The present invention relates to the field of vehicle equipment, specifically to an active air intake assembly and a motor vehicle with such an active air intake assembly.
Many motor vehicles have mechanisms for air intake, such as air intake grilles, on the front face. Air from the front of the vehicle enters the interior of the vehicle via the air intake grille, for example for the operation of an internal combustion engine or for temperature regulation of various components within the vehicle.
The air intake grille of some motor vehicles is known as an active air intake grille. Vanes that are mounted on the active air intake grille can be actively controlled by the vehicle, so that the positions of the vanes are adjusted according to various requirements, thereby regulating the flow of air through the air intake grille. In another aspect, in general, the appearance of the air intake grille as seen from the outside of the vehicle has an aesthetic effect on the appearance of the front face of the vehicle, as the air intake grille is located on the front face of the vehicle.
Therefore, there is still a desire to have an air intake assembly that has an enhanced air intake regulation capability and can help the vehicle to have a specific front face appearance.
Regarding the above problem, according to a first aspect of the present invention, an active air intake assembly is proposed, comprising: a frame that extends in a longitudinal direction and is provided with an opening for air intake; first and second vanes that extend in the longitudinal direction, the first and the second vanes respectively being rotatably fixed to the frame by a common axis of rotation, and being able to move away from each other from a closed position to an open position to open the opening.
In the active air intake assembly according to the present invention, a simple mechanism enables the first vane and the second vane to move away from each other to an open position, and air flowing through the opening of the active air intake assembly is not obstructed by the vanes at the overall middle of the opening, thereby significantly increasing an amount of air that can flow through the opening at a lower cost, so as to enhance the air intake regulation capability; at the same time, by having the first and second vanes open the opening by dividing into halves, the active air intake assembly has a specific appearance different from that of existing air intake grilles.

Returning to
At the same time, according to the embodiments of the present invention, the rotary shafts 150 all have the same axis of rotation 250. Thus, the first vane 210 and the second vane 220 are respectively rotatably fixed to the frame 100 with a common axis of rotation 250. Moreover, as shown in
The drive apparatus 400 is mounted on one of the vertical plates 110 as shown in
Furthermore, the first drive arm 410 is rotatably connected to one of the multiple first rotating arms 212 and a first rotating arm 212 adjacent thereto, and the second drive arm 420 is rotatably connected to one of the multiple second rotating arms 222 and a second rotating arm 222 adjacent thereto. Specifically, the first drive arm 410 is connected between a first end 2121 that is near the first vane 210 of this first rotating arm 212 and the rotary shaft 150, and the second drive arm 420 is connected between a first end 2221 that is near the second vane 220 of this second rotating arm 222 and the rotary shaft 150. Thus, the first rotating arm 212, the first drive arm 410, the second drive arm 420 and the second rotating arm 222 together form a mechanism of four connecting rods, and the first rotating arm 212 and the second rotating arm 222 form a scissor structure. Thus, the linear motion of the common pivot 442 is transformed into a change in the included angle between the first rotating arm 212 and the second rotating arm 222. As shown in
According to another embodiment of the present invention, a first rotating arm 212 may be arranged at both ends of each first vane section 215, and a second rotating arm 222 may be arranged at both ends of each second vane section 225. The first rotating arms 212 located at both ends of the first vane 210 and the second rotating arms 222 located at both ends of the second vane 220 are rotatably fixed to the frame 100. In addition, the drive apparatus 400 may also be arranged at end parts of the first vane 210 and the second vane 220, for example on a side plate at this end part on the frame 100. In addition, according to another embodiment of the present invention, the first vane 210 may comprise more than three or less than three first vane sections 215 arranged in the longitudinal direction L, and these first vane sections 215 are fixedly connected to each other. Correspondingly, the second vane 220 may comprise more than three or less than three second vane sections 225 arranged in the longitudinal direction L, and these second vane sections 225 are fixedly connected to each other
First, the active air intake assembly 1 of the second embodiment also comprises a frame 100, a first vane 210 and a second vane 220. The frame 100 has an opening 120 extending in the longitudinal direction L for air intake. The opening 120 is defined by a first side edge 121 and a second side edge 122 that extend in the longitudinal direction L, and the frame 100 is further provided with a vertical beam 115 that extends from the first side edge 121 to the second side edge 122, thereby defining two opening sections. In the second embodiment, the frame 100, the first vane 210 and the second vane 220 all extend linearly.
The first vane 210 comprises two first vane sections 215 arranged in the longitudinal direction L, first rotating arms 212 are respectively fixedly mounted at two ends of each first vane section 215, and each first rotating arm 212 can also be rotatably mounted to a rotary shaft 150 of the frame 100, for example on the rotary shaft 150 on a side plate at a vane end part of a vertical plate 110 or the frame 100. The second vane 220 comprises two second vane sections 225 arranged in the longitudinal direction L, second rotating arms 222 are respectively fixedly mounted at two ends of each second vane section 225, and each second rotating arm 222 can also be rotatably mounted to the rotary shaft 150 of the frame 100. The rotary shafts 150 on the frame 100 are all collinear. Thus, the first vane 210 and the second vane 220 are respectively rotatably fixed to the frame 100 by a common axis of rotation 250, and are able to move away from each other from a closed position to an open position to open the opening 120.
In addition, a drive apparatus 400 and an electric motor 460 are both mounted on the vertical plate 110. Similar to the first embodiment, the electric motor 460 is configured to drive the prime mover 430 of the drive apparatus 400 to rotate, and a common pivot 442 is rotatably accommodated in a slide rail of the prime mover 430, so as to be able to slide along the prime mover 430. At the same time, a limiting track 441 on the vertical plate 110 for the common pivot 442 is configured as a linear sliding slot 441 that extends toward the opening 120 and runs through the vertical plate 110. Thus, the common pivot 442, on two sides of the vertical plate 110, respectively, drives a first drive arm 410 and a second drive arm 420 that form a pair.
That is, on either side of the vertical plate 110, one end of each of one first drive arm 410 and one second drive arm 420 are rotatably connected to the common pivot 442 to be driven thereby. Furthermore, in the second embodiment, the first rotating arm 212 has a first end 2121 and a second end 2122 that are located on two sides of the corresponding rotary shaft 150, and the first end 2121 is closer to the first vane 210 compared to the second end 2122, and the second rotating arm 222 has a first end 2221 and a second end 2222 that are located on two sides of the corresponding rotary shaft 150, and the first end 2221 is closer to the second vane 220 compared to the second end 2222. Thus, in the second embodiment, the other end of the first drive arm 410 is rotatably connected to the second end 2122 of the first rotating arm 212 that is remote from the first vane 210, and the other end of the second drive arm 420 is rotatably connected to the second end 2222 of the second rotating arm 222 that is remote from the second vane 220.
Therefore, as shown in
While exemplary implementations of an active air intake assembly and motor vehicle proposed by the present invention have been described in detail above with reference to preferred embodiments, those skilled in the art can understand that various modifications and variations may be made to the specific embodiments without departing from the concept of the present invention, and that various combinations of the technical features and structures proposed by the present invention may be made without exceeding the scope of protection of the present invention.
