However, in the early stages of rehabilitation, patients are unable to exercise independently, resulting in low device efficiency.

[0005] Therefore, a nursing rehabilitation exercise strength recovery device is proposed to address the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies and solve the problem that current nursing rehabilitation exercise strength recovery devices often use simple support rods for upper limb exercises, requiring patients to exercise using their own strength, but patients are unable to exercise independently in the early stages of rehabilitation, resulting in low device efficiency.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The nursing rehabilitation exercise strength recovery device of this utility model includes a base plate, a slide rail fixedly connected to the top of the base plate, and an adjustable seat assembly installed on the outer wall of the slide rail. An upper limb exercise assembly is provided on the top of the adjustable seat assembly, and a lower limb exercise assembly is provided on the side of the adjustable seat assembly. The upper limb exercise assembly includes a bottom support shell, a second bearing fixedly connected inside the bottom support shell, and a first threaded rod fixedly connected inside the second bearing. A slider is rotatably connected to the top of the first threaded rod, and a first worm gear is fixedly connected to the first threaded rod. A first worm is meshed on the side of the first worm gear, and a first bearing is fixedly connected to the bottom end of the first worm. A servo motor is installed at the top of the first worm. A first nut block is provided on the top of the first worm gear, and a top support shell is fixedly connected to the side of the first nut block. A first sliding groove is opened inside the top support shell, and a handle is fixedly connected to the top of the top support shell.

[0008] Preferably, the first threaded rod forms a rotating structure with the bottom support shell via the second bearing, and the first worm gear forms a rotating structure with the bottom support shell via the first bearing. The top support shell forms a lifting structure with the first nut block, the first threaded rod, and the bottom support shell.

[0009] Preferably, the servo motor forms a transmission structure through a first worm, a first worm wheel, and a first threaded rod, and the first worm and the first worm wheel mesh with each other.

[0010] Preferably, the lower limb exercise component includes a support frame, a leg support clip is fixedly connected to the top of the support frame, and a spring is fixedly connected to the side of the support frame. A buckle is fixedly connected to the end of the spring, and a locking block is engaged at the end of the buckle. A fixing plate is fixedly connected to the side of the locking block.

[0011] Preferably, the support frame and the slide rail form a sliding structure, and the support frame forms an elastic structure with springs, buckles, blocks and fixing plates.

[0013] Preferably, the second worm and the second worm wheel mesh with each other, and the second worm wheel and the second threaded rod are arranged with their vertical central axes coincident, and the second threaded rod and the second nut block form a threaded structure, and the seat body and the slide rail form a sliding structure.

[0014] The advantages of this utility model are:

[0015] 1. This utility model incorporates an upper limb exercise component. A servo motor drives a first worm gear and a first worm wheel, which in turn rotates a threaded rod, allowing the top support shell to rise and fall relative to the bottom support shell. This structural design makes height adjustment of the upper limb exercise component extremely convenient and precise. For patients of different heights or when different exercise positions are required during rehabilitation, quick adjustments can be easily achieved through motor control, eliminating the need for cumbersome manual operation and greatly improving the applicability and ease of use of the device. The threaded rod is rotatably connected to the bottom support shell via a second bearing, and the first worm gear is also rotatably connected to the bottom support shell via a first bearing. This bearing connection method ensures the stability of the components during rotation, reducing shaking and friction, making the entire upper limb exercise component more stable during lifting and lowering. Simultaneously, the cooperation between the first nut block and the threaded rod, as well as the relative motion structure design between the top and bottom support shells, through reasonable mechanical calculations, can withstand various forces applied by the patient during exercise, ensuring the structural strength and reliability of the device, improving safety, reducing potential safety hazards caused by structural instability, and enabling cyclic lifting and lowering of the device via the servo motor, allowing for better automatic training for patients in the initial stages.

[0016] 2. This utility model incorporates a lower limb exercise component. The support frame and slide rail form a sliding structure, allowing the lower limb exercise component to move freely on the base plate according to the patient's needs. For patients of different body types or those requiring simultaneous upper and lower limb training combinations, the position of the lower limb exercise component can be easily adjusted to fit the patient's body position, improving training comfort and effectiveness. While performing upper limb exercises, patients can easily place their lower limbs in a suitable position for leg exercises without significant body movement, reducing physical exertion and inconvenience, and enhancing the continuity and smoothness of the entire rehabilitation training process. The support frame, through springs, buckles, blocks, and a fixing plate, forms an elastic structure, adding elastic cushioning to lower limb exercises. When patients perform leg flexion and extension exercises, the springs absorb some of the impact force, reducing pressure on the leg joints during movement. This is particularly beneficial for patients with fragile joints or those in the early stages of rehabilitation, effectively preventing joint damage caused by excessive impact and providing protection. Simultaneously, the elastic structure makes the exercise process closer to the biomechanical characteristics of natural human movement, increasing the adaptability and diversity of training. Patients can adjust the resistance and difficulty of their exercises by using the elastic deformation of the springs, based on their own strength and recovery progress. This allows for personalized rehabilitation training, which helps to gradually increase leg muscle strength and joint flexibility, and promotes the recovery process.

[0017] 3. This utility model features an adjustable seat assembly. Through the meshing of a second worm gear and a second worm wheel, a second threaded rod rotates, causing the second nut block to move up and down, thus adjusting the seat height. This worm gear transmission method offers high transmission precision, accurately converting rotation into linear displacement, thereby precisely adjusting the seat to the patient's desired height. For patients of different heights or at different stages of rehabilitation training requiring different seat heights, this precise adjustment function ensures the patient remains in a comfortable and ergonomic sitting position, contributing to improved rehabilitation training effectiveness and patient engagement.

[0030] Please see Figure 4 According to the nursing rehabilitation exercise strength recovery device shown, the lower limb exercise component 2 includes a support frame 201. A leg support clip 202 is fixedly connected to the top of the support frame 201, and a spring 203 is fixedly connected to the side of the support frame 201.

The support frame 201 and the slide rail 4 form a sliding structure, and the support frame 201 forms an elastic structure through the spring 203, buckle 204, locking block 205 and fixing plate 206.

[0031] Please see Figure 5The illustrated nursing rehabilitation exercise strength recovery device includes an adjustable seat assembly 3 comprising a seat body 301. A second nut block 302 is fixedly connected to the bottom of the seat body 301, and a second threaded rod 303 is threadedly connected to the inside of the second nut block 302. A second worm gear 306 is fixedly connected to the end of the second threaded rod 303. A second worm 307 is meshed with the side of the second worm gear 306. A support plate 304 is rotatably connected to the bottom end of the second worm 307, and a turntable 305 is fixedly connected to the top end of the second worm 307. The second worm 307 and the second worm gear 306 mesh with each other, and the second worm gear 306 and the second threaded rod 303 are arranged with their vertical central axes coincident. The second threaded rod 303 and the second nut block 302 form a threaded structure, and the seat body 301 and the slide rail 4 form a sliding structure.

[0032] Working principle: First, the height adjustment of the upper limb exercise component 1 is achieved by a servo motor 111. When the servo motor 111 is started, the motor drives the first worm gear 102 to rotate. Since the first worm gear 102 meshes with the first worm wheel 105, the rotation of the first worm gear 102 causes the first worm wheel 105 to rotate. The first worm wheel 105 is fixed to the first threaded rod 106, so the first threaded rod 106 also rotates. During the rotation of the first threaded rod 106, the first nut block 107, which is threaded with it, moves up and down along the first threaded rod 106. Because the side of the first nut block 107 is connected to the top support shell 110, the top support shell 110 will move up and down with the movement of the first nut block 107, thereby driving the handle 112 fixed on the top support shell 110 to the appropriate height position. Patients can grip handle 112 to perform upper limb strength training tailored to their individual needs. This includes stretching exercises by pulling handle 112 up and down, or pushing handle 112 times forward and backward for precise exercises targeting different upper limb muscle groups. The handle height can be adjusted via a motor to achieve optimal training results. Simultaneously, the lower limb exercise component 2 facilitates lower limb rehabilitation training. The sliding structure design of the support frame 201 and slide rail 4 allows for easy left-right movement on the slide rail 4, enabling patients to adjust it to a suitable position based on their leg position. During training, the patient places their leg on the leg support clip 202 and begins leg flexion and extension movements. At this time, the elastic structure composed of spring 203, buckle 204, clip 205, and fixing plate 206 comes into play. As the leg flexes and extends, the spring 203 expands and contracts accordingly, providing a certain amount of elastic resistance. This not only increases the difficulty and intensity of the training, effectively exercising leg muscle strength and endurance, but also acts as a buffer during leg movements, reducing the impact on the leg joints and protecting them. This is particularly suitable for patients in the early stages of rehabilitation or those with fragile joints. Furthermore, by adjusting the elastic coefficient of the spring 203 or changing the engagement position of the latch 204 and the block 205, the training resistance can be flexibly adjusted to meet the personalized training needs of different patients at different stages of rehabilitation. The adjustable seat assembly 3 also plays a crucial role throughout the entire rehabilitation training process. By rotating the turntable 305, the second worm gear 307 connected to it is driven to rotate. Since the second worm gear 307 and the second worm wheel 306 mesh with each other, the rotation of the second worm gear 307 will drive the second worm wheel 306 to rotate. The second worm wheel 306 and the second threaded rod 303 are coaxially arranged, and the second threaded rod 303 and the second nut block 302 form a threaded transmission structure. Therefore, the second threaded rod 303 will rotate with the rotation of the second worm wheel 306, thereby causing the second nut block 302 to move up and down, and finally realizing the height adjustment of the seat body 301.This design ensures that patients can maintain a comfortable, ergonomic sitting posture during training, effectively reducing fatigue and discomfort caused by prolonged training. Simultaneously, the sliding cooperation between the seat body 301 and the slide rail 4 allows it to move back and forth on the slide rail 4, facilitating quick and convenient adjustment of the relative position between the patient and the upper limb exercise component 1 and the lower limb exercise component 2. This makes the entire rehabilitation training process smoother and more efficient, further improving the quality and effectiveness of rehabilitation training and meeting the diverse rehabilitation training needs of different patients.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
