Automobile active air inlet grille

Abstract

The invention discloses an automobile active air inlet grille, including a grille frame, driving grille blades, driven grating blades, a driving mechanism and a transmission link. the two ends of thedriving grille blades and the driven grille blades are rotationally connected with the grille frame; the driving mechanism is in transmission connection with the driving grille blades; linkage shaftsare arranged at the ends, close to the transmission connecting rods, of the driving grating blades and the driven grating blades in a protruding mode, inserting holes are formed in the transmission connecting rods, and the linkage shafts are inserted into the inserting holes, so that when the driving grating blades are driven by the driving mechanism to turn over, the driving grating blades drivethe transmission connecting rods to rotate, and then the transmission connecting rods drive the driven grating blades to turn over. The automobile active air inlet grille has good aerodynamic performance, the wind resistance of the whole vehicle is reduced, the engine is at the optimal level temperature, energy consumption is reduced, and the automobile active air inlet grille is more environmentally friendly, simpler and more reasonable in structure, convenient to assemble and lower in cost.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an active air intake grille for an automobile. Background technique [0002] The air intake grille of ordinary models cannot be closed actively. When the cold car is just started, the air will also cool down the water tank, which is not too hot, so that the water temperature rises slowly, and the engine cannot quickly enter the optimal working temperature. [0003] The active air intake grille can change the opening and closing of the air intake grille to control the air intake volume and wind resistance, thereby improving fuel economy and quickly reaching the optimum operating temperature of the engine. Advantages of active air intake grille: 1. When the vehicle is cold, the grille is closed, which is conducive to the engine quickly entering a better temperature state; 2. After the grille is opened, it can reduce air resistance to a certain extent while dissipating heat. Thereby impr...

AI Technical Summary

Problems solved by technology

[0005] Due to the large area of ​​the air intake area of ​​the car, multiple grille vanes need to be set up. Each grille vane of the existing active air intake grille of the car uses an active grille vane, so it is necessary to connect the drive mechanism, and also requires multiple grille vanes. Small drive mechanism or customized large drive mechanism, which has higher requirements on the structure of parts and components, and the structure is more complicated, resulting in an increase in production costs
