[0015] Figure 1 The process of the seat status monitoring method of the embodiment of the present invention is as follows Figure 1 ;

[0016] Figure 2 The process of the seat status monitoring method of the embodiment of the present invention is as follows Figure 2 . DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] The embodiment of the present invention provides a seat status monitoring method, combining Figure 1 As shown, the steps include:

[0019] Obtain passenger information through a human-computer interaction interface and generate seat status information; obtain passenger basic information such as age, height, weight, etc. through a human-computer interaction interface (such as a touch screen, voice recognition or other input devices), which can be input by the user, and the system will generate corresponding seat status information based on this information; for example, for a child safety seat, the seat status information may include suitable seat group, seat height, cushion position, etc.; this step can generate seat status information through accurate passenger information, ensuring that the seat can be personalized according to the characteristics of the passenger each time it is used, improving comfort and safety, and at a low cost;

[0020] According to the content corresponding to the expected status information of the seat, the actual status information of the seat is obtained; the actual status information of the seat is obtained in real time through the built-in sensors of the seat (such as pressure sensors, position sensors or other status detection modules), which can detect the actual height, position, angle, locking status, etc. of the seat, so as to ensure that the status of the seat can be monitored in real time; the actual status information of the seat can also be viewed and obtained by the user himself; by monitoring the status of the seat in real time, it can be timely discovered whether the seat has position deviation or is not adjusted to a suitable state, thereby avoiding improper human operation or failure of seat adjustment, and improving safety;

[0021] Determine whether the seat actual status information is consistent with the seat expected status information. If not, adjust the seat status until the seat actual status information is consistent with the seat expected status information. If so, it indicates that the seat has been adjusted to a suitable state. The seat status can be adjusted manually by the user or automatically by the system. If the seat actual status information is inconsistent with the seat expected status information, the system will automatically or through a prompt adjust the seat status until the two are consistent. The adjustment method includes adjusting the seat height, angle or other related settings. This process can be achieved through automatic electric adjustment or guiding the user to manually adjust. This judgment logic ensures that the seat can be corrected to the expected state. This step improves the safety of seat use.

[0022] The seat status monitoring method in this embodiment obtains passenger information through a human-computer interaction interface, replacing the traditional method of relying on high-cost sensors for direct measurement, which significantly reduces the complexity of hardware and systems, thereby achieving a low-cost advantage; since the seat status information is generated by information input and rule generation, the system structure is simpler, and there is no need to integrate additional sophisticated multi-sensor modules, which also reduces maintenance and use costs, and the implementation method is simple and the user experience is good; at the same time, the method realizes dynamic adjustment of the seat status through real-time monitoring and feedback mechanism to form a closed-loop control, which not only effectively avoids performance fluctuations caused by aging of traditional sensors or environmental interference, but also ensures the reliability and stability of the long-term operation of the system, and is an overall detection prompt rather than a prompt for a single detection function; in addition, since the acquisition of core information relies on the human-computer interaction interface and internal data analysis of the system rather than direct measurement of external physical parameters, it is not easily affected by external environmental factors, has wide adaptability and reliability, and is suitable for stable use in various scenarios.

[0023] Optionally, the passenger information includes group information for user selection, where 40-105cm is a small group and 100-150cm is a large group. The user can directly select a predefined seat group; or the age, height, and weight information entered by the user can be input through keyboard input or voice recognition, and the system calculates the recommended seat status based on the input parameters. Allowing users to provide information in a variety of ways takes into account the convenience of users and the actual needs of different scenarios, making the system more flexible and adaptable.

[0024] Optionally, the passenger information also includes regional information. The system supports the entry of information from multiple regions (including China, Europe and the United States, etc.). The regional information can be actively selected by the user or automatically identified by the system (such as based on geographic location, device language or configuration, etc.). The system adjusts the calculation rules for the seat status according to the child safety seat standards in different regions. By introducing regional information, the system can automatically adapt to regional standards to ensure that the adjustment of the seat complies with local regulations and safety requirements, further improving product compliance and user experience.

[0025] Optionally, the human-machine interaction interface is an application software, which receives the passenger information through a communication connection and generates the seat status information; the human-machine interaction interface is implemented in the form of application software (such as a smartphone application or a dedicated APP in the vehicle system), and the user can operate it through a smart device (mobile phone, tablet or vehicle terminal); the user inputs or selects passenger information through the application software, including group information, age, height, weight and other data; the application software is connected to the control system of the child safety seat through wireless communication (such as Bluetooth, Wi-Fi or cellular network), and after the seat receives the passenger information transmitted by the application software, it generates the seat status information according to the built-in algorithm and adjusts the seat status. The application software generates the seat status information according to the input passenger information, and displays the result in real time on the human-machine interaction interface, prompting the user to confirm; the operation is convenient and the degree of intelligence is high.

[0026] Optionally, the human-computer interaction interface is a display operation interface on the seat, which is used to receive the passenger information and generate the seat status information; the display operation interface is integrated into the seat body, such as the seat back or side area, to facilitate user operation, and the display operation interface may include a touch screen, a button panel or other interactive forms to realize the entry and adjustment of passenger information; the display operation interface is used to directly input or select passenger information, such as group, age, height, weight, and generate and display the seat status information in real time based on the input information; by directly integrating the display operation interface into the seat, the operation process is simplified and the convenience is high.

[0027] Optionally, the human-computer interaction interface is a selection switch on the seat, and the user inputs the occupant information through the selection switch and generates the seat status information; the user inputs the group information through the selection switch, and the selection switch includes a mechanical or electronic device, such as a button, a touch button, a shift switch, a knob, etc.; the user enters the occupant information with simple physical operations by turning, toggling or pressing the selection switch, and the operation signal of the selection switch is transmitted to the seat control system, and the control system generates the occupant information according to the corresponding input. After receiving the input of the selection switch, the seat control system converts the occupant information into the corresponding seat status information according to the built-in rules or algorithms; the cost is low, the operation is simple and intuitive, and the convenience of use is improved.

[0028] Optionally, after the step of generating the expected seat status information, the step of presenting the expected seat status information on the human-computer interaction interface for the user to view is also included. After the system generates the expected seat status according to the input, the interface is automatically updated and displayed, and the user can view the recommended seat status at the first time; the expected seat status is displayed in a visual way, such as graphics, text, or animation, which is convenient for the user to understand intuitively; the expected seat status information is presented on the human-computer interaction interface, so that the user can clearly view the recommended status generated by the system. Through intuitive interface feedback, the user can quickly understand the matching degree between the current seat status and the recommended status, reducing the possibility of misoperation.

[0029] Optionally, the actual state information of the seat is obtained through a sensor, and the content detected by the sensor includes:

[0030] Detect the installation direction of the seat, obtain the forward or reverse installation status of the seat through a micro switch, Hall sensor or photoelectric switch, and determine whether it is consistent with the seat's expected status information. If not, adjust the installation direction until it is consistent; the sensor determines the forward or reverse installation status of the seat in real time, and compares the result with the seat's expected status information. If the detection result is inconsistent, prompt the user to adjust the seat direction, or correct the installation direction through the automatic rotation mechanism;

[0031] And / or, detect the use of the restraint system, obtain the actual use of the restraint system through a micro switch, pressure sensor or Hall sensor, and determine whether it is consistent with the expected state information of the seat. If not, adjust the restraint system until it is consistent; the sensor detects the actual use of the restraint system (such as seat belts, fixing buckles), determines whether the restraint system correctly fixes the child, and compares it with the expected state of the seat. If it is inconsistent, a warning prompt is issued, or the automatic adjustment module is triggered (such as locking the fixing buckle or tightening the seat belt); usually, children in small groups need to use the harness system that comes with the child safety seat, including a five-point seat belt and buckle. The standards of some countries also involve chest clips; child safety seats in small groups need to use the adult seat belts of the car, that is, three-point seat belts;

[0032] And / or, detect the height of the headrest, obtain the actual height of the headrest through the sensor, and determine whether it is consistent with the expected status information of the seat. If not, adjust the height of the headrest until it is consistent; detect the actual height of the headrest through a position sensor (such as an ultrasonic sensor, an infrared sensor) or a mechanical encoder, monitor in real time whether the headrest is in the recommended height range, and compare it with the expected status information of the seat. If they are inconsistent, adjust the height of the headrest through a motor drive or prompt the user to manually adjust the height of the headrest; usually, children in a small group are short in height and low in shoulder height, while children in a large group are tall in height and high in shoulder height. By detecting the actual height of the headrest and comparing the status or child information with the actual height of the headrest, the user is reminded;

[0033] And / or, detect the installation or release status of the components, determine the actual installation or release status of the components through sensors, and determine whether it is consistent with the status information of the seat. If not, adjust the status of the components until they are consistent; the components include support legs, fixing belts, latch devices or inner pads. Photoelectric sensors, pressure switches or Hall sensors are used to determine the actual installation or release status of the seat components, detect whether there are omissions or misoperations, and compare the results with the status information of the seat. If the status is inconsistent, the components are reinstalled or removed through prompts or electric devices; usually, during the use of small group child safety seats, support legs, Pull-up straps, large-group child safety seats do not need to install these components; the standards of some countries, such as the United States, require Latch to be installed in small groups, and in large groups, because they are switched to car seat belts, Latch needs to be removed and installed; many products also need to be matched with inner pads when used in small groups. Child safety seats with this function use sensors, such as micro switches or pressure sensors or photoelectric switches or Hall sensors built into the components or at specific positions, to determine whether the relevant components are installed normally and prompt the user. For example, in large groups, components that do not need to be installed will not be detected, and in small groups, if components that need to be installed are not installed normally, a warning will be given.

[0034] In this embodiment, sensors are used to perform all-round detection of the installation direction, restraint system, headrest height and component status to ensure that the actual status of the seat meets the recommended standards, thereby improving the overall safety of children riding in a vehicle. The detection and adjustment process is highly automated, and users do not need to tediously check the seat installation and adjustment status. Even if manual operation is required, the real-time feedback from the sensor can guide users to complete the correct adjustment, significantly reducing the difficulty of use. This monitoring method can implement complete user logic and comprehensively monitor whether the overall status of the seat is suitable for children.

[0035] Optionally, the method further comprises the steps of: if the actual state information of the seat is inconsistent with the expected state information of the seat, electrically controlling and adjusting the state of the seat until the actual state information of the seat is consistent with the expected state information of the seat;

[0036] The electric control to adjust the seat state includes:

[0037] The installation direction is adjusted by electric rotation according to the expected state information of the seat; the seat base and the vehicle body connection component are designed to be an electrically rotatable structure through the linkage of the motor and the rotating mechanism, and the sensor detects the actual direction of the seat in real time and feeds back the information to the control system; if the actual installation direction does not conform to the expected state information of the seat, the control system triggers the motor to rotate and adjust the base until the recommended forward or reverse installation angle is reached; the user can turn on the automatic mode, that is, when it is determined to be a reverse installation, when specific conditions are met (such as a child sitting or a user confirming), it automatically turns to the reverse direction; when it is determined to be a forward installation, when specific conditions are met (such as a child sitting or a user confirming), it automatically turns to the forward direction;

[0038] And / or, the headrest height is electrically adjusted according to the seat's expected state information; the headrest is connected to the guide rail system through a built-in motor, the motor drives the headrest to move up and down along the guide rail, the sensor detects the actual height information of the headrest, feeds it back to the control system, and compares it with the expected state information; if it is detected that the headrest height does not meet the recommended range, the control system controls the motor to drive the headrest to rise or fall until the headrest height is consistent with the expected state information; the user can turn on the automatic mode, and the child safety seat can automatically adjust to a headrest height suitable for children through the user input information (such as height, shoulder height or headrest gear selection) or the information obtained by the sensor (such as shoulder height, height or weight, etc.).

[0039] In this embodiment, the seat state is adjusted through electric control. The user does not need manual intervention, and the system can automatically complete complex adjustment tasks, which significantly improves the convenience of operation. The electric rotation and height adjustment are driven by real-time detection and feedback from sensors, and the system makes adjustments based on high-precision data to ensure that the adjustment results of the seat installation direction and headrest height meet the recommended standards.

[0040] Optionally, the method further comprises the steps of:

[0041] Determine whether the actual state information of the seat is consistent with the expected state information of the seat, and if not, issue a prompt or warning to the user to guide the user to make necessary adjustments;

[0042] The prompt or warning includes one or more of the following forms:

[0043] Advance reminders to guide users to adjust the seat to a state consistent with the expected state information of the seat before using it; remind users in advance through interfaces, sounds or visual signals to check and adjust the seat status before using it to ensure that it meets the expected standards, and the status information can be automatically displayed when starting the vehicle through smart applications or vehicle systems;

[0044] In-process reminders to prompt users to adjust the seat to a state consistent with the expected state information of the seat during use; during the use of the seat, if the actual state is detected to have changed, the system will issue a reminder at an appropriate time to require the user to adjust to the correct state, such as by sound alarms, vibration feedback or display screens to remind users to adjust the headrest, height or installation direction, etc.;

[0045] Post-event warnings are provided to alert users when the status is abnormal and not adjusted in time; if the user fails to adjust the seat in time and the seat status is still not consistent with the expected status information, the system will issue a warning to remind the user to make adjustments as soon as possible to avoid improper use that may affect child safety. The warning may be made through the in-vehicle voice system, mobile phone notifications, or warning lights on the seat itself.

[0046] In this embodiment, through a multi-level reminder mechanism such as advance reminders, in-process reminders and post-event warnings, the user can obtain feedback on the seat status at different time points, thereby reducing safety hazards caused by negligence or incorrect installation, especially in emergency situations. Post-event warnings can promptly remind users to take measures to prevent children from being injured due to incorrect seat status; the reminder and alarm functions make the use of the seat more intelligent, and the system provides comprehensive feedback to the user based on real-time monitoring data. Advance advance reminders and real-time in-event reminders can effectively reduce user erroneous operations caused by unfamiliarity or negligence, so that the seat is always in the safest state of use.

[0047] Optionally, the step of obtaining passenger information through a human-computer interaction interface and generating seat status information includes:

[0048] When the seat is installed for the first time, each time it is installed, each time it is powered on, when a passenger takes a seat, or when the vehicle starts to drive or is driving, passenger information is obtained through the human-computer interaction interface and the seat's expected status information is generated.

[0049] Specifically, first installation: When the seat is installed for the first time, the system obtains the basic information of the passenger (such as age, height, weight, etc.) through the human-computer interaction interface, and generates the seat's proper status information to ensure that the seat is suitable for the passenger's needs. Each installation: Each time the seat is reinstalled (such as vehicle transfer or seat shift), the system will re-acquire the passenger information and update the seat's proper status information. Each power-on: Each time the vehicle is powered on, the system automatically checks the passenger information and generates the seat's proper status information based on the latest data to ensure that the seat is in the correct state at each start. Passengers take their seats: When the passengers take their seats, the system obtains the passenger information through the human-computer interaction interface and generates the seat status that adapts to the current user. Vehicle driving starts: When the vehicle starts driving, the system will check the seat status again to ensure that the safety settings of the passengers are correct. During driving: During driving, the system will continuously monitor the passenger status and issue prompts or warnings to the user when necessary, reminding the user to adjust the seat status to ensure optimal safety.

[0050] In addition, as the occupants grow, the seat adaptation requirements will also change (for example, the height and weight of children change during growth, and the seat group is adjusted). The system will regularly send reminders to users based on the growth patterns of the occupants, prompting them to check and adjust the seat settings (such as adjusting the headrest height, installation direction, or changing to a suitable seat group). The system can also conduct one or more regular monitoring to evaluate whether the seat still meets the needs of the current occupants, and send reminders based on the monitoring results.

[0051] Optionally, combined Figure 2 As shown, the steps include:

[0052] Data collection of passenger information, including age, height, weight and historical usage behavior; basic passenger information, including age, height, weight and other basic data, is collected through sensors and input interfaces (such as touch screens, apps or vehicle-mounted systems). In addition, historical usage behaviors, such as seat adjustment frequency and usage habits (such as whether the headrest and seat angle are adjusted frequently), are also collected. These data provide a basis for algorithm analysis; the collected information is not limited to static data (such as height, weight, etc.), but also includes dynamic information (such as historical usage patterns, the number and type of seat adjustments, etc.), which fully reflects the needs and usage habits of passengers;

[0053] Based on the collected data, the algorithm is used to learn and analyze the growth patterns and usage patterns of passengers. Growth pattern analysis is based on the collected passenger data and uses machine learning algorithms to analyze the growth patterns of passengers. For example, as age and height increase, the adjustment requirements of seats will change. The algorithm can identify these patterns and predict future seat requirements. Usage pattern analysis identifies passengers' preferences and usage patterns for seats through analysis of historical usage behaviors. For example, some users may be accustomed to adjusting the height of the headrest or changing the angle of the seat. The system can learn and predict these preferences, thereby providing suggestions or adjustment prompts in advance.

[0054] The results of algorithm learning are combined with the input passenger information to generate the expected state information of the seat; the growth rules and usage patterns analyzed by the algorithm are combined with the basic information of the passenger to generate more personalized and dynamic expected state information of the seat, which includes but is not limited to: suitable seat group, optimal height of headrest and seat, installation direction, etc.; the expected state information of the seat is not only based on static data, but can also be dynamically adjusted to adapt to the actual changes in the needs of the passengers. For example, as the height of the child increases, the adjustment requirements of the seat will change, and the system will automatically adjust the configuration of the seat according to the prediction results of the algorithm;

[0055] Based on the generated expected status information, the prompt strategy is optimized, and the monitoring and prompt content of the seat status are dynamically adjusted; based on the generated expected seat status information, the system can dynamically optimize the prompt strategy. For example, if the system recognizes that a user is accustomed to adjusting the seat frequently, it will guide the user to adjust the seat status at critical moments through more frequent prompts or reminders; as the passengers grow and their usage patterns change, the prompt content will also be adjusted according to different needs. For example, during the growth of children, the system will provide more appropriate seat adjustment prompts based on changes in height and weight. For family users who drive frequently, the system will provide targeted suggestions based on historical usage behavior to ensure that the seat settings meet the optimal safety state.

[0056] In this embodiment, through data collection and algorithm learning, the system can provide accurate seat status information based on the growth patterns and usage patterns of the passengers. This personalized service can effectively improve the adaptability of the seats, ensuring that the seats meet the passengers' latest needs each time they are used, improving the user experience and having a high degree of intelligence.

[0057] An embodiment is as follows:

[0058] A child safety seat with forward and reverse installation detection, ISOFIX detection, support leg detection, seat entry and exit detection, buckle detection, car adult seat belt path detection, and headrest height detection functions; the child safety seat has a selection switch, which is a shift switch, and there are 2 gears according to the height, namely: 40-105cm and 100-150cm. Among them, 40-105cm is a small group, and 100-150cm is a large group. The small group requires reverse installation, normal installation of support legs, use of Harness system and detection of buckles, and low headrest height; the large group requires forward installation, retracting support legs, using and detecting car adult seat belts, and high headrest height. After the user selects the corresponding group through the selection switch, the child safety seat obtains the expected state of the seat, and obtains the expected state of the seat through the monitoring function, reports the expected state of the seat and the actual state of the seat through the human-computer interaction interface, and judges by comparing the expected state of the seat with the actual state of the seat, and prompts or alarms through the human-computer interaction interface. If the group adopts the forward installation, this is also a self-checking process. Through each child safety seat installation, or power-on, or child sitting, or driving, monitoring can also be performed regularly according to the growth of the child. In addition, the child safety seat of this embodiment can also have electric rotation and electric headrest height adjustment functions. The user can turn on the automatic steering function, and the child safety seat will automatically turn according to the expected state of the seat; the user enters the child information (such as height or shoulder height) or the headrest height gear selection information in the human-computer interaction interface, and turns on the automatic headrest height adjustment, the child safety seat will automatically adjust the headrest to a comfortable height.

[0059] Another embodiment of the present invention provides a child seat, which is used to implement the seat status monitoring method as described above.

[0060] The child seat in this embodiment obtains passenger information through a human-computer interaction interface, replacing the traditional method of relying on high-cost sensors for direct measurement, which significantly reduces the complexity of hardware and systems, thereby achieving a low-cost advantage; since the seat status information is generated by information input and rule generation, the system structure is simpler, and there is no need to integrate additional sophisticated multi-sensor modules, which also reduces maintenance and use costs, and the implementation method is simple and the user experience is good; at the same time, the method realizes dynamic adjustment of the seat status through real-time monitoring and feedback mechanisms to form a closed-loop control, which not only effectively avoids performance fluctuations caused by aging of traditional sensors or environmental interference, but also ensures the reliability and stability of the long-term operation of the system, and is an overall detection prompt rather than a prompt for a single detection function; in addition, since the acquisition of core information relies on the human-computer interaction interface and internal data analysis of the system rather than direct measurement of external physical parameters, it is not easily affected by external environmental factors, has wide adaptability and reliability, and is suitable for stable use in various scenarios.

[0061] Although the disclosure is disclosed as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the present invention.
