Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, the conventional active air intake grille 1 has a blade shape that is generally planar, and has no good flow guiding effect. Related studies have shown that in some cases, when the active grille shutter 1 is opened to the maximum position (typically when the vane is rotated to the horizontal position, i.e., the active grille shutter 1 is fully opened), the front intake air amount is not the maximum, but the front intake air amount is the maximum when the vane makes an angle with the horizontal. The main reason is that on the electric automobile, the active air inlet grille 1 is often located at a lower position relative to the front end cooling module 2, so that when the blades deflect for a certain angle, the flow guiding effect is achieved, and the airflow is distributed more uniformly on the surface of the front end cooling module 2. In addition, in many current electric vehicles, the front end cooling module 2 is not vertically disposed, but has a certain inclination angle, please refer to fig. 2 and 3, in this case, a structure is more required to be disposed at the front end to play a role in guiding flow, so that the direction of airflow is more matched with the position of the front end cooling module 2.

However, the airflow is guided by deflecting the angle of the blade, so that the flow area of the airflow is reduced, the resistance of air intake is increased, and the wind resistance of the whole vehicle is increased, and the flow guiding effect is relatively poor, as shown in fig. 4 and 5.

In order to solve the above-mentioned technical problems, referring to fig. 6 to 10, the present embodiment provides an active air intake grille 1 'of an automobile, which is arranged offset from a front-end heat dissipation module, wherein the active air intake grille 1' is disposed downward relative to the front-end heat dissipation module.

In this embodiment, the head of the first half section 111 is provided with a first sealing portion 113, the tail of the second half section 112 is provided with a second sealing portion 114, when the active air intake grille 1' is closed, two adjacent blades 11 are lapped and sealed through the first sealing portion 113 and the second sealing portion 114, so that the tightness between the blades 11 in the closed state is realized, the air leakage of the blades 11 in the closed state is reduced, the wind resistance of the whole automobile is further reduced, and the use effect of the active air intake grille is improved.

In this embodiment, when the active grille shutter 1' is closed, both the first seal 113 and the second seal 114 are disposed leeward.

The specific structural shapes of the first sealing portion 113 and the second sealing portion 114 are not limited in the present utility model, as long as the sealing of the vane 11 in the closed state can be achieved, for example, the first sealing portion 113 and the second sealing portion 114 are respectively in a convex and flat strip-shaped structure, and when the active air intake grille 1' is closed, two adjacent vanes 11 are lapped and sealed on the inner side of the convex through the flat strip-shaped structure.

In this embodiment, the blade 11 is further provided with a plurality of reinforcing ribs 115, where the reinforcing ribs 115 transition from the first half section 111 to the second half section 112, and when the blade 11 is completely opened, the flow directions of the reinforcing ribs 115 and the airflow are the same, that is, the reinforcing ribs 115 can play a role in reinforcing the structure and guiding the air, so that the airflow is distributed uniformly in the length direction of the blade 11 as much as possible.

The two ends of the blades 11 are rotatably arranged in the frame through the rotating shaft 116, the utility model does not limit the arrangement of a plurality of groups of the blades 11 in the frame, the active air inlet grille 1' of the automobile provided by the embodiment comprises a left group of the blades 11 and a right group of the blades 11, the middle part of the frame is divided into a left blade space, a right blade space and a middle driving space through the two partition boards 14, the driving device 13 is arranged between the driving spaces, the left group of the blades 11 and the right group of the blades 11 are respectively positioned between the left blade space and the right blade space, the driving device 13 is in driving connection with the blades 11, and when the driving device 13 works, the blades 11 can be driven to rotate so as to be opened or closed.
