[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0041] Furthermore, the terms “first”, “second”, etc. are merely used for distinguishing descriptions and should not be understood as indicating or implying relative importance.

[0042] Please refer to Figure 1-Figure 3 As shown, an embodiment of the present invention provides an ankle joint trainer 10, which is used for rehabilitation training of the ankle joint. During the rehabilitation training, the ankle joint trainer 10 can meet the training requirements of plantar flexion or dorsiflexion, inversion or eversion of the ankle joint.

[0043] The specific structure of the ankle joint trainer 10 is as follows: the ankle joint trainer 10 is mainly composed of a base 11 , a driving component 13 and a training component 15 . The driving component 13 is arranged on the base 11 , and the training component 15 is arranged on the driving component 13 .

[0044] Specifically, the structure of the base 11 is not limited. The base 11 mainly plays a supporting role. In this embodiment, the base 11 can adopt but is not limited to the following solutions: Figure 4As shown, the base 11 includes a base body 110 and a mounting portion 111, the base body 110 is used for contacting with the ground for support, and the mounting portion 111 is arranged above the base body 110. Among them, the base body 110 can be in an I-shape, and the base 11 includes two horizontal frames and a vertical frame, the two horizontal frames are arranged in parallel and spaced apart, the vertical frame is located between the two horizontal frames, and the two ends of the vertical frame are respectively connected to the two horizontal frames, and the connection method is not limited, such as one-piece molding, welding, detachable connection, etc. The vertical frame and the horizontal frame are arranged at an angle, and the two can be perpendicular to each other. The horizontal frame can adopt a tubular structure or a rod-shaped structure, etc. In this embodiment, the horizontal frame adopts a circular tube structure, and the vertical frame can also adopt a tubular structure or a rod-shaped structure, etc. A plurality of foot supports 112 may be provided at the bottom of the seat body 110. The number of foot supports 112 is unlimited. The height of foot supports 112 can be adjusted. The structure and style of foot supports 112 can refer to the prior art. For example, foot supports 112 include a connection portion 131 and a screwing portion. The connection portion 131 is connected to the seat body 110. The connection method is unlimited, such as integral molding, bolt connection, etc. The screwing portion is provided at the lower end of the connection portion 131. The screwing portion and the connection portion 131 are connected by a thread. When the screwing portion is rotated, the position of the screwing portion on the connection portion 131 can be adjusted, that is, the screwing portion can be raised and lowered along the connection portion 131 to change the distance between the bottom of the screwing portion and the ground. In this embodiment, foot supports 112 may be provided at the bottom of both ends of each horizontal frame. The foot supports 112 enable the seat body 110 to adapt to uneven ground and keep the base 11 in a horizontal state. The mounting portion 111 is disposed on the base 110. Specifically, the mounting portion 111 is located above the vertical frame. The structure of the mounting portion 111 is not limited. Such a configuration can make the base 110 more secure. In other embodiments, the base 110 can also adopt a plate structure, a frame structure, etc.

[0045] The driving assembly 13 is arranged on the base 11. Specifically, the driving assembly 13 can be installed above the middle of the seat body 110. Such an arrangement can enhance stability. In the present embodiment, the driving assembly 13 is rotatably arranged on the mounting portion 111. The driving assembly 13 is tilted relative to the rotation center line of the mounting portion 111. The tilted arrangement mentioned here means that after the seat body 110 is placed horizontally on the ground, the driving assembly 13 is tilted relative to the vertical direction relative to the rotation center line of the mounting portion 111. The tilt angle can be 30°-60°. In other embodiments, the driving assembly 13 can also be arranged vertically relative to the rotation center line of the mounting portion 111. In other embodiments, the driving assembly 13 can also be located at the upper edge of the seat body 110, etc., and the driving assembly 13 and the seat body 110 can also be fixedly connected, that is, the driving assembly 13 cannot rotate relative to the seat body 110.

[0046] The rotational connection method between the driving assembly 13 and the mounting portion 111 can refer to the rotational connection method in the prior art. In this embodiment, the following solutions can be adopted but are not limited to: Figure 5 , Figure 6 As shown, the driving component 13 is T-shaped or inverted L-shaped, and the driving component 13 includes an inclined portion and a connecting portion 131. The inclined portion can adopt a rotating column 130, and the connecting portion 131 is located at the top of the rotating column 130. The mounting portion 111 includes a rotating seat 113, a limit member 114 and a knob plunger 115. The rotating seat 113 is provided with a mounting groove 116, and the mounting groove 116 can be a blind hole with a circular cross-section. The rotating column 130 is inclined and rotatably inserted in the mounting groove 116, and a clearance fit can be adopted between the rotating column 130 and the mounting groove 116. In order to enable the driving assembly 13 to work stably in different positions, it is necessary to add a limiting structure. Specifically, a limiting slide groove 133 and two positioning grooves 134 are provided on the rotating column 130. The limiting slide groove 133 is arranged along the circumference of the rotating column 130, and the central angle of the limiting groove can be controlled at 80°-100°. In this embodiment, the central angle of the limiting groove can be 90°, and the positioning groove 134 can be a blind hole or a groove. The limiting member 114 and the knob plunger 115 are arranged along the radial direction of the rotating seat 113. The limiting member 114 and the knob plunger 115 pass through the side wall of the rotating seat 113 and extend into the mounting groove 116. The limiting member 114 is inserted into the limiting slide groove 133. When the rotating column 130 rotates in the mounting groove 116, the limiting member 114 and the limiting slide groove 133 can slide relative to each other. The limiting slide groove 133 can limit the rotation angle of the rotating column 130 to prevent its rotation angle from being too large. The knob plunger 115 is selectively inserted into one of the positioning grooves 134, that is, when the rotating column 130 rotates in the installation groove 116, the rotating column 130 has two stop points. When the rotating column 130 is located at any stop point, the knob plunger 115 can be inserted into the corresponding positioning groove 134 to lock the rotating column 130.

[0047] The connection mode between the knob plunger 115 and the rotating seat 113, and the connection mode between the stopper 114 and the rotating seat 113 are not limited. For example, the knob plunger 115 and the rotating seat 113 are connected by threaded connection, and the knob plunger 115 can be inserted into the positioning groove 134 or disengaged from the positioning groove 134 by screwing the knob plunger 115; or the knob plunger 115 is slidably connected to the rotating seat 113 along its own axial direction, and the knob plunger 115 is reset by a reset spring, so that the knob plunger 115 is inserted into the positioning groove 134, and when the knob plunger 115 is pulled outward, the knob plunger 115 can be pulled outward and disengaged from the positioning groove 134. The limiting member 114 is made of a countersunk screw or the like, and a stepped hole is provided on the rotating seat 113 . The limiting member 114 is located in the stepped hole and is threadedly connected to a portion of the stepped hole with a smaller diameter. The end of the limiting member 114 extends into the limiting slot 133 .

[0048] In addition, in order to prevent the drive assembly 13 from rotating out of position or rotating at an excessive angle, causing the drive assembly 13 to work in a non-standard position and affecting the rehabilitation training effect, the present embodiment further provides the following solution: the mounting portion 111 further includes two micro magnets 117, which are small magnets. The size of the micro magnets 117 can be set as needed. The micro magnets 117 are arranged in the mounting groove 116. The position of the micro magnets 117 in the mounting groove 116 is not limited. For example, the micro magnets 117 are located on the bottom surface or side surface of the mounting groove 116. In the present embodiment, the bottom surface of the mounting groove 116 is provided with two mounting grooves, and the micro magnets 117 are embedded in the mounting grooves of the mounting groove 116. The rotating column 130 is provided with a magnetic induction proximity switch 135 matching the micro magnet 117. The magnetic induction proximity switch 135 can rotate with the rotating column 130. The magnetic induction proximity switch 135 is exposed from the bottom surface of the rotating column 130, and the magnetic induction proximity switch 135 matches the position of the micro magnet 117. When the knob plunger 115 is plugged into and matched with any one of the positioning slots 134, the magnetic induction proximity switch 135 is opposite to the corresponding micro magnet 117. When the magnetic induction proximity switch 135 is opposite to the micro magnet 117, the magnetic induction proximity switch 135 can detect the micro magnet 117 and enable the control system to control the drive component 13 to switch the working state. The working state of the drive component 13 is divided into plantar flexion or dorsiflexion state and inversion or eversion state. In different states, the swing amplitude, swing frequency, etc. of the drive component 13 may be different.

[0049] The connecting portion 131 may be a shell structure, and one end of the connecting portion 131 is closed. Figure 7-Figure 9 As shown, the driving assembly 13 further includes an action part 132, which is disposed in the connecting part 131. The action part 132 includes an action motor, and the action motor has an output shaft, which is exposed from one end of the connecting part 131. The training assembly 15 is disposed on the driving assembly 13, and the driving assembly 13 can drive the training assembly 15 to work. Specifically, the training assembly 15 includes a connecting member 150, a shoe 151 and a calf fixing member 152.

[0050] The connecting member 150 is connected to the output shaft of the action part 132, and the connection method can be connected through a hand-tightening bolt 158. The action part 132 can drive the connecting member 150 to swing. The shape of the connecting member 150 is not limited. In this embodiment, the connecting member 150 is an L-shaped structure. The vertical part of the connecting member 150 is connected to the action part 132, and the horizontal part of the connecting member 150 can be detachably connected to the bottom of the shoe 151. For example, the connecting member 150 and the bottom of the shoe 151 can be fixed by a plunger or a hand-tightening bolt 158.

[0051] The structure of the shoe 151 can refer to the prior art. The shoe 151 is arranged on the connecting member 150 and can change its direction. In this embodiment, please refer to Fig.10 , Fig.11 As shown, one side of the bottom of the shoe 151 and the bottom of the heel are both provided with a connection portion 131, and the lateral portion of the connection member 150 is embedded in the connection portion 131 and fixed by a hand-tightening bolt 158. When the connection member 150 is connected to different connection portions 131, it can adapt to different modes. In addition, the same connection member 150 can be used to adapt to different modes, and connection members 150 of different sizes can also be used to adapt to different modes. In addition, in other embodiments, the connection member 150 and the shoe 151 can also be fixed in other ways.

[0052] During the rotation of the driving assembly 13, the connecting member 150 can be driven to be located at one side or in front of the mounting portion 111. During the rotation of the driving assembly 13, the ankle joint trainer 10 has a first state and a second state. When the ankle joint trainer 10 is in the first state, the shoe 151 is located at one side of the mounting portion 111 and extends in the front-to-back direction, and the calf fixing member 152 is located above the shoe 151. At this time, the ankle joint trainer 10 is in plantar flexion or dorsiflexion mode, and plantar flexion or dorsiflexion training can be performed. When the ankle joint trainer 10 is in the second state, the shoe 151 is located obliquely above the mounting portion 111, the shoe 151 extends in the front-to-back direction and is tilted upward, and the calf binding is located obliquely above the rear end of the shoe 151. At this time, the ankle joint trainer 10 is in inversion or eversion mode, and inversion or eversion training can be performed. This arrangement allows the patient to perform different training modes in the same position without moving the position, and it is more compatible with the patient's training position.

[0053] The calf fixing member 152 is used to fix the calf. The calf fixing member 152 is fixed to the driving assembly 13. The action part 132 cannot drive the calf fixing member 152 to rotate. The top of the calf fixing member 152 is provided with a calf binding for fixing the calf. The calf binding is located above or obliquely above the shoe 151. If there is no calf fixing member 152, during the ankle joint training, since the calf can move and the swing angle of the connecting member 150 remains unchanged, the swing amplitude of the ankle joint cannot be accurately controlled and feedbacked. After the calf fixing member 152 is added, the calf is completely fixed, and the foot is also fixed by the shoe 151. The swing amplitude of the connecting member 150 can be accurately controlled, and the swing amplitude of the ankle joint can achieve accurate control and feedback.

[0054] The action part 132 has a rotating part, which is coaxially arranged with the output shaft and is transmission-connected, and the rotating part is provided with an anti-mistake groove 136, and a circular arc-shaped limiting groove 153 is provided on one side of the calf fixing part 152, and a circular arc-shaped anti-mistake protrusion 154 and a limiting protrusion 155 are provided on one side of the connecting member 150, and the anti-mistake protrusion 154 is embedded in the anti-mistake groove 136, and the limiting protrusion 155 is slidably embedded in the limiting groove 153. Such a configuration makes the installation of the connecting member 150 more convenient and accurate.

[0055] The function of the calf binding is to fix the calf, so that the patient's calf remains motionless during the training process, and only the foot is moved, which can accurately control the angle of motion of the ankle joint and better train the ankle. The structure of the calf binding can adopt but is not limited to the following scheme: the calf binding includes a calf support plate 156 and a calf pad 157, the calf support plate 156 is arranged at the top of the calf fixing member 152, the calf support plate 156 and the calf fixing member 152 can be connected by an integrated molding, a detachable connection, etc., the calf pad 157 is located on the inner side of the support plate, and the calf pad 157 can be made of a flexible material so that the calf binding can be in flexible contact with the patient's calf. The cross-sections of the calf support plate 156 and the calf pad 157 are both C-shaped, and the openings of the calf support plate 156 and the calf pad 157 are matched with the direction of the shoe 151. In this way, the patient's calf can be inserted into the calf binding through the openings of the calf support plate 156 and the calf pad 157, and the wearing method is simple.

[0056] In addition, the ankle joint trainer 10 also includes a control system, which is used to detect the state of the ankle joint trainer 10 and control the action of the action part 132. The magnetic induction proximity switch 135 and the micro magnet 117 can be considered as part of the control system. In addition, the control system can also include structures such as control circuits.

[0057] The working method of the ankle joint trainer 10 provided in this embodiment is as follows:

[0058] Place the ankle joint trainer 10 on the ground, adjust the height of the foot supports 112, make different foot supports 112 contact the ground respectively, and make the base 11 in a horizontal state;

[0059] Select a training mode, for example, select flexion / dorsiflexion training. If the initial state of the ankle joint trainer 10 matches the training mode, there is no need to adjust the direction of the drive assembly 13; if the initial state of the ankle joint trainer 10 does not match the training mode, it is necessary to adjust the direction of the drive assembly 13, that is, the knob plunger 115 is disengaged from the mounting slot 116, and the drive assembly 13 is rotated until the knob plunger 115 is opposite to another mounting slot 116, at which time, the knob plunger 115 is inserted into the mounting slot 116;

[0060] The control system detects the mode of the ankle joint trainer 10 and makes the rotation speed, rotation angle and other actions of the action part 132 match the mode;

[0061] Fix the shoe 151 and the connecting member 150 by means of hand-tightening bolts 158;

[0062] Provide patients with appropriate rehabilitation training.

[0063] When you need to change the training mode, just repeat some of the above steps. The above steps can be added, modified, and adjusted in order as needed.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
