A front bumper deflector for a truck

By designing a combination structure of slightly inclined or horizontal extension plates and angled guide plates at the lower part of the truck's front bumper, combined with rubber materials and steel sheet reinforcement, the shortcomings of existing truck deflectors in terms of wind resistance and passability are solved, achieving a low-cost and efficient wind resistance reduction effect.

AI Technical Summary

Technical Problem

Existing truck front bumper deflectors are inadequate in reducing wind resistance and maintaining passability, and their complex structure and high cost make them difficult to apply effectively in various road conditions.

Method used

Design a slightly inclined or horizontal extension plate extending rearward from the lower part of the front bumper and a deflector extending obliquely downward and backward, combining rubber material and pre-embedded steel sheet structure. The angle between the lower surface of the deflector and the horizontal plane is 20° to 70°, and flexible materials are used to adapt to different road conditions.

Benefits of technology

It achieves a significant reduction in drag coefficient without affecting approach angle and minimum ground clearance, improves the durability of the deflector and reduces costs, while avoiding damage under extreme conditions.

Abstract

This utility model discloses a front bumper under-airflow deflector for trucks, comprising an extension plate extending slightly downward and backward at a certain angle or horizontally from the mounting point at the lower part of the front bumper, and a deflector plate extending obliquely downward and backward at a certain angle. The deflector plate and the extension plate have a rounded transition. The lower surface of the deflector plate is flat or a single curved surface. The angle between the tangent direction of the lower surface of the deflector plate extending to its lower edge and the horizontal plane is 20°–70°. The length of the deflector plate itself is 30–100 mm. This under-airflow deflector is made of rubber, with a steel sheet pre-embedded at the mounting point or a thin steel sheet sandwiched in the middle of the entire under-airflow deflector. This utility model guides airflow from a lower position into the undercarriage, reducing the resistance caused by airflow directly blowing onto the chassis and wheels, thereby reducing the overall drag coefficient and fuel consumption. It also solves the problem of insufficient strength, easy damage, and impact on passability and approach angle caused by large deflector plates.
