The embodiments described below by referring to the drawings are exemplary, only for explaining the utility model, and cannot be understood as limiting the utility model.

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0043] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] In related technologies, some cabin ventilation covers are designed without drainage channels. Due to the high degree of overlap between the drainage channel and the air intake channel, the entire water and air channel path is complex and the structure is large. This not only occupies limited cabin space but also increases the cabin weight.

[0046] In addition, the ends of the drainage channel and the air intake channel are located in the negative pressure zone of the air conditioner. When the air conditioner is working, the negative pressure will draw air from the end of the air intake channel and also draw air from the end of the drainage channel, causing the air conditioner to draw in water vapor and affecting the use of the air conditioner in the passenger cabin.

[0047] In view of this, such as Figures 1 to 4 As shown, this utility model embodiment provides an air intake and drainage device 100. The air intake and drainage device 100 is applied to a vehicle. The air intake and drainage device 100 can achieve water and air separation at the water and air inlet 1001, thereby simplifying the water and air channel path and structure.

[0048] Specifically, the air intake and drainage device 100 includes a ventilation cover 10, a machine cover 20, and a water-air separation structure 30.

[0049] The vent cover 10 is located at the lower side of the hood 20, and the vent cover 10 and the hood 20 jointly define a water-air inlet 1001 at the end close to the front windshield of the vehicle, which is used for the outside water flow and air flow to enter the inside of the air inlet drainage device 100.

[0050] As shown in Figure 3 The vent cover 10 has a water outlet 101 which is in communication with the water-air inlet 1001, and is used for the water flow flowing from the water-air inlet 1001 to flow outwards.

[0051] The hood 20 has a first air inlet part 221 which is in communication with the water-air inlet 1001.

[0052] The water-air separation structure 30 has a second air inlet part 30a which is in communication with the first air inlet part 221 and the air suction port of the air conditioner of the vehicle respectively.

[0053] The first air inlet part 221 is used for the air flow flowing from the water-air inlet 1001 to flow to the second air inlet part 30a after flowing from bottom to top through the first air inlet part 221, and the second air inlet part 30a is used for the air flow flowing from the first air inlet part 221 to flow to the air suction port of the air conditioner after flowing from bottom to top through the second air inlet part 30a.

[0054] The outside water flow enters the inside of the air inlet drainage device 100 through the water-air inlet 1001, and then flows outwards through the water outlet 101 on the vent cover 10, thereby forming a water flow path; the outside air flow enters the inside of the air inlet drainage device 100 through the water-air inlet 1001, and then flows to the air suction port of the air conditioner after sequentially passing through the first air inlet part 221 and the second air inlet part 30a, thereby forming an air flow path.

[0055] In this embodiment of the invention, in a first aspect, by providing a water outlet 101 on the lower ventilation cover 10 and a first air inlet 221 on the upper cover 20, and by connecting the first air inlet 221 to the air intake of the air conditioner via a second air inlet 30a, the water flow path and the airflow path in the air intake and drainage device 100 are separated. Thus, after the water flow and airflow enter the interior of the air intake and drainage device 100 through the water and air inlets 1001, the water flow can be discharged outward through the lower water outlet 101, and the airflow can flow towards the air intake of the air conditioner through the upper first air inlet 221. That is, water and airflow are separated upon passing through the water and air inlets 1001, avoiding overlap between the water flow path and the airflow path, and simplifying the water and air passage path of the air intake and drainage device 100. In terms of structure, the intake and drainage device 100 reduces the space occupied by the cabin, thereby reducing the weight of the cabin; secondly, by utilizing the first intake 221 and the second intake 30a, the airflow needs to climb upwards when passing through the first intake 221, and the airflow needs to climb upwards again when passing through the second intake 30a. In this way, the resistance of water vapor attached to the airflow through the first intake 221 and the second intake 30a is increased, making it easier for water vapor to fall downwards under its own weight when passing through the first intake 221 and the second intake 30a, reducing the amount of water vapor passing through the first intake 221 and the second intake 30a, thereby reducing the water vapor content in the airflow flowing into the air intake of the air conditioner, and reducing the adverse effects of water vapor on the use of the air conditioner.

[0056] Regarding the aforementioned ventilation cover 10, such as Figure 3 As shown, in some embodiments, the ventilation cover 10 includes a first cover plate 11 and a second cover plate 12. The first cover plate 11 is connected to the windshield of the vehicle, and the second cover plate 12 is connected to the end of the first cover plate 11 away from the windshield of the vehicle. The first cover plate 11 and the second cover plate 12 together define a water receiving groove 102. The water receiving groove 102 is connected to a water inlet 1001 and a water outlet 101, respectively. The water outlet 101 is located at the bottom of the water receiving groove 102. After the external water flows into the interior of the air intake and drainage device 100 through the water inlet 1001, it can flow along the first cover plate 11 into the water receiving groove 102 and be discharged outward through the water outlet 101.

[0057] In some embodiments, the air intake drainage device 100 further includes a first water outlet pipe 40. One end of the first water outlet pipe 40 is connected to the water outlet 101, and the other end of the first water outlet pipe 40 extends downward. The first water outlet pipe 40 is used to allow water flow at the water outlet 101 to pass through and be discharged outside the engine compartment. After the external water flow enters the interior of the air intake drainage device 100 through the water inlet 1001, it passes through the water receiving tank 102, the water outlet 101, and the first water outlet pipe 40 in sequence before being discharged outside the engine compartment, thus forming a water flow path. With the above arrangement, the external water flow can directly pass from top to bottom through the water inlet 1001, the water receiving tank 102, the water outlet 101, and the first water outlet pipe 40 before being discharged outside the engine compartment. The water flow path does not need to extend to the front of the engine compartment, making full use of the height space of the engine compartment and making the water flow path more compact in the longitudinal direction of the engine compartment.

[0058] Regarding the aforementioned hood 20, as Figure 4 As shown, in some embodiments, the hood 20 includes an upper cover 21 and a lower cover 22. The upper cover 21 is located above and connected to the lower cover 22. The upper cover 21 and the lower cover 22 together define an air vent 201. The upper cover 21 and the end of the first cover plate 11 near the windshield of the vehicle together define the aforementioned water vapor inlet 1001. The lower cover 22 includes an air outlet 222 and the aforementioned first air inlet 221. The air outlet 222 is far away from the water and air inlet 1001 relative to the first air inlet 221. The first air inlet 221 defines the air inlet 202, and the air outlet 222 defines the air outlet 203. The air chamber 201 is connected to the air inlet 202 and the air outlet 203 respectively. The air outlet 203 is connected to the second air inlet 30a. After the external airflow enters the interior of the air intake and drainage device 100 through the water and air inlet 1001, it flows towards the air intake of the air conditioner after passing through the air inlet 202, the air chamber 201, the air outlet 203 and the second air inlet 30a in sequence, thus forming an airflow path.

[0059] In some embodiments, the first air intake 221 includes a guide section 2211 and an air intake section 2212. The guide section 2211 is connected to the air intake section 2212. The air intake section 2212 is away from the water and air inlet 1001 relative to the guide section 2211. The air intake section 2212 defines the aforementioned air inlet 202. The air inlet 202 is connected to the water and air inlet 1001. The guide section 2211 is used to guide the airflow through the water and air inlet 1001 to the lower side of the air inlet 202. The air inlet 202 is used to allow the airflow to pass through the air inlet 202 from bottom to top. In this way, after the airflow enters the interior of the air intake and drainage device 100 through the water and air inlet 1001, it can quickly flow along the surface of the guide section 2211 to the lower side of the air inlet 202, and climb upwards before passing through the air inlet 202, thereby improving the air intake efficiency of the air inlet 202.

[0060] In some embodiments, the flow guide section 2211 extends upwardly and obliquely towards the water vapor inlet 1001, that is, the flow guide section 2211 is arranged at an angle with the horizontal plane, and the opening of the angle is towards the side where the water vapor inlet 1001 is located, and the angle is an acute angle. In this way, the flow guide section 2211 can guide the airflow passing through the water vapor inlet 1001. After the airflow passes through the water vapor inlet 1001 and enters the inside of the air inlet drainage device 100, the airflow can flow obliquely downward along the surface of the flow guide section 2211 to the lower side of the position where the air inlet section 2212 is located.

[0061] As shown in Figure 5 some embodiments, the air inlet 202 is provided with opposite windward side walls 2021 and leeward side walls 2022. The leeward side wall 2022 is closer to the flow guide section 2211 than the windward side wall 2021. The lower end of the windward side wall 2021 is horizontally aligned with the lower end of the leeward side wall 2022, or the upper end of the windward side wall 2021 is higher than the lower end of the leeward side wall 2022, and the lower end of the windward side wall 2021 is lower than the lower end of the leeward side wall 2022. In this way, the airflow can pass through the air inlet 202 from the lower side of the air inlet 202 upwardly, avoiding the airflow at the lower side of the air inlet 202 passing through the air inlet 202 directly in the horizontal direction. At the same time, limiting the height of the end of the windward side wall 2021 and the height of the end of the leeward side wall 2022 can reduce the height of the airflow climbing upwardly from the lower side of the air inlet 202 into the air inlet 202, so that the airflow is easy to pass through the air inlet 202 from the lower side of the air inlet 202, and the air inlet efficiency of the air inlet 202 is ensured.

[0062] In some embodiments, the air inlet drainage device 100 further comprises a first grid 50. The first grid 50 is installed in the air inlet 202, and the grids in the first grid 50 separate the air inlet 202 to form a plurality of small openings. By providing the first grid 50, foreign matters in the external environment can be effectively blocked from passing through the air inlet 202, and the airflow flow can be optimized, and the noise generated when the airflow passes through the air inlet 202 can be reduced.

[0063] In some embodiments, the windward side wall 2021 and the leeward side wall 2022 are respectively opposite two inner side walls of the first grid 50.

[0064] As shown in Figure 4 some embodiments, the connection between the flow guide section 2211 and the air inlet section 2212 is a circular arc transition. In this way, the surface at the connection between the air inlet section 2212 and the flow guide section 2211 is a smooth arc surface structure. When the airflow flows along the surface of the flow guide section 2211 and passes through the arc surface structure, the airflow can be smoothly transitioned to the lower side of the air inlet section 2212, and the flow smoothness of the airflow from the flow guide section 2211 to the air inlet section 2212 is improved.

[0065] As shown in Figure 4 andFigure 6 As shown, in some embodiments, the water-air separation structure 30 defines an air passage 301, an air inlet end 3011 of the air passage 301 is in communication with the first air inlet portion 221, an air outlet end 3012 of the air passage 301 is in communication with the air inlet of the air conditioner, the second air inlet portion 30a is in communication with the air passage 301 and is arranged between the air inlet end 3011 and the air outlet end 3012, the airflow flowing out of the first air inlet portion 221 enters the air passage 301 through the air inlet end 3011, then climbs up along the second air inlet portion 30a from bottom to top, and finally flows to the air inlet of the air conditioner through the air outlet end 3012.

[0066] Specifically, the air inlet end 3011 is in communication with the air outlet 203, the airflow from the outside enters the interior of the air-water inlet 100 through the water-air inlet 1001, then sequentially passes through the air inlet 202, the air cavity 201, the air outlet 203 and the air passage 301 (wherein the airflow passes through the second air inlet portion 30a between the air inlet end 3011 and the air outlet end 3012), and finally flows to the air inlet of the air conditioner, thereby forming an airflow path.

[0067] In some embodiments, the water-air separation structure 30 includes a shell 31 and a partition plate 32. The partition plate 32 is arranged in the interior of the shell 31, and the partition plate 32 and the shell 31 jointly define the above-mentioned air passage 301, the air passage 301 is located on the opposite sides of the partition plate 32, and the air inlet end 3011 and the air outlet end 3012 respectively penetrate the shell 31. By arranging the partition plate 32, a “labyrinth” structure is formed in the interior of the water-air separation structure 30, so that the flow path of the airflow in the water-air separation structure 30 can be prolonged, thereby making it easier for water vapor to separate from the airflow in the interior of the water-air separation structure 30.

[0068] In some embodiments, the shell 31 includes a bottom wall 311, and opposite first and second side walls 312 and 313. The bottom wall 311 is connected with the lower ends of the first and second side walls 312 and 313 respectively, one end of the partition plate 32 is connected with the first side wall 312, the other end of the partition plate 32 extends towards the second side wall 313 and is arranged in a spaced manner with the second side wall 313, the other end of the partition plate 32 is provided with a downward extending lower extension 321, the bottom wall 311 is provided with an upward extending upper extension 3111, the upper extension 3111 is located on the side of the lower extension 321 away from the second side wall 313, and the lower extension 321 and the upper extension 3111 jointly define the second air inlet portion 30a. In this way, when the airflow passes between the lower extension 321 and the upper extension 3111, the lower extension 321 and the upper extension 3111 can jointly guide the airflow to climb upwards, and finally flow to the air inlet of the air conditioner through the air outlet end 3012.

[0069] In some embodiments, the horizontal height of the upper end of the upper extending section 3111 is greater than or equal to the horizontal height of the lower end of the lower extending section 321, so that the airflow can be ensured to flow upwards from the lower side of the air outlet end 3012 and then pass through the air outlet end 3012, avoiding the airflow in the air passage 301 bypassing the lower extending section 321 and then directly passing through the air outlet end 3012 in the horizontal direction.

[0070] In some embodiments, the shell 31 includes a bottom wall 311, and opposite first and second side walls 312 and 313. The bottom wall 311 is connected to the lower ends of the first and second side walls 312 and 313, respectively. One end of the partition plate 32 is connected to the first side wall 312, and the other end of the partition plate 32 extends towards the second side wall 313 and is spaced apart from the second side wall 313. The shell 31 further includes opposite third and fourth side walls 314 and 315. The third side wall 314 is connected to one side of the first and second side walls 312 and 313, and the fourth side wall 315 is connected to the other side of the first and second side walls 312 and 313. At least one of the first and second side walls 312 and 313 and the partition plate 32 define a gap 302, and the gap 302 is in communication with the air inlet end 3011 and the air outlet end 3012, respectively. Thus, after the airflow enters the interior of the shell 31 through the air inlet end 3011, part of the airflow can flow along the air passage 301 and then pass through the second air inlet portion 30a and then be discharged from the air outlet end 3012, and the other part of the airflow can directly pass through the gap 302 and then be discharged from the air outlet end 3012. That is, the other part of the airflow does not need to flow along the air passage 301 and between the lower extending section 321 and the upper extending section 3111, thereby improving the flow rate of the other part of the airflow, and thus the air passage capacity of the water-air separation structure 30 can be improved to meet the large air intake requirement of the air intake of the air conditioner.

[0071] Specifically, the upper ends of the first, second, third and fourth side walls 312, 313, 314 and 315 jointly define the air inlet end 3011; and the bottom wall 311 defines the air outlet end 3012.

[0072] As shown in Figure 7 In some embodiments, the water-air separation structure 30 defines a water outlet 303, which is located on the lower side of the second air inlet portion 30a and is in communication with the second air inlet portion 30a. The water outlet 303 is used for discharging the liquid in the interior of the water-air separation structure 30 to the outside, so as to avoid water accumulation in the interior of the water-air separation structure 30.

[0073] When the airflow passes through the second air inlet portion 30a, the water vapor attached to the airflow will fall downward under the action of its own gravity to the lower side of the second air inlet portion 30a and slowly gather into water flow or water droplets flowing to the water outlet 303.

[0074] Specifically, the bottom wall 311 defines the water outlet 303.

[0075] As shown in Figure 4 some embodiments, the air inlet drainage device 100 further comprises a second grid 60. The second grid 60 is installed on the air inlet end 3011, and the grids in the second grid 60 separate the air inlet end 3011 to form a plurality of small openings. By providing the second grid 60, foreign matter from the outside can be effectively blocked from entering through the air inlet end 3011, and the air flow can be optimized to reduce noise generated when the air flow passes through the air inlet end 3011.

[0076] As shown in Figure 3 and Figure 4 some embodiments, the air inlet drainage device 100 further comprises a sealing member 70, which is sealingly connected between the cover 20 and the ventilation cover 10. The sealing member 70 is used to prevent the water flow and the air flow flowing in from the water-air inlet 1001 from entering the gap between the cover 20 and the ventilation cover 10 into the second air inlet portion 30a, so that the water flow and the air flow are separated by the water outlet 101 on the lower side and the air inlet 202 on the upper side, respectively, after entering the inside of the air inlet drainage device 100 through the water-air inlet 1001.

[0077] Specifically, the sealing member 70 is sealingly connected between the second cover plate 12 and the lower cover 22.

[0078] It should be noted that since the water-air separation structure 30 has a water-air separation function, even if the sealing member 70 fails after long-term use, causing part of the water flow and the air flow to directly enter the water-air separation structure 30 through the gap between the cover 20 and the ventilation cover 10, the second air inlet portion 30a can still prevent the water flow and the water vapor from flowing to the air inlet of the air conditioner.

[0079] In a second aspect, the embodiments of the present application also provide a vehicle, which comprises the air inlet drainage device 100 as described above.

[0080] It should be noted that the vehicle referred to in the embodiments of the present application can be a private car, such as a sedan, an SUV, an MPV, or a pickup truck, etc. The vehicle can also be a commercial vehicle, such as a minibus, a bus, or a truck, etc. The vehicle can be a gasoline vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0081] It should be noted that the vehicle provided in the embodiments of the present application only shows the parts related to the technical problems to be solved by the embodiments of the present application. It should be understood that the vehicle provided in the embodiments of the present application also includes other structures for realizing the functions of the vehicle, including but not limited to a vehicle body, etc.

[0082] Within the knowledge of those skilled in the art, various changes can be made without departing from the spirit of the present application. Furthermore, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
