Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically to an automotive air vent. Background Technology

[0002] Car air vents are an important part of the car's interior and play a significant role in the comfort of the driving experience. Car air vents need to meet the functional requirements of adjusting airflow direction and volume, and ensuring a tight seal.

[0003] Currently, dual-channel air outlets, such as the non-parallel dual-channel electric air outlet disclosed in publication number CN219214664U, require separate air guide modules for each channel. These air guide modules include upper and lower air guide modules, left and right air guide modules, and damper modules. The airflow direction is adjusted by the air guide vanes of these modules, resulting in direct airflow to the user, leading to a poor user experience. Furthermore, the structure is complex and contains numerous components. Utility Model Content

[0004] To address the shortcomings and defects of existing technologies, a compact, simple, and user-friendly automotive air vent is provided.

[0007] As an improvement of this utility model, the fluid oscillator includes a turbulence duct extending in a gradually expanding structure along the center line C, a first return duct disposed on the left side of the turbulence duct, and a second return duct disposed on the right side of the turbulence duct.

[0009] The outlet aa of the first return air duct and the outlet bb of the second return air duct are positioned opposite each other at the front of the inlet of the turbulence air duct and are respectively connected to the turbulence air duct.

[0010] The inlet of the turbulence duct is used to receive the airflow from the outlet duct, as well as the airflow returning from the first return duct and the second return duct. The outlet of the turbulence duct serves as the outlet of the fluid oscillator.

[0011] With the above structure, the automobile air vent of this utility model has the following advantages compared with the prior art: the air outlet channel is equipped with a fluid oscillator, the airflow in the air outlet channel enters the fluid oscillator, and after being acted upon by the fluid oscillator, the oscillating airflow is discharged from the outlet and finally passes through the air outlet end to act on the outside.

[0012] Compared to existing sweeping air outlets, this device eliminates the need for continuously moving guide vanes to change the airflow direction. Instead, it outputs oscillating airflow through a fluid oscillator. This oscillating airflow can sweep within a certain range (similar to the guidance of guide vanes), achieving a wider airflow range. Furthermore, the oscillated airflow has an airflow effect similar to natural wind (avoiding direct airflow that could negatively impact the user experience), thus improving the user experience. In addition, this device features a simple structure and high reliability.

[0017] A gap is provided between the tail end of the guide vane on the right and the tail end of the baffle as the inlet b, and a gap is provided between the front end of the guide vane on the right and the front end of the baffle as the outlet bb.

[0018] As an improvement of this utility model, after the front ends of the two partitions converge inward, a converging air duct with a gradually contracting structure along the center line C is formed between them. The inlet of the converging air duct is used to receive the airflow from the outlet air duct, and the outlet of the converging air duct is arranged opposite to the inlet of the turbulence air duct.

[0022] As an improvement of this utility model, the inlet of the first air duct, the inlet of the second air duct, and the inlet of the converging air duct are located in the same plane.

[0023] A first connecting shaft is provided between the inlet of the first air duct and the inlet of the converging air duct. A first air duct damper and a converging air duct damper a are rotatably connected to the first connecting shaft.

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0035] Please see Figure 1-6 As shown, a car air vent includes:

[0036] The air outlet housing 1 is provided with an air outlet channel 1.1, and the air outlet channel 1.1 is provided with an air outlet end 1.11. A fluid oscillator 2 is provided inside the air outlet channel 1.1. The outlet 2.11 of the fluid oscillator 2 is arranged opposite to the air outlet end 1.11. The airflow entering the air outlet channel 1.1 is discharged to the outside through the air outlet end 1.11 after being acted upon by the fluid oscillator 2.

[0037] The air outlet duct 1.1 is equipped with a fluid oscillator 2. The airflow in the air outlet duct 1.1 enters the fluid oscillator 2, and after being acted upon by the fluid oscillator 2, the oscillating airflow is discharged from the outlet 2.11 and finally passes through the air outlet 1.11 to act on the outside.

[0038] Compared with existing sweeping air outlets, this device does not require continuously moving guide vanes to change the air direction. Instead, it outputs an oscillating airflow through the fluid oscillator 2. This oscillating airflow can sweep within a certain range (similar to the airflow guided by guide vanes), thus achieving a wider air outlet range. Furthermore, the oscillating airflow has an air outlet effect similar to natural wind (avoiding direct airflow that could lead to a poor user experience), improving the user experience. In addition, this device is characterized by its simple structure and high reliability.

[0039] As an improvement of this utility model, the fluid oscillator 2 includes a turbulence duct 2.1 extending in a gradually expanding structure along the center line C, a first return duct 2.2 disposed on the left side of the turbulence duct 2.1, and a second return duct 2.3 disposed on the right side of the turbulence duct 2.1;

[0040] The inlet a2.21 of the first return air duct 2.2 and the inlet b2.31 of the second return air duct 2.3 are arranged opposite to each other at the front of the outlet 2.11 of the turbulence air duct 2.1, and are respectively connected to the turbulence air duct 2.1;

[0041] The outlet aa2.22 of the first return air duct 2.2 and the outlet bb2.32 of the second return air duct 2.3 are arranged opposite to each other at the front of the inlet of the turbulence air duct 2.1 and are respectively connected to the turbulence air duct 2.1;

[0042] The inlet of the turbulence duct 2.1 is used to receive the airflow from the outlet duct 1.1, as well as the airflow returned from the first return duct 2.2 and the second return duct 2.3. The outlet 2.11 of the turbulence duct 2.1 serves as the outlet 2.11 of the fluid oscillator 2.

[0043] After the above improvements, the inlet of the turbulence duct 2.1 receives the main airflow of the outlet duct 1.1.

[0044] The main airflow may be split at the outlet 2.11 of the turbulence duct 2.1, and may enter the inlet a2.21 or the inlet b2.31;

[0045] When the inlet airflow at inlet a2.21 is greater than the inlet airflow at inlet b2.31, the airflow exits from outlet aa2.22 through the first return air duct 2.2, pushing the airflow entering the turbulence duct 2.1 further away. After interacting with the airflow entering through the inlet of the turbulence duct 2.1, the airflow gathers in the upper region of the turbulence duct 2.1, pushing the main airflow in the turbulence duct 2.1 further away (downward shifting to cross the centerline). Then, after the main airflow passes through the outlet 2.11 of the turbulence duct 2.1, which is located at the center, it can change the output direction of the airflow (the airflow output from the outlet 1.11 shifts upward).

[0046] In addition, the shifted main airflow can enter inlet b2.31 in larger quantities to achieve the next cycle;

[0047] When the airflow entering through inlet b2.31 is greater than the airflow entering through inlet a2.21, the airflow exits through outlet bb2.32 via the second return duct 2.3, pushing the airflow entering the turbulence duct 2.1 further away. After interacting with the airflow entering through the inlet of the turbulence duct 2.1, the airflow gathers in the lower region of the turbulence duct 2.1, pushing the main airflow within the turbulence duct 2.1 further away (shifting upwards to cross the centerline). Thus, after passing through outlet 2.11 of the turbulence duct 2.1, the main airflow can change its output direction (the airflow output from outlet 1.11 shifts downwards).

[0048] In addition, the shifted main airflow can enter the inlet a2.21 in greater quantities, thus achieving the next cycle;

[0049] The above process is repeated cyclically, causing the airflow output from the air outlet 1.11 to repeatedly deflect in the same direction, achieving a sweeping, oscillating output airflow that provides a wind effect similar to natural wind, resulting in a better user experience.

[0050] As an improvement of this utility model, the fluid oscillator 2 includes a turbulence duct 2.1 extending in a gradually expanding structure along the center line C, a first return duct 2.2 disposed on the left side of the turbulence duct 2.1, and a second return duct 2.3 disposed on the right side of the turbulence duct 2.1;

[0051] The inlet a2.21 of the first return air duct 2.2 and the inlet b2.31 of the second return air duct 2.3 are arranged opposite to each other at the front of the outlet 2.11 of the turbulence air duct 2.1, and are respectively connected to the turbulence air duct 2.1;

[0052] The outlet aa2.22 of the first return air duct 2.2 and the outlet bb2.32 of the second return air duct 2.3 are arranged opposite to each other at the front of the inlet of the turbulence air duct 2.1 and are respectively connected to the turbulence air duct 2.1;

[0053] The inlet of the turbulence duct 2.1 is used to receive the airflow from the outlet duct 1.1, as well as the airflow returned from the first return duct 2.2 and the second return duct 2.3. The outlet 2.11 of the turbulence duct 2.1 serves as the outlet 2.11 of the fluid oscillator 2.

[0054] After the above improvements, the inlet of the turbulence duct 2.1 receives the main airflow of the outlet duct 1.1.

[0055] The main airflow may be split at the outlet 2.11 of the turbulence duct 2.1, and may enter the inlet a2.21 or the inlet b2.31;

[0056] When the inlet airflow at inlet a2.21 is greater than the inlet airflow at inlet b2.31, the airflow exits from outlet aa2.22 through the first return air duct 2.2, pushing the airflow entering the turbulence duct 2.1 further away. After interacting with the airflow entering through the inlet of the turbulence duct 2.1, the airflow gathers in the upper region of the turbulence duct 2.1, pushing the main airflow in the turbulence duct 2.1 further away (downward shifting to cross the centerline). Then, after the main airflow passes through the outlet 2.11 of the turbulence duct 2.1, which is located at the center, it can change the output direction of the airflow (the airflow output from the outlet 1.11 shifts upward).

[0057] In addition, the shifted main airflow can enter inlet b2.31 in larger quantities to achieve the next cycle;

[0058] When the airflow entering through inlet b2.31 is greater than the airflow entering through inlet a2.21, the airflow exits through outlet bb2.32 via the second return duct 2.3, pushing the airflow entering the turbulence duct 2.1 further away. After interacting with the airflow entering through the inlet of the turbulence duct 2.1, the airflow gathers in the lower region of the turbulence duct 2.1, pushing the main airflow within the turbulence duct 2.1 further away (shifting upwards to cross the centerline). Thus, after passing through outlet 2.11 of the turbulence duct 2.1, the main airflow can change its output direction (the airflow output from outlet 1.11 shifts downwards).

[0059] In addition, the shifted main airflow can enter the inlet a2.21 in greater quantities, thus achieving the next cycle;

[0060] The above process is repeated cyclically, causing the airflow output from the air outlet 1.11 to repeatedly deflect in the same direction, achieving a sweeping, oscillating output airflow that provides a wind effect similar to natural wind, resulting in a better user experience.

[0061] As an improvement of this utility model, the air outlet channel 1.1 is provided with two partitions 4 symmetrically arranged along the center line C, and two guide plates 5 arranged inside the two partitions 4 and symmetrically arranged along the center line C.

[0062] A first return air duct 2.2 is formed between the left-side baffle 4 and the guide plate 5, and a second return air duct 2.3 is formed between the right-side baffle 4 and the guide plate 5.

[0063] A turbulence duct 2.1 is formed between the two guide plates 5, and the gap formed between the two baffles 4 after their tail ends converge inward serves as the outlet 2.11 of the turbulence duct 2.1.

[0064] The inner side of the deflector 5 forms a gradually outwardly inclined deflector surface, which generates a wall adhesion effect on the passing airflow, enhances the airflow gathering effect, and can guide it to inlet a2.21 or inlet b2.31.

[0065] The baffles 4 on both sides are arranged with their tail ends converging inwards, and inlet a2.21 and inlet b2.31 are located at the front of the tail end of the baffles 4. The inner side of the tail end of the baffles 4 plays a certain role in blocking the airflow in the turbulence duct 2.1. The airflow can gather on the upper or lower side of the turbulence duct 2.1 and effectively enter into inlet a2.21 or inlet b2.31.

[0066] As an improvement of this utility model, a gap is provided between the tail end of the guide plate 5 on the left and the tail end of the partition plate 4 as the inlet a2.21, and a gap is provided between the front end of the guide plate 5 on the left and the front end of the partition plate 4 as the outlet aa2.22.

[0067] A gap is provided between the tail end of the guide plate 5 on the right and the tail end of the baffle 4 as the inlet b2.31, and a gap is provided between the front end of the guide plate 5 on the right and the front end of the baffle 4 as the outlet bb2.32.

[0068] After the above improvements, the fluid oscillator 2, formed by a relatively simple structural arrangement, has the characteristics of simple structure and reliable operation.

[0069] As an improvement of this utility model, after the front ends of the two partitions 4 converge inward, an inlet air duct 4.1 with a gradually contracting structure along the center line C is formed between them. The inlet of the inlet air duct 4.1 is used to receive the airflow of the outlet air duct 1.1, and the outlet 2.11 of the inlet air duct 4.1 is arranged opposite to the inlet of the turbulence air duct 2.1.

[0070] After the above improvements, the inlet air duct 4.1 is designed with a gradually decreasing size from the front end to the rear end, which facilitates the entry of airflow. The outlet 2.11 of the inlet air duct 4.1 is set opposite to the inlet of the turbulence air duct 2.1. The main airflow formed after the airflow is gathered and pressurized in the inlet air duct 4.1 can continuously and efficiently enter the turbulence air duct 2.1, making the output oscillating airflow more continuous.

[0071] As an improvement of this utility model, the air outlet channel 1.1 is further provided with a first air duct 6 on the left side of the first return air duct 2.2 and a second air duct 7 on the right side of the second return air duct 2.3;

[0072] The first air duct 6 is used to receive the airflow from the air outlet duct 1.1 and to discharge air from the air outlet 1.11 in a first direction.

[0073] The second air duct 7 is used to receive the airflow from the air outlet duct 1.1 and to discharge air from the air outlet 1.11 in a second direction, wherein the first direction and the second direction are intersected.

[0074] The first direction can be configured to be downward and the second direction can be configured to be upward. When the airflow enters the first air duct 6, it can output the airflow downward and when the airflow enters the second air duct 7, it can output the airflow upward. If the flow rate and wind force of the two airflows are relatively consistent, they can output the airflow forward after converging.

[0075] If one of the airflows has a smaller flow rate and wind force, it will tend to output airflow in the direction with a larger wind force and flow rate after converging.

[0076] As an improvement of this utility model, the inlet of the first air duct 6 and the inlet of the second air duct 7 are located in the same plane as the inlet of the converging air duct 4.1;

[0077] A first connecting shaft 9 is provided between the inlet of the first air duct 6 and the inlet of the converging air duct 4.1. A first air duct damper 6.1 and a converging air duct damper a4.11 are rotatably connected to the first connecting shaft 9. The rotation of the first air duct damper 6.1 is used to adjust the opening of the inlet of the first air duct 6. The first air duct damper 6.1 and the converging air duct damper a4.11 can be respectively connected to a motor or an actuator to drive the first air duct damper 6.1 and the converging air duct damper a4.11 to rotate independently.

[0078] The intake damper a4.11 is rotated to adjust the opening of the upper part of the intake duct 4.1;

[0079] A second connecting shaft 10 is provided between the inlet of the second air duct 7 and the inlet of the converging air duct 4.1. A second air duct damper 7.1 and a converging air duct damper b4.12 are rotatably mounted on the second connecting shaft 10. The rotation of the second air duct damper 7.1 is used to adjust the opening of the inlet of the second air duct 7, and the rotation of the converging air duct damper b4.12 is used to adjust the opening of the lower half of the inlet of the converging air duct 4.1. The second air duct damper 7.1 and the converging air duct damper b4.12 can be respectively connected to a motor or an actuator to drive the second air duct damper 7.1 and the converging air duct damper b4.12 to rotate independently.

[0080] After the above improvements, the inlet of the first air duct 6 and the inlet of the second air duct 7 are opened, and the inlet of the converging air duct 4.1 is closed, so that the airflow discharged from the first air duct 6 and the second air duct 7 can be horizontally output after converging. Of course, the opening of the inlet of the first air duct 6 or the opening of the inlet of the second air duct 7 can also be adjusted to make the airflow tend to be output in the direction of greater wind force and flow rate after converging.

[0081] Alternatively, the inlet of the first air duct 6 can be opened, the inlet of the second air duct 7 can be closed, and the inlet of the converging air duct 4.1 can be closed, so as to realize the output airflow in the first direction, and the rotation of the first air duct damper 6.1 can be controlled to adjust the opening and control the size of the airflow output by the first air duct 6;

[0082] Alternatively, the inlet of the first air duct 6 is closed, the inlet of the second air duct 7 is open, and the inlet of the converging air duct 4.1 is closed, so as to realize the output airflow in the second direction. Furthermore, the rotation of the second air duct damper 7.1 can be controlled to adjust the opening and control the size of the airflow output from the second air duct 7.

[0083] Alternatively, the inlet of the first air duct 6 is closed, the inlet of the second air duct 7 is closed, and the inlet of the converging air duct 4.1 is opened to achieve oscillating sweeping airflow. The rotation of the converging air duct damper a4.11 and the converging air duct damper b4.12 can be controlled to control the size of the output airflow.

[0084] As an improvement of this utility model, left and right guide vane groups are respectively provided in the first air duct 6 and the second air duct 7. The left and right guide vane groups include several linked left and right guide vanes that can rotate left and right. The left and right guide vanes rotate to adjust the left and right output direction of the airflow.

[0085] After the above improvements, the left and right directions of the output airflow can be adjusted by rotating the left and right guide vanes, which enriches the functionality of the device and improves the user experience.

[0086] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
