Technical Field

[0001] This invention relates to technologies in the fields of smart home, rehabilitation engineering, ergonomics and human-computer interaction, and in particular to an adjustable and trainable multi-scenario health swivel chair. Background Technology

[0002] Maintaining a static sitting posture for extended periods is a common cause of neck, shoulder, and lower back discomfort. While chairs with massage or rocking functions are common in current technology, their movement modes are typically limited and not well-integrated with users' daily work and entertainment activities involving computers, mobile phones, and other electronic devices. Furthermore, some rehabilitation training devices offer specialized functions but require users to interrupt their daily work for dedicated use, lacking convenience. Therefore, there is a need for a smart chair that can be better integrated into various daily use scenarios and provides gentle, passive physical movement. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an adjustable and trainable multi-scenario health swivel chair that is adjustable and trainable, improves user compliance, and simultaneously promotes spinal health and vestibular function.

[0004] In order to achieve the goal of solving the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides an adjustable and trainable multi-scenario health swivel chair, comprising a seat, armrests, base, fixed axis, rotating axis, angle sensor, drive device, control system, and control panel; wherein: The lower end of the fixed shaft is fixedly connected to the base; the base is located at the bottom and is used to support the rest of the health swivel chair; the seat is located at the upper end of the fixed shaft; the armrests are located on the left and right sides of the seat. The angle sensor includes a rotor and a stator, and is used to detect the rotation angle of the rotating shaft in real time; the rotor is connected to the rotating shaft, and the stator is connected to the fixed shaft; the angle sensor detects the angle signal of the rotor and transmits the angle signal to the control system; The drive unit includes a motor, a driving gear mounted on the motor output shaft, and a driven gear mounted on the outside of the rotating shaft; the drive unit is mounted on the fixed shaft and is used to drive the rotating shaft to rotate; the driving gear and the driven gear mesh. The control system includes a main control module, a motor drive module, an angle signal acquisition module, and a memory; the control system is installed inside the housing and is electrically connected to the drive device and the angle sensor respectively. The control panel is located on the armrest and is electrically connected to the main control module of the control system. The control panel is used to display the status of the health swivel chair and serves as an input mechanism for adjusting the parameters of the health swivel chair.

[0005] Specifically, the fixed shaft is a cylindrical structure that is vertically fixed to the center of the base; the rotating shaft is a hollow or solid column with an outer diameter smaller than the inner diameter of the fixed shaft, and is coaxially sleeved on the inner side of the fixed shaft by at least two vertically arranged rolling bearings, thereby achieving smooth and low-friction rotational support of the rotating shaft relative to the fixed shaft.

[0006] The present invention provides an adjustable and trainable multi-scenario health swivel chair, which also includes a foot pedal connected to the lower front of the seat to ensure that the foot pedal moves synchronously when the seat rotates, thereby coordinating the posture of the lower limbs and torso.

[0007] The adjustable and trainable multi-scenario health swivel chair has a control system including a main control module with a pre-installed control program. The control program is configured to control the drive device to smoothly decelerate and stop the chair, and automatically control the chair to rotate to the zero-position angle facing the user's initial sitting direction.

[0008] Specifically, the angle sensor detects the absolute rotation angle of the rotating shaft.

[0009] Specifically, the main control module of the control system is used to receive angle signals fed back by the angle sensor and setting instructions input by the user through the control panel, generate PWM control signals and direction signals according to the built-in smooth motion control algorithm, and output them to the motor drive module; at the same time, it interacts with the memory to read and write data, and calls or stores the user's personalized motion parameters. The motor drive module is used to receive PWM control signals and direction signals from the main control module, convert them into corresponding drive currents, and control the speed, direction, and start / stop of the drive motor. The angle signal acquisition module is used to acquire the A / B phase pulse signal output by the angle sensor in real time, and parse it into the current rotation angle data of the rotating shaft, and transmit it to the main control module. The memory is used for non-volatile storage of system programs, user profiles, and device operation log data.

[0010] The signal transmission and control relationship between the main control module, motor drive module, angle signal acquisition module, and memory is as follows: the angle signal acquisition module sends the parsed angle data to the main control module to form a closed-loop feedback; the main control module outputs PWM and direction control signals to the motor drive module according to the feedback signal and preset algorithm; the motor drive module drives the motor to perform the corresponding movement; at the same time, the main control module and memory perform bidirectional data read and write to save and recall user-personalized parameters; the power supply module provides the required operating voltage for other modules.

[0011] More specifically, the main control module uses a microcontroller, or MCU, as the control core.

[0012] Specifically, the control panel includes a display screen with integrated touch input function, as well as a built-in Bluetooth module and a one-button start / stop switch.

[0013] More specifically, when the one-button start / stop switch on the control panel is triggered, the control system can control the drive device to rotate the seat and stop it at the initial zero position facing the user.

[0014] Specifically, the Bluetooth module of the smart health swivel chair is used to establish a communication connection with the electronic device placed on the device bracket, so that the user can remotely control the electronic device through touch operation on the touch screen display, either by screen mirroring or by virtual control panel, without having to touch the electronic device, thus avoiding the impact on body rotation caused by hand contact with the electronic device.

[0015] Specifically, the main control module has a pre-installed control program configured to: control the motor through the motor drive module based on the angle signal fed back by the angle sensor through the angle signal acquisition module, thereby driving the seat and footrest to perform reciprocating rotational motion; and the control program uses an S-shaped velocity curve to plan the motion, so that the angular acceleration of the reciprocating rotational motion changes continuously near the start, stop and reversal points.

[0016] Specifically, after receiving the feedback signal from the angle sensor, the control system controls the drive device to drive the seat and footrest to perform horizontal reciprocating rotational motion; and the horizontal reciprocating rotational motion performs uniform deceleration when approaching the preset angle limit, and performs uniform acceleration after reversing and starting.

[0017] Specifically, the intelligent health swivel chair also includes an integrated control panel. The seat includes a left armrest and a right armrest. The integrated control panel is located on the left or right armrest of the seat and is electrically connected to the control system.

[0018] More specifically, the integrated control panel includes a display screen with integrated touch input functionality and a built-in Bluetooth module.

[0019] More specifically, the integrated control panel is equipped with a one-button start / stop switch; when the one-button start / stop switch is triggered to stop the swivel chair, the control system controls the drive device to rotate the seat and stop it at the initial zero position facing the user.

[0020] An adjustable and trainable multi-scenario health swivel chair, the control program of which further includes a personalized adaptive learning mode configured to perform the following steps: Step a. Guide the user into the calibration process and control the seat to begin reciprocating rotational movement using preset minimum intensity parameters; the minimum intensity parameters include a first angular velocity and a first unilateral rotation angle: Step b. Pause after completing this exercise cycle and prompt the user to confirm the comfort level of the current exercise intensity; Step c. If a user's comfort confirmation instruction is received, then proceed to step c.; step c includes steps c1 and c2: Step c1. Record the current motion parameters as candidate comfort parameters; Step c2. Determine whether the current strength parameter is lower than the preset strength upper limit; If the intensity is below the upper limit, the user will be prompted whether to try a higher intensity level. If a user confirms the attempt, the angular velocity or the unilateral rotation angle is increased by a predetermined step size, and the process returns to step b to move with the new parameters. If no confirmation of the attempt is received from the user, proceed to step e; If the intensity limit has been reached, proceed directly to step e; if no comfort confirmation instruction is received from the user, proceed to step d. Step d: Determine if there are any recorded candidate comfort parameters; if so, proceed to step e; if not, end the learning process and apply the system default parameters. Step e: Determine the currently recorded candidate comfort parameters as the user's personalized comfort motion parameters and save them to the memory of the control system.

[0021] Specifically, the adjustable and trainable multi-scenario health swivel chair includes a Bluetooth module used to establish a wireless connection with external electronic devices. Specifically, the control program is further configured to: display a virtual control interface on the touch screen in interconnected mode, and send the user's touch operation commands on the virtual control interface to the external electronic device via the Bluetooth module to achieve remote control.

[0022] Specifically, the adjustable and trainable multi-scenario health swivel chair has an angular velocity range of 1° / s to 6° / s for its horizontal reciprocating rotational motion.

[0023] Specifically, the adjustable and trainable multi-scenario health swivel chair has a single-sided rotation angle range of 5° to 60° for the horizontal reciprocating rotational motion.

[0024] These technical solutions can also be combined or integrated to achieve better technical results.

[0025] By adopting the above technical solution, the adjustable and trainable multi-scenario health swivel chair of the present invention has the following beneficial effects: Smooth and comfortable motion: Thanks to the technical feature of "smooth reciprocating rotation based on angle sensor feedback control drive device", the control system ensures continuous acceleration changes during motion start-up, stopping and reversal through precise closed-loop control and S-shaped speed planning, effectively avoiding the discomfort caused by sudden speed changes.

[0026] Convenient and integrated operation: Thanks to the adoption of a control panel with an integrated touch screen and Bluetooth module and the technology of "remotely controlling electronic devices via touch screen", users can centrally complete exercise settings, status checks, and remote basic control of devices such as mobile phones and tablets from the seat, such as touch control and media playback control, which improves the convenience and immersion of use in entertainment and light office scenarios.

[0027] Adapting to individual needs: Thanks to the technical feature of the "personalized adaptive learning mode", the device can guide users to experience and confirm multiple intensity levels, automatically record and match the movement speed and angle parameters that they feel comfortable with, thereby adapting to the differences in physical sensations of different users.

[0028] Functional and scenario-based: Thanks to the adoption of the "one-button start / stop and automatic return to zero position" technology, users can quickly pause their exercise and return the seat to the angle facing the workbench at any time while working, realizing a quick and seamless switch between health activities and focused work scenarios.

[0034] The present patent will be further explained and described below with reference to the accompanying drawings and embodiments. However, the scope of protection of this patent is not limited to the specific implementation methods. Example 1

[0035] As attached Figure 1 , Figure 2 As shown, the mechanical body of an adjustable and trainable multi-scenario health swivel chair according to the present invention includes: Base 6: Provides stable support for the entire device.

[0036] Fixed shaft 5: Its lower end is vertically fixed to the center of the base 6.

[0037] Rotating shaft 4: It is sleeved inside the fixed shaft 5 and can rotate horizontally relative to the fixed shaft 5.

[0038] Seat 1 and footrest 15: Seat 1 is fixedly mounted on the top of rotating shaft 4. Footrest 15 is connected to the bottom of seat 1 by screws to ensure that when seat 1 rotates, footrest 15 can move synchronously, so as to coordinate the posture of the lower limbs and torso.

[0039] The drive unit includes a motor 7 mounted on the outside of the fixed shaft 5, a drive gear 8 fixed on the output shaft of the motor, and a driven gear 9 fixed on the outside of the rotating shaft 4. The drive gear 8 and the driven gear 9 mesh with each other to transmit the rotational motion of the motor 7 to the rotating shaft 4.

[0040] Angle sensor 10: Its rotor part is connected to the rotating shaft 4, and its stator part is connected to the fixed shaft 5. It is used to detect the absolute or relative rotation angle of the rotating shaft 4 in real time and output the angle signal.

[0041] Housing 16: Covered above the base 6, used to house and protect internal components such as motor 7, drive gear 8, driven gear 9, angle sensor 10, control circuit board 11, and power module 12.

[0042] Control panel 3: Installed on armrest 2, its hardware includes a capacitive touch screen 19, a Bluetooth 4.0 or higher communication module 20, a physical one-touch start / stop switch 21, and several auxiliary function buttons 22. All cables 14 are concealed.

[0043] like Figure 3 As shown, the control system specifically includes the following functional modules in hardware: Main control module: A microcontroller, i.e., MCU, is used as the control core.

[0044] Motor drive module: Employs an H-bridge motor drive chip, receiving PWM and direction signals from the main control module to drive motor 7 in both forward and reverse directions. PWM signal stands for Pulse Width Modulation signal.

[0045] Angle signal acquisition module: used to read the A / B phase pulse signal output by angle sensor 10 and convert it into an angle value for the main control module to read.

[0046] Touchscreen driver module: Used to drive the touchscreen display 19 and process user touch input events.

[0047] Bluetooth module 20: Used to establish a wireless connection with external electronic devices 18.

[0048] Memory: Uses EEPROM or Flash chip to store user-set parameters, personalized learning files and system programs.

[0049] Power management module: namely power module 12, which converts the externally input 220V AC power or the DC power of the built-in battery into the operating voltage required by each module.

[0050] The signal connection relationships between the modules are as follows: the angle sensor 10 is connected to the angle signal acquisition module; the display screen 19, Bluetooth module 20, and one-button start / stop switch 21 are respectively connected to the corresponding interfaces of the main control module; the main control module controls the motor 7 to move through the motor drive module according to the program logic; the operating parameters are stored in the memory.

[0051] Specific implementation of the smooth motion algorithm: To achieve the function of "continuous velocity change near the reversal point", this invention uses an S-curve, or S-shaped velocity curve, for motion planning. Specifically, the angular acceleration of rotation is planned during the motion start-up, stopping, and reversal phases.

[0052] Definition: Let the target angular velocity be ω, ranging from 1° / s to 6° / s; the one-way rotation angle be θ, ranging from 5° to 60°; and the angular acceleration change time be t_acc.

[0053] Startup phase: Angular acceleration α starts from 0, increases linearly to its maximum value α_max (e.g., 1.5 rad / s²) within a time interval t_acc / 2, and then decreases linearly to 0 within a time interval t_acc / 2. During this process, angular velocity ω smoothly increases from 0 to a set value.

[0054] During the uniform velocity phase: the angular acceleration remains at 0, and the angular velocity remains at the set value ω.

[0055] Stop / Reversal Phase: When the angle sensor 10 detects that the seat is approaching the preset angle boundary value, i.e., θ or -θ, the deceleration phase begins. The angular acceleration α changes linearly from 0 to -α_max, and then back to 0, causing the angular velocity to smoothly decrease to 0. If it is a reciprocating motion, after the velocity drops to 0, it immediately accelerates in the opposite direction with a symmetrical S-shaped curve.

[0056] Throughout the entire motion process, the main control module adjusts the PWM output in a closed loop based on the real-time angle feedback from the angle sensor 10, ensuring that the actual motion trajectory closely follows the planned curve.

[0057] Specific implementation of personalized adaptive learning model: This mode aims to help users determine their preferred speed and angle of motion. The specific steps are as follows: Instructions begin: The user selects "Learning Mode" via display screen 19, and the screen prompts the user to sit up straight and look at a fixed point in front of them.

[0058] Start learning: The system controls seat 1 to start moving with the lowest parameters: angular velocity ω1 = 1° / s, rotation angle θ1 = ±10°, and performs 3-5 cycles of reciprocating motion.

[0059] Inquiry and Adjustment: After the exercise is paused, the display screen 19 shows the prompt: "Is the current intensity comfortable?", and provides two options: "Yes / Comfortable" and "No / Uncomfortable".

[0060] If the user clicks "Yes / Comfortable", they will be redirected directly to the parameter saving page.

[0061] If the user clicks "No / Uncomfortable," the system will enter the parameter adjustment interface. The user can manually adjust the speed or angle value within the allowable range (e.g., speed: 0.5° / s ~ 6° / s, angle: 5° ~ 60°) using the "+" / "-" buttons on display 19. After the user confirms the new parameters, the system will perform 3-5 cycles of reciprocating motion according to the new parameters and repeat the prompts in this step.

[0062] Parameter saving: The system binds the speed value ω_user and angle value θ_user, confirmed by the user's last click of "Yes / Comfort," to the user's identity and saves them to the storage as the user's "personalized comfort profile." These profile parameters can be directly accessed in daily mode.

[0063] Implementation of multi-scenario functional logic: Basic scenario: Call user profile parameters or default parameters to continuously perform smooth motion control loop.

[0064] Work scenario: Applicable to scenarios where computers are used. For example... Figure 5 As shown, when the user is looking at the screen, the smooth motion control cycle is invoked. When the user is using the keyboard and mouse, the one-button start / stop switch 21 can be pressed, and the seat 1 will immediately and smoothly decelerate to a stop and automatically rotate back to the "zero position" facing forward.

[0065] Entertainment Scenarios: Suitable for watching videos, reading e-books, and other entertainment activities. A smooth motion control loop is invoked, and the control system successfully pairs with a mobile phone or electronic device 18, such as a tablet, placed on the device holder 17 via Bluetooth module 20. A simulated touchpad interface or media control interface can be displayed on the screen 19. Users can remotely control the electronic device 18 by swiping and tapping on the screen 19, such as swiping the screen, tapping play / pause, adjusting the volume, etc.

[0066] Safety and Expansion: The device features a one-button start / stop switch as an emergency interruption method. The power module 12 can be powered by an external AC adapter or a built-in lithium battery.

Its output A / B phase pulse signal is first transmitted to the encoder signal acquisition module, processed and converted into an angle digital signal, and then transmitted to the main control module.

[0069] One-button start / stop switch 21: Located on the control panel 3 on the handrail, it sends a switch signal directly to the main control module for emergency pause or return to center operation.

[0072] 4. Energy and Execution Units: Power module 12: Provides operating voltage for the entire system. Its output VCC / GND is connected to the main control module, motor drive module, touch screen and Bluetooth module respectively.

[0073] Motor drive module: The motor drive module, also known as the H-bridge, receives the PWM / direction signal from the main control module, converts it into the corresponding drive current, and outputs it to the motor 7, thereby controlling the speed, direction, and start / stop of the motor 7.

[0074] 5. External equipment: External electronic device 18, such as a mobile phone or tablet computer, wirelessly exchanges data with Bluetooth module 20 via Bluetooth radio frequency signals. Users can remotely operate the external electronic device 18 through a virtual control interface on the integrated touchscreen display 19.

Based on the user's comfort level, the speed or angle value is manually adjusted until a suitable level of comfort is achieved, then confirmed as the new parameters and saved in memory.
