Description

Ventilation device for a vehicle and method for ventilating a passenger compartment of a vehicle

Technical Field

The present invention relates to a ventilation device for a vehicle according to the preamble of claim 1 and a method for ventilating a vehicle according to the preamble of claim 17.

Background

Such a ventilation device comprises at least one outflow opening for generating an air flow. At least one outflow opening can be arranged on an interior structural component of the vehicle. The ventilation device further comprises at least one covering member for covering the interior space structural assembly. The air flow can flow through the at least one cover element from the at least one outflow opening.

Such a ventilation device can be, for example, a structural component in the cockpit or rear of the vehicle, in particular a structural component on the dashboard or console (e.g. center console) or on the seat. At least one outflow opening can, for example, be opened by an outflow opening facing the person

Towards the personnel head-on flow

An outflow opening of the air channel or an air outlet nozzle. For example, air may be directed from an apparatus for heating, ventilation, and air conditioning (HVAC) to at least one outflow port. To this end, the at least one outflow opening can be connected to an HVAC device.

For example, the interior spatial structure components may include one or more of: steering column, mechanical and/or electronic component, loudspeaker, airbag, vehicle computer, HVAC equipment, glove compartment, storage compartment or frame of a car seat. The at least one cover member may be configured for covering the interior spatial structural assembly with respect to an occupant of the vehicle. To this end, the at least one covering member may visually conceal the interior spatial structural assembly. In particular, the at least one cover member may conceal the mechanical and/or electrical components.

For example, the air flow may be able to flow from the at least one outflow opening into the passenger compartment of the vehicle. The passenger compartment may be a space within the vehicle, in which the occupants are arranged as desired within the vehicle. The at least one outflow opening can let the air flow into the passenger cabin, for example in the direction of the front windshield, in the direction of the footwell or in any direction between the front windshield and the footwell. In particular, the at least one outflow opening may cause the air flow to flow in the direction of an occupant seated as intended in the vehicle.

Proceeding from the at least one outflow opening, the air flow can pass through the at least one covering element. For this purpose, the air flow can flow out of the at least one outflow opening and, for example, into the passenger compartment through an opening in the at least one covering element. The at least one outflow opening can thus be set up for the air flow through the opening in the at least one cover element. The air flow can also flow into the passenger compartment, for example into the footwell, for example by way of at least one outflow opening, alongside the edge region of at least one covering element. In principle, therefore, at least one section of the at least one outflow opening, and in particular also the HVAC system, is covered with the at least one covering element relative to the passenger cabin and/or an occupant seated in the vehicle as intended. From the point of view of the occupant, the at least one outflow opening or at least one section of the at least one outflow opening can be concealed behind the at least one cover member.

It is known to redirect the air flow by manually adjusting slats. For example, an occupant seated as intended in the vehicle can direct the air flow towards its head, i.e. in the direction of the head part of the backrest of the vehicle seat, by manually adjusting the slats.

US 2017/253107 a1 describes a ventilation device in which the orientation of the slats can be changed by making user inputs on the touch screen.

DE 102006016278B 3 describes a ventilation device in which an outflow opening is integrated into a covering element, so that an air flow can flow out of the outflow opening directly into the passenger compartment. This results in a smooth surface, but the outflow opening still spoils the appearance.

It is desirable to design the vehicle interior as an outflow opening without visual interference and without devices and operating elements for redirecting the air flow.

Disclosure of Invention

The object of the invention is to provide a ventilation device for a vehicle and a method for ventilating a vehicle, which device and method enable an advantageous redirection and/or shaping of the air flow without affecting the design of the vehicle interior space.

This object is achieved in particular by a ventilation device according to claim 1 and a method according to claim 17.

According to a first aspect, the ventilation device has a regulating device. With the adjusting device, the at least one outflow opening and/or the at least one cover element can be adjusted for redirecting and/or shaping the air flow.

The direction of the air flow can thus be adjusted in particular without the use of slats. The air flow can thus be redirected only with the use of at least one outflow opening and/or at least one cover member. This has the advantage that the at least one outflow opening can be arranged to be covered by the at least one cover member. Thus, for example, neither the at least one outflow opening nor the slats disturb the appearance of the interior space of the vehicle. The appearance of the vehicle interior in the section which causes the air flow to flow into the passenger compartment can be determined solely by the at least one covering element. In particular, the ventilation device may be suitable for an instrument panel having a coherent air supply gap between the driver seat and the passenger seat. The air supply slit may in particular be arranged above the baffle.

In one embodiment, the at least one cover element is formed over a large area. The at least one cover member may extend, for example, between a passenger compartment and a windshield of the vehicle. Also, the at least one cover member may define a foot well of the vehicle. In one embodiment, the at least one cover element extends over a large area transversely to the direction of travel of the vehicle. In one embodiment, the at least one covering element can cover the interior space structure component with a first, planar surface. The second plane of the at least one cover element may face the passenger cabin. In one embodiment, the planar surface of the at least one cover element, in particular the second planar surface, is a surface section of the dashboard part.

The at least one cover member may define a structural space within which the interior space structural assembly can be disposed. In particular, at least one covering element can be provided for separating the interior space structural assembly from the passenger cabin. At least one outflow opening can be arranged in the installation space delimited by the at least one covering element. The air flow can flow from the at least one outflow opening over the at least one cover element through a cross-sectional area, the size of which can be adjusted by adjusting the at least one cover element and/or the at least one outflow opening using the adjusting device. In particular, the at least one outflow opening may not be arranged in a channel for guiding the air flow, but may be arranged at any position on the interior spatial structural component. In particular, a plurality of outflow openings can be arranged at any desired position on the interior space structure component.

In one embodiment, the air flow from the at least one outflow opening does not flow through the slats or past the slats. The ventilation device may be completely free of slats. In particular, the air flow can flow past the at least one covering element in an undivided manner starting from the at least one outflow opening. In ventilation devices with slats arranged in the air flow for redirecting the air flow, the air flow is divided at the slats, since the slats block the air flow in sections. In particular, the slats will cut through the cross-section of the air flow. In contrast, the undivided air flow may be more uniform and directed better, so that the ventilation provides greater comfort to the vehicle occupants. Furthermore, the arrangement of the slats on the dashboard disturbs the appearance. Even when the air flow can bypass the at least one covering element in an undivided manner, it is of course not excluded that the air flow can additionally be slowed down or accelerated, for example by the at least one covering element, in a widened, concentrated or segmented manner along its cross section.

In principle, the at least one outflow opening can be adjusted within an arbitrary adjustment range for redirecting the air flow. For example, the at least one outflow opening may be pivotable about a swing axis. In order to adjust the at least one outflow opening by means of the adjusting device, the adjusting device can have an electric adjusting motor for the at least one outflow opening in one embodiment. In particular, the at least one outflow opening may thus be electrified.

Likewise, the at least one outflow opening can have a nozzle plate or a slat. The air flow can be discharged from the at least one outflow opening through a nozzle plate or a slat. The nozzle plate or the slats may be adjustable by means of an adjusting device. In particular, the nozzle plate can be pivotable about an axis supporting the nozzle plate on the at least one outflow opening by means of an adjusting motor for the nozzle plate. Similarly, the slats can each be pivotable about an axis which supports the slats on the at least one outflow opening. In principle, the slats can be mounted so as to be rotatable about the longitudinal axis of the at least one outflow opening for redirecting the air flow in any spatial direction.

By adjusting the at least one outflow opening, the air flow can be redirected, for example, within a certain angular range. In principle, the angular range may at least comprise any spatial direction in the hemisphere in the direction of the passenger cabin. In particular, the angular range may extend vertically. The upper section of the angular range may then correspond, for example, to redirecting the air flow in the direction of the vehicle roof. The lower section of the angular range may correspond to redirecting the air flow in a direction towards the vehicle floor. Also, the angular range may be arranged horizontally. For example, a first segment of the angular range may correspond to redirecting the air flow in a direction toward a first side of the vehicle. The second section of the angular range may correspond to redirecting the air flow in a direction toward a second side of the vehicle opposite the first side.

In principle, the at least one covering element can be adjustable in all spatial directions for redirecting and/or shaping the air flow. For adjusting the at least one cover member, the adjustment device may comprise an adjustment motor for the cover member. For example, the cover member may be movable away from or towards the at least one outflow opening for shaping the air flow in a concentrated or broadened form. To this end, the air flow may flow through openings in the at least one cover member. A movement of the at least one cover element, in particular of the opening, in the direction of the at least one outflow opening can lead to a widening of the air flow. Conversely, a movement of the at least one cover member, in particular of the opening, away from the at least one outflow opening can result in a concentration of the air flow.

In one embodiment, the air flow can be by-passed the edge of the at least one cover member. Adjusting the at least one cover member in the direction of the air flow may result in a redirection in the form of a deflection of the air flow in the direction of the at least one cover member. Additionally, the air flow may be shaped in such a way that the air flow is slowed down and/or widened on the at least one cover member depending on the positioning of the at least one cover member relative to the adjustment of the air flow.

The air flow may be deflected at the at least one cover member, for example due to a coanda effect. The at least one cover element can be designed to deflect the air flow at least in sections along the surface of the cover element by means of the coanda effect. The coanda effect is understood to be the tendency of an air stream to follow a flow over a surface. The coanda effect may result in the air flow not being pulled off the surface. In particular, the coanda effect may cause the air stream to flow in a different direction after encountering the at least one cover member than before.

The use of an adjusting device for adjusting the at least one cover element for redirecting and/or shaping the air flow can have the advantage that the air flow can be deflected over a relatively large area compared to the air flow being redirected only by the at least one outflow opening. This is because in one embodiment the at least one outflow opening is limited in its adjustment range by the fact that it is hidden behind the at least one covering member. For example, the adjustment travel towards the passenger flow outlet, which is concealed in the instrument panel, is small, because the instrument panel limits the adjustment travel.

In one embodiment, the at least one cover member is vertically movable relative to the at least one outflow opening. Thus, the at least one cover member may in particular be moved into the air flow. The at least one cladding component can also be mounted so as to be pivotable about a pivot axis. With the adjusting device, the at least one cover member may be pivotable into the air flow for redirecting the air flow.

The at least one outflow opening or a component of the at least one outflow opening may thus be adjustable with the adjusting device for redirecting and/or shaping the air flow and/or the at least one cover member may in particular be movable or pivotable for exploiting the coanda effect.

In one embodiment, the at least one outflow opening may be adjustable with respect to the at least one cover member with an adjustment device for redirecting and/or shaping the air flow. For example, for shaping, the at least one outflow opening may be adjustable towards or away from an opening in the at least one cover member. The at least one outflow opening may also be adjustable with an adjusting device relative to the rim of the at least one cover member for redirecting and/or shaping the air flow.

In principle, the at least one outflow opening and the at least one cover member can also be jointly adjustable. In particular, the at least one outflow opening and the at least one cover member can be coupled to each other in order to achieve a combined adjusting movement for redirecting and/or shaping the air flow.

In one embodiment, the ventilation device has control electronics. The adjustment position of the at least one outflow opening can be settable by means of the control electronics. Alternatively or additionally, the adjustment position of the at least one cover member may be settable with control electronics. The adjustment of the positioning can comprise, for example, a positioning in space and/or an angle. The control electronics can thus for example be set up for setting the angle by which the at least one cover member is pivoted about the pivot axis, the angle by which the at least one outflow opening is pivoted about the axis, the angle by which the nozzle plate of the at least one outflow opening is pivoted about its axis supported on the at least one outflow opening and/or the angle by which the slats are pivoted about their axes supported on the at least one outflow opening, respectively. The control electronics can also be set up for setting the positioning of the at least one cover member relative to the air flow. This may include, for example, the distance of the at least one cover member from the air flow.

To set the adjustment setting, the control electronics can be coupled to the adjustment device. Thus, by setting the adjusted positioning of the at least one outflow opening and/or the at least one cover member, the direction and/or shape of the air flow can be set by the control electronics. In particular, the control electronics can be set up for automatically setting the direction and/or shape of the air flow, in particular also the air quantity flowing out through the at least one outflow opening. Thereby allowing air to be automatically distributed within the vehicle. The control electronics can in particular comprise software which contains executable instructions for setting the adjusting position, so that air can be distributed optimally in the vehicle.

In one embodiment, the control electronics are set up for redirecting and/or shaping the air flow in dependence on characteristics or setting parameters of the vehicle occupant. For example, the control electronics may include a memory device. The memory device may be arranged for storing setting parameters for redirecting and/or shaping the air flow for different occupants, so that the control electronics may redirect and/or shape the air flow depending on its stored setting parameters when the occupant is using the vehicle. In one embodiment, the control electronics are coupled to a determination device, with which the characteristics of the occupant can be transmitted to the control unit. Such features may be, for example, the size of the occupant or the thickness of the occupant's clothing, such as a lightweight summer clothing or a heavy winter clothing. For example, the control electronics can be set up for redirecting the air flow to a higher location on the head of a higher occupant, or to set a concentrated air flow to an occupant wearing heavy winter clothing, for example.

In one embodiment, the control electronics can be coupled with a seat adjustment for setting the configuration of the vehicle seat. The configuration of the vehicle seat may for example comprise the height of the vehicle seat relative to the vehicle floor, the inclination of the backrest of the vehicle seat and/or the distance of the vehicle seat from the at least one outflow opening. The control electronics can be set up for setting the adjustment position of the at least one outflow opening and/or of the at least one cover member in dependence on the configuration of the vehicle seat. Thus, depending on the configuration of the vehicle seat, the control electronics can set the direction and/or shape of the air flow. This may have the advantage that, for example, a vehicle occupant who has adjusted the backrest backwards does not have to bend forward in order to adapt the direction of the air flow as intended. Since the control electronics can automatically set the changed adjustment position of the at least one outflow opening and/or of the at least one cover member as a setting parameter of the configuration of the vehicle seat is changed by the seat adjustment. Thus, the at least one outflow opening does not have to be accessible to the occupant.

In one embodiment, the angle at which the air flow can flow into the passenger compartment and/or the degree of turbulence of the air flow can be controlled by adjusting the at least one outflow opening and/or the at least one covering element. In particular, the control electronics can be set up for setting the angle and/or the degree of turbulence by setting the adjusted positioning of the at least one outflow opening and/or the at least one cover member.

For example, the angle may be controllable by pivoting the at least one outflow opening. The at least one outflow opening can thereby direct the air flow out at a set angle into the passenger compartment. Also, the angle may be controllable by moving the at least one outflow opening relative to the at least one cover member. The angle at which the air flow can flow into the cabin can be controlled by the degree of deflection of the air flow at the at least one covering element. The at least one cover member may also be adjustable, in particular pivotable and/or movable, relative to the at least one outflow opening, such that by adjusting the at least one cover member relative to the at least one outflow opening, the degree of deflection of the air flow at the at least one cover member can be controlled. Thus, redirecting the air flow by adjusting the at least one outflow opening and/or the at least one covering member may in particular comprise the angle at which the air flow can flow into the cabin. The angle can be determined in this case, as appropriate, relative to a driving direction vector which allows the vehicle to travel in a normal forward direction.

In particular, the degree of turbulence of the air flow may indicate how much turbulence the air flow contains. In particular, the degree of turbulence may indicate whether the air flow is laminar (low turbulence) or diffuse (high turbulence). Controlling the degree of turbulence of the air flow is of great importance to the comfort of the occupants of the vehicle in using the ventilation device. For example, while laminar air flow may cool or heat the head region of an occupant more quickly and more strongly, it may be perceived as quite uncomfortable over extended periods of use. In contrast, the diffused air flow may be less concentrated and may, for example, cool or heat the head region of the occupant more slowly or less strongly. Thus, the occupant may feel more comfortable when using the diffused airflow for a longer period of time. For example, the air flow can be switched from laminar to diffuse in a targeted manner by adjusting the at least one outflow opening and/or the at least one cover member.

By adjusting the at least one outflow opening relative to the at least one cover member, the degree of turbulence of the air flow may be controllable as a result of the air flow being slowed down and/or redirected in sections with respect to the cross section of the air flow. By slowing down the sections of the cross section of the air flow, turbulence may be created due to the mixing of the slowed and non-slowed sections, causing the air flow to widen and/or swirl as a whole. An adjustment of the at least one cover member relative to the at least one outflow opening or an associated movement of the at least one outflow opening and the at least one cover member may lead to the same result.

Thus, an element of the instrument panel in the form of at least one covering element can be used for air distribution and/or air conditioning. The air flow can flow out of the at least one outflow opening, for example in a laminar manner, and it can also be controllable in its angle or its degree of turbulence by only sectional contact with the at least one covering member. In particular, the control of the angle at which the air flow can flow into the cabin can be achieved by deflection of the air flow on the at least one covering element due to the coanda effect. Thus, the angle control and the turbulence level control of the air flow can be performed independently of each other in this respect.

In one embodiment, the at least one outflow opening is hidden by the at least one cover member in a state of being mounted in the vehicle as intended, from the perspective of an occupant seated in the vehicle as intended. Thus, the at least one outflow opening may be hidden behind the at least one cover member. The at least one cover member may thus at least limit the visibility of the at least one outflow opening from the outside, for example by means of a contour of the at least one cover member. The concealment of the at least one outflow opening by the at least one cover member can be achieved, for example, by arranging the cover member in the line of sight between the occupant and the at least one outflow opening.

In one embodiment, the at least one outflow opening is configured to direct an air flow towards a surface of the at least one cover member. Whereby the air flow can flow along the surface. In particular, the air flow may follow the contour of the at least one covering member. In one embodiment, the control electronics are set up for setting an adjustment position of the at least one outflow opening, in which an air flow is directed onto a surface of the at least one cover member. The fact that the at least one outflow opening is configured for directing the air flow onto the surface may mean that a direction vector of the air flow out of the at least one outflow opening is directed towards the surface.

The section of the surface along which the air flow can flow into the passenger cabin can be formed convexly and/or angularly. The at least one cover member may be contoured to divert the air flow. The convex configuration of the surface section may be usable for redirecting the air flow in the direction of the at least one cover member, in particular with the use of the coanda effect. The angled, in particular acute-angled or concave, configuration of the surface section can be used to redirect the air flow away from the at least one cover element.

In one embodiment, at least the section of the surface along which the air flow can flow into the passenger cabin is elastically constructed. In principle, the at least one cover member may be formed entirely of an elastic material, in particular an elastic. The ventilation device can have an adjusting element with which the angle and/or the curvature of the elastic section can be changed. In order to change the angle and/or curvature of the elastic section, the adjusting element can be adjustable, for example, by means of an adjusting device and in particular by means of an adjusting motor for the adjusting element of the adjusting device. The at least one cover member may thus be movable or pivotable with the adjusting device, for example relative to the at least one outflow opening, for redirecting and/or shaping the air flow. As an alternative or in addition thereto, since the adjusting element is adjusted with an adjusting device, the at least one cover member may be adjustable with an adjusting device for redirecting and/or shaping the air flow. The adjusting element may thus be adjustable with the adjusting device for redirecting and/or shaping the air flow.

For example, adjustment of the adjustment element may result in the formation, expansion, contraction or movement or pivoting of the angle or curvature of the resilient section of the surface.

In one embodiment, the at least one cover member is pivotable with the adjustment device to release the first air supply slit or the second air supply slit for the flow of the air flow depending on the adjusted positioning of the at least one cover member. The at least one cover element can thus be set up for releasing the at least two blowing slots as an alternative depending on the adjustment position.

At least two air supply gaps can be formed between the at least one cover element and further components of the ventilation device or of the vehicle. For example, the air flow may be formed by a blowing gap between at least one cover member and another cover member of the ventilation apparatus.

In order to release the at least two blowing slots, the at least one cover member can be pivoted about a pivot axis. The axis of oscillation may extend parallel to the vehicle floor. In particular, in the intended installation state of the ventilation device, the pivot axis can be arranged parallel or transverse to the intended direction of travel of the vehicle. In principle, the at least one cover member can also be moved along an axis parallel or transverse to the intended direction of travel of the vehicle in order to release the at least one first or second air supply gap for the air flow depending on the adjusted positioning of the at least one cover member. The at least one cover element can also be movable along an axis which extends perpendicular to the vehicle floor in the intended installation state of the ventilation device. Depending on the adjusted positioning of the at least one cover element, the air supply gap for the flow of the air flow can then be opened or closed.

In one embodiment, the at least one cover member is pivotable between at least a first adjustment position and a second adjustment position. In the at least one first adjustment position, the at least one cover member may release the first air delivery slit to cause airflow in a direction of an occupant of the vehicle. In the at least one second adjustment position, the at least one cover member may release the second air supply slit to cause the air flow to flow in a direction of a windshield of the vehicle. The air flow may thus be directed towards, for example, an occupant or a windshield depending on the adjusted positioning of the at least one cover member. Additionally or alternatively to this, the pivoting of the at least one cover member may be usable for redirecting and/or shaping the air flow.

In one embodiment, the ventilation device comprises a winding element. At least one cover member may be disposed on the winding element. In particular, at least one section of the at least one covering member may be formed from an elastic material, in particular an elastic. The at least one covering member may be windable on the winding element for redirecting and/or shaping the air flow. The at least one cover member may be adjustable relative to the at least one outflow opening via a winding element. In particular, the wound at least one cover member can be adjustable into the air flow flowing out of the at least one outflow opening by a winding movement of the winding element, so that the air flow is redirected and/or shaped by the wound at least one cover member. In principle, the winding element can be adjustable by means of an adjusting device. The control electronics can also be set up to set the adjustment position of the winding element.

In another embodiment, the ventilation device has two cover members which are adjustable relative to one another. This arrangement of the cover elements relative to one another may define a supply air gap through which an air flow can flow into the passenger cabin. Therefore, the air flow can flow into the passenger compartment through the air supply gap between the cover members. In one embodiment, a first of the two cover members is arranged on the winding element. The first cover member may be adjustable with respect to a second of the two cover members using the wrapping element. In particular, the first cover member may be windable with the winding element such that the distance between the cover members is enlarged. The size of the air blowing slit may thus be changeable by the winding of the first cover member. In particular, the air supply slit may be closable by unfolding the first cover member. Of course, in principle both cover members may be separately windable on the winding element.

The winding element can be configured for giving the at least one wound covering member a cambered shape, so that the air flow is deflected along the surface of the wound section of the at least one covering member, in particular using the coanda effect. In particular, the winding element may give the at least one covering member to be wound a convex shape.

In one embodiment, the opposing surfaces of the two cover members are shaped for fanning out the air flow at the two cover members. After the air flow has passed by the two cover elements, the air flow can have a narrower cross section than when flowing out of the at least one outflow opening. The cross section of the air flow can thus be widened as a result of the air flow passing by the two cover elements. In particular, a first component of the air flow may be streamable over the first cover member and a second component of the air flow may be streamable over the second cover member. The first and second components of the air flow may in particular be streamable over the opposing surfaces of the two cover members. The opposed surfaces of the two cover members may be shaped to deflect the first component in a direction opposite to the second component. In particular, the first component may be deflected in the direction of the first cover member, while the second component may be deflected in the direction of the second cover member. In principle, the first and second components are edge components of the air flow which lie on the edges of the air flow. At least one third component may be arranged in the center of the air flow. In principle, the at least one third component is not deflected by the cover member. The first, second and at least one third component may together load the fan-shaped air flow into the passenger compartment.

In one embodiment, the ventilation device has at least one pointing element. The at least one pointing element may be arranged on the at least one cover member. The at least one pointing element may be adjustable relative to the at least one cover member for redirecting and/or shaping the air flow. In particular, the at least one pointing element may be adjustable with an adjustment device. The at least one pointing element may be adjustable into the trajectory of the air flow flowing out of the at least one outflow opening. In one embodiment, the control electronics are set up for setting the adjustment position of the at least one pointing element.

The at least one directional element can in principle be formed convexly and/or angularly with respect to the air flow. The contour of the at least one pointing element on which the air flow impinges may be usable for redirecting the air flow. The convex configuration of the at least one pointing element can be used to redirect the air flow in the direction of the at least one pointing element, in particular using the coanda effect. The angled, in particular acute-angled or concave, formation of the at least one pointing element can be used to redirect the air flow away from the pointing element.

In one embodiment, the at least one pointing element is configured as a decorative strip. The at least one pointing element may in particular be a stainless steel baffle.

The object of the invention is also achieved by a method for ventilating a vehicle. According to this second aspect of the proposed solution, the passenger compartment of the vehicle is ventilated with an air flow. The air flow flows past the at least one cover element starting from the at least one outflow opening. At least one cover member is used to cover an interior space structural assembly of the vehicle. The air flow is bypassed at least one cover member into the passenger compartment. The method is applicable to the ventilation device according to the first aspect of the proposed solution, but is not limited thereto.

The air flow is redirected and/or shaped by adjusting the at least one outflow opening and/or the at least one cover member. For example, the air flow can be redirected by changing the angle at which the air flow flows into the cabin by adjusting at least one outflow opening and/or at least one covering element. For example, the air flow may be shaped in such a way that the degree of turbulence of the air flow is changed. For example, the degree of turbulence may be increased by adjusting the at least one outflow opening and/or the at least one cover member. In particular, the at least one cover member may be brought into contact with the air flow by adjusting the at least one outflow opening and/or the at least one cover member itself such that the air flow flows along a surface of the at least one cover member.

To improve the comfort of the vehicle occupants, the air flow may be redirected depending on the configuration of the vehicle seat to which the air flow is directed. For example, the air flow may be directed towards a fixed part of the vehicle seat, such as a headrest. When the vehicle seat is adjusted, i.e. the configuration of the vehicle seat is changed, then the direction of the air flow can be adapted accordingly, so that the air flow is directed to the fixed location even after the vehicle seat has been adjusted.

Detailed Description

Fig. 1 shows a ventilation device for a vehicle having an interior space structural assembly I. The outflow opening 21 is arranged on the interior space structure component I. The outflow opening 21 produces an air flow L directed in the direction of the passenger cabin Z in which the vehicle seat S is arranged. Of course, a plurality of vehicle seats S can also be arranged in the passenger cabin Z. The interior space structural assembly I is covered with a covering element 22, so that the interior space structural assembly I is concealed from the passenger cabin Z by the covering element 22. The cover element 22 also covers the outflow opening 21 with respect to the passenger cabin Z. The air flow L can flow past the covering element 22 starting from the outflow opening 21. The air flow L flows out of the outflow opening 21, bypasses the covering element 22 and flows into the passenger cabin Z here or thereafter. The passenger cabin Z may thus be delimited by the covering element 22.

The ventilation device further comprises an adjusting device 1 with which the outflow opening 21 and the covering member 22 can be adjusted. For this purpose, the adjusting device 1 is coupled with the outflow opening 21 and the cover member 22. The adjusting movement of the outflow opening 21 and the cover member 22, respectively, is illustrated by a double arrow. Thus, the outflow port 21 and the cover member 22 can pivot vertically. Vertical may mean that the outflow opening 21 and the covering member 22 are pivotable between an adjusted position closer to the vehicle floor and an adjusted position closer to the vehicle roof. In principle, the outflow opening 21 and the cover member 22 can of course be adjustable in any spatial direction or can be pivotable about any pivot axis.

The individual or joint adjustment of the cover member 22 and the outflow opening 21 results in the air flow L being redirected and/or shaped. For example, the angle W at which the air flow L flows into the passenger cabin Z can be adapted by an adjustment of the covering element 22 and/or the outflow opening 21. Thereby also matching the shape of the air flow L. For example, the laminar air flow L may be swirled by adjusting the cover member 22 into the air flow L or by directing the air flow L toward the cover member 22.

The adjusting device 1 comprises control electronics 10 with which the adjusting positioning of the outflow opening 21 and the covering member 22 can be set. The adjustment positioning comprises a setting parameter of the angle W, X of the cover member 22 and/or the outflow opening 21. In principle, the adjustment positioning can comprise setting parameters of any positioning in space and/or any degree of pivoting about any pivot axis. The air flow L can thus be automatically redirected and/or shaped with the aid of the control electronics 10. In one embodiment, it is therefore not required for the occupant P of the vehicle to interact with the ventilation device, in particular with the regulating device 1 or the control electronics 10, in order to redirect and/or shape the air flow L.

The vehicle seats S in the passenger cabin Z include seat adjusting portions V, with which the arrangement of the vehicle seats S can be set. For exemplary explanation, configuring includes adjusting the backrest E of the vehicle seat S between an upright position and a lie-flat position. The control electronics 10 are coupled with the seat adjusting part V. Thereby, the control electronics 10 can be set up for taking into account the configuration of the vehicle seat S when setting the adjustment positioning of the outflow opening 21 and/or the cover member 22. Depending on the configuration of the vehicle seat S, the adjusting position of the outflow opening 21 and/or the covering member 22 can thus be set by the control electronics 10. In particular, the control electronics 10 may set the outflow opening 21 and/or the cover member 22 depending on the positioning of the backrest E. For a lying position, the control electronics 10 can set a flatter angle for the air flow L by, for example, pivoting the outflow opening 21 in the direction of the vehicle floor. For upright positioning of the backrest E, the control electronics 10 can set a steeper angle for the air flow L by, for example, pivoting the outflow opening 21 in the direction of the vehicle roof. In this way, the air flow L can be maintained, for example, to the headrest section of the backrest E, irrespective of the positioning of the backrest E.

In further embodiments, the control electronics 10 may pivot the cover member 22 away from the air flow L to shape the laminar air flow L when the backrest E is adjusted into the lie-flat position. In this way, for example, the air flow L can reach the headrest section of the backrest E that is spaced further from the outflow opening 21 in the lying position. When the seat back E is adjusted into the upright position, the control electronics 10 may be set up to pivot the cover member 22 into the air flow L to increase the degree of turbulence in the air flow L. In this way, in the upright position of the headrest section of the backrest E, which is spaced closer to the outflow opening 21, the use comfort of the ventilation device can be increased, since the air flow L is directed in a less laminar manner.

Fig. 2 shows the cockpit of a vehicle with a ventilation device whose outflow opening 21 directs an air flow L through a supply air slot 220 into the passenger compartment Z of the vehicle. The outflow opening 21 is hidden behind the two covering elements 22, 22' so that the outflow opening 21 is not visible from the passenger cabin Z. The air supply slit 220 extends across the width of the cabin along the dashboard of the vehicle. The air supply gap 220 is arranged between the two cover members 22, 22' spaced apart from one another. The trim strip 223 is provided for redirecting and/or shaping the air flow L. Since the outflow opening 21 is concealed behind the covering members 22, 22' and the trim strip 223, a greater degree of freedom is obtained in designing the cabin. In particular, large outflow openings to persons and/or slats which interfere with the space in terms of appearance are not required.

Fig. 3 shows an exemplary embodiment of a ventilation device in a vehicle, the control electronics 10 of which are coupled to a seat adjusting part V of a vehicle seat S of the vehicle. The air flow L flows into the passenger compartment Z from an air supply gap 220 in the dashboard between the two cover elements 22, 22'. In the upright orientation of the vehicle seat S, the air flow L is directed toward the head of the occupant P seated on the car seat S. In the lying position of the vehicle seat S, the air flow L continues to be directed towards the head of the occupant P. The angle of the air flow L has thus been reversed when the vehicle seat S is adjusted from the upright position into the lying position. This can be achieved, for example, by the adjusting device 1 lifting the upper covering member 22 of the two covering members 22, 22'. In the illustrated embodiment, two cover members 22 'are arranged one above the other, wherein one of the cover members 22 forms the upper side of the dashboard on the side of the vehicle roof and the other cover member 22' of the two cover members delimits the dashboard on the side of the vehicle floor.

This arrangement can also be seen in fig. 4, which shows the hatched seam of the dashboard. In fig. 4, the upper covering member 22 covers the interior space structural component I in the direction of the vehicle roof, while the lower covering member 22' covers the interior space structural component I in the direction of the vehicle floor. The outflow opening 21 is arranged on the interior space structure component I. The outflow port is designed for the air flow L to flow through the blowing gap 220 between the cover members 22, 22'. The contour of the cover element 22, 22' on the air supply gap 220 is funnel-shaped. The outflow port 21 is hidden from the passenger compartment Z by the cover members 22, 22'.

Fig. 5A and 5B show, in perspective and sectional views, respectively, an outflow opening 21, which is designed for directing an air flow L onto opposite surfaces of a cover member 22, 22'. In particular, the surfaces are closely spaced from each other so that the air stream L flows along both surfaces. Because the surface along which the air flow L is caused to flow is configured in a funnel shape, a first component L1 of the air flow flowing along the surface of the upper covering member 22 is redirected upwards, while a second component L2 of the air flow flowing along the surface of the lower covering member 22' is redirected downwards. The third component L3 of the air flow that does not flow along either of the surfaces is not redirected by the cover plates 22, 22'. Due to the funnel-shaped design of the supply air gap 220, in particular due to the funnel-shaped surface of the cover elements 22, 22' on the supply air gap 220, the air flow L is thus widened. This means that the cross section of the air flow L proceeding from the outflow opening 21 is smaller than the cross section of the air flow L after the air flow L has passed around the cover elements 22, 22'. The air flow L can thus be guided and/or deflected and/or widened by the dashboard.

The series of figures 6A to 6E and 7A to 7D illustrate how the air flow L can be guided and broadened by the covering member 22, and in particular how the degree of turbulence can be controlled. Fig. 6A shows the outflow opening 21, from which the air flow L flows past the cover element 22. For example, the air flow L may flow into the passenger cabin Z. The angle W of the air flow L can be adjusted by the nozzle plate 210 of the outflow opening 21. An adjusting device 1 may be provided for adjusting the nozzle plate 210. In principle, the adjusting device 1 for adjusting the angle W of the air flow L can also adjust the outflow opening 21 in different ways. In particular, the adjusting device 1 can be set up for pivoting the outflow opening 21 relative to the cover member 22 in order to adjust the angle W of the air flow L. The air flow L exits the outflow opening 21 through the nozzle plate 210. The nozzle plate 210 is supported so as to be pivotable relative to the cover member 22 about an axis arranged perpendicular to the direction of exit of the air flow L.

In fig. 6B, the air flow L is adjusted by 10 ° in the direction of the cover member 22, as compared with fig. 6A. In both cases the air flow L is laminar. There is no interaction between the air flow L and the cover member 22 because the air flow L is spaced apart from the cover member 22. In fig. 6C, the outflow port 21 flows at least one component of the air flow L onto the surface of the cover member 22. The angle W in fig. 6C is adjusted by 15 ° compared to fig. 6B. The component is slowed by interaction with the surface of the cover plate 22 relative to another component of the air flow L that does not flow onto the surface of the cover plate 22. Thereby swirling the two components relative to each other. Thus, the degree of turbulence in the air flow L will increase as the air flow L passes by the cover plate 22. The cover member 22 interacts with the air flow L over an angled section of the surface. The angled section is in particular of obtuse-angled design. The angled sections sink into the air flow L in sections along the cross-sectional area of the air flow L, so that the air flow L is partially slowed and/or blocked, thereby creating turbulence.

In fig. 6D, the air flow L is adjusted by 35 ° in the direction of the cover member 22, as compared with fig. 6A. The air flow L now encounters a flat section of the surface adjacent to the angled section of the surface. The air flow L flows along a flat section onto an angled section, where it is redirected and at least one component of the air flow L is slowed down. Thereafter, the air flow L flows along another flat section adjoining the angled section. The air flow L thus flows along the contour of the cover member 22. Further, the air flow L is swirled. The angle at which the air flow L flows into the passenger compartment Z is greater than the angle W at which the air flow L leaves the outflow opening 21. Thus, the cover member 22 is configured to redirect the air flow L.

In fig. 6E, the air flow L is further adjusted by 5 ° in the direction of the cover member 22, compared to fig. 6D. The air stream L flows in a laminar manner along the flat section, the angled section and the other flat section. The air flow L thus flows into the passenger cabin Z along an angle on the covering element 22 determined by the contour of the covering element 22. In particular, the angle at which the air flow L flows into the passenger cabin Z is greater than the angle W at which the air flow L leaves the outflow opening 21. The air flow L can flow in a laminar manner along the surface of the cover member 22 based on the coanda effect.

The precise illustration of the angle W of the air flow L is merely exemplary and is for illustration only. In principle, the features described in connection with the angles can be provided for any other angle and any other design of the cover member 22 and the outflow opening 21.

In the series of fig. 7A to 7D, the cover member 22 is pivotable with respect to the outflow port 21. Furthermore, the cover member 22 is movable relative to the outflow opening 21, so that the cover member 22 performs a rolling movement relative to the outflow opening 21. In principle, the cover member 22 can be movable or pivotable only relative to the outflow opening 21. Between fig. 7A to 7B, the cover member 22 is pivoted by an angle X relative to the outflow port 21 in the direction of the air flow L. The air flow L flows past the cover member 22 in a laminar manner. In fig. 7C, the cover member 22 sinks into the air flow L by pivoting the air flow L further in the direction of the air flow L than in fig. 7B and moving in the outflow direction of the air flow L from the outflow port 21. A component of the air flow L is slowed down on the cover member 22 such that the degree of turbulence in the air flow L increases. In fig. 7D, the cover member 22 is further adjusted in the direction of the air flow L. Thereby, the air flow L flows in a laminar manner along the surface of the cover member 22. In particular, the angle at which the air flow L flows into the passenger compartment Z is greater than the angle W at which the air flow L flows out of the outflow opening 21.

An alternative design of the cover member 22 is illustrated in the series of fig. 8A to 8C. The air flow L leaves the outflow opening 21 in a direction vector R in laminar flow and with a low degree of turbulence or in laminar flow. The air flow L bypasses the covering element 22 and flows into the passenger cabin Z. The contour of the cover member 22 includes an acute-angled section by which the air flow L flows along the direction vector R in fig. 8A. If the cover member 22 is adjusted in the direction of the air flow L such that the acutely angled section of the cover member 22 sinks into the air flow L, as shown in fig. 8B, the degree of turbulence of the air flow L bypassing the cover member 22 will increase. Furthermore, the air flow L becomes more dispersed. The air flow L is deflected beside the cover member 22 in a direction away from the cover member 22. A part of the air flow L can furthermore follow the flow on the side of the cover member 22 facing away from the outflow opening 21.

If the cover 22 is further adjusted in the direction of the air flow L so that the cover 22 blocks the air flow L, the air flow L is redirected along the surface of the cover 22. In the section at an acute angle, the air flow L escapes from the covering element 22 and flows into the passenger cabin Z at an angle W determined by the contour of the covering element 22 along which the air flow L flows. In particular, the angle W is different from the direction vector R. In particular, the air flow L does not flow over the acutely angled section onto the other flat section of the cover member 22, because the coanda effect is interrupted at the acutely angled section. In this embodiment, the cover member 22 is vertically movable. The cover member 22 moves from above, i.e., from the direction of the vehicle roof toward the direction of the air flow L. Thereby, the air flow L is redirected, for example, in the direction of the foot space of the vehicle. In principle, the cover element 22 can also be moved into the air flow L from below, so that the air flow L is redirected, for example, in the direction of the head section of the backrest E of the vehicle seat S.

Fig. 9A shows a cockpit of a vehicle in which two covering members 22, 22' for covering an interior space structural assembly I are arranged. The first covering element 22 here forms a covering of the interior space structure component I on the vehicle windshield C side. The second covering element 22' forms a covering of the interior space structural component I on the footwell side of the passenger cabin Z. The cover members 22, 22 'are spaced apart from each other along the longitudinal sides on which the control apparatus T of the vehicle is arranged, so that a first air blowing gap 220 is arranged between the cover members 22, 22'. The first outflow port 21 causes the air flow L to flow into the passenger compartment Z of the vehicle through the first outflow slit 220 in the direction of the occupant P of the vehicle.

The first cover member 22 is arranged in a pivotable manner about an axis a parallel to the first air blowing slit 220. The first air blowing slits 220 are released in the first adjustment position of the first cover member 22 to cause the air flow L to flow out from the first outflow port 21. In the second adjusted position of the first cover member 22, the first cover member 22 pivots about the axis a relative to the first adjusted position. The first air blowing slit 220 can be closed by the pivoting of the first cover member 22. In fig. 9B, a second air blowing gap 220' between the first cover member 22 and the vehicle structure is illustrated, which is released by the pivoting of the first cover member 22 about the axis a. The second outlet 21 'allows the air flow L to flow through the second blowing gap 220' in the direction of the windshield C. In principle, the first outflow opening 21 can also pass the air flow L through the second blowing slot 220'. For this purpose, the first outflow opening 21 can also be adjusted in the direction of the second blowing slot 220'. However, in particular, a plurality of outlet openings may also be provided, which each allow an air flow L to flow into the passenger cabin Z or in the direction of the windshield C via one or more blowing slots.

Fig. 10A shows the cabin of a vehicle with two cover members 22, 22 ', between which cover members 22, 22' a blowing gap 220 can be released, similar to fig. 9A and 9B. The air blowing slit 220 can be released by the first cover member 22 moving in the vertical direction. In the first adjustment position in fig. 10A, the first cover member 22 is in contact with the second cover member 22', thereby closing the air blowing slit 220. In the second adjustment position in fig. 10B, the first cover member 22 is spaced apart from the second cover member 22 ', thereby freeing the air supply gap 220 between the first cover member 22 and the second cover member 22'. In principle, each of the two cover members 22, 22 ' can be displaced relative to the other cover member 22 ', 22 '. In particular, the size of the blowing gap 220 can be steplessly adjusted by adjusting the cover members 22, 22'. In one embodiment, the flow rate and/or volume of the air flow L can be adapted by the size of the supply air gap 220. The volume of the air flow L can be defined here by the amount of air which can flow into the passenger cabin Z per unit time.

In fig. 11, the second cover member 22' is formed of an elastic. The second cover member 22 'is arranged on the winding element 221, onto which the second cover member 22' can be wound. To vary the air supply gap between the first cover member 22 and the second cover member 22', the winding element 221 can be adjusted in the direction of the first cover member 22, which is indicated by the double arrow in fig. 11. For example, wound elements

The second cover member 22' may be unrolled so as to close the outflow opening 220, as illustrated in fig. 12A. The winding element 221 may wind up the second cover member 22' so as to open the blowing slit 220, as illustrated in fig. 12C. Furthermore, the air flow L can be redirected and shaped by the distance of the winding element 221 from the air flow L. In fig. 12B, the air flow L flows, for example, along the section of the second cover member 22' wound on the winding element 221. The profile of this section is determined by the shape of the wrapping element 221. Here, the air flow L flows into the passenger compartment Z at a different angle from when the air flow L exits the outflow port 21. Of course, the degree of turbulence of the air flow L can also be controlled in principle by the adjusted positioning of the winding element 221.

Fig. 13A shows a second cover member 22' made of an elastomer in the cabin of the vehicle, which is arranged on the adjusting element 222, similar to fig. 9A and 9B. By adjusting the adjusting element 222, the section of the second cover member 22' can be adjusted in a direction parallel to the first cover member 22, so that the size of the air supply gap 220 remains unchanged during adjustment. In principle, the adjustment element 222 may be a winding element 221 onto which the second cover member 22' can be wound. The second cover member 22' may in principle be made of any elastic material, for example an elastomer. For example, the second cover member 22' may be elastically deformed to deflect the air flow L. For example, the adjustment element 222 is adapted to deform the second cover member 22'. Likewise, at least one actuator may be provided for the second cover member 22 'to deform the second cover member 22'.

With the adjustment of the adjusting element 222, the contour of the surface of the second covering component 22' can be adjusted, along which the air flow L can flow into the passenger cabin Z. In fig. 13A, the distance between the adjusting element 222 and the outflow opening 21 is smaller than in fig. 13B. The surface of the second cover member 22' has a convex shape on the adjustment element 222, which shape is set by the adjustment element 222. If the adjusting element 222 is arranged at a smaller distance from the outflow opening 21, the air flow L is deflected more strongly along the surface, in particular the convex surface, of the second cover member 22'. The rim of the second cover member 22' is fixed at the level of the outflow opening 21. If the adjusting element 222 is arranged at a greater distance from the outflow opening 21, the adjusting element 222 forms a bulge in the direction of the passenger cabin on the second covering component 22 ', so that the air flow L exiting from the outflow opening 21 flows along a flat section of the second covering component 22' to the adjusting element 222. The air flow L is deflected less strongly on the adjusting element 222 on the convex section of the second cover member 22', since the air flow L first flows along a flat section before flowing along the convex section. In this way, the deflection strength of the air flow L may be controllable by means of the adjusting element 222. The adjustment element 222 can thus change the angle between the second cover member 22' and the outflow opening 21.

Fig. 14A and 14B show an embodiment of a vehicle cabin with two cover members 22, 22' between which an air supply gap 220 is arranged. On the second cover member 22' a pointing element 223 is arranged, which can be adjusted for redirecting and/or shaping the air flow L. The directional element 223 is convexly shaped with respect to the air flow L. The pointing element 223 may extend along the entire length of the air supply slit 220. In fig. 14A, at least one section of the directional element 223 is arranged parallel to the direction vector R along which the air flow L leaves the outflow opening 21. The air flow L flows along the directional element 223 and is deflected in the direction of the vehicle foot well at a section of the directional element 223 that is curved in the direction of the vehicle foot well. In fig. 14B, the pointing element 223 is adjusted in the direction of the air flow L. The directional element 223 is arranged transversely to the air flow L. The direction vector R thus intersects the pointing element 223. The air flow L is thereby deflected in the direction of the vehicle roof. In principle, the pointing element 223 may be movable or pivotable with respect to the air flow.

In one embodiment, the pointing element 223 is made of a shape memory material, for example a shape memory plastic. For example, the pointing element 223 may change its shape between a first configuration and a second configuration depending on a parameter such as temperature. For example, in the first configuration the directional element 223 may redirect the air flow L in a direction towards the roof of the vehicle, whereas in the second configuration the directional element 223 may redirect the air flow L in a direction towards the floor of the vehicle. In general, the use of actuators or electronic components may not be required.
