[0019] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0020] The embodiments of the present application provide a water seepage prevention system for an automobile air-conditioning air inlet and a vehicle, which can solve the problem in the related art that the air intake grille area of ​​the wiper cover is generally small, which is not conducive to air intake of the air conditioner and thus affects the cooling and heating effects of the air conditioner.

[0021] First, as Figure 1 , Figure 2 and Figure 5As shown, an embodiment of the present application provides a water seepage prevention system for an automobile air-conditioning air inlet, comprising: a wiper cover 1, wherein the wiper cover 1 has a plane 110, a slope 19 and a slope 2 18 extending in sequence along the rear of the vehicle body, wherein the slope of the slope 19 is smaller than the slope of the slope 2 18, and the inclination angle of the slope 2 18 is used to be consistent with the inclination angle of the front windshield 2; the plane 110 is provided with an air intake grille 2 12 and an air intake grille 4 14 spaced apart along the width direction of the vehicle body, and the slope 1 19 is provided with an air intake grille 1 11 and an air intake grille 3 13 spaced apart along the width direction of the vehicle body; an automobile air-conditioning air inlet 5, wherein the automobile air-conditioning air inlet 5 is centrally arranged along the width direction of the vehicle body and is located between the air intake grille 2 12 and the air intake grille 4 14 or between the air intake grille 1 11 and the air intake grille 3 13.

[0022] Exemplary, specific reference Figure 5 The wiper cover 1 has a plane 110, a slope 19 and a slope 2 18 extending in sequence along the rear of the vehicle body. The slope 2 18 can be sealed and clamped with the front windshield 2 through the clamping structure 17, and the slope of the slope 2 18 is greater than the slope of the slope 19. The inclination angle of the slope 19 is small, about 7°, which is convenient for water to flow forward and be discharged in time. The automobile air-conditioning air inlet 5 is centered along the width direction of the vehicle body and is located below the wiper cover 1, that is, the automobile air-conditioning air inlet 5 is centered along the width direction of the vehicle body and is located between two air intake grilles spaced apart along the width direction of the vehicle body (located between the air intake grille 1 11 and the air intake grille 3 13 or between the air intake grille 2 12 and the air intake grille 4 14), so that rainwater entering the air intake grille can be discharged from both ends of the automobile air-conditioning air inlet 5 to achieve water vapor separation.

[0023] In combination with the first aspect, in one embodiment, Figure 1 and Figure 2 As shown, the anti-water seepage system of the automobile air-conditioning air inlet also includes: a water dam 15, the water dam 15 is fixed to the wiper cover 1, the air intake grille 2 12 and the air intake grille 4 14 are located in front of the water dam 15 of the vehicle body, and the air intake grille 1 11 and the air intake grille 3 13 are located behind the water dam 15 of the vehicle body.

[0024] Specifically, the inclination angle of the second bevel 18 is consistent with the inclination angle of the front windshield 2 so as to be snap-fitted with the front windshield 2. The inclination angle of the first bevel 19 is smaller to ensure that rainwater is discharged in time. The four air intake grilles provide sufficient air intake for the automobile air-conditioning air inlet 5; two of the air intake grilles (air intake grille 1 11 and air intake grille 3 13) are arranged behind the water retaining dam 15, so as to achieve a beautiful match with the front windshield 2 while increasing the air-conditioning air intake area. When water falls on the wiper cover 1, it can be directly drained through the two air intake grilles (air intake grille 1 11 and air intake grille 3 13) behind the water retaining dam 15. If the water flow is large, the water that crosses the water retaining dam 15 can also be discharged through the two air intake grilles (air intake grille 2 12 and air intake grille 4 14) on the plane 110. The automobile air-conditioning air inlet 5 is located between two air inlet grilles (the front air inlet grille 2 12 and the air inlet grille 4 14 / the rear air inlet grille 11 and the air inlet grille 3 13) along the width direction of the vehicle body. The automobile air-conditioning air inlet 5 and the air inlet grille are staggered in the width direction of the vehicle body. When water vapor enters the air inlet grille, on the way into the automobile air-conditioning air inlet 5, water will separate downward from the gas due to its heavy weight. The longer the air intake path along the width direction of the vehicle body, the more complete the water vapor separation is, thereby preventing the air conditioner from inhaling moisture under humid external conditions.

[0025] In combination with the first aspect, in one embodiment, Figure 2 As shown, the wiper cover 1 is provided with a wiper shaft mounting boss 16 for mounting the wiper.

[0026] In combination with the first aspect, in one embodiment, Figure 5 As shown, the anti-water seepage system of the automobile air-conditioning air inlet also includes: a front windshield water groove sheet metal 3, the front windshield water groove sheet metal 3 is located below the wiper cover 1, the front windshield water groove sheet metal 3 extends along the rear of the vehicle body with a front windshield water groove inclined surface 31, the height of the front windshield water groove inclined surface 31 gradually decreases along the rear of the vehicle body, and the front windshield water groove inclined surface 31 is located below the plane 110, the inclined surface 19 and the inclined surface 2 18.

[0027] Exemplary, specific reference Figure 5 A windshield water channel sheet metal 3 is sealed and fixed at the front lower part of the wiper cover 1. The windshield water channel sheet metal 3 extends along the rear of the vehicle body with a windshield water channel slope 31. The height of the windshield water channel slope 31 gradually decreases along the rear of the vehicle body, and the windshield water channel slope 31 is located below the plane 110, the slope 19 and the slope 2 18. When the windshield 2 and the clamping structure 17 are poorly clamped or aged, the gap in the clamping area increases. When the user washes the car or it rains, water will enter it through the clamping gap. Part of the water drips along the plane 110 onto the windshield water channel slope 31 and is discharged out of the car along the windshield water channel slope 31.

[0028] In combination with the first aspect, in one embodiment, Figure 5 As shown, the lowest part of the windshield water channel slope 31 is connected to a drain pipe 6, and the bottom inner diameter of the drain pipe 6 is flat. The rain drops on the windshield water channel slope 31, and is collected along the windshield water channel slope 31 and connected to the drain pipe 6 at the lowest part of the windshield water channel slope 31 to be discharged out of the vehicle. Since the bottom inner diameter of the drain pipe 6 is flat, the normal discharge of rainwater is ensured on the one hand, and the exhaust gas of the cabin can be prevented from entering the air conditioner on the other hand.

[0029] In combination with the first aspect, in one embodiment, Figure 6 As shown, both ends of the windshield gutter sheet metal 3 along the width direction of the vehicle body are provided with water drop holes 35. Water entering from the air intake grille will fall onto the windshield gutter sheet metal 3, and the water can directly gather along the windshield gutter sheet metal profile to the lowest point of the water drop holes 35, and then be discharged out of the vehicle through the water drop holes 35.

[0030] In combination with the first aspect, in one embodiment, Figure 5 As shown, the anti-seepage system of the automobile air-conditioning air inlet also includes: an air-conditioning air inlet rain shield 4, which is arranged above the automobile air-conditioning air inlet 5, and the air-conditioning air inlet rain shield 4 is extended along the front of the vehicle body, and projected along the height direction of the vehicle body, the air-conditioning air inlet rain shield 4 at least partially overlaps with the inclined surface 19.

[0031] Exemplarily, the air-conditioning air inlet rain shield 4 is arranged above the air-conditioning air inlet 5 of the automobile, and the air-conditioning air inlet rain shield 4 is extended along the front of the vehicle body, and projected along the height direction of the vehicle body, the air-conditioning air inlet rain shield 4 overlaps at least partially with the inclined surface 19. When the front windshield 2 and the wiper cover 1 are aged or poorly connected, rainwater will enter between the front windshield 2 and the wiper cover 1, and slide down along the inclined surface 2 18. Because there is an inclination angle difference between the inclined surface 2 18 and the inclined surface 1 19, most of the rainwater drips at the corner of the inclined surface 2 18 and the inclined surface 1 19, and then falls into the air-conditioning air inlet rain shield 4, and a small amount of rainwater drips along the lowest point of the inclined surface 19 and is discharged through the front windshield water channel sheet metal 3.

[0032] In combination with the first aspect, in one embodiment, Figure 4 and Figure 5 As shown, along the width direction of the vehicle body, the length of the air-conditioning air inlet rain shield 4 is at least greater than the length of the automobile air-conditioning air inlet 5; the air-conditioning air inlet rain shield 4 has a rain shield slope 1 41, a rain shield slope 2 42 and a rain shield end vertical surface 44 extending in sequence along the front of the vehicle body, and the height of the rain shield slope 1 41 gradually decreases along the front of the vehicle body.

[0033] Exemplarily, rainwater falling on the rain shield slope 1 41 flows toward the rain shield slope 2 42 and is blocked by the rain shield end vertical surface 44 to be gathered along the width direction of the vehicle body. Because the length of the air-conditioning air inlet rain shield 4 is at least greater than the length of the automobile air-conditioning air inlet 5, the gathered rainwater will be discharged from both ends of the air-conditioning air inlet rain shield 4, reducing the probability of water flowing forward and entering the automobile air-conditioning air inlet 5.

[0034] In combination with the first aspect, in one embodiment, Figure 4 and Figure 5 As shown, along the width direction of the vehicle body, both ends of the rain shield end vertical surface 44 are fixed with rain shield side vertical surfaces 45, and the rain shield side vertical surfaces 45 are used to discharge rainwater to the rear of the vehicle body.

[0035] Exemplarily, rain shield side facades 45 are fixed at both ends of the rain shield end facade 44, so that the collected rainwater can be discharged along the rain shield side facades 45 along the rear of the vehicle body, further reducing the probability of water flowing forward and entering the vehicle air conditioning air inlet 5.

[0036] In combination with the first aspect, in one embodiment, Figure 3 and Figure 5 As shown, the top surface of the air-conditioning air inlet rain shield 4 is arched, which is used to discharge rainwater in the width direction of the vehicle body. For example, the top surface of the air-conditioning air inlet rain shield 4 is arched, and the middle height of the air-conditioning air inlet rain shield 4 gradually decreases along the two ends of itself, which can improve the drainage efficiency of the collected rainwater and prevent the problem that insufficient drainage capacity causes rainwater to overflow the end elevation 44 of the rain shield and flow to the front of the automobile air-conditioning air inlet 5 and splash into the automobile air-conditioning air inlet 5.

[0037] In combination with the first aspect, in one embodiment, Figure 4 and Figure 5 As shown, the anti-water seepage system of the automobile air-conditioning air inlet further includes: a front windshield lower edge sheet metal part 9, the front windshield lower edge sheet metal part 9 is used to be arranged between the front windshield 2 and the automobile air-conditioning air inlet 5; a sealing foam 47 is arranged between the air-conditioning air inlet rain shield 4 and the front windshield lower edge sheet metal part 9. Exemplarily, a sealing foam 47 is arranged between the air-conditioning air inlet rain shield 4 and the front windshield lower edge sheet metal part 9, which effectively prevents water from entering the gap between the air-conditioning air inlet rain shield 4 and the front windshield lower edge sheet metal part 9 along the side wall of the front windshield lower edge sheet metal part 9 and entering the automobile air-conditioning air inlet 5.

[0038] In combination with the first aspect, in one embodiment, Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, the rear end of the air-conditioning air inlet rain shield 4 is extended with a rain shield mounting vertical surface 48 along the vehicle body height direction, and both ends of the air-conditioning air inlet rain shield 4 along the vehicle body width direction are extended to a rain shield mounting plane 46; the anti-water seepage system of the automobile air-conditioning air inlet also includes: a front windshield water groove sheet metal 3, and the front windshield water groove sheet metal 3 is located below the wiper cover 1; the front windshield water groove sheet metal 3 is fixed with a sealing buckle 8, and the rain shield mounting plane 46 is provided with screws, and the screws are threadedly connected in the sealing buckle 8; the rain shield mounting vertical surface 48 and the front windshield bottom edge sheet metal 9 are sealed and fixed by welding studs and nuts.

[0039] Exemplarily, the rain shield mounting elevation 48 is sealed and fixed to the sheet metal part 9 at the lower edge of the front windshield, and the sealing and fixing method can be a connection method of welding studs and nuts, which can avoid water leakage from the sheet metal opening; both ends of the air-conditioning air inlet rain shield 4 along the width direction of the vehicle body extend to a rain shield mounting plane 46, and the rain shield mounting plane 46 is sealed and fixed to the front windshield water groove sheet metal 3, and the two sides of the air-conditioning air inlet rain shield 4 are connected to the front windshield water groove sheet metal 3 by sealing buckles 8 and screws 7. The sealing buckle 8 is clamped on the opening of the front windshield water groove sheet metal 3, and is sealed with the front windshield water groove sheet metal 3 by soft glue to avoid water leakage and prevent exhaust gas from entering; further, a sealing foam 47 can be added between the mounting surface of the air-conditioning air inlet rain shield 4 and the front windshield water groove sheet metal 3 for sealing.

[0040] In combination with the first aspect, in one embodiment, Figure 4 As shown, the height of the rain shield installation plane 46 is lower than the rain shield slope 1 41 and the rain shield slope 2 42, that is, the height difference between the rain shield installation plane 46 and the rain shield slope 1 41 and the rain shield slope 2 42 is extended to form the rain shield side slope 43, which prevents rainwater from directly dripping into the automobile air inlet 5 of the air conditioner, and facilitates some rainwater to slide directly from the rain shield side slope 43 into the air inlet of the air conditioner The two ends of the rain shield 4 are discharged.

[0041] In combination with the first aspect, in one embodiment, Figure 5 As shown, the windshield water channel sheet metal 3 includes a windshield water channel inclined surface 31, a front windshield water channel plane 32 and a front windshield water channel mounting surface 1 33. The windshield water channel sheet metal 3 is sealed with the front lower part of the wiper cover 1 through the windshield water channel mounting surface 1 33. The sealing portion can be sealed with a sealing foam 2 34 to prevent the exhaust gas in the cabin from entering. The windshield water channel mounting surface 1 33 extends along the rear and lower part of the vehicle body to form the windshield water channel inclined surface 31, which is convenient for rainwater to slide along the windshield water channel inclined surface 31 into the drain pipe 6 of the front windshield water channel plane 32 for discharge. The rear end of the front windshield water channel plane 32 is fixed to the lower end of the automobile air inlet 5 through another sheet metal part.

[0042] Second, as Figure 1 , Figure 2 and Figure 5 As shown, an embodiment of the present application provides a vehicle, which includes: a wiper cover 1, wherein the wiper cover 1 has a plane 110, a slope 19 and a slope 2 18 extending in sequence along the rear of the vehicle body, the slope of the slope 19 is smaller than the slope of the slope 2 18, and the inclination angle of the slope 2 18 is used to be consistent with the inclination angle of the front windshield 2; the plane 110 is provided with an air intake grille 2 12 and an air intake grille 4 14 spaced apart along the width direction of the vehicle body, and the slope 1 19 is provided with an air intake grille 1 11 and an air intake grille 3 13 spaced apart along the width direction of the vehicle body; and an automobile air-conditioning air inlet 5, wherein the automobile air-conditioning air inlet 5 is centrally arranged along the width direction of the vehicle body and is located between the air intake grille 2 12 and the air intake grille 4 14 or between the air intake grille 1 11 and the air intake grille 3 13.

[0043] Exemplary, specific reference Figure 5 The wiper cover 1 has a plane 110, a slope 19 and a slope 2 18 extending in sequence along the rear of the vehicle body. The slope 2 18 can be sealed and clamped with the front windshield 2 through the clamping structure 17, and the slope of the slope 2 18 is greater than the slope of the slope 19. The inclination angle of the slope 19 is small, about 7°, which is convenient for water to flow forward and be discharged in time. The automobile air-conditioning air inlet 5 is centered along the width direction of the vehicle body and is located below the wiper cover 1, that is, the automobile air-conditioning air inlet 5 is centered along the width direction of the vehicle body and is located between two air intake grilles spaced apart along the width direction of the vehicle body (located between the air intake grille 1 11 and the air intake grille 3 13 or between the air intake grille 2 12 and the air intake grille 4 14), so that rainwater entering the air intake grille can be discharged from both ends of the automobile air-conditioning air inlet 5 to achieve water vapor separation.

[0044] In conjunction with the second aspect, in one implementation, Figure 1 and Figure 2 As shown, the anti-water seepage system of the automobile air-conditioning air inlet also includes: a water dam 15, the water dam 15 is fixed to the wiper cover 1, the air intake grille 2 12 and the air intake grille 4 14 are located in front of the water dam 15 of the vehicle body, and the air intake grille 1 11 and the air intake grille 3 13 are located behind the water dam 15 of the vehicle body.

[0045] Specifically, the inclination angle of the second bevel 18 is consistent with the inclination angle of the front windshield 2 so as to be snap-fitted with the front windshield 2. The inclination angle of the first bevel 19 is smaller to ensure that rainwater is discharged in time. The four air intake grilles provide sufficient air intake for the automobile air-conditioning air inlet 5; two of the air intake grilles (air intake grille 1 11 and air intake grille 3 13) are arranged behind the water retaining dam 15, so as to achieve a beautiful match with the front windshield 2 while increasing the air-conditioning air intake area. When water falls on the wiper cover 1, it can be directly drained through the two air intake grilles (air intake grille 1 11 and air intake grille 3 13) behind the water retaining dam 15. If the water flow is large, the water that crosses the water retaining dam 15 can also be discharged through the two air intake grilles (air intake grille 2 12 and air intake grille 4 14) on the plane 110. The automobile air-conditioning air inlet 5 is located between two air inlet grilles (the front air inlet grille 2 12 and the air inlet grille 4 14 / the rear air inlet grille 11 and the air inlet grille 3 13) along the width direction of the vehicle body. The automobile air-conditioning air inlet 5 and the air inlet grille are staggered in the width direction of the vehicle body. When water vapor enters the air inlet grille, on the way into the automobile air-conditioning air inlet 5, water will separate downward from the gas due to its heavy weight. The longer the air intake path along the width direction of the vehicle body, the more complete the water vapor separation is, thereby preventing the air conditioner from inhaling moisture under humid external conditions.

[0046] In conjunction with the second aspect, in one implementation, Figure 2 As shown, the wiper cover 1 is provided with a wiper shaft mounting boss 16 for mounting the wiper.

[0047] In conjunction with the second aspect, in one implementation, Figure 5 As shown, the anti-water seepage system of the automobile air-conditioning air inlet also includes: a front windshield water groove sheet metal 3, the front windshield water groove sheet metal 3 is located below the wiper cover 1, the front windshield water groove sheet metal 3 extends along the rear of the vehicle body with a front windshield water groove inclined surface 31, the height of the front windshield water groove inclined surface 31 gradually decreases along the rear of the vehicle body, and the front windshield water groove inclined surface 31 is located below the plane 110, the inclined surface 19 and the inclined surface 2 18.

[0048] Exemplary, specific reference Figure 5 A windshield water channel sheet metal 3 is sealed and fixed at the front lower part of the wiper cover 1.
