Description

Technical Field

[0001] This invention relates to the field of control system technology, and in particular to an adaptive airflow regulation seat ion purification ventilation system. Background Technology

[0002] With the rapid development of new energy vehicle technology, various types of motor vehicles are emerging in rapid succession, and people's demands for the comfort and safety of automobiles are also constantly increasing. As the temperature gradually rises, the perceived temperature inside the car also increases. Consequently, under direct sunlight, the seats and interior trim produce toxic gases such as carbon dioxide and methane, and PM2.5 levels also rise. This is not easily noticed by the occupants and can thus harm their health.

[0003] However, existing car seat technology still heavily relies on manual operation, presenting significant technological bottlenecks. On the one hand, purification and ventilation are "one-size-fits-all," lacking specificity and consuming excessive energy. Current in-vehicle purification and ventilation systems are mostly "uniformly controlled throughout the vehicle," meaning that regardless of whether a seat is occupied or whether the local air quality meets standards, the purification fans and purifiers are activated throughout the entire vehicle. On the other hand, it is difficult to balance ventilation intensity with user experience and efficiency. Existing fan speeds are fixed and lack fine-tuning. If a strong fan is used for rapid purification, passengers may feel uncomfortable from the cold air; if a weak fan is used, the purification speed is insufficient. Furthermore, it cannot flexibly adjust to the different needs of passengers in different seats. Summary of the Invention

[0004] This invention addresses the problems existing in the prior art by providing a seat ion purification and ventilation system with adaptive airflow regulation.

[0005] This application discloses an adaptive wind field control seat ion purification ventilation system, comprising: a occupancy sensor module, including a pressure sensor installed on the seat inside the vehicle for detecting whether someone is in the seat and transmitting the seat status information to an analysis and processing module; a gas quality detection module, including a PM2.5 concentration detector for transmitting the detected PM2.5 concentration to the analysis and processing module via a wireless network, with one gas quality detection module installed on each of the multiple seats; an ion purification module, including an ion purifier, a fan, an air outlet, and an air inlet for ventilating and purifying the air inside the vehicle, with one ion purification module installed on each of the multiple seats; an analysis and processing module, having data receiving, judgment, and transmission functions, determining whether a seat is occupied, unoccupied, and the gas quality level based on the received gas status information from the pressure sensor and PM2.5 concentration, judging the status of the ion purification module, and sending instructions to a seat embedded control module; and a seat embedded control module, including a control unit, controlling the usage status of the purification module by receiving instructions from the analysis and processing module.

[0006] Furthermore, the gas quality detection module acquires the gas state information of PM2.5 concentration around the seat every T time interval.

[0007] Furthermore, the gas quality detection module acquires the PM2.5 concentration information around each seat, and transmits this information to the analysis and processing module to determine whether the air quality is in one of four categories: excellent, good, poor, or very poor. If the PM2.5 concentration is less than or equal to... The rating is excellent if the PM2.5 concentration is greater than [a certain value]. and less than or equal to The air quality is deemed good if the PM2.5 concentration is greater than [a certain value]. and less than or equal to The condition is deemed poor if the PM2.5 concentration is greater than [a certain value]. It is judged to be of very poor quality.

[0008] The fan has four speed settings: hidden, level 1, level 2, and level 3. The airflow decreases gradually from level 3 to hidden, with the hidden setting having the lowest airflow, which is almost imperceptible to the human body. The fan can be controlled by the seat-embedded control module or manually, with manual control taking precedence over the seat-embedded control module.

[0009] The analysis and processing module transmits the judgment result to the seat embedded control module. If the air quality judgment result next to the seat is excellent, the control unit turns off the ion purifier; otherwise, the control unit turns on the ion purifier.

[0010] Furthermore, when the PM2.5 concentration around the seat is deemed unfavorable, both the fan and the ion purifier will be activated. Specifically, if the fan is not manually turned on by the passenger, it will automatically switch to a hidden position, and the ion purifier will be activated. If the fan has already been manually turned on by the passenger, it will be manually controlled, and only the ion purifier needs to be activated. If the fan has been manually turned on and then manually turned off by the passenger, it will automatically switch to a hidden position, and the ion purifier will be activated. When the PM2.5 concentration around the seat is deemed favorable, the ion purifier will be deactivated. Specifically, if the fan is not manually turned on by the passenger, it will be deactivated. If the fan has been turned on and not manually turned off by the passenger, it will be manually controlled and will not be automatically activated. If the fan has been manually turned on and then manually turned off by the passenger, it will not switch to a hidden position and will be deactivated directly.

[0011] Furthermore, if the PM2.5 concentration near a occupied seat is judged as extremely poor for a consecutive time, and the fan in the occupied seat is not at speed 3, the car's central control screen will display a prompt to increase the fan speed. After seeing this prompt, the driver can instruct the passenger to increase the fan speed in the corresponding occupied seat. If the fan speed is not increased after n consecutive prompts, the prompt will no longer appear.

[0012] Furthermore, if the PM2.5 concentration near an occupied seat is judged as extremely poor for *a* consecutive times, and all fans in occupied seats are at speed 3, a window for increasing fan speed will pop up on the car's central control screen. This window has two options: "Yes" and "No." If the window remains inactive for ten seconds, it will default to "No" and disappear. If the window pops up and the "No" option is selected *n* times consecutively, it will not pop up again. When the driver or passenger selects "Yes," all fans in unoccupied seats that are not at speed 3 will increase their speed by one level.

[0013] Furthermore, if the PM2.5 concentration near a person's seat is judged as extremely poor for a consecutive times, and all the fans in the seats are at level three, the car's center console receives control information from the analysis and processing module via wireless network. At the same time, the center console detects whether all the car's windows are fully open. If any window is not fully open, a prompt to open the window will pop up on the center screen. After seeing this prompt, the driver can open the window. If the driver does not operate the center console to open the window after n prompts, the prompt to open the window will no longer pop up.

[0014] Furthermore, if the PM2.5 concentration around all occupied seats is rated as poor or good, the fan in the unoccupied seat will be switched to hidden mode. If the PM2.5 concentration around an occupied seat is rated as extremely poor for *a* consecutive times, and the fan is turned up or the window is opened, and the PM2.5 concentration around all occupied seats is rated as good after this action, a reduced fan speed warning will pop up on the car's central control screen. The driver can then instruct the occupants to turn down the fan speed in the corresponding occupied seat or close the window. If the reduced fan speed warning is issued *n* times consecutively and the fan in the occupied seat is not turned down or the window is not closed, the reduced fan speed warning will no longer pop up.

[0015] Furthermore, the air outlet in the ion purification module is located on the front contact surface or the back of the seat; if the air outlet is located on the front contact surface of the seat, the air inlet is located on the back of the seat; if the air outlet is located on the back of the seat, the air inlet is located on the front contact surface of the seat; wherein the front contact surface of the seat is the side of the seat that contacts the back of the occupant; the fan is located inside the seat, the ion purifier is located inside the seat, the fan and the ion purifier are connected together, and the air outlet is located on the air outlet side of the fan, and the air inlet is located on the air inlet side of the fan; the air duct is located inside the seat to provide space for gas flow.

[0016] Furthermore, the occupancy sensor module, gas quality detection module, seat embedded control module, and ion purification module all have a network coordinator, which can transmit information status to the analysis and processing module or receive the information results analyzed by the analysis and processing module.

[0017] One or more technical solutions provided in this application have at least the following technical effects or advantages: 1. By using pressure sensors to detect occupied and unoccupied seats and gas quality detection modules to detect PM2.5 concentrations, accurate environmental information is obtained, providing a reliable basis for subsequent control and ensuring precise regulation for actual scenarios.

[0018] 2. The fan is designed with four wind speeds (from the hidden speed to the third speed). The hidden speed is so weak that it is almost imperceptible to the human body, which can maintain basic ventilation without disturbing sensitive people. The speed can be automatically adjusted according to needs, and manual priority control is also supported to meet personalized needs.

[0019] 3. Each seat is independently equipped with a purification and ventilation module, which can be individually adjusted according to the PM2.5 concentration and usage status of the gas next to different seats (for example, it can be activated when there is someone in the driver's seat and the PM2.5 is low, and turned off when there is no one in the back seat), avoiding a "one-size-fits-all" approach.

[0020] 4. The central control screen displays the fan speed and air quality for each seat, allowing users to intuitively understand the status. It also features seat-mounted fan speed adjustment components (such as knobs) for more direct manual operation. Manual control takes precedence over automatic control; users can manually adjust the fan speed at any time when they have specific needs (such as feeling the airflow is too strong), avoiding forced operation of the automatic system.

[0022] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0023] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] This invention designs an adaptive airflow field regulation seat ion purification and ventilation system, comprising: The occupancy sensor module includes a pressure sensor and a network coordinator installed on the seats inside the vehicle, used to detect whether there is a person in the seat and transmit the seat status information to the analysis and processing module; one occupancy sensor module is installed on each of the multiple seats.

[0026] The gas quality detection module includes a PM2.5 concentration detector and a network coordinator, which transmits the detected PM2.5 concentration to the analysis and processing module via a wireless network. One gas quality detection module is set up at each of the multiple seats.

[0027] The ion purification module includes a network coordinator, an ion purifier, a fan, an air outlet, an air inlet, and an air duct. It is used to ventilate and purify the air inside the vehicle, and one ion purification module is installed in each of the multiple seats.

[0028] Specifically, the ion purifier can be located between the air inlet and the fan, or between the air outlet and the fan.

[0029] Additionally, the air outlet in the ion purification module is located on the front or back of the seat, with the front contact surface being the side of the seat that contacts the back of the occupant. Specifically, when the air outlet is located on the front contact surface of the seat and the air inlet is located on the back of the seat, external air enters the seat from the back direction, and the air purified by ions is blown from the front contact surface of the seat towards the back of the human body. At this time, the ventilation mode of the seat is defined as the blowing type. When the air outlet is located at the back of the seat and the air inlet is located at the front contact surface of the seat, external air enters the seat from the front contact surface of the seat through the back of the human body, and the air purified by ions is blown out from the back of the seat. At this time, the ventilation mode of the seat is defined as suction type.

[0030] It should be noted that the front contact surface of the seat is designed to be breathable to facilitate airflow and prevent poor air circulation when the occupant leans against the seat.

[0031] It should be noted that when the seat ventilation method is suction type, the air duct between the seat air inlet and the ion purifier or fan can be fitted with an air bag, which guides the air flow. The air bag is a common structure in the existing technology and will not be described in detail here.

[0032] The analysis and processing module has data receiving, judgment, and transmission functions. Based on the received gas state information from the pressure sensor and PM2.5 concentration, it determines whether the seat is occupied or unoccupied, and the gas quality level. It also determines the status of the ion purification module and sends instructions to the seat embedded control module. Only one module can be configured for centralized processing of multiple status information. The seat-embedded control module, including a control unit and a network coordinator, controls the usage status of the purification modules by receiving instructions from the analysis and processing module. Only one module can be configured to control the usage status of multiple purification modules.

[0033] When there is only one seat-embedded control module, the seat-embedded control module can be located in the driver's seat.

[0034] It should be noted that the analysis and processing module can be located in the seat or in the center console of the vehicle; the specific location will not be described here.

[0035] For example, a typical family car usually has five seats: two front seats (driver's seat and passenger's seat) and three rear seats. In this case, a occupancy sensor module can be installed in each of these five seats.

[0036] The fan has four speed settings: hidden, level 1, level 2, and level 3. The airflow decreases gradually from level 3 to hidden, with the hidden setting having the lowest airflow, which is almost imperceptible to the human body. The fan can be controlled by the seat-embedded control module or manually, with manual control taking precedence over the seat-embedded control module.

[0037] It should be noted that the speed of each fan can be displayed on the central control screen and manually adjusted; at the same time, each seat can be equipped with a wind speed adjustment component (such as a speed adjustment knob) to allow passengers to adjust the fan speed in their respective seats.

[0038] It should be noted that the PM2.5 concentration level detected by the gas quality detection module next to each seat can be displayed on the central control screen.

[0039] The adaptive wind field regulation seat ion purification ventilation system obtains seat status information and gas status information of each seat through the analysis and processing module. After analysis and processing by the analysis and processing module, the control information is transmitted to the seat embedded control module, and the control unit controls the working status of the ion purification module.

[0040] The obtained seat status information from the pressure sensor is transmitted to the analysis and processing module to determine whether there is a person in the seat. If there is a person, the seat is defined as an occupied seat; if there is no person, the seat is defined as an unoccupied seat.

[0041] The gas quality detection module acquires the PM2.5 concentration around each seat, and transmits this information to the analysis and processing module to determine whether the air quality is excellent, good, poor, or very poor. If the PM2.5 concentration is less than or equal to... The rating is excellent if the PM2.5 concentration is greater than [a certain value]. and less than or equal to The air quality is deemed good if the PM2.5 concentration is greater than [a certain value]. and less than or equal to The condition is deemed poor if the PM2.5 concentration is greater than [a certain value]. It is judged to be of very poor quality.

[0042] The gas quality detection module acquires the PM2.5 concentration information of the air around the seat every T time interval and transmits the gas status information to the analysis and processing module.

[0043] It should be noted that time T can be 10 minutes or 15 minutes, and the specific time interval should be selected according to actual needs.

[0044] The analysis and processing module transmits the judgment result to the seat embedded control module. If the air quality judgment result next to the seat is excellent, the control unit turns off the ion purifier; otherwise, the control unit turns on the ion purifier.

[0045] In one embodiment, the analysis and processing module determines whether a seat is occupied or unoccupied and the gas quality level based on the received gas state information from the pressure sensor and PM2.5 concentration. It then determines the status of the ion purification module and sends a command to the seat-embedded control module. The seat-embedded control module controls the usage status of the purification module, including: When the PM2.5 concentration next to the seat is not rated as good, both the control fan and the ion purifier will be turned on. If the fan is not turned on by the passengers, it will automatically turn to the hidden position and the ion purifier will turn on. If the fan has been manually turned on by the passenger, the fan is now under manual control (it will not be automatically controlled), and you only need to keep the ion purifier on. If the fan has been manually turned on and then manually turned off by the passenger, the fan will automatically enter the hidden mode, keeping the ion purifier in the on state. When the PM2.5 concentration next to the seat is rated as excellent, the ion purifier will turn off. If the fan is not manually turned on by the occupants, the fan will be in the off state. If the fan has been turned on by the occupants (at speed 1, 2, or 3) and has not been manually turned off, the fan is in manual control mode and will not be automatically controlled. If the fan is manually turned off after being manually turned on by the passenger, the fan will not enter the hidden mode and will turn off directly.

[0046] For example, in a commonly used family car, if there is someone in the driver's seat and no one in the other seats, and the PM2.5 concentration around the driver's seat is determined to be poor, the fan will automatically turn to the hidden position if the driver or passenger does not actively turn it on. If the fan has been actively turned on by the driver or passenger and has not been manually turned off, the fan is in manual control mode and will not be automatically controlled. The driver or passenger can adjust the speed knob to control the fan speed. If the fan has been actively turned on by the driver or passenger and then manually turned off, the fan will automatically enter the hidden position.

[0047] In the second embodiment, the analysis and processing module determines whether a seat is occupied or unoccupied and the gas quality level based on the received gas state information from the pressure sensor and PM2.5 concentration. It then determines the status of the ion purification module and sends a command to the seat-embedded control module. The seat-embedded control module controls the usage status of the purification module, including: If the PM2.5 concentration near an occupied seat is rated as extremely poor for *a* consecutive times, and the fan in the occupied seat is not set to level 3, a prompt to increase the fan speed will appear on the car's central control screen. After seeing this prompt, the driver can instruct the passenger to increase the fan speed in the corresponding occupied seat (e.g., from level 2 to level 3). If the fan speed is not increased after *n* consecutive prompts, the prompt will no longer appear, and the count will be reset after restarting the vehicle.

[0048] It should be noted that the enhanced wind speed warning will disappear automatically after 10 seconds.

[0049] If the PM2.5 concentration near an occupied seat is rated as extremely poor for *a* consecutive times, and all fans in occupied seats are at speed 3, a window will pop up on the car's central control screen to select "Enhance Fan Speed." This window has two options: "Yes" and "No." If no action is taken within ten seconds, the "No" option will be selected by default, and the window will disappear. If the "No" option is selected in the "Enhance Fan Speed" window n times consecutively, the window will not pop up again. When the driver or a passenger selects "Yes," all fans in unoccupied seats that are not at speed 3 will be upgraded by one speed (e.g., the hidden fan speed will be upgraded to speed 1). The count will be reset after restarting the vehicle.

[0050] It should be noted that the values ​​of a and n are both positive integers. For example, the values ​​of a and n are both 3. The specific values ​​are selected according to the actual needs.

[0051] For example, in a commonly used family sedan, the front passenger seat is empty (the fan in the front passenger seat is in a hidden position), while the other seats are occupied. If the PM2.5 concentration near the occupied seats is rated as extremely poor for three consecutive times, and the fan in either the driver's seat or a rear seat is set to level two, a prompt to increase the fan speed will appear on the car's central control screen. After seeing this prompt, the driver will instruct the rear passengers to increase the fan speed in their rear seats (e.g., from level two to level three). If the driver and rear passengers do not increase the fan speed after three consecutive prompts, the prompt will no longer appear. When both the driver's and rear seat fans are at speed level 3, a boost fan speed option window will pop up on the car's central control screen. This window has two options: "Yes" and "No". If the boost fan speed option window is not used within ten seconds, the default option is "No", and the window will disappear. If the boost fan speed option window pops up and the "No" option is selected three times in a row, the window will not pop up again. When the driver or passenger selects the "Yes" option, the fan speed in the front passenger seat will increase by one level (the hidden fan speed will be increased to level 1).

[0052] It should be noted that in this example, the values ​​of a and n are positive integers of 3, and the time T is set to 10 minutes. In the third embodiment, the analysis and processing module determines whether a seat is occupied or unoccupied and the gas quality level based on the received gas state information from the pressure sensor and PM2.5 concentration, determines the status of the ion purification module, and sends a command to the seat embedded control module. The seat embedded control module controls the usage status of the purification module, including: If the PM2.5 concentration near a person's seat is judged as extremely poor for a consecutive times, and all the fans in the seats are at level three, the car's center console receives control information from the analysis and processing module via wireless network. At the same time, the center console detects whether all the car's windows are fully open. If any window is not fully open, a prompt to open the window will pop up on the center screen. After seeing the prompt, the driver can open the window. If the driver does not operate the center console to open the window after n prompts, the prompt to open the window will no longer pop up, and the count will be reset after restarting the vehicle.

[0053] It should be noted that the window opening prompt disappears automatically after 10 seconds.

[0054] It should be noted that the values ​​of a and n are both positive integers. For example, the values ​​of a and n are both 3. The specific values ​​are selected according to the actual needs.

[0055] If the PM2.5 concentration around all occupied seats is rated as poor or good, then the fan in the unoccupied seat will be switched to the hidden mode.

[0056] If the PM2.5 concentration near an occupied seat is rated as "extremely poor" for "a" consecutive times, and the fan is turned up or the window is opened, and after this action, the PM2.5 concentration near all occupied seats is rated as "good," then the car's central control screen will display a prompt to reduce the fan speed. After seeing this prompt, the driver can instruct the occupants to turn down the fan speed in the corresponding occupied seat (e.g., from level two to level one) or close the window. If the fan speed is reduced after "n" consecutive prompts and the fan speed is not reduced or the window is not closed, the prompt will no longer appear, and the count will be reset after restarting the vehicle.

[0057] For example, in a commonly used family sedan, the front passenger seat is empty, but the other seats are occupied. If the PM2.5 concentration near the occupied seats is rated as extremely poor for three consecutive times, and all the fans in the seats are set to level three, the car's center console receives control information from the analysis and processing module via a wireless network. At the same time, the center console detects whether all the car's windows are fully open. If any window is half-open, a prompt to open the window will pop up on the center screen. After seeing this prompt, the driver can fully open the window. If the driver does not open the window after three prompts, the prompt will no longer pop up.

[0058] If the PM2.5 concentration near an occupied seat is rated as "extremely poor" three times consecutively, and the fan is turned up or the windows are opened, but the PM2.5 concentration near the driver's seat and rear seats is rated as "good" after this action, a prompt to reduce the fan speed will appear on the car's central control screen. After seeing this prompt, the driver can ask the rear passengers to turn down the fan speed in the rear seats, from level two to level one. If the fan speed is not reduced after three consecutive prompts, the prompt will no longer appear.

[0059] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages: 1. By using pressure sensors to detect occupied and unoccupied seats and gas quality detection modules to detect PM2.5 concentrations, accurate environmental information is obtained, providing a reliable basis for subsequent control and ensuring precise regulation for actual scenarios.

[0060] 2. The fan is designed with four wind speeds (from the hidden speed to the third speed). The hidden speed is so weak that it is almost imperceptible to the human body, which can maintain basic ventilation without disturbing sensitive people. The speed can be automatically adjusted according to needs, and manual priority control is also supported to meet personalized needs.

[0061] 3. Each seat is independently equipped with a purification and ventilation module, which can be individually adjusted according to the PM2.5 concentration and usage status of the gas next to different seats (for example, it can be activated when there is someone in the driver's seat and the PM2.5 is low, and turned off when there is no one in the back seat), avoiding a "one-size-fits-all" approach.

[0062] 4. The central control screen displays the fan speed and air quality for each seat, allowing users to intuitively understand the status. It also features seat-mounted fan speed adjustment components (such as knobs) for more direct manual operation. Manual control takes precedence over automatic control; users can manually adjust the fan speed at any time when they have specific needs (such as feeling the airflow is too strong), avoiding forced operation of the automatic system.

[0063] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
