[0002] Currently, cars, SUVs, multi-purpose vehicles, off-road vehicles, buses, and motorhomes bring numerous conveniences to people's lives, work, and studies, occupying an important position in people's travel. As people's living standards improve, vehicles are gradually evolving into intelligent private spaces that integrate entertainment, and people's requirements for air quality in the passenger cabin are also increasing.

[0003] In related technologies, the proportion of vehicle internal air circulation is relatively low, resulting in higher vehicle energy consumption, which is not conducive to improving the vehicle's range. Summary of the Invention

Detailed Implementation

[0071] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this application. It should be understood that the specific embodiments described herein are merely illustrative and do not limit the scope of protection of this application.

[0072] 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 application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0073] like Figure 1 As shown in the embodiment of this application, a vehicle 10 is also provided, including a body assembly 11 and an on-board air conditioning device 12. The body assembly 11 is provided with a passenger compartment 101, and the on-board air conditioning device 12 is disposed on the body assembly 11 for supplying temperature-regulating gas to the passenger compartment 101.

[0074] And such Figures 2 to 5As shown, the vehicle air conditioning system 12 includes a gas detection device 100, an air conditioning unit 200, an adsorption device 300, and a control device. The gas detection device 100 is used to detect the content of a target gas in the passenger compartment 101. The air conditioning unit 200 includes a heat exchange component 210 and an air supply component 220. The heat exchange component 210 includes a first air intake 211 and a first air outlet 212 communicating with the passenger compartment 101. The air supply component 220 includes a second air outlet, a second air intake 222, and a third air intake 223. The second air outlet communicates with the first air intake 211, the second air intake 222 communicates with the passenger compartment 101, and the third air intake 223 communicates with the outside of the vehicle 10. The adsorption device 300 includes an adsorption outlet section 302 and an adsorption intake section. The adsorption device 300 can adsorb at least one of the target gas inside the passenger compartment 101 and the target gas entering the air conditioning unit 200 via the adsorption intake section. The adsorption outlet section 302 is connected to at least one of the air conditioning unit 200 and the passenger compartment 101. A control device is communicatively connected to the gas detection device 100, the air conditioning unit 200, and the adsorption device 300. The control device includes a memory and a processor. The memory stores a computer program, and the processor executes the computer program to implement the following control method for the vehicle air conditioning equipment 12, including:

[0075] The vehicle's air conditioning system is put into economy mode, and in economy mode, the percentage of in-vehicle gas used by the vehicle's air conditioning system to adjust the temperature is greater than or equal to the set value.

[0076] The content of target gases in the crew cabin is obtained. The target gases include at least one of carbon dioxide, water vapor, and harmful gases.

[0077] When the target gas content in the passenger compartment is greater than or equal to the first threshold, the adsorption device is controlled to adsorb at least one of the target gas in the passenger compartment and the target gas entering the passenger compartment, in order to maintain the economic mode.

[0078] During vehicle use, the temperature inside the passenger compartment is adjusted by the vehicle-mounted air conditioning system in any of the above embodiments to improve the riding experience. This system connects to the passenger compartment via a first air outlet and to a first air inlet, delivering gas to the heat exchange components for temperature regulation via a gas delivery component. During this process, the control device communicates with the gas detection device, the air conditioning system, and the adsorption device to detect the target gas concentration in the passenger compartment and operates in conjunction with the control method described in any of the above embodiments. When the vehicle-mounted air conditioning system operates in economy mode, it acquires the target gas concentration in the passenger compartment. When the target gas concentration in the passenger compartment is greater than or equal to a first threshold, the adsorption device is controlled to adsorb at least one of the target gas in the passenger compartment and the target gas entering the passenger compartment, maintaining the economy mode so that the percentage of in-vehicle gas used by the vehicle-mounted air conditioning system for temperature regulation is greater than or equal to a set value. This can reduce or temporarily prevent the intake of excessive external air into the passenger compartment, allowing for longer-term use of the air in the passenger compartment or the air in the vehicle's air conditioning system for temperature regulation, thereby reducing vehicle energy consumption and improving the vehicle's driving range.

[0079] It should be noted that in Economy mode, the percentage of interior air used by the vehicle's air conditioning system to adjust the temperature is greater than or equal to the set value. This set threshold can be flexibly set according to actual conditions. For example, this set threshold includes one of the following: 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79%, 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, 100%.

[0080] Optionally, in economy mode, the percentage of in-vehicle air used by the vehicle's air conditioning system for temperature adjustment is 70% to 100%.

[0081] Optionally, in economy mode, the percentage of in-vehicle air used by the vehicle's air conditioning system for temperature adjustment is 80% to 100%.

[0082] Optionally, in economy mode, the percentage of in-vehicle air used by the vehicle air conditioning system for temperature adjustment is 90% to 100%.

[0083] In this way, when the vehicle's air conditioning system adjusts the temperature, it can use the air inside the vehicle as much as possible to adjust the temperature, reducing the participation of outside air. This helps to reduce the temperature difference between the air before and after temperature adjustment, thereby reducing the vehicle's energy consumption and improving the vehicle's driving range.

[0084] It should be noted that the economy mode can be set according to actual needs. For example, the economy mode includes automatic mode. When the vehicle's air conditioning system enters automatic mode, the control method described above can utilize the in-vehicle air for temperature regulation as much as possible, reducing the involvement of outside air. This helps to reduce the temperature difference between the air before and after temperature regulation, thereby reducing the vehicle's energy consumption and improving its driving range.

[0085] It should be noted that harmful gases include hydrogen chloride, hydrogen sulfide, sulfur oxides, nitrogen oxides, benzene, toluene, methanol, formaldehyde, ammonia, acetone, and other toxic hydrocarbons.

[0086] It should be noted that there are many ways to implement the air supply component, including but not limited to blowers, fans, centrifugal fans, air compressors, etc., which can deliver gas into the heat exchange component, or the heat exchange component and the adsorption device.

[0087] It should be noted that there are various ways to implement heat exchange components, which usually include heat exchangers, and can at least cool or heat the gas.

[0088] It should be noted that there are various ways to implement a gas detection device, and it can be flexibly configured according to the type of target gas. For example, a gas detection device may include at least one of a carbon dioxide detection sensor, a carbon dioxide concentration detector, a hazardous gas detector, or a humidity sensor.

[0089] It should be noted that there are many ways to implement the control device, such as integrated computer, MOC controller, motion control card, programmable controller, etc.

[0090] It should be noted that the first and second thresholds can be set flexibly according to the actual situation, and no further restrictions are imposed here.

[0091] Combination Figure 3 as well as Figure 4 ,like Figure 6 As shown, in some embodiments, when the vehicle air conditioning system enters the economy mode, the control method further includes: connecting the second air intake to the passenger compartment and disconnecting the third air intake from the outside of the vehicle, so that the percentage of in-vehicle gas used by the vehicle air conditioning system for temperature adjustment is 100%. Thus, when the vehicle air conditioning system enters the economy mode, the second air intake is first connected to the passenger compartment, and the third air intake is disconnected from the outside of the vehicle. This allows for 100% utilization of in-vehicle gas for temperature control, without the use of outside air. This reduces the temperature difference between the gas before and after temperature adjustment, thereby reducing vehicle energy consumption and improving the vehicle's driving range.

[0092] During this process, the third air intake can be dynamically opened or closed according to the target gas content, which can not only meet the temperature regulation requirements, but also ensure the breathing requirements of the air in the vehicle, thus improving the driving experience.

[0093] Furthermore, such as Figure 6 As shown, in some embodiments, after the adsorption device adsorbs the target gas, the control method further includes: when the target gas content in the passenger compartment is still greater than or equal to a first threshold after a first set time, then, while maintaining the economy mode, connecting the third air intake to the outside of the vehicle. Thus, in the economy mode where the percentage of in-vehicle gas used for temperature adjustment by the vehicle's air conditioning system is greater than or equal to a set value, an appropriate amount of external vehicle gas can be drawn in through the third air intake and delivered to the passenger compartment to adjust the target gas content, ensuring that the target gas content in the passenger compartment is less than the first threshold, thereby guaranteeing the vehicle's breathing requirements.

[0094] It should be noted that the initial time setting can be flexibly set according to the actual situation. For example, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, etc.

[0095] like Figure 7 As shown, in some embodiments, after maintaining the economy mode and connecting the third air intake to the outside of the vehicle, the system further includes: when a second predetermined time is reached and the target gas content in the passenger compartment is greater than or equal to a first threshold, the economy mode is exited, and the second air intake is disconnected from the passenger compartment. In this way, external air can be fully utilized to improve the air quality in the passenger compartment, thus ensuring a better driving experience.

[0096] Furthermore, once the air quality in the passenger compartment meets the requirements, the vehicle's air conditioning system switches back to economy mode. This reduces the vehicle's energy consumption and helps increase its driving range.

[0097] It should be noted that the second time setting can be flexibly set according to the actual situation. For example, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, etc.

[0098] Based on any of the above embodiments, such as Figure 7 As shown, in some embodiments, the control method further includes: when the target gas content in the passenger compartment is less than or equal to a second threshold after a third set time, the adsorption device stops adsorbing; wherein the second threshold is less than the first threshold. Thus, by using the adsorption device to reduce the target gas content in the passenger compartment to less than or equal to the second threshold after the third set time, the adsorption device is deactivated and stops adsorbing the target gas, which helps to extend the service life of the adsorption device.

[0099] It should be noted that the third time setting can be flexibly set according to the actual situation. For example, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, etc.

[0100] In some embodiments, the first set time is equal to the third set time.

[0101] It should be noted that the air quality requirements in the passenger compartment can be set according to actual needs. For example, meeting the air quality requirements in the passenger compartment includes ensuring that the target gas content is less than or equal to a second threshold.

[0102] It should be noted that the specific parameters of the first and second thresholds can be flexibly set according to the target gas. For example, the first threshold may include a critical value for carbon dioxide content that causes drowsiness in drivers and passengers, while the second threshold may include a carbon dioxide content that does not cause drowsiness. And / or, the first threshold may include a critical value for the content of harmful gases that endanger the health of drivers and passengers, while the second threshold may include a content of harmful gases that do not endanger the health of drivers and passengers. And / or, the first threshold may include a critical value for the moisture content that causes fogging of vehicle light-transmitting components, while the second threshold may include a moisture content that does not cause fogging of vehicle light-transmitting components.

[0103] Furthermore, it is understandable that the first threshold and the second threshold can be dynamically adjusted based on conditions such as the temperature inside the passenger cabin.

[0104] In some embodiments, the target gas includes carbon dioxide, and the first threshold includes a carbon dioxide content of 1000 ppm. Thus, by monitoring the carbon dioxide content in the passenger compartment using a gas detection device, when the carbon dioxide content in the passenger compartment is greater than or equal to the first threshold, the adsorption device is controlled to adsorb carbon dioxide, thereby reducing the carbon dioxide content in the passenger compartment. This prevents the carbon dioxide content from consistently exceeding 1000 ppm, which could reduce passenger comfort or even cause driver drowsiness and affect driving safety. During this process, when the vehicle's air conditioning system adjusts the temperature, it can utilize the in-vehicle air as much as possible, reducing the involvement of outside air. This helps reduce the temperature difference between the air before and after temperature adjustment, thereby reducing vehicle energy consumption and improving the vehicle's driving range.

[0105] In some embodiments, the target gas includes a harmful gas, and the first threshold includes a harmful gas concentration of 5 mg / m³. 3 Thus, by monitoring the concentration of harmful gases in the passenger compartment using a gas detection device, when the concentration of harmful gases in the passenger compartment is greater than or equal to a first threshold, the adsorption device is controlled to adsorb the harmful gases, thereby reducing the concentration of harmful gases in the passenger compartment and preventing the concentration of harmful gases from exceeding 5 mg / m³ for an extended period. 3This can reduce the health risks for passengers. During this process, when the vehicle's air conditioning system adjusts the temperature, it should utilize the interior air as much as possible, minimizing the involvement of outside air. This helps reduce the temperature difference between the air before and after temperature adjustment, thereby reducing vehicle energy consumption and increasing the vehicle's driving range.

[0106] Optionally, such as Figure 8 As shown, in some embodiments, the adsorption device 300 is reusable. The adsorption device 300 also includes a switching valve 310 and an exhaust section 303. A control device is communicatively connected to the switching valve 310 to control the switching valve 310 to switch between a first position and a second position. When the switching valve 310 is in the first position, the exhaust section 303 is closed, the adsorption outlet section 302 is open, and it communicates with the adsorption inlet section 301. When the switching valve 310 is in the second position, the adsorption outlet section 302 is closed, the exhaust section 303 is open, and it communicates with the adsorption inlet section 301. The adsorption device 300 also includes a second heating component 320 and at least an adsorption component 330 for adsorbing the target gas. The control device is communicatively connected to the second heating component 320 to control the second heating component 320 to heat the adsorption component 330. When the switching valve 310 is in the first position, the second heating component 320 is closed. When the switching valve 310 is in the second position, the second heating component 320 is activated. Thus, the adsorption device 300 can be reused, and the second heating component 320 increases the rate at which the adsorption device 300 releases the target gas. When the adsorption device 300 is normally adsorbing, the switching valve 310 switches to the first position, the exhaust section 303 closes, the adsorption outlet section 302 opens and connects to the adsorption inlet section 301, to adsorb the target gas. When the adsorption device 300 needs to discharge the adsorbed target gas for reuse, the switching valve 310 switches to the second position, the adsorption outlet section 302 closes, the exhaust section 303 opens and connects to the adsorption inlet section 301, and the second heating component 320 is activated to heat the adsorption component 330. This allows the target gas absorbed by the adsorption device 300 to be released and discharged from the adsorption device 300 through the exhaust section 303, enabling the adsorption device 300 to be reused.

[0107] Understandably, the adsorption component 330 achieves reusability through the above method, eliminating the need for frequent replacement of the adsorption device 300, improving user experience, and helping to reduce adsorption costs.

[0108] like Figure 8 As shown, in some embodiments, the air conditioning unit 200 further includes a drainage assembly 280, and the exhaust portion 303 is connected to the drainage assembly 280. Thus, by connecting the exhaust portion 303 to the drainage assembly 280, the target gas released by the adsorption device 300 is easily discharged to the outside of the vehicle 10 through the drainage assembly 280.

[0109] Based on any embodiment of the switching valve 310 described above, such as Figure 8 As shown in some embodiments, it should be noted that the switching valve 310 can be implemented in various ways, as long as it enables selective communication between the adsorption suction section and the exhaust section 303 or the adsorption outlet section 302. For example, the switching valve 310 is a three-way valve. Alternatively, the switching valve 310 may include a first switching valve that controls the opening and closing of the adsorption outlet section 302 and a second switching valve that controls the opening and closing of the exhaust section 303, etc.

[0110] It should be noted that the specific implementation of the adsorption component 330 includes, but is limited to, activated carbon adsorption components.

[0111] Based on any of the above embodiments, in some embodiments, the adsorption device includes a first adsorption element for adsorbing carbon dioxide and harmful gases; when the carbon dioxide content in the passenger compartment is greater than or equal to 1000 ppm and / or the harmful gas content in the passenger compartment is greater than or equal to 5 mg / m³ 3 At this time, at least one of the target gas inside the passenger compartment and the target gas entering the passenger compartment is adsorbed by the first adsorption element to maintain the economic mode. Thus, when the carbon dioxide content in the passenger compartment is greater than or equal to 1000 ppm and / or the content of harmful gases in the passenger compartment is greater than or equal to 5 mg / m³, the economic mode is maintained. 3 In this mode, the first adsorption element adsorbs carbon dioxide and / or harmful gases to improve ride comfort while maintaining economy mode. This, in turn, reduces vehicle energy consumption and helps increase the vehicle's driving range.

[0112] Combined with appendix Figure 8 The adsorption assembly includes a first adsorption element. In some embodiments, when the first adsorption element is in a non-adsorption state or in a set saturated state, the control method further includes: heating the first adsorption element to cause it to release carbon dioxide and / or harmful gases, and then discharging the released carbon dioxide and / or harmful gases to the outside of the vehicle. Thus, by heating the first adsorption element, the carbon dioxide and / or harmful gases absorbed by it can be released and discharged to the outside of the vehicle. This allows the first adsorption element to be reused, eliminating the need for frequent replacement of the adsorption device, improving user experience, and reducing adsorption costs.

[0113] Based on any of the above embodiments, in some embodiments, the target gas includes water vapor, and the first threshold includes a first air humidity value, which is lower than the minimum humidity value required for fogging of the vehicle's light-transmitting components. Thus, by controlling the adsorption device to adsorb water vapor to reduce the air humidity in the passenger compartment, fogging of the vehicle's light-transmitting components can be avoided, thereby improving driving safety.

[0114] During this process, when the vehicle's air conditioning system adjusts the temperature, it can use the air inside the vehicle as much as possible to reduce the participation of outside air. This helps to reduce the temperature difference between the air before and after temperature adjustment, thereby reducing the vehicle's energy consumption and improving its driving range.

[0115] In some embodiments, the adsorption device includes a second adsorption element for adsorbing water vapor. When the water vapor content in the passenger compartment is greater than or equal to a first air humidity value, at least one of the target gas in the passenger compartment and the target gas entering the passenger compartment is adsorbed by the second adsorption element to maintain the economy mode. Thus, when the water vapor content in the passenger compartment is greater than or equal to the first air humidity value, the adsorption of water vapor by the second adsorption element prevents fogging of the vehicle's light-transmitting components while maintaining the economy mode, thereby improving driving safety.

[0116] Combined with appendix Figure 8 The adsorption assembly includes a second adsorption element. In some embodiments, when the adsorption device is in a non-adsorption state or in a set saturation state, the control method further includes heating the second adsorption element to release water vapor, and then discharging the released water vapor to the outside of the vehicle. Thus, by heating the second adsorption element, the water vapor absorbed by the second adsorption element can be released and discharged to the outside of the vehicle. This allows the second adsorption element to be reused, eliminating the need for frequent replacement of the adsorption device, improving user experience, and reducing adsorption costs.

[0117] In other embodiments, when the moisture content in the passenger compartment is less than or equal to a second air humidity value, and the second air humidity value is less than a first air humidity value, the control method further includes heating the second adsorption element to release moisture, and then delivering the released moisture into the passenger compartment. Thus, by heating the second adsorption element, the moisture absorbed by it can be released and used to humidify the air in the passenger compartment, thereby increasing the air humidity and improving passenger comfort. This also allows the second adsorption element to be reused, eliminating the need for frequent replacement of the adsorption device, improving user experience, and reducing adsorption costs.

[0118] In some embodiments, when obtaining the target gas content in the passenger compartment, the control method further includes: obtaining the temperature information of the vehicle's light-transmitting components, and selecting a first air humidity value based on the temperature information of the vehicle's light-transmitting components. Thus, by selecting a suitable first air humidity value based on the temperature information of the vehicle's light-transmitting components, the adsorption device can be effectively controlled to adsorb water vapor before the vehicle's light-transmitting components fog up, thereby reducing the air humidity in the passenger compartment and preventing fogging of the vehicle's light-transmitting components, thus improving driving safety.

[0119] It should be noted that vehicle light-transmitting components include window glass. For example, the windshield, driver's side window, passenger side window, rear side windows, trunk glass, etc.

[0120] Furthermore, in some embodiments, when obtaining the temperature information of the vehicle's light-transmitting components, the method further includes: obtaining the temperature information of the vehicle's light-transmitting components for the windshield, driver's side window, passenger side window, and trunk glass, as well as the humidity information of a designated area for the vehicle's light-transmitting components, to obtain fogging information for the windshield, driver's side window, passenger side window, and trunk glass. Based on the fogging information of the windshield, driver's side window, passenger side window, and trunk glass, and combined with driving safety anti-fogging weights, the vehicle's light-transmitting component most in need of anti-fogging is determined. Based on the temperature information of the vehicle's light-transmitting component most in need of anti-fogging, a first air humidity value is selected. The vehicle's light-transmitting component temperature information includes the glass dew point temperature and the glass surface temperature; the humidity information of the designated area for the vehicle's light-transmitting component includes the water vapor content and the rate of humidity increase in the designated area. Thus, based on the temperature information of the vehicle's light-transmitting components—the windshield, driver's side window, passenger side window, and trunk glass—and the humidity information of the designated areas of these components during vehicle operation, fogging information for each window is obtained. Combining this fogging information with driving safety anti-fogging weights, the vehicle's light-transmitting components most in need of fogging prevention are identified. Furthermore, based on the temperature information of the light-transmitting component most in need of fogging prevention, a first air humidity value is selected. This allows for effective control of the adsorption device to absorb moisture before fogging occurs in that component, reducing the air humidity in the passenger compartment and preventing fogging of the vehicle's light-transmitting components, thereby improving driving safety.

[0121] Optionally, the system can further differentiate between the upper, middle, and lower parts of the windshield; and the distance of the windshield from the driver's side, the passenger side, and the side windows from the rearview mirror (far, medium, and near) to further classify the fogging risk level. This facilitates prioritizing different areas according to their impact on driving safety, and by combining sensor data with driving safety fogging weights, it can output the vehicle's light-transmitting components that currently require the most fogging prevention based on current needs.

[0122] For example, the lower part of the windshield, the area of ​​the driver's side window near the rearview mirror, and the area of ​​the passenger side window near the rearview mirror are of the highest priority, while the rearview mirror and the trunk glass are of the second highest priority.

[0123] Based on any of the above embodiments, in some embodiments, after the adsorption device adsorbs the target gas, the control method further includes: when the target gas content in the passenger compartment is still greater than or equal to a first threshold after a first set time, heating the gas supplied to the vehicle's light-transmitting component and / or increasing the proportion of external gas entering the passenger compartment. In this way, by heating the gas supplied to the vehicle's light-transmitting component and blowing it towards it, the temperature of the component can be increased, thereby increasing the humidity for fogging and preventing fogging, thus improving driving safety. And / or, by increasing the proportion of external gas entering the passenger compartment, the air humidity inside the passenger compartment can be reduced, further preventing fogging of the vehicle's light-transmitting component and improving driving safety.

[0124] Based on any of the above embodiments, in some embodiments, the adsorption intake section is connected to at least one of the heat exchange component 210, the air supply component 220, and the passenger compartment 101. Thus, the adsorption device 300 can draw in the target gas from at least one of the heat exchange component 210, the air supply component 220, and the passenger compartment 101 through the adsorption intake section, thereby reducing the content of the target gas entering the internal circulation of the vehicle 10. This allows for increased air conditioning recirculation ratio and reduced energy consumption while maintaining passenger comfort.

[0125] Optionally, such as Figure 3 as well as Figure 4 As shown, in some embodiments, the adsorption intake section is connected to the second air intake section 222 and / or the third air intake section 223, and the adsorption outlet section 302 is connected to the second air outlet section 221 and / or the heat exchange component 210. Thus, the adsorption device 300 can draw in the target gas from the second air intake section 222 and / or the third air intake section 223 through the adsorption intake section, achieving adsorption of the target gas. The adsorbed gas is then transported through the adsorption outlet section 302 to the second air outlet section 221 and / or the heat exchange component 210, thereby reducing the content of the target gas entering the internal circulation of the vehicle 10. This allows for increased air conditioning internal circulation ratio and reduced energy consumption while maintaining passenger comfort.

[0126] like Figure 2 As shown, in some embodiments, the air conditioning device 200 further includes a first duct 230, a first air intake 211 connected to a second air outlet through the first duct 230, an adsorption intake duct connected to the first duct 230, and an adsorption outlet duct 302 connected to a heat exchange component 210. Thus, the adsorption device 300 can draw in the target gas from the first duct 230 through the adsorption intake duct, achieving adsorption of the target gas, and then transport the adsorbed gas to the heat exchange component 210 through the adsorption outlet duct 302. This reduces the content of the target gas entering the internal circulation of the vehicle 10, thereby increasing the proportion of air conditioning internal circulation and reducing energy consumption while ensuring passenger comfort.

[0127] like Figures 9 to 11 As shown, in some embodiments, the air conditioning device 200 further includes a first duct 230, through which the first air intake 211 is connected to the second air outlet. The air delivery component 220 further includes a fourth air intake 224, with the adsorption suction section connected to the first duct 230 and the adsorption outlet 302 connected to the fourth air intake 224. Thus, the adsorption device 300 can draw in the target gas from the first duct 230 through the adsorption suction section, achieving adsorption of the target gas, and then deliver the adsorbed gas to the air delivery component 220 through the adsorption outlet 302. This reduces the content of the target gas entering the internal circulation of the vehicle 10, thereby increasing the proportion of air conditioning internal circulation and reducing energy consumption while ensuring passenger comfort.

[0128] like Figure 12 As shown, in some embodiments, the air conditioning device 200 further includes a second duct 240, a second air outlet 221 connected to the air outlet 102 of the passenger compartment 101 via the second duct 240, an adsorption intake section connected to the second duct 240 and / or the second air outlet 221, and an adsorption exhaust section 302 connected to the second duct 240 and / or the air outlet 102 of the passenger compartment 101. Thus, the adsorption device 300 can draw in the target gas from the second duct 240 and / or the second air outlet 221 through the adsorption intake section, achieving adsorption of the target gas, and then transport the adsorbed gas to the second duct 240 and / or the air outlet 102 of the passenger compartment 101 via the adsorption exhaust section 302. This reduces the content of the target gas entering the internal circulation of the vehicle 10, thereby increasing the proportion of air conditioning internal circulation and reducing energy consumption while ensuring passenger comfort.

[0129] like Figure 13 As shown, in some embodiments, the air conditioning device 200 further includes a third duct 250, a third air intake 223 connected to the air intake 103 of the passenger compartment 101 via the third duct 250, an adsorption suction section connected to the third duct 250 and / or the air intake 103 of the passenger compartment 101, and an adsorption exhaust section 302 connected to the third duct 250 and / or the third air intake 223. Thus, the adsorption device 300 can draw in the target gas from the third duct 250 and / or the air intake 103 of the passenger compartment 101 through the adsorption suction section, achieving adsorption of the target gas, and then transport the adsorbed gas to the third duct 250 and / or the third air intake 223 through the adsorption exhaust section 302. This reduces the content of the target gas entering the internal circulation of the vehicle 10, thereby increasing the proportion of air conditioning internal circulation and reducing energy consumption while ensuring passenger comfort.

[0130] like Figure 14As shown, in some embodiments, the air conditioning device 200 further includes a first heating component 260 and a window blowing pipe 270 connected to the air supply component 220. The adsorption intake section is connected to the air supply component 220, and the adsorption outlet section 302 is connected to the window blowing pipe 270. The first heating component 260 is disposed between the adsorption outlet section 302 and the window blowing pipe 270 to heat the gas adsorbed by the adsorption device 300. In this way, the adsorption device 300 can draw in the target gas from the air supply component 220 through the adsorption intake section, thereby adsorbing the target gas, and then transporting the adsorbed gas to the window blowing pipe 270 through the adsorption outlet section 302. This reduces the content of the target gas entering the internal circulation of the vehicle 10, thereby increasing the internal circulation ratio of the air conditioning while ensuring passenger comfort and reducing energy consumption. Furthermore, heating the adsorption device 300 by the first heating component 260 increases the temperature of the gas delivered to the window blowing pipe 270, thereby reducing or preventing fogging of the vehicle's light-transmitting components and improving driving safety.

[0131] It should be noted that the adsorption device 300 is reusable. Alternatively, the adsorption device 300 is not reusable and needs to be replaced periodically.

[0132] Based on any embodiment of the second heating component 320 described above, such as Figure 15 As shown, in some embodiments, the heat exchange component 210 further includes a heat exchange chamber 213 and a heat exchanger 214 disposed in the heat exchange chamber 213. The heat exchange chamber 213 is connected to the drainage component 280. The first air inlet 211 and the first air outlet 212 are connected to the heat exchange chamber 213. The heat exchanger 214 is used to regulate the temperature of the gas entering the heat exchange chamber 213. The exhaust section 303 is connected to the drainage component 280 through the heat exchange chamber 213. When the heat exchanger 214 heats the gas in the air conditioning unit 200 and the switching valve 310 is in the second position, the exhaust section 303 opens and connects to the heat exchange chamber 213. Thus, when the adsorption device 300 needs to discharge the adsorbed target gas for reuse, the switching valve 310 switches to the second position, the adsorption exhaust section 302 closes, the exhaust section 303 opens and connects to the adsorption inlet section 301, and the second heating component 320 is activated to heat the adsorption component 330. This causes the gas flowing out of the adsorption device 300 to carry heat, which is then discharged into the heat exchange chamber 213 through the exhaust section 303. The heat generated by the adsorption device 300 is used to heat the heat exchanger 214, which can improve the waste heat utilization rate, further save energy consumption, and increase the driving range of the vehicle 10.

[0133] Optionally, the exhaust section 303 is an exhaust pipe, part of which connects to the exhaust assembly after passing through the heat exchange chamber 213. Thus, by providing an exhaust pipe, the target gas released by the adsorption device 300 will not flow out from the second exhaust section 221. Furthermore, the exhaust pipe, passing through the heat exchange chamber 213, can transfer heat to the heat exchanger 214, thereby fully utilizing the waste heat of the adsorption device 300 to improve the heat exchange effect.

[0134] like Figure 16 As shown, in some embodiments, the heat exchange component 210 further includes a third air outlet 215 that blows gas toward the vehicle's light-transmitting component, and the adsorption outlet 302 is connected to the third air outlet 215. In this way, the gas flowing out of the adsorption device 300 can flow into the third air outlet 215 through the adsorption outlet 302 and be blown toward the vehicle's light-transmitting component.

[0135] Furthermore, in some embodiments, the air conditioning device 200 also includes a window blowing duct 270 and a third heating component 290. The third air outlet 215 is connected to the adsorption outlet 302 through the window blowing duct 270, and the third heating component 290 is used to heat the gas inside the window blowing duct 270. Thus, the adsorption device 300 can draw in the target gas through the adsorption intake section, achieving adsorption of the target gas, and then transport the adsorbed gas to the window blowing duct 270 through the adsorption outlet 302. This reduces the content of the target gas entering the internal circulation of the vehicle 10, thereby increasing the internal circulation ratio of the air conditioning while ensuring passenger comfort and reducing energy consumption. Heating the adsorption device 300 with the third heating component 290 and directing the heated gas from the adsorption device 300 to the window blowing duct 270 through the adsorption outlet 302 increases the temperature of the gas delivered to the window blowing duct 270, thereby reducing or preventing fogging of the vehicle's light-transmitting components and improving driving safety.

[0136] like Figure 17 As shown, in some embodiments, the adsorption device 300 can passively absorb the target gas in the air conditioning unit 200 and / or the passenger compartment 101. That is, after the adsorption device 300 is turned on, the gas delivered by the air supply component will be partially delivered to the adsorption device 300 for adsorption. Alternatively, after the adsorption device 300 is turned on, when the air supply component draws in the gas, it can generate a negative pressure in the adsorption outlet section 302 of the adsorption device 300, causing the gas in the air conditioning unit and the gas in the passenger compartment 101 to enter the adsorption device 300. Alternatively, after the adsorption device 300 is turned on, the gas flowing out of the heat exchange component 210 will be partially delivered to the adsorption device 300 for adsorption.

[0137] In some embodiments, the adsorption device 300 can actively absorb target gases within the air conditioning unit 200 and / or the passenger compartment 101.

[0138] like Figure 17As shown, in some embodiments, the adsorption device 300 includes a housing assembly 340 and an adsorption assembly 330 for adsorbing the target gas. The housing assembly 340 is provided with an adsorption chamber 341. An adsorption inlet 301 and an adsorption outlet 302 are disposed in the housing assembly 340 and communicate with the adsorption chamber 341 respectively. The adsorption assembly 330 is disposed within the adsorption chamber 341 and is positioned in the flow direction from the adsorption inlet 301 to the adsorption outlet 302. Thus, by forming the adsorption chamber 341 through the housing assembly 340, it is convenient to place the adsorption assembly 330 within the adsorption chamber 341 and position it in the flow direction from the adsorption inlet 301 to the adsorption outlet 302, so that when the gas flows through the adsorption assembly 330, the target gas it carries is adsorbed, thereby reducing the target gas content of the gas.

[0139] Furthermore, such as Figure 17 As shown, in some embodiments, the adsorption device 300 further includes an airflow driving component communicatively connected to the control device. The airflow driving component is disposed within the adsorption chamber 341 and is used to generate airflow from the adsorption inlet 301 to the adsorption outlet 302. The control method further includes that when the gas detection device 100 detects that the target gas content in the passenger compartment 101 is greater than or equal to a first threshold, the control device controls the airflow driving component to start, so as to actively adsorb the target gas content in the air conditioning unit 200 and / or the passenger compartment 101. This can reduce or temporarily prevent the third air intake 223 from drawing in excessive external gas from the vehicle 10 into the air conditioning unit 200 for circulation, thereby improving the internal gas circulation ratio within the passenger compartment 101.

[0140] Based on any embodiment of the adsorption component 330 described above, in some embodiments, the adsorption component 330 is also used to adsorb water vapor and / or harmful gases. Thus, the adsorption component 330 can also purify harmful gases within the passenger compartment 101 to further improve user comfort. And / or the adsorption component 330 can also adsorb water vapor within the passenger compartment 101, thereby reducing the air humidity within the passenger compartment 101 and reducing or preventing fogging of vehicle light-transmitting components.

[0141] like Figure 17 As shown, in some embodiments, the adsorption assembly 330 further includes a first adsorption element 331 for adsorbing carbon dioxide and / or harmful gases and a second adsorption element 332 for adsorbing water vapor, wherein the first adsorption element 331 and the second adsorption element 332 are disposed spaced apart within the adsorption chamber 341. Thus, the first adsorption element 331 is used to adsorb carbon dioxide and / or harmful gases, while the second adsorption element 332 is used to adsorb water vapor.

[0142] It should be noted that the first adsorbent 331 can be implemented in various ways, as long as it can adsorb carbon dioxide. For example, the adsorption device 300 may contain an activated carbon adsorption layer. Alternatively, the adsorption device 300 may also include an alkaline solution (including sodium hydroxide solution, calcium hydroxide solution, sodium bicarbonate, etc.), through which the gas entering the adsorption device 300 passes before exiting. Another example is the adsorption device 300, which may also include quicklime.

[0143] Based on any of the above embodiments, such as Figure 17 As shown, in some embodiments, the adsorption chamber 341 includes a first chamber 304 accommodating a first adsorption element 331 and a second chamber 305 accommodating a second adsorption element 332. The first chamber 304 and the second chamber 305 are respectively connected to the adsorption outlet section 302. The adsorption device 300 also includes a first control valve 360 ​​and a second control valve 370 communicatively connected to the control device. The first chamber 304 is connected to the adsorption inlet section 301 through the first control valve 360, and the second chamber 305 is connected to the adsorption inlet section 301 through the second control valve 370. The control device can control the opening or closing of the first control valve 360 ​​according to the carbon dioxide content in the passenger compartment 101. The gas detection device 100 is also used to detect the enthalpy and humidity in the passenger compartment 101. The control device is communicatively connected to the gas detection device 100 to control the opening or closing of the second control valve 370 according to the enthalpy and humidity in the passenger compartment 101. Thus, the first chamber 304 and the second chamber 305 respectively house the first adsorbent 331 and the second adsorbent 332, and the first control valve 360 ​​controls the connection or closure of the first chamber 304 and the adsorption air inlet 301. This allows the control device to control the opening or closing of the first control valve 360 ​​based on the carbon dioxide content in the passenger compartment 101. The second control valve 370 controls the connection between the second chamber 305 and the adsorption air inlet 301. This facilitates communication between the control device and the gas detection device 100, allowing the control device to control the opening or closing of the second control valve 370 based on the enthalpy and humidity levels in the passenger compartment 101. In other words, dehumidification and the removal of carbon dioxide and harmful gases can be performed separately, avoiding the need to use the second adsorbent 332 to adsorb moisture when removing carbon dioxide and harmful gases in a dry environment, which would lead to excessively dry air in the passenger compartment 101 and negatively impact passenger comfort.

[0144] like Figure 17 As shown, in conjunction with the aforementioned switching valve 310 and exhaust section 303, when the first adsorption element 331 is reusable, it can be connected to the first chamber 304 via the switching valve 310, or connected to the adsorption exhaust section 302. This facilitates the reuse of the adsorption device 300.

[0145] Based on any of the above embodiments, such as Figure 17As shown, in some embodiments, the adsorption device 300 further includes a fourth heating component 380 communicatively connected to a control device. The fourth heating component 380 is disposed in the second cavity 305 and is used to heat the second adsorption element 332. The control method further includes:

[0146] When the enthalpy-humidity level inside the passenger compartment 101 is greater than or equal to the first air humidity value, the second control valve 370 opens and the fourth heating component 380 closes. When the enthalpy-humidity level inside the passenger compartment 101 is less than or equal to the second air humidity value, the second control valve 370 opens and the fourth heating component 380 activates, with the second air humidity value being less than the first air humidity value. Thus, when the humidity level inside the passenger compartment 101 is greater than or equal to the first air humidity value, the second control valve 370 opens and the fourth heating component 380 closes, allowing the second adsorption element 332 to adsorb moisture inside the passenger compartment 101. Conversely, when the enthalpy-humidity level inside the passenger compartment 101 is less than or equal to the second air humidity value, the second control valve 370 opens and the fourth heating component 380 activates, causing the second adsorption element 332 to release moisture upon heating. This moisture is then used to increase the humidity level inside the passenger compartment 101, preventing the air inside the passenger compartment 101 from becoming too dry.

[0147] It should be noted that the first and second air humidity values ​​can be flexibly set according to the actual situation, and no further restrictions are imposed here.

[0148] It should be noted that the first heating component 260, the second heating component 320, the third heating component 290 and the fourth heating component 380 can be implemented in various ways, including but not limited to heating wire, heating tube, heating strip, etc.

[0149] Based on any of the above embodiments, such as Figure 18 and / or Figure 19 As shown, in some embodiments, the vehicle body assembly 11 includes an instrument panel assembly 11a, an armrest box assembly 11b, and a frame assembly 11c, with the adsorption device 300 disposed on at least one of the instrument panel assembly 11a, armrest box assembly 11b, and frame assembly 11c. Thus, the adsorption device 300 can be flexibly disposed on the vehicle body assembly 11, reducing the assembly difficulty of the vehicle 10.

[0150] It should be noted that the frame components include A-pillars, B-pillars, or C-pillars, etc.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature.
