Description

Technical Field

[0001] This invention relates to an air outlet device for vehicles, particularly for road vehicles (such as cars, trucks, or buses). Background Technology

[0002] Various forms of air outlet devices, or in other words, vents, are known. These air outlet devices or vents are used to set and change the direction of airflow into the vehicle interior. A typical task of an air outlet device is to provide the possibility of guiding airflow from the user's perspective in the left-right direction and / or up-down direction. In addition, it is generally desirable for air outlet devices to have a shut-off function, by means of which the airflow toward the user can be significantly reduced and preferably completely shut off.

[0003] DE 10 2017 004 928 A1 discloses ventilation holes with corresponding closing functions, provided by a relatively spacious rudder. Utility Model Content

[0004] One object of this invention is to provide a compact air outlet device by which the direction of airflow can be reliably set, and by which the intensity of airflow can be significantly reduced and preferably completely shut off.

[0005] This objective is achieved by means of the subject matter of the independent claims. Preferred embodiments are set forth in the dependent claims and in this specification.

[0006] Therefore, an air outlet device for a vehicle is disclosed, the air outlet device comprising:

[0007] - A housing having an air passage for guiding airflow along an airflow axis that extends from an air inlet to an air outlet.

[0008] - An air guiding element that divides an air channel into a first channel segment and a second channel segment, the air guiding element having a first air guiding surface that partially defines (or in other words limits) the first channel segment and a second air guiding surface that partially defines the second channel segment, wherein at least one of the first air guiding surface and the second air guiding surface includes a step.

[0009] - At least one airflow regulator, the at least one airflow regulator being pivotable about a pivot axis extending at an angle relative to the airflow axis, wherein the airflow regulator has a first blade arranged in a first channel section and a second blade arranged in a second channel section.

[0010] -The airflow regulator is pivotable such that one of the first blade and the second blade (e.g., the corresponding one in the same first channel section or second channel section as at least one step) contacts the step.

[0011] By providing a step, near-complete or even complete closure of the airflow through one of the first and second blades can be achieved. In other words, one of the first and second blades, along with at least one step, can cooperate to significantly reduce, and in particular, completely block, the airflow. This limits the need for other closing mechanisms. Additionally or alternatively, the step can act as a stop for limiting the pivoting movement of the airflow regulator. Once stopped, a fluid seal can be achieved through the adjacent blades of the multiple airflow regulators that overlap and / or contact each other.

[0012] In a manner generally known, an airflow regulator can provide an air-guiding effect about a pivot axis. For example, when installed in a vehicle, the pivot axis can be substantially vertical, allowing the airflow regulator to be configured to guide airflow to the left or right from the perspective of vehicle passengers. The functionality of the airflow regulator is extended by currently proposed cooperation with a step to provide a (at least partially and preferably completely) shut-off effect regarding airflow. In other words, by configuring an airflow regulator and a step as disclosed herein, the functions of airflow guidance and airflow shut-off can be integrated.

[0013] Furthermore, compactness can be achieved because the additional components that have been necessary to achieve the corresponding closing effect can be reduced or even completely omitted. This also allows for a corresponding reduction in the housing size that must accommodate these additional components in existing solutions.

[0014] The airflow may flow at least partially parallel to and / or at an angle to the airflow axis. The angle may optionally be less than 90°, and more preferably less than 60°. Generally, in the context of this disclosure, extension along an axis or direction may involve an orientation of less than 90° or less than 60° relative to said axis or direction. For example, the airflow axis may be straight, but the actual airflow may have a curved or angled path, for example, passing through an air guide element while still extending along the airflow axis.

[0015] The air inlet may face the vehicle's interior air duct, which is fluidly connected to an airflow generator, such as a fan. The air outlet may face the interior of the vehicle or generally face the space into which the airflow will be directed.

[0016] The air passage may be enclosed by the housing, for example, separated from air inlets and air outlets. The air passage may include or define a hollow space within the housing. The air passage may accommodate structures, such as guiding elements, any airflow regulators discussed herein, or at least a portion of any moving mechanism for these components.

[0017] Air guiding elements (e.g., surfaces facing the air inlet) may extend at an angle, particularly perpendicular, to the airflow axis. Air guiding elements may extend between and / or connect to the opposing sidewalls of the air passage. Airflow may pass through and / or along the air guiding elements (particularly only) through the first and second passage sections, but not, for example, through the interior of the air guiding elements.

[0018] The first and second channel sections may extend at an angle, particularly perpendicular, to the airflow axis. Additionally or alternatively, the first and second channel sections may extend between and / or connect to the opposing sidewalls of the air passage. The first and second channel sections may be defined by the inner surface or inner wall of the housing facing one of the first and second air guiding surfaces. The first channel section may define or be included in the gap between the first air guiding surface and the opposing inner surface of the housing (particularly along the pivot axis), while the second channel section may define or be included in the gap between the second air guiding surface and the opposing inner surface of the housing (particularly along the pivot axis). Therefore, the first and second air guiding surfaces can generally be considered to define only partially the first and second air passage sections, respectively, because the first and second air passage sections cooperate with other sections (e.g., housing sidewalls) to effectively and completely define the air passage sections.

[0019] By utilizing air guiding elements and their air guiding surfaces to distribute airflow, the direction of airflow can be adjusted, especially along the vertical up-down direction. As described in detail below, this can be achieved in conjunction with another air guiding element (e.g., a baffle).

[0020] Typically, the air guiding element can be hollow. The first and second surfaces can form a shell or wall, for example, surrounding the hollow internal space of the air guiding element.

[0021] The air guiding element can be a single-piece component or a multi-piece component. In the latter case, a component may include a step. Optionally, the step may be adjacent to at least one other component forming the air guiding element. For example, the step may be adjacent to and / or include a connecting portion or interface for connection to a corresponding other component. In one example, the air guiding element includes two components, for example, each component including at least a portion of a first air guiding surface and / or at least a portion of a second air guiding surface. Additionally or alternatively, the two components may be connected to each other along a plane including a pivot axis or in a plane extending parallel to a plane including a pivot axis (and for example parallel to the longitudinal axis of the air guiding element discussed below). Additionally or alternatively, one component may face the air inlet, and one component may face the air outlet.

[0022] Each component of the assembly, also referred to as an air guiding element, may include a portion of a bearing surface for pivotally supporting the airflow regulator. For example, the airflow regulator, particularly its connecting portion or pivot shaft, may be accommodated between the components. Each component may, for example, include a semi-circular or tubular bearing portion against which the connecting portion and / or pivot shaft may abut. Accommodating the airflow regulator between the components of the air guiding element simplifies assembly. For example, the airflow regulator can be easily inserted between the components before they are connected (e.g., by forming a snap-fit ​​connection) and can then be securely held between the components.

[0023] When the air outlet device is installed in a vehicle, the pivot axis can extend vertically or at an angle of less than 20° relative to the vertical axis of space. The vertical direction can correspond to the direction of gravity. Therefore, the first blade and the second blade can form a vertical blade. The first blade and the second blade can be considered as a blade interrupted by an airflow guiding element and / or as a blade arrangement that accommodates the airflow guiding element between the first blade and the second blade (e.g., when viewed along the pivot axis).

[0024] The first and second blades can pivot together about a pivot axis. The airflow regulator can be a single-piece or multi-piece component, wherein, for example, the first and second blades are connected so as to pivot together about a pivot axis. Both the first and second blades can be plate-shaped or flat components. The first and second blades can extend along the pivot axis. The first and second blades can extend substantially perpendicularly and / or uprightly relative to the corresponding one of the first and second air guiding surfaces. In one example, the first and second blades can both extend at an angle (e.g., an angle greater than 60°) and particularly perpendicularly to a plane defined by the airflow axis and the longitudinal axis of the air guiding element discussed below. The first and second blades can have similar dimensions and / or similar orientations.

[0025] Each blade can be pivotable, such that its side edges face the air inlet and / or air outlet. In this orientation, the blade may not redirect the airflow from the air inlet to the air outlet, or may redirect it only to a very small extent. When the blade is pivoted, the blade surface (e.g., the plate-like portion) can be oriented towards the air inlet and outlet. For example, the angle between the airflow axis and the blade (especially the blade surface or plate-like portion) can be increased, causing the airflow to be redirected by the blade.

[0026] The first and second blades can be connected via at least one connecting portion of the airflow regulator. The connecting portion can be at least partially housed within the air guiding element, for example, within the hollow space described above. The connecting portion may include a connecting part for coupling to a moving mechanism. The moving mechanism can apply pivoting forces to the airflow regulator. The connecting portion and / or the moving mechanism can be at least partially housed within the guiding element, for example, within the hollow space discussed above. This prevents airflow deformation caused by the moving mechanism.

[0027] According to embodiments of this disclosure, the step can be used as a stop element for the pivotal movement of the airflow regulator. The step can also serve as a sealing surface that, when contacted by a corresponding one of the first and second blades, provides a largely or substantially completely airtight seal.

[0028] According to one aspect, the step defines a height difference along the pivot axis in one of the first and second air guiding surfaces. In particular, when viewed from the air inlet to the air outlet, the step may define a greater height along the pivot axis in one of the first and second air guiding surfaces. The definition of the corresponding difference may apply only to sections of the step (e.g., sections along the longitudinal axis of the air guiding element discussed below), such sections extending, for example, along the recesses discussed below.

[0029] In one example, the step forms an angle of at least 20° or preferably at least 60° with the airflow axis. This angle can be, for example, up to and including 90°, or up to and including 120°, or up to and including 160°. The step can have a front, particularly a flat front. This front can extend along the longitudinal axis of the air guide element discussed below and / or along the pivot axis. The angle between the step and the airflow axis can be defined between the front and the airflow axis. In one example, the step and / or its front extends parallel to or includes the pivot axis (or a plane defined by the longitudinal axis of the guide element and the pivot axis).

[0030] Additional or alternative land, the staircase, especially its optional front, can face the air inlet.

[0031] According to another embodiment, the air guiding element has a longitudinal axis extending perpendicular to the airflow axis, and a pivot axis extending perpendicular to said longitudinal axis. Additionally or alternatively, the longitudinal axis may extend along the maximum dimension of the air guiding element and / or between opposite sidewalls of the housing. The steps (especially their optional front) may form an angle of less than 20° with the longitudinal axis.

[0032] Any of the above-described exemplary designs and extensions of the ladder contribute to improving the reliability of its optionally intended stopping and / or sealing functions.

[0033] In another example, the first and second blades, pivotable to contact a respective step (e.g., located in the same first or second channel segment as at least one step), include a first protrusion extending at an angle relative to the pivot axis. The first protrusion may also be referred to as a rib. The first protrusion may be a flat and / or plate-like member. The first protrusion may be curved. The first protrusion may extend substantially perpendicular to the remainder of the respective blade and / or the pivot axis. The first protrusion may extend along and / or substantially parallel to a respective one of the first and second air guiding surfaces (and / or the respective opposing inner surfaces of the housing) that includes the step. The main region, main surface, or main face of the first protrusion may extend at an angle to the pivot axis. For example, the protrusion may have a surface facing the air guiding element and a surface facing away from the air guiding element, these surfaces extending or defining, for example, the main (possibly curved) region of the first protrusion.

[0034] The first protrusion can provide an air guiding effect. For example, the first protrusion can help limit or avoid turbulence that might otherwise occur when airflow passes over a step. Conversely, even at or after a step, the first protrusion can guide the airflow to continue along the air guiding element.

[0035] The first protrusion may be arranged (e.g., in the neutral position of the airflow regulator) or can be arranged (e.g., by pivoting accordingly) opposite the step. For example, when viewed along the pivot axis, the first protrusion may be arranged beside and / or above or below the step. In one example, at any pivot position of the airflow regulator, the first protrusion (at least a portion of it) is arranged opposite the step.

[0036] Additionally or alternatively, the first protrusion may extend between the respective opposing inner surfaces of the step and the housing. When viewed along the airflow axis, the first protrusion may overlap the step. In the context of this disclosure, the overlapping arrangement may include overlapping elements extending along the same portion of a common reference axis. In other words, the first protrusion may cover the step or may obscure the step.

[0037] In one aspect, a portion of the airflow can be guided through the gap between the first protrusion and the step. The first protrusion can guide and / or direct the airflow through the step, particularly along a path similar to the curvature of the corresponding one of the first and second air guiding surfaces (e.g., the curvature before or after the step when viewed along the airflow axis).

[0038] The surface of the first protrusion facing the step (and / or the surface facing away from the step) can be concave or may have another curvature. In one example, the surface facing the step is concave, while the surface facing away from the step is convex. Additionally or alternatively, at least the surface facing the step (and optionally the surface facing away from the step) may have a Coanda shape and / or a Coanda-like surface. Configuring the first protrusion to have curvature according to any of the examples disclosed herein provides a particularly reliable air guiding effect to eliminate turbulence that might otherwise occur at the step.

[0039] Further developments indicate that, when viewed along the airflow axis and in the direction from the air inlet to the air outlet, the first protrusion extends opposite the area of ​​the air guiding element located in front of the step and opposite the area located behind the step. In other words, the first protrusion can overlap with the step and the adjacent area in both directions along the airflow axis. The length of the first protrusion along the airflow axis can typically reach several centimeters, for example, between 1 cm and 10 cm, or can be at least 2 cm or at least 4 cm. This ensures reliable air guiding while also achieving a compact overall air outlet device.

[0040] In one aspect, the air guiding element is rigidly, or in other words, immovably arranged in the air passage. For example, the air guiding element can be fixedly attached to the side wall of the air passage. This limits the complexity of the mechanism and improves the ease of use of the air outlet device.

[0041] The airflow guiding element (or at least its first and second air guiding surfaces) can be symmetrical, for example, with respect to a plane including the pivot axis and the airflow axis. Typically, the airflow guiding element can have a circular, elliptical, or lens-shaped shape, especially the cross-section of the corresponding shape. The cross-sectional region can extend within or parallel to the plane including the pivot axis and the airflow axis. The dimension of the airflow guiding element along the airflow axis can be longer than the dimension of the airflow guiding element along the pivot axis. The longest dimension of the airflow guiding element can extend along the longitudinal axis.

[0042] In one embodiment, each of the first and second air guiding surfaces is convexly curved. Optionally, both the first and second air guiding surfaces define a Coanda surface. A Coanda surface can be a surface configured to generate an airflow exhibiting the Coanda effect (e.g., considering a minimum, maximum, or moderate airflow). The Coanda effect involves the tendency of fluid along a surface, for example, such that the flow path resembles the shape of the surface. Each of the first and second air guiding surfaces may define at least one Coanda surface adjacent to a step and / or adjacent to an optional recess (see below) for accommodating a portion of the blade. The surface of the first protrusion facing and / or away from the air guiding element may similarly define a Coanda surface.

[0043] In another embodiment, when viewed along the airflow axis and in the direction from air inlet to air outlet, the corresponding one of the first and second blades contacting the step (e.g., located in the same first or second channel segment as at least one step) includes a first segment that is pivotable along the area of ​​the air guide element located in front of the step. Additionally or alternatively, the first and second blades may include a second segment that is pivotable along the area of ​​the air guide element located behind the step (again, when viewed along the airflow axis and in the direction from air inlet to air outlet). Thus, the blades can, for example, cover, shield, or overlap the step in both directions along the airflow axis. In particular, the edge of the blade facing the airflow guide element can overlap the step. The edge can typically have a shape similar to the shape of the step (and / or the height profile along the pivot axis) of the air guide surface facing the edge. In other words, the blade can span or extend across the step (e.g., when viewed along the airflow axis).

[0044] In this configuration, the first segment can extend further along the pivot axis than the second segment, particularly in the direction toward the corresponding other of the first and second blades (and / or toward the corresponding adjacent or opposing air guide surfaces). For example, the first segment can project further along the pivot axis than the second segment relative to the geometric center of the corresponding blade. This facilitates a stepped shape similar to the adjacent air guide surfaces, allowing the blades to be closely aligned with said air guide surfaces. This helps prevent airflow from flowing at least partially through the gap between the blades and the air guide surfaces without being guided by the blades in a defined manner.

[0045] Additionally or alternatively, the air guide element may include a recess for receiving a first segment of the blade in any pivoting position of the blade. In other words, the position and size of the recess can accommodate the first segment of the blade along the entire stroke of the blade when pivoting about a pivot axis. The recess may be flat and / or may have curvature that deviates from the curvature of the boundary portion of the corresponding air guide surface. The recess allows the first segment to be arranged close to the air guide element while at least the boundary portion of the corresponding air guide surface can retain its (e.g., Coanda) shape.

[0046] The blade may be specified to include a second protrusion. This second protrusion may be arranged, or can be arranged, opposite to the recess and / or a portion defining the recess of the air guide element. In other words, the second protrusion may cover, shield, or overlap the recess and / or a portion defining the recess. The second protrusion can generally be configured according to any example of the first protrusion (e.g., in terms of shape and size). However, the second protrusion may be arranged on a different side of the blade compared to the first protrusion. In other words, the first and second protrusions may be positioned on opposite sides of the blade, for example, where these sides face different sidewalls of the housing. Similar to the first protrusion, the second protrusion can help limit or avoid turbulence, for example, due to at least a partial deviation from the curvature of the corresponding air guide surface.

[0047] It can be specified that the portion defining the recess (in other words, the edge of the recess) extends further than the step along the pivot axis and toward the opposite surface of the housing. In other words, the portion defining the recess can protrude relative to the step, for example, toward the opposite surface of the housing. This can facilitate guiding airflow smoothly through the step and / or toward the second protrusion.

[0048] According to one example, the portion defining the recess has a curved surface. The edge of a corresponding one of the first and second blades is movable along said curved surface. When pivoting about a pivot axis, the curvature of said surface can approximate the path of movement of said edge. The curved surface can help limit the gap between said edge and the air guide element, thereby limiting the risk of airflow passing at least partially across the air guide element in a non-directional manner.

[0049] Any boundary portion of the recess (e.g., either of two boundary portions spaced apart from each other along the longitudinal axis) can be used as a stop member to restrict the pivoting movement of the airflow regulator. For example, a boundary portion can be used as a corresponding stop member to restrict pivoting movement in a first direction, while a step can be used as a stop member to restrict pivoting movement in a corresponding other direction.

[0050] According to another example, when viewed along the airflow axis, the pivot axis is positioned closer to the (e.g., geometric) center of the air guide element (especially its cross-section extending perpendicularly to the longitudinal axis) than to the axial end of the air guide element. The axial end may refer to an axial end along the airflow axis. By positioning the pivot axis accordingly, compactness can be increased due to the increased overlap between the airflow regulator and the air guide element along the airflow axis.

[0051] According to another aspect, a plurality of airflow regulators are provided. These airflow regulators are all pivotable to contact and / or overlap with at least one other airflow regulator. The airflow regulators can be configured according to any of the examples disclosed herein. The airflow regulators can be identical to each other. The airflow regulators can be arranged in series along the longitudinal axis of the air guiding element. The airflow regulators can pivot together and / or be oriented identically to each other relative to the pivot axis. In other words, the pivot angles of the airflow regulators can be identical and can be equally variable, for example, due to coupling to a common moving mechanism.

[0052] To make contact with each other, the airflow regulators can pivot to contact the step or present the minimum possible angle relative to the step. This step can typically extend along all the airflow regulators. In this position, the angle between the airflow regulator blades and the airflow axis can be maximized. Each airflow regulator can contact at least one adjacent airflow regulator (e.g., adjacent along the longitudinal axis) and / or overlap with another airflow regulator along the longitudinal axis. An airflow regulator positioned between two airflow regulators along the longitudinal axis can contact and / or overlap with both of the other two airflow regulators.

[0053] Contact and / or overlap can occur along the sides of the blades. This prevents or significantly restricts airflow through the blades. Optionally, the upper or outer edge of a blade facing the opposite inner surface of the housing may contact the inner surface or may be spaced only slightly apart from it (e.g., less than 5 mm or less than 1 mm). Additionally or alternatively, the lower or inner edge of a blade facing the opposite inner surface of the housing may contact the inner surface or may be spaced only slightly apart from it (e.g., less than 5 mm or less than 1 mm). Thus, when the blades additionally contact the step or move close to the step and / or contact each other, airflow through the two air passage sections can be significantly reduced, especially when completely blocked.

[0054] The airflow regulator and / or air guiding element may be symmetrical with respect to a plane including the airflow axis and the longitudinal axis or a plane extending parallel to the plane including the airflow axis and the longitudinal axis.

[0055] In another example, both the first and second blades include a first protrusion, both the first and second air guide surfaces include a step, and each first protrusion is arranged or can be arranged opposite to the step of a corresponding one of the first and second air guide surfaces. This can provide the advantage of the step, for example, regarding increased closure capability in the two air passage sections.

[0056] The air outlet device may also include an airflow distributor configured to adjustably distribute airflow between a first channel section and a second channel section. This airflow distributor is pivotable about an axis extending at an angle, particularly perpendicular to, the pivot axis of the airflow regulator. The airflow distributor may have a plate-like shape. The airflow distributor may also be referred to as a baffle or rudder. The airflow distributor may be hinged to an air guiding element, particularly to its side facing the air inlet. The airflow distributor may be pivotable to contact the inner surfaces of the housing, particularly a pair of inner surfaces opposite each other when viewed along the pivot axis of the airflow regulator. When the respective inner surfaces are in contact, airflow entering one air channel section can be completely blocked. Attached Figure Description

[0066] Figure 1 This is a partial cross-sectional view of an air outlet device 10 according to an embodiment of the present invention. The air outlet device 10 is installed in a vehicle to provide airflow to the interior of the vehicle.

[0067] The air outlet device 10 includes a housing 12. The housing 12 surrounds an air passage 14 (i.e., an empty space that accommodates other components discussed below). The air passage 14 connects the air inlet 16 and the air outlet 18 of the air outlet device 10. Figure 1 The airflow axis A extending between air inlet 16 and air outlet 18 is shown.

[0068] Airflow is received from other vehicle components (not shown) via air inlet 16 and flows into the vehicle interior via air outlet 18. As described in detail below, air outlet device 10 is configured to regulate the direction and intensity of the airflow exiting air outlet 18.

[0069] Multiple components are arranged within the housing 12 and therefore within the air passage 14. These include immovable air guiding elements 20 and multiple pivotable airflow regulators 22. Additionally, an optional airflow distributor 24 is shown. Further components, not shown, may be provided, such as those included in the moving mechanism for moving the airflow regulators 22 and / or the airflow distributor 24.

[0070] Figure 1 The longitudinal axis L is also shown, along which the guide element 20 is positioned on the opposite sidewall 26 of the housing 12. Figure 1 Only one of them is visible in the diagram. Furthermore, a pivot axis P is shown for one airflow regulator 22 about which it can pivot. Other pivot axes P for the other airflow regulators 22 extend parallel to the depicted pivot axis. Additionally, a pivot axis D is shown about which the airflow distributor 24 pivots. Figure 1 The cross-sectional plane includes the depicted pivot axis P and airflow axis A, and extends perpendicular to the pivot axis D and longitudinal axis L.

[0071] Figure 1 The orientation of the air outlet device 10 when installed in a vehicle is shown. Thus, the pivot axis P extends vertically, while the other axes A, D, and L extend horizontally. References to directions such as upper and lower can refer to corresponding positions along the pivot axis P.

[0072] For reference Figure 2 To further explain, the air guiding element 20 defines two air passage segments 28, 30. Specifically, the air passage 14 is divided into said air passage segments 28, 30 when moving from the air inlet 16 to the air outlet 18. For this purpose, the air guiding element includes a first (in Figure 1 (Middle to upper part) Air guiding surface 32 and second (in Figure 2 (Lower middle section) Air guiding surface 34. These portions, together with the respective opposing inner surfaces 36 of the housing 12 (and together with the side wall portions 26 of the housing 12), define, or in other words demarcate, air passage sections 28, 30.

[0073] The air guiding element 20 has a circular and substantially oval or elliptical cross-section. An elliptical axis (particularly the main axis) of the cross-section coincides with or is alternatively parallel to the airflow axis A. In the example shown, the air guiding element 20 is a two-piece component comprising an assembly 38 facing the air outlet 18 and an assembly 40 facing the air inlet 16. Both assemblies 38 and 40 include portions of air guiding surfaces 32 and 34.

[0074] Both air guiding surfaces 32 and 34 are convexly curved. Each air guiding surface forms two halves of the cross-section of the air guiding element 20 (e.g., oval or elliptical). The air guiding surfaces define a Coanda surface such that airflow follows its shape, such as... Figure 2 The arrows in the figures indicate the flow path of the airflow through the airflow device 10. Typically, the flow path of the airflow through the airflow device 10 is shown by arrows in all the figures.

[0075] Components 38 and 40 are joined in a plane, said plane including a longitudinal axis L and / or coinciding with or extending parallel to a plane including the longitudinal axis L and axis P (see...). Figure 1 For example, components 38 and 40 may define a form fit and / or a force fit. For example, components 38 and 40 may be mechanically locked to each other and / or may be connected to each other by a snap-fit ​​connection. When connected, the components are positioned between the components (see also discussed below). Figure 9 The assembly 38, 40 may include a portion of the airflow regulator 22 (and, for example, support the airflow regulator). That is, each of the assemblies 38, 40 may include a section of the bearing surface for each of the airflow regulators 22.

[0076] like Figure 2 As shown, the airflow guiding element 20 is typically empty, or in other words, hollow. Therefore, the airflow guiding element houses a portion of the airflow regulator 22 within its hollow interior.

[0077] The airflow regulator 22 includes blades 42 and 44 in each air passage section 28, 30. Figuratively speaking, blades 42 and 44 can be considered as defining a large blade interrupted by the airflow guiding element 20. Typically, the air guiding element 20 is arranged and / or housed between blades 42 and 44.

[0078] In addition, such as Figure 6 As shown, blades 42 and 44 are connected by a connecting portion 46. This connecting portion 46 serves as and / or includes a pivot axis supported by components 38 and 40 of the air guiding element 20. Furthermore, the connecting portion 46 is housed within the hollow interior of the air guiding element 20. The connecting portion 46 also includes a connecting portion 48, which is also housed within the hollow interior of the air guiding element 20. A moving mechanism (not shown) can be coupled to said connecting portion 48 to pivot the airflow regulator 22 about the pivot axis P.

[0079] Blades 42 and 44 are both plate-like members. The blades extend between one of the air guiding surfaces 32 and 34 and the respective opposing inner surfaces 36 of the housing 12. Preferably, the blades contact at least one of the respective surfaces 32 and 34 and the inner surface 36. Blades 42 and 44 are both upright and extend along the pivot axis P. Therefore, the blades can be oriented such that the longitudinal axis L of the air guiding element 20 extends perpendicular to the blades 42 and 44, and / or wherein the airflow axis A extends parallel to the blades 42 and 44.

[0080] Return to reference Figure 1 The airflow guiding element 20 defines a step 21 in each of the air guiding surfaces 32, 34 (see also) Figure 2 Alternatively, only the air guiding surfaces 32, 34 may have corresponding steps 21. The steps 21 define a height difference or height in each of the air guiding surfaces 32, 34 relative to adjacent portions of the air guiding surfaces 32, 34. As described in further detail below, the adjacent portions are formed by recesses 50 in the air guiding surfaces 32, 34.

[0081] Each recess 50 is formed by an assembly 40 of the air guiding element 20 facing the air outlet 18. A step 21 extends along the entire length of the assembly 38. The step has a planar front extending perpendicular to the airflow axis A. In the illustrated embodiment, the step 21 serves as a stop element for the pivoting movement of each airflow regulator 22.

[0082] refer to Figure 6Blades 42 and 44 have a shape that takes into account the step 21. In particular, blades 42 and 44 also have a stepped configuration at their respective inner edges facing the opposing air guide surfaces 32 and 34. When viewed along the airflow axis A in the direction from air inlet 16 to outlet 18, blades 42 and 44 each include a first section 51 located in front of the step 21. Furthermore, each of blades 42 and 44 includes a second section 53 adjacent to the first section 51, located behind the step 21. The first section 51 further extends along the pivot axis P toward the opposing guide surfaces 32 and 34 (see also...). Figure 2 Note that the corresponding other edges opposite to the inner edges of blades 42, 44 face and preferably contact the inner surface 36 of housing 12.

[0083] As the blades 42, 44 pivot about the pivot axis P, segments 51, 53 of each blade move along angular segments and / or according to a partially circular stroke. In the assembly 40 of the air guide element 20 facing the air inlet 16, the corresponding stroke of the first segment 51 is accommodated by providing recesses 50. Recesses 50 are formed as flat portions that locally reduce the extension along the pivot axis P of the air guide element 20. In other words, recesses 50 define a local indentation along the pivot axis P in each of the first guide surface 32 and the second guide surface 34. In the example shown, recesses 50 are separated by portions 52 that define the recess (e.g., forming its edges). These portions 52 define a continuation of the curvature of the corresponding first air guide surface 32 and the second air guide surface 34, for example, when viewed from the air inlet 16 along the airflow axis A.

[0084] Each boundary portion 52 has a curved surface 58 that resembles the shape of the movement path of the corresponding adjacent outer edges of the blades 42, 44 when pivoting. Alternatively, there may be only one continuous recess 50 extending along the longitudinal axis L without being interrupted by any boundary portion 52.

[0085] exist Figure 9 In the image, step 21 can be seen again, which defines a height difference at least in the region of recess 50, as described above. Optionally, the boundary portion 52 defining recess 50 locally extends beyond the extension of step 21 along the pivot axis P, i.e., protrudes relative to step 21. This helps to smoothly guide airflow through step 21.

[0086] from Figure 9As can be seen again, both components 38 and 40 include a portion of the bearing surface of the bearing region 57 for receiving and supporting the airflow regulator 22. In the example shown, each of components 38 and 40 includes approximately half of a corresponding circular bearing region 57, which is configured to receive the shaft of the connecting portion 46 of each airflow regulator 22 (see [link to example]). Figure 6 ).

[0087] refer to Figure 10 It can be seen that the first section 51 of the airflow regulator 22 is accommodated in the recess 50 (in Figure 2 (Only some recesses are marked with separate reference numerals in the accompanying drawings). The first section 51 extends further than the step 21 toward the respective opposing blades 42, 44 and / or the respective opposing airflow guiding surfaces 32, 34. That is, the first section 51 protrudes further inward than the step 21 (e.g., toward the center of the airflow guiding element 20) and / or protrudes inward more than the step 21. Therefore, when pivoting about the pivot axis P, the first section 51 can abut against the corresponding adjacent section of the step 21. In this way, the pivoting range of the airflow regulator 22 can be defined and limited by the step 21. Moreover, a sealing effect is achieved between the contact portions of the step 21 and the blades 42, 44, which helps to prevent airflow from flowing out of the outlet 18.

[0088] Notice, Figure 9 and Figure 10 The configurations discussed are in Figure 7 and Figure 8 This is also quite evident. These figures clearly show the location and extension of step 21 and the location and extension of recess boundary portion 52 (not each of these figures is labeled with a separate reference numeral). Figure 7 This is a view from air inlet 16 toward air outlet 18, and Figure 8 This is a reverse view from air outlet 18 toward air inlet 16.

[0089] Figure 7 and Figure 8 The airflow regulator 22 is also shown to include first and second protrusions 54, 56 on opposite sides of each of its respective blades 42, 44 (not each is labeled with a separate reference numeral in the figures). The protrusions 54, 56 extend substantially perpendicular to the pivot axis P. The protrusions are formed as flat but curved sections, for example, curved plates, curved surfaces, or curved ribs. The protrusions extend along one of the airflow guiding surfaces 32, 34 respectively, but maintain a certain distance from it.

[0090] Therefore, a gap 55 is formed along the pivot axis P between each protrusion 54, 56 and the air guiding element 20. The gap 55 may have the same size along the pivot axis P, and the size of the gap is generally determined to promote the Coanda effect, taking into account the expected airflow intensity.

[0091] The first protrusion 54 is positioned above the recess 50 and extends axially through the step 21 (see also...). Figure 11 The second protrusion 56 is positioned above the portion (or edge) 52 that defines the recess 50 (see also...). Figure 11 Each protrusion 54, 56 defines a gap 55 with a corresponding portion of the air guiding surfaces 32, 34 located below it. The surface of each protrusion 54, 56 facing the air guiding surfaces 32, 34 is curved, particularly according to the curvature of the air guiding surfaces 32, 34 in front of or behind the Coanda shape and / or similar to the step 21 (when viewed along the airflow axis A). This can be, for example, in... Figure 2 and Figure 6 I saw it in the middle.

[0092] like Figure 2 As shown, a portion of the airflow can thus flow between the protrusions 54, 56 and the airflow guiding element 20. The protrusions 54, 56 help to smoothly guide the airflow through the step 21 (and / or through the boundary portion 52 and / or the recess 50). This limits turbulence and thus limits noise or airflow loss.

[0093] from Figure 11 As can be seen, when viewed along the airflow axis A, each of the protrusions 54 and 56 overlaps with step 21. In other words, at least in the depicted neutral position of the airflow regulator 22 (where these protrusions may not redirect or at least not significantly redirect the airflow from air inlet 16), each of the protrusions 54 and 56 overlaps with the areas of the airflow guiding element 20 in front of and behind step 21. This relates to the direction of observation along the airflow axis A from air inlet 16 to air outlet 18. This large axial extension of protrusions 54 and 56 contributes to the airflow smoothing effect of the protrusions.

[0094] The operation of the air outlet device 10 will be discussed in further detail below.

[0095] Figure 2 The airflow regulator 22 is depicted in a neutral position, in which blades 42 and 44 extend substantially parallel to the airflow axis A. The airflow entering from the air inlet 16 does not significantly change its flow direction relative to the vertical plane as it flows along blades 42 and 44. The airflow distributor 24 also occupies a neutral position, in which it coincides with the airflow axis A.

[0096] exist Figure 3 In this configuration, the airflow distributor 24 pivots at the maximum possible angle A1 toward and contacts the upper surface of the housing 12. As noted, the upper passage section 28 is thus blocked, causing the airflow to be redirected upward as it flows past the air outlet device 10.

[0097] exist Figure 4 In this configuration, the airflow distributor 24 pivots at the maximum possible angle A2 toward and contacts the lower surface of the housing 12. As noted, the lower passage section 30 is thus blocked, causing the airflow to be redirected downwards as it flows through the air outlet device 10.

[0098] exist Figure 5 In the middle, the airflow distributor 24 is in a neutral position. On the other hand, the airflow regulator 22 pivots so that its blades 42, 44 contact the step 20. As shown, the airflow cannot pass through or across the blades 42, 44, so, for example, from the passenger's perspective, the airflow is shut off.

[0099] Figure 11 ( Figure 10 as well as Figure 7 and Figure 8 The neutral position of the airflow regulator 22 is shown again. Figure 12 and Figure 13 In this configuration, the airflow regulators pivot together due to their connection to a common moving mechanism (not shown). As a result, blades 42 and 44 extend to the airflow axis A at a greater angle C. Therefore, the blades redirect the airflow entering from air inlet 16 to the left side ( Figure 12 ) and right side ( Figure 13 It should be noted that in these pivoting positions, protrusions 54 and 56 still at least partially overlap with step 21 and / or boundary portion 52. Furthermore, in Figure 12 In each recess 50, a boundary portion 52 serves as a stop member to limit the pivoting movement of the airflow regulator 22 in a corresponding first direction from the neutral position. In a corresponding other direction from the neutral position, the pivoting movement is limited by the step 21.

[0100] Figure 14 The closed position of the airflow regulator 22 is shown again. As shown, the blades 42 and 44 of adjacent airflow regulators 22 slightly overlap each other along the longitudinal axis L. This, combined with the contact formed with the step 21 (see...), Figure 5 This will reliably shut off the air flowing out through air outlet 18.
