Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically to a multi-layer plate airflow direction adjustment mechanism for automotive air conditioning vents. Background Technology

[0002] Inside a car, the air vents play a crucial role in the comfort experience of the driver and passengers.

[0003] Existing air outlet devices have air guide components (usually air guide blades) installed in the air outlet channel, which adjust the output direction of the airflow when they swing. Each layer has multiple air guide blades, which are connected in series by a linkage structure. To achieve the desired air guiding effect, the air guide blades need to be relatively long. Therefore, the air outlet channel needs a certain depth to accommodate the installation of the air guide vanes, but this results in the overall structure of the air outlet device being less compact and requiring a larger volume within the limited space of a car, making it difficult to meet the stringent requirements of modern cars for space optimization.

The transmission groove on the rear air guide plate is independently matched with the transmission pin with a large rotation radius; Among them, the transmission pin with a large rotation radius has a relatively large tangential displacement and drives the air guide plate to have a large displacement, while the transmission pin with a small rotation radius has a relatively small tangential displacement and drives the air guide plate to have a small displacement.

[0010] As an improvement of this utility model, the air guide plate is provided with a rearwardly extending connecting part, and the transmission groove is provided on the connecting part.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Please see Figure 1-5 , Figure 11 As shown, A multi-layer plate airflow direction adjustment mechanism for an automotive air conditioning vent includes: an vent housing 1, which internally defines an air outlet channel 1.1 extending along a first direction E, and air guide vanes 6 and air guide plates 2 are sequentially arranged in the air outlet channel 1.1 along the first direction E. The guide vanes 6 are multiple and are arranged vertically at intervals within the air outlet duct 1.1. They are interconnected by a linkage structure. The guide vanes 6 are designed to swing up and down to adjust the vertical air outlet angle of the output airflow. There are at least two air guide plates 2, which are stacked in the front-to-back direction. The air guide plates 2 are arranged to be able to move left and right. Each air guide plate 2 has several air guide holes 2.1. The air guide holes 2.1 adjacent to each other in the initial state are aligned to form an airflow channel extending in the front and back. The airflow channel is connected to the air outlet channel 1.1. It also includes a drive component, which is used to make at least one air guide plate 2 translate left and right relative to the adjacent air guide plate 2, change the relative position of the front and rear adjacent air guide holes 2.1, and thus make the airflow channel bend left and right to adjust the left and right air outlet angle of the output airflow.

[0030] At least one air guide plate 2 moves left or right relative to the adjacent air guide plate 2, thereby causing a relative offset between the air guide holes 2.1 of the adjacent air guide plates 2. The airflow channel can bend left or right. When the airflow passes through the air guide channel, it is guided and output according to the direction after the angle change.

[0031] This application achieves left and right launch angle adjustment through the air guide plate 2. Compared with the traditional solution of swinging blades left and right, the air guide plate 2 of this application is thinner in the front and back direction, occupies less installation area, and the front and back depth of the air outlet channel 1.1 is shallow enough to meet the installation. The entire air outlet device is more compact and suitable for use in cars with limited space. In addition, the air guide plate 2 does not require linkage structure to achieve linkage, which effectively reduces costs.

[0032] As an improvement of this utility model, the drive component includes a rotating disk 3 located behind the air guide plate 2, which makes the structural layout more reasonable and the space utilization rate higher. Rotary disk 3 is driven by actuator 7 to rotate left and right along axis E. A transmission pin 3.1 is provided on the rotating disk 3, and the transmission pin 3.1 is arranged parallel to the axis E. A transmission groove extending forward and backward is provided on the air guide plate 2, and the transmission pin 3.1 enters into the transmission groove. The axis F of the rotating disk 3, the vertical center line of the air guide plate 2, and the mating center line of the transmission pin 3.1 and the drive groove 2.21 are all located in the same plane. The transmission force applied by the transmission pin 3.1 to the drive groove 2.21 is distributed along the vertical center line of the air guide plate 2. When the rotating disk 3 rotates, the transmission pin 3.1 and the transmission groove cooperate to drive the air guide plate 2 to move left and right under the guidance of the guide structure; this enables the air guide plate 2 to move left and right more stably, thereby enabling the air guide channel to form a bending effect effectively and reliably to guide the airflow.

[0033] Please see Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, A number of transmission pins 3.1 are arranged sequentially from front to back along the same radial direction perpendicular to axis E on the rotating disk 3, and the rotation radius of the transmission pins 3.1 is set in an arithmetic decreasing trend from front to back. The number of air guide plates 2 is equal to that of the transmission pins 3.1, and each air guide plate 2 has a transmission groove. Adjacent air guide plates 2, wherein the transmission groove on the front air guide plate 2 is independently engaged with the transmission pin 3.1 with a small rotation radius. The transmission groove on the rear air guide plate 2 is independently engaged with the transmission pin 3.1 with a large rotation radius; Among them, the transmission pin 3.1 with a large rotation radius has a relatively large tangential displacement and drives the air guide plate 2 to have a large displacement, while the transmission pin 3.1 with a small rotation radius has a relatively small tangential displacement and drives the air guide plate 2 to have a small displacement.

[0034] Multiple air guide vanes 2 are driven by the same rotating disk 3 to move left and right, which makes the structure more compact and reduces costs. The displacement of the multiple air guide plates 2 gradually increases from front to back, thereby obtaining a guide channel with a larger bending range, which can greatly adjust the left and right air outlet angles and obtain a better air outlet angle adjustment effect.

[0035] The air guide plate 2 is provided with a rearwardly extending connecting part 2.2, and the transmission groove is provided on the connecting part 2.2.

[0036] After the above improvements, the connection position of the drive groove 2.21 and the transmission pin 3.1 is arranged on the connection part 2.2 behind the air guide plate 2, which does not occupy the area of ​​the air guide plate 2, and the air guide plate 2 as a whole can be made thinner; Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, in some embodiments, there are two rotating disks 3, which are arranged coaxially at intervals and are kept rotating synchronously by a linkage 3.2. The air guide plate 2 is provided with connecting parts 2.2 at its upper and lower ends, and the two connecting parts 2.2 correspond to the transmission pins 3.1 on the two rotating disks 3, and are provided with driving grooves 2.21 that cooperate independently with them. The rotating disks 3 are driven by the cooperation structure of the two sets of transmission pins 3.1 and driving grooves 2.21 to move the air guide plate 2 left and right.

[0037] The two rotating disks 3 move synchronously and drive the air guide plate 2 to translate through the cooperation structure of the transmission pin 3.1 and the drive groove 2.21 respectively. Without adding a motor, the load capacity is greater, the risk of sliding resistance is reduced, and the translation of the air guide plate 2 is stable and reliable.

[0038] In some embodiments, the connecting portions 2.2 of each air guide plate 2 are stacked in a direction parallel to the axis F, and the air outlet housing 1 outside the air outlet channel 1.1 is provided with a receiving cavity to accommodate the connecting portion 2.2, so that the connecting portion 2.2 does not encroach on the air outlet channel 1.1 and does not affect the passage of airflow.

[0039] Please see Figure 9 , Figure 10 As shown, a decorative panel 4 is connected to the air outlet housing 1, and an assembly space 4.1 is formed between the decorative panel 4 and the air outlet housing 1. The air guide plate 2 is set in the assembly space 4.1. The air guide plate 2 can be covered by the decorative panel 4, and the decorative panel is within the occupant's field of vision, which can obtain a better visual effect.

[0040] Each air guide plate 2 has an extension 2.3 at its upper or lower end. Adjacent extensions 2.3 are stacked one after the other. The guiding structure includes a slider 2.31 and a groove 2.32 disposed between the front and rear end faces of adjacent extensions 2.3. The slider 2.31 and the groove 2.32 are interlocked. When adjacent air guide plates 2 move left and right, they are guided by the cooperation structure of the slider 2.31 and the groove 2.32. The guide structure also includes a first guide portion 2.33 provided in the extension 2.3 at the rear position, and the air outlet housing 1 is provided with a first guide groove 1.2 extending in the left and right direction, and the first guide portion 2.33 is embedded in the first guide groove 1.2; The guide structure also includes a second guide groove 2.34 provided in the extension 2.3 at the front position. The second guide groove 2.34 extends in the left and right direction, and the decorative panel 4 is provided with a second guide part 4.2 embedded in the second guide groove 2.34.

[0041] Through the above-mentioned guiding structure, each air guide plate 2 has good stability during relative movement, effectively preventing misalignment or jamming of the air guide plate 2 during left and right translation, and ensuring reliable operation of the air outlet device.

[0042] Please see Figure 8 As shown, the air guide hole 2.1 is a strip-shaped hole extending vertically; the narrow spacing of the strip-shaped holes in the left-right direction forms a nozzle structure, which improves the jetting effect of the airflow. Multiple air guide holes 2.1 are arranged on the air guide plate 2 along the left and right directions.

[0043] The above structural design is advantageous for manufacturing and facilitates airflow output and adjustment of the left and right air outlet angles.

[0044] The air guide plate 2 arches forward in the middle of the strip hole, making the strip hole have an arc-shaped forward protrusion structure.

[0045] The above improvements can expand the airflow output range in the vertical direction for a better user experience.

[0046] Please see Figure 3 As shown, a rotatable damper 5 is also provided in the air outlet channel 1.1 at the rear end of the guide vane 6. The opening of the air outlet channel 1.1 can be adjusted by the relative rotation of the damper 5 to control the air volume and thus meet more usage types.

[0047] 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.
