Variable air inlet grille of automobile radiator

Abstract

The invention provides a variable air inlet grille of an automobile radiator, and belongs to the technical field of automobiles. The variable air inlet grille of the automobile radiator solves the technical problem that an existing automobile air inlet grille cannot be adjusted between the fully-opened state and the fully-closed state. The variable air inlet grille of the automobile radiator comprises a grille frame fixedly arranged at the front end of an automobile. A support is fixedly arranged in the grille frame, a plurality of grille pieces are evenly arranged on the support, and the middle of each grille piece is connected to the support in a rotary mode. The variable air inlet grille further comprises a plurality of connecting rods, each grille piece is hinged to the corresponding connecting rod, the grille pieces are parallel to one another, and when all the grille pieces are rotated onto the same plane, a frame opening of the grille frame can be covered. An adjusting structure which can be used for adjusting the angles between the grille pieces and the connecting rods is arranged on the support. The variable air inlet grille of the automobile radiator has the advantages of being simple in structure, capable of being adjusted between the fully-opened state and the fully-closed state and the like.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a variable air intake grille of an automobile radiator. Background technique [0002] In order to avoid overheating of the engine, the components around the combustion chamber (cylinder liner, cylinder head, valves, etc.) must be properly cooled. In order to ensure the cooling effect, the car cooling system is generally composed of radiators, thermostats, water pumps, cylinder body water channels, cylinder head water channels, fans, etc. The air intake grille of the car is located at the front of the car. It is the window for heat exchange between the parts around the combustion chamber of the car and the outside world. In addition to decorating the appearance of the car, it also plays a role in controlling the heat balance of the car. [0003] In most cases, the intake grille needs to have a large area of ​​contact with the outside world, because the engine generates a lot of...

AI Technical Summary

Problems solved by technology

In the variable air duct device that controls the outside air flowing into the radiator, there is a variable louver that is installed between the grille opening of the vehicle and the radiator, extends in the vehicle width direction, and faces the outside of the radiator The introduction amount of air is adjusted; and the link mechanism makes the variable louver and the lower louver co-operate in unison, and applies an external force to the lower louver to block the linkage between the variable louver and the lower louver, allowing the lower louver to swing, but, The variable air duct device cannot close all the shutters to meet the driving needs in severe cold areas, and the device is relatively complicated and takes up a large amount of valuable space in the engine compartment
