[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0031] First, it should be noted that in the description of the present invention, the terms "upper", "lower", "left", "right", "vertical", "horizontal", "longitudinal", "inner", "outer" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0032] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0033] like Figure 1 As shown, the air inlet of the air-conditioning air-intake box assembly of the existing vehicle air-conditioning is usually arranged upward, and the air-conditioning air-intake grille assembly is arranged above the air-conditioning air-intake box assembly and connected to the front windshield of the vehicle. When the air-conditioning air-intake box assembly is supplying air to the air-conditioning, if the water on the front windshield is sucked into the air-conditioning through the air inlet above the air-conditioning air-intake box assembly, it will cause damage to the air-conditioning.

[0034] To prevent this from happening, Figure 2 As shown, the air-conditioning air-intake grille assembly disposed above the air-conditioning air-intake box assembly is usually provided with a large-sized air-conditioning air-intake grille water guide plate, an air-conditioning air-intake grille drainage pipe, and an air-conditioning air-intake grille air-intake pipe at the lower part of the air-conditioning air-intake grille body, which are used to collect and discharge water flowing from the front windshield and prevent water on the front windshield from entering the air-conditioning air-intake box, so as to ensure the air-water separation of the air-conditioning air-intake box. However, the air-conditioning air-intake grille water guide plate is relatively large in size, and its projected area is equivalent to the area of ​​the air-conditioning air-intake grille body, and it is heavy, has many processing steps, is costly, and requires a large layout space. In addition, the air-conditioning air-intake grille air-intake pipe is composed of multiple components, with a complex structure and high cost.

[0035] like Figure 3 and Figure 4 As shown, the embodiment of the present application provides an air-conditioning air intake grille assembly 10, which includes: a grille body 100 and a water retaining plate 200. The grille body 100 is arranged along the Y-axis direction of the vehicle coordinate system and is set at the front of the vehicle. Figures 6 to 9 As shown, the end of the grille body 100 facing the positive direction of the X axis of the vehicle coordinate system is connected to one end of the front windshield 40 of the vehicle (i.e., the lower end of the front windshield 40). The water retaining plate 200 is arranged on the side of the grille body 100 facing the negative direction of the Z axis of the vehicle coordinate system, and is fixedly connected to the grille body 100.

[0036] When water flows through the outer surface of the front windshield 40 of the vehicle (for example, when the vehicle is driving in the rain), the water will penetrate the connection between the grille body 100 and the lower end of the front windshield 40 of the vehicle (for example, the front windshield adhesive strip groove), flip to the side of the grille body 100 facing the negative Z-axis of the vehicle coordinate system (hereinafter referred to as the inner surface of the grille body 100), and flow along the inner surface of the grille body 100. When the air-conditioning air intake box 30 disposed below the air-conditioning air intake grille assembly 10 is in a working state and provides air for the air conditioner, the water flowing along the inner surface of the grille body 100 will be sucked into the air-conditioning air intake box 30. By providing the water baffle 200, the water penetrating the grille body 100 can be blocked from entering the air-conditioning air intake box 30, and the water can be guided to a set area, thereby avoiding damage to the air-conditioning air intake box 30.

[0037] like Figure 5 and Fig. 9 and Fig.10 As shown, the water retaining plate 200 includes a connecting portion 210 and a water retaining portion 220. The connecting portion 210 of the water retaining plate 200 is connected to the grille body 100, thereby fixing the water retaining plate 200 on the inner surface of the grille body 100. The water retaining portion 220 of the water retaining plate 200 is opposite to the inner surface of the grille body 100.

[0038] In a specific embodiment, the grille body 100 and the water retaining plate 200 are both made of plastic material. Figure 5 and Fig.10 As shown, a positioning rib 110 is provided on the inner surface of the grille body 100, and a positioning hole 211 corresponding to the positioning rib 110 is correspondingly provided on the connecting portion 210 of the water baffle 200. By inserting the positioning rib 110 into the positioning hole 211, the position where the water baffle 200 is fixedly connected to the grille body 100 can be determined. Then, the connection between the positioning rib 110 and the positioning hole 211 is welded by ultrasonic welding, so that the water baffle 200 is fixedly connected to the grille body 100. The embodiment of the present application does not specifically limit the fixed connection method of the grille body 100 and the water baffle 200.

[0039] like Figure 5 and Fig.10 As shown, a guide portion 221 is provided on the surface of the water retaining portion 220 of the water retaining plate 200 opposite to the grille body 100, which is arranged along the Y-axis direction of the vehicle coordinate system and extends toward the grille body 100. The guide portion 221 and the water retaining portion 220 form a guide channel 224. The guide channel 224 forms a drain port 225 at the lower edge of the water retaining portion 220. Figure 5The water flow path shown by the dotted line can prevent the water that penetrates the connection between the grille body 100 and the front windshield 40 from flowing freely by providing the guide portion 221, and collect the water through the guide channel 224 and guide it to the drain port 225 for discharge.

[0040] Furthermore, the guide portion 221 is an arc-shaped structure, so that the guide channel 224 formed by the guide portion 221 and the water retaining portion 220 is also arc-shaped, so as to easily guide the water entering the guide channel 224 to the drain port 225.

[0041] Also like Figure 5 and Fig.10 As shown, a first intercepting portion 222 is further provided on the surface of the water retaining portion 220 opposite to the grille body 100, and the first intercepting portion 222 is arranged along the Y-axis direction of the vehicle coordinate system and extends toward the grille body 100. The first intercepting portion 222 is arranged opposite to the guide portion 221 and is located on the negative side of the guide portion 221 facing the X-axis of the vehicle coordinate system, that is, the first intercepting portion 222 is located closer to the head of the vehicle relative to the guide portion 221.

[0042] like Figure 5 as well as Figures 8 to 10 As shown, on the surface of the grille body 100 opposite to the water retaining portion 220, a second intercepting portion 120 is provided near the connection between the grille body 100 and the front windshield 40, and the second intercepting portion 120 is arranged along the Y-axis direction of the vehicle coordinate system and extends toward the water retaining portion 220. The projection of the second intercepting portion 120 on the XY plane of the vehicle coordinate system is located between the projection of the guide portion 221 and the first intercepting portion 222 on the XY plane.

[0043] like Fig.10, when water flows through the front windshield 40 of the vehicle, penetrates the connection between the grille body 100 and the lower end of the front windshield 40 of the vehicle, turns over to the inner surface of the grille body 100, and flows along the inner surface of the grille body 100; under the action of the second intercepting portion 120, the water flow can be guided to fall downward along the second intercepting portion 120 to the water retaining portion 220 of the water retaining plate 200 located below the grille body 100. By providing the first intercepting portion 222, even when the vehicle is tilted forward, for example, when the vehicle is in a downhill state, the water flow guided to the water retaining portion 220 by the second intercepting portion 120 can be intercepted by the first intercepting portion 222, so that the water flow cannot flow out from the connection between the connection portion 210 of the water retaining plate 200 and the grille body 100, and therefore cannot enter the air intake box 30 from the air intake port 31 of the air intake box 30. By setting the relative position of the second intercepting portion 120 relative to the projections of the guide portion 221 and the first intercepting portion 222 on the XY plane of the vehicle coordinate system as described above, it is ensured that the second intercepting portion 120 guides the water flow to the area between the guide portion 221 and the first intercepting portion 222 on the water retaining portion 220, and finally converges into the guide channel 224 formed by the guide portion 221 and the water retaining portion 220, and finally leaves the air conditioning air inlet grille assembly 10 through the drain port 225.

[0044] like Figure 5 and Fig.11 As shown, a flow blocking portion 223 is provided at the lower edge of the water retaining portion 220, and the flow blocking portion 223 extends in the negative direction of the Z axis of the vehicle coordinate system, that is, extends downward. The flow blocking portion 223 is provided at a position close to the drain outlet 225 on the lower edge of the water retaining portion 220, and is located on the side of the drain outlet 225 close to the XZ plane of the vehicle coordinate system.

[0045] like Figure 5 and Fig.11 As shown, in this embodiment, the guide channel 224 forms two drain ports 225 on both sides of the lower edge of the water retaining portion 220, and a flow blocking portion 223 is provided inside each drain port 225. When the guide channel 224 guides the water flow to the drain port 225 to leave the water retaining plate 200, the flow blocking portion 223 can be used to eliminate the suction force generated by the air-conditioning air intake box 30 that is supplying air to the air conditioner on the water flow flowing out of the drain port 225, thereby preventing the water flow from being sucked into the air conditioner through the air intake port 31 of the air-conditioning air intake box 30 located below the water retaining plate 200.

[0046] like Figures 6 to 8 As shown, an embodiment of the present application further provides an air-conditioning air inlet grille structure, which includes the air-conditioning air inlet grille assembly 10, a water flow channel 20 and an air-conditioning air inlet box 30 as described above.

[0047] like Fig. 9 and Fig.10As shown, the water baffle 200 in the air-conditioning air inlet grille assembly 10 is located above the air inlet 31 of the air-conditioning air inlet box 30, and plays a role in separating air and water.

[0048] The water flow channel 20 is used to guide the water flow discharged from the water outlet 225 of the water shield 200 to a predetermined area, for example, a fender of a vehicle wheel.

[0049] Furthermore, if Figure 5 and Fig.11 As shown, the lower edge of the blocking portion 223 of the water baffle 200 is flush with the upper edge of the air inlet 31 of the air-conditioning air inlet box 30, or the lower edge of the blocking portion 223 of the water baffle 200 is lower than the upper edge of the air inlet 31 of the air-conditioning air inlet box 30, so that the blocking portion 223 is blocked between the air inlet 31 of the air-conditioning air inlet box 30 and the drain outlet 225 of the water baffle 200, preventing the water flowing out of the drain outlet 225 from being sucked into the air inlet 31 of the air-conditioning air inlet box 30.

[0050] The above-mentioned configuration allows the size of the water baffle 200 in the air-conditioning air inlet grille assembly 10 along the Y-axis direction of the vehicle coordinate system to be designed to be as small as possible. The size of the water baffle 200 along the Y-axis direction of the vehicle coordinate system can be equal to or slightly larger than the width of the air inlet 31 of the air-conditioning air inlet box 30 along the Y-axis direction of the vehicle coordinate system. For example, in a specific embodiment, the side of the water baffle 200 only exceeds the side of the air inlet 31 of the air-conditioning air inlet box 30 by 30 mm on one side in the Y-axis direction of the vehicle coordinate system. This size is much smaller than the side of the existing water baffle that exceeds the side of the air inlet of the air conditioner by more than 200 mm, and even the design in which the water baffle and the air-conditioning air inlet grille body have the same width size in the Y-axis direction of the vehicle coordinate system.

[0051] The air-conditioning air-intake grille assembly 10 and the air-conditioning air-intake grille structure provided in the embodiment of the present application achieve the functions of guiding, intercepting and blocking the water flow entering the grille body 100 by arranging the guide portion 221, the first intercepting portion 222 and the blocking portion 223 on the relatively small-sized water baffle plate 200. The problem of water entering the air inlet 31 of the air-conditioning air inlet box 30 when the vehicle is caught in the rain is solved. The embodiment of the present application uses the water baffle plate 200 with a small size, simple structure, low cost and easy installation to achieve the air / water separation function of the air-conditioning air-intake grille that is achieved by the existing large-sized and complex-structured components.

[0052] An embodiment of the present application also provides a vehicle, which includes the air-conditioning air inlet grille structure as described above.

[0053] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
