[0002] The car air duct is an important part of the vehicle's internal air conditioning and ventilation system. It is responsible for introducing air from outside the vehicle, processing it through the air conditioning system, and then distributing it to every corner of the car to maintain appropriate air quality and temperature inside the car. The car air duct is an indispensable part of the vehicle's internal environmental control system. Its design and maintenance are crucial to providing a comfortable driving and riding experience.

[0003] Traditional automobile air duct structures usually have poor noise reduction effects, which causes external noise of the automobile to be easily transmitted to the interior of the automobile through the automobile air duct structure, thereby affecting the driving experience. In order to make the automobile air duct structure more silent, a silent optimized automobile air duct structure is proposed. Utility Model Content

[0005] In view of this, the utility model provides a silent optimized automobile air duct structure, comprising an air duct body, a first silencer mechanism is arranged at the corner of the inner wall of the air duct body, and a second silencer mechanism is arranged at the air inlet and outlet of the inner wall of the air duct body;

[0006] The first silencer mechanism includes a mounting part, a plurality of first silencers and an air guide part, the mounting part is fixedly mounted at the corner of the inner wall of the air duct body, a first silencer cavity is defined inside the mounting part, the air guide part is fixedly mounted on the inner wall of the first silencer cavity, a plurality of first vents connected to the first silencer cavity are defined on one side of the mounting part, and a plurality of the first silencers are respectively fixedly mounted on the inner wall of the first silencer cavity and the side wall of the air guide part.

[0012] Optionally, the fixing member is trapezoidal.

[0013] It can be seen from the above technical solutions that the embodiments of the utility model have the following advantages:

[0014] 1. The utility model is a silent optimized automobile air duct structure, which adopts a first silencer mechanism. By installing the first silencer on the inner wall of the first silencer cavity and the side wall of the air guide, the sound waves inside the first silencer cavity can be scattered multiple times, and the propagation direction of the sound waves can be changed multiple times inside the first silencer cavity, so that the sound wave energy can be diffused and attenuated.

DETAILED DESCRIPTION

[0023] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0024] A silent optimized automobile air duct structure according to an embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] For easier understanding, see Figures 1 to 4 , an embodiment of a silent optimized automobile air duct structure provided by the utility model comprises an air duct body 1, a first muffler mechanism is arranged at a corner of the inner wall of the air duct body 1, and a second muffler mechanism is arranged at an air inlet and outlet of the inner wall of the air duct body 1;

[0027] The first silencer mechanism includes a mounting member 2, a plurality of first silencers 4 and an air guide member 5. The mounting member 2 is fixedly mounted at the corner of the inner wall of the air duct body 1. A first silencer cavity 3 is provided inside the mounting member 2. The air guide member 5 is fixedly mounted on the inner wall of the first silencer cavity 3. A plurality of first vents 6 connected to the first silencer cavity 3 are provided on one side of the mounting member 2. The plurality of first silencers 4 are respectively fixedly mounted on the inner wall of the first silencer cavity 3 and the side wall of the air guide member 5.

[0028] It should be noted that, by arranging the first vent 6 inside the mounting member 2, the sound waves entering into the air duct body 1 can enter into the first silencer chamber 3 through the first vent 6. By arranging the air guide 5, the airflow inside the mounting member 2 can be guided to pass through the mounting member 2 faster to avoid affecting the circulation of the airflow. By installing the first silencer 4 on the inner wall of the first silencer chamber 3 and the side wall of the air guide 5, the sound waves inside the first silencer chamber 3 can be scattered multiple times, and the propagation direction of the sound waves can be changed multiple times inside the first silencer chamber 3, so that the sound wave energy can be diffused and attenuated, thereby reducing the noise passing through the inside of the air duct body 1 and making the automobile air duct structure more silent.

[0029] In some embodiments, Figure 2 As shown, the air guide member 5 is trapezoidal in shape, and a plurality of first vents 6 are evenly distributed on both sides of the air guide member 5 .

[0030] It should be noted that the air flow can be achieved by setting the air guide member 5 to be trapezoidal in shape.

[0031] In some embodiments, Figure 3 As shown, the second silencer mechanism includes a fixing member 7 and a second silencer 10. The fixing member 7 is fixedly installed at the air inlet and outlet of the inner wall of the air duct body 1. A second silencer cavity 9 is opened inside the fixing member 7. The second silencer 10 is fixedly installed on the inner wall of the second silencer cavity 9. The second silencer 10 is triangular. A plurality of second vents 8 connected to the second silencer cavity 9 are opened on both sides of the fixing member 7. The fixing member 7 is trapezoidal.

[0032] It should be noted that by setting the fixing member 7 to be trapezoidal, the sound waves refracted inside the air duct body 1 can more easily enter the second silencing chamber 9 through the second vent 8. By installing the second silencing member 10 inside the second silencing chamber 9, the sound waves can be reflected multiple times inside the second silencing chamber 9, so that the propagation direction is changed, thereby diffusing and attenuating the energy, thereby reducing the sound waves at the inlet and outlet of the air duct body 1.

[0033] Example 2

[0034] In some embodiments, Figure 4 As shown, the first silencer 4 is hemispherical, and a plurality of annular grooves 11 are formed on the side wall of the first silencer 4 .

[0035] It should be noted that the first silencer 4 and the second silencer 10 are both made of polyurethane foam, so that they have better sound absorption effect. By setting the first silencer 4 to a hemispherical shape and opening a plurality of annular grooves 11 on the side wall of the first silencer 4, the diffusion direction of the sound wave when the sound wave contacts the first silencer 4 can be increased, so that the sound intensity can be decayed faster, and the sound wave contacting the first silencer 4 can be decayed faster, so that the sound silencing effect is better.

[0036] Working principle: By setting a first vent 6 inside the mounting member 2, the sound waves entering the air duct body 1 enter the first silencer chamber 3 through the first vent 6. By setting the air guide 5, the airflow inside the mounting member 2 can be guided to pass through the mounting member 2 faster to avoid affecting the circulation of the airflow. By installing the first silencer 4 on the inner wall of the first silencer chamber 3 and the side wall of the air guide 5, the sound waves inside the first silencer chamber 3 can be scattered multiple times, and the propagation direction of the sound waves can be changed multiple times inside the first silencer chamber 3, so that the sound wave energy can be diffused and attenuated, thereby reducing the noise passing through the air duct body 1. By setting the fixing member 7 to a trapezoidal shape, the sound waves refracted inside the air duct body 1 can be more easily entered into the second silencer chamber 9 through the second vent 8. By installing the second silencer 10 inside the second silencer chamber 9, the sound waves can be reflected multiple times inside the second silencer chamber 9, so that the propagation direction can be changed, thereby diffusing and attenuating the energy, thereby reducing the sound waves at the air inlet and outlet of the air duct body 1.

[0037] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
