[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0023] The following is combined with Figures 1-4 The present invention describes the dynamic control method of traction force for the cervical spine rehabilitation device, such as... Figure 1 As shown, the method includes the following steps: S110. Acquire the neck pressure acting on the cervical rehabilitation device, as well as user parameter data, which includes at least weight, height, and age. S120, Determine the basic traction force based on neck pressure; S130: Based on user parameter data, the basic traction force is corrected to determine the target traction force, and the drive motor of the cervical spine rehabilitation device is controlled based on the target traction force.

[0024] The traction dynamic control method for a cervical rehabilitation device provided by this invention obtains the neck pressure acting on the cervical rehabilitation device, as well as user parameter data reflecting the user's weight, height, and age. Based on the neck pressure, a basic traction force is determined. Based on the user parameter data, the basic traction force is corrected to determine the target traction force. Based on the target traction force, the drive motor of the cervical rehabilitation device is controlled. This enables dynamic adjustment of the traction force of the cervical rehabilitation device according to the user's actual physiological condition and actual use of the device.

[0025] The neck pressure acting on the cervical rehabilitation device is the force exerted by the user's neck on the device, which can be detected by a pressure sensor. Specifically, a high-precision pressure sensor can be integrated into the movable piece that contacts the neck in the cervical rehabilitation device to achieve real-time dynamic sensing of neck pressure. The pressure sensor includes two sensing modes: (1) Flexible curved surface adaptation mode: using an ultra-thin flexible pressure sensor to directly fit the curved surface of the movable piece; (2) Indirect force sensing mode: by constructing a pressure sensor boss structure, the mechanical load borne by the movable piece is converted into quantifiable pressure parameters of the boss contact surface.

[0026] Integrating a high-precision pressure sensor into the active pad structure enables real-time dynamic sensing and accurate measurement of neck pressure, which can improve treatment safety and avoid overload damage.

[0027] Determining neck pressure Then, the baseline traction force can be determined based on neck pressure; specifically, it is determined by multiplying the neck pressure by a preset adjustment coefficient. To obtain the basic traction force ,Right now .

[0028] Based on the baseline traction force, adjustments are made according to user parameter data to obtain the target traction force. Specifically, the user parameter data can be obtained through a data acquisition module that provides an input interface (which can be an application / mini-program / H5 page / Web page) through which the user inputs their height (…). ),weight( ),age( ).

[0029] Furthermore, to improve the matching process between target attraction and users, user parameter data can also include gender ( ),Profession( ) and history of cervical spondylosis ).

[0030] Pressure sensor detects neck pressure ( The user app (mini-program / H5 page / Web page) can display a real-time traction curve, showing the changes in neck pressure and traction progress in the form of a graph. It supports preset traction modes (such as gentle and strong), which can be selected via the app (mini-program / H5 page / Web page), and the system automatically matches the optimal parameters based on user data.

[0031] The cervical spine rehabilitation device traction dynamic control method provided by this invention can be executed by the main control board (MCU) in the cervical spine rehabilitation device. The main control board is integrated into the base and has built-in signal processing module, motor drive module, power management module, and wireless (Bluetooth / WiFi / 4G) module, etc. The pressure sensor signal is noise-reduced through a differential circuit and transmitted to the main control board for acquisition. The real-time neck pressure value received by the main control board is used to determine the target traction force through the cervical spine rehabilitation device traction dynamic control method provided by this invention. Then, the motor speed or direction is adjusted, and the cam rotation frequency (rotation amplitude and timing) is controlled to achieve adaptive adjustment of traction force. Specifically, controlling the drive motor of the cervical spine rehabilitation device based on the target traction force includes: Obtain the actual traction force fed back by the traction sensor; Adjust the speed control signal of the drive motor based on the actual traction force and the target traction force.

[0032] like Figure 4As shown, in the cervical spine rehabilitation device traction dynamic control method provided by this invention, the control of the drive motor adopts a closed-loop control algorithm, using PID (Proportion Integral Differential) regulation, comparing the target traction force with the actual traction force in real time, and dynamically adjusting the motor speed control signal (PWM). The actual traction force can be obtained through the feedback value of the traction force sensor.

[0033] Specifically, the cervical spine rehabilitation device uses a cam-driven movable plate to raise and lower, achieving traction and appropriate stretching of the cervical spine. When the movable plate is lifted by the cam, pressure is transmitted to the base through a support rod or slide bar, where a high-precision pressure sensor can be integrated to measure the traction force. A return spring is fitted onto the support rod or slide bar, located above the movable plate. When the movable plate is lifted upwards by the cam assembly, the return spring is compressed; when the cam assembly rotates to the lower movable plate, the return spring is released. This return spring can be replaced with a smart spring with a built-in strain gauge or piezoelectric ceramic to achieve actual traction force measurement.

[0034] The cervical spine rehabilitation device traction dynamic control method provided by the present invention constructs a closed-loop control system by real-time monitoring of changes in neck pressure, dynamically adjusts the motor speed or cam motion mode, and achieves adaptive and precise adjustment of traction force, avoiding the mechanical operation of massage-type traction devices that are prone to overstretching or insufficient traction.

[0035] like Figure 3 As shown, after determining the target traction force based on the collected data, the main control board controls the drive motor while simultaneously transmitting received sensor data, such as neck pressure and actual traction force, wirelessly to applications (mini-programs / H5 pages / web pages) for display, enabling real-time data visualization and interaction. For neck pressure and actual traction force, the changes in force and traction progress can be displayed as graphs, helping users intuitively track the treatment status.

[0036] In one possible implementation, data acquisition can be based on an intermittent sampling strategy. This strategy is a technique that reduces power consumption by dynamically adjusting the working / sleep cycle of sensors or modules. Its basic mechanism involves periodically waking the device to collect data, and then immediately entering a low-power sleep state after completion. Specifically, it can detect whether the cervical spine rehabilitation device has an external power supply. If so, shorter sampling intervals and sleep cycles can be used to collect neck pressure; if not, longer sampling intervals and sleep cycles can be used to collect neck pressure, thus improving the battery life of the cervical spine rehabilitation device when no external power supply is available.

[0037] The collected data on neck pressure, actual traction force, user parameters, and target traction force determined based on the collected data can be uploaded to the cloud for users to view at any time or for remote medical interaction.

[0038] The following section details the specific process for determining the target traction force.

[0039] like Figure 2 As shown, the collected data can be validated before being used to determine the target traction force. After confirming the data's validity, the target traction force can be determined based on the collected data. For ease of subsequent explanation, the variables are defined as shown in Table 1.

[0040] Table 1

[0041] To ensure user safety when using the cervical spine rehabilitation device, an upper limit for the traction force is set during the determination of the target traction force to prevent overstretching. In other words, the target traction force is determined by adjusting the baseline traction force based on user parameter data, including: Each correction coefficient is determined based on the user parameter data, and the base traction force is corrected based on the correction coefficients to determine the corrected traction force; The upper limit of traction force is determined based on the weight data in the user parameter data; The target traction force is determined based on the corrected traction force and the upper limit of traction force.

[0042] Specifically, the upper limit of traction force is 0.15g times the body weight (g is the acceleration due to gravity, taken as 9.8 N / kg). In practical applications, when detecting actual traction force, if the detected traction force exceeds the threshold of 0.15g... The machine automatically stops when the temperature reaches W and triggers an alarm via buzzer. Furthermore, for users with a severe history of cervical spondylosis, the upper limit of the traction force they can tolerate is even lower. Therefore, when the collected user parameter data indicates a severe history of cervical spondylosis (D=0.7), the upper limit threshold of the actual traction force is set from 0.15g. W changed to 0.1g W, this can effectively prevent harm to users with a history of severe cervical spondylosis.

[0043] Combining the various correction coefficients and the upper limit of traction force, the formula for calculating the target traction force can be determined as follows: , These represent the correction coefficients for weight, height, age, gender, occupation type, and history of cervical spondylosis, respectively. It's worth noting that this formula is based on user parameter data including weight, height, age, gender, occupation, and history of cervical spondylosis. If gender, occupation, and history of cervical spondylosis are missing from the user parameter data, the corresponding correction coefficient can be set to 1 to determine the target traction force.

[0044] Traction force is related to body weight, but it should be limited to a safe range to avoid excessively rapid linear increases. For taller individuals, the traction force should be adjusted to match their cervical spine length, with a slight increase in traction force. The dynamic control method for traction force in the cervical spine rehabilitation device provided by this invention determines various correction coefficients based on user parameter data, including: The weight difference value is processed by the first power operation to obtain the weight correction coefficient. The weight difference value is the ratio between the weight in the user parameter data and the preset benchmark weight. The height difference value is processed by a second power operation to obtain the height correction coefficient. The height difference value is the ratio between the height in the user parameter data and the preset benchmark height. In the first and second power operations, the power is less than 1.

[0045] Specifically, weight correction factor Where w is the baseline weight, and in one possible implementation, w can be 70kg. m is the power, and m can be 0.5 to control nonlinear effects, that is, to use the square root to weaken the influence of weight on traction force and avoid applying excessive traction force to overweight users.

[0046] Height Correction Factor Where h is the baseline height, in one possible implementation, h can be 170 and the power n can be 0.2. The power value of 0.2 can limit the correction range and balance the influence of height on cervical spine length.

[0047] For different genders, occupations, and histories of cervical spondylosis, the corresponding correction coefficients can be determined based on pre-set mapping relationships.

[0048] Specifically, gender can reflect average muscle mass, and the gender correction factor... S is set to 1.0 for males and 0.95 for females (who have lower average muscle mass).

[0049] Occupation type reflects the frequency of a user's head-down posture. For occupations involving prolonged sitting with the head down, traction needs to be enhanced to alleviate the additional load. Occupational correction coefficient. For professions where the head is frequently lowered while sitting (such as programmers), the value of O is 1.2, while for other professions it is 1.0.

[0050] Depending on the severity of the history of cervical spondylosis, the traction force needs to be adjusted to avoid injury. A correction factor based on the history of cervical spondylosis is required. When there is no history of cervical spondylosis, D is set to 1. When the severity of the history of cervical spondylosis is mild, D is set to 0.9, moderate, and severe, D is set to 0.8.

[0051] As we age, it is necessary to reduce traction intensity to protect cervical spine flexibility. Regarding the age correction factor, one possible implementation is... Where 'a' is the age baseline, which can be 30. This means that the traction force decreases by 0.8% for every additional year of age.

[0052] Substituting the individual terms into the formula for the target traction force, we get: .

[0053] Based on a practical example, the above formula is optimized as follows: User data: , , S O D , .

[0054] Adjustment coefficient based on basic traction force Perform the calculations, the calculation steps are as follows: (1) ; (2) ; (3) ; (4) ; (5) ; (6) Comprehensive calculation: ; (7) Safety constraints: .

[0055] Based on the above calculation results, the formula is optimized as follows: (1) Problem Analysis: The calculation results in the example are far from the safety threshold, so the basic traction force coefficient needs to be increased. .

[0056] (2) Adjust parameters: set ,but Final traction Still far from the safety threshold (102.9) (This needs further improvement.)

[0057] (3) Optimized formula: By introducing a nonlinear decay function, the exponential decay model is more in line with the law of physiological function degeneration, as follows: .

[0058] After adjustment: ≈0.887, traction force It is still far from the safety threshold (102.9N), and obviously the formula structure needs further adjustment.

[0059] (4) Continue to adjust parameters: reduce the dynamic adjustment base traction strength coefficient Up to 2.4, then Final traction Approaching the safety threshold (102.9) This complies with safety constraints.

[0060] (5) The final formula for calculating traction force is: .

[0061] In other words, the process of determining the age correction factor includes: Based on the difference between the age in the user parameter data and the preset baseline age, an age correction factor is determined. The age correction factor is: .

[0062] After optimization, the final formula for calculating the target traction force is as follows: .
