AI Technical Summary
Traditional fairings have a non-adjustable tilt angle, making them unsuitable for different container heights, resulting in increased wind resistance or poor airflow.
Design a tilt height adjustable air guide shroud. Through the rotational cooperation of the circular tube and the arc groove, the angle of the air guide plate can be infinitely adjusted. Combined with the pressure plate-brake pad locking and the inner shaft limit structure, the stability of the air guiding effect is ensured.
It enables precise adjustment of the air guide plate angle according to the height of the container, minimizing wind resistance, simplifying operation, and preventing angle deviation during vibration, thus improving the reliability and stability of the device.

Abstract
Claims
1. A semi-trailer deflector cap to reduce wind resistance, characterized in that, include: The base is fixedly installed on the top of the front of the semi-trailer. A wind-guiding slope is provided on the end face of the base facing the direction of vehicle travel. An arc-shaped groove is provided on the position of the base away from the direction of vehicle travel. The arc of the arc-shaped groove is greater than 1π. Two or more T-shaped grooves are provided on the top of the base. The T-shaped grooves extend in a direction away from the arc-shaped groove. A rear baffle is fixed on the end of the base away from the direction of vehicle travel. The rear baffle closes the T-shaped grooves. An air guide plate, one end of which is provided with a circular tube portion, which is rotatably mounted within the arc-shaped groove. A pressure plate is provided with an arc-shaped opening on one side and a force-bearing rod on the other side. A T-shaped block that matches the T-shaped groove is provided at the bottom of the force-bearing rod. The arc-shaped opening and the arc-shaped groove are spliced together to form an open groove. The arc of the open groove is less than 1π so that the circular tube part is confined within the arc-shaped groove. A force-operating screw is provided on the surface of the rear baffle, corresponding to the force-bearing rod. After the force-operating screw passes through the screw hole, it acts on the force-bearing rod, so that the pressure plate is displaced in the direction of the arc groove and clamps the round tube.
2. The reduced wind resistance semi-trailer deflector shield of claim 1, wherein: A stepped hole is vertically machined on the air guide slope, and a rubber plug is detachably installed at the opening of the stepped hole.
3. The reduced wind resistance semi-trailer deflector shield of claim 2, wherein: A frame-shaped filling groove is machined at the bottom of the base, and the stepped hole is located inside the filling groove.
4. The reduced wind resistance semi-trailer deflector shield of claim 1, wherein: A brake pad is fixed to the inner wall of the arc-shaped opening, and the circular tube is braked by the brake pad.
5. The reduced wind resistance semi-trailer deflector shield of claim 4, wherein: An inner shaft is provided at the center of the cylindrical section. Second stepped holes corresponding to the inner shaft are provided at both ends of the base. Both ends of the inner shaft are inserted into the second stepped holes. Internal threaded holes are machined at both ends of the inner shaft. End limiting screws are assembled at both ends of the inner shaft through the internal threaded holes. After the end limiting screws are screwed in, they act on the stepped surface of the second stepped hole to limit the axial displacement of the inner shaft.
