front deflector

Abstract

The invention discloses a front flow guide device. The front flow guide device comprises a motor, a driving unit and a front flow guide plate unit, the motor drives the front flow guide plate unit tostretch out and draw back in the height direction through the driving unit, and the front flow guide plate unit is installed at the bottom of a front bumper. Since the front flow guide plate unit candrive the driving unit to achieve stretching out and drawing back in the height direction through the motor, according to factors of vehicle speed, road conditions and the like, the front flow guide plate unit can adjust the height from the ground, therefore, parts can be prevented from being damaged, more excellent passing performance is obtained, superior flow guide performance can also be obtained, and fuel economy and stability when a vehicle is driven are improved.

Description

Technical field [0001] The present invention relates to the field of automobiles, and in particular to a front flow guide device for a front bumper. Background technique [0002] Studies have shown that when the vehicle speed exceeds 60Km / h, air resistance will account for more than half of the total resistance. The aerodynamic resistance of a high-speed vehicle increases approximately in proportion to the square of the vehicle speed, that is, if the vehicle speed is doubled, the aerodynamic resistance will increase by four times and fuel consumption will increase accordingly. Therefore, the bottom of the front bumper of many cars is equipped with a diversion device, which can divert a certain amount of air to the sides and bottom of the vehicle, which can not only reduce the aerodynamic resistance of the vehicle, but also increase the air under the vehicle. Pressure to improve the aerodynamic performance and stability of the vehicle. [0003] However, after adding this device, o...

Problems solved by technology

[0003] However, after adding this device, on the one hand, the height from the ground is reduced, which reduces the passability of the vehicle, and it is easy to scratch during the use of the vehicle, causing parts to be damaged or even dropped, causing customers to complain; on the other hand, due to the height from the ground The height of the conventional front deflector is generally about 50mm

Research and experiments have shown that when the height of the deflector is around 100mm, the passage of the airflow is the best. Obviously, the conventional front deflector obviously does not exert its best effect
