Remaining space.
Preferably, described in two groups in air inlet 1, wherein one group enclose around each air inlet 1 sets one
Sealing plate 5 is enclosed,
It is enclosed jointly equipped with a circle sealing plate 5 another group of outer ring in two air inlets 1；
The sealing plate 5 is respectively positioned on the air inlet direction side of the type variable active air-inlet grille frame 2, is used for and automobile
Existing air-inlet grille connection sealed around.
One circle sealing plate 5 of setting is in order to guarantee leakproofness, to make the air come in from air-inlet grille completely by additional
Formula can be changed the control of active air-inlet grille, so that reinforcing addition type can be changed the effect that active air-inlet grille plays.
Preferably, a circle stiffening ring 6 is cased in the outside of every circle sealing plate 5.
Stiffening ring 6 is to prevent air pressure from the sealing of sealing plate 5 and air-inlet grille being caused to connect to preferably fetter sealing plate 5
Connect gas leakage.
Preferably, the stiffening ring 6 passes through 7 clamping of buckle with the type variable active air-inlet grille frame 2.
The mode of buckle 7 connects, and easy to use, fixation is easy to process.
As shown in Fig. 1 to Fig. 6, in the optinal plan of the present embodiment, it is arranged on the type variable active air-inlet grille frame 2
There are multiple mounting legs 8, is reserved with bolt hole on each mounting leg 8.
Setting mounting leg 8 is that the variable active air-inlet grille of addition type is mounted in automobile for convenience, to keep it solid
It is fixed secured.
Automobile embodiment
This embodiment offers a kind of automobile, the automobile includes fixed air-inlet grille, further includes as described above attached
Formula is added to can be changed active air-inlet grille, the variable active air-inlet grille of the addition type is installed on the airintake direction of the air-inlet grille
