Sliding type driving air inlet grid structure

Abstract

The invention relates to a sliding type driving air inlet grid structure which comprises a plurality of blades, a sliding mechanism and a driving device, wherein the blades are sequentially connected up and down through the sliding mechanism; the lowest blade is connected with the driving device; the driving device is connected with an automobile ECU; the automobile ECU controls the driving device to drive the lowest blade connected with the driving device to move up and down; and the rest blades is driven by the sliding mechanism to move up and down along with the lowest blade to adjust the opening degree of the blades. The sliding type driving air inlet grid structure is compact in structure and ensures stable operation; and a lower air inlet grid is high in air inlet efficiency and has a low negative effect to a wind drag coefficient, so that the automobile air drag and the engine cooling efficiency have more reasonable combination.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a sliding active air intake grille structure. Background technique [0002] The car intake grille is located at the front of the engine compartment, including the upper intake grille and the lower intake grille. When the car is running, fresh air actively enters the engine compartment through the intake grille to ensure the normal operation of the engine cooling system. The active air intake grille can realize the active control of the air intake at the front end. During the driving process of the car, the active air intake grille is closed at the beginning of the car startup to reduce heat loss and improve the cold start performance of the car; close the active air intake grille at high speed The grille can improve the aerodynamic performance of the car, reduce the drag coefficient, and improve fuel consumption; in addition, the active air intake grille also has the functions of impro...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems existing in the active air intake grille in the prior art, the present invention provides a sliding active air intake grille structure. In the active air intake grille structure, the blades are continuously distributed, and the blades are from top to bottom when the air intake channel is closed. The bottom and bottom are carried out in sequence, which effectively avoids the defects of the existing active air intake grille structure in the actual application state due to the gaps in the blades, which are easy to enter the foreign matter and cause damage. The grille is more in line with the actual needs of car aerodynamics and car cooling system optimization
