[0054] Moreover, in the light shielding state, the light shielding piece 2 can be supported on the second arc-shaped windshield panel 3, and the falling degree is small, which has little effect on the vehicle interior space.

The vehicle window is located at the top of the vehicle, that is, the vehicle air baffle structure in some embodiments of the present disclosure is used as a sunroof.

[0061] By making the shading piece 2 supported on the second arc-shaped air baffle 3 in the vertical direction in the shading state, on the one hand, the second arc-shaped air baffle 3 can limit the shading piece 2 in the shading state, and the shading piece 2 is not easy to shake relatively to the first arc-shaped air baffle 1 and the second arc-shaped air baffle, which is conducive to improving the shading effect; on the other hand, the shading piece 2 has a small sagging distance under the action of gravity, that is, the spacing between the shading piece 2 and the first arc-shaped air baffle 1 is small, and the shading piece 2 is relatively close to the first arc-shaped air baffle 1, which is conducive to improving the shading effect.

In this structure, the shading piece 2 moves along the extension direction of the second arc-shaped air baffle 3 to switch between the shading state and the opening state, and the switching of the shading piece 2 between the shading state and the opening state is relatively convenient.

[0064] For example, please refer to FIG. 1 and FIG. 2, the vehicle window is located at the top of the vehicle, the thickness direction of the second arc-shaped air baffle 3 is the vertical direction, and the first direction a is the horizontal direction, which can be the length direction or the width direction of the vehicle, etc.

[0065] Please refer to FIG. 1 and FIG. 2, in some embodiments of the present disclosure, the movement path of the light shielding member 2 relative to the first arc-shaped wind deflector 1 matches the extension path of the second arc-shaped wind deflector 3 towards one side of the first arc-shaped wind deflector 1. In this way, it is beneficial to reduce the space occupied by the light shielding member 2 in the thickness direction of the second arc-shaped wind deflector 3 during the movement of the light shielding member 2 relative to the first arc-shaped wind deflector 1.

[0066] Please refer to FIG. 3 and FIG. 6, in some embodiments of the present disclosure, the first arc-shaped wind deflector 1 has at least one first cross section perpendicular to the first direction a, and the second arc-shaped wind deflector 3 has at least one second cross section coplanar with the first cross section, the first cross section extends along a first arc line, and the second cross section extends along a second arc line d.

[0067] The first arc line and the second arc line d satisfy the following conditions: the midpoint of the first arc line, the midpoint of the second arc line d, the center of curvature of the first arc line at the midpoint, and the center of curvature of the second arc line d at the midpoint are collinear.

[0073] Please refer to FIG. 3 and FIG. 6, in some embodiments of the present disclosure, the curvature of the second arc d at the middle point is less than or equal to the curvature of the first arc at the middle point. In this structure, along the extension direction of the second arc d, the distance between the edge of the second arc-shaped wind deflector 3 and the first arc-shaped wind deflector 1 in the thickness direction is smaller, which is conducive to improving the compactness of the vehicle wind deflector structure, thereby facilitating the improvement of the passenger space, and the distance between the middle of the second arc-shaped wind deflector 3 and the first arc-shaped wind deflector 1 in the thickness direction is larger, which is conducive to improving the smoothness of the switch between the shading state and the open state of the shading piece 2.

[0074] In some embodiments of the present disclosure, the curvature of the second arc d outwardly curved is less than or equal to the curvature of the first arc outwardly curved. It can be understood that the curvature of the second arc d outwardly curved is less than or equal to the curvature of the first arc outwardly curved refers to the description under the condition that the relative positions of the first arc-shaped wind deflector 1 and the second arc-shaped wind deflector 3 are determined.

[0075] In this structure, along the extension direction of the second arc d, the distance between the edge of the second arc-shaped wind deflector 3 and the first arc-shaped wind deflector 1 in the thickness direction is smaller, which is conducive to improving the compactness of the vehicle wind deflector structure, thereby facilitating the improvement of the passenger space, and the distance between the middle of the second arc-shaped wind deflector 3 and the first arc-shaped wind deflector 1 in the thickness direction is larger, which is conducive to improving the smoothness of the switch between the shading state and the open state of the shading piece 2.

[0076] In some embodiments of the present disclosure, the curvature of the second arc d outwardly curved is less than or equal to the curvature of the first arc outwardly curved.

[0077] In this structure, along the extension direction of the second arc d, the distance between the edge of the second arc-shaped wind deflector 3 and the first arc-shaped wind deflector 1 in the thickness direction is smaller, which is conducive to improving the compactness of the vehicle wind deflector structure, thereby facilitating the improvement of the passenger space, and the distance between the middle of the second arc-shaped wind deflector 3 and the first arc-shaped wind deflector 1 in the thickness direction is larger, which is conducive to improving the smoothness of the switch between the shading state and the open state of the shading piece 2.

[0078] Moreover, in this way, along the first direction, the second arc-shaped wind deflector 3 is relatively flat, which is conducive to reducing the interference between the shading piece 2 and the second arc-shaped wind deflector 3 during the movement of the shading piece 2 relative to the second arc-shaped wind deflector 3.

[0079] In some embodiments of the present disclosure, the position of the first arc with the smallest curvature outwardly curved to the vehicle is referred to as the third position N.

[0080] In some embodiments of the present disclosure, at the corresponding position, the curvature of the second arc is less than or equal to the minimum curvature of the first arc. In other words, when the second arc and the first arc are not circular arcs, the curvature of the second arc is not a single value, but multiple values, and the curvature of the first arc is not a single value, but multiple values.

[0081] The comparison at the position (the curvature of the second arc is less than or equal to the minimum curvature of the first arc) refers to the curvature at the corresponding position when the relative positions of the first arc-shaped air baffle 1 and the second arc-shaped air baffle 3 are determined. The corresponding position refers to the intersection line of the cross sections along the first direction a and the second direction b in FIG. 3, the point where the intersection line intersects the second arc, and the point where the intersection line intersects the first arc. When the second arc and the first arc are circular arcs, the curvature of the second arc is a single value, and the curvature of the first arc is a single value.

[0082] Please refer to FIGS. 3, 4, 5 and 6. In some embodiments of the present disclosure, the edges of the second arc-shaped air baffle 3 in the second direction b are each equidistant from the edges of the first arc-shaped air baffle 1 in the third direction c. The straight line where the midpoint of the first arc and the midpoint of the second arc d are located is parallel to the third direction c. The second direction b, the first direction a and the third direction c are orthogonal to each other.

[0083] With this structure, the edges of the second arc-shaped air baffle 3 in the second direction b are consistent in shape with the edges of the first arc-shaped air baffle 1, and the positions of the undulations correspond. The edges of the second arc-shaped air baffle 3 and the edges of the first arc-shaped air baffle 1 can be arranged closely, which is conducive to improving the compactness of the vehicle air baffle structure, thereby improving the interior space of the vehicle.

In some embodiments of the present disclosure, the third cross section of the second arc-shaped air baffle 3 extends along a third arc e, the third cross section is perpendicular to the second direction b, and the third arc e protrudes outwardly from the vehicle.

[0088] In this structure, the first arc-shaped air baffle 1 protrudes outward to a greater extent, which is conducive to further increasing the interior space. It can be understood that, on this basis, the edge of the second arc-shaped air baffle 3 in the second direction b is equal in distance to the first arc-shaped air baffle 1 in the third direction c at each position, that is, the third arc line e at the edge of the second arc-shaped air baffle 3 in the second direction b is the same as the corresponding fourth arc line.
