Abstract
Description
Technical Field
[0001] This disclosure relates to the field of automotive air intake technology, and more specifically, to an asymmetric air intake assembly. Background Technology
[0002] In the current automotive market, the air intake of a car consists of a motor and blades. The motor controls two or more blades to open and close. However, currently, the opening method of the blades is consistent, and the opening angle is the same. This design is relatively common. However, automotive styling designs are now more diverse and technologically advanced. Especially when the two blades are of different sizes and shapes, that is, when the two blades are not symmetrical, the traditional blade opening and closing structure design will affect the air intake. Utility Model Content
[0003] Therefore, this utility model provides an asymmetric air intake assembly to solve the problem of air intake in existing asymmetric blade opening and closing systems.
[0004] An asymmetric air intake assembly includes a frame on which a drive motor is mounted, and an air inlet is provided within the frame. The air inlet is provided with a first blade and a second blade of different widths. The drive motor has an output shaft, and a first transmission structure is provided between the first blade and the output shaft, and a second transmission structure is provided between the second blade and the output shaft. When the output shaft rotates, the first blade and the second blade rotate in opposite directions.
[0005] Specifically, both the first blade and the second blade are hinged inside the air inlet, and both the first blade and the second blade have gaps with the inner wall of the air inlet.
[0006] Specifically, the width of the first blade is smaller than that of the second blade.
[0007] Specifically, the first transmission structure includes a first drive rod and a first connecting rod hinged to the first drive rod. The first blade is also provided with a first protrusion plate, and the first connecting rod is hinged to the first protrusion plate.
[0008] Specifically, the second transmission structure includes a second driving rod and a second connecting rod hinged to the second driving rod. The second blade is also provided with a second convex plate, and the second connecting rod is hinged to the second convex plate.
[0009] Specifically, both the first and second drive rods are welded to the output shaft.
[0010] Specifically, there is an air inlet gap between the first blade and the second blade, and a baffle is provided on the second blade to block the air inlet gap.
[0011] Specifically, the first blade is located in a first planar region, and the second blade is located in a second planar region, with the first planar region and the second planar region forming an obtuse angle.
[0012] Specifically, the first blade is hinged in the middle of the first planar region, and the second blade is hinged in the middle of the second planar region.
[0013] Specifically, the first link is longer than the second link, and the first link is bent between the first planar region and the second planar region.
[0014] The technical solution disclosed herein has the following advantages:
[0015] 1. This solution connects two blades to the same output shaft via corresponding linkage mechanisms, that is, it uses a drive motor to drive two blades to rotate simultaneously. The motion path of the four-bar linkage is designed so that the two blades exhibit different rotation angles.
[0016] 2. A baffle is provided on the second blade. When the first and second blades are closed, it blocks the air intake gap between the first and second blades, which can reduce the air intake rate during the car's movement and effectively reduce wind resistance. Attached Figure Description

[0027] This utility model discloses an asymmetric air intake assembly, referring to... Figure 1 , Figure 2 and Figure 3 The system includes a frame 1, on which a drive motor 11 is mounted. An air inlet 12 is provided within the frame 1, and a first blade 13 and a second blade 14 are disposed within the air inlet 12. A first transmission structure 2 connects the drive motor 11 to the first blade 13, and a second transmission structure 3 connects the drive motor 11 to the second blade 14. The widths of the first blade 13 and the second blade 14 are different. The same drive motor 11 simultaneously drives both the first blade 13 and the second blade 14, but with different driving strokes, enabling the first blade 13 and the second blade 14 to rotate in opposite directions.
[0028] Reference Figure 1 and Figure 2 The frame 1 is roughly square, with the front of the frame 1 being the front of the car. The air inlet 12 is located in the middle of the frame 1 and is square. The first blade 13 and the second blade 14 are both rectangular and are arranged side by side inside the air inlet 12. The first blade 13 and the second blade 14 are of equal length, and the width of the first blade 13 is smaller than the width of the second blade 14. The drive motor 11, the first transmission structure 2, and the second transmission structure 3 are installed on the back of the frame 1. The drive motor 11 can be fixed by bolts.
[0029] The drive motor 11 has an output shaft 111 located on one side of the air inlet 12 in the width direction. The first transmission structure 2 includes a first drive rod 21 and a first connecting rod 22. The first blade 13 has a first protruding plate 131. The first drive rod 21, the first connecting rod 22, and the first protruding plate 131 constitute a hinged four-bar linkage. During transmission, the output shaft 111 rotates, driving the first drive rod 21 to rotate. The first connecting rod 22 performs a translational motion, driving the first protruding plate 131 to move, thereby driving the first blade 13 to rotate. By designing the length ratio of the first connecting rod 22, the first drive rod 21, and the first protruding plate 131, the motion path of the first blade 13 can be designed. In this scheme, the first drive rod 21 can be welded to the output shaft 111, and the first protruding plate 131 and the first blade 13 can be integrally formed. The rods are connected by short shafts to form a hinge.
[0030] The second transmission structure 3 includes a second driving rod 31 and a second connecting rod 32. The second blade 14 has a second convex plate 141. The second driving rod 31, the second connecting rod 32, and the second convex plate 141 constitute a hinged four-bar linkage. The transmission method of the second transmission structure 3 is the same as that of the first transmission structure 2, and will not be described again here. The second convex plate 141 is also integrally formed with the second blade 14. The second driving rod 31 is welded to the output shaft 111, that is, the first driving rod 21 and the second driving rod 31 are both fixedly connected to the same output shaft 111. Therefore, when the output shaft 111 rotates, the first blade 13 and the second blade 14 can be linked. By designing the length of each rod, the stroke of the first blade 13 and the second blade 14 can be adjusted to achieve the first blade 13 and the second blade 14 rotating at opposite angles.
[0031] Combination Figure 3 The first blade 13 is located in the first planar region 15, and the second blade 14 is located in the second planar region 16. The first planar region 15 and the second planar region 16 are set at an obtuse angle. Both the first blade 13 and the second blade 14 have gaps with the air inlet 12. A first hinge seat 17 is provided on each side of the inner wall of the air inlet 12 along its length. The first blade 13 is hinged to the first hinge seat 17 via a short shaft. The first hinge seat 17 is located in the middle of the width direction of the first planar region 15. A second hinge seat 18 is provided on each side of the inner wall of the air inlet 12 along its length. The second blade 14 is hinged to the second hinge seat 18 via a short shaft. The second hinge seat 18 is located in the middle of the width direction of the second planar region 16. The length of the first connecting rod 22 is greater than that of the second connecting rod 32. The first connecting rod 22 is bent between the first planar region 15 and the second planar region 16 to prevent interference between the first connecting rod 22 and the frame 1.
[0032] There is an air intake gap 19 between the first blade 13 and the second blade 14. A baffle 142 is provided on the second blade 14. The baffle 142 is elongated and is formed in one piece with the second blade 14 in this design. When the first blade 13 and the second blade 14 are closed, the baffle 142 blocks the air intake gap 19 to reduce the amount of air entering the vehicle during driving and reduce wind resistance.
[0033] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom remain within the scope of this disclosure.
