[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present invention.

[0035] As Figures 1 - 4 shown, the present invention provides an ankle rehabilitation training device, including a frame 1, a training platform 2, an ankle training mechanism and a toe training mechanism. The training platform 2 is used to support the foot and is connected to the frame 1 through the ankle training mechanism; the ankle training mechanism drives the training platform 2 to drive the foot to perform dorsiflexion, plantar flexion, inversion and eversion movements; the toe training mechanism is arranged at the position of the training platform 2 corresponding to the toes and is used to drive the toes to perform opening and closing movements.

[0036] The device of the present invention integrates an ankle training mechanism and a toe training mechanism, and can perform ankle and toe training simultaneously or separately. The ankle training mechanism drives the foot to perform active training of dorsiflexion, plantar flexion, inversion and eversion movements, and conducts all-round training on the ankle part. In addition, the toe training mechanism drives the toes to perform opening and closing movement training, improves the flexibility and coordination of the toes, so as to promote the overall recovery of the patient's lower limb function and more comprehensively cover the rehabilitation training needs of the patient.

[0037] Among them, the ankle rehabilitation training device for the left foot and the ankle rehabilitation training device for the right foot are independently arranged, and the structures of the two are symmetrically arranged. Whether the patient's rehabilitation training requirement is single-foot rehabilitation or double-foot simultaneous rehabilitation, the left-foot device, the right-foot device or the double-foot device can be flexibly selected, improving the applicability and practicability of the device.

[0038] As an optional implementation manner, as Figure 1 , Figure 2 , Figure 4As shown in the figure, the ankle training mechanism includes a first training part, a cross shaft 14 and a second training part. The first training part includes a first cylinder 3, a first chute 4, a first rack 5 and a first gear 6. The first cylinder 3 and the first chute 4 are arranged on the frame 1. The output shaft of the first cylinder 3 is connected to the first rack 5. The first rack 5 is slidably matched with the first chute 4 and meshes with the first gear 6.

[0039] The second training part includes a second cylinder 8, a second chute 9, a second rack 10, a second gear 11 and a support base 13. The training platform 2, the second cylinder 8 and the second chute 9 are arranged on the support base 13. The output shaft of the second cylinder 8 is connected to the second rack 10. The second rack 10 is slidably matched with the second chute 9 and meshes with the second gear 11.

[0040] The two horizontal ends of the cross shaft 14 are respectively rotatably connected to the frame 1, and its two vertical ends are respectively rotatably connected to the support base 13. The first gear 6 is arranged on a horizontal end of the cross shaft 14, and the second gear 11 is arranged on a vertical end of the cross shaft 14.

[0041] Further, the central axes of the first rack 5 and the drive shaft of the first cylinder 3, and the central axes of the second rack 10 and the drive shaft of the second cylinder 8 are collinear. The horizontal axis of the cross shaft 14 is perpendicular to the central axis of the first rack 5. The vertical axis of the cross shaft 14 is perpendicular to the central axis of the second rack 10.

[0042] It further includes a control module. The first cylinder 3 and the second cylinder 8 are respectively electrically connected to the control module, and the electrical connection relationship among the three adopts the existing technology and will not be elaborated here.

[0043] When the first cylinder 3 works, its output shaft extends to drive the first rack 5 to slide in the first chute 4 and simultaneously meshes with the first gear 6 for transmission. Since the first gear 6 is arranged on a horizontal end of the cross shaft 14, the cross shaft 14 rotates around its horizontal axis, thereby driving the support base 13 and the training platform 2 to swing up and down, realizing the dorsiflexion action and plantar flexion action of the foot.

[0044] When the second cylinder 8 works, its output shaft extends to drive the second rack 10 to slide in the second chute 9 and simultaneously meshes with the second gear 11 for transmission. Since the second gear 11 is arranged on a vertical end of the cross shaft 14, the cross shaft 14 rotates around its vertical axis, thereby driving the support base 13 and the training platform 2 to swing left and right, realizing the varus action and valgus action of the foot.

[0045] Through the coordinated action of the first training part and the second training part, the training actions can be carried out smoothly and continuously, ensuring the safety of the rehabilitation training.

[0046] According to the needs of rehabilitation training, by adjusting parameters such as the working pressure, speed, and stroke of the first cylinder 3 and the second cylinder 8, various complex movement patterns of the foot can be simulated and trained, improving the pertinence and effectiveness of rehabilitation training.

[0047] As an alternative implementation, the horizontal ends of the cross shaft 14 are respectively rotatably connected to the frame 1 through the first sleeves 7.

[0048] With this setting, the flexibility and stability of the rotation of the cross shaft 14 are increased. At the same time, friction and wear are reduced, and the service life is extended.

[0049] As an alternative implementation, the support base 13 is a U-shaped frame structure, and both ends are respectively rotatably connected to the cross shaft 14 through the second sleeves 12; the training platform 2 is connected to the upper wing plate of the support base 13 through a connecting component.

[0050] With this setting, the support base 13 can provide sufficient structural strength and stability.

[0051] Furthermore, the connecting component includes a connecting sleeve 20 and a connecting column 21. The connecting column 21 is arranged on the upper wing plate of the support base 13, and the connecting sleeve 20 is arranged on the bottom plate of the training platform 2. A limiting protrusion 211 is arranged on the connecting column 21, and a limiting chute adapted to the limiting protrusion 211 is arranged on the connecting sleeve 20. A first connecting hole 212 is arranged on the connecting column 21, and a second connecting hole 201 corresponding to the first connecting hole 212 is arranged on the connecting sleeve 20, and the two are connected by bolts.

[0052] When the connecting sleeve 20 is sleeved on the connecting column 21, the limiting protrusion 211 will slide into the limiting chute, and the second connecting hole 201 corresponds to the first connecting hole 212. By passing a bolt through the two and tightening, the connecting sleeve 20 and the connecting column 21 are firmly connected together, thereby realizing the firm connection between the training platform 2 and the support base 13.

[0053] As an alternative implementation, the second gear 11 is arranged on the lower vertical end of the cross shaft 14, and the second chute 9 is correspondingly arranged on the lower second sleeve 12.

[0054] With this setting, when the second cylinder 8 drives the second rack 10 to slide, the meshing between the second rack 10 and the second gear 11 is more direct and efficient.

[0055] As an alternative implementation, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 shown, on the training platform 2, two side plates 15 are oppositely arranged corresponding to the position of the forefoot to limit the position of the forefoot, and a U-shaped limiting plate 16 is arranged at the rear end of the training platform 2 to limit the position of the heel.

[0056] The side panels 15 are used to limit the left and right movement of the forefoot on the training platform 2 during training, so that the patient's feet can remain on a relatively fixed path when performing dorsiflexion and plantar flexion movements, thereby improving the training effect.

[0057] The design of the U-shaped limiting plate 16 better fits the contour of the heel, limits the sliding of the foot during training, prevents the heel from moving excessively backward during training, and limits the position of the heel to a certain extent, so that the patient's foot can remain on a relatively stable plane when performing inversion and eversion movements, thereby improving the stability and safety of training.

[0058] As an optional implementation, Figure 1 , Figure 2 , Figure 4 As shown, the toe training mechanism includes an opening training part and a closing training part. The opening training part includes four groups of opening airbags 17, which are arranged on the training platform 2 and correspond to the toe gaps one by one; the closing training part includes two groups of closing airbags 18, which are respectively arranged on the inner sides of the side panels 15.

[0059] When the air pump inflates the opening airbag 17, the opening airbag 17 expands and pushes the adjacent toes apart, thereby achieving the toe opening action.

[0060] When the air pump inflates the approaching airbag 18, the approaching airbag 18 expands and pushes the toes to approach inwards, thereby achieving an action of approaching the toes.

[0061] As an optional implementation, the expanding airbag 17 and the closing airbag 18 are connected to an air pump via pipelines.

[0062] Furthermore, the opening airbag 17, the closing airbag 18 and the air pump are electrically connected to the control module, and the specific electrical connection relationship adopts the existing technology, which will not be elaborated here.

[0063] As an optional implementation, Figure 1 , Figure 2 , Figure 4 As shown, it also includes a strap 19, and a limiting groove is opened on the side plate 15. The two free ends of the strap 19 pass through the limiting groove and are detachably connected to each other, and form a limiting space between the training platform 2 and the side plate 15.

[0064] Furthermore, the two free ends of the strap 19 can be connected by a Velcro assembly or a buckle assembly in the prior art, so that the strap 19 is easy to install and remove, and is convenient for the patient to put on and take off before and after use.

[0065] The strap 19 is used to fix the patient's foot on the training platform 2. After the strap 19 passes through the limiting groove and is connected, a limiting space is formed between the training platform 2 and the side plate 15, which can effectively limit the movement range of the foot. During the training process, the foot is in a stable supporting environment, enabling the patient to focus more on the training actions and improving the training effect.

[0066] As an alternative implementation, as Figure 1 , Figure 2 , Figure 4 shown, the diameter of the expanding airbag 17 gradually decreases from both ends to the middle.

[0067] With this setting, when the expanding airbag 17 inflates and expands, the expansion force in the middle is relatively large, while the expansion force at both ends is relatively small.

[0068] Moreover, since the upper part of the expanding airbag 17 has a larger diameter, it can closely cover the roots of the toes, playing a certain limiting role to prevent the toes from detaching from the expanding airbag 17 during the training process, improving the effectiveness and continuity of the training, enabling the patient to continuously perform toe spreading training without interruption due to the slipping of the toes.

[0069] During the rehabilitation training process, when the expanding airbag 17 inflates and expands, the relatively large expansion force in the middle will push the toes to open outwards. At the same time, the upper part of the expanding airbag 17 can limit the toes from slipping out of the expanding airbag 17, making the training more stable and continuous.
