Turbulent flow structure and automobile wind-feeling-free air outlet

Abstract

The utility model provides a spoiler structure and an automobile wind-feeling-free air outlet. The spoiler structure comprises a middle shaft and a plurality of spoilers arranged on the middle shaft. When air flow passes through the air channel, the air flow needs to penetrate through the spoilers, and when the central axis faces of the spoilers are arranged to form acute angles or obtuse angles relative to the central axis, and the spoilers with certain angles rotate, the air flow penetrating through the spoilers can be continuously disturbed, and the direction of the air flow is continuously changed. When the air flow disturbed by the spoiler is led out from the air duct, the blowing disturbance feeling to passengers is weakened, so that the air duct still has a strong wind-feeling-free function under the condition that the occupied space of the air duct is small.

Description

Technical Field

[0001] The utility model relates to the technical field of automobile air outlets, and particularly relates to a flow disturbing structure and an automobile air outlet without wind feeling. Background Art

[0002] The air outlet without wind feeling of an automobile is designed to send the air blown out by the air conditioner into the carriage and reduce the passengers' perception of the wind, that is, it can provide the temperature adjustment effect of the air conditioner at a relatively high wind speed, and at the same time minimize the blowing feeling of the wind on the passengers.

[0003] The Chinese invention patent application discloses a three-channel air outlet without wind feeling (CN117755051A), which includes an upper air duct and a lower air duct for blowing conventional air, and a diversion air duct for blowing air without wind feeling. 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 multiple through holes on the multiple soft wind plates, thereby reducing the blowing feeling of the wind on the passengers.

[0004] However, when the cross-sectional shape of the wind guiding cavity of the diversion air duct is trapezoidal in the first direction, the wind diverges to both sides along the two waists of the trapezoid; but the space left for the air outlet inside the automobile is limited, resulting in that the angles of the two waists of the trapezoid cannot be made larger, and further resulting in poor divergence effect when the wind passes through the two waists of the trapezoid, and finally the function of the air outlet without wind feeling is weak. Summary of the Utility Model

[0005] The problem to be solved by the utility model is to provide a flow disturbing structure and an automobile air outlet without wind feeling that can still have a strong function of the air outlet without wind feeling when the occupied space of the air duct is small.

[0006] The technical solution adopted by the utility model to solve the above problems is as follows: a flow disturbing structure, including:

[0007] A central axis, wherein the central axis is arranged at both ends of the air duct; the central axis has a central axis line; and

[0008] A plurality of flow disturbing plates, wherein the flow disturbing plates are arranged in multiple pieces and are spaced at intervals along the length direction of the central axis; the flow disturbing plates have a central axis plane, and the central axis plane is arranged to be at an acute angle or an obtuse angle relative to the central axis line;

[0009] When the central axis rotates in the air duct, the multiple flow disturbing plates rotate synchronously so as to disturb the air flow in the air duct.

[0010] Compared with the prior art, the utility model includes a central axis and a plurality of the spoiler vanes arranged on the central axis; when the air flow passes through the air duct, it needs to pass through the plurality of spoiler vanes. When the central plane of the plurality of spoiler vanes is set to be an acute angle or an obtuse angle relative to the central axis, and these spoiler vanes with a certain angle rotate, the air flow passing through the spoiler vanes can be continuously disturbed and its direction can be continuously changed. When the air flow disturbed by the spoiler vanes is led out from the air duct, the blowing and disturbing feeling for passengers is weakened, so that under the condition of a small occupied space of the air duct, it still has a strong function of no-wind feeling.

[0011] A spoiler structure of the utility model, wherein the central plane of the spoiler vane is configured as a rectangle; the plurality of spoiler vanes are arranged on the central axis in a manner that the central plane forms various angles with the central axis; when the central axis rotates in the air duct, the air flow is disturbed at various angles.

[0016] A transmission part, which is arranged at one end of the central axis and is used for connecting with an external power source;

[0017] A connecting part, which is used for rotatably connecting with the side wall of the air duct.

The object of the present utility model has been fully and effectively achieved. The functions and structural principles of the present utility model have been demonstrated and explained in the embodiments. Without departing from the above principles, the embodiments of the present utility model can have any deformation or modification.

[0033] The embodiments of the present utility model will be further described below with reference to the drawings.

[0034] Please refer to Figures 1-9 a spoiler structure shown in the figure, which includes a central axis 1 and a plurality of spoiler vanes 2; wherein the central axis 1 is arranged at both ends of the air duct; the central axis 1 has a central axis line 11; wherein the spoiler vanes 2 are arranged in multiple pieces and are spaced along the length direction of the central axis 1; the spoiler vanes 2 have a central plane 21, and the central plane 21 is arranged to be at an acute angle or an obtuse angle relative to the central axis line 11; when the central axis 1 rotates in the air duct, the multiple spoiler vanes 2 rotate synchronously to disturb the air flow in the air duct.

[0035] In actual use, the present utility model includes the central axis 1 and a plurality of spoiler vanes 2 arranged on the central axis; when the air flow passes through the air duct, it needs to pass through the plurality of spoiler vanes 2. When the central plane 21 of the plurality of spoiler vanes 2 is arranged to be at an acute angle or an obtuse angle relative to the central axis line 11 and these spoiler vanes 2 with a certain angle rotate, the air flow passing through the spoiler vanes 2 can be continuously disturbed and its direction can be continuously changed. When the air flow disturbed by the spoiler vanes 2 is led out from the air duct, the blowing feeling on the passengers is weakened, so that even when the space occupied by the air duct is small, it still has a strong no-wind feeling function.

[0036] Please continue to refer to Figures 1-4 , wherein, the central plane 21 of the spoiler vane 2 is configured as a rectangle; the plurality of spoiler vanes 2 are arranged on the central axis 1 in such a way that the central plane 21 forms multiple angles with the central axis 1; when the central axis 1 rotates in the air duct, the air flow is disturbed at multiple angles.

[0037] Specifically, the central axis plane 21 of the spoiler 2 is configured as a rectangle with rounded corners at four corners, the length of the rectangle is greater than the width, and the included angles between the central axis planes 21 of multiple spoilers 2 and the central axis 1 are different from each other, thereby forming multiple sub-air ducts with different sizes and angles in the air duct; when the central axis 1 rotates in the air duct, the air flow passes through these sub-air ducts with different sizes and angles, and the flow velocities of each air flow will be different, and due to different angles, the air flows will also 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.

[0038] It can be understood that when the central axis plane 21 of the spoiler 2 is configured as an ellipse and the included angles between the central axis planes 21 of multiple spoilers 2 and the central axis 1 are different from each other, multiple sub-air ducts with different sizes and angles can also be formed in the air duct.

[0039] Please further refer to Figures 1-4 , wherein, multiple spoilers 2 on the central axis 1 are arranged to rotate around the central axis line 11 at a fixed angular pitch; multiple spoilers 2 take 180° as a cycle and evenly divide the 180° stroke; the distance between two spoilers 2 is set to be 10 - 15 cm.

[0040] Such as Figure 3 , 4 As shown in, specifically, for this embodiment, the spoiler 2 is set to be 9, the axis included angle between every two spoilers 2 is 20°, and 9 spoilers 2 are a cycle, that is, 180°; and, the distance between two spoilers 2 is set to be 10 - 15 cm; for the automobile air outlet, such settings of the number of spoilers 2, the angle difference between adjacent spoilers 2, and the distance between adjacent spoilers 2 can take into account both the production difficulty and the spoiler function.

[0041] Please continue to refer to Figures 6-8 , wherein, the central axis plane 21 of the spoiler 2 is configured with a circular cross-section, and multiple spoilers 2 are arranged at the same angular interval; when the central axis 1 rotates in the air duct, the air flow is disturbed at the same angle.

[0042] Specifically, when the central axis plane 21 of the spoiler 2 is configured with a circular cross-section and multiple spoilers 2 are arranged at the same angular interval, in this setting, when the central axis 1 rotates in the air duct, the air flow is disturbed by the spoilers 2 at the same angle, thereby reducing the blowing feeling when the wind blows out from the air duct; compared with the rectangular spoilers 2 at different angles, the spoiler function of the circular spoilers 2 at the same angle is relatively weak.

[0043] However, as Figure 9As shown, when at rest, multiple spoiler vanes 2 rest at the same angle. Equal sub-air ducts are formed between two spoiler vanes 2 that are identical in shape and circular, and these sub-air ducts can guide the airflow to change direction, so that the air blown out from the air duct faces the angle required by the user.

[0044] Please continue to refer to Figure 2 、 Figure 6 , which further includes a transmission part 3 and a connection part 4; the transmission part 3 is arranged at one end of the central shaft 1 and is used to connect with an external power source; the connection part 4 is used for rotatably connecting with the side wall of the air duct; when the external power source applies power, it can drive the central shaft 1 to rotate, and then drive multiple spoiler vanes 2 arranged on the central shaft 1 to rotate and generate turbulence.

[0045] Please continue to refer to Figure 5 , wherein the transmission part 3 includes a gear clamping rod 31 and a limiting disk 32 arranged at the outer end of the gear clamping rod 31; the gear clamping rod 31 has a connection groove 311.

[0046] During assembly, the shaft part of the external power source gear is inserted into the connection groove 311 along the A direction and forms a tight connection with the gear clamping rod 31 to drive the central shaft 1 to rotate.

[0047] Please continue to refer to Figures 6-8 , wherein the transmission part 3 includes a transmission gear 33, and the transmission gear 33 is used to connect with an external power source; during use, the gear of the external power source can drive the central shaft 1 to rotate by meshing with the transmission gear 33.

[0048] As Figure 9 shown, an air outlet of an automobile without wind feeling includes the spoiler structure as described above.

[0049] The above only describes the best embodiments of the present invention, but it should not be construed as a limitation on the claims. The present invention is not limited to the above embodiments, and its specific structure allows changes. All changes made within the protection scope of the independent claims of the present invention are within the protection scope of the present invention.
