Automatically-regulating new energy vehicle intake grille device

Abstract

The invention provides an automatically-regulating new energy vehicle intake grille device, which comprises an air intake module, a telescopic module and a detection module; the air intake grille device comprises an air intake module, a telescopic module and a detection module. The air inlet module comprises a grille plate and a moving plate; the telescopic module comprises a telescopic rod and asliding cavity; a spring is arranged between the rear end of the sliding rod and the rear side of the sliding cavity; the upper end of the sliding cavity is provided with a positioning groove; the detection module comprises a thermistor, an electromagnet and a limiting piece. The device for automatically adjusting the intake grille of a new energy vehicle is a device for synchronously adjusting the intake size of the intake grille of the vehicle through detecting the temperature of the engine of the vehicle, so that the intake grille of the vehicle increases the intake air quantity with the increase of the temperature of the engine, and plays the roles of heat preservation and heat dissipation.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to an adjustable air intake grille device. Background technique [0002] The function of the air intake grille on the car is to ensure that enough air enters the engine compartment to cool the engine and the radiator tank, and at the same time prevent other debris from entering the engine compartment during driving to protect the engine; but the existing car grille Since the size of the air inlet is fixed, the air intake volume cannot be changed; when the engine is at low temperature and the outdoor temperature is low, the excessively large air inlet of the car grille will cause insufficient heat preservation and excessive heat dissipation of the engine, which may make the engine The normal working temperature can only be ensured by increasing the fuel injection volume to ensure that the gasoline atomization reaches the standard during driving. Obviously, this will increase the fuel consum...

[0002] The function of the air intake grille on the car is to ensure that enough air enters the engine compartment to cool the engine and the radiator tank, and at the same time prevent other sundries from entering the engine compartment during driving to protect the engine; but the existing car grille Since the size of the air inlet is fixed, the air intake volume cannot be changed; when the engine is at low temperature and the outdoor temperature is low, the excessively large air inlet of the car grille will cause insufficient heat preservation and excessive heat dissipation of the engine, which may cause the engine to The normal working temperature can only be ensured by increasing the fuel injection volume to ensure that the gasoline atomization reaches the standard during driving. Obviously, this will increase the fuel consumption of the car; in addition, the car often drives in rainy days. There is a risk of water ingress in the air intake system of the grille, which will lead to a decrease in the filtration performance of the air filter element and the hidden danger of corrosion of the engine injection system; in addition, the existing automobile air intake grille has a large opening , when the car is running at high speed, the position of the car's air intake grille will produce huge wind resistance, which will not only reduce the grip of the car when driving, cause the car to run unstable, but also increase the fuel consumption of the car, which is not conducive to reducing the The cost of use; in summary, there are defects
