[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0040] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0041] See also Figures 1 to 4 In a preferred embodiment of the present utility model, based on the above problems existing in the prior art, a joint state detection device is provided, comprising:

[0042] The frame body 1 includes a first supporting member 11 and a second supporting member 12, wherein the first supporting member 11 is rotatably connected to the second supporting member 12;

[0043] The first supporting member 11 and the second supporting member 12 are respectively fitted to the limbs on both sides of the joint through a plurality of connecting belts 2, and the connecting hinge of the first supporting member 11 and the second supporting member 12 is fitted to the joint;

[0044] The multi-sensory sensor module 3 is installed on the frame body 1 and is used to detect multi-sensory sensor information during joint movement;

[0045] The control module 4 is installed on the frame body 1. The control module 4 is electrically connected to the multi-sensory sensor module 3 and the power supply component 5 respectively, and is used to receive and pre-process the multi-sensory sensor information.

[0046] Specifically, the functional design of existing joint status detection devices is relatively simple, focusing only on the detection of a single parameter, namely the joint angle, ignoring the diversity and comprehensiveness that needs to be considered in the assessment of joint health status.

[0047] The device of this embodiment mainly includes a frame body 1, a connecting belt 2, a multi-sensory sensor module 3, a control module 4, and a power supply component 5; wherein the frame body 1 is composed of a rotatably connected first support component 11 and a second support component 12, which are connected to each other through a precisely designed connection structure to ensure that the first support component 11 can rotate freely relative to the second support component 12 to adapt to changes in joint movement. The connecting belt 2 is installed on the first support component 11 and the second support component 12 respectively to ensure that it can accurately fit the limb parts on both sides of the joint, and at the same time ensure that the first support component 11 and the second support component 12 are tightly fitted to the joint itself at the connection in the middle of the joint, so as to achieve stable contact between the device and the joint.

[0048] A multi-sensory sensor module 3 is introduced on the surface of the device, which can capture multi-dimensional sensory information during joint movement in real time, such as but not limited to the bending angle of the joint, temperature changes, whether there is abnormal sound and other multi-dimensional parameters. The control module 4 is responsible for receiving and preliminarily processing the various sensor information collected by the multi-sensory sensor module 3, integrating the multi-dimensional data and performing preliminary analysis, so as to comprehensively reflect the health status of the joint and provide comprehensive data support for subsequent joint health status assessment.

[0049] The power supply component 5 can power the entire device and provide different voltages to adapt to different sensors in the multi-sensory sensing module 3.

[0050] This embodiment significantly improves the single-function defect of traditional joint status detection devices by integrating advanced multi-sensory sensing technology. It can not only accurately detect joint angles, but also fully monitor various key physiological parameters during joint movement, thereby providing strong technical support for comprehensive evaluation of joint health status and precise rehabilitation.

[0051] As a preferred embodiment, wherein Figure 2 As shown, the first supporting member 11 has a first mounting portion 110;

[0052] The second supporting member 12 has a second mounting portion 120;

[0053] The first mounting portion 110 or the second mounting portion 120 is provided with an arc-shaped hole around the central axis;

[0054] A threaded fastening assembly 13 for limiting the relative rotation between the first supporting component 11 and the second supporting component 12 is disposed in the arc-shaped hole. The threaded fastening assembly 13 is connected between the first mounting portion 110 and the second mounting portion 120 .

[0055] Furthermore, a plurality of arc-shaped holes are provided, and the plurality of arc-shaped holes are arranged along the circumference of the central axis of the mounting portion, and a threaded fastening component is provided in each arc-shaped hole.

[0056] The plurality of arc-shaped holes include two first arc-shaped holes 1201a and two second arc-shaped holes 1201b; the two first arc-shaped holes 1201a are arranged opposite to each other in a first direction; the two second arc-shaped holes 1201b are arranged opposite to each other in a second direction. Preferably, the first direction is perpendicular to the second direction.

[0057] In this embodiment, the threaded fastening component 13 can be a combination of a screw and a nut, a combination of a bolt and a nut, or a combination of a screw and a nut 13. As long as it is a component with a threaded tightening function, it can limit the relative rotation of the first support component 11 and the second support component 1.

[0058] Furthermore, the first supporting component 11 also has a first fixing portion 111, and the first fixing portion 121 is integrally formed with the first mounting portion 110; the second supporting component 12 also has a second fixing portion 121, and the second fixing portion 121 is integrally formed with the second mounting portion 120; the first fixing portion 111 and the second fixing portion 121 are attached to the limb parts on both sides of the joint.

[0059] As a preferred embodiment, it further includes: an O-type gasket (not shown in the figure), which is sleeved on the screw of the threaded fastening component 13 and abuts between the first mounting portion and the second mounting portion.

[0060] Specifically, by setting an O-ring gasket, its annular structure can fill the gap between the first mounting portion 110 and the second mounting portion 120, and play a good buffering role during the relative rotation of the first support component 11 and the second support component 12, reducing vibration and noise, further improving the stability and vibration reduction effect of the device, enhancing the overall structural strength of the device, and also helping to extend the service life.

[0061] Furthermore, the frame body 1 may also include a fixing plate 14, the threaded fastening assembly 13 is connected between the first mounting portion 110, the second mounting portion 120 and the fixing plate 14, and the O-ring gasket fills the gap between the first mounting portion 110 and the second mounting portion 120, and the gap between the second mounting portion 120 and the fixing plate 14, further enhancing the stability of the frame body 1.

[0062] As a preferred embodiment, the multi-sensory sensing module 3 includes: an angle sensor 31, which is arranged at the connection hub of the first support component 11 and the second support component 12, and is used to detect the rotation angle between the first support component 11 and the second support component 12 during joint movement to obtain angle information.

[0063] Specifically, the angle sensor 31 can use a magnetic encoder and a radial magnet; the magnetic encoder is arranged in the central area of ​​the first mounting portion 110 of the first support component 11, and the radial magnet is arranged at the corresponding position of the second mounting portion 120 of the second support component 12, and the angle information is obtained by the cooperation of the two.

[0064] Furthermore, the magnetic encoder has one or more magnetically sensitive elements similar to a "compass" integrated inside, which can sensitively detect and quantify the direction and strength of the external magnetic field, and convert these physical quantities into electrical signal outputs for easy reading and processing by an external controller.

[0065] The magnetic encoder uses the SPI interface to communicate with the controller.

[0066] Different from conventional strong magnetic neodymium magnets, the magnetic poles of radial magnets are not concentrated at the two ends of the magnet, but are distributed on the radial side of the cylinder. When the first support component and the second support component rotate relative to each other, the magnetic field generated by the radial magnet will change with the angle, which directly affects the sensing result of the magnetic encoder.

[0067] Through the cooperation between the magnetic encoder and the radial magnet, the angle information of the joint movement can be accurately obtained. Compared with traditional rotary encoders and other methods, this non-contact angle measurement method reduces the wear and life loss caused by mechanical contact and can maintain a high measurement accuracy (±0.01°) in various environments.

[0068] It should be noted that although the influence of the geomagnetic field can be ignored, strong magnetic environments should be avoided as much as possible during use to prevent external magnetic field interference from affecting the accuracy of angle measurement results.

[0069] As a preferred embodiment, the multi-sensory sensor module 3 includes: a first temperature sensor, which is fixed on the frame body 1 through a mounting bracket 13 and is used to detect ambient temperature information.

[0070] As a preferred embodiment, the multi-sensory sensing module 3 includes: a second temperature sensor, which is fixed to the frame body 1 through a mounting bracket 13, and is used to detect joint temperature information and determine whether the joint has fever or low temperature based on the joint temperature information.

[0071] Furthermore, the first temperature sensor and the second temperature sensor may adopt one infrared temperature sensor 32 to detect the ambient temperature information and the joint temperature information; or two infrared temperature sensors 32 may be provided to detect the ambient temperature information and the joint temperature information separately.

[0072] As a preferred embodiment, the multi-sensory sensing module 3 includes: a sound sensor 33, which is fixed to the frame body 1 through a mounting bracket 13 and is used to detect sound information generated during joint movement.

[0073] Specifically, the sound sensor 33 can adopt a module structure that integrates a capacitive microphone sensor and an onboard MAX9814 amplifier to accurately collect and process the sound signals accompanying the joint movement to determine whether there is an abnormal sound during the joint movement.

[0074] Furthermore, as the core element of sound collection, the capacitive microphone sensor is composed of two extremely small metal plates with a layer of insulating medium, such as carbon powder or air, between the two plates. During joint movement, the vibration of bones, soft tissues or joint capsules and the friction of airflow generated by joint movement will cause a slight change in the distance between the plates inside the microphone, thereby converting the received sound signal into a weak electrical signal.

[0075] Furthermore, considering that the initial electrical signals converted from sound signals are extremely weak and difficult to be effectively recognized and processed directly by an external controller, a high-performance MAX9814 amplifier is further integrated. This amplifier can amplify the weak electrical signals output by the capacitive microphone sensor, ensure that the signal quality is not distorted, and enhance the signal-to-noise ratio to a level sufficient for accurate reading and analysis by an external controller or other electronic equipment.

[0076] The MAX9814 amplifier can output a voltage of 0V to 5V to represent the signal amplified by the microphone sensor through the MAX9814 amplifier. The gain is the magnification, which can be controlled by three connection methods: floating, high level 5V, or low level 0V to control the amplifier's magnification to 60DB, 50DB, and 40DB respectively.

[0077] In this embodiment, the mounting bracket 13 is L-shaped, and the mounting bracket 13 can be fixedly mounted on the frame body 1. The mounting bracket 13 can also be integrally formed with the first supporting component 11 or the second supporting component 12 of the frame body 1. During the detection process, the sensor on the mounting bracket 13 is located exactly at the joint, and the sensor detection end is aligned with the joint.

[0078] Furthermore, the electrical connection between the sensor and the controller is achieved through DuPont wire to ensure the stability and reliability of data transmission.

[0079] In order to further standardize the wiring and ensure that the inside of the device is neat and orderly, multiple wire holes 104 are designed on the first support component 11 and the second support component 12. By using cable ties (such as nylon cable ties, Velcro cable ties, etc.) through these cable holes 104 to tightly fix the DuPont cables, it can not only prevent the DuPont cables from shaking inside the device and reduce the risk of electrical failures caused by cable wear, but also guide the DuPont cables to be neatly laid along the preset path, avoiding the disordered routing that affects the operating performance and appearance of the device.

[0080] Specifically, the required data is collected through sensors, including but not limited to converting physical quantities such as angle, temperature, sound, etc. into electrical signals. As a preferred embodiment, the multi-sensory sensor information includes angle information, and / or ambient temperature information, and / or joint temperature information, and / or sound information.

[0081] In this embodiment, the control module 4 can be directly fixed to the first support component 11 or the second support component 12 by hot melt adhesive, and can also be fixed to the first support component 11 or the second support component 12 by other fixing structures such as screws, snaps, embedded design, etc. to meet the needs of different application scenarios.

[0082] As a preferred embodiment, the invention further comprises:

[0083] At least one pair of first mounting holes 103 are provided through the first supporting member 11 or the second supporting member 12;

[0084] There are multiple mounting blocks 101, each of which is provided with a through hole for the mounting strip 102 to pass through. One end of each mounting block 101 is fixedly mounted to the controller housing 40 of the control module 4, and the other end of each mounting block 101 passes through the first mounting hole 103, and the mounting strip 102 passes through the two mounting blocks 101 corresponding to each pair of first mounting holes 103.

[0085] Specifically, in order to achieve a stable connection and flexible installation between the control module 4 and the main part of the joint state detection device, a first mounting hole 103, a plurality of mounting blocks 101, and a mounting strip 102 are provided in this embodiment; the first mounting hole 103 is arranged through a specific position of the first support component 11 or the second support component 12. A perforated structure for the mounting strip 102 to pass through is reserved on each mounting block. In the actual assembly process, one end of each mounting block 101 is tightly combined with the controller housing 40 of the control module 4 by a reliable fixing method, ensuring a solid connection between the control module and the support component. At the same time, the other end of each mounting block 101 just passes through the corresponding first mounting hole 103, forming an extension structure from the support component to the control module. Next, by passing the mounting strip 102 through the two corresponding mounting blocks 101 at each pair of first mounting holes 103, the locking between the mounting block and the mounting strip is ensured, so that the control module can be firmly fixed in the entire device, the connection strength between the control module and the main body of the joint state detection device is enhanced, and the installation convenience and structural stability of the device are also improved.

[0086] As a preferred embodiment, the connecting strap 2 is a Velcro strap.

[0087] Specifically, the connecting belt 2 adopts a Velcro strap design to ensure the convenience and comfort of wearing, while also being able to be flexibly adjusted to meet the needs of different users.

[0088] Furthermore, the first support component 11 or the second support component 12 is provided with a plurality of mounting positions 20 for the connecting belt 2 to be worn. The two ends of the Velcro strap are provided with a hook surface and a fleece surface respectively. By passing the hook surface portion of the connecting belt 2 through these fixing points 20 and bonding it with the fleece surface portion, the first support component 11 and the second support component 12 can be firmly bound to the user's limbs, ensuring that the joint state detection device can accurately and tightly fit around the joint, thereby effectively collecting multi-sensory sensing information during joint movement. At the same time, the adjustability of the Velcro strap also means that the device can adapt to joints of different sizes and shapes, as well as the personalized needs of different users.

[0089] As a preferred embodiment, the control module 4 is also used to perform evaluation based on multi-sensory sensing information to obtain a joint state evaluation result.

[0090] As a preferred embodiment, the invention further comprises:

[0091] A wireless module, one end of which is electrically connected to the control module, and the other end of which is remotely connected to the cloud service end, so that the control module transmits the multi-sensory sensor information to the cloud service end through the wireless module;

[0092] The cloud server is used to evaluate based on multi-sensory sensing information and obtain joint status evaluation results.

[0093] Furthermore, by comparing the multi-sensory sensing information with a preset threshold, a joint state assessment result is obtained.

[0094] In this embodiment, the preset threshold corresponding to each physical quantity can be obtained based on big data analysis, by collecting relevant physical quantity data of joints of different individuals in different environments and health states, including but not limited to multivariate information such as ambient temperature, user gender, age, health status (whether sick, severity of illness, etc.); then using advanced data analysis techniques such as statistics and machine learning, these data are deeply mined and pattern recognized, and typical threshold intervals of different physical quantities under different genders, ages, and health conditions are summarized. These intervals are preset in the control module 4 or the cloud service end, and the preset thresholds can be dynamically adjusted according to the characteristic information of different individuals, thereby realizing accurate detection and evaluation of the health of the knee joint.

[0095] In this embodiment, the preset threshold value can also be customized.

[0096] As a preferred implementation, it further includes: a detection enable button 7 , and the detection enable button 7 is electrically connected to the control module 4 .

[0097] Specifically, by setting a detection enable button 7, it is convenient for the user to start or pause the joint state detection function of the device. The button communicates with the core control module 4 through an electrical connection. The user only needs to simply press or release the button to control the start, operation or stop of the entire joint state detection system in real time.

[0098] When the user presses the detection enable button 7, the control module 4 receives a command signal to start the detection, and will start all relevant sensors to begin collecting and analyzing joint status data; conversely, when the user no longer needs to perform joint status detection, presses the button again, the control module 4 will receive an instruction to stop detection, and then command all sensors to stop working and enter the standby energy-saving state, ensuring that the device does not waste energy during non-use periods, thereby improving the practicality of the equipment and user experience.

[0099] Furthermore, the control module 4 can also preset a detection time limit. When the detection time limit is exceeded, the control module 4 directly and automatically stops the detection and saves the currently collected data. At the same time, the control module 4 prompts the user that the detection has been completed or timed out through the OLED screen or other display interface, and can also issue a sound reminder through an audio device such as a buzzer. After the detection time limit is reached, the control module 4 can automatically enter the sleep mode to save energy, and quickly wake up and restore to the working state when the next detection is enabled.

[0100] As a preferred embodiment, it further includes: a display component 6 , which is electrically connected to the control module 4 .

[0101] Specifically, the controller is used to receive electrical signals from the sensor, convert these electrical signals into data that can be understood by the computer, then pre-process and threshold the data, and output the results to a display component such as a display screen for display.

[0102] In this embodiment, Arduino Nano 42 is selected as the core controller unit. Arduino Nano has a USB interface 421. The Arduino IDE development environment is used for program writing, and the Arduino-C language is used for project development. In order to ensure the ease of use and versatility of the device, a common 9-volt direct current (9V DC) battery is selected as the power supply, and a power interface 411 is also provided on the bottom plate of the Arduino Nano expansion board 41. Considering that Arduino Nano and various sensors and displays usually require 5-volt direct current (5V DC) power supply, this embodiment integrates a low-dropout linear regulator (LDO) on the bottom plate of the Arduino Nano expansion board 41, and its function is to effectively convert the 9VDC power supply into 5VDC to meet the power supply requirements of various components of the system.

[0103] When the Arduino Nano is powered on and started, it will first perform the initialization process. At this stage, the OLED screen will be initialized and woken up, the startup prompt information will be displayed, and then each sensor will be initialized in turn. If any abnormality occurs during the initialization process, the system will display the corresponding abnormality information on the OLED screen. On the contrary, if all sensors are initialized successfully, the system will enter the "Ready to Detect" state.

[0104] In the "Ready to Detect" state, the device will continue to detect whether the user triggers a key action. Once it detects that the detection enable button 7 is pressed, the system will switch to the "Detect" state; if no key trigger is detected, the current state remains unchanged.

[0105] After entering the "detection" state, the system will continuously read and record data from various sensors, including but not limited to the joint movement angle information measured by the magnetic encoder, the ambient temperature and knee temperature data detected by the infrared temperature sensor, and the sound signal collected by the microphone sensor. At the same time, the system starts a 20-second countdown. When the countdown ends, the system exits the "detection" state and enters the "result display" state.

[0106] In the "result display" state, the system will analyze the data collected in the "detection" stage and display key results on the OLED screen, such as the maximum and minimum values ​​of the joint movement angle, the highest and lowest values ​​of the knee temperature and other important parameters, so that users can intuitively obtain accurate evaluation results of the joint status. After the results are displayed and a countdown period has passed, the system returns to the "ready to detect" state and starts a new round of detection cycle.

[0107] The device of this embodiment continuously and accurately monitors the health status of joints through closed-loop control, providing reliable data support for further professional analysis and diagnosis by doctors or related professionals.

[0108] The joint status detection device of this embodiment is suitable for monitoring the range of motion of important joints such as knee joints and elbow joints. During the detection process, physical changes such as angles, joint temperatures, and sounds emitted by bent joints under different ambient temperatures are collected and preprocessed, including but not limited to a series of processes such as filtering and weighting, and then compared with the preset thresholds of the corresponding physical quantities to obtain the health status of the joints, thereby enabling the elderly to monitor their own joint status efficiently and intelligently.

[0109] The advantages or beneficial effects of adopting the above-mentioned technical scheme are as follows: the joint status detection device of the utility model integrates multi-sensing technology, which can comprehensively monitor various physiological parameters of the joints. Through the comprehensive analysis of these diversified parameters, the accuracy of the joint health status assessment is greatly improved, and a more comprehensive and detailed rehabilitation guidance basis is provided for doctors and rehabilitation therapists; at the same time, through integrated design, multiple sensing functions are integrated into one, the operation process is simplified, and the user is more convenient during use, thereby improving the user's acceptance and satisfaction.

[0110] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
