[0040] It should also be noted that in the drawings of the embodiments of the present application, the arrows marked X, Y, and Z respectively represent the first direction X, the second direction Y, and the third direction Z. The description of the present application introduces the first direction X, the second direction Y, and the third direction Z to more clearly express the relative positional relationship involved in the present application, wherein the first direction X, the second direction Y, and the third direction Z are three relative directions that intersect with each other, rather than absolute directions. In actual applications, the first direction X, the second direction Y, and the third direction Z can point to any direction in space as long as the intersection relationship between the two is maintained.

[0041] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the components and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0042] The ventilation cover is located in the front cabin of the vehicle body. The connection form and structure of the front cabin of the vehicle body are related to the pedestrian protection performance of the vehicle.

[0043] In actual use of the vehicle, when a pedestrian collides with the front cabin of the vehicle, the ventilation cover is too rigid to deform and absorb energy in time, causing greater damage to the pedestrian.

[0044] In order to solve the technical problem that the ventilation cover cannot be deformed in time to absorb the energy generated by the collision after the collision, causing great harm to pedestrians, the first embodiment of the present application provides a ventilation cover. Figure 1 and Figure 2 The ventilation cover includes a support beam 100 and a cover 200; the cover 200 is located on one side of the support beam 100, and the cover 200 includes a connecting portion 260 and a main body 210, the connecting portion 260 is connected to the support beam 100, and the connecting portion 260 is connected to the cover 200; at least part of the main body 210 is spaced apart from the main body 210.

[0045] In some embodiments, the connection portion 260 is connected to one side of the body 210 along a first direction X, where the first direction X is a front-to-back direction, so that when the vent cover is applied to a vehicle, the connection portion 260 is located in front of the body 210 .

[0046] In some embodiments, the cover plate 200 is connected to one side of the support beam 100 along the third direction Z, such that when the cover plate 200 is used in a vehicle, the cover plate 200 is connected above the support beam 100, that is, at least a portion of the body portion 210 is spaced apart from the support beam 100 along the third direction Z. In some embodiments, the third direction Z is a vertical direction.

[0047] In some embodiments, the body portion 210 is completely spaced apart from the support beam 100 .

[0048] In some embodiments, part of the body portion 210 is connected to the support beam 100, and part of the body portion 210 is spaced apart from the support beam 100. In some embodiments, both ends of the body portion 210 along the second direction Y contact both ends of the support beam 100 along the first direction X, and a middle portion of the body portion 210 along the second direction Y is spaced apart from a middle portion of the support beam 100 along the second direction Y.

[0049] In some embodiments, when the ventilated cover is applied to a vehicle, the support beam 100 can connect two shock tower tops of the vehicle, thereby improving the rigidity of the front portion of the vehicle.

[0050] On the one hand, in the above embodiment, because at least a portion of the main body 210 is spaced apart from the support beam 100, when the main body 210 is impacted by the support beam 100, the portion of the main body 210 spaced apart from the support beam 100 can deform toward the support beam 100, thereby allowing the main body 210 to absorb the energy of the impact through deformation. When this vent cover is used in a vehicle, if a pedestrian directly strikes the vent cover or indirectly strikes the vent cover through the hood 500, at least a portion of the vent cover can deform toward the support beam 100 to absorb the pedestrian's impact energy, thereby reducing the severity of pedestrian injuries.

[0051] On the other hand, in the above embodiment, by setting the connecting portion 260, the main body 210 can be connected to the support beam 100 while being spaced apart from the support beam 100, so that the ventilation cover can obtain better support when no collision occurs and the connection is more stable.

[0052] In some embodiments, the vent cover includes a plurality of connection portions 260 , and the plurality of connection portions 260 are spaced apart along the second direction Y, where the second direction Y is the left-right direction.

[0053] In the above embodiment, a plurality of connecting portions 260 are provided to enhance the connection stability between the main body 210 and the support beam 100. By arranging the plurality of connecting portions 260 at intervals, the support of the main body 210 by the connecting portions 260 can be more dispersed. When the main body 210 is impacted, it can be deformed toward the support beam 100 and absorb the energy generated by the impact.

[0054] In some embodiments, the dimensions of the connection portion 260 at different locations along the third direction Z are different, so that part of the body portion 210 can be connected to the support beam 100, and part of the body portion 210 can be spaced apart from the support beam 100 along the third direction Z. Figure 1 and Figure 2 , along the second direction Y, the size of the connecting parts 260 near the two ends along the third direction Z is smaller, and the size H between the main body 210 and the support beam 100 along the third direction Z is smaller; the size of the connecting parts 260 near the middle along the third direction Z is larger, and the size H between the main body 210 and the support beam 100 along the third direction Z is larger.

[0055] In some embodiments, see Figure 1 and Figure 2The cover plate 200 has a through hole 221, and the ventilation cover plate also includes a water guide 300, which has a receiving cavity 310. The water guide 300 is connected to the main body 210, and the through hole 221 is connected to the receiving cavity 310. The water guide 300 is spaced apart from the support beam 100.

[0056] In some embodiments, the water guide 300 is disposed on one side of the body 210 along the third direction Z so that the water guide 300 can be connected to the bottom of the body 210. In some embodiments, the water guide 300 is spaced apart from the support beam 100 along the first direction X so that the water guide 300 is located behind the support beam 100.

[0057] It can be understood that the water guide member 300, which has a hollow structure and extends along the second direction Y and is connected to the side of the main body 210 close to the support beam 100, can prevent the main body 210 from deforming toward the support beam 100, and the larger the size of the water guide member 300 along the second direction Y, the stronger the blocking effect.

[0058] In the above embodiment, since the main body 210 and the support beam 100 are spaced apart, the height of the main body 210 is raised, so that the space below the main body 210 is larger, and the water guide member 300 can be allowed to obtain a larger size in the third direction Z from the main body 210 to the water guide member 300, so that the size of the water guide member 300 along the second direction Y can be reduced while the volume of the accommodating cavity 310 remains unchanged, thereby reducing the effect of the water guide member 300 on the rigidity reinforcement of the main body 210, and reducing the obstruction of the water guide member 300 to the deformation of the main body 210 toward the support beam 100 after the main body 210 is impacted, thereby ensuring that the ventilation cover has good water-conducting performance while also having good safety performance.

[0059] In some embodiments, the water guide 300 is a plastic member.

[0060] In some embodiments, the water guide 300 is connected to the first sub-portion 220 and the second sub-portion 230 through holes respectively.

[0061] In some embodiments, see Figure 4 and Figure 5 , the support beam 100 protrudes in a direction away from the water guide 300 .

[0062] In some embodiments, the support beam 100 protrudes forward along the first direction X.

[0063] In the above embodiment, the support beam 100 protrudes in the direction away from the water guide member 300, which allows the support beam 100 to remain as far away from the water guide member 300 as possible without changing the position of the connection point with the frame. The size of the water guide member 300 along the first direction X can be further increased, and while the volume of the accommodating cavity 310 remains unchanged, the size of the water guide member 300 along the second direction Y can be further reduced, so that the main body 210 is more likely to deform toward the support beam 100 when impacted, and absorb the energy of the impact, thereby reducing the damage to pedestrians caused by the impact.

[0064] In some embodiments, see Figure 4 and Figure 5 , along the direction from the connecting portion 260 to the supporting beam 100 , the supporting beam 100 has a first orthographic projection, the main body 210 has a second orthographic projection, and a portion of the first orthographic projection is located outside the second orthographic projection.

[0065] In some embodiments, the first orthographic projection is the orthographic projection of the support beam 100 on the plane where the surface facing the main body 210 is located, and the second orthographic projection is the orthographic projection of the main body 210 on the plane where the surface of the support beam 100 facing the main body 210 is located.

[0066] Specifically, the support beam 100 protrudes away from the water guide 300 so that the first orthographic projection is offset from the second orthographic projection, thereby causing a portion of the first orthographic projection to move out of the range of the second orthographic projection.

[0067] In the above embodiment, the portion of the first orthographic projection is located outside the second orthographic projection, which can reduce the portion of the main body 210 blocked by the support beam 100 when the main body 210 is deformed toward the support beam 100, allowing the main body 210 to deform to a greater extent toward the support beam 100, thereby achieving better energy absorption and reducing the degree of pedestrian injury.

[0068] In some embodiments, see Figure 3 、 Figure 4 and Figure 5 The main body 210 includes a first sub-section 220 and a second sub-section 230. The first sub-section 220 is connected to the connecting section 260 and has a through hole 221. The second sub-section 230 is connected to a side of the first sub-section 220 away from the connecting section 260 and has a water guide groove 231.

[0069] In some embodiments, the water guide groove 231 penetrates the main body 210 along the second direction Y, so as to enable the liquid to be guided to both sides of the ventilation cover.

[0070] In some embodiments, the second sub-portion 230 has a connection hole, which is located on a side of the water guide groove 231 away from the first sub-portion 220 , and is used to connect to a wiper.

[0071] In some embodiments, the first sub-section 220 is disposed in front of the second sub-section 230 .

[0072] In the above embodiment, a water guide groove 231 is provided in the second sub-section 230 to collect and guide the liquid, and a through hole 221 is provided in the first sub-section 220 on one side of the second sub-section 230 so that the liquid overflowing from the water guide groove 231 can flow from the through hole 221 to the accommodating cavity 310 of the water guide member 300. The flow path of the liquid is controllable, thereby improving the reliability of the ventilation cover.

[0073] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 and Figure 4 The main body 210 also includes a protrusion 240, which is arranged on the side of the main body 210 away from the support beam 100. The protrusion 240 is connected to the first sub-section 220. The first sub-section 220 has a plurality of through holes 221. The protrusion 240 is located between some of the through holes 221 and the water guide groove 231.

[0074] Specifically, the first subsection 220 includes a first region and a second region connected to each other along the first direction X. The second region is located on a side of the first region near the second subsection 230. Some through-holes 221 are located in the first region, and the protrusions 240 are located in the second region. The first subsection 220 also includes a third region. The first and second regions are connected to the same side of the third region along the second direction Y, and some through-holes 221 are located in the third region. Liquid overflowing from the water channel 231, blocked by the protrusions 240 in the second region, preferentially flows toward the through-holes 221 located in the third region.

[0075] It is understandable that not only liquid but also gas can enter the through hole 221 .

[0076] In some embodiments, the vehicle's air conditioning system needs to introduce air from the water guide 300 .

[0077] In the above embodiment, the protrusion 240 is provided so that liquid overflowing from the water channel 231 can flow only toward a portion of the through-holes 221. This portion of the through-holes 221 can serve as the water inlet 223. Since the other portion of the through-holes 221 are blocked by the protrusion 240, liquid overflowing from the water channel 231 will not preferentially flow toward the blocked through-holes 221. The blocked through-holes 221 can be used to introduce gas into the accommodating cavity 310 of the water guide 300. That is, by providing the protrusion 240 to functionally differentiate the multiple through-holes 221, some through-holes 221 are used to introduce liquid into the accommodating cavity 310, while some through-holes 221 are used to preferentially introduce gas into the accommodating cavity 310. This allows the through-holes 221 and the water guide 300 having the accommodating cavity 310 to achieve the function of introducing gas.

[0078] It is understandable that when the liquid flow is large, the liquid can also bypass the protrusion 240 from both sides of the protrusion 240 along the second direction Y or the side away from the first sub-portion 220 in the third direction Z and enter the accommodating cavity 310 through the blocked through hole 221.

[0079] In some embodiments, see Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , multiple through holes 221 include a water inlet hole 223 and an air inlet hole 222, and the protrusion 240 is located between the air inlet hole 222 and the water guide groove 231; the water guide member 300 has a first sub-cavity 311, a water outlet hole 330, a second sub-cavity 312 and an air outlet hole 320, the first sub-cavity 311 is connected to the water inlet hole 223; the water outlet hole 330 is connected to the first sub-cavity 311; the second sub-cavity 312 is connected to the air inlet hole 222, the second sub-cavity 312 is connected to the first sub-cavity 311 and forms a accommodating cavity 310; the air outlet hole 320 is connected to the second sub-cavity 312.

[0080] It can be understood that the air inlet 222 is provided in the first area, and the water inlet 223 is provided in the third area.

[0081] In the above embodiment, an air outlet hole 320 and a water outlet hole 330 connected to the accommodating chamber 310 are provided on the water guide member 300 so that the water guide member 300 can discharge the gas and liquid introduced into the accommodating chamber 310, and the second sub-cavity 312 connected to the air outlet hole 320 is connected to the air inlet hole 222, and the first sub-cavity 311 connected to the water outlet hole 330 is connected to the water inlet hole 223, so that the water guide member 300 not only has the function of guiding liquid, but also has the function of guiding gas.

[0082] In some embodiments, see Figure 5 、 Figure 6 and Figure 7The water guide 300 has a first bottom surface 340, a second bottom surface 350 and a mounting surface 360. The first bottom surface 340 faces the main body 210 and is used to enclose a first sub-cavity 311. The water outlet 330 is set on the first bottom surface 340; the second bottom surface 350 faces the main body 210 and is used to enclose a second sub-cavity 312. The mounting surface 360 faces the main body 210 and is connected to the main body 210; along the direction from the connecting portion 260 to the support beam 100, the minimum distance between the first bottom surface 340 and the mounting surface 360 is greater than the maximum distance between the second bottom surface 350 and the mounting surface 360.

[0083] Specifically, see Figure 6 and Figure 7 The minimum distance between the first bottom surface 340 and the mounting surface 360 is h1, and the maximum distance between the second bottom surface 350 and the mounting surface 360 is h2. The minimum distance between the first bottom surface 340 and the mounting surface 360 is greater than the maximum distance between the second bottom surface 350 and the mounting surface 360, that is, h1 and h2 need to satisfy: h1>h2.

[0084] Furthermore, in some embodiments, the distance between the first bottom surface 340 and the vehicle load-bearing plane is smaller than the distance between the second bottom surface 350 and the vehicle load-bearing plane, that is, the first bottom surface 340 is lower than the second bottom surface 350, and the liquid located on the second bottom surface 350 has a tendency to flow toward the first bottom surface 340, i.e., the first sub-cavity 311, under the action of gravity.

[0085] In the above embodiment, by limiting the relationship between the minimum distance between the first bottom surface 340 and the mounting surface 360 and the maximum distance between the second bottom surface 350 and the mounting surface 360, the depth of the first sub-cavity 311 is limited to be greater than the depth of the second sub-cavity 312, so that the liquid entering the second sub-cavity 312 for guiding gas can flow toward the first sub-cavity 311 under the action of gravity, thereby reducing the possibility of liquid entering the air outlet 320 and improving the reliability of the water guide 300.

[0086] In some embodiments, see Figure 6 and Figure 7 The ventilation cover also includes a seal 400; the main body 210 also includes a sealing sub-section 250, which is connected to the side of the first sub-section 220 away from the second sub-section 230, and the sealing sub-section 250 is connected to the connecting portion 260. The seal 400 is arranged on the side of the main body 210 away from the support beam 100 and is sealed and connected to the sealing sub-section 250.

[0087] In some embodiments, the seal 400 is connected to the lower surface of the hood 500. When the hood 500 is closed, the seal 400 will follow the hood 500 to rotate toward the sealing sub-section 250 until the hood 500 is closed, the seal 400 will be deformed, and will be sealed and connected to the sealing sub-section 250.

[0088] In some embodiments, the hood 500 is an engine hood; in some embodiments, the hood 500 is a trunk lid 200 .

[0089] On the one hand, in the above embodiment, by providing a sealing sub-section 250 that can be sealed with the sealing member 400, the liquid that has not entered the through hole 221 can be prevented from continuing to flow toward the engine compartment or the front trunk, thereby improving the sealing performance of the ventilation cover.

[0090] On the other hand, in the above embodiment, by providing the seal 400, the liquid that has not entered the through hole 221 can be gathered in the space formed by the seal 400 and the first sub-section 220, so that the liquid can be introduced into the through hole 221 after the liquid accumulates to a certain extent, thereby improving the guiding function of the ventilation cover for the liquid.

[0091] In some embodiments, see Figure 6 and Figure 7 The water guide groove 231 has a first groove wall 232 and a second groove wall 233 that are opposite to each other along the first direction X, and the first groove wall 232 is connected to the first sub-section 220; the first sub-section 220 has a first surface 224 and a second surface 225 connected along the first direction X, the first surface 224 is connected to the second sub-section 230, and the second surface 225 is connected to the sealing sub-section 250, the second surface 225 is opposite to the first groove wall 232 along the first direction X and faces the sealing member 400, and both the first surface 224 and the second surface 225 are provided with a through hole 221.

[0092] In the above embodiment, when the liquid overflows from the water-guiding groove 231 and does not immediately enter the through hole 221 and accumulates in the space surrounded by the sealing member 400, the first surface 224 and the sealing sub-portion 250, when the liquid level in the space reaches a certain height, it can enter the accommodating cavity 310 through the through hole 221 of the first surface 224, thereby further improving the water-guiding performance of the ventilation cover.

[0093] In some embodiments, the ventilation cover further includes a connecting member 600 , which is connected to a side of the support beam 100 facing away from the cover 200 , and the connecting member 600 is used to connect the support beam 100 and the vehicle frame.

[0094] Correspondingly, the present application also provides a vehicle, comprising a ventilation cover as described in any one of the above embodiments.

[0095] Here's how the vent cover works when applied to a vehicle and hit:

[0096] When a pedestrian collides with the hood 500, the hood 500 presses the ventilation cover body 210. Since there is a gap between the body 210 and the support beam 100, and the positive projection of the body 210 and the positive projection of the support beam 100 are staggered along the third direction Z, the body 210 can deform toward the support beam 100 to absorb the energy generated by the collision and reduce the degree of injury to the pedestrian.

[0097] The following is the working principle of the ventilation cover when it is used to guide water in a vehicle:

[0098] The liquid flows toward the water channel 231 and is guided by the water channel 231 to both sides of the vehicle and out of the vehicle. Part of the liquid overflowing from the water channel 231 is blocked by the protrusion 240 and can only flow toward the unobstructed through hole 221, and then flows through the through hole 221 to the accommodating cavity 310 and out of the vehicle through the water outlet 330.

[0099] The above is a detailed introduction to a ventilation cover and a vehicle provided in the embodiments of the present application.
