Description

Ventilation device

Technical Field

The invention relates to a ventilation device for controlling an air flow in an interior of a motor vehicle.

Background

Ventilation devices for the interior of a motor vehicle, such as conventional ventilation devices with intersecting horizontal and vertical lamellae (H and V lamellae), have already been disclosed and are widely used. Furthermore, motor-adjustable ventilation devices are known, in which the user does not have to adjust the lamellae directly (for example by means of a cursor arranged at the lamellae). A disadvantage of the known ventilation devices is generally the limited possibility of adjusting their size and the deflection angle.

Disclosure of Invention

The object of the present invention is to provide an electrically adjustable ventilation device for controlling an air flow, which is very compact and offers the greatest possible degree of adjustment of the air flow to be controlled. According to the invention, this object is achieved by the features of claim 1. Advantageous embodiments are described in the dependent claims.

The ventilation device according to the invention comprises in particular only a single ventilation flap, by means of which the air flow flowing into the interior of the vehicle can be deflected. The ventilation device can be designed very compact since only a single ventilation flap is used. However, a plurality of, in particular rigidly connected or coupled, ventilation flaps are also possible. Furthermore, the ventilation device comprises a first and a second adjusting element for adjusting the ventilation flap and, in particular, only a single electric drive, by means of which the first or the second adjusting element can be driven. The first and second adjusting elements can be moved relative to one another in at least one first and second direction by relative movement with respect to one another or together in the first and second direction. In particular, "relative movement" is to be understood as a rotational movement of the first and second adjusting element about a common rotational axis. In other words, both the first and the second adjustment element can be rotated clockwise or counterclockwise about the rotation axis. A clockwise or counterclockwise joint rotation of the first and second adjusting element is also possible. Upon joint rotation about the axis of rotation, the adjusting elements move relative to one another.

The first adjusting element has at least one pivot bearing element in which the ventilation flap is mounted so as to be pivotable about a pivot axis. In particular, the pivot bearing element is configured as a bushing or slide bearing in the first adjusting element, in which the pin connected to the ventilation flap can be pivoted in a mating manner (passagsatrigi) about the pivot axis. The pivot axis and the rotation axis are in particular oriented orthogonally to one another, but in no case parallel to one another. In particular, the first adjusting element has two, in particular identical, pivot bearing elements, which ensures that the ventilation flap is reliably supported in the first adjusting element. The pivot bearing elements are arranged on the pivot axis, into which pegs connected to the ventilation flap engage in each case. In particular, the ventilation flap is mounted in the first adjusting element in an axially non-displaceable manner by means of a pivot bearing element.

The second actuating element has a kinematic transmission element which is arranged on the second actuating element and is operatively connected to the ventilation flap. The at least one pivot bearing element of the first adjusting element forms a lever for the ventilation flap together with the kinematic transmission element. The kinematic transmission element, in conjunction with the pivot bearing element, ensures that a pivoting movement of the ventilation flap about the pivot axis is brought about by a relative movement of the first actuating element and the second actuating element, i.e. in particular when the first and second actuating elements are rotated relative to one another about the axis of rotation in the first or second direction. The kinematic transmission element can be configured, for example, as a transmission having a first and a second transmission element. The first transmission element is rigidly connected to the first adjusting element, in particular by means of a strut, and is arranged coaxially to the axis of rotation. The second transmission element is in particular rigidly connected to the ventilation flap and is oriented coaxially to the pivot axis. The first and second transmission elements are in engagement, whereby a relative movement of the first and second adjusting elements relative to each other can be transmitted to the ventilation flap.

By a movement of the first actuating element relative to the second actuating element about the axis of rotation in a first direction (for example clockwise), the ventilation flap is pivoted in a first pivoting direction up to a first maximum position. By a movement of the first adjusting element relative to the second adjusting element in a second direction (i.e. correspondingly counterclockwise), the ventilation flap is pivoted in a second pivoting direction until the ventilation flap reaches a second maximum position, wherein the second pivoting direction is opposite to the first pivoting direction. In order to pivot the ventilation valve into the first and second maximum positions, the first adjusting element can be stationary and the second adjusting element can be moved, in particular rotated, relative to the first adjusting element in the first and second direction (i.e. in particular clockwise or counterclockwise). For the sake of completeness, it should be mentioned that the second adjusting element can also be stationary and the first adjusting element correspondingly moves relative to this second adjusting element.

The stops delimit the first and second maximum position of the ventilation flap in the first and second pivoting directions. This stop is essential for the invention, so that the first and second adjusting elements can be rotated together about the axis of rotation in the first or second direction.

In the first and second maximum position, the first adjusting element, the second adjusting element and the ventilation flap cannot be moved relative to one another in the first or second direction, but can be moved together in the first or second direction. For example, if the second adjusting element is moved, in particular rotated, in relation to the first adjusting element in a first direction, wherein the first adjusting element is in this case initially not movable, the ventilation flap pivots into a first maximum position, wherein the stop stops. Then, when the first direction is further moved, the first and second adjusting elements move together with the ventilation flap in the first direction, in particular both adjusting elements and the ventilation flap rotate together in the first direction about the axis of rotation. In a diagrammatic manner, the second actuating element "drives" the first actuating element and the ventilation flap as soon as the first maximum position is reached.

If, since the first maximum position or stop is reached, the second adjusting element is moved relative to the first adjusting element in the second direction, in particular is rotated about the axis of rotation, the ventilation flap is pivoted out of the first maximum position in the direction of the second maximum position until the second maximum position is reached, which is in turn delimited by the stop. Then, when the first and second adjusting elements are moved further in the second direction, the first and second adjusting elements move together with the ventilation flap in the second direction, in particular both adjusting elements and the ventilation flap rotate together in the second direction about the axis of rotation. In a geometric sense, the second actuating element "drives" the first actuating element as soon as the second maximum position is reached. Of course, the first adjusting element can also be moved relative to the second adjusting element in the first or second direction in order to achieve the same result. In particular, the adjusting element and thus the ventilation flap can be rotated by up to 360 ° about the axis of rotation when the ventilation flap is in the first or second maximum position.

In a further advantageous embodiment of the invention, the first adjusting element is in the form of a first ring and the second adjusting element is in the form of a second ring, wherein the first and second rings are rotatable about the axis of rotation in a first and a second direction and are arranged in particular in a vertically overlapping manner. By means of this embodiment and in particular by means of the arrangement, a very compact design of the ventilation device is ensured.

In a further advantageous embodiment of the invention, the stop is formed at the second adjusting element, between the first and second adjusting elements or in the kinematic transmission element. This stop can be realized, for example, by: the ventilation flap is in direct contact with a first end face of a second adjusting element, which is in particular in the form of a ring. It is also possible to arrange a stop element, in particular in the form of a peg, on the first adjusting element and a groove on the second adjusting element. The opposite arrangement is also possible. The groove extends in particular in the second end face of the second ring. The peg is arranged in particular at the first end face of the first ring and engages into the groove. The width of the slot in combination with the width of the peg defines the movability of the peg in the slot and thus the maximum movability of the first ring relative to the second ring. The list of possible embodiments of the stop is not exhaustive.

In a further advantageous embodiment of the invention, the kinematic transmission element has a pivot compensation element, in particular a slot. Preferably, the ventilation flap has a peg which engages into a pivot-balancing element of the kinematic transmission element. The relative movement of the first and second adjusting element is transmitted to the ventilation flap via the peg, whereby this ventilation flap is pivoted about the pivot axis. The pin can slide in the pivot-balancing element parallel to the axis of rotation, while the ventilation flap is pivoted between the maximum positions, thereby preventing the ventilation flap from being tilted in the first adjusting element. In other words, the peg can be displaced in the axial direction in relation to the axis of rotation in the pivoting balancing element. The slot into which the peg engages can also be introduced directly into the second ring.

In order to ensure the most convenient and simple pivotability of the ventilation flap, in a further advantageous embodiment of the invention, the kinematic transmission element is arranged at the second adjusting element in a manner rotatable about a transmission element longitudinal axis, which is oriented in particular parallel to the axis of rotation. If the transmission element does not have such a rotatability, the ventilation flap can be skewed in the second adjusting element.

As already explained, the ventilation device has an electric drive, with which the first or the second adjusting element can be driven. In a further advantageous embodiment of the invention, the electric drive has a gear wheel which meshes with a corresponding roller edge, which is arranged on the first or second adjusting element. In this way, the first or the second adjusting element can be driven in a simple manner by the electric drive.

In a further advantageous embodiment of the invention, the ventilation device has a detent element which interacts with the first or second adjusting element in such a way that, when the ventilation flap is moved from the first maximum position into the second maximum position, the common movement of the first and second adjusting element in the first or second direction is blocked. In particular, the braking element is configured as a friction brake, which in particular continuously brakes the first or second adjusting element. In particular, the braking element interacts with an adjusting element, which is not driven by an electric drive. The braking element ensures that the non-driven adjusting element is stationary when pivoting the ventilation flap. If the first or second maximum position is reached, the actuated actuating element "entrains" the actuated actuating element, whereby the braking effect is overcome and the actuating element which has not been moved so far is actuated by the actuated actuating element against the force of the braking element. In particular, in this case, the braking force of the braking element must be matched to the strength of the electric drive.

The features and feature combinations mentioned above in the description, embodiments and embodiments of the invention and the features and feature combinations mentioned below in the description of the figures and/or depicted in the figures can be used not only in the respectively stated or depicted combination but also in any other combination in principle or alone. Embodiments of the invention may not have all the features of a dependent claim. The individual features of a claim can also be replaced by other disclosed features or combinations of features.

It shows that:

fig. 1 is a perspective schematic view of a ventilation device according to the present invention;

fig. 2 shows the ventilation device of fig. 1 in the maximum position.

Detailed Description

Fig. 1 shows a ventilation device 1 according to the invention. The ventilation device 1 comprises a first adjusting element 2, which is configured as a first ring 3, wherein the first ring 3 has a first end face 4, which is circular, and a second end face 5, which is circular. In addition, the ventilation device 1 comprises a second adjusting element 6, which is configured as a second ring 7, wherein the second ring 7 has first and second end faces 8, 9, which are circular. The first ring 3 and the second ring 7 are arranged coaxially with respect to the rotation axis D. The first and second rings 3, 7 are slidable relative to each other at their respective second end faces 5, 9. The first ring 3 and the second ring 7 are each able to rotate in a first direction of rotation D about an axis of rotation D₁Up and in a first direction of rotation D₁Opposite second direction of rotation D₂And (4) upward rotation. Thus, the first and second rings 3, 7 can be in a first or second rotational direction D relative to each other₁、D₂Are rotated relative to each other. Furthermore, the first and second rings 3, 7 can be common in the first or second direction of rotation D₁、D₂And (4) upward rotation.

At the electric drive 11 of the ventilation device 1, a gear wheel 12 is arranged, which engages into the border 10 of the second ring 7. The second ring 7 can be driven in a first or second direction of rotation D by an electric drive 11₁、D₂And (4) upward rotation.

The ventilation device 1 comprises a ventilation flap 13 which engages into a pivot bearing element 16 by means of a pin 14 and is in the neutral position in fig. 1. The ventilation flap 13 is mounted in the first ring 3 by means of a pin 14 and can be pivoted in a first and a second pivoting direction S by means of a pivot axis S₁、S₂An upper pivot, said pivot axis being oriented orthogonally to the rotation axis D. The first ring 3 comprises two pivot bearing elements 16 in the first ring 3, which pivot bearing elements are arranged on the pivot axis S. Correspondingly, the ventilation flap 16 comprises two pins 14 (wherein, due to the perspective illustration, only one pin 14 is shown). Furthermore, a pin 15 is arranged at the ventilation flap 13, which engages into the kinematic transmission element 17. The kinematic transmission element 17 has a pivot-compensating element 18, which is configured as an elongated hole 19, which extends along the transmission element axis a. The transfer element axis a extends parallel to the rotation axis D.

If the second ring 7 is in the first rotational direction D with respect to the first ring 3₁An upward movement, wherein in this case the first ring 3 is positively braked by the spring-loaded brake element 22, whereby this first ring cannot rotate together with the second ring 7, the ventilation flap 16 is moved in the direction S₂Up to the first maximum bit state (shown in figure 2). In this case, the peg 15 slides parallel to the transmission element axis a, so that the ventilation flap 13 does not skew when pivoting. Furthermore, the kinematic transmission element 17 can be rotated about the transmission element axis a, whereby the risk of the ventilation flap 13 being skewed is further reduced. If the first maximum position is reached, as shown in fig. 2, the stop prevents the ventilation flap 13 from moving further beyond the first maximum position. Is carried out in the following mannerNow, the stopping part: the stop element 21 arranged at the second end face 5 of the first ring 3 is slidable in a groove 20 arranged in the second end face 9 of the second ring 7. The pivotability of the ventilation flap 13 about the pivot axis S is therefore limited to the maximum movability of the stop element 21 in the groove 20. The stop element 21 is located at the end of the groove 20 if the second ring 7 reaches the first maximum position. If now further in the first rotational direction D₁The second ring 7 is rotated upward, the braking force of the braking element 22 is overcome, so that the first ring 3 together with the second ring 7 and thus the ventilation flap 13 is rotated in the first direction of rotation D₁Upper about the rotation axis D. If then in the second direction of rotation D₂By rotating the second ring 7 upwards, the ventilation flap 13 is in the direction S₁The upper pivot is moved away from this maximum position until the ventilation flap 13 assumes a second maximum position (not shown), wherein, during this pivoting movement, the first ring 3 is actively braked again by the spring-loaded brake element 22. When in the second direction of rotation D, from reaching the other maximum position₂When the second ring 7 is rotated further upward, the braking force of the braking element 22 is overcome again, so that the first ring 3 together with the second ring 7 and thus with the ventilation flap 13 is rotated in the second direction of rotation D₂Rotating about the rotation axis D.
