Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, and more specifically to an automotive air outlet device based on a multi-layer air guide plate. 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.

[0004] 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.

[0005] 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. Summary of the Invention

[0006] To address the shortcomings and defects of existing technologies, a compact and low-cost automotive air outlet device based on a multi-layer air guide plate is provided.

[0007] A car air vent device based on a multi-layer air guide plate includes:

[0008] An air outlet housing, the interior of which defines an air outlet channel extending along a first direction E;

[0009] Multiple air guide vanes are arranged in a front-to-back configuration along the first direction E in the air outlet channel, and can be moved left and right perpendicular to the first direction E.

[0010] Each air guide plate has an air guide hole at a corresponding position, and the air guide holes at corresponding positions are connected in sequence to form a flow channel that can be bent left and right. The flow channel is connected to the air outlet channel.

[0011] A rotating disk is rotatable about an axis F, and the rotating disk is provided with a plurality of transmission pins spaced apart along its radial direction G;

[0012] Each air guide plate is provided with a drive groove that forms a transmission engagement with a unique corresponding drive pin. When the rotating disk rotates, the drive pins at different radial positions generate different tangential displacements, thereby driving each air guide plate to generate different left and right translations, causing relative offset between the air guide holes of adjacent air guide plates, and thus continuously changing the air outlet angle of the air guide channel.

[0013] With the above structure, the automotive air outlet device based on a multi-layer air guide plate of the present invention has the following advantages compared with the prior art:

[0014] Taking an arrangement where the rotation radius of the drive pins gradually decreases from front to back as an example: The drive pin with the larger rotation radius has a larger tangential displacement, resulting in a larger displacement of the guide vane.

[0015] A transmission pin with a small radius of rotation has a small tangential displacement, resulting in a small displacement of the air guide plate.

[0016] In the manner described above, the rotating disk drives the air guide plate to move left and right through the cooperation structure of the transmission pin and the drive groove. Each air guide plate can produce different left and right translation amounts, so that the air guide holes of adjacent air guide plates are offset relative to each other, thereby continuously changing the air outlet angle of the guide channel. When the airflow passes through the guide channel, it is guided and output according to the direction after the angle change.

[0017] Compared with the air guide components of existing air outlet devices, the air outlet channel of this application does not require multiple sets of linked air guide blades to be arranged, and the air outlet angle can still be adjusted.

[0018] The air guide plate is thinner than the air guide blade in the front-to-back direction, and the front-to-back depth of the air outlet channel is shallow enough to meet the installation requirements. The entire air outlet device is more compact and suitable for use in cars with limited space.

[0019] In addition, the air guide plate does not require a linkage structure to achieve linkage, which effectively reduces costs.

[0020] As an improvement of the present invention, the rotating disk is disposed behind the air guide plate.

[0021] The axis F of the rotating disk, the vertical center line of the air guide plate, and the mating center line of the transmission pin and the drive groove are all located in the same plane.

[0022] As an improvement of the present invention, the number of rotating disks is two, the two rotating disks are arranged coaxially at intervals, and they are kept rotating synchronously by a linkage.

[0023] The air guide plate is provided with a drive groove that independently cooperates with the transmission pins on the two rotating disks. The rotating disks drive the air guide plate to move left and right through the cooperation structure of the two sets of transmission pins and the drive grooves.

[0024] As an improvement of the present invention, each air guide plate has a rearwardly extending connecting portion at both the upper and lower ends, and the driving groove is disposed on the connecting portion.

[0025] As an improvement of the present invention, the corresponding relationship between the drive grooves and transmission pins of adjacent air guide plates in the front-rear direction is as follows: the drive groove on the front air guide plate is engaged with the transmission pin with small tangential displacement.

[0026] The drive groove on the rear air guide plate is engaged with the transmission pin with large tangential displacement.

[0027] As an improvement of the present invention, the air guide hole is a strip-shaped hole extending vertically.

[0028] As an improvement of the present invention, the air guide plate arches forward in the middle of the strip hole, so that the strip hole has an arc-shaped forward protrusion structure.

[0029] As an improvement of the present invention, the air outlet housing is provided with a decorative panel, and an assembly space is formed between the decorative panel and the air outlet housing.

[0030] The air guide plate is placed in the assembly space and is limited by the assembly space to move left and right.

[0031] As an improvement of the present invention, each air guide plate has an extension portion extending vertically at its upper or lower end, adjacent extension portions are stacked in front and behind, and a sliding block and a sliding groove structure that fits into each other are provided between the front and rear end faces. When adjacent air guide plates move left and right, they are guided by the cooperation structure of the sliding block and the sliding groove.

[0032] The extension at the rear position is provided with a first guide portion, and the air outlet housing is provided with a first guide groove extending in the left and right direction, and the first guide portion is embedded in the first guide groove;

[0033] The front extension is provided with a second guide groove extending in the left-right direction, and the decorative panel is provided with a second guide portion embedded in the second guide groove. Attached Figure Description

[0046] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0047] Please see Figure 1-5 , Figure 7 , Figure 11 As shown,

[0048] A car air vent device based on a multi-layer air guide plate includes:

[0049] An air outlet housing 1, the interior of which defines an air outlet channel 1.1 extending along a first direction E;

[0050] Multiple air guide vanes 2 are arranged in a front-to-back configuration along the first direction E in the air outlet duct 1.1, and can be moved left and right perpendicular to the first direction E.

[0051] Each air guide plate 2 has an air guide hole 2.1 at a corresponding position, and the air guide holes 2.1 at corresponding positions are connected in sequence to form a flow channel that can be bent left and right. The flow channel is connected to the air outlet channel 1.1.

[0052] The rotary disk 3 can rotate left and right around the axis F perpendicular to the first direction E under the drive of the actuator 7. The rotary disk 3 is provided with a plurality of transmission pins 3.1 distributed at intervals along its radial direction G.

[0053] Each air guide plate 2 is provided with a drive groove 2.21 that forms a transmission engagement with a unique corresponding drive pin 3.1.

[0054] Among them, the transmission pin 3.1 extends along a direction parallel to the axis F, the drive groove 2.21 extends back and forth, and the distance between the left and right sides of the drive groove 2.21 is slightly larger than the diameter of the transmission pin 3.1, so that it can contact the transmission pin 3.1.

[0055] When the rotating disk 3 rotates, the transmission pins 3.1 at different radial positions produce different tangential displacements.

[0056] Taking the arrangement of the transmission pins 3.1 with gradually decreasing rotation radius from front to back as an example: among them, the transmission pins 3.1 with larger rotation radius have larger tangential displacement, and thus drive the air guide plate 2 to a larger displacement.

[0057] The transmission pin 3.1 with a small rotation radius has a small tangential displacement, and the displacement of the guide plate 2 it drives is small;

[0058] In the manner described above, the rotating disk 3 drives the air guide plate 2 to move left and right through the cooperation structure of the transmission pin 3.1 and the drive groove 2.21. Each air guide plate 2 produces a different left and right translation amount, so that the air guide holes 2.1 of adjacent air guide plates 2 are relatively offset, thereby continuously changing the left and right air outlet angle of the guide channel. When the airflow passes through the guide channel, it is guided and output according to the direction after the angle change.

[0059] Compared with the air guide components of existing air outlet devices, the air outlet channel 1.1 of this application does not require multiple sets of linked air guide blades 6 to be arranged, and the air outlet angle can still be adjusted.

[0060] The air guide plate 2 is thinner than the air guide blade 6 in the front-to-back direction, and the front-to-back depth of the air outlet channel 1.1 is shallow enough to meet the installation requirements. The entire air outlet device is relatively compact and suitable for use in cars with limited space.

[0061] In addition, the air guide plate 2 does not require linkage structure to achieve linkage, which effectively reduces costs.

[0062] Please see Figure 3 , Figure 4 , Figure 7 As shown, the rotating disk 3 is located behind the air guide plate 2, which makes the structural layout reasonable and the space utilization rate higher.

[0063] 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. After the above improvement, 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, which enables the air guide plate 2 to move more stably from left to right, thereby enabling the air guide channel to form a bending effect effectively and reliably to guide the airflow.

[0064] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, there are two rotating disks 3, which are arranged coaxially at intervals and are kept in synchronous rotation by a linkage 3.2.

[0065] The air guide plate 2 is provided with a drive groove 2.21 that independently cooperates with the transmission pins 3.1 on the two rotating disks 3. The rotating disks 3 are driven by the cooperation structure of the two sets of transmission pins 3.1 and the drive grooves 2.21 to move the air guide plate 2 left and right.

[0066] 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.

[0067] In some embodiments, the rotating disk 3 is positioned at the upper and lower ends corresponding to the air guide plate 2, and the drive pins 3.1 of both are arranged inwards.

[0068] Furthermore, the two drive slots 2.21 on the air guide plate 2 are also arranged at the upper and lower ends of the air guide plate 2.

[0069] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, each air guide plate 2 has a rearwardly extending connecting part 2.2 at both the upper and lower ends. The drive groove 2.21 is set on the connecting part 2.2, so that the connection position of it and the transmission pin 3.1 is arranged on the connecting part 2.2 behind the air guide plate 2, without occupying the area of ​​the air guide plate 2, and the air guide plate 2 can be made thinner overall.

[0070] 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.

[0071] The correspondence between the drive groove 2.21 and the transmission pin 3.1 of adjacent air guide plates 2 in the front-rear direction is as follows: the drive groove 2.21 on the front air guide plate 2 is engaged with the transmission pin 3.1 with small tangential displacement.

[0072] The drive groove 2.21 on the rear air guide plate 2 is engaged with the transmission pin 3.1 with large tangential displacement.

[0073] In some embodiments, the front air deflector 2 is exposed to the occupants' field of vision; if it shifts significantly, it may affect the visual effect.

[0074] After the above improvements, the rear air deflector 2 has a larger displacement and the front air deflector 2 has a smaller displacement, which can present a better visual effect within the user's field of vision and improve the user experience.

[0075] Please see Figure 8 As shown, the air guide hole 2.1 is a vertically extending strip-shaped hole. The narrow spacing of the strip-shaped holes in the left-right direction forms a nozzle structure, which improves the airflow projection effect.

[0076] Multiple air guide holes 2.1 are arranged on the air guide plate 2 along the left and right directions.

[0077] The above structural design is advantageous for manufacturing and facilitates airflow output and adjustment of the left and right air outlet angles.

[0078] Please see Figure 8 As shown, the air guide plate 2 arches forward in the middle of the strip hole, making the strip hole have an arc-shaped protruding structure.

[0079] The above improvements can expand the airflow output range in the vertical direction for a better user experience.

[0080] Please see Figure 9 , Figure 10 As shown, the air outlet housing 1 is provided with a decorative panel 4, and an assembly space 4.1 is formed between the decorative panel 4 and the air outlet housing 1;

[0081] The air guide plate 2 is placed in the assembly space 4.1 and is limited by the assembly space 4.1 to move left and right. The air guide plate 2 can be covered by the decorative plate 4 to obtain a better visual effect.

[0082] In some embodiments, each air guide plate 2 has an extension portion 2.3 extending vertically at its upper or lower end, adjacent extension portions 2.3 are stacked one after the other, and a sliding block 2.31 and a sliding groove 2.32 structure that fits into each other are provided between the front and rear end faces. When adjacent air guide plates 2 move left and right, they are guided by the cooperation structure of the sliding block 2.31 and the sliding groove 2.32.

[0083] The extension 2.3 at the rear position is provided with a first guide 2.33, 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 2.33 is embedded in the first guide groove 1.2;

[0084] The front extension 2.3 is provided with a second guide groove 2.34 extending 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.

[0085] 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.

[0086] Please see Figure 3 As shown, in some embodiments, multiple interconnected air guide blades 6 are provided in the air outlet channel 1.1 at the rear end of the air guide plate 2. The air guide blades 6 are configured to swing up and down to change the up and down air outlet angle of the airflow.

[0087] In some embodiments, a rotatable damper 5 is also provided in the air outlet channel 1.1 at the rear end of the guide vane 6, and the opening of the air outlet channel 1.1 is adjusted by the relative rotation of the damper 5.

[0088] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
