DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Please refer to Figures 1-4 , the present utility model provides the following technical solutions:

[0019] Specifically, it refers to a wear-resistant light-transmitting grille, including a frame 1. A number of grille bars 2 are fixedly installed in the frame 1. The number of grille bars 2 is set according to the actual length of the frame 1, which will not be elaborated here. A rear slot 3 is opened on the back of the grille bar 2. At the same time, the rear slot 3 is arranged on the leeward side of the light-transmitting grille panel. A rotating shaft 4 is rotatably connected between the inner walls on the upper and lower sides of the rear slot 3. A rotating block 5 is fixedly sleeved on the rotating shaft 4. The other side of the rotating block 5 extends out of the rear slot 3 and is fixedly connected with a shielding plate 6. When the shielding plate 6 rotates to a 90-degree angle with the grille bar 2, the shielding plate 6 will block the space between the grille bar 2 and the inner wall of the frame 1 and the space between the grille bars 2, so as to achieve the effect of sealing most areas of the light-transmitting grille, reducing the situation that small animals enter the engine compartment through the gaps of the grille when the vehicle is placed outdoors, and further ensuring the safety of the engine compartment during operation.

[0020] In this embodiment, the front surface of the grille bar 2 is in the shape of an isosceles trapezoid, and a wear-resistant layer is additionally provided, which can increase the wear resistance of the surface of the grille bar 2 and reduce the situation that the surface of the grille bar is scratched when the light-transmitting grille is in use.

[0021] In this embodiment, the side of the shielding plate 6 away from the rotating block 5 is hemispherical, which can avoid the problem of jamming between the shielding plate 6 and the inner wall of the frame 1 or the grille bar 2 during the rotation process.

[0022] In this embodiment, there is a distance of 0.3-0.5 mm between the upper and lower sides of the baffle 6 and the inner wall of the frame 1. In this way, while blocking most small animals from entering the engine compartment, it can also ensure the intake air volume of the engine compartment when the vehicle is running, so that the vehicle can run normally.

[0023] Specifically, a control cavity 7 is opened in the frame 1. The upper end of the rotating shaft 4 rotatably penetrates into the control cavity 7. A gear 8 is fixedly sleeved on the outer surface of the end of the rotating shaft 4 located in the control cavity 7. A transverse sliding rod 11 is fixedly connected between the opposite inner walls of the control cavity 7. A transverse sliding sleeve 10 is slidably sleeved on the transverse sliding rod 11. A rack 9 is fixedly connected to the side of the transverse sliding sleeve 10 close to the gear 8. The rack 9 is meshed with the gear 8. A tension spring 12 is fixedly connected between the transverse sliding sleeve 10 and the inner wall of the control cavity 7. The tension spring 12 is movably sleeved on the outer surface of the transverse sliding rod 11. When the tension spring 12 is not affected by the pulling force, the tension spring 12 will form a pulling force on the transverse sliding sleeve 10, so that the initial position of the transverse sliding sleeve 10 is close to the left side, so as to control the initial position of the shielding plate 6 to seal the grille;

[0024] When the vehicle is in motion, the airflow will exert a thrust on the baffle 6, causing the baffle 6 to rotate inward and driving the rotating shaft 4 to rotate clockwise. At the same time, the gear 8 rotates synchronously. In this way, the gear 8 meshes and drives the rack 9 to displace to the right. At the same time, the rack 9 exerts a tensile force on the tension spring 12, causing the tension spring 12 to stretch. Since the airflow will continuously push the baffle 6 during the vehicle's motion, the tension spring 12 is always in a stretched state. When the vehicle stops, the baffle 6 loses the thrust of the airflow, so the tension spring 12 pulls the rack 9 to displace to the initial position. At this time, the baffle 6 can block the grille again. With the above structure, no manual control is required, and the light-transmitting grille can be automatically blocked when the vehicle is parked.

[0025] In this embodiment, the front surface of the baffle 6 is set as a concave surface, which increases the windward area of the baffle 6 and further improves the thrust of the airflow on the baffle 6 during the vehicle's motion.

[0026] Specifically, a temperature sensor 13 is provided in the control cavity 7. The detection head of the temperature sensor 13 penetrates through the rear surface of the frame body 1, so that the detection head of the temperature sensor 13 can extend into the engine compartment and detect the temperature in the engine compartment. The bottom wall of the control cavity 7 is fixedly connected with an electric push rod 14. The telescopic end of the electric push rod 14 contacts the rack 9, and the electric push rod 14 is electrically connected to the temperature sensor 13;

[0027] Since the temperature in the engine compartment is relatively high when the vehicle stops running or idles, the temperature sensor 13 can transmit a signal to the electric push rod 14. The electric push rod 14 is activated and exerts a thrust on the rack 9, causing the rack 9 to drive the gear 8 to rotate clockwise, so that the baffle 6 no longer blocks the grille, thus ensuring the heat dissipation of the engine compartment.

[0028] The working principle of the wear-resistant light-transmitting grille provided by the present utility model is as follows: When the vehicle is in motion, the airflow will exert a thrust on the baffle 6, causing the baffle 6 to rotate inward and driving the rotating shaft 4 to rotate clockwise. At the same time, the gear 8 rotates synchronously. In this way, the gear 8 meshes and drives the rack 9 to displace to the right. At the same time, the rack 9 exerts a tensile force on the tension spring 12, causing the tension spring 12 to stretch. Since the airflow will continuously push the baffle 6 during the vehicle's motion, the tension spring 12 is always in a stretched state. When the vehicle stops, the baffle 6 loses the thrust of the airflow, so the tension spring 12 pulls the rack 9 to displace to the initial position. At this time, the baffle 6 can block the grille again.
