Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of automobile air conditioning, in particular to an automobile air conditioning HVAC system and a vehicle. BACKGROUND
[0002] The automobile passenger cabin is a sealed space, and an air conditioning system is needed to realize functions such as refrigeration, heating, dehumidification, air supply and the like in the vehicle. The front and rear HVACs in the air conditioning system are responsible for heat exchange, air filtration, bacteria inhibition and removal, air supply temperature adjustment, air supply direction and air supply volume adjustment and the like for the passenger cabin to provide different air conditioning requirements. The front HVAC has evolved from the initial single refrigeration, single air volume and single mode to the current four-temperature-zone, four-mode and four-air-volume independent control, and the function is more and more perfect and can provide different air conditioning temperature zones, air volumes and modes for the passenger cabin. The rear HVAC generally still adopts a cold and warm integrated structure with a single temperature zone, a single mode and a single air volume. The front and rear HVACs in the current industry can at most realize five-temperature-zone, five-mode and five-air-volume independent control functions, i.e., five temperature zones for the main driver, the assistant driver, the second-row left seat, the second-row right seat and the third-row seat, which can only realize left and right partitioning. CONTENT OF THE UTILITY MODEL
[0003] The purpose of the embodiment of the present application is to provide an automobile air conditioning HVAC system for realizing up and down partitioning of the temperature in the vehicle cabin.
[0004] In a first aspect, the present application provides an automobile air conditioning HVAC system, comprising: a first HVAC module, the first HVAC module comprising a first face blowing micro motor assembly, a first foot blowing micro motor assembly and a first air outlet assembly; the first face blowing micro motor assembly comprising a first face blowing micro motor and a first face blowing mixed micro motor; the first foot blowing micro motor assembly comprising a first foot blowing micro motor and a first foot blowing mixed micro motor; the first air outlet assembly comprising a first face blowing air outlet and a first foot blowing air outlet; the first face blowing micro motor is configured to control the opening and closing angle and position of the corresponding air door of the first face blowing air outlet and adjust the air volume of the first face blowing air outlet; the first face blowing mixed micro motor is configured to control the air supply temperature of the first face blowing air outlet; the first foot blowing micro motor is configured to control the opening and closing angle and position of the corresponding air door of the first foot blowing air outlet and adjust the air volume of the first foot blowing air outlet; and the first foot blowing mixed micro motor is configured to control the air supply temperature of the first foot blowing air outlet.
[0005] In the above solution, the first HVAC module controls the surface and foot temperatures of a single seat, such as the driver's seat or the passenger seat, through independent first surface-blowing hybrid micro motor and first foot-blowing hybrid micro motor (e.g., 20°C for the driver's surface and 26°C for the feet). This solves the problem that traditional car air conditioners can only be divided into left and right zones and cannot independently adjust the temperature of the upper and lower parts. Furthermore, by controlling the damper angle through the first surface-blowing micro motor and the first foot-blowing micro motor, the air volume of the surface-blowing and foot-blowing can also be independently adjusted (e.g., 3 levels of air volume for the driver's surface and 3 levels of air volume for the feet), thereby achieving independent adjustment of the upper and lower temperatures and meeting the differentiated needs of different body parts.
[0006] As an optional approach, the first HVAC module further includes a defrosting micro motor, and the first air outlet assembly further includes a defrosting air outlet; the defrosting micro motor is used to control the opening and closing angle and position of the damper corresponding to the defrosting air outlet, and to adjust the air volume of the defrosting air outlet; the first blowing and mixing micro motor is also used to control the air supply temperature of the defrosting air outlet.
[0007] In the above solution, the defrosting micro motor has high priority and can quickly control the opening angle and position of the corresponding damper of the defrosting air vent, rapidly adjust the air volume of the defrosting air vent, and promptly guide a large amount of hot air to the windshield to quickly melt frost and dissipate fog, ensuring clear visibility for the driver.
[0008] As an optional embodiment, the first HVAC module further includes a second surface blowing micro motor, a second foot blowing micro motor, and a second surface blowing and foot blowing hybrid micro motor; the first air outlet assembly further includes a second surface blowing air outlet and a second foot blowing air outlet; the second surface blowing micro motor is used to control the opening and closing angle and position of the damper corresponding to the second surface blowing air outlet, and adjust the air volume of the second surface blowing air outlet; the second foot blowing micro motor is used to control the opening and closing angle and position of the damper corresponding to the second foot blowing air outlet, and adjust the air volume of the second foot blowing air outlet; the second surface blowing and foot blowing hybrid micro motor is used to control the air supply temperature of the second surface blowing air outlet and the second foot blowing air outlet.
[0009] In the above solution, the air vents on the face and feet of the second row of seats are controlled by the second air blowing micro motor and the second foot blowing micro motor, respectively, so that the temperature and air volume of each seat can be adjusted independently, solving the problem that traditional air conditioners can only control the temperature of the second row uniformly.
[0010] As an optional mode, the first HVAC module further comprises a second face blowing micro motor assembly and a second foot blowing micro motor assembly; the second face blowing micro motor assembly comprises a second face blowing micro motor and a second face blowing mixed micro motor; the second foot blowing micro motor assembly comprises a second foot blowing micro motor and a second foot blowing mixed micro motor; the first air outlet assembly further comprises a second face blowing air outlet and a second foot blowing air outlet; the second face blowing micro motor is used to control the opening and closing angle and position of the corresponding air door of the second face blowing air outlet, and adjust the air volume of the second face blowing air outlet; the second face blowing mixed micro motor is used to control the air supply temperature of the second face blowing air outlet; the second foot blowing micro motor is used to control the opening and closing angle and position of the corresponding air door of the second foot blowing air outlet, and adjust the air volume of the second foot blowing air outlet; the second foot blowing mixed micro motor is used to control the air supply temperature of the second foot blowing air outlet.
[0011] In the above scheme, the extended second face blowing micro motor assembly and the second foot blowing micro motor assembly have the same composition and function as the first face blowing micro motor assembly and the second foot blowing micro motor assembly, and can realize independent adjustment of the temperature of the upper and lower seats of the second row, and increase the comfort of the second row.
[0012] As an optional mode, the system comprises two first HVAC modules, and the two first HVAC modules control the left and right temperature zones in the vehicle cabin respectively.
[0013] In the above scheme, one first HVAC module controls the independent adjustment of the temperature, mode and air volume of the left seat, and the other first HVAC module controls the independent adjustment of the temperature, mode and air volume of the right seat. Under the condition that a single first HVAC module realizes temperature zoning of the upper and lower seats, the left and right temperature zones are further expanded, the number of temperature zones is upgraded, and the foundation is laid for supporting the vehicle to realize multiple temperature zones such as eight temperature zones or even more.
[0014] As an optional mode, the two first HVAC modules are integrated into a centrally-mounted double-layer flow structure, and the centrally-mounted double-layer flow structure comprises an inner and outer circulation air flow channel, and a partition plate is arranged in the middle of the inner and outer circulation air flow channel to realize layered isolation of the inner circulation air flow and the outer circulation air flow.
[0015] In the above scheme, the partition plate physically isolates the inner and outer circulation air flow channels, avoids mixing of fresh air (outer circulation) and vehicle circulating air, reduces energy waste, and in addition, the centrally-mounted structure can save space and provide layout space for the foot rest of the front passenger seat of a high-end vehicle.
[0016] As an optional approach, the system further includes: a second HVAC module; the second HVAC module includes a temperature damper micro motor, a mode damper micro motor, and a second air outlet assembly, wherein the temperature damper micro motor includes a left temperature damper micro motor and a right temperature damper micro motor, and the mode damper micro motor includes a left mode damper micro motor and a right mode damper micro motor; the second air outlet assembly includes a left ceiling-mounted air outlet, a left foot-mounted air outlet, a right ceiling-mounted air outlet, and a right foot-mounted air outlet; the left temperature damper micro motor is used to control the air supply temperature of the left ceiling-mounted air outlet and the left foot-mounted air outlet; the right temperature damper micro motor is used to control the air supply temperature of the right ceiling-mounted air outlet and the right foot-mounted air outlet; the left mode damper micro motor is used to control the air supply direction of the left air outlet (facing and feet); and the right mode damper micro motor is used to control the air supply direction of the right air outlet (facing and feet).
[0017] In the above solution, the second HVAC module can achieve temperature zoning for the rear seats, such as the left and right sides of the third row, improving rear passenger comfort. Together with the first HVAC module, it enhances the vehicle's temperature zone configuration capabilities, allowing for independent adjustment of temperature, mode, and airflow in each zone, significantly improving overall vehicle performance.
[0018] Alternatively, the second HVAC module may also include a blower, a speed control module, and a PTC air heater; the speed control module controls the speed of the blower to regulate the airflow. The temperature damper micro-motor regulates the proportion of airflow passing through the PTC air heater to adjust the outlet air temperature.
[0019] In the above solution, the PTC heater quickly raises the air temperature through an electric heating element, which is especially suitable for electric vehicles or cold environments. It does not rely on the engine's waste heat, allowing rear passengers to quickly receive hot air and improve their experience.
[0020] As an optional approach, the system also includes: an air conditioning controller; both the first HVAC module and the second HVAC module are electrically connected to the air conditioning controller.
[0021] In the above scheme, the air conditioning controller acts as a central hub, uniformly receiving user commands and sensor data from the control interface, coordinating the operation of the first HVAC module and the second HVAC module, and avoiding response delays caused by decentralized control.
[0022] Secondly, this application provides a vehicle including the automotive air conditioning (HVAC) system described in the first aspect.

[0038] Automotive HVAC refers to the heating, ventilation, and air conditioning system of a vehicle. With the continuous development of the automotive industry, consumers have increasingly higher demands for the comfort and functionality of automotive air conditioning systems. Traditional automotive air conditioning systems often have limitations in temperature regulation and airflow control, making it difficult to meet the personalized needs of different passengers for the in-vehicle environment. For example, in some situations, the driver and passengers may have different temperature requirements for the face and feet. If the foot temperature is met, making the feet warm, the breathing point near the face may become too hot, causing stuffiness and drowsiness. Conversely, if the face temperature is met, the driver's feet may become cold, affecting driving comfort. Figure 1 As shown, Figure 1 The diagram below shows the distribution of the five temperature zones in the vehicle in the comparative embodiment. It can be seen that the existing air conditioning system can only achieve a maximum of five temperature zones in the vehicle (driver's seat 1, passenger seat 2, second row left 3, second row right 4, and third row 5), but it cannot achieve precise independent vertical adjustment, resulting in a poor passenger experience.
[0039] Reference Figure 2 , Figure 2 This is a schematic diagram of a first structure of a first HVAC module in an automotive air conditioning HVAC system provided in an embodiment of this application.
[0040] The automotive air conditioning HVAC system includes a first HVAC module, which includes a first surface blowing micro-motor assembly, a first foot blowing micro-motor assembly, and a first air vent assembly. The first surface blowing micro-motor assembly includes a first surface blowing micro-motor 100 and a first surface blowing hybrid micro-motor 101. The first foot blowing micro-motor assembly includes a first foot blowing micro-motor 102 and a first foot blowing hybrid micro-motor 103. The first air vent assembly includes a first surface blowing vent and a first foot blowing vent. The first surface blowing micro-motor 100 is used to control the opening and closing angle and position of the damper corresponding to the first surface blowing vent, and to adjust the air volume of the first surface blowing vent. The first surface blowing hybrid micro-motor 101 is used to control the air supply temperature of the first surface blowing vent. The first foot blowing micro-motor 102 is used to control the opening and closing angle and position of the damper corresponding to the first foot blowing vent, and to adjust the air volume of the first foot blowing vent. The first foot blowing hybrid micro-motor 103 is used to control the air supply temperature of the first foot blowing vent.
[0041] The first air-blowing micro motor 100 is used to control the opening angle and position of the damper corresponding to the first air-blowing vent. By precisely adjusting the opening angle and position of the damper, the airflow of the first air-blowing vent can be effectively adjusted. For example, when passengers require a larger airflow, the first air-blowing micro motor 100 can open the damper to a larger angle, allowing more air to enter the vehicle through the first air-blowing vent; conversely, when a smaller airflow is required, the opening angle of the damper is reduced accordingly.
[0042] The first air-blowing mixing micro-motor 101 is used to control the air supply temperature of the first air-blowing vent. The first air-blowing mixing micro-motor 101 can achieve precise control of the air supply temperature of the first air-blowing vent by adjusting the mixing ratio of hot and cold air. For example, when passengers need a higher air-blowing temperature, the first air-blowing mixing micro-motor 101 can increase the proportion of hot air; when a lower temperature is needed, it can increase the proportion of cold air.
[0043] The first foot blowing micro motor 102, the first face blowing micro motor 100, the first foot blowing mixed micro motor 103, and the first face blowing mixed micro motor 101 have similar functions, and are used to individually control the foot blowing air volume and temperature, thereby realizing the zoning of upper and lower temperatures.
[0044] The first face-blowing vent is used to deliver air to the passenger's face area, while the first foot-blowing vent is used to deliver air to the passenger's foot area. Through the coordinated operation of the first face-blowing micro-motor assembly and the first foot-blowing micro-motor assembly, the first face-blowing vent and the first foot-blowing vent can achieve independent adjustment of air volume and temperature, providing support for expanding the temperature range of the entire vehicle.
[0045] The first face blowing micro motor assembly and the first foot blowing micro motor assembly jointly control a single seat, enabling independent adjustment of the upper and lower temperature zones. For example, if the first face blowing micro motor assembly and the first foot blowing micro motor assembly control the driver's seat, the driver can set the face blowing temperature to 22°C and the air volume to level 3 according to their own habits, and set the foot blowing temperature to 25°C and the air volume to level 2.
[0046] In the above solution, the first HVAC module controls the surface and foot temperatures of a single seat, such as the driver's seat or the passenger seat, through independent first surface-blowing hybrid micro motor 101 and first foot-blowing hybrid micro motor 103 (e.g., 20°C for the driver's surface and 26°C for the feet). This solves the problem that traditional car air conditioners can only be divided into left and right zones and cannot independently adjust the temperature of the upper and lower parts. Furthermore, by controlling the damper angle through the first surface-blowing micro motor 100 and the first foot-blowing micro motor 102, the air volume of the surface-blowing and foot-blowing can also be independently adjusted (e.g., 3 levels of air volume for the driver's surface and 3 levels of air volume for the feet), thereby achieving independent adjustment of the upper and lower temperatures and meeting the differentiated needs of different body parts.
[0047] In some embodiments, as shown in Figure 3. Figure 3 This is a schematic diagram of a second structure of the first HVAC module in an automotive air conditioning HVAC system provided in an embodiment of this application.
[0048] The first HVAC module also includes a defrost micro motor 104, and the first air outlet assembly also includes a defrost air outlet; the defrost micro motor 104 is used to control the opening and closing angle and position of the damper corresponding to the defrost air outlet, and to adjust the air volume of the defrost air outlet; the first blowing and mixing micro motor 101 is also used to control the air supply temperature of the defrost air outlet.
[0049] Defrosting is a crucial component for ensuring driving safety. The defrosting micro-motor 104 controls the opening angle and position of the corresponding damper of the defrosting vent, adjusting the airflow. The defrosting vent is integrated into the first vent assembly, independent of the first airflow surface and first foot vents, directly supplying air to the inside of the windshield. The first airflow surface mixing micro-motor 101 simultaneously controls the airflow temperature from the defrosting vent, achieving precise temperature regulation by adjusting the mixing ratio of hot and cold air. The defrosting micro-motor 104 can have a higher priority than other micro-motors to ensure driving safety.
[0050] The defrosting micro motor 104 adopts high-priority control logic. When frost or fog is detected on the windshield (such as in a low-temperature and high-humidity environment), the defrosting damper opening can be increased to the maximum in a short time. At the same time, the first blowing surface mixing micro motor 101 increases the air supply temperature to quickly melt the frost and restore the driver's visibility.
[0051] In the above solution, the defrosting micro motor 104 has high priority and can quickly control the opening angle and position of the defrosting air vent corresponding to the damper, rapidly adjust the air volume of the defrosting air vent, and promptly guide a large amount of hot air to the windshield to quickly melt frost and dissipate fog, ensuring clear visibility for the driver.
[0052] In some embodiments, refer to Figure 4 , Figure 4 This is a schematic diagram of a third structure of the first HVAC module in the automotive air conditioning HVAC system provided in this application embodiment. The first HVAC module further includes a second surface blowing micro motor 105, a second foot blowing micro motor 106, and a second surface blowing and foot blowing hybrid micro motor 107; the first air outlet assembly further includes a second surface blowing air outlet and a second foot blowing air outlet; the second surface blowing micro motor 105 is used to control the opening and closing angle and position of the damper corresponding to the second surface blowing air outlet, and to adjust the air volume of the second surface blowing air outlet; the second foot blowing micro motor 106 is used to control the opening and closing angle and position of the damper corresponding to the second foot blowing air outlet, and to adjust the air volume of the second foot blowing air outlet; the second surface blowing and foot blowing hybrid micro motor 107 is used to control the air supply temperature of the second surface blowing air outlet and the second foot blowing air outlet.
[0053] The purpose of this embodiment, which includes a second facial blowing micro-motor 105, a second foot blowing micro-motor 106, and a second facial and foot blowing hybrid micro-motor 107, is to improve the comfort of rear passengers and address the issue that second-row passengers typically can only share the air conditioning settings of the driver or front passenger seat and cannot independently adjust the temperature and airflow of the facial and foot blowing systems. For example, when children are in the second row, they may need a lower facial blowing temperature to avoid direct airflow, while adult passengers prefer a higher foot blowing temperature. This "one-size-fits-all" control method results in significantly lower rear-seat comfort compared to the front seats, a contradiction that is particularly pronounced in multi-seat vehicles.
[0054] The second blowing micro motor 105 is used to control the opening and closing angle of the air door corresponding to the second blowing air outlet, and adjust the blowing air volume of the left or right rear seat, such as the left or right side of the second row.
[0055] The second foot blowing micro motor 106 is used to control the opening and closing angle of the air door corresponding to the second foot blowing air outlet, and adjust the foot blowing air volume of the rear left seat or the rear right seat, such as the second row left or the second row right.
[0056] The second air blowing and foot blowing mixing micro motor 107 is used to independently control the air blowing and foot blowing temperature of the rear left seat or the rear right seat, such as the second row left or the second row right seat, by adjusting the mixing ratio of hot and cold air.
[0057] The second face-blowing vent and the second foot-blowing vent are integrated into the first vent assembly, respectively delivering air to the face and foot areas of the left or right rear seats. This allows each rear seat to have its own dedicated temperature zone. However, unlike the temperature zones controlled by the first face-blowing micro-motor assembly and the first foot-blowing micro-motor assembly, they cannot be divided into upper and lower temperature zones. For example, if the second face-blowing micro-motor 105, the second foot-blowing micro-motor 106, and the second face-blowing and foot-blowing hybrid micro-motor 107 control the left-side seats in the second row, then the left-side passengers in the second row can independently set the face-blowing and foot-blowing parameters. For example: face-blowing temperature 24℃ (level 2), foot-blowing temperature 24℃ (level 5).
[0058] In the above solution, the air vents for blowing on the face and feet of one side of the second row of seats are controlled by the second air blowing micro motor 105 and the second air blowing micro motor 106, respectively, so that the temperature and air volume of each seat can be adjusted independently, solving the problem that traditional air conditioners can only control the temperature of the second row uniformly.
[0059] In some embodiments, the first HVAC module further includes a second surface blowing micro motor assembly and a second foot blowing micro motor assembly; the second surface blowing micro motor assembly includes a second surface blowing micro motor 105 and a second surface blowing hybrid micro motor; the second foot blowing micro motor assembly includes a second foot blowing micro motor 106 and a second foot blowing hybrid micro motor; the first air outlet assembly further includes a second surface blowing air outlet and a second foot blowing air outlet; the second surface blowing micro motor 105 is used to control the opening and closing angle and position of the damper corresponding to the second surface blowing air outlet, and adjust the air volume of the second surface blowing air outlet; the second surface blowing hybrid micro motor is used to control the air supply temperature of the second surface blowing air outlet; the second foot blowing micro motor 106 is used to control the opening and closing angle and position of the damper corresponding to the second foot blowing air outlet, and adjust the air volume of the second foot blowing air outlet; the second foot blowing hybrid micro motor is used to control the air supply temperature of the second foot blowing air outlet.
[0060] To further enhance the comfort of rear passengers, in this embodiment, the second surface-blowing micro-motor assembly and the second foot-blowing micro-motor assembly used to control the rear seats can also adopt the same mechanism and structure as the first surface-blowing micro-motor assembly and the first foot-blowing micro-motor assembly, enabling independent temperature adjustment for each rear seat, just like the driver's or passenger's seat. Specific details are described in the descriptions of the first surface-blowing micro-motor assembly and the first foot-blowing micro-motor assembly, and will not be repeated here.
[0061] In the above scheme, the extended second blowing surface micro motor assembly and the second blowing foot micro motor assembly have the same composition and function as the first blowing surface micro motor assembly and the second blowing foot micro motor assembly, which can realize independent adjustment of the upper and lower temperature of the second row of single-side seats, thereby increasing the comfort of the second row.
[0062] In some embodiments, the system includes two first HVAC modules, which control the left and right temperature zones inside the vehicle interior, respectively.
[0063] The system includes two first HVAC modules. One first HVAC module is responsible for controlling the driver's seat area or the driver's seat and the left side of the second row; the other first HVAC module is responsible for controlling the passenger seat area or the passenger seat and the right side of the second row.
[0064] If both first HVAC modules adopt the second blowing micro motor 105, the second blowing micro motor 106, and the second blowing micro motor 107, which are different from the first blowing micro motor assembly and the first blowing micro motor assembly in the aforementioned embodiments, then the first and second rows of the vehicle can achieve a maximum of six temperature zones, namely, driver's side blowing surface, driver's side blowing foot, passenger side blowing surface, passenger side blowing foot, second row left, and second row right. The temperature of these six temperature zones can be controlled independently, and the air volume of the driver's side blowing surface temperature zone and the driver's side blowing foot temperature zone are synchronized, as are the air volume of the passenger side blowing surface temperature zone and the passenger side blowing foot temperature zone.
[0065] If both first HVAC modules adopt the second surface blowing micro-motor assembly and the second foot blowing micro-motor assembly, which are similar to the first surface blowing micro-motor assembly and the first foot blowing micro-motor assembly in the aforementioned embodiments, then the first row and the second row of the vehicle can achieve up to eight temperature zones, namely, the driver's side surface blowing, the driver's side foot blowing, the passenger's side surface blowing, the passenger's side foot blowing, the second row left surface blowing, the second row left foot blowing, the second row right surface blowing, and the second row right foot blowing. The temperature of these eight temperature zones can be controlled independently.
[0066] In the above scheme, one first HVAC module controls the independent adjustment of the temperature, mode, and airflow of the left seat, and another first HVAC module controls the independent adjustment of the temperature, mode, and airflow of the right seat. With the single first HVAC module realizing the upper and lower temperature zones, the left and right temperature zones are further expanded, upgrading the number of temperature zones and laying the foundation for supporting the whole vehicle to realize multiple temperature zones, such as eight temperature zones or even more.
[0067] In some embodiments, refer to Figure 5 , Figure 5 This is a schematic diagram of a centrally located dual-layer flow structure of two first HVAC modules in an automotive air conditioning HVAC system provided in this application embodiment. The two first HVAC modules are integrated into a centrally located dual-layer flow structure. The centrally located dual-layer flow structure includes internal and external circulation airflow channels. A partition is set in the middle of the internal and external circulation airflow channels to achieve layered isolation between the internal circulation airflow and the external circulation airflow.
[0068] The two first HVAC modules can be either two separate modules or integrated together.
[0069] In the centrally located structural design, the two first HVAC modules are integrated as a single unit on the left and right, and installed below the central passage of the vehicle.
[0070] Figure 5The blue arrows indicate the direction of the external airflow, and the red arrows indicate the direction of the internal airflow. The external airflow channel is used to independently introduce fresh air, while the internal airflow channel is used to directly circulate the air inside the vehicle; they are separated by a partition. The internal airflow channel can integrate a CO sensor. When the detected carbon dioxide content in the internal airflow is too high, it can automatically switch the circulation mode, activating the external airflow mode to introduce fresh air and ensure air cleanliness and quality.
[0071] In this embodiment, after the two first HVAC modules are integrated into a left / right unit, the position of the first air outlet assembly is referenced. Figure 6 , Figure 6 A schematic diagram showing the distribution of the first air vent assemblies on two first HVAC modules in an automotive air conditioning HVAC system provided in this application embodiment. Figure 6 (Only one first air outlet assembly of a first HVAC module is shown in the image; the first air outlet assemblies of two first HVAC modules are arranged symmetrically.) As one implementation, the first air outlet can be designed to include two air outlets: a first left-side air outlet and a first middle air outlet. The airflow of the first left-side air outlet and the first middle air outlet is uniformly controlled by the first air-blowing micro motor 100, and the temperature is uniformly controlled by the first air-blowing mixing micro motor 101. The other first HVAC module is similarly controlled.
[0072] In the above solution, the partition physically isolates the internal and external airflow channels, preventing fresh air (external circulation) from mixing with the internal air circulation, thus reducing energy waste. In addition, the centrally located structure saves space and frees up layout space for the passenger footrest in high-end models.
[0073] In some embodiments, refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the second HVAC module in the automotive air conditioning HVAC system provided in this application embodiment. The automotive air conditioning HVAC system further includes: a second HVAC module; the second HVAC module includes a temperature damper micromotor, a mode damper micromotor, and a second air vent assembly, wherein the temperature damper micromotor includes a left temperature damper micromotor 201 and a right temperature damper micromotor 203, and the mode damper micromotor includes a left mode damper micromotor 202 and a right mode damper micromotor 204; the second air vent assembly includes a left ceiling air vent 205, a left foot air vent 206, and a right ceiling air vent 207. The system includes a front air vent 207 and a right foot air vent 208; a left temperature damper micro motor 201 controls the air supply temperature of the left ceiling front air vent 205 and the left foot air vent 206; a right temperature damper micro motor 203 controls the air supply temperature of the right ceiling front air vent 207 and the right foot air vent 208; a left mode damper micro motor 202 controls the front and foot air direction of the left air outlet; and a right mode damper micro motor 204 controls the front and foot air direction of the right air outlet.
[0074] The left temperature damper micro motor 201 is connected to the temperature regulating dampers of the left ceiling air vent 205 and the left foot air vent 206. By precisely controlling the opening of the dampers, the mixing ratio of hot and cold air entering the left ceiling air vent 205 and the left foot air vent 206 is adjusted, thereby controlling the air supply temperature of these two vents. The right temperature damper micro motor 203 works similarly.
[0075] The left mode damper micro motor 202 connects to the mode adjustment damper of the left ceiling air vent 205 and the left foot air vent 206, controlling the airflow direction by changing the position of the damper. The right mode damper micro motor 204 works similarly.
[0076] The second HVAC module is suitable for zoned control of the left and right temperature zones in the rear.
[0077] Different temperature zone requirements can be achieved by the coordinated operation of the first HVAC module and the second HVAC module. For example, the first and second rows can be configured with two first HVAC modules to achieve six or eight temperature zones, and the third row can be configured with a second HVAC module. Alternatively, the first row can be configured with two first HVAC modules to achieve four temperature zones, and the second and third rows can each be configured with one second HVAC module to achieve four temperature zones. Those skilled in the art can make adjustments according to actual design requirements.
[0078] In the above solution, the second HVAC module can achieve temperature zoning for the rear seats, such as the left and right sides of the third row, improving rear passenger comfort. Together with the first HVAC module, it enhances the vehicle's temperature zone configuration capabilities, allowing for independent adjustment of temperature, mode, and airflow in each zone, significantly improving overall vehicle performance.
[0079] In some embodiments, the second HVAC module further includes a blower 209, a speed control module 210, and a PTC heater 211; the speed control module 210 is used to control the rotational speed of the blower 209 to achieve airflow regulation. A temperature damper micro-motor is used to adjust the proportion of airflow passing through the PTC heater 211 to regulate the outlet air temperature.
[0080] Blower 209 is the power source for air circulation, responsible for drawing air into the second HVAC module and delivering it to various air outlets through ducts, providing sufficient airflow to the air conditioning system to meet ventilation and air conditioning needs under different operating conditions. Speed control module 210 is connected to blower 209, precisely controlling its speed by adjusting the voltage or current input to blower 209. Changes in speed directly affect the airflow through the second HVAC module, thus enabling flexible adjustment of airflow. A PTC heater is used to heat the passing air to increase the outlet air temperature.
[0081] In the above solution, the PTC heater 211 quickly raises the air temperature through an electric heating element, which is especially suitable for electric vehicles or cold environments. It does not rely on the waste heat of the engine, allowing rear passengers to quickly obtain hot air and improve their experience.
[0082] In some embodiments, the system further includes: an air conditioning controller; both the first HVAC module and the second HVAC module are electrically connected to the air conditioning controller.
[0083] After equipping the vehicle with the first and second HVAC modules, the vehicle can achieve independent control of at least eight temperature zones, six modes, and six airflow rates, all controlled by the air conditioning controller. The air conditioning controller can calculate the outlet air temperature, airflow rate, and airflow mode for each seat occupant based on their individual temperature, mode, and airflow settings, and uses a fuzzy PID control algorithm to manage the vehicle's air conditioning system. The fuzzy PID control algorithm uses a set deviation e(t) = T 目标 -T 实测 Continuously optimize and adjust until the parameters precisely match the user's settings, including T. 目标 This indicates the target temperature set by the occupants, T. 实测 This represents the actual temperature of the area inside the vehicle cabin as collected by the sensor. Specifically, when using a fuzzy PID control algorithm, one possible correction coefficient is...
[0084] The air conditioning controller can also be designed with an energy-saving mode. When an empty seat is detected, the corresponding area is turned off, and ventilation is only provided to occupied seats, reducing the cooling and heating power consumption of the whole vehicle and lowering the overall energy consumption of the vehicle.
[0085] like Figure 8 As shown, Figure 8 This is a schematic diagram of an air conditioning control interface that works in conjunction with the first HVAC module of this application. It can be seen that within the respective temperature zones for the driver and passenger seats, the temperature for blowing onto the face and feet can be set independently, and the airflow and mode can be adjusted separately. Figure 9 As shown, Figure 9 This is a schematic diagram of an air conditioning control interface that works in conjunction with the second HVAC module of this application. It can be seen that the airflow, mode, and temperature can be set independently within each of the left and right temperature zones.
[0086] In the above scheme, the air conditioning controller acts as a central hub, uniformly receiving user commands and sensor data from the control interface, coordinating the operation of the first HVAC module and the second HVAC module, and avoiding response delays caused by decentralized control.
[0087] This application provides a vehicle including the automotive air conditioning (HVAC) system of any of the above embodiments.
[0088] The above are merely embodiments of this application and are not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
