Description

Technical Field

[0001] This invention relates to the field of automotive parts, and more particularly to an automotive air vent structure and dashboard. Background Technology

[0002] The air vents in automobiles are located on the main and secondary dashboards. As crucial functional components in the interior, they are essential for passengers to perceive the direction of airflow adjustment. Their design affects the overall harmony of the interior, and with numerous internal parts, the manufacturing quality impacts the tactile experience for passengers. Currently, manual air vents typically feature straight-lined upper blades, resulting in a monotonous appearance. When space is limited for upper blade movement, the issue is often addressed by reducing the number of blades. However, manual air vents require adjustment knobs on the upper blades. If the number of upper blades is even, the knob placement can create visual asymmetry, giving the impression of an unrefined design. Alternatively, the dummy blade features can be integrated into the vent trim, making the surface treatment of the dummy blades indistinguishable from the trim's, leading to issues such as excessively wide electroplating and painting areas, further contributing to a less refined visual experience. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the purpose of this invention is to provide an automotive air vent structure and dashboard. Through the design of the upper blade structure and the separate design of the dummy blades, the vent's styling coordination can be improved.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0005] In a first aspect, embodiments of the present invention provide an automotive air vent structure, including an upper blade assembly, a dummy blade, and an air vent knob, wherein the dummy blade is detachably installed on the downward side of the upper blade assembly Z.

[0006] The upper blade assembly includes an even number of upper blades, and the air vent knob is installed on the middle blade among the upper blades and dummy blades; the upper blade includes a straight segment of a set length, and the two ends of the straight segment are connected to the arc segment as a whole, and the arc segment is adapted to the shape of the air vent trim.

[0007] As a further implementation, the adjustment stroke of the air vent knob on one side along the Y direction is less than the adjustment stroke on the other side.

[0008] As a further implementation, when the air outlet toggle is in its extreme states on both sides, the distance between the upper blade and the air outlet toggle is less than a set value.

[0009] As a further implementation, the set value ensures that there is no interference between the upper blades and the torsional motion of the air vent.

[0010] As a further implementation, the upper blade is connected to the upper blade support via a blade shaft, and the dummy blade is connected to the upper blade support via a limiting shaft.

[0011] As a further implementation, the upper blade support is provided with a shaft hole that mates with the blade shaft, and also with a square hole that mates with the limiting shaft.

[0012] As a further implementation, the diameter of the shaft hole is larger than the diameter of the blade shaft, and the cross-sectional dimensions of the limiting shaft are adapted to the square hole.

[0013] As a further implementation, the length of the straight line segment is greater than the length of the arc segment.

[0014] As a further implementation, the air outlet toggle includes a toggle body, a toggle base, and a toggle fork. The toggle body is installed on one side of the toggle base, and the toggle fork is installed on the other side. The toggle fork is used to drive the movement of the lower blades.

[0015] Secondly, embodiments of the present invention also provide an automotive dashboard in which the aforementioned air vent structure is installed.

[0016] The beneficial effects of this invention are as follows:

[0017] The upper blade of this invention includes a straight segment of a set length, with both ends of the straight segment connected to an arc segment to form an integral whole. The arc segment is adapted to the shape of the air vent trim, so that the appearance of the upper blade of the air vent tends to the shape curve, improving the visual coordination of the structure. Under the premise of shape locking, if there is insufficient space for the upper blade to move, a separate dummy blade of the air vent is added to distinguish the blade surface process from the trim, while satisfying the visual symmetrical arrangement of the toggle position, further improving the shape coordination of the air vent.

[0040] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. In the description of this invention, terms such as "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0041] For ease of description, the words "up," "down," "left," and "right" appearing in this invention only indicate that they are consistent with the up, down, left, and right directions of the accompanying drawings themselves, and do not limit the structure. They are merely for the purpose of facilitating the description of this invention and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0042] Example 1:

[0043] In existing technology, the upper blades of manually operated air vents are straight-line shaped, such as... Figure 16 and Figure 17 The traditional upper blade 21 shown has a rigid appearance that does not match the curved shape of the traditional air vent trim 22. Given that the air vent design cannot be changed, if there is insufficient space for the upper blades to move, the traditional solution has two approaches: one is to reduce the number of blades. Since manual air vents require adjustment knobs on the upper blades, when the number of upper blades is even, such as… Figure 19 As shown, there are four traditional upper blades 21, and the adjustment knob is located on the third traditional upper blade 21, creating visual asymmetry; secondly, the fake blades are placed on the traditional air vent trim 22, such as... Figure 18 As shown, the surface treatment process of the fake blades in this structural form is indistinguishable from that of the trim strip process, which will result in problems such as a large width of electroplating and painting, and an unrefined visual perception.

[0044] Based on this, this embodiment provides a car air vent structure, such as... Figure 2As shown, the automotive air vent structure mainly includes air vent sealing cotton 1, air vent housing 2, metal clip 3, lower blade support 4, lower blade assembly 5, upper blade support 20, upper blade assembly, upper blade damping 12, dummy blade 11, air vent knob, air vent painted trim 18, and air vent electroplated trim 19. In this embodiment, the up and down directions are X-direction, the left and right directions are Y-direction, and the height direction is Z-direction.

[0045] The upper blade assembly is mounted on the upper blade support 20. The upper blade assembly includes multiple upper blades evenly arranged along the Z-direction, and the upper blades are connected by upper blade connecting rods 7. In this embodiment, the upper blade assembly includes four upper blades, arranged according to... Figure 3 In the direction shown, from top to bottom, there are the first upper blade 6, the second upper blade 8, the third upper blade 9, and the fourth upper blade 10. The dummy blade 11 is located on the lower side (Z direction) of the fourth upper blade 10. The dummy blade 11 is also connected to the upper blade support 20.

[0046] In this embodiment, as Figure 3 As shown, the air vent knob is installed on the third upper blade 9. For all blades installed on the upper blade support 20, the air vent knob is located in the middle of all blades to ensure visual harmony. It can be understood that in other embodiments, such as when there are six upper blades, the air vent knob is installed on the fourth blade in the Z-direction from top to bottom.

[0047] like Figure 2 As shown, the air vent toggle includes a toggle base 14, a toggle body 16, a toggle damper 15, a toggle fork 13, and a toggle trim 17. The toggle body 16 is installed on one side of the toggle base 14, the toggle fork 13 is installed on the other side of the toggle base 14, the toggle damper 15 is installed between the toggle body 16 and the toggle base 14, and the toggle trim 17 is installed on the outside of the toggle body 16.

[0048] This embodiment uses the left-side air vent on the dashboard as an example. The adjustment range of the right side of the air vent knob is less than that of the left side. The specific adjustment range is related to the size of the air vent knob, air vent trim, etc. In this embodiment, such as... Figure 4 As shown, the width of the air vent knob is 39.1 mm, the adjustment stroke on the right side is 5.5 mm, and the adjustment stroke on the left side is 12.8 mm. These adjustment strokes ensure that the blades self-close when the air vent knob is moved to its limit position. The distance between the air vent knob and the tip of the upper blade is 0.5 mm. This value can be adaptively adjusted according to different process control capabilities, ensuring that there is no interference between the upper blade and the movement of the air vent knob.

[0049] In this embodiment, the shape of the upper blades conforms to the shape of the air vent housing 2, such as... Figure 5As shown, the upper blade includes a straight segment 25 in the middle and curved segments 26 on both sides, and the curved segments 26 and the straight segment 25 are integrally formed. The straight segment 25 is located in the middle and its length is greater than that of the curved segment 26, which can ensure the stability of the air vent's toggle movement. The curved segments 26 are set according to the shape of the air vent trim (including the air vent painted trim 18 and the air vent electroplated trim 19) and match the shape. The specific lengths of the straight segment 25 and the curved segments 26 are adapted to the actual air vent size. In this embodiment, the length of the straight segment 25 is 51mm, the arc of the right curved segment 26 is 20.29, and the arc of the left curved segment 26 is 25.83.

[0050] like Figure 6 and Figure 7 As shown, the air vent knob is in its rightmost extreme position, and the distance between the upper blade and the air vent knob is 0.3mm; Figure 8 and Figure 9 As shown, the air vent knob is in its left extreme position, and the distance between the upper blade and the air vent knob is 0.3mm; compared to Figure 4 In this state, the distance between the upper blades and the air outlet knob is reduced. The 0.3mm spacing is set to minimize the distance of the straight section of the blades. It should be noted that the value of 0.3mm can be adjusted according to different control requirements, as long as the movement of the upper blades and the air outlet knob is not interfered with.

[0051] In this embodiment, the total stroke of the air outlet toggle is 57.4 mm. The problem that the length of the straight section 25 of the upper blade (51 mm) is less than the total stroke of the toggle is absorbed by utilizing the distance between the upper blade and the air outlet toggle.

[0052] To address the issue of an unrefined visual appearance caused by the fake blades 11 being mounted on the vent trim, the fake blades 11 in this embodiment are designed as separate components. This allows for differentiation between the surface finish of the fake blades 11 and the vent trim, while also fulfilling the symmetrical arrangement requirement of the vent levers.

[0053] like Figures 10-15 As shown, the first upper blade 6, the second upper blade 8, the third upper blade 9 and the fourth upper blade 10 are installed sequentially from top to bottom along the Z direction of the upper blade support 20. Each upper blade is installed on the corresponding blade shaft 23. The upper blade support 20 has a shaft hole that matches the blade shaft 23. The diameter of the shaft hole is slightly larger than that of the blade shaft 23 to facilitate the movement of the upper blade.

[0054] The dummy blade 11 is mounted on the limiting shaft 24, which has a square cross-section. The upper blade support 20 has a square hole corresponding to the limiting shaft 24, and the size of the square hole is the same as that of the limiting shaft 24, so as to restrict the movement of the dummy blade 11 and facilitate the disassembly of the dummy blade 11. Through the structure of the dummy blade 11 which can be disassembled separately, the surface process of the dummy blade 11 can be distinguished from the trim.

[0055] In this embodiment, the blade shaft 23 has a diameter of 3 mm, the shaft hole diameter is 3.05 mm, and the limiting shaft 24 and the square hole have a size of 2 mm. 2mm. Of course, in other embodiments, the above dimensions can be adjusted according to actual requirements.

[0056] Compared to traditional air vent structures, this embodiment achieves a more curved appearance for the upper blades of the air vent while still allowing for manual adjustment, thus creating visual harmony. Furthermore, if insufficient space for movement of the upper blades occurs while maintaining the vent's shape, a separate dummy blade 11 is added to differentiate the blade's surface finish from the decorative strips. This also ensures visual symmetry in the toggle positions, further enhancing the overall harmony of the air vent's design.

[0057] Example 2:

[0058] This embodiment provides a car dashboard, such as Figure 1 As shown, the left air vent assembly A, right air vent assembly B, and middle air vent assembly C on the dashboard can adopt the air vent structure described in Embodiment 1. Depending on the vehicle model, some models may also have a rear air vent assembly D, which can also adopt the air vent structure described in Embodiment 1.

[0059] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
