Description

Technical Field

[0001] The present invention relates to the technical field of vehicle-mounted equipment, and in particular to an in-vehicle air conditioning system and a conditioning method thereof. Background Art

[0002] In-car air quality directly impacts driver safety and health: insufficient oxygen concentration in a car can cause dizziness, drowsiness, and other hypoxic symptoms, leading to slow reaction times while driving. Excessive levels of pollutants such as PM2.5 and formaldehyde can irritate the respiratory tract, and prolonged exposure to such an environment can cause health problems. Therefore, in-car air conditioning systems are crucial for enhancing the driving experience. However, existing in-car air conditioning systems have the following limitations:

[0003] (1) Functional separation: Traditional vehicle-mounted oxygen generators only produce oxygen through molecular sieve adsorption technology and have a single function; air purification equipment mostly uses filter filtration and lacks active oxygen enrichment function; fragrance systems are mostly independent atomization devices and have no coordination with the oxygen production and purification systems.

[0004] (2) Large space occupation and high energy consumption: The independent operation of multiple devices results in large space occupation, high energy consumption and complex control in the vehicle, making it difficult to meet the user's comprehensive needs for health, comfort and convenience.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0052] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0053] like Figure 1 As shown, an in-vehicle air conditioning system includes a monitoring module 100, a human-computer interaction module 200, a purification module 400, an oxygen production module 500, a fragrance module 600, an air valve module 700 and a control module 300;

[0054] The monitoring module 100 is used to obtain in-vehicle air quality monitoring data;

[0055] The human-computer interaction module 200 is used to display the in-vehicle air quality monitoring data in real time and receive human control instructions;

[0056] The purification module 400 is used to purify the air inside the vehicle;

[0057] The oxygen production module 500 is used to produce oxygen;

[0058] The fragrance module 600 is used to atomize and decompose the fragrance solution;

[0059] The air valve module 700 includes an input pipe 701, a first switching component, a second switching component, and an output pipe 702. The input pipe 701 connects the external air with the input end of the purification module 400, and the output pipe 702 connects the external air with the output end of the fragrance module 600. The output end of the purification module 400 is selectively connected to the input end of the oxygen production module 500 or the input end of the fragrance module 600 via the first switching component. The output end of the oxygen production module 500 is selectively connected to the input end of the fragrance module 600 or the output pipe 702 via the second switching component.

[0060] The monitoring module 100, the human-computer interaction module 200, and the control module 300 are electrically connected to each other, and the purification module 400, the oxygen production module 500, the fragrance module 600, the first switching component, and the second switching component are all electrically connected to the control module 300;

[0061] Among them, under the control of the control module 300, the purification module 400 is always in operation, at least one of the oxygen production module 500 and the fragrance module 600 is in operation, and the air circulation direction is regulated by the first switching component and the second switching component to achieve a combined function of the purification function with one or more of the oxygen production function and the fragrance function.

[0062] First, it is known from the background art that traditional vehicle-mounted oxygen concentrators, air purification equipment, and fragrance systems have single functions and are independent of each other, and cannot meet the user's comprehensive needs for multiple air conditioning functions.

[0063] Therefore, the in-vehicle air conditioning system, through the coordinated operation of control module 300 and valve module 700, enables the coordinated activation of one or more of the purification module 400, oxygen generation module 500, and fragrance module 600. For example, when the purification module 400 and oxygen generation module 500 are in operation, they first purify the external air before generating oxygen-enriched air through the oxygen generation module 500, thereby simultaneously addressing the problems of excessive air pollutants and insufficient oxygen. The purification module 400 and fragrance module 600, when in operation, simultaneously eliminate odors and emit fragrance, improving the air quality inside the vehicle. When the purification module 400, oxygen generation module 500, and fragrance module 600 are all activated, the vehicle can enjoy fragrant, oxygen-enriched air.

[0064] Secondly, it is known from background technology that the independent operation of multiple devices will result in large space occupation in the vehicle, high energy consumption and complex control.

[0065] Therefore, when multiple modules in this in-vehicle air conditioning system are activated in conjunction, they share input and output pipes 702, airflow channels, and power resources. For example, the fragrance module 600 utilizes residual airflow pressure in the air ducts from the purification module 400 or oxygen generator module 500 to diffuse fragrance, eliminating the need for a separate power unit. The valve module 700 controls the first and second switching components to rationally regulate air flow direction, reducing the complexity of the piping layout. Furthermore, users can centrally control multiple modules through the human-computer interaction module 200, streamlining the operation process.

[0066] Finally, it is known from background technology that in plateaus or closed environments, existing equipment cannot simultaneously increase oxygen concentration and purify the air; in foggy weather, the purification efficiency and oxygen production function cannot be optimized in conjunction.

[0067] When the air conditioning system in the vehicle is in a plateau environment, the purification module 400 and the oxygen production module 500 are linked together to first purify the thin external air that may contain impurities, and then increase the oxygen concentration through the oxygen production module 500 to ensure the oxygen supply and air cleanliness in the vehicle; in foggy weather, the purification, oxygen production and fragrance module 600 are fully linked together, the purification module 400 efficiently filters PM2.5 and other pollutants, the oxygen production module 500 maintains the oxygen content, and the fragrance module 600 improves the odor, thereby optimizing the air quality in the vehicle in all aspects.

[0068] In summary, the in-car air conditioning system has the following technical effects:

[0069] 1. Solve the problem of functional fragmentation and achieve deep functional integration: Break the functional isolation of traditional equipment, achieve deep integration and collaborative work of multiple functions, meet users' diverse needs for a healthy and comfortable driving environment, and significantly improve the driving experience.

[0070] 2. Reduced space and energy consumption, improving convenience: Compared with traditional independent operation of multiple devices, this system significantly reduces space occupied within the vehicle and reduces overall system energy consumption; the unified control method also greatly improves user convenience.

[0071] 3. Enhanced environmental adaptability to cope with complex scenarios: The system can flexibly combine module operating modes according to different environmental conditions, quickly responding to and resolving in-vehicle air quality issues in various complex scenarios, effectively reducing the risk of passengers suffering from hypoxia and inhalation of harmful pollutants, and significantly enhancing the system's environmental adaptability and safety.

[0072] To further illustrate, the monitoring module 100 includes an air quality sensor 101 and an oxygen concentration sensor 102;

[0073] The air quality sensor 101 is used to detect the air quality parameters in the vehicle, wherein the air quality parameters in the vehicle include the concentration of particulate matter, PM2.5 and PM10 in the vehicle;

[0074] The oxygen concentration sensor 102 is used to detect the oxygen concentration in the vehicle.

[0075] The monitoring module 100 continues to play a key role in different environments. In high-altitude environments, if the oxygen concentration sensor 102 detects a low oxygen level and the air quality sensor 101 detects a high level of impurities in the air, the control module 300 immediately activates the purification module 400 and oxygen generation module 500, first purifying the thin, potentially impure outside air before increasing the oxygen concentration through the oxygen generation module 500. In foggy weather, if the air quality sensor 101 detects excessive concentrations of pollutants such as PM2.5 and PM10, the control module 300 activates the purification, oxygen generation, and fragrance modules 600. The purification module 400 efficiently filters pollutants, the oxygen generation module 500 maintains oxygen levels, and the fragrance module 600 improves odor, comprehensively optimizing the air quality inside the vehicle.

[0076] With the help of real-time environmental data provided by the monitoring module 100, the in-vehicle air conditioning system flexibly combines module operating modes according to different environmental conditions, quickly responds to and solves in-vehicle air quality problems in various complex scenarios, effectively reduces the risk of passengers suffering from hypoxia and inhaling harmful pollutants, and significantly enhances the environmental adaptability and safety of the system.

[0077] It should be noted that the monitoring module 100 is not limited to the above two sensors. In order to further improve the function of the monitoring module 100, other sensors that play a sensing role in the coordinated operation of the air conditioning system in the vehicle are included.

[0078] To further illustrate, the purification module 400 includes a HEPA filter 401, activated carbon 402, an ultraviolet lamp 403, and a brushless motor 404;

[0079] The brushless motor 404 is used to draw air into the purification module 400 through the input pipe 701;

[0080] The HEPA filter 401 is used to intercept particulate pollutants in the sucked air, wherein the particulate pollutants include dust and PM2.5;

[0081] The activated carbon 402 is used to absorb odors in the sucked air;

[0082] The ultraviolet lamp 403 is used to sterilize bacteria in the sucked air.

[0083] When the control module 300 controls the purification module 400 to start, the brushless motor 404 starts, and the air is sucked into the purification module 400, and passes through the HEPA filter 401 to intercept dust and particulate pollutants such as PM2.5, the activated carbon 402 to absorb odors, and the ultraviolet lamp 403 for sterilization. After purification is completed, through the first switching component, the purified air can selectively enter the oxygen production module 500 to further increase the oxygen concentration, or enter the fragrance module 600 to realize fragrance diffusion.

[0084] It should be noted that the purification module 400 is not limited to the above structural settings. In order to further improve the function of the purification module 400, other purification structures that work together with the air conditioning system in the vehicle to purify the air are included to ensure that the system always maintains efficient air conditioning capabilities in different scenarios.

[0085] To further illustrate, the oxygen production module 500 includes an oil-free compressor 501, a molecular sieve 502 and an oxygen storage tank 503;

[0086] The oil-free compressor 501 is used to drive external air into the molecular sieve 502 , and the molecular sieve 502 is used to separate oxygen and nitrogen from the external air to obtain high-concentration oxygen, and inject the oxygen into the oxygen storage tank 503 for storage.

[0087] When the control module 300 controls the oxygen production module 500 to start, the oil-free compressor 501 drives the purified air into the molecular sieve 502. The molecular sieve 502 separates oxygen and nitrogen, injects high-concentration oxygen into the oxygen storage tank 503 for storage, and then delivers the oxygen-enriched air into the vehicle through the second switching component.

[0088] It should be noted that the oxygen production module 500 is not limited to the above structural settings. Other oxygen production structures that work in conjunction with the air conditioning system in the vehicle to produce oxygen are included to ensure that the system maintains efficient air conditioning capabilities in different scenarios.

[0089] To further illustrate, the fragrance module 600 includes an ultrasonic device 601 and a liquid storage bottle 602;

[0090] The liquid storage bottle 602 is used to store the fragrance solution, and the ultrasonic device 601 is used to atomize and decompose the fragrance solution through high-frequency mechanical vibration.

[0091] When the control module 300 controls the fragrance module 600 to start, the fragrance solution in the liquid storage bottle 602 is atomized and decomposed in the ultrasonic device 601 through the high-frequency mechanical vibration of the piezoelectric ceramic atomizer, and then the residual pressure of the airflow of the purification module 400 or the oxygen production module 500 is used to diffuse the fragrance into the vehicle.

[0092] It should be noted that the fragrance module 600 is not limited to the above structural settings. Other fragrance structures that work together with the air conditioning system in the vehicle to provide fragrance are included to ensure that the system maintains efficient air conditioning capabilities in different scenarios.

[0093] To further illustrate, the first switching assembly includes a first pipe 703, a second pipe 704 and a first two-position three-way solenoid valve 705;

[0094] The air inlet of the first two-position three-way solenoid valve 705 is connected to the output of the purification module 400, one air outlet of the first two-position three-way solenoid valve 705 is connected to the air inlet of the fragrance module 600 through the first pipe 703, and the other air outlet of the first two-position three-way solenoid valve 705 is connected to the air inlet of the oxygen production module 500 through the second pipe 704;

[0095] The second switching assembly includes a third pipe 706, a fourth pipe 707 and a second two-position three-way solenoid valve 708;

[0096] The air inlet end of the second two-position three-way solenoid valve 708 is connected to the output end of the oxygen production module 500, one air outlet end of the second two-position three-way solenoid valve 708 is connected to the air inlet end of the fragrance module 600 through the third pipe 706, and the other air outlet end of the second two-position three-way solenoid valve 708 is connected to the output pipe 702 through the fourth pipe 707.

[0097] Specifically, the air valve module 700 ensures that the purified and oxygenated air can effectively drive the diffusion of fragrance through the coordinated work of the first two-position three-way solenoid valve 705 and the second two-position three-way solenoid valve 708, ensuring that the system continues to operate efficiently and with stable energy consumption.

[0098] A method for regulating an in-vehicle air conditioning system as described above comprises the following steps:

[0099] S1, real-time acquisition of current in-vehicle air quality monitoring data and receiving human control instructions;

[0100] S2. Determine the operating mode of the purification module 400, the oxygen production module 500, and the fragrance module 600 based on the current in-vehicle air quality monitoring data and the manual control instructions;

[0101] S3. According to the result of the working mode determination, the air flow direction is regulated by the air valve module 700;

[0102] The operation modes of the purification module 400 , the oxygen production module 500 and the fragrance module 600 include that the purification module 400 is always operating, and at least one of the oxygen production module 500 and the fragrance module 600 is operating.

[0103] To further illustrate, the working modes of the purification module 400, the oxygen production module 500 and the fragrance module 600 specifically include:

[0104] First linkage mode: the oxygen production module 500 and the purification module 400 are started in linkage;

[0105] Second linkage mode: the fragrance module 600 and the purification module 400 are linked and turned on;

[0106] Full linkage mode: the purification module 400, the oxygen production module 500 and the fragrance module 600 are turned on synchronously.

[0107] Specifically, step S1 utilizes the air quality sensor 101 and oxygen concentration sensor 102 in the monitoring module 100, as well as any integrated temperature and humidity sensors and hazardous gas sensors, to collect real-time in-vehicle air quality parameters, including particulate matter concentrations (PM2.5 and PM10), oxygen concentrations, temperature and humidity, and hazardous gases such as carbon monoxide and formaldehyde. Simultaneously, the human-computer interaction module 200 is on standby to receive user control commands, such as manual activation / deactivation of specific modules, via the touchscreen or voice input.

[0108] Specifically, step S2 uses the control module 300 to analyze and process the acquired data and instructions:

[0109] When only monitoring data is triggered:

[0110] If the oxygen concentration sensor 102 detects that the oxygen concentration is lower than a set threshold value, such as 23%, and the air quality sensor 101 feedbacks that the particulate matter concentration exceeds the standard, the control module 300 determines to start the linkage mode of the purification module 400 and the oxygen production module 500;

[0111] When the air quality sensor 101 detects that the air quality pollution data is greater than the warning value, but the oxygen concentration is normal, the control module 300 determines to start the linkage mode of the purification module 400 and the fragrance module 600;

[0112] If it is detected that the oxygen concentration is lower than the set threshold and the air quality pollution data is greater than the warning level, the control module 300 determines that the purification module 400, the oxygen production module 500 and the fragrance module 600 are in full-on mode.

[0113] Manual control command trigger:

[0114] If the user chooses to directly activate either the oxygen production module 500 or the fragrance module 600 through the human-computer interaction module 200, the control module 300 ignores the current monitoring data and automatically activates the purification module 400. If the user chooses to directly activate the purification module 400, the control module 300 ignores the current monitoring data and automatically activates the oxygen production module 500 and the fragrance module 600.

[0115] Specifically, in step S3, the air valve module 700 regulates the air flow path through the first two-position three-way solenoid valve 705 and the second two-position three-way solenoid valve 708 according to the instruction of the control module 300:

[0116] The purification module 400 is linked to the oxygen production module 500: the first two-position three-way solenoid valve 705 is switched to a state of connection with the second pipe 704, allowing the air output from the purification module 400 to enter the oxygen production module 500 through the second pipe 704; after the oxygen production module 500 completes oxygen production, the second two-position three-way solenoid valve 708 is switched to a state of connection with the fourth pipe 707, delivering oxygen-enriched air into the vehicle.

[0117] Purification module 400 and fragrance module 600 are linked: first, second, three-way solenoid valve 705 is switched to connect with first pipe 703, and purified air enters fragrance module 600 through first pipe 703; ultrasonic device 601 in fragrance module 600 atomizes the fragrance solution, which is then diffused into the vehicle through output pipe 702 using the residual air pressure from purification module 400.

[0118] The three modules are fully linked: the first two-position three-way solenoid valve 705 is switched to a connected state with the second pipe 704. The air purified by the purification module 400 first enters the oxygen production module 500 through the second pipe 704. After oxygen production, it is switched to a connected state with the third pipe 706 through the second two-position three-way solenoid valve 708, driving the fragrance to diffuse, and finally delivered into the vehicle through the output pipe 702.

[0119] In summary, this adjustment method is used to adjust an in-vehicle air conditioning system as described above, in which the purification module 400, oxygen production module 500 and fragrance module 600 work together under the control of the control module 300 and the air valve module 700 to realize the linkage logic of "oxygen production must be purified, and fragrance depends on the residual pressure of the air flow to diffuse", thereby simultaneously improving the oxygen concentration, purifying the air and adjusting the odor.

[0120] It should be noted that the control and coordination between the above modules are all realized by PLC, and the modification of the existing technology in this specific implementation method lies in the hardware part. At the same time, the computer program involved is a simple program that can be easily implemented by technical personnel in this field using existing computer program development platforms and well-known programming methods.

[0121] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such equivalent variations or substitutions are intended to be encompassed within the scope of the claims of this application.
