Adjustable car ventilation grille system and car

Abstract

The invention discloses an adjustable automobile air grid system which comprises an air grid (5), a controller (2), a temperature sensor (6), a drive mechanism (3) and an executing mechanism (4), wherein the air grid comprises a grid frame (9) and a plurality of grid vanes (8) arranged on the gid frame and capable of rotating, the temperature sensor (6) is used for sensing temperature of an engine cylinder body and transmitting a signal of the temperature of the engine cylinder body to the controller, and the controller is in electric connection with the drive mechanism (3) and used for controlling and driving the drive mechanism (3) according to the signal of the temperature of the engine cylinder body. The adjustable automobile air grid system is reasonable in design, simple in structure, capable of replacing an automobile air grid in the prior art, meanwhile, capable of overcoming the defects that the automobile air grid in the prior art is fixedly normal open, an automobile is not easy to start under low temperature, abrasion to an engine is big when the automobile runs under the low temperature for a long time, and fuel economy is low, so that the engine is enabled to always work within an appropriate working temperature range, and working performance of the engine is improved obviously.

Description

technical field [0001] The invention relates to an automobile ventilation grille, in particular to an adjustable automobile ventilation grille system. In addition, the invention also relates to a car installed with the adjustable car ventilation grille system. Background technique [0002] The engine generally uses a water cooling system to dissipate heat. The water pump circulates the water in the water jacket of the engine block in the radiator to dissipate heat. Take away the heat from the radiator. However, the engine compartment is a relatively closed space, and in order to supply the cooling air to the cooling fan, a ventilation grill is generally installed on the body panel to allow the cooling air to enter. For example, for a car with a front engine, a ventilation grid is generally installed on the front wall of the body to allow the air to ventilate. [0003] The opening and closing state of the ventilation grille of the motor vehicle in the prior art is a non-ad...

Problems solved by technology

[0005] In addition, the non-adjustable ventilation grille of the prior art will also lead to worse fuel economy of the engine working in a low-temperature environment. Specifically, when the car is running in a low-temperature environment, the engine block temperature is low and the heating time is long. The internal friction is high, the output power decreases, and the fuel consumption increases. If the cold air continuously enters through the ventilation grille, the above situation will be exacerbated.

Generally speaking, when starting at low temperature, the time for the engine to heat up to 40°C-50°C should be shortened as much as possible, but the above-mentioned non-adjustable ventilation grille will obviously prolong the temperature rise time
