[0055] See also Figure 1-5 As shown, an embodiment of the present invention provides an ankle joint rehabilitation trainer, which includes a support frame 10, an adjustable support frame 20, a leg support 30, a foot support bracket 40 and a foot support 50, wherein:

[0056] The adjustable support frame 20 is vertically connected to the support frame 10; the leg rest 30 is located on one side of the support frame 10, and the leg rest 30 is fixed to the top end of the adjustable support frame 20; the foot rest bracket 40 is horizontally fixed to the bottom end of the adjustable support frame 20; a top corner of the foot rest 50 is hinged to the end of the foot rest bracket 40 away from the foot rest bracket 40, so that the foot rest 50 can rotate at an up and down angle.

[0057] When using the above-mentioned ankle joint rehabilitation trainer, the patient places the sole of the foot on the foot rest 50 and leans the calf on the leg rest 30, so that the foot and calf are respectively attached to the foot rest 50 and the leg rest 30, and the height of the foot rest bracket 40 is adjusted according to the individual calf length to move the foot rest 50 to the appropriate position; then the setting parameters are input into the angle feedback component 43, so that the remote control 431 lifts or releases the foot rest 50 according to the setting parameters input by the user, so that the foot rest 50 rotates at an ups and downs angle. In this process, by changing the angle between the patient's instep and calf, rehabilitation training of the patient's ankle is achieved. The above-mentioned ankle joint rehabilitation trainer can be used independently at home, and the user can set the parameters individually according to the patient's condition, so as to perform rehabilitation training for the patient.

[0058] For further information, see Figure 1 As shown, the support frame 10 includes a bottom frame 11 and two support beam assemblies 12, wherein:

[0059] The two support beam assemblies 12 are respectively connected horizontally and parallel to the bottom frame 11. Each support beam assembly 12 includes a horizontal support rod 121 and a support seat 122 rotatably connected to both ends of the horizontal support rod 121. The end of the support seat 122 away from the horizontal support rod 121 is fixedly connected to the bottom frame 11.

[0060] For further information, see Figure 1 As shown, the adjustable support frame 20 includes two sliding blocks 21, a vertical rod 22, an adjustable telescopic seat 23 and an adjustable sliding seat 24, wherein:

[0061] The two sliding blocks 21 are respectively slidably connected to the two horizontal support rods 121; the vertical rod 22 is connected to the side of the two sliding blocks 21 away from the bottom frame 11, and is perpendicular to the horizontal support rod 121; the adjustable telescopic seat 23 is horizontally connected to the top of the vertical rod 22, and the end of the adjustable telescopic seat 23 away from the vertical rod 22 is supported and connected to the back of the leg rest 30; the adjustable sliding seat 24 is connected between the horizontal support rod 121 and the foot rest bracket 40.

[0062] For further information, see Figure 1 As shown, the footrest bracket 40 includes a first bracket 41, a second bracket 42 and an angle feedback assembly 43. The first bracket 41 and the second bracket 42 both have sufficient connection strength, wherein:

[0063] One end of the first bracket 41 is fixed to the end of the adjustable sliding seat 24; the second bracket 42 is connected to the end of the first bracket 41 away from the adjustable sliding seat 24; the angle feedback component 43 is installed on the side of the second bracket 42 away from the first bracket 41, for obtaining the rotation angle of the footrest 50.

[0064] Specifically, since the age, calf length and thickness of patients are different, the fixed position footrest bracket 40 cannot adjust the length of the footrest 50, and cannot make the footrest 50 fit the patient's calf better. This will affect the activity effect of the patient's ankle joint during rehabilitation training, which is not conducive to the patient's ankle joint rehabilitation training.

[0065] Please note that Figure 6 As shown, the angle feedback component 43 is provided with a rotating motor 432 and an angle detection sensor 433, wherein the output shaft of the rotating motor 432 is connected to the connecting shaft on the side of the footrest 50, and the rotating motor 432 drives the footrest 50 to swing around the connecting shaft within a certain angle range, and the angle detection sensor 433 detects the rotation angle of the footrest 50, so that the footrest 50 relative to the horizontal direction is between θ1 = -40 degrees and θ2 = +80 degrees (as shown in the attached figure). Figure 3 As shown in FIG, the foot rest 50 is swung inwardly, thereby causing the sole of the foot placed in the foot rest 50 to swing along with the foot rest 50. Since the angle feedback component 43 is an existing mature technology, the working principle of the angle feedback component 43 will not be further elaborated herein.

[0066] For further information, see Figure 1 As shown, the adjustable telescopic seat 23 includes a first square sleeve 231 and a second square sleeve 232, wherein:

[0067] The first square sleeve 231 is horizontally connected to the top of the vertical rod 22; one end of the second square sleeve 232 close to the first square sleeve 231 is suitable for being inserted into the first square sleeve 231, and the other end is connected to the back of the leg support 30; a through hole is provided on the side wall of the first square sleeve 231, and a plurality of positioning holes are provided on the second square sleeve 232 at intervals along the central axis direction, and the positioning holes and the through holes are suitable for being moved and overlapped along the central axis direction.

[0068] It should be noted that, taking into account the different characteristics of different patients' legs, in order to fine-tune the fit between the patient's legs and the leg rest 30, the vertical inclination angle of the leg rest 30 can be fine-tuned through the adjustable telescopic seat 23 to make the patient's legs comfortable when placed in the leg rest 30.

[0069] Specifically, when adjusting the leg support 30, the second square sleeve 232 is dragged to move along the central axis direction of the first square sleeve 231 and stop at an appropriate height. Since a through hole is provided on the side wall of the first square sleeve 231, a plurality of spaced positioning holes are provided on the second square sleeve 232, and the central axis direction of the positioning holes is parallel to the central axis direction of the through hole, when the second square sleeve 232 is moved to an appropriate position, there is always a positioning hole on it that is opposite to or close to the through hole. At this time, the position of the leg support 30 can be fixed by inserting fasteners into the through hole and the positioning hole opposite to or close to the through hole in turn.

[0070] For further information, see Figure 1 As shown, the adjustable sliding seat 24 includes a horizontal short rod 241 and a horizontal sliding locking component 242, wherein:

[0071] The horizontal short rod 241 is located parallel to the front of the horizontal support rod 121 and is vertically symmetrically connected to the end of the vertical rod 22 away from the adjustable telescopic seat 23;

[0072] The horizontal sliding locking component 242 includes a clamping block 2421 and a locking threaded rod 2422. The clamping block 2421 is passed through the horizontal support rod 121, and the locking threaded rod 2422 is rotatably connected to one side of the clamping block 2421. The locking threaded rod 2422 is suitable for rotating to lock or release the clamping block 2421, thereby adjusting the position of the adjustable sliding seat 24 on the horizontal support rod 121.

[0073] Thus, the horizontal position of the footrest 50 relative to the patient can be adjusted as needed, thereby facilitating the patient's rehabilitation training for the left and right legs.

[0074] For further information, see Figure 1 As shown, the footrest 50 is a flat plate structure, one side of which has a limiting slot adapted to the sole of the patient's foot, and one side of the footrest 50 is hinged to the end of the second bracket 42 away from the first bracket 41.

[0075] For further information, see Figure 1 As shown, the leg support 30 includes an arc-shaped plate 31 and a plurality of locking belts 32 , wherein: the arc-shaped plate 31 is connected to the end of the second square sleeve 232 away from the first square sleeve 231 ; and the plurality of locking belts 32 are evenly arranged on both sides of the arc-shaped plate 31 .

[0076] Thus, the arc-shaped plate-like structure is used to limit the position of the patient's calf. In addition, one side of the footrest 50 is hinged to the end of the second bracket 42, and the hinge axis of the two is horizontal. The rotation angle between the two is adjustable within 0 to 360 degrees. When the patient's ankle joint moves with the rotation of the footrest 50, the footrest 50 can also rotate within a certain range. This allows the patient's leg to be adjusted according to the ankle joint posture during training during ankle rehabilitation training, making the trainer more applicable.

[0077] For further information, see Figure 1 As shown, the angle feedback component 43 further includes a remote controller 431 , which is in communication with the angle feedback component 43 and is used to send instructions to the angle feedback component 43 to control the angle feedback component 43 to rotate to a set angle.

[0078] In one embodiment, the angle feedback component 43 further includes a remote controller 431 , which is in communication with the angle feedback component 43 and configured to send instructions to the angle feedback component 43 so as to control the adjustment of the angle feedback component 43 .

[0079] For further information, see Figure 1 As shown, the angle feedback component 43 also includes a power adapter, which is connected to the network power supply and the power output unit.

[0080] Specific usage process: When starting to use, place the support frame 10 vertically in the air and at a certain distance from the ground, wherein the side of the support frame 10 facing away from the support beam assembly 12 is fixed on a support (such as a chair leg, etc.), and the side of the support frame 10 with the support beam assembly 12 is facing outward, and the positions of the footrest 50 and the legrest 30 relative to the patient's left and right legs are adjusted by the adjustable sliding seat 24. After reaching the appropriate position, put one leg of the patient on it, wherein the leg fits into the leg rest 30 and is locked with the locking belt 32, and the sole of the foot is placed in the footrest 50 and locked with the locking belt, start the remote control 431, send instructions to the motor in the angle feedback assembly 43, and control the motor to move according to the set angle, thereby realizing reciprocating motion training of the ankle.
