A method for monitoring the condition of a car seat and a child car seat Technical Field

[0001] This invention relates to the field of automotive safety products technology, and more specifically, to a method for monitoring the condition of a car seat and a child car seat. Background Technology

[0002] Child safety seats are categorized based on a child's age, height, and weight, and generally include multiple groups. When using a child safety seat, it's necessary to switch to the appropriate seat position based on the child's age, height, and weight. Different countries may have different standards for classifying child safety seats, some considering height, others weight. However, current technologies that use sensors to identify a child's height or weight suffer from high costs, unstable performance, and susceptibility to environmental factors. Summary of the Invention

[0003] To address at least one of the aforementioned problems, the present invention first provides a seat status monitoring method, comprising the steps of: acquiring occupant information through a human-computer interaction interface and generating expected seat status information; acquiring actual seat status information based on the content corresponding to the expected seat status information; determining whether the actual seat status information is consistent with the expected seat status information; if not, adjusting the seat status until the actual seat status information is consistent with the expected seat status information.

[0004] Optionally, the passenger information includes group information selectable by the user, or age, height, and weight information input by the user; the passenger information also includes region information.

[0005] Optionally, the human-computer interaction interface is application software, which receives the passenger information via a communication connection and generates the required status information of the seat; and / or, the human-computer interaction interface is a display operation interface on the seat, which receives the passenger information and generates the required status information of the seat; and / or, the human-computer interaction interface is a selection switch on the seat, through which the user inputs the passenger information and generates the required status information of the seat.

[0006] Optionally, after the step of generating the required status information of the seat, the method further includes the step of presenting the required status information of the seat on the human-computer interaction interface for the user to view.

[0007] Optionally, the method further includes the step of: determining whether the actual state information of the seat is consistent with the expected state information of the seat; if they are inconsistent, issuing a prompt or alarm to the user; the prompt or alarm includes one or more of the following forms: advance reminder, to guide the user to adjust to a state consistent with the expected state information of the seat before using the seat; in-process reminder, to promptly remind the user to adjust to a state consistent with the expected state information of the seat during the use of the seat; and post-process warning, to warn the user when the state is abnormal and not adjusted in time.

[0008] Optionally, the step of obtaining passenger information and generating the required seat status information through the human-computer interaction interface includes: obtaining passenger information and generating the required seat status information through the human-computer interaction interface during the initial installation of the seat, each installation, each power-on, passenger seating, vehicle start-up, or during driving.

[0009] Optionally, the method includes the following steps: collecting passenger information, including age, height, weight, and historical usage behavior; based on the collected data, analyzing the passenger's growth patterns and usage patterns through algorithm learning; combining the algorithm learning results with the input passenger information to generate the seat's expected status information; and optimizing the prompting strategy and dynamically adjusting the monitoring and prompting content of the seat status according to the generated expected status information.

[0010] Optionally, the actual state information of the seat is acquired through sensors. The sensors detect the following: the installation direction of the seat, acquiring the forward or reverse installation state of the seat through a microswitch, Hall sensor, or photoelectric switch, and determining whether it is consistent with the expected state information of the seat; if not, adjusting the installation direction until it is consistent; and / or, the usage status of the restraint system, acquiring the actual usage status of the restraint system through a microswitch, pressure sensor, or Hall sensor, and determining whether it is consistent with the expected state information of the seat; if not, adjusting the restraint system until it is consistent; and / or, the headrest height, acquiring the actual height of the headrest through a sensor, and determining whether it is consistent with the expected state information of the seat; if not, adjusting the headrest height until it is consistent; and / or, the installation or removal status of components, determining the actual installation or removal status of components through sensors, and determining whether it is consistent with the expected state information of the seat; if not, adjusting the status of the components until it is consistent.

[0011] Optionally, the method further includes the step of: if the actual state information of the seat is inconsistent with the expected state information of the seat, then electrically controlling the adjustment of the seat state until the actual state information of the seat is consistent with the expected state information of the seat; the electric control adjustment of the seat state includes: electrically rotating and adjusting the installation direction according to the expected state information of the seat; and / or, the electric adjustment of the headrest height according to the expected state information of the seat.

[0012] Compared to existing technologies, the seat status monitoring method in this invention acquires occupant information through a human-computer interaction interface, replacing the traditional method that relies on direct measurement using high-cost sensors. This significantly reduces hardware and system complexity, achieving a low-cost advantage. Because it uses information input and rule generation to generate the required seat status information, the system structure is simplified, eliminating the need for additional sophisticated multi-sensor modules and reducing maintenance and usage costs. The implementation is simple, and the user experience is excellent. Furthermore, this method achieves dynamic adjustment of the seat status through real-time monitoring and feedback mechanisms, forming a closed-loop control. This effectively avoids performance fluctuations caused by traditional sensor aging or environmental interference, ensuring the long-term reliability and stability of the system. The detection and prompting are holistic, rather than based on individual detection functions. Additionally, since the core information acquisition relies on the human-computer interaction interface and internal system data analysis, rather than direct measurement of external physical parameters, it is less susceptible to external environmental factors, possessing broad adaptability and reliability, and is suitable for stable use in various scenarios.

[0013] In addition, the present invention provides a child seat for implementing the seat status monitoring method described above.

[0014] Compared to existing technologies, the child car seat described in this invention and the aforementioned car seat status monitoring method have the same advantages over existing technologies, which will not be repeated here. Attached Figure Description

[0015] Figure 1 is a flowchart of the seat status monitoring method according to an embodiment of the present invention;

[0016] Figure 2 is a flowchart of the seat status monitoring method according to an embodiment of the present invention. Detailed Implementation

[0017] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0018] This invention provides a seat status monitoring method, as shown in Figure 1, including the following steps:

[0019] The system obtains passenger information through a human-computer interaction interface and generates the required seat status information. Basic passenger information, such as age, height, and weight, is obtained via a human-computer interaction interface (e.g., touchscreen, voice recognition, or other input devices). This information can be input by the user, and the system will generate corresponding seat status information based on this information. For example, for child safety seats, the required seat status information may include the appropriate seat group, seat height, and seat cushion position. This step generates the required seat status information based on accurate passenger information, ensuring that the seat can be personalized according to the passenger's characteristics each time it is used, improving comfort and safety at a low cost.

[0020] Based on the required status information of the seat, the actual status information of the seat is obtained. The actual status information of the seat is acquired in real time through sensors built into the seat (such as pressure sensors, position sensors, or other status detection modules). These sensors can detect the actual height, position, angle, locking status, etc., ensuring real-time monitoring of the seat's status. The actual status information of the seat can also be viewed and obtained by the user. By monitoring the seat's status in real time, it is possible to promptly detect whether the seat has a positional deviation or is not adjusted to a suitable state, avoiding improper human operation or seat adjustment failures, thus improving safety.

[0021] The system determines whether the actual seat status information matches the expected seat status information. If not, it adjusts the seat status until the actual status information matches the expected status information. If the actual status information matches the expected status information, the seat has been adjusted to a suitable state. Adjusting the seat status can be done manually by the user or automatically by the system. If the actual seat status information does not match the expected status information, the system will automatically adjust the seat status or provide prompts until they match. Adjustment methods include adjusting the seat height, angle, or other related settings. This process can be achieved through automatic electric adjustment or by guiding the user to manually adjust. This judgment logic ensures that the seat can be corrected to its intended state, improving the safety of seat use.

[0022] The seat status monitoring method in this embodiment acquires occupant information through a human-machine interface, replacing the traditional method that relies on direct measurement using high-cost sensors. This significantly reduces hardware and system complexity, achieving a low-cost advantage. Since the method generates the required seat status information through information input and rule generation, the system structure is simplified, eliminating the need for additional sophisticated multi-sensor modules and reducing maintenance and usage costs. The implementation is simple, and the user experience is excellent. Furthermore, this method achieves dynamic adjustment of the seat status through real-time monitoring and feedback mechanisms, forming a closed-loop control. This effectively avoids performance fluctuations caused by traditional sensor aging or environmental interference, ensuring the long-term reliability and stability of the system. The detection and prompting are holistic, rather than based on individual detection functions. Additionally, because the core information acquisition relies on the human-machine interface and internal system data analysis, rather than direct measurement of external physical parameters, it is less susceptible to external environmental factors, possessing broad 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 the smaller group and 100-150cm is the larger group. Users can directly select a predefined seat group; or the system can calculate the recommended seat position based on the user's age, height, and weight information, entered via keyboard input or voice recognition. This allows users to provide information in multiple ways, balancing user convenience with 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 input of information from multiple regions (including China, Europe and the United States). The regional information can be actively selected by the user or automatically identified by the system (e.g., based on geographical location, device language, or configuration). The system adjusts its calculation rules for seat status according to the child safety seat standards of different regions. By introducing regional information, the system can automatically adapt to regional standards, ensuring that the seat adjustment complies with local regulations and safety requirements, further improving product compliance and user experience.

[0025] Optionally, the human-machine interface is application software. This application software receives the occupant information via a communication connection and generates the required status information for the seat. The human-machine interface is implemented as application software (such as a smartphone application or a dedicated app in a vehicle system), and users can operate it through smart devices (phones, tablets, or in-vehicle terminals). Users input or select occupant information through the application software, including group information, age, height, weight, and other data. The application software connects to the child safety seat's control system via wireless communication (such as Bluetooth, Wi-Fi, or cellular network). After receiving the occupant information transmitted by the application software, the seat generates the required status information based on a built-in algorithm and adjusts the seat status. The application software generates the required status information for the seat based on the input occupant information and displays the result on the human-machine interface in real time, prompting the user for confirmation. The operation is convenient and highly intelligent.

[0026] Optionally, the human-computer interaction interface is a display operation interface on the seat. The display operation interface is used to receive the passenger information and generate the required status information of the seat. The display operation interface is integrated into the main body of the seat, such as the seat back or side area, for convenient user operation. The display operation interface may include a touch screen, button panel, or other interactive forms to realize the input and adjustment of passenger information. The display operation interface is used to directly input or select passenger information, such as group, age, height, and weight, and generate and display the required status information of the seat 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-machine interface is a selection switch on the seat. The user inputs the occupant information through the selection switch, and the system generates the required seat status information. The user inputs group information through the selection switch, which includes mechanical or electronic devices such as buttons, touch buttons, toggle switches, and knobs. The user inputs occupant information through simple physical operations by rotating, toggling, or pressing the selection switch. The operation signal of the selection switch is transmitted to the seat control system, which generates occupant information based on the corresponding input. After receiving the input from the selection switch, the seat control system converts the occupant information into the corresponding required seat status information according to built-in rules or algorithms. This method is low-cost, simple and intuitive to operate, and improves ease of use.

[0028] Optionally, after the step of generating the required seat status information, the method further includes the step of displaying the required seat status information on the human-computer interaction interface for user viewing. When the system generates the required seat status based on input, the interface automatically updates and displays it, allowing the user to view the recommended seat status immediately. The required seat status is displayed visually, such as through graphics, text, or animation, facilitating intuitive understanding by the user. Displaying the required seat status information on the human-computer interaction interface allows the user to 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 status information of the seat is acquired through sensors, and the content detected by the sensors includes:

[0030] The system detects the installation direction of the seat by acquiring the forward or reverse installation status of the seat through microswitches, Hall sensors, or photoelectric switches, and determines whether it is consistent with the seat's expected status information. If not, the installation direction is adjusted 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, the user is prompted to adjust the seat direction, or the installation direction is corrected through an automatic rotation mechanism.

[0031] And / or, detect the usage of the restraint system, obtain the actual usage of the restraint system through microswitches, pressure sensors, or Hall sensors, and determine whether it is consistent with the seat's expected status information. If not, adjust the restraint system until it is consistent. Sensors detect the actual usage of the restraint system (such as seat belts, buckles), determine whether the restraint system correctly secures the child, and compare it with the seat's expected status. If they are inconsistent, issue a warning or trigger the automatic adjustment module (such as locking buckles or tightening seat belts). Generally, children in the small group need to use the Harness system that comes with the child safety seat, including a five-point harness and buckle. In some countries' standards, a chest clip is also involved. Children in the small group need to use the car's adult seat belt, i.e., a three-point seat belt.

[0032] And / or, detect the headrest height, obtain the actual height of the headrest through sensors, and determine whether it is consistent with the seat's expected status information. If not, adjust the headrest height until it is consistent. Alternatively, use position sensors (such as ultrasonic sensors or infrared sensors) or mechanical encoders to detect the actual height of the headrest, monitor in real time whether the headrest is within the recommended height range, and compare it with the seat's expected status information. If they are inconsistent, drive the motor or prompt the user to manually adjust the headrest height. Typically, children in smaller groups are shorter and have lower shoulder heights, while children in larger groups are taller and have higher shoulder heights. By detecting the actual headrest height and comparing it with the corresponding status or child information, remind the user.

[0033] And / or, detect the installation or removal status of components, determine the actual installation or removal status of components through sensors, and determine whether it is consistent with the seat's expected status information. If not, adjust the status of the components until they are consistent. Components include support legs, fixing straps, latches, or inner pads. Use photoelectric sensors, pressure switches, or Hall sensors to determine the actual installation or removal status of seat components, detect whether there are omissions or misoperations, compare the results with the seat's expected status information, and if the status is inconsistent, complete the reinstallation or removal of components through prompts or electric devices. Under normal circumstances, during the use of group-level child safety seats, it is necessary to install support legs, For child safety seats in the larger class, the upper tether strap is not required. In some countries, such as the United States, LATCH is required for the smaller class, but needs to be removed for the larger class due to the switch to a car seatbelt. Many products also require an inner liner for the smaller class. Child safety seats with this function use sensors, such as microswitches, pressure sensors, photoelectric switches, or Hall effect sensors built into components or in specific locations, to determine if relevant components are installed correctly and alert the user. For example, in the larger class, components that do not require installation are not checked, while in the smaller class, if required components are not installed correctly, a warning is issued.

[0034] In this embodiment, sensors are used to comprehensively detect the installation direction, restraint system, headrest height, and component status to ensure that the actual condition of the seat meets the recommended standards, thereby improving the overall safety of children riding in cars. The detection and adjustment process is highly automated, eliminating the need for users to tediously check the seat installation and adjustment status. Even if manual operation is required, the real-time feedback from the sensors can guide users to complete the correct adjustment, significantly reducing the difficulty of use. This monitoring method can realize complete user logic and comprehensively monitor whether the overall condition of the seat is suitable for children.

[0035] Optionally, the method further includes the step of: if the actual state information of the seat is inconsistent with the expected state information of the seat, then the seat state is adjusted by electric control until the actual state information of the seat is consistent with the expected state information of the seat;

[0036] The electrically controlled adjustment of the seat status includes:

[0037] The installation direction is electrically adjusted by rotating the seat according to the required seat status information. Through the linkage of the motor and the rotating mechanism, the connection between the seat base and the vehicle body is designed as an electrically rotatable structure. Sensors detect the actual direction of the seat in real time and feed the information back to the control system. If the actual installation direction does not conform to the required seat status information, 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 activate the automatic mode, that is, when it is determined to be reverse installation, it will automatically turn to the reverse direction when a specific condition is met (such as a child sitting down or user confirmation), and when it is determined to be forward installation, it will automatically turn to the forward direction when a specific condition is met (such as a child sitting down or user confirmation).

[0038] And / or, the headrest height is electrically adjusted according to the seat's intended status information; the headrest is connected to a guide rail system via 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 and feeds it back to the control system, which compares it with the intended status information. If the headrest height is detected to be inconsistent with 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 intended status information; the user can activate the automatic mode, and the child safety seat can automatically adjust to a headrest height suitable for the child by acquiring user input information (such as height, shoulder height, or headrest position selection) or by acquiring information from sensors (such as shoulder height, height, or weight).

[0039] In this embodiment, the seat state is adjusted by electric control, eliminating the need for manual intervention by the user. The system can automatically complete complex adjustment tasks, significantly improving the convenience of operation. The electric rotation and height adjustment are driven by real-time detection and feedback from sensors. 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 steps also include:

[0041] Determine whether the actual status information of the seat is consistent with the expected status information of the seat. If they are inconsistent, issue a prompt or alarm to the user to guide the user to make necessary adjustments.

[0042] The prompts or alarms include one or more of the following forms:

[0043] Advance reminders guide users to adjust the seat to a state consistent with the required seat status information before use; before using the seat, users are reminded in advance to check and adjust the seat status through interface, sound or visual signals to ensure that it meets the required standards, and the status information can be automatically displayed when the vehicle is started through smart applications or in-vehicle systems;

[0044] The system provides timely prompts to remind users to adjust the seat to a state consistent with its intended status during use. If a change in the actual state is detected during seat use, the system will issue a prompt at an appropriate time, requiring the user to adjust to the correct state, such as through sound alarms, vibration feedback, or display screen reminders to adjust the headrest, height, or installation direction.

[0045] The system provides a warning after the fact, alerting the user if the seat is not adjusted in time due to abnormal conditions. If the user does not 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 affecting the child's safety. The warning may be issued through the in-vehicle voice system, mobile phone notification, or warning light on the seat itself.

[0046] In this embodiment, through a multi-layered notification mechanism including pre-installation reminders, in-process prompts, and post-installation warnings, users can receive feedback on the seat status at different times, thereby reducing safety hazards caused by negligence or incorrect installation. Especially in emergency situations, post-installation warnings can promptly remind users to take measures to prevent children from being injured due to incorrect seat status. The prompting and alarm functions make the use of the seat more intelligent. The system provides comprehensive feedback to users based on real-time monitoring data. Advance reminders and real-time prompts can effectively reduce errors caused by user unfamiliarity or negligence, ensuring that the seat is always in the safest use condition.

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

[0048] During the initial installation of the seat, each installation, each power-on, when passengers sit down, and when the vehicle starts or is in motion, passenger information is obtained through the human-machine interface, and the required seat status information is generated.

[0049] Specifically, the system operates as follows: Initial Installation: Upon initial installation, the system obtains basic occupant information (such as age, height, and weight) through the human-machine interface and generates the appropriate seat status information to ensure the seat suits the occupant's needs. Each Installation: Each time the seat is reinstalled (e.g., during vehicle transfer or seat relocation), the system re-obtains occupant information and updates the seat's status information. Each Power-On: Each time the vehicle is powered on, the system automatically checks occupant information and generates the appropriate seat status information based on the latest data, ensuring the seat is in the correct state upon startup. Occupant Seating: When an occupant sits down, the system obtains occupant information through the human-machine interface and generates a seat status adapted to the current user. Vehicle Start-up: When vehicle operation begins, the system checks the seat status again to ensure the occupant's safety settings are correct. During Operation: During operation, the system continuously monitors the occupant's status and, if necessary, issues prompts or warnings to the user, reminding them to adjust the seat status for optimal safety.

[0050] Furthermore, as passengers grow, the seat's adaptation needs will change (for example, changes in height and weight during a child's growth require adjustments to the seat group). The system will periodically send reminders to users based on their growth patterns, prompting them to check and adjust the seat settings (such as adjusting headrest height, installation direction, or changing to a suitable seat group). The system can also perform one or more periodic monitoring sessions to assess whether the seat still meets the current passenger's needs and send reminders based on the monitoring results.

[0051] Optionally, referring to Figure 2, the steps include:

[0052] Passenger information is collected, including age, height, weight, and historical usage behavior. Basic passenger information, such as age, height, and weight, is collected through sensors and input interfaces (e.g., touchscreen, app, or in-vehicle system). Historical usage behavior is also collected, such as seat adjustment frequency and usage habits (e.g., whether headrests or seat angles are frequently adjusted). This data provides the basis for algorithm analysis. The collected information is not limited to static data (e.g., height, weight) but also includes dynamic information (e.g., historical usage patterns, frequency and type of seat adjustments), comprehensively reflecting the passenger's needs and usage habits.

[0053] Based on the collected data, algorithms are used to learn and analyze the growth patterns and usage patterns of passengers. Growth pattern analysis uses machine learning algorithms to analyze the growth patterns of passengers based on the collected passenger data. For example, as age and height increase, seat adjustment needs will change. The algorithm can identify these patterns and predict future seat needs. Usage pattern analysis identifies passengers' preferences and usage patterns for seats by analyzing historical usage behavior. 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 algorithm's learning results are combined with the input occupant information to generate the required seat status information. Furthermore, the algorithm's analysis of growth patterns and usage patterns is combined with the occupant's basic information to generate more personalized and dynamic seat status information. This information includes, but is not limited to, the appropriate seat group, optimal headrest and seat height, and installation orientation. The seat status information is not only based on static data but can also be dynamically adjusted to adapt to changes in the occupant's actual needs. For example, as a child's height increases, the seat adjustment requirements will change, and the system will automatically adjust the seat configuration based on the algorithm's predictions.

[0055] Based on the generated expected seat status information, the system optimizes the prompting strategy and dynamically adjusts the monitoring and prompting content of the seat status. For example, if the system detects that a user frequently adjusts the seat, it will guide the user to adjust the seat status at critical moments through more frequent prompts or reminders. As passengers grow and their usage patterns change, the prompting content will also be adjusted according to different needs. For example, during a child's growth, the system will provide more suitable seat adjustment prompts based on changes in height and weight. For family users who frequently drive, the system will provide targeted suggestions based on historical usage behavior to ensure that the seat settings meet the optimal safety requirements.

[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 passengers. This personalized service can effectively improve the adaptability of the seat, ensuring that the seat meets the latest needs of passengers every time it is used, thereby enhancing the user experience and demonstrating a high degree of intelligence.

[0057] One example is as follows:

[0058] A child safety seat with functions of forward and reverse installation detection, ISOFIX detection, support leg detection, seat occupancy and departure detection, buckle detection, car adult seat belt path detection, and headrest height detection; there is a selection switch on the child safety seat, and the selection switch is a toggle switch with 2 gears according to height, namely: 40 - 105 cm, 100 - 150 cm. Among them, 40 - 105 cm is the small group, and 100 - 150 cm is the large group. The small group requires reverse installation, normal installation of the support leg, use of the Harness system and detection of the buckle, and a low headrest height; the large group requires forward installation, retraction of the support leg, use of the car adult seat belt and its detection, and a high headrest height. After the user selects the corresponding group through the selection switch, the child safety seat obtains the required state of the seat, and obtains the required state of the seat through the monitoring function. The required state of the seat and the actual state of the seat are reported through the human - machine interaction interface, and a judgment is made by comparing the required state of the seat with the actual state of the seat. A prompt or alarm is given through the human - machine interaction interface. For example, if the small group takes forward installation, this is also a self - inspection process. Monitoring is carried out every time the child safety seat is installed, or powered on, or the child is seated, or the vehicle starts, and it can also be monitored regularly according to the growth of the child. In addition, the child safety seat in this embodiment can also have functions of electric rotation and electric headrest height adjustment. The user can turn on the automatic steering function, and the child safety seat will automatically turn according to the required state of the seat; when the user inputs child information (such as height or shoulder height) or headrest height gear selection information on the human - machine 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 for implementing the seat state monitoring method as described above.

[0060] In the child seat of this embodiment, the information of the occupant is obtained through the human - machine interaction interface, replacing the traditional way of directly measuring with high - cost sensors, significantly reducing the hardware and system complexity, thus achieving a low - cost advantage; since the method of information input and rule generation is used to generate the required seat state information, the system structure is more simplified, without the need to additionally integrate precise multi - sensor modules, and the maintenance and use costs are also reduced. The implementation method is simple and the user experience is good; at the same time, through the real - time monitoring and feedback mechanism, the dynamic adjustment of the seat state is realized, forming a closed - loop control. This not only effectively avoids the performance fluctuation problems caused by the aging of traditional sensors or environmental interference, but also ensures the reliability and stability of the long - term operation of the system, and it is a holistic detection prompt rather than a prompt for a single detection function; in addition, since the acquisition of core information depends on the human - machine interaction interface and internal data analysis of the system, rather than the 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] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
