Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of intake air deflector devices for automotive throttle valves, and particularly relates to a novel intake air deflector. Background Art
[0002] When the engine throttle is opened, eddy current noise will be generated at the upper and lower edges of the throttle valve flap, causing a throttle whistling problem. For engines on the current market, the throttle is directly installed on the intake manifold, and the throttle whistling problem cannot be improved. Summary of the Invention
[0003] The object of the present invention is to install an intake air deflector between the intake manifold and the throttle valve, which can disrupt the eddy current structure generated downstream of the throttle valve, so as to reduce the whistling sound generated when suddenly stepping on the accelerator and improve the NVH performance. The technical solution is as follows:
[0004] A novel intake air deflector, characterized in that it comprises an intake air deflector main body 1 and ventilation holes 4 provided in the middle of the front surface of the intake air deflector main body 1. A number of guide teeth 3 are evenly distributed and connected to the inner side surface of the ventilation holes 4. A number of mounting holes 5 are provided on the front surface of the intake air deflector main body 1. A sealing rubber ring 2 is connected to the middle of the front surface of the intake air deflector main body 1. The sealing rubber ring 2 is provided at the outer edge of the front surface of the ventilation holes 4. The sealing rubber ring 2 and the ventilation holes 4 are concentric circles. The sealing rubber ring 2 is in a conical shape. The number of mounting holes 5 is provided at the four corners of the front surface of the intake air deflector main body 1. The guide teeth 3 are perpendicular to the inner side surface of the ventilation holes 4.
[0005] The beneficial effect of the present invention is that by installing an intake air deflector between the intake manifold and the throttle valve, the eddy current structure generated downstream of the throttle valve can be disrupted, so as to reduce the whistling sound generated when suddenly stepping on the accelerator and improve the NVH performance.

[0009] Refer to Figure 1 Figure 2The described new type of intake air deflector is characterized in that: it includes an intake air deflector main body 1 and a ventilation hole 4 provided in the middle of the front surface of the intake air deflector main body 1. A number of flow guiding teeth 3 are evenly distributed and connected to the inner side surface of the ventilation hole 4. A number of mounting holes 5 are provided on the front surface of the intake air deflector main body 1. A sealing rubber ring 2 is connected to the middle of the front surface of the intake air deflector main body 1. The sealing rubber ring 2 is arranged at the outer edge of the front surface of the ventilation hole 4. The sealing rubber ring 2 and the ventilation hole 4 are concentric circles. The sealing rubber ring 2 is in a conical shape. A number of the mounting holes 5 are provided at the four corners of the front surface of the intake air deflector main body 1. The flow guiding teeth 3 are perpendicular to the inner side surface of the ventilation hole 4.
[0010] During use, first place the intake air deflector main body 1 between the intake pipe and the throttle valve, and fix the intake air deflector main body 1 by tightening the bolts through the mounting holes 5. The eddy current gas generated by the throttle valve passes through the ventilation hole 4, and at the same time, the eddy current gas is destroyed by the flow guiding teeth 3 to reduce the whistling sound generated when stepping on the accelerator.
[0011] During use, the sealing ring 2 reduces the generation of other noises caused by gas leakage.
[0012] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the essence of the present invention should also fall within the protection scope of the present invention.
