[0002] The car grille is a crucial component connecting the hood, front bumper, and left and right headlights, its primary function being ventilation and heat dissipation. The coolant tank and air conditioning condenser are both cooling elements located behind the grille, allowing for better heat dissipation through the air entering the grille. Furthermore, the grille also protects the internal structure of the car body, preventing damage to core components from external objects during driving.

[0003] When a car is in motion, due to the high speed, many insects and other debris can easily get stuck in the gaps of the grille, making it difficult for users to clean and affecting the car's appearance. Utility Model Content

[0004] The purpose of this utility model is to provide an automotive grille to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A car grille includes a fixed frame, a first rectangular opening is provided in the middle of the surface of the fixed frame, an inner frame is installed in the first rectangular opening, a second rectangular opening is provided in the middle of the surface of the inner frame, a plurality of equally spaced blades are provided in the second rectangular opening along its length direction, and the middle of the upper and lower ends of each blade are rotatably connected to the upper and lower inner walls of the second rectangular opening through a rotating shaft, and a mounting groove is provided in the top cavity of the inner frame, and a driving structure for driving the multiple rotating shafts to rotate simultaneously is provided in the mounting groove.

[0006] Preferably, the upper and lower sides of the fixed frame are provided with a plurality of straight plate fasteners distributed at equal intervals along its length, and the middle part of the left and right ends of the fixed frame is provided with L-shaped fasteners.

[0007] Preferably, the inner wall of the first rectangular opening is provided with an inner edge, the back of the inner frame is in contact with the surface of the inner edge, and the inner frame and the inner edge are fixedly connected by screws.

[0008] Preferably, the drive structure includes a connecting shaft, which is rotatably connected to the mounting groove via a bearing. The top end of each rotating shaft extends into the mounting groove and is fitted with a second bevel gear. Each second bevel gear is rotatably connected to a first bevel gear. The first bevel gear and the second bevel gear mesh with each other, and the first bevel gear is fitted onto the connecting shaft.

[0009] Preferably, the top side of the inner frame is provided with notches corresponding to the mounting groove, and one end of the connecting shaft extends into the notch and is provided with a knob.

[0010] Preferably, the inner frame has a threaded hole located below the notch on its surface, and a locking bolt is threaded into the threaded hole, with the nut of the locking bolt contacting the surface of the knob.

[0011] The automotive grille of this utility model has the following advantages:

[0012] 1. This utility model, by rotating the connecting shaft, causes multiple first bevel gears on the connecting shaft to rotate simultaneously, thereby causing each first bevel gear to drive the second bevel gear connected to it to rotate, which in turn causes the blade connected to it to rotate, thus achieving adjustment of the blade tilt angle. At the same time, when many small insects or other debris stick to the blades due to the car moving forward, rotating the connecting shaft can rotate each blade to a flat state, making it easier to clean the small insects and debris stuck to each blade, greatly improving convenience.

[0013] 2. By using threaded holes and locking bolts, this utility model allows the locking bolt nut to be tightly contacted with the knob surface when the blade angle is adjusted. This increases the friction between the locking bolt nut and the knob, thereby locking and fixing the knob. This effectively prevents the blade from rotating randomly due to loose knob, ensuring the stability of the structure. Attached Figure Description

[0027] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an automotive grille according to this utility model.

[0028] like Figure 1-6 As shown, this utility model discloses a car grille, including a fixed frame 1. Multiple equally spaced straight fixing members 2 are provided on the back of the upper and lower sides of the fixed frame 1 along its length. L-shaped fixing members 3 are provided in the middle of the inner parts of the left and right ends of the fixed frame 1. The fixed frame 1 can be fixedly installed on the vehicle body via the straight fixing members 2 and the L-shaped fixing members 3. A first rectangular opening 6 is provided in the middle of the surface of the fixed frame 1. An inner frame 4 is installed inside the first rectangular opening 6. An inner edge 7 is provided on the inner wall of the first rectangular opening 6. The back of the inner frame 4 contacts the surface of the inner edge 7, and the inner frame 4 and the inner edge 7 are fixedly connected by screws. The inner edge 7 serves to block and limit the movement of the inner frame 4, and the screw connection between the inner frame 4 and the inner edge 7 facilitates the assembly and disassembly of the inner frame 4 from the fixed frame 1.

[0029] A second rectangular opening 8 is provided in the middle of the surface of the inner frame 4. Multiple equally spaced blades 5 are arranged within the second rectangular opening 8 along its length. The middle of the upper and lower ends of each blade 5 are rotatably connected to the upper and lower inner walls of the second rectangular opening 8 via a rotating shaft 14. A mounting groove is provided in the top cavity of the inner frame 4. A drive structure for driving multiple rotating shafts 14 to rotate simultaneously is provided in the mounting groove. The drive structure includes a connecting shaft 13, which is rotatably connected to the mounting groove via a bearing. The top end of each rotating shaft 14 extends into the mounting groove and is fitted with a second bevel gear 16. Each second bevel gear 16 is rotatably connected to a first bevel gear 15. The first bevel gear 15 and the second bevel gear 16 are rotatably connected to the first bevel gear 16. Two bevel gears 16 mesh with each other, and a first bevel gear 15 is sleeved on a connecting shaft 13. By rotating the connecting shaft 13, multiple first bevel gears 15 on the connecting shaft 13 rotate simultaneously, thereby causing each first bevel gear 15 to drive the second bevel gear 16 connected to it to rotate. This causes the second bevel gear 16 to drive the blade 5 connected to it to rotate, thereby adjusting the tilt angle of the blade 5. At the same time, when many small insects or other debris stick to the blade 5 due to the car moving forward, the connecting shaft 13 can be rotated to make each blade 5 flat, making it easy to clean the small insects and debris stuck to each blade 5, greatly improving convenience.

[0030] The top side of the inner frame 4 has notches 9 corresponding to the mounting groove. One end of the connecting shaft 13 extends into the notch 9 and has a knob 10. The notch 9 and knob 10 allow the operator to easily rotate the connecting shaft 13 by hand. Below the notch 9, the surface of the inner frame 4 has a threaded hole 11. A locking bolt 12 is threaded into the threaded hole 11. The nut of the locking bolt 12 contacts the surface of the knob 10. Through the threaded hole 11 and locking bolt 12, when the angle of the blade 5 is adjusted, tightening the locking bolt 12 ensures a tight contact between the nut of the locking bolt 12 and the surface of the knob 10, increasing the friction between them and thus locking the knob 10 in place. This effectively prevents the knob 10 from loosening and causing the blade 5 to rotate freely, ensuring structural stability.

[0031] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
