[0003] The Chinese invention patent application discloses a three-channel windless air outlet (CN117755051A), which includes an upper air duct and a lower air duct for blowing conventional air, and a diversion air duct for blowing windless air. The diversion air duct includes a wind guiding cavity and a soft wind plate. The cross-sectional shape of the wind guiding cavity in the first direction is trapezoidal. When the wind passes through the diversion air duct, it diverges to both sides along the two waists of the trapezoid. When the wind flows to the soft wind plate, it is blown out from a plurality of through holes on the plurality of soft wind plates, thereby reducing the blowing feeling of the wind on the passengers.

[0033] The following further describes the embodiments of the present utility model with reference to the drawings.
[0034] Please refer to Figures 1-9 A windless air duct structure as shown, comprising an air inlet assembly 1, an air outlet assembly 2, and a flow disturbance assembly 3; wherein the air inlet assembly 1 includes a narrow air section 11 and a diffuser section 12 with a dimension in the height direction larger than that of the narrow air section 11; wherein the air outlet assembly 2 is disposed in the diffuser section 12; the dimension of the air outlet assembly 2 in the height direction is larger than that of the diffuser section 12; the air outlet assembly 2 includes a windless air outlet surface 21; wherein the flow disturbance assembly 3 is rotatably disposed in the air inlet assembly 1; air enters from the narrow air section 11, is disturbed by the flow disturbance assembly 3 and then enters the air outlet assembly 2, and is blown out from the windless air outlet surface 21.
[0035] Please continue to refer to Figure 2 、 Figure 9 When actually in use, the present utility model includes an air inlet assembly 1 and an air outlet assembly 2. Air enters through the air inlet assembly 1 and is blown out through the air outlet assembly 2. Among them, a flow disturbance assembly 3 is provided in the air inlet assembly 1. When the air passes through the flow disturbance assembly 3, it is disturbed, thereby increasing the no-wind feeling function for the first time without affecting the width direction. The air inlet assembly 1 includes a narrow air section 11 and a wind expansion section 12. The dimension of the wind expansion section 12 in the height direction is greater than that of the narrow air section 11 and is connected to the air outlet assembly 2 with a larger dimension in the height direction. When the air enters the air outlet assembly 2 from the narrow air section 11 through the wind expansion section 12, the air is diffused in the height direction, thereby increasing the no-wind feeling function for the second time without affecting the width direction. The air outlet assembly 2 includes a no-wind feeling air outlet surface 21. When the air passes through the air outlet assembly 2, it finally blows out from the no-wind feeling air outlet surface 21. Under the partitioning action of the no-wind feeling air outlet surface 21, the present utility model increases the no-wind feeling function for the third time without affecting the width direction.
[0036] Please continue to refer to Figure 3 Among them, the narrow air section 11 has a first air inlet 111, and the wind expansion section 12 has a first air outlet 121; the air outlet assembly 2 has a second air inlet 22, and the second air inlet 22 cooperates with the first air outlet 121.
[0037] Specifically, the first air inlet 111 can be directly connected to the air supply system of the vehicle, or can be used as one of the air ducts in the vehicle air outlet assembly, so that the present utility model can convert the normal air provided by the air supply system into no-wind feeling air with a lower blowing disturbance to the user.
[0038] Please continue to refer to Figure 1 、 Figure 2 Among them, the position of the second air inlet 22 is set to correspond to the no-wind feeling air outlet surface 21, so that the air enters from the second air inlet 22 and blows out from the no-wind feeling air outlet surface 21; under this setting, it is beneficial for the air flow to smoothly pass through the three structures that increase the no-wind feeling effect composed of the flow disturbance assembly 3, the wind expansion section 12, and the no-wind feeling air outlet surface 21.
[0039] Please continue to refer to Figure 1 、 Figure 2 、 Figure 3, in some embodiments, the air outlet assembly 2 includes a drum part 23 and at least one wind deflector surface 24; the draft-free air outlet surface 21 and the second air inlet 22 are respectively arranged on the front and rear corresponding surfaces of the drum part 23, and the wind deflector surface 24 is arranged between the draft-free air outlet surface 21 and the second air inlet 22; both ends of the drum part 23 are arranged to be rotatably connected to the wind expansion section 12; during use, the drum part 23 can be connected to a power mechanism. For example, an actuator for controlling the rotation angle of the drum part 23 is arranged at one end of the drum part 23. When the actuator controls the wind deflector surface 24 to cooperate with the first air outlet 121, the air duct is closed, and when the actuator controls the second air inlet 22 to cooperate with the first air outlet 121, the air duct is opened, so as to control the opening and closing of the air duct of the present invention; in addition, through the rotation of the power mechanism, continuous rolling of the drum part 23 or hovering at a certain angle can also be achieved, so as to realize up and down air sweeping or up and down blowing at any angle.
[0040] It can be understood that, in some other embodiments, the drum part 23 can also be set to be non-rotatable. This setting can make the structure of the present invention simpler, with lower manufacturing cost, and can also constitute a three-way structure for increasing the draft-free effect composed of the turbulence generating component 3, the wind expansion section 12 and the draft-free air outlet surface 21, so as to provide an accessory option for vehicles with lower cost.
[0041] Please continue to refer to Figure 4 , Figure 5 , wherein the draft-free air outlet surface 21 has a plurality of air outlet holes 211; the area of the air outlet holes 211 gradually decreases from the central axis of the draft-free air outlet surface 21 to both ends, so that when the air flow passes through the draft-free air outlet surface 21, it is cut into multiple sub-air flows by the plurality of air outlet holes 211, thereby reducing the blowing disturbance to the user; further, when the area of the air outlet holes 211 gradually decreases from the central axis of the draft-free air outlet surface 21 to both ends, it can make the pressures of the multiple sub-air flows blown out from different air outlet holes 211 different, and these sub-air flows with different pressures disturb each other, thereby further reducing the blowing disturbance to the user.
[0042] Please continue to refer to Figure 4 , in some embodiments, the width dimension of the wind expansion section 12 is larger than that of the narrow wind section 11; the present invention makes the air flow expand in the height direction. When the interior space of the vehicle permits, the width dimension of the wind expansion section 12 can be designed to be larger than that of the narrow wind section 11. This setting can enable the air flow to expand in both the height and width directions when entering the wind expansion section 12 from the narrow wind section 11, thereby making the draft-free effect better.
[0043] Please continue to refer to Figures 6-8, wherein, the spoiler assembly 3 includes a rotating shaft 31 rotatably connected to both ends of the narrow air section 11 and a plurality of spoiler vanes 32 arranged at intervals along the length direction of the rotating shaft 31; further, the central plane of the spoiler vane 32 is configured as a rectangle; the plurality of spoiler vanes 32 are arranged at various angles with respect to the rotating shaft 31 through the central plane; when the rotating shaft 31 rotates within the narrow air section 11, the air flow is disturbed at various angles; further, the plurality of spoiler vanes 32 on the rotating shaft 31 are arranged to rotate around the rotating shaft 31 at a fixed angular pitch; the plurality of spoiler vanes 32 take 180° as a cycle and evenly divide the 180° stroke; the distance between two spoiler vanes 32 is set to 10 - 15 cm.
[0044] In actual use, the central plane of the spoiler vane 32 is configured as a rectangle with rounded corners at the four corners, the length of the rectangle is greater than the width, and the included angles between the central planes of the plurality of spoiler vanes 32 and the rotating shaft 31 are different from each other, thereby forming a plurality of sub-air ducts with different sizes and angles in the air duct; when the rotating shaft 31 rotates within the air duct, the air flow passes through these sub-air ducts with different sizes and angles, the flow velocities of each air flow will be different, and due to the different angles, the air flows will interfere with each other, making the spoiler effect of the present invention better, and the blowing feeling of the air flow blown out from the air duct to the passengers is smaller.
[0045] And as Figure 7 , Figure 8 shown, for this embodiment, the spoiler vanes 32 are set to 9, the axis included angle between every two spoiler vanes 32 is 20°, and 9 spoiler vanes 32 are a cycle, that is, 180°; the distance between two spoiler vanes 32 is set to 10 - 15 cm; for the automotive air outlet, such a setting of the number of spoiler vanes 32, the angle difference between adjacent spoiler vanes 32, and the distance between adjacent spoiler vanes 32 can take into account both the production difficulty and the spoiler function.
[0046] An automotive air outlet includes the no-wind-sensation air duct structure as described above.
[0047] The above is only an illustration of the best embodiment of the present invention, but it should not be construed as a limitation to the claims. The present invention is not limited to the above embodiments, and its specific structure allows changes. Any changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
