Embodiment 1

[0042] see Figure 1 to Figure 3 According to an embodiment of the present invention, an automobile spoiler device capable of reducing wind resistance, the automobile spoiler device includes a flexible variable front bumper, a flexible variable rear bumper and an inflation control device.

[0043] Wherein, the flexible variable front bumper is arranged on the front end of the car, including a bumper body and a first inflatable airbag 1 arranged in front of the bumper body, and a second inflatable airbag 2 arranged in the first inflatable airbag 1, The first inflatable airbag 1 is a conical airbag whose middle part protrudes forward.

[0044] The flexible and variable rear bumper is arranged on the rear end of the automobile, including the bumper body and the third inflatable airbag 6 arranged behind the bumper body (wherein, the "front" and "rear" are referenced to the automobile. In other words, the direction pointed by the front of the car is the front, and the direction po...

Embodiment 2

[0054] A car spoiler that can reduce wind resistance is the same as the first embodiment. In this embodiment, the same flexible variable front bumper and flexible variable rear bumper are provided.

[0055] The flexible and variable front bumper is arranged on the front end of the car, including a bumper body and a first inflatable air bag arranged in front of the bumper body, and a second inflatable air bag arranged in the first inflatable air bag. The airbag is a conical airbag protruding forward in the middle;

[0056] The flexible and variable rear bumper is arranged at the rear end of the car, including a bumper body and a third inflatable air bag arranged behind the bumper body, and a fourth inflatable air bag arranged in the third inflatable air bag. The inflatable air bag is a conical air bag protruding backward in the middle.

[0057] The difference from Embodiment 1 is that the automobile spoiler device of this embodiment is only suitable for automobiles with turboc...

Abstract

The invention discloses an automobile turbulence device capable of reducing wind resistance. The automobile turbulence device comprises a flexible variable front bumper, a flexible variable rear bumper and an inflation control device. The flexible variable front bumper is arranged at the front end of an automobile, and comprises a bumper body, a first inflation air bag arranged in front of the bumper body, and a second inflation air bag arranged in the first inflation air bag. The flexible variable rear bumper is arranged at the rear end of the automobile and comprises a bumper body, a third inflation air bag arranged behind the bumper body, and a fourth inflation air bag arranged in the third inflation air bag. The inflation control device comprises a controller, an air storage cylinder and solenoid valves. The first inflation air bag, the second inflation air bag, the third inflation air bag and the fourth inflation air bag are all connected to the air storage cylinder through the solenoid valves. According to the automobile turbulence device, the running wind resistance of the automobile can be effectively reduced, and the utilization rate of automobile fuel can be increased.

Description

technical field [0001] The invention relates to the field of automobile structures, in particular to an automobile spoiler capable of reducing wind resistance. Background technique [0002] Body styling design is a big science, and the focus is on body weight, structural strength and wind resistance. Automobile wind resistance mostly refers to the resistance produced by the exterior of the automobile and the airflow. In fact, the airflow flowing through the interior of the car also constitutes resistance to the driving of the car. Studies have shown that the resistance acting on the car is composed of 5 parts. [0003] 1. External resistance refers to the resistance formed by the difference between the positive pressure at the front of the car and the negative pressure at the rear of the car body, accounting for about 58% of the entire air resistance; [0004] 2. Interference resistance refers to the resistance caused by the mutual interference of airflow caused by parts ...
