Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
As shown in fig. 1 to 4, a first aspect of the embodiment of the present application provides an air duct assembly 100, where the air duct assembly 100 is applied to a vehicle, and the air duct assembly 100 includes an air outlet member, a first interior trim panel 110, and an air suction member 120.
The air outlet (not shown) is used to blow air to ventilate, heat, or cool the passenger compartment. The air outlet member may be a general air duct used in an existing vehicle air conditioning system, for example, a cylindrical structure or other irregular elongated shape, which is not limited herein. The air outlet member may have one or more air outlets, which are usually disposed in a front row of the passenger compartment of the vehicle, and the air outlets communicate with the passenger compartment.
The first interior trimming panel 110 may be a door panel, a roof panel, or the like, and the first interior trimming panel 110 is provided with a first exhaust opening 110a, and the first exhaust opening 110a is communicated with the ambient atmosphere. When the vehicle is in the external circulation mode, external air is blown to the passenger compartment through the air outlet member, so that the passenger compartment is slightly pressurized, and air in the passenger compartment is exhausted from the first exhaust port 110a to the external ambient atmosphere. In order to improve the air quality of the rear row of the passenger compartment, the first exhaust port 110a is provided in the rear row of the passenger compartment so that the air blown out of the air outlet member flows toward the rear row of the passenger compartment.
The suction member 120 has an inlet 120a and an outlet 120b, and the inlet 120a is communicated with the first exhaust opening 110a, so that the air flowing out of the outlet opening of the air outlet member is exhausted to the ambient atmosphere through the suction member 120. That is, the inlet 120a communicates with the passenger compartment, the suction member 120 may generate a negative pressure, and the suction member 120 sucks air at the rear row of the passenger compartment through the first air outlet 110a to accelerate the flow of the air at the rear row of the passenger compartment.
Note that the passenger compartment front row refers to the first row of the vehicle, and the passenger compartment rear row may be the second, third, fourth, or the like of the vehicle.
In summary, since the first exhaust opening 110a is disposed at the rear row of the passenger compartment, the inlet 120a of the air suction element 120 is communicated with the first exhaust opening 110a, and the air suction element 120 sucks air at the rear row of the passenger compartment through the first exhaust opening 110a, so that air in the passenger compartment is exhausted to the ambient atmosphere as soon as possible, thereby accelerating air flow at the rear row of the passenger compartment, improving air quality at the rear row by changing an air flow field, and improving comfort of passengers at the rear row.
Referring again to fig. 1-4, in some embodiments, the duct assembly 100 further includes a second interior trim panel 130, and the second interior trim panel 130 defines a second air outlet 130a. The air suction piece 120 is provided with a tapered section 120c, a connecting section 120d and a divergent section 120e which are sequentially communicated, along the direction from the tapered section 120c to the divergent section 120e, the flow cross-sectional area of the tapered section 120c is gradually reduced, and the flow cross-sectional area of the divergent section 120e is gradually increased. I.e., the suction element 120 is shaped like a venturi tube, and the connecting section 120d corresponds to the throat of the venturi tube. The tapering section 120c is communicated with the second exhaust outlet 130a, the inlet 120a is disposed at the connecting section 120d, the connecting section 120d is communicated with the first exhaust outlet 110a, and the outlet 120b is disposed at one end of the tapering section 120e far away from the tapering section 120 c. When the air flows through the second air outlet 130a through the tapered section 120c and the connecting section 120d, the air flow rate at the connecting section 120d increases and the pressure decreases, negative pressure is formed at the connecting section 120d, at this time, the connecting section 120d injects the air of the first air outlet 110a communicated with the connecting section 120d, the flow of the air around the first air outlet 110a is accelerated, and the tapered section 120e is used for reducing the air flow rate and reducing the noise of air exhaust. The present embodiment can improve the air quality of the rear discharge without a power source by using the exhaust gas discharged from the second air outlet 130a outside the passenger compartment as kinetic energy. Of course, the air suction member 120 may also be a suction fan or other device having a power source, and the purpose of accelerating the convection of the air discharged from the rear of the passenger compartment can also be achieved by active suction.
In an alternative embodiment, the air suction member 120 may not have the connecting section 120d, but only have the tapered section 120c and the tapered section 120e, so as to save the cost and reduce the volume of the air suction member 120. For example, the suction element 120 has a tapering section 120c and a diverging section 120e connected in sequence, and along the direction from the tapering section 120c to the diverging section 120e, the flow cross-sectional area of the tapering section 120c gradually decreases, and the flow cross-sectional area of the diverging section 120e gradually increases. The end of the tapering section 120c away from the diverging section 120e is communicated with the second air outlet 130a, the inlet 120a is disposed at the end of the tapering section 120c close to the diverging section 120e, or the inlet 120a is disposed at the end of the diverging section 120e close to the tapering section 120c, and the outlet 120b is disposed at the end of the diverging section 120e away from the tapering section 120 c. When the airflow flows through the tapered section 120c, the airflow velocity at the tapered section 120c is increased and the pressure is reduced, negative pressure is formed at the tapered section 120c, and at this time, the tapered section 120c injects the air of the first exhaust port 110a communicated with the tapered section to accelerate the flow of the air around the first exhaust port 110a, so that the air flow field is improved, and the comfort of passengers at the rear row is improved. Of course, the end of the gradually expanding section 120e close to the gradually reducing section 120c is also under negative pressure, and the inlet 120a is disposed therein and can also inject the air of the first exhaust opening 110a communicated therewith.
As shown in fig. 3 and 4, in some embodiments, the air duct assembly 100 further includes a cover 140 and an air duct 150.

One end of the air guide tube 150 is connected to the cover 140 and is connected to the air collection chamber, and the other end of the air guide tube 150 is connected to the air suction device 120 corresponding to the inlet 120 a. The fastening cover 140 and the air duct 150 are mainly used to communicate the first exhaust opening 110a and the connecting section 120d, so as to guide the air in the first exhaust opening 110a to flow to the connecting section 120d.
As shown in fig. 4, in some embodiments, the air suction member 120 is disposed on the second interior trim panel 130, a side of the air suction member 120 facing the second interior trim panel 130 has an opening, and the air suction member 120 and the second interior trim panel 130 surround to form an exhaust air duct 120f. The exhaust duct 120f is a passage formed by the tapered section 120c, the connecting section 120d, and the diverging section 120 e. The air suction piece 120 is provided with an opening, so that the thickness of the air suction piece 120 can be reduced, the material can be saved, and the production cost can be reduced. It should be noted that the second interior board 130 and the first interior board 110 may be integrated or separated, for example, the second interior board 130 and the first interior board 110 may be different portions of the same plaque, and specifically, the second interior board 130 and the first interior board 110 may be different portions of a C-pillar lower plaque.
In some embodiments, the second air outlet 130a is provided in the trunk room. Specifically, a portion of the C-pillar lower trim panel is located in the luggage compartment, and another portion is located in the passenger compartment. The second exhaust port 130a is provided in the trunk room to promote the air flow of the front row toward the rear row, and to minimize the exhaust noise of the air suction member 120 from being transmitted to the passenger room, by being provided away from the passenger room. In the case of SUV, MPV, and other types of vehicles, the luggage compartment and the passenger compartment are in full communication, and in the case of passenger vehicles, the luggage compartment and the passenger compartment are substantially in communication because they are difficult to completely isolate. Therefore, the second air outlet 130a is provided in the trunk room without affecting its normal air discharge. Of course, the second air outlet 130a may also be disposed in the passenger compartment, and only the position of the second air outlet 130a far from the headrest of the rear seat 200 compared to the first air outlet 110a is needed, and the air in the first air outlet 110a is sucked by the air suction member 120 by using the air exhaust power of the second air outlet 130a, so as to accelerate the air exhaust speed of the first air outlet 110 a.
As shown in fig. 5, in some embodiments, the second interior decoration plate 130 includes a sloping plate 131 and a vertical plate 132 connected to the sloping plate 131, the sloping plate 131 is disposed above the vertical plate 132, the second air outlet 130a is opened on the sloping plate 131, a part of the air draft part 120 abuts against the sloping plate 131, and another part abuts against the vertical plate 132. The inclined plate 131 may provide a certain supporting force to the suction element 120, so that the suction element 120 may be relatively stably fixed to the first trim panel 110.
In some embodiments, the cover 140 is snap-fitted to the first interior trim panel 110, and the suction element 120 is snap-fitted to the second interior trim panel 130. Through the clamping manner, the assembly of the buckle cover 140 and the first interior trim panel 110 becomes simple and convenient, and the assembly of the air suction piece 120 and the second interior trim panel 130 becomes simple and convenient, so that the production efficiency is improved.
