Description

Technical Field

[0001] This application belongs to the field of vehicle technology, and more specifically, relates to an air conditioning duct and a vehicle. Background Technology

[0002] Large vehicles are typically equipped with two air conditioners. For example, vehicles with three rows of seats usually have a rear air conditioner, which is used for temperature control and air circulation in the middle and rear cabins of the vehicle.

[0003] Vehicles equipped with rear air conditioning typically have the air conditioning ducts installed in the roof, which increases the thickness of the roof and results in a smaller space in the passenger compartment height direction. Utility Model Content

[0004] The purpose of this application is to provide an air conditioning duct and a vehicle to solve the problem of small space size in the passenger cabin height direction, and to facilitate seat function upgrades.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] In a first aspect, an air conditioning duct is provided for installation on the body of a vehicle, the body including a side panel assembly and a floor assembly, the side panel assembly including a first side panel assembly and a second side panel assembly disposed opposite to each other along the width direction of the vehicle, the vehicle's air conditioner being installed on the first side panel assembly, the air conditioning duct including a face-blowing duct and a foot-blowing duct for connecting the air conditioner, at least one of the face-blowing duct and the foot-blowing duct being disposed on the side panel assembly and the floor assembly.

[0007] With the above technical solution, at least one of the face air duct and the foot air duct is located in the side panel assembly and the floor assembly. That is, at least one of the face air duct and the foot air duct is not located in the roof. At least one of the face air duct and the foot air duct will not increase the thickness of the roof, will not affect the structural layout of the roof, and will help reduce the space occupied by the roof. This will help increase the space dimension in the vehicle cabin in the direction of seating height, and will also help upgrade the seat function.

[0008] Therefore, the air conditioning duct provided in this application helps to solve the problem of small space dimensions in the height and width directions of the vehicle cabin, and also facilitates the upgrading of seat functions.

[0009] In some embodiments, the blowing air duct includes a first blowing air duct disposed in the first side assembly.

[0010] In this way, the first air duct can be located on the first side panel assembly, avoiding the need to increase the size of the vehicle roof, providing more room for roof design, and reducing the space occupied by the roof, thereby increasing the space in the vehicle's passenger compartment in the height direction. Furthermore, the first air duct can regulate the temperature and supply circulating air to the vehicle interior from the first side panel assembly, facilitating the air conditioning system to regulate the interior temperature and improving passenger comfort.

[0011] In some embodiments, the first side panel assembly includes a first C-pillar, and the air outlet of the first air duct is disposed on the first C-pillar.

[0012] In this way, the air outlet of the first air duct is located at the first C-pillar, which makes it easy to adjust the airflow direction of the first air duct outlet to regulate the temperature and deliver circulating air to the seats at different positions in the front and rear directions of the vehicle, thereby improving the comfort of passengers inside the vehicle.

[0013] In some embodiments, the face blowing duct further includes a second face blowing duct for connecting an air conditioner, the second face blowing duct being at least partially disposed in the second side assembly and the floor assembly.

[0014] In this way, the second air duct can be installed on the second side panel assembly and the floor assembly, avoiding the need to increase the size of the vehicle roof. This allows for more design flexibility for the roof and reduces the space occupied by the roof, thereby increasing the space in the vehicle's passenger compartment in the height direction. Furthermore, the second air duct can regulate the temperature and supply circulating air to the vehicle interior from the second side panel assembly, facilitating the air conditioning system to regulate the interior temperature and improving passenger comfort.

[0015] In some embodiments, the second side assembly includes a second C-pillar, and the air outlet of the second air duct is disposed on the second C-pillar.

[0016] In this way, the air outlet of the second air duct is located at the second C-pillar, which makes it easy to adjust the airflow direction of the second air duct outlet to regulate the temperature and deliver circulating air to the seats at different positions in the front and rear directions of the vehicle, thereby improving the comfort of passengers inside the vehicle.

[0017] In some embodiments, the second air duct includes a first pipe, a second pipe, and a third pipe connected in sequence. The first pipe is used to connect to an air conditioner, the second pipe is disposed in the floor assembly, the third pipe is disposed in the second side panel assembly, and the air outlet of the second air duct is disposed in the third pipe.

[0018] In this way, by placing the second air duct in the floor assembly, the air conditioner on the first side panel assembly can blow air through the first and second ducts to the third duct in the second side panel assembly. This avoids increasing the size of the vehicle roof, provides more room for roof design, and also helps to reduce the space occupied by the roof, thereby increasing the space in the vehicle cabin in the direction of passenger height.

[0019] In some implementations, the second blowing air duct satisfies at least one of the following conditions:

[0020] The first pipe includes a first end and a second end. The first end is connected to an air conditioner, and the second end is connected to a second pipe. The length of the short side of at least a portion of the cross-section of the first pipe gradually decreases along the direction from the first end to the second end. The cross-section of the first pipe is perpendicular to the extension direction of the first pipe.

[0021] The second and third pipes are set at an angle, and the angle formed by the second and third pipes is an obtuse angle;

[0022] The vehicle includes a third row of seats, with the second pipe located behind the third row of seats;

[0023] The ratio of the short side length to the long side length of the cross-section of the second pipe is less than or equal to 0.5. The thickness direction of the second pipe is consistent with the front-rear direction of the vehicle. The cross-section of the second pipe is perpendicular to the extension direction of the second pipe.

[0024] In this way, the first pipe can serve as a transition pipe, allowing the air blown out by the air conditioner to enter the second pipe, which has a shorter shorter side in its cross-sectional thickness, and also helps to increase the air velocity in the second pipe.

[0025] In addition, the angle formed by the second and third pipes is an obtuse angle, which can reduce the resistance when air enters the third pipe from the second pipe, making it easier for air to enter the third pipe from the second pipe.

[0026] In addition, the second pipe is located behind the third row of seats, which can reduce the space occupied between the third row of seats and the floor assembly, making it easier to install the third row of seats and upgrade the seat functions.

[0027] Furthermore, the ratio of the shorter side length to the longer side length of the second pipe's cross-section is less than or equal to 0.5, the length direction of the shorter side of the second pipe's cross-section is consistent with the vehicle's longitudinal direction, and the cross-section of the second pipe is perpendicular to its extension direction. This helps to reduce the size of the second pipe in the vehicle's longitudinal direction, thereby reducing the space occupied by the second pipe in that direction and facilitating the adjustment of the third-row seats in different positions.

[0028] In some embodiments, the air conditioning duct also includes a foot-blowing duct for connecting the air conditioner, at least a portion of which is a flat pipe, the ratio of the short side length to the long side length of the cross section of the flat pipe being less than or equal to 0.5, and the cross section of the flat pipe being perpendicular to the extension direction of the flat pipe.

[0029] In this way, the foot-blowing air duct can reduce the space occupied in the short side length direction of the cross-section of the flat pipe, which facilitates the interior space layout of the vehicle.

[0030] In some embodiments, the foot-blowing duct includes a fourth duct and a fifth duct. The fourth duct is connected to an air conditioner, and the fifth duct is connected to the fourth duct. The fourth duct is disposed in the first side panel assembly, and the length direction of the shorter side of the cross-section of the fourth duct is aligned with the thickness direction of the first side panel assembly. The cross-section of the fourth duct is perpendicular to its extension direction. The fifth duct is disposed in the floor assembly, and the length direction of the shorter side of the cross-section of the fifth duct is aligned with the height direction of the floor assembly. The cross-section of the fifth duct is perpendicular to its extension direction. The foot-blowing duct satisfies at least one of the following conditions:

[0031] The ratio of the shorter side length to the longer side length of the cross-section of the fourth pipe is less than or equal to 0.5;

[0032] The ratio of the shorter side length to the longer side length of the fifth pipe's cross-section is less than or equal to 0.5;

[0033] The fourth pipe includes a third end and a fourth end. The third end is connected to the air conditioner, and the fourth end is connected to the fifth pipe. The length of the short side of at least part of the cross-section of the fourth pipe gradually decreases along the direction from the third end to the fourth end.

[0034] The shorter side of the cross-section of the fourth pipe is longer than the shorter side of the cross-section of the fifth pipe;

[0035] The vehicle includes a third row of seats, with a fifth pipe located beneath the third row of seats.

[0036] In this way, the fourth pipe can reduce the space occupied in the short side length direction of the cross section, which is conducive to increasing the left and right interior space of the vehicle cabin in the thickness direction of the first side assembly, thereby helping to optimize the interior design and layout.

[0037] In addition, the fifth pipe can reduce the space occupied in the short side length direction of the cross section, which is conducive to increasing the interior space of the vehicle cabin in the height direction of the floor assembly, thereby helping to optimize the interior design and layout.

[0038] In addition, the short side length of at least part of the cross section of the fourth pipe gradually decreases in the direction from the third end to the fourth end. The fourth pipe can serve as a transition pipe, allowing the air blown out by the air conditioner to enter the fifth pipe with a smaller short side length.

[0039] In addition, the shorter side of the cross-section of the fourth pipe is longer than that of the fifth pipe, so the air blown out by the air conditioner can increase the air velocity in the fifth pipe after entering the fifth pipe from the fourth pipe.

[0040] In addition, the fifth duct is located under the third row of seats, which allows the fifth duct to blow air towards the passengers' feet.

[0041] In some embodiments, the floor assembly includes a middle floor, a rear floor, and a connecting plate, the connecting plate connecting the middle floor and the rear floor, and the air outlet of the foot blowing duct is located on the connecting plate.

[0042] In this way, the air outlet of the foot-blowing duct is located on the connecting plate, which makes it easy to blow air to the passengers' feet without increasing the size of the rear floor and the middle floor, and makes it easier to increase the space size of the vehicle cabin in the direction of passenger height.

[0058] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0060] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0061] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0062] Embodiments of this application provide a vehicle that can be a pure electric vehicle, or it can be any other battery-powered vehicle, such as a hybrid vehicle. Alternatively, the vehicle can be a gasoline-powered vehicle or a vehicle powered by other sources, such as a hydrogen fuel cell vehicle.

[0063] The vehicle provided in this application embodiment includes a vehicle body, on which an air conditioner and an air conditioning duct adjacent to the air conditioner can be installed. The air conditioning duct can be connected to the air outlet of the air conditioner, so that the air conditioner blows the heat-exchanged air into the air conditioning duct and then blows it into the vehicle interior through the air outlet of the air conditioning duct, thereby regulating the temperature inside the vehicle and supplying circulating air.

[0064] Large vehicles are typically equipped with two air conditioners. For example, vehicles with three rows of seats usually have a rear air conditioner, which is used for temperature control and air circulation in the middle and rear cabins of the vehicle.

[0065] Rear air conditioning systems typically have their ducts installed in the vehicle's roof, which increases the roof's thickness and results in a smaller vertical dimension for the vehicle.

[0066] To address the aforementioned technical problems, embodiments of this application provide an air conditioning duct and a vehicle.

[0067] Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The air conditioning duct 100 and the vehicle provided in the embodiments of this application will now be described.

[0068] The air conditioning duct 100 provided in this application embodiment is used for installation on the vehicle body 1000. The vehicle body 1000 includes a side panel assembly and a floor assembly 200. The side panel assembly includes components along the width direction of the vehicle (e.g., ...). Figure 1 A first side panel assembly 300 and a second side panel assembly 400 are arranged opposite each other (in the opposite direction of the Y-axis). The vehicle's air conditioner 500 is installed in the first side panel assembly 300. The first side panel assembly 300 can be a right side panel assembly, and the second side panel assembly 400 can be a left side panel assembly. It should be noted that in this embodiment, "left" and "right" are used with reference to the passenger's position facing the front of the vehicle.

[0069] It is understood that a vehicle may include a front air conditioner and a rear air conditioner. In this embodiment, the air conditioner 500 can be either a front air conditioner or a rear air conditioner. The following description uses the example of the air conditioner 500 being a rear air conditioner in this embodiment.

[0070] The air conditioning duct 100 provided in this embodiment includes a face-blowing duct and a foot-blowing duct 30 for connecting an air conditioner 500. At least one of the face-blowing duct and the foot-blowing duct 30 is disposed in the side panel assembly and the floor assembly 200. The air conditioner 500 may include multiple interfaces for connecting the ducts, and different interfaces can be connected to different ducts. The air conditioner 500 can blow air into the ducts through the interfaces. For example, the air conditioner 500 includes a first interface, a second interface, and a third interface.

[0071] Through the above technical solution, at least one of the face-blowing air duct and the foot-blowing air duct 30 is disposed in the side panel assembly and the floor assembly 200, that is, at least one of the face-blowing air duct and the foot-blowing air duct 30 is not arranged in the ceiling 700. For example, the face-blowing air duct is disposed in the side panel assembly and the floor assembly 200. For example, the foot-blowing air duct 30 is disposed in the side panel assembly and the floor assembly 200. For example, both the face-blowing air duct and the foot-blowing air duct 30 are disposed in the side panel assembly and the floor assembly 200.

[0072] It is understandable that at least one of the face-blowing air duct and foot-blowing air duct 30 will not increase the thickness of the roof 700, will not affect the structural layout of the roof 700, and is conducive to reducing the space occupied by the roof 700, thereby facilitating an increase in the vehicle's cabin seating height (e.g., Figure 1 The spatial dimensions in the Z direction.

[0073] Therefore, the air conditioning duct 100 provided in this application embodiment helps to solve the problem of small space size in the vehicle cabin seating height direction.

[0074] Please refer to the following: Figure 1 and Figure 2 In some embodiments, the blowing air duct includes a first blowing air duct 10, which is disposed on the first side assembly 300. The first blowing air duct 10 may be a right-side blowing air duct.

[0075] In this way, the first air duct 10 can be installed on the first side panel assembly 300, which avoids increasing the size of the vehicle roof 700, provides more room for the design of the roof 700, and also helps to reduce the space occupied by the roof 700, thereby increasing the space size of the vehicle cabin in the direction of passenger height. In addition, the first air duct 10 can regulate the temperature and supply circulating air to the interior of the vehicle from the first side panel assembly 300, which facilitates the air conditioning 500 to regulate the temperature inside the vehicle and helps to improve the comfort of passengers inside the vehicle.

[0076] Optionally, the first side assembly 300 includes a first C-pillar 301, and the air outlet of the first air duct 10 is disposed on the first C-pillar 301.

[0077] Among them, the first C-pillar 301 can be the right C-pillar, and the air outlet of the first blowing air duct 10 can be the first air outlet 11.

[0078] For example, the first air outlet 11 of the first air blowing duct 10 can be located at the upper end of the first C-pillar 301.

[0079] In this way, the air outlet of the first air duct 10 is located at the first C-pillar 301, which makes it easy to adjust the airflow direction of the air outlet of the first air duct 10 to regulate the temperature and deliver circulating air to the seats at different positions in the front and rear directions of the vehicle, thereby improving the comfort of passengers inside the vehicle.

[0080] It is understood that the vehicle provided in this application embodiment may include a first row of seats (not shown in the figure), a second row of seats (not shown in the figure), and a third row of seats 600 arranged sequentially from the front of the vehicle to the rear. The C-pillar is usually located between the second row of seats and the third row of seats 600. The first air outlet 11 of the first air blowing duct 10 is located at the first C-pillar 301, so that the first air outlet 11 can regulate the temperature and supply circulating air to the third row of seats 600, and can also regulate the temperature and supply circulating air to the first row of seats and the second row of seats.

[0081] For example, when there are no passengers in the third row of seats 600, the first air vent 11 can be directed toward the first row of seats and the second row of seats to regulate the temperature and deliver circulating air.

[0082] Optionally, the first side panel assembly 300 may further include a first D-pillar 302, which may be a right D-pillar, and the air conditioner 500 may be located between the first C-pillar 301 and the first D-pillar 302. The first side panel assembly 300 also includes a first wheel arch assembly 303, which may be a right wheel arch assembly. A first air duct 10 may be connected to a first interface of the air conditioner 500, which is located between the first C-pillar 301 and the first D-pillar 302, and close to the first D-pillar 302. The first air duct 10 extends from the first interface to the front of the first D-pillar 302, and then passes through the first wheel arch assembly 303 to reach the first C-pillar 301.

[0083] Optionally, the first air outlet 11 of the first air blowing duct 10 can also be set in other locations such as the ceiling 700, the first D-column 302, etc.

[0084] It should be noted that when the first air outlet 11 of the first air blowing duct 10 is set in the ceiling 700, the main structure of the first air blowing duct 10 is not arranged in the ceiling 700, only the first air outlet 11 is set in the ceiling 700. This has little impact on the size of the ceiling 700 and can be ignored.

[0085] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the air duct further includes a second air duct 20 for connecting the air conditioner 500, and at least a portion of the second air duct 20 is disposed on the second side assembly 400 and the floor assembly 200. The second air duct 20 may be a left-side air duct.

[0086] In this way, the second air duct 20 can be installed on the second side assembly 400 and the floor assembly 200, avoiding the need to increase the size of the vehicle roof 700. This allows for more design flexibility for the roof 700 and reduces the space occupied by it, thereby increasing the space in the vehicle cabin's height direction. Furthermore, the second air duct 20 can regulate the temperature and circulate air inside the vehicle from the second side assembly 400, facilitating the air conditioning 500 to adjust the interior temperature and improving passenger comfort.

[0087] Optionally, the second side assembly 400 includes a second C-pillar 401, and the air outlet of the second air duct 20 is disposed on the second C-pillar 401.

[0088] Among them, the second C-pillar 401 can be the left C-pillar, and the air outlet of the second blowing air duct 20 can be the second air outlet 24.

[0089] For example, the second air outlet 24 of the second air blowing duct 20 can be located at the upper end of the second C-pillar 401.

[0090] In this way, the air outlet of the second air duct 20 is located at the second C-pillar 401, which makes it easy to adjust the airflow direction of the air outlet of the second air duct 20 to regulate the temperature and deliver circulating air to the seats at different positions in the front and rear directions of the vehicle, thereby improving the comfort of passengers inside the vehicle.

[0091] For example, the second C-pillar 401 is located between the second-row seats and the third-row seats 600. The second air outlet 24 of the second air duct 20 is located at the second C-pillar 401, so that the second air outlet 24 can regulate the temperature and supply circulating air to the third-row seats 600, and can also regulate the temperature and supply circulating air to the first-row seats and the second-row seats.

[0092] For example, when the third row of seats 600 is not occupied, the second air vent 24 can be directed toward the first and second row of seats to regulate the temperature and deliver circulating air.

[0093] Please continue reading. Figure 2 and Figure 3 In some embodiments, the second air blowing duct 20 includes a first pipe 21, a second pipe 22 and a third pipe 23 connected in sequence. The first pipe 21 is used to connect to the air conditioner 500, the second pipe 22 is disposed on the floor assembly 200, the third pipe 23 is disposed on the second side assembly 400, and the air outlet of the second air blowing duct 20 is disposed on the third pipe 23.

[0094] Understandably, the first pipe 21 of the second air duct 20 is used to connect the air conditioner 500 installed on the first side panel assembly 300, while the third pipe 23 where the air outlet of the second air duct 20 is located is installed on the second side panel assembly 400. The second pipe 22 can cross the interior space of the vehicle and connect the first pipe 21 and the third pipe 23.

[0095] The second pipe 22 is located in the floor assembly 200, rather than in the roof 700 of the vehicle, which avoids increasing the size of the roof 700 and helps to reduce the space occupied by the roof 700.

[0096] In this way, by setting the second air duct 20 to the floor assembly 200, the air conditioner 500 on the first side assembly 300 can blow air through the first duct 21 and the second duct 22 to the third duct 23 set to the second side assembly 400. This avoids increasing the size of the vehicle roof 700, provides more room for the design of the roof 700, and also helps to reduce the space occupied by the roof 700, thereby helping to increase the space size of the vehicle cabin in the direction of passenger height.

[0097] Please refer to the following: Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments, the second blowing air duct 20 satisfies at least one of the following conditions:

[0098] The first pipe 21 includes a first end and a second end. The first end is connected to the air conditioner 500, and the second end is connected to the second pipe 22. The length of the short side of at least a portion of the cross-section of the first pipe 21 gradually decreases along the direction from the first end to the second end. The cross-section of the first pipe 21 is perpendicular to the extension direction of the first pipe 21.

[0099] The second pipe 22 and the third pipe 23 are arranged at an angle, and the angle formed by the second pipe 22 and the third pipe 23 is an obtuse angle;

[0100] The vehicle includes a third row of seats 600, and a second pipe 22 is located behind the third row of seats 600;

[0101] The ratio of the short side length to the long side length of the cross section of the second pipe 22 is less than or equal to 0.5. The length direction of the short side of the cross section of the second pipe 22 is consistent with the front-rear direction of the vehicle. The cross section of the second pipe 22 is perpendicular to the extension direction of the second pipe 22.

[0102] Optionally, the ratio of the short side length to the long side length of the cross section of the second pipe 22 can be K1, where the value of K1 can be: 0 < K1 ≤ 0.1, or 0.1 < K1 ≤ 0.2, or 0.2 < K1 ≤ 0.3, or 0.3 < K1 ≤ 0.4, or 0.4 < K1 ≤ 0.5.

[0103] For example, please refer to Figure 4 The first pipe 21 includes a first end and a second end. The first end is connected to the air conditioner 500, and the second end is connected to the second pipe 22. The shorter side length of at least a portion of the cross-section of the first pipe 21 gradually decreases along the direction from the first end to the second end. In this way, the first pipe 21 can serve as a transition pipe, allowing the air blown out by the air conditioner 500 to enter the second pipe 22, which has a shorter cross-section, and also helps to increase the airflow velocity in the second pipe 22.

[0104] For example, please refer to Figure 5 The second pipe 22 and the third pipe 23 are set at an angle, and the angle α formed by the second pipe 22 and the third pipe 23 is an obtuse angle. The obtuse angle α formed by the second pipe 22 and the third pipe 23 can reduce the resistance when air enters the third pipe 23 from the second pipe 22, making it easier for air to enter the third pipe 23 and increasing the smoothness of airflow.

[0105] It is understandable that the range of the included angle α formed by the second pipe 22 and the third pipe 23 can be: 100°≤α≤120°.

[0106] Optionally, the range of values ​​for α can be: 100°≤α≤105°, or 105°≤α≤110°, or 110°≤α≤115°, or 115°≤α≤120°.

[0107] For example, the value of α can be: 100°, 102.5°, 105°, 107.5°, 110°, 112.5°, 115°, 117.5°, 120°, etc.

[0108] For example, the second conduit 22 is located behind the third-row seat 600, which can reduce the space occupied between the third-row seat 600 and the floor assembly 200, facilitating the installation of the third-row seat 600 and seat function upgrades. For example, seat function upgrades can be to set the third-row seat 600 as a sliding seat.

[0109] For example, the ratio of the shorter side length to the longer side length of the cross-section of the second pipe 22 is less than 0.5, and the length of the shorter side of the cross-section of the second pipe 22 is proportional to the longitudinal direction of the vehicle (e.g., in the direction of travel). Figure 1 The X direction is consistent with that in the vehicle. This helps to reduce the size of the second pipe 22 in the front-rear direction of the vehicle, and can reduce the space occupied by the second pipe 22 in the front-rear direction of the vehicle, making it easier to adjust the third row seat 600 in different positions.

[0110] Optionally, the second side panel assembly 400 may further include a second D-pillar 402, which may be a left D-pillar. The first side panel assembly 300 also includes a second wheel arch assembly 403 and a first sound insulation cotton 405. The second wheel arch assembly 403 may be a left wheel arch assembly, and the first sound insulation cotton 405 may be laid on the second wheel arch assembly 403 for sound insulation and vibration reduction, thereby preventing abnormal noises.

[0111] It is understood that the first side assembly 300 may also include a first C ring 304 (right C ring) and a first D ring 305 (right D ring). The first C ring 304 may correspond to the position of the first C pillar 301, and the first D ring 305 may be located between the first C pillar 301 and the first D pillar 302.

[0112] Similarly, the second side assembly 400 may also include a second C ring (left C ring) and a second D ring 404 (left D ring), the second C ring may correspond to the position of the second C pillar 401, and the second D ring 404 may be located between the second C pillar 401 and the second D pillar 402.

[0113] The first duct 21 of the second air duct 20 can be connected to the second interface of the air conditioner 500. The second duct 22 is located in the floor assembly 200 and passes through the interior space from behind the third row of seats 600 to connect with the third duct 23. The third duct 23 bypasses the second D-ring 404, passes through the second wheel arch assembly 403, and then reaches the second C-pillar 401. The third duct 23 can be installed on the first sound insulation cotton 405 to reduce the vibration and noise of the third duct 23.

[0114] Optionally, the second air outlet 24 of the second air blowing duct 20 can also be set in other locations such as the ceiling 700, the second D column 402, etc.

[0115] It should be noted that when the second air outlet 24 of the second air blowing duct 20 is set in the ceiling 700, the main structure of the second air blowing duct 20 is not arranged in the ceiling 700, only the second air outlet 24 is set in the ceiling 700. This has little impact on the size of the ceiling 700 and can be ignored.

[0116] In this embodiment, the second pipe 22 is located behind the third-row seat 600, which reduces the space occupied under the third-row seat 600 and facilitates the installation of the third-row seat 600 and the upgrading of seat functions. For example, in this embodiment, the third-row seat 600 has a large installation space, and a sliding mechanism can be installed under the third-row seat 600 to allow the third-row seat 600 to slide along the front-rear direction of the vehicle, thereby improving passenger comfort.

[0117] It is understood that the third pipe 23 can also be a flat pipe. The length direction of the short side of the cross section of the third pipe 23 is the width direction of the vehicle body 1000. The air conditioning duct 100 of this application embodiment can reduce the length of the short side of the cross section of the third pipe 23 (the dimension in the vehicle width direction) and increase the length of the long side of the cross section of the third pipe 23 (the dimension in the vehicle height direction). The cross section of the third pipe 23 is perpendicular to the extension direction of the third pipe 23.

[0118] In this way, the third duct 23 can increase the interior space of the vehicle cabin in the width direction, which is beneficial to increasing the space of the luggage compartment in the width direction, and can also increase the shoulder, elbow and hip space of passengers in the third row of seats 600. Furthermore, by increasing the length of the long side of the cross-section of the third duct 23, the cross-sectional area of ​​the third duct 23 can remain unchanged or increase while the length of the short side of the cross-section decreases, which can give the second air blowing duct 20 good thermal performance.

[0119] Furthermore, the thickness of the first sound insulation cotton 405, where the third duct 23 is located, can also be reduced, which helps to increase the interior space of the vehicle cabin in the width direction. However, the thickness of the sound insulation cotton in other areas needs to be increased to compensate for the acoustic sacrifice caused by the reduced thickness of the first sound insulation cotton 405, so that the vehicle has good NVH performance.

[0120] For example, the length of the shorter side of the cross-section of the third pipe 23 can be greater than or equal to 25 mm. For example, the length of the shorter side of the cross-section of the third pipe 23 can be 25 mm, 27.5 mm, 30 mm, 32.5 mm, 35 mm, etc. The area of ​​the cross-section of the third pipe 23 can be greater than or equal to 4000 square centimeters. For example, the area of ​​the cross-section of the third pipe 23 can be 4000 square centimeters, 4100 square centimeters, 4200 square centimeters, 4300 square centimeters, 4400 square centimeters, 4500 square centimeters, etc.

[0121] Understandably, an acoustic package is a combination of acoustic materials and structures used in the automotive field to reduce noise propagation. Its main functions include sound absorption, sound insulation, damping, and vibration reduction. NVH performance refers to the comprehensive performance of noise, vibration, and harshness.

[0122] Please refer to the following: Figure 2 , Figure 3 and Figure 6 In some embodiments, at least a portion of the foot-blowing duct 30 is a flat pipe, the ratio of the shorter side length to the longer side length of the cross-section of the flat pipe is less than or equal to 0.5, and the cross-section of the flat pipe is perpendicular to the extension direction of the flat pipe. The foot-blowing duct 30 is disposed in the side panel assembly and the floor assembly 200.

[0123] In this way, the foot-blowing air duct 30 can reduce the space occupied in the short side length direction of the cross section by reducing the short side length of the cross section, which facilitates the interior space layout of the vehicle.

[0124] It is understandable that the ratio of the short side length to the long side length of the cross-section of a flat pipe can be K2, where the value of K2 can be: 0 < K2 ≤ 0.1, or 0.1 < K2 ≤ 0.2, or 0.2 < K2 ≤ 0.3, or 0.3 < K2 ≤ 0.4, or 0.4 < K2 ≤ 0.5.

[0125] Optionally, the foot-blowing duct 30 includes a fourth pipe 31 and a fifth pipe 32. The fourth pipe 31 is used to connect to the air conditioner 500, and the fifth pipe 32 is connected to the fourth pipe 31. The fourth pipe 31 is disposed in the first side panel assembly 300, and the length direction of the shorter side of the cross-section of the fourth pipe 31 is parallel to the thickness direction of the first side panel assembly 300 (e.g., the length direction of the shorter side of the cross-section of the fourth pipe 31 is parallel to the thickness direction of the first side panel assembly 300). Figure 2 The Y-direction of the fourth pipe 31 is consistent with the extension direction of the fourth pipe 31. The fifth pipe 32 is disposed on the floor assembly 200, and the length direction of the short side of the cross-section of the fifth pipe 32 is consistent with the height direction of the floor assembly 200 (e.g., the Y-direction). Figure 2 The Z-direction of the fifth pipe 32 is consistent with the extension direction of the fifth pipe 32, and the foot blowing duct 30 satisfies at least one of the following conditions:

[0126] The ratio of the shorter side length to the longer side length of the cross-section of the fourth pipe 31 is less than or equal to 0.5;

[0127] The ratio of the shorter side length to the longer side length of the cross-section of the fifth pipe 32 is less than or equal to 0.5;

[0128] The fourth pipe 31 includes a third end and a fourth end. The third end is connected to the air conditioner 500, and the fourth end is connected to the fifth pipe 32. The length of the short side of at least part of the cross-section of the fourth pipe 31 gradually decreases along the direction from the third end to the fourth end.

[0129] The shorter side length of the cross-section of the fourth pipe 31 is greater than the shorter side length of the cross-section of the fifth pipe 32;

[0130] The vehicle includes a third row of seats 600, and a fifth pipe 32 is located below the third row of seats 600.

[0131] For example, the ratio of the shorter side length to the longer side length of the cross-section of the fourth pipe 31 is less than or equal to 0.5. This ratio can be K3, where K3 can take values ​​of: 0 < K3 ≤ 0.1, 0.1 < K3 ≤ 0.2, 0.2 < K3 ≤ 0.3, 0.3 < K3 ≤ 0.4, or 0.4 < K3 ≤ 0.5. This reduces the space occupied by the fourth pipe 31 in the thickness direction, which helps increase the interior passenger space in the vehicle cabin in the thickness direction of the first side assembly 300, thus optimizing the interior design and layout. Furthermore, the fourth pipe 31 reduces the space occupied in the width direction of the vehicle, thereby increasing the space in the width direction of the vehicle cabin, which helps increase the space in the luggage compartment in the width direction, and also increases the shoulder, elbow, and hip space for passengers in the third-row seats 600.

[0132] Understandably, for example, the shorter side length of the cross-section of the fourth pipe 31 can be greater than or equal to 25 mm. For example, the shorter side length of the cross-section of the fourth pipe 31 can be 25 mm, 27.5 mm, 30 mm, 32.5 mm, 35 mm, etc. The area of ​​the cross-section of the fourth pipe 31 can be greater than or equal to 5500 square centimeters. For example, the area of ​​the cross-section of the fourth pipe 31 can be 5500 square centimeters, 5600 square centimeters, 5700 square centimeters, 5800 square centimeters, 5900 square centimeters, 6000 square centimeters, 6100 square centimeters, 6200 square centimeters, 6300 square centimeters, 6400 square centimeters, 6500 square centimeters, etc.

[0133] For example, the ratio of the shorter side length to the longer side length of the cross-section of the fifth conduit 32 is less than 0.5. This reduces the space occupied by the fifth conduit 32 in the direction of the shorter side length of its cross-section, which helps to increase the interior passenger space in the height direction of the floor assembly 200, thereby optimizing the interior design and layout. Specifically, the reduced space occupied by the fifth conduit 32 in the vehicle height direction facilitates the installation of the third-row seats 600 and upgrades to seat functions. For instance, the third-row seats 600 have ample installation space, and a sliding mechanism can be installed under the third-row seats 600 to allow them to slide along the fore-and-aft direction of the vehicle, improving passenger comfort.

[0134] Furthermore, the fifth conduit 32 can reduce its space occupation in the vehicle height direction by reducing the length of the shorter side of its cross-section, and it also facilitates the adjustment of the third-row seat 600. For example, the third-row seat 600 may include a seat cushion and a backrest, and the backrest can rotate around the seat pivot, making it easy for passengers to adjust their sitting posture and improving riding comfort.

[0135] The shorter side of the cross-section of the fifth pipe 32 can be greater than or equal to 25mm. For example, the shorter side of the cross-section of the fifth pipe 32 can be 25mm, 27.5mm, 30mm, 32.5mm, 35mm, etc.

[0136] For example, the fourth pipe 31 includes a third end and a fourth end. The third end is connected to the air conditioner 500, and the fourth end is connected to the fifth pipe 32. The shorter side length of at least a portion of the cross-section of the fourth pipe 31 gradually decreases along the direction from the third end to the fourth end. In this way, the fourth pipe 31 can serve as a transition pipe, allowing the air blown out by the air conditioner 500 to smoothly enter the fifth pipe 32, which has a shorter shorter side length, thus improving airflow smoothness and improving thermal performance.

[0137] For example, the shorter side of the cross-section of the fourth pipe 31 is longer than the shorter side of the cross-section of the fifth pipe 32. In this way, when the air blown out by the air conditioner 500 enters the fifth pipe 32 from the fourth pipe 31, the air velocity in the fifth pipe 32 can be increased, which is beneficial to improving the thermal performance indicators.

[0138] For example, the fifth conduit 32 is located below the third row of seats 600 to facilitate airflow to the passengers' feet.

[0139] Please refer to the following: Figure 2 and Figure 6 In some embodiments, the floor assembly 200 includes a middle floor 203, a rear floor 201, and a connecting plate 202. The connecting plate 202 connects the middle floor 203 and the rear floor 201, and the air outlet of the foot blowing duct 30 is disposed on the connecting plate 202.

[0140] In this way, the air outlet of the foot-blowing duct 30 is located on the connecting plate 202, which makes it easy to blow air to the passenger's feet without increasing the size of the rear floor 201 and the middle floor 203, thus facilitating the increase of the space size in the height direction of the vehicle.

[0141] It is understandable that the air outlet of the foot-blowing duct 30 can be a third air outlet 33. The third air outlet 33 can also be located on the first C-ring 304 of the first side panel assembly 300 or the first wheel arch assembly 303. Optionally, the third air outlet 33 can also be located on the second C-ring of the second side panel assembly 400 or the second wheel arch assembly 403. Of course, the third air outlet 33 can also be located in other positions where air can blow towards the passenger's feet.

[0142] Furthermore, the floor assembly 200 may also include a second sound insulation cotton 204, which can be laid on the rear floor 201, and the fifth duct 32 of the foot-blowing air duct 30 can be installed on the second sound insulation cotton 204. The second sound insulation cotton 204 can provide sound insulation and vibration damping for the rear floor 201 and the luggage compartment, thereby preventing abnormal noises. In addition, the second sound insulation cotton 204 can also provide sound insulation and vibration damping for the fifth duct 32.

[0143] Understandably, the thickness of the second sound insulation cotton 204 can be reduced; for example, the thickness of the second sound insulation cotton 204 can be greater than or equal to 2mm and less than or equal to 7mm. This is beneficial for increasing the size of the vehicle's interior space in the width direction. However, to achieve good NVH performance, it is necessary to increase the thickness of the sound insulation cotton in other areas to compensate for the sacrifice in acoustic package caused by the reduced thickness of the second sound insulation cotton 204.
