Abstract

The invention discloses an automobile turbulence device capable of improving the fuel economy. The automobile turbulence device comprises a flexible and changeable front bumper, a flexible and changeable rear bumper and an air inflation control device; the flexible and changeable front bumper is arranged at the front end of an automobile and comprises a bumper body, 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 flexible and changeable rear bumper is arranged at the rear end of the automobile and comprises a bumper body, a third inflatable air bag arranged in the back of the bumper body and a fourth inflatable air bag arranged in the third inflatable air bag; the air inflation control device comprises a controller, an air storage bottle and solenoid valves, and the first inflatable air bag, the second inflatable air bag, the third inflatable air bag and the fourth inflatable air bag are connected to the air storage bottle through the solenoid valves. According to the invention, the driving wind resistance of the automobile can be effectively lowered, and the fuel utilization efficiency the automobile can be improved.

Description

technical field [0001] The invention relates to the field of automobile structures, in particular to an automobile spoiler capable of improving fuel economy. 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 pr...
