Description

Technical Field

[0001] The utility model relates to the technical field of air intake grilles, in particular to an automobile air intake grille with the functions of reducing resistance and saving energy. Background Art

[0002] The air intake grille, also known as the front face of the car, radiator cap, etc., mainly functions to provide air intake and ventilation for the water tank, engine, air conditioner, etc., to prevent foreign objects from damaging the internal components of the car during driving, and to decorate the front face of the car.

[0003] In the prior art, automobile air intake grilles are usually located at the front face of the vehicle. When driving on a muddy road with water on the road surface, relatively moist mud will often splash. This mud can easily adhere to the air intake grille when the vehicle is driving at a low speed. Once this moist mud solidifies, it is difficult to remove it. This mud will not only affect the air intake effect of the automobile air intake grille, disrupt the intake airflow, and cause the engine cooling effect to decrease, but will also greatly affect the aesthetics of the car. In view of this, we propose an automobile air intake grille with reduced resistance and energy saving. Utility Model Content

An adjusting cylinder 9 is connected, and two ventilation slots 10 extending into the interior are provided on the outer surface of the adjusting cylinder 9, and the two ventilation slots 10 are arranged in a mirror-image staggered manner. A knob 11 is rotatably connected to the lower surface of the frame 1, and an adjusting cavity 12 is provided inside the frame 1. An adjusting component is provided inside the adjusting cavity 12. The grille bars 4 are placed in a horizontal state through the adjusting component, and then the grille bars 4 can be cleaned more conveniently and quickly with the help of compressed air and in conjunction with half of the air outlet holes 8 being opened. The two ventilation slots 10 arranged in a mirror-image staggered manner can avoid the problem of reduced air flow rate due to the large number of air outlet holes 8.

[0026] Furthermore, the adjustment component includes an electric push rod 13, which is fixedly connected to the top wall of the adjustment chamber 12, and a limit rod 14 is fixedly connected between the upper and lower inner walls of the adjustment chamber 12. A tooth plate 15 is provided inside the adjustment chamber 12, and a connecting plate 16 is fixedly connected to the rear surface of the tooth plate 15. The lower end of the electric push rod 13 is fixedly connected to the connecting plate 16, and the rear surface of the tooth plate 15 is fixedly connected to a limit sleeve 17. The limit sleeve 17 is slidably sleeved on the outer surface of the limit rod 14. The outer surface of the adjustment shaft 3 located inside the adjustment chamber 12 is sleeved with a gear 18, and the gear 18 is meshed with the tooth plate 15. The lower surface of the frame 1 is opened. A through slot 19 is provided which extends into the interior of the ventilation cavity 5. A connecting shaft 20 is fixedly connected to the upper surface of the knob 11.

[0027] Working principle: When it is necessary to clean the solidified mud spots on the surface of the grille bar 4, first, the electric push rod 13 cooperates with the connecting plate 16 to push the tooth plate 15 downward. When the tooth plate 15 moves, it will synchronously cooperate with the gear 18 to drive the adjustment shaft 3 to rotate. When the adjustment shaft 3 rotates, it will synchronously drive the grille bar 4 to rotate. After the grille bar 4 rotates, it is in a horizontal state. At this time, by connecting the external compressed air to the air inlet 6, the compressed air then enters the interior of the ventilation chamber 5 through the air inlet 6, and enters from the interior of the ventilation chamber 5 through the air outlet 8. The air is blown from the inside of the air intake slot 2 to the surface of the grille bar 4, and the mud spots on the surface of the grille bar 4 are removed by means of high-speed air flow. After the upper part of the grille bar 4 is cleaned, by turning the knob 11, the knob 11 synchronously drives the adjustment cylinder 9 to rotate with the help of the connecting shaft 20. After the adjustment cylinder 9 is rotated, the two ventilation slots 10 are rotated ninety degrees, and then the upper air outlet 8 is closed and the lower air outlet 8 is opened, thereby cleaning the lower air intake grille bar 4, and the electric push rod 13 is used to adjust the opening and closing range of the grille bar 4 according to the vehicle speed.
