[0028] See also Figure 3 and Figure 4 In one embodiment, the tracking training structure also includes a driving component. The arc guide frame 30 can be slidably set on the base 10 along the length direction of the base 10. The driving component is set on the base 10 and connected to the arc guide frame 30, and is used to drive the arc guide frame 30 to slide. A second shifting groove 3062 is opened on the shifting rod 306, and the mounting column 301 is slidably set in the second shifting groove 3062.

[0029] In the above embodiment, the driving component drives the arc guide frame 30 to slide along the length direction of the base 10, so that the arc guide frame 30 can drive the tracking box 302 to move closer to or away from the seat 102 through the mounting column 301, thereby facilitating the adjustment of the distance between the tracking box 302 and the seat 102 according to the patient's vision, ensuring that the patient can clearly see the tracking box 302, facilitating use by different patients, and improving the practicality of the device.

[0030] On the basis of the above embodiment, further, the driving assembly includes a first screw 40 and a motor 401; a first guide groove 104 is opened at the top of the base 10, and a first guide block 307 is provided at the bottom end of the arc-shaped guide frame 30.

The motor 401 is set on the base 10, and the output end is coaxially connected to the first screw 40.

[0031] The first screw 40 is driven to rotate by the motor 401, and the rotation of the first screw 40 and the threaded cooperation of the first guide block 307 can drive the first guide block 307 to drive the arc guide frame 30 to move. Conversely, the first screw 40 is driven to rotate in the opposite direction by the motor 401, and the reverse rotation of the first screw 40 and the threaded cooperation of the first guide block 307 can drive the first guide block 307 to drive the arc guide frame 30 to move in the opposite direction. It is convenient to drive the arc guide frame 30 to move along the length direction of the base 10, and stop the motor 401 to stop the first screw 40 from rotating. At this time, the first screw 40 and the first guide block 307 are threadedly cooperated to fix the first guide block 307, thereby fixing the arc guide frame 30. The arc guide frame 30 can be fixed without additional operation, and the arc guide frame 30 is convenient to fix after movement.

[0032] See also Figure 1 and Figures 4 to 6 In one embodiment, the leg training component also includes a lifting component, which includes a fixed plate 50, a first electric telescopic rod 501 and a telescopic column 502; the fixed plate 50 is set on the mounting plate 103 through two groups of first electric telescopic rods 501, so that the fixed plate 50 can be lifted and lowered in the vertical direction, the rotating shaft 20 is rotatably set on the fixed plate 50, and the telescopic column 502 is vertically rotatably set on the fixed plate 50, and a bevel gear 304 is set on the top of the telescopic column 502 and the rotating shaft 20, and the bottom end of the telescopic column 502 can be slidably set on the first transmission shaft 303 in the vertical direction, and the two groups of pedals 202 are coaxially provided with a holding rod 203 at the diverging ends.

[0033] Specifically in the above embodiment, a fourth guide slot 5021 is defined around the telescopic column 502, a fourth guide block 3031 is disposed on the first transmission shaft 303, and the bottom end of the telescopic column 502 is vertically inserted into the first transmission shaft 303, with the fourth guide block 3031 slidingly disposed within the fourth guide slot 5021. The cooperation between the fourth guide slot 5021 and the fourth guide block 3031 prevents the telescopic column 502 from rotating relative to the first transmission shaft 303 when the telescopic column 502 slides vertically, thereby facilitating synchronous rotation of the first transmission shaft 303 with the telescopic column 502.

[0034] In the above embodiment, the fixed plate 50 can be driven to move up and down by controlling the extension and retraction of the two groups of first electric telescopic rods 501. The upward and downward movement of the fixed plate 50 can drive the rotating shaft 20 to move up and down and the telescopic column 502 to extend and retract. The upward and downward movement of the rotating shaft 20 can adjust the height of the two groups of pedals 201, so that different patients can place their feet on the two groups of pedals 201, which is convenient for different patients to use and improves the practicality of the device. When the rotating shaft 20 rises so that the patient can hold the two groups of holding rods 203 with both hands, the rotating shaft 20 can be driven to rotate by the patient's hands alternately pushing and pulling the holding rods 203, thereby facilitating the reciprocating movement of the tracking box 302 for tracking exercise through hand movement. While exercising the upper limbs, the tracking box 302 is driven to move back and forth for tracking exercise, thereby improving the practicality of the device.

[0035] See also Figure 4 and Figure 6 In one embodiment, the tracking training structure further includes an adjustment component, and the dial shaft 3051 is set at the bottom end of the turntable 305 through the adjustment component. Driving the adjustment component can drive the dial shaft 3051 to move radially along the turntable 305.

[0036] In the above embodiment, the eccentricity of the dial shaft 3051 can be adjusted by driving the dial shaft 3051 to move radially along the turntable 305 by the adjustment component. It can be understood that when the eccentricity of the dial shaft 3051 increases, the turntable 305 rotates through the dial shaft 3051 and the first dial groove 3061 to drive the dial rod 306 to swing back and forth at an angle that increases, and the dial rod 306 drives the mounting column 301 and the tracking box 302 to move back and forth to increase. Conversely, when the eccentricity of the dial shaft 3051 decreases, the turntable 305 rotates through the dial shaft 3051 and the first dial groove 3061 to drive the dial rod 306 to swing back and forth at an angle that decreases, and the dial rod 306 drives the mounting column 301 and the tracking box 302 to move back and forth to decrease. This makes it easy to adjust the reciprocating stroke of the tracking box 302 according to the patient's tracking training needs, avoid injuries caused by excessive head turning of the patient, and improve the safety of the device.

[0038] By rotating the second screw 601 and engaging the second guide block 60 with the thread, the second guide block 60 can be driven to drive the dial shaft 3051 to slide radially along the turntable 305, and the eccentricity of the dial shaft 3051 can be easily adjusted. When the second screw 601 is stopped, the second screw 601 and the second guide block 60 are engaged with the thread to fix the second guide block 60, thereby fixing the dial shaft 3051, and conveniently fixing the eccentricity of the dial shaft 3051.

The transmission gear 703 rotates through the second transmission shaft 702 to drive one group of rotating rollers 70 and one group of synchronous pulleys 705 to rotate. The synchronous pulley 705 rotates through the synchronous belt 706 to drive another group of synchronous pulleys 705 to rotate, thereby driving the two groups of rotating rollers 70 to rotate synchronously, which is convenient for driving the two groups of rotating rollers 70 to rotate synchronously.

[0044] The specific implementation of the above-mentioned cognitive rehabilitation training device for post-stroke dementia is as follows: The patient sits on the chair 102, places both feet on the pedals 201, and looks at the tracking box 302. Then, the patient's legs alternately step on the pedals 201 to rotate the rotating shaft 20.

The up and down movement of the rotating shaft 20 can adjust the height of the two sets of pedals 201, so that different patients can place their feet on the two sets of pedals 201, which is convenient for different patients to use and improves the practicality of the device. When the rotating shaft 20 rises so that the patient can hold the two sets of holding rods 203 with both hands, the rotating shaft 20 can be driven to rotate by the patient's hands alternately pushing and pulling the holding rods 203, so as to facilitate the reciprocating movement of the tracking box 302 for tracking exercise through hand movement. The tracking box 302 can be driven to move back and forth for tracking exercise while exercising the upper limbs, thereby improving the practicality of the device.

[0048] By rotating the second screw 601 and the second guide block 60, the second guide block 60 can be driven to drive the dial shaft 3051 to slide radially along the turntable 305, thereby adjusting the eccentricity of the dial shaft 3051. It can be understood that when the eccentricity of the dial shaft 3051 increases, the turntable 305 rotates through the dial shaft 3051 and the first dial groove 3061 to drive the dial rod 306 to swing back and forth, and the stroke of the mounting column 301 and the tracking box 302 to move back and forth by the dial rod 306 increases. Conversely, when the eccentricity of the dial shaft 3051 decreases, the turntable 305 rotates through the dial shaft 3051 and the first dial groove 3061 to drive the dial rod 306 to swing back and forth, and the stroke of the mounting column 301 and the tracking box 302 to move back and forth by the dial rod 306 is reduced, thereby facilitating the adjustment of the reciprocating stroke of the tracking box 302 according to the patient's tracking training needs, avoiding damage caused by excessive head turning of the patient, and improving the safety of the device.
