Description

Technical Field

[0001] This invention relates to the field of physiotherapy devices, specifically to an AI magnetic therapy device and glasses. Background Technology

[0002] Magnetotherapy, as a physical therapy method, works by applying changing magnetic fields to acupoints or affected areas of the body. Through electromagnetic induction, it promotes local blood circulation and improves cell metabolism, thereby achieving health maintenance and adjunctive treatment. This technology has been widely applied in rehabilitation medicine, traditional Chinese medicine physiotherapy, and daily health care.

[0003] In existing technologies, magnetic therapy devices typically generate alternating magnetic fields by rotating permanent magnets. Specifically, these devices generally mount a permanent magnet assembly on a rotating mechanism, and a drive unit continuously rotates the permanent magnet, causing the direction of its magnetic field to change periodically relative to the treatment area, thus creating an alternating magnetic field environment. This method has a relatively simple structure and allows for adjustment of the magnetic field strength and frequency.

[0004] However, in terms of driving method, existing magnetic therapy devices generally use electromagnetic motors (such as DC motors, stepper motors, etc.) as the rotational power source. When the motor is running, its internal excitation coil generates a strong stray magnetic field, and this magnetic field fluctuates dynamically with changes in armature current. This motor magnetic field is difficult to completely isolate from the working magnetic field of magnetic therapy in space, which easily leads to magnetic field superposition and coupling interference. This results in waveform distortion and unstable intensity of the magnetic field acting on the human body, affecting the accuracy and repeatability of the magnetic therapy effect. Summary of the Invention

[0005] Based on this, it is necessary to address the above-mentioned problems. The present invention provides an AI magnetic therapy device, comprising: an ultrasonic motor having a stator and a rotor; a magnetic core support fixedly connected to the rotor; a magnetic core having a central axis, rotatably mounted on the magnetic core support about the central axis; a first bevel gear fixedly connected to the magnetic core; and an upper cover assembly including an upper cover and a second bevel gear fixedly mounted within the upper cover, the upper cover being fixedly connected to the stator, the first bevel gear and the second bevel gear meshing with each other; the ultrasonic motor can drive the magnetic core to rotate simultaneously about the central axis and an orthogonal axis orthogonal to the central axis.

[0006] According to one embodiment of the present invention, the magnetic core support is an annular support, which is fixedly disposed inside the rotor.

[0007] According to one embodiment of the present invention, the magnetic core support has two radially opposite connecting holes and also includes a magnetic core shaft. The first bevel gear and the magnetic core are sequentially fixedly sleeved on the magnetic core shaft, and the two ends of the magnetic core shaft are rotatably disposed in the connecting holes.

[0008] According to one embodiment of the present invention, the magnetic core support has two radially opposite connecting holes, the first bevel gear is fixedly connected to the outer periphery of the magnetic core, and the magnetic core has connecting protrusions at both ends, the connecting protrusions being rotatably disposed in the connecting holes.

[0009] According to one embodiment of the present invention, the magnetic core support has two radially opposite connecting holes. One side of the first bevel gear is fixedly connected to one end face of the magnetic core, and the other side has a bevel gear protrusion. The side of the magnetic core away from the first bevel gear has a connecting protrusion. The bevel gear protrusion and the connecting protrusion are respectively rotatably disposed in the connecting holes.

[0010] According to one embodiment of the present invention, the system further includes a base, the stator is fixedly disposed on the base, and the upper cover is fixedly disposed on the base.

[0011] According to one embodiment of the present invention, the magnetic core has a circular cross-section and includes a plurality of fan-shaped magnetic core units along the circumferential direction, wherein the magnetic poles of two adjacent magnetic core units located at the radially outer ends of the magnetic core are opposite.

[0012] According to one embodiment of the present invention, at least one of the magnetic core units has a gradient magnetic field along the radial direction of the magnetic core.

[0013] According to one embodiment of the invention, the top cover and / or base constitute at least a portion of the housing of eyeglasses, headband, or handheld device.

[0014] The present invention also provides a pair of glasses, including temples, wherein the aforementioned AI magnetic therapy device is disposed within the temples.

[0015] The beneficial effects that this invention can achieve are as follows: 1. Fewer transmission links and more precise control. This invention uses a miniature ultrasonic motor directly connected to the magnetic core support to directly drive the magnetic core to rotate around the orthogonal axis bb. There is no need for intermediate gears or other transmission components, resulting in fast motion response and high control precision.

[0016] 2. Low noise and miniaturization. The miniature ultrasonic motor used in this application has low noise and adopts a direct drive magnetic core support method, which eliminates the intermediate transmission link, effectively reducing the noise caused by transmission, saving space, making the overall structure more compact, and easy to miniaturize.

[0017] 3. No magnetic field interference. The miniature ultrasonic motor used in this application is driven by the piezoelectric effect and generates no electromagnetic field during use. This will not interfere with the magnetic field generated by the magnetic core, thus ensuring the stability of the magnetic field.

[0018] 4. Diverse magnetic field configurations. The magnetic core in this application adopts a multi-magnetic-zone magnetization method, which makes the magnetic core generate more complex and varied magnetic field patterns when rotating, thereby enhancing the magnetic therapy effect.

[0019] 5. Wide applicability.

The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] See Figure 1-3 As shown, this embodiment of the AI ​​magnetic therapy device 100 includes an ultrasonic motor 20, which has a stator 22 and a rotor 21. When energized, the stator 22 drives the rotor 21 to rotate. A magnetic core support 30 is fixedly connected to the rotor 21. When the rotor 21 rotates, it drives the magnetic core support 30 to rotate as well. The magnetic core 50 is a cylindrical structure with magnetism and a central axis aa, which is its rotation axis. The magnetic core 50 is rotatably mounted on the magnetic core support 30 about the central axis aa, so that the magnetic core 50 can rotate relative to the magnetic core support 30 around the central axis aa. A first bevel gear 40 is fixedly connected to the magnetic core 50. When the magnetic core 50 rotates, the first bevel gear 40 will follow it and rotate relative to the magnetic core support 30 around the central axis aa. In addition, the AI ​​magnetic therapy device 100 also includes a base 10 and a top cover assembly 70, which together serve as an external shell to support the ultrasonic motor 20, magnetic core 30, and other structural components. Specifically, the stator 22 of the ultrasonic motor 20 is fixedly mounted on the base 10, thereby fixing and supporting the ultrasonic motor 20 on the base 10. The upper cover assembly 70 is fixedly mounted on the base 10 and located at the upper end of the ultrasonic motor 20, so that the ultrasonic motor 20 is housed in the receiving cavity formed by the base 10 and the upper cover assembly 70.

[0025] See Figure 4 As shown, the upper cover assembly 70 includes an upper cover 71 and a second bevel gear 72 disposed inside the upper cover 71. In this embodiment, the upper cover 71 is a cylindrical structure with an opening at one end, and the second bevel gear 72 is fixedly disposed on the top wall of the upper cover 71, and the second bevel gear 72 is concentrically disposed with the upper cover 71.

[0026] See Figure 1-5As shown, when the ultrasonic motor 20 is housed in the receiving space formed by the upper cover 71 and the base 10, the first bevel gear 40 and the second bevel gear 72 mesh with each other. Driven by the ultrasonic motor 20, on the one hand, the ultrasonic motor 20 drives the magnetic core support 30 to rotate around the orthogonal axis bb, which is orthogonal to the central axis aa, thereby driving the magnetic core 50 to rotate (revolve) around the orthogonal axis bb along with the magnetic core support 30; on the other hand, since the magnetic core 50 is rotatably mounted on the magnetic core support 30, while the magnetic core 50 rotates around the orthogonal axis bb, the first bevel gear 40 and the second bevel gear 72 mesh with each other, and under the drive of this bevel gear assembly, the magnetic core 50 will rotate (rotate) relative to the magnetic core support 30 around its own central axis aa. Therefore, in this embodiment, the ultrasonic motor 20 can drive the magnetic core 50 to rotate simultaneously around the central axis aa and the orthogonal axis bb, which is orthogonal to the central axis aa.

[0027] The miniaturized ultrasonic motor 20 in this embodiment is driven by piezoelectric ceramics and has motor leads 221 on the stator for electrical connection to the power supply and control system. This ultrasonic motor 20 is free of electromagnetic interference and features high torque and low noise. During operation, the ultrasonic motor drives the magnetic core 50 to revolve around the orthogonal axis bb at a relatively high speed (e.g., several hundred revolutions per minute), while simultaneously, through a bevel gear pair (composed of a first bevel gear and a second bevel gear), the magnetic core 50 rotates around the central axis aa at a lower speed (e.g., several revolutions per minute). The superposition of these two rotational motions causes the magnetic field generated by the magnetic core 50 to change frequently in three-dimensional space, effectively promoting blood circulation when applied to acupoints. Because this application uses a miniature ultrasonic motor for direct drive, the transmission link is only a single-stage bevel gear, resulting in a compact overall structure, low noise, and no magnetic field interference, ensuring the purity and stability of the magnetic field used in magnetic therapy.

[0028] See also Figure 1-2 As shown, in this embodiment, the magnetic core support 30 is an annular support, fixedly installed inside the rotor 21. Two radially opposite connecting holes 31 are provided on the magnetic core support 30. The connecting holes 31 can be configured as through holes, countersunk holes, or stepped holes. The first bevel gear 40 and the magnetic core 50 are sequentially fixedly sleeved on the magnetic core shaft 60, that is, the magnetic core shaft 60 passes through the magnetic core 50 and the first bevel gear 40 sequentially and is fixedly connected to them. The two ends of the magnetic core shaft 60 are exposed outside the first bevel gear 40 and the magnetic core 50, respectively, and are rotatably installed in the connecting holes 31 on both sides, thereby achieving a rotatable connection between the magnetic core 50, the first bevel gear 40, and the magnetic core shaft 60 as a whole with the magnetic core support 30. When the magnetic core support 30 rotates around the orthogonal axis bb, the first bevel gear 40 drives the magnetic core shaft 60 to rotate, thereby achieving the rotation of the magnetic core 50 around its own central axis aa.

[0029] In other embodiments, the magnetic core shaft may be omitted. In this case, the first bevel gear is fixedly connected to the outer periphery of the magnetic core. The two can be manufactured separately and then fixedly connected, or they can be directly integrally formed. In this case, both ends of the magnetic core have connecting protrusions, which are rotatably disposed in the connecting holes, thus achieving a rotatable connection between the magnetic core and the magnetic core support. Alternatively, the first bevel gear can be disposed at one end of the magnetic core. In this case, one side of the first bevel gear is fixedly connected to one end face of the magnetic core, and the other side has a bevel gear protrusion. The side of the magnetic core away from the first bevel gear has a connecting protrusion, and the bevel gear protrusion and the connecting protrusion are rotatably disposed in the connecting holes.

[0030] In this embodiment, the top cover 71 and / or the base 10 can form at least part of the glasses, headband, or handheld housing, thereby embedding the AI ​​magnetic therapy device into the glasses, headband, or handheld housing.

[0031] See Figure 6 As shown, the magnetic core 50 has a circular cross-section and includes multiple fan-shaped magnetic core units 51 along the circumferential direction. The magnetic poles of two adjacent magnetic core units 51 located at their radially outer ends are opposite. Therefore, for each magnetic core unit 51, the magnetic poles at its radially outer end (i.e., on the outer circumferential side) are opposite to those of the adjacent magnetic core unit 51, resulting in the magnetic poles on the outer circumferential side of the magnetic core unit 51 being arranged alternately from N to S.

[0032] In other embodiments, for some or all of the magnetic core units 51, there is a gradient magnetic field in the radial direction of the magnetic core, that is, the magnetic field strength of the magnetic core unit 51 increases or decreases from the center of the magnetic core outwards.

[0033] In this embodiment, by setting multiple magnetic core units with opposite magnetic levels and making the magnetic core units have gradient magnetic fields, the magnetic core can generate rich magnetic field configurations during rotation. The magnetization of multiple magnetic regions further enhances the complexity and range of the magnetic field.

[0034] See Figure 7 As shown, this embodiment also relates to a pair of glasses 200, which has lenses 210 and temples 220, with the AI ​​magnetic therapy device 100 embedded in the left and right temples 220. To enable the AI ​​magnetic therapy device 100 to operate normally, a battery 110 and a controller 300 are also embedded in the temples 220. The battery 110 supplies power to the AI ​​magnetic therapy device 110 and the controller 300, while the controller 300 controls the ultrasonic motor 20, thereby controlling the rotation of the magnetic core 50 to achieve different types of magnetic field output.

[0035] The ultrasonic motor (USM) 20 in this application is a novel drive device that utilizes the inverse piezoelectric effect of piezoelectric materials to convert electrical energy into mechanical energy through ultrasonic vibration. It differs fundamentally from traditional electromagnetic motors; it has no windings or magnetic circuits, does not rely on electromagnetic force to transmit energy, and typically operates in the ultrasonic frequency domain above 20kHz. The rotational speed of the rotor 21 relative to the stator 22 of the ultrasonic motor 20 is proportional to the vibration frequency of the stator. The operating parameters of the ultrasonic motor can be adjusted by the controller 300 to control its rotational speed, output torque, and forward / reverse rotation. These operating parameters include the stator's drive frequency, phase difference (forward / reverse rotation is achieved by leading / lagging by 90°), vibration amplitude (by adjusting the voltage applied to the piezoelectric material), and duty cycle (by adjusting the pulse width). A camera (not shown in the figure) is mounted on the upper part of the glasses 200. This camera can be mounted on the temple 200 or the frame to capture the user's eye movements. In this embodiment, eye movements include opening, closing, and blinking. The controller 300 receives input signals from the camera and identifies eye activity states. These eye activity states include the duration of the user's eyes being open, the duration of their eyes being closed, and the frequency of blinking.

[0036] Considering that traditional magnetic therapy devices are usually handheld or wearable devices, users need to manually adjust them or operate them according to the device's preset program, which limits their convenience and targeted use.

[0037] This embodiment provides an AI-powered smart magnetic therapy glasses that automatically adjusts the magnetic field strength based on the user's blinking activity, as well as a control method for the glasses. By capturing the user's eye movements through a built-in camera and combining this with intelligent algorithms (such as image recognition and motion detection), the system analyzes and identifies the user's eye activity state, thereby determining the user's current health status and magnetic therapy needs. The system then intelligently adjusts the parameters of the ultrasonic motor, thereby adjusting the output magnetic field of the magnetic core to achieve a more personalized magnetic therapy effect and improve the accuracy and comfort of the treatment.

[0038] Specifically, the control method for these glasses includes the following steps: A camera mounted on the glasses captures the user's eye movements. The controller receives the camera signals and identifies the user's eye activity state, including the duration of eye opening, eye closing, and blinking frequency. Based on this eye activity state, the controller adjusts the operating parameters of the ultrasonic motor, thereby adjusting the output magnetic field of the magnetic core. For example, if the controller detects that the user's eyes are closed for more than 20 seconds, it determines that the user is resting with their eyes closed. In this case, the controller automatically reduces the speed of the ultrasonic motor or turns it off to reduce noise and minimize the impact of the AI ​​magnetic therapy device on the user's rest. If the controller detects that the user's blinking frequency exceeds 20 times per minute, it determines that the user is experiencing anxiety or poor health. In this case, the ultrasonic motor speed can be increased to enhance the massage effect.

[0039] Specifically, this embodiment provides a smart magnetic therapy glasses and its control method that can automatically adjust magnetic field therapy parameters according to the user's eye activity state. The core of this method lies in establishing a closed-loop mapping and control model from eye physiological signals to magnetic field output parameters, thereby achieving personalized and adaptive treatment.

[0040] The first step is eye movement quantification and state recognition. The system uses a miniature camera to capture real-time images of the user's eyes, and after image processing, extracts three key quantitative parameters: degree of eye opening. Defined as the current distance between the upper and lower eyelids. Spacing with user calibration reference The ratio, i.e. This parameter is dimensionless, ranging from 0 to 1, and reflects the degree of eye opening. Eye-closing duration. The unit is seconds (s), referring to the continuous satisfaction of... Cumulative time of the conditions. Blink frequency. The unit is blinks per minute (blinks / min), which counts the number of blinks completed per minute.

[0041] Based on the above parameters, the controller divides the user state into four discrete operating modes. The mathematical logic for this division is: if... If it enters sleep mode, then it will enter sleep mode; otherwise, if If it blinks frequently, then it enters a high-frequency blinking mode; otherwise, if... If the eye is closed, it enters the relaxation mode; otherwise, it enters the normal mode.

[0042] The second step is to set the target magnetic field strength based on the state. The system calculates the target magnetic flux density according to the identified operating mode. The unit is millitalas (mT). Its calculation formula is a piecewise function:

[0043] in, Threshold for judging sleep with eyes closed. Based on the therapeutic magnetic induction intensity, The magnetic field enhancement coefficient is a dimensionless constant between 0 and 1, used to control the adjustment intensity. This represents the actual blinking frequency (times / min). This is the baseline value for normal blinking frequency. This is the upper limit for adjusting blink frequency. Threshold for determining high-frequency blinking, To measure the degree of eye opening (dimensionless). The threshold for judging with eyes closed.

[0044] The third step is the conversion of magnetic field strength into driving current. The target magnetic field needs to be achieved by driving the magnetic core with current. The magnetic induction intensity generated by the magnetic core in this system... With drive current The relationship can be equivalent to the Helmholtz coil model, and its mathematical expression is: , Therefore, based on the target magnetic field strength Calculate the target drive current (Unit: Ampere, A):

[0045] in, is the magnetic circuit correction coefficient, which is a dimensionless constant (0.65 in this embodiment) used to compensate for the difference between the actual magnetic core structure and the ideal Helmholtz coil model. It is obtained through experimental calibration. is the vacuum permeability, and is a physical constant. The equivalent number of coil turns is a dimensionless integer representing the equivalent magnetization capability of the magnetic core. The radius is the equivalent coil radius.

[0046] The fourth step is closed-loop current control based on incremental PID. The system detects the actual drive current through a Hall current sensor. ,in Representing the One control cycle. The controller uses an incremental digital PID algorithm to calculate the control quantity (SPWM modulation). Adjustment amount This is to achieve precise current tracking. The control algorithm is as follows: , , in, For the first Current error (A) per control cycle. This is the target current value. These are the proportional, integral, and derivative gains, respectively, which are dimensionless control parameters tuned according to the system characteristics. This is the sampling period of the control system. For the first The incremental adjustment of the SPWM modulation degree per control cycle. The new modulation degree is... Updated SPWM modulation This directly determines the amplitude of the driving voltage applied to the ultrasonic motor, thereby controlling its speed and the rotational motion of the magnetic core, ultimately achieving closed-loop regulation of the magnetic field strength.

[0047] Step 5: Mode Characteristics and Safety Protection. In normal mode, the system maintains stable basic treatment. In high-frequency blinking mode, the magnetic field strength dynamically increases within the range of 1.5mT to 3.0mT according to a formula, with a smooth increase process and a response time of less than 2 seconds. In closed-eye relaxation mode, the magnetic field strength varies with... The magnetic field strength decreases linearly. After entering sleep mode, the system smoothly reduces the magnetic field strength to zero within 5 seconds, then shuts down most of the circuitry to enter a low-power state. The entire control process incorporates multiple safety protection mechanisms, including strict limits on maximum current (3A), maximum temperature (45℃), and magnetic field change rate (0.5 mT / s), ensuring the safety and comfort of the treatment. Through the aforementioned complete mathematical modeling and control process, this embodiment achieves intelligent, adaptive closed-loop control of the magnetic therapy glasses from physiological signal perception to physical field output, enabling the treatment to respond in real time to the user's physiological and mental state, thus improving treatment effectiveness and user experience.

[0048] Regarding the eye movements used, on the one hand, these eye movements can be unconscious eye movements by the user, which can reflect the user's psychological or physiological state to a certain extent. This allows the controller to adapt to the user's current magnetic therapy needs and ensure the best magnetic therapy effect of the magnetic core's output magnetic field. On the other hand, these eye movements can also be conscious eye movements by the user. For example, when the user wants to turn off the AI ​​magnetic therapy device, they can actively close their eyes for a period of time, thereby causing the controller to turn off the ultrasonic motor.

[0049] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. The scope of protection of this patent should be defined by the appended claims.
