[0058] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0059] Please refer to Figures 1 to 9 , in order to achieve the above object, the present application provides an intake grille 10, and the intake grille 10 includes a frame 11 and grille vanes 12. The grille vanes 12 are rotatably connected to the frame 11, and the frame 11 and the grille vanes 12 enclose to form a first air inlet 13. Among them, the frame 11 is formed with a second air inlet 14, and the second air inlet 14 can communicate the external environment and the intake passage 24 of the engine of the fairing 20.

[0060] In the present application, by providing a second air inlet 14 in the frame 11 of the intake grille 10 that can communicate the external environment and the intake passage 24 of the engine of the fairing 20, the air flow in the environment can not only enter the vehicle front bumper assembly 100 through the first air inlet 13 formed by the grille vanes 12 after passing through the front bumper grille, but also pass through the second air inlet 14 and flow into the intake passage 24 of the engine after being guided by the fairing surface of the fairing 20, thereby effectively solving the technical problems of high engine intake temperature and insufficient power demand caused by insufficient intake air volume.

[0061] In some embodiments of the present application, the first air inlet 13 is also opposite to a part of the cooling module 50, and the second air inlet 14 is also opposite to another part of the cooling module 50. The airflow entering the air intake passage from the first air inlet 13 can dissipate heat from a part of the cooling module 50, and the airflow entering the air intake passage from the second air inlet 14 can also dissipate heat from another part of the cooling module 50, thereby increasing the air intake volume at the part of the cooling module 50 far from the first air inlet 13 and enhancing the cooling effect of the cooling module 50. In addition, the external airflow can flow into the cooling module through the first air inlet 13 and the second air inlet 14, which can improve the air intake uniformity.

[0062] In some embodiments of the present application, the opening degrees of both the first air inlet 13 and the second air inlet 14 can be adjusted. In this way, the amount of intake air can be adjusted according to the intake air demand to meet the different performance requirements of multiple systems.

[0063] In some embodiments of the present application, the air intake grille 10 further includes a driving member 15, and the opening degrees of the first air inlet 13 and the second air inlet 14 can be adjusted by the same or different driving members 15. In the present application, the driving member 15 is used to drive the grille blades 12 and drive corresponding elements (not shown in the figure) to control the opening degrees of the first air inlet 13 and the second air inlet 14, which is convenient and fast.

[0064] In this embodiment, the opening degrees of the first air inlet 13 and the second air inlet 14 are adjusted by different driving members 15.

[0065] In this embodiment, the air intake grille 10 further includes a connecting rod 19. The connecting rod 19 is connected to the frame 11 to divide the air intake grille 10 into multiple air intake areas. Both ends of the multiple grille blades 12 are respectively rotatably connected to the frame 11 and the connecting rod 19 in the corresponding air intake areas. The grille blades 12 can rotate driven by the driving member 15 to adjust the opening degree of the first air inlet 13. Among them, at least one driving member 15 is fixed to the connecting rod 19. The grille blades 12 in adjacent two air intake areas can be driven by the same driving member 15 or by different driving members 15.

[0066] In some embodiments of the present application, the frame 11 includes a first sub-frame 111. The first sub-frame 111 is disposed close to the fairing 20, and the second air inlet 14 is opened on the first sub-frame 111. In this way, the second air inlet 14 is disposed close to the fairing 20, and the external airflow can smoothly flow into the second sub-air intake passage 62 (see below) and the air intake passage 24 of the engine from the second air inlet 14, so as to enhance the cooling effect on the part of the cooling module 50 far from the first air inlet 13 and increase the air intake volume of the air intake passage of the engine, thereby effectively solving the technical problems of high engine intake air temperature and insufficient power demand caused by insufficient air intake volume.

[0067] In some embodiments of the present application, the frame 11 further includes a second sub-frame 112, a third sub-frame 113, and a fourth sub-frame 114, and the first sub-frame 111, the second sub-frame 112, the third sub-frame 113, and the fourth sub-frame 114 are connected end to end. The grille blades 12 are connected to the second sub-frame 112 and / or the fourth sub-frame 114.

[0068] In some embodiments of the present application, the second air inlet 14 includes a plurality of sub-air inlets 141 arranged at intervals. In this way, the intake air volume can be dynamically adjusted according to the vehicle driving state, avoiding unnecessary energy waste and improving the aerodynamic performance at the same time. In addition, this design can not only divide the air into multiple air streams, avoiding the air flow blockage and vortex phenomena that may occur in the single air inlet design, but also enable the air to enter the intake passage more evenly, reducing the local pressure difference, thereby improving the overall intake efficiency.

[0069] Among them, the number of the sub-air inlets 141 can be as large as possible on the premise of ensuring the structural strength of the intake grille 10.

[0070] In some embodiments of the present application, the plurality of sub-air inlets 141 extend along the first direction X and are arranged at intervals along the second direction Y, where the first direction X and the second direction Y intersect, and the "outer wall" on the same side of two adjacent sub-air inlets 141 refers to the first side 181 (see below) of the flange 18 (see below).

[0071] In some embodiments of the present application, the length of each sub-air inlet 141 in the first direction X is L, and 20 mm ≤ L ≤ 50 mm. In some embodiments of the present application, the width in the second direction Y is W, and 5 mm ≤ W ≤ 20 mm. In some embodiments of the present application, the distance between the outer walls on the same side of two adjacent sub-air inlets 141 is D, and 10 mm ≤ D ≤ 20 mm.

[0072] The above numerical values of L, W, and D can be satisfied simultaneously, or one or two of L, W, and D can be satisfied.

[0073] In this embodiment, the first direction X can be understood as the front-back direction, that is, the vehicle driving direction (including forward driving and backward driving), and the second direction Y can be understood as the left-right direction, that is, the vehicle width direction (the direction perpendicular to the vehicle driving direction). In other embodiments, the first direction X may also be different from the vehicle driving direction.

[0074] By limiting the length, width of the sub-air inlets 141 and the distance between adjacent sub-air inlets 141, the present application can ensure the structural strength of the frame 11 of the intake grille 10 while ensuring the intake air volume.

[0075] In this embodiment, the sub-air inlets 141 are arranged uniformly in the second direction.

[0076] In some embodiments of the present application, one end of the second air inlet 14 away from the first air inlet 13 has a flange 18, and the flange 18 is configured to strengthen the structural strength of the air intake grille 10 and have a flow guiding effect while ensuring that the effective air intake area remains unchanged.

[0077] In this embodiment, the flange 18 is arranged on the first sub-frame 111. The height, angle, and cross-sectional shape of the flange 18 are not limited as long as the structural strength and flow guiding effect of the entire air intake grille 10 can be strengthened while ensuring that the effective air intake area remains unchanged.

[0078] In this embodiment, the flange 18 includes a first side 181 and a second side 182 opposite to the first side 181. In other words, the first side 181 and the second side 182 are spaced apart in the second direction Y. The width W of each sub-air inlet 141 in the second direction Y can be understood as the distance between the first side 181 and the second side 182 of the same sub-air inlet 141. The distance D between the outer walls of the same side of two adjacent sub-air inlets 141 can be understood as the distance between the first sides 181 of two adjacent sub-air inlets 141.

[0079] In some embodiments of the present application, the sub-air inlets 141 include at least one of a runway shape, a circular shape, an oval shape, a rectangular shape, a rectangular shape, a cross-shaped through hole, etc. That is to say, the shape of the sub-air inlets 141 is not limited.

[0080] In some embodiments of the present application, the air intake grille 10 has a first air intake mode, a second air intake mode, a third air intake mode, and a fourth air intake mode. When the air intake grille 10 is in the first air intake mode, the first air inlet 13 is open and the second air inlet 14 is closed. When the air intake grille 10 is in the second air intake mode, the first air inlet 13 is closed and the second air inlet 14 is open. When the air intake grille 10 is in the third air intake mode, the first air inlet 13 is open and the second air inlet 14 is open. When the air intake grille 10 is in the fourth air intake mode, the first air inlet 13 is closed and the second air inlet 14 is closed. Designing the air intake grille 10 to have multiple air intake modes can flexibly control the amount of air intake according to the air intake requirements to meet the different performance requirements of multiple systems.

[0081] In some embodiments of the present application, when the vehicle has cooling system and air conditioning system intake requirements (i.e., when the air volume requirements of the cooling system and the air conditioning system are relatively large), the intake grille is in the first intake mode; when the vehicle has engine intake requirements (i.e., when the engine intake requirements are relatively large), the intake grille is in the second intake mode; when the vehicle has cooling system, air conditioning system and engine intake requirements (i.e., when the intake volume requirements of each system are relatively large in a high-temperature environment state of the whole vehicle), the intake grille is in the third intake mode; when the vehicle has no heat dissipation requirements (when the whole vehicle environment temperature is relatively low or the whole vehicle speed is relatively high but the heat dissipation requirements of each system are not large), the intake grille is in the fourth intake mode. By controlling the opening and closing states of the grille blades 12 and the sub-intake ports 141 by the controller, the optimal energy consumption of the whole vehicle can be achieved on the premise of simultaneously meeting the cooling requirements, air conditioning requirements and power requirements of the whole vehicle.

[0082] In some embodiments of the present application, when the intake grille is in the first intake mode, the grille blades include the first sub-intake mode, the second sub-intake mode and the third sub-intake mode; when the intake grille is in the first sub-intake mode, the grille blades are fully opened; when the intake grille is in the third sub-intake mode, the opening angle of the grille blades is a certain value between the fully closed and fully opened states of the grille blades; when the intake grille is in the third sub-intake mode, the opening angle of the grille blades changes dynamically. In this way, the opening degree of the first intake port 13 can be flexibly controlled according to the cooling requirements and the air conditioning requirements to meet different cooling requirements and air conditioning requirements.

[0083] In some embodiments of the present application, when the intake grille is in the second intake mode, there are infinite situations for the opening forms of the sub-intake ports 141 of the second intake port 14. Specifically, whether each sub-intake port 141 is opened and the opening angle size can be determined by the signal of the controller for controlling the opening degree of the second intake port 14 transmitted by the vehicle controller to the first sub-frame 111 (upper frame).

[0084] Please refer to Figures 1 - 9 , on the second aspect, the present application also provides a vehicle front bumper assembly 100, which includes an intake grille 10 and a deflector 20 located on one side of the intake grille 10. Among them, the deflector 20 has an intake passage 24 for the engine, and the second intake port 14 can communicate with the external environment and the intake passage 24 of the engine.

[0085] In this application, a second air inlet 14 is provided in the frame 11 of the intake grille 10, which can connect the external environment and the intake passage 24 of the engine in the fairing 20. After the air flow in the environment passes through the front bumper grille, it can not only enter the vehicle front bumper assembly 100 through the first air inlet 13 formed by the grille blades 12, but also enter through the second air inlet 14 and flow into the intake passage 24 of the engine after being guided by the guiding surface of the fairing 20, thereby effectively solving the technical problems of high engine intake air temperature and insufficient power demand caused by insufficient intake air volume.

[0086] In some embodiments of this application, the fairing 20 and the intake grille 10 overlap in the third direction Z. The third direction Z intersects the second direction Y and the first direction X respectively. In this embodiment, the first direction X, the second direction Y, and the third direction Z form a three-dimensional coordinate system. In addition, the intake grille 10 and the fairing 20 are installed separately in an up-and-down overlapping form, and the assembly is simple.

[0087] In some embodiments of this application, the fairing 20 further has a guiding cavity 25, and the second air inlet 14 can communicate with the guiding cavity 25. In this embodiment, when the second air inlet 14 is opened, the second air inlet 14 communicates with the guiding cavity 25, and when the second air inlet 14 is closed, the second air inlet 14 does not communicate with the guiding cavity 25. The guiding cavity 25 can guide the gas entering through the second air inlet 14 and can increase the air intake of the system.

[0088] In some embodiments of this application, the fairing 20 includes a guiding main body 201 and a convex part 202. The guiding cavity 25 is arranged in the guiding main body 201. The convex part 202 is fixedly connected to the guiding main body 201. The intake passage 24 of the engine is arranged in the convex part 202, and the guiding main body 201 overlaps with the fairing 20. In this way, the gas entering through the second air inlet 14 can flow into the guiding cavity 25 to enhance the cooling effect of the cooling module 50, and can also flow into the intake passage 24 of the engine to effectively solve the technical problems of high engine intake air temperature and insufficient power demand caused by insufficient intake air volume.

[0089] In some embodiments of this application, the opening direction of the second air inlet 14 faces the fairing 20.

[0090] In some embodiments of this application, in the setting direction of the fairing 20 and the intake grille 10, that is, in the third direction Z, the orthographic projection of the guiding main body 201 on the frame of the intake grille 10 covers the second air inlet 14. That is, one end of the second air inlet 14 is located in the guiding cavity 25. In this way, the air flow entering through the second air inlet 14 can directly enter the guiding cavity 25, the intake path is short, and the flow channel intake resistance is small.

[0091] In other embodiments, the extending direction of the second air inlet 14 may not be parallel to the third direction Z.

[0092] In some embodiments of the present application, the guiding main body portion 201 of the guiding cover 20 includes a first guiding surface 21, a second guiding surface 22, a third guiding surface 23 and a fourth guiding surface 26. The second guiding surface 22, the third guiding surface 23 and the fourth guiding surface 26 are respectively located on one side of the first guiding surface 21 and are respectively fixedly connected to the first guiding surface 21. One end of the first guiding surface 21 is separately arranged from the first sub-frame 111, and the convex portion 202 is connected to the second guiding surface 22 and the fourth guiding surface 26. The shapes of the respective guiding surfaces are not specifically required.

[0093] In some embodiments of the present application, one end of the first guiding surface 21 may be in contact with the first sub-frame 111 or may not be in contact.

[0094] In some embodiments of the present application, the shapes of the respective guiding surfaces of the guiding cover 20 may be other shapes such as a plane, an inclined plane, an arc surface, etc. under the conditions of ensuring the process, assembly and sealing.

[0095] In this embodiment, the first guiding surface 21, the second guiding surface 22, the third guiding surface 23 and the fourth guiding surface 26 are respectively a front guiding surface, a left guiding surface, a right guiding surface and an upper guiding surface. That is, one end of the front guiding surface is separately arranged from the first sub-frame 111, and the convex portion 202 is connected to the left guiding surface and the upper guiding surface.

[0096] In some embodiments of the present application, the vehicle front bumper assembly 100 further includes a bumper beam 30 and a front end module 40. The frame 11 of the intake grille 10 is respectively fixedly connected to the bumper beam 30 and the front end module 40, so as to ensure the installation stability of the intake grille 10. The assembly method of the intake grille 10 is simple and can be completed without hoisting the vehicle to a high working position.

[0097] In some embodiments of the present application, the first sub-frame 111 of the intake grille 10 is fixedly connected to the bumper beam 30, and the second sub-frame 112, the third sub-frame 113 and the fourth sub-frame 114 of the intake grille 10 are respectively fixedly connected to the front end module 40.

[0098] In some embodiments of the present application, the guiding cover 20 is respectively fixedly connected to the bumper beam 30 and the front end module 40, so as to ensure the installation stability of the guiding cover 20. The assembly method of the guiding cover 20 is simple and can be completed without hoisting the vehicle to a high working position.

[0099] In some embodiments of the present application, the first guiding surface 21 of the guiding cover 20 is fixedly connected to the bumper beam 30, and the second guiding surface 22, the third guiding surface 23 and the fourth guiding surface 26 are respectively fixedly connected to the front end module 40.

[0100] In some embodiments of the present application, the vehicle front bumper assembly 100 further includes a front bumper (not shown in the figure). The anti-collision beam 30 is located on the side of the air deflector 20 and the intake grille 10 away from the front bumper. That is, the integrated air deflector 20 is located in front of the anti-collision beam 30 and overlaps with the first sub-frame 111 of the intake grille 10 below. In this way, the distance between the first air guiding surface 21 (front air guiding surface) of the air deflector 20 and the cooling module 50 increases, the volume of the entire intake passage 60 increases, the intake resistance decreases, which is conducive to the diffusion and flow of air upward, and has a good cooling effect.

[0101] In some embodiments of the present application, the vehicle front bumper assembly 100 further includes a cooling module 50. The cooling module 50 is fixedly connected to the front end module 40 and faces the intake grille 10 and the air deflector 20. In this way, the air flow in the environment can enter the intake passage 60 from the first air inlet 13 after passing through the front bumper grille and flow into the part of the cooling module 50 opposite to the intake grille 10. The air flow in the environment can also enter the intake passage 60 from the second air inlet 14 after passing through the front bumper grille and flow into the part of the cooling module 50 away from the intake grille 10 and the intake passage 24 of the engine after being guided by the air guiding surface of the air deflector 20, thereby effectively solving the technical problems of poor cooling effect caused by less intake air volume at the part of the cooling module 50 far from the first air inlet 13, high intake air temperature of the engine, insufficient intake air volume, and inability to meet the power demand.

[0102] In some embodiments of the present application, the intake grille 10, the air deflector 20 and the front end module 40 enclose to form an intake passage 60. The intake passage 60 includes a first sub-intake passage 61 and a second sub-intake passage 62. The air inlet of the first sub-intake passage 61 can communicate with the first air inlet 13 of the intake grille 10, and the air outlet of the first sub-intake passage 61 contacts a part of the cooling module 50. The air inlet of the second sub-intake passage 62 communicates with the second air inlet 14 of the intake grille 10, and the air outlet of the second sub-intake passage 62 communicates with the intake passage 24 of the engine and contacts another part of the cooling module 50. In this way, the air flow in the environment can enter the first sub-intake passage 61 from the first air inlet 13 after passing through the front bumper grille and flow into the part of the cooling module 50 facing the intake grille 10. The air flow in the environment can enter the second sub-intake passage 62 from the second air inlet 14 after passing through the front bumper grille and flow into the intake passage 24 of the engine after being guided by the air guiding surface of the air deflector 20, thereby effectively solving the technical problems of high intake air temperature of the engine, insufficient intake air volume, and inability to meet the power demand.

[0103] Specifically, when the first air inlet 13 and the second air inlet 14 are opened simultaneously, the entire vehicle front bumper assembly 100 has two air inlet channels, namely the first sub-air inlet channel 61 and the second sub-air inlet channel 62. For the air flow into the vehicle, a part of the air passes through the first air inlet 13 (the grille vane 12) and then flows into the cooling module 50 through the first sub-air inlet channel 61, and another part of the air passes through the second air inlet 14 and then flows into the upper middle part of the cooling module 50 and the air inlet channel 24 of the engine through the second sub-air inlet channel 62. With this structure, the following technical effects are achieved: First, the volume of the air inlet channel 60 is increased, and the air intake resistance of the system is reduced. At the same vehicle speed and fan speed, more effective air flow flows into the air inlet channel 60 from the outside; Second, the air intakes of the first sub-air inlet channel 61 and the second sub-air inlet channel 62 can both flow into the cooling module 50, improving the air intake uniformity and enhancing the heat exchange amount and heat exchange efficiency of the cooling module 50; Third, the air intake of the second sub-air inlet channel 62 meets the air intake requirements of the engine, effectively reducing the air intake temperature of the original engine air inlet and ensuring the power performance of the engine; Fourth, the second air inlet 14 effectively utilizes the ineffective area of the front bumper facing the bumper beam 30, increasing the air intake volume of the system.

[0104] Specifically, when the grille vane 12 (the first air inlet 13) of the air intake grille 10 is closed, the entire vehicle front bumper assembly 100 has only the sole second sub-air inlet channel 62. For the air flow into the vehicle, after passing through the second air inlet 14 above the air intake grille 10, it flows into the air inlet channel 24 of the engine through the second sub-air inlet channel 62, ensuring the power performance when the vehicle is in the engine drive mode.

[0105] In some embodiments of the present application, the air outlet of the second sub-air inlet channel 62 faces another part of the cooling module 50. In this way, the air flow in the environment can enter the second sub-air inlet channel 62 from the second air inlet 14 after passing through the front bumper grille, and after being guided by the guiding surface of the guiding cover 20, it flows into that part of the cooling module 50 far from the air intake grille 10, thus effectively solving the technical problem of poor cooling effect caused by the small air intake volume at the part of the cooling module 50 far from the first air inlet 13.

[0106] In some embodiments of the present application, the bumper beam 30 is located inside the air inlet channel 60. Specifically, the air intake grille 10 and the guiding cover 20 are installed in a split manner with upper and lower lapping in front of the bumper beam 30, and the bumper beam 30 is wrapped inside the entire air inlet channel 60. Compared with the design where the bumper beam is located in front of the guiding cover, in this case, the bumper beam 30 is arranged inside the air inlet channel 60, that is, behind the guiding cover 20. The distance between the first guiding surface 21 of the guiding cover 20 and the cooling module 50 is increased, the volume of the entire air inlet channel 60 is increased, and the air intake resistance is decreased, thus effectively solving the above problems that the volume of the air inlet channel is small, the resistance is large, which is not conducive to the diffusion and flow of the air flow upward, and the cooling effect is poor caused by the bumper beam being located in front of the guiding cover.

[0107] In some embodiments of the present application, the vehicle front bumper assembly 100 further includes a plug block 70. The plug block 70 is used to seal the gap between the intake grille 10, the deflector 20, the bumper beam 30 and the cooling module 50, and is located on the side of the bumper beam 30 away from the vehicle's front bumper. Since the distance between the intake grille 10 and the deflector 20 is relatively large, the plug block 70 can not only play a connecting role but also play a certain sealing role.

[0108] In some embodiments of the present application, the upper end of the plug block 70 is connected to the deflector 20, the lower end of the plug block 70 is connected to the intake grille 10, the front end of the plug block 70 is connected to the bumper beam 30, and the rear end of the plug block 70 is connected to the cooling module 50.

[0109] In some embodiments of the present application, the intake grille 10 is respectively sealed with the front bumper, the bumper beam 30, the cooling module 50 and the plug block 70 through a first seal 81.

[0110] In some embodiments of the present application, the deflector 20 is respectively sealed with the intake grille 10, the bumper beam 30, the front end module 40, the cooling module 50 and the plug block 70 through a second seal 82.

[0111] Among them, through the action of the first seal 81, the second seal 82 and the plug block 70, good sealing can be achieved between the various components of the vehicle front bumper assembly 100, reducing the intake air volume loss flowing from the front bumper into the cooling module 50 and the intake passage 24 of the engine, and reducing the air volume of the high-temperature air in the front compartment flowing back into the intake passage 60.

[0112] In some embodiments of the present application, the vehicle front bumper assembly 100 further includes a front bumper grille (not shown in the figure), which is located on one side of the intake grille 10. Airflow can enter the first intake port 13 and the second intake port 14 through the front bumper grille.

[0113] In some embodiments of the present application, the vehicle front bumper assembly 100 further includes two energy absorption boxes 90. One ends of the two energy absorption boxes 90 are respectively connected to the two ends of the bumper beam 30, and the other ends are connected to the vehicle's longitudinal beam, playing a role in absorbing collision energy.

[0114] Please refer to Figure 10 , Thirdly, the present application further provides a vehicle 1000, which includes the intake grille 10 or the vehicle front bumper assembly 100.

[0115] In some embodiments of the present application, the vehicle 1000 further includes a controller 200, and the controller 200 is configured to control the driving member 15 to adjust the opening degrees of the first intake port 13 and the second intake port 14.

[0116] In some embodiments of the present application, the vehicle 1000 further includes a sensor 300, which is configured to obtain the demand parameters of the vehicle 1000. The controller 200 is further configured to obtain the intake demand of the current vehicle according to the demand parameters, and control the opening degrees of the first intake port 13 and the second intake port 14 according to the intake demand required by the current vehicle.

[0118] The first sub-controller 301 and the second sub-controller 302 are configured to control the driving member 15 to adjust the opening degrees of the first intake port 13 and the second intake port 14 according to the instructions issued by the third sub-controller 303.

[0119] The third sub-controller 303 is used to obtain the intake demand of the current vehicle according to the demand parameters, and send instructions to the first sub-controller 301 and the second sub-controller 302 according to the intake demand required by the current vehicle. Here, the instructions are the intake mode required by the current vehicle and the corresponding opening degrees of the first intake port 13 and the second intake port 14.

[0120] In other embodiments, the controller 200 may only have a single vehicle controller.

The control method includes: Step S1: Obtain the demand parameters of the vehicle; Step S2: Obtain the intake demand of the current vehicle according to the demand parameters; and Step S3: Control the opening degrees of the first intake port 13 and the second intake port 14 according to the intake demand of the current vehicle.

[0123] Among them, the cooling state parameters, air conditioning state parameters, and power state parameters can be characterized by parameters such as vehicle speed, outside temperature, inside temperature, water temperature, air conditioning pressure, intake pressure, etc.

[0125] Among them, the "current vehicle state" in step S21 may include the current cooling, power, and energy consumption status of the vehicle, etc. The "demand for the current vehicle state" in step S22 may include the cooling, power, and energy consumption demands of the current vehicle state.

[0126] In some embodiments of the present application, when the current vehicle has intake demands for the cooling system and the air conditioning system, it is determined that the intake grille 10 is in the first intake mode.

When the current vehicle has a heat dissipation demand, it is determined that the intake grille 10 is in the fourth intake mode. By controlling the opening and closing states of the grille blades 12 and the sub-intake ports 141 by the controller, the optimal energy consumption effect of the whole vehicle can be achieved on the premise of simultaneously meeting the cooling demand, air conditioning demand, and power demand of the whole vehicle.

Designing the intake grille 10 to have multiple intake modes can flexibly control the amount of intake air according to the intake demand to meet the different performance requirements of multiple systems.

[0128] In some embodiments of the present application, when the intake grille 10 is in the first intake mode, the grille blades 12 include a first sub-intake mode, a second sub-intake mode, and a third sub-intake mode. When the intake grille 10 is in the first sub-intake mode, control the grille blades 12 to open completely.
