[0049] The present utility model will be described in detail below by way of describing exemplary embodiments.

[0050] Figure 1 and Figure 2 FIG. shows a part of the active intake assembly according to an embodiment of the present utility model. According to the present utility model, the active intake assembly includes a frame provided with an opening for intake. The active intake assembly can be installed on a vehicle, such as at the front face of the vehicle. For example, the frame of the active intake assembly is installed on the main frame of the vehicle or forms a part of the main frame of the vehicle. Figure 1 and Figure 2 The components of the active intake assembly shown in FIG. are configured to be integrally installed on the frame of the active intake assembly. The first blade 100 and the second blade 200 of the active intake assembly are located in the opening of the frame to close or open the opening.

[0051] Specifically, as shown in Figure 1 and Figure 2 FIG., the active intake assembly includes a first blade 100 and a second blade 200. The first blade 100 and the second blade 200 are rotatably fixed to the frame of the active intake assembly, and the first blade 100 and the second blade 200 can rotate around the first rotation axis 101 and the second rotation axis 201 respectively. The first blade 100 includes a first main body 110 and a first rotating arm 120. One end of the first rotating arm 120 is fixedly installed on the first main body 110, and the other end of the first rotating arm 120 is rotatably installed on the frame to define the first rotation axis 101. The second blade 200 includes a second main body 210 and a second rotating arm 220. One end of the second rotating arm 220 is fixedly installed on the second main body 210, and the other end of the second rotating arm 220 is rotatably installed on the frame to define the second rotation axis 201.

[0052] As Figure 1 and Figure 2 shown, both the first rotating arm 120 and the second rotating arm 220 are formed as sheet bodies, and respectively have connection portions with longer cross-sections with the first main body 110 and the second main body 210, such that the first rotating arm 120 and the second rotating arm 220 have greater strength themselves and respectively have greater connection strength with the first main body 110 and the second main body 210. On the other hand, pin members are fixedly provided on the first rotating arm 120 and the second rotating arm 220, and are rotatably mounted to the frame through the pin members. As Figure 1 and Figure 2 specifically shown, the pin member 121 of the first rotating arm 120 and the pin member 221 of the second rotating arm 220 are both pins with a circular outer contour conforming to a spline form. In other words, the pin member 121 and the pin member 221 can be regarded as cylinders formed by removing at least one volume from the side surface of a cylinder. Thus, the pin member 121 and the pin member 221 can be respectively received in circular holes on the frame and rotate relative to the corresponding circular holes, such that the first blade 100 and the second blade 200 respectively rotate around the first rotation axis 101 and the second rotation axis 201.

[0053] Referring to Figure 3 and Figure 4 , the first blade 100 may have a third rotating arm 130, the second blade 200 may have a fourth rotating arm 230, the third rotating arm 130 and the fourth rotating arm 230 may respectively be fixedly provided with pin members (such as cylindrical pins), and are rotatably mounted to the frame via their respective pin members. In other words, the pin member of the third rotating arm 130 is located on the first rotation axis 101, and the pin member of the fourth rotating arm 230 is located on the second rotation axis 201, thereby forming a more stable support for the rotation of the first blade 100 and the second blade 200. As Figure 4 shown, the corresponding rotating arm may be integrally formed with at least a part of the main body of the first blade 100 or the second blade 200, such that the first blade 100 and the second blade 200 have further improved overall strength.

[0054] In Figure 1 , both the first blade 100 and the second blade 200 are in the closed position, that is, the first blade 100 and the second blade 200 close the opening of the frame. In Figure 2 , both the first blade 100 and the second blade 200 are in the open position, that is, the first blade 100 and the second blade 200 open the opening of the frame. The first blade 100 and the second blade 200 rotate from the closed position to the open position in opposite rotation directions, thereby forming an unobstructed space for air flow between the first blade 100 and the second blade 200. Thus, the maximum air intake volume of the active air intake assembly can be increased, and the air intake control ability of the active air intake assembly can be improved.

[0055] As Figure 1 and Figure 2 shown, the active intake assembly further includes a driving member 300. The driving member 300 is configured to rotate about a driving member rotation axis 301 under the drive of a driving force. Among them, the driving force is provided by a motor (not shown) for example, and the driving member rotation axis 301 is arranged between a first rotation axis 101 and a second rotation axis 201, and may be parallel to the first rotation axis 101 and the second rotation axis 201. The driving member 300 includes a torque receiving portion 310 and a driving force output rod 320. Among them, the torque receiving portion 310 is configured to receive the driving force. For example, the torque receiving portion 310 can be splined with the output shaft of the motor to be driven to rotate by the motor fixed relative to the frame, thereby defining the fixed driving member rotation axis 301 of the driving member 300. The driving force output rod 320 of the driving member 300 is rod-shaped, and its first end 321 is rotatably fixedly connected to the torque receiving portion 310, so that the driving force output rod 320 rotates synchronously with the torque receiving portion 310. The driving force output rod 320 extends transversely to the driving member rotation axis 301 to output the driving force.

[0056] Further, as Figure 1 and Figure 2 specifically shown, the torque receiving portion 310 extends along the driving member rotation axis 301 and has a columnar main body, and the driving force output rod 320 is fixed to the torque receiving portion 310 perpendicular to the driving member rotation axis 301. Thus, the driving member 300 drives the first blade 100 and the second blade 200 with less material.

[0057] Still referring to Figure 1 and Figure 2 , the active intake assembly further includes a first transmission rod 500 and a second transmission rod 600. One end of each of the first transmission rod 500 and the second transmission rod 600 is respectively rotatably connected to the second end 322 of the driving force output rod 320 of the driving member 300. On the other hand, the first blade 100 and the second blade 200 are respectively provided with a first connection point 125 and a second connection point 225. The other end of the first transmission rod 500 is rotatably connected to the first connection point 125, and the other end of the second transmission rod 600 is rotatably connected to the second connection point 225. Thus, the rotation of the driving member 300 drives the movement of the first transmission rod 500 and the second transmission rod 600 via the driving force output rod 320, and the first transmission rod 500 and the second transmission rod 600 then respectively drive the first blade 100 and the second blade 200 to rotate.

[0058] Specifically, the first blade 100 is provided with a first rod member 150, and the second blade 200 is provided with a second rod member 250. Among them, the first rod member 150 is arranged between the first rotation axis 101 and the first connection point 125. One end of the first rod member 150 located at the first rotation axis 101 is in spline fit with a spline-shaped pin member 121, so that the first rod member 150 can rotate synchronously with the first blade 100. One end of the first rod member 150 located at the first connection point 125 is rotatably connected to the first transmission rod 500, so that the first transmission rod 500 can apply a force to the first rod member 150, thereby driving the first blade 100 to rotate. The second rod member 250 is arranged between the second rotation axis 201 and the second connection point 225. One end of the second rod member 250 located at the second rotation axis 201 is in spline fit with a spline-shaped pin member 221, so that the second rod member 250 can rotate synchronously with the second blade 200. One end of the second rod member 250 located at the second connection point 225 is rotatably connected to the second transmission rod 600, so that the second transmission rod can apply a force to the second rod member 250, thereby driving the second blade 200 to rotate.

[0059] According to an embodiment of the present invention, the first transmission rod 500 and the second transmission rod 600 can be connected to the same connection point 325 on the driving force output rod 320, so that the driving force output rod 320 has greater strength and reduced manufacturing cost. Additionally, specifically referring to Figure 3 , the first transmission rod 500 and the second transmission rod 600 can be arranged on both sides of the driving force output rod 320 along the driving member rotation axis 301 to reduce the overall volume of the driving member (the driving member includes, for example, the driving member 300, the first transmission rod 500, and the second transmission rod 600) for driving the blade to rotate.

[0060] Figure 5A and Figure 5B respectively show two working states of the first blade 100 and the second blade 200 in the active intake assembly according to the present invention. In Figure 5A , the first blade 100 and the second blade 200 are in the closed position, and in Figure 5B , the first blade 100 and the second blade 200 are in the open position.

[0061] Referring to Figure 5A and Figure 5B for the positions of the first blade 100 and the second blade 200, in order to move the first blade 100 and the second blade 200 from the closed position to the open position, a driving force is provided to the torque receiving portion 310 of the driving member 300, so that the torque receiving portion 310 is in Figure 5A and Figure 5BRotating clockwise from the perspective of [reference], the driving force output rod 320 rotates clockwise, and the second end 322 of the driving force output rod moves downward. Thus, the first transmission rod 500 is pushed downward, and a substantially downward force is applied to the first blade 100 through the first connection point 125, and then the first blade 100 rotates counterclockwise to its open position. At the same time, the second transmission rod 600 is pulled downward, and a substantially downward force is applied to the second blade 200 through the second connection point 225, and then the second blade 200 rotates clockwise to its open position.

[0062] On the other hand, in order to move the first blade 100 and the second blade 200 from the open position to the closed position, a driving force is provided to the torque receiving portion 310 of the driving member 300, so that the torque receiving portion 310 rotates counterclockwise in the Figure 5A and Figure 5B perspective, so that the driving force output rod 320 rotates counterclockwise, and the second end 322 of the driving force output rod moves upward. Thus, the first transmission rod 500 is pulled upward, and a substantially upward force is applied to the first blade 100 through the first connection point 125, and then the first blade 100 rotates clockwise to its closed position. At the same time, the second transmission rod 600 is pushed upward, and a substantially upward force is applied to the second blade 200 through the second connection point 225, and then the second blade 200 rotates counterclockwise to its closed position.

[0063] In addition, it can be seen from Figure 5A and Figure 5B that the rotation angle of the first blade 100 from the closed position to the open position is different from the rotation angle of the second blade 200 from the closed position to the open position. For example, the main body of the first blade 100 is arranged substantially vertically in the closed position, and the main body of the second blade 200 is arranged obliquely to the vertical direction in the closed position to meet the vehicle's appearance design requirements. On the other hand, the main bodies of the first blade 100 and the second blade 200 in the open position are both arranged substantially horizontally. Thus, when designing the appearance of the active intake assembly according to requirements, the intake control ability of the active intake assembly can also be adjusted, for example, by adjusting the positions of the rotatable connection points between the components.

[0064] The exemplary embodiments of the active intake assembly and the vehicle proposed by the present utility model have been described in detail above with reference to the preferred embodiments. However, those skilled in the art can understand that, without departing from the concept of the present utility model, various modifications and variations can be made to the above specific embodiments, and various combinations of the technical features and structures proposed by the present utility model can be made without exceeding the protection scope of the present utility model.
