[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] The inventors have found that some devices currently on the market for ankle joint exercise and rehabilitation have many problems. For example, some devices can only drive the foot to perform unidirectional rotation exercise and rehabilitation of the ankle joint through dorsiflexion and plantar flexion. The activity mode is relatively simple and cannot provide the patient's ankle joint with rotation exercise at various angles, which leads to poor rehabilitation effect on the ankle joint. Some devices lack the function of performing targeted adjustments according to the patient's ankle joint recovery condition and have a narrow scope of application. In addition, the structural design of some devices is too complicated, which easily leads to high manufacturing costs and inconvenient disassembly and assembly.

[0024] Based on the above findings, the present application proposes a functional training and rehabilitation device for ankle joint injuries, which drives the foot support plate as a whole to flip at a certain angle in multiple directions through a first electric push rod arranged under the foot support plate and a pair of symmetrically arranged second electric push rods, and drives the drive gear to rotate in combination with a drive motor to drive the fan-shaped support plate to rotate, thereby driving the patient's ankle joint to perform multi-angle rotation exercises, and limits the rotation angle of the fan-shaped support plate in combination with a limiting mechanism to be suitable for patients with different degrees of ankle joint recovery; a hot compress and cold compress massage component is designed, which wraps the ankle joint as a whole through a sleeve airbag located above the foot support plate, and applies cold or hot compress to the ankle joint and calf as a whole in combination with a water bag, and performs rotational massage on the ankle joint and calf as a whole through massage beads evenly distributed on the surface of the water bag; it has the advantages of good recovery effect, good safety, comprehensive functions and simple structure.

[0025] See also Figure 1-Figure 6 ,as well as Fig.13 and Fig.14 The present application discloses a functional training and rehabilitation device for ankle joint injury, comprising a seat 1 and a bottom support plate 2 rotatably arranged under the seat 1. The seat 1 is made of a metal material with relatively high strength as a whole, and a soft pad structure can be arranged on its surface to enhance the user experience of the patient. In some embodiments, a group of connecting block structures are rotatably installed on a side of the seat 1 away from the backrest by means of a rotating shaft. The bottom support plate 2 is fixed to each individual connecting block structure by two retractable connecting rods 6. The bottom support plate 2 is made of a metal material with relatively high strength as a whole. As shown in the accompanying drawings, the structure thereof can be regarded as comprising a horizontal plate surface, one side of which is provided with a columnar structure fixed to the connecting rod 6, and a reinforcing crossbeam is also arranged between the two columnar structures. See also Figure 7 The bottom support plate 2 is provided with an ankle joint exercise component 4 for ankle joint exercise and rehabilitation, and the ankle joint exercise component 4 includes a first electric push rod 401 vertically fixed at the center of the bottom support plate 2 and second electric push rods 402 on both sides, the movable end at the top of the first electric push rod 401 is rotatably connected to the center of the bottom of the foot support plate 3, and the movable end at the top of the second electric push rod 402 is rotatably connected to both sides of the bottom of the foot support plate 3; Specifically, the foot support plate 3 is located directly above the bottom support plate 2, and the foot support plate 3 is a plate structure with good strength and capable of certain elastic deformation. The first electric push rod 401 and the two second electric push rods 402 are electric push rod products made of metal, which are vertically fixed to the bottom support plate 2 by bolt connection and other means. In some implementation schemes, the top movable end of the first electric push rod 401 is provided with a ball joint structure, and a spherical mounting hole capable of clamping the ball joint structure is provided at the bottom center of the foot support plate 3. At the same time, the top movable ends of the two second electric push rods 402 are fixed with mounting blocks with transverse cylindrical through holes, and cylindrical The rotating shaft is connected to the mounting block so that the foot support plate 3 can rotate relative to the second electric push rods 402 on both sides. When the first electric push rod 401 is extended or shortened, since the two sides of one end of the foot support plate 3 are rotatably connected to the two second electric push rods 402, the foot support plate 3 can be rotated to the rear or front relative to the patient in the sitting state. At the same time, since the foot support plate 3 can undergo a certain elastic deformation, when the second electric push rods 402 on both sides are extended or shortened respectively, the foot support plate 3 can be flipped to the left or right. Through the cooperation of the first electric push rod 401 and the second electric push rod 402, the foot support plate 3 can be vertically flipped in all directions. The foot support plate 3 is also rotatably provided with a fan-shaped support plate 403 with a rack structure, and the foot support plate 3 is also provided with a driving motor 404, and the power output end of the driving motor 404 is fixed with a driving gear 405 meshingly connected with the rack structure of the fan-shaped support plate 403. Specifically, the fan-shaped support plate 403 is a flat fan-shaped metal plate structure. In some embodiments, a rotating column structure is fixed at the bottom thereof, and a cylindrical through hole is opened on one side above the foot support plate 3 and close to the two ends where the cylindrical rotating shaft is fixed. Then, the fan-shaped support plate 403 is provided with a cylindrical through hole. 03 can be rotatably fixed on the foot support plate 3 by means of a snap connection. A driving motor 404 is fixed on the foot support plate 3 and away from the side where the cylindrical rotating shafts are fixed at both ends. The power output shaft of the driving motor 404 is vertically upward and is fixed with a driving gear 405. The driving gear 405 has the same horizontal height as the fan-shaped support plate 403, and the driving gear 405 is meshed with the rack structure on the fan-shaped support plate 403. When the driving motor 404 drives the driving gear 405 to rotate, the fan-shaped support plate 403 can be driven to rotate. See also Fig.12In some embodiments, one or more elastic straps 409 for binding and fixing the patient's foot are also provided on the fan-shaped support plate 403. When the patient fixes the foot as a whole to the fan-shaped support plate 403, the foot support plate 3 and the fan-shaped support plate 403 can be turned over as a whole through the extension and contraction of the first electric push rod 401 and the second electric push rod 402, and the fan-shaped support plate 403 can be driven to rotate in cooperation with the driving motor 404, thereby providing the patient's ankle joint with all-round rotation exercise at various angles to improve the recovery speed of the patient's ankle joint; in addition, a plurality of arc-shaped installation grooves 408 are provided on the fan-shaped support plate 403, and a plurality of foot massage rollers 407 are rotatably fixed in the installation grooves 408. The foot massage rollers 407 can massage various acupuncture points on the sole of the patient's foot, and the patient can also choose to step on the fan-shaped support plate 403 and rotate the foot autonomously to perform rolling massage on the sole of the foot; See also Figure 8 The foot support plate 3 is also provided with a limiting mechanism 406 for limiting the fan-shaped support plate 403. The limiting mechanism 406 includes a hydraulic push rod 4061 located at the bottom of the foot support plate 403. One side of the foot support plate 3 is provided with a three-way piston chamber 4062 connected to the hydraulic push rod 4061. In some embodiments, the fixed end of the hydraulic push rod 4061 is fixed to the bottom of the foot support plate 403 by bolt connection or the like, and the movable end of the other end thereof is inserted into the middle through hole of the three-way piston chamber 4062. The three-way piston chamber 4062 is fixed to the side of the foot support plate 3 close to the drive motor 404 through the fixed block in the middle and the fixed block structure sleeved on the pipes at both ends. The two ends of the three-way piston chamber 4062 are slidably provided with The limiting piston rod 4063 that can be contacted by the fan-shaped support plate 403 can simultaneously push out or pull in the limiting piston rods 4063 at both ends of the three-way piston chamber 4062 through the action of air pressure when the hydraulic push rod 4061 is extended or shortened. When the limiting piston rod 4063 is pushed out, the rotation range of the fan-shaped support plate 403 can be increased, otherwise the rotation range of the fan-shaped support plate 403 can be reduced. By limiting the rotation range of the fan-shaped support plate 403 through the limiting mechanism 406, it is possible to prevent the fan-shaped support plate 403 from rotating too much, thereby preventing sprains to the patient's ankle joint. Conversely, by adjusting the position of the limiting piston rod 4063, customized adjustment can be provided for patients according to the different degrees of recovery of the ankle joints of different patients.

[0026] In some embodiments, a ball joint structure can be selected for connection between the second electric push rod 402 and the foot support plate 3. For example, the cylindrical shaft structure at both ends of the foot support plate 3 is replaced with a spherical structure, and a fixed block that can clamp the spherical structure is provided at the upper end of the second electric push rod 402, so that the foot support plate 3 can be flipped without deformation as the first electric push rod 401 and the second electric push rod 402 extend and retract.

A water bag 503 is rotatably arranged on the sleeve airbag 501. In some embodiments, the water bag 503 is a hollow cylindrical structure with good elasticity. An annular track can be optionally arranged near the upper end and the lower end of the sleeve airbag 501, and an annular depression matching the track is opened near the upper and lower ends of the water bag 503, so that the water bag 503 can be rotatably installed in the sleeve airbag 501. At the same time, a plurality of massage beads 506 are evenly distributed on the inner surface of the water bag 503. When the water bag 503 rotates relative to the sleeve airbag 501, the massage beads 506 can also massage the patient's calf. Combined with the foot massage roller 407 in the above content, it can also improve the blood circulation in the patient's calf and ankle joints to improve the recovery effect of the ankle joint.

The second water pipe 509 passes through the through groove structure and is connected to the water pump 504 through the water bag adjustment mechanism 505. In addition, in the embodiments of the present invention, the air pipe 508 and the second water pipe 509 are both pipes with certain strength and good elasticity, and can be deformed to a certain extent with the movement of other structures without being damaged.

[0029] See also Fig. 9as well as Fig.10 The foot support plate 3 is also provided with a water bag adjustment mechanism 505, and the water bag adjustment mechanism 505 includes a fixing frame 5051 located above and below the foot support plate 3. In some embodiments, the fixing frame 5051 can be regarded as a double-layer bracket structure, which is fixed above or below the foot support plate 3 by being clamped to the bottom position of the connecting rod 6 or the columnar structure of the bottom support plate 2; The fixing frame 5051 is provided with a rotatable adjusting gear 5052 on the bracket structure located at the upper part or the lower part, and the fixing frame 5051 is provided with an adjusting rack 5053 on the bracket structure located at the lower part or the upper part, one end of which is meshed and connected with the adjusting gear 5052, which means that the adjusting gear 5052 and the adjusting rack 5053 can be arranged according to the specific position of the fixing frame 5051; In some embodiments, the adjustment rack 5053 can be regarded as an L-shaped structure as a whole, and a longer section thereof is provided with a plurality of tooth structures that match the adjustment gear 5052, and the section is slidably set on the fixing frame 5051 by means of a snap connection. In this embodiment, an elastic link 5056 is provided between the adjustment rack 5053 and the fixing frame 5051, that is, a slender telescopic rod structure with a spring fixed inside. When the adjustment rack 5053 slides laterally along the fixing frame 5051, it can drive the adjustment gear 5052 to rotate and stretch or compress the elastic link 5056. At the same time, a rectangular through groove with a width greater than the adjustment rack 5053 is provided on one side of the foot support plate 3. The shorter end of the adjustment rack 5053 vertically penetrates into the rectangular through groove. When the foot support plate 3 rotates, it can just contact and push the adjustment rack 5053 to slide along the fixing frame 5051, thereby driving the adjustment gear 5052 to rotate. It should be noted that, since the width of the rectangular through groove on the foot support plate 3 is greater than the overall width of the adjustment rack 5053, when the foot support plate 3 is flipped to the left or right, etc., it will not affect the normal sliding of the adjustment rack 5053; in addition, in some embodiments, a pushing block structure for pushing the adjustment rack 5053 can be optionally provided on the foot support plate 3 and directly opposite the adjustment rack 5053 located above it, so that when the foot support plate 3 is flipped upward or downward, it can trigger the adjustment rack 5053 above or below it to slide; at the same time, when the limiting mechanism 406 allows a larger rotation range of the fan-shaped support plate 403, the rotation of the fan-shaped support plate 403 can also drive the adjustment rack 5053 located below to slide horizontally.

[0030] A water storage container 5054 is also provided on one side of the fixing frame 5051, which is connected to the water pump 504 through the first water delivery pipe 507.

The air pump 502 is used to inflate the sleeve airbag 501. The elastic bandage 409 is used to fix the patient's foot and the fan-shaped support plate 403. The water pump 504 is used to transport cold water for cold compress or hot water for hot compress into the water bag 503. S2, by respectively controlling the first electric push rod 401 or the second electric push rod 402 to extend and retract, so as to drive the foot support plate 3 and the fan-shaped support plate 403 to rotate as a whole, or starting the driving motor 404, and driving the fan-shaped support plate 403 to rotate through the driving gear 405, so as to perform multi-angle rotation exercise on the patient's ankle joint; S3, when the foot support plate 3 rotates, it can push the adjustment rack 5053 to slide, and the adjustment gear 5052 rotates to drive the stirring roller 5055 to rotate, thereby stirring the water in the water storage container 5054 to accelerate the flow rate of the water in the water bag 503, so as to ensure that the ankle joint is evenly cold or hot; S4. By controlling the extension and retraction of the hydraulic push rod 4061, the limit piston rods 4063 at both ends of the three-way piston chamber 4062 are driven to adjust the rotation range of the fan-shaped support plate 403 to adjust for patients with different degrees of recovery of the ankle joint.

[0033] Practical application cases According to the degree of recovery of the patient's ankle joint, the hydraulic push rod 4061 is controlled to control the push-out length of the limit piston rod 4063, and the maximum rotation angle of the fan-shaped support plate 403 is adjusted. After the adjustment is completed, the patient sits on the seat 1, and extends the foot downward along the sleeve airbag 501, and contacts the sole of the foot with the fan-shaped support plate 403, and then uses the air pump 502 to inflate the sleeve airbag 501 until the sleeve airbag 501 and the water bag 503 can wrap the patient's calf and ankle joint, and uses the elastic bandage 409 to fix the patient's foot to the fan-shaped support plate 403; The first electric push rod 401 and the second electric push rod 402 are started to drive the foot support plate 3 and the fan-shaped support plate 403 to rotate as a whole, and the driving motor 404 is started to drive the fan-shaped support plate 403 to rotate at the maximum rotation angle allowed by the limit piston rod 4063, so as to drive the patient's ankle joint to exercise and recover, and the sole of the foot is massaged by the foot massage roller 407 on the fan-shaped support plate 403, and the patient's calf is massaged by the massage beads 506 inside the water bag 503; The water pump 504 is used to transport water for cold compress or hot compress into the water bag 503. When the foot support plate 3 is flipped in an upward or downward direction, it can push the adjustment rack 5053 and drive the adjustment gear 5052 to rotate, so that the temperature of the water in the water bag 503 is evenly distributed.
