Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a vehicle airflow system and a vehicle. Background Technology

[0002] When a vehicle is in motion, the airflow in front of the vehicle is diverted to the top, sides, and bottom of the vehicle after contacting the vehicle's surface, creating wind resistance in multiple directions. Wind resistance is one of the key factors affecting the vehicle's range. In particular, the front of the vehicle is equipped with structures such as the front bumper, fog lights, and continuous lights. Due to the influence of their shape and installation structure, the diversion of airflow in front of the vehicle is aggravated, which in turn increases the drag coefficient and affects the user experience. Summary of the Invention

[0003] The purpose of this invention is to provide a vehicle airflow system and vehicle that can effectively reduce the area of ​​the high-pressure zone at the front of the vehicle, guide most of the airflow at the front of the vehicle to the upper surface of the engine hood, and achieve airflow guidance through the upper surface of the engine hood. This effectively avoids the problem of increased drag coefficient caused by the airflow at the front of the vehicle being diverted to various directions, thereby improving the vehicle's range performance.

[0004] This invention provides a vehicle airflow system, comprising: At least one air intake duct is located above the center light, and at least one of said air intake ducts is formed by the connection between the center light and the front bumper trim. At least one air vent is located at the rear of the front bumper trim and in front of the hood. And at least one connecting channel, located on the front bumper trim, the connecting channel being used to connect at least one of the air intake channels and at least one of the air outlet channels. The airflow at the front of the vehicle enters at least one of the connecting channels through at least one of the air intake channels and flows out along the upper surface of the engine hood through at least one of the air outlet channels.

[0005] In one embodiment, the diameter of the front portion of at least one of the air inlet channels is larger than the diameter of the rear portion, so as to form a first flared area at the front portion of at least one of the air inlet channels; or, the diameter of the front portion of at least one of the air inlet channels is smaller than the diameter of the rear portion, so as to form a second flared area at the rear portion of at least one of the air inlet channels.

[0006] In one embodiment, the diameter of the front portion of at least one of the air outlet channels is larger than the diameter of the rear portion, so as to form a third flared region at the front portion of at least one of the air outlet channels; or, the diameter of the front portion of at least one of the air outlet channels is smaller than the diameter of the rear portion, so as to form a fourth flared region at the rear portion of at least one of the air outlet channels.

[0007] In one embodiment, the rear end of the lower channel wall of at least one of the air outlet channels is higher than the front end of the upper surface of the engine hood, or the rear end of the lower channel wall of the air outlet channel is flush with the front end of the upper surface of the engine hood.

[0008] In one embodiment, at least one of the air intake channels and / or at least one of the connecting channels is provided with a baffle, the baffle extending along the left-right direction of the vehicle, and two or more baffles being spaced apart along the front-rear direction of the vehicle.

[0009] In one embodiment, the front bumper trim includes a first trim panel and a second trim panel, which are connected vertically. The front part of the first trim panel cooperates with the center light to form at least one air intake channel. The first trim panel and the second trim panel cooperate to form at least one air outlet channel and at least one connecting channel.

[0010] In one embodiment, the upper surface of the center lamp, the upper surface of the second trim panel, and the upper surface of the hood transition naturally in the front-rear direction.

[0011] In one embodiment, at least one partition is provided between the first trim panel and the second trim panel. The at least one partition extends in the vertical direction, and the upper and lower ends of the at least one partition are respectively connected to the first trim panel and the second trim panel. When there are two or more partitions, the two or more partitions are distributed at intervals in the left and right direction of the vehicle.

[0012] In one embodiment, the front end of the partition is recessed rearward relative to the first trim panel so that the first trim panel and the center light cooperate to form an air intake channel, and / or the rear end of the partition is recessed forward relative to the first trim panel so that the first trim panel and the second trim panel cooperate to form an air outlet channel.

[0013] The present invention also proposes a vehicle including the aforementioned vehicle airflow system.

[0014] The beneficial effects of this invention are as follows: During vehicle operation, the airflow at the front of the vehicle enters the connecting channel at the junction of the center headlight and the front bumper trim, and flows out through the air outlet at the front of the hood. The outflowing airflow can flow along the upper surface of the hood, guiding most of the airflow at the front of the vehicle to the upper surface of the hood. This effectively avoids the problem of the airflow at the front of the vehicle being diverted to various directions, which would increase the drag coefficient. The vehicle airflow system proposed in this invention can effectively reduce the area of ​​the high-pressure zone at the front of the vehicle, allowing the airflow at the front of the vehicle to be unaffected by the shape and installation of the center headlights and front bumper trim. By placing the air outlet duct in front of the hood, the airflow at the front of the vehicle can be efficiently guided through the cooperation of the air intake duct, connecting duct, air outlet duct and hood, effectively reducing air resistance during vehicle operation, which is beneficial to improving the vehicle's range performance, and ensuring the structural stability of the various components at the front of the vehicle, which is conducive to the diverse styling design of the front of the vehicle.

[0027] Combination Figures 1 to 3 The vehicle airflow system proposed in this invention includes: At least one air intake duct 10 is located above the center light 100, and the at least one air intake duct 10 is formed by connecting the center light 100 and the front bumper trim 200. At least one air vent 20 is located at the rear of the front bumper trim 200 and in front of the hood 300. And at least one connecting channel 30, located on the front bumper trim 200, the connecting channel 30 being used to connect at least one air intake channel 10 and at least one air outlet channel 20. The airflow at the front of the vehicle enters at least one connecting channel 30 through at least one air intake channel 10 and flows out along the upper surface of the engine hood 300 through at least one air outlet channel 20.

[0028] During vehicle operation, the airflow at the front of the vehicle enters the connecting channel 30 through the air intake channel 10 at the connection between the center headlight 100 and the front bumper trim 200, and flows out through the air outlet channel 20 at the front of the hood 300. The outflowing airflow can flow along the upper surface of the hood 300, which can guide most of the airflow at the front of the vehicle to the upper surface of the hood 300. The airflow is effectively guided by the upper surface of the hood 300, which effectively avoids the problem of the airflow at the front of the vehicle being diverted to various directions, thus increasing the drag coefficient. The vehicle airflow system proposed in this invention can effectively reduce the area of ​​the high-pressure zone at the front of the vehicle, allowing the airflow at the front of the vehicle to be unaffected by the shape and installation of the center headlight 100 and the front bumper trim 200. The air outlet duct 20 is positioned in front of the hood 300. With the cooperation of the air inlet duct 10, connecting duct 30, air outlet duct 20 and hood 300, the airflow at the front of the vehicle can be efficiently guided, effectively reducing air resistance during vehicle operation, which is beneficial to improving the vehicle's range performance, and ensuring the structural stability of the various components at the front of the vehicle, which is conducive to diverse styling designs for the front of the vehicle.

[0029] In one embodiment, reference is made to Figure 3 At least one air intake duct 10 is configured such that the diameter of the front opening is larger than the diameter of the rear opening, so as to form a first flared area at the front of the at least one air intake duct 10. The first flared area facilitates the entry of airflow from the front of the vehicle into the air intake duct 10, thereby improving air intake efficiency.

[0030] In one embodiment, at least one air inlet channel 10 is configured such that the diameter of its front portion is smaller than that of its rear portion, forming a second flared region at the rear of the at least one air inlet channel 10. This second flared region facilitates the guidance of airflow into the connecting channel 30, thereby improving airflow guidance efficiency. In another embodiment, at least one air outlet channel 20 has a larger diameter at its front portion than its rear portion, forming a third flared region at the front of the at least one air outlet channel 20. This third flared region facilitates the entry of airflow from the connecting channel 30 into the air outlet channel 20 and its discharge through the air outlet channel 20, thereby improving airflow discharge efficiency.

[0031] In one embodiment, the diameter of the front portion of at least one air outlet duct 20 is smaller than the diameter of the rear portion, forming a fourth flared region at the rear of the at least one air outlet duct 20. This fourth flared region facilitates the discharge of airflow within the air outlet duct 20, thereby improving the efficiency of airflow discharge. In one embodiment, as... Figure 3As shown, the rear end of the lower channel wall of at least one air outlet duct 20 is higher than the front end of the upper surface of the engine hood 300. With this configuration, the airflow discharged through the air outlet duct 20 can be partially guided along the upper surface of the engine hood 300, while the rest is dispersed into the air. This can divert the airflow discharged from the air outlet duct 20, thereby preventing excessive airflow from converging on the upper surface of the engine hood 300. Alternatively, the rear end of the lower channel wall of at least one air outlet duct 20 is flush with the front end of the upper surface of the engine hood 300, thereby effectively guiding the airflow discharged from the air outlet duct 20 to the upper surface of the engine hood 300, allowing the airflow to be efficiently guided through the upper surface of the engine hood 300, resulting in a better guiding effect.

[0032] In one embodiment, combined with Figure 3 and Figure 4 The air intake channel 10 or the connecting channel 30 is provided with a spoiler 11. The spoiler 11 extends along the left and right direction of the vehicle. Two or more spoilers 11 are distributed at intervals along the front and rear direction of the vehicle. The spoiler 11 can play a good role in guiding the airflow, so that the airflow can smoothly transition within the front bumper trim 200, avoid the generation of separation vortices and turbulence, and help improve the airflow efficiency and the vehicle's NVH (Noise, Vibration and Harshness) performance.

[0033] In one embodiment, combined with Figure 3 and Figure 4 The front bumper trim 200 includes a first trim panel 201 and a second trim panel 202. The first trim panel 201 and the second trim panel 202 are connected in the vertical direction. The front part of the first trim panel 201 cooperates with the center headlight 100 to form at least one air intake channel 10. The rear part of the first trim panel 201 cooperates with the rear part of the second trim panel 202 to form at least one air outlet channel 20. The middle part of the first trim panel 201 and the middle part of the second trim panel 202 cooperate to form at least one connecting channel 30.

[0034] In an example scheme, such as Figure 3 As shown, the upper surface of the center lamp 100 forms the lower channel wall of the air intake channel 10, and the upper surface of the second trim panel 202 forms the lower channel wall connecting the channel 30 and the air outlet channel 20. The upper surfaces of the center lamp 100, the second trim panel 202, and the engine hood 300 transition naturally in the front-to-back direction and are roughly arc-shaped. This arrangement allows the airflow to flow smoothly to the engine hood 300 without generating wind noise.

[0035] In one example scheme, combined Figure 1 and Figure 3The front end of the first trim panel 201 is configured to be offset rearward relative to the front end of the center lamp 100, thereby forming a relatively large flared area at the front of the air intake channel 10. This flared area facilitates the entry of airflow from the front of the vehicle into the air intake channel 10, thereby improving airflow efficiency, effectively reducing the area of ​​the high-pressure zone at the front of the vehicle, and reducing the probability of airflow diversion at the front of the vehicle.

[0036] In an example scheme, such as Figure 1 As shown, at least one partition 203 is provided between the first trim panel 201 and the second trim panel 202. The at least one partition 203 extends in the vertical direction, and the upper and lower ends of the at least one partition 203 are respectively connected to the first trim panel 201 and the second trim panel 202. When the number of partitions 203 is two or more, the two or more partitions 203 are distributed at intervals in the left and right direction of the vehicle.

[0037] The partition 203 enables the first trim panel 201 to have a good floating effect when the first trim panel 201 and the second trim panel 202 are connected, taking into account both the function of reducing wind resistance and the function of the device, and improving the aesthetics and design of the vehicle. At the same time, the partition 203 can play a separating role, thereby forming at least one air intake channel 10, at least one air outlet channel 20 and at least one connecting channel 30 mentioned above.

[0038] For example, the front and rear dimensions of the separator 203 are the same as those of the first trim panel 201, thereby enabling the separation to form the same number of at least one air inlet channel 10, at least one air outlet channel 20 and at least one connecting channel 30.

[0039] For example, the front-to-back dimensions of the partition 203 are smaller than the front-to-back dimensions of the first trim panel 201 and the second trim panel 202. The front end of the partition 203 is recessed rearward relative to the first trim panel 201 so that the first trim panel 201 and the center light 100 cooperate to form an air intake channel 10, and / or the rear end of the partition 203 is recessed forward relative to the first trim panel 201 so that the first trim panel 201 and the second trim panel 202 cooperate to form an air outlet channel 20.

[0040] More specifically, the separator 203 is located in the middle of the first trim panel 201 in the front-rear direction, and only serves to separate at least two connecting channels 30 within the front bumper trim 200, but is not used to separate the air intake channel 10 and the air outlet channel 20. The at least two connecting channels 30 are connected to one air intake channel 10 and one air outlet channel 20.

[0041] This configuration allows for a larger air intake area to be formed at the front of the vehicle through an air intake duct 10, which facilitates the entry of airflow from the front of the vehicle into the air intake duct 10, thereby improving air intake efficiency, effectively reducing the area of ​​the high-pressure zone at the front of the vehicle, and reducing the probability of airflow diversion at the front of the vehicle. The airflow entering the air intake duct 10 can be diverted through at least two connecting channels 30, thereby avoiding wind noise problems caused by excessively large cavity areas of the connecting channels 30. The airflow within at least two connecting channels 30 converges at an air outlet duct 20, thereby achieving efficient air outlet.

[0042] For example, the first trim panel 201, the partition 203, and the second trim panel 202 are integrally injection molded, thereby enabling the connection channel 30 to be integrated inside the front bumper trim 200, which is convenient to manufacture and does not require additional assembly steps.

[0043] In an example scheme, such as Figure 3 As shown, the lower end of the first decorative panel 201 is connected to a decorative panel frame 204 and a supporting base plate 205. The decorative panel frame 204 is connected between the first decorative panel 201 and the supporting base plate 205 to provide structural support for the first decorative panel 201 and ensure the structural stability of the first decorative panel 201.

[0044] For example, the first decorative panel 201, the decorative panel frame 204 and the supporting base plate 205 are connected by structural adhesive or by welding, so as to reduce the overall weight while ensuring structural stability.

[0045] For example, the aforementioned spoiler 11 protrudes from the lower surface of the first decorative panel 201, and more specifically, from the lower surface of the supporting base plate 205.

[0046] Furthermore, the spoiler 11 is integrally formed with the lower surface of the support base plate 205.

[0047] In one example, the front bumper trim 200 is made of engineering plastic to reduce overall weight while ensuring structural stability and effectively reducing investment costs.

[0048] In one example scheme, combined Figure 3 and Figure 4 The front part of the second trim panel 202 is connected to the headlight assembly via a connector 206. The headlight assembly includes at least a center lamp 100 and a headlight 400. The connector 206 is a snap-fit ​​component. The front part of the second trim panel 202 and the headlight assembly are provided with slots to cooperate with the connector 206 to achieve connection and fixation. The connection method is simple and easy to install.

[0049] In an example scheme, such as Figure 3As shown, the rear of the second trim panel 202 is provided with a flange 207. The flange 207 extends downward and backward relative to the second trim panel 202 and extends to the lower front end of the hood 300. The flange 207 is used to connect with the front frame of the vehicle, thereby fixing the second trim panel 202.

[0050] For example, the flange 207 has a fixing hole 208, and the front frame has a matching hole that mates with the fixing hole 208. The fixing hole 208 and the matching hole mate and are connected by fasteners, which can be screws or bolts.

[0051] Understandably, the center lamp 100 of the present invention refers to a structure located in the middle of the front of a vehicle that has at least a lighting function. It can be a structure composed of a display screen that has both lighting and display functions, or a structure composed of a lamp panel that has both lighting and pattern display and text display functions.

[0052] The present invention also proposes a vehicle including the aforementioned vehicle airflow system.

[0053] The vehicle with a vehicle air guiding system proposed in this invention, by setting an air intake channel 10, a connecting channel 30 and an air outlet channel 20 that run through the front bumper trim 200, can concentrate the airflow at the front of the vehicle to enter and pass through the front bumper trim 200, thereby effectively reducing the high pressure area at the front of the vehicle, reducing the air resistance coefficient, and effectively ensuring fuel economy or pure electric range performance.

[0054] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
