Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, in particular to an active air intake grille blade, an air intake grille assembly and a vehicle. BACKGROUND

[0002] With the improvement of environmental protection requirements and the development of the automobile industry, the requirements for vehicle energy saving and emission reduction are also becoming higher and higher. Active air intake grille can change the opening and closing of the air intake grille to control the air intake and wind resistance, thereby improving fuel economy and quickly reaching the optimal working temperature of the engine, so the application of active air intake grille is becoming more and more popular. Active air intake grille is generally divided into built-in type and external type. The external type active air intake grille can not only meet the performance of traditional active air intake grille, but also increase the three-dimensional sense of the vehicle and meet the aesthetic sense of the appearance design of the times, so the external type active air intake grille is applied more and more.

[0003] The current external type active air intake grille, such as the patent with publication number CN116834542A, discloses an active air intake grille, which includes a frame, a blade, a connecting rod and a driving member. The blade is horizontally rotatably arranged on the frame and is distributed in the vertical direction of the frame. The same end of the blade is fixed with a rotating shaft, the axis of the rotating shaft is parallel to the rotating axis of the blade, the connecting rod is arranged on the frame along the distribution direction of the blade, the rotating shaft is rotatably connected to the connecting rod, and the driving member drives the connecting rod to open or close the blade. The scheme fixes the rotating shaft at the end of the blade, rotatably connects the rotating shaft to the connecting rod, and only needs to drive the connecting rod to move by the driving member when opening or closing is needed, so that the connecting rod can drive multiple blades to rotate to open or close.

[0004] Although the above-mentioned active air intake grille can drive multiple blades to rotate to open or close, the current active air intake grille still has the following problems: in order to ensure the rigidity of the blade, the transverse size of the blade cannot be too large, resulting in that the size of the active air intake grille is relatively small. If the transverse size is enlarged according to the above-mentioned scheme, the rigidity of the blade will be soft, and the blade is prone to deformation. In addition, the front surface of the conventional external active air intake grille is a plane, and the back surface is arranged with reinforcing ribs. The active air intake grille is a large plane when the blades are closed, and the reinforcing structure at the back is exposed when the blades are opened, which affects the modeling aesthetics of the vehicle.

[0053] Embodiment 1,

[0054] The present embodiment proposes an active air intake grille blade, as shown in Figures 1-2 including a blade outer plate 11 and a blade inner plate 12, the blade outer plate 11 and the blade inner plate 12 are fixed by buckling, both sides of the blade outer plate 11 in the length direction are integrally formed with outer plate flanges 111 of about 7mm bent to the same side, and the longitudinal section is in the shape of "["; both sides of the blade inner plate 12 in the length direction are integrally formed with inner plate flanges 121 of slightly less than 7mm bent to the same side, i.e. the longitudinal section is in the shape of "]", and a cavity is formed between the blade outer plate 11 and the blade inner plate 12; when assembling, the blade outer plate 11 in the shape of "[" is buckled on the blade inner plate 12 in the shape of "]", and the section forms a "[]" type cavity.

[0055] In this embodiment, the width of the blade inner plate 12 is slightly smaller than the width of the blade outer plate 11; in order to ensure the rigidity of the entire blade 1, the blade inner plate 12 in this embodiment is also made of high-strength fiber-reinforced material; as shown in Figure 2 In order to prevent the blade outer plate 11 and the blade inner plate 12 from falling off during assembly, the edge of the outer plate flange 111 is provided with a reverse buckle 112, and the outer side flange 129 of about 1.2mm is provided on the inner plate flange 121, and the reverse buckle 112 is connected to the outer side flange 129 of the blade inner plate 12. As shown in Figure 3 and Figure 4As shown, in order to fix the blade outer plate 11 and the blade inner plate 12, the blade outer plate 11 is integrally formed with a welding column 113 on the side close to the blade inner plate 12, the blade inner plate 12 is provided with a welding hole 123 matching the welding column 113, and the welding column 113 is fixedly installed in the welding hole 123. The blade outer plate 11 and the blade inner plate 12 are fixedly connected through the cooperation of the welding column 113 and the welding hole 123, and the connection is stable.

[0056] In order to further increase the rigidity of the blade 1, the embodiment is provided with Figure 3 and Figure 4 As shown, the blade inner plate 12 is provided with a first reinforcing rib 122 on the side close to the blade outer plate 11, and the height of the first reinforcing rib 122 is equal to the height of the inner plate flange 121.

[0072] Active air intake grille blade 1 rotation process: motor 3, drive connecting rod 4, drive connection plate 5 in initial position, blade 1 in closed state, as Figure 15 . The motor 3 rotates to drive the drive connecting rod 4 to rotate downward, and the U-shaped groove 41 structure of the drive connecting rod 4 drives the drive connection plate 5 to move downward. The drive connection plate 5 moves downward to drive the drive shaft of each blade 1 to move, and the position of the rotating shaft 125 of the blade 1 is fixed and can only rotate, and the second drive shaft 126 can only rotate around the rotating shaft. The motor 3 rotates to the lower limit block 57 position, the drive connecting rod 4 side surface contacts the lower limit surface of the middle part of the active air intake grille body 2, the blade 1 drive connection plate 5 drives the blade 1 to rotate 90 degrees, to the blade 1 open position. Active air intake grille blade 1 fully open, as Figure 16 .

[0073] Example 3,

[0074] The embodiment is a vehicle, comprising a vehicle body, wherein the vehicle body is provided with the active air intake grille blade of the embodiment 1. The active air intake grille blade of the vehicle can be made longer than the traditional blade under the same rigidity, thereby meeting the requirement of manufacturing large-size active air intake grille; and the reinforcing rib can be arranged on the blade inner plate on the cavity side, thereby further improving the rigidity of the blade, avoiding arranging the reinforcing rib on the outer wall of the blade inner plate, and designing the back of the blade as a smooth plane, so that the blade back is free of redundant design and visual when the blade is in the open state. When the plurality of blades are combined and the active air intake grille is closed, the shielding flange can shield the gap between the adjacent two blades, thereby making the closure of the entire active air intake grille better and more beautiful.
