Technical field

The invention belongs to air-inlet grille for automobile technical fields, and in particular to a kind of active air-inlet grille for automobile.

Background technique

The air-inlet grille of automobile, be usually everybody so-called " big front door ", the effect of air-inlet grille for automobile essentially consists in Air inlet and heat dissipation, air-inlet grille for automobile in the prior art mostly use greatly the air-inlet grille of passive type, if engine radiator When water temperature over-high depends merely on natural air inlet and cannot sufficiently radiate, fan can start auxiliary heat dissipation automatically.It is backward that vehicle, which runs air, Flowing, fan airstream direction is also that backward, the raised air-flow of temperature is from hood rear close to the position of windscreen after heat dissipation Set, there are also (being open below) below vehicle to flow backward, heat just emits.

Active air-inlet grille has more obvious advantage compared to the air-inlet grille of passive type, and active air-inlet grille has The shorter hot vehicle time, and there is lower windage.

Summary of the invention

Technical purpose of the invention is to overcome the problems of the prior art, provides a kind of active air-inlet grille for automobile, real Now the air-inlet grille is capable of the function of automatic shutter air inlet.

To achieve the purpose of the present invention, the technical solution adopted by the present invention are as follows:

A kind of active air-inlet grille for automobile, including inlet duct are provided with several ventholes on inlet duct trailing flank, Inlet duct is divided into left inlet duct and right inlet duct, and left and right inlet duct structure is identical and about in inlet duct Heart vertical axis is symmetrical, and air inlet is provided on inlet duct, and corresponding air inlet hole site is provided with gear inside inlet duct Gas plate, gas block panel are provided with gear I far from air inlet side, and I center of gear extends to form connecting rod I, tooth to gas block panel direction It takes turns I center and extends to form connecting rod II to far from gas block panel direction, be correspondingly connected with inside inlet duct at bar II and be provided with rotation Hole, rotating hole inner circumferential connect connecting rod II, and I upper end of gear has been engaged rack gear, and rack gear on gas block panel one end side far from setting It is equipped with sliding block, corresponding slide position is provided with sliding slot inside inlet duct, and sliding block is slideably positioned in sliding slot, upper end of the rack setting There is a gear II, II position of corresponding gear is provided with decelerating motor inside inlet duct, in geared motor output shaft connection gear II Heart position.

Further, the air inlet hole number on inlet duct is 8-16.

Further, the diameter of gas block panel is greater than the diameter of air inlet.

Further, I central axis of connecting rod is not overlapped with gas block panel central axis.

Beneficial effects of the present invention: a kind of active air-inlet grille for automobile of the present invention, when one section of running car Between when needing air-inlet grille ventilation and heat, decelerating motor band moving gear II rotates, and rack gear is under the drive of gear II in sliding slot Sliding, rack drives gear I move, and gear I drives gas block panel movement, block at this point, air inlet is no longer influenced by gas block panel, air Entering air-inlet grille from air inlet is that automobile realizes ventilation and heat.

The present invention will be further explained below with reference to the attached drawings and specific examples.

Fig. 1 is a kind of front view structural representation of specific embodiment of the present invention.

Fig. 2 is a kind of schematic diagram of internal structure of specific embodiment of the present invention.

Wherein, 1, inlet duct, 2, left inlet duct, 3, right inlet duct, 4, air inlet, 5, gas block panel, 6, gear I, 7, connecting rod I, 8, connecting rod II, 9, rack gear, 10, sliding block, 11, sliding slot, 12, gear II, 13, decelerating motor, 14, rotating hole.

Specific embodiment

Presently in connection with the drawings and specific embodiments, invention is further described in detail.These attached drawings are simplified show It is intended to, the basic structure of the invention will be illustrated schematically only.

As Figure 1-Figure 2, a kind of active air-inlet grille for automobile, main body are inlet duct 1,1 rear side of inlet duct Offer several ventholes on face, inlet duct 1 divides for left inlet duct 2 and right inlet duct 3, for automotive front end air inlet grille The symmetrical beauty of grid, left inlet duct 2,3 structure of right inlet duct are identical and symmetrical about 1 central vertical axis of inlet duct Distribution.

Offer 8-16 air inlets 4 on 1 front end side of inlet duct, when air inlet 4 is opened, air can by into Stomata 4 and venthole are breathing of engine heat dissipation, correspond to 4 position of air inlet inside inlet duct 1 and are equipped with gas block panel 5, keep off gas Plate 5 is equipped with gear I 6 far from 4 side of air inlet, and I 6 center of gear extends to form connecting rod I 7, gear I 6 to 5 direction of gas block panel Center extends to form connecting rod II 8 to far from 5 direction of gas block panel, is correspondingly connected at bar II 8 inside inlet duct 1 and is equipped with rotation Hole 9,9 inner circumferential of rotating hole connect connecting rod II 8.

The engagement of I 6 upper end of gear is equipped with rack gear 9, and rack gear 9 is far from being equipped with sliding block 10, air inlet on 5 one end side of gas block panel 10 position of sliding block is corresponded to inside device 1 and offers sliding slot 11, and sliding block 10 is slidably mounted in sliding slot 11, and 9 upper end of rack gear is equipped with Gear II 12,1 inside corresponding gear of inlet duct, II 12 position are equipped with decelerating motor 13,13 output shaft tooth connection of decelerating motor Take turns II 12 centers.

When running car needs air-inlet grille ventilation and heat for a period of time, decelerating motor 13 is rotated with moving gear II 12, Rack gear 9 slides in sliding slot 11 under the drive of gear II 12, and rack gear 9 is moved with moving gear I 6, and gear I 6 drives gas block panel 5 to transport It is dynamic, it is blocked at this point, air inlet 4 is no longer influenced by gas block panel 5, it is that automobile realizes that ventilation dissipates that air, which enters air-inlet grille from air inlet 4, Heat.

Basic principles and main features of the invention are shown above.Through the above description, relevant staff is complete The variation and modification of multiplicity can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention Property range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
