In the retracted position, the receiving element 38, the upper edge 28 of the support frame 26, and the first surface 34 of the cover plate 32 are arranged on one plane. In other words, the support frame 26 and the cover plate 32 disappear within the receiving element 38. In particular, the upper edge 28 of the support frame 26 can be flush with the upper side of the receiving element 38. As a result, in the retracted position, there is no bulge from the receiving element 38 due to the support frame 26 and the cover plate 32. The receiving element 38 can also be designed, for example, as a housing and / or as a carrier.In an exemplary embodiment, the receiving element 38 can be part of the dashboard of a vehicle, a storage compartment and / or an armrest, in particular in a center console, of a vehicle, or can be arranged in or on a dashboard of a vehicle, a storage compartment and / or an armrest, in particular in a center console, of a vehicle. In the extended position, for example, shown in . Fig. 2 and / or Fig. 3, the upper edge 28 of the support frame 26 protrudes from the receiving element 28.

[0029] The base plate 22, the support frame 26, the push button 30, and the cover plate 32 can, for example, be referred to as an operating element. The operating element can be received in the receiving element 38.

[0030] Furthermore, the input device 20 has an elastic layer 40.

[0031] In a further development, the elastic layer 40 can be attached to the receiving element 38 by means of a material-to-material connection. The material-to-material connection can be formed, for example, as an adhesive connection.

[0032] In an advantageous embodiment, the elastic layer 40 can be designed to be deformable for moving the base plate 22, in particular with the other components, into the extended position and for actuating the push button 30. In other words, the elastic layer 40 can be deformed and thus, in particular, stretched when the support frame 26 and the base plate 22 are extended. For this purpose, the upper edge 28 of the support frame 26 can have rounded corners or be rounded, whereby the elastic layer 40 can rest against the upper edge 28 of the support frame 26. The extended position is, for example, according to Fig. 2 and / or Fig. 3 shown.

[0033] In a further development, the push button 30 can be designed to be operable in the extended position. Advantageously, the push button 30 can be designed to be non-operable in the retracted position. For this purpose, the push button 30 can, for example, be latched in the retracted position. In an alternative embodiment, the push button 30 can also be actuated in the retracted position.

[0034] In an advantageous embodiment, the input device 20 can have at least one sensor 44 for detecting a user approaching the input device 20. The sensor 44, which is designed to detect an approach, can be designed, for example, as a capacitive sensor or as an optical sensor. Alternatively or additionally, the proximity sensor 44 can be designed as a radar sensor, ultrasonic sensor, capacitive sensor and / or optical sensor. Alternatively or additionally, the proximity sensor 44 can be integrated into the elastic layer 40. When the sensor 44 detects the approach of a user, the base plate 22, in particular with the components arranged thereon, is moved by the actuator 36 along the Z-axis 24 into the extended position.In a further development, the sensor 44 can be designed to detect a user's departure from the input device 20, wherein the base plate, in particular with the components arranged thereon, is moved into the retracted position along the Z-axis 24 by means of the actuator 36 when a user's departure is detected by the sensor 44. In other words, the base plate 22 with the support frame 26 arranged thereon, the push button 30 arranged thereon, and the cover plate 32 arranged on the push button 30 is raised or moved into the extended position when it is detected that a user, for example a hand or a finger of the user, is moving towards the input device 20.If it is detected that the user, for example the hand or the finger of the user, is moving away from the input device 20 again, the base plate 22 with the support frame 26 arranged thereon, the push button 30 and the cover plate 32 arranged on the push button 30 can be retracted or moved into the retracted position.

[0035] Alternatively or additionally, the movement of the base plate 22 with the components arranged thereon into the extended position can also be triggered by a function or the occurrence of a specific situation. For example, the base plate 22 with the components arranged thereon can be moved into the extended position when a user requests, requires, or expects a specific input. If the input device 20 is arranged in a vehicle, for example, the base plate 22 with the components arranged thereon can be moved into the extended position when the vehicle occupant requests, requires, or expects an input.

[0036] In a further development, the cover plate 32 can be designed as a touch-sensitive surface for entering the command. For example, the cover plate 32 can have sensors for detecting a touch, wherein the sensors can be designed, for example, as capacitive sensors or as resistive sensors.

For example, textile fibers can be incorporated into the elastic layer 40, wherein sensors are incorporated into the textile fibers.the fibers themselves are functionalized, for example, by conductive coatings and represent the sensors.

[0037] In other words, the input device 20 can be described as an upwardly morphing element that can be raised to enhance the tactile interaction surface and that enables the operation of a mechanical button, in particular with haptic click feedback, on the resulting elevation. In addition, touch interaction can be enabled on the resulting elevation. The input device 20 comprises the base plate 22, which can be designed, for example, as a printed circuit board or PCB for the purpose of simple functional integration. The input device also comprises the actuator 36 arranged beneath the base plate 22, by means of which the base plate 22 can be raised and lowered again. A circumferential support frame 26 or support edge is applied or arranged on the base plate 22 and defines the external geometry of the input device 20 orof the operating element and can be shaped accordingly, for example, round, oval, rectangular and other shapes. At least one push button 30 is arranged within this support frame 26, on which the cover plate 32 is applied or arranged. The cover plate 32 is designed on all sides such that it extends almost to the support frame 26 or the upper edge 28 of the support frame 26 and the surface 34 of the cover plate 32 is flush with the upper edge 28 or the upper edge 28 of the support edge 26. This enables movement of the cover plate 32 in the direction of the Z-axis 24 or in the z-direction within the support frame 26 without tilting. The structure is arranged in particular within the receiving element 38 or the support structure, which basically represents the surface surrounding the operating element. A flexible layer 40 or decorative cover layer can be stretched over this surface, thereby covering the operating element.The flexible layer 40 can be made of leather, artificial leather, textile and in particular bi-elastic.

[0038] Advantageously, in an inactive state, the overall construction and position of the actuator, in particular the stops required for positioning accuracy, can be adjusted so that a completely flat surface is created and the input device 20 cannot be perceived by the user. If, for example, the base plate 22 is raised by the actuator 36 due to the approach of a user's hand and / or triggered by the system, a tactile knob or button is created.

[0039] Advantageously, the input device 20 can be designed as a downward-morphing control element with integrated click haptics by incorporating a push button with a freely suspended cover or cover plate. This allows for the creation of tactile interaction surfaces that are lowered relative to the surrounding surface, enabling not only touch interaction, but also classic actuation by applying force with a finger, with haptic feedback similar to that of a conventional click button.

[0040] In a further development, in addition to the at least one push button 30, further components required for the interaction can be accommodated in the resulting cavity between the base plate 22, the support frame 26 and the cover plate 32 arranged or mounted on the push button 30 and, for example, interconnected on the PCB. For example, a light or a lighting unit can be arranged on, in, or under the base plate. Alternatively or additionally, the or a further lighting unit can be arranged on or in the support frame 26 and / or the cover plate 32. The lighting unit can, for example, be designed as one or more LEDs or light-emitting diodes, OLEDs, or comprise one or more LEDs or light-emitting diodes, OLEDs. For example, the cover plate 32 can be at least partially transparent.This allows a lighting unit arranged on the base plate 22 to shine through the cover plate 32 and thus be visible to a user. Additionally or alternatively, the support frame 26 can also be at least partially transparent, which allows for the creation of peripheral edge illumination of the control element when the one or more lighting units are placed in or under the support frame 26.

[0041] Fig. Figure 2 shows a schematic representation of an input device 20 according to an embodiment of the present invention. The input device 20 is designed to input a command. The input device 20 can be arranged, for example, in a vehicle, for example according to Fig. 6. The input device 20 according to Fig. 2 is according to the input device 20 according to Fig. 1. The input device 20 according to Fig. 2 shows the components of the input device 20 according to Fig. 1, namely a base plate 22, a support frame 26, a push button 30, a cover plate 32, an actuator 36, a receiving element 38, and an elastic layer 40. In an advantageous embodiment, the input device 20 can further comprise one or more sensors 44. The base plate 22, the support frame 26, the push button 30, and the cover plate 32 can, for example, be referred to as an operating element.

The extended position can also be referred to, for example, as the operating position. In the extended position, the support frame 26 and the cover plate 32 are arranged at least partially outside the receiving element 38 and thus protrude from the receiving element 38. This results in a bulge through the support frame 26 and the cover plate 32 protruding from the receiving element 38 in the extended position.

[0043] In the extended position, the elastic layer 40 preferably rests on the edge 28 of the support frame 26 and the cover plate 32. In other words, the elastic layer 40 is arranged on a side facing the user such that at least a portion of the support frame 26 and the cover plate 32 is covered with the elastic layer 40. In other words, the elastic layer conforms to the shape of the edge 28 of the support frame 26. In the extended position, the elastic layer 40 forms a bulge, which bulge can in particular take on the shape of the edge 28 of the support frame 26. In other words, the elastic layer 40 is deformed in the extended position such that a bulge is formed by the edge 28 of the support frame 26. As a result, the shape of the edge 28 of the support frame 26 in the extended position is preferably visible to a user through the elastic layer 40.

[0044] By bonding the decorative surface to the receiving element 38 and the support frame 26 or the support structure 26 and to the movable cover plate 32, the elastic layer 40 or the decorative material can stretch in the region of the support wall or on a wall of the support frame 26, thus creating a geometry with at least approximately sharp contours. The elastic layer 40 or the decorative material can deform, in particular, depending on the extensibility and / or elasticity and / or stiffness of the elastic layer 40. In an advantageous embodiment, for example, an edge around the operating element and / or on the support frame can be unglued or not glued, so that more material reserve is available for the expansion of the elastic layer 40.

[0045] A function for entering a command by means of the push button 30 can be activated in particular when the operating element and thus the base plate 22, the support frame 26, the push button 30 and the cover plate 32 are arranged in the extended position. Preferably, a function for entering a command by means of the push button 30 can be deactivated when the operating element and thus the base plate 22, the support frame 26, the push button 30 and the cover plate 32 are arranged in the retracted position. In other words, the push button 30 is according to Fig. 2 is activated when the operating element and thus the base plate 22, the support frame 26, the push button 30 and the cover plate 32 are in the extended position. This allows a force to be applied, which, for example, according to Fig. 3 is shown.

[0046] In a further development, the input device 20 can comprise a sensor 44 according to Fig. 1 for detecting a user approaching the input device 20. In other words, the approach of a user can be detected by means of the sensor 44. If the approach of the user, in particular a hand, one or more fingers, or a foot, is detected by the sensor 44, the base plate 22 with the components arranged thereon is moved into the extended position by means of the actuator 36. The sensor 44 can further be designed to detect a user moving away from the input device 20. In other words, the sensor 44 can furthermore detect a user moving away from the input device 20. If the sensor 44 detects a user moving away, the base plate 22 with the components arranged thereon can be moved into the retracted position.Alternatively or additionally, the system, for example, the vehicle system, the base plate 22 with the components arranged thereon, can be independently moved into the extended position by means of the actuator 36, for example, when it detects that a user input is necessary and / or expected. Alternatively or additionally, the system can move the control element back into the retracted position when an input has been made or completed, or when no user input has been made for a defined period of time, and therefore unintended activation can be assumed.

[0047] In other words, the input device 20 can be designed as a push button that, in the extended position, protrudes from the receiving element 38 when operation by a user is necessary, desired, and / or expected. In the initial situation, the area in which the operating element or input device 20 is arranged is a flat surface.

[0048] In other words, the input device 20 comprises a flexible surface or elastic layer 40, which, through underlying mechanically adjustable elements or the actuator 36, can assume the shape of a round, oval, or square element—here, the shape of the support frame 26—which externally resembles a conventional button, switch, or rotary push button. This deformation is driven electronically and / or mechanically and occurs situationally, for example, when the adjustment of vehicle settings or navigation in the vehicle's operating system is to be simplified by an input device 20. The described deformation can be initiated manually by the user via a haptic signal, gesture, or speech, or automatically by a proximity sensor 44. When pressure on the surface is detected, an input can be confirmed.

[0049] In other words, shaping or morphing the input device 20 or the support frame 26 and the cover plate 32 from the surface is based, in particular, on an actuator 36 below the surface to be deformed or the elastic layer 40, which can push the base plate 22 upward, thereby deforming the elastic layer 40. The elastic layer 40 can be designed, for example, as a decorative layer, for example, as a textile covering, artificial leather, or other suitable materials.

[0050] The elastic layer 40 must be designed to be appropriately elastic and have sufficient restoring force to be able to reproduce the desired degree of deformation without damage, particularly depending on the dimensions of the support frame 26 and the travel path of the support frame 26, and to form a smooth, wrinkle-free surface again upon retraction. The actuator 36 for the up-and-down movement of the base plate 22 can be implemented in a variety of ways and depending on requirements, in particular depending on the force required to deform the surface material, the available installation space, the desired movement patterns, the noise generation, and / or other factors. For example, the actuator 36 can be designed as an electromechanical, pneumatic, hydraulic, electromagnetic, or other actuator. For example, the actuator 36 can be designed as an electromechanical servomotor.

[0051] Fig. Figure 3 shows a schematic representation of an input device 20 according to an embodiment of the present invention. The input device 20 is designed to input a command. The input device 20 can be arranged, for example, in a vehicle, for example according to Fig. 6. The input device 20 according to Fig. 3 is according to the input device 20 according to Fig. 1 and / or Fig. 2. The input device 20 according to Fig. 3 shows the components according to the input device 20 according to Fig. 1 and / or Fig. 2, thus a base plate 22, a support frame 26, a push button 30, a cover plate 32, an actuator 36, a receiving element 38 and an elastic layer 40. In an advantageous embodiment, the input device 20 can further comprise one or more sensors 44. In this advantageous embodiment, the input device 20 is according to Fig. 2 shown in the extended position.

[0052] Preferably, the push button 30 of the operating element is designed to input a command by means of a force applied to the cover plate 32. In other words, a user can make an input and thus enter a command by pressing the cover plate 32, for example with a hand or a finger 46. The hand or the finger 46 are shown schematically in this advantageous embodiment. The force on the cover plate 32 can be applied by a person or the user. Touching by a person can be detected, for example, as pressing and / or deforming and / or pressing in by a hand or one or more fingers or a foot of the person. For example, a user can exert pressure on the cover plate 32 and thus on the push button 30 using one or more fingers 46.In other words, the user can press down on the cover plate 32 using their finger 46, whereby the force is transferred through the movable cover plate 32 to the push button 30. The push button detects the pressing action. In other words, an operation can be performed with a certain amount of pressure on the surface, allowing the user to press down the cover plate 32 and thereby trigger the push button located underneath. This provides the user with haptic feedback, in particular. In a further development, for example, a value for an applied force can be determined.

[0053] Advantageously, the push button 30 can be designed to be movable from a first, non-actuated position to a second, actuated position. Advantageously, the upper edge 28 of the support frame 26 and the first surface 34 of the cover plate 32 are arranged in a plane in the first, non-actuated position of the push button. The first, non-actuated position can, for example, be Fig. 2. By actuating, thus pressing the user on the cover plate 32, the cover plate 32 and thus the push button are moved from the first, non-actuated position into the second, actuated position, shown in this embodiment according to Fig. 3, moved.

[0054] In a further development, the cover plate 32 and / or the region of the elastic layer 40 covering the cover plate 32 can be designed as a touch-sensitive surface, in particular as a touch input surface. In other words, the cover plate 32 and / or the region of the elastic layer 40 can additionally have a multi-touch sensor system, for example, with a capacitive sensor surface, in particular to enable user inputs. The user inputs can be designed, for example, as gesture interaction, letter input, or other forms.

[0055] In a further development, a light grip of the side surfaces of the support frame in the extended state with two or more fingers can detect a clockwise or counterclockwise rotational movement, for example, to scroll through a list or zoom in on a map. This interaction preferably occurs without actually rotating the support frame 26. The user can glide their fingers over the surface of the elastic layer 40 on a circumference of the support frame 26, wherein either the corresponding area of ​​the elastic layer 40 or the underlying side wall of the support frame 26 has a flat touch sensor, for example, designed as a capacitive sensor, and can thus detect the touch and movement of the fingers.

[0056] In a further development, the input device 20 can provide haptic feedback. For example, the support frame 26 or the cover plate 32 can vibrate, in particular in different vibration patterns. For example, noticeable grid points, for example when a rotational movement is detected, can be provided to the user by means of the haptic feedback. Furthermore, when the cover plate 32 is pressed, haptic feedback corresponding to a push button can be given. In order to simulate a rotational movement of the extended element, the input device 20 can have virtual haptics in combination with a touch sensor system. Actual rotation is limited by the surface material. If the sensor, for example in the form of a slider along the extended support frame 26, detects a radial movement of two or more fingers around the element, in particular as if the user were holding the support frame 26 in their hand orIf the user takes the handle between their fingers and attempts to rotate it, vibration elements along the outer wall of the support frame 26 or a central vibration element can generate haptic feedback that feels like a click to the user, creating the illusion of a gently clicking rotation. Furthermore, this rotation can be detected, and a corresponding action or command can be triggered.
