Description

Technical Field

[0001] This invention belongs to the field of rehabilitation assistive technology, specifically, it relates to a hand-eye coordination rehabilitation assistive system and method. Background Technology

[0002] Hand-eye coordination is a core component of human motor function, and its recovery is crucial for the rehabilitation process of patients with stroke sequelae, neurological injuries, and limb dysfunction. Clinical practice shows that scientific hand-eye coordination rehabilitation training can significantly improve patients' limb control, visual tracking ability, and the efficiency of brain neural pathway reconstruction, helping patients gradually regain their ability to perform daily activities independently.

[0003] However, existing hand-eye coordination rehabilitation exercises often involve patients holding two balls in their daily lives, throwing them with their left and right hands, and then catching them again. However, throwing the balls for a long time can be tiring for patients. Also, if the patient fails to catch the ball, it will fall to the ground, requiring them to pick it up before continuing the exercise, which is quite inconvenient.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a hand-eye coordination rehabilitation assistive system.

[0006] The basic concept of the technical solution adopted in this invention is: A hand-eye coordination rehabilitation assistive system includes a mounting housing and a flip plate hinged to the side wall of the mounting housing. A placement housing is located on the side of the flip plate near the mounting housing, and mounting slots are formed through the opposite side walls of the placement housing. The placement housing has a left arc-shaped channel and a right arc-shaped channel, which are symmetrical to each other. Sliding balls are respectively installed in the inner cavities of the left and right arc-shaped channels. Sliding slots are formed through the side walls of both the left and right arc-shaped channels, and a left connecting rod and a right connecting rod are respectively movably inserted through the inner cavities of the sliding slots. Sliding balls are respectively attached above the left and right connecting rods. A fixed housing is located on one side wall of the placement housing, and a cam is installed in the inner cavity of the fixed housing.

[0007] In a preferred embodiment of the present invention, a mounting plate is provided on the side wall of the flip plate near the mounting housing, and a rectangular slot is provided on the side wall of the mounting plate away from the flip plate. A partition is provided inside the rectangular slot, and a housing is placed inside the rectangular slot.

[0008] In a preferred embodiment of the present invention, a slot is provided at the bottom of the inner cavity of the housing, and a hydraulic cylinder is provided in the inner cavity of the slot. An L-shaped mounting plate is provided at the output end of the hydraulic cylinder, an electric push rod is provided on one side wall of the L-shaped mounting plate, and an L-shaped plug rod is provided at the output end of the electric push rod.

[0009] In a preferred embodiment of the present invention, a rectangular mounting cylinder and a plug-in block are respectively provided at opposite ends of the right connecting rod and the left connecting rod. The rectangular mounting cylinder and the plug-in block fit together. A horizontal return spring is provided in the inner cavity of the rectangular mounting cylinder. A fixing plate is provided at the bottom of the rectangular mounting cylinder. A positioning slot is provided on the fixing plate, and the positioning slot fits together with the L-shaped plug-in rod.

[0010] In a preferred embodiment of the present invention, the two opposite side walls of the rectangular slot are provided with movable sliding grooves, the two movable sliding grooves are symmetrical to each other, and movable sliders are slidably arranged in the inner cavity of the two movable sliding grooves. The two movable sliders are symmetrical to each other, and the opposite ends of the two movable sliders are respectively connected to a right connecting rod and a left connecting rod.

[0011] In a preferred embodiment of the present invention, each of the movable sliders is provided with a vertical return spring at its bottom, and the other end of the vertical return spring is provided on the inner wall of the movable groove.

[0012] In a preferred embodiment of the present invention, the inner cavity of the movable slide is further provided with a placement slot, the placement slot movably penetrates the mounting plate, and the inner cavity of the placement slot is provided with a connecting rod, one end of the connecting rod is provided on the movable slider, and the end of the connecting rod away from the movable slider is provided with a drive plate.

[0013] In a preferred embodiment of the present invention, a threaded rod is engaged and penetrated on the fixed housing, a knob is provided at the end of the threaded rod away from the fixed housing, the end of the threaded rod away from the knob is rotatably disposed in the inner cavity of the fixed housing, a cam is provided on the threaded rod, and one end of the cam is attached to the side wall of the drive plate.

[0014] A hand-eye coordination rehabilitation aid method, the steps are as follows: Step 1: Flip the flip plate until it is perpendicular to the mounting housing, so that the housing unfolds synchronously with the mounting plate. Confirm that the sliding balls in the left and right arc channels are securely placed, and check that the control components and the connections of each part are normal. Step 2: Start the hydraulic cylinder through the control component of the housing, which drives the L-shaped mounting plate, electric push rod and L-shaped plug rod to move down. The L-shaped plug rod is inserted into the positioning slot of the fixed plate, and at the same time, it pulls the rectangular mounting cylinder, plug block and connecting rod down, squeezing the vertical return spring. Step 3: Control the electric push rod to drive the L-shaped plug rod to separate from the fixed plate. The vertical return spring rebounds and drives the moving slider and connecting rod to move upward, pushing the sliding ball into the rectangular slot. The patient stares at the sliding ball and presses it manually to complete the hand-eye coordination exercise. Step 4: When exercising with one hand, turn the knob to move the threaded rod and cam away from the drive plate. The horizontal return spring pops out the plug block, separating it from the rectangular mounting cylinder. Only the sliding ball on one side slides out, which is suitable for one-handed exercise. Step 5: After exercise, reset the hydraulic cylinder and electric push rod by controlling the components to return the sliding ball to the arc-shaped channel, flip the flip plate to fit the mounting shell, and complete the storage for easy carrying.

[0015] Compared with the prior art, the present invention has the following advantages: This invention achieves stable operation of coordinated hand exercises by symmetrically arranging the left and right arc-shaped channels of the housing, combined with sliding balls and left and right connecting rods in the sliding groove, and with the structural design of the mounting groove. At the same time, the cam inside the housing is linked with the threaded rod, drive plate and horizontal return spring, which can flexibly switch between single-hand and double-hand exercise modes to adapt to the needs of different rehabilitation stages, while ensuring that the sliding balls do not fall off.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0020] like Figures 1 to 7 As shown, a hand-eye coordination rehabilitation assistive system includes a mounting housing 1 and a flip plate 11 hinged to the side wall of the mounting housing 1. A placement housing 2 is provided on the side of the flip plate 11 near the mounting housing 1, and mounting slots 213 are provided through the opposite side walls of the placement housing 2. The inner cavity of the placement housing 2 is provided with a left arc-shaped channel 21 and a right arc-shaped channel 211, which are symmetrical to each other. Sliding balls 212 are respectively provided in the inner cavity of the left arc-shaped channel 21 and the right arc-shaped channel 211. Sliding slots 214 are provided through the side walls of the left arc-shaped channel 21 and the right arc-shaped channel 211, and a left connecting rod 241 and a right connecting rod 232 are respectively movably passed through the inner cavity of the sliding slots 214. Sliding balls 212 are respectively attached above the left connecting rod 241 and the right connecting rod 232. A fixed housing 3 is provided on one side wall of the placement housing 2, and a cam 322 is provided in the inner cavity of the fixed housing 3. By symmetrically setting the left arc-shaped channel 21 and right arc-shaped channel 211 of the housing 2, and with the sliding ball 212 and the left connecting rod 241 and right connecting rod 232 in the sliding groove 214, and with the structural design of the mounting groove 213, stable operation of hand-to-hand coordination exercise can be achieved. At the same time, the cam 322 in the fixed housing 3 is linked with the threaded rod 321, the drive plate 311 and the horizontal return spring 233, which can flexibly switch between single-hand and double-hand exercise modes to adapt to the needs of different rehabilitation stages.

[0021] In a specific embodiment, a mounting plate 12 is provided on the side wall of the flip plate 11 near the mounting housing 1. A rectangular slot 121 is formed on the side wall of the mounting plate 12 away from the flip plate 11. A partition 122 is provided inside the rectangular slot 121, and the housing 2 is placed inside the rectangular slot 121. In this configuration, the mounting plate 12 provides a stable bearing base for the placement housing 2 and the subsequent movement of the sliding ball 212. The rectangular slot 121 is adapted to the movement trajectory of the sliding ball 212. The partition 122 divides the rectangular slot 121 into two independent areas, avoiding interference between the sliding balls 212 that pop out of the left and right arc-shaped channels 211. At the same time, it ensures the accurate positioning of the housing 2 and provides a regular space for the movement of the ball and hand pressing during hand-eye coordination exercises.

[0022] Furthermore, a slot is provided at the bottom of the inner cavity of the housing 2, and a hydraulic cylinder 22 is installed inside the slot. An L-shaped mounting plate 221 is provided at the output end of the hydraulic cylinder 22, and an electric push rod 222 is provided on one side wall of the L-shaped mounting plate 221. An L-shaped plug-in rod 223 is provided at the output end of the electric push rod 222. In this configuration, the hydraulic cylinder 22 serves as a vertical power source. The L-shaped mounting plate 221 enables the stable installation and synchronous lifting of the electric push rod 222. The L-shaped plug-in rod 223 fits into the positioning slot of the fixed plate 23, forming a connecting structure for power transmission. This provides controllable power for subsequently driving the left and right connecting rods to lift and compress the vertical return spring 252. At the same time, the L-shaped structure design improves the stability of the component connection and avoids deviation during power transmission.

[0023] Furthermore, a rectangular mounting cylinder 231 and a plug-in block 24 are respectively provided at opposite ends of the right connecting rod 232 and the left connecting rod 241. The rectangular mounting cylinder 231 and the plug-in block 24 fit together. A horizontal return spring 233 is provided inside the rectangular mounting cylinder 231. A fixing plate 23 is provided at the bottom of the rectangular mounting cylinder 231. A positioning slot is opened on the fixing plate 23, and the positioning slot fits together with the L-shaped plug-in rod 223. In this configuration, the fit between the rectangular mounting cylinder 231 and the plug-in block 24 enables the detachable linkage between the right connecting rod 232 and the left connecting rod 241. The horizontal return spring 23 provides the reset power for the separation of the two. The fixing plate 23, through the cooperation of the positioning slot and the L-shaped plug-in rod 223, becomes a key component for receiving the power of the hydraulic cylinder 22 and transmitting it to the connecting rod. This not only ensures the synchronous movement of the left and right connecting rods when exercising with both hands, but also lays the foundation for the structural separation when exercising with one hand, thus improving the functional adaptability of the equipment.

[0024] Furthermore, the two opposite side walls of the rectangular slot 121 are provided with movable grooves 25. The two movable grooves 25 are symmetrical to each other, and movable sliders 251 are slidably arranged inside the cavity of each movable groove 25. The two movable sliders 251 are symmetrical to each other, and the opposite ends of the two movable sliders 251 are respectively connected to the right connecting rod 232 and the left connecting rod 241. In this configuration, the movable grooves 25 and the movable sliders 251 constitute a sliding guide mechanism. The symmetrical design ensures that the movement trajectories of the right connecting rod 232 and the left connecting rod 241 are consistent, avoiding tilting or jamming. Through the sliding cooperation between the sliders and the grooves, the movement of the connecting rods is restricted to the vertical direction, providing precise guidance for the stable ejection of the sliding ball 212 and ensuring the predictability of the ball movement during rehabilitation exercises.

[0025] Furthermore, each movable slider 251 is equipped with a vertical return spring 252 at its bottom, and the other end of the vertical return spring 252 is disposed on the inner wall of the movable slide groove 25. In this configuration, the vertical return spring 252 serves as an elastic return component. When the connecting rod drives the slider to move downward, it is compressed and stores elastic potential energy. When the L-shaped plug rod 223 separates from the fixed plate 23, the elastic potential energy is released and drives the movable slider 251 to return upward, thereby causing the connecting rod and the sliding ball 212 to pop out. Its elastic force can adapt to the exercise needs of patients at different rehabilitation stages. At the same time, the buffering effect of the spring can avoid rigid collisions between components and extend the service life of the equipment.

[0026] Furthermore, the inner cavity of the movable slide 25 is also provided with a placement slot 123, which movably passes through the mounting plate 12. A connecting rod 31 is provided within the inner cavity of the placement slot 123. One end of the connecting rod 31 is mounted on the movable slider 251, and the end of the connecting rod 31 away from the movable slider 251 is provided with a drive plate 311. In this configuration, the placement slot 123 provides space for the connecting rod 31 to move, ensuring that the connecting rod 31 does not interfere with the mounting plate 12 when moving with the movable slider 251. The connecting rod 31 realizes the force transmission between the movable slider 251 and the drive plate 311. The drive plate 311, through its close engagement with the cam 322, becomes a key component for controlling the movement of the single-sided slider, providing structural support for switching to the single-handed exercise mode.

[0027] Furthermore, a threaded rod 321 is interlocked and penetrates the fixed housing 3. A knob 32 is located at the end of the threaded rod 321 away from the fixed housing 3, and the end of the threaded rod 321 away from the knob 32 is rotatably disposed within the cavity of the fixed housing 3. A cam 322 is provided on the threaded rod 321, and one end of the cam 322 is attached to the side wall of the drive plate 311. In this configuration, the engagement between the threaded rod 321 and the fixed housing 3 achieves helical transmission. The knob 32 provides a convenient manual adjustment component for staff or patients. By rotating the knob 32, the threaded rod 321 and the cam 322 can be moved axially, thereby changing the contact state between the cam 322 and the drive plate 311: when in contact, the drive plate 311 and the corresponding slider are locked; when separated, the single-sided structure is released, ultimately realizing the rapid switching between single-hand and double-hand exercise modes. The structural design is simple and the adjustment is precise, improving the ease of use of the device.

[0028] A hand-eye coordination rehabilitation aid method, the steps are as follows: Step 1: Flip the flip plate 11 so that it is perpendicular to the mounting housing 1, so that the housing 2 unfolds synchronously with the mounting plate 12. Confirm that the sliding balls 212 in the left arc-shaped channel 21 and the right arc-shaped channel 211 are placed securely, and check that the control components and the connections of each component are normal. Step 2: Start the hydraulic cylinder 22 through the control component of the housing 1, which drives the L-shaped mounting plate 221, electric push rod 222 and L-shaped plug rod 223 to move down. The L-shaped plug rod 223 is inserted into the positioning slot of the fixing plate 23, and simultaneously pulls the rectangular mounting cylinder 231, plug block 24 and connecting rod down, squeezing the vertical return spring 252. Step 3: Control the electric push rod 222 to drive the L-shaped plug rod 223 to separate from the fixed plate 23. The vertical return spring 252 rebounds and drives the moving slider 251 and the connecting rod to move upward, pushing the sliding ball 212 into the rectangular slot 121. The patient stares at the sliding ball 212 and presses it manually to complete the hand-eye coordination exercise. Step 4: When exercising with one hand, turn the knob 32 to move the threaded rod 321 and cam 322 away from the drive plate 311. The horizontal return spring 233 pops out the plug block 24, separating it from the rectangular mounting cylinder 231. Only the sliding ball 212 on one side slides out, which is suitable for one-handed exercise. Step 5: After exercise, the hydraulic cylinder 22 and electric push rod 222 are reset by controlling the components to return the sliding ball 212 to the arc-shaped channel, and the flip plate 11 is flipped to fit with the mounting housing 1, completing the storage for easy carrying.

[0029] The implementation principle of the hand-eye coordination rehabilitation assistive system of the present invention is as follows: Firstly, during hand-eye coordination rehabilitation, the patient flips the flip plate 11 so that it is perpendicular to the mounting housing 1. The operator then uses a control component (the specific control of which is based on existing technology) on the mounting housing 1 to control the hydraulic cylinder 22. This hydraulic cylinder 22 moves the L-shaped mounting plate 221 downwards. When the L-shaped mounting plate 221 moves downwards, it moves the electric push rod 222 downwards, which in turn moves the L-shaped insertion rod 223 downwards. Because the L-shaped plug rod 223 is inserted into the slot on the fixed plate 23, it can drive the fixed plate 23 to move downward. When the fixed plate 23 moves downward, it can drive the rectangular mounting cylinder 231 to move downward. When the rectangular mounting cylinder 231 moves downward, it can drive the plug block 24 to move downward. Therefore, the rectangular mounting cylinder 231 and the plug block 24 can respectively drive the right connecting rod 232 and the left connecting rod 241 to move vertically downward in the moving slide 25 and the moving slider 251, thereby squeezing the vertical return spring 252. At this time, the operator controls the electric push rod 222 through the control component. Therefore, the electric push rod 222 can separate the L-shaped plug rod 223 from the fixed plate 23, thus causing the fixed plate 23 to lose its limiting force. At this point, the previously compressed vertical return spring 252 can pop out, thereby driving the movable slider 251 to move on the movable slide groove 25. When the movable slider 251 moves, it can drive the rectangular mounting cylinder 231 and the plug block 24 upwards via the right connecting rod 232 and the left connecting rod 241 respectively. This allows the right connecting rod 232 and the left connecting rod 241 to drive the sliding balls 212 placed inside the left arc-shaped channel 21 and the right arc-shaped channel 211 to pop out. When the sliding balls 212 pop out, they can move within the rectangular slot 121 opened on the mounting plate 12. At this time, the patient... The user can complete hand-eye coordination rehabilitation exercises by watching the moving sliding ball 212 with their eyes and pressing the moving sliding ball 212 with their hand {(wherein, after being ejected, the sliding ball 212 can move by adsorption with the inner cavity of the rectangular slot 121 (specifically: a permanent magnet layer 1211 is embedded and attached to the inner wall of the rectangular slot 121, and the sliding ball 212 is made of magnetically conductive metal material such as carbon steel. When the sliding ball 212 is ejected into the rectangular slot 121 by the drive of the right connecting rod 232 and the left connecting rod 241, the permanent magnet layer 1211 will generate a continuous and moderate adsorption force on the sliding ball 212. This adsorption force can ensure that the sliding ball 212 always moves in contact with the inner wall of the rectangular slot 121 without falling off, and will not hinder the rolling of the sliding ball 212 due to excessive adsorption force)}; When a patient needs to exercise one hand, they can rotate knob 32, which in turn rotates threaded rod 321. This causes cam 322 to move away from drive plate 311, thus removing the limiting force from drive plate 311. Consequently, horizontal return spring 233 loses its compressive force, allowing it to eject plug block 24 from rectangular mounting cylinder 231. This separates rectangular plug block 24 from rectangular mounting cylinder 231, ensuring that only one sliding ball 212 can slide out during one-hand exercise. When not in use, the patient can close the flip plate 11 and the mounting housing 1 to store the device, making it easy to carry the hand-eye coordination rehabilitation device.

Only the sliding ball (212) on one side slides out, which is suitable for one-handed exercise. Step 5: After exercise, reset the hydraulic cylinder (22) and electric push rod (222) by controlling the components, return the sliding ball (212) to the arc-shaped channel, flip the flip plate (11) to fit with the mounting shell (1), and complete the storage for easy carrying.
