[0048] Please refer to Figures 2-9 This application provides an air intake grille. Please refer to... Figure 2 The air intake grille includes a grille frame 100, blades 200, and a drive assembly 300. The grille frame 100 is mounted on the front end of the vehicle and provides a mounting reference for the blades 200. Specifically, the grille frame 100 has an air inlet 100a through which airflow passes, and the blades 200 are located at the air inlet 100a and can adjust the airflow through the air inlet 100a by their own movement. Exemplarily, the grille frame 100 is made of metal or plastic.

[0049] Please refer to Figures 3-5 The blade 200 has an open position and a closed position. It can be understood that when the blade 200 is in the closed position, the intake flow rate is essentially zero. When the blade 200 is in the open position, the intake flow rate is at its maximum. It should be noted that the blade 200 can move and remain in either the closed or open position, and can also move and remain in any position between the closed and open positions, for example... Figure 4 The position shown allows for adaptive adjustment of the intake airflow.

[0050] The drive assembly 300 is used to drive the blade 200 to move between an open position and a closed position, thereby adjusting the intake airflow. The movement of the blade 200 can be either oscillating or sliding.

[0051] When the blade 200 is in the closed position, it can close the air inlet 100a. In this closed position, along the air intake direction, the projection of the blade 200 onto a reference plane perpendicular to the air intake direction can cover the projection of the air inlet 100a onto the reference plane perpendicular to the air intake direction. Wherein, the air intake direction is... Figures 3-5 The direction shown.

[0052] When the blades 200 are in the open position, along the air intake direction, the projection of the blades 200 onto a reference plane perpendicular to the air intake direction does not overlap with the projection of the air intake 100a onto the same reference plane. Thus, the blades 200 do not obstruct the air intake 100a, thereby improving the area utilization of the air intake 100a and increasing the air intake area and air volume. Consequently, with a fixed air intake volume, the overall volume of the air intake grille can be reduced, improving the overall appearance of the vehicle.

[0053] Please refer to Figure 6 In some embodiments, the drive assembly 300 includes a drive member 310 and a linkage assembly 320. The blade 200 and the linkage assembly 320 are rotatably connected. The drive member 310 drives the blade 200 to move between an open position and a closed position, and the linkage assembly 320 oscillates relative to the blade 200 as the blade 200 moves. Compared to sliding, oscillation provides a more natural and fluid visual effect. Furthermore, compared to the drive member 310 directly driving the blade 200, the method of moving the blade 200 by oscillating the linkage assembly 320 allows for more flexible positioning of the drive member, as it is not constrained by the blade 200.

[0054] It should be noted that the drive component 310 can drive the blade 200 through the linkage assembly 320, or it can be directly connected to and drive the blade 200, for example... Figure 8 and Figure 9 As shown, the drive component 310 connects to the blade 200 and, by applying a driving force to the blade 200, causes the connecting rod assembly 320 connecting the blade 200 to swing. The specific type of the drive component 310 is not limited; it can be a motor or a drive telescopic rod 310-1 such as a gas spring.

[0055] Among them, the drive component 310 is connected to the AGS (Active Grille System) signal, and the drive control of the drive component 310 is realized through the AGS.

[0056] Please refer to Figure 6 In some embodiments, the blade 200 has a rotating portion 210, which is rotatably connected to the grid frame 100. The blade 200 oscillates about the central axis of the rotating portion 210. The specific number of rotating portions 210 is not limited; there may be one or more. The structure of the rotating portion 210 is not limited. For example, the rotating portion 210 may be a hinge hole formed on the blade 200, which is rotatably connected by engaging with a hinge shaft connecting the grid frame 100. Alternatively, the rotating portion 210 may be a hinge shaft connected to the blade 200, which is rotatably connected by engaging with a hinge hole in the grid frame 100.

[0057] The drive component 310 drives the blade 200 to swing via the linkage assembly 320. It should be noted that the drive component 310 can be fixed to the grille frame 100 or to other components that are fixed relative to the grille frame 100.

[0058] Please refer to 3- Figure 6 The linkage assembly 320 includes a first link 321 and a second link 322 rotatably connected. The first link 321 and the second link 322 can swing relative to each other to adjust the included angle. The drive member 310 drives the second link 322 to swing, and the second link 322 transmits force to the first link 321, causing the included angle between them to change. The first link 321 and the second link 322 can be fixed rods, elastic telescopic rods, or one fixed rod and the other elastic telescopic rod. The elastic telescopic rod can absorb vibration and impact through its own elastic expansion and contraction, thereby reducing the damage to the blade 200 caused by external impacts from the first link 321. In some specific embodiments, the end of the second link 322 connected to the drive member 310 has a through groove, which can be sleeved on one end of the output shaft 330. The two are connected by a transmission key such as a spline, so that when the output shaft 330 rotates, the second link 322 is driven to swing. One of the first link 321 and the second link 322 has a hinge shaft and the other has a hinge hole. The two work together to realize the rotational connection between the first link 321 and the second link 322.

[0059] The end of the first link 321 away from the second link 322 is rotatably connected to the blade 200. The driving member 310 is connected to the second link 322 and drives the second link 322 to swing, so that the first link 321 drives the blade 200 to swing around the central axis of the rotating part 210, thereby causing the blade 200 to swing to the open or closed position. In some specific embodiments, the first link 321 is hinged to the leeward side of the blade 200, and the angle between the first link 321 and the blade 200 changes during the swing of the second link 322.

[0060] In the above embodiment, the force of the driving component 310 is transmitted to the blade 200 through the second link 322 and the first link 321 in sequence, thereby enabling the blade 200 to swing to the open or closed position. At the same time, the second link 322 and the first link 321 can support the blade 200, thereby reducing the deformation of the blade 200 during vehicle movement and improving the accuracy of intake flow regulation.

[0061] To reduce the impact of wind on the blade 200 during operation when the blade 200 is in the closed position, in some embodiments, the blade 200 has a main body 250 and a connecting part 240. The main body 250 is the portion of the blade 200 that blocks the air inlet 100a. The connecting part 240 is disposed on the main body 250 and is rotatably connected to the first connecting rod 321. Along the width direction of the blade 200, the connecting part 240 and the rotating part 210 are respectively disposed on opposite sides of the main body 250. Thus, the position where the first connecting rod 321 is connected to the blade 200 is relatively far from the rotating part 210, thereby increasing the lever arm length of the drive member 310 driving the blade 200, and consequently reducing the driving force of the drive member 310 driving the blade 200.

[0062] Furthermore, in some embodiments, reference is made to Figure 6 The connecting portion 240 is formed on the leeward side of the blade 200. The connecting portion 240 extends and protrudes along the width direction of the blade 200, thereby dispersing the force on the blade 200 and improving the connection strength.

[0063] In some embodiments, when the blades 200 are in the open position, the projection of the drive assembly 300 onto a reference plane perpendicular to the air intake direction does not overlap with the projection of the air inlet 100a onto the same reference plane. In other words, the drive assembly 300 does not obstruct airflow, thereby further ensuring the air intake area.

[0064] The drive component 310 can be located above or below the air inlet 100a of the grille frame 100, or to the left or right of the air inlet 100a of the grille frame 100, depending on the volume of the drive component 300.

[0065] The blade 200 can be a single unit, which makes the structure relatively simple, reliable, and more efficient in assembly.

[0066] Please refer to Figure 7In other embodiments, the blade 200 is a split structure, including a first segment 220 and a second segment 230. The first segment 220 has a first rotating part 221 and is rotatably connected to one side of the grille frame 100 through the first rotating part 221. The second segment 230 has a second rotating part 231 and is rotatably connected to the opposite side of the grille frame 100 through the second rotating part 231. It is understood that both the first segment 220 and the second segment 230 can swing to an open position or a closed position. When the blade 200 is in the open position, that is, when both the first segment 220 and the second segment 230 are in the open position, the projections of the first segment 220 and the second segment 230 on the reference plane perpendicular to the air intake direction do not overlap with the projection of the air inlet 100a on the reference plane perpendicular to the air intake direction. When the blade 200 is in the closed position, that is, when the first segment 220 and the second segment 230 are in the closed position, the first segment 220 and the second segment 230 cooperate to seal the air inlet 100a.

[0067] During the opening process, both the first segment 220 and the second segment 230 swing backward. In some specific embodiments, the first segment 220 and the second segment 230 are hinged to the two long sides of the grille frame 100, with the first segment 220 hinged to the upper long side and the second segment 230 hinged to the lower long side. After swinging backward to the open position, the geometric center of the first segment 220 is tilted backward and upward, and the geometric center of the second segment 230 is tilted backward and downward. During the closing process, the geometric center of the first segment 220 is tilted forward and downward, and the geometric center of the second segment 230 is tilted forward and upward, until both are on the same plane.

[0068] In the above embodiments, compared with the entire blade 200, the use of the first segment 220 and the second segment 230 can reduce the space requirement behind it during the opening process, thereby facilitating its arrangement.

[0069] Furthermore, in order to drive the first segment 220 and the second segment 230, in some embodiments, the number of driving components 300 is two sets, one set of driving components 300 is configured to drive the first segment 220 to swing around the central axis of the first rotating part 221, and the other set of driving components 300 is configured to drive the second segment 230 to swing around the central axis of the second rotating part 231.

[0070] In some embodiments, multiple sets of linkage assemblies 320 are arranged in parallel along the length of the blade 200. These multiple sets of linkage assemblies 320 are connected to the blade 200 and driven by a single drive element 310, which improves stability and reduces the likelihood of significant swaying of the blade 200 under wind conditions.

[0071] Among them, reference Figure 6The drive unit 310 includes an output shaft 330. The second links 322 of each set of linkage assemblies 320 are driveably connected to the output shaft 330. The output shaft 330 is configured to drive the second links 322 to swing through its own rotation. In some specific embodiments, the drive unit 310 includes a motor and an output shaft 330. The motor has a hollow rotating part 341, and the output shaft 330 extends into the rotating part 341. A transmission key, such as a spline, is provided between the two. The grid frame 100 is provided with a bracket 110, and the output shaft 330 is rotatably mounted on the bracket 110. The output shaft 330 includes a first branch shaft and a second branch shaft. The first branch shaft and the second branch shaft are coaxially arranged and both extend into the rotating part 341 and are driveably connected to the rotating part 341.

[0072] Furthermore, if there are two sets of connecting rod assemblies 320, and the two sets of connecting rod assemblies 320 are supported on the back of the blade 200, the two connecting rod assemblies 320 and the end face of the blade 200 in the length direction are spaced apart, thereby improving the force on the blade 200 in the length direction, reducing the possibility of the blade 200 being significantly deformed by wind force, and meeting the strength requirements required by the design with a thinner thickness, which is beneficial to reducing manufacturing costs.

[0073] In some embodiments, the second link 322 and the first link 321 are located on a first plane, which is perpendicular to the blade 200. This allows the force to be transmitted directly along a direction perpendicular to the blade 200, minimizing losses caused by force directional deviation and improving energy transfer efficiency. Furthermore, the perpendicular arrangement to the blade 200 allows for more precise control of the blade 200's swing angle.

[0074] In some embodiments, please refer to Figures 3-5 A third rotating part 120 is provided on the grille frame 100. The third rotating part 120 is used to cooperate with the rotating part 210. The central axis of the third rotating part 120 extends along the length direction of the blade 200 and along the width direction of the air inlet 100a. The third rotating part 120 is located on the outside of the air inlet 100a. In this way, the blade 200 is located on the outside of the air inlet 100a, and the third rotating part 120 does not obstruct the airflow, thereby further ensuring the air intake area.

[0075] In some embodiments, please refer to Figures 3-5 A bracket 110 is provided on the grille frame 100. The end of the second link 322 away from the first link 321 is rotatably connected to the bracket 110. Along the air intake direction, the projection of the bracket 110 on the reference plane perpendicular to the air intake direction does not overlap with the projection of the air inlet 100a on the reference plane. In other words, the bracket 110 will not obstruct the airflow.

[0076] Please refer to Figures 8-9In some embodiments, the linkage assembly 320 includes a first link 321 and a second link 322, which respectively constitute two swingable rockers in a four-bar linkage. One end of the first link 321 and the second link 322 is movably hinged to the vehicle body and is at different heights. The other ends of the first link 321 and the second link 322 are sequentially rotatably connected to the blade 200 along the width direction of the blade 200.

[0077] The drive unit 310 is connected to the first link 321 and is configured to drive the first link 321 to swing, thereby moving the blade 200. This embodiment provides another different movement mode of the blade 200, and its blade 200 has better movement stability.

[0078] In other embodiments, the drive member 310 is drively connected to the second link 322 and is configured to drive the second link 322 to swing, thereby moving the blade 200.

[0079] In other embodiments, the drive member 310 is drively connected to the blade 200 and configured to drive the blade 200 to move. Specifically, the first connecting rod 321 and the second connecting rod 322 are rotatably connected to one side of the blade 200 in the width direction, and the drive member 310 is selected as a drive telescopic rod 310-1, which is rotatably connected to the other side of the blade 200 in the width direction. In some embodiments, when the blade 200 is in the closed position, the extension direction of the drive telescopic rod 310-1 is in the air intake direction, thereby providing more stable support.

[0080] This application also provides a vehicle, which can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large semi-trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0081] The vehicle includes at least one set of air intake grilles. When there are multiple sets of air intake grilles, the multiple sets of air intake grilles are arranged sequentially along the width direction of the vehicle.

[0082] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
