Description

Technical Field

[0001] The utility model relates to the field of decorative panel covers, and particularly to a front windshield lower decorative panel cover for reducing wind noise in an automobile. Background Art

[0002] With the improvement of living standards, people's pursuit of quality of life is getting higher and higher. Off-road vehicles have received more and more attention. The boxy shape is basically the logo of off-road vehicles. The whole vehicle with this shape has hard lines. The airflow conformity at the hood, A-pillar, rearview mirror, etc. is poor, resulting in relatively large interior noise and affecting the comfort of passengers.

[0003] In the past, the research on automobile wind noise mainly focused on the A-pillar and rearview mirror, and less attention was paid to other parts. However, in fact, the factors affecting interior noise are not only the above two places. Through CFD analysis, it is found that the front windshield lower decorative panel on the outer side of the front end of the front windshield also has a greater impact on wind noise. The conformity of the airflow flowing through the hood and fender can be increased by improving the structure of the front windshield lower decorative panel, and the wind noise can be improved. Content of the Utility Model

[0004] The purpose of the utility model is to provide a front windshield lower decorative panel cover for reducing wind noise in an automobile, so as to solve the problems put forward in the above background art.

[0005] To solve the above technical problems, the utility model provides the following technical solution: A front windshield lower decorative panel cover for reducing wind noise in an automobile, including two covers, which are respectively installed on the left and right sides of the rear part of the engine cover, the front part of the front windshield, and the upper part of the front windshield lower decorative panel;

[0006] Each cover includes a wind guiding surface, a wind guiding surface fillet, a top surface, an air outlet surface fillet, and an air outlet surface; the wind guiding surface is located on one side of the cover, and the air outlet surface is located on the other side of the cover and contacts the automobile fender;

[0007] The air outlet surface fillet is located between the cover and the air outlet surface, and the wind guiding surface fillet is located between the wind guiding surface and the cover,

[0008] The wind guiding surface is an inclined surface, and the radii of the wind guiding surface fillet and the air outlet surface fillet are greater than 15 mm.

[0009] Preferably, the two covers are mirror symmetric.

[0010] Preferably, mounting buckles are also fixedly arranged on the cover.

[0011] Preferably, the included angle between the wind guiding surface and the top surface is greater than 120 degrees.

[0012] Preferably, 6 mounting buckles are provided.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] By improving the angle inside the cover plate and the top fillet, the present utility model increases the conformity of the air flow when passing through the cover plate, guides the air flow to flow from the door panel below the side window, reduces the impact of the air flow on the side window, and thus reduces the interior noise of the vehicle. The structure is simple, and the optimization and adjustment of the inner side angle and the top fillet of the wind noise can be achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-3 , this embodiment provides a front windshield lower trim cover plate for reducing wind noise in an automobile, including two cover plates, a left cover plate 1 and a right cover plate 2, which are mirror-symmetrically distributed. Each cover plate includes a wind guiding surface 3, a wind guiding surface fillet 4, a top surface 5, an air outlet surface fillet 6, an air outlet surface 7, and an installation buckle 8. As Figure 1 shown, the wind guiding surface 3 is located on one side of the cover plate, and the air outlet surface 7 is located on the other side of the cover plate. The air outlet surface 7 and the wind guiding surface 3 are located on the symmetric sides of the cover plate. The air outlet surface 7 is located on the outside of the automobile and contacts the fender 12 of the automobile, as Figure 3As shown in the figure. The air guiding surface 3 is an inclined surface, and the included angle with the top surface 5 is greater than 120 degrees). The air guiding surface fillet 4 is located between the air guiding surface 3 and the cover plate, and the radius of the air guiding surface fillet 4 is greater than 15 mm. The air outlet surface fillet 6 is located between the cover plate and the air outlet surface 7, and the radius of the air outlet surface fillet 6 is greater than 15 mm. The top surface 5 is designed according to the engine cover, and the air outlet surface 7 is designed according to the engine cover and the fender surface (the top surface is flush with the engine cover, the fillet of the outer side edge line is flush with the fillet of the engine cover edge line, and the air outlet surface is flush with the fender). There are 6 installation buckles 8 fixedly arranged at the bottom of the cover plate. The cover plate is installed on the lower decorative plate 9 of the front windshield through the installation buckles 8. The installation through the buckles is simple and reliable. The slope of the air guiding surface 3 and the sizes of the air guiding surface fillet 4 and the air outlet surface fillet 6 can be adjusted according to the CFD analysis results. The number and structure of the installation buckles 8 can be adjusted according to the layout space. By improving the angle inside the cover plate and the top fillet, the conformability of the air flow when flowing through the cover plate is increased, the air flow is guided to flow from the door panel below the side window, and the impact of the air flow on the side window is reduced, thereby reducing the interior noise of the vehicle. All hardcore off-road vehicles can be used for reference to improve the wind noise problem.

[0020] For the installation of the cover plate, see Figure 3 . The cover plate 1 is installed above the lower decorative plate 9 of the front windshield, behind the engine cover 10, in front of the front windshield 11, and above the fender 12. The installation orientation of the cover plate 2 is mirror to that of the cover plate 1.

[0021] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
