During the opening process of the first air deflector 30, the tangential lines of the intersection of the first driving groove 2011 and the first limiting groove 9011 are perpendicular. In other words, in the opening process of the first air deflector 30, the tangent line at the intersection with the first limit groove 9011 on the first drive groove 2011 and the tangent line at the intersection with the first drive groove 2011 on the first limit groove 9011 are perpendicular, so as to improve the smoothness of the first drive groove 2011 in driving the first drive shaft 701 to move, and avoid the occurrence of jamming in the moving process of the first drive shaft 701.

When the first air deflector 30 is in a closed state, the first driving groove 2011 intersects with the first limiting groove 9011, so that the first driving groove 2011 can drive the first driving shaft 701 to move, and opening of the first air deflector 30 is achieved.

In the closed state, the tangent lines of the first driving groove 2011 and the first limiting groove 9011 are perpendicular to each other.

The second air deflector 40 is in a closed state or in an open process, and the second driving groove 2021 intersects the second limit groove 9021.

The second air deflector 40 is in the opening process, and the second driving groove 2021 intersects with the second limiting groove 9021, so that the smoothness of the movement of the second driving shaft 801 driven by the second driving groove 2021 can be improved, and the reliability and stability of the movement of the second connecting rod 80 can be ensured.

During the opening process of the second air deflector 40, the tangential lines of the intersection of the second driving groove 2021 and the second limiting groove 9021 are perpendicular. In other words, in the process of opening the second air deflector 40, the tangent line at the intersection of the second driving groove 2021 and the second limiting groove 9021 is perpendicular to the tangent line at the intersection of the second limiting groove 9021 and the second driving groove 2021, so as to improve the smoothness of the movement of the second driving groove 2021 for driving the second driving shaft 801, and avoid the occurrence of jamming during the movement of the second driving shaft 801.

When the second air deflector 40 is in a closed state, the second driving groove 2021 intersects with the second limiting groove 9021, so that the second driving groove 2021 can drive the second driving shaft 801 to move, and opening of the second air deflector 40 is achieved.

In the closed state of the second air deflector 40, the tangential lines of the intersection of the second driving groove 2021 and the second limiting groove 9021 are perpendicular. In other words, during the opening process of the second air deflector 40, the tangent line of the second driving groove 2021 intersecting the second limiting groove 9021 is perpendicular to the tangent line of the second limiting groove 9021 intersecting the second driving groove 2021.

Optionally, the length of the first driving groove 2011 is less than or equal to the length of the first limiting groove 9011.

When the first driving groove 2011 drives the first driving shaft 701 to move, the first limiting shaft 702 is located in the first limiting groove 9011 and moves relative to the first limiting groove 9011. The length of the first driving groove 2011 is smaller than or equal to the length of the first limiting groove 9011, so that when the first driving groove 2011 can still continuously drive the first driving shaft 701 to move, the first limiting shaft 702 moves to the end point of the first limiting groove 9011, and therefore the first limiting shaft 702 cannot continuously move, and further the first connecting rod 70 cannot continuously move.

When the length of the first driving groove 2011 is equal to the length of the first limiting groove 9011, during the opening process of the first air deflector 30, when the first driving groove 2011 drives the first driving shaft 701 to move to the limit position (when the first driving shaft 701 moves to the end point of the first driving groove 2011), the first limiting shaft 702 just moves to the end point of the first limiting groove 9011, and at the moment, the first connecting rod 70 stops moving continuously, and the first air deflector 30 is opened to the maximum angle. The first limiting shaft 702 is located at an end point of the first limiting groove 9011, so that the first limiting groove 9011 can play a limiting role on the first limiting shaft 702, the first limiting shaft 702 is prevented from continuously moving towards the opening direction of the first air deflector 30, the position stability of the first limiting shaft 702 can be enhanced, and the stability of the position of the first connecting rod 70 when the first air deflector 30 is located at the maximum opening angle can be enhanced.

The length of the second driving groove 2021 is less than or equal to the length of the second limiting groove 9021.

When the second driving groove 2021 drives the second driving shaft 801 to move, the second limiting shaft 802 is located in the second limiting groove 9021 and moves relative to the second limiting groove 9021. The length of the second driving groove 2021 is less than or equal to the length of the second limiting groove 9021, so that when the second driving groove 2021 can still continuously drive the second driving shaft 801 to move, the second limiting shaft 802 moves to the end point of the second limiting groove 9021, and therefore the second limiting shaft 802 cannot continuously move, and further the second connecting rod 80 cannot continuously move.

When the length of the second driving groove 2021 is equal to the length of the second limiting groove 9021, during the opening process of the second air deflector 40, when the second driving groove 2021 drives the second driving shaft 801 to move to the limit position (when the second driving shaft 801 moves to the end point of the second driving groove 2021), the second limiting shaft 802 just moves to the end point of the second limiting groove 9021, and at this time, the second connecting rod 80 stops moving continuously, and the second air deflector 40 is opened to the maximum angle. The second limiting shaft 802 is located at an end point of the second limiting groove 9021, so that the second limiting groove 9021 can play a limiting role on the second limiting shaft 802, and the second limiting shaft 802 is prevented from continuously moving towards the opening direction of the second air deflector 40, so that the position stability of the second limiting shaft 802 can be enhanced, and the stability of the position of the second connecting rod 80 when the second air deflector 40 is at the maximum opening angle can be enhanced.

As shown in fig. 14, the first limiting shaft 702 is adapted to the first limiting groove 9011, and the first limiting groove 9011 extends along the opening direction of the first air deflector 30.

The second limiting shaft 802 is adapted to the second limiting groove 9021, and the second limiting groove 9021 extends along the opening direction of the second air deflector 40. In this way, in the opening process of the second air deflector 40, the second limiting shaft 802 is located in the second limiting groove 9021 and can move relative to the second limiting groove 9021, and the second limiting groove 9021 plays a guiding role on the second limiting shaft 802 to guide the second limiting shaft 802 to move steadily, so as to guide the second air deflector 40 to open steadily.
