Modular actuator, vehicle and method

Description

The invention relates to an actuating device, a vehicle and a method.

Actuating devices in vehicles are known from the prior art, in which a user can trigger a vehicle function by an actuation action. It is known to use proximity sensors in order to detect an approach of a user and, for example, to unlock a door lock of a vehicle door so that the user can easily open the vehicle door. Such proximity sensors are usually integrated into a door handle. Due to their geometry, door handles offer the advantage that they enable simple encapsulation of the sensor system in order to protect the sensor system from moisture and other environmental influences. However, if the sensor system is to be arranged, for example, on another vehicle part, such as a body part, then this is the case Encapsulation cannot easily be transferred to the body component due to a two-dimensional extension of the vehicle part.

It is an object of the present invention to at least partially remedy the above disadvantages known from the prior art. In particular, it is an object of the present invention to enable a sensor unit to be sealed for arrangement on a flat vehicle part of a vehicle, preferably outside a door handle of the vehicle, with improved manufacturing options and / or improved ease of use.

The above object is achieved by an actuating device with the features of claim 1, a vehicle with the features of claim 18, and a method with the features of claim 20. Further features and details of the invention emerge from the respective subclaims, the description and the drawings. Features and details that are described in connection with the actuating device according to the invention naturally also apply in connection with the vehicle according to the invention and / or the method according to the invention and in each case vice versa, so that with regard to the disclosure of the individual aspects of the invention, reference is always made to each other or can be.

According to a first aspect of the invention, an actuating device is provided for triggering a function of a vehicle by a user. The actuation device has an electronics unit with a sensor unit for detecting an actuation action by the user which is used to trigger the function of the vehicle. The electronics unit has an electronics outside, on which the operating action of the user can be detected by the sensor unit, and an electronics inside, which is opposite the electronics outside. Furthermore, the actuating device comprises a first envelope section for protecting the electronics inside and a second envelope section for protecting the electronics outside. The first and second envelope sections form, in particular to protect the electronics unit, a closed envelope, in particular around the electronics unit, for modular arrangement on a flat paneling element of the vehicle. The cladding element preferably forms part of a, preferably movable, vehicle part. The function of the vehicle can include, for example, unlocking a door lock, opening a vehicle door and / or switching on lighting and / or an electrical device. The vehicle part can comprise, for example, an external component or an internal component of the vehicle.

The electronics unit can in particular have a plurality of conductor tracks and / or electronic components, preferably in the form of semiconductor elements, in order to process electrical signals. Furthermore, the electronics unit can have an energy source for supplying energy to the sensor unit and / or an electrical connection for connection to a vehicle power supply. For example, it is conceivable that the sheath has a cable outlet through which cables can be guided from the electronics unit to an outside of the sheath. As a result, an electrical connection between the electronics unit and vehicle electronics and / or a vehicle power supply can be ensured. The electronics unit preferably has a flat extension. In particular, a long side of the electronics unit can be oriented vertically and / or horizontally on the vehicle part. The electronics inside and the electronics outside can each comprise, for example, one side of a printed circuit board of the electronics unit on which electrical components are arranged. In particular, the inside of the electronics is opposite the outside of the electronics with respect to the electronics unit. The inside of the electronics can also be oriented away from the cladding element. The sensor unit can preferably be oriented in such a way that the actuation action can be detected on the outside of the electronics, in particular when the user is on the outside of the electronics on the vehicle or in the vicinity of the vehicle. In particular, the actuation action can be detected on a cladding outer side of the cladding element. This can in particular mean that the actuation action can be detected on a surface of the cladding outside of the cladding element and / or that the actuation action can be detected at a distance from a surface of the cladding outside. It is conceivable that the sensor unit is designed, for example, for capacitive, inductive and / or optical detection of the actuation action and / or for detection of the actuation action by means of ultrasound. The sensor unit can preferably be used for motion detection, in particular for gesture detection, at a distance, in particular from 1 cm to 20 cm, preferably from 2 cm to 15 cm, particularly preferably from 5 cm to 10 cm, be designed for the actuating device.

The first and / or second envelope section can be fastened or fastenable directly or indirectly to the cladding element. The shell can preferably be arranged in relation to the cladding element in such a way that the second shell section faces the cladding element and the first shell section faces away from the cladding element. For example, the first envelope section can be formed by a housing shell which is fastened to the second envelope section with a sealing compound. However, it is also conceivable that the first shell section is applied to the electronics unit and the second shell section in at least partially liquid form. In particular, the shell can thus form a closed housing that can be attached to the cladding element in a modular manner. The second envelope section can terminate flush with the first envelope section or protrude beyond the first envelope section. It is also conceivable that the first envelope section protrudes beyond the second envelope section.

The cover, in particular the first and / or the second cover section, preferably has at least one fastening interface for fastening the cover to the cladding element. The fastening interface can be designed for screwing or for caulking the casing to the cladding element. For example, the fastening interface can comprise a bore through which a screw body and / or a projection for caulking can be inserted. However, it is also conceivable that the shell can be riveted, glued or otherwise fixed to the cladding element through the fastening interface. A plurality of fastening interfaces can preferably be provided.

The electronics unit with the sensor unit is thus protected by the second envelope section, in particular on the outside of the electronics. As a result, for example, a separate, complete housing for the electronics unit is formed, which can be variably attached to the vehicle. Furthermore, the actuating device can be adapted in a cost-effective manner for flat vehicle parts of any shape. As a result, the actuating device can be supplied as a single assembly. The assembly can be mounted in different positions on the vehicle as required being. In particular, an improved standardization for the actuating device can thereby be made possible. In this way, greater flexibility can be achieved when using the actuating device.

It is also conceivable in an actuating device according to the invention that the first envelope section has a potting compound or a cover element, in particular wherein the first envelope section is materially connected to the cladding element. The cover element can preferably be a rigid envelope section. For example, the cover element can have a hard component and / or a soft component made of plastic. The potting compound can in particular comprise an epoxy resin and / or an acrylate in order to protect the electronics unit from environmental influences, in particular from moisture. In particular, the potting compound can be transparent or opaque and / or opaque. A material bond between the first envelope section and the second envelope section can be implemented by means of the potting compound. In particular, the inside of the electronics and / or the outside of the electronics can be completely covered with potting compound. Preferably, at least the sensor unit is completely covered with potting compound. A seal can be implemented between the cover element and the second envelope section by means of a sealing means, in particular surrounding the cover element. The sealant can, for example, comprise a silicone or a sealing adhesive. Furthermore, the sealing means can simultaneously be used to form an integral fastening of the cover element on the second envelope section and / or on the cladding element. The first envelope section can be glued, welded, in particular friction-welded and / or laser-welded to the second envelope section.

In the case of an actuating device according to the invention, it can preferably be provided that the second envelope section comprises a shell element, in particular in which the electronics unit is arranged, in particular in a form-fitting manner. The shell element can preferably be a rigid envelope section. For example, the shell element can have a hard component and / or a soft component made of plastic. In particular, the shell element can be formed with the same material or essentially with the same material as the cover element. Furthermore, it is conceivable that the shell element extends over the electronics unit and / or the first envelope section is upside down. For the form-fitting attachment of the electronics unit, the second envelope section can have latching elements. The first and / or second envelope section and the electronics unit are preferably designed such that the electronics unit can be arranged in at most two orientations, preferably in only one orientation, between the first and second envelope sections. For this purpose, the electronics unit and the first and / or second envelope section can have positioning aids, in particular in the form of asymmetrical recesses and / or projections. In this way, incorrect assembly can be prevented intuitively.

In the case of an actuating device according to the invention, it can preferably be provided that the electronics unit is glued or welded to the first and / or second envelope section. For example, the electronics unit can be attached to the first and / or second envelope section by laser welding or friction welding. In particular, the potting compound can be distributed in such a way that the electronics unit is firmly attached to the first and / or second envelope section by the potting compound. Additionally or alternatively, it can be provided that the electronics unit is caulked with the first and / or second envelope section. By fixing the electronics unit on the first and / or second envelope section, movement within the envelope can also be prevented when the actuating device is in operation. Furthermore, further assembly steps can be simplified by fixing the electronics unit.

In an actuating device according to the invention, it can preferably be provided that the electronics unit has a circuit board, preferably in the form of a circuit card, with at least one, in particular capacitive or inductive, sensor element of the sensor unit for detecting the (preferably contactless) actuation action. In particular, the circuit board forms a basis for the electronics unit. The circuit board is preferably a multilayer circuit board. The sensor element can in particular be a sensor electrode. For example, the sensor element can comprise an electrical coil or a sensor surface in the form of an electrically conductive surface. As a result, a capacitive or inductive change in an electromagnetic field can be detected. Corresponding to the sensor element, a shield element, in particular in the form of a shield electrode, can be arranged on the inside of the electronics, through which an electrical field of the Sensor element can be aligned. Furthermore, it is conceivable that the sensor element is surrounded on the outside of the electronics by a screen element, through which an electrical field of the sensor element can be aligned. It is also conceivable that the electronics unit has a plurality of circuit boards on which various electronic components are distributed.

In an actuating device according to the invention, it can preferably be provided that the sensor unit has several, in particular similar, sensor elements for detecting the actuation action, whereby a direction of the actuation action can be identified. For example, the sensor elements can be produced by a printing and / or an etching process. The sensor elements can be configured inductively and / or capacitively. Additionally or alternatively, it is conceivable that the sensor elements are designed for optical detection and / or for detection by means of ultrasound. The direction of the actuation action can be detectable along a direction of arrangement of the sensor elements, in particular on the outside of the electronics. A gesture can thus be provided as the actuation action. If the function of the vehicle is to open a sliding door of the vehicle, for example a gesture along an opening direction of the sliding door can be provided as an actuation action. The sensor elements are preferably arranged in such a way that a horizontal gesture in front of the vehicle part triggers the function of the vehicle by the sensor unit.

In the case of an actuating device according to the invention, it can preferably be provided that the sensor elements are arranged on the circuit board in a regular pattern, preferably in a matrix-like and / or strip-like manner. Gesture recognition for recognizing the actuation action can be simplified by the regular pattern. A matrix-like arrangement can be understood to mean a two-dimensional arrangement of the sensor elements. For example, an arrangement of two by two sensor elements in one plane, in particular on the outside of the electronics, can form the smallest matrix-like arrangement. In the case of the strip-like arrangement, the sensor elements preferably have an elongate extension. In particular, in the case of the strip-like arrangement, the sensor elements are arranged next to one another in the form of a striped pattern. A distance between the sensor elements can be constant. Preferably, the sensor elements form in the strip-like arrangement on the Circuit board a pattern that only extends in one direction. It is also conceivable that the sensor elements are arranged in an irregular pattern on the circuit board. By arranging the sensor elements in a pattern, any complex actuation action can be detected in one plane. Furthermore, by arranging the sensor elements on a single printed circuit board, a structural unit can be made possible which is easy to handle during manufacture and offers short signal paths for detecting the actuation action. Manufacturing the sensor elements using a printing or etching process can also be simplified.

Furthermore, it is conceivable in an actuating device according to the invention that the electronics unit has an information unit by means of which the detection of the actuation action can be confirmed to the user, preferably on the outside of the panel, and / or the start of the actuation action can be signaled, in particular with the information unit being arranged on the circuit board . The information unit can be used to output a notice in the form of a signal to the user that the user can start the actuation action and / or that the actuation action has been detected by the sensor unit. The information unit can thus be used as a, in particular contactless, user interface. The information in the form of the signal can be given acoustically or visually, for example. It is also conceivable that the information is given in the form of the signal as a radio signal, for example to a smartphone or an electronic key belonging to the user. The information unit is preferably a unidirectional transmission unit. In particular, an input can be made by the user via the sensor unit. The information unit and the sensor unit can thus form a dialogue unit for bidirectional communication with the user. By arranging the information unit on the circuit board on which the sensor element is also arranged, manufacture of the actuating device can be simplified and signal paths of the electronics unit can be made simple and short.

In an actuating device according to the invention, it can preferably be provided that the information unit is an optical information unit and the second envelope section has at least one transparent window area through which an optical signal can be transmitted to the user by the information unit. The window area preferably comprises one or more transparent sections. For example the window area can comprise at least one recess in a cover material of the second cover section, which is closed by a light-permeable material. As a result, a seal of the cover can be maintained and the information unit can be arranged inside the cover. The first and / or second envelope section can be a two-component plastic injection-molded part. In the window area, a transparent material can preferably be injection molded onto an opaque and / or light-impermeable shell material of the second shell section. The second envelope section can also be formed completely by the translucent window area, it being possible for a coating and / or varnish and / or film to be present in order to make partial areas impermeable to light.

Furthermore, in an actuating device according to the invention, it can advantageously be provided that the information unit has a plurality of light transmitters for sending an optical signal to the user, the light transmitters being at least partially separated from one another by opaque separating sections. More complex information can be conveyed to the user as an indication by means of several light emitters. For example, the information that can be transmitted by the information unit can include a direction or the like. In particular, the light transmitters can be controlled dynamically, so that a dynamic display sequence can be implemented. The light emitters can be illuminants, in particular in the form of LEDs. It is also conceivable that the information unit comprises an LED or OLED display and the light emitters are formed by individual display elements. A display can be used to display symbols of different complexity to a user in order to be able to convey information about an expected actuation action, a confirmed actuation action and / or the like to a user. In particular, the window area can have a plurality of translucent sections which are separated from one another by the separating sections, in particular in the form of opaque and / or opaque material sections. The separating sections can be formed integrally with the second envelope section or separately from the second envelope section. For example, an intermediate element, in particular in the form of an insert, can be provided which comprises one of the separating sections or a plurality of separating sections. The intermediate element can be formed from foam rubber or another flexible material, for example. The intermediate element preferably has closed pores. As a result, the intermediate element cannot- be designed to be water-drawing. Furthermore, the intermediate element can be designed as an adhesive tape or attached to the cladding element and / or to the shell with an adhesive tape. In particular, the separating sections can be formed by the second envelope section and / or the intermediate element or can be formed by the cladding element. The separating sections can improve the ability to distinguish between the light source located behind it and the outer side of the cladding. The separating sections can preferably extend like ribs between the light emitters. The separating sections allow light from the light emitters to be directed in one direction, so that a user can assign the light to one of the light emitters, which can result in a clearer course in the event of dynamic activation of the light emitters. An encapsulated space is preferably formed around the light transmitter in each case or in groups by the separating sections. For this purpose, the separating sections can be formed circumferentially around the light transmitter and / or contact the printed circuit board in a sealing manner. In this way, for example, the outside of the electronics can be covered by filling a gap between the electronics unit and the cladding element with potting compound without covering the light transmitter with, in particular, opaque and / or light-impermeable potting compound.

In an actuating device according to the invention, it can preferably be provided that the electronics outside of the electronics unit is covered with potting compound, in particular wherein the electronics unit and / or the second envelope section has at least one receiving means for a potting nozzle for potting potting compound, so that the potting compound moves from the electronics inside to the electronics outside can be conveyed while the electronics unit is arranged on the second envelope section. By potting the electronics outside with the potting compound, an intermediate space between the electronics unit and the second envelope section can be filled with potting compound. This prevents moisture from collecting in the intermediate space and thereby negatively influencing a measurement by the sensor unit. By means of the receiving means, the casting compound can be reliably applied to the outside of the electronics after the electronics unit has been arranged on the cladding element. A casting nozzle can be understood to mean a tool or a part of a tool for distributing casting compound. In particular, a plurality of receiving means for the casting nozzle can be provided circumferentially around a printed circuit board of the electronics unit on a frame of the electronics unit and / or the second envelope section. This allows a reliable and homogeneous Distribution of the potting compound in the space should be made possible. Additionally or alternatively, it is conceivable that an elastic intermediate element is arranged in an intermediate space between the electronics unit and the second envelope section. The intermediate element preferably comprises a material with closed pores. Furthermore, the intermediate element can be elastically pretensioned against the second envelope section by the electronics unit and / or the first envelope section. As a result, the intermediate element can also be used to fill the gap, which prevents moisture from penetrating.

Furthermore, it is conceivable in an actuating device according to the invention that the sensor unit, the electronics unit and / or the shell are at least partially or completely symmetrical, in particular to a central plane of the actuating device, whereby the actuating device can be optionally mounted on two opposite sides of the vehicle. For example, only one control unit of the electronics unit can be reprogrammed for use on different sides of the vehicle. Furthermore, it is conceivable that a switch can be switched, by means of which an arrangement on the left or right-hand side in the direction of travel is established. Depending on the side of the vehicle, for example, the direction of the actuation action to trigger the function of the vehicle and / or a display course of the information unit can be defined. With sliding doors on both sides, for example, both doors to the rear of the vehicle can open, so that a mirrored actuation action is expected along the opening direction to automatically open the respective sliding door.

Furthermore, it is conceivable in an actuating device according to the invention that the electronic unit has a touch sensor for detecting pressure on the cladding element, whereby a further function of the vehicle can be triggered, in particular wherein the touch sensor comprises an LDC sensor (inductive sensor). A further actuation action by the user can be made possible by the touch sensor. Another function of the vehicle can be, for example, locking and / or unlocking a lock. Additionally or alternatively, the touch sensor can be used to bring about an emergency stop when a door is automatically opened and / or closed. For example, an electrically conductive target element can be provided on the second envelope section and / or on the cladding element Change in distance when the user presses on the vehicle part and / or the cladding element can be registered by the touch sensor. A plurality of LDC sensors can preferably be provided, in particular in order to verify a detection of the further actuation action and / or to enable a wider actuation area on the vehicle part and / or on the cladding element. If, for example, it is provided that the function that can be triggered by the sensor unit is only enabled after the further function has been activated, the probability of an incorrect triggering can be significantly reduced.

In an actuating device according to the invention, it can preferably be provided that the electronic unit has an identification means for identifying the user, in particular wherein the identification means has a radio element for contactless data exchange with an ID transmitter. The ID transmitter can be understood to mean, for example, a smartphone and / or an electronic key of the user. The identification means can in particular comprise an NFC interface (Near Field Communication interface), a BLE interface (Bluetooth Low Energy interface) and / or UWB interface (Ultra-wideband interface). As a result, the identification means can enable the user to be authenticated. In particular, the identification means for identifying the user can be brought into a communication link with a vehicle control unit. In particular, the identity check can be carried out by the vehicle control unit on the basis of the data exchange between the identification means and the ID transmitter.

It is also conceivable in an actuating device according to the invention that the electronics unit has a proximity sensor for detecting an approach of a user, in particular wherein the proximity sensor is designed for capacitive detection of the approach. Thus, in particular, a further capacitive sensor can be provided in addition to the sensor unit by means of the proximity sensor. The proximity sensor can, for example, wake up the sensor unit, the touch sensor and / or the identification means when the approach of the user is recognized. As a result, energy can be saved during the operation of the actuating device. Furthermore, when the approach is detected, the proximity sensor allows the Note unit can be activated. For example, an activation state of the actuating device can thereby be signaled to a user.

Furthermore, in an actuating device according to the invention, it can advantageously be provided that the printed circuit board has several conductor layers, the sensor unit being arranged on a first conductor layer and the touch sensor and / or the identifier on a further conductor layer. The conductor layers can be electrically insulated from one another. In particular, a sensor plane can be formed by each of the conductor layers. As a result, a compact design of the printed circuit board and / or the electronics unit can be achieved.

Furthermore, in the case of an actuating device according to the invention, it can advantageously be provided that the electronics unit has a control unit for evaluating sensor signals from the sensor unit and for activating the information unit as a function of the sensor signals. For example, the sensor signals of the sensor unit can be digitized and forwarded directly in the electronics unit by the control unit. Furthermore, it is conceivable that a direction of the actuation action can be recognized by the control unit on the basis of the evaluation of the sensor signals. By evaluating the sensor signals in the electronics unit, short signal paths can be made possible. Furthermore, the information unit can be activated as a function of the sensor signals, whereby the user can be given feedback on the detection of the direction of the actuation action.

According to a further aspect of the invention, a vehicle is provided. The vehicle has a vehicle part with a flat paneling element. Furthermore, the vehicle has an actuating device, in particular an actuating device according to the invention, for triggering a function of the vehicle by a user. The actuating device comprises an electronics unit with a sensor unit for detecting an actuation action by the user to trigger the function of the vehicle, an electronics outside on which the actuation action of the user can be detected by the sensor unit, and an electronics inside opposite the electronics outside. Furthermore, the actuating device comprises a first envelope section for protecting the electronics inside the electronics unit and a second envelope section for protecting the electronics outside of the electronics unit. The first and second envelope sections form, in particular around the electronics unit, a closed envelope which is arranged in a modular manner on the cladding element.

Thus, a vehicle according to the invention has the same advantages as have been described in detail with reference to an actuating device according to the invention. The vehicle is preferably a motor vehicle. The vehicle part preferably further comprises a B-pillar of the vehicle and / or an interior part of the vehicle. The function that can be triggered by the actuation device can include an automatic movement of the vehicle part.

The flat design of the cladding element can in particular be understood to mean that the cladding element has a flat, in particular shell-like, flat extension. For example, the cladding element can be designed with thin walls. The cladding element can in particular be a panel for a body part of the vehicle. For example, an outer surface of the vehicle part can be formed by the cladding element. The outer surface can be an interior surface or an outer surface of the vehicle. A visible surface of the vehicle part can preferably be formed by the cladding element. For example, the cladding element can be arranged behind a glass pane, in particular with respect to an outside area of the vehicle. In this case, the actuating device is preferably arranged on a door of the vehicle, in particular a side and / or sliding door. As a result, optical and / or electromagnetic signals can be transmitted to a user located in front of the vehicle part and / or can be received by the user through the sensor unit. The cladding element can preferably be integrated into a body surface and / or an optical system of a body surface of the vehicle, in particular in order to enable a side door of the vehicle to be opened as a function that can be triggered by the actuation action. It is conceivable that the cladding element can be integrated into a B-pillar of the vehicle. Consequently, in this case the actuating device is optionally arranged on the B-pillar. In particular, the cladding element has a plastic or consists of a plastic. Due to the sensor unit, the cladding element can be designed without handles and / or switches. In particular, the cladding element a cladding inside and a cladding outside. The inside of the cladding lies opposite the outside of the cladding in relation to the cladding element in particular. For example, the vehicle part can have a lining interior in which electrical components can be arranged. The inside of the cladding can be oriented towards the interior of the cladding in particular. The casing can in particular be caulked or screwed to the cladding element. As a result, an advantageous possibility of fastening, in particular under pretension, can be created.

The electronics unit with the sensor unit is thus protected by the cladding element, as a result of which the actuating device can be mounted on the vehicle part in a cost-effective manner. Furthermore, the freedom of design of the cladding element can be increased if the electronic unit is arranged in a modular manner on the cladding element when the vehicle part is assembled. As a result, a greater overall flexibility in the manufacture of the actuating device can also be achieved.

In a vehicle according to the invention it can preferably be provided that an elastic intermediate element is arranged in an intermediate area between the cladding element and the actuating device, preferably between the cladding element and the shell of the actuating device, in particular wherein the actuating device is biased against the intermediate element or wherein the actuating device is through the intermediate element is attached to the cladding element, preferably cohesively. In particular, the intermediate element is arranged on the lining inside of the lining element and / or on the electronics outside of the electronics unit on the casing. The intermediate element can advantageously reduce the generation of noise, in particular if the actuating device is pretensioned against the intermediate element. The intermediate element can be compressed when the actuating device is biased against the intermediate element. The intermediate element can preferably have a closed-pore material, in particular which is not designed to be water-absorbing as a result. This can prevent moisture from accumulating in the space. Furthermore, the intermediate element preferably comprises a window area through which an optical signal from the information unit can be transmitted. The intermediate element preferably further comprises separating sections in order to optically separate the light emitters of the information unit and / or to guide and / or channel light emitted along a predetermined light path. Furthermore, it can be provided that the intermediate area is sealed by a circumferential sealant. To pretension the intermediate element, the actuating device can, for example, be clipped or screwed to the cladding element. The intermediate element is preferably arranged between the actuating device and the cladding element in such a way that a sensor area of the sensor unit runs, in particular completely, through the intermediate element. For example, the intermediate element can be arranged between the sensor element of the sensor unit or the sensor elements of the sensor unit and the cladding element.

Furthermore, it is conceivable that the intermediate element comprises an, in particular double-sided, adhesive tape, by means of which the actuating device is attached to the cladding element. This can improve the performance of the sensor unit. In particular, the intermediate element can be arranged on the second envelope section, i.e. in particular directly between the second envelope section and the cladding element. The intermediate element can extend at least partially or completely over an outer surface of the second envelope section. For example, the shell can be cuboid, i.e. in particular with four side surfaces and two main surfaces. The first and second envelope sections are preferably connected at the side surfaces and / or sealed by the sealing means. The main surfaces can be oriented parallel or at least substantially parallel to the inside of the electronics, to the outside of the electronics and / or to the inside of the cladding. The intermediate element can be arranged on one of the main surfaces, in particular so that the intermediate element is arranged directly between the main surface and the cladding element.

It is also conceivable in a vehicle according to the invention and / or an actuating device according to the invention that an intermediate element for arrangement in an intermediate area between the cladding element and the shell is formed in one piece with the second shell section. For example, the second envelope section can be produced in a multi-component plastic injection molding process. In particular, it can The intermediate element can be designed as a, in particular closed-pore, soft component. As a result, the shell can be pretensioned against the cladding element, in particular as a result of which the generation of noise can be prevented or reduced.

A method according to the invention thus brings the same advantages as have already been described in detail with reference to an actuating device according to the invention and / or a vehicle according to the invention. The arrangement and the closing can also be carried out at the same time if, for example, the first envelope section has a potting compound and is potted with the second envelope section and the electronics unit. The flat cladding element is preferably a cast part, in particular a multi-component plastic injection-molded part. Furthermore, the cladding element can have a non-conductive material, in particular a non-conductive plastic, as a result of which the cladding element is permeable to an electrical field of the sensor unit. When the electronics unit is provided, a printed circuit board can be fitted with electronic components and printed become. Additionally or alternatively, electronic components can be etched when the electronic unit is provided. When the electronics unit is arranged between the first and second envelope sections, a material connection between the first envelope section and the second envelope section and / or with the electronics unit can be achieved. In particular, when arranging the electronics unit between the first and second casing section, it can be provided that the electronics unit is first arranged in the first or second casing section before the respective other casing section is added.

The attachment of the shell to the cladding element of the vehicle part can in particular take place by arranging an intermediate element between the shell and the cladding element. The intermediate element can, for example, create a material bond with the shell and the cladding element. The intermediate element can preferably be designed as a double-sided adhesive tape.

The electronics unit with the sensor unit is thus protected by the casing independently of the cladding element, as a result of which the actuating device can be mounted on the vehicle part in a cost-effective manner.

Furthermore, in a method according to the invention, it can advantageously be provided that the shell is pretensioned, in particular mechanically, against a cladding inside of the cladding element when the shell is fastened to the cladding element, in particular with an intermediate area between the cladding element and the shell being sealed. In this case, an elastic intermediate element can be arranged in the intermediate area in order to completely fill the intermediate area at least in the area of the sensor elements of the sensor unit. For example, the shell can be caulked or screwed to the cladding element under pretensioning.

FIGS. 11 to 13 different conductor layers of a printed circuit board of the electronics unit.

In the following description of some exemplary embodiments of the invention, identical reference symbols are used for the same technical features in different exemplary embodiments.

Figure 1 shows a vehicle 1 according to the invention in a first embodiment with a vehicle part 2, which is designed in particular as a vehicle door in the form of a sliding door. The vehicle 1 also has an actuation device 10 for triggering a function of the vehicle 1. The function can be, for example, automatic opening and / or closing of the sliding door. In this case, the function takes place in particular as a function of an actuation action 200 by a user. For example, the opening of the vehicle part 2 can be initiated by an actuation action 200 in the form of a gesture along an opening direction of the vehicle part 2 or the closing of the vehicle part 2 can be initiated by an actuation action 200 in the form of a gesture opposite to the opening direction. The actuation device 10 can - as shown by way of example - be arranged on a B-pillar 2.1 and / or on a vehicle part 2, in particular in the form of a door or sliding door, of the vehicle 1.

As shown in FIG. 2, the actuating device 10 is arranged on a flat paneling element 11 of the vehicle part 2. The flat design of the cladding element 11 can extend, for example, along part of the body of the vehicle 1 or behind a glass pane of the vehicle part 2. The cladding element 11 comprises a cladding outside 11.2 and a cladding inside 11.1. The cladding outer side 11.2 preferably forms a surface of the vehicle part 2 that is visible from outside the vehicle 1 and / or a part of a body surface 1.1. For example, the cladding element 11 can be part of a cladding in the area of a B-pillar 2.1 of the vehicle 1.

The actuating device 10 is arranged on the cladding element 11, in particular directly or indirectly with an intermediate element 51. The actuating device 10 comprises an electronics unit 12, which has an electronics outside 12.2 and an electronics inside 12.1. The electronics outside 12.2 is oriented towards the lining inside 11.1 of the lining element 11. The electronics inside 11.1 is opposite the electronics outside 11.2. In particular, the electronics inside 11.1 is oriented towards a vehicle interior of the vehicle 1 and / or a panel interior of the vehicle part 2. However, it is also conceivable that the lining element 11 is part of an interior lining of the vehicle 1. In this case, the electronics inside 12.1 can be oriented towards an outside of the vehicle 1, for example.

Furthermore, the electronics unit 12 has a sensor unit 20 for detecting the actuation action 200 of the user. The sensor unit 20 is preferably arranged on the electronics outer side 12. 2 of the electronics unit 12. The arrangement of the electronics unit 12 on the lining inside 11.1 of the lining element 11 the actuating device 10 can be at least partially covered by the cladding element 11. To protect the electronics unit 12, the actuating device 10 also has a first and a second cover section 31, 32, which form a closed cover 30 around the electronics unit 12. The first envelope section 31 is preferably arranged on the electronics inside 12.1 and the second envelope section 32 on the electronics outside 12.2 of the electronics unit 12. Possible configurations of the casing 30 are shown by way of example in FIGS. 3 and 4.

FIG. 3 shows an envelope 30 in which the first envelope section 31 is formed by a potting compound 31.1. The electronics unit 12 has a printed circuit board 13 on which the sensor unit 20 is arranged. The circuit board 13 of the electronics unit 12 is preferably enclosed in a frame 14, by means of which the electronics unit 12 is easier to handle during assembly and / or can be fastened to the casing 30 in a form-fitting manner. The frame 14 can also form part of the shell 30. The potting compound 31.1 is materially connected to the second envelope section 32 and preferably completely covers the electronics inside 12.1. Furthermore, the electronics outer side 12.2 in particular can also be at least partially or completely covered with the potting compound 31.1, so that at least the sensor unit 20 is covered by the potting compound 31.1. The second envelope section 32 can comprise a shell element 32.1 into which the electronics unit 12 is inserted. For this purpose, the electronics unit 12 can be arranged in a form-fitting manner in the second envelope section 32 directly or, for example, indirectly via the frame 14. The sensor unit 20, the electronics unit 12 and / or the casing 30 is preferably designed at least partially symmetrically to a center plane 10.1, as a result of which the actuating device 10 can be optionally mounted on two opposite sides of the vehicle.

Furthermore, the electronics unit 12 has an information unit 40 by means of which the detection of the actuation action 200 can be confirmed to the user, in particular on the cladding outside 11.2, and / or the start of the actuation action 200 can be signaled. The notification unit 40 comprises a plurality of light emitters 42 for sending an optical signal to the user. The light emitters 42 can in particular be illuminants in the form of LEDs. The light generators 42 are arranged in a row with respect to one another and separated by separating sections 43. The arrangement of the Light emitters 42 in a row can, for example, be able to display to a user a direction of the actuation action 200 detected by the sensor unit 20 by activating the light emitters 42 one after the other along the row. The separating sections 43 can be formed at least in sections by an intermediate element 51, which is arranged in an intermediate region 50 between the cladding element 11 and the cover 30, by the second cover section 32 and / or by the cladding element 11. In particular, the separating sections 43 are opaque and / or opaque, so that the light emitted by the light emitters 42 can be conducted separately for each light emitter 42 to the cladding outer side 11.2. Preferably, the intermediate element 51 can also be designed to be elastic and can be pretensioned against the casing 30. Additionally or alternatively, it is conceivable that the shell 30 is fastened to the cladding element 11 by the intermediate element 51, in particular in a materially bonded manner. For example, the intermediate element 51 can comprise a double-sided adhesive tape. In particular if the separating sections 43 and / or the intermediate element 51 are at least partially formed by the second envelope section 32, each of the light emitters 42 can be encapsulated by the second envelope section 32, in particular circumferentially, so that when the electronics unit 12 is encapsulated with the encapsulation compound 31.1 the light transmitter 42 remain free of potting compound 31.1. Furthermore, the cladding element 11 and / or the second envelope section 32 has a light-permeable window area 41 through which an optical signal from the information unit 40 can be transmitted to the user. For example, the window area 41 can have a transparent window material 41.1, in particular a transparent plastic. The transparent window material 41.1 can be injection-molded onto an opaque and / or light-impermeable base material of the cladding element 11 and / or the second envelope section 32 during production of the cladding element 11 and / or the second envelope section 32, for example as a plastic injection-molded component.

Additionally or alternatively, the light emitters 42 can also be parts of a display or the like. Furthermore, it is additionally or alternatively conceivable that the notification unit 40 can output an acoustic notification or a notification in the form of radio signals to the user. It is also conceivable that the separating sections 43 are formed by the cladding element 11. As shown in FIG. 4, the separating sections 43 can be formed in one piece with the cladding element 11. In this case, the separating sections 43 preferably extend in the manner of ribs as far as the printed circuit board 13. FIG. 4 also shows a cover 30 in which the first cover section 31 is formed by an, in particular, rigid, cover element 31.2. The cover element 31.2 can, for example, have a hard plastic and can be placed on the second envelope section 32 with the electronics unit 12 during the assembly of the actuating device 10. In this case, a seal between the cover element 31.2 and the second envelope section 32 can advantageously be implemented by a sealing means 33, in particular surrounding the cover element 31.2. The sealing means 33 can comprise a silicone, for example. It is conceivable that the sealing means 33 simultaneously forms an integral fastening of the cover element 31.2 on the cladding element 11 and / or intermediate element 51.

FIG. 5 shows a further exploded view of the actuating device 10. The casing 30 has a mechanical fastening interface 34 for fastening the actuating device 10 to a counter-fastening interface 11. 3 of the cladding element 11. The casing 30 can preferably be screwed or caulked to the cladding element 11. Furthermore, an electrical connection 35 can be provided, through which the electronics unit 12 can be or is connected to vehicle electronics and / or vehicle power supply. For this purpose, the electrical connection 35 can protrude from the casing 30. In particular, the electrical connection 35 can be potted with the sealing compound 33 and / or the potting compound 31.1.

FIG. 6 shows a method 100 for producing the actuating device 10 in a schematic representation of the method steps. Provision is made for the electronic unit 12 to be provided 101. Furthermore, the cladding element 11 can be provided, for example by producing the cladding element 11 in a plastic injection molding process and / or removing it from a store. When providing 101 the electronics unit 12, the sensor unit 20 and / or further electrical components can be arranged on the circuit board 13 of the electronics unit 12, in particular by a printing and / or etching process. The electronic unit 12 is then arranged 102 between the first and second envelope sections 31, 32 and the first and second envelope sections 31, 32 are closed 103 to form the closed envelope 30. The arrangement 102 and the closing 103 can also be carried out simultaneously if, for example, the first envelope section 31 has a potting compound 31.1 and is encapsulated with the second envelope section 32 and the electronics unit 12. Furthermore, the casing 30 is fastened 104, in particular through the at least one fastening interface 34 on the cladding element 11, preferably so that the electronics outside 12.2 of the electronics unit 12 is oriented toward the cladding inside 11.1 of the cladding element 11. Additionally or alternatively, the sealing means 33 can be applied during the fastening 104 of the sheath 30, as shown in FIG.

Figures 7 and 8 show an electronics unit 12 for the actuating device 10 in one possible embodiment. In this case, a circuit board 13 of the electronics unit 12 is arranged in a frame 14, by means of which fastening to a cladding element 11 can be simplified. For this purpose, the frame 14 has latching elements 14.1 into which the circuit board 13 can be clipped. Furthermore, the frame 14 preferably has one or more receiving means 14.2 for a potting nozzle for potting potting compound 31.1, whereby the potting compound 31.1 can advantageously be distributed from an electronics inside 12.1 over an electronics outside 12.2. FIG. 7 shows the electronics unit 12 from the electronics inside 12.1 and FIG. 8 shows the electronics unit 12 from the electronics outside 12.2, which is opposite the electronics inside 12.1. On the electronics outer side 12.2, sensor elements 21 of a sensor unit 20 are arranged in a regular pattern on the circuit board 13 in a matrix-like manner. Each of the sensor elements 21 forms a capacitive surface. The sensor unit 20 is therefore in particular a capacitive sensor, as a result of which a contactless actuation action 200 can be recognized by the sensor unit 20. Due to the matrix-like arrangement of the sensor elements 21, a direction of the actuation action 200 can also be identified. For example, when a user sweeps past a cladding outer side 11.2 of the cladding element 11, an electrical field of the sensor elements 21 changes one after the other as a function of the direction of the actuation action 200. The direction of the actuation action 200 can be deduced from the sequence of detection by the sensor elements 21. For this purpose, the electronics unit 12 preferably has a control unit 25 for evaluating sensor signals from the sensor unit 20. Furthermore, an information unit 40 can be activated by the control unit 25 in order to provide the user, for example, with the Detection of the actuation action 200 and / or the direction of the actuation action 200 to be displayed. In each case corresponding to the sensor elements 21, shielding elements 21.1 for shielding the sensor elements 21 are arranged in a matrix-like manner on the electronics inside 12.1. In particular, an opposing screen element 21.1 is assigned to each of the sensor elements 21.

Figures 9 and 10 show an electronics unit 12 for the actuating device 10 in a further possible embodiment. The electronics unit 12 essentially corresponds to the electronics unit 12 of the exemplary embodiment in FIGS. 7 and 8, but the sensor elements 21 of the sensor unit 20 are designed and arranged in the form of strips. While several directions of an actuation action 200 can also be detected in a matrix-like arrangement, the direction of the actuation action 200 in the case of the strip-like sensor elements 21 can be detected along a straight line. However, the strip-like arrangement of the sensor elements 21 results in a larger capacitive field in each case with the same installation space, as a result of which incorrect identification can be reduced. On an electronics inside 12.1, corresponding to the strip-like configuration of the sensor elements 21, shielding elements 21.1 are arranged in a strip-like manner and corresponding to the sensor elements 21.

In addition to the sensor unit 20, the electronics unit 12 preferably includes a touch sensor 22, an identification means 23 and / or a proximity sensor 24, as shown in FIGS. 11 to 13. The identification means 23 can in particular comprise a radio element 23. 1, in particular in the form of an electrical coil, which can be printed onto the circuit board 13 as a circumferential conductor track. The identification means 23 can enable a contactless exchange of data with an ID transmitter of the user. Thus, the identification means 23 can preferably comprise an NFC interface, a BLE interface and / or a UWB interface. As a result, the user can be identified and / or authenticated, in particular by vehicle electronics with which the identification means 23 can be brought into a data communication connection. Automatic locking and / or unlocking of the vehicle 1 can be provided as a function of the identification of the user by the identification means 23. The touch sensor 22 can comprise, for example, an LDC sensor, by means of which a deformation due to a touch or a pressure on the Cladding element 11 can be seen. Depending on the actuation of the touch sensor 22, a further function of the vehicle 1, such as an automatic opening movement and / or an automatic closing movement of the vehicle part 2 or an emergency stop when the vehicle part 2 is moved, can be triggered. The additional proximity sensor 24 in particular can enable, for example, a wake-up signal to be sent to other electronic components as a function of the detection of the user's approach. The touch sensor 22, the identification means 23 and / or the proximity sensor 24 are preferably arranged in different conductor layers 13.1, 13.2 on the circuit board 13. For example, according to FIG. 11, the sensor unit 20 and the identification means 23 can be arranged together on a first conductor layer 13.1. The touch sensor 22 and the proximity sensor 24 can also each be arranged on a further conductor layer 13.2 of the circuit board 13. A compact design of the actuating device 10 can be achieved through a multilayer design of the printed circuit board 13, by means of which the actuating device 10 can advantageously be arranged on the cladding element 11 in a small installation space. By means of the touch sensor 22, the identification means 23 and / or the proximity sensor 24, the actuating device 10 can thus create a convenient operating option for the user with a high degree of automation.

The above explanation of the embodiments describes the present invention exclusively in the context of examples. Of course, individual features of the embodiments can be freely combined with one another, provided that they are technically sensible, without departing from the scope of the present invention.
