Abstract
Description
The invention relates to an air vent for a vehicle.Such an air vent is described in DE 10 2020 133 649 A1. It comprises a chamber to which an air flow is supplied via an air inlet, wherein the air flow is discharged to the vehicle interior via at least one air outlet. Two movable ventilation grilles with vertically or horizontally arranged louvers are assigned to the air outlet. Each ventilation grille has a drive with an electric motor and a mechanical gear for pivoting the plates.The transmission comprises a first drive with a first drive gearwheel which is arranged fixedly on the motor shaft of an electric motor, and two driven gearwheels which are rotationally connected to one another and can be moved axially and which are at an axial distance from one another. The distance corresponds to the width of a rack with which the output gears are movable into mesh. The rack moves the vanes in one direction. All the gears are helical.Upon movement of the drive gear in a first direction, the driven gears are axially displaced against the force of a first spring, so that a first gear is in engagement with the drive gear and in engagement with the toothed rack. The rack is driven in a first direction. An opposite movement of the drive gear results in the driven gears being displaced axially in the opposite axial direction against the force of a second spring, so that the drive gear and the toothed rack are in engagement with a second driven gear. The rack is driven in a second direction.The second ventilation grille is moved by a similarly designed drive.According to a first aspect, it was an object of the invention to design an air vent with a drive which makes it possible to save on the outlay on parts and the installation space.The object was achieved by an air vent having the features of claim 1.The air vent according to the invention is intended for a vehicle. In the sense of the application, a vehicle is a land, air or water vehicle. The air vent comprises an air inlet, and an air outlet, and at least one movable first functional device and one movable second functional device. The first functional device can be provided, for example, by a first air deflecting device, comprising at least one lamella, the longitudinal central axis of which is oriented approximately horizontally. The second functional device is e.g. a second air deflecting device, comprising at least one lamella, the longitudinal central axis of which is oriented approximately vertically.Functional device is, for example, a device which provides specific functions of the air vent and has at least one movable part which is movable by a drive device of the air vent.The air vent comprises a drive device for driving the first functional device and the second functional device. The drive device is provided with a drive shaft which is rotatable in opposite rotational directions about a geometric drive axis, by means of which a helical drive gear can be driven in opposite rotational directions.The air vent further comprises a first driven gearwheel helical to a geometric first driven rotational axis and a second driven gearwheel helical to a geometric second driven rotational axis for driving the first functional device and the second functional device of the air vent. The drive gear is connected to the drive shaft in a rotationally fixed manner 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. The stops are, for example, end stops of the movement. The drive rotational axis and the driven rotational axes are, for example, parallel to each other.The inhibition of the respective output gears should be such that the output gears are prevented from rotating before the input gear moves into contact with the first stopper or the second stopper and thus reaches its end position. The inhibition takes place, for example, by a downstream mechanism or, for example, by inhibiting means in the form of springs and / or dampers.The air vent according to the invention comprises a drive device, with which at least one first functional device and one second functional device can be driven. It is also possible to drive more than two functional devices, for example three or four functional devices. The output rotation axes can be spaced apart from one another according to the invention, which enables a flexible construction. The air vent requires little installation space and the number of parts is reduced in comparison with air vents from the prior art.The output gears are, for example, fixedly arranged in the direction parallel to the output rotational axis. Each of the first and second driven gears is drivable by the axial positioning of the drive gear. The direction of rotation of the drive gear determines whether the drive gear is positioned on the first driven gear or on the second driven gear. At least two stops position the drive gear to be in mesh with the first output gear or the second output gear.When the drive gear is in engagement with the first driven gear or with the second driven gear, it can additionally be in engagement with at least one further gear and drive it. In this way, a further functional device can be moved. The further gearwheel can be arranged, for example, in a plane formed by the respective output gearwheel or can be arranged in a plane which is formed at an angle to the plane formed by the respective output gearwheel.The movement of the output gears relative to the output rotational axis is inhibited, for example, by friction means. By restraining the output gears, a counterforce to the circumferential force of the drive gear is generated, at which the drive gear can be supported for axial movement. In other words, the drive gearwheel can be screwed along the driven gearwheels and thereby move along the drive axis of rotation when the driven gearwheels are stationary due to a counterforce. If the counter force is large enough, the drive gear quickly moves to the opposing stopper upon reversal of the direction of the drive rotation axis.For example, at least one first functional device is designed as an air deflector with at least one movable slat which can be driven by the first output gearwheel. The air deflecting device comprises e.g. at least one lamella, in particular a plurality of lamellae. The slat forms an air guiding element in order to give the air flow a direction. For example, at least one second functional device is designed as an air deflector with at least one movable slat which can be driven by the second output gearwheel.The first blades are arranged, for example, approximately horizontally and are suitable for guiding the air flow upward in a first end position, downward in a second end position and straight ahead in a central position. Further intermediate positions can be present and can be selected as desired.The second air deflecting device comprises e.g. at least one lamella, in particular a plurality of lamellae. The second blades are arranged approximately vertically, for example, and are suitable for guiding the air flow in a first end position to the right, in a second end position to the left and in a central position straight ahead. Further intermediate positions can be present and can be selected as desired.The movement of the first air deflector and / or of the second air deflector is, for example, such that the slats of a respective air deflector are synchronously rotated by means of a synchronization device. For example, each slat has a lever arm and each lever arm is pivotally connected to a driver bar. The driver strips are designed, for example, as toothed racks, which are each in engagement with a driven gearwheel.The air vent has, for example, a control device, with which the drive device can be controlled in such a way that the first air deflecting device and the second air deflecting device are set in the desired position. As soon as the respective air deflecting device is in the desired position, for example, the drive gearwheel is reversed in direction. The respective other air deflecting device can then be set in the desired position.A sensor device at the end stops could serve, for example, as a detector, which transmits the disk position to the control device as a function of the direction of rotation of the drive wheel.The air vent has, for example, a control device with which, additionally or as an alternative embodiment, the direction of rotation of the drive shaft can be controlled manually in an operating mode. In this case, the drive gear moves in the direction parallel to the axis of rotation against a stop depending on the direction of rotation and then drives the driven gear with which it is engaged according to its position.According to a second aspect, the invention relates to a vehicle interior having at least one air vent.The same state of the art is relevant here as in the first aspect of the invention.It was an object of the invention to provide a vehicle interior with an air vent with a drive, which permits a saving in the outlay on parts and in the installation space.The object was achieved by a vehicle interior comprising at least one air vent according to the first aspect of the invention. A plurality of the aforementioned air outflow devices can be formed, for example, in the dashboard, in the interior trim panels or in the central console.Exemplary embodiments of the invention are described by way of example in the following description of the figures, also with reference to the drawings.

The air vent comprises a housing 11 with a housing interior 29 to which an air flow 13 can be supplied via at least one air inlet 12. The housing 11 has at least one air outlet 14, via which the air flow 13 can be emitted from the housing interior 29 to a vehicle interior 15.The air outlet 14 is provided with a first air deflecting device 44, in the present example comprising a plurality of first slats 16, which are movably mounted and drivable. The first louvers 16 extend horizontally such that the first louvers can direct the flow of air vertically. In other words, it is possible to regulate whether the air flow 13 is directed upward or downward or approximately horizontally with respect to a central axis a 4 of the air outlet 14, depending on the setting of the first air deflection device 16.Furthermore, the air outlet 10 has a second air deflecting device 45 at the air outlet 14, here comprising a plurality of second slats 17. The second louvers 17 extend vertically such that the air flow can be horizontally directed with the second louvers 17. In other words, the air flow 13 can be directed by means of the second fins 17, depending on their setting, to the right or left or centrally with respect to the central axis a 4. Intermediate positions can also be set in the case of the second plates 17.Alternatively or additionally, instead of the slat devices, other functional devices can also be driven by the drive device, which provide other functions of the air vent.The positioning of the air deflection of the first air deflection device 44 and of 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 exemplary embodiment an electric motor not shown in FIG. 1. Other suitable drives may also be used. The drive 18 can generate a torque M 1 and M 2 directly or by means of an interposed transmission and thus drive a drive shaft 19 with a rotational axis a 1 in two opposite rotational directions u 1 and u 2.A drive gear 21 movable in directions x1 and x2 parallel to the axis of rotation a1 on the drive shaft 19 is connected to the drive shaft 19 in a rotationally fixed manner. According to FIG. 1 a, the drive gearwheel 21 is in mesh with a first driven gearwheel 22, which is mounted on a first output shaft 31 with the axis of rotation a 2. A second output gearwheel 24 with the axis of rotation a 3 is mounted on a second output shaft 32.The axes of rotation a 1, a 2 and a 3 are parallel to one another. The gears 21, 22 and 24 are helical, wherein the drive gear 21 can be meshed with both the first driven gear 22 and the second driven gear 24. The angle of inclination of the toothing is e.g. 30° to 60°, preferably 40° to 50°, in particular 45°. In the embodiment according to FIGS. 1 and 2, the first output gearwheel 22 and the second output gearwheel 24 are mounted separately on different axes of rotation a 2 and a 3. The output shafts 31 and 32 are formed in parallel and spaced apart from each other. Alternatively, the output gears 22 and 24 could also be mounted on a common output shaft.By rotating the drive shaft 19 in the directions u1 or u2, the drive gearwheel 21 can slide in the direction x1 or x2 along the drive shaft 19 due to forces acting on the helical gearing and then move into engagement with one of the driven gearwheels 22 or 24, wherein each of the driven gearwheels 22 and 24 drives a functional device which is here formed by an air deflector in each case. As shown in FIG. 1 a, the drive gear 21 is in an upper first position and is in mesh with the first driven gear 22 for driving the first air deflector 44.In FIG. 1 b, the drive gearwheel 21 is arranged in a lower second position, for example for the displacement of the second air deflector 45, and it is in engagement with the second driven gearwheel 24 for controlling the second air deflector 45, for example for the displacement of the second vertical slats 17.For better clarity, the drive device 20 according to FIGS. 1 aand 1 bis schematically illustrated in FIGS. 2 aand 2 b, wherein the housing 11 of the air vent 10 and the air deflecting devices 44 and 45 are not shown. According to FIG. 2 a, the drive gearwheel 21 is in a lower position in engagement with the second driven gearwheel 24.Since the first driven gear 22 rotates only in the direction of rotation w and the second driven gear 24 rotates only in the direction of rotation o, the drive of the air deflectors 44 and 45 is configured as an endless loop. That is, with respect to the functional devices of the present embodiment, in which they are formed as air deflectors 44 and 45, although the driven gears 22 and 24 do not change their rotational direction, for example, by means of an intermediate gear or crank arm or slider, the air deflectors 44 and 45 are driven such that the vanes move alternately in a first and then in a second direction. If the direction of the plates is to be maintained, the drive must be stopped. For example, first an adjustment of one air deflector takes place, then a reversal of the direction of rotation of the drive gear and subsequently an adjustment of the other air deflector takes place. For example, if both air deflectors are set as desired, the drive is stopped.According to FIG. 2 a, in addition to the toothing 46 interacting with the drive gearwheel 21, the driven gearwheel 24 has a toothing 36 of a second actuation 40, which is in engagement with the toothing 43 of a gearwheel 37. The gearwheel 37 comprises a second eccentric pin 38 which is movable in an elongated hole 39 of a pivotably movable actuation 41. As the driven gear 24 rotates in the direction o, the gear 37 is moved in the direction Mv, and the actuator 41 swings about the rotational axis a5 of pin 42 in the directions q1 and q2.It can be seen in FIG. 2 b that a first eccentric pin 33 of a first actuation 30 is rotatably connected to the first output shaft 31, said eccentric pin being accommodated in an elongated hole 35 of an actuation piece 34, for example of a slide, wherein the actuation piece 34 is mounted such that it can move translationally in directions y 1 and y 2. When the first output gear 22 is moved in the direction w, therefore, the actuating piece 34 is moved alternately in the directions y1 and y2.The mode of operation of the drive device 20 is explained in more detail below with reference to a second exemplary embodiment shown in FIGS. 3 to 8, in which, for the sake of clarity, only the drive gearwheel 21 and the driven gearwheels 22 and 24 are shown, and wherein the driven gearwheels 22 and 24 are rotatably mounted on a common axis of rotation a 2 as an alternative to the first exemplary embodiment. With respect to the directions x 1 and x 2, the first driven gearwheel 22 and the second driven gearwheel 24 are fixedly mounted on the axis of rotation a 2. The mode of operation of the second exemplary embodiment corresponds in principle to that of the first exemplary embodiment.The output gears 22 and 24 can in principle be mounted on an axis that is rotationally fixed relative to a bearing structure so as to be rotatable independently of one another relative to the bearing axis 23 about the axis of rotation a 2. Moreover, each of the driven gears 22 and 24 may be separately rotatably supported. It is immaterial whether the respective output gearwheel is mounted on a rotatable shaft in a rotationally fixed manner or alternatively is also mounted rotatably on an immovable axis.The first output gearwheel 22 (see FIG. 3 ) is provided here for driving the first air deflector 44 and the second output gearwheel 24 is provided for driving the second air deflector 45. The first output gear 22 is arranged in a plane E 1 and the second output gear 24 is arranged in a plane E 2.The driven gearwheels 22 and 24 are likewise each formed, corresponding to a helical toothing 46 of the drive gearwheel 21, with a helical toothing 46 whose tooth flanks extend nonparallel relative to the axis of rotation a 1. Due to a drive torque M 1, a force Fr 1 and a force Fa 1 are produced on the drive gear 21 at the toothing, and the force Fa 1 acts in the direction x 2 and the force Fr 1 acts in the tangential direction parallel to a plane formed by the drive gear 22, such that the drive gear 21 is rotated in the direction u 1.The output gears 22 and 24 have, relative to the bearing axis 23, an inhibiting means, not shown, which increases the friction in such a way that a frictional force counteracts the movement about the axis of rotation a 2 in the directions w 1 and w 2. The frictional force is so large that the respective driven gear 22 or 24 does not rotate as long as the drive gear 21 can move axially in the direction x2.Due to the free movability of the drive gearwheel 21 in the direction x 2, the force Fa 1 causes a movement of the drive gearwheel 21 from the position shown in FIG. 3, in which it is arranged with a first stop surface 27 on a first stop 25, in the direction x 2 toward a second stop 26. As shown in FIG. 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 gearwheel 21 is thus temporarily in engagement with both driven gearwheels 22 and 24.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 in mesh with the second driven gear 24 and disengaged from the first driven gear 22.If the second stop surface 28 of the drive gearwheel 21 is in contact with the second stop 26 after its movement in the direction x 2, the force Fa 1 is absorbed by the latter and the force Fr 1 drives the second driven gearwheel 24. In this case, the drive gearwheel rotates in the direction u 1 and the driven gearwheel 24 rotates in the direction w 1. The driven gear 24 is driven until a reversal of the direction of the drive shaft 19 takes place or the drive shaft 19 rests by switching off the motor 18.If the drive shaft 19 is driven by a torque M 2 in the direction of rotation u 2 (see FIG. 6 ), a force Fa 2 in the direction x 1 and a tangential force Fr 2 are produced which acts on the drive gearwheel 21, so that the latter rotates in the direction u 2. As a result, the drive gear 21 moves along the rotation axis a 1 in the direction x 1. As shown in FIG. 7, the drive gear 21 is in an intermediate position in mesh with both driven gears 22 and 24.The drive gear 21 continues its movement in the 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 receives the force Fa 2, while the force Fr 2 drives the driven gear 22 in the rotational direction w 2 until the motor 18 is switched off or a reversal of the direction of rotation of the drive shaft 19 is carried out.The reversal of direction can be carried out by a control, not shown, or manually.As an alternative to the illustrated embodiment of the air vent 10, at least one additional driven gear for driving at least one additional functional device could be formed e.g. within the plane E 1 formed by the first driven gear 22 and / or e.g. within the plane E 2 formed by the second driven gear 24, which additional driven gear is in engagement with the drive gear 21 when it is in engagement with the first driven gear 22 or when it is in engagement with the second driven gear 24. With the additional driven gearwheel or the additional driven gearwheels, further functional devices of the air vent 10 could be driven.According to a further embodiment, which can be realized in addition or in replacement of the previously illustrated embodiments, not only could two planes E 1 and E 2 with output gears 22 and 24 be present, but at least one further output gear, which is arranged between these output gears 22 and 24 in at least one third plane, wherein each further output gear is in engagement with at least one further functional device in each case. In this embodiment, additional stops, e.g. at least two stops, must be displaceable in the path of movement of the drive gear 21 under the control of a controller in order to stop the axial movement in the directions x1 and x2 in the plane of the further driven gear and then drive this additional driven gear.A third embodiment is shown in FIGS. 9 to 11. In this embodiment, the gears can be helical or even straight as in the first embodiments. Furthermore, the use of friction wheels is also possible.The drive gearwheel 21' is fixedly mounted here in a rotationally fixed manner and parallel to the drive shaft 19' with respect to directions x1 and x2. A torque is transmitted to the driven gears 22 and 24 indirectly via a first planetary gear 47 and a second planetary gear 48, and the first planetary gear 47 and the second planetary gear 48 are constantly in engagement with the drive gear 21'. Both planetary 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 comprises 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 at the circumference of the drive gear 21'.The distance between the outer circumference of the drive gearwheel 21' and the outer circumference of the first driven gearwheel 22 and between the outer circumference of the drive gearwheel 21' and the outer circumference of the second driven gearwheel 24 is smaller than the diameter of the planetary gears 47 and 48, which can have the same or different diameters. The sizes of the planet gears 47 and 48, the drive gear 21, and the driven gears 22 and 24 are selected such that upon rotation of the carrier 49, the planet gears 47 and 48 can move into engagement with the driven gears 22 and 24 while engaging the drive gear 21.The angle α is formed such that in a central position none of the planetary gears is in engagement with one of the output gears 22 and 24, in a first pivot position of the carrier 49, the planetary gear 48 is in engagement with the output gear 24, and in a second pivot position, the planetary gear 47 is in engagement with the output gear 22.In FIGS. 9 and 10, it is only schematically shown that the driven gearwheel 22 is in engagement with a gearwheel of the first air deflector 44 and the driven gearwheel 24 is in engagement with a gearwheel of the second air deflector 45 as a functional device.When a torque M1is applied to the drive gear 21' (see FIG. 10 ), the carrier 49 is rotated in the direction u1about the axis of rotation a1and the planetary gear 48 is moved into engagement with the driven gear 24. Due to the transmission of the torque M 1 to the planetary gears 47 and 48, a torque in the direction u 1 arises due to a inhibition in the planetary gears 47 and 48 in the carrier 49, which torque rotates the carrier until the planetary gear 48 is in engagement with the output gear 24 and drives it.At a torque M2in the opposite direction of rotation u2on the drive gearwheel 21, the carrier 49 pivots in the direction u2and the planetary gearwheel 47 engages with the driven gearwheel 22 and drives it.Instead of the gears, friction wheels could also be used in this embodiment.The output gears 22 and 24 cooperate, for example, as in the preceding exemplary embodiments, with the functional devices which can control, for example, plates.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
