Description

Technical Field

[0001] This invention relates to the field of static muscle assessment and training devices, specifically a 360-degree static core muscle assessment and training device. Background Technology

[0002] The 360-degree static core muscle assessment and training device is a device used to assess and train the strength and stability of the core muscles. It typically consists of a circular platform and a posture sensor connected to the platform. After the user stands on the platform, the platform supports the user's hip joint. After support, the central platform tilts and rotates from 0 to 60 degrees. The posture sensor monitors the changes in the human body's position under the influence of gravity in real time during the rotation and tilting process. Based on the changes in the human body's position monitored by the posture sensor, the muscle strength index is calculated to assess the muscle status.

[0003] Addressing the pain points of traditional sports rehabilitation equipment, such as the lack of specialized isometric contraction adaptation functions, insufficient quantitative monitoring accuracy, and difficulty in matching personalized treatment plans, this product leverages the core value of isometric contraction in low-load joint rehabilitation and combines medical-grade technologies such as precision sensing and multimodal data integration. With the support of the "Healthy China 2030" policy for upgrading the rehabilitation service system of medical institutions, this product fills the market gap for professional isometric contraction rehabilitation equipment, meets the needs of efficient, accurate, and safe professional rehabilitation diagnosis and treatment in hospital rehabilitation departments, intensive care units, and other scenarios, and conforms to the trend of professionalization and intelligent development of medical rehabilitation equipment.

[0004] Therefore, based on this, and after research and improvement, a 360-degree static core muscle assessment and training device was proposed. Summary of the Invention (1)

[0006] 1. The technical problems solved by this implementation plan: Traditional sports rehabilitation equipment lacks isometric contraction-specific adaptation functions, has insufficient quantitative monitoring accuracy, poor personalized adaptability, and imperfect safety assurance mechanisms, making it difficult to meet the professional rehabilitation diagnosis and treatment needs of hospital rehabilitation departments, intensive care units, and other scenarios.

[0007] 2. The technical solution adopted in this implementation plan: a 360-degree static core muscle assessment and training device, including an upper surround bar and a chest frame handle. The upper surround bar is equipped with a position detection component. The chest frame handle is worn on the human chest. A support column is fixed at the bottom of the upper surround bar. From top to bottom, a hip joint support component, a leg positioning component, and an ankle positioning component are distributed on the surface of the support column. A standing platform is fixed at the bottom of the support column. A rotary drive housing is connected to the bottom of the standing platform. Rotary rods are connected to both sides of the rotary drive housing. A tilting drive housing is connected to the top side of the rotary rods.

[0008] 3. Beneficial effects of this implementation plan: It constructs a 360-degree rotation and tilt composite motion scenario, which can accurately simulate the force state of the core muscle groups under different postures; it provides two wearable component options to adapt to different user needs; it ensures the accuracy of evaluation data through multi-part positioning constraints; and it has a stable overall structure, laying the foundation for subsequent high-precision detection and intelligent evaluation.

[0009] 4. Working principle of this implementation plan: The user's lower body is fixed and constrained by the hip joint support component, leg positioning component and ankle positioning component to avoid interference from non-core muscle groups; the rotation drive housing drives the standing platform to rotate 360 ​​degrees, and the tilt drive housing drives the standing platform to tilt, forming a composite motion scenario; the position detection component collects the position or posture data of the user's core torso in real time, providing the basic conditions for core muscle group assessment and training. (2)

[0011] 1. Under optimal implementation conditions, the technical problem to be solved is to achieve high-precision location data acquisition of the human core trunk without blind spots, so as to ensure the quantitative accuracy of core muscle group assessment.

[0012] 2. In a preferred embodiment, the technical solution adopted is as follows: the position detection component consists of a first lidar and a second lidar distributed at right angles on the surface of the upper surrounding rod.

[0013] 3. Under optimal implementation conditions, the beneficial effects are as follows: the dual lidars are distributed at right angles, covering different directions of the human body respectively, achieving no blind spots in detection; the lidar has high ranging accuracy and can accurately capture changes in the distance between the human body and the equipment, providing reliable data support for evaluation.

[0014] 4. Working principle: Based on the principle of pulsed laser time-of-flight ranging, the first and second lidars emit pulsed lasers in the coronal and sagittal planes of the human body, respectively. By receiving the reflected lasers and calculating the flight time, real-time distance data is obtained and synchronously transmitted to the subsequent evaluation system. (3)

[0016] 1. Under optimal implementation conditions, the technical problems to be solved are: simplifying the installation structure of the detection components, improving the anti-interference ability of the detection, and accurately capturing the posture changes of the human core torso.

[0017] 2. In a preferred embodiment, the technical solution adopted is as follows: the position detection component is an attitude sensor, which is embedded inside the chest frame grip.

[0018] 3. Under optimal implementation conditions, the following beneficial effects are achieved: easy installation, rigid connection with the human body, and direct acquisition of torso posture data; unaffected by ambient light, debris, etc., resulting in strong detection stability; fast response speed, capable of capturing subtle posture changes and improving assessment accuracy.

[0019] 4. Working principle: The attitude sensor has built-in components such as gyroscopes and accelerometers to collect the angle and angular velocity data of the human core torso in three-dimensional space in real time. Through filtering algorithms, interference signals are eliminated, and attitude parameters such as pitch angle, roll angle, and yaw angle are calculated to reflect the stability of the torso. (4)

[0021] 1. Under optimal implementation conditions, the technical problem to be solved is: to provide a wearable component that can replace the chest brace grip, taking into account both human restraint and emergency protection functions, and to prevent users from experiencing stress swinging due to insufficient muscle exertion.

[0022] 2. In a preferred implementation, the technical solution adopted includes: a hand restraint assembly comprising a winding reel, connecting ropes, a chest strap, and wrist straps. The winding reel is elastically rotatably connected to the upper spiral rod via a torsion spring shaft. The connecting ropes are wound onto the surface of the winding reel, and a chest strap is fixed to the end of the connecting ropes away from the winding reel. A wrist strap is fixed to the surface of the chest strap. The length of each connecting rope is greater than the upper limit of the preset threshold of the position detection assembly. Exceeding the upper limit of the threshold of the position detection assembly indicates that the user's muscle strength is at its lowest assessment. A tension sensor is embedded in the surface of the winding reel, and the tension sensor is fixedly connected to the end of the connecting rope near the winding reel.

[0023] 3. Under optimal implementation conditions, the following beneficial effects are achieved: the wrist straps and chest straps can effectively restrain the upper body and prevent stress-induced swinging that could cause safety hazards; the tension sensor can monitor the tension of the connecting rope in real time, promptly determine the lowest muscle assessment level, and trigger the emergency mechanism; the torsion spring shaft can automatically rewind the connecting rope for easy reuse.

[0024] 4. Working principle: After the user wears the chest strap and puts the wrist straps on, when the standing platform tilts and rotates, if the muscles are not strong enough and the body tilts, the connecting rope will be released from the take-up reel. When the connecting rope is stretched beyond the upper limit of the threshold, the tension sensor is triggered. On the one hand, it determines that the muscle state is at the lowest level, and on the other hand, it continues to trigger for a certain period of time to start the platform to reset. After use, the torsion spring shaft releases elastic potential energy, which drives the take-up reel to wind up the connecting rope. (5)

[0026] 1. Under optimal implementation conditions, the technical problem to be solved is to achieve stable support and fit for the hip joint to prevent hip displacement during tilting and rotation, which would affect the assessment and training results.

[0027] 2. In a preferred embodiment, the technical solution adopted is as follows: the hip joint support assembly includes a back plate, a rotating shaft, and a front plate. The two ends of the back plate are rotatably connected to the front plate via the rotating shaft. A front support bracket is fixed to the inner side of the front plate, and a buckle is fixed to the outer side of any front plate.

[0028] 3. Under optimal implementation conditions, the following beneficial effects are achieved: the front panel can be rotated via a pivot axis to adapt to the hip contours of different users; the front support bracket directly conforms to the front of the hip, providing strong support stability; and the buckle provides a fixed base for tightening the straps, further enhancing the hip restraint effect.

[0029] 4. Working principle: After the user stands up, rotate the front panel to fit against both sides of the hip. The front support bracket makes close contact with the front of the hip. The front panel is locked and fixed by the buckle and tightening the strap, which provides stable support for the front of the hip and prevents displacement. (6)

[0031] 1. Under optimal implementation conditions, the technical problem to be solved is the need to further improve the tightness of the hip joint support, while adapting to the hip position of users of different heights to ensure consistent support effect.

[0032] 2. In a preferred embodiment, the technical solution adopted is as follows: a tightening strap is inserted inside the buckle, and one end of the tightening strap is fixedly connected to the outer side of another front plate; threaded rods are threadedly connected to both sides of the back plate, and a rear support bracket is rotatably connected to one end of the threaded rod through the back plate for fitting and supporting the rear side of the hip; the hip joint support assembly is driven by a motor screw or electric push rod to achieve vertical height adjustment to accommodate users of different heights.

[0033] 3. Under optimal implementation conditions, the following beneficial effects are achieved: the tightening strap and buckle work together to achieve a tight lock on the front of the hip; the threaded rod adjusts the position of the support bracket to form bidirectional support on the front and back of the hip, resulting in stronger fastening; the height adjustment function adapts to users of different heights, expanding the applicability of the device.

[0034] 4. Working principle: By pulling the tightening strap and locking the buckle, the front plates on both sides drive the front support bracket to clamp the front of the hip; rotating the threaded rod pushes the rear support bracket forward to fit the back of the hip to form support; the motor screw or electric push rod drives the hip joint support assembly to move up and down as a whole, adjusting to the hip position that matches the user's height to ensure targeted support. (7)

[0036] 1. Under optimal implementation conditions, the technical problem solved is: real-time feedback of position detection data is required to facilitate users in adjusting the initial posture, while also allowing users to intuitively understand the data changes during the evaluation process.

[0037] 2. In a preferred embodiment, the technical solution adopted is as follows: a positioning display screen is fixed to the front part of the surface of the upper ring rod, and the positioning display screen is connected to the position detection component through wires.

[0038] 3. Under optimal implementation conditions, the following beneficial effects will be achieved: real-time display of distance or attitude data collected by the position detection component, providing an intuitive reference for the user's initial attitude calibration; and enabling the user to monitor their own status in real time during the evaluation and training process, thereby improving the user experience.

[0039] 4. Working principle: The position detection component transmits the collected distance, attitude and other data to the positioning display screen through wires. The display screen visualizes the data and displays it. Users can adjust the initial attitude according to the displayed content to ensure that the data meets the initial evaluation requirements. (8)

[0041] 1. Under optimal implementation conditions, the technical problem to be solved is the need to achieve quantitative assessment of the core muscle group status based on test data, so as to provide data support for personalized rehabilitation programs.

[0042] 2. In a preferred implementation, the technical solution adopted is as follows: the position detection component is also connected to an evaluation system via wires; the evaluation system records the muscle parts exerted by the user at different rotation angles when the user is at a fixed tilt angle, and the evaluation system also evaluates the condition of each muscle part based on the change in the positional distance between different parts and the user's initial standing state under the action of gravity during the user's tilt and rotation process.

[0043] 3. Under optimal implementation conditions, the beneficial effects are: precise correspondence between muscle location and stress state is achieved, the assessment results are quantified and targeted; the recorded multi-dimensional data can form a user-specific muscle status profile, providing a basis for the development of personalized treatment plans.

[0044] 4. Working principle: The evaluation system pre-stores a database of standard muscle groups applying force under different tilt and rotation angles; after receiving the position spacing change data transmitted by the position detection component, it compares it with the initial standing state data, and combines it with the preset database to analyze the force stability and state level of each muscle group, and completes the quantitative evaluation. (9)

[0046] 1. Under optimal implementation conditions, the technical issues to be addressed include: providing an active emergency shutdown mechanism to ensure that users can quickly terminate operations during evaluation and training due to physical discomfort or other reasons, thus ensuring personal safety.

[0047] 2. In a preferred embodiment, the technical solution adopted is as follows: the grip part of the chest frame handle has a built-in pressure sensor. The pressure sensor is electrically connected to the rotary drive housing and the tilt drive housing through a wire. When the pressure sensor does not detect the human grip pressure, it automatically triggers the rotary drive housing and the tilt drive housing to stop working and controls the standing platform to reset.

[0048] 3. Under optimal implementation conditions, the following benefits are achieved: users can quickly trigger a stop and reset by actively releasing the handle, making operation convenient; emergency response is timely, avoiding the need for users to continue assessment or training in an uncomfortable state, thus reducing safety risks.

[0049] 4. Working principle: When the user holds the chest frame handle, the pressure sensor detects the grip pressure and maintains normal operation; when the user releases the handle due to physical discomfort or other reasons, the pressure sensor does not detect a pressure signal and immediately sends a stop signal to the rotary drive housing and the tilt drive housing. The drive housing stops working and controls the standing platform to return to the initial horizontal position. Attached Figure Description

Detailed Implementation

[0059] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0060] Example 1

[0061] like Figures 1-5 As shown, the present invention provides a technical solution: a 360-degree static core muscle group assessment and training device, including an upper surround rod 1 and a chest frame handle 14. The surface of the upper surround rod 1 is distributed with a first laser radar 3 and a second laser radar 4 at right angles. The length of each connecting rope 202 is greater than the upper limit of the preset threshold of the first laser radar 3 and the second laser radar 4. Exceeding the upper limit of the threshold of the first laser radar 3 and the second laser radar 4 means that the user's human muscles are assessed at the lowest level. The chest frame handle 14 is worn on the human chest. A positioning display screen 13 is fixed to the front of the surface of the upper surround rod 1, and the positioning display screen 13 is connected to the first laser radar 3 and the second laser radar 4 through wires.

[0062] The specific operation is as follows: the upper limit of the threshold of the first lidar 3 and the second lidar 4 represents the distance threshold of the user's position change during the tilting and rotation process. If the threshold is exceeded, it means that the muscle condition is at the lowest level or below. The user stands on the standing platform 9. After the hips are supported and stabilized, the chest brace handle 14 is put on the chest and the wrists of both hands are held on the handle. Then, when the standing platform 9 rotates and tilts forward from 0 to 60 degrees, the user exerts force with each muscle as the angle changes to try to maintain his own stability. If the muscle part does not exert enough force, the user will tilt at this time.

[0063] At this point, the distance between the first lidar 3 and the second lidar 4 and the human body will inevitably exceed the upper limit of the threshold. This indicates that the human body cannot stabilize itself. The first lidar 3 and the second lidar 4 can be replaced by a posture sensor. The posture sensor is embedded inside the chest frame handle 14. The posture sensor captures and compares the actual posture of the human body with the expected movement trajectory of the equipment in real time, thereby accurately quantifying the effort (i.e., force) that the patient puts into maintaining body stability.

[0064] Reference establishment: After the device is started, it will rotate 360° around its set tilt angle as the axis. This preset and regular motion trajectory is defined as a dynamic reference reference in space. The system will continuously simulate and update the spatial orientation of this reference.

[0065] Data acquisition: The posture sensor fixed to the patient, with the initial neutral position as the calibration zero point, begins to collect the angle and angular velocity data of the human body in three-dimensional space in real time and at high frequency. These data reflect all the posture adjustments (i.e. offset angles) made by the patient to resist the disturbances caused by the tilt and rotation of the device.

[0066] Intelligent computing and analysis: The algorithm within the system will synchronously receive dynamic reference data from the device and real-time posture data from the human body. By calculating the vector deviation between the two, the offset of the patient relative to the ideal motion state of the device at any time can be accurately calculated. This offset directly corresponds to the control force generated by the patient's muscle groups to resist disturbances and maintain balance.

[0067] Since the human body holds the handle with both hands, if the human body actively releases the handle, the pressure sensor on the handle will not detect pressure after the human body releases the handle. At this time, the system will automatically control the standing platform 9 to reset so as to end the user's muscle assessment or training in time. This is to avoid the user being unable to end the muscle assessment or training on their own under stress, and there is no need for additional personnel to turn the device on and off or accompany the user. This is to deal with emergencies (such as human discomfort) so as to actively control the end of the detection process.

[0068] like Figures 1-5As shown, a support column 5 is fixed to the bottom of the upper ring rod 1, and a hip joint support assembly 6, a leg positioning component 7, and an ankle positioning component 8 are distributed sequentially from top to bottom on the surface of the support column 5. The hip joint support assembly 6 includes a back plate 601, a rotating shaft 602, and a front plate 603. The two ends of the back plate 601 are rotatably connected to the front plate 603 through the rotating shaft 602. The hip joint support assembly 6 also includes a front support bracket 604 and a buckle 605. The front support bracket 604 is fixed to the inner side of the front plate 603, and the buckle 605 is fixed to the outer side of any front plate 603. The hip joint support assembly 6 also includes a tightening strap 606. The tightening strap 606 passes through the inside of the buckle 605, and one end of the tightening strap 606 is fixedly connected to the outer side of another front plate 603. 6 also includes threaded rods and a rear support bracket. Threaded rods are threaded to both sides of the back plate 601, and the rear support bracket is rotatably connected to one end of the threaded rods that passes through the back plate 601. A standing platform 9 is fixed to the bottom of the support column 5, and a rotary drive housing 10 is connected to the bottom of the standing platform 9. Rotary rods 11 are connected to both sides of the rotary drive housing 10, and a tilting drive housing 12 is connected to the top side of the rotary rods 11. The first lidar 3 and the second lidar 4 are also connected to an evaluation system via wires. The evaluation system records the muscle parts exerted by the user at different rotation angles when the tilt angle is fixed. The evaluation system also evaluates the condition of each muscle part based on the change in the distance between different parts of the user and the first lidar 3 and the second lidar 4 under the action of gravity during the tilt and rotation process.

[0069] The specific operation is as follows: The user stands on the standing platform 9 with the ankle part in close contact with the surface of the ankle positioning part 8, and the back of the thigh in close contact with the surface of the leg positioning part 7. The hip joint support component 6 can be adjusted up and down by a motor screw or electric push rod so that the back plate 601 moves to the user's hip joint. The user rotates the front plate 603 so that the front support 604 supports the front of the hip joint, and pulls the tightening strap 606 to tighten it and closes the buckle 605 so that the front support 604 provides stable support to the front of the hip joint.

[0070] Then rotate the threaded rod to extend its rear support to provide stable support to the back of the hip joint, thereby preventing the user from falling when tilting and rotating.

[0071] After the user stands up, the first lidar 3 and the second lidar 4, which are arranged at right angles, monitor the distance between themselves and the user in real time and display the distance on the positioning display screen 13. The user looks directly at the position display screen 13 and adjusts their posture to keep it in the initial position.

[0072] Then, by tilting the drive housing 12 to drive the rotating rod 11, the user tilts from 0 to 60 degrees. At the same time, the rotating drive housing 10 drives the standing platform 9 to rotate the user 360 degrees. During the user's tilting and rotation, based on the tilt angle and rotation angle, the evaluation system retrieves the muscle parts of the human body that exert force at that angle, and judges the muscle condition by real-time distance monitoring of the first lidar 3 and the second lidar 4. Specifically, when the first lidar 3 and the second lidar 4 have not rotated to the bottom, the farther the detected distance is, the worse the muscle condition is. When the first lidar 3 and the second lidar 4 have rotated to the bottom, the closer the detected distance is, the worse the muscle condition is.

[0073] The personnel are fixed by adding a hand restraint assembly 2, which includes a winding reel 201, a connecting rope 202, a chest strap 203, and a wrist strap 204. The connecting rope 202 is wound on the surface of the winding reel 201, and the chest strap 203 is fixed to the end of the connecting rope 202 away from the winding reel 201. The wrist strap 204 is fixed to the surface of the chest strap 203. A tension sensor is embedded in the surface of the winding reel 201, and the surface of the tension sensor is fixedly connected to the end of the connecting rope 202 near the winding reel 201. The winding reel 201 is elastically rotatably connected to the upper surrounding rod 1 through a torsion spring shaft.

[0074] The user stands on the standing platform 9. After the hips are supported and stabilized, the user puts the chest strap 203 on the chest and crosses the wrists and puts them inside the wrist straps 204. Then, as the standing platform 9 rotates and tilts forward from 0 to 60 degrees, the user exerts force with each muscle to try to maintain stability. If any muscle group does not exert enough force, the user will tilt. When tilting, the chest strap 203 moves with the body. At this time, the opposite connecting rope 202 is pulled to release it from the take-up reel 201. The connecting rope 202 is not fully released as long as the user's tilt distance does not exceed the upper limit of the threshold of the first laser radar 3 and the second laser radar 4. At this time, the chest strap 203 and wrist straps 204 do not affect the user's normal assessment and training of muscles.

[0075] After the connecting rope 202 is fully released, the tension sensor at its end is triggered by the force. At this time, the distance between the first lidar 3 and the second lidar 4 and the human body will inevitably exceed the upper limit of the threshold. This indicates that the human body cannot stabilize itself. At this time, the wrist strap 204 binds the human body's hands to the chest, thereby preventing the human body from swinging wildly due to stress reaction and causing safety hazards. Secondly, after the tension sensor is continuously triggered for a certain period of time, the system background determines that the user cannot continue to stand steadily. At this time, the system controls the standing platform 9 to reset so as to end the user's muscle assessment or training in time. This is to avoid the user being unable to end the muscle assessment or training on their own in a stress state, and there is no need for additional personnel to turn the device on and off or accompany the user.

[0076] After the user removes the chest strap 203 and wrist strap 204, the excess connecting rope 202 can be rewound based on the elastic potential energy of the torsion spring shaft for use in the next muscle assessment and training. The wrist strap 204 is an elastic band that makes it easy for the human hand to put on or take off.

[0077] In summary, when using this 360-degree static core muscle assessment and training device, the user first stands on the standing platform 9 with the ankles pressed against the surface of the ankle positioning piece 8 and the back of the thighs pressed against the surface of the leg positioning piece 7. The hip joint support component 6 can be adjusted up and down via a motor screw or electric push rod to move the back plate 601 to the user's hip joint. The user rotates the front plate 603 to make the front support bracket 604 support the front of the hip joint, and pulls the tightening strap 606 to tighten it and closes the buckle 605 to make the front support bracket 604 provide stable support for the front of the hip joint.

[0078] Then rotate the threaded rod to extend its rear support to provide stable support for the back of the hip joint, thereby preventing the user from falling when tilting and rotating. After the hip is supported and stabilized, put the chest strap 203 on the chest and cross your wrists and put them inside the wrist strap 204.

[0079] After the user stands up, the first lidar 3 and the second lidar 4, which are arranged at right angles, monitor the distance between themselves and the user in real time and display the distance on the positioning display screen 13. The user looks directly at the position display screen 13 and adjusts their posture to keep it in the initial position.

[0080] Then, by tilting the drive housing 12 to drive the rotating rod 11, the user tilts from 0 to 60 degrees. At the same time, the rotating drive housing 10 drives the standing platform 9 to rotate the user 360 degrees. During the user's tilting and rotation, based on the tilt angle and rotation angle, the evaluation system retrieves the muscle parts of the human body that exert force at that angle, and judges the muscle condition by real-time distance monitoring of the first lidar 3 and the second lidar 4. Specifically, when the first lidar 3 and the second lidar 4 have not rotated to the bottom, the farther the detected distance is, the worse the muscle condition is. When the first lidar 3 and the second lidar 4 have rotated to the bottom, the closer the detected distance is, the worse the muscle condition is.

[0081] When the standing platform 9 rotates and tilts forward from 0 to 60 degrees, the user exerts force with each muscle as the angle changes to try to maintain stability. If any muscle group does not exert enough force, the user will tilt.

[0082] At this point, the distance between the first lidar 3 and the second lidar 4 and the human body will inevitably exceed the upper limit of the threshold. This indicates that the human body cannot stabilize itself. At this time, the system will automatically control the standing platform 9 to reset. If the human body actively releases the grip, since the grip is equipped with a pressure sensor, the pressure sensor will not detect pressure after the human body releases the grip. At this time, the system will automatically control the standing platform 9 to reset in order to end the user's muscle assessment or training in time. This is to avoid the user being unable to end the muscle assessment or training on their own under stress, and there is no need for additional personnel to turn the device on and off or accompany the user. This is to deal with emergencies (such as human discomfort) and to actively control the end of the detection process.

[0083] Example 2

[0084] This embodiment aims to explain in detail the specific implementation process of a 360-degree static core muscle group assessment and training device based on the coordinated operation of a first lidar 3 and a second lidar 4. In this embodiment, a dual lidar with a right-angled distribution is used as the core position detection component. No alternative solution for the posture sensor is involved. The focus is on the signal acquisition, data transmission, evaluation and analysis of the lidar and the linkage control logic of the device.

[0085] I. Description of the structure of the device involved in the embodiments

[0086] The 360-degree static core muscle assessment and training device used in this embodiment includes an upper surround rod 1, a first lidar 3, a second lidar 4, a support column 5, a hip joint support assembly 6, a leg positioning component 7, an ankle positioning component 8, a standing platform 9, a rotation drive housing 10, a rotation rod 11, a tilt drive housing 12, a positioning display screen 13, a chest frame grip 14, and an assessment system. Wherein:

[0087] 1. The first lidar 3 and the second lidar 4 are fixedly installed on the surface of the upper ring rod 1. They are distributed at right angles and together constitute the position detection component. Their detection range can completely cover the key parts of the user's whole body (including the core muscle group related areas such as the torso and shoulders and neck) standing on the standing platform 9.

[0088] 2. The first lidar 3 and the second lidar 4 are electrically connected to the positioning display screen 13 and the evaluation system respectively via wires, and the distance data collected in real time can be synchronously transmitted to both of them;

[0089] 3. The evaluation system has a database of standard muscle groups required for the human body to maintain stability under different tilt angles (0-60 degrees) and different rotation angles (0-360 degrees), as well as the standard distance threshold range between the lidar and key parts of the human body at the corresponding angles.

[0090] 4. The support column 5 is fixed with a hip joint support component 6, a leg positioning component 7 and an ankle positioning component 8 from top to bottom, which are used to accurately position and constrain the user's lower body; the bottom of the standing platform 9 is connected to the rotary drive housing 10, and the two sides of the rotary drive housing 10 are connected to the tilt drive housing 12 through the rotating rod 11, which can realize the 360-degree rotation of the standing platform 9 and the 0-60 degree tilt adjustment.

[0091] II. Specific Implementation Steps

[0092] Step 1: Device initialization and parameter setting

[0093] Upon powering on the device, the evaluation system automatically completes initialization. Simultaneously, the first lidar 3 and the second lidar 4 enter a preheating state. After preheating, zero-point calibration is automatically performed to eliminate environmental interference errors. Based on training / evaluation requirements, the tilt angle of the standing platform 9 (selectable from 0-60 degrees, 30 degrees is selected in this embodiment), rotation rate (5° / s in this embodiment), and lidar detection frequency (10Hz in this embodiment, i.e., 10 sets of distance data are collected per second) are set via the device control panel. Based on the set tilt angle, the evaluation system automatically calls the standard distance threshold range at the corresponding angle (including the upper and lower limits of the standard distance between key parts such as the head, chest, waist, and hip and the dual lidars), and synchronously displays the standard threshold range on the positioning display screen 13.

[0094] Step 2: User Localization and Attitude Calibration

[0095] The user stands in the center of the standing platform 9, adjusting their posture so that their ankles are close to the ankle positioning piece 8 and the back of their thighs are close to the leg positioning piece 7. By adjusting the height of the hip joint support component 6 (which can be raised and lowered via a motor screw), the back plate 601 is aligned with the back of the user's hips. The front plate 603 is rotated so that the front support bracket 604 is aligned with the front of the hips. The tightening strap 606 is pulled and locked through the buckle 605. Then, the threaded rod is rotated to push the rear support bracket to further secure the hips, completing the lower body positioning constraint. The user then puts on the chest brace handle 14, holds the handle with both hands (the handle has a built-in pressure sensor for emergency stop triggering), and looks directly at the positioning display screen 13 to adjust their upper body posture. At this time, the first lidar 3 and the second lidar 4 begin to collect the initial distance data of the user's key parts in real time. The evaluation system compares the initial data with the preset initial posture standard distance. If the data is within the standard range, the positioning display screen 13 displays "Posture qualified, can start"; if the data is outside the range, the display screen prompts "Please adjust posture (e.g., head tilted to the left, waist tilted forward)" until the user adjusts to a qualified posture.

[0096] Step 3: LiDAR Collaborative Detection and Data Transmission

[0097] After the user's posture calibration is successful, the evaluation / training program is started via the control panel. The tilting drive housing 12 drives the rotating rod 11 to slowly tilt the standing platform 9 to a set angle of 30 degrees and maintain it fixed. Simultaneously, the rotation drive housing 10 drives the standing platform 9 to begin a 360-degree rotation at a set rate. During this process, the first lidar 3 and the second lidar 4 synchronously start detection at a set frequency of 10Hz. Both operate based on the pulsed laser time-of-flight (TOF) ranging principle. The specific working logic and coordination process are as follows:

[0098] I. Working principle and process of a single lidar radar:

[0099] 1. Transmission phase: Under the action of the driving circuit, the laser emitter inside the lidar periodically emits pulsed laser beams. After being collimated by the optical lens, the laser beams are directed at key parts of the user's body at a set divergence angle. The emission frequency is consistent with the preset detection frequency (10Hz).

[0100] 2. Receiving stage: When the pulsed laser beam shines on the user's body surface, some of the laser energy is diffusely reflected. The reflected light is focused by the receiving optical system of the lidar, captured by the photodetector, and converted into an electrical signal.

[0101] 3. Ranging Calculation Stage: The timing circuit inside the lidar accurately records the time difference between the laser pulse transmission and reception. Combining the speed of light c in a vacuum, using the formula Calculate the real-time distance between the lidar and the corresponding part of the user's body. (Dividing by 2 is because the laser needs to travel back and forth), the timing accuracy can reach the nanosecond level, ensuring that the ranging error is controlled within ±1mm;

[0102] 4. Data preprocessing stage: The signal processing module built into the lidar filters the calculated distance data to remove abnormal data caused by interference from ambient stray light (such as indoor lighting) and air scattering, and retains the effective distance data.

[0103] II. The collaborative working process of dual lidar:

[0104] 1. Time synchronization: The first lidar 3 and the second lidar 4 achieve time synchronization of transmission and reception through the synchronization clock signal of the evaluation system, so as to avoid mutual interference between the laser beams emitted by the two and ensure the consistency of data acquisition timing;

[0105] 2. Zonal Detection: The first lidar 3 is mainly responsible for collecting distance data in the coronal plane of the user (such as the distance between the left and right sides of the torso and the radar), and the coverage area of ​​its emitted laser beam is parallel to the coronal plane; the second lidar 4 is mainly responsible for collecting distance data in the sagittal plane of the user (such as the distance between the chest and back and the radar), and the coverage area of ​​its emitted laser beam is parallel to the sagittal plane. The detection areas of the two lidars form complementary coverage in the core area of ​​the user's body, with no detection blind spots.

[0106] 3. Data Fusion Preprocessing: The dual lidars transmit their preprocessed effective distance data to the evaluation system in real time via wires. The evaluation system first timestamps the two data streams, and then maps them to a unified user body coordinate system according to preset lidar installation position parameters, forming a preliminary three-dimensional distance data model of the user's core area. Finally, the preprocessed distance data and the preliminary three-dimensional data model are synchronously transmitted to the positioning display screen 13. The positioning display screen 13 dynamically displays the distance data curve, the schematic diagram of the preliminary three-dimensional data model, and the comparison with the standard threshold.

[0107] The complete process of dual-LiDAR collaborative detection and data transmission described above can be found in [reference]. Figure 6 The flowchart shown.

[0108] Step 4: Core muscle group status assessment and dynamic feedback

[0109] After receiving real-time distance data from dual lidar sensors, the evaluation system, based on a pre-set database of standard muscle groups requiring force application at different rotation angles, first identifies the core muscle groups that the user needs to focus on exerting force at the current rotation angle (e.g., the rectus abdominis and psoas major muscles requiring focus when rotating to 0°; the external oblique and erector spinae muscles requiring focus when rotating to 90°). Then, the real-time distance data is compared with the standard distance thresholds for the corresponding angle and corresponding muscle group to analyze the trend of distance changes.

[0110] 1. If the real-time distance data remains within the standard threshold range and the data fluctuation is less than ±5mm, the evaluation system determines that the corresponding core muscle group is stable and in good condition, and the positioning display screen 13 displays "Current muscle group condition: good";

[0111] 2. If the real-time distance data occasionally exceeds the upper limit of the standard threshold and the fluctuation range is between 5-10mm, the assessment system determines that the corresponding core muscle group is not exerting enough force and the stability is average. The positioning display screen 13 displays "Current muscle group status: average, it is recommended to strengthen the force" and at the same time emits a slight prompt sound through the device's built-in speaker.

[0112] 3. If the real-time distance data continuously exceeds the upper limit of the standard threshold (duration ≥ 2s), or the fluctuation range is greater than 10mm, the assessment system determines that the corresponding core muscle group is in poor condition and cannot maintain the current posture stability. The positioning display screen 13 displays "Current muscle group condition: poor, adjustment or stop is required".

[0113] At the same time, the assessment system records the changes in distance data at various angles during the user's 360-degree rotation and the corresponding muscle group status judgment results, forming a complete core muscle group assessment data archive.

[0114] Step 5: Emergency shutdown and device reset

[0115] During the evaluation / training process, the device will automatically initiate an emergency shutdown procedure if either of the following two situations occurs:

[0116] 1. If the distance data collected by the dual lidars continuously exceeds the standard threshold limit for ≥3s, the evaluation system determines that the user can no longer maintain a stable posture and immediately sends a stop command to the rotation drive housing 10 and the tilt drive housing 12. At the same time, it controls the standing platform 9 to stop rotating and slowly reset to a horizontal state.

[0117] 2. If the user releases the chest frame handle 14 due to physical discomfort or other reasons, the pressure sensor built into the handle will not detect the pressure signal, and an emergency stop will be triggered immediately, controlling the standing platform 9 to reset.

[0118] After the device is reset, the first lidar 3 and the second lidar 4 stop detecting. The evaluation system automatically saves the evaluation / training data and displays "Evaluation / training completed, data saved" on the positioning display screen 13.

[0119] III. Explanation of the Core Advantages of the Implementation Examples

[0120] This embodiment utilizes a right-angled design of the first lidar 3 and the second lidar 4 to achieve omnidirectional, blind-spot-free distance detection of the user's core muscle groups. Combined with coordinated movements of 360-degree rotation and fixed-angle tilt, it can accurately assess the force stability of each core muscle group under different postures. The high-frequency data acquisition capability of the dual lidars ensures the accuracy and real-time nature of the assessment results. Furthermore, through linkage with the assessment system, positioning display screen, and emergency shutdown mechanism, it guarantees the scientific rigor of the assessment / training while enhancing the safety of the device. The entire assessment / training process can be completed without the need for full-time assistance from personnel.

[0121] Example 3

[0122] Combination Figure 7 , Figure 8This embodiment aims to explain in detail the specific implementation process of a 360-degree static core muscle group assessment and training device based on a posture sensor. In this embodiment, a posture sensor embedded inside the chest frame grip is used as the core position detection component. It does not involve a lidar solution. The focus is on explaining the signal acquisition, posture calculation, data transmission, evaluation and analysis, and device linkage control logic of the posture sensor.

[0123] I. Description of the structure of the device involved in the embodiments

[0124] The 360-degree static core muscle assessment and training device used in this embodiment includes an upper surround bar 1, a support column 5, a hip joint support assembly 6, a leg positioning component 7, an ankle positioning component 8, a standing platform 9, a rotation drive housing 10, a rotation bar 11, a tilt drive housing 12, a positioning display screen 13, a chest frame grip 14, and an assessment system. Wherein:

[0125] 1. An attitude sensor is embedded inside the chest frame grip 14 and is rigidly connected to the chest frame grip 14 to form a core position detection component. The attitude sensor adopts a three-axis attitude and can collect the angle and angular velocity data of the human body in three-dimensional space (X-axis: left and right tilt direction, Y-axis: front and back tilt direction, Z-axis: left and right rotation direction) in real time. The sampling frequency is adjustable. The core detection object is the posture change of the user's core torso.

[0126] 2. The attitude sensor is electrically connected to the positioning display screen 13 and the evaluation system via wires, and can synchronously transmit the real-time collected attitude data (angle, angular velocity) to both; the chest frame grip 14 has a built-in pressure sensor, which is electrically connected to the evaluation system and is used for emergency stop triggering;

[0127] 3. The evaluation system has a database of standard muscle groups required for the human body to maintain stability under different tilt angles (0-60 degrees) and different rotation angles (0-360 degrees), as well as standard posture parameters of the human core trunk at the corresponding angles (including standard threshold ranges for pitch angle, roll angle, and yaw angle); at the same time, the evaluation system has a built-in dynamic reference generation module that can generate real-time dynamic reference references based on the device's tilt and rotation parameters.

[0128] 4. From top to bottom, the surface of the support column 5 is fixed with a hip joint support component 6, a leg positioning component 7, and an ankle positioning component 8, which are used to accurately position and constrain the user's lower body; the bottom of the standing platform 9 is connected to the rotary drive housing 10, and the two sides of the rotary drive housing 10 are connected to the tilt drive housing 12 through the rotating rod 11, which can realize the 360-degree rotation of the standing platform 9 and the 0-60 degree tilt adjustment. The rotary drive housing 10 and the tilt drive housing 12 have built-in angle sensors, which can transmit real-time tilt angle and rotation angle data to the evaluation system for dynamic benchmark calibration.

[0129] II. Specific Implementation Steps

[0130] Step 1: Device initialization and parameter setting

[0131] Upon powering on the device, the evaluation system automatically completes initialization, and the attitude sensor enters automatic calibration mode, correcting the alignment of its own coordinate system (right-hand Cartesian coordinate system) Y-axis with the direction of gravity. Based on training / evaluation requirements, key parameters are set via the device control panel: the tilt angle of the standing platform 9 (selectable from any fixed angle within the range of 0-60 degrees; 45 degrees is selected in this embodiment), rotation rate (3° / s in this embodiment), attitude sensor sampling frequency (20Hz in this embodiment, i.e., 20 sets of attitude data are collected per second), and attitude offset thresholds (in this embodiment, pitch / roll offset thresholds are set to ±8°, and yaw offset thresholds to ±10°). Based on the set tilt angle, the evaluation system automatically retrieves the standard human core torso attitude parameters (pitch angle: -5°~5°, roll angle: -3°~3°, yaw angle: -5°~5°) at the corresponding angle, and synchronously displays the standard parameter range and the set offset thresholds on the positioning display screen 13.

[0132] Step 2: User Localization and Attitude Calibration

[0133] 1. The user stands in the center of the standing platform 9 and adjusts his / her posture so that his / her ankle is close to the ankle positioning piece 8 and the back of his / her thigh is close to the leg positioning piece 7. By adjusting the height of the hip joint support component 6 (driven by the motor screw), the back plate 601 is close to the back of the user's hip. The front plate 603 is rotated so that the front support 604 is close to the front of the hip. The tightening strap 606 is pulled and locked by the buckle 605. Then the threaded rod is rotated to push the rear support to secure the hip, thus completing the lower body positioning constraint and preventing the lower body posture deviation from affecting the core muscle group assessment accuracy.

[0134] 2. The user wears the chest brace handle 14, adjusts the handle position so that the posture sensor is in the center of the chest (aligned with the midline of the sternum), and firmly grips the handle with both hands; the user maintains a natural standing posture and looks directly at the positioning display screen 13;

[0135] 3. Start the evaluation / training program through the control panel. The attitude sensor begins to collect initial attitude data and transmits it to the evaluation system. The evaluation system uses the average value of the initial data within 0.5s as the user's initial neutral position reference and locks the initial neutral position reference.

[0136] Step 3: Attitude sensor attitude detection and data transmission

[0137] After user posture calibration, the tilt drive housing 12 drives the rotating rod 11 to slowly tilt the standing platform 9 to a set 45-degree angle and hold it fixed; simultaneously, the rotation drive housing 10 drives the standing platform 9 to begin a 360-degree rotation at a set rate; during this process, the posture sensor starts real-time detection at a sampling frequency of 20Hz, transmitting the real-time rotation angle and tilt angle data to the evaluation system. The specific working logic is as follows:

[0138] I. Working principle and process of attitude sensor:

[0139] 1. Attitude Data Acquisition: Attitude sensors are typically based on different technologies, including gyroscopes, accelerometers, magnetometers, etc. These sensors can work individually or in combination to provide more accurate attitude information.

[0140] Gyroscope: Determines an object's orientation by measuring rotational motion. Based on changes in angular velocity, the angle of rotation of the object around its three axes can be calculated.

[0141] Accelerometer: Used to detect the acceleration of an object, thereby inferring its attitude. By integrating the acceleration value, the displacement of the object relative to a reference coordinate system can be obtained.

[0142] Magnetometer: Uses the Earth's magnetic field to determine the orientation of an object relative to the Earth. Combined with an accelerometer and gyroscope, it can achieve more accurate positioning.

[0143] Based on quaternions and special data fusion technology, this system calculates and outputs zero-drift 3D attitude and orientation data in quaternions and Euler angles in real time. This case uses Euler angle data (pitch angle: rotation angle around the X-axis, reflecting the torso's forward and backward tilt; roll angle: rotation angle around the Y-axis, reflecting the torso's left and right rotation; yaw angle: rotation angle around the Z-axis, reflecting the torso's left and right tilt).

[0144] 2. Data preprocessing: The attitude sensor has a built-in filtering module that uses a Kalman filter algorithm to remove abnormal data caused by slight human body shaking, device vibration, etc., and retain the effective data that reflects the changes in the core torso posture. At the same time, the sensor timestamps the real-time angle and angular velocity data to ensure the consistency of data timing.

[0145] II. Dynamic Benchmark Generation and Data Fusion:

[0146] 1. Dynamic Reference Base Generation: The evaluation system receives real-time rotation angle and tilt angle data transmitted from the rotary drive housing 10 and the tilt drive housing 12. The dynamic reference base generation module simulates the "attitude trajectory of the human core torso that should follow the device's movement under ideal stable conditions," which is the dynamic reference base. For example, when the device tilts at 45 degrees and rotates to 180 degrees, the human core torso should ideally maintain a slight pitch in the same tilt direction as the device, while the roll angle and yaw angle remain in their initial neutral positions. The system uses these ideal attitude parameters as the dynamic reference base at the current moment.

[0147] 2. Data fusion and comparison: The evaluation system timestamps the real-time attitude data (with timestamps) transmitted by the attitude sensor and the synchronously generated dynamic reference benchmark. The attitude offset between the two is calculated by vector operation (including pitch angle offset, roll angle offset, and yaw angle offset). The fused attitude offset data is synchronously transmitted to the positioning display screen 13, and the display screen dynamically displays the real-time trajectory of the three angles and the real-time trajectory of the rotation angle.

[0148] Step 4: Core muscle group status assessment and dynamic feedback

[0149] The assessment system uses posture offset data, combined with a pre-set database of standard muscle groups applying force at different rotation angles, to complete the assessment of core muscle group status.

[0150] 1. First, based on the real-time rotation angle, determine the core muscle groups that the user needs to focus on at the current angle (e.g., the rectus abdominis and psoas major muscles need to be focused when rotating to 0°; the external oblique and erector spinae muscles need to be focused when rotating to 90°; and the latissimus dorsi and gluteus maximus muscles need to be focused when rotating to 180°).

[0151] 2. Next, compare the angle value of the gravity direction in the real-time attitude data with the set tilt angle value, subtract the two values, calculate the offset in the gravity direction, and analyze the offset trend:

[0152] (1) If the offset is greater than or equal to 0, the evaluation system determines that the corresponding core muscle group is stable and in good condition;

[0153] (2) If the offset is less than 0, the evaluation system determines that the corresponding core muscle group is not strong enough and the stability is average.

[0154] (3) The smaller the offset, or the greater the fluctuation range in a continuous period of time, the assessment system judges that the corresponding core muscle group is in poor condition and cannot maintain the current posture stability.

[0155] Meanwhile, the assessment system records the user's posture deviation data, deviation trend, and muscle group status judgment results at various angles during the 360-degree rotation, forming a complete core muscle group assessment data archive containing timestamps, rotation angles, tilt angles, posture parameters, and assessment conclusions.

[0156] Step 5: Emergency shutdown and device reset

[0157] During the evaluation / training process, the device will automatically initiate an emergency shutdown procedure if either of the following two situations occurs:

[0158] 1. If any attitude offset continuously reaches or exceeds the set threshold for ≥3s, the evaluation system determines that the user can no longer maintain a stable attitude and immediately sends a stop command to the rotary drive housing 10 and the tilt drive housing 12. At the same time, it controls the standing platform 9 to stop rotating and slowly reset to a horizontal state.

[0159] 2. If the user releases the chest frame handle 14 due to physical discomfort or other reasons, the pressure sensor built into the handle will not detect the pressure signal, immediately triggering an emergency stop and controlling the standing platform 9 to reset. At the same time, the evaluation system saves the currently collected evaluation data.

[0160] After the device is reset, the posture sensor stops detecting, and the evaluation system automatically generates an evaluation / training report (including evaluation data curves, status scores for each muscle group, and training suggestions), and displays the evaluation / training report in the system.

[0161] III. Explanation of the Core Advantages of the Implementation Examples

[0162] This embodiment achieves direct and accurate detection of the user's core torso posture by embedding a posture sensor into the chest brace grip, offering the following key advantages: First, it is easy to install, simplifying the device structure and reducing installation and debugging difficulty; second, it has strong anti-interference capabilities, unaffected by external environmental factors such as indoor lighting and clutter, resulting in more stable detection accuracy; third, it has a fast response speed, with 20Hz high-frequency sampling capable of capturing subtle changes in core torso posture in real time, leading to more accurate evaluation results; and fourth, it has good user adaptability, as the posture sensor conforms to the body synchronously with the chest brace grip, accommodating users of different body types. Furthermore, through linkage with the evaluation system, dynamic benchmark generation module, and emergency shutdown mechanism, the scientific rigor and safety of the evaluation / training are ensured.
