Automobile active air-intake grille

Abstract

Provided is an automotive active air-intake grille. The automobile active air-intake grille includes a grille frame and a plurality of air-intake blades; a driving motor is disposed on the middle of the grille frame, and the air-intake blades are divided into two groups and are separately located on both sides of the driving motor; an output shaft of the driving motor is connected with a central control rotating shaft, two sides of the central control rotating shaft are extended with rotating arms, the ends of the rotating arms are rotatably connected with pull rods, and the ends of the pull rods are rotatably connected with an adjacent air-intake blade or one end of a connecting rod; and each air-intake blade is provided with an eccentric shaft, the eccentric shafts of the air-intake blades on the same side are connected with the same connecting rod in a rotation mode. The automobile active air-intake grille has the beneficial effects that an opening angle of the air-intake blades canbe adjusted according to the temperature of an engine, thereby improving the working efficiency of the engine, saving oil and reducing emissions; the power of the driving motor is transmitted to theair-intake blades through the central control rotating shaft, the pull rods and the connecting rods, so that the air-intake blades are turned over to open or close; and the transmission is simple andthe work is reliable.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile active air intake grille. Background technique [0002] The main function of the car air intake grille is to provide air intake channels for the car engine, so that the car can dissipate heat in time. When the water temperature of the engine radiator is too high and cannot be fully dissipated by natural wind alone, the fan will start to assist in heat dissipation. The air in the middle flows backwards, and the airflow direction of the fan is also backwards. The car air intake grille provides the air intake channel for the car, so that the external air enters the car body and forms a passage. [0003] The air intake grille of the prior art is fixed together with the front bumper, and the air intake grille is always in an open state, and cannot be opened and closed with the temperature of the engine compartment, so it cannot make the automobile engine achieve Opt...
