[0024] The following is a specific embodiment of the application and further describes the technical solution of the application in combination with the drawings, but the application is not limited to these embodiments.

[0025] In the description of the application, it should be understood that the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the application and simplifying the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the application.

[0026] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be a middle element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be a middle element.

[0027] For example, Figure 1 ​As shown, the automobile air outlet structure in the embodiment includes an air outlet assembly 10, an air duct 20 and a wind guide assembly 30. The air duct 20 is provided with the air outlet assembly 10 at one end and connected with the air outlet 11 of the air outlet assembly 10, and the other end is connected with the air outlet end of the automobile air conditioner. The wind guide assembly 30 is arranged in the air duct 20, so that the air blown out from the air outlet end of the automobile air conditioner passes through the air duct 20 and the wind guide assembly 30 in the air duct 20 and then is blown into the vehicle cabin through the air outlet assembly 10.

[0028] Specifically, when the automobile air outlet structure is installed, first, one end of the air duct 20 is welded to the instrument panel, so that the air duct 20 and the instrument panel become an integral whole, and one end of the air outlet 11 is connected to the instrument panel. Then, one end of the air outlet 11 is in contact with the other end of the air duct 20. Finally, a connecting structure is installed at the contact position of the air outlet 11 and the air duct 20, so that the air outlet 11 and the air duct 20 are fixed in position and tightly connected. Since the area of the instrument panel is large, the pipeline of the air duct 20 is long, and there are many other branches, the welding position of the one end of the air duct 20 and the instrument panel is not shown in the embodiment. Figure 1 The welding position of the one end of the air duct 20 and the instrument panel is not shown in the embodiment. Figure 1 The structure of the connecting mode is shown in the embodiment, which is not limited, and other structure forms of the connecting mode can also be selected to fix the air outlet 11 and the air duct 20 after they are in contact. The welding of the air duct 20 and the connection of the air outlet 11 are common prior art, which will not be described in detail.

[0029] The air outlet assembly 10 includes an air outlet 11, a sleeve 12, a plurality of wind guide vanes 13, a knob 14 and a rotating rod 15. In the embodiment, the air outlet 11 is annular and arranged on the panel of the automobile, the sleeve 12 is sleeved in the air outlet 11 and can rotate in the air outlet 11. The rotating rod 15 is arranged in the middle of the sleeve 12 in the axial direction, one end of the rotating rod 15 is connected with the knob 14, and the other end of the rotating rod 15 extends into the air duct 20 and is connected with the wind guide assembly 30. The wind guide vanes 13 are uniformly arranged in the sleeve 12, one end of the wind guide vane 13 is connected with the inner wall of the sleeve 12, and the other end of the wind guide vane 13 is connected with the rotating rod 15.

[0030] The wind guide assembly 30 includes a wind blocking part 31 and a wind guide part 32. The wind blocking part 31 is circular, and the circular wind guide plate makes the airflow entering the air duct more evenly, the airflow flow direction is spiral, forming a vortex, reducing noise. The wind blocking part 31 is connected with the other end of the rotating rod 15, so that the wind blocking part 31 can rotate under the driving of the rotating rod 15. The wind blocking part 31 is arranged perpendicular to the axial direction of the air duct 20, and is used to shield the air volume blown out from the air outlet end of the automobile air conditioner along the axial direction of the air duct 20. In other examples, the wind guide assembly 30 can also be other shapes adapted to the air duct 20.

[0031] Preferably, the wind blocking part 31 is provided with filter cotton on the side away from the air outlet 11, the filter cotton is circular in shape to fit the air duct 20, in other examples, the filter cotton can also be other shapes to fit the air duct. The filter cotton covers the wind blocking part 31 and closes the wind blocking part 31. Specifically, the filter cotton is a fine porous structure that blocks dust in the air from entering the air duct 20.

[0032] As shown in Figure 2 The air guide part 32 includes a plurality of air guide blades 322 extending radially outward along the center of the wind blocking part 31, avoiding rotation of the air guide blades in the air guide plate, affecting the airflow direction and distribution, and avoiding more mechanical and airflow noise. The air guide blades 322 are vertically arranged on the side of the wind blocking part 31 close to the air outlet 11, and the air guide chambers are formed between adjacent two air guide blades 322 and the wind blocking part. The outer edge of the air guide chamber forms an air guide outlet 321. The air guide part 32 is used to blow the air volume blocked by the wind blocking part 31 out of the air guide outlet 321 in the radial direction of the air duct. Moreover, the arrangement density of the air guide blades 322 along the circumferential direction of the air guide part 32 gradually decreases or gradually increases, so that the air guide volume of the air guide outlet 321 gradually decreases or gradually increases along the circumferential direction of the air guide part 32.

[0033] The wind blocking part 31 and the air guide part 32 are integrally formed, which is convenient for processing of the air guide assembly 30 and can effectively improve the strength of the air guide part to avoid collision noise due to vibration of each component caused by the impact of airflow.

[0034] The air duct 20 has a first reducing section in the direction from the air guide assembly 30 to the air outlet 11, and the cross-sectional area of the first reducing section gradually decreases in the direction from the air guide assembly 30 to the air outlet 11. The air duct 20 has a second reducing section in the direction from the air guide assembly 30 to the air outlet end of the automobile air conditioner, and the cross-sectional area of the second reducing section gradually decreases in the direction from the air guide assembly 30 to the air outlet end of the automobile air conditioner. The air duct 20 forms an air guide slope, and the airflow flows more quickly.

[0035] In use, the air outlet structure of the automobile of the above embodiment, the air sent by the air outlet end of the automobile air conditioner flows into the air guide assembly 30 through the air duct 20, enters the air baffle part 31 after being filtered by the filter cotton, at this time, the air flow is divided into each air guide chamber by the air guide vane 322, due to the blockage of the air baffle part 31, the air flow is reversed, and flows out of the air guide assembly 30 along the air guide vane 322 through the air guide outlet 321 at the outer edge of the air guide chamber. By guiding the flow through the air guide assembly 30, the originally axial air flow into the air duct 20 is dispersed to the surrounding into the air duct 20 between the air guide assembly 30 and the air outlet assembly 10, and forms a vortex in the air duct. By dispersing the air flow and forming a vortex, the air flow noise is effectively reduced. Since the sizes of the air guide outlets 321 are different, the air outlet volume at different positions of the air guide part 32 is also different, and then the user can adjust the air volume of a certain position of the air outlet by adjusting the knob, and then the air flow flows into the vehicle cabin through the air outlet of the air outlet assembly.

[0036] Compared with the prior art, the air outlet structure of the automobile of the embodiment of the present application disperses the air directly into the air duct to the surrounding, forms a vortex, and then enters the air outlet, thereby reducing the air noise in the air duct. By setting the sizes of the air guide outlets to be different, the user can conveniently adjust the air outlet volume and direction.

[0037] The above-described embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it cannot be understood as limiting the scope of the patent. It should be noted that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of protection of the present application.
