Description

State of the art

[0001] From DE 10 2018 103 350 A1 a control element for a vehicle interior is known. Disclosure of the invention

[0002] A proposed input device for entering a command comprises several control elements, each control element comprising a control element housing and a control element circuit board. The control element housing has a first surface facing the user and a second surface opposite the first surface, facing away from the user. The control element circuit board is arranged on the second surface of the control element housing. The input device has several actuators for moving one or more of the control elements between a starting position and an end position.Furthermore, the input device has a receiving element with a user-facing surface for receiving the operating elements, wherein the user-facing surface of the receiving element and the first surface of the operating elements are arranged on the same plane in the initial position, and wherein the first surface of the operating elements is extended relative to the receiving element in the end position. The receiving element also has a stop for several and / or individual operating elements, wherein the operating elements rest against the respective stop in the initial position. The input device further comprises a printed circuit board, wherein the actuators are arranged on or attached to the base printed circuit board.

[0003] The advantage lies in the fact that the proposed input device enables the operation of one or more functions, for example, in a vehicle. For instance, one or more displays in a vehicle can be controlled using the proposed input device. The controls of the input device are extended specifically when needed. Preferably, the input device or control element is extended and can then receive a command, provided this is necessary and / or desired by a user. This prevents the user from being distracted by too many elements on a user interface. If the input device is installed in a vehicle, the user could, for example, be a vehicle occupant, such as the driver. This allows the vehicle occupant to...The driver is not distracted by too many elements in the vehicle interior, thus increasing road safety. Furthermore, by making the control element disappear when not in use, injuries to the user and / or damage to the input device, for example from bumping into it or getting caught on it, can be reduced.

[0004] A further advantage is that the control element can be moved all the way to its starting position. This allows the control element to be reliably and / or consistently positioned in the same location, and thus, in particular, to disappear completely into the receiving element. This results in a reliably and / or consistently flush position of the control element with the receiving element in the starting position. Advantageously, this allows the same starting position of the control element to be reached in every cycle. Furthermore, the use of stops for the control elements saves costs by eliminating the need for more expensive and / or additional components, such as high-precision actuators.

[0005] In one exemplary embodiment, a positive fit can be formed between the operating element and the receiving element in the initial position. In a further development, a circumferential positive fit can be formed between the operating element and the receiving element in the initial position.

[0006] This advantageously enables a positive fit and, in particular, a circumferential pressing of the control element or its flanks against the receiving element or against the opening flanks of the receiving element when the control element is lowered into its starting position. This allows the control element to be reliably and / or consistently positioned in the same location or position in its starting position, and thus, in particular, to disappear into the receiving element. A further advantage is that gaps between the control element and the receiving element are closed, especially in the starting position. This protects the area located below the control element in relation to the user. For example, it prevents the ingress of dust, dirt, dirt particles, and / or water or moisture into crevices and / or into the area of ​​the input device located below the control element.This can be reduced. In other words, moisture ingress through the gap, which is closed in the initial position, can be prevented.

[0007] In an advantageous embodiment, a command can be determined by moving the control element in a vertical direction and / or by pressing on the control element and / or by touching the control element. Advantageously, the control element can be moved, particularly in a vertical direction, and / or pressure can be applied to the control element for actuation, and / or the control element can be touched for actuation. This allows a command to be issued via the control element and thus the input device to be recognized, particularly reliably and / or securely. This enables a corresponding action to be carried out in response to the command.

[0008] Preferably, the first surface of the control elements can be designed as a touch-sensitive surface. This allows a user to enter commands via the touch-sensitive surface in a particularly safe and / or reliable manner.

[0009] Advantageously, a further circuit board, the control element circuit board, can be arranged in the control element, preferably directly beneath the user-facing surface of the control element. This circuit board comprises capacitive sensors and / or one or more electrodes. In a further development, several electrodes can be arranged along an edge of the control element circuit board. Preferably, this allows the first surface of the control element to be designed as a touch-sensitive surface, enabling a user to input commands via the surface in a particularly safe and / or reliable manner. Furthermore, the arrangement of several electrodes around the edge of the control element allows not only a simple tap but also a swipe touch, for example, moving a finger along the edge of the control element, thus expanding the possibilities for interaction.

[0010] In one exemplary embodiment, a controller and / or one or more actuators for generating haptic feedback and / or an interface for connecting the control element circuit board to the base circuit board on which the actuators are mounted can be arranged on the control element circuit board. Preferably, this allows the first surface of the control element or the control element circuit board to be designed as a touch-sensitive surface, enabling a user to input commands via the touch-sensitive surface safely and / or reliably. A further advantage is that the user can be given haptic feedback. Advantageously, a user can keep their eyes on the road and have a command input confirmed by haptic feedback, thereby increasing road safety.

[0011] In a further development, the input device can include a snap disc to generate click feedback and / or to implement a contact switch. The snap disc can be arranged, in particular, between the actuator and the control element and / or be designed as part of the actuator assembly. Preferably, this allows a switch to be integrated safely and / or reliably, enabling a user to input commands safely and / or reliably. Furthermore, the user can advantageously be given haptic feedback similar to a push button, allowing the user to keep their eyes on the road and confirming a command input through haptic feedback, thereby increasing road safety.

[0012] In a further development, the input device can have a sensor to detect when a user approaches and / or moves away from the input device. The control element moves to its end position when the sensor detects that the user is approaching, and to its starting position when the sensor detects that the user is moving away. This allows the device to detect when a user intends to use it, with the control element then moving to its end position as soon as a user is detected approaching. After use and / or when a user moves away from the input device, the control element can then be moved back to its starting position.This allows the control element to be available when needed, thus preventing user distraction when the user does not require it. If the input device is located in a vehicle, the reduced distraction for the user, especially a vehicle occupant or driver, can increase road safety.

[0013] In an advantageous embodiment, the input device can include a lighting unit with one or more light sources, wherein the one or more light sources are arranged on the receiving element and / or in the control element. In a further development, the input device can alternatively or additionally include a lighting unit with one or more light sources and one or more light guides, wherein the one or more light sources are arranged on the circuit board and the one or more light guides are arranged between the circuit board and the user-facing surface of the receiving element. The advantage is that the input device, and in particular the control elements, are more visible to the user and can therefore be perceived safely and / or reliably, especially when input is expected or necessary.This allows, for example, indirect lighting of the controls. The advantage lies particularly in the improved presentation of the controls, as the lighting becomes more visible and the user can perceive it safely and / or reliably, thus facilitating the input of a command.

[0014] Furthermore, a method for moving a control element of an input device is proposed, comprising the steps of controlling the actuator to move the control element, wherein the control element is moved from the starting position to the end position by means of the actuator, controlling the actuator to move the control element, wherein the control element is moved from the end position to the starting position by means of the actuator.

[0015] In a further development, the method can include a step of detecting a user's approach using a sensor, whereby the control element is then moved to its end position when the sensor detects the user's approach, and a step of detecting a user's departure using the sensor, whereby the control element is then moved back to its starting position when the sensor detects the user's departure. This allows the control element to be available when needed, thereby increasing road safety in particular.

[0016] Furthermore, a method for entering a command by means of an input device is proposed, comprising the steps of: controlling the actuator to move the control element, wherein the control element is moved from the starting position to the end position by means of the actuator; detecting an input of a command by a movement of the control element performed by a user and / or by a touch of the control element performed by a user and / or by a pressure applied to the control element by a user; controlling the actuator to move the control element, wherein the control element is moved from the end position to the starting position by means of the actuator.

[0017] Furthermore, a method for assembling an input device is proposed, comprising the steps of: Providing the base circuit board, wherein actuators in particular can be arranged and / or connected and / or are arranged and / or connected on or to the base circuit board, Arranging the actuators on the base circuit board and / or connecting the actuators to the corresponding interfaces on the base circuit board, if the actuators are not already arranged and / or connected on the base circuit board; arranging the mounting element on the circuit board.

Embodiments of the invention:

[0019] Fig. Figure 1 shows a schematic representation of part of an input device 20. The input device 20 is designed for inputting a command. The input device 20 can, for example, be arranged in a vehicle, for instance according to Fig. 10. The input device 20 has several operating elements 22. In this advantageous embodiment, a part of the input device 20 is shown, and only one operating element 22 is depicted. The other operating elements 22 of the input device 20 can be configured according to the operating element 22 shown. Fig. 1. The control element 22 comprises a control element housing 21 and a control element circuit board 23. The control element housing 21 has a first surface 24 facing the user and a second surface 25 opposite the first surface 24, facing away from the user. The control element circuit board 23 is arranged on the second surface 25 of the control element housing 21. The control element 22 can, in particular from the user's viewing direction, be, for example, round, oval, rectangular, or rectangular with rounded corners or with multiple corners or with multiple rounded corners.

[0020] The input device 20 has several actuators 26 for moving one or more of the control elements 22 between a starting position and an end position. In this advantageous embodiment, a part of the input device 20 is shown, and only one actuator 26 is depicted. The other actuators 26 of the input device 20 can be arranged according to the actuator 26 shown. Fig. 1. One, one of, or more of the control elements 22 can thus be moved from the starting position to the end position and back again by means of the actuator 26. In this advantageous embodiment, the input device 20 has an actuator 26 for the one control element 22, whereby the one control element 22 can be moved by means of the actuator 26. Furthermore, the actuator 26 is connected to the control element 22 by means of a connecting element 27, in particular in the form of a rod and / or plunger, which is arranged parallel to the direction of movement of the control element 22. The connecting element 27 is arranged at one end on the actuator 26 and at one end on the control element 22.The connecting element 27 can, for example, be arranged on the control element housing 21 or via another element of the control element 22, for example a control element carrier 33, which in turn is arranged on the control element housing 21.

[0021] The actuator 26 can be designed, for example, as an electric, hydraulic, pneumatic, magnetic actuator and / or as an actuator based on shape memory materials. The actuator 26 can, for example, be designed as a linear motor. Advantageously, the actuator 26 moves the control element 22 back and forth between different positions, preferably the starting position and the end position. The movement can be performed in two stages, several stages, and / or continuously. In an advantageous embodiment, the positions, in particular the end position and / or starting position or positions in between, can be selectively controlled or assumed by the control element 22 by means of the actuator 26. The one, one of the, or more control elements 22 is or are, in particular, movable by means of the actuator 26 perpendicular to the user-facing surface 29 of the receiving element 28.In other words, one, one of the, or more control elements 22 can be moved or traversed perpendicular to the user interface. In this advantageous embodiment according to . Fig. Figure 1 shows the control element 22 in its initial position. The arrangement of the control element 22 in its final position can be described below. Fig. 2, Fig. 6, Fig. 7 and / or Fig. 8. In an alternative embodiment, the control element 22 can alternatively or additionally be lowered from the starting position to the end position, which can create a hollow or depression.

[0022] The input device 20 further comprises a receiving element 28 with a user-facing surface 29 for receiving one or more control elements 22, wherein the user-facing surface 29 of the receiving element 28 and the first surface 24 of the one or more control elements 22 are arranged on the same plane in the initial position, and wherein the first surface 24 of the control element 22 is extended relative to the receiving element 28 in the end position, see Fig. 2, Fig. 6, Fig. 7 and / or Fig. 8. In its initial position, the control element 22 is preferably arranged in or within the receiving element 28 and thus disappears within the receiving element 28. This prevents any protrusion or recession of the control element 22 from or into the receiving element 28 in its initial position. The receiving element 28 can, for example, be designed as a housing or support, wherein the housing or support accommodates the control element 22 and the actuator 26. In an exemplary embodiment, the receiving element 28 can be part of a dashboard, storage compartment, and / or armrest, in particular a center console, of a vehicle, or be arranged in or on a dashboard, storage compartment, and / or armrest, in particular in a center console, of a vehicle (see Figure 1). Fig. 10.

[0023] The receiving element 28 further comprises a stop 30 for several and / or each of the operating elements 22, wherein the operating elements 22 rest against the respective stop in their initial position. In a further development, the stop 30 can, for example, be designed in the form of a chamfer which is mirrored at the edge of the operating element 22, see, for example, according to Fig. 3. In an advantageous embodiment, a positive fit can be formed between the operating element 22 and the receiving element 28 in the initial position. This positive fit can be formed, for example, by a stop. In a further development, a circumferential positive fit can be formed between the operating element 22 and the receiving element 28 in the initial position.

[0024] In an alternative embodiment, the receiving element 28 can have a recess in the form of the control element 22. Advantageously, the recess is designed such that the control element 22 can be inserted or lowered into the recess in its initial position. For example, the control element 22, when in its initial position, can fill the recess.

[0025] The input device 20 has a side 32 facing the user, with the first surface 24 of the control element 22 oriented towards the first side 32. A user, or a user's hand, can be positioned on the first side 32 of the input device 20 for operating the input device 20.

[0026] The input device 20 further comprises a base circuit board 31, wherein the actuator 26 or actuators 26 are arranged on or at the base circuit board. The base circuit board is, in particular, arranged on a side of the input device 20 facing away from the user. Furthermore, the receiving element 28 can be arranged directly and / or via additional support elements on the circuit board 31.

[0027] Advantageously, a command can be determined or entered by the user moving the control element 22 in a vertical direction, for example by pressing down on it, and / or by applying pressure to the control element 22 and / or by touching the control element 22, in particular by means of a control unit and / or processing unit and / or computing module on the circuit board. In particular, pressure and / or touch can be applied to the control element 22 to actuate it and / or to enter a command, preferably by a user or their finger or hand. In other words, pressure and / or touch applied to the control element 22 can be interpreted and evaluated as a user command. Advantageously, this pressure can be measured. A sensor or sensors for detecting the pressure applied by the user can be...For example, a classic push button, a pressure sensor, a piezoelectric sensor, an electroactive polymer, optical, resistive, or other suitable sensors can be used. In a further development, push buttons can be arranged or incorporated. For example, the user can be given haptic click feedback when actuating the input device 20. Preferably, this provides the user with click feedback, similar to a push button, so that the user knows that an input has been made. Preferably, the control element 22 can be movable in a vertical direction for actuation. For example, the input device 20 can have a snap disc 44 to generate click feedback and / or to implement a contact switch. The snap disc can be located between the actuator 26 and the control element 22.The snap disc may be arranged on the control element carrier 33 and / or between the actuator 26 and the connecting element 27 and / or between the connecting element 27 and the control element 22 or the control element carrier 33, and / or be designed as part of an actuator assembly. The snap disc can be arranged according to... Fig. 9 trained.

[0028] Alternatively or additionally, the first surface 24 of the control element 22 or the control element circuit board 23 of the control element 22 can be designed as a touch-sensitive surface, for example, by means of capacitive and / or resistive sensors, such as area sensors, whereby an input can be made by touching the touch-sensitive surface. For this purpose, the control element circuit board 23 can have capacitive sensors and / or one or more electrodes. For example, in addition to a central electrode, several electrodes can be arranged at an edge of the control element circuit board 23 to enable different types of interaction, such as a simple tap in the center of the control element 22 as well as moving a finger along an edge of the control element 22 to imitate the function of a rotary switch.

[0029] In a further development, a controller and / or one or more actuators for generating haptic feedback, for example a vibration, and / or an interface for connecting the control element circuit board 23 to the base circuit board 31 can be arranged on the control element circuit board 23.

[0030] In other words, additional electronics can be arranged or integrated in or under the control element 22 or in or on the control element circuit board 23. For example, electronics and / or sensors and / or actuators, such as electrode surfaces, can be applied. This allows, for instance, the integration of touch sensors near the surface and / or the implementation of haptic feedback, lighting, and / or displays for showing information and / or dynamic content on the surface. In a further development, the actuator 26 and / or an actuator on the control element circuit board 23 can be controlled to generate haptic feedback, such as vibration. For example, the control element 22 can vibrate, particularly in different vibration patterns. Furthermore, the control element 22 can provide click feedback.

[0031] A function for entering a command can be activated, in particular, when the control element 22 is in its end position. Preferably, a function for entering a command can be deactivated when the control element 22 is in its home position. In an alternative embodiment, the function can also be activated in the home position, in which case a command can also be entered in the home position.

[0032] In a further development, the input device 20 can have a sensor 34 for detecting a user's approach to the input device 20. In this advantageous embodiment, the sensor 34 is arranged on the control element circuit board 23. Alternatively or additionally, one or more sensors 34 can also be arranged at a different position in or on the input device 20. The input device 20 can have one or more sensors 34, which are, for example, distributed, such as at different positions and / or elements of the input device 20. The one or more sensors 34 can, for example, be arranged in or on the control element 22 and / or in or on the receiving element 28.In other words, one or more proximity sensors 34 can be arranged in the receiving element 28, for example around the control element 22, or in the control element 22 itself, to detect the approach of a user, for example a hand and / or one or more of the user's fingers, from different directions. Preferably, the one or more proximity sensors 34 can be configured as radar sensors, ultrasonic sensors, capacitive sensors, and / or optical sensors. When the sensor 34 detects the approach of a user, in particular a hand and / or one or more fingers, the control element 22 is moved to its end position, in particular by means of the actuator 26. Control of the input device 20 can thus be triggered by the system or by the user themselves, for example by approaching the device with a hand and / or a finger.The sensor 34 can further be configured to detect when a user moves away from the input device 20. If the sensor 34 detects that the user has moved away, the control element 22 can be returned to its initial position.

[0033] Alternatively or additionally, the movement of the control element 22 to its end position can also be triggered by a function or the occurrence of a specific situation. For example, the control element 22 can be moved to its end position when a user is required to provide a specific input, when such input is necessary, and / or when it is expected. If the input device 20 is located in a vehicle, for example, the control element 22 can be moved to its end position when a vehicle occupant is required to provide an input, when such input is necessary, and / or when it is expected. The control element 22 can then be moved back to its initial position when an input has been provided or completed, and / or when no input has been provided by the user for a defined period of time, thus indicating an unintended activation.

[0034] In a further development, the input device 20 can have a lighting device or a backlight, which according to Fig. Figure 1 is not shown. However, the input device 20 can also be configured without illumination. For example, the illumination device can be used to illuminate the control element 22 and / or the area between the control element 22 and the receiving element 28 and / or the area between two or more control elements 22 and / or the gaps in the receiving element 28. The illumination device can be configured, for example, as an LED, light guide, and / or luminous surfaces. Alternatively or additionally, illumination can be arranged in the receiving element 28.

[0035] Advantageously, the input device 20 can include a lighting unit with one or more light sources, wherein the one or more light sources are arranged on the receiving element 28 and / or in the control element 22. Alternatively or additionally, the lighting unit can include one or more light sources and one or more light guides, wherein the one or more light sources are arranged on the base circuit board 31 and the one or more light guides are arranged between the circuit board 31 and the user-facing surface 29 of the receiving element 28. Alternatively or additionally, light sources such as LEDs can be arranged on the control element circuit board 23 and, for example, emit light laterally through translucent sides of the control element housing 21, thereby allowing each control element 22 to be illuminated individually and / or in different colors, and in particular depending on its state.For example, lighting can only be active if input is possible and / or the control element 22 is in its end position.

[0036] In a further development, the input device 20 can have an elastic layer, wherein the elastic layer is arranged on the receiving element 28 on a user-facing side 32 of the input device 20 such that at least part of the control element 22 is covered with the elastic layer. The input device 20 according to Fig. However, 1 does not have an elastic layer.

[0037] Fig. Figure 2 shows a schematic representation of part of an input device 20 according to an embodiment of the present invention. The input device 20 is configured for inputting a command. The input device 20 can, for example, be arranged in a vehicle, for instance according to Fig. 10. The input device 20 according to Fig. 2 is according to the input device 20 according to Fig. 1. The input device 20 has according to Fig. 1 in particular the control element 22, the actuator 26 for moving the control element 22 between the starting position and the end position, the receiving element 28, the connecting element 27 and the base circuit board 31. In a further development, the input device 20 can include a sensor 34 according to Fig. 1. have features for detecting a user approaching and moving away from the input device 20.

[0038] In contrast to the input device 20 according to Fig. 1 is the input device 20 according to Fig. 2 is arranged in the end position. The control element 22 is extended or raised in the end position such that it protrudes at least partially beyond the receiving element 28. This results in a bulge from the receiving element 28 in the end position. In particular, the actuator 26 has moved the control element 22 in a vertical direction. In an alternative embodiment, the control element 22 can be lowered relative to the receiving element 28, thus creating a recess.

[0039] A function for entering a command using the input device 20 can be activated, in particular, when the control element 22 is in its end position. Thus, according to Fig. 2. The function for entering an input is activated because the control element 22 is in its end position. The command or input can be entered according to the explanations below. Fig. 1 can be determined. For this purpose, the control element 22 can be used accordingly. Fig. 1. be trained and have the appropriate sensors or elements.

[0040] Fig. Figure 3 shows a schematic representation of part of an input device 20 according to an embodiment of the present invention. The input device 20 is configured for inputting a command. The input device 20 can, for example, be arranged in a vehicle, for instance according to Fig. 10. The input device 20 according to Fig. 3 is according to the input device 20 according to Fig. 1 and / or Fig. 2. In this advantageous embodiment, the input device 20 is shown in section and comprises at least two operating elements 22, at least two actuators 26 for moving the respective operating element 22 between the starting position and the end position, the receiving element 28, and the base circuit board 31. One of the operating elements 22, here the left operating element 22, is in the starting position, for example according to Fig. 1, and the other control element 22, here the right control element 22 in the end position, for example according to Fig. 2, arranged. The input device 20 can also have more or fewer operating elements 22 and actuators, for example according to the following Fig. 4, Fig. 5, Fig. 6, Fig. 7 and / or Fig. 8.

[0041] The input device 20 may include further elements not shown here, such as individual components and features on the base circuit board 31 and the control element circuit boards 23, for example, electrode pads, contact points, resistors, controllers, connectors, LEDs, and other elements. Furthermore, the input device 20 may include additional elements, such as supports, support elements, and / or connecting elements between the cover element 28 and the base circuit board 31, for supporting and connecting the cover element 28 to the base circuit board 31. These elements stabilize the overall structure of the input device 20.

[0042] The input device 20 is designed to extend one or more control elements 22, for example, interaction elements or buttons, from a surface into their end position. Extending the control element activates the interaction on its surface, while it remains inactive in its lowered or starting position. Furthermore, the input device 20 enables, in particular, multimodal interaction on the control element surface 24, for example, by simple touch, especially in the center of the control element 22, and / or, for example, by radial swiping along an edge of the control element 22. In a further development, the input device 20 can be used to...Actuators 26 of the input device 20 generate haptic feedback when a function is triggered by a touch event, as well as a click and / or grid sensation when swiping along the edge, to simulate the feel of a rotating knob. In an exemplary embodiment, lighting elements can be arranged or integrated between the control elements 22 and / or in the receiving element 28 to visually highlight the active control elements. For example, different light colors can indicate different states and / or functions of the control elements 22. Marking the active control elements with light also facilitates their precise operation in driving situations and minimizes driver distraction from driving tasks.

[0043] The base circuit board 31 can, for example, serve as a carrier for the actuators 26 and other actuator elements and may also have interfaces for connecting the input device 20 to a control unit. A display and / or an additional sensor or sensors, such as radar, ultrasound, camera, capacitive sensor, and others, for detecting the approach of the user's hand to the input device 20 in order to activate it upon detection of an interaction intention, can, for example, be connected to the base circuit board 31 and / or to the connected control unit.

[0044] In this advantageous embodiment, the input device 20 has a lighting unit, wherein the lighting unit comprises one or more light sources and one or more light guides 36. The one or more light sources, for example LEDs, are preferably arranged on the base circuit board 31, but are not shown in this embodiment. The one or more light guides 36 are arranged between the base circuit board 31 and the user-facing surface 29 of the receiving element 28. In this advantageous embodiment, the light guide has a rectangular shape in cross-section, with the sides tapering upwards towards the surface 29 of the receiving element 28. In other words, light sources, for example LEDs, are arranged or mounted on the base circuit board 31, and the light guides 36 can be placed on or arranged above the light sources.The light guides 36 extend, in particular, to the receiving element 28, or to just before the receiving element 28, or through the receiving element 28 to or just before the surface 29 of the receiving element 28, thereby enabling effect lighting on the surface of the receiving element 28. The light sources can be configured as single LEDs, multiple LEDs, or light strips. Alternatively or additionally, the input device 20 can include a lighting unit with one or more light sources, wherein the one or more light sources are arranged on the receiving element 28 and / or in the control element 22. Preferably, in an alternative or additional embodiment, the light sources can be arranged on the underside of the receiving element 28 and / or on the control element circuit board 23 of the control element 22.

[0045] The input device 20 further comprises several actuator assemblies; in this advantageous embodiment, two actuator assemblies are shown. The actuator assemblies include various components to enable the movement of the control elements 22. Each actuator assembly, for example, comprises an actuator 26. In this advantageous embodiment, the actuators 26 are designed as miniature linear actuators that convert a rotational movement of the actuator 26, which can be, for example, an electric motor, into a longitudinal movement via a gear mechanism. A slide 38 connected to the actuator 26, which is in particular part of the actuator assembly, is moved upwards and downwards along the Z-axis by means of the actuator 26. The connecting elements 27, which can in particular be designed as rod-shaped connecting elements 27, are arranged on the slide 38 and are also arranged on the control element 22.This allows the control elements 22 to be moved up and down in accordance with the movement of the carriage 38. In other words, the movement of the carriage 38 is transmitted to the control element 22 via the connecting element 27. The actuator assembly also includes a carrier by means of which the actuator assembly is arranged on the base circuit board 31. Furthermore, the actuators 26 are connected to the corresponding interfaces on the base circuit board 31 via cables 40, in particular power and / or signal cables. Advantageously, the control element circuit board 23 is connected to the interfaces provided for this purpose on the base circuit board 31 via flexible cables. Alternatively, the actuator 26 or actuators 26 can also be directly mounted or soldered onto the base circuit board 31 during the assembly process.This can simplify the construction in particular, as, for example, a support can be omitted, and the assembly steps of the mechanical connection of the actuators 26 to the circuit board 31 as well as the contacting via cables and plug connections can be eliminated.

[0046] The input device 20 further comprises operating elements 22, each operating element 22 comprising an operating element housing 21 or a button housing and an operating element circuit board 23 or a button PCB. The operating element circuit board 23 is mounted in or on the operating element housing 21 such that the operating element circuit board 23 is arranged, in particular, near the first surface 24 of the operating element housing 21. The operating element circuit board 23 comprises, in particular, electrodes, especially electrode surfaces, which are designed such that several capacitive sensors can be generated that enable interaction on the surface 24 of the operating element 22.

[0047] For example, several electrodes can be arranged in a circle around the edge of the control element circuit board 23, allowing the control elements 22 to be used as sliders. This enables the detection of a finger moving along the edge of the surface 24 of the control element 22 or the control element housing 21, allowing the control element 22 to be used like a rotary dial or wheel for inputting commands. For example, a clockwise or counterclockwise movement can increase or decrease media volume or other parameters. Furthermore, an electrode can be arranged in the center of the control element circuit board 23, enabling touch operation, such as tapping the surface. Advantageously, the side of the control element circuit board 23 with the electrodes facing upwards, i.e., towards the user, is oriented upwards.especially in the direction of the surface 25 of the control element housing 21. Further components can be arranged on the back of the control element circuit board 23, such as a controller for evaluating the touch events and / or one or more actuators for generating haptic feedback when user input is detected and / or one or more interfaces, for example, for connecting the control element circuit board 23 to the base circuit board 31 via cable 42. On the side of the control element housing 21 opposite the user, a fitted component is arranged as a control element carrier 33 to the control element housing 21 in order to reinforce the thin-walled structure of the control element housing 21 and to create a connection point for the connection with the actuator 26, in particular with the connecting element 27 or the carriage 38.In other words, the control element carrier 33 is arranged on the control element housing 21, with the connecting element 27 also being arranged on the control element carrier 33. This allows the movement of the actuator 26, and thus of the carriage 38 and the connecting element 27, to be transmitted via the control element carrier 33 to the control element 22. The control element carrier 33 has, in particular, a central receptacle for the rod-shaped connecting element 27 or plunger. The control element carrier 33 also has openings for cables 42 or data / power lines of the control element circuit boards 23.

[0048] The control element carrier 33 can be connected to the connecting element 27, for example, by positive locking, material locking, and / or force locking. For example, the control element carrier 33 can be connected to the connecting element 27 by screwing, snapping, hooking, or other suitable connections.

[0049] To ensure that the buttons are flush with the surrounding surface when inactive, a corresponding lower stop is arranged on the receiving element 28, against which the control element 22 can be moved. This guarantees a consistently uniform and mechanically stable resting position in the initial position.

[0050] The stop for the operating elements 22 is realized in the form of inclined flanks at openings of the receiving element 28, in particular the openings of the receiving element 28 into which the operating elements 22 or the operating element housings 21 are inserted. In other words, an inclined flank is provided at the edge of the openings of the receiving element 28 into which the operating element housings 21 are inserted. The corresponding counterpart of the inclined flank is arranged on the operating element housing 21, in particular at an edge or an upper edge of the operating element housing 21. When the operating element 22 is lowered, it is lowered in such a way that the inclined flank of the operating element housing 21 contacts or abuts the inclined flank at the opening of the cover element 28. The inclined flanks can, in particular, be arranged all around the operating element 22.When the buttons are lowered, a positive fit is created and the operating elements 22 are pressed against the opening flanks of the receiving element 28 in a circumferential manner. This has the additional advantage that no dirt can penetrate.

[0051] Optionally, a snap disc can be installed in the carriage 38 and / or in another element of the actuator assembly, according to the snap disc according to Fig. 9, are inserted to produce a clicking sound and feel when the operating element 22 is pressed, and thus when the connecting element 27 or plunger is pressed against the snap disc. Advantageously, the snap disc can be electrically contacted and / or an electrode, also electrically contacted, can be arranged under the snap disc, allowing the snap disc to be used additionally as a contact switch.

[0052] In this advantageous embodiment, each control element 22 has its own actuator 26 or its own actuator assembly, whereby the control elements 22 can be controlled differently or independently of each other and can therefore be moved independently of each other between the starting position and the end position.

In this advantageous embodiment, the top surface of the control elements 22, in particular the side visible to the user, is formed as a hexagon with rounded corners. The control elements 22 can also have other shapes. The control elements 22 are arranged such that a single one is located in the center and two are arranged on each of the opposite sides.
