (longitudinal movement) of the foot. When the first motor 311 is activated, it performs abduction and adduction movements of the ankle joint (lateral movement). By setting the two motors to move along a predetermined trajectory, it further drives the movement of the human ankle. It can realize plantar flexion and dorsiflexion of the ankle joint, as well as eversion and inversion, ensuring that the ankle can be fully exercised during rehabilitation exercises. The training device of this application enables the ankle joint to perform multiple movements simultaneously and in coordination with each other. That is, when the ankle joint performs inversion, dorsiflexion and adduction movements will also occur at the same time; similarly, when the ankle joint performs eversion, plantar flexion and abduction movements will also occur. The angle range of various movements is determined by the rotation angle of the motor, which can achieve the purpose of the ankle joint's natural movement state and effectively avoid unnecessary injuries.

[0025] In this utility model, such as Figure 1 and Figure 2As shown, the ankle joint training device also includes a control keyboard 4. The control output terminal of the control keyboard 4 is electrically connected to the control terminal of the first motor 311 and the control terminal of the second motor 312. A display screen (not shown) is also provided on the control keyboard 4. Patients can freely set the rehabilitation training time through the control keyboard 4 to control the start and stop duration of the training, making it easier for users to operate and reducing resistance to training caused by operational difficulty. The display screen is used to display the remaining training time.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
