Description

Technical Field

[0001] The utility model relates to the technical field of intake grilles, and particularly relates to an intake port protection device for an AGS active intake grille. Background Art

[0002] The active intake grille (AGS) mainly actively controls the intake angle of the intake grille through a motor, affecting parameters such as air fluidity and intake air volume. By using the active intake grille (louvered blades) to control the airflow passing through the grille to cool the cooling system and the engine compartment, it can not only optimize the aerodynamic performance of the vehicle, but also when the vehicle starts in a cold state, the intake grille active closing system can control the blades to remain closed for a long time, enabling the engine to reach the appropriate operating temperature faster, thereby helping the vehicle reduce fuel consumption.

[0003] When some existing AGS active intake grilles are in use, they usually use a motor to adjust the active intake grille. However, when the vehicle is traveling at high speed and the intake grille is closed, due to the vehicle traveling at high speed, the wind will impact the intake grille, which will cause the intake grille to be blown by the external wind force, and it is easy to cause the intake grille to bend. During long-term driving, it is easy to cause deformation of the intake grille. Summary of the Utility Model

Specific embodiments

[0023] This part will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the drawings. The function of the drawings is to supplement the description of the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it should not be construed as a limitation on the protection scope of the present utility model.

[0024] Please refer to Figures 1-5 , the present utility model provides a technical solution: an intake port protection device for an AGS active intake grille, including an air grille frame 1, a rotating shaft 3 is rotatably connected inside the air grille frame 1, grille blades 2 are fixedly installed on the surface of the rotating shaft 3, a drive motor 4 is fixedly installed on one side of the air grille frame 1, the output end of the drive motor 4 rotates through the air grille frame 1 and extends to the inside of the air grille frame 1, a drive shaft 11 is fixedly installed at the output end of the drive motor 4, a winding disc 5 is fixedly installed at the end of the drive shaft 11 away from the drive motor 4, a slideway 8 is opened inside the air grille frame 1, a blocking rod 7 is slidably connected inside the slideway 8, a positioning rod 9 is fixedly installed inside the slideway 8, the surface of the positioning rod 9 is slidably connected with the inside of the blocking rod 7, a return spring 10 is movably sleeved on the surface of the positioning rod 9, both ends of the return spring 10 are fixedly connected with the blocking rod 7 and the inner wall of the slideway 8 respectively, a connecting rope 6 is fixedly installed between the blocking rod 7 and the winding disc 5, the connecting rope 6 is slidably connected inside the air grille frame 1, and the shape of the slideway 8 is U-shaped.

[0025] When protecting the grille blade 2, start the drive motor 4 to drive the drive shaft 11 to rotate, thereby driving the winding disc 5 to rotate. Then, the two grooves on the winding disc 5 wind the two connecting ropes 6 around the winding disc 5 respectively, pulling the two blocking rods 7 to move relatively, so that the two blocking rods 7 slide inside the two slideways 8 and on the surfaces of the two positioning rods 9 respectively, squeezing the two return springs 10, and preventing the blocking rods 7 from blocking the central position of the grille blade 2. When the drive motor 4 rotates in the reverse direction, the two blocking rods 7 are reset by the elastic force of the two return springs 10, and the blocking rods 7 block the grille blade 2, preventing the grille blade 2 from being impacted when the vehicle is driving at high speed, preventing the grille blade 2 from bending, improving the protection of the grille blade 2, extending the service life of the grille blade 2, and preventing the grille blade 2 from deforming.

[0026] Since the slideway 8 is U-shaped, when the two slideways 8 move continuously, the two blocking rods 7 will enter the two transverse grooves of the two slideways 8, hiding the blocking rods 7 inside the slideways 8 and preventing the blocking rods 7 from affecting the rotation of the grille blade 2.

[0027] A disc 12 is fixedly installed on the surface of the drive shaft 11. A drive slideway 13 is formed on the surface of the disc 12. The drive slideway 13 is in the shape of an 'e'. A sliding push rod 14 is slidably connected inside the drive slideway 13. A moving frame 15 is fixedly installed on the sliding push rod 14. A toothed plate 20 is fixedly installed on the surface of the moving frame 15. A gear 19 is fixedly installed at one end of the rotating shaft 3 extending into the air grille frame 1. The gear 19 meshes with the toothed plate 20. A polygonal rod 16 is fixedly installed inside the air grille frame 1. A moving block 18 is slidably connected to the surface of the polygonal rod 16. One end of the moving block 18 close to the moving frame 15 is fixedly connected to the moving frame 15. A elastic spring 17 is movably sleeved on the surface of the polygonal rod 16. One end of the elastic spring 17 close to the moving block 18 is fixedly connected to the moving block 18. The other end of the elastic spring 17 away from the moving block 18 is fixedly connected to the polygonal rod 16.

[0028] When the drive shaft 11 rotates, it will cause the sliding push rod 14 to slide inside the drive slideway 13. Then, when the two blocking rods 7 enter the transverse grooves of the two slideways 8, the sliding push rod 14 will enter the inclined groove of the drive slideway 13. Then, the inclined groove of the drive slideway 13 will pull the sliding push rod 14 to move, and at the same time, the two blocking rods 7 will continue to move into the two slideways 8. When the sliding push rod 14 moves, it drives the moving frame 15 and the toothed plate 20 to move. At the same time, the two moving blocks 18 slide on the surfaces of the two polygonal rods 16, squeezing the elastic spring 17. Then, when the toothed plate 20 moves, it drives the gear 19 and the rotating shaft 3 to rotate, and then the grille blades 2 are flipped. Then, when the moving frame 15 moves the maximum distance, the rotating shaft 3 and the gear 19 are flipped by ninety degrees, and then the air grille frame 1 is opened, which is convenient for controlling the grille blades 2, thus facilitating active air intake and improving the control of the air intake volume of the device.

[0029] Through the setting of the polygonal rod 16, it is convenient to limit the moving block 18 and the moving frame 15, and then the moving frame 15 moves horizontally, preventing the moving frame 15 from disengaging from the toothed plate 20, ensuring the safety of the device during use.

[0030] Working principle:

[0031] Start the drive motor 4, so that the drive motor 4 drives the drive shaft 11 to rotate. Then, the winding disc 5 rotates, and the two grooves on the winding disc 5 wind the two connecting ropes 6 around the winding disc 5 respectively, and then pull the two blocking rods 7 to move relatively. The two blocking rods 7 slide inside the two slideways 8 and on the surfaces of the two positioning rods 9 respectively, and then squeeze the two return springs 10. Then, the blocking rods 7 no longer block the central position of the grille blades 2. When the drive motor 4 rotates in the reverse direction, the two blocking rods 7 are reset by the elastic force of the two return springs 10, and then the blocking rods 7 block the grille blades 2.

[0032] When the drive shaft 11 rotates, it will cause the sliding push rod 14 to slide inside the drive slideway 13. Then, when the two blocking rods 7 enter the inner part of the cross grooves of the two slideways 8, the sliding push rod 14 will enter the inner part of the inclined groove of the drive slideway 13. Then, the inclined groove of the drive slideway 13 will pull the sliding push rod 14 to move, and at the same time, the two blocking rods 7 will continue to move into the two slideways 8. When the sliding push rod 14 moves, it drives the moving frame 15 and the toothed plate 20 to move. At the same time, the two moving blocks 18 slide on the surfaces of the two polygonal rods 16, squeezing the elastic spring 17. Then, when the toothed plate 20 moves, it drives the gear 19 and the rotating shaft 3 to rotate, and then the grille blades 2 are flipped. Then, when the moving frame 15 moves the maximum distance, the rotating shaft 3 and the gear 19 are flipped by ninety degrees, and then the air grille frame 1 is opened, facilitating the control of the grille blades 2.

[0033] The above has described the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present invention.
