Description

The invention relates to an air outlet unit for vehicle ventilation according to the features of the preamble of claim 1.

From the prior art, as in the DE 20 2013 105 787 U1 described, a device for actuating assemblies with a cylindrical body known. The device, in particular for assemblies to be mounted in a passenger compartment of motor vehicles, comprises a housing and a pivotally mounted therein aperture or a cylindrical body which is mounted in the housing such that by rotating the cylindrical body, the relative position between different functional portions of the cylindrical body or the aperture and a viewing aperture in the housing or a frame provided thereon is changeable. On a bearing side of the cylindrical body acts a motorized rotary drive, which is controllable via actuators on the front side of the housing or on a frame surrounding the housing or set thereof on a surface element of the inner lining of the passenger compartment in one or the other direction of rotation. On the panel or the cylindrical body acts a spring accumulator in the region of at least one bearing in a side wall of the housing, which is biased such that the rotary drive rotates in one and in the other direction of rotation against the force of the spring accumulator or with shooting start in one direction tensions the spring accumulator and relaxes again when the movement is reversed.

The invention is based on the object to provide an improved over the prior art air outlet unit for a vehicle ventilation.

The object is achieved by an air outlet unit for a vehicle ventilation with the features of claim 1.

Advantageous embodiments of the invention are the subject of the dependent claims.

An air outlet unit for vehicle ventilation, in particular for a heating and / or air conditioning device of a vehicle, which is provided in particular for ventilating, heating and / or air conditioning a vehicle interior, in particular a passenger compartment, comprises at least one control element, also referred to as adjustment, for influencing an air outlet from the air outlet unit and at least one actuator, also referred to as an actuator, for adjusting the at least one actuating element. Such an air outlet unit is also referred to as an air nozzle, air nozzle unit, ventilation nozzle or ventilation nozzle unit.

According to the invention, the at least one adjusting element is rotatably mounted in the air outlet unit about an axis of rotation extending at least substantially parallel to an air flow direction, in particular rotatably mounted relative to the axis of rotation, for example rotatably mounted on the fixed axis of rotation, or rotatable together with the axis of rotation arranged in the manner described stored, d. H. firmly connected to the rotatable axis of rotation or with a rotating on the axis of rotation axis body of the axis of rotation and rotatable together. In this case, the at least one adjusting element is adjustable, in particular within the air outlet unit, in particular within an air-flow-through interior of the air outlet unit, in particular within a housing of the air outlet unit. The at least one adjusting element is thus arranged in particular in the air outlet unit, d. H. in particular in the interior of the air outlet unit through which air flows, in particular within the housing of the air outlet unit. The air outlet unit, in particular its interior through which air flows, in particular the housing of the air outlet unit, advantageously has an at least substantially round cross-section.

The air flow direction is the direction in which the air flows through the air outlet unit, in particular before it changes its direction due to the influence of at least one element of the air outlet unit, in particular due to the influence of the at least one control element. The air flow direction is thus, in particular, a main flow direction or a basic flow direction of the air through the air outlet unit.

The solution according to the invention makes it possible, in particular, to adjust the air outlet unit, in particular an air outlet characteristic and / or air outlet direction, of the air outlet unit by means of the at least one actuator, so that no manual operation, in particular adjustment, is required.

The solution according to the invention in particular allows a simple construction with low demands on tolerances, haptics and appearance and with a few individual parts. This is in particular an advantage over previously known air nozzles, which have a plurality of manually adjustable guide elements, for example lamellae, in an outlet-side opening region, by means of which various air outlet directions can be adjusted by manual adjustment. These conventional nozzles exist, in contrast to inventive solution, made of many filigree items and must meet high demands on tolerance, feel and appearance.

Another disadvantage of these previously known nozzles is that they can not be achieved manually in the case of variable seating positions in the vehicle, in particular in vehicles capable of autonomous or at least partially automated driving. This problem is also solved by the inventive air outlet unit by the actuator adjustment, so that a manual accessibility is not necessary and thus use in any seating position is possible.

The solution according to the invention also achieves a similar pressure loss with respect to the air flowing through in each setting of the air outlet unit, in particular in each position of the at least one actuating element. In contrast, in conventional air nozzles the pressure losses are strongly dependent on the position of the slats.

Furthermore, a lower pressure loss is achieved by the solution according to the invention, since in the region of the outlet-side mouth of the air outlet unit advantageously no air guiding parts are present, because in particular the at least one adjusting element is advantageously arranged in the air outlet unit.

Furthermore, it is achieved by the solution according to the invention that only small flow noises occur.

In one possible embodiment, the at least one adjusting element is designed, arranged and adjustable by means of the at least one actuator such that it blocks an air outlet at least in certain areas in at least one position. As a result, the air outlet is specifically deflected in a different direction, which is not locked by the at least one control element.

In one possible embodiment, the at least one adjusting element is designed, arranged and adjustable by means of the at least one actuator that it at least partially displaces an air flow in at least one position, in particular displaced in the direction of a central outlet region of the air outlet unit. As a result, in particular for setting different air outlet directions, the principle of local flow displacement by means of a control air flow is used.

The at least one adjusting element has, for example, at least one circular segment-shaped, circular sector-shaped, annular-sector-shaped or crescent-shaped positioning section. As a result, a corresponding region of the in particular round cross-section of the air-flow-through interior of the air outlet unit can be covered, and thus a corresponding air flow, in particular air outflow characteristic and air outflow direction, can be achieved.

The air outlet unit has, for example, a central air flow area and a peripheral air flow area enclosing the central air flow area on the periphery. The edge-side air flow region is designed in particular as an air flow channel, in particular between the housing and an inner wall arranged in the interior of the air outlet unit and radially spaced from the housing. In this case, it can be provided that an air flow which flows through the central air flow region is influenced by influencing, in particular deflecting, by means of the at least one control element an air flow which flows through the peripheral air flow region, thereby influencing the air flow of the central air flow region.

The at least one adjusting element is for example designed, arranged and adjustable by means of the at least one actuator that at least partially blocks the air outlet from the peripheral air flow region or at least partially displaces the air flow from the peripheral air flow region, in particular in the direction of the central outlet region repressed. As a result, the above-mentioned respective advantages are achieved.

The air outlet unit has, for example, a centered air displacement element. As a result, the air is displaced in a targeted manner from the central air flow region in the direction of the edge-side air flow region, in which the air flow can be influenced by means of the at least one control element.

In one possible embodiment, the air displacement element is perforated. This also allows air to escape from the central airflow area.

For example, a cross section at an air outlet side of the air outlet unit is larger than at an air inlet side of the air outlet unit. As a result, flow changes, which result only from the presence of the components in the perfused interior space and the resulting reduction in the free flow cross section, are avoided.

The at least one actuator is designed, for example, as an electric motor, in particular as an electric stepper motor. As a result, in particular an exact adjustment of the at least one actuating element and thus the outflow direction and Ausströmcharakteristik is possible. However, other configurations of the actuator are possible as an alternative. For example, the actuator may alternatively be designed as a pneumatic or hydraulic actuator.

The air outlet unit, which, as already mentioned above, is in particular a component of a corresponding device of a vehicle, in particular a heating and air conditioning system for ventilating and air conditioning a vehicle interior of the vehicle, thus has the at least one actuatorally adjustable control element, in particular for the automatic adjustment of different Air outlet directions by means of at least one actuator. In this case, the at least one adjusting element, for example, is designed, arranged and adjustable by means of the at least one actuator such that it blocks the air outlet at least in certain areas in at least one position. In particular, has a directed to a vehicle interior downstream surface of the air outlet unit, d. H. an air outlet side of the air outlet unit, an outer, d. H. marginal, outflow, which can be partially blocked by the at least one rotatably mounted actuator.

In a further possible embodiment, the at least one adjusting element, as already described above, is configured, arranged and adjustable by means of the at least one actuator that it at least partially displaces an air flow in at least one position, in particular displaced in the direction of a central outlet region of the air outlet unit , In particular, at least one flow channel is formed between the housing and the inner wall, wherein the at least one actuating element discharges the air flowing out of at least one partial area of the at least one flow channel in the direction of the nozzle center, d. H. in the direction of the central flow area, displaced, so that different air outlet directions can be realized thereby.

As already mentioned, the air outlet unit has, for example, a centrally arranged and, for example, perforated air displacement element, in particular a displacement body. This air displacement element forms in particular a central region of the outflow surface.

For example, as mentioned above, the cross section at an air outlet side of the air outlet unit is larger than at an air inlet side of the air outlet unit. In particular, the cross section of the housing is larger than the cross section of an air supply duct, which supplies the air to the housing of the air outlet unit.

By means of the actuator, which is also referred to as an actuator, which is designed in particular as a stepper motor, in particular a simple rotational movement can be generated, so that the at least one actuating element is rotatable by means of this actuator in a respective position. The actuator can be arranged, for example, on the air displacement element designed as a displacement body, in particular integrated therein, d. H. be arranged therein. Alternatively, the actuator can be arranged at another position, for example on an outer side of the housing, and then, for example, via at least one force transmission element, for example a gear and / or a shaft, for example a flexible shaft, to which at least one actuating element is coupled.

In one possible embodiment, the at least one adjusting element and the air displacement element formed, for example, as a displacement body can be designed, for example, as a one-part and / or one-piece component. For example, the air displacement element designed in particular as a displacement body is designed to be integrated in the one-piece and / or one-piece actuating element.

In one possible embodiment, at least one second actuating element is provided. This second adjusting element is advantageously mounted rotatably in the air outlet unit, like the first adjusting element, about the axis of rotation extending at least substantially parallel to the air flow direction. It can be provided that the actuator is coupled to both adjusting elements, so that both adjusting elements are adjustable by the same actuator, in particular rotatable, in particular are rotatable about the common axis of rotation. Advantageously, the two adjusting elements are coupled via different ratios or ratios with the actuator, so that the two adjusting elements are rotatable by the drive of the actuator with a different angular velocity. Ie. it is a relative movement, in particular relative rotation, the two adjusting elements allows each other.

In one possible embodiment, the air displacement element designed in particular as a displacement body has a plurality of sheet-like formations which extend radially in the direction of the housing and thus protrude, in particular, into the edge-side outflow region. These sheet-like formations are for example distributed over a circumference of the air displacement element such that they are spaced from each other. The at least one adjusting element likewise comprises a plurality of sheet-like formations, which, for example, are likewise distributed around a central circumference of the adjusting element such that they are spaced apart from one another.

By adjusting the adjusting element, the sheet-like formations of the air displacement element and the adjusting element can be arranged one behind the other in the air flow direction, whereby the air can flow between the circumferentially adjacent respective sheet-like formations, or offset from one another, so that they are completely or interstices between the sheet-like formations of the air displacement element are partially closed by the sheet-like formations of the actuating element, so that the air flow is reduced.

Furthermore, it can be provided that the actuating element less sheet-like formations than the air displacement element, wherein these are arranged such that in each position of the actuating element always at least one space between two adjacent sheet-like formations of the air displacement element is not covered by the control element. In this way, a direction adjustment of the outflowing air is made possible. For example, the actuator may also have only a sheet-like shape, so that in each case only a gap between two sheet-like formations of the air displacement element can be covered by the actuator.

In one possible embodiment it can be provided that the at least one adjusting element has at least one perforated area. This can be, for example, a central region of the control element. The perforated region may be, for example, a perforated plate, a ventilation grille or an otherwise air-permeable element. As a result, in particular in connection with the perforated region of the air displacement element, an air flow setting can be changed from the central air flow region. If the at least one adjusting element is adjusted in such a way that the perforations in the adjusting element and in the air displacement element overlap, air can flow out. If the adjusting element is adjusted such that the perforations deviate from one another, the central air flow region is closed.

Alternatively to the air displacement element may be arranged at the downstream end of the inner wall, a ventilation grille, a perforated plate or other air-permeable element, so that the same effect can be achieved. It can also be achieved depending on the position of the at least one control element different air permeability.

Alternatively or additionally, for example, at least one edge-side section of the at least one adjusting element can be designed correspondingly perforated, for example, the circular segment-shaped, circular sector-shaped, annular sector-shaped or crescent-shaped adjusting section. It can also be provided two or more such sections.

In one possible embodiment it can be provided that a flap is arranged in the middle region of the outflow surface. In particular, the air displacement element may be formed as such a flap. This flap can be opened and closed by an actuator, advantageously also actorisch actuated, for example by the already mentioned actuator or another actuator.

A vehicle ventilation, d. H. A ventilation device for a vehicle may include one or more such air outlet units. A vehicle expediently has such a vehicle ventilation. It can be provided that the air outlet unit to the vehicle interior through a ventilation grille, also referred to as Düsenabdeckgitter is laminated. This ventilation grille may have a corresponding optical appearance. It can be provided that the at least one perforated region, in particular the perforated central region and / or the at least one perforated edge-side section of the at least one control element cooperates with this ventilation grille such that different air permeabilities are formed depending on the position of the at least one control element. Ie. it may, as already described similarly above, overlap the perforations of the control element and the ventilation grille, so that an air outflow is possible, or by adjusting the at least one control element, the perforations of the ventilation grille and the at least one control element offset from each other, whereby the Airflow is blocked or at least reduced.

Alternatively or in addition to this ventilation grille, for example, the respective air outlet unit itself may have such a ventilation grille, perforated plate or other air-permeable element, in particular in the region of the downstream end of the flow channel, which cooperates with the at least one perforated region of the at least one actuating element in the manner described above, that depending on the position of the actuating element different air permeabilities are formed.

When the vehicle ventilation can be provided that a plurality of air outlet units can be arranged side by side. It may be provided in one possible embodiment that these air outlet units have a common actuator, ie that the actuator is associated with the plurality of air outlet units. For example, the axes of rotation of the air outlet units are kinematically coupled by gears or otherwise. In this case, the actuator can drive, for example, one of the axes of rotation and the at least one adjusting element arranged thereon directly, and the other axes of rotation with their adjusting elements are likewise driven via this kinematic coupling by means of the actuator.

In a method for operating the at least one air outlet unit, it may be provided, for example, that the at least one actuating element, driven by the actuator, performs a continuous rotary movement, which in particular leads to time-varying air outlet directions. As a result, an air movement in the vehicle interior that is perceived as activating and / or revitalizing can be achieved.

In the method for operating the at least one air outlet unit, in particular for venting the vehicle interior, in particular a respective outflow direction, in particular air outlet direction, automatically adjusted by means of at least one actuating element driven by the actuator. In particular, depending on one or more seating positions and / or seating orientations by the actuator, i. H. Actuator-driven adjustment of the at least one adjusting element automatically sets a suitable outflow direction, in particular an air outlet direction.

It can be provided that a person-specific optimal air outlet direction is determined by means of self-learning algorithms of artificial intelligence and is set automatically by a corresponding adjustment of the at least one control element by means of the actuator.

In one possible embodiment, a voice control of the at least one air outlet unit is provided, so that their adjustment, in particular the adjustment and thus adjustment of the at least one control element and thereby a respective adjustment of an air outlet direction and Luftausströmcharakteristik, can be activated by the voice control. If the vehicle ventilation system has a plurality of such air outlet units, it can be provided, for example, that each air outlet unit can be controlled individually, in particular by voice control, and / or that several or all air outlet units can be controlled jointly, in particular by voice control.

In one embodiment, the air outlet unit, as an alternative or in addition to the at least one rotatable control element, at least one inflatable actuator for flow displacement and / or obstruction of the air flow, in particular the flow channel on.

In one embodiment, the air outlet unit, alternatively or in addition to the at least one rotatable control element, in the region of the nozzle orifice, d. H. in the region of the air outlet side, one or more deformable adjusting elements for flow displacement and / or obstruction of the air flow, in particular of the flow channel.

Corresponding parts are provided in all figures with the same reference numerals.

The 1 to 19 show a variant and the 20 to 50 another variant of an air outlet unit 1 for a vehicle ventilation, in particular for a heating and / or air conditioning device of a vehicle, which in particular for ventilating, heating and / or air conditioning of a vehicle interior FR , In particular, a passenger compartment of a vehicle is provided. The vehicle ventilation system has at least one such air outlet unit 1 on, advantageously, a plurality of such Luftauslasseinheiten 1 , The respective air outlet unit 1 is in particular connected to an air supply line of the vehicle ventilation.

Such an air outlet unit 1 is also referred to as an air nozzle, vent, air nozzle unit or vent nozzle unit. Conventional air nozzles can only be adjusted manually by vehicle occupants. By such an adjustment, it is possible, in particular an air outlet direction AR to suit personal needs. Such manually adjustable air nozzles are usually made of many individual components such as slats, drivers, handles or different kinematic elements for manual adjustment. Furthermore, demands on tolerances, haptics and / or design are very high.

In contrast, in the following one in the 1 to 50 exemplified air outlet unit 1 described, which in particular aktorisch, ie by means of at least one actuator 2 , also referred to as an actuator, is adjustable. The air outlet unit 1 is, for example, laminated behind a ventilation grille 3 , For example, a designer grid, arranged and thus not visible to a vehicle occupant and in particular not manually adjustable.

Such lamination and the elimination of manual operation opens up new possibilities, with a simple design, the setting of an air outlet characteristic, in particular the air outlet direction AR to effect. For an autonomous or semi-automated driving operation of the vehicle provides an actuator adjustable air outlet unit 1 the advantage that an adjustment is possible even if due to a set seating position, for example, turned back seats, the air outlet units 1 no longer be reached manually.

The here described, in particular aktorisch adjustable, air outlet unit 1 therefore comprises at least one actuator 4 , Also referred to as adjustment, for influencing an air outlet from the air outlet unit 1 , in particular for influencing the air outlet direction AR and / or air outlet characteristic, and the at least one actuator 2 for adjusting the at least one actuating element 4 , In particular, this is at least one actuating element 4 around one at least substantially parallel to an air flow direction DR extending axis of rotation A in the air outlet unit 1 rotatably mounted.

The at least one control element 4 is especially within the air outlet unit 1 adjustable, in particular within an air-flow-through interior of the air outlet unit 1 , in particular within a housing 5 the air outlet unit 1 , The at least one control element 4 is thus in particular in the air outlet unit 1 arranged, ie in particular in the air-flowed interior of the air outlet unit 1 , especially within the housing 5 the air outlet unit 1 , The air outlet 1 , In particular, the air flowed through the interior, in particular the housing 5 the air outlet unit 1 , Advantageously, has a, at least substantially, round cross-section.

The air flow direction DR is the direction in which the air is the air outlet unit 1 flows through, in particular before they due to the influence of at least one element of the air outlet unit 1 , in particular due to the influence of the at least one actuating element 4 , their direction changes. The air flow direction DR is thus in particular a main flow direction or basic flow direction of the air through the air outlet unit 1 therethrough.

Especially in the in the 1 to 19 illustrated variant of the air outlet unit 1 this is at least one control element 4 advantageously designed, arranged and by means of the at least one actuator 2 adjustable so that it blocks at least in some areas an air outlet at least partially. As a result, the air outlet is targeted in a different direction, which by the at least one control element 4 is not locked, deflected, and thereby a respective air outlet direction AR set.

In the 1 and 2 are in particular the basic elements of this first variant of the air outlet unit 1 shown. The 3 to 19 show in particular developments of this first variant of the air outlet unit 1 ,

Via an air duct 6 which is part of the heating and / or air conditioning device of the vehicle or, as shown here, part of the air outlet unit 1 may be air from the heating and / or air conditioning device of the vehicle of the air outlet unit 1 , in particular their housing 5 , fed. The air outlet unit 1 includes the housing 5 , opposite the air duct 6 has a larger cross-section. Ie. in particular an air outlet side AS of the housing 5 has a larger cross-section than an open air inlet side IT of the housing 5 ,

The air outlet unit 1 further comprises at the air outlet side AS and thus the vehicle interior FR facing a downstream surface 7 , which in its inner, ie central, region an air displacement element designed in particular as a displacement body 8th and in its outer, ie edge-side, region a free flow-through outflow area 9 in the case of a round cross-section of the air outlet unit 1 in particular designed as an annular gap. Ie. the air displacement element 8th is centered, in particular with respect to the cross section of the air outlet unit 1 centered, in the air outlet unit 1 , in particular in their housing 5 arranged.

In this outer outflow area 9 is due to the advantageously simple trained actuator 2 , For example, by an electric stepper motor, the at least one actuator 4 rotated, depending on the position of the actuator 4 the outflow direction, ie the air outlet direction AR , the air outlet unit 1 can be adjusted by that part of the outer outflow area 9 is blocked. The actuator 4 , in particular a parking section ST of the actuating element 4 , is in the example shown by struts 10 with the rotation axis A of the actor 2 connected. The 1 and 2 show an example of the actuator 4 in a lower position, whereby an upward outflow of the air is achieved.

With the air outlet unit described, it is thus possible by a simple, in particular by means of a single actuator 2 generated rotary motion the actuator 4 so position the air outlet direction AR for example, up, down, left or right is set. The 3 to 8th show different means of the actuator 2 set positions of the control element 4 and the resulting air outlet direction AR ,

The air outlet direction AR is by adjusting the control element 4 by means of the actuator 2 in particular continuously variable. Depending on which maximum outflow angle is to be achieved and / or which in the air outlet unit 1 generated pressure loss is maximum, geometric parameters, such as a cross section of the outflow 9 , a size of the air displacement element 8th and / or a size of the at least one actuating element 4 be selected accordingly. Furthermore, the air displacement element 8th for example, be perforated and thereby made permeable to air.

In the vehicle arranged state of the air outlet unit 1 is downstream of the air outlet unit 1 ie in the area of their air outlet side AS For example, the previously mentioned ventilation grille 3 provided for lamination, which, for example, as an air-permeable surface of an instrument panel 11 of the vehicle is formed. Altemative for training as a ventilation grille 3 are also other air permeable variants of this range of the instrument panel 11 possible.

The actor 2 is for example in the area of the air displacement element 8th or integrated in it, such as in the 1 to 9 shown. Alternatively, the actuator 2 for example, such as in the 18 and 19 and for the further variant in the 20 and 30 shown on an outside of the housing 5 be arranged and via a corresponding kinematics, for example via a gear and / or a shaft, for example via a flexible shaft, with the axis of rotation A to the drive and thus to drive the at least one control element 4 be coupled.

The 9 and 10 show a further embodiment of this variant of the air outlet unit 1 , The air outlet unit 1 here has two control elements 4 on, in 9 the two control elements 4 in the air flow direction DR are arranged one behind the other and in 10 the two control elements 4 in the circumferential direction of the air outlet unit 1 are arranged side by side. The two control elements 4 have a different size area, so that in 9 behind the front control element 4 arranged further control element 4 in the circumferential direction on both sides something about the front actuator 4 survives.

Both in the 9 and 10 shown positions and other positions of the two control elements 4 are advantageously adjusted by the fact that by corresponding not shown here kinematic elements, for example by a gear transmission, the two control elements 4 due to a different translation or reduction by the same actor 2 with different rotational speeds and thus are rotatable relative to each other. As a result, in particular, a neutral air outlet direction AR allows, as in 10 shown. Here is the edge discharge area 9 through the two control elements 4 completely closed, allowing air to pass through the perforated air displacement element 8th flows out, substantially straight, ie with respect to the air flow direction DR not distracted so that then the air outlet direction AR at least substantially the air flow direction DR equivalent. Through these two control elements 4 in particular, not only the air outlet direction AR can be adjusted, but also an opening size of the edge-side outflow area 9 and thus a strength and / or intensity of the air flow from this marginal outflow area 9 ,

Another simple embodiment of this first variant of the air outlet unit 1 has an in 11 shown one-piece actuator 4 on. Here is the air displacement element 8th no fixed component, but a component of the control element 4 , The actuator 4 and the air displacement element 8th are thus formed in one piece and / or in one piece, so that the air displacement element 8th together with the actuator 4 is rotatable.

With another in the 12 and 13 illustrated embodiment, the setting of a diffuse, distributed in all spatial directions outflow is also possible. This is made possible by the fact that the air displacement element designed in particular as a displacement body 8th several leaf-like formations 12 shown here four such leaf-like formations 12 , which extend radially in the direction of the housing 5 extend and thus in particular in the marginal outflow area 9 protrude. These leaf-like formations 12 are over a circumference of the air displacement element 8th distributed so that they are spaced apart, in particular evenly distributed.

The actuator 4 also includes several leaf-like formations 13 which likewise surround a central circumference of the control element 4 are distributed so that they are spaced from each other. In particular, the parking sections ST of the actuating element 4 each as such a sheet-like formation 13 educated.

By adjusting the control element 4 can the leaf-like formations 12 . 13 of the air displacement element 8th and the actuating element 4 in the direction of air flow DR be arranged one behind the other, whereby the air between the circumferentially adjacent respective sheet-like formations 12 . 13 can flow through, as in 12 shown, or offset from each other, so that the spaces between the sheet-like formations 12 of the air displacement element 8th completely or partially by the leaf-like formations 13 of the actuating element 4 are closed, so that the air flow is reduced, as in 13 shown.

It is provided here that the actuator 4 less leaf-like formations 13 has as the air displacement element 8th , here only three leaf-like formations 13 , Which are arranged such that in each position of the actuating element 4 always at least one space between two adjacent sheet-like formations 12 of the air displacement element 8th not by the actuator 4 is covered, as in 13 shown. In this way, a direction adjustment of the outflowing air is made possible.

In the in the 14 to 17 illustrated embodiment of this first variant of the air outlet unit 1 is the air displacement element 8th perforated, as in 14 shown. Likewise, a middle Stellelementbereich 14 of the actuating element 4 perforated, as in 15 shown. Advantageously, both hole patterns are the same.

In an in 16 shown first position of the actuating element 4 the two hole patterns are exactly above each other, so that a flow through the air displacement element 8th and the middle actuator area 14 and thus a central portion of the air outlet unit 1 is possible. By a slight rotation of the actuator 4 , as in 17 shown overlap the hole pattern such that the flow through the air displacement element 8th through the actuator 4 is locked and thus no flow through this central region of the air outlet unit 1 is possible.

By an adjustable in this way flow through the central region of the air outlet unit 1 is the size of the outflow angle of the air from the air outlet unit 1 adjustable. The flow angle becomes steeper, the less air passes through the central area of the air outlet unit 1 flows. By a continuous rotation of the control element 4 It is also possible, the air outlet direction AR to change periodically in temporal change and thereby perceived as activating and vitalizing temporally variable air movement, for example, similar to a fresh sea breeze in the vehicle interior FR to create.

Combinations of in the 9 to 17 shown embodiments are also possible.

In another in the 18 and 19 illustrated embodiment of the first variant of the air outlet unit 1 is the air displacement element 8th not as an air displacement body, but as a flap 15 formed, in the example shown with two to a transverse to the air flow direction DR extending pivot axis SA swiveling wings 16 , This flap 15 For example, by an actuator not shown here in an 18 illustrated closed position and in an in 19 illustrated open position and, for example, in one or more intermediate positions movable, whereby a central flow through the air outlet unit 1 allowed or prevented. This is for example an alternative to in the 14 to 17 illustrated embodiment. The actuating unit is advantageously a further actuator, for example an electrical actuator, in particular an electric motor, or a pneumatic or hydraulic actuator, so that this adjustment can also be made automatically.

In the in the 20 to 50 shown second variant of the air outlet unit 1 this is at least one control element 4 in particular designed, arranged and in particular by means of the at least one actuator 2 adjustable in that it displaces an air flow in at least one position at least partially, in particular in the direction of the central outlet region of the air outlet unit 1 repressed.

The at least one control element 4 has, for example, at least one circular segment-shaped, circular-sector-shaped, annular-sector-shaped or crescent-shaped positioning section ST on. As a result, a corresponding region of the in particular round cross section of the air-flow-through interior of the air outlet unit 1 covered and thus a corresponding air flow, in particular Luftausströmcharakteristik and air outlet direction AR , be achieved.

The air outlet unit 1 has, for example, a central air flow area For example, and a central airflow area For example, peripherally enclosing marginal air flow area RB on. The marginal air flow area RB is designed in particular as an air flow channel, in particular between the housing 5 and one in the interior of the air outlet unit 1 arranged and from the housing 5 radially spaced inner wall 17 , It should be provided in particular that an air flow, which the central air flow area For example, flows through, is influenced by means of the at least one actuating element 4 a control airflow SL , the marginal airflow area RB flows, is influenced, in particular deflected, and thereby the air flow of the central air flow area For example, affected.

The at least one control element 4 is for example designed, arranged and in particular by means of the at least one actuator 2 adjustable, that in at least one position, the air outlet from the peripheral air flow area RB at least partially blocks or the control air flow SL from the peripheral air flow area RB at least partially displaced, in particular in the direction of the central outlet region and thus in the direction of the air flow, which the central air flow area For example, flows through, displaces. The basic principle of this second variant of the air outlet unit 1 for setting different air outlet directions AR is used, that is the local flow displacement by means of the control air flow SL ,

The 20 to 27 show the basic elements of this second variant of the air outlet unit 1 , About an air duct, not shown in this second variant 6 which is part of the heating and / or air conditioning device of the vehicle or part of the air outlet unit 1 is air from the heating and / or air conditioning device of the vehicle air outlet 1 , in particular their housing 5 , fed.

The air outlet unit 1 includes the housing 5 which in the illustrated examples of the second variant, for example, has a substantially constant cross-section. In the case 5 and spaced radially inwardly from this is the inner wall 17 arranged. This is between housing 5 and inner wall 17 the air flow channel for the marginal air flow area RB educated.

Center of the control element 4 becomes the control airflow flowing through a portion of the air flow passage SL from the case 5 away towards the air outlet unit center, ie in the direction of the central air flow area For example, , displaced, whereby a flow impulse is achieved, by means of which the air outlet direction AR is changed. In the exemplary illustration according to the 20 and 21 is the actuator 4 , in particular the deflection of the control air flow SL serving adjusting section ST of the actuating element 4 , in a lower area of the air outlet unit 1 , causing a deflection of the air outlet unit 1 exiting air jet, ie a deflection of the air outlet direction AR , to the top.

By rotation of the actuator 4 around its axis of rotation A by the actor 2 can the air outlet direction AR the air outlet unit 1 be changed. There are, for example, air outlet directions AR upwards, downwards, to the left, to the right, to the upper left, to the upper right, to the lower left and to the lower right realizable, as in the 22 to 27 shown.

In the vehicle arranged state of the air outlet unit 1 is also in this second variant downstream of the air outlet unit 1 ie in the area of their air outlet side AS and thus in the mouth region of the air outlet unit 1 For example, the previously mentioned ventilation grille 3 provided for lamination, which, for example, as an air-permeable surface of an instrument panel 11 of the vehicle is formed. Alternatively to training as a ventilation grille 3 are also other air-permeable surfaces, in particular other air-permeable variants of this area of the instrument panel 11 , possible.

In this second variant and / or in the first variant of the air outlet unit described above 1 is the ventilation grille 3 or the other air-permeable surface, in particular as part of the instrument panel 11 , for example, optically adapted to a desired design language. So it may be desired, for example, that the ventilation grille 3 in its surface significantly larger than a mouth area, ie as the air outlet side AS , the air outlet unit 1 is trained.

The 28 and 29 show to the 20 to 27 alternative exemplary embodiments of the actuating element 4 , whereby different Ausströmcharakteristiken can be achieved. As already mentioned above, the adjusting section ST of the actuating element 4 , which in particular the deflection of the control air flow SL serves, for example, a circular segment, as in 28 shown, circular sector-shaped, circular sector-shaped, as in the 22 to 27 shown, or sickle-shaped, as in 29 shown. The at least one parking section ST is, as in the first variant, for example, about struts 10 with the rotation axis A coupled.

A further advantageous embodiment of this second variant of the air outlet unit 1 , by the larger exit angle of the air outlet direction AR can be achieved in the 30 to 37 shown. The actuator 4 here has two parking sections ST on, each by striving 10 with the common axis of rotation A are connected.

The parking sections ST lie opposite each other, with the first control section already described above ST in the manner already described the control air flow SL deflects and the other control section ST a partial region of the flow channel of the peripheral flow region RB blocked. By a downstream of this further Stellabschnitts ST forming negative pressure area becomes a partial air flow TL in this area also after diverted, in 30 to 32 illustrated example deflected upward, whereby the displacement effect of the control air flow SL is further supported and thus a particularly strong deflection of the air outlet direction AR , in this example up, can be realized. In addition, the obstruction of the flow channel of the peripheral flow region RB through the further control section ST of the actuating element 4 an amount of air of the control airflow SL increased, which also leads to a stronger deflection of the air outlet direction AR leads. In the 32 to 37 are different positions of the actuator 4 and resulting air outlet directions AR shown.

In another embodiment, the two control sections ST Components of two individual control elements 4 be, for example, which can be rotated at the same rotational speed by acting in the same way with the actuator 2 are coupled, or for example, as already described above to the first variant, with different rotational speeds are rotatable, in particular by means of the same actuator 2 , For example, by a corresponding translation or reduction, so that a change in a relative position of the two control sections ST is enabled to each other.

38 shows a further advantageous embodiment of this second variant of the air outlet unit 1 in which the actuator 4 in the middle area additionally an actuator ventilation grille 18 having. At the downstream end of the inner wall 17 is a central ventilation grille 19 arranged as in 39 shown.

Depending on the position of the control element 4 and thus belonging to this Stellelementlüftungsgitters 18 arise in interaction with the fixed central ventilation grille 19 different air permeabilities in the middle area of the air outlet unit 1 ie in the central air flow area For example, , whereby the momentum and / or the amount of air through this central air flow area For example, through changes. With high air permeability of the ventilation grille 18 . 19 This results in a high air flow and due to its high momentum a lower beam deflection, ie a lower deflection of the air outlet direction AR , as in 39 shown. At low air permeability, however, results in a low flow of air through the central air flow area For example, and due to the low momentum, a higher beam deflection and thus a greater deflection of the air outlet direction AR by means of the control airflow SL , as in 40 shown.

In another embodiment, as in FIGS 41 and 42 shown, the actuator ventilation grille 18 near the particular for lamination of the air outlet unit 1 serving ventilation grille 3 arranged, ie in the region of the air outlet side AS , in particular in the mouth area, the air outlet unit 1 so that these two ventilation grilles 18 . 3 interact in the manner described above. In the interplay of these ventilation grilles 18 . 3 form depending on the position of the control element 4 the different air permeabilities with the above-described respective effect on the air outlet direction AR ,

In a further embodiment of the second variant of the air outlet unit 1 is at least one of the parking sections ST or are, as in the 43 to 45 shown, both parking sections ST formed perforated, for example, ventilation grille-shaped or perforated plate-shaped, and thus have a predetermined air permeability. In the area of the air outlet side AS is an outer ventilation grille segment at the edge 20 arranged, which with the parking section ST for deflecting the control airflow SL interacts. In the area of the outlet end of the inner wall 17 is between the inner wall 17 and the housing 5 an inner ventilation grille segment 21 arranged, which with the other control section ST of the actuating element 4 interacts. Is only one of these control sections ST formed perforated, it may be provided, for example, that only this perforated control section ST assigned ventilation grille segment 20 . 21 is available.

The respective perforated adjusting section ST and the respective assigned ventilation grille segment 20 . 21 form depending on the position of the control element 4 different air permeability, whereby either the control air flow SL and / or this opposite partial air flow TL can be influenced so that thereby different exit angles of the air outlet direction AR can be realized. This embodiment may for example be combined with the embodiment according to FIGS 38 to 40 in which the actuator 4 the actuator ventilation grille 18 having.

To the described principle of both the first and the second variant of the air outlet unit 1 For non-circular forms of Luftausströmern implement, for example, several Luftauslasseinheiten 1 be arranged side by side, whereby, for example, elongated Luftausströmer can be formed, as in 46 shown. It can be provided that a common actuator 2 for all air outlet units 1 used as such an air vent. For example, by the actuator 2 one of the axes of rotation A of the air outlet units 1 driven, in particular directly driven, and whose movement is, for example by means of gears and / or other kinematic elements, on the other axes of rotation A transfer. These are the axes of rotation A correspondingly coupled together, for example via the gears and / or other kinematic elements, so that the other axes of rotation A also by means of the actuator 2 be driven, in particular indirectly via the directly driven axis of rotation A.

Other embodiments, in particular for the formation of non-circular, for example quadrangular, air vents are in the 47 to 50 shown. Here, the air displacement takes place, in particular the deflection of the control air flow SL , and / or the obstruction of an area edge airflow area RB , in particular a region of the flow channel, for example by means of inflatable control elements 4 as exemplified in the 47 and 48 shown, or by deformable control elements 4 , for example Shape memory materials, as exemplified in U.S. Pat 49 and 50 shown.
