Description

The invention relates to an air vent for a vehicle, in particular for a motor vehicle, according to the preamble of patent claim 1.

Such an air vent for a vehicle, in particular for a motor vehicle, for example, is already the DE 10 2010 036 691 B4 to be known as known. The air vent is also commonly referred to as a vent or air nozzle because the vent is used to supply air to the interior of the vehicle. The air is conveyed, for example, by means of a blower and thereby conveyed through the air vent, so that the air can flow through the air vent. The air flowing out of the air vent flows, in particular directly into the interior, whereby the interior is vented.

The air vent has at least one housing which has at least one channel through which air can flow. The air is supplied to the interior of the vehicle via the duct. The air vent further comprises at least one relative to the housing movable air guide for guiding the air. The air guide element is for example at least indirectly arranged or held on the housing and can be pivoted relative to the housing. In particular, it can be provided that the air-guiding element is arranged at least partially, in particular at least predominantly, in the housing. By means of the air guide element, for example, the air can be selectively directed or deflected so that the air flowing out of the air outlet flows, for example, specifically into a partial region of the interior.

The air vent further comprises at least one light-emitting element fixed at least indirectly to the housing, by means of which light can be provided for at least partial illumination of the air-guiding element. In other words, by means of the luminous element, in particular by means of the light provided by the luminous element, at least a portion of the air-guiding element can be illuminated.

Object of the present invention is to develop an air vent of the type mentioned in such a way that a particularly advantageous actuation of the air guide can be realized.

This object is achieved by an air vent with the features of claim 1. Advantageous embodiments with expedient developments of the invention are specified in the remaining claims.

In order to further develop an air vent of the kind specified in the preamble of patent claim 1 such that a particularly advantageous and in particular simple or pleasant actuation of the air guide element can be realized, it is provided according to the invention that at least one subregion of the air guide element that is movable relative to the light element can be pivoted is designed as a light guide, in which the light provided by the light emitting element can be coupled. The light guide is thus translucent. The coupling of light into the light guide means that at least part of the light provided is radiated into the light guide. The light irradiated or coupled into the light guide can, for example, propagate or distribute in the light guide and is guided and / or distributed, for example, by means of the light guide, so that the light guide itself is illuminated.

Furthermore, the air vent comprises a bearing which is held at least indirectly on the housing and which has an outer peripheral side and at least partially spherical first bearing surface. In this case, the air-guiding element is mounted pivotably on the first bearing surface and thus on the bearing, by means of a bearing element formed separately from the bearing and separately from the air-guiding element. The bearing element is connected to the air guide, so that the air guide is mounted on the bearing element on the first bearing surface and thus on the bearing. In particular, the air guide element is mitbewegbar with the bearing element, so that the air guide element can be pivoted together with the bearing element relative to the bearing on the first bearing surface. In this case, the bearing element has a corresponding to the first bearing surface second bearing surface, via which the bearing element is pivotally mounted on the first bearing surface and thus on the bearing. The second bearing surface is, for example, spherically formed at least in a partial region, so that, for example, a pan or ball socket is formed by the second bearing surface, in which, for example, a head formed by the first bearing surface, in particular ball head, is at least partially accommodated.

Due to the fact that the air guiding element or the light guide is movable relative to the lighting element, an impairment of the pivotability of the air guiding element caused by the lighting element can be avoided, so that the air guiding element can be operated particularly advantageously, in particular particularly pleasantly and easily. Under such an actuation of the air guide element, a pivoting of the air guide element relative to the housing and relative to the bearing to understand. The light-emitting element is an integrated into the air vent illuminant, which there is no, caused by the bulb restrictions in the function and in the operation of the example designed as a ball nozzle air guide. In addition, it is possible, in particular through the use of separately formed from the bearing and separately from the air guide element bearing element, exactly tune and ensure a precise and constant operating force and feel with high perceived value throughout the range of motion of the bearing or air guide.

The air vent according to the invention can also be realized in a particularly simple manner, since the luminous element functioning as a luminous means no longer has to be arranged to be movable, but the luminous element can be arranged in a stationary manner relative to the housing. The guidance of the light from the luminous element to the air-guiding element, in particular to the optical waveguide, takes place for example via an optical coupling between the luminous element and the optical waveguide, so that the light provided by the luminous element is coupled into the optical waveguide. In this way, the light can be guided, for example, by means of itself in their relative spatial configuration during adjustment or pivoting of the air guide non-changing Lichtleitpfade of the light emitting element to the light guide.

Further advantages, features and details of the invention will become apparent from the following description of a preferred embodiment and from the drawing. The features and feature combinations mentioned above in the description as well as the features and feature combinations mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or in isolation, without the scope of To leave invention.

1 shows in a schematic longitudinal sectional view with a whole 10 designated Luftausströmer for a vehicle, which is designed for example as a motor vehicle, especially passenger cars. The air vent 10 is also referred to as an air nozzle, wherein the air vent 10 in the present case - as will be explained in more detail below - is designed as a ball nozzle. The air vent 10 includes a housing 12 which has an air intake 14 having. About the air intake 14 is the air vent 10 For example, connectable to an air supply of the vehicle. The vehicle includes, for example, an air conditioning device, which has a fan, by means of which air can be conveyed. For example, the air can be conveyed by means of the blower through at least a first duct of an air duct, wherein the air flowing through the first duct to the air vent 10 for example via the air inlet 14 can be supplied.

The housing 12 also has an air outlet 16 over which the over the air intake 14 in the case 12 incoming air from the housing 12 can flow out. Furthermore, the housing has 12 a traversed by the air, the second channel 18 on which the air from the first channel through the air inlet 14 can be supplied. This means that the channel 18 over the air intake 14 is fluidly connected to the aforementioned first channel. The channel 18 thus has the air intake 14 and the air outlet 16 on, so that's the channel 18 air flowing through the air outlet 16 from the channel 18 out and into the interior of the vehicle can flow. This allows the interior of the channel 18 or the air vent 10 be supplied by flowing air, whereby the interior can be ventilated.

The air vent 10 further comprises at least one relative to the housing 12 movable, in particular pivotable, air guide 20 to conduct the channel 18 flowing through and out of the canal 18 off and in the interior of incoming air. The outer circumference is the air guide 20 at least partially spherical or formed as a sphere or spherical segment, so that the air vent 10 is designed as a ball nozzle. The air guide 20 For example, a plurality of the channel 18 air flowing around slats 22 on, by means of which the air can be guided or directed or deflected.

Furthermore, the air vent comprises 10 at least one at least indirectly on the housing 12 fixed luminous element 24 , by means of which light for at least partial illumination of the air guiding element 20 is available. This means that the lighting element 24 Can provide light, by means of which at least a portion of the air guide element 20 can be illuminated. For this purpose, the luminous element comprises 24 at least one light source 26 which at least indirectly to the housing 12 is fixed. The light source 26 is designed, for example, as an LED and can provide said light, in particular radiate it. Furthermore, the luminous element comprises 24 at least a first light guide 28 which at least indirectly to the housing 12 is fixed. Because the light element 24 and thus the light source 26 and the light guide 28 at least indirectly to the housing 12 are fixed, are the lighting element 24 and thus the light source 26 and the light guide 28 with respect to the housing 12 fixed or stationary.

The light guide 28 For example, it is translucent and thus light-conducting with the light source 26 connected to that at least part of the light source 26 provided light in the light guide 28 coupled, that is radiated. That in the light guide 28 coupled or irradiated light can be in the light guide 28 spread or distribute and is by means of the light guide 28 led or led. In this case, the light guide 28 or the lighting element 24 a total decoupling area 30 on, over which the lighting element 24 , in particular the light guide 28 that from the light source 26 provided light provides or provides. This means that by means of the light guide 28 at least part of the light source 26 provided light from the light source 26 to the decoupling area 30 guided and then over the Auskoppelbereich 30 provided, that is broadcast.

Now to a particularly advantageous and particularly uniform and thus high-quality operation of the air guide 20 to realize is at least a subarea 32 of the air guide element 20 as a light guide 34 formed, wherein the air guide element 20 and thus the light guide 34 relative to the luminous element 24 movable, in particular pivotable and / or rotatable, are. The light guide 34 is thus a separate from the first light guide 28 trained and in addition to the light guide 28 provided, second light guide, which is translucent, while a coupling region 36 in which that via the decoupling region 30 provided light can be coupled. For example, the coupling-in area 36 at a short distance to the decoupling area 30 arranged. In contrast to the light guide 28 is the light guide 34 not relative to the housing 12 fixed, but relative to the housing 12 pivotable or rotatable. The light guide 34 is for example by a first component of the air guide 20 formed, with the slats 22 For example, by a separately formed from the first component and, for example, connected to the first component, second component are formed.

The over the decoupling area 30 provided and over the coupling area 36 in the light guide 34 coupled and thus irradiated light can, for example, in the light guide 34 distribute and will be using the light guide 34 , especially targeted, guided. As a result, the air guide element 20 at least in the area of the light guide 34 that is, at least in the subarea 32 by means of the luminous element 24 illuminated.

The air vent 10 further comprises at least indirectly on the housing 12 held, in particular movable and thereby for example pivotable and / or rotatable on the housing 12 kept, and especially good 2 recognizable bearing 38 , which for example by a on the housing 12 fixed wave 39 formed while at one end of the shaft 39 is provided. The wave 39 and thus the camp 38 are over struts 40 on the housing 12 held, with the support struts 40 for example, through the housing 12 are formed. As will be explained in more detail below, the air guide is 20 at the camp 38 under mediation of a bearing element 42 pivoted. The warehouse 38 is also very good 2 to 5 recognizable. This shows the camp 38 an outer peripheral side bearing surface 44 on, which is at least partially spherical, that is formed as a ball or spherical segment.

The bearing element 42 is separate from the warehouse 38 and separately from the air guide 20 formed and with the air guide 20 connected so that the bearing element 42 together with the air guide 20 relative to the housing 12 can be pivoted and / or rotated. In this case, the air guide element 20 under the mediation of the bearing element 42 at the storage area 44 and thus on the camp 38 pivoted. In this case, the bearing element 42 one with the first storage area 44 corresponding, inner peripheral side second bearing surface 46 which is also at least partially spherical or formed as a spherical or spherical segment. The bearing element 42 is about his second storage area 46 at the first storage area 44 and thus on the camp 38 pivoted. As part of the storage of the bearing element 42 at the camp 38 or at the storage area 44 is the storage area 46 at the storage area 44 supported. Due to the respective, spherical shape of the bearing surfaces 44 and 46 these have a spherical contour, whereby at least one pivoting of the air guide 20 relative to the housing 12 is possible. The air guide 20 and with this the bearing element 42 are for example - as in 4 by a double arrow 48 is illustrated - about a rotation axis 50 relative to the housing 12 rotatable as well as an in 3 illustrated pivot axis 52 relative to the housing 12 pivotable, in particular by at least substantially +/- 30 degrees. In this case, the pivot axis runs 52 perpendicular to the axis of rotation 50 ,

The wave 39 For example, is a journal through which the bearing 38 is formed. In particular, the wave 39 over that the bearing element 42 and the air guide 20 around the axis of rotation 50 relative to the housing 12 rotatable. In other words, become the air guide 20 and with this the bearing element 42 around the axis of rotation 50 relative to the housing 12 turned, the shaft rotates 39 with the bearing element 42 and with the air guide 20 around the axis of rotation 50 relative to the housing 12 With. It is for example with the shaft 39 a gear 54 rotatably connected, so the gear 54 around the axis of rotation 50 relative to the housing 12 with the wave 39 is rotatable. The gear 54 engages in a corresponding interlocking 56 one which by turning the gear 54 around the axis of rotation 50 around a perpendicular to the axis of rotation 50 extending pivot axis 58 is pivoted. This will be closing flaps 60 relative to the housing 12 pivoted. This means that the closing flaps 60 about the gearing 56 , the gear 54 , the wave 39 , the bearing element 42 and the air guide 20 is pivotable or adjustable, thereby for example, a flow-through of air flow cross-section of the channel 18 to be able to adjust. This allows the airflow passing through the air vent 10 flows, be regulated. A rotation of the air guide element 20 around the axis of rotation 50 opens or closes, depending on the direction of movement, the closing flaps 60 , In particular, it is conceivable that several closing flaps 60 are provided which operate, for example, according to the butterfly principle and in the direction of, for example, an axis of symmetry representing rotation axis 50 folded or towards the case 12 can be unfolded.

To the decoupling area 30 and the coupling area 36 to be able to arrange particularly close to each other and thereby an advantageous coupling of the light in the light guide 34 to realize, it is preferably provided that the decoupling 30 and the coupling area 36 are each formed spherical or spherical, wherein the coupling region 36 For example, at least partially in the decoupling region 30 is included.

The air guide 20 For example, is at least indirectly form-fitting with the bearing element 42 connected. For this purpose, for example, the light guide 34 or the subarea 32 first locking elements in the form of locking lugs 62 on, which with corresponding and for example as Rastaufnahmen 64 trained locking elements of the bearing element 42 interact positively and are locked with it. In other words, the light guide 34 with the bearing element 42 locked and thereby form-fitting with the bearing element 42 connected so that the air guide 20 over the subarea 32 positively with the bearing element 42 connected, in particular locked, is.

Furthermore, a separate from the air guide 20 trained and at least indirectly with the air guide 20 connected actuator in the form of a knob 66 provided, via which the spoiler element 20 pivotable, that is about the axis of rotation 50 rotatable and / or about the pivot axis 52 is pivotable. In 2 are for example through the light guide 34 formed luminous surfaces 68 of the air guide element 20 shown. The illuminated areas 68 allow indirect lighting of the air guide element 20 by means of the in the light guide 34 coupled light. As a result, for example, designed as a feeder knob 66 be backlit, for example, symbols, logos, etc. are feasible.

In 3 are for example through the light guide 34 formed further illuminated areas 70 recognizable, by which a direct lighting can be realized. 2 shows the air guide 20 in a neutral position. 3 shows the air guide 20 in a pivoting position, in which the air guiding element 20 is pivoted relative to the neutral position by an angle α. The angle α is for example 30 degrees, so that a total of a pivoting range of 60 degrees of the air guide 20 is provided.

The bearing element 42 For example, is formed as a 2-component plastic part and thus includes, for example, two different plastics, wherein by one of the plastics, the bearing surface 46 is formed. Thus, the storage area 46 For example, designed as a 2-component brake shoe, whereby a frictional force between the bearing surfaces 44 and 46 is adjustable as needed. The function of the storage area 46 or of the bearing element 42 is in particular, by the frictional force between the bearing surfaces 44 and 46 an at least substantially uniform and advantageous operating force and feel realize, especially when the air guide 20 over the knob 66 is pressed.

Out 4 is particularly clear that the trained example as a pin shaft 39 Positive locking elements in the form of pins 72 having, which in corresponding form-fitting elements in the form of recesses 74 of the bearing element 42 intervention. As a result, the wave acts 39 , in particular about the axis of rotation 50 , positive fit with the bearing element 42 together, so around the rotation axis 50 Torques between the shaft 39 and the bearing element 42 can be transmitted. Will thus be the bearing element 42 , in particular via the knob 66 to the rotation axis 50 turned, so takes the bearing element 42 the wave 39 due to the described positive interaction with, so that the shaft 39 and thus the gear 54 around the axis of rotation 50 to be turned around. This allows the closing flaps 60 over the knob 66 operated, that is moved or pivoted. The wave 39 Thus, the function of the torque transmission comes to control the closing flaps 60 to, so that the channel through which the air can flow 18 closed and can be opened.

Out 5 is particularly well recognizable that the camp 38 in particular 360 ° circumferentially in the entire pivoting range of the air guide element 20 encapsulated and, for example, in the knob 66 integrated and locked.
