Description

[0001] The invention relates to an air outlet for a vehicle.

[0002] Such an air outlet is described in DE 10 2020 133 649 A1. It comprises a chamber into which an airflow is supplied via an air inlet, and the airflow is discharged into the vehicle interior via at least one air outlet. Two movable ventilation grilles with vertically and horizontally arranged louvers are associated with the air outlet. Each ventilation grille has a drive unit with an electric motor and a mechanical gearbox for pivoting the louvers.

[0003] The transmission comprises a first drive with a first drive gear, which is fixed on the motor shaft of an electric motor, and two axially movable output gears that are rotatably connected and axially spaced apart. This space corresponds to the width of a rack with which the output gears engage. The rack moves the clutch plates in one direction. All gears are helical.

[0004] When the drive gear moves in a first direction, the output gears are axially displaced against the force of a first spring, so that a first gear engages with the drive gear and engages with the rack. The rack is driven in a first direction. An opposite movement of the drive gear causes the output gears to be axially displaced in the opposite direction against the force of a second spring, so that the drive gear and the rack engage with a second output gear. The rack is driven in a second direction.

[0005] The second ventilation grille is moved by a similarly designed drive.

[0006] Furthermore, air outlets are described in JP 2005- 55 061 A, CN 111 055 658 A, DE 10 2018 005 002 A1 and US 2022 / 0 145 970 A1.

[0007] According to a first aspect, the object of the invention is to design an air outlet with a drive that enables a saving in the cost of parts as well as in the installation space.

[0008] The problem is solved by an air outlet having the features of claim 1.

[0009] The air outlet according to the invention is intended for a vehicle. For the purposes of the application, a vehicle is a land, air, or water vehicle. The air outlet comprises an air inlet, an air outlet, and at least one movable first functional device and one movable second functional device. The first functional device can, for example, be a first air deflector comprising at least one lamella whose longitudinal center axis is oriented approximately horizontally. The second functional device can, for example, be a second air deflector comprising at least one lamella whose longitudinal center axis is oriented approximately vertically.

[0010] A functional device is, for example, a device that provides certain functions of the air outlet and has at least one movable part that can be moved by a drive device of the air outlet.

[0011] The air outlet includes a drive device for powering the first and second functional devices. The drive device is equipped with a drive shaft that can rotate in opposite directions around a geometric drive axis, which drives a helical drive gear in opposite directions.

[0012] The air outlet further comprises a first output gear with helical teeth on a geometric first output axis of rotation and a second output gear with helical teeth on a geometric second output axis of rotation for driving the first and second functional devices of the air outlet. The drive gear is rotationally fixed to the drive shaft and is movable in directions parallel to the drive axis of rotation of the drive shaft. The movement of the drive gear with respect to a first direction of movement and with respect to a second direction of movement parallel to the drive shaft is limited by at least two stops. These stops are, for example, end stops of the movement. The drive axis of rotation and the output axes of rotation are, for example, parallel to each other.

[0013] The stopping mechanism for the respective output gears should be such that it prevents the output gears from rotating before the input gear moves into contact with the first or second stop and thus reaches its end position. This stopping mechanism can be achieved, for example, by a downstream mechanism or by stopping devices such as springs and / or dampers.

[0014] The air outlet according to the invention comprises a drive device with which at least one first functional device and a second functional device can be driven. More than two functional devices, e.g., three or four functional devices, can also be driven. According to the invention, the output rotary axes can be spaced apart from one another, which allows for a flexible design. The air outlet requires little installation space, and the number of parts is reduced compared to air outlets of the prior art.

[0015] The output gears are fixedly arranged, for example, parallel to the output axis of rotation. Each of the first and second output gears can be driven by the axial positioning of the drive gear. The direction of rotation of the drive gear determines whether it is positioned against the first or the second output gear. At least two stops position the drive gear so that it is engaged with either the first or the second output gear.

[0016] When the drive gear is engaged with the first or second output gear, it can also engage with and drive at least one additional gear. In this way, another functional device can be moved. The additional gear can, for example, be arranged in a plane formed by the respective output gear or in a plane perpendicular to the plane formed by the respective output gear.

[0017] The movement of the output gears relative to the output axis of rotation is restricted, for example, by friction materials. By restricting the output gears, a counterforce is generated to the force of the drive gear in the circumferential direction, against which the drive gear can brace itself for axial movement. In other words, the drive gear can screw itself along the output gears and move along the drive axis of rotation when the output gears are stationary due to a counterforce. If the counterforce is large enough, the drive gear will move quickly to the opposite stop when the direction of rotation of the drive axis is reversed.

[0018] For example, at least one first functional device is designed as an air deflection device with at least one movable vane, which can be driven by the first output gear. The air deflection device comprises, for example, at least one vane, in particular a plurality of vanes. The vane forms an air guide element to direct the airflow. For example, at least one second functional device is designed as an air deflection device with at least one movable vane, which can be driven by the second output gear.

[0019] The first louvers are arranged approximately horizontally and are designed to direct the airflow upwards in one end position, downwards in a second end position, and straight ahead in a middle position. Further intermediate positions may be present and can be selected as desired.

[0020] The second air deflector comprises, for example, at least one louver, and in particular a plurality of louvers. The second set of louvers are, for example, arranged approximately vertically and are suitable for directing the airflow to the right in a first end position, to the left in a second end position, and straight ahead in a middle position. Further intermediate positions may be present and are arbitrarily selectable.

[0021] The movement of the first air deflector and / or the second air deflector is such that the vanes of each air deflector are rotated synchronously by means of a synchronizing device. For example, each vane has a lever arm, and each lever arm is articulated to a drive bar. The drive bars are, for example, designed as racks, each of which meshes with an output gear.

[0022] The air outlet, for example, has a control device with which the drive mechanism can be controlled in such a way that the first and second air deflectors are set to the desired positions. As soon as the respective air deflector is in the desired position, the direction of the drive gear is reversed, for example. The other air deflector can then be set to the desired position.

[0023] A sensor device at the end stops could, for example, serve as a detector which transmits the lamella position to the control device depending on the direction of rotation of the drive wheel.

[0024] The air outlet, for example, has a control device which, in addition to or as an alternative design, allows the direction of rotation of the drive shaft to be manually controlled in one operating mode. In this case, the drive gear moves in a direction parallel to the axis of rotation, depending on the direction of rotation, to a stop and then drives the output gear with which it engages according to its position.

[0025] According to a second aspect, the invention relates to a vehicle interior with at least one air outlet.

[0026] The same state of the art applies here as in the first aspect of the invention.

[0027] The purpose of the invention was to create a vehicle interior with an air outlet with a drive that enables savings in the number of parts and the installation space.

[0028] The problem was solved by a vehicle interior comprising at least one air outlet according to the first aspect of the invention. Several of the aforementioned air outlets can be located, for example, in the dashboard, in the interior trim panels, or in the center console.

[0029] Exemplary embodiments of the invention are described in the following description of the figures, also with reference to the drawings. For the sake of clarity, identical or comparable parts, elements, or areas are designated with the same reference numerals, sometimes with the addition of lowercase letters, even where different embodiments are concerned.

[0030] Features described only in relation to one embodiment can also be provided in any other embodiment of the invention. Such modified embodiments are included in the invention, even if they are not shown in the drawings.

[0031] All disclosed features are essential to the invention. The disclosure of this application hereby incorporates in full the disclosure content of the cited publications and the described devices of the prior art, also for the purpose of including one or more features of these documents in one or more claims of the present application.

[0032] They show: Fig. 1a a perspective view of the air outlet, wherein a drive gear of the drive device is arranged in a first position, Fig. 1b a perspective view of the air outlet according to Fig. 1a, wherein a drive gear of the drive device is arranged in a second position, Fig. 2a a schematic view of the drive device of the air outlet according to Fig. 1b, Fig. 2b a schematic view of the drive device according to Fig. 1a, Fig. 3 a schematic representation of a second embodiment of the drive device of the air outlet, which corresponds in principle to the first embodiment, wherein the drive gear is arranged in a first end position and is in engagement with a first output gear, Fig. 4 the drive device according to Fig. 3, wherein the drive gear is arranged in an intermediate position and is engaged with a first output gear and a second output gear, Fig. 5 the drive device according to Fig. 1, wherein the drive gear is arranged in a second end position and is engaged with a second output gear, Fig. 6 the drive device in accordance with the previous Fig. 5, wherein the drive gear is arranged in the second end position and is engaged with a second output gear, wherein the drive gear is driven in a second direction of rotation, Fig. 7 the drive device according to Fig. 6, wherein the drive gear is arranged in an intermediate position and is engaged with the first output gear and the second output gear, Fig. 8 the drive device in accordance with Fig. 7, wherein the drive gear is driven in a second direction of rotation and is in engagement with the first output gear, Fig. 9 a schematic top view of a drive device of an air outlet according to a third embodiment, wherein planet gears are in a basic position out of engagement with the output gears, Fig. 10 a view based on Fig. 9, wherein a second planetary gear is engaged with a second output gear, Fig. 11 a view based on Fig. 9, wherein a first planetary gear is engaged with a first output gear.

[0033] In the Fig. 1a and Fig. Figure 1b shows a perspective view of an air outlet 10 according to a first embodiment. The air outlet comprises a housing 11 with an interior 29, to which an airflow 13 can be supplied via at least one air inlet 12. The housing 11 has at least one air outlet 14, through which the airflow 13 can be discharged from the interior 29 to a vehicle interior 15.

[0034] The air outlet 14 is provided with a first air deflection device 44, in this example comprising a plurality of first louvers 16, which are movably mounted and actuated. The first louvers 16 extend horizontally such that the airflow can be directed vertically by them. In other words, it can be controlled whether the airflow 13 – depending on the setting of the first air deflection device 44 – is directed upwards or downwards, or approximately horizontally with respect to a central axis a4 of the air outlet 14, with intermediate positions being possible.

[0035] Furthermore, the air outlet 10 has a second air deflection device 45 at the air outlet 14, comprising a plurality of second louvers 17. The second louvers 17 extend vertically in such a way that the airflow can be directed horizontally. In other words, the airflow 13 can be directed to the right, left, or centered relative to the central axis a4 by means of the second louvers 17, depending on their setting. Intermediate positions are also adjustable for the second louvers 17.

[0036] Alternatively or additionally, instead of the louver devices, other functional devices can also be driven by the drive device, which provide other functions of the air outlet.

[0037] The positioning of the air deflection of the first air deflection device 44 and the second air deflection device 45 is effected by means of a drive device 20, which is explained below. The drive device 20 has a drive 18 in the broadest sense, in the present embodiment a drive 18 in Fig. 1 electric motor (not shown). Other suitable drives can also be used. The drive 18 can generate a torque M1 and M2 directly or via an intermediate gearbox and thus drive a drive shaft 19 with an axis of rotation a1 in two opposite directions of rotation u1 and u2.

[0038] A drive gear 21, movable in directions x1 and x2 parallel to the axis of rotation a1 on the drive shaft 19, is rotationally fixed to the drive shaft 19. The drive gear 21 is positioned according to Fig. 1a engages with a first output gear 22, which is mounted on a first output shaft 31 with axis of rotation a2. A second output gear 24 with axis of rotation a3 is mounted on a second output shaft 32.

[0039] The axes of rotation a1, a2, and a3 are parallel to each other. The gears 21, 22, and 24 are helical, with the drive gear 21 being able to mesh with both the first output gear 22 and the second output gear 24. The helix angle of the gear teeth is, for example, 30° to 60°, preferably 40° to 50°, and particularly 45°. In the embodiment according to the Fig. 1 and Fig. In the first output gear 22 and the second output gear 24, the two are mounted separately on different axes of rotation a2 and a3. The output shafts 31 and 32 are parallel and spaced apart. Alternatively, the output gears 22 and 24 could also be mounted on a common output shaft.

[0040] By rotating the drive shaft 19 in the directions u1 or u2, the drive gear 21 can, due to forces acting on the helical gearing, move in the direction x1 or x2 along the drive shaft 19 and then engage with one of the output gears 22 or 24, each of the output gears 22 and 24 driving a functional device, which here is formed by an air deflector device. Fig. 1a the drive gear 21 is in an upper first position and is engaged with the first output gear 22 to drive the first air deflection device 44.

[0041] In Fig. 1b the drive gear 21 is arranged in a lower second position, e.g. for adjusting the second air deflector 45. It is in engagement with the second output gear 24 for controlling the second air deflector 45, e.g. for adjusting the second vertical louvers 17.

[0042] For better clarity, the drive device 20 is shown according to the Fig. 1a and Fig. 1b in the Fig. 2a and Fig. 2b is shown schematically, with the housing 11 of the air outlet 10 and the air deflectors 44 and 45 not shown. According to Fig. 2a the drive gear 21 is in a lower position in engagement with the second output gear 24. After Fig. 2b the drive gear 21 is engaged with the first output gear 22.

[0043] Since the first output gear 22 rotates only in the direction w and the second output gear 24 only in the direction o, the drive for the air deflectors 44 and 45 is designed as an endless loop. This means that, with regard to the functional devices of the present embodiment, in which these are designed as air deflectors 44 and 45, although the output gears 22 and 24 do not change their direction of rotation, e.g., by means of an intermediate gearbox, a crank, or a slide, the air deflectors 44 and 45 are driven in such a way that the vanes move alternately in a first and then a second direction. If the direction of the vanes is to be maintained, the drive must be stopped. For example, one air deflector is first adjusted, then the direction of rotation of the drive gear is reversed, and subsequently the other air deflector is adjusted.For example, if both air deflection devices are set as desired, the drive is stopped.

[0044] The output gear 24 has according to Fig. 2a In addition to the toothing 46 interacting with the drive gear 21, a toothing 36 of a second actuation 40 engages with the toothing 43 of a gear 37. The gear 37 includes a second eccentric pin 38, which is movable in a slot 39 of an oscillating actuation 41. When the output gear 24 rotates in the direction o, the gear 37 is moved in the direction Mv and the actuation 41 oscillates about the axis of rotation a5 of pin 42 in the directions q1 and q2.

[0045] It is in Fig. 2b It can be seen that a first eccentric pin 33 of a first actuating device 30 is rotatably connected to the first output shaft 31, which is received in an elongated hole 35 of an actuating element 34, e.g., a slide, wherein the actuating element 34 is mounted to be movable translationally in directions y1 and y2. When the first output gear 22 moves in direction w, the actuating element 34 is therefore moved alternately in directions y1 and y2.

[0046] The operating principle of the drive device 20 will be explained in more detail below using an example from the Fig. Figures 3 to 8 illustrate the second embodiment, in which, for the sake of clarity, only the drive gear 21 and the output gears 22 and 24 are shown, and in which, as an alternative to the first embodiment, the output gears 22 and 24 are rotatably mounted on a common axis of rotation a2. With respect to directions x1 and x2, the first output gear 22 and the second output gear 24 are fixedly mounted on the axis of rotation a2. The operation of the second embodiment corresponds in principle to that of the first embodiment.

[0047] The output gears 22 and 24 can, in principle, be mounted independently of each other on an axis that is fixed relative to a bearing structure and rotatable about the axis of rotation a2 relative to the bearing axis 23. Furthermore, each of the output gears 22 and 24 can be mounted separately and rotatably. It is irrelevant whether the respective output gear is mounted fixed to a rotatable shaft or, alternatively, rotatably on a stationary axis.

[0048] The first output gear 22 (see Fig. 3) The first output gear 24 is provided here for driving the first air deflection device 44 and the second output gear 24 for driving the second air deflection device 45. The first output gear 22 is arranged in a plane E1 and the second output gear 24 is arranged in a plane E2.

[0049] The output gears 22 and 24 are each formed with helical teeth 46 corresponding to the helical teeth 46 of the drive gear 21, the tooth flanks of which extend non-parallel to the axis of rotation a1. Due to a drive torque M1, a force Fr1 is generated at the gear teeth and a force Fa1 at the drive gear 21. The force Fa1 acts in the direction x2 and the force Fr1 in the tangential direction parallel to a plane formed by the drive gear 21, such that the drive gear 21 is rotated in the direction u1.

[0050] The output gears 22 and 24 have a locking device (not shown) relative to the bearing axis 23, which increases friction to such an extent that a frictional force opposes the movement about the axis of rotation a2 in the directions w1 and w2. The frictional force is so great that the respective output gear 22 or 24 does not rotate as long as the drive gear 21 can move axially in the direction x2.

[0051] Due to the free movement of the drive gear 21 in direction x2, the force Fa1 causes a movement of the drive gear 21 from the in Fig. In the position shown in Figure 3, in which it is arranged with a first stop surface 27 against a first stop 25, the drive gear 21 screws itself in the direction of x2 towards a second stop 26. In other words, the drive gear 21 screws itself in the direction of x2 by engaging with the first output gear 22 and successively by engaging with the second output gear 24. According to Fig. In position 4, the drive gear 21 is in an intermediate position. During the movement between the first stop 25 and the second stop 26, the drive gear 21 is therefore temporarily engaged with both output gears 22 and 24.

[0052] When a second stop surface 28 of the drive gear 21 is in contact with the second stop 26 (see Fig. 5), the drive gear 21 is engaged with the second output gear 24 and disengaged from the first output gear 22.

[0053] When the second stop surface 28 of the drive gear 21, after its movement in direction x2, is in contact with the second stop 26, the force Fa1 is absorbed by the latter, and the force Fr1 drives the second output gear 24. The drive gear rotates in direction u1, and the output gear 24 rotates in direction w1. The output gear 24 is driven until the direction of the drive shaft 19 reverses or the drive shaft 19 comes to a standstill by switching off the motor 18.

[0054] The drive shaft 19 is driven by a torque M2 in the direction of rotation u2 (see Fig. 6) A force Fa2 is generated in the direction of x1, as well as a tangential force Fr2, which acts on the drive gear 21, causing it to rotate in the direction of u2. As a result, the drive gear 21 moves along the axis of rotation a1 in the direction of x1. According to Fig. 7 the drive gear 21 is in an intermediate position in engagement with both output gears 22 and 24.

[0055] The drive gear 21 continues its movement in direction x1 until the stop surface 27 is in contact with the stop 25. When the stop surface 27 of the drive gear 21 is in contact with the stop 25, the stop 25 absorbs the force Fa2, while the force Fr2 drives the output gear 22 in the direction of rotation w2 until the motor 18 is switched off or the direction of rotation of the drive shaft 19 is reversed.

[0056] The direction reversal can be performed by a control unit (not shown) or manually.

[0057] As an alternative to the depicted design of the air outlet 10, at least one additional output gear could be provided, for example, within the plane E1 formed by the first output gear 22 and / or within the plane E2 formed by the second output gear 24, for driving at least one additional functional device. This additional output gear would engage with the drive gear 21 when the latter is engaged with the first output gear 22 or when the latter is engaged with the second output gear 24. Further functional devices of the air outlet 10 could be driven by the additional output gear(s).

[0058] According to a further embodiment, which can be implemented in addition to or as a replacement for the previously described embodiments, there could be not only two planes E1 and E2 with output gears 22 and 24, but at least one further output gear arranged between these output gears 22 and 24 in at least a third plane, with each further output gear being engaged with at least one further functional device. In this embodiment, additional stops, e.g., at least two stops, must be controllably displaceable into the path of motion of the drive gear 21 in order to stop the axial movement in directions x1 and x2 in the plane of the further output gear and then drive this additional output gear.

[0059] A third embodiment is described in the Fig. Figures 9 to 11 illustrate this embodiment. In this embodiment, the gears can be helical or spur gears, as in the first embodiments. Furthermore, the use of friction wheels is also possible.

[0060] The drive gear 21' is fixedly mounted here, preventing rotation and parallel to the drive shaft 19' with respect to directions x1 and x2. Torque is transmitted indirectly to the output gears 22 and 24 via a first planet gear 47 and a second planet gear 48. The first planet gear 47 and the second planet gear 48 are in constant mesh with the drive gear 21'. Both planet gears 47 and 48 are mounted on a common carrier 49, which is rotatable about the axis of rotation a1 of the drive shaft 19'. The carrier 49 includes arms 50a and 50b, which form an angle α with each other, such that the planet gears 47 and 48 are spaced apart from each other on the circumference of the drive gear 21'.

[0061] The distance between the outer circumference of the drive gear 21' and the outer circumference of the first output gear 22, as well as between the outer circumference of the drive gear 21' and the outer circumference of the second output gear 24, is smaller than the diameter of the planet gears 47 and 48, which may have the same or different diameters. The size of the planet gears 47 and 48, the drive gear 21, and the output gears 22 and 24 are selected such that, when the carrier 49 rotates, the planet gears 47 and 48 can engage with the output gears 22 and 24 while simultaneously engaging with the drive gear 21.

[0062] The angle α is designed such that in a neutral position none of the planet gears is in engagement with either of the output gears 22 and 24, in a first pivoting position of the carrier 49 the planet gear 48 is in engagement with the output gear 24 and in a second pivoting position the planet gear 47 is in engagement with the output gear 22.

[0063] In the Fig. 9 and Fig. Figure 10 merely shows schematically that the output gear 22 is in engagement with a gear of the first air deflection device 44 and the output gear 24 is in engagement with a gear of the second air deflection device 45 as a functional device.

[0064] If a moment M1 is applied to the drive gear 21' (see Fig.10), the carrier 49 is rotated in the direction u1 about the axis of rotation a1 and the planet gear 48 is moved into engagement with the output gear 24. Due to the transmission of the torque M1 to the planet gears 47 and 48, a moment in the direction u1 is generated in the carrier 49 due to a resistance in the planet gears 47 and 48, which rotates the carrier until the planet gear 48 is in engagement with the output gear 24 and drives it.

[0065] When a torque M2 in the opposite direction of rotation u2 is applied to the drive gear 21, the carrier 49 pivots in the direction of u2 and the planet gear 47 engages with the output gear 22 and drives it.

[0066] In this embodiment, friction wheels could also be used instead of gears.

[0067] The output gears 22 and 24 interact, for example, as in the preceding embodiments, with the functional devices which can, for example, control lamellae.
