[0017] The following further detailed description of the present application is made in conjunction with the accompanying drawings, and it is necessary to point out here that the following detailed description is only used to further illustrate the present application, and cannot be understood as limiting the protection scope of the present application, and the skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0018] EMBODIMENT

[0019] like Figure 1 - Figure 4 As shown, a fast heat dissipation grille assembly includes a mounting frame 1, a connecting frame 6 fixedly connected to the rear end periphery of the mounting frame 1, and a fixing hole 7 for fixing the mounting frame 1 to the vehicle frame is formed on the side wall of the connecting frame 6. The user can pass external bolts through the fixing holes 7 formed in the connecting frame 6 and then screw them to the vehicle frame to achieve the fixation of the entire heat dissipation grille assembly;

[0020] A crossbeam 2 is horizontally installed in the inner cavity at the front end of the installation frame 1. A plurality of grille plates 3 are arranged perpendicular to the installation frame 1 behind the crossbeam 2. A connecting groove 4 is opened on the side of the grille plate 3 close to the crossbeam 2. The grille plate 3 is sleeved on the crossbeam 2 through the connecting groove 4. A gap is left between the inner wall of the connecting groove 4 and the outer surface of the crossbeam 2. While preventing the grille plate 3 from being interfered with by the crossbeam 2 when rotating, it also prevents the inner wall of the connecting groove 4 from rubbing against the crossbeam 2, which causes wear on the grille plate 3 and the crossbeam 2.

[0021] The plurality of grille plates 3 are evenly spaced, and an air intake channel is formed between two adjacent grille plates 3. When the vehicle is driving, air can enter the vehicle through the air intake channel between the grille plates 3 to dissipate heat from the engine.

[0022] Both ends of the grille plate 3 are fixedly connected to a rotating shaft 5, and the end of the rotating shaft 5 away from the grille plate 3 is rotatably connected to the inner wall of the mounting frame 1, so that the multiple grille plates 3 can rotate around the rotating shaft 5 to adjust the angle of the air intake channel, facilitate direct blowing to different positions of the engine, and improve the heat dissipation efficiency of the automobile engine;

[0023] Two fixing blocks 8 are symmetrically installed on both sides of the rear end of the mounting frame 1. A screw rod 9 is rotatably connected between the two fixing blocks 8. Bearings are installed at the connection between both ends of the screw rod 9 and the fixing blocks 8. The inner ring of the bearing is sleeved on the end of the screw rod 9 and fixed to the screw rod 9. The outer ring of the bearing is embedded in the fixing block 8 and fixed to the fixing block 8, which can greatly reduce the friction resistance of the screw rod 9 when it rotates.

[0024] A servo motor 10 for driving the screw rod 9 to rotate is fixedly installed on the outside of one of the fixed blocks 8. Multiple grille plates 3 are rotatably connected to an inner screw ring 14 on one side close to the screw rod 9 through a connecting piece. The connecting piece includes two ear plates 11 fixedly installed on the side of the grille plate 3 close to the screw rod 9. A telescopic rod 12 is arranged between the two ear plates 11. A pin 13 is fixedly passed through one end of the telescopic rod 12. Both ends of the pin 13 respectively pass through the two ear plates 11 and are rotatably connected to the ear plates 11. The other end of the telescopic rod 12 is fixed to the outer wall of the inner screw ring 14. The inner screw ring 14 is sleeved on the screw rod 9 and screwed to the screw rod 9. When the servo motor 10 starts to drive the screw rod 9 to rotate, the inner screw ring 14 can be pushed to move along the length direction of the screw rod 9 through the thread on the screw rod 9, thereby driving the grille plate 3 to rotate around the rotating shaft 5 through the telescopic length of the telescopic rod 12 itself in conjunction with the ear plate 11 and the pin 13, thereby realizing the adjustment of the angle of the air intake channel.

[0025] It should be noted that, when this kind of fast heat dissipation grille assembly is used, the mounting frame 1 is installed on the front end of the automobile frame through the fixing hole 7 opened on the connecting frame 6. When the car is driving, the air can enter the front cabin of the car through the air intake channel formed between the adjacent grille plates 3 in the mounting frame 1 to dissipate heat from the automobile engine. At the same time, the user can start the servo motor 10, and the servo motor 10 drives the screw rod 9 to repeatedly rotate forward and reverse. During the rotation of the screw rod 9, the thread on the screw rod 9 pushes the inner screw ring 14 to move along the length direction of the screw rod 9, so that the grille plate 3 is driven to rotate around the rotating shaft 5 through the telescopic length of the telescopic rod 12 itself. The ear plate 11 and the pin shaft 13 drive the grille plate 3 to rotate around the rotating shaft 5 to adjust the air intake angle of the air intake channel. When the air intake angle of the air intake channel is adjusted to a certain angle with the front of the engine, the air can be blown directly to the outside of the engine through the air intake channel, which greatly improves the heat dissipation efficiency of the automobile engine and avoids the problem that the existing automobile air intake grille is fixed on the front side of the frame, and the air entering the front cabin of the car cannot be blown directly to both sides of the engine, thereby reducing the heat dissipation efficiency of the engine.

[0026] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
