DETAILED DESCRIPTION

[0029] Embodiments of the present invention are described in detail below, 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 be used to explain the present invention, and should not be construed as limiting the present invention.

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

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

[0032] Specifically, an air inlet is formed on the frame 1, and the adjustment component 2 is arranged at the air inlet for adjusting the air intake at the air inlet. The driving member 3 is arranged on the frame 1, and the driving member 3 is connected to the adjustment component 2, wherein the adjustment component 2 includes: an adjustment link 21 and an adjustment swing arm 22, and the adjustment swing arm 22 is connected between the adjustment link 21 and the driving member 3 to drive the adjustment link 21 to move in the Z direction. Therefore, the active air intake grille 100 has a simple structure, a clever design, is easy to assemble, and has a low production cost.

[0033] It can be understood that the active air intake grille 100 automatically adjusts the size of the air intake according to the vehicle driving state and the power system cooling requirements, thereby optimizing the aerodynamic performance and improving the energy consumption level of the vehicle. 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 swing arm 22 is connected between the adjustment link 21 and the driving member 3. When the driving member 3 is working, the adjustment swing arm 22 will drive the adjustment link 21 in the vertical direction (such as Figure 1 The position of the regulating component 2 is changed to control the opening of the air inlet.

[0034] When the vehicle needs better aerodynamic performance, such as when driving at high speed, the adjustment component 2 will be closed or partially closed to reduce the air entering the front cabin, thereby reducing air resistance; when the cooling effect needs to be increased, such as in traffic jams, the adjustment component 2 will open to allow more air to flow into the front cabin for heat dissipation. This can improve 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 to be connected with 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 requirements of different working conditions of the automobile to achieve the effect of optimizing performance. The multi-link structure plays a role of 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 an 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, and 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 move under the influence of the driving force, and 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, a transmission shaft 222 is formed on the adjustment swing arm 22, and the transmission shaft 222 is arranged at intervals with the matching groove 221. The frame 1 includes a support plate 11, one end of the transmission shaft 222 is connected to the driving member 3, and the other end of the transmission shaft 222 is rotatably arranged on the support plate 11. It can be understood that the driving member 3 directly drives the transmission shaft 222 to rotate. When the driving member 3 works, it drives the transmission shaft 222 to rotate, thereby causing the adjustment swing arm 22 to rotate around the center line of the transmission shaft 222, and through the linkage of the matching groove 221 and the matching rod 211, the rotation is transmitted to the adjustment link 21, so that the adjustment link 21 is displaced in the Z direction accordingly, thereby adjusting the opening of the air inlet. In this way, it is ensured that the adjustment swing arm 22 can rotate smoothly and reliably, and then the precise control of the intake volume is achieved through mechanical linkage, the structure of the active air intake grille 100 is simplified, and the response speed and reliability of the active air intake grille 100 are improved.

[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 via the spline.

[0040] In some embodiments of the present invention, the adjustment component 2 further includes: a blade 23, the blade 23 is multiple, for example, the blade 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 in the Y direction are provided with a first rotating shaft 231, and 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 arranging a plurality of blades 23, the airflow distribution of the air inlet can be made more uniform, thereby further improving the uniformity of the airflow 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 plurality of blades 23 to rotate, the plurality of blades 23 can be made to rotate 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, wherein the support plate 11 is disposed on a side of the air inlet close to the driving member 3, and the pressure plate 4 is disposed on a side of the air inlet away from the driving member 3, wherein the pressure plate 4 cooperates with the edge of the air inlet to define a first shaft hole, and a second shaft 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 shaft hole and the second shaft hole respectively. Thus, the blade 23 can be rotatably arranged at the air inlet, wherein, by providing the pressure plate 4, when the model of the first rotating shaft 231 of the blade 23 changes, the first shaft hole can be adapted to the first rotating shaft 231 of the blade 23 by adjusting the model of the pressure plate 4, and 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 a fastener.

[0042] In some embodiments of the present invention, Figure 4 As shown, the adjusting link 21 also includes a rod body 212, the rod body 212 extends along the Z direction, the matching rod 211 is arranged on the side of the rod body 212 facing the adjusting swing arm 22, the rod body 212 is formed with a plurality of third shaft holes 2121 arranged at intervals along the Z direction, and each blade 23 is formed with a second rotating shaft 232 at one end close to the support plate 11, and the second rotating shaft 232 corresponds to the third shaft hole 2121 one by one. In this way, the transmission connection between the adjusting swing arm 22 and the plurality of blades 23 can be realized, and in the process of product design, the size, relative position or relative angle and other parameters of the rod body 212, the first rotating shaft 231 and the second rotating shaft 232 can be adjusted to meet more product design needs.

[0043] In some embodiments of the present invention, Figure 4 As shown, a boss 213 extending in the radial direction of the matching rod 211 is formed at one end of the matching rod 211 away from the rod body 212 to limit the relative movement of the adjusting swing arm 22 and the adjusting connecting rod 21 in the Y direction, ensuring that the adjusting connecting rod 21 will not fall out of the slide slot during the movement, thereby ensuring that the movement relationship between the adjusting swing arm 22 and the adjusting connecting rod 21 is more stable and reliable. By limiting the relative movement of the adjusting swing arm 22 in the Y direction, the system can better control the position of the blade 23, thereby achieving the purpose of accurately adjusting the intake volume.

[0044] In some embodiments of the present invention, Figure 3 As shown, the matching groove 221 is formed in a long strip shape, and the matching rod 211 can slide along the length direction of the matching groove 221. It can be understood that the sliding of the matching rod 211 in the matching groove 221 can make the adjustment link 21 more flexible to move without being constrained in other directions. Through the sliding cooperation between the matching groove 221 and the matching rod 211, the adjustment link 21 can be precisely controlled in the Z direction, thereby ensuring that the angle adjustment of the blade 23 is more accurate.

[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 can be understood that the driving member 3 drives the adjusting swing arm 22 to rotate through the output shaft 31, and the output shaft 31 of the driving member 3 is directly connected to the transmission shaft 222 of the adjusting swing arm 22, so that the power transmission is more direct, and the energy loss of the intermediate link is reduced. 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] The vehicle according to the second embodiment of the present invention comprises: a front bumper and an active air intake grille 100 according to the first embodiment of the present invention, the active air intake grille 100 is arranged on the front bumper, the vehicle has an on-board sensor, the on-board sensor transmits the detected data to the control unit, the control unit determines whether it is necessary to adjust the opening degree of the active air intake grille 100 according to the data, and according to the instruction of the control unit, the driving motor drives the adjustment swing arm 22, the adjustment swing arm 22 drives the adjustment link 21, and the adjustment link 21 drives the blade 23 to rotate, thereby changing the opening degree of the active air intake grille 100. When a larger air intake volume is required, the blade 23 rotates to increase the area of ​​the air intake port, allowing more air to enter; when the air intake volume needs to be reduced, the blade 23 rotates to reduce the area of ​​the air intake port, thereby limiting the entry of air.

[0048] According to the vehicle of the embodiment of the present invention, by setting the active air intake grille 100 of the first embodiment, the control flexibility of the active air intake grille 100 is improved, the difficulty of adjusting the air intake volume is reduced, a higher degree of freedom in styling design is met, and the performance of the vehicle is improved.
