Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning vent technology, and in particular to a rotatable and adjustable automotive air conditioning vent structure. Background Technology

[0002] The air conditioning vents are a component of the car's air conditioning system. Their main function is to regulate the air volume and direction to achieve the requirements of air circulation and temperature control inside the vehicle, providing a comfortable in-vehicle environment for drivers and passengers.

[0003] In related technologies, please refer to Chinese utility model patent with authorization announcement number CN222921345U, which discloses a quick-adjustment air outlet for an automotive air conditioner, including a base, a housing, a vertical airflow adjustment mechanism and a horizontal airflow adjustment mechanism. The horizontal blades directly control the vertical airflow, and the paddle is used to manually adjust the blade angle for easy and quick change of airflow direction. The first rotating rod serves as the shaft connecting the horizontal blades and supports the overall synchronous adjustment of the blades. The bearing ensures the smooth rotation of the rotating rod and its long-term durability.

[0004] When the temperature inside the car remains constant, the airflow is blown out from the gaps between the blades. Although the overall airflow angle can be adjusted, the airflow from the gaps between the blades is still blowing directly. This not only results in low air circulation efficiency inside the car, but also reduces the comfort of passengers and has an adverse effect on their health if the airflow is blown directly for a long time. Utility Model Content

[0005] In order to improve the efficiency of air circulation in the vehicle and enhance the comfort of passengers, this utility model provides a rotatable and adjustable automotive air conditioning vent structure.

[0006] The rotatable and adjustable automotive air conditioning vent structure provided in this application adopts the following technical solution:

[0007] A rotatable and adjustable automotive air conditioning vent structure includes a duct and fixed fan blades disposed within the duct. The inner end of the duct is connected to the air duct of the automotive air conditioning system, and the outer end of the duct is an air outlet facing the interior space of the vehicle. A mounting post is coaxially fixed within the duct. Multiple fixed fan blades are arranged in a circumferential array around the axis of the mounting post, and the end of each fixed fan blade away from the mounting post is fixedly connected to the inner wall of the duct. The fixed fan blades extend inward at an angle, and an air supply gap is formed between two adjacent fixed fan blades. An adjustment mechanism for adjusting the airflow is provided within the duct.

[0008] By adopting the above technical solution, the air volume in the air duct is guided by the fixed fan blades after passing through the air duct and then blown into the vehicle interior space from the air supply gap. Since the fixed fan blades are arranged in a circumferential array along the axis of the mounting column, i.e., radially distributed and extended in an inclined state, the airflow will form a jet along the inclined surface of the fixed fan blades under the guidance of the fixed fan blades. The air supply in the entire air duct generates vortices under the action of multiple jets. A negative pressure zone is formed in the central area of ​​the vortex, which induces the air at the air outlet to mix quickly with the supply air, thereby improving the air circulation efficiency in the vehicle. In addition, the direct airflow can be reduced by the adjustment mechanism, thereby improving the ride comfort of the driver and passengers.

[0009] Optionally, the adjustment mechanism includes:

[0010] The movable fan blades are provided in multiples and correspond one-to-one with the fixed fan blades. The movable fan blades are slidably mounted on the mounting column via the mounting assembly and are used to adjust the air outlet angle. In the initial state, the movable fan blades are located below the corresponding fixed fan blades.

[0011] A drive assembly, which is mounted on a mounting column and is used to drive the movable fan blades to move.

[0012] By adopting the above technical solution, in the initial state, the movable fan blades are located one-to-one below the corresponding fixed fan blades. When it is necessary to adjust the air outlet angle, the drive component is activated to move the movable fan blades within the air supply gap, thereby diverting and guiding the airflow, further reducing the amount of direct airflow, and improving the air circulation efficiency in the vehicle while improving the ride comfort of the driver and passengers.

[0013] Optionally, the mounting column has a sliding space, and the mounting assembly includes:

[0014] A movable column is slidably disposed within a sliding space, and the driving component is connected to the movable column via a connecting component and is used to drive the movable column to rise and fall.

[0015] The mounting rods are provided in multiples, each corresponding to a movable fan blade. The multiple mounting rods are arranged in a circumferential array around the axis of the movable column and extend radially on the outer surface of the movable column. The air supply gap is provided with a guide groove for guiding the mounting rods. The guide groove is connected to the sliding space. The mounting rods pass through the corresponding guide grooves. The movable fan blades are fixed on the mounting rods that extend out of the guide grooves and extend inward at an angle. The lifting and lowering of the movable column drives the movable fan blades to block the air supply gap.

[0016] By adopting the above technical solution, in the initial state, the movable fan blade is located below the fixed fan blade. The drive component starts and drives the movable column to move upward through the connecting component. The movable column drives the movable fan blade to move upward. At the same time, the guide groove limits and guides the movement of the mounting rod, so that the movable fan blade moves into the air supply gap and diverts and guides the direct airflow, thereby reducing the direct airflow.

[0017] Optionally, the inner end of the guide groove is located below the fixed fan blade, and the outer end of the guide groove is located above the blade of the adjacent fixed fan blade.

[0018] By adopting the above technical solution, in the initial state, the mounting rod is located at the inner end of the guide groove. As the movable column moves upward, the mounting rod moves from the inner end to the outer end of the guide groove, and the movable fan blade moves into the air supply gap. The airflow blowing directly from the air supply gap is blocked and diverted by the movable fan blade. Then the airflow is blown out through the gap between the movable fan blade and the fixed fan blade, thereby reducing the amount of air blowing directly and improving human comfort. At the same time, the principle of airflow guidance by the movable fan blade is the same as that of the fixed fan blade, thereby improving the air circulation efficiency inside the vehicle.

[0019] Optionally, the connection component includes:

[0020] A connecting chassis is provided within a sliding space, and an outwardly extending connecting shaft is coaxially fixed on the connecting chassis.

[0021] A connecting top plate is coaxially fixed to a connecting shaft and is positioned opposite to a connecting base plate, and a movable column is coaxially sleeved on the connecting shaft.

[0022] Optionally, the driving component includes:

[0023] A spring is provided on the bottom wall of the sliding space and is fixedly connected to the connecting chassis. When the movable fan blade is located below the fixed fan blade, the spring is in a compressed state.

[0024] The drive column is coaxially rotatably disposed within the sliding space. The inner end of the drive column abuts against the connecting top plate and the outer end extends out of the sliding space. The outer surface of the drive column has a threaded section, which is threadedly engaged with the inner wall of the mounting column.

[0025] By adopting the above technical solution, in the initial state, the spring is compressed, the movable fan blade is located below the fixed fan blade, and the drive column is rotated outward. The spring rebounds and pushes the connecting chassis to move. The connecting chassis pushes the movable column to move. Under the limit of the guide groove, the mounting rod moves from the inner end of the guide groove to the outer end. As the mounting rod moves, the movable column rotates on the connecting shaft. The position of the connecting chassis and the connecting top plate is limited by the cooperation of the spring and the threaded section of the drive column. When returning, the drive column can be rotated in the opposite direction. The air outlet angle can be adjusted by rotating the drive column. It can be adjusted according to the needs of the driver and passengers, thereby improving the ride comfort and the convenience of adjusting the air outlet angle of the car air conditioning vent.

[0026] Optionally, the outer end of the drive column extending out of the sliding space is provided with a knob that is easy to rotate, and the knob has anti-slip texture.

[0027] By adopting the above technical solution, the knob and anti-slip texture increase the convenience of rotating the drive column.

[0028] Optionally, the outer surface of the connecting top plate has a drive groove adapted to the inner end of the drive column.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] 1. After passing through the air duct, the airflow is guided by the fixed fan blades and blown into the vehicle interior from the air supply gap. Since the fixed fan blades are arranged in a radial array along the axis of the mounting column and extend in an inclined state, the airflow will form a jet along the inclined surface of the fixed fan blades under the guidance of the fixed fan blades. The air supply in the entire air duct generates vortices under the action of multiple jets. The central area of ​​the vortex forms a negative pressure zone, which induces the air at the air outlet to mix quickly with the supply air, thereby improving the air circulation efficiency inside the vehicle.

[0031] 2. In the initial state, the movable fan blades are located one-to-one below the corresponding fixed fan blades. When the air outlet angle needs to be adjusted, the drive component is activated to move the movable fan blades within the air supply gap, thereby diverting and guiding the airflow, further reducing the amount of air blown directly, and improving the air circulation efficiency in the vehicle while enhancing the ride comfort of the driver and passengers.

[0032] 3. The position of the connection between the chassis and the top plate is limited by the cooperation of the spring and the threaded section of the drive column. When retracting, the drive column can be rotated in the opposite direction. The air outlet angle can be adjusted by rotating the drive column. It can be adjusted according to the needs of the driver and passengers, thereby improving the ride comfort and the convenience of adjusting the air outlet angle of the car air conditioning vent.

[0040] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0041] This application discloses a rotatable and adjustable automotive air conditioning vent structure.

[0042] Reference Figure 1 and Figure 2 A rotatable and adjustable automotive air conditioning vent structure includes a duct 1 and fixed fan blades 11 disposed inside the duct 1. The inner end of the duct 1 is connected to the air duct of the automotive air conditioning system, and the outer end of the duct 1 is the air outlet facing the interior space of the vehicle. A mounting post 2 is coaxially fixed inside the duct 1. Multiple fixed fan blades 11 are provided, and the multiple fixed fan blades 11 are arranged in a circumferential array around the axis of the mounting post 2. The end of the fixed fan blade 11 away from the mounting post 2 is fixedly connected to the inner wall of the duct 1. The fixed fan blades 11 extend inward at an angle, and an air supply gap 12 is formed between two adjacent fixed fan blades 11. An adjustment mechanism 3 for adjusting the air outlet is provided inside the duct 1.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The fixed fan blade 11 has a fan-shaped structure, and the width of the blade near the mounting column 2 is smaller than the width of the blade away from the mounting column 2. There is no obstruction between two adjacent fixed fan blades 11.

[0044] Reference Figure 1 , Figure 2 and Figure 3 An installation plate 13 is fixed on the inner wall of the air duct 1 at the end away from the air outlet, and the installation column 2 is fixed on the installation plate 13 and extends toward the air outlet.

[0045] Reference Figure 1 , Figure 2 and Figure 3 The adjustment mechanism 3 includes a movable fan blade 31 and a drive assembly 32. Multiple movable fan blades 31 are provided and correspond one-to-one with fixed fan blades 11. The movable fan blades 31 are slidably mounted on the mounting column 2 through the mounting assembly 4 and are used to adjust the air outlet angle. The mounting column 2 has a sliding space 21 that passes through both ends of the mounting column 2. The mounting assembly 4 includes a movable column 41 and a mounting rod 42.

[0046] Reference Figure 2 , Figure 3 and Figure 4 The movable column 41 is slidably disposed within the sliding space 21. Multiple mounting rods 42 are provided and correspond one-to-one with the movable fan blades 31. The multiple mounting rods 42 are arranged in a circumferential array around the axis of the movable column 41 on the outer surface of the movable column 41 and extend radially. Each air supply gap 12 is provided with a guide groove 14 for guiding the mounting rod 42. The guide groove 14 is connected to the sliding space 21 and corresponds one-to-one with the mounting rod 42. The mounting rod 42 passes through the corresponding guide groove 14. The movable fan blades 31 are fixed on the mounting rods 42 that extend out of the guide grooves 14 and extend inward at an angle. The size and tilt state of the movable fan blades 31 are consistent with those of the fixed fan blades 11.

[0047] Reference Figure 2 and Figure 3 The inner end of the guide groove 14 is located below the fixed fan blade 11, and the outer end of the guide groove 14 is located above the blades of the adjacent fixed fan blade 11. The drive assembly 32 is mounted on the mounting column 2 and is used to drive the movable fan blade 31 to move. The drive assembly 32 is connected to the movable column 41 through the connecting assembly 5 and is used to drive the movable column 41 to rise and fall. Here, rising and falling refers to the movable column 41 moving inward and outward within the sliding space 21. When the movable column 41 rises and falls, the movable fan blade 31 is moved by the mounting rod 42 and blocks the air supply gap 12. In the initial state, the movable fan blade 31 is located below the corresponding fixed fan blade 11. The end of the mounting rod 42 near the guide groove 14 is located directly below the fixed fan blade 11, and the end of the mounting rod 42 away from the guide groove 14 is located between two adjacent fixed fan blades 11. When the mounting rod 42 is located at the outer end of the guide groove 14, the movable fan blade 31 partially blocks the end of the adjacent fixed fan blade 11 near the mounting column 2.

[0048] Reference Figure 2 , Figure 3 and Figure 4 The connecting assembly 5 includes a connecting base 51 and a connecting top plate 52. The connecting base 51 is coaxially disposed within the sliding space 21. A connecting shaft 53 extending outward is coaxially fixed on the connecting base 51. The connecting top plate 52 is coaxially fixed to the connecting shaft 53 and is disposed opposite to the connecting base 51. The movable column 41 is coaxially sleeved on the connecting shaft 53 and can rotate around the axis of the connecting shaft 53. The connecting base 51 and the connecting top plate 52 cooperate to limit the two ends of the movable column 41.

[0049] Reference Figure 2 , Figure 3 and Figure 4 The drive assembly 32 includes a spring 321 and a drive column 322. The portion of the mounting plate 13 located inside the mounting column 2 is the inner bottom wall of the sliding space 21. One end of the spring 321 is fixed to the inner bottom wall of the sliding space 21, and the other end of the spring 321 extends outward and is fixed to the connecting chassis 51. When the movable fan blade 31 is located below the fixed fan blade 11, the spring 321 is in a compressed state.

[0050] Reference Figure 2 , Figure 3 and Figure 4 The drive column 322 is coaxially rotatably disposed within the sliding space 21. The inner end of the drive column 322 abuts against the connecting top plate 52 and the outer end extends out of the sliding space 21. The outer surface of the connecting top plate 52 has a drive groove 54 adapted to the inner end of the drive column 322. The inner end of the drive column 322 abuts against the drive groove 54. The inner diameter of the drive groove 54 is slightly larger than the outer diameter of the inner end of the drive column 322 so that the inner end of the drive column 322 can rotate within the drive groove 54. The outer surface of the drive column 322 has a threaded section 323. The inner wall of the mounting column 2 near the air outlet has an internal thread, and the threaded section 323 is threadedly engaged with the internal thread.

[0051] Reference Figure 2 , Figure 3 and Figure 4 The drive column 322 extends out of the sliding space 21 and is coaxially fixed with a knob 33 for easy rotation. The knob 33 has anti-slip texture.

[0052] Reference Figure 2 , Figure 3 and Figure 5In the initial state, the spring 321 is in a compressed state, and the mounting rod 42 is located at the inner end of the guide groove 14. At this time, the air in the air duct blows towards the fixed fan blade 11 after passing through the air duct 1. Since the fixed fan blade 11 is arranged in a circumferential array along the axis of the mounting column 2, i.e., radially distributed and extended in an inclined state, the airflow will form a jet along the inclined surface of the fixed fan blade 11 under the guidance of the fixed fan blade 11. The air supply in the entire air duct 1 generates a vortex under the action of multiple jets. The central area of ​​the vortex forms a negative pressure zone, which induces the air at the air outlet to mix quickly with the supply air, thereby improving the air circulation efficiency in the vehicle. At this time, the air volume that is not blocked and diverted by the fixed fan blade 11 can be blown directly into the vehicle space from the air supply gap 12.

[0053] Reference Figure 3 , Figure 4 and Figure 6 When it is necessary to reduce the direct airflow, turn the knob 33 to drive the drive column 322 to rotate. The drive column 322 moves outward, the spring 321 returns to its deformation and pushes the connecting chassis 51 to move outward as a whole, thereby driving the movable column 41 to move outward. The movable column 41 drives the mounting rod 42 to move. Due to the limit of the guide groove 14, the mounting column 2 moves outward and rotates on the rotating shaft. As the mounting column 2 moves, the movable fan blade 31 gradually blocks the direct airflow in the air supply gap 12. The airflow passes through the gap between the movable fan blade 31 and the fixed fan blade 11 and blows out, thereby reducing the direct airflow and improving human comfort. At the same time, the principle of the movable fan blade 31 in guiding the airflow is the same as that of the fixed fan blade 11, thereby improving the air circulation efficiency in the vehicle.

[0054] Reference Figure 3 and Figure 4 When a reversal is needed, simply rotate knob 33 in the opposite direction. The position of connecting chassis 51 and connecting top plate 52 is limited by the cooperation of spring 321 and threaded section 323 of drive column 322. By rotating drive column 322, the air outlet angle can be adjusted according to the needs of the driver and passengers, thereby improving the ride comfort and the convenience of adjusting the air outlet angle of the car air conditioning vent.

[0055] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
