Description

Technical Field

[0001] The utility model relates to the technical field of automotive air conditioners, and particularly to an air duct system and an automobile. Background Art

[0002] In an automotive air conditioning system, an air duct is connected to the outlet of an automotive air conditioning box, mainly for guiding air, distributing the air from the air conditioning box to corresponding air outlets in the vehicle, and then blowing the air to the target area through the air outlets. In order to improve the comfort of passengers, existing air ducts generally include a face-blowing duct and / or a foot-blowing duct. The face-blowing duct directly blows cold air onto the faces of passengers, and the foot-blowing duct directly blows warm air onto the feet of passengers. However, in current such duct systems, each duct is generally independent, resulting in a relatively large overall occupied space and a relatively heavy overall weight. Summary of the Utility Model

[0003] The utility model aims to solve at least one of the above technical problems.

[0004] To solve the above problems, the utility model provides an air duct system for an air conditioner, including a transition duct and at least two face-blowing ducts. One end of the transition duct is used to communicate with the air outlet of an air conditioning main unit. At least two face-blowing ducts are arranged at intervals along the transverse direction of the vehicle, and one end of each face-blowing duct is respectively communicated with the transition duct. Each face-blowing duct is provided with a face-blowing air outlet.

[0005] The air duct system for an air conditioner provided by the utility model includes at least two face-blowing ducts with face-blowing air outlets. One end of each face-blowing duct is communicated with the transition duct. For example, when the air conditioning main unit blows out air during refrigeration, the air can pass through the transition duct and be sent to at least two face-blowing ducts respectively. When the two face-blowing ducts are arranged at intervals along the transverse direction of the vehicle, the face-blowing air outlet of the left face-blowing duct can blow cold air onto the face of the left passenger, and the face-blowing air outlet of the right face-blowing duct can blow cold air onto the face of the right passenger, enabling the faces of the left and right passengers to directly receive cold air, and providing a better cooling experience for passengers in hot weather. Among them, since multiple face-blowing ducts are all communicated with the air outlet of the air conditioning main unit through the transition duct, in other words, multiple face-blowing ducts are integrated together through the transition duct, with a relatively high overall integration degree, a compact structure, a relatively small occupied space, and a relatively light weight.

[0006] Further, the face-blowing duct extends along the longitudinal direction of the vehicle, and a plurality of the face-blowing air outlets are arranged at intervals along its extending direction.

[0007] Further, a damper mechanism is arranged between the face-blowing air outlet and the transition duct of the face-blowing duct.

[0008] Further, the air-conditioning duct system further includes two foot-blowing ducts each provided with a foot-blowing air outlet. The two foot-blowing ducts are respectively a first foot-blowing duct and a second foot-blowing duct. One end of the first foot-blowing duct is respectively communicated with the transition duct, and one end of the second foot-blowing duct is used for communicating with the air outlet of the air-conditioning main unit.

[0009] Further, a wind distribution mechanism is provided at the air outlet of the air-conditioning main unit. The wind distribution mechanism is used to adjust the communication or closing between the air outlet of the air-conditioning main unit and the transition duct and / or the second foot-blowing duct.

[0010] Further, a damper mechanism is provided between the corresponding foot-blowing air outlet of the first foot-blowing duct and the transition duct; and / or, a damper mechanism is provided between the corresponding foot-blowing air outlet of the second foot-blowing duct and the air-conditioning main unit; and / or, the two foot-blowing ducts are respectively arranged inside two vehicle body side panels, and a foot-blowing through hole is provided at the position of the vehicle body side panel corresponding to the foot-blowing air outlet.

[0011] Further, the damper mechanism includes a motor and a damper body, and the motor is used to drive the damper body to rotate.

[0012] Further, the transition duct includes a vertically extending portion and a horizontally extending portion. The bottom end of the vertically extending portion is communicated with the air outlet of the air-conditioning main unit, one end of the horizontally extending portion is communicated with the top end of the vertically extending portion, and one end of the two face-blowing ducts is respectively communicated with the two ends of the horizontally extending portion in a one-to-one correspondence.

[0013] Further, the air-conditioning main unit and the vertically extending portion are respectively arranged inside the vehicle body side panel, and the horizontally extending portion and the face-blowing ducts are both arranged inside the roof structure. Among them, the roof structure is provided with a face-blowing through hole corresponding to the face-blowing air outlet.

[0014] The present invention further provides an automobile, including an air-conditioning main unit and the air-conditioning duct system as described above. The air-conditioning main unit is communicated with one end of the transition duct of the air-conditioning duct system.

[0015] Since the technical improvement and technical effect of the automobile are the same as those of the air-conditioning duct system, the automobile will not be described in detail herein. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] It should be noted that the meanings represented by the foregoing X-axis, Y-axis, and Z-axis are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0029] See Figure 1-2 , an air duct system of an air conditioner according to an embodiment of the present invention includes a transition air duct 1 and at least two face-blowing air ducts 2. One end of the transition air duct 1 is used to communicate with the air outlet of an air conditioner main unit 3. At least two of the face-blowing air ducts 2 are arranged at intervals along the vehicle width direction, and one end of each of the face-blowing air ducts 2 is respectively communicated with the transition air duct 1. A face-blowing air outlet 23 is provided on each of the face-blowing air ducts 2.

[0030] In this embodiment, the air duct system of the air conditioner includes at least two face-blowing air ducts 2 having face-blowing air outlets 23. When at least two face-blowing air ducts 2 are arranged at intervals along the vehicle width direction, the faces of the vehicle occupants can receive cold air more evenly and directly, and the cooling feeling of the occupants is better when the weather is hot. For example, the air duct system of the air conditioner may include two face-blowing air ducts 2, namely a first face-blowing air duct 21 and a second face-blowing air duct 22. One end of each of these two face-blowing air ducts 2 is communicated with the transition air duct 1. For example, when the air conditioner main unit 3 cools and blows air, the air can pass through the transition air duct 1 and be sent to the two face-blowing air ducts 2 respectively. When the two face-blowing air ducts 2 are arranged at intervals along the vehicle width direction, the first face-blowing air duct 21 may be the face-blowing air duct on the left side, and the second face-blowing air duct 22 may be the face-blowing air duct on the right side. The face-blowing air outlet 23 of the face-blowing air duct 2 on the left side can blow cold air to the face of the occupant on the left side, and the face-blowing air outlet 23 of the face-blowing air duct 2 on the right side can blow cold air to the face of the occupant on the right side, so that the faces of the occupants on both the left and right sides directly receive cold air, and the cooling feeling of the occupants is better when the weather is hot. Among them, since the multiple face-blowing air ducts 2 are all communicated with the air outlet of the air conditioner main unit 3 through the transition air duct 1, in other words, the multiple face-blowing air ducts 2 are integrated together through the transition air duct 1, the overall integration degree is relatively high, the structure is compact, the occupied space is small, and the weight is light.

[0031] See Figure 1-2 , optionally, the face-blowing air duct 2 extends along the vehicle length direction, and a plurality of the face-blowing air outlets 23 are arranged at intervals along its extending direction.

[0032] In this embodiment, for a vehicle with three rows of seats, a plurality of face-blowing air outlets 23 are arranged at intervals along the vehicle length direction in the face-blowing air duct 2, for example, specifically two. In each face-blowing air duct 2, one face-blowing air outlet 23 is used to blow cold air to the face of the occupant in the third row of seats, and the other face-blowing air outlet 23 is used to blow cold air to the face of the occupant in the second row of seats.

[0033] Of course, in other embodiments, for a vehicle with three rows of seats, the face-blowing air duct 2 is provided with three face-blowing air outlets 23 at intervals in the longitudinal direction of the vehicle. The three face-blowing air outlets 23 are respectively used to blow cold air towards the faces of the occupants in the third row of seats, the second row of seats, and the first row of seats.

[0034] In this embodiment, for a vehicle with only two rows of seats, the face-blowing air duct 2 can also be provided with two face-blowing air outlets 23 at intervals in the longitudinal direction of the vehicle. The two face-blowing air outlets 23 are respectively used to blow cold air towards the faces of the occupants in the second row of seats and the first row of seats.

[0035] See Figure 3-5 , optionally, a damper mechanism 5 is provided between the face-blowing air outlet 23 and the transition air duct 1 of the face-blowing air duct 2.

[0036] In this embodiment, the damper mechanism 5 can have two states, namely an open state (as shown in Figure 5 ) and a closed state (as shown in Figure 4 ). When the damper mechanism is in the open state, the face-blowing air duct 2 is in a dredged state between the face-blowing air outlet 23 and the transition air duct 1. At this time, the air entering the transition air duct 1 from the air-conditioning main unit 3 can flow through the damper mechanism 5 and be blown out from the face-blowing air outlet 23; when the damper mechanism 5 is in the closed state, the face-blowing air duct 2 is in a cut-off state between the face-blowing air outlet 23 and the transition air duct 1, and the air in the transition air duct 1 cannot be blown out from the face-blowing air outlet 23.

[0037] In this embodiment, when the damper mechanism 5 is provided, for example, when there is an occupant in the left seat and no occupant in the right seat, the damper mechanism 5 on the right face-blowing air duct 2 can be in the closed state, and the damper mechanism 5 on the left face-blowing air duct 2 can be in the open state, so that the air entering the transition air duct 1 from the air-conditioning main unit 3 is more blown out from the face-blowing air outlet 23 of the left air duct to cool the face of the occupant on the left seat.

[0038] In this embodiment, when there is only one face-blowing air outlet 23 on the face-blowing air duct 2, the damper mechanism 5 can be provided at any position of the face-blowing air duct 2 between the face-blowing air outlet 23 and the transition air duct 1. For example, it can be provided at a position close to the face-blowing air outlet 23 or at a position close to the transition air duct 1.

[0039] When there is only one face-blowing air outlet 23 on the face-blowing air duct 2, preferably, the air door mechanism 5 is arranged at a position close to the transition air duct 1. In this way, when it is necessary to blow air from the face-blowing air outlet 23 of the face-blowing air duct 2, by controlling the air door mechanism 5 at this position to be in the closed state, it can not only ensure that the face-blowing air outlet 23 cannot blow air, but also ensure that the air in the transition air duct 1 will not be diverted to the corresponding transition air duct 1. For example, when there is an occupant in the left seat and no occupant in the right seat, the air door mechanism 5 on the right face-blowing air duct 2 can be controlled to be in the closed state, and the air door mechanism 5 on the left face-blowing air duct 2 can be controlled to be in the open state, so that the air entering the transition air duct 1 from the air conditioner main unit 3 will hardly enter the right face-blowing air duct 2, but more enter the left face-blowing air duct 2 to increase the air volume blown to the left occupant.

[0040] In this embodiment, when there are multiple face-blowing air outlets 23 on the face-blowing air duct 2, the air door mechanism 5 on the face-blowing air duct 2 is at least arranged between the face-blowing air outlet 23 closest to the transition air duct 1 and the transition air duct 1. To ensure that when the air door mechanism 5 at this position is in the closed state, each face-blowing air outlet 23 on this face-blowing air duct 2 cannot blow air; and to ensure that when the air door mechanism 5 at this position is in the open state, each face-blowing air outlet 23 on this face-blowing air duct 2 can blow air.

[0041] In other embodiments, when there are multiple face-blowing air outlets 23 on the face-blowing air duct 2, multiple air door mechanisms 5 can be arranged on the face-blowing air duct 2, that is, an air door mechanism 5 is arranged between the face-blowing air outlet 23 closest to the transition air duct 1 and the transition air duct 1, and an air door mechanism 5 is also arranged between adjacent two face-blowing air outlets 23. For example, there are two face-blowing air outlets 23 on the face-blowing air duct 2. The face-blowing air outlet 23 close to the transition air duct 1 is denoted as the first face-blowing air outlet, and the face-blowing air outlet 23 far from the transition air duct 1 is denoted as the second face-blowing air outlet. The air door mechanism 5 between the first face-blowing air outlet and the transition air duct 1 is denoted as the first air door mechanism 5, and the air door mechanism 5 between the second face-blowing air outlet and the first face-blowing air outlet is denoted as the second air door mechanism 5. Based on this, when there is no occupant in the second row of seats corresponding to the second face-blowing air outlet, and there is an occupant in the third row of seats corresponding to the first face-blowing air outlet, at this time, the second air door mechanism 5 can be controlled to be in the closed state, and the first air door mechanism 5 can be controlled to be in the open state, so that the air entering this face-blowing air duct 2 will be blown out from the first face-blowing air outlet and will not be lost from the second face-blowing air outlet, improving the comfort of the occupant in the third row of seats.

[0042] See Figure 1-2, optionally, the air-conditioning duct system further includes two foot-blowing ducts 4 each provided with a foot-blowing air outlet 43. The two foot-blowing ducts 4 are respectively a first foot-blowing duct 41 and a second foot-blowing duct 42. One end of the first foot-blowing duct 41 is respectively communicated with the transition duct 1, and one end of the second foot-blowing duct 42 is used for communicating with the air outlet of the air-conditioning main unit 3.

[0043] In this embodiment, like the face-blowing duct 2, the first foot-blowing duct 41 is also communicated with the transition duct 1. Since the air-conditioning main unit 3 is generally not arranged at the upper position of the vehicle (there is no space at the upper position), but is usually arranged at the lower position of the vehicle, and the foot-blowing duct 4 for blowing to the feet of the occupants is also at the lower position of the vehicle. Therefore, the second foot-blowing duct 42 here can be directly communicated with the air outlet of the air-conditioning main unit 3. And the air-conditioning main unit 3 is generally arranged close to one side body side plate. Therefore, the foot-blowing duct close to this side body side plate (the second foot-blowing duct 42) can be directly connected to the air-conditioning main unit 3, and the foot-blowing duct close to the other side body side plate (the first foot-blowing duct 41) is connected to the air-conditioning main unit 3 through the transition duct 1. Thus, the two face-blowing ducts 2, the transition duct 1, the two foot-blowing ducts 4 and the air-conditioning main unit 3 are integrated together, reducing the space occupation and virtually increasing the space of the occupant compartment. For example, the air-conditioning main unit 3 is arranged in the lower space of the right body structure. After one end of the transition duct 1 is connected to the air outlet of the air-conditioning main unit 3 at this position, the other end of the transition duct 1 can extend to the intersection position of the roof structure and the left body; at this time, the second foot-blowing duct 42 on the same side as the air-conditioning main unit 3 can also be arranged in the lower space of the right body structure to be directly connected to the air-conditioning main unit 1, while the first foot-blowing duct 41 on the other side is connected to the other end of the transition duct 1 to be indirectly connected to the air-conditioning main unit 3.

[0044] In this embodiment, since the air-conditioning duct system not only includes the face-blowing duct 2 for blowing to the face of the occupants by the user, but also includes the foot-blowing duct 4 for blowing to the feet of the occupants. Thus, the occupants can be blown simultaneously through the face-blowing duct 2 and the foot-blowing duct 4, for example, blowing cold air or warm air simultaneously to quickly cool down or warm up the occupants. In this embodiment, like the face-blowing duct 2, the foot-blowing duct 4 is also provided with two (the first foot-blowing duct 41 and the second foot-blowing duct 42 respectively). The first foot-blowing duct 41 and the first face-blowing duct 21 are on the same side (the left side in the figure), and the second foot-blowing duct 42 and the second face-blowing duct 22 are also on the same side (the right side in the figure). Thus, when needed, the left occupants can be blown simultaneously through the first foot-blowing duct 41 and the first face-blowing duct 21, and the right occupants can be blown simultaneously through the second foot-blowing duct 42 and the second face-blowing duct 22.

[0045] Optionally, a air distribution mechanism (not shown in the figure) is provided at the air outlet of the air conditioner main unit 3, and the air distribution mechanism is used to adjust the communication or closing between the air outlet of the air conditioner main unit 3 and the transition air duct 1 and / or the second foot blowing air duct 42.

[0046] In this embodiment, when one end of the transition air duct 1 and the second foot blowing air duct 42 are both communicated with the air outlet of the air conditioner main unit 3, an existing air distribution mechanism may be provided at the air outlet of the air conditioner main unit 3. This air distribution mechanism can make the air outlet of the air conditioner main unit 3 communicate only with the transition air duct 1, can also make the air outlet of the air conditioner main unit 3 communicate only with the second foot blowing air duct 42, and can also make the air outlet of the air conditioner main unit 3 communicate with both the transition air duct 1 and the second foot blowing air duct 42 at the same time. Since the air distribution mechanism can adopt an existing structure, the specific structure will not be described further.

[0047] In this embodiment, in the case of very cold winter, the occupants will feel more comfortable with warm air on their feet. At this time, the air conditioner main unit 3 can, through the heating mode, send the warm air only into the foot blowing air duct 4, and finally blow the warm air to the feet of the occupants through the foot blowing air outlet 43 of the foot blowing air duct 4. Among them, when there is only a right occupant and no left occupant, the air distribution mechanism can be used to make the air outlet of the air conditioner main unit 3 communicate only with the second foot blowing air duct 42 and not with the transition air duct 1. At this time, the air conditioner main unit 1 in the heating state will send the warm air only into the second foot blowing air duct 42 to blow air on the feet of the right occupant. When there is only a left occupant and no right occupant, the air distribution mechanism can be used to make the air outlet of the air conditioner main unit 3 communicate only with the transition air duct 1 and not with the second foot blowing air duct 42, and the air door mechanism 5 on the face blowing air duct 2 is closed. The air conditioner main unit 3 in the heating state will first send the warm air into the transition air duct 1, and then it can blow out only from the foot blowing air outlet of the first foot blowing air duct 41 to blow air on the feet of the right occupant. When there are occupants on both the left and right sides, make the air outlet of the air conditioner main unit 3 communicate with both the transition air duct 1 and the second foot blowing air duct 42 at the same time, and make the air door mechanism 5 on the face blowing air duct 2 closed. The air conditioner main unit 3 in the heating state will send part of the warm air into the second foot blowing air duct 42 to blow air on the feet of the right occupant. At the same time, the air conditioner main unit 3 will also send other part of the warm air into the transition air duct 1, and then the warm air entering the transition air duct 1 can blow out only from the foot blowing air outlet of the first foot blowing air duct 41 to blow air on the feet of the right occupant.

[0048] Optionally, an air door mechanism 5 is provided between the foot blowing air outlet 43 of the first foot blowing air duct 41 and the transition air duct 1; and / or, an air door mechanism 5 is provided between the corresponding foot blowing air outlet 43 of the second foot blowing air duct 42 and the air conditioner main unit 3.

[0049] In this embodiment, similar to the damper mechanism 5 provided on the face blowing air duct 2, a damper mechanism 5 is also provided on the first foot blowing air duct 41 communicating with the transition air duct 1. In this way, when the damper mechanism 5 on the first foot blowing air duct 41 is in the closed state, the first foot blowing air duct 41 is in a cut-off state between the corresponding foot blowing air outlet 43 and the transition air duct 1, and the air entering the transition air duct 1 cannot be blown out from the foot blowing air outlet 43; when the damper mechanism 5 on the first foot blowing air duct is in the open state, the first foot blowing air duct 41 is in a dredged state between the corresponding foot blowing air outlet 43 and the transition air duct 1, and the air entering the transition air duct 1 can be blown out from the foot blowing air outlet 43.

[0050] Based on the above two foot blowing air ducts 4 and face blowing air duct 2, as Figure 1-2 shown, the second foot blowing air duct 42 can be the right foot blowing air duct 4, and the first foot blowing air duct 41 is the left foot blowing air duct 4. If only the foot blowing air outlet 43 on the second foot blowing air duct 42 on the right needs to blow air, the air outlet of the air conditioner main unit 3 can be controlled to communicate only with the second foot blowing air duct 42 through the air distribution mechanism. If only the foot blowing air outlets 43 of the two foot blowing air ducts 4 need to blow air, then control the damper mechanism 5 to connect the air outlet of the air conditioner main unit 3 to both the second foot blowing air duct 42 and the transition air duct 1 at the same time, and control the damper mechanism 5 on the face blowing air duct 2 to be in the closed state to ensure that a sufficient amount of air is blown out from the foot blowing air outlets 43 of the two foot blowing air ducts 4. If the foot blowing air outlets 43 of the foot blowing air ducts 4 do not need to blow air, then control the air distribution mechanism to connect the air outlet of the air conditioner main unit 3 only to the transition air duct 1, then control the damper mechanism 5 on the first foot blowing air duct 41 to be in the closed state, and control the damper mechanism 5 on the second foot blowing air duct 42 to be in the closed state.

[0051] Refer to Figure 4-5 , optionally, the damper mechanism 5 includes a motor 52 and a damper body 51, and the motor 52 is used to drive the damper body 51 to rotate.

[0052] In this embodiment, whether it is the damper mechanism 5 on the face blowing air duct 2 or the damper mechanism 5 on the foot blowing air duct 4, the damper mechanism 5 includes a motor 52 and a damper body 51. The motor 52 is located outside the air duct, and the damper body 51 is located inside the air duct. The motor 52 is used to drive the damper body 51 to rotate. It can be understood that, as Figure 4 shown, the damper body 51 has a plate-like structure. When the motor 52 drives the damper body 51 to rotate to be perpendicular to the extending direction of the air duct, for example, when the damper body 51 rotates to the vertical state, the damper body 51 cuts off the corresponding air duct, and at this time the damper mechanism 5 is in the closed state; as Figure 5As shown, when the motor 52 drives the damper body 51 to rotate until it is parallel to the extending direction of the air duct, for example, when the damper body 51 rotates to a horizontal state, the damper body 51 dredges the corresponding air duct, and at this time, the damper mechanism 5 is in an open state. With the damper mechanism 5 of this structure, the structure is simple and reliable.

[0053] Optionally, the two foot blowing air ducts 4 are respectively arranged inside two vehicle body side panels. Blow foot openings are arranged at positions of the vehicle body side panels corresponding to the foot blowing air outlets 43, and the air conditioning main unit 3 is arranged inside the corresponding vehicle body side panel.

[0054] In this embodiment, as described above, the air conditioning main unit 3 can be arranged at a lower position of the vehicle, for example, specifically arranged inside the lower part of the vehicle body side panel, such as between the right rear wing of the right vehicle body side panel and the interior trim panel. At this time, the second foot blowing air duct 42 is also arranged between the right rear wing of the right vehicle body side panel and the interior trim panel, and blow foot openings corresponding to the corresponding foot blowing air outlets 43 are arranged on the interior trim panel of the right vehicle body side panel; the first foot blowing air duct 41 is arranged between the left rear wing of the left vehicle body side panel and the interior trim panel, and blow foot openings corresponding to the corresponding foot blowing air outlets 43 are arranged on the interior trim panel of the left vehicle body side panel.

[0055] See Figure 1 , optionally, the transition air duct 1 includes a vertically extending portion 11 and a horizontally extending portion 12. The bottom end of the vertically extending portion 11 is communicated with the air outlet of the air conditioning main unit 3, one end of the horizontally extending portion 12 is communicated with the top end of the vertically extending portion 11, and one ends of the two face blowing air ducts 2 are respectively and correspondingly communicated with both ends of the horizontally extending portion 12.

[0056] In this embodiment, as described above, the air conditioning main unit 3 is arranged at a lower position of the vehicle, while the face blowing air duct 2 for blowing towards the faces of the passengers is at a relatively high position. Therefore, the transition air duct 1 is designed to be composed of two parts here, namely the vertically extending portion 11 and the horizontally extending portion 12. The horizontally extending portion 12 can be at the same height or approximately the same height as the face blowing air duct 2. The transition air duct 1 is specifically communicated with the face blowing air duct 2 through the horizontally extending portion 12, and the transition air duct 1 is connected to the air conditioning main unit 3 at a lower position through the vertically extending portion 11.

[0057] Optionally, the air conditioning main unit 3 and the vertically extending portion 11 are respectively arranged inside the vehicle body side panel, the horizontally extending portion 12 and the face blowing air duct 2 are both arranged inside the roof structure, and a face blowing opening corresponding to the face blowing air outlet 23 is arranged on the roof structure.

[0058] In this embodiment, both the air-conditioning main unit 3 and the transition air duct 1 are arranged in the vehicle body structure.

Figure 6 As shown Figure 7 As shown

[0060] The present utility model further provides an automobile, which includes an air-conditioning main unit 3 and the air-conditioning air duct system as described above. One end of the transition air duct 1 of the air-conditioning air duct system is communicated with the air-conditioning main unit 3.

[0061] Since the technical improvement and technical effect of the automobile are the same as those of the air-conditioning air duct system, the automobile will not be described in detail herein.

[0062] Specifically, in this automobile, in addition to including the air-conditioning main unit 3 and the air-conditioning air duct system as described above, it may also include a traditional air-conditioning system. The air outlet of the traditional air-conditioning system is, for example, arranged at the instrument panel or the tail of the sub-instrument panel, mainly blowing air to the front-row passengers, and it is difficult to directly blow to the face or feet of the passengers; while the aforementioned air-conditioning air duct system can be arranged at the rear of the automobile. For example, the air-conditioning main unit 3 is arranged between the rear wing of the vehicle body side panel and the interior trim panel. The foot-blowing air outlet 43 of the foot-blowing air duct 4 directly blows to the feet of the passengers in the last row of seats, and the face-blowing air duct 2 can directly blow to the faces of the passengers in the last row of seats. When the automobile has three rows of seats, the face-blowing air duct 2 can directly blow to the faces of the passengers in the last row of seats and the second row of seats.

[0063] Optionally, in this vehicle, the aforementioned air-conditioning main unit 3 and the air-conditioning duct system can be electrically connected to the large vehicle screen. The occupant can first select an air-conditioning mode from the large vehicle screen, such as the full-blow mode, the full-face-blow mode (cooling mode), the partial-face-blow mode, the foot-blow mode (heating mode), and the partial-foot-blow mode, etc. After the air-conditioning controller receives this signal, the air-conditioning main unit 3 implements the corresponding mode. When implementing the corresponding mode, it is only necessary to control the air door mechanisms 5 on the corresponding ducts to be in the open state or the closed state. Among them, the full-blow mode means that all air outlets of all ducts blow air; the full-face-blow mode (cooling mode) means that each face-blow air outlet 23 of the two face-blow ducts 2 blows cold air, and the other air outlets do not blow air; the partial-face-blow mode means that only some of the face-blow air outlets 23 blow cold air, and the other air outlets do not blow air; the foot-blow mode (heating mode) means that each foot-blow air outlet 43 of the two foot-blow ducts 4 blows warm air, and the other air outlets do not blow air; the partial-foot-blow mode means that only some of the foot-blow air outlets 43 blow warm air, and the other air outlets do not blow air.

[0064] 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 at least one such feature.

[0065] Although the present utility model is disclosed as above, the protection scope of the present utility model is not limited thereto. Without departing from the spirit and scope of the present utility model, those skilled in the art can make various changes and modifications, and these changes and modifications will all fall within the protection scope of the present utility model.
