Description

[0001] The invention relates to an air vent device for a ventilation system of a motor vehicle, comprising an air vent displaceably mounted on a support of the air vent device and having an outlet opening for discharging air in an outflow direction. The invention further relates to a method for operating an air vent device for a ventilation system of a motor vehicle and to a ventilation system of a motor vehicle.

[0002] For example, EP 0 792 764 A2 is known from the prior art. This document describes an air outlet for arrangement in a carrier having an outer surface extending around a carrier opening, the arrangement comprising: an outlet housing pivotally connected to the carrier at the carrier opening for movement between a closed position and an open position; and a cover attached to the outlet housing, extending substantially flush with the outer surface and covering the carrier opening in the closed position.

[0003] Furthermore, the document WO 2013 / 034679 A1 describes an air conditioning system for use in a motor vehicle, the air conditioning system comprising a controller, at least one primary vent opening, and an air supply device for arrangement in a dashboard of the motor vehicle, the device comprising: at least one secondary nozzle; and means for moving at least one secondary vent opening between a retracted position in which the secondary vent opening lies behind a surface of the dashboard and an extended position in which the secondary vent opening is exposed for delivering air to a region of the motor vehicle, the control device being operable to control the air conditioning system to provide an airflow from the primary vent opening while the air supply device is in a retracted position;and to control the at least one vent to assume the extended position when airflow is requested from the at least one secondary vent opening;

[0004] The object of the invention is to propose an air outlet device for a ventilation system of a motor vehicle, which has advantages over known air outlet devices, in particular enabling a needs-based and targeted ventilation of an interior of the motor vehicle.

[0005] This is achieved according to the invention with an air outlet device for a ventilation device of a motor vehicle with the features of claim 1. It is provided that the air outlet device has a deflection element and the air outlet is arranged in at least one position such that the deflection element is located in front of the air outlet in the outflow direction, so that the air emerging from the outflow opening strikes the deflection element.

[0006] Advantageous embodiments with useful further developments of the invention are specified in the dependent claims. It should be noted that the exemplary embodiments explained in the description are not limiting; rather, any variations of the features disclosed in the description, the claims, and the figures are feasible.

[0007] The air outlet device is preferably a component of the ventilation system of the motor vehicle, but can of course also be provided separately. The ventilation device serves to ventilate the interior of the motor vehicle, i.e., to supply air into the interior. For example, the air is taken by the ventilation device from an external environment of the motor vehicle and / or the interior of the motor vehicle itself. To introduce the air into the interior of the motor vehicle, the ventilation device has the air outlet device, to which air is supplied by the ventilation device, at least temporarily, and which subsequently enters the interior of the motor vehicle through the air outlet device, or more precisely, its air outlet.

[0008] The air vent device has an air vent, which is provided and designed to discharge air into the interior of the motor vehicle. The air vent is, on the one hand, fluidically connected to an air source and, on the other hand, at least temporarily adjacent to the interior of the motor vehicle. The air vent has an outlet opening through which air flows out, at least temporarily, and into the interior of the motor vehicle. The air flows out of the air vent through the outlet opening in the outlet direction. Preferably, a main flow direction of the air exiting through the outlet opening, i.e., the outlet direction, is used.For example, the outflow direction corresponds to a longitudinal central axis of the outflow opening and / or the outflow direction runs parallel to a surface normal of the outflow opening or is perpendicular to an imaginary plane which continuously intersects the center of an edge delimiting the outflow opening.

[0009] The air vent device is provided and designed to adjust the outflow direction of the air vent, namely by displacing the air vent. For this purpose, the air vent is mounted displaceably, namely on the support of the air vent device. The support is understood to be a basic element of the air vent device, which is arranged stationary with respect to the motor vehicle, for example. Alternatively, the support can of course also be displaceable with respect to the motor vehicle. Preferably, the air vent is displaceable by means of an actuator, in particular with respect to the support and / or the motor vehicle; for this purpose, the actuator is drive-connected to the air vent.

[0010] In order to create particularly versatile ventilation for the motor vehicle, the air outlet device has a deflection element in addition to the air outlet. The deflection element serves to deflect air that strikes it. For example, the deflection element is plate-shaped and can therefore also be referred to as a deflection plate or a baffle plate. The air outlet and the deflection element are arranged relative to one another in such a way that the outflow direction, or in at least one position of the air outlet, runs through the deflection element. Accordingly, the air escaping from the air outlet or its outflow opening strikes the deflection element and is deflected by it. The deflection element is arranged at a distance from the air outlet and its outflow opening.For example, the distance between the outlet opening and the deflection element is at least 100%, at least 200%, or at least 250% of the diameter of the outlet opening. The air flows from the outlet opening into the interior and only then encounters the deflection element, which overlaps the outlet opening for this purpose.

[0011] In any case, the outflow direction in at least one position is angled relative to the deflection element, i.e., forms an angle with the deflection element that is greater than 0° and less than 180°. Particularly preferably, the angle is at least 45° and at most 135°, at least 60° and at most 120°, at least 75° and at most 105°, or approximately or exactly 90°. Preferably, the outflow direction is therefore perpendicular to the deflection element or to an impact surface of the deflection element facing the air vent. When the air flowing out of the air vent strikes the deflection element, it is deflected and spread out.

[0012] For example, the deflection element can be arranged in a first position and a second position. In the first position, the outflow direction runs away from the deflection element; in the second position, the outflow direction separates from the deflection element, i.e., runs through it. Thus, the air flowing out of the air vent flows past the deflection element in the first position; in the second position, it encounters the deflection element and is deflected by it. Preferably, an air flow exiting the air vent device has a smaller diameter in the first position than in the second position, in which the air is fanned out by the deflection element.

[0013] In the first position of the air vent, the air flows past the deflection element; in particular, the air flow exiting the outlet opening is spaced from the deflection element. This allows the air to be directed very precisely to a specific location in the interior, for example to a person inside the vehicle. In contrast, in the second position of the air vent, the air hits the deflection element and then flows into the interior of the vehicle. This achieves very good distribution of the air in the interior and good air flow through the interior. The throw distance of the air vent device, i.e. the distance from the air vent device at which the air flow exiting the outlet opening influences the air in the interior, is smaller in the second position than in the first position.

[0014] A further development of the invention provides that the deflection element is mounted displaceably with respect to a frame, wherein the frame has an opening and the deflection element closes the opening at least partially in a first deflection element position and opens it in a second deflection element position. The frame serves in particular to connect the air outlet device to the motor vehicle, for example to an interior component of the motor vehicle. The interior component is, for example, a dashboard. The deflection element is displaceable with respect to the frame; for example, the deflection element is mounted displaceably on the frame directly or only indirectly, in particular via the support.

[0015] The opening is made in the enclosure, which closes the deflecting element at least partially, preferably completely, in its first deflecting element position. This means that the deflecting element is arranged in the opening or overlapping the opening in the first deflecting element position. In any case, the deflecting element preferably rests against an edge delimiting the opening, in particular continuously in the circumferential direction with respect to a longitudinal center axis of the opening. If the deflecting element is arranged in the opening, it preferably rests against the edge in a radially outward direction; if it is arranged outside the opening, it rests against the edge in an axial direction in order to close the opening at least partially or completely.

[0016] In its second deflection element position, however, the deflection element is arranged such that it opens the opening. For this purpose, it is arranged at a distance from the opening, at least in some regions, for example arranged completely parallel to the opening. Preferably, the air outlet device is designed such that the air flowing out of the air vent flows through the opening into the interior of the motor vehicle, or that the air vent reaches through the opening and projects through it into the interior of the motor vehicle, so that the air flowing out of the air vent flows directly into the interior. The described design of the air vent device implements a visually particularly unobtrusive arrangement of the air vent. For this purpose, the deflection element preferably only opens the opening if air is introduced into the interior of the motor vehicle by means of the air vent.

[0017] A further development of the invention provides that the air vent is mounted so as to be rotatable with respect to the support about at least one first axis of rotation and / or the support is mounted so as to be rotatable with respect to the frame about at least one second axis of rotation different from the first axis of rotation. Preferably, the air vent is mounted on the support so as to be rotatable about the at least one axis of rotation and / or the support is mounted on the frame about the at least one second axis of rotation. In particular, the air vent is only rotatable with respect to the support, so that the first axis of rotation is fixed with respect to the support. Analogously, it can be provided that the support is only rotatable with respect to the frame, so that the second axis of rotation is fixed with respect to the frame.

[0018] Preferably, the air vent is rotatable relative to the support about exactly a first axis of rotation. However, it can also be rotatable about several different first axes of rotation, wherein the first axes of rotation are, for example, angled to one another or skewed to one another. Analogously, the support can be mounted so as to be rotatable about exactly a second axis of rotation or about several second axes of rotation. In the latter case, the second axes of rotation are, for example, angled to one another or skewed to one another. The first axis of rotation and the second axis of rotation are different from one another, i.e. they do not coincide, but are arranged parallel and spaced from one another, intersect one another, or are skewed to one another.

[0019] It is particularly preferably provided that the second axis of rotation is angled with respect to an imaginary plane that completely accommodates the first axis of rotation, i.e. that it encloses an angle with the plane that is greater than 0° and less than 180°. Particularly preferably, the angle is at least 60° and at most 120°, at least 75° and at most 105°, or approximately or exactly 90°. If, within the scope of this description, reference is made to the at least one first axis of rotation or the first axis of rotation, the statements are equivalent. Explanations relating to the at least one first axis of rotation can be applied to the first axis of rotation, and statements relating to the first axis of rotation can be applied to the at least one first axis of rotation.This applies accordingly to the at least one second axis of rotation and the second axis of rotation; explanations for the at least one second axis of rotation are therefore applicable to the second axis of rotation, and explanations for the second axis of rotation are applicable to the at least one second axis of rotation.

[0020] The described configuration allows for flexible positioning of the air vent. The air vent is preferably mounted so that it can rotate about the first axis of rotation relative to the support, which in turn is mounted so that it can rotate about the second axis of rotation relative to the frame. Accordingly, in such a configuration, the air vent is mounted so that it can rotate about both the first axis of rotation and the second axis of rotation relative to the frame.

[0021] A further development of the invention provides that the deflection element is rigidly connected to the support or is displaceable relative to the support and / or the enclosure, in particular linearly and / or rotationally. In a first variant, the deflection element is rigidly connected to the support, i.e., is displaceable together with it, in particular exclusively. Alternatively, in a second variant, the deflection element can be displaced, namely relative to the support and / or the enclosure. In particular, the deflection element is displaceably mounted on the support and correspondingly displaceable relative to the enclosure.

[0022] However, it can also be provided that the deflection element is mounted so that it can be moved directly on the frame, thus bypassing the support. The deflection element is preferably linearly and / or rotationally movable and mounted accordingly. Regarding the possible deflection element positions, reference is made to the further explanations in this description. The ability of the deflection element to be moved together with the support or independently of the support or frame enables particularly flexible ventilation of the vehicle's interior.

[0023] A further development of the invention provides that the deflecting element, in a stagnation point present in the at least one position, has a projection projecting in the direction of the air vent. In the at least one position of the air vent, the outflow direction intersects the deflecting element or its stagnation surface at the stagnation point. The projection of the deflecting element is arranged at this stagnation point; it extends from the impact surface in the direction of the air vent. The projection is preferably designed to be axially symmetrical to the outflow direction. For example, the dimensions of the projection decrease in the direction of the air vent, in particular in the radial direction with respect to the outflow direction. For example, the projection is designed as a cone or truncated cone. With the help of the projection, a reliable deflection of the air is achieved, in particular in the radial direction with respect to the outflow direction.

[0024] A further development of the invention provides that the air vent is designed as a joint head of a ball joint. The use of the ball joint for mounting the air vent enables particularly free displacement of the air vent; in particular, the air vent is optionally mounted so as to be rotatable about more than one first axis of rotation. In addition to the joint head, the ball joint has a joint socket in which the joint head is rotatably arranged. Preferably, a fluidic connection of the air vent to an air inlet of the air vent device or the air source is established via the ball joint. For this purpose, corresponding flow channels are provided in the joint head and the joint socket, which are fluidically connected to one another in several positions of the air vent, such that the air vent or its outflow opening is fluidically connected to the air inlet.

[0025] A further development of the invention provides that the deflection element is mounted via a support element that is arranged at a distance from the air vent and / or partially surrounds the air vent. The support element serves in particular to connect the deflection element to the support, for example a rigid and / or a movable connection. Preferably, the support element is arranged such that it does not impede the air flowing out of the air vent. In particular, therefore, the support element is arranged away from the outflow opening or the outflow direction in every position of the air vent during normal operation of the air vent. For example, the support element is located behind the air vent.

[0026] It can be provided that the support element has increasing dimensions from the direction of the deflection element toward the air vent and / or the support. For example, the support element has two partial support elements that converge at the deflection element or in the area of the deflection element and diverge from each other toward the air vent, accommodating the air vent between them. This achieves a dimensionally stable and simultaneously visually appealing connection of the deflection element.

[0027] A further development of the invention provides that the support element has a joint and is designed such that, when a force is applied by the air vent, the deflection element is displaced into the second deflection element position. The support element and the air vent are arranged relative to one another and displaceable relative to one another such that the air vent at least temporarily rests against the support element and, via the support element, causes the deflection element to be displaced. For example, the air vent is initially arranged at a distance from the support element, and the deflection element is in the first deflection element position, in which it at least partially closes the opening in the enclosure.

[0028] The air vent is displaced toward the support element so that it rests against it and, via the support element, pushes the deflection element from the first deflection element position toward the second deflection element position, in particular into the second deflection element position. This is achieved using the joint, which is provided in the support element. The described design eliminates the need for a separate actuator for displacing the deflection element.

[0029] The invention also relates to a method for operating an air vent device for a ventilation system of a motor vehicle, in particular an air vent device according to one or more of the preceding claims, wherein the air vent device has an air vent displaceably mounted on a support of the air vent device and having an outflow opening for the outflow of air in an outflow direction. It is provided that the air vent device has a deflection element, and the air vent is arranged, at least temporarily, in at least one position in which the deflection element is located in front of the air vent in the outflow direction, so that the air exiting from the outflow opening strikes the deflection element.

[0030] The advantages of such a procedure and such a design of the air outlet device have already been pointed out. Both the air outlet device and the method for its operation can be further developed according to the explanations within the scope of this description, so reference is made to these in this regard.

[0031] A further development of the invention provides that the vent is displaced by means of an actuator such that the outflow direction corresponds to a desired outflow direction. If the current outflow direction, also referred to as the actual outflow direction, deviates from the desired outflow direction, the actuator is operated to adjust the actual outflow direction toward the desired outflow direction, in particular until the actual outflow direction corresponds to the desired outflow direction. The desired outflow direction is set, for example, by a user of the motor vehicle using a control element that is arranged in the interior of the motor vehicle and / or is at least accessible from the interior.

[0032] However, it can also be provided that the target outflow direction is selected as a function of person detection and / or seat occupancy detection. Particularly preferably, person detection is carried out in such a way that the position of a specific body part of a person in the interior of the motor vehicle is identified and the target outflow direction is selected such that it points in the direction of the position or intersects it. A face of the person, for example, is used as a body part. It can also be provided that the target outflow direction is periodically changed according to a predetermined course, so that the target outflow direction follows the course over time. This can, for example, achieve a "waving" of the air outlet.

[0033] The invention also relates to a ventilation device of a motor vehicle, comprising an air vent device, in particular an air vent device according to the embodiments within the scope of this description, wherein the air vent device has an air vent displaceably mounted on a support of the air vent device and having an outflow opening for discharging air in an outflow direction. It is provided that the air vent device has a deflection element, and the air vent is arranged in at least one position such that the deflection element is located in front of the air vent in the outflow direction, so that the air exiting from the outflow opening impinges on the deflection element.

[0034] With regard to the advantages of such a design of the ventilation device and possible advantageous designs, reference is again made to the explanations in this description.

[0035] A further development of the invention provides that the air outlet device is fluidically connected to an air source via a first outlet connection of a valve device, and that a further air outlet device is fluidically connected to a second outlet connection of the valve device. The valve device is designed such that the air provided by the air source can be distributed between the first outlet connection and the second outlet connection, i.e., ultimately between the air outlet device and the further air outlet device. In particular, in a first setting of the valve device, the air outlet device is fluidically connected to the air source, whereas the further air outlet device is fluidically decoupled from the air source.Conversely, in a second setting of the valve device, the air outlet device is fluidically decoupled from the air source, whereas the further air outlet device is fluidically connected to the air source.

[0036] For example, it is provided that the air outlet device is only used to discharge air when required. At least temporarily, therefore, air is only introduced into the interior of the motor vehicle via the additional air outlet device, and the air outlet direction is only temporarily used for the same purpose. The air outlet device and the additional air outlet device are preferably designed differently; in particular, the additional air outlet device does not have any mechanically adjustable elements, but is rather statically adjusted. With the help of the additional air outlet device, basic ventilation of the interior is ensured, whereas when required, the air outlet device takes the place of the additional air outlet device in order to ensure effective and targeted ventilation of the interior.

[0037] The features and feature combinations described in the description, in particular the features and feature combinations described in the following description of the figures and / or shown in the figures, can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the invention. Thus, embodiments are also considered to be encompassed by the invention that are not explicitly shown or explained in the description and / or the figures, but which follow from or can be derived from the explained embodiments.

[0038] The invention will be explained in more detail below with reference to the exemplary embodiments shown in the drawings, without limiting the invention. In the drawings: Fig. 1 a schematic representation of a ventilation device of a motor vehicle with an air outlet device in a first setting, Fig. 2 a schematic representation of the air outlet device of the ventilation device in a second setting, Fig. 3 a schematic representation of the air outlet device of the ventilation device in a third setting, and Fig. 4 a schematic representation of an area of a motor vehicle with the air outlet device.

[0039] The Fig. 1 shows a schematic representation of a ventilation device 1 of a motor vehicle 2 (not shown in detail). The ventilation device 1 has an air outlet device 3, by means of which air can be introduced into an interior 4 of the motor vehicle 2. The air outlet device 3 has an air vent 5 with an outlet opening 6, through which air can be discharged in an outflow direction 7 or introduced into the interior 4. The air vent 5 is rotatably mounted about an axis of rotation 8, namely with respect to a support 9. An actuator 10 is arranged on the support 9 and is drive-coupled to the air vent 5, in particular via a linkage 11. However, this connection is purely exemplary. Of course, the actuator 10 can also be connected to the air vent 5 in another way in order to rotate it about the axis of rotation 8.

[0040] In addition to the air vents 5, the air outlet device 3 has a deflection element 12, which is provided with a baffle surface 13 on its side facing the air vent 5. The deflection element 12 is coupled, in particular rigidly, to the support 9 via a support element 14. The deflection element 12 is displaceable together with the support 9 and, for this purpose, is mounted displaceably with respect to a frame 15. An opening 16 is formed in the frame 15, which opening is at least partially or completely closed by the deflection element 12 in the first deflection element position shown here.

[0041] The Fig. 2 shows a schematic representation of the ventilation device 1, wherein the air outlet device 3 is in a second setting. In this setting, on the one hand, the support 9 together with the air outlet 5 and the deflection element 12 are displaced such that the deflection element 12 exposes the opening 16 and the air outlet 5 protrudes through the opening 16 into the interior 4. On the other hand, the air outlet 5 is in a position in which the outflow direction 7 intersects the deflection element 12 and in particular the impact surface 13, in particular perpendicularly. This creates a stagnation point 17 on the deflection element 12, in which the deflection element 12 has a projection 18 that projects beyond the impact surface 13 in the direction of the air outlet 5. The deflection element 12 and its projection 18 cause a deflection of the air flowing out of the air outlet 5 in a radial direction with respect to the outflow direction 7, as indicated by the arrows 19.

[0042] The Fig. Figure 3 again shows a schematic representation of the ventilation device 1 with a third setting of the air outlet device 3. In this third setting, the support 9, the air outlet 5, and the deflection element 12 are, for example, arranged identically as before or—as shown here—displaced such that they protrude further through the opening 16 into the interior 4. Furthermore, the air outlet 5 is oriented such that the outflow direction 7 is away from the deflection element 12, i.e., does not intersect it. Accordingly, the air flowing out of the air outlet 5 does not impinge on the deflection element 12, or only to a small extent, but enters the interior 4 directly and in a targeted manner.

[0043] The Fig.Figure 4 shows an area of the motor vehicle 2, namely a dashboard 20, in which the air vents 3 are arranged. It is clear that, on the one hand, the air vent 5 is in the form of a joint head of a ball joint. On the other hand, it can be seen that the support element 14 has several partial support elements 21 and 22, which converge at the deflection element 12 and diverge from one another in the direction of the air vent 5. They are arranged such that they engage the support 9 on opposite sides of the air vent 5.

[0044] The described design of the ventilation device 1 enables the targeted introduction of air into the interior 4 of the motor vehicle 2. In particular, different ventilation modes can be implemented using the deflection element 12. In a first ventilation mode, in which the outflow direction 7 is away from the deflection element 12, a compact air jet is discharged into the interior 4. In a second ventilation mode, in which the outflow direction 7 runs through the deflection element 12, the air jet is fanned out, thus effectively ventilating a larger sub-volume of the interior 4.
