The FEM integrates components such as engine compartment locks, radiators, condensers, intercoolers, crash beams, bumpers, sensors, headlights, bumpers, and even fenders through a specialized framework.

[0044] The vehicle's front-end module also includes an active grille shutter, which can change the opening and closing of the grille to control the intake volume and wind resistance, thereby improving fuel economy and quickly reaching the engine's optimal operating temperature.

[0045] like Figure 1A As shown in Figures 1B, 2A, and 3, the active air intake grille 900 includes a main frame 1, a first blade 2, a second blade 5, a connecting rod 3, and a drive assembly 4. The main frame 1 includes a frame body 10. The frame body 10 has vents 1a that allow airflow. Multiple vents 1a can be provided as needed, and correspondingly, the first blade 2 and the second blade 5 can also form multiple blade groups, each disposed in one of the multiple vents 1a. The drive assembly 4 is mounted on the main frame 1.

[0048] refer to Figure 10 , 11 The first blade 2 is configured to rotate along a first rotation direction S1 from the first blade position B1 to the second blade position B2, and the second blade 5 is configured to rotate along a third rotation direction S3 from the third blade position B3 to the fourth blade position B4, so as to regulate the airflow through the vent 1a. Figure 10 , 11In this configuration, the first blade 2 is located at position B1, and the second blade 5 is located at position B3; these positions B1 and B3 are also referred to as the closed position or the 0° position. In embodiments not shown, the first blade position B1 and the third blade position B3 can also be positions other than the 0° position. At the 0° position, blade 2 closes the air vent 1a. Figure 11 In the diagram, the first blade 2 is located at the second blade position B2, and the second blade 5 is located at the fourth blade position B4. Specifically, the first blade 2 rotates by an angle α from the first blade position B1 along the first rotation direction S1 to reach the second blade position B2, and the second blade 5 rotates by an angle β from the third blade position B3 along the third rotation direction S3 to reach the fourth blade position B4. Figure 11 In this context, the angles α and β are both 45°, therefore the second blade position B2 and the fourth blade position B4 are also referred to as the 45° position. In embodiments not shown, the second blade position B2 can also be any position other than the 45° position.

[0049] like Figure 10 , 11 As shown, link 3 has a first link wall 3a and a fifth link wall 3g; drive assembly 4 drives link 3 to move relative to main frame 1 along a first translational direction T1, so that the first link wall 3a pushes the first blade connecting part 21, thereby causing the first blade 2 to rotate along a first rotational direction S1, and the fifth link wall 3g pushes the second blade connecting part 51, thereby causing the second blade 5 to rotate along a third rotational direction S3; during the process of the first blade 2 rotating from the first blade position B1 to the second blade position B2 along the first rotational direction S1, the first blade connecting part 21 slides along the first link wall 3a from the first link position R1 to the second link position R2 along the first sliding direction G1; and during the process of the second blade 5 rotating along the third rotational direction S3 from the third blade position B3 to the fourth blade position B4, the second blade connecting part 51 slides along the fifth link wall 3g from the ninth link position R9 to the tenth link position R10 along the fifth sliding direction G5. The first rotational direction S1 is opposite to the third rotational direction S3. The fifth sliding direction G5 is opposite to the first sliding direction G1.

[0050] exist Figure 10 In the middle, the first blade 2 is located at the first blade position B1, the second blade 5 is located at the third blade position B3, the first blade connecting part 21 is located at the first link position R1, the second blade connecting part 51 is located at the ninth link position R9, and the link 3 is located at the first frame position F1; Figure 11In the middle, the first blade 2 is located at the second blade position B2, the second blade 5 is located at the fourth blade position B4, the first blade connecting part 21 slides to the second link position R2, the second blade connecting part 51 slides to the tenth link position R10, and the link 3 is located at the second frame position F2.

[0051] In the above embodiments, the translational movement of the connecting rod 3 relative to the main frame 1 can drive the rotation of the first blade 2 and the second blade 5. Therefore, the movement space required for the connecting rod 3 is small, and the active air intake grille assembly provided by the present invention has the advantage of a compact structure. Furthermore, the different rotation directions of the first blade 2 and the second blade 5 allow them to form a certain angle, thereby enabling the airflow guided by the first blade 2 and the second blade 5 to form a certain angle. This helps the airflow guided by the first blade 2 and the second blade 5 to converge or expand. When the airflow converges, it can focus on a specific area of ​​a component, such as the upper or lower part of a radiator. When the airflow expands, it can cover more components or a larger area of ​​a component.

[0052] like Figure 12 , 13 As shown, the connecting rod 3 also has a second connecting rod wall 3b and a sixth connecting rod wall 3h; the driving assembly 4 is used to drive the connecting rod 3 to move relative to the main frame 1 along a second translational direction T2, so that the second connecting rod wall 3b and the sixth connecting rod wall 3h respectively drive the first blade connecting part 21 and the second blade connecting part 51 to move, thereby driving the first blade 2 and the second blade 5 to rotate along a second rotational direction S2 and a fourth rotational direction S4 respectively, wherein the second rotational direction S2 is opposite to the first rotational direction S1, the second translational direction T2 is opposite to the first translational direction T1; the second rotational direction S2 is opposite to the fourth rotational direction S4; and the fourth rotational direction S4 is opposite to the third rotational direction S3.

[0053] like Figure 13 As shown, during the process of the first blade 2 rotating from the second blade position B2 to the first blade position B1 along the second rotation direction S2, the first blade connecting part 21 slides from the third link position R3 to the fourth link position R4 along the second sliding direction G2 on the second link wall 3b, wherein the second sliding direction G2 is opposite to the first sliding direction G1; during the process of the second blade 5 rotating from the fourth blade position B4 to the third blade position B3 along the fourth rotation direction S4, the second blade connecting part 51 slides from the eleventh link position R11 to the twelfth link position R12 along the sixth sliding direction G6 on the sixth link wall 3h, wherein the sixth sliding direction G6 is opposite to the fifth sliding direction G5. The sixth sliding direction G6 is opposite to the second sliding direction G2.

[0054] exist Figure 13In this diagram, angles α and β are both 45°, the second blade position B2 and the fourth blade position B4 are at 45°, and the first blade position B1 and the third blade position B3 are at 0°. In embodiments not shown, angle α can be other values, and the first blade position B1, the second blade position B2, the third blade position B3, and the fourth blade position B4 can be other positions.

[0055] Combination Figure 10 , 11 As shown in 12 and 13, the first connecting rod wall 3a and the second connecting rod wall 3b are arranged parallel to each other and opposite to each other; the fifth connecting rod wall 3g and the sixth connecting rod wall 3h are arranged parallel to each other and opposite to each other; the first blade connecting part 21 is located between the first connecting rod wall 3a and the second connecting rod wall 3b; and the second blade connecting part 51 is located between the fifth connecting rod wall 3g and the sixth connecting rod wall 3h. More specifically, the first blade connecting part 21 is cylindrical in shape, and its diameter is equal to the distance between the parallel first connecting rod wall 3a and the second connecting rod wall 3b; the second blade connecting part 51 is cylindrical in shape, and its diameter is equal to the distance between the parallel fifth connecting rod wall 3g and the sixth connecting rod wall 3h. Figure 10 As shown, the first link wall 3a and the second link wall 3b can be connected by an arc-shaped surface 3e, and the fifth link wall 3g and the sixth link wall 3h can be connected by an arc-shaped surface 3i. In embodiments not shown, the first link wall 3a and the second link wall 3b may not be parallel, and the fifth link wall 3g and the sixth link wall 3h may not be parallel.

[0056] Continue to refer to Figure 10 , 11 12, 13, the sliding directions G1 and G2 of the first blade connecting part 21 on the connecting rod 3 are perpendicular to the translation directions T1 and T2 of the connecting rod 3 relative to the main frame 1; the sliding directions G5 and G6 of the second blade connecting part 51 on the connecting rod 3 are perpendicular to the translation directions T1 and T2 of the connecting rod 3 relative to the main frame 1.

[0057] Continue to refer to Figure 10 , 11 12, 13, the translation directions T1 and T2 of link 3 relative to the main frame 1 are parallel to the main frame 1. This design ensures that link 3 will not move in a direction perpendicular to the main frame 1 during movement.

[0058] The translational motion of link 3 relative to the main frame 1 can be achieved in several ways. For example... Figure 2A , 7As shown in figures 9, 10, 11, 12, and 13, the connecting rod 3 is slidably engaged with the main frame 1. More specifically, the connecting rod 3 has a sliding portion 31; the main frame 1 has a sliding groove 1b; the sliding portion 31 is slidably disposed in the sliding groove 1b. The extending direction of the sliding groove 1b is consistent with the translational directions T1 and T2 of the connecting rod 3 relative to the main frame 1. In an embodiment not shown in the figures, the connecting rod 3 can be directly connected to the drive assembly 4 without slidingly engaging with the main frame 1, and is driven by the drive assembly 4 to translate relative to the main frame 1.

[0059] There are several ways to achieve the movement of the drive assembly 4 driving the connecting rod 3. In an embodiment not shown in the accompanying drawings, the drive assembly 4 may include a gear and a rack. The rack is connected to the connecting rod 3, and the gear drives the connecting rod to move by driving the rack.

[0060] In another embodiment, such as Figure 1B , 3 As shown in Figures 4, 5, 6, and 8, the drive assembly 4 includes a base 40 and a rotating member 41. The base 40 has a motor that drives the rotating member 41 to rotate along the rotating member axis BB. The base 40 is mounted on the main frame 1. The connecting rod 3 has a third connecting rod wall 3c. The rotating member 41 has a rotating member axis BB and a rotating member connecting portion 411. The rotating member connecting portion 411 is offset from the rotating member axis BB. The rotating member 41 is rotatably mounted on the base 40 along the rotating member axis BB. The rotating member connecting portion 411 is used to push the third connecting rod wall 3c so that the connecting rod 3 moves relative to the main frame 1 in a first translational direction T1. Figure 10 As shown in Figure 11, during the process of connecting rod 3 moving relative to the main frame 1 from the first frame position F1 to the second frame position F2 along the first translation direction T1, the rotating part connecting part 411 slides on the third connecting rod wall 3c along the third sliding direction G3 from the fifth connecting rod position R5 to the sixth connecting rod position R6. This design has the advantage of simple structure.

[0061] like Figure 12 , 13 As shown, the link 3 has a fourth link wall 3d; the rotating member connecting part 411 is used to push the fourth link wall 3d so that the link 3 moves relative to the main frame 1 along the second translation direction T2, wherein the second translation direction T2 is opposite to the first translation direction T1; during the process of the link 3 moving from the second frame position F2 to the first frame position F1 along the second translation direction T2, the rotating member connecting part 411 slides on the fourth link wall 3d along the fourth sliding direction G4 from the seventh link position R7 to the eighth link position R8.

[0062] Continue to refer to Figure 10 , 1112, 13, the third link wall 3c and the fourth link wall 3d are arranged parallel and opposite to each other, and the rotating member connecting part 411 is located between the third link wall 3c and the fourth link wall 3d. The sliding directions G3 and G4 of the rotating member connecting part 411 on the link 3 are perpendicular to the translation directions T1 and T2 of the link 3 relative to the main frame 1. More specifically, the rotating member connecting part 411 is cylindrical in shape, and its diameter is equal to the distance between the parallel third link wall 3c and the fourth link wall 3d. The diameter of the rotating member connecting part 411 is equal to the diameter of the blade connecting part 21. In embodiments not shown, the third link wall 3c and the fourth link wall 3d may not be parallel. Figure 6 , 8 As shown in Figure 10, the third link wall 3c and the fourth link wall 3d can be connected by a flat surface 3f.

Figure 15 In this embodiment, the angle α is 90°, and the second blade position B2 is also called the 90° position. In this embodiment, the first blade position B1 is the 0° position.

[0068] When the first blade 2 rotates from the 90° position to the 45° position, the first blade connecting part 21 slides from the third link position R3 along the first sliding direction G1 to the first intermediate position R', the second blade connecting part 51 slides from the eleventh link position R11 along the fifth sliding direction G5 to the third intermediate position R, the rotating part connecting part 411 slides from the seventh link position R7 along the third sliding direction G3 to the second intermediate position R', and the connecting rod 3 moves from the second frame position F1 along the second translation direction T2 to the frame intermediate position F'.

[0073] like Figure 5 , 9 As shown, the axis BB of the rotating component is parallel to the axis AA of the blade rotation. The rotating component connecting part 411 and the blade connecting part 21 are respectively located on both sides of the connecting rod 3. This design makes the structure compact.

[0074] Specifically, the connecting rod 3 has side walls. The first connecting rod wall 3a and the second connecting rod wall 3b are located on one side of the side wall, such as the outer side, while the third connecting rod wall 3c and the fourth connecting rod wall 3d are located on the other side of the side wall, such as the inner side. The sliding part 31 is connected to the side wall and is located on the outer side of the side wall. The rotating member connecting part 411 and the blade connecting part 21 are respectively provided on both sides of the side wall of the connecting rod 3.

[0075] More specifically, such as Figure 8 As shown, the connecting rod 3 has a first sidewall 301, a second sidewall 302, and a bottom wall 300. The first sidewall 301 and the second sidewall 302 are each recessed from the outside to form a first connecting rod wall 3a, a second connecting rod wall 3b, a fifth connecting rod wall 3g, and a sixth connecting rod wall 3h; the first sidewall 301 and the second sidewall 302 are each recessed from the inside to form a third connecting rod wall 3c and a fourth connecting rod wall 3d. The two sides of the first sidewall 301 and the second sidewall 302 that are opposite each other are their respective inside sides.

[0076] like Figure 10 , 12 As shown, the first blade connecting portion 21 and the second blade connecting portion 51 define a straight line L, and the first blade rotation axis AA and the second blade rotation axis CC are located on both sides of this straight line L. This design makes it easy to realize that the first rotation direction S1 and the third rotation direction S3 are opposite.

[0077] More specifically, the straight line L can be a straight line passing through the center of the first blade connecting portion 21 and the second blade connecting portion 51. The straight line L is not a fixed straight line; it moves as the first blade connecting portion 21 and the second blade connecting portion 51 move. The straight line L also varies depending on the selected first blade connecting portion 21 and second blade connecting portion 51.

[0078] The first sidewall 301 and the second sidewall 302 are connected to the two opposite edges of the bottom wall 300 and extend toward the same side of the bottom wall 300.

[0079] like Figure 2AAs shown, the main frame 1 also has a cavity 1c; the connecting rod 3 is translatably disposed in the cavity 1c. Since the connecting rod 3 is configured to translate relative to the main frame 1, the depth of the cavity 1c can be controlled.

[0080] like Figure 2B As shown, the main frame 1 includes a frame body 10 and a cover 11; the frame body 10 has an air vent 1a and a cavity 1c; the cover 11 is connected to the frame body 10 to close the cavity 1c. A drive assembly 4 is disposed between the frame body 10 and the cover 11, wherein the drive assembly 4 is fixed to the inner wall of the cover 11. More specifically, a base 40 is fixed to the inner wall of the cover 11.

[0081] In an embodiment not shown, the shape of the connecting rod 3 can be configured as a curved shape according to the positions of the first blade 2 and the second blade 5, and correspondingly, the shape of the cavity 1c is also curved. The groove 1b can be located in the cavity 1c.

[0082] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present invention. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope defined by the claims of the present invention.
