Description

Ventilation cover, front cabin drainage and air intake system and vehicle

[0001] This application claims priority to Chinese patent application No. 202311652572.3 filed on December 4, 2023, entitled “Ventilation cover, front cabin drainage and air intake system and vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of automobile technology, and in particular to a ventilation cover, a front cabin drainage and air intake system, and a vehicle. Background Art

[0003] The front cabin drainage and air intake system is an important part of the front of the car. It is generally arranged between the front windshield and the engine hood of the car. On the one hand, it is used to provide sufficient air intake for the vehicle's air-conditioning system to meet the air circulation needs of the passenger compartment. On the other hand, it plays a drainage role, guiding the water that falls on the roof and front windshield of the car to be discharged outside the car.

[0004] The front cabin drainage and air intake system primarily consists of a ventilation cover and a water gutter. The ventilation cover is typically equipped with a drain port connected to the gutter and an air intake port connected to the air conditioning system. Water from the car's windshield and roof that falls onto the ventilation cover typically flows through the drain port into the gutter and ultimately out of the vehicle. In related art, to prevent water that falls onto the ventilation cover from entering the air conditioning system and passenger compartment through the air intake, the air intake opening is typically designed to be relatively small. However, this can negatively impact the air intake performance of the air conditioner.

[0005] Summary of the Invention

[0006] This application provides a ventilation cover, a front cabin drainage and air intake system, and a vehicle. The ventilation cover can prevent water from entering the air intake while increasing the air intake volume of the air intake, thereby improving the air intake performance of the vehicle's air conditioning system. The technical solution is as follows:

[0007] In a first aspect, the present application provides a ventilation cover, the ventilation cover comprising a main body and a retaining portion; the main body is provided with an opening and a first drain port at intervals; the bottom end of the retaining portion is disposed around the opening and is connected to the main body; the top end of the retaining portion forms an air inlet, the air inlet being in communication with the opening so as to provide external air to a vehicle's air conditioning system through the opening, the bottom end and the top end being opposite each other;

[0008] Wherein, a plane where at least a portion of the air inlet is located is inclined relative to a plane where the opening is located.

[0009] In the solution shown in the present application, a blocking portion is provided around the opening on the main body of the ventilation cover, and the top of the blocking portion forms an air inlet. Since the plane where at least a part of the air inlet is located is inclined relative to the plane where the opening is located, the opening area corresponding to the air inlet is larger than the opening area of ​​the opening on the main body.

[0010] Since a larger opening area means a larger air intake area, compared with the solution in the related art that directly uses the opening on the main body as the air intake, the solution shown in this application can increase the air intake volume of the air intake and improve the air intake performance of the vehicle's air-conditioning system.

[0011] Moreover, since the enclosure portion is arranged around the opening on the main body, the air inlet formed by the top of the enclosure portion is higher than the surface of the main body, that is, water flowing on the main body is not easy to pass over the enclosure portion and enter the air inlet, thereby avoiding the phenomenon of water entering the air inlet.

[0012] In a possible implementation, the height of the front end of the enclosure portion is lower than the height of the rear end of the enclosure portion, the front end and the rear end are opposite to each other, and the front end is farther away from the front windshield of the vehicle than the rear end.

[0013] In the solution presented in this application, water flowing down from the vehicle's roof and windshield flows sequentially through the rear and front ends of the enclosure. Therefore, the rear end of the enclosure typically encounters a relatively larger amount of water than the front end. By making the rear end of the enclosure higher than the front end, the rear end's water-blocking effect is enhanced, effectively preventing water on the main body from flowing over the rear end of the enclosure and into the air inlet.

[0014] Furthermore, when the front and rear ends of the enclosure portion have different heights, at least a portion of the air inlet formed by the top end of the enclosure portion will be inclined relative to the opening, thereby increasing the air inlet area.

[0015] In a possible implementation, the height of the enclosure portion gradually increases from the front end of the enclosure portion to the rear end of the enclosure portion.

[0016] In one possible implementation, the ventilation cover further includes a mesh portion, which covers the air inlet and is connected to the top end of the enclosure portion; wherein the main body portion, the enclosure portion and the mesh portion are an integrally formed structure.

[0017] In the solution presented in this application, a mesh portion is also provided at the air inlet to prevent foreign matter from entering the air conditioning system through the air inlet opening, thereby protecting the air conditioning system. By integrating the main body, enclosure, and mesh portion into an integrated molding process, the manufacturing process of the ventilation cover is simplified while also improving the structural strength of the ventilation cover.

[0018] In one possible implementation, the vent cover further includes a first dam, the first dam being connected to the main body and separating the main body into a first portion and a second portion isolated from each other, the opening and the enclosure being both located in the first portion, and the first drain opening being located in the second portion;

[0019] At least one end of the first dam is located at a side edge of the main body and is spaced apart from a rear edge of the main body, wherein the side edges are edges of the main body located on both sides, and the rear edge is an edge of the main body close to the front windshield of the vehicle.

[0020] In the solution presented in this application, a first dam is connected to the main body. At least one end of the first dam extends to a side edge of the main body, thereby separating the main body into a first and second isolated sections. The air intake is located in the first section, and the first drain is located in the second section. Water flowing down the vehicle's windshield first flows into the second section, where it is intercepted by the first dam and retained before being discharged through the first drain. Therefore, water is less likely to flow into the first section, further ensuring that water does not enter the air intake.

[0021] In a possible implementation, the first dam traverses the main body along the length direction of the main body, and the two ends of the first dam are respectively located at the two side edges of the main body;

[0022] The first retaining dam comprises a first dam section, a second dam section, and a third dam section sequentially connected along the length direction, the second dam section extends along the length direction, and at least a portion of the first dam section and at least a portion of the third dam section extend along the width direction of the main body;

[0023] There are at least two first drainage outlets, at least two of which are connected to the second dam section and are located close to the first dam section and the third dam section respectively, and there is a gap between each first drainage outlet and the adjacent first dam section or the third dam section.

[0024] In the solution presented in this application, a first dam extends transversely along the length of the main body, with its ends located at the two side edges of the main body. The first, second, and third dam sections of the first dam are sequentially connected, with the second dam section extending along the length, and the first and third dam sections both extending along the width, forming a semi-enclosed structure. A first drain outlet connects to the second dam section. When water flows into the second section, some of the water flows directly into the first drain outlet or, intercepted by the second dam section, flows back into the first drain outlet. The remaining water flows toward the side edges of the main body and, intercepted by the first and third dam sections, flows back into the first drain outlet. Therefore, the first dam has a good overall water-retaining effect and promotes drainage. Compared to solutions in the related art that allow water to flow out of the side edges of the main body, the drainage distance is shortened, and drainage efficiency is increased.

[0025] In addition, since at least two first drainage outlets are respectively arranged close to the first dam section and the third dam section, the water can be smoothly discharged regardless of the posture of the vehicle body.

[0026] In a possible implementation, the ventilating cover further includes two second dams, both of which are located in the second portion and are respectively erected at the two side edges of the main body;

[0027] The dam surface of each second dam is connected to the end of the adjacent first dam, and the end of the second dam extends to the rear edge of the main body in a direction away from the first dam, and the end is the end of the second dam close to the front windshield of the vehicle; wherein the height of the second dam is less than the height of the end of the first dam to which it is connected.

[0028] The solution shown in the present application further strengthens the enclosing effect on the second part by respectively setting two second dams at the two side edges of the main body, and the end of the first dam is connected to the dam surface of the second dam, which can to a certain extent suppress the water falling into the second part from overflowing from the side edges of the main body, and promote the water to be discharged from the first drain outlet as much as possible.

[0029] Furthermore, since the height of the second dam is less than the height of the end of the first dam to which it is connected, when the amount of water on the main body is relatively large and the drainage capacity of the first drain outlet is insufficient, the water in the second part can also be discharged over the second dam to relieve the drainage pressure, thereby ensuring that the water in the second part will not cross the first dam which is relatively higher and cause the risk of water entering the air inlet.

[0030] In one possible implementation, the ventilation cover further includes two extended water guides, which are respectively connected to the ends of the two second dams and are used to guide water that has passed over the second dams to the area between the fender and the shock absorber tower of the vehicle for discharge.

[0031] In one possible implementation, at least two second drain outlets are further provided on the main body portion, and the at least two second drain outlets are located in the first part and are respectively located on opposite sides of the enclosure portion in the length direction, and there is a gap between the second drain outlets and the enclosure portion.

[0032] The solution presented in this application features at least two secondary drain ports within the first section. This ensures that even if water in the second section overflows the first barrier and flows into the first section, it can be promptly drained through the secondary drain ports, preventing water from accumulating in the first section and flowing into the air intake. Furthermore, because the at least two secondary drain ports are located on opposite sides of the barrier in the longitudinal direction, water can be drained smoothly regardless of the vehicle's posture, effectively maintaining the drainage effect of the first section.

[0033] In a possible implementation, the height of the main body gradually decreases from the middle to both sides; and the at least two second drain outlets are respectively located at the lowest positions at both ends of the main body in the first part.

[0034] The solution shown in the present application designs the main body to be a structure with a height gradually decreasing from the middle to the two sides, and the second drain outlet is set at the lowest position of the main body in the first part. In this way, water flowing into the first part will naturally flow to the second drain outlets located on both sides under the action of gravity and be discharged, avoiding the formation of water accumulation in the first part and ensuring the drainage effect.

[0035] In one possible implementation, the ventilation cover further includes a stop portion, which is connected to the front edge of the main body away from the front windshield of the vehicle and is used for installing a sealing strip; wherein a first gap is provided between the stop portion and the enclosure portion.

[0036] In the solution shown in the present application, a stop portion is connected to the front edge of the main body, and a first gap is provided between the stop portion and the enclosure portion. The first gap is used to guide and drain water, and can prevent water flowing into the first part from accumulating at the stop portion, thereby preventing the accumulated water from flowing over the front end of the enclosure portion and flowing into the air inlet.

[0037] In a possible implementation manner, there is a second gap between the first dam and the surrounding portion.

[0038] In the solution shown in the present application, there is a second gap between the first dam and the enclosure portion to prevent water that has passed over the first dam from directly falling onto the top of the enclosure portion and then flowing into the air inlet.

[0039] In a possible implementation, the ventilation cover further includes a brim portion, which is located above the air inlet and connected to the first dam.

[0040] The solution shown in the present application is provided with a brim portion above the air inlet. On the one hand, the brim portion can prevent liquid water that has passed the first dam from flowing directly into the air inlet. On the other hand, it can prevent water mist that has passed the first dam from being sucked into the air inlet by the negative pressure of the air-conditioning system, thereby further improving the effect of preventing water from entering the air inlet.

[0041] In a second aspect, the present application provides a front cabin drainage and air intake system, the system comprising an air guide member, a drainage member, and the ventilation cover plate described in the first aspect;

[0042] The air guide member and the drainage member are both located below the ventilation cover plate, wherein the air guide member is connected to the opening on the ventilation cover plate, and the drainage member is connected to the first drainage port on the ventilation cover plate.

[0043] In the solution shown in the present application, the front cabin drainage and air intake system performs the air intake function through the opening on the ventilation cover and the air guide member, and performs the drainage function through the first drainage port and the drainage member on the ventilation cover.

[0044] In a possible implementation, one end of the drainage member away from the first drainage port extends toward the bottom guard plate of the vehicle, so as to guide water flowing into the first drainage port to which it is connected to the bottom guard plate.

[0045] In the solution shown in the present application, the water discharged through the first drain port will flow to the bottom guard plate of the vehicle under the guidance of the drain member, and will be discharged outside the vehicle through the openings on the bottom guard plate.

[0046] In one possible implementation, the air guide is an air guide pipe, and the air guide pipe includes a first pipe section and a second pipe section, wherein one end of the first pipe section is connected to the opening, and the other end is connected to the second pipe section;

[0047] The second pipe segment is bent relative to the first pipe segment, and the angle between the first pipe segment and the second pipe segment is less than 90 degrees.

[0048] In the solution shown in the present application, the air guide member includes a first pipe section connected to the opening on the main body, and a second pipe section connected to the first pipe section by a bend. The angle between the first pipe section and the second pipe section is an acute angle, less than 90 degrees, so that water droplets attached to the inner walls of the first pipe section and the second pipe section can drip naturally under the action of gravity without entering the air-conditioning system along the inner wall of the second pipe section.

[0049] In a possible implementation, a third drain outlet is provided on the air guide member, and the third drain outlet is located at the connection between the first pipe segment and the second pipe segment.

[0050] In the solution shown in the present application, a third drain outlet is provided at the connection between the first pipe section and the second pipe section of the air guide member, so that even if a small amount of water enters the air guide member, it can be discharged from the third drain outlet in time, thereby preventing water accumulation in the air guide duct.

[0051] In a third aspect, the present application provides a vehicle, comprising the ventilation cover described in the first aspect, or comprising the front cabin drainage and air intake system described in the second aspect.

[0052] In the solution presented in this application, a retaining member surrounds the opening on the main body of the vent cover, with the top of the retaining member forming an air inlet. Because the plane of at least a portion of the air inlet is inclined relative to the plane of the opening, the corresponding opening area of ​​the air inlet is larger than that of the opening on the main body. Because a larger opening area means a larger air intake area, compared to related art solutions that directly use the opening on the main body as the air inlet, the solution presented in this application can increase the air intake volume of the air inlet, thereby improving the air intake performance of the vehicle's air conditioning system.

[0053] Moreover, since the enclosure portion is arranged around the opening on the main body portion, the air inlet formed by the top of the enclosure portion is higher than the surface of the main body portion, that is, water flowing on the main body portion is not easy to pass over the enclosure portion and enter the air inlet, thereby avoiding the phenomenon of water entering the air inlet, protecting the air-conditioning system, and preventing water from entering the passenger compartment of the vehicle, thereby improving the environmental comfort and driving experience.

[0075] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0076] This embodiment relates to a ventilation cover panel. The air inlet on the ventilation cover panel has a relatively large air intake area, thereby helping to increase the air intake volume, thereby improving the air intake performance of the air conditioning system. Furthermore, the ventilation cover panel can effectively prevent water from entering the air inlet, thereby preventing water from entering the air conditioning system and passenger compartment, thereby enhancing the protection of the air conditioning system and improving the environmental comfort of the passenger compartment.

[0077] Among them, the ventilation cover can be applied to the front cabin drainage and air intake system of the vehicle, so that the ventilation cover can cooperate with the air duct on the one hand to provide a larger amount of external air for the vehicle's air-conditioning system to realize the air intake function; on the other hand, it can cooperate with the drainage parts to quickly discharge the water flowing down from the roof and front windshield of the vehicle to the outside of the vehicle to realize the drainage function.

[0078] Next, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

[0079] Figure 1 is a schematic diagram of the structure of a ventilation cover 1 provided in an embodiment of the present application. Referring to Figure 1 , the ventilation cover 1 provided in an embodiment of the present application includes a main body 11 and an enclosure 12. The main body 11 is used to constitute the main structure of the ventilation cover 1. Corresponding to the air intake and drainage functions of the ventilation cover 1, the main body 11 is provided with an opening 111 and a first drainage port 112, respectively, and the opening 111 and the first drainage port 112 are spaced apart from each other. The enclosure 12 is connected to the main body 11, with its bottom end 121 surrounding the opening 111 and vertically connected to the main body 11. The top end 122 of the enclosure 12 forms an air inlet 123, which communicates with the opening 111 and is located above it. That is, the air inlet 123 is higher than the opening 111 and higher than the surface of the main body 11 used to define the opening 111. External air can flow into the opening 111 through the air inlet 123 under negative pressure, and then into the vehicle's air conditioning system. The top end 122 and bottom end 121 of the enclosure 12 are positioned opposite each other.

[0080] In this embodiment, the plane where at least a portion of the air inlet 123 is located is inclined relative to the plane where the opening 111 is located, that is, the height difference between different positions of the air inlet 123 and the corresponding positions of the opening 111 is not completely equal. There may be a position with a relatively larger height difference, and at this time the distance between the air inlet 123 at this position and the opening 111 is relatively farther; there may also be a position with a relatively smaller height difference, and at this time the distance between the air inlet 123 at this position and the opening 111 is relatively closer.

[0081] When the vent cover 1 receives water flowing down from the top of the vehicle and the front windshield 4, the water flows from the rear to the front of the vehicle body, where the rear to the front refers to the flow from the rear end to the front end. Therefore, considering that the amount of water faced by the rear end 125 of the enclosure 12 is generally greater than the amount of water faced by the front end 124 of the enclosure 12, in one example, as shown in FIG2 , the height of the front end 124 of the enclosure 12 is lower than the height of the rear end 125 of the enclosure 12, that is, the front end 124 of the enclosure 12 is closer to the opening 111 than the rear end 125. The front end 124 and the rear end 125 of the enclosure 12 are opposite to each other, and the front end 124 is farther away from the front windshield 4 of the vehicle than the rear end 125.

[0082] Therefore, on the one hand, the rear end 125 of the enclosure portion 12 has a better water-blocking effect due to its higher height, which can effectively prevent water flowing onto the main body 11 from flowing over the rear end 125 and entering the air inlet 123; on the other hand, due to the structural design of low front and high back, the top end 122 of the enclosure portion 12 can form an air inlet 123 that is tilted higher at least in part from the front end 124 to the rear end 125.

[0083] For example, as shown in Figure 2, the height of the enclosure portion 12 gradually increases from the front end 124 of the enclosure portion 12 to the rear end 125 of the enclosure portion 12, so the air inlet 123 is in the shape of a slope and is located in a plane as a whole, and the plane is inclined relative to the plane where the opening 111 is located.

[0084] For another example, along the direction from the front end 124 of the enclosure 12 to the rear end 125 of the enclosure 12, the height of the front half of the enclosure 12 gradually increases, while the height of the rear half remains unchanged. Therefore, the front half of the air inlet 123 is inclined and located in a plane, which is parallel to the plane where the opening 111 is located, and the rear half is located in another plane, which is parallel to the plane where the opening 111 is located.

[0085] The height of each position of the enclosure 12 can be configured by the designer according to actual needs, but it should be ensured that the height is not too low, otherwise the water flow on the main body 11 will easily pass over the enclosure 12 and enter the air inlet 123; at the same time, the height cannot be too high, otherwise the top end 122 of the enclosure 12 will be against the front hood (also called the engine hood), hindering the air intake.

[0086] For example, the height of the front end 124 of the enclosure portion 12 may be in the range of 20-30 mm, and the height of the rear end 125 of the enclosure portion 12 may be in the range of 30-40 mm.

[0087] In one example, as shown in FIG3 and FIG4 , the ventilation cover 1 may further include a mesh portion 13 , which may cover the air inlet 123 and be connected to the top end 122 of the enclosure portion 12 to prevent debris from entering the air inlet 123 .

[0088] The mesh portion 13 and the enclosure portion 12 may be formed separately and then connected together by bonding, welding, clamping, or the like.

[0089] Alternatively, the mesh portion 13 and the enclosure portion 12 can be an integrally formed air intake grille with a frame, the frame of which surrounds the opening 111 of the main body 11 and is sealed to the main body 11 by bonding, welding, etc., to form the enclosure portion 12.

[0090] Alternatively, the mesh portion 13, the enclosure portion 12 and the body portion 11 may be an integrally formed structure manufactured through an integral molding process. Compared to the aforementioned two solutions, this integrally formed structure has a relatively simple manufacturing process and the resulting ventilation cover 1 has better structural strength.

[0091] Continuing with FIG3 , the ventilated cover 1 provided in the embodiment of the present application may further include a first dam 14 , which is connected to the main body 11 and divides the main body 11 into a first portion 113 and a second portion 114 . The space within the first portion 113 constitutes a dry area, where water cannot easily flow in. The opening 111 and the enclosure 12 are both located in the first portion 113 . The space within the second portion 114 constitutes a wet area, primarily serving to receive and drain water. The first drain port 112 is located in the second portion 114 . It should be noted that the first portion 113 and the second portion 114 are isolated from each other and are not connected to each other.

[0092] In this embodiment, in order to make the first dam 14 have a better water-retaining effect and more effectively prevent the water flowing into the second part 114 from flowing over the first dam 14 and into the first part 113, the height of the first dam 14 is set to be higher than the height of the enclosure 12, but the height of the first dam 14 cannot be too high to avoid affecting the gas circulation and thus affecting the air intake of the air inlet 123.

[0093] Optionally, the height range of the first dam 14 can be 40-50 mm, and its specific height is configured by the designer according to actual needs, such as 42 mm, 44 mm or 46 mm. The embodiment of the present application does not make specific limitations on this, as long as the height of the first dam 14 is higher than the height of the enclosure 12 and there is a gap between it and the front hood.

[0094] It will be readily understood that the first dam 14 has two ends 144 that oppose each other in the direction of extension. In one example, as shown in Figures 3 and 5 , at least one of the two ends 144 of the first dam 14 is located at the side edge 118 of the main body 11 and is spaced apart from the rear edge 116 of the main body 11. This allows the enclosed first portion 113 and second portion 114 to have different spatial positions and arrangements. In this embodiment, the side edges 118 of the main body 11 are the edges located on both sides, while the rear edge 116 of the main body 11 is the edge proximal to the vehicle's front windshield 4.

[0095] Figure 3 illustrates a first dam 14 with two end portions 144 located at the two side edges 118 of the main body 11. In this embodiment, referring to Figures 2 and 3, the first dam 14 extends across the main body 11 along its length, with the first portion 113 and the second portion 114 arranged sequentially from front to back. When used in a vehicle, the first portion 113 is entirely located beneath the vehicle's hood to prevent rainwater from directly entering the air intake 123 during rainy weather. The second portion 114 abuts the vehicle's front windshield 4, and the hood at most covers the area of ​​the second portion 114 proximal to the first portion 113, allowing the second portion 114 to receive and drain rainwater.

[0096] Continuing with Figure 3 , the first retaining dam 14 includes a first dam section 141, a second dam section 142, and a third dam section 143, which are sequentially connected along the length direction. The second dam section 142 extends along the length direction, and the first dam section 141 and the third dam section 143 are located on the same side of the second dam section 142. Furthermore, at least a portion of the first dam section 141 and at least a portion of the third dam section 143 extend along the width direction of the main body 11. As a result, the first retaining dam 14 has a semi-enclosed structure that can collect water flowing into the second area, facilitating its outflow from the first drain outlet 112. In Figure 3 , the length direction of the main body 11 is indicated as the X direction, and the width direction is indicated as the Y direction.

[0097] Optionally, the length of the second dam section 142 is greater than the length of the first dam section 141 , and greater than the length of the third dam section 143 .

[0098] Optionally, the length of the second dam section 142 is greater than the sum of the length of the first dam section 141 and the length of the third dam section 143 .

[0099] There are at least two first drainage outlets 112, and at least two first drainage outlets 112 are connected to the second dam section 142 and are located near the first dam section 141 and the third dam section 143, respectively. Each of the first drainage outlets 112 is spaced apart from the adjacent first dam section 141 or third dam section 143. The fact that at least two first drainage outlets 112 are located near the first dam section 141 and the third dam section 143, respectively, and are spaced apart from the adjacent first dam section 141 or third dam section 143, means that for any first drainage outlet 112, there is a relatively smaller space between it and the adjacent first dam section 141 or third dam section 143, and a relatively larger space between it and the distant first dam section 141 or third dam section 143.

[0100] Optionally, the distance between the two first drain outlets 112 is greater than the distance between the first dam section 141 and the adjacent first drain outlet 112 , and greater than the distance between the third dam section 143 and the adjacent first drain outlet 112 .

[0101] Exemplarily, as shown in Figure 3, there are two first drain outlets 112, and both of these first drain outlets 112 are connected to the second dam section 142. One of the first drain outlets 112 is arranged close to the first dam section 141, and has a relatively smaller interval between it and the first dam section 141, and a relatively larger interval between it and the third dam section 143; the other first drain outlet 112 is arranged close to the third dam section 143, and has a relatively smaller interval between it and the third dam section 143, and a relatively larger interval between it and the first dam section 141. In this way, on the one hand, when the water flows from back to front in the second part 114, it will be intercepted by the first dam 14, and under the drainage action of the first dam section 141 and the third dam section 143, it will flow to the area where the second dam section 142 is located, and then directly fall down into the first drain outlet 112 for discharge. Compared with the solution of discharging water from the side edge 118 of the main body 11, there is a gap between the first drain outlet 112 and the side edge 118 in the embodiment of the present application, so the drainage distance is relatively shorter and the drainage efficiency is relatively higher; on the other hand, since the two drain outlets are respectively located on both sides of the second dam section 142, no matter what posture the vehicle body is in, the water can be smoothly discharged from the corresponding first drain outlet 112 to prevent water accumulation in the second part 114.

[0102] In one example, the height of the main body 11 gradually decreases from the center to the sides along its length. That is, compared to a horizontal plane, the center of the main body 11 is higher, while the edges are relatively lower. Therefore, when water from the vehicle's roof and front windshield 4 reaches the center of the vent cover 1, it naturally flows from the center to the sides under the action of gravity until it flows into the at least two first drain ports 112 located on both sides, thus ensuring effective drainage.

[0103] FIG5 illustrates a first retaining dam 14 having one end 144 located at the side edge 118 of the main body 11 and the other end 144 located at the front edge 117 of the main body 11. The front edge 117 of the main body 11 is located opposite the rear edge 116. In this case, referring to FIG5 , the first retaining dam 14 includes a first dam section 141, a second dam section 142, and a third dam section 143, which are sequentially connected along the length direction. The second dam section 142 extends along the length direction, and the first dam section 141 and the third dam section 143 are located on opposite sides of the second dam section 142. At least a portion of the first dam section 141 and at least a portion of the third dam section 143 extend along the width direction of the main body 11. As a result, the first retaining dam 14 has an inverted Z-shaped structure or a quasi-L-shaped structure, which can surround the enclosure 12 and the air inlet 123, isolating them from the wet area.

[0104] Compared to the ventilation cover 1 shown in FIG3 , the wet area of ​​the ventilation cover 1 shown in FIG5 is significantly larger than the dry area. In this case, the opening area of ​​the first drain port 112 can be designed to be larger to improve the drainage capacity of the first drain port 112 and thereby improve the drainage efficiency of the wet area. For example, referring to FIG5 , of the two first drain ports 112 , the opening area of ​​the first drain port 112 farther from the enclosure 12 is larger than the opening area of ​​the first drain port 112 closer to the enclosure 12 . Therefore, the first drain port 112 farther from the enclosure 12 clearly has a stronger drainage capacity.

[0105] It should be pointed out that since the two ends of the first dam 14 are located at the side edges 118 of the main body 11 and there is a gap between them and the rear edge 116 of the main body 11, when the ventilation cover 1 is applied to a vehicle, the first dam 14, the main body 11 and the front windshield 4 of the vehicle cooperate to form a drainage opening. When the amount of water flowing into the second part 114 is too large and the drainage speed of the first drainage port 112 is slower than the water accumulation speed, the accumulated water can also be discharged through the drainage opening to relieve the drainage pressure of the first drainage port 112 and prevent the accumulated water from being too high and crossing the first dam 14.

[0106] In one possible scenario, the drainage openings correspond to electronic devices and steel-aluminum lap joints located at the drainage points. While these structures are waterproof, their resistance to water and oxygen corrosion is limited. Frequent drainage into these locations could cause electronic device failures or corrosion of the steel-aluminum lap joints.

[0107] In one example, as shown in Figures 3 and 6 , the vent cover 1 further includes two second dams 15. Both second dams 15 are located in the second portion 114 and stand upright at the two side edges 118 of the main body 11. The dam surface of each second dam 15 is connected to the end 144 of the adjacent first dam 14, and the end 151 of the second dam 15 extends away from the first dam 14 to the rear edge 116 of the main body 11. In other words, in this example, the second dam 15 is located at the location of the aforementioned drain opening. The second dam 15 can, to a certain extent, prevent water from draining from this location, instead allowing water to drain as much as possible from the first drain opening 112. The end 151 of the second dam 15 is located closest to the vehicle's front windshield 4.

[0108] As shown in Figure 7, the height of the second retaining dam 15 is less than the height of the end 144 of the first retaining dam 14 to which it is connected. This arrangement is intended to prevent excessive water accumulation caused by relying solely on the first drain outlet 112 for drainage when the amount of water in the second portion 114 is too large, thereby avoiding the risk of water intrusion into the dry area. For example, during light to moderate rainfall, the amount of water flowing into the second portion 114 is relatively small. In this case, the second retaining dam 15 and the first retaining dam 14 cooperate to intercept the water in the second area and discharge it through the first drain outlet 112. During heavy rainfall, the amount of water flowing into the second portion 114 is relatively large, and the drainage capacity of the first drain outlet 112 is insufficient. In this case, the water can flow over the second retaining dam 15, thereby alleviating drainage pressure and preventing accumulated water from flowing over the higher first retaining dam 14.

[0109] In this embodiment, as described above, the height of the second dam 15 can be determined based on the rainfall. For example, the height of the second dam 15 can be configured such that water cannot flow over the second dam 15 during light or medium rainfall, and water can flow over the second dam 15 during heavy rainfall without flowing over the first dam 14. The light or medium rainfall and heavy rainfall can correspond to rainfall levels in an enhanced rain test on a vehicle, respectively. Alternatively, the light or medium rainfall and heavy rainfall can also be determined based on the drainage capacity of the first drain port 112.

[0110] Optionally, the height of the second dam 15 may be in the range of 10-30 mm, for example, the height may be 14 mm, 17 mm, 20 mm, 22 mm or 25 mm.

[0111] In one example, as shown in Figure 7, the ventilation cover 1 also includes two extended water guides 17, which are respectively connected to the ends 151 of the two second dams 15 and extend in a direction away from the main body 11 to guide the water that has passed over the second water dam to the area between the fender and the shock absorber tower of the vehicle for discharge.

[0112] In some embodiments, at least one of the first dam 14, the second dam 15, and the extended water guide 17 is a flexible structure made of a soft material, such as a soft rubber injection molded therefrom, and has a certain degree of flexibility. Therefore, when the soft structure collides with an external object, such as a pedestrian, the soft structure's inherent flexibility allows it to act as a buffer, absorbing some of the energy of the impact, thereby reducing injuries to the pedestrian and providing pedestrian protection.

[0113] The structural features involved in the second part 114 are introduced below.

[0114] In one example, as shown in FIG8 , the main body 11 is provided with at least two second drain openings 115 . The at least two second drain openings 115 are located in the first portion 113 and are used to promptly drain water from the first portion 113 when water flows over the first retaining dam 14 and into the first portion 113 . The at least two second drain openings 115 are located on opposite sides of the enclosure 12 in the longitudinal direction. For example, in FIG8 , there are two second drain openings 115 , one of which is located between the enclosure 12 and a left edge 118 of the main body 11 and spaced apart from the enclosure 12; the other second drain opening 115 is located between the enclosure 12 and a right edge 118 of the main body 11 and spaced apart from the enclosure 12.

[0115] By providing at least two second drain ports 115 on opposite sides of the enclosure portion 12 in the longitudinal direction, water can be smoothly drained from the corresponding second drain ports 115 regardless of the vehicle's posture. For example, when the vehicle body leans to the left, water accumulated on the main body 11 will flow to the left under the action of gravity and drain from the left second drain port 115. When the vehicle body leans to the right, water accumulated on the main body 11 will flow to the right under the action of gravity and drain from the right second drain port 115.

[0116] This application does not impose any specific restrictions on the shape or style of the second drain outlet 115, as long as drainage is guaranteed. Figure 9 shows a possible structural style of the second drain outlet 115. Referring to Figure 9, each second drain outlet 115 includes a plurality of drainage holes arranged in sequence along the width direction of the ventilation cover 1. The drainage holes are located at the intersection of the bottom plate 1191 and the side plate 1192 of the main body 11. When the vehicle body tilts to one side, the accumulated water on the main body 11 will flow to that side and accumulate on the side plate 1192 located on that side, and then be discharged from the corresponding second drain outlet 115, thereby ensuring the drainage effect.

[0117] Alternatively, as shown in FIG9 , the spacing between two adjacent drainage holes gradually increases from the front to the rear. Water flowing into the first portion 113 will flow forward and is more likely to accumulate at a position further forward in the first portion 113. Therefore, the plurality of drainage holes are arranged in a manner that becomes denser as they move forward. In other words, the arrangement of the plurality of drainage holes corresponds to the distribution of water, thereby achieving a better drainage effect.

[0118] The width of the drainage holes can be configured by technicians according to layout requirements, and the present application embodiment does not impose specific restrictions on this, as long as sufficient drainage capacity is ensured and the water level in the first portion 113 does not exceed the enclosure 12. For example, the diameter of each drainage hole can range from 3 to 6 mm, for example, a diameter of 4 mm or 5 mm.

[0119] Furthermore, as mentioned above, the height of the main body 11 gradually decreases from the middle to the sides in the longitudinal direction. Therefore, when water enters the first portion 113 and reaches the middle, it will naturally flow from the middle to the sides under the action of gravity until it flows into the at least two second drain ports 115 located on both sides.

[0120] Furthermore, to further ensure the drainage effect, in one example, at least two second drainage ports 115 are respectively located at the lowest positions at both ends of the main body 11 in the first portion 113 , that is, at the side edges 118 of the main body 11 .

[0121] Figures 10 and 11 respectively illustrate the placement of the enclosure 12 within the first portion 113. As shown in Figure 10 , a first gap 161 is defined between the enclosure 12 and the stopper 16 of the vent cover 1. The stopper 16 is connected to the front edge 117 of the main body 11 and is used to mount a sealing strip. The presence of first gap 161 prevents direct contact between the enclosure 12 and the stopper 16. This allows water flowing through the stopper 16 to flow along the first gap 161 toward the second drain outlets 115 on either side and be discharged, rather than accumulating at the stopper 16. This prevents excessive water accumulation at the stopper 16, which could cause water to overflow the front end 124 of the enclosure 12. As shown in Figure 11 , a second gap 126 is defined between the enclosure 12 and the first dam 14. This gap 126 prevents water from overflowing the first dam 14 and directly reaching the top of the enclosure 12 and entering the air inlet 123.

[0122] The widths of the first gap 161 and the second gap 126 can be configured by technicians according to layout requirements, and the present embodiment does not impose specific restrictions on this. It is sufficient to ensure that the first gap 161 can form a sufficiently large drainage space to prevent the accumulated water at the stop portion 16 from flowing over the front end 124 of the enclosure portion 12, and to ensure that the second gap 126 can keep the enclosure portion 12 far enough away from the first retaining dam 14 so that water flowing over the first retaining dam 14 does not directly fall onto the top end 122 of the enclosure portion 12. For example, the width of the first gap 161 can range from 1 to 5 mm, for example, its width can be 2 mm, 3 mm, 4 mm, etc.; the width of the second gap 126 can range from 1 to 5 mm, for example, its width can be 2 mm, 3 mm, 4 mm, etc.

[0123] It is easy to understand that because water on the vehicle's roof and front windshield 4 hits the first dam 14 at a relatively high speed, a large amount of water mist may form near the first dam 14 and float in the air. When the air conditioning system is in operation, negative pressure is generated, which draws air around the air inlet 123 into the air inlet 123. This may cause the inhalation of a large amount of air carrying water mist, causing damage to the air conditioning system and a large amount of water vapor to enter the passenger compartment, causing discomfort to the driver and passengers.

[0124] To further enhance the water-proofing effect on the air inlet 123, in one example, as shown in FIG12 , the vent cover 1 further includes a brim 18 , which is located above the air inlet 123 and connected to the first dam 14 . The brim 18 can provide a barrier above the air inlet 123. This prevents water from flowing over the first dam 14 and into the air inlet 123. Furthermore, the brim 18 isolates the air carrying water mist from the air inlet 123, significantly reducing the moisture content of the outside air entering the air inlet 123. This protects the air conditioning system from water and oxygen erosion and ensures a comfortable environment within the passenger compartment. The term "above" the air inlet 123 refers to the side of the air inlet 123 away from the opening 111.

[0125] Exemplarily, the orthographic projection of the air inlet 123 on the plane where the opening 111 is located is located within the orthographic projection of the brim 18 on the plane where the opening 111 is located, that is, the air inlet 123 is completely covered by the covering range of the brim 18 to ensure that the brim 18 effectively protects the air inlet 123.

[0126] It should be noted that a distance needs to be maintained between the brim portion 18 and the air inlet 123 , that is, the brim portion 18 does not contact the top end 122 of the enclosure portion 12 to avoid affecting the air intake effect of the air inlet 123 .

[0127] In the embodiment of the present application, a retaining portion 12 is protruded from the main body 11 of the ventilation cover 1. The retaining portion 12 surrounds the opening 111 and, above the opening 111, defines an air inlet 123 that is at least partially inclined relative to the opening 111. Since the air inlet 123 has a larger air intake area than the opening 111, the air intake volume is increased compared to a solution that directly intakes air through the opening 111, and the air intake performance of the air conditioner is effectively improved. Furthermore, the ventilation cover 1 also has a first retaining dam 14 that separates the main body 11 into a dry area and a wet area that are not connected to each other. The air inlet is located in the dry area to achieve the air intake function, and a number of drainage structures, such as the first drainage port 112 and the second retaining dam 15, are provided in the wet area to achieve the drainage function and prevent water from flowing into the dry area as much as possible.

[0128] Furthermore, to address the occasional ingress of water into the dry area, a second drain port 115 is provided within the dry area to promptly drain water that has entered the dry area, thereby preventing the risk of water ingress into the air inlet 123 caused by water accumulation in the dry area. Furthermore, to address the issue of large amounts of water mist generated by the impact of water flow being drawn into the air conditioning system's negative pressure, a brim portion 18 is further provided above the air inlet 123 to effectively isolate the air inlet 123 from high-water content air, thereby reducing the amount of high-water content air drawn into the air inlet 123. Therefore, the ventilated cover 1 achieves the goal of increasing the air intake volume of the air inlet 123 while preventing water from entering the air inlet 123.

[0129] The present application also provides a front cabin drainage and air intake system. Figure 13 is a schematic structural diagram of the front cabin drainage and air intake system. As shown in Figure 13, the system includes an air guide 2, a drainage member 3, and the aforementioned ventilation cover 1. The air guide 2 and drainage member 3 are both located below the ventilation cover 1.

[0130] Air guide 2 is used to form an airflow channel. It can be connected to opening 111 on ventilation cover 1 to receive outside air flowing in through opening 111 and introduce it into the vehicle's air conditioning system to achieve air supply. Under the negative pressure of the air conditioning system, outside air enters through air inlet 123 and flows into the air conditioning system through opening 111 and air guide 2 in sequence.

[0131] In one example, the air guide member 2 may be, for example, an air guide pipe, as shown in Figures 14 and 15 , the air guide pipe includes a first pipe segment 21 and a second pipe segment 22. One end of the first pipe segment 21 is connected to the opening 111, and the other end is connected to the second pipe segment 22. The first pipe segment 21 is bent relative to the second pipe segment 22, and an angle α between the first pipe segment 21 and the second pipe segment 22 is less than 90°.

[0132] It should be noted that when this front compartment drainage and air intake system is used in a vehicle, the second section 22 of the air duct should form an angle β with the horizontal line, with 0°<β<180°. This ensures that when water enters the air inlet 123 and flows along the inner wall into the air duct, and when water vapor in the air condenses on the duct wall to form water droplets, the water droplets will naturally drip to the bottom of the duct under the action of gravity, rather than moving along the duct wall toward the air conditioning system.

[0133] Optionally, the longitudinal cross-section of the second pipe section 22 is trumpet-shaped, that is, the further away from the first pipe section 21 the second pipe section 22 is, the larger its cross-sectional area is, thereby ensuring sufficient air suction volume and at the same time ensuring that water droplets hanging on the pipe wall of the second pipe section 22 can flow to the first pipe section 21, thereby away from the air-conditioning system.

[0134] For water dripping on the bottom of the air duct, as shown in Figure 16, a third drain outlet 23 is also provided at the bottom of the air duct. The third drain outlet 23 is located at the bottom of the air duct, that is, the lowest position on the air duct. For example, when the air duct is arranged in the orientation shown in Figure 15, the third drain outlet 23 can be located at the connection between the first pipe section 21 and the second pipe section 22 to ensure that all accumulated water in the air duct can be discharged.

[0135] The drainage member 3 is used to form a drainage channel, which can be connected to the first drainage port 112 on the ventilation cover 1 to guide the water flowing in from the first drainage port 112 to a set drainage position for discharge.

[0136] In one example, the drainage member 3 extends from one end of the first drainage port 112 toward the bottom guard plate of the vehicle, and is used to guide the water flowing into the first drainage port 112 to the bottom guard plate and discharge it out of the vehicle through the openings on the bottom guard plate.

[0137] In one example, two drain members 3 are provided corresponding to the two first drain openings 112 on the main body 11 of the ventilating cover 1, and a relatively large space is formed between the two drain members 3. Therefore, this embodiment is particularly suitable for vehicles with a reinforcing beam in the middle of the front cabin, such as a V-shaped beam, and a relatively short length between the shock tower and the front panel area.

[0138] Specifically, some vehicles have V-shaped beams installed on the front cabin frame to improve the frame's stiffness and modal properties. However, this V-shaped beam encroaches on the front cabin space, making it impossible to arrange a large, cross-cabin water trough. The front cabin drainage and air intake system provided in the present embodiment only has two small drainage components 3 connected to the first drainage outlet 112 on either side of the ventilation cover 1. The space between these two drainage components 3 is left vacant to accommodate the V-shaped beam arrangement.

[0139] An embodiment of the present application further provides a vehicle, which includes the above-mentioned ventilation cover 1, or the vehicle includes the above-mentioned front cabin drainage and air intake system.
