Description

Technical Field

[0001] The present invention relates to the technical field of elderly training equipment, and specifically to an intelligent training device for wrist and hand functions for the elderly at home. Background Technique

[0002] With the development of social economy and the intensification of the aging population trend, the demand for elderly health care is increasing day by day. The progress of modern technology (such as intelligent sensing technology, Internet of Things, and artificial intelligence) provides technical support for home rehabilitation equipment. At the same time, the popularization of the home care model has promoted the R & D demand for professional rehabilitation tools in the home scenario. Against this background, the elderly wrist and hand training device came into being.

[0003] Traditional elderly home wrist and hand training devices mainly use mechanical springs or fixed weights to provide resistance. If the resistance is set too high, it is easy to cause excessive joint load or even injury to the elderly. If the resistance is set too low, it is difficult to achieve an effective training effect. In addition, traditional devices mostly adopt linear or single-plane motion designs and can only train in a single direction, which may lead to the lack of comprehensiveness in the coordination and flexibility of wrist muscle groups. Summary of the Invention

The auxiliary component 5 includes two connecting parts 504, which are located at the front end and the rear end respectively. A plurality of rotating parts 501 are evenly distributed inside the soft sleeve 6;

[0055] Connection grooves 502 are formed around the rotating parts 501 and the connecting parts 504. Connection springs 503 are arranged on the outer walls of the plurality of rotating parts 501 and the two connecting parts 504 near the connection grooves 502. A fixing seat 701 is fixedly connected to the lower part of the front end of the outer wall of the connecting box 3. A pressure sensor 703 is fixedly connected to the inner wall of the fixing seat 701 in a circle at the rear end. A fixing plate 706 is fixedly connected to the middle part of the outer wall of the silica gel plate 2 at the rear end. A plurality of second fixing blocks 705 are fixedly connected to the inner circle of the outer wall of the fixing plate 706 at the rear end.

[0056] After being processed by the control display panel 11, the rotation direction and strength of the first servo motor 402 and the second servo motor 403 are regulated according to a preset threshold value, driving the first contraction rope 406 and the second contraction rope 409 to retract and release. The double connecting parts 504 and the multiple rotating parts 501 of the auxiliary component 5 convert the tension of the contraction rope into a composite motion trajectory through the hinge structure of the horizontal axis and the vertical axis. The connection spring 503 compensates the elastic assistance in real time. These dynamic adjustment mechanisms can not only provide appropriate resistance to assist wrist training, but also simulate the natural motion trajectory of the joints, protect the joint safety in real time during the training process, and enable the elderly to gradually recover the wrist and hand functions in a comfortable state.

[0057] The rear-end connecting piece 504 is fixedly connected to the outer wall of the connecting frame 401. The outer walls of multiple rotating pieces 501 are all in contact with the inner wall of the soft sleeve 6. The multiple rotating pieces 501 are all hinged to each other to ensure the rigid connection between the auxiliary assembly 5 and the connecting frame 401. At the same time, through the fitting design of the hinge structure of the rotating piece 501 and the soft sleeve 6, a multi-degree-of-freedom composite motion trajectory is realized, enhancing the flexibility and naturalness of wrist training. In the middle of the front end of the inner wall of the connecting box 3, a first servo motor 402 is fixedly connected. The output end of the first servo motor 402 is fixedly connected to the outer wall of the corresponding first rotating shaft 404. Through the direct drive connection between the first servo motor 402 and the first rotating shaft 404, it is ensured that the retracting and releasing actions of the first retracting rope 406 respond quickly.

[0058] One end of the return spring 704 away from the second fixed block 705 is fixedly connected to the first fixed block 702. The rear end of the outer wall of the first fixed block 702 is fixedly attached to the pressure sensor 703. The linkage between the return spring 704 and the first fixed block 702 can transmit the hand pressure to the pressure sensor 703. On the upper end of one side inner wall and the lower end of the other side inner wall of the connecting frame 401, a second servo motor 403 is fixedly connected. The output end of the second servo motor 403 is fixedly connected to the outer wall of the corresponding second rotating shaft 407. The symmetric layout design of the two second servo motors 403 realizes the regulation of the second retracting rope 409, ensuring the resistance balance of the flexion and extension actions and avoiding joint injuries caused by motion deviation.

[0059] A battery panel 10 is arranged at the rear end of the inner wall of the connecting box 3. A fixing strip 8 is fixedly connected to the middle of the upper surface of the silica gel plate 2. The inner wall of the fixing strip 8 is fixedly connected to the outer wall of the soft sleeve 6. A control display panel 11 is arranged on the upper part of the connecting box 3 through a connecting wire. The battery panel 10 provides power for the device. The fixing strip 8 enhances the connection stability between the soft sleeve 6 and the silica gel plate 2. The control display panel 11 integrates the human-computer interaction function, has a simple and clear operation interface and operation process, and at the same time provides a convenient training management function, which can realize the interaction between the user and the device, facilitating the elderly to independently adjust the training parameters, view data and manage the training plan. A second magic tape 12 is arranged at the lower end of the fixing plate 1, and a first magic tape 9 is arranged at the lower end of the silica gel plate 2. The flexible fixing method of the first magic tape 9 and the second magic tape 12 not only ensures the convenience of device wearing, but also can flexibly adjust the tightness according to the user's arm size, improving the wearing comfort.

[0060] One end of the first retractable rope 406 and the second retractable rope 409 away from the connecting frame 401 penetrates through a plurality of connecting grooves 502 and is fixedly connected to the inner wall of the front-end connecting member 504. One end of the first retractable rope 406 away from the connecting member 504 is fixedly connected to the inner wall of the first rotating wheel 405. The first retractable rope 406 and the second retractable rope 409 penetrate through the connecting grooves 502 and are fixed to the connecting member 504 to ensure the stability of the tension transmission path. One end of the second retractable rope 409 away from the connecting member 504 is fixedly connected to the inner wall of the second rotating wheel 408. The connecting springs 503 are evenly distributed outside the first retractable rope 406 and the second retractable rope 409. The connecting springs 503 are distributed along the outer part of the retractable ropes. The sudden change of tension is buffered through elastic deformation to eliminate the sense of jerk of the moving part and ensure the smoothness of the training process.

[0061] The rear-end connecting member 504 is hingedly connected to the horizontal axis and the vertical axis of the corresponding rotating member 501, and the front-end connecting member 504 is hingedly connected to the horizontal axis and the vertical axis of the corresponding rotating member 501. The hinged connection of the horizontal axis and the vertical axis allows the connecting member 504 and the rotating member 501 to rotate relative to each other around the horizontal axis and the vertical axis respectively. The two-way hinged design of the horizontal axis and the vertical axis enables the rotating member 501 to simulate the composite motion mode of the wrist joint (such as rotation, lateral deviation, flexion and extension), improving the naturalness of training.

[0062] Working principle: The silica gel plate 2 is fixed to the front end of the arm through the first magic tape 9, fitting the position of the forearm. The fixing plate 1 is fixed to the back of the hand through the second magic tape 12 to ensure the overall stability of the device. The device has the function of personalized training guidance. It will combine the wrist and hand pathological conditions of the elderly and customize personalized training suggestions for them;

[0063] When the elderly perform wrist movements, the silica gel plate 2 moves with the arm, driving the fixed disk 706 to displace synchronously. When the fixed disk 706 rotates, the second fixed block 705 on its outer ring pushes the return spring 704 to compress, so that the first fixed block 702 tightly presses the pressure sensor 703. The pressure sensor 703 detects the dynamic pressure value in real time and transmits the signal to the control and display panel 11. The control and display panel 11 not only processes these signals, but also automatically adjusts the training plan according to the real-time training situation of the elderly to improve the pertinence and effectiveness of training. Subsequently, the control and display panel 11 starts the first servo motor 402 and the second servo motor 403, drives the first rotating shaft 404 and the second rotating shaft 407, and drives the first rotating wheel 405 and the second rotating wheel 408 to tighten the first retractable rope 406 and the second retractable rope 409. During this process, the device will monitor the training process of the elderly in real time, timely discover problems such as incorrect movements and excessive force, and provide feedback and adjustment suggestions through the control and display panel 11, which helps the elderly immediately adjust the training plan, avoid injuries caused by incorrect movements, and improve the safety of training;

[0064] The tensions of the first retractable rope 406 and the second retractable rope 409 are transmitted to the hinge structure through the connecting groove 502, driving multiple rotating members 501 to rotate around the horizontal axis and the vertical axis, so that the soft sleeve 6 wrapped outside it forms a composite motion trajectory (such as rotation, flexion and extension, lateral deviation) to simulate the activities of natural joints. The connecting springs 503 are distributed along the outer part of the retractable ropes, dynamically compensating for the tension fluctuations, eliminating motion jams, and ensuring a smooth and fluent training process. In addition, the device is convenient and easy to operate. Its control and display panel 11 has a simple and clear operation interface and operation process, which is convenient for the elderly to operate and use by themselves. The elderly can start wrist and hand training at any time at home without going to a professional rehabilitation institution, saving time and energy.
