[0002] Since automobiles require air ducts for ventilation and temperature regulation during operation, optimizing the airflow distribution performance of these ducts is crucial for improving in-vehicle comfort. However, existing automotive air ducts often suffer from uneven airflow distribution in practical use, resulting in suboptimal ventilation or heating / cooling effects in certain areas. Therefore, when designing automotive air ducts, internal structures are typically added to improve airflow guidance. A common improvement method involves adjusting airflow direction through complex internal structures, but this approach can increase manufacturing difficulty and cost in practical applications, while also limiting its effectiveness in guiding airflow. Therefore, this invention improves upon automotive air ducts with airflow guide vanes to more efficiently optimize airflow distribution and enhance in-vehicle comfort. Utility Model Content

[0019] This utility model provides an automotive air duct with airflow guide vanes, the specific structure and working principle of which are described in conjunction with the attached diagram. Figure 1 To be continued Figure 3Detailed description follows. The main body of the air duct 1 is a rectangular tubular structure with an air inlet 2 at the top and multiple air outlets 3 at the bottom, used to distribute the airflow entering the air duct to different areas inside the vehicle. A guide plate 4 is fixedly installed inside the main body of the air duct 1. An arc-shaped guide groove 12 is formed on the surface of the guide plate 4, and an airflow guide plate 5 is slidably installed inside the guide groove 12. The edge of the airflow guide plate 5 has a wavy structure, and a connecting shaft 6 is symmetrically fixed on both sides. The outer end of the connecting shaft 6 is rotatably installed on the inner wall of the main body of the air duct 1. An adjustment knob 7 is fixed on one outer wall of the main body of the air duct 1. A transmission rod 8 is fixed inside the adjustment knob 7, and a gear 9 is fixed on the other end of the transmission rod 8. The outer circumference of the gear 9 meshes with a rack 10, and both ends of the rack 10 are fixed to the connecting shaft 6 of the airflow guide plate 5. A limiting block is fixed on the inner wall of the main body of the air duct 1. An arc-shaped limiting groove 11 is formed on the surface of the limiting block, and the connecting shaft 6 of the airflow guide plate 5 is slidably installed inside the limiting groove 11.

[0020] An elastic support is fixed to the inner wall of the duct body 1. One end of the elastic support is fixedly connected to the bottom of the guide plate 4, and the other end is fixed to the inner wall of the duct body 1. A buffer pad is fixed in the middle, and multiple through holes are opened on the surface of the buffer pad. A filter screen is fixed inside the through holes, and the surface of the filter screen is coated with an antibacterial coating. A positioning block is fixed to the top of the elastic support. An arc-shaped positioning groove is opened on the surface of the positioning block, and the connecting shaft 6 of the airflow guide plate 5 is slidably installed inside the positioning groove. Multiple guide holes 13 are opened on the surface of the guide plate 4. A guide ring is fixed inside the guide hole 13. A spiral blade is fixed on the inner wall of the guide ring, and multiple micropores are opened on the surface of the spiral blade. A flow divider block 14 is fixed to the bottom of the guide plate 4. Multiple flow divider grooves 15 are opened on the surface of the flow divider block 14. A flow divider plate 16 is fixed inside the flow divider groove 15. An arc-shaped flow divider hole is opened on the surface of the flow divider plate 16. A support column is fixed to the bottom of the flow divider block 14. A spring is fixed to the outer wall of the support column, and one end of the spring is fixedly connected to the inner wall of the duct body 1.

[0021] In actual use, when outside air enters the main body of the air duct 1 through the air inlet 2, the airflow first passes through the guide groove 12 on the surface of the guide plate 4. The arc-shaped structure of the guide groove 12 guides the airflow along a specific path. The guide holes 13 on the guide plate 4 further change the airflow direction. The guide ring inside the guide hole 13 generates a rotational effect on the airflow through the spiral blades, thereby optimizing the airflow distribution. The airflow then reaches the splitter block 14. The splitter groove 15 on the surface of the splitter block 14 cooperates with the splitter plate 16 to divide the airflow into multiple streams. Each stream of airflow is discharged through the arc-shaped splitter hole on the surface of the splitter plate 16, reducing airflow resistance and improving flow efficiency. The support column at the bottom of the splitter block 14 provides elastic support through springs, ensuring that the splitter block 14 remains stable under the impact of airflow.

[0022] Users can adjust the angle of the airflow guide plate 5 by rotating the adjustment knob 7. When the adjustment knob 7 is rotated, it drives the transmission rod 8 to rotate, and the gear 9 fixed at the other end of the transmission rod 8 rotates accordingly. The gear 9 meshes with the rack 10, and the rack 10 moves in a straight line, pushing the connecting shaft 6 of the airflow guide plate 5 to slide along the arc-shaped trajectory of the limiting groove 11. The sliding of the connecting shaft 6 changes the angle of the airflow guide plate 5, thereby changing the flow direction of the airflow in the main body of the air duct 1. The wavy edge structure of the airflow guide plate 5 increases the airflow disturbance effect, making the airflow distribution more uniform. The arc-shaped design of the limiting groove 11 and the positioning groove ensures that the connecting shaft 6 slides smoothly, avoiding the airflow guide plate 5 from shifting or getting stuck due to angle adjustment.

[0023] The design of the elastic support component not only provides support for the air deflector 4, but also effectively filters impurities in the airflow through the combination of a buffer pad and a filter screen. The perforations on the surface of the buffer pad allow airflow to pass smoothly, while the filter screen intercepts dust particles and other impurities carried in the airflow. The antibacterial coating on the surface of the filter screen inhibits bacterial growth, improving the air quality inside the vehicle. The buffer pad in the middle of the elastic support component acts as a shock absorber under airflow impact, reducing the impact of airflow vibration on the main body of the air duct 1.

[0024] This invention achieves uniform distribution and flexible adjustment of airflow within the main body 1 of the air duct through the aforementioned structure. After entering through the air inlet 2, the airflow is guided and distributed step-by-step by the guide plate 4, guide groove 12, guide hole 13, and diverter block 14, and finally discharged through multiple air outlets 3. The angle adjustment function of the airflow guide plate 5 allows for adjustment of the airflow direction according to actual needs, meeting the ventilation and temperature regulation requirements of different scenarios. The combined design of the elastic support and filter further enhances the practicality and hygiene performance of the device, ensuring a comfortable and healthy environment inside the vehicle.

[0025] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principles of this utility model are further explained below in conjunction with specific application scenarios.

[0026] First, when outside air enters the main body of the air duct 1 through the air inlet 2, the airflow passes through the guide grooves 12 on the surface of the guide plate 4. The arc-shaped structure of the guide grooves 12 effectively guides the airflow along a specific path, thus avoiding turbulence within the air duct. Then, the guide holes 13 on the guide plate 4 further change the airflow direction. The guide rings inside the guide holes 13, through the action of the spiral blades, cause the airflow to rotate. This rotational effect not only optimizes the airflow distribution but also reduces the resistance of the airflow within the guide holes 13, thereby improving the airflow efficiency. Multiple micro-holes on the surface of the spiral blades further refine the airflow, distributing it more evenly throughout the various areas of the main body of the air duct 1.

[0027] Subsequently, the airflow reaches the diverter block 14, where the diverting grooves 15 on the surface of the diverter block 14 cooperate with the diverter plate 16 to divide the airflow into multiple streams. Each stream of airflow is discharged through the arc-shaped diverting holes on the surface of the diverter plate 16. The arc-shaped diverting holes reduce airflow resistance and ensure that the airflow flows more efficiently. The support column at the bottom of the diverter block 14 provides elastic support through springs, ensuring that the diverter block 14 remains stable under the impact of airflow. This elastic support design effectively alleviates the vibration problem caused by airflow impact and also prevents the diverter block 14 from shifting its position due to long-term use.

[0028] In actual operation, the user can adjust the angle of the airflow guide plate 5 by rotating the adjustment knob 7. When the adjustment knob 7 is rotated, the transmission rod 8 fixed at its inner end rotates accordingly, and the gear 9 fixed at the other end of the transmission rod 8 rotates accordingly. The gear 9 meshes with the rack 10, and the rack 10 moves in a straight line, pushing the connecting shaft 6 of the airflow guide plate 5 to slide along the arc-shaped trajectory of the limiting groove 11. The sliding of the connecting shaft 6 changes the angle of the airflow guide plate 5, thereby changing the flow direction of the airflow in the air duct body 1. The wavy edge structure of the airflow guide plate 5 increases the turbulence effect of the airflow, making the airflow distribution more uniform. The arc-shaped design of the limiting groove 11 and the positioning groove ensures that the connecting shaft 6 slides smoothly, avoiding the airflow guide plate 5 from shifting or getting stuck due to angle adjustment.

[0029] Furthermore, the design of the elastic support not only provides support for the air deflector 4, but also effectively filters impurities in the airflow through the combination of a buffer pad and a filter screen. Multiple through-holes on the surface of the buffer pad allow airflow to pass smoothly, while the filter screen intercepts dust particles and other impurities carried in the airflow. The antibacterial coating on the filter screen surface inhibits bacterial growth, thereby improving the air quality inside the vehicle. The buffer pad in the middle of the elastic support acts as a shock absorber under airflow impact, reducing the impact of airflow vibration on the main body of the air duct 1 and ensuring the stability of the air duct during long-term use.

[0030] Through the above steps, this invention achieves the step-by-step guidance and distribution of airflow within the main body 1 of the air duct. After entering through the air inlet 2, the airflow undergoes multiple actions from the guide plate 4, guide groove 12, guide hole 13, and diverter block 14, and is finally discharged through multiple air outlets 3. The angle adjustment function of the airflow guide plate 5 allows for flexible adjustment of the airflow direction according to actual needs, meeting the ventilation and temperature regulation requirements of different scenarios. The combined design of the elastic support and filter further enhances the practicality and hygiene performance of the device, ensuring a comfortable and healthy environment inside the vehicle.
