Description

Technical Field

[0001] This invention relates to the field of smart diving watches, specifically to a multi-dimensional composite input control method and a smart watch using this method. Background Technology

[0002] Current smartwatches generally use touchscreens as the primary interaction method, supplemented by buttons or rotary input structures for interface switching and function control. However, when these devices are used in diving environments, due to factors such as the conductivity of water, screen wetness, wearer wearing gloves, and external water pressure, traditional touch input methods suffer from problems such as low recognition rate, high probability of accidental touches, lack of directionality, and difficulty in performing confirmation operations, making it difficult to meet the operational needs of diving scenarios.

[0003] To reduce accidental touches, some diving watches use physical buttons instead of touch input. However, the number of buttons is limited and the input dimensions are low, only enabling simple operations such as one-way page turning or single-step switching. They cannot support complex interactions such as multi-level menus, mode switching, or numerical adjustments. In addition, physical buttons are susceptible to changes in button travel due to water pressure variations in deep water environments, and deep-sea gloves further reduce the sensitivity of button activation.

[0004] Some devices have also attempted to use a rotating ring structure for input, but this type of structure usually only outputs non-directional pulse signals, requiring additional Hall sensors, angle encoders or magnetic sensing modules to identify directionality, increasing cost and complexity, and still making it difficult to execute confirmation or locking commands.

[0005] In summary, existing technologies still lack an interaction method that can achieve low false touches, direction determination, dwell confirmation, and mode switching in a diving environment without the need for complex sensor structures. In particular, there is a lack of a control method that combines rotary input, touch input, and dwell signals to achieve multi-dimensional interaction. Summary of the Invention

[0006] According to embodiments of the present invention, a multi-dimensional composite input control method and a smartwatch using the method are provided. This addresses the technical problems existing in the background art described above.

[0007] In a first aspect of the present invention, a multidimensional composite input control method and a smartwatch using the method are provided.

[0008] The multidimensional composite input control method includes the following steps: S1. Monitor the pulse signal generated by the first input source in real time, and monitor the trigger status of the second and third input sources; S2. Perform time-domain analysis on the pulse signal of the first input source: if the duration of the pulse signal at the effective level is less than a preset time threshold, it is configured as a step signal; If the duration of the pulse signal at the effective level is greater than or equal to the time threshold, it is configured as a dwell signal; S3. Based on the states of the second input source and the third input source, perform first-level processing on the step signal to generate a directional adjustment command; S4. Generate a state switching instruction based on the combination state of the dwell signal and the second input source or the third input source.

[0009] Preferably, the first-level processing in step S3 specifically includes: when the second input source is detected to be in a triggered state and the step signal is received at the same time, the adjustment command is defined as a positive increment or page up; When the third input source is detected to be in a triggered state and the step signal is received at the same time, the adjustment command is defined as reverse decrement or page down. When the second input source is not detected or the third input source is not triggered, the adjustment command is defined as a one-way cyclic switching.

[0010] Preferably, in the locked state, a single step signal, dwell signal, or single touch signal will not trigger a state switch. The unlocking process is as follows: First, the dwell signal is triggered by a rotation operation. During the period of maintaining the dwell signal, if the second input source is detected to be triggered, an unlocking command or a confirmation entry command is generated.

[0011] Preferably, whenever the pulse signal of the first input source is detected to have a level transition and enter an effective state, the vibration unit is immediately driven to generate a short navigation vibration to indicate to the user that the user is currently in a dwelling position; If the pulse signal remains unchanged within a preset window period after the navigation vibration is generated, the timer is automatically accumulated to trigger the dwell signal.

[0012] Preferably, the method is further configured to: during the process of determining the dwell signal, if high-frequency jitter of the pulse signal is detected between the effective level and the ineffective level, calculate the duty cycle of the pulse signal; If the duty cycle is higher than the preset value, the system will forcibly determine that the first input source is still in a valid contact state and maintain the operation of the timer until a clear displacement signal is detected.

[0013] Preferably, the monitoring of the second input source and the third input source is configured such that the system reads the background conductivity between the two input sources in real time and establishes a dynamic reference value; Only when the rate of change of the detected electrical signal exceeds the mutation threshold set based on the dynamic reference value is it confirmed as a valid human touch trigger, so as to filter out false touch signals caused by the conductivity of water.

[0014] Preferably, when the first input source is detected to continuously generate more than a preset number of step signals within a preset time period, and no dwell signal or trigger signal from the second or third input source is detected during this period, it is determined to be an abnormal operation by the user, and the system automatically triggers the highlight distress mode or resets to the safe default settings.

[0015] In a second aspect of the invention, a smartwatch is provided.

[0016] Includes the base assembly, touch unit, drive ring, and transmission unit; The touch unit includes a touch screen and a housing; The bottom shell assembly is connected to the outer shell, and the drive ring is disposed on the outside of the outer shell and rotatably connected to the outer shell; The drive ring is used to trigger the transmission unit; The bottom shell assembly includes a protective shell, a first contact terminal, a second contact terminal, and a circuit board; The circuit board is connected to the protective shell, and both the first contact end and the second contact end are connected to the circuit board and are disposed on the side wall of the protective shell.

[0017] Preferably, a gear ring is provided below the drive ring, and the transmission unit includes a first gear, a first housing, a first bracket, a wheel, a spring, a snap-fit ​​part, an extension part, and a contact switch; The first gear meshes with the gear ring below the drive ring. The first gear is connected to the first housing. The first housing is rotatably connected to the first bracket. The wheel body is connected to the first housing. Multiple notches are equidistantly arranged in an annular pattern on the outer wall of the wheel body. The snap-fit ​​part can snap into the corresponding notch. The snap-fit ​​part is disposed on the spring piece. The extension part is disposed on the spring piece. The end of the extension part corresponds to the contact end of the contact switch. When the snap-fit ​​portion is not in contact with the notch on the wheel body, the extension portion is in contact with the contact switch.

[0018] Preferably, the bottom shell assembly further includes a battery, a pressure sensor, a vibration unit, and a magnetic charging head; The battery, the pressure sensor, the vibration unit, and the magnetic charging head are mounted on the protective shell. The pressure sensor is used to identify the pressure value of the environment in which the smartwatch is located.

[0019] One or more technical solutions provided in this application have at least the following technical effects or advantages: The present invention provides a multi-dimensional composite input control method and a smartwatch using the method. By distinguishing the pulse signal of the first input source into a step signal and a dwell signal, a single rotating structure can have at least two input forms, thereby increasing the input dimension without the need to add additional hardware sensors.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Furthermore, the term "and / or" in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0025] like Figure 1 As shown, this multidimensional composite input control method includes the following steps: S1. The system monitors the pulse signal generated by the first input source in real time and simultaneously monitors the trigger status of the second and third input sources. The first input source includes a rotary input structure that can output continuous level changes. The second and third input sources are used to provide directional or pattern auxiliary inputs. The system acquires the signals of the three sources in parallel to support subsequent multidimensional composite judgment.

[0026] S2. Perform time-domain analysis on the pulse signal of the first input source: If the duration of the pulse signal at the effective level is less than the preset time threshold, configure it as a step signal; if the duration of the pulse signal at the effective level is greater than or equal to the time threshold, configure it as a dwell signal; wherein, the time threshold is used to distinguish between fast instantaneous operation and dwell operation, thereby mapping a single hardware action to at least two different input types to enhance the input dimension.

[0027] S3. Based on the states of the second and third input sources, the step signal is processed in a first-level manner to generate a directional adjustment command. The first-level processing specifically includes: when the second input source is detected to be in a triggered state and a step signal is received simultaneously, the adjustment command is defined as a positive increment or page up; when the third input source is detected to be in a triggered state and a step signal is received simultaneously, the adjustment command is defined as a reverse decrement or page down; when neither the second nor the third input source is detected to be triggered, the adjustment command is defined as a unidirectional cyclic switching. The above processing can achieve directional determination without adding an additional directional trigger micro-reflective photoelectric sensor 410, thereby compensating for the unidirectional pulse output characteristics of the first input source in a software manner.

[0028] S4. Generate a state switching instruction based on the combination state of the dwell signal and the second or third input source; the presence of the dwell signal is used to prompt the system that the current input position can be confirmed or the function locked, so as to realize the combination multiplexing of dwell input and touch input, and thus support mode level switching.

[0029] The method is also equipped with a safety interlock mechanism: in the locked state, a single step signal, dwell signal or a single touch signal will not trigger a state switch; the unlocking process includes: first, triggering a dwell signal through a rotation operation, and during the period of maintaining the dwell signal, if a second input source is detected to be triggered, an unlock command or a confirmation entry command is generated; the interlock logic is used to prevent accidental triggering when there is underwater operation, vibration operation, motion operation or unintentional touch.

[0030] To assist blind operation, whenever a level transition of the pulse signal from the first input source is detected and it enters an active state, the vibration unit 14 is immediately driven to generate a short navigation vibration, indicating to the user that they are currently in a dwellable position. If the pulse signal remains unchanged within a preset window period after the navigation vibration is generated, the timing is automatically accumulated to trigger a dwell signal. The blind operation feedback mechanism is used to provide immediate tactile cues in environments without visual feedback (such as deep diving, nighttime, or sports scenarios), improving the certainty of operation and interaction efficiency.

[0031] The method is also equipped with signal tolerance latching logic: during the determination of the dwell signal, if high-frequency jitter of the pulse signal between the effective level and the ineffective level is detected, the duty cycle of the pulse signal is calculated; if the duty cycle is higher than the preset value, the system forcibly determines that the first input source is still in an effective contact state and maintains the operation of the timer until a clear displacement signal is detected; the above logic is used to perform fault-tolerant processing of power-off phenomena caused by micro-vibration, elastic hysteresis or tooth groove jitter of the mechanical structure, and avoid premature termination of dwell determination.

[0032] Monitoring of the second and third input sources is configured such that the system reads the background conductivity between the two input sources in real time and establishes a dynamic reference value. Only when the rate of change of the detected electrical signal exceeds a sudden change threshold set based on the dynamic reference value is it confirmed as a valid human touch trigger, thus filtering out false touch signals caused by the conductivity of the water. In underwater high-conductivity media environments, this strategy is used to improve the accuracy of capacitive or resistive tactile inputs.

[0033] When the system detects that the first input source continuously generates more than a preset number of step signals within a preset time period, and no dwell signal or trigger signal from the second or third input source is detected during this period, it is determined to be an abnormal operation by the user. The system will automatically trigger the highlight distress mode or reset to the safe default settings to ensure operational safety.

[0034] Furthermore, the following steps are also included: A1. Establish a system for parallel activation of the transmission optical path monitoring and dual-source parallel acquisition mechanism to monitor the pulse signal of the drive ring 3 and the sensing signal of the knob 41.

[0035] Since the first housing 44 is made of a transparent material with high transmittance to light of a specific wavelength, the detection beam of the miniature reflective photoelectric sensor 410 can directly penetrate the wall thickness of the first housing 44 and irradiate the surface of the inner cylinder 481.

[0036] The system is not limited by the rotation angle of the first housing 44. At any position of the drive ring 3, the miniature reflective photoelectric sensor 410 is in an effective detection state and can read the reflected signal of the identification end 483 on the straight cylinder 481 in real time.

[0037] A2. Signal processing for magnetically coupled through-type photoelectric input in the first operating mode: When the user does not apply axial force to the knob and directly rotates knob 41: The operating lever 42 drives the second magnetic ring 482 and the straight cylinder 481 to rotate synchronously through the attraction of the first magnetic ring 47.

[0038] The identification end 483 on the straight cylinder 481 moves across the monitoring area of ​​the miniature reflective photoelectric sensor 410 as the knob 41 rotates. The light signal passes through the transparent first housing 44 to complete the reflection circuit.

[0039] The system extracts specific signal changes generated by the recognition end 483 and identifies them as confirmation commands. Utilizing the damping connection characteristics between the straight tube 481 and the second bracket 49, the system only confirms a valid numerical lock or confirmation operation after detecting that the change in the light signal has stopped and maintaining the preset stabilization time.

[0040] A3. The axial displacement of the operating lever 42 is triggered only by the user's active push / pull operation: When the user actively overcomes the elastic resistance of the rubber diaphragm 411, if an axial force is applied to the operating lever 42, the operating lever 42 slides axially. This action causes the first magnetic ring 47 and the second magnetic ring 482 to be magnetically decoupled, and the first operating mode is physically disconnected; at the same time, the first magnet 61 enters the effective magnetic coupling area of ​​the auxiliary mechanism 6, i.e., the second operating mode.

[0041] When the user rotates the knob 41 while maintaining axial force, the first magnet 61 drives the second magnet 63 and the connecting rod 64 to move through magnetic field coupling, thereby causing the magnet group 67 on the back plate 65 to move.

[0042] The Hall sensor 66 senses the polarity reversal sequence and magnetic field strength changes of the first magnetic pole 671 and the second magnetic pole 672 in the magnet assembly 67 relative to the sensor. Based on this, the system generates continuous "analog adjustment commands".

[0043] Once a valid magnetic field change signal is detected from the Hall sensor 66, the system activates the mutual exclusion latch logic to forcibly ignore any background light signal fluctuations that may be generated by the miniature reflective photoelectric sensor 410, ensuring that the first mode will not be falsely triggered due to hand vibration or changes in light during the second mode operation.

[0044] A4. The system can monitor abnormal physical states: If the Hall sensor 66 detects that the magnetic field signal remains at the "critical coupling strength" (between the first and second modes) for an extended period without detecting a clear rotational change, the system determines that the operating lever 42 may be stuck due to a foreign object and has not fully rebounded. In this case, the system outputs a prompt on the interface and temporarily suspends the knob input function until a clear first-mode signal photoelectric signal becomes active again or a clear second-mode signal high-intensity magnetic field signal is detected, preventing erratic command jumps caused by unclear lever positions.

[0045] like Figures 2 to 13 As shown, another embodiment of the present invention also provides a smartwatch, including a bottom shell assembly 1, a touch unit 2, a drive ring 3, and a transmission unit 4; the touch unit 2 includes a touch screen and a housing; the bottom shell assembly 1 is connected to the housing, and the drive ring 3 is disposed on the outside of the housing and rotatably connected to the housing, for providing a rotary input signal from a first input source and triggering the pulse generation step in the multidimensional composite input control method.

[0046] The bottom shell assembly 1 includes a protective shell 11, a first contact end 15, a second contact end 16, and a circuit board 12. The circuit board 12 is connected to the protective shell 11. The first contact end 15 and the second contact end 16 are both connected to the circuit board 12 and are disposed on the side wall of the protective shell 11. They are used to provide touch signals from the second and third input sources in the multi-dimensional composite input control method to realize direction determination and dwell confirmation operations.

[0047] A gear ring is provided below the drive ring 3. The transmission unit 4 includes a first gear 43, a first housing 44, a first bracket 45, and a recording unit 5. The recording unit 5 includes a wheel body 51, a spring 52, a locking part 53, an extension part 521, and a contact switch 54. The first gear 43 meshes with the gear ring below the drive ring 3. The first gear 43 is connected to the first housing 44. The first housing 44 is rotatably connected to the first bracket 45. The wheel body 51 is connected to the first housing 44. Multiple notches 511 are provided annularly at equal intervals on the outer wall of the wheel body 51. The locking part 53 can be locked into the corresponding notch 511. The locking part 53 is provided on the spring 52. The extension part 521 is provided on the spring 52. The end of the extension part 521 corresponds to the contact end of the contact switch 54. When the locking part 53 is not in contact with the notch 511 on the wheel body 51, the extension part 521 is in contact with the contact switch 54.

[0048] The aforementioned mechanical structure is used to convert the user's continuous rotation of the drive ring 3 into alternating high and low level pulse signals, thus serving as the signal input basis for the first input source in the multi-dimensional composite input control method. The length of the protruding section on the wheel body 51 is proportional to the spacing of the notch 511, so that different rotation speeds result in different effective level durations, and the system executes the time-domain determination logic of the step signal and the dwell signal accordingly.

[0049] The bottom shell assembly 1 also includes a battery 13, a pressure sensor 17, a vibration unit 14, and a magnetic charging head 18. The battery 13, pressure sensor 17, vibration unit 14, and magnetic charging head 18 are mounted on the protective shell 11. The pressure sensor 17 is used to identify the pressure value of the environment in which the smartwatch is located, and triggers a safety interlock mechanism when a preset environmental threshold is reached, requiring the user to generate a dwell signal as a confirmation operation to avoid accidental triggering in underwater, motion, or environmental pressure changes.

[0050] In actual use, the user rotates the drive ring 3, which drives the first gear 43 to rotate via the gear ring, thereby causing the wheel body 51 to rotate synchronously. When the wheel body 51 rotates so that the locking part 53 is located on the protruding surface between the adjacent notches 511, the spring piece 52 is deformed under pressure, causing the extension part 521 to move outward and press the contact switch 54, generating a high-level signal; when the locking part 53 falls into the notch 511, the spring piece 52 resets, the contact switch 54 opens, generating a low-level signal, and so on to achieve pulse output.

[0051] Circuit board 12 receives the pulse signal and executes the multi-dimensional composite input control method: when the user quickly rotates the drive ring 3, the system determines it as a step signal, and if the user does not touch any side wall contact end, the interface performs unidirectional cyclic scrolling; if the user touches the first contact end 15 at the same time, the system executes a positive adjustment command to flip up the page or increase the value; if the user touches the second contact end 16, the system executes a reverse adjustment command to flip down the page or decrease the value.

[0052] When the user keeps the card contact 53 on the raised surface and the pulse signal remains at a high level for more than a time threshold, the system performs a dwell signal determination. At this time, the vibration unit 14 generates a short tactile feedback to prompt the user that the current interface is in a confirmable or switchable state. If the user touches the first contact end 15 further during the dwell phase, an unlock command or a confirmation command is output to complete the state switch.

[0053] In this embodiment, the smartwatch achieves pulse input through mechanical structure, direction and confirmation input through touch input, interlock constraints triggered by pressure sensor 17, blind operation prompts through vibration feedback, and executes a multi-dimensional composite input control method through circuit board 12, so that the hardware action chain and software decision chain form a closed interaction path, thereby realizing composite input control in complex scenarios.

[0054] Furthermore, the smartwatch in this embodiment uses crystal oscillator timing and electronic display, without using a balance wheel, hairspring, or magnetically coupled hands, thereby avoiding magnetic field input causing adsorption, lag, or timing errors, and improving operational stability in diving environments.

[0055] To further enhance the user's input methods during diving, a knob 41 is provided in the transmission unit 4. A rubber diaphragm 411 is provided on the outside of the knob 41, and the inner side of the rubber diaphragm 411 is sealed to the operating lever 42. The axial position change of the operating lever 42 is achieved by the elastic deformation of the rubber diaphragm 411, thereby enabling knob operation while maintaining the overall sealing of the watch body. The first housing 44 is made of transparent material.

[0056] A sliding sleeve 46 is fitted onto the outer wall of the operating lever 42, and a first magnetic ring 47 is mounted on the sliding sleeve 46. A second magnetic ring 482 can attract the first magnetic ring 47 at intervals. When the user rotates the knob 41, the first magnetic ring 47 drives the second magnetic ring 482 to rotate synchronously by magnetic force, realizing magnetic coupling torque transmission without mechanical penetration. To ensure that the rotary transmission and axial switching do not affect each other, a spline is provided on the operating lever 42, and a spline groove is provided on the knob 41. This spline guiding structure ensures that the axial sliding of the operating lever 42 relative to the knob 41 does not affect the rotary driving force applied by the knob 41 to the operating lever 42.

[0057] The second magnetic ring 482 is connected to the straight cylinder 481, which is rotatably connected to the second bracket 49. The second bracket 49 is fixedly connected to the protective shell 11. An identification end 483 is provided on the outside of the straight cylinder 481, which can be identified by the miniature reflective photoelectric sensor 410. The first shell 44 is made of transparent material, which does not affect the miniature reflective photoelectric sensor 410's ability to identify the identification end 483 on the straight cylinder 481 inside the first shell 44. This structure constitutes the first operating mode.

[0058] Furthermore, the straight cylinder 481 and the second support 49 are connected by a damped rotational connection. A preset frictional force exists between their rotating mating surfaces, allowing the straight cylinder 481 to produce a limited angular displacement relative to the second support 49 under external force, while remaining relatively stationary when no external force is applied, thus preventing erroneous input caused by mis-displacement. The magnetic attraction between the first magnetic ring 47 and the second magnetic ring 482 overcomes friction and achieves effective transmission.

[0059] Furthermore, it also includes a second operating mode, which can be switched by pushing the operating lever 42. The auxiliary mechanism 6 provided in this embodiment includes a first magnet 61, a stop block 62, a second magnet 63, a connecting rod 64, an annular seat 68, a fixing sleeve 69, a back plate 65, a magnet group 67, a Hall sensor 66, and a fixing frame 610.

[0060] The first magnet 61 is connected to the end of the operating lever 42. The stop block 62 is disposed on the inner wall of the fixed sleeve 69. The fixed sleeve 69 is mounted on the protective shell 11 through the fixing bracket 610. The end of the fixed sleeve 69 is in contact with the end of the first shell 44 and is in a fixed, non-rotating state. An annular seat 68 is installed in the internal cavity of the fixed sleeve 69. The annular seat 68 is rotatably connected to the connecting rod 64. The connecting rod 64 is connected to the second magnet 63. At the same time, the second magnet 63 is attached to the side of the stop block 62 away from the operating lever 42. The other end of the connecting rod 64 is connected to the back plate 65. A magnet assembly 67 is disposed on the back plate 65. The magnet assembly 67 consists of a first magnetic pole 671 and a second magnetic pole 672. One side of the magnet assembly 67 faces the Hall sensor 66. The magnetic poles of the first magnetic pole 671 and the second magnetic pole 672 facing the Hall sensor 66 have opposite directions, so that the Hall sensor 66 can identify the actual direction of the knob 41 during the rotation of the operating lever 42.

[0061] In the first operating mode, because the first magnetic ring 47 and the second magnetic ring 482 are attracted to each other, the first magnet 61 cannot drive the second magnet 63 to rotate, so the second operating mode is not effective. Conversely, when the first magnetic ring 47 and the second magnetic ring 482 are separated, the first magnet 61 can drive the second magnet 63 to rotate, thereby entering the second operating mode, so that the first operating mode and the second operating mode do not interfere with each other.

[0062] Furthermore, to prevent the rubber diaphragm 411 from moving arbitrarily due to water pressure issues, a pressure balancing mechanism is also included. The pressure balancing mechanism includes a compensation cavity formed inside the protective shell 11, a flexible diaphragm communicating with the compensation cavity and used to withstand external water pressure, a pressure frame for fixing the edge of the flexible diaphragm, and a limiting support structure for preventing excessive deformation of the flexible diaphragm. The external water pressure acts on the flexible diaphragm and reduces the volume of the compensation cavity, thereby balancing the pressure inside the compensation cavity with the external pressure to avoid structural pressure differences in the watch body. The specific structural composition here is familiar to existing smartwatches and is not limited here.

[0063] In the first operating mode, because the first magnetic ring 47 and the second magnetic ring 482 are attracted to each other, the first magnet 61 cannot drive the second magnet 63 to rotate, so the second operating mode is not effective. Conversely, when the first magnetic ring 47 and the second magnetic ring 482 are separated, the first magnet 61 can drive the second magnet 63 to rotate, thereby entering the second operating mode, so that the first operating mode and the second operating mode do not interfere with each other.

[0064] In actual use, the user applies a rotational torque to the knob 41 without applying any axial push / pull force. At this time, the operating lever 42 rotates synchronously with the knob 41 under the action of the spline and spline groove, but keeps its axial position unchanged. The operating lever 42 drives the sliding sleeve 46 and the first magnetic ring 47 on its outer side to rotate together. The first magnetic ring 47 attracts the second magnetic ring 482 through magnetic force and drives the second magnetic ring 482 and the straight cylinder 481 connected to it to rotate. After overcoming the preset friction force between the straight cylinder 481 and the second bracket 49, it generates a limited angular displacement. The recognition end 483 on its outer side is recognized by the miniature reflective photoelectric sensor 410. The photoelectric miniature reflective photoelectric sensor 410 outputs the corresponding photoelectric signal. The system recognizes the rotation process as a digital input process in the first operation mode.

[0065] Specifically, when the operating lever 42 drives the back plate 65 to move, the Hall sensor 66 senses the change in magnetic flux passing through its surface. If a change in the magnetic field signal from the first polarity (e.g., high level corresponding to the N pole) to the second polarity (e.g., low level corresponding to the S pole) is detected, the system determines it as the first rotation direction (e.g., clockwise); conversely, if a change in the magnetic field signal from the second polarity to the first polarity is detected, the system determines it as the second rotation direction (e.g., counterclockwise). This logic utilizes the signal phase difference or level transition sequence generated by the alternating positive and negative magnetic poles to identify the actual adjustment intention of the knob 41.

[0066] When the user needs to switch to the second operating mode, an axial push / pull force is applied to the knob 41, pointing towards the inside of the watch body or away from the watch body. The operating lever 42 slides axially under the guidance and constraint of the spline and spline groove, causing the first magnet 61 at its end to move along the axial direction of the fixed sleeve 69. As the axial displacement of the operating lever 42 increases, the first magnetic ring 47 gradually moves away from the second magnetic ring 482, weakening the magnetic attraction between them until it basically fails, thereby interrupting the magnetic coupling transmission link from the first magnetic ring 47 to the second magnetic ring 482, making the transmission path of the first operating mode in a failed state. At the same time, the first magnet 61 enters the magnetic coupling area inside the fixed sleeve 69 and forms an effective magnetic connection with the second magnet 63. Under the limiting action of the stop block 62, the second magnet 63 is constrained within a predetermined axial position range.

[0067] Under the continuous action of the axial push / pull force, the user continues to rotate the knob 41. The operating lever 42 rotates around the axis while maintaining axial offset. The first magnet 61 rotates with the operating lever 42 and drives the second magnet 63 to rotate around the rotating connection of the annular seat 68 through magnetic force. This drives the connecting rod 64 and the back plate 65 fixed thereto to rotate. The magnet group 67 on the back plate 65 generates a change in the magnetic pole position relative to the Hall sensor 66. The Hall sensor 66 sequentially senses the change sequence of the magnetic field polarity of the first magnetic pole 671 and the second magnetic pole 672. The system interprets this change sequence as a continuous analog quantity adjustment command in the second operation mode. In order to avoid false alarms, the annular seat 68 and the connecting rod 64 are damped. However, the magnetic force between the first magnet 61 and the second magnet 63 can overcome the friction between the annular seat 68 and the connecting rod 64 and cause rotation.

[0068] When the user completes the adjustment operation in the second operating mode and releases the axial push / pull force on the knob 41, the rubber diaphragm 411, under its own elastic recovery and the combined action of the internal parts' positioning, drives the operating lever 42 to return to its initial axial position. The first magnet 61 then exits the magnetic coupling area with the second magnet 63. The second magnet 63, constrained by the stop block 62, connecting rod 64, and ring seat 68, stops rotating further, and the second operating mode automatically becomes invalid. Simultaneously, after the operating lever 42 returns to its original position, the first magnetic ring 47 approaches and attracts the second magnetic ring 482, restoring the magnetic coupling transmission relationship with the straight cylinder 481, allowing the system to return to the standby state where the first operating mode is available, thus achieving automatic switching and reset from the second operating mode to the first operating mode.

[0069] Example 1: This embodiment uses the example of a diver adjusting the "maximum depth alarm value" and "oxygen partial pressure setting" to explain in detail the specific process of interaction logic and hardware response coordination: First, in the main interface menu selection stage, in order to quickly move the cursor to the "depth setting" option, the user needs to continuously press and hold the second contact end 16, which is defined as the page-down function, and quickly rotate the drive ring 3. At this time, the internal wheel 51 rotates accordingly, and the notch 511 on it cooperates with the locking part 53, forcing the spring piece 52 to undergo elastic deformation and driving the extension part 521 to periodically press the contact switch 54. The system receives the high-frequency pulse signal and combines it with the touch signal to execute the rapid scrolling operation of the menu list. After entering the setting interface, for the "maximum depth alarm value," which requires a large adjustment from 10 meters to 40 meters, the user needs to overcome the elasticity of the rubber diaphragm 411 to push the knob 41 inward and keep pressing and rotating it, causing the operating lever 42 to rotate. Axial sliding decouples the first magnetic ring 47 from the second magnetic ring 482. Simultaneously, the first magnet 61 enters the coupling area, driving the back plate 65 to rotate. The Hall sensor 66 senses the continuous magnetic field changes generated by the magnet group 67. Based on this, the system determines the second operating mode, and the command value rapidly jumps in units of 5 meters or 10 meters. When the value approaches the target value (e.g., 40 meters) and confirmation or fine-tuning such as "oxygen partial pressure" that requires precision to 0.01 bar is needed, the user releases the thrust and only lightly rotates the knob 41. The operating lever 42 resets, the first magnetic ring 47 re-attaches and drives the straight cylinder 481 to rotate. The miniature reflective photoelectric sensor 410 detects the reflected signal from the identification end 483 on the straight cylinder 481 through the transparent first housing 44. The system switches back to the first operating mode, and one physical rotation corresponds to an increment of 0.1 or 0.01 in the software value, thereby achieving seamless switching and confirmation from coarse to fine adjustment.
