[0038] like Figure 1-12 As shown, in one embodiment of the present invention, an electric face-blowing air outlet assembly for an automobile is provided, comprising a housing 10, a guide door 20, a first drive member 30, a damper 40, a clutch transmission assembly 50, a limit member 60, and an unlocking member 70. An air inlet duct 11 and two air outlet ducts 12 are provided within the housing 10. The two air outlet ducts 12 are arranged on the same side and are respectively connected to the air inlet duct 11. The guide door 20 is rotatably disposed within the air inlet duct 11. The guide door 20 is used to partially block or close the air inlet end of one of the air outlet ducts 12, or to fully open the air inlet ends of both air outlet ducts 12.

[0039] The first driving member 30 is mounted on the housing 10, and the first driving member 30 is used to drive the guide door 20 to rotate. The damper 40 is rotatably arranged in the air inlet channel 11, and the damper 40 is used to open or close the air inlet end of the air inlet channel 11. The clutch transmission assembly 50 is used to disconnect or restore the connection between the guide door 20 and the damper 40. When the guide door 20 is connected to the damper 40, the damper 40 rotates following the guide door 20. When the guide door 20 is disconnected from the damper 40, the guide door 20 fully opens the air inlet ends of the two air outlet channels 12, and the damper 40 is at its maximum opening. The limiting member 60 is used to lock the damper 40 when the guide door 20 and the damper 40 are disconnected, so that the damper 40 maintains its maximum opening. The unlocking member 70 is used to release the restriction of the limiting member 60 on the damper 40 when the guide door 20 is restored to its connection with the damper 40.

[0040] See Figure 6When guide door 20 is in its initial position, damper 40 closes the air inlet end of air inlet channel 11. For ease of description, one outlet channel 12 near the initial position of guide door 20 is designated as outlet channel 12a. Outlet channel 12a communicates with air inlet channel 11 via air inlet 13a. The other outlet channel 12 is designated as outlet channel 12b. Outlet channel 12b communicates with air inlet channel 11 via air inlet 13b.

[0041] See Figure 6-11 When the first driving member 30 drives the guide door 20 to rotate from its initial position, the damper 40, under the action of the clutch transmission assembly 50, also rotates with the guide door 20. This causes the damper 40 to gradually open the air inlet end of the air inlet channel 11. Simultaneously, the guide door 20 gradually blocks the air inlet 13a, allowing airflow to enter the air inlet channel 11 and flow toward both the air inlets 13a and 13b. Because the air inlet 13a is blocked by the guide door 20, the majority of the airflow flows toward the air inlet 13b, while a smaller portion flows toward the air inlet 13a. Consequently, the air volume discharged from the air outlet channel 12b is greater than that discharged from the air outlet channel 12a.

[0042] The guide door 20 continues to rotate toward the air inlet 13b, and the guide door 20 will completely block the air inlet 13a (see Figure 8 ), at this time, the opening of the damper 40 becomes larger, and the air flow basically only flows to the air inlet 13b. When the guide door 20 rotates to the position between the air inlet 13a and the air inlet 13b (see Figure 9 ), the guide door 20 fully opens the two air inlets 13a and 13b, and the damper 40 is also at its maximum opening, so that air flows to the air inlets 13a and 13b respectively, and the air volumes blown out of the air outlet channels 12a and 12b are substantially the same. At this point, the guide door 20 and the damper 40 are in a critical disconnected state.

[0043] When the first driving member 30 continues to drive the guide door 20 to rotate toward the air inlet 13b, the clutch transmission assembly 50 disconnects the guide door 20 from the damper 40, and the limiter 60 locks the damper 40 to maintain its maximum opening. The guide door 20 will gradually block the air inlet 13b (see Figure 11 ), most of the airflow will flow toward the air inlet 13a, and a small amount will flow toward the air inlet 13b. Thus, the air volume blown out of the air outlet 12a is greater than the air volume blown out of the air outlet 12b. The guide door 20 continues to rotate toward the air inlet 13b, completely blocking the air inlet 13b. At this time, the damper 40 remains at its maximum opening, and the airflow essentially flows only toward the air inlet 13a.

[0044] When the first driving member 30 drives the guide door 20 toward its initial position, and when the guide door 20 reaches a position between the air inlet 13a and the air inlet 13b (the guide door 20 rotates approximately 90° from its initial position to this position), the guide door 20 and the damper 40 are in a critical state of reconnection. With further rotation, the clutch transmission assembly 50 restores the connection between the guide door 20 and the damper 40, and the unlocking member 70 releases the restraint on the damper 40 by the stopper 60, allowing the damper 40 to rotate with the guide door 20 and gradually close the air inlet end of the air inlet passage 11.

[0045] The present embodiment discloses an electric face-blowing air outlet assembly for an automobile, which controls the connection status of the guide door 20 and the air door 40 by designing a clutch transmission component 50, utilizes a limiter 60 to keep the air door 40 at its maximum opening, and utilizes an unlocking member 70 to release the restriction of the limiter 60 on the air door 40. Through the mutual cooperation of various components, the electric face-blowing air outlet assembly for an automobile can guide the direction of airflow according to usage requirements, thereby achieving adjustment of the air outlet position and air volume of the two air outlet channels 12, thereby improving functionality and user experience.

[0046] In one embodiment, the clutch transmission assembly 50 includes a meshable first gear 51 and a second gear 52. Both the first gear 51 and the second gear 52 are incomplete gears. The first gear 51 is connected to the guide door 20, and the second gear 52 is rotatably connected to the damper 40. A stopper 60 is used to secure the second gear 52 when the first gear 51 and the second gear 52 are disengaged. An unlocking member 70 is provided on the first gear 51 and is used to disengage the stopper 60 from the second gear 52 when the first gear 51 and the second gear 52 resume meshing.

[0047] Furthermore, the stopper 60 is an elastic sheet provided on the housing 10, and the second gear 52 is provided with a stopper 53 that cooperates with the elastic sheet. The unlocking member 70 is a cam arranged coaxially with the first gear 51, and the raised portion of the cam can push against the elastic sheet to disengage the stopper 53.

[0048] When the guide door 20 is located between the air inlet 13a and the air inlet 13b, if the guide door 20 rotates toward the air inlet 13b, the first gear 51 and the second gear 52 will be disengaged, and the elastic sheet will abut against the limiting portion 53 of the second gear 52. In this way, the elastic sheet will keep the second gear 52 in this state, thereby keeping the damper 40 at the maximum opening.

[0049] During the process of the guide door 20 rotating toward the initial position, when the first gear 51 and the second gear 52 re-engage, the protrusion of the cam on the first gear 51 will push away the elastic sheet, so that the second gear 52 will drive the damper 40 to rotate along with the guide door 20.

[0050] In one embodiment, the limiting portion 53 extends toward the end face of the second gear 52. This structural design can increase the contact area between the limiting portion 53 and the elastic sheet. When the elastic sheet abuts against the limiting portion 53, the mutual contact area is relatively large, which enhances the locking effect of the elastic sheet on the second gear 52.

[0051] In one embodiment, the damper 40 includes a first door body 41 and a second door body 42, and the clutch transmission assembly 50 also includes a third gear 54 and a fourth gear 55 that are meshed with each other. The third gear 54 and the fourth gear 55 are respectively connected to the first door body 41 with the third gear 54 and the second gear 52, and the fourth gear 55 is connected to the second door body 42.

[0052] In one embodiment, the first gear 51 is disposed between the guide door 20 and the first drive member 30, and is connected to the first drive member 30. The third gear 54 is disposed between the second gear 52 and the third gear 54. The third gear 54 and the fourth gear 55 are disposed within the air inlet duct 11, while the first gear 51 and the second gear 52 are disposed outside the housing 10. This structural design reduces the space occupied by the clutch transmission assembly 50, making the overall structure of the automotive electric face-blowing air outlet assembly more compact.

[0053] In one embodiment, the housing 10 is provided with two air outlets 14, each connected to a corresponding air outlet channel 12. An ambient light strip 15 is positioned between the two air outlets 14. The ambient light strip 15 displays a corresponding color based on the cool or hot air being blown out of the air outlet 14, and can also display varying brightness levels based on the air volume. This not only enhances the overall aesthetics of the electric front-facing air outlet assembly but also improves the user experience. The operating principle of the ambient light strip 15 is conventional and will not be further described in this embodiment.

[0054] In one embodiment, the electric face-blowing air outlet assembly for an automobile further includes a second drive member 80 and two blade assemblies 90. Each blade assembly 90 is disposed within a corresponding air outlet duct 12. The second drive member 80 is disposed on the housing 10 and is configured to synchronously drive the two blade assemblies 90 to adjust the airflow direction of the corresponding air outlet 14. Both the second drive member 80 and the first drive member 30 are motors, both of which are also bolted to the housing 10. Driven synchronously by the second drive member 80, the two blade assemblies 90 can adjust the airflow direction of the corresponding air outlet 14, thereby enhancing the functionality and practicality of the electric face-blowing air outlet assembly for an automobile.

[0055] In summary, the electric air outlet assembly for automobile provided by the present invention includes four working modes. In actual application, the two air outlets 14 of the housing 10 can realize left-right sweeping or up-down sweeping.

[0056] Taking the two air outlets 14 of the housing 10 to achieve left and right air sweeping as an example, the first working mode is left and right circular air sweeping, that is, when the first driving member 30 drives the guide door 20 to move to the position between the air inlet 13a and the air inlet 13b (when the guide door 20 rotates from the initial position to this position, the angle of rotation is close to 90°), the damper 40 is fully opened. At the same time, the initial position of the blade assembly 90 can be the middle position or the left extreme position or the right extreme position. Taking the initial position of the blade assembly 90 as the middle position as an example, the second driving member 80 can control the rotation path of the blade assembly 90 to be: middle position-left extreme position-right extreme position-middle position, to achieve a cycle, and so on, to achieve left and right circular air sweeping.

[0057] The second working mode: rapid cooling of the blowing surface, that is, the first driving member 30 controls the guide door 20 to move between the air inlet 13a and the air inlet 13b and remain stationary (when the guide door 20 moves from the initial position to this position, the rotation angle is close to 90°), and the second driving member 80 controls the blade assembly 90 to rotate to the middle position and remain stationary.

[0058] The third working mode: avoiding people from being blown by the wind, that is, the first driving member 30 controls the guide door 20 to move to the air inlet 13b and block the air inlet 13b, and the second driving member 80 controls the blade assembly 90 to rotate to the left limit position or the right limit position and keep it stationary.

[0059] The fourth working mode: the free mode of inching, that is, manually pressing the switch button of the second driving member 80 to control the blade assembly 90 to rotate to the desired position, and then releasing the switch button of the second driving member 80, the air outlet direction of the blade assembly 90 is locked at the aforementioned desired position.

[0060] The above four working modes basically meet most of the use needs of the passengers. Of course, this technical solution is not limited to these four working modes, and the mode can also be adjusted according to the use needs of the passengers.

[0061] In the specification of the present invention, a large number of specific details are described. However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
