Further, when a first element is described as being coupled or coupled to a second element, the description includes embodiments in which the first and second elements are directly coupled or coupled to each other, as well as embodiments in which one or more additional intervening elements are added to indirectly couple or couple the first and second elements to each other.

It should be noted that fig. 1-17 are exemplary only, are not drawn to scale, and should not be construed as limiting the scope of the invention as actually claimed.

The front end module of the vehicle also comprises an active air inlet grille, and the active air inlet grille can change the opening and closing of the air inlet grille to control air inflow and wind resistance, so that the fuel economy is improved, and the better working temperature of the engine is quickly reached.

The active air inlet grille comprises a main frame, a driving mechanism and a blade group. The main frame is provided with an air inlet, wherein the blade group comprises one or more blades, the blades are rotatably arranged at the air inlet, the driving mechanism is used for driving the blades to rotate so as to open or close the air inlet, and the blades are also used for guiding the airflow passing through the air inlet. The intake grill assembly according to the embodiment of the present invention may be, but is not limited to, an active intake grill.

As shown in fig. 1 and 2, in one embodiment of the present invention, the air intake grill assembly 900 includes a main frame 1, a blade 3, and a flow guide 2, the main frame 1 having an aperture 1a for allowing the air flow F to pass therethrough; the flow guide part 2 is connected to the main frame 1 and is used for guiding the air flow F; the vane 3 is rotatably disposed in the aperture 1 a. The flow guide 2 serves to guide the air flow F towards the main frame 1 so that the air flow F can pass through said main frame 1 via the aperture 1 a. The flow guide 2 also serves to guide the air flow F through the orifice 1a in a direction away from the main frame 1.

In the embodiment of the present invention, the flow direction of the air flow F is from front to back.

As shown in fig. 3, the number of the air guides 2 is plural, wherein at least two air guides 2 are respectively connected to the front and rear sides of the main frame 1, wherein the air guides 2 connected to the front side of the main frame 1 have a shape of a circumferentially closed wall body, and the air guides 2 connected to the rear side of the main frame 1 have a shape of a plate. The flow guide in the shape of a circumferentially closed wall defines the flow path of the air flow F.

With continued reference to fig. 3, the main frame 1 has a first body 10 and a first edge structure 11, the first body 10 having an aperture 1a for allowing the air flow F to pass through; the first edge structure 11 and the first body 10 are arranged in front and back in the flow direction of the air flow F; the blade 3 is attached to the first body 10 and is located in the aperture 1 a. In this embodiment, the first edge structure 11 may be located in front of the first body 10 or in back of the first body 10 in the flow direction of the air flow F.

In a more specific embodiment, as shown in fig. 3, the number of the first edge structures 11 is plural, at least one of the plural first edge structures 11 is located at the front side of the first body 10, and at least another one of the plural first edge structures 11 is located at the rear side of the first body 10. Accordingly, at least one of the plurality of flow guides 2 is disposed at a front side of the first edge structure 11 located at a front side of the first body 10, and at least one of the plurality of flow guides 2 is disposed at a rear side of the first edge structure 11 located at a rear side of the first body 10 in a flow direction of the air flow F.

With continued reference to fig. 3, the baffle 2 has a second body 20 and a second edge formation 21; the second edge structure 21 and the second body 20 are arranged one behind the other in the direction of flow of the air flow F; in this embodiment, the second edge structure 21 may be located in front of the second body 20 or behind the second body 20 in the flow direction of the air flow F.

When the second edge structure 21 is located in front of the second body 20, the second body 20 functions to direct the airflow F away from the main frame 1. When the second edge structure 21 is located behind the second body 20, the second body 20 functions to direct the air flow F towards the main frame 1.

As shown in fig. 4, 5, 6, 7, 8, 9, in order to reduce leakage of the air flow F from between the main frame 1 and the flow guide 2, one of the first edge structure 11 and the second edge structure 21 has a groove G into which the other of the first edge structure 11 and the second edge structure 21 is arranged to protrude.

Since one of the first edge structure 11 and the second edge structure 21 has a groove G, the other of the first edge structure 11 and the second edge structure 21 is configured to protrude into the groove G, which enables the first edge structure 11 or the second edge structure 21 protruding into the groove G to be limited by the groove G, and after the air flow F enters the groove G from one side of the first edge structure 11 or the second edge structure 21, at least one 180 ° turn needs to be performed to enable the air flow F to flow out of the groove G from the other side of the first edge structure 11 or the second edge structure 21, which is equivalent to providing an obstruction to the leakage of the air flow F, thereby reducing the leakage of the air flow F.

In a particular embodiment, the second edge structure 21 has the recess G into which the first edge structure 11 is arranged to protrude. This arrangement helps to further reduce leakage of the air flow F between the main frame 1 and the deflector 2 on the upstream side of the orifice 1 a. This is because, with this arrangement, the flow direction of the air flow F on the upstream side of the orifice 1a toward the orifice 1a is opposite to the flow direction of the air flow F flowing into the groove G, so that the air flow F is made less likely to flow toward the groove G, thereby reducing the possibility of leakage of the air flow F.

In a preferred embodiment, the first edge structure 11 may be arranged in connection with the second edge structure 21, thereby enabling the attachment of the baffle 2 to the main frame 1. In other embodiments, the air guiding element 2 may not be directly in contact with the main frame 1, but may be connected to a third party to remain relatively still, for example, the first body 10 and the second body 20 are connected to the framework of the front end module of the vehicle.

In the embodiment in which the first edge structure 11 is connected to the second edge structure 21, said first edge structure 11 comprises a first edge body 11a and a first connection portion 11 b; the second edge structure 21 has the groove G; said first edge body 11a is arranged to project into said groove G; the first connection portion 11b connects the second edge structure 21. This design makes the first edge structure 11 compact.

With continued reference to fig. 4 and 9, the second edge structure 21 has a connecting wall 210, a first wall 211 and a second wall 212; the connecting wall 210 is connected to the second body 20, and the first wall 211 and the second wall 212 are respectively connected to the connecting wall 210; wherein the connecting wall 210, the first wall 211 and the second wall 212 together define the groove G; the first connection portion 11b is connected to the first wall 211 and/or the second wall 212 and/or the connection wall 210. This design gives the second edge structure 21 a high structural strength. In the embodiment shown in fig. 4, the first wall 211 is adapted to be connected to the first connection portion 11 b; in the embodiment shown in fig. 9, the first connection portion 11b is connected to the connection wall 210. In an embodiment not shown, the first connection portion 11b is connected to the second wall 212.

In a more specific embodiment, the first connecting portion 11b is clamped with the first wall 211 and/or the second wall 212 and/or the connecting wall 210. Correspondingly, the first wall 211 and/or the second wall 212 and/or the connecting wall 210 are provided with through holes 2a for clamping with the first connecting parts 11 b. In the embodiment shown in fig. 4, the first wall 211 has a through hole 2a, and in the embodiment shown in fig. 9, the connecting wall 210 has a through hole 2 a.

Fig. 10, 11, 12, 13 show a flow guide 2 in the form of a plate. As shown in fig. 3, in the intake grill assembly 900, the number of the plate-shaped flow guide members 2 is two, and both are located behind the first body 10 and are connected to both sides of the main frame 1, respectively.

With continued reference to fig. 13, the second edge structure 21 of the baffle 2 also has ribs 213; the rib 213 is arranged in the groove G and defines with the first wall 211 and/or the second wall 212 a gap 2b allowing the first edge body 11a to be inserted. This solution helps to limit the first edge body 11 a.

As can be seen in fig. 3, 6, 7, 8, 9, 14, 15, 16, 17, the first edge structure 11 extends in a circumferential direction of the aperture 1a with a tendency to surround the aperture 1 a. The first edge structure 11 may be circumferentially closed, but in the embodiment shown in fig. 3 the first edge structure 11 is designed to be discontinuous for avoiding the blade driving mechanism, and correspondingly the second edge structure 21 with the groove G is also discontinuous. In an embodiment not shown, the first edge structure 11 may be circumferentially closed, and the groove G may also be annular.

With continued reference to fig. 15, 16 and 17, the number of the first edge structures 11 and the flow guide 2 is respectively plural; in the flow direction of the air flow F, at least one of the first edge structures 11 is located on the front side of the first body 10, and at least another one of the first edge structures 11 is located on the rear side of the first body 10; in the flowing direction of the air flow F, at least one of the plurality of flow guides 2 is disposed at the front side of the first edge structure 11 located at the front side of the first body 10, and at least one of the plurality of flow guides 2 is disposed at the rear side of the first edge structure 11 located at the rear side of the first body 10.

In addition, in embodiments not shown in the drawings, the first edge structure 11 or said second edge structure 21 may have a plurality of grooves G. For example, the number of the grooves G of the second edge structure 21 is plural, and correspondingly, the number of the first edge bodies 11a inserted into the grooves G is also plural. The plurality of first edge bodies 11a protrude into the plurality of grooves G, respectively. For two adjacent grooves G, the air flow F will turn at least 180 ° after flowing out of one of the grooves G to enter the other groove G adjacent to it, and therefore, the air flow F needs to go through several 180 ° turns after entering one of the grooves G from one side of the first edge structure 11 or the second edge structure 21, before it can be leaked. The technical scheme further increases the difficulty of leakage of the airflow F and improves the sealing property.

Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the present invention, and those skilled in the art can make modifications and variations without departing from the spirit and scope of the present invention.
