DETAILED DESCRIPTION

[0029] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0030] Reference below Figures 1-8 An active air intake grille 100 according to an embodiment of the first aspect of the present invention is described.

[0031] like Figure 1 As shown, the active air intake grille 100 according to the embodiment of the first aspect of the present utility model includes: a frame 1, an adjustment component 2 and a driving member 3.

[0032] Specifically, an air inlet is formed on the frame 1. An adjustment assembly 2 is disposed at the air inlet for adjusting the airflow rate at the air inlet. A driver 3 is disposed on the frame 1 and connected to the adjustment assembly 2. The adjustment assembly 2 includes an adjustment link 21 and an adjustment swing arm 22. The adjustment swing arm 22 is connected between the adjustment link 21 and the driver 3 to drive the adjustment link 21 in the Z direction. As a result, the active air intake grille 100 has a simple structure, a clever design, is easy to assemble, and has low production costs.

[0033] It is understood that the active air intake grille 100 automatically adjusts the size of the air intake according to the vehicle's driving state and the power system's cooling requirements, thereby optimizing aerodynamic performance and improving the vehicle's energy consumption. When the driving member 3 is in motion, the motion is transmitted to the adjustment component 2 (such as the blade 23 or the baffle). The adjustment arm 22 is connected between the adjustment link 21 and the driving member 3. When the driving member 3 is in operation, the adjustment arm 22 drives the adjustment link 21 in the vertical direction (such as the vertical direction). Figure 1 The Z direction is shown, thereby changing the position of the regulating component 2 and controlling the opening of the air inlet.

[0034] When the vehicle requires improved aerodynamic performance, such as when driving at high speeds, the regulating assembly 2 closes or partially closes, reducing air flow into the front cabin and thus reducing air resistance. When increased cooling is required, such as in traffic jams, the regulating assembly 2 opens, allowing more air to flow into the front cabin for heat dissipation. This improves the vehicle's fuel economy and the effectiveness of the thermal management system.

[0035] According to the active air intake grille 100 of the embodiment of the present invention, an adjusting link 21 and an adjusting swing arm 22 are provided, which are connected to the driving member 3 and the blade 23, thereby forming a linkage structure, which realizes the rotation of the blade 23. The opening state of the blade 23 can be adjusted according to the needs under different working conditions of the automobile to achieve the effect of optimizing performance. The multi-link structure plays a role in unloading force to prevent the motor from having broken teeth.

[0036] like Figure 1 As shown, ABC1D1, ABC2D2, and ABC3D3 are four-bar linkages consisting of each blade 23 and the adjusting swing arm 22.

[0037] In some embodiments of the present invention, a matching groove 221 is formed on the adjusting swing arm 22, and a matching rod 211 is formed on the adjusting link 21. The matching rod 211 extends into the matching groove 221, so that the driving member 3 can drive the adjusting link 21 to move together through the adjusting swing arm 22. When the driving member 3 is working, the adjusting swing arm 22 will be affected by the driving force and move. The matching groove 221 and the matching rod 211 cooperate with each other to guide the adjusting link 21 to move along a predetermined path, ensuring that the movement of the adjusting link 21 is controlled and accurate, thereby effectively controlling the opening degree of the air intake.

[0038] In some embodiments of the present invention, Figure 1-Figure 5 As shown, the adjustment arm 22 is formed with a transmission shaft 222, which is spaced apart from the mating slot 221. The frame 1 includes a support plate 11. One end of the transmission shaft 222 is connected to the driver 3, and the other end of the transmission shaft 222 is rotatably mounted on the support plate 11. It is understood that the driver 3 directly drives the transmission shaft 222 to rotate. When the driver 3 is in operation, it drives the transmission shaft 222 to rotate, thereby causing the adjustment arm 22 to rotate about the centerline of the transmission shaft 222. This rotation is then transmitted to the adjustment link 21 through the linkage of the mating slot 221 and the mating rod 211, causing the adjustment link 21 to move accordingly in the Z direction, thereby adjusting the opening of the air inlet. This ensures that the adjustment arm 22 can rotate smoothly and reliably, thereby achieving precise control of the air intake volume through mechanical linkage. This simplifies the structure of the active air intake grille 100 and improves its response speed and reliability.

[0039] like Figure 3 As shown, one end of the transmission shaft 222 is formed as a spline, and the transmission shaft 222 is connected to the driving member 3 through the spline.

[0040] In some embodiments of the present invention, the adjustment component 2 further includes: blades 23, the blades 23 are multiple, for example, the blades 23 can be two, three or four, and the multiple blades 23 are in the Z direction (such as Figure 5 The two ends of each blade 23 are rotatably connected to the inner wall of the air inlet through the first rotating shaft 231. By providing multiple blades 23, the air flow distribution of the air inlet can be made more uniform, thereby further improving the uniformity of the air flow blown to the heat dissipation system, and further improving the uniformity of the heat dissipation of the heat dissipation system. By adjusting the connecting rod 21 to drive the multiple blades 23 to rotate, the multiple blades 23 can be rotated synchronously, thereby further improving the uniformity of the air intake.

[0041] In some embodiments of the present invention, the active air intake grille 100 further includes: a support plate 11 and a pressure plate 4. The support plate 11 is disposed on the side of the air inlet close to the driver 3, and the pressure plate 4 is disposed on the side of the air inlet away from the driver 3. The pressure plate 4 cooperates with the edge of the air inlet to define a first axial hole. A second axial hole is formed on the support plate 11, and the first rotating shaft 231 at both ends of each blade 23 cooperates with the first axial hole and the second axial hole, respectively. Thus, the blade 23 can be rotatably disposed at the air inlet. By providing the pressure plate 4, when the model of the first rotating shaft 231 of the blade 23 changes, the model of the pressure plate 4 can be adjusted to adapt the first axial hole to the first rotating shaft 231 of the blade 23. The structure of the pressure plate 4 is relatively simple, which can reduce the difficulty and cost of product development. Preferably, the pressure plate 4 is connected to the edge of the air inlet by fasteners.

[0042] In some embodiments of the present invention, Figure 4 As shown, the adjustment link 21 also includes a rod body 212, which extends along the Z direction. The matching rod 211 is provided on the side of the rod body 212 facing the adjustment swing arm 22. The rod body 212 is formed with a plurality of third axial holes 2121 spaced apart along the Z direction. Each blade 23 is formed with a second rotating shaft 232 at one end near the support plate 11, and the second rotating shaft 232 corresponds one-to-one with the third axial hole 2121. In this way, a transmission connection between the adjustment swing arm 22 and the plurality of blades 23 can be achieved through the adjustment link 21. During the product design process, the size, relative position, or relative angle of the rod body 212, the first rotating shaft 231, and the second rotating shaft 232 can be adjusted to meet more product design requirements.

[0043] In some embodiments of the present invention, Figure 4 As shown, a boss 213 extending radially along the mating rod 211 is formed at one end of the mating rod 211, distal from the rod body 212. This limits the relative movement of the adjustment arm 22 and the adjustment link 21 in the Y direction, ensuring that the adjustment link 21 does not fall out of the chute during movement. This further ensures a more stable and reliable kinematic relationship between the adjustment arm 22 and the adjustment link 21. By limiting the relative movement of the adjustment arm 22 in the Y direction, the system can better control the position of the blade 23, thereby achieving the purpose of precisely adjusting the intake air volume.

[0044] In some embodiments of the present invention, Figure 3As shown, the mating slot 221 is formed in an elongated strip shape, and the mating rod 211 is slidable along the length of the mating slot 221. It is understood that the sliding of the mating rod 211 in the mating slot 221 enables the adjustment link 21 to move more flexibly without being constrained in other directions. Through the sliding engagement between the mating slot 221 and the mating rod 211, precise control of the adjustment link 21 in the Z direction can be achieved, thereby ensuring more accurate angle adjustment of the blade 23.

[0045] In some embodiments of the present invention, the driving member 3 has an output shaft 31, and the output shaft 31 is connected to the transmission shaft 222 of the adjusting swing arm 22. It is understood that the driving member 3 drives the adjusting swing arm 22 to rotate via the output shaft 31. The output shaft 31 of the driving member 3 is directly connected to the transmission shaft 222 of the adjusting swing arm 22, making power transmission more direct and reducing energy loss in the intermediate links. The rotation of the output shaft 31 can directly control the rotation angle of the adjusting swing arm 22, thereby accurately adjusting the angle of the blade 23.

[0046] Preferably, the driving member 3 is a driving motor.

[0047] A vehicle according to an embodiment of the second aspect of the present invention includes: a front bumper and an active air intake grille 100 according to the embodiment of the first aspect of the present invention. The active air intake grille 100 is disposed on the front bumper. The vehicle has an onboard sensor that transmits detected data to a control unit. The control unit determines, based on the data, whether the opening degree of the active air intake grille 100 needs to be adjusted. Based on instructions from the control unit, a drive motor drives an adjustment arm 22. The adjustment arm 22 drives an adjustment link 21. The adjustment link 21 drives a vane 23 to rotate, thereby changing the opening degree of the active air intake grille 100. When a greater amount of air intake is required, the vane 23 rotates to increase the area of ​​the air intake, allowing more air to enter. When a smaller amount of air intake is required, the vane 23 rotates to decrease the area of ​​the air intake, restricting air from entering.

[0048] According to the vehicle of the embodiment of the present utility model, the active air intake grille 100 of the above-mentioned first embodiment is provided, thereby improving the control flexibility of the active air intake grille 100, reducing the difficulty of adjusting the air intake volume, meeting a higher degree of freedom in styling design, and improving the performance of the vehicle.
