There is material impact to automotive front end air inlet effect, air mass and the distribution in in-car flow field with density degree etc..Air inlet grille
Grid are the important components of automotive front moulding, affect the design style of vehicle, while are also that air flows into car engine
The entrance of cabin.
At present, the air-inlet grille on vehicle is all fixed structure, and active air-inlet grille is by measuring engine water
The information such as temperature, air-conditioning system state, environment temperature, speed, change the blade opening angle of air-inlet grille by control performs device
Degree or the device closed.When the state of air-inlet grille changes, air mass flow and flow direction into enging cabin can
It is affected, causes effective front face area, interior flow field of vehicle cooling system etc. to change, and then vehicle performance is produced
Influence.
Active air-inlet grille has reduction automobile windage coefficient, shortens the engine warms time, reduces oil consumption, reducing and start
Machine cold scuffing, improve the features such as automobile dynamic quality.But active air-inlet grille at present on the market is typically driven using motor
Flowing mode realizes, somewhat expensive and fault rate is higher.
Utility model content
In order to solve problem above present in prior art, the utility model provides a kind of new active air-inlet grille
Control system.
The utility model is achieved through the following technical solutions：
A kind of new active air-inlet grille control system, including aneroid capsule 1, rocker arm body 2, link gear 3, blade
Group 4, supporting mechanism 5, two-way three-way magnetic valve 7 and control unit of engine (ECU) 8；Control unit of engine 8 controls two-way three
Three-way electromagnetic valve 7, realize that aneroid capsule 1 is connected with inlet and outlet manifold so that occur pressure change, vacuum diaphragm in aneroid capsule 1
Push rod in box 1 is pulled or promoted, and the push rod of aneroid capsule 1 is connected to the input on rocker arm body 2, rocker arm body 2
Active blade in output end connection blade group 4, blade group 4 are fixed on supporting mechanism 5, and link gear 3 is by the master of blade group 4
Movable vane piece and passive blade, which link together, realizes that blade links.
Further, it is provided with angular transducer on described rocker arm body 2.
Further, described two-way three-way magnetic valve 7 is connected by connecting line 6 with aneroid capsule 1.
Principle of the present utility model is as follows：Two-way threeway electromagnetism internal path is controlled to change by control unit of engine,
Two-way three-way magnetic valve internal path combination external connection pipeline, realizes that aneroid capsule is connected with inlet manifold (or exhaust manifold)
Connect so that occur negative pressure (or malleation) in aneroid capsule so that empty bellows push rod is in air pressure and the collective effect of spring force
Be moved to a certain position, then by rocker arm body by push rod move caused by translation be converted into the rotation of blade, by this
The purpose for reaching the blade angle change of control blade group is rotated, and blade is fed back by the angular transducer on rocker arm body and rotated
Angle realizes closed-loop control to ECU, the final purpose realized control and enter charge flow rate in enging cabin.
Compared with prior art, it is as follows the advantages of the utility model：
The utility model reaches actively regulation and enters hair by the aperture of air-inlet grille before rationally control in the process of moving
The purpose of motivation cabin cooling air quantity, the interior circulation resistance during traveling is reduced, lift vehicle fuel economy.Actively enter simultaneously
Gas trellis system at low temperatures, by closing grid, to improve the operating temperature of engine as early as possible, in the case of improving winter
Heating effect.
