Description

Technical Field

[0001] This invention relates to the field of smart wearable devices and vehicle human-machine interaction technology, and in particular to a detachable smart bracelet module on a steering wheel and a vehicle. Background Technology

[0002] With the development of smart cars and wearable devices, users want to access information and control vehicle functions safely and conveniently while driving, and also enjoy the convenience of health monitoring and notification reminders from smart bracelets outside the car. However, existing technologies have the following shortcomings: 1. Operating smart bracelets or mobile phones while driving can distract drivers and increase the risk of accidents.

[0003] 2. Data and functional gaps exist between vehicles and personal wearable devices, making it impossible to create a continuous and unified user experience.

[0004] 3. Users need to have both a smartwatch / band and a vehicle interaction system, resulting in functional redundancy and low hardware utilization.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0024] Figure 1 This is a schematic diagram of the overall structure of a detachable smart bracelet module on a steering wheel according to an embodiment of the present invention. Figure 1 Embodiments of the present invention provide a detachable smart bracelet module for a steering wheel, the detachable smart bracelet module for a steering wheel comprising: The smart bracelet body 1 includes a display screen 11; The main dock 2 is embedded in the spokes of the steering wheel and has an internal mounting slot 21 that matches the smart bracelet body 1. The smart bracelet body 1 is detachably installed in the mounting slot 21. When the smart bracelet body 1 is installed in the mounting slot 21, the module is in the vehicle interaction mode. The smart bracelet body 1 establishes a physical or wireless connection with the host dock 2, establishes a data channel with the vehicle system, and provides the vehicle system with the user identity identifier stored in the smart bracelet body 1 to trigger vehicle personalization settings. The display screen 11 switches to the vehicle user interface that displays driving-related information. When the smart bracelet body 1 is removed from the mounting slot 21, the module is in independent wear mode. The smart bracelet body 1 is disconnected from the vehicle and operates as an independent wearable device. The display screen 11 switches to a standard user interface that displays personal health data.

[0025] Specifically, the steering wheel adopts a conventional three-spoke or four-spoke design. The main unit dock 2 is embedded in the spokes of the steering wheel, and the main unit dock 2 has a mounting slot 21 that matches the smart bracelet body 1. The smart bracelet body 1 is detachably installed in the mounting slot 21 of the main unit dock 2. The main unit dock 2 is fixedly connected to the steering wheel frame with screws or clips, so that the smart bracelet body 1 can be worn on the steering wheel handle as if it were worn on the wrist. The outer surface of the main unit dock 2 is flush with the surface of the steering wheel and is covered with leather or soft rubber of the same material as the steering wheel to ensure aesthetics and grip. The surface design of the main unit dock 2 is integrated with the shape of the steering wheel. After the smart bracelet 1 is inserted into the mounting slot 21, its display screen 11 and buttons are located in a comfortable area that the driver's thumb can easily operate, while ensuring that the electrode pads for detecting signals such as blood oxygen can be gripped when the driver holds the steering wheel.

[0026] The smart bracelet body 1 resembles a regular smart bracelet in appearance, but the strap is simplified or eliminated. Its back features two sets of Pogo Pin contacts and a strong magnet. When the user brings the smart bracelet body 1 close to the main unit dock 2, the magnetic force guides the bracelet to automatically fall into the mounting slot 21, and the Pogo Pins connect with the contacts in the main unit dock 2. The main unit dock 2 is connected to the vehicle's CAN bus, power system, and vehicle infotainment system via wiring harnesses. When the smart bracelet body 1 is installed in the mounting slot 21, it establishes a physical or wireless connection with the main unit dock 2 on the steering wheel. The bracelet body 1 receives vehicle signals and switches to in-vehicle interaction mode, displaying driving-related information on the screen 11. The screen 11 automatically switches to a simplified automotive-grade UI, displaying key driving information such as vehicle speed, simplified navigation instructions, battery level, time, or customizable shortcut controls. This solves the problem of distraction caused by operating a smart bracelet while driving, providing a safe and convenient interaction method that allows the driver to view and operate the device without taking their eyes off the road. When the smart bracelet body 1 is removed from the mounting slot 21, the smart bracelet body 1 disconnects from the vehicle and switches to independent wear mode, operating as an independent wearable device. The display screen 11 performs personal health monitoring functions and displays a standard user interface for personal health data.

[0027] When the smart bracelet body 1 is installed into the mounting slot 21, the module is in vehicle interaction mode, and the smart bracelet body 1 establishes a physical or wireless connection with the host dock 2. Specifically, the physical connection includes, but is not limited to: contact electrical connection through the multi-contact (Pogo Pin) on the back of the smart bracelet body 1 and the gold-plated probe in the mounting slot 21, or plug-in connection through a micro universal interface such as USB-C, or contact connection through an electrical contact. The wireless connection includes, but is not limited to: NFC, BLE, Wi-Fi Direct, millimeter wave, etc. Among them, Near Field Communication (NFC) is used for fast pairing and identity recognition, Bluetooth Low Energy (BLE) is used for continuous data exchange and audio transmission, Wi-Fi Direct is used for high-bandwidth data synchronization, and 60GHz millimeter wave communication is used to achieve extremely low latency raw sensor data stream transmission. At the same time, the smart bracelet body 1 establishes a two-way data channel with the vehicle system and provides the vehicle system with the user identity identifier stored in the smart bracelet body 1 to trigger vehicle personalization settings, and the display screen 11 switches to an in-vehicle user interface displaying driving-related information.

[0028] Unlike existing technologies where smart bracelets and vehicles only have loosely coupled connections via Bluetooth for simple music playback or phone calls, this invention establishes a deep, bidirectional electrical signal connection that supports multi-type data fusion. Existing connection methods lack access to the vehicle's underlying bus (such as the CAN bus) and cannot utilize steering wheel-embedded sensors (such as grip detection sensors). Therefore, they cannot achieve automatic switching of function modes, proactive user identification, triggering of personalized vehicle settings, or contextual adaptive adjustments to the user interface. In this invention, when the smart bracelet 1 establishes a connection with the host dock 2 via the aforementioned physical or wireless methods, not only is power supply and pairing completed, but more importantly, a high-bandwidth, low-latency data fusion channel is established. This channel allows the processing unit inside the smart bracelet 1 to directly access the grip detection sensor located in the host dock 2. Simultaneously, the vehicle's infotainment system can also read data monitored by the health monitoring sensor within the smart bracelet 1 in real time. This cross-device sensor data interoperability and collaborative computing capability is the core of this invention. It is precisely because of this deep electrical connection that the system can automatically identify the user's identity and trigger a series of complex personalized settings and interface switching actions that require deep involvement from the vehicle system, thus achieving a leap from simple connection to deep collaboration.

[0029] For example, user A enters the vehicle carrying their paired smart bracelet 1 and inserts it into the main dock 2. The accelerometer inside the smart bracelet 1 detects changes in stationary and charging states, and combined with contact activation signals, automatically determines that the vehicle has entered in-vehicle interaction mode. The smart bracelet 1 sends its stored unique user ID (such as a BLE pairing code or an encrypted UUID) to the vehicle via the contact points. Upon receiving the ID, the vehicle control system retrieves user A's preference settings from the local machine or cloud: the seat automatically moves to the preset position, the rearview mirror unfolds to the memory angle, the air conditioning is set to 22°C, and the media player resumes playing the last song. Simultaneously, the display screen 11 switches to a simplified UI, showing the current vehicle speed, the next navigation arrow, time, and battery level. This achieves seamless identity switching and personalized settings; when different drivers use the vehicle, it can automatically identify the user and synchronize their personalized vehicle settings (seat, music, air conditioning, etc.).

[0030] Upon reaching their destination, the user removes the smart bracelet 1 and wears it on their wrist. The smart bracelet 1 detects that the contact point has disconnected and the acceleration signal matches the wearing characteristics, automatically switching back to independent wear mode. The display 11 reverts to a normal watch face and begins recording heart rate, steps, etc. Data such as heart rate fluctuations and average stress levels during the drive are synchronized to the mobile app via Bluetooth and merged with the user's daily health records. This breaks down the barriers between in-vehicle and out-of-vehicle data and functions, providing a hardware platform that serves both as part of deep vehicle interaction and as the user's personal wearable device.

[0031] The software and control system reside within both the smart bracelet itself and the vehicle's infotainment system, responsible for enabling two-way communication, switching between operating modes, data synchronization, identity recognition, and vehicle function mapping. It is the first device to achieve a detachable, integrated design between the steering wheel assist component and the independent smart bracelet, breaking down the functional separation between driving and everyday scenarios, allowing one device to meet dual needs. By automatically recognizing the installation status of the smart bracelet, it achieves seamless switching between in-vehicle interaction mode and independent wearable mode, requiring no manual user setup and making operation extremely user-friendly.

[0032] The technical solution of this invention, through a detachable structure and automatic dual-mode switching, achieves seamless reuse of the smart bracelet in both in-vehicle and daily driving scenarios. In in-vehicle mode, it automatically loads personalized settings and switches to a driving-specific interface, reducing driver distraction and improving safety and convenience. It enables safe, convenient, and efficient human-machine interaction during driving, reducing the risk of traffic accidents caused by device operation. It constructs a continuous intelligent experience centered on the user, breaking down data and functional barriers between vehicles and personal devices. Through a low-cost solution for deeply personalized driving, it enhances the user's sense of belonging and the level of intelligence in the vehicle. Through hardware reuse and scenario-based design, users do not need to purchase two sets of devices, improving hardware utilization and enhancing the practical value and economy of individual hardware devices, aligning with green design principles. In summary, this invention solves the problem of driver distraction caused by operating a smart bracelet while driving, achieving a unified approach of multi-functionality, safe driving, and continuous intelligent experience, reducing driver distraction and improving safety and convenience.

[0033] Figure 2 This is a schematic diagram of a mainframe dock provided according to an embodiment of the present invention, with reference to... Figure 1 and Figure 2 Optionally, the main dock 2 includes: a vehicle interface 22 that is connected to the vehicle bus or vehicle infotainment system for communication; A connection structure is provided between the smart bracelet body 1 and the host dock 2. The connection structure includes: a mechanical fixing component 23 and an electrical connection component 24. The mechanical fixing component 23 includes a snap-fit ​​structure or a strong magnetic adsorption component disposed in the mounting groove 21 for physically fixing the smart bracelet body 1; The electrical connection component 24 includes contacts disposed on the back of the smart bracelet body 1 and probes or wireless charging coils disposed in the mounting slot 21, for power supply and data transmission when the smart bracelet body 1 is installed.

[0034] Specifically, the main dock 2 is configured as an embedded component at the steering wheel spokes, with an internal mounting slot 21 that matches the shape of the smart bracelet body 1. The main dock 2 includes: a vehicle interface 22, a mechanical fixing component 23, and an electrical connection component 24.

[0035] The vehicle interface 22 is connected to the vehicle's CAN bus or in-vehicle infotainment system (vehicle system) via a wiring harness. It is used to realize the command and data interaction between the host dock 2 and the vehicle control system, and can receive vehicle power to power the smart bracelet body 1.

[0036] Mechanical fixing component 23 is disposed on the inner wall of mounting groove 21, employing a combination of a strong magnetic adsorption component and a snap-fit ​​structure. The strong magnetic adsorption component includes a permanent magnet embedded in the bottom of mounting groove 21 and a magnetic conductive sheet positioned corresponding to the back of the smart bracelet body 1. The snap-fit ​​structure includes elastic claws on both sides of mounting groove 21; when the bracelet is pushed into mounting groove 21, the claws automatically engage with positioning grooves on the sides of the bracelet, providing additional anti-pull-out force. This dual-fixing design ensures that the bracelet will not accidentally detach when the vehicle is traveling on bumpy roads or making emergency turns.

[0037] The electrical connection component 24 adopts a hybrid design: on the one hand, six gold-plated spring probes (Pogo Pins) are provided at the bottom of the mounting slot 21, and six circular metal contacts are provided at corresponding positions on the back of the smart bracelet body 1 for transmitting power and low-speed control signals; on the other hand, a Qi standard wireless charging coil and a millimeter-wave communication chip are integrated in the mounting slot 21 and the bracelet body respectively, for realizing contactless fast charging and high-speed data transmission. When the bracelet is inserted into the mounting slot 21, the user can choose to make a traditional connection through the contacts or a blind-plug connection wirelessly, with the two methods serving as backups for each other.

[0038] This embodiment employs a dual-fixation design using a snap-fit ​​structure and a strong magnetic adsorption component. This ensures stability while driving (withstanding the tension and vibration during steering) while allowing for quick and easy disassembly, and it is also compatible with steering wheel grips of different diameters. The contacts on the back of the smart bracelet and the probes in the mounting slot are used to charge the smart bracelet and facilitate bidirectional communication with the vehicle's infotainment system. Due to the latency of wireless communication sensors, the wireless charging coil is primarily used for charging. This improves hardware utilization and user experience, avoids functional redundancy, achieves multiple uses, and provides a dedicated and convenient fixing and charging location for the smart wearable device within the vehicle. This embodiment uses an electrical contact interface combined with magnetic adsorption or mechanical locking, ensuring the stability of the bracelet's connection to the main unit while the vehicle is in motion (including steering vibrations and rapid acceleration / deceleration), while also allowing for quick one-handed removal and placement, balancing reliability and convenience.

[0039] Continue to refer to Figure 1 and Figure 2 Optionally, the main dock 2 also includes: a charging module 25 and a data communication module 26; The charging module 25 is used to wirelessly charge the smart bracelet body 1 in conjunction with the wireless charging coil when the smart bracelet body 1 is installed on the host dock 21. The data communication module 26 is used to establish a high-speed data transmission channel with the probe when the smart bracelet body 1 is installed on the host dock 21.

[0040] Specifically, the charging module 25 is connected to the wireless charging coil in the vehicle interface 22 and the electrical connection assembly 24. When the vehicle is in motion, the charging module 25 performs fast charging at a maximum power of 15W; when the vehicle is turned off and the wristband's battery level is above 80%, charging is automatically suspended to protect the battery.

[0041] Data communication module 26 is connected to the probe and millimeter-wave chip in electrical connection assembly 24. In contact connection mode, data communication module 26 communicates via I... 2 The C or UART protocol is used to exchange low-speed configuration information (such as user ID and mode switching commands) with the wristband; in wireless mode, the millimeter-wave communication chip operates in the 60GHz band and can establish an equivalent data transmission rate of up to 6Gbps, which is used to transmit raw data of physiological signals such as driver's heart rate and blood oxygen in real time, as well as vehicle navigation and media streaming information, with a latency of less than 5 milliseconds.

[0042] Once the smart bracelet body 1 is inserted into the mounting slot 21 and locked, the vehicle interface 22 wakes up the vehicle system via the CAN bus. The data communication module 26 reads the user's unique identifier stored in the bracelet, triggering personalized settings such as seat and rearview mirror adjustments. Simultaneously, the charging module 25 begins to recharge the bracelet's battery. The entire connection process requires no pairing or confirmation from the user, achieving a seamless plug-and-play experience. This ensures reliable connectivity in a driving environment while providing high-bandwidth, low-latency data interaction capabilities, laying the hardware foundation for advanced functions such as driver status monitoring and in-vehicle entertainment collaboration.

[0043] To prevent contact oxidation, the main dock 2 employs wireless charging and millimeter-wave communication. The main dock 2 houses a 60GHz millimeter-wave communication chip and a Qi wireless charging coil. The smart bracelet itself contains a millimeter-wave antenna array and a receiving coil. After the bracelet is magnetically positioned, wireless charging automatically begins, with an adjustable power of 5W-15W. Simultaneously, a millimeter-wave link is established, providing an equivalent data transmission rate of up to several Gbps for transmitting raw driver physiological signals, vehicle infotainment data, etc. Due to the absence of physical contacts, the entire module achieves IP67 waterproof and dustproof ratings, and the bracelet surface can be completely sealed, making it easier to clean.

[0044] The main dock in this embodiment uses wireless charging and near-field communication technology, eliminating exposed electrical contacts, improving waterproof and dustproof performance, and avoiding poor contact problems caused by contact oxidation or wear, thereby enhancing the product's durability and premium feel.

[0045] Optionally, vehicle personalization settings include at least one of the following: seat position, rearview mirror angle, air conditioning settings, music playlist, frequently used navigation addresses, and driving mode preferences; The smart bracelet itself is also used as a digital key to start or unlock the vehicle.

[0046] Specifically, when the smart bracelet is inserted into the main unit dock on the steering wheel, the two are physically connected via an interface to establish a high-speed data channel. Alternatively, it can be designed to communicate and power via Bluetooth and wireless charging. The vehicle automatically reads the user's unique ID built into the smart bracelet and wakes up the vehicle's infotainment system, automatically loading all personalized vehicle settings bound to that ID (seat position, rearview mirror angle, air conditioning preferences, frequently used navigation addresses, etc.). Furthermore, the smart bracelet can also function as a digital key, possessing digital key functionality (UWB+NFC+BLE), reducing the burden on users carrying physical keys and enhancing the product's practicality.

[0047] This embodiment uses the user's identity identifier within the wristband to trigger multi-dimensional vehicle personalization settings, achieving a seamless "personalized upon entering the vehicle" experience; at the same time, as a digital key, it further expands the functional boundaries of the wristband and reduces the burden on users carrying physical keys.

[0048] Figure 3 This is a schematic diagram of the internal structure of a smart bracelet body according to an embodiment of the present invention, with reference to... Figure 2 and Figure 3 Optionally, the main dock 2 also includes a grip detection sensor 27, which is used to detect whether the driver's hands are gripping the steering wheel; The smart bracelet body 1 also includes: a health monitoring sensor 12, a processing unit 13, a wireless communication unit 14, a vibration motor 15, and a battery 16; Battery 16 is connected to vibration motor 15, display screen 11 and processing unit 13, and battery 16 is used to provide power. The processing unit 13 is connected to the display screen 11, the health monitoring sensor 12, the grip detection sensor 27, the wireless communication unit 14, and the vibration motor 15. The wireless communication unit 14 is used to synchronize personal health data with the mobile phone. The processing unit 13 is used to integrate the grip signal from the grip detection sensor 27 and the driver's physiological signal from the health monitoring sensor 12 in the vehicle interaction mode, and generate the driver status monitoring result for display on the display screen 11 or the vehicle system. The processing unit 13 is also used to issue a tactile alarm via the vibration motor 15 when it determines that the driver's state is abnormal, and / or issue a visual or auditory alarm to the driver via the vehicle system, and / or issue an intervention request to the vehicle's ADAS system to perform deceleration or pull-over actions.

[0049] Specifically, the health monitoring sensor 12 may include a blood oxygen sensor and a heart rate sensor. Driver physiological signals include at least one of heart rate, stress, blood oxygen saturation, or skin conductance; driver status monitoring results include at least one of fatigue, stress, or abnormal health conditions. The grip detection sensor 27 in the docking station 2 can detect whether the driver's hands are gripping something. Combined with the heart rate sensor in the smart bracelet body 1, advanced driver status monitoring can be achieved, such as detecting driving stress and fatigue (heart rate variability analysis), and issuing alerts via a vibration motor and display screen when abnormalities occur. Incoming vehicle calls, message notifications, etc., are prioritized for display on the bracelet's display screen 11 and are alerted via steering wheel vibration (using the docking station 2 or vibration motor 15) to minimize interference with driving.

[0050] To address driving safety needs, the wristband's form factor has been optimized (fitting to the steering wheel and without operational interference), integrating driver-specific functions (heart rate warning, tire pressure linkage, and wake-up-free voice control), rather than simply porting conventional wristband functions. Utilizing a multi-data collaborative algorithm, it integrates driver heart rate data and vehicle driving data (speed, gear, tire pressure) to determine fatigue driving and health abnormalities, improving warning accuracy and preventing false triggers.

[0051] For example, the main dock 2 is embedded with a capacitive grip detection sensor 27, which can detect whether the driver's hand is covering the steering wheel. The back of the smart bracelet body 1 integrates a photoelectric heart rate sensor and a blood oxygen sensor. When the smart bracelet body 1 is inserted into the main dock 2, its back is in close contact with the surface of the steering wheel, and the surface of the steering wheel has a transparent window at the corresponding position, so that the sensor can detect the heart rate signal of the driver's palm at the base of the hand holding the steering wheel through the window.

[0052] During vehicle operation, the processing unit 13 collects heart rate signals in real time and performs heart rate variability (HRV) analysis. Simultaneously, it reads the signal from the grip detection sensor 27 to confirm that the hand is on the steering wheel. If the analysis reveals a continuously increasing low-frequency / high-frequency power ratio, combined with vehicle lateral acceleration data (manifested as frequent minor steering adjustments), it determines that the driver is fatigued. At this time, the vibration motor 15 emits pulsed vibrations, and the vehicle's central control screen displays a "Restraint Recommendation" prompt, accompanied by a voice announcement: "You seem somewhat fatigued; there is a service area 3 kilometers ahead." If an extreme abnormality in heart rate is detected (e.g., exceeding 180 or falling below 40 accompanied by a sudden drop in blood oxygen), it is determined to be a health emergency. The module immediately sends a highest-priority intervention request to the vehicle's ADAS system: automatically activating hazard lights, reducing vehicle speed, guiding the vehicle safely to the side of the road using the driver assistance system, and automatically dialing emergency assistance.

[0053] In a specific application scenario, when the user inserts the smart bracelet body 1 into the mounting slot, the electrical connection component 24 immediately establishes a physical connection. At this time, the processing unit 13 within the smart bracelet body 1 sends a data packet containing the user ID to the vehicle system through this connection. After verifying the ID, the vehicle system retrieves parameters such as seat position and rearview mirror angle associated with that ID from the CAN bus via the vehicle interface 22 and performs adjustments. Simultaneously, the processing unit 13 begins to read data from the grip detection sensor 27 located in the main dock 2 in real time to determine whether the driver's hands are on the steering wheel. Furthermore, the processing unit 13 also fuses and calculates the driver's physiological signals collected by its integrated health monitoring sensor 12 (such as a heart rate sensor) with the data from the grip detection sensor 27 through the same data channel. For example, the heart rate data analysis result is only used to determine the driver's fatigue state when the grip detection sensor 27 confirms that the hand is on the steering wheel. This cross-hardware, cross-system sensor data collaborative access and fusion calculation is impossible to achieve with existing technologies that only use Bluetooth connections for simple data transmission, representing a significant breakthrough in human-machine interaction and driving safety.

[0054] This embodiment integrates a wristband biosensor and a steering wheel grip sensor. Compared to monitoring solely based on driving behavior or a single physiological signal, it can more accurately determine the driver's actual physiological state while "holding the steering wheel," providing a more reliable data foundation for driver status monitoring. It achieves a complete safety closed loop from "monitoring" to "early warning" to "active intervention." When fatigue or health abnormalities are detected, it not only alerts the driver through touch / vision / hearing but also triggers the ADAS system to decelerate or pull over, significantly improving driving safety, especially in scenarios involving sudden illnesses (such as myocardial infarction or hypoglycemia), offering significant protective value.

[0055] Figure 4 This is a schematic diagram of the external structure of a smart bracelet body according to an embodiment of the present invention, with reference to... Figure 4 Optionally, physical buttons 17 are provided on one or both sides of the shell of the smart bracelet body 1; Physical button 17 is used when the module is in the vehicle interaction mode. It is remapped by the vehicle system as a high-frequency function key for the vehicle, used for voice assistant activation, media playback control, answering or hanging up calls, and turning cruise control on or off.

[0056] Specifically, physical button 17 is remapped to high-frequency vehicle function keys, such as: one-click activation of the voice assistant, changing songs, answering / hanging up calls, cruise control switch, etc. The driver can operate it with their thumb without lifting their hand, achieving "blind operation".

[0057] In this embodiment, the original physical buttons on the wristband are remapped to high-frequency vehicle function keys in vehicle mode, enabling drivers to operate blindly without raising their hands or searching for the touchscreen. This conforms to driving ergonomics and significantly reduces the risk of distraction.

[0058] Continue to refer to Figure 3 Optionally, the smart bracelet body 1 also includes: a charging management unit 18; The charging management unit 18 is connected to the processing unit 13. The charging management unit 18 is used to dynamically adjust the charging strategy of the battery 16 based on the power state of the vehicle and the charge of the battery 16.

[0059] Specifically, as soon as the smart bracelet 1 is inserted into the main dock 2, wireless or wired fast charging begins. This ensures that every drive is a recharging process, eliminating the need for users to worry about the bracelet's battery level. In in-vehicle interaction mode, it communicates stably with the vehicle's infotainment system, while in independent wearable mode, it efficiently synchronizes with the user's smartphone. Simultaneously, it controls the bracelet's power consumption, guaranteeing 2-3 days of use on a single charge (8 hours / day in driving mode + daily use in independent mode). The steering wheel can charge the bracelet while driving, ensuring it's fully charged when the drive ends.

[0060] For example, the battery 15 in the smart bracelet body 1 can have a capacity of 300mAh. When the smart bracelet body 1 is inserted into the main dock 2, the charging management unit 18 first detects the vehicle's power status (whether the engine is running, battery voltage). If the vehicle is in motion (powered by the alternator), 15W fast charging is used to fully charge the bracelet; if the vehicle is off but unlocked, only 2.5W trickle charging is used to prevent the battery from being depleted. When the bracelet's battery level is above 90%, charging automatically stops and resumes when the level drops to 70% to optimize battery cycle life. On average, each 30-minute drive replenishes about 20%-30% of the battery, enough to support the bracelet's independent use for a whole day.

[0061] This embodiment automatically charges the wristband during each driving session, ensuring that the wristband is always in a high-battery state, completely solving the user pain point of frequent charging of smart wearable devices, and realizing a seamless battery life experience of replenishing power as you drive.

[0062] Optionally, the smart bracelet itself also includes: a data synchronization unit; The data synchronization unit is connected to the wireless communication unit. When the module is in the vehicle interaction mode, the data synchronization unit records the driver's health data and driving behavior data and stores it in the smart bracelet body. The data synchronization unit is also used to automatically synchronize data with the paired mobile terminal or cloud server via the wireless communication unit after the module switches to independent wearable mode.

[0063] Specifically, when a user gets out of the car, they can easily remove the smart bracelet (Bracelet 1) and wear it on their wrist. The smart bracelet (Bracelet 1) automatically switches back to the personal wearable device UI and continues to perform routine functions such as health monitoring, activity recording, and receiving notifications. Driving-related health data recorded by the smart bracelet (Bracelet 1) in in-car interaction mode (such as heart rate changes and stress levels during the trip) is synchronized to the bracelet's app, forming a complete personal health and activity profile. Integrating driving behavior data into personal health management provides users with a more comprehensive health view, enhancing user engagement and the product's data value.

[0064] This embodiment integrates health data during driving (such as heart rate fluctuations and stress levels) with daily health records, forming a complete closed loop of human-vehicle-life data. Users can not only see daily activity data, but also review their physiological state while driving, which helps with health management and driving behavior improvement.

[0065] Optionally, the outer surface of the main dock is flush with or smoothly transitions to the surface of the steering wheel, and the mounting position of the main dock on the steering wheel is set as follows: When the driver holds the steering wheel in a standard grip, the display screen and physical buttons are within the reach of the driver's thumb.

[0066] Specifically, it ensures that the operating interface is always located in the area naturally accessible to the driver's thumb, thus guaranteeing driving safety from a physical design perspective and improving the product's ease of use and comfort.

[0067] This embodiment utilizes ergonomic optimization to ensure that the wristband is installed on the steering wheel in the area naturally reached by the driver's thumb, with the screen and buttons facing the driver's line of sight. This allows for information reading and operation without affecting the driver's normal grip posture, further enhancing driving safety.

[0068] Embodiments of the present invention also provide a vehicle that includes a detachable smart bracelet module on the steering wheel provided in any embodiment of the present invention.

[0069] The detachable smart wristband module for steering wheels provided by this invention can be pre-installed as an original component during vehicle manufacturing or provided as an aftermarket accessory for existing vehicle users. It has a compact structure, good compatibility with vehicle electronic and electrical systems, and possesses extremely high industrial practical value and market prospects.

[0070] Since the vehicle includes the detachable smart bracelet module on the steering wheel provided in any embodiment of the present invention, the beneficial effects of the vehicle and the detachable smart bracelet module on the steering wheel are the same, and will not be repeated here.

[0071] The specific embodiments described above do not constitute a limitation on the scope of protection of this invention. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this invention should be included within the scope of protection of this invention.
