Resistance-reducing self-adaptive universal type flow guide cover and control method thereof

Abstract

The invention discloses a resistance-reducing self-adaptive universal type flow guide cover. The resistance-reducing self-adaptive universal type flow guide cover comprises a first flow guide plate, a second flow guide plate, a first width adjusting device, a second width adjusting device and a height adjusting device, wherein the first flow guide plate is arranged at the top of the flow guide cover; one end of the first flow guide plate is connected with the top of a first side fence plate; a clamping block is arranged at the bottom of the other end of the first flow guide plate; a sliding groove is formed in the top of one end of the second flow guide plate; the sliding groove can be matched with the clamping block of the first flow guide plate; the other end of the second flow guide plate is connected with the top of a second side fence plate; the second flow guide plate can slide relative to the first flow guide plate; one end of the first width adjusting device is fixed on the first side fence plate and the other end of the first width adjusting device is fixed on a first center bearing; one end of the second width adjusting device is fixed on the second side fence plate and the other end of the second width adjusting device is fixed on a second center bearing; and one end of the height adjusting device is fixed at the top in the flow guide cover and the other end of the height adjusting device is fixed at the top of an automobile cab, so that the height of the flow guide cover can be adjusted. The resistance-reducing self-adaptive universal type flow guide cover can be adjusted in height and width and is suitable for different vehicles.

Description

technical field [0001] The invention relates to a wind deflector, in particular to a drag reduction self-adaptive general wind deflector and a control method thereof. Background technique [0002] Good vehicle aerodynamic design is an important way to improve vehicle dynamics, safety and economy. However, because the car body is generally higher than the cab, the flow field of the vehicle is discontinuous and the flow linearity is poor. When the car is running at high speed, when the airflow above the cab meets the upper part of the front part of the closed compartment, a large circumvention flow will be generated from the front edge of the compartment roof, and the value of the air resistance coefficient will increase accordingly. It seriously affects the fuel economy, and because of the different models of cars, there are various forms of car spoilers, which require different types of car spoiler molds during manufacture, and the manufacturing cost increases. The height ...
