Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] The following is for reference. Figures 1-5 Describes a vehicle 1000 according to an embodiment of the present utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a partial top view of a vehicle according to an embodiment of the present utility model, specifically a top view of the right half of the front half of the vehicle 1000. The vehicle 1000 typically includes a windshield 1, a ventilation cover 2, a hood 3, and a drainage channel 4. In the longitudinal direction of the vehicle 1000, the rear end of the ventilation cover 2 is sealed to the windshield 1, and the front end of the ventilation cover 2 extends downward toward the hood 3 and is sealed to the hood 3, thereby defining a ventilation opening 5 between the ventilation cover 2 and the hood 3.

[0023] The water trough 4 is located below the ventilation cover 2. The ventilation cover 2 has an air conditioning inlet 23 that connects the ventilation opening 5 and the water trough 4. The inner wall of the water trough 4 is also provided with an air inlet 41 for the vehicle's air conditioning. When the air conditioning of the vehicle 1000 is turned on, outside air can enter the air inlet 41 of the vehicle's air conditioning through the ventilation opening 5, the air conditioning inlet 23 and the water trough 4 in sequence.

[0024] However, when vehicle 1000 is in motion, outside air enters the water channel 4 through the vent 5 and air conditioning inlet 23, and then enters the front compartment of the vehicle through the gap between the water channel 4 and the front compartment, creating turbulence, increasing the wind resistance of vehicle 1000, and affecting the energy consumption of vehicle 1000. In order to reduce the wind resistance of vehicle 1000, this utility model embodiment proposes a vehicle.

[0025] Reference Figure 3 , Figure 4 and Figure 5 In the vehicle of this utility model embodiment, the ventilation cover 2 includes: a cover body 21 and a sealing member 22, wherein the front and rear ends of the cover body 21 are respectively sealed to the hood 3 and the windshield 1, and the cover body 21 is also provided with an air conditioning inlet 23 for connecting the ventilation opening 5 and the water channel 4, the air conditioning inlet 23 being located on the side of the ventilation opening 5 away from the windshield 1; the sealing member 22 is movably provided on the cover body 21 to block or avoid the ventilation opening 5.

[0026] In some application scenarios, when vehicle 1000 is in motion, seal 22 is in a state of blocking vent 5. Outside air cannot flow through vent 5 to air conditioning inlet 23, nor can it enter water channel 4 or the front compartment of the vehicle. This effectively reduces the wind resistance of vehicle 1000, lowering its drag coefficient by 2-3 counts and extending its driving range by at least 2km. When vehicle 1000 needs air intake through air conditioning inlet 41, seal 22 moves to avoid vent 5. Outside air can then enter the vehicle's air conditioning inlet 41 through vent 5, air conditioning inlet 23, and water channel 4 in sequence, ensuring the stable operation of the vehicle's air conditioning system.

[0027] According to the vehicle of this utility model embodiment, when the vehicle 1000 needs air intake through the air conditioning air inlet 41, the seal 22 moves to avoid the vent 5, ensuring the stable operation of the vehicle's air conditioning. When air intake through the air conditioning air inlet 41 is not needed, the seal 22 can move to close the vent 5, effectively reducing the wind resistance of the vehicle 1000. The wind resistance coefficient of the vehicle 1000 can be reduced by 2 to 3 counts, which not only extends the driving range of the vehicle 1000 by at least 2 km, but also improves the driving stability of the vehicle 1000 and reduces wind noise.

[0028] In some embodiments, the cover body 21 has a protrusion extending toward the cover 3, and a vent 5 is defined between the protrusion and the cover 3. The seal 22 is movably disposed on the protrusion.

[0029] In this embodiment of the utility model, the distance between the cover plate body 21 and the machine cover 3 is reduced by the protrusion, which is beneficial to reduce the maximum opening area of ​​the ventilation port 5. That is, the travel distance of the sealing member 22 from completely avoiding the ventilation port 5 to completely blocking the ventilation port 5 can be reduced, which is beneficial to reduce the range of motion of the sealing member 22, simplify the structure of the ventilation cover plate 2, and reduce the cost of the ventilation cover plate 2.

[0030] For example, the seal 22 is slidably disposed on the protrusion, and the seal 22 can slide to abut against the cover 3 to block the vent 5.

[0031] It should be understood that the sealing element 22 is not limited to being slidably connected to the cover plate body 21. In other embodiments, the sealing element 22 can also be rotatably connected to the cover plate body 21, as long as the sealing element 22 can move to block or avoid the vent 5. This utility model does not limit this.

[0032] In some specific embodiments, in the front-to-back direction, the cover body 21 includes a first plate portion 211, a second plate portion 212, a third plate portion 213, a fourth plate portion 214, a fifth plate portion 215, a sixth plate portion 216, and a seventh plate portion 217 connected in sequence. The first plate portion 211 is sealed to the inside of the hood 3. The end of the second plate portion 212 away from the first plate portion 211 extends downward at least. The end of the third plate portion 213 away from the second plate portion 212 extends backward at least. The end of the fourth plate portion 214 away from the third plate portion 213 extends upward at least. The end of the fifth plate portion 215 away from the fourth plate portion 214 extends backward at least. The end of the sixth plate portion 216 away from the fifth plate portion 215 extends downward at least. The end of the seventh plate portion 217 away from the sixth plate portion 216 extends backward at least. The seventh plate portion 217 is sealed to the windshield 1.

[0033] The fourth plate portion 214, the fifth plate portion 215, and the sixth plate portion 216 define protrusions, and an air conditioning inlet 23 is formed on the fourth plate portion 214. By setting the air conditioning inlet 23 in the vertically arranged fourth plate portion 214, the risk of external debris such as sand and leaves passing through the air conditioning inlet 23 can be reduced, thereby improving the reliability of the vehicle 1000.

[0034] In some specific embodiments, the cover 3 includes an inner plate 31 and an outer plate 32. The inner plate 31 is disposed below the outer plate 32 and connected to the outer plate 32. The front end of the cover body 21 is sealed to the inner plate 31 through a sealing strip 7. The sealing element 22 is adapted to abut against the inner plate 31 to block the ventilation opening 5.

[0035] In some embodiments, the seal 22 is configured to adjust the opening area of ​​the vent 5 to adjust the air intake volume.

[0036] Through the above technical solution, the vehicle 1000 can adjust the opening area of ​​the vent 5 according to the air volume requirements of the air conditioner, so as to avoid the vent 5 opening area being too large, which would cause excess air to enter the front compartment of the vehicle, increase the wind resistance of the vehicle 1000, and reduce the impact of the air conditioner intake on the wind resistance of the vehicle 1000.

[0037] In some embodiments, the seal 22 is slidable relative to the cover body 21 to adjust the opening area of ​​the vent 5.

[0038] In this embodiment of the utility model, the sealing element 22 is slidably connected to the cover plate body 21, which is a simple connection method and reduces the cost of the ventilation cover plate 2.

[0039] In some embodiments, the seal 22 is slidably disposed on the cover body 21 and passes through the cover body 21. The seal 22 has a first state and a second state. In the first state, the seal 22 slides to abut against the cover 3 to block the vent 5. In the second state, the seal 22 slides to not protrude from the cover body 21 to avoid the vent 5.

[0040] Furthermore, the seal 22 is configured to be positioned at any position between the first and second states to adjust the opening area of ​​the vent 5.

[0041] In this embodiment of the utility model, the way the sealing element 22 and the cover plate body 21 are matched is simple, which reduces the assembly difficulty of the ventilation cover plate 2 and the cost of the ventilation cover plate 2.

[0042] In some specific embodiments, the seal 22 is slidably disposed between the fourth plate portion 214 and the sixth plate portion 216, and passes through the fifth plate portion 215. Because both the fourth plate portion 214 and the sixth plate portion 216 extend at least in the vertical direction, the seal 22 is slidably disposed between the fourth plate portion 214 and the sixth plate portion 216 so that the seal 22 can slide to abut against the cover 3 on the upper side of the cover body 21, reducing the difficulty of the seal 22 blocking the ventilation opening 5 and reducing the cost of the ventilation cover 2.

[0043] Reference Figure 2 In some embodiments, a portion of the cover body 21 is formed in a grille shape to define the air conditioning inlet 23.

[0044] Specifically, at least a portion of the fourth plate 214 is formed in a grille shape to define the air conditioning inlet 23.

[0045] In this embodiment of the utility model, the grille-like structure defines the air conditioning inlet 23, further reducing the risk of external debris such as sand and leaves passing through the air conditioning inlet 23, and improving the reliability of the vehicle 1000.

[0046] Reference Figure 4 and Figure 5 In some embodiments, the ventilation cover 2 further includes a first drive assembly 6, which is connected to the seal 22 to drive the seal 22 to move.

[0047] In this embodiment of the utility model, the ventilation cover 2 is provided with a first driving component 6, which eliminates the need for manual adjustment by the user, reduces the difficulty of movement of the seal 22, and improves the convenience of adjusting the seal 22.

[0048] In some embodiments, the first drive assembly 6 includes a drive motor 61 and a transmission gear 62, the output shaft of the drive motor 61 is connected to the transmission gear 62, and the seal 22 is provided with a rack 221 that meshes with the transmission gear 62.

[0049] When the output shaft of the drive motor 61 rotates, it drives the transmission gear 62 to rotate. The transmission gear 62 drives the rack 221 to slide, thereby driving the seal 22 to slide. In this embodiment of the present invention, the structure of the first drive assembly 6 is simple, reducing the cost of the ventilation cover 2. It should be understood that in other embodiments, the first drive assembly 6 can also be an electric push rod or other structures, as long as it can drive the seal 22 to slide. The present invention does not limit this.

[0050] In some embodiments, the first drive component 6 is fixed to the cover plate body 21.

[0051] In this embodiment of the present invention, the first drive assembly 6 is fixed to the cover plate body 21, so that the cover plate body 21, the seal 22 and the first drive assembly 6 form an integral installation module, which facilitates the assembly of the ventilation cover plate 2 on the vehicle 1000.

[0052] In some embodiments, the ventilation cover 2 includes a first drive assembly 6 for driving the seal 22 to move. The vehicle 1000 also includes a control module 8 and a first detection module 9. The control module 8 is communicatively connected to the first drive assembly 6, and the first detection module 9 is communicatively connected to the control module 8. The control module 8 is used to control the working state of the first drive assembly 6 according to the air conditioning air volume demand signal and / or vehicle speed information obtained by the first detection module 9.

[0053] Specifically, the control module 8 is communicatively connected to the first drive component 6 via a wire, and the first detection module 9 is communicatively connected to the control module 8 via a wire. In other embodiments, the control module 8 and the first drive component 6 can also be wirelessly connected, and the first detection module 9 and the control module 8 can also be wirelessly connected, as long as communication can be achieved, this utility model does not impose any limitations on this.

[0054] It should also be noted that the control module 8 can be the vehicle computer of the vehicle 1000, or it can be a controller that communicates with the vehicle computer. This utility model does not limit this.

[0055] For example, based on the acquired air conditioning airflow demand signal, the control module 8 can control the first drive component 6 to operate, causing the seal 22 to move to adjust the opening area of ​​the vent 5. For instance, when the air conditioning airflow demand is large, the opening area of ​​the vent 5 is increased; when the air conditioning airflow demand is small, the opening area of ​​the vent 5 is decreased.

[0056] For example, the operating state of the first drive component 6 can be controlled according to the vehicle speed information. For instance, when the vehicle speed is not less than 80 km / h, the control module 8 controls the first drive component 6 to work, so that the seal 22 moves to block the ventilation opening 5, thereby reducing the wind resistance of the vehicle 1000.

[0057] Reference Figure 5 In some embodiments, the ventilation cover 2 is provided with a water tank 24, which is located on the side of the ventilation opening 5 facing the windshield 1; the vehicle 1000 also includes a second detection module that is communicatively connected to the control module 8. The second detection module is used to detect the water level of the water tank 24. The control module 8 is configured to control the seal 22 to move to avoid the ventilation opening 5 when the water level of the water tank 24 reaches a set condition.

[0058] Specifically, a water tank 24 is defined between the sixth plate portion 216 and the seventh plate portion 217.

[0059] In this embodiment of the utility model, in order to prevent the sealing element 22 from blocking the ventilation opening 5 and affecting the drainage of the water tank 4, a second detection module is set in the water tank 24 to ensure the reliability of the drainage of the water tank 4.

[0060] In some application scenarios, when vehicle 1000 is driving in the rain, when the second detection module detects that the water level in the water tank 24 has reached a set condition, the first drive component 6 controls the seal 22 to move to avoid the vent 5, so that water in the water tank 4 can flow through the air conditioning inlet 23 to the water tank 4 and be discharged through the water tank 4, ensuring the reliability of drainage from the water tank 4. When the second detection module detects that there is no water or the water level in the water tank 24 is low, the seal 22 can be in a state of blocking the vent 5 to reduce the wind resistance of vehicle 1000.

[0061] In some embodiments, the ventilation cover 2 includes a first drive assembly 6 for driving the seal 22 to move; in the front-rear direction, the cover body 21 covers the first drive assembly 6.

[0062] In the above technical solution, the cover plate body 21 covers the first drive component 6, avoiding the exposure of the first drive component 6, reducing the possibility of damage to the first drive component 6, and extending the service life of the ventilation cover plate 2.

[0063] Other configurations of the vehicle 1000 according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
