Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figures 1-5This utility model provides an embodiment: an integrated, paint-free front bumper grille, including a mounting frame 1, a reinforcing rib 2 on the front side of the mounting frame 1, a grille mesh 3 on the left and right sides of the reinforcing rib 2, a winding chamber 4 at the upper rear end of the mounting frame 1, a winding roller 5 inside the winding chamber 4, a coil spring 501 at both ends of the winding roller 5, a dustproof cloth 6 on the outer side of the winding roller 5, a lifting plate 7 at the lower end of the dustproof cloth 6, a lead screw 8 at the rear side of the mounting frame 1, a motor 9 fixedly mounted at the lower end of the mounting frame 1, a first limit plate 10 on the left and right sides of the lead screw 8, a second limit plate 11 fixedly mounted on the left and right sides of the rear side of the mounting frame 1, a metal protective mesh 12 between the first limit plate 10 and the second limit plate 11, and a drive assembly 13 on the side of the second limit plate 11.
[0025] Please see Figures 1-4 In this embodiment, the left and right ends of the roller 5 are rotatably connected to the mounting frame 1 via a rotating shaft. One end of the coil spring 501 is fixedly connected to the outer side of the rotating shaft, and the other end is fixedly connected to the inner side of the take-up chamber 4. One end of the dustproof cloth 6 is fixedly connected to the roller 5, and the other end of the dustproof cloth 6 extends to the outer side of the take-up chamber 4 through a through groove and is fixedly connected to the lifting plate 7. The dustproof cloth 6 is arranged around the roller 5. The upper and lower ends of the lead screw 8 are rotatably connected to the mounting frame 1. The output end of the motor 9 is drively connected to the lower end of the lead screw 8. The lead screw 8 is threadedly connected to the lifting plate 7. The first limiting plate 10 and the second limiting plate 11 are both fixedly connected to the inner side of the mounting frame 1. The lifting plate... The rear side of the lifting plate 7 slides against the surfaces of the first limiting plate 10 and the second limiting plate 11, and the front side of the lifting plate 7 slides against the inner side of the mounting frame 1. When the vehicle is parked, the motor 9 controls the screw 8 to rotate, causing the lifting plate 7 to slide down along the first limiting plate 10 and the second limiting plate 11, pulling the dustproof cloth 6 to unfold and cover the rear side of the grid 3, thus blocking dust and impurities. The coil spring 501 provides deflection force to the roller 5, so that the dustproof cloth 6 is in a taut state. Subsequently, the screw 8 rotates in the opposite direction to drive the lifting plate 7 to rise, and the coil spring 501 drives the roller 5 to reset, so that the dustproof cloth 6 is rolled up to the outside of the roller 5, thus achieving rapid storage of the dustproof cloth 6.
[0026] Please see Figures 2-5In this embodiment, multiple metal meshes 12 are arranged side by side, one end of which is rotatably connected to a limiting plate 10, and the other end of which is rotatably connected to a limiting plate 11.

The lower end of the linkage rod is provided with an electric push rod for driving the linkage rod to move. The electric push rod is fixedly connected to the inner side of the mounting frame 1. When the vehicle is driving in an environment with a lot of sand and gravel, the electric push rod of the drive assembly 13 controls the linkage rod to drive multiple metal meshes 12 to deflect to a vertical state, thereby blocking the sand and gravel and preventing sand and gravel from entering the engine compartment. When the vehicle returns to a good environment, the multiple metal meshes 12 are controlled to deflect to a horizontal state to increase the ventilation volume.
[0027] When the vehicle is in use, in environments with a lot of sand and gravel, the electric push rod of the drive assembly 13 controls the linkage rod to drive multiple metal guards 12 to deflect to a vertical state, thereby blocking sand and gravel and preventing them from entering the engine compartment. When the vehicle returns to a good environment, the multiple metal guards 12 are controlled to deflect to a horizontal state to increase ventilation. When the vehicle is parked, the motor 9 controls the screw 8 to rotate, causing the lifting plate 7 to slide down along the first limit plate 10 and the second limit plate 11, pulling the dustproof cloth 6 to unfold and cover the back of the grid mesh 3, thereby blocking dust and impurities. The coil spring 501 provides deflection force to the roller 5, keeping the dustproof cloth 6 in a taut state. Subsequently, the screw 8 rotates in the opposite direction to drive the lifting plate 7 to rise, and the coil spring 501 drives the roller 5 to reset, so that the dustproof cloth 6 is rolled up to the outside of the roller 5, achieving rapid storage of the dustproof cloth 6.
[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
