The grille body 2 is of an inverted trapezoid structure with wide upper part and narrow lower part, 7 mounting holes are formed along the upper bottom edge, 5 mounting holes are formed in the lower bottom surface, 3 mounting holes are respectively formed in two waists, and the variable air inlet grille 1 with the gradually opened and closed external type is arranged on a vehicle. The grid body 2 is provided with 112 triangular ventilation openings in total, and the 112 ventilation openings form 8 rows and are arranged in a staggered and mutually meshed mode up and down to cover the whole surface of the grid body 2.
Three groups of air exchanging mechanisms are sequentially arranged on the back surface of the grid body 2, namely the surface where the view angle direction is located in fig. 1 from left to right. Wherein, the left and right groups of air exchanging mechanisms comprise an executing motor 31, a synchronous connecting rod, 5 rotating shafts, 35 blade connecting rods 35, 35 blades 36, 35 blade covers 37 and 5 shaft covers 38. The middle set of ventilation mechanism includes an actuator motor 31, an output link 32, a synchronizing link, 5 shafts, 42 blade links 35, 42 blades 36, and 42 blade covers 37, sharing a shaft cover 38.
In the ventilation mechanism on the left side, 5 rotating shafts are sequentially parallel from top to bottom and are arranged at the position near the left side on the back surface of the grid body 2 at equal intervals. The left end of the 5 rotating shafts is inserted into a large preset inserting hole on the grid body 2, the right end of the 5 rotating shafts is clamped into a large preset clamping groove on the grid body 2, and then a shaft gland 38 is arranged at the large clamping groove to limit the grid body.
The uppermost and the lower two rotating shafts are positioned close to the upper edge and the lower edge of the grille body 2, and the middle three rotating shafts are positioned between the ventilation openings of the adjacent rows. The lower part of the first rotating shaft is provided with 5 hinge points from top to bottom, and the positions of the hinge points correspond to 5 ventilation openings on the left side of the first row respectively; the upper and lower parts of the second rotating shaft are respectively provided with 5 hinge points, and 5 ventilation openings respectively correspond to the upper and lower parts of the second rotating shaft; similarly, please refer to the accompanying drawings, which will not be described again.
Within each vent is a triangular vane 36 that covers the vent. The vane 36 is parallel to the shaft and extends near one side of the shaft at both ends to form an axis. The device is installed in a similar manner to the rotating shaft, namely, the left end is inserted into a small jack preset on the grid body 2, the right end is clamped into a small clamping groove preset on the grid body 2, and then a blade gland 37 is arranged at the small clamping groove to limit the grid body.
Hinge points are also arranged at the positions of the back surfaces of the blades 36 far away from the tip ends of the rotating shafts, and are in one-to-one correspondence with one ends of the blade connecting rods 35. The other ends of the blade connecting rods 35 are movably connected with hinge points arranged on the rotating shaft in a one-to-one correspondence manner.

And a hinge point is additionally arranged at the position close to the synchronous connecting rod on each rotating shaft and is used for being movably connected with the synchronous connecting rod. The synchronous connecting rod is parallel to the waist on the left side of the grille body 2.
When the motor 31 is started, the power output shaft rotates forward or backward to drive the uppermost rotating shaft to rotate, so as to drive the synchronous connecting rod to swing up and down. The synchronous connecting rod swings and drives the other four rotating shafts to synchronously rotate. Finally, the blade 36 is driven to swing back and forth by the blade connecting rod 35, so that the opening and closing of the blade 36 are realized.

Blade link 35, blade 36 、 The arrangement of the vane gland 37, the shaft gland 38 and the synchronizing link is substantially identical to that of the left ventilation mechanism, and will not be described again.
The actuating motor 31 is provided at the middle of the upper bottom edge of the grill body 2, and is not conveniently and directly connected with the rotation shaft, so that the output link 32 is added. The power output shaft of the execution motor 31 faces horizontally to the right and is movably connected with one end of the output connecting rod 32, and the other end of the output connecting rod 32 is movably connected with the upper end of the synchronous connecting rod.
When the motor 31 is started, the power output shaft rotates forward or backward to drive the synchronous connecting rod to swing up and down. The synchronous connecting rod swings and drives the other five rotating shafts to synchronously rotate. Finally, the blade 36 is driven to swing back and forth by the blade connecting rod 35, so that the opening and closing of the blade 36 are realized.
In addition, for the convenience of clear display and description of the structure of the rotating shafts, five rotating shafts in the left ventilation mechanism are marked as 341-345 from top to bottom in sequence; five rotating shafts in the middle ventilation mechanism are sequentially marked as 346-3410 from top to bottom; five rotating shafts in the right ventilation mechanism are marked as 3411-3415 from top to bottom.
