Description

[0001] The invention relates to an air outlet, also called a fresh air grill, with adjustable air outlet direction according to the preamble of claim 1.

[0002] Air vents can be used, for example, in vehicles, especially motor vehicles, and generally serve to regulate the airflow exiting an air outlet in a horizontal and / or vertical direction. The air vent can, for example, be located in the instrument panel of a motor vehicle.

[0003] Besides the vehicle sector, such air outlets could also be used in fans, air conditioning systems, for example in buildings or other areas where the airflow can be specifically adjusted.

[0004] Various devices and methods for adjusting airflow are known in the prior art. In known air outlets, vertically and horizontally oriented air guide elements or louvers can be arranged one behind the other. Typically, an adjustment mechanism allows both the horizontally oriented and the vertically oriented louvers to be pivoted separately or together to adjust the direction of the outgoing air.

[0005] From DE 10 2021 119 416 A1, a control mechanism for a kinematic system in the vehicle interior is known. The control mechanism comprises a base body, a control cam, and at least two output elements. A cam element with two degrees of freedom relative to the base body is guided through the control cam by alternating movements in two opposite directions of the first degree of freedom, thereby successively coming into contact with the first and / or the second output element. To simplify the design of such a control mechanism, it is proposed that rotational movements be used instead of translational movements.

[0006] DE 10 2021 106 582 A1 describes a drive device for the independent control of at least two devices by means of a single drive unit, comprising at least one drive unit, a first transmission unit, at least one first guide element, and a first stationary control element, which has a first cam arrangement with a switching cam. The at least one first guide element is displaceable via the first transmission unit by the drive unit within the switching cam of the first cam arrangement, wherein at least one guide track is provided in the switching cam for each device to be controlled, in which at least one second guide element is arranged.The second guide elements are connected to first transmission elements rotatably mounted on the first stationary control element, which can be set into rotation according to the displacement of the at least one first guide element via the second guide elements, wherein the first transmission elements are each connected or connectable to the devices assigned to them.

[0007] For example, an air outlet for a motor vehicle is also known from DE 10 2018 005 002 A1.

[0008] DE 10 2015 101 254 B3 relates to a drive device for adjusting at least two devices.

[0009] From DE 10 2020 101 678 A1, an actuating device for changing a mass flow in a motor vehicle is known.

[0010] From DE 10 2014 203 511 B3 an air outlet with a control element is known, wherein the control element has a handle and a lever-shaped rotary element.

[0011] DE 10 2015 101 101 B3 relates to a drive device for adjusting at least two devices by means of a drive unit. The drive device further comprises a guide element, a transmission unit and a cam arrangement with several guide tracks.

[0012] From EP 3 628 891 A1, a guide arrangement with several guide tracks is known, which run at different levels and are arranged offset from each other in one plane. A guide cam is formed between the guide tracks, and the guide tracks have a rise towards the guide cam.

[0013] A disadvantage of the known air vents is their complex design with its elaborate kinematics.

[0014] Based on the disadvantages described above, the invention aims to provide an improved air outlet that has a simple design and allows for particularly convenient pivoting of the louvers in a space-saving and cost-effective manner.

[0015] This problem is solved with an air outlet according to claim 1. Advantageous embodiments and further developments of the invention can be found in the dependent claims.

[0016] The invention relates to an air outlet with adjustable air outlet direction, with a flow channel arranged in a housing, which has an air inlet opening and an air outlet opening substantially opposite the air inlet opening.

[0017] The air outlet is also referred to as a nozzle or air nozzle, whereby the flow channel does not necessarily have to have the shape of a classic nozzle with a narrowing flow cross-section. In particular, it is possible, in the installed position of the air outlet, to deflect the air jet both vertically and horizontally using a single actuator.

[0018] An airflow can enter the flow channel through the air inlet opening and exit through the air outlet opening.

[0019] Furthermore, at least one first lamella, for example a horizontal lamella, which can be pivoted about a first pivot axis relative to the flow channel, is provided for guiding the airflow, and at least one second lamella, for example a vertical lamella, which can be pivoted relative to the flow channel, is provided, the second pivot axis of which runs obliquely or perpendicularly to the first pivot axis.

[0020] This means in particular that the first pivot axis runs perpendicular to an imaginary or virtual plane, while the second pivot axis runs obliquely or parallel to the plane or lies in the plane.

[0021] The at least one first lamella is pivotable, for example, in a first pivoting range between two end positions that define the pivoting range. The at least one second lamella is pivotable, for example, in a second pivoting range about the second pivoting axis relative to the flow channel between two end positions.

[0022] For independent adjustment of the slats, a single drive, preferably electric or manual, and a coupling device are provided. The drive can preferably be designed as an electric actuator or an electrically operated actuator, for example, as an electric motor. Alternatively, it can also be designed as a manually operated knurled wheel, lever, sliding lever, or rack and pinion.

[0023] In other words, both the at least one first slat and the at least one second slat can be pivoted around the respective pivot axes by means of the drive, and thus, for example, electrically or by an electric motor, or manually, so that the slats, which are preferably inherently rigid or dimensionally stable, can be adjusted, i.e., pivoted, particularly conveniently and, in particular, automatically, for example, by means of a control system.

[0024] Since the first louver and the second louver, or the rows of louvers, can be driven and thus pivoted via the coupling device, and since the louvers can be pivoted relative to each other via the coupling device, different air outlet directions can be set, into which the air can flow out of the flow channel and, for example, into the interior of the vehicle or into a building.

[0025] According to the invention, the coupling device comprises a sliding cam operatively connected to the drive and slidably mounted relative to the housing of the air outlet. The sliding cam has a first control cam for adjusting different positions of the first louvers and a second control cam for adjusting different positions of the second louvers, the control cams being formed on different sides or surfaces of the sliding cam. Due to the large length of the control cams, finer adjustment of the air outlet opening is possible. It is conceivable that the drive acts directly, i.e., immediately, on the sliding cam.

[0026] The term "different sides of the sliding cam" means that the control curves are located on different surfaces of the sliding cam.

[0027] It is conceivable, for example, that the control cams are arranged on opposite sides or surfaces of a sliding cam that is essentially plate-shaped. "Plate-shaped" means that the sliding cam extends essentially in two dimensions.

[0028] Alternatively, the side of the sliding cam with the first control cam for setting different positions of the first slats can be inclined, in particular essentially perpendicular, to the side of the sliding cam with the second control cam for setting different positions of the second slats.

[0029] In particular, the sliding element can be essentially L-shaped. It is also conceivable that one side or surface with one of the control curves is arranged essentially perpendicular to the side with another control curve, without the sliding element itself being L-shaped. In these two variants, the side of the sliding element with the first control curve is oriented essentially perpendicular to the side of the sliding element with the second control curve. This particular design allows for optimization of the installation space within the air outlet. This is because the sliding element not only extends essentially in two dimensions, but also into another plane, in order to optimally utilize the available space there as well.

[0030] The different sides or surfaces for the control curves can be formed in one piece.

[0031] The airflow exiting the air outlet, particularly from the flow channel, is directed or deflected by means of the louvers in a particularly advantageous and, in particular, demand-oriented manner. The air outlet according to the invention enables the realization of a nozzle kinematics which has a particularly simple and therefore space-saving and cost-effective design and at the same time enables a particularly advantageous deflection of the airflow exiting the air outlet.

[0032] In this way, effective and targeted airflow control is achieved with just a few components. This also allows for precise maintenance of specific louver positions.

[0033] According to a further advantageous embodiment of the invention, a first control lever coupled to the first lamellae has a first guide pin which can be displaced in the first control curve to pivot the first lamellae about the first pivot axis relative to the flow channel.

[0034] Alternatively or additionally, it can be provided that a second control lever coupled to the second slats has a second guide pin which can be displaced in the second control cam to pivot the second slats around the second pivot axis relative to the flow channel, wherein, in the event of a displacement of the sliding cam caused by the drive, the guide pins coupled to the control levers are displaced in the respective control cams in such a way that both the first and the second slats can be adjusted independently of each other by means of a single drive.

[0035] Although the first and second slats are mechanically coupled to the single drive via the coupling device, the shape of the control cams allows them to be adjusted independently. For example, the first slat can be pivoted while the second slat remains in one position. This is achieved through a so-called free play in the control cam, during which the slat's position does not change.

[0036] In this way, a simple mechanical coupling of the slats with the corresponding control levers and the respective control cam is achieved. The guide pins are displaced within the two control cams when the cam disk moves or rotates, so that the control levers coupled to the guide pins are also moved accordingly. Consequently, the slats coupled to the control levers are also moved according to the displacement of the guide pins within the control cams. The control cams actuate the first and second slats simultaneously and independently of each other in a specific or predetermined relationship.

[0037] To achieve particularly simple and precise adjustment, according to an advantageous embodiment of the invention, at least one of the control levers is pivotably mounted by means of a bearing, so that when the corresponding guide pin is moved within the respective control cam, the control lever and the louvers coupled to it pivot. In this way, the movement of the guide pins within the control cams, and thus the movement of the control levers, is guided particularly efficiently and reliably. The bearing can be provided on a housing part of the air outlet that receives the louvers, so that the control lever (and the louvers) is pivotably mounted relative to this housing part.

[0038] In a particularly advantageous embodiment of the invention, it is provided that by means of the sliding cam driven by the drive, one of the first or second lamellae can be pivoted about its pivot axis relative to the flow channel and relative to the other lamella, while a pivoting of the other lamella about its pivot axis relative to the flow channel and caused by the drive is omitted.

[0039] This means in particular that, for example, the first lamella can be pivoted around the first pivot axis relative to the flow channel by means of the drive, while a pivoting of the second lamella around the flow channel by means of the drive and around the second pivot axis does not occur.

[0040] Alternatively or additionally, it is conceivable that the second lamella can be pivoted around the second pivot axis relative to the flow channel by means of the drive, while a pivoting of the first lamella around the first pivot axis by means of the drive does not occur.

[0041] This allows the airflow to be guided or directed particularly advantageously by means of the louvers, even though the louvers can be coupled or connected to the single drive common to the louvers via the coupling device.

[0042] Since both the at least one first lamella and the at least one second lamella can be pivoted by means of the one drive common to the lamellae, the number of parts, the installation space requirement, the weight and the cost of the air outlet can be kept within a particularly low range.

[0043] Of course, in accordance with the invention, it is also conceivable that the lamellae can be pivoted together or simultaneously around the pivot axes relative to the flow channel, for example by means of the drive via the coupling device.

[0044] According to an advantageous embodiment of the invention, at least one of the control levers has a flexible end which is coupled to a driver provided on the lamellae, and in particular can be attached to the driver.

[0045] It has proven particularly advantageous that the flexible end has clamping areas for receiving the driver, which are pre-tensioned against each other in the assembly position by means of a spring element.

[0046] The spring element creates a spring-loaded connection between the control lever and the louvers. This prevents damage to the kinematics and drive mechanism in the event of unintended manual intervention directly affecting the louvers due to improper use, such as manually adjusting the louvers by a user (i.e., by touching and moving them). This also applies to inserting or removing fragrance containers, smartphone holders, or similar items from the air outlet louvers. The spring-loaded connection of the control lever to the louvers ensures a degree of play without causing damage to the kinematics.

[0047] Due to the spring-loaded coupling, the slats can be moved manually to a certain extent if used improperly. However, damage to the control levers, guide pins, control cams, and drive mechanism is prevented by the spring coupling.

[0048] According to an advantageous embodiment of the invention, it can be provided that an output shaft of the drive acts on an output gear which engages in a toothing on the slidably mounted sliding cam for moving the sliding cam to adjust the slats.

[0049] An advantageous embodiment of the invention is one in which the toothing of the sliding cam is designed as a rack for linear movement of the sliding cam. It is conceivable that the sliding cam and the rack are formed in one piece.

[0050] The sliding screen can be made of plastic, especially of low-friction plastic, or metal.

[0051] According to an advantageous embodiment of the invention, several first lamellae and / or several second lamellae are coupled together for synchronous movement.

[0052] The first lamella, for example, belongs to a first row of lamellae, which may include the first lamella as well as further lamellae or at least one further lamella. The lamellae of the first row of lamellae are arranged, for example, consecutively or one behind the other along a particularly straight first direction, whereby the preceding and following descriptions of the first lamella can readily be applied to the other, further lamellae of the first row of lamellae and vice versa.

[0053] Alternatively or additionally, at least one second lamella can belong to a second row of lamellae, which may include the second lamella as well as several further lamellae or at least one further lamella. The lamellae of the second row of lamellae are, for example, arranged consecutively or one behind the other along a second direction that runs obliquely or perpendicularly to the first direction and, in particular, is straight, whereby the preceding and following descriptions of the second lamella can readily be applied to the other, further lamellae of the second row of lamellae and vice versa.

[0054] In a particularly advantageous embodiment of the invention, the sliding cam is arranged above or below the air outlet in the assembly state; in particular, the sliding cam and the drive can be arranged in a common housing, which further simplifies the construction of the air outlet.

[0055] Further objectives, advantages, features, and applications of the present invention will become apparent from the following description of an exemplary embodiment with reference to the drawing. All features described and / or illustrated, individually or in any meaningful combination, constitute the subject matter of the present invention, even independently of their compilation in the claims or their cross-references.

[0056] Some of these show schematically: Fig. 1. An air outlet with adjustable air outlet direction and a sliding screen in perspective view. Fig. 2 the air outlet according to Fig. 1 in another perspective view, Fig. 3 a detailed view of the air outlet according to Fig. 2 and Fig. 4 Another detailed view of the air outlet.

[0057] Identical or equivalent components are identified in the following figures of the drawing by reference numerals based on an embodiment, in order to improve readability.

[0058] Fig. Figure 1 shows an air outlet 10 with adjustable air discharge direction 9 in a perspective view. Also visible is a flow channel 1, which is arranged in a housing of the air outlet. The flow channel 1 has an air inlet opening 2 and an air outlet opening 3 that is substantially opposite the air inlet opening 2.

[0059] The Fig. Figure 2 shows the air outlet 10 according to Fig. 1 in another perspective view, where a drive housing has been hidden and a front panel has been removed for better clarity.

[0060] The Fig. 3 and Fig. Figure 4 shows detailed views of the air outlet.

[0061] An airflow 15 flows through the air inlet opening 2 into the flow channel 1 and out through the air outlet opening 3 (see figure). Fig. 2).

[0062] Also from Fig. Several first lamellae 5, pivotable about a first pivot axis 4 relative to the flow channel 1, extend to guide the airflow 15. These lamellae 5 can also be referred to as horizontal lamellae.

[0063] Also, especially in Fig. 3, several second lamellae 7, pivotable relative to the flow channel 1, can be seen, the second pivot axis 6 of which runs approximately perpendicular to the first pivot axis 4 of the first lamellae 5. These lamellae 7 can be referred to as vertical lamellae in the present embodiment. In other words, the first pivot axis 4 runs perpendicular to an imaginary or virtual plane, with the second pivot axis 6 running approximately parallel to or lying in the plane.

[0064] In the present embodiment according to the Fig. 1 to 4 are several first lamellae 5 and / or several second lamellae 7 coupled together for a respective synchronous movement.

[0065] The first lamellae 5, for example, can be pivoted in a first pivoting range between two end positions that limit the pivoting range. The second lamellae 7 can also be pivoted in a second pivoting range around the second pivoting axis 6 relative to the flow channel 1 between two end positions.

[0066] For independent adjustment of the slats 5, 7, a single, in this case electric motor drive 8 or actuator and a coupling device 12 are provided in the present embodiment. However, a manual drive (not shown) is also conceivable, for example a manually operated knurled wheel, a lever, a sliding lever or a pull or rack.

[0067] In this way, both the first slats 5 and the second slats 7 can be pivoted by means of the drive 8 about the respective pivot axes 4, 6, so that the slats 5, 7, which are preferably inherently rigid or dimensionally stable, can be pivoted particularly conveniently and especially automatically, for example by means of a control system or controller.

[0068] According to Fig. 1-4 The coupling device 12 has a sliding cam 14 operatively connected to the drive 8 and slidably mounted with a first control cam 16 for setting different positions of the first slats 5. Furthermore, the sliding cam 14 has a second control cam 17 for setting different positions of the second slats 7. The sliding cam 14 can be made of plastic, in particular of low-friction plastic, or metal.

[0069] As can be seen from the Fig. As can be seen from 1-4, the control curves 16, 17 are formed on different sides or surfaces of the sliding cam 14.

[0070] In an embodiment not shown, the sliding cam 14 can be essentially plate-shaped, with the control cams 16, 17 arranged on opposite sides 22, 23 of the essentially plate-shaped sliding cam 14.

[0071] The embodiments according to the Fig. Figures 1-4 show a different variant. Here, side 22, or surface of the sliding cam 14, with the first control curve 16, is oriented essentially perpendicular to side 23, or surface of the sliding cam 14, with the second control curve 17. The sliding cam 14 can be essentially L-shaped. In this case, side 22, or surface, with the first control curve 16 for the first (horizontal) slats 5, is positioned approximately perpendicular to side 23, with the second control curve 17 for the second (vertical) slats 7. It is also conceivable that the control curves 16 and 17 are arranged in reversed positions on sides 22 and 23, respectively.

[0072] It is also possible for variants to be formed in which side 22 of the sliding cam 14 with the first control cam 16 for setting different positions of the first slats 5 is inclined to side 23 of the sliding cam 14 with the second control cam 17. In other words, the sides or surfaces with the respective control cams 16, 17 can also be aligned at any other, arbitrary angle to each other.

[0073] As from Fig. As further shown in Figure 1, an output shaft of the drive 8 acts on an output gear 21, which engages in a toothed section 11 on the slidably mounted sliding cam 14 for moving the sliding cam 14 to adjust the lamellae 5, 7. The toothed section 11 of the sliding cam 14 is designed as a rack on the sliding cam 14 for linear movement of the sliding cam 14. The sliding cam 14 and the toothed section (rack) 11 can be formed as a single piece.

[0074] The sliding gate 14 is shown here in its assembled state according to Fig. 4 is arranged above a housing of the air outlet 10. The drive 8 acts directly on the drive shaft 13 of the sliding cam 14. The drive shaft 13 can be inserted into a corresponding receptacle on the drive 8.

[0075] How in particular the Fig. As shown in Figure 1, the first 5 and / or second lamellae 7 are coupled to a respective control lever 18, 19 for actuating the lamellae 5, 7. In an embodiment not shown, at least one of the control levers 18, 19 can have a toothed connection between two lever arms of the control lever 18, 19, which can lead to a uniform force transmission.

[0076] The first control lever 18 coupled to the first lamellae 5 has a first guide pin 24, which is displaced in the first control curve 16 to pivot the first lamellae 5 about the first pivot axis 4 relative to the flow channel 1 (cf. Fig. 4).

[0077] In the selected embodiment, the second control lever 19 coupled to the second lamellae 7 has a second guide pin 25, which is displaced in the second control cam 17 to pivot the second lamellae 7 about the second pivot axis 6 relative to the flow channel 1 (see Fig. 3).

[0078] When the sliding cam 14 is displaced relative to a housing of the air outlet 10 by the drive 8, the guide pins 24, 25 coupled to the control levers 18, 19 are displaced in the respective control cams 16, 17 such that both the first 5 and the second lamellae 7 are adjusted independently of each other by means of a single drive 8.

[0079] In other words, movement of the sliding cam 14 by the drive 8 causes independent adjustment of the first and second slats 5, 7.

[0080] Although the first 5 and second slats 7 are mechanically coupled to the single drive 8 via the coupling device 12, the shape of the control cams 16, 17 allows the first 5 and second slats 7 to be adjusted independently of each other. For example, the first slat 5 can be pivoted while the second slat 7 remains in one position. This can be achieved by a so-called free travel in the control cam, during which the position of the slat does not change.

[0081] As the Fig. As further shown in Figure 4, the first control lever 18 for adjusting the first (horizontal) lamellae 5 is pivotally mounted by means of a bearing 26, so that when the corresponding guide pin 24 is moved in the first control cam 16, the control lever 18 and the lamellae 5 coupled to it pivot. It is also conceivable that the second control lever 19 or both control levers 18, 19 are pivotally mounted by means of a bearing 26.

[0082] The bearing 26 can be provided on a housing part of the air outlet 10 that receives the lamellae 5, 7, so that the control lever 18, 19 (and the lamellae 5, 7) is designed to pivot relative to this housing part.

[0083] In particular, it is possible that by means of the sliding cam 14 driven by the drive 8 one of the first or second lamellae 5, 7 is pivoted about its pivot axis 4, 6 relative to the flow channel 1 and relative to the other lamella 7, 5, while a pivoting of the other lamella 7, 5 about its pivot axis 6, 4 relative to the flow channel 1 and caused by the drive 8 does not take place.

[0084] The louvers 5, 7 can thus be moved independently of each other into numerous positions in order to create an airflow 15 in almost any desired direction. Different air outlet directions can therefore be set, allowing the airflow 15 to exit the flow channel 1 and, for example, flow into the interior of the vehicle or into a building.

[0085] Of course, in accordance with the invention, it is also conceivable that the lamellae 5, 7, for example by means of the drive 8 via the coupling device 12, are pivoted together or simultaneously about the pivot axes 4, 6 relative to the flow channel 1.

[0086] In other words, a displacement of the sliding cam 14 by the drive 8 causes independent adjustment of the first and second slats 5, 7. In this way, a wide range of adjustment options is ensured.

[0087] As in particular the Fig. As can be seen from Figure 4, the first control lever 18 has a flexible end 27 which is coupled to a driver 28 provided on the first (horizontal) lamellae 5. The end 27 can be attached to the driver 28. However, it is also conceivable that the second control lever 19 or both control levers 18, 19 have such an end.

[0088] In particular, in the present embodiment it is provided that the flexible end 27 of the first control lever 18 has clamping areas 30 for receiving the driver 28 of the first lamellae 5, which are pre-tensioned against each other in the assembly position by means of a spring element 29.

[0089] This spring element 29 provides a spring-loaded coupling of the first control lever 18 to the first slats 5. In this way, in the event of unwanted manual intervention directly affecting the slats due to improper use, such as manual adjustment of the slats by a user (i.e., by touching and moving the slats), damage to the kinematics and the drive is prevented. Because of the spring-loaded coupling, while the slats can be moved manually to a certain extent in the event of improper use, damage to the control lever 18, the guide pin 24, the control cam 16, and the drive 8 is prevented by the spring coupling.

[0090] How Fig.As illustrated in Figure 1, the sliding cam 14 can be positioned above (or below) the air outlet 10 in the assembled state. In this case, the sliding cam 14 and the drive 8 are arranged in a common housing, which further simplifies the design of the air outlet 10.
