When the driving motor 2 is started, if the air inlet 40 needs to be reduced from the maximum opening, the driving motor 2 drives the connecting rod assembly 3 to move, and the connecting rod assembly 3 drives the grille blades 1 to move from the open position 11 to the closed position 12 or other intermediate positions; if the air inlet 40 needs to be fully closed and the air inlet 40 is enlarged, the driving motor 2 controls the connecting rod assembly 3 to drive the grille blades 1 to move from the closed position 12 to the open position 11 or other intermediate positions, so that the air inlet area adjustment of the grille blades 1 relative to the air inlet 40 can be satisfied.

In this embodiment, the grille blade 1 is driven by the link assembly 3 to perform translational motion all the time, so that the grille blade 1 presents the same spatial posture in the state that the air inlet 40 on the front bumper body 4 is completely opened, partially opened or completely closed, and when foreign matters enter, the grille blade can push away the foreign matters by means of the moving force, or even if the foreign matters enter and cannot push away, the driving motor is stopped, the damage to the grille blade is not caused, and the risk of jamming caused by the foreign matters to the grille blade 1 is reduced. As shown in fig. 12, when the user looks toward the active grille from the front end of the automobile, the line of the grille vane 1 at the air inlet 40 is always an outer contour line of the grille vane 1, so that the visual aesthetic feeling of the modeling can be maintained.

In this embodiment, the link assembly 3 may have various manifestations according to practical needs, for example, a worm gear structure, and may convert the rotation of the driving motor into the movement of the grille vane 1, or similar to a manipulator with multiple degrees of freedom, to translate the grille vane 1 between two extreme positions.

In view of practical situations such as actual space arrangement of the bumper assembly and manufacturing process cost, as a preferred embodiment of the present utility model, as shown in fig. 5 to 9, the link assembly 3 includes:

If the driving motor 2 is started, the driving motor 2 drives the first connecting rod 31 to rotate, the first connecting rod 31 drives the grille blade 1 to move, the grille blade 1 drives the second connecting rod 32 to rotate, the hinge point at the other end of the second connecting rod 32 is set at a fixed position, the four hinge points are at the four vertex angles of the parallelogram, and finally the first connecting rod 31 and the second connecting rod 32 synchronously rotate, so that the grille blade 1 can move in space, but the movement posture is fixed, and further the position of the grille blade changes in a translational mode in space.

As shown in fig. 5 to 9, the link further includes:

When foreign matters hit the grille vane 1, a certain disturbance may occur to the grille vane 1, and in order to enhance the stability and reliability of the grille vane 1, at least one third link 33 is disposed at an end opposite to the first link 31 or the second link 32, so that the grille vane 1 has three support points, wherein the third link 33 and the links may have substantially the same specification and size, and all the third links 33 and links rotate together.

In a specific embodiment, as shown in fig. 9, the number of third links 33 is two, and two third links 33 are disposed on the same end of the grille blade 1.

Further, the free ends of the links are hinged on a frame body 5, the frame body 5 being configured to fit the front bumper body 4 arrangement.

In this embodiment, the first link 31 is used as a driving rod, the second link 32 and the third link 33 are driven rods, one ends of the first link 31, the second link 32 and the third link 33 are all hinged at four corners of the grille vane 1, the other end of the first link 31 is connected with the output end of the driving motor 2, the other ends of the second link 32 and the third link 33 are respectively hinged on the frame 5, the specific structure of the frame 5 is set according to actual requirements, the effective lengths of the links are the same, and the driving motor 2 is also mounted on the frame 5. When the driving motor 2 drives the first link 31 to rotate, the second link 32 and the third link 33 both rotate around the same direction, so as to drive the grille blades 1 to perform translational movement in space.

As a preferred embodiment of the present utility model, the grille blades 1 are of one-piece construction. The one-piece type blade changes the traditional upper and lower layered form of the blade, so that the line of the active grille on the front end of the vehicle, which is provided by the utility model, is not damaged, and the processing and the production are convenient.

Further, the number of the louver blades 1 is the same as that of the intake ports 40. One intake port 40 corresponds to one grille vane 1.

As shown in fig. 6 to 12, in a specific embodiment, if the number of the air inlets 40 is two, two grille blades 1 are distributed on both sides of the driving motor 2.

In general, the front bumper assembly of the automobile has two air inlets 40 distributed left and right, a driving motor 2 is installed at a middle and upper portion of the two air inlets 40, the driving motor 2 is installed at an indoor side of the front bumper body 4, that is, when the grille blades 1 are at the open position 11, the grille blades 1 are also completely hidden at the indoor side of the front bumper body 4, the two grille blades 1 are distributed at two sides of the driving motor 2, and the driving motor 2 drives the left and right two first links 31 to synchronously rotate downwards so that the two grille blades 1 can cover the two air inlets 40. The driving motor 2 is arranged in the center of the two air inlets 40, so that the left and right grille blades 1 share one driving motor 2, the cost is saved, the driving motor 2 drives the left and right first connecting rods 31 to rotate, the second connecting rods 32 and the third connecting rods 33 of the left and right grille blades 1 rotate around the respective hinged ends under the driving of the first connecting rods 31, a movement envelope shown in fig. 2 is formed, the left and right grille blades 1 are driven to translate by a four-connecting rod mechanism, and the X-direction space requirement of the vehicle during movement of the left and right grille blades 1 is reduced a lot compared with that of the rotation of the one-piece grille blades, so that the problem that the X-direction space of a front cabin of the vehicle is limited is solved very well, wherein the X-direction refers to the running direction of the vehicle.

When the air inlet 40 is completely opened and completely closed, if grille blades are present in the bumper opening area at the front end of the vehicle, the outer contour of the blades is always seen by the user at the front end of the vehicle, so that the integrity and the appearance of the model are well maintained. In the whole movement process state of the grille blades 1, the visual effect of the front end of the vehicle is just that the contour line of the grille blades is arranged in the opening area of the bumper, and the front face modeling line is not damaged at all.

Regarding the grid blades according to the traditional rotation motion, when foreign matters enter the driving grid, the foreign matters are easy to be blocked, and the driving grid needs to increase torque to start an ice breaking mode, so that on one hand, the service life of the motor can be influenced by the increase torque of the driving motor, and on the other hand, the grid blades can be cracked due to high force when the ice is broken by increasing torque. The grid blades in the active grid of the embodiment move in a moving mode, when foreign matters enter, the foreign matters can be pushed away by means of moving force, or even if the foreign matters enter and cannot be pushed away, the driving motor can be stopped, and obvious damage to the grid blades can be avoided.

In this embodiment, if the grille vane 1 is just matched with the air inlet 40, the driving motor 2 continues to drive the first connecting rod 31 to rotate, so that the grille vane 1 may be pushed out further, and the grille vane 1 is prevented from moving further outwards after reaching the closed position 12 by the limit part 13 at the edge of the grille vane 1. The limiting portion 13 may be formed by extending and bending the grille blade 1 outwards, and preferably, the limiting portion 13 and the grille blade 1 may be an integral member formed by direct stamping.

Preferably, the grille blade 1 is hinged with the link assembly 3 by a blade bracket 14, and the grille blade 1 is fixedly mounted on the blade bracket 14.
