[0028] Please refer to Figure 1-6 As shown, a lightweight automobile air deflector comprises a rotating shaft base 1 and a bottom support cross frame 5 which is arranged and installed on the back plate of the rotating shaft base 1 support in a vertically symmetrical form. A plurality of upper air deflectors 3 are arranged and connected inside the support of the rotating shaft base 1. The upper air deflector 3 comprises a deflector plate 31. A rotating shaft 32 which is rotatably connected to the rotating shaft base 1 is arranged at the bottom of the plate frame of the deflector plate 31. A rotating shaft groove 7 which is rotatably connected to the rotating shaft 32 is provided inside the support of the rotating shaft base 1. By utilizing the rotating shaft groove 7 on the rotating shaft base 1 to be connected with the rotation of the rotating shaft 32 on the upper air deflector 3, the upper air deflector 3 can have a downward pressure swinging performance. When the upper air deflector 3 is subjected to a large lateral wind resistance, the upper air deflector 3 is elastically swung downward under the elastic support of the buffer bracket 6, thereby reducing its lateral wind resistance area, thereby reducing the air resistance.

[0029] Side air guide covers 4 that fit with the upper air guide covers 3 on the outermost sides are symmetrically arranged on both sides of the rotating shaft base 1. The side air guide covers 4 include accordion plates 41. Air guide wing plates 42 are arranged between the folding seams of the accordion plates 41. The accordion plates 41 are fan-shaped structures, and the air guide wing plates 42 are V-shaped structures. Both the accordion plates 41 and the air guide wing plates 42 are engineering plastic components. By setting the side air guide covers 4 to engineering plastic materials, they have better deformation properties and can be synchronously extruded and deformed with the downward pressure of the buffer bracket 6. At the same time, the hook-shaped groove formed by the extrusion and folding of the air guide wing plates 42 is used to guide the air.

[0030] A plurality of bottom support vertical frames 8 are arranged on one side of the bracket of the bottom support horizontal frame 5. The upper end of each bottom support vertical frame 8 is provided with a buffer bracket 6 of the top support upper air guide cover 3. The buffer bracket 6 includes two vertically opposite groups of vertical sleeves 61 and two obliquely opposite groups of oblique sleeves 64. A vertical compression rod 62 is plugged in and connected between the two groups of vertical sleeves 61, and both ends of the arm of the vertical compression rod 62 are provided with a vertical buffer spring 63 elastically connected to the vertical sleeve 61. An oblique compression rod 65 is plugged in and connected between the two groups of oblique sleeves 64, and both ends of the arm of the oblique compression rod 65 are provided with a vertical buffer spring 63 elastically connected to the vertical sleeve 61. The elastically connected oblique buffer spring 66, the vertical sleeve 61 and the vertical compression rod 62 are all provided with a rotating shaft seat at the upper and lower ends of the sleeve seat. By utilizing the vertical buffer spring 63 to elastically support the vertical sleeve 61 and the vertical compression rod 62, and the oblique buffer spring 66 to elastically support the oblique sleeve 64 and the oblique compression rod 65, the buffer bracket 6 plays an elastic supporting role on the upper air guide cover 3. On the one hand, it serves as an arm force bracket to support the upper air guide cover 3 and guide the air. On the other hand, it serves as an elastic bracket to elastically swing support the upper air guide cover 3, thereby reducing its lateral wind receiving area and reducing air resistance.

[0031] A front protrusion 2 is provided at the front end of the support of the rotating shaft base 1. By providing the front protrusion 2 at the front end of the rotating shaft base 1, it has an air piercing function, thereby improving the air flow guiding performance of the air guide cover.

[0032] The working principle of the utility model is as follows: when the automobile air deflector is installed and used, the air deflector is mounted on the roof of the automobile, and the combination of the upper air deflector 3 and the side air deflector 4 is used to play an air deflection function, and in the process of air deflection, the upper air deflector 3 can be made to have a downward pressure swinging performance by utilizing the rotation of the rotating shaft base 1 connected to the upper air deflector 3, and then when the upper air deflector 3 is subjected to a large lateral wind resistance, the upper air deflector 3 is elastically swung and pressed down under the elastic support of the buffer bracket 6, thereby reducing its lateral wind resistance area and playing a role in reducing air resistance, and synchronously by setting the side air deflector 4 to an engineering plastic material, it can be extruded and deformed synchronously with the downward pressure of the buffer bracket 6, and at the same time, the hook-shaped groove formed by the extrusion and folding of the guide wing plate 42 thereof is used to play a diversion role, and its overall structure has lightweight installation characteristics, and can dynamically guide air in real time according to the size of the wind resistance, so as to ensure the best diversion effect of the air deflector.
