This results in problems such as cold air blowing directly onto the body and uneven temperature distribution.

[0066] In the embodiments of the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0067] In the embodiments of the present application, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0068] Refer Figures 1 to 9 As shown, the embodiments of the present invention disclose an air outlet assembly for at least one of the rear occupant space and the middle row occupant space of a vehicle. The air outlet assembly includes a plurality of air outlets, at least some of the air outlets have a plurality of air outlet areas, and each of the air outlet areas has an independent air-diffusing hole configuration, so that the plurality of air outlet areas send air to different target areas of the corresponding occupant space, and the target areas are adapted to be divided according to the body parts of the occupants.

[0069] The air-diffusing hole configuration of each of the air outlet areas may include the number of air-diffusing holes in the area, the air outlet area size of a single air-diffusing hole, the orientation or deflection angle of the air-diffusing holes, etc. By having an independent air-diffusing hole configuration for each of the air outlet areas, the air outlet characteristics of each air outlet area can be individually regulated.

[0070] In the aforementioned air outlet assembly, at least some of the multiple air outlets have multiple air outlet zones. Each air outlet zone has an independent diffuser configuration. Through the independent diffuser configuration of multiple air outlet zones, the coordinated output of different airflow parameters within the same air outlet can be achieved, allowing the multiple air outlet zones to deliver air to different target areas of the corresponding passenger space, simultaneously meeting the differentiated temperature requirements of different body parts of the occupants. Each air outlet zone is divided into target areas based on the occupant's body position, allowing the airflow to naturally conform to the contours of the human body, avoiding the discomfort caused by direct airflow. At the same time, because the air delivery is more targeted, it helps to reduce ineffective airflow circulation and improve system energy efficiency. In summary, the solution of this application can at least improve the problem of large differences in perceived temperature in at least one of the different areas of the vehicle in some scenarios, such as the front row, middle row, and rear row, thereby improving the occupant's physical comfort.

[0071] At least some of the multiple air outlets have multiple air outlet zones. This can be understood as, in specific implementation, some air outlets can adopt a multi-zone design, while the rest can retain a single-zone structure, forming a hybrid layout of "main control air outlet + auxiliary air outlet". This allows for dynamic adaptation to needs based on differences in passenger cabin space. For example, the frequently used rear row area can be fully zoned, while the non-core middle row area can retain a single-zone air outlet structure, which is beneficial for cost optimization. Alternatively, all air outlets can adopt a multi-zone design, which is beneficial for precise control of perceived temperature.

[0072] In some alternative implementations, the air diffuser configuration includes the air outlet area of ​​the air diffuser, and in at least some of the plurality of air outlet areas, the air outlet area of ​​the air diffuser is different.

[0073] By adjusting the air outlet area of ​​the diffuser, for example, the air outlet area of ​​the diffuser is 10mm. 2- 30mm 2 Within a certain range, precise control of airflow speed can be achieved. A larger outlet area of ​​the diffuser hole can create a low-speed diffused airflow, while a smaller outlet area can generate a relatively high-speed directional airflow. The difference in the outlet area of ​​the diffuser hole reduces the perceived temperature difference.

[0074] In some alternative implementations, the ventilation vent configuration includes the number of ventilation vents, and at least some of the multiple air outlet areas have a different number of ventilation vents. In specific implementations, the number of ventilation vents is positively correlated with the area of ​​the air outlet area to achieve optimized matching of heat loads for different body parts. For example, the number of ventilation vents in the air outlet area corresponding to the knee is greater than the number of ventilation vents in the air outlet area corresponding to the face, thus more accurately matching the heat load requirements of different body parts.

[0075] In some optional embodiments, the air dispersion hole configuration includes the deflection angle of the air dispersion holes in a preset reference coordinate system corresponding to the air outlet. Among the multiple air outlet areas, the deflection angles of the air dispersion holes in at least some of the air outlet areas are different. For example, in a specific implementation, a deflection angle of -5° to 20° can be set to make the airflow in the head area rise to avoid direct blowing, and the airflow in the knee area press down to form a hot air curtain, which can improve the airflow conformity and reduce or avoid discomfort caused by direct blowing.

[0076] It can be understood that the air outlet area of the aforementioned air dispersion holes, the number of air dispersion holes, and the deflection angle of the air dispersion holes in the preset reference coordinate system corresponding to the air outlet can be adjusted independently or in coordination.

[0077] In some optional embodiments, the air outlet includes a rectangular parallelepiped-shaped air dispersion plate, and the air outlet area is formed on the air dispersion plate; the air dispersion plate has a length direction, a width direction, and a normal direction that are perpendicular to each other. The length direction is adapted to point to the vehicle's due front, and the width direction is adapted to point to the side window;

[0078] See Figure 3 As shown, the normal direction of the air dispersion plate is adapted to form an installation angle α with the ground of the corresponding occupant space, and the angle value of the installation angle α is 65° - 70°.

[0079] The normal direction here can be understood as the thickness direction of the rectangular parallelepiped-shaped air dispersion plate. The installation angle of the air dispersion plate of 65° - 70° makes the airflow form the best incident angle with the occupant's torso. The cold air diffuses downward obliquely along the normal direction, forming a gradient coverage to avoid direct blowing on the face. At this angle, the airflow attenuation rate is small, and the wind speed is stable in the comfortable range.

[0080] See Figure 1 and Figure 6 As shown, in some optional embodiments, the air outlet component includes a rear air outlet, which is adapted to be arranged at the roof corresponding to the rear seating space and includes at least two of the following air outlet areas:

[0081] The first air outlet area is used to supply air to the first target area of the rear occupant space, and the first target area is a predetermined area corresponding to the occupant's feet, calves, and thighs;

[0082] The second air outlet area is used to supply air to the second target area of the rear occupant space, and the second target area is a predetermined area corresponding to the occupant's neck, chest, abdomen, and the arm on the side away from the window;

[0083] ]The third air outlet area is used to supply air to the third target area of the rear occupant space, and the third target area is a predetermined area corresponding to the occupant's arm on the side close to the window, calves, and thighs;

[0084] The first, second, and third air outlet areas of the rear air vent have independent ventilation holes.

[0085] By independently configuring ventilation holes, airflow distribution is optimized for the feet, torso, and window-side limbs, creating a gradient temperature field to prevent localized overheating or cooling. For example, low-speed infiltration airflow is used in the foot area, medium airflow is maintained in the core torso area, and an airflow barrier is formed at the window side. This allows for differentiated temperature zone control. Based on the different temperature sensitivities of different body parts, the neck area uses a dense array of holes to increase airflow, while direct airflow is reduced in the feet area, resulting in a more ergonomic and thermally comfortable experience. High-level air supply shortens the airflow path, balancing the temperature difference between the front and rear rows more quickly compared to traditional B-pillar air outlet solutions, and reducing ineffective circulating airflow.

[0086] In some optional embodiments, the number of air diffusers in the first air outlet area is greater than the number of air diffusers in the third air outlet area, and the number of air diffusers in the third air outlet area is greater than the number of air diffusers in the second air outlet area, to ensure the cooling effect on the feet and calves. For example, in some optional embodiments, the number of air diffusers in the first, second, and third air outlet areas satisfies (8-12):1:(1.2-2), that is, if the number of air diffusers in the second air outlet area is N, the number of air diffusers in the first air outlet area is 8N-12N, and the number of air diffusers in the third air outlet area is 1.2N-2.0N. For example, in specific implementations, the number of air diffusers in the first, second, and third air outlet areas can satisfy 10:1:1.5, or 8:1:1.2, 9:1:1.6, etc.

[0087] The first air outlet area (feet / legs) features a high number of perforations to ensure basic airflow coverage. Combined with a 65°-70° tilt angle, this allows airflow to rise naturally, creating a low-speed infiltration airflow and utilizing the natural upward movement of hot air to achieve gradient temperature control. The second air outlet area, the torso area, has a low number of perforations to reduce direct contact with cold air. The third air outlet area, the window side, has a medium number of perforations to balance insulation and ventilation needs, creating zoned control that caters to the different thermal sensitivities of the human body. The differentiated perforation count reduces airflow mixing losses, and the high-level airflow shortens the airflow path, improving system energy efficiency.

[0088] In some optional embodiments, the air outlet area of ​​the diffuser holes in the first air outlet area and the third air outlet area is smaller than the air outlet area of ​​the diffuser holes in the second air outlet area. For example, in some optional embodiments, the air outlet area of ​​the diffuser holes in the first air outlet area and the third air outlet area is A1, and the air outlet area of ​​the diffuser holes in the second air outlet area is A2, satisfying: A2 / A1 = 2 - 2.5. For example, the value of A2 / A1 can be 2, 2.05, 2.1, 2.15, 2.25, 2.3, 2.5, etc.

[0089] In summer clothing, some parts of the human body are uncovered, such as the calves, part of the thighs, the head, the forearms, etc., while the chest to the thighs are usually covered with clothing. Therefore, based on the areas responsible for each air outlet, the design of the micropores of the air outlets is different. In terms of the hole area, the micropores used in each air outlet are divided into two types: small holes and large holes. Among them, the air outlet areas responsible for the mainly uncovered parts of the human body adopt small hole designs to reduce the blowing feeling; the air outlet areas responsible for the mainly covered parts of the human body adopt large hole designs to enhance the cooling effect. Therefore, the first air outlet area and the third air outlet area of the rear air outlet adopt small holes, and the second air outlet area adopts large holes.

[0090] The air dispersion holes in the first air outlet area and the third air outlet area adopt small hole designs. By reducing the area of a single hole, the air flow impact speed is reduced, forming a gentle air flow to avoid the blowing feeling on the bare skin. The second air outlet area adopts large holes to increase the air flow penetration to penetrate the clothing fibers to enhance the cooling effect.

[0091] See Figure 3 and Figures 7 to 10 As shown, in some optional embodiments, the rear air outlet includes a rectangular parallelepiped-shaped rear air dispersion plate, and the first air outlet area 11, the second air outlet area 12, and the third air outlet area 13 are formed on the rear air dispersion plate; the rear air dispersion plate has a length direction X, a width direction Y, and a normal direction Z that are perpendicular to each other. The length direction X is adapted to point to the front of the vehicle, and the width direction Y is adapted to point to the side window; the normal direction of the rear air dispersion plate is adapted to form an installation angle α with the ground of the rear passenger space, and the angle value of the installation angle α is 65° - 70°;

[0092] The air dispersion holes in the first air outlet area 11 of the rear air outlet meet at least one of the following:

[0093] The outer rotation angle b 11 = α - 65°, and the outer rotation angle is the angle of the air dispersion hole rotating around the X-axis in the YZ plane, where a positive rotation angle towards the window side and a negative rotation angle towards the interior of the vehicle.

[0094] The outer rotation angle b 11 = α - 65°. When α = 65° - 70°, b 11 = 0° to +5°. A positive deflection means that the air flow is more towards the window side. The positive deflection makes the air flow flow towards the window side, preferentially cooling the heat source on the window side. After the air flow is reflected by the window, it forms a downward sink, naturally covering the feet, avoiding local overcooling caused by direct blowing, and the air flow reflection path improves the cooling uniformity.

[0095] The rear rotation angle c 11 satisfies 3° ≤ c 11≤7°, where the rear deflection angle is the angle of rotation around the Y-axis in the XZ plane, with rotation towards the rear of the vehicle being a positive angle and rotation towards the front of the vehicle being a negative angle. Positive deflection prolongs the residence time of airflow in the footwell, increasing heat exchange time.

[0096] It should be noted that the method for determining the local coordinate system in this application is also applicable to other air vents. Each air vent's diffuser plate has its own local coordinate system determined by having mutually perpendicular length direction X, width direction Y, and normal direction Z. The length direction X is adapted to point directly forward of the vehicle, and the width direction Y is adapted to point towards the side window. All diffusers are cuboid in shape, satisfying the condition that the length is greater than the width, the width is greater than the thickness, and the normal direction Z can be understood as the thickness direction. (See reference...) Figures 7 to 10 As shown, Figure 8 This is a schematic diagram of the outer corner of the air outlet. Figure 10 This is a schematic diagram of the corner behind the air outlet. Based on Figure 2 The local coordinate system of the air outlet shown shows that the outer rotation angle b is the angle of rotation of the micro-hole around the X-axis in the YZ plane, that is, the angle of deflection to the left and right in the passenger compartment. Rotation towards the window is a positive angle, and rotation towards the inside of the vehicle is a negative angle. The rear rotation angle c is the angle of rotation around the Y-axis in the XZ plane, that is, the angle of deflection forward and backward in the passenger compartment. Rotation towards the rear of the vehicle is a positive angle, and rotation towards the front of the vehicle is a negative angle.

[0097] In some alternative embodiments, the rear exhaust vent includes:

[0098] The first rear exhaust vent 4 is suitable for being arranged near the rear air conditioning unit, and the outer angle b of the air diffuser hole in the second air outlet area of ​​the first rear exhaust vent 4 is [missing information]. 121 =α-65°, back turn angle c 91 Satisfying 8°≤c 91 ≤12°;

[0099] The second rear exhaust vent 6 is suitable for being arranged on the side away from the rear air conditioning unit, and the outer corner b of the micro-holes in the second air outlet area of ​​the second rear exhaust vent 6 is [missing information]. 122 =b 121 -5°;

[0100] The rear corner c of the second air outlet zone of the second rear air outlet 6 122 The rear angle c of the second air outlet area of ​​the first rear air outlet 4 121 equal.

[0101] The second air outlet zones of the first rear air outlet 4 and the second rear air outlet 6 are responsible for cooling the occupant's neck, chest, abdomen, and arms away from the window. The first rear air outlet is located near the rear air conditioning unit. The airflow attenuation of the diffuser holes in the second air outlet zone of the first rear air outlet is small, and a positive outward angle (b) is used. 121= α - 65° ≈ 0° to +5°), where the outer rotation angle is the angle of the air dispersion holes rotating around the X-axis in the YZ plane, with a positive angle for rotation towards the window side and a negative angle for rotation towards the interior of the vehicle. The second rear air outlet 6 is adapted to be arranged on the side away from the rear air-conditioning box. The air flow attenuation of the air dispersion holes in the second air outlet area of the second rear air outlet is relatively large. The second air outlet (far end) compensates for the air flow attenuation by reducing the outer rotation angle by 5° (b 122 = b 121 - 5°), which can balance the wind speed on the upper bodies of the passengers on both sides of the rear passenger space. In other words, the air dispersion holes in the second air outlet area of the second rear air outlet are more directly directed towards the interior of the vehicle than the air dispersion holes in the second air outlet area of the first rear air outlet, thereby balancing the air flow attenuation caused by its distance from the rear air-conditioning box.

[0102] Rear rotation angle consistency, that is, maintaining c 121 = c 122 . The rear rotation angle is the angle of rotation of the XZ plane around the Y-axis, with a positive angle for rotation towards the rear of the vehicle and a negative angle for rotation towards the front of the vehicle. The rear rotation angle c 122 of the second air outlet area of the second rear air outlet 121 is equal to the rear rotation angle c

[0103] of the second air outlet area of the first rear air outlet, and it can also be 8° - 12° to avoid direct air blowing. 13 = 90° - α, and the rear rotation angle c 13 is 0°. The third air outlet area is responsible for the areas corresponding to the arms, calves, and thighs of the passengers near the window side. The 90° - α outer rotation angle scatters the air flow along the window direction, and the rear rotation angle c 13 being 0° can reduce the air flow attenuation, forming an air curtain along the window direction to isolate the high temperature on the window side and keep the areas of the arms, calves, and thighs of the passengers near the window side cool.
