[0032] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] Reference below Figure 1-Figure 3 A water flow channel structure 100 according to an embodiment of the first aspect of the utility model is described.

[0034] like Figure 3 As shown, according to the water trough structure 100 of the embodiment of the utility model, the water trough structure 100 includes: a cover plate 10, a water trough body 20 and a water guide 30.

[0035] Specifically, the cover plate 10 has a grille hole 11 that passes through the cover plate 10, for example, the cover plate 10 has a grille hole 11 that passes through the cover plate 10 in the up-down direction. The water trough body 20 is connected to the cover plate 10, and the water trough body 20 has a cavity 21, the top of the cavity 21 is open to form an open opening 22, and the open opening 22 is opposite to and communicates with the grille hole 11, and an air inlet 24 is formed on the water trough body 20.

[0036] The water guide 30 is connected to the cover plate 10 and / or the water trough body 20 . The water guide 30 is disposed in the cavity 21 . The water guide 30 is disposed between the grille hole 11 and the air inlet 24 to separate the grille hole 11 from the air inlet 24 .

[0037] like Figure 3 As shown, the cover plate 10 is located at the upper part of the water trough structure 100, and is located above the water trough body 20 and connected to the water trough body 20. The cover plate 10 is provided with a grille hole 11, and the outside air can enter the water trough structure 100 through the grille hole 11 to be used as the source of automobile air conditioning gas. At the same time, the cover plate 10 can prevent large particles other than rainwater and other liquids from entering the water trough structure 100, effectively ensuring the cleanliness and hygiene of the water trough structure 100.

[0038] The water trough body 20 is located at the lower side of the cover plate 10 and is connected to the cover plate 10. The water trough body 20 forms a cavity, and the upper part of the cavity 21 is opened as an open mouth 22. For example, the water trough body 20 may include a front side plate, a rear side plate, a left side plate, a right side plate and a lower side plate, and the front side plate, the rear side plate, the left side plate, the right side plate and the lower side plate surround the cavity 21.

[0039] The cavity 21 is connected to the grille hole 11 through the opening 22, and is connected to the interior of the vehicle through the air inlet 24. External air can enter the interior of the vehicle through the grille hole 11, the opening 22, the cavity 21 and the air inlet 24 in sequence.

[0040] The water guide member 30 is connected to the cover plate 10 and / or the water trough body 20. The water guide member 30 may be connected to both the cover plate 10 and the water trough body 20; the water guide member 30 may be connected to the water trough body 20 but not to the cover plate 10; or the cover plate 10 may be connected to the water guide member 30.

[0041] The water guide 30 is located in the cavity 21 . For example, the water guide 30 may be a component extending in the left-right direction. The water guide 30 is disposed between the grille hole 11 and the air inlet 24 to separate the grille hole 11 from the air inlet 24 .

[0042] When the water flow channel structure of this embodiment is applied to a vehicle, rainwater enters the cavity 21 through the grille hole 11 and the open mouth 22 of the water flow channel body 20. Since the water guiding member 30 is located between the grille hole 11 and the air inlet 24 and separates the grille hole 11 from the air inlet 24, due to the blocking effect of the water guiding member 30, the rainwater entering the cavity 21 cannot directly enter the air inlet 24 with the flow of air, but is blocked by the water guiding member 30 on the side away from the air inlet 24. Through the guiding effect of the water guiding member 30, the rainwater is guided to the bottom of the cavity 21 and finally discharged from the cavity 21. As a result, rainwater can be effectively prevented from reaching the air inlet 24 and from entering the air inlet pipe 40 from the air inlet 24.

[0043] At the same time, after the air enters the cavity 21 through the grille hole 11 and the open mouth 22, due to the blocking effect of the water guide member 30, the air cannot directly reach the air inlet 24, but bypasses the water guide member 30 in the cavity 21, reaches the side of the water guide member 30 facing the air inlet 24, and finally enters the air inlet duct 40 from the air inlet 24 for use inside the vehicle.

[0044] According to the novel water flow channel structure 100 used in the present invention, a water guide member 30 is arranged in the water flow channel body 20, and the water guide member 30 is blocked between the grille hole 11 and the air inlet 24. Therefore, not only can air smoothly enter the air inlet 24, but also rainwater can be prevented from entering the interior of the vehicle through the air inlet 24, thereby preventing rainwater from entering the automobile air-conditioning system.

[0045] According to some embodiments of the present invention, referring to Figure 2 As shown, the cover plate 10 is disposed on the upper side of the water trough body 20, the air inlet 24 passes through the rear side wall of the cavity 21, and the water guide 30 is arranged in front of the air inlet 24 and shields the air inlet 24. Thus, the layout structure of the water trough structure 100 can be simplified and optimized, and the difficulty of production and assembly can be reduced, while preventing rainwater from directly entering the air inlet 24 through the grille hole 11.

[0046] For example, the grille hole 11 penetrates the cover plate 10 in the up-down direction, the air inlet 24 penetrates the rear side plate of the water trough body 20 in the front-to-back direction, the water guide 30 is located in front of the air inlet 24, and the water guide 30 is opposite to the grille hole 11 in the up-down direction and opposite to the air inlet 24 in the front-to-back direction.

[0047] According to some embodiments of the present invention, in a projection plane perpendicular to the front-rear direction, the projection of the air inlet 24 is located within the projection of the water guide 30 .

[0048] That is to say, in the front-to-rear direction, the water guiding member 30 can completely cover the air inlet 24, so that the air entering the cavity 21 from the grille hole 11 needs to bypass the left and right sides or the bottom of the water guiding member 30 to reach the position of the air inlet 24, and enter the interior of the vehicle through the air inlet 24. At the same time, rainwater passes through the grille hole 11 and the open mouth 22, flows along the water guiding member 30, and flows into the bottom of the cavity 21, thereby further effectively isolating rainwater from air.

[0049] In this embodiment, the projection of the air inlet 24 is arranged to be located within the projection of the water guide member 30, so that the shielding range of the air inlet by the water guide member in the front-to-back direction can be increased, and rainwater in the projection area directly in front of the air inlet 24 and in the projection area of ​​the water guide member 30 around the air inlet 24 can be separated, thereby preventing rainwater from entering the air inlet pipe 40.

[0050] According to some embodiments of the utility model, the water guide member 30 is formed with a water guide groove 31, the top of the water guide groove 31 is opened to form a top opening 32, the top opening 32 is opposite to and connected with the grille hole 11 up and down to receive the water flowing down from the grille hole 11, and the water guide outlet 34 of the water guide groove 31 is connected with the cavity 21 and is staggered with the air inlet 24.

[0051] For example Figure 2 and Figure 3 As shown, the water guide 30 is formed with a water guide groove 31 extending left and right, the top of the water guide 31 is open to form a top opening 32, the top opening 32 is opposite to the grille hole 11 up and down and is connected to receive the water flowing down from the grille hole 11, the water guide 30 is formed with a water guide outlet 34, the water guide groove 31 is connected to the cavity 21 located at the lower side of the water guide 30 through the water guide outlet 34, the water guide 30 is spaced apart from the air inlet 34 in the front-to-back direction, and the water guide outlet 34 of the water guide 30 is staggered with the air inlet 24 in the left-right direction. Further, in the up-down direction, the water guide outlet 34 is located and arranged below the air inlet 24.

[0052] When rainwater flows into the water flow channel structure 100 from the grille hole 11, the rainwater enters the water flow channel 31 through the top opening 32 of the water flow channel 31, but does not directly enter the cavity. Then, under the guidance of the water flow channel 31, the rainwater flows to the cavity 21 located below the water guide member 30 through the water guide outlet 34 for temporary storage. At the same time, when air enters the water flow channel structure 100 through the grille hole 11, the air enters the water flow channel 31 through the grille hole 11 and the top opening 32 of the water flow channel 31, and under the guidance of the water flow channel 31, the air flows from the water guide outlet 34 to the cavity 21. The air entering the cavity 21 bypasses the water guide member 30 and arrives at the air inlet 24 located at the rear side of the water guide member 30, and enters the air inlet pipe 40 through the air inlet 24.

[0053] In this embodiment, by forming a water guide groove 31 on the water guide member 30 , rainwater can be directly guided to the bottom of the cavity 21 through the water guide groove 31 , thereby further improving the guiding effect on rainwater entering the water flow channel structure 100 and further preventing rainwater from entering the air inlet 24 .

[0054] According to some embodiments of the present invention, the water guide 30 extends in the left-right direction, and at least one end of the water guide 30 in the left-right direction is open to form a water guide outlet 34 .

[0055] Reference Figure 3 The water guide member 30 extends in the left-right direction, so that the water guide member 30 can receive the rainwater flowing in through the grille hole 11 to the maximum extent, and prevent this part of the rainwater from flowing into the cavity 21 on the front side of the air inlet 24.

[0056] The water guiding member 30 can be open on the left or right side to form an open opening 22, or an open opening 22 can be set on both sides. By opening at least one end of the water guiding member 30 in the left and right directions to form a water guiding outlet 34, rainwater passing through the water guiding member 30 can flow out of the water guiding member 30 in the left and right directions, thereby avoiding rainwater flowing through the front side of the air inlet 24 and causing the risk of water entering the vehicle.

[0057] According to some embodiments of the utility model, the water trough body 20 is provided with a drain port 25, which is arranged on the lower side of the water guide member 30, so that the water in the water guide trough 31 can smoothly flow into the cavity 21 located on the lower side of the water guide member 30, avoiding water accumulation in the water guide trough 31 and avoiding accumulation of rainwater.

[0058] According to some embodiments of the present invention, the drain port 25 is located at one end of the water trough body 20 in the left-right direction and passes through the bottom wall of the water trough body 20 , and the water guide outlet 34 is formed at one end of the water guide member 30 facing the drain port 25 .

[0059] Reference Figure 3 The drain outlet 25 passes through the bottom wall of the water trough body 20, that is, the drain outlet 25 passes through the lower side plate of the water trough body 20, and the drain outlet 25 is located at the left end or the right end of the lower side plate of the water trough body 20, and is used to discharge the rainwater stored in the water trough body 20 in time, and the water guide outlet 34 is formed at one end of the water guide member 30 facing the drain outlet 25, that is, the water guide outlet 34 is at the same end as the drain outlet 25, so that the rainwater flowing out of the water guide outlet 34 can reach the drain outlet 25 through the shortest path, thereby shortening the drainage time.

[0060] According to some embodiments of the present invention, the two side edges of the water guide member 30 in the front-to-back direction are respectively connected to the front and rear side edges of the open opening 22 of the water flow channel body 20, and the two ends of the water guide member 30 in the left-to-right direction are respectively separated from the left and right side walls of the cavity 21.

[0061] Reference Figure 2 As shown, the front edge of the water guide member 30 is connected to the front edge of the open mouth 22 of the water trough body 20, and the rear edge of the water guide member 30 is connected to the rear edge of the open mouth 22 of the water trough body 20, so that the length of the connection between the water guide member 30 and the water trough body 20 can be increased, and the connection stability can be increased. At the same time, air and rainwater can be prevented from entering the cavity 21 on the front and rear sides of the water guide member 30 through the gap between the two side edges of the water guide member 30 in the front and rear directions and the front and rear side edges of the open mouth 22 of the water trough body 20, thereby preventing air and rainwater from mixing together and flowing to the front side of the air inlet 24, causing water to enter the vehicle.

[0062] Reference Figure 3 As shown, the left end face of the water guiding member 30 is separated from the left side wall face of the cavity 21, and the right end face of the water guiding member 30 is separated from the right side wall face of the cavity 21. External air enters through the grille hole 11, passes through the cavity 21 on the left and right or lower side of the water guiding member 30, and arrives at the cavity 21 located between the front side of the air inlet 24 and the rear side of the water guiding member 30, and finally enters the interior of the vehicle through the air inlet 24. Rainwater flows out through the water guiding outlet 34 and falls into the cavity 21 at the lower part of the water guiding groove 31, thereby realizing rainwater separation.

[0063] According to some embodiments of the utility model, the front and rear edges of the top opening 32 are both provided with a first flange 33, and the front and rear edges of the open mouth 22 are both provided with a second flange 26. The first flange 33 is supported on the upper side of the adjacent second flange 26 and is fixedly connected to the second flange 26.

[0064] Reference Figure 2 As shown, the first flange 33 is located at the front and rear side edges of the top opening 32 of the water guide member 30, and the second flange 26 is located at the front and rear side edges of the open mouth 22 of the water trough body 20. The first flange 33 is located on the upper side of the second flange 26 and is supported on the second flange 26. By setting the first flange 33 to be connected with the second flange 26, the contact surface at the connection between the water trough body 20 and the water guide member 30 can be made larger, which is beneficial to the connection and fixation of the water guide member 30 and the water trough body 20. At the same time, the first flange 33 is connected with the second flange 26, so that the water guide member 30 can be overlapped and positioned on the water trough body 20, thereby making the assembly of the water trough body 20 and the water guide member 30 more convenient.

[0065] When the water guide member 30 is connected to the water trough body 20, preferably, the inside of the water trough body 20 and the water guide member 30 are welded together by means of a boss column. The boss column is a columnar structure used for welding. When in a welding state, the boss column is hot-melted to weld the two workpieces to be welded, that is, when the boss column welding method is adopted, the boss column located on the water trough body 20 or the water guide member 30 can be hot-melted to weld them together.

[0066] According to some embodiments of the present invention, in the up-down direction, the distance between the lower edge of the air inlet 24 and the bottom wall of the cavity 21 is greater than or equal to 60 mm.

[0067] Reference Figure 3 As shown, the distance between the lower edge of the air inlet 24 and the bottom wall of the cavity 21 in the vertical direction must be greater than or equal to 60 mm. For example, this distance can be 61 mm, 62 mm, 63 mm, 64 mm or 65 mm. This distance is the maximum liquid level for storing rainwater. By controlling the distance between the lower edge of the air inlet 24 and the bottom wall of the cavity 21 in the vertical direction, rainwater is prevented from entering the interior of the vehicle through the air inlet 24.

[0068] According to some embodiments of the present invention, the water trough structure 100 further includes an air inlet pipe 40 , which is arranged on the outside of the water trough body 20 and is sealed and connected to the periphery of the air inlet 24 .

[0069] Reference Figure 1-Figure 3 As shown, the air inlet pipe 40 is arranged at the rear side of the water trough body 20 to facilitate connection with the air inlet 24 located at the rear side of the water trough body 20, and is sealed around the periphery to avoid air leakage and energy waste.

[0070] Preferably, the front end of the air inlet duct 40 is connected to the air inlet 24 through a split pin, a first seal 61 is arranged between the front end of the air inlet duct 40 and the periphery of the air inlet 24, the first seal is formed in an annular shape and is a foam seal, the rear end of the air inlet duct is connected to the front panel of the vehicle through a stud, a second seal 62 is arranged between the rear end of the air inlet duct and the front panel of the vehicle, the second seal is formed in an annular shape and is a foam seal. Due to the characteristics of the air inlet duct 40 being stretchable and bendable, the air inlet duct 40 is connected to the front panel, and the water trough body 20 does not need to be directly connected to the front panel, which can make the assembly process simpler and more flexible, and the layout position of the water trough structure 100 is also more flexible.

[0071] According to some embodiments of the present invention, the water trough structure 100 further includes: a drain pipe 50 , the drain pipe 50 is connected to the water trough body 20 , and the inlet end of the drain pipe 50 is connected to the cavity 21 of the water trough body 20 .

[0072] Reference Figure 3 As shown, the drain port 25 of the water trough body 20 passes through the bottom wall of the water trough body 20, and the drain pipe 50 is arranged at the lower side of the water trough body 20, so as to be connected with the drain port 25 located at the lower side of the water trough body 20. Furthermore, the inlet end of the drain pipe is sealed and connected with the periphery of the drain port. For example, a clamp can be used to fasten the drain port 25 to avoid floor leakage at the connection between the drain pipe 50 and the drain port 25, thereby ensuring the safety of the car.

[0073] The vehicle according to the embodiment of the second aspect of the utility model comprises the water flow channel structure 100 according to the embodiment of the first aspect of the utility model.

[0074] According to the vehicle of the embodiment of the utility model, by setting the water trough structure 100 of the first embodiment mentioned above, a water guide member 30 is set in the water trough body 20, and the water guide member 30 is blocked between the grille hole 11 and the air inlet 24, thereby not only allowing air to smoothly enter the air inlet 24, but also preventing rainwater from entering the interior of the vehicle through the air inlet 24, thereby preventing rainwater from entering the automobile air-conditioning system.
