These illustrative expressions do not necessarily refer to the same embodiment, nor are they independent or alternative embodiments mutually exclusive with other embodiments. Where there is no conflict, the embodiments and features described in these embodiments can be combined in a suitable manner.

[0032] Figure 1 and Figure 2 This application provides a schematic diagram of the structure of an air intake grille assembly 100 at different angles, as shown in the embodiments. Figure 1 and Figure 2 As shown, this application embodiment provides an air intake grille assembly 100, including a grille frame 10, grille blades 20, a drive device 30, and a fairing 40.

[0033] The grille frame 10 serves as the mounting base for the grille blades 20 and the drive unit 30, and the grille frame 10 has an air intake for the grille blades 20 to open and close. When the grille frame 10 is installed in the front engine compartment of the vehicle, the grille frame 10 is connected to the radiator 200 at the front of the vehicle and the body structure.

[0034] As an example, the grille frame 10 includes a grille frame body 11 and two connecting feet 12. The lower part of the grille frame body 11 has two air intakes distributed along its width, each air intake being rectangular. The two connecting feet 12 are located at the bottom of the grille frame body 11 and are integrally connected to it. When the grille frame 10 is installed in the front engine compartment of a vehicle, the grille frame body 11 is located on the radiator 200 (see...). Figure 7The front side of the grille frame body 11 is connected to the radiator 200 by fasteners, and the top of the grille frame body 11 is connected to the upper bracket 1 of the radiator by fasteners (see...). Figure 7 The two connecting feet 12 are connected to the pedestrian leg guard beam 2 (see) via fasteners. Figure 7 )connect.

[0035] Multiple grille blades 20 are arranged in parallel at the air inlet, with adjacent grille blades 20 placed close together. Both ends of each grille blade 20 are rotatably connected to the grille frame 10. When any one of the blades flips, it can cause the adjacent blades to flip as well, thus allowing multiple grille blades 20 to flip together, thereby opening or closing the air inlet. One end of one of the grille blades 20 is provided with a drive shaft 25 for drive by the drive device 30.

[0036] As an example, such as Figure 3 As shown, each grille blade 20 includes a blade body 21, two mounting shafts 22, a crank portion 23, and a flange portion 24. The blade body 21 is an elongated structure with an airfoil-shaped cross-section. The leeward side of the blade body 21 (the surface facing the engine compartment when the air intake is closed) is concave and has multiple first reinforcing ribs. This structure reduces the weight of the blade body 21 while ensuring its structural strength. The two mounting shafts 22 are coaxially arranged at both ends of the blade body 21 and are rotatably connected to the grille frame 10. The crank portion 23 is located at one end of the blade body 21 and is used to contact the crank portion 23 of the adjacent grille blade 20 when the corresponding grille blade 20 rotates to achieve transmission. The flange portion 24 is arranged along the length of the blade body 21 and is used to block the blade body 21 of the adjacent grille blade 20 when the corresponding grille blade 20 is in the closed state, restricting its continued rotation. The flange portion 24 not only achieves the limiting function but also improves the sealing performance of the grille blade 20 in the closed state. When the flange 24 of the grid blade 20 just blocks the blade body 21 of the adjacent grid blade 20 (see...) Figure 3 When the air intake is closed, the air intake is opened when a long gap is formed between the blade bodies 21 of adjacent grille blades 20.

[0037] One of the grid blades 20 also includes a drive shaft portion 25, which replaces the mounting shaft portion 22 at one end of the grid blade 20, or is integrated with the mounting shaft portion 22.

[0038] As an example, the grille frame 10 is provided with two rectangular air inlets distributed along the width direction. Each air inlet is provided with five grille blades 20 distributed along the height direction. Among these five grille blades 20, the grille blade 20 located in the middle position is provided with a drive shaft portion 25 at one end. The crank portion 23 of the grille blade 20 is connected to the crank portion 23 of the adjacent grille blade 20, so that power can be transmitted to the other four grille blades 20 in sequence.

[0039] The drive unit 30 is mounted on the grille frame 10 and connected to the drive shaft 25 of the grille blade 20.

[0040] As an example, the drive unit 30 is an electric motor with a splined inner hole 31 at its output end. The motor is mounted on the inner surface of the grille frame body 11 (the side facing the front engine compartment of the vehicle) and is located between the two air intakes. The output end of the motor is connected to the drive shaft 25 of the grille blades 20 located in the middle of the two air intakes via a spline connection, thereby driving the five grille blades 20 on each side to rotate together, thus opening or closing the two air intakes.

[0041] like Figure 1 and Figure 4 As shown, the fairing 40 is connected to the front side of the grille frame 10, and its position corresponds to the air intake. The fairing 40 is used to guide airflow toward the air intake. When the fairing 40 is installed in the front engine compartment of the vehicle, the fairing 40 and the pedestrian leg protection beam 2 (see...) Figure 7 It comes into contact with the vehicle to absorb the impact energy when the vehicle collides.

[0042] As an example, the fairing 40 includes a fairing body 41 and a rubber cover 42. The fairing body 41 is made of metal and is mounted on the front side of the grille frame 10 using fasteners. The front edge of the fairing body 41 has multiple protruding connecting portions 411 spaced apart along its edge. The rear edge of the rubber cover 42 has multiple concave connecting portions 421 corresponding to these protruding connecting portions 411, and the rubber cover 42 is securely engaged with the front side of the fairing body 41 through a convex-concave fit. The front edge of the rubber cover 42 is an arc shape matching the shape of the pedestrian leg protection beam 2. When the fairing 40 is installed in the front engine compartment of the vehicle, the front edge of the rubber cover 42 abuts against the pedestrian leg protection beam 2. This structure can absorb some of the impact energy during a vehicle collision through the material properties of the rubber cover 42, especially in collisions between a vehicle and a pedestrian, effectively reducing injury to the pedestrian's legs and thus improving the vehicle's pedestrian protection performance.

[0043] It is conceivable that the positions of the convex connecting part 411 and the concave connecting part 421 can be interchanged to achieve the same effect.

[0044] Figure 5 This is a structural schematic diagram of a vehicle front-end module 1000 provided in an embodiment of this application. Figure 6 This is an exploded structural diagram of a vehicle front-end module 1000 provided in an embodiment of this application, as shown below. Figure 5 and Figure 6 As shown in the figure, this application embodiment also provides a vehicle front-end module 1000, including the above-mentioned air intake grille assembly 100, radiator 200, condenser 300, and fan 400. The grille frame 10, radiator 200, condenser 300, and fan 400 are sequentially connected and integrated into one unit.

[0045] Figure 7 This application provides a schematic diagram of the connection between a vehicle front-end module 1000 and the vehicle body structure, as shown in the embodiment of the present application. Figure 7 As shown, when the vehicle front module 1000 is installed in the front engine compartment of the vehicle, the vehicle front module 1000 is located between the rear side of the front bumper crossbeam 3 and the two front bumper longitudinal beams 4. The top of the vehicle front module 1000 is connected to the front bumper crossbeam 3 and the two front bumper longitudinal beams 4 through the upper bracket 1 of the radiator. The bottom of the vehicle front module 1000 is connected to the pedestrian leg protection beam 2, and the rubber cover 42 of the fairing 40 abuts against the pedestrian leg protection beam 2.

[0046] This application embodiment also provides a vehicle thermal management system, which includes the aforementioned vehicle front-end module 1000, and may also include an air conditioning system, a passenger compartment heating system, etc.

[0047] This application also provides a vehicle that includes the vehicle thermal management system described above.

[0048] In summary, the air intake grille assembly, vehicle front-end module, vehicle thermal management system, and vehicle provided in this application have the following advantages: the air intake grille assembly enables transmission through the contact of the crank portion during the flipping process, eliminating the need for additional transmission components and simplifying the transmission structure between the grille blades; when the grille blades are closed, the flange portion restricts the continued rotation of adjacent grille blades, ensuring the stability of the grille blade operation; the deflector not only optimizes the airflow direction and improves heat dissipation performance, but also, with at least a portion made of rubber, absorbs collision impact by abutting against the pedestrian leg protection beam during installation, thereby improving the vehicle's pedestrian protection performance. The air intake grille assembly can be integrated with the radiator, condenser, and fan to form a vehicle front-end module. This vehicle front-end module saves space and is easy to install while ensuring heat dissipation performance, making it suitable for various vehicle models and highly adaptable. The vehicle thermal management system and vehicle with this air intake grille assembly and vehicle front-end module inherit the advantages of the aforementioned air intake grille assembly and vehicle front-end module, possessing broad application prospects and market competitiveness.

[0049] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto.
