Problems solved by technology

However, the existence of the rear spoiler will inevitably form a certain low-pressure area behind the rear window of the car, which increases the pressure difference resistance encountered by the vehicle during driving, especially during high-speed driving. The increase in fuel consumption is more significant.

Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0015] The hollowed-out SUV rear spoiler that can reduce drag and lift in the present invention is a U-shaped plate structure made of reinforced plastic material as a whole; the left and right sides transition from vertical arcs to the rear side, and the arc of the arc is 90 degrees. The left and right end faces are equal-sized installation surfaces 1, and the length of the installation surface 1 in the left and right directions is a, where a>5cm. The specific value depends on the overall design length of the rear spoiler. The recess 2 in the middle of the rear side is rectangular, the long side is along the left and right direction, the length is 5a, and the width is a / 2. In the rear spoiler with the above structure, the left and right end faces and the middle part are recessed to fix it with the car body, and the design of the recess can greatly reduce the ...

Abstract

The invention discloses a hollow-out SUV rear spoiler that can reduce drag and lift. A rectangular hole is opened in the middle of the rear spoiler to allow airflow to flow directly through the rectangular hole, thereby reducing the low pressure behind the rear window of the vehicle. zone, reducing the pressure differential resistance encountered by the vehicle during driving. At the same time, the cross-section of the spoiler behind the rectangular hole is designed as an inverted airfoil to compensate for the downforce loss caused by the opening, so as to ensure that the pressure difference resistance is reduced while not affecting the rise of the rear spoiler on the vehicle. The counteracting effect that the force should have.

Description

technical field [0001] The invention belongs to the field of SUV rear spoilers, in particular to a hollow-out SUV rear spoiler capable of reducing resistance and lifting. Background technique [0002] It can be seen that in recent years, SUV cars have become more and more popular in cities, and almost all the rear windows of SUV cars have an extra section protruding from the top of the car, which is the rear spoiler. Because the car body is usually an irregular streamlined body, when the air flows through, it will inevitably generate upward lift like a wing. The function of adding a rear spoiler is to generate downforce without significantly increasing the weight of the car body. , Offset a part of the lifting force suffered by the vehicle during driving, prevent the vehicle from over-steering, reduce the grip of the rear wheels, and improve the stability of the vehicle. At the same time, the rear spoiler can also enhance the dynamism and beauty of the car, reflecting the p...
