Description

Technical Field

[0001] This utility model relates to medical device technology, and more particularly to a device that can adapt to limb movement. Background Technology

[0002] Limb movement refers to the various actions and postural changes performed by the human body through the activity of skeletal muscle groups, utilizing the limbs, trunk, and head. These actions cannot be voluntary or unconscious; they are responses triggered by external stimuli. Adaptive devices are equipment capable of automatically adjusting their operating methods, parameters, and behaviors based on changes in the external environment, conditions, and internal states. These devices sense environmental changes and make adjustments based on this information to optimize performance, improve efficiency, and ensure safety.

[0003] Some wearable devices rely on preset motion patterns and fixed drive mechanisms (such as motors and pneumatic devices), lacking dynamic adjustment capabilities. In this case, the device can only provide motion assistance based on initially set parameters, and cannot flexibly adapt and adjust according to the wearer's immediate needs, nor can it accurately match the wearer's limb movement trends.

[0004] In existing technologies, some wearable devices rely primarily on fixed sensors and algorithms to monitor the user's movement. While they can provide basic motion data recording, they have significant limitations in terms of adaptive capabilities. Some wearable devices often cannot perceive and adapt to the wearer's limb movement trends in real time, resulting in an inability to effectively meet the user's personalized needs in practical use. Therefore, this paper proposes a limb movement adaptive device to address these issues. Utility Model Content

[0015] As a further description of the above technical solution:

[0016] The massage assembly includes multiple massage balls, which are fixedly connected to the outside of the arc-shaped lumbar support, and multiple lumbar support plates are fixedly connected to the outside of the arc-shaped lumbar support.

[0017] As a further description of the above technical solution:

[0018] One of the connecting components is externally fixedly connected to a foot plate, and an adjustment mechanism is fixedly connected to the top of the foot plate.

[0019] As a further description of the above technical solution:

[0020] The adjustment mechanism includes an arc-shaped plate, the bottom of which is fixedly connected to the top of the foot plate. An arc-shaped limiting plate is fixedly connected to the outside of the arc-shaped plate, and limiting teeth are fixedly connected to the outside of the arc-shaped plate.

[0028] 1. In this utility model, the rehabilitation personnel put their legs into the device, with the upper and lower legs respectively attached to the upper and lower U-shaped plates. When the sensor shell senses that the wearer has a tendency to move their legs, the self-starting cylinder pushes the telescopic column to move backward. Because the connecting block is connected to it, the backward force is transmitted to the lower U-shaped plate, thereby causing the lower U-shaped plate to rotate. The force of the rotation of the connecting column is also transmitted to the lower U-shaped plate, thereby causing the wearer's knee to bend, thus achieving the effect of adaptive limb movement for the wearer.

[0029] 2. In this utility model, the wearer puts the lumbar support on their waist, then pulls the buckle on the telescopic belt and inserts it into the fixed cavity. Because the limiting plate is limited by the hole inside the fixed cavity, it is firmly fixed to the wearer's waist. Then, the feet are placed on the footboard, and the arc-shaped connecting plate on the second arc plate is placed inside the cavity of the first arc plate and the arc-shaped limiting plate, and fixed and limited by teeth, thus adapting to different wearers. The above realizes the effect of diversified limb rehabilitation exercise of the device. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Reference Figure 1 , Figure 3 , Figure 5This utility model provides an embodiment of a limb movement adaptive device, comprising a sensing shell 1. The sensing shell 1 is generally circular in shape and is made of high-strength engineering plastic, which not only has good toughness and can resist external impacts and pressure to a certain extent, but is also relatively lightweight and will not cause too much burden to the user. A lower U-shaped plate 2 is rotatably connected inside the sensing shell 1. The lower U-shaped plate 2 is made of a strong and flexible metal material, such as aluminum alloy, and can rotate flexibly around the connection point with the sensing shell 1 within a certain range to adapt to different limb movements. An upper U-shaped plate 7 is also rotatably connected inside the sensing shell 1. The upper U-shaped plate 7 is also a "U"-shaped structure, also made of high-quality metal material, has good structural strength, and can rotate accordingly with limb movement and in coordination with other components. To ensure the flexibility and adaptability of the entire device, an adaptive mechanism providing adjustment force is fixedly connected to the top of the lower U-shaped plate 2. The adaptive mechanism includes a cylinder 3, which is cylindrical in shape. Its outer shell is made of aluminum alloy with a hard texture and excellent heat dissipation performance. The inside is equipped with key components such as a high-precision piston, piston rod, and sealing components. Through fine processing and assembly, the cylinder 3 can output power stably and efficiently. The bottom of the cylinder 3 is fixedly connected to the outside of the lower U-shaped plate 2. The drive end of the cylinder 3 is fixedly connected to a telescopic column 4. The telescopic column 4 is a slender cylinder made of smooth-surfaced, high-strength metal tubing. Driven by the cylinder 3, the telescopic column 4 can make smooth telescopic movements along its own axis to transmit power. A connecting block 5 is fixed to the outside of the telescopic column 4. The inside of the connecting block 5 rotates to the outside of the upper U-shaped plate 7.

[0041] A connecting post 6 is rotatably connected inside the lower U-shaped plate 2. The connecting post 6 is a straight metal rod made of medium carbon steel with excellent toughness and strength, possessing good torsional resistance. The connecting post 6 is rotatably connected to the outside of the upper U-shaped plate 7, and the outside of the upper U-shaped plate 7 is connected to the outside of the lower U-shaped plate 2. Two connecting components are fixedly connected to opposite sides of both the upper U-shaped plate 7 and the lower U-shaped plate 2. The connecting components include a connecting strip 8, which is a long, flat strip structure made of a soft and elastic fabric material, such as nylon, which is both durable and flexible. It can irritate human skin, and can stretch and deform appropriately with the movement of the human body. The external fixed connection of the connecting strap 8 is on the opposite side of the upper U-shaped plate 7 and the lower U-shaped plate 2. The external fixed connection of the connecting strap 8 is a Velcro 9. The Velcro 9 is a strip structure composed of many tiny hooks and fibers. One side has hooks and the other side has fibers. Its material has good wear resistance and adhesion. Through the mutual adhesion of the hooks and fibers, it can be connected and disassembled easily and quickly, making it convenient for users to adjust the tightness of the device according to their own needs.

[0042] Reference Figure 2 , Figure 4 , Figure 6 One of the connecting components is externally fixed to an arc-shaped lumbar support 10. The arc-shaped lumbar support 10 is shaped like a crescent moon, conforming to the physiological curve of the human waist, providing a perfect fit and all-around comfortable support. The outer layer is made of soft and breathable high-quality elastic fabric, which is not only gentle to the touch, avoiding friction and discomfort against the skin, but also highly breathable, preventing stuffiness even after prolonged wear. The inner layer is filled with a suitable amount of memory foam, which has unique slow-rebound properties. When subjected to pressure from the lower back, it can adaptively deform according to the pressure distribution and then slowly return to its original shape, providing continuous and even support. The arc-shaped lumbar support 10 is externally fixed to a massage component, which includes multiple massage balls 11. Each massage ball 11 is a standard spherical shape, smooth and rounded, like a small bead, allowing for precise contact with the lower back. Pressing on acupoints does not produce excessive pressure. The massage ball 11 is externally fixed to the outside of the curved waist support 10. The curved waist support 10 is externally fixed to multiple waist support plates 12. The waist support plates 12 are roughly long and curved, and their curvature matches the overall curvature of the curved waist support 10. The whole thing looks like a "reinforced skeleton" tailor-made for the curved waist support 10. The waist support plates 12 are mostly made of lightweight and high-strength carbon fiber material, which has excellent strength and toughness, but is very light in weight, so it will not add too much extra burden to the waist. At the same time, it also has good bending resistance, and can maintain its shape under various waist movements such as bending and stretching, providing stable and reliable support for the waist.

[0043] The external fixed connection of the arc-shaped waist support 10 is a telescopic strap 13. The telescopic strap 13 is long and strip-shaped, resembling a flat band, and has good elasticity. The material of the telescopic strap 13 is mainly a blend of high-elasticity rubber fibers and wear-resistant nylon fibers. The rubber fibers provide strong elasticity, allowing it to stretch and retract freely according to the body's size and different wearing tightness requirements, while the nylon fibers ensure its surface wear resistance, making it less prone to damage even after repeated stretching and friction. The external fixed connection of the telescopic strap 13 is a connecting strap 2 16, which is also a long and flat structure, similar in shape and material to the telescopic strap 13. The external fixed connection of the connecting strap 2 16 is a fixing cavity 17, which is rectangular in shape. The telescopic belt 13 has a hollow cavity structure, and the outer shell is made of a sturdy and durable engineering plastic. This plastic has high hardness and strength, which can effectively protect the internal components from external pressure, collision and other effects. The telescopic belt 13 is externally fixedly connected to a fixing mechanism, which includes a buckle plate 14. The buckle plate 14 has a small sheet-like structure on the outside, roughly rectangular in shape, and is made of a hard and tough plastic material, such as ABS plastic. It has good mechanical properties, is not easy to break, and has a smooth surface and good texture. The buckle plate 14 is externally fixedly connected to the outside of the telescopic belt 13. The buckle plate 14 is externally fixedly connected to a limiting plate 15. The limiting plate 15 is shaped like a long strip of thin plate and has protrusions on the outside for locking into the holes inside the fixing cavity 17.

[0044] Reference Figure 2 , Figure 4 , Figure 7Another connecting component has an externally fixed footplate 18. The footplate 18 will bend and translate accordingly with various foot movements, such as lifting, lowering, and twisting, always closely conforming to the foot and providing a stable support base. The top of the footplate 18 is fixedly connected to a support column 19. The support column 19 is made of high-strength stainless steel, which has extremely high strength and hardness, can withstand great pressure and weight, and also has good corrosion resistance, even in complex usage environments, such as contact with sweat and moisture. Under these conditions, it can maintain its stable performance for a long time. The top of the footplate 18 is fixedly connected to an arc-shaped plate 23. The arc-shaped plate 23 is made of a flexible plastic material, such as PP plastic, which has good plasticity and flexibility. It can undergo moderate elastic deformation with the bending and stretching movements of the foot without easily breaking. An arc-shaped connecting plate 24 is fixedly connected to the outside of the arc-shaped plate 23. The shape of the arc-shaped connecting plate 24 resembles a curved strip structure, extending along the outer edge of the arc-shaped plate 23. The overall curvature is similar to the arc... Matching the second-shaped plate 23, the external fixed connection of the arc-shaped connecting plate 24 has multiple fixed teeth 25. The fixed teeth 25 are shaped like small sawtooth protrusions, with relatively uniform size and relatively hard material, usually metal. If steel is used, it has strong wear resistance and biting ability. The external meshing connection of the fixed teeth 25 is to the outside of the limiting teeth 22, and the external sliding connection of the fixed teeth 25 is to the outside of the arc-shaped plate 20. The top of the foot plate 18 is fixedly connected to an adjustment mechanism, which includes the arc-shaped plate 20 and the arc-shaped plate 20. The material of 20 is a plastic material with certain toughness and strength, such as PVC plastic, which can play a basic supporting and guiding role in foot movement and adjustment. The bottom of the arc plate 20 is fixedly connected to the top of the foot plate 18. An arc-shaped limiting plate 21 made of hard plastic is fixedly connected to the outside of the arc plate 20. A limiting tooth 22 is fixedly connected to the outside of the arc plate 20. The shape of the limiting tooth 22 is adapted to the fixing tooth 25. The two work together through meshing to realize the adjustment and fixation function of the device in the relevant parts of the foot.

[0045] Working Principle: First, the sensing shell 1, as the external protective structure of the device, ensures durability and portability during movement through its high-strength engineering plastic material. The internal lower U-shaped plate 2 and upper U-shaped plate 7 are flexibly connected by a rotating joint, allowing them to rotate around the connection point to adapt to different limb movements. When the wearer begins to move, the sensors built into the sensing shell 1 monitor the movement trends of the limbs in real time. The cylinder 3, as the core component of the adaptive mechanism, adjusts the length of the telescopic column 4 based on the information fed back from the sensors, thereby changing the relative position of the lower U-shaped plate 2 and the upper U-shaped plate 7 to adapt to the wearer's posture. The rotating connection of the connecting column 6 ensures that the upper U-shaped plate 7 can flexibly respond to the movement of the lower U-shaped plate 2, maintaining the overall stability of the device.

[0046] In the lumbar region, the wearer puts the lumbar support 12 on their waist and then pulls the buckle 14 on the elastic band 13, inserting it into the fixing cavity 17. Because the limiting plate is limited by the holes inside the fixing cavity 17, it is firmly fixed to the wearer's waist, adaptable to wearers of different body types. The arc-shaped lumbar support 10, through its unique design and memory foam filling, can closely conform to the wearer's waist, providing comfortable support. During exercise, the multiple massage balls 11 of the massage component will provide moderate massage according to the movement changes of the waist, relieving fatigue.

[0047] The foot is placed on the footplate, and the arc-shaped connecting plate 24 on the arc-shaped plate 23 is placed inside the cavity of the arc-shaped plate 20 and the arc-shaped limiting plate 21, and fixed and limited by teeth, ensuring stable support for the foot in various movement states. Furthermore, a support column 19 is provided on the outside of the footplate 18 for the wearer to hold onto, providing additional support points. Through this combination of intelligent sensing and adaptive mechanisms, the device can adjust its structure in real time to ensure optimal support and comfort for the wearer in different movement states, significantly improving the wearing experience and exercise performance.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
