[0051] See also Figure 1-Figure 5 In this embodiment, the swing guide mechanism includes a crank rotating shaft 10, a crank 4, a rotating sub-connecting rod 5, a first slider 6, a first slide rail 8 and a pedal 7. The first slide rail 8 is arranged on the back of the pedal 7 along the length direction of the pedal 7. The first slider 6 is slidably installed in the first slide rail 8. One end of the rotating sub-connecting rod 5 is connected to the top of the first slider 6. The other end of the rotating sub-connecting rod 5 is rotatably connected to one end of the crank 4.

One end of each rotating sub-connecting rod 5 is connected to the top end of the first slider 6 on the same side, and the other end of each rotating sub-connecting rod 5 is rotatably connected to one end of the crank 4 on the same side, and the other end of each crank 4 is connected and fixed to the end of the crank rotating shaft 10 on the same side, and a rotating pair is formed between the base 1 and the pedal 7.

[0052] See also Figure 1-Figure 5 In this embodiment, the swing guide rod mechanism also includes a U-shaped connector 14, one end of the U-shaped connector 14 is connected to the top of the first slider 6, and the side wall where the other end of the U-shaped connector 14 is located is connected to one end of the rotating secondary connecting rod 5.

[0053] See also Figure 1-Figure 5 In this embodiment, a U-shaped support plate 2 and a leg pad 15 are respectively provided on both sides of the rotating shaft support component on the base 1. The bottom of the U-shaped support plate 2 is fixed to the base 1, and a rotation pair is formed between the top of the U-shaped support plate 2 and the pedal 7; the leg pad 15 is located on one side of the tread of the pedal 7 and is used to support the legs during ankle training.

[0054] See also Figure 1-Figure 5 In this embodiment, the bottom end of the rotary shaft support component and the left end of the base (with Figure 1 The described rotation axis support component includes a housing 9, a controller 26 and a driving device, the controller 26 and the driving device are arranged in the housing 9, the crankshaft 10 is connected to the driving device, and the controller 26 is connected to the driving device. As an example, the driving device can be, for example, a motor, or a combination of a motor and a reducer, or a flywheel. It should be noted that in other embodiments, the controller 26 can also be arranged at other suitable positions of the ankle training device.

[0055] See also Figure 1-Figure 5In this embodiment, the first adjusting mechanism is arranged between the rotating shaft support component and the base 1 of the base, and a moving pair is formed between the rotating shaft support component and the base 1. At the same time, the rotating shaft support component and the first end of the base 1 form a rotating pair. The relative position of the crank rotating shaft 10 and the first end of the base 1 can be adjusted by the first adjusting mechanism (including the overall horizontal movement of the rotating shaft support component, or adjusting the vertical distance between the crank rotating shaft 10 and the base 1) to adjust the swing angle of the pedal 7. The first adjustment mechanism includes a support plate 3 and a second slide rail 11, the rotary axis support component is slidably mounted on the second slide rail 11 and can be locked; the second slide rail 11 is arranged on the base 1 along the length direction of the base 1; the rotary axis support component and the top of the third slider can be connected by a hinge 17 to realize the rotational connection between the rotary axis support component and the third slider; the two ends of the support plate 3 are respectively provided with a rotation pair, one end of the support plate 3 is connected to the middle part of the rotary axis support component through a rotation pair, and the other end of the support plate 3 is connected to the second slider through a rotation pair, and the second slider is slidably mounted on the second slide rail 11, that is, the other end of the support plate 3 is slidably mounted on the second slide rail 11 through the second slider. Therefore, using Figure 1-Figure 5 The first adjustment structure can adjust the horizontal movement of the rotating shaft support component by the synchronous movement of the box body 9 of the rotating shaft support component and the support plate 3 along the second slide rail 11, and can also adjust the angle between the base 1 and the box body 9 by fixing the box body 9 of the rotating shaft support component and moving the support plate 3 along the second slide rail 11. Both of them will cause the position of the crank rotating shaft 10 to change, thereby achieving the purpose of adjusting the swing angle of the pedal 7 of the swing guide rod mechanism.

[0056] It is understandable that, in one embodiment, when there is no need to change the angle between the adjustment base 1 and the box 9, and only the horizontal movement of the box 9 of the rotary shaft support component is adjusted, the following method can also be used. Figure 6 As shown, a rotation pair is not provided at both ends of the support plate 3 of the first adjustment mechanism. One end of the support plate 3 and the middle part of the driving device can be fixed by bolt connection or welding. The other end of the support plate 3 is slidably mounted on the second slide rail 11 through a second slider (not shown). The end of the housing 9 of the rotary shaft support component away from the crank rotary shaft 10 is mounted on the second slide rail 11 through a third slider (not shown), that is, a moving pair is formed between the rotary shaft support component and the base 1 instead of a rotation pair. The rotary shaft support component is adjusted to move horizontally by the synchronous movement of the housing 9 of the rotary shaft support component and the support plate 3 along the second slide rail 11. The horizontal movement of the rotary shaft support component will cause the position of the crank rotary shaft 10 to change, thereby achieving the purpose of adjusting the swing angle of the pedal 7 of the swing guide rod mechanism.

[0057] It is understandable that in another embodiment, when only the angle between the base 1 and the box 9 needs to be changed and adjusted, and the box 9 of the rotating shaft support component is not in a horizontal position, only a revolute pair needs to be formed between the bottom end of the box 9 and the base 1. Figure 7 The ball screw mechanism 23 shown in the figure is used as the first adjustment mechanism, or the Figure 8 The first electric push rod 24 shown is used as the first adjustment mechanism to adjust the angle between the base 1 and the box 9. Of course, a length-adjustable rod mechanism, a support plate positioning slot mechanism or a support plate positioning hole mechanism can also be used as the first adjustment mechanism to adjust the angle between the base 1 and the box 9; wherein the length-adjustable rod mechanism is composed of two sections of rod bodies and a locking member, and is adjusted by changing the overlapping length of the two sections of the length-adjustable rod mechanism; the support plate positioning slot mechanism is adjusted by an inclined support plate and a long strip positioning slot provided on the box 9 or the base 1; the support plate positioning hole mechanism is adjusted by an inclined support plate and a plurality of positioning holes provided on the box 9 or the base 1.

[0058] See also Figure 4 and Figure 5 As shown, in this embodiment, the rotary shaft support component further includes a resistance component disposed in the box 9, and the resistance component includes a friction component, a magnetically controlled resistance generator or a flywheel. Figure 4 As shown, the resistance component adopts a friction assembly, which includes a friction plate 19 and a friction plate seat 18 that cooperate with each other. The friction plate 19 is installed on the crank shaft 10, and the friction plate seat 18 is installed on one end of the box body 9 close to the crank shaft 10. The movement resistance is adjusted by operating the human-machine interaction device 12 to be introduced later to control the controller 26 to tighten or loosen the friction plate 19 and the friction plate seat 18. Figure 5 As shown, the resistance component adopts a magnetron resistance generator, and the magnetron resistance generator includes an aluminum disk 21 flywheel and a permanent magnet 20 assembly that cooperate with each other. The aluminum disk 21 flywheel is installed on the crank rotating shaft 10, and the permanent magnet 20 assembly is installed at one end of the box body 9 close to the crank rotating shaft 10. The permanent magnet 20 and the aluminum disk 21 constitute the aluminum disk 21 flywheel of the magnetron resistance generator. The flywheel cuts the magnetic flux lines between the permanent magnets 20 to generate eddy currents to form resistance. The resistance can be adjusted by operating the human-computer interaction device 12 to control the controller 26 to adjust the distance between the aluminum disk 21 and the permanent magnet 20.

[0059] It should be noted that in other embodiments, a friction assembly or a magnetically controlled resistance generator may not be specially provided as a resistance component, but a driving device may be directly used as a resistance component. Taking a driving device using a motor or a motor and a reducer as an example, a direct current not greater than the rated current of the motor may be input to the motor, so that the motor is in an energy-consuming braking state and becomes a resistance source.

[0060] See also Figure 1-Figure 5 In this embodiment, the length of the crank 4 is adjustable, and the length of the crank 4 can be adjusted to assist in adjusting the inclination angle of the pedal 7. The length adjustment of the crank 4 can be achieved by replacing the crank 4 with different length specifications.

[0061] It should be noted that, in this embodiment, the crank may also be, for example, a rotating disk.

[0062] See also Figure 1-Figure 5 In this embodiment, the ankle training device further includes a human-machine interaction device 12, which can be disposed on the top surface of the box 9, and can be connected to the controller 26. As an example, the human-machine interaction device 12 can be a remote control or a touch screen.

[0063] When using the ankle training device of this embodiment, the user can sit or lie down. The first adjustment mechanism can be used to adjust the position of the swing guide mechanism to adjust the swing angle of the pedal 7, or the second adjustment mechanism can be used to adjust the distance between the base 1 and the bottom plate 13, or the length of the crank 4 can be adjusted to adjust the inclination angle of the pedal 7, so as to meet the reasonable ankle joint movement range and angle of different human bodies.

[0064] The ankle training device of this embodiment may include three training modes, namely, a passive prevention training mode, an assisted prevention training mode and an active prevention training mode.

[0065] During passive prevention training, the power source all comes from the driving device. The foot is located on the pedal 7. The driving device drives the crank 4 to rotate, driving the pedal 7 of the swing guide rod mechanism to move. The pedal 7 drives the ankle to swing back and forth. The driving device can specifically be a motor or a combination of a motor and a reducer. When the human-computer interaction device 12 is operated, the controller 26 receives a signal to control the motor speed to achieve graded regulation.

[0066] During assisted prevention training, which is between passive prevention training and active prevention training, part of the power source comes from the drive device and part comes from the human foot. The human-computer interaction device 12 is operated to enable the controller 26 to control the drive device to switch to assisted prevention training mode. The intelligent sensing system (including sensors and control circuits) of the controller 26 is started, and the assisted training is completed in cooperation with the human ankle to activate the lower limb muscles and promote blood flow in the feet.

[0067] During active prevention training, the human foot is the power source, driving the pedal 7 of the swing guide mechanism to move. The training resistance can be set by adjusting the human-machine interaction device 12 to control the controller 26. The resistance component can be a motor or a motor and a reducer combination component or a friction component or a magnetic control resistance generator or a flywheel and other devices. When the motor or the motor and the reducer combination component is used as the resistance component, a direct current not greater than the rated current of the motor is input to the motor, so that the motor is in an energy consumption braking state and becomes a resistance source; Figure 4 The friction plate holder 18 and the friction plate 19 constitute the resistance component, and the movement resistance is adjusted by operating the human-machine interaction device 12 to control the controller 26 to tighten or loosen the friction plate 19 and the friction plate holder 18; Figure 5 The permanent magnet 20 and the aluminum disk 21 form the aluminum disk 21 flywheel of the magnetic control resistance generator, which cuts the magnetic flux lines between the permanent magnets 20 to generate eddy currents to form resistance. The distance between the aluminum disk 21 and the permanent magnet 20 can be adjusted by operating the human-machine interaction device 12 to control the controller 26 to adjust the resistance. Different resistances can activate the human foot muscle movement to different degrees, and graded exercise can promote blood circulation.

[0068] In summary, the ankle training device of the present invention adopts a swinging guide rod mechanism, which can better adapt to the movement law of the human ankle, realize ankle pump movement, promote blood flow in the foot, and reduce blood coagulation into emboli. The ankle training device of the present invention is specifically aimed at the exercise training of the ankle joint muscle group, has no obvious effect on other parts of the lower limbs of the human body, and is more suitable for people who are inconvenient to exercise the knee or hip joints. The slider of the swinging guide rod mechanism of the ankle training device of the present invention can move on the second slide rail, and has good stability. The ankle training device of the present invention can adjust the relative position of the crank rotating shaft and the base through the first adjustment mechanism to adjust the swing angle of the pedal 7, and / or the relative position of the crank rotating shaft and the bottom plate can be adjusted through the second adjustment mechanism, or the length of the crank 4 can be adjusted at the same time to achieve the adjustment of the inclination angle of the pedal 7, and at the same time meet the reasonable ankle joint movement amplitude and angle of different human bodies. The ankle training device of the present invention has little interference with the original normal state of human muscles or pulses, is not prone to arterial ischemia or venous blood reflux, and has no obvious side effects.
