Description

[0001] The invention relates to an air outlet device for a motor vehicle with an air guide element by which the intensity and / or direction of an airflow passing through the air guide element can be adjusted, according to claim 1. Furthermore, the invention relates to an interior trim panel for a motor vehicle with a trim element in which at least one air outlet device is arranged, according to claim 8. Finally, the invention relates to a method for operating an air outlet device according to claim 10.

[0002] Motor vehicles typically have a ventilation or air conditioning system that uses ducts to regulate the temperature of the vehicle's interior. These ducts distribute conditioned air throughout the vehicle. In modern vehicles, the airflow enters the interior through so-called "fresh air grills." These grills are openings in the interior trim, where horizontally and vertically arranged louvers essentially form a grid structure (or grille) that directs the airflow in various directions. The orientation of the louvers allows for three-dimensional airflow control. The combination of vertical and horizontal louvers and their respective orientations determine the direction of airflow. For example, if the horizontal louvers are oriented downwards, the airflow is directed downwards.If the vertical louvers are oriented to the left, the air flows to the left. If both the horizontal and vertical louvers are simultaneously positioned downwards and to the left, the air flows downwards and to the left. To direct the louvers in the desired direction, a user typically moves or shifts them manually. If the louvers are to be moved by an actuator, one actuator is provided for each of the vertical and horizontal louvers. A further actuator is required for airflow regulation.

[0003] Even in modern cockpits or dashboards, which often do without physical controls, the louvers usually have to be operated manually. Such operation is distracting, even if settings are transferred via the vehicle's key. However, settings cannot be transferred for manual controls.

[0004] DE 10 2022 000 946 A1 discloses an air outlet for a vehicle, comprising a ventilation duct element and an air guide element, which is pivotably mounted in the ventilation duct element in at least one direction about at least one pivot point, wherein a control device is provided by which at least one basic setting of the air guide element relative to the ventilation duct can be detected and, depending on at least one defined state, the air guide element can be moved into the basic position by means of at least one displacement element, by which the air guide element can be displaced about the at least one pivot point relative to the ventilation duct element.

[0005] If the louvers can be adjusted with actuators, the cost of the air outlet device is particularly high due to the number of actuators required. Furthermore, actuators require energy, have their own weight, and are prone to defects. Louvers are mechanical parts that require the movement of hinges, levers, knobs, dials, etc. Mechanical parts can wear out and fail, potentially leading to quality issues. Another problem with louvers is that the air outlet is always open, allowing dust to collect and accumulate in the opening. This can increase friction and / or cause a significant amount of dust to enter the vehicle interior during operation.

[0006] The object of the present invention is to provide an air outlet device for a motor vehicle, an interior trim for a motor vehicle and a method for operating an air outlet device, which enables particularly advantageous simple, in particular automated, operation, with at the same time particularly low wear of mechanical components and in addition costs and / or dust entry into the vehicle interior can be particularly low.

[0007] This problem is solved according to the invention by the subject matter of the independent claims. Advantageous embodiments and further developments of the invention are the subject matter of the dependent claims, the description, and the drawings.

[0008] A first aspect of the invention relates to an air outlet device for a motor vehicle, which is particularly designed as a passenger car and / or truck. The air outlet device according to the invention comprises an air guide element by which the intensity and / or direction of an airflow passing through the air guide element can be adjusted. In order to specify or adjust the intensity and / or direction of the airflow, the air guide element can be transformed from a basic state in which the air guide element is closed to the airflow, by deformation, into a conducting state that adjusts or specifies the airflow.

[0009] The airflow is generated or directed, for example, by means of a duct element from a blower to the air outlet device, through which air from the duct element can enter the vehicle interior. The motor vehicle is specifically designed as a passenger car and / or truck.

[0010] To guide the airflow particularly effectively, the air guide element is formed from a plate, which is planar in its initial state, and has an outer and an inner region. These regions are connected by a segmented structure (similar to a spiral spring), which is reversibly deformable. Furthermore, the air outlet device has at least one switchable magnetic element, which is arranged upstream of the air guide element at a distance from an inner surface or the side facing the flow direction. The magnetic field of the at least one switchable magnetic element (generated in particular by switching) attracts the inner region, thereby generating the guiding state by deforming the structure.

[0011] The magnetic element is, for example, a coil, through which a magnetic field can be generated by an electric current. The direction or orientation of the magnetic field can be determined by the direction of the current flow. If the magnetic element is switched in such a way that a magnetic field is created, this attracts the inner area, which is, for example, magnetically formed or equipped with a magnet. The attraction of the inner area towards the magnetic element opens the cut, deformable structure, creating a directional opening so that the air outlet device is passable for the airflow, as this establishes the flow state.

[0012] In other words, the air guide element forms a nozzle that is closed when no magnetic field is present. Air can flow out of the nozzle when it is deformed, with air gaps opening as a result of this deformation. The orientation of the nozzle, and thus the intensity and / or direction of the airflow, is continuously adjustable between the neutral state and a fully open state, particularly depending on the strength of the magnet.

[0013] The nozzle, or air guide element, is essentially a flat spring. The spring geometry (spiral or meandering, etc.) is created by laser cutting into a plate or decorative strip (stainless steel, aluminum, wood, plastic, or metal substrate). The resulting geometry is particularly flexible, especially more so than the base material alone. This creates a compliant mechanism, as the mechanism is manufactured as a single piece without hinges.

[0014] The nozzle's deformation is achieved magnetically. Control of the nozzle is thus based on a reversible deformation of the air guide element and requires no moving parts or actuators, but only at least one magnetic element. In particular, several magnetic elements are arranged so that the interior can be tilted in the desired direction. In this way, all main directions, as well as the on and off positions, can be achieved by the air outlet device. The nozzle can therefore be adjusted in all directions, and in its default state, the air guide element of the air outlet device is completely flat towards the vehicle interior, allowing it to be particularly advantageously integrated into a trim strip, for example.

[0015] Another advantage is that the deformability of the air guide element allows for a compliant or flexible mechanism, thus requiring very few components. This results in particularly low manufacturing costs, as the air guide element is essentially produced from the sheet in which the cut structure is created using a laser cutter, eliminating the need for lamellae and joints. Furthermore, the ground state can be reached simply by switching off the magnet, meaning no additional energy is consumed for the transition to the ground state.

[0016] In an advantageous embodiment of the invention, the cut structure is spirally and / or meanderingly shaped, and / or a transition zone to the outer area, i.e., the area where the cut structure transitions into the outer area, is annular or circular, and / or the inner area is annular or circular. In other words, the connection between an inner plate of the nozzle and the outer part of the nozzle is formed by spiral spring arms. Thus, the cut structure is essentially designed as a flat spring, making it particularly flexible and deformable. Furthermore, the structure as a whole can be essentially annular. Depending on the width or fineness of the cuts, the basic state is either dense for the airflow, or the airflow can only pass through the air guide element marginally within the manufacturing tolerances.Additionally or alternatively, other cutouts are possible, so that the element remains flexible and, when converted into a ducted state, allows for free space for the outflowing air. This offers the advantage that the air guide element can be particularly well-shaped or adapted to an interior.

[0017] In a further advantageous embodiment of the invention, at least the inner region of the plate is magnetic and / or a magnetic ring is attached to the inner region. In other words, the plate is made of a magnetic or magnetizable material, such as a metal, or a ring, particularly a metallic ring or magnetic ring, is arranged on the inner region, so that the inner region can be attracted or repelled by the at least one switchable magnetic element, in particular to enable deformation of the cut structure and thus achieve the conductivity state. The ring and / or the inner region thus each form a permanent magnet. In this way, the conductivity state can be achieved particularly advantageously.

[0018] In a further advantageous embodiment of the invention, several magnetic elements are arranged at intervals from one another in a predetermined position relative to the interior and thus, optionally, also to the ring, thereby allowing the direction of the airflow to be predetermined. In other words, several switchable magnets are arranged such that each is assigned to a sub-area of ​​the interior, enabling each sub-area to be deflected, and in particular attracted, independently. For example, four magnetic elements are provided: one for an upward airflow, one for a downward airflow, one for a flow to the left, and one for a flow to the right, thus representing the four main directions. Advantageously, eight magnetic elements are arranged accordingly, so that, in addition to the main directions, intermediate directions, such as a downward oblique flow to the left, can also be achieved.The use of multiple magnetic elements offers the advantage that the direction of the airflow can be adjusted particularly effectively.

[0019] In a further advantageous embodiment of the invention, two magnetic elements, in particular magnetic elements opposite each other in the inner region, can be switched together in pairs. In other words, the coils can be energized in pairs such that one coil attracts the permanent magnet, i.e., the inner region or the ring arranged therein, and, for example, on the opposite side, the coil repels the permanent magnet and thus the inner region. This ensures that the magnetic field of the coils does not attract the permanent magnet so strongly that the nozzle or plate is completely open, and thus, in particular, the intensity of the airflow can be regulated. This offers the advantage that the intensity can be controlled in an advantageous manner.

[0020] In a further advantageous embodiment of the invention, the magnetic element comprises a solenoid whose core is arranged or fixed to the structure and / or the interior. In other words, an actuator with a sliding ferromagnetic piston inside a coil is provided. Without current supply, the piston or the core is located outside the coil over a portion of its length; when current is supplied, the piston is drawn into the coil, thereby enabling the conduction state to be achieved due to the attachment of the core to the air guide element or its structure and / or interior. This offers the advantage that the conduction state can be adjusted with particular precision.

[0021] In an advantageous embodiment of the invention, a retaining element is provided for the air guide element and / or a further retaining element is provided for the at least one magnetic element. In other words, the flat plate is arranged on a retaining element, which may in particular have a channel wall having the shape of the transition area to the outside, and the air guide element is mounted on the retaining element such that the opening is in alignment with the cut structure. Additionally or alternatively, a further retaining element is provided for the at least one magnetic field, for example in the form of a rod, which may be curved, and at the end of which a winding for a coil may be formed, or the magnetic element may be wound around the end of the rod to form the coil. Advantageously, the two retaining elements are formed as one retaining element and, moreover, in particular, as a single piece.

[0022] In a further advantageous embodiment of the invention, a stop element, which prevents movement of the air guide element in the direction of flow, is arranged on the inner surface. Additionally or alternatively, a limiting element is provided, which limits movement of the air guide element against the direction of flow, wherein the limiting element can, in particular, be formed, for example, by the further retaining element for the at least one magnetic element. In other words, a plate, particularly a star-shaped one, i.e., a ring, which is mounted on the inner surface with radially outward-extending rods that reach into the outer surface, is provided as a stop element, so that the air guide element cannot be opened outwards unintentionally, thereby preventing, for example, a user from getting caught on it.In the limiting element, the coil's mounting essentially prevents the spring from deforming. The magnetic field then pulls the ring-shaped magnet all the way to the stop against the mounting element, eliminating the need for precise control of the magnetic field. This stop ensures the line is in a fully open position. As a result, the air outlet device operates with exceptional reliability and minimal wear.

[0023] A second aspect of the invention relates to an interior trim panel for a motor vehicle, comprising a trim element, in particular a decorative strip, in which at least one air outlet device according to the first aspect of the invention is arranged, wherein an air guide element of the air outlet device is formed in or with the trim element (and in particular also integrally with it). In other words, the air guide element is a complete part of a decorative strip and / or is formed in it.

[0024] Advantageous embodiments and further developments, as well as advantages of the first aspect of the invention, are to be regarded as advantageous embodiments and further developments, as well as advantages of the second aspect of the invention, and vice versa.

[0025] In an advantageous embodiment of the invention, several air guide elements of multiple air outlet devices are formed in the trim element, and these air guide elements are arranged in this trim element as a matrix, and thus particularly in columns and / or rows. In other words, individual nozzles form "pixels" in a decorative trim strip, so that the trim strip simultaneously serves as a fan, thereby saving parts, complexity, costs, and / or process or cycle times. At the same time, this offers the advantage that the vehicle has fewer components and / or a particularly aesthetic design. Furthermore, all nozzles can be adjusted in one direction or selectively, for example, the left half to the left, the right half to the right, or the like. Thus, a particularly individualized adjustment is possible due to the arrangement of the air guide elements. In addition, a pulsating effect, such as a wave, can be generated.This makes the interior lining particularly advantageous for the user.

[0026] A third aspect of the invention relates to a method for operating an air outlet device for a motor vehicle with an air guide element, by which an intensity and / or a direction of an airflow passing through the air guide element is adjusted, for which purpose the air guide element is transformed from a basic state in which the air guide element is closed to the airflow by deformation or deformation into a conducting state which adjusts the airflow.

[0027] To adjust the airflow particularly advantageously, the air guide element is formed from a planar plate having an outer and an inner area, which are connected to each other by a cut and deformable structure, and at least one switchable magnetic element, which is arranged at a distance from an inner side of the air guide element, is switched, so that the inner area is attracted by its magnetic field, which can be generated or provided in particular by the switching, whereby the conduction state is created by deformation of the structure.

[0028] Advantageous embodiments and further developments, as well as advantages of the first and second aspects of the invention, are to be regarded as advantageous embodiments and further developments, as well as advantages of the third aspect of the invention, and vice versa.

[0029] In an advantageous embodiment of the invention, the intensity and / or direction of the airflow are predetermined via a control element, in particular a touch-sensitive screen or touchscreen, by means of voice control and / or by a setting stored in a key. In other words, the air guide element or air outlet device can be controlled via a touchscreen using voice commands, for example, via a microphone and suitable speech recognition. Additionally or alternatively, a car key for a specific user, or their preferred settings, can be stored in a customized model. These settings can also include the air outlet device, so that the desired settings can be applied when the vehicle is started. This offers the advantage that the method can be initiated particularly advantageously by a user.

[0030] A fourth aspect of the invention relates to a motor vehicle which comprises an air outlet device according to the first aspect of the invention and / or an interior lining according to the second aspect of the invention and / or which is further configured to carry out a method according to the third aspect of the invention.

[0031] Advantageous embodiments and further developments, as well as advantages of the first, second and third aspects, are to be regarded as advantageous embodiments and further developments, as well as advantages of the fourth aspect of the invention, and vice versa.

[0032] Further features of the invention will become apparent from the claims, the figures, and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown in the figures alone, are not only usable in the combinations specified, but also in other combinations or on their own.

[0033] The invention will now be explained in more detail with reference to a preferred embodiment and the drawings. The drawings show: Fig. 1 a schematic, perspective exploded view of an air discharge device with an air guide element; Fig. 2 a schematic side view of the air outlet device; Fig. 3 a schematic top view in the direction of flow of the air outlet device; Fig. 4 a schematic top view against the direction of flow of the air outlet device; Fig. 5 a cutaway side view of the air outlet device in a duct state; Fig. 6 a cutaway side view of the air outlet device in the conduction state with magnetic field lines of two magnetic elements; Fig. 7 a cutaway side view of the air outlet device with a first embodiment of a retaining element for the magnetic elements; Fig. 8 a cutaway side view of the air outlet device with a second embodiment of the retaining element of the magnetic elements; Fig. 9 a schematic perspective view of the air outlet device with the first embodiment of the retaining element; Fig. 10 a schematic perspective view of the air outlet device with the second embodiment of the retaining elements; Fig. 11 a schematic perspective view of an interior lining in the direction of flow comprising several air outlet devices; Fig. 12 a schematic perspective view of the inner lining against the direction of flow; and Fig. 13 a cutaway side view of a second embodiment of the air outlet device in a line state.

[0034] Fig. Figure 1 shows a schematic exploded view of an air outlet device 10 for a motor vehicle with an air guide element 12, by which the intensity and / or direction of an airflow 14 passing through the air guide element 12 can be adjusted, for which purpose the air guide element 12 is made of a Fig. The basic state shown in Figure 1, in which the air guide element 12 is closed to the airflow, can be transformed into a conduction state that regulates the airflow by deformation or deformation. One possible airflow 14, and thus conduction state, is shown in Figure 1. Fig. 4 and Fig. 5 shown.

[0035] The air guide element 12 is formed from a plate that is planar, at least in its basic state, and has an outer area 16 and an inner area 18, which are connected to each other by a cut structure 20 that is, in particular, reversibly deformable. Furthermore, at least one switchable magnetic element 22, and in the illustrated embodiment, eight magnetic elements 22, each formed by a coil, are arranged at a distance from an inner surface 24 of the air guide element 12, wherein the inner area 18 can be attracted by the respective magnetic field of the respective magnetic element 22, whereby the guide state can be generated by deformation of the structure 20, and thus a direction and / or intensity of the airflow 14 can be predetermined.

[0036] The cut structure 20 is specifically spiral or meander-shaped, and a transition area to the outer surface 16 is ring-shaped or circular, and the inner surface 18 is also circular. In other words, the air guide element 12 is designed as a flat spring. The spring geometry is created, for example, by laser cutting into a plate or decorative strip made of stainless steel, aluminum, wood, plastic, or metal. Due to the resulting geometry, it is particularly flexible, and a compliant mechanism is realized which can adjust the airflow 14 solely through deformation, without any moving parts. Thus, the inner surface 18 of the plate is magnetic or forms a permanent magnet. Additionally or alternatively, a magnetic ring 26 can be attached to the inner surface 18.

[0037] The magnetic elements 22 are spaced apart from each other and arranged in a predetermined position relative to the inner area 18, so that the latter can be moved accordingly to create the airflow 14. It is advantageous that two magnetic elements 22, in particular opposing magnetic elements 22, can be switched together in pairs.

[0038] Depending on the available space, any number of coils or magnetic elements 22 can be implemented. For example, one coil for each principal direction left, right, up, down, and the combined directions up right, up left, down right, down left.

[0039] By energizing the individual coils, the permanent magnet or the ring 26, which can be a ferromagnetic ring 26 and need not be a permanent magnet, is attracted by magnetic fields generated in the coil. More precise directions or intermediate stages are also possible if only two adjacent coils are energized simultaneously. In this case, coils are energized by a control unit, and the change from one position (ground state, line state) to another position can be implemented instantaneously and / or silently. Furthermore, two wires are provided in pairs for each coil or magnetic element 22, which are led to a power source, such as the control unit.

[0040] Furthermore, the Fig. 1 a holding element 28 for the air guide element 12 and a further holding element 30 for the at least one magnetic element 22 or the eight magnetic elements 22. In addition to the air discharge device 10, a method for operating the same is presented here, in which the airflow 14 is adjusted by switching the magnetic elements 22.

[0041] A particularly star-shaped plate, i.e. a ring with radially outward-extending rods, is provided as a stop element 40, which is mounted on the inside and the rods extend, for example, into the outside, so that the air guide element cannot be opened unintentionally to the outside.

[0042] The intensity and / or direction of the airflow 14 can be adjusted via a control element, in particular a touch-sensitive screen, by means of voice control and / or by means of a setting stored in a vehicle key. Fig. Figure 2 shows the air outlet device 10 in a side view in its basic state.

[0043] Fig. Figure 3 shows the air outlet device 10 viewed in the direction of flow in a top view, whereby the spacing of the individual veins in the cut structure 20, particularly in the upper area, indicates that the air guide element 12 is in an open state or in a conducting state.

[0044] Fig. Figure 4 shows the corresponding guiding state in a top view against the direction of flow, showing in which direction the airflow 14 flows from the air guide element 12 into the vehicle interior.

[0045] Fig. Figure 5 shows the same air guidance state in a cutaway side view of the air outlet device 10, showing how the airflow 14 passes through it and thereby determines the direction and intensity or quantity.

[0046] Fig. Figure 6 also shows a cutaway side view of the air outlet device 10, showing the corresponding permanent magnet fields of the ring 26 and the corresponding switched magnetic fields or magnetic field lines of two magnetic elements 22, while the other six magnetic elements 22 are not switched or are switched off. The magnetic field of the permanent magnet or ring 26 is always oriented in the same way. The individual coils or magnetic elements 22 are energized such that the direction of the current causes the generated magnetic field to both repel and attract the permanent magnet. Thus, the coils are energized in pairs, and the attraction on one side and repulsion on the other ensures that the combined magnetic field does not attract the ring 26 so strongly that the plate of the air guide element 12 is pulled so tightly that the nozzle opens completely.For example, the intensity of the airflow 14 can be controlled.

[0047] The Fig. 8 and Fig. Figure 9 shows a different embodiment of the further retaining element 30, which additionally fulfills a function as a limiting element, so that it limits the deformation of the spring or the air guide element 12, so that the magnetic field pulls the ring 26 to the stop, so that control of the magnetic field can be omitted, since a maximum opening can be specified.

[0048] The Fig. 9 and Fig. Figure 10 shows the embodiments of the further retaining element 30 of the Fig. 7 and Fig. 8 each in a schematic perspective view.

[0049] Furthermore, it is possible to form an inner lining 32 from at least one of the air outlet devices 10, wherein several air guide elements 12, as in Fig. 11 shown in a schematic perspective view, can be arranged side by side. Fig. Figure 12 shows, as it were, the view from the interior of the air guide elements 12, which together form a decorative strip or a strip element 34.

[0050] Fig. Figure 13 shows a sectional side view of the air outlet device 10 in a conduction state, wherein the respective magnetic element 22 has a solenoid 36 whose core 38 is fixed to the air guide element 12, particularly at a specific position in the inner region 18. The movable core 38 of the solenoid 36 can be formed integrally with the deformable air guide element 12 or as a separate part. The latter can be glued, welded, and / or soldered on. A base plate of the core 38, which is attached to the air guide element 12, can be larger than the structure and / or project beyond its cuts, thus forming a stop element or replacing the existing stop element 40.

[0051] The coil holder is in Fig.13 is hollow, allowing the core 38 cavity to move. The magnetic field attracts the core 38 between it and the air guide element 12, causing deformation of the structure 20 and thus enabling the conduction state.

[0052] The design of the strip element 34 provides a component-free solution for ventilating a vehicle interior, which can also be designed to be particularly stylish, since, for example, in its basic state, the individual air guide elements 12 have a particularly smooth surface without protrusions for other outlet openings. Furthermore, the possible matrix arrangement of the air guide elements 12 allows for the creation of various effects, such as a pulsating effect analogous to a wave. At the same time, the air outlet device 10 is dust-protected in its basic state because it is sealed. The air outlet device 10, the interior trim 32, and the method described here constitute an actuator-free compliant air nozzle with an electromagnetic opening.
