Abstract
Description
Technical Field
[0001] The invention relates to a ventilation device for ventilating the interior of a motor vehicle and to a motor vehicle having such a ventilation device. Background Art
[0002] Ventilation devices for ventilating the interior of a motor vehicle are known from the prior art (e.g., DE 10 2009 007 037 A1). Particularly popular here are ventilation devices with adjustable lamellae for deflecting the air flow in a targeted manner into the interior of the motor vehicle. Such ventilation devices usually have a ventilation duct with an air outlet or outflow opening and a plurality of vertical and horizontal lamellae arranged in the ventilation duct and adjustable in position, in order to deflect the air flow into the passenger compartment as precisely as possible.
[0003] Disadvantageously, known ventilation devices usually have a relatively large outlet opening for introducing the air flow, which is necessary in order to ensure the desired deflection angle of the air flow. However, large outlet openings are unsightly and it is difficult to integrate the ventilation device into the dashboard of a motor vehicle in an attractive design. In addition, large outlet openings are also disadvantageous in terms of installation space. Although systems are known from the prior art that attempt to at least partially solve the problems mentioned, these solutions are usually complex in design and include a large number of components, so that these systems do not constitute suitable alternatives for structural and cost reasons. Summary of the invention
[0004] The object of the present invention is therefore to at least partially eliminate the above-described disadvantages of a ventilation device for a motor vehicle. In particular, the object of the present invention is to provide a ventilation device for a motor vehicle for use which can be produced and operated in a structurally simple and cost-effective manner, has an externally attractive design, is compactly constructed and ensures a large deflection angle when introducing the air flow into the passenger compartment of the motor vehicle.
[0005] The above object is achieved by the patent claims. The object is therefore achieved by a ventilation device having the features of the independent claim 1 and by a motor vehicle having the features of the parallel claim 11. Further features and details of the invention are derived from the dependent claims, the description and the drawings. Here, the features and details described in conjunction with the ventilation device according to the invention are of course also applicable in conjunction with the motor vehicle according to the invention, and vice versa, respectively, so that the disclosures for the individual inventive aspects always refer to each other or can refer to each other.
[0006] According to the invention, a ventilation device is provided for ventilating the interior of a motor vehicle. The ventilation device according to the invention has a ventilation channel with an outflow opening of width and height, a plurality of vertical fins arranged in the ventilation channel for deflecting the airflow in the horizontal direction, an upper horizontal fin and a lower horizontal fin arranged in the ventilation channel for deflecting the airflow in the vertical direction. According to the invention, it is provided that the upper and lower horizontal fins can be rotated about a rotation axis in the ventilation channel and can be moved along a movement axis arranged perpendicular to the rotation axis.
[0007] Therefore, according to the invention, the ventilation device is designed to be manufactured in a structurally simple and cost-effective manner due to the arrangement of the upper and lower lamellae in the ventilation duct, which are rotatable about a rotation axis and movable along a movement axis arranged perpendicular to the rotation axis, and at the same time ensures a compact, externally attractive shape that enables a large deflection angle when introducing the air flow into the passenger compartment of the motor vehicle.
[0008] Due to the flexible and versatile mobility of the upper and lower horizontal lamellae provided, it is particularly possible to ensure, using the arrangement of the two horizontal lamellae, a large deflection angle when introducing the air flow into the passenger compartment of the motor vehicle and thereby simultaneously create a compact, outwardly attractive design which can also be manufactured simply and cost-effectively.
[0009] The ventilation device according to the present invention can preferably be arranged in the accessory area of a motor vehicle. Obviously, the ventilation device according to the present invention can be used not only in motor vehicles (such as passenger cars or trucks), but also in trains, trams, airplanes or ships. Here, the width of the specific outflow opening can preferably be greater than the height of the outflow opening. Obviously, the terms "horizontal" and "vertical" can be understood with respect to the orientation of the lamellae, especially with respect to each other, and not with respect to the vehicle axis. In this way, the ventilation device according to the present invention can be arranged in a rotating manner in a motor vehicle, for example, so that the lamellae may not be vertical or horizontal to the vehicle axis, but still be oriented horizontally and vertically to each other. Such an embodiment of the ventilation device should preferably also be included in the scope of protection of the present application. In addition, it is obvious that the vertical and horizontal lamellae can also be exchanged, for example, in the case of a 90° rotation of the ventilation device according to the present invention, which should preferably also be included in the scope of protection of the present application. In addition, it is obvious that the orientation according to the present invention may deviate slightly from the perfectly horizontal and vertical position, for example, deviate by a corresponding 5%, which should preferably still be included in the scope of protection of the present application.
[0010] In view of a structurally simple embodiment for ensuring the exact adjustability or positionability of the air flow for introduction into the interior of the motor vehicle, it can advantageously be provided according to the invention that the upper and lower horizontal lamellae can be rotated independently of one another about a rotation axis and / or can be moved independently of one another along a displacement axis arranged perpendicular to the rotation axis. Independent rotatability or displacement here means, in particular, that only one lamella is adjustable in its position and the other lamella remains in its position.
[0011] As part of a particularly fast and structurally less complex adjustment of the airflow, it can also be alternatively provided that the upper and lower horizontal lamellae can be kinematically coupled to rotate about an axis of rotation and / or can be kinematically coupled to move along an axis of displacement arranged perpendicular to the axis of rotation, wherein the kinematically coupled rotation about the axis of rotation and / or the kinematically coupled movement along the axis of displacement of the upper and lower horizontal lamellae are carried out in opposite directions to one another. In this case, in order to ensure the kinematic coupling of the movement of the upper and lower lamellae, a coupling element or the like can preferably be provided, which is arranged between the upper and lower lamellae.
[0012] In order to efficiently guide the air flow into the interior of the motor vehicle, it can also be provided according to the invention that the upper and lower horizontal lamellae have a curved shape, wherein the upper and lower horizontal lamellae are preferably designed to be curved toward each other and are arranged in the ventilation duct.
[0013] With a view to an embodiment which is structurally simple to produce while minimizing the number of components involved, it is in particular also conceivable to limit the number of provided horizontal lamellae to upper and lower lamellae.
[0014] Likewise, with a view to an embodiment which is structurally simple to produce while minimizing the number of components involved, it can be advantageously provided according to the invention that at least three, preferably more than three, vertical lamellae are arranged in the ventilation channel.
[0015] Within the scope of a particularly comfortable embodiment of the ventilation device for introducing an air flow, it is further conceivable that the upper and lower horizontal lamellae are continuously rotatable about an axis of rotation and / or are continuously displaceable along a displacement axis arranged perpendicular to the axis of rotation.
[0016] Likewise, in view of a structurally simple to manufacture embodiment for ensuring the precise positionability of the airflow in the interior space of a motor vehicle, it can be provided that the upper and lower horizontal lamellae can be rotated about a rotation axis in predetermined or predeterminable steps and / or can be moved along a movement axis arranged perpendicular to the rotation axis in predetermined or predeterminable steps.
[0017] Within the scope of the flexible and diverse operation of the ventilation device according to the invention, it can specifically be provided that the vertical lamellae and / or the upper and lower horizontal lamellae can be rotated manually and / or motorized about a rotation axis and / or can be moved manually and / or motorized along a movement axis arranged perpendicular to the rotation axis.
[0018] With a view to a structurally simple to produce embodiment for ensuring the exact positionability of the air flow in the interior of the motor vehicle, it is furthermore conceivable to provide sliding guides for adjusting the vertical lamellae and / or the upper and lower horizontal lamellae.
[0019] Likewise, the subject matter of the invention is furthermore a motor vehicle, which comprises the ventilation device described above. The motor vehicle according to the invention therefore has the same advantages as those which have already been described in detail with respect to the ventilation device according to the invention.

[0028] Here, the upper and lower horizontal lamellae 10 a , 10 b can be rotated about a rotation axis D independently of one another and / or can be moved along a displacement axis V arranged perpendicular to the rotation axis D independently of one another.
