Detailed Implementation
[0044] In the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only 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.
[0045] In the embodiments of the present application, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or 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 that element.
[0046] Refer Figures 1 to 4 As shown, an embodiment of the present invention discloses an air outlet assembly for a vehicle 100 having a rear seating space 110. The air outlet assembly includes a plurality of air outlet ends, and the plurality of air outlet ends include:
[0047] The first rear air outlet ends 205 / 206 / 209 / 210 are adapted to be arranged at the C-pillar of the vehicle 100 for supplying air to the rear seating space 110.
[0048] The plurality of air outlet ends of the air outlet assembly include the first rear air outlet ends 205 / 206 / 209 / 210, which are adapted to be arranged at the C-pillar of the vehicle 100. Thus, the cold air of the air conditioner is delivered to the C-pillar, and the lateral air supply from the C-pillar air outlet end covers the passenger limb area, effectively reducing the temperature difference between the upper and lower parts caused by traditional single-point air supply and avoiding the problem of direct air blowing in the related art, such as the air directly blowing on the knees. The lateral air flow from the C-pillar air outlet end helps to achieve full coverage of the rear space.
[0049] For example, the C-pillar air outlet usually adopts a lateral air supply mode. The cold air can flow downward along the window glass, specifically solving the problem of local overheating of the arms and thighs caused by direct sunlight, or blowing to the middle space of the rear row to meet the cooling needs of the heads, chests and abdomens of the rear passengers, thereby at least improving the problem of large differences in the perceived temperature in different areas of the rear row of the vehicle 100 in some scenarios and enhancing the occupant's perceived comfort.
[0050] The C-pillar has a relatively large area, allowing for the placement of a larger rear air outlet (205 / 206 / 209 / 210) at the C-pillar. This reduces airflow speed while maintaining cooling effectiveness and comfort. Furthermore, the C-pillar is relatively close to the rear passenger space (110mm). Since larger vehicles like MPVs typically have both front and rear air conditioning, placing the C-pillar closer to the rear air conditioning unit reduces wind resistance and further enhances cooling efficiency.
[0051] In addition, the C-pillar arrangement avoids encroaching on legroom and does not interfere with head movement.
[0052] In some alternative embodiments, the plurality of air outlets further include a second rear air outlet 207 / 208, adapted to be arranged on the roof corresponding to the rear passenger space 110;
[0053] The first rear air outlet 205 / 206 / 209 / 210 and the second rear air outlet 207 / 208 are used to supply air to the rear passenger space 110.
[0054] The roof vents deliver air vertically, allowing the cool air to naturally sink and cover the rear passengers. This directs the cool air towards the lower body of the rear passengers, cooling their feet, calves, and thighs, thus further improving the problem of large temperature differences in different areas of the rear seats and enhancing passenger comfort.
[0055] In some alternative embodiments, the plurality of air outlets include a plurality of first rear air outlets 205 / 206 / 209 / 210, wherein a portion of the first rear air outlets 205 / 206 are adapted to be arranged at the leading edge of the rear window so that the airflow flows into the rear passenger space 110 along the rear window, and a portion of the first rear air outlets 209 / 210 are adapted to blow the airflow toward the center of the rear passenger space 110.
[0056] Some of the first rear air outlets 205 / 206 are positioned at the front edge of the window so that cold air flows into the passenger compartment along the window, responsible for cooling the arms and other parts of the rear passengers near the window. Some of the first rear air outlets 209 / 210 are adapted to blow cold air towards the middle space of the rear seats to meet the cooling needs of the rear passengers' heads and chest and abdomen.
[0057] The air vents at the front edge of the windows form a "cool air curtain," specifically reducing localized high temperatures on the sides of the windows caused by direct sunlight. The central air vents directly cover the core torso area of the passengers, achieving rapid cooling of the head, chest, and abdomen. The airflow from the side windows naturally descends along the glass, avoiding the discomfort of direct airflow, while the central airflow can use an axial air delivery mode. These two airflows create a three-dimensional circulation in the passenger area, improving temperature uniformity.
[0058] In some alternative embodiments, the second rear air outlet 207 / 208 is adapted to be positioned on the roof at the front of the rear seating space 110 to blow cool air towards the lower body area of the rear passengers, responsible for cooling the feet, calves, and thighs of the rear passengers. For example, in a specific implementation, the second rear air outlet 207 / 208 is installed at a height controlled within the headliner layer at the front of the roof, and with a concealed air duct design, it ensures Z-axis headroom while avoiding interference with leg movement caused by traditional armrest rear air outlets.
[0059] For example, in some optional embodiments, the plurality of air outlets includes four first rear air outlets 205 / 206 / 209 / 210, two of which are arranged at the leading edge of the rear windows on both sides, and two of which are arranged at the roof position at the front of the rear passenger space 110. The air outlets arranged at the leading edge of the rear windows on both sides can form a "cool air curtain," with airflow naturally descending along the glass surface, specifically reducing the high-temperature radiation from direct sunlight on the window side, thus lowering the perceived temperature of the limbs near the window, while avoiding the discomfort of airflow blowing directly onto the passenger's face as in related technologies. The dual air outlets at the front of the roof adopt a vertical air delivery mode, with cool air naturally descending to cover the lower limb area, such as from the feet to the thighs, which can improve the problem of delayed cooling in the foot space in traditional layouts.
[0060] In some alternative embodiments, the vehicle 100 also has a middle row seating space 120, and the plurality of air vents further include:
[0061] The first middle row air outlet 203 / 204 / 211 / 212 is suitable for being arranged on the upper edge of the middle row window;
[0062] The second middle row air outlet 201 / 202 / 213 / 214 is adapted to be arranged on both sides of the roof corresponding to the middle row seating space 120;
[0063] The first middle exhaust air outlet 203 / 204 / 211 / 212 and the second middle exhaust air outlet 201 / 202 / 213 / 214 are used to supply air to the middle row seating space 120.
[0064] The first middle-row air outlets 203 / 204 / 211 / 212 are positioned along the upper edge of the window to allow cool air to flow along the window into the side areas of the middle row of the passenger compartment. For example, in summer, the arms and thighs of passengers near the window feel hotter than other parts of the body due to direct sunlight; cool air flowing from the upper edge of the window helps improve thermal comfort in these areas. The second middle-row air outlets 201 / 202 / 213 / 214 are suitable for being positioned on both sides of the roof corresponding to the middle-row seating space 120, directing airflow towards the middle area of the middle row of the passenger compartment, responsible for cooling the area from the passenger's head to their thighs. This can at least alleviate the problem of significant differences in perceived temperature between different areas of the middle row of the vehicle 100 in some scenarios, improving passenger comfort.
[0065] In some optional embodiments, the plurality of air outlets includes four first middle-row air outlets 203 / 204 / 211 / 212, adapted to be arranged on the upper edge of the middle-row windows on both sides of the vehicle 100; and four second middle-row air outlets 201 / 202 / 213 / 214, respectively arranged on both sides of the roof corresponding to the middle-row seating space 120. Thus, a total of eight middle-row air outlets can form symmetrical airflow. Two air outlets on each side form a continuous cool air curtain, covering the entire length of the middle-row windows, reducing the perceived temperature in the side window area, and effectively solving the "one-sided scorching" phenomenon caused by large side windows in MPV models. The four second middle-row air outlets 201 / 202 / 213 / 214 on both sides of the roof are responsible for cooling the head and chest area.
[0066] In some optional embodiments, the air outlet includes a diffuser plate 2011, which has a plurality of perforations extending along its thickness direction, so that air is dispersed by the perforations when passing through the diffuser plate 2011. The array of perforations forms a porous medium structure, causing turbulent mixing when airflow passes through, improving the uniformity of airflow and effectively eliminating localized strong wind zones.
[0067] For example, in some alternative embodiments, the ventilation area of the vent is 1.76 mm. 2 -3.15mm 2 When air passes through the diffuser 2011, it is dispersed into multiple gentle breezes by the micropores, thus reducing wind speed. The micropore area is controlled at 1.76mm. 2 -3.15mm 2 Within a certain range, if the micropore area is too small, it will increase the airflow resistance, thereby reducing the air volume and affecting the cooling effect. If the area is too large, the effect of reducing the wind speed will be insignificant, resulting in passengers feeling a strong draft and poor comfort.
[0068] In some optional embodiments, the cross-sectional shape of the vent along the thickness direction of the diffuser plate 2011 includes one or more of the following: circular, rectangular, polygonal, elliptical, and rhomboid. Here, a polygon can be understood as a pentagon or more complex shape. In specific implementations, the shape can be selected according to specific needs and the characteristics of the vent cross-sectional shape. For example, a circular cross-section is beneficial for forming axisymmetric airflow, reducing pressure loss, and is suitable for areas with high wind speed requirements. A rectangular cross-section allows for easy adjustment of the aspect ratio. A polygonal cross-section (non-rectangular) enhances turbulent mixing due to edge effects, which can improve temperature uniformity. This is merely an example; combinations can also be used in specific implementations.
[0069] In some optional embodiments, the air outlet end further includes a baffle 2012, which is disposed on the air outlet side of the diffuser plate 2011 and is used to divide the air outlet side of the diffuser plate 2011 into multiple air outlet zones to facilitate the formation of a static pressure chamber 307. For example, in a specific implementation, the baffle 2012 can divide the air outlet side of the diffuser plate 2011 into 4-6 air outlet zones. The opening ratio of each air outlet zone can be set individually according to requirements to balance airflow resistance, keep the static pressure difference between each air outlet zone at a low level, and improve the uniformity of airflow.
[0070] In some optional embodiments, the air outlet assembly further includes an air outlet 3 corresponding to the air outlet end. The air outlet 3 includes an air outlet housing 306, which surrounds the air outlet end and forms an air outlet chamber that extends through the air outlet end. For example, in a specific implementation, each air outlet end of the air duct is equipped with one air outlet 3, that is, the number of air outlet ends is equal to the number of air outlets 3. The baffle 2012 of the air outlet end separates the air outlet end, thereby forming multiple static pressure chambers 307 with the air outlets 3. The number of static pressure chambers 307 in a single air outlet area is 4-6, and the number of static pressure chambers 307 in the air outlet area can be adjusted according to the airflow uniformity affected by the structure of the vehicle 100.
[0071] In some alternative embodiments, the air outlet end further includes a partition 2012, which is disposed on the air outlet side of the diffuser plate 2011 and is used to divide the air outlet side of the diffuser plate 2011 into multiple air outlet zones.
[0072] The air outlet 3 also includes a plurality of first guide vanes 301, which are rotatably disposed in the air outlet chamber and correspond to the plurality of air outlet areas.
[0073] In practice, the deflector plates correspond one-to-one with the air outlet areas, and each deflector plate can rotate to adjust the air delivery angle.
[0074] In some alternative embodiments, the rotation axis of the first guide vane 301 is disposed adjacent to the corresponding partition 2012. This ensures that the static pressure chambers 307 remain separated from each other when the guide vane rotates, thereby maintaining pressure balance.
[0075] In some alternative embodiments, the air outlet 3 further includes a plurality of second guide vanes 302, which are rotatably disposed in the air outlet chamber and intersect the extending direction of the first guide vane 301.
[0076] For example, in a specific implementation, the first guide vane 301 can be a longitudinal guide vane, and the second guide vane 302 can be a transverse guide vane. The first guide vane 301 and the second guide vane 302 can form a 60°-90° intersection angle, which can decompose the airflow into horizontal and vertical components. For example, the longitudinal guide vane can adjust the horizontal sweep range of ±30°, and the transverse guide vane can control the pitch angle of ±15° to achieve three-dimensional air supply coverage.
[0077] In some optional embodiments, the plurality of first guide vanes 301 are linked together by a first connecting rod 303. The air outlet 3 also includes an adjusting member 304. When the adjusting member 304 adjusts at least one of the first guide vanes 301 to rotate, the other first guide vanes 301 are driven to rotate synchronously through the first connecting rod 303, so as to ensure the consistency of the actions of the plurality of first guide vanes 301.
[0078] Similarly, in some alternative embodiments, the plurality of second guide vanes 302 are linked together by a second connecting rod 305, and the adjusting member 304 is installed on one of the second guide vanes 302 to control the rotation of the second guide vane 302, and drives the other second guide vanes 302 to rotate synchronously through the second connecting rod 305.
[0079] In some alternative embodiments, the adjusting member 304 includes a control arm extending to the at least one first deflector 301, the adjusting member 304 adjusting the rotation of the at least one first deflector 301 via the control arm.
[0080] This application also discloses a vehicle air conditioner, including a rear air conditioning duct 2 and the aforementioned air outlet assembly; the plurality of air outlets are formed on the rear air conditioning duct 2.
[0081] In some alternative embodiments, the vehicle air conditioner also includes a rear air conditioning unit 1, which is adapted to be disposed at the rear end of the vehicle 100, and the rear air conditioning duct 2 is connected to the rear air conditioning unit 1.
[0082] This application also discloses a vehicle 100, including the aforementioned air outlet assembly, or including the aforementioned vehicle air conditioner.
[0083] In the aforementioned air vent assembly, vehicle air conditioner, and vehicle 100, the multiple air vents of the air vent assembly include a first rear air vent 205 / 206 / 209 / 210, suitable for placement at the C-pillar of the vehicle 100; and a second rear air vent 207 / 208, suitable for placement at the roof corresponding to the rear passenger space 110. In this way, the air conditioner delivers cool air to the C-pillar and roof, utilizing high-level airflow to allow the cool air to naturally sink and cover the rear passengers. The C-pillar air vents typically employ a side-flow mode, with cool air flowing downwards along the window glass, specifically addressing the problem of localized overheating of the arms and thighs caused by direct sunlight. The roof air vents provide vertical airflow, meeting the cooling needs of the rear passengers' heads, chests, and abdomens. This at least alleviates the problem of significant temperature differences in different areas of the rear seats of the vehicle 100 in some scenarios, improving passenger comfort. It is understood that the vehicle air conditioner and vehicle disclosed in this invention inherit all the improvements and advantages of the air outlet component, so they will not be discussed separately in detail here.
[0084] For ease of understanding, the following detailed exemplary embodiment will be used to describe the overall solution of this application, so as to explain some of the technical details of this application in a holistic manner. The additional technical details introduced therein do not constitute additional limitations on this application.
[0085] like Figures 1 to 4 As shown, the rear air conditioning unit 1 is located at the very rear of the vehicle (either the left or right side). The air vents of the rear air conditioning unit have dampers inside, allowing the airflow to be adjusted by controlling the damper opening. The rear air conditioning duct 2 is connected to the rear air conditioning unit 1 and is located inside the vehicle's roof; it can also be called the roof duct. The rear air conditioning outlet 3 is connected to the outlet end of the rear air conditioning duct. The rear air conditioning unit 1, the rear air conditioning duct 2, and the outlet 3 are responsible for supplying air to the middle and rear passenger compartments.
[0086] The rear air conditioning duct 2 contains 14 air outlets, namely 201-214 in the figure. 215 is the air inlet of the duct, which is connected to the air outlet 11 of the rear air conditioning unit to guide air into the duct.
[0087] Air outlets 201, 202, 213, and 214 direct airflow towards the middle area of the passenger compartment, responsible for cooling the area from the passenger's head to their thighs. Air outlets 203, 204, 211, and 212 are all located along the upper edge of the windows so that cool air flows along the windows into the side areas of the middle row of the passenger compartment. In summer, the arms and thighs of passengers near the windows feel hotter than other parts of the body due to direct sunlight; the cool air flowing out from the upper edge of the windows helps improve thermal comfort in these areas.
[0088] Air outlets 205-210 are responsible for supplying air to the rear passenger compartment. Air outlets 205, 206, 209 and 210 are placed at the middle row pillar (i.e., C pillar). Air outlets 206 and 209 are positioned at the front edge of the window so that cold air flows into the passenger compartment along the window, responsible for cooling the arms and other parts of the rear passengers near the window. Air outlets 205 and 210 blow cold air towards the middle space of the rear row to meet the cooling needs of the rear passengers' heads, chest and abdomen.
[0089] Air outlets 207 and 208 are located on the roof behind the middle row seats, blowing cool air towards the lower body area of the rear passengers, responsible for cooling the feet, calves and thighs of the rear passengers.
[0090] Each air outlet is equipped with a diffuser plate 2011 and a baffle plate 2012. The diffuser plate has micropores evenly distributed throughout. When air passes through the diffuser plate, it is dispersed into multiple gentle breezes by the micropores, thereby reducing wind speed. The micropore area is controlled at 1.76 mm². 2 -3.15mm 2 Within a certain range, if the micropore area is too small, it will increase the airflow resistance, thereby reducing the airflow and affecting the cooling effect. If the area is too large, the effect of reducing the airflow speed will be insignificant, resulting in a noticeable draft and poor comfort for passengers. The air outlet baffle 2012 separates the air outlet, thus forming multiple static pressure chambers with the air outlet 3. The number of static pressure chambers in a single air outlet area is 4-6. The number of static pressure chambers in the air outlet area can be adjusted according to the airflow uniformity affected by the vehicle structure.
[0091] The detailed structure of air outlet 3 is as follows Figure 4 As shown, each air outlet end of the air duct is equipped with an air outlet, that is, the number of air outlet ends is equal to the number of air outlets. Figure 4301 is a transverse guide vane, 302 is a longitudinal guide vane, 303 is a longitudinal guide vane connecting rod, 304 is an adjustment knob, 305 is a transverse guide vane connecting rod, 306 is the air outlet shell, 307 is a static pressure chamber, and 3021 is a longitudinal guide vane rotation shaft. Within each air outlet, there are multiple transverse guide vanes 301, configured as needed according to the air outlet geometry; the number of longitudinal guide vanes 302 is equal to the number of baffles 3012 connected to the air outlet end, and their positions correspond to each other. The longitudinal guide vanes 302, baffles 3012, and air outlet shell 306 form multiple static pressure chambers 307. After being dispersed into multiple streams of gentle air by the diffuser 2011, the air flows through the micropores into the static pressure chambers. Due to the sudden increase in flow area within the static pressure chambers compared to the micropores, the air velocity further decreases upon entering the static pressure chambers, and pressure equilibrium is achieved within the static pressure chambers before flowing into the passenger compartment via the transverse guide vanes 301. The longitudinal guide vane 302 can rotate left and right around its rotation axis 3021 via the horizontal and vertical adjustment knobs 304, while the lateral guide vane 301 can rotate up and down. The combined use of the longitudinal and lateral guide vanes 302 and 301 changes the direction of airflow from the static pressure chambers, allowing the direction of airflow into the passenger compartment to be adjusted according to passenger needs. The adjustment knob 304 is nested with a specific lateral guide vane 301 for control, and is linked to the other lateral guide vanes via the lateral guide vane linkage 305 for synchronized control. The adjustment knob 304 adjusts the rotation of a specific longitudinal guide vane 302 via a control arm extending into the air outlet, and is linked to the other longitudinal guide vanes via the longitudinal guide vane linkage 303 for synchronized control. The position of the longitudinal guide vane rotation axis 3021 should be close to the air duct outlet baffle 2012, ensuring that the static pressure chambers remain separated during the rotation of the longitudinal guide vane 302, thus maintaining pressure balance.
[0092] During the rapid cooling phase, the arrangement of multiple air vents ensures a sufficient total airflow while minimizing the airflow at each vent, thus reducing the feeling of drafts on passengers. This improves both cooling capacity and comfort during the rapid cooling phase. Once the interior temperature reaches the target value, the space-surrounding air vent arrangement, combined with the designed vents, prevents direct airflow onto the body while ensuring that passengers are covered by cool air at a low velocity (less than 0.3 m / s). Furthermore, the variable airflow direction of the vents caters to the needs of different groups. This patent improves the uniformity of temperature distribution across the body while also meeting the specific needs of different passengers for a comfortable airflow.
