DETAILED DESCRIPTION

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Example 1 Reference Figure 1-12 , which is the first embodiment of the present invention, provides an intelligent ankle fracture rehabilitation training device, including a training mechanism 100, which includes a seat 101 and a leg limiting plate 102. The upper end of the leg limiting plate 102 is hinged to the seat 101 through a pin shaft. When the patient sits on the seat 101, the patient puts the legs into the leg limiting plate 102. At this time, the patient's legs are limited by the leg limiting plate 102, thereby reducing the possibility that the patient's leg shaking during ankle rehabilitation training affects the rehabilitation training effect.

[0035] The leg limiting plate 102 is connected to the ankle limiting plate 103 by setting a telescopic plate 103a. A slot for plugging the telescopic plate 103a is opened at one end of the leg limiting plate 102 facing the ankle limiting plate 103. One end of the telescopic plate 103a is fixedly connected to the ankle limiting plate 103, and the other end of the telescopic plate 103a is inserted into the slot. When the ankle limiting plate 103 moves, the telescopic plate 103a increases the stability of the ankle limiting plate 103 when moving.

[0036] An adjusting member 105 is fixedly provided on the back of the leg limiting plate 102, and the telescopic shaft of the adjusting member 105 is fixedly connected to the back of the ankle limiting plate 103. The adjusting member 105 includes a first electric push rod 105a, which is fixedly connected to the back of the ankle limiting plate 103. The protruding end of the first electric push rod 105a is fixedly connected to a fixing block 105b, and the fixing block 105b is fixedly connected to the back of the leg limiting plate 102. When the first electric push rod 105a contracts, it drives the fixing block 105b and the ankle limiting plate 103 to move, thereby reducing the distance between the ankle limiting plate 103 and the leg limiting plate 102. Conversely, when the first electric push rod 105a is expanded, it drives the fixing block 105b and the ankle limiting plate 103 to move, thereby increasing the distance between the ankle limiting plate 103 and the leg limiting plate 102. Therefore, the device can be intelligently adjusted for patients of different heights, thereby enabling the device to be suitable for people of different heights.

[0037] A foot limiting plate 104 is provided at one end of the ankle limiting plate 103 away from the leg limiting plate 102, and the foot limiting plate 104 and the ankle limiting plate 103 are hinged via a hinge shaft, so that the foot limiting plate 104 can swing up and down, and when the foot limiting plate 104 swings up and down, the patient's foot is driven to swing at the same time, thereby moving the patient's ankle joint.

[0038] A winding roller 106 is rotatably arranged in the seat 101, and a motor 107 for driving the winding roller 106 is arranged on the seat 101, and a rotating shaft of the motor 107 is inserted into the seat 101 and fixedly connected to one end of the winding roller 106, and a first steel cable 108 is wound around the winding roller 106, and the first steel cable 108 passes through the leg limit plate 102 and the ankle limit plate 103 in sequence and is fixedly connected to the foot limit plate 104, and the first steel cable 108 is used to pull the foot limit plate 104 for deflection. When the operator starts the motor 107, the winding roller 106 is driven by the motor 107 to rotate in the opposite direction and the first steel cable 108 is reeled up, and at this time, the first steel cable 108 pulls the foot limit plate 104 to deflect downward, and as the foot limit plate 104 deflects, the patient's foot is deflected and the ankle joint is moved.

[0039] The ankle limit plate 103 is in a U-shape. Both the ankle limit plate 103 and the foot limit plate 104 have two side plates and a bottom plate. Two arc grooves 109 are provided on the inner sides of the two side plates of the ankle limit plate 103. Two arc rods 110 are fixedly connected to one end of the two side plates of the foot limit plate 104 facing the ankle limit plate 103. The two arc rods 110 are respectively inserted into the two arc grooves 109 and are fixedly connected to the inner wall of the arc groove 109 with a first spring 111. When the foot limit plate 104 deflects downward, When the foot stop plate 104 deflects upward, the first spring 111 loses pressure and recovers its deformation. At this time, the first spring 111 pushes the two arc rods 110 to move from the inside to the outside of the arc groove 109, thereby causing the foot stop plate 104 to deflect upward and drive the patient's foot to deflect synchronously.

[0040] When the motor 107 drives the winding roller 106 to rotate, the first steel cable 108 is released. At this time, the foot limit plate 104 loses its tension and restores its deformation through the first spring 111, pushing the arc rod 110 and the foot limit plate 104 to deflect upward, thereby driving the patient's foot to deflect upward; when the motor 107 drives the winding roller 106 to rotate in the opposite direction, the first steel cable 108 is wound up. At this time, the first steel cable 108 pulls the foot limit plate 104 to deflect downward, and this reciprocating process is convenient for continuous activity training of the patient's ankle joint.

[0041] The massage mechanism 200 includes two first jet assemblies 205, which are respectively fixed on the inner sides of the two side plates of the ankle limit plate 103, and the two first jet assemblies 205 correspond to the two ends of the patient's ankle joint respectively. A first cavity 201 is opened in the bottom plate of the ankle limit plate 103, and the first jet assembly 205 is connected with the first cavity 201 by setting a first hose 206. A first piston plate 203 is movably arranged in the first cavity 201, and a through hole for the first steel cable 108 to pass through is opened on the first piston plate 203. The number of through holes is two and they are symmetrical about the first piston plate 203. The two through holes are respectively opened at the two ends of the first piston plate 203, and the first steel cable 108 is fixedly inserted in the through holes, so that the first steel cable 108 and the first piston plate 203 are fixedly connected together, and when the first steel cable 108 moves, it drives the first piston plate 203 to move synchronously.

[0042] When the foot limit plate 104 deflects upward, the first steel cable 108 and the first piston plate 203 are pulled to move. At this time, the airflow in the first cavity 201 is transported to the first jet assembly 205 through the first hose 206 through the first piston plate 203, and then the airflow is sprayed at the ankle joint of the patient through the first jet assembly 205. When the foot limit plate 104 deflects downward, the first steel cable 108 pulls the first piston plate 203 to return to its original position. At this time, the air pressure in the first cavity 201 is reduced, and then the air in the ankle limit plate 103 is sucked into the first cavity 201 through the first hose 206 and the first jet assembly 205.

[0043] A massage column 207 is vertically inserted on the bottom plate of the ankle limit plate 103, and the lower end of the massage column 207 is inserted into the first cavity 201 and cooperates with the first piston plate 203. The first piston plate 203 is used to push the massage column 207 to bulge. The first piston plate 203 includes a movable plate 203a and a semi-cylinder 203b. The semi-cylinder 203b is fixedly connected to the side of the movable plate 203a facing the surface of the ankle limit plate 103. The movable plate 203a is movably arranged in the first cavity 201. The leg limit plate 102 and the ankle limit plate 103 are fixedly connected to the foot limit plate 104. After the two first steel cables 108 are inserted into the ankle limit plate 103, they are respectively The first steel cable 108 passes through the two ends of the movable plate 203a and passes through the ankle limit plate 103 and is fixedly connected with the foot limit plate 104. When the movable plate 203a is driven to move by the first steel cable 108, the semi-cylinder 203b is in conflict with the massage column 207. When the first steel cable 108 moves, it drives the movable plate 203a and the semi-cylinder 203b to move. When the semi-cylinder 203b moves, it conflicts with the massage column 207 and pushes the massage column 207 to bulge. When the semi-cylinder 203b is separated from the massage column 207, the massage column 207 is reset. The patient's ankle joint is continuously massaged by the massage column 207 in this reciprocating manner, thereby increasing the comfort of the patient during ankle joint rehabilitation training.

[0044] The massage column 207 includes a round rod 207a and a rubber head 207b, the rubber head 207b is fixedly connected to the upper end of the round rod 207a, one end of the round rod 207a passes through the ankle limit plate 103 and is inserted into the first cavity 201 of the ankle limit plate 103, a third spring 207c is sleeved on the round rod 207a, and the two ends of the third spring 207c are respectively connected to the rubber head 207b and the bottom plate of the ankle limit plate 103, when the semi-cylinder 203b moves, it contacts the massage column 207 and pushes the round rod 207a and the rubber head 207b to bulge, when the semi-cylinder 203b is separated from the massage column 207, the round rod 207a and the rubber head 207b are reset, and at the same time, the third spring 207c is used to facilitate the speed of pulling the round rod 207a and the rubber head 207b to reset, so that the patient's ankle joint is massaged by the rubber head 207b.

[0045] A toe cap is fixedly provided at one end of the foot limiting plate 104 away from the ankle limiting plate 103. When the patient puts the foot into the foot limiting plate 104, the foot is inserted into the toe cap, and then the patient's foot is protected by the toe cap; a second jet assembly 211 is fixedly provided on the inner side of the two side plates of the foot limiting plate 104, and a second cavity 210 is provided in the bottom plate of the foot limiting plate 104. The second jet assembly 211 is connected to the second cavity 210 by providing a second hose 213. A second piston plate 204 is movably provided in the second cavity 210. When the second piston plate 204 moves, the airflow in the second cavity 210 can be transported to the second jet assembly 211 through the second hose 213, and then the airflow is sprayed on the patient's foot through the second jet assembly 211, thereby reducing the discomfort of the patient during rehabilitation training.

[0046] One side of the second piston plate 204 is connected to the inner wall of the second cavity 210 by setting a second spring 208, and the other side of the second piston plate 204 is fixedly connected to a second steel cable 209, and the other end of the second steel cable 209 passes through the foot limit plate 104 and is fixedly connected to the ankle limit plate 103. When the foot limit plate 104 deflects, the second steel cable 209 pulls the second piston plate 204 to move. When the foot limit plate 104 deflects upward, the second steel cable 209 can move the second piston plate 204. At this time, the air pressure in the second cavity 210 is reduced, and at the same time, through the second The second hose 213 cooperates with the second jet assembly 211 to suck external air into the second cavity 210, and the second spring 208 is stretched and deformed as the second piston plate 204 moves; when the foot limit plate 104 deflects downward, the second piston plate 204 loses its tension and causes the second spring 208 to lose its tension. At this time, the second spring 208 shrinks and deforms and pulls the second piston plate 204 to reset, thereby spraying the airflow in the second cavity 210 onto the patient's feet through the second hose 213 and the second jet assembly 211, thereby increasing the comfort of the patient during rehabilitation training.

[0047] Furthermore, electric heating wires 202 are provided in the first cavity 201 and the second cavity 210, and the electric heating wires 202 are used to heat the air in the first cavity 201 and the second cavity 210, and then the heated gas is sprayed onto the patient's feet through the first jet assembly 205 and the second jet assembly 211, thereby reducing the discomfort of the patient's ankle joint during movement.

[0048] Furthermore, the first jet assembly 205 includes a first hollow plate 205a and a plurality of first nozzles 205b. The first hollow plate 205a is fixedly arranged on the inner sides of the two side plates of the ankle limit plate 103. The plurality of first nozzles 205b are fixedly inserted on the side of the first hollow plate 205a away from the side plate and are used to spray jets between the two side plates. The first nozzle 205b is connected to the inner space of the first hollow plate 205a. The first hollow plate 205a is connected to the first cavity 201 through the first hose 206. When the first piston plate 203 moves, the airflow in the first cavity 201 is transported to the first hollow plate 205a through the first hose 206, and then the airflow heated by the electric heating wire 202 is sprayed at the ankle joint of the patient through the plurality of first nozzles 205b, thereby heating the ankle joint of the patient.

[0049] The second jet assembly 211 includes a second hollow plate 211a and a plurality of second nozzles 211b. The second hollow plate 211a is fixedly arranged on the inner sides of the two side plates of the ankle stop plate 103. The plurality of second nozzles 211b are fixedly plugged into the side of the second hollow plate 211a away from the side plates and are used to spray jets between the two side plates. The second nozzles 211b are connected to the inner space of the second hollow plate 211a. The second hollow plate 211a is connected to the second cavity 210 through the second hose 213. When the second piston plate 204 moves, the second cavity 210 is opened. The airflow in 210 is transported to the second hollow plate 211a through the second hose 213, and then the airflow is sprayed onto the patient's feet through a plurality of second nozzles 211b. When the weather is hot, the air in the second cavity 210 is not heated. At this time, the airflow is sprayed through the second nozzles 211b to reduce the possibility of sweating of the patient's feet. When the weather is cold, the air in the second cavity 210 is heated by the electric heating wire 202. At this time, the airflow is sprayed through the second nozzles 211b to heat the patient's feet, thereby increasing the comfort of the patient during rehabilitation training.

[0050] In summary, when the foot stop plate 104 deflects upward, the first steel cable 108 and the first piston plate 203 are pulled to move, and at this time, the heated airflow in the first cavity 201 is transported to the first jet assembly 205 through the first hose 206 through the first piston plate 203, and then the airflow heated by the electric heating wire 202 is sprayed through the first jet assembly 205 to heat the ankle joint of the patient; When the first steel cable 108 moves, it drives the movable plate 203a and the semi-cylinder 203b to move. When the semi-cylinder 203b moves, it contacts the massage column 207 and pushes the massage column 207 to bulge. When the semi-cylinder 203b separates from the massage column 207, the massage column 207 returns to its original position. The massage column 207 reciprocates in this way to continuously massage the patient's ankle joint, thereby increasing the comfort of the patient during ankle joint rehabilitation training.

A second electric push rod 101c is fixedly inserted on one side of the seat leg 101 facing the leg limit plate 102, and a U-shaped plate 101d is fixedly connected to the protruding end of the second electric push rod 101c. A connecting plate 101e is hingedly provided inside the U-shaped plate 101d, and the connecting plate 101e is fixedly connected to the back of the leg limit plate 102. When the second electric push rod 101c is started, the U-shaped plate 101d can be pushed to move. At this time, the U-shaped plate 101d can be used to easily drive the connecting plate 101e and the leg limit plate 102 to move, thereby adjusting the angle of the leg limit plate 102, and then adjusting the leg limit plate 102 to a comfortable angle for the patient, so that the patient is more comfortable when performing ankle rehabilitation training.

[0052] Furthermore, the leg limit plate 102, the ankle limit plate 103 and the foot limit plate 104 are all provided with straps 112, and Velcro is provided at both ends of the straps 112. The straps 112 are detachably provided on the leg limit plate 102, the ankle limit plate 103 and the foot limit plate 104 through the Velcro. When the patient uses the device, the straps 112 can be used to fix the patient's legs and feet on the leg limit plate 102, the ankle limit plate 103 and the foot limit plate 104, thereby reducing the possibility of the patient's legs being separated from the device when performing ankle joint rehabilitation training.

[0053] Furthermore, a threaded hole 104a is provided in the pin shaft that hinges the foot limit plate 104 and the ankle limit plate 103, and a screw 104b is threadedly inserted in the threaded hole 104a. After the screw 104b passes through the threaded hole 104a, it is fixedly connected to a massage head 104c. The massage head 104c is a semicircular rubber block. A limiting rod 104d is movably inserted on the vertical plate of the ankle limit plate 103, and the limiting rod 104d passes through the vertical plate and is fixedly connected to the massage head 104c. The screw 104b is threadedly assembled in the threaded hole 104a, and the massage head 104c and the screw 104b are limited by the limiting rod 104d. When the foot limit plate 104 deflects, it drives the pin shaft to rotate. At this time, the screw 104b in the pin shaft drives the massage head 104c to move and massage the patient's ankle joint, thereby reducing the discomfort of the patient during ankle joint rehabilitation.

[0054] In summary, the straps 112 can be used to fix the patient's legs and feet on the leg limit plate 102, the ankle limit plate 103 and the foot limit plate 104, and when the second electric push rod 101c is started, it can push the U-shaped plate 101d to move. At this time, the U-shaped plate 101d can be used to drive the connecting plate 101e and the leg limit plate 102 to move, thereby adjusting the angle of the leg limit plate 102, and then adjusting the leg limit plate 102 to a comfortable angle for the patient, so that the patient can be more comfortable during ankle joint rehabilitation training.

[0055] Example 3 Reference Figure 1 , which is the third embodiment of the present invention. This embodiment is based on the previous two embodiments. Two armrests are symmetrically arranged on the top of the seat 101. A starting switch is arranged on the armrests. The starting switch is connected to the motor 107 through a wire. When the patient sits on the seat 101, the armrests increase the patient's stability during ankle joint rehabilitation training. When the device needs to be used, the motor 107 is started by pressing the starting switch.

[0056] In summary, the above three embodiments can be combined, and the overall action process after the combination is: first, the patient sits on the seat 101, and puts the legs into the leg limiting plate 102, the ankle limiting plate 103 and the leg limiting plate 102, at this time, the patient's legs are limited by the leg limiting plate 102, the ankle limiting plate 103 and the leg limiting plate 102, so as to reduce the possibility that the leg shaking during the patient's ankle joint rehabilitation training affects the rehabilitation training effect; Then, the second electric push rod 101c is started to push the U-shaped plate 101d to move. At this time, the U-shaped plate 101d facilitates the connection plate 101e and the leg limit plate 102 to move, thereby adjusting the angle of the leg limit plate 102, and then adjusting the leg limit plate 102 to a comfortable angle for the patient; When the patient presses the start switch, the motor 107 is started. When the motor 107 drives the winding roller 106 to rotate, the first steel cable 108 is released. At this time, the foot limit plate 104 loses its tension and restores its deformation through the first spring 111, pushing the arc rod 110 and the foot limit plate 104 to deflect upward, thereby driving the patient's foot to deflect upward. When the foot limit plate 104 deflects upward, it pulls the first steel cable 108 and the first piston plate 203 to move. At this time, the first piston plate 203 transports the heated airflow in the first cavity 201 to the first hollow plate 205a through the first hose 206, and then the airflow is sprayed on the patient's ankle joint through a plurality of first nozzles 205b, thereby heating the patient's ankle joint; When the foot stop plate 104 deflects upward, the second steel cable 209 enables the second piston plate 204 to move, and the air pressure in the second cavity 210 is reduced. At the same time, the second hose 213 cooperates with the second jet assembly 211 to suck the external air into the second cavity 210, and the second spring 208 is stretched and deformed as the second piston plate 204 moves; When the motor 107 drives the winding roller 106 to rotate in the opposite direction, the first steel cable 108 is wound up. At this time, the first steel cable 108 pulls the foot limit plate 104 to deflect downward. This reciprocating process is convenient for continuously exercising the patient's ankle joint. When the foot limit plate 104 deflects downward, the first steel cable 108 pulls the first piston plate 203 to reset. At this time, the air pressure in the first cavity 201 is reduced, and then the air in the ankle limit plate 103 is sucked into the first cavity 201 through the first hose 206 and the first jet assembly 205 for heating, so as to subsequently heat the patient's ankle joint; When the foot stop plate 104 deflects downward, the second piston plate 204 loses its tension and causes the second spring 208 to lose its tension. At this time, the second spring 208 contracts and deforms and pulls the second piston plate 204 to reset, so that the airflow in the second cavity 210 is transported to the second hollow plate 211a through the second hose 213, and then the airflow is sprayed on the patient's feet through a plurality of second nozzles 211b. When the weather is hot, the air in the second cavity 210 is not heated. At this time, the second nozzle 211b sprays the airflow to reduce the possibility of sweating of the patient's feet. When the weather is cold, the air in the second cavity 210 is heated. At this time, the second nozzle 211b sprays the airflow to heat the patient's feet, thereby increasing the comfort of the patient during rehabilitation training; When the first steel cable 108 moves, it drives the movable plate 203a and the semi-cylinder 203b to move. When the semi-cylinder 203b moves, it contacts the massage column 207 and pushes the round rod 207a and the rubber head 207b to bulge. When the semi-cylinder 203b separates from the massage column 207, the round rod 207a and the rubber head 207b are reset. At the same time, the third spring 207c is used to increase the speed of pulling the round rod 207a and the rubber head 207b to reset, so that the patient's ankle joint is massaged by the rubber head 207b.
