Description

Technical Field

[0001] This invention relates to the field of rehabilitation training equipment technology, specifically to a device for testing and exercising balance ability in middle-aged and elderly patients. Background Technology

[0002] With the increasing aging of the global population, maintaining the independent living ability and quality of life of middle-aged and elderly people has become an important public health issue. Among these issues, balance ability is a key factor determining the mobility of the elderly and preventing falls. Falls are one of the leading causes of trauma, disability, and even death among the elderly, placing a heavy burden on individuals, families, and society. Traditional methods of balance training, such as using balance boards and walking in straight lines, cannot capture subtle postural swaying and muscle adjustment processes. Users cannot know their performance and the degree of improvement, resulting in insufficient motivation. For those with poor balance, there is a risk of falls, and falls can easily lead to fractures and other difficulties for the elderly.

[0003] Existing technologies, such as Chinese invention patent CN202210553197, disclose a "balance training device for rehabilitation medicine." This device, through the cooperation of a base plate and support seat, aims to improve the protection of the trainee, preventing excessive tilting during training that could lead to falls and injuries. It addresses the technical problem that existing balance training devices for rehabilitation medicine typically use elastic safety belts, which age over time, reducing their protective effect and causing falls. Improving protection for the elderly is crucial to prevent injuries during training. Elderly individuals often lack balance and cannot actively adjust their center of gravity to maintain balance, making it even more difficult when facing slopes. Guiding the elderly in maintaining their center of gravity is an effective way to restore their balance, helping them to be more stable when facing slopes. Summary of the Invention

[0004] The purpose of this invention is to provide a method that can observe the center of gravity direction of the elderly, thereby facilitating guidance for the elderly to adjust their center of gravity, and at the same time, to create a slope environment so that the elderly can adapt to the slope environment from multiple angles.

[0005] To achieve the above technical effects, the present invention is realized through the following technical solutions: A device for testing and exercising the balance ability of middle-aged and elderly patients, characterized in that it includes a support mechanism and an auxiliary mechanism. The support mechanism includes a base. An adjustment cavity is provided inside the base. A first motor is arranged inside the adjustment cavity. The output end of the first motor is fixedly connected to a worm. Sliding grooves are symmetrically provided on the outside of the base. A control panel is provided at the front end of the base. A staircase is provided behind the base. A support frame is provided at the side end of the base. A baffle is slidably installed on the support frame. A protective plate is provided at the top and bottom; The auxiliary mechanism includes an adjustment seat slidably installed in the sliding groove. A turbine meshing with the worm is provided at the bottom of the adjustment seat. A support cylinder is provided at the top of the adjustment seat. A second motor is provided at the bottom of the support cylinder. A sun gear is provided at the output end of the second motor. A turntable is rotatably installed at the top of the support cylinder. A plurality of planet gears are rotatably installed at the bottom of the turntable. A toothed ring is provided on the inner wall of the support cylinder. The toothed ring meshes with the planet gears. The planet gears mesh with the sun gear.

[0006] Further, the baffle is of a concave structure. A handle is provided inside the baffle. A sliding cylinder is provided at the corner of the baffle. The sliding cylinder is slidably installed on the support frame. The sliding cylinder and the support frame are connected by a pin. Straps are provided on the two outer sliding cylinders. The straps are connected by buckles.

[0007] Further, an adjustment groove is provided on the protective plate. The adjustment groove is of a "middle" shape structure and is adapted to the turbine and the second motor.

[0008] Further, support plates are provided on both sides of the adjustment seat. A slider is provided on one side of the support plate. The slider is adapted to the sliding groove.

[0009] Further, four pressure plates are symmetrically arranged at the center of the top of the turntable. A pressure sensor is provided at the bottom of the pressure plate. The pressure sensor is electrically connected to the control panel. Anti-slip patterns are provided on the top of the pressure plate. A plurality of rotating shafts are equidistantly arranged at the bottom of the turntable. The rotating shafts are rotatably connected to the planet gears.

[0010] Compared with the related technology, a device for testing and exercising the balance ability of middle-aged and elderly patients provided by the present invention has the following beneficial effects:

[0011] 1. By setting the support mechanism and the auxiliary mechanism, the first motor drives the worm, and the cooperation of the worm and the worm gear drives the adjustment seat to rotate. The inclination of the adjustment seat causes the turntable to tilt accordingly, enabling the elderly to stand on the slope to exercise their balance ability. In addition, through the second motor and the planetary gear set, the turntable rotates, thereby changing the state of the elderly on the slope, so as to create various environments to exercise the balance ability of the elderly.

[0012] 2. This invention uses a turntable with four pressure plates and pressure sensors to monitor the pressure on the user's soles and heels. By analyzing the pressure changes between the soles and heels, as well as between the left and right feet, the invention can determine whether the elderly person's center of gravity adjustment is appropriate in different environments, thus providing timely guidance.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example 1

[0024] See Figures 1 to 6 As shown, a device for testing and exercising balance ability in middle-aged and elderly patients is characterized by comprising a support mechanism 1 and an auxiliary mechanism 2. The support mechanism 1 includes a base 11, an adjustment cavity 111 inside the base 11, a primary motor 12 inside the adjustment cavity 111, a worm gear 13 fixedly connected to the output end of the primary motor 12, symmetrical sliding grooves 112 on the outer side of the base 11, a control panel 14 at the front end of the base 11, a staircase 15 at the rear of the base 11, a support frame 16 at the side end of the base 11, a baffle 17 slidably mounted on the support frame 16, and a bottom and top section. The auxiliary mechanism 2 includes an adjustment seat 21 slidably installed in a slide groove 112. The bottom of the adjustment seat 21 is provided with a turbine 22 that meshes with a worm gear 13. The top of the adjustment seat 21 is provided with a support cylinder 23. The bottom of the support cylinder 23 is provided with a second motor 24. The output end of the second motor 24 is provided with a sun gear 25. The top of the support cylinder 23 is rotatably mounted with a turntable 26. The bottom of the turntable 26 is rotatably mounted with multiple planetary gears 27. The inner wall of the support cylinder 23 is provided with a gear ring 28. The gear ring 28 meshes with the planetary gears 27. The planetary gears 27 mesh with the sun gear 25. The elderly person is assisted to stand on the turntable 26 via stairs 15, and then protected by a baffle 17. Next, motor 12 and motor 24 are activated via control panel 14. After motor 12 is activated, it drives worm gear 13 to rotate. The cooperation of worm gear 13 and turbine 22 drives adjustment seat 21 to rotate. After adjustment seat 21 rotates, it tilts, causing turntable 26 where the elderly person is standing to tilt, thus simulating a ramp environment. At the same time, motor 24 drives sun gear 25 to rotate. The cooperation of sun gear 25, planet gear 27 and ring gear 28 forms a planetary gear system. Planet gear 27 rotates around turntable 26, thus causing turntable 26 to rotate. In this way, turntable 26 causes the elderly person to rotate, changing the elderly person's orientation on the ramp, simulating uphill and downhill states.

[0025] The baffle 17 is of a concave structure. A handle 171 is provided inside the baffle 17, and a sliding cylinder 172 is provided at the corner of the baffle 17. The sliding cylinder 172 is slidably installed on the support frame 16, and the sliding cylinder 172 and the support frame 16 are pin-connected. Straps 173 are provided on the two outer sliding cylinders 172, and the straps 173 are connected through buckles 174. By means of the handle 171, the elderly can hold it to ensure their own stability. At the same time, the baffle 17 is sealed by the straps 173 and the buckles 174, so that the elderly are restricted inside the baffle 17, thereby improving the protection ability of the elderly. The pin connection enables the sliding cylinder 172 to slide on the support frame 16, so that the height of the baffle 17 can be adjusted according to the height of the elderly, which is convenient for the elderly to hold the handle 171.

[0026] An adjustment groove 181 is provided on the protection plate 18. The adjustment groove 181 is of a "middle" shape structure and is adapted to the turbine 22 and the second motor 24. By providing the adjustment groove 181, the turbine 22 and the second motor 24 are not interfered during rotation. At the same time, by arranging the second motor 24 at the bottom of the adjustment seat 21, the gap between the adjustment seat 21 and the base 11 can be reduced, and the stability of the adjustment seat 21 can be improved.

[0027] Support plates 211 are provided on both sides of the adjustment seat 21. A slider 212 is provided on one side of the support plate 211, and the slider 212 is adapted to the chute 112. Through the cooperation of the slider 212 and the chute 112, the adjustment seat 21 can be driven to rotate under the cooperation of the turbine 22 and the worm 13, so that the adjustment seat 21 is more stable after tilting.

[0028] Four pressure plates 261 are symmetrically arranged at the top center of the turntable 26. A pressure sensor 262 is provided at the bottom of the pressure plate 261, and the pressure sensor 262 is electrically connected to the control panel 14. Anti-slip patterns are provided on the top of the pressure plate 261. Multiple rotating shafts 263 are equidistantly arranged at the bottom of the turntable 26, and the rotating shafts 263 are rotatably connected to the planet gears 27. The weight of the elderly is evenly distributed by the four pressure plates 261. For example, the two pressure plates 261 on one side are respectively located at the positions of the sole and the heel. By monitoring the pressure changes of the pressure plates 261 at the sole and the heel, the direction of the elderly's center of gravity is judged.

[0029] Embodiment 2

[0030] A support for installing the worm 13 is provided in the adjustment cavity 111 of the present invention;

[0031] The control panel 14 of the present invention is an external power supply;

[0032] The chute 112 of the present invention is coaxial with the turbine 22;

[0033] The support cylinder 23 and the turntable 26 of the present invention can be connected by bearings.

[0034] Example 3

[0035] Working principle: Before use, adjust the height of the slide cylinder 172 on the support frame 16 to a suitable level using the pin. Then, the user stands on the turntable 26 and seals the baffle 17 with the strap 173. After ensuring safety, start the first motor 12 through the control panel 14. The first motor 12 drives the worm gear 13 to rotate. The turbine 22 fixed at the bottom of the adjustment seat 21 meshes with the worm gear 13 for transmission. Through the self-locking characteristics of the worm gear 13, the tilt angle of the adjustment seat 21 can be kept stable. The rotation of the turbine 22 causes the entire adjustment seat 21 to tilt at a certain angle. Since the support cylinder 23, turntable 26, etc. are all installed on the adjustment seat 21, the plane of the turntable 26 also tilts accordingly, thus creating a slope environment similar to going uphill or downhill for the user standing on it.

[0036] While the turntable 26 is tilted or started independently, the second motor 24 is started via the control panel 14. The second motor 24 drives the sun gear 25 to rotate. The sun gear 25 meshes with multiple planet gears 27 arranged around it. The planet gears 27 mesh with the gear ring 28 fixed to the inner wall of the support cylinder 23, forming a planetary gear system. In this system, the sun gear 25 acts as the driving element, the gear ring 28 is fixed, and the power will drive the planet gears 27 to not only rotate on their own axis, but also revolve around the sun gear 25. The planet gears 27 drive the turntable 26 to rotate slowly through the rotating shaft 263. The rotation of the turntable 26 causes the user's orientation on the slope (e.g., facing uphill, facing downhill, or sideways to the slope) to change continuously, thereby simulating the complex situation of needing to turn and adjust posture on a slope in real life, and comprehensively training the user's balance and adaptability from multiple angles.

[0037] The user stands on four pressure plates 261 symmetrically arranged at the top center of the turntable 26. These four plates can sense the pressure of key parts of the user's feet, such as the soles and heels. Each pressure plate 261 is equipped with a pressure sensor 262 at its bottom to collect pressure data at each point in real time. The pressure sensor 262 transmits the collected pressure signal to the control panel 14. The processing system in the control panel 14 analyzes the data and, by calculating the pressure distribution differences between the two feet and between the front and back of a single foot (sole and heel), can accurately determine the user's real-time center of gravity shift direction and stability. This information can be displayed on the screen of the control panel 14 in the form of graphics or data, allowing for a direct observation of how the center of gravity position changes with the ramp environment.
