Description

Technical Field

[0001] This utility model relates to the field of commercial vehicle exterior technology, and in particular to the corner spoiler structure of commercial vehicle sunshade, cab assembly and commercial vehicle. Background Technology

[0002] As an important exterior component on the top of the cab, the sun visor of a commercial vehicle directly affects the vehicle's fuel economy and driving stability due to its aerodynamic performance.

[0003] Airflow separation and turbulence at the outer corner of the sun visor are among the key factors affecting the aerodynamic performance of the entire vehicle.

[0004] The sunshade of a commercial vehicle is located directly above the windshield, and the aerodynamic noise it generates directly affects the driver's subjective experience. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a corner spoiler structure for commercial vehicle sunshades, adding strip-shaped spoilers to break up large vortex airflow at the corner. Taking into account both spoiler performance and aesthetics, the corner strip-shaped spoiler is arranged to fit the tail corner shape without affecting the integration of components such as lights, thereby achieving the goal of improving aerodynamic performance.

[0006] This utility model proposes a corner spoiler structure for commercial vehicle sunshades, including a commercial vehicle sunshade. The commercial vehicle sunshade has an overall horizontal U-shaped structure. At least two spoiler strips protrude from the outer side of each corner of the U-shaped commercial vehicle sunshade. The spoiler strips at the corner positions can break up the large vortex airflow at the corner positions.

[0007] The commercial vehicle sunshade includes a front wall that is bent into a U-shape and a left side wall and a right side wall respectively disposed at both ends of the front wall. The deflector strips extend from the lower end of the outer surface of the front wall to the upper outer surface of the corresponding left side wall or the upper outer surface of the right side wall, and the upper ends of all the deflector strips are on the same horizontal plane. The inclined deflector strips play a dual role in guiding and breaking the airflow at the corner position.

[0008] The spoilers are arranged at equal intervals or with increasing spacing from front to back, and the adjacent spoilers are parallel to each other. The spacing between the two adjacent spoilers is 18mm-22mm; or, the spacing between the two adjacent spoilers arranged with increasing spacing from front to back increases by 5mm; the length of each spoiler is 100mm-150mm.

[0009] The adjacent spoilers have a diverging line structure, meaning that the angle between the extended lines of the lower ends of two adjacent spoilers is 5-15°, and the length of the rear spoiler of the two adjacent spoilers is greater than the length of the front spoiler.

[0010] Each spoiler strip is fitted to the corner outer surface of the commercial vehicle sun visor in an arc shape.

[0011] Each spoiler has a cross-section that is an outward-protruding arc surface; or, each spoiler has a cross-section that is a triangular structure; or, each spoiler has a cross-section that is a trapezoidal structure.

[0012] The upper outer wall of each corner of the commercial vehicle sun visor has a sun visor marker light mounting hole, and the sun visor marker light is matched and fitted into the sun visor marker light mounting hole.

[0013] The lower rear ends of the left and right side walls of the commercial vehicle sun visor are rounded, and the front wall of the commercial vehicle sun visor has a backward tilt angle with the vertical plane, the angle being 15-20°.

[0014] The commercial vehicle cab assembly includes cab sheet metal and a windshield, and also includes the aforementioned commercial vehicle sun visor corner spoiler structure, which is mounted and fixed on the cab sheet metal above the windshield.

[0015] Commercial vehicle, including the aforementioned commercial vehicle cab assembly.

[0016] Beneficial effects

[0017] This invention adds strip-shaped deflectors to break up the large vortex airflow at the corner position. Taking into account both deflection performance and aesthetics, the corner strip-shaped deflector is arranged to fit the tail corner shape without affecting the integration of components such as lamps, thereby achieving the purpose of improving aerodynamic performance.
